    Full text: The Police Scientific Development Branch (Pdb) of the UK Home Office evaluates technologies, develops equipment and detection standards for the police and security communities. PSDB's guidance helps to protect critical sites, including nuclear sites, in the United Kingdom. PSDB evaluates doors, walls, fences, locks, glazing and other barrier to determine whether they meet national and European standards against conventional physical attack. PSDB also evaluates intruder-detection systems. If solutions for security problems do not exist commercially, it might help to develop them. Examples include computer machine-vision systems to guide a pan-tilt-zoom camera automatically, and to assess intruder alarms. PSDB's automatic alarm verification system (AMETHYST) is now being installed for test at a nuclear power station on England's south coast. PSDB has used its analysis of the effects of exploding bombs on building materials to influence building codes. The PSDB also evaluates technologies for crime investigation, surveillance, explosive detection and bomb search. PSDB uses its experience to help train security practitioners to select, specify, and audit security at critical sites, including sites that handle nuclear materials. PSDB's technologies and advice have helped to protect the UK against terrorist attacks. Its expertise can be made available to help meet other European needs. (author)

    Full Text Available Essential typological features of scientific schools are investigated, paying special attention to informational and communicational aspects of the problem. Peculiarities of scientific research organization in printing and publishing branches are revealed. A specific character of branch science consisting in the fact of close connection between scientific school formation and the activities of specialized higher education institutions is noted. The process of the establishment and development of the Lviv-Kyiv school of printing industry technologies, particularly regarding activities on development and application of photopolymer printing forms in printing production is analysed. On the example of the formation and the activity of the Lviv-Kyiv school of printing and publishing technologies the features of scientific school are listed. It is shown that scientific schools are formed under the influence of society demands, by the logic of science and practice development providing long-term fundamental and applied research and having essential achievements of public recognition in the homeland and abroad. Given this the functions of scientific schools are defined.

  3. International scientific cooperation during the 1930s. Bruno Rossi and the development of the status of cosmic rays into a branch of physics.

    During the 1920s and 1930s, Italian physicists established strong relationships with scientists from other European countries and the United States. The career of Bruno Rossi, a leading personality in the study of cosmic rays and an Italian pioneer of this field of research, provides a prominent example of this kind of international cooperation. Physics underwent major changes during these turbulent years, and the traditional internationalism of physics assumed a more institutionalized character. Against this backdrop, Rossi's early work was crucial in transforming the study of cosmic rays into a branch of modern physics. His friendly relationships with eminent scientists--notably Enrico Fermi, Walther Bothe, Werner Heisenberg, Hans Bethe, and Homi Bhabha--were instrumental both for the exchange of knowledge about experimental practices and theoretical discussions, and for attracting the attention of physicists such as Arthur Compton, Louis Leprince-Ringuet, Pierre Auger and Patrick Blackett to the problem of cosmic rays. Relying on material from different archives in Europe and the United States, this case study aims to provide a glimpse of the intersection between national and international dimensions during the 1930s, at a time when the study of cosmic rays was still very much in its infancy, strongly interlaced with nuclear physics, and full of uncertain, contradictory, and puzzling results. Nevertheless, as a source of high-energy particles it became a proving ground for testing the validity of the laws of quantum electrodynamics, and made a fundamental contribution to the origins of particle physics.

    Highlights, trends, and consensus from the 63 papers submitted to the Scientific Developments theme of the Third International Symposium on Flood Defence (ISFD) are presented. Realizing that absolute protection against flooding can never be guaranteed, trends in flood management have shifted: (1) from flood protection to flood-risk management, (2) from reinforcing structural protection to lowering flood levels, and (3) to sustainable management through integrated problem solving. Improved understanding of watershed responses, climate changes, applications of GIS and remote-sensing technologies, and advanced analytical tools appeared to be the driving forces for renewing flood-risk management strategies. Technical competence in integrating analytical tools to form the basin wide management systems are demonstrated by several large, transnation models. However, analyses from social-economic-environmental points of view are found lag in general. ?? 2006 Taylor & Francis Group.

    Information technologies have found their application in virtually every branch of health care. In recent years they have demonstrated their potential in the development of online library, where scientists and researchers can share their latest findings. Academia.edu, ResearchGate, Mendeley, Kudos, with the support of platform GoogleScholar, have indeed increased the visibility of scientific work of one author, and enable a much greater availability of the scientific work to the broader audience. Online libraries have allowed free access to the scientific content to the countries that could not follow the economic costs of getting access to certain scientific bases. Especially great benefit occurred in countries in transition and developing countries. Online libraries have great potential in terms of expanding knowledge, but they also present a major problem for many publishers, because their rights can be violated, which are signed by the author when publishing the paper. In the future it will lead to a major conflict of the author, the editorial board and online database, about the right to scientific content This question certainly represents one of the most pressing issues of publishing, whose future in printed form is already in the past, and the future of the online editions will be a problem of large-scale.

  11. Test Driven Development of Scientific Models

    Clune, Thomas L.

    2012-01-01

    Test-Driven Development (TDD) is a software development process that promises many advantages for developer productivity and has become widely accepted among professional software engineers. As the name suggests, TDD practitioners alternate between writing short automated tests and producing code that passes those tests. Although this overly simplified description will undoubtedly sound prohibitively burdensome to many uninitiated developers, the advent of powerful unit-testing frameworks greatly reduces the effort required to produce and routinely execute suites of tests. By testimony, many developers find TDD to be addicting after only a few days of exposure, and find it unthinkable to return to previous practices. Of course, scientific/technical software differs from other software categories in a number of important respects, but I nonetheless believe that TDD is quite applicable to the development of such software and has the potential to significantly improve programmer productivity and code quality within the scientific community. After a detailed introduction to TDD, I will present the experience within the Software Systems Support Office (SSSO) in applying the technique to various scientific applications. This discussion will emphasize the various direct and indirect benefits as well as some of the difficulties and limitations of the methodology. I will conclude with a brief description of pFUnit, a unit testing framework I co-developed to support test-driven development of parallel Fortran applications.

    1990-01-01

    Evolutionary sequences developed in another paper are used here to investigate the properties of the red giant branch (RGB) phase transition. Results are found for compositions in the range Y(MS) between 0.20 and 0.30 and Z between 0.004 and 0.04. The transition mass M(HeF) increases as either Y(MS) decreases or Z increases. The stellar population transition age t(HeF) is virtually independent of composition and close to 0.6 Gyr. The RGB phase transition occurs almost abruptly over a mass range of only a few tenths of a solar mass or, equivalently, over a time interval of about 0.2 Gyr in the life of a stellar population. During the RGB phase transition the core mass Mc at helium ignition increases very rapidly by about 0.15 solar mass, while the luminosity at the tip of the RGB increases by about one order of magnitude. Absolute minima are found for the values of Mc and the RGB tip luminosity.

  13. Recent Developments in Scientific Research Ballooning

    2007-01-01

    The National Aeronautics and Space Administration (NASA) Balloon Program is committed to meeting the need for extended duration scientific investigations by providing advanced balloon vehicles and support systems. A sea change in ballooning capability occurred with the inauguration of 8 - 20 day flights around Antarctica in the early 1990's. The attainment of 28-31 day flights and a record-breaking 42-day flight in, respectively, two and three circumnavigations of the continent has greatly increased the expectations of the scientific users. A new super-pressure balloon is currently under development for future flights of 60-100 days at any latitude, which would bring another sea change in scientific research ballooning

  14. Branch Development of Five-Year-Old Betula alnoides Plantations in Response to Planting Density

    2018-01-01

    Full Text Available Branch development in the lower part of stem is critical to both early stem growth and wood quality of the most valuable section of tree, and its regulation through planting density has always been greatly concerned. Here the effect of planting density on branch development was examined in a five-year-old plantation of Betula alnoides with six planting densities (625, 833, 1111, 1250, 1667, and 2500 stems per hectare (sph in Guangdong Province, South China. Branch quantity (number, proportion, and density, morphology (diameter, length, and angle, position (height and orientation, and branch status (dead or alive were investigated for 54 dominant or co-dominant trees under six treatments of planting density after the growth of each tree was measured. Factors influencing branch development were also explored by mixed modelling. The results showed that the mean tree heights of 1250 and 1667 sph treatments were higher than those of other planting density treatments. The quantity of live branches decreased with increasing planting density. However, planting density had no significant effect on the number of all branches, and there existed no remarkable difference in branch number and proportion among four orientations. As for branch morphology, only the largest branch diameter had a significantly negative correlation with planting density. In addition, high planting density significantly increased the height of the largest branch within the crown. Mixed effects models indicated that branch diameter, length, and angle were closely correlated with each other, and they were all in positively significant correlation to the branch height at the stem section below six meters. It was concluded that properly increasing planting density will promote natural pruning, improve early branch control, and be beneficial for wood production from the most valuable section of the stem.

    Scientific methods used by the Los Alamos National Laboratory for developing an ultrastable structure for study of silicon-based elementary particle tracking systems are addressed. In particular, the design, analysis, and monitoring of this system are explored. The development methodology was based on a triad of analytical, computational, and experimental techniques. These were used to achieve a significant degree of mechanical stability (alignment accuracy >1 μrad) and yet allow dynamic manipulation of the system. Estimates of system thermal and vibratory stability and component performance are compared with experimental data collected using laser interferometry and accelerometers. 8 refs., 5 figs., 4 tabs

  1. Quantitative Analysis of Axonal Branch Dynamics in the Developing Nervous System.

    Directory of Open Access Journals (Sweden)

    Kelsey Chalmers

    2016-03-01

    Full Text Available Branching is an important mechanism by which axons navigate to their targets during neural development. For instance, in the developing zebrafish retinotectal system, selective branching plays a critical role during both initial pathfinding and subsequent arborisation once the target zone has been reached. Here we show how quantitative methods can help extract new information from time-lapse imaging about the nature of the underlying branch dynamics. First, we introduce Dynamic Time Warping to this domain as a method for automatically matching branches between frames, replacing the effort required for manual matching. Second, we model branch dynamics as a birth-death process, i.e. a special case of a continuous-time Markov process. This reveals that the birth rate for branches from zebrafish retinotectal axons, as they navigate across the tectum, increased over time. We observed no significant change in the death rate for branches over this time period. However, blocking neuronal activity with TTX slightly increased the death rate, without a detectable change in the birth rate. Third, we show how the extraction of these rates allows computational simulations of branch dynamics whose statistics closely match the data. Together these results reveal new aspects of the biology of retinotectal pathfinding, and introduce computational techniques which are applicable to the study of axon branching more generally.

    2014-01-01

    The hyper branched polyurethane acrylate (HBPUA) was prepared by reacting hyper branched polyol polyester (HBP) from palm oil based with diisocyanate and hydroxyl-containing acrylate monomer with the presence of 0.1-2 wt % dibutyltin dilaurate as a catalyst. The reaction was confirmed by several analyses for example determination of hydroxyl value (OHV), acid value (AV), Fourier transform infrared (FTIR) spectroscopy, gel permeation chromatography (GPC) and nuclear magnetic resonance (NMR) spectroscopy analyses. HBPUA required 0.36 J/ cm 2 energy when undergone curing with UV radiation. HBPUA / TMPTA films showed 4B-2H of pencil hardness, gel content of 60-80 %, contact angle θ between 65-74 degree and T g at -15 to -5 degree Celsius. The presence of TMPTA increased degree of cross-linking and pencil hardness. The characteristic of the polymeric material and the thermal stability of UV cured films of HBPUA formulations were determined by differential scanning calorimetry (DSC) and thermogravimetric analyzer (TGA). The thermal decomposition temperature started at 200 degree Celsius with T max at 450 to 455 degree Celsius. (author)

    Miyaguchi, K; Dezaki, J; Yamamoto, K

    1999-01-01

    We have developed CCDs for scientific applications that feature a low readout noise of less than 5 e-rms and low dark current of 10-25 pA/cm sup 2 at room temperature. CCDs with these characteristics will prove extremely useful in applications such as spectroscopic measurement and dental radiography. In addition, a large-area CCD of 2kx4k pixels and 15 mu m square pixel size has recently been completed for optical use in astronomical observations. Applications to X-ray astronomy require the most challenging device performance in terms of deep depletion, high CTE, and focal plane size, among others. An abuttable X-ray CCD, having 1024x1024 pixels and 24 mu m square pixel size, is to be installed in an international space station (ISS). We are now striving to achieve the lowest usable cooling temperature by means of a built-in TEC with limited power consumption. Details on the development status are described in this report. We would also like to present our future plans for a large active area and deep depleti...

    2014-01-01

    Full Text Available The history of scientific development in Algeria, which has not been long, represents a series of continual rises and falls. The Algerian leadership and researchers have been making efforts to create Algeria's national science through protection from the western scientific tradition, which is reminiscent of the colonial period of the country, and at the same time adoption of scientific knowledge and scientific institutions functioning principles from abroad, with no organizational or scientific experience of their own. Since the time the independent Algerian state was established, its scientific development has been inevitably coupled with active support of European countries, especially France, and other western and non-western states. Today the Algerian leadership is highly devoted to the modernization of the national scientific and research potential in strong cooperation with its foreign partners. The article concentrates on examining the present period (the 2000s of the scientific development in Algeria. The main conclusion is that there still is a number of problems - for Algeria until now lacks an integral scientific community with the state preserving its dominating role in science and research activities. Despite these difficulties, the Algerian science has made an outstanding progress. The efficiently built organizational scientific structure, the growing science and technology cooperation with foreign countries as well as the increasing state expenses in science allow to hope for further success of the Algerian scientific development.

  11. Developing a scientific culture through supervision

    Directory of Open Access Journals (Sweden)

    Danie F.M. Strauss

    2012-11-01

    Full Text Available Through effective educational transmission cultural traditions are passed on to subsequent generations. The presence of alternative theoretical views of reality (paradigms in various academic disciplines uprooted the positivistic conviction that genuine science ought to be ‘objective’ and ‘neutral’. The background of this view is found in Renaissance and post-Renaissance philosophy, with its initial points of culmination in the thought of the 18th century philosopher, Immanuel Kant. He safe-guarded autonomous human freedom by restricting scholarship to phenomena (subject to the universal law of causality. The dialectic between nature and freedom gave direction to modern philosophy. Non-reductionist orientations eventually emerged recognising what is irreducible. Although a sound academic culture,operative within supervision to doctoral students, must pay attention to argumentative skills and informal logic, it must at the same time acknowledge the limitations of logic. The principle of sufficient reason refers human thinking beyond logic itself. The supervisor therefore should generate, amongst students, an awareness of the difference between reductionist and non-reductionist ontologies. Doctoral students must also realise that persistent themes and scientific revolutions go hand-in-hand. Some examples of seeing the aspects of reality as modes of explanation are given, before the seven aims of scientific endeavors identified by Stafleu are stipulated. This constitutes another important guideline that ought to be taken into account in supervising post-graduate work. Argumentative skills, scientific communication and the status of facts are discussed before a concluding formulation is given in which the overall argument of the article is summarised.

    The kidneys are exposed to hypoxic conditions during development. Hypoxia-inducible factor (HIF), an important mediator of the response to hypoxia, is believed to have an important role in development. However, the relationship between HIF and branching morphogenesis has not been elucidated clearly. In this study, we examined whether HIF regulates kidney development. We harvested kidneys from day 13 rat embryos (E13Ks) and cultured the organs under normoxic (20% O2/5% CO2) or hypoxic (5% O2/5% CO2) conditions. We evaluated the kidneys based on morphology and gene expression. E13Ks cultured under hypoxic conditions had significantly more ureteric bud (UB) branching than the E13Ks cultured under normoxic conditions. In addition, the mRNA levels of GDNF and GDNF receptor (GFR-α1), increased under hypoxic conditions in E13Ks. When we cultured E13Ks with the HIF-1α inhibitor digoxin or with siRNA targeting HIF-1α under hypoxic conditions, we did not observe increased UB branching. In addition, the expression of GDNF and GFR-α1 was inhibited under hypoxic conditions when the kidneys were treated with siRNA targeting HIF-1α. We also elucidated that hypoxia inhibited UB cell apoptosis and promoted the expression of FGF7 mRNA levels in metanephric mesenchymal (MM) cells in vitro. These findings suggest that hypoxic condition has important roles in inducing branching morphogenesis during kidney development. Hypoxia might mediate branching morphogenesis via not only GDNF/Ret but also FGF signaling pathway. Copyright © 2014 Elsevier Inc. All rights reserved.

    We present the details of a software development methodology that addresses all phases of the software life cycle, yet is well suited for application by small projects with limited resources. The methodology has been developed at the Los Alamos Weapons Neutron Research (WNR) Facility and was utilized during the recent development of the WNR Data Acquisition Command Language. The methodology emphasizes the development and maintenance of comprehensive documentation for all software components. The impact of the methodology upon software quality and programmer productivity is assessed

    Serious scientific games, especially those that include a virtual apprenticeship component, provide players with realistic experiences in science. This article discusses how science games can influence learning about science and the development of science-oriented possible selves through repeated practice in professional play and through social influences (e.g., peer groups). We first review the theory of possible selves (Markus and Nurius 1986) and discuss the potential of serious scientific games for influencing the development of scientific possible selves. As part of our review, we present a forensic game that inspired our work. Next we present a measure of scientific possible selves and assess its reliability and validity with a sample of middle-school students ( N = 374). We conclude by discussing the promise of science games and the development of scientific possible selves on both the individual and group levels as a means of inspiring STEM careers among adolescents.

  18. Epistemological pluralism and scientific development: an argument against authoritative nosologies.

    Markon, Kristian E

    2013-10-01

    The author examines the influence of authoritative nosological systems--those developed by an authoritative body or organization (e.g., the DSM, ICD, RDoC)--on the development of scientific theory and research. Although there has been extensive discussion of how such systems should be organized, and of the historical role of such systems, little focus has been placed on whether these systems impede or facilitate scientific progress. The author reviews the nature and role of constructs in scientific theory and the role of authoritative taxonomy in science. He presents an argument that, although authoritative classification systems clearly have value for nonscientific purposes, or for specific scientific purposes, the systems themselves, at least as they have been constructed thus far, likely impede scientific development by constraining competitive discourse. Implications and recommendations are discussed.

    Fatty acids (FA) and FA-derived metabolites have long been implicated in the development of insulin resistance and type 2 diabetes. Surprisingly, application of metabolomics technologies has revealed that branched-chain amino acids (BCAA) and related metabolites are more strongly associated with insulin resistance than many common lipid species. Moreover, the BCAA-related signature is predictive of incident diabetes and intervention outcomes, and uniquely responsive to therapeutic interventio...

    In this study we establish a process to predict hardening behavior considering the Branchings effect for zircaloy-4 sheets. When a metal is compressed after tension in forming, the yield strength decreases. For this reason, the Branchings effect should be considered in FE simulations of spring-back. We suggested a suitable specimen size and a method for determining the optimum tightening torque for simple shear tests. Shear stress-strain curves are obtained for five materials. We developed a method to convert the shear load-displacement curve to the effective stress-strain curve with Fea. We simulated the simple shear forward/reverse test using the combined isotropic/kinematic hardening model. We also investigated the change of the load-displacement curve by varying the hardening coefficients. We determined the hardening coefficients so that they follow the hardening behavior of zircaloy-4 in experiments

    We have redesigned a tried-and-true laboratory exercise into an inquiry-based team activity exploring microbial growth control, and implemented this activity as the basis for preparing a scientific poster in a large, multi-section laboratory course. Spanning most of the semester, this project culminates in a poster presentation of data generated from a student-designed experiment. Students use and apply the scientific method and improve written and verbal communication skills. The guided inquiry format of this exercise provides the opportunity for student collaboration through cooperative learning. For each learning objective, a percentage score was tabulated (learning objective score = points awarded/total possible points). A score of 80% was our benchmark for achieving each objective. At least 76% of the student groups participating in this project over two semesters achieved each learning goal. Student perceptions of the project were evaluated using a survey. Nearly 90% of participating students felt they had learned a great deal in the areas of formulating a hypothesis, experimental design, and collecting and analyzing data; 72% of students felt this project had improved their scientific writing skills. In a separate survey, 84% of students who responded felt that peer review was valuable in improving their final poster submission. We designed this inquiry-based poster project to improve student scientific communication skills. This exercise is appropriate for any microbiology laboratory course whose learning outcomes include the development of scientific inquiry and literacy. PMID:29904518

    The flowers of major cereals are arranged on reproductive branches known as spikelets, which group together to form an inflorescence. Diversity for inflorescence architecture has been exploited during domestication to increase crop yields, and genetic variation for this trait has potential to further boost grain production. Multiple genes that regulate inflorescence architecture have been identified by studying alleles that modify gene activity or dosage; however, little is known in wheat. Here, we show TEOSINTE BRANCHED1 (TB1) regulates inflorescence architecture in bread wheat (Triticum aestivum) by investigating lines that display a form of inflorescence branching known as “paired spikelets.” We show that TB1 interacts with FLOWERING LOCUS T1 and that increased dosage of TB1 alters inflorescence architecture and growth rate in a process that includes reduced expression of meristem identity genes, with allelic diversity for TB1 found to associate genetically with paired spikelet development in modern cultivars. We propose TB1 coordinates formation of axillary spikelets during the vegetative to floral transition and that alleles known to modify dosage or function of TB1 could help increase wheat yields.

    This paper deals with a diagnostic and monitoring system for assessing the integrity of pipe branches, during the operation of the nuclear power plant. This system have been developed under the concept of ''easy to use without any sophisticated analysis'' and ''portable''. The accuracy of the diagnosis is based on the model optimization subsystem, which automatically modifies the numerical vibration model so as to fit its natural frequency to the actual natural frequency. The information obtained by this system may be reflected to a maintenance program of the plant to assure more reliable operation of the plant. (orig.)

