  10. Extending an evidence hierarchy to include topics other than treatment: revising the Australian 'levels of evidence'.

    Science.gov (United States)

    Merlin, Tracy; Weston, Adele; Tooher, Rebecca

    2009-06-11

    In 1999 a four-level hierarchy of evidence was promoted by the National Health and Medical Research Council in Australia. The primary purpose of this hierarchy was to assist with clinical practice guideline development, although it was co-opted for use in systematic literature reviews and health technology assessments. In this hierarchy interventional study designs were ranked according to the likelihood that bias had been eliminated and thus it was not ideal to assess studies that addressed other types of clinical questions. This paper reports on the revision and extension of this evidence hierarchy to enable broader use within existing evidence assessment systems. A working party identified and assessed empirical evidence, and used a commissioned review of existing evidence assessment schema, to support decision-making regarding revision of the hierarchy. The aim was to retain the existing evidence levels I-IV but increase their relevance for assessing the quality of individual diagnostic accuracy, prognostic, aetiologic and screening studies. Comprehensive public consultation was undertaken and the revised hierarchy was piloted by individual health technology assessment agencies and clinical practice guideline developers. After two and a half years, the hierarchy was again revised and commenced a further 18 month pilot period. A suitable framework was identified upon which to model the revision. Consistency was maintained in the hierarchy of "levels of evidence" across all types of clinical questions; empirical evidence was used to support the relationship between study design and ranking in the hierarchy wherever possible; and systematic reviews of lower level studies were themselves ascribed a ranking. The impact of ethics on the hierarchy of study designs was acknowledged in the framework, along with a consideration of how harms should be assessed. The revised evidence hierarchy is now widely used and provides a common standard against which to initially

    Campbell, C. L.; Brown, C. T. A.; Wood, K.; Moseley, H.

    2016-11-01

    Most existing theoretical models of photodynamic therapy (PDT) assume a uniform initial distribution of the photosensitive molecule, Protoporphyrin IX (PpIX). This is an adequate assumption when the prodrug is systematically administered; however for topical PDT this is no longer a valid assumption. Topical application and subsequent diffusion of the prodrug results in an inhomogeneous distribution of PpIX, especially after short incubation times, prior to light illumination. In this work a theoretical simulation of PDT where the PpIX distribution depends on the incubation time and the treatment modality is described. Three steps of the PpIX production are considered. The first is the distribution of the topically applied prodrug, the second in the conversion from the prodrug to PpIX and the third is the light distribution which affects the PpIX distribution through photobleaching. The light distribution is modelled using a Monte Carlo radiation transfer model and indicates treatment depths of around 2 mm during daylight PDT and approximately 3 mm during conventional PDT. The results suggest that treatment depths are not only limited by the light penetration but also by the PpIX distribution.

Journal of the Medical Library Association, 104(2, 109-117. http://dx.doi.org/10.3163/1536-5050.104.2.004 Abstract Objective – To compare the results of health sciences search queries in three web-scale discovery (WSD services for relevance, duplicate detection, and retrieval of MEDLINE content. Design – Comparative evaluation and bibliometric study. Setting – Six university libraries in the United States of America. Subjects – Three commercial WSD services: Primo, Summon, and EBSCO Discovery Service (EDS. Methods – The authors collected data at six universities, including their own. They tested each of the three WSDs at two data collection sites. However, since one of the sites was using a legacy version of Summon that was due to be upgraded, data collected for Summon at this site were considered obsolete and excluded from the analysis. The authors generated three questions for each of six major health disciplines, then designed simple keyword searches to mimic typical student search behaviours. They captured the first 20 results from each query run at each test site, to represent the first “page” of results, giving a total of 2,086 total search results. These were independently assessed for relevance to the topic. Authors resolved disagreements by discussion, and calculated a kappa inter-observer score. They retained duplicate records within the results so that the duplicate detection by the WSDs could be compared. They assessed MEDLINE coverage by the WSDs in several ways. Using precise strategies to generate a relevant set of articles, they conducted one search from each of the six disciplines in PubMed so that they could compare retrieval of MEDLINE content. These results were cross-checked against the first 20 results from the corresponding query in the WSDs. To aid investigation of overall

    1993-04-01

    This paper describes features, the current status and examples of studies on the metal semi-solidification process. This process provides fine and uniform grain structures without coarse dendrite, internal defects, and segregation. The process uses a low processing pressure that makes uniform processing easier, and can make new composite materials and alloys with new components because of high viscosity in slurry. The thixomolding that combines a semi-melting process with the semi-solidification process is expected of the early realization of its use because it is easier in controlling metal crystal shapes, processing temperatures, and viscosity during processing than in the rheocasting. Research and development efforts in other countries are addressed to developing cryogenic casting processes for mass-produced steel materials aimed at reducing segregation, and studying a process to supply semi-solidified metal slurries to different manufacturing processes to fabricate difficult-to-process materials and functional materials into a near net shape. Studies include identification of relationship between cooling rates and stirring rates affecting crystal shapes, understanding of formability and transformation behavior of semi-solidified metals, and introduction of viscosity inferring equations. 3 figs., 1 tab.

    2013-09-01

    Full Text Available Power transmission facilities in the U.S. are undergoing a transformation due to the increased use of distributed generation sources such as wind and solar power.  The current power grid system is also antiquated and in need of substantial retrofits to make it more efficient and reliable.  The new energy transmission system being designed and built to optimize power delivery is known as “Smart Grid”.  The increased activity in the construction of power transmission facilities and installation of new technologies into the current power system raises potential safety concerns.  Existing construction management curriculum may include general information about safety training, but does not typically include information about this specialized sector.  The objective of this study was to work with industry to identify key safety topics appropriate for inclusion in an introductory industrial construction course.  Results of interviews with industry identified numerous hazards that are not typically covered in typical construction curricula.  A joint undergraduate and graduate course in industrial construction was created to address these and additional concepts. A survey of the students was performed to determine the effectiveness of the course and also to determine their thoughts about the smart grid technologies and safety training. Information on electrical system hazards is presented along with results of the student surveys.

    The Science Technology Society (STS) approach is a major science education reform through which a scientifically literate citizen could be produced. The teaching of science through STS approach is centered on science and technology related issues and problems. The purpose of this study was to analyze five earth science textbooks published in the 1990's for their inclusion of twelve sciences and technology related issues and problems and for their inclusion of activities focused on STS. The selected earth science textbooks were; Scott Foresman, Heath, Holt, Merrill and Prentice-Hall. The targeted twelve issues and problems were identified by Bybee (1987), as the most important global science and technology related issues and problems. The numbers of full text pages devoted to each topic were determined by classifying each segment to one of the targeted topics. In addition, the numbers of STS activities were also determined by using criteria developed for this study. ANOVA statistical analyses and t-tests showed that the analyzed earth science textbooks treated the studied STS issues and problems and treated the STS activities differently. It was found that six of the studied issues and problems were constantly receiving more attention in all the analyzed earth science textbooks than the rest of the topics. These topics were; Air Quality and Atmosphere, Energy Shortages, Water Resources, Land Use, Hazardous Substances, and Mineral Resources. The overall results revealed that only an average of 8.82% of the text pages in all the analyzed earth science textbooks were devoted to STS topics and 5.49% of the activities in all the analyzed earth science textbooks were focused on STS topics. However, none of the activities focused on STS topics were presented in STS approach as defined by NSTA. The percentage of STS topics inclusion and the percentage of activities focused on STS topics were considered to be very low. Accordingly, the objectives and goals of STS approach

    2006-07-01

    The reasons for treating CBM water, end uses, reverse osmosis, pretreatment for reverse osmosis, and Newpark case studies are described. CBM water can be treated to make it suitable for injection, re-use, irrigation, or surface discharge. Usually the total dissolved solids (TDS) must be reduced by ion exchange or reverse osmosis with pretreatment. The concept of reverse osmosis and three types of applicable membrane processes are described: microfiltration and ultrafiltration, nanofiltration, and electrodialysis. The technologies used for pretreatment depend on the water quality and treatment goals, e.g. coagulation, flocculation and sand media filtration, softening, ion exchange, and nanofiltration. A Newpark case study is described for a water treatment plant at Boulder, Wyoming where evaporation was replaced by cavitation technology. The suitability of various treatment methods for Alberta CBM water is discussed. 21 figs., 1 tab.

    There is growing awareness of the impact of human activity on the climate and the need to stem this impact. Public health care decision makers from Sweden and the United Kingdom have started examining environmental impacts when assessing new technologies. This article considers the case for incorporating environmental impacts into the health technology assessment (HTA) process and discusses the associated challenges. Two arguments favor incorporating environmental impacts into HTA: 1) environmental changes could directly affect people's health and 2) policy decision makers have broad mandates and objectives extending beyond health care. Two types of challenges hinder this process. First, the nascent evidence base is insufficient to support the accurate comparison of technologies' environmental impacts. Second, cost-utility analysis, which is favored by many HTA agencies, could capture some of the value of environmental impacts, especially those generating health impacts, but might not be suitable for addressing broader concerns. Both cost-benefit and multicriteria decision analyses are potential methods for evaluating health and environmental outcomes, but are less familiar to health care decision makers. Health care is an important and sizable sector of the economy that could warrant closer policy attention to its impact on the environment. Considerable work is needed to track decision makers' demands, augment the environmental evidence base, and develop robust methods for capturing and incorporating environmental data as part of HTA.

  10. Using Technology to Support Discussions on Sensitive Topics in the Study of Business Ethics

    Directory of Open Access Journals (Sweden)

    Michelle WL Fong

    2015-06-01

    Full Text Available There is a dearth of research into teaching strategies and learning approaches for units involving sensitive topics that can provoke an emotional response in students. In a business ethics unit, attempts to strike a balance between conceptual knowledge and theory and skills training can be challenging because the unit can involve personal, sensitive or controversial topics. When engaging in deep and meaningful face-to-face discussion, students may unknowingly divulge personal opinions that they later regret or become identified with by other students over time. Value-laden topics may also lead to clashes between students if face-to-face discussions are not managed properly. This paper considers the use of technology in blended learning to provide an optimal learning environment for student discussion on sensitive topics via role-play and simulation in a first-year business ethics unit. The Audience Response System (ARS, online discussion boards and blogs, and wikis are assessed for their suitability in supporting online role-play and simulation. Among these online tools, asynchronous online discussion boards and blogs are the ideal tools for supporting student discussion on sensitive topics in online role-play and simulation.

  12. High-efficiency photovoltaic technology including thermoelectric generation

    Science.gov (United States)

    Fisac, Miguel; Villasevil, Francesc X.; López, Antonio M.

    2014-04-01

    Nowadays, photovoltaic solar energy is a clean and reliable source for producing electric power. Most photovoltaic systems have been designed and built up for use in applications with low power requirements. The efficiency of solar cells is quite low, obtaining best results in monocrystalline silicon structures, with an efficiency of about 18%. When temperature rises, photovoltaic cell efficiency decreases, given that the short-circuit current is slightly increased, and the open-circuit voltage, fill factor and power output are reduced. To ensure that this does not affect performance, this paper describes how to interconnect photovoltaic and thermoelectric technology into a single structure. The temperature gradient in the solar panel is used to supply thermoelectric cells, which generate electricity, achieving a positive contribution to the total balance of the complete system.

    Ashby, Joe E.

    Lab exercises are a pedagogically essential component of engineering and technology education. Distance education remote labs are being developed which enable students to access lab facilities via the Internet. Collaboration, students working in teams, enhances learning activity through the development of communication skills, sharing observations and problem solving. Web meeting communication tools are currently used in remote labs. The problem identified for investigation was that no standards of practice or paradigms exist to guide remote lab designers in the selection of collaboration tools that best support learning achievement. The goal of this work was to add to the body of knowledge involving the selection and use of remote lab collaboration tools. Experimental research was conducted where the participants were randomly assigned to three communication treatments and learning achievement was measured via assessments at the completion of each of six remote lab based lessons. Quantitative instruments used for assessing learning achievement were implemented, along with a survey to correlate user preference with collaboration treatments. A total of 53 undergraduate technology students worked in two-person teams, where each team was assigned one of the treatments, namely (a) text messaging chat, (b) voice chat, or (c) webcam video with voice chat. Each had little experience with the subject matter involving automation, but possessed the necessary technical background. Analysis of the assessment score data included mean and standard deviation, confirmation of the homogeneity of variance, a one-way ANOVA test and post hoc comparisons. The quantitative and qualitative data indicated that text messaging chat negatively impacted learning achievement and that text messaging chat was not preferred. The data also suggested that the subjects were equally divided on preference to voice chat verses webcam video with voice chat. To the end of designing collaborative

    Because viable skin possesses enzyme activities, including those involved in the metabolism of xenobiotics, the extent to which cutaneous metabolism may influence the percutaneous fate of topically applied chemicals in the skin was examined in mammalian skin maintained as short-term organ cultures. Skin samples from mouse, rat, rabbit, guinea pig, marmoset, and man were examined. The results from studies with benzo(a)pyrene (BP) and testosterone showed that, in all species, metabolic viability was a major factor involved in the in vitro skin permeation of surface-applied chemicals. Permeation was accompanied by extensive cutaneous first pass metabolism; both parent compounds and a full spectrum of metabolites were found in the receptor fluid from viable skin preparations. However, in previously frozen nonviable skin preparations, essentially only unchanged parent compounds were detected in the receptor fluid. Permeation of BP and testosterone was highest in mouse skin, and significant species variations in the metabolite profiles were observed. Studies with mouse skin also demonstrated that induction of cutaneous drug-metabolizing enzymes can result in a two- to threefold increase in the in vitro permeation of topical BP, and a significant reduction in permeation was observed when KCN was added to the perfusion medium. These results indicate that diffusional and metabolic processes are intimately involved in the percutaneous fate of surface-applied chemicals. The relative importance of these processes is dependent upon the physicochemical properties of the compounds and the metabolic capabilities of the skin toward the compounds in question. Furthermore, these findings suggest that meaningful in vitro studies on skin absorption should consider both diffusion and cutaneous biotransformation of the applied compound.

    The ``Environmental Management Technology Leveraging Initiative,`` a cooperative agreement between the Global Environment and Technology Foundation and the Department of Energy-Morgantown Energy Technology Center, has completed its second year. This program, referred to as the Global Environmental Technology Enterprise (GETE) is an experiment to bring together the public and private sectors to identify, formulate, promote and refine methods to develop more cost-effective clean-up treatments. Working closely with Department of Energy officials, National Laboratory representatives, business people, academia, community groups, and other stakeholders, this program attempts to commercialize innovative, DOE-developed technologies. The methodology to do so incorporates three elements: business assistance, information, and outreach. A key advance this year was the development of a commercialization guidance document which can be used to diagnose the commercialization level and needs for innovative technologies.

    The deployment of innovative DOE-EM technologies could provide more cost-effective treatments than remediation technologies and methods currently in use. By building partnerships between the public and private sectors, the technological expertise of federal researchers and engineers and the commercial incentive of industrialists and other non-government interests can combine to help move these technologies {open_quotes}off the shelf{close_quote} and toward use at contaminated sites. The GETE approach to achieving this end is: (1) to develop a process which identifies and assesses DOE-developed technologies from the perspective of commercial marketability; assists in bringing these technologies to the attention of the private sector; and aids, if necessary, in business planning and start-up activities, (2) to establish a state-of-the-art electronic communications system, the Global Network of Environment & Technology (GNET), to disseminate information on DOE-developed technologies, as well as information on capital and financing availability, regulatory matters, and commercialization objectives to potential business partners and others, and (3) to undertake public participation and outreach activities designed to address barrier reduction and public acceptance issues.

    In 2016, the Office of International Nuclear Safeguards at the National Nuclear Security Administration (NNSA) within the Department of Energy (DOE) commissioned the Pacific Northwest National Laboratory (PNNL) to explore the potential implications of the digital currency bitcoin and its underlying technologies on the safeguards system. The authors found that one category of technologies referred to as Shared Ledger Technology (SLT) offers a spectrum of benefits to the safeguards system. While further research is needed to validate assumptions and findings in the paper, preliminary analysis suggests that both the International Atomic Energy Agency (IAEA) and Member States can use SLT to promote efficient, effective, accurate, and timely reporting, and increase transparency in the safeguards system without sacrificing confidentiality of safeguards data. This increased transparency and involvement of Member States in certain safeguards transactions could lead to increased trust and cooperation among States and the public, which generates a number of benefits. This paper describes these benefits and the analytical framework for assessing SLT applications for specific safeguards problems. The paper will also describe other national security areas where SLT could provide benefits.

    2013-01-01

    Over a century ago, a pioneering researcher cleverly devised a means to measure how much weight the horned passalus beetle, Odontotaenius disjunctus (Illiger) (Coleoptera: Passalidae), could pull using a series of springs, pulleys, and careful observation. The technology available in modern times now allows for more rigorous data collection on this topic, which could have a number of uses in scientific investigations. In this study, an apparatus was constructed using a dynamometer and a data logger in an effort to ascertain the pulling strength of this species. By allowing beetles to pull for 10 min, each beetle's mean and maximum pulling force (in Newtons) were obtained for analyses, and whether these measures are related was determined. Then, whether factors such as body length, thorax size, horn size, or gender affect either measure of strength was investigated. Basic body measurements, including horn size, of males versus females were compared. The measurements of 38 beetles (20 females, 18 males) showed there was no difference in overall body length between sexes, but females had greater girth (thorax width) than males, which could translate into larger muscle mass. A total of 21 beetles (10 females, 11 males) were tested for pulling strength. The grand mean pulling force was 0.14 N, and the grand mean maximum was 0.78 N. Despite the fact that beetles tended to pull at 20% of their maximum capacity most of the time, and that maximum force was over 5 times larger than the mean force, the 2 measures were highly correlated, suggesting they may be interchangeable for research purposes. Females had twice the pulling strength (both maximum and mean force) as males in this species overall, but when the larger thorax size of females was considered, the effect of gender was not significant. Beetle length was not a significant predictor of pulling force, but horn size was associated with maximum force. The best predictor of both measures of strength appeared to be

    Mesenchymal stem cells (MSCs) are adult stem cells which show differentiation capabilities toward various cell lineages. We have already used MSCs for treatments of osteoarthritis, bone necrosis and bone tumor. For this purpose, culture expanded MSCs were combined with various ceramics and then implanted. Because of rejection response to allogeneic MSC implantation, we have utilized patients' own MSCs for the treatment. Bone marrow is a good cell source of MSCs, although the MSCs also exist in adipose tissue. When comparing osteogenic differentiation of these MSCs, bone marrow MSCs show more extensive bone forming capability than adipose MSCs. Thus, the bone marrow MSCs are useful for bone tissue regeneration. However, the MSCs show limited proliferation and differentiation capabilities that hindered clinical applications in some cases. Recent advances reveal that transduction of plural transcription factors into human adult cells results in generation of new type of stem cells called induced pluripotent stem cells (iPS cells). A drawback of the iPS cells for clinical applications is tumor formation after their in vivo implantation; therefore it is difficult to use iPS cells for the treatment. To circumvent the problem, we transduced a single factor of either SOX2 or NANOG into the MSCs and found high proliferation as well as osteogenic differentiation capabilities of the MSCs. The stem cells could be combined with bioceramics for clinical applications. Here, we summarize our recent technologies using adult stem cells in viewpoints of bone tissue regeneration.

    Ulceration of the foot in diabetes is common and disabling, and frequently leads to amputation of the leg. The pathogenesis of foot ulceration is complex, clinical presentation variable and management requires early expert assessment. Despite treatment, ulcers readily become chronic wounds. Chronic wounds are those that remain in a chronic inflammatory state failing a normal healing process patterns. This is partially caused by inefficient eradication of opportunistic pathogens like Pseudomonas aeruginosa. We propose its control or eradication will promote wound healing. Lactobacillus plantarum cultures supernatants (LAPS) shows antipathogenic and pro-healing properties. The main objective was to design two pharmaceutical dosage forms by using LAPS as active pharmaceutical ingredient and to perform its quality control, in vitro activity conservation tests and human trials (safety evaluation). Both selected formulations reach the technological quality expected for 120 days, shows adequate occlusive characteristics and proper adhesion to human skin. From the in vitro release assays were found that LAPS shows adequate release from matrix and maintain its antimicrobial and anti-biofilm activity. First human trials were developed and neither edema nor erythema on healthy skin voluntaries was found. We conclude that C80 and C100 are adequate for their use in future clinical trials to demonstrate a comprehensive therapeutic effectiveness in ischemic chronic wounds.

    Contamination in low permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, pump and treat rather ineffective when applied to law permeability soils present at many contaminated sites. The Lasagna technology is an integrated in-situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil and electro-osmosis is utilized to move the contaminants back and forth through those zones until the treatment is completed. The general concept of the technology is to use electrokinetics to move contaminants from the soils into {open_quotes}treatment zones{close_quotes} where the contaminants can be removed from the water by either adsorption or degradation. The focus of technical task No. 7 was to optimize the conditions required for electro-osmotic movement of contaminants and microbial degradation in the treatment zones. This topical report summarizes the results of aerobic microbial research performed to evaluate the feasibility of incorporating the chemical-degrading organisms into biotreatment zones in laboratory-scale electro-osmosis units and to demonstrate the combination of electrokinetics and aerobic microbial degradation for the removal of contaminants from clay. Also included in this report are the results of investigating microbial movement during electro-osmosis and studies involving the optimization of the microbial support matrix in the biozone. The Stanford study was conducted in order to obtain a better understanding of rates of anaerobic reductive dehalogenation of TCE to ethylene and of factors affecting these rates in order to determine the potential for application of TCE biodegradation as part of the Lasagna technology.

