    The caesarean section rate has continued to increase in most industrialised countries, which raises a number of economic concerns. This review provides an overview of the health economic implications of elective caesarean section. It provides a succinct summary of the health consequences associated with elective caesarean section for both the infant and the mother over the perinatal period and beyond. It highlights factors that complicate our understanding of the health consequences of elective caesarean section, including inconsistencies in definitions and coding of the procedure, failure to adopt an intention-to-treat principle when drawing comparisons, and the widespread reliance on observational data. The paper then summarises the economic costs associated with elective caesarean section. Evidence is presented to suggest that planned caesarean section may be less costly than planned vaginal birth in some clinical contexts, for example where the singleton fetus lies in a breech position at term. In contrast, elective caesarean section (or caesarean section as a whole) appears to be more costly than vaginal delivery (either spontaneous or instrumented) in low-risk or unselected populations. The paper proceeds with an overview of economic evaluations associated with elective caesarean section. All are currently based on decision-analytic models. Evidence is presented to suggest that planned trial of labour (attempted vaginal birth) following a previous caesarean section appears to be a more cost-effective option than elective caesarean section, although its cost effectiveness is dependent upon the probability of successful vaginal delivery. There is conflicting evidence on the cost effectiveness of maternal request caesareans when compared with trial of labour. The paucity of evidence on the value pregnant women, clinicians and other groups in society place on the option of elective caesarean section is highlighted. Techniques that might be used to elicit

    2014-01-01

    There has recently been a resurgence of interest in Sluggish Cognitive Tempo (SCT) as an important construct in the field of abnormal child psychology. Characterized by drowsiness, daydreaming, lethargy, mental confusion, and slowed thinking/behavior, SCT has primarily been studied as a feature of Attention-Deficit/Hyperactivity Disorder (ADHD), and namely the predominately inattentive subtype/presentation. Although SCT is strongly associated with ADHD inattention, research increasingly supports the possibility that SCT is distinct from ADHD or perhaps a different mental health condition altogether, with unique relations to child and adolescent psychosocial adjustment. This introductory article to the Special Section on SCT provides an historical overview of the SCT construct and briefly describes the contributions of the eight empirical papers included in the Special Section. Given the emerging importance of SCT for abnormal psychology and clinical science, there is a clear need for additional studies that examine (1) the measurement, structure, and multidimensional nature of SCT, (2) SCT as statistically distinct from not only ADHD-inattention but also other psychopathologies (particularly depression and anxiety), (3) genetic and environmental contributions to the development of SCT symptoms, and (4) functional impairments associated with SCT. This Special Section brings together papers to advance the current knowledge related to these issues as well as to spur research in this exciting and expanding area of abnormal psychology.

    Full Text Available BACKGROUND: As smoking is a major risk factor in India, the objective of present study was to assess smoking patterns, expenditure and awareness amongst smokers and to examine factors associated with the severity of smoking in Surat city.METHODS: Community-based cross-sectional study was conducted with the use of pre-structured questionnaire tool targeting 281 current smokers in the slums of 20 Urban Health Centers. Smokers were categorized based on pack-years, which means the number of packs smoked per day multiplied by the duration of smoking (mild 15, and based on the number of cigarette/bidis smoked per day without the duration component (mild 0.05. With the influence of friends (50%, about 60% smokers engage into this habit before the age of 20 years. Though only 20% of current smokers were not aware of the consequences of active smoking, more than 50% did not know about the same for passive smoking. The lowest socioeconomic class spends 44% of their income on tobacco products compared to 7% in the highest class.CONCLUSION: The study provides insights for information, education and counseling (IEC activities which should take into account health impact of bidi smoking, low awareness of health impact of passive smoking, and higher percentage of total monthly expenditure on tobacco among low-income household resulting in crowding out of expenditures on other needs.

  11. Consultation draft: Site characterization plan overview, Deaf Smith County Site, Texas: Nuclear Waste Policy Act (Section 113)

    Energy Technology Data Exchange (ETDEWEB)

    1988-01-01

    The Department of Energy (DOE) is preparing a site characterization plan for the candidate site in Deaf Smith County, Texas. The DOE has provided, for information and review, a consultation draft of the plan to the State of Texas and the US Nuclear Regulatory Commission. The site characterization plan is a lengthy document that describes in considerable detail the program that will be conducted to characterize the geologic, hydrologic, and other conditions relevant to the suitability of the site for a repository. The overview presented here consists of brief summaries of important topics covered in the consultation draft of the site characterization plan; it is not a substitute for the site characterization plan. The arrangement of the overview is similar to that of the plan itself, with brief descriptions of the repository system - the site, the repository, and the waste package - preceding the discussion of the characterization program to be carried out at the Deaf Smith County site. It is intended primarily for the management staff of organizations involved in the DOE's repository program or other persons who might wish to understand the general scope of the site-characterization program, the activities to be conducted, and the facilities to be constructed rather than the technical details of site characterization. 15 figs., 1 tab.

  12. FORCEFUL ARRESTS: AN OVERVIEW OF SECTION 49 OF THE CRIMINAL PROCEDURE ACT 51 OF 1977 AND ITS RECENT AMENDMENTS

    Directory of Open Access Journals (Sweden)

    2012-08-01

    Full Text Available The debate concerning the use of violence by the police force is an endless one. Section 49 of the Criminal Procedure Act 51 of 1977 serves as a framework for the use of violence by police officers during arrests in South Africa. While some hold the opinion that the powers of the police in this respect should be restricted, others see the 2003 redefined section 49 as a legislative guarantee of a suspect’s right to flee. Against this background this article has as its focus a critical discussion of the historical development of section 49 as well as the recent amendments of the same. The current legal position in South Africa is also compared with that in the United States of America as well as in the United Kingdom. Finally, certain conclusions and recommendations are made in order to enhance more favourable regulation of the employment of force in effecting arrests.

    Psoriasis is a common, chronic, inflammatory, multisystem disease with predominantly skin and joint manifestations affecting approximately 2% of the population. In this second of 5 sections of the guidelines of care for psoriasis, we give an overview of psoriatic arthritis including its cardinal clinical features, pathogenesis, prognosis, classification, assessment tools used to evaluate psoriatic arthritis, and the approach to treatment. Although patients with mild to moderate psoriatic arthritis may be treated with nonsteroidal anti-inflammatory drugs and/or intra-articular steroid injections, the use of disease-modifying antirheumatic drugs, particularly methotrexate, along with the biologic agents, are considered the standard of care in patients with more significant psoriatic arthritis. We will discuss the use of disease-modifying antirheumatic drugs and the biologic therapies in the treatment of patients with moderate to severe psoriatic arthritis.

    Phoenix, the first Mars Scout mission, capitalizes on the large NASA investments in the Mars Polar Lander and the Mars Surveyor 2001 missions. On 4 August 2007, Phoenix was launched to Mars from Cape Canaveral, Florida, on a Delta 2 launch vehicle. The heritage derived from the canceled 2001 lander with a science payload inherited from MPL and 2001 instruments gives significant advantages. To manage, build, and test the spacecraft and its instruments, a partnership has been forged between the Jet Propulsion Laboratory, the University of Arizona (home institution of principal investigator P. H. Smith), and Lockheed Martin in Denver; instrument and scientific contributions from Canada and Europe have augmented the mission. The science mission focuses on providing the ground truth for the 2002 Odyssey discovery of massive ice deposits hidden under surface soils in the circumpolar regions. The science objectives, the instrument suite, and the measurements needed to meet the objectives are briefly described here with reference made to more complete instrument papers included in this special section. The choice of a landing site in the vicinity of 68°N and 233°E balances scientific value and landing safety. Phoenix will land on 25 May 2008 during a complex entry, descent, and landing sequence using pulsed thrusters as the final braking strategy. After a safe landing, twin fan-like solar panels are unfurled and provide the energy needed for the mission. Throughout the 90-sol primary mission, activities are planned on a tactical basis by the science team; their requests are passed to an uplink team of sequencing engineers for translation to spacecraft commands. Commands are transmitted each Martian morning through the Deep Space Network by way of a Mars orbiter to the spacecraft. Data are returned at the end of the Martian day by the same path. Satisfying the mission's goals requires digging and providing samples of interesting layers to three on-deck instruments. By

    Research activity of the Department of the Theoretical Physics spans a wide variety of problems in theoretical high-energy and elementary particle physics, theoretical nuclear physics, theory of the nuclear matter, quark gluon plasma and relativistic heavy-ion collisions, theoretical astrophysics, as well as general physics. Theoretical research in high energy and elementary particle physics is concentrated on the theory of deep inelastic lepton scattering in the region of low x and its phenomenological implication for the ep collider HERA at DESY, on the theory of nonleptonic decays of hadrons, and on low energy {pi}{pi} and K-anti-K interactions and scalar meson spectroscopy. The activity in the theory of relativistic heavy-ion collisions is focused on the study of quark condensate fluctuations, on the analysis of critical scattering near the chiral phase transition, and on Bose-Einstein correlation in heavy-ion collisions. Theoretical studies in nuclear physics and in theory of nuclear matter concern analysis of models, with dynamical symmetry based on group S{sub p}(6,R) for the description of collective modes of atomic nuclei, analysis of the Goldstone bosons in nuclear matter and analysis of saturation properties of nuclear matter. Research in theoretical astrophysics is mainly devoted to the analysis of magnetic properties of hadronic matter in neutron stars with proton admixture. Studies in general physics concern problem related to the Galilean covariance of classical and quantum mechanics. The detailed results obtained in various fields are summarised in presented abstracts as well as information about employed personnel, publications, contribution to conferences, reports, workshops and seminars.

    The 1994 year activity in the Nuclear Spectroscopy Department was like in previous years spread over large variety of subjects concerned with the in-beam nuclear spectroscopy and many nucleon transfer reactions, properties of high excited nuclear states, and the applied nuclear spectroscopy. The studies in the first two groups were mostly carried out in a vast international collaboration which enabled us to carry out experiments on highly sophisticated experimental facilities abroad like EUROGAM, GASP, HECTOR or OSIRIS, and others. Some preparations for `home` experiments have been carried out on the very much looked forward and recently obtained heavy ion beam from the cyclotron at the Warsaw University. The applied nuclear spectroscopy works, on the other hand, were based on using our own installations: an elaborated set-up for perturbed angular correlations, the RBS and PIXE set-ups at the Van de Graaff accelerator, the implanter, an atomic force microscope and several others. Much of the effort manifests itself in several valuable results which are summarized in the following pages. It is to be underlined that those results, as well as some new instrumentation developments were possible due to additional support via special grants and the promotion of the international cooperation by the State Committee for Scientific Research (KBN).

    2014-07-01

    This paper gives an overview of the CARMENES instrument and of the survey that will be carried out with it during the first years of operation. CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectrographs) is a next-generation radial-velocity instrument under construction for the 3.5m telescope at the Calar Alto Observatory by a consortium of eleven Spanish and German institutions. The scientific goal of the project is conducting a 600-night exoplanet survey targeting ~ 300 M dwarfs with the completed instrument. The CARMENES instrument consists of two separate echelle spectrographs covering the wavelength range from 0.55 to 1.7 μm at a spectral resolution of R = 82,000, fed by fibers from the Cassegrain focus of the telescope. The spectrographs are housed in vacuum tanks providing the temperature-stabilized environments necessary to enable a 1 m/s radial velocity precision employing a simultaneous calibration with an emission-line lamp or with a Fabry-Perot etalon. For mid-M to late-M spectral types, the wavelength range around 1.0 μm (Y band) is the most important wavelength region for radial velocity work. Therefore, the efficiency of CARMENES has been optimized in this range. The CARMENES instrument consists of two spectrographs, one equipped with a 4k x 4k pixel CCD for the range 0.55 - 1.05 μm, and one with two 2k x 2k pixel HgCdTe detectors for the range from 0.95 - 1.7μm. Each spectrograph will be coupled to the 3.5m telescope with two optical fibers, one for the target, and one for calibration light. The front end contains a dichroic beam splitter and an atmospheric dispersion corrector, to feed the light into the fibers leading to the spectrographs. Guiding is performed with a separate camera; on-axis as well as off-axis guiding modes are implemented. Fibers with octagonal cross-section are employed to ensure good stability of the output in the presence of residual guiding errors. The

    A warm and early October afternoon saw the beginning of the 2005 ATLAS overview week, which took place Rue de La Montagne Sainte-Geneviève in the heart of the Quartier Latin in Paris. All visitors had been warned many times by the ATLAS management and the organisers that the premises would be the subject of strict security clearance because of the "plan Vigipirate", which remains at some level of alert in all public buildings across France. The public building in question is now part of the Ministère de La Recherche, but used to host one of the so-called French "Grandes Ecoles", called l'Ecole Polytechnique (in France there is only one Ecole Polytechnique, whereas there are two in Switzerland) until the end of the seventies, a little while after it opened its doors also to women. In fact, the setting chosen for this ATLAS overview week by our hosts from LPNHE Paris has turned out to be ideal and the security was never an ordeal.

    During this early stage of construction of the Large Synoptic Survey Telescope (LSST), modeling has become a crucial system engineering process to ensure that the final detailed design of all the sub-systems that compose the telescope meet requirements and interfaces. Modeling includes multiple tools and types of analyses that are performed to address specific technical issues. Three-dimensional (3D) Computeraided Design (CAD) modeling has become central for controlling interfaces between subsystems and identifying potential interferences. The LSST Telescope dynamic requirements are challenging because of the nature of the LSST survey which requires a high cadence of rapid slews and short settling times. The combination of finite element methods (FEM), coupled with control system dynamic analysis, provides a method to validate these specifications. An overview of these modeling activities is reported in this paper including specific cases that illustrate its impact.

  5. Theory overview on spectroscopy

    A theoretical overview of the exotic spectroscopy in the charm and beauty quark sector is presented. These states are unexpected harvest from the e{sup +}e{sup -} and hadron colliders and a permanent abode for the majority of them has yet to be found. We argue that some of these states, in particular the Y{sub b}(10890) and the recently discovered states Z{sub b}(10610) and Z{sub b}(10650), discovered by the Belle collaboration are excellent candidates for tetraquark states [bq][ anti b anti q], with q=u,d light quarks. Theoretical analyses of the Belle data carried out in the tetraquark context is reviewed. (orig.)

    'H2@Scale' is an opportunity for wide-scale use of hydrogen as an intermediate that carries energy from various production options to multiple uses. It is based on identifying and developing opportunities for low-cost hydrogen production and investigating opportunities for using that hydrogen across the electricity, industrial, and transportation sectors. One of the key production opportunities is use of low-cost electricity that may be generated under high penetrations of variable renewable generators such as wind and solar photovoltaics. The technical potential demand for hydrogen across the sectors is 60 million metric tons per year. The U.S. has sufficient domestic renewable resources so that each could meet that demand and could readily meet the demand using a portfolio of generation options. This presentation provides an overview of the concept and the technical potential demand and resources. It also motivates analysis and research on H2@Scale.