    Dowsett, Sherie A; Van Campen, Luann E; Bednar, Lisa A

    2010-06-01

    The scientific publishing practices of the pharmaceutical industry have been heavily criticized in recent years due to the inherent conflict of interest that arises when a pharmaceutical company publishes findings around its own drugs. Eli Lilly and Company ('Lilly') strives for transparency in its day-to-day activities, and, here, shares its principles, policies and practices on publishing "Lilly-sponsored" research. A conflict of interest does not necessarily equate to biased presentation of research findings, and operating a successful, for-profit business and maintaining a focus on improving the health of patients are not mutually exclusive goals. There is, however, potential for bias, and it is incumbent upon a for-profit to develop publication principles, policies and practices to address this. To this end, Lilly's Principles of Medical Research states that 'Lilly discloses publicly all medical research results that are important to patients, healthcare providers or payers--whether favorable or unfavorable to a Lilly product--in an accurate, objective, and balanced manner ...' The preparation of publications of Lilly-sponsored research involves close collaboration between external (i.e., academic or otherwise non-industry employees) and Lilly scientific researchers (including scientific writers), with both serving as authors. Lilly does not support 'ghost' or 'guest' authorship. Authorship is not just recognition of contribution but also public acknowledgement of responsibility for content, and all authors are expected to take an active role in developing the manuscript in line with the International Committee of Medical Journal Editors-based authorship requirements. This is agreed to by authors before the manuscript is started. Lilly provides external authors with access to the trial data for manuscript development. Lilly does not pay external authors for their involvement in manuscript development. Scientific writers at Lilly, often with advanced scientific

    Scientific Approach is a learning process, designed to make the students actively construct their own knowledge through stages of scientific method. The scientific approach in learning process can be done by using learning modules. One of the learning model is discovery based learning. Discovery learning is a learning model for the valuable things in learning through various activities, such as observation, experience, and reasoning. In fact, the students’ activity to construct their own knowledge were not optimal. It’s because the available learning modules were not in line with the scientific approach. The purpose of this study was to develop a scientific approach discovery based learning module on Acid Based, also on electrolyte and non-electrolyte solution. The developing process of this chemistry modules use the Plomp Model with three main stages. The stages are preliminary research, prototyping stage, and the assessment stage. The subject of this research was the 10th and 11th Grade of Senior High School students (SMAN 2 Padang). Validation were tested by the experts of Chemistry lecturers and teachers. Practicality of these modules had been tested through questionnaire. The effectiveness had been tested through experimental procedure by comparing student achievement between experiment and control groups. Based on the findings, it can be concluded that the developed scientific approach discovery based learning module significantly improve the students’ learning in Acid-based and Electrolyte solution. The result of the data analysis indicated that the chemistry module was valid in content, construct, and presentation. Chemistry module also has a good practicality level and also accordance with the available time. This chemistry module was also effective, because it can help the students to understand the content of the learning material. That’s proved by the result of learning student. Based on the result can conclude that chemistry module based on

    Full Text Available With significant improvements in living standards in China and the aging population that accompanies these improvements, the market demand for high-quality orthopaedic biomaterials for clinical applications is tremendous and growing rapidly. There are major efforts to promote cooperation between different scientific institutes with complementary strengths for the further development of the biomaterial industry in China to achieve the technological level of developed countries. An excellent example is that the Ministry of Science and Technology of the People's Republic of China (MOST; Beijing, China established the Chinese National Engineering Research Centres (CNERCs, which serve as a major initiative in driving basic and applied technological research and development (R&D in mainland China. To create a win-win situation with Hong Kong, the MOST and the Hong Kong Innovation and Technology Commission are jointly establishing the Hong Kong Branch of the CNERCs. Through an amicable arrangement, the Chinese University of Hong Kong (CUHK; Shatin, Hong Kong and the Chinese National Engineering Research Centre for Biomaterials (i.e., Main Centre in Chengdu, People's Republic of China have decided to apply to establish the Hong Kong Branch of the CNERC for Biomaterials at the CUHK. The effort in establishing the Hong Kong Branch of Biomaterials seeks to promote further collaboration with the Main Centre with the goals of promoting synergy and a win-win cooperation between mainland China and Hong Kong in scientific research, talent cultivation, clinically driven novel biomaterials product design, and preclinical and clinical testing. It will thus become a model for the successful collaboration between the Hong Kong research institutions and the mainland CNERCs in the area of biomaterials. Such initiatives will facilitate close collaboration in translational medicine associated with biomaterial development and application.

    This study is a component of a four-year investigation of MS PHD'S Professional Development Program's virtual community through the lenses of underrepresented minority students in Earth system science and engineering fields. In this presentation, the development, assessment and projected utilization of the ongoing study will be discussed. The overall goal of this study is to examine the effectiveness of virtual team building methods and understand how the development of a communal cyberinfrastructure acts as an integral part of the emergence of a Scientific Renaissance. The exemplar, Minorities Striving and Pursuing Higher Degrees of Success in Earth System Science (MS PHD'S), provides professional development experiences to facilitate the advancement of students of color achieving outstanding Earth system careers. Undergraduate and graduate students are supported through access to scientific conferences, mentorship and virtual community building. Framed by critical theory, this ethnographic exploration uses a mixed methods research design to record, observe, and analyze both the processes and products of the website, listserv and synchronous web-based dialogue. First, key findings of the formative evaluation and annual reports of the successfully implemented 2003 MS PHD'S Pilot Project are presented. These findings inform future evaluations of the use of technological resources and illustrate how this public space provides peer support and enriched research opportunities. Quantitative methods such as statistical analysis, academic and professional tracking and evaluative tools for scientific content and competency are complimented by qualitative methods that include observations, heuristic case studies and focus group interviews. The findings of this ongoing investigation will provide insight on how national organizations, higher education practitioners, community-based support systems and underrepresented minorities in the sciences promote diversity by developing

    To help students develop the scientific abilities desired in the 21st century workplace, four different types of student design tasks—observation, verification, application, and investigation experiments—have been developed and implemented in our calculus-based introductory courses. Students working in small groups are engaged in designing and conducting their own experiments to observe some physical phenomena, test a physical principle, build a real-life device, solve a complex problem, or conduct an open-inquiry investigation. A preliminary study has shown that, probed by a performance-based task, the identified scientific abilities are more explicitly demonstrated by design-lab students than non-design lab students. In this paper, detailed examples of the design tasks and assessment results will be reported.

    The purposes of this study were to investigate students’ learning progression on reading activity, science concept comprehension and how they imply it in scientific communication in the classroom. Fifty-nine biology education students participated in this study. This classroom research was developed to portray students’ reading activity, factors affecting reading comprehension, and the development of reading motivation. Qualitative analysis was used to describe the whole activities, involve the instruction, process and the product of reading activity. The result concluded that each student has their own way in interpreting the information from scientific text, but generally, they can filter and apply it in their argument as a part of reasoning and evidence. The findings can be used to direct reading activity to the goal of inquiry in order to support the nature of reading as evidence.

    Quantifying the impact of anthropogenic development on local populations is important for conservation biology and wildlife management. However, these local populations are often subject to demographic stochasticity because of their small population size. Traditional modeling efforts such as population projection matrices do not consider this source of variation whereas individual-based models, which include demographic stochasticity, are computationally intense and lack analytical tractability. One compromise between approaches is branching process models because they accommodate demographic stochasticity and are easily calculated. These models are known within some sub-fields of probability and mathematical ecology but are not often applied in conservation biology and applied ecology. We applied branching process models to quantitatively compare and prioritize species locally vulnerable to the development of wind energy facilities. Specifically, we examined species vulnerability using branching process models for four representative species: A cave bat (a long-lived, low fecundity species), a tree bat (short-lived, moderate fecundity species), a grassland songbird (a short-lived, high fecundity species), and an eagle (a long-lived, slow maturation species). Wind turbine-induced mortality has been observed for all of these species types, raising conservation concerns. We simulated different mortality rates from wind farms while calculating local extinction probabilities. The longer-lived species types (e.g., cave bats and eagles) had much more pronounced transitions from low extinction risk to high extinction risk than short-lived species types (e.g., tree bats and grassland songbirds). High-offspring-producing species types had a much greater variability in baseline risk of extinction than the lower-offspring-producing species types. Long-lived species types may appear stable until a critical level of incidental mortality occurs. After this threshold, the risk of

    The quality by design (QbD) paradigm guides the pharmaceutical industry towards improved understanding of products and processes, and at the same time facilitates a high degree of manufacturing and regulatory flexibility throughout the establishment of the design space. This review article presents scientific, statistical and regulatory considerations in design space development. All key development milestones, starting with planning, selection of factors, experimental execution, data analysis, model development and assessment, verification, and validation, and ending with design space submission, are presented and discussed. The focus is especially on frequently ignored topics, like management of factors and CQAs that will not be included in experimental design, evaluation of risk of failure on design space edges, or modeling scale-up strategy. Moreover, development of a design space that is independent of manufacturing scale is proposed as the preferred approach.

    1994-01-01

    Iodine-123-labeled fatty acids represent unique metabolic probes for correlation of energy substrate metabolism with regional myocardial viability. Interest in the use of these agents results from differences which are often observed in various types of heart disease between regional myocardial fatty acid uptake patterns and flow tracer distribution. Although the physiological basis is not completely understood, differences between regional fatty acid and flow tracer distribution may reflect alterations in important parameters of metabolism which can be useful for patient management or therapeutic strategy decision making. The iodine-123-labeled 15-(p-iodophenyl)-3-R,S-methylpentadecanoic acid (BMIPP) fatty acid analogue was developed at the Oak Ridge National Laboratory and was recently introduced as ''Cardiodine trademark'' in 1993 by Nihon Medi-Physics for commercial distribution in Japan. Iodine-123-BMPP is also being used in clinical studies on an institutional approval basis at several institutions in Europe and the US. This paper describes the development of the concept of fatty acid ''metabolic trapping'' of methyl-branched fatty acids and their use for single photon emission computerized tomographic cardiac imaging

    The public in general does not necessarily have enough knowledge for the reasonable decision making in the application of scientific and technological development even in the ear of the Information Society. However strongly the necessity of the consensus in the scientific policy like nuclear R and D is required, it is impossible to attain the goal, unless the scientific literacy of the general public is. In order to improve it the role of the scientific museum as a social educational facility is very important. In this respect, there still remains vast room to improve in the Japanese museum system and its activities. The concept of the 'Central Scientific and Technological Museum-Institute', which also operates very small-sized reactor for the educational use, is developed in this paper. (author)

    A scientific visit on Crystalline Rock Repository Development was held in the Czech Republic on September 24-27, 2012. The visit was hosted by the Czech Radioactive Waste Repository Authority (RAWRA), co-hosted by Sandia National Laboratories (SNL), and supported by the International Atomic Energy Agency (IAEA). The purpose of the visit was to promote technical information exchange between participants from countries engaged in the investigation and exploration of crystalline rock for the eventual construction of nuclear waste repositories. The visit was designed especially for participants of countries that have recently commenced (or recommenced) national repository programmes in crystalline host rock formations. Discussion topics included repository programme development, site screening and selection, site characterization, disposal concepts in crystalline host rock, regulatory frameworks, and safety assessment methodology. Interest was surveyed in establishing a %E2%80%9Cclub,%E2%80%9D the mission of which would be to identify and address the various technical challenges that confront the disposal of radioactive waste in crystalline rock environments. The idea of a second scientific visit to be held one year later in another host country received popular support. The visit concluded with a trip to the countryside south of Prague where participants were treated to a tour of the laboratory and underground facilities of the Josef Regional Underground Research Centre.

    The available literature shows us that "Druztvo ljeciteljah u Zagrebus (the Society of Healers in Zagreb) was founded as far back as the year 1845 by a total of thirteen members. This data allows us to follow the role of doctors and health workers in Zagreb through their everyday profession, research, organizational and social work as well as management through a period of over one hundred to seventy years. The Branch Zagreb was active before the official establishment of subsidiaries of CMA which is evident from the minutes of the regular annual assembly of the Croatian Medical Association on 21 March 1948. Until the end of 1956, there was no clear division of labor, functions and competencies between the Branch and the Main Board. Their actions were instead consolidated and the Branch operated within and under the name of Croatian Medical Association. In that year the Branch became independent. The Branch Zagreb is the largest and one of the most active branches of the Croatian Medical Association. At the moment, the Branch brings together 3621 members, regular members--doctors of medicine (2497), doctors of dental medicine (384), retired physicians (710), and associate members (30 specialists with higher education who are not doctors). The Branch is especially accomplished in its activities in the area of professional development of its members and therefore organizes a series of scientific conferences in the framework of continuous education of physicians, allowing its members to acquire necessary points for the extension of their operating license. The choir "Zagrebacki lijecnici pjevaci" (Zagreb Physicians' Choir) of the Croatian Medical Music Society of the CMA and its activities are inseparable from the Branch Zagreb. The Branch is firmly linked to the parent body, the CMA, and thus has a visible impact on the strategy and the activities of the Association as a whole. Most professional societies of the CMA have their headquarters in Zagreb and this is

    Corticospinal axons innervate their midbrain, hindbrain, and spinal targets by extending collateral branches interstitially along their length. To establish that the axon shaft rather than the axonal growth cone is responsible for target recognition in this system, and to characterize the dynamics of interstitial branch formation, we have studied this process in an in vivo-like setting using slice cultures from neonatal mice containing the entire pathway of corticospinal axons. Corticospinal axons labeled with the dye 1,1'-dioctodecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate (or Dil) were imaged using time-lapse video microscopy of their pathway overlying the basilar pons, their major hindbrain target. The axon shaft millimeters behind the growth cone exhibits several dynamic behaviors, including the de novo formation of varicosities and filopodia-like extensions, and a behavior that we term "pulsation," which is characterized by a variable thickening and thining of short segments of the axon. An individual axon can have multiple sites of branching activity, with many of the branches being transient. These dynamic behaviors occur along the portion of the axon shaft overlying the basilar pons, but not just caudal to it. Once the collaterals extend into the pontine neuropil, they branch further in the neuropil, while the parent axon becomes quiescent. Thus, the branching activity is spatially restricted to specific portions of the axon, as well as temporally restricted to a relatively brief time window. These findings provide definitive evidence that collateral branches form de novo along corticospinal axons and establish that the process of target recognition in this system is a property of the axon shaft rather than the leading growth cone.

    Full Text Available In recent decades, research has growth Increasingly in Iran and, consequently, the country has risen dramatically in world rankings, based on the number of scientific documents. Meanwhile, research policy makers of different societies have concentrated, more and more, on "the effectiveness of researches" and today, their main concern is to ensure that researches are truly contributing to achieve development goals. The issue of "use of research to improve society" has also been emphasized by Iran high-ranking managers and consultants in superior governmental documents, implying their agreement on the importance and necessity of it. Experts' view about the necessity for science to play a fundamental role in the process of society improvement, research impact assessment specialists' models in which they directly emphasize on "promotion of development scale" as the research final expected effect, and the proven high correlation between scientific progress and economic development of societies, create a reasonable expectation that as a consequent of "remarkable progress in research", Iran has experienced a tangible improvement in other aspects and this improvement has been reflected in development indicators. This expectation leads to a question which has been the main reason for this study to be implemented. The purpose of this study is to examine the effectiveness of Iran increasingly research growth in recent three decades on the country development. The study uses a Descriptive-Analytical method and valid secondary data have been the base of analyses. At first, the reliable development indicators for which data were available for a number of countries in an appropriate timeframe were selected. Next, the rank of Iran determined in any indicator among 215 countries (based on the number of countries in World Bank Web site. Then, the trend of Iran's research position was compared with the trend of Iran's position in terms of each development

    Full Text Available The normal human adult kidney contains between 300,000 and 1 million nephrons (the functional units of the kidney. Nephrons develop at the tips of the branching ureteric duct, and therefore ureteric duct branching morphogenesis is critical for normal kidney development. Current methods for analysing ureteric branching are mostly qualitative and those quantitative methods that do exist do not account for the 3- dimensional (3D shape of the ureteric "tree". We have developed a method for measuring the total length of the ureteric tree in 3D. This method is described and preliminary data are presented. The algorithm allows for performing a semi-automatic segmentation of a set of grey level confocal images and an automatic skeletonisation of the resulting binary object. Measurements of length are automatically obtained, and numbers of branch points are manually counted. The final representation can be reconstructed by means of 3D volume rendering software, providing a fully rotating 3D perspective of the skeletonised tree, making it possible to identify and accurately measure branch lengths. Preliminary data shows the total length estimates obtained with the technique to be highly reproducible. Repeat estimates of total tree length vary by just 1-2%. We will now use this technique to further define the growth of the ureteric tree in vitro, under both normal culture conditions, and in the presence of various levels of specific molecules suspected of regulating ureteric growth. The data obtained will provide fundamental information on the development of renal architecture, as well as the regulation of nephron number.

    Human discovery of pharmacologically active substances is arguably the oldest of the biomedical sciences with origins >3500 years ago. Since ancient times, four major transformations have dramatically impacted pharmaceutical development, each driven by advances in scientific knowledge, technology, and/or regulation: (1) anesthesia, analgesia, and antisepsis; (2) medicinal chemistry; (3) regulatory toxicology; and (4) targeted drug discovery. Animal experimentation in pharmaceutical development is a modern phenomenon dating from the 20th century and enabling several of the four transformations. While each transformation resulted in more effective and/or safer pharmaceuticals, overall attrition, cycle time, cost, numbers of animals used, and low probability of success for new products remain concerns, and pharmaceutical development remains a very high risk business proposition. In this manuscript we review pharmaceutical development since ancient times, describe its coevolution with animal experimentation, and attempt to predict the characteristics of future transformations. © The Author 2016.

    Autosomal dominant polycystic kidney disease (ADPKD) is characterized by the progressive development of kidney and liver cysts. The mammalian target of rapamycin (mTOR) cascade is one of the important pathways regulating cyst growth in ADPKD. Branched-chain amino acids (BCAAs), including leucine, play a crucial role to activate mTOR pathway. Therefore, we administered BCAA dissolved in the drinking water to Pkd1 flox/flox :Mx1-Cre (cystic) mice from four to 22 weeks of age after polyinosinic-polycytidylic acid-induced conditional Pkd1 knockout at two weeks of age. The BCAA group showed significantly greater kidney/body weight ratio and higher cystic index in both the kidney and liver compared to the placebo-treated mice. We found that the L-type amino acid transporter 1 that facilitates BCAA entry into cells is strongly expressed in cells lining the cysts. We also found increased cyst-lining cell proliferation and upregulation of mTOR and mitogen-activated protein kinase/extracellular signal-regulated kinase (MAPK/ERK) pathways in the BCAA group. In vitro, we cultured renal epithelial cell lines from Pkd1 null mice with or without leucine. Leucine was found to stimulate cell proliferation, as well as activate mTOR and MAPK/ERK pathways in these cells. Thus, BCAA accelerated disease progression by mTOR and MAPK/ERK pathways. Hence, BCAA may be harmful to patients with ADPKD. Copyright © 2017 International Society of Nephrology. Published by Elsevier Inc. All rights reserved.

    The problem of sharing data among scientific simulation models is a difficult and persistent one. Computational scientists employ an enormous variety of discrete approximations in modeling physical processes on computers. Problems occur when models based on different representations are required to exchange data with one another, or with some other software package. Within the DOE`s Accelerated Strategic Computing Initiative (ASCI), a cross-disciplinary group called the Data Models and Formats (DMF) group, has been working to develop a common data model. The current model is comprised of several layers of increasing semantic complexity. One of these layers is an abstract model based on set theory and topology called the fiber bundle kernel (FBK). This layer provides the flexibility needed to describe a wide range of mesh-approximated functions as well as other entities. This paper briefly describes the ASCI common data model, its mathematical basis, and ASCI prototype development. These prototypes include an object-oriented data management library developed at Los Alamos called the Common Data Model Library or CDMlib, the Vector Bundle API from the Lawrence Livermore Laboratory, and the DMF API from Sandia National Laboratory.

    Document available in extended abstract form only. The Research and Development Division must manage, secure and reliable manner, a large number of data from scientific disciplines and diverse means of acquisition (observations, measurements, experiments, etc.). This management is particularly important for the Underground research Laboratory, the source of many recording continuous measurements. Thus, from its conception, Andra has implemented two management tools of scientific information, the 'Acquisition System and Data Management' [SAGD] and GEO database with its associated applications. Beyond its own needs, Andra wants to share its achievements with the scientific community, and it therefore provides the data stored in its databases or samples of rock or water when they are available. Acquisition and Data Management (SAGD) This system manages data from sensors installed at several sites. Some sites are on the surface (piezometric, atmospheric and environmental stations), the other are in the Underground Research Laboratory. This system also incorporates data from experiments in which Andra participates in Mont Terri Laboratory in Switzerland. S.A.G.D fulfils these objectives by: - Make available in real time on a single system, with scientists from Andra but also different partners or providers who need it, all experimental data from measurement points - Displaying the recorded data on temporal windows and specific time step, - Allowing remote control of the experimentations, - Ensuring the traceability of all recorded information, - Ensuring data storage in a data base. S.A.G.D has been deployed in the first experimental drift at -445 m in November 2004. It was subsequently extended to the underground Mont Terri laboratory in Switzerland in 2005, to the entire surface logging network of the Meuse / Haute-Marne Center in 2008 and to the environmental network in 2011. All information is acquired, stored and manage by a software called Geoscope. This software

    We investigate the statistical properties of a special branching point process. The initial process is assumed to be a homogeneous Poisson point process (HPP). The initiating events at each branching stage are carried forward to the following stage. In addition, each initiating event independently contributes a nonstationary Poisson point process (whose rate is a specified function) located at that point. The additional contributions from all points of a given stage constitute a doubly stochastic Poisson point process (DSPP) whose rate is a filtered version of the initiating point process at that stage. The process studied is a generalization of a Poisson branching process in which random time delays are permitted in the generation of events. Particular attention is given to the limit in which the number of branching stages is infinite while the average number of added events per event of the previous stage is infinitesimal. In the special case when the branching is instantaneous this limit of continuous branching corresponds to the well-known Yule--Furry process with an initial Poisson population. The Poisson branching point process provides a useful description for many problems in various scientific disciplines, such as the behavior of electron multipliers, neutron chain reactions, and cosmic ray showers

  1. African Scientific Network: A model to enhance scientific research in developing countries

    Africa has over 350 higher education institutions with a variety of experiences and priorities. The primary objectives of these institutions are to produce white-collar workers, teachers, and the work force for mining, textiles, and agricultural industries. The state of higher education and scientific research in Africa have been discussed in several conferences. The proposals that are generated by these conferences advocate structural changes in higher education, North-South institutional linkages, mobilization of the African Diaspora and funding. We propose a model African Scientific Network that would facilitate and enhance international scientific partnerships between African scientists and their counterparts elsewhere. A recent article by James Lamout (Financial Times, August 2, 2001) indicates that emigration from South Africa alone costs $8.9 billion in lost human resources. The article also stated that every year 23,000 graduates leave Africa for opportunities overseas, mainly in Europe, leaving only 20,000 scientists and engineers serving over 600 million people. The International Organization for Migration states that the brain drain of highly skilled professionals from Africa is making economic growth and poverty alleviation impossible across the continent. In our model we will focus on a possible networking mechanism where the African Diaspora will play a major role in addressing the financial and human resources needs of higher education in Africa

    Meniscus tears are one of the most commonly occurring injuries of the knee joint. Current meniscus repair techniques are challenging and do not bring fully satisfactory results. Tissue adhesives are a promising alternative, since they are easy to apply and cause minimal tissue trauma. In this study, a series of amphiphilic copolymers based on polyethylene glycol, trimethylene carbonate and citric acid were synthesized and subsequently end-functionalized with hexamethylene diisocyanate to form reactive adhesive materials. The shear adhesive strength of the networks to bovine meniscus tissue measured in a lap-shear adhesion test ranged between 20 and 80 kPa, which was better than for fibrin glue (10 kPa). The elastic modulus of the networks depended on composition and was in the same range as that of human meniscus. Cell compatibility was assessed using Alamar Blue staining after incubation of the bovine meniscus cells with different concentrations of the glues for 7 days. Cell viability was not affected after adding up to 3mg of the adhesive/mL of medium. The proposed materials are suitable candidates to be used as resorbable tissue adhesives for meniscus repair. They have excellent mechanical and adhesive properties that can be adjusted by varying the composition of the copolymers. Meniscal tears often occur and current treatment strategies do not bring fully satisfactory results. Use of biodegradable tissue adhesives would be an interesting option, but currently available adhesives are not suited due to toxicity or poor mechanical properties. Here, we describe the development of novel biodegradable, hyper-branched, adhesive copolymers. These adhesives cure upon contact with water forming flexible networks. Their adhesion to bovine meniscus tissue was significantly better than that of clinically used fibrin glue. The tensile properties of the cured networks were in the same range of values of the human meniscus. When physiologically relevant amounts were added to

    2014-01-01

    Over the last two decades, nanotechnology has not only grown considerably but also evolved in its use of scientific terminology. This paper examines the growth in nano-prefixed terms in a corpus of nanotechnology scholarly publications over a 21-year time period. The percentage of publications using a nano-prefixed term has increased from nanotechnology papers oriented toward biomedical and clinical medicine applications has risen from just over 5 % to more than 11 %. While these results cannot fully distinguish between the use of nano-prefixed terms in response to broader policy or societal influences, they do suggest that there are intellectual and scientific underpinnings to the growth of a collectively shared vocabulary. We consider whether our findings signify the maturation of a scientific field and the extent to which this denotes the emergence of a shared scientific understanding regarding nanotechnology.

