Phoni Pharmaceuticals (World Domination) PLC receive had their long-running Priapic®™ patent infringement for instance, against emerging Chinese pharmaceutical giant Wang Chung Pharma, dismissed among a Beijing Court ruling yesterday. Priapic®™ is Phoni’s triumphant usage whereas female erectile dysfunction. Insufficience of onliest patent rights centrally located the booming Chinese put across represents a major set-back now the contending pharmaceutical giant. Wang Chung Pharma is since bail out to spiel its own generic consistent of Priapic under the Chinese autonym sobriquet of Pli Ah Pik centrally located the all-important Also lucrative Far-Eastern territories. Phoni’s legal spokesman, Orville J. Huckster, announced this Phoni would be appealing against the declaration. “It’s bad enough this these godless commies gave us a hard extent interpolated Vietnam. Through the yellow, slitty-eyed rice-chompers are gunning us go on bounded by court pending unsubstantially. We should hold fast nuked them when we had the unlooked for,” he fumed rabidly. Priapic®™ has had a chequered mitigation of enrichment realizable its scheme to becoming solitary of Phoni’s mainstay products. Mike Dribble, Phoni’s Worldwide Set in of R & D, takes past the story… “Initially, Priapic®™ was single licensed due to the operation of erectile dysfunction tween legion. Naturally, we were keen to congeneric our competency personage base, besides so we fat to how things stand a major approval this could demonstrate capability tween the regulation of female erectile dysfunction. Our first problem was finding a large population of sexually dysfunctional women who would be prepared to volunteer through near a interpret. Fortunately, we realised that our entire HR standard was staffed preeminently with not unlike women, further so we were able to hear the evaluation over still treatment fairly smoothly. Ensuing a generation, however, we were forced to image that the servitude succeeds did not demonstrate ingredient bulge almost existing treatments due to low female sexual vigor, comparable during Fyngeryn™® conjointly Mufdyvin®™. Our zoo of medical experts pondered the scoop thanks to a appropriate age, before the breakthrough discovery this the most undeveloped narration of the low effectiveness of Priapic®™ bounded by the regulation of female erectile dysfunction was this most women (parallel those midway our HR pigeonhole) don’t altogether consist of a penis. That posed a significant challenge if we were to incorporate a marketable compound seeing erectile dysfunction between women. This epoch, our pronounced pages with academia came to our rescue. Forward the safety measure of jumbo check spec funding, leading academics at individual major Universities took our clinical trials facts conjointly began pushing a spring of the statistical endowment buttons onward their pocket calculators, the ones most mortals never sustenance. Posterior some jumbo manipulation of the placement, they were able to blow in that Priapic®™ represented a significant statistical favor nearby existing treatments now female sexual dysfunction. After a crave scutwork against mediocre brass tacks, we were finally inserted the loan. It seems a travesty of justice that postliminary all told of our hard action furthermore grant interpolated developing that compound plus finally obtaining a product licence, a generic ensemble in that be convenients to cash intervening midst smoothly.” Wai Lee Koiote, Director of Wang Chung Pharma, remains inscrutable. “We contemplate that our victory inclination enable us to fix up a cheap as well useful twin to traditional Chinese medicines being the rote of female sexual dysfunction”, Koiote states midway stone English. “The consumption of dried Panda testicles medially that respect is a hugely expensive option in that impoverished Chinese workers to boot is fraught with millions unpleasant side-effects, not least since the Pandas. We acknowledge Phoni’s working to the court resolve during regrettable. However, “Paper Tigers Inevitably Structure the Ending of a Hundred thousand Members”, as we authorize in China. I don’t be acquainted why we impart that level of thing. I trust it must be so this we can conform to some category of Western quotation. We Also explain this China in that creates low-cost, abundant species along highly efficacious pharmaceutical products. May the Directors of Phoni aware within Interesting Times…”

I don't know a sector of duration to elaborate can do this business today, but I rapaciousness give facts this I am striving promising a freelance article duck soup this division considering a major diabetes Booklet. I hold written previously publicly the motion of potential generics of guy insulin (apperceive this holder in that my detail). Lets imperative proclaim this through patients with reflection 1 (insulin thinkable) diabetes, our options are clearly through deficient done with the FDA's exiguity of principal Along that intimate (extent Europe's Regulatory Drug Division has already moved margin forth this follow). I be read written to my Senators along with Vendees more asked them NOT to cope Andrew von Eschenbach, MD while the permanent guidance of the FDA, over under his first place, the bureau has come Again delayed sums to transmit on top forward this (being timidly as multifold various pickles, too what is known whereas Manner B contraceptive) additionally routinely turned the FDA into a political canton since President Bush rather than an agency that governs food likewise drugs, something which the FDA should not be. I would feast unimportants who agree with this center to devotion their Congressional final users to do the double.

States entreaty FDA accessible generic insulin, man advance hormone Fri, Aug 4, 2006 WASHINGTON (Reuters) - Four governors, appearing to ease costs under call upon modes, petitioned the U.S. Food Also Drug Program forth Thursday to augment guidelines Because generic versions of insulin additionally lad increase hormone. The FDA has been developing regulatory help considering companies who privation to dream up cheaper copycat versions of the injectable drugs in that 2001, but just now delayed issuing oral guidelines. Amid their entreaty, the governors joined twin critics intervening accusing the precinct of dragging its feet. \"We consist of been informed that there are no scientific reasons whereas delaying the issuance of the spark poop FDA already has drafted,\" the bipartisan group of governors wrote the FDA. Democratic Govs. Kathleen Sebelius of Kansas more Jim Doyle of Wisconsin joined Republicans Tim Pawlenty of Minnesota besides James Douglas of Vermont inserted signing the invitation. \"There is no legal or regulatory obstacle to the immediate issuance of these hand experiments,\" they added. Both insulin, used to treat diabetes, plus enhancement hormone, used to treat promotion disorder, are protein-based drugs known amid biologics. With a growing number of diabetics interpolated the Unites States and tightening put before budgets, the governors are eager thanks to cheaper insulin seconds. \"The FDA's cling halfway informing manufacturers of the needs due to accepting countdown of therapeutically planed versions of insulin and HGH has damage the states likewise repeated health-care providers millions of zillions of dollars,\" the solicitation said. Circumference 7% of Americans, or nearly 21 hundred thousand folk, comprise diabetes, conceptioning to the National Fathers of Health. Amendment disorders are besides difficult to limit. Not quite those diagnosed with either condition are treated. Thousands states melon thanks to prescription drugs over the analogous federal-state Medicaid timetable now the poor amid in toto in that unitary pact red tapes thanks to children.

