    Full Text Available El éxito de la casa Wiley consiste, principalmente, en el fruto conseguido por el esfuerzo de sus proyectistas en lograr la diferenciación de funciones que se realizan en toda vida familiar. Con ello, se ha logrado armonizar dos elementos tal vez incompatibles: la pureza de la arquitectura moderna y las necesidades de toda vida en familia. ¿Por qué la gente no puede aprender a vivir en los espacios sin ventanas de Ledoux, ni en los prismas de cristal de Mies van der Rohe? Sencillamente, porque la gente necesita una zona para que la niña de la casa toque el piano mientras su mamá juega al bridge con sus amigas; necesita una casa, en la que se puedan desarrollar simultáneamente las actividades más diversas y en la que cada individuo de la familia tenga su lugar íntimo de recogimiento para el descanso o trabajo.

  7. SENSITIVE PERIODS RESEARCH IN THE PRECISION WITH THE ELEMENTARY SCHOOLBOYS

    Full Text Available The intervals of more or less intensive corporal, functional, motoric, intellectual, physical and social development appear in the ontogenetic development of each individual. The phenomenon of an unequal or, more exactly, skipping development of any of the given segments of the bio-psycho-social status, we often call sensibility periods or, more exactly, sensitive or critical periods. The research subject is the precision as a basic motoric ability from the aspect of its sensitive phases of the schoolboys aging from 7 to 15. All in total 373 schoolboys were included, that is, 18 schoolboys 7 years old, 36 of 8, 52 of 9, 47 of 10, 41 of 11, 37 of 12, 31 of 13, 46 of 14, and 64 of 15 years old.The research goal is the establishment of the sensitive phases of the precision development in the different schoolboys ages. The test sample was composed of the precision by hand and by foot in standing position and in movement. The acquired results and fi ndings of the research point out the existence of more or less expressed sensitive phases in the precision development in some ages, which brings to a conclusion that those sensitive phases should be respected, especially in the training process of those sports where the precision is one of the predominant motoric abilities, on which the sport results depend to a great extent. Practical reference of this research is that in the training process it is necesary to work on the precision improvement in those ages, in which the precision in the ontogenesy develops through a sensitive phase, that is, during its natural more intensive development.

    This study aimed to investigate the degree of research outcome in medical science subjects in Pakistan during the period 1996-2012. In this study, the research papers published in various global science journals during the period 1996-2012 were accessed. We recorded the total number of research documents having an affiliation with a Pakistan. The main source for information was Institute of Scientific Information (ISI) Web of Science, Thomson Reuters and SCI-mago/Scopus. In global science, Pakistan contributed 58133 research papers in all science and social sciences both in ISI and non ISI indexed journals. However, in medical sciences the total number of research papers from Pakistan are 25604, citable documents 23874, citations 128061, mean citations per documents 6.45 and mean Hirsch index is 35.33. In Pakistan, the upward trend of articles published in global medical science was from the period 1996-2008. However, from 2008 the trend is markedly declined. Pakistan significantly improved its international ranking positions in research during the period 2000-2008. However, the upward trend of research papers published in global medical science could not be retained and from the year 2008 the trend started declining. This trend of research papers further declined in year 2012 compared to year 2011. It is suggested that, Pakistan must take strategic steps to enhance the research culture and increase the research and development expenditure in the country.

    The research and development activities of the Seismology Section of the Bhabha Atomic Research Centre (BARC) at Bombay are reported for the period January 1982-December 1983 in the form of summaries. The Section's activities are mainly directed towards detection of underground nuclear explosions. During the report period 64 signals out of about 12000 seismograms which were examined were identified as the signals due to underground nuclear explosions. The instrumentation work for Kolar rockburst research was almost completed under the collaboration programme of BARC with Bharat Gold Mines Ltd. Analytical methods have been developed for interpreting the frequency-magnitude relation of earthquake. These methods will be useful in the seismic estimation of risk in case only restricted data involving events of low magnitude are available. A list of publications of the staff-members of the Section during the report period is given. (M.G.B.)

  10. Redirecting reproductive immunology research toward pregnancy as a period of temporary immune tolerance.

    Science.gov (United States)

    Gleicher, Norbert; Kushnir, Vitaly A; Barad, David H

    2017-04-01

    Referring to two recent publications, we here propose that clinical reproductive immunology has for decades stagnated because reproductive medicine, including assisted reproduction (AR), has failed to accept embryo implantation as an immune system-driven process, dependent on establishment of maternal tolerance toward the implanting fetal semi-allograft (and complete allograft in cases of oocyte donation). Pregnancy represents a biologically unique period of temporary (to the period of gestation restricted) tolerance, otherwise only known in association with parasitic infections. Rather than investigating the immune pathways necessary to induce this rather unique state of tolerance toward the rapidly growing parasitic antigen load of the fetus, the field, instead, concentrated on irrelevant secondary immune phenomena (i.e., "immunological noise"). It, therefore, does not surprise that interesting recent research, offering new potential insights into maternal tolerance during pregnancy, was mostly published outside of the field of reproductive medicine. This research offers evidence for existence of inducible maternal tolerance pathways with the ability of improving maternal fecundity and, potentially, reducing such late pregnancy complications as premature labor and preeclampsia/eclampsia due to premature abatement of maternal tolerance. Increasing evidence also suggests that tolerance-inducing immune pathways are similar in successful pregnancy, successful organ transplantation and, likely also in the tolerance of "self" (i.e., prevention of autoimmunity). Identifying and isolating these pathways, therefore, may greatly benefit all three of these clinical areas, and research in reproductive immunology should be accordingly redirected.

  11. Research of short-period variations of virtual height of ionosphere layers

    Akchurin, Adel; Bochkarev, Vladimir

    Some results of research of non-uniform structure of an ionosphere (generally for day time conditions) by digital ionosonde "Cyclon" are presented. The virtual height measurements were made by method with the increased accuracy. The technique of multipulse sounding realized on ionosonde "Cyclon" allows getting of the altitude accuracy up to 300 m. Such accuracy, in turn, enables to investigate more thin elements of non-uniform structure of the ionosphere. All measurements of reflection heights (generally from F layer) were made at fixed frequencies concern to quiet day time conditions for several day in August 2008 and February 2010. Measurements were carried out with a one-minute periodicity at ten frequencies in range of 3-3.45 MHz in August and 2.5-4.2 MHz in February. The analysis of time series of virtual heights (on the fixed working frequencies) was performed by an estimation of power spectral density on the basis of algorithm of multiple signal classification (MUSIC). The given method spectral estimation concerns to a class of the spectral methods based on the analysis of own values of an autocorrelation matrix. It provides the best characteristics of the resolution and estimation of frequencies in comparison with autoregressive method and Prony's method, is especial at low signal to noise ratio when these methods are not capable to resolve relatives on frequency of a sinusoid or other narrow-band spectral components. For series of measurements in August with one-minute periodicity the spectral analysis has revealed the basic the period of 15-20 minutes (both for F layer and for Es layer). Except for the basic period in spectra there are peaks at T 10, 35, 180 minutes (for F layer) and T 6 minutes (for Es layer). There are no predominant variations among the more short-period fluctuations.

    Jenkins, Dennis R.

    2012-01-01

    Since its earliest days, flight has been about pushing the limits of technology and, in many cases, pushing the limits of human endurance. The human body can be the limiting factor in the design of aircraft and spacecraft. Humans cannot survive unaided at high altitudes. There have been a number of books written on the subject of spacesuits, but the literature on the high-altitude pressure suits is lacking. This volume provides a high-level summary of the technological development and operational use of partial- and full-pressure suits, from the earliest models to the current high altitude, full-pressure suits used for modern aviation, as well as those that were used for launch and entry on the Space Shuttle. The goal of this work is to provide a resource on the technology for suits designed to keep humans alive at the edge of space. Hopefully, future generations will learn from the hard-fought lessons of the past. NASA is committed to the future of aerospace, and a key component of that future is the workforce. Without these men and women, technological advancements would not be possible.

    Schizophrenia is a severe behavioral syndrome of neurodevelopmental nature marked by primary or genuine motor abnormalities (GMA), which refer to spontaneous and medication-independent motor phenomena. Since motor dysfunction thus might be a consequence of events occurring during early childhood and adolescence, GMA can be detected in the period preceding manifest schizophrenia. However, the question whether motor system dysfunction might be a promising motor intermediate phenotype for schizophrenia remains unanswered. In this review, we systematically evaluate the evidence on GMA in healthy persons, individuals with schizotypal personality traits, persons at ultra-high risk for psychosis, and unaffected first-degree relatives of schizophrenia patients. What becomes evident is a continuum of GMA expression, which appears to be linked to abnormalities of cerebello-thalamo-cortical, fronto-parietal, and cortico-subcortical motor circuits. According to current evidence, motor dysfunction is a key aspect of the neurodevelopmental risk factor model of schizophrenia. Insights provided by this research will help promoting the RDoC Motor System construct and expand the clinical relevance of the motor domain in the period preceding manifest schizophrenia.

    Full Text Available The investigation device – small size periodic operation bioreactors, which are developed for the production of biogas from different organic, vegetable waste. The device operates by maintaining optimum operating temperature and oxygen concentration required for anaerobic treatment process inside the bioreactor. Under favorable conditions, organic substance is being degradated because of anaerobic processess, colonies of microorganisms grow, and methane bacteria produce CH4 – useful flammable gases, which can be used as natural gas analogue. The gas is stored in special tanks of gas – gas holders. A study was implemented by analizing five different loads, according to the mixing ratio of vegetables (potatoes and chicken manure waste. The quality and quantity of biogas was analized as well. It was found that the highest concentration of methane (67.8% was achieved by using a load consisting only of chicken manure, but after evaluation of biogas yield, it was found that the best result (according to the quantity of biogas, a high concentration of CH4 and time of load degradation is achieved using chicken manure and potato waste mix (relatively 70 and 30%. Mesophilic process temperature during the experiment was 33–35 °C, and oxygen concentration – 0.0–0.1%. After research implementation there will be an opportunity to create small size periodic operation bioreactors, which can be used in small farms or private houses, where the small amount of organic waste and manure are formed.

    The Watershed Allied Telemetry Experimental Research (WATER) is an intensively simultaneous airborne, satellite-borne and ground based remote sensing experiment aiming to improve the observability, understanding, and predictability of hydrological and related ecological processes at catchment scale. It was taken place in the Heihe River Basin, the second largest inland river basin in the arid regions of northwest China. WATER consists of the cold region, forest, and arid region hydrological experiments as well as a hydrometeorology experiment. It was divided into 4 phases, namely, the experiment planning period, pre-observation period, intensive observation period (IOP) and persistent observation period. The field campaigns have been completed, with the IOP lasting from March 7 to April 12, May 15 to July 22, and August 23 to September 5, 2008, in total, 120 days, more than 280 individuals of scientists, engineers, students, and aircrews from 28 different institutes and universities were involved in. A total of 26 airborne missions, about 110 hours were flown. Airborne sensors including microwave radiometers at L, K and Ka bands, imaging spectrometer, thermal imager, CCD and LIDAR were used. Ground measurements were carried out concurrently with the airborne and space-borne remote sensing at four scales, i.e., key experimental area, foci experimental area, experiment site and elementary sampling plot. A network of hydro meteorological and flux observations was established in the upper and middle reaches of the Heihe River Basin. The network was composed of 12 super Automatic Meteorological Stations (AMS), 6 Eddy Covariance (EC) systems, 2 Large Aperture Scintillometers (LAS), and plenty of China Meteorological Administration (CMA) operational meteorological and hydrological stations. Additionally, we also used ground-based remote sensing instruments, such as Doppler Radar, ground based microwave radiometer and truck-mounted scatterometer and lots of auto

    Full Text Available INTRODUCTION: Publications are often used as a measure of success in research work. Chagas disease occurs in Central and Southern America. However, during the past years, the disease has been occurring outside Latin America due to migration from endemic zones. This article describes a bibliometric review of the literature on Chagas disease research indexed in PubMed during a 70-year period. METHODS: Medline was used via the PubMed online service of the U.S. National Library of Medicine from 1940 to 2009. The search strategy was: Chagas disease [MeSH] OR Trypanosoma cruzi [MeSH]. RESULTS: A total of 13,989 references were retrieved. The number of publications increased steadily over time from 1,361 (1940-1969 to 5,430 (2000-2009 (coefficient of determination for linear fit, R²=0.910. Eight journals contained 25% of the Chagas disease literature. Of the publications, 64.2% came from endemic countries. Brazil was the predominant country (37%, followed by the United States (17.6% and Argentina (14%. The ranking in production changed when the number of publications was normalized by estimated cases of Chagas disease (Panama and Uruguay, population (Argentina and Uruguay, and gross domestic product (Bolivia and Brazil. CONCLUSIONS: Several Latin American countries, where the prevalence of T. cruzi infection was not very high, were the main producers of the Chagas disease literature, after adjusting for economic and population indexes. The countries with more estimated cases of Chagas disease produced less research on Chagas disease than some developed countries.

    In order to determine which areas of cancer screening are currently receiving greatest emphasis in different parts of the world a Medline search of the literature for the period 2000-2002 was performed, concentrating attention on research into all aspects of efforts for early detection of tumours, with especial attention to methodology, motivation (including awareness of utility in the general populace and in minority groups), and intervention (professional training and general education). Focus on the skin, lung, cervix, breast, ovary + endometrium, oral cavity-oesophagus, gastric, colorectal, kidney + urinary tract and prostate, demonstrated large numbers of journals to be publishing papers in the field, with 10, 33, 130, 53, 24, 21, 6, 81, 12 and 58, respectively, in the period investigated, the grand total being 259. The average numbers of papers/journal ranged from 1.0-2.4 with only 15-35% appearing in journals with wide coverage. With the exception of oral, oesophageal and gastric cancer screening, an approximately 50% contribution in all areas was made by scientists in the US, followed by Europe (31% overall,) Asia (11%) then Australasia, Central and South America and Africa (3%, 2% and 1%, respectively). Clear differences were evident with the organ regarding specific topics receiving attention, most publications concerning the lung, ovary and urological tract dealing with detection methods. With the cervix and colorectum this topic accounted for half of the papers with especial attention to the relative advantages of the PAP smear, HPV testing and direct visual acetic acid (DVA) in the one, and FOBT and endoscopy in the other. Another major focus was found to be minority attitudes to breast, prostate and cervical screening in the US, whereas only few papers were found dealing with practical intervention, targeting professionals or screenees to increase participation in screening programs. The present approach suggested a number of areas requiring more

    The Orbital Acceleration Research Experiment (OARE), an electrostatic accelerometer package with complete on-orbit calibration capabilities, was flown for the first time aboard the Space Shuttle on STS-40. This is also the first time an accelerometer package with nano-g sensitivity and a calibration facility has flown aboard the Space Shuttle. The instrument is designed to measure and record the Space Shuttle aerodynamic acceleration environment from the free molecule flow regime through the rarified flow transition into the hypersonic continuum regime. Because of its sensitivity, the OARE instrument defects aerodynamic behavior of the Space Shuttle while in low-earth orbit. A 2-hour orbital time period on day seven of the mission, when the crew was asleep and other spacecraft activities were at a minimum, was examined. During the flight, a 'trimmed-mean' filter was used to produce high quality, low frequency data which was successfully stored aboard the Space Shuttle in the OARE data storage system. Initial review of the data indicated that, although the expected precision was achieved, some equipment problems occurred resulting in uncertain accuracy. An acceleration model which includes aerodynamic, gravity-gradient, and rotational effects was constructed and compared with flight data. Examination of the model with the flight data shows the instrument to be sensitive to all major expected low frequency acceleration phenomena; however, some erratic instrument bias behavior persists in two axes. In these axes, the OARE data can be made to match a comprehensive atmospheric-aerodynamic model by making bias adjustments and slight linear corrections for drift. The other axis does not exhibit these difficulties and gives good agreement with the acceleration model.

    2010-01-01

    The objective of KYT2014 (Finnish Research Programme on Nuclear Waste Management), run by the Ministry of Employment and the Economy, is to ensure the sufficient and comprehensive availability of the nuclear technological expertise and other capabilities required by the authorities when comparing different nuclear waste management ways and implementation methods. Research required for the supervision of nuclear waste management falls under other public authority programmes, whereas that related to the planning, implementation and development of nuclear waste management falls under research programmes conducted by licensees as part of their nuclear waste management obligation. The Framework Programme for 2011-2014 was prepared by a working group appointed by the Ministry of Employment and the Economy. The contents of the KYT2014 Research Programme comprise key research subjects in terms of national expertise. These include new and alternative nuclear waste management technologies, research into the safety of nuclear waste management and sociological research related to the issue. Through these research programmes, the aim is to assemble extensive, coordinated safety research wholes, particularly with respect to research on the capacity of buffer and filler materials in final disposal, the long-term durability of the final disposal canister, and safety case. Traditional projects, whether lasting one or several years, are also suitable for the Research Programme. The KYT2014 research programme serves as a discussion and communication forum between authorities, organisations engaged in nuclear waste management and research institutions, creating the preconditions for utilising limited research resources. It also strives to ensure a diverse and interdisciplinary research team for research projects. Another aim is to help secure the continuous availability of essential national expertise, while promoting scientific and high-level competence, and enhancing general

    A tandem mass spectral database system consists of a library of reference spectra and a search program. State-of-the-art search programs show a high tolerance for variability in compound-specific fragmentation patterns produced by collision-induced decomposition and enable sensitive and specific 'identity search'. In this communication, performance characteristics of two search algorithms combined with the 'Wiley Registry of Tandem Mass Spectral Data, MSforID' (Wiley Registry MSMS, John Wiley and Sons, Hoboken, NJ, USA) were evaluated. The search algorithms tested were the MSMS search algorithm implemented in the NIST MS Search program 2.0g (NIST, Gaithersburg, MD, USA) and the MSforID algorithm (John Wiley and Sons, Hoboken, NJ, USA). Sample spectra were acquired on different instruments and, thus, covered a broad range of possible experimental conditions or were generated in silico. For each algorithm, more than 30,000 matches were performed. Statistical evaluation of the library search results revealed that principally both search algorithms can be combined with the Wiley Registry MSMS to create a reliable identification tool. It appears, however, that a higher degree of spectral similarity is necessary to obtain a correct match with the NIST MS Search program. This characteristic of the NIST MS Search program has a positive effect on specificity as it helps to avoid false positive matches (type I errors), but reduces sensitivity. Thus, particularly with sample spectra acquired on instruments differing in their setup from tandem-in-space type fragmentation, a comparably higher number of false negative matches (type II errors) were observed by searching the Wiley Registry MSMS.

    Based on the samples of 113,468 publications on environmental assessment (EA) from the past 20 years, we used a bibliometric analysis to study the literature in terms of trends of growth, subject categories and journals, international collaboration, geographic distribution of publications, and scientific research issues. By applying thresholds to network centralities, a core group of countries can be distinguished as part of the international collaboration network. A frequently used keywords analysis found that the priority in assessment would gradually change from project environmental impact assessment (EIA) to strategic environmental assessment (SEA). Decision-theoretic approaches (i.e., environmental indicator selection, life cycle assessment, etc.), along with new technologies and methods (i.e., the geographic information system and modeling) have been widely applied in the EA research field over the past 20 years. Hot spots such as “biodiversity” and “climate change” have been emphasized in current EA research, a trend that will likely continue in the future. The h-index has been used to evaluate the research quality among countries all over the world, while the improvement of developing countries' EA systems is becoming a popular research topic. Our study reveals patterns in scientific outputs and academic collaborations and serves as an alternative and innovative way of revealing global research trends in the EA research field

    Publication of scientific articles related to khat (Catha edulis) in peer-reviewed journals is considered a measure of research productivity. The principal objectives of this study were to quantify the research contribution related to khat at the global level, as well as to determine its relative growth rate, collaborative measures taken, productivity at the institutional level, and the most prolific journals publishing on the topic. On the basis of title words related to khat, publications were identified for all data in Scopus bibliographic database's history up to December 31, 2014. The research productivity for the top 10 countries was evaluated in relation to the population size and gross domestic product (GDP) in 2013. The criteria were met by 651documents published in 51 countries. The largest number of articles associated with khat was from the UK (15.2 %), followed by Yemen (10.3 %), the USA (9.7 %) and Ethiopia (9.1 %). Ethiopia, Yemen, and Kenya had the highest productivity of publications after standardization by population size and GDP. Furthermore, Yemen achieved the highest number of collaborations, by having researchers from 19 countries. Ethiopia followed, having researchers from 16 countries. This bibliometric study provides a demonstration for the worldwide research activity regarding khat. The number of articles related to khat has increased rapidly over the last 10 years. The present study is a good starting point to evaluate research activity in the field of khat. Although the data shows a promising increase in the research activity, the quantity of khat-related research is still too little compared to the massive use of khat in certain countries.

    Project Prakash is an organization that reverses congenital blindness in children and adolescents in rural India with the hypothesis that these children will be able to recover some of their vision even though their visual system did not develop normally. This hypothesis challenges the scientific dogma established by the Nobel-prize winning research of Hubel and Wiesel that the brain cannot adapt to visual input after being completely deprived of vision during the critical first few months and years of life. Dr. Pawan Sinha presented his work at the largest and most respected ophthalmological research meeting, the Association for Research in Vision and Ophthalmology (ARVO), in Fort Lauderdale, Florida, on May 4, 2011.

    Full Text Available Abstract The golden Islamic history cannot be completed without the mention of Spain which was a bright star. It became one of the great Muslim civilizations; reaching its summit with the Umayyad caliphate of the tenth century. The heartland of Muslim rule was Southern Spain or Andulus. Different eras of Muslim rule in Andulus have been described in this research with an aim to highlight their apex and glory they achieved and then a focus on the reasons of their downfall as well. A brief introduction of the rulers in all eras with their major achievements and immersion in evil habits that led to their downfall has been the prime focus of this research. It gives us various glimpses from the course of history to reflect upon Muslim rule in Spain from a new perspective

    This report contains a summary of research carried out in order to search for a substructure of quarks and leptons. Theoretical predictions valid for a large class of composite models suggest enhanced muon production in high energy lepton-induced reactions. A tentative analysis of some cosmic ray data indicates that the predictions of such models are in accordance with the data. In order to move towards the construction of satisfactory composite models, a study of gauge invariant effective actions and phase transitions in gauge theories was begun. 20 refs., 1 fig

    It was the late Chosun Dynasty and Daehan Empire era that Western Medicine has firstly been introduced to Korea, previously operating on a basis of Korean traditional medicine. Western Medicine has been introduced by American missionary and Japanese Imperialism. An introduction of Western Medicine made it feasible to proceed new type medical care including operation, leading to require a new form of medical facilities. In the beginning, new facilities were constructed by Japanese Imperialism. Other hand many of facilities including Severance Hospital were established by missionaries. First of all, Daehan Empire established and managed a modern type of medical facility named "Jejoongwon" in 1885 as a government institution hospital. The Red Cross Hospital built in 1889. Afterwards, Jejoongwon and the Red Cross Hospital were taken over to missionary hospital and Japanese Imperialism, respectively. Japanese Imperialists firstly have protected their nationals residing in Chosun but have proceeded care a few Chosun people to exploit medical treatment as a mean to advertise superiority of the Empire of Japan. The facility that has firstly been established and managed was Jeseang Hospital in Busan in 1877, leading to establish in Wonju, Wonsan, and Mokpo. Afterwards, Japan has organized "Donginhoi" as a civil invasion organization, leading for "Donginhoi" to established "Dongin Hospital" in Pyeongyang, Daegu, and Seoul. Since 1909, governmental leading medical facility named Jahye Hospital was established according to an imperial order, leading to establish 32 hospitals all over the nation. American missionaries have established and managed 28 hospitals started from Severance Hospital built in 1904. However, Chosun doctors started to having educated and opening up their own hospital since 1920, leading for many of medical facilities to be established, but most of them have taken different roles followed by 6.25 War and economic development period.

