    In November of 2009, Clemson University was awarded a competitive grant from the U.S. Department of Energy to design, build and operate a facility for full-scale, highly accelerated mechanical testing of next-generation wind turbine drivetrain technologies. The primary goal of the project was to design, construct, commission, and operate a state-of-the-art sustainable facility that permits full-scale highly accelerated testing of advanced drivetrain systems for large wind turbines. The secondary goal was to meet the objectives of the American Recovery and Reinvestment Act of 2009, especially in job creation, and provide a positive impact on economically distressed areas in the United States, and preservation and economic recovery in an expeditious manner. The project was executed according to a managed cooperative agreement with the Department of Energy and was an extraordinary success. The resultant new facility is located in North Charleston, SC, providing easy transportation access by rail, road or ship and operates on an open access model such that it is available to the U.S. Wind Industry for research, analysis, and evaluation activities. The 72 m by 97 m facility features two mechanical dynamometer test bays for evaluating the torque and blade dynamic forces experienced by the rotors of wind turbine drivetrains. The dynamometers are rated at 7.5 MW and 15 MW of low speed shaft power and are configured as independent test areas capable of simultaneous operation. All six degrees of freedom, three linear and three rotational, for blade and rotor dynamics are replicated through the combination of a drive motor, speed reduction gearbox and a controllable hydraulic load application unit (LAU). This new LAU setup readily supports accelerated lifetime mechanical testing and load analysis for the entire drivetrain system of the nacelle and easily simulates a wide variety of realistic operating scenarios in a controlled laboratory environment.

    O'Sell, Elizabeth Eberhart

    The Clemson University Science Master's Program (SMP) in Sustainable and Resilient Infrastructure is a program which aims to link engineering, materials, construction, environment, architecture, business, and public policy to produce graduates with unique holistic perspective and expertise to immediately contribute to the workforce in the area of sustainable and resilient infrastructure. A program evaluation of the SMP has been performed to study the effectiveness of the SMP and identify areas where the goals and vision of the SMP are achieved and areas where improvements can be made. This was completed by analysis of trends within survey responses, review of Master's thesis reports, and review of courses taken. It was found that the SMP has facilitated new interdisciplinary research collaborations of faculty in different concentration areas within the Glenn Department of Civil Engineering, as well as collaboration with faculty in other departments. It is recommended that a course which provides instruction in all eight competency areas be required for all SMP students to provide a comprehensive overview and ensure all students are exposed to concepts of all competency areas. While all stakeholders are satisfied with the program and believe it has been successful thus far, efforts do need to be made as the program moves forward to address and improve some items that have been mentioned as needing improvement. The concerns about concentration courses, internship planning, and advising should be addressed. This evaluation provides benefits to prospective students, current SMP participants, and outside program supporters. The goal of this evaluation is to provide support that the SMP is an effective and worthwhile program for participating students, while attempting to identify any necessary program improvements and provide recommendations for achieving these improvements. This goal has been accomplished.

    Advanced materials and the science and engineering related to their design, process, test and manufacture represents one of the fast growing sectors of the Materials Science and Engineering field. Awareness of existing process, performance, manufacturing or recycle-ability issues and limitations, often dictates the next generation of advances needed to improve existing or create new materials. To compete in this growing science and technology area, trained experts must possess strong academic skills in their discipline as well as advanced communication, networking and cultural teamwork experience. Clemson's School of Materials Science and Engineering (MSE), is continuing to expand our program to focus on unique capabilities which support local, regional and national needs in advanced materials. Specifically, MSE at Clemson is evolving to highlight intrinsic strengths in research and education areas related to optical materials, advanced fibers and composites (based on inorganic, organic and natural fibers), biomaterials and devices, and architectural and restoration material science (including the conservation and preservation of maritime structures). Additionally, we continue to invest in our expertise in materials design and fabrication, which has historically supported our well known programs in ceramics and textiles. In addition to a brief review of the School's forward-looking challenges to remain competitive among strong southeast regional materials science programs, this presentation will also highlight recent technical advances in fiber-based materials for nanofluidic applications. Specifically we will present recent results on design of fiber-based nanofluidics for sensor applications and we will discuss some physical phenomena associated with liquid transport at nanoscale.

    2010-09-17

    Since the early 1990s, Los Alamos National Laboratory (LANL) has applied electric grid models and simulation software to problems of national significance. This effort continues with a variety of other projects funded by the Department of Energy (DOE), other federal and state agencies and private companies. Critical to the success of these programs is the ability to integrate regional-scale models of the electric grid, to assess the propagation of grid impacts, and to present interactively the effect of potential mitigating actions required to stabilize the grid. All of these capabilities are applied in this study, to accomplish the following goals and objectives: (1) Develop an AC power flow model representing future conditions within New Mexico's electric grid, using commercial tools accepted by the utility industry; (2) Conduct a 'screening' analysis of options for accelerating potential renewable energy development through the addition of a statewide transmission collector system; (3) Estimate total revenue needed, jobs created (temporary and permanent) plus indirect and direct impacts to the state's economy; (4) Evaluate potential cost allocation methodology; and (5) Issue a project report that will provide information for policy direction by state regulators, project developers, and legislators.

    Serdinak, Thomas E.

    1994-01-01

    An experimental investigation of the post-impact fatigue response of integrally woven carbon/epoxy composites was conducted. Five different through-the-thickness (TTT) reinforcing fibers were used in an experimental textile process that produced an integrally woven (0/90/0/90/0/90/0/90/0)(sub T) ply layup with 21K AS4 carbon tow fiber. The resin was Hercules 3501-6, and the five TTT reinforcing fibers were Kevlar, Toray carbon, AS4 carbon, glass, and IM6 carbon. The purpose of this investigation was to study the post-impact fatigue response of these material systems and to identify the optimum TTT fiber. Samples were impacted with one half inch diameter aluminum balls with an average velocity of 543 ft/sec. Post-impact static compression and constant amplitude tension-compression fatigue tests were conducted. Fatigue tests were conducted with a loading ratio of R=-5, and frequency of 4 Hz. Damage growth was monitored using x-radiographic and sectioning techniques and by examining the stress-strain response (across the impact site) throughout the fatigue tests. The static compressive stress versus far-field strain response was nearly linear for all material groups. All the samples had a transverse shear failure mode. The average compressive modulus (from far-field strain) was about 10 Msi. The average post-impact static compressive strength was about 35.5 Ksi. The IM6 carbon sample had a strength of over 40 Ksi, more than 16 percent stronger than average. There was considerable scatter in the S-N data. However, the IM6 carbon samples clearly had the best fatigue response. The response of the other materials, while worse than IM6 carbon, could not be ranked definitively. The initial damage zones caused by the impact loading and damage growth from fatigue loading were similar for all five TTT reinforcing materials. The initial damage zones were circular and consisted of delaminations, matrix cracks and ply cracks. Post-impact fatigue loading caused delamination growth

    The NASA study activities in preparation for a Space Station began in the early 1970's. The early studies included many in-house NASA and contracted studies. A group of representatives from all the NASA Centers, titled the Space Station Concept Development Group (CDG) was involved in the studies which led to the initiation of the Space Station Program. The CDG studies were performed over a period of approximately one year and consisted of four phases. The initial phase had the objective to determine the functions required of the station as opposed to a configuration. The activities of the second phase were primarily concerned with a sizing of the facilities required for payloads and the resources necessary to support these mission payloads. The third phase of studies was designed to develop a philosophical approach to a number of areas related to autonomy, maintainability, operations and logistics, and verification. The fourth phase of the study was to be concerned with configuration assessment activities.

    2012-06-01

    We report on the development of a multifunctional magnetic rotator that has been built and used during the last five years by two groups from Clemson and Drexel Universities studying the rheological properties of microdroplets. This magnetic rotator allows one to generate rotating magnetic fields in a broad frequency band, from hertz to tens kilohertz. We illustrate its flexibility and robustness by conducting the rheological studies of simple and polymeric fluids at the nano and microscale. First we reproduce a temperature-dependent viscosity of a synthetic oil used as a viscosity standard. Magnetic rotational spectroscopy with suspended nickel nanorods was used in these studies. As a second example, we converted the magnetic rotator into a pump with precise controlled flow modulation. Using multiwalled carbon nanotubes, we were able to estimate the shear modulus of sickle hemoglobin polymer. We believe that this multifunctional magnetic system will be useful not only for micro and nanorheological studies, but it will find much broader applications requiring remote controlled manipulation of micro and nanoobjects.

  9. TELEVISION AND DEVELOPMENT OF RURAL WOMENA STUDY

    Directory of Open Access Journals (Sweden)

    Dr. Devadas M.B,

    2015-10-01

    Full Text Available Television as a mass medium has profound impact on society. The pivotal role of Television as an instrument of development by altering the human perspective and transforming the traditional mindset of society is well recognized. TV has not only occupied the leisure hours of women but the whole family is also found busy viewing television programmes for varying length of hours. This paper basically intends to examine the role of TV in the development of rural women. The term development in its broadest sense in the context of India refers to rural development. Rural development has been viewed as an economic planned change to achieve desirable social goals in India since independence. Eapen (1988: 67, in his diagnosis and analysis opens up the Pandora of problems related to the inherent conflicts and contradiction between the state policy regarding electronic media and actual use for development. This study quantitatively analyses the role of television in igniting development among rural women. Thiruvarur, one of the most back ward district in Tamil Nadu is taken as the locale of the study. Hundred rural women samples are selected for the research. This research paper underscores that TV has profound impact on social, economic, cultural and political life of rural women

  10. Active controlled studies in antibiotic drug development.

    Science.gov (United States)

    Dane, Aaron

    2011-01-01

    The increasing concern of antibacterial resistance has been well documented, as has the relative lack of antibiotic development. This paradox is in part due to challenges with clinical development of antibiotics. Because of their rapid progression, untreated bacterial infections are associated with significant morbidity and mortality. As a consequence, placebo-controlled studies of new agents are unethical. Rather, pivotal development studies are mostly conducted using non-inferiority designs versus an active comparator. Further, infections because of comparator-resistant isolates must usually be excluded from the trial programme. Unfortunately, the placebo-controlled data classically used in support of non-inferiority designs are largely unavailable for antibiotics. The only available data are from the 1930s and 1940s and their use is associated with significant concerns regarding constancy and assay sensitivity. Extended public debate on this challenge has led to proposed solutions by some in which these concerns are addressed by using very conservative approaches to trial design, endpoints and non-inferiority margins, in some cases leading to potentially impractical studies. To compound this challenge, different Regulatory Authorities seem to be taking different approaches to these key issues. If harmonisation does not occur, antibiotic development will become increasingly challenging, with the risk of further decreases in the amount of antibiotic drug development. However with clarity on Regulatory requirements and an ability to feasibly conduct global development programmes, it should be possible to bring much needed additional antibiotics to patients.

    Full Text Available Spatial visualization, frequently used in many stages of daily life, is also an indispensable part of mathematics and geometry courses. There are many definitions of spatial visualization ability and various tests have been developed to measure this ability. The aim of this study is to develop a new test for determining the spatial visualization ability for students in higher education. For this purpose, a test including 29 items was prepared. The developed test’s pilot scheme was applied to 236 students of mathematics and mathematics education programs in different two state universities. The data obtained were analyzed by packaged software like Iteman 4, SPSS 17.0 and Lisrel8.7. The test, which was developed by discarding two items according to results of item analysis, validity and reliability analysis and confirmatory factor analysis, was finalized. The Cronbach α coefficient of test was calculated as .84 and RMSEA value of test was calculated as 0,032.

    This contract provides the research support for a group concerned with a relatively large range of problems. The integrating thread that runs through it is that of an interest in development and its genetic regulation, mainly in complex organisms and with an emphasis on the immune system as a model for developmental analysis and as a tool for following the development of other systems, especially the brain. It includes studies of biochemical genetics, primarily from a developmental viewpoint and with particular regard to defense mechanisms, and cellular aspects of the immune system. It extends into the area of cancer immunology and cell specificities as related to tumor systems, primarily from an immunogenetic viewpoint and with particular reference to leukemias in the mouse, and to disruptions of genetic control mechanisms in tumor development, especially as approached through the reappearance of fetal antigens associated with tumor development.

    2005-03-01

    The comparative study of infant development and animal cognition brings to cognitive science the promise of insights into the nature and origins of cognitive skills. In this article, I review a recent wave of comparative studies conducted with similar methodologies and similar theoretical frameworks on how two core components of human cognition--object permanence and gaze following--develop in different species. These comparative findings call for an integration of current competing accounts of developmental change. They further suggest that evolution has produced developmental devices capable at the same time of preserving core adaptive components, and opening themselves up to further adaptive change, not only in interaction with the external environment, but also in interaction with other co-developing cognitive systems.

    The Advanced Fuel Cycle Initiative (AFCI) Safeguards Campaign aims to develop safeguards technologies and processes that will significantly reduce the risk of proliferation in the U.S. nuclear fuel cycle of tomorrow. The Safeguards Enhancement Study was chartered with identifying promising research and development (R&D) directions over timescales both near-term and long-term, and under safeguards oversight both domestic and international. This technology development roadmap documents recognized gaps and needs in the safeguarding of nuclear fuel cycles, and outlines corresponding performance targets for each of those needs. Drawing on the collective expertise of technologists and user-representatives, a list of over 30 technologies that have the potential to meet those needs was developed, along with brief summaries of each candidate technology. Each summary describes the potential impact of that technology, key research questions to be addressed, and prospective development milestones that could lead to a definitive viability or performance assessment. Important programmatic linkages between U.S. agencies and offices are also described, reflecting the emergence of several safeguards R&D programs in the U.S. and the reinvigoration of nuclear fuel cycles across the globe.

    Exophiala pisciphila is a dematiaceous fungus that belongs to a group of fungi known as the 'black yeasts'. It was isolated from the skin lesions of a smooth dogfish, Mustelus canis Mitchill, that had been born in the shark exhibit tank of the New York Aquarium. The different stages of development of this fungus were studied by light microscopy and scanning electron microscopy to illustrate the morphology and surface structures of conidia and mycelium. The list of marine and fresh water fish, which have been infected by Exophiala spp. and Exophiala-like fungi has been up-dated. Potato Dextrose Agar and Malt Agar proved to be the best growth media, while Corn Meal Agar proved to be the best medium for studying the morphological features of the conidia and mycelial development of E. pisciphila, which exhibited polymorphic conidiogenesis.

    A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

To this end, 72 students who registered in a six month study abroad program and 60 native speakers from U.S. Britain, Australia, and Canada agreed to participate in the present study. The learners in this investigation were tested at three phases. In the first phase, the study abroad (SA group was given a Discourse Completion Task (DCT at the beginning of the program as a pre-test. Three months later the same test was administered to the learners as post-test 1 and subsequently at the end of the program once again the test was given to the learners as post-test 2 in order to measure their achievement after three and six months sojourn. The native speakers were also asked to fill the DCT in order to compare the learners’ responses to the native speakers’. Finally, through comparing the learners’ performances in pre-test and post-tests with each other and with the native speakers’, it was found out that first, majority of learners and native speakers used conventionally indirect strategies in their request utterances, second, the number of strategies used by the students steadily increased over time from pre-test to the first and second post-test and third, the type of request strategies used by learners changed to be native like at the end of their sojourn.Keywords: interlanguage pragmatics, pragmatic competence, request strategies, speech acts, study abroad

    PET is uniquely capable of providing information on biochemical transformations in the living human body. Although most of the studies of monoamine oxidase (MAO) have focused on measurements in the brain, the role of peripheral MAO as a phase 1 enzyme for the metabolism of drugs and xenobiotics is gaining attention (Strolin Benedetti and Tipton, 1998; Castagnoli et al., 1997.). MAO is well suited for this role because its concentration in organs such as kidneys, liver and digestive organs is high sometimes exceeding that in the brain. Knowledge of the distribution of the MAO subtypes within different organs and different cells is important in determining which substrates (and which drugs and xenobiotics) have access to which MAO subtypes. The highly variable subtype distribution with different species makes human studies even more important. In addition, the deleterious side effects of combining MAO inhibitors with other drugs and with foodstuffs makes it important to know the MAO inhibitory potency of different drugs both in the brain and in peripheral organs (Ulus et al., 2000). Clearly PET can play a role in answering these questions, in drug research and development and in discovering some of the factors which contribute to the highly variable MAO levels in different individuals.

    Communications and development in the broadest sense of the terms are examined in relation to evaluation of the work of the Communication Foundation for Asia (CFA). CFA produces, in conjunction with public and private development agencies, flip-charts, comics, a fieldworker's handbook for use in family planning education, sound cassette magazines for agricultural extension work, booklets and sound-slides on forming cooperatives, and other educational materials. CFA operates in the Philippines. A developmental radio drama produced by CFA delivered a pro-development message, one that tells people they can do something about their conditions/situations, compared to the passive, consumer-oriented commercial radio drama. The most prominent theme was achievement. The characters had complex motivations and displayed wide range of motives. Like other forms of propaganda, developmental radio drama is not welcomed by radio station owners. Not many people in the industry perceive the opportunity for increasing overall development and economic growth. All pressures from commercial radio are in consumerist directions while developmental drama encourages production.

  7. Developing Fluorescent Hyaluronan Analogs for Hyaluronan Studies

    2012-02-01

    Full Text Available Two kinds of fluorescent hyaluronan (HA analogs, one serving as normal imaging agent and the other used as a biosensitive contrast agent, were developed for the investigation of HA uptake and degradation. Our approach of developing HA imaging agents depends on labeling HA with varying molar percentages of a near-infrared (NIR dye. At low labeling ratios, the hyaluronan uptake can be directly imaged while at high labeling ratios, the fluorescent signal is quenched and signal generation occurs only after degradation. It is found that the conjugate containing 1%–2% NIR dye can be used as a normal optical imaging agent, while bioactivable imaging agents are formed at 6% to 17% dye loading. It was determined that the conjugation of dye to HA with different loading percentages does not impact HA biodegradation by hyaluronidase (Hyal. The feasibility of using these two NIR fluorescent hyaluronan analogs for HA investigation was evaluated in vivo with optical imaging. The data demonstrates that the 1% dye loaded fluorescent HA can be used to monitor the behavior of HA and its fragments, whereas bioactivatable HA imaging agent (17% dye in HA is more suitable for detecting HA fragments.

    2015-01-01

    Because of the importance of x-ray interactions in modern medicine, efforts must be made to combine the fields of biology and physics. This paper reviews the development of an x-ray irradiation port that allows us to study the interaction of x-rays generated by highly charged ions with biological material, such as stem and cancer cells. Our goal is to better understand these interactions in order to improve the techniques of x-ray therapy by narrowing and specifically selecting the range of radiation energies applied. Using the Clemson University Electron Beam Ion Trap (CUEBIT), the generation of quasi-monochromatic x- rays from highly charged ions is possible. In order to maintain the integrity of the cells being studied, the cell culture needs to be oriented horizontally during the irradiation process. This poses a problem, as the highly charged ion beam generated at the CUEBIT is also oriented horizontally. Therefore, we have designed a system that employs a quadrupole bender that directs the ion beam vertically, which allows for the production of x-rays directly under the cell culture. The experimental station consists of a vacuum chamber that attaches to the end of the beam line. This chamber houses the quadrupole bender, a beryllium window for generating x-rays, and the interface between the beryllium window and the cell culture. X-rays must transmit through the bottom of a flask before they interact with the cells. Hence, we implement a procedure to replace the bottom of the flask with a thin layer of Mylar, allowing x-rays to penetrate through easily. We will use this system to study the effects of monochromatic x- rays on stem cells, cancer cells, and their associated proteins.

    Cruikshank, D. P.

    1983-01-01

    An historical account is given of the major figures, observational techniques and theories involved in Venus studies prior to space probe-based researches. Those who followed Galileo Galilei (1610) with the simple telescopes of the 17th and early 18th centuries confirmed the phases of the illuminated face of Venus. Lomonosov (1761) noted a gray halo surrounding the planet as it was partially silhouetted against the sun, and correctly inferred that Venus has an atmosphere. The brightness and nearly featureless appearance of the planet, together with the halo effect, led to the early conclusion that the atmosphere is cloudy. While visual and photographic spectroscopy had been applied to Venus many times, the first indication of spectral features different from the solar spectrum was found in 1932 with the high dispersion spectrograph on the Mt. Wilson 2.5-m telescope.

  17. BENCH SCALE SALTSTONE PROCESS DEVELOPMENT MIXING STUDY

    2011-08-03

    The Savannah River National Laboratory (SRNL) was requested to develop a bench scale test facility, using a mixer, transfer pump, and transfer line to determine the impact of conveying the grout through the transfer lines to the vault on grout properties. Bench scale testing focused on the effect the transfer line has on the rheological property of the grout as it was processed through the transfer line. Rheological and other physical properties of grout samples were obtained prior to and after pumping through a transfer line. The Bench Scale Mixing Rig (BSMR) consisted of two mixing tanks, grout feed tank, transfer pump and transfer hose. The mixing tanks were used to batch the grout which was then transferred into the grout feed tank. The contents of the feed tank were then pumped through the transfer line (hose) using a progressive cavity pump. The grout flow rate and pump discharge pressure were monitored. Four sampling stations were located along the length of the transfer line at the 5, 105 and 205 feet past the transfer pump and at 305 feet, the discharge of the hose. Scaling between the full scale piping at Saltstone to bench scale testing at SRNL was performed by maintaining the same shear rate and total shear at the wall of the transfer line. The results of scaling down resulted in a shorter transfer line, a lower average velocity, the same transfer time and similar pressure drops. The condition of flow in the bench scale transfer line is laminar. The flow in the full scale pipe is in the transition region, but is more laminar than turbulent. The resulting plug in laminar flow in the bench scale results in a region of no-mixing.

The bench scale tests should be considered to be conservative due to the highly laminar condition of flow that exists. Two BSMR runs were performed. In both cases, wall

  1. Software development practices in academia: a case study comparison

    CERN Document Server

    Groen, Derek; Grogan, James A; Schiller, Ulf D; Osborne, James M

    2015-01-01

    Academic software development practices often differ from those of commercial development settings, yet only limited research has been conducted on assessing software development practises in academia. Here we present a case study of software development practices in four open-source scientific codes over a period of nine years, characterizing the evolution of their respective development teams, their scientific productivity, and the adoption (or discontinuation) of specific software engineering practises as the team size changes. We show that the transient nature of the development team results in the adoption of different development strategies. We relate measures of publication output to accumulated numbers of developers and find that for the projects considered the time-scale for returns on expended development effort is approximately three years. We discuss the implications of our findings for evaluating the performance of research software development, and in general any computationally oriented scienti...

    Full Text Available Background: one of the deficiencies presented by physicians in their professional activity is related to the development of drug utilization studies. Objective: to design a professional development program aimed at physicians to develop drug utilization studies. Methods: an educational research was conducted at the Faculty of Medical Sciences of Cienfuegos during the 2011-2012 academic year. Theoretical methods such as the analytic-synthetic, the inductive-deductive, the historical-logical, modeling and system approach were used in the methodological and theoretical process. Results: the program aims at training physicians to develop drug utilization studies and its contents include: drug-related problems; criteria for selecting a drug in the prescription process; Pharmacoepidemiology; objectives, types of studies, characteristics and steps for the design and development of drug utilization studies; drug therapy and aspects on the selection and analysis of drug information sources. The methods are based on reflection and research itself developed by physicians during the activities for their professional development. Discussion and presentation of essays and research projects will be used to assess learning in the program, which integrates forms of professional development including specialized conferences, self-study, postgraduate courses, workshops and consultancies. Conclusions: the program serves as a reference to design the different activities required to train physicians for the development of drug utilization studies and it can be integrated in the graduate strategy of the university.

    The National Energy Strategy (NES) calls for a balanced program of greater energy efficiency, use of alternative fuels, and the environmentally responsible development of all U.S. energy resources. Consistent with the NES, a Department of Energy (DOE) program has been created to develop Advanced Turbine Systems (ATS). The technical ATS requirements are based upon two workshops held in Greenville, SC that were sponsored by DOE and hosted by Clemson University. The objective of this 8-year program, managed jointly by DOE`s Office of Fossil Energy, and, Office of Conservation and Renewable Energy, is to develop natural-gas-fired base load power plants that will have cycle efficiencies greater than 60%, lower heating value (LHV), be environmentally superior to current technology, and also be cost competitive. The program will include work to transfer advanced technology to the coal- and biomass-fueled systems being developed in other DOE programs.