  10. Relational grounding facilitates development of scientifically useful multiscale models

    Directory of Open Access Journals (Sweden)

    2011-09-01

    Full Text Available Abstract We review grounding issues that influence the scientific usefulness of any biomedical multiscale model (MSM. Groundings are the collection of units, dimensions, and/or objects to which a variable or model constituent refers. To date, models that primarily use continuous mathematics rely heavily on absolute grounding, whereas those that primarily use discrete software paradigms (e.g., object-oriented, agent-based, actor typically employ relational grounding. We review grounding issues and identify strategies to address them. We maintain that grounding issues should be addressed at the start of any MSM project and should be reevaluated throughout the model development process. We make the following points. Grounding decisions influence model flexibility, adaptability, and thus reusability. Grounding choices should be influenced by measures, uncertainty, system information, and the nature of available validation data. Absolute grounding complicates the process of combining models to form larger models unless all are grounded absolutely. Relational grounding facilitates referent knowledge embodiment within computational mechanisms but requires separate model-to-referent mappings. Absolute grounding can simplify integration by forcing common units and, hence, a common integration target, but context change may require model reengineering. Relational grounding enables synthesis of large, composite (multi-module models that can be robust to context changes. Because biological components have varying degrees of autonomy, corresponding components in MSMs need to do the same. Relational grounding facilitates achieving such autonomy. Biomimetic analogues designed to facilitate translational research and development must have long lifecycles. Exploring mechanisms of normal-to-disease transition requires model components that are grounded relationally. Multi-paradigm modeling requires both hyperspatial and relational grounding.

    Full Text Available Reputation management deals with establishing, maintaining and strengthening a positive reputation for an object in order to build trust, commitment and lasting relationships. Positive reputation is considered a major intangible asset of companies as it contributes to their value creation. Reputation and reputation management, therefore, are well-established perspectives in marketing theory. This paper examines reputation in matters of scientific organisations. Drawing on conventional (commercial marketing models of reputation management and derived characteristics of scientific organisations, a modified framework is deduced, named the Scientific Organisations Reputation Model (SORM. As this model widely fits the specific requirements of this type of organisation it will be useful for the complex task of marketing scientific organisations. Using the SORM framework, scientific organisations will be able to understand the formation of their own reputation in a more comprehensive way and will be able to improve their reputation-relevant management processes. The framework is exemplified and examined more closely using the case of DHBW, the unique German cooperate state university as the interplay of stakeholder patterns and the integration of multi-level marketing activities are carved out and main effects on reputation are demonstrated.

    The accelerated development of digital libraries and archives, in tandem with efficient search engines and the computational ability to retrieve and parse massive amounts of information, are making it possible to quantify the time evolution of scientific literatures. These data are but one piece of the tangible recorded evidence of the processes whereby scientists create and exchange information in their journeys towards the generation of knowledge. As such, these tools provide a proxy with which to study our ability to innovate. Innovation has often been linked with prosperity and growth and, consequently, trying to understand what drives scientific innovation is of extreme interest. Identifying sets of population characteristics, factors, and mechanisms that enable scientific communities to remain at the cutting edge, accelerate their growth, or increase their ability to re-organize around new themes or research topics is therefore of special significance. Yet generating a quantitative understanding of the factors that make scientific fields arise and/or become more or less productive is still in its infancy. This is precisely the type of knowledge most needed for promoting and sustaining innovation. Ideally, the efficient and strategic allocation of resources on the part of funding agencies and corporations would be driven primarily by knowledge of this type. Early steps have been taken toward such a quantitative understanding of scientific innovation. Some have focused on characterizing the broad properties of relevant time series, such as numbers of publications and authors in a given field. Others have focused on the structure and evolution of networks of coauthorship and citation. Together these types of studies provide much needed statistical analyses of the structure and evolution of scientific communities. Despite these efforts, however, crucial elements of prediction have remained elusive. Building on many of these earlier insights, we provide here a

  17. Developing Scientific Reasoning Through Drawing Cross-Sections

    Science.gov (United States)

    Hannula, K. A.

    2012-12-01

    Cross-sections and 3D models of subsurface geology are typically based on incomplete information (whether surface geologic mapping, well logs, or geophysical data). Creating and evaluating those models requires spatial and quantitative thinking skills (including penetrative thinking, understanding of horizontality, mental rotation and animation, and scaling). However, evaluating the reasonableness of a cross-section or 3D structural model also requires consideration of multiple possible geometries and geologic histories. Teaching students to create good models requires application of the scientific methods of the geosciences (such as evaluation of multiple hypotheses and combining evidence from multiple techniques). Teaching these critical thinking skills, especially combined with teaching spatial thinking skills, is challenging. My Structural Geology and Advanced Structural Geology courses have taken two different approaches to developing both the abilities to visualize and to test multiple models. In the final project in Structural Geology (a 3rd year course with a pre-requisite sophomore mapping course), students create a viable cross-section across part of the Wyoming thrust belt by hand, based on a published 1:62,500 geologic map. The cross-section must meet a number of geometric criteria (such as the template constraint), but is not required to balance. Each student tries many potential geometries while trying to find a viable solution. In most cases, the students don't visualize the implications of the geometries that they try, but have to draw them and then erase their work if it does not meet the criteria for validity. The Advanced Structural Geology course used Midland Valley's Move suite to test the cross-sections that they made in Structural Geology, mostly using the flexural slip unfolding algorithm and testing whether the resulting line lengths balanced. In both exercises, students seemed more confident in the quality of their cross-sections when the

    2015-01-01

    Scientific inquiry represents a multifaceted approach to explore and understand the natural world. Training students in the principles of scientific inquiry can help promote the scientific learning process as well as help students enhance their understanding of scientific research. Here, we report on the development and implementation of a learning module that introduces astrobiology students to the concepts of creative and scientific inquiry, as well as provide practical exercises to build critical thinking skills. The module contained three distinct components: (1) a creative inquiry activity designed to introduce concepts regarding the role of creativity in scientific inquiry; (2) guidelines to help astrobiology students formulate and self-assess questions regarding various scientific content and imagery; and (3) a practical exercise where students were allowed to watch a scientific presentation and practice their analytical skills. Pre- and post-course surveys were used to assess the students' perceptions regarding creative and scientific inquiry and whether this activity impacted their understanding of the scientific process. Survey results indicate that the exercise helped improve students' science skills by promoting awareness regarding the role of creativity in scientific inquiry and building their confidence in formulating and assessing scientific questions. Together, the module and survey results confirm the need to include such inquiry-based activities into the higher education classroom, thereby helping students hone their critical thinking and question asking skill set and facilitating their professional development in astrobiology.

  1. Selection of appropriate medial branch of the optic tract by fibres of ventral retinal origin during development and in regeneration: an autoradiographic study in Xenopus

    1979-01-01

    The formation of the branches of the optic tract has been studied with the use of [ 3 H] -proline autoradiography, during development and during regeneration of the optic nerve in Xenopus with one compound ventral (VV) eye made by the embryonic fusion of two ventral eye fragments. The formation of the optic pathway was abnormal in that the lateral branch failed to develop, suggesting that fibres from a VV retina selectively entered the tectum via the medial branch during development. Three months after section of the optic nerve of a VV eye, regenerated fibres were present both in the contralateral and ipsilateral tecta. On the ipsilateral side regenerated fibres entered the tectum via the medial branch only. Retinal fibres entered the contralateral tectum through both branches in some animals and through the medial branch only in others. It is concluded that mechanical factors alone are insufficient to explain the phenomenon of selection of the appropriate medial branch fibres of ventral retinal origin either during development or in regeneration. Some form of fibre-substrate interaction seems to be necessary; and this ability of fibres from a VV eye to take the path appropriate for ventral retina argues strongly that the VV eye is not a regulated system in terms of cell specificities. 8author)

    2016-01-01

    Scientific reasoning has been studied from a variety of theoretical perspectives, which have tried to identify the underlying mechanisms responsible for the development of this particular cognitive process. Scientific reasoning has been defined as a problem-solving process that involves critical thinking in relation to content, procedural, and epistemic knowledge. The development of scientific reasoning in medical education was influenced by current paradigmatic trends, it could be traced along educational curriculum and followed cognitive processes. The purpose of the present review is to discuss the role of scientific reasoning in medical education and outline educational methods for its development. Current evidence suggests that medical education should foster a new ways of development of scientific reasoning, which include exploration of the complexity of scientific inquiry, and also take into consideration the heterogeneity of clinical cases found in practice.

    The infant leukemia-associated gene Ott1 (Rbm15) has broad regulatory effects within murine hematopoiesis. However, germ line Ott1 deletion results in fetal demise prior to embryonic day 10.5, indicating additional developmental requirements for Ott1. The spen gene family, to which Ott1 belongs, has a transcriptional activation/repression domain and RNA recognition motifs and has a significant role in the development of the head and thorax in Drosophila melanogaster. Early Ott1-deficient embryos show growth retardation and incomplete closure of the notochord. Further analysis demonstrated placental defects in the spongiotrophoblast and syncytiotrophoblast layers, resulting in an arrest of vascular branching morphogenesis. The rescue of the placental defect using a conditional allele with a trophoblast-sparing cre transgene allowed embryos to form a normal placenta and survive gestation. This outcome showed that the process of vascular branching morphogenesis in Ott1-deficient animals was regulated by the trophoblast compartment rather than the fetal vasculature. Mice surviving to term manifested hyposplenia and abnormal cardiac development. Analysis of global gene expression of Ott1-deficient embryonic hearts showed an enrichment of hypoxia-related genes and a significant alteration of several candidate genes critical for cardiac development. Thus, Ott1-dependent pathways, in addition to being implicated in leukemogenesis, may also be important for the pathogenesis of placental insufficiency and cardiac malformations.

  10. Built To Last: Using Iterative Development Models for Sustainable Scientific Software Development

    Science.gov (United States)

    Jasiak, M. E.; Truslove, I.; Savoie, M.

    2013-12-01

    In scientific research, software development exists fundamentally for the results they create. The core research must take focus. It seems natural to researchers, driven by grant deadlines, that every dollar invested in software development should be used to push the boundaries of problem solving. This system of values is frequently misaligned with those of the software being created in a sustainable fashion; short-term optimizations create longer-term sustainability issues. The National Snow and Ice Data Center (NSIDC) has taken bold cultural steps in using agile and lean development and management methodologies to help its researchers meet critical deadlines, while building in the necessary support structure for the code to live far beyond its original milestones. Agile and lean software development and methodologies including Scrum, Kanban, Continuous Delivery and Test-Driven Development have seen widespread adoption within NSIDC. This focus on development methods is combined with an emphasis on explaining to researchers why these methods produce more desirable results for everyone, as well as promoting developers interacting with researchers. This presentation will describe NSIDC's current scientific software development model, how this addresses the short-term versus sustainability dichotomy, the lessons learned and successes realized by transitioning to this agile and lean-influenced model, and the current challenges faced by the organization.

  11. Peroxisome protein transportation affects metabolism of branched-chain fatty acids that critically impact growth and development of C. elegans.

    Directory of Open Access Journals (Sweden)

    Rencheng Wang

    Full Text Available The impact of specific lipid molecules, including fatty acid variants, on cellular and developmental regulation is an important research subject that remains under studied. Monomethyl branched-chain fatty acids (mmBCFAs are commonly present in multiple organisms including mammals, however our understanding of mmBCFA functions is very limited. C. elegans has been the premier model system to study the functions of mmBCFAs and their derived lipids, as mmBCFAs have been shown to play essential roles in post-embryonic development in this organism. To understand more about the metabolism of mmBCFAs in C. elegans, we performed a genetic screen for suppressors of the L1 developmental arrest phenotype caused by mmBCFA depletion. Extensive characterization of one suppressor mutation identified prx-5, which encodes an ortholog of the human receptor for the type-1 peroxisomal targeting signal protein. Our study showed that inactivating prx-5 function compromised the peroxisome protein import, resulting in an increased level of branched-chain fatty acid C17ISO in animals lacking normal mmBCFA synthesis, thereby restoring wild-type growth and development. This work reveals a novel connection between peroxisomal functions and mmBCFA metabolism.

    Full Text Available In recent decades, research has growth Increasingly in Iran and, consequently, the country has risen dramatically in world rankings, based on the number of scientific documents. The impressive growth of the number of Iran researches, research experts increasingly focus on "research impact", and repeated emphasize on the issue of "use of research to improve society" in Iran superior governmental documents, leaded some researchers to investigate "how much Iran researches are effective?" They showed that these researches have in general been ineffective. Therefore, their efficacy should be evaluated which is the main purpose of this study. In this regard, using the Descriptive-Analytical method and valid secondary data and statistics, the results of Citation Analysis of Iran research outcomes were compared with other countries. Central questions of this study were respectively about «the quality of Iran whole researches (1996-2014», «the quality of top researches (2005-2014», «comparing the quality of whole researches with quality of top researches», and «the quality of Iran's Persian (2011-2012 and English (2014 scientific journals». For this purpose, based on the reliable data from valid databases (Thomson Reuters, Scopus and ISC, the value and rank of Iran at different citation related indices were extracted or calculated.

  19. Estimating the Natural Flow Regime of Rivers With Long-Standing Development: The Northern Branch of the Rio Grande

    Science.gov (United States)

    Blythe, Todd L.; Schmidt, John C.

    2018-02-01

    An estimate of a river's natural flow regime is useful for water resource planning and ecosystem rehabilitation by providing insight into the predisturbance form and function of a river. The natural flow regime of most rivers has been perturbed by development during the 20th century and in some cases, before stream gaging began. The temporal resolution of natural flows estimated using traditional methods is typically not sufficient to evaluate cues that drive native ecosystem function. Additionally, these traditional methods are watershed specific and require large amounts of data to produce accurate results. We present a mass balance method that estimates natural flows at daily time step resolution for the northern branch of the Rio Grande, upstream from the Rio Conchos, that relies only on easily obtained streamflow data. Using an analytical change point method, we identified periods of the measured flow regime during the 20th century for comparison with the estimated natural flows. Our results highlight the significant deviation from natural conditions that occurred during the 20th century. The total annual flow of the northern branch is 95% lower than it would be in the absence of human use. The current 2 year flood has decreased by more than 60%, is shorter in duration, and peaks later in the year. When compared to unregulated flows estimated using traditional mass balance accounting methods, our approach provides similar results.

    The Cell processor is one of the most powerful processors on the market, and researchers in the earth sciences may find its parallel architecture to be very useful. A cell processor, with 7 cores, can easily be obtained for experimentation by purchasing a PlayStation 3 (PS3) and installing linux and the IBM SDK. Each core of the PS3 is capable of 25 GFLOPS giving a potential limit of 150 GFLOPS when using all 6 SPUs (synergistic processing units) by using vectorized algorithms. We have used the Cell's computational power to create a program which takes simulated tsunami datasets, parses them, and returns a colorized height field image using ray casting techniques. As expected, the time required to create an image is inversely proportional to the number of SPUs used. We believe that this trend will continue when multiple PS3s are chained using OpenMP functionality and are in the process of researching this. By using the Cell to visualize tsunami data, we have found that its greatest feature is its power. This fact entwines well with the needs of the scientific community where the limiting factor is time. Any algorithm, such as the heat equation, that can be subdivided into multiple parts can take advantage of the PS3 Cell's ability to split the computations across the 6 SPUs reducing required run time by one sixth. Further vectorization of the code can allow for 4 simultanious floating point operations by using the SIMD (single instruction multiple data) capabilities of the SPU increasing efficiency 24 times.

    The Chemical Weapons Convention (CWC) was drafted with the recognition that it is impossible to envision every way in which toxic chemicals might be used for aggressive purposes. As terrorist organizations and rogue states replace the major powers as the most likely candidates to employ chemical weapons, the agents of choice may differ from those developed for battlefield use. Twenty- first century chemical warfare may target civilians or agricultural production, and clandestine production-facilities may manufacture toxic agents from chemical precursors, not monitored under the CWC control regime. The effects (on CWC implementation) of changing industrial technologies, including ongoing developments in chemical process technology, dual-use industrial chemicals, and rapid methods for discovering biologically active chemicals, are considerable Also considered is how commercial technologies could be misused for the development of novel chemical weapons, and how such abuses might be detected and monitored.

    Devoli, G.

    2012-04-01

    A successful landslide risk reduction program requires that the society is aware and understand the landslide problems within the geographic area involved. Central organizations that manage national landslide risks should: a) create and systematically applied natural hazard laws/national landslide strategies, where roles and limits of responsibilities of federal, state, provincial, municipal and private entities are well defined; c) establish fruitful multidisciplinary and interinstitutional collaboration among scientists; d) provide good risk assessments in which landslide experts report transparently what is really known and the limitations of methods and tools used; e) share and systematically communicate their knowledge more effectively with all private and public stakeholders involved, paying attention to providing balanced information about risks and addressing inevitable uncertainties; f) support the mass-media in spreading correct scientific information; g) perform serious risk and cost-benefit analyses before mitigation measures are realized; h) assist local authorities in the application of land-use planning policies and g) built trust and confidence by means of a continuous contact and communication with the public and local authorities. However, this is not yet achieved, not even in developed countries where, in theory, more economical resources are available and people are better educated then in developing countries. Herein I make some observations on how national landslide prevention efforts are being organized in two countries (Nicaragua and Norway), where I have been worked at governmental agencies as landslide expert in the last 10 years. I start describing similarities and differences between the countries and try to compare practices and experiences. The analysis was motivated by the following questions: Why after so many years of landslide mapping and investigations, landslide prevention is not good and effective as it should be? Is this

    Over 60 technical experts of the reactor safety research division of the Gesellschaft fuer Anlagen- und Reaktorsicherheit (GRS) gGmbH are developing and validating reliable methods and computer codes - summarized under the term nuclear simulation chain - for the safety-related assessment for all types of nuclear power plants (NPP) and other nuclear facilities considering the current state of science and technology. This nuclear simulation chain has to be able to simulate and assess all relevant physical processes and phenomena for all operating states and (severe) accidents. In the present contribution, the nuclear simulation chain developed and applied by GRS as well as selected examples of its application are presented. The latter demonstrate impressively the width of its scope and its performance. The GRS codes can be passed on request to other (national as well as international) organizations. This contributes to a worldwide increase of the nuclear safety standards. The code transfer is especially important for developing and emerging countries lacking the financial means and/or the necessary know-how for this purpose. At the end of this contribution, the respective course of action is described.

    Branched-chain amino acids (BCAAs), viz., L-isoleucine, L-leucine, and L-valine, are essential amino acids that cannot be synthesized in higher organisms and are important nutrition for humans as well as livestock. They are also valued as synthetic intermediates for pharmaceuticals. Therefore, the demand for BCAAs in the feed and pharmaceutical industries is increasing continuously. Traditional industrial fermentative production of BCAAs was performed using microorganisms isolated by random mutagenesis. A collection of these classical strains was also scientifically useful to clarify the details of the BCAA biosynthetic pathways, which are tightly regulated by feedback inhibition and transcriptional attenuation. Based on this understanding of the metabolism of BCAAs, it is now possible for us to pursue strains with higher BCAA productivity using rational design and advanced molecular biology techniques. Additionally, systems biology approaches using augmented omics information help us to optimize carbon flux toward BCAA production. Here, we describe the biosynthetic pathways of BCAAs and their regulation and then overview the microorganisms developed for BCAA production. Other chemicals, including isobutanol, i.e., a second-generation biofuel, can be synthesized by branching the BCAA biosynthetic pathways, which are also outlined.

    The Kuwait program encompasses five complimentary areas. These are: the energy data base and technology assessment program, the energy conservation program, the electric power program, the solar energy program, and the energy policy analysis program. The accomplishments up until 1980 of the energy activities at KISR include activities in the solar cooling area, solar electric power generation, solar water desalinatin, and in solar agriculture applications. Furthermore there were some activities in the energy conservation area with emphasis on the use of insulating materials and the thermal response of buildings for energy conservation in the building sector. At present major project activities concentrate on energy conservation with emphasis on the development of an energy building code for Kuwait and an experimental and theoretical evaluation of various energy conservation alternatives for Kuwaiti buildings. In the solar area the emphasis will continue to be in the solar cooling area with possible introduction of Rankine Cycle Cooling as a more viable alternative to absorption cooling than has been experienced so far.

    Center for Multiscale Modeling of Atmospheric Processes (CMMAP) is a National Science Foundation Science and Technology Center focused on improving the representation of cloud processes in climate models. The Center is divided into three sections including Knowledge Transfer, Research, and Education and Diversity. The Science Education and Diversity mission is to educate and train people with diverse backgrounds in Climate and Earth System Science by enhancing teaching and learning and disseminating science results through multiple media. CMMAP is partnering with two local school districts to host an annual global climate conferences for high school students. The 2008 Colorado Global Climate Conference seeks "To educate students on global and local climate issues and empower them to se their knowledge." The conference is sponsored by CMMAP, The Governor's Energy Office, Poudre School District, Thompson School District, Clif Bar, and Ben and Jerry's Scoop Shop of Fort Collins. The conference seeks to inspire students to pursue future education and careers in science fields. Following an opening welcome from the Governor's Energy Office, Keynote Piers Sellers will discuss his experiences as an atmospheric scientist and NASA astronaut. Students will then attend 3 out of 16 breakout sessions including such sessions as "Hot poems, Cool Paintings, and the treasures of Antiquity of Climate Change", "Mitigation vs Adaptation", "Bigfoot Walks(What Size is our carbon footprint?)" "The Wedges: Reduc ing Carbon Emissions", and "We the People: Climate and Culture of Climate Change" to name a few. Using The Governor's High School Conference on the Environment sponsored by the Wisconsin Center for Environmental Education as a model we are developing statewide partnerships to bring high school students together to look at global climate issues that will impact their future and of which they can be part of the solution through their education and career paths.

    In most of the countries across the globe, health is seen as a priority. The European Commission (2013), for example, considers health as a precondition for economic prosperity given that people’s health influences economic outcomes in terms of productivity, labor supply, human capital and public spending. Accordingly, the Commission places health in one of the big Societal Challenges (‘health, demographic change and wellbeing’) in Horizon 2020. Part of the investment on research and development is devoted to specific diseases. In order to assess whether scientific research is targeting the most pressing diseases, some studies have tried to analyze the degree of alignment between the funding allocated to specific diseases and the burden of disease (e.g. Gillum et al, 2011; Kingel et al, 2014). Others, like Evans et al (2014), focus on the relationship between research outputs dealing with specific diseases and the burden of disease. (Author)

  15. Scientific reasoning skills development in the introductory biology courses for undergraduates

    Schen, Melissa S.