    The High Energy Theory Group at Syracuse conducted basic research in several areas of current interest. A great deal of progress was made in the understanding of systems with unusual topological properties. A variational formulation of the equations that govern spinning particles in general relativity was accomplished. Perturbative as well as nonperturbative properties (incorporated in an effective Lagrangian) of quantum chromodynamics aspects were investigated. The question concerning gauge fixing in non-Abelian gauge theories was studied. Several new phenomenological aspects of unified electroweak interactions were explored with the object of finding experimental tests for models other than the currently accepted Salam-Weinberg theory. A unified electroweak model based on the group [SU(2) x U(1)] x U'(1) was investigated to account for the repeated fermionic generations and to incorporate CP violations and explain the CP violation as well as the Cabibbo-like angles in terms of the quark masses. A unified theory for all interactions (with the exception of gravitational interactions) based on the group SU(5) x SU(5) was proposed. Finally, axially symmetric multi-instanton solutions were shown to be generated from a set of conformal mappings. The work performed is described briefly; references are given

    The objective of this study was to estimate the research productivity of different world regions in the field of Parasitology. Using the PubMed database we retrieved articles from journals included in the "Parasitology" category of the "Journal Citation Reports" database of the Institute for Scientific Information for the period 1995-2003. Research productivity was evaluated based on a methodology we developed and used in other bibliometric studies by analysing: (1) the total number of publications, (2) the mean impact factor of all papers, and (3) the product of the above two parameters, (4) the research productivity in relation to gross domestic product of each region, and (5) the research productivity in relation to gross national income per capita and population of each region. Data on the country of origin of the research was available for 18,110 out of 18,377 articles (98.6% of all articles from the included journals). Western Europe exceeds all world regions in research production for the period studied (34.8% of total articles), with USA ranking second (19.9%), and Latin America & the Caribbean ranking third (17.2%). The mean impact factor in articles published in Parasitology journals was highest for the USA (1.88). Oceania ranked first in research productivity when adjustments for both the gross national income per capita (GNIPC) and population were made. Eastern Europe almost tripled the production of articles from only 1.9% of total production in 1995 to 4.3% in 2003. Similarly, Latin America and the Caribbean and Asia doubled their production. However, the absolute and relative production by some developing areas, including Africa, is still very low, despite the fact that parasitic diseases are major public health problems in these areas. Our data suggest that more help should be provided by the developed nations to developing areas for improvement of the infrastructure of research.

    Full Text Available Abstract Background The objective of this study was to estimate the research productivity of different world regions in the field of Parasitology. Methods Using the PubMed database we retrieved articles from journals included in the "Parasitology" category of the "Journal Citation Reports" database of the Institute for Scientific Information for the period 1995–2003. Research productivity was evaluated based on a methodology we developed and used in other bibliometric studies by analysing: (1 the total number of publications, (2 the mean impact factor of all papers, and (3 the product of the above two parameters, (4 the research productivity in relation to gross domestic product of each region, and (5 the research productivity in relation to gross national income per capita and population of each region. Results Data on the country of origin of the research was available for 18,110 out of 18,377 articles (98.6% of all articles from the included journals. Western Europe exceeds all world regions in research production for the period studied (34.8% of total articles, with USA ranking second (19.9%, and Latin America & the Caribbean ranking third (17.2%. The mean impact factor in articles published in Parasitology journals was highest for the USA (1.88. Oceania ranked first in research productivity when adjustments for both the gross national income per capita (GNIPC and population were made. Eastern Europe almost tripled the production of articles from only 1.9% of total production in 1995 to 4.3% in 2003. Similarly, Latin America and the Caribbean and Asia doubled their production. However, the absolute and relative production by some developing areas, including Africa, is still very low, despite the fact that parasitic diseases are major public health problems in these areas. Conclusion Our data suggest that more help should be provided by the developed nations to developing areas for improvement of the infrastructure of research.

    This is the final report of 'research on the maximum utilization of PSR results' focused on linkage strategy of PSR with continued operation over design life of operating NPP. Study was mace mainly on the analysis of current status of continued operation over plant design life in foreign countries, analysis of domestic PSR implementation status and establishment of basic strategy for linking PSR with continued operation. The results of the study performed so far can be summarized as below, the recent worldwide trend of promoting efficiency of NPP operation is focused on life extension of the plants rather than building of new. Considering the fact that some developed countries have already implemented the plant life extension and not a few countries at least have invested a good amount of fund for R and D of plant life management, we can not disregard the owner's request for review of life extension application without any reasonable description. As a result of investigation and analysis for the current status of continued operation over plant design life in foreign countries, it is concluded that most countries tend to link PSR with continued operation over plant design life and the extended operation has already been implemented in some developed countries. From the point, it turned out to be more desirable to couple those two systems for continued operation over plant design life of Korean NPP. A less than 7 years left until the end of design life for the oldest NPP Kori unit 1, it is strongly recommended to establish institutional frame including a legal basis and regulatory guidelines for continued operation over plant design life before long. For the prioritization methods of corrective actions in consideration of safety significance of shortcomings picked up from PSR, some related systems are reviewed including IAEA guidelines, PSR implementation experience of UK and US prioritization system for GSI (Generic Safety Issue). Basic principles are

    The Cochrane Library databases are available via different interfaces; evidence in the literature, together with anecdotal evidence, shows interfaces perform differently. To ensure the quality of searches, a study was undertaken to systematically explore the functionality of interfaces. To demonstrate differences in functionality when searching the same databases across different interfaces; to discuss the implications this may have on searching; and in a wider context, to suggest a 'best match' for comparable searching. Detailed cross-comparisons of a selection of search functions including MeSH terms, free text, proximity operators and truncation were undertaken in databases accessed via CRD, Wiley and Ovid. Up to three terms per function were selected and analysed. Differences were identified in the way searches for MeSH headings are executed, which fields are searched, how proximity operators perform, the word order searched and where terms are searched. This adds to a body of evidence demonstrating a lack of consistency in searching across different interfaces. A 'best match' for comparable searching is suggested. Differences between interfaces offering the same database content can have implications for the success of a search, on user education, and on database evaluation and purchasing decisions. © 2014 The authors.

    Research and development activities of the Fusion Research and Development Center (Division of Thermonuclear Fusion Research and Division of Large Tokamak Development) from April 1979 to March 1980 are described. In Plasma physics research two experiments both related to radio-frequency power injection into tokamak plasmas are to be noted. One is the demonstration of current drive by lower hybrid waves in JFT-2 and the other high efficiency ICRF heating at two-ion hybrid resonance in JFT-2a/DIVA. A multi-MW neutral beam injection system was installed and tested at JFT-2 with heating experiments expected to start shortly. JFT-2a/DIVA was shutdown to make space for the injector. A new ingredient in this area is the initiation of dee plasma experiments in Doublet III at San Diego, USA by JAERI team under US-Japan cooperation agreement. Progress was rapid achieving all experimental objective planned for this period. Construction of JT-60 is in progress as planned. A Mukoyama site where JT-60 and other new facilities will be located was procured in October 1979, which was followed by the construction starts of JT-60 buildings. The completion of JT-60 is expected in fall 1984. The progressive brief summaries are presented in following topics; development of neutral beam and radiofrequency heating system for JT-60, installation of the cluster testing facility with NbTi field coils, and design of tritium handling facility.

The JT-60 tokamak machine was completed in April 1985 after a seven-year construction period, and the first plasma operation was achieved on April 8, 1985. Initial experiments with Joule-heated plasmas were performed for three months from April to June 1985 and confirmed tokamak discharges of sufficient plasma current and density as required for additional heating in the divertor configuration. In JFT-2M experiments on beam and ICRF heated plasmas, H-mode discharges with good confinement characteristics were achieved in open divertor configurations. The Doublet III device had been modified into D-III D with a large deeshaped cross-section. The first plasma was obtained in February 1986. The development of a numerical tokamak code TRITON-II was continued. Plasma-surface interaction studies and vacuum technology development were continued. In the study of plasma heating technology, programmable control of the neutral beam energy was demonstrated in a proto-type injector unit. Negative hydrogen ion beams of 25 keV, 0.1 A were extracted by using multiaperture extraction grid. Research was also carried out on improvements of RF coupling system with emphasis on RF breakdown phenomena in a pill box type ceramic window. In the development of superconducting magnets, generation of a 12T magnetic field was demonstrated by the Test Module Coils. The fabrication of the Demonstration Poloidal Coil was started. Preliminary tritium tests on JAERI's proto-type Pd-diffuser and ceramic electrolysis cell had been successfully carried out in the TSTA at LANL. The design study of the Fusion Experimental Reactor was continued. A wide range of scoping studies was also made to evaluate cost/benefits effects. INTOR design studies were concentrated on tokamak innovations. (J.P.N.)

    Electronic health records (EHRs) can provide valuable data for outcomes research. However, unlike administrative claims databases, EHRs lack eligibility tables or a standard way to define the benefit coverage period, which could lead to underreporting of healthcare utilization or outcomes, and could result in surveillance bias. We tested the effect of using a proxy eligibility period (eligibility proxy) when estimating a range of health resource utilization and outcomes parameters under varying degrees of missing encounter data. We applied an eligibility proxy to create a benchmark cohort of chronic obstructive pulmonary disease (COPD) patients with 12 months of follow-up, with the assumption of no missing encounter data. The benchmark cohort provided parameter estimates for comparison with 9,000 simulated datasets representing 10-90% of COPD patients (by 10th percentiles) with between 1 and 11 months of continuous missing data. Two analyses, one for datasets using an eligibility proxy and one for those without an eligibility proxy, were performed on the 9,000 datasets to assess estimator performance under increasing levels of missing data. Estimates for each study variable were compared with those from the benchmark dataset, and performance was evaluated using bias, percentage change, and root-mean-square error. The benchmark dataset contained 6,717 COPD patients, whereas the simulated datasets where the eligibility proxy was applied had between 671 and 6,045 patients depending on the percentage of missing data. Parameter estimates had better performance when an eligibility proxy based on the first and last month of observed activity was applied. This finding was consistent across a range of variables representing patient comorbidities, symptoms, outcomes, health resource utilization, and medications, regardless of the measures of performance used. Without the eligibility proxy, all evaluated parameters were consistently underestimated. In a large COPD patient

    1991-10-01

    R and D activities of the Naka Fusion Research Establishment, JAERI, are reported for the period from April 1, 1990 to March 31, 1991. Since the shutdown of JT-60 in November 1989, the reconstruction work of the JT-60 device was continued until the end of March 1991. In the JT-60 Upgrade, the poloidal field coils and vacuum vessel were renewed and the plasma current was planned to increase up to 6 MA with lower single null divertor. The divertor plates were designed to be toroidally continuous and to use high-heat-conduction C/C composite materials. Another objective of JT-60U is to facilitate tokamak experiments with deuterium as the working gas. In the JFT-2M program, a system for divertor bias experiments was brought into operation and initial experiments were started to study its effects on plasma discharges. Effects of ergodic magnetic limiter on H-modes were examined and stationary H-modes were obtained under the control of ergodic magnetic limiter currents. The DIII-D program was highlighted by the attainment of 11% beta with a double null divertor plasma. As for the fusion engineering research, development activities of the ceramic turbo-viscous pump and the surface insulation techniques for the tokamak in-vessel components are remarked in the vacuum technology area. In the high heat flux experiments with the JAERI Electron Beam Irradiation Stand (JEBIS), carbon-based materials and refractory metals were tested to evaluate surface erosion at plasma disruptions. The ITER Conceptual Design Activities, which began in April 1988 under the auspices of the IAEA, were successfully completed in December 1990. A lot of contributions to the program were made by JAERI people to support the design and R and D activities and to prepare a plan for the forthcoming Engineering Design Activities. (J.P.N.)

    1988-11-01

    Research and development activities of the Naka Fusion Research Establishment for the period of April 1987 to March 1988 are described. In JT-60, the plasma heating experiment aiming at a reactor-grade plasma was started in June 1987, after completing the integrated performance test of NBI and RF heating systems with the tokamak machine, most of the first wall being replaced to carbon tiles from titanium-carbide films. Enphasis was placed in the experiment on increasing the plasma current together with the optimization of plasma control and heating. The steady improvement of plasma performance lead finally in September reactor-grade plasma parameters, which were located inside the region depicted by the Atomic Energy Commission at the start of the JT-60 project. In JFT-2M and Doublet III-D, extensive experiments revealed detailed phenomenology of H-mode transition and its characteristics. The test of a prototype turbo molecular pump with a ceramic rotor driven by gas turbine was successfully completed. In the development of negative ion sources, steady improvement was made in the efficiency of negative ion formation and beam extraction. In the RF technology, test-fabricated 120 GHz gyrotron worked well. The Demo Poloidal Coil program was progressed as scheduled. The coils, two NbTi and one Nb 3 Sn, were under fabrication. The large cryogenic system was completed by sharing the JT-60 power supply. In the Tritium Process Laboratory, installation into glove boxes was completed in March 1988 of various experimental apparatus, i.e., fuel clean-up system, cryogenic distillation and thermal diffusion systsms for hydrogen isotope separation etc. In the reactor design study, recapitulation and review of FER design for last two years were made.

    Research and development activities at Naka Fusion Research Establishment, JAERI, are reported for the period from April 1, 1993 to March 31, 1994. The main objectives of JT-60U experiments in FY1993 were to achieve and sustain high confinement regime with current drive. The JFT-2M experiments progressed in the systematic study of the plasma responses by applying an external helical field and also in the study of the boundary plasma with electric field or current in the scrape off layer (SOL) introduced by the divertor bias system. The study in Plasma Theory and Computation focused on the ion temperature gradient instability, the linear toroidal particle simulation, the MHD stability and the analyses of burning plasma. The progresses on DIII-D experiments were obtained in the studies of divertor radiation, cryopumping and VH-mode plasma. As for the fusion engineering research, further developments of a ceramic vacuum pump and a high-resolution quadrupole mass spectrometer (QMS) were made. A high energy H - beam of 400keV and 0.18A was produced with a current density of 13mA/cm 2 for 1s. Many efforts were made in developing the long pulse gyrotron and the high efficiency collector potential depression (CPD) gyrotron in the radio-frequency (RF) technology area. The main progress in the Tritium Systems Test Assembly (under US/Japan collaboration) was to demonstrate the plasma exhaust stream under non-steady tokamak operation. Heating experiments of the development 1m long divertor module for ITER were performed at a heat flux of 15MW/m 2 for 30sec. The R and D of the reactor structure were focused on the major components such as non-circular bellows, fail-safe first wall, etc.. The R and D of the blanket technology were focussed on the box structure for ITER shielding blanket and the out-of-reactor testing of ITER breeding blanket. (J.P.N.)

High-βp H-mode performance obtained in March 1993 was highlighted, in particular, a world-record fusion-triple-product of 1.1 x 10 21 m -3 · s · keV, and record values for JT-60 of neutron yield rate of 5.6 x 10 16 s -1 , stored energy of 8.3 MJ, and H-factor of 3.6. The JFT-2M continued to study divertor biasing and ergodic limiter experiments, and disruption control by ECH. The study in Plasma Theory and Computation focused on scaling laws of the thermal energy confinement and the bootstrap current, the iron temperature gradient instability, the MHD stability, the rotation damping by external magnetic error field, and the burning plasma of D- 3 He fusion. As for the fusion engineering research, the vacuum technology advanced the development of a high resolution quadrupole mass spectrometer, etc. The super-conducting Demo Poloidal Coil achieved pulsed operation with 7 T in 0.5 s, and newly developed conductors made of Nb 3 Al and Nb 3 Sn showed 40 kA at 12 T and 82 kA at 13.6 T, respectively. A high energy H - beam of 350 kV, 0.17 A was produced with a current density of 10 mA/cm 2 . Much effort was made in developing the ECH gyrotron with an output power of 460 kW at 120 GHz for 100 ms. The main progress in the Tritium Systems Test Assembly (a US/Japan collaboration) was continuous loop run for 25 days. The developed plasma facing components posed no problem under a heat flux of 20 MW/m 2 for 30 s over 1000 thermal cycles. (J.P.N.)

    publishing and printing in Bjelovar was made by Adolf Kolesar whose printing outfit opened in 1885. Soon after the outfit opened for business, he started publishing the first newspaper bearing the title Tjednik bjelovarsko-križevački: newspaper for education, economy, social and public life. The first issue came out 1 November 1890, marking the beginning of the development of periodicals in Bjelovar and the District. Adolf Kolesar furnished the technical base for the onset of newspaper publishing in Bjelovar, but the major creators of the content of Tjednik were the long-standing members of the editorial board and reputed columnists, Professor Gustav Fleischer, and solicitor and politician Milan Rojc. Literature, so far published on this matter, stresses that Tjednik ranked among the best regional papers of its time. The paper started out by publishing only the news, curios, items of educational and didactic content, reviews, short stories, sports news and advertisements. Its ambition was to cover matters of interest and reach the readers of the entire Bjelovar-Križevci District, but it had no particular political ambitions. In 1907 the owner and the editorial board changed and the paper became a political bulletin for the Croatian-Serbian coalition, with greater emphasis on the state, political, communal, social and economic matters, important in the life of the District. The last issue came out 30 August 1919, after which date the name was changed to Demokratski glas and the publication became the bulletin for the Yugoslav Democratic Party. In 1924 the paper resumed the old name, Tjednik, but survived only a short time. The research for this paper was greatly impeded by a scantiness of sources, as there are only very few copies of Tjednik preserved in the State Archives and the Bjelovar Town Museum, whereas the Petar Preradović Library in Bjelovar does not own a single copy. Furthermore, there was the matter of reliability of the information found in literature, as it

    Research and development activities of the Naka Fusion Research Establishment for the period of April 1989 to March 1990 are reported. The experiment on JT-60 was continued to October 1989. In the pellet injection experiment, plasma energy confinement was improved and the maximum fusion product reached 1.2 x 10 20 m -3 s keV. The portion of the bootstrap current was up to 80% of the total plasma current in the high poloidal beta discharge. The fabrication of the new vacuum vessel and poloidal field coils for the JT-60 machine upgrade (JT-60U) have been made. The experiment to improve the confinement on JFT-2M was conducted. The ergodic magnetic limiter coils were installed. Quasi-steady-state H-mode discharge (10 sec at maximum) was achieved and a new high-beta regime with the improved Troyon coefficient have been explored in DIII-D. As for theoretical and computational studies, thermal instabilities of an edge plasma, plasma performance determined by the MHD instabilities and burning plasma problems were investigated. A new type of a vacuum pump--the ceramic turbo-viscous pump--has been developed. In the high heat flux technology, small-scale divertor samples are manufactured by means of brazing carbon fiber reinforced carbon composite to copper heat sinks. The thermal cycle tests show they endure against a heat flux up to 10MW/m 2 . As for the development of plasma heating technology, the 50 keV-10A negative hydrogen beam was extracted by means of seeding cesium in the ion plasma generator. 1.4 MW-10sec RF was generated from an improved electron gun in the modified 2GHz-range klystron. Nb 3 Sn superconducting coil with an inner diameter of 1.0 m was successfully magnetized up to 7 T in 1 sec. The gram-level tritium experiments were performed. Conceptual design of the International Thermonuclear Experimental Reactor (ITER) is proceeding under the auspices of the IAEA. Design study of the Fusion Experimental Reactor (FER) concept has been conducted. (J.P.N.)

    Full Text Available A bibliometric analysis based on Scopus database was performed to identify the global research trends related to Supported Ionic Liquid Membranes (SILMs during the time period from 1995 to 2015. This work tries to improve the understanding of the most relevant research topics and applications. The results from the analysis reveal that only after 2005 the research efforts focused on SILMs became significant, since the references found before that year are scarce. The most important research works on the four main application groups for SILMs defined in this work (carbon dioxide separation, other gas phase separations, pervaporation and liquid phase separations were summarized in this paper. Carbon dioxide separation appeared as the application that has received by far the most attention according to the research trends during the analysed period. Comments about other significant applications that are gaining attention, such as the employment of SILMs in analytical tasks or their consideration for the production of fuel cells, have been included.

    Full Text Available The history of the study of the Late Bronze Age and the Early Iron Age in the Volga-Kama region can be divided into four periods, characterized by research trends, specific methods, and forms. Their chronological framework is associated with milestone works of key importance by researchers who would discard the previous frame and give rise to new paradigms. The initial period of the studies of the Late Bronze Age and the Early Iron Age in the Volga-Kama area (the late 18th century to the early 1920s is discussed in the article. It started with first site discoveries and accumulation of materials, and completed with archaeological cultures identified and prehistoric archeology periodization formed. It was a period of activity of the Imperial Archaeological Society, which included studies in the Volga region. The tradition of holding Archaeological Congresses in Kazan was established. In the late 19th – early 20th centuries, the ancientries of the Volga-Kama region attracted the attention of Finnish archaeologists. The results of the initial period were summarized in the monographs by A. M. Tallgren that also formulated new challenges to researchers.

    Dragusin, M.

