    1990-01-01

    Batch-mixing experiments to evaluate postmining water quality at the Cordero Mine were conducted by the US Geological Survey during 1984 to 1985. Contact of groundwater from the spoil aquifer with fresh spoil material caused only small changes in major-element concentrations and in pH, unless sulfide oxidation or contact with soluble salts, such as epsomite, occurred. In contrast, large changes in major-element concentration resulted when water from the coal aquifer contacted the spoil material. Only three of seven reaction models considered to explain the water quality changes during the batch-mixing experiments were consistent with the thermodynamic and mineralogical data. The three models used to account for the observed water quality changes derived potassium from potassium feldspar; magnesium from chlorite or epsomite or both; sodium from cation exchange and halite; chloride from halite; silica from potassium feldspar and chlorite; sulfate from gypsum, or epsomite or both, and carbon from carbon dioxide. In general, water quality samples obtained from the batch-mixing experiments using water from the coal aquifer had smaller major-ion concentrations than the actual water quality in the spoil aquifer. These differences can be explained by the limited amount of efflorescent salt dissolution and volume of water used in the experiments. Correction ratios calculated for these experiments may be applied to batch-mixing experiments at other mines in the area, to predict postmining water quality. 26 refs., 21 figs., 14 tabs.

    Anterior tooth fracture as a result of traumatic injuries, is frequently encountered in endodontic practice. Proper reconstruction of extensively damaged teeth can be achieved through the fragment reattachment procedure known as “biological restoration.” This case report refers to the esthetics and functional recovery of extensively damaged maxillary central incisor through the preparation and adhesive cementation of “biological post” in a young patient. Biological post obtained through extracted teeth from another individual–represent a low-cost option and alternative technique for the morphofunctional recovery of extensively damaged anterior teeth.

    New clamp for optical posts reduces time required to set up optical components. Joins pair of perpendicular posts supporting laser, lens, reflector, or other optical component and enables posts to be rotated in perpendicular planes so orientation and position of component adjusted. Advantage of clamp conferred by its E-type retaining rings, which hold post-clamp collars to post-clamp body. Collar tightens around post to prevent movement along post while allowing clamp to turn around post. Quarter-turn screws on body and collars tighten parts on post. Does not tend to mar post.

    Quantum posts are assembled by epitaxial growth of closely spaced quantum dot layers, modulating the composition of a semiconductor alloy, typically InGaAs. In contrast with most self-assembled nanostructures, the height of quantum posts can be controlled with nanometer precision, up to a maximum value limited by the accumulated stress due to the lattice mismatch. Here, we present a strain compensation technique based on the controlled incorporation of phosphorous, which substantially increases the maximum attainable quantum post height. The luminescence from the resulting nanostructures presents giant linear polarization anisotropy.

    2004-06-01

    Although acne has traditionally been viewed as predominantly affecting adolescents, a significant and growing body of literature suggests an adult (i.e. post-adolescent) form of the disease. This review summarizes selected publications on post-adolescent acne, and discusses possible causes and treatment options. Recent epidemiological studies show that there appears to be an increase in post-adolescent acne, and that the disease is lasting longer and is requiring treatment well into the mid forties. There is good agreement that, unlike teenage acne, where males tend to show the most severe forms of the disease, post-adolescent acne mainly affects females (the lesions are frequently perioral and occur premenstrually) and that there are two forms of the disease. The terms 'persistent' and 'late onset' are now generally accepted as describing these two types. The causes of post-adolescent acne remain to be fully elucidated and hormones, colonization by resistant bacteria and the use of cosmetics have been put forward and debated in the literature. Additionally, some clues to the cause of post-adolescent acne may be gleaned from an individual's response to therapy. Perhaps one of the most intriguing explanations for the increase in this disease is the proposed relationship between increasing stress levels, androgen hormones and increasing levels of acne found in women in fast paced jobs.

    Traceability programs can cover the whole of life, or parts of it, for individual animals or groups/lots of animals. Of 13 country or community traceability programs for cattle/beef, 11 are mandatory (4 encompass, or are scheduled to encompass, birth to retail; 7 cover birth to slaughter) while 2 are voluntary and encompass birth to slaughter. Of 10 country or community traceability programs for swine/pork, 2 are mandatory (1 covers birth to retail; 1 covers birth to slaughter) while 8 are voluntary. Of 6 country or community traceability programs for sheep/sheep-meat, 3 are mandatory (1 encompasses birth to retail; 2 encompass birth to slaughter) while 3 are voluntary. Mandatory birth to retail programs that include "post-slaughter individual animal identification (IAID) traceability" have been implemented for cattle/beef, swine/pork and sheep/sheep-meat by the European Union and for cattle/beef by Japan. Many of the voluntary as well as mandatory, birth to slaughter traceability programs for all three species are presumed (though that is not specified) to include "post-slaughter group/lot identification (GLID) traceability" - e.g., those qualifying products for shipment to the European Union. "Post-slaughter IAID traceability" can be accomplished in very-small, small, medium, large and very-large packing plants using single-carcass processing units, tagging and separation/segregation, and/or deoxyribonucleic acid (DNA) fingerprinting technology but all of these approaches are time-consuming and costly; and, to-date, in most countries, there has been no reason compelling enough to cause industry to adopt such protocols or technology.

    2015-01-01

    Chronic pain, especially headache, is an exceedingly common complication of traumatic brain injury (TBI). In fact, paradoxically, the milder the TBI, the more likely one is to develop headaches. The environment of injury and the associated comorbidities can have a significant impact on the frequency and severity of headaches and commonly serve to direct management of the headaches. Trauma likely contributes to the development of headaches via alterations in neuronal signaling, inflammation, and musculoskeletal changes. The clinical picture of the patient with post-traumatic headaches is often that of a mixed headache disorder with features of tension-type headaches as well as migrainous headaches. Treatment of these headaches is thus often guided by the predominant characteristics of the headaches and can include pharmacologic and nonpharmacologic strategies. Pharmacologic therapies include both abortive and prophylactic agents with prophylaxis targeting comorbidities, primarily impaired sleep. Nonpharmacologic interventions for post-traumatic headaches include thermal and physical modalities as well as cognitive behavioral approaches. As with many postconcussive symptoms, headaches can lessen with time but in up to 25% of patients, chronic headaches are long-term residua. PMID:25701908

  16. Post-mortem toxicology.

    PubMed

    Drummer, Olaf H

    2007-01-17

    Studies examining post-mortem processes are difficult to conduct since changes will have already occurred when the body arrives at the mortuary. While control of collection site for blood can minimize changes in concentration it is very difficult to conduct experiments in humans aimed at understanding the mechanisms and determining the extent of such changes. The use of appropriate animal models can be useful in this regard providing the species and conditions are carefully chosen. Pharmacokinetic studies in humans are also very useful for understanding the changes in drug concentration with time in blood (and other fluids) and also for improving our understanding of drug effects. Unfortunately, doses of illicit drugs that can be given are relatively low to guarantee safety hence extrapolations are made to real life situations. Individual case studies can be useful to describe an unusual or particularly interesting circumstances but little useful information can be obtained when trying to ascertain the role of competing factors, e.g. role of individual drugs when multiple drugs are present, varying toxicity between route of administration, and the role of age or natural disease when drugs are also present. Epidemiological approaches by reviewing large numbers of related cases are the most powerful tool to obtain this information. All of these studies need to operate under the ethical and legal framework appropriate for a jurisdiction. This paper discusses the relative merits of scientific approaches to research in post-mortem toxicology and provides guidance on the most appropriate techniques for future studies. PMID:16781104

    Post-traumatic endophthalmitis is a rare but serious complication of open globe injury, representing a major turning point for the patient's visual prognosis. Risk factors for this complication are lens capsule rupture, an intraocular foreign body, type of eye trauma and especially a delay in initial management of the trauma. Although Staphylococcus epidermidis is the most common organism, as in postoperative acute endophthalmitis, other microorganisms are more frequently represented and the multi-microbial involvement is common. The diagnosis can be difficult in the presence of inflammatory signs of trauma. Aside from rapid globe repair, neither preventive nor curative treatment have been well delineated. The class of antibiotics, the dosage, route of administration, as well as surgical treatment by vitrectomy remain topics of discussion. PMID:26563842

    Varicella zoster vasculopathy is a rare complication of chicken pox. Varicella cerebellitis, a post or para-infectious condition, is a common sequelae of chicken pox. Varicella angiopathy presents as acute hemiparesis, aphasia, hemianaesthesia or other focal neurologic or retinal deficits associated with mononuclear pleocytosis and VZV specific antibodies in CSF. Varicella angiopathy affecting the posterior circulation is very rare. We report a 15 yr old boy with progressive neurologic deficits over a month following a chicken pox 3 months prior to the onset of symptoms. On investigation he had infarcts both in the anterior and posterior circulation territories in CT and MRI with mononuclear pleocytosis in CSF elevated IgG and IgM in CSF. He was treated with intravenous acyclovir and corticosteroids. PMID:21391380

    As clinicians we continue to search for a post system which will give us maximum retention while maximizing resistance to root fracture. The introduction of several new post systems, with claims of high retentive and resistance to root fracture values, require that independent studies be performed to evaluate these claims. This study tested the tensile and shear dislodgment forces of four post designs that were luted into roots 10 mm apical of the CEJ. The Para Post Plus (P1) is a parallel-sided, passive design; the Para Post XT (P2) is a combination active/passive design; the Flexi-Post (F1) and the Flexi-Flange (F2) are active post designs. All systems tested were stainless steel. This study compared the test results of the four post designs for tensile and shear dislodgment. All mounted samples were loaded in tension until failure occurred. The tensile load was applied parallel to the long axis of the root, while the shear load was applied at 450 to the long axis of the root. The Flexi-Post (F1) was significantly different from the other three in the tensile test, however, the Para Post XT (P2) was significantly different to the other three in the shear test and had a better probability for survival in the Kaplan-Meier survival function test. Based on the results of this study, our recommendation is for the Para Post XT (P2). PMID:11203854

    (post16) Faces of Physics To study a physics course post-16 is take out an option on your future. But physics itself is very varied, and so is what you might do with it. It seems right that post-16 physics courses reflect important aspects of this variety. Physics varies with why people do it. As reliable knowledge, physics is often essential to making things happen. This is physics as feeding into technology, and quite often feeding off technology. The human urge here is the urge to create things that work. It drives individual inventors; it drives large teams in multinational companies. At the opposite end of this spectrum is physics driven by curiosity, by the urge to find out. The stock examples are the grand discoveries from the expansion of the universe to the discovery of the nucleus of atoms. But the physicist's curiosity is often on a more detailed, even finicky scale: how exactly do the molecules of this polymer respond to stress?; just how do ions implanted in this material modify its conductivity? It is clear to me that a decent post-16 physics course must respect and reflect both. This is by no means a matter of `basic laws and their applications'. It is a matter of recognizing two fundamental interests, in doing and in explaining, and of recognizing that they are at once closely interdependent and worlds apart. Ideas in physics are also not of one kind. One opposition is the idea of describing Nature in terms of deterministic physical laws, as against describing Nature as the predictable outcome of probabilistic behaviour `underneath'. The first has gripped the Western imagination since at least the time of Descartes. The second has increasingly come to the fore, especially in thermodynamics with the idea that we can only make processes work by fixing the circumstances so that uncaring atoms and molecules happen by chance to do what we want. Now in quantum theory both ideas - determinism and randomness - co-exist. Post-16 physics courses are not in danger of ignoring the first, but they are in danger of not recognizing the importance of the second. The great message of regularity from chaos is spoken, if at all, in muffled tones. Bending rays or curving wavefronts? When I learned optics at A-level I remember wondering why the equations of optics had to relate reciprocals of distances. Was this perversity for the benefit of examiners, whose questions taxed my ability to manipulate fractions and reciprocals? - yes, students had mathematical difficulties even then! When I started to teach physics, it was here that I often made mistakes as I tried to show students how to play this game. It seemed that optics was a branch of geometrical drawing. It boiled down to two and a half rules: (1) a ray through the centre of the lens goes straight on; (2) a ray parallel to the axis goes through the focal point, and also vice versa. Students asked (as had I) how a ray parallel to the optic axis knew what to do if the lens was not wide enough to catch it. They wondered why images not able to be caught on a screen were punished by being given negative distances. Only much later did anyone show me that this could all make better sense. Diverging wavefronts of light arriving at a lens had a curvature C before, numerically large if the source was close, smaller if far away. The lens added to that curvature a fixed amount equal to its power P in dioptre. The result was a new wavefront curvature C after given by C after = C before + P which translated into 1/v = 1/u + 1/f. Those reciprocals were curvatures. The lens equation became about what a lens does to light, not about constraints on the paired values of u and v. The minus signs of the Cartesian convention, with lens power being the difference between curvatures after and before, had a reason. The result is not that optics gets easier. The result is that the questions it suggests to the student become more sensible. `Why does a lens add a fixed curvature, no matter the curvature of the incident wave?' `Why does a lens keep the wavefronts spherical?' And the answers draw on physics and glass-shaping, not on rules and conventions. Jon Ogborn

    Post-16 Initiative logo This is the first of a regular series of contributions from the Institute's Post-16 Initiative. The Initiative is taking a hard and searching look at the physics taught in schools and colleges from age 16 to age 19. To start with, it is responding to Government initiatives, but hopes to encourage and stimulate good practice in physics teaching on a longer time scale than can be afforded in making responses to current developments. Here Jon Ogborn writes about what AS courses need to be, while Peter Campbell gives his thoughts about teaching matter. Advanced Subsidiary physics: what should it be? From September 2000 all A-levels will be new. Students can take the first Advanced Subsidiary (AS) year and stop there - or decide to go on. In the Institute of Physics post-16 Initiative, we have been thinking how to provide a satisfying one-year experience of physics at the new AS level, and what it should achieve. The students will decide. So the AS course must give a decent picture of what physics is, what it offers for their futures, what interests it can satisfy. That all says breadth, with enough depth to see what is in store later. And this sounds like the right recipe for someone who is taking a single AS year of physics to broaden their A-level experience. It must also be attractive. A way forward is shown by the Salters - Horners course, attracting interest through leading from applications. Why does that work? It gives physics a story to tell, into which ideas fit and make sense. Our own new A-level, Advancing Physics, must also have interesting stories to tell, which must in addition build up an honest picture of physics. An example: teach electric circuits through modern sensing devices. Sensor instrumentation is a key activity of physicists, full of new ideas, but also simple. It makes essential use of circuits such as the potential divider. Practical work gets better things to do than checking the equation for resistors in parallel. It requires good use of computers. Other examples: use modern imaging methods to teach information processing and optics; study `designer materials' to reflect both the inventiveness and the curiosity of physicists. Tell stories from fundamental efforts to understand the world: forces and motion, waves and photons, the structure of the Universe, a hint of relativity. The new AS course has to fit QCA criteria, but should also look beyond them to suggest how to shape the future of A-level physics. Jon Ogborn Director, Institute of Physics Post-16 Initiative The study of matter The study of matter is as central to pure physics as it is to technological applications. Currently Advanced GNVQ Science requires much more detailed knowledge of materials than most A-level courses. But in every case, what 16 - 19 year-old students experience is a rather dated study of engineering materials, with an emphasis on mechanical properties. Almost entirely absent is the notion of our new ability to design materials. Recently, new techniques of visualization, modelling the hierarchy of structures inside a material and simulating the resulting changes in properties, have all dramatically changed the nature of materials science. Post-16 physics courses should mention some new classes of materials responsible for major industrial and social changes. For example, let's look at `soft matter' such as polymers, liquid crystals and emulsions. These are the stuff of Nature, which we are only now learning to imitate. The continuing miniaturization of computer chips and sensors is based on functional properties - optical, electrical, thermal or magnetic. If students are to understand and perhaps later to contribute to developments such as these, they deserve a better introduction. Careful thinking needs to go into deciding what a basic course might entail. But what topic could be better suited to coursework in the form of student research? Teaching about matter in an up-to-date way may sound too great a challenge for schools and colleges, if we forget the power of new technologies. We can now enhance student learning using key visualization tools: images of materials, from all types of microscopy; animations to show dynamics as well as structure, sometimes in 3D; `virtual experimentation': models to manipulate, with data as well as image outputs. Universities and research organizations could help by contributing to new collections of these tools, annotated at an appropriate level, in CD-ROM format but also at their own websites.

    The Intravenous Fluid Generation (IVGEN) Experiment was a technology demonstration experiment that purified ISS potable water, mixed it with salt, and transferred it through a sterilizing filter. On-orbit performance was verified as appropriate and two 1.5 l bags of normal saline solution were returned to earth for post-flight testing by a FDA certified laboratory for compliance with United States Pharmacopiea (USP) standards. Salt concentration deviated from required values and an analysis identified probable causes. Current efforts are focused on Total Organic Content (TOC) testing, and shelf life.The Intravenous Fluid Generation (IVGEN) Experiment demonstrated the purification of ISS potable water, the mixing of the purified water with sodium chloride, and sterilization of the solution via membrane filtration. On-orbit performance was monitored where feasible and two 1.5-liter bags of normal saline solution were returned to earth for post-flight testing by a FDA-registered laboratory for compliance with United States Pharmacopeia (USP)standards [1]. Current efforts have been focused on challenge testing with identified [2] impurities (total organic-carbon), and shelf life testing. The challenge testing flowed known concentrations of contaminants through the IVGEN deionizing cartridge and membrane filters to test their effectiveness. One finding was that the filters and DI-resin themselves contribute to the contaminant load during initial startup, suggesting that the first 100 ml of fluid be discarded. Shelf life testing is ongoing and involves periodic testing of stored DI cartridges and membrane filters that are capped and sealed in hermetic packages. The testing is conducted at six month intervals measuring conductivity and endotoxins in the effluent. Currently, the packaging technique has been successfully demonstrated for one year of storage testing. The USP standards specifies that the TOC be conducted at point of generation as opposed to point of consumption. Samples were generated and shipped to an FDA facility however, testing determined that the samples failed the TOC specification with most likely due to leaching from the sample container. Shelf life testing is examining packaging techniques and periodic testing of samples of DI cartridges that are capped and sealed in hermetic packages. Periodic testing of the purified water output will be conducted at six month intervals.

    post16.gif As a teacher of physics it is very easy to become preoccupied with particulars of courses, or topics or even single concepts. Concerned with imminent student audiences and desired learning outcomes, the daily challenge is to summon satisfactory teaching approaches and resources for the job at hand. For the conscientious teacher, assessment outcomes may too often seem a judgment on our own efforts rather than those of our students. From time to time we may step back and think bigger, for example while planning a recruitment event, or while away from work on holiday. We may be successful locally. But why, at a time when books and television documentaries popularizing science have a large following, has physics education been facing declining numbers? Many recognize that physics has an essential contribution to make to the training of science or engineering specialists, but we know that it is also important for the skilled worker, the informed citizen and, in fact, for anyone trying to make sense of the world. So what are the best ways forward for post-16 physics? To make any impact on the bigger picture requires organization, thinking and meeting time among people in diverse roles: teachers and curriculum managers; university lecturers; employers and professional bodies; unitary awarding bodies; regulatory and funding agencies; and even Government. For the past few years, the Institute of Physics post-16 Initiative has created an unrivalled opportunity to address the wider issues. Its Shaping the Future booklets series was designed to stimulate informed discussion and debate, by providing background information and analysis. Taken together, the booklets should help all those concerned with physics education to understand where we are now, and why. Literally dozens of people have contributed to a review and analysis of physics education. Each booklet is a 48-page smorgasbord in A4 landscape format, containing many examples of good practice, basic but sometimes hard-to-come-by information, insightful and occasionally witty comment and illustration. The fifth booklet, published in April this year, rounds off the series so far. For those who have not yet seen them, here are the questions that the booklets have explored: Making Physics Connect (editor: Peter Campbell). How can physics courses connect better with the learner and with other human activities and areas of knowledge? Physics in Mathematical Mood (editor: Simon Carson). How can we teach physics in an appropriately mathematical way, conveying the beauty and power of mathematical reasoning to students? Physics in Vocational Courses (editor: Ken Gadd). In the new National Qualifications Framework, what role should physics play in the `general vocational' and `vocational' pathways? The Study of Matter (editor: Claire Davis). What aspects of a wide and interdisciplinary subject should be included in courses at advanced level, and how can these best be taught? Revitalising Physics Education (editor: Andrew Morris). What can we learn from histories of physics and of education, or from curriculum development projects of the last thirty years? What can be said about teaching and learning physics beyond qualifications, or learned from international developments in physics education? These booklets should find their way into every physics department in the UK. They will be of immediate practical use in schools or colleges, informing teaching while also providing stimulus material for discussion among physics teachers. (The latter would rightly be called in-service training.) Student teachers will find them a good guide covering new terrain. Lecturers at higher education level will gain valuable insight into changes affecting their undergraduate intake. And the physics advisory committee of every Awarding Body will surely want to discuss issues raised in the booklets. The main message overall is that, to meet tomorrow's challenges, the many parties involved in physics education must work together for common goals. In the coming year I hope that the Institute of Physics itself will organize discussion meetings among participants representing a full cross section of interests. The Institute of course already works closely with other associations speaking for science and for science education; inasmuch as they explore issues affecting science education broadly, the booklets may present new opportunities for cooperation. Last but not least, it is important that we influence government bodies regulating and funding education. Copies of the booklets can be downloaded as PDF files from the Web at post16.iop.org/shaping/ or purchased (at £5.50 per title, or £22 for all five titles, including p&p) from Ingrid Ebeyer at the Institute (ingrid.ebeyer@iop.org).

    One of the great delights of general practice is the way we are allowed to share people's lives. Another facet is the humbling experience of having a patient intuitively grasp a concept that you have found difficult to understand. As regular readers of these pages are aware, I am no stranger to emergencies and trauma. Consequently I see and experience critical incident stress at first hand. This gives me some understanding of others' experiences and, I hope, might help me prevent critical incident stress developing into the more severe post-traumatic stress disorder (PTSD) in those under my care. How well I recall that it was only the fall of a marble that prevented me from being conscripted for service in Vietnam.

He was seeing me for something or other when he told me the following story. I was so impressed that I asked him to write it down. It speaks eloquently of the aftermath of war and how mates help each other deal with it. It also reminds us that there continue to be new crops of returned service-men who need our help.