    Recognizing the potential impacts of sour gas plant operations on the subsurface environment, the Canadian Association of Petroleum Producers (CAPP) and Environment Canada initiated a multiphase study focusing on research related to the development and demonstration of remedial technologies for soil and groundwater contamination at these facilities. Research performed under this project was designed to supplement and be coordinated with research activities being conducted at an operational sour gas plant located in Rocky Mountain House, Alberta, Canada. These research tasks included hydrogeological site characterization, subsurface contaminant characterization, ex situ treatment of groundwater, and subsurface remediation of residual contamination in the unsaturated zone. Ex situ treatment of groundwater included evaluations of air stripping, steam stripping, advanced oxidation, and biological treatment, as well as the development of an artificial freeze crystallization process. Soil vapor extraction was evaluated as a technique to address residual contamination in the unsaturated zone.

  4. Robotic technologies of the Flight Telerobotic Servicer (FTS) including fault tolerance

    Science.gov (United States)

    Chladek, John T.; Craver, William M.

    1994-01-01

    The original FTS concept for Space Station Freedom (SSF) was to provide telerobotic assistance to enhance crew activity and safety and to reduce crew EVA (Extra Vehicular Activity) activity. The first flight of the FTS manipulator systems would demonstrate several candidate tasks and would verify manipulator performance parameters. These first flight tasks included unlocking a SSF Truss Joint, mating/demating a fluid coupling, contact following of a contour board, demonstrating peg-in-hole assembly, and grasping and moving a mass. Future tasks foreseen for the FTS system included ORU (Orbit Replaceable Unit) change-out, Hubble Space Telescope Servicing, Gamma Ray Observatory refueling, and several in-situ SSF servicing and maintenance tasks. Operation of the FTS was planned to evolve from teleoperation to fully autonomous execution of many tasks. This wide range of mission tasks combined with the desire to evolve toward fully autonomy forced several requirements which may seen extremely demanding to the telerobotics community. The FTS requirements appear to have been created to accommodate the open-ended evolution plan such that operational evolution would not be impeded by function limitations. A recommendation arising from the FTS program to remedy the possible impacts from such ambitious requirements is to analyze candidate robotic tasks. Based on these task analyses, operational impacts against development impacts were weighed prior to requirements definition. Many of the FTS requirements discussed in the following sections greatly influenced the development cost and schedule of the FTS manipulator. The FTS manipulator has been assembled at Martin Marietta and is currently in testing. Successful component tests indicate a manipulator which achieves unprecedented performance specifications.

    Ultrasonography (US) has been used in medical imaging for over half a century. Current US scanners are based largely on the same basic principles used in the initial devices for human imaging. Modern equipment uses a pulse-echo approach with a brightness-mode (B-mode) display. Fundamental aspects of the B-mode imaging process include basic ultrasound physics, interactions of ultrasound with tissue, ultrasound pulse formation, scanning the ultrasound beam, and echo detection and signal processing. Recent technical innovations that have been developed to improve the performance of modern US equipment include the following: tissue harmonic imaging, spatial compound imaging, extended field of view imaging, coded pulse excitation, electronic section focusing, three-dimensional and four-dimensional imaging, and the general trend toward equipment miniaturization. US is a relatively inexpensive, portable, safe, and real-time modality, all of which make it one of the most widely used imaging modalities in medicine. Although B-mode US is sometimes referred to as a mature technology, this modality continues to experience a significant evolution in capability with even more exciting developments on the horizon.

    Genomics and proteomics have emerged as key technologies in biomedical research, resulting in a surge of interest in training by investigators keen to incorporate these technologies into their research. At least two types of training can be envisioned in order to produce meaningful results, quality publications and successful grant applications: (1) immediate short-term training workshops and (2) long-term graduate education or visiting scientist programs. We aimed to fill the former need by providing a comprehensive hands-on training course in genomics, proteomics and informatics in a coherent, experimentally-based framework. This was accomplished through a National Heart, Lung, and Blood Institute (NHLBI)-sponsored 10-day Genomics and Proteomics Hands-on Workshop held at National Jewish Health (NJH) and the University of Colorado School of Medicine (UCD). The course content included comprehensive lectures and laboratories in mass spectrometry and genomics technologies, extensive hands-on experience with instrumentation and software, video demonstrations, optional workshops, online sessions, invited keynote speakers, and local and national guest faculty. Here we describe the detailed curriculum and present the results of short- and long-term evaluations from course attendees. Our educational program consistently received positive reviews from participants and had a substantial impact on grant writing and review, manuscript submissions and publications.

    Two vesicular colloidal carriers, ethosomes® and transfersomes® were proposed for the topical delivery of linoleic acid, an active compound used in the therapeutic treatment of hyperpigmentation disorders, i.e. melasma, which is characterized by an increase of the melanin production in the epidermis. Dynamic light scattering was used for the physicochemical characterization of vesicles and mean size, size distribution and zeta potential were evaluated. The stability of formulations was also evaluated using the Turbiscan Lab® Expert based on the analysis of sample transmittance and photon backscattering. Ethosomes® and transfersomes® were prepared using Phospholipon 100 G®, as the lecithin component, and ethanol and sodium cholate, as edge activator agents, respectively. Linoleic acid at 0.05% and 0.1% (w/v) was used as the active ingredient and entrapped in colloidal vesicles. Technological parameters, i.e. entrapment efficacy, drug release and permeation profiles, were also investigated. Experimental findings showed that physicochemical and technological features of ethosomes® and transfersomes® were influenced by the lipid composition of the carriers. The percutaneous permeation experiments of linoleic acid-loaded ethosomes® and transfersomes® through human stratum corneum-epidermidis membranes showed that both carriers are accumulated in the skin membrane model as a function of their lipid compositions. The findings reported in this investigation showed that both vesicular carriers could represent a potential system for the topical treatment of hyperpigmentation disorders.

    Full Text Available The main objective of the work is to test and implement modern interactive methods in the field of medical education, namely the method of cooperative groups into the educational process of the Department of General Surgery of SI "DMA MH" and to determine its efficacy by the example of class on the topic "Burns, frostbites, electrical trauma. Diagnosis, first aid, medical treatment”. The method is used to find similarities in different patterns of giving medical care to patients with burns, frostbites and electric trauma. Learning activity is divided into three stages. Stage 1: the teacher divides the students into four groups and gives a task to each group. Stage 2: each group announces the results and presents them in the standardized format. After the discussion the proper decision on the common features of the first aid, treatment, and the algorithm of action is made. Stage 3: the groups share results of the previous clinical experience, sum up, solve situational tasks and tests of level III. The method of co-operative groups allows to increase the motivation of students in the learning process, causes more efficient and thorough acquiring of the material, promotes development of clinical thinking, develops the urge towards collaboration and collective responsibility, favors the development of positive personal qualities of a future professional doctor.

    Acne is a multifactorial inflammatory skin disease with high prevalence. In this work, the potential of 3D printing to produce flexible personalised-shape anti-acne drug (salicylic acid) loaded devices was demonstrated by two different 3D printing (3DP) technologies: Fused Deposition Modelling (FDM) and stereolithography (SLA). 3D scanning technology was used to obtain a 3D model of a nose adapted to the morphology of an individual. In FDM 3DP, commercially produced Flex EcoPLA™ (FPLA) and polycaprolactone (PCL) filaments were loaded with salicylic acid by hot melt extrusion (HME) (theoretical drug loading - 2% w/w) and used as feedstock material for 3D printing. Drug loading in the FPLA-salicylic acid and PCL-salicylic acid 3D printed patches was 0.4% w/w and 1.2% w/w respectively, indicating significant thermal degradation of drug during HME and 3D printing. Diffusion testing in Franz cells using a synthetic membrane revealed that the drug loaded printed samples released printed as a nose-shape mask by FDM 3DP, but the PCL-salicylic acid filament was not. In the SLA printing process, the drug was dissolved in different mixtures of poly(ethylene glycol) diacrylate (PEGDA) and poly(ethylene glycol) (PEG) that were solidified by the action of a laser beam. SLA printing led to 3D printed devices (nose-shape) with higher resolution and higher drug loading (1.9% w/w) than FDM, with no drug degradation. The results of drug diffusion tests revealed that drug diffusion was faster than with the FDM devices, 229 and 291μg/cm(2) within 3h for the two formulations evaluated. In this study, SLA printing was the more appropriate 3D printing technology to manufacture anti-acne devices with salicylic acid. The combination of 3D scanning and 3D printing has the potential to offer solutions to produce personalised drug loaded devices, adapted in shape and size to individual patients.

    Full Text Available Melasma is a common hypermelanotic disorder affecting the face that is associated with considerable psychological impacts. The management of melasma is challenging and requires a long-term treatment plan. In addition to avoidance of aggravating factors like oral pills and ultraviolet exposure, topical therapy has remained the mainstay of treatment. Multiple options for topical treatment are available, of which hydroquinone (HQ is the most commonly prescribed agent. Besides HQ, other topical agents for which varying degrees of evidence for clinical efficacy exist include azelaic acid, kojic acid, retinoids, topical steroids, glycolic acid, mequinol, and arbutin. Topical medications modify various stages of melanogenesis, the most common mode of action being inhibition of the enzyme, tyrosinase. Combination therapy is the preferred mode of treatment for the synergism and reduction of untoward effects. The most popular combination consists of HQ, a topical steroid, and retinoic acid. Prolonged HQ usage may lead to untoward effects like depigmentation and exogenous ochronosis. The search for safer alternatives has given rise to the development of many newer agents, several of them from natural sources. Well-designed controlled clinical trials are needed to clarify their role in the routine management of melasma.

    Contamination in low-permeability soils poses a significant technical challenge for in situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in situ treatments such as bioremediation, vapor extraction, pump and treat rather ineffective when applied to low-permeability soils present at many contaminated sites. The technology is an integrated in situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil and electro-osmosis is used to move the contaminants back and forth through those zones until the treatment is completed. The present Draft Topical Report for Task No. 9 summarizes laboratory investigations into TCE degradation using nonbiological methods. These studies were conducted by the General Electric Company. The report concentrates on zero valent iron as the reducing agent and presents data on TCE and daughter product degradation rates in batch experiments, column studies, and electroosmotic cells. It is shown that zero valent iron effectively degrades TCE in electroosmotic experiments. Daughter product degradation and gas generation are shown to be important factors in designing field scale treatment zones for the Lasagna{trademark} process.

    Contamination in low permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, pump and treat rather ineffective when applied to low permeability soils present at many contaminated sites. The technology is an integrated in-situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil and electro-osmosis is utilized to move the contaminants back and forth through those zones until the treatment is completed. This topical report presents the results of evaluations by E.I. duPont de Nemours and Co., Inc. of treatment zone and electrode emplacement alternatives for use in the integrated treatment process. Specifically, the scope of this study was limited to vertical configuration emplacements. Several promising alternatives were identified ranging from approaches involving standard excavation techniques to relatively specialized geotechnical construction methods which could be modified for the treatment zone emplacement purpose. Information developed in this report is designed to help the user select the most promising emplacement method(s) for a given site on the basis of (1) depth of emplacement, and (2) restrictions on handling excavated soils. Advantages, disadvantages, and estimated costs are identified for each alternative, and possible bases for improvement and cost reduction through further development are described.

    Graves, A. Palmer

    This study examines the effect of increasing the visual complexity used in computer assisted instruction in general chemistry. Traditional recitation instruction was used as a control for the experiment. One tutorial presented a chemistry topic using 3-D animation showing molecular activity and symbolic representation of the macroscopic view of a chemical phenomenon. A second tutorial presented the same topic but simultaneously presented students with a digital video movie showing the phenomena and 3-D animation showing the molecular view of the phenomena. This experimental set-up was used in two different experiments during the first semester of college level general chemistry course. The topics covered were the molecular effect of heating water through the solid-liquid phase change and the kinetic molecular theory used in explaining pressure changes. The subjects used in the experiment were 236 college students enrolled in a freshman chemistry course at a large university. The data indicated that the simultaneous presentation of digital video, showing the solid to liquid phase change of water, with a molecular animation, showing the molecular behavior during the phase change, had a significant effect on student particulate understanding when compared to traditional recitation. Although the effect of the KMT tutorial was not statistically significant, there was a positive effect on student particulate understanding. The use of computer tutorial also had a significant effect on student attitude toward their comprehension of the lesson.

    For environmental and health effects due to increasing levels of pollution in the atmosphere, it is necessary to develop environmentally sound technologies for the treatment of greenhouse gases (CO{sub 2}, CH{sub 4}, CFC, etc.) and acid gases (SOx, NOx, etc.). Specifically, advanced technology for CO{sub 2} capturing is currently one of the most important environmental issues in worldwide. {sup 14}CO{sub 2}, specially which has been gradually emerging issue in the nuclear facilities, is generated about 330 ppm from the CANDU (Canadian Deuterium Uranium Reactor) nuclear power plant and the DUPIC (Direct Use of spent PWR fuel in CANDU reactors) process which is the process of spent fuel treatment. For this purpose, it is necessary to develop the most efficient treatment technology of CO{sub 2} capture by various lime materials in semi- or dry process, it should be also considering a removal performance, waste recycling and safety of disposal. In order to develop a highly active slaked lime as a sorbent for CO{sub 2} and high temperature desulfurization, macroporous slaked lime is necessarily prepared by modified swelling process and equipment, which was developed under carrying out this project. And also for the optimal removal process of off-gases the removal performance tests of various sorbents and the effects of relative humidity and bed depth on the removal capacity must be considered.

    The first signs of facial skin photo-aging often occur in the skin of the periorbital area and include sagging, loss of firmness and definition, and sallowness. Epidermal wounds have been shown to alter the trans-epithelial electrical potential creating an electric signal that directs cell migration in epithelial wound healing; this electric field declines sharply with age. A topical galvanic zinc-copper complex, which couples elemental zinc and copper to create a biomimetic electric field, has demonstrated anti-inflammatory activity and extracellular matrix improvement in vitro, including collagen and elastin production. To evaluate the efficacy and tolerability of a galvanic zinc-copper complex on photo-aging parameters in a randomized, double-blind, placebo-controlled clinical trial. In this eight-week study, women (40-65 years) with mild to moderate photo-aging were randomized to use placebo or 1 of 3 galvanic zinc-copper complex compositions (gel and activating moisturizer). Efficacy evaluations included clinical grading, specialized clinical imaging, and subject self-assessments performed at baseline, 15-30 minutes after product application and after 1, 2, 4, and 8 weeks. Tolerability was based on adverse events and clinical grading of irritation. Significance was set at P?0.05 versus baseline and between treatment groups. The study was completed by 124 women. Compositions containing the galvanic zinc-copper complex showed statistically significant clinical improvements versus placebo and baseline rapidly (15-30 min) after application and through week 8. Clinical grading showed significant improvement versus placebo in skin radiance and under-eye dark circles 15-30 minutes after first application with continued improvement through week 8, and in overall photo-damage, fine lines, lifted appearance of the eyes, and under-eye wrinkles starting after two weeks and continuing through week 8. Test compositions were well tolerated. This galvanic zinc-copper complex

    The aim of the present context was to develop and evaluate a Kolliphor® P407-based transdermal gel formulation of diclofenac sodium by hot melt extrusion (HME) technology; central composite design was used to optimize the formulation process. In this study, we have explored first time ever HME as an industrially feasible and continuous manufacturing technology for the manufacturing of gel formulation using Kolliphor® P407 and Kollisolv® PEG400 as a gel base. Diclofenac sodium was used as a model drug. The HME parameters such as feeding rate, screw speed, and barrel temperature were crucial for the semisolid product development, and were optimized after preliminary trials. For the processing of the gel formulation by HME, a modified screw design was used to obtain a uniform product. The obtained product was evaluated for physicochemical characterization such as differential scanning calorimetry (DSC), X-ray diffraction (XRD), pH measurement, rheology, surface tension, and texture profile analysis. Moreover, it was analyzed for general appearance, spreadibility, surface morphology, and drug content. The optimized gel formulation showed homogeneity and transparent film when applied on a glass slide under microscope, pH was 7.02 and uniform drug content of 100.04 ± 2.74 (SD = 3). The DSC and XRD analysis of the HME gel formulation showed complete melting of crystalline API into an amorphous form. The Kolliphor® P407 and Kollisolv® PEG400 formed excellent gel formulation using HME with consistent viscoelastic properties of the product. An improved drug release was found for the HME gel, which showed a 100% drug release than that of a marketed product which showed only 88% of drug release at the end of 12 h. The Flux value of the HME gel was 106 than that of a marketed formulation, which showed only about 60 value, inferring a significant difference (P < 0.05) at the end of 1 h. This study demonstrates a novel application of the hot melt extrusion

    Alberta-based Earth Energy Resources has chosen Utah for its first major oilsand development project. Utah has excellent oil sands resources, but most cannot be economically extracted using conventional methods. The president of Earth Energy Resources has proposed to use new technologies, processes and workflow methods to make resource extraction economically viable. The company currently holds a 100 percent interest in 3,170 hectares under lease from the State of Utah School and Institutional Trust Lands Administration (SITLA) in the PR Spring deposit. The recoverable high-quality bitumen is estimated at 250 million barrels. The oil sands in Utah are disaggregated and spread out over a relatively wide area. The bitumen quality is very similar to that found in the Athabasca deposit, but it has a much lower sulphur content. Earth Energy Resources plans on using the Ophus Process which involves a series of small 2,000 barrel per day production facilities that can be easily set up, and moved as the resources in one particular area are recovered. Production could be expanded as needed by the addition of more facilities. An environmentally sound citrus-based extraction chemical will replace much of the mechanical energy and caustic soda mixture used in the Clark Process. The new energy and water efficient process will significantly reduce the quantity of middlings produced in the process, thereby eliminating the need for tailings ponds and reducing environmental impacts. 1 fig.

    In recent years, Russia adopted a policy towards increasing of the share of renewable energy in total amount of used energy, albeit with some delay comparing to the EU countries and the USA. It was expected that the use of biofuels over time will reduce significantly the dependency of Russian economy on fossil fuels, increase its competitiveness, and increase Russian contribution to the prevention of global climate changes. Russia has significant bio-energy potential and resources which are characterized by great diversity due to the large extent of the territory, which require systematic studies and environmental assessment of used bio-energy technologies. Results of research carried at the Laboratory of agroecological monitoring, modeling and prediction of ecosystems RSAU-MTAA demonstrated significant differences in the assessment of the environmental, economic and social effects of biofuel production and use, depending on the species of bio-energy crops, regional soil-ecological and agro-climatic characteristics, applied farming systems and production processes. The total area of temporarily unused and fallow land, which could be allocated to the active agricultural use in Russia, according to various estimates, ranges from 20 to 33 million hectares, which removes the problem, typical of most European countries, of adverse agro-ecological changes in land use connected with the expansion of bio-energy crops cultivation. However, the expansion of biofuel production through the use of fallow land and conversion of natural lands has as a consequence the problem of greenhouse gas emissions due to land use changes, which, according to FAO, could be even higher than CO2 emission from fossil fuels for some of bio-energy raw materials and production systems. Assessment of the total impacts of biofuels on greenhouse gas emissions in the Russian conditions should be based on regionally adapted calculations of flows throughout the entire life cycle of production, taking

  7. Modifying the Sleep Treatment Education Program for Students to include technology use (STEPS-TECH): Intervention effects on objective and subjective sleep outcomes.

    University students often have sleep issues that arise from poor sleep hygiene practices and technology use patterns. Yet, technology-related behaviors are often neglected in sleep hygiene education. This study examined whether the Sleep Treatment Education Program for Students-modified to include information regarding managing technology use (STEPS-TECH)-helps improve both subjective and objective sleep outcomes among university students. Results of an experimental study among 78 university students showed improvements in objective indicators of sleep quantity (total sleep time) and sleep quality (less awakenings) during the subsequent week for students in the STEPS-TECH intervention group compared to a control group. Exploratory analyses indicated that effects were driven by improvements in weekend days immediately following the intervention. There were also no intervention effects on subjective sleep quality or quantity outcomes. In terms of self-reported behavioral responses to educational content in the intervention, there were no group differences in sleep hygiene practices or technology use before bedtime. However, the intervention group reported less technology use during sleep periods than the control group. These preliminary findings suggest that STEPS-TECH may be a useful educational tool to help improve objective sleep and reduce technology use during sleep periods among university students.