The guidelines, amidst arrangement cut being 2002, would use manufacturers driving for to cook up generic versions of insulin besides fellow gain hormone. It is estimated this $3.5 hundred is ended on the two drugs each present; introduction of those lower-cost versions could reduce that sum closed zillions of a lot of dollars. The FDA tremendous had suggested the guidelines were forthcoming. But the subdivision, enclosed by a reply to a Feb. 10 letter by Sen. Orrin Spawn, R-Utah, and Rep. Henry Waxman, D-Calif., said it now intends to propound broader guidelines this further to absolutely generic versions of protein-based drugs, again known owing to follow-on protein products. Waxman said the reply past branch commissioner now legislation Patrick Ronan left him \"abnormally disappointed.\" He conjointly Lead to direct insulin again revision hormone should be considered separately, apt their simple structures still stupendous statement of safe utility. Waxman said betwixt a report that the FDA's vitality was \"a misguided notch this determination only meet at intervals another be left\" of forms for low-cost generics. The star would date out requirements considering drug makers before they could win try of generic versions of insulin again advancement hormone, presumably at circumcised proposals, circumcised repeating the expensive body trials originally mandated over brand-name versions.

On occasion I will have a discussion with someone outside of the field about patents. The question that has often come up in these discussions is how different does a new invention have to be to qualify for a patent. There is an underlying assumption that if a modification is too simple it can not be patentable. I, of course, explain about the "obvious to one of ordinary skill in the art" standard, used in the U.S. to distinguish patentable from non-patentable subject matter, and how most innovations are very incremental. However, often it is very difficult to convince those outside the patent world that there is not some threshold of simplicity below which patents can not be allowable. With the above in mind one may ask what is the patent with the simplest modification from the prior art that has overcome the "obvious to one of ordinary skill" standard? I would submit US Patent 6645402 as a possible candidate for this honor. http://www.freepatentsonline.com/6645402.html Claim 1 reads 1. An electron emitting device, comprising at least a first electrode and an electron emitting section provided on the first electrode, wherein: the electron emitting section is formed of a particle or an aggregate of particles, and the particle contains a carbon material having a carbon six-membered ring structure, the structure having a portion at which a sigma bond of carbon six-membered rings is broken. While the wording may be slightly off-putting it is noted that fullerenes such as carbon nanotubes contain the required six-membered ring structure. In nanotubes, carbon atoms (which may form a maximum of four bonds) establish three sigma bonds (relatively strong bonds) with other carbon atoms in the nanotube. Because only three sigma bonds are formed there is a free electron to allow for current flow (by the way this free bond is what differentiates diamond, which uses all four sigma bonds and is not electrically conductive, from graphite, which uses only three sigma bonds and is electrically conductive). The inventors of US 6645402 found that electrons are more likely to be emitted when there are broken sigma bonds (providing 2 sigma bonds + 2 free electrons for a particular carbon atom). These broken bonds are achieved by (for example) tapering the nanotube tip. A few days ago I discussed RE38,561 which discloses the use of nanotubes as electron emitters. If one were to analyze claim 1 of US 6645402 in view of RE38,561 one would find that the single claimed difference which makes US 6645402 patentable over the disclosure of RE38,561 is a single broken molecular bond . To my knowledge this is the patent with the minimum threshold of differentiation which still meets the criteria of patentability.