    Highlights: • Manufacturing status of one of the largest and the heaviest fully welded stainless steel vacuum chambers in the world (ITER Cryostat). • Overview of manufacturing stages and its segmentation. • Overview of manufacturing procedures and assembly and installation. - Abstract: One of ITER-India's commitments to the ITER Organization is procurement of the ITER Cryostat. It is a large vacuum vessel (∼29 m dia. and ∼29 m height), which is made up of 304/304 L dual marked stainless steel and has a total mass over 3500 t. The thickness of the vessel wall varies from 50 mm to 190 mm. It is one of the largest and the heaviest fully welded stainless steel vacuum chambers in the world which provides vacuum thermal insulation for the superconducting magnets operating at 4.5 K and for the thermal shield operating at 80 K. It also mechanically supports the magnet system along with the vacuum vessel (VV). The cryostat is designed and constructed according to ASME Section-VIII Division-2 with additional ITER Vacuum Handbook requirements and it is classified as protection important component (PIC-2). Manufacturing of cryostat segments is ongoing in India; sub-assembly of four major sections of the cryostat from the segments will be done at the ITER site in a temporary workshop building and the final assembly will be done in the pit of the tokamak building, the final location. The cryostat manufacturing contract has been awarded to Larsen and Toubro Limited in August 2012 after completion of design [4] and signing of Procurement Arrangement [1] with ITER Organization. Manufacturing of the cryostat was started in January 2014 after approval of the manufacturing drawings and procedures. The temporary workshop of 44 m × 110 m × 26 m in height has been completed in November 2014 at the ITER site with a 200 t crane installed. This paper gives an overview and the status of the cryostat manufacturing.

  15. Marfan's syndrome: an overview

    Directory of Open Access Journals (Sweden)

    Shi-Min Yuan

    Full Text Available Marfan's syndrome is an autosomal dominant condition with an estimated prevalence of one in 10,000 to 20,000 individuals. This rare hereditary connective tissue disorder affects many parts of the body. The diagnosis of Marfan's syndrome is established in accordance with a review of the diagnostic criteria, known as the Ghent nosology, through a comprehensive assessment largely based on a combination of major and minor clinical manifestations in various organ systems and the family history. Aortic root dilation and mitral valve prolapse are the main presentations among the cardiovascular malformations of Marfan's syndrome. The pathogenesis of Marfan's syndrome has not been fully elucidated. However, fibrillin-1 gene mutations are believed to exert a dominant negative effect. Therefore, Marfan's syndrome is termed a fibrillinopathy, along with other connective tissue disorders with subtle differences in clinical manifestations. The treatment may include prophylactic β-blockers and angiotensin II-receptor blockers in order to slow down the dilation of the ascending aorta, and prophylactic aortic surgery. Importantly, β-blocker therapy may reduce TGF-β activation, which has been recognized as a contributory factor in Marfan's syndrome. The present article aims to provide an overview of this rare hereditary disorder.

    Science.gov (United States)

    Chen, Jiang-Fan; Lee, Chien-fei; Chern, Yijuang

    2014-01-01

    Adenosine is a naturally occurring nucleoside that is distributed ubiquitously throughout the body as a metabolic intermediary. In the brain, adenosine functions as an important upstream neuromodulator of a broad spectrum of neurotransmitters, receptors, and signaling pathways. By acting through four G-protein-coupled receptors, adenosine contributes critically to homeostasis and neuromodulatory control of a variety of normal and abnormal brain functions, ranging from synaptic plasticity, to cognition, to sleep, to motor activity to neuroinflammation, and cell death. This review begun with an overview of the gene and genome structure and the expression pattern of adenosine receptors (ARs). We feature several new developments over the past decade in our understanding of AR functions in the brain, with special focus on the identification and characterization of canonical and noncanonical signaling pathways of ARs. We provide an update on functional insights from complementary genetic-knockout and pharmacological studies on the AR control of various brain functions. We also highlight several novel and recent developments of AR neurobiology, including (i) recent breakthrough in high resolution of three-dimension structure of adenosine A2A receptors (A2ARs) in several functional status, (ii) receptor-receptor heterodimerization, (iii) AR function in glial cells, and (iv) the druggability of AR. We concluded the review with the contention that these new developments extend and strengthen the support for A1 and A2ARs in brain as therapeutic targets for neurologic and psychiatric diseases.

    Neurosurgical treatment for psychiatric disorders has a long and controversial history. From the Stone Age use of trephining to release the demons of the spirit to the millimeter accuracy of stereotactic instruments currently used in the operating room, psychosurgery has enjoyed enthusiastic support as well as experiencing scorn. Today, psychosurgery is a minimally invasive and highly selective treatment that is performed for only a few patients with severe, treatment-refractory, affective, anxiety, or obsessive-compulsive disorders. Recent advances in technology and functional neuroanatomic techniques, as well as economic pressures to decrease the costs of caring for chronically ill patients, may provide an opportunity for psychosurgery to become a more attractive option for the treatment of psychiatric diseases. In this historical overview, the rise and fall of psychosurgery are described. A better understanding of the colorful history of this interesting topic should enable modern neurosurgeons and other health care professionals to meet the social, ethical, and technical challenges that are sure to lie ahead.

    The Trilinos Project is an effort to facilitate the design, development, integration and ongoing support of mathematical software libraries. In particular, our goal is to develop parallel solver algorithms and libraries within an object-oriented software framework for the solution of large-scale, complex multi-physics engineering and scientific applications. Our emphasis is on developing robust, scalable algorithms in a software framework, using abstract interfaces for flexible interoperability of components while providing a full-featured set of concrete classes that implement all abstract interfaces. Trilinos uses a two-level software structure designed around collections of packages. A Trilinos package is an integral unit usually developed by a small team of experts in a particular algorithms area such as algebraic preconditioners, nonlinear solvers, etc. Packages exist underneath the Trilinos top level, which provides a common look-and-feel, including configuration, documentation, licensing, and bug-tracking. Trilinos packages are primarily written in C++, but provide some C and Fortran user interface support. We provide an open architecture that allows easy integration with other solver packages and we deliver our software to the outside community via the Gnu Lesser General Public License (LGPL). This report provides an overview of Trilinos, discussing the objectives, history, current development and future plans of the project.

  19. Cold electronics: an overview

    Science.gov (United States)

    Kirschman, R. K.

    Low-temperature operation is being applied and contemplated for electronic systems ranging from single-transistor circuits for basic research to VLSI integrated circuits for ultra-fast computers. It is seen as both a means of extracting better performance from present technology and as an important ingredient of the next generation of devices and circuits. This overview is concerned with electronics based on semiconductors; for low temperatures the primary material is Si, although GaAs also has considerable potential, and the primary device is the field-effect transistor in various forms. Reduced temperature operation offers improvements in performance through improvement of materials-related properties such as electronic carrier mobility, thermal conductivity, and electrical conductivity. Substantial improvements in reliability are also expected since degradation mechanisms are thermally activated; however, this could be negated unless problems of thermal expansion mismatch and cycling are overcome. Refrigeration continues to be a central concern; mechanical cycles are still the mainstay and progress is being made in systems applicable to electronics, although further development is needed.

    Prassinos, Peter G.; Lyver, John W., IV; Bui, Chinh T.

    2011-01-01

    Risk assessment is used in many industries to identify and manage risks. Initially developed for use on aeronautical and nuclear systems, risk assessment has been applied to transportation, chemical, computer, financial, and security systems among others. It is used to gain an understanding of the weaknesses or vulnerabilities in a system so modification can be made to increase operability, efficiency, and safety and to reduce failure and down-time. Risk assessment results are primary inputs to risk-informed decision making; where risk information including uncertainty is used along with other pertinent information to assist management in the decision-making process. Therefore, to be useful, a risk assessment must be directed at specific objectives. As the world embraces the globalization of trade and manufacturing, understanding the associated risk become important to decision making. Applying risk assessment techniques to a global system of development, manufacturing, and transportation can provide insight into how the system can fail, the likelihood of system failure and the consequences of system failure. The risk assessment can identify those elements that contribute most to risk and identify measures to prevent and mitigate failures, disruptions, and damaging outcomes. In addition, risk associated with public and environment impact can be identified. The risk insights gained can be applied to making decisions concerning suitable development and manufacturing locations, supply chains, and transportation strategies. While risk assessment has been mostly applied to mechanical and electrical systems, the concepts and techniques can be applied across other systems and activities. This paper provides a basic overview of the development of a risk assessment.

    2016-03-01

    In emergency departments, patients present with different severities of diseases and traumatic injuries. However, patients with severe and life-threatening conditions compete for the same resources such as personal and structure. As a general rule, each patient should receive immediate diagnostic and treatment, independent of his or her severity of disease or traumatic injury. However, an unexpected number of patients presenting to the emergency department at the same time may exceed available resources. Thus, waiting times will occur and management of patients may be impeded. As a consequence, patients with diseases or traumatic injuries with a need for time-critical management, have to be detected at the time of presentation. After categorization, patients have to be prioritized and guided to the correct place of treatment ("triage"). Starting in Australia and the United States, nurse-driven triage systems have been introduced in the emergency departments. Aim of triage is to correctly identify at increased risk of death and guide them to rapid and correct treatment. In Germany, two five-level triage systems have been introduced: Manchester Triage System (MTS) and Emergency Severity Index (ESI). We give an overview of these risk assessment tools and discuss pros and cons. In addition, new options such as "team triage" and a combination with "Early Warning Scores" are reported. In summary, nurse-driven triage is an instrument to improve patient safety in emergency medicine. A structured and systematic triage of patients using validated triage assessment tools are recommended from national and international societies of emergency medicine. Therefore, nurse-driven triage is also a must in Germany.

    NASA s Constellation Program employs a strategic analysis methodology in providing an integrated analysis capability of Lunar exploration scenarios and to support strategic decision-making regarding those scenarios. The strategic analysis methodology integrates the assessment of the major contributors to strategic objective satisfaction performance, affordability, and risk and captures the linkages and feedbacks between all three components. Strategic analysis supports strategic decision making by senior management through comparable analysis of alternative strategies, provision of a consistent set of high level value metrics, and the enabling of cost-benefit analysis. The tools developed to implement the strategic analysis methodology are not element design and sizing tools. Rather, these models evaluate strategic performance using predefined elements, imported into a library from expert-driven design/sizing tools or expert analysis. Specific components of the strategic analysis tool set include scenario definition, requirements generation, mission manifesting, scenario lifecycle costing, crew time analysis, objective satisfaction benefit, risk analysis, and probabilistic evaluation. Results from all components of strategic analysis are evaluated a set of pre-defined figures of merit (FOMs). These FOMs capture the high-level strategic characteristics of all scenarios and facilitate direct comparison of options. The strategic analysis methodology that is described in this paper has previously been applied to the Space Shuttle and International Space Station Programs and is now being used to support the development of the baseline Constellation Program lunar architecture. This paper will present an overview of the strategic analysis methodology and will present sample results from the application of the strategic analysis methodology to the Constellation Program lunar architecture.

    Over the last 10-15 years, significant advances have been made in information management, there are an increasing number of individuals entering the field of information management as it applies to Geoscience and Remote Sensing data, and the field of informatics has come to its own. Informatics is the science and technology of applying computers and computational methods to the systematic analysis, management, interchange, and representation of science data, information, and knowledge. Informatics also includes the use of computers and computational methods to support decision making and applications. Earth Science Informatics (ESI, a.k.a. geoinformatics) is the application of informatics in the Earth science domain. ESI is a rapidly developing discipline integrating computer science, information science, and Earth science. Major national and international research and infrastructure projects in ESI have been carried out or are on-going. Notable among these are: the Global Earth Observation System of Systems (GEOSS), the European Commissions INSPIRE, the U.S. NSDI and Geospatial One-Stop, the NASA EOSDIS, and the NSF DataONE, EarthCube and Cyberinfrastructure for Geoinformatics. More than 18 departments and agencies in the U.S. federal government have been active in Earth science informatics. All major space agencies in the world, have been involved in ESI research and application activities. In the United States, the Federation of Earth Science Information Partners (ESIP), whose membership includes over 180 organizations (government, academic and commercial) dedicated to managing, delivering and applying Earth science data, has been working on many ESI topics since 1998. The Committee on Earth Observation Satellites (CEOS)s Working Group on Information Systems and Services (WGISS) has been actively coordinating the ESI activities among the space agencies.The talk will present an overview of current efforts in ESI, the role members of IEEE GRSS play, and discuss

    2012-02-01

    Full Text Available Drug development technologies constituting innovations at the formulation end in the Pharmaceutical industry has received a lot of attention in past two decades. Drug delivery as an opportunity to extend product life cycles has indeed proved its place in the market with significant advantages of therapeutic gains as well as commercial success. Carrier technology offers an intelligent approach for drug delivery by coupling the drug to a carrier particle such as liposomes, microspheres, nanoparticles, etc. which modulates the release and absorption characteristics of the drug. Liposomes are well known to alter the bio distribution of entrapped substances by protecting the enclosed material. They are widely used as vehicles to target the specific molecule to specific organ. During the last few decades liposomes have attracted great interest as ideal models for biological membranes as well as efficient carriers for drugs, diagnostics, vaccines, nutrients and other bioactive agents. Many techniques and methodologies have involved for the manufacture of liposomes, on small and large scales, since their introduction to the scientific community around 40 years ago. This article intends to provide an overview of the advantages and disadvantages of liposome preparation methods,their stability, bio distribution and their uses as drug delivery systems. The conventional method of preparing liposomes is basically for the multilamellar vesicles (MLVs. However, other methods are used to reduce the size of these MLVs to small unilamellar vesicles (SUVs so as to increase their plasma lifetime and consequently increase the possibility of achieving greater tissue localisation. Some of these methods of size reduction are sonication and high pressure extrusion. Each of these methods has its own advantages and disadvantages. Large unilamellar vesicles (LUVs, on the other hand, are prepared mainly by detergent removal method and reverse phase extrusion technique. There

    The tendency of increasing cesarean section rate has drawn worldwide attention. The vaginal birth after cesarean section is a useful method to decrease cesarean section rate at defined cases. Retrospective overview of factors resulting successful vaginal birth, labor/induction's condition, criterias, short and long term benefits and consequences. Overview recommendations of international guidelines and publications' results concerned vaginal birth after cesarean section in "PubMed", "MEDLINE", "Cochrane" databases from 1996 to 2016. Reviewing results of recommendations and publications we can declare that statements are inconsistent, however the option of vaginal birth after cesarean section is appropriate for decrease complications and trend of increasing cesarean section rate. It would be important in our country to define a uniform recommendation regarding vaginal birth after cesarean section, with supporting evidence in obstetrical and gynecological practice.

    Metallothioneins(MTs)were discovered in 1957 by Margoshes and Vallee and identified as low-molecular weight and sulphydryl rich proteins.It is not surprising that most mammalian tissues contain age related basal levels of MTs since they are involved in metalloregulatory processes that include cell growth and multiplication.In an effort to understand the biology of this intriguing tumor,various biomarkers such as oncogenes,p53 tumor suppressor gene,waf 1 protein,proliferating cell nuclear antigen,telomerase,microsatellite markers and cytogenetic changes have been examined.One biomarker which has recently shown to be expressed in various human tumors but still less reported in carcinoma is MT.Immunohistochemical detection of MT proteins in cold acetone-fixed paraffin embedded liver sections was performed by the streptavidin-avidin-biotin immunoperoxidase complex method.