  5. Nuclear Power - Post Fukushima

    The extreme events that led to the prolonged power outage at the Fukushima Daiicchi nuclear plant have highlighted the importance of assuring a means for stable long term cooling of the nuclear fuel and containment following a complete station blackout. Legislative bodies, regulatory agencies and industry are drawing lessons from those events and considering what changes, if any, are needed to nuclear power, post Fukushima. The enhanced safety of a new class of reactor designed by NuScale Power is drawing significant attention in light of the Fukushima events. During normal operation, each NuScale containment is fully immersed in a water-filled stainless steel lined concrete pool that resides underground. The pool, housed in a Seismic Category I building, is large enough to provided 30 days of core and containment cooling without adding water. After 30 days, the decay heat generations coupled with thermal radiation heat transfer is completely adequate to remove core decay heat for an unlimited period of time. These passive power systems can perform their function without requiring an external supply of water of power. An assessment of the NuScale passive systems is being performed through a comprehensive test program that includes the NuScale integral system test facility at Oregon State University

    (Post-16 Initiative) Engineering Physics? Many A-level physics students do not go on to study physics. For them physics is a support subject, either just for fun or just for the grade. Where physics is a lead subject some students go on to study physics but many more go on to study engineering. So can we deliberately give some aspects of an A-level course an engineering flavour? Electromagnetism would seem a good place to start. There is a clear `physics' route into this topic, a microscopic forces and fields view of the situation. But do our students really need to look at it this way? All electromagnetic machines are linked magnetic and electric circuits. The design idea is to link these circuits as closely as possible. The electric circuits must be as good as possible, with a high conductivity. The magnetic circuits must be as good as possible, with high permeance. Conductivity depends on area/length. So does permeance. The goodness of an electromagnetic machine (how good it is at its job, which is linking electric and magnetic circuits) scales as the square of its linear dimensions. That means small electromagnetic machines are harder to make, and so the very smallest nanomotors are electrostatic. None of this is new, but many teachers are uncomfortable with it. We are thinking like physicists. Many of our students are not. They deserve us to take the trouble every now and again to encourage them to think a bit differently about a topic, to look at practical ways of discussing design and to give their course an engineering flavour. Philip Britton Coursework in A-level Physics The criteria for the new AS and A-levels have provided the teams developing the specifications with an opportunity to think creatively about how internal assessment is used within post-16 physics courses. Teachers may be concerned that allowing 30% of the marks to be internally assessed will create a burden for them. However, it is possible to look at this in a much more positive light. Provided the tasks are well defined and the marking criteria are straightforward to apply, internally assessed work provides an opportunity for real positive achievement; students are able to control the task they set themselves, and have every opportunity to maximize their marks. In the past most syllabuses used the coursework simply to assess experimental and investigative skills, through a series of experiments or a practical investigation. Two of the new specifications have taken the opportunity to broaden the scope of coursework. The Edexcel Salters - Horners Advanced Physics AS course includes a report on a visit. Students must make a visit to an establishment where physics is in action, and then report on how physics is used there. The visit may be to a local garage, supermarket or hospital, but could use any other local resource - or indeed justify that trip to CERN. The location of the visit is limited only by the imagination of teachers and students. In the AS course of OCR Advancing Physics students must make a presentation about a material they have studied. The presentation may be a talk, a poster or even a series of web pages. This gives students the opportunity to demonstrate their key skills in communication alongside collecting some marks towards their AS in Physics. In the A2 year students develop their research skills further by producing a research report on a topic of their choice. Students must show how they can draw together ideas from different aspects of physics in discussing their chosen subject. These two developments lead the way in encouraging teachers and examiners to take physics out of the school laboratory and into the world. Mary Whitehouse

    (post16) Making physics connect Doesn't Melvyn Bragg do a wonderful job, engaging both scientists and artists in sensitive discussion on Radio 4 about their methods and their purposes? But every week teachers have the chance to show their students that physics is a way of seeing the world that is well-connected with other aspects of knowledge and culture. The stakes are high: students who fail to appreciate this generally choose not to study the subject beyond GCSE. Most students find our preoccupation with technical detail off-putting. Accepting that we have a syllabus to cover, it's still a question of balance. In our teaching we should aim for variety in order to find ways to connect with every student's interests. Also, we can show that we (the nearest embodiment of a physicist some students will experience) are multidimensional and so fully human. Most important, teachers need flexibility to both encourage and respond to student comment and questions. The first booklet in the discussion series Shaping the Future takes up these themes. Rich in ideas for both immediate use and the longer term, it aims to stimulate debate and improve teaching. Copies cost £5.50 including postage and are available from Ingrid Ebeyer, Post-16 Initiative, Institute of Physics, 76 Portland Place, London W1N 3DH. How far is it? This question is asked in many family cars and school minibuses at the start of a journey, and answered by most in terms of hours and minutes rather than miles. What a good idea for introducing a social and historical perspective to a lesson on distance, velocity and time. How far can you actually get in a day? What is the range of human activity? Walking for eight hours will get many people about 25 miles. A pack horse will progress at much the same rate, but fast riding or a coach and team of horses will get further. Motorway driving (when the cones are on holiday) would take you nearly 500 miles. The 05.15 am train from Penzance arrives in Inverness at 7.15 pm. Twelve hours travel by air will reach the other side of the world. Given such a change in the range of human activity, is it surprising that society has changed and adapted, and some historical incidents and lifestyles hardly make sense? The journals of Dorothy Wordsworth describe a life spent at walking pace. Jane Austen's novels take place at horse speed. Many modern novels are of the jet age, and world travel is part of the plot. Reading accounts of warfare, we must remember that an army perhaps moved 15 miles a day if it hurried (and arrived exhausted). It becomes very clear why Britain could be several independent kingdoms. Turning to another area of physics, we might even speculate how easy life for Romeo and Juliet would have been with a mobile phone each.

    Background In spite of the large body of evidence available in the literature, definition and treatment of Post-Herpetic Neuralgia (PHN) are still lacking a consistent and universally recognized standardization. Furthermore, many issues concerning diagnosis, prediction and prevention of PHN need to be clarified in view of recent contributions. Objectives To assess whether PHN may be better defined, predicted, treated and prevented in light of recent data, and whether available alternative or adjunctive therapies may improve pain relief in treatment recalcitrant PHN. Methods Systematic reviews, meta-analyses, randomized controlled trials, cohort studies and protocols were searched; the search sources included PubMed, Cochrane Library, NICE, and DARE. More than 130 papers were selected and evaluated. Results Diagnosis of PHN is essentially clinical, but it can be improved by resorting to the many tools available, including some practical and accessible questionnaires. Prediction of PHN can be now much more accurate, taking into consideration a few well validated clinical and anamnestic variables. Treatment of PHN is presently based on a well characterized array of drugs and drug associations, including, among others, tricyclic antidepressants, gabapentinoids, opioids and many topical formulations. It is still unsatisfactory, however, in a substantial proportion of patients, especially those with many comorbidities and intense pain at herpes zoster (HZ) presentation, so that this frequent complication of HZ still strongly impacts on the quality of life of affected patients. Conclusion Further efforts are needed to improve the management of PHN. Potentially relevant interventions may include early antiviral therapy of acute HZ, prevention of HZ by adult vaccination, as well as new therapeutic approaches for patients experiencing PHN.

    The nuclear test Dalhart, U4u, was executed at a depth of 2100 ft on October 13, 1988. This test has multiple radioactive isotopes or fission products associated with it and knowledge of the distribution of these isotopes is desirable for the Nuclear Test Program. A slant post shot hole was drilled in late August 1990 to sample the geologic material from the collapsed zone or chimney above Dalhart. This 9 7/8 inch borehole was drilled at approximately 19 degrees from the vertical toward the Dalhart executive depth. This borehole started at approximately 734 ft due south of the Dalhart event. Drilling circulation was lost at a slant depth of 1030 ft (980 ft True Vertical Depth, TVD). Drilling was completed to 2280 ft (2156 ft TVD). The water level was encountered at a depth of 1063 ft (1513 ft TVD). A Halliburton 1 11/16 in diameter TracerScan gamma-ray-spectroscopy log was run inside the drill string at a speed of 10 ft/min. Spectra were obtained from TD to the surface. Radioactive material produced by the test was present from TD to 1850 ft (1746 ft TVD). Spectra were acquired at .025 ft depth intervals and averages recorded digitally every ten ft and thirty ft were displayed on the blue line log together with the total observed gamma ray and casing collar locater signal. Also a DOE high intensity gamma log was run by Atlas Wireline Services from TD to the surface. This log did not detect any radioactive activity in the hole. The gamma-ray photo peaks on the spectroscopy log were used to determine the depths for sampling with the Hunt sidewall sampling tool. Eleven samples were acquired from the depth interval 2212 ft to 1823 ft (2089 to 1721 ft TVD). None of these samples contained enough activity to be measured with normal drillback survey instruments. 7 refs., 8 figs., 3 tabs.

    Post-16 Initiative logo Physics in Mathematical Mood Later this year, as part of the post-16 initiative of the Institute of Physics, a booklet with the above title will be published. In draft form, the booklet was discussed at the ASE conference in January. Some of the issues raised are briefly set out here. If you have any views to contribute, please write to Simon Carson at the Institute of Physics or e-mail simon.carson@physics.org. A mathematical view of the world is intrinsically a part of physics and therefore physics should be studied in an appropriately mathematical way. However, we all know that, to some students at least, mathematics proves to be a stumbling block rather than a powerful aid to understanding. So how can we help? Realizing that as physics teachers we need to deliver the mathematics necessary to an understanding of our subject is a start. Its corollary is that we need to find the space within the physics core. We may wish to use supplementary courses such as AS mathematics or QCA's new free-standing mathematics units, but requiring additional courses as a prerequisite to a study of A-level physics may deter students. Teaching the mathematics in context may aid understanding but we also must ensure that techniques are seen in a variety of contexts and that at some point the tool is abstracted from the background. As teachers we need to be aware of the very basic mathematical difficulties that students bring with them: the use of calculators, standard form, simple algebraic manipulation, for example. Mathematical arguments need to be developed fully and carefully. Encouraging cooperation and discussion between students may help the less able to understand and the more able to appreciate and develop their own understanding through making explicit their reasoning by explaining it to others. And what of new technology? Software tools allow students to develop their understanding about graphs, for example, enabling them to investigate the characteristics of particular functions. Modelling tools allow teachers or students to build models or more simply to create animations to demonstrate the properties of mathematical entities such as vectors. Graphical calculators mean that all students can have cheap access to such tools and it may be that some of the analytical mathematical tools we hold so dear are obsolete. Other issues are discussed in the booklet and were aired at the ASE conference: the situation in HE, the approach to mathematics taken by the Salters Horners approach, ways to introduce special functions such as exponentials, ways of thinking about the relationships between variables as expressed in equations. Many practical suggestions are made in the booklet about how we can help and support students and, most importantly, how we can communicate to them some of the beauty and pleasure of Physics in Mathematical Mood. Simon Carson A perspective on apparatus The effective deployment of apparatus is one technique available in physics that does not exist in some other areas of teaching. We should capitalize on this. Apparatus is a tool that can be used to enable thinking and learning. There are a number of purposes to be served by the effective use of apparatus. It is no more likely that apparatus will `teach' any more than nature `teaches' physics in the first place. Discussion and the creative interpretation of observation are both necessary to the sense-making process. Apparatus must be chosen with these opportunities in mind. In a demonstration we are trying to persuade students that the world behaves in a particular way. An attempt is being made to persuade students that a particular conception of the world is worth considering and that this conception is a fruitful and truthful picture of the world. Apparatus chosen for this purpose must have clear links between what is to be measured and the representations of that measurement. The art of demonstration is very much like a magician's show, in that it must all be well rehearsed and produce surprising and convincing results with apparently little effort. Students will be asked to engage in exploration and explanation using apparatus. Apparatus chosen for this purpose must not look as if it has been designed to give one specific answer. Students must feel confident that they can manipulate apparatus in such a way that the apparatus can serve to express their thoughts and be shaped to try out their hypotheses. Students will also be asked to engage in more traditional laboratory work that requires precision and a careful approach. Here the apparatus must be of sufficient quality and perceived modernity to allow the students to take the tasks seriously so that they will produce work of the expected quality. A final use for apparatus is to allow students to engage in genuine open-ended investigation where their knowledge of physics both informs their plans before work is carried out and interprets the observations and measurements from that work. Here apparatus that measures well is at a premium. The connection between manipulating the system to be measured and the resultant measurement must involve short-term feedback loops: the students must see how the system is behaving. A necessary consequence of this requirement is that the measurements are presented in a form that makes physical sense. This may imply a good deal of processing of the raw data before the number is displayed. It is in this area of measurement that we see the greatest potential for the integration of IT into laboratory practice. Apparatus worth developing. From this analysis and from the experience of trying to make its current practicals work it seems that we need to concentrate our development of apparatus in two areas. The first is to ensure that equipment which provides a range of a high quality, attractive and effective measurement tools is in place. In this area we can expect to see the exploitation of developments in information and sensor technology lead to new approaches which open up many possibilities. The second thrust must be to have a good supply of apparatus which can be can assembled and manipulated by students to suit their thoughts and purposes. This apparatus may well be rather simple and need not to be very expensive. This may compensate for some of the implied expense of the first thrust above. Alongside these two there will continue to be steady development of traditional apparatus, often used for a demonstration. Affording apparatus. The key to developing the apparatus within a department must be to look towards fewer items, each of which can perform more tasks, deployed as measurement tools. In this the increasing computing power available, often at a small cost, can be deployed intelligently. Following a practice elsewhere we must expect most of this development to take place in software, not the hardware. This has clear implications for the apparatus manufacturers. Low costs in computing have followed from the adoption of the widespread standards that enable one device to be used for many purposes. A similar development seems likely in the provision of apparatus. Some elements are likely to prove expensive. Compensating for the use of these expensive elements will then prove to be the challenge which makes the whole package affordable. Building up a department. Out of the post-16 initiative will come some thoughts developed from Advancing Physics that show how we can move from the current provision. New and effectively deployed apparatus can lead to an improvement in teaching and learning and in students' perceptions of physics. Ian Lawrence

  12. Coagulopathy post peritoneovenous shunt.

    In 1942, 53% of medically treated patients with cirrhosis were dead 6 months after the onset of ascites. Only 30% survived 1 year. This dismal outlook has improved only slightly with advances in medicine. Yet, some internists reject the peritoneovenous shunt (PVS) for this fatal condition even if they are aware that a diminished blood volume causes the abnormal sodium retention responsible for ascites. Their objections are based on life-threatening complications of PVS, especially post shunt coagulopathy (PSC). Blood shed into the peritoneal cavity becomes incoagulable. Such blood is immediately coagulated by a protocoagulant (soluble collagen) and concurrently lysed by tissue plasminogen activator (TPA) secreted by the peritoneal serosa. Wide zones of lysis surround peritoneal tissue placed on fibrin plates. Large volumes of ascitic fluid infused into circulating blood simulates the fate of blood shed into the peritoneal cavity with lysis playing the major role. Addition of ascitic fluid to normal platelet-rich plasma in vitro initiates clot lysis on thromboelastogram (TEG). Epsilon-aminocaproic acid (EACA) counteracts this lysis. EACA and clotting factors normalize the TEG and arrest PSC. Disposal of ascitic fluid at surgery prevents or ameliorates PSC. Mild PSC was encountered only twice in 150+ consecutive patients (1.3%) with only one case being clinically significant (0.6%). Severe PSC occurred seven times in 98 early shunt patients whose ascitic fluid was not discarded. Severe PSC requires shunt interruption and control of bleeding with clotting factors and EACA. Peritoneal lavage with saline prevents the recurrence of PSC on reopening the shunt. In four patients, EACA and clotting factors were adequate to arrest coagulopathy. Three earlier patients died of PSC before its cause and treatment were understood. Proper management eliminates this life-threatening complication, and PSC cannot be considered a deterrent to PVS. Disseminated intravascular coagulopathy (DIC) is produced in experimental animals only by the injection of thrombin or thromboplastin. PSC is a distinct entity differing from DIC; EACA and not heparin is the antidote for PSC. Images Fig. 1. Fig. 2. Fig. 4. Fig. 5. Fig. 6. PMID:3103556

    Hypofolatemia can cause psychiatric disturbances of a depressive nature. Pregnancy and delivery are often associated with hypofolatemia. This study was conducted to determine if hypofolatemia at day 3 post partum is a risk factor for baby blues or post partum depression. To study this hypothesis, 131 post partum women were followed prospectively for the 3 months immediately following delivery. 19% were found to have 'baby blues', as defined by a score greater than 20 on Pitt's scale (Pitt, 1968, J. Psychiatry 114, 1325-1335) and 12% had post partum depression as defined by a score greater than 7 on QD2A scale (Pichot et al., 1984, Rev. Psycholog. App. 34, 229-250, 323-340), within the three months post partum. No relationship was observed between the serum or erythrocyte folate levels on the third day following delivery and the maternal post partum depression scores. A statistically significant correlation between post partum depression and previous psychiatric disturbance was, however, observed. PMID:1430660

    Post-mortem microbiology is useful in both clinical and forensic autopsies, and allows a suspected infection to be confirmed. Indeed, it is routinely applied to donor studies in the clinical setting, as well as in sudden and unexpected death in the forensic field. Implementation of specific sampling techniques in autopsy can minimize the possibility of contamination, making interpretation of the results easier. Specific interpretation criteria for post-mortem cultures, the use of molecular diagnosis, and its fusion with molecular biology and histopathology have led to post-mortem microbiology playing a major role in autopsy. Multidisciplinary work involving microbiologists, pathologists, and forensic physicians will help to improve the achievements of post-mortem microbiology, prevent infectious diseases, and contribute to a healthier population.

    Institute of Physics post-16 initiative, shaping the future Physics education based in IT - sorry ICT! Which, of course, makes for a nifty headline, but as is so often the case with neat slogans, little else. Two formative questions: What, in another decade, will the government of the day call `What you lot should be doing with computers'? and What, of the many things that currently exercise our intellects, will there be anything special to say about in a decade, concerning the use of computers in the teaching of physics? Advancing Physics represents some attempts to come to grips with the second of the two questions above. The first is left to a higher wisdom. In thinking about learning, what can we do with the huge processing power, increasingly available in smaller and less obtrusive packages? What will we do that helps people learn physics, both tomorrow and in 2009? Here are a few suggestions based on development work so far. Wide, reliable and shared access to well ordered learning resources. We have created a CD-ROM, with versions for both student and teacher, that provides a wide range of resources. These do not teach, but do provide. A commitment to allowing a course to evolve and adapt. Electronic publication puts the costs into origination, and not into publication and distribution. A website allows for the community of users to contribute. E-mail networks support individuals and propagate good practice. You can create and explore your own microworlds. The interactive nature of models, and the crafted relationships between the models and the natural world give an insight into the creative imaginary worlds of the physicist. The unreasonable, but pleasurable, success of mathematics in describing the natural world can come to the fore. Measurements that were not possible before are now possible. What was previously indirect, and inaccessible, now becomes a direct measurement, making relationships transparent in new and fruitful ways. The dichotomy between measured and fundamental variables can be resolved along a number of different axes. Shaping data to create understanding is also possible. Plotting, re-expressing and re-plotting can all happen within a time-span that retains the connections to the original physical situation. Making sense of the data can become a more active and integral part of doing physics. Two advantages for physics teachers: Firstly, the computer is another piece of equipment - one amongst the many that we already deploy based on our considerable experience. It may be a better intellectual prosthetic than some, but it is just one amongst many: good for some things, not to be let near others. Secondly, physics necessarily describes nature. Thus the chance of losing contact with our roots in a virtual canopy is slim; nurture and insight will always come from interaction with the physical. A summative question: Which, of the information and communication technologies available to students, is the most effective in stimulating, promoting and nurturing learning? (The more astute reader will notice the discontinuity between the implications of the embracing title, ICT, and the rather narrower, what we do with computers, somewhat closer to the current obsessions, rather meekly followed by the author in this piece. This final question has only one correct answer, several ramifications, and seeks to redress the balance lacking in the rest of this brief survey.) Ian Lawrence Maps and vectors Where would we be without vectors? Vectors are vital to a proper description of a variety of phenomena in physics. They are also notoriously difficult for students to come to terms with. Many students meet vectors for the first time in their A-level physics course when they learn mechanics. And this topic is often taught first. The vectors they meet - velocity, acceleration, force - can seem rather abstract, and acceleration in particular, being a rate of change of a rate of change, is fraught with conceptual difficulties. When students meet vectors, they are taught to add them, to subtract them to find components in various directions. This means they have to come to grips with Pythagoras's theorem and with trigonometry at the same time as learning the rules about how vectors behave: the magnitude of the sum is not the same as the sum of the magnitudes, for example. Rather than developing ideas about vectors at the same time as the difficult ideas encapsulated in Newton's laws, perhaps it might be better to develop a physical understanding of what vectors are and of how they combine first. One way of doing this is by considering maps: these represent, on a two-dimensional sheet of paper, the topology of a landscape. A road map represents a layout of towns, and by considering (straight line) journeys from town to town, ideas about vector addition can be developed: going from town A to town C via town B can be represented by the addition of two displacement vectors. And if these three towns are not in a straight line, then the magnitude of the sum is not the same as the sum of the magnitudes (the magnitude here is the straight line distance, of course). What's more, knowing the straight line distances between a small collection of towns - similar tables of distances can be found in many road atlases - allows the map to be reconstructed. But unless you know which way is north, the distances themselves give only the relative positions of the towns. Notice that these relative positions do not depend on the coordinate system (determined by our choice of north) so that vector sums are coordinate independent. Introducing a coordinate system - defined by compass directions - and thinking about how far north or east a particular journey takes you leads to ideas about components. And considering a map of mountainous country means that you can think about how three components can be represented on a flat piece of paper. This leads to generalizations of Pythagoras's theorem in three dimensions. Perhaps these ideas might help students to develop an intuitive understanding of what vectors are about. When they meet more complex and abstract ideas they might, then, see their way through the mathematical representations to the underlying physics. We might have to spend more time teaching the basics, but the pay-off could be a much better understanding later. Simon Carson

    The traumatic lesions during surgical interventions often turn into a persistent pain. Pain persists in the location of surgical intervention for a long time, beyond the usual course of natural healing of an acute pain and it is different from that suffered preoperatively. It is usually a chronic pain and it is associated to lesions of the central or peripheral nervous system. Pain is usually described as burning or tingling, or electric shock-like; it can be continuous or parossistic, often associated to paraesthesia, iperalgesia and allodinya. If circumstances preclude the surgical revision, the treatment of post-surgical neuropathic pain is based on drugs, according to the guidelines. The drugs of choice are the tricyclic antidepressants, the serotonin and adrenaline re-uptake selective inhibitors (SSRI), local antiepileptics of new generation (gabapentin, pregabalin) and topical anaesthetics. Drugs of second line are: opioid analgesics, tramadol; drugs of third line are: mexiletine, antagonist of NMDA receptor and capsaicine. The post-surgical neuropathic pain is often resistant to the pharmacologic treatment; for this reason the spinal cord neuromodulation can be applied only after careful selection of the patients according to the international guidelines. The incidence of post-surgical neuropathic pain in the Pain Units is approximately 20% of the patients admitted to hospital. Therefore it is necessary a greater attention for the post-surgical analgesia, adopting appropriate surgical techniques in order to avoid the onset of the post-surgical neuropathic pain.

  19. What about ex post facto

    McKee, H.C.

    This note presents a legal question in an attempt to find an answer. The author hopes that some legal scholar can explain the principle of ex post facto in the US Constitution as it applies to some of the environmental laws. One of the major advantages of the Association is that it provides a forum for communication among members with different backgrounds and experience. An ex post facto law is one that is applied retroactively. Under such a law, a person could be punished for some act that violated a law passed after the act was committed, even though the act was legal when committed. The US Constitution prohibits such laws, as will be discussed later. States are also prohibited from enacting ex post facto laws.

    Formulae and numerical results are presented for the gravitational radiation emitted during a low-deflection encounter between two massive bodies. Results are valid through post-Newtonian order within general relativity. The gravitational waveform, the total luminosity and total emitted energy, the angular distribution of emitted energy, and the frequency spectrum are discussed in detail. A method boosting the accuracy of these quantities to post Newtonian order is also presented. A numerical comparison of results with those of Peters, and of Kovacs and Thorne shows that the post Newtonian method is reliable to better than 0.1 percent at v = 0.1 c, to a few percent at v = 0.35 c, and to 10 to 20 percent at v = 0.5 c.

  3. Post-hepatectomy liver failure.

    PubMed

    Kauffmann, Rondi; Fong, Yuman

    2014-10-01

    Hepatectomies are among some of the most complex operative interventions performed. Mortality rates after major hepatectomy are as high as 30%, with post-hepatic liver failure (PHLF) representing the major source of morbidity and mortality. We present a review of PHLF, including the current definition, predictive factors, pre-operative risk assessment, techniques to prevent PHLF, identification and management. Despite great improvements in morbidity and mortality, liver surgery continues to demand excellent clinical judgement in selecting patients for surgery. Appropriate choice of pre-operative techniques to improve the functional liver remnant (FLR), fastidious surgical technique, and excellent post-operative management are essential to optimize patient outcomes.