  10. A study of toxic emissions from a coal-fired power plant utilizing the SNOX innovative clean coal technology demonstration. Volume 1, Sampling/results/special topics: Final report

    Energy Technology Data Exchange (ETDEWEB)

    1994-07-01

    This study was one of a group of assessments of toxic emissions from coal-fired power plants, conducted for DOE during 1993. The motivation for those assessments was the mandate in the 1990 Clean Air Act Amendments that a study be made of emissions of hazardous air pollutants (HAPs) from electric utilities. The report is organized in two volumes. Volume 1: Sampling describes the sampling effort conducted as the basis for this study; Results presents the concentration data on HAPs in the several power plant streams, and reports the results of evaluations and calculations conducted with those data; and Special Topics report on issues such as comparison of sampling methods and vapor/solid distributions of HAPs. Volume 2: Appendices include quality assurance/quality control results, uncertainty analysis for emission factors, and data sheets. This study involved measurements of a variety of substances in solid, liquid, and gaseous samples from input, output, and process streams at the Innovative Clean Coal Technology Demonstration (ICCT) of the Wet Sulfuric Acid-Selective Catalytic Reduction (SNOX) process. The SNOX demonstration is being conducted at Ohio Edison`s Niles Boiler No. 2 which uses cyclone burners to burn bituminous coal. A 35 megawatt slipstream of flue gas from the boiler is used to demonstrate SNOX. The substances measured at the SNOX process were the following: 1. Five major and 16 trace elements, including mercury, chromium, cadmium, lead, selenium, arsenic, beryllium, and nickel; 2. Acids and corresponding anions (HCl, HF, chloride, fluoride, phosphate, sulfate); 3. Ammonia and cyanide; 4. Elemental carbon; 5. Radionuclides; 6. Volatile organic compounds (VOC); 7.

    Within the last few years, new technology has come to play an important part in our professional and private daily environment. Healthcare has not escaped this progressive mutation with computers reaching the bedside. Clinical research has also shown growing interest in these new tools available to the clinical investigator, the patient, as well as to specialist departments for diagnosis and follow-up of patients, and to the different professions in clinical research. If the use of new technology seems to make life easier, by centralizing data or by simplifying data-sharing between different teams, it is still a matter of private data which must remain reliable, confidential and secure, whether it is being used in ordinary healthcare or in academic or industrial research. The aim of the round table was to estimate the impact of new information technology applied to clinical trials (including source data-medical records) and to human and drug research. First, an inventory was made of the development of these new technologies in the healthcare system. The second point developed was identification of expected benefits in order to issue guidelines for their good use and hazard warnings in clinical trials. Finally, the impact of these new technologies on the investigator as well as the project manager was analysed.

    The Graduate K-12 (GK12) program has been developed by NSF to support the national effort to advance scientific knowledge through educational partnerships. This paper highlights research conducted during the 2006-2007 school year with the Texas A&M University GK12 project. Two elementary schools with very high numbers of at risk students - those who are poor, speak English as their second language, and have a history of failing state-mandated tests were identified to be the field site for the GK12 project. In these two, high-minority (97% and 40% African American and Hispanic) schools, 80% and 56% of the children have been identified by the state as at risk; 94% and 52% are classified as economically disadvantaged; and 46% and 2% are limited English proficient, respectively. In the past year, 30% and 73% of fifth grade students in these schools passed the science portion of the Texas Assessment of Knowledge and Skills (TAKS) test. Data collected during a three- week period where GK12 fellows taught the fifth graders Earth science-related topics is presented. During the implementation, students were engaged in technology-, inquiry-, and game-based activities. Students were divided into low-, medium-, and high-abilities in one school, and regular and bilingual groups in the other.

    Pregnancy rates after frozen embryo transfer (FET) have improved in recent years and are now approaching or even exceeding those obtained after fresh embryo transfer. This is partly due to improved laboratory techniques, but may also be caused by a more physiological hormonal and endometrial environment in FET cycles. Furthermore, the risk of ovarian hyperstimulation syndrome is practically eliminated in segmentation cycles followed by FET and the use of natural cycles in FETs may be beneficial for the postimplantational conditions of fetal development. However, a freeze-all strategy is not yet implemented as standard care due to limitations of large randomised trials showing a benefit of such a strategy. Thus, there is a need to test the concept against standard care in a randomised controlled design. This study aims to compare ongoing pregnancy and live birth rates between a freeze-all strategy with gonadotropin-releasing hormone (GnRH) agonist triggering versus human chorionic gonadotropin (hCG) trigger and fresh embryo transfer in a multicentre randomised controlled trial. Multicentre randomised, controlled, double-blinded trial of women undergoing assisted reproductive technology treatment including 424 normo-ovulatory women aged 18-39 years from Denmark and Sweden. Participants will be randomised (1:1) to either (1) GnRH agonist trigger and single vitrified-warmed blastocyst transfer in a subsequent hCG triggered natural menstrual cycle or (2) hCG trigger and single blastocyst transfer in the fresh (stimulated) cycle. The primary endpoint is to compare ongoing pregnancy rates per randomised patient in the two treatment groups after the first single blastocyst transfer. The study will be performed in accordance with the ethical principles in the Helsinki Declaration. The study is approved by the Scientific Ethical Committees in Denmark and Sweden. The results of the study will be publically disseminated. NCT02746562; Pre-results. © Article author(s) (or their

  9. Syntactic Topic Models

    CERN Document Server

    Boyd-Graber, Jordan

    2010-01-01

    The syntactic topic model (STM) is a Bayesian nonparametric model of language that discovers latent distributions of words (topics) that are both semantically and syntactically coherent. The STM models dependency parsed corpora where sentences are grouped into documents. It assumes that each word is drawn from a latent topic chosen by combining document-level features and the local syntactic context. Each document has a distribution over latent topics, as in topic models, which provides the semantic consistency. Each element in the dependency parse tree also has a distribution over the topics of its children, as in latent-state syntax models, which provides the syntactic consistency. These distributions are convolved so that the topic of each word is likely under both its document and syntactic context. We derive a fast posterior inference algorithm based on variational methods. We report qualitative and quantitative studies on both synthetic data and hand-parsed documents. We show that the STM is a more pred...

  10. Syntacticized topics in Kurmuk

    DEFF Research Database (Denmark)

    Andersen, Torben

    2015-01-01

    This article argues that Kurmuk, a little-described Western Nilotic language, is characterized by a syntacticized topic whose grammatical relation is variable. In this language, declarative clauses have as topic an obligatory preverbal NP which is either a subject, an object or an adjunct....... The grammatical relation of the topic is expressed by a voice-like inflection of the verb, here called orientation. While subject-orientation is morphologically unmarked, object-oriented and adjunct-oriented verbs are marked by a subject suffix or by a suffix indicating that the topic is not subject, and adjunct......-orientation differs from object-orientation by a marked tone pattern. Topic choice largely reflects information structure by indicating topic continuity. The topic also plays a crucial role in relative clauses and in clauses with contrastive constituent focus, in that objects and adjuncts can only be relativized...

  11. Topics in orbit equivalence

    CERN Document Server

    Kechris, Alexander S

    2004-01-01

    This volume provides a self-contained introduction to some topics in orbit equivalence theory, a branch of ergodic theory. The first two chapters focus on hyperfiniteness and amenability. Included here are proofs of Dye's theorem that probability measure-preserving, ergodic actions of the integers are orbit equivalent and of the theorem of Connes-Feldman-Weiss identifying amenability and hyperfiniteness for non-singular equivalence relations. The presentation here is often influenced by descriptive set theory, and Borel and generic analogs of various results are discussed. The final chapter is a detailed account of Gaboriau's recent results on the theory of costs for equivalence relations and groups and its applications to proving rigidity theorems for actions of free groups.

  12. Topics in atomic physics

    CERN Document Server

    Burkhardt, Charles E

    2006-01-01

    The study of atomic physics propelled us into the quantum age in the early twentieth century and carried us into the twenty-first century with a wealth of new and, in some cases, unexplained phenomena. Topics in Atomic Physics provides a foundation for students to begin research in modern atomic physics. It can also serve as a reference because it contains material that is not easily located in other sources. A distinguishing feature is the thorough exposition of the quantum mechanical hydrogen atom using both the traditional formulation and an alternative treatment not usually found in textbooks. The alternative treatment exploits the preeminent nature of the pure Coulomb potential and places the Lenz vector operator on an equal footing with other operators corresponding to classically conserved quantities. A number of difficult to find proofs and derivations are included as is development of operator formalism that permits facile solution of the Stark effect in hydrogen. Discussion of the classical hydrogen...

    Rashdan, Ahmad Al; Oxstrand, Johanna; Agarwal, Vivek

    2017-02-01

    As part of the ongoing efforts at the U.S. Department of Energy’s Light Water Reactor Sustainability Program, Idaho National Laboratory is conducting several pilot projects in collaboration with the nuclear industry to improve the reliability, safety, and economics of the nuclear power industry, especially as the nuclear power plants extend their operating licenses to 80 years. One of these pilot projects is the automated work package (AWP) pilot project. An AWP is an electronic intelligent and interactive work package. It uses plant condition, resources status, and user progress to adaptively drive the work process in a manner that increases efficiency while reducing human error. To achieve this mission, the AWP acquires information from various systems of a nuclear power plant’s and incorporates several advanced instrumentation and control technologies along with modern human factors techniques. With the current rapid technological advancement, it is possible to envision several available or soon-to-be-available capabilities that can play a significant role in improving the work package process. As a pilot project, the AWP project develops a prototype of an expanding set of capabilities and evaluates them in an industrial environment. While some of the proposed capabilities are based on using technological advances in other applications, others are conceptual; thus, require significant research and development to be applicable in an AWP. The scope of this paper is to introduce a set of envisioned capabilities, their need for the industry, and the industry difficulties they resolve.

  15. Topic Information Collection based on the Hidden Markov Model

    2013-02-01

    Full Text Available Specific-subject oriented information collection is one of the key technologies of vertical search engines, which directly affects the speed and relevance of search results. The topic information collection algorithm is widely used for its accuracy. The Hidden Markov Model (HMM is used to learn and judge the relevance between the Uniform Resource Locator (URL and the topic information. The Rocchio method is used to construct the prototype vectors relevant to the topic information, and the HMM is used to learn the preferred browsing paths. The concept maps including the semantics of the webpage are constructed and the web's link structures can be decided. The validity of the algorithm is proved by the experiment at last. Comparing with the Best-First algorithm, this algorithm can get more information pages and has higher precision ratio.

    Wright, C.A.; Weijers, L.; Minner, W.A.

    1996-06-01

    Pinnacle Technologies successfully deployed AST to numerous engineers from Unocal. Unocal estimated an 11% reduction in completion costs after implementing AST on their hydraulic fracture treatments in the Rincon Unit, New Mexico, resulting in a total cost savings of $850,000 on 25 wells. Despite the poorer geology of the newly completed wells, well productivity was equivalent to the older wells with `conventional` fracture treatment designs. Pressure build-up tests also confirmed the improved fracture treatment results: propped fractures of AST-treatments appeared at least twice as long as fractures from conventional treatments, even though completion costs have been reduced.

  17. [Topical therapy of rosacea].

    Science.gov (United States)

    Schöfer, H

    2013-07-01

    Metronidazole and azelaic acid are the only topical medications approved for rosacea. All other topical treatments for rosacea and its special forms are used off-label. Topical steroids are not indicated in rosacea, because of their side effects (induction of steroid rosacea, high risk of facial skin atrophy, and high risk of rebound after cessation of therapy). Topical as well as systemic steroids are allowed only as initial and short term therapy for acute forms of rosacea (e.g. rosacea fulminans). Papular and pustular rosacea is the major indication for topical therapy. Sebaceous gland and connective tissue hyperplasia in glandular-hypertrophic rosacea as well as erythema in erythematous rosacea do not respond well to topical measures. A new active substance, the alpha-2-adrenoreceptor agonist brimonidine, will be approved soon for the topical treatment of erythema in rosacea. All severe forms of rosacea should initially be treated with a combination of topical and systemic agents. After improvement of the clinical symptoms, topical treatment alone is usually adequate to maintain the control.

    2016-12-01

    This paper presents a visual analytics approach to analyzing a full picture of relevant topics discussed in multiple sources, such as news, blogs, or micro-blogs. The full picture consists of a number of common topics covered by multiple sources, as well as distinctive topics from each source. Our approach models each textual corpus as a topic graph. These graphs are then matched using a consistent graph matching method. Next, we develop a level-of-detail (LOD) visualization that balances both readability and stability. Accordingly, the resulting visualization enhances the ability of users to understand and analyze the matched graph from multiple perspectives. By incorporating metric learning and feature selection into the graph matching algorithm, we allow users to interactively modify the graph matching result based on their information needs. We have applied our approach to various types of data, including news articles, tweets, and blog data. Quantitative evaluation and real-world case studies demonstrate the promise of our approach, especially in support of examining a topic-graph-based full picture at different levels of detail.

    1994-06-01

    The Secondary Natural Gas Recovery (SGR): Targeted Technology Applications for Infield Reserve Growth is a joint venture research project sponsored by the Gas Research Institute (GRI), the US Department of Energy (DOE), the State of Texas through the Bureau of Economic Geology at The University of Texas at Austin, with the cofunding and cooperation of the natural gas industry. The SGR project is a field-based program using an integrated multidisciplinary approach that integrates geology, geophysics, engineering, and petrophysics. A major objective of this research project is to develop, test, and verify those technologies and methodologies that have near- to mid-term potential for maximizing recovery of gas from conventional reservoirs in known fields. Natural gas reservoirs in the Gulf Coast Basin are targeted as data-rich, field-based models for evaluating infield development. The SGR research program focuses on sandstone-dominated reservoirs in fluvial-deltaic plays within the onshore Gulf Coast Basin of Texas. The primary project research objectives are: To establish how depositional and diagenetic heterogeneities cause, even in reservoirs of conventional permeability, reservoir compartmentalization and hence incomplete recovery of natural gas. To document examples of reserve growth occurrence and potential from fluvial and deltaic sandstones of the Texas Gulf Coast Basin as a natural laboratory for developing concepts and testing applications. To demonstrate how the integration of geology, reservoir engineering, geophysics, and well log analysis/petrophysics leads to strategic recompletion and well placement opportunities for reserve growth in mature fields.

  1. Recent Advances In Topical Therapy In Dermatology

    Directory of Open Access Journals (Sweden)

    Mohan Thappa Devinder

    2003-01-01

    Full Text Available With changing times various newer topical agents are introduced in the field of dermatology. Tacrolimus and pimecrolimus are immunisuppressants, which are effective topically and are tried in the management of atopic dermatitis as well as other disorders including allergic contact dermatitis, atrophic lichen planus, pyoderma gangrenosum. Imiquimod, an immune response modifier, is presently in use for genital warts but has potentials as anti- tumour agent and in various other dermatological conditions when used topically. Tazarotene is a newer addition to the list of topical reginoids, which is effective in psoriasis and has better effect in combination with calcipotriene, phototherapy and topical costicosteroids. Tazarotene and adapelene are also effective in inflammatory acne. Calcipotriol, a vitamin D analogue has been introduced as a topical agent in the treatment of psoriasis. Steroid components are also developed recently which will be devoid of the side effects but having adequate anti-inflammatory effect. Topical photodynamic therapy has also a wide range of use in dermatology. Newer topical agents including cidofovir, capsaicin, topical sensitizers, topical antifungal agents for onychomycosis are also of use in clinical practice. Other promising developments include skin substitutes and growth factors for wound care.

  2. DEVELOPMENT OF A NOVEL GAS PRESSURIZED STRIPPING (GPS)-BASED TECHNOLOGY FOR CO2 CAPTURE FROM POST-COMBUSTION FLUE GASES Topical Report: Techno-Economic Analysis of GPS-based Technology for CO2 Capture

    Energy Technology Data Exchange (ETDEWEB)

    Chen, Shiaoguo

    2015-09-30

    This topical report presents the techno-economic analysis, conducted by Carbon Capture Scientific, LLC (CCS) and Nexant, for a nominal 550 MWe supercritical pulverized coal (PC) power plant utilizing CCS patented Gas Pressurized Stripping (GPS) technology for post-combustion carbon capture (PCC). Illinois No. 6 coal is used as fuel. Because of the difference in performance between the GPS-based PCC and the MEA-based CO2 absorption technology, the net power output of this plant is not exactly 550 MWe. DOE/NETL Case 11 supercritical PC plant without CO2 capture and Case 12 supercritical PC plant with benchmark MEA-based CO2 capture are chosen as references. In order to include CO2 compression process for the baseline case, CCS independently evaluated the generic 30 wt% MEA-based PCC process together with the CO2 compression section. The net power produced in the supercritical PC plant with GPS-based PCC is 647 MW, greater than the MEA-based design. The levelized cost of electricity (LCOE) over a 20-year period is adopted to assess techno-economic performance. The LCOE for the supercritical PC plant with GPS-based PCC, not considering CO2 transport, storage and monitoring (TS&M), is 97.4 mills/kWh, or 152% of the Case 11 supercritical PC plant without CO2 capture, equivalent to $39.6/tonne for the cost of CO2 capture. GPS-based PCC is also significantly superior to the generic MEA-based PCC with CO2 compression section, whose LCOE is as high as 109.6 mills/kWh.

    The Accellera Universal Verification Methodology (UVM) standard is architected to scale, but verification is growing and in more than just the digital design dimension. It is growing in the SoC dimension to include low-power and mixed-signal and the system integration dimension to include multi-language support and acceleration. These items and others all contribute to the quality of the SOC so the Metric-Driven Verification (MDV) methodology is needed to unify it all into a coherent verification plan. This book is for verification engineers and managers familiar with the UVM and the benefits it brings to digital verification but who also need to tackle specialized tasks. It is also written for the SoC project manager that is tasked with building an efficient worldwide team. While the task continues to become more complex, Advanced Verification Topics describes methodologies outside of the Accellera UVM standard, but that build on it, to provide a way for SoC teams to stay productive and profitable.

    1997-11-01

    Contamination in low-permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, and pump and treat rather ineffective when applied to low-permeability soils present at many contaminated sites. The technology is an integrated in-situ treatment in which established geotechnical methods are used to install degradation zones directly in the contaminated soil, and electro-osmosis is utilized to move the contaminants back and forth through those zones until the treatment is complete. The present Topical Report for Task {number_sign}3.2 summarizes the modeling and dechlorination research conducted by General Electric Research and Development.

    Chen, K

    1995-01-01

    This paper proposes a corpus-based language model for topic identification. We analyze the association of noun-noun and noun-verb pairs in LOB Corpus. The word association norms are based on three factors: 1) word importance, 2) pair co-occurrence, and 3) distance. They are trained on the paragraph and sentence levels for noun-noun and noun-verb pairs, respectively. Under the topic coherence postulation, the nouns that have the strongest connectivities with the other nouns and verbs in the discourse form the preferred topic set. The collocational semantics then is used to identify the topics from paragraphs and to discuss the topic shift phenomenon among paragraphs.

    The purpose of this study was to identify training topics and distance education technologies preferred by U.S. Fish and Wildlife Service employees. This study was conducted on behalf of the National Conservation Training Center to support their distance education strategy planning and implementation. When selecting survey recipients, we focused on employees in positions involving conservation and environmental education and outreach programming. We conducted the study in two phases. First, we surveyed 72 employees to identify useful training topics. The response rate was 61 percent; respondents were from all regions and included supervisors and nonsupervisors. Five topics for training were identified: creating and maintaining partnerships (partnerships), technology, program planning and development (program planning), outreach methods to engage the community (outreach methods), and evaluation methods. In the second phase, we surveyed 1,488 employees to assess preferences for training among the five topics identified in the first survey and preferences among six distance education technologies: satellite television, video conferencing, audio conferencing, computer mediated training, written resources, and audio resources. Two types of instructor-led training were included on the survey to compare to the technology options. Respondents were asked what types of information, such as basic facts or problem solving skills, were needed for each of the five topics. The adjusted response rate was 64 percent; respondents were from all regions and included supervisors and nonsupervisors. The results indicated clear preferences among respondents for certain training topics and technologies. All five training topics were valued, but the topics of partnerships and technology were given equal value and were valued more than the other three topics. Respondents indicated a desire for training on the topics of partnerships, technology, program planning, and outreach methods. For

    Full Text Available Water shortage and water pollution are important factors restricting sustainable social and economic development. As a typical coal resource-exhausted city and a node city of the South-to-North Water Transfer East Route Project in China, Zaozhuang City’s water resources management faces multiple constraints such as transformation of economic development, restriction of groundwater exploitation, and improvement of water environment. In this paper, we develop a linear optimization model by input–output analysis to study water resources management with the introduction of three advanced sewage treatment technologies for pollutant treatment and reclaimed water production. The simulation results showed that from 2014 to 2020, Zaozhuang City will realize an annual GDP growth rate of 7.1% with an annual chemical oxygen demand (COD emissions reduction rate of 5.5%. The proportion of primary industry, secondary industry, and tertiary industry would be adjusted to 5.6%, 40.8%, and 53.6%, respectively. The amount of reclaimed water supply could be increased by 91% and groundwater supply could be decreased by 6%. Based on the simulation, this model proposes a scientific reference on water resources management policies, including water environment control, water supply plan, and financial subsidy, to realize the sustainable development of economy and water resources usage.