    Scientific reasoning is a skill of critical importance to those students who seek to become professional scientists. Yet, there is little research on the development of such reasoning in science majors. In addition, scientific reasoning is often investigated as two separate entities: hypothetico-deductive reasoning and argumentation, even though these skills may be linked. With regard to argumentation, most investigations look at its use in discussing socioscientific issues, not in analyzing scientific data. As scientists often use the same argumentation skills to develop and support conclusions, this avenue needs to be investigated. This study seeks to address these issues and establish a baseline of both hypothetico-deductive reasoning and argumentation of scientific data of biology majors through their engagement in introductory biology coursework. This descriptive study investigated the development of undergraduates' scientific reasoning skills by assessing them multiple times throughout a two-quarter introductory biology course sequence for majors. Participants were assessed at the beginning of the first quarter, end of the first quarter, and end of the second quarter. A split-half version of the revised Lawson Classroom Test of Scientific Reasoning (LCTSR) and a paper and pencil argumentation instrument developed for this study were utilized to assess student hypothetico-deductive reasoning and argumentation skills, respectively. To identify factors that may influence scientific reasoning development, demographic information regarding age, gender, science coursework completed, and future plans was collected. Evidence for course emphasis on scientific reasoning was found in lecture notes, assignments, and laboratory exercises. This study did not find any trends of improvement in the students' hypothetico-deductive reasoning or argumentation skills either during the first quarter or over both quarters. Specific difficulties in the control of variables and

    Responsible conduct of research training typically includes only a subset of the issues that ought to be included in science ethics and sometimes makes ethics appear to be a set of externally imposed rules rather than something intrinsic to scientific practice. A new approach to science ethics training based upon Pennock's notion of the scientific virtues may help avoid such problems. This paper motivates and describes three implementations-theory-centered, exemplar-centered, and concept-centered-that we have developed in courses and workshops to introduce students to this scientific virtue-based approach.

    The aim of this study is to develop lesson plans and student worksheets based socio-scientific issues on pollution environmental topic for seventh-grade junior high school students. Environmental pollution topic split into several subtopics namely air pollution, water pollution and soil pollution. The composing of lesson plans were developed based on socio-scientific issues with five stages, namely (1) Motivate; (2) Challenge; (3) Collect scientific evidence; (4) Analyse the evidence; (5) Build knowledge and make connections; and (6) Use evidence. While student worksheets contain articles on socio-scientific issues, practice, and there are a few questions to determine students’ reasoning. The method that is used in this research is research and development (R & D method). Development model used in this study is a model of Plomp that consists of four stages, namely: (1) Initial Research; (2) Design; (3) Realization or Construction; (4) Testing, evaluation and revision; (5) Implementation, while the research was limited to the fourth stage. Lesson plans and student worksheets based on socio-scientific issues was validated through an expert validation. The result showed that lesson plans and student worksheets based socio-scientific issues on pollution theme have a very decent and be able to apply in science classroom.

  18. Learning by doing? Prospective elementary teachers' developing understandings of scientific inquiry and science teaching and learning

    Haefner, Leigh Ann; Zembal-Saul, Carla

    This study examined prospective elementary teachers' learning about scientific inquiry in the context of an innovative life science course. Research questions included: (1) What do prospective elementary teachers learn about scientific inquiry within the context of the course? and (2) In what ways do their experiences engaging in science investigations and teaching inquiry-oriented science influence prospective elementary teachers' understanding of science and science learning and teaching? Eleven prospective elementary teachers participated in this qualitative, multi-participant case study. Constant comparative analysis strategies attempted to build abstractions and explanations across participants around the constructs of the study. Findings suggest that engaging in scientific inquiry supported the development more appropriate understandings of science and scientific inquiry, and that prospective teachers became more accepting of approaches to teaching science that encourage children's questions about science phenomena. Implications include careful consideration of learning experiences crafted for prospective elementary teachers to support the development of robust subject matter knowledge.

    The public in general does not necessarily have enough knowledge for the reasonable decision making in the application of scientific and technological development even in the ear of the Information Society. However strongly the necessity of the consensus in the scientific policy like nuclear R and D is required, it is impossible to attain the goal, unless the scientific literacy of the general public is. In order to improve it the role of the scientific museum as a social educational facility is very important. In this respect, there still remains vast room to improve in the Japanese museum system and its activities. The concept of the 'Central Scientific and Technological Museum-Institute', which also operates very small-sized reactor for the educational use, is developed in this paper. (author)

    At this moment, at the starting time of the program on restoration of a large irrigation in Russia till 2020, the scientific and technical community of irrigation branch does not have clear vision on how to promote a development of irrigated agriculture and without repeating of mistakes having a place in the past. In many respects absence of a vision is connected to serious backlog of a scientific and technical and informational and technological level of development of domestic irrigation branch from advanced one. Namely such level of development is necessary for the resolving of new problems in new conditions of managing, and also for adequate answers to new challenges from climate and degradation of ground & water resources, as well as a rigorous requirement from an environment. In such important situation for irrigation branch when it is necessary quickly generate a scientific and technical politics for the current decade for maintenance of translation of irrigated agriculture in the Russian Federation on a new highly effective level of development, in our opinion, it is required to carry out open discussion of needs and requirements as well as a research for a adequate solutions. From political point of view a framework organized in FP6 DESIRE 037046 project is an example of good practice that can serve as methodical approach how to organize and develop such processes. From technical point of view a technology of operational management of irrigation at large scale presents a prospective alternative to the current type of management based on planning. From point of view ICT operational management demands creation of a new platform for the professional environment of activity. This platform should allow to perceive processes in real time, at their partial predictability on signals of a straight line and a feedback, within the framework of variability of decision making scenarious, at high resolution and the big ex-awning of sensor controls and the gauges

    This report collects and uses available data to reexamine the criteria for controlling primary loads in nuclear piping branch connections as expressed in Section III of the ASME Boiler and Pressure Vessel Code. In particular, the primary load stress indices given in NB-3650 and NB-3683 are reexamined. The report concludes that the present usage of the stress indices in the criteria equations should be continued. However, the complex treatment of combined branch and run moments is not supported by available information. Therefore, it is recommended that this combined loading evaluation procedure be replaced for primary loads by the separate leg evaluation procedure specified in NC/ND-3653.3(c) and NC/ND-3653.3(d). No recommendation is made for fatigue or secondary load evaluations for Class 1 piping. Further work should be done on the development of better criteria for treatment of combined branch and run moment effects

    In this short review we will show how the new scientific development mainly born in the western countries has produced since the end of 1700s an enormous increase in the level of life and of the number of their inhabitant, as never happened since the beginning of the human species. With the export of the scientific and technological culture in the other countries, like eastern Europe, in north and south America, and later in China and India (to quote the main examples), also their welfare condition have increased or are developing now. For what is concerning the second part of this short review, we try to explain why the most important future needs would be to insert, step by step, the developing countries inside the community of "interacting minds", in order to propagate the scientific culture (but not only) and to make it evolving by the contribution of the full humanity.

    The development and safety evaluation of a nuclear waste geologic repository require a proper scientific understanding of the site response. Such scientific understanding depends on information from a number of geoscience disciplines, including geology, geophysics, geochemistry, geomechanics and hydrogeology. The information comes in four stages: (1) general regional survey data base, (2) surface-based testing, (3) exploratory shaft testing, and (4) repository construction and evaluation. A discussion is given on the dynamic use of the information through the different stages. We point out the need for abstracting, deriving and updating a quantitative spatial and process model (QSPM) to develop a scientific understanding of site responses as a crucial element in the dynamic procedure. 2 figs

    2018-01-01

    Full Text Available Introduction. The scientific schools serve as engines of development of science and the training centers for scientists. At the same time, the identity of the founder and head of the scientific school is of great importance; this person has to have unique theoretical thinking, talent and the researcher’s intuition, to be purposeful, responsible for generation of the ideas and personally interested in the development of current scientific problems, as well as to have distinctive managerial and pedagogical qualities.The aim of this article is to analyse the establishment and “evolution” of the scientific school of G. M. Romantsev, the Academician of the Russian Academy of Education; to identify the prospects for the main directions of the school development.Methodology and research methods. The study was based on the hermeneutic method of interpretation and understanding of scientific texts; general scientific methods of analysis, synthesis, comparison, generalization and interpretation of available scientific heritage were applied. Results and scientific novelty. The authors of the present publication have made an attempt to comprehend the content of scholarly writings by G. M. Romantsev and his followers within the framework of the scientific school; a theoretical model of professional pedagogical education in Russia was designed by them. It was found out that most of the research publications are interdisciplinary, often conducted at the intersection of Pedagogy, Psychology, Philosophy, Law and Economics; research and practice nature of most of the studies was defined: theoretical studies are traditionally accompanied by innovative experimental activity. The place of Vocational Pedagogy in the system of pedagogical sciences was proved; its role as theoretical and methodological foundations of vocational-pedagogical education was highlighted as well. The key theoretical and methodological premises of this type of education are formulated

    This study aims to explore the extent to which the use of analogy reasoning when students conduct conjecture in developing the scientific approach, so that the knowledge of the students can be used to build new knowledge. Analysis was conducted on student learning outcomes in Ciamis district. Based on these results, it was found the teacher not give an opportunity to the students to make conjecture on the students in problem solving as well as the construction of new knowledge. Moreover, teachers do not take advantage of analogical reasoning and scientific approach in constructing new knowledge.

  12. Development and Preliminary Validation of a New Measure of Values in Scientific Work.

    Science.gov (United States)

    English, Tammy; Antes, Alison L; Baldwin, Kari A; DuBois, James M

    2018-04-01

    In this paper we describe the development and initial psychometric evaluation of a new measure, the values in scientific work (VSW). This scale assesses the level of importance that investigators attach to different VSW. It taps a broad range of intrinsic, extrinsic, and social values that motivate the work of scientists, including values specific to scientific work (e.g., truth and integrity) and more classic work values (e.g., security and prestige) in the context of science. Notably, the values represented in this scale are relevant to scientists regardless of their career stage and research focus. We administered the VSW and a measure of global values to 203 NIH-funded investigators. Exploratory factor analyses suggest the delineation of eight VSW, including autonomy, research ethics, social impact, income, collaboration, innovation and growth, conserving relationships, and job security. These VSW showed predictable and distinct associations with global values. Implications of these findings for work on research integrity and scientific misconduct are discussed.

  13. Students' socio-scientific reasoning on controversies from the viewpoint of education for sustainable development

    2009-09-01

    In this article, we study third-year university students' reasoning about three controversial socio-scientific issues from the viewpoint of education for sustainable development: local issues (the reintroduction of bears in the Pyrenees in France, wolves in the Mercantour) and a global one (global warming). We used the theoretical frameworks of social representations and of socio-scientific reasoning. Students' reasoning varies according to the issues, in particular because of their emotional proximity with the issues and their socio-cultural origin. About this kind of issues, it seems pertinent to integrate into the operations of socio-scientific reasoning not only the consideration of values, but also the analysis of the modes of governance and the place given to politics.

    The scientific evidences on the relationship between food and health have given place to a new food market of rapid growth in the last years: the market of the functional food. Though the interest of maintaining or improving the state of health by means of the consumption of traditional food with bioactive ingredients added is undoubtedly high, the Spanish population, increasingly formed and informed, is unwilling to consume functional food, until these possess a scientific rigorous base. This article presents a review of the scientific bases that support the development of functional meat products with balanced ratio omega-6/omega-3 and a combination of synergic antioxidants, among them an extract of rosemary obtained by means of extraction with supercritical CO2.

    A scientific approach is a learning process designed so that learners can actively construct concepts, encourage learners to find out from various sources through observation, and not just be told. Therefore, learning by scientific approach offers a solution, because the goals, principles, and stages of the scientific approach allow for a good understanding of the students. Because of the absence of teaching materials “polyhedron geometry based on scientific approach” which is widely published in Indonesia, then we need to develop the teaching materials. The results obtained in this study are the tasks presented on teaching materials with a scientific approach both in defining the cube and the beam, identify and solve problems related to the properties and elements of cubes and beams, making cube and beam nets, solving problems related to cube and beam nets, solving problems related to cube and beam surface area. Beginning with the difficulties students face. Then, based on the results of interviews with teachers and analysis of student difficulties on each indicator, researchers revise the teaching materials as needed. Teaching materials that have not found any more student difficulties then the teaching materials are considered valid and ready for use by teachers and students.

  16. Fusion Energy: Contextual Analysis of the Information Panels Developed by the Scientific Community versus Citizen Discourse

    2014-01-01

    The report presents an exploratory study on the impact of scientific dissemination, particularly a comparative analysis of two discourses on fusion energy as an alternative energy future. The report introduces a comparative analysis of the institutional discourse, as portrayed by the scientific jargon used in a European travelling exhibition on nuclear fusion Fusion Expo, and the social discourse, as illustrated by a citizen deliberation on this very same exhibition. Through textual analysis, the scientific discourse as deployed in the informative panels at the Fusion Expo is compared with the citizen discourse as developed in the discussions within the citizen groups. The ConText software was applied for such analysis. The purpose is to analyze how visitors assimilate, capture and understand highly technical information. Results suggest that, in despite of convergence points, the two discourses present certain differences, showing diverse levels of communication. The scientific discourse shows a great profusion of formalisms and technicalities of scientific jargon. The citizen discourse shows abundance of words associated with daily life and the more practical aspects (economy, efficiency), concerning institutional and evaluative references. In sum, the study shows that although there are a few common communicative spaces, there are still very few turning points. These data indicate that although exhibitions can be a good tool to disseminate advances in fusion energy in informal learning contexts, public feedback is a powerful tool for improving the quality of social dialogue.

  19. The Development of Genetics in the Light of Thomas Kuhn's Theory of Scientific Revolutions.

    2015-01-01

    The concept of a paradigm is in the key position in Thomas Kuhn's theory of scientific revolutions. A paradigm is the framework within which the results, concepts, hypotheses and theories of scientific research work are understood. According to Kuhn, a paradigm guides the working and efforts of scientists during the time period which he calls the period of normal science. Before long, however, normal science leads to unexplained matters, a situation that then leads the development of the scientific discipline in question to a paradigm shift--a scientific revolution. When a new theory is born, it has either gradually emerged as an extension of the past theory, or the old theory has become a borderline case in the new theory. In the former case, one can speak of a paradigm extension. According to the present author, the development of modern genetics has, until very recent years, been guided by a single paradigm, the Mendelian paradigm which Gregor Mendel launched 150 years ago, and under the guidance of this paradigm the development of genetics has proceeded in a normal fashion in the spirit of logical positivism. Modern discoveries in genetics have, however, created a situation which seems to be leading toward a paradigm shift. The most significant of these discoveries are the findings of adaptive mutations, the phenomenon of transgenerational epigenetic inheritance, and, above all, the present deeply critical state of the concept of the gene.

  20. Facilitating Progress towards the Sustainable Development Goals through Open Scientific Data and Indicators

    2015-12-01

    The Sustainable Development Goals (SDGs) represent an unprecedented international commitment to a shared future encompassing sustainable management of the planet and significant improvement in the human condition around the world. The scientific community has both an ethical responsibility and substantial self-interest—as residents of this planet—to help the world community to better understand the complex, interlinked behavior of human and environmental systems and to elucidate pathways to achieve long-term sustainability. Critical to making progress towards the SDGs is the open availability of timely, reliable, usable, and well integrated data and indicators relevant to all SDGs and associated targets. Such data and indicators will not only be valuable in monitoring and evaluation of progress, but also in developing policies and making decisions on environmental and societal issues affecting sustainability from local to global scales. The open availability of such data and indicators can help motivate performance, promote accountability, and facilitate cooperation. A range of scientific, technical, organizational, political, and resource challenges need to be addressed in developing a coherent SDG monitoring and indicator framework. For example, assembling and integrating diverse data on consistent spatial and temporal scales across the relevant natural, social, health, and engineering sciences pose both scientific and technical difficulties, and may require new ways to interlink and organize existing cyberinfrastructure, reconcile different data policy regimes, and fund integration efforts. New information technologies promise more timely and efficient ways of collecting many types of data, but may also raise privacy, control, and equity issues. Scientific review processes to ensure data quality need to be coordinated with the types of quality control and review employed by national statistical agencies for trusted economic and social statistics.

    The purpose of this study was to develop and validate two survey instruments to evaluate high school students' scientific epistemic beliefs and goal orientations in learning science. The initial relationships between the sampled students' scientific epistemic beliefs and goal orientations in learning science were also investigated. A final valid sample of 600 volunteer Taiwanese high school students participated in this survey by responding to the Scientific Epistemic Beliefs Instrument (SEBI) and the Goal Orientations in Learning Science Instrument (GOLSI). Through both exploratory and confirmatory factor analyses, the SEBI and GOLSI were proven to be valid and reliable for assessing the participants' scientific epistemic beliefs and goal orientations in learning science. The path analysis results indicated that, by and large, the students with more sophisticated epistemic beliefs in various dimensions such as Development of Knowledge, Justification for Knowing, and Purpose of Knowing tended to adopt both Mastery-approach and Mastery-avoidance goals. Some interesting results were also found. For example, the students tended to set a learning goal to outperform others or merely demonstrate competence (Performance-approach) if they had more informed epistemic beliefs in the dimensions of Multiplicity of Knowledge, Uncertainty of Knowledge, and Purpose of Knowing.

  2. Instructional games: Scientific language use, concept understanding, and attitudinal development of middle school learners

    Mongillo, Geraldine

    The purpose of this qualitative study was to discover the influence of instructional games on middle school learners' use of scientific language, concept understanding, and attitude toward learning science. The rationale for this study stemmed from the lack of research concerning the value of play as an instructional strategy for older learners. Specifically, the study focused on the ways in which 6 average ability 7th grade students demonstrated scientific language and concept use during gameplay. The data were collected for this 6-week study in a southern New Jersey suburban middle school and included audio recordings of the 5 games observed in class, written documents (e.g., student created game questions, self-evaluation forms, pre- and post-assessments, and the final quiz) interviews, and researcher field notes. Data were coded and interpreted borrowing from the framework for scientific literacy developed by Bybee (1997). Based on the findings, the framework was modified to reflect the level of scientific understanding demonstrated by the participants and categorized as: Unacquainted, Nominal, Functional, and Conceptual. Major findings suggested that the participants predominantly achieved the Functional level of scientific literacy (i.e., the ability to adequately and appropriately use scientific language in both written and oral discourse) during games. Further, it was discovered that the participants achieved the Conceptual level of scientific literacy during gameplay. Through games participants were afforded the opportunity to use common, everyday language to explore concepts, promoted through peer collaboration. In games the participants used common language to build understandings that exceeded Nominal or token use of the technical vocabulary and concepts. Additionally, the participants reported through interviews and self-evaluation forms that their attitude (patterns included: Motivation, Interest, Fun, Relief from Boredom, and an Alternate Learning

    The need for developing land sparing or land sharing policies for protecting the environment has been a polarized debate in the scientific literature. Some studies show that "spared" landscapes with clearly separated intensive agriculture and pristine forest are better for biodiversity and other...... ecosystem services, whereas others demonstrate the benefits of "shared" mosaic landscapes composed of a mix of forest types, agricultural fields, grassland, and plantations. Increasingly, these scientific views have been depolarized, recognizing that both shared and spared landscapes have a role to play......, depending on the context. However, it is less clear from the literature what drives actual policy-making related to land sparing and land sharing in developing countries and what the outcomes of these policies are. We therefore reviewed the international peer-reviewed literature for evidence of policies...

    Lindenmayer, A; Schoen, H F

    1967-08-01

    The initiation of perithecia in the homothallic ascomycete Sordaria fimicola was completely suppressed, without seriously inhibiting vegetative growth, by growing the fungus on an agar medium containing one of the following additions: 1) 1 mum 5-fluorouracil, 2) 10 to 100 mum 6-azauracil, 8-azaguanine or 8-azaadenine, 3) 50 to 500 mum cyanide or azide, 4) 5% (w/v) casein hydrolysate. In contrast to the selective activity of the analogues of 3 RNA bases, whose inhibition could be reversed by the appropriate normal bases only, none of the analogues of thymine were active, neither were the thio-derivatives of RNA bases. Other inhibitors of RNA and protein synthesis, like actinomycin D, puromycin and cycloheximide, were also without selective activity, although the last of these inhibited perithecial maturation at 0.1 mum concentration but not initiation. Amino acid analogues were inactive, as were the metabolic inhibitors thiourea, 2,4-dinitrophenol and fluoride. The compounds which inhibited the formation of perithecia also lowered the branching frequency of leading hyphae, but not their linear growth rates. Consequently, the branch densities were diminished in their presence. Hypotheses to account for these findings are discussed in terms of inhibition of growth in general, of the synthesis of some specific messenger RNAs, and of RNA-mediated transport across membranes, the last of which seeming the most fruitful for further work.

The compounds which inhibited the formation of perithecia also lowered the branching frequency of leading hyphae, but not their linear growth rates. Consequently, the branch densities were diminished in their presence. Hypotheses to account for these findings are discussed in terms of inhibition of growth in general, of the synthesis of some specific messenger RNAs, and of RNA-mediated transport across membranes, the last of which seeming the most fruitful for further work.

  18. Withholding answers during hands-on scientific investigations? Comparing effects on developing students' scientific knowledge, reasoning, and application

    Science.gov (United States)

    Zhang, Lin

    2018-03-01

    As more concerns have been raised about withholding answers during science teaching, this article argues for a need to detach 'withholding answers' from 'hands-on' investigation tasks. The present study examined students' learning of light-related content through three conditions: 'hands-on' + no 'withholding' (hands-on only: HO), 'hands-on' + 'withholding' (hands-on investigation with answers withheld: HOW), and no 'hands-on' + no 'withholding' (direction instruction: DI). Students were assessed in terms of how well they (1) knew the content taught in class; (2) reasoned with the learned content; and (3) applied the learned content to real-life situations. Nine classes of students at 4th and 5th grades, N = 136 in total, were randomly assigned to one of the three conditions. ANCOVA results showed that students in the hands-on only condition reasoned significantly better than those in the other two conditions. Students in this condition also seemed to know the content fairly better although the advance was not significant. Students in all three conditions did not show a statistically significant difference in their ability to apply the learned content to real-life situations. The findings from this study provide important contributions regarding issues relating to withholding answers during guided scientific inquiry.

  19. Key scientific issues in developing drinking water guidelines for perfluoroalkyl acids: Contaminants of emerging concern.

    Science.gov (United States)

    Post, Gloria B; Gleason, Jessie A; Cooper, Keith R

    2017-12-01

    Perfluoroalkyl acids (PFAAs), a group of synthetic organic chemicals with industrial and commercial uses, are of current concern because of increasing awareness of their presence in drinking water and their potential to cause adverse health effects. PFAAs are distinctive among persistent, bioaccumulative, and toxic (PBT) contaminants because they are water soluble and do not break down in the environment. This commentary discusses scientific and risk assessment issues that impact the development of drinking water guidelines for PFAAs, including choice of toxicological endpoints, uncertainty factors, and exposure assumptions used as their basis. In experimental animals, PFAAs cause toxicity to the liver, the immune, endocrine, and male reproductive systems, and the developing fetus and neonate. Low-dose effects include persistent delays in mammary gland development (perfluorooctanoic acid; PFOA) and suppression of immune response (perfluorooctane sulfonate; PFOS). In humans, even general population level exposures to some PFAAs are associated with health effects such as increased serum lipids and liver enzymes, decreased vaccine response, and decreased birth weight. Ongoing exposures to even relatively low drinking water concentrations of long-chain PFAAs substantially increase human body burdens, which remain elevated for many years after exposure ends. Notably, infants are a sensitive subpopulation for PFAA's developmental effects and receive higher exposures than adults from the same drinking water source. This information, as well as emerging data from future studies, should be considered in the development of health-protective and scientifically sound guidelines for PFAAs in drinking water.

    1982-01-01

    Computer graphics methods and tools are being used to a great extent in scientific research. The future development in this area will be influenced both by new hardware developments and by software advances. On the hardware sector, the development of the raster technology will lead to the increased use of colour workstations with more local processing power. Colour hardcopy devices for creating plots, slides, or movies will be available at a lower price than today. The first real 3D-workstations will appear on the marketplace. One of the main activities on the software sector is the standardization of computer graphics systems, graphical files, and device interfaces. This will lead to more portable graphical application programs and to a common base for computer graphics education.