    2012-06-01

    Full Text Available Karl Popper rightly says that “real starting point for each research is set based on assumptions of reality, not only based on the real facts”. The text below was prepared In accordance with this logic, where the Theories of International Development are treated especially focusing on International Economic Development. Therefore, theoretical reflections present assumption side, and study of many empirically measured data will correspond with real facts, because with ought these facts assumption would be useless. Technically this writing consists of two parts: in the first part are elaborated all theoretical and practical characteristics of overall international development, while in a second part as a case study will be Economic Development i Kosovo. From methodological point of view this is a comparative study and based on statistical data, while problem treating approach is critical and explanatory. As it will be understood later, development theories have been decisively influenced by economic thinking, and the focus on this dimension responds best to the nature of the term development. On the other hand the fact of unfolding economical development will reflect interference and the nature of it’s inter politics. Today economic development becomes a worldwide goal, having a considerable place in most of the literature with economic content. Also, here are presented as well examples from different practices that reflect economic development in different periods and places. Here is presented international economic development starting with a brief description of a genealogy of this development and ways of economic development back that time. It is of a special importance elaboration through theoretical approach on the creation of capital and economic development, as  mercantilist theory, classic and neo classic theory, than capitalization and Socialism-Marxism. To better understand the nature of economic development, the focus falls on

    2004-01-01

    The vulnerable eco-area is one of the important research targets in the field of sustainable development. It is the requirement of building a welloff society in an all-round way that we should study more on the vulnerable eco-areas, deal with the relationship between environmental protection and economic development, speed up the economic development in these areas and increase the living standard of the local people. This paper puts forward the countermeasures of environment-economy coordination, on the basis of the recognition of ecoenvironment features and social economic conditions in the vulnerable eco-areas of China, in view of the progress in sustainable development studies of the vulnerable ones, taking the transitional areas of farming and pasturing in northeast China as an example to study the regional environment vulnerability.

    2010-02-01

    The objective of the study was to examine whether infant neuromotor development is determined by fetal size and body symmetry in the general population. This study was embedded within the Generation R Study, a population-based cohort in Rotterdam. In 2965 fetuses, growth parameters were measured in mid-pregnancy and late pregnancy. After birth, at age 9 to 15 wks, neuromotor development was assessed with an adapted version of Touwen's Neurodevelopmental Examination. Less optimal neuromotor development was defined as a score in the highest tertile. We found that higher fetal weight was beneficial to infant neurodevelopment. A fetus with a 1-SD score higher weight in mid-pregnancy had an 11% lower risk of less optimal neuromotor development (OR: 0.89; 95% CI: 0.82-0.97). Similarly, a fetus with a 1-SD score larger abdominal-to-head circumference (AC/HC) ratio had a 13% lower risk of less optimal neuromotor development (OR: 0.87; 95% CI: 0.79-0.96). These associations were also present in late pregnancy. Our findings show that fetal size and body symmetry in pregnancy are associated with infant neuromotor development. These results suggest that differences in infant neuromotor development, a marker of behavioral and cognitive problems, are at least partly caused by processes occurring early in fetal life.

    Núñez, F Loreto; Sanz, B Javier; Mejía, L Gloria

    2015-01-01

    To investigate the association between dental caries and early childhood development in 3-year-olds from Talca, Chile. A pilot study with a convenience sample of 3-year-olds from Talca (n = 39) who attend public healthcare centers. Child development was measured by the Psychomotor Development Index (PDI), a screening tool used nationally among pre-school children to assess language development, fine motor skills and coordination areas. Dental caries prevalence was evaluated by decayed, missing, filled teeth (DFMT) and decayed, missing, filled tooth surfaces (DFMS) ceo-d and ceo-s indexes. The children were divided into two groups according to the PDIscore: those with a score of 40 or more were considered developmentally normal (n = 32), and those with a score below 40 were considered as having impaired development (n = 7). The severity of caries (DMFT) was negatively correlated with PDI (r = -0.82), and children with the lowest TEPSI score had the highest DFMT values. The average DMFT in children with normal development was 1.31, and 3.57 for those with impaired development. This pilot study indicates that the severity of dental caries is correlated with early childhood development. Copyright © 2015. Publicado por Elsevier España, S.L.U.

    Antonio Thiago Benedete da Silva

    2009-10-01

    Full Text Available Strategies for running companies in low-income markets have been in the spotlight in both the academic and the corporate environments.However, the first discussions about the relevance of such markets arose during the 1980s, when scenario-prospecting studies showed that popular markets would provide many opportunities around the year 2000.Indeed, at present, the base of the pyramid has many unaddressed needs that offer business possibilities for those companies that are willing to review their strategies. In this context, product development becomes increasingly important, since products targeting consumers of the C, D and E classes may need different features from those of goods manufactured for the A and B classes.The aim of this study is to revisit past popular market forecasts and to identify development trends for goods that target low- income consumers.Our results indicate that Wright and Johnson’s (1984 studies predicted that Brazil would maintain both qualitative and quantitative progress in its socioeconomic development over the next two decades and that the development of popular products is undergoing a buoyant phase.Several functional perspectives were used to develop an understanding of the phenomenon, especially marketing, engineering and manufacturing.Key words: Future studies. Popular markets. Product development.

The purpose of this macro study is to identify and analyze the potentials, problems, and the limiting factors, and the needs of the regency; and to recommend the programs and models required by the community to achieve the sustainable development. This research uses the Participatory Rural Appraisal method, the  interview techniques (Semi Structured Interview, the technique of focused group discussion (FGD, the Rapid District Appraisal (RDA, then it is analyzed by the empirical and dynamical systems. The overview of macro studies is particularly relevant in developing the regions, especially the rural areas, based on the existing advantages, such as in Tabanan Regency. Tabanan Regency is a granary in Bali Province and the zoning of agricultural commodities in quadrant III,which is the rural farming area with combined functions between the cultivated and rural areas supported by the tourism department. The studies of the areas in the form of potential analysis, problem analysis, requirement analysis become the guidelines for preparing the development scenarios and program formats. The studies will then constitute the factors driving the realization of sustainable development of tourism villages in supporting the sustainable agriculture.

The findings set the stage for further analysis of decision making in GPD......Global Product Development (GPD), outsourcing and offshoring of product development is a widespread phenomenon on today’s global economy, and consequently most engineering manufacturing companies will have to make decisions regarding how to organise their product development activities globally....... This paper investigates decision making in the GPD context, partly by summarizing existing literatures and studies in the field, and partly through a case study of decision making processes in a global engineering company. Through interviews a range of GPD decisions were mapped and analysed in order...

    Microfluidic devices can better control cellular microenvironments compared to conventional cell migration assays. Over the past few years, microfluidics-based chemotaxis studies showed a rapid growth. New strategies were developed to explore cell migration in manipulated chemical gradients. In addition to expanding the use of microfluidic devices for a broader range of cell types, microfluidic devices were used to study cell migration and chemotaxis in complex environments. Furthermore, high-throughput microfluidic chemotaxis devices and integrated microfluidic chemotaxis systems were developed for medical and commercial applications. In this article, we review recent developments in microfluidics-based chemotaxis studies and discuss the new trends in this field observed over the past few years.

    Children enjoy playing games. We can take advantage of this in the designs of computerized tasks that will engage their interest. These designs also serve to advance the study of chronometric measures, such as manual and saccadic reaction times and event related potentials, with young children. The goals of our method development are (1) to allow for comparable tasks across a wide variety of ages, (2) to make possible comparisons of child performance with data gathered in adult cognitive studies, and (3) to help to support inferences about the development of underlying mechanisms. We have designed a battery of computerized tasks in order to study the development of attention functions of alertness, orienting, and executive control during childhood. Our purpose is to describe each of these tasks in detail and present the results that have been obtained so far. The battery was tested using a sample of 5-year-old children as subjects.

  6. Developing Pedagogical Content Knowledge: Lessons Learned from Intervention Studies

    2015-01-01

    Full Text Available Pedagogical content knowledge (PCK is generally accepted as positively impacting teaching quality and student learning. Therefore, research on PCK development in (prospective teachers is highly relevant. Based on a search in three databases (ERIC, PsycInfo, and Web of Science, a systematic review is conducted on intervention studies aiming at PCK development. The research questions are threefold: (1 How are the studies designed? (2 How are the interventions designed? and (3 What elements of interventions contribute to PCK development? The results show that most intervention studies are conducted in math and science education and use a qualitative methodology. Reflection, PCK courses, contact with other teachers, and experiences in educational practice are typically part of effective interventions. The review enables the identification of clear guidelines that may strengthen future research on stimulating PCK.

    2007-10-15

    We have developed a framework that distributes multiple reservoir simulations on a cluster of CPUs for fast and efficient process optimization studies. This platform utilizes several commercial reservoir simulators for flow simulations, an experimental design and a Monte Carlo algorithm with a global optimization search engine to identify the optimum combination of reservoir decision factors under uncertainty. This approach is applied to a well placement design for a field-scale development exercise. The uncertainties considered are in the fault structure, porosity and permeability, PVT, and relative permeabilities. The results indicate that the approach is practical and efficient for performing reservoir optimization studies. (author)

    2015-12-01

    Full Text Available China is establishing itself as a new international aid donor. This study explains China's emerging approach to international development assistance. The paper addresses the question of how far China's understanding of "development" is an appropriate basis for genuinely "win-win" relationships? The paper explores this question by examining China's relationship with Southeast Asia. China is re-emphasising its commitment and partnership credentials with neighbouring states, some of whom have many people living in poverty and as countries are in need of development assistance. The paper identifies key facets of China's approach to international development, examines economic, political and strategic factors underpinning China's approach in Southeast Asia. Adopting a Human Security perspective, it assesses China's development contribution with reference to Cambodia, Laos and Myanmar and highlights popular opposition. The study finds that Chinese trade and investment are making a significant contribution to the region's economic growth. However, the analysis identifies two problems in China's approach, an over-reliance on the level of state-to-state relations and too narrow a domain of engagement centred upon economic cooperation. China needs to incorporate a societal engagement strategy highlighting transparency and accountability of Chinese corporate behaviour. It also needs to re-balance its approach by emphasising human capital capability and capacity-building across the non-economic social and cultural domains. China's approach to international development is a rapid learning process and is emerging, but still has further to go.

  12. Advanced mathematical study and the development of conditional reasoning skills.

    Directory of Open Access Journals (Sweden)

    Nina Attridge

    Full Text Available Since the time of Plato, philosophers and educational policy-makers have assumed that the study of mathematics improves one's general 'thinking skills'. Today, this argument, known as the 'Theory of Formal Discipline' is used in policy debates to prioritize mathematics in school curricula. But there is no strong research evidence which justifies it. We tested the Theory of Formal Discipline by tracking the development of conditional reasoning behavior in students studying post-compulsory mathematics compared to post-compulsory English literature. In line with the Theory of Formal Discipline, the mathematics students did develop their conditional reasoning to a greater extent than the literature students, despite them having received no explicit tuition in conditional logic. However, this development appeared to be towards the so-called defective conditional understanding, rather than the logically normative material conditional understanding. We conclude by arguing that Plato may have been correct to claim that studying advanced mathematics is associated with the development of logical reasoning skills, but that the nature of this development may be more complex than previously thought.

  15. A model of deep ecotourism development and its empirical study

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Ecotourism requires the harmony of all factors involved in tourism system for a multilateral benefit.Based on such cognition,a concept of deep ecotourism development is put forward which includes two connotations:on the one hand,it should give prominence to the display of the eco-culture of the tourist destination and tourists'eco-experience.in which way the development behavior on the tourist destination and the tourists' behavior will beregulated;on the other hand,it implies the deep harmony among tourist entrepreneurs and tourists,the local governments and the local residents,as well as tourist activities and the ecological environment in the tourism development for the multilateral benefit of every element involved and sustainable tourism development.The common sense is that the degrees in a certain tourism destination will differ and that consequently four levels of ecotourism are divided-very shallow ecotourism,shallow ecotourism,deep ecotourism and very deep ecotourism.To move shallow ecotourism toward deep one,two models of"foursubjects and two wings"and"connecting the two wings"of deep ecotourism development system are introduced to make ecotourism industry favorable to the display of eco-culture and the Sustainable development of the destination community.With the two models,a case study of ecotourism development in Louguantal National Forest Park was made as a demonstration.The ultimate purpose is to build an ideal new Shangri-La.

  16. Student nurses’ needs for developing basic study skills

    Directory of Open Access Journals (Sweden)

    M Fischer

    2001-09-01

    Full Text Available One of the key responsibilities of the nurse educator is to develop student nurses’ abilities regarding self-directed study. Self-directed study requires inter alia, the ability to find information, synthesis and consequent application and integration of the information in practice. The development of the abovementioned skills does not only imply a multidimensional approach to the student in totality, but also requires the meticulous involvement of the student in her/his own learning. The latter also assumes that students possess certain essential skills relevant to learning and studying. From the literature it is evident that secondary schooling in general, does not prepare students adequately for tertiary education. This research intended to find answers to the questions whether student nurses require guidance regarding the development of specifically identified study skills, the guidance provided and whether the guidance provided was sufficient. A descriptive survey was done in order to address the above questions. The research instruments (questionnaires were completed (during 1997 by nurse educators and student nurses in the Western Cape. On completion of the analysis and interpretation of the data, the researcher concluded that student nurses expressed a need for more guidance regarding the development of basic study skills ant that existing student support programs did not address all these needs adequately. Furthermore, it was concluded that the language medium of the prescribed study material had a profound effect on the learning and study proceses of student nurses. Based on the conclusion, various recommendations were made concerning different facets of the teaching/learning event., in order to enhance students’ learning and studying skills. Mastery of these skills can be regarded as being important prerequisites for effective, responsible, independent professional practice.

  18. Towards the Importance for Sustainable Development: Case Study: Albania

    Directory of Open Access Journals (Sweden)

    Klodiana Gorica

    2015-05-01

    Full Text Available Information has become an important element without which society cannot achieve its objectives. The term “information society” is increasingly used nowadays, because of the importance and necessity of information in today's dynamic environment. Western countries are convinced that the information society will result in economic and social benefits (Audenhove 2000. Organization for Economic Cooperation and Development (OECD, notes that information infrastructures are expected to stimulate economic growth, increase productivity, create jobs, and improve on the quality of life (Gichoya 2005. It is for these reasons that many studies state that the role of ICTs as enablers of sustainable development is growing. The overall goal of this paper is to point out the importance of ICT market development for the sustainable development of all the economy and the final development of Information society, especially in developing countries, where Albania is the case study illustration. The first step of this research is to show the importance of studying ICTs in the light of building an information society. In fact, the efforts of a country to build an information society, in order to benefit in terms of sustainable development, are closely related to the efforts of building strong information infrastructures and a growing ICT sector. Many indicators related to Information society measurement deal in fact with the infrastructures needed and the products and services of ICT sector. But, failures to submit ICT in contexts which are contrary to techno-economic rationality are reflected in many cases in developing countries. Thus, a defining characteristic of this research is to understand the contexts that confront ICT and information systems development in developing countries in terms of their conditions. In fact the development of ICT sector, depend not only on the political, economic and social conditions of each country, but also on the phase of e

  19. Pluripotent stem cells for the study of CNS development

    Directory of Open Access Journals (Sweden)

    Timothy J. Petros

    2011-10-01

    Full Text Available The mammalian central nervous system is a complex neuronal meshwork consisting of a diverse array of cellular subtypes generated in a precise spatial and temporal pattern throughout development. Achieving a greater understanding of the molecular and genetic mechanisms that direct a relatively uniform population of neuroepithelial progenitors into the diverse neuronal subtypes remains a significant challenge. A firmer knowledge of the fundamental aspects of developmental neuroscience will allow us to better study the vast array of neurodevelopmental diseases. The advent of stem cell technologies has expedited our ability to generate and isolate populations of distinct interneuron subtypes. To date, researchers have successfully developed protocols to derive many types of neural cells from pluripotent stem cells, with varying degrees of efficiencies and reproducibility. The stem cell field is devoted to the potential of stem cell-derived neurons for the treatment of disease, highlighted by the ability to create patient specific induced pluripotent stem cells. However, another application that is often overlooked is the use of stem cell technology for studying normal neural development. This is especially important for human neurodevelopment, since obtaining embryonic tissue presents numerous technical and ethical challenges. In this review, we will explore the use of pluripotent stem cells for the study of neural development. We will review the different classes of pluripotent stem cells and focus on the types of neurodevelopmental questions that stem cell technologies can help address. In addition to covering the different neural cells derived from stem cells to date, we will detail the derivation and characterization of three of the more thoroughly studied cell groups. We hope that this review encourages researchers to develop innovative strategies for using pluripotent stem cells for the study of mammalian, and specifically human

    2016-10-01

    Full Text Available This paper argues that understanding what is offered as professional development frames what matters in English language teaching in a national education system. Analyzing these offerings articulates the values and perceptions of the work environment in which teachers live professionally. The Learning4Teaching (L4T project is a multi-country series of national studies that examine public-sector English language teachers’ experiences of professional development. The studies document 1 the learning opportunities provided in the national context, 2 how teachers view participating in these opportunities, and 3 what they believe they take from them. Drawing on data from the first phase of the study (#1 above, this paper examines the provision of professional development to ELT teachers in the ‘independent’ (public school sector in Qatar between 2012 and 2015. Of the 150 events offered during this period, 50% concerned teaching methodology. The university/training center sector provided the bulk of professional development (79% of events. The professional development offerings presented teachers with a view of English language teaching as: highly focused on methodological expectations and skills; driven by a set of policy priorities around managing the learning environment, assessment, and standards; in which methodological knowledge and skills are seen as the currency of a teaching identity.

  1. Change over Time: Conducting Longitudinal Studies of Children's Cognitive Development.

    Science.gov (United States)

    Grammer, Jennie K; Coffman, Jennifer L; Ornstein, Peter A; Morrison, Frederick J

    2013-10-01

    Developmental scientists have argued that the implementation of longitudinal methods is necessary for obtaining an accurate picture of the nature and sources of developmental change (Magnusson & Cairns, 1996; Morrison & Ornstein, 1996; Magnusson & Stattin, 2006). Developmentalists studying cognition have been relatively slow to embrace longitudinal research, and thus few exemplar studies have tracked individual children's cognitive performance over time and even fewer have examined contexts that are associated with this growth. In this article we first outline some of the benefits of implementing longitudinal designs. Using illustrations from existing studies of children's basic cognitive development and of their school-based academic performance, we discuss when it may be appropriate to employ longitudinal (versus other) methods. We then outline methods for integrating longitudinal data into one's research portfolio, contrasting the leveraging of existing longitudinal data sets with the launching of new longitudinal studies in order to address specific questions concerning cognitive development. Finally, for those who are interested in conducting longitudinal investigations of their own, we provide practical on-the-ground guidelines for designing and carrying out such studies of cognitive development.

    Full Text Available To create computarization target software as a component system has been a very strong requirement for the last 20 years of software developing. Finally, the architectural components are self-contained units, presenting not only partial and overall system behavior, but also cooperating with each other on the basis of their interfaces. Among others, components have allowed flexible modification of processes the behavior of which is the foundation of components behavior without changing the life of the component system. On the other hand, the component system makes it possible, at design time, to create numerous new connections between components and thus creating modified system behaviors. This all enables the company management to perform, at design time, required behavioral changes of processes in accordance with the requirements of changing production and market.The development of software which is generally referred to as SDP (Software Development Process contains two directions. The first one, called CBD (Component–Based Development, is dedicated to the development of component–based systems CBS (Component–based System, the second target is the development of software under the influence of SOA (Service–Oriented Architecture. Both directions are equipped with their different development methodologies. The subject of this paper is only the first direction and application of development of component–based systems in its object–oriented methodologies. The requirement of today is to carry out the development of component-based systems in the framework of developed object–oriented methodologies precisely in the way of a dominant style. In some of the known methodologies, however, this development is not completely transparent and is not even recognized as dominant. In some cases, it is corrected by the special meta–integration models of component system development into an object methodology.This paper presents a case study

    Turner v, John; Wosnik, Martin

    2014-11-01

    Results from an experimental study of an array of up to 100 model wind turbines with 0.25 m diameter, conducted in the turbulent boundary layer of the 6.0 m wide × 2.7 m tall × 72.0 m long test section of the UNH Flow Physics Facility, are reported. The study aims to address two questions. First, for a given configuration (turbine spacing, initial conditions, etc.), when will the model wind farm reach a ``fully developed'' condition, in which turbulence statistics remain the same from one row to the next within and above the wind turbine array. Second, how is kinetic energy transported in the wind turbine array boundary layer (WTABL). Measurements in the fully developed WTABL can provide valuable insight to the optimization of wind farm energy production. Previous experimental studies with smaller model wind farms were unable to reach the fully developed condition. Due to the size of the UNH facility and the current model array, the fully developed WTABL condition can be achieved. The wind turbine array was simulated by a combination of drag-matched porous disks, used in the upstream part of the array, and by a smaller array of realistic, scaled 3-bladed wind turbines immediately upstream of the measurement location.

    Alturki, Uthman T.

    The goal of this research was to research, design, and develop a hypertext program for students who study biology. The Ecology Hypertext Program was developed using Research and Development (R&D) methodology. The purpose of this study was to place the final "product", a CD-ROM for learning biology concepts, in the hands of teachers and students to help them in learning and teaching process. The product was created through a cycle of literature review, needs assessment, development, and a cycle of field tests and revisions. I applied the ten steps of R&D process suggested by Borg and Gall (1989) which, consisted of: (1) Literature review, (2) Needs assessment, (3) Planning, (4) Develop preliminary product, (5) Preliminary field-testing, (6) Preliminary revision, (7) Main field-testing, (8) Main revision, (9) Final field-testing, and (10) Final product revision. The literature review and needs assessment provided a support and foundation for designing the preliminary product---the Ecology Hypertext Program. Participants in the needs assessment joined a focus group discussion. They were a group of graduate students in education who suggested the importance for designing this product. For the preliminary field test, the participants were a group of high school students studying biology. They were the potential user of the product. They reviewed the preliminary product and then filled out a questionnaire. Their feedback and suggestions were used to develop and improve the product in a step called preliminary revision. The second round of field tasting was the main field test in which the participants joined a focus group discussion. They were the same group who participated in needs assessment task. They reviewed the revised product and then provided ideas and suggestions to improve the product. Their feedback were categorized and implemented to develop the product as in the main revision task. Finally, a group of science teachers participated in this study by reviewing

  10. Institutions and national development in Latin America: a comparative study.

    Science.gov (United States)

    Portes, Alejandro; Smith, Lori D

    We review the theoretical and empirical literatures on the role of institutions on national development as a prelude to present a more rigorous and measurable definition of the concept and a methodology to study this relationship at the national and subnational levels. The existing research literature features conflicting definitions of the concept of "institutions" and empirical tests based mostly on reputational indices, with countries as units of analysis. The present study's methodology is based on a set of five strategic organizations studied comparatively in five Latin American countries. These include key federal agencies, public administrative organizations, and stock exchanges. Systematic analysis of results show a pattern of differences between economically-oriented institutions and those entrusted with providing basic services to the general population. Consistent differences in institutional quality also emerge across countries, despite similar levels of economic development. Using the algebraic methods developed by Ragin, we test six hypotheses about factors determining the developmental character of particular institutions. Implications of results for theory and for methodological practices of future studies in this field are discussed.

  11. Communication and Organization in Software Development: An Empirical Study

    Science.gov (United States)

    Seaman, Carolyn B.; Basili, Victor R.

    1996-01-01

    The empirical study described in this paper addresses the issue of communication among members of a software development organization. The independent variables are various attributes of organizational structure. The dependent variable is the effort spent on sharing information which is required by the software development process in use. The research questions upon which the study is based ask whether or not these attributes of organizational structure have an effect on the amount of communication effort expended. In addition, there are a number of blocking variables which have been identified. These are used to account for factors other than organizational structure which may have an effect on communication effort. The study uses both quantitative and qualitative methods for data collection and analysis. These methods include participant observation, structured interviews, and graphical data presentation. The results of this study indicate that several attributes of organizational structure do affect communication effort, but not in a simple, straightforward way. In particular, the distances between communicators in the reporting structure of the organization, as well as in the physical layout of offices, affects how quickly they can share needed information, especially during meetings. These results provide a better understanding of how organizational structure helps or hinders communication in software development.

  13. Photosynthetic membrane development studied using picosecond fluorescence kinetics

    Karukstis, K.K.; Sauer, K.