    2010-01-01

    The nuclear research reactor VVR-S was commissioned in July 1957. This reactor is in permanent shutdown since December 1997 and will be decommissioned. The duration of the decommissioning project is 11 years. The first year of decommissioning project is 2010. The spent nuclear fuels resulting from the 40 years of operating the nuclear research reactor are stored under wet conditions. The chemical and physical water parameters monitored are: transparency, conductibility, pH, chloride content, oxygen content, temperature, dry residual content, Al, Mn, Mg, Fe, Vn, Cr. Residual dry content must be maintained in requested range in order to prevent degradation and corrosion both of the clads, assemblies and linen material of the ponds. Two types of the nuclear fuel assemblies were used: LEU type -EK-10 and HEU type S-36 Russian origin. All spent nuclear fuel assemblies HEU-S-36 type were repatriated in Russian Federation in June 2009 in safety and security conditions without any problems due of the wet storage, after 25 years storage in wet conditions. The spent nuclear fuel assemblies types LEU EK-10 were stored in wet conditions more than 50 years. This paper describes the lessons learned during the 50 years management of the spent nuclear fuel resulted from the operation the research reactor VVR-S. The management was based on the maintenance of water parameters by water filtration, using at all times air HEPA filter incorporated in technological ventilation system and by monitoring the level, temperature, physical and chemical parameters of the water storage from ponds and by controlling ponds linen physical integrity. Also we have used the discs having the same compositions with materials from assemblies stored in the same ponds, in order to verify degradation and corrosion phenomena induced due to the quality of storage water. The paper will described these results obtained by metallographic, visual, XRF analysis onto discs and dry residual samples from storage

    AIMS--To assess the prevalence and degree of periodic acid Schiff (PAS) positivity in blast cells from children with lymphoblastic leukaemia (ALL); its association with other disease characteristics; and its clinical importance in predicting the outcome of treatment. METHODS--Marrow slides from entrants to a large United Kingdom multicentre ALL trial (UKALL X) were batch processed and assessed blind for PAS positivity by one morphologist. Patients were classified into groups A, B, and C, corresponding to less than 1% PAS positive cells, 1-10%, and over 10%, respectively. Their PAS pattern was then compared with other clinical and pathological features of ALL and with treatment outcome. RESULTS--Slides from 921 children were examined of which 371 (40%) were categorised as group A, 324 (35%) as group B, and 226 (25%) as group C. There was a clear association between the presence of blast cell vacuoles on Romanowsky staining and PAS positivity. Group A (PAS negative) patients included a disproportionate excess of those with L2 morphology, those under 2 or over 6 years of age, those with an initial white cell count over 50 x 10(9)/l, those with a T or null cell immunophenotype, and those with chromosomal abnormalities other than "high hyperdiploidy". Four years from diagnosis, group C patients had an 8% disease free survival advantage over those in group A (2p = 0.01). This was irrespective of initial white cell count, but not of immunophenotype or the presence of vacuoles. CONCLUSIONS--Strong PAS positivity is a feature of "common" ALL and is particularly associated with blast cell vacuoles. It does occasionally occur in other disease subtypes with or without vacuoles. It predicts a better response to current treatment, but not independently of other cell characteristics. Images PMID:7962616

  12. RESEARCHERS OF THE SOVIET PERIOD WHO STUDIED THE RAPPROCHEMENT OF THE PSYCHOLOGY OF THE UNCONSCIOUS AND THEOLOGY

    Directory of Open Access Journals (Sweden)

    David Damte

    2013-06-01

    Full Text Available The main theme of this article is the question of how it became possible to see a rapprochement between psychoanalysis and theology. At its beginnings, psychoanalysis was viewed as only psychological theory whose competence did not include the analysis of cultural problems and moral values. However, psychoanalysis continued to develop and concern itself with more and more aspects of the human condition including questions dealing with the psychological nature of religion. An important role in this process was played by the metapsychology of Freud and by psychoanalytical anthropology. It was possible on this basis to study the interaction of psychoanalysis and the various branches of philosophy, and finally the unprecedented rapprochement of psychoanalysis and theology, the latter of which found expression in the works of Pfi ster, Muller-Braunschweig, Jung, Niebuhr, Gerres, Rudin and Drewermann. Western researchers feel that besides the influence of metapsychology and anthropology, the rapprochement of psychoanalysis and theology owed a great deal to the concept of love which is considered a strong creative fundament by the authors mentioned above. Soviet researchers uncovered another side of this question. They held that an entire series of presuppositions of the psychoanalytical theory were based on a very general and often contradictory principle and admit various interpretations both drawn from philosophy as well as from theology. The author agrees with these Soviet specialists on the contradictory nature and generality of the principles of psychoanalysis and examines some concrete examples, particularly as regards the Freudian theory of the origin of religion and morality. The methodology used by the author may be defined as a comparative-historical method employing a descriptive and analytical approach

    The University of Pennsylvania elementary particle physics/particle cosmology group, funded by the Department of Energy Office of Science, participates in research in high energy physics and particle cosmology that addresses some of the most important unanswered questions in science. The research is divided into five areas. Energy Frontier - We participate in the study of proton-proton collisions at the Large Hadron Collider in Geneva, Switzerland using the ATLAS detector. The University of Pennsylvania group was responsible for the design, installation, and commissioning of the front-end electronics for the Transition Radiation Tracker (TRT) and plays the primary role in its maintenance and operation. We play an important role in the triggering of ATLAS, and we have made large contributions to the TRT performance and to the study and identification of electrons, photons, and taus. We have been actively involved in searches for the Higgs boson and for SUSY and other exotic particles. We have made significant contributions to measurement of Standard Model processes such as inclusive photon production and WW pair production. We also have participated significantly in R&D for upgrades to the ATLAS detector. Cosmic Frontier - The Dark Energy Survey (DES) telescope will be used to elucidate the nature of dark energy and the distribution of dark matter. Penn has played a leading role both in the use of weak gravitational lensing of distant galaxies and the discovery of large numbers of distant supernovae. The techniques and forecasts developed at Penn are also guiding the development of the proposed Large Synoptic Survey Telescope (LSST).We are also developing a new detector, MiniClean, to search for direct detection of dark matter particles. Intensity Frontier - We are participating in the design and R&D of detectors for the Long Baseline Neutrino Experiment (now DUNE), a new experiment to study the properties of neutrinos. Advanced Techology R&D - We have an extensive

  16. Collaborative project: research on strongly coupled plasmas. Final technical report for period July 15, 1998--July 14, 2002

    Energy Technology Data Exchange (ETDEWEB)

    Golden, Kenneth I.

    2002-09-16

    The main research accomplishments/findings of the project were the following: (1) Publication of an in-depth review article in Physics of Plasmas on the quasilocalized charge approximation (QLCA) in strongly coupled plasma physics and its application to a variety of Coulomb systems: the model one-component plasma in three and two dimensions, binary ionic mixtures, charged particle bilayers, and laboratory dusty plasmas. (2) In the strongly coupled Coulomb liquid phase, the physical basis of the QLCA, namely, the caging of particles trapped in slowly fluctuating local potential minima, is supported by molecular dynamics simulation of the classical three-dimensional one-component plasma. (3) The QLCA theory, when applied to the analysis of the collective modes in strongly coupled charged particle bilayers, predicts the existence of a remarkable long-wavelength energy gap in the out-of-phase excitation spectrum. More recent theoretical calculations based on the three principal frequency-moment sum rules reveal that the gap persists for arbitrary coupling strengths and over the entire classical to quantum domain all the way down to zero temperature. The existence of the energy gap has now been confirmed in a molecular dynamics simulation of the charged particle bilayer. (4) New compressibility and third-frequency-moment sum rules for multilayer plasmas were formulated and applied to the analysis of the dynamical structure function of charged particle bilayers and superlattices. (5) An equivalent of the Debye-Huckel weak coupling equilibrium theory for classical charged particle bilayer and superlattice plasmas was formulated. (6) The quadratic fluctuation-dissipation theorem (QFDT) for layered classical plasmas was formulated. (7) The QFDT was applied to a powerful kinetic theory-based description of the density-density response function and long-wavelength plasma mode behavior in strongly coupled two-dimensional Coulomb fluids in the weakly degenerate quantum domain.

  17. The Wiley Spinal Catheter-Over-Needle System for Continuous Spinal Anesthesia: A Case Series of 5 Cesarean Deliveries Complicated by Paresthesias and Headaches.

    McKenzie, Christine P; Carvalho, Brendan; Riley, Edward T

    2016-01-01

    Intrathecal catheter devices using a catheter-over-needle design and softer flexible material have been introduced to clinical practice with the aim of reducing some of the complications such as postdural puncture headaches and paresthesias seen with previous versions of intrathecal catheters. We present a case series of 5 cesarean deliveries using the Wiley Spinal intrathecal system (Epimed, Johnstown, New York), which was recently approved by the US Food and Drug Administration. The intrathecal catheter system consists of a flexible 23-gauge intrathecal cannula over a 27-gauge pencil-point spinal needle. The placement of the intrathecal catheter was successful in all 5 cases; however, paresthesias in 3 cases and postdural puncture headaches in 2 cases complicated the placement and use of the device. Although the unique catheter-over-needle design facilitates the use of smaller-gauge spinal needles for dural puncture and larger-gauge catheters for medication administration, this case series using the Wiley Spinal suggests that paresthesias and postdural puncture headaches may still limit its widespread utilization. Future studies are needed to determine the true incidence of complications and to determine the role of continuous spinal anesthesia in the obstetric population.

  20. [The Continuity Between World War II and the Postwar Period: Grant Distribution by the Japan Society for the Promotion of Science and the Subsidiary Fund for Scientific Research].

    Science.gov (United States)

    Mizusawa, Hikari

    2015-01-01

    This paper analyzes the distribution of the Subsidiary Fund for Scientific Research, a predecessor to the Grant-in-Aid for Scientific Research (KAKENHI), which operated in Japan from the 1930s to 1950s. It reveals that the Japanese government maintained this wide-ranging promotion system since its establishment during the war until well into the postwar period. Previous studies insist that, at the end of the war, the Japanese government generally only funded the research that it considered immediately and practically useful. In contrast to this general perception, my analysis illustrates that both before and after the war, funding was allotted to four research areas: natural science, engineering, agriculture, and medicine. In order to illuminate this continuity, I compare the Subsidiary Fund with another research fund existing from 1933 to 1947: the Grant of the Japan Society for the Promotion of Science (JSPS). The comparison demonstrates that the JSPS received externally raised capital from the military and munitions companies. However, while this group focused upon engineering and military-related research as the war dragged on, the Subsidiary Fund has consistently entrusted scientists with the authority to decide the allocation of financial support.

    2009-04-01

    In 2001, after 10 years' operation, Qinshan Nuclear Power Plant (Q1) started to carry out periodic safety review (PSR) based on a nuclear safety guideline, Periodic Safety Review for Operational Nuclear Power Plants (HAF0312), issued by National Nuclear Safety Administration of China (NNSA). Entrusted by the owner of Q1, Shanghai Nuclear Engineering Research and Design Institute (SNERDI) implemented reviews of three key safety factors including safety analysis, equipment qualification and ageing. PSR was a challenging work in China at that time and through three years' research and practice, SNERDI summarized a systematic achievement for the review including review methodology, scoping, review contents and implementation steps, etc.. During the process of review for the three safety factors, totally 148 review reports and 341 recommendations for corrections were submitted to Q1. These reports and recommendations have provided guidance for correction actions as follow-up of PSR. This paper focuses on technical aspects to carry out PSR for the above-mentioned three safety factors, including review scoping, contents, methodology and main steps. The review technology and relevant experience can be taken for reference for other NPPs to carry out PSR. (authors)

  2. Who theorizes age? The "socio-demographic variables" device and age-period-cohort analysis in the rhetoric of survey research.

    Science.gov (United States)

    Rughiniș, Cosima; Humă, Bogdana

    2015-12-01

    In this paper we argue that quantitative survey-based social research essentializes age, through specific rhetorical tools. We outline the device of 'socio-demographic variables' and we discuss its argumentative functions, looking at scientific survey-based analyses of adult scientific literacy, in the Public Understanding of Science research field. 'Socio-demographics' are virtually omnipresent in survey literature: they are, as a rule, used and discussed as bundles of independent variables, requiring little, if any, theoretical and measurement attention. 'Socio-demographics' are rhetorically effective through their common-sense richness of meaning and inferential power. We identify their main argumentation functions as 'structure building', 'pacification', and 'purification'. Socio-demographics are used to uphold causal vocabularies, supporting the transmutation of the descriptive statistical jargon of 'effects' and 'explained variance' into 'explanatory factors'. Age can also be studied statistically as a main variable of interest, through the age-period-cohort (APC) disambiguation technique. While this approach has generated interesting findings, it did not mitigate the reductionism that appears when treating age as a socio-demographic variable. By working with age as a 'socio-demographic variable', quantitative researchers convert it (inadvertently) into a quasi-biological feature, symmetrical, as regards analytical treatment, with pathogens in epidemiological research.

Not only was the teacher embedded in Dr. Grebmeier's research team efforts, but her students were able to follow the work on board through her daily journals and photos. Subsequently, Dr. Grebmeier traveled to Vermont for a personal visit to students in multiple classes, grades 4-12. The opportunity for teachers to be teamed with a researcher, especially over an extended period of time as we will discuss in our presentation, allows their students to share in the tremendous learning experience and gain a deeper understanding of the interdisciplinary nature of science. The result is that the students begin to understand how the content they learn in the classroom is utilized in a real world setting. We will also discuss the more subtle benefits that occurred throughout the school year through connecting academic content with personal examples of "real" science. Note that the recently released Next Generation Science Standards (NGSS), when fully implemented, will change the way students learn science. Appendix A of the NGSS lists 7 Conceptual Shifts in these new standards. #1 states "K-12 Science Education Should Reflect the Interconnected Nature of Science as it is Practiced and Experienced in the Real World" and #4 calls for a "Focus on Deeper Understanding of Content as well as Application of Content." What better way to address the standards than bringing real world science research into the classroom? Many K-12 science teachers, particularly those in elementary classrooms, have never had the opportunity to pursue their own research and even fewer have experienced first hand the real world work of a research scientist. This presentation will provide insights about our successful collaboration and value-added aspects to enhance the educational experience.

    Full Text Available Islamic architecture, a young field with a conservative scholarly lineage, has only recently begun to find its own theoretical bearings. After briefly reviewing the origins and formative stages of the field in the West, this article identifies a turning point brought about by the publication of Edward Saïd's seminal book Orientalism in 1978. It then introduces three critical notions, dynamic periodization, multiculturalism, and dialogue, which offer a framework for the study of Islamic architecture as a tradition with a solid historical selfconsciousness.

    Early life stress, such as childhood abuse, neglect and loss, is a well established major risk factor for developing depressive disorders later in life. We here summarize and discuss current developments in human research regarding the link between early life stress and depression. Specifically, we review the evidence for the existence of sensitive periods for the adverse effects of early life stress in humans. We further review the current state of knowledge regarding gene×environment (G×E) interactions in the effects of early life stress. While multiple genes operate in multiple environments to induce risk for depression after early life stress, these same genes also seem to enhance the beneficial effects of a positive early environment. Also, we discuss the epigenetic mechanisms that might underlie these G×E interactions. Finally, we discuss the potential importance of identifying sensitive time periods of opportunity, as well as G×E interactions and epigenetic mechanisms, for early interventions that might prevent or reverse the detrimental outcomes of early life stress and its transmission across generations.

  10. Induction period

    Land, C.E.; Tokunaga, M.

    1984-01-01

    Induction period is the temporal aspect of the excess cancer risk that follows an exposure to ionizing radiation. Operationally, it can be thought of as the time from an exposure of brief duration to the diagnosis of any resultant cancer. Whereas the magnitude of excess risk can be described by a single number, such as the average yearly excess risk over some fixed time interval after exposure, the temporal distribution requires a histogram or a curve, that is, an array or continuum of numbers. The study of induction period involves a search for a simple way of describing the temporal distribution of risk, that is, a way of describing a continuum by using only one or two numbers. In other words, the goal is to describe induction period probabilistically, using a parametric model with a few parameters

    Full Text Available The results of technological research of silk fabrics from the noble-born woman grave from Bolgar, which was made in the period of the Golden Horde are represented in the article. The burial has been found in the ruins of the mausoleum, which is dated from the end of the XIV century. The deviation from the Islamic traditions is regarded as peculiarity of this burial. There were found clothes from silk, which was decorated by golden threads and the temple rings. The object of study is a well-preserved complex headdress, which includes several textile layers, such kinds of the silk products of various kinds: shawls, scarves, veilings. That sort of headdress has analogues in ethnographic materials in Central Asia. Microscopy has been used to determine the species composition of the fabrics: there were considered the structure of textile weaves, technology for manufacturing threads, in polychrome fabrics - colour selection of the threads. The samples of medieval fabrics, such as lance, taffeta, summit and others have been identified. During the restoration of the veiling the method of stabilizing the object has been used, which combines the strengthening of the gold threads and plasticization of the archaeological fabrics. Golden embroidery pattern has been also recovered. The enhanced diversity indicates on developed trading system with various sources of imports - from China, Central Asia, Egypt.

    The periodic paralyses are a group of skeletal muscle channelopathies characterizeed by intermittent attacks of muscle weakness often associated with altered serum potassium levels. The underlying genetic defects include mutations in genes encoding the skeletal muscle calcium channel Ca v 1.1, sodium channel Na v 1.4, and potassium channels K ir 2.1, K ir 3.4, and possibly K ir 2.6. Our increasing knowledge of how mutant channels affect muscle excitability has resulted in better understanding of many clinical phenomena which have been known for decades and sheds light on some of the factors that trigger attacks. Insights into the pathophysiology are also leading to new therapeutic approaches. Copyright © 2018 Elsevier B.V. All rights reserved.

    The talk is concerned with the modelling of wave propagation in and vibration of periodic elastic structures. Although analysis of wave-guide properties of infinite periodic structures is a well establish research subject, some issues have not yet been fully addressed in the literature. The aim...... of the talk is to illustrate these issues in simple examples and to discuss possible applications and generalisations. First, the eigenfrequency spectra of finite periodic structures are compared with the location of stop-bands for their infinite counterparts for a hierarchy of four mathematical models....... In each case, special attention is paid to eigenfrequencies and eigenmodes of a single periodicity cell with appropriate boundary conditions. The influence of the amount of periodicity cells in a finite compound structure on its eigenfrequency spectrum is analyzed. Several features common...

    This report summarizes the activities of the INRA Water Research Consortium (IWRC) for the period beginning September 15, 2005 and ending December 16, 2010. This report compares accomplishments to project objectives, documents the activities associated with this project, and lists products developed during the course of the project. The Water Resources Research Needs Assessment team received funding from the Inland Northwest Research Alliance Water Resources Steering Committee to facilitate a structured needs assessment process that could provide a basis for future targeted research efforts to improve regional water resources management in the Inland Northwest region. The original INRA proposal specifically mentions the need to conduct a detailed assessment of the information and research needs of policy makers and water user groups during a period of increasing competition for scarce water supplies. A particular focus of this assessment would be to understand what types of research might facilitate water resource management during periods of drought. The specific goals of the Needs Assessment project were to: (1) Quickly ascertain the perceptions of diverse stakeholders in this region; (2) Condense this complex information into a format that can be shared with the INRA scientific panel, and (3) Develop of a realistic set of research needs & priorities that can shape future INRA-funded research activities.

    Tandem mass spectral libraries are versatile tools for small molecular identification finding application in forensic science, doping control, drug monitoring, food and environmental analysis, as well as metabolomics. Two important libraries are the 'Wiley Registry of Tandem Mass Spectral Data, MSforID' (Wiley Registry MSMS) and the collection of MS/MS spectra part of the 2011 edition of the 'NIST/NIH/EPA Mass Spectral Library' (NIST 11 MSMS). Herein, the sensitivity and robustness of the Wiley Registry MSMS were evaluated using spectra extracted from the NIST 11 MSMS library. The sample set was found to be heterogeneous in terms of mass spectral resolution, type of CID, as well as applied collision energies. Nevertheless, sensitive compound identification with a true positive identification rate ≥95% was possible using either the MSforID Search program or the NIST MS Search program 2.0g for matching. To rate the performance of the Wiley Registry MSMS, cross-validation experiments were repeated using subcollections of NIST 11 MSMS as reference library and spectra extracted from the Wiley Registry MSMS as positive controls. Unexpectedly, with both search algorithms tested, correct results were obtained in less than 88% of cases. We examined possible causes for the results of the cross validation study. The large number of precursor ions represented by a single tandem mass spectrum only was identified as the basic cause for the comparably lower sensitivity of the NIST library.

    Full Text Available BACKGROUND The postpartum period continues to be an important part of the tradition and culture among Indian women. But frequently the health of the postnatal women is neglected. So, the present study aimed to explore the beliefs and practices in the postpartum period regarding diet, rest, hygiene and confinement and assess association between cultural practices and socio demographic characteristics. METHODS A combined quantitative and qualitative study was carried out in the rural areas of Udupi district in Karnataka. Participants for the quantitative study were 110 women who had given birth in the past three months. This was followed by one focus group discussion (FGD among twelve consenting mothers at one of the rural health centers. RESULTS Among the 110 women, over 80% of women had increased their diet intake postpartum. Vegetables such as brinjal and fruits like papaya were avoided by 65.5% and 73.6% women respectively. Among the mothers 10.9% consumed less than 500 ml of water every day and 10% did not drink milk at all. Majority 94 (85% were aware of vulval and perineal hygiene. Household work was avoided by 56% of the women while 86.3% avoided going outdoors. Many women took home remedies for faster recuperation. These practices were influenced by the socioeconomic status and the woman’s educational status. CONCLUSION Traditional postpartum practices are still popular among women in rural Karnataka. It is critical to identify the harmful practices and reinforce the positive healthy practices to make postpartum period a healthy and joyful period for the mother.

    Various methods of the physics brought many informations on the nuclear elements which one can arrange some ponderable quantities, what is the case of the steady elements and some, unsteady elements, as most of natural radioelements. On the other hand, elements of shorter life duration, and notably those that are carried to an excited state, are more badly known, and one can get information to their consideration that by the mediator of the properties of the transitions that they undergo, when they give birth has best-known nuclear cash: among these transitions represent the isomeric transitions. The goal of this work is the survey of the isomeric transitions from metastable states of short period, included in the domain of the microsecond to some milliseconds. The method of the deferred coincidences has been put to the point and applied in this goal while using the advantages of the selectors to several channels, under two main aspects where the device to several channels was either a selector of time, either a selector of amplitudes. This method served to study the working of Geiger-Muller counter and to measure with precision the period of 181 Ta * in of the varied experimental conditions. The adopted value is 17,2 ±0,2 μs. This work also found an immediate practical application to the setting in evidence of very weak quantities of hafnium in zirconium, of which it constitutes a tenacious and difficult impurity to analyze by the ordinary ways.

  18. Sex and ancestry determine the free-running circadian period.

    The endogenous, free-running circadian period (τ) determines the phase relationship that an organism assumes when entrained to the 24-h day. We found a shorter circadian period in African Americans compared to non-Hispanic European Americans (24.07 versus 24.33 h). We speculate that a short circadian period, closer to 24 h, was advantageous to humans living around the equator, but when humans migrated North out of Africa, where the photoperiod changes with seasons, natural selection favoured people with longer circadian periods. Recently, in evolutionary terms, immigrants came from Europe and Africa to America ('the New World'). The Europeans were descendents of people who had lived in Europe for thousands of years with changing photoperiods (and presumably longer periods), whereas Africans had ancestors who had always lived around the equator (with shorter periods). It may have been advantageous to have a longer circadian period while living in Europe early in the evolution of humans. In our modern world, however, it is better to have a shorter period, because it helps make our circadian rhythms earlier, which is adaptive in our early-bird-dominated society. European American women had a shorter circadian period than men (24.24 versus 24.41), but there was no sex difference in African Americans (24.07 for both men and women). We speculate that selection pressures in Europe made men develop a slightly longer period than women to help them track dawn which could be useful for hunters, but less important for women as gatherers. © 2017 The Authors.

    Toxicology in Malaysia has experienced rapid development and made great progress in education and research in conjunction with economic development in Malaysia over the past two decades. The main objectives of this study were to analyse the research originating from Malaysia and published in toxicology journals and to examine the authorship pattern and the citations retrieved from the Scopus database. Data from 1 January 2003 till 31 December 2012 were searched for documents with specific words in the toxicology field as a 'source title' and Malaysia as an affiliation country. Research productivity was evaluated based on a methodology we developed and used in other bibliometric studies by analysing: (a) total and trends of contributions in toxicology fields between 2003 and 2012; (b) Malaysian authorship pattern and productivity; (c) collaboration patterns; (d) journals in which Malaysian researchers publish; (e) the classification of journals to Institute for Scientific Information (ISI) or non-ISI; (f) impact factors (IFs) of all publications; and (g) citations received by the publications. In total, 290 documents were retrieved from 55 international peer-reviewed toxicology journals. The quantity of publication increased by around 10-fold from 2003 to 2012. The h-index of the retrieved documents was 20. Of the 55 journal titles, 42 (76.4%) have their IF listed in the journal citation reports 2012. Forty-two documents (14.5%) were published in journals that had no official IF. The total number of citations, at the time of manuscript writing (5 August 2013), was 1707, with a median (interquartile range) of 3 (0-7). Malaysia collaborated mostly with countries in the Asia-Pacific regions (18.3%), especially India and Japan, followed by the Middle East and Africa (10.0%), especially Palestine and Yemen. The present data show a promising rise and a good start for toxicology research activity in Malaysia. The sharing of relevant research questions by developed and

    Full Text Available The objective of this study was to investigate the scientific production on the theme of youth and adults with intellectual disabilities, found in dissertations and theses in the period 1988 to 2008. For this, we carried out the survey on the bank of the CAPES, by searching with keywords specific to contemplate the education of youth and adults, special education, and intellectual disability and mental. We selected ten productions distributed in six Higher Education Institutions (HEI, the majority coming from public higher education institutions, for the Graduate Program in Education, and defended in the 2000s. Most studies focused on literacy and signaled the need for improvement of teaching practices, as well as the importance of the interaction of young people and adults with intellectual disabilities with their teachers. It was also found that there are few studies relevant to this population in question, pointing to a field of knowledge to be properly understood.