    1984-04-01

    Among various two-phase flow regimes, the inverted flow in the post-dryout region is relatively less well understood due to its special heat transfer conditions. The review of existing data indicates further research is needed in the areas of basic hydrodynamics related to liquid core disintegration mechanisms, slug and droplet formations, entrainment, and droplet size distributions. In view of this, the inverted flow is studied in detail both analytically and experimentally. Criteria for initial flow regimes in the post-dryout region are given. Preliminary models for subsequent flow regime transition criteria are derived together with correlations for a mean droplet diameter based on the adiabatic simulation data.

  5. Post-traumatic spinal deformity.

    PubMed

    Vaccaro, A R; Silber, J S

    2001-12-15

    There are approximately 50,000 fractures to the bony spinal column each year in the United States. The vast majority of unstable spinal injuries are recognized early and managed appropriately. Rarely, the initial treatment may have been inadequate, or in less obvious injuries, less aggressive immobilization techniques may have been chosen. This along with continued exposure to physiologic stresses may lead to a gradual post-traumatic deformity that may further impede the functional as well as emotional status of these often already compromised patients. The management of post-traumatic deformity can be extremely challenging. A post-traumatic kyphotic deformity may occur in the cervical, thoracic, thoracolumbar, or lumbar spine, and once appropriate imaging studies are obtained, careful surgical considerations must be undertaken. Surgical intervention is considered if the kyphotic deformity is progressive over time or there is new onset or progression of a neurologic deficit. Surgical procedures include either a posterior or anterior only approach or any variation of a combined anterior or posterior procedure. In most cases a posterior only fusion is often insufficient for optimal correction and stabilization. Although the majority of patients developing a post-traumatic deformity usually occur after spinal column trauma initially treated nonoperatively, several miscellaneous causes of post-traumatic deformity may occur after surgery. These include nonunion, implant failure, Charcot spine, and technical error. The overall outcome after the surgical management of post-traumatic deformity has been satisfactory with better outcomes in the patients treated earlier as opposed to later. Operative complications include the increased risk of neurologic injury because of the draping of the neural elements over the anterior vertebral elements, any pre-existing spinal cord injury, and possible scarring with cord tethering. Trauma to the spinal cord and column is a devastating injury that may be fraught with many complications including post-traumatic deformity. Certainly, the best treatment is prevention with close follow-up and early intervention when needed. Once present, the treatment of post-traumatic deformity follows basic biomechanical principles consisting of re-establishing the integrity of the compromised spinal columns so that spinal stability can be restored.

  12. Tuberculosis drug discovery in the post-post-genomic era

    2014-01-01

    The expectation that genomics would result in new therapeutic interventions for infectious diseases remains unfulfilled. In the post-genomic era, the decade immediately following the availability of the genome sequence of Mycobacterium tuberculosis, tuberculosis (TB) drug discovery relied heavily on the target-based approach but this proved unsuccessful leading to a return to whole cell screening. Genomics underpinned screening by providing knowledge and many enabling technologies, most importantly whole genome resequencing to find resistance mutations and targets, and this resulted in a selection of leads and new TB drug candidates that are reviewed here. Unexpectedly, many new targets were found to be promiscuous as they were inhibited by a variety of different compounds. In the post-post-genomics era, more advanced technologies have been implemented and these include high-content screening, screening for inhibitors of latency, the use of conditional knock-down mutants for validated targets and siRNA screens. In addition, immunomodulation and pharmacological manipulation of host functions are being explored in an attempt to widen our therapeutic options. PMID:24401837

    The Canadian Meteorological Centre (CMC) delivers a large number of numerical weather prediction products to the various weather offices and clients throughout Canada and abroad. The current post production system was built according to the needs and ideology of the 1980's and it is becoming obsolete with time. Its cumbersome architecture is difficult to maintain and requires a lot of human and computing resources. The "Weather Elements" section of CMC is aware of the problems associated with its maintenance in the long term and has therefore decided to review in depth the whole approach to the operational post production. The analysis of present and future needs have led to the development of an innovative concept in the operational production field inspired by the "Plug and Play" process. SPOOKI (Systme de Production Orient-Objet contennant une Kyrielle d'Informations - Object oriented production system containing a myriad of information) was created in its present form in 2007. It is based on a modular approach where each plug-in component is specialized, reusable and autonomous. These object oriented programming characteristics greatly simplify the maintenance of the system. Particular attention was also given to create a user-friendly system for novice users. An experimental version of SPOOKI is currently running in development mode and an operational one is planned to be implemented in the coming year. The poster presentation will describe SPOOKI, the future CMC operational post production system. Several examples of usage will be shown.

    Post-penetrating keratoplasty (post-PK) glaucoma is an important cause of irreversible visual loss and graft failure. The etiology for this disorder is multifactorial, and with the use of new diagnostic equipment, it is now possible to elucidate the exact pathophysiology of this condition. A clear understanding of the various mechanisms that operate during different time frames following PK is essential to chalk out the appropriate management algorithms. The various issues with regard to its management, including the putative risk factors, intraocular pressure (IOP) assessment post-PK, difficulties in monitoring with regard to the visual fields and optic nerve evaluation, are discussed. A step-wise approach to management starting from the medical management to surgery with and without metabolites and the various cycloablative procedures in cases of failed filtering procedures and excessive perilimbal scarring is presented. Finally, the important issue of minimizing the incidence of glaucoma following PK, especially through the use of oversized grafts and iris tightening procedures in the form of concomitant iridoplasty are emphasized. It is important to weigh the risk-benefit ratio of any modality used in the treatment of this condition as procedures aimed at IOP reduction, namely trabeculectomy with antimetabolites, and glaucoma drainage devices can trigger graft rejection, whereas cyclodestructive procedures can not only cause graft failure but also precipitate phthisis bulbi. Watchful expectancy and optimal time of intervention can salvage both graft and vision in this challenging condition. PMID:18579984

  2. Statins for post resuscitation syndrome.

    PubMed

    Kämäräinen, Antti; Virkkunen, Ilkka; Silfvast, Tom; Tenhunen, Jyrki

    2009-07-01

    After sudden cardiac arrest, successful resuscitation and return of spontaneous circulation, a multi-faceted ischaemia/reperfusion related disorder develops. This condition now known as post resuscitation syndrome is characterised by marked increases in the inflammatory response and changes in coagulation profile and vascular reactivity. Additionally, the production of reactive oxygen species and activation of cytotoxic cascades of metabolism add to these injury mechanisms resulting in multiorgan perfusion deficits and dysfunction. Especially in the cerebrum these injuries may be the cause of significant morbidity and mortality. Recent evidence has shown that statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) exert numerous beneficial effects in cardiovascular diseases irrespective of the lipid status. Remarkably, these pleiotropic effects seem to extended beyond cardiovascular diseases such as immunomodulative and antioxidative properties. We hypothesised that administration of statins early in the post resuscitation phase would prove beneficial in the resuscitated patient via several pleiotropic effects. These include inhibition of excessive coagulation and inflammatory response, suppression of oxygen radical production and improved vascular reactivity. The discussed effects are mediated via multiple pathways activated in the cardiac arrest victim, to which statins have been shown to have a beneficial modulating effect in experimental settings and non-cardiac arrest patients. To test this hypothesis in clinical practice, a randomized, controlled trial with sufficient power and standardised post resuscitation treatment would be necessary. The generally good tolerance of statin therapy with minimal adverse effects would support this experiment, although a parenteral form of the drug to ensure adequate dosage might be a prerequisite.

    Psychosocial support and careful monitoring are recommended for acute stress reaction (ASR) and acute stress disorder (ASD). If symptoms require, short focused cognitive-behavioural psychotherapy can be used for ASD. Medication is rarely necessary, but sleeping pills can be used for a short period. Trauma-focused psychotherapeutic interventions are first-line treatment for post-traumatic stress disorder. SSRI or SNRI antidepressant medication is also effective. There is less evidence on antipsychotic and antiepileptic medication. Psychotherapeutic interventions and medication can be, and often are, combined. Children, the elderly, and military and peacekeeping personnel need interventions that are tailored to their needs. PMID:19839195

    Lyme disease is a chronic infectious disease caused by the bacteria, spirochete of the Borrelia type. Skin, nervous system, musculoskeletal system and heart may be involved in the course of the disease. The prognosis for properly treated Lyme disease is usually good. However, in about 5% of patients so called Post-Lyme disease syndrome (PLSD) develops. It is defined as a syndrome of subjective symptoms persisting despite proper treatment of Borrelia burgdorferi infection. The most common symptoms include: fatigue, muscle and joint pain, and problems with memory and concentration. Pathogenesis of PLDS remains unknown. The differential diagnosis should include neurological, rheumatic and mental diseases. Till now there is no causative treatment of PLDS. In relieving symptom rehabilitation, painkillers, anti-inflammatory and antidepressants medicines are recommended. Emotional and psychological supports are also necessary. Non-specific symptoms reported by patients with post- Lyme disease syndrome raise the suspicion of other pathologies. This can lead to misdiagnosis and implementation of unnecessary, potentially harmful to the patient's therapy.

    Any surgical approach modifies the normal anatomical and functional arrangement of the segmental spine which is aimed, therefore image interpretation cannot ignore a correct set of knowledge in the field of anatomy, pathophysiology, drug compliance, interventional radiology and surgery. Neuroradiological imaging has an important role before surgery to direct the surgeon or interventional radiologist during the operation, both in post-surgery, where imaging examination can rightly evaluate properties and effects of the treatment and can detect potential complications as infections, abscess, bleeding, exuberant scar, mobilization and rupture of devices. The available methods of imaging are the X-rays (XR) made at least in two projections, Computed Tomography (CT) with MPR (multiplanar) and VR (volume rendering) reconstruction, and Magnetic Resonance (MR), often performed before and after contrast media injection. Imaging assessment of spine after surgery is complex and depends upon several factors, including surgical procedures and disease for which it was performed; biomechanical of the underlying cortical and cancellous bone findings; conditions of muscles, intervertebral disk and ligaments; time since surgery procedures; duration and nature of the post-surgical syndrome. Depending upon several factors, one or a combination of complementary imaging modalities (X-rays, Computed Tomography, Magnetic Resonance) may be required to evaluate effectiveness of the treatment; to demonstrate any clinically relevant abnormality at the treated region and adjacent structures (complications such as inflammation, abscesses, bleeding and misplacement of the device); to assist the interventional radiologist or surgeon in deciding if is necessary intervene again, in which nature and in which vertebral level(s).

  10. Gynecologic Malignancies Post-LeFort Colpocleisis

    PubMed Central

    2014-01-01

    Introduction. LeFort colpocleisis (LFC) is a safe and effective obliterative surgical option for older women with advanced pelvic organ prolapse who no longer desire coital activity. A major disadvantage is the limited ability to evaluate for post-LFC gynecologic malignancies. Methods. We present the first case of endometrioid ovarian cancer diagnosed after LFC and review all reported gynecologic malignancies post-LFC in the English medical literature. Results. This is the second reported ovarian cancer post-LFC and the first of the endometrioid subtype. A total of nine other gynecologic malignancies post-LFC have been reported in the English medical literature. Conclusions. Gynecologic malignancies post-LFC are rare. We propose a simple 3-step strategy in evaluating post-LFC malignancies. PMID:25525536

    This software tool saves time and reduces risk by automating two labor-intensive and error-prone post-processing steps required for every DKF [DSN (Deep Space Network) Keyword File] that MRO (Mars Reconnaissance Orbiter) produces, and is being extended to post-process the corresponding TSOE (Text Sequence Of Events) as well. The need for this post-processing step stems from limitations in the seq-gen modeling resulting in incorrect DKF generation that is then cleaned up in post-processing.

    Objective: The effects of closely adapting a prefabricated fiber to the post space remain unknown. The purpose of this study was to quantify the microleakages of a custom adapted fiber-reinforced post, a prefabricated quartz fiber post and a cast post using nondestructive methods. Materials and Methods: Sixty-five extracted human premolars were endodontically treated and randomly divided into three groups (n=15), which were restored using a cast post-and-core, a custom adapted fiber post (Refropost) with a microhybrid microfiller resin composite (Gradia), or a prefabricated quartz fiber post (DT light post) and two groups of control (n=10). All groups were cemented using a dual polymerizing resin cement (Panavia F2.0). A composite core (Z100) was used for the fiber posts. The microleakage was calculated for the experimental and control groups before and after thermal cycling and cycling loading using a radiotracer solution (thallium 201 chloride) and a gamma counter device. Data were subjected to statistical analysis of ANOVA and Tukey HSD at significant level of P< 0.05. Results: Significantly lower microleakage values were found for the cast post-and-core (mean value =16.04 104) and custom adapted fiber post groups (mean value=14.36104). Thermal cycling and cyclic loading had no significant effect on the microleakage value of any tested group. Conclusion: Post systems with improved adaptation showed similar microleakage to casting posts. PMID:23724207

    Post-infectious bronchiolitis obliterans (BO) is characterized by inflammatory and fibrotic lesions of small airways following a pulmonary infection and leading to some degree of airway obstruction. It represents a rare cause of chronic obstructive pulmonary disease, and is probably underestimated, especially when the lesions affect small areas of the lungs. The clinical features differ between children and adults. In children, adenovirus is the most frequently involved infectious agent, especially the more virulent serotypes 3, 7 and 21. The clinical and radiological signs vary widely and the functional outcome depends on the extent of the lung injury. The diagnosis is based on the medical history, the CT-scan and functional data. The treatment is symptomatic. The most severe forms may result in chronic respiratory insufficiency. In adults, the frequency of obstructive injuries of the small airways in the context of lung infection is unclear. Parenchymal lesions are often present, resulting in BO with organizing pneumonia. These lesions alter the clinical presentation and the radiographic features of the initial infectious disease and often prove difficult to diagnose and manage. Several authors have published clinical cases describing presumed efficacy of systemic corticosteroids but the data are scarce. PMID:23419446

    Pelvic-perineal dysfunctions, are the most common diseases in women after pregnancy. Urinary incontinence and genital prolapsy, often associated, are the most important consequences of childbirth and are determined by specific alterations in the structure of neurological and musculo-fascial pelvic support.Causation is difficult to prove because symptom occur remote from delivery.Furthermore it is unclear whether changes are secondary to the method of childbirth or to the pregnancy itself.This controversy fuels the debate about whether or not women should be offered the choice of elective caesarean delivery to avoid the development of subsequent pelvic floor disfunction.But it has been demonstrated that pregnancy itself, by means of mechanical changes of pelvic statics and changes in hormones, can be a significant risk factor for these diseases. Especially is the first child to be decisive for the stability of the pelvic floor.During pregnancy, the progressive increase in volume of the uterus subject perineal structures to a major overload. During delivery, the parties present and passes through the urogenital hiatus leading to growing pressure on the tissues causing the stretching of the pelvic floor with possible muscle damage, connective tissue and / or nervous.In this article we aim to describe genitourinary post partum changes with particular attention to the impact of pregnancy or childbirth on these changes.

  7. CID Post-impact fireball

    NASA Technical Reports Server (NTRS)

    1984-01-01

    Following its controlled impact on posts imbedded in the lakebed, the B-720 is sliding sideways and almost enveloped in the large fireball with only the aircraft's nose and right wing-tip exposed. In a typical aircraft crash, fuel spilled from ruptured fuel tanks forms a fine mist that can be ignited by a number of sources at the crash site. In 1984 the NASA Dryden Flight Research Facility (after 1994 a full-fledged Center again) and the Federal Aviation Administration (FAA) teamed-up in a unique flight experiment called the Controlled Impact Demonstration (CID), to test crash a Boeing 720 aircraft using standard fuel with an additive designed to supress fire. The additive, FM-9, a high-molecular-weight long-chain polymer, when blended with Jet-A fuel had demonstrated the capability to inhibit ignition and flame propagation of the released fuel in simulated crash tests. This anti-misting kerosene (AMK) cannot be introduced directly into a gas turbine engine due to several possible problems such as clogging of filters. The AMK must be restored to almost Jet-A before being introduced into the engine for burning. This restoration is called 'degradation' and was accomplished on the B-720 using a device called a 'degrader.' Each of the four Pratt & Whitney JT3C-7 engines had a 'degrader' built and installed by General Electric (GE) to break down and return the AMK to near Jet-A quality. In addition to the AMK research the NASA Langley Research Center was involved in a structural loads measurement experiment, which included having instrumented dummies filling the seats in the passenger compartment. Before the final flight on December 1, 1984, more than four years of effort passed trying to set-up final impact conditions considered survivable by the FAA. During those years while 14 flights with crews were flown the following major efforts were underway: NASA Dryden developed the remote piloting techniques necessary for the B-720 to fly as a drone aircraft; General Electric installed and tested four degraders (one on each engine); and the FAA refined AMK (blending, testing, and fueling a full-size aircraft). The 15 flights had 15 takeoffs, 14 landings and a larger number of approaches to about 150 feet above the prepared crash site under remote control. These flight were used to introduce AMK one step at a time into some of the fuel tanks and engines while monitoring the performance of the engines. On the final flight (No. 15) with no crew, all fuel tanks were filled with a total of 76,000 pounds of AMK and the remotely-piloted aircraft landed on Rogers Dry Lakebed in an area prepared with posts to test the effectiveness of the AMK in a controlled impact. The CID, which some wags called the Crash in the Desert, was spectacular with a large fireball enveloping and burning the B-720 aircraft. From the standpoint of AMK the test was a major set-back, but for NASA Langley, the data collected on crashworthiness was deemed successful and just as important.

  8. Post-Retrofit Residential Assessments

    This study examined a range of factors influencing energy consumption in households that had participated in residential energy-efficiency upgrades. The study was funded by a grant from the U.S. Department of Energy’s Pacific Northwest National Laboratory and was conducted by faculty and staff of Portland State University Center for Urban Studies and Department of Economics. This work was made possible through the assistance and support of the Energy Trust of Oregon (ETO), whose residential energy-efficiency programs provided the population from which the sample cases were drawn. All households in the study had participated in the ETO Home Performance with Energy Star (HPwES) program. A number of these had concurrently pursued measures through other ETO programs. Post-retrofit energy outcomes are rarely investigated on a house-by-house basis. Rather, aggregate changes are ordinarily the focus of program impact evaluations, with deviation from aggregate expectations chalked up to measurement error, the vagaries of weather and idiosyncrasies of occupants. However, understanding how homes perform post-retrofit on an individual basis can give important insights to increase energy savings at the participant and the programmatic level. Taking a more disaggregated approach, this study analyzed energy consumption data from before and after the retrofit activity and made comparisons with engineering estimates for the upgrades, to identify households that performed differently from what may have been expected based on the estimates. A statistical analysis using hierarchal linear models, which accounted for weather variations, was performed looking separately at gas and electrical use during the periods before and after upgrades took place. A more straightforward comparison of billing data for 12-month periods before and after the intervention was also performed, yielding the majority of the cases examined. The later approach allowed total energy use and costs to be assessed but did not account for weather variation. From this statistical analysis, 18 study participants were selected and interviewed. The participants completed an in-home interview covering a range of topics, including changes in occupancy and additional changes to the homes that may have affected energy use. The goal of the interviews was to identify factors that may have contributed to unusual energy performance. These factors were identified by their frequency of occurrence in outperforming or underperforming homes, or simply by identifying factors that had the largest impact on overall savings. The motivations and levels of satisfaction with the outcomes of the upgrades were covered in detail, as well as extensive discussions of behaviors pertaining to thermal control, lighting, water, and appliance use. Most of cases studied achieved substantial energy savings, although it was more common for the projected savings to be greater than the demonstrated savings. Two factors that played a very large role in savings variation were 1) changes in occupancy and 2) fenestration improvements outside of the incentive programs. Motivation for pursuing the upgrades (e.g., environmental sustainability vs. comfort or cost savings) did not seem to play any role in achieving savings. Participants generally were more concerned with maintaining aesthetics through lighting than comfort through heating or cooling. They also seemed more likely to turn the lights off when leaving a room than to turn the heat off when leaving the home.

  9. Explosive signatures: Pre & post blast

    NASA Astrophysics Data System (ADS)

    Bernier, Evan Thomas

    Manuscripts 1 and 2 of this dissertation both involve the pre-blast detection of trace explosive material. The first manuscript explores the analysis of human hair as an indicator of exposure to explosives. Field analysis of hair for trace explosives is quick and non-invasive, and could prove to be a powerful linkage to physical evidence in the form of bulk explosive material. Individuals tested were involved in studies which required handling or close proximity to bulk high explosives such as TNT, PETN, and RDX. The second manuscript reports the results of research in the design and application of canine training aids for non-traditional, peroxide-based explosives. Organic peroxides such as triacetonetriperoxide (TATP) and hexamethylenetriperoxidediamine (HMTD) can be synthesized relatively easily with store-bought ingredients and have become popular improvised explosives with many terrorist groups. Due to the hazards of handling such sensitive compounds, this research established methods for preparing training aids which contained safe quantities of TATP and HMTD for use in imprinting canines with their characteristic odor. Manuscripts 3 and 4 of this dissertation focus on research conducted to characterize pipe bombs during and after an explosion (post-blast). Pipe bombs represent a large percentage of domestic devices encountered by law enforcement. The current project has involved the preparation and controlled explosion of over 90 pipe bombs of different configurations in order to obtain data on fragmentation patterns, fragment velocity, blast overpressure, and fragmentation distance. Physical data recorded from the collected fragments, such as mass, size, and thickness, was correlated with the relative power of the initial device. Manuscript 4 explores the microstructural analysis of select pipe bomb fragments. Shock-loading of the pipe steel led to plastic deformation and work hardening in the steel grain structure as evidenced by optical microscopy and microhardness testing respectively.

    2010-01-01

    Introduction Post-traumatic stress disorder (PTSD) may affect 10% of women and 5% of men at some stage, and symptoms may persist for several years. Risk factors include major trauma, lack of social support, peritraumatic dissociation, and previous psychiatric history or personality factors. Methods and outcomes We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of interventions to prevent PTSD? What are the effects of interventions to treat PTSD? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2009 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). Results We found 46 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. Conclusions In this systematic review we present information relating to the effectiveness and safety of the following interventions: affect management; antiepileptic drugs; antihypertensive drugs; benzodiazepines; brofaromine; CBT; drama therapy; eye movement desensitisation and reprocessing; fluoxetine; group therapy; hydrocortisone; hypnotherapy; inpatient treatment programmes; Internet-based psychotherapy; mirtazapine; multiple-session CBT; multiple-session collaborative trauma support; multiple-session education; nefazodone; olanzapine; paroxetine; phenelzine; psychodynamic psychotherapy; risperidone; SSRIs (versus other antidepressants); sertraline; single-session group debriefing; single-session individual debriefing; supportive psychotherapy; supportive counselling; temazepam; tricyclic antidepressants; and venlafaxine.

    2012-01-01

    The exact incidence of common post-operative complications in children is not known. Most common one is post-operative nausea and vomiting followed by respiratory complications leading to hypoxia. Cardiac complications are less in children without associated congenital cardiac anomaly. Post-operative shivering, agitation and delirium are seen more often in children anaesthetised with newer inhalational agents like sevoflurane and desflurane. Urinary retention in the post-operative period could be influenced by anaesthetic drugs and regional blocks. The purpose of this article is to review the literature and present to the postgraduate students comprehensive information about the current understanding and practice pattern on various common complications in the post-operative period. Extensive literature was searched with key words of various complications from Pubmed, Google scholar and specific journal, namely paediatric anaesthesia. The relevant articles, review article meta-analysis and editorials were the primary source of information for this article. PMID:23293390

    This report describes research conducted to determine the contamination performance of HVDC station post insulators. The contamination severity on post insulators in four different HVDC converter stations was obtained by a series of field measurements. The data were analyzed to show the effect of polarity, stress, voltage magnitude and distribution of contaminant along and around in the insulators. Recommendations were made for subsequent laboratory evaluation of post insulator flashover strength using the clean fog artificial contamination test, procedure. The effect of shed configuration was investigated in those laboratory tests using full scale station posts with significantly different geometric profiles. Test results were also obtained for naturally contaminated post insulators exposed to DC voltage. Comparisons of HVAC and HVDC contamination performance of post insulators were made in order to relate the DC performance to that of AC where more experience is available. The influence of shape parameters on the accumulation of contaminant was studied by means of a dust deposit chamber. Improvements in the withstand capability of post insulators with special treatments, such as semi-conductive glaze or room temperature vulcanized silicone rubber coatings, were explored. 19 refs.