  15. Gas-filled separators - An overview

    CERN Document Server

    Leino, M

    2003-01-01

    Gas-filled recoil separators have been used in nuclear physics studies since the early fifties. Most notably, they have found use in the separation of evaporation residues of heavy and very heavy elements from unwanted background. Gas-filled separators, alone or coupled to a detector array, offer an efficient, fast, compact and relatively inexpensive solution for nuclear structure studies. A new application is the use of a gas-filled device as a pre-separator in the study of chemical properties of the heaviest elements. Other uses include systematic study of fusion evaporation cross sections and accelerator mass spectrometry. In this contribution, an overview on gas-filled recoil separators, their characteristics, fields of application and possible future developments is given.

    Directory of Open Access Journals (Sweden)

    Athmanathan Sreedharan

    1997-01-01

    Full Text Available Antiviral drug development has been slow due to many factors. One such factor is the difficulty to block the viral replication in the cell without adversely affecting the host cell metabolic activity. Most of the antiviral compounds are analogs of purines and pyramidines. Currently available antiviral drugs mainly inhibit viral nucleic acid synthesis, hence act only on actively replicating viruses. This article presents an overview of some of the commonly used antiviral agents in clinical ophthalmology.

    Brown, Robert H.; Lebreton, Jean-Pierre; Waite, J. Hunter

    This book is the one of two volumes meant to capture the main scientific results of the Cassini—Huygens prime mission. The first book, Saturn from Cassini—Huygens, contains the material pertinent to Saturn, its satellites and its magnetosphere, except its largest moon Titan. This book, Titan from Cassini—Huygens is meant to capture the main scien-tific results regarding Titan, including its origin and evolution, interior, surface, atmosphere and interaction with Saturn's magnetosphere. The reason we have chosen to treat the results for Titan in a separate volume is that at the time of publication of this book, the Cassini spacecraft has flown by Titan some 62 times, including delivering the Huygens probe, which successfully landed on Titan's surface and survived for over 2 hours, transmitting a wealth of data on Titan's atmosphere and surface. The scientific results obtained for Titan are so voluminous that they cannot be properly captured as part of the “Saturn from Cassini—Huygens” volume and require a separate volume; thus, the two books.

    1983-02-01

    Solanine is a toxic glycoalkaloid known to accumulate under certain conditions in potato plant, sprouts and tuber in levels which, if ingested, may cause poisoning in humans and farm animals. However, ingested solanine is relatively less toxic than the parenterally administered compound, probably because of its poor absorption, rapid excretion and hydrolysis to less toxic solanine in stomach. Nevertheless, solanine poisoning may cause a gastrointestinal, nervous and exanthematous syndrome severe enough to be fatal. Implications of solanine toxicity in farm animals and humans are discussed in this overview.

Electronic whiteboards are a means of supporting clinicians in creating and maintaining the overview necessary to provide quality treatment of patients. The concrete...... meaning of the notion of overview is, however, fussy. To explore the notion of overview and how it might be affected by whiteboards, we conducted a survey at two emergency departments and, for reasons of comparison, a pediatric department. Our results indicate that respondents consider the information...... on their dry-erase whiteboards important to their overview and that they are positive toward the introduction of electronic whiteboards. At the emergency departments, the phy-sicians’ and nurses’ overall perception of their overview correlates with different subcomponents of overview, suggesting differences...

    Foster, Terry

    1995-04-01

    With the introduction of strict environmental regulations governing the use and disposal of methylene chloride and phenols, major components of chemical paint strippers, there have been many new environmentally safe and effective methods of paint removal developed. The new methods developed for removing coatings from aircraft and aircraft components include: mechanical methods using abrasive media such as plastic, wheat starch, walnut shells, ice and dry ice, environmentally safe chemical strippers and paint softeners, and optical methods such as lasers and flash lamps. Each method has its advantages and disadvantages, and some have unique applications. For example, mechanical and abrasive methods can damage sensitive surfaces such as composite materials and strict control of blast parameters and conditions are required. Optical methods can be slow, leaving paint residues, and chemical methods may not remove all of the coating or require special coating formulations to be effective. As an introduction to environmentally safe and effective methods of paint removal, this paper is an overview of the various methods available. The purpose of this overview is to introduce the various paint removal methods available.

    Full Text Available Adel F Almutairi Population Health Research Section, King Abdullah International Medical Research Center (KAIMRC, Riyadh, Kingdom of Saudi Arabia; King Saud Bin Abdulaziz University for Health Sciences, Riyadh, Kingdom of Saudi ArabiaWhile I was reading on this topic, I came across an online article attributed to a Saudi psychologist that contained information about mental illness among the Saudi population. What really struck me right away was the estimate that was given for the number of mentally ill people in the country. It was claimed that about half of the Saudi population is suffering from mental illness.1 This made me wonder on what grounds the psychologist was basing the claim and how she came up with this scary statistic. If the figure was based on an empirical study, what was the sample size and how robust was the research? Unfortunately, no details were given to answer these questions. Nevertheless, such an alarming figure was the main impetus and driving force for me to write this article and provide readers with an overview of the magnitude of mental illness in the world, and more specifically, in the kingdom of Saudi Arabia, based on recent literature. This article also provides perspectives of scientists working at King Abdullah International Medical Research Center, on how we intend to tackle this issue.

  2. Overview of the genetic tools in the Archaea

    Directory of Open Access Journals (Sweden)

    Haruyuki eAtomi

    2012-10-01

    Full Text Available This section provides an overview of the genetic systems developed in the Archaea. Genetic manipulation is possible in many members of the halophiles, methanogens, Sulfolobus and Thermococcales. We describe the selection/counterselection principles utilized in each of these groups, which consist of antibiotics and their resistance markers, and auxotrophic host strains and complementary markers. The latter strategy utilizes techniques similar to those developed in yeast. However, Archaea are resistant to many of the antibiotics routinely used for selection in the Bacteria, and a number of strategies specific to the Archaea have been developed. In addition, examples utilizing the genetic systems developed for each group will be briefly described.

    Summary Background The number of incoming expectant women who have previously experienced cesarean section has increased. This work sought to find the frequency and connections between vaginal deliveries, cesarean sections, and iterative cesarean sections from 2004 to 2008. Material/Methods In all, 828 women with previous cesarean sections were included. From this group, 8282 vaginal deliveries were performed. During these years, 828 women had a history of the cesarean section; in these women, iterative cesarean sections were indicated. To evaluate knowledge of educational material designed for women being prepared for the iterative delivery, we used information compiled on experience from 2002 to 2003; the same approach was used to evaluate the nursing process on interventions and diagnoses of cesarean sections. Results From 2004 to 2008, 11 279 deliveries were performed in the Perinatological Center in České Budějovice; this was significant (Pcesarean section. The number of iterative cesarean sections in women who had already experienced the cesarean section (828) and delivered by cesarean section again is 620. Other data were not significant. Only 2 to 3 pregnancies next to the first cesarean section were statistically significant in 2004 and 2005. Conclusions If a trial of labor after cesarean does not proceed to vaginal birth, the woman will need support and encouragement to express feelings about another cesarean birth. PMID:21278695

    Oedegaard, Hallvard

    2003-07-01

    The management of wastewater sludge from wastewater treatment plants represents one of the major challenges in wastewater treatment today. The cost of the sludge treatment amounts to more that the cost of the liquid in many cases. Therefore the focus on and interest in sludge minimization is steadily increasing. In the paper an overview is given for sludge minimization (sludge mass reduction) options. It is demonstrated that sludge minimization may be a result of reduced production of sludge and/or disintegration processes that may take place both in the wastewater treatment stage and in the sludge stage. Various sludge disintegration technologies for sludge minimization are discussed, including mechanical methods (focusing on stirred ball-mill, high-pressure homogenizer, ultrasonic disintegrator), chemical methods (focusing on the use of ozone), physical methods (focusing on thermal and thermal/chemical hydrolysis) and biological methods (focusing on enzymatic processes).

  12. Adaptive Equalization Algorithms: An Overview

    Directory of Open Access Journals (Sweden)

    Garima Malik

    2011-03-01

    Full Text Available The recent digital transmission systems impose the application of channel equalizers with short training time and high tracking rate. Equalization techniques compensate for the time dispersion introduced by communication channels and combat the resulting inter-symbol interference (ISI effect. Given a channel of unknown impulse response, the purpose of an adaptive equalizer is to operate on the channel output such that the cascade connection of the channel and the equalizer provides an approximation to an ideal transmission medium. Typically, adaptive equalizers used in digital communications require an initial training period, during which a known data sequence is transmitted. A replica of this sequence is made available at the receiver in proper synchronism with the transmitter, thereby making it possible for adjustments to be made to the equalizer coefficients in accordance with the adaptive filtering algorithm employed in the equalizer design. In this paper, an overview of the current state of the art in adaptive equalization techniques has been presented.

  13. Overview of kaon decay physics

    CERN Document Server

    Peccei, Roberto D

    1995-01-01

    After a brief history of the insights gained from Kaon physics, the potential of Kaon decays for probing lepton number violation is discussed. Present tests of CTP and of Quantum Mechanics in the neutral Kaon sector are then reviewed and the potential of the Frascati \\Phi factory for doing incisive tests in this area is emphasized. The rest of this overview focuses on CP violating effects in the Kaon system. Although present observations of CP violation are perfectly consistent with the CKM model, we emphasize the theoretical and experimental difficulties which must be faced to establish this conclusively. In so doing, theoretical predictions and experimental prospects for detecting \\Delta S=1 CP violation through measurements of \\epsilon^\\prime/\\epsilon and of rare K decays are reviewed. The importance of looking for evidence for non-CKM CP-violating phases, through a search for a non-vanishing transverse muon polarization in K_{\\mu 3} decays, is also stressed.

    We present an overview of inflationary models derived from string theory focusing mostly on closed string moduli as inflatons. After a detailed discussion of the {eta}-problem and different approaches to address it, we describe possible ways to obtain a de Sitter vacuum with all closed string moduli stabilised. We then look for inflationary directions and present some of the most promising scenarios where the inflatons are either the real or the imaginary part of Kaehler moduli. We pay particular attention on extracting potential observable implications, showing how most of the scenarios predict negligible gravitational waves and could therefore be ruled out by the Planck satellite. We conclude by briefly mentioning some open challenges in string cosmology beyond deriving just inflation. (orig.)

    2007-01-01

    The ATLAS Overview Weeks always provide a good opportunity to see the status and progress throughout the experiment, and the July week at Glasgow University was no exception. The setting, amidst the traditional buildings of one of the UK's oldest universities, provided a nice counterpoint to all the cutting-edge research and technology being discussed. And despite predictions to the contrary, the weather at these northern latitudes was actually a great improvement on the previous few weeks in Geneva. The meeting sessions comprehensively covered the whole ATLAS project, from the subdetector and TDAQ systems and their commissioning, through to offline computing, analysis and physics. As a long-time ATLAS member who remembers plenary meetings in 1991 with 30 people drawing detector layouts on a whiteboard, the hardware and installation sessions were particularly impressive - to see how these dreams have been translated into 7000 tons of reality (and with attendant cabling, supports and services, which certainly...

    Inflammatory breast cancer (IBC) is the most aggressive entity of breast cancer. Management involves coordination of multidisciplinary management and usually includes neoadjuvant chemotherapy, ablative surgery if a tumor-free resection margin is expected and locoregional radiotherapy. This multimodal therapeutic approach has significantly improved patient survival. However, the median overall survival among women with IBC is still poor. By elucidating the biologic characteristics of IBC, new treatment options may become available. We performed a comprehensive review of the English-language literature on IBC through computerized literature searches. The objective of the current review is to present an overview of the literature related to the biology, imaging and multidisciplinary treatment of inflammatory breast cancer.

  17. An overview on selection methods

    Directory of Open Access Journals (Sweden)

    J. W. H. Swanepoel

    1982-03-01

    Full Text Available In many studies the experimenter has under consideration several (two or more alternatives, and is studying them in order to determine which is the best (with regard to certain specified criteria of “goodness”. Such an experimenter does not wish basically to test hypotheses, or construct confidence intervals, or perform regression analyses (though these may be appropriate parts of his analysis; he does wish to select the best of several alternatives, and the major part of his analysis should therefore be directed towards this goal. It is precisely for this problem that ranking and selection procedures were developed. This paper presents an overview of some recent work in this field, with emphasis on aspects important to experimenters confronted with selection problems. Fixed sample size and sequential procedures for both the indifference zone and subset formulations of the selection problem are discussed.

    Given the obvious quality of life concerns with medical and surgical lowering of intraocular pressure (IOP), lasers have received considerable attention as a therapeutic modality for glaucoma. Selective laser trabeculoplasty (SLT) is increasingly being used in clinical practice as both the primary procedure and as an adjunct to medical and surgical therapy. Preliminary published evidence suggests that SLT is an effective, compliance-free, repeatable and safe therapeutic modality having only minor, transient, self-limiting or easily controlled side effects with no sequelae. This review attempts a broad overview of the current knowledge of its mechanism, efficacy, indications and limitations, point out the knowledge lacunae that still exist with respect to this highly promising technology which has captured the attention of glaucoma surgeons all over the world.

    Full Text Available Scar formation is an inevitable consequence of wound healing from either a traumatic or a surgical intervention. The aesthetic appearance of a scar is the most important criteria to judge the surgical outcome. An understanding of the anatomy and wound healing along with experience, meticulous planning and technique can reduce complications and improve the surgical outcome. Scar revision does not erase a scar but helps to make it less noticeable and more acceptable. Both surgical and non-surgical techniques, used either alone or in combination can be used for revising a scar. In planning a scar revision surgeon should decide on when to act and the type of technique to use for scar revision to get an aesthetically pleasing outcome. This review article provides overview of methods applied for facial scar revision. This predominantly covers surgical methods.

  1. An overview of job embeddedness.

    Reitz, O Ed; Anderson, Mary Ann

    2011-01-01

    Nursing turnover in health care organizations is a considerable problem that needs to be reframed within the context of "nurse retention" and "job embeddedness" (JE). A construct from the business literature, JE has been associated with "retention" or "antiwithdrawal." Conversely, turnover encompasses the process of quitting. This distinction is significant. JE represents a mediating construct between various "on-the-job" (organizational) factors, "off-the-job" (community) factors, and employee retention. This article presents an overview of JE including the dimensions, the related concepts of turnover and retention, and associated research. JE may be used to develop specific nurse-retention strategies following careful organizational and community assessment. With the current and looming nursing shortage, perhaps it is time for health care institutions to consider the adaptation of JE tenets.

    1988-01-01

    The advent of Space Shuttle Orbital operations utilizing science and technology payloads has led to a renewal of interest of vehicle-environmental interactions in low earth orbit. The first science payload on STS-3 showed an interaction on the surface of the Orbiter which, although it had been detected earlier on unmanned spacecraft, quickened interest in the possible impact of this phenomena on future missions. Subsequent flights have yielded data on a wide variety of interaction phenomena resulting from the large size of the Orbiter and its outgassing characteristics. These drivers have given rise to modifications in the neutral gas and plasma environments of the Space Shuttle Orbiter. The physics of the interactions result in the generation of disturbed wave fields, optical emissions and particle distributions in the vicinity of the Orbiter. In this overview, the present observations, suggested interpretations and open questions will be addressed.