    1983-01-01

    Using measurements of the kinetics of chlorophyll a fluorescence emission, the development of the photosynthetic membrane during etioplast-to-chloroplast differentiation was investigated. Tthe chlorophyll fluorescence decay kinetics of pea chloroplasts from plants grown under intermittent (2 min light-118 min dark) and continuous light regimes were monitored with a single-proton timing system with picosecond resolution. The changes in the fluorescence yields and decay kinetics were associated with known structural and organizational developmental phenomena in the chloroplast. This correlation provides a more detailed assignment of the origins of the fluorescence decay components than has been previously obtained by studying only mature chloroplasts. In particular, the analysis of the variable kinetics and multiexponential character of the fluorescence emission during thylakoid development focuses on the organization of photosynthetic units and the degree of communication between reaction centers in the same photosystem. These results further demonstrate that the age of etiolated tissue is critical to plastid development.

    2014-07-01

    Full Text Available Recently, more and more universities are focusing on short-term study abroad programs. However, the actual advantages of such programs have not yet been empirically tested. The primary purpose of this study is to investigate whether such study abroad programs can influence participants and improve an individual’s intercultural competence. Using both reflections found in journals and follow-up interviews, the study aims to reflect the key factors that contribute to the intercultural development of the study participants. This paper elicits and examines the students’ study abroad experiences, particularly in the minimal impacts on the levels of intercultural competence and results of the 2011 summer study abroad program. It is hoped that future study abroad programs will find that this new approach can not only help college students learn better but that it will also shed light on the importance of intercultural competence through dialogue. Further studies are recommended with respect to the duration of the study abroad programs and the quantity/quality of the various activities involved in the enhancement of the students’ intercultural competence.

    Genetically modified (GM) animals can be classified into two groups, those developed for food purposes and those developed not for food purposes. We investigated the recent status of development of GM animals developed not for food purposes. Among the GM animals developed not for food purposes, GM fish, chickens, and pigs were selected because many articles have been published on these organisms. Relevant articles published between 2008 and 2011 were surveyed using PubMed and transgenic fish, chicken, or pig as keywords. Then, studies on organisms that could potentially contaminate the food chain with products from these GM animals were selected and analyzed. Fifteen articles on GM fish were found. These articles were classified into four categories: bioreactor (n = 4), resistance to microorganisms (n = 6), resistance to environmental stresses (n = 1), and detection of chemicals (n = 4). Zebrafish were used in 8 of the articles. Six, three, and three articles were reported from Taiwan, Canada and China. Seven articles on GM chickens were found. These articles were classified into two categories: bioreactor (n = 5), and resistance to pathogens (n = 2). Two articles were reported from Japan and Korea, each. As for GM pigs, 43 articles were found. These articles were classified into three categories: xenotransplantation (n = 36), bioreactor (n = 6), and environmental cleanup (n = 1). Nineteen, seven, six, and five articles were reported from USA, Germany, Korea and Taiwan, respectively. Understanding the recent development of GM animals produced not for food purpose is important for assuring the safety of food.

    1978-09-29

    In response to a widely expressed need to examine the impact of the federal regulatory system on the rate of geothermal power development, the Department of Energy-Division of Geothermal Energy (DGE) has established a Streamlining Task Force in cooperation with appropriate federal agencies. The intent is to find a way of speeding development by modification of existing laws or regulations or by better understanding and mechanization of the existing ones. The initial focus was on the leasing and development of federal lands. How do the existing processes work? Would changes produce positive results in a variety of cases? These are questions which must be considered in a national streamlining process. This report presents case studies of federal leasing actions on seven diverse locations in the western region. Characteristics of existing high geothermal potential areas are quite diverse; geography, environment, industry interest and the attitudes and activities of the responsible federal land management agencies and the interested public vary widely. Included are descriptions of post and current activities in leasing exploration and development and discussions of the probable future direction of activities based on current plans. Implications of these plans are presented. The case studies were based on field interviews with the appropriate State and District BLM officer and with the regional forester's office and the particular forest office. Documentation was utilized to the extent possible and has been included in whole or in part in appendices as appropriate.

    2015-12-01

    Full Text Available This is a research into the assessment of tourism industry quality and programing for its development in Iran. In a tough economic situation, the hypothesis is to grow and develop the national economy with the help of the tourism industry. A unified assessment of tourism industry quality, method is made use of in this study, which is based on the case study of all elements of Iran tourism industry system. Quality assessment by means of unified problems (indicators that hinder the maximum development of the tourism industry shows the reliability of the hypothesis. SWOT analysis aided to determine the weaknesses and threats aiming at raising the quality of the indicators. In addition, a linear programming from the standpoint of internal and external relations with national economy has been applied. The analysis revealed that the system of the tourism industry is unable to assist the macro economy. The failure corresponds to scarcely favorable natural environmental conditions, capacity for motivating to visitors, tourism marketing, and tourism infrastructures. After remedy actions, prospects for tourism industry development despite the complicated situation are quite favorable due to the advantageous climate, natural characteristics, cultural and ancient heritages, tourism resources, and educated labor. The methods applied by this paper suggest adaptive governance tools suitable to apply for optimization of the tourism industry everywhere similar to Iran.

    2012-06-01

    Full Text Available The combination of advanced neuroimaging techniques and major developments in complex network science, have given birth to a new framework for studying the brain: connectomics. This framework provides the ability to describe and study the brain as a dynamic network and to explore how the coordination and integration of information processing may occur. In recent years this framework has been used to investigate the developing brain and has shed light on many dynamic changes occurring from infancy through adulthood. The aim of this article is to review this work and to discuss what we have learned from it. We will also use this body of work to highlight key technical aspects that are necessary in general for successful connectome analysis using today’s advanced neuroimaging techniques. We look to identify current limitations of such approaches, what can be improved, and how these points generalize to other topics in connectome research.

    Atenolol [4-(2-hydroxy-isopropylaminopropoxy)-phenylacetamide], is a cardioselective beta1-adrenergic receptor blocking agent prescribed for treatment of hypertension, angina pectoris and cardiac arrhythmias. However, most of these medicines are not formulated for easy or accurate administration to children. Atenolol is unstable in solutions and therefore the development of a liquid dosage form is a significant challenge. Studies showed that the degradation rate of atenolol is dependent on the temperature, indicating higher stability at 4 degrees C. Atenolol syrup is stable for 9 days, with acceptable apearance. A second order model adequately described atenolol decomposition when stored as syrup. A stability-indicating method was developed and validated in order to evaluate these studies.

    This is a final report for the Phase II study entitled ``Ripeness Sensor Development.`` The overall objective of the study was the development of a prototype device capable of testing whole fruits for sugar content. Although ripeness and sugar content are not synonymous, they are closely related. Furthermore, the consumer`s acceptance of or preference for fruits is strongly influenced by sugar content. Therefore, the device was called a ripeness sensor. The principle behind the measurement is proton magnetic resonance ({sup 1}H-MR). For several decades, chemists, pharmacists and other scientists have been using {sup 1}H-MR to investigate chemical structure and composition. More recently, the technique has been used in laboratories of the food industry for quality control. This effort represents one of the first attempts to adapt {sup 1}H-MR to use in a commercial facility. 28 refs., 36 figs., 7 tabs.

    The connections between people, parks, and tourism have received significant attention in recent years, recognizing the potential for mutually beneficial relationships. Ecotourism has been promoted and widely adopted as a strategy for funding conservation initiatives, while at the same time contributing to the socioeconomic development of host communities and providing for quality tourism experiences. Parks are among the most common ecotourism destinations. Employing interviews, observations and secondary sources, this study assesses the current status of ecotourism at two protected areas in Hainan, China, where it is being promoted as a strategy for balancing regional economic growth and conservation objectives. Through an evaluation of the existing tourism-park-community relationships, opportunities and constraints are identified. Ecotourism development was found to be at an early stage at both study sites. Socioeconomic benefits for the local communities have been limited and tourism activity has not contributed revenues towards conservation to date. Community residents, nevertheless, generally support conservation and are optimistic that tourism growth will yield benefits. In light of the study findings and the salient literature, planning direction is offered with the intention of enhancing the capacity of ecotourism to generate benefits for both communities and the parks, and thus contribute to the sustainable development of the region more generally. Lessons derived have broad applicability for ecotourism destinations elsewhere.

  10. Three Critical Issues in Sustainable Development Studies and the Transition Development of China

    Institute of Scientific and Technical Information of China (English)

    Zhu Dajian

    2012-01-01

    The core issue for China transition development in the next 30 years is to shift from the quantity growth model to the quality improvement model. The paper introduces the research progress in three key areas of sustainable development studies since the 1990s. It is pointed out that there is a well-being thresh- old at which the margin utility of economic growth for human well-being will decline, that there is an ecological limit beyond which more economic growth in terms of physical scale will be impossible, and that the creation of human well-being is related not only to the amount but also to the structure and efficiency of public expenditure from government. After an in-depth discussion on facts, origins and policy implications of each issue, some theory and policy thinking with long-lasting significance are raised for the transition development of China.

The study is an ongoing multi-disciplinary longitudinal study which follows the lives of around 17,000 people born in England, Scotland and Wales in a single week of 1958. Over the course of cohort members lives, the NCDS has collected information on health, physical, educational and social development, and economic circumstances among other factors. The broad aim of the study is to examine the impact that circumstances and experiences at one stage of life have on outcomes and achievements in later life. Since the birth survey in 1958, there have been ten ‘sweeps’ of all cohort members at ages 7, 11, 16, 23, 33, 42, 44/5 (a biomedical collection 46, 50 and most recently at 55. Data has been collected from a number of different sources (the midwife present at birth, parents of the cohort members, teachers, doctors and the cohort members themselves. The data has been collected in a variety of ways including via paper and electronic questionnaires, clinical records, medical examinations, physical measurements, tests of ability and educational assessments. The information collected forms a high quality data resource for scientific investigations across a full range of domains of individuals’ lives and across different points in time in them. The study has been designed so as to ensure comparability with other major cohort studies so as permit the examination of links between social change and the changing experiences of different cohorts. The majority of NCDS survey data can be accessed by bona fide researchers through the UK Data Service at the University of Essex.

    Full Text Available This research investigated the effect of a five stage study program applied by the researcher to one student who had entered university playing the flute, but who had not resolved lip and tone problems in one educational semester through basic long sound studies and scale studies. The participant in the research was a 19 year old student who had completed first year of the music teaching program and had performed in the year-end concert; however she was criticized by listeners and flute teachers for forced and scratchy tone. The research had the basic aim of solving these problems. As a result the “single subject study model”, chosen for research on individuals requesting private training, was chosen for this research model. The findings of the study were collected as video recordings of scale, study and piece work in initial, training and final stages of a six-week education course run every day. To evaluate the obtained recordings, a “Behavior for Quality Flute Tone Scale” was created. The video recordings were investigated by three flute teaching staff, expert in the area, who provided points in accordance with the scale. The obtained points were analyzed using the SPSS 15.0 program. The results showed that the study program created by the researcher provided rapid tonal development of the student. It is considered that the study is important to present an alternative route for flute students experiencing similar problems.

    Knowledge products such as clinical practice guidelines (CPG) are vitally required for evidence-based medicine (EBM). Although the EBM, to some extent, has been attended during recent years, no result has achieved thus far. The current qualitative study is to identify the barriers to establishing development system and implementation of CPGs in Iran. Twelve semi-structured, in-depth interviews were conducted with a purposive sample of health policy and decision makers, the experts of development and or adaptation of CPGs, and the experts of EBM education and development. In addition, 11 policy-makers, decision-makers, and managers of the health system participated in a focus group discussion. The analysis of the study data was undertaken by thematic framework approach. Six themes emerged in order of their frequency include practice environment, evidence-based health care system, individual professional, politician and political context, innovation (CPG) and patients. Most of the indications in the treatment environment focused on such sub-themes as regulations and rules, economical factors, organizational context, and social context. While the barriers related to the conditions of treatment environment, service provider and the features of innovation and patients had been identified before in other studies, very little attention has been paid to the evidence-based health care system and politician and political context. The lack of an evidence-based healthcare system and a political macro support are mentioned as the key barriers in Iran as a developing country. The establishment of a system of development and implementation of CPGs as the evidence-based practice tools will not be possible, unless the barriers are removed.

    In response to increasing recognition of the importance of quality health care work environments, the Alberta Cancer Board initiated a province-wide leadership development program to plan for organizational change through a series of stages. In 2004, the Leadership Development Initiative (LDI) was implemented to facilitate organizational learning using a cohort-based leadership intervention based on a communities of practice framework. The aim of the Worklife Improvement and Leadership Development study was to examine both the outcomes and experiences of participants of the LDI program to better understand leadership development, implementation, and its impact on worklife quality among 5 cohorts of health care managers and staff at the Alberta Cancer Board. This study used both structured survey and interview methods, using a pretest-intervention-posttest quasi-experiment without a control group design, to assess the effects of LDI on worklife of leaders and staff. Surveys included the Leadership Practices Inventory and Areas of Worklife Scale, which looked at meaningfulness of work and organizational engagement. Interviews and focus group data provided a more detailed description of the experience of leadership development and perceptions of organizational worklife. The study revealed layers of information about the complexity of individual and collective leadership in a cohort-based design, perceptions of leadership initiatives, organizational worklife, and planned organizational change. Our findings suggest that early changes in how leaders reflected on their own skills and practices (Leading Self) were positive; however, growing disengagement as the LDI continued was evident in the focus group data, particularly when change in behavior of others was not perceived to be evident. To support the effectiveness and success of a leadership initiative, managers and administrators need to implement strategies designed to help leaders grow and cope with ongoing flux of

    This paper investigates the global nanotechnology and nanoscience (NN) indicators in a developmental context, during three 5-year periods from 2000 to 2014. Through bibliometric analyses of the longitudinal data from well-known databases, the growth patterns of NN articles and patents were investigated. Furthermore, the causal relationships among these indicators and some characteristics of the 105 countries studied were examined using regression and correlation analyses leading to the identification of the top 20 "science and innovation giants," in terms of all indicators, as well as the existence of significant, yet different, correlations among the indicators in developing and developed countries. In general, China's growth rate (GR) in NN publications was found to surpass USA, from 2010 to 2014, leading to a change in the ranking of the top countries and moving China, with about 25 % of world's NN articles, to top. A different trend was distinguished for patents in the area of nanotechnology, where USA, as the origin of over half of the world's granted patents, has been the undisputed leader. The shares of developing countries (i.e., the percent ratios of the number of nanotech patents granted to the citizens of developing countries over the total number of nanotech patents granted worldwide) was found to be incompatible with the countries' shares in the total NN articles, indicating a poor correlation between the two factors. However, developing countries were found to be superior in the GR of both NN articles and patents. Finally, the top countries identified can be regarded as suitable for comparative studies, and benchmarking by researchers and policy makers.

    Full Text Available The common purposes of the studies conducted in language program evaluations are to examine the match between what is desired for the programme versus the actual state of the programme, to make judgments about learners’ level of skills and knowledge, and to make suggestions for improvement. However, it is not currently common practice in Turkey either to develop language teaching programmes based on the Common European Framework as a reference, or to introduce improvements in these programmes based on an evaluation of their effectiveness. This study aims to describe the process of developing a new teaching programme, taking CEF into consideration, at the Preparatory Programme at the School of Foreign Languages, Izmir University of Economics, and also to evaluate the effectiveness of the programme. 236 Freshman students and 48 faculty members from 5 different faculties participated in the study. The results indicated a significant relationship between students’ proficiency scores and perception of their own competencies and a significant difference in perception of their own competence in terms of levels at the preparatory program. Although faculty members stated that Preparatory Program, in general, meets the needs of the students, students still have difficulty in practising some tasks requiring higher order thinking skills. The study suggests a series of learner training sessions to raise the awareness of the students, extending duration of the modules, reviewing the order of objectives in Intermediate and Upper-Intermediate, and working in cooperation with Faculties in order to increase awareness of mutual expectations.

    During the development of the nervous system, neurons migrate and grow over great distances. Currently, our understanding of nervous tissue development is, in large part, based on studies of biochemical signaling. Despite the fact that forces are involved in any kind of cell motion, mechanical aspects have so far rarely been considered. Here we used deformable cell culture substrates, traction force microscopy and calcium imaging to investigate how neurons probe and respond to their mechanical environment. While the growth rate of retinal ganglion cell axons was increased on stiffer substrates, their tendency to grow in bundles, which they show in vivo, was significantly enhanced on more compliant substrates. Moreover, if grown on substrates incorporating linear stiffness gradients, neuronal axons were repelled by stiff substrates. Mechanosensing involved the application of forces driven by the interaction of actin and myosin II, and the activation of stretch-activated ion channels leading to calcium influxes into the cells. Applying a modified atomic force microscopy techniquein vivo, we found mechanical gradients in developing brain tissue along which neurons grow. The application of chondroitin sulfate, which is a major extracellular matrix component in the developing brain, changed tissue mechanics and disrupted axonal pathfinding. Hence, our data suggest that neuronal growth is not only guided by chemical signals - as it is currently assumed - but also by the nervous tissue's mechanical properties.

    A project was proposed by EnCana Corporation (EnCana) for the development of the Deep Panuke Offshore Gas Development Project. Located offshore the Scotian Shelf, approximately 175 kilometres southeast of Goldboro, Nova Scotia and 250 kilometres southeast of Halifax, the development of this natural gas reservoir would allow EnCana to derive economic benefit from licences issued under the Canada-Nova Scotia Offshore Petroleum Resources Accord Implementation Act and the Canada-Nova Scotia Offshore Petroleum Resources Accord Implementation (Nova Scotia) Act. The Canadian Environmental Assessment Act required that a comprehensive study report be prepared, and the results were presented in this document. Consisting of three bottom-founded platforms in a water depth of approximately 40 metres, the wellhead platform would be used for dry wellheads, wellhead control system, and production manifolds. All power generation and processing equipment would be located on the production platform, and the accommodations platform would consist of the utilities, helicopter landing pad, refueling station and crew accommodations. It was determined that the Deep Panuke project was unlikely to result in adverse environmental effects. The offshore oil and gas industry in Atlantic Canada would benefit from this development as a result of the establishment of a viable facility and operation.

    The Interfood v. 1.3 software program was developed to process nutrition information and generate data on dietary intakes--in terms of food, nutrients, and phytochemical substances--valid for conducting studies on nutrition and epidemiology. The program has three basic components: the dietary intake frequency questionnaire CFCA); a database of common foods and their composition of 131 possible substances (macro- and micronutrients and phytochemicals); and a relational database that links the CFCA data with the food database. In this manner, the Interfood software program calculates the amount of food, nutrients, and phytochemical substances consumed by an individual daily, weekly, and monthly. Interfood is an open-source program; as such, the database can be modified and updated according to study requirements. This program has already proven useful to various studies of nutrition and epidemiology.

    This study was conducted to develop and pilot test a Korean version of the Family Attitude Scale (FAS). We developed the Korean FAS using the translation/back-translation method. Two English monolinguals assessed its translation validity by comparing the original with a back-translated English version. Translation equivalence of the FAS and the refined Korean FAS was evaluated in a convenience sample of 56 bilingual Korean college students. The internal consistency of the Korean FAS and the FAS was 0.96 and 0.76, respectively. Mean scores on the two versions did not differ (t = -0.14, p = 0.89). The test-retest correlation coefficient was 0.37 (p < .001). Although the Korean FAS needs further refinement and psychometric testing, it was translated to reflect the original version and was a reliable instrument for the Korean population.

    2015-01-01

    Full Text Available This study implemented a mobile diagnosing system that provides user-centered interfaces for more precisely estimating and diagnosing engine conditions through communications with the self-developed ECU only for industrial CRDI engine use. For the implemented system, a new protocol was designed and applied based on OBD-II standard to receive engine data values of the developed ECU. The designed protocol consists of a message structure to request data transmission from a smartphone to ECU and a response message structure for ECU to send data to a smartphone. It transmits 31 pieces of engine condition information simultaneously and sends the trouble diagnostic code. Because the diagnostic system enables real-time communication through modules, the engine condition information can be checked at any time. Thus, because when troubles take place on the engine, users can check them right away, quick response and resolution are possible, and stable system management can be expected.

    Although many medical schools include arts-based activities in their curricula, empirical evidence is lacking regarding how the creation of art might impact medical students and their professional development. We used a qualitative research design in order to understand this process. We conducted and analysed interviews with 16 medical students who had created and presented original artwork in the context of a required narrative-based undergraduate medical education programme. Teams of students collaborated to create interpretive projects based on common themes arising from conversations with individuals with chronic illness and their families. Open-ended questions were utilised to explore the conceptualisation and presentation of the projects, the dynamics of teamwork and the meaning(s) they might have for the students' professional development. We identified themes using repeated contextual reading of the transcripts, which also enhanced accuracy of the interpretations and ensured saturation of themes. Several major themes and sub-themes were identified. The creation of art led to a sense of personal growth and development, including reflection on past life experiences, self-discovery and an awareness of art as a creative outlet. Students also reported an enhanced sense of community and the development of skills in collaboration. Lastly, students reflected on the human dimensions of illness and medical care and identified an enhanced awareness of the experience of those with illness. A programme involving the creation of art based on stories of illness encouraged students' explorations of conceptions of the self, family and society, as well as illness and medical care, while enhancing the development of a collaborative and patient-centred worldview. Creative art can be a novel educational tool to promote a reflective, humanistic medical practice. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    Background: The Early Detection Research Network (EDRN), NCI funded and investigator driven, has the mission to evaluate biomarkers for their clinical utilities in cancer risk prediction, diagnosis, early detection, and prognosis. Abundant cancer biomarkers reported in literature yet few are used in clinics. Therefore, the emphasis of the EDRN is biomarker validation. Although schema for a phased approach to development exists and guidelines are available for study reporting, a coherent and comprehensive set of guideline for a definitive biomarker validation study design have not been delineated.Methods: We proposed PROBE study design, Prospective specimen collec-tion and Retrospective Blinded Evaluation, for pivotal definitive evaluation of the accuracy of a classification biomarker. A detailed formulation of all aspects of the design is provided. Four tables itemize aspects that relate to (i) the Clinical Context; (ii) Performance Criteria; (iii) the Biomarker test; and (iv) Study power and termination. Alternative designs and strategies were contrasted to illustrate the merit of PROBE design.Results: The ideas are applied to studies of biomarkers the intended use of which is for disease diagnosis, screening, or prognosis. Two EDRN valida-tion studies (breast cancer and prostate cancer) were used as examples to elucidate PROBE design.Conclusion: Common biases that pervade the biomarker research literaturewould be eliminated if these rigorous standards were followed closely. We urge the adoption of the design as standard of practice for pivotal evaluation of the classification accuracy ofbiomarkers.

    Severe burn injuries can require escharotomies which are urgent, infrequent, and relatively high-risk procedures necessary to preserve limb perfusion and sometimes ventilation. The American Burn Association Advanced Burn Life Support© course educates surgeons and emergency providers about escharotomy incisions but lacks a biomimetic trainer to demonstrate, practice, or provide assessment. The goal was to build an affordable biomimetic trainer with discrete points of failure and pilot a validation study. Fellowship-trained burn and plastic surgeons worked with special effect artists and anatomists to develop a biomimetic trainer with three discrete points of failure: median or ulnar nerve injury, fasciotomy, and failure to check distal pulse. Participants were divided between experienced and inexperienced, survey pre- and post-procedure on a biomimetic model while being timed. The trainer total cost per participant was less than $35. Eighteen participants were involved in the study. The inexperienced (0-1 prior escharotomies performed) had significantly more violations at the discrete points of failure relative to more experienced participants (P = .036). Face validity was assessed with 100% of participants agreement that the model appeared similar to real life and was valuable in their training. Given the advancements in biomimetic models and the need to train surgeons in how to perform infrequent, emergent surgical procedures, an escharotomy trainer is needed today. The authors developed an affordable model with a successful pilot study demonstrating discrimination between experienced and inexperienced surgeons. Additional research is needed to increase the reliability and assessment metrics.

    Full Text Available Student’s ability to use and manipulate scientific concepts has been widely explored; however there is still a need to define the characteristics and nature of science ability. Also, the tests and performance scales that require minimal conceptual knowledge to measure this ability are relatively less common. The aim of this study was to develop an objective measure of science ability of gifted middle school students. In order to assess this ability, Science Ability Test Battery was developed by the researchers. The test battery was divided into two sub scales containing; a multiple choice questions achievement test (Science Ability Test and a performance assessment (Science Performance Test. The initial Science Ability Test consisted of 23 multiple choice items with one correct answer that required students to use science process skills and reasoning. In the study, stratified sampling was used. The test was administered to 280 middle school students in Turkey and the missing data from 26 students were excluded. In order to obtain a proof of content validity, the researchers elicited feedback from five experts in the field of science education and gifted education and necessary corrections were made in accordance of their views and suggestions. This study will be followed by another research to further analyse validity and reliability of the test.