  6. Social inequalities in the face of scientific and technological development: an antinomy or an historic problem?

    Science.gov (United States)

    Delgado, Guilherme Costa

    2017-07-01

    This paper aims to conduct a conceptual analysis of the relationship between scientific and technical progress and social equality, or the reduction of inequalities. We examine this relationship by drawing on three theoretical perspectives: 1) ethical economics, championed by classical economic thinkers and centered on utilitarian self-interest, 2) Mainstream theories of economic development espousing the endogenous link between labor productivity growth and technical progress, 3) the critique of theories of economic development that emerged in the second half of the twentieth century, including Celso Furtado's critique of the theory of underdevelopment, emphasizing the prevalence of egalitarian tendencies, and ecological economics, which suggest alternative paths to those set by "classical" theories of development. The fundamental antinomy posed by the title of this article, characterized by an intrinsic contradiction between technical progress and social equality, strictly presupposes the ethical economics perspective, dominated by the social relations that constitute the "social order".

    The significant progress in angle-resolved photoemission spectroscopy (ARPES) in last three decades has elevated it from a traditional band mapping tool to a precise probe of many-body interactions and dynamics of quasiparticles in complex quantum systems. The recent developments of deep ultraviolet (DUV, including ultraviolet and vacuum ultraviolet) laser-based ARPES have further pushed this technique to a new level. In this paper, we review some latest developments in DUV laser-based photoemission systems, including the super-high energy and momentum resolution ARPES, the spin-resolved ARPES, the time-of-flight ARPES, and the time-resolved ARPES. We also highlight some scientific applications in the study of electronic structure in unconventional superconductors and topological materials using these state-of-the-art DUV laser-based ARPES. Finally we provide our perspectives on the future directions in the development of laser-based photoemission systems.

    2016-11-01

    This review presents scientific and regulatory considerations for the development of solid oral modified release (MR) drug products. It includes a rationale for patient-focused development based on Quality-by-Design (QbD) principles. Product and process understanding of MR products includes identification and risk-based evaluation of critical material attributes (CMAs), critical process parameters (CPPs), and their impact on critical quality attributes (CQAs) that affect the clinical performance. The use of various biopharmaceutics tools that link the CQAs to a predictable and reproducible clinical performance for patient benefit is emphasized. Product and process understanding lead to a more comprehensive control strategy that can maintain product quality through the shelf life and the lifecycle of the drug product. The overall goal is to develop MR products that consistently meet the clinical objectives while mitigating the risks to patients by reducing the probability and increasing the detectability of CQA failures.

    2018-03-01

    Full Text Available Smart farming (SF involves the incorporation of information and communication technologies into machinery, equipment, and sensors for use in agricultural production systems. New technologies such as the internet of things and cloud computing are expected to advance this development, introducing more robots and artificial intelligence into farming. Therefore, the aims of this paper are twofold: (i to characterize the scientific knowledge about SF that is available in the worldwide scientific literature based on the main factors of development by country and over time and (ii to describe current SF prospects in Brazil from the perspective of experts in this field. The research involved conducting semi-structured interviews with market and researcher experts in Brazil and using a bibliometric survey by means of data mining software. Integration between the different available systems on the market was identified as one of the main limiting factors to SF evolution. Another limiting factor is the education, ability, and skills of farmers to understand and handle SF tools. These limitations revealed a market opportunity for enterprises to explore and help solve these problems, and science can contribute to this process. China, the United States, South Korea, Germany, and Japan contribute the largest number of scientific studies to the field. Countries that invest more in R&D generate the most publications; this could indicate which countries will be leaders in smart farming. The use of both research methods in a complementary manner allowed to understand how science frame the SF and the mains barriers to adopt it in Brazil.

    This review especially describes the dangerous pathogens research program in Azerbaijan (AJ) funded by the US Defense Threat Reduction Agency under the Cooperative Biological Engagement Program (CBEP) from 2011 through 2015. The objectives of the CBEP are to prevent the proliferation of biological weapons; to consolidate and secure collections of dangerous pathogens in central repositories; to strengthen biosafety and biosecurity of laboratory facilities; and to improve partner nations' ability to detect, diagnose, report, and respond to outbreaks of disease caused by especially dangerous pathogens. One of the missions of the CBEP is therefore to increase the research skills and proficiency of partner country scientists. The program aims to fulfill this mission by sponsoring scientific research projects that exercise the modern diagnostic techniques available in the CBEP-engaged laboratories and the enhanced disease surveillance/control programs. To strengthen the local scientists' ability to develop research ideas, write grant proposals, and conduct research independently, in-country CBEP integrating contractor personnel have mentored scientists across AJ and conducted workshops to address technical gaps. As a result of CBEP engagement, seven research projects developed and led by AJ scientists have been funded, and five projects are currently in various stages of implementation. The Defense Threat Reduction Agency has also sponsored AJ scientist participation at international scientific conferences to introduce and integrate them into the global scientific community. The efforts summarized in this review represent the first steps in an ongoing process that will ultimately provide AJ scientists with the skills and resources to plan and implement research projects of local and regional relevance.

    2018-03-01

    Full Text Available Two major green house gases (CO2 and CH4 can be converted into useful synthetic gas (H2 and CO during dry reforming of methane (DRM reaction, and a lot of scientific efforts has been made to develop efficient catalysts for dry reforming of methane (DRM. Noble metal-based catalysts can effectively assist DRM reaction, however they are not economically viable. Alternatively, non-noble based catalysts have been studied so far, and supported Ni catalysts have been considered as a promising candidate for DRM catalyst. Main drawback of Ni catalysts is its catalytic instability under operating conditions of DRM (>700 °C. Recently, it has been demonstrated that the appropriate choice of metal-oxide supports can address this issue since the chemical and physical of metal-oxide supports can prevent coke formation and stabilize the small Ni nanoparticles under harsh conditions of DRM operation. This mini-review covers the recent scientific findings on the development of supported Ni catalysts for DRM reaction, including the synthetic methods of supported Ni nanoparticles with high sintering resistance.

    2017-01-01

    The memory behavior in liquid crystals (LCs), although rarely observed, has made very significant headway over the past three decades since their discovery in nematic type LCs. It has gone from a mere scientific curiosity to application in variety of commodities. The memory element formed by numerous LCs have been protected by patents, and some commercialized, and used as compensation to non-volatile memory devices, and as memory in personal computers and digital cameras. They also have the low cost, large area, high speed, and high density memory needed for advanced computers and digital electronics. Short and long duration memory behavior for industrial applications have been obtained from several LC materials, and an LC memory with interesting features and applications has been demonstrated using numerous LCs. However, considerable challenges still exist in searching for highly efficient, stable, and long-lifespan materials and methods so that the development of useful memory devices is possible. This review focuses on the scientific and technological approach of fascinating applications of LC-based memory. We address the introduction, development status, novel design and engineering principles, and parameters of LC memory. We also address how the amalgamation of LCs could bring significant change/improvement in memory effects in the emerging field of nanotechnology, and the application of LC memory as the active component for futuristic and interesting memory devices.

    Scientific thinking is a predicate for scientific inquiry, and thus important to develop early in psychology students as potential future researchers. The present research is aimed at fathoming the contributions of formal and informal learning experiences to psychology students' development of scientific thinking during their 1st-year of study. We hypothesize that informal experiences are relevant beyond formal experiences. First-year psychology student cohorts from various European countries will be assessed at the beginning and again at the end of the second semester. Assessments of scientific thinking will include scientific reasoning skills, the understanding of basic statistics concepts, and epistemic cognition. Formal learning experiences will include engagement in academic activities which are guided by university authorities. Informal learning experiences will include non-compulsory, self-guided learning experiences. Formal and informal experiences will be assessed with a newly developed survey. As dispositional predictors, students' need for cognition and self-efficacy in psychological science will be assessed. In a structural equation model, students' learning experiences and personal dispositions will be examined as predictors of their development of scientific thinking. Commonalities and differences in predictive weights across universities will be tested. The project is aimed at contributing information for designing university environments to optimize the development of students' scientific thinking.

    Black, Maureen M; Pérez-Escamilla, Rafael; Rao, Sylvia Fernandez

    2015-11-01

    The Millennium Development Goals (MDGs) have contributed to unprecedented reductions in poverty and improvement in the lives of millions of men, women, and children in low- and middle-income countries. Yet, hundreds of millions of children under 5 y of age are not reaching their developmental potential. This article reviews the scientific basis for early childhood nutrition and child development interventions, the impact of integrated interventions on children's linear growth and cognitive development, and implementation strategies for integrated nutrition and child development programs. Advances in brain science have documented that the origins of adult health and well-being are grounded in early childhood, from conception through age 24 mo (first 1000 d) and extending to age 5 y (second 1000 d). Young children with adequate nutrition, nurturant caregiving, and opportunities for early learning have the best chances of thriving. Evidence from adoption, experimental, and quasi-experimental studies has shown that stunting prevention is sensitive during the first 1000 d, and sensitivity to child development interventions extends through the second 1000 d. Cognitive development responds to interventions post–1000 d with effect sizes that are inversely associated with initial age and length of program exposure. Integrated interventions need governance structures that support integrated policies and programming, with attention to training, supervision, and monitoring. The MDGs have been replaced by the Sustainable Development Goals (SDGs), with targets for the next 15 y. Achievement of the SDGs depends on children receiving adequate nutrition, nurturant caregiving, and learning opportunities from conception through age 5.

    Mortensen, Jonas Egmose; Eames, Malcolm; Nielsen, Kurt Aagaard

    As the effects of climate change is becoming increasingly visible scientific and technological development is often seen as a key component in political action towards future sustainability. Historically, however, it is not evident that science and technology per se lead to sustainable solutions....... To address this aspect of the challenge of sustainable development, this paper examines whether new approaches to upstream engagement in science and technology can further knowledge channels between academia and local communities, which can inspire more contextualised modes of knowledge production. Building...... on the insights from critical theory; newer conceptualisations of knowledge production; and the experiences from the Citizen Science for Sustainability action research programme, a number of principles towards more reflexive forms of community based public engagement in science and technology are proposed....

    Full Text Available Braverman and Finkelberg recently proposed the geometric Satake correspondence for the affine Kac-Moody group Gaff [Braverman A., Finkelberg M., arXiv:0711.2083]. They conjecture that intersection cohomology sheaves on the Uhlenbeck compactification of the framed moduli space of Gcpt-instantons on $R^4/Z_r$ correspond to weight spaces of representations of the Langlands dual group $G_{aff}^{vee}$ at level $r$. When $G = SL(l$, the Uhlenbeck compactification is the quiver variety of type $sl(r_{aff}$, and their conjecture follows from the author's earlier result and I. Frenkel's level-rank duality. They further introduce a convolution diagram which conjecturally gives the tensor product multiplicity [Braverman A., Finkelberg M., Private communication, 2008]. In this paper, we develop the theory for the branching in quiver varieties and check this conjecture for $G = SL(l$.

    We develop some useful techniques for integrating over Higgs branches in supersymmetric theories with 4 and 8 supercharges. In particular, we define a regularized volume for hyperkaehler quotients. We evaluate this volume for certain ALE and ALF spaces in terms of the hyperkaehler periods. We also reduce these volumes for a large class of hyperkaehler quotients to simpler integrals. These quotients include complex coadjoint orbits, instanton moduli spaces on R 4 and ALE manifolds, Hitchin spaces, and moduli spaces of (parabolic) Higgs bundles on Riemann surfaces. In the case of Hitchin spaces the evaluation of the volume reduces to a summation over solutions of Bethe ansatz equations for the non-linear Schroedinger system. We discuss some applications of our results. (orig.)

    2013-07-01

    Since the 1990s, science based ecological risk assessments constitute an essential tool for supporting decision making in the regulatory context. Using the European REACH Regulation as example, this article presents the challenges and opportunities for new scientific developments within the area of chemical control and environmental protection. These challenges can be sorted out in 3 main related topics (sets). In the short term, the challenges are directly associated with the regulatory requirements, required for facilitating a scientifically sound implementation of the different obligations for industry and authorities. It is important to mention that although the actual tools are different due to the regulatory requirements, the basic needs are still the same as those addressed in the early 1990s: understanding the ecological relevance of the predicted effects, including the uncertainty, and facilitating the link with the socio-economic assessment. The second set of challenges covers the opportunities for getting an added value from the regulatory efforts. The information compiled through REACH registration and notification processes is analyzed as source for new integrative developments for assessing the combined chemical risk at the regional level. Finally, the article discusses the challenge of inverting the process and developing risk assessment methods focusing on the receptor, the individual or ecosystem, instead of on the stressor or source. These approaches were limited in the past due to the lack of information, but the identification and dissemination of standard information, including uses, manufacturing sites, physical-chemical, environmental, ecotoxicological, and toxicological properties as well as operational conditions and risk management measures for thousands of chemicals, combined by the knowledge gathered through large scale monitoring programs and spatial information systems is generating new opportunities. The challenge is liking

    Soils hold a unique position at the nexus of the major global issues we face - socioeconomic injustices, health/nutrition and the rise in chronic disease, and environmental degradation/climate change. They serve as the base of our global economy; the source of food, of life; and are a dominant player in the provision of ecosystem services, upon which we all depend. As the millenial generation comes of age, inheriting the challenge of feeding nine billion on fewer acres with less impact amidst an uncertain climate, they often look upward to other planets or towards innovative technologies to dig us out, when a myriad of solutions lie right beneath their feet, unbeknownst to them. Millenials tend to be largely purpose-driven, adept at organizing and collaborating, and aware of their agency in facilitating change, but there is currently a vast disconnect between the scientific community and the general populace and an even larger disconnect between ourselves and the land. Educating millenials about the value and importance of soil provides a unique opportunity to empower and engage young minds in developing real, sustainable solutions. By illuminating the hidden world underfoot - its beauty, mystery and vibrancy - we can awaken a sense of awe and wonder, reconnect people to the natural world, and inspire a generation of explorers focused on the final frontier right here on Earth. Taking a page out of the industry playbook, wherein carefully crafted messaging campaigns are employed to tell clear, concise stories that "sell" to the masses and directly influence consumer habits; the scientific community can invoke the timeless art of storytelling to communicate soil science in an accessible way that evokes an emotional response, influences public opinion and inspires social change. While a plethora of quality, soil-related resources can be found on the web, there exists no centralized multimedia hub that is palatable to the masses and targeted at millenials; fusing

    Köchy, Kristian

    2010-03-01

    In the 1920s and 1930s three different but simultaneous approaches of philosophy of science can be distinguished: the logical approach of the physicist Rudolf Carnap, the logico-historical approach of the psychologist Kurt Lewin and the socio-historical approach of the medical scientist Ludwik Fleck. While the philosophies of Lewin and Fleck can be characterized as contextual appraisals which account for the interactions between particular sciences and their historical, socio-cultural or intellectual environments, Carnap's philosohy is narrowed to an internal methodology centered on scientific propositions and ogical structures in general. In addition to these differences in aim and practice of methodological analysis the estimation of the real disunity and diversity of the special branches of science differs. Instead of Carnap's ideal of a unified science from the new pluralistic point of view the evaluation of the empirical multiplicity of particular sciences obtains philosophical acceptance.

  10. Current perspectives on shoot branching regulation

    Cunquan YUAN,Lin XI,Yaping KOU,Yu ZHAO,Liangjun ZHAO

    2015-03-01

    Full Text Available Shoot branching is regulated by the complex interactions among hormones, development, and environmental factors. Recent studies into the regulatory mecha-nisms of shoot branching have focused on strigolactones, which is a new area of investigation in shoot branching regulation. Elucidation of the function of the D53 gene has allowed exploration of detailed mechanisms of action of strigolactones in regulating shoot branching. In addition, the recent discovery that sucrose is key for axillary bud release has challenged the established auxin theory, in which auxin is the principal agent in the control of apical dominance. These developments increase our understan-ding of branching control and indicate that regulation of shoot branching involves a complex network. Here, we first summarize advances in the systematic regulatory network of plant shoot branching based on current information. Then we describe recent developments in the synthesis and signal transduction of strigolactones. Based on these considerations, we further summarize the plant shoot branching regulatory network, including long distance systemic signals and local gene activity mediated by strigolactones following perception of external envi-ronmental signals, such as shading, in order to provide a comprehensive overview of plant shoot branching.

    2015-11-01

    Full Text Available Objective: To ensure that cyberinfrastructure for sharing scientific data is useful, system developers need to understand what scientists and other intended users do as well as the attitudes and beliefs that shape their behaviours. This paper introduces personas — detailed descriptions of an “archetypical user of a system” — as an approach for capturing and sharing knowledge about potential system users. Setting: Personas were developed to support development of the ‘DataONE’ (Data Observation Network for Earth project, which has developed and deployed a sustainable long-term data preservation and access network to ensure the preservation and access to multi-scale, multi-discipline, and multi-national environmental and biological science data (https://www.dataone.org/what-dataone (Michener et al. 2012. Methods: Personas for DataONE were developed based on data from surveys and interviews done by members of DataONE working groups along with sources such as usage scenarios for DataONE and the Data Conservancy project and the Purdue Data Curation Profiles (Witt et al. 2009. Results: A total of 11 personas were developed: five for various kinds of research scientists (e.g., at different career stages and using different types of data; a science data librarian; and five for secondary roles. Conclusion: Personas were found to be useful for helping developers and other project members to understand users and their needs. The developed DataONE personas may be useful for others trying to develop systems or programs for scientists involved in data sharing.

    Text-based plagiarism, or copying language from sources, has recently become an issue of growing concern in scientific publishing. Use of CrossCheck (a computational text-matching tool) by journals has sometimes exposed an unexpected amount of textual similarity between submissions and databases of scholarly literature. In this paper I provide an overview of the relevant literature, to examine how journal gatekeepers perceive textual appropriation, and how automated plagiarism-screening tools have been developed to detect text matching, with the technique now available for self-check of manuscripts before submission; I also discuss issues around English as an additional language (EAL) authors and in particular EAL novices being the typical offenders of textual borrowing. The final section of the paper proposes a few educational directions to take in tackling text-based plagiarism, highlighting the roles of the publishing industry, senior authors and English for academic purposes professionals.

    To describe the interests, preferred topics and learning in public health issues emerging from Chilean students with their participation in a science education experience. A qualitative exploratory study was conducted in 29 school research groups through the project Salud Con-Ciencia en tu Barrio, based on a content analysis of texts and narratives of students. Students prioritize the situation of abandoned animals, waste management, security and urban infrastructure, mainly. They view the role of social actors, the positive/negative impacts on the community, valuing the knowledge gained through observation neighborhoods and interaction with neighbors. Scientific inquiry school in the neighborhood context provides teaching strategies for the promotion of local health, develops basic notions of community health and motivation in students linked to the socio-environmental reality of their neighborhoods.

    In a relatively short interval for an emerging technology, nanotechnology has made a significant economic impact in numerous sectors including semiconductor manufacturing, catalysts, medicine, agriculture, and energy production. A part of the United States (US) government investment in basic research has been realized in the last two decades through the National Science Foundation (NSF), beginning with the nanoparticle research initiative in 1991 and continuing with support from the National Nanotechnology Initiative after fiscal year 2001. This paper has two main goals: (a) present a longitudinal analysis of the global nanotechnology development as reflected in the United States Patent and Trade Office (USPTO) patents and Web of Science (WoS) publications in nanoscale science and engineering (NSE) for the interval 1991-2012; and (b) identify the effect of basic research funded by NSF on both indicators. The interval has been separated into three parts for comparison purposes: 1991-2000, 2001-2010, and 2011-2012. The global trends of patents and scientific publications are presented. Bibliometric analysis, topic analysis, and citation network analysis methods are used to rank countries, institutions, technology subfields, and inventors contributing to nanotechnology development. We then, examined how these entities were affected by NSF funding and how they evolved over the past two decades. Results show that dedicated NSF funding used to support nanotechnology R and D was followed by an increased number of relevant patents and scientific publications, a greater diversity of technology topics, and a significant increase of citations. The NSF played important roles in the inventor community and served as a major contributor to numerous nanotechnology subfields.

    2010-01-01

    The current external environment of information work has undergone profound changes. The world competition in Military fields, the development of national economy and the applications of high-technologies put forward higher requirements to intelligence work. Under the environment of global information integration, 'eyes and ears' roles of nuclear scientific and technical information will be more highlighted. In this context, we believe that the way of nuclear sci-tech information development should be focused on comprehensive research and be based on the building of information resources and advanced information technology methods, forming an integrated service system with capabilities of rapid resources, decision support, information assurance and sustainable development. The goal of nuclear sci-tech information development should be to serve the development of nuclear power and the popularization and application of nuclear technology in the fields of national economy, to implement the strategy of 'integrated intelligence support', to ensure the formation of rapid response capability, to enhance capabilities of decision support and science and technology development guidance, to build digital information resources and to constantly promote the research on network collaboration. This paper analyzes the characteristics of nuclear sci-tech information under new competitive environment, describes the ideas and goals of its development and proposes the way to achieve these goals. In order to provide the information support and service with the characteristics of rapid response, high quality and high efficiency, the paper also puts forward that under the new environment, we should optimize the service system, extend service functions, transform service mode, speed up the transformation on intelligence work, adjust and optimize business content and structure, promote business process re-engineering, and pay equal attention to 'ensuring demands' and 'guiding the future

  18. A New Scientific Paradigm may be Needed to Finally Develop an HIV Vaccine.

    2015-01-01

    The bulk of current HIV vaccine research is conducted within the infectious disease paradigm that has been very successful in developing vaccines against many other viral diseases. Different HIV vaccine concepts, based on the induction of neutralizing antibodies and/or cell mediated immunity, have been developed and clinically tested over the last 30 years, resulting in a few small successes and many disappointments. As new scientific knowledge is obtained, HIV vaccine concepts are constantly modified with the hope that the newly introduced tweaks (or paradigm drifts) will provide the solution to one of the most difficult challenges that modern biomedical research is confronting. Efficacy trials have been critical in guiding HIV vaccine development. However, from the five phase III efficacy trials conducted to date, only one (RV144) resulted in modest efficacy. The results from RV144 were surprising in many ways, including the identified putative correlates of protection (or risk), which did not include neutralizing antibodies or cytotoxic T-cells. The solution to the HIV vaccine challenge may very well come from approaches based on the current paradigm. However, at the same time, out-of-the-paradigm ideas should be systematically explored to complement the current efforts. New mechanisms are needed to identify and support the innovative research that will hopefully accelerate the development of an urgently needed HIV vaccine.

    We introduce an entanglement branching operator to split a composite entanglement flow in a tensor network which is a promising theoretical tool for many-body systems. We can optimize an entanglement branching operator by solving a minimization problem based on squeezing operators. The entanglement branching is a new useful operation to manipulate a tensor network. For example, finding a particular entanglement structure by an entanglement branching operator, we can improve a higher-order tensor renormalization group method to catch a proper renormalization flow in a tensor network space. This new method yields a new type of tensor network states. The second example is a many-body decomposition of a tensor by using an entanglement branching operator. We can use it for a perfect disentangling among tensors. Applying a many-body decomposition recursively, we conceptually derive projected entangled pair states from quantum states that satisfy the area law of entanglement entropy.