    Programs have been established at Florida A & M University to attract minority students to research careers in mathematics and computational science. The primary goal of the program was to increase the number of such students studying computational science via an interactive multimedia learning environment One mechanism used for meeting this goal was the development of educational modules. This academic year program established within the mathematics department at Florida A&M University, introduced students to computational science projects using high-performance computers. Additional activities were conducted during the summer, these included workshops, meetings, and lectures. Through the exposure provided by this program to scientific ideas and research in computational science, it is likely that their successful applications of tools from this interdisciplinary field will be high.

    1979-02-01

    Research and development works in fiscal year 1977 of the Division of Thermonuclear Fusion Research and the Division of Large Tokamak Development are described. 1) Theoretical studies on tokamak confinement have continued with more emphasis on computations. A task was started of developing a computer code system for mhd behavior of tokamak plasmas. 2) Experimental studies of lower hybrid heating up to 140 kW were made in JFT-2. The ion temperature was increased by 50% -- 60% near the plasma center. Plasma-wall interactions (particle and thermal fluxes to the wall, and titanium gettering) were studied. In JFT-2a (DIVA) ion sputtering, arcing and evaporation were identified, and the impurity ion sputtering was found to be a dominant origin of metal impurities in the present tokamaks. High temperature and high-density plasma divertor actions were demonstrated; i.e. the divertor decreases the radiation power loss by a factor of 3 and increases the energy confinement time by a factor of 2.5. Various diagnostic instruments operated sufficiently to provide useful information for the research with JFT-2 and JFT-2a(DIVA). 3) JFT-2 and JFT-2a(DIVA) operated as scheduled. Technological improvements were made such as titanium coating of the chamber wall, discharge cleaning and pre-ionization. 4) Detailed design of the prototype JT-60 neutral beam injector was made. A 200 kW, 650 MHz radiofrequency heating system for JFT-2 was completed; a lower hybrid heating experiment in JFT-2 was successful 5) In particle-surface interactions, the sputtering and surface erosion were studied. 6) Improvement designs of a superconducting cluster test facility and a test module coil were made in the toroidal coil development. 7) Second preliminary design of the tokamak experimental fusion reactor JXFR started in April 1977. Safety analyses were made of the main components and system of JXFR on the basis of the first preliminary design. (J.P.N.)

    Annual JRT-15 Target: Conduct experiments and analysis to quantify the impact of broadened current and pressure profiles on tokamak plasma confinement and stability. Broadened pressure profiles generally improve global stability but can also affect transport and confinement, while broadened current profiles can have both beneficial and adverse impacts on confinement and stability. This research will examine a variety of heating and current drive techniques in order to validate theoretical models of both the actuator performance and the transport and global stability response to varied heating and current drive deposition.

    Research concerned with the inspection of copper canisters for spent nuclear fuel by means of ultrasound carried out at Uppsala University in years 1994-2000 has been summarized in this report. Main goal of the project was demonstrating the feasibly of ultrasonic array technique for the inspection of canister welds and getting know-how needed for the successful application of this method in the future SKB's canister factory. The research work includes both the theoretical tasks, such as modeling of wave propagation, and the experimental tasks, like characterization and calibration of the ultrasonic system ALLIN. Important issues such as, material and grain noise characterization, processing ultrasonic signals, ultrasonic imaging, have also been addressed. The work included both developing new methods (for example, field modeling and transducer characterization) and applying known techniques (for instance, estimation of attenuation and velocity). Looking from the time perspective the whole project has been successful, which means that the main goal or at least its first part has been achieved. The array technique has been successfully used at SKB's Canister Lab and it has provided the users with pertinent information that was especially valuable during start up phase of the electron beam welding equipment. However, the second part of the goal, gathering the know-how, is unlimited by its nature and we intend to continue our efforts in this direction in the future. This means that we aim to develop methods that will refine the existing array technique by improving the detectability of defects and increasing the reliability of detection. This can be achieved through the improving ultrasonic imaging by using such techniques as, harmonic imaging, synthetic aperture focusing technique (SAFT) and deconvolution. Harmonic imaging has been already preliminarily investigated, the results were encouraging and this research will be continued. A preliminary study of

    Full Text Available Nitroxynil (NIT is a halogenated phenol used to control fascioliasis in cattle and sheep. The Commission Regulation EU No 37/2010 has established maximum residue limits for NIT in bovine and ovine muscle (400 μg kg−1, fat (200 μg kg−1, liver (20 μg kg−1 and kidney (400 μg kg−1, and more recently in bovine and ovine milk (20 μg kg−1. Thirty-five pregnant dairy cows were treated in this study with nitroxynil (340 mg/mL solution for injection at the recommended dose of 10 mg/kg body weight at the start of the dry period, i.e. 53 to 74 days before the expected calving. Calving occurred between 43 days and 79 days after treatment. The concentrations of NIT in the milk were monitored for up to 120 days after calving. NIT residues were extracted using acetonitrile; magnesium sulfate and sodium chloride were added to induce liquid-liquid partitioning and purified by dispersive solid phase extraction for clean-up. NIT was detected by ultra high performance liquid chromatography coupled to tandem mass spectrometry (UHPLC-MS/MS in negative ionization mode. The highest concentrations of this drug were found in two animals at the first milking, 48 and 53 day post treatment with levels of 362 and 657 μg kg–1, respectively. NIT residues were below the limit of detection of the method (0.24 μg/kg–1 between 67 and 106 day post-treatment. Following calving, residues rapidly depleted in animals and were non-detectable from 10 to 38 days post-calving. In particular, in all animals milk resulted compliant (<20 μg/kg−1 three days post partum.

    Research and development activities in the two divisions are closely related. 1) Theoretical and computational studies continued on tokamak confinement and heating related to experimental problems. Studies on NBI heating in JT-60 were completed. 2) Experimental studies on impurities, density control and effects of density fluctuations were made in JFT-2. Neutral beams up to 30 keV and 8 A were injected into JFT-2 plasma perpendicularly. The ion temperature was increased by 10% - 15%, which is in agreement with the prediction by classical Fokker-Planck theory. In JFT-2a(DIVA), plasma-wall interaction (behavior of heavy and light impurities) was studies. The divertor of DIVA reduced the plasma-wall interaction and hence the radiation loss due to heavy impurities by a factor of 3. A grazing-incidence vacuum monochromator was first used in impurity studies in JFT-2 and JFT-2a. 3) Technological improvements were made raising efficiencies of operation, maintenance and plasma research. 4) Neutral beam injector test stand ITS-2 of 100 keV was completed. Construction of a 200 kW, 650 MHz radiofrequency heating system for JFT-2 was started. 5) Sputterings of molybdenum and pyrolytic graphite by low-energy protons and chemical reaction rates of pyrolytic graphite with protons were measured. Honeycomb structure greatly reduced the sputtered particles. 6) The superconducting magnet development group made the design of cluster test apparatus and the development of large current superconductor. 7) Phase-I preliminary design of experimental fusion reactor JXFR was completed and preliminary safety evaluation of JXFR was made. 8) Detailed design of JT-60 was completed in November 1976. Engineering development contracts were all completed by March 1977. 9) Engineering studies and tests on critical components of JT-4 with non-circular plasma cross section and divertors were made, after the preliminary design in fiscal year 1975.

    Full Text Available La diseminación del conocimiento científico es un aspecto clave de la cultura y del desarrollo social. Estudiar las revistas especializadas puede arrojar luz acerca de importantes problemas, como los que impiden la edición de dichas publicaciones. Este estudio utiliza tres tipos de textos para, primero, identificar posibles causas de la falta de publicación de la revista especializada venezolana “Pedagogía” durante la década de 1980; segundo, conocer la coyuntura de la época en el contexto de producción de dicha revista y, tercero, señalar vías para evitar una nueva desaparición. Se analizaron editoriales entre los años 1971 y 2011, actas del Consejo de Escuela entre 1983 y 1989, así como respuestas a entrevistas semi-estructuradas a personajes claves, lo cual dio un total de 83 segmentos textuales. Tras el análisis de dichos segmentos, los resultados señalan como causas de desaparición a un complejo de factores agrupados bajo la categoría de “otros factores”, por encima de los económicos y los administrativos. El estudio perece develar creencias e ideologías de la comunidad universitaria en particular.

    comparison with models will provide important results over the next year or two. Many codes were improved in significant ways in order to model data under the challenging conditions of the pedestal. In addition, new and strengthened collaborations were established between experiment, modeling and theory, and these efforts include providing mechanisms for sharing experimental data. All of these efforts will continue to provide major benefits to future pedestal studies. Much of the experimental and modeling work performed to support this milestone is reported in detail in the research contributions to this report. Here, a summary of results from the various contributions, as they pertain to several proposed pedestal physics processes, is discussed here. Emphasis is placed on mechanisms for which there are results from one or more machines or one or more models. Work from preceding quarterly reports is used for some of this summary. At the end of this summary, a brief summary of implications for ITER and implications for future work will be presented.

    Full Text Available This review discusses Art is Not What You Think It Is, from the Wiley-Blackwell manifesto series. It focuses not only on the arguments about the presumed ideas about art – the sole maker of objects with unified content – but especially on the ‘art matrix’ that the authors propose to portray the shifting numerical and temporal elements linking makers and objects through forces of creation. The contribution of the authors is contrasted to the relative neglect of semiotics in art history and proposed as a good model to overcome apparent aporias in the field.

    In this article, we discuss some of the challenges encountered while conducting research in two maximum security prisons and approaches we found helpful to facilitate the research process through the development of collaborative relationships, the establishment of prison contacts, and the implementation of rigorous research methods. As a result of our experiences, we have been successful at maintaining a high rate of inmate participation (>80%) and a well-functioning multidisciplinary team. The approaches described may be useful to other investigators planning to conduct research in a challenging setting such as prisons. © 2012 Wiley Periodicals, Inc.

    In the period from 1984 to 1993 the Bavarian Project Group for Research into the Effects of Pollutants (PBWU), a division of the GSF Research Centre, coordinated research activities on forest damage on behalf of the Bavarian Ministry for Agriculture and Environment (StMLU). These activities comprised a total of approximately 80 research projects which were conducted by Bavarian reserach institutes. Most of the projects were dedicated to research into the effects of pollution. The complex interactions prevailing in forest ecosystems are reflected in the wide variety of research topics dealt with, which ranged form the determination of pollutant deposition, atmospheric chemistry, over biochemical and physiological mechanisms of pollutant uptake in tree to soil analyses taking fibrous roots and mycorrhiza into account. The field studies were conducted at the interdisciplinary research bases of the Bavarian forest damage research programme, among which the Wank research base plays an outstanding role. They were flanked by laboratory work and controlled experiments performed in the exposition chambers of the GSF. Even though numerous questions relating to material processes and to alterations in forest ecosystems remain to be solved, at lest in some research areas it is now possible to derive conclusive statements from the results of the conducted forest damage research. This report sums up the results obtained. (orig.)

    Spring and Autumn period, the vassal states began to carry out country defense construction actively, brought changes to building the ideological. At that time, the south region of Shandong, as an independent unit of geography, seldom affected by external factors, and had striking cultural characteristics. Vassal states there constructed their capital mainly to defense the neighboring countries and cope with small scale mergers war, not involving the nationwide military deployment. Therefore, the region reflect the construction thought changes during the Spring and Autumn Period, and consistent with the research purpose. Based on this judgment, the author analyzed each capital's location and terrain feature by topographic map. In brief, the Spring and Autumn Period, feudal states acted of one's own free will, the relationship between cities contained the one within and between vassal states. Within vassal state relationships included economic support, entrenching each other and protecting the country together. Meanwhile, strategic defensing, scrambling for resources and geographical location comprised of the competition between vassal states. In the agrarian age, the political centers and agricultural areas were interdependent, giving priority to the development of political cities. Transformation of capitals' space layout was actually the process of carving up farming plains, the powerful states occupy favorable geographical position, and the small countries would be encroached and annexed gradually.

  20. Periods and Nori motives

    CERN Document Server

    Huber, Annette

    2017-01-01

    This book casts the theory of periods of algebraic varieties in the natural setting of Madhav Nori’s abelian category of mixed motives. It develops Nori’s approach to mixed motives from scratch, thereby filling an important gap in the literature, and then explains the connection of mixed motives to periods, including a detailed account of the theory of period numbers in the sense of Kontsevich-Zagier and their structural properties. Period numbers are central to number theory and algebraic geometry, and also play an important role in other fields such as mathematical physics. There are long-standing conjectures about their transcendence properties, best understood in the language of cohomology of algebraic varieties or, more generally, motives. Readers of this book will discover that Nori’s unconditional construction of an abelian category of motives (over fields embeddable into the complex numbers) is particularly well suited for this purpose. Notably, Kontsevich's formal period algebra represents a to...

    In this paper we introduce the concept of super periodic potential (SPP) of arbitrary order n, n ∈I+, in one dimension. General theory of wave propagation through SPP of order n is presented and the reflection and transmission coefficients are derived in their closed analytical form by transfer matrix formulation. We present scattering features of super periodic rectangular potential and super periodic delta potential as special cases of SPP. It is found that the symmetric self-similarity is the special case of super periodicity. Thus by identifying a symmetric fractal potential as special cases of SPP, one can obtain the tunnelling amplitude for a particle from such fractal potential. By using the formalism of SPP we obtain the close form expression of tunnelling amplitude of a particle for general Cantor and Smith-Volterra-Cantor potentials.

    Ecology is often said to lack general theories sufficiently predictive for applications. Here, we examine the concept of a periodic table of niches and feasibility of niche classification schemes from functional trait and performance data. Niche differences and their influence on ecological patterns and processes could be revealed effectively by first performing data reduction/ordination analyses separately on matrices of trait and performance data compiled according to logical associations with five basic niche 'dimensions', or aspects: habitat, life history, trophic, defence and metabolic. Resultant patterns then are integrated to produce interpretable niche gradients, ordinations and classifications. Degree of scheme periodicity would depend on degrees of niche conservatism and convergence causing species clustering across multiple niche dimensions. We analysed a sample data set containing trait and performance data to contrast two approaches for producing niche schemes: species ordination within niche gradient space, and niche categorisation according to trait-value thresholds. Creation of niche schemes useful for advancing ecological knowledge and its applications will depend on research that produces functional trait and performance datasets directly related to niche dimensions along with criteria for data standardisation and quality. As larger databases are compiled, opportunities will emerge to explore new methods for data reduction, ordination and classification. © 2015 The Authors.

    The IAEA Safety Guide 50-SG-S8 devoted to 'Safety Aspects of Foundations of Nuclear Power Plants' indicates that operator of a NPP should establish a program for inspection of safe operation during construction, start-up and service life of the plant for obtaining data needed for estimating the life time of structures and components. At the same time the program should ensure that the safety margins are appropriate. Periodic safety analysis are an important part of the safety inspection program. Periodic safety reports is a method for testing the whole system or a part of the safety system following the precise criteria. Periodic safety analyses are not meant for qualification of the plant components. Separate analyses are devoted to: start-up, qualification of components and materials, and aging. All these analyses are described in this presentation. The last chapter describes the experience obtained for PWR-900 and PWR-1300 units from 1986-1989

    Following a recommendation by the International Union for Pure and Applied Chemistry (IUPAC), the groups of the periodic table shall be numbered from 1 to 18, instead of I to VIII as before. The recommendations has been approved of by the Committee on Nomenclature of the American Chemical Society. The new system abandons the distinction between main groups (a) and auxiliary groups (b), which in the past frequently has been the reason for misunderstandings between European and American chemists, due to different handling. The publishing house VCH Verlagsgesellschaft recently produced a new periodic table that shows the old and the new numbering system together at a glance, so that chemists will have time to get familiar with the new system. In addition the new periodic table represents an extensive data compilation arranged by elements. The front page lists the chemical properties of elements, the back page their physical properties.

    Full Text Available Abstract Background Reducing smoking in pregnancy is a policy priority in many countries and as a result there has been a rise in the development of services to help pregnant women to quit. A wide range of professionals are involved in providing these services, with midwives playing a particularly pivotal role. Understanding professionals’ experiences of providing smoking cessation support in pregnancy can help to inform the design of interventions as well as to improve routine care. Methods A synthesis of qualitative research of health professionals’ perceptions of the barriers and facilitators to providing smoking cessation advice to women in pregnancy and the post-partum period was conducted using meta-ethnography. Searches were undertaken from 1990 to January 2015 using terms for maternity health professionals and smoking cessation advisors, pregnancy, post-partum, smoking, and qualitative in seven electronic databases. The review was reported in accordance with the ‘Enhancing transparency in reporting the synthesis of qualitative research’ (ENTREQ statement. Results Eight studies reported in nine papers were included, reporting on the views of 190 health professionals/key informants, including 85 midwives and health visitors. The synthesis identified that both the professional role of participants and the organisational context in which they worked could act as either barriers or facilitators to an individual’s ability to provide smoking cessation support to pregnant or post-partum women. Underpinning these factors was an acknowledgment that the association between maternal smoking and social disadvantage was a considerable barrier to addressing and supporting smoking cessation Conclusions The review identifies a role for professional education, both pre-qualification and in continuing professional development that will enable individuals to provide smoking cessation support to pregnant women. Key to the success of this education

    2008-10-01

    Using data from a consecutive sample of 259 studies published in four leading nursing research journals in 2005-2006, we examined whether nurse researchers favor females as study participants. On average, 75.3% of study participants were female, and 38% of studies had all-female samples. The bias favoring female participants was statistically significant and persistent. The bias was observed regardless of funding source, methodological features, and other participant and researcher characteristics, with one exception: studies that had male investigators had more sex-balanced samples. When designing studies, nurse researchers need to pay close attention to who will benefit from their research and to whether they are leaving out a specific group about which there is a gap in knowledge.

    There is a well-documented shortage of physician researchers, and numerous training programs have been launched to facilitate development of new physician scientists. Short-term research training programs are the most practical form of research exposure for most medical students, and the summer between their first and second years of medical school is generally the longest period they can devote solely to research. The goal of short-term training programs is to whet the students' appetite for research and spark their interest in the field. Relatively little research has been done to test the effectiveness of short-term research training programs. In an effort to examine short-term effects of three different NIH-funded summer research training programs for medical students, we assessed the trainees' (N = 75) research self-efficacy prior to and after the programs using an 11-item scale. These hands-on training programs combined experiential, didactic, and mentoring elements. The students demonstrated a significant increase in their self-efficacy for research. Trainees' gender, ranking of their school, type of research, and specific content of research project did not predict improvement. Effect sizes for different types of items on the scale varied, with the largest gain seen in research methodology and communication of study findings. © 2013 Wiley Periodicals, Inc.

    We have synthesized monolithic particulate gels of periodic mesoporous silica by adding tetramethoxysilane to a homogeneous alkaline micellar precursor solution. The gels exhibit 5 characteristic length scales over 4 orders of magnitude: fractal domains larger than the particle size (>500 nm), particles that are {approximately}150 to 500 nm in diameter, interparticle pores that are on the order of the particle size, a feature in the gas adsorption measurements that indicates pores {approximately}10-50 nm, and periodic hexagonal arrays of {approximately}3 nm channels within each particle. The wet gel monoliths exhibit calculated densities as low as {approximately}0.02 g/cc; the dried and calcined gels have bulk densities that range from {approximately}0.3-0.5 g/cc. The materials possess large interparticle ({approximately}1.0-2.3 cc/g) and intraparticle ({approximately}0.6 cc/g) porosities.

    2013-11-01

    The Middle Period (AD 400-1000) in northern Chile's Atacama oases is characterized by an increase in social complexity and regional interaction, much of which was organized around the power and impact of the Tiwanaku polity. Despite the strong cultural influence of Tiwanaku and numerous other groups evident in interactions with Atacameños, the role of immigration into the oases during this period is unclear. While archaeological and bioarchaeological research in the region has shown no evidence that clearly indicates large groups of foreign immigrants, the contemporary increase in interregional exchange networks connecting the oases to other parts of the Andes suggests residential mobility and the possibility that movement of people both into and out of the oases accompanied these foreign influences. Here, we analyze biodistance through cranial non-metric traits in a skeletal sample from prehistoric San Pedro de Atacama to elucidate the extent of foreign influence in the oases and discuss its implications. We analyzed 715 individuals from the Middle Period (AD 400-1000) and later Regional Developments Period (AD 1000-1450), and found greater phenotypic differences between Middle Period cemeteries than among cemeteries in the subsequent period. We argue that this greater diversity extends beyond the relationship between the oases and the renowned Tiwanaku polity and reflects the role of the oases and its different ayllus as a node and way station for the Middle Period's myriad interregional networks.

    The authors present reasons why developmental psychologists should care about children's and adolescents' digital game play. These reasons may be identified as: a) digital game play is an integral aspect of children's and adolescents' lives; b) digital game play contributes to learning and cognitive development; and c) developmental research has the potential to contribute to effective educational game design. The authors expand on these reasons with the goal of introducing or reintroducing to developmental psychologists a rich and very relevant context in which to examine children's and adolescents' applied cognitive development.

    Despite community health centers' substantial role in local communities and in the broader safety-net healthcare system, very limited research has been conducted on community health center research experience, infrastructure, or needs from a national perspective. A national survey of 386 community health centers was conducted in 2011 and 2012 to assess research engagement among community health centers and their perceived needs, barriers, challenges, and facilitators with respect to their involvement in public health and health services research. This paper analyzes the differences between health centers that currently conduct or participate in research and health centers that have no prior research experience to determine whether prior research experience is indicative of different perceived challenges and research needs in community health center settings. © 2014 Wiley Periodicals, Inc.

    Manaus, a city of nearly two million people, represents an isolated urban area having a distinct urban pollution plume within the otherwise pristine Amazon Basin. The plume has high concentrations of oxides of nitrogen and sulfur, carbon monoxide, particle concentrations, and soot, among other pollutants. Critically, the distinct plume in the setting of the surrounding tropical rain forest serves as a natural laboratory to allow direct comparisons between periods of pollution influence to those of pristine conditions. The funded activity of this report is related to the Brazil-USA collaborative project during the two Intensive Operating Periods (wet season, 1 Feb - 31 Mar 2014; dry season, 15 Aug - 15 Oct 2014) of GoAmazon2014/5. The project addresses key science questions regarding the modification of the natural atmospheric chemistry and particle microphysics of the forest by present and future anthropogenic pollution.

    Han, Yingying; Zhang, Jun; Zhang, Wenxian

    2018-04-01

    Phenomena of electromagnetically induced transparency (PEIT) may be interpreted by the Autler-Townes Splitting (ATS), where the coupled states are split by the coupling laser field, or by the quantum destructive interference (QDI), where the atomic phases caused by the coupling laser and the probe laser field cancel. We propose modulated experiments to explore the PEIT in an alternative way by periodically modulating the coupling and the probe fields in a Λ-type three-level system initially in a dark state. Our analytical and numerical results rule out the ATS interpretation and show that the QDI interpretation is more appropriate for the modulated experiments. Interestingly, dark state persists in the double-modulation situation where control and probe fields never occur simultaneously, which is significant difference from the traditional dark state condition. The proposed experiments are readily implemented in atomic gases, artificial atoms in superconducting quantum devices, or three-level meta-atoms in meta-materials.

    Various methods of the physics brought many informations on the nuclear elements which one can arrange some ponderable quantities, what is the case of the steady elements and some, unsteady elements, as most of natural radioelements. On the other hand, elements of shorter life duration, and notably those that are carried to an excited state, are more badly known, and one can get information to their consideration that by the mediator of the properties of the transitions that they undergo, when they give birth has best-known nuclear cash: among these transitions represent the isomeric transitions. The goal of this work is the survey of the isomeric transitions from metastable states of short period, included in the domain of the microsecond to some milliseconds. The method of the deferred coincidences has been put to the point and applied in this goal while using the advantages of the selectors to several channels, under two main aspects where the device to several channels was either a selector of time, either a selector of amplitudes. This method served to study the working of Geiger-Muller counter and to measure with precision the period of {sup 181}Ta{sup *} in of the varied experimental conditions. The adopted value is 17,2 {+-}0,2 {mu}s.