    2009-09-01

    This topical issue of Physica Scripta collects selected peer-reviewed contributions based on invited and contributed talks and posters presented at the 15th Central European Workshop on Quantum Optics (CEWQO) which took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu). On behalf of the whole community took place in Belgrade 29 May-3 June 2008 (http://cewqo08.phy.bg.ac.yu, cewqo08.phy.bg.ac.yu). On behalf of the whole community of the workshop, we thank the referees for their careful reading and useful suggestions which helped to improve all of the submitted papers. A brief description of CEWQO The Central European Workshop on Quantum Optics is a series of conferences started informally in Budapest in 1992. Sometimes small events transform into important conferences, as in the case of CEWQO. Professor Jozsef Janszky, from the Research Institute of Solid State Physics and Optics, is the founder of this series. Margarita Man'ko obtained the following information from Jozsef Janszky during her visit to Budapest, within the framework of cooperation between the Russian and Hungarian Academies of Sciences in 2005. He organized a small workshop on quantum optics in Budapest in 1992 with John Klauder as a main speaker. Then, bearing in mind that a year before Janszky himself was invited by Vladimir Buzek to give a seminar on the same topic in Bratislava, he decided to assign the name 'Central European Workshop on Quantum Optics', considering the seminar in Bratislava to be the first workshop and the one in Budapest the second. The third formal workshop took place in Bratislava in 1993 organized by Vladimir Buzek, then in 1994 (Budapest, by Jozsef Janszky), 1995 and 1996 (Budmerice, Slovakia, by Vladimir Buzek), 1997 (Prague, by Igor Jex), 1999 (Olomouc, Czech Republic, by Zdenek Hradil), 2000 (Balatonfüred, Hungary, by Jozsef Janszky ), 2001 (Prague, by Igor Jex), 2002 (Szeged, Hungary, by Mihaly Benedict), 2003 (Rostock,Germany, by Werner Vogel and

    Western Research Institute conducted a study to define the various parameters that need to be considered in the design and use of a downhole submersible photoionization detector (PID) probe to measure volatile organic compounds (VOCs). Detector response under various conditions, including saturated humidity environments, temperature, and analyte concentration was studied. The relative responses for several VOC analytes were measured. The partitioning of VOCs between water and air was studied as a function of analyte concentration and temperature. The Henry`s law constant governing this partitioning represents an ideal condition at infinite dilution for a particular temperature. The results show that this partitioning is not ideal. Conditions resulting in apparent, practical deviations from Henry`s law include temperature and VOC concentration. Studies with membranes show that membranes that allow passage of VOCs also allow some passage of water vapor. A membrane could play a useful role in protecting the sensor from direct contact with liquid water down hole. A porous poly(tetrafluoroethylene) (PTFE) membrane allows for a rapid passage of VOCs. The rate of diffusion to the sensor with or without a membrane might be a limiting factor for rapid measurements. Various means of mixing may need to be considered.

  19. Development of an integrated in-situ remediation technology. Topical report for task No. 12 and 13 entitled: Large scale field test of the Lasagna{trademark} process, September 26, 1994--May 25, 1996

    Contamination in low permeability soils poses a significant technical challenge to in-situ remediation efforts. Poor accessibility to the contaminants and difficulty in delivery of treatment reagents have rendered existing in-situ treatments such as bioremediation, vapor extraction, pump and treat rather ineffective when applied to low permeability soils present at many contaminated sites. This technology is an integrated in-situ treatment in which established geotechnical methods are used to instant degradation zones directly in the contaminated soil and electroosmosis is utilized to move the contaminants back and forth through those zones until the treatment is completed. This topical report summarizes the results of the field experiment conducted at the Paducah Gaseous Diffusion Plant in Paducah, KY. The test site covered 15 feet wide by 10 feet across and 15 feet deep with steel panels as electrodes and wickdrains containing granular activated carbon as treatment zone& The electrodes and treatment zones were installed utilizing innovative adaptation of existing emplacement technologies. The unit was operated for four months, flushing TCE by electroosmosis from the soil into the treatment zones where it was trapped by the activated carbon. The scale up from laboratory units to this field scale was very successful with respect to electrical parameters as weft as electroosmotic flow. Soil samples taken throughout the site before and after the test showed over 98% TCE removal, with most samples showing greater than 99% removal.

    2015-04-01

    The treatment of rosacea is challenging because several pathophysiologic processes may be involved, including neurovascular dysregulation and alterations in innate immune status. Demodex mites may play a role in the latter mechanism. Topical ivermectin is a new therapeutic modality which demonstrates antiparasitic and anti-inflammatory properties. This article reviews published evidence related to the efficacy and safety of topical ivermectin. PubMed was utilized to search for key words "topical ivermectin", "ivermectin cream" and "rosacea". Three clinical trials were found that studied topical ivermectin as a treatment option for rosacea. Ivermectin was effective, safe and well tolerated.

    Full Text Available Il a souvent été proposé que les éléments spatio-temporels en position initiale de phrase spécifient le cadre de l’événement dénoté par la proposition et ont une interprétation thématique ou topicale. Alors que les topiques spatio-temporels explicites ont souvent été étudiés, Erteschik-Schir (1997, 1999 propose l’idée que les topiques spatio-temporels, ou topiques scéniques (stage topics peuvent aussi être implicites.Dans cet article, nous offrons des arguments en faveur de la notion de topique scénique implicite. Nous montrons qu’un certain nombre de cas d’inversion nominale en français, une configuration syntaxique qui est favorisée par la présence d’un topique scénique explicite, s’expliquent par la présence d’un topique scénique implicite. Le fait que les topiques scéniques implicites interagissent avec la structure syntaxique de la même façon que les topiques scéniques explicites constitue un argument empirique en faveur de leur existence.It has often been proposed that sentence-initial spatio-temporal elements specify the frame in which the whole proposition takes place and are topical (i.e. thematic. Whereas considerable attention has been paid to explicit spatio-temporal topics, Erteschik-Shir (1997, 1999 argues that spatio-temporal topics, or stage topics, can also be implicit.In this article we provide evidence in favour of the notion of implicit stage topic. We show that a certain number of nominal inversion cases in French, a syntactic configuration which is triggered by the presence of an explicit stage topic, are explained by the presence of an implicit stage topic. The fact that implicit stage topics interact with syntactic structure the same way explicit stage topics do constitutes a strong empirical argument in favour of their existence.

    Full Text Available Impetigo is a common childhood skin infection. There are reports of increasing drug resistance to the currently used topical antibiotics including fusidic acid and mupirocin. Retapamulin is a newer topical agent of pleuromutilin class approved by the Food and Drug Administration for treatment of impetigo in children and has been recently made available in the Indian market. It has been demonstrated to have low potential for the development of antibacterial resistance and a high degree of potency against poly drug resistant Gram-positive bacteria found in skin infections including Staphylococcus aureus strains. The drug is safe owing to low systemic absorption and has only minimal side-effect of local irritation at the site of application.

    Background A panel of experts convened by the American Dental Association (ADA) Council on Scientific Affairs presents evidence-based clinical recommendations regarding professionally applied and prescription-strength, home-use topical fluoride agents for caries prevention. These recommendations are an update of the 2006 ADA recommendations regarding professionally applied topical fluoride and were developed by using a new process that includes conducting a systematic review of primary studies. Types of Studies Reviewed The authors conducted a search of MEDLINE and the Cochrane Library for clinical trials of professionally applied and prescription-strength topical fluoride agents—including mouthrinses, varnishes, gels, foams and pastes—with caries increment outcomes published in English through October 2012. Results The panel included 71 trials from 82 articles in its review and assessed the efficacy of various topical fluoride caries-preventive agents. The panel makes recommendations for further research. Practical Implications The panel recommends the following for people at risk of developing dental caries: 2.26 percent fluoride varnish or 1.23 percent fluoride (acidulated phosphate fluoride) gel, or a prescription-strength, home-use 0.5 percent fluoride gel or paste or 0.09 percent fluoride mouthrinse for patients 6 years or older. Only 2.26 percent fluoride varnish is recommended for children younger than 6 years. The strengths of the recommendations for the recommended products varied from “in favor” to “expert opinion for.” As part of the evidence-based approach to care, these clinical recommendations should be integrated with the practitioner's professional judgment and the patient's needs and preferences.

  16. Topical ketoprofen patch.

    2005-01-01

    Although oral nonsteroidal anti-inflammatory drugs (NSAIDs) are effective in the treatment of a variety of acute and chronic pain conditions, their use may be associated with serious systemic adverse effects, particularly gastrointestinal disorders. In order to minimise the incidence of systemic events related to such agents, topical NSAIDs have been developed. Topical NSAIDs, applied as gels, creams or sprays, penetrate the skin, subcutaneous fatty tissue and muscle in amounts that are sufficient to exert a therapeutic effect on peripheral and central mechanisms in the absence of high plasma concentrations. Data indicate that topical NSAIDs are effective at relieving pain in a number of acute and chronic pain indications. This review article discusses the pharmacokinetics, efficacy and tolerability of a new formulation of ketoprofen available as a topical patch. The topical patch containing ketoprofen 100mg as the active principle has been developed using a novel delivery system that dispenses therapeutic doses of the drug directly to the site of injury. Pharmacokinetic data indicate that although plasma levels of ketoprofen are higher when the drug is administered as a patch versus a gel, the total systemic bioavailability of ketoprofen 100 mg administered via a patch is no more than 10% of that reported for ketoprofen 100 mg administered orally. Because the patch facilitates ketoprofen delivery over a 24-hour period, the drug remains continually present in the tissue subjacent to the site of application. High tissue but low plasma ketoprofen concentrations mean that while tissue concentrations are high enough to exert a therapeutic effect, plasma concentrations remain low enough to not result in systemic adverse events caused by elevated serum NSAID levels. Phase III clinical trials in patients with non-articular rheumatism and traumatic painful soft tissue injuries showed that the topical ketoprofen patch was significantly more effective than placebo at

    2012-12-01

    Full Text Available The analysis of contrastive topics introduced in Büring 1997b and further developed in Büring 2003 relies on distinguishing two types of constituents that introduce alternatives: the sentence focus, which is marked by a FOC feature, and the contrastive topic, which is marked by a CT feature. A non-compositional rule of interpretation that refers to these features is used to derive a topic semantic value, a nested set of sets of propositions. This paper presents evidence for a correlation between the restrictive syntax of nested focus operators and the syntax of contrastive topics, a correlation which is unexpected under this analysis. A compositional analysis is proposed that only makes use of the flatter focus semantic values introduced by focus operators. The analysis aims at integrating insights from the original analysis while at the same time capturing the observed syntactic restrictions. http://dx.doi.org/10.3765/sp.5.8 BibTeX info

    Kodiyan, Joyson; Amber, Kyle T

    2015-09-01

    Radiation-induced skin toxicity is the most prevalent side effect of radiation therapy. Not only does it have a significant effect on patients' quality of life, but it also results in poor follow-up and early termination of radiotherapy treatment. Several skin care practices and topical applications have been studied in the field of radiodermatitis, including skin washing, topical steroids, and mechanical skin barriers. Aside from these methods, many patients turn to complementary and alternative medicine for the prevention and treatment of radiodermatitis. Many of these alternative therapies are topically applied antioxidants. While the rationale behind the use of antioxidants in treating radiodermatitis is strong, clinical studies have been far less consistent. Even in large scale randomised controlled trials, findings have been limited by the inconsistent use of topical vehicles and placebos. In this article, the authors review the role of topical antioxidants to better help the practitioner navigate through different available skin directed antioxidants.

    为了解决面向话题的搜索问题,提出一种新的面向话题的检索技术。首先分析了面向话题的搜索技术所面临的问题,然后基于数据挖掘技术提出了解决方案。利用数据挖掘技术抽取文本的多层次语义特征,形成对文本的多精度表示,抽取的特征不仅包括单个词特征也包括多词特征。建立了一个示例检索系统,实验表明利用多层次文本特征能够很好地实现面向话题的文本检索。%A novel topic-oriented text retrieval approach is proposed in this paper. In this approach,data mining techniques are used to extract multi-level semantic features from texts, generating multi-precision representation on text. Features extracted from text include both single word features and multi-word features. With this approach, more significant feature in text can be discovered and used. Extracted features are closed to the essence of texts. Experiments show that multi-level features can be used to create a topic-oriented text retrieval system.

  18. Topical management of facial burns.

    Science.gov (United States)

    Leon-Villapalos, Jorge; Jeschke, Marc G; Herndon, David N

    2008-11-01

    The face is the central point of the physical features of the human being. It transmits expressions and emotions, communicates feelings and allows for individual identity. It contains complex musculature and a pliable and unique skin envelope that reacts to the environment through a vast network of nerve endings. The face hosts vital areas that make phonation, feeding, and vision possible. Facial burns disrupt these anatomical and functional structures creating pain, deformity, swelling, and contractures that may lead to lasting physical and psychological sequelae. The management of facial burns may include operative and non-operative treatment or both, depending on the depth and extent of the burn. This paper intends to provide a review of the available options for topical management of facial burns. Topical agents will be defined as any agent applied to the surface of the skin that alters the outcome of the facial burn. Therefore, the classic concept of topical therapy will be expanded and developed within two major stages: acute and rehabilitation. Comparison of the effectiveness of the different treatments and relevant literature will be discussed.

    2014-08-01

    In the health field, technologies of care relations are in the scope of the worker-user encounter, implying intersubjectivity with the development of relationships between subjects, resulting in action. Evaluation studies synthesize knowledge produced on the consequences of using these technologies for society. This anthropological study aims to understand the perception of the elderly regarding the resolution capability and effectiveness of the acts produced in health care relationships in the context of the Family Health Strategy (ESF). The group studied consisted of 57 elderly residents in Bambui, State of Minas Gerais, Brazil. The model of signs, meanings and actions was used for collecting and analyzing data and the semi-structured interview was applied as a research technique. Elderly individuals assess resolution capability and effectiveness of the acts of care in the ESF as negative, with relation to the quality of user and professional interaction. The ESF is not effective and the desired change in the health care model has not occurred in practice. It repeats the centrality of the medical-drug-procedure model that treats the disease rather than the patient, perceiving old age as a disease and illness as being related to aging.

    2013-05-01

    This Topical Report addresses accomplishments achieved during Phase 2a of the SkyMine® Carbon Mineralization Pilot Project. The primary objectives of this project are to design, construct, and operate a system to capture CO2 from a slipstream of flue gas from a commercial coal-fired cement kiln, convert that CO2 to products having commercial value (i.e., beneficial use), show the economic viability of the CO2 capture and conversion process, and thereby advance the technology to the point of readiness for commercial scale demonstration and proliferation. The overall process is carbon negative, resulting in mineralization of CO2 that would otherwise be released into the atmosphere. The project will also substantiate market opportunities for the technology by sales of chemicals into existing markets, and identify opportunities to improve technology performance and reduce costs at the commercial scale. The project is being conducted in two phases. The primary objectives of Phase 1 were to elaborate proven SkyMine® process chemistry to commercial pilot-scale operation and complete the preliminary design for the pilot plant to be built and operated in Phase 2, complete a NEPA evaluation, and develop a comprehensive carbon life cycle analysis. The objective of the current Phase (2a) is to complete the detailed design of the pilot plant to be built in Phase 2b.

    2017-06-01

    Retrospective review. To identify the top 100 spine research topics. Recent advances in "machine learning," or computers learning without explicit instructions, have yielded broad technological advances. Topic modeling algorithms can be applied to large volumes of text to discover quantifiable themes and trends. Abstracts were extracted from the National Library of Medicine PubMed database from five prominent peer-reviewed spine journals (European Spine Journal [ESJ], The Spine Journal [SpineJ], Spine, Journal of Spinal Disorders and Techniques [JSDT], Journal of Neurosurgery: Spine [JNS]). Each abstract was entered into a latent Dirichlet allocation model specified to discover 100 topics, resulting in each abstract being assigned a probability of belonging in a topic. Topics were named using the five most frequently appearing terms within that topic. Significance of increasing ("hot") or decreasing ("cold") topic popularity over time was evaluated with simple linear regression. From 1978 to 2015, 25,805 spine-related research articles were extracted and classified into 100 topics. Top two most published topics included "clinical, surgeons, guidelines, information, care" (n = 496 articles) and "pain, back, low, treatment, chronic" (424). Top two hot trends included "disc, cervical, replacement, level, arthroplasty" (+0.05%/yr, P topics were ESJ-"operative, surgery, postoperative, underwent, preoperative"; SpineJ-"clinical, surgeons, guidelines, information, care"; Spine-"pain, back, low, treatment, chronic"; JNS- "tumor, lesions, rare, present, diagnosis"; JSDT-"cervical, anterior, plate, fusion, ACDF." Topics discovered through latent Dirichlet allocation modeling represent unbiased meaningful themes relevant to spine care. Topic dynamics can provide historical context and direction for future research for aspiring investigators and trainees interested in spine careers.

  7. Cardiovascular Complications Resulting from Topical Lidocaine Application

    Directory of Open Access Journals (Sweden)

    Feng Lin

    2008-12-01

    Full Text Available Topical lidocaine is one of the most commonly used anesthetics in the emergency department (ED. The advantages of topical anesthesia include ease of application, minimal discomfort on administration, and rapid onset of anesthesia. Systemic toxic effects after topical lidocaine application are rare. We present a case of a man aged 48 years with no history of heart disease and no evidence of bradycardia in previous electrocardiograms. The patient had sprayed lidocaine solution on the glans of his penis before sex during the 2 weeks prior to admission. Cardiovascular adverse events occurred, including chest tightness and bradycardia. After 2 hours conservative treatment at our ED, his symptoms were alleviated. He was discharged from the ED without any medication. The case suggests that detailed patient histories are necessary for accurate diagnosis and that rapid diagnosis and implementation of treatment is necessary for successful patient outcomes in cases of cardiovascular complications resulting from topical lidocaine application.

    Gibson-Howell, Joan C

    2010-01-01

    Minimal inclusion of women's health topics in dental and dental hygiene curricula may not prepare dental health care workers to provide comprehensive health care to females. The purposes of these surveys in 2001 and 2007 were to investigate United States dental hygiene school curricula regarding inclusion of women's health topics in differing degree programs (associate/certificate, baccalaureate, associate/baccalaureate) and course status (required or elective). The surveys also identified sources used to obtain women's health topics, assessed faculty continuing education participation in women's health, determined satisfaction with current curricula, questioned if change was anticipated and if so in what topics, identified where students apply their knowledge about women's health and in what ways and reported progress of dental hygiene curricula over the 6 year time period. Surveys were sent to dental hygiene program directors in 2001 (N=256) and in 2007 (N=288) asking them to complete the questionnaire. There was no statistically significant association between 2001 and 2007 survey results by degree or program setting. The educational issue, women's general health continuing education courses/topics completed by dental hygiene faculty in the past 2 years, showed a statistically significant difference during that time interval. No statistically significant difference existed between the survey years regarding topics on women's general health and oral health. Regardless of statistical significance, further details investigated percentage differences that may reveal relevant issues. These surveys establish a baseline of women's health topics included in dental hygiene curricula in order to assess knowledge of dental hygienists in practice.

  16. A study on manufacturing and quality control technology of DUPIC fuel - The characteristics and the behavior of fission products in nuclear fuels including DUPIC

    Energy Technology Data Exchange (ETDEWEB)

    Park, Kwang Hun [Kyunghee University, Seoul (Korea, Republic of)

    1995-08-01

    The scope of this research can be divided into 2 parts; the problems related to f.p.`s up to the stage of producing DUPIC fuels and the effects of f.p.`s on the performance of nuclear fuels including DUPIC. The dose rate study of fresh and spent DUPIC fuels is done. Ba-137 m is major gamma-ray source in spent nuclear fuels after five year cooling time. Cs-137 makes a secular equilibrium with Ba-137 m, and elimination of Cs induces the disappearance of Ba-137 m, in an hour. Hence, care should be taken in collecting Cs during OREOX process. A defect model of irradiated nuclear fuels for the oxygen potential based on the defect structure of pure urania is devised. This model can give the oxygen pressure of ambient gas during the sintering of DUPIC fuels. The thermal conductivity decreases with the content of f.p.`s. The temperature distribution of DUPIC fuels is calculated from the thermal conductivity. The higher operating temperature of DUPIC fuels urges us to study the fuel performance difference. O/M shift due to steep temperature gradient is expected. However, the shift is negligible if the non-stoichiometry is small. 55 refs., 22 tabs., 52 figs. (author)

    Neutron transport simulation is usually performed for criticality, power distribution, activation, scattering, dosimetry and shielding problems, among others. During the last fifteen years, innovative technological applications have been proposed (Accelerator Driven Systems, Energy Amplifiers, Spallation Neutron Sources, etc.), involving the utilization of intermediate energies (hundreds of MeV) and high-intensity (tens of mA) proton accelerators impinging in targets of high Z elements. Additionally, the use of protons, neutrons and light ions for medical applications (hadrontherapy) impose requirements on neutron dosimetry-related quantities (such as kerma factors) for biologically relevant materials, in the energy range starting at several tens of MeV. Shielding and activation related problems associated to the operation of high-energy proton accelerators, emerging space-related applications and aircrew dosimetry-related topics are also fields of intense activity requiring as accurate as possible medium- and high-energy neutron (and other hadrons) transport simulation. These applications impose specific requirements on cross-section data for structural materials, targets, actinides and biologically relevant materials. Emerging nuclear energy systems and next generation nuclear reactors also impose requirements on accurate neutron transport calculations and on cross-section data needs for structural materials, coolants and nuclear fuel materials, aiming at improved safety and detailed thermal-hydraulics and radiation damage studies. In this review paper, the state-of-the-art in the computational tools and methodologies available to perform neutron transport simulation is presented. Proton- and neutron-induced cross-section data needs and requirements are discussed. Hot topics are pinpointed, prospective views are provided and future trends identified.