    Work is underway to develop a new ICF platform on the Omega and NIF facilities to better quantify the influence of heterogeneous mix on fusion burn. Results of these experiments will be compared to a probability distribution function (PDF) burn model that has been developed to address yield from separated reactant experiments. CH capsules comprised of CH or CD solid foam cores containing tritium gas are being proposed along with capsules filled with a mixture of deuterated propane and tritium gas. For configurations in which the D and T are initially spatially separated, subsequent DT yield is used to characterize the mix. An overview of the experimental concept will be presented, and simulations in preparation for the platform will be discussed. This work is supported by the US DOE performed by LANL under Contract DE-AC52-06NA25396.

    At the time of this reporting, there are 2,589 rich mobile devices used at JPL, including 1,550 iPhones and 968 Blackberrys. Considering a total JPL population of 5,961 employees, mobile applications have a total addressable market of 43 percent of the employees at JPL, and that number is rising. While it was found that no existing desktop tools can realistically be replaced by a mobile application, there is certainly a need to improve access to these desktop tools. When an alarm occurs and an engineer is away from his desk, a convenient means of accessing relevant data can save an engineer a great deal of time and improve his job efficiency. To identify which data is relevant, an engineer benefits from a succinct overview of the data housed in 13+ tools. This need can be well met by a single, rich, mobile application that provides access to desired data across tools in the ops infrastructure.

    Ranade, Vasant V; Somberg, John C

    2005-01-01

    Stereochemistry in drug molecules is rapidly becoming an important aspect in drug research, design, and development. Recently, individual stereoisomers of drug molecules with asymmetric centers such as fexofenadine, cetirizine, verapamil, fluoxetine, levalbutarol, and amphetamine, for example, have been separated and developed as individual drugs. These stereoisomers have different therapeutic activity, and each isomer has contributed differently with respect to its formulation's pharmacologic activity, side effects, and toxicity. The present overview discusses chirality among a select group of cardiovascular drugs, their stereochemical synthesis/preparation, isolation techniques using chiral chromatography, methods for confirmation of their enantiomeric purity, pharmacodynamics, and pharmacokinetics. Chirality has been visualized as an important factor in cardiovascular research. It is also becoming evident in other areas of therapeutics.

    An overview of the various tritium research and operational activities in Canada is presented. These activities encompass tritium processing and recovery, tritium interactions with materials, and tritium health and safety. Many of these on-going activities form a sound basis for the tritium use and handling aspects of the ITER project. Tritium management within the CANDU heavy water reactor, associated detritiation facilities, research and development facilities, and commercial industry and improving the understanding of tritium behaviour in humans and the environment remain the focus of a long-standing Canadian interest in tritium. While there have been changes in the application of this knowledge and experience over time, the operating experience and the supporting research and development continue to provide for improved plant and facility operations, an improved understanding of tritium safety issues, and improved products and tools that facilitate tritium management.

  16. DNA Sequencing Sensors: An Overview

    Directory of Open Access Journals (Sweden)

    Jose Antonio Garrido-Cardenas

    2017-03-01

    Full Text Available The first sequencing of a complete genome was published forty years ago by the double Nobel Prize in Chemistry winner Frederick Sanger. That corresponded to the small sized genome of a bacteriophage, but since then there have been many complex organisms whose DNA have been sequenced. This was possible thanks to continuous advances in the fields of biochemistry and molecular genetics, but also in other areas such as nanotechnology and computing. Nowadays, sequencing sensors based on genetic material have little to do with those used by Sanger. The emergence of mass sequencing sensors, or new generation sequencing (NGS meant a quantitative leap both in the volume of genetic material that was able to be sequenced in each trial, as well as in the time per run and its cost. One can envisage that incoming technologies, already known as fourth generation sequencing, will continue to cheapen the trials by increasing DNA reading lengths in each run. All of this would be impossible without sensors and detection systems becoming smaller and more precise. This article provides a comprehensive overview on sensors for DNA sequencing developed within the last 40 years.

  17. Cancer Vaccines: A Brief Overview.

    Science.gov (United States)

    Thomas, Sunil; Prendergast, George C

    2016-01-01

    Vaccine approaches for cancer differ from traditional vaccine approaches for infectious disease in tending to focus on clearing active disease rather than preventing disease. In this review, we provide a brief overview of different types of vaccines and adjuvants that have been investigated for the purpose of controlling cancer burdens in patients, some of which are approved for clinical use or in late-stage clinical trials, such as the personalized dendritic cell vaccine sipuleucel-T (Provenge) and the recombinant viral prostate cancer vaccine PSA-TRICOM (Prostvac-VF). Vaccines against human viruses implicated in the development and progression of certain cancers, such as human papillomavirus in cervical cancer, are not considered here. Cancers express "altered self" antigens that tend to induce weaker responses than the "foreign" antigens expressed by infectious agents. Thus, immune stimulants and adjuvant approaches have been explored widely. Vaccine types considered include autologous patient-derived immune cell vaccines, tumor antigen-expressing recombinant virus vaccines, peptide vaccines, DNA vaccines, and heterologous whole-cell vaccines derived from established human tumor cell lines. Opportunities to develop effective cancer vaccines may benefit from seminal recent advances in understanding how immunosuppressive barricades are erected by tumors to mediate immune escape. In particular, targeted ablation of these barricades with novel agents, such as the immune checkpoint drug ipilimumab (anti-CTLA-4) approved recently for clinical use, may offer significant leverage to vaccinologists seeking to control and prevent malignancy.

  18. An overview of health forecasting.

    Soyiri, Ireneous N; Reidpath, Daniel D

    2013-01-01

    Health forecasting is a novel area of forecasting, and a valuable tool for predicting future health events or situations such as demands for health services and healthcare needs. It facilitates preventive medicine and health care intervention strategies, by pre-informing health service providers to take appropriate mitigating actions to minimize risks and manage demand. Health forecasting requires reliable data, information and appropriate analytical tools for the prediction of specific health conditions or situations. There is no single approach to health forecasting, and so various methods have often been adopted to forecast aggregate or specific health conditions. Meanwhile, there are no defined health forecasting horizons (time frames) to match the choices of health forecasting methods/approaches that are often applied. The key principles of health forecasting have not also been adequately described to guide the process. This paper provides a brief introduction and theoretical analysis of health forecasting. It describes the key issues that are important for health forecasting, including: definitions, principles of health forecasting, and the properties of health data, which influence the choices of health forecasting methods. Other matters related to the value of health forecasting, and the general challenges associated with developing and using health forecasting services are discussed. This overview is a stimulus for further discussions on standardizing health forecasting approaches and methods that will facilitate health care and health services delivery.

  19. Friedreich's ataxia 1979: an overview.

    Barbeau, A

    1979-05-01

    This overview summarizes the investigations carried out during the second part of Phase Two of the Quebec Cooperative Study of Friedreich's Ataxia. These investigations outline in more details the fundamental role played by an abnormality in the fatty acid composition (deficient linoleic acid, 18:2) of the cholesterol esters of high density lipoproteins (HDL) in the phenotypic expression of the disease. They postulate a defective incorporation of linoleic acid to surface phosphatidylcholine of chylomicrons and consequent relative and absolute decreases in lipoprotein protein components because of overpacking with defective cholesteryl esters. Secondarily to these changes, the postulated lack of activation of the lipoamide dehydrogenase (LAD) of the pyruvate dehydrogenase (PDH) complex could result in slow pyruvate oxidation, glucose intolerance, deficient synthesis of acetylcholine, and depletion of glutamic and aspartic acid pools. In parallel, abnormal phosphatidyl-choline molecules could be incorporated to membranes, resulting in specific defects in some functions of these membranes, including transport of calcium and/or taurine and myelinization. The framework of an understanding of Friedreich's ataxia is now available, but much fundamental and clinical work remains to be done to fill in and prove each one of these postulated steps.

    Allsopp, David J.; Dibsdall, Ian M.

    2002-08-01

    This paper will present an overview and early results of the QinetiQ Portable Humanitarian Mine Detector project, funded by the UK Treasury Capital Modernization Fund. The project aims to develop a prototype multi-sensor man-portable detector for humanitarian demining, drawing on experience from work for UK MoD. The project runs from July 2000 to October 2002. The project team have visited mined areas and worked closely with a number of demining organizations and a manufacturer of metal detectors used in the field. The primary objective is to reduce the number of false alarms resulting from metallic ground clutter. An analysis of such clutter items found during actual demining has shown a large proportion to be very small when compared with anti-personnel mines. The planned system integrates: a lightweight multi-element pseudo-random-code ground penetrating radar array; a pulse induction metal detector and a capacitive sensor. Data from the GPR array and metal detector are fused to provide a simple audio-visual operator interface. The capacitive sensor provides information to aid processing of the radar responses and to provide feedback to the operator of the position of the sensors above the ground. At the time of presentation the project should be in the final stages of build, prior to tests and field trials, which QinetiQ hope to carry out under the International Test and Evaluation Project (ITEP) banner.

  1. Human saliva proteome: an overview

    Griffin, Timothy J.

    2014-06-01

    Human saliva contains a rich mixture of biomolecules. Proteins are a major component of this mixture. Given their role as the molecular effectors within biological systems, ranging from catalysis to transport to structure, proteins have great potential as biomarkers of health and disease. The ability to collect these salivary biomarkers easily using non-invasive means makes saliva proteins even more attractive for diagnostic applications. Thousands of proteins are now to be known to be present in human saliva - discovered using proteomic technologies. Emerging technologies are now making it possible to go beyond large-scale cataloging of salivary proteins. These include approaches to catalog protein contributions from the community of microorganisms residing in the oral cavity (metaproteomics) that may reflect the health state of the human host. New mass spectrometry-based proteomics methods are also emerging, shifting the emphasis from large-scale discovery experiments to hypothesis-driven assays for profiling proteins of interest within saliva, enabling validation of their association with specific health conditions. This paper provides a brief overview of efforts to catalog the proteome of human saliva. Recent developments making possible characterization of the metaproteome of human saliva will be discussed, and technologies driving new mass spectrometry-based assays for targeted analysis of proteins within complex samples, such as saliva.

    Human plague remains a public health concern in Tanzania despite its quiescence in most foci for years, considering the recurrence nature of the disease. Despite the long-standing history of this problem, there have not been recent reviews of the current knowledge on plague in Tanzania. This work aimed at providing a current overview of plague in Tanzania in terms of its introduction, potential reservoirs, possible causes of plague persistence and repeated outbreaks in the country. Plague is believed to have been introduced to Tanzania from the Middle East through Uganda with the first authentication in 1886. Xenopsylla brasiliensis, X. cheopis, Dinopsyllus lypusus, and Pulex irritans are among potential vectors while Lophuromys spp, Praomys delectorum, Graphiurus murinus, Lemniscomys striatus, Mastomys natalensis, and Rattus rattus may be the potential reservoirs. Plague persistence and repeated outbreaks in Tanzania are likely to be attributable to a complexity of factors including cultural, socio-economical, environmental and biological. Minimizing or preventing people's proximity to rodents is probably the most effective means of preventing plague outbreaks in humans in the future. In conclusion, much has been done on plague diagnosis in Tanzania. However, in order to achieve new insights into the features of plague epidemiology in the country, and to reorganize an effective control strategy, we recommend broader studies that will include the ecology of the pathogen, vectors and potential hosts, identifying the reservoirs, dynamics of infection and landscape ecology.

  3. Production excimer laser equipment overview

    Sercel, Jeffrey P.

    1993-04-01

    Excimer lasers were commercialized in the late 1970's. The laser community thought that by the early 1980's these UV lasers would enjoy a fruitful industrial market position. CO2 and solid state lasers required almost two decades to be fully accepted as industrial machine while the excimer laser was expected to be a fast learner benefiting from the learning curve of its big brothers. In retrospect, early excimer lasers had a bad reputation for being complicated, expensive and frequently out of commission. By the late 1980's a few excimer laser manufacturers had engineered the problems to acceptable levels for successful pilot lines and small scale manufacturing to begin. At this time, the real industrial learning curves began as engineers worked to refine many subsystems and support technologies. Today, excimer lasers are being used as true industrial lasers. They have a bright future with numerous and diverse market opportunities. This paper is an overview of the technologies proven to be successful in adapting modern excimer lasers to successful full production situations.

    Elkeeb, Dena; Elkeeb, Laila; Maibach, Howard

    2012-12-01

    The level of interest in photoirritation (phototoxicity) has increased because of the awareness among the scientific community of the increase in the UV portion of the solar spectrum reaching the earth. The need of new chemicals and drugs puts pressure on pre-test methods for side effects, especially interactive adverse effects with UV light. So pre-marketing clinical trials conducted before a new drug is licensed are essential, as such, at the early phases of the discovery process of the drug/chemical, developing an efficacious photosensitivity testing system is prudent to avoid such potential side effects. To review published literature and provide an overview on exogenous photosensitivity and assays used to evaluate the photosensitivity potential of drugs/chemicals. As well as testing considerations by the Regulatory bodies (namely, the Organization for Economic Cooperation and Development, the U.S Food and Drug Administration and the European Union regulatory agencies). We searched medical and scientific search engines as well as websites of the EU and US Regulatory agencies and used keywords such as cutaneous phototoxicity, phototoxicity in vitro assays, phototoxicity in vivo assays and other related terms.

  7. Social network site addiction - an overview.

    Andreassen, Cecilie Schou; Pallesen, Ståle

    2014-01-01

    Research into frequent, excessive, and compulsive social network activity has increased the last years, in which terms such as "social network site addiction" and "Facebook addiction" have been used interchangeably. The aim of this review is to offer more knowledge and better understanding of social network site addiction (SNS-addiction) among researchers as well as clinicians by presenting a narrative overview of the research field in terms of definition, measurement, antecedents, consequences, and treatment as well as recommendations for future research efforts. Seven different measures of SNS-addiction have been developed, although they have to a very little extent been validated against each other. The small number of studies conducted so far on this topic suggests that SNS-addiction is associated with health-related, academic, and interpersonal problems/issues. However such studies have relied on a simple cross-sectional study design. It is therefore hard to draw any conclusions about potential causality and long-term effects at this point, beyond hypothetical speculations. Empirical studies suggest that SNS-addiction is caused by dispositional factors (e.g., personality, needs, self-esteem), although relevant explanatory socio-cultural and behavioral reinforcement factors remain to be empirically explored. No well-documented treatment for SNS-addiction exists, but knowledge gained from Internet addiction treatment approaches might be transferable to SNS-addiction. Overall, the research on this topic is in its infancy, and as such the SNS-addiction construct needs further conceptual and empirical exploration. There is a great demand for studies using careful longitudinal designs and studies which include objective measures of both behavior and health based on broad representative samples.