    This review focuses on the so-called "periodic syndromes of childhood that are precursors to migraine", as included in the Second Edition of the International Classification of Headache Disorders. Three periodic syndromes of childhood are included in the Second Edition of the International Classification of Headache Disorders: abdominal migraine, cyclic vomiting syndrome and benign paroxysmal vertigo, and a fourth, benign paroxysmal torticollis is presented in the Appendix. The key clinical features of this group of disorders are the episodic pattern and intervals of complete health. Episodes of benign paroxysmal torticollis begin between 2 and 8 months of age. Attacks are characterized by an abnormal inclination and/or rotation of the head to one side, due to cervical dystonia. They usually resolve by 5 years. Benign paroxysmal vertigo presents as sudden attacks of vertigo, accompanied by inability to stand without support, and lasting seconds to minutes. Age at onset is between 2 and 4 years, and the symptoms disappear by the age of 5. Cyclic vomiting syndrome is characterized in young infants and children by repeated stereotyped episodes of pernicious vomiting, at times to the point of dehydration, and impacting quality of life. Mean age of onset is 5 years. Abdominal migraine remains a controversial issue and presents in childhood with repeated stereotyped episodes of unexplained abdominal pain, nausea and vomiting occurring in the absence of headache. Mean age of onset is 7 years. Both cyclic vomiting syndrome and abdominal migraine are noted for the absence of pathognomonic clinical features but also for the large number of other conditions to be considered in their differential diagnoses. Diagnostic criteria, such as those of the Second Edition of the International Classification of Headache Disorders and the North American Society for Pediatric Gastroenterology, Hepatology and Nutrition, have made diagnostic approach and management easier.

    Within its competence for energy research, the Bundesministerium fuer Wirtschaft und Technology (BMWi) (Federal Ministry of Economics and Technology) sponsors investigations into the safety of nuclear power plants. The objective of these investigations is to provide fundamental knowledge, procedures and methods to contribute to realistic safety assessments of nuclear installations, to the further development of safety technology and to make use of the potential of innovative safety-related approaches. The Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) mbH, by order of the BMWi, continuously issues information on the status of such investigations by publishing semi-annual and annual progress reports within the series of GRS-F-Fortschrittsberichte (GRS-F-Progress Reports). Each progress report represents a compilation of individual reports about the objectives, work performed, results achieved, next steps of the work etc. The individual reports are prepared in a standard form by the research organisations themselves as documentation of their progress in work and are published by the Research Management Division of GRS within the framework of general information on the progress in reactor safety research. The compilation of the reports is classified according to general topics related to reactor safety research. Further, use is made of the classification system 'Joint Safety Research Index' of the CEC (Commission of the European Communities). The reports are arranged in sequence of their project numbers. It has to be pointed out that the authors of the reports are responsible for the contents of this compilation. The BMWi does not take any responsibility for the correctness, exactness and completeness of the information nor for the observance of private claims of third parties. (orig.)

    Evaluation of partner relationships in menopausal period. A questionnaire study was performed in a group of 67 women (age: 45-55 years) and their partners. The inclusion criteria were: presence of climacteric symptoms, stable partnership, consent to research. 40 women and their spouses were included into the final study group. The investigative tool was based on 3 scales: Marriage Bond Scale (SWM); Scale of Attractiveness (SKAT); GREEN Scale evaluating intensification of menopausal symptoms and a set of additional questions concerning socio-demographical data, marital sexuality and substitute hormonal therapy. Mean age of respondents was 52 years. Most of the women demonstrated an amenorrhea (90%). Climacteric symptoms such as: hot flush, stress, depressive moods (87.5% each), musculoarticular pain (80%) occurred in various degree. 97.5% of women did not use a substitute hormonal treatment. The mean result of SWM for women and their partners scored 237 which is 79% of the total value. A correlation between exacerbation of menopausal signs and SWM score was not found. The co-attractiveness ratio counted on the basis of SKAT scale scored 30 points on average, which constitutes 74% of the maximum. Approximately 58% of the men accepted symptoms related to menopause in their partners; they tolerated changes appearing in the climacteric period, however; 100% of men did not talk about menopausal problems with their partners and did not support them in this difficult time. Men find their partners attractive in the perimenopausal period, accepting their partners and problems related to menopause.

    2007-03-01

    This study examines the population structure of Classic period (A.D. 250-900) Maya populations through analysis of odontometric variation of 827 skeletons from 12 archaeological sites in Mexico, Guatemala, Belize, and Honduras. The hypothesis that isolation by distance characterized Classic period Maya population structure is tested using Relethford and Blangero's (Hum Biol 62 (1990) 5-25) approach to R matrix analysis for quantitative traits. These results provide important biological data for understanding ancient Maya population history, particularly the effects of the competing Tikal and Calakmul hegemonies on patterns of lowland Maya site interaction. An overall F(ST) of 0.018 is found for the Maya area, indicating little among-group variation for the Classic Maya sites tested. Principal coordinates plots derived from the R matrix analysis show little regional patterning in the data, though the geographic outliers of Kaminaljuyu and a pooled Pacific Coast sample did not cluster with the lowland Maya sites. Mantel tests comparing the biological distance matrix to a geographic distance matrix found no association between genetic and geographic distance. In the Relethford-Blangero analysis, most sites possess negative or near-zero residuals, indicating minimal extraregional gene flow. The exceptions were Barton Ramie, Kaminaljuyu, and Seibal. A scaled R matrix analysis clarifies that genetic drift is a consideration for understanding Classic Maya population structure. All results indicate that isolation by distance does not describe Classic period Maya population structure. (c) 2006 Wiley-Liss, Inc.

    Manaus, a city of nearly two million people, represents an isolated urban area having a distinct urban pollution plume within the otherwise pristine Amazon Basin. The plume has high concentrations of oxides of nitrogen and sulfur, carbon monoxide, particle concentrations, and soot, among other pollutants. Critically, the distinct plume in the setting of the surrounding tropical rain forest serves as a natural laboratory to allow direct comparisons between periods of pollution influence to those of pristine conditions. The funded activity of this report is related to the Brazil-USA collaborative project during the two Intensive Operating Periods (wet season, 1 Feb - 31 Mar 2014; dry season, 15 Aug - 15 Oct 2014) of GoAmazon2014/5. The project addresses key science questions regarding the modification of the natural atmospheric chemistry and particle microphysics of the forest by present and future anthropogenic pollution. The first objective of the project was to understand and quantify the interactions of biogenic and anthropogenic emissions with respect to the production of secondary organic material. In clean conditions in the Amazon basin, secondary organic material dominates the diameter distribution of the submicron particles. How and why is the diameter distribution shifted by pollution? The second objective followed from the first in that, although the diameter distribution is dominated by secondary organic material, the actual source of new particle production remains uncertain (i.e., the number concentration). The second objective was to test the hypothesis that new particles under natural conditions are produced as a result of evaporation of primary particles emitted by fungal spores as well as to investigate any shifts in this mechanism under pollution conditions, e.g., in consequence to the high concentrations of SO2 in the pollution plume. Combined, the number-diameter distribution is the key connection to upscaling to the effects of aerosol

    The multiphoton ionization of hydrogen by a strong bichromatic microwave field is a complex process prototypical for atomic control research. Periodic orbit analysis captures this complexity: through the stability of periodic orbits we can match qualitatively the variation of experimental ionization rates with a control parameter, the relative phase between the two modes of the field. Moreover, an empirical formula reproduces quantum simulations to a high degree of accuracy. This quantitative agreement shows how short periodic orbits organize the dynamics in multiphoton ionization. (fast track communication)

    After a presentation of some characteristics of gas and electric power industries, and an overview of the process and consequences of the general trend of deregulation in these sectors, the author of this research proposes a contribution to the economic analysis of movements of vertical integration of large oil companies and groups in which downstream gas activities and power activities represent a small fraction of their activities. The objectives of this research were then to understand why oil companies are practising vertical integration on the gas sector, and how these oil companies proceed in terms of organisational means to perform this successful movement of vertical integration. The author addresses theoretical concepts as they are analysed in some theories of the firm. The studied questions are then addressed in the case of some major European oil companies through a detailed examination of all their operations related to the gas downstream activities and to electricity activities, and by examining the most used organisational modes for the implementation of such vertical integrations

    The purpose of this project is to clarify the possibility of new hydrogen energy as a future energy source. The new hydrogen energy is obtained from the excess heat generation phenomenon through the electrolysis of heavy water using palladium metal as an electrode. The excess heat measurements were conducted through the excess heat confirmation tests using a fuel cell-type electrolytic cell up to November 1997. As a result, it was found that the excess heat measured by the calibration method can not be measured by the flow calorimetric method. In order to investigate the possibility of systematic errors of the both methods, the sensitivity, accuracy and responsibility, and the conditions of the excess heat generation, research activities based on new facts from scientific information and fundamental research supporting projects have been mainly performed. Among these, were performed the excess heat measurement tests by the cataphoresis method, absorption tests by the high-pressure and high-temperature charging method, gas plasma loading, in-situ X-ray detection, and reactant detection tests using Au/Pd/PdO heterogeneous structural body. 5 refs., 59 figs., 9 tabs.

    Scientific research often fails to have relevance and impact because scientists do not engage policy makers and influencers in the process of identifying information needs and generating high priority questions. To address this scholarship-policy gap, we have developed a model of Strategic Science. This research approach involves working with policy makers and influencers to craft research questions that will answer important and timely policy-related questions. The goal is to create tighter links between research and policy and ensure findings are communicated efficiently to change agents best positioned to apply the research to policy debates. In this article, we lay out a model for Strategic Science and describe how this approach may help advance policy research and action for eating disorders. © 2017 Wiley Periodicals, Inc.

    Nonlinear classical dissipative systems present a rich phenomenology in their "route to chaos," including period doubling, i.e., the system evolves with a period which is twice that of the driving. However, typically the attractor of a periodically driven quantum open system evolves with a period which exactly matches that of the driving. Here, we analyze a periodically driven many-body open quantum system whose classical correspondent presents period doubling. We show that by studying the dynamical correlations, it is possible to show the occurrence of period doubling in the quantum (period-one) steady state. We also discuss that such systems are natural candidates for clean and intrinsically robust Floquet time crystals.

Objetiva-se apresentar os estudos realizados sobre a fluorose entre 1993 e 2006. O período 1993-2004 demarca o intervalo entre a 2ªe a 3ª Conferência Nacional de Saúde Bucal. Em 2005-2006, a busca de dados primários apresentados em reuniões científicas confirmou os achados existentes na literatura, mostrando que a agenda científica brasileira não foi substancialmente influenciada pelas discussões travadas durante a 3ª Conferência. A maioria dos estudos concentra-se em áreas urbanas e a predominância no Brasil dos graus "muito leve" e "leve" de fluorose mostra não haver comprometimentos de ordem funcional. A baixa percepção da fluorose pela população, aliada à sua baixa prevalência, evoca o necessário debate sobre as questões de saúde coletiva no país. Visto que a produção científica nacional constitui uma importante fonte de conhecimentos para subsidiar a elaboração de políticas públicas para o setor da saúde, os sucessivos e pontuais estudos analisados mostram que, no que diz respeito à fluorose, o diagnóstico epidemiológico reafirma a necessidade, a importância e a segurança da fluoretação das águas de abastecimento público como medida de saúde coletiva.The epidemiology of dental fluorosis derives from surveys carried out in recent years, as a result of a better comprehension of metabolic aspects of fluoride in the human organism and oral health concerns.

    Periodization theory has, over the past seven decades, emerged as the preeminent training planning paradigm. The philosophical underpinnings of periodization theory can be traced back to the integration of diverse shaping influences, whereby coaching beliefs and traditions were blended with historically available scientific insights and contextualized against pervading social planning models. Since then, many dimensions of elite preparation have evolved significantly, as driven by a combination of coaching innovations and science-led advances in training theory, techniques, and technologies. These advances have been incorporated into the fabric of the pre-existing periodization planning framework, yet the philosophical assumptions underpinning periodization remain largely unchallenged and unchanged. One particularly influential academic sphere of study, the science of stress, particularly the work of Hans Selye, is repeatedly cited by theorists as a central pillar upon which periodization theory is founded. A fundamental assumption emanating from the early stress research is that physical stress is primarily a biologically mediated phenomenon: a presumption translated to athletic performance contexts as evidence that mechanical training stress directly regulates the magnitude of subsequent 'fitness' adaptations. Interestingly, however, since periodization theory first emerged, the science of stress has evolved extensively from its historical roots. This raises a fundamental question: if the original scientific platform upon which periodization theory was founded has disintegrated, should we critically re-evaluate conventional perspectives through an updated conceptual lens? Realigning periodization philosophy with contemporary stress theory thus presents us with an opportunity to recalibrate training planning models with both contemporary scientific insight and progressive coaching practice.

    The ultimate goal of the study is the improvement of predictive methods for safety analyses and design of advanced reactors for higher efficiency and enhanced safety and for deployable reactors for electrical power generation, process heat utilization and hydrogen generation. While key applications would be advanced gas-cooled reactors (AGCRs) using the closed Brayton cycle (CBC) for higher efficiency (such as the proposed Gas Turbine - Modular Helium Reactor (GT-MHR) of General Atomics [Neylan and Simon, 1996]), results of the proposed research should also be valuable in reactor systems with supercritical flow or superheated vapors, e.g., steam. Higher efficiency leads to lower cost/kwh and reduces life-cycle impacts of radioactive waste (by reducing waters/kwh). The outcome will also be useful for some space power and propulsion concepts and for some fusion reactor concepts as side benefits, but they are not the thrusts of the investigation. The objective of the project is to provide fundamental thermal fluid physics knowledge and measurements necessary for the development of the improved methods for the applications.

  1. Research Directed at Developing a Classical Theory to Describe Isotope Separation of Polyatomic Molecules Illuminated by Intense Infrared Radiation. Final Report for period May 7, 1979 to September 30, 1979; Extension December 31, 1997

    Lamb, W. E. Jr.

    This final report describes research on the theory of isotope separation produced by the illumination of polyatomic molecules by intense infrared laser radiation. This process is investigated by treating the molecule, sulfur hexafluoride, as a system of seven classical particles that obey the Newtonian equations of motion. A minicomputer is used to integrate these differential equations. The particles are acted on by interatomic forces, and by the time-dependent electric field of the laser. We have a very satisfactory expression for the interaction of the laser and the molecule which is compatible with infrared absorption and spectroscopic data. The interatomic potential is capable of improvement, and progress on this problem is still being made. We have made several computer runs of the dynamical behavior of the molecule using a reasonably good model for the interatomic force law. For the laser parameters chosen, we find that typically the molecule passes quickly through the resonance region into the quasi-continuum and even well into the real continuum before dissociation actually occurs. When viewed on a display terminal, the motions are exceedingly complex. As an aid to the visualization of the process, we have made a number of 16 mm movies depicting a three-dimensional representation of the motion of the seven particles. These show even more clearly the enormous complexity of the motions, and make clear the desirability of finding ways of characterizing the motion in simple ways without giving all of the numerical detail. One of the ways to do this is to introduce statistical parameters such as a temperature associated with the distribution of kinetic energies of the single particle. We have made such an analysis of our data runs, and have found favorable indications that such methods will prove useful in keeping track of the dynamical histories.

  5. Torpedo: topic periodicity discovery from text data

    2015-05-01

    Although history may not repeat itself, many human activities are inherently periodic, recurring daily, weekly, monthly, yearly or following some other periods. Such recurring activities may not repeat the same set of keywords, but they do share similar topics. Thus it is interesting to mine topic periodicity from text data instead of just looking at the temporal behavior of a single keyword/phrase. Some previous preliminary studies in this direction prespecify a periodic temporal template for each topic. In this paper, we remove this restriction and propose a simple yet effective framework Torpedo to mine periodic/recurrent patterns from text, such as news articles, search query logs, research papers, and web blogs. We first transform text data into topic-specific time series by a time dependent topic modeling module, where each of the time series characterizes the temporal behavior of a topic. Then we use time series techniques to detect periodicity. Hence we both obtain a clear view of how topics distribute over time and enable the automatic discovery of periods that are inherent in each topic. Theoretical and experimental analyses demonstrate the advantage of Torpedo over existing work.

    Sponsored research increasingly requires multiinstitutional collaboration. However, research contracting procedures have become more complicated and time consuming. The perinatal research units of two colocated healthcare systems sought to improve their research contracting processes. The Lean Process, a management practice that iteratively involves team members in root cause analyses and process improvement, was applied to the research contracting process, initially using Process Mapping and then developing Problem Solving Reports. Root cause analyses revealed that the longest delays were the individual contract legal negotiations. In addition, the "business entity" was the research support personnel of both healthcare systems whose "customers" were investigators attempting to conduct interinstitutional research. Development of mutually acceptable research contract templates and language, chain of custody templates, and process development and refinement formats decreased the Notice of Grant Award to Purchase Order time from a mean of 103.5 days in the year prior to Lean Process implementation to 45.8 days in the year after implementation (p = 0.004). The Lean Process can be applied to interinstitutional research contracting with significant improvement in contract implementation. © 2015 Wiley Periodicals, Inc.

  7. Nonparametric Inference for Periodic Sequences

    KAUST Repository

    Sun, Ying

    2012-02-01

    This article proposes a nonparametric method for estimating the period and values of a periodic sequence when the data are evenly spaced in time. The period is estimated by a "leave-out-one-cycle" version of cross-validation (CV) and complements the periodogram, a widely used tool for period estimation. The CV method is computationally simple and implicitly penalizes multiples of the smallest period, leading to a "virtually" consistent estimator of integer periods. This estimator is investigated both theoretically and by simulation.We also propose a nonparametric test of the null hypothesis that the data have constantmean against the alternative that the sequence of means is periodic. Finally, our methodology is demonstrated on three well-known time series: the sunspots and lynx trapping data, and the El Niño series of sea surface temperatures. © 2012 American Statistical Association and the American Society for Quality.

    Research on emotion and pain has burgeoned. We review the last decade's literature, focusing on links between emotional processes and persistent pain. Neurobiological research documents the neural processes that distinguish affective from sensory pain dimensions, link emotion and pain, and generate central nervous system pain sensitization. Psychological research demonstrates that greater pain is related to emotional stress and limited emotional awareness, expression, and processing. Social research shows the potential importance of emotional communication, empathy, attachment, and rejection. Emotions are integral to the conceptualization, assessment, and treatment of persistent pain. Research should clarify when to eliminate or attenuate negative emotions, and when to access, experience, and express them. Theory and practice should integrate emotion into cognitive-behavioral models of persistent pain. © 2011 Wiley Periodicals, Inc.

  9. Periodicity of DNA in exons

    Full Text Available Abstract Background The periodic pattern of DNA in exons is a known phenomenon. It was suggested that one of the initial causes of periodicity could be the universal (RNYnpattern (R = A or G, Y = C or U, N = any base of ancient RNA. Two major questions were addressed in this paper. Firstly, the cause of DNA periodicity, which was investigated by comparisons between real and simulated coding sequences. Secondly, quantification of DNA periodicity was made using an evolutionary algorithm, which was not previously used for such purposes. Results We have shown that simulated coding sequences, which were composed using codon usage frequencies only, demonstrate DNA periodicity very similar to the observed in real exons. It was also found that DNA periodicity disappears in the simulated sequences, when the frequencies of codons become equal. Frequencies of the nucleotides (and the dinucleotide AG at each location along phase 0 exons were calculated for C. elegans, D. melanogaster and H. sapiens. Two models were used to fit these data, with the key objective of describing periodicity. Both of the models showed that the best-fit curves closely matched the actual data points. The first dynamic period determination model consistently generated a value, which was very close to the period equal to 3 nucleotides. The second fixed period model, as expected, kept the period exactly equal to 3 and did not detract from its goodness of fit. Conclusions Conclusion can be drawn that DNA periodicity in exons is determined by codon usage frequencies. It is essential to differentiate between DNA periodicity itself, and the length of the period equal to 3. Periodicity itself is a result of certain combinations of codons with different frequencies typical for a species.

  11. Periodic instantons and scattering amplitudes

    International Nuclear Information System (INIS)

    Khlebnikov, S.Yu.; Rubakov, V.A.; Tinyakov, P.G.

    1991-04-01

    We discuss the role of periodic euclidean solutions with two turning points and zero winding number (periodic instantons) in instanton induced processes below the sphaleron energy E sph . We find that the periodic instantons describe certain multiparticle scattering events leading to the transitions between topologically distinct vacua. Both the semiclassical amplitudes and inital and final states of these transitions are determined by the periodic instantons. Furthermore, the corresponding probabilities are maximal among all states of given energy. We show that at E ≤ E sph , the periodic instantons can be approximated by infinite chains of ordinary instantons and anti-instantons, and they naturally emerge as deformations of the zero energy instanton. In the framework of 2d abelian Higgs model and 4d electroweak theory we show, however, that there is not obvious relation between periodic instantons and two-particle scattering amplitudes. (orig.)

    The purpose of this note is to explore the structure of singly periodic monopoles for different values of the size to period ratio. The transition between a chain of small monopoles and the approximately two dimensional chain of large monopoles takes us through a region with an unintuitive dependence on the periodic direction. The focus is mainly on the smooth SU(2) monopole of charge 2.

  13. Beware of the predatory science journal: A potential threat to the integrity of medical research.

    2017-09-01

    The issue of predatory journals has become increasingly more prevalent over the past decade, as the open-access model of publishing has gained prominence. Although the open-access model is well intentioned to increase accessibility of biomedical research, it is vulnerable to exploitation by those looking to corrupt medical academia and circumvent ethics and research standards. Predatory journals will achieve publication by either soliciting unsuspecting researchers who have legitimate research but fall victim to these predators or researchers looking to quickly publish their research without a thorough review process. Some features of predatory journals are a quick non-peer-review process, falsely listing or exaggerating the credibility of editorial board members, and either lack of or falsification of institutional affiliations and database listings. These predatory journals are a serious threat to the integrity of medical research, as they will infect the available literature with unsubstantiated articles, and allow low-quality research. A number of steps can be taken to prevent the spread and increase awareness of predatory publishers, and these must be done to maintain the integrity of medical academia. Clin.

    Insights from the study of literature can inform and clarify concepts to guide psychotherapy practice and research. The author offers instances from narrative fiction (Durrell's Alexandria Quartet) and poetry (Hopkins, Baudelaire) to illustrate how the formulation of experience in words that are evocative (vs. ordinary), original (vs. trite), and precise (vs. approximate) are able to capture attention, move the emotions, and challenge beliefs; and how linkages among experiences, vividly and precisely expressed, create and enhance narrative meaning-revealing the inherent relativity of individual meanings and the need to consider the aggregate of relevant perspectives in every interpersonal situation. © 2018 Wiley Periodicals, Inc.

    2012-03-01

    Previous research highlights barriers to clinical psychologists conducting research, but has rarely examined U.K. clinical psychologists. The study investigated U.K. clinical psychologists' self-reported research output and tested part of a theoretical model of factors influencing their intention to conduct research. Questionnaires were mailed to 1,300 U.K. clinical psychologists. Three hundred and seventy-four questionnaires were returned (29% response-rate). This study replicated in a U.K. sample the finding that the modal number of publications was zero, highlighted in a number of U.K. and U.S. studies. Research intention was bimodally distributed, and logistic regression classified 78% of cases successfully. Outcome expectations, perceived behavioral control and normative beliefs mediated between research training environment and intention. Further research should explore how research is negotiated in clinical roles, and this issue should be incorporated into prequalification training. © 2012 Wiley Periodicals, Inc.