  5. In-cell NMR: a topical review

    Directory of Open Access Journals (Sweden)

    Enrico Luchinat

    2017-03-01

    Full Text Available Classical structural biology approaches allow structural characterization of biological macromolecules in vitro, far from their physiological context. Nowadays, thanks to the wealth of structural data available and to technological and methodological advances, the interest of the research community is gradually shifting from pure structural determination towards the study of functional aspects of biomolecules. Therefore, a cellular structural approach is ideally needed to characterize biological molecules, such as proteins, in their native cellular environment and the functional processes that they are involved in. In-cell NMR is a new application of high-resolution nuclear magnetic resonance spectroscopy that allows structural and dynamical features of proteins and other macromolecules to be analyzed directly in living cells. Owing to its challenging nature, this methodology has shown slow, but steady, development over the past 15 years. To date, several in-cell NMR approaches have been successfully applied to both bacterial and eukaryotic cells, including several human cell lines, and important structural and functional aspects have been elucidated. In this topical review, the major advances of in-cell NMR are summarized, with a special focus on recent developments in eukaryotic and mammalian cells.

  8. Topics on electricity trade

    Energy Technology Data Exchange (ETDEWEB)

    Skytte, K.

    2001-07-01

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective.

  9. Topics on electricity trade

    The first chapter in this thesis is a survey of studies on electricity trade, which has been included in order to show how subjects in this thesis fit into this aspect of energy research. Transitions from centralised monopolies to liberalised electricity markets have been inaugurated in the northern European countries during the last decade. The backgrounds and speed of transitions differ within the countries. Where Norway liberalised its electricity market in order to stabilise the prices, EU urged a liberalisation in order to make the electricity supply industry more effective. Together with national liberalisation, the opening of the cross border trade between the countries is also urged. The first paper in this thesis describes those different liberalisation processes within northern Europe and discusses problems that may arise in a transition period for integrating the countries into a common electricity market with efficient cross-border competition. Before the liberalisation process started, the electricity generation was determined by a central load dispatch at known prices. The introduction of competition has necessitated the creation of new competitive markets, power exchanges and financial markets where generation and prices are determined by demand and supply on the markets.

  10. Topics in Banach space theory

    CERN Document Server

    Albiac, Fernando

    2016-01-01

    This text provides the reader with the necessary technical tools and background to reach the frontiers of research without the introduction of too many extraneous concepts. Detailed and accessible proofs are included, as are a variety of exercises and problems. The two new chapters in this second edition are devoted to two topics of much current interest amongst functional analysts: Greedy approximation with respect to bases in Banach spaces and nonlinear geometry of Banach spaces. This new material is intended to present these two directions of research for their intrinsic importance within Banach space theory, and to motivate graduate students interested in learning more about them. This textbook assumes only a basic knowledge of functional analysis, giving the reader a self-contained overview of the ideas and techniques in the development of modern Banach space theory. Special emphasis is placed on the study of the classical Lebesgue spaces Lp (and their sequence space analogues) and spaces of continuous f...

  11. Researching Distressing Topics

    Directory of Open Access Journals (Sweden)

    2013-05-01

    Full Text Available Qualitative researchers who explore sensitive topics may expose themselves to emotional distress. Consequently, researchers are often faced with the challenge of maintaining emotional equilibrium during the research process. However, discussion on the management of difficult emotions has occupied a peripheral place within accounts of research practice. With rare exceptions, the focus of published accounts is concentrated on the analysis of the emotional phenomena that emerge during the collection of primary research data. Hence, there is a comparative absence of a dialogue around the emotional dimensions of working with secondary data sources. This article highlights some of the complex ways in which emotions enter the research process during secondary analysis, and the ways in which we engaged with and managed emotional states such as anger, sadness, and horror. The concepts of emotional labor and emotional reflexivity are used to consider the ways in which we “worked with” and “worked on” emotion. In doing so, we draw on our collective experiences of working on two collaborative projects with ChildLine Scotland in which a secondary analysis was conducted on children’s narratives of distress, worry, abuse, and neglect.

  12. Topics in statistical mechanics

    Energy Technology Data Exchange (ETDEWEB)

    Elser, V.

    1984-05-01

    This thesis deals with four independent topics in statistical mechanics: (1) the dimer problem is solved exactly for a hexagonal lattice with general boundary using a known generating function from the theory of partitions. It is shown that the leading term in the entropy depends on the shape of the boundary; (2) continuum models of percolation and self-avoiding walks are introduced with the property that their series expansions are sums over linear graphs with intrinsic combinatorial weights and explicit dimension dependence; (3) a constrained SOS model is used to describe the edge of a simple cubic crystal. Low and high temperature results are derived as well as the detailed behavior near the crystal facet; (4) the microscopic model of the lambda-transition involving atomic permutation cycles is reexamined. In particular, a new derivation of the two-component field theory model of the critical behavior is presented. Results for a lattice model originally proposed by Kikuchi are extended with a high temperature series expansion and Monte Carlo simulation. 30 references.

  13. Superconcentration and related topics

    CERN Document Server

    Chatterjee, Sourav

    2014-01-01

    A certain curious feature of random objects, introduced by the author as “super concentration,” and two related topics, “chaos” and “multiple valleys,” are highlighted in this book. Although super concentration has established itself as a recognized feature in a number of areas of probability theory in the last twenty years (under a variety of names), the author was the first to discover and explore its connections with chaos and multiple valleys. He achieves a substantial degree of simplification and clarity in the presentation of these findings by using the spectral approach. Understanding the fluctuations of random objects is one of the major goals of probability theory and a whole subfield of probability and analysis, called concentration of measure, is devoted to understanding these fluctuations. This subfield offers a range of tools for computing upper bounds on the orders of fluctuations of very complicated random variables. Usually, concentration of measure is useful when more direct prob...

  14. Discovering health topics in social media using topic models.

    Directory of Open Access Journals (Sweden)

    Michael J Paul

    Full Text Available By aggregating self-reported health statuses across millions of users, we seek to characterize the variety of health information discussed in Twitter. We describe a topic modeling framework for discovering health topics in Twitter, a social media website. This is an exploratory approach with the goal of understanding what health topics are commonly discussed in social media. This paper describes in detail a statistical topic model created for this purpose, the Ailment Topic Aspect Model (ATAM, as well as our system for filtering general Twitter data based on health keywords and supervised classification. We show how ATAM and other topic models can automatically infer health topics in 144 million Twitter messages from 2011 to 2013. ATAM discovered 13 coherent clusters of Twitter messages, some of which correlate with seasonal influenza (r = 0.689 and allergies (r = 0.810 temporal surveillance data, as well as exercise (r =  .534 and obesity (r =  -.631 related geographic survey data in the United States. These results demonstrate that it is possible to automatically discover topics that attain statistically significant correlations with ground truth data, despite using minimal human supervision and no historical data to train the model, in contrast to prior work. Additionally, these results demonstrate that a single general-purpose model can identify many different health topics in social media.

    2012-01-01

    We propose a general method for automated word puzzle generation. Contrary to previous approaches in this novel field, the presented method does not rely on highly structured datasets obtained with serious human annotation effort: it only needs an unstructured and unannotated corpus (i.e., document collection) as input. The method builds upon two additional pillars: (i) a topic model, which induces a topic dictionary from the input corpus (examples include e.g., latent semantic analysis, group-structured dictionaries or latent Dirichlet allocation), and (ii) a semantic similarity measure of word pairs. Our method can (i) generate automatically a large number of proper word puzzles of different types, including the odd one out, choose the related word and separate the topics puzzle. (ii) It can easily create domain-specific puzzles by replacing the corpus component. (iii) It is also capable of automatically generating puzzles with parameterizable levels of difficulty suitable for, e.g., beginners or intermedia...

    2015-05-07

    Social media are widely used by the general public and by public health and health care professionals. Emerging evidence suggests engagement with public health information on social media may influence health behavior. However, the volume of data accumulating daily on Twitter and other social media is a challenge for researchers with limited resources to further examine how social media influence health. To address this challenge, we used crowdsourcing to facilitate the examination of topics associated with engagement with diabetes information on Twitter. We took a random sample of 100 tweets that included the hashtag "#diabetes" from each day during a constructed week in May and June 2014. Crowdsourcing through Amazon's Mechanical Turk platform was used to classify tweets into 9 topic categories and their senders into 3 Twitter user categories. Descriptive statistics and Tweedie regression were used to identify tweet and Twitter user characteristics associated with 2 measures of engagement, "favoriting" and "retweeting." Classification was reliable for tweet topics and Twitter user type. The most common tweet topics were medical and nonmedical resources for diabetes. Tweets that included information about diabetes-related health problems were positively and significantly associated with engagement. Tweets about diabetes prevalence, nonmedical resources for diabetes, and jokes or sarcasm about diabetes were significantly negatively associated with engagement. Crowdsourcing is a reliable, quick, and economical option for classifying tweets. Public health practitioners aiming to engage constituents around diabetes may want to focus on topics positively associated with engagement.

  2. Seven topics in functional magnetic resonance imaging.

    Bandettini, Peter A

    2009-09-01

    Functional MRI (fMRI) is a non-invasive brain imaging methodology that started in 1991 and allows human brain activation to be imaged at high resolution within only a few minutes. Because it has extremely high sensitivity, is relatively easy to implement, and can be performed on most standard clinical MRI scanners. It continues to grow at an explosive rate throughout the world. Over the years, at any given time, fMRI has been defined by only a handful of major topics that have been the focus of researchers using and developing the methodology. In this review, I attempt to take a snapshot of the field of fMRI as it is in mid-2009 by discussing the seven topics that I feel are most on the minds of fMRI researchers. The topics are, in no particular order or grouping: (1) Clinical impact, (2) Utilization of individual functional maps, (3) fMRI signal interpretation, (4) Pattern effect mapping and decoding, (5) Endogenous oscillations, (6) MRI technology, and (7) Alternative functional contrast mechanisms. Most of these topics are highly interdependent, each advancing as the others advance. While most fMRI involves applications towards clinical or neuroscience questions, all applications are fundamentally dependent on advances in basic methodology as well as advances in our understanding of the relationship between neuronal activity and fMRI signal changes. This review neglects almost completely an in-depth discussion of applications. Rather the discussions are on the methods and interpretation.

  7. Armenian media coverage of science topics

    Mkhitaryan, Marie

    2016-12-01

    The article discusses features and issues of Armenian media coverage on scientific topics and provides recommendations on how to promote scientific topics in media. The media is more interested in social or public reaction rather than in scientific information itself. Medical science has a large share of the global media coverage. It is followed by articles about environment, space, technology, physics and other areas. Armenian media mainly tends to focus on a scientific topic if at first sight it contains something revolutionary. Media primarily reviews whether that scientific study can affect the Armenian economy and only then decides to refer to it. Unfortunately, nowadays the perception of science is a little distorted in media. We can often see headlines of news where is mentioned that the scientist has made "an invention". Nowadays it is hard to see the border between a scientist and an inventor. In fact, the technological term "invention" attracts the media by making illusionary sensation and ensuring large audience. The report also addresses the "Gitamard" ("A science-man") special project started in 2016 in Mediamax that tells about scientists and their motivations.

  12. Recent advances in topical anesthesia

    Science.gov (United States)

    2016-01-01

    Topical anesthetics act on the peripheral nerves and reduce the sensation of pain at the site of application. In dentistry, they are used to control local pain caused by needling, placement of orthodontic bands, the vomiting reflex, oral mucositis, and rubber-dam clamp placement. Traditional topical anesthetics contain lidocaine or benzocaine as active ingredients and are used in the form of solutions, creams, gels, and sprays. Eutectic mixtures of local anesthesia cream, a mixture of various topical anesthetics, has been reported to be more potent than other anesthetics. Recently, new products with modified ingredients and application methods have been introduced into the market. These products may be used for mild pain during periodontal treatment, such as scaling. Dentists should be aware that topical anesthetics, although rare, might induce allergic reactions or side effects as a result of an overdose. Topical anesthetics are useful aids during dental treatment, as they reduce dental phobia, especially in children, by mitigating discomfort and pain. PMID:28879311

    2014-01-01

    Full Text Available Topics identification (TI is the process that consists in determining the main themes present in natural language documents. The current TI modeling paradigm aims at acquiring semantic information from statistic properties of large text datasets. We investigate the mental mechanisms responsible for the identification of topics in a single document given existing knowledge. Our main hypothesis is that topics are the result of accumulated neural activation of loosely organized information stored in long-term memory (LTM. We experimentally tested our hypothesis with a computational model that simulates LTM activation. The model assumes activation decay as an unavoidable phenomenon originating from the bioelectric nature of neural systems. Since decay should negatively affect the quality of topics, the model predicts the presence of short-term memory (STM to keep the focus of attention on a few words, with the expected outcome of restoring quality to a baseline level. Our experiments measured topics quality of over 300 documents with various decay rates and STM capacity. Our results showed that accumulated activation of loosely organized information was an effective mental computational commodity to identify topics. It was furthermore confirmed that rapid decay is detrimental to topics quality but that limited capacity STM restores quality to a baseline level, even exceeding it slightly.

    Viral warts are a common skin condition, which can range in severity from a minor nuisance that resolve spontaneously to a troublesome, chronic condition. Many different topical treatments are available. To evaluate the efficacy of local treatments for cutaneous non-genital warts in healthy, immunocompetent adults and children. We updated our searches of the following databases to May 2011: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 2005), EMBASE (from 2010), AMED (from 1985), LILACS (from 1982), and CINAHL (from 1981). We searched reference lists of articles and online trials registries for ongoing trials. Randomised controlled trials (RCTs) of topical treatments for cutaneous non-genital warts. Two authors independently selected trials and extracted data; a third author resolved any disagreements. We included 85 trials involving a total of 8815 randomised participants (26 new studies were included in this update). There was a wide range of different treatments and a variety of trial designs. Many of the studies were judged to be at high risk of bias in one or more areas of trial design.Trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (RR (risk ratio) 1.56, 95% CI (confidence interval) 1.20 to 2.03). Subgroup analysis for different sites, hands (RR 2.67, 95% CI 1.43 to 5.01) and feet (RR 1.29, 95% CI 1.07 to 1.55), suggested it might be more effective for hands than feet.A meta-analysis of cryotherapy versus placebo for warts at all sites favoured neither intervention nor control (RR 1.45, 95% CI 0.65 to 3.23). Subgroup analysis for different sites, hands (RR 2.63, 95% CI 0.43 to 15.94) and feet (RR 0.90, 95% CI 0.26 to 3.07), again suggested better outcomes for hands than feet. One trial showed cryotherapy to be better than both placebo and SA, but only for hand warts.There was no significant difference in cure rates between

  5. Topical peptides as cosmeceuticals

    Directory of Open Access Journals (Sweden)

    Varadraj Vasant Pai

    2017-01-01

    Full Text Available Peptides are known to have diverse biological roles, most prominently as signaling/regulatory molecules in a broad variety of physiological processes including defense, immunity, stress, growth, homeostasis and reproduction. These aspects have been used in the field of dermatology and cosmetology to produce short, stable and synthetic peptides for extracellular matrix synthesis, pigmentation, innate immunity and inflammation. The evolution of peptides over the century, which started with the discovery of penicillin, has now extended to their usage as cosmeceuticals in recent years. Cosmeceutical peptides may act as signal modulators of the extracellular matrix component, as structural peptides, carrier peptides and neurotransmitter function modulators. Transdermal delivery of peptides can be made more effective by penetration enhancers, chemical modification or encapsulation of peptides. The advantages of using peptides as cosmeceuticals include their involvement in many physiological functions of the skin, their selectivity, their lack of immunogenicity and absence of premarket regulatory requirements for their use. However, there are disadvantages: clinical evidence for efficacy is often weak, absorption may be poor due to low lipophilicity, high molecular weight and binding to other ingredients, and prices can be quite high.

  6. Topical and peripheral ketamine as an analgesic.

    Science.gov (United States)

    Sawynok, Jana

    2014-07-01

    Ketamine, in subanesthetic doses, produces systemic analgesia in chronic pain settings, an action largely attributed to block of N-methyl-D-aspartate receptors in the spinal cord and inhibition of central sensitization processes. N-methyl-D-aspartate receptors also are located peripherally on sensory afferent nerve endings, and this provided the initial impetus for exploring peripheral applications of ketamine. Ketamine also produces several other pharmacological actions (block of ion channels and receptors, modulation of transporters, anti-inflammatory effects), and while these may require higher concentrations, after topical (e.g., as gels, creams) and peripheral application (e.g., localized injections), local tissue concentrations are higher than those after systemic administration and can engage lower affinity mechanisms. Peripheral administration of ketamine by localized injection produced some alterations in sensory thresholds in experimental trials in volunteers and in complex regional pain syndrome subjects in experimental settings, but many variables were unaltered. There are several case reports of analgesia after topical application of ketamine given alone in neuropathic pain, but controlled trials have not confirmed such effects. A combination of topical ketamine with several other agents produced pain relief in case, and case series, reports with response rates of 40% to 75% in retrospective analyses. In controlled trials of neuropathic pain with topical ketamine combinations, there were improvements in some outcomes, but optimal dosing and drug combinations were not clear. Given orally (as a gargle, throat swab, localized peritonsillar injections), ketamine produced significant oral/throat analgesia in controlled trials in postoperative settings. Topical analgesics are likely more effective in particular conditions (patient factors, disease factors), and future trials of topical ketamine should include a consideration of factors that could predispose

  8. Topical treatments of skin pain: a general review with a focus on hidradenitis suppurativa with topical agents.

    Science.gov (United States)

    Scheinfeld, Noah

    2014-07-15

    Hidradenitis Supprurativa (HS) is a painful chronic follicular disease. Few papers have addressed pain control for this debilitating condition. Possible topical agents include tricyclic antidepressants, opioids, anticonvulsants, NSAIDs, NMDA receptor antagonists, local anesthetics and other agents. The first line agents for the topical treatment of the cutaneous pain of HS are diclonefac gel 1% and liposomal xylocaine 4% and 5% cream or 5% ointment. The chief advantage of topical xylocaine is that is quick acting i.e. immediate however with a limited duration of effect 1-2 hours. The use of topical ketamine, which blocks n-methyl-D-aspartate receptors in a non-competitive fashion, might be a useful tool for the treatment of HS pain. Topical doxepin, which available in a 5% commercially preparation (Zonalon®) , makes patients drowsy and is not useful for controlling the pain of HS . Doxepin is available in a 3% or 3.3% concentration (which causes less drowsiness) from compounding pharmacies and can be used in compounded analgesic preparations with positive effect. Topical doxepin is preferred over use of topical amitriptyline because topical doxepin is more effective. Nevertheless, topical amitriptyline increase of the tactile and mechanical nociceptive thresholds and can be used for topical pain control in compound mixture of analgesics . Gabapentin and pregablin can also be used compounded with other agents in topical analgesic preparations with positive topical anesthetic effect. Capsaicin is not useful for topical treatment of the pain of HS. Sometimes compounded of anesthetics medications such as ketamine 10%, bupivacaine 1%, diclofenac 3%, doxepin 3% or 3.3%, and gabapentin 6% can extend the duration of effect so that medication only needs to be used 2 or 3 times a day. Still in my experience the easiest to get and most patient requested agent is topical diclonefac 1% gel.

  1. Rosacea-like eruption due to topical pimecrolimus.

    Science.gov (United States)

    El-Heis, S; Buckley, D A

    2015-05-18

    Topical calcineurin inhibitors have been used outside their approved indications for a number of conditions, including topical steroid-induced rosacea. However, tacrolimus ointment itself has been reported to trigger rosacea in a small number of cases. We report a case of a rosacea-like eruption in a 39-year-old woman occurring after the use of pimecrolimus cream for 12 months for atopic dermatitis. Withdrawal of pimecrolimus combined with treatment with oral lymecycline, topical metronidazole, and an emollient resulted in resolution of the eruption. There have been 5 previously reported cases of a topical pimecrolimus-induced rosacea-like eruption suggesting that this rare side-effect may be a class effect of all topical calcineurin inhibitors. Dermatologists prescribing these drugs should be aware of this uncommon complication and may wish to warn patients of its occurrence as a potential side-effect when using topical calcineurin inhibitors in facial skin in adults.