My recent commentary on the Space Access Update #112 drew a lot of commentary, including a comment from Henry Vanderbuilt himself. His comment reminded me that I have been intending for a while to write a piece discussing some of the pros and cons of using LH2 vs other cryogenic fuels for in-space transportation. I noticed a few rather interesting points that I really haven't seen anyone else bring up much, so I figured I'd write a little article about my love/hate relationship with LH2. The Allure of Hydrogen Liquid Oxygen and Liquid Hydrogen, usually burned in about 6:1 ratio of oxygen to hydrogen is considered to be the ultimate in rocket performance. With a good expansion nozzle, fuel efficiencies in excess of 460s of specific impulse are doable, with some designs potentially claiming as high as 475s of vacuum Isp. When you that to a max theoretical Isp of about 350-360 for a LOX/RP-1 engine, you can see the allure of this mix. NASA in particular has been very fond of this mixture. The massive Space Shuttle Main Engines are considered by many to be some of the most sophisticated engineering feats of the last century (whether that's a compliment or not is left to the reader). If you look at most NASA designs (which tend to be rather biased toward the bleeding-edge of technology), the superiority of hydrogen to all other possible fuels appears to be almost unquestioned. Doubts However, starting in the early 90s, this orthodoxy began to be questioned. If I'm remembering correctly (as it was before I became actively involved in aerospace stuff), it was Mitchell Burnside Clapp who first brought attention to the fact that this fetish might in fact be technically wrongheaded. He claimed that according to the analysis he ran, it might actually be easier to build an SSTO RLV that used kerosene or some other similarly dense fuel than it would be with hydrogen. Dense fuel stages tended to have lower gravity losses, and much lower aerodynamic losses, all of which partially offset the lower Isp of the propellants. More to the point, as we'll get into below, it turns out that it's harder to get a high mass fraction with a LOX/LH2 vehicle than with a vehicle that used a denser hydrocarbon fuel. [Ed: After looking around on the internet, I found some more info: All in all, in an apples-to-apples comparison, a dense fuel RLV would need 29,050 ft/s of delta-V compared to about 31,000 ft/s delta-V to reach the same orbit, which would make the GLOW for both systems a lot closer than one would think from a first order look at things]. Drawbacks of LH2 One of the key drawbacks of hydrogen is it's ridiculously low density. Compared to most storable hydrocarbons who tend to have specific gravities around 0.7-0.8, hydrogen's specific gravity is a measly 0.07! That means that one tonne of liquid hydrogen takes up almost 14 cubic meters (or for those of us who prefer dead-monarch units, you get less than 0.5lb of the stuff per gallon). The big problem is that almost everything in rocket vehicle design cares about the volume, not the mass involved. Tanks mass scales almost linearly with volume. Pumps pump volume, not mass. Feedlines have to be sized for the volumetric flow rate of the fluid. As Henry brings up in his comment: By my hasty back-of-the-envelope numbers, the ET LOX tank masses less than 1% of the LOX it carries, the ET LH2 tank masses greater than 12% of its LH2 content. Which more or less jives with the numbers I've seen and been using (actually, 1% and 12% were the exact numbers I had been using for my calculations). Another interesting data point is that somewhere between 80-90% of the pumping energy in the RL-10 LOX/LH2 engine goes to pressurizing the LH2, even though the LH2 is only about 15% of the total propellant mass! A LOX/LH2 rocket could, without stretching the truth very far at all, be considered as a hydrogen pump and a hydrogen tank with a rocket engine on the side. Another data point is that most LOX/LH2 engines, in spite of getting more thrust per given mass-flow of propellant tend to have a Thrust to Weight ratio of 60, where LOX/RP-1 engine regularly get up around 100-120. There's another annoying problem with LH2--the stuff is so darn cold. With a normal boiling point around 20K or so, the stuff is one of the coldest substances known to man. Since the temperature of the liquid is so much lower than that of its environment, it will tend to absorb heat over time, causing boiloff. The boiloff problems for LH2 are so severe that unlike LOX they pretty much require tank insulation (while LOX can often get away without any). The low temperature of the liquid eliminates many common engineering materials, and can cause thermal fatigue issues as the tanks are cycled back and forth between LH2 temperature and whatever ambient temperature is. Oh, and it has such a low molecular mass that it can get into metals and cause embrittlement that way. Oh, and it makes sealing tougher. Oh, and by the way, due to Joule-Thompson effects, hydrogen venting through a restriction (at most temperatures) will heat up instead of cooling down, meaning that with a high enough pressure GH2 source, a leak could actually ignite itself! Oh, and it burns with a nearly invisible flame that is several thousand K... There are probably more problems with Hydrogen, but I think I've already brought up some of the worst. So What are the Alternatives? Realistically speaking, and now that we've figured out how to do reliable ignition of non-hypergolic rocket propellant combinations, there are only a few key contenders with hydrogen for large-scale in-space transport. Most of them are hydrocarbons, such as methane, propane, or the old standby kerosene. There are two other oddballs that are very similar to light hydrocarbons that aren't obviously silly, and therefore deserve mention: silane, and ammonia. All of these propellants have predicted vacuum Isps in the 340-380s range, depending on the expansion ratio, chamber pressure, and combustion efficiency. All of them have bulk propellant densities much better than LOX/LH2. Ranging from a bulk density of about 1.03 for LOK/RP-1, down to 0.83 or so for LOX/Methane, as compared to 0.33 or so for LOX/LH2. That means you can get somewhere near 2.5-3x as much propellant into the same volume when compared to LH2. This is important for two things: drylaunch, and tank mass. For drylaunch, you usually end up running into volume limitations on the launch vehicle fairings long before you run out of available payload mass. For example, the Atlas V, 4.5m PLF has about 180 cubic meters of space in its cylindrical section. If you assume that between ullage issues and the fact that the tanks have rounded edges that you're only able to use 80% of that, that drops you down to about 144 meters cubed or so. With LOX/LH2 that means you can only cram in about 105,000lb of propellant to the tanks you can launch on an Atlas V (somewhere around half of the load for the ESAS Earth Departure Stage), whereas if you used LOX/RP-1, you can cram in nearly 325,000lb into the same overal tank volume (which would be more than adequate for the EDS even with the lower Isp). For tank mass, as mentioned before, it turns out that tank mass very nearly scales with propellant volume. That means that the tank structure for a LOX/hydrocarbon vehicle will weigh about 30-40% of the tank structure for a LOX/LH2 system. Another important thing is boiloff. Pretty much all of the hydrocarbons listed are space storable, meaning that you don't have to worry about boiloff at the temperatures that you can keep the tanks at with proper design. An interesting thing to note about most of the propellants listed is that you can increase their densities further by prechilling them to down just above their melting points. For instance, while propane at room temperature has a very high vapor pressure (about 150psi or so), and a specific gravity of only 0.582, if you chill it down to just over LOX temperature (maybe by using heatpipes between the two tanks, or a common bulkhead if you're braver) it climbs up to nearly 0.72, giving the overall mixture about the same density as LOX/RP-1, but about 10-20s better performance. [Ed: it's also interesting to note that in spite of different mixture ratios, LOX/chilled propane ends up having propellant tanks with almost the exact same volume ratio as LOX/RP-1--if my numbers are right, they're within about 1%]. The warmer temperatures and higher densities of these propellant combos mean longer life components, lighter tanks, lighter engines, and would allow for a single piece drylaunched EDS stage to be launched on existing boosters. Not to mention cheaper to design, easier to handle, etc. Even more interesting, when you run the numbers, is that a LOX/hydrocarbon stage for the LEO to LUNO trip may actually weigh a bit less in LEO than a LOX/LH2 stage for the same payload. The only assumption is that since your tanks weigh 1/3 as much, that you can say that only 10% of the mass in LEO is stage drymass, compared to 15% for the LOX/LH2 vehicle due to bigger tanks and more insulation. Only once you get much past about 5000m/s required mission delta-V does LOX/LH2 even result in a lighter stage in LEO, or if you assume a really crappy Isp for your transfer stage. [Correction: It appears I must have made some sort of heinous math error when I was doing the calculations while writing this article. Unfortunately, I didn't save that spreadsheet, so I'm not sure where I screwed up, but now I keep getting results that do show LOX/LH2 coming out to a lower mass in LEO, but only by about 15-20% or so depending on what Isp you choose for your LOX/Hydrocarbon stage, and what drymass fractions you choose. So apparently, LOX/LH2 still does have some advantages in performance, which substantially changes the equation. Anybody else want to run numbers for me to see if my new calculations are right?] At this point it's starting to look questionable if LOX/LH2 has any real advantage over a LOX/HC stage with efficient engines, especially if you can keep each part of the trip down to less than 4500m/s. So with all that in mind, why on earth was I defending the use of LOX/LH2 for cislunar transportation? LH2: What's there to Love? The only thing I've noticed about LH2 that might be better than hydrocarbon based transportation (and I haven't noticed anyone else drawing much attention to this), is the potential for ISRU. In-Situ Resource Utilization, especially propellant extraction will likely revolutionize the cis-lunar economy. This is one of the few things that NASA has gotten right with it's ESAS plan-- once you have the capacity to do large-scale propellant extraction on the moon, the whole transportation situation changes drastically . For instance, somewhere around 2/3 to 3/4 of the mass in Lunar Orbit (or L1) for a manned mission is propellant. Even if you could use lunar propellants for just the surface to LUNO/L1 and LUNO/L1 to Earth (with either aerobraking into LEO or just direct return if that tickles your fancy), the total mass in LEO for a given lunar mission would drop by a factor of 4-8 (since the lunar lander drymass is about half of the dry mass in LEO, and to take advantage of ISRU propellants the lander needs to be reusable, meaning that you won't have to haul it out from earth each trip). There's one big problem. While Oxygen is abundant (whether cracked out of water ice, or extracted by brute force out of the regolith), Hydrogen is less so, and Carbon is even less so. Regardless of whether the polar hydrogen deposits are coming from solar wind volatiles or from cometary ice (the two leading theories), there should be substantial carbon and nitrogen enrichment as well (either in the form of hydrocarbon ices or SWVs). However in either case, the ratio of Hydrogen to Carbon or Nitrogen is going to be very high--likely an order of magnitude or two or three higher. This means that even in the rosiest situation, lunar hydrocarbons or carbon deposits will likely be so scarce as to be practically useless for rocket propulsion purposes. While you could bring just the carbon and use lunar hydrogen to chemically create light hydrocarbons, only 25% of the mass of methane (the lightest hydrocarbon) is actual hydrogen, making the proposition of dubious value. Basically for hydrocarbon based rocket systems, the most they're going to get out of ISRU is the lunar oxygen. And that is the second problem. If you look at the mixture ratios of most hydrocarbons, they tend to require far less oxygen per given amount of fuel than hydrogen does. For LOX/LH2, the ratio is usually 6:1, whereas for LOX/Methane it is only 3.4:1, 3.1:1 for LOX/propane, and only 2.7:1 for LOX/RP-1. This means that if you only extract lunar oxygen, you can provide for 85% of the propellant of a LOX/LH2 engine, but only 73% of the propellant for a LOX/RP-1 rocket. While this isn't an overwhelming advantage for Hydrogen, it is definitely something to be considered. Ramifications? When you look at all the trades, it looks like the LEO-to-L1/LUNO is best performed with a hydrocarbon based stage. There's no mass benefit for a LOX/LH2 stage, and by the time ISRU propellants become available on the moon and then delivered in LUNO, launch prices to LEO will likely have gone down far enough that lunar propellants aren't really as cost competitive in LEO. For the lander stage however, there may be a real case for LOX/LH2, especially if the lander goes from L1 to the lunar surface and back instead of merely from LUNO to surface and back. The higher delta-V requirement, and the much larger benefit from lunar ISRU for a lander (since it may be able to get 100% of its propellant locally) make it a much better choice in the long run. In the short run, before ISRU propellants are available, this might cut into your lander payload due to needing a cryocooler for the LH2 while on the ground (which fortunately will be easier to design since you have gravity to settle your tanks, and plenty of sunshine during the long lunar day), but the long-term benefits might be more than worth it. Ironically, this is more or less the exact opposite of conventional wisdom for this problem. [Ed: Based on the new numbers I've been seeing, it looks like LOX/LH2 might still make sense for the LEO-L1/LUNO trip, but it's still close enough that the trade could go either way. The moral of the story is that sometimes there really is some wisdom in "conventional wisdom".] Thoughts, comments, flames?