    2014-07-01

    We present an overview of the VISIR upgrade project. VISIR is the mid-infrared imager and spectrograph at ESO's VLT. The project team is comprised of ESO staff and members of the original VISIR consortium: CEA Saclay and ASTRON. The project plan is based on input from the ESO user community with the goal of enhancing the scientific performance and efficiency of VISIR by a combination of measures: installation of improved hardware, optimization of instrument operations and software support. The cornerstone of the upgrade is the 1k by 1k Si:As AQUARIUS detector array (Raytheon) which has been carefully characterized in ESO's IR detector test facility (modified TIMMI 2 instrument). A prism spectroscopic mode will cover the N-band in a single observation. New scientific capabilities for high resolution and high-contrast imaging will be offered by sub-aperture mask (SAM) and phase-mask coronagraphic (4QPM/AGPM) modes. In order to make optimal use of favourable atmospheric conditions a water vapour monitor has been deployed on Paranal, allowing for real-time decisions and the introduction of a user-defined constraint on water vapour. During the commissioning in 2012 it was found that the on-sky sensitivity of the AQUARIUS detector was significantly below expectations and that VISIR was not ready to go back to science operations. Extensive testing of the detector arrays in the laboratory and on-sky enabled us to diagnose the cause for the shortcoming of the detector as excess low frequency noise (ELFN). It is inherent to the design chosen for this detector and can't be remedied by changing the detector set-up. Since this is a form of correlated noise its impact can be limited by modulating the scene recorded by the detector. We have studied several mitigation options and found that faster chopping using the secondary mirror (M2) of the VLT offers the most promising way forward. Faster M2 chopping has been tested and is scheduled for implementation before the end of 2014

  18. An Overview of Biofield Devices.

    Muehsam, David; Chevalier, Gaétan; Barsotti, Tiffany; Gurfein, Blake T

    2015-11-01

    Advances in biophysics, biology, functional genomics, neuroscience, psychology, psychoneuroimmunology, and other fields suggest the existence of a subtle system of "biofield" interactions that organize biological processes from the subatomic, atomic, molecular, cellular, and organismic to the interpersonal and cosmic levels. Biofield interactions may bring about regulation of biochemical, cellular, and neurological processes through means related to electromagnetism, quantum fields, and perhaps other means of modulating biological activity and information flow. The biofield paradigm, in contrast to a reductionist, chemistry-centered viewpoint, emphasizes the informational content of biological processes; biofield interactions are thought to operate in part via low-energy or "subtle" processes such as weak, nonthermal electromagnetic fields (EMFs) or processes potentially related to consciousness and nonlocality. Biofield interactions may also operate through or be reflected in more well-understood informational processes found in electroencephalographic (EEG) and electrocardiographic (ECG) data. Recent advances have led to the development of a wide variety of therapeutic and diagnostic biofield devices, defined as physical instruments best understood from the viewpoint of a biofield paradigm. Here, we provide a broad overview of biofield devices, with emphasis on those devices for which solid, peer-reviewed evidence exists. A subset of these devices, such as those based upon EEG- and ECG-based heart rate variability, function via mechanisms that are well understood and are widely employed in clinical settings. Other device modalities, such a gas discharge visualization and biophoton emission, appear to operate through incompletely understood mechanisms and have unclear clinical significance. Device modes of operation include EMF-light, EMF-heat, EMF-nonthermal, electrical current, vibration and sound, physical and mechanical, intentionality and nonlocality, gas and

    Full Text Available The aim of this study is to present a contribution on how these policies for child-hood have been carried out in the case of Spain, despite the fact that “to speak of childhood and child education is to place ourselves in a complex context of necessities, interests and demands from children, families and society” (Sánchez, 2008: 76-77. To this end, we use some indicators that reflect the expansion of child-hood policies, especially educational ones, although they differ depending on the age range considered (less than three or between three and six and there is, therefore, a limited provision of educational and social policies of attention and care for children younger than three and their families.

In the first, an overview is given of the development of childcare in Spain, centring on the duality between family and school, and showing how such care for the child population differs according to the age range considered. The second section deals with a number of key elements to be considered concerning the demand for public policies on childcare. Some alternative strategies are then described, given the lack of care policies. Finally, the conclusions occupy the last section.

  20. ULTRATHIN FROZEN SECTIONS

    Bernhard, W.; Leduc, Elizabeth H.

    1967-01-01

    A relatively simple method for obtaining ultrathin, frozen sections for electron microscopy has been developed. Tissues, cultured cells, and bacteria may be employed. They are fixed in 1.25–4% glutaraldehyde for 1–4 hr, are washed overnight in buffer at 3°C, and are embedded in 20% thiolated gelatin or pure gelatin. Before sectioning they are partially dehydrated in 50% glycerol, frozen in liquid nitrogen on a modified tissue holder, and subsequently maintained at -70°C with dry ice. Finally, they are sectioned very rapidly with glass knives on a slightly modified Porter-Blum MT-1 microtome in a commercial deep-freeze maintained at -35°C and are floated in the trough of the knife on a 40% solution of dimethylsulfoxide (DMSO). The sections are picked up in plastic loops and transferred to distilled water at room temperature for thawing and removal of the DMSO, placed on grids coated with Formvar and carbon, air-dried, and stained with phosphotungstic acid, sodium silicotungstate, or a triple stain of osmium tetroxide, uranyl acetate, and lead. Large flat sections are obtained in which ultrastructural preservation is good. They are particularly useful for cytochemical studies. PMID:4167504

  1. Constructing Overview + Detail Dendrogram-Matrix Views

    A dendrogram that visualizes a clustering hierarchy is often integrated with a reorderable matrix for pattern identification. The method is widely used in many research fields including biology, geography, statistics, and data mining. However, most dendrograms do not scale up well, particularly with respect to problems of graphical and cognitive information overload. This research proposes a strategy that links an overview dendrogram and a detail-view dendrogram, each integrated with a re-orderable matrix. The overview displays only a user-controlled, limited number of nodes that represent the “skeleton” of a hierarchy. The detail view displays the sub-tree represented by a selected meta-node in the overview. The research presented here focuses on constructing a concise overview dendrogram and its coordination with a detail view. The proposed method has the following benefits: dramatic alleviation of information overload, enhanced scalability and data abstraction quality on the dendrogram, and the support of data exploration at arbitrary levels of detail. The contribution of the paper includes a new metric to measure the “importance” of nodes in a dendrogram; the method to construct the concise overview dendrogram from the dynamically-identified, important nodes; and measure for evaluating the data abstraction quality for dendrograms. We evaluate and compare the proposed method to some related existing methods, and demonstrating how the proposed method can help users find interesting patterns through a case study on county-level U.S. cervical cancer mortality and demographic data.

  3. Overview of High Power Vacuum Dry RF Load Designs

    2015-08-27

    A specific feature of RF linacs based on the pulsed traveling wave (TW) mode of operation is that only a portion of the RF energy is used for the beam acceleration. The residual RF energy has to be terminated into an RF load. Higher accelerating gradients require higher RF sources and RF loads, which can stably terminate the residual RF power. RF feeders (from the RF source though the accelerating section to the load) are vacuumed to transmit multi-megawatt high power RF. This overview will outline vacuumed RF loads only. A common method to terminate multi-MW RF power is to use circulated water (or other liquid) as an absorbing medium. A solid dielectric interface (a high quality ceramic) is required to separate vacuum and liquid RF absorber mediums. Using such RF load approaches in TW linacs is troubling because there is a fragile ceramic window barrier and a failure could become catastrophic for linac vacuum and RF systems. Traditional loads comprising of a ceramic disk have limited peak and average power handling capability and are therefore not suitable for high gradient TW linacs. This overview will focus on ''vacuum dry'' or ''all-metal'' loads that do not employ any dielectric interface between vacuum and absorber. The first prototype is an original design of RF loads for the Stanford Two-Mile Accelerator.

  9. Nutraceuticals in hypercholesterolaemia: an overview

    Science.gov (United States)

    Santini, Antonello

    2016-01-01

    Growing attention is now being given to the possible preventive/alternative ways to avoid illness onset. Changes in lifestyle and food habits are taking over from the conventional pharmaceutical‐based approach, especially for chronic pathologies. Nutraceuticals have been proposed as key tools for the prevention and cure of some pathological conditions. This is leading research to develop new formulations based on these pharma‐foods addressed in a specific way to prevent and cure health issues, which, in turn, will have an effect on therapy‐related costs sustained by any National Health Organization. According to existing regulations, nutraceuticals cannot be categorized as either food or drugs but, by definition, often inhabit a grey area in between the two, being assimilated into food supplements, notwithstanding the beneficial properties that they can provide for some pathological conditions. A nutraceuticals‐based approach for health management, in particular for some pathological conditions, has resulted in a worldwide growing ‘nutraceutical’ revolution. An outstanding example is the approach to the ‘metabolic syndrome’, which includes overweight, obesity and cardiovascular‐related diseases, causing a sort of cascade of chronic health conditions, which is becoming a norm in modern life. Hypercholesterolaemia is one of these. It represents an example of a pathology that can be linked to both a poor lifestyle and dietary habits. The nutraceutical approach to hypercholesterolaemia is described in the present review as a possible alternative to the conventional drug‐based therapy.

  10. Sectional dentures revisited.

    Karir, Naveen; Hindocha, Vishali; Walmsley, A Damien

    2012-04-01

    Sectional dentures are constructed in separate parts which join together intra-orally to create a single prosthesis. They are used to exploit undercuts around teeth, hard and soft tissues which require more than one path of insertion, and are usually of split pin or locking bolts design. By using two case studies, we aim to illustrate the provision of sectional dentures and to which situations their uses are best suited. A 30-year-old male was referred to the Department of Prosthetics at the Birmingham Dental Hospital for a replacement upper partial cobalt chrome denture of a Kennedy Class IV bounded saddle. The patient had a history of failed upper cobalt chrome removable partial dentures owing to loss of retention and poor stability over the previous 12 months. A 40-year-old female patient was referred by her GDP for restoration of a bounded saddle in the lower right quadrant with a history of intolerance to previous dentures. These two cases demonstrate the successful use of sectional dentures in the aesthetic zone. Although more technically demanding, they lie well within the scope of general practice and offer patients alternative solutions from dental implants and bridgework. These cases highlight the importance of the use of alternative prosthetic techniques which can be simple and achievable for all practitioners. Sectional dentures are a treatment modality for the edentulous space where the presence of one or more undercuts prevents restoration by more conventional techniques. This paper highlights some of the situations in which sectional dentures can be employed and emphasizes their use in general practice.

  13. In-medium Properties of Hadrons - an Overview

    CERN Document Server

    Metag, Volker

    2012-01-01

    An overview is given over recent results on in-medium properties of hadrons, obtained in experiments with photon, proton and deuteron beams at ANKE, CBELSA/TAPS, Crystal Ball, HADES, and BigRIPS. These experiments focus on identifying spectral in-medium modifications of hadrons, frequently discussed in the context of a partial restoration of chiral symmetry at finite nuclear densities. Three experimental approaches are presented: the measurement of the transparency ratio, the meson line shape analysis, and the search for meson-nucleus bound states. Results for $\\omega,\\phi, $ and $ \\eta^\\prime$ mesons indicate a broadening in the nuclear medium. Corresponding inelastic in-medium meson-nucleon cross sections have been extracted. Evidence for an in-medium mass shift has not been reported. Further information on the meson-nucleus interaction is derived from a spectroscopy of meson-nucleus bound states. A critical comparison of the results with theoretical predictions is presented.

    The ATLAS Collaboration is engaged in precision measurement of fundamental Standard Model parameters, such as the W boson mass, the weak-mixing angle or the strong coupling constant. In addition, the production cross-sections of a large variety of final states involving high energetic jets, photons as well as single and multi vector bosons are measured multi differentially at several center of mass energies. This allows to test perturbative QCD calculations to highest precision. In addition, these measurements allow also to test models beyond the SM, e.g. those leading to anomalous gauge couplings. In this talk, we give a broad overview of the Standard Model measurement campaign of the ATLAS collaboration, where selected topics will be discussed in more detail.

  14. Ionic liquids--an overview.

    Science.gov (United States)

    Jenkins, Harry Donald Brooke

    2011-01-01

    A virtually unprecedented exponential burst of activity resulted following the publication, in 1998, of an article by Michael Freeman (Freemantle, M. Chemical & Engineering News, 1998, March 30, 32), which speculated on the role and contribution that ionic liquids (ILs) might make in the future on the development of clean technology. Up until that time only a handful of researchers were routinely engaged in the study of ILs but frenzied activity followed that continues until the present day. Scientists from all disciplines related to Chemistry have now embarked on studies, including theoreticians who are immersed in the aim of improving the "designer role" so that they can tailor ILs to deliver specified properties. This article, whilst not in any sense attempting to be exhaustive, highlights the main features which characterise ILs, presenting these in a form readily assimilated by newcomers to this area of research. An extensive glossary is featured in this article as well as a chronological list which charts the major areas of development. What follows consists of a number of sections briefly describing the role of lLs as solvents, hypergolic fuels, their use in some electrochemical devices such as solar cells and lithium batteries and their use in polymerisation reactions, followed by a concise summary of some of the other roles that they are capable of playing. The role of empirical, volume-based thermodynamics procedures, as well as large scale computational studies on ILs is also highlighted. These developments which are described are remarkable in that they have been achieved in less than a decade and a half although knowledge of these materials has existed for much longer.

  15. A brief overview of kurtosis

    Energy Technology Data Exchange (ETDEWEB)

    Booker, J.M.; Ticknor, L.O.

    1998-12-01

    The standardized fourth central moment (standardized according to the variance) is often regarded as the definition of kurtosis and has a history of usage for testing normality and multivariate normality. Its relationship to other standard central moments is also documented. However, the poor performance of the standardized central moments skewness and kurtosis as discriminators for normality has led to seeking alternative statistics and definitions to capture distribution shape characteristics. Included in these kurtosis statistics are quantile based statistics and L-kurtosis, which comes from L-moments. Balanda and MacGillivray provide a more general definition if kurtosis as the location-free and scale-free movement of the probability mass from the shoulders of the distribution to its center and tails. Different scaling techniques and positionings of the shoulders result in different forms for kurtosis related to peakedness and tail weight. Often counter to popular view, kurtosis is both tailedness and peakedness, simultaneously. It is related to skewness, spread, tail weight, quantiles, and influence functions. Various kurtosis statistics have been developed as indicators for bimodality, tail weight, peakedness and normality. These are also useful for distribution comparisons, such as goodness-of-fit, distribution crossings and distribution orderings. Kurtosis measures are related to Box-Cox transformations and Kullback-Leibler information. In the following sections, the authors examining various kurtosis measures, and illustrate their performance using a case study where understanding distribution shape is important for comparing simulated and mixtures of distributions. The concluding remarks include drawing attention to areas for further study.