    2003-06-01

    Full Text Available Knowledge management (KM has received much attention from both academics and practitioners in the past few years. Following the KM trend, many organizations have built their own knowledge repositories or data warehouses. However, information or knowledge is still scattered everywhere without being properly managed. The rapid growth of the Internet accelerates the creation of unstructured and unclassified information and causes the explosion of information overload. The effort of browsing information through general-purpose search engines turns out to be tedious and painstaking. Hence, an effective technology to solve this information retrieval problem is much needed. The purpose of this research is to explore the application of text mining technique in organizing knowledge stored in unstructured natural language text documents. Major components of text mining techniques required for topic map in particular will be presented in detail.Two sets of unstructured documents are utilized to demonstrate the usage of SOM for topic categorization. The first set of documents is a collection of speeches given by Y.C. Wang, Chairman of the Taiwan Plastics Group, and the other is the collection of all laws and regulations related to securities and future markets in Taiwan. We also try to apply text mining to these two sets of documents to generate their respective topic maps, thus revealing the differences between organizing explicit and tacit knowledge as well as the difficulties associated with tacit knowledge.[Article content in Chinese

    Full Text Available Introduction Understanding of fluid shifts and recognition of the importance of early and appropriate fluid replacement therapy have significantly reduced mortality in the early post burn period. After the bum patient successfully passes the resuscitation period, the burn wound represents the greatest threat to survival. History Since the dawn of civilization, man has been trying to find an agent which would help burn wounds heal, and at the same time, not harm general condition of the injured. It was not until the XX century, after the discovery of antibiotics, when this condition was fulfilled. In 1968, combining silver and sulfadiazine, fox made silver-sulfadiazine, which is a 1% hydro-soluble cream and a superior agent in topical treatment of burns today. Current topical agents None of the topical antimicrobial agents available today, alone or combined, have the characteristics of ideal prophylactic agents, but they eliminate colonization of burn wound, and invasive infections are infrequent. With an excellent spectrum of activity, low toxicity, and ease of application with minimal pain, silver-sulfadiazine is still the most frequently used topical agent. Conclusion The incidence of invasive infections and overall mortality have been significantly reduced after introduction of topical burn wound antimicrobial agents into practice. In most burn patients the drug of choice for prophylaxis is silver sulfadiazine. Other agents may be useful in certain clinical situations.

    2014-01-01

    Full Text Available Corticosteroids, one of the most widely prescribed topical drugs, have been used for about six decades till date. However, rampant misuse and abuse down the years has given the drug a bad name. Topical steroid abuse may lead to two major problems which lie at the opposing ends of the psychosomatic spectrum. Topical steroid addiction, a phenomenon that came to be recognized about a decade after the introduction of the molecule is manifested as psychological distress and rebound phenomenon on stoppage of the drug. The rebound phenomenon, which can affect various parts of the body particularly the face and the genitalia has been reported by various names in the literature. TC phobia which lies at the opposite end of the psychiatric spectrum of steroid abuse has been reported particularly among parents of atopic children. Management of both conditions is difficult and frustrating. Psychological counseling and support can be of immense help in both the conditions.

    2014-10-01

    Primary focal hyperhidrosis affects 3% of the US population; about the same number as psoriasis. More than half of these patients have primary focal axillary hyperhidrosis: sweating that is beyond what is anticipated or necessary for thermoregulation. Most topical therapies are based on aluminum salts, which work by a chemical reaction that forms plugs in the eccrine sweat ducts. Topical anticholinergics may also be used. Instruction on proper methods and timing of antiperspirants enhances effect and may be effective alone or in combination with other treatments in patients with hyperhidrosis.

    A content analysis of all (N = 604) published articles in the Community Mental Health Journal from 1965 through 1977 was performed (a) to provide a cross-sectional view of the community mental health field, and (b) to identify topic trends over time. Sixty-one content categories were used to classify topic areas. Results revealed major and growing emphases on organizing for the delivery and measuring of the effects of mental health service systems. Topics found to be increasing in relative frequency over time included training, measurement and research methodology, and intervention; those decreasing included planning and needs assessment, therapy, and suicide. Topic areas were compared with key characteristics of the field. Topic trends were interpreted in terms of open systems theory.

  5. Advanced sulfur control concepts in hot-gas desulfurization technology: Phase 2. Exploratory studies on the direct production of elemental sulfur during the regeneration of high temperature desulfurization sorbents. Topical report

    The topical report describes the results of Phase 2 research to determine the feasibility of the direct production of elemental sulfur during the regeneration of high temperature desulfurization sorbents. Many of the contaminants present in coal emerge from the gasification process in the product gas. Much effort has gone into the development of high temperature metal oxide sorbents for removal of H{sub 2}S from coal gas. The oxides of zinc, iron, manganese, and others have been studied. In order for high temperature desulfurization to be economical it is necessary that the sorbents be regenerated to permit multicycle operation. Current methods of sorbent regeneration involve oxidation of the metal sulfide to reform the metal oxide and free the sulfur as SO{sub 2}. An alternate regeneration process in which the sulfur is liberated in elemental form is desired. Elemental sulfur, which is the typical feed to sulfuric acid plants, may be easily separated, stored, and transported. Although research to convert SO{sub 2} produced during sorbent regeneration to elemental sulfur is on-going, additional processing steps are required and the overall process will be more complex. Clearly, the direct production of elemental sulfur is preferred. Desulfurization utilizing a cerium oxide based sorbent is discussed.

    1992-04-20

    This Topical Report No. 2 is an interim report on the Duct Injection Test Facility being operated for the Department of Energy at Beverly, Ohio. Either dry calcium hydroxide or an aqueous slurry of calcium hydroxide (prepared by slaking quicklime) is injected into a slipstream of flue gas to achieve partial removal of SO{sub 2} from a coal-burning power station. Water injected with the slurry or injected separately from the dry sorbents cools the flue gas and increases the water vapor content of the gas. The addition of water, either in the slurry or in a separate spray, makes the extent of reaction between the sorbent and the SO{sub 2} more complete; the presumption is that water is effective in the liquid state, when it is able to wet the sorbent particles physically, and not especially effective in the vapor state. An electrostatic precipitator collects the combination of suspended solids (fly ash from the boiler and sorbent from the duct injection process). All of the operations are being carried out on the scale of approximately 50,000 acfm of flue gas.

    To analyze the analgesic effect of remifentanil, side effects and complications in topical strabismus surgery. To study the results of strabismus surgery with this type of anesthesia. Retrospective descriptive study. We included 39 patients undergoing strabismus surgery with topical anesthesia and analgesia-based sedation with remifentanil. The data of the anesthetic and surgical technique, surgical results and stability of the deviation angle were analyzed. Thirty nine patients (54% women) were included, the average age was 37,4years old. The mean follow-up was 24,5months. The preoperative diagnoses were exotropia (21 patients), esotropia (12), paresis strabismus (4) and Duane's Syndrome (2). 15% patients had preoperative diplopia and 13 had received previous treatments. The dose range of remifentanil used was 0.05 to 0.2μg/kg/min. The side effects presented were 2 cases of vomit and one of bad collaboration during the intraoperative adjustment, one of the patient reported pain and one case of thoracic rigidity was reported. 79% of the patients obtained a good surgical result and 82% reported being satisfied with the results. The reintervention rate was 5%. Analgesia-based sedation with remifentanil is an useful complement to topical strabismus surgery because it reduces pain during surgery and allows the patient to collaborate during intraoperative adjustment due to its pharmacokinetic characteristics.

  9. Topical Nano and Microemulsions for Skin Delivery

    Directory of Open Access Journals (Sweden)

    Christofori M. R. R. Nastiti

    2017-09-01

    Full Text Available Nanosystems such as microemulsions (ME and nanoemulsions (NE offer considerable opportunities for targeted drug delivery to and via the skin. ME and NE are stable colloidal systems composed of oil and water, stabilised by a mixture of surfactants and cosurfactants, that have received particular interest as topical skin delivery systems. There is considerable scope to manipulate the formulation components and characteristics to achieve optimal bioavailability and minimal skin irritancy. This includes the incorporation of established chemical penetration enhancers to fluidize the stratum corneum lipid bilayers, thus reducing the primary skin barrier and increasing permeation. This review discusses nanosystems with utility in skin delivery and focuses on the composition and characterization of ME and NE for topical and transdermal delivery. The mechanism of skin delivery across the stratum corneum and via hair follicles is reviewed with particular focus on the influence of formulation.

    Pressure ulcers are common in clinical practice and pose a significant health problem worldwide. Apart from causing suffering to patients, they also result in longer hospital stays and increase the cost of health care. A variety of methods are used for treating pressure ulcers, including pressure relief, patient repositioning, biophysical strategies, nutritional supplementation, debridement, topical negative pressure, and local treatments including dressings, ointments and creams such as bacitracin, silver sulphadiazine, neomycin, and phenytoin. Phenytoin is a drug more commonly used in the treatment of epilepsy, but may play an important role in accelerating ulcer healing. To assess the effects of topical phenytoin on the rate of healing of pressure ulcers of any grade, in any care setting. In September 2016, we searched the following electronic databases to identify relevant randomized clinical trials: the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL; the Cochrane Library); Ovid MEDLINE; Ovid Embase; and EBSCO CINAHL Plus. We handsearched conference proceedings from the European Pressure Ulcer Advisory Panel, European Wound Management Association and the Tissue Viability Society for all available years. We searched the references of the retrieved trials to identify further relevant trials. We also searched clinical trials registries to identify ongoing and unpublished studies. There were no restrictions with respect to language, date of publication or study setting. We included all randomized controlled trials (RCTs) addressing the effects (both benefits and harms) of topical phenytoin on the healing of pressure ulcers of any grade compared with placebo or alternative treatments or no therapy, irrespective of blinding, language, and publication status. Two review authors independently selected studies, extracted information on participants, interventions, methods and results and assessed risk of bias using

  14. The pharmacology of topical analgesics.

    Barkin, Robert L

    2013-07-01

    Pain management of patients continues to pose challenges to clinicians. Given the multiple dimensions of pain--whether acute or chronic, mild, moderate, or severe, nociceptive or neuropathic--a multimodal approach may be needed. Fortunately, clinicians have an array of nonpharmacologic and pharmacologic treatment choices; however, each modality must be chosen carefully, because some often used oral agents are associated with safety and tolerability issues that restrict their use in certain patients. In particular, orally administered nonsteroidal antiinflammatory drugs, opioids, antidepressants, and anticonvulsants are known to cause systemic adverse effects in some patients. To address this problem, a number of topical therapies in various therapeutic classes have been developed to reduce systemic exposure and minimize the risks of patients developing adverse events. For example, topical nonsteroidal anti-inflammatory drug formulations produce a site-specific effect (ie, cyclo-oxygenase inhibition) while decreasing the systemic exposure that may lead to undesired effects in patients. Similarly, derivatives of acetylsalicylic acid (ie, salicylates) are used in topical analgesic formulations that do not significantly enter the patient's systemic circulation. Salicylates, along with capsaicin, menthol, and camphor, compose the counterirritant class of topical analgesics, which produce analgesia by activating and then desensitizing epidermal nociceptors. Additionally, patches and creams that contain the local anesthetic lidocaine, alone or co-formulated with other local anesthetics, are also used to manage patients with select acute and chronic pain states. Perhaps the most common topical analgesic modality is the cautious application of cutaneous cold and heat. Such treatments may decrease pain not by reaching the target tissue through systemic distribution, but by acting more directly on the affected tissue. Despite the tolerability benefits associated with avoiding

  15. Topics in linear optical quantum computation

    Science.gov (United States)

    Glancy, Scott Charles

    This thesis covers several topics in optical quantum computation. A quantum computer is a computational device which is able to manipulate information by performing unitary operations on some physical system whose state can be described as a vector (or mixture of vectors) in a Hilbert space. The basic unit of information, called the qubit, is considered to be a system with two orthogonal states, which are assigned logical values of 0 and 1. Photons make excellent candidates to serve as qubits. They have little interactions with the environment. Many operations can be performed using very simple linear optical devices such as beam splitters and phase shifters. Photons can easily be processed through circuit-like networks. Operations can be performed in very short times. Photons are ideally suited for the long-distance communication of quantum information. The great difficulty in constructing an optical quantum computer is that photons naturally interact weakly with one another. This thesis first gives a brief review of two early approaches to optical quantum computation. It will describe how any discrete unitary operation can be performed using a single photon and a network of beam splitters, and how the Kerr effect can be used to construct a two photon logic gate. Second, this work provides a thorough introduction to the linear optical quantum computer developed by Knill, Laflamme, and Milburn. It then presents this author's results on the reliability of this scheme when implemented using imperfect photon detectors. This author finds that quantum computers of this sort cannot be built using current technology. Third, this dissertation describes a method for constructing a linear optical quantum computer using nearly orthogonal coherent states of light as the qubits. It shows how a universal set of logic operations can be performed, including calculations of the fidelity with which these operations may be accomplished. It discusses methods for reducing and

    Full Text Available Over the past 30 years, policy makers and professionals who provide services to older adults with chronic conditions and impairments have placed greater emphasis on conceptualizing aging in place as an attainable and worthwhile goal. Little is known, however, of the changes in how this concept has evolved in aging research. To track trends in aging in place, we examined scholarly articles published from 1980 to 2010 that included the concept in eleven academic gerontology journals. We report an increase in the absolute number and proportion of aging-in-place manuscripts published during this period, with marked growth in the 2000s. Topics related to the environment and services were the most commonly examined during 2000–2010 (35% and 31%, resp., with a substantial increase in manuscripts pertaining to technology and health/functioning. This underscores the increase in diversity of topics that surround the concept of aging-in-place literature in gerontological research.

    Brachial plexus injury is frequently induced by injuries, accidents or birth trauma. Upper limb function may be partially or totally lost after injury, or left permanently disabled. With the de-velopment of various medical technologies, different types of interventions are used, but their effectiveness is wide ranging. Many repair methods have phasic characteristics, i.e., repairs are done in different phases. This study explored research progress and hot topic methods for pro-tection after brachial plexus injury, by analyzing 1,797 articles concerning the repair of brachial plexus injuries, published between 2004 and 2013 and indexed by the Science Citation Index database. Results revealed that there are many methods used to repair brachial plexus injury, and their effects are varied. Intervention methods include nerve transfer surgery, electrical stimula-tion, cell transplantation, neurotrophic factor therapy and drug treatment. Therapeutic methods in this ifeld change according to the hot topic of research.

    In the San Antonio Uniformed Services Health Education Consortium Infectious Diseases Fellowship program, didactic lecture formats were previously used to present training in interdisciplinary topics, journal discussions, and core curriculum topics, but herein is described the recent modification of the fellowship's teaching techniques along with a satisfaction survey. The initial modification to the curriculum included the institution of debates covering controversial core curriculum topics in parliamentary fashion. The second change was the teaching of interdisciplinary topics utilizing a conference moderator. To evaluate the impact of the new teaching strategies, an anonymous Likert-based survey was distributed to the staff and fellows. The staff and fellows were uniformly satisfied with the changes in the curriculum and new strategies are preferred over the traditional teaching methods. Creating innovative forums to enhance the education of trainees has improved fellow and staff satisfaction with the teaching of these topics.

    Li, Long; Nagai, Kotobu; Yin, Fuxing

    2008-04-01

    Layered composite materials have become an increasingly interesting topic in industrial development. Cold roll bonding (CRB), as a solid phase method of bonding same or different metals by rolling at room temperature, has been widely used in manufacturing large layered composite sheets and foils. In this paper, we provide a brief overview of a technology using layered composite materials produced by CRB and discuss the suitability of this technology in the fabrication of layered composite materials. The effects of process parameters on bonding, mainly including process and surface preparation conditions, have been analyzed. Bonding between two sheets can be realized when deformation reduction reaches a threshold value. However, it is essential to remove surface contamination layers to produce a satisfactory bond in CRB. It has been suggested that the degreasing and then scratch brushing of surfaces create a strong bonding between the layers. Bonding mechanisms, in which the film theory is expressed as the major mechanism in CRB, as well as bonding theoretical models, have also been reviewed. It has also been showed that it is easy for fcc structure metals to bond compared with bcc and hcp structure metals. In addition, hardness on bonding same metals plays an important part in CRB. Applications of composites produced by CRB in industrial fields are briefly reviewed and possible developments of CRB in the future are also described. Corrections were made to the abstract and conclusion of this article on 18 June 2008. The corrected electronic version is identical to the print version.

    2007-07-01

    The first ever symposium dedicated solely to drug delivery to the nail following topical application was held on the 2nd April 2007, in London, UK, organised by Dr Clive Roper (Charles River Laboratories, Scotland) and Dr Sudaxshina Murdan (School of Pharmacy, University of London, UK), under the auspices of Skin Forum. The 1-day meeting was attended by approximately 35 delegates from industry, academia and hospitals, and provided a much-needed forum for the presentation and discussion of research and problems in this emerging field. Topical drug delivery is especially suitable for onychomycosis (fungal infections of the nail plate and/or nail bed) and nail psoriasis, which affect 2 - 13 and 1 - 3% of the general population, respectively, and make up the bulk of nail disorders. Topical therapy would avoid the adverse events and drug interactions of systemic antifungal agents and the pain of injection when antipsoriatic agents are injected into affected nail folds. However, successful topical therapy is extremely challenging due to the very low permeability of the nail plate. Five speakers spoke about various aspects of topical drug delivery to the nail, including review of the nail plate structure, function, diseases, their existing therapies (systemic and topical), limitations and global sales. The need for effective topical drug delivery to the nail to overcome the problems associated with present treatment, and the fact that there are few topical formulations available for the treatment of nail fungal infections and psoriasis, and the even fewer effective formulations, was highlighted.

    Wireless radio communications systems form the basis for mobile network connections in the digital society. A limited amount of radio spectrum and a spatially densified use of wireless communications systems require a resource-efficient use of the spectrum. Mechanisms of cognitive radio may hold the key to a more efficient use of the available spectrum under consideration of quality of service requirements. These mechanisms take advantage of location-specific knowledge of the wireless channel occupation in the dimensions of frequency, time, location and direction in space and therefore enable co-existent and reliable wireless communication. The authors give an introduction to the status of cognitive wireless communication technology, which represents the starting point of a series of research projects promoted by BMBF during 2012-2014.

    Do scientists follow hot topics in their scientific investigations? In this paper, by performing analysis to papers published in the American Physical Society (APS) Physical Review journals, it is found that papers are more likely to be attracted by hot fields, where the hotness of a field is measured by the number of papers belonging to the field. This indicates that scientists generally do follow hot topics. However, there are qualitative differences among scientists from various countries, among research works regarding different number of authors, different number of affiliations and different number of references. These observations could be valuable for policy makers when deciding research funding and also for individual researchers when searching for scientific projects.

    In ocular tissue, arachidonic acid is metabolized by cyclooxygenase to prostaglandins which are the most important lipid derived mediators of inflammation. Presently nonsteroidal anti-inflammatory drugs (NSAIDs) which are cyclooxygenase (COX) inhibitors are being used for the treatment of inflammatory disorders. NSAIDs used in ophthalmology, topically, are salicylic-, indole acetic-, aryl acetic-, aryl propionic- and enolic acid derivatives. NSAIDs are weak acids with pKa mostly between 3.5 a...

    Full Text Available How is the portrait of the Brazilian scientific production in Social Psychology of the past few years? This study aims to address especifically this question, by visiting the articles published by Brazilian scholars since 1980, all of whom have been recognized and sponsored by the Brazilian National Council on Scientific and Technological Development (CNPq. Production from 80 Brazilian researchers was analysed, based on phenomena traditionally studied by Social Psychologists (e.g., Social Influence, which served as a priori categories. Articles that reflect studies developed in 5 geopolitical regions of the country, but data showed regions South and Southeast with the highest concentration in terms of academic production. Such finding is discussed in terms of the influence of an individualist culture on Brazilian research. Observing the main Social Psychology topics studied by Brazilians, it was noticed a centrality of the "Psychological" approach to Social Psychology, mainly originated in English-speaking countries.

  12. How can we enhance girls' interest in scientific topics?

    Science.gov (United States)

    Kerger, Sylvie; Martin, Romain; Brunner, Martin

    2011-12-01

    Girls are considerably less interested in scientific subjects than boys. One reason may be that scientific subjects are considered to be genuinely masculine. Thus, being interested in science may threaten the self-perception of girls as well as the femininity of their self-image. If scientific topics that are considered to be stereotypically feminine were chosen, however, this potential threat might be overcome which, in turn, might lead to an increase in girls' interest in science. This hypothesis was empirically tested by means of two studies. Participants were 294 (Study 1) and 190 (Study 2) Grade 8 to Grade 9 students. Gender differences in students' interest in masculine and feminine topics were investigated for a range of scientific concepts (Study 1) as well as for a given scientific concept (Study 2) for four scientific subjects (i.e., biology, physics, information technology, and statistics), respectively. Both studies indicated that the mean level of girls' scientific interest was higher when scientific concepts were presented in the context of feminine topics and boys' level of scientific interests was higher when scientific concepts were presented in the context of masculine topics. Girls' interest in science could be substantially increased by presenting scientific concepts in the context of feminine topics. Gender differences as well as individual differences in the level of interest in scientific topics may be taken into account by creating learning environments in which students could select the context in which a certain scientific concept is embedded. ©2011 The British Psychological Society.