  1. Meaningful Engagement in Scientific Practices: How Classroom Communities Develop Authentic Epistemologies for Science

    Science.gov (United States)

    Krist, Christina Rae

    Recent reforms in science education, based on decades of learning research, emphasize engaging students in science and engineering practices as the means to develop and refine disciplinary ideas. These reforms advocate an epistemic shift in how school science is done: from students learning about science ideas to students figuring out core science ideas. This shift is challenging to implement: how do we bring the goals and practices of a discipline into classroom communities in meaningful ways that go beyond simply following rote scientific procedures? In this dissertation, I investigate how classroom communities learn to engage meaningfully in scientific practices, characterizing their engagement as a process of epistemic learning. I take a situated perspective that defines learning as shifts in how members engage in communities of practice. I examine students' epistemic learning as a function of their participation in a classroom community of scientific practice along two dimensions: what they do, or the practical epistemic heuristics they use to guide how they build knowledge; and who they are, or how ownership and authorship of ideas is negotiated and affectively marked through interaction. I focus on a cohort of students as they move from 6th to 8 th grade. I analyze three science units, one from each grade level, to look at the epistemic heuristics implicit in student and teacher talk and how the use of those heuristics shifts over time. In addition, I examine one anomalous 8th grade class to look at how students and the teacher position themselves and each other with respect to the ideas in their classroom and how that positioning supports epistemic learning. Taken together, these analyses demonstrate how students' engagement in scientific practices evolves in terms of what they do and who they are in relation to the knowledge and ideas in their classroom over time. I propose a model for epistemic learning that articulates how classroom communities develop

    New approaches for teaching and assessing scientific inquiry and practices are essential for guiding students to make the informed decisions required of an increasingly complex and global society. The Science Skills approach described here guides students to develop an understanding of the experimental skills required to perform a scientific investigation. An individual teacher's investigation of the strategies and tools she designed to promote scientific inquiry in her classroom is outlined. This teacher-driven action research in the high school biology classroom presents a simple study design that allowed for reciprocal testing of two simultaneous treatments, one that aimed to guide students to use vocabulary to identify and describe different scientific practices they were using in their investigations-for example, hypothesizing, data analysis, or use of controls-and another that focused on scientific collaboration. A knowledge integration (KI) rubric was designed to measure how students integrated their ideas about the skills and practices necessary for scientific inquiry. KI scores revealed that student understanding of scientific inquiry increased significantly after receiving instruction and using assessment tools aimed at promoting development of specific inquiry skills. General strategies for doing classroom-based action research in a straightforward and practical way are discussed, as are implications for teaching and evaluating introductory life sciences courses at the undergraduate level.

    The Millennium Development Goals (MDGs) have contributed to unprecedented reductions in poverty and improvement in the lives of millions of men, women, and children in low- and middle-income countries. Yet, hundreds of millions of children under 5 y of age are not reaching their developmental potential. This article reviews the scientific basis for early childhood nutrition and child development interventions, the impact of integrated interventions on children’s linear growth and cognitive development, and implementation strategies for integrated nutrition and child development programs. Advances in brain science have documented that the origins of adult health and well-being are grounded in early childhood, from conception through age 24 mo (first 1000 d) and extending to age 5 y (second 1000 d). Young children with adequate nutrition, nurturant caregiving, and opportunities for early learning have the best chances of thriving. Evidence from adoption, experimental, and quasi-experimental studies has shown that stunting prevention is sensitive during the first 1000 d, and sensitivity to child development interventions extends through the second 1000 d. Cognitive development responds to interventions post–1000 d with effect sizes that are inversely associated with initial age and length of program exposure. Integrated interventions need governance structures that support integrated policies and programming, with attention to training, supervision, and monitoring. The MDGs have been replaced by the Sustainable Development Goals (SDGs), with targets for the next 15 y. Achievement of the SDGs depends on children receiving adequate nutrition, nurturant caregiving, and learning opportunities from conception through age 5. PMID:26875208

    NASA's High Performance Computing Portfolio in cooperation with its Modeling, Analysis, and Prediction program intends to make its climate and earth science models more accessible to a larger community. A key goal of this effort is to open the model development and validation process to the scientific community at large such that a natural selection process is enabled and results in a more efficient scientific process. One obstacle to others using NASA models is the complexity of the models and the difficulty in learning how to use them. This situation applies not only to scientists who regularly use these models but also non-typical users who may want to use the models such as scientists from different domains, policy makers, and teachers. Another obstacle to the use of these models is that access to high performance computing (HPC) accounts, from which the models are implemented, can be restrictive with long wait times in job queues and delays caused by an arduous process of obtaining an account, especially for foreign nationals. This project explores the utility of using desktop supercomputers in providing a complete ready-to-use toolkit of climate research products to investigators and on demand access to an HPC system. One objective of this work is to pre-package NASA and NOAA models so that new users will not have to spend significant time porting the models. In addition, the prepackaged toolkit will include tools, such as workflow, visualization, social networking web sites, and analysis tools, to assist users in running the models and analyzing the data. The system architecture to be developed will allow for automatic code updates for each user and an effective means with which to deal with data that are generated. We plan to investigate several desktop systems, but our work to date has focused on a Cray CX1. Currently, we are investigating the potential capabilities of several non-traditional development environments. While most NASA and NOAA models are

    Endosperm starch provides prime energy for cereal seedling growth. Cereal endosperm with repression of starch branching enzyme (SBE) has been widely studied for its high resistant starch content and health benefit. However, in barley and maize, the repression of SBE changes starch component and amylopectin structure which affects grain germination and seedling establishment. A high resistant starch rice line (TRS) has been developed through inhibiting SBEI/IIb, and its starch has very high resistance to in vitro hydrolysis and digestion. However, it is unclear whether the starch resists in situ degradation in seed and influences seedling growth after grain germination. In this study, TRS and its wild-type rice cultivar Te-qing (TQ) were used to investigate the seedling growth, starch property changes, and in situ starch degradation during seedling growth. The slow degradation of starch in TRS seed restrained the seedling growth. The starch components including amylose and amylopectin were simultaneously degraded in TQ seeds during seedling growth, but in TRS seeds, the amylose was degraded faster than amylopectin and the amylopectin long branch-chains with B-type crystallinity had high resistance to in situ degradation. TQ starch was gradually degraded from the proximal to distal region of embryo and from the outer to inner in endosperm. However, TRS endosperm contained polygonal, aggregate, elongated and hollow starch from inner to outer. The polygonal starch similar to TQ starch was completely degraded, and the other starches with long branch-chains of amylopectin and B-type crystallinity were degraded faster at the early stage of seedling growth but had high resistance to in situ degradation during TRS seedling growth. The B-type crystallinity and long branch-chains of amylopectin in TRS seed had high resistance to in situ degradation, which inhibited TRS seedling growth.

    In nuclear power plants, vibrational stress of piping is measured to prevent its fatigue failures. Easier handling and more efficient performance is desirable for the measurement of vibrational stress. The authors have proposed a method to measure vibrational stress using optical contactless displacement sensors, and have developed a device based on the method. In addition, they downsized the device and improved the method to allow its use for measurements even in narrow spaces in the plants. In this study, vibrational experiment using branch pipes and the device was conducted to confirm the measurement accuracy of the improved method. It was found that the improved method have sufficient accuracy for screening to evaluate the vibrational stress. It was also found that this measurement method was thought to be susceptible to the vibration of main pipe. So a technique was proposed to improve the accuracy of the measurement in this paper.

    Full Text Available The professional blog is a weblog that on the whole meets the requirements of scientific publication. In my opinion it bear a resemblance to digital notice board, where the competent specialists of the given branch of science can place their ideas, questions, possible solutions and can raise problems. Its most important function can be collectivization of the knowledge. In this article I am going to examine the characteristics of the scientific blog as a genre. Conventional learning counts as a rather solitary activity. If the students have access to the materials of each other and of the teacher, their sense of solitude diminishes and this model is also closer to the constructivist approach that features the way most people think and learn. Learning does not mean passively collecting tiny pieces of knowledge; it much more esembles ‘spinning a conceptual net’ which is made up by the experiences and observations of the individual. With the spreading of the Internet more universities and colleges worldwide gave a try to on-line educational methods, but the most efficient one has not been found yet. The publication of the curriculum (the material of the lectures and the handling of the electronic mails are not sufficient; much more is needed for collaborative learning. Our scholastic scientific blog can be a sufficient field for the start of a knowledge-building process based on cooperation. In the Rocard-report can be read that for the future of Europe it is crucial to develop the education of the natural sciences, and for this it isnecessary to act on local, regional, national and EU-level. To the educational processes should be involved beyond the traditional actors (child, parent, teacher also others (scientists, professionals, universities, local institutions, the actors of the economic sphere, etc.. The scholastic scientific blog answer the purposes, as a collaborative knowledge-sharing forum.

    To assess whether the content of Scientific Advice (SA) questions addressed to a national drug regulatory agency is associated with company size. This may help to increase understanding about the knowledge, strategic, and regulatory gaps companies face during drug development. A cross-sectional analysis was performed of SA provided by the Dutch Medicines Evaluation Board (MEB) in 2006-2008. Definition of company size was based on ranking by total revenues (Scrip's Pharmaceutical Company League Tables 2008). The content of each SA question was scored according to predefined domains (quality, nonclinical, clinical, regulatory, and product information), their subdomains (e.g., efficacy), and a selection of additional content variables (e.g., endpoints, choice of active comparator). In total, 201 SA documents including 1,087 questions could be identified. Small, medium-sized, and large companies asked for SA 110 (54.7%), 40 (19.9%), and 51 (25.4%) times, respectively. Clinical questions were asked most often (65.9%), mainly including efficacy (33.2%) and safety questions (24.0%). The most frequent topics were overall efficacy and safety strategy. Small companies asked quality and nonclinical questions more often (P companies (P = 0.004). Small companies asked significantly more clinical questions about pharmacokinetics, including bioequivalence, than medium-sized and large companies (P Company size is associated with the content of SA questions.

    Full Text Available Objective: the scientific basis of priority directions of the health care development for cardiac patients in city according to public health system. Improving medical and demographic situation, increasing the availability and quality of care to all segments of the population is the priority task of modern health care system in Ukraine. Various aspects of population health due to diseases of the cardiovascular system and the issues of improving public health system and the system of cardiac care for the population, is the subject of many years researches. Cardiovascular diseases are leading causes of premature death, disability, temporary disability. According to the experience of developed countries in recent decades, the prevalence of this pathology and the severity of the harm to public health can reduce significantly in case of effective organization of medical-diagnostic process and prevention system. Specialized in patient care for patients suffering from cardiovascular diseases, is very expensive. At the same time, the number of patients with such pathology is high enough in ambulatory practice. Among them, special attention should be paid to those patients, who require daily monitoring, but do not require the round-the-clock stationary mode. The organization of inpatient forms of medical care for this category of patients is a very urgent task. Equally important are the training of personnel for the cardiology service, the sustainability of human resources, economic motivation, which ensures high quality, the effectiveness of complex labor processes.

    Scientific communication, both written and oral, is the cornerstone of success in biomedical research, yet formal instruction is rarely provided. Trainees with little exposure to standard academic English may find developing scientific communication skills challenging. In this exploratory, hypothesis-generating qualitative study, the authors examined the process by which mentored junior researchers learn scientific communication skills, their feelings about the challenges, and their mentor's role in the process. In 2010, the authors conducted semistructured focus groups and interviews to explore research trainees' and faculty mentors' perceptions and practices regarding scientific communication skills development, as part of the development phase of a larger quantitative study. The facilitator took detailed notes and verified their accuracy with participants during the sessions; a second member of the research team observed and verified the recorded notes. Three coders performed a thematic analysis, and the other authors reviewed it. Forty-three trainees and 50 mentors participated. Trainees and mentors had diverging views on the role of mentoring in fostering communication skills development. Trainees expressed varying levels of self-confidence but considerable angst. Mentors felt that most trainees have low self-confidence. Trainees expressed interest in learning scientific communication skills, but mentors reported that some trainees were insufficiently motivated and seemed resistant to guidance. Both groups agreed that trainees found mentors' feedback difficult to accept. The degree of distress, dissatisfaction, and lack of mutual understanding between mentors and trainees was striking. These themes have important implications for best practices and resource development.

Methods The CBPR framework was applied to help maximize the development of the intervention and the public health impact of the studies, while enhancing the capabilities of the social service sector partners. Results Four academic-community research teams explored the process of designing and implementing randomized controlled trials in the community. In addition to the expected cultural barriers between teams of academics and community practitioners, with their different outlooks, concerns and languages, the team navigated issues in utilizing the principles of CBPR unique to this Chinese culture. Eventually the team developed tools for adaptation, such as an emphasis on building the relationship while respecting role delineation and an iterative process of defining the non-negotiable parameters of research design while maintaining scientific rigor. Lessons learned include the risk of underemphasizing the size of the operational and skills shift between usual agency practices and research studies, the importance of minimizing non-negotiable parameters in implementing rigorous research designs in the community, and the need to view community capacity enhancement as a long term process. Conclusions The four pilot studies under the FAMILY Project demonstrated that nuanced design adaptations, such as wait list controls and shorter assessments, better served the needs of the community and led to the successful development and vigorous evaluation of a series of preventive, family-oriented interventions in the Chinese culture of Hong Kong.

    2002-06-01

    Full Text Available This paper is a research and journalistic work that summarizes and synthesizes the scientific development of the physiology of plants in the American tropics, also known as the Neotropics. It contains the contributions of numerous biologists interested in the physiology of tropical plants. The fabulous structural and functional diversity of tropical forests is still the major driver of research in this field. Classical physiological work involving tropical plants, such as the discovery of C4 photosynthesis in sugarcane, is invoked to exemplify the historical and current importance of physiological research in the tropics, and its applications in agriculture, forestry and conservation. An historical background describing the early and more recent development of a tradition on the physiological study of tropical plants is followed by a summary of the research conducted on the physiology of tropical crops. Common areas of interest and influence between the fields of crop physiology and plant ecophysiology are identified and exemplified with problems on the environmental physiology of crops like coffee and cassava. The physiology of tropical forest plants is discussed in terms of its contributions to general plant physiological knowledge in areas such as photosynthetic metabolism and plant water relations. Despite the impressive technical advances achieved during the past decade, the importance of continuous development of appropriate instrumentation to study and measure the physiology of plants in situ is stressed. Although the basic metabolic processes that underlie the mechanisms of plant responses to the environment are probably highly conserved and qualitatively similar among tropical and temperate plants, it is also apparent that tropical plants exhibit metabolic peculiarities. These include aspects of photosynthetic metabolism, phloem transport physiology, sensitivity to low temperatures, reproduction, responses to climatic seasonality, and a

    National Epidemiological Institute (National Institute of Hygiene, from 7th September 1923) was established in 1918 in Warsaw and acted at national level. Its actions in the field of diseases combat were supported by bacteriological stations and vaccine production in voivodeship cities, which were taken charge of by the state, and names "National Epidemiological Institutes". According to the ministers resolution from 6th July 1921,Epidemiological Institutes were merged to National Central Epidemiological Institutes (PZH), the epidemiological institutes outside Warsaw were named branches, which were to be located in every voivodeship city, according to the initial organizational resolutions. There were country branches of NCEI in: Cracow, Lwów, Lódź, Toruń, Lublin, and Wilno in the period 1919-1923. New branches in Poznań (1925), Gdynia(1934), Katowice (Voivodeship Institute of Hygiene (1936), Luck (1937), Stanisławów (1937), Kielce(1938), and Brześć/Bug (Municipal Station acting as branch of National Central Epidemiological Institute. Branches were subordinated to NCEI-PZH) in Warsaw where action plans and unified research and diagnostic method were established and annual meeting of the country branches managers took place. All branches cooperated with hospitals, national health services, district general practitioners and administration structure in control of infectious diseases. In 1938, the post of branch inspector was established, the first of whom was Feliks Przesmycki PhD. Branches cooperated also with University of Cracow, University of Lwów and University of Wilno. In 1935, National Institutes of Food Research was incorporated in PZH, Water Department was established, and these areas of activity began to develop in the branches accordingly. In 1938 there were 13 branches of PZH, and each had three divisions: bacteriological, food research and water research. Three branches in Cracow, Kielce and Lublin worked during World War II under German

    The mammalian lung develops through branching morphogenesis. Two primary forms of branching, which occur in order, in the lung have been identified: tip bifurcation and side branching. However, the mechanisms of lung branching morphogenesis remain to be explored. In our previous study, a biological mechanism was presented for lung branching pattern formation through a branching model. Here, we provide a mathematical mechanism underlying the branching patterns. By decoupling the branching model, we demonstrated the existence of Turing instability. We performed Turing instability analysis to reveal the mathematical mechanism of the branching patterns. Our simulation results show that the Turing patterns underlying the branching patterns are spot patterns that exhibit high local morphogen concentration. The high local morphogen concentration induces the growth of branching. Furthermore, we found that the sparse spot patterns underlie the tip bifurcation patterns, while the dense spot patterns underlies the side branching patterns. The dispersion relation analysis shows that the Turing wavelength affects the branching structure. As the wavelength decreases, the spot patterns change from sparse to dense, the rate of tip bifurcation decreases and side branching eventually occurs instead. In the process of transformation, there may exists hybrid branching that mixes tip bifurcation and side branching. Since experimental studies have reported that branching mode switching from side branching to tip bifurcation in the lung is under genetic control, our simulation results suggest that genes control the switch of the branching mode by regulating the Turing wavelength. Our results provide a novel insight into and understanding of the formation of branching patterns in the lung and other biological systems.

    Heuristic definition of the Feynman continual integral over branching trajectories is suggested which makes it possible to obtain in the closed form the solution of the Cauchy problem for the model Hartree equation. A number of properties of the solution is derived from an integral representation. In particular, the quasiclassical asymptotics, exact solution in the gaussian case and perturbation theory series are described. The existence theorem for the simpliest continual integral over branching trajectories is proved [ru

    Full Text Available Phelipanche ramosa is a parasitic plant that infects numerous crops worldwide. In Western Europe it recently expanded to a new host crop, oilseed rape, in which it can cause severe yield losses. We developed 13 microsatellite markers for P. ramosa using next-generation 454 sequencing data. The polymorphism at each locus was assessed in a sample of 96 individuals collected in France within 6 fields cultivated with tobacco, hemp or oilseed rape. Two loci were monomorphic. At the other 11 loci, the number of alleles and the expected heterozygosity ranged from 3 to 6 and from 0.31 to 0.60, respectively. Genetic diversity within each cultivated field was very low. The host crop from which individuals were collected was the key factor structuring genetic variation. Individuals collected on oilseed rape were strongly differentiated from individuals collected on hemp or tobacco, which suggests that P. ramosa infecting oilseed rape forms a genetically diverged race. The microsatellites we developed will be useful for population genetics studies and for elucidating host-associated genetic divergence in P. ramosa.

    With respect to the question of supersymmetry breaking, there are three branches of the flux landscape. On one of these, if one requires small cosmological constant, supersymmetry breaking is predominantly at the fundamental scale; on another, the distribution is roughly flat on a logarithmic scale; on the third, the preponderance of vacua are at very low scale. A priori, as we will explain, one can say little about the first branch. The vast majority of these states are not accessible even to crude, approximate analysis. On the other two branches one can hope to do better. But as a result of the lack of access to branch one, and our poor understanding of cosmology, we can at best conjecture about whether string theory predicts low energy supersymmetry or not. If we hypothesize that are on branch two or three, distinctive predictions may be possible. We comment of the status of naturalness within the landscape, deriving, for example, the statistics of the first branch from simple effective field theory reasoning

    The potential of computer-based assessments for capturing complex learning outcomes has been discussed; however, relatively little is understood about how to leverage such potential for summative and accountability purposes. The aim of this study is to develop and validate a multimedia-based assessment of scientific inquiry abilities (MASIA) to cover a more comprehensive construct of inquiry abilities and target secondary school students in different grades while this potential is leveraged. We implemented five steps derived from the construct modeling approach to design MASIA. During the implementation, multiple sources of evidence were collected in the steps of pilot testing and Rasch modeling to support the validity of MASIA. Particularly, through the participation of 1,066 8th and 11th graders, MASIA showed satisfactory psychometric properties to discriminate students with different levels of inquiry abilities in 101 items in 29 tasks when Rasch models were applied. Additionally, the Wright map indicated that MASIA offered accurate information about students' inquiry abilities because of the comparability of the distributions of student abilities and item difficulties. The analysis results also suggested that MASIA offered precise measures of inquiry abilities when the components (questioning, experimenting, analyzing, and explaining) were regarded as a coherent construct. Finally, the increased mean difficulty thresholds of item responses along with three performance levels across all sub-abilities supported the alignment between our scoring rubrics and our inquiry framework. Together with other sources of validity in the pilot testing, the results offered evidence to support the validity of MASIA.

    The roots of transcultural psychiatry in Germany can be traced back to Emil Kraepelin, who made the first culturally comparative observations on mental disorders in Southeast Asia at the start of the 20th century. Since the beginning of the 1970s, contributors to the literature of transcultural psychiatry in Germany have been predominantly concerned with the mental health of migrant workers from Mediterranean countries, particularly the practical difficulties and therapeutic implications of inpatient psychiatric treatment of these migrant groups. The inauguration of the Section on Transcultural Psychiatry of the German Association for Psychiatry and Psychotherapy 20 years ago reflected an increasing scientific interest in this topic. In addition to the psychic impact of migration, research into transcultural care is currently focused on disparities in the utilization of health care and conjectured barriers to access to health and mental health care among migrants. Furthermore, studies based on epidemiological approaches have been carried out in order to resolve the question of whether migrants are as affected by mental disorders as the ethnic German population, and which issues contribute to the so-called "healthy migrant" effect. Other topics that have been explored in the last 10 years are the particular psychosocial situation of asylum seekers and refugees in Germany, and the effects of inadequate integration and discrimination on their mental health. In summary, after a short historical and theoretical overview, this article reviews the current major themes in transcultural research in German contemporary psychiatry, and concludes with an overview of future developments in this field.

    The main objective is to study the communications dimensions of China's contribution to the discovery of high-Tc superconductors. Chinese researchers of the field were compared with non-Chinese superconductivity scientists from developed countries to reveal similarities and differences in the formal as well as the informal domains of scholarly communication. 240 documents highly cited in a manually created Chinese data base and in Science Citation Index for the period of 1987-89 were examined to delineate the formal structure of communication in the area. Noteworthy similarities, e.g., similar cited cores, identical publication sources, and comparable intellectual structures of cocitation data, were found in formal communication between Chinese and non-Chinese scientists. Nevertheless, differences were also located in regard to citedness, timeliness and direction of communication. Findings reflect the role Chinese scientists played in the discovery of high-Tc superconductors. Chinese researchers overall did better in the formal domain than in the informal realm of scientific communication. Informal communication with scientists from advanced nations appears to be a very weak element in China's endeavors of searching for high-Tc superconductors

    We seek to develop a prototype software analytical tool to augment FDA regulatory reviewers' capacity to harness scientific literature reports in PubMed/MEDLINE for pharmacovigilance and adverse drug event (ADE) safety signal detection. We also aim to gather feedback through usability testing to assess design, performance, and user satisfaction with the tool. A prototype, open source, web-based, software analytical tool generated statistical disproportionality data mining signal scores and dynamic visual analytics for ADE safety signal detection and management. We leveraged Medical Subject Heading (MeSH) indexing terms assigned to published citations in PubMed/MEDLINE to generate candidate drug-adverse event pairs for quantitative data mining. Six FDA regulatory reviewers participated in usability testing by employing the tool as part of their ongoing real-life pharmacovigilance activities to provide subjective feedback on its practical impact, added value, and fitness for use. All usability test participants cited the tool's ease of learning, ease of use, and generation of quantitative ADE safety signals, some of which corresponded to known established adverse drug reactions. Potential concerns included the comparability of the tool's automated literature search relative to a manual 'all fields' PubMed search, missing drugs and adverse event terms, interpretation of signal scores, and integration with existing computer-based analytical tools. Usability testing demonstrated that this novel tool can automate the detection of ADE safety signals from published literature reports. Various mitigation strategies are described to foster improvements in design, productivity, and end user satisfaction.