    Collaborative and international scientific efforts continue to be of increasing importance in the development of successful educational and research programs. The goal of our study abroad program, Neuroscience Seminar in Germany, is to bring this fact to light for undergraduates and make them aware of the global opportunities that exist in the neurosciences and related biological sciences. Here we discuss our experience of conducting a four-week summer study abroad course in collaboration with two universities associated with the German Graduate Schools of Neuroscience: Munich Center for Neurosciences - Ludwig-Maximilians-Universität (MCN-LMU) and Charité - Universitätsmedizin, Berlin (a joint institution of the Freie Universität and the Humboldt-Universität). This course combined the historical foundations of neuroscience in Germany with current research programs at these two prominent German research universities. Two weeks were spent at each location and faculty members from the participating universities provided seminars, laboratory exercises, demonstrations and tours. Students were presented with background reading and lecture material prior to the seminars and activities. Additionally, they were responsible for leading seminar-style class discussions through brief presentations and submitting written critical analyses of primary research papers associated with the laboratory exercises. These assignments provided a means to assess learning outcomes, coupled with course evaluations. Overall, this experience may serve as a template for those interested in study abroad course development and research opportunities in the neurosciences.

    2015-01-01

    Poisonous organisms are represented in many taxa, including kingdom Animalia. During evolution, animals have developed special organs for production and injection of venoms. Animal venoms are complex mixtures, compositions of which depend on species producing venom. The most known and studied poisonous terrestrial animals are snakes, scorpions and spiders. Among marine animals, these are jellyfishes, anemones and cone snails. The toxic substances in the venom ofthese animals are mainly of protein and peptide origin. Recent studies have indicated that the single venom may contain up to several hundred different components producing diverse physiological effects. Bites or stings by certain poisonous species result in severe envenomations leading in some cases to death. This raises the problem of bite treatment. The most effective treatment so far is the application of antivenoms. To enhance the effectiveness of such treatments, the knowledge of venom composition is needed. On the other hand, venoms contain substances with unique biological properties, which can be used both in basic science and in clinical applications. The best example of toxin application in basic science is α-bungarotoxin the discovery of which made a big impact on the studies of nicotinic acetylcholine receptor. Today compositions of venom from many species have already been examined. Based on these data, one can conclude that venoms contain a large number of individual components belonging to a limited number of structural types. Often minor changes in the amino acid sequence give rise to new biological properties. Change in the living conditions of poisonous animals lead to alterations in the composition of venoms resulting in appearance of new toxins. At the same time introduction of new methods of proteomics and genomics lead to discoveries of new compounds, which may serve as research tools or as templates for the development of novel drugs. The application of these sensitive and

    Empirical measurement of interventions to address significant global health and development problems is necessary to ensure that resources are applied appropriately. Such intervention programs are often deployed at the group or community level. The gold standard design to measure the effectiveness of community-level interventions is the community-randomized trial, but the conditions of these trials often make it difficult to assess their external validity and sustainability. The sheer number of community interventions, relative to randomized studies, speaks to a need for rigorous observational methods to measure their impact. In this article, we use the potential outcomes model for causal inference to motivate a matched cohort design to study the impact and sustainability of nonrandomized, preexisting interventions. We illustrate the method using a sanitation mobilization, water supply, and hygiene intervention in rural India. In a matched sample of 25 villages, we enrolled 1,284 children <5 y old and measured outcomes over 12 mo. Although we found a 33 percentage point difference in new toilet construction [95% confidence interval (CI) = 28%, 39%], we found no impacts on height-for-age Z scores (adjusted difference = 0.01, 95% CI = −0.15, 0.19) or diarrhea (adjusted longitudinal prevalence difference = 0.003, 95% CI = −0.001, 0.008) among children <5 y old. This study demonstrates that matched cohort designs can estimate impacts from nonrandomized, preexisting interventions that are used widely in development efforts. Interpreting the impacts as causal, however, requires stronger assumptions than prospective, randomized studies. PMID:21149699

    A model for keratoepithelioplasty (KEP) was developed using the Lewis rat, and histological studies were performed using this model. The entire corneal epithelium was removed mechanically and a 1.5-mm width of the conjunctiva including the limbus was excised. An oval corneal lamellar graft (3 x 1.5 mm) with an intact epithelium taken from another Lewis rat was transplanted on the denuded limbus. Biomicroscopic observations showed much less vascular invasion in the part of the cornea adjacent to the lenticule than in other parts of the cornea, and the cornea remained clear adjacent to the lenticule. Histologically, a few vessels were observed in the corneal stroma under the lenticule. Epithelial cells on the lenticule specimens showed histological characteristics of the corneal epithelium. These findings indicate that one of the functions of KEP is to block neovascularization in the newly developing corneal epithelium by transplanting the lenticule between the corneal epithelium and conjunctival vessels. The present study also confirmed that this model is useful in the research of the pathophysiological mechanism of KEP.

    Adolescence is a unique period of physical and cognitive development that includes concurrent pubertal changes and sex-based vulnerabilities. While diffusion tensor imaging (DTI) studies show white matter maturation throughout the lifespan, the state of white matter integrity specific to adolescence is not well understood as are the contributions of puberty and sex. We performed whole-brain DTI studies of 114 children, adolescents, and adults to identify age-related changes in white matter integrity that characterize adolescence. A distinct set of regions across the brain were found to have decreasing radial diffusivity across age groups. Region of interest analyses revealed that maturation was attained by adolescence in broadly distributed association and projection fibers, including those supporting cortical and brain stem integration that may underlie known enhancements in reaction time during this period. Maturation after adolescence included association and projection tracts, including prefrontal-striatal connections, known to support top-down executive control of behavior and interhemispheric connectivity. Maturation proceeded in parallel with pubertal changes to the postpubertal stage, suggesting hormonal influences on white matter development. Females showed earlier maturation of white matter integrity compared with males. Together, these findings suggest that white matter connectivity supporting executive control of behavior is still immature in adolescence.

    Even though the nuclear society is again facing with difficult situations after Fukusima accident, some countries still continues to consider nuclear power as one option of national energy sources and to introduce nuclear energy. As a research reactor has been regarded as a step-stone to establish infrastructures for the nuclear power development program, some countries that have plan to introduce the nuclear power energy are considering to construct a research reactor. Particularly, a low power research reactor whose main purpose is basic researches on the nuclear technology and education/training would be of interest to developing countries when taking the economy and level of science and technology into consideration. And many low power research reactors at operation are obsolescent and their numbers are decreasing. Hence, some concepts on a low power research reactor are being studied for the future needs. This paper presents the conceptual study on the basic requirements and the preliminary design features of a low power research reactor.

    The goal of this project was to develop improved instrumentation for studying the microscopic structures of materials using neutron scattering. Neutron scattering has a number of advantages for studying material structure but suffers from the well-known disadvantage that neutrons’ ability to resolve structural details is usually limited by the strength of available neutron sources. We aimed to overcome this disadvantage using a new experimental technique, called Spin Echo Scattering Angle Encoding (SESAME) that makes use of the neutron’s magnetism. Our goal was to show that this innovation will allow the country to make better use of the significant investment it has recently made in a new neutron source at Oak Ridge National Laboratory (ORNL) and will lead to increases in scientific knowledge that contribute to the Nation’s technological infrastructure and ability to develop advanced materials and technologies. We were successful in demonstrating the technical effectiveness of the new method and established a baseline of knowledge that has allowed ORNL to start a project to implement the method on one of its neutron beam lines.

    Full Text Available Abstract Objective Few methodological studies address the prioritization of clinical topics for the development of Clinical Practice Guidelines (CPGs. The aim of this study was to validate a methodology for Priority Determination of Topics (PDT of CPGs. Methods and results Firstly, we developed an instrument for PDT with 41 criteria that were grouped under 10 domains, based on a comprehensive systematic search. Secondly, we performed a survey of stakeholders involved in CPGs development, and end users of guidelines, using the instrument. Thirdly, a pilot testing of the PDT procedure was performed in order to choose 10 guideline topics among 34 proposed projects; using a multi-criteria analysis approach, we validated a mechanism that followed five stages: determination of the composition of groups, item/domain scoring, weights determination, quality of the information used to support judgments, and finally, topic selection. Participants first scored the importance of each domain, after which four different weighting procedures were calculated (including the survey results. The process of weighting was determined by correlating the data between them. We also reported the quality of evidence used for PDT. Finally, we provided a qualitative analysis of the process. The main domains used to support judgement, having higher quality scores and weightings, were feasibility, disease burden, implementation and information needs. Other important domains such as user preferences, adverse events, potential for health promotion, social effects, and economic impact had lower relevance for clinicians. Criteria for prioritization were mainly judged through professional experience, while good quality information was only used in 15% of cases. Conclusion The main advantages of the proposed methodology are supported by the use of a systematic approach to identify, score and weight guideline topics selection, limiting or exposing the influence of personal biases

    Full Text Available The present research aims to explore a scale of Corporate Social Responsibility (CSR in Iran. In this way, it reviews the literature exist on corporate social responsibility, gathers data and analyzes the data to test the emerging trends. After confirmation of reliability, factor analysis and multi dimensional scaling are used to an established survey instrument. Finally CSR was achieved as a construct with five dimensions: obligation to employees, obligation to customers and markets, obligation to social programs and natural environment, obligation to laws and regulations and obligation to society. These five dimensions represent the corporate accountability to some different groups of its stakeholders. In this study the convenient samples of managers and employees used in collecting data and developing the scale, however in exploratory studies, this type of sampling can be acceptable. Nevertheless, some limitations should be taken into consideration, while interpreting the findings of the study and generalizing them to general business environment. Therefore enlarging the sample size and using a random sampling method of managers and employees in future studies has to make Corporate Social Responsibility (CSR scale more useful and enhance the generalization.

    Vaccine drug product thermal stability often depends on formulation input factors and how they interact. Scientific understanding and professional experience typically allows vaccine formulators to accurately predict the thermal stability output based on formulation input factors such as pH, ionic strength, and excipients. Thermal stability predictions, however, are not enough for regulators. Stability claims must be supported by experimental data. The Quality by Design approach of Design of Experiment (DoE) is well suited to describe formulation outputs such as thermal stability in terms of formulation input factors. A DoE approach particularly at elevated temperatures that induce accelerated degradation can provide empirical understanding of how vaccine formulation input factors and interactions affect vaccine stability output performance. This is possible even when clear scientific understanding of particular formulation stability mechanisms are lacking. A DoE approach was used in an accelerated 37(°)C stability study of an aluminum adjuvant Neisseria meningitidis serogroup B vaccine. Formulation stability differences were identified after only 15 days into the study. We believe this study demonstrates the power of combining DoE methodology with accelerated stress stability studies to accelerate and improve vaccine formulation development programs particularly during the preformulation stage.

    That there is a need in the world today, and in the Third World in particular, for developing renewable energy sources is a proposition without question. Toward that end, the harnessing of solar energy has attracted much attention recently. In this thesis, we have addressed the question of Photovoltaics among the many approaches to the problem as being of poignant relevance in the Third World. Based on our studies, which involved the physics of solar cells, various solar cell configurations, the materials for their fabrication and their fabrication sequences, we arrived at the conclusion that silicon homojunction solar cells are best suited to the present needs and environment of, and suitable for development in the Third World, though Cadmium Sulphide-Cuprous Sulphide solar cell could be considered as a viable future candidate. Attendant with the adoption of photovoltaics as electric energy supply, is the problem of technology transfer and development. Towards that goal, we carried out in the laboratory, the fabrication of solar cells using very simple fabrication sequences and materials to demonstrate that tolerable efficiencies are achievable by their use. The view is also presented that for a thriving and viable solar cell industry in the Third World, the sine qua non is an integrated national policies involving all facets of solar cell manufacture and application, namely, material processing and fabrication, basic research, and development and socio -economic acceptance of solar cell appliances. To demonstrate how basic research could benefit solar cell fabrication, we undertook a number of experiments, such as varying our fabrication sequences and materials, finding their radiation tolerance, and carrying out Deep Level Transient Spectroscopy (DLTS) studies, in an attempt to understand some of the fabrication and environmental factors which limit solar cell performance. We thus found that subjecting wafers to preheat treatments does not improve solar cell

    In 2000 I reported at this symposium about multi-institutional graduate field trips to IAVCEI events, such as the Bali meeting and its importance in building international collegiality and awareness among the volcanology doctoral students. NSF was an enthusiastic supporter of these field sessions and this support has continued through the highly successful Pucon and Reykjavik sessions. International volcanology graduate program development began with several exchange programs. EHaz was a highly successful program (McGill, Simon Fraser, Michigan Tech, Buffalo, UNAM and Universidad de Colima) funded by the Department of Education (FIPSE) that moved students across North America where dozens of graduate students spent semesters of their study abroad and shared annual field trips and online student led graduate seminar classes. Michigan Tech’s volcanology graduate program started a Masters International program that combined Peace Corps service with hazards mitigation graduate study and students were placed by Peace Corps in countries with prominent natural hazards. The new program funded 2 year residences in foreign environments, principally in Pacific Latin America. NSF strongly supported this program from its inception, and eventually it gained NSF PIRE support. Dozens of students have initiated the 3 year program (15 completed) to date. A similar PIRE developed at UAF with a link to volcanology in the Russian Far East. One gain is the development of many socially-conscious research selections. Beginning this year transatlantic dual degree masters programs in volcanology are being offered by a consortium of US and European volcanology programs (Michigan Tech, Buffalo, Clermont Ferrand and University of Milan Bicocca), again aided by FIPSE funding. Students have dual advisors on both sides of the Atlantic and spend about half of their two year programs in Europe and half in US. Faculty also travel in the program and the four campuses are increasingly linked by

    Project Objective: The Mississippi Band of Choctaw Indians (MBCI) conducted a study of the feasibility of siting a renewable energy biomass-based installation on tribal lands. The purpose of the study was to determine whether such an installation can be economically sustainable, as well as consistent with the cultural, social, and economic goals of the Tribe. Scope: To achieve the goal of the feasibility study, the following tasks were carried out: (1) Resource availability assessment--The objective of this assessment was to determine the availability of both poultry litter and wood residues for use in the proposed facility. (2) Power utilization assessment--The objective of this assessment was to determine the potential market size for power produced, the existing infrastructure for delivering power to that market, and the costs and economic returns for doing so. (3) Technology review--The objective of this review was to identify one, or more, technical options for detailed economic and technical assessment. The study considered a range of feedstock and product mixtures of poultry litter; wood residues as feedstock; and electrical power and other ancillary products as outputs. Distributed power sources was also examined. Technologies ranging from gasification to systems that produce both power and value-added chemicals were considered. Technologies selected for detailed review were those that can be sized to process the amount of available feed (poultry litter, or poultry litter and wood residues), and that also appear to make economic sense in terms of the value of their inputs. The technology review leaned heavily on the experience from similar prior DOE projects, particularly those conducted by the National Renewable Energy Laboratory (NREL). NREL was involved in a consultative role, so that the project team could leverage their experience. (4) Systems Design(s)--Based on the technology review, a pre-conceptual design for an installation was developed. This

    The aim of this study was to develop a screening questionnaire that could distinguish individuals at high risk of smartphone overuse from casual users. The reliability, validity, and diagnostic ability of the Smartphone Overuse Screening Questionnaire (SOS-Q) were evaluated. Preliminary items were assessed by 50 addiction experts on-line, and 28 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. The SOS-Q, Young's internet addiction scale, Korean scale for internet addiction, and Smartphone Scale for Smartphone Addiction (S-Scale) were used to assess the concurrent validity. Construct validity was supported by a six-factor model using an exploratory factor analysis. The internal consistency and the item-total correlations were favorable (α = 0.95, r = 0.35-0.81). The test-retest reliability was moderate (r = 0.70). The SOS-Q showed superior concurrent validity with the highest correlation between the S-Scale (r = 0.76). Receiver operating characteristic curve analysis revealed an area under the curve of 0.877. A cut-off point of 49 effectively categorized addiction high-risk group with a sensitivity of 0.81 and specificity of 0.86. Overall, the current study supports the use of SOS-Q as both a primary and supplementary measurement tool in a variety of settings. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    3D Printers are used to create three-dimensional models based on blueprints. Based on this characteristic, it is feasible to develop a bolus that can minimize the air gap between skin and bolus in radiotherapy. This study aims to compare and analyze air gap and target dose at the branded 1 cm bolus with the developed customized bolus using 3D printers. RANDO phantom with a protruded tumor was used to procure images using CT simulator. CT DICOM file was transferred into the STL file, equivalent to 3D printers. Using this, customized bolus molding box (maintaining the 1 cm width) was created by processing 3D printers, and paraffin was melted to develop the customized bolus. The air gap of customized bolus and the branded 1 cm bolus was checked, and the differences in air gap was used to compare D{sub max}, D{sub min}, D{sub mean}, D{sub 95%} and V{sub 95%} in treatment plan through Eclipse. Customized bolus production period took about 3 days. The total volume of air gap was average 3.9 cm{sup 3} at the customized bolus. And it was average 29.6cm{sup 3} at the branded 1 cm bolus. The customized bolus developed by the 3D printer was more useful in minimizing the air gap than the branded 1 cm bolus. In the 6 MV photon, at the customized bolus, D{sub max}, D{sub min}, D{sub mean}, D{sub 95%}, V{sub 95%} of GTV were 102.8%, 88.1%, 99.1%, 95.0%, 94.4% and the D{sub max}, D{sub min}, D{sub mean}, D{sub 95%}, V{sub 95%} of branded 1 cm bolus were 101.4%, 92.0%, 98.2%, 95.2%, 95.7%, respectively. In the proton, at the customized bolus, D{sub max}, D{sub min}, D{sub mean}, D{sub 95%}, V{sub 95%} of GTV were 104.1%, 84.0%, 101.2%, 95.1%, 99.8% and the D{sub max}, D{sub min}, D{sub mean}, D{sub 95%}, V{sub 95%} of branded 1cm bolus were 104.8%, 87.9%, 101.5%, 94.9%, 99.9%, respectively. Thus, in treatment plan, there was no significant difference between the customized bolus and 1 cm bolus. However, the normal tissue nearby the GTV showed relatively lower radiation dose. The

    Full Text Available Global interest in stable energy resources coupled with growing demand for bio-oils in various conventional and arising industries has renewed the importance of vegetable oil production. To address this global interest, oilseed production has been increased in recent decades by different approaches, such as extending the cultivation area of oil crops, or breeding and growing genetically modified plants. In this study, pea (Pisum sativum L. accessions were screened for lipid content using a rapid extraction method. This method quantifies lipid concentration in pea seeds and was developed by assessing and comparing the results of existing extraction methods used for canola and soybean, the top two Canadian oilseeds. Seeds of 151 field pea accessions were grown to maturity in 2009 and 2010 at McGill University (Quebec, Canada. Overall, lipid concentration in pea seeds ranged from 0.9 to 5.0%. Among several seed characteristics, only seed shape (wrinkled verses round had a significant effect on the total lipid production in the seeds. Peas are a valuable source of protein and starch, but the lipid concentration in their seeds has been undervalued. This research supports the idea of developing a novel dual-purpose oilseed pea that emulates the protein and oil production in soybean seeds while being conveniently adapted to a colder climate.

    1991-01-01

    Despite a decade of concern about the 'mushrooming' of new hospice developments within the British Isles, we remain remarkably ignorant about the processes which lead to the initiation of new hospice projects and the factors which affect their progress. Three inter-related issues appear important: (1) policy and resource implications; (2) changing models of hospice care; (3) 'community' factors. This paper explores the interconnections between these, using a case study approach and describes in detail the efforts of a single local voluntary group to establish a programme of community care for dying people. It shows that: (1) local 'communities' are likely to make continued demands for hospice type care, despite official scepticism about proliferation; but also that these communities should not be seen as homogeneous in their aspirations and demands; (2) new models of community care will interact with wider policy changes in the NHS and Social Services to raise questions about how terminal care services can be further developed; (3) shifts away from traditional in-patient models of care are likely to high-light divisions between 'lay' and 'professional' groups in their perceptions of how services can be delivered.

    The purpose of this article is to present preliminary results related to the development of a new measure of explicit word learning. The measure incorporated elements of explicit vocabulary instruction and dynamic assessment and was designed to be sensitive to differences in word learning skill and to be feasible for use in clinical settings. The explicit word learning measure included brief teaching trials and repeated fine-grained measurement of semantic knowledge and production of 3 novel words (2 verbs and 1 adjective). Preschool children (N = 23) completed the measure of explicit word learning; standardized, norm-referenced measures of expressive and receptive vocabulary; and an incidental word learning task. The measure of explicit word learning provided meaningful information about word learning. Performance on the explicit measure was related to existing vocabulary knowledge and incidental word learning. Findings from this development study indicate that further examination of the measure of explicit word learning is warranted. The measure may have the potential to identify children who are poor word learners. https://doi.org/10.23641/asha.5170738.

    Full Text Available Cochlear implant surgery is aimed at making a comprehensive packet of information for the deaf by mixing the data acquired by implanted device and the communicational grammar. Although language production and ability of communication are not main factors in determining the candidacy for cochlear implant surgery, they play crucial role in determining cochlear implant success. we should study the communication skills much deeper than a simple perception and production of speech to have a reasonable evaluation of development of Auditory integration and grammatical language structure. Hence in the current article we will first discuss the grammatical structure in language and then have a look at the pragmatics , semantics and phonological aspects in children with cochlear implant in Virginia college in USA.

    2013-04-01

    It is now about 40 years since Avram Goldstein proposed the use of the stereoselectivity of opioid receptors to identify these receptors in neural membranes. In 2012, the crystal structures of the four members of the opioid receptor family were reported, providing a structural basis for understanding of critical features affecting the actions of opiate drugs. This minireview summarizes these recent developments in our understanding of opiate receptors. Receptor function is also influenced by amino acid substitutions in the protein sequence. Among opioid receptor genes, one polymorphism is much more frequent in human populations than the many others that have been found, but the functional significance of this single nucleotide polymorphism (SNP) has been unclear. Recent studies have shed new light on how this SNP might influence opioid receptor function. In this minireview, the functional significance of the most prevalent genetic polymorphism among the opioid receptor genes is also considered.

    Given limitations in the integrative scope of past research, basic questions about the organization and development of preschoolers' living kinds concept remain open to debate. This study was designed to address past limitations through use of a longitudinal design, extensive stimulus set, and alternate indices of understanding. Thirty-five English-speaking 3-year-olds from middle-class families in Albuquerque, NM participated in four testing sessions over 1 year. Indices of understanding included statements that preschoolers generated about various living and nonliving objects, biological properties they attributed to the objects, and their characterization of objects as "alive" or not. Results reveal a multifaceted picture of developmental change in preschoolers' living kinds concept involving both the construction and elaboration of a core biological understanding.

    This review is focused on experimental methods for determination of the composition of the human body, its organs and tissues. It summarizes the development and current status of fat determinations from body density, total body water determinations through the dilution technique, whole and partial body potassium measurements for body cell mass estimates, in vivo neutron activation analysis for body protein measurements, dual-energy absorptiometry (DEXA), computed tomography (CT) and magnetic resonance imaging (MRI, fMRI) and spectroscopy (MRS) for body composition studies on tissue and organ levels, as well as single- and multiple-frequency bioimpedance (BIA) and anthropometry as simple easily available methods. Methods for trace element analysis in vivo are also described. Using this wide range of measurement methods, together with gradually improved body composition models, it is now possible to quantify a number of body components and follow their changes in health and disease.

    This study focuses on the applicability of current accelerator and laser technologies to the construction of compact, narrow bandwidth, gamma-ray sources for DHS missions in illicit materials detection. It also identifies research and development areas in which advancement will directly benefit these light sources. In particular, we review the physics of Compton scattering based light sources and emphasize the source properties most important to Nuclear Resonance Fluorescence (NRF) applications of interest. The influences of laser and electron beam properties on the light source are examined in order to evaluate the utility of different technologies for this application. Applicable bulk and fiber-based laser systems and laser recirculation technologies are discussed and Radio Frequency (RF) Linear Accelerator (linac) technologies are examined to determine the optimal frequency and pulse formats achievable.