    Atopic dermatitis and psoriasis are two chronic skin inflammatory diseases that have so far received a greater attention within the scientific community through different post-genomic approaches; on the contrary, acne, which is undoubtedly one of the most common skin disorders involving inflammatory processes, seems to be still quite neglected under the post-genomic point of view. In this paper, we will review how post-genomic technologies have provided new fundamental tools for the analysis of these three conditions and we will cast light on their potential in addressing future research challenges.

    Stroke and epilepsy are two of the most common neurological disorders and share a complicated relationship. It is well established that stroke is one of the most important causes of epilepsy, particularly new-onset epilepsy among the elderly. However, post-epilepsy stroke has been overlooked. In recent years, it has been demonstrated that epilepsy patients have increased risk and mortality from stroke when compared with the general population. Additionally, it was proposed that post-epilepsy stroke might be associated with antiepileptic drugs (AEDs), epileptic seizures and the lifestyle of epileptic patients. Here, we comprehensively review the epidemiology, causes and interventions for post-epilepsy stroke. PMID:26919195

    The B-720 after impact and sliding through the wing openers is becoming enveloped in a fireball. The right wing appears to be folding over as the aircraft continues to slide.

  19. Post-traumatic Stress Disorder.

    Unexpected extreme sudden traumatic stressor may cause post-traumatic stress disorder (PTSD). Important traumatic events include war, violent personal assault (e.g., sexual assault, and physical attack), being taken hostage or kidnapped, confinement as a prisoner of war, torture, terrorist attack, severe car accidents, and natural disasters. In childhood age sexual abuse or witnessing serious injuries or unexpected death of a beloved one are among important traumatic events.PTSD can be categorized into two types of acute and chronic PTSD: if symptoms persist for less than three months, it is termed "acute PTSD," otherwise, it is called "chronic PTSD." 60.7% of men and 51.2% of women would experience at least one potentially traumatic event in their lifetime. The lifetime prevalence of PTSD is significantly higher in women than men. Lifetime prevalence of PTSD varies from 0.3% in China to 6.1% in New Zealand. The prevalence of PTSD in crime victims are between 19% and 75%; rates as high as 80% have been reported following rape. The prevalence of PTSD among direct victims of disasters was reported to be 30%-40%; the rate in rescue workers was 10%-20%. The prevalence of PTSD among police, fire, and emergency service workers ranged from 6%-32%. An overall prevalence rate of 4% for the general population, the rate in rescue/recovery occupations ranged from 5% to 32%, with the highest rate reported in search and rescue personnel (25%), firefighters (21%), and workers with no prior training for facing disaster. War is one of the most intense stressors known to man. Armed forces have a higher prevalence of depression, anxiety disorders, alcohol abuse and PTSD. High-risk children who have been abused or experienced natural disasters may have an even higher prevalence of PTSD than adults.Female gender, previous psychiatric problem, intensity and nature of exposure to the traumatic event, and lack of social support are known risk factors for work-related PTSD. Working with severely ill patients, journalists and their families, and audiences who witness serious trauma and war at higher risk of PTSD.The intensity of trauma, pre-trauma demographic variables, neuroticism and temperament traits are the best predictors of the severity of PTSD symptoms. About 84% of those suffering from PTSD may have comorbid conditions including alcohol or drug abuse; feeling shame, despair and hopeless; physical symptoms; employment problems; divorce; and violence which make life harder. PTSD may contribute to the development of many other disorders such as anxiety disorders, major depressive disorder, substance abuse/dependency disorders, alcohol abuse/dependence, conduct disorder, and mania. It causes serious problems, thus its early diagnosis and appropriate treatment are of paramount importance. PMID:23022845

    2005-01-01

    In the past ten years, there has been increasing recognition that children who have been exposed to traumatic events can, like traumaexposed adults, develop post-traumatic stress disorder (PTSD). Practitioners therefore need to be able to recognise and treat post-traumatic stress reactions in children. However, the direct application of adult diagnostic criteria for PTSD can result in the misdiagnosis of post-traumatic stress reactions in children, while research has only recently begun to investigate the effectiveness of different treatments for children with PTSD. This article discusses issues regarding the assessment and diagnosis of post-traumatic stress reactions in children at different developmental stages, considers neurobiological, cognitive and other factors that are theorized to increase the risk of PTSD in trauma-exposed children, and evaluates current psychotherapeutic and pharmacotherapeutic treatments for childhood PTSD. The need for more systematic research on the management of PTSD in children is noted. PMID:16633528

  11. Post-operative pulmonary complications after thoracotomy

    PubMed Central

    Sengupta, Saikat

    2015-01-01

    Pulmonary complications are a major cause of morbidity and mortality in the post-operative period after thoracotomy. The type of complications and the severity of complications depend on the type of thoracic surgery that has been performed as well as on the patient's pre-operative medical status. Risk stratification can help in predicting the possibility of the post-operative complications. Certain airway complications are more prone to develop with thoracic surgery. Vocal cord injuries, bronchopleural fistulae, pulmonary emboli and post-thoracic surgery non-cardiogenic pulmonary oedema are some of the unique complications that occur in this subset of patients. The major pulmonary complications such as atelectasis, bronchospasm and pneumonia can lead to respiratory failure. This review was compiled after a search for search terms within ‘post-operative pulmonary complications after thoracic surgery and thoracotomy’ on search engines including PubMed and standard text references on the subject from 2000 to 2015.

  12. Post retention: the effect of sequence of post-space preparation, cementation time, and different sealers.

    PubMed

    2001-12-01

    Many endodontic sealers contain constituents that have been shown to inhibit the polymerization of resin cements. This may be important when prefabricated posts are cemented at the same appointment as root canal obturation. This study evaluated the effects of cementing posts with a resin cement immediately or at a delayed time period after obturation using Roth's 801 Elite Grade or AH26 sealer cements. The contribution of mechanical post-space preparation was also assessed as a critical variable. One hundred twenty extracted canines were randomly divided into eight experimental groups. The variables evaluated were the order of post preparation (either before or after obturation), the type of sealer used, and the time of post cementation. All teeth received a stainless steel #6 Parapost XP cemented with a resin cement, Panavia 21. Each experimental group underwent tensile testing for retention using an Instron universal testing machine. For both sealers posts cemented in teeth in which the canal was obturated before post-space preparation and thus had sealer-contaminated dentin removed by the space preparation procedure had significantly higher retentive values than those obturated after post-space preparation in which contaminated dentin might remain. Sealer used and time of cementation had no specific effect on retention. Achieving a clean, "freshened" dentinal surface during mechanical post-space preparation seems to be a critical variable for post retention when a resin cement is used. PMID:11771587

  19. Evaluation of post-surface conditioning to improve interfacial adhesion in post-core restorations

    PubMed Central

    Sumitha, Mylswamy; Kothandaraman, Rajkumar; Sekar, Mahalaxmi

    2011-01-01

    Aim: To examine the influence of different post-surface treatments on the interfacial strength between epoxy resin-based fiber posts and methacrylate-based resin composites that are employed as core build-up materials. Materials and Methods: Forty clear posts were divided into four groups of 10 each. The different surface treatments used were etching with alkaline potassium permanganate, 10% hydrogen peroxide, 37% phosphoric acid, and silanization alone. After etching and thorough rinsing, a single layer of silane was applied to the post surface. Then the post was placed in a rectangular plastic matrix and core bulid-up was done using Multi Core, a dual cured composite resin. A slab of uniform thickness, with the post in the center and the core build-up composite on either side was created. The specimens were cut so as to obtain microtensile sticks that were loaded in tension at a cross-head speed of 1 mm/min until failure. The statistical analysis was performed using two-way ANOVA and the paired T test for post-hoc comparisons. Results: The results achieved with potassium permanganate had a significant influence on microtensile interfacial bond strength values with the tested material. Conclusion: Surface chemical treatments of the resin phase of fiber posts enhance the silanization efficiency of the quartz fiber phase, so that the adhesion in the post/core unit may be considered as a net sum of chemical and micromechanical retention.

    Efforts to mathematically model the Earth's post-glacial rebound, or, in general, long-term planetary-scale viscoelastic deformations, have been ongoing for several decades. Unfortunately, research in the post-glacial rebound community has not been characterized by much exchange of knowledge. Groups around the world have developed their code independently, sometimes with profoundly different approaches, occasionally leading to inconsistent results [e.g., Boschi et al., 1999]. Postglacial Rebound Calculator (TABOO) is a post-glacial rebound software that is being made freely available (through Samizdat Press at http://samizdat.mines.edu/taboo/)in the hope that it might become a common reference for all post-glacial rebound researchers. TABOO is portable and has been tested on Unix, Linux, and Windows systems; all it requires is a Fortran90 compiler supporting quadruple precision. The software is easy to use. It comes with a detailed guide that can work as a quick reference cookbook, and it is also accompanied by a textbook, The Theory Behind TABOO, collecting the most significant theoretical results from post-glacial rebound literature. TABOO is not a ``black-box,'' although it may easily be used as such. The entire source code is provided and should be easy to understand for intermediate-level Fortran programmers.

  1. Photomechanical investigations on post endodontically rehabilitated teeth.

    PubMed

    Kishen, A; Asundi, A

    2002-04-01

    An investigation of the stress distribution patterns in post-core restored teeth and the behavior of dentin material to fracture propagation was conducted using experimental techniques such as digital photoelasticity (on photoelastic models), mechanical testing and scanning electron microscopy (SEM) (on extracted teeth). Digital photoelastic experiments showed that endodontic post-core restoration resulted in regions of high tensile stress and of stress concentrations in the remaining dentin structure. It was observed from mechanical testing that the fracture resistance in post-core restored teeth is significantly lower (p<0.0001) than that in intact tooth. There was a significant correspondence between the plane of stress concentrations identified in the photoelastic models and in those of the plane of fracture exhibited by the rehabilitated tooth specimens. While the fracture of post-core rehabilitated teeth was consistent, that of control teeth was not as distinct. The SEM highlighted varying dentin response to fracture propagation at the inner core and the outer regions. The fractographs showed brittle and ductile response to fracture propagation in the outer and inner core dentin, respectively. These photomechanical studies highlighted that the stress concentrations, high tensile stress and loss of inner ductile dentin associated with post endodontic rehabilitation diminished their resistance to fracture.

    2015-05-01

    The future of command post computing demands an innovative new solution to address a variety of challenging operational needs. The Command Post of the Future is the Army's primary command and control decision support system, providing situational awareness and collaborative tools for tactical decision making, planning, and execution management from Corps to Company level. However, as the U.S. Army moves towards a lightweight, fully networked battalion, disconnected operations, thin client architecture and mobile computing become increasingly essential. The Command Post of the Future is not designed to support these challenges in the coming decade. Therefore, research into a hybrid blend of technologies is in progress to address these issues. This research focuses on a new command and control system utilizing the rich collaboration framework afforded by Command Post of the Future coupled with a new user interface consisting of a variety of innovative workspace designs. This new system is called Tactical Applications. This paper details a brief history of command post computing, presents the challenges facing the modern Army, and explores the concepts under consideration for Tactical Applications that meet these challenges in a variety of innovative ways.

    The present study tested a hypothesis that early identification of injury severity with quantitative magnetic resonance imaging (MRI) provides biomarkers for predicting increased seizure susceptibility and epileptogenesis after traumatic brain injury (TBI). TBI was induced by lateral fluid percussion injury (FPI) in adult rats. Quantitative T2, T1ρ, and diffusion were assessed with MRI at 9 days, 23 days, or 2 months post-TBI in the perilesional cortex, thalamus, and hippocampus. Seizure susceptibility was assessed at 12 months after TBI using the pentylenetetrazol seizure-susceptibility test. At 9 and 23 days post-TBI, a change in T1ρ of the perilesional cortex showed the greatest predictive value for increased seizure susceptibility at 12 months post-TBI [area under the curve (AUC), 0.929 and 0.952, respectively; p<0.01]. At 2 months post-TBI, Dav in the thalamus was the best of the biomarkers analyzed (AUC, 0.988; p<0.05). The highest predictive value of all biomarkers was achieved by combining the measurement of Dav in the perilesional cortex and the thalamus at 2 months post-TBI (AUC, 1.000; p<0.01). Our results provide proof-of-concept evidence that clinically relevant MRI biomarkers predict increased seizure susceptibility after experimental TBI.

    People tend to slow down after they make an error. This phenomenon, generally referred to as post-error slowing, has been hypothesized to reflect perceptual distraction, time wasted on irrelevant processes, an a priori bias against the response made in error, increased variability in a priori bias, or an increase in response caution. Although the response caution interpretation has dominated the empirical literature, little research has attempted to test this interpretation in the context of a formal process model. Here, we used the drift diffusion model to isolate and identify the psychological processes responsible for post-error slowing. In a very large lexical decision data set, we found that post-error slowing was associated with an increase in response caution and-to a lesser extent-a change in response bias. In the present data set, we found no evidence that post-error slowing is caused by perceptual distraction or time wasted on irrelevant processes. These results support a response-monitoring account of post-error slowing. PMID:22105857

  7. Adolf Hitler had post-encephalitic Parkinsonism.

    Adolf Hitler had Parkinson symptoms in 1934, at age 45 years. He may have had transient symptoms in 1923, at age 34 years. Young-onset parkinsonism, during the 1920s, favored a diagnosis of post-encephalitic rather than idiopathic parkinsonism. Hitler had oculogyric crises, phenomena only associated with post-encephalitic parkinsonism. In addition, he had dystonic facial spasms, palilalia and a sleep disorder, phenomena more likely to be associated with post-encephalitic than idiopathic parkinsonism. In November 1918, at age 29 years, Hitler may have had von Economo's encephalitis, while he was a patient in a hospital, recovering from poison gas. This paper looks at the possible relationship of von Economo's encephalitis to Hitler's asocial behavior; his obsessions and compulsions, his cruelty and rages. The influence of Hitler's parkinsonism on his conduct during World War II is discussed. PMID:18591024

    Non-invasive aspergillosis in immunocompetent individuals subsequent to post endodontic treatment can involve the maxillary antrum. An early and accurate diagnosis will aid in prompt and effective treatment. A 35 year old female patient reported with a painful nasomaxillary swelling. Previous records revealed the failure of the endodontic treatment of maxillary left second premolar which was subsequently extracted. Root piece was accidently left behind which resulted in a painful nasomaxillary swelling. The extraction socket was curetted and tissue was sent for histopathological examination, which revealed abundant septate fungal hyphae with numerous spores characteristic of Aspergillus. The patient showed marked improvement in the symptoms with systemic itraconazole at 3 months follow up and complete resolution occurred within 6 months. Inclusion of aspergilloma infections in the differential diagnosis is advocated when patients present with post-endodontic nasomaxillary swelling. Key words:Aspergillosis, fungal sinusitis, post root canal treatment. PMID:26535103

  9. TRIMPWR: A post processor for TRIMHX

    SciTech Connect

    Trumble, E.F.

    1989-11-01

    The TRIMPWR code has been developed as a post processor for TRIMHX (transient 3D diffusion code) in support of the reactor limits program. TRIMPWR is designed to produce JOSHUA files containing: core power as a function of time, assembly power by hex as a function of time, assembly power post peaking as a function of time, and axial power shapes for each assembly as a function of time (formatted for use by the FLOWTRAN code) from the output of a TRIMHX run. In an attempt to simplify the reactor limits process by reducing the number of assemblies which must be run through FLOWTRAN, TRIMPWR also sorts the assemblies by the product of the power post peaking and the maximum normalized axial power density for each assembly. This follows from the assumption that those assemblies having the maximum value of this product will have the most restrictive limits.

    This study aimed to describe the family experiences post-infarction. Qualitative, descriptive and exploratory research, carried out with six families of post-infarction patients. Data collection was conducted in families' homes, in the period of February to May of 2012, through observation and interviews with the family. The software Atlas Ti 6.2 was used to code the interviews and the data were explored with thematic analysis. Two categories emerged "Difficult times": immediate consequence of acute myocardial infarction for the families; and "We reeducate ourselves--we can adapt ourselves": current experience of families. The immediate post-infarction experience is permeated by several feelings, with the need for families to adapt to fit into the needs. The current experience shows changes in families due to the disease. The family is the main responsible for the care giving, although Nursing should exchange and share knowledge. PMID:24344600

    2015-12-01

    In our recent search for post-AGB stars in the Magellanic Clouds, we discovered a new class of low-luminosity, low-metallicity, dusty, evolved objects. These objects have dust excesses, stellar parameters and spectral energy distributions similar to those of dusty post-Asymptotic Giant Branch (post-AGB) stars. However, they have lower luminosities and hence smaller masses. We suggest that they have evolved off the Red Giant Branch (RGB) instead of the AGB as a result of binary interaction. Galactic counterparts are not known due to the poorly constrained distances of dusty post-AGB-like objects in the Galaxy. Here, we present the first observational evidence these new dusty, low-luminosity "post-RGB" objects and we aim to place these objects in an evolutionary context.

    Post-hypoxic myoclonus is a form of myoclonus frequently caused by cardiac arrest. Development of an animal model may facilitate understanding of the condition and its treatments. We describe an animal model of post-hypoxic myoclonus developed in our laboratory through cardiac arrest, initially induced by chemical and later by mechanical obstruction of major cardiac vessels. These animals respond to valproate, clonazepam and 5-hydroxytrytophan reminiscent of its human counterpart. We review their behavioral, pharmacological and neuropathological features. Therapy developed for myoclonus in this model may be helpful for myoclonus from other etiologies such as corticobasal degeneration, Lewy-body disorders, Creutzfeld-Jacob disease, Alzheimer's disease.

    2003-06-24

    Generator stator cores are constructed by stacking many layers of magnetic laminations. Ventilation ducts may be inserted between these layers by inserting spacers into the core stack. The ventilation ducts allow for the passage of cooling gas through the core during operation. The spacers or spacer posts are positioned between groups of the magnetic laminations to define the ventilation ducts. The spacer posts are secured with longitudinal axes thereof substantially parallel to the core axis. With this structure, core tightness can be assured while maximizing ventilation duct cross section for gas flow and minimizing magnetic loss in the spacers.

    A non-linear filter for image post processing based on the feedforward Neural Network topology is presented. This study was undertaken to investigate the usefulness of "smart" filters in image post processing. The filter has shown to be useful in recovering high frequencies, such as those lost during the JPEG compression-decompression process. The filtered images have a higher signal to noise ratio, and a higher perceived image quality. Simulation studies comparing the proposed filter with the optimum mean square non-linear filter, showing examples of the high frequency recovery, and the statistical properties of the filter are given,

    Aiming toward the rectification of fiber grade PET waste accumulation as well as recycling and providing a technically viable route leading to preservation of the natural resources and environment, the post consumed polyester clothes were chemically recycled. Post consumed polyester clothes were recycled into bis(2-hydroxyethyl) terephthalate (BHET) monomer in the presence of ethylene glycol as depolymerising agent and zinc acetate as catalyst. Depolymerized product was characterized by chemical as well as analytical techniques. The fiber grade PET was eventually converted into BHET monomer with nearly 90% yield by employing 1% catalyst concentration and at optimum temperature of 180°C without mechanical input of stirring condition.

  16. Post-combustion reactions and modeling

    NASA Astrophysics Data System (ADS)

    Story, Scott R.

    Owing to the presence of carbon, oxygen and hydrogen in many iron and steelmaking processes, vast quantities of combustible gases rich in CO along with Hsb2 are often created. To take advantage this potential chemical energy, extra amounts of oxygen may be supplied to the process in order to combust these species, through a practice known as post combustion. Effective post combustion is important in many steelmaking processes. Post combustion is strongly affected by fluid flow. However, in the presence of carbon and iron at high temperatures reactions known as "de-postcombustion" occur where carbon or Fe is oxidised. These reactions depend on kinetics and fluid flow. To address the lack of information at high temperature, the kinetics of carbon oxidation by COsb2 and Hsb2O has been studied at temperatures between 1300sp C and 1500sp C. At 1500sp C, the graphite-Hsb2O reaction was found to occur at a similar rate to the graphite-COsb2 reaction. The overriding importance of internal pore structure was demonstrated in the results, particularly as it develops in the reacted layer during the course of the reaction. Such changes are believed to be responsible for the continuous rate increase observed in non-porous glassy carbon and the consistently higher rates measured in graphite than in coke at high temperatures. The results of this work have also been used to clarify the role of the gas-carbon reaction in the kinetics of FeO reduction in bath smelting slags by solid carbon. Under high stirring conditions in the slag it has been found that the gas-carbon reaction may play a significant role, particularly when coke is the carbonaceous material. The second component of this study was directed toward understanding the effect of fluid flow on post combustion in the electric arc furnace (EAF). In particular the objective was to determine if computational fluid dynamics (CFD) can be a useful tool for optimising post combustion. The post combustion degree (PCD) was found to be affected by three main factors, namely the rate of de-postcombustion at the surface, the efficiency of combustion in the lance jet and the degree of recirculation of gases in the furnace. Owing to assumptions made in the de-postcombustion model, the lance flowrate had little effect on the predicted values of PCD. This finding revealed the need to better characterise the relationship between jet momentum and de-postcombustion efficiency. Low combustion efficiencies will adversely affect post combustion efficiency. Increased recirculation of gases in the furnace was also found to reduce the post combustion degree.

  1. Influence of prefabricated post dimensions on restored maxillary central incisors.

    2007-02-01

    The aim of this study was to test the following hypothesis: biomechanical performance (fracture strength and stress distribution) of restored teeth is less sensitive to post diameter and post length when using glass fibre posts than when using stainless steel posts. First, an experimental fracture strength test was performed on 80 extracted human maxillary central incisors. Teeth were decoronated, treated endodontically and restored (40 with glass fibre posts and 40 with stainless steel posts), and the length and diameter of the posts varied uniformly. Failure loads were recorded and results were compared using an ancova analysis. Secondly, the finite element technique was used to develop a model of the restored tooth. The post diameter had a significant effect on the biomechanical performance of teeth restored with stainless steel posts. Lower failure loads were found as post diameter increased. However, the post diameter of those teeth restored with glass fibre posts, and the post length for both post systems under consideration, did not affect the biomechanical performance of restored teeth to a significant degree. The stress distributions predicted by the developed model corroborated these findings, confirmed the assumed hypothesis, and permitted the proposal of the use of glass fibre posts to achieve a restorative technique that is less sensitive to post dimensions, and thus more robust.

  13. Post stapedotomy aviation: A changing scenario.

    PubMed

    Rajguru, Renu

    2014-01-01

    Aeromedical implications of stapedotomy like rapid barometric changes and G forces are generally thought to put an end to the aviation career of an aviator. Aviation industry has grown tremendously in the last few decades, and aviation now is not only occupational but also recreational. The Indian Military Aviation rules state that, "Stapedectomy cases will be assessed permanently unfit for flying duties. These cases will be cautioned against flying in an unpressurised aircraft." The basis of this is the aeromedical concerns associated with stapedotomy as clinical conditions which are of minor significance on the ground may become aggravated in the air. With an ever expanding civil and military aviation industry, the number of aviators who have undergone stapedotomy has also increased. Though grounding the aircrew is the safest option, but if medical certification is denied to all, then the majority who can fly safely will also be excluded, thus denying the organization of its trained resources. This paper discusses post otosclerosis and post stapedotomy aeromedical concerns, reviews existing literature concerning post stapedotomy aviation and various post stapedotomy aviation policies.