  20. Overview of Deployed EDS Technologies

    Energy Technology Data Exchange (ETDEWEB)

    Martz, H E; Crawford, C

    2009-09-24

    The term explosive detection system (EDS) is used by the TSA to describe equipment that is certified to detect explosives in checked bags. The EDS, as certified, by the TSL must consist of device for interrogating a bag and an automated detection algorithm (ATD) for evaluating the results of the interrogation. We only consider CT as the interrogation device in this report. A schematic drawing of a CT-based EDS is shown in Figure 2. The output of the ATD is the binary decision of alarm or non-alarm. Alarms may true- or false-positives. Non-alarms may be true- or false-negatives. False positives are also denoted false alarms. The true detection means that the ATD reports an alarm when a threat is present in the scanned bag. The probability of detecting a threat given that a threat is present is denoted the probability of detection (PD). The probability of false alarm (PFA) is the case when an alarm is reported when a threat is not present in a bag. Certification in this context means passing tests for PD and PFA at the TSL. The results of the EDS include CT cross-sectional images of the bag and specifics about the alarmed objects generated by ATD. These results are presented on a display so that a person may override the decision of ATD and declare the alarm to be a non-alarm. This process is denoted clearing. Bags that are not cleared by the person are sent to a secondary inspection process. Here the bags may be opened or assessed with explosive trace detection (ETD) in order to clear the bags. Bags that are not cleared at this point are evaluated by an ordinance disposal team. The CT scanner along with ATD is denoted Level 1 screening. The process of clearing on a display is denoted Level 2 screening. Secondary inspection is denoted Level 3 screening. Vendors of the deployed EDSs supply the TSA with equipment for all three levels. Therefore, the term EDS may include the equipment provided for Levels 1, 2 and 3. A schematic diagram of an EDS and the levels of

  1. Ecology through time, an overview.

    2006-01-01

    This brief review is an attempt to condense the major events in the history of Ecology into short 10 sections. In little more than two generations, a new science has emerged and developed into a fundamental part of our lives, spurred on by increasing interest in "natural systems" and concerns over the environmental changes we are witnessing. Ecology, rather neglected until the early decades of last century, flourished and established itself as mature science during the mid-1900s, producing many theories, models, hypothesis and trends of thought. Ecology deals with interacting natural systems and eclectically applies tools drawn from several different sciences (Biology, Mathematics, Statistics, Chemistry, Geology, Physics and so on). The beauty of the subject and its multidisciplinary approach makes Ecology extremely intriguing for researchers. One of the main goals of Ecology is to forecast population, community and ecosystem trends over time. Ecological systems are complex: they are composed of such a large number of different, interacting components that their overall behavior can only be understood in terms of emerging properties. Therefore, some interactions and effects are difficult to predict. However, some insights into population and community trends can be inferred from exhaustive data sets and sufficiently long-term, time-series data and dynamic models. Unfortunately, due to the limited funding of environmental data collection, only a few exhaustive, long-term samplings have been carried out, and systematic record keeping for the purposes of ecological research has only recently become widespread. However, it is still possible to garner some insights from historical reports (proxies), which clearly show how the population structures of most of today's communities have been affected by human activities. This short review is based on a talk given at Arcidosso (Grosseto, Italy) during the September, 2005 workshop: "Scientific research and society during the

  2. Radar cross section

    This is the second edition of the first and foremost book on this subject for self-study, training, and course work. Radar cross section (RCS) is a comparison of two radar signal strengths. One is the strength of the radar beam sweeping over a target, the other is the strength of the reflected echo sensed by the receiver. This book shows how the RCS ?gauge? can be predicted for theoretical objects and how it can be measured for real targets. Predicting RCS is not easy, even for simple objects like spheres or cylinders, but this book explains the two ?exact? forms of theory so well that even a

  5. Batteries: Overview of Battery Cathodes

    Energy Technology Data Exchange (ETDEWEB)

    Doeff, Marca M

    2010-07-12

    hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs); a market predicted to be potentially ten times greater than that of consumer electronics. In fact, only Liion batteries can meet the requirements for PHEVs as set by the U.S. Advanced Battery Consortium (USABC), although they still fall slightly short of EV goals. In the case of Li-ion batteries, the trade-off between power and energy shown in Figure 1 is a function both of device design and the electrode materials that are used. Thus, a high power battery (e.g., one intended for an HEV) will not necessarily contain the same electrode materials as one designed for high energy (i.e., for an EV). As is shown in Figure 1, power translates into acceleration, and energy into range, or miles traveled, for vehicular uses. Furthermore, performance, cost, and abuse-tolerance requirements for traction batteries differ considerably from those for consumer electronics batteries. Vehicular applications are particularly sensitive to cost; currently, Li-ion batteries are priced at about $1000/kWh, whereas the USABC goal is $150/kWh. The three most expensive components of a Li-ion battery, no matter what the configuration, are the cathode, the separator, and the electrolyte. Reduction of cost has been one of the primary driving forces for the investigation of new cathode materials to replace expensive LiCoO{sub 2}, particularly for vehicular applications.

    hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and electric vehicles (EVs); a market predicted to be potentially ten times greater than that of consumer electronics. In fact, only Liion batteries can meet the requirements for PHEVs as set by the U.S. Advanced Battery Consortium (USABC), although they still fall slightly short of EV goals. In the case of Li-ion batteries, the trade-off between power and energy shown in Figure 1 is a function both of device design and the electrode materials that are used. Thus, a high power battery (e.g., one intended for an HEV) will not necessarily contain the same electrode materials as one designed for high energy (i.e., for an EV). As is shown in Figure 1, power translates into acceleration, and energy into range, or miles traveled, for vehicular uses. Furthermore, performance, cost, and abuse-tolerance requirements for traction batteries differ considerably from those for consumer electronics batteries. Vehicular applications are particularly sensitive to cost; currently, Li-ion batteries are priced at about $1000/kWh, whereas the USABC goal is $150/kWh. The three most expensive components of a Li-ion battery, no matter what the configuration, are the cathode, the separator, and the electrolyte. Reduction of cost has been one of the primary driving forces for the investigation of new cathode materials to replace expensive LiCoO{sub 2}, particularly for vehicular applications. Another extremely important factor is safety under abuse conditions such as overcharge. This is particularly relevant for the large battery packs intended for vehicular uses, which are designed with multiple cells wired in series arrays. Premature failure of one cell in a string may cause others to go into overcharge during passage of current. These considerations have led to the development of several different types of cathode materials, as will be covered in the next section. Because there is not yet one ideal material that can

    Pheochromocytoma is a catecholamine-producing tumor. There are a very few reported cases of clinical pheochromocytoma. Here, we report a 27-year-old woman para 1 live 1 with chief complaint of headache, confusion, nausea, and vomiting 2 days after cesarean section. She was anxious and had palpitation. On physical examination, fever, tachycardia, tachypnea, high blood pressure, and right thyroid nodule were found. She was managed as pregnancy-induced hypertension at first. In laboratory data, epinephrine, norepinephrine, metanephrine, normetanephrine, and vanillylmandelic acid were increased in 24 h urine collection. An adrenal mass was detected in abdominal computed tomography. Regarding clinical and paraclinical findings, pheochromocytoma was diagnosed. The patient received medical treatment, but it was not effective; hence, she underwent adrenalectomy. PMID:27076898

  18. Pion photoproduction cross section at large momentum transfer

    Energy Technology Data Exchange (ETDEWEB)

    Sjoegren, Johan [Univ. of Glasgow, Scotland, United Kingdom

    2015-02-27

    The Real Compton Scattering experiment was performed in Hall A at the Thomas Jefferson National Accelerator Facility. It was designed to measure, for Compton scattering and π0-photoproduction, the differential cross section over a range of kinematic points and the polarisation transfer to the proton at a single kinematic point. The full range of the experiment in Mandelstam variables t and s was 1.6-6.46 GeV2 and 4.82-10.92 GeV2 respectively with beam energies of 2-6 GeV. The motivation for the experiment is to test the cross section and polarisation transfer predictions of perturbative QCD versus that of predictions from Generalised Parton Distribution models. This thesis will give an overview of the pertinent theory, experimental setup in Hall A and the extracting of the π0-photoproduction cross section.

  11. Overview of MicroRNA Biology

    OpenAIRE

    2015-01-01

    In considering an overview of microRNA biology, it is useful to consider microRNAs as a part of cellular communication. At the simplest level, microRNAs act to decrease the expression of mRNAs that contain stretches of sequence complementary to the microRNA. This function can be likened to the function of endogenous or synthetic short interfering RNA (siRNA). However, microRNA function is more complicated and nuanced than this ‘on-off’ model would suggest. Further, many microRNA targets are t...

    2009-01-01

    Plants are complex structures, changing their shapes in response to environmental factors such as sunlight, water and neighboring plants. However, some mathematical rules can be found in their growth patterns, one of which is the golden section. The golden section can be observed in branching systems, phyllotaxis, flowers and seeds, and often the spiral arrangement of plant organs. In this study, tree, flower and fruit models have been generated by using the corresponding golden section characteristics, resulting in more natural patterns. Furthermore, the golden section can be found in the bifurcate angles of trees and lobed leaves, extending the golden section theory.

    Le Dû, P

    1999-01-01

    Summary form only given. This paper gives an overview of the event selection for ATLAS, prior to event building, with the emphasis on the level-2 trigger. (A further stage of selection after event building is described in a separate presentation-ref Event Filter overview.) The level-1 trigger based on custom hardware processes coarse-grain data from the calorimeters and dedicated muon trigger chambers to give a selection of approximately one interaction in 10**5 (one bunch crossing in 10**3). The level-2 trigger processes selected fine-grain data from all detectors to give a further selection of one in 10**2. Studies of the estimated physics rates and detector data volumes have led to a sequential level-2 selection strategy guided by Region of Interest pointers from level-1. The influence of low luminosity (b physics) and high luminosity (high pT) running on the strategy and the architectural options is discussed. The models and testbeds used in developing and testing the strategy are described. Finally the t...

    2012-01-01

    In this paper, we present an overview of ASTROD-GW (ASTROD [Astrodynamical Space Test of Relativity using Optical Devices] optimized for Gravitational Wave [GW] detection) mission concept and its studies. ASTROD-GW is an optimization of ASTROD which focuses on low frequency gravitational wave detection. The detection sensitivity is shifted by a factor of 260 (52) towards longer wavelengths compared with that of NGO/eLISA (LISA). The mission consists of three spacecraft, each of which orbits near one of the Sun-Earth Lagrange points (L3, L4 and L5), such that the array forms an almost equilateral triangle. The 3 spacecraft range interferometrically with one another with an arm length of about 260 million kilometers. The orbits have been optimized resulting in arm length changes of less than 0.00015 AU or, fractionally, less than 10^(-4) in twenty years, and relative Doppler velocities of the three spacecraft of less than 3 m/s. In this paper, we present an overview of the mission covering: the scientific aims,...

  16. OVERVIEW OF BERYLLIUM SAMPLING AND ANALYSIS

    Energy Technology Data Exchange (ETDEWEB)

    Brisson, M

    2009-04-01

    Because of its unique properties as a lightweight metal with high tensile strength, beryllium is widely used in applications including cell phones, golf clubs, aerospace, and nuclear weapons. Beryllium is also encountered in industries such as aluminium manufacturing, and in environmental remediation projects. Workplace exposure to beryllium particulates is a growing concern, as exposure to minute quantities of anthropogenic forms of beryllium may lead to sensitization and to chronic beryllium disease, which can be fatal and for which no cure is currently known. Furthermore, there is no known exposure-response relationship with which to establish a 'safe' maximum level of beryllium exposure. As a result, the current trend is toward ever lower occupational exposure limits, which in turn make exposure assessment, both in terms of sampling and analysis, more challenging. The problems are exacerbated by difficulties in sample preparation for refractory forms of beryllium, such as beryllium oxide, and by indications that some beryllium forms may be more toxic than others. This chapter provides an overview of sources and uses of beryllium, health risks, and occupational exposure limits. It also provides a general overview of sampling, analysis, and data evaluation issues that will be explored in greater depth in the remaining chapters. The goal of this book is to provide a comprehensive resource to aid personnel in a wide variety of disciplines in selecting sampling and analysis methods that will facilitate informed decision-making in workplace and environmental settings.

    2016-01-01

    Aim: At the annual meeting of German dentists in Frankfurt am Main in 2013, the Working Group for the Advancement of Dental Education (AKWLZ) initiated an interdisciplinary working group to address assessments in dental education. This paper presents an overview of the current work being done by this working group, some of whose members are also actively involved in the German Association for Medical Education's (GMA) working group for dental education. The aim is to present a summary of the current state of research on this topic for all those who participate in the design, administration and evaluation of university-specific assessments in dentistry. Method: Based on systematic literature research, the testing scenarios listed in the National Competency-based Catalogue of Learning Objectives (NKLZ) have been compiled and presented in tables according to assessment value. Results: Different assessment scenarios are described briefly in table form addressing validity (V), reliability (R), acceptance (A), cost (C), feasibility (F), and the influence on teaching and learning (EI) as presented in the current literature. Infoboxes were deliberately chosen to allow readers quick access to the information and to facilitate comparisons between the various assessment formats. Following each description is a list summarizing the uses in dental and medical education. Conclusion: This overview provides a summary of competency-based testing formats. It is meant to have a formative effect on dental and medical schools and provide support for developing workplace-based strategies in dental education for learning, teaching and testing in the future.

  18. Biological effects of electric fields: an overview

    Energy Technology Data Exchange (ETDEWEB)

    Anderson, L.E.; Phillips, R.D.

    1983-11-01

    An overview of the literature suggests tha electric-field exposure is an environmental agent/influence of relatively low potential toxicity to biological systems. Generally, many of the biological effects which have been reported are quite subtle and differences between exposed and unexposed subjects may be masked by normal biological variations. However, several recent reports indicate possibly more serious consequences from chronic exposure, emphasizing the need for more research in epidemiology and laboratory experiments. This paper presents a cursory overview of investigations on the biological consequences of exposure to ELF electromagnetic fields. Three important topics are discussed, including: 1) the general methodology of exposure experiments, including those elements which are critical for definitive studies in biological systems; 2) a brief discussion of epidemiological and clinical studies conducted to date; and 3) a somewhat more extensive examination of animal experiments representing major areas of investigation (behavior, biological rhythms, nervous and endocrine systems, bone growth and repair, cardiovascular system and blood chemistry, immunology, reproduction, growth and development mortality and pathology, cellular and membrane studies, and mutagenesis). A discussion of current concepts, possible mechanisms and future directions of research is presented. 110 references.

  19. Pairwise Trajectory Management (PTM): Concept Overview

    Jones, Kenneth M.; Graff, Thomas J.; Chartrand, Ryan C.; Carreno, Victor; Kibler, Jennifer L.

    2017-01-01

    Pairwise Trajectory Management (PTM) is an Interval Management (IM) concept that utilizes airborne and ground-based capabilities to enable the implementation of airborne pairwise spacing capabilities in oceanic regions. The goal of PTM is to use airborne surveillance and tools to manage an "at or greater than" inter-aircraft spacing. Due to the precision of Automatic Dependent Surveillance-Broadcast (ADS-B) information and the use of airborne spacing guidance, the PTM minimum spacing distance will be less than distances a controller can support with current automation systems that support oceanic operations. Ground tools assist the controller in evaluating the traffic picture and determining appropriate PTM clearances to be issued. Avionics systems provide guidance information that allows the flight crew to conform to the PTM clearance issued by the controller. The combination of a reduced minimum distance and airborne spacing management will increase the capacity and efficiency of aircraft operations at a given altitude or volume of airspace. This paper provides an overview of the proposed application, description of a few key scenarios, high level discussion of expected air and ground equipment and procedure changes, overview of a potential flight crew human-machine interface that would support PTM operations and some initial PTM benefits results.