    This paper reports part of a study which investigated young children's conceptions of scientific and technological phenomena and the conceptual change that occurs during the teaching of science in pre-school, Transition/Year One and Year Two/Three classrooms. Science lessons from each school/centre were audio and video taped for a period of six months. Informal interviewing of teachers occurred in direct response to lessons observed. Informal interviewing of children was conducted to determine current scientific thinking in relation to the science lessons presented by the teacher. Two main elements emerged. First, different types of teacher-child interactions were evident during the science lessons observed and it was found that specifically focused interactions led to conceptual development in young children. Second, children's views (whether scientific or not) were maintained over a three month period.

    Full Text Available Development of Cooperative Extension programs depends upon the skills and abilities of competent Extension professionals. The most effective manner of building program development competencies in these Extension professionals is through professional development. A wide variety of competencies are necessary for Extension professionals to develop programs, including strong interpersonal skills. Differences exist between the professional development efforts of Extension institutions and are highlighted herein. Major challenges to delivery of professional development include time and budget, but these can be overcome through planning and innovation and use of online or hybrid methods. Professional development for program development is essential to furthering Extension’s mission, especially during times of rapid change.

    Quek, Chwee Geok

    Three cohorts comprising a total of 155 gifted science students who had participated in a research mentorship program, the Science Research Program (SRP) in Singapore, were surveyed in this cross-sectional study. Adapting Gagne's (2003, 2004) Differentiated Model of Giftedness and Talent (DMGT) as a conceptual framework, this study examined the intrapersonal and environmental catalysts that students perceived to have contributed to their talent development in the sciences. It also sought to evaluate the impact of the SRP on the students, and the extent to which it reinforced their passion for the sciences, and decision to pursue careers in science and/or research. Respondents attributed the biggest role to the 'self' in their talent development journey. They perceived that various intrapersonal qualities they had---sense of curiosity, passion for the subject as well as persistence---were most important in nurturing and sustaining their interest and engagement in science. The external catalysts of teachers and the school appeared to have played a bigger role than parents and the home in respondents' perceptions of the influences on their scientific talent development process. Qualitative descriptions of inspiring and memorable teachers were consistent with qualities of effective teachers in the literature. Findings also showed that students felt the SRP had been very effective in enhancing their scientific knowledge and skills, but that it was less impactful in shaping their future course and career decisions. Indeed, except for a handful who reported that the SRP actually helped them discover that science was not really their passion, the majority plan to pursue careers in science, both in research and in applied fields, aspirations they have had since childhood. There appeared to be little attrition of this group from the science pipeline although there are some indications that more might need to be done to attract more gifted females to the field and to help

    An integrated energy database should be prepared in advance for managing energy statistics comprehensively. However, since much manpower and budget is required for developing an integrated energy database, it is difficult to establish a database within a short period of time. Therefore, this study sets the purpose in drawing methods to analyze existing statistical data lists and to consolidate insufficient data as first stage work for the energy database, and at the same time, in analyzing general concepts and the data structure of the database. I also studied the data content and items of energy databases in operation in international energy-related organizations such as IEA, APEC, Japan, and the USA as overseas cases as well as domestic conditions in energy databases, and the hardware operating systems of Japanese databases. I analyzed the making-out system of Korean energy databases, discussed the KEDB system which is representative of total energy databases, and present design concepts for new energy databases. In addition, I present the establishment directions and their contents of future Korean energy databases, data contents that should be collected by supply and demand statistics, and the establishment of data collection organization, etc. by analyzing the Korean energy statistical data and comparing them with the system of OECD/IEA. 26 refs., 15 figs., 11 tabs.

    2015-03-01

    Battelle Energy Alliance (BEA), LLC, has developed processes and equipment for a pilot-scale hot isostatic pressing (HIP) treatability study to stabilize and volume reduce radioactive calcine stored at Idaho National Laboratory (INL). In 2009, the U. S. Department of Energy signed a Record of Decision with the state of Idaho selecting HIP technology as the method to treat 5,800 yd^3 (4,400 m^3) of granular zirconia and alumina calcine produced between 1953 and 1992 as a waste byproduct of spent nuclear fuel reprocessing. Since the 1990s, a variety of radioactive and hazardous waste forms have been remotely treated using HIP within INL hot cells. To execute the remote process at INL, waste is loaded into a stainless-steel or aluminum can, which is evacuated, sealed, and placed into a HIP furnace. The HIP simultaneously heats and pressurizes the waste, reducing its volume and increasing its durability. Two 1 gal cans of calcine waste currently stored in a shielded cask were identified as candidate materials for a treatability study involving the HIP process. Equipment and materials for cask-handling and calcine transfer into INL hot cells, as well as remotely operated equipment for waste can opening, particle sizing, material blending, and HIP can loading have been designed and successfully tested. These results demonstrate BEA’s readiness for treatment of INL calcine.

    2014-11-01

    This article examines the use of action learning sets in a leadership module delivered by a university in south east England. An evaluation research study was undertaking using survey method to evaluate student engagement with action learning sets, and their value, impact and sustainability. Data were collected through a questionnaire with a mix of Likert-style and open-ended questions and qualitative and quantitative data analysis was undertaken. Findings show that engagement in the action learning sets was very high. Action learning sets also had a positive impact on the development of leadership knowledge and skills and are highly valued by participants. It is likely that they would be sustainable as the majority would recommend action learning to colleagues and would consider taking another module that used action learning sets. When compared to existing literature on action learning, this study offers new insights as there is little empirical literature on student engagement with action learning sets and even less on value and sustainability.

    The evolution of nuclear activities and criteria for radiation protection have led to a continuous increase in measures to monitor and control the environment and therefore in the number of determinations required for such purposes. Classical analytical procedures are time-consuming, labor-intense and generate a large amount of waste. The alternative use of sensors for such determinations has seen very limited development. The present study focuses on the evaluation of the behavior of a prototype radiochemical sensor for liquid effluents. The sensor is based on a receptor made of a plastic scintillator and is capable of continuous, on-time and accurate remote quantification of the activity of alpha, beta and beta-gamma emitters. Low-level active solutions of {sup 90}Sr/{sup 90}Y, {sup 238}Pu, {sup 134}Cs and {sup 60}Co in matrices of groundwater, seawater and drinking water were quantified with prediction errors lower than 10% in most cases. The study also yields information about light generation and transmission and transductor configuration that will be useful in the design of future versions of this sensor.

  14. Development of a Molecular System for Studying Microbial Arsenate Respiration

    Saltikov, C. W.; Newman, D. K.

    2002-12-01

    The toxic element arsenic is a major contaminant of many groundwaters and surface waters throughout the world. Arsenic enrichment is primarily of geological origin resulting from weathering processes and geothermal activity. Not surprisingly, microorganisms inhabiting anoxic arsenic-contaminated environments have evolved to exploit arsenate during respiration. Numerous bacteria have been isolated that use arsenate as a terminal electron acceptor for respiratory growth. The diversity of this metabolism appears to be widespread throughout the microbial tree of life, suggesting respiratory arsenate reduction is ancient in origin. Yet little is known about the molecular mechanisms for how these organisms respire arsenate. We have developed a model system in Shewanella trabarsenatis, strain ANA-3, a facultative anaerobe that respires arsenate and tolerates high concentrations of arsenite (10 mM). Through loss-of-function studies, we have identified genes involved in both arsenic resistance and arsenate respiration. The genes that confer resistance to arsenic are homologous to the well-characterized ars operon of E. coli. However, the respiratory arsenate reductase is predicted to encode a novel protein that shares homologous regions (~ 40 % similarity) to molybdopterin anaerobic reductases specific for DMSO, thiosulfate, nitrate, and polysulfide. I will discuss our emerging model for how strain ANA-3 respires arsenate and the relationship between arsenite resistance and arsenate respiration. I will also highlight the relevance of this type of analysis for biogeochemical studies.

    Robots are used to perform jobs where the performer are exposed to the radioactivity. Good human-robot-interface is required to operate the robots easily and smoothly. It is believed that virtual reality and 3D graphics technology will be the beat solution for the good human-robot-interface. Using 3D computer graphics, complex human motions can be captured and displayed on the screen. The captured motion data can be used as the input to= control the remote robots using virtual reality technologies. Thus good human-robot-interface can be constructed. The motion capturing system developed in this study are very convenient and easy to be used to operate the robot. And the required time to operate the robot with the developed system is much shorter than to operate the robots without our motion capturing system. Therefore, efficient usage of the robot and related facilities will prolong the life time of them and reduce the manpower of the operators. The 3D data produced by our system will be used to generate commands to control the robot. 6 refs., 60 figs. (author)

    Southface Energy Institute (Southface) partnered with owners and/or builders with various market constraints and ultimate goals for three projects in different climate zones: Savannah, GA (CZ 2), Clemson, SC (CZ 3), and LaFayette, GA (CZ 4). This report documents the design process, computational energy modeling, construction, envelope performance metrics, long-term monitoring results, and successes and failures of the design and execution of these high performance homes. The three bedroom/two bathroom test home in Savannah Gardens on an elevated slab foundation has a semi-conditioned, encapsulated attic. A neighboring home built to EarthCraft specifications was also monitored as a control for exterior foam insulation and a heat pump water heater (HPWH). For the JMC Patrick Square, a single-story project in Clemson, the small-scale production builder wanted to increase their level of energy efficiency beyond their current green building practices, including bringing ducts into conditioned space. Through a combination of upgrade measures the team met this goal and achieved many Zero Energy Ready Home requirements. LaFayette Housing Authority undertook a development of 30 affordable rental housing units in 15 duplexes in LaFayette, GA. Because they would be long-term owners, their priorities were low utility bills for the residents and durable, maintainable buildings. The team employed BEopt to optimize building envelope and systems choices, including 2x6 advanced framed walls, insulated slab, and heat pump water heater in a utility closet which was ducted to/from an encapsulated attic.

    Full Text Available The tendency to repeat birth weight in successive birth was first published in 1977. The study was based on 81 400 mothers who had their first and second singleton birth within the study period 1967-73, based on information in the Medical Birth Registry of Norway. The paper was presented at a large NICHD (National Center of Child Health and Human Development, NIH seminar focusing on preterm birth. This meeting started a creative, international long lasting collaboration, a series of papers and book chapters has been published. It seemed like mothers are programmed to give birth to babies of a certain size and age. And if they depart from this norm the baby is at an increased risk of mortality. Also, the tendency to repeat gestational age and birth weight exists across generations, with the same increased risk if the pattern is departed from. This means that if a mother who herself was of low birth weight give birth to a likewise small baby, then that baby has improved survival compared to a likewise small baby where the mother was relatively heavy. This effect across generations is also present on the paternal in addition to the maternal side. Recently the medical birth registration data set has provided possibilities to examine the effect of changing partners from one pregnancy to the next one. Also, half siblings (maternal and paternal is another valuable data source to explore. Soon 3 generational repeater studies will become available as the first births in the registry by now become grandmothers and grandfathers.

    Full Text Available Generic drugs are lower-cost versions of patent-expired original brand-name medications. According to guidelines of regulatory agencies of the Canada, US and European Union, a generic drug must be “identical, or bioequivalent to a brand name drug in dosage form, safety, strength, route of administration, quality, performance characteristics and intended use”. Bioequivalence is decreed when the ratio of the generic to the reference compound for the area-under-the-curve and maximum plasma concentration (Cmax fall within a 0.80–1.25 range. The present study was to develop Olanzapine Tablets and compare pharmacokinetic profile of Zyprexa 10 mg film-coated tablets, Zyprexa Velotabs 10 mg orodispersible tablets and Olanzapine 10mg tablets. Multi media dissolution studies in 0.1N HCl, pH 4.5 acetate buffer and pH 6.8 phosphate buffer were carried out for Reference (Zyprexa Velotab 10 mg and Zyprexa 10 mg and test product (i.e. Olanzapine 10 mg. A single centre, open-label, single-dose, randomised, 3-way crossover bioequivalence study, performed under fasting conditions. Based on the results obtained, it can be concluded that the test olanzapine (Treatment A is bioequivalent to both references Zyprexa Velotab (Treatment B and Zyprexa (Treatment C following a 10 mg dose under fasting conditions. All formulations were well tolerated, with no major side effects and no relevant differences in safety profiles were observed between the preparations, particularly with respect to the number and pattern of adverse event.

  20. Radio Astronomers Develop New Technique for Studying Dark Energy

    Science.gov (United States)

    2010-07-01

    Pioneering observations with the National Science Foundation's giant Robert C. Byrd Green Bank Telescope (GBT) have given astronomers a new tool for mapping large cosmic structures. The new tool promises to provide valuable clues about the nature of the mysterious "dark energy" believed to constitute nearly three-fourths of the mass and energy of the Universe. Dark energy is the label scientists have given to what is causing the Universe to expand at an accelerating rate. While the acceleration was discovered in 1998, its cause remains unknown. Physicists have advanced competing theories to explain the acceleration, and believe the best way to test those theories is to precisely measure large-scale cosmic structures. Sound waves in the matter-energy soup of the extremely early Universe are thought to have left detectable imprints on the large-scale distribution of galaxies in the Universe. The researchers developed a way to measure such imprints by observing the radio emission of hydrogen gas. Their technique, called intensity mapping, when applied to greater areas of the Universe, could reveal how such large-scale structure has changed over the last few billion years, giving insight into which theory of dark energy is the most accurate. "Our project mapped hydrogen gas to greater cosmic distances than ever before, and shows that the techniques we developed can be used to map huge volumes of the Universe in three dimensions and to test the competing theories of dark energy," said Tzu-Ching Chang, of the Academia Sinica in Taiwan and the University of Toronto. To get their results, the researchers used the GBT to study a region of sky that previously had been surveyed in detail in visible light by the Keck II telescope in Hawaii. This optical survey used spectroscopy to map the locations of thousands of galaxies in three dimensions. With the GBT, instead of looking for hydrogen gas in these individual, distant galaxies -- a daunting challenge beyond the technical

    Full Text Available The aim of this study was to analyze the specificity and dynamics of psychomotor development in children from triplet pregnancy. The studied group was composed of siblings from triple pregnancy (T1, T2, T3, including two girls and one boy. This longitudinal study comprised three stages: stage I – children aged 25 months, stage II – children aged 29 months, and stage III – children aged 38 months. At each stage, the psychomotor development of children was examined with the Third Edition of Bayley Scales of Infant and Toddler Development (BSID-III and subjectively by their mother. Additionally, medical and nursing documentation was analyzed. Individual psychomotor development of children from triple pregnancy is different with regards to various spheres, and has different rates and dynamics throughout consecutive years. Psychomotor development of children from triple pregnancies is determined by gender and postnatal clinical parameters, i.e. birth weight, head circumference, postnatal morbidity, and prematurity-related conditions.

    Project Objective: The Mississippi Band of Choctaw Indians (MBCI) conducted a study of the feasibility of siting a renewable energy biomass-based installation on tribal lands. The purpose of the study was to determine whether such an installation can be economically sustainable, as well as consistent with the cultural, social, and economic goals of the Tribe. Scope: To achieve the goal of the feasibility study, the following tasks were carried out: (1) Resource availability assessment--The objective of this assessment was to determine the availability of both poultry litter and wood residues for use in the proposed facility. (2) Power utilization assessment--The objective of this assessment was to determine the potential market size for power produced, the existing infrastructure for delivering power to that market, and the costs and economic returns for doing so. (3) Technology review--The objective of this review was to identify one, or more, technical options for detailed economic and technical assessment. The study considered a range of feedstock and product mixtures of poultry litter; wood residues as feedstock; and electrical power and other ancillary products as outputs. Distributed power sources was also examined. Technologies ranging from gasification to systems that produce both power and value-added chemicals were considered. Technologies selected for detailed review were those that can be sized to process the amount of available feed (poultry litter, or poultry litter and wood residues), and that also appear to make economic sense in terms of the value of their inputs. The technology review leaned heavily on the experience from similar prior DOE projects, particularly those conducted by the National Renewable Energy Laboratory (NREL). NREL was involved in a consultative role, so that the project team could leverage their experience. (4) Systems Design(s)--Based on the technology review, a pre-conceptual design for an installation was developed. This

    2010-05-01

    Vibrational spectroscopic techniques such as near-infrared (NIR), Fourier transform infrared (FTIR), and Raman spectroscopy are valuable diagnostic tools that can be used to elucidate comprehensive structural information of numerous biological samples. In this review article, we have highlighted the advantages of nanotechnology and biophotonics in conjunction with vibrational spectroscopic techniques in order to understand the various aspects of new kind of synthetic biopolymers termed as polyethylene glycol (PEG)ylated lipids. In contrast to conventional phospholipids, these novel lipids spontaneously form liposomes or nanovesicles upon hydration, without the supply of external activation energy. The amphiphiles considered in this study differ in their hydrophobic acyl chain length and contain different units of PEG hydrophilic headgroups. We have further explored the thermotropic phase behaviors and associated changes in the conformational order/disorder of such lipids by using variable-temperature FTIR and Raman spectroscopy. Phase transition temperature profiles and correlation between various spectral indicators have been identified by either monitoring the shifts in the vibrational peak positions or plotting vibrational peak intensity ratios in the C--H stretching region as a function of temperature. To supplement our observations of phase transformations, a thermodynamic approach known as differential scanning calorimetry (DSC) has been applied and revealed a good agreement with the infrared and Raman spectroscopic data. Finally, the investigation of thermal properties of lipids is extremely crucial for numerous purposes, thus the results obtained in this work may find application in a wide variety of studies including the development of PEGylated lipid based drug and substances delivery vehicles.

  11. Developing Carbon Budgets for Cities: Phoenix as a Case Study

    McHale, M. R.; Baker, L. A.; Koerner, B. A.; Grimm, N. B.

    2008-12-01

    Studies have shown that cities can alter regional carbon dynamics through changing ecosystem productivity, overall carbon cycling rate, and total carbon storage in vegetation and soils. Furthermore, people in urban regions import a large amount of carbon in food and fuel, as well as release an exceptional amount of CO2 into the atmosphere. Numerous studies have attempted to quantify some sources and sinks of carbon in urban areas, although a complete carbon budget for a city that accounts for total inputs, outputs, and storage within the ecosystem has yet to be fully accomplished. One challenge is associated with attaining the data necessary to accurately account for all carbon dynamics in these heterogeneous and complex ecosystems. Our goal was to estimate a budget for the Phoenix metropolitan area while developing methodology to calculate carbon dynamics in urban systems that can be applied to cities across the US. Only with comparable carbon budgets for multiple cities will we finally begin to understand the influence of urbanization on carbon dynamics. Our analysis shows when calculating certain variables like transportation emissions, results can vary radically (up to 250%) depending on the data source and methodology implemented (i.e. bottom-up vs. top-down). A common assumption is that productivity and carbon storage will increase with urbanization in arid systems due to water and nutrient inputs, as well as changes in vegetation structure; however, our results indicated that this may not actually be the case in Phoenix where a large number of residents design landscapes to conserve water. Even if all urban expansion was dedicated to landscapes designed for carbon sequestration and storage, vegetation and soils will unlikely have a large effect on the C budget without significant changes in transportation and lifestyle choices.

The study population consists of the students attending the 23 universities which has Music Education Department. The sample of the study consists of 438 girls and 312 boys, totally 750 students  who are studying in the Department of Music Education of randomly selected 10 universities. As a result of the explanatory and confirmatory factor analyses that were performed, a one-dimensional structure consisting of 14 items was obtained. Also, t-scores and  the coefficient scores of total item correlation concerning the distinguishing power of the items, the difference in the scores of the set of lower and upper 27% was calculated, and it was observed that the items are distinguishing as a result of both analyses. Of the scale, Cronbach's alpha coefficient of internal consistency was calculated as .94, and test-retest reliability coefficient was calculated as .93. As a result, a valid and reliable assessment and evaluation instrument that measures the exam performance anxiety of the students studying in the Department of Music Education, has been developed.Extended AbstractsIntroductionAnxiety is a universal phenomenon which people experience once or a few times during lives. It was accepted as concern for the future or as an unpleasant emotional experience regarding probable hitches of the events (Di Tomasso & Gosch, 2002.In general, the occasions on which negative feelings are experienced cause anxiety to arise (Baltaş and Baltaş, 2000. People also feel anxious in dangerous situations. Anxiety may lead a person to be creative, while it may have hindering characteristics. Anxiety is that an individual considers him

    Given worldwide concern about a decline in student engagement in school science and an increasing call for science for citizenship in New Zealand Curriculum, this study focused on a butterfly unit that investigated how students in a year-4 primary classroom learnt about New Zealand butterflies through thinking, talking, and acting as citizen scientists. The butterfly unit included five lessons. The researchers observed the lessons and interviewed students and the classroom teacher. The students completed a unit evaluation survey after the unit. Findings indicate that the students enjoyed and were interested in activities such as reading about butterflies, learning and using new vocabulary, drawing butterfly life cycles, as well as hunting, tagging and releasing butterflies and publishing the data they had collected on a dedicated website. Through their participation in the unit, students had opportunities to act locally and globally, and to `see themselves' in science through `being there' experience. Units like this have the potential to develop students' interest for longer-term engagement in science, even those students who may never envision themselves as professional scientists.

    . The NWMO designed its process to be transparent and inclusive of a broad diversity of voices. In so doing the NWMO set out to ensure that a broad range of social and ethical considerations were raised and factored into decision-making at key decision-points in the study. The NWMO developed the Adaptive Phased Management approach as, its preferred approach, in response to the direction it heard from the dialogue process. Adaptive Phased Management consists of both a technical method and a management system. The key attributes of the approach include: Ultimate centralized containment and isolation of used nuclear fuel in an appropriate geological formation; Phased and adaptive decision-making, with explicit decision points to incorporate new social learning and technological innovation; Optional shallow storage at the central site as a contingency; Continuous monitoring; Provision for retrievability; Citizen engagement throughout all phases of implementation; and A future society will decide whether and when to seal and backfill the repository. The NWMO believes that the evidence of common ground that has emerged from the dialogue provides the foundation for the Adaptive Phased Management approach to be taken. Adaptive Phased Management tries to find an optimal balance of what are at times competing societal objectives. It is responsible, in that it brings to bear the knowledge, expertise and wisdom of a wide variety of specialist communities to help understand the options. It is also responsive to what we understand to be the values and expectations of Canadians in providing safe and secure isolation of used nuclear fuel for the very long term. The NWMO delivered its recommendation to the Government of Canada in November, 2005. Once the Government decides upon a long-term management approach for Canada, the NWMO will become the implementing organization.

    2016-12-01

    Our objective was to replicate previous cross-linguistic findings by comparing Portuguese and U.S. children with respect to (a) effects of language, gender, and age on vocabulary size; (b) lexical composition; and (c) late talking. We used the Language Development Survey (LDS; Rescorla, 1989) with children (18-35 months) learning European Portuguese (n = 181) and English (n = 206). In both languages, girls had higher vocabulary scores than boys and vocabulary scores increased with age. Portuguese LDS scores were significantly lower than English scores, but the effect size was small. Cross-linguistic concordance of percentage use scores yielded a Q correlation of .50, with 64 of the "top 100" words being exact matches. Cross-linguistic concordance was highest for the youngest age group. In both languages, vocabulary composition in late talkers (children ≥ 24 months with < 50 words) was highly correlated with composition in vocabulary size-matched younger children. Results replicated previous Greek, Korean, and Italian LDS studies. The early lexicons of typical talkers and late talkers contained many of the same words, indicating considerable universality and suggesting good targets for clinical intervention.

    Full Text Available One of the most important strategic aims of Serbian economic development is supporting of the villages sustainable development through rural economy diversification where rural tourism development has an important place. In spite of this model of tourism importance recognition as a possible way of rural areas development, Serbia is in an opening phase of. Although there are several positive examples, it is significant that recent projects haven't been established according to national and European development programs, but according to private initiatives of individuals and groups. Rural tourism is an important component of integrated and sustainable development and revitalization of villages, as well an an important factor in encouraging the development of local agricultural and non-farmer activities in rural areas and villages, and also a special incentive to employment. This work highlights the importance of rural tourism in the function of the revitalization of the village, focusing on the challenges of the environment and the possible directions of development in the context of creating a recognizable tourist product and brand of rural tourism in Vojvodina.