  16. Post Rift Thermal Evolution of Extended Lithosphere

    NASA Astrophysics Data System (ADS)

    Cardoso, R. R.; Hamza, V. M.

    2009-12-01

    An improved thermal model of the lithosphere extension is proposed and its influence in the petroleum system in sedimentary basins examined. The new model assumes existence of time dependent variation in the lithosphere thickness during the post-rift period, which was not take account in the formulation of the Mackenzie model (1978). In the present work we assume that the asymptotic growth of the lithosphere thickness, during the post-rift period, may be represented by an asymptotic relation of the type: L(t)=(L/?)+(L-L/?)erf(?*t) where L(t) is lithospheric thickness at post-rift time t, ? the stretching factor as defined in the McKenzie model, erf the error function and ? a suitable scaling constant. According to the above equation the syn-rift value of L is (L/?). For large times the thickness of the lithosphere approaches asymptotically the pre-rift value of L. The value of ? can be determined by calculating the time necessary for the stretched lithosphere (L/?) to return to original thickness. The results of numerical simulations indicate that the heat flux derived from the new model is substantially lower than the values predicted by the McKenzie model (see Figure 1). The new model has been calibrated using available information on evolution of thermal maturity indices for the Santos Basin, situated in the offshore area of southeast Brazil. Heat flow variations during the post stretch period, for the case in which the stretching factor is 2.5.

  3. Microgyroscope with Vibrating Post as Rotation Transducer

    NASA Technical Reports Server (NTRS)

    Tang, Tony K.; Gutierrez, Roman

    2003-01-01

    The figure depicts a micromachined silicon vibratory gyroscope that senses rotation about its z axis. The rotation-sensitive vibratory element is a post oriented (when at equilibrium) along the z axis and suspended at its base by thin, flexible silicon bands oriented along the x and y axes, respectively. Unlike in the vibratory microgyroscopes described in the immediately preceding article ["Cloverleaf Vibratory Microgyroscope With Integrated Post" (NPO-20688)] and other previous articles in NASA Tech Briefs, the rotation-sensitive vibratory element does not include a cloverleaf-shaped structure that lies (when at equilibrium) in the x-y plane. As in the cases of the previously reported vibratory microgyroscopes, vibrations of the rotation-sensitive vibratory element are excited electrostatically, the vibrations are measured by use of capacitive proximity sensors, and the rate of rotation along the axis of sensitivity is deduced from the effect of the Coriolis force upon the vibrations. To create electrodes for electrostatic excitation and capacitive sensing of vibrations, portions of the facing surfaces of the post and of the four stationary members that surround the post are rendered electrically conductive; this can be accomplished by either depositing metal films or else doping the silicon in the affected areas.

  7. Video segmentation for post-production

    NASA Astrophysics Data System (ADS)

    Wills, Ciaran

    2001-12-01

    Specialist post-production is an industry that has much to gain from the application of content-based video analysis techniques. However the types of material handled in specialist post-production, such as television commercials, pop music videos and special effects are quite different in nature from the typical broadcast material which many video analysis techniques are designed to work with; shots are short and highly dynamic, and the transitions are often novel or ambiguous. We address the problem of scene change detection and develop a new algorithm which tackles some of the common aspects of post-production material that cause difficulties for past algorithms, such as illumination changes and jump cuts. Operating in the compressed domain on Motion JPEG compressed video, our algorithm detects cuts and fades by analyzing each JPEG macroblock in the context of its temporal and spatial neighbors. Analyzing the DCT coefficients directly we can extract the mean color of a block and an approximate detail level. We can also perform an approximated cross-correlation between two blocks. The algorithm is part of a set of tools being developed to work with an automated asset management system designed specifically for use in post-production facilities.

  4. Post-natal imprinting: evidence from marsupials

    PubMed Central

    Stringer, J M; Pask, A J; Shaw, G; Renfree, M B

    2014-01-01

    Genomic imprinting has been identified in therian (eutherian and marsupial) mammals but not in prototherian (monotreme) mammals. Imprinting has an important role in optimising pre-natal nutrition and growth, and most imprinted genes are expressed and imprinted in the placenta and developing fetus. In marsupials, however, the placental attachment is short-lived, and most growth and development occurs post-natally, supported by a changing milk composition tailor-made for each stage of development. Therefore there is a much greater demand on marsupial females during post-natal lactation than during pre-natal placentation, so there may be greater selection for genomic imprinting in the mammary gland than in the short-lived placenta. Recent studies in the tammar wallaby confirm the presence of genomic imprinting in nutrient-regulatory genes in the adult mammary gland. This suggests that imprinting may influence infant post-natal growth via the mammary gland as it does pre-natally via the placenta. Similarly, an increasing number of imprinted genes have been implicated in regulating feeding and nurturing behaviour in both the adult and the developing neonate/offspring in mice. Together these studies provide evidence that genomic imprinting is critical for regulating growth and subsequently the survival of offspring not only pre-natally but also post-natally. PMID:24595366

  7. Is adhesive cementation of endodontic posts necessary?

    PubMed

    Naumann, Michael; Sterzenbach, Guido; Rosentritt, Martin; Beuer, Florian; Frankenberger, Roland

    2008-08-01

    Recently, the appropriate, durable bond of adhesive systems and composite resin cements to retain endodontic posts was challenged. The question arises whether it would be possible to place glass fiber posts in a less technique sensitive conventional nonadhesive approach. The influence of nonadhesive, self-adhesive, and etch-and-rinse systems on load capability of postendodontic restorations was studied. Human maxillary central incisors were divided into 4 groups (n = 10). Teeth were endodontically treated and restored by using glass fiber posts luted with different cements/composite resin combinations: (1) RelyX Unicem (3M ESPE, Seefeld, Germany)/Clearfil Core (Kuraray Europe, Duesseldorf, Germany), (2) RelyX Unicem/LuxaCore, (3) zinc phosphate cement/Clearfil, and (4) LuxaCore (DMG, Hamburg, Germany)/Clearfil. A 2 mm-ferrule preparation was performed. All specimens received adhesively luted all-ceramic crowns and were exposed to thermal cycling and mechanical loading before subsequent static loading. Significant differences between the experimental groups regarding load capability and fracture patterns were observed. The conventional non-adhesive post cementation is less reliable to withstand simulated functional forces compared to adhesive approaches. PMID:18634936

    The evolution and current position of post-Keynesian economic theory are examined. The theory is based on Keynes' exposition of effective demand in a monetary production economy determining the level of employment, rather than through supply and demand in the "real" and "monetary" sectors determining the level of real output.

  4. Delayed post-conditioning reduces post-ischemic glutamate level and improves protein synthesis in brain.

    In the clinic delayed post-conditioning would represent an attractive strategy for the survival of vulnerable neurons after an ischemic event. In this paper we studied the impact of ischemia and delayed post-conditioning on blood and brain tissue concentrations of glutamate and protein synthesis. We designed two groups of animals for analysis of brain tissues and blood after global ischemia and post-conditioning, and one for analysis of blood glutamate after transient focal ischemia. Our results showed elevated blood glutamate in two models of transient brain ischemia and decreases in blood glutamate to control in the first 20min of post-conditioning recirculation followed by a consecutive drop of about 20.5% on the first day. Similarly, we recorded reduced protein synthesis in hippocampus and cortex 2 and 3days after ischemia. However, increased glutamate was registered only in the hippocampus. Post-conditioning improves protein synthesis in CA1 and dentate gyrus and, surprisingly, leads to 50% reduction in glutamate in whole hippocampus and cortex. In conclusion, ischemia leads to meaningful elevation of blood and tissue glutamate. Post-conditioning activates mechanisms resulting in rapid elimination of glutamate from brain tissue and/or in the circulatory system that could otherwise impede brain-to-blood glutamate efflux mechanisms. Moreover, post-conditioning induces protein synthesis renewing in ischemia affected tissues that could also contribute to elimination of excitotoxicity. In addition, the potential of glutamate for monitoring the progress of ischemia and efficacy of therapy was shown. PMID:23454191

    2015-01-01

    A novel stable crystal structure is discovered in a variety of A B O3,A B F3 , and A2O3 compounds, via the use of first principles. This novel structure appears under hydrostatic pressure, and can be considered to be a post-post-perovskite phase. It provides a successful solution to experimental puzzles in important systems and is characterized by one-dimensional channels linked by a group of two via edge-sharing oxygen/fluorine octahedra. Such organization automatically results in anisotropic elastic properties and new magnetic arrangements. Depending on the system of choice, this post-post-perovskite structure also possesses electronic band gaps ranging from zero to ≃10 eV being direct or indirect in nature.

    Post-shock temperature is an important quantity in shock physics experiments for constraining the dynamic equations of state of materials. A high-speed, infrared, multi-wavelength pyrometer has been developed at Los Alamos National Laboratory (LANL) for measurements in the temperature range from 400 to 1200 K. With customized front end optics, permitting concurrent VISAR measurements in the same optical path, validation experiments on aluminum have been conducted at the new Shock Compression Laboratory at Harvard University. Under <1 millitorr vacuum, a post-shock temperature of 495 K 30 K was recorded from a polished free surface of aluminum 2024-T4 subject to a peak shock pressure of 34.80.8 GPa, in excellent agreement with the equation of state and previous experiments.

  8. Ex Post Facto Monte Carlo Variance Reduction

    SciTech Connect

    Booth, Thomas E.

    2004-11-15

    The variance in Monte Carlo particle transport calculations is often dominated by a few particles whose importance increases manyfold on a single transport step. This paper describes a novel variance reduction method that uses a large importance change as a trigger to resample the offending transport step. That is, the method is employed only after (ex post facto) a random walk attempts a transport step that would otherwise introduce a large variance in the calculation.Improvements in two Monte Carlo transport calculations are demonstrated empirically using an ex post facto method. First, the method is shown to reduce the variance in a penetration problem with a cross-section window. Second, the method empirically appears to modify a point detector estimator from an infinite variance estimator to a finite variance estimator.

    The Long Range Video Observation Post (LRVOP) Project is a cooperative effort between the US and a Middle Eastern country to develop an improved version of their current video observation post. This project is part of a larger effort to cooperatively develop anti-terrorist technology. This particular equipment is required to facilitate the recording and identification of humans at a range of 1000 meters in day-light and 500 meters at night. The project objective was to take advantage of recent advances in camera technology, recorders, and image processing to provide an significant increase in performance with only a minimum increase in size, weight, and cost. The goal of the project was to convert the users general needs and desires into specific requirements that could be bid on by several companies. This paper covers the specific performance requirements, generally describe the components that might be used, and concentrate on describing the more difficult issues and technical challenges.

  10. Post-Translational Modifications of TRP Channels

    PubMed Central

    Voolstra, Olaf; Huber, Armin

    2014-01-01

    Transient receptor potential (TRP) channels constitute an ancient family of cation channels that have been found in many eukaryotic organisms from yeast to human. TRP channels exert a multitude of physiological functions ranging from Ca2+ homeostasis in the kidney to pain reception and vision. These channels are activated by a wide range of stimuli and undergo covalent post-translational modifications that affect and modulate their subcellular targeting, their biophysical properties, or channel gating. These modifications include N-linked glycosylation, protein phosphorylation, and covalent attachment of chemicals that reversibly bind to specific cysteine residues. The latter modification represents an unusual activation mechanism of ligand-gated ion channels that is in contrast to the lock-and-key paradigm of receptor activation by its agonists. In this review, we summarize the post-translational modifications identified on TRP channels and, when available, explain their physiological role. PMID:24717323

    Verellen, Rebecca M; Cavazos, Jose E

    2014-01-01

    Post-traumatic seizures (PTS) and post-traumatic epilepsy (PTE) are complications from traumatic brain injury (TBI). PTE refers to recurrent and unprovoked PTS that occur at least 1 week after TBI. Seizures during the first week after TBI are considered provoked, an acute complication from head injury, while seizures occurring 1 week after TBI are considered a manifestation of PTE and if only a single seizure occurs it is known as late PTS. EEG and neuroimaging help in the diagnosis of PTE. Predictors for PTE include TBI severity, presence of intracranial bleeding and early PTS. Several clinical trials have demonstrated that antiepileptic drugs are effective in reducing the frequency of acute PTS, but do not appear to alter the natural history of late PTS or PTE.

    Analysis of in situ collected spectral reflectance data from a dormant or senescent grass canopy showed a direct relationship existed between spectral reflectance and biomass for the 0.50-0.80 micron spectral region. The data, collected four weeks after the end of the growing season, indicated that post senescent remote sensing of grass canopy biomass is possible and helps to elucidate the spectral contribution of recently dead vegetation in mixed live/dead canopy situations.

    A case of post-traumatic syringomyelia developing two years after spinal cord injury is presented. The patient was treated with the placement of a thecoperitoneal shunt incorporating a low pressure valve. Response was excellent with restoration of neurological function and almost complete collapse of the cavity at one year follow up. The rationale of this form of treatment is discussed in the light of recent evidence concerning the pathogenesis of the condition. Images PMID:8006663

    Background Structural factors contributing to the development of post-infarction ventricular tachycardia (VT) are unclear. The purpose of this study was to analyze infarct architecture and electrogram characteristics in patients with and without inducible VT and to identify correlates of post-infarction VT. Methods and Results Twenty-four post-infarction patients (median age 64 [53,70] years) were referred for radiofrequency catheter ablation of VT (n=12) or frequent symptomatic premature ventricular contractions (PVCs, n=12). Delayed-enhanced magnetic resonance imaging (DE-MRI) was obtained prior to ablation. Electroanatomical mapping was performed and scar area and electrogram characteristics of the scar tissue were compared in patients with and without inducible VT. The median ejection fraction in subjects with and without inducible VT was 27% [22,43] and 43% [40,47], respectively (p=0.085). Subendocardial infarct area determined by DE-MRI was larger in patients with inducible VT (43 [38,62] cm2) than those who were non-inducible (8 [4,11] cm2, p=0.002), and unipolar and bipolar voltages on electroanatomical maps were significantly lower in inducible patients (both p<0.05). An infarct volume of >14% identified 11 of 12 patients with inducible VT (AUC 0.94, p=0.007). On electroanatomical mapping, distinct sites with isolated potentials (IPs) were more prevalent in inducible than noninducible patients (13.2% vs. 1.1% of points within scar; p<0.001). The number of inducible VTs correlated with the number of distinct sites with IPs (R=0.87, p<0.0001). Conclusions Scar tissue in post-infarction patients with inducible VT shows quantitative and qualitative differences from scars in patients without inducible VT. Scar size and IPs are correlated with VT inducibility. PMID:20937722

    Post-translational modifications (PTMs) occur on nearly all proteins. Many domains within proteins are modified on multiple amino acid sidechains by diverse enzymes to create a myriad of possible protein species. How these combinations of PTMs lead to distinct biological outcomes is only beginning to be understood. This manuscript highlights several examples of combinatorial PTMs in proteins, and describes recent technological developments, which are driving our ability to understand how PTM patterns may code for biological outcomes.

    2016-02-01

    The fates of planetary systems provide unassailable insights into their formation and represent rich cross-disciplinary dynamical laboratories. Mounting observations of post-main-sequence planetary systems necessitate a complementary level of theoretical scrutiny. Here, I review the diverse dynamical processes which affect planets, asteroids, comets and pebbles as their parent stars evolve into giant branch, white dwarf and neutron stars. This reference provides a foundation for the interpretation and modelling of currently known systems and upcoming discoveries. PMID:26998326

    To explore the capture dynamics of photoexcited carriers in semiconductor quantum posts, optical pump - THz probe and time-resolved photoluminescence spectroscopy were performed. The results of the THz experiment show that after ultrafast excitation, electrons relax within a few picoseconds into the quantum posts, which are acting as efficient traps. The saturation of the quantum post states, probed by photoluminescence, was reached approximately at ten times the quantum post density in the samples. The results imply that quantum posts are posts highly attractive nanostructures for future device applications.

  3. Post-production modification of industrial enzymes.

    Minten, Inge J; Abello, Nicolas; Schooneveld-Bergmans, Margot E F; van den Berg, Marco A

    2014-01-01

    Industry has an increasing interest in the use of enzymes as environmentally friendly, highly efficient, and specific bio-catalysts. Enzymes have primarily evolved to function in aqueous environments at ambient temperature and pressure. These conditions however do not always correspond with industrial processes or applications, and only a small portion of all known enzymes are therefore suitable for industrial use. Protein engineering can sometimes be applied to convey more desirable properties to enzymes, such as increased stability, but is limited to the 20 naturally occurring amino acids or homologs thereof. Using post-production modification, which has the potential to combine desirable properties from the enzyme and the conjugated compounds, enzymes can be modified with both natural and synthetic molecules. This offers access to a myriad of possibilities for tuning the properties of enzymes. At this moment, however, the effects of post-production modification cannot yet be reliably predicted. The increasing number of applications will improve this so that the potential of this technology can be fully exploited. This review will focus on post-production modification of enzymes and its use and opportunities in industry. PMID:24903809

  4. Post Disaster Governance, Complexity and Network Theory

    Lassa, Jonatan A.

    2015-01-01

    This research aims to understand the organizational network typology of large­-scale disaster intervention in developing countries and to understand the complexity of post-­disaster intervention, through the use of network theory based on empirical data from post-­tsunami reconstruction in Aceh, Indonesia, during 2005/­2007. The findings suggest that the ‘ degrees of separation’ (or network diameter) between any two organizations in the field is 5, thus reflecting ‘small­ world’ realities and therefore making no significant difference with the real human networks, as found in previous experiments. There are also significant loops in the network reflecting the fact that some actors tend to not cooperate, which challenges post­ disaster coordination. The findings show the landscape of humanitarian actors is not randomly distributed. Many actors were connected to each other through certain hubs, while hundreds of actors make ‘scattered’ single ‘principal-­client’ links. The paper concludes that by understanding the distribution of degree, centrality, ‘degrees of separation’ and visualization of the network, authorities can improve their understanding of the realities of coordination, from macro to micro scales.

  5. Historical approaches to post-combat disorders

    PubMed Central

    Jones, Edgar

    2006-01-01

    Almost every major war in the last century involving western nations has seen combatants diagnosed with a form of post-combat disorder. Some took a psychological form (exhaustion, combat fatigue, combat stress reaction and post-traumatic stress disorder), while others were characterized by medically unexplained symptoms (soldier's heart, effort syndrome, shell shock, non-ulcer dyspepsia, effects of Agent Orange and Gulf War Syndrome). Although many of these disorders have common symptoms, the explanations attached to them showed considerable diversity often reflected in the labels themselves. These causal hypotheses ranged from the effects of climate, compressive forces released by shell explosions, side effects of vaccinations, changes in diet, toxic effects of organophosphates, oil-well fires or depleted-uranium munitions. Military history suggests that these disorders, which coexisted in the civilian population, reflected popular health fears and emerged in the gaps left by the advance of medical science. While the current Iraq conflict has yet to produce a syndrome typified by medically unexplained symptoms, it is unlikely that we have seen the last of post-combat disorders as past experience suggests that they have the capacity to catch both military planners and doctors by surprise.

  6. Pre- and post-purge technology applications

    SciTech Connect

    What do gas-to-oil heat conversions, forced draft systems, commercial installations and big chimneys have in common? At times, they all pose problems that can be helped by a pre- and post-purge burner control. With a purge system, the burner becomes its own venter. Before ignition, the blower starts circulating air for a pre-purge cycle (typically 10-30 seconds), to make starting easier and avoid lockouts due to poor draft conditions. Upon burner shutdown, airflow continues for a post-purge period (30 seconds to 5 minutes), to clear the chamber of combustion gases and prevent a backdraft from sucking fumes into the building. To create a purging system, the technician has typically had to assemble a jury-rigged system of relays and timers or spend $75 for a relay kit. To fill this need at much less expense, a new microprocessor-based primary control with pre-and post-purge capabilities built in is described. Early feedback from the field shows that dealer installation people are using this control to tackle a variety of different problems, depending on what they run into and what`s most important to solve for their customers. Each model 60200-02S control is pre-set at the factory with one of several timing patterns.

  7. AGR-1 Post Irradiation Examination Final Report

    SciTech Connect

    Demkowicz, Paul Andrew

    2015-08-01

    The post-irradiation examination (PIE) of the Advanced Gas Reactor (AGR)-1 experiment was a multi-year, collaborative effort between Idaho National Laboratory (INL) and Oak Ridge National Laboratory (ORNL) to study the performance of UCO (uranium carbide, uranium oxide) tristructural isotropic (TRISO) coated particle fuel fabricated in the U.S. and irradiated at the Advanced Test Reactor at INL to a peak burnup of 19.6% fissions per initial metal atom. This work involved a broad array of experiments and analyses to evaluate the level of fission product retention by the fuel particles and compacts (both during irradiation and during post-irradiation heating tests to simulate reactor accident conditions), investigate the kernel and coating layer morphology evolution and the causes of coating failure, and explore the migration of fission products through the coating layers. The results have generally confirmed the excellent performance of the AGR-1 fuel, first indicated during the irradiation by the observation of zero TRISO coated particle failures out of 298,000 particles in the experiment. Overall release of fission products was determined by PIE to have been relatively low during the irradiation. A significant finding was the extremely low levels of cesium released through intact coatings. This was true both during the irradiation and during post-irradiation heating tests to temperatures as high as 1800°C. Post-irradiation safety test fuel performance was generally excellent. Silver release from the particles and compacts during irradiation was often very high. Extensive microanalysis of fuel particles was performed after irradiation and after high-temperature safety testing. The results of particle microanalysis indicate that the UCO fuel is effective at controlling the oxygen partial pressure within the particle and limiting kernel migration. Post-irradiation examination has provided the final body of data that speaks to the quality of the AGR-1 fuel, building on the as-fabricated fuel characterization and irradiation data. In addition to the extensive volume of results generated, the work also resulted in a number of novel analysis techniques and lessons learned that are being applied to the examination of fuel from subsequent TRISO fuel irradiations. This report provides a summary of the results obtained as part of the AGR-1 PIE campaign over its approximately 5-year duration.

    Irradiated polyamide-1010 (PA1010) with and without heat treatment after ?-ray irradiation was compared by wide angle x-ray diffraction (WAXD), differential scanning calorimeter (DSC) and the determination of gel fractions. The results indicate that post radiation effects due to post radiation crosslinking and scissions affect physical properties. Post radiation effects restrain the formation and perfection of the planes (010), and make the crystals imperfect. Post radiation effects change the crystalline structures of polyamide-1010.

  4. Uav Application in POST - Seismic Environment

    NASA Astrophysics Data System (ADS)

    Baiocchi, V.; Dominici, D.; Mormile, M.

    2013-08-01

    On April 6, 2009, an earthquake of 6.3 magnitude struck central Italy with its epicentre near L'Aquila, at 42.3502° N, 13.3762° E. The earthquake damaged 3000 to 11 000 buildings in the medieval city of L'Aquila. Several buildings totally collapsed, 308 people were killed. The post emergency phase till now is just at its beginning step. Conventional surveying techniques using high precision total stations, GNSS receivers and laser scanners for investigations on damaged buildings are always becoming more automated, accurate and operative and even much more fast. Even if these techniques represent instruments of extreme operability there are still many evident limits on their use, especially regarding the survey of both the roofs and the facades of tall buildings or dangerous places, typical on post earthquake situations. So using micro UAVs for surveying in such particular cases, many of these problems can be easily bypassed. In fact, the present work aims on experimenting using multi-rotor micro UAVs, that will allow high quality image capturing on roofs and facades of structures in the old city center of L'Aquila. To obtain actual stereoscopic acquisitions of buildings some conditions on the geometry of acquisition have to be observed, for this reason, taking as a guideline classic flight photogrammetric, a flight planning software was developed. Accurate planning for UAVs acquisitions is very important also considering the reduced autonomy of such vehicles. This can be a strategic point if we want to use UAVs for early damage assessment and also for post event reconstruction planning.