  16. Integrating ethical topics in a traditional computer science course

    1994-12-31

    It is never hard to find additional, often unconventional, topics which seem to beg inclusion in standard courses. A dynamic discipline like computer science usually provides a steady stream of new technical ideas to vie for time and attention with more traditional material. As difficult as it may be to keep standard CS courses up-to-date with technical innovations, it often seems even more difficult to include non-technical topics even when there is universal agreement on their importance, Inevitably the question of whether or not such inclusion will compromise the technical content of the course arises. This paper describes an attempt to include two such topics in a traditional course in data structures. The two topics are writing and ethics and, although the effort concentrates on the inclusion of ethical questions in a standard CS course, writing is the vehicle for accomplishing this goal. Furthermore, the inclusion writing in the CS curriculum is certainly recognized as a desirable outcome.

    Full Text Available Drug delivery across the skin is used for several millennia to ease gastrointestinal (GI ailments in Traditional Persian Medicine (TPM. TPM topical remedies are generally being applied on the stomach, lower abdomen, lower back and liver to alleviate GI illnesses such as dyspepsia, gastritis, GI ulcers, inflammatory bowel disease, intestinal worms and infections. The aim of the present study is to survey the topical GI remedies and plant species used as ingredients for these remedies in TPM. In addition, pharmacological activities of the mentioned plants have been discussed. For this, we searched major TPM textbooks to find plants used to cure GI problems in topical use. Additionally, scientific databases were searched to obtain pharmacological data supporting the use of TPM plants in GI diseases. Rosa × damascena, Pistacia lentiscus, Malus domestica, Olea europaea and Artemisia absinthium are among the most frequently mentioned ingredients of TPM remedies. β-asarone, amygdalin, boswellic acids, guggulsterone, crocin, crocetin, isomasticadienolic acid, and cyclotides are the most important phytochemicals present in TPM plants with GI-protective activities. Pharmacological studies demonstrated GI activities for TPM plants supporting their extensive traditional use. These plants play pivotal role in alleviating GI disorders through exhibiting numerous activities including antispasmodic, anti-ulcer, anti-secretory, anti-colitis, anti-diarrheal, antibacterial and anthelmintic properties. Several mechanisms underlie these activities including the alleviation of oxidative stress, exhibiting cytoprotective activity, down-regulation of the inflammatory cytokines, suppression of the cellular signaling pathways of inflammatory responses, improving re-epithelialization and angiogenesis, down-regulation of anti-angiogenic factors, blocking activity of acetylcholine, etc.

    Full Text Available This paper offers new data to support findings about Topic extraction from adverbial clauses. Since such clauses are strong islands, they should not allow extraction of any kind, but we show here that if the appropriate conditions are met, Topics of the CLLD kind in Romance can move out of them. We propose that two conditions must be met for such movement to be possible: the first is that the adverbial clause must have undergone topicalisation in the first place; the second is that the adverbial clause is inherently topical from a semantic viewpoint. Contrast with other language families (Germanic, Quechua and Japanese is provided and the semantic implications of the proposal are briefly discussed. Keywords: topicalisation; Clitic Left Dislocation; syntactic islands; adverbial clauses Este artículo ofrece nuevos datos sobre la extracción de Tópicos desde oraciones subordinadas adverbiales. Dado que dichas oraciones son islas fuertes, no deberían permitir extracción de ningún tipo, pero mostramos que si se dan las condiciones apropiadas, los Tópicos del tipo CLLD en lenguas románicas pueden desplazarse fuera de ellas. Proponemos que se deben cumplir dos condiciones para que ese movimiento sea posible: la primera es que la propia subordinada adverbial se haya topicalizado en primer lugar; la segunda es que la subordinada adverbial sea inherentemente un Tópico desde el punto de vista semántico.

    2016-02-01

    The tactile perception is essential for all types of topical formulations (cosmetic, pharmaceutical, medical device) and the possibility to predict the sensorial response by using instrumental methods instead of sensory testing would save time and cost at an early stage product development. Here, we report on an instrumental evaluation method using tactile friction measurements to estimate perceptual attributes of topical formulations. Friction was measured between an index finger and an artificial skin substrate after application of formulations using a force sensor. Both model formulations of liquid crystalline phase structures with significantly different tactile properties, as well as commercial pharmaceutical moisturizing creams being more tactile-similar, were investigated. Friction coefficients were calculated as the ratio of the friction force to the applied load. The structures of the model formulations and phase transitions as a result of water evaporation were identified using optical microscopy. The friction device could distinguish friction coefficients between the phase structures, as well as the commercial creams after spreading and absorption into the substrate. In addition, phase transitions resulting in alterations in the feel of the formulations could be detected. A correlation was established between skin hydration and friction coefficient, where hydrated skin gave rise to higher friction. Also a link between skin smoothening and finger friction was established for the commercial moisturizing creams, although further investigations are needed to analyse this and correlations with other sensorial attributes in more detail. The present investigation shows that tactile friction measurements have potential as an alternative or complement in the evaluation of perception of topical formulations. © 2015 John Wiley & Sons A/S.

    Full Text Available Priscilla Xinhui Wang, Victor Teck Chang Koh, Jin Fong ChengDepartment of Ophthalmology, National University Health System, SingaporeAbstract: Topical Bimatoprost is a common and popular prostaglandin analog used as an ocular hypotensive agent in the treatment of glaucoma. Side effects include ocular hyperaemia, ocular pruritus, and periocular and iris pigmentary changes. Perioribital lipodystrophy is another well-documented outcome associated with chronic use of topical bimatoprost, which results in periorbital hallowing, upper eyelid sulcus deepening, eyelid retraction and enophthalmos. We report an unusual case of periocular muscle atrophy and weakness from unilateral topical bimatoprost use. Our patient had primary angle closure and experienced a right upper eyelid ptosis 2 months after she started to use topical bimatoprost in that eye. Clinical measurements of her eyelids clearly showed reduction in the function of her right levator muscle, suggesting that effects of topical bimatoprost may not be limited to periorbital fat. She was advised to stop topical bimatoprost and right ptosis correction surgery with levator muscle advancement was performed successfully. Ophthalmologists and patients should be aware of this potential rare side effect of topical bimatoprost, as it may be potentially disfiguring, especially with monocular use. However, its exact mechanism of action needs to be clarified further.Keywords: prostaglandin analog, levator, muscle atrophy, muscle weakness, ptosis, side effects

    Recent years have brought dramatic advances in the scientific understanding of fusion plasmas and in the generation of fusion power in the laboratory. Today, there is little doubt that fusion energy production is feasible. The challenge is to make fusion energy practical. As a result of the advances of the last few years, there are now exciting opportunities to optimize fusion systems so that an attractive new energy source will be available when it may be needed in the middle of the next century. The risk of conflicts arising from energy shortages and supply cutoffs, as well as the risk of severe environmental impacts from existing methods of energy production, are among the reasons to pursue these opportunities.

    2014-01-01

    Plantar warts are a common reason for dermatological consultations and their treatment can occasionally be a challenge. Plantar warts are benign lesions produced by the human papillomavirus (HPV) that often fail to respond to habitual treatment. Cidofovir is a potent antiviral drug that acts competitively, inhibiting viral DNA polymerase. Our aim was to assess the efficacy and safety of cidofovir cream for the treatment of viral plantar warts. We undertook a retrospective observational study of patients with plantar warts who received treatment with topical cidofovir between July 2008 and July 2011 at the Dermatology Service of the Hospital Costa del Sol, Marbella, Spain. Data about the rate of treatment response, the adverse effects, and recurrences, as well as the characteristics of the patient cohort, were recorded. We identified 35 patients who had received some previous treatment. The usual concentration was 3% (in 33 of 35 cases), applied twice a day (in 31 of 35 cases). A greater or lesser response was noted in 28 cases. There were two recurrences. Topical cidofovir seems to be a useful alternative for the therapeutic management of recalcitrant plantar common warts that fail to respond to usual treatment.

    2009-01-01

    Topic indexing is the task of identifying the main topics covered by a document. These are useful for many purposes: as subject headings in libraries, as keywords in academic publications and as tags on the web. Knowing a document’s topics helps people judge its relevance quickly. However, assigning topics manually is labor intensive. This thesis shows how to generate them automatically in a way that competes with human performance. Three kinds of indexing are investigated: term assignment, a task commonly performed by librarians, who select topics from a controlled vocabulary; tagging, a popular activity of web users, who choose topics freely; and a new method of keyphrase extraction, where topics are equated to Wikipedia article names. A general two-stage algorithm is introduced that first selects candidate topics and then ranks them by significance based on their properties. These properties draw on statistical, semantic, domain-specific and encyclopedic knowledge. They are combined using a machine learn...

  1. Topic prominence in Chinese EFL learners’ interlanguage

    Directory of Open Access Journals (Sweden)

    Shaopeng Li

    2014-01-01

    Full Text Available The present study aims to investigate the general characteristics of topicprominent typological interlanguage development of Chinese learners of English in terms of acquiring subject-prominent English structures from a discourse perspective. Topic structures mainly appear in Chinese discourse in the form of topic chains (Wang, 2002; 2004. The research target are the topic chain, which is the main topic-prominent structure in Chinese discourse, and zero anaphora, which is the most common topic anaphora in the topic chain. Two important findings emerged from the present study. First, the characteristics of Chinese topic chains are transferrable to the interlanguage of Chinese EFL learners, thus resulting in overgeneralization of the zero anaphora. Second, the interlanguage discourse of Chinese EFL learners reflects a change of the second language acquisition process from topic-prominence to subject-prominence, thus lending support to the discourse transfer hypothesis.

    Full Text Available The objective of this study is to analyze the educational practices of using Blackboard in blended learning environments with students of higher education to understand the relationship between technological appropriation and standards of educational technology. To achieve that goal, the following research question was raised: ¿To what extent are the standards of education technology with the appropriation of technology in blended learning environments in higher educa­tion related? The contextual framework of this work includes the following topics: the institution, teaching, teachers and students. The design methodology that was used is of a correlation type. Correlations were carried out to determine the frequency and level in the technological standards as well as the appropriation of technology. In the comparison of the results obtained by the students, the teachers and the platform; we found that students in the school study showed a high degree of technology ownership and this was the same for the performance shown on the technological standards. It was established that teachers play a key role in developing the techno­logical appropriation of students and performance in technology standards.

  3. Topical Application of Fingolimod Perturbs Cutaneous Inflammation.

    The prevalence of allergies, including rhinitis, eczema, and anaphylaxis, is rising dramatically worldwide. This increase is especially problematic in children who bear the greatest burden of this rising trend. Increasing evidence identifies neutrophils as primary perpetrators of the more severe and difficult to manage forms of inflammation. A newly recognized mechanism by which neutrophils are recruited during the early phase of histamine-induced inflammation involves the sphingosine kinase (SK)/sphingosine-1-phosphate axis. This study examines whether topical application of fingolimod, an established SK/sphingosine-1-phosphate antagonist already in clinical use to treat multiple sclerosis, may be repurposed to treat cutaneous inflammation. Using two mouse models of ear skin inflammation (histamine- and IgE-mediated passive cutaneous anaphylaxis) we topically applied fingolimod prophylactically, as well as after establishment of the inflammatory response, and examined ear swelling, SK activity, vascular permeability, leukocyte recruitment, and production of proinflammatory mediators. The present study reveals that when applied topically, fingolimod attenuates both immediate and late-phase responses to histamine with reduced extravasation of fluid, SK-1 activity, proinflammatory cytokine and chemokine production, and neutrophil influx and prevents ear swelling. Intravital microscopy demonstrates that histamine-induced neutrophil rolling and adhesion to the postcapillary venules in the mouse ears is significantly attenuated even after 24 h. More importantly, these effects are achievable even once inflammation is established. Translation into humans was also accomplished with epicutaneous application of fingolimod resolving histamine-induced and allergen-induced inflammatory reactions in forearm skin. Overall, this study demonstrates, to our knowledge for the first time, that fingolimod may be repurposed to treat cutaneous inflammation.

    2013-07-01

    The emergence of quality by design as a relatively new systematic science and risk-based approach has added a new dimension to pharmaceutical development and manufacturing. This review attempts to discuss the quality by design elements and concepts applied for topical semisolid products. Quality by design begins with defining a quality target product profile as well as critical quality attributes. Subsequently, this is followed by risk identification/risk analysis/risk evaluation to recognize critical material attributes and critical process parameters, in conjunction with design of experiments or other appropriate methods to establish control strategies for the drug product. Several design-of-experiment examples are included as practical strategies for the development and optimization of formulation and process for topical drug products.

    Clinical practice guideline (CPG) development starts with selecting appropriate topics, as resources to develop a guideline are limited. However, a standardized method for topic selection is commonly missing and the way different criteria are used to prioritize is not clear. To select and prioritize dermatological topics for CPG development and elucidate criteria dermatologists find important in selecting guideline topics. All 410 dermatologists in the Netherlands were asked to create a top 20 of dermatological topics for which a guideline would be desirable, regardless of existing guidelines. They also rated, on a 5-point Likert scale, 10 determinative criteria derived from a combined search in literature and across (inter)national guideline developers. Top 20 topics received scores ranging from 0.01 to 0.2 and combined scores yielded a total score. The 118 surveys (response 29%) identified 157 different topics. Melanoma, squamous cell carcinoma, basal cell carcinoma, psoriasis and atopic dermatitis are top priority guideline topics. Venous leg ulcer, vasculitis, varicose veins, urticaria, acne, Lyme borreliosis, cutaneous lupus erythematosus, pruritus, syphilis, lymphoedema, decubitus ulcer, hidradenitis suppurativa, androgenic alopecia and bullous pemphigoïd complete the top 20. A further 15 topics have overlapping confidence intervals. Mortality and healthcare costs are regarded as less important criteria in topic selection (P topics. Respondents mostly agree with (inter)national guideline programmes and literature concerning the criteria important to selecting guideline topics. © 2014 European Academy of Dermatology and Venereology.

  9. Topics in Open Topological Strings

    CERN Document Server

    Prudenziati, Andrea

    2010-01-01

    This thesis is based on some selected topics in open topological string theory which I have worked on during my Ph.D. It comprises an introductory part where I have focused on the points most needed for the later chapters, trading completeness for conciseness and clarity. Then, following [12], we discuss tadpole cancellation for topological strings where we mainly show how its implementation is needed for ensuring the same "odd" moduli decoupling encountered in the closed theory. Next we move to analyse how the open and closed effective field theories for the B model interact writing the complete Lagrangian. We first check it deriving some already known tree level amplitudes in term of target space quantities, and then we extend the recipe to new results; later we implement open closed duality from a target field theory perspective. This last subject is also analysed from a worldsheet point of view extending the analysis of [13]. Some ideas for future research are briefly reported.

    Haken, Hermann

    2004-01-01

    This book is an often-requested reprint of two classic texts by H. Haken: "Synergetics. An Introduction" and "Advanced Synergetics". Synergetics, an interdisciplinary research program initiated by H. Haken in 1969, deals with the systematic and methodological approach to the rapidly growing field of complexity. Going well beyond qualitative analogies between complex systems in fields as diverse as physics, chemistry, biology, sociology and economics, Synergetics uses tools from theoretical physics and mathematics to construct an unifying framework within which quantitative descriptions of complex, self-organizing systems can be made. This may well explain the timelessness of H. Haken's original texts on this topic, which are now recognized as landmarks in the field of complex systems. They provide both the beginning graduate student and the seasoned researcher with solid knowledge of the basic concepts and mathematical tools. Moreover, they admirably convey the spirit of the pioneering work by the founder of ...

    2010-01-01

    Distal colitis(DC) can be effectively treated with topical 5ASA agents.Suppositories target the rectum while enemas can reliably reach the splenic flexure.Used in combination with oral 5ASAs,the control of the inflammation is even more effective.Unfortunately,resistant DC does occur and can be extremely challenging to manage.In these patients,the use of steroids,immunosuppressants and the anti-tumor necrosis factor α agents are often required.These,however,can be associated with systemic side effects and are not always effective.The investigation of new topical therapeutic agents is thus required as they are rarely associated with significant blood drug levels and side effects are infrequent.Some of the agents that have been proposed for use in resistant distal colitis include butyrate,cyclosporine and nicotine enemas as well as tacrolimus suppositories and tacrolimus,ecabet sodium,arsenic,lidocaine,rebamipide and Ridogrel enemas.Some of these agents have demonstrated impressive results but the majority of the agents have only been assessed in small open-labelled patient cohorts.Further work is thus required with the investigation of promising agents in the context of randomized double-blinded placebo controlled trials.This review aims to highlight those potentially effective therapies in the management of resistant distal colitis and to promote interest in furthering their investigation.

    2012-01-01

    We develop the multilingual topic model for unaligned text (MuTo), a probabilistic model of text that is designed to analyze corpora composed of documents in two languages. From these documents, MuTo uses stochastic EM to simultaneously discover both a matching between the languages and multilingual latent topics. We demonstrate that MuTo is able to find shared topics on real-world multilingual corpora, successfully pairing related documents across languages. MuTo provides a new framework for creating multilingual topic models without needing carefully curated parallel corpora and allows applications built using the topic model formalism to be applied to a much wider class of corpora.

    2017-06-22

    Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and promote healing, and there are many options to choose from including alginate, hydrocolloid and protease-modulating dressings. Topical agents have also been used as alternatives to dressings in order to promote healing.A clear and current overview of all the evidence is required to facilitate decision-making regarding the use of dressings or topical agents for the treatment of pressure ulcers. Such a review would ideally help people with pressure ulcers and health professionals assess the best treatment options. This review is a network meta-analysis (NMA) which assesses the probability of complete ulcer healing associated with alternative dressings and topical agents. To assess the effects of dressings and topical agents for healing pressure ulcers in any care setting. We aimed to examine this evidence base as a whole, determining probabilities that each treatment is the best, with full assessment of uncertainty and evidence quality. In July 2016 we searched the Cochrane Wounds Specialised Register; the Cochrane Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid MEDLINE (In-Process & Other Non-Indexed Citations); Ovid Embase and EBSCO CINAHL Plus. We also searched clinical trials registries for ongoing and unpublished studies, and scanned reference lists of relevant included studies as well as reviews, meta-analyses, guidelines and health technology reports to identify additional studies. There were no restrictions with respect to language, date of publication or study setting. Published or unpublished randomised controlled trials (RCTs) comparing the effects of at least one of the following interventions with any other intervention in the treatment of pressure ulcers (Stage 2 or above): any dressing, or any topical agent applied directly

    Full Text Available Bilingual topic detection is a vital application of natural language processing in the Internet plus Era and trend of economic globalization. At present, the method of bilingual topic detection can’t solve the problem of bilingual topic inconsistent distribution. Aiming at the shortcoming, this paper introduces a based on maximal clique method to find bilingual topic detection of Chinese and Thai feature words. First of all, extract the information of news with keywords of each Chinese and Thai documents through the TextRank algorithm. Next, disambiguate by means of the similarity combined with Chinese and Thai dictionary. Then, use credible association rules to cluster Chinese and Thai feature words, which generates maximal clique of bilingual topic. Finally, cluster similar maximal clique of topic to obtain the collection of final topic. According to the needs of users, the method can recommend a bilingual topic of different sizes. The test of Chinese and Thai news texts in January 2016 made good achievement. From the perspective of cross-language word clustering, the algorithm effectively solves the problem of inconsistency of bilingual topic distribution reasonably, and has the advantages of no need to estimate the number of topics and low time complexity, so it is suitable for the application of online discovery in ilingual topic.

    Knowledge of ENT is important for many doctors, but undergraduate time is limited. This study aimed to identify what is thought about ENT knowledge amongst non-ENT doctors, and the key topics that the curriculum should focus on. Doctors were interviewed about their views of ENT knowledge amongst non-ENT doctors, and asked to identify key topics. These topics were then used to devise a questionnaire, which was distributed to multiple stakeholders in order to identify the key topics. ENT knowledge was generally thought to be poor amongst doctors, and it was recommended that undergraduate ENT topics be kept simple. The highest rated topics were: clinical examination; when to refer; acute otitis media; common emergencies; tonsillitis and quinsy; management of ENT problems by non-ENT doctors; stridor and stertor; otitis externa; and otitis media with effusion. This study identified a number of key ENT topics, and will help to inform future development of ENT curricula.

    Yıldırım, Ahmet; Üsküdarlı, Suzan; Özgür, Arzucan

    2016-01-01

    Twitter is an extremely high volume platform for user generated contributions regarding any topic. The wealth of content created at real-time in massive quantities calls for automated approaches to identify the topics of the contributions. Such topics can be utilized in numerous ways, such as public opinion mining, marketing, entertainment, and disaster management. Towards this end, approaches to relate single or partial posts to knowledge base items have been proposed. However, in microblogging systems like Twitter, topics emerge from the culmination of a large number of contributions. Therefore, identifying topics based on collections of posts, where individual posts contribute to some aspect of the greater topic is necessary. Models, such as Latent Dirichlet Allocation (LDA), propose algorithms for relating collections of posts to sets of keywords that represent underlying topics. In these approaches, figuring out what the specific topic(s) the keyword sets represent remains as a separate task. Another issue in topic detection is the scope, which is often limited to specific domain, such as health. This work proposes an approach for identifying domain-independent specific topics related to sets of posts. In this approach, individual posts are processed and then aggregated to identify key tokens, which are then mapped to specific topics. Wikipedia article titles are selected to represent topics, since they are up to date, user-generated, sophisticated articles that span topics of human interest. This paper describes the proposed approach, a prototype implementation, and a case study based on data gathered during the heavily contributed periods corresponding to the four US election debates in 2012. The manually evaluated results (0.96 precision) and other observations from the study are discussed in detail.