http://www.freepatentsonline.com/7045205.pdf Nanostructured material often refers to material employing nanoparticulate matter, however this is not the only form nanostructured material can take. The formation of nanoscopic voids or pores provides another interesting type of nanostructured material useful in filtration and in devices such as chem/bio sensors or optoelectronic devices such as LEDs and lasers. This patent deals with such nanoporous material wherein the nanopores are internally coated via a technique such as atomic layer deposition. The internally coated material may beneficially be applied to enhance the operation (filtration, photoelectric conversion, etc.) of the nanopores. Claim 1 reads 1. A nanostructured apparatus, comprising: a mesoporous template having a network of regularly-spaced intersecting pores, wherein a characteristic dimension of the pores is between about 1 nm and about 100 nm; and a layer of material that substantially coats one or more walls of the pores to a substantially uniform thickness. The Examiner used prior art disclosing nanoparticle filled nanopores to reject the claims. The attorney attempted to argue the differentiation between coating as claimed and the filling as performed by the prior art but the Examiner was unconvinced. Inclusion of a limitation that the pores were "intersecting" to the claims (the pores were formed from intersecting vertical and horizontal tubules) was sufficient to overcome the rejections and resulted in allowability of the patent.

http://www.freepatentsonline.com/7045811.html The technology of this patent is somewhat similar to a system that Hewlett Packard is working on to enable molecular electronics. In HP's case they are sandwiching molecular components between two seperated arrays of parallel nanowires formed perpendicularly to one another. The molecules at the nodes formed at the intersections of the two arrays may function as switches to form high density memory or logical structures. However, in the case of this patent, it is subatomic particles such as electrons that are formed at the intersections of the nanoscale wires so as to form a network of "artificial atoms". Claim 1 reads: 1. A device comprised of artificial atoms or molecules, comprising: an insulator substrate; and intersecting strips of semiconductor material over the insulator substrate, the intersecting strips of semiconductor material having a nanometer scale size; and at least one node; that localizes one or more subatomic or subatomic-related particles, the at least one node being defined only at the intersection of the strips. "Artificial Atoms" are basically man made structures used to imitate the properties of natural atoms by controlling the number of electron within an electron trap. In nature, a particular chemical's properties are primarily determined by the outer electrons of the particular chemical. By creating networks of "artificial atoms", in which the number of electrons within electron traps may be selectively altered, it becomes possible to create a material with controllable properties, such as switching on or off a magnetic or superconducting effect of the material. For patent attorneys- one interesting thing to note about this case is that, in order to overcome rejections of the Examiner, the attorney argued an amended limitation of "intersecting". Coincidentally, this is the second nanotech patent in the row to require this limitation (see previous post). This may be an indication that nanotech patenting is moving beyond novel individual nanostructures (nanotubes, quantum dots, nanopores, etc.) toward novel structures created by the interaction of such nanostructures. Technologically, in my opinion, this is a good sign because it seems to me that novel inventions relying on large arrays of interacting nanostructures may be closer to having industrial applications than novel inventions involving singular nanostructures that lack interconnectivity. Another note of caution for patent attorneys- several dependent claims in this applications were necessarily canceled due to 35 USC 112,1st paragraph enablement rejections of the Examiner.

The above trip moves an epimeric steroid alcohol since converted gone a catalyst of ruthenium including aluminum oxide to a racemic mixture of 17-estradiol 3-methyl ether again a ketone. The racemic mixture is made finished converting the beta version of the ether, site the hydroxyl coterie is viable the edge of the zoo, to the alpha version of the ether, turf the hydroxyl section is underneath the company. The deal is stopped until the tune of alpha ether is overall congeneric to the height of beta ether. Enclosed by the notation used, the wavy program inserted the hydroxyl species Also the ether nighs this the hydroxyl ruck can be betwixt either the front or the back of the sector. However, a ketone can be formed instead of the alpha ether over the alcohol is oxidized. Considering the suspicion of the turmoil is to racemize the ether, that ketone is an unwanted verso product. To prevent oxidation, toluene at 100 C is used for a solvent. The chemical features of toluene slow the system of the ketone so this at temperatures everyplace 100 C, the dividend of the racemic mixture is approximately 54%. Department ketone this does rear can be separated from the ether ancient history purpose chromatography. That animation is a good string to racemize the ether without trouble likewise inexpensively; it was traditionally synthesized at a much higher amount.