    Unambiguous reporting of a study's compliance with ethical guidelines in anatomical research is imperative. As such, clear, universal, and uniform reporting guidelines for study ethics are essential. In 2016, the International Evidence-Based Anatomy Working group in collaboration with international partners established reporting guidelines for anatomical studies, the Anatomical Quality Assurance (AQUA) Checklist. In this elaboration of the AQUA Checklist, consensus guidelines for reporting study ethics in anatomical studies are provided with in the framework of the AQUA Checklist. The new guidelines are aimed to be applicable to research across the spectrum of the anatomical sciences, including studies on both living and deceased donors. The authors hope the established guidelines will improve ethical compliance and reporting in anatomical research. Clin.

From these results, the long-term [0, 1060] (time unit solutions, ranging from the Planck time to the age of the universe, are computed reliably and quickly with a parallel multiple-precision Taylor series (PMT scheme. The application of FPA to periodic systems can greatly reduce the computation time of long-term reliable simulations. This scheme provides an efficient way to generate reference solutions, against which long-term simulations using other schemes can be tested.

  2. Detecting periodicities with Gaussian processes

    Nicolas Durrande

    2016-04-01

    Full Text Available We consider the problem of detecting and quantifying the periodic component of a function given noise-corrupted observations of a limited number of input/output tuples. Our approach is based on Gaussian process regression, which provides a flexible non-parametric framework for modelling periodic data. We introduce a novel decomposition of the covariance function as the sum of periodic and aperiodic kernels. This decomposition allows for the creation of sub-models which capture the periodic nature of the signal and its complement. To quantify the periodicity of the signal, we derive a periodicity ratio which reflects the uncertainty in the fitted sub-models. Although the method can be applied to many kernels, we give a special emphasis to the Matérn family, from the expression of the reproducing kernel Hilbert space inner product to the implementation of the associated periodic kernels in a Gaussian process toolkit. The proposed method is illustrated by considering the detection of periodically expressed genes in the arabidopsis genome.

  8. Rationalization of Comet Halley's periods

    Belton, Michael J. S.

    1990-01-01

    The sense of long axis orientation of Comet Halley during the Vega 1 encounter must be reversed from that deduced by Sagdeev et al. (1986) in order to harmonize the comet nucleus' Vega/Giotto-observed orientations with periodicities extracted from time-series brightness data. It is also demonstrated that Vega/Giotto observations can be satisfied by either a 2.2- or 3.7-day long-axis free precession period. A novel Fourier algorithm is used to reanalyze five independent data sets; strong evidence is adduced for periods harmonically related to a 7.4-day period. The preferred candidate models for Halley's nuclear rotation are characterized by a long-axis precession period of 3.7 days.

  9. Incorporating Spectra Into Periodic Timing

    Science.gov (United States)

    Connors, Alanna; Hong, J.; Protopapas, P.; Kashyap, V.

    2011-09-01

    The Chandra surveys have resulted in a wealth of data on low-luminosity X-ray sources (Lx 1030-34 erg/s) of Galactic scales beyond the local solar neighborhood. Many of these are compact binaries, in particular, cataclysmic variables, often identified by their periodic X-ray variability and spectra. Hong et al. (2009, 2011) have used energy quantiles (Hong, Schlegel & Grindlay, 2004) as a fast, robust indicator of spectral hardness and absorption of the X-ray sources. Energy quantiles also enable a simple but effective illustration of spectral changes with phase in these periodic systems: e.g. absorption by the accreting material is understood to drive the periodic light-curves. An interesting question is how to best make use of the information encapsulated in the periodic change in energy spectrum, along with the periodic change in intensity, especially for cases of ambiguous period determination? And, how to do it computationally efficiently? A first approach is to do the period search in intensity, as is standard; and then use a criterion of spectral variation to verify possible periods. Huijse, Zegers & Protopapas (2011) recently demonstrated a powerful period estimation technique using information potential and correntropy embedded in the light curve. Similar quantities based on energies (or energy quantiles) of X-ray photons can serve as criteria of spectral variation. A different approach treats the spectrum variations and intensity variations completely independently, searching through period-space in each, and then combining the results. A more general method would include both at the same time, looking for statistically significant variations above what is expected for a constant (in intensity and spectrum).

    Anthropometric measurements of the lip and mouth are of great importance in clinical dysmorphology as well as reconstructive plastic surgery. In this study, the philtrum length (PhL) and intercommissural distance (ICmD) nomograms for Egyptian children in the mixed dentition period were established. A group of 1,338 Egyptian students in primary schools (735 boys and 603 girls) were included in the study. The students were at mixed dentition period and their ages ranged from 7 to 12 years. Anthropometric norms of PhL and ICmD were developed with significant sex difference in certain groups. A ratio between PhL and ICmD was developed. These data will help facilitate both objective and subjective evaluation of the lip and mouth for proper diagnosis of orofacial anomalies and variations as well as for ideal treatment plans. © 2018 Wiley Periodicals, Inc.

    Periodic magnetic structures (undulators) are widely used in accelerators to generate monochromatic undulator radiation (UR) in the range from far infrared to the hard X-ray region. Another periodic crystalline structure is used to produce quasimonochromatic polarized photon beams via the coherent bremsstrahlung mechanism (CBS). Due to such characteristics as monochromaticity, polarization and adjustability, these types of radiation is of large interest for applied and basic research of accelerator-emitted radiation. The book provides a detailed overview of the fundamental principles behind electromagnetic radiation emitted from accelerated charged particles (e.g. UR, CBS, radiation of fast electrons in Laser flash fields) as well as a unified description of relatively new radiation mechanisms which attracted great interest in recent years. This are the so-called polarization radiation excited by the Coulomb field of incident particles in periodic structures, parametric X-rays, resonant transition radiation a...

    Howcutt, Sarah J; Barnett, Anna L; Barbosa-Boucas, Sofia; Smith, Lesley A

    2018-04-01

    This discussion paper proposes a five-part theoretical framework to inform recruitment strategies. The framework is based on a marketing model of consumer decision-making. Respondents in surveys are typically healthier than non-respondents, which has an impact on the availability of information about those most in need. Previous research has identified response patterns, provided theories about why people participate in research and evaluated different recruitment strategies. Social marketing has been applied successfully to recruitment and promotes focus on the needs of the participant, but little attention has been paid to the periods before and after participant-researcher contact (during advertising and following completion of studies). We propose a new model which conceptualises participation as a decision involving motivation, perception of information, attitude formation, integration of intention and action and finally evaluation and sharing of experience. Discussion paper. This discussion paper presents a critical review. No literature was excluded on date and the included citations span the years 1981-2017. The proposed framework suggests that researchers could engage a broader demographic if they shape research design and advertising to perform functions that participants are seeking to achieve. The framework provides a novel and useful conceptualisation of recruitment which could help to inform public engagement in research design, researcher training and research policy. This framework challenges researchers to investigate the goals of the potential participants when designing a study's advertising and procedures. © 2017 John Wiley & Sons Ltd.

    2013-11-01

    The field of structural biology, whose aim is to elucidate the molecular and atomic structures of biological macromolecules, has long been at the forefront of biomedical sciences in adopting and developing computational research methods. Operating at the intersection between biophysics, biochemistry, and molecular biology, structural biology's growth into a foundational framework on which many concepts and findings of molecular biology are interpreted1 has depended largely on parallel advancements in computational tools and techniques. Without these computing advances, modern structural biology would likely have remained an exclusive pursuit practiced by few, and not become the widely practiced, foundational field it is today. As other areas of biomedical research increasingly embrace research computing techniques, the successes, failures and lessons of structural biology computing can serve as a useful guide to progress in other biomedically related research fields.

    Full Text Available The Croatian (Yugoslav Academy of Sciences and Arts was the first academy to elect D. I. Mendeleev as its honorary member (1882, whereas the periodic table of the elements has been taught regularly at the Zagreb University since 1888. The early interest of Croatian chemists in the periodic table should be attributed primarily to their pan-Slavic attitude, particularly as proof that Slavic people were able to produce "their own Newtons" (M.

Such enthusiastic views, however, did not help in analyzing the contribution of Mendeleev and other scientists to the discovery and development of the periodic table of the elements.

  2. Minimum period and the gap in periods of Cataclysmic binaries

    International Nuclear Information System (INIS)

    Paczynski, B.; Sienkiewicz, R.

    1983-01-01

    The 81 minute cutoff to the orbital periods of hydrogen-rich cataclysmic binaries is consistent with evolution of those systems being dominated by angular momentum losses due to gravitational radiation. Unfortunately, many uncertainties, mainly poorly known atmospheric opacities below 2000 K, make is physically impossible to verify the quadrupole formula for gravitational radiation by using the observed cutoff at 81 minutes. The upper boundary of the gap in orbital periods observed at about 3 hours is almost certainly due to enhanced angular momentum losses from cataclysmic binaries which have longer periods. The physical mechanism of those losses is not identified, but a possible importance of stellar winds is pointed out. The lower boundary of the gap may be explained with the oldest cataclysmic binaries, whose periods evolved past the minimum at 81 minutes and reached the value of 2 hours within about 12 x 10 9 years after the binary had formed. Those binaries should have secondary components of only 0.02 solar masses, and their periods could be used to estimate ages of the oldest cataclysmic stars, and presumably the age of Galaxy. An alternative explanation for the gap requires that binaries should be detached while crossing the gap. A possible mechanism for this phenomenon is discussed. It requires the secondary components to be about 0.2 solar masses in the binaries just below the gap

    Motivated by recent experiments on long-lived magnetoplasmons in the presence of a perpendicular magnetic field, we investigate the dynamical dielectric response function of graphene in contact with a substrate using the random phase approximation. We add a periodically modulated magnetic field within the graphene plane and address both the inter and intra Landau band magnetoplasmons. Verification of the predicted magnetic modulation effects is possible by experiments analogous to those for the zero gap limit. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA.

    2011-01-01

    Autonomic nervous system (ANS) activity has been linked repeatedly to children's socioemotional and behavioral adaptive functioning and development, yet the literature on how various indexes of ANS activity develop in childhood is sparse. We utilized latent growth modeling to investigate the development of respiratory sinus arrhythmia (RSA), an established index of parasympathetic nervous system (PNS), and preejection period (PEP), a marker of sympathetic nervous system (SNS) influence on the heart, in children aged 8-10 years. At age 8, 251 children (128 girls, 123 boys; 162 European American, 89 African American) participated. Longitudinal data were collected during two additional waves when children were 9 and 10 years of age, with a 1-year lag between each wave. Children's RSA and PEP exhibited significant stability over time. Marginally significant variability was found among children in how RSA changed over time (slope), but there was no significant interindividual variability in PEP changes over development. A conditional growth curve model (i.e., one with predictor variables) showed that initial levels of RSA and PEP and the slope of RSA over time were predicted by several demographic factors including the child's sex and race; RSA of European American children showed significant increases over time while African American children had higher initial RSA but no significant change over time. Findings extend basic knowledge in developmental biopsychology and have implications for research focusing on ANS measures as important predictors, moderators, and mediators of childhood adaptation. © 2010 Wiley Periodicals, Inc.

    Periodic testing forms a remarkable part of the regular work tasks of the shift crew. Testing is generally carried out beside the daily monitoring and control work. Even remarkable plant related differences may occur in the procedures and routines used in periodic testing. The goal is still always the same, to regularly ensure that the systems and equipment are in working order according to their design. This presentation studies with examples the execution and scope of periodic testing as well as the routines and procedures used in the testing in Loviisa power plant. The presentation is based on the testing procedures of Loviisa power plant and the aim is not to compare them to the procedures of other plants. The scope of periodic testing has increased and the routines and procedures have been developed as the operation experience has increased. The assessment of the need of periodic testing and the consideration of the practical execution possibilities should be a part of the plant's planning phase as a part of the planning process.

  7. Periodicity, the Canon and Sport

    Directory of Open Access Journals (Sweden)

    Thomas F. Scanlon

    2015-10-01

    Full Text Available The topic according to this title is admittedly a broad one, embracing two very general concepts of time and of the cultural valuation of artistic products. Both phenomena are, in the present view, largely constructed by their contemporary cultures, and given authority to a great extent from the prestige of the past. The antiquity of tradition brings with it a certain cachet. Even though there may be peripheral debates in any given society which question the specifics of periodization or canonicity, individuals generally accept the consensus designation of a sequence of historical periods and they accept a list of highly valued artistic works as canonical or authoritative. We will first examine some of the processes of periodization and of canon-formation, after which we will discuss some specific examples of how these processes have worked in the sport of two ancient cultures, namely Greece and Mesoamerica.

  8. Five period measures of longevity

    Directory of Open Access Journals (Sweden)

    John Bongaarts

    2005-11-01

    Full Text Available This study provides a summary of recently proposed alternatives period measures of "longevity" and assesses whether empirical differences between these measures are consistent with predictions from analytic studies. Particular attention is given to the tempo effect. Three of the five period measures are virtually equal to one another in a simulated population in which mortality follows a Gompertz model with a constant rate of improvement. Similar results are observed among females in Denmark, England and Wales and Sweden in the last quarter century. However, these three measures differ substantially from the conventional period life expectancy when mortality changes over time. These findings are consistent with theoretical analysis by Bongaarts and Feeney (2002, 2003, 2005 which demonstrated that this deviation is caused by a tempo effect whose size varies with the rate of change in mortality.

    2018-03-05

    Accurate lattice energies of organic crystals are important i.e. for the pharmaceutical industry. Periodic DFT calculations with atom-centered Gaussian basis functions with the Turbomole program are used to calculate lattice energies for several non-covalently bound organic molecular crystals. The accuracy and convergence of results with basis set size and k-space sampling from periodic calculations is evaluated for the two reference molecules benzoic acid and naphthalene. For the X23 benchmark set of small molecular crystals accurate lattice energies are obtained using the PBE-D3 functional. In particular for hydrogen-bonded systems, a sufficiently large basis set is required. The calculated lattice energy differences between enantiopure and racemic crystal forms for a prototype set of chiral molecules are in good agreement with experimental results and allow the rationalization and computer-aided design of chiral separation processes. © 2018 Wiley Periodicals, Inc. © 2018 Wiley Periodicals, Inc.

  11. Periodicity and repeatability in data

    Science.gov (United States)

    Southwood, D.

    Using magnetic data from the first two years in Saturn orbit, the basic periodicity of apparent is examined with the aim of elucidating the `cam' shaft model of Espinosa et al. (2003) identifying the nature of the `cam' and giving a definitive period for its rotation. An initial hypothesis, supported by the spectral analysis of analysis of the first 8 months in orbit Gianpieri et al. (2006), is made that the source of the period is linked to something inside the planet and therefore that the source inertia means that the period effectively does not change over the 2 years. Moreover one expects that the source phase is fixed. Using this approach, not only can the period identified by spectral analysis (647.1 + 0.6 min.) be verified but also by phase analysis between successive passes over the 2 years the period can be refined to 647.6 + 0.1 min. The signal itself is remarkably reproducible from pass to pass. It appears in all three components of the field and its polarisation is unambiguously not attributable to direct detection of an internal field. Not only does the signal not decay rapidly with distance from the planet, but although it has the m=1 symmetry of a tilted dipole, the field lines diverge from the planet indicating an exterior source. This feature led to the `cam' model. The polarisation and comparisons of passes with different latitude profiles show a surprising north-south symmetry in the azimuthal field. The absence of asymmetry with respect to the magnetic equator rules out a direct magnetospheric-ionospheric interaction source. Accordingly, it is proposed that the basic `cam' effect is generated by a single hemisphere anomaly which creates hemisphere to hemisphere field aligned currents. The existence of Saturn phase related anomaly appears to produce a basic asymmetry in the inner magnetosphere that sets the phase of both an inflowing and outflowing sector in a rotating circulation system.

    There is at the present time a need in accurate models to asess the availability of periodically tested stand-by systems. This paper shows how to improve the well known 'saw-tooth curve' model in order to take into account various reliability parameters. A model is developed to assess the pointwise and the mean availabilities of periodically tested stand-by systems. Exact and approxination formulae are given. In addition, the model developed herein leads to optimize the test interval in order to minimize the mean unavailability. A safety diesel in a nuclear power plant is given as an example

  15. Applying the community partnership approach to human biology research.

    Science.gov (United States)

    2015-01-01

    Contemporary human biology research employs a unique skillset for biocultural analysis. This skillset is highly appropriate for the study of health disparities because disparities result from the interaction of social and biological factors over one or more generations. Health disparities research almost always involves disadvantaged communities owing to the relationship between social position and health in stratified societies. Successful research with disadvantaged communities involves a specific approach, the community partnership model, which creates a relationship beneficial for researcher and community. Paramount is the need for trust between partners. With trust established, partners share research goals, agree on research methods and produce results of interest and importance to all partners. Results are shared with the community as they are developed; community partners also provide input on analyses and interpretation of findings. This article describes a partnership-based, 20 year relationship between community members of the Akwesasne Mohawk Nation and researchers at the University at Albany. As with many communities facing health disparity issues, research with Native Americans and indigenous peoples generally is inherently politicized. For Akwesasne, the contamination of their lands and waters is an environmental justice issue in which the community has faced unequal exposure to, and harm by environmental toxicants. As human biologists engage in more partnership-type research, it is important to understand the long term goals of the community and what is at stake so the research circle can be closed and 'helicopter' style research avoided. © 2014 Wiley Periodicals, Inc.

    Little is known about how investigators approach their research programs along the translational research continuum. Many consider the translational continuum to be linear, with research beginning at the bench and concluding with research at the bedside or in the community. We aimed to understand if translational investigators approach and view their research in this fashion. We conducted semistructured individual interviews with 16 graduates of the University of Pittsburgh's Multidisciplinary Clinical Research Scholars Program (KL2) in 2012. Our research revealed three characteristic models. The first model we called "linear" and represented the traditional approach. The second we called "holistic"; these investigators began with central research questions and sought to explore them in every direction of translation, not necessarily taking linear steps. The third model we called "technical"; in this model, investigators focused on a unique technology or methodology and applied it across multiple research contexts. This study found that there are multiple ways that translational investigators approach their research program. Better understanding of these models can help educators and mentors guide investigators so that they can be more productive in their clinical or translational research career. © 2014 Wiley Periodicals, Inc.

  17. Resonances in a periodically driven bosonic system

    Science.gov (United States)

    Quelle, Anton; Smith, Cristiane Morais

    2017-11-01

    Periodically driven systems are a common topic in modern physics. In optical lattices specifically, driving is at the origin of many interesting phenomena. However, energy is not conserved in driven systems, and under periodic driving, heating of a system is a real concern. In an effort to better understand this phenomenon, the heating of single-band systems has been studied, with a focus on disorder- and interaction-induced effects, such as many-body localization. Nevertheless, driven systems occur in a much wider context than this, leaving room for further research. Here, we fill this gap by studying a noninteracting model, characterized by discrete, periodically spaced energy levels that are unbounded from above. We couple these energy levels resonantly through a periodic drive, and discuss the heating dynamics of this system as a function of the driving protocol. In this way, we show that a combination of stimulated emission and absorption causes the presence of resonant stable states. This will serve to elucidate the conditions under which resonant driving causes heating in quantum systems.

The author maintains that the working style of the editors and publishers of specialized periodicals has a considerable impact on educational process as it reflects the main strategy, policy and innovational trends in educational sphere. The periodicals should set up the required level of modern pedagogical science and discuss its concepts and methodology.The author focuses on the relations between editors and authors, authors and readers, and publication requirements, while analyzing the experience of the best scientific periodicals. In his opinion, the scientific journals should be available and provide the media for discussions and mass debates on current situations and development prospects in educational sphere. The task of involving the various strata of educational society in creative pedagogical work can be solved by using the modern information technologies. 

  19. Epigenetic epidemiology: promises for public health research.

    Science.gov (United States)

    Bakulski, Kelly M; Fallin, M Daniele

    2014-04-01

    Epigenetic changes underlie developmental and age related biology. Promising epidemiologic research implicates epigenetics in disease risk and progression, and suggests epigenetic status depends on environmental risks as well as genetic predisposition. Epigenetics may represent a mechanistic link between environmental exposures, or genetics, and many common diseases, or may simply provide a quantitative biomarker for exposure or disease for areas of epidemiology currently lacking such measures. This great promise is balanced by issues related to study design, measurement tools, statistical methods, and biological interpretation that must be given careful consideration in an epidemiologic setting. This article describes the promises and challenges for epigenetic epidemiology, and suggests directions to advance this emerging area of molecular epidemiology.

  20. Periodic and quasiperiodic revivals in periodically driven interacting quantum systems

    Science.gov (United States)

    Luitz, David J.; Lazarides, Achilleas; Bar Lev, Yevgeny

    2018-01-01

    Recently it has been shown that interparticle interactions generically destroy dynamical localization in periodically driven systems, resulting in diffusive transport and heating. In this Rapid Communication we rigorously construct a family of interacting driven systems which are dynamically localized and effectively decoupled from the external driving potential. We show that these systems exhibit tunable periodic or quasiperiodic revivals of the many-body wave function and thus of all physical observables. By numerically examining spinless fermions on a one-dimensional lattice we show that the analytically obtained revivals of such systems remain stable for finite systems with open boundary conditions while having a finite lifetime in the presence of static spatial disorder. We find this lifetime to be inversely proportional to the disorder strength.

  1. Hyperkalemic periodic paralysis associated with multiple sleep onset REM periods.

    1999-12-15

    A 24-year-old man with sporadic hyperkalemic periodic paralysis (HPP) presented with moderate excessive daytime sleepiness and transitory episodes of weakness which occurred during and after sleep. Multiple sleep latency test (MSLT) demonstrated the presence of five sleep onset REM periods (SOREMPs) and a sleep latency of five minutes. Treatment with a diuretic which decreases serum potassium resolved all the clinical symtomps and a new MSLT showed the absence of SOREMPs and a sleep latency of 13.5 minutes. To our knowledge, the patient herein reported is the first case that associates sleep abnormalities and multiple SOREMPs with HPP. Furthermore, the present case suggests that SOREMPs may be explained by an increased extracellular potassium conductance related to HPP.

  5. Equivariant surgery theories and their periodicity properties

    CERN Document Server

    Dovermann, Karl Heinz

    1990-01-01

    The theory of surgery on manifolds has been generalized to categories of manifolds with group actions in several different ways. This book discusses some basic properties that such theories have in common. Special emphasis is placed on analogs of the fourfold periodicity theorems in ordinary surgery and the roles of standard general position hypotheses on the strata of manifolds with group actions. The contents of the book presuppose some familiarity with the basic ideas of surgery theory and transformation groups, but no previous knowledge of equivariant surgery is assumed. The book is designed to serve either as an introduction to equivariant surgery theory for advanced graduate students and researchers in related areas, or as an account of the authors' previously unpublished work on periodicity for specialists in surgery theory or transformation groups.

    The Eclipsing Binaries via Artificial Intelligence (EBAI) project (Prsa et al) generated solutions for eclipsing binaries in the Large Magellanic Cloud (LMC) as observed by the OGLE II project. Automatic clustering applied to the results highlighted that the LMC's long period (P>10d) detached (EA) binaries follow a linear relation in Period-I magnitude (Devinney et al). Subsequent analysis of OGLE II data for the Small Magellanic Cloud (SMC) has revealed a similar relationship. The present relation is distinct from the Period-K band linear relation for LMC MACHO Project (Alcock et al) EBs as found by Wood et al, and discussed by Soszynski et al and Derekas et al. The Period-K band relation is convincingly modeled by invoking one EB component at the Roche lobe, whereas EBs in the Period-I magnitude relation reported here show minimal proximity effects and they are significantly fainter. We show that the Period-I magnitude relation is not a selection effect and weigh alternatives for its evolutionary basis. We are grateful for the support of this research from NSF/RUI Grant AST-05-75042.