    1978-01-01

    This report is an excerpt from the interim report of a study on the effects of risk on prices and quantities of energy supply. It is an overview of economic theory of uncertainty and summarizes much of the economics literature of the past 10 to 15 years on risk and uncertainty. After a brief introductory section, the second section reviews the economic principles of risk bearing, which include such topics as the measurement of risk, the institutional structures by which risks are shared in the economy, activities that reduce risk, and market mechanisms that provide incentives for risk reduction. The third section examines the effects of uncertainty on the price and quantity decisions of firms. It reviews the sources of risk, the characteristics of risk, the producer's attitudes toward risk, and the effects of market structure and regulation on decision making.

    Tanaka, Hide-Kazu

    2008-04-01

    The precise measurement of neutrino-nucleus cross-sections in the few GeV energy range is an essential ingredient in the interpretation of neutrino oscillation experiments. For the measurement of the cross-sections, a new experiment, SciBooNE, has been proposed and approved at Fermilab. From June 2007, SciBooNE has started operation and data taking. The experiment is carried out by installing the K2K SciBar detector in the FNAL Booster Neutrino Beamline. The marriage of a high rate, low energy neutrino beam and the fine granularity of SciBar detector is unique for precise measurements of neutrino cross sections since both the beamline and detectors have been built and operated successfully. We will present an overview of the SciBooNE physics program with emphasis on unique elements of the detector systems that allow for identification and measurement of several types of neutrino interactions.

  2. NIFFTE Time Projection Chamber for Fission Cross Section Measurements

    Castillo, Ryan; Neutron Induced Fission Fragment Tracking Experiment Collaboration

    2011-10-01

    In order to design safer and more efficient Generation IV nuclear reactors, more accurate knowledge of fission cross sections is needed. The goal of the Time Projection Chamber (TPC) used by the Neutron Induced Fission Fragment Tracking Experiment (NIFFTE) collaboration is to measure the cross sections of several fissile materials to within 1% uncertainty. The ability of the TPC to produce 3D ``pictures'' of charged particle trajectories will eliminate unwanted alpha particles in the data. Another important source of error is the normalization of data the U-235 standard. NIFFTE will use the H(n,n)H reaction instead, which is known to better than 0.2%. The run control and monitoring system will eventually allow for nearly complete automation and off-site monitoring of the experiment. This presentation will cover the need for precision measurements and an overview of the experiment. This work was supported by the U.S. Department of Energy Division of Energy Research.

    The Savannah River Site (SRS) was bulk to produce plutonium and tritium for national defense. As a result of site operations, routine and accidental releases of radionuclides have occurred. The effects these releases have on the k>cal population and environment are of concern to the Department of Energy (DOE) and SRS personnel. Each year, approximately 40,000 environmental samples are collected. The quality of the samples, analytical methods and results obtained are important to site personnel. The Environmental Monitoring Computer Automation Project (EMCAP) was developed to better manage scheduling, log-in, tracking, analytical results, and report generation. EMCAP can be viewed as a custom Laboratory Information Management System (LIMS) with the ability to schedule samples, generate reports, and query data. The purpose of this paper is to give an overview of the SRS environmental monitoring program, describe the development of EMCAP software and hardware, discuss the different software modules, show how EMCAP improved the Environmental Monitoring Section program, and examine the future of EMCAP at SRS.

    Abstract for Manganese 2016A historical overview of the development of manganese (Mn) pharmacokinetic data under Section 211(b) of the Clean Air Act (CAA)William K BoyesBackground. In the 1990’s, the use of methylcyclopentadienyl manganese tricarbonyl (MMT) as an octane-enhancing gasoline fuel additive led to concerns for potential public health consequences from exposure to Mn combustion products in automotive exhaust. Methods: After a series of regulatory / legal actions and negotiations, the EPA issued under CAA 211(b) an Alternative Tier 2 Test Rule that required development of scientific information intended to help resolve uncertainties in exposure or health risk estimates associated with MMT use. Among the uncertainties identified were: the chemical forms of Mn emitted in automotive exhaust; the relative toxicity of different Mn species; the potential for sensitive subpopulations including females, the young and elderly; differences in sensitivity between test species and humans; differences between inhalation and oral exposures; and the influence of dose rate and exposure duration on tissue accumulation of Mn. It was determined that development of specific sets of pharmacokinetic information and models regarding Mn could help resolve much of the uncertainties identified. Results. The results of the test program included development of several unique Mn PK datasets, and a series of increasingly sophisticated Mn physiologically-based pharmacokinetic

    The Singapore Mental Health Study (SMHS) is a population-based, cross-sectional, epidemiological study on the Singapore multi-ethnic adult population. This article provides an overview of the research design and methods used which took into consideration the unique characteristics of the country and its multi-ethnic population. A face-to-face household survey of Singapore residents aged 18 years and above was undertaken from 2009 to 2010. The nationally representative probability sample was derived using a disproportionate stratified sampling method. In order to increase precision for subgroup estimations the design was stratified with over-sampling of Malays, Indians and those aged 65 years and above. Respondents were assessed using the English, Chinese (computerized) and Malay (paper and pencil based) version of the Composite International Diagnostic Interview (CIDI) 3.0 to establish lifetime and 12-month prevalence of mental disorders, the current use of mental health services (both Western and traditional services), the treatment gaps and loss of role functioning.

    Ectopic pregnancies account for 1.5% to 2% of all pregnancy in the United States. Of these, approximately 10% implant in nontubal locations, including the abdominal cavity, cervix, ovary, interstitial portion of the fallopian tube, broad ligament, the uterine cornua, or within a cesarean section scar. Because these pregnancies tend to present later than typical tubal pregnancies, they have been associated with greater maternal morbidity and mortality. Advances in ultrasound technology have allowed for earlier diagnosis of nontubal ectopic pregnancies, which in turn has led to the development of novel minimally invasive techniques to manage them. One of these methods involves the local injection of 1 of several agents directly into the ectopic pregnancy. In this article we provide a guide to this technique of local injection, including an overview of the potential agents that can be used, and review the diagnostic and specific ultrasound criteria, other possible treatment options, and overall outcomes for nontubal ectopic pregnancies.

    2014-12-01

    Full Text Available Electrokinetic decontamination and extraction have been proven to be one of the most viable, cost effective and emerging techniques in removing contaminants, especially heavy metals from soils for about last five decades. Basic concepts and an overview of the electrokinetic extraction processes and their potential applications in geotechnical and geoenvironmental engineering have been reviewed based on the literature and presented in this paper. Primarily, theoretical and laboratory experimental studies related to electroreclamation of soils are summarised in brief with basic concepts of electrokinetic processes. The paper has been divided into different sections that include history of electrokinetics, background and concepts, modelling, parameter effects, instrumentation, contaminant extraction, field applications, and summary and recommendation. Based on the review it is obvious that the field application of electrokinetic technology to remediate heavy metal contaminated soils /sediments is very limited and site specific. Additional laboratory studies and more pilot- and full-scale information from field applications are critical to the further understanding of the technology and to customize the process in different field conditions.

    Carbonaceous chondrite meteorites have long posed a challenge for thin section makers. The variability in sample hardness among the different types, and sometimes within individual sections, creates the need for an adaptable approach at each step of the thin section making process. This poster will share some of the procedural adjustments that have proven to be successful at the NASA JSC Meteorite Thin Section Laboratory. These adjustments are modifications of preparation methods that have been in use for decades and therefore do not require investment in new technology or materials.

    Duncan, J.P.

    1994-03-01

    This report is a result of the Hanford Environmental Dose Reconstruction (HEDR) Project. The goal of the HEDR Project is to estimate the radiation dose that individuals could have received from emissions since 1944 at the Hanford Site near Richland, Washington. Members of the HEDR Project`s Environmental Monitoring Data Task have developed databases of historical environmental measurements of such emissions. The HEDR Project is conducted by Battelle, Pacific Northwest Laboratories. This report is the third in a series that documents the information available on measurements of iodine-131 concentrations in vegetation. The first two reports provide the data for 1945--1951. This report provides an overview of the historical documents, which contain vegetation data for 1952--1983. The overview is organized according to the documents available for any given year. Each section, covering one year, contains a discussion of the media sampled, the sampling locations, significant events if there were any, emission quantities, constituents measured, and a list of the documents with complete reference information. Because the emissions which affected vegetation were significantly less after 1951, the vegetation monitoring data after that date have not been used in the HEDR Project. However, access to these data may be of interest to the public. This overview is, therefore, being published.

    Directory of Open Access Journals (Sweden)

    Zeqir Vesela

    2015-12-01

    Full Text Available This paper presents an overview of progress in the area of nature conservation in the last decade in Kosovo. Two very important laws were promulgated in 2012 about two national parks: Bjeshket e Nemuna and Sharri National park. With this expansion, the protected area network that in 2003 was about 4.36 % of the territory was increased to 10.9%, reaching a satisfactory degree of protected areas and increasing the number of protected areas in a total of 116. While in terms of conservation of protected areas a significant progress has been achieved, stagnation is seen in the conservation of rare and threatened species of flora and fauna. Although envisaged by legislation, the Red List of Kosovo of rare and threatened species has not been adopted yet. Also, there is a small progress in the implementation of practical conservation and management measures contained in the legislation.

  11. Heavy flavour hadron spectroscopy: An overview

    Indian Academy of Sciences (India)

    P C Vinodkumar

    2014-11-01

    A comprehensive overview and some of the theoretical attempts towards understanding heavy flavour hadron spectroscopy are presented. Apart from the conventional quark structure (quark, antiquarks structure for the mesons and three-quarks structure of baryons) of hadrons, multiquark hadrons the hadron molecular states etc., also will be reviewed. Various issues and challenges in understanding the physics and dynamics of the quarks at the hadronic dimensions are highlighted. Looking into the present and future experimental prospects at different heavy flavour laboratories like BES-III, CLEO-c, BaBar, Belle, LHC etc., the scope for theoretical extensions of the present knowledge of heavy flavour physics would be very demanding. In this context, many relevant contributions from the forthcoming PANDA Facility are expected. Scopes and outlook of the hadron physics at the heavy flavour sector in view of the future experimental facilities are highlighted.

The Radio Experiment (REX) is a component of the New Horizons telecommunications system that provides both occultation and radiometry capabilities. ...

  13. [Autism and Asperger syndrome: an overview].

    Science.gov (United States)

    Klin, Ami

    2006-05-01

    Autism and Asperger syndrome are diagnostic entities in a family of neurodevelopmental disorders disrupting fundamental processes of socialization, communication and learning, collectively known as pervasive developmental disorders. This group of conditions is among the most common developmental disorders, affecting 1 in every 200 or so individuals. They are also the most strongly genetically related among developmental disorders, with recurrence risks within sibships of the order of 2 to 15% if a broader definition of affectedness is adopted. Their early onset, symptom profile, and chronicity implicate fundamental biological mechanisms involved in social adaptation. Advances in their understanding are leading to a new social neuroscience perspective of normative socialization processes and specific disruptions thereof. These processes may lead to the emergence of the highly heterogeneous phenotypes associated with autism, the paradigmatic pervasive developmental disorder, and its variants. This overview focuses on the history, nosology, and the clinical and associated features of the two most well-known pervasive developmental disorders - autism and Asperger syndrome.

  18. Mobile multimedia understanding applications: an overview

    Science.gov (United States)

    Lin, Xiaofan

    2011-03-01

    In recent years, mobile devices are quickly reaching almost every corner of our daily life in a variety of forms: personal media players, smart phones, netbooks, and tablets. Besides the more powerful, smaller, and more versatile hardware, another driving force is the vast number of software applications ("apps") on those mobile devices. A number of mobile apps employ intelligent multimedia understanding (MU) technologies. This paper gives an overview of such apps. The focus is not on the underlying MU techniques, which are already covered by a huge amount of literature. Instead, it attempts to shed some light on the junction of mobile apps and MU. For this purpose, it addresses a number of important aspects: unique requirements and characteristics of MU-related apps, values brought in by MU, typical MU technologies, various system architectures, available development tools, and related standards.

  19. Overview of the purification of recombinant proteins.

    Science.gov (United States)

    Wingfield, Paul T

    2015-04-01

    When the first version of this unit was written in 1995, protein purification of recombinant proteins was based on a variety of standard chromatographic methods and approaches, many of which were described and mentioned throughout Current Protocols in Protein Science. In the interim, there has been a shift toward an almost universal usage of the affinity or fusion tag. This may not be the case for biotechnology manufacture where affinity tags can complicate producing proteins under regulatory conditions. Regardless of the protein expression system, questions are asked as to which and how many affinity tags to use, where to attach them in the protein, and whether to engineer a self-cleavage system or simply leave them on. We will briefly address some of these issues. Also, although this overview focuses on E.coli, protein expression and purification, other commonly used expression systems are mentioned and, apart from cell-breakage methods, protein purification methods and strategies are essentially the same.

  1. Superconducting Radio Frequency Technology: An Overview

    Energy Technology Data Exchange (ETDEWEB)

    Peter Kneisel

    2003-06-01

    Superconducting RF cavities are becoming more often the choice for larger scale particle accelerator projects such as linear colliders, energy recovery linacs, free electron lasers or storage rings. Among the many advantages compared to normal conducting copper structures, the superconducting devices dissipate less rf power, permit higher accelerating gradients in CW operation and provide better quality particle beams. In most cases these accelerating cavities are fabricated from high purity bulk niobium, which has superior superconducting properties such as critical temperature and critical magnetic field when compared to other superconducting materials. Research during the last decade has shown, that the metallurgical properties--purity, grain structure, mechanical properties and oxidation behavior--have significant influence on the performance of these accelerating devices. This contribution attempts to give a short overview of the superconducting RF technology with emphasis on the importance of the material properties of the high purity niobium.

  2. Optomechatronics for Biomedical Optical Imaging: An Overview

    Directory of Open Access Journals (Sweden)

    Cho Hyungsuck

    2015-01-01

    Full Text Available The use of optomechatronic technology, particularly in biomedical optical imaging, is becoming pronounced and ever increasing due to its synergistic effect of the integration of optics and mechatronics. The background of this trend is that the biomedical optical imaging for example in-vivo imaging related to retraction of tissues, diagnosis, and surgical operations have a variety of challenges due to complexity in internal structure and properties of biological body and the resulting optical phenomena. This paper addresses the technical issues related to tissue imaging, visualization of interior surfaces of organs, laparoscopic and endoscopic imaging and imaging of neuronal activities and structures. Within such problem domains the paper overviews the states of the art technology focused on how optical components are fused together with those of mechatronics to create the functionalities required for the imaging systems. Future perspective of the optical imaging in biomedical field is presented in short.