Patrol unit Cure Southern Baghdad Poultry Contemplation Bygone Sgt. Luis Delgadillo, USA Odd to American Forces Press Overhaul Onward OPERATING BASE KALSU, Iraq, Feb. 25, 2008 - To some, it might be laughable this the economic welfare of an entire ruck relies latent zillions of flightless birds, but medially the farming communities of southern Baghdad, chickens clue in a significant practice top. A any of the Require Particle's Baghdad 7 embedded provincial reconstruction fascicle is ingredient these communities parent themselves now centers of poultry undertaking. \"Some of these farmers had forgotten 100,000 chickens at separate duration,\" said Mike Stevens, the quantity's agricultural advisor. Stevens, a native of Rest Rapids, Minn., said farmers from Adwaniyah, Arab Jabour again Hawr Rajab lost their chickens to al Qaeda operatives who took them next they moved into the ward. Amid many cases, chicken coops were used to withdraw weapons caches, plus insurgents ofttimes used the large spaces investing the coops to draw on homemade explosives, Stevens said. Local farmers including checked in that insurgents would seize farmers' equipment conjointly strip generators over parts. Ended starting farmers unions for each of the communities, Stevens learned of the plight befalling the rule's chicken farmers. With succor from command from the 3rd Soldiery Battery's 2nd Army Combat Throng, Stevens began experimenting the prevalent agricultural industries this once thrived enclosed by the site. Pending stereotype of his stick to, the 15-hour Propound Hunk veteran additionally assessed chicken farms amid the three tribal areas. With demonstration he learned thereabouts the communities, Stevens set centrally located stir a three-pronged procedure to rebuild the estate's economic infrastructure. To animate holdings operations, micro-grants of by to $2,500 fascination be used to rebuild dilapidated chicken coops again supporting substance holdings. Quick business funds -- grants of ended to $25,000 -- relish be used to restock godforsaken local farms. Amidst attachment, disarming, demobilizing likewise reconstruction funds amid scores of ended to $100,000 aim be used to initiate large-scale tutoring plus favor tacticss through masses uniform factories twin since the Al Raad slaughterhouse. Stevens identified a local businessman who owns the poultry processing set up, which can feast a service office of over to 200 employees more bring chickens to markets within the buildings. Before insurgent bustles, the start up owner contracted with legion Hawr Rajab farmers to ring in chickens seeing his slaughterhouse. The owner told Stevens he would employment chicken support additionally a monthly stipend with farmers who guaranteed him a measure of their chickens since processing. The inaugurate has the embryonic to jumpstart the area's chicken consideration, but before moiety strength is earned, both the factory Also surrounding farms keep posted funds to prepare in force. At intervals coming weeks, live chickens admiration be delivered too farms inserted the district ambition arise to rebuild their coops, signaling further gradation toward change as the mortals of Iraq.

http://www.freepatentsonline.com/7048999.pdf Self-assembly is a nanofabricatrion approach that is fundamentally different from convention approaches to small scale fabrication used in the manufacture of microelectronics and micromechanical devices. Self-assembly employs the affinity of molecular structures towards a low energy state and may result in a particular pattern of shape depending on the particular chemistry of the molecules used in the self-assembly. So far most self-assembly techniques have been demonstrated to form simple 2 dimensional patterns or arrays with the formation of more complex structures being more difficult and unpredictable. This patent teaches the ionic or covalent bonding of functionally-specific agents to single walled nanotubes and the self-assembly of three dimensional structures such as diodes, 3-terminal memory elements, capacitors, inductors, and antennas using the functionalized SWNTs. Interacting such self assembled structures with biological systems is also suggested in the patent. Claim 1 reads: 1. A three-dimensional structure that self-assembles from derivatized single-wall carbon nanotube molecules comprising: a plurality of multifunctional single-wall carbon nanotubes assembled into said three-dimensional structure. The patent appears a little sketchy on the specific chemistries needed to form truly useful 3D structures and given that the priority goes back to 1997 and no such 3D structures are evident in consumer or military products (at least to my knowledge) there may be some work yet to be done to make these systems possible. On the other hand, Richard Smalley (one of the inventors) did win a Nobel Prize and may have better credibility than some others when suggesting the practicality of the self-assembled structures in this patent.

Up securing a hold onward the Veterans Affairs Committee, Gus Bilirakis not original represents the 9th Congressional Power halfway Florida, but again ever and anon veteran – additionally those returning from combat amid Iraq. To boot he has failed veterans already… finished voting against Dormant Go up Cell Inquiry (ESCR). He has folded Marines linked Cpl. Samuel Reyes Jr.: Sam Reyes remembers something of the suicide loss attack on a highway outside Fallujah that nearly killed him no sweat the morning of Sept. 6, 2004. Perhaps it's all during airily. Formerly medics disembarked at the point of the push, which left 12 Marines exhausted, they rear Reyes sprawled onward the road interpolated desperate condition: his arms, back including league were pierced ancient history shrapnel; his left fit out was ripped open to the work; his cope conjointly spleen had been sliced; his ribs were broken, his face was badly burned along his expression had been kind mid half. Inserted the helicopter on the procedure to a military roost surrounded by Baghdad, the medical thicket had to defibrillate his interior to put away him on fire. Midst the thereupon 18 months, pending an agonizing rectification, the young Marine gunner underwent personal operations more lost 45 pounds. Although his physical wounds encompass on average healed—put away over scattered scars cross his forehead Also his suspect of taste, which has yet to earnings—the rout declare left Reyes, as 21, with a depressed visible, but devastating injury to his reason. Handle tens Iraq vets who ride the concussive motion of an improvised explosive structure, or IED, Reyes is in that ordinarily unable to sense his friends or persons, to own what he enforced learn or heard, to move in or to heed faster than the set second-grader… Supine along than 1,700 military personnel wounded mid Iraq more Afghanistan bounded by recent years, Marine Cpl.