    CERN Document Server

    Boeyens, J C A

    2003-01-01

    It is demonstrated that all stable (non-radioactive) isotopes are formally interrelated as the products of systematically adding alpha particles to four elementary units. The region of stability against radioactive decay is shown to obey a general trend based on number theory and contains the periodic law of the elements as a special case. This general law restricts the number of what may be considered as natural elements to 100 and is based on a proton:neutron ratio that matches the golden ratio, characteristic of biological and crystal growth structures. Different forms of the periodic table inferred at other proton:neutron ratios indicate that the electronic configuration of atoms is variable and may be a function of environmental pressure. Cosmic consequences of this postulate are examined. (author)

    2002-11-01

    While demonstrating a classic conservation-of-energy problem to my AP Physics students, I became curious about the periodic motion that ensued for certain initial conditions. The original problem consists of releasing a mass at the end of a string from an initial position horizontal to the plane of a table. The string comes in contact with a peg some distance below the point where the string is attached at the top. One is asked to find what minimum fraction of the string's length should the peg be placed to have the mass complete a circle about the peg. However, when the mass is released from much lower heights, the system undergoes periodic motion that can be thought of as an interrupted pendulum.

  12. Mentoring K scholars: strategies to support research mentors.

    Burnham, Ellen L; Schiro, Stephanie; Fleming, Michael

    2011-06-01

    The goal of this paper is to present strategies utilized to support K scholar research mentors. K scholars are generally assistant professors who are close to developing independent research programs. Of all the various types of mentees, K scholars offer the greatest challenges, as well as the greatest rewards, for research mentors. To see one's mentee achieve independent PI status and become an established investigator is one of the great joys of being a research mentor. Research mentors for K scholars, however, may not directly benefit from their mentoring relationship, neither in terms of obtaining data to support their research program or laboratory, nor in assistance with grants or scientific papers. There is a pressing need for the research community to address the workload, institutional expectations, and reward system for research mentors. The dearth of research mentors and role models in clinical translational science parallels the decreasing number of physicians choosing careers in clinical research. While there is limited empirical information on the effectiveness of mentor support mechanisms, this white paper concludes that providing mentor support is critical to expanding the available pool of mentors, as well as providing training opportunities for K scholars. © 2011 Wiley Periodicals, Inc.

    Participatory action research (PAR) approaches harness collaborative partnerships to stimulate change in defined communities. The purpose of this article is to illustrate key methodological strategies used in the application of PAR methods in the particularly challenging environment of a hierarchical organization. A study designed to promote sustainable, insider-generated system-level changes in the provision of end-of-life (EOL) care in the restrictive setting of six state prisons is used as an exemplar of the application of three cardinal principles of PAR. First, development of a collaborative network with active partnership between outsider academic researchers and insider co-researchers began with careful attention to understanding the culture and processes of prisons and gaining the support of organizational leadership, using qualitative data gathering and trust-building. During the implementation phase, promoting co-ownership of change in EOL care through the co-construction of knowledge and systems to enhance sustainable change required carefully-orchestrated strategies to maximize the collaborative spirit of the project. Co-researchers were empowered to examine their worlds and capture opportunities for change using new leadership skills role-modeled by the research team. Third, their local knowledge of the barriers inherent in the contextual reality of prisons was translated into achievable system change by production of a toolkit of formalized and well-rehearsed change strategies that collaborative teams were empowered to enact within their hierarchical prison environment. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    The USNRC Office of Nuclear Regulatory Research has developed a program for nuclear plant aging research (NPAR) to achieve an understanding of nuclear plant aging, its potential effects on safety, and methods for its detection and mitigation, sufficient for addressing safety and regulatory issues and supporting regulatory decisions on issues. Specifically, the NRC has aggressive research and regulatory programs associated with aging effects on piping, steam generators, containments, structures, and electrical and mechanical systems and components. In addition to safety assessment for the original license period for nuclear power plants, this aging information will be extremely useful in providing technical bases for efficient and effective regulation associated with possible license extension. This paper discusses the major activities of USNRC sponsored aging research program and recommends an approach to manage and handle aging at nuclear power plants

    With a growing need for developing future physician scientists, identifying characteristics of medical students who are likely to benefit from research training programs is important. This study assessed if specific learning styles of medical students, participating in federally funded short-term research training programs, were associated with research self-efficacy, a potential predictor of research career success. Seventy-five first-year medical students from 28 medical schools, selected to participate in two competitive NIH-supported summer programs for research training in aging, completed rating scales to evaluate learning styles at baseline, and research self-efficacy before and after training. We examined associations of individual learning styles (visual-verbal, sequential-global, sensing-intuitive, and active-reflective) with students' gender, ranking of medical school, and research self-efficacy. Research self-efficacy improved significantly following the training programs. Students with a verbal learning style reported significantly greater research self-efficacy at baseline, while visual, sequential, and intuitive learners demonstrated significantly greater increases in research self-efficacy from baseline to posttraining. No significant relationships were found between learning styles and students' gender or ranking of their medical school. Assessments of learning styles may provide useful information to guide future training endeavors aimed at developing the next generation of physician-scientists. © 2014 Wiley Periodicals, Inc.

  19. Electromagnetic radiation of electrons in periodic structures

    International Nuclear Information System (INIS)

    Potylitsyn, Alexander Petrovich

    2011-01-01

    Periodic magnetic structures (undulators) are widely used in accelerators to generate monochromatic undulator radiation (UR) in the range from far infrared to the hard X-ray region. Another periodic crystalline structure is used to produce quasimonochromatic polarized photon beams via the coherent bremsstrahlung mechanism (CBS). Due to such characteristics as monochromaticity, polarization and adjustability, these types of radiation is of large interest for applied and basic research of accelerator-emitted radiation. The book provides a detailed overview of the fundamental principles behind electromagnetic radiation emitted from accelerated charged particles (e.g. UR, CBS, radiation of fast electrons in Laser flash fields) as well as a unified description of relatively new radiation mechanisms which attracted great interest in recent years. This are the so-called polarization radiation excited by the Coulomb field of incident particles in periodic structures, parametric X-rays, resonant transition radiation and the Smith-Purcell effect. Characteristics of such radiation sources and perspectives of their usage are discussed. The recent experimental results as well as their interpretation are presented. (orig.)

    A periodic permanent magnet (PPM) klystron has beam transport structures and RF cavity structures, each of which has permanent magnets placed substantially equidistant from a beam tunnel formed about the central axis, and which are also outside the extent of a cooling chamber. The RF cavity sections also have permanent magnets which are placed substantially equidistant from the beam tunnel, but which include an RF cavity coupling to the beam tunnel for enhancement of RF carried by an electron beam in the beam tunnel.

    Periodic nonlinearity is a systematic error limiting the accuracy of displacement measurements at the nanometer level. However, an interferometer with a displacement measurement accuracy of less than 1 nm is required in nanometrology and in fundamental scientific research. To meet this requirement, a generalized, periodic nonlinearity-reduced interferometer, based on three construction principles has been developed for straightness measurements. These three construction principles have resulted in an interferometer with a highly stable design with reduced periodic nonlinearity. Verifications by a straightness interferometer have demonstrated that the periodic nonlinearity was less than 40 pm. The results also demonstrate that the interferometer design is capable of subnanometer accuracy and is useful in nanometrology

    The precise mechanism(s) governing the phenomenon of AV nodal Wenckebach periodicity is not fully elucidated. Currently 2 hypotheses, the decremental conduction and the Rosenbluethian step-delay, are most frequently used. We have provided new evidence that, in addition, dual pathway (DPW) electrophysiology is directly involved in the manifestation of AV nodal Wenckebach phenomenon. AV nodal cellular action potentials (APs) were recorded from 6 rabbit AV node preparations during standard A1A2 and incremental pacing protocols. His electrogram alternans, a validated index of DPW electrophysiology, was used to monitor fast (FP) and slow (SP) pathway conduction. The data were collected in intact AV nodes, as well as after SP ablation. In all studied hearts the Wenckebach cycle started with FP propagation, followed by transition to SP until its ultimate block. During this process complex cellular APs were observed, with decremental foot formations reflecting the fading FP and second depolarizations produced by the SP. In addition, the AV node cells exhibited a progressive loss in maximal diastolic membrane potential (MDP) due to incomplete repolarization. The pause created with the blocked Wenckebach beat was associated with restoration of MDP and reinitiation of the conduction cycle via the FP wavefront. DPW electrophysiology is dynamically involved in the development of AV nodal Wenckebach periodicity. In the intact AV node, the cycle starts with FP that is progressively weakened and then replaced by SP propagation, until block occurs. AV nodal SP modification did not eliminate Wenckebach periodicity but strongly affected its paradigm. © 2011 Wiley Periodicals, Inc.

    Full Text Available Striae periodicity refers to the number of cross-striations between successive lines of Retzius in tooth enamel. A regular time dependency of striae periodicity, known as the circaseptan interval, has been proposed. Previous studies on striae periodicity have been carried out on both modern and early humans given its potential applications in forensic age estimations and anthropology. Nevertheless, research comparing striae periodicities across gender groups and populations in different geographical locations, particularly in Asia, is lacking. In this study, we compared the striae periodicities of Heilongjiang and Singaporean Chinese, as well as that of Singaporean Chinese males and females. Results showed that while the median striae periodicity counts of Heilongjiang Chinese and Singaporean Chinese teeth are both 7, Heilongjiang Chinese tend to have lower striae periodicity counts than Singaporean Chinese (p < 0.01. No significant gender difference was observed between the median striae periodicity of Singaporean Chinese Female and Singaporean Chinese Male teeth (p = 0.511. We concluded that the median striae periodicity may statistically differ with geographical location, but not gender, provided that ethnicity and geographical location are held constant. Further studies are required to examine the causes for variation in striae periodicities between geographical locations, as well as to verify the other bio-environmental determinants of striae periodicity.

    To determine the percentage of research projects funded by the National Health and Medical Research Council in the period 2000-2014 that aimed specifically to deliver health benefits to Australians living in rural and remote areas and to estimate the proportion of total funding this represented in 2005-2014. This is a retrospective analysis of publicly available datasets. National Health and Medical Research Council Rural and Remote Health Research 2000-2014. 'Australian Rural Health Research' was defined as: research that focussed on rural or remote Australia; that related to the National Health and Medical Research Council's research categories other than Basic Science; and aimed specifically to improve the health of Australians living in rural and remote areas. Grants meeting the inclusion criteria were grouped according to the National Health and Medical Research Council's categories and potential benefit. Funding totals were aggregated and compared to the total funding and Indigenous funding for the period 2005-2014. Of the 16 651 National Health and Medical Research Council-funded projects, 185 (1.1%) that commenced funding during the period 2000-2014 were defined as 'Australian Rural Health Research'. The funding for Australian Rural Health Research increased from 1.0% of the total in 2005 to 2.4% in 2014. A summary of the funding according to the National Health and Medical Research Council's research categories and potential benefit is presented. Addressing the health inequality experienced by rural and remote Australians is a stated aim of the Australian Government. While National Health and Medical Research Council funding for rural health research has increased over the past decade, at 2.4% by value, it appears very low given the extent of the health status and health service deficits faced by the 30% who live in rural Australia. © 2018 The Authors.

    Both natural and artificial small-scale swimmers may often self-propel in environments subject to complex geometrical constraints. While most past theoretical work on low-Reynolds number locomotion addressed idealised geometrical situations, not much is known on the motion of swimmers in heterogeneous environments. As a first theoretical model, we investigate numerically the behaviour of a single spherical micro-swimmer located in an infinite, periodic body-centred cubic lattice consisting of rigid inert spheres of the same size as the swimmer. Running a large number of simulations we uncover the phase diagram of possible trajectories as a function of the strength of the swimming actuation and the packing density of the lattice. We then use hydrodynamic theory to rationalise our computational results and show in particular how the far-field nature of the swimmer (pusher versus puller) governs even the behaviour at high volume fractions.

  9. A periodic table for cancer.

    2015-01-01

    Cancers exhibit differences in metastatic behavior and drug sensitivity that correlate with certain tumor-specific variables such as differentiation grade, growth rate/extent and molecular regulatory aberrations. In practice, patient management is based on the past results of clinical trials adjusted for these biomarkers. Here, it is proposed that treatment strategies could be fine-tuned upfront simply by quantifying tumorigenic spatial (cell growth) and temporal (genetic stability) control losses, as predicted by genetic defects of cell-cycle-regulatory gatekeeper and genome-stabilizing caretaker tumor suppressor genes, respectively. These differential quantifications of tumor dysfunction may in turn be used to create a tumor-specific 'periodic table' that guides rational formulation of survival-enhancing anticancer treatment strategies.

    The D-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in D dimensions. This rule together with an Aujbau Prinzip is applied to produce a D-dimensional periodic table. A model is developed to rationalize the ordering of the shells predicted by the generalized Madelung rule. This model is based on the introduction of a Hamiltonian, invariant under the q-deformed algebra U{sub q}(so(D)), that breaks down the SO(D + 1) dynamical symmetry of the hydrogen atom in D dimensions. The D = 2 case (Flatland) is investigated in some detail. It is shown that the neutral atoms and the (moderately) positive ions correspond to the values q = 0.8 and q = 1, respectively, of the deformation parameter q. 55 refs.

    White dwarf pulsators (ZZ Ceti variables) osub solar acccur in the extension of the radial pulsation envelope ionization instability strip to the observed luminosities of 3 x 10 -3 L sub solar according to van Horn. Investigations were underway to see if the driving mechanisms of hydrogen and helium ionization can cause radial pulsations as they do for the Cepheids, the RR Lyrae variables, and the delta Scuti variables. Masses used in this study are 0.60 and 0.75 M sub solar for T/sub e/ between 10,000 K and 14,000 K, the observed range in T/sub e/. Helium rich surface compositions like Y = 0.78,, Z = 0.02 as well as Y = 0.28, Z = 0.02 were used in spite of observations showing only hydrogen lines in the spectrum. The deep layers are pure carbon, and several transition compositions are included. The models show radial pulsation instabilities for many overtone modes at periods between about 0.3 and 3 seconds. The driving mechanism is mostly helium ionization at 40,000 and 150,000 K. The blue edge at about 14,000 K is probably due to the driving region becoming too shallow, and the red edge at 10,000 K is due to so much convection in the pulsation deriving region that no radiative luminosity is available for modulation by the γ and kappa effects. It is speculated that the very long observed periods (100 to 1000 sec) of ZZ Ceti variables are not due to nonradial pulsations, but are possibly aliases due to data undersampling. 4 references

    Erikson's comprehensive theory of human development has been empirically validated by personality researchers who have taken a status approach to the adult stages of the life cycle: Identity, Intimacy, Generativity, and Integrity. An understanding of these stages has implications for psychotherapy. Erikson's theory provides a descriptive language for where the individual stands currently within a psychosocial developmental context, where he/she might have gotten "stuck" in the past, and where she/he is heading in terms of developmental goals. This article attempts to link the empirical research on Erikson's developmental theory with an approach to therapeutic intervention that could be utilized by therapists from an array of therapeutic approaches. The authors, who are developmental, personality and clinical psychologists, illustrate the use of Eriksonian personality theory in psychotherapy by discussing case examples from their own psychotherapy practices. © 2012 Wiley Periodicals, Inc.

    Cancer cell lines have contributed immensely in understanding the complex physiology of cancers. They are excellent material for studies as they offer homogenous samples without individual variations and can be utilised with ease and flexibility. Also, the number of assays and end-points one can study is almost limitless; with the advantage of improvising, modifying or altering several variables and methods. Literally, a new dimension to cancer research has been achieved by the advent of 3Dimensional (3D) cell culture techniques. This approach increased many folds the ways in which cancer cell lines can be utilised for understanding complex cancer biology. 3D cell culture techniques are now the preferred way of using cancer cell lines to bridge the gap between the 'absolute in vitro' and 'true in vivo'. The aspects of cancer biology that 3D cell culture systems have contributed include morphology, microenvironment, gene and protein expression, invasion/migration/metastasis, angiogenesis, tumour metabolism and drug discovery, testing chemotherapeutic agents, adaptive responses and cancer stem cells. We present here, a comprehensive review on the applications of 3D cell culture systems for these aspects of cancers. J. Cell.

    Objective To characterize the phenotype of patients with symptoms of periodic paralysis (PP) and ryanodine receptor (RYR1) gene mutations. Methods Cases with a possible diagnosis of PP but additional clinicopathologic findings previously associated with RYR1-related disorders were referred for a tertiary neuromuscular clinical assessment in which they underwent detailed clinical evaluation, including neurophysiologic assessment, muscle biopsy, and muscle MRI. Genetic analysis with next-generation sequencing and/or targeted Sanger sequencing was performed. Results Three cases with episodic muscle paralysis or weakness and additional findings compatible with a RYR1-related myopathy were identified. The McManis test, used in the diagnosis of PP, was positive in 2 of 3 cases. Genetic analysis of known PP genes was negative. RYR1 analysis confirmed likely pathogenic variants in all 3 cases. Conclusions RYR1 mutations can cause late-onset atypical PP both with and without associated myopathy. Myalgia and cramps are prominent features. The McManis test may be a useful diagnostic tool to indicate RYR1-associated PP. We propose that clinicopathologic features suggestive of RYR1-related disorders should be sought in genetically undefined PP cases and that RYR1 gene testing be considered in those in whom mutations in SCN4A, CACNA1S, and KCNJ2 have already been excluded.

    In 1966, the social scientists of the Simulmatics Corporation arrived in Saigon. Tasked by the Pentagon with helping to pacify South Vietnam, they conducted political and social psychological research on Viet Cong defectors, government soldiers, and Vietnamese villagers. This essay argues that Simulmatics's work captures some of the ironies of Cold War social science: its tendency to mask militarization behind the rhetoric of peaceful nation-building, its blurring of data collection and intelligence gathering, and its ambitious dedication to revealing the unseen contents of hearts and minds while remaining ignorant of the historical, cultural, and linguistic contexts in which its subjects lived. © 2011 Wiley Periodicals, Inc.

    The Harvard Clinical and Translational Science Center ("Harvard Catalyst") Research Subject Advocacy (RSA) Program has reengineered subject advocacy, distributing the delivery of advocacy functions through a multi-institutional, central platform rather than vesting these roles and responsibilities in a single individual functioning as a subject advocate. The program is process-oriented and output-driven, drawing on the strengths of participating institutions to engage local stakeholders both in the protection of research subjects and in advocacy for subjects' rights. The program engages stakeholder communities in the collaborative development and distributed delivery of accessible and applicable educational programming and resources. The Harvard Catalyst RSA Program identifies, develops, and supports the sharing and distribution of expertise, education, and resources for the benefit of all institutions, with a particular focus on the frontline: research subjects, researchers, research coordinators, and research nurses. © 2014 Wiley Periodicals, Inc.

    2011-01-01

    People with intellectual disability (ID) have a long history of discrimination and stigmatization, and a more recent history of pride and self-advocacy. The early history suggests that people with ID are a vulnerable population and deserve special research protections as do some other groups; the disability rights movement of the late 20th century aligns people with ID more closely with the principle of autonomy that has guided clinical and research ethics for the last 40 years. In examining the history of people with ID and the prevailing framework of human subjects research protections in the United States, we conclude that people with ID do not require special protection in human subjects research. The protections that have already been put in place for all individuals, if conscientiously and effectively implemented, achieve the right balance between safeguarding the interest of human research subjects and empowering individuals who choose to do so to participate in research.

    Full Text Available Objective – To determine the impact of electronic journals on interlibrary loan (ILL activity. The hypothesis predicted that ILL requests would fall by approximately 10% during a four‐year period, that e‐journal use would increase by 10% per year and that there would be a correlation between the two.Design – Longitudinal data analysis of interlibrary loans over an eight year period from 1995 to 2003. The second part of the study is a retrospective data analysis of ejournal use from 2001‐2005.Setting – The 26 largest libraries in the state of Illinois, USA; all but the Chicago Public Library are academic institutions.Subjects –1. Journal article photocopy requests originating in the 26 libraries divided into three data sets: 1995/96, 1999/00 and 2002/03. 2. Electronic journal usage statistics from 25 libraries subscribing to packages within the EBSCOhost database for the fiscal years 2001‐2005.Methods –A retrospective analysis was conducted using interlibrary loan data for journal article photocopy requests either originating from or being satisfied by the 26 libraries in the study. It examined the data in three ways: the 26 libraries together, requests sent to libraries in the state of Illinois excluding the 26, and requests using libraries outside the state. The second part of the study examines usage data of electronic journals available in 25 of the 26 libraries.Main results – In the period from 1999 to 2003 a reduction in ILL requests of nearly 26% was observed within the participating 26 libraries. Analysis by broad subject discipline demonstrates that social sciences and sciences show the largest drop in requests – a 25% decrease from 1995‐2003. The number of requests from an individual journal title drops significantly in science by 34% within the state and by 37% for out‐of‐state requests.

    To establish the prevalence of Periodic Limb Movements during Sleep (PLMS) in patients with tetraplegia, controlling for obstructive sleep apnea. To explore whether demographic and injury characteristics affect PLMS. Retrospective cohorts. One hundred seventy-three participants with acute (12 months) tetraplegia who underwent full overnight diagnostic sleep studies. Two hundred sixty-two sleep study recordings were included. A randomly selected subgroup of 21 studies was assessed for PLM during wakefulness. Data were analysed according to the current American Academy of Sleep Medicine guidelines. Of the participants, 41.6% (43(15.7) years and 14.9% female) had a motor and sensory complete lesion. Sleep was poor with both OSA (87.8% with apnea hypopnoea index ≥ 5) and PLMS (58.4% with PLMS per hour PLMSI > 15) highly prevalent. There was no difference in the PLMSI between those with OSA (36.3(39.8)) or without (42.2(37.7), P = 0.42). PLMS were evident during REM and NREM sleep in all of the 153 patients with PLMSI > 15. All 21 participants in the subgroup of studies analysed for the PLM during quiet wakefulness, exhibited limb movements. None of the modelled variables (injury completeness, gender, OSA severity or time since injury) significantly predicted a PLMSI > 15 (P = 0.343). In conclusion, this study confirms the high prevalence of PLM in tetraplegia and the presence of leg movements in NREM and REM sleep along with wakefulness after controlling for OSA. No associations between the presence of PLMS and patient characteristics or injury specific aspects were found.

    Full Text Available The new scientific results should be published. However, the scientific result will be lost in inappropriate choice of the media in which is expected to appear. The world periodicals are developed in two levels, parts of the World System of Abstracting, Indexing and Evaluation, WSAIE. This system is just the body of the world science. The first level consists of the primary research journals. After careful inspection these journals should be accepted for covering in secondary research sources; the latter build the second level of the system. Journals, which are not presented in secondary research sources, are considered as marginal and the submission of manuscripts to such journals is not recommended. The second level of WSAIE has an elite part, an American one (Thomson Reuters, Web of Science, and an European one (Elsevier, SCOPUS. The journals of Web of Science are characterized by their impact factor, IF; the journals of SCOPUS are characterized by their im-pact rank, SJR; these journals' scientometric characteristics are entirely equal in use; no one of them should be favoured in respect to the other. However, these factors characterize the journals, not authors publishing in them; there-fore, these numbers cannot be used neither to compare different scientific areas nor in the personal evaluation of authors' scientific activity. The personal and institutional competencies for research could be estimated by properly use of some scientometric variables. The most important of them are considered. Amongst them are the index of Hirsch, h, and the factor of efficiency, e. In twenty-first century a new development of science began. The researchers should know the features of the contemporary science policy; otherwise the traps of the new time would compromise the effort of the researcher to achieve a success in his/her research activity.