  5. Treatment of Post-Traumatic Cognitive Impairments

    PubMed Central

    Wortzel, Hal S.; Arciniegas, David B.

    2012-01-01

    Opinion statement Cognitive impairment is a common consequence of traumatic brain injury (TBI) and a substantial source of disability. Across all levels of TBI severity, attention, processing speed, episodic memory, and executive function are most commonly affected.The differential diagnosis for posttraumatic cognitive impairments is broad, and includes emotional, behavioral, and physical problems as well as substance use disorders, medical conditions, prescribed and self-administered medications, and symptom elaboration. Thorough neuropsychiatric assessment for such problems is a pre-requisite to treatments specifically targeting cognitive impairments.First-line treatments for posttraumatic cognitive impairments are non-pharmacologic, including education, realistic expectation setting, environmental and lifestyle modifications, and cognitive rehabilitation.Pharmacotherapies for posttraumatic cognitive impairments include uncompetitive N-methyl-D-aspartate receptor (NMDA) antagonists, medications that directly or indirectly augment cerebral catecholaminergic or acetylcholinergic function, or agents with combinations of these properties.In the immediate post-injury period, treatment with uncompetitive NMDA receptor antagonists reduces duration of unconsciousness. The mechanism for this effect may involve attenuation of neurotrauma-induced glutamate-mediated excitotoxicity and/or stabilization of glutamate signaling in the injured brain.During the sub-acute or late post-injury periods, medications that augment cerebral acetylcholinergic function may improve declarative memory. Among responders to this treatment, secondary benefits on attention, processing speed, and executive function impairments as well as neuropsychiatric disturbances may be observed. During these post-injury periods, medications that augment cerebral catecholaminergic function may improve hypoarousal, processing speed, attention, and/or executive function as well as comorbid depression or apathy.When medications are used, a start-low, go-slow, but go approach is encouraged, coupled with frequent reassessment of benefits and side effects as well as monitoring for drug-drug interactions. Titration to either beneficial effect or medication intolerance should be completed before discontinuing a treatment or augmenting partial responses with additional medications. PMID:22865461

  6. Post-Traumatic Stress Symptoms and Post-Traumatic Growth: Evidence from a Longitudinal Study following an Earthquake Disaster

    PubMed Central

    Chen, Jieling; Zhou, Xiao; Zeng, Min; Wu, Xinchun

    2015-01-01

    Objective The current longitudinal study aims to examine the bidirectional relationship between post-traumatic stress symptoms (PTSS) and post-traumatic growth (PTG). Method One hundred twenty-two adults in the most severely affected area were investigated by self-report questionnaires at 12 months and 18 months after the Wenchuan Earthquake occurred in China. Results The autoregressive cross-lagged structure equation analysis revealed that PTG at 12 months post-earthquake could negatively predict PTSS at 18 months post-earthquake above and beyond PTSS stability, whereas PTSS at 12 months post-earthquake could not significantly predict subsequent PTG. Moreover, PTG at 12 months post-earthquake could predict fewer subsequent intrusions, numbing and hyper-arousal symptoms but not avoidance symptoms. Conclusion Growth can play a role in reducing long-term post-traumatic stress symptoms, and the implication of a positive perspective in post-trauma circumstance is discussed. PMID:26046912

    The purpose of this study was to compare the retention of fiber-reinforced composite (FRC) posts luted with either conventional or self-adhesive resin cement. The FRC posts and core resin were built up in bovine teeth. The posts were luted with standard etch-andrinse cement, self-etch cement, or one of two self-adhesive cements. The samples were stored in water for 1 or 14 days or subjected to thermal cycling (TC). Retention value was measured with the pull-out test using a universal testing machine. Conventional adhesive resin cement yielded significantly greater retention than self-adhesive resin cement at 1 day. No significant difference was observed in retention among the adhesive systems tested at 14 days or after TC. During the early luting stage, self-adhesive resin cement yielded lower retention value than conventional resin cement. After 14 days storage or TC, retention was comparable to that with conventional resin cement. PMID:23903651

    The activity under this grant concentrated on: (1) post-launch calibration of the HARP instrument; and (2) analysis and interpretation of the data from the HARP and other related instruments. The HARP was taken by scientists and engineers from the Hungarian Central Research Institute for Physics (CRIP) to NASA/MSFC for calibration in their plasma chamber, with partial support of this grant. This electron and ion calibration of the HARP, helped in transforming measured currents to actual flux values. The analysis and interpretation of the data, carried out jointly by our Russian and Hungarian colleagues and us, led to a number of journal publications and presentations at scientific meetings.

    Post-main sequence evolution directly affects the survival of planetary and sub-planetary mass bodies. Planets orbiting evolved stars undergo orbital evolution under the influence of tides and mass-loss, can be ejected, evaporated, and suffer multiple-body instabilities. The conditions on the planet surface are expected to be modified as well as the result of the evolution of the star. I will discuss the new limits that the theoretical studies allow us to set on the survival and habitability of planets as the star runs out of its hydrogen fuel.

    Serious complications associated with post-laparoscopic adjustable gastric band (LAGB) abdominoplasty have been reported in the medical literature. Furthermore, others have noted aesthetic problems with closure of the umbilicus due to apparatus port proximity. Currently, no clinical protocol or formal industry guidance for LAGB apparatus management during abdominoplasty is available in the medical literature. In this article, the authors describe their procedure for safe LAGB apparatus management during abdominoplasty and illustrate key surgical principles by presenting unique cases from their series of 20 patients treated with this technique.

    A 7 years old boy presenting with acute flaccid paralysis after Varicella zoster infection was diagnosed as having acute transverse myelitis on MRI. He recovered fully after treatment with intravenous corticosteroids and acyclovir. The occurrence of this condition during or following Varicella infection is uncommon. There are previously very few reported cases of post-Varicella acute transverse myelitis in which recovery started after 3 months of treatment. In this case complete recovery occurred in 2 weeks of treatment. This report emphasizes the need for Varicella zoster vaccine to prevent not only acute Varicella, but also its rare postinfectious neurologic sequelae. PMID:24906257

    Post-traumatic stress disorder is a frequently diagnosed disorder. Expert assessments of claimants with PTSD symptoms have become a common challenge for physicians in civil lawsuits. Since diagnosis of PTSD relies primarily on the patient's subjective report, this syndrome is particularly vulnerable to malingering. For this reason, it is important for physicians to try to identify individuals with true PTSD and differentiate them from those who malinger the disorder. This paper outlines the general problems and assessment strategies involved in the detection of malingering. A special focus is placed on the typical presentation of malingered PTSD symptoms.

    Results on a novel type of stellarator configuration, the Helical Post Stellarator (HPS), are presented. This configuration is different significantly from all previously known stellarators due to its unique geometrical characteristics and unique physical properties. Among those are: the magnetic field has only one toroidal period (M = 1), the plasma has an extremely low aspect ratio, A {approx} 1, and the variation of the magnetic field, B, along field lines features a helical ripple on the inside of the torus. Among the main advantages of a HPS for a fusion program are extremely compact, modular, and simple design compatible with significant rotational transform, large plasma volume, and improved particle transport characteristics.

  19. Spherical tokamaks with plasma centre-post

    NASA Astrophysics Data System (ADS)

    Ribeiro, Celso

    2013-10-01

    The metal centre-post (MCP) in tokamaks is a structure which carries the total toroidal field current and also houses the Ohmic heating solenoid in conventional or low aspect ratio (Spherical)(ST) tokamaks. The MCP and solenoid are critical components for producing the toroidal field and for the limited Ohmic flux in STs. Constraints for a ST reactor related to these limitations lead to a minimum plasma aspect ratio of 1.4 which reduces the benefit of operation at higher betas in a more compact ST reactor. Replacing the MCP is of great interest for reactor-based ST studies since the device is simplified, compactness increased, and maintenance reduced. An experiment to show the feasibility of using a plasma centre-post (PCP) is being currently under construction and involves a high level of complexity. A preliminary study of a very simple PCP, which is ECR(Electron Cyclotron Resonance)-assisted and which includes an innovative fuelling system based on pellet injection, has recently been reported. This is highly suitable for an ultra-low aspect ratio tokamak (ULART) device. Advances on this PCP ECR-assisted concept within a ULART and the associated fuelling system are presented here, and will include the field topology for the PCP ECR-assisted scheme, pellet ablation modeling, and a possible global equilibrium simulation.

    The fast increase in obesity has been followed by the growth in the demand for plastic surgery in formerly obese patients. The weight loss is accompanied by new dysfunctions and disorders of the outline of the body that affects the quality of life of the patient. Abdominoplasty is a cosmetic surgery procedure that aims to remove the excess of skin and the redundant fat. The aim of this paper was to analyze our experience in this field and to test how functional abdominoplasty improved quality of life in the operated patients. In our Unit from January 2012 to December 2014, 25 patients (18 women and 7 men, age: 24 - 79 years, mean: 51 years) underwent abdominoplastic surgery. Only at least six months after bariatric surgery the patients were eligible for functional abdominoplasty. Average weight of the patients before surgery was 83.5 kg (range 58 - 163 Kg); averege BMI was 31 (range 24.77 - 57). The average quantity of tissue removed was 1.765 Kg (range 250 g - 11,5 Kg). Minor complications rate was in agreement with the percentages reported in literature. No mortality and major complications have occurred in our series. The majority of patients undergoing post-bariatric abdominoplasty reported an improvement in the quality of life and psychological well-being. In our opinion, however, only a multidisciplinary (surgical, psychological, dietological) approach of the post-bariatric patient allows to maintain long-term aesthetic and functional results.

    2014-01-01

    Background Cryopreservation of spermatozoa is a widely used technique to preserve the fertility of males. It can also benefit the armed forces personnel who are to be sent for long recruitments, while leaving their families behind. This study, apart from studying the effects of freezing and thawing, reveals the effect of the post thaw interval on the motility of the human spermatozoa and thus widens the insemination window period. Methods A detailed semen analysis was carried out as per the WHO guidelines for 25 samples. The samples were then washed, analysed and frozen in liquid nitrogen. The semen samples were subsequently thawed and similarly analysed after 20min and 40min of thawing. This was then followed by statistical analysis of the comparative motilities. Results Motility of sperms is found to decrease after cryopreservation. However, the study revealed that after thawing a significant increase in the motility of the sperms was noted with the progression of time (p<0.05). Conclusion By simulating conditions similar to the invivo conditions for the post thaw semen samples, we can safely wait, confirm the parameters like motility and count, and then inseminate the samples instead of blindly inseminating them immediately after thawing.

  2. Databases post-processing in Tensoral

    Dresselhaus, Eliot

    1994-01-01

    The Center for Turbulent Research (CTR) post-processing effort aims to make turbulence simulations and data more readily and usefully available to the research and industrial communities. The Tensoral language, introduced in this document and currently existing in prototype form, is the foundation of this effort. Tensoral provides a convenient and powerful protocol to connect users who wish to analyze fluids databases with the authors who generate them. In this document we introduce Tensoral and its prototype implementation in the form of a user's guide. This guide focuses on use of Tensoral for post-processing turbulence databases. The corresponding document - the Tensoral 'author's guide' - which focuses on how authors can make databases available to users via the Tensoral system - is currently unwritten. Section 1 of this user's guide defines Tensoral's basic notions: we explain the class of problems at hand and how Tensoral abstracts them. Section 2 defines Tensoral syntax for mathematical expressions. Section 3 shows how these expressions make up Tensoral statements. Section 4 shows how Tensoral statements and expressions are embedded into other computer languages (such as C or Vectoral) to make Tensoral programs. We conclude with a complete example program.

  3. Post-inflationary gravitino production revisited

    Ellis, John; Garcia, Marcos A. G.; Nanopoulos, Dimitri V.; Olive, Keith A.; Peloso, Marco

    2016-03-01

    We revisit gravitino production following inflation. As a first step, we review the standard calculation of gravitino production in the thermal plasma formed at the end of post-inflationary reheating when the inflaton has completely decayed. Next we consider gravitino production prior to the completion of reheating, assuming that the inflaton decay products thermalize instantaneously while they are still dilute. We then argue that instantaneous thermalization is in general a good approximation, and also show that the contribution of non-thermal gravitino production via the collisions of inflaton decay products prior to thermalization is relatively small. Our final estimate of the gravitino-to-entropy ratio is approximated well by a standard calculation of gravitino production in the post-inflationary thermal plasma assuming total instantaneous decay and thermalization at a time t simeq 1.2/Γphi. Finally, in light of our calculations, we consider potential implications of upper limits on the gravitino abundance for models of inflation, with particular attention to scenarios for inflaton decays in supersymmetric Starobinsky-like models.

    2015-04-01

    Aims: We report on recent optical observations of the stellar and the nebular remnants of 22 southern post-novae. Methods: In this study, for each of our targets, we obtained and analysed long-slit spectra in the spectral range 3500-6600 and in H?+[N ii] narrow-band images. Results: The changes in the emission lines' equivalent widths with the time since the outburst agree with earlier published results of other authors. We estimated an average value ? = 2.37 for the exponent of the power law fitted to the post-novae continua. Our observations clearly show the two-component structure of the V842 Cen expanding nebulae, owing to the different velocities of the ejected matter. We discovered an expanding shell around V382 Vel with an outer diameter of about 12?.

    An aircraft field study (POST; Physics of Stratocumulus Top) was conducted off the central California coast in July and August 2008 to deal with the known difficulty of measuring entrainment rates in the radiatively important stratocumulus (Sc) prevalent in that area. The Center for Interdisciplinary Remotely-Piloted Aircraft Studies Twin Otter research aircraft flew 15 quasi-Lagrangian flights in unbroken Sc and carried a full complement of probes including three high-data-rate probes: ultrafast temperature probe, particulate volume monitor probe, and gust probe. The probes' colocation near the nose of the Twin Otter permitted estimation of entrainment fluxes and rates with an in-cloud resolution of 1 m. Results include the following: Application of the conditional sampling variation of classical mixed layer theory for calculating the entrainment rate into cloud top for POST flights is shown to be inadequate for most of the Sc. Estimated rates resemble previous results after theory is modified to take into account both entrainment and evaporation at cloud top given the strong wind shear and mixing at cloud top. Entrainment rates show a tendency to decrease for large shear values, and the largest rates are for the smallest temperature jumps across the inversion. Measurements indirectly suggest that entrained parcels are primarily cooled by infrared flux divergence rather than cooling from droplet evaporation, while detrainment at cloud top causes droplet evaporation and cooling in the entrainment interface layer above cloud top.

  6. Post-analysis of learned rules

    Rule induction research implicitly assumes that after producing the rules from a dataset, these rules will be used directly by an expert system or a human user. In real-life applications, the situation may not be as simple as that, particularly, when the user of the rules is a human being. The human user almost always has some previous concepts or knowledge about the domain represented by the dataset. Naturally, he/she wishes to know how the new rules compare with his/her existing knowledge. In dynamic domains where the rules may change over time, it is important to know what the changes are. These aspects of research have largely been ignored in the past. With the increasing use of machine learning techniques in practical applications such as data mining, this issue of post analysis of rules warrants greater emphasis and attention. In this paper, we propose a technique to deal with this problem. A system has been implemented to perform the post analysis of classification rules generated by systems such as C4.5. The proposed technique is general and highly interactive. It will be particularly useful in data mining and data analysis.

  7. Psychosocial Interventions Pre and Post Bariatric Surgery.

    Despite positive results overall, a substantial number of patients experience poor long-term outcomes following bariatric surgery. One reason for variability in weight loss may be difficulty in making and sustaining changes in dietary intake and physical activity; post-surgery binge eating has also been associated with poorer weight outcomes. In this paper, we review available evidence on adjunctive psychosocial interventions for bariatric surgery patients. Although the literature is limited, evidence suggests that bariatric surgery patients may benefit from a comprehensive approach targeting diet, activity and psychological factors. We think the optimal time to initiate adjunctive intervention is after surgery, but before significant weight regain has occurred. Adaptive interventions incorporating advances in technology may prove to be effective for promoting behavioural self-management and psychosocial adjustment following bariatric surgery. For some patients, pharmacotherapy and reoperation may also play a role in a personalized approach to post-surgery care. Copyright 2015 John Wiley & Sons, Ltd and Eating Disorders Association.

    The antibacterial activity of thymol has been well established and reported in the scientific literature. Continued suppression of bacterial growth following limited exposure to antimicrobial compounds at different concentrations greater than or equal to the minimum inhibitory concentration level (MIC) and at concentrations less than the MIC can be used as an indicator of biological activity, and are respectively referred to as a post-antibacterial effect (PAE) and a post-antibiotic sub-MIC effect (PA-SME). In this study, the PAE and the PA-SME of thymol against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Bacillus cereus were investigated. A spectrophotometric method was used to determine the PAE and the PA-SME of thymol against the selected test strains. Thymol exhibited a considerable PAE and PA-SME at MIC and sub-MIC concentrations against test strains. The greatest duration of both the PAE and the PA-SME was observed for thymol against E. coli and P. aeruginosa. The PAE and PA-SME times for E. coli were 12 and 8 h, respectively, and for P. aeruginosa were 11 and 7.5 h, respectively. The duration of the PAE and PA-SME observed for S. aureus and B. cereus was shorter than for Gram-negative strains. PMID:20645735

    Post-partum bleeding was estimated during the first 72 hours in 106 women with normal delivery at term, all had live child with a body weight between 2.5 and 3.5 Kg. Three groups of women were studied: Group 1 comprised 41 volunteers with normal deliveries to whom no medication had been administered; Group 2 comprised 39 volunteers receiving 20 IU of oxytocin in 250 ml of a 5% glucose solution, immediately after delivery; and in Group 3, 26 volunteers received 0.2 mg of ergonovine maleate, orally three times daily for three days. The average post-partum blood loss in Group 1 during the first 72 hours after delivery was 151.5 +/- 12.5 ml; for Group 2, 155.9 +/- 13.9 ml; and for Group 3, 135.5 +/- 15.9 ml. There were no significant differences among the groups and, most of the blood loss occurred during the first 24 hours after delivery. PMID:3497776

    Light degrees of freedom that modify gravity on cosmological scales must be ``screened" on solar system scales in order to be compatible with data. The Vainshtein mechanism achieves this through a breakdown of classical perturbation theory, as large interactions involving new degrees of freedom become important below the so-called Vainshtein radius. We begin to develop an extension of the Parameterized Post-Newtonian (PPN) formalism that is able to handle Vainshteinian corrections. We argue that theories with a unique Vainshtein scale must be expanded using two small parameters. In this Parameterized Post-Newtonian-Vainshteinian (PPNV) expansion, the primary expansion parameter that controls the PPN order is, as usual, the velocity v. The secondary expansion parameter, ?, controls the strength of the Vainshteinian correction and is a theory-specific combination of the Schwarzschild radius and the Vainshtein radius of the source that is independent of its mass. We present the general framework and apply it to Cubic Galileon theory both inside and outside the Vainshtein radius. The PPNV framework can be used to determine the compatibility of such theories with solar system and other strong-field data.

    This report describes the selection of water compositions for the total system performance assessment (TSPA) model of results from the thermal-hydrological-chemical (THC) seepage model documented in ''Drift-Scale THC Seepage Model'' (BSC 2004 [DIRS 169856]). The selection has been conducted in accordance with ''Technical Work Plan for: Near-Field Environment and Transport: Coupled Processes (Mountain-Scale TH/THC/THM, Drift-Scale THC Seepage, and Post-Processing Analysis for THC Seepage) Report Integration'' (BSC 2004 [DIRS 171334]). This technical work plan (TWP) was prepared in accordance with AP-2.27Q, ''Planning for Science Activities''. Section 1.2.3 of the TWP describes planning information pertaining to the technical scope, content, and management of this report. The post-processing analysis for THC seepage (THC-PPA) documented in this report provides a methodology for evaluating the near-field compositions of water and gas around a typical waste emplacement drift as these relate to the chemistry of seepage, if any, into the drift. The THC-PPA inherits the conceptual basis of the THC seepage model, but is an independently developed process. The relationship between the post-processing analysis and other closely related models, together with their main functions in providing seepage chemistry information for the Total System Performance Assessment for the License Application (TSPA-LA), are illustrated in Figure 1-1. The THC-PPA provides a data selection concept and direct input to the physical and chemical environment (P&CE) report that supports the TSPA model. The purpose of the THC-PPA is further discussed in Section 1.2. The data selection methodology of the post-processing analysis (Section 6.2.1) was initially applied to results of the THC seepage model as presented in ''Drift-Scale THC Seepage Model'' (BSC 2004 [DIRS 169856]). Other outputs from the THC seepage model (DTN: LB0302DSCPTHCS.002 [DIRS 161976]) used in the P&CE (BSC 2004 [DIRS 169860], Section 6.6) were also subjected to the same initial selection. The present report serves as a full documentation of this selection and also provides additional analyses in support of the choice of waters selected for further evaluation in ''Engineered Barrier System: Physical and Chemical Environment'' (BSC 2004 [DIRS 169860], Section 6.6). The work scope for the studies presented in this report is described in the TWP (BSC 2004 [DIRS 171334]) and other documents cited above and can be used to estimate water and gas compositions near waste emplacement drifts. Results presented in this report were submitted to the Technical Data Management System (TDMS) under specific data tracking numbers (DTNs) as listed in Appendix A. The major change from previous selection of results from the THC seepage model is that the THC-PPA now considers data selection in space around the modeled waste emplacement drift, tracking the evolution of pore-water and gas-phase composition at the edge of the dryout zone around the drift. This post-processing analysis provides a scientific background for the selection of potential seepage water compositions.

  12. Atmospheric models for post- giant impact planets

    The final assembly of terrestrial planets is now universally thought to have occurred through a series of giant impacts, such as Earth's own Moon-forming impact. These collisions take place over a time interval of about 100 million years, during which time it takes at least 10 collisions between planets to make a Venus or an Earth. In the aftermath of one of these collisions the surviving planet is hot, and can remain hot for millions of years. During this phase of accretion, the proto-terrestrial planet may have a dense steam atmosphere, that will affect both the cooling of the planet and our ability to detect it. Here we explore the atmospheric chemistry, photochemistry, and spectral signatures of post-giant-impact terrestrial planets enveloped by thick atmospheres consisting of vaporized rock material. The atmospheric chemistry is computed self-consistently for atmospheres in equilibrium with hot surfaces, with compositions reflecting either the bulk silicate Earth (BSE, which includes the crust, mantle, atmosphere and oceans) or Earth's continental crust (CC). These two cases allow us to examine differences in atmospheres formed by outgassing of silica-rich (felsic) rocks - like the Earth's continental crust - and MgO- and FeO-rich (mafic) rocks - like the BSE. Studies of detrital zircons from Jack Hills, Australia, show that the continental crust existed 164 million years after the formation of the solar system, in which case the material vaporized in a giant impact should likely reflect the CC composition. However, if at the time of impact the surface of the planet does not yet exhibit the formation of continents, then the BSE case becomes relevant. We compute atmospheric profiles for surface temperatures ranging from 1000 to 2200 K, surface pressures of 10 and 100 bar, and surface gravities of 10 and 30 m/s^2. We account for all major molecular and atomic opacity sources, including collision-induced absorption, to derive the atmospheric structure and compute the reflected and emergent flux. We find that these atmospheres are dominated by H2O and CO2, while the formation of CH4, and NH3 is quenched due to short dynamical timescales. Other important constituents are HF, HCl, NaCl, and SO2. These are apparent in the emerging spectra, and can be indicative that an impact has occurred. Estimates including photochemistry and vertical mixing show that these atmospheres are enhanced in sulfur-bearing species, particularly SO2, one of the most important absorbers. At this stage we do not address cloud formation and aerosol opacity. Estimated luminosities for post-impact planets, although lower than predicted by previous models, show that the hottest post-giant-impact planets will be detectable with the planned 30 m-class telescopes. Finally, we use the models to describe the cooling of a post-impact terrestrial planet and briefly investigate its time evolution, which ends as the planet transitions into a more conventional steam atmosphere runaway greenhouse. This calculation brings a significant improvement over previous runaway greenhouse models, by including additional opacity sources and comprehensive line lists for H2O and CO2. We find that the cooling timescale for post-giant impact Earths ranges between about 10^5 and 10^6 years, where the slower cooling is associated with the planet going through a runaway greenhouse stage.