    Plants need to accurately adjust their development after germination in the underground darkness to ensure survival of the seedling, both in the dark and in the light upon reaching the soil surface. Recent studies have established that the photoreceptors phytochromes and the bHLH phytochrome interacting factors PIFs regulate seedling development to adjust it to the prevailing light environment during post-germinative growth. However, complete understanding of the downstream regulatory network implementing these developmental responses is still lacking. In a recent work, published in The Plant Cell, we report a subset of PIF3-regulated genes in dark-grown seedlings that we have named MIDAs (MISREGULATED IN DARK). Analysis of their functional relevance using mutants showed that four of them present phenotypic alterations in the dark, and that each affected a particular facet of seedling development, suggesting organ-specific branching in the signal that PIF3 relays downstream. Furthermore, our results also showed an altered response to light in seedlings with an impaired PIF3/MIDA regulatory network, indicating that these factors might also be essential to initiate and optimize the developmental adjustment of the seedling to the light environment.

    Ethics, a branch of philosophy, has a place in the regulatory framework of human subjects research. Sometimes, however, ethical concepts and arguments play a more central role in scientific activity. This can happen, for example, when violations of research norms are also ethical violations. In such a situation, ethical arguments can be marshaled to improve the quality of the scientific research. I explore two different examples in which philosophers and scientists have used ethical arguments to plead for epistemological improvements in the conduct of research. The first example deals with research dishonesty in pharmaceutical development. The second example is concerned with neuropsychological research using fMRI technology.

    2018-04-01

    Full Text Available In the last decades in developing countries, the tourism sector has been immersed in an intense process of strengthening the participation of local communities through the so-called community tourism initiatives, whose main objective is to improve the quality of life of the inhabitants of host communities, ensuring the subsistence of traditional culture. Its growing momentum as a means for sustainable tourism and a strategy for social development has generated a large amount of academic literature, and it is necessary to analyze its presence in the main multidisciplinary databases. Thus, the main purpose of our article is to show the current state of scientific production on community tourism through a bibliometric comparative study of the documents indexed in the WoS and Scopus databases, dealing with aspects such as their coverage, correlation between both bases, overlapping of documents and journals, growth, dispersion or concentration of articles, among others. For this purpose, and by means of an advanced search by terms, a representative set of 115 articles in WoS and 185 in Scopus were selected, with the time limit set in 2017. These form the ad-hoc basis of the analysis. In view of the results, it is concluded that, although WoS and Scopus databases differ in terms of scope, volume of data, and coverage policies, both information systems are complementary but not exclusive. Although the documents and the results of their analysis are in many aspects similar, Scopus has a better coverage in the specific area of community tourism due to collecting a greater number of articles, journals and signatures, and its articles receiving a greater number of citations.

  19. Does attainment of Piaget's formal operational level of cognitive development predict student understanding of scientific models?

    Science.gov (United States)

    Lahti, Richard Dennis, II

    Knowledge of scientific models and their uses is a concept that has become a key benchmark in many of the science standards of the past 30 years, including the proposed Next Generation Science Standards. Knowledge of models is linked to other important nature of science concepts such as theory change which are also rising in prominence in newer standards. Effective methods of instruction will need to be developed to enable students to achieve these standards. The literature reveals an inconsistent history of success with modeling education. These same studies point to a possible cognitive development component which might explain why some students succeeded and others failed. An environmental science course, rich in modeling experiences, was used to test both the extent to which knowledge of models and modeling could be improved over the course of one semester, and more importantly, to identify if cognitive ability was related to this improvement. In addition, nature of science knowledge, particularly related to theories and theory change, was also examined. Pretest and posttest results on modeling (SUMS) and nature of science (SUSSI), as well as data from the modeling activities themselves, was collected. Cognitive ability was measured (CTSR) as a covariate. Students' gain in six of seven categories of modeling knowledge was at least medium (Cohen's d >.5) and moderately correlated to CTSR for two of seven categories. Nature of science gains were smaller, although more strongly correlated with CTSR. Student success at creating a model was related to CTSR, significantly in three of five sub-categories. These results suggest that explicit, reflective experience with models can increase student knowledge of models and modeling (although higher cognitive ability students may have more success), but successfully creating models may depend more heavily on cognitive ability. This finding in particular has implications in the grade placement of modeling standards and

    The Dietary Guidelines for Americans (DGA) is published every 5 y jointly by the Department of Health and Human Services (HHS) and the USDA and provides a framework for US-based food and nutrition programs, health promotion and disease prevention initiatives, and research priorities. Summarized in this report are the methods, major conclusions, and recommendations of the Scientific Report of the 2015 US Dietary Guidelines Advisory Committee (DGAC). Early in the process, the DGAC developed a conceptual model and formulated questions to examine nutritional risk and determinants and impact of dietary patterns in relation to numerous health outcomes among individuals aged ≥2 y. As detailed in the report, an expansive, transparent, and comprehensive process was used to address each question, with multiple opportunities for public input included. Consensus was reached on all DGAC's findings, including each conclusion and recommendation, and the entire report. When research questions were answered by original systematic literature reviews and/or with existing, high-quality expert reports, the quality and strength of the evidence was formally graded. The report was organized around the following 5 themes: 1) food and nutrient intakes and health: current status and trends; 2) dietary patterns, foods and nutrients, and health outcomes; 3) diet and physical activity behavior change; 4) food and physical activity environments; and 5) food sustainability and food safety. The following 3 cross-cutting topics were addressed: 1) sodium, 2) saturated fat, and 3) added sugars. Physical activity recommendations from recent expert reports were endorsed. The overall quality of the American diet was assessed to identify overconsumed and underconsumed nutrients of public health concern. Common food characteristics of healthy dietary patterns were determined. Features of effective interventions to change individual and population diet and physical activity behaviors in clinical, public

  1. Development of sustainable water treatment technology using scientifically based calculated indexes of source water quality indicators

    2017-10-01

    Full Text Available The article describes selection process of sustainable technological process flow chart for water treatment procedure developed on scientifically based calculated indexes of quality indicators for water supplied to water treatment facilities. In accordance with the previously calculated values of the indicators of the source water quality, the main purification facilities are selected. A more sustainable flow chart for the modern water quality of the Seversky Donets-Donbass channel is a two-stage filtering with contact prefilters and high-rate filters. The article proposes a set of measures to reduce such an indicator of water quality as permanganate oxidation. The most suitable for these purposes is sorption purification using granular activated carbon for water filtering. The increased water hardness is also quite topical. The method of ion exchange on sodium cation filters was chosen to reduce the water hardness. We also evaluated the reagents for decontamination of water. As a result, sodium hypochlorite is selected for treatment of water, which has several advantages over chlorine and retains the necessary aftereffect, unlike ozone. A technological flow chart with two-stage purification on contact prefilters and two-layer high-rate filters (granular activated carbon - quartz sand with disinfection of sodium hypochlorite and softening of a part of water on sodium-cation exchangers filters is proposed. This technological flow chart of purification with any fluctuations in the quality of the source water is able to provide purified water that meets the requirements of the current sanitary-hygienic standards. In accordance with the developed flow chart, guidelines and activities for the reconstruction of the existing Makeevka Filtering Station were identified. The recommended flow chart uses more compact and less costly facilities, as well as additional measures to reduce those water quality indicators, the values of which previously were in

    XIX International Scientific Symposium in honor of Academician M.A. Usov ''Problems of Geology and Subsurface Development'' (for students and young scientists) was organized under the guidance of the Ministry of Education and Science of the Russian Federation and the Russian Foundation for Fundamental Research within the National Research Tomsk Polytechnic University (NR TPU). TPU is one of the oldest technical higher education institutions in Russia, training specialists in the domain of geoscience and enhancing their further research in this area. The Institute of Natural Resources, National Research Tomsk Polytechnic University (INR TPU) was chosen to hold the International Scientific Symposium. In 2015 the Institute of Natural Resources celebrated its 114th anniversary. It was founded by V.A. Obruchev in 1901, first Siberian geologist, member of USSR Academy of Sciences, Hero of Socialist Labor, and first Laureate of the Lenin Prize. He was recognized as a prominent scientist in the area of geology all over the world. INR is the first institute of geological education and geosciences in Asian Russia. Even today the Siberian Mining and Geological School, established by V.A. Obruchev and M.A. Usov, has retained its significance in the discovery, exploration and development of mineral resources not only in Siberia, the Far East and North-East of Russia, but also in Central Asia. There are numerous outstanding scientists and engineers among alumni of The Institute of Natural Resources. The institute is proud of such outstanding people as: M.A. Usov, student and first postgraduate of V.A. Obruchev, first professor and academician in Siberia, whose name is associated with the mining industry in Siberia; Academician K.I. Satpaev, founder and first president of the Academy of Sciences of Kazakhstan; Professor N.N. Urvantsev, discoverer of the unique Norilsk ore deposits in the North of East Siberia and Professor M.K.

    The aim of this study is to review the name of the branches, to review the classification of the branching pattern, and to clarify a presence percentage of each branch of the facial artery, systematically. In a PubMed search, the search terms "facial," AND "artery," AND "classification OR variant OR pattern" were used. The IBM SPSS Statistics 20 system was used for statistical analysis. Among the 500 titles, 18 articles were selected and reviewed systematically. Most of the articles focused on "classification" according to the "terminal branch." Several authors classified the facial artery according to their terminal branches. Most of them, however, did not describe the definition of "terminal branch." There were confusions within the classifications. When the inferior labial artery was absent, 3 different types were used. The "alar branch" or "nasal branch" was used instead of the "lateral nasal branch." The angular branch was used to refer to several different branches. The presence as a percentage of each branch according to the branches in Gray's Anatomy (premasseteric, inferior labial, superior labial, lateral nasal, and angular) varied. No branch was used with 100% consistency. The superior labial branch was most frequently cited (95.7%, 382 arteries in 399 hemifaces). The angular branch (53.9%, 219 arteries in 406 hemifaces) and the premasseteric branch were least frequently cited (53.8%, 43 arteries in 80 hemifaces). There were significant differences among each of the 5 branches (P < 0.05) except between the angular branch and the premasseteric branch and between the superior labial branch and the inferior labial branch. The authors believe identifying the presence percentage of each branch will be helpful for surgical procedures.

    Over the past several years, AECL has embarked on a comprehensive program to develop, qualify and support its key safety and licensing codes, and to make executable versions of these codes available to the international nuclear community. To this end, we have instituted a company-wide Software Quality Assurance (SQA) Program for Analytical, Scientific and Design Computer Programs to ensure that the design, development, maintenance, modification, procurement and use of computer codes within AECL is consistent with today's quality assurance standards. In addition, we have established a comprehensive Code Validation Project (CVP) with the goal of qualifying AECL's 'front-line' safety and licensing codes by 2001 December. The outcome of this initiative will be qualified codes, which are properly verified and validated for the expected range of applications, with associated statements of accuracy and uncertainty for each application. The code qualification program, based on the CSA N286.7 standard, is intended to ensure (1) that errors are not introduced into safety analyses because of deficiencies in the software, (2) that an auditable documentation base is assembled that demonstrates to the regulator that the codes are of acceptable quality, and (3) that these codes are formally qualified for their intended applications. Because AECL and the Canadian nuclear utilities (i.e., Ontario Power Generation, Bruce Power, Hydro Quebec and New Brunswick Power) generally use the same safety and licensing codes, the nuclear industry in Canada has agreed to work cooperatively together towards the development, qualification and maintenance of a common set of analysis tools, referred to as the Industry Standard Toolset (IST). This paper provides an overview of the AECL Software Quality Assurance Program and the Code Validation Project, and their associated linkages to the Canadian nuclear community's Industry Standard Toolset initiative to cooperatively qualify and support commonly

    A multidisciplinary faculty committee designed a curriculum to shape biomedical graduate students into researchers with a high commitment to professionalism and social responsibility and to provide students with tools to navigate complex, rapidly evolving academic and societal environments with a strong ethical commitment. The curriculum used problem-based learning (PBL), because it is active and learner-centred and focuses on skill and process development. Two courses were developed: Scientific Professionalism: Scientific Integrity addressed discipline-specific and broad professional norms and obligations for the ethical practice of science and responsible conduct of research (RCR). Scientific Professionalism: Bioethics and Social Responsibility focused on current ethical and bioethical issues within the scientific profession, and implications of research for society. Each small-group session examined case scenarios that included: (1) learning objectives for professional norms and obligations; (2) key ethical issues and philosophies within each topic area; (3) one or more of the RCR instructional areas; and (4) at least one type of moral reflection. Cases emphasised professional standards, obligations and underlying philosophies for the ethical practice of science, competing interests of stakeholders and oversight of science (internal and external). To our knowledge, this is the first use of a longitudinal, multi-semester PBL course to teach scientific integrity and professionalism. Both faculty and students endorsed the active learning approach for these topics, in contrast to a compliance-based approach that emphasises learning rules and regulations.

    There are many daunting challenges for companies who wish to bring novel drugs to market. The information complexity around potential drug targets has increased greatly with the introduction of microarrays, high-throughput screening and other technological advances over the past decade, but has not yet fundamentally increased our understanding of how to modify a disease with pharmaceuticals. Further, the bar has been raised in getting a successful drug to market as just being new is no longer enough: the drug must demonstrate improved performance compared with the ever increasing generic pharmacopeia to gain support from payers and government authorities. In addition, partly as a consequence of a climate of concern regarding the safety of drugs, regulatory authorities have approved fewer new molecular entities compared to historical norms over the past few years. To overcome these challenges, the pharmaceutical industry must fully embrace information technology to bring better understood compounds to market. An important first step in addressing an unmet medical need is in understanding the disease and identifying the physiological target(s) to be modulated by the drug. Deciding which targets to pursue for a given disease requires a multidisciplinary effort that integrates heterogeneous data from many sources, including genetic variations of populations, changes in gene expression and biochemical assays. The Life Science Grid was developed to provide a flexible framework to integrate such diverse biological, chemical and disease information to help scientists make better-informed decisions. The Life Science Grid has been used to rapidly and effectively integrate scientific information in the pharmaceutical industry and has been placed in the open source community to foster collaboration in the life sciences community.

    One of the main aims of the IAEA is to foster the exchange of scientific and technical information and one of the main ways of doing this is to convene international scientific meetings. They range from large international conferences bringing together several hundred scientists, smaller symposia attended by an average of 150 to 250 participants and seminars designed to instruct rather than inform, to smaller panels and study groups of 10 to 30 experts brought together to advise on a particular programme or to develop a set of regulations. The topics of these meetings cover every part of the Agency's activities and form a backbone of many of its programmes. (author)

    Understanding of science instructional leading to the formation of student scientific literacy, seems not yet fully understood well by science teachers. Because of this, certainly needs to be reformed because science literacy is a major goal in science education for science education reform. Efforts of development science literacy can be done by help students develop an information conception of the Nature of Science (NoS) and apply inquiry approach. It is expected that students’ science literacy can develop more optimal by combining NoS within inquiry approach. The purpose of this research is to produce scientific literacy development model of NoS within inquiry-based learning. The preparation of learning tools will be maked through Research and Development (R & D) following the 4-D model (Define, Design, Develop, and Disseminate) and Borg & Gall. This study is a follow-up of preliminary research results about the inquiry profile of junior high school students indicating that most categories are quite good. The design of the model NoS within inquiry approach for developing scientific literacy is using MER Model in development educational reconstruction. This research will still proceed to the next stage that is Develop.

    2016-03-01

    Engagement in purposeful problem solving involving social science content was sufficient to develop a key set of inquiry skills in low-performing middle school students from an academically and economically disadvantaged urban public school population, with this skill transferring to a more traditional written scientific thinking assessment instrument 3weeks later. Students only observing their peers' activity or not participating at all failed to show these gains. Implications are addressed with regard to the mastery of scientific thinking skills among academically disadvantaged students. Also addressed are the efficacy of problem-based learning and the limits of observational learning. Copyright © 2015 Elsevier Inc. All rights reserved.

    Integrated measures of crustal deformation provide valuable insight about tectonic and human-induced processes for scientists and educators alike. UNAVCO in conjunction with EarthScope initiated a series of short courses for researchers to learn the processing and interpretation of data from new technologies such as high precision GPS, Strainmeter, InSar and LiDAR that provide deformation information relevant to many geoscience sub-disciplines. Intensive short courses of a few days and the widespread availability of processed data through large projects such as EarthScope and GEON enable more geoscientists to incorporate these data into diverse projects. Characteristics of the UNAVCO Short Course Series, reaching over 400 participants since 2005, include having short course faculty who have pioneered development of each technology; open web-access to course materials; processing software installed on class-ready computers; no course fees; scholarships for students, post-doctoral fellows, and emerging faculty when needed; formative evaluation of the courses; community-based decisions on topics; and recruitment of participants across relevant geoscience disciplines. In 2009, when EarthScope airborne LiDAR data became available to the public through OpenTopographhy, teaching materials were provided to these researchers to incorporate the latest technologies into teaching. Multiple data sets across technologies have been developed with instructions on how to access the various data sets and incorporate them into geological problem sets. Courses in GPS, airborne LiDAR, strainmeter, and InSAR concentrate on data processing with examples of various geoscience applications. Ground-based LiDAR courses also include data acquisition. Google Earth is used to integrate various forms of data in educational applications. Various types of EarthScope data can now be used by a variety of geoscientists, and the number of scientists who have the skills and tools to use these various

  19. How are scientific thinking skills best developed? Direct instruction vs. inquiry practice

    Science.gov (United States)

    Dean, David Worth, Jr.

    Despite its support and adoption by most major scientific and educational organizations, some researchers have questioned whether inquiry learning is indeed the best method for acquiring the skills of inquiry. Klahr and colleagues have investigated the development of the control of variables strategy, or controlled comparison (CC), and claim that a brief session of direct instruction, characterized by explicit training of CC, as opposed to allowing children to discover CC through inquiry learning, is sufficient for acquisition, maintenance, and transfer of this core aspect of inquiry. Kuhn and colleagues, however, argue that direct instruction may be insufficient for development of the metastrategic level of understanding necessary to adequately maintain and transfer inquiry skills. In the present study, I attempt to identify the intervention most effective in supporting acquisition, maintenance, and transfer of these skills. Three groups of students received either a direct instruction session followed by standard classroom instruction (DI-only), an introductory session (without direct instruction) followed by practice sessions only (PR-only), or a direct instruction session followed by practice sessions (DI+PR). Practice sessions involved the use of a computer-based inquiry task requiring students to investigate the effects of five potential causal variables on an outcome. The two practice groups worked with this program during 12 sessions over nine weeks. They worked with structurally identical software programs during five weekly maintenance sessions. During this time, the DI-only group received standard classroom instruction. All groups were assessed on familiar and unfamiliar computer-based inquiry tasks at the conclusion of intervention (immediate assessment) and maintenance sessions (delayed assessment). Students in the two practice groups demonstrated improvement in an integrative measure of inquiry skill (valid intent, valid strategy, valid inference, and

  2. Scientific reasoning in early and middle childhood: the development of domain-general evidence evaluation, experimentation, and hypothesis generation skills.

    2013-06-01

    According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation, and non-covariation evidence emerges, (b) when experimentation emerges, (c) when hypothesis generation skills emerge, and (d), whether these abilities develop synchronously during childhood. We administered three scientific reasoning tasks referring to the three components to 223 children of five age groups (from age 4.0 to 13.5 years). Our results show that the three cognitive components of domain-general scientific reasoning emerge asynchronously. The development of domain-general scientific reasoning begins with the ability to handle unambiguous data, progresses to the interpretation of ambiguous data, and leads to a flexible adaptation of hypotheses according to the sufficiency of evidence. When children understand the relation between the level of ambiguity of evidence and the level of confidence in hypotheses, the ability to differentiate conclusive from inconclusive experiments accompanies this development. Implications of these results for designing science education concepts for young children are briefly discussed. © 2012 The British Psychological Society.

    Full Text Available This work is based on cultural-historical theory from Vygotsky and on the National Curricular Parameters - Curricular Adaptations (1998 - aiming to discuss the importance of learning scientific concepts (the concepts learned through formal/ academic education to the development of students with special educational needs. It is characterized as a theoretical essay based on bibliographical research. The discussion axis is the idea of curricular adaptation/flexibility, since there is no real inclusion without considering the individualized education to meet the specific needs of students. The importance attached to school curriculum and scientific concepts referred to it is based on the Vygotskian premise stating that the learning promotes development; according to Vygotsky, knowledge systematization and awareness enter into the child mind through the learning of scientific concepts. Due to the importance of these concepts, it is needed to be careful to think about the curricular adaptations; under the justification of adapting the teaching and curriculum to the specificities of students with special needs. The formal contents are often disregarded, assuming that they would not be within the capacity scope of students, especially those ones with more pronounced difficulties. It is concluded that learning - learning scientific concepts - promotes cognitive development; then, schooling should invest at this point. It is imperative to fight for an inclusive school in which the children, in fact, can learn, learn contents.

    Tree-ring science provides an engaging, intuitive, and relevant entryway into understanding both climate change and environmental research. It also sheds light on the process of science--from inspiration, to fieldwork, to analysis, to publishing and communication. The basic premise of dendrochronology is that annual rings reflect year-to-year environmental conditions and that by studying long-lived trees we can learn about environmental and climatic conditions going back hundreds to thousands of years. Conceptually, this makes tree-ring studies accessible to students and faculty for a number of reasons. First, in order to collect their data, dendrochronologists often launch expeditions to stunningly picturesque and remote places in search of long-lived, climate sensitive trees. The exciting stories and images that scientists bring back from the field can help connect students to the studies, their motivation, and the data collected. Second, tree rings can be more easily explained as a proxy for climate than ice cores, speleothems and others. Most people have prior knowledge about trees and annual growth rings. It is even possible, for example, for non-expert audiences to see climate variability through time with the naked eye by looking at climate-sensitive tree cores. Third, tree rings are interdisciplinary and illustrate the interplay between the mathematical sciences, the biological sciences, and the geosciences—that is, they show that the biosphere is a fundamental component of the Earth system. Here, we present online, multi-media learning modules for undergraduates that introduce students to several foundational studies in tree-ring science. These include evaluating tree-ring cores from ancient hemlock trees growing on a talus slope in New Paltz, NY to learn about drought in the Northeastern US, evaluating long-term streamflow and drought of the Colorado River based on tree-ring records, and using tree-ring dating techniques to develop construction

    Some facts and figures are present in the existent interaction between the Instituto de Pesquisas Energeticas e Nucleares (IPEN) and the medical community. Among other characteristics, the IPEN has a permanent seat in the Biology and Nuclear Medicine Society and, the present Radiopharmacy Center, has had the continuous concern, since the Instituto de Energia Atomica (IEA) creation until today (2009), to perform an excellent approach with the medical faculty. In the past, some physicians would complete their courses in Europe and in the United States of America, and there noticed the importance of radioisotopes applications in medicine, mainly, in the beginning of these activities, with the I-131. Returning to Brazil, they requested that the former IEA, today IPEN researchers used the research reactor IEA-R1, installed in Sao Paulo, at Universidade Sao Paulo (USP) campus, for radioisotopes production. Then, in the late 1959, the first production line from the I-131 took place. The IPEN starts to accomplish what was planned as one of its targets, at the act of its official creation on August 31, 1956. From 1961 on, there was a continuous flux of I-131 and other radiopharmaceuticals production. The recovery and analysis of these happenings, in the Brazilian society cultural historic context, were partially published in different previous works. Nevertheless, history is dynamic and gains new interpretations, in the present research, from the reading of novel research sources, both primary and secondary, not explores so far - reports, interviews with IPEN researchers and papers published or divulged in meetings, either scientific or bureaucratic. This research is part of project supported by the Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP), with the aim, among others, of contributing for the analysis of the transformations occurred in all of the IPEN research lines, plus the social role of this institution for science and technology development.