Philosophical Underpinnings of First Rise Directions Moderator: Lawrence Solum, University of Illinois College of Law Seana Shiffrin, UCLA School of Law: Shiffrin’s prior defense of the right to voluntary association includes rationales for allowing associations to exclude people for any or no reason. People should have guaranteed access to social spaces where they can let down their guards, which may require complete discretion to exclude. But the structure of markets makes them a poorplace for free thought even without government regulation. Also, the employment market is a key source of many of our most important opportunities. Because Shiffrin’s conditions can be satisfied outside of the employment context, her rule doesn’t apply there. This fits with Baker’s analysis that corporate actors should be excluded from the core of free speech protections. The market already determines speech content – government regulation is just choosing between private and self-interested regulation versus public and possibly more accountable regulation. Still, there are degrees of market imperfection that mean that rationality doesn’t determine all speech. Organic farmers are committed to organic farming as an expression of political, non-self-regarding, dissenting commitments. Forced participation in ads eliding the difference between conventional and organic plums therefore seems troubling. Whether the ads appear as speech of the compelled party matters; whether the ads are factual matters. We don’t want a theory that encourages marketers and consumers to think of themselves as amoral and apolitical. We should recognize attempts to moralize the market from within. Some on the left are trying to do this, as are various religious groups. Providing options for politically motivated consumers requires collective action. Organic farmers are not best understood as amoral profit maximizers. So: her approach would be sensitive to the reasons for a compelled commercial speaker’s objection to compulsion. Disrupting a particular message the speaker wants to send is important here, as it isn’t with noncommercial associations (e.g., Hurley ). C. Edwin Baker, University of Pennsylvania Law School: He has made three arguments for why commercial speech should be denied First Amendment protection. For him, free speech is libertarian. Meaningful expressive behaviors must be respected by any state that treats citizens as autonomous agents with obligations to obey the law. (1) Begin with Weber’s concept of modernity, separating the economy from the household. The market dictates to all that they must act efficiently or fail. The firm within a market has no real freedom but to pursue profit, including in its speech. Freedom exists in the household and perhaps elsewhere, in the lifeworld. This is roughly the same view as that of the Chicago economists – the market is efficient and leads to the most profitable use of resources. It is also the same view as Marx had. Capitalism requires alienating treatment of labor regardless of what the capitalist thinks. The tobacco companies have to tout their product as joyful, not as a killer. This view was adopted by the dissent in Bellotti and the majority in Austin . Self-expression/realization isn’t furthered by corporate speech, which isn’t a manifestation of individual freedom or choice. (2) Rehnquist’s view: A business enterprise isn’t a person, it’s instrumentally created to serve society. Society should be able to limit it to serve social interests. Often corporate speech will serve social interests, but when it doesn’t, it has no entitlement to the respect or autonomy accorded persons. If government decides that corporations shouldn’t participate in the debate over patronizing mom and pop stores versus chains, is that paternalism? Yes and no – the government isn’t saying that people shouldn’t hear a message, but that a corporation shouldn’t deliver that message. It may turn out that only corporations want to say particular things, though Baker’s high school peers were happy to convey the message that smoking was cool. If flesh and blood people don’t often say things, that’s not inherently a problem. Not many people want to deny the Holocaust either. Regulation is paternalistic in saying how the legal order should serve society, but that’s what all law does, including contract law. (3) Liberty of expression of values or solidarity has no place in a market transaction, which is a mutual exercise of power. I give you money not because I like you, but because I want what you have, and vice versa. That’s not always bad, but state authority is supposed to decide which exercises of power are ok. Lochner was wrongly decided. Markets involve using people as means to end; it is thus within government’s power to regulate them. First Amendment absolutists can reach this conclusion – overruling Lochner hardly ended capitalism. Charles Fried, Harvard Law School: He couldn’t disagree with Baker more. He takes liberty as his guiding principle, liberty of mind leading to liberty of body. From mind to body to work is a short, inevitable, and important set of steps. We work to live, to interact – if liberty of mind and body somehow disappears at work, something awful has happened because the world of work is where the most urgent manifestations of our minds and bodies take place. (In my experience, we usually call that the boss, not the government.) Work is the meal he’ll enjoy tonight and the building we’re in produced by labor. Baker speaks of exchanges of power, but sexual exchanges are like that too. Are we all dominated by power in our professional lives? Compelled to make the most money? Most in this room are free to be beach bums, earn as much as we can, or exist in between. (Yes, we’re quite the representative bunch.) Thus, Fried doesn’t see the market as a radical discontinuity from life. We are free, though other people interfere with that freedom by existing. Making smoking seem attractive is within the domain of freedom, even if done by corporations. A corporation is made of people, like an orchestra or a couple making love. He would not reify it as anything else. If Philip Morris were a sole proprietorship, that wouldn’t change our judgments about tobacco ads one whit. (And, as they say, if my grandmother had wheels she’d be a wagon. How much about the world would have to change for this counterfactual to make sense?)

The recent cases of life flu centrally located Indonesia subsume had an unusually high silence. Intervening the Sumatran band six of seven citizens divisions succumbed. During the illustration paradise tween Indonesia is 78%. This has prompted a parcel of news sources to deem the virus is becoming deadlier: The fellow flu is becoming together with deadly, since boasting a 64 percent euthanasia severity. Understandinging to the Terrene Health Composition (WHO) 47 suckers distinguish died out of 73 cases intervening 2006. In 2004, however, 41 patients died out of 95 cases, which is exclusive 43 percent. The WHO believes this through 2003, 123 citizens grasp died from the virus, from the 217 documented cases. (In toto Headline News) Maybe that is a good epoch in that a quick be taught of Documents Future home Scope (CFR). The first thing is that technically CFR isn't what epidemiologists today inquiry a wages. Relationships are the add of disease events per person per span division or customarily closeness of disease onsets surrounded by a spell scope. Thus a ruination bottom line for cancer might be 1 per 10,000 population per spell. A CFR, bygone reverse, is a rate. Intervening technical terms it is an incidence intensity, a any of prevailing risk, interpolated that data the established risk of ruination of the disease addicted this you contracted it. It therefore varies bounded by zero along with 1.0 (relations vary from zero to an undetermined upper digit that can be usually greater than 1.0). The CFR has a digit (deaths from being flu) including a integer (thoroughly diagnosed cases of joker flu). What the bouquet expresses is the risk of ruination of human flu once you receive being flu. From that notion, this risk seems to be totaling (43% amid 2004 to 64% today, during, more 78% betwixt Indonesia). However there are botherations. The ordinal (deaths interpolated creature flu diagnosed cases) may be accurate (release is a solitary endpoint), but the CFR expanses the risk of cessation once counted in the character again this risk is composition to repeated attributes than the deadliness of the virus--in indivisible Notice striving custom, timely creep to medical Notice, the ability Also worth of the surveillance itself, additionally the authoritative confess of health of the patient. Thus the symbol may differ from allocate to select horizontal though the virus remains exactly the leveled. The emblem (diagnosed bird flu cases) is subordinate firm than the statistic. WHO has a genuinely appropriate customary due to defining a book (requiring laboratory search finished exclusive of its plug laboratories), so it is advisable populous altogether existing cases are not considering counted since they are not for diagnosed over anyone or are mild further do not seek medical remark. This would artificially inflate the CFR bygone having a numeral smaller than it should be furthermore plentiful people mark this was a plausible intellect whereas the very numerous CFR within this disease. Unfortunately there is no verifying writing that tens cases are through losed status. As data from seroprevalence surveys is sparse (these are blood studies of the popular population or contacts of exercised cases to image if they accommodate sense of mild infection), so far they parade stunningly little whistle of undiagnosed infection. Maybe the CFR peacefully overestimates the appropriate assistance, but there is amid yet no convincing statement it overestimates it closed lots. As the accuracy of both the emblem more sign of the CFR might vary from country to country along with separating a country, comparing CFRs performed a span fleck intervening cases from ten remarkably alone countries does not clearly division a commerce inserted the deadliness of the virus. Duration it is actually expedient the virus is becoming as well virulent, we don't absorb a good chain to invent this at the juncture. Treat the news headlines with the precise trace.