    Posterior-stabilized (PS) total knee arthroplasty (TKA) components employ a tibial post and femoral cam mechanism to guide anteroposterior knee motion in lieu of the posterior cruciate ligament. Some PS TKA patients report a clicking sensation when the post and cam engage, while severe wear and fracture of the post; we hypothesize that these complications are associated with excessive impact velocity at engagement. We evaluated the effect of implant design on engagement dynamics of the post-cam mechanism and resulting polyethylene stresses during dynamic activity. In vitro simulation of a knee bend activity was performed for four cadaveric specimens implanted with PS TKA components. Post-cam engagement velocity and flexion angle at initial contact were determined. The experimental data were used to validate computational predictions of PS mechanics using the same loading conditions. A lower limb model was subsequently utilized to compare engagement mechanics of eight TKA designs, relating differences between implants to geometric design features. Flexion angle and post-cam velocity at engagement demonstrated considerable ranges among designs (23-89, and 0.05-0.22 mm/, respectively). Post-cam velocity was correlated (r = 0.89) with tibiofemoral condylar design features. Condylar geometry, in addition to post-cam geometry, played a significant role in minimizing engagement velocity and forces and stresses in the post. This analysis guides selection and design of PS implants that facilitate smooth post-cam engagement and reduce edge loading of the post. PMID:23606458

  15. Achieving enhanced and tunable adhesion via composite posts

    Surfaces with enhanced and tunable adhesion have a variety of applications, including microtransfer printing of semiconductor elements, material handling in manufacturing, and gripping surfaces on climbing robots. Traditionally, schemes to achieve tunable adhesion have relied on fabricating arrays of posts or fibers with complex geometries, such as angled posts terminated by wider caps. Here, we describe an alternative to post structures with complex geometries through the use of composite posts that consist of a stiff core and a compliant shell. Posts consisting of a stiff core and compliant shell have enhanced adhesion under normal loading, and the pull-off can be reduced via the application of shear. The adhesion mechanics of composite posts are demonstrated here through a combination of finite element simulations and experimental measurements on individual millimeter-scale posts.

    Teeth that have short clinical crown, which are not alone enough to support the definitive restoration can be best treated using the post and core system. The advantages of fiber post over conventional metallic post materials have led to its wide acceptance. In addition to that the combination of aesthetic and mechanical benefits of fiber post has provided it with a rise in the field of dentistry. Also the results obtained from some clinical trials have encouraged the clinicians to use the fiber posts confidently. Fiber posts are manufactured from pre-stretched fibers impregnated within a resin matrix. The fibers could that be of carbon, glass/silica, and quartz, whereas Epoxy and bis-GMA are the most widely used resin bases. But recently studies are also found to be going on for polyimide as possible material for the fiber post resin base as a substitute for the conventional materials. PMID:24605208

    One of the clinically relevant problems dentists face when restoring endodontically treated teeth is the mismatch between fiber post and post space diameters, which results in an excessively thick resin cement layer. Fiber post relining appears as a solution for this problem. Objectives: The aim of this study was to evaluate the effect of fiber post relining with composite resin on push-out bond strength. Material and Methods: Twenty bovine incisors were selected to assess post retention. The crowns were removed below the cementoenamel junction and the root canals were treated endodontically and flared with diamond burs. The roots were allocated into two groups (n=10): G1: fiber posts without relining and G2: fiber posts relined with composite resin. The posts were cemented with a dual-cured resin cement and the specimens were sectioned transversally. Three 1.5-mm thick slabs were obtained per root and identified as cervical, medium and apical thirds. The push-out test was performed at a crosshead speed of 0.5 mm/min until post dislodgement occurred. The failure mode of fractured specimens was analyzed under scanning electron microscopy. Data were analyzed by split-plot ANOVA and post-hoc Tukey's test at a pre-set alpha of 0.05. Results: Relined fiber posts presented higher retention values than non-relined post in all thirds. No statistically significant differences (p>0.05) were found among thirds for relined posts. All failures occurred at the interface between resin cement and root dentin. Conclusions: Relining with composite resin seems to be an effective method to improve the retention of fiber posts to flared root canals. PMID:20027434

    The Mars Science Laboratory (MSL) Curiosity rover landed safely on Mars August 5th, 2012 at 10:32 PDT, Earth Received Time. Immediately following touchdown confirmation, best estimates of position were calculated to assist in determining official MSL locations during entry, descent and landing (EDL). Additionally, estimated balance mass impact locations were provided and used to assess how predicted locations compared to actual locations. For MSL, the Program to Optimize Simulated Trajectories II (POST2) was the primary trajectory simulation tool used to predict and assess EDL performance from cruise stage separation through rover touchdown and descent stage impact. This POST2 simulation was used during MSL operations for EDL trajectory analyses in support of maneuver decisions and imaging MSL during EDL. This paper presents the simulation methodology used and results of pre/post-landing MSL location estimates and associated imagery from Mars Reconnaissance Orbiter s (MRO) High Resolution Imaging Science Experiment (HiRISE) camera. To generate these estimates, the MSL POST2 simulation nominal and Monte Carlo data, flight telemetry from onboard navigation, relay orbiter positions from MRO and Mars Odyssey and HiRISE generated digital elevation models (DEM) were utilized. A comparison of predicted rover and balance mass location estimations against actual locations are also presented.

The apparatus consists of a fast retropulse or post pulse shutter to suppress target reflection and/or beam return. This is accomplished by either quickly placing a solid across the light transmitting aperture of a component in the chain, such as a spatial filter pinhole, or generating and directing a plasma with sufficiently high density across the aperture, so as to, in effect, close the aperture to the returning amplified energy pulse. 13 figs.

    The Post Street project had four (4), 7.960 MW, Solar Taurus-70-10801S natural gas combustion turbines. Each turbine equipped with a 40,000 lb/hr heat recovery steam generator (HRSG). The dual-fuel HRSGs was capable of generating steam using gas turbine exhaust heat or surplus electric power. The generation capacity was nominally rated at 29.2 MW. The project as proposed had a fuel rate chargeable to power of 4,900 - 5,880 Btu/kWh dependent on time of year. The CHP plant, when operating at 29.2 MW, can recycle turbine exhaust into supply 145 kpph of steam to SSC per hour. The actual SSC steam loads will vary based on weather, building occupation, plus additions / reductions of customer load served. SSC produces up to 80 kpph of steam from a biomass boiler, which is currently base loaded all year.

    Post Irradiation Effects (PIE) ranging from normal recovery to catastrophic failure have been observed in integrated circuits during the PIE period. Data presented show failure due to rebound after a 10 krad(Si) dose. In particular, five device types are investigated with varying PIE response. Special attention has been given to the HI1-507A analog multiplexer because its PIE response is extreme. X-ray diffraction has been uniquely employed to measure physical stress in the HI1-507A metallization. An attempt has been made to show a relationship between stress relaxation and radiation effects. All data presented in this paper support the current Method 1019.4 but demonstrate the importance of performing PIE measurements, even when mission doses are as low as 10 krad(Si).

    Post-Exertional Malaise (PEM) is a cardinal symptom of the illnesses referred to as Myalgic Encephalomyelitis (ME), Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS), and chronic fatigue syndrome (CFS). PEM is reported to occur in many of these patients, and with several criteria (e.g., ME and ME/CFS), this symptom is mandatory (Carruthers et al., 2003, 2011). In the present study, 32 participants diagnosed with CFS (Fukuda et al., 1994) were examined on their responses to self-report items that were developed to capture the characteristics and patterns of PEM. As shown in the results, the slight differences in wording for various items may affect whether one is determined to have PEM according to currently used self-report criteria to assess CFS. Better understanding of how this symptom is assessed might help improve the diagnostic reliability and validity of ME, ME/CFS, and CFS. PMID:25584525

    Post-operative capsular opacification is a multifactorial physiological consequence of cataract surgery. Opacification involving the central posterior capsule has a significant impact on high and low contrast acuity and low contrast sensitivity. The assessment of Posterior Capsule Opacification (PCO) on cadaver eyes, experimental studies, culture models and in clinical studies has provided an understanding of its pathogenesis. The proliferation, migration and abnormal differentiation of residual lens epithelial cells and fibers in the capsular bag have been implicated in the pathogenesis of PCO. The incidence and severity of PCO correlates to the meticulous use of surgical techniques, IOL optic edge designs and IOL materials. This article summarizes the clinical studies with recommendations for retarding the development of central PCO. It discusses experiments with pharmacological agents broadly categorized as anti-inflammatory, immuno-modulating, antiproliferative, antiadhering, antitransdifferentiating agents for the prevention of PCO. These studies will remain critical for future endeavors undertaken for eradication of PCO. PMID:23675049

    The timing method enables to search planets in extreme conditions, e.g. as companion to pulsars or as planets in post-common envelope binaries (PCEB). In both cases, the planetary systems have experience a dramatic evolution of the primary star.Eclipse time variations in PCEBs with white dwarfs and subdwarf-B stars as primaries have been interpreted as signatures from circumbinary planets and planetary systems. Several of these interpretations have been questioned later on, either due to dynamical instability of the proposed planetary systems or due to non-detection of the proposed companions. We will give an overview of our long-term monitoring of PCEB systems and the modelling in terms of Keplerian and Newtonian planetary orbits in order to assess the circumbinary planet scenario for these systems. We discuss the implications for the first-generation or second-generatoin planet scenario for these potential planets around these evolved stars.

    Biliary tract complications remain a common source of morbidity and mortality in liver transplant (LT) recipients with an estimated incidence of 530% after orthotopic LT and a mortality rate of up to 10%. Biliary complications after LT may be related to various factors including hepatic artery thrombosis or stenosis, ischemia reperfusion injury, immunologic injury, infections, donor pool, and technical issues which include imperfect anastomosis and T-tube-related complications. Management of the detected biliary complications includes nonsurgical and surgical methods. A majority of these post transplant biliary complications can be treated with endoscopic retrograde cholangiography. If unsuccessful, a percutaneous intervention or surgery may be required. In this article, we review the incidence, clinical presentation, and management of the main types of biliary complications. PMID:25755409

    Post-irradiation effects (PIE) ranging from normal recovery to catastrophic failure have been observed in integrated circuits during the PIE period. Data presented show failure due to rebound after a 10 krad(Si) dose. In particular, five device types are investigated with varying PIE response. Special attention has been given to the HI1-507A analog multiplexer because its PIE response is extreme. X-ray diffraction has been uniquely employed to measure physical stress in the HI1-507A metallization. An attempt has been made to show a relationship between stress relaxation and radiation effects. All data presented support the current MIL-STD Method 1019.4 but demonstrate the importance of performing PIE measurements, even when mission doses are as low as 10 krad(Si).

  10. Aspergillus Pseudoaneurysm Post Aortic Valve Replacement

    2014-01-01

    Thoracic aortic mycotic aneurysms caused by Aspergillus fumigatus postoperatively are rare and devastating complications. These cases are usually attributed to intraoperative contamination of surgical equipment. We present a patient who had an ascending aortic mycotic aneurysm 20 weeks post aortic valve replacement. A high index of suspicion allowed for diagnosis and prompt treatment, although the patient presented in an unusual manner. Treatment included both medical and surgical therapy to minimize morbidity and mortality. Despite treatment our patient suffered long-lasting consequences due to the aggressive nature of the disease. Cases presented in the literature and this experience show that a high index of suspicion must be maintained in such patients regardless of immune status and postoperative interval, in order to avoid long-lasting sequelae.

  11. Cell detachment: post-isolation challenges.

    PubMed

    Zheng, Qin; Iqbal, Samir M; Wan, Yuan

    2013-12-01

    Rare cells already have become established indicators for disease diagnosis, to help track prognosis, and in developing personalized therapy. Numerous techniques have been developed to effectively and specifically detect and sort rare cells and cell isolation techniques have gained much attention among researchers in the last few decades. Recent developments in nanotechnologies and microfluidics have been used with great promise towards these goals. The research emphasis has also shifted from simple detection with microfluidic devices to comprehensive isolation, collection and subsequent analysis with integrated and automated systems. The first challenge in post-isolation analysis is cell detachment from substrates, while keeping cells viable and unperturbed. In this review, various methods used for cell detachments are discussed. For effective cell sorting, the detachment is identified as critical criteria for selecting substrates and methods. PMID:23978676

  12. Hair Transplantation: Preventing Post-operative Oedema.

    Swelling or oedema of forehead or eyelids is a common consequence of hair transplantation surgery. However, this results in increased morbidity and absence from work due to unaesthetic appearance. To study various physical and therapeutic modalities to reduce or completely prevent the occurrence of such oedema. Three hundred forty hair transplant patients were recruited in the study and were categorized into 8 groups depending upon the intervention employed. There were 32 dropouts in the study due to various reasons. Patients who were administered steroid with tumescent solution had the highest number of patients without oedema, with only 3 out of 117 patients developing oedema. Physical measures like position of head during sleeping, application of occlusion bands or ice packs did not show satisfactory results. Addition of triamcinolone to tumescent anaesthetic solution is a very effective technique of preventing post-operative swelling. PMID:21031066

  13. Mechanisms of post-flight orthostatic intolerance

    1994-01-01

    Post-flight orthostatic intolerance is a dramatic physiological consequence of human adaptation to microgravity made inappropriate by a sudden return to 1-G. The immediate mechanism is almost always a failure to maintain adequate tissue perfusion, specifically perfusion of the central nervous system, but vestibular dysfunction may occasionally be the primary cause. Orthostatic intolerance is present in a wide range of clinical disorders of the nervous and cardiovascular systems. The intolerance that is produced by spaceflight and 1-G analogs (bed rest, head-down tilt at a moderate angle, water immersion) is different from its clinical counterparts by being only transiently present in subjects who otherwise have normal cardiovascular and regulatory systems. However, the same set of basic pathophysiological elements should be considered in the analysis of any form of orthostatic intolerance.

  14. Thermal instability in post-flare plasmas

    Antiochos, S. K.

    1976-01-01

    The cooling of post-flare plasmas is discussed and the formation of loop prominences is explained as due to a thermal instability. A one-dimensional model was developed for active loop prominences. Only the motion and heat fluxes parallel to the existing magnetic fields are considered. The relevant size scales and time scales are such that single-fluid MHD equations are valid. The effects of gravity, the geometry of the field and conduction losses to the chromosphere are included. A computer code was constructed to solve the model equations. Basically, the system is treated as an initial value problem (with certain boundary conditions at the chromosphere-corona transition region), and a two-step time differencing scheme is used.

  15. Post Eruption Hazards at Mt. Pinatubo, Philippines

    2004-01-01

    Our project focused on the investigation of the post-eruption hazards at Mt. Pinatubo (Philippines) using remote sensing data, and field observations of the 1991 eruption deposits. Through the use of multiple satellite images, field work, and the 1996/2000 PacRim data sets, we conducted studies of the co- and post-eruption hazards of the volcano due to erosion and re-deposition of the extensive pyroclastic flow deposits. A major part of this project was the assembly and analysis of a database of over 50 high resolution (1 - 50 m/pixel) images that will facilitate this study. We collected Ikonos, SPOT, SIR-C/X-SAR, Landsat, ERS, RADARSAT, and ASTER images of the area around Mt. Pinatubo. An example of the changes that could be seen in these data is shown. Our investigation focused on a retrospective analysis of the erosion, redeposition, and re-vegetation of the 1991 pyroclastic flow deposits of Mt. Pinatubo. The primary geologic goal of our work was the analysis of the spatial distribution and volume change of the sources and sinks of materials associated with mudflow ('lahar') events. This included the measurement of river valley gradients and cross-sections using TOPSAR digital elevation data, as we are participating in the PacRim 2000 deployment to the Philippines specifically so that we can collect a second set of TOPSAR data that can then be used to create a topographic difference image of the volcano. The main results from this multi-sensor study have been published as Torres et al.. A discussion of the methodology that we used to assemble an appropriate database was included in Mouginis-Mark and Domergue-Schmidt. As part of an educational outreach effort, we also helped the Philippine Institute of Volcanology and Seismology (PHIVOLCS) in the Philippines to use NASA data to study Mt. Pinatubo and other Filipino volcanoes.

  16. Post-thrombotic syndrome: a clinical review.

    Up to half of patients with proximal deep vein thrombosis (DVT) will develop post-thrombotic syndrome (PTS) despite optimal anticoagulant therapy. PTS significantly impacts upon quality of life and has major health-economic implications. This narrative review describes the pathophysiology, risk factors, and diagnosis, prevention and treatment of PTS, to improve our understanding of the disease and guide treatment. Relevant articles were identified through systematic searches of the PubMed, EMBASE and Cochrane databases between 1966 and November 2011. Studies were included for detailed assessment if they met the following criteria: published in English, human study participants, study population aged >18years, and lower limb post-thrombotic syndrome. All non-systematic reviews and single patient case reports were excluded. Recurrent thrombosis, thrombus location and obesity are major risk factors, whereas the importance of gender and age remain uncertain. The diagnosis of PTS is based on clinical findings in patients with a known history of DVT. Several clinical scales have been described, with the Villalta Score gaining increasing popularity. Adequate anticoagulation and use of elastic compression stockings (ECS) following DVT can reduce the incidence of PTS. Catheter-directed thrombolysis and mechanical thrombectomy of acute DVT may preserve valvular function. Studies to date of these techniques are encouraging, and have reported improved hemodynamics and a reduced incidence of PTS. The management of established PTS is challenging. Compression therapy, aimed at reducing the underling venous hypertension, remains the mainstay of treatment. This is despite a paucity of high-quality evidence to support its use. Pharmacologic and surgical treatments have also been described, with a number of studies citing symptomatic improvement. PMID:23433231

    2015-01-01

    Problem Typhoon Haiyan damaged or destroyed health infrastructure, equipment and services essential to the Philippine National Tuberculosis Programme (NTP), and it had to be re-established in the affected areas in Regions 6, 7 and 8. Continuing treatment and restoring diagnostic capacity were also challenging. Context The Philippines has one of the highest tuberculosis (TB) burdens in the world. At the time of Typhoon Haiyan, there were an estimated 26600 TB cases on treatment at directly observed treatment, short-course (DOTS) centres and 356 multidrug-resistant TB cases registered at programmatic management of drug-resistant TB (PMDT) sites. As TB was not included in the Philippines early-warning post-disaster surveillance system, tracking TB patients was difficult after Haiyan. Actions and outcomes Immediately following Haiyan, each aspect of the NTP was assessed to determine the extent of damage. TB patients were traced and services restored. We created maps showing the location of temporary TB diagnostic and treatment services, which hastened referrals. We provided new laboratory equipment, training and rapid testing capabilities in the affected regions. All TB services in the affected areas (473 DOTS, 490 TB microscopy and six PMDT facilities) were restored just two months after Haiyan. Lessons learnt Key lessons learnt from the NTP experience following Tyhoon Haiyan were: (1) the importance of having an electronic TB registry (database); (2) the need to include TB in the post-disaster surveillance system; (3) clear guidelines for TB control in disasters; and (4) the importance of coordination with all partners.

  18. POST Earthquake Debris Management - AN Overview

    NASA Astrophysics Data System (ADS)

    Sarkar, Raju

    Every year natural disasters, such as fires, floods, earthquakes, hurricanes, landslides, tsunami, and tornadoes, challenge various communities of the world. Earthquakes strike with varying degrees of severity and pose both short- and long-term challenges to public service providers. Earthquakes generate shock waves and displace the ground along fault lines. These seismic forces can bring down buildings and bridges in a localized area and damage buildings and other structures in a far wider area. Secondary damage from fires, explosions, and localized flooding from broken water pipes can increase the amount of debris. Earthquake debris includes building materials, personal property, and sediment from landslides. The management of this debris, as well as the waste generated during the reconstruction works, can place significant challenges on the national and local capacities. Debris removal is a major component of every post earthquake recovery operation. Much of the debris generated from earthquake is not hazardous. Soil, building material, and green waste, such as trees and shrubs, make up most of the volume of earthquake debris. These wastes not only create significant health problems and a very unpleasant living environment if not disposed of safely and appropriately, but also can subsequently impose economical burdens on the reconstruction phase. In practice, most of the debris may be either disposed of at landfill sites, reused as materials for construction or recycled into useful commodities Therefore, the debris clearance operation should focus on the geotechnical engineering approach as an important post earthquake issue to control the quality of the incoming flow of potential soil materials. In this paper, the importance of an emergency management perspective in this geotechnical approach that takes into account the different criteria related to the operation execution is proposed by highlighting the key issues concerning the handling of the construction and demolition debris following an earthquake.

  19. Randomness in post-selected events

    Bell inequality violations can be used to certify private randomness for use in cryptographic applications. In photonic Bell experiments, a large amount of the data that is generated comes from no-detection events and presumably contains little randomness. This raises the question as to whether randomness can be extracted only from the smaller post-selected subset corresponding to proper detection events, instead of from the entire set of data. This could in principle be feasible without opening an analogue of the detection loophole as long as the min-entropy of the post-selected data is evaluated by taking all the information into account, including no-detection events. The possibility of extracting randomness from a short string has a practical advantage, because it reduces the computational time of the extraction. Here, we investigate the above idea in a simple scenario, where the devices and the adversary behave according to i.i.d. strategies. We show that indeed almost all the randomness is present in the pair of outcomes for which at least one detection happened. We further show that in some cases applying a pre-processing on the data can capture features that an analysis based on global frequencies only misses, thus resulting in the certification of more randomness. We then briefly consider non-i.i.d strategies and provide an explicit example of such a strategy that is more powerful than any i.i.d. one even in the asymptotic limit of infinitely many measurement rounds, something that was not reported before in the context of Bell inequalities.

    Post-stroke depression is an important psychological consequence of ischemic stroke, and affects around one third of stroke patients at any time post-stroke. It has a negative impact on patient morbidity and mortality, and as such development of effective post-stroke recognition and treatment strategies are very important. There are several therapeutic strategies for post-stroke depression, including both pharmacological and non-pharmacological approaches. In this review, we present evidence regarding the underlying biology of post-stroke depression, commonalities between post-stroke depression and Major Depressive Disorder and explore several treatment approaches, including antidepressant therapy, psychotherapy, surgical therapy, electroconvulsive therapy, acupuncture, music therapy and natural products. Further experimental and clinical studies are required, particularly in emerging fields such as the role of nutraceuticals in the treatment of stroke. PMID:24852795

  1. Post-primary science teachers' perceptions of primary science education

    1993-12-01

    Post-primary science teachers in Victoria were asked to express views about primary science curriculum design and implementation. They were also asked about the value of continuity between primary and post-primary science education. The post-primary teachers generally had favourable attitudes to primary science education and considered that cooperation would be useful-though it is not common at the moment. However, the data revealed a considerable range of opinion. Post-primary science teachers' views about primary science curriculum are similar to those of primary teachers themselves, but many post-primary teachers would place more emphasis on formal or textbook knowledge. Post-primary teachers see a number of systemic problems in implementing primary science education but their positive perceptions suggest the value of encouraging more structured links. The notion of continuity across the two sectors was well supported.