  3. Overview of Olestra: A New Fat Substitute

    Directory of Open Access Journals (Sweden)

    Richard Hunt

    1998-01-01

    Full Text Available Olestra is a mixture of hexa-, hepta- and octa-esters formed from the reaction of sucrase and long chain fatty acids isolated from edible oils. Olestra has properties similar to those of traditional triglycerides but is not hydrolyzed by pancreatic lipases and, therefore, serves as a noncaloric replacement for fats in the diet. The safety of olestra has been established in over 100 studies in seven different species of animals, with confirmatory safety data coming from approximately 75 human studies; consumption of olestra at levels typical for savoury snacks does not result in reports of gastrointestinal problems in humans. This is consistent with the results of studies of the physiological and morphological effects of olestra in animals and in humans. It is anticipated that olestra will be available in Canada in the near future. Patients will soon be asking their physicians about its use. This article provides an overview of olestra.

    We present an overview of the Project 8 experiment, a concept for the next-generation direct neutrino mass measurement after KATRIN, with a sensitivity goal to cover the range of neutrino masses allowed by the inverted mass hierarchy. Project 8 is a tritium endpoint experiment based on Cyclotron Radiation Emission Spectroscopy (CRES) of beta decay electrons from an atomic tritium source. We demonstrate how this combination can offer advantages in both statistical and systematic uncertainties compared to existing technologies. We then present our staged approach to develop the technology for the final experiment, including a discussion of the demanding specifications for an atomic tritium source. This work is supported by the DOE Office of Science Early Career Research Program, and the Laboratory Directed Research and Development Program at Pacific Northwest National Laboratory, a multiprogram national laboratory operated by Battelle for the U.S.

  6. Overview of HPM Effects in Electronics

    Energy Technology Data Exchange (ETDEWEB)

    Holloway, Michael A. [Los Alamos National Laboratory

    2012-06-04

    The following presentation contains an overview of HPM effects in modern electronics. HPM effects can be categorized into two basic level of effects, which are damaging and non-damaging. Damaging effects include junction breakdowns, dielectric breakdowns, and latch-up. These types of effects render a system inoperable until repaired. With non-damaging effects, HPM signals couple to into system components generating circuit responses that can overwhelm normal operation. Non-damaging effects can temporarily render a system inoperable or cause a system to lock and require a restart. Since modern systems are so complex, fundamental mechanisms of upset in circuit primitives are studied. All topics covered and all figured contained within are found in open literature. All data plots presented were obtained from experimental measurements conducted at the University of Maryland College Park and are also found in the open literature.

    Carrion-Castillo, Amaia; Franke, Barbara; Fisher, Simon E

    2013-11-01

    Dyslexia is a highly heritable learning disorder with a complex underlying genetic architecture. Over the past decade, researchers have pinpointed a number of candidate genes that may contribute to dyslexia susceptibility. Here, we provide an overview of the state of the art, describing how studies have moved from mapping potential risk loci, through identification of associated gene variants, to characterization of gene function in cellular and animal model systems. Work thus far has highlighted some intriguing mechanistic pathways, such as neuronal migration, axon guidance, and ciliary biology, but it is clear that we still have much to learn about the molecular networks that are involved. We end the review by highlighting the past, present, and future contributions of the Dutch Dyslexia Programme to studies of genetic factors. In particular, we emphasize the importance of relating genetic information to intermediate neurobiological measures, as well as the value of incorporating longitudinal and developmental data into molecular designs.

    Bartolo, Angela; Ham, Heidi Stieglitz

    2016-08-01

    Since the first studies on limb apraxia carried out by Hugo Liepmann more than a century ago, research interests focused on the way humans process manual gestures by assessing gesture production after patients suffered neurologic deficits. Recent reviews centered their attention on deficits in gesture imitation or processing object-related gestures, namely pantomimes and transitive gestures, thereby neglecting communicative/intransitive gestures. This review will attempt to reconcile limb apraxia in its entirety. To this end, the existing cognitive models of praxis processing that have been designed to account for the complexity of this disorder will be taken into account, with an attempt to integrate in these models the latest findings in the studies of limb apraxia, in particular on meaningful gestures. Finally, this overview questions the very nature of limb apraxia when other cognitive deficits are observed.

  11. ASTROD and ASTROD I -- Overview and Progress

    CERN Document Server

    Ni, Wei-Tou

    2007-01-01

    In this paper, we present an overview of ASTROD (Astrodynamical Space Test of Relativity using Optical Devices) and ASTROD I mission concepts and studies. The missions employ deep-space laser ranging using drag-free spacecraft to map the gravitational field in the solar-system. The solar-system gravitational field is determined by three factors: the dynamic distribution of matter in the solar system; the dynamic distribution of matter outside the solar system (galactic, cosmological, etc.) and gravitational waves propagating through the solar system. Different relativistic theories of gravity make different predictions of the solar-system gravitational field. Hence, precise measurements of the solar-system gravitational field test all these. The tests and observations include: (i) a precise determination of the relativistic parameters beta and gamma with 3-5 orders of magnitude improvement over previous measurements; (ii) a 1-2 order of magnitude improvement in the measurement of G-dot; (iii) a precise determ...

  15. Anthropogenic Drivers of Ecosystem Change: an Overview

    Directory of Open Access Journals (Sweden)

    Gerald C. Nelson

    2006-12-01

    Full Text Available This paper provides an overview of what the Millennium Ecosystem Assessment (MA calls "indirect and direct drivers" of change in ecosystem services at a global level. The MA definition of a driver is any natural or human-induced factor that directly or indirectly causes a change in an ecosystem. A direct driver unequivocally influences ecosystem processes. An indirect driver operates more diffusely by altering one or more direct drivers. Global driving forces are categorized as demographic, economic, sociopolitical, cultural and religious, scientific and technological, and physical and biological. Drivers in all categories other than physical and biological are considered indirect. Important direct drivers include changes in climate, plant nutrient use, land conversion, and diseases and invasive species. This paper does not discuss natural drivers such as climate variability, extreme weather events, or volcanic eruptions.

    Vielva, P

    2010-01-01

    The report of a significant deviation of the CMB temperature anisotropies distribution from Gaussianity (soon after the public release of the WMAP data in 2003) has become one of the most solid WMAP anomalies. This detection grounds on an excess of the kurtosis of the Spherical Mexican Hat Wavelet coefficients at scales of around 10 degrees. At these scales, a prominent feature --located in the southern Galactic hemisphere-- was highlighted from the rest of the SMHW coefficients: the Cold Spot. This article presents a comprehensive overview related to the study of the Cold Spot, paying attention to the non-Gaussianity detection methods, the morphological characteristics of the Cold Spot, and the possible sources studied in the literature to explain its nature. Special emphasis is made on the Cold Spot compatibility with a cosmic texture, commenting on future tests that would help to give support or discard this hypothesis.

    Space radiation presents a hazard to astronauts, particularly those journeying outside the protective influence of the geomagnetosphere. Crews on future missions to Mars will be exposed to the harsh radiation environment of deep space during the transit between Earth and Mars. Once on Mars, they will encounter radiation that is only slightly reduced, compared to free space, by the thin Martian atmosphere. NASA is obliged to minimize, where possible, the radiation exposures received by astronauts. Thus, as a precursor to eventual human exploration, it is necessary to measure the Martian radiation environment in detail. The MARIE experiment, aboard the 2001 Mars Odyssey spacecraft, is returning the first data that bear directly on this problem. Here we provide an overview of the experiment, including introductory material on space radiation and radiation dosimetry, a description of the detector, model predictions of the radiation environment at Mars, and preliminary dose-rate data obtained at Mars.

    Full Text Available A mobile ad hoc network (MANET is a self-configuring of mobile devices network connected without wires and hence MANET has become a very popular technology now days. A MANETS are the networks that are building, when some mobile nodes come in the mobility range of each other for data transfer and communication. In MANET, nodes are not stable hence the communication topology is not stable due to this vulnerable for attacks. MANET devices are connected via wireless links without using an existing network infrastructure or centralized administration due to which MANETs are not able to diverse types of attacks and intrusions. Hence intrusion detection has attracted many researchers. This paper gives an overview and different methods to detect intrusion in MANET.

    Full Text Available Shape memory alloys remember their shape due to thermoelastic martensitic phase transformation. These alloys have advantages in terms of large recoverable strain and these alloys can exert continuous force during use. Equiatomic NiTi, also known as nitinol, has a great potential for use as a biomaterial as compared to other conventional materials due to its shape memory and superelastic properties. In this paper, an overview of recent research and development related to NiTi based shape memory alloys is presented. Applications and uses of NiTi based shape memory alloys as biomaterials are discussed. Biocompatibility issues of nitinol and researchers’ approach to overcome this problem are also briefly discussed.

  5. Weathering of Roofing Materials-An Overview

    Energy Technology Data Exchange (ETDEWEB)

    Berdahl, Paul; Akbari, Hashem; Levinson, Ronnen; Miller, William A.

    2006-03-30

    An overview of several aspects of the weathering of roofing materials is presented. Degradation of materials initiated by ultraviolet radiation is discussed for plastics used in roofing, as well as wood and asphalt. Elevated temperatures accelerate many deleterious chemical reactions and hasten diffusion of material components. Effects of moisture include decay of wood, acceleration of corrosion of metals, staining of clay, and freeze-thaw damage. Soiling of roofing materials causes objectionable stains and reduces the solar reflectance of reflective materials. (Soiling of non-reflective materials can also increase solar reflectance.) Soiling can be attributed to biological growth (e.g., cyanobacteria, fungi, algae), deposits of organic and mineral particles, and to the accumulation of flyash, hydrocarbons and soot from combustion.

  6. The Greek Ethnography. A critical overview

    Directory of Open Access Journals (Sweden)

    Aris Tsantiropoulos

    2014-09-01

    Full Text Available This article presents an overview of Greek ethnography. It argues that ethnography in Greece cannot be seen as separate from its preceding fields of history and folklore studies, alongside Greece itself being viewed as a research field by foreign anthropologists. Because of the late introduction of anthropology in Greece it followed very quickly the main theoretical stream of postmodernism in its view of Greek society. The main argument of this article is that the introduction of postmodernism in Greek Anthropology prevented a dialogue with the pre-existing field research work that had been conducted in Greece by non Greek Ethnographers and Greek Folklorists or Historians. This fact has specific consequences at the epistemological, theoretical and methodological level of contemporary Greek Ethnography.

    Full Text Available Marine snails of the genus Conus are a large family of predatory gastropods with an unparalleled molecular diversity of pharmacologically active compounds in their venom. Cone snail venom comprises of a rich and diverse cocktail of peptide toxins which act on a wide variety of ion channels such as voltage-gated sodium- (NaV, potassium- (KV, and calcium- (CaV channels as well as nicotinic acetylcholine receptors (nAChRs which are classified as ligand-gated ion channels. The mode of action of several conotoxins has been the subject of investigation, while for many others this remains unknown. This review aims to give an overview of the knowledge we have today on the molecular pharmacology of conotoxins specifically interacting with nAChRs along with the structure–function relationship data.

    2008-04-01

    Impulsive-compulsive buying disorder (ICBD) is an impulse control disorder not otherwise specified (ICD-NOS) characterized by impulsive drives and compulsive behaviours (buying unneeded things), personal distress, impaired social and vocational functioning and financial problems. Despite being described in the 19th century, serious attention to ICBD began only in the last decade with the first epidemiological and pharmacological investigation. Biological, social and psychological factors contribute to the aetiology of ICBD. Cognitive-behavioural therapy and selective serotonin re-uptake inhibitors are currently considered the more effective interventions in the treatment of ICBD. The present review aims to provide a broad overview of the epidemiology, aetiology, phenomenology and treatment options of ICBD.

    Kazai, Gabriella; Doucet, Antoine; Landoni, Monica

    This paper provides an overview of the INEX 2008 Book Track. Now in its second year, the track aimed at broadening its scope by investigating topics of interest in the fields of information retrieval, human computer interaction, digital libraries, and eBooks. The main topics of investigation were defined around challenges for supporting users in reading, searching, and navigating the full texts of digitized books. Based on these themes, four tasks were defined: 1) The Book Retrieval task aimed at comparing traditional and book-specific retrieval approaches, 2) the Page in Context task aimed at evaluating the value of focused retrieval approaches for searching books, 3) the Structure Extraction task aimed to test automatic techniques for deriving structure from OCR and layout information, and 4) the Active Reading task aimed to explore suitable user interfaces for eBooks enabling reading, annotation, review, and summary across multiple books. We report on the setup and results of each of these tasks.

    Full Text Available Porphyromonas gingivalis is a Gram-negative oral anaerobe that is involved in the pathogenesis of periodontitis and is a member of more than 500 bacterial species that live in the oral cavity. This anaerobic bacterium is a natural member of the oral microbiome, yet it can become highly destructive (termed pathobiont and proliferate to high cell numbers in periodontal lesions: this is attributed to its arsenal of specialized virulence factors. The purpose of this review is to provide an overview of one of the main periodontal pathogens—Porphyromonas gingivalis. This bacterium, along with Treponema denticola and Tannerella forsythia, constitute the “red complex,” a prototype polybacterial pathogenic consortium in periodontitis. This review outlines Porphyromonas gingivalis structure, its metabolism, its ability to colonize the epithelial cells, and its influence upon the host immunity.

    2010-11-01

    This poster will give an overview of recent results from The Columbia Non-neutral Torus (CNT). CNT was recently reconfigured by repositioning the internal coils, creating magnetic surfaces substantially different from those previously used. Field line mapping, confinement, and stability results will be summarized; they are covered in more detail in adjacent posters. Numerical studies of drift orbits will be presented. Toroidal resonances and electrostatic perturbations can create complicated unconfined orbits in CNT, which can affect confinement negatively but also provides ways of injecting electrons, or positrons. The issue of Debye shielding in a non-neutral plasma is discussed. Debye screening is very different compared to the textbook calculation for a quasineutral plasma. The ability to affect drift orbits with external electrostatic perturbations may be used to inject electrons or positrons across the magnetic surfaces. An update on the plans for an electron-positron plasma experiment will also be given.

    Plasma Medicine is a growing field that is having an impact in several important areas in therapeutic patient care, combining plasma physics, biology, and clinical medicine. Historically, plasmas in medicine were used in electrosurgery for cautery and non-contact hemostasis. Presently, non-thermal plasmas have attained widespread use in medicine due to their effectiveness and compatibility with biological systems. The paper will give a general overview of how low temperature, non-equilibrium, gas plasmas operate, both from physics and biology perspectives. Plasma is commonly described as the fourth state of matter and is typically comprised of charged species, active molecules and atoms, as well as a source of UV and photons. The most active areas of plasma technology applications are in wound treatment; tissue regeneration; inactivation of pathogens, including biofilms; treating skin diseases; and sterilization. There are several means of generating plasmas for use in medical applications, including plasma jets, dielectric barrier discharges, capacitively or inductively coupled discharges, or microplasmas. These systems overcome the former constraints of high vacuum, high power requirements and bulky systems, into systems that use room air and other gases and liquids at low temperature, low power, and hand-held operation at atmospheric pressure. Systems will be discussed using a variety of energy sources: pulsed DC, AC, microwave and radiofrequency, as well as the range of frequency, pulse duration, and gas combinations in an air environment. The ionic clouds and reactive species will be covered in terms of effects on biological systems. Lastly, several commercial products will be overviewed in light of the technology utilized, health care problems being solved, and clinical trial results.