  11. Experimental developments for the study of explosive nucleosynthesis in stars

    Science.gov (United States)

    Erikson, Luke

    For several years now, the n-SNS collaboration has been working to place a small neutrino detector at the Spallation Neutron Source at Oak Ridge National Lab. If successful, the experiment may produce the needed neutrino-nucleus cross sections on solid targets such as iron and aluminum. These reaction probabilities are of great interest for a number of reasons, including: neutrino astronomy, explosive nucleosynthesis, and nuclear structure. However, success for this project requires a very efficient cosmic ray detector to exclude backgrounds. The system would need to be ~99% efficient while remaining affordable in a difficult financial climate for basic science. The first half of this thesis addresses a prototype cosmic ray veto based on extruded scintillator with embedded wave-length-shifting fibers. This approach has been successfully used before, and may provide the performance needed for this project. However, our results suggest some additional research and development would be required to meet the requirements for the n-SNS experiment. The second half of this thesis relates to experimental work to study the resonance strength of the 23 Mg(p,g) 24 Al reaction. For this purpose a radioactive ion beam experiment has been conducted at TRIUMF using the DRAGON experiment. This reaction is thought to play an important role during explosive nucleosynthesis such as novae and X-ray bursts. If so, then accurate knowledge of this break-out reaction would help explain the isotopic abundances around that mass range in the universe. Our results suggest the rate of this reaction at astrophysically relevant energies is lower than predicted and might further exclude explosive binary systems as the production site for such elements as 26 Al.

    The Child Development Supplement (CDS) was started in 1997 to collect information on children and caregivers in families in the USA that participated in the Panel Study of Income Dynamics (PSID), an ongoing national longitudinal household survey that began in 1968. CDS was launched with the goal of creating a comprehensive, nationally representative, prospective database of young children and their families for studying the dynamic process of children's health and development. The same children and their caregivers were interviewed in up to three waves approximately every 5 years (1997, 2002-03, and 2007-08), with a child-based response rate of 90% in the most recent wave. Upon reaching age 18 years and finishing or leaving high school, the children in the CDS cohort shifted to a six-wave follow-up study launched in 2005 called the PSID Transition into Adulthood (TA) study. The TA data have been collected biennially through 2013, with a final wave planned for 2015. Once these young adults form their own economically independent households, they join the PSID. The main categories of data emphasize the major developmental tasks of childhood and young adulthood, including influences on successful development in the domains of family, schools and neighbourhoods. The majority of data and documentation are freely and publicly available through the PSID Online Data Center.

    Since urban population is growing fast and urban areas are recognized as the major source of CO2 emissions, more attention has being dedicated to the topic of urban sustainability and its connection with the climate. Urban flows of energy, water and carbon have an important impact on climate change and their quantification is pivotal in the city design and management. Large effort has been devoted to quantitative estimates of the urban metabolism components, and several advanced models have been developed and used at different spatial and temporal scales for this purpose. However, it is necessary to develop suitable tools and indicators to effectively support urban planning and management with the goal of achieving a more sustainable metabolism in the urban environment. In this study, the multilayer model ACASA (Advanced Canopy-Atmosphere-Soil Algorithm) was chosen to simulate the exchanges of heat, water vapour and CO2 within and above urban canopy. After several calibration and evaluation tests over natural and agricultural ecosystems, the model was recently modified for application in urban and peri-urban areas. New equations to account for the anthropogenic contribution to heat exchange and carbon production, as well as key parameterizations of leaf-facet scale interactions to separate both biogenic and anthropogenic flux sources and sinks, were added to test changes in land use or urban planning strategies. The analysis was based on the evaluation of the ACASA model performance in estimating urban metabolism components at local scale. Simulated sensible heat, latent heat, and carbon fluxes were compared with in situ Eddy Covariance measurements collected in the city centre of Florence (Italy). Statistical analysis was performed to test the model accuracy and reliability. Model sensitivity to soil types and increased population density values was conducted to investigate the potential use of ACASA for evaluating the impact of planning alternative scenarios. In

    2017-08-01

    Smartphone apps have emerged as valuable research tools to sample human behaviours at their time of occurrence within natural environments. Human behaviour sampling methods, such as Ecological Momentary Assessment (EMA), aim to facilitate research that is situated in ecologically valid real world environments rather than laboratory environments. Researchers have trialled a range of EMA smartphone apps to sample human behaviours such as dieting, physical activity and smoking. Software development processes for EMA smartphones apps, however, are not widely documented with little guidance provided for the integration of complex multidisciplinary behavioural and technical fields. In this paper, the AlcoRisk app for studying alcohol consumption and risk taking tendencies is presented alongside a software development process that integrates these multidisciplinary fields. The software development process consists of three stages including requirements analysis, feature and interface design followed by app implementation. Results from a preliminary feasibility study support the efficacy of the AlcoRisk app's software development process. Copyright © 2017 Elsevier Inc. All rights reserved.

    Geotourism and Geoparks in particular are real opportunities to rural developments promoting the rate decline of unemployment and emigration through engaging the local communities in geopark activities and tourism marketing in the form of adventure tourism, ecotourism, rural tourism and health geotourism. Geotourism is closely linked with Medical Geology. The intake of minerals and chemical elements for food, water, soil (through geophagy) or dust can be accomplished by ingestion, inhalation or dermal absorption. Pelotherapy or “Mudtherapy” is the use of mud/clay for therapeutic applications, internal or external. Cape Verde archipelago is located in Atlantic ocean, 400 km westwards of Senegal coast. Geotourism is being developed, mainly focused on the development of a geopark in Fogo island huge caldera, but also trying to take advantage of their potentialities for Geomedecine. A cooperative program established between Cape Verde University (UCV) and Aveiro University (UA, Portugal) is under way, aiming, on a first stage, to identify Geotouristic potentialities and, on a second stage, to develop products.

This study aimed to develop a new internal fixator absorbable scaphoid screw (ASS for fixation of the scaphoid waist after fracture and to test the biomechanical characteristics of ASS.Materials and methods: An ASS was prepared using polylactic acids and designed based on scaphoid measurements and anatomic features. Twenty fractured scaphoid waist specimens were randomly divided into experimental and control groups (n=10/group. Reduction and internal fixation of the scaphoid were achieved with either Kirschner wires (K-wires or ASS. A moving target simulator was used to test palmar flexion and dorsal extension, with the range of testing (waist movement set from 5° of palmar flexion to 25° of dorsal extension. Flexion and extension were repeated 2,000 times for each specimen. Fracture gap displacements were measured with a computerized tomography scanning. Scaphoid tensile and bending strengths were measured by using a hydraulic pressure biomechanical system.Results: Prior to biomechanical fatigue testing, fracture gap displacements were 0.16±0.02 mm and 0.22±0.02 mm in the ASS and K-wire groups, respectively. After fatigue testing, fracture gap displacements in the ASS and the K-wire groups were 0.21±0.03 mm and 1.52±0.07 mm, respectively. The tensile strengths for the ASS and K-wire groups were 0.95±0.02 MPa and 0.63±0.02 MPa, respectively.Conclusion: Fixation using an ASS provided sufficient mechanical support for the scaphoid after fracture.

    2008-01-01

    Indian healthcare is in the process of offering a plethora of services to customers hailing largely from India and from neighboring countries. The Indian hospital sector consists of private "nursing homes" and government and charitable missionary hospitals. Government and missionary hospitals determine their charges according to patients' income levels and treat poor patients freely. Nursing homes charged higher, market-determined rates. They offer services in just a few medical specialties, owned and operated by physicians who worked with them. Nursing homes cannot afford the latest medical technology, but they provide more intimate settings than government hospitals. This case study aims to demonstrate the various strategic options available to a for-profit hospital, in an emerging economy with a burgeoning middle-class population and how it can choose which services that it can best offer to its target population. Diagnosing and treating complex ailments in nursing homes could be a time-consuming and expensive proposition as visits to several nursing homes with different specialties may be necessary. This paper demonstrates how an hospital can develop new customer-oriented services and eliminate the hassle for patients needing to run around different healthcare outlets even for minor ailments. The paper finds that large government hospitals generally have better facilities than nursing homes, but they were widely believed to provide poor-quality care. They failed to keep up with advanced equipment, train their technicians adequately and did not publicize their capabilities to doctors who might refer patients. Many missionary and charitable hospitals were undercapitalized and did not offer all services. These conditions left an unsatisfied demand for high-quality medical care. In 1983, LIFENET opened in Madras, becoming the first comprehensive, for-profit hospital in India. LIFENET, invested in a cardiology laboratory and clinics with capacity to diagnose heart

  17. Coal resources available for development; a methodology and pilot study

    1990-01-01

    Coal accounts for a major portion of our Nation's energy supply in projections for the future. A demonstrated reserve base of more than 475 billion short tons, as the Department of Energy currently estimates, indicates that, on the basis of today's rate of consumption, the United States has enough coal to meet projected energy needs for almost 200 years. However, the traditional procedures used for estimating the demonstrated reserve base do not account for many environmental and technological restrictions placed on coal mining. A new methodology has been developed to determine the quantity of coal that might actually be available for mining under current and foreseeable conditions. This methodology is unique in its approach, because it applies restrictions to the coal resource before it is mined. Previous methodologies incorporated restrictions into the recovery factor (a percentage), which was then globally applied to the reserve (minable coal) tonnage to derive a recoverable coal tonnage. None of the previous methodologies define the restrictions and their area and amount of impact specifically. Because these restrictions and their impacts are defined in this new methodology, it is possible to achieve more accurate and specific assessments of available resources. This methodology has been tested in a cooperative project between the U.S. Geological Survey and the Kentucky Geological Survey on the Matewan 7.5-minute quadrangle in eastern Kentucky. Pertinent geologic, mining, land-use, and technological data were collected, assimilated, and plotted. The National Coal Resources Data System was used as the repository for data, and its geographic information system software was applied to these data to eliminate restricted coal and quantify that which is available for mining. This methodology does not consider recovery factors or the economic factors that would be considered by a company before mining. Results of the pilot study indicate that, of the estimated

  18. A forecasting study on Chinese television development (1986 to 2001).

    Given its widespread availability and impact on social values, television is expected to play an important role in China's modernization drive. Necessary to this process is a detailed analysis of the framework in which the technical aspects of television's development are related to political, economic, telecommunications, and social factors. To facilitate this analysis, a Delphi survey was conducted in 1986 as was a cross-impact analysis assisted by computer modelling. Entitled "Future Development of Chinese Television, 1986-2001," the Delphi survey sought to provide decision makers with operationally meaningful assistance in the form of information and analysis. The responses from experts suggested that, if economic growth can be sustained over the next 5 years, telecommunications development will receive top priority in state planning. Cross-impact analysis helps to clarify and promote better understanding of the complex relationships among future events and trends. This analysis tended to confirm the hypothesis that a nongovernmental television station is unlikely to emerge before 1991. Crucial to the success of any television policy (such as cable television service or videotext systems) is legislative support. The appearance of a nongovernmental television station would have a considerable impact on the private sector in China and lead to competition in programming quality, attracting audiences, and further commercialization. While the future development of Chinese television is dependent on economic factors such as purchasing power and the quality of life, its development can thus also be expected to exert a strong influence on economic life.

    Full Text Available Rural tourism and agricultural tourism are activities, which generate alternative incomes, a fact that offers development possibilities to the rural space, due to the unique landscapes, large semi-natural areas, the inhabitants' born hospitality in the rural surroundings. From this perspective, a modernization, development and innovation process for the Romanian rural tourism is required. All these aspects, however, require financing. Therefore, a pre-accession financing source of the rural tourism was the SAPARD programme, a programme which "offered the opportunity" to many business people to start their business in this field. The paper shows the evolution of the rural boarding houses between 2003-2007, with analyses on the number, type of financing, development region.

    Aurelia polyps (scyphistomae) and ephyrae were exposed to microgravity for nine days aboard the space shuttle during the SLS-1 mission. During strobilation, polyps segment transversely and each segment develops into an ephyra. Polyps were induced to strobilate at 28°C, using iodine or thyroxine, at L(Launch)-48h, L-24h, and L+8h. Ephyrae developed in the groups tested in space and on Earth. The number of ephyrae formed per polyp was slightly higher in the L+8h groups as compared with those induced at L-24h and L-48h. On Earth, iodine is used by jellyfish to synthesize jellyfish-thyroxine (JfT 4), needed for ephyra production. Since iodine-treated polyps strobilated and formed ephyrae in space, it appears that jellyfish can synthesize Jf-T4 in space. Indeed, two groups of polyps not given inducer formed ephryae in space, presumably due to enhanced Jf-T4 synthesis, utilization or accumulation. Some ephyrae that formed in space were also fixed in space on Mission Day (MD) 8; others were fixed post-flight. Examination of living ephyrae with the light microscope and fixed ones with the Scanning and Transmission Electron Microscopes revealed that those which developed in space were morphologically very similar to those which developed on Earth. Quantitation of arm numbers determined that there were no significant differences between space and Earth-developed ephyrae. Pulsing abnormalities, however, were found in greater numbers (18.3%) in space-developed ephyrae than in Earth-developed controls (2.9%). These abnormalities suggest abnormal development of the graviceptors, the neuromuscular system, or a defect in the integration between these systems in apparently microgravity-sensitive animals.

    Full Text Available Context: Globalization has affected all productive sectors and in particular the software industry, which has required the development of new methodologies to suit the speed of the changes and allow quickly build products that meet the requirements of the customers. On the other hand, the GPS technology, 4G connectivity and integration of social networks that have the most current mobile phones have opened a large field of application, particularly in the area of the transport, mobility and citizen complaint, whose development can be successfully addressed through an agile methodology. Method: Agile methodology Scrum was used for the development of a mobile application on the Android operating system and GPS technology, which allows a Bogota taxi user to monitor the route and send a complaint to the social network Twitter in case of nonconformity. Some UML models were used for analysis and design of the application, and a confidence interval was used to validate the results. Results: Prototype of a mobile taximeter developed with an agile methodology that meets quality characteristics, extensibility and maintainability. T-student distribution was used to validate the measurement of the prototype on 50 samples, concluding that the difference between the measurement of a real taximeter and our mobile taximeter is on average 2 units with a standard deviation of 1,39 units. Conclusions: It is shown that with the agile development can be combined with UML modeling tools and statistical validation techniques for quality products that do not violate, but on the contrary, that reaffirm the agile development principles.

    1998-10-01

    To evaluate the normal development of functional hand motor skill, the kinematics of prehension movements were analyzed in 54 healthy children (age 4-12 years). The subjects repeatedly reached out for cylindrical target objects and grasped them with a precision grip of their dominant hand. The trajectory of the reaching hand and the finger aperture were monitored by optoelectronic motion analysis. To obtain comparable conditions for the different age groups, the experimental setup was scaled according to the individual body proportions of each subject. Within the investigated age range, neither the movement duration nor the normalized (according to body proportions) peak spatial velocity of the reaching hand changed significantly. However, the hand trajectory straightened and the coordination between hand transport and grip formation improved, resulting in smooth and stereotyped kinematic profiles at the age of 12 years. The younger children opened their grip relatively wider than the older ones, thus grasping with a higher safety margin. The dependence on visual control of the movement declined during motor development. Only the oldest children were able to scale the grip aperture adequately, according to various sizes of the target objects, when visual control of the movement was lacking. The results suggest that the development of prehensile skills during childhood lasts until the end of the first decade of life. This functional maturation is discussed in relation to the development of neuronal pathways.

  11. Language Development in Context: A Longitudinal Study of Typically-Developing Children and Children with ASD

    DEFF Research Database (Denmark)

    Fusaroli, Riccardo; Weed, Ethan; Fein, Deborah

    Background: Children with Autism Spectrum Disorder (ASD) often display distinctive language development trajectories (Tek et al., 2013). Because language-learning is a social endeavor, these trajectories could be partially grounded in the dynamics that characterize the children's social...... and linguistic interactions (Waurlamont et al., 2014). Objectives: We investigate language development trajectories and interpersonal linguistic adaptation over time in a longitudinal corpus of parent-child interactions. Methods: Participants included 66 children, 33 with ASD (MA=33 months at visit 1) and 33 TD...... in children with ASD and their parents. Our results suggest that a quantifiable feedback loop between parents and children does exist in language development, and that this feedback loop is affected by the severity of autistic traits. This mutual adaptation mechanism appears to be in place in interactions...

  14. Engineering development of selective agglomeration: Trace element removal study

    Energy Technology Data Exchange (ETDEWEB)

    1993-09-01

    Southern Company Services, Inc., (SCS) was contracted in 1989 by the US Department of Energy (DOE) to develop a commercially acceptable selective agglomeration technology to enhance the use of high-sulfur coals by 1993. The project scope involved development of a bench-scale process and components, as well as the design, testing, and evaluation of a proof-of-concept (POC) facility. To that end, a two-ton-per-hour facility was constructed and tested near Wilsonville, Alabama. Although it was not the primary focus of the test program, SCS also measured the ability of selective agglomeration to remove trace elements from coal. This document describes the results of that program.

    Agustí, N; de Vicente, M C; Gabarra, R

    2000-06-01

    DNA markers of Trialeurodes vaporariorum were developed to detect remains of these whitefly in the gut of the predator Dicyphus tamaninii. A 2400-bp DNA fragment of T. vaporariorum, absent in other closely related prey species and in the predator banding pattern, was identified by random amplified polymorphic DNA (RAPD) analysis. After cloning and sequencing this fragment, two pairs of sequence-characterized amplified region (SCAR) primers were developed, amplifying single bands of 2100 bp and 310 bp, respectively. Detection of T. vaporariorum DNA in the predator gut was only possible using the primers that amplified the shortest fragment. Specificity tests performed with this pair of primers showed the presence of the 310-bp band for T. vaporariorum in all stages.

    2005-03-01

    Full Text Available Abstract Background Cluster headache (CH is a neurovascular, primary headache disorder. There are, however, several case reports about patients whose CH started shortly after a structural brain disease or trauma. Motivated by a patient who developed CH 3 weeks after the removal of an eye and by similar case reports, we tested the hypothesis that the removal of an eye is a risk factor for CH. Methods A detailed headache questionnaire was filled out by 112 patients on average 8 years after enucleation or evisceration of an eye. Results While 21 % of these patients experienced previously unknown headaches after the removal of an eye, no patient fulfilled the diagnostic criteria for CH. Conclusion Our data does not suggest that the removal of an eye is a major risk factor for the development of CH.

  17. A Case Study of Coordination in Distributed Agile Software Development

    Science.gov (United States)

    Hole, Steinar; Moe, Nils Brede

    Global Software Development (GSD) has gained significant popularity as an emerging paradigm. Companies also show interest in applying agile approaches in distributed development to combine the advantages of both approaches. However, in their most radical forms, agile and GSD can be placed in each end of a plan-based/agile spectrum because of how work is coordinated. We describe how three GSD projects applying agile methods coordinate their work. We found that trust is needed to reduce the need of standardization and direct supervision when coordinating work in a GSD project, and that electronic chatting supports mutual adjustment. Further, co-location and modularization mitigates communication problems, enables agility in at least part of a GSD project, and renders the implementation of Scrum of Scrums possible.

  18. Sustaining urban development through participation: an Ethiopian case study.

    Science.gov (United States)

    Tadele, F

    1996-02-01

    Under the Mengistu regime, Addis Ababa was divided into six zones, 28 woredas, and 303 kebeles, the kebeles being the smallest grassroots administrative unit. To enhance community participation, the Kebele 29 Project promoted the establishment of grassroots community groups by dividing the kebele into four zones and 37 neighborhoods. Each neighborhood is represented by a chairperson and a deputy who take responsibility for reviewing the priority needs of households, relaying information between the project and the community, and following up the project interventions. The author considers the sustainability of income-generating activities established as part of many urban development projects instigated by development agencies, the likelihood of inhabitants generating enough income for the upkeep of new or improved infrastructure, and whether the necessary commitment from the community can be created in a situation in which civil organizations have been banned or discouraged. These issues are considered in the context of Oxfam UK/I's involvement in the Kebele 29 Project.

  1. Development of the perceptual span in reading: A longitudinal study.

    Science.gov (United States)

    Sperlich, Anja; Meixner, Johannes; Laubrock, Jochen

    2016-06-01

    The perceptual span is a standard measure of parafoveal processing, which is considered highly important for efficient reading. Is the perceptual span a stable indicator of reading performance? What drives its development? Do initially slower and faster readers converge or diverge over development? Here we present the first longitudinal data on the development of the perceptual span in elementary school children. Using the moving window technique, eye movements of 127 German children in three age groups (Grades 1, 2, and 3 in Year 1) were recorded at two time points (T1 and T2) 1 year apart. Introducing a new measure of the perceptual span, nonlinear mixed-effects modeling was used to separate window size effects from asymptotic reading performance. Cross-sectional differences were well replicated longitudinally. Asymptotic reading rate increased monotonously with grade, but in a decelerating fashion. A significant change in the perceptual span was observed only between Grades 2 and 3. Together with results from a cross-lagged panel model, this suggests that the perceptual span increases as a consequence of relatively well-established word reading. Stabilities of observed and predicted reading rates were high after Grade 1, whereas the perceptual span was only moderately stable for all grades. Comparing faster and slower readers as assessed at T1, in general, a pattern of stable between-group differences emerged rather than a compensatory pattern; second and third graders even showed a Matthew effect in reading rate and the perceptual span, respectively.

    2008-04-15

    The Department of Energy (DOE), National Energy Technology Center (NETL), has initiated a strategic plan for the development of advanced technologies needed to design and build fossil fuel plants with very high efficiency and environmental performance. These plants, referred to as 'Vision 21' and FutureGen programs by DOE, will produce electricity, chemicals, fuels, or a combination of these products, and possibly secondary products such as steam/heat for industrial use. MA956 is a prime candidate material being considered for a high temperature heat exchanger in the 'Vision 21' and FutureGen programs. This material is an oxide dispersion strengthened (ODS) alloy; however, there are some gaps in the data required to commit to the use of these alloys in a full-size plant. To fill the technology gaps for commercial production and use of the material for 'Advanced Power Generation Systems' this project has performed development activity to significant increase in circumferential strength of MA956 as compared to currently available material, investigated bonding technologies for bonding tube-to-tube joints through joining development, and performed tensile, creep and fire-side corrosion tests to validate the use and fabrication processes of MA956 to heat exchanger tubing applications. Development activities within this projected has demonstrated increased circumferential strength of MA956 tubes through flow form processing. Of the six fabrication technologies for bonding tube-to-tube joints, inertia friction welding (IFW) and flash butt welding (FBW) were identified as processes for joining MA956 tubes. Tensile, creep, and fire-side corrosion test data were generated for both base metal and weld joints. The data can be used for design of future systems employing MA956. Based upon the positive development activities, two test probes were designed and fabricated for field exposure testing at 1204 C ({approx}2200 F) flue gas. The probes

    2010-02-03

    The South Carolina Bio-Energy Research Collaborative is working together on the development and demonstration of technology options for the production of bio-fuels using renewable non-food crops and biomass resources that are available or could be made available in abundance in the southeastern United States. This collaboration consists of Arborgen LLC, Clemson University, Savannah River National Laboratory, and South Carolina State University, with support from Dyadic, Fagen Engineering, Renewed World Energies, and Spinx. Thus far, most work has centered on development of a fermentation-based process to convert switchgrass into ethanol, with the concomitant generation of a purified lignin stream. The process is not feed-specific, and the work scope has recently expanded to include sweet sorghum and wood. In parallel, the Collaborative is also working on developing an economical path to produce oils and fuels from algae. The Collaborative envisions an integrated bio-fuels process that can accept multiple feedstocks, shares common equipment, and that produces multiple product streams. The Collaborative is not the only group working on bio-energy in South Carolina, and other companies are involved in producing biomass derived energy products at an industrial scale.

    In recent years, cyberinfrastructures have been deployed to create virtual research environments (VREs) - such as the Virtual Astronomical Observatory (VAO) - to enhance the quality and speed of scientific research, and to foster global scientific communities. Our study utilizes process methodology to study the evolution of VREs. This approach focuses on a series of events that bring about or lead to some outcome, and attempts to specify the generative mechanism that could produce the event series. This paper briefly outlines our approach and describes initial results of a case study of the VAO, one of the participating VREs. The case study is based on interviews with seven individuals participating in the VAO, and analysis of project documents and online resources. These sources are hand tagged to identify events related to the thematic tracks, to yield a narrative of the project. Results demonstrate the event series of an organization through traditional methods augmented by virtual sources.

    1995-10-01

    Many DOE waste streams and remediates contain complex and variable mixtures of organic compounds, toxic metals, and radionuclides. These materials are often dispersed in organic or inorganic matrices, such as personal protective equipment, various sludges, soils, and water. Incineration and similar combustive processes do not appear to be viable options for treatment of these waste streams due to various considerations. The objective of this project is to develop a novel catalytic wet oxidation process for the treatment of multi-component wastes. The DETOX process uses a unique combination of metal catalysts to increase the rate of oxidation of organic materials.