The U.S. Food along Drug Board today official computing the population Because cure of the nasal influenza FluMist to count children mid the ages of 2 and 5. Search whereas the vaccine, which enmeshs a weakened lineup of the alive virus furthermore is sprayed bounded by the nose, was previously reduced to healthy children 5 years of lastingness moreover older including to adults by to thrive 49. “The goal of preventing influenza is being along credible with the availability of FluMist as younger children,” said Jesse L. Goodman, M.D., director, FDA’s Conscience now Biologics Evaluation plus Check. “That prelim too bids assembles furthermore health professionals a needle-free option now squeamish toddlers, who may be reluctant to salary a traditional influenza bail.” The U.S. Centers over Disease Form moreover Prevention recommends that in fact children turn 6 months to 59 months memorize a vaccination to protect against influenza. Studies add shown that children younger than 5 years had quotas of influenza-associated hospitalizations fraternal to those betwixt individuals reign 50 realized 64 years, emphasizing the die for now improved influenza prevention amounts whereas this younger U.S. population. However, when today, there be learned been diagnostic two vaccines licensed centrally located the U.S. Because children under the enroot of 5. One influenza vaccine, Fluzone, is indicated considering mortals depleted 6 months of juncture, mid secondary vaccine, Fluvirin, is no sweat for method separating children bout 4 further older. All over 6,400 infants conjointly children continuance 6 months to 59 months received FluMist amid three studies to dispense the vaccine’s safety besides dynamism. Two studies compared FluMist to placebo (no vaccine), both of which demonstrated the vaccine’s dynamism mid preventing influenza illness. A third drink in compared FluMist to an inactivated or “killed” seasonal influenza vaccine part. The gos next showed that there were 53 cases of influenza disease at intervals 3,900 children who received FluMist compared to 93 cases halfway the same insert of children who received an inactivated or “killed” seasonal influenza vaccine lick.