  2. Post-Traumatic Stress Symptoms in Post-ICU Family Members: Review and Methodological Challenges.

    2016-01-01

    Family members of intensive care unit (ICU) patients are at risk for symptoms of post-traumatic stress disorder (PTSD) following ICU discharge. The aim of this systematic review is to examine the current literature regarding post-ICU family PTSD symptoms with an emphasis on methodological issues in conducting research on this challenging phenomenon. An extensive review of the literature was performed confining the search to English language studies reporting PTSD symptoms in adult family members of adult ICU patients. Ten studies were identified for review published from 2004 to 2012. Findings demonstrate a significant prevalence of family PTSD symptoms in the months following ICU hospitalization. However, there are several methodological challenges to the interpretation of existing studies and to the conduct of future research including differences in sampling, identification of risk factors and covariates of PTSD, and lack of consensus regarding the most appropriate PTSD symptom measurement tools and timing.

    Post-fledging activities of 18 Ferruginous Hawks (Buteo regalis) were studied in southcentral North Dakota during July and August 1979. The post-fledging period ranged from 10 to 40 d (mean = 23.1 d; N = 16). Haylands and native prairie grasslands were the principal land use types utilized by fledglings and adults. Mortality of young during post-fledging was 11% (N = 2).

  14. Recent Shuttle Post Flight MMOD Inspection Highlights

    NASA Technical Reports Server (NTRS)

    Hyed, James L.; Christiansen, Eric L.; Lear, Dana M.; Herrin, Jason S.

    2009-01-01

    Post flight inspections on the Space Shuttle Atlantis conducted after the STS-11.5 mission revealed a 0.11 inch (2.8 mm) hole in the outer face sheet of the starboard payload bay door radiator panel #4. The payload bay door radiators in this region are 0.5 inch (12.7 mm) thick aluminum honeycomb with 0.011 in (0.279 mm) thick aluminum face sheets topped with 0.005 in (0.127 mm) silver-Teflon tape. Inner face sheet damage included a 0.267 in (6.78 mm) long through crack with measureable deformation in the area of 0.2 in (5.1 mm). There was also a 0.031 in (0.787 nun) diameter hole in the rear face sheet. A large approximately l in (25 mm) diameter region of honeycomb was also destroyed. Since the radiators are located on the inside of the shuttle payload bay doors which are closed during ascent and reentry, the damage could only have occurred during the on-orbit portion of the mission. During the August 2007 STS-118 mission to the International Space Station, a micro-meteoroid or orbital debris (MMOD) particle impacted and completely penetrated one of shuttle Endeavour's radiator panels and the underlying thermal control system (TCS) blanket, leaving deposits on (but no damage to) the payload bay door. While it is not unusual for shuttle orbiters to be impacted by small MMOD particles, the damage from this impact is larger than any previously seen on the shuttle radiator panels. One of the largest impacts ever observed on a crew module window occurred during the November 2008 STS-126 mission to the International Space Station. Damage to the window was documented by the crew on orbit. Post flight inspection revealed a 0.4 in (10.8 mm) crater in the window pane, with a depth of 0.03 in (0.76 mm). The window pane was replaced due to the damage caused by this impact. Analysis performed on residue contained in dental mold impressions taken of the site indicated that a meteoroid particle produced this large damage site. The post flight inspection after the subsequent mission, STS-119 in March of 2009, produced a large MMOD impact feature in a wing leading edge reinforced carbon-carbon panel. The crater measured 0.18 in (4.5 nun) in diameter and was nearly 0.037 in (0.93 nun) deep. The thickness of the silicon carbide coating that protects the carbon substrate is nominally 0.02 in (0.5 nun) to 0.04 in (1 mm), making this a significant impact into the RCC. The damage occurred on the upper surface of the panel, which experiences lower heat loads on re-entry. This poster will document the data collected from the impact sites and will include results of the Scanning Electron Microscope/Energy Dispersive X-ray (SEM/EDX) analysis. Evidence will be presented that suggests a source of the impacts.

    Involuntary abnormal movements have been reported after ischaemic and haemorrhagic stroke. Post stroke movement disorders can appear as acute or delayed sequel. At the moment, for many of these disorders the knowledge of pharmacological treatment is still inadequate. Dopaminergic and GABAergic systems may be mainly involved in post-stroke movement disorders. This article provides a review on drugs commonly used in post-stroke movement disorders, given that some post-stroke movement disorders have shown a partial benefit with pharmacological approach.

    2002-01-01

    The aim of this study was to investigate the post-cyclic transmission of Acanthocephalus tumescens (von Linstow, 1896) from Galaxias maculatus Jenyns to Oncorhynchus mykiss (Walbaum). Wild G. maculatus naturally infected with A. tumescens were fed to cultured rainbow trout, which were sacrificed at the second, third and fourth weeks post infection. Normally attached male and female acanthocephalans were recovered alive from the intestine of rainbow trout. Parasites survive at least four weeks post infection, growing and attaining full sexual maturity. Prevalence and mean intensity generally decreased after infection. A. tumescens is the eighth acanthocephalan species in which post-cyclic transmission has been proven. PMID:12194485

    Multidisciplinary analysis often requires optimization of nonlinear systems that are subject to constraints. Trajectory optimization is one example of this situation. The Program to Optimize Simulated Trajectories (POST) was used successfully for a number of problems. The purpose is to describe POST and a new optimization approach that has been incorporated into it. Typical uses of POST will also be illustrated. The projected-gradient approach to optimization is the preferred option in POST and is discussed. A new approach to optimization, the random-walk approach, is described, and results with the random-walk approach are presented.

    The occurrence of the secondary disasters of forest fire has significant impacts on the environment quality and human health and safety. Post-fire debris flow is one of the most hazardous secondary disasters of forest fire. To understand the occurrence conditions of post-fire debris flow and to master its occurrence situation are the critical elements in post-fire hazard assessment. From the viewpoints of vegetation, precipitation threshold and debris flow material sources, this paper elaborated the impacts of forest fire on the debris flow, analyzed the geologic and geomorphic conditions, precipitation and slope condition that caused the post-fire debris flow as well as the primary mechanisms of debris-flow initiation caused by shallow landslide or surface runoff, and reviewed the research progress in the prediction and forecast of post-fire debris flow and the related control measures. In the future research, four aspects to be focused on were proposed, i. e., the quantification of the relationships between the fire behaviors and environmental factors and the post-fire debris flow, the quantitative research on the post-fire debris flow initiation and movement processes, the mechanistic model of post-fire debris flow, and the rapid and efficient control countermeasures of post-fire debris flow.

  8. Recovery post treatment: plans, barriers and motivators

    PubMed Central

    2013-01-01

    Background The increasing focus on achieving a sustained recovery from substance use brings with it a need to better understand the factors (recovery capital) that contribute to recovery following treatment. This work examined the factors those in recovery perceive to be barriers to (lack of capital) or facilitators of (presence of capital) sustained recovery post treatment. Methods A purposive sample of 45 participants was recruited from 11 drug treatment services in northern England. Semi-structured qualitative interviews lasting between 30 and 90 minutes were conducted one to three months after participants completed treatment. Interviews examined key themes identified through previous literature but focused on allowing participants to explore their unique recovery journey. Interviews were transcribed and analysed thematically using a combination of deductive and inductive approaches. Results Participants generally reported high levels of confidence in maintaining their recovery with most planning to remain abstinent. There were indications of high levels of recovery capital. Aftercare engagement was high, often through self referral, with non substance use related activity felt to be particularly positive. Supported housing was critical and concerns were raised about the ability to afford to live independently with financial stability and welfare availability a key concern in general. Employment, often in the substance use treatment field, was a desire. However, it was a long term goal, with substantial risks associated with pursuing this too early. Positive social support was almost exclusively from within the recovery community although the re-building of relationships with family (children in particular) was a key motivator post treatment. Conclusions Addressing internal factors and underlying issues i.e. ‘human capital’, provided confidence for continued recovery whilst motivators focused on external factors such as family and maintaining aspects of a ‘normal’ life i.e. ‘social and physical capital’. Competing recovery goals and activities can leave people feeling under pressure and at risk of taking on or being pushed to do too much too soon. The breadth of re-integration and future plans at this stage is limited primarily to the recovery community and treatment sector. Services and commissioners should ensure that this does not become a limiting factor in individuals’ long term recovery journeys. PMID:23363550

    Thousands of persons have survived Ebola virus disease. Almost all survivors describe symptoms that persist or develop after hospital discharge. A cross-sectional survey of the symptoms of all survivors from the Ebola treatment unit (ETU) at 34th Regimental Military Hospital, Freetown, Sierra Leone (MH34), was conducted after discharge at their initial follow-up appointment within 3 weeks after their second negative PCR result. From its opening on December 1, 2014, through March 31, 2015, the MH34 ETU treated 84 persons (8–70 years of age) with PCR-confirmed Ebola virus disease, of whom 44 survived. Survivors reported musculoskeletal pain (70%), headache (48%), and ocular problems (14%). Those who reported headache had had lower admission cycle threshold Ebola PCR than did those who did not (p<0.03). This complete survivor cohort from 1 ETU enables analysis of the proportion of symptoms of post-Ebola syndrome. The Ebola epidemic is waning, but the effects of the disease will remain.

    Five patients: three children, one adolescent, and one young adult, examined in an emergency room setting were diagnosed with post-traumatic transient cortical blindness. This syndrome is characterized by transient visual loss, normal pupillary response and normal funduscopic examination following minor head trauma. In each case, vision returned to normal within minutes to hours following injury, leaving no neurological sequelae. Headache, confusion, irritability, anxiety, nausea and vomiting were the most common related symptoms. While the mechanism responsible for the transient blindness is unknown, most authors propose an abnormal vascular response to trauma with resultant transient hypoxia and cerebral dysfunction. The similarity between the symptoms accompanying this syndrome and those seen during a classic migraine attack has led many investigators to suggest a common underlying pathophysiology. The purpose of this report is to highlight the salient clinical features and diagnostic approaches to this syndrome, thereby providing ophthalmologists and emergency room physicians a heightened awareness of this entity and the means to detect it.

    The Next Generation Nuclear Plant (NGNP) Graphite R&D program is currently measuring irradiated material property changes in several grades of nuclear graphite for predicting their behavior and operating performance within the core of new Very High Temperature Reactor (VHTR) designs. The Advanced Graphite Creep (AGC) experiment consisting of six irradiation capsules will generate this irradiated graphite performance data for NGNP reactor operating conditions. All six AGC capsules in the experiment will be irradiated in the Advanced Test Reactor (ATR), disassembled in the Hot Fuel Examination Facility (HFEF), and examined at the INL Research Center (IRC) or Oak Ridge National Laboratory (ORNL). This is the first in a series of status reports on the progress of the AGC experiment. As the first capsule, AGC1 was irradiated from September 2009 to January 2011 to a maximum dose level of 6-7 dpa. The capsule was removed from ATR and transferred to the HFEF in April 2011 where the capsule was disassembled and test specimens extracted from the capsules. The first irradiated samples from AGC1 were shipped to the IRC in July 2011and initial post irradiation examination (PIE) activities were begun on the first 37 samples received. PIE activities continue for the remainder of the AGC1 specimen as they are received at the IRC.

    Individuals with chronic stroke have reduced perfusion of the paretic lower limb at rest; however, the hyperemic response to graded muscle contractions in this patient population has not been examined. This study quantified blood flow to the paretic and non-paretic lower limbs of subjects with chronic stroke after submaximal contractions of the knee extensor muscles and correlated those measures with limb function and activity. Ten subjects with chronic stroke and ten controls had blood flow through the superficial femoral artery quantified with ultrasonography before and immediately after 10 second contractions of the knee extensor muscles at 20, 40, 60, and 80% of the maximal voluntary contraction (MVC) of the test limb. Blood flow to the paretic and non-paretic limb of stroke subjects was significantly reduced at all load levels compared to control subjects even after normalization to lean muscle mass. Of variables measured, increased blood flow after an 80% MVC was the single best predictor of paretic limb strength, the symmetry of strength between the paretic and non-paretic limbs, coordination of the paretic limb, and physical activity. The impaired hemodynamic response to high intensity contractions was a better predictor of lower limb function than resting perfusion measures. Stroke-dependent weakness and atrophy of the paretic limb do not explain the reduced hyperemic response to muscle contraction alone as the response is similarly reduced in the non-paretic limb when compared to controls. These data may suggest a role for perfusion therapies to optimize rehabilitation post stroke. PMID:26630380

    The natural course of post-traumatic peritonitis was studied in 17 pigs. Following a standardized missile wound to the abdomen the pigs were operated on and observed in continuous anesthesia for periods up to 3 days. Bacterial density was measured in peritoneal exudate, parietal peritoneum, laparotomy wound, and projectile entrance and exit wounds at this operation and also at relaparotomy, which terminated the experiments. The bacterial density showed significant perioperative fall, averaging X 1,905 in peritoneal exudate and X 40 in parietal peritoneum. From a low postoperative level (mean c. 10(2)/ml or /gm), bacterial density increased significantly in the observation period. In peritoneal exudate the increase was X 4,073 and in peritoneum X 2,630. In laparotomy and projectile entrance and exit wounds the corresponding figures were X 234, X 126, and X 15. The bacterial population's perioperative reduction and subsequent proliferation were interpreted as reflecting the host defense, which accordingly was limited in capacity and duration. PMID:4020915

    Post-herpetic neuralgia (PHN) is a chronic neuropathic pain condition that persists 3 months or more following an outbreak of shingles. Shingles, also known as acute herpes zoster, is associated with the reactivation of the dormant varicella zoster virus in an individual who has experienced chicken pox. PHN is associated with persistent and often refractory neuropathic pain. Patients may experience multiple types of pain including a constant deep, aching, or burning pain; a paroxysmal, lancinating pain; hyperalgesia (painful stimuli are more painful than expected); and allodynia (pain associated with typically non-painful stimuli). The pharmacological treatment of PHN may include a variety of medications including alpha-2 delta ligands (gabapentin and pregabalin), other anticonvulsants (carbamazepine), tricyclic antidepressants (amitriptyline, nortriptyline, doxepin), topical analgesics (5 % lidocaine patch, capsaicin) tramadol, or other opioids. The considerable side effect profiles of the commonly used oral medications often limit their practical use, and a combination of both topical and systemic agents may be required for optimal outcomes. Physicians and other treatment providers must tailor treatment based on the response of individual patients. PMID:26879875

    Half of all long-term (> 10 year) australian kidney transplant recipients (KTR) will develop squamous cell carcinoma (SCC) or solid organ cancer (SOC), making cancer the leading cause of death with a functioning graft. At least 30% of KTR with a history of SCC or SOC will develop a subsequent SCC or SOC lesion. Pharmacological immunosuppression is a major contributor of the increased risk of cancer for KTR, with the cancer lesions themselves further adding to systemic immunosuppression and could explain, in part, these phenomena. Immune profiling includes; measuring immunosuppressive drug levels and pharmacokinetics, enumerating leucocytes and leucocyte subsets as well as testing leucocyte function in either an antigen specific or non-specific manner. Outputs can vary from assay to assay according to methods used. In this review we define the rationale behind post-transplant immune monitoring assays and focus on assays that associate and/or have the ability to predict cancer and rejection in the KTR. We find that immune monitoring can identify those KTR of developing multiple SCC lesions and provide evidence they may benefit from pharmacological immunosuppressive drug dose reductions. In these KTR risk of rejection needs to be assessed to determine if reduction of immunosuppression will not harm the graft. PMID:25664246

    Vascular compromise and the accompanying perfusion deficits cause or complicate a large array of disease conditions and treatment failures. This has prompted the exploration of therapeutic strategies to repair or regenerate vasculatures thereby establishing more competent microcirculatory beds. Growing evidence indicates that an increase in vessel numbers within a tissue does not necessarily promote an increase in tissue perfusion. Effective regeneration of a microcirculation entails the integration of new stable microvessel segments into the network via neovascularization. Beginning with angiogenesis, neovascularization entails an integrated series of vascular activities leading to the formation of a new mature microcirculation and includes vascular guidance and inosculation, vessel maturation, pruning, arterio-venous specification, network patterning, structural adaptation, intussusception, and microvascular stabilization. While the generation of new vessel segments is necessary to expand a network, without the concomitant neovessel remodeling and adaptation processes intrinsic to microvascular network formation, these additional vessel segments give rise to a dysfunctional microcirculation. While many of the mechanisms regulating angiogenesis have been detailed, a thorough understanding of the mechanisms driving post-angiogenesis activities specific to neovascularization has yet to be fully realized, but is necessary in order to develop effective therapeutic strategies for repairing compromised microcirculations as a means to treat disease.

    A post-test analysis of a set of inside-diameter/outside-diameter (ID/OD) bidirectional brush seals used in three-port wave rotor tests was undertaken to determine brush bristle and configuration wear, pullout, and rotor coating wear. The results suggest that sharp changes in the pressure profiles were not well reflected in bristle tip configuration patterns or wear. Also, positive-to-negative changes in axial pressure gradients appeared to have little effect on the backing plates. Although the brushes had similar porosities, they had very different unpacked arrays. This difference could explain the departure of experimental data from computational fluid dynamics flow predictions for well-packed arrays at higher pressure drops. The rotor wear led to "car-track" scars (upper and lower wear bands) with a whipped surface between the bands. Those bands may have resulted from bristle stiffening at the fence and gap plates during alternate portions of the rotor cycle. Within the bristle response range the wear surface reflected the pressure distribution effect on bristle motion. No sacrificial metallurgical data were taken. The bristles did wear, with correspondingly more wear on the ID brush configurations than on the OD configurations; the complexity in constructing the ID brush was a factor.

    Antiretroviral therapy (ART) for HIV is not a cure. However, recent studies suggest that ART, initiated early during primary infection, may induce post-treatment control (PTC) of HIV infection with HIV RNA maintained at <50 copies per mL. We investigate the hypothesis that ART initiated early during primary infection permits PTC by limiting the size of the latent reservoir, which, if small enough at treatment termination, may allow the adaptive immune response to prevent viral rebound (VR) and control infection. We use a mathematical model of within host HIV dynamics to capture interactions among target cells, productively infected cells, latently infected cells, virus, and cytotoxic T lymphocytes (CTLs). Analysis of our model reveals a range in CTL response strengths where a patient may show either VR or PTC, depending on the size of the latent reservoir at treatment termination. Below this range, patients will always rebound, whereas above this range, patients are predicted to behave like elite controllers. Using data on latent reservoir sizes in patients treated during primary infection, we also predict population-level VR times for noncontrollers consistent with observations. PMID:25870266

    An experimental technique was developed for measuring post-shock temperatures in a wide variety of materials, including those of geophysical interest such as silicates. The technique uses an infrared radiation detector to determine the brightness temperature of samples shocked to pressures in the range 5 to approximately 30 GPa; in these experiments measurements were made in two wavelength ranges (4.5 to 5.75 microns and 7 to 14 microns). Reproducible results, with the temperatures in the two wavelength bands generally in excellent agreement, were obtained for aluminum-2024 (10.5 to 33 GPa, 125 to 260 C), stainless steel-304 (11.5 to 50 GPa, 80 to 350 C), crystalline quartz (5.0 to 21.5 GPa, 80 to 250 C), forsterite (7.5 to 28.0 GPa, approximately 30 to 160 C) and Bamble bronzite (6.0 to 26.0 GPa, approximately 30 to 225 C). It is concluded that release adiabat data should be used, wherever available, for calculations of residual temperature, and that adequate descriptions of the shock and release processes in minerals are more complex than generally assumed.

    Presented in this paper are the plan, equipment, procedures, and findings of an experimental investigation of the tolerance to low velocity impact of a graphite epoxy (AS4/3501-6) and graphite bismaleimide (M6/CYCOM3100) advanced composites. The applied impacts were governed by the Air Force Guide Specification 87221. Specimens of each material system having a common nominal layup (10% 0 deg; 80% +/-45 deg; 10% 90 deg), a common 7 inch (17.78 cm) by 10 inch (25.40 cm) size, five different thicknesses (9, 26, 48, 74, and 96 plies), and ambient moisture content were impacted and strength tested at room temperature. Damaged areas and post impact compression strengths (PICS) were among the most significant findings obtained. While the undamaged per ply compression strength of both materials is a strong function of laminate thickness, the per ply PICS is not. The average difference in per ply PICS between the two material systems is about seven percent. Although a smaller percentage of the applied kinetic energy was absorbed by the Gr/BMI than by the Gr/Epoxy composites, larger damaged areas were produced in the Gr/BMI than in Gr/Epoxy. Within the limitations of this investigation, the Gr/BMI system seems to offer no advantage in damage tolerance over the Gr/Epoxy system examined.

  5. The effects of post combustion and post combustion gases in the electric arc furnace

    NASA Astrophysics Data System (ADS)

    Eastep, Lisa Nicole

    In order to decrease energy consumption and increase scrap melting and productivity, post combustion (PC) technology is being implemented in several steelmaking processes, including bath smelting, the BOF and the EAF. In order to get the full benefit from this technology, the principles that govern it and the effects, both beneficial and adverse, must be determined. To this end, the CISR has been investigating two PC processes in the. EAF, the foamy slag approach and free space approach and the oxidation of scrap by post combustion gases. The free space approach, which is the subject of this work, consists of injectors blowing PC oxygen into the upper portion of the furnace. Air Liquide is developing an example of this system. Post Combustion consists of two sets of reactions: (1) the combustion of CO with oxygen and (2) the oxidation of scrap, liquid iron and C by the CO2 (the "de-post combustion" reactions). This project consists of two parts investigating both types of reactions. A computer simulation of a free space PC system is being developed and the kinetics of the oxidation of solid iron by CO 2 are being measured at high temperatures. Initial work included computer simulations of the process assuming a two-dimension geometry. These two dimension models were beneficial in gaining experience with the computer software package and provided some insights into the PC process. However, they could not adequately describe the conditions in the furnace. Therefore, a three-dimension model has been developed. Computer simulations including the post combustion reaction of CO and O2 combining to form CO2 and the de-post combustion reaction between CO2 and the carbon present in the bath have been conducted. It was found that the post combustion ratio (PCR) increased with increasing exhaust temperatures and with an increase in oxygen flow rate. Also, when the oxygen was injected at a lower flow rate with an angle, bands of temperature and composition results with the highest temperatures, and the highest concentration of CO2, occurred in a band near the injector. Finally, the temperatures near the bath surface increased as the injectors were placed closer to the bath surface. Where as the present model had several limitations and did not take into account all major factors, it did give useful insights and showed that this type of modeling is beneficial. The oxidation rate of solid iron by CO2, was measured using thermo-gravinometric analysis in conjunction with the impinging jet design to reduce the effects of gas phase mass transfer. Experiments were conducted in the temperature range of 1000--1500C with a reacting gas mixture ranging from 50% CO2--80% CO2 (remainder CO) and a dilute mixture of 800%Ar, 10% CO2 and 10% CO. The calculated kinetic rate constants were consistent with those found by previous researchers at lower temperatures. The calculated activation energy of 39.7 kcal/mole is in reasonable agreement with the published quantity of 44.3 kcal/mole, calculated by Grabke. The technique used in the present study allowed for a more accurate determination of the chemical rate at high temperatures.

    Retrospective group study on post-thymectomy myasthenia gravis (post-Tm MG) was carried out. Five hundred and twenty-seven resected thymoma cases (133 cases with MG and 394 cases without MG) were collected from 9 hospitals. Post-Tmx MG occurred in 18 out of 394 cases -4.6% of thymoma without MG-, and these 18 patients with post-Tmx MG were investigated retrospectively. As to surgical procedures, the mode of operation, either thymectomy or thymo-thymectomy was not thought to be an important factor in the pathogenesis of post-Tmx MG. These 18 patients could be divided into 7 with early onset and 11 with late onset. In the early onset group, post-Tmx MG occurred within 6 months after the operation, and these 7 patients may have had subclinical MG at the time of the initial operation. In the late onset group, post-Tmx MG was noted in 5 patients when recurrence of the tumor was confirmed, the latest being 11 years after operation. The pathogenesis of post-Tmx MG could not be clarified in the other 6 patients (33.3%). For further evaluation of these 6 cases, a prospective studies with large scale are needed. PMID:1593157