    Over the last two decades, researchers have studied extensively the synthesis of mesostructured materials, which could be useful for drug delivery, catalytic cracking of petroleum, or reinforced plastics, among other applications. However, until very recently researchers used only temperature as a thermodynamic variable for synthesis, completely neglecting pressure. In this Account, we show how pressure can affect the synthetic chemistry of periodic mesoporous structures with desirable effects. In its simplest application, pressure can crystallize the pore walls of periodic mesoporous silicas, which are difficult to crystallize otherwise. The motivation for the synthesis of periodic mesoporous silica materials (with pore sizes from 2 to 50 nm) 20 years ago was to replace the microporous zeolites (which have pore sizes of amorphous nature of the mesoporous materials' channel walls. To address this problem, we developed the concept of "nanocasting at high pressure". Through this approach, we produced hitherto-unavailable, periodic mesostructured silicas with crystalline pore walls. In nanocasting, we compress a periodic mesostructured composite (e.g. a periodic mesoporous silica with carbon-filled pores) and subsequently heat it to induce the selective crystallization of one of the two phases. We attain the necessary high pressure for synthesis using piston-cylinder and multianvil apparatuses. Using periodic mesostructured silica/carbon nanocomposites as starting material, we have produced periodic mesoporous coesite and periodic mesoporous quartz. The quartz material is highly stable under harsh hydrothermal conditions (800°C in pure steam), verifying that crystallinity in the channel walls of periodic mesoporous silicas increases their hydrothermal stability.

    Among the priority next steps outlined during the first translational epilepsy research workshop in London, United Kingdom (2012), jointly organized by the American Epilepsy Society (AES) and the International League Against Epilepsy (ILAE), are the harmonization of research practices used in preclinical studies and the development of infrastructure that facilitates multicenter preclinical studies. The AES/ILAE Translational Task Force of the ILAE has been pursuing initiatives that advance these goals. In this supplement, we present the first reports of the working groups of the Task Force that aim to improve practices of performing rodent video-electroencephalography (vEEG) studies in experimental controls, generate systematic reviews of preclinical research data, and develop preclinical common data elements (CDEs) for epilepsy research in animals.

    There is growing appreciation that process improvement holds promise for improving quality and efficiency across the translational research continuum but frameworks for such programs are not often described. The purpose of this paper is to present a framework and case examples of a Research Process Improvement Program implemented at Tufts CTSI. To promote research process improvement, we developed online training seminars, workshops, and in-person consultation models to describe core process improvement principles and methods, demonstrate the use of improvement tools, and illustrate the application of these methods in case examples. We implemented these methods, as well as relational coordination theory, with junior researchers, pilot funding awardees, our CTRC, and CTSI resource and service providers. The program focuses on capacity building to address common process problems and quality gaps that threaten the efficient, timely and successful completion of clinical and translational studies. © 2015 The Authors.

    Traditionally, in ethical guidelines and in research ethics literature, care and research are clearly separated based on their different objectives. In contrast, in paediatric oncology, research and care are closely combined. Currently, it is unknown how relevant actors in paediatric oncology perceive this combination of research and care. We conducted a qualitative study into the experiences of those involved in Dutch paediatric oncology with the intertwinement of research and care and the dual role of paediatric oncologists as researchers and treating physicians. A qualitative study approach, using two focus groups and 19 semi-structured, in-depth interviews with paediatric oncologists, research coordinators, parents of children with cancer, and adolescents with cancer. Four themes characterize how actors experience the intertwinement of research and care in paediatric oncology. First, research is considered of major importance, and paediatric oncology professionals convey this message to patients and their parents. Second, there is ambiguity about categorization of studies into cancer therapy as either research or treatment. Third, role conflicts appear within the work of the paediatric oncologists. Finally, the various benefits of combining treatment with research are emphasized. Research is regarded as a fundamental and indispensable characteristic of paediatric oncology practice. Paediatric oncology professionals, parents, and patients have a very positive outlook on combining research and care, but they may not be sufficiently critical with respect to potential conflicts. Increased reflection on how to optimally combine research and care could serve as an important protection of the interests of children with cancer and their parents. © 2015 Wiley Periodicals, Inc.

    The Clinical and Translational Science Award (CTSA) Workgroup for Comparative Effectiveness Research (CER) Education, Training, and Workforce Development identified a need to delineate the competencies that practitioners and users of CER for patient-centered outcomes research, should acquire. With input from CTSA representatives and collaborators, we began by describing the workforce. We recognize the workforce that conducts CER and the end users who use CER to improve the health of individuals and communities. We generated a preliminary set of competencies and solicited feedback from the CER representatives at each member site of the CTSA consortium. We distinguished applied competencies (i.e., skills needed by individuals who conduct CER) from foundational competencies that are needed by the entire CER workforce, including end users of CER. Key competency categories of relevance to both practitioners and users of CER were: (1) asking relevant research questions; (2) recognizing or designing ideal CER studies; (3) executing or using CER studies; (4) using appropriate statistical analyses for CER; and (5) communicating and disseminating CER study results to improve health. Although CER is particularly broad concept, we anticipate that these preliminary, relatively generic competencies will be used in tailoring curricula to individual learners from a variety of programmatic perspectives. © 2012 Wiley Periodicals, Inc.

    Full text: The discovery of the quasi-crystals [D. Schechtman et. Al., Phys.] Rev. Lett. [53, 1951-1953 (1984)] made very narrow definition of the crystalline state based on the periodicity of a local arrangement of atoms. Since the definition of this State has been a matter of much controversy [G.R. Desiraju, Nature 423, 485 (2003); S. van Smaalen, IUCR Aperiodic Commission Reports. August 7, 2002; International Union of Crystallography. Report of the Executive Committee for 1991; ACTA Cryst. A48, 922-946 (1992)]. We will make a presentation of the current time of the crystallography in this regard from the conceptual point of view. We show the use of the formalism of algorithmic complexity or Kolmogorov [M. Li and P. Vitanyi, An Introduction to Kolmogorov Complexity and Its Applications (Springer Verlag, Heidelberg, 1993), W.H. Zurek, Phys.] Rev. 40, 4731 (1989); Nature 341, 119-124 (1989)] provides a different perspective on the nature of the Crystallographic order. Infinite crystals can be considered solid with zero algorithmic complexities by atom. Show statistical analysis of inorganic compounds [J.L.C. Daams et al., Atlas of Crystal Structure Types for Intermetallic Phases (ASM International, Ohio, 1991), Fachinformationszentrum/NIST Inorganic Crystal Structure Database, Karlsruhe (2003) icsd.fkf.mpg.de] demonstrating that the minimization of complexity is a trend in the crystalline arrangement. We will then compare the degree of disorder of some typical solids according to their algorithmic complexity. Finally, space diffraction will be studied from this same perspective and will be discussed that zero algorithmic complexities by point in space of diffraction does not necessarily imply the same thing for the Atomic arrangement. The discrete portion of the diffraction pattern is a fingerprint of the underlying order but not the actual existence of long-range order. Experimental results will be showcased [E.

    To explore barriers to midwives and nurses addressing mental health issues with women during the perinatal period. Perinatal mental health is considered an important public health issue with health policy internationally identifying the importance of psychological support for women in the perinatal period. Midwives and primary care nurses are ideally positioned to detect mental distress early, but evidence suggests that they are reluctant to discuss mental health issues with women during pregnancy or in the postnatal period. The research used a descriptive design. A total of 809 midwives and nurses completed an anonymous, online or hard copy survey. Designed by the research team, the survey listed 26 potential barriers to the provision of perinatal mental health care. Participants identified organisational factors as presenting the greatest barriers. Organisational barriers included lack of perinatal mental health services, absence of care pathways, heavy workload, lack of time, lack of privacy and not seeing women regularly enough to build a relationship. Over 50% of participants identified practitioner-related barriers, such as lack of knowledge on perinatal mental health and cultural issues; lack of skill, in particular, skills to respond to a disclosure of a mental health issue; and fears of causing women offence and distress. Findings also indicated that the context of care and education influenced the degree to which participants perceived certain items as barriers. Midwives and primary care nurses encounter many organisational- and practitioner-related barriers that negatively impact on their ability to incorporate mental health care into their practice. Midwifery and nursing services need to develop strategies to address system- and practitioner-related barriers, including the development of services and care pathways, and the provision of culturally sensitive education on perinatal mental health in order to support practitioners to address issues with

    Disruption of circadian function has been observed in several human disorders, including bipolar disorder (BD). Research into these disorders can be facilitated by human cellular models that evaluate external factors (zeitgebers) that impact circadian pacemaker activity. Incorporating a firefly luciferase reporter system into human fibroblasts provides a facile, bioluminescent readout that estimates circadian phase, while leaving the cells intact. We evaluated whether this system can be adapted to clinical BD research and whether it can incorporate zeitgeber challenge paradigms. Fibroblasts from patients with bipolar I disorder (BD-I) (n = 13) and controls (n = 12) were infected ex vivo with a lentiviral reporter incorporating the promoter sequences for Bmal1, a circadian gene to drive expression of the firefly luciferase gene. Following synchronization, the bioluminescence was used to estimate period length. Phase response curves (PRCs) were also generated following forskolin challenge and the phase response patterns were characterized. Period length and PRCs could be estimated reliably from the constructs. There were no significant case-control differences in period length, with a nonsignificant trend for differences in PRCs following the phase-setting experiments. An ex vivo cellular fibroblast-based model can be used to investigate circadian function in BD-I. It can be generated from specific individuals and this could usefully complement ongoing circadian clinical research. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Emphasis on translational research to facilitate progression from the laboratory into the community also creates a dynamic in which ethics and social policy questions and solutions are ever pressing. In response, academic institutions are creating Research Ethics Consultation Services (RECS). All Clinical Translational Science Award institutions were surveyed in early 2010 to determine which institutions have a RECS in operation and what is their composition and function. Of the 46 institutions surveyed, 33 (70%) have a RECS. Only 15 RECS have received any consult requests in the last year. Issues that are common among these relatively nascent services include relationships with institutional oversight committees, balancing requestor concerns about confidentiality with research integrity and human subjects protection priorities, tracking consult data and outcomes, and developing systems for internal evaluation. There is variability in how these issues are approached. It will be important to be attentive to the institutional context to develop an appropriate approach. Further data about the issues raised by requestors and the recommendations provided are necessary to build a community of scholars who can navigate and resolve ethical issues encountered along the translational research pathway. © 2012 Wiley Periodicals, Inc.

    This project aimed to develop an open-access website providing adaptable resources to facilitate best practices for multisite research from initiation to closeout. methods: A web-based assessment was sent to the leadership of the Clinical and Translational Science Award (CTSA) Community Engagement Key Functions Committee (n= 38) and the CTSA-affiliated Primary Care Practice-based Research Networks (PBRN, n= 55). Respondents rated the benefits and barriers of multisite research, the utility of available resources, and indicated their level of interest in unavailable resources. Then, existing research resources were evaluated for relevance to multisite research, adaptability to other projects, and source credibility. Fifty-five (59%) of invited participants completed the survey. Top perceived benefits of multisite research were the ability to conduct community-relevant research through academic-community partnerships (34%) and accelerating translation of research into practice (31%). Top perceived barriers were lack of research infrastructure to support PBRNs and community partners (31%) and inadequate funding to support multisite collaborations (26%). Over 200 resources were evaluated, of which 120 unique resources were included in the website. The PRIMER Research Toolkit (http://www.researchtoolkit.org) provides an array of peer-reviewed resources to facilitate translational research for the conduct of multisite studies within PBRNs and community-based organizations. © 2011 Wiley Periodicals, Inc.

    The researcher role is highly debated in qualitative research. This article concerns the researcher-researched relationship. A group of health science researchers anchored in various qualitative research traditions gathered in reflective group discussions over a period of two years. Efforts to establish an anti-authoritarian relationship between researcher and researched, negotiation of who actually "rules" the research agenda, and experiences of shifts in "inferior" and "superior" knowledge positions emerged as central and intertwined themes throughout the discussions. The dual role as both insider and outsider, characteristic of qualitative approaches, seemed to lead to power relations and researcher vulnerability which manifested in tangible ways. Shifting positions and vulnerability surfaced in various ways in the projects. They nonetheless indicated a number of similar experiences which can shed light on the researcher-researched relationship. These issues could benefit from further discussion in the qualitative health research literature.

    Despite the abundance of sociological research on the gender wage gap, questions remain. In particular, the role of cohorts is under investigated. Using data from the Current Population Survey, we use Age-Period-Cohort analysis to uniquely estimate age, period, and cohort effects on the gender wage gap. The narrowing of the gender wage gap that occurred between 1975 and 2009 is largely due to cohort effects. Since the mid-1990s, the gender wage gap has continued to close absent of period effe...

    The characteristic symptoms of restless legs syndrome (RLS) have been known for hundreds of years and were first reported in medicine in the 1600s. Clinicians must consider potential mimics, comorbid, and associated conditions when evaluating children with RLS symptoms. The traditional differentiation of RLS from periodic limb movement disorder (PLMD) is noted in children as well as adults. Because current pediatric RLS research is sparse, this article provides the most up-to-date evidence-based as well as consensus opinion-based information on the subject of childhood RLS and PLMD. Prevalence, pathophysiology, diagnosis, treatment, and clinical associations are discussed. Copyright © 2011 Elsevier Inc. All rights reserved.

    A full implementation of analytical energy gradients for molecular and periodic systems is reported in the TURBOMOLE program package within the framework of Kohn-Sham density functional theory using Gaussian-type orbitals as basis functions. Its key component is a combination of density fitting (DF) approximation and continuous fast multipole method (CFMM) that allows for an efficient calculation of the Coulomb energy gradient. For exchange-correlation part the hierarchical numerical integration scheme (Burow and Sierka, Journal of Chemical Theory and Computation 2011, 7, 3097) is extended to energy gradients. Computational efficiency and asymptotic O(N) scaling behavior of the implementation is demonstrated for various molecular and periodic model systems, with the largest unit cell of hematite containing 640 atoms and 19,072 basis functions. The overall computational effort of energy gradient is comparable to that of the Kohn-Sham matrix formation. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  7. Periodic Poisson Solver for Particle Tracking

    Dohlus, M.; Henning, C.

    2015-05-01

    A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a free space (or open) boundary is realized. In beam physics, this approach allows to calculate the space charge field of a continualized charged particle distribution with periodic pattern. The method is based on a particle mesh approach with equidistant grid and fast convolution with a Green's function. The periodic approach uses only one period of the source distribution, but a periodic extension of the Green's function. The approach is numerically efficient and allows the investigation of periodic- and pseudo-periodic structures with period lengths that are small compared to the source dimensions, for instance of laser modulated beams or of the evolution of micro bunch structures. Applications for laser modulated beams are given.

    Full Text Available Objective – To determine whether the availability of free digital versions of books impacts print sales.Design – Quantitative data comparison.Setting – University Instructional Psychology Department.Subjects – A total of 41 books, each with a free digital version and a traditional print version.Methods – This study used Nielson BookScan data to track print book sales during a 16-week period, 8 weeks before a free digital version of the book became available and 8 weeks after the availability of the free digital version. The authors tracked 41 books and organized them into four categories. The first included 7 nonfiction books, the second consisted of 5 science fiction/fantasy books, the third included 5 science fiction/fantasy books released together by Random House, and the fourth group consisted of 24 science fiction/fantasy books released by Tor Books. The books released by Tor Books, unlike the other books in the study, were available by free download only if a person registered for Tor’s newsletter and the downloads were only available for one week. When a free digital book from any of the other three groups was released, it remained available for several weeks, and more often, indefinitely.Main Results – Combined print sales of the nonfiction titles in the first group increased 5% after the release of a free digital copy. The majority of the science fiction/fantasy books in the second group also had an increase in post-free release sales, with a combined increase of 26%. The combined sales of the Random House titles increased by 9% after the release of the free digital versions. However, in stark contrast to the results of the first three groups, the fourth group of Tor books had a combined decrease in print sales of 18%. While the authors were not able to explain this difference with certainty, they point out that the Tor model for releasing the free digital books (making the free books available for only one week and

    2013-05-01

    Social networking sites (SNS) have potential value in the field of medical genetics as a means of research subject recruitment and source of data. This article examines the current role of SNS in medical genetics research and potential applications for these sites in future studies. Facebook is the primary SNS considered, given the prevalence of its use in the United States and role in a small but growing number of studies. To date, utilization of SNS in medical genetics research has been primarily limited to three studies that recruited subjects from populations of Facebook users [McGuire et al. (2009); Am J Bioeth 9: 3-10; Janvier et al. (2012); Pediatrics 130: 293-298; Leighton et al. (2012); Public Health Genomics 15: 11-21]. These studies and a number of other medical and public health studies that have used Facebook as a context for recruiting research subjects are discussed. Approaches for Facebook-based subject recruitment are identified, including paid Facebook advertising, snowball sampling, targeted searching and posting. The use of these methods in medical genetics research has the potential to facilitate cost-effective research on both large, heterogeneous populations and small, hard-to-access sub-populations.

    Conclusions: Although it is premature to conclude that periodized exercise is superior to non-periodized exercise for improving health outcomes, periodization appears to be a feasible means of prescribing exercise to inactive adults within an intervention setting. Further research is necessary to understand the effectiveness of periodizing aerobic exercise, the psychological effects of periodization, and the feasibility of implementing flexible non-linear methods.

  15. Laboratory rhesus macaque social housing and social changes: Implications for research.

    2017-01-01

    Macaque species, specifically rhesus (Macaca mulatta), are the most common nonhuman primates (NHPs) used in biomedical research due to their suitability as a model of high priority diseases (e.g., HIV, obesity, cognitive aging), cost effective breeding and housing compared to most other NHPs, and close evolutionary relationship to humans. With this close evolutionary relationship, however, is a shared adaptation for a socially stimulating environment, without which both their welfare and suitability as a research model are compromised. While outdoor social group housing provides the best approximation of a social environment that matches the macaque behavioral biology in the wild, this is not always possible at all facilities, where animals may be housed indoors in small groups, in pairs, or alone. Further, animals may experience many housing changes in their lifetime depending on project needs, changes in social status, management needs, or health concerns. Here, we review the evidence for the physiological and health effects of social housing changes and the potential impacts on research outcomes for studies using macaques, particularly rhesus. We situate our review in the context of increasing regulatory pressure for research facilities to both house NHPs socially and mitigate trauma from social aggression. To meet these regulatory requirements and further refine the macaque model for research, significant advances must be made in our understanding and management of rhesus macaque social housing, particularly pair-housing since it is the most common social housing configuration for macaques while on research projects. Because most NHPs are adapted for sociality, a social context is likely important for improving repeatability, reproducibility, and external validity of primate biomedical research. Am. J.

They were assessed on Beck Depression Inventory thrice viz. during third trimester of pregnancy, within 3 days of delivery (early postpartum period) & within 4-8 weeks of delivery (late postpartum period).The prevalence of depression was 8.3%, 20% and 12.8% respectively at three ratings. The incidence was 16% and 10% in the early & late postpartum period respectively. Further analysis revealed that depression in pregnancy correlated significantly with depression in early postpartum period, but not with late postpartum period. Depression in early postpartum period correlated with depression in late postpartum period.These findings have implications for early detection and care of women at risk for developing depression.

  2. Period Estimation in Astronomical Time Series

    2011-09-01

    Detection of periodicity and period estimation in non-uniformly sampled time series data is frequently a goal in Astronomical data analysis. There are various problems faced: Firstly, data is sampled non-uniformly which makes it difficult to use simple Fourier transform for performing spectral analysis. Secondly, there are large gaps in data which makes it difficult to interpolate the signal for re-sampling. Finally, in data sets with smaller time periods the non-uniformity in sampling and noise in data pose even greater problems because of the lesser number of samples per period. In this talk we review existing methods and then we propose new approaches in determining periods. We first use correntropy (an alternative to autocorrelation) that encapsulates non-linear correlations using a spatio-temporal kernel to estimate accurately the time period of the data. The other uses periodic kernels in non-parametric Gaussian process. These new techniques are also used for identifying periodic signals.

    It is unknown how often cardiac arrhythmias occur in hypokalemic periodic paralysis (HypoPP) and if they are caused by hypokalemia alone or other factors. This systematic review shows that cardiac arrhythmias were reported in 27 HypoPP patients. Cases were confirmed genetically (13 with an R528H mutation in CACNA1S, 1 an R669H mutation in SCN4A) or had a convincing clinical diagnosis of HypoPP (13 genetically undetermined) if reported prior to the availability of genetic testing. Arrhythmias occurred during severe hypokalemia (11 patients), between attacks at normokalemia (4 patients), were treatment-dependent (2 patients), or unspecified (10 patients). Nine patients died from arrhythmia. Convincing evidence for a pro-arrhythmogenic factor other than hypokalemia is still lacking. The role of cardiac expression of defective skeletal muscle channels in the heart of HypoPP patients remains unclear. Clinicians should be aware of and prevent treatment-induced cardiac arrhythmia in HypoPP. Copyright © 2014 Wiley Periodicals, Inc.

    Many nursing studies are conducted in the United States, Europe, and Australia, where only a fourth of the world's population resides. There is a need to promote nursing research in Asia to enhance the contextual relevance of their evidence-based nursing interventions. A first step toward this goal is to determine the perceived research capacity among nursing faculty in academic settings in the Philippines. This study described the perceived research capacity among nursing faculty of the University of Santo Tomas - College of Nursing, Manila, Philippines. The study used a survey that contained four sections: subject demographics; knowledge and skill on research designs and research process; research involvement, services, and incentives; and factors affecting research involvement. Chi-square test of homogeneity and MANOVA analyzed the gathered data. Findings showed that the faculty perceived themselves as knowledgeable and skillful in conducting research. However, current teaching assignments hindered their capacity to conduct research. University-sponsored incentives and college-based research services had also remained underutilized despite their availability. Overall, heavy teaching load was the greatest hindrance to research endeavors. Actions must be taken to reconfigure effort allocations with careful consideration of existing university and institutional bylaws. © 2016 Wiley Periodicals, Inc.

  12. Extracting Fundamental Periods to Segment Biomedical Signals.

    We address the problem of segmenting nearly periodic time series into period-like segments. We introduce a definition of nearly periodic time series via triplets 〈 basic shape, shape transformation, time scaling 〉 that covers a wide range of time series. To split the time series into periods, we select a pair of principal components of the Hankel matrix. We then cut the trajectory of the selected principal components by its symmetry axis and, thus, obtaining half-periods that are merged into segments. We describe a method of automatic selection of periodic pairs of principal components, corresponding to the fundamental periodicity. We demonstrate the application of the proposed method to the problem of period extraction for accelerometric time series of human gait. We see the automatic segmentation into periods as a problem of major importance for human activity recognition problem, since it allows to obtain interpretable segments: each extracted period can be seen as an ultimate entity of gait. The method we propose is more general compared to the application specific methods and can be used for any nearly periodical time series. We compare its performance to classical mathematical methods of period extraction and find that it is not only comparable to the alternatives, but in some cases performs better.

    The involvement of consumers and the general public in improving cancer services is an important component of health services. However, consumer involvement in cancer research is relatively unexplored. The objective of this study was to explore different ways of involving consumers in cancer research in one regional network. Thames Valley Cancer Network Consumer Research Partnership (CRP) group was formed in 2009. The group consists of consumers and professionals to help in promoting consumer involvement in Cancer Research in the Thames Valley. This study evaluated the project of consumer involvement in cancer research in the Thames Valley from March 2010 to March 2011. We used different indices to judge the level of consumer involvement: number of projects involving consumers through the group, types of projects, level of involvement (ranged from consultation on research documents to collaborating in preparing grant applications) and the methods of involving consumers in cancer research. Fifteen projects were submitted to the CRP group during the 12-month period studied. Of these, eight projects were clinical trials, three were qualitative research projects, two were patients' surveys and two were non-randomized interventional studies. Seven projects requested consumer involvement on patient information sheets for clinical trials. Of these seven applications, three also requested consumers' help in designing research questionnaires and another three requested that consumers should be involved in their project management group. In addition, four projects involved consumers in the proposal development phase and another four projects asked for advice on how to increase trial recruitment, conduct patient interviews or help with grant applications. The creation of the CRP and this audit of its activity have documented consumer involvement in cancer research in the Thames Valley. We have clearly shown that consumers can be involved in designing and managing cancer