    To compare the pain rates, comfort levels and safety between conventional topical anaesthesia and the application of a long lasting lidocaine soaked film or contact anaesthesia. Fifty patients undergoing conventional trabeculectomy with or without Mitomycin-C were included. One half received topical anaesthesia and the other half contact anaesthesia in a random fashion. Pain and discomfort rates before, during and after surgery were evaluated on a scale from 0 to 5, also, surgeon subjective stress and complications observed were included in the clinical protocol. Significant differences were found between both groups regarding pain rates, during and after surgery, and surgeon stress level. Sedation and change of anesthesic method were required more frequently by the patients included in the topical anaesthesia group. Topical anaesthesia provides sufficient level of anaesthesia for performing a trabeculectomy. Nevertheless pain rate differences between contact and conventional topical anaesthesia were patent during and after surgery. Contact anaesthesia appears to be a valid and practical alternative in a wide range of patients undergoing glaucoma surgery.

    Fungal infections are amongst the most commonly encountered diseases affecting the skin. Treatment approaches include both topical and oral antifungal agents. The topical route is generally preferred due to the possible side effects of oral medication. Advances in the field of formulation may soon render outdated conventional products such as creams, ointments and gels. Several carrier systems loaded with antifungal drugs have demonstrated promising results in the treatment of skin fungal infections. Examples of these newer carriers include micelles, lipidic systems such as solid lipid nanoparticles and nanostructured lipid carriers, microemulsions and vesicular systems such as liposomes, niosomes, transfersomes, ethosomes, and penetration enhancer vesicles.

    This paper reviews recent topics of clinical application of functional electrical stimulation (FES) for the paralyzed extremities in Japan. Transcutaneous and percutaneous FES systems have been clinically used in Japan. Candidates of extremity FES arer mostly stroke and spinal cord injury patients. By using percutaneous FES system, all of the joints of the upper extremity including the shoulder have been controlled for activities of daily living in the hemiplegic patient. Simultaneous FES control of the hand and wrist and the bilateral hands have also been achieved in C5 and C6 quadriplegics, respectively. Hybrid FES systems using percutaneous and surface electrodes, where FES is used in combination with orthoses, have been applied to the paraplegics because they are highly practical for assisting their locomotive activities. Percutaneous FES have been also provided the amyotropic lateral sclerosis patients with standing up motion. A total implant FES system with 16 output channels is currently developing as a next generation FES system.

    2014-06-01

    High precision experiments at low energies on discrete and continuous symmetries offer the possibility to search for New Physics beyond the Standard Model. Examples are dedicated searches for violations of the C, P, CP and CPT as well as of Lorentz Invariance using matter and anti-matter. Atomic parity violation was not only essential in the past to verify the Standard Model, still today it has a potential to find Z' bosons, leptoquarks or dark matter. Electric Dipole Moments (EDMs) may provide clues to explain the matter-antimatter asymmetry in the universe. There is at present a some 4 standard deviations discrepancy between theory and experiment for the muon magnetic anomaly. At the same time while providing important information on physics beyond the Standard Model, new technology such as precise clocks is developed along with the experiments motivated by fundamental physics questions. This article summarizes an overview talk that was concerned primarily with a selection of topics from a very rich field, in particular such that were not covered otherwise at this conference.

  7. Topical therapies in the management of chronic pain.

    Stanos, Steven P; Galluzzi, Katherine E

    2013-07-01

    Chronic pain, whether localized or generalized, is a widespread, often debilitating condition affecting > 25% of adults in the United States. Oral agents are the cornerstone of chronic pain treatment, but their use may be limited in certain patients, particularly the elderly. Topical therapies offer advantages over systemically administered medications, including the requirement of a lower total systemic daily dose for patients to achieve pain relief, site-specific drug delivery, and avoidance of first-pass metabolism, major drug interactions, infections, and systemic side effects. Several types of topical agents have been shown to be useful in the treatment of patients with chronic pain. Both capsaicin and topical diclofenac have been shown to be effective in the treatment of patients with chronic soft-tissue pain. In patients with hand and knee osteoarthritis (OA), the American College of Rheumatology generally recommends oral treatments (acetaminophen, oral nonsteroidal anti-inflammatory drugs [NSAIDs], tramadol, and intra-articular corticosteroids) and topical NSAIDs equally, favoring topical agents only for patients who have pre-existing gastrointestinal risk or are aged ≥ 75 years. Topical NSAIDs have been shown to provide relief superior to that of placebo and comparable to that of oral ibuprofen. Similarly, ketoprofen gel has been shown to be superior to placebo and similar to oral celecoxib in reducing pain in patients with knee OA. Different formulations of topical diclofenac (including the diclofenac hydroxyethyl pyrrolidine patch, diclofenac sodium gel, and diclofenac sodium topical solution 1.5% w/w with dimethyl sulfoxide USP) have been shown to be superior to placebo and comparable to oral diclofenac in the treatment of patients with pain due to knee OA, with a lower incidence of gastrointestinal complaints than with the oral formulation. In patients with neuropathic pain, topical forms of both capsaicin and lidocaine have been shown to be useful

  8. Newer approaches in topical combination therapy for acne.

    Fu, Lisa W; Vender, Ronald B

    2011-10-01

    Acne vulgaris is a common chronic inflammatory cutaneous disease involving the pilosebaceous unit. Its pathophysiology is multifactorial and complex, including obstruction of the pilosebaceous unit due to increased sebum production, abnormal keratinization, proliferation of Propionibacterium acnes (P. acnes), and inflammation. Topical agents are the most commonly used therapy for acne. First generation topicals mainly consist of single agent retinoids, benzoyl peroxide (BPO) and antibacterials that target comedones, P. acnes, and inflammation. Novel topical therapies include combination products with advanced vehicle formulations that target multiple acne pathophysiologies and offer simplified treatment regimes. For example, the combination of clindamycin and tretinoin in a unique vehicle formulation allows for progressive follicle penetration and decreased irritation, resulting in increased efficacy. Furthermore, adapalene or clindamycin with BPO combinations target comedones, inflammation, and P. acnes synergistically. These newer combination products have the potential to increase both efficacy and patient adherence when compared with single agent treatment.

    Kindsvater, Carl E.

    1958-01-01

    the Euler, Froude, Reynolds, Weber, and Cauchy numbers are defined as essential tools for interpreting and using experimental data. The derivations of the energy and momentum equations are treated in detail. One-dimensional equations for steady nonuniform flow are developed, and the restrictions applicable to the equations are emphasized. Conditions of uniform and gradually varied flow are discussed, and the origin of the Chezy equation is examined in relation to both the energy and the momentum equations. The inadequacy of all uniform-flow equations as a means of describing gradually varied flow is explained. Thus, one of the definitive problems of river hydraulics is analyzed in the light of present knowledge. This report is the outgrowth of a series of short schools conducted during the spring and summer of 1953 for engineers of the Surface Water Branch, Water Resources Division, U. S. Geological Survey. The topics considered are essentially the same as the topics selected for inclusion in the schools. However, in order that they might serve better as a guide and outline for informal study, the arrangement of the writer's original lecture notes has been considerably altered. The purpose of the report, like the purpose of the schools which inspired it, is to build a simple but strong framework of the fundamentals of fluid mechanics. It is believed that this framework is capable of supporting a detailed analysis of most of the practical problems met by the engineers of the Geological Survey. It is hoped that the least accomplishment of this work will be to inspire the reader with the confidence and desire to read more of the recent and current technical literature of modern fluid mechanics.

  16. Topical ocular delivery of fluoroquinolones.

    Science.gov (United States)

    Pawar, Pravin; Katara, Rajesh; Mishra, Sushil; Majumdar, Dipak K

    2013-05-01

    Topical fluoroquinolones are used in ophthalmology to treat ocular infections. They are bactericidal and inhibit bacterial DNA replication by inhibiting DNA gyrase and topoisomerase. Fluoroquinolones possess two ionizable groups: a carboxylic group (pKa1 = 5.5 - 6.34) and a heterocyclic group (pKa2 = 7.6 - 9.3), in the nucleus, which acquire charge at pH above and below the isoelectric point (pI = 6.75 - 7.78). At isoelectric point, fluoroquinolones remain unionized and show enhanced corneal penetration but exhibit reduced aqueous solubility and the drug may precipitate from aqueous solution. Aqueous ophthalmic solutions of fluoroquinolones are obtained by using hydrochloride or mesylate salt which is acidic and irritating to the eyes. Hence, pH of the solution is kept between 5 and 7 to ensure aqueous solubility and minimum ocular irritation. This review gives an overview of various physicochemical and formulation factors affecting the ocular delivery of fluoroquinolones and strategies for getting higher ocular bioavailability for ocular delivery of fluoroquinolones. These strategies could be employed to improve efficacy of fluoroquinolones in eye preparation. Broad-spectrum antibacterials, such as the ophthalmic fluoroquinolones, are powerful weapons for treating and preventing potentially sight-threatening infections. The fourth-generation fluoroquinolones have quickly assumed an outstanding place in the ophthalmic applications. Especially valuable for their broad-spectrum coverage against Gram-positive and Gram-negative organisms, these agents have become the anti-infective of preference for many ophthalmologists. Moxifloxacin seems to be a promising powerful molecule among all fluoroquinolones for treatment of bacterial infections.

  17. Topical ocular delivery of NSAIDs.

    Ahuja, Munish; Dhake, Avinash S; Sharma, Surendra K; Majumdar, Dipak K

    2008-06-01

    In ocular tissue, arachidonic acid is metabolized by cyclooxygenase to prostaglandins which are the most important lipid derived mediators of inflammation. Presently nonsteroidal anti-inflammatory drugs (NSAIDs) which are cyclooxygenase (COX) inhibitors are being used for the treatment of inflammatory disorders. NSAIDs used in ophthalmology, topically, are salicylic-, indole acetic-, aryl acetic-, aryl propionic- and enolic acid derivatives. NSAIDs are weak acids with pKa mostly between 3.5 and 4.5, and are poorly soluble in water. Aqueous ophthalmic solutions of NSAIDs have been made using sodium, potassium, tromethamine and lysine salts or complexing with cyclodextrins/solubilizer. Ocular penetration of NSAID demands an acidic ophthalmic solution where cyclodextrin could prevent precipitation of drug and minimize its ocular irritation potential. The incompatibility of NSAID with benzalkonium chloride is avoided by using polysorbate 80, cyclodextrins or tromethamine. Lysine salts and alpha-tocopheryl polyethylene glycol succinate disrupt corneal integrity, and their use requires caution. Thus a nonirritating ophthalmic solution of NSAID could be formulated by dissolving an appropriate water-soluble salt, in the presence of cyclodextrin or tromethamine (if needed) in mildly acidified purified water (if stability permits) with or without benzalkonium chloride and polyvinyl alcohol. Amide prodrugs met with mixed success due to incomplete intraocular hydrolysis. Suspension and ocular inserts appear irritating to the inflamed eye. Oil drop may be a suitable option for insoluble drugs and ointment may be used for sustained effect. Recent studies showed that the use of colloidal nanoparticle formulations and the potent COX 2 inhibitor bromfenac may enhance NSAID efficacy in eye preparations.

  18. Usage-Oriented Topic Maps Building Approach

    Science.gov (United States)

    Ellouze, Nebrasse; Lammari, Nadira; Métais, Elisabeth; Ben Ahmed, Mohamed

    In this paper, we present a collaborative and incremental construction approach of multilingual Topic Maps based on enrichment and merging techniques. In recent years, several Topic Map building approaches have been proposed endowed with different characteristics. Generally, they are dedicated to particular data types like text, semi-structured data, relational data, etc. We note also that most of these approaches take as input monolingual documents to build the Topic Map. The problem is that the large majority of resources available today are written in various languages, and these resources could be relevant even to non-native speakers. Thus, our work is driven towards a collaborative and incremental method for Topic Map construction from textual documents available in different languages. To enrich the Topic Map, we take as input a domain thesaurus and we propose also to explore the Topic Map usage which means available potential questions related to the source documents.

  19. Tracking topic birth and death in LDA.

    Energy Technology Data Exchange (ETDEWEB)

    Wilson, Andrew T.; Robinson, David Gerald

    2011-09-01

    Most topic modeling algorithms that address the evolution of documents over time use the same number of topics at all times. This obscures the common occurrence in the data where new subjects arise and old ones diminish or disappear entirely. We propose an algorithm to model the birth and death of topics within an LDA-like framework. The user selects an initial number of topics, after which new topics are created and retired without further supervision. Our approach also accommodates many of the acceleration and parallelization schemes developed in recent years for standard LDA. In recent years, topic modeling algorithms such as latent semantic analysis (LSA)[17], latent Dirichlet allocation (LDA)[10] and their descendants have offered a powerful way to explore and interrogate corpora far too large for any human to grasp without assistance. Using such algorithms we are able to search for similar documents, model and track the volume of topics over time, search for correlated topics or model them with a hierarchy. Most of these algorithms are intended for use with static corpora where the number of documents and the size of the vocabulary are known in advance. Moreover, almost all current topic modeling algorithms fix the number of topics as one of the input parameters and keep it fixed across the entire corpus. While this is appropriate for static corpora, it becomes a serious handicap when analyzing time-varying data sets where topics come and go as a matter of course. This is doubly true for online algorithms that may not have the option of revising earlier results in light of new data. To be sure, these algorithms will account for changing data one way or another, but without the ability to adapt to structural changes such as entirely new topics they may do so in counterintuitive ways.

    Topic models can be seen as a generalization of the clustering problem, in that they posit that observations are generated due to multiple latent factors (e.g. the words in each document are generated as a mixture of several active topics, as opposed to just one). This increased representational power comes at the cost of a more challenging unsupervised learning problem of estimating the topic probability vectors (the distributions over words for each topic), when only the words are observed and the corresponding topics are hidden. We provide a simple and efficient learning procedure that is guaranteed to recover the parameters for a wide class of mixture models, including the popular latent Dirichlet allocation (LDA) model. For LDA, the procedure correctly recovers both the topic probability vectors and the prior over the topics, using only trigram statistics (i.e. third order moments, which may be estimated with documents containing just three words). The method, termed Excess Correlation Analysis (ECA), is...

    The purpose of the Colliding Beams Experiment Department at Fermilab was to bring about collisions of the stored beams in the energy Doubler/Saver and Main Ring, and construct experimental areas with appropriate detectors. To explore the feasibility of using the Main Ring as a storage device, several studies were carried out to investigate beam growth, loss, and the backgrounds in detectors at possible intersection regions. This range of developments constituted the major topics at the 1977 Summer Study reported here. Emphasis in part two is on detector considerations and general topics. 22 papers from this part are included in the data base. (GHT)

    The Allison Gas Turbine Division (Allison) of General Motors Corporation conducted the Advanced Turbine Systems (ATS) program feasibility study (Phase I) in accordance with the Morgantown Energy Technology Center`s (METC`s) contract DE-AC21-86MC23165 A028. This feasibility study was to define and describe a natural gas-fired reference system which would meet the objective of {ge}60% overall efficiency, produce nitrogen oxides (NO{sub x}) emissions 10% less than the state-of-the-art without post combustion controls, and cost of electricity of the N{sup th} system to be approximately 10% below that of the current systems. In addition, the selected natural gas-fired reference system was expected to be adaptable to coal. The Allison proposed reference system feasibility study incorporated Allison`s long-term experience from advanced aerospace and military technology programs. This experience base is pertinent and crucial to the success of the ATS program. The existing aeroderivative technology base includes high temperature hot section design capability, single crystal technology, advanced cooling techniques, high temperature ceramics, ultrahigh turbomachinery components design, advanced cycles, and sophisticated computer codes.

  19. Spoken Document Retrieval Leveraging Unsupervised and Supervised Topic Modeling Techniques

    Chen, Kuan-Yu; Wang, Hsin-Min; Chen, Berlin

    This paper describes the application of two attractive categories of topic modeling techniques to the problem of spoken document retrieval (SDR), viz. document topic model (DTM) and word topic model (WTM). Apart from using the conventional unsupervised training strategy, we explore a supervised training strategy for estimating these topic models, imagining a scenario that user query logs along with click-through information of relevant documents can be utilized to build an SDR system. This attempt has the potential to associate relevant documents with queries even if they do not share any of the query words, thereby improving on retrieval quality over the baseline system. Likewise, we also study a novel use of pseudo-supervised training to associate relevant documents with queries through a pseudo-feedback procedure. Moreover, in order to lessen SDR performance degradation caused by imperfect speech recognition, we investigate leveraging different levels of index features for topic modeling, including words, syllable-level units, and their combination. We provide a series of experiments conducted on the TDT (TDT-2 and TDT-3) Chinese SDR collections. The empirical results show that the methods deduced from our proposed modeling framework are very effective when compared with a few existing retrieval approaches.

  20. The Power of Combination Topical Therapy for Psoriasis.

    Science.gov (United States)

    Kircik, Leon H; Zografos, Panagiotis

    2015-10-01

    Psoriasis is a chronic inflammatory skin disease where the use of topical corticosteroids is a mainstream treatment. However, the continuous use of high potency topical corticosteroids is limited by a variety of well known adverse events which include, atrophy, and telangiectasia. Also, inhibition of lipid synthesis by steroids can cause impairment of the epidermal barrier, which is already disrupted in most of the inflammatory cutaneous disorders such as psoriasis. This will further lead to increase transepidermal water loss (TEWL), decreased hydration, dry skin, and irritation. On the other hand, topical vitamin D analogs directly affect keratinocyte proliferation and differentiation as well as modulation of epidermal lipids and antimicrobial peptides. Although the exact mechanism of action of topical vitamin D analogs is not well understood in the treatment of psoriasis, their efficacy and safety has been shown in several clinical trials over the years and they are widely used for psoriasis. Therefore, combination of topical steroids and vitamin D analogs may be a logical option for the treatment of psoriasis.

  1. Advances in the topical treatment of acne and rosacea.

    Acne and rosacea are common skin diseases which may present similarly and both involve inflammation. Both can result in significant cosmetic impairment and lead to quality of life decrements if not optimally treated. The conventional approach for both diseases involves the use of topical therapy to treat inflammatory lesions in combination, when needed, with a systemic or topical antibiotic. An important issue in the management of both diseases at present is the need to reduce antibiotic usage due to the increasing problem of bacterial resistance. One of the emerging treatment paradigms that is becoming increasingly useful as an antibiotic-sparing strategy is the use of procedural therapies in combination with medical management. Such procedural modalities include lasers, intense pulsed light (IPL), and photodynamic therapies (PDT). Topical regimens are used pre-treatment and following physical modalities for maintenance of remission.

    Morbus Ledderhose is a rare hyperproliferative disease of the plantar fascia, leading to the formation of nodules. Its origin is unknown. No causal therapy is available, and treatment remains symptomatic. Various therapeutic strategies to alleviate symptoms are available and are adapted to the severity of the disease. In early stages, conservative therapy including nonpharmacological, physical, and pharmacological treatments is applied. If the disease progresses, irradiation of the plantar surface, injections of steroids, shock wave therapy, and partial or complete fasciectomy as an ultimate therapy may be indicated. Novel experimental treatment options including application of fibrinolytic agents are currently being tested, but no controlled, randomized long-term studies are available. This review aims to provide a systematic overview of current established procedures and outlines novel experimental strategies for the treatment of morbus Ledderhose, including future avenues to treat this rare disease.

    Full Text Available Introduction: Topical antibiotics are the main step in the treatment of mild to moderate acne vulgaris. Erythromycin is one of the effective topical therapies for this disease. Zinc sulfate 5% solution was reported to be effective in treatment of acne vulgaris and rosacea. Aim: To compare the effectiveness and side effects of topical erythromycin in combination with zinc and erythromycin alone in treatment of mild to moderate acne vulgaris. Material and Methods: This single, blind, therapeutic, comparative study was done in the Department of Dermatology – Baghdad Teaching Hospital, Baghdad, Iraq; from May 2012 – August 2013.Scoring of acne was carried out and the patients were examined every two weeks for 10 weeks of treatment. One month after stopping drugs, patients were evaluated for drug complications and disease recurrence. Eighty patients fulfilling enrollment criteria were included in this study. Patients were divided into two groups: Group A (40 patients treated twice daily with topical erythromycin-zinc complex lotion and Group B (40 patients treated twice daily with topical 2% erythromycin gel. Results: Both topical erythromycin-zinc lotion and erythromycin gel were statistically an effective therapy starting after 6 weeks treatment and up to 4 weeks after stopping treatment. Erythromycin-zinc lotion was more effective and act earlier than erythromycin gel starting from 4 weeks of therapy till the end of treatment (after 10 week and even after 4 weeks after stopping the treatment (p value <0.0001. Conclusions: Erythromycin-zinc complex lotion was an effective and well tolerated topical therapy for mild to moderate inflammatory acne vulgaris and was more effective than erythromycin gel alone.