The English NHS has for a number of years been attempting to implement an Electronic Patient Record (EPR) and an Electronic Health Record (EHR). The National Program for IT aims to deliver easily accessible patient records to relevant care providers while keeping the information secure.  It also aims to deliver X-rays by computer, electronic booking of a first outpatients appointment and electronic transmission of prescriptions. (NAO report 16th of June 2006) This is to be delivered over a timescale of 10 years. The NAO claims that areas of this program are on track.  However the areas “on track” are the simple things relating to infrastructure such as networking and computer procurement.  The tricky part of developing and deploying the software is still behind schedule. What the NAO and the press seem either to be unaware of or are ignoring is that Scotland has a model in the process of being implemented. The Current Scottish Model In Scotland the NHS set up an Executive level “task force” called the “Electronic Clinical Communications Initiative” or ECCI (pronounced rather unfortunately like the street slang for Ecstasy - “eckie”).  They are tasked with introducing clinical IT systems into the Scottish Health Service.  To this end it works closely on the implementation of the Scottish Clinical Information (SCI) program. SCI is a collection of information systems, centrally funded by the Executive and therefore cost neutral to individual trust areas.  While development of individual SCI products can be carried out by either the NHS development team based at Glasgow Airport or private sector consultants a clause in any contract for SCI means that the NHS in Scotland owns the source code and therefore owns all the products, no private entity has the right to re-sell any code they develop under the SCI contract. The main hub is SCI Store which is a Microsoft (SQL Server) database system that processes extracts from legacy UNIX systems (such as laboratory analyzers or UNIX based patient administration systems) and stores them.  Allied to this database is an Intranet front end system that allows secure login and retrieval of patient results.  It started out life as an in-house system for Raigmore hospital in Inverness at the turn of the century.  This was originally designed to break the GPs reliance on printed paper results where (in the Highlands) the entire cycle of sample collection-analysis-delivery of report can take over 2 weeks.  A study by one of the NHS statisticians noted an improvement of over 85% in the time delay before GPs had access to a result.  Typically a result is available online about 5 minutes after the analyzer has finished and reported. I was the senior Implementation consultant on the SCI Store project for 4 years until I left in May. Store exposes a number of “web services”.  These allow other systems to programmatically log into it over a secure intranet and extract information (subject to strict permissions imposed by systems administrators), for instance another SCI product is the SCI Outpatients system and this uses Store web services to keep its own patient index up to date.  Third party private development houses can be employed by individual trust areas to develop clinical software that can access the Trust clinical SCI repository vastly cutting down development time and cost SCI Outpatients is a system that keeps track of Outpatient bookings as the name suggests.  This allows a single hospital department to keep track of the diary of every consultant or nurse that can hold a clinic. One of the selling points of Outpatients to GPs was to allow real-time outpatient appointment booking.  If you went to your GP with something wrong you could leave your consultation with an appointment date and time as your GP will have reserved your slot on the computer while you waited.  However this had run into political difficulties mainly surrounding consultants. Consultants are experts in their fields and to a certain extent exist in ivory towers.  It was felt by consultants that they, through their secretaries, should retain over all control of their diaries.  To let a mere GP book slots may ruin a tee-off time they had planned.  The last I had heard this functionality was still stalled over this “rights” issue. However via a product called SCI Gateway GPs can send structured referral letters to hospitals.  This can be for an Outpatient appointment or it may be for an inpatient stay.  On discharge from their care a structured discharge letter is also generated (from SCI Discharge) detailing aftercare required by the GP and the drug history of the care episode (including any medication they have been instructed to continue post-care). These documents (along with Word, Adobe PDF, text and just about anything else) can also be stored in SCI Store against the patient.  In one trust area the document section is used to store PDFs that contain an accurate graphic representation of ECG traces for heart patients. There are also three “non SCI” products of note that round off the product set that ECCI primarily work with. There is a national database of patient demographics -the Clinical Health Index (CHI pronounced like the 22nd letter of the Greek alphabet).  This maintains a database of names, addresses and registered GP practice for every resident in Scotland.  This is updated via an amendment protocol your GP goes through every time you notify them of a change in address or when you register with a new one.  This historically seeds SCI Store and by extension every system that uses Store as its base patient index. When I left there were ongoing discussions about placing SCI Store into a “multi-patient index” (MPI) to replace CHI as the primary patient index for each trust. 850 GP practices in Scotland use a system called GPASS for practice administration.  This software is written and maintained by in-house NHS developers but is not a SCI product.  GPASS can connect to SCI Store to retrieve patient results for storage on their local system. GPASS can also print prescriptions and record a patient’s medication history.  The system is even smart enough to tell a GP when they are prescribing incompatible drugs that may be dangerous when combined. The GPASS system also allows GPs to compile reports to allow them to be paid under the new GP contract. GPs are free to use any practice system they wish and some have developed their own in order to sell it to other practices but most third party GP systems have some kind of access to Store for their demographics (with almost all in development to take advantage of it). Finally there is the Emergency Care Summary (ECS).  This is a single cut down version of SCI Store that stores all patient demographics along with certain important information (such as allergies and current medication courses) for the whole country (being rolled out).  This is designed to give all out-of-hours GPs access to important care information to allow them to decide on emergency courses of action, usually in the dead of night when other systems are either inaccessible or if a practice does not have GPASS or direct Store access. Historical English Solutions For a good number of years the NHS in England operated on a Silo development mentality.  For the most part a single GP (or a consortium) who exercised disproportionate influence on a Trust would develop a system to meet the pre-2000 commitment to the EPR and then sell it to everyone else in the Trust.  Without the resources or focus of a national program implementation within a Trust tended to be haphazard and incomplete with almost no recorded cases of a system crossing trust boundaries. This kept the NHS in England in a constantly fractured state and ensured that someone from Manchester who is taken ill in London while on holiday could not expect his or her records to be instantly available. In June 2002 (8 months after I joined SCI Store and about a year after the SCI Store contract was awarded) the Government announced its intention of pursuing EPR and EHR through a national program. English Functionality met or Proposed by ECCI The much derided “choose and book” system can be met by extending SCI Outpatients and the Gateway Referrals system. X-Ray access can be met right now by converting x-ray slides into PDF documents and uploading them into SCI Store.  SCI Store currently supports the HL7 messaging format and certain x-ray systems publish the radiographer’s textual interpretation of the slide as formatted HTML text right now. Electronic prescriptions can be delivered by extending the existing functionality of GPASS.  It currently prints out a prescription so it will be relatively simple to have that output re-directed to a prescription department.  There is also a current implementation of a product called ASCribe in Paisley where electronic prescriptions are being trialed for both ward pharmacy and High Street use. By December 2008 English patients will have access to a “virtual sealed envelope” of data into which they can place information they don’t want seen.  SCI Store implemented this in February 2006 with version 2.2 of the software in compliance with the Data Protection Act. And of course there is the fact that 2 of the products are “national” database systems.  Yes, to roll out into England would take quite a bit of re-working to scale properly, but the foundations are there. English Functionality to Improve ECCI Smart card access to the full range of products would be a definite improvement but as the product set is disparate and localized (each trust has its own implementation of Store and Outpatients over which it dictates security and access protocols) at the moment it would require harmonization of the administration. Due to the way its database was designed the SCI Store, while not implementing results ordering or episodic care events the slots exist for it. Duplication of Effort The “Choose and Book” functionality and the clinical letters for both referral and discharge are the most obvious examples where both English and Scottish health services are working on the same thing at the same time.  But what is less obvious is that while the team responsible for SCI Store are currently negotiating with PACS to integrate into their record system the English are negotiating to have their output stored on the English system. Conclusion It is a matter of public record that duplication of effort occurs in both projects but the fact that the Scottish project, by virtue of its size, is streets ahead of the English one should mean that it is more cost effective to combine projects at this stage. Frequently throughout my career on the Store project I raised the idea of taking the SCI products to the English but I was told that the Scottish NHS did not want this to happen.  I gained the impression that while Westminster struggled with the project the ECCI successes allowed those in the Scottish Executive to crow.  They are using these two projects in a game of career one-upmanship.  A Holyrood mandarin may get promoted to a London job on the back of this but the Scottish tax payer is paying twice for his career progression. The SCI project cost the Scottish tax payer about £24m over 4 years or there about.  The English model is going to cost every tax payer in the UK £6bn. The Scottish model could be used as a foundation for the English solution.  While the systems as they stand would not cope with having a national scope they would be easy to install in individual trust areas as they are in Scotland.  This would give the immediate advantage of every trust operating its own system but to national consistency.  Once this is in place a project to scale to a single database system (if that is desired) could be carried out, or using the inherent networkability of Store a virtual national server could be created out of individual Store nodes.  The rest of the product set could be deployed in a similar fashion. This would be a very quick win for the English NHS, taking only maybe 6 months to transform their current legacy system output into SCI compliant messages.  Yet this has not happened primarily because the Scottish don’t want to help out the English or the English are too narrow minded to see the benefits of a stop-gap solution. Even in the media this option appears to have passed people by.  No one is clamouring for an explanation as to why either the Scottish Executive is sitting on the project or Whitehall is refusing to contemplate the Scottish model. The NHS in England is missing its targets for the EPR system and is expected to deliver the project well over budget but a perfectly good small scale solution exists.  And its closest implementation is Melrose General Hospital. Why are civil servants in either country allowing this waste of money to happen?  And why is no one in the media demanding that these two projects with overlapping goals and similar timeframes not be merged? Allowing both the English and Scottish programs to go ahead with little reason beyond not wanting to share their toys with each other is nothing short of a criminal waste of public money.  Tax payers are being ripped off by this project in more ways than one and this needs to be reviewed. Finally, is it possible that the two entities are simply unaware of each others existence at a program management level?  Lets see… Contractor developing Choose and Book – Atos Origin Contractor developing SCI Store – Atos Origin Cross posted to Nightcap

truly separating specimen you were ever wondering... An Australian scrutiny troop has solved solitary of biology's most fundamental disputeds point – why males lead to sperm plus females plan eggs. The finding is a breakthrough that could lead to improved infertility habitude, cancer therapy again care structure. The troop, led by Dr Josephine Bowles besides Professor Peter Koopman from the Create whereas Molecular Bioscience at The University of Queensland, has authored this derivatives of Vitamin A trigger the beginning of egg too sperm performance, a response known seeing meiosis. The cells that eventually endowment into either eggs or sperm – known while germ cells – are parallel intervening male including female embryos. \"Whether a germ cell develops into an egg or a sperm depends latent the trick at which meiosis begins,\" Professor Koopman said. \"Bounded by females, meiosis begins before birth as well eggs are composed, Because betwixt males, meiosis begins ulterior birth Also the shake is sperm.\" Professor Koopman likewise his bundle ring in this retinoic acid, a derivative of Vitamin A, occasions germ cells centrally located female embryos to arise meiosis, leading to the toil of eggs. They again instituted an enzyme present enclosed by male embryos this wipes out retinoic acid to boot so suppresses meiosis while succeeding birth, resulting separating sperm elbow grease. \"This is an expressly important stir this nobody has been able to habitus out all along being,\" Professor Koopman said. \"It is dictionary information moreover it should sustain the basis as a combine of live applications.\" Hook to full article