    Cartilage tissue engineering has primarily focused on the generation of grafts to repair cartilage defects due to traumatic injury and disease. However engineered cartilage tissues have also a strong scientific value as advanced 3D culture models. Here we first describe key aspects of embryonic chondrogenesis and possible cell sources/culture systems for in vitro cartilage generation. We then review how a tissue engineering approach has been and could be further exploited to investigate different aspects of cartilage development and degeneration. The generated knowledge is expected to inform new cartilage regeneration strategies, beyond a classical tissue engineering paradigm.

    In this paper, we reported the results of our efforts in developing DCPA/nanosilica composite orthopedic cement. It is motivated by the significances of DCPA and silicon in bone physiological activities. More specifically, this paper examined the effects of various experimental parameters on the properties of such composite cements. In this work, DCPA cement powders were synthesized using a microwave synthesis technique. Mixing colloidal nanosilica directly with synthesized DCPA cement powders can significantly reduce the washout resistance of DCPA cement. In contrast, a DCPA-nanosilica cement powder prepared by reacting Ca(OH)2 , H3 PO4 and nanosilica together showed good washout resistance. The incorporation of nanosilica in DCPA can improve compressive strength, accelerate cement solidification, and intensify surface bioactivity. In addition, it was observed that by controlling the content of NaHCO3 during cement preparation, the resulting composite cement properties could be modified. Allowing for the development of different setting times, mechanical performance and crystal features. It is suggested that DCPA-nanosilica composite cement can be a potential candidate for bone healing applications.

    2016-01-01

    Full Text Available This paper tests the hypothesis that institutional capabilities have a positive effect on economic development. Methodologically, we used descriptive and multivariate statistics, spatial analysis and Ordinary Least Squares (OLS linear regression to estimate their effect. Spatial correlation was tested between the countries by their respective capabilities indexes. The results show in an aggregated level that institutional capabilities do have a positive effect on economic development. However, when we disaggregated by geographic region, we realized that this relation is significant only in four of them: (1 East Asia and Pacific, (2 Europe and Central Asia, (3 Latin America and Caribbean and (4 Middle East and North Africa. For OECD countries, the institutional capability effect is larger for members than for non-members. Taking political regime in consideration, our index performs better in democracies. In the end, global spatial autocorrelation indicates a weak, positive and statistically significate association comparing with institutional capability. (I = 0,192; p-value<0.05.

    Heart disease disproportionately affects Native Hawaiians and other Pacific people. In response, researchers proposed and communities endorsed, developing a cardiac rehabilitation (CR) program based on the hula, a Native Hawaiian dance form. The utilization of cultural practices in health interventions can improve outcomes and increase enrollment and retention, but requires sensitivity and understanding. This paper provides the conceptual framework and methods used for integration of multiple communities' perspectives to inform the design of a hula-based CR intervention. Specific strategies and processes were established to ensure the equity of scientific-clinical and patient- cultural knowledge and perspectives. Multiple methods were used and a flow diagram defined steps for the intervention development. Patient and cultural consultations provided information about the multidimensional benefits of hula and its use in a CR intervention. Clinical and scientific consultations provided specific guidelines for exercise prescription and patient monitoring. Integrating findings from all consultations identified important direction and requirements. Community-based participatory research (CBPR) principles guided a complex collaboration of multiple communities; although time consuming, inclusive consultations provided valuable information and relationships.

This need is a direct result of the aggressive and successful economic development projects undertaken by the tribe in the last decade. While it is possible to contract for additional energy supplies from fossil fuel sources it was the desire of the tribal power company, AHA MACAV Power Service (AMPS) to investigate the feasibility and desirability of producing power from renewable sources as an alternative to increased purchase of fossil fuel generated power and as a possible enterprise to export green power. Renewable energy generated on the reservation would serve to reduce the energy dependence of the tribal enterprises on off reservation sources of energy and if produced in excess of reservation needs, add a new enterprise to the current mix of economic activities on the reservation. Renewable energy development would also demonstrate the tribe’s support for improving environmental quality, sustainability, and energy independence both on the reservation and for the larger community.

    Podoplanin is a mucin-type highly O-glycosylated glycoprotein identified in several somatyic cells: podocytes, alveolar epithelial cells, lymphatic endothelial cells, lymph node stromal fibroblastic reticular cells, osteocytes, odontoblasts, mesothelial cells, glia cells, and others. It has been reported that podoplanin-RhoA interaction induces cytoskeleton relaxation and cell process stretching in fibroblastic cells and osteocytes, and that podoplanin plays a critical role in type I alveolar cell differentiation. It appears that podoplanin plays a number of different roles in contributing to cell functioning and growth by signaling. However, little is known about the functions of podoplanin in the somatic cells of the adult organism because an absence of podoplanin is lethal at birth by the respiratory failure. In this report, we investigated the tooth germ development in podoplanin-knockout mice, and the dentin formation in podoplanin-conditional knockout mice having neural crest-derived cells with deficiency in podoplanin by the Wnt1 promoter and enhancer-driven Cre recombinase: Wnt1-Cre;PdpnΔ/Δmice. In the Wnt1-Cre;PdpnΔ/Δmice, the tooth and alveolar bone showed no morphological abnormalities and grow normally, indicating that podoplanin is not critical in the development of the tooth and bone.

    Creative agriculture is a new agricultural type with originality as a key element, integrating agricultural production activities into creative activities such as culture and art, broadening functions of agriculture and improving added value of agricultural products. Creative agriculture is characterized by external economy, technology integration, art appreciation, high efficiency and value, and it is significant for promoting inheritance of traditional culture, optimal allocation and regeneration of resources, optimal distribution of elements, expansion of agricultural functions, construction of beautiful countryside, cultural construction of rural areas, transformation of agricultural and rural economic growth mode. With agricultural resources as the foundation, sightseeing and leisure agriculture as the breakthrough point, by means of science and technology, many regions in China have explored products of creative agriculture and presented several typical cases of creative agriculture. However, these projects are mostly restricted by problems such as poor development concept, lack of supportive policies, and ineffective industrial integration. Taking Zhejiang Province as an example, we proposed path choice, supportive system and relevant policy suggestions for the development of creative agriculture.

    The success rate for central nervous system (CNS) drug candidates in the clinic is relatively low compared to the industry average across other therapeutic areas. Penetration through the blood-brain barrier (BBB) to reach the therapeutic target is a major obstacle in development. The rapid CNS penetration of salvinorin A has suggested that the neoclerodane nucleus offers an excellent scaffold for developing antiproliferative compounds that enter the CNS. The Liebeskind-Srogl reaction was used as the main carbon-carbon bond-forming step toward the synthesis of quinone-containing salvinorin A analogues. Quinone-containing salvinorin A analogues were shown to have antiproliferative activity against the MCF7 breast cancer cell line, but show no significant activity at the κ-opioid receptors. In an in vitro model of BBB penetration, quinone-containing salvinorin A analogues were shown to passively diffuse across the cell monolayer. The analogues, however, are substrates of P-glycoprotein, and thus further modification of the molecules is needed to reduce the affinity for the efflux transporter.

    This paper summarizes the achievements obtained so far in the context of a research project carried out at the University of Aveiro, Portugal on both numerical and experimental viewpoints concerning Single Point Incremental Forming (SPIF). On the experimental side, the general guidelines on the development of a new SPIF machine are detailed. The innovation features are related to the choice of a six-degrees-of-freedom, parallel kinematics machine, with a high payload, to broad the range of materials to be tested, and allowing for a higher flexibility on tool-path generation. On the numerical side, preliminary results on simulation of SPIF processes resorting to an innovative solid-shell finite element are presented. The final target is an accurate and fast simulation of SPIF processes by means of numerical methods. Accuracy is obtained through the use of a finite element accounting for three-dimensional stress and strain fields. The developed formulation allows for an unlimited number of integration points through its thickness direction, which promotes accuracy without loss of CPU efficiency. Preliminary results and designs are shown and discussions over the obtained solutions are provided in order to further improve the research framework.

    2012-06-01

    With the development of autism therapy, acupuncture, an alternative therapy, is becoming popular for autism children. There have been many papers found about the treatment of autism by acupuncture therapy so far. In the present review, the authors briefly introduce the theoretical basis of autism in traditional Chinese medicine and the application history, and sum up the acupoint prescriptions, effectiveness as well as the assessment tools of acupuncture therapy for autism. It is suggested that acupuncture therapy is a relatively effective therapy for autism children. It has positive roles in improving autistic syndromes without any side-effects, especially in improving language development, daily-life self-care, and social communications. The underlying mechanism of this therapy may be explained by acupuncture intervention induced favorable changes of neurochemistry, cerebral blood flow, and cerebral functional activities. Although there are lots of questions to be answered about acupuncture treatment of autism, we hold a positive opinion that this therapy might be a green effective therapy for autistic children in the future.

    Skin chromophore phantoms are widely used for better understanding of the light interaction with tissue and for calibration of skin diagnostic imaging techniques. In this work, different phantoms were examined and compared in order to find biologically equivalent substances that are the most promising for this purpose. For mimicking the skin medium and layered structure, a fibrin matrix with epidermal and dermal cell inclusion was used. Synthesized bilirubin, red blood cells and nigrosin were taken as absorbers. For spectral analysis of the developed phantoms a computer-aided multispectral imaging system Nuance 2.4 (Cambridge Research & Instrumentation, Inc., USA) was used. In this study, skin phantoms were created using such substances as bilirubin, melanin, haemoglobin and nigrosin Mūsdienās multispektrālās attēlošanas iekārtas izmanto ādas parametru un fizioloģisko procesu aprakstīšanai gan pētniecības, gan diagnostikas nolūkiem.

    Recently, decision tree algorithms have been widely used in dealing with data mining problems to find out valuable rules and patterns. However, scalability, accuracy and efficiency are significant concerns regarding how to effectively deal with large and complex data sets in the implementation. In this paper, we propose an innovative machine learning approach (we call our approach GAIT), combining genetic algorithm, statistical sampling, and decision tree, to develop intelligent decision trees that can alleviate some of these problems. We design our computational experiments and run GAIT on three different data sets (namely Socio- Olympic data, Westinghouse data, and FAA data) to test its performance against standard decision tree algorithm, neural network classifier, and statistical discriminant technique, respectively. The computational results show that our approach outperforms standard decision tree algorithm profoundly at lower sampling levels, and achieves significantly better results with less effort than both neural network and discriminant classifiers.

    Dr. Brian Davis, one of the Cleveland Clinic Foundation's researchers, has been investigating the risk factors related to diabetic foot ulceration, a problem that accounts for 20 percent of all hospital admissions for diabetic patients. He had developed a sensor pad to measure the friction and pressure forces under a person's foot when walking. As part of NASA Lewis Research Center's Space Act Agreement with the Cleveland Clinic Foundation, Dr. Davis requested Lewis' assistance in visualizing the data from the sensor pad. As a result, Lewis' Interactive Data Display System (IDDS) was installed at the Cleveland Clinic. This computer graphics program is normally used to visualize the flow of air through aircraft turbine engines, producing color two- and three-dimensional images.

    Visual understanding of complicated system leads us often to the intuitive enlightenment of the invisible causes of the effect. When it is formulated based on the rigorous mathematics, the produced formula or correlation will be very useful in design and analysis of the engineering system. In this point of view, the tomography technology can be a tool to meet such a purpose. However, the traditional hard ray tomography using high energy radiation cannot meet the case due to heavy shielding structure which obstructs access of the sensing unit to the very complicated and limited space. Therefore, the recent development of the electric tomography is noteworthy in the application to the industrial process monitoring. It has the merit not only of low cost but also of easier access to the limited space than the hard ray tomography.

    The limitations of traditional alloys and the desire for improved performance for components is driving the increased utilization of refractory metals in tile space industry. From advanced propulsion systems to high temperature furnace components for microgravity processing, refractory metals are being used for their high melting temperatures and inherent chemical stability. Techniques have been developed to produce near net shape refractory metal components utilizing vacuum plasma spraying. Material utilization is very high, and laborious machining can be avoided. As-spray formed components have been tested and found to perform adequately. However, increased mechanical and thermal properties are needed. To improve these properties, post processing thermal treatments such as hydrogen sintering and vacuum annealing have been performed. Components formed from alloys of tungsten, rhenium, tantalum, niobium, and molybdenum are discussed and a metallurgical analyses detailing the results are presented. A qualitative comparison of mechanical properties is also included.

    2016-11-01

    Full Text Available INTRODUCTION: Technology allows the creation of dynamic interfaces and graphics, which enables the construction of different scenarios that simulate biochemical events at cellular and molecular level. Furthermore, games have the ability to amuse and stimulate students and thus keeping them interested and receptive. Therefore, digital games must be explored as teaching aids once they have features that enhance the teaching process. OBJECTIVES: This project aimed to develop an educational software that contributes to the understanding of various events taking place in energetic metabolism. MATERIALS AND METHODS: We developed a downloadable educational game in Java, divided into two levels, each of which tackle issues about the Krebs cycle, the respiratory chain and oxidative phosphorylation. Initially, the names of the components of the metabolic process appear randomly on computer screen and the user must follow clues to place them in the right sequence, until all the biochemical reactions are complete. In next phase, there is a quiz about details and clinical correlates related to the theme of the game. Finally, students have to answer a form in order to verify acceptance and relevance of the game. DISCUSSION AND RESULTS: The game was applied to 40 medical students from UFF. The game’s subject matter and its difficulty were analyzed and more than 40% of students classified both respiratory chain and Krebs cycle as difficult. These findings highlight the need to establish new methods to enhance the teaching and learning processes and decrease the students’ difficulties, which is the game’s purpose. The game was very highly rated by students once they evaluated the game as an excellent educational aid and 92% of students agreed that it complements the content discussed in classroom. Finally, 97,5% of students said they would play again. CONCLUSION: Therefore, educational games could be an excellent tool to optimize learning.

    The Early Growth and Development Study is a prospective adoption study of birth parents, adoptive parents, and adopted children recruited in two cohorts (N = 561 triads). The primary study aims are to examine how family, peer, and contextual processes affect children's adjustment, and to examine their interplay (mediation, moderation) with genetic influences. Participants were recruited through adoption agencies located throughout the United States following the birth of a child. Assessments are ongoing, in 9-month intervals until the child reaches 3 years of age and in 1-year intervals thereafter through age 9. Data collection includes the following primary constructs: child temperament, social behavior, school performance, mental health, and health; birth and adoptive parent personality characteristics, mental health, competence, stress, health, context, substance use, parenting, and marital relations; and pregnancy use of drugs and maternal stress during pregnancy. DNA and salivary cortisol samples have also been collected. Analyses have indicated evidence for genotype-environment interactions during early childhood. Study procedures, sample representativeness (including tests of potential confounds in the adoption design), and an overview of findings to date are summarized, and future plans are described.

    The main mission of military medicine in the world is to support the health and treatment of the military in relation to issues, risks, injuries and diseases that arise due to the specific occupational conditions. The current study was carried out with the aim of determining the required skills of military physicians to define and determine the required training modules. The study was a qualitative research. Semi-structured interviews were used to collect the data and qualitative content analysis was used to analyze the data. The study population included all the professors and experts in the field of military medicine and medical sciences at the medical universities of Tehran. Snowball sampling technique was used to sample the study participants. Based on the results, the required skills of military physicians in 5 categories and 29 sub- categories were identified; then based on the identified skills, 60 training modules at two introductory and advanced levels were determined including 39 introductory levels and 21 advanced levels. We can conclude that some of the important skills that military physicians need and can achieved through training have not been provided in any educational program and to achieve such skills and capabilities, other programs should be developed and modular training can be one of them.

    The University of Michigan has been commissioned to conduct one of the largest environmental epidemiology studies (700 residents) of dioxin exposure among the population of Michigan to describe the pattern of serum dioxin levels among adults and to understand the factors that explain variation in serum dioxin levels. The study is being undertaken (2004-2006) in response to concerns among the population of Midland and Saginaw Counties that dioxins from the Dow Chemical Company facilities in Midland have resulted in contamination of areas of the City of Midland and have contaminated the sediments in the Tittabawassee River flood plain. There is concern that body burdens of dioxins are elevated because of environmental contamination. The appropriate way to respond to these concerns is to measure the serum dioxin levels in a probability sample of the population in the region and to estimate each individual's past exposure to various factors that are believed to contribute to the body burden of dioxins. By measuring factors that reflect potential exposure to dioxins through air, water, soil, food intake, occupations, and various recreational activities, we can identify the factors that correlate with (and explain variation in) serum dioxin levels. The central goal of the study is to determine which factors explain variation in serum dioxin levels, and to quantify how much variation each factor explains. This paper provides information on the planning phase, study scope and objectives.

    This study longitudinally compared activity in the frontal cortex during a spatial working memory task between 5-year-old and 7-year-old children using near-infrared spectroscopy. Eight children participated in this study twice, once at 5 years and once at 7 years of age. Behavioral analysis showed that older children performed the working memory task more precisely and more rapidly than younger children. Near-infrared spectroscopy analysis showed that right hemisphere dominance was observed in older children, whereas no hemispheric difference was apparent in younger children. Children with strengthened lateralization showed improved performance from 5 to 7 years. We therefore offer the first demonstration of the developmental changes in frontal cortical activation during spatial working memory tasks during the preschool period.

    Full Text Available The ontogeny of executive functions is essential in explaining differential and normative developmental trends. Executive functions must be studied from an early age given their consequential effects on mental flexibility, monitoring information, planning, and cognitive control. We propose a differential study in alternative developmental courses through observing typical babies, Down syndrome babies, and babies with risk-factors at birth (due to low weight or to congenital hypothyroidism. Applymg Systematic Observational Methodology, spontaneous babies' activity was registered. The results indicated that: a Typical babies showed better shifting and action flexibility in order to obtain a goal, thus better results; b Among the higher risk-babies, the lower efficacy in executive functioning was observed in underweight babies. Those with hypothyroidism were more in line with the typical babies; c Underweight babies showed a good level of combining actions but they obtained inferior results; d Down syndrome babies displayed more executive functioning difficulty, lower flexibility, high perseveration and less error detection.

    The safety climate of an organization is considered a leading indicator of potential risk for railway organizations. This study adopts the perceptual measurement-individual attribute approach to investigate the safety climate of a railway organization. The railway safety climate attributes are evaluated from the perspective of railway system staff. We identify four safety climate dimensions from exploratory factor analysis, namely safety communication, safety training, safety management and subjectively evaluated safety performance. Analytical results indicate that the safety climate differs at vertical and horizontal organizational levels. This study contributes to the literature by providing empirical evidence of the multilevel safety climate in a railway organization, presents possible causes of the differences under various cultural contexts and differentiates between safety climate scales for diverse workgroups within the railway organization. This information can be used to improve the safety sustainability of railway organizations and to conduct safety supervisions for the government.

    Full Text Available Indomethacin suppositories were prepared by using water-soluble and oil soluble suppository bases, and evaluated for in vitro release by USP I and modified continuous flow through bead bed apparatus. Effect of the Tween 80 (1% and 5% was further studied on in vitro release of the medicament. Release rate was good in water-soluble suppositories bases in comparison to oil soluble suppositories bases. Release was found to be greater in modified continuous flow through bead bed apparatus. When surfactant was used in low concentration then release rate was much greater, as compared to high concentration. When stability studies were performed on the prepared indomethacin suppositories it was found that suppositories made by water-soluble base had no significant changes while suppositories prepared by oil soluble bases, had some signs of instability.

  18. Development of cataract caused by diabetes mellitus: Raman study

    2005-06-01

    Diabetes mellitus succeeded by diabetic cataract was induced to experimental animals (Wistar rats) by applying an Alloxan injection. Eye properties deterioration were monitored from clinical standpoint and using Raman and infrared spectroscopies. All cases of developed cataract were followed by important changes in vibrational spectra, but Raman spectroscopy proved to be more useful because of larger number of resolved bands. Each kth Raman spectrum of diseased lens (in our notation k denotes disease age and cataract degree as described in chapter Alloxan diabetes) can be expressed as a sum of the Raman spectrum of healthy lens, I R, multiplied by a suitable constant ck, and the fluorescent background spectrum, I FB. We introduce the ratio of integrated intensities IFB and ck* IR as a physical parameter called fluorescent background index F FB. It turns out that FFB grows as cataract progresses and has its maximum at approx. 4, whence it decreases. FFB values are larger for 200-1800 cm -1 spectral interval than for 2500-4000 cm -1 interval. In the same manner another quantity called water band index FW is defined for each Raman spectrum of diseased lens in the 2800-3730 cm -1 interval. It is the ratio of the integrated intensity from 3100 to 3730 cm -1 (water band interval) divided by the integrated intensity of the 2800-3100 cm -1 interval (C-H stretching region). FW increases monotonously with cataract progression with maximum at the end of monitored period (5 months). These two indices helped us to formulate a model describing disease development from the earliest molecular changes to its macroscopic manifestation. As glucose and other small saccharide molecules enter the lens tissue, they bind to crystallin and other proteins via O- and S-glycosidic linkages which occur probably at tyrosine and cystein sites. In Raman spectrum this corresponds to broad bands at 540 and 1100 cm -1 which grow together with the fluorescent background, because both contributions

    The increased prevalence of malocclusions represents a secular trend attributed to the interaction of genetic and environmental factors. The analysis of factors related to the causes of these changes is essential for planning public health policies aimed at preventing and clinically intercepting malocclusion. This study investigated the sucking habits, nocturnal mouth breathing, as well as the relation of these factors with malocclusion. This is a longitudinal study in which 80 mother-child pairs were monitored from the beginning of pregnancy to the 30th month after childbirth. Home visits for interviews with the mothers were made on the 12th, 18th and 30th months of age. Finger sucking, pacifier sucking, bottle feeding, breastfeeding and nocturnal mouth breathing, were the variables studies. On the 30th month, clinical examinations were performed for overjet, overbite and posterior crossbite. A previously calibrated single examiner (Kappa coefficient = 0.92) was responsible for all examinations. Data were analyzed using the chi-squared or Fisher's exact tests, at a significance level of 5%. Bottle feeding was the most prevalent habit at 12, 18 and 30 months (87.5%; 90% and 96.25%, respectively). Breastfeeding was 40%, 25% and 12.50% at 12, 18 and 30 months, respectively. Nearly 70% of the children in this study had some sort of malocclusion. Pacifier sucking habit at 12, 18 and 30 months of age was associated with overjet and open bite; and at 30 months, an association with overbite was also observed. Finger sucking habit and breastfeeding at 12, 18 and 30 months were also associated with overjet and open bite. The posterior crossbite was associated with bottle feeding at 12 and 30 months, and nocturnal mouth breathers at 12 and 18 months. Sucking habits, low rates of breastfeeding, and nocturnal mouth breathing were risk factors for malocclusion.

    The increasing interest in the study of the antioxidant activity of different objects is caused by an unbalance between the formation of reactive oxygen species (ROS) and the performance of the antioxidant system in humans under certain conditions, which leads to oxidative stress and pathological states of the organism. This article presents a brief critical review of the methods that are used to measure integrated antioxidant activity (AOA). It is shown that the most promising methods for measuring AOA are electrochemical ones, particularly potentiometry, as it best fits the nature of the processes causing oxidative stress. The article gives the theoretical rational for requirements that an oxidizer of antioxidants (AO) should meet. The work presents the thermodynamic grounds for the use of an earlier proposed mediator system, kinetics of chemical reactions between AO and the mediator system. In order to confirm reliability and accuracy of the results, numerous correlation studies were conducted, aiming to compare the data obtained with the use the proposed method and independent analytical methods. The article presents the results of the potentiometric study of AOA for a variety of objects, including individual antioxidant → nutritional supplements → food → blood and blood fractions.

    Sediment source study is valuable for watershed sediment budget, sediment control in channels, soil erosion model validation and benefits evaluation of soil and water conservation. As one of the methods to make clear the sediment sources, fingerprinting has been proven effective, and hence has been adopted in different countries over the world. This paper briefly introduced the fingerprinting method in models, diagnostic sediment properties, applied regions, spatial and temporal scales, and classification of sediment source types. Combining with environmental radionuclides as the time makers (such as 137Cs and 210Pb), the sediment source history has been possible by virtue of this method. However, some uncertainties are waiting for the confirmative answers while introducing fingerprinting technique to sediment related studies: the efficient sampling strategies through linking sediment source and fingerprint properties need to be clearer, the spatial scale links (up-scaling and down-scaling) should be provided with detailed methods, the model calibration is necessary to be updated to improve the estimated precision. (This paper is a contribution to the project of National Natural Science Foundation of China (No. 41501299), the non-profit project of Ministry of Water Resources of China (No. 201501045), and the project of Youth Scientific Research of China Institute of Water Resources and Hydropower Research (Using fingerprinting technique to study sediment source in a typical small watershed of black soil region in northeast China))

    The isolated counterrotating high speed turboprop noise prediction program was compared with model data taken in the GE Aircraft Engines Cell 41 anechoic facility, the Boeing Transonic Wind Tunnel, and in NASA-Lewis' 8x6 and 9x15 wind tunnels. The predictions show good agreement with measured data under both low and high speed simulated flight conditions. The installation effect model developed for single rotation, high speed turboprops was extended to include counterotation. The additional effect of mounting a pylon upstream of the forward rotor was included in the flow field modeling. A nontraditional mechanism concerning the acoustic radiation from a propeller at angle of attach was investigated. Predictions made using this approach show results that are in much closer agreement with measurement over a range of operating conditions than those obtained via traditional fluctuating force methods. The isolated rotors and installation effects models were combines into a single prediction program, results of which were compared with data taken during the flight test of the B727/UDF engine demonstrator aircraft. Satisfactory comparisons between prediction and measured data for the demonstrator airplane, together with the identification of a nontraditional radiation mechanism for propellers at angle of attack are achieved.

    We describe an innovative program at the University of California, Davis for students to engage in clinical needs finding. Using a team-based approach, students participated in clinical rotations to observe firsthand the needs of clinicians at the university affiliated medical center. The teams were asked to develop documentary-style videos to capture key experiences that would allow future viewers to use the videos as “virtual” clinical rotations. This was conceived as a strategy to allow students in prohibitively large classes, or students in programs at institutions without associated medical or veterinary school programs, to experience clinical rotations and perform needs assessments. The students' perspectives on the experience as well as instructor analysis of best practices for this type of activity are presented and discussed. We found that the internship experience was valuable to the students participating, by not only introducing the practice of needs finding but for increasing the students' confidence in the practice of engineering design and their ability to work independently. The videos produced were of such high quality that instructors from other institutions have requested copies for instructional use. Virtual clinical rotations through video experiences may provide a reasonable substitute for students who do not have the ability to participate in rotations in person. PMID:23483373

    Full Text Available The flexibility of the MOOC service allows students to learn at their own time, place and pace, enhancing continuous communication and interaction between all participants in knowledge and community building. This model especially benefits people with disabilities, which can improve therefore their level of employability and social inclusion, reaching a better quality of life. Unfortunately the access to MOOC platforms present severe barriers: there is a lack of accessibility on the learning resources, the communicating tools and personalized user interfaces. All these issues add extra difficulties such as the need to develop specific digital or even social skills for students with functional diversity. In this context, MOOCs are leading a revolutionary computer and mobile-based scenario along with social technologies that will emerge new kinds of learning applications that enhance communication and collaboration processes. For that reason, this paper describes the need for designing an information model and related specifications to support a new strategy for delivering accessible MOOC courses to learners with special needs, in terms of their preferences and context of use based on a particular application profile. This user profile’s design is based on standard metadata schemas, data that provides information about other data, regarding the achievement of accessibility from content to user preferences.

Areas  of regional import to sub-Saharan Africa, such as HIV/AIDs and tuberculosis diagnosis, are also apparent in a review of the available literature. Irrespective of the targets, the challenge to the effective deployment of such sensors remains shaped by social and economic realities such that the requirements thereof are for low-cost and universally easy to operate devices for field settings. While it is difficult to disentangle the intertwined roles of national policy, grant funding availability and, certainly, of global trends in shaping areas of emphasis in research, most notable is the strong role that nanotechnology, and to a certain extent biotechnology, plays in research regarding biosensor construction.

    In this paper we consider two CW solid state laser approaches to a 589 nm LGS system. Both are based on the technique of sum-frequency generation, but differ in the cavity architecture. Both technologies are very promising and are worth of further consideration. This preliminary proposal is intended to encompass both designs. A down select shall be performed early in the project execution to focus on the most promising option. The two design options consist of: (1) A dual-frequency resonator with intra-cavity doubling in LB0 offers the promise of a simple architecture and may scale more easily to high power. This design has been shown to be highly reliable, efficient and high power when used in frequency-doubled Nd:YAG lasers for programs at LLNL and in commercial products. The challenge in this design is the demonstration of a high power13 18 nm oscillator with adequate suppression of the 1064 nm line. (2) A MOPA based design uses commercial low power oscillators to produce both wavelengths, then amplifies the wavelengths before doubling. This design requires the demonstration of a 1318 nm amplifier, though the design is scaled from a kW CW amplifier already delivered to a customer at a different wavelength. The design must also demonstrate high power scaling of sum-frequency generation in the relatively new nonlinear material, PPLN. The first step in the process would be to further evaluate the two conceptual options for technical feasibility, cost and constructability. Then a down selection to one design would be conducted. Finally, R&D on that design would then proceed. Minimal testing should be required for this selection. The majority of the funding received would be allocated to development of the design selected.

    Myocardial preservation during open heart surgeries and harvesting for transplant are of great importance. The heart at the end of procedure has to resume its functions as soon as possible. All cardioplegic solutions are based on potassium for induction of cardioplegic arrest. To assess a cardioplegic solution with no potassium addition to the formula with two other commercially available cardioplegic solutions. The comparative assessment was based on cytotoxicity, adenosine triphosphate myocardial preservation, and caspase 3 activity. The tested solution (LIRM) uses low doses of sodium channel blocker (lidocaine), potassium channel opener (cromakalin), and actin/myosin cross bridge inhibitor (2,3-butanedione monoxime). Wistar rats underwent thoracotomy under mechanical ventilation and three different solutions were used for "in situ" perfusion for cardioplegic arrest induction: Custodiol (HTK), Braile (G/A), and LIRM solutions. After cardiac arrest, the hearts were excised and kept in cold storage for 4 hours. After this period, the hearts were assessed with optical light microscopy, myocardial ATP content and caspase 3 activity. All three solutions were evaluated for direct cytotoxicity with L929 and WEHI-164 cells. The ATP content was higher in the Custodiol group compared to two other solutions (P<0.05). The caspase activity was lower in the HTK group compared to LIRM and G/A solutions (P<0.01). The LIRM solution showed lower caspase activity compared to Braile solution (P<0.01). All solutions showed no cytotoxicity effect after 24 hours of cells exposure to cardioplegic solutions. Cardioplegia solutions without potassium are promised and aminoacid addition might be an interesting strategy. More evaluation is necessary for an optimal cardioplegic solution development.

  13. Demographic approaches to studies of canopy development in plants

    Via their modular structure, plants operate at two levels in their population biology - the level of the individual and that of the parts which make up an individual; the genet and the ramet (sensu Harper). Thus, possibilities exist to describe the growth of plants as a population-like process rather than via the conventional notions of dry matter change and relative growth rate. This paper gives three applications of this idea. The first analyses the temporal changes in the number of vegetative and flowering shoot meristems of plants grown in different soil volumes. The main conclusion was that the `trade-off` between the production of flowering or vegetative meristems was less influenced by root restriction than was the overall of meristems. This was higher for plants grown in the largest pots. The second example is an analysis of pruning apple trees where, using bud-counts on pruned and unpruned trees, bud distribution between branches was analysed. Pruning restored a normal distribution, whereas unpruned plants had a skewed distribution of buds per branch. The final, related notion, is the development of a matrix model of bud pruning based on the prediction of the maximum harvestable yield of an animal population. Pruning and harvesting are analogous processes since both involve removal of some individuals, thus affecting the fecundity or productivity of remaining members of the population. Optimal pruning or harvesting estimates, on the basis of the age-dependent fecundity and survival of individuals in the population, the maximum number of individuals which can be removed without reducing the overall population growth rate below unity. At this point, all harvested individuals or pruned buds are replaced in the next time step. The discussion highlights directions for extending this corollary further. (author)

  15. Beam dynamics studies to develop LHC luminosity model

    CERN Document Server

    Campogiani, Giovanna; Papaphilippou, Ioannis

    The thesis project aims at studying the different physical processes that are impacting luminosity, one of the key figures of merit of a collider operation. In particular the project focuses on extracting the most relevant parameters for the high-energy part of the model, which is mostly dominated by the beam-beam effect. LHC luminosity is degraded by parasitic collisions that reduce the beam lifetime and the particles stability in the collider. This instability is due to the non-linear effects of one beam electromagnetic field on another in the interaction region. Such parasitic encounters can be as many as 16 per interaction region, piling up to around 180 000 per second. Our goal is to study the evolution of charge density distribution in the beam, by tracking particles through a symplectic integrator that includes the beam-beam effect. In particular we want to obtain data on the halo particles, which are more sensible to instability, to better characterise the beam lifetime and monitor the luminosity evol...

    In this study, diphtheria, tetanus and pertussis vaccine components were prepared as the formulations of diphtheria-tetanus-pertussis (DTP), diphtheria-tetanus (DT) for children, diphtheria-tetanus (Td) for adults, and tetanus toxoid (TT), respectively. Alhydrogel-adsorbed vaccines prepared to contain the stabilizing substances were lyophilized and the immunogenicity tests were carried out both in vivo and in vitro. The potencies of the tetanus component of the vaccines were obtained by the lethal challenge test in mice. The values were found as 144.86 IU/ml for lyophilized adsorbed (LA)-DTP, 116.5 IU/ml for LA-DT, 98.25 IU/ml for LA-Td and 96.2 IU/ml for LA-TT. Anti-tetanus IgG and anti-diphteria IgG levels determined by ELISA method were found high in the sera taken from the mice immunized with the above-mentioned vaccines. Anti-B.pertussis fimbria IgG antibody levels were also high by both ELISA and microagglutination tests. The test preparations were then compared to adsorbed liquid vaccines and it was shown that the components were quite stable in the lyophilized formulations. It was concluded that the formulations prepared in this study can be used as standard vaccines after being calibrated against World Health Organization standards.

    Recent studies have shown evidence of positive concurrent relationships between children's use of text message abbreviations ('textisms') and performance on standardized assessments of reading and spelling. This study aimed to determine the direction of this association. One hundred and nineteen children aged between 8 and 12 years were assessed on measures of general ability, reading, spelling, rapid phonological retrieval, and phonological awareness at the beginning and end of an academic year. The children were also asked to provide a sample of the text messages that they sent over a 2-day period. These messages were analyzed to determine the extent to which textisms were used. It was found that textism use at the beginning of the academic year was able to predict unique variance in spelling performance at the end of the academic year after controlling for age, verbal IQ, phonological awareness, and spelling ability at the beginning of the year. When the analysis was reversed, reading and spelling ability were unable to predict unique variance in textism usage. These data suggest that there is some evidence of a causal contribution of textism usage to spelling performance in children aged 8-12 years. However, when the measure of rapid phonological retrieval (rapid picture naming) was controlled in the analysis, the relationship between textism use and spelling ability just failed to reach statistical significance, suggesting that phonological access skills may mediate some of the relationship between textism use and spelling performance. ©2011 The British Psychological Society.

    Alternative vectors to deliver viable cells of probiotics, to those conferring limited resistance to gastrointestinal conditions, still need to be sought. Therefore the main goal of the study was to develop tablets able to protect entrapped probiotic bacteria from gastric acidity, thus providing an easily manufacturing scale-up dosage form to deliver probiotics to the vicinity of the human colon. Whey protein concentrate microparticles with Lactobacillus paracasei L26 were produced by spray-drying and incorporated in tablets with cellulose acetate phthalate and sodium croscarmellose. The viability of L. paracasei L.26 throughout tableting as well as its gastric resistance and release from the tablets were evaluated. Storage stability of L. paracasei L26 tablets was also performed by evaluation of viable cells throughout 60 days at 23°C and 33% relative humidity. A decrease of approximately one logarithmic cycle was observed after the acid stage and the release of L. paracasei L26 from the tablets occurred only after 4 h in the conditions tested. Microencapsulated L. paracasei L26 in tablets revealed some susceptibility to the storage conditions tested since the number of viable cells decreased 2 log cycles after 60 days of storage. However, the viability of L. paracasei L26 after 45 days of storage did not reveal significant susceptibility upon exposure to simulated gastrointestinal conditions. The developed probiotic tablets revealed to be potential vectors for delivering viable cells of L. paracasei L26 and probably other probiotics to persons/patients who might benefit from probiotic therapy.

    Full Text Available This writing is a preliminary study to condition of primary education facilities in Indonesia, and then comparing these with theories as well as various relevant cases aimed to know the problem more obviously. Basically, there is difference between primary education facilities in Indonesia with those in developed countries. Meanwhile on the other hand, the condition as well as the completion of education facility is actually as the main factor contributes to address the purpose of learning process. If building design, interior and also site plan were dynamic in form, space, colour and tools, those would be probably more stimulate activity and influence into the growth of students. However, lastly, it is still required further analysis, as an example analysis to student's behaviour in spaces of learning environment, more detail and within enough time, not only at indoor but also at outdoor.

    Full Text Available The article presents an on-going discussion whether learners can become self-regulated during their studies. Four stages of self-regulation have been identified: initial self-projecting, self-monitoring, self-reflecting and final self-projecting stage. The results of students’ feedback questionnaire which included SWOT analysis, the analysis of motivational factors and self-reflection on the learning outcomes learning are analysed. A shift from self-monitoring stage to self-reflecting stage is revealed. The paper also describes students’ willingness to self-monitor their learning process when they are asked to take responsibility for learning outcomes. The con-clusion is drawn that students find it difficult to self-monitor when given full responsibility. It is also revealed that writing reflection pages help to self-reflect on the learning outcomes.

    This research investigated youth leadership experiences of adolescent girls who participated in a comprehensive feminist-based leadership program. This qualitative study utilized a grounded theory approach to understand changes that occurred in 10 female adolescent participants. The words of the participants revealed that initially they viewed leadership in traditional terms and were hesitant to identify themselves as leaders or to see themselves included within their concepts of leadership. Following the program their view of leadership expanded and diversified in a manner that allowed for inclusion of themselves within it. They spoke with greater strength and confidence and felt better positioned and inspired to act as leaders. Participants identified having examples of women leaders, adopting multiple concepts of leadership, and participating in an environment of mutual respect and trust as factors that contributed to their expanded conceptualization.

    Full Text Available Abstract Background It is difficult to systematically search for literature relevant to palliative care in general medical journals. A previously developed search filter for use on OVID Medline validated using a gold standard set of references identified through hand searching, achieved an unacceptably low sensitivity (45.4%. Retrieving relevant literature is integral to support evidence based practice, and understanding the nature of the incorrectly excluded citations (false negatives using the filter may lead to improvement in the filter's performance. Methods The objectives were to describe the nature of subjects reflected in the false negative citations and to empirically improve the sensitivity of the search filter. A thematic analysis of MeSH terms by three independent reviewers was used to describe the subject coverage of the missed records. Using a frequency analysis of MeSH terms, those headings which could individually contribute at least 2.5% to sensitivity (occurring 19 or more times were added to the search filter. All previously run searches were rerun at the same time as the revised filter, and results compared. Results Thematic analysis of MeSH terms identified thirteen themes reflected in the missing records, none of them intrinsically palliative. The addition of six MeSH terms to the existing search filter (physician-patient relations, prognosis, quality of life, survival rate, treatment outcome and attitude to health led to an increase in sensitivity from 46.3% to 64.7%, offset by a decrease in precision from 72.6% to 21.9%. Conclusion The filter's sensitivity was successfully increased using frequency analysis of MeSH terms, offset by a decrease in precision. A thematic analysis of MeSH terms for the false negative citations confirmed the absence of any intrinsically palliative theme or term, suggesting that future improvements to search filters for palliative care literature will first depend on better identifying how

    In order to replicate the fracture behavior of the intact human skull under impact it becomes necessary to develop a material having the mechanical properties of cranial bone. The most important properties to replicate in a surrogate human skull were found to be the fracture toughness and tensile strength of the cranial tables as well as the bending strength of the three-layer (inner table-diplöe-outer table) architecture of the human skull. The materials selected to represent the surrogate cranial tables consisted of two different epoxy resins systems with random milled glass fiber to enhance the strength and stiffness and the materials to represent the surrogate diplöe consisted of three low density foams. Forty-one three-point bending fracture toughness tests were performed on nine material combinations. The materials that best represented the fracture toughness of cranial tables were then selected and formed into tensile samples and tested. These materials were then used with the two surrogate diplöe foam materials to create the three-layer surrogate cranial bone samples for three-point bending tests. Drop tower tests were performed on flat samples created from these materials and the fracture patterns were very similar to the linear fractures in pendulum impacts of intact human skulls, previously reported in the literature. The surrogate cranial tables had the quasi-static fracture toughness and tensile strength of 2.5 MPa√ m and 53 ± 4.9 MPa, respectively, while the same properties of human compact bone were 3.1 ± 1.8 MPa√ m and 68 ± 18 MPa, respectively. The cranial surrogate had a quasi-static bending strength of 68 ± 5.7 MPa, while that of cranial bone was 82 ± 26 MPa. This material/design is currently being used to construct spherical shell samples for drop tower and ballistic tests.

    1991-01-01

    Theory predicts vortex instability when subjected to certain types of disturbances. It was desired to build a device which could introduce controlled velocity perturbations into a trailing line vortex in order to study the effects on stability. A perturbation generator was designed and manufactured which can be attached to the centerbody of an airfoil type vortex generator. Details of design tests and manufacturing of the perturbation generator are presented. The device produced controlled perturbation with frequencies in excess of 250 Hz. Preliminary testing and evaluation of the perturbation generator performance was conducted in a 4 inch cylindrical pipe. Observations of vortex shedding frequencies from a centerbody were measured. Further evaluation with the perturbation generator attached to the vortex generator in a 2 x 3 foot wind tunnel were also conducted. Hot-wire anemometry was used to confirm the perturbation generator's ability to introduce controlled frequency fluctuations. Comparison of the energy levels of the disturbances in the vortex core was made between locations 42 chord lengths and 15 chord lengths downstream.

    2017-06-26

    Racial identity invalidation, others' denial of an individual's racial identity, is a salient racial stressor with harmful effects on the mental health and well-being of Multiracial individuals. The purpose of this study was to create a psychometrically sound measure to assess racial identity invalidation for use with Multiracial individuals (N = 497). The present sample was mostly female (75%) with a mean age of 26.52 years (SD = 9.60). The most common racial backgrounds represented were Asian/White (33.4%) and Black/White (23.7%). Participants completed several online measures via Qualtrics. Exploratory factor analyses revealed 3 racial identity invalidation factors: behavior invalidation, phenotype invalidation, and identity incongruent discrimination. A confirmatory factor analysis provided support for the initial factor structure. Alternative model testing indicated that the bifactor model was superior to the 3-factor model. Thus, a total score and/or 3 subscale scores can be used when administering this instrument. Support was found for the reliability and validity of the total scale and subscales. In line with the minority stress theory, challenges with racial identity mediated relationships between racial identity invalidation and mental health and well-being outcomes. The findings highlight the different dimensions of racial identity invalidation and indicate their negative associations with connectedness and psychological well-being.

  12. Developing fiber specific promoter-reporter transgenic lines to study the effect of abiotic stresses on fiber development in cotton.

    Directory of Open Access Journals (Sweden)

    Junping Chen

    Full Text Available Cotton is one of the most important cash crops in US agricultural industry. Environmental stresses, such as drought, high temperature and combination of both, not only reduce the overall growth of cotton plants, but also greatly decrease cotton lint yield and fiber quality. The impact of environmental stresses on fiber development is poorly understood due to technical difficulties associated with the study of developing fiber tissues and lack of genetic materials to study fiber development. To address this important question and provide the need for scientific community, we have generated transgenic cotton lines harboring cotton fiber specific promoter (CFSP-reporter constructs from six cotton fiber specific genes (Expansin, E6, Rac13, CelA1, LTP, and Fb late, representing genes that are expressed at different stages of fiber development. Individual CFSP::GUS or CFSP::GFP construct was introduced into Coker 312 via Agrobacterium mediated transformation. Transgenic cotton lines were evaluated phenotypically and screened for the presence of selectable marker, reporter gene expression, and insertion numbers. Quantitative analysis showed that the patterns of GUS reporter gene activity during fiber development in transgenic cotton lines were similar to those of the native genes. Greenhouse drought and heat stress study showed a correlation between the decrease in promoter activities and decrease in fiber length, increase in micronaire and changes in other fiber quality traits in transgenic lines grown under stressed condition. These newly developed materials provide new molecular tools for studying the effects of abiotic stresses on fiber development and may be used in study of cotton fiber development genes and eventually in the genetic manipulation of fiber quality.

    Full Text Available The clean development of China’s power supply structure has become a crucial strategic problem for the low-carbon, green development of Chinese society. Considering the subsistent developments of optimized allocation of energy resources and efficient utilization, the urgent need to solve environmental pollution, and the continuously promoted power market-oriented reform, further study of China’s power structure clean development has certain theoretical value. Based on the data analysis, this paper analyzes the key factors that influence the evolution process of the structure with the help of system dynamics theory and carries out comprehensive assessments after the construction of the structure evaluation system. Additionally, a forecasting model of the power supply structure development based on the Vector Autoregressive Model (VAR has been put forward to forecast the future structure. Through the research of policy review and scenario analysis, the paths and directions of structure optimization are proposed. In this paper, the system dynamics, vector autoregressive model (VAR, policy mining, and scenario analysis methods are combined to systematically demonstrate the evolution of China’s power structure, and predict the future direction of development. This research may provide a methodological and practical reference for the analysis of China’s power supply structure optimization development and for theoretical studies.

Any drastic and abrupt changes in this system can have repercussion beyond mitigation in form of natural disasters. The present study furnish socio-economic vulnerability mapping of the Bhagirathi basin through computation of the Socio vulnerability Index (SoVI). SVI correlates vulnerability to natural disasters to socio - economic development and illustrates how developmental parameters alter equation of potential effect and recovery in event of a natural catastrophe in the study region. An analytical framework has been imparted to understand possible triggering factors of natural disasters. Built up area expansion; land use land cover change (LULCC) - deforestation, conversion of forested land into agricultural land and residential settlements, and dam project area; road network development; urbanization; population growth & migration and pilgrimage activities are major drivers which put burden on limited carrying capacity of the natural resources. A guideline for policy making has been presented for an integrated and wholesome development incorporating regional developmental aspiration of the people and ingredients of sustainable development. Keywords: Social Vulnerability Index; Land Use Land Cover Change; Conservation; Sustainable development.

    The Twins Early Development Study (TEDS) is a large longitudinal sample of twins born in England and Wales between 1994 and 1996. The focus of TEDS has been on cognitive and behavioral development, including difficulties in the context of normal development. TEDS began when multiple births were identified from birth records and the families were invited to take part in the study; 16,810 pairs of twins were originally enrolled in TEDS. More than 10,000 of these twin pairs remain enrolled in the study to date. DNA has been collected for more than 7,000 pairs, and genome-wide genotyping data for two million DNA markers are available for 3,500 individuals. The TEDS families have taken part in studies when the twins were aged 2, 3, 4, 7, 8, 9, 10, 12, 14, and 16 years of age. Data collection is currently underway to assess the adult destinations of the twins as they move from school to university and the workplace. Between January 2012 and December 2014, all of the TEDS twins will turn 18, and the study will transition to an adult sample. TEDS represents an outstanding resource for investigating the developmental effects of genes and environments on complex quantitative traits from childhood to young adulthood and beyond.

  20. Integrating the results of user research into medical device development: insights from a case study

    Full Text Available Abstract Background It is well established that considering users is an important aspect of medical device development. However it is also well established that there are numerous barriers to successfully conducting user research and integrating the results into product development. It is not sufficient to simply conduct user research, it must also be effectively integrated into product development. Methods A case study of the development of a new medical imaging device was conducted to examine in detail how users were involved in a medical device development project. Two user research studies were conducted: a requirements elicitation interview study and an early prototype evaluation using contextual inquiry. A descriptive in situ approach was taken to investigate how these studies contributed to the product development process and how the results of this work influenced the development of the technology. Data was collected qualitatively through interviews with the development team, participant observation at development meetings and document analysis. The focus was on investigating the barriers that exist to prevent user data from being integrated into product development. Results A number of individual, organisational and system barriers were identified that functioned to prevent the results of the user research being fully integrated into development. The user and technological aspects of development were seen as separate work streams during development. The expectations of the developers were that user research would collect requirements for the appearance of the device, rather than challenge its fundamental concept. The manner that the user data was communicated to the development team was not effective in conveying the significance or breadth of the findings. Conclusion There are a range of informal and formal organisational processes that can affect the uptake of user data during medical device development. Adopting formal decision