    The Galton-Watson branching process has its roots in the problem of extinction of family names which was given a precise formulation by F. Galton as problem 4001 in the Educational Times (17, 1873). In 1875, an attempt to solve this problem was made by H. W. Watson but as it turned out, his conclusion was incorrect. Half a century later, R. A. Fisher made use of the Galton-Watson process to determine the extinction probability of the progeny of a mutant gene. However, it was J. B. S. Haldane who finally gave the first sketch of the correct conclusion. J. B. S. Haldane also predicted that mathematical genetics might some day develop into a "respectable branch of applied mathematics" (quoted in M. Kimura & T. Ohta, Theoretical Aspects of Population Genetics. Princeton, 1971). Since the time of Fisher and Haldane, the two fields of branching processes and mathematical genetics have attained a high degree of sophistication but in different directions. This monograph is a first attempt to apply the current sta...

    Oral supplementation with branched-chain amino acids (BCAA; leucine, isoleucine, and valine) in patients with liver cirrhosis potentially suppresses the incidence of hepatocellular carcinoma (HCC) and improves event-free survival. However, the detailed mechanisms of BCAA action have not been fully elucidated. BCAA were administered to atherogenic and high-fat (Ath+HF) diet-induced nonalcoholic steatohepatitis (NASH) model mice. Liver histology, tumor incidence, and gene expression profiles were evaluated. Ath+HF diet mice developed hepatic tumors at a high frequency at 68 weeks. BCAA supplementation significantly improved hepatic steatosis, inflammation, fibrosis, and tumors in Ath+HF mice at 68 weeks. GeneChip analysis demonstrated the significant resolution of pro-fibrotic gene expression by BCAA supplementation. The anti-fibrotic effect of BCAA was confirmed further using platelet-derived growth factor C transgenic mice, which develop hepatic fibrosis and tumors. In vitro, BCAA restored the transforming growth factor (TGF)-β1-stimulated expression of pro-fibrotic genes in hepatic stellate cells (HSC). In hepatocytes, BCAA restored TGF-β1-induced apoptosis, lipogenesis, and Wnt/β-Catenin signaling, and inhibited the transformation of WB-F344 rat liver epithelial stem-like cells. BCAA repressed the promoter activity of TGFβ1R1 by inhibiting the expression of the transcription factor NFY and histone acetyltransferase p300. Interestingly, the inhibitory effect of BCAA on TGF-β1 signaling was mTORC1 activity-dependent, suggesting the presence of negative feedback regulation from mTORC1 to TGF-β1 signaling. Thus, BCAA induce an anti-fibrotic effect in HSC, prevent apoptosis in hepatocytes, and decrease the incidence of HCC; therefore, BCAA supplementation would be beneficial for patients with advanced liver fibrosis with a high risk of HCC.

  13. Divergence and convergence of commercial and scientific priorities in drug development: The case of Zelmid, the first SSRI antidepressant.

    2015-08-01

    Based on a realist conceptualization of interests, this paper explores how commercial and scientific priorities appear to have converged and diverged during the development of the antidepressant Zelmid. The drug represents the first of the selective serotonin reuptake inhibitors (SSRIs) to reach the market. Zelmid was synthesized in 1971 and launched by the Swedish firm Astra in 1982, but subsequently withdrawn the next year because of adverse neurological effects. This paper draws on in-depth interviews with scientists representing both industry and academia who had high-level involvement in various phases of the project (experimental, pre-clinical and clinical), as well as on textual sources such as scientific articles and memoirs. Zelmid was a product of mechanism-based or "rational" drug discovery from the early 1960s and the associated intermingling of science and commerce. It is argued that both scientists and the pharmaceutical company shared an interest in embracing mechanism-based drug discovery because it simultaneously promised medico-scientific advances and profits. However, the intermingling of science and commerce also strained the relationship between scientific and commercial priorities further along the trajectory of the drug; for example, concerning issues such as dosage strategy and drug use in primary care, where corporate management allegedly took decisions contrary to the recommendations of both academic and company scientists. On such occasions the asymmetry in power became apparent in scientists' narratives: commercial considerations trumped those of science since, ultimately, decisions rest with management, not with scientists. In addition, temporality appears to be associated with the divergence of commercial and scientific priorities. While rare during experimental and pre-clinical phases, divergence was concentrated downstream to the clinical testing and post-marketing phases. It is hypothesized that a similar pattern of convergence and

    Full Text Available In experimental physics, lab notebooks play an essential role in the research process. For all of the ubiquity of lab notebooks, little formal attention has been paid to addressing what is considered “best practice” for scientific documentation and how researchers come to learn these practices in experimental physics. Using interviews with practicing researchers, namely, physics graduate students, we explore the different experiences researchers had in learning how to effectively use a notebook for scientific documentation. We find that very few of those interviewed thought that their undergraduate lab classes successfully taught them the benefit of maintaining a lab notebook. Most described training in lab notebook use as either ineffective or outright missing from their undergraduate lab course experience. Furthermore, a large majority of those interviewed explained that they did not receive any formal training in maintaining a lab notebook during their graduate school experience and received little to no feedback from their advisors on these records. Many of the interviewees describe learning the purpose of, and how to maintain, these kinds of lab records only after having a period of trial and error, having already started doing research in their graduate program. Despite the central role of scientific documentation in the research enterprise, these physics graduate students did not gain skills in documentation through formal instruction, but rather through informal hands-on practice.

    The Fort Collins Science Center's Social and Economic Analysis Branch provides unique capabilities in the U.S. Geological Survey by leading projects that integrate social, behavioral, economic, and natural science in the context of human–natural resource interactions. Our research provides scientific understanding and support for the management and conservation of our natural resources in support of multiple agency missions. We focus on meeting the scientific needs of the Department of the Interior natural resource management bureaus in addition to fostering partnerships with other Federal and State managers to protect, restore, and enhance our environment. The Social and Economic Analysis Branch has an interdisciplinary group of scientists whose primary functions are to conduct both theoretical and applied social science research, provide technical assistance, and offer training to support the development of skills in natural resource management activities. Management and research issues associated with human-resource interactions typically occur in a unique context and require knowledge of both natural and social sciences, along with the skill to integrate multiple science disciplines. In response to these challenging contexts, Social and Economic Analysis Branch researchers apply a wide variety of social science concepts and methods which complement our rangeland/agricultural, wildlife, ecology, and biology capabilities. The goal of the Social and Economic Analysis Branch's research is to enhance natural-resource management, agency functions, policies, and decisionmaking.

  2. Microstrip gas detectors development for the CMS tracker and branching fractions measurement of hadronic B decays with the BaBar experiment

    2007-01-01

    The Compact Muon Solenoid (CMS) is one of the two detectors, designed for the search of the Higgs boson at the Large Hadron Collider (LHC), to operate late 2007 at CERN. Micro Strip Gas Counters (MSGC) have been extensively studied to qualify as part of the CMS tracker. When exposed to highly ionizing particles and to high rates of incident particles, MSGCs have shown a good behavior allowing them to cope with the LHC environment. Similar micro pattern gaseous detectors such as Gas Electron Multiplier (GEM) and Micro Mesh gas detectors (MicroMegas) are developed to be used in high energy physics. BaBar, the detector for the Slac PEP-II asymmetric e + e - B Factory operating at the Y(4S) resonance, was designed to allow comprehensive studies of CP-violation in B-meson decays. First observation of CP violation has been realized in 2001. Since then an impressive amount of B decays measurements has been performed. Among those, we present here the branching fraction measurements of charged and neutral B decays to Dπ - , D * π - , and D ** π - with a missing mass method, based on a sample of 231 million Y(4S) → BB-bar pairs. In order to do this, one of the B mesons is fully reconstructed and the 'recoil' one decays into a reconstructed charged pion and a companion charmed meson identified by its recoil mass, inferred by kinematics. The same sample is used to reconstruct charmed mesons (D, Ds) and baryons (Λ c ) in the 'recoil side' allowing the measurement of the charm number in the B decays. (author)

  3. Sustainable development - a role for nuclear power? 2nd scientific forum

    International Nuclear Information System (INIS)

    2000-03-01

    The 2nd Scientific Forum of the International Atomic Energy Agency (IAEA) was held during the 43rd General Conference. This paper summarizes the deliberations of the two-day Forum. The definition of 'sustainable development' of the 1987 Bruntland Commission - 'development that meets the needs of the present without compromising the ability of future generations to meet their own needs' - provided the background for the Forum's debate whether and how nuclear power could contribute to sustainable energy development. The framework for this debate comprises different perspectives on economic, energy, environmental, and political considerations. Nuclear power, along with all energy generating systems, should be judged on these considerations using a common set of criteria (e.g., emission levels, economics, public safety, wastes, and risks). First and foremost, there is a growing political concern over the possible adverse impact of increasing emissions of greenhouse gases from fossil fuel combustion. However, there is debate as to whether this would have any material impact on the predominantly economic criteria currently used to make investment decisions on energy production. According to the views expressed, the level of safety of existing nuclear power plants is no longer a major concern - a view not yet fully shared by the general public. The need to maintain the highest standards of safety in operation remains, especially under the mounting pressure of competitiveness in deregulated and liberalized energy markets. The industry must continuously reinforce a strong safety culture among reactor designers, builders, and operators. Furthermore, a convincing case for safety will have to be made for any new reactor designs. Of greater concern to the public and politicians are the issues of radioactive waste and proliferation of nuclear weapons. There is a consensus among technical experts that radioactive wastes from nuclear power can be disposed of safely and

    This research aims to develop students’ performance assessment instrument based on scientific approach is valid and reliable in assessing the performance of students on basic physics lab of Simple Harmonic Motion (SHM). This study uses the ADDIE consisting of stages: Analyze, Design, Development, Implementation, and Evaluation. The student performance assessment developed can be used to measure students’ skills in observing, asking, conducting experiments, associating and communicate experimental results that are the ‘5M’ stages in a scientific approach. Each grain of assessment in the instrument is validated by the instrument expert and the evaluation with the result of all points of assessment shall be eligible to be used with a 100% eligibility percentage. The instrument is then tested for the quality of construction, material, and language by panel (lecturer) with the result: 85% or very good instrument construction aspect, material aspect 87.5% or very good, and language aspect 83% or very good. For small group trial obtained instrument reliability level of 0.878 or is in the high category, where r-table is 0.707. For large group trial obtained instrument reliability level of 0.889 or is in the high category, where r-table is 0.320. Instruments declared valid and reliable for 5% significance level. Based on the result of this research, it can be concluded that the student performance appraisal instrument based on the developed scientific approach is declared valid and reliable to be used in assessing student skill in SHM experimental activity.

  5. Branching structure and strain hardening of branched metallocene polyethylenes

    Torres, Enrique; Li, Si-Wan; Costeux, Stéphane; Dealy, John M.

    2015-01-01

    There have been a number of studies of a series of branched metallocene polyethylenes (BMPs) made in a solution, continuous stirred tank reactor (CSTR) polymerization. The materials studied vary in branching level in a systematic way, and the most highly branched members of the series exhibit mild strain hardening. An outstanding question is which types of branched molecules are responsible for strain hardening in extension. This question is explored here by use of polymerization and rheological models along with new data on the extensional flow behavior of the most highly branched members of the set. After reviewing all that is known about the effects of various branching structures in homogeneous polymers and comparing this with the structures predicted to be present in BMPs, it is concluded that in spite of their very low concentration, treelike molecules with branch-on-branch structure provide a large number of deeply buried inner segments that are essential for strain hardening in these polymers

    This report contains information on the activities of the Artificial Intelligence Research Branch (FIA) at NASA Ames Research Center (ARC) in 1992, as well as planned work in 1993. These activities span a range from basic scientific research through engineering development to fielded NASA applications, particularly those applications that are enabled by basic research carried out in FIA. Work is conducted in-house and through collaborative partners in academia and industry. All of our work has research themes with a dual commitment to technical excellence and applicability to NASA short, medium, and long-term problems. FIA acts as the Agency's lead organization for research aspects of artificial intelligence, working closely with a second research laboratory at the Jet Propulsion Laboratory (JPL) and AI applications groups throughout all NASA centers. This report is organized along three major research themes: (1) Planning and Scheduling: deciding on a sequence of actions to achieve a set of complex goals and determining when to execute those actions and how to allocate resources to carry them out; (2) Machine Learning: techniques for forming theories about natural and man-made phenomena; and for improving the problem-solving performance of computational systems over time; and (3) Research on the acquisition, representation, and utilization of knowledge in support of diagnosis design of engineered systems and analysis of actual systems.

  10. ["Directed perception", "mood", "social reinforcement". Sketches towards the historical semantics of Ludwik Fleck's Genesis and Development of a Scientific Fact].

    Science.gov (United States)

    Bauer, Julian

    2014-01-01

    This article analyses three basic concepts of Ludwik Fleck's Genesis and Development of a Scientific Fact. It shows first that Fleck's notion of "directed perception" is closely linked to Jakob von Uexküll's writings on the "Umwelt" of animals and humans. The article then proposes to regard the epistemological debates surrounding parapsychology as an important testing ground for the Fleckian concept of „mood“ and his concomitant hypotheses about „the tenacity of systems of opinion and the harmony of illusions". It finally argues that Fleck's modification of Wilhelm Jerusalem's idea of the "social consolidation" of knowledge helps us to understand the indebtedness of Fleck towards early functionalist sociology as well as his strong belief in "specific historical laws governing the development of ideas"The historical semantics of Fleck's works hence proves that his insights are neither marginal nor revolutionary but rather deeply rooted within scientific traditions from the late 19th and early 20th centuries.

  19. Developing an Arctic Observing Network: Looking Beyond Scientific Research as a Driver to Broader Societal Benefits as Drivers

    Science.gov (United States)

    Jeffries, M. O.

    2017-12-01

    This presentation will address the first ever application of the Societal Benefit Areas approach to continuing efforts to develop an integrated pan-Arctic Observing Network. The scientific research community has been calling for an Arctic Observing Network since the early years of this century, at least. There is no question of the importance of research-driven observations at a time when rapid changes occurring throughout the Arctic environmental system are affecting people and communities in the Arctic and in regions far from the Arctic. Observations are need for continued environmental monitoring and change detection; improving understanding of how the system and its components function, and how they are connected to lower latitude regions; advancing numerical modeling capabilities for forecasting and projection; and developing value-added products and services for people and communities, and for decision- and policymaking. Scientific research is, without question, a benefit to society, but the benefits of Earth observations extend beyond scientific research. Societal Benefit Areas (SBAs) were first described by the international Group on Earth Observations (GEO) and have since been used by USGEO as the basis for its National Earth Observation Assessments. The most recent application of SBAs to Earth observing realized a framework of SBAs, SBA Sub-areas, and Key Objectives required for the completion of a full Earth observing assessment for the Arctic. This framework, described in a report released in June 2017, and a brief history of international efforts to develop an integrated pan-Arctic Observing Network, are the subjects of this presentation.

  20. The Development of a Scientific Motive: How Preschool Science and Home Play Reciprocally Contribute to Science Learning

    Science.gov (United States)

    Gomes, Judith; Fleer, Marilyn

    2017-07-01

    There are a growing number of studies that have examined science learning for preschool children. Some research has looked into children's home experiences and some has focused on transition, practices, routines, and traditions in preschool contexts. However, little attention has been directed to the relationship between children's learning experiences at preschool and at home, and how this relationship can assist in the development of science concepts relevant to everyday life. In drawing upon Hedegaard's (Learning and child development, 2002) cultural-historical conception of motives and Vygotsky's (The collected works of L.S. Vygotsky: problems of general psychology, 1987) theory of everyday and scientific concept formation, the study reported in this paper examines one child, Jimmy (4.2 years), and his learning experiences at home and at preschool. Data gathering featured the video recording of 4 weeks of Jimmy's learning in play at home and at preschool (38.5 h), parent questionnaire and interviews, and researcher and family gathered video observations of home play with his parents (3.5 h). Findings show how a scientific motive develops through playful everyday learning moments at home and at preschool when scientific play narratives and resources are aligned. The study contributes to a more nuanced understanding of the science learning of young children and a conception of pedagogy that takes into account the reciprocity of home and school contexts for learning science.

Results: We analyzed 779 articles published in 85 journals. The majority of articles (n=698; 89.6% were related to the area of Health Sciences. The five journals with higher volumes of articles were: Brazilian Journal of Nutrition, Reports in Public Health, Public Health Journal, Science & Public Health and Journal of Pediatrics. Most (62.4% does not have Journal Citation Reports. The Nutrition area not rated any journal in strata A1 and A2, classifying them from B1 to B4. For eight areas analyzed their specific journals were induced to the upper strata of Qualis (A1, A2 and B1. Conclusion: The analyzed journals are the main vehicles of circulation of scientific paradigms of national scientific communities. Considering the correlation of forces between the vehicles of circulation of scientific knowledge in the international context, stimuli for valorization and qualification of these journals are essential.

    Grapevine berries undergo complex biochemical changes during fruit maturation, many of which are dependent upon the variety and its environment. In order to elucidate the varietal dependent developmental regulation of primary and specialized metabolism, berry skins of Cabernet Sauvignon and Shiraz were subjected to gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) based metabolite profiling from pre-veraison to harvest. The generated dataset was augmented with transcript profiling using RNAseq. The analysis of the metabolite data revealed similar developmental patterns of change in primary metabolites between the two cultivars. Nevertheless, towards maturity the extent of change in the major organic acid and sugars (i.e. sucrose, trehalose, malate) and precursors of aromatic and phenolic compounds such as quinate and shikimate was greater in Shiraz compared to Cabernet Sauvignon. In contrast, distinct directional projections on the PCA plot of the two cultivars samples towards maturation when using the specialized metabolite profiles were apparent, suggesting a cultivar-dependent regulation of the specialized metabolism. Generally, Shiraz displayed greater upregulation of the entire polyphenol pathway and specifically higher accumulation of piceid and coumaroyl anthocyanin forms than Cabernet Sauvignon from veraison onwards. Transcript profiling revealed coordinated increased transcript abundance for genes encoding enzymes of committing steps in the phenylpropanoid pathway. The anthocyanin metabolite profile showed F3'5'H-mediated delphinidin-type anthocyanin enrichment in both varieties towards maturation, consistent with the transcript data, indicating that the F3'5'H-governed branching step dominates the anthocyanin profile at late berry development. Correlation analysis confirmed the tightly coordinated metabolic changes during development, and suggested a source-sink relation between the central and specialized

    At first this will involve the policy makers at the central level, like the Ministry of Education and Sciences and the main research actors in the public and in the private sector. The criteria of the geographical and the subjects coverage has been also used in order to be able to present a public institutions of the higher education and research but even the enterprises that act in the research area are mainly focusing to the integration of these two systems which have been working separately for a long period of time and that must become efficient in order to adapt to the conditions of a country that has limited financial resources. This article is intended to provide a comprehensive overview of the scientific research in Albania, focusing in defining the priority areas for the research in social sciences. The information about the higher education and the potential problems that it faces, is based on a big number of research institutions, selected based on their involvement in scientific research in social sciences. This article brings into evidence the fact that in order to establish a stable and effective infrastructure in scientific research in Albania, is important to work in different directions. A successful way to increase the efficasity through the elements of the “innovative system” is by working with organizations that work in specific sectors of the economy, aiming for a possible cooperation in scientific search, for an important social contribution.

    Scientists are increasingly called upon to communicate with the public, yet most never receive formal training in this area. Public understanding is particularly critical to maintaining support for undervalued resources such as biological collections, research data repositories, and expensive equipment. We describe activities carried out in an inquiry-driven organismal biology laboratory course designed to engage a diverse student body using biological collections. The goals of this cooperative learning experience were to increase students' ability to locate and comprehend primary research articles, and to communicate the importance of an undervalued scientific resource to nonscientists. Our results indicate that collaboratively created, research-focused informational posters are an effective tool for achieving these goals and may be applied in other disciplines or classroom settings.

    Improving laboratory animal science and welfare requires both new scientific research and insights from research in the humanities and social sciences. Whilst scientific research provides evidence to replace, reduce and refine procedures involving laboratory animals (the '3Rs'), work in the humanities and social sciences can help understand the social, economic and cultural processes that enhance or impede humane ways of knowing and working with laboratory animals. However, communication across these disciplinary perspectives is currently limited, and they design research programmes, generate results, engage users, and seek to influence policy in different ways. To facilitate dialogue and future research at this interface, we convened an interdisciplinary group of 45 life scientists, social scientists, humanities scholars, non-governmental organisations and policy-makers to generate a collaborative research agenda. This drew on methods employed by other agenda-setting exercises in science policy, using a collaborative and deliberative approach for the identification of research priorities. Participants were recruited from across the community, invited to submit research questions and vote on their priorities. They then met at an interactive workshop in the UK, discussed all 136 questions submitted, and collectively defined the 30 most important issues for the group. The output is a collaborative future agenda for research in the humanities and social sciences on laboratory animal science and welfare. The questions indicate a demand for new research in the humanities and social sciences to inform emerging discussions and priorities on the governance and practice of laboratory animal research, including on issues around: international harmonisation, openness and public engagement, 'cultures of care', harm-benefit analysis and the future of the 3Rs.

    Kitsikopoulos, Harry

    2013-09-01

    This essay provides an analytical account of the history of various steam devices by tracing the key technological and scientific developments culminating in the Savery and Newcomen models. It begins in antiquity with the writings of Hero of Alexandria, which were rediscovered and translated in Italy fourteen centuries later, followed by the construction of simple steam devices. The most decisive development comes in the middle of the seventeenth century with the overturning, through the experimental work of Torricelli, Pascal, and Guericke, of the Aristotelian dogma that no vacuum exists. The final stretch of this discovery process amounted to an Anglo-French race, with English inventors being more successful in the end.

    Dunbar, Terry Frank

    The use of the scientific inquiry method of teaching science was investigated in one district's elementary schools. The study generated data directly from Albuquerque Public Schools fourth- and fifth-grade teachers through a mail-out survey and through observation. Two forms of an inquiry evaluation research instrument (Elementary Science Inquiry Survey - ESIS) were created. The ESIS-A is a classroom observation tool. The ESIS-B is a survey questionnaire designed to collect information from teachers. The study was designed first to establish reliability and validity for both forms of the instrument. The study made use of multiple regression and exploratory factor analysis. Sources used to establish the instruments' reliability and validity included: (1) Input from an international panel (qualitative analysis of comments sent by raters and quantitative analysis of numerical ratings sent by raters); (2) Cronbach's alpha; (3) Results of factor analysis; (4) Survey respondents' comments (qualitative analysis); (5) Teacher observation data. Cronbach's alpha for the data set was .8955. Inquiry practices were reported to occur between twice per week and three times per week. Teachers' comments regarding inquiry were reported. The ESIS was used to collect inquiry self-report data and teacher background data. The teacher background data included teacher science knowledge and information about their standards awareness and implementation. The following teacher knowledge factors were positively correlated with inquiry use: semesters of college science, science workshops taken, conducted scientific research, and SIMSE (NSF institute) participation. The following standards awareness and implementation factors were positively correlated with inquiry use: familiarity with the National Science Education Standards, familiarity with New Mexico science standards, state or national standards as a curriculum selection factor, student interest as a curriculum selection factor, and "no

    The current text reviewed the situation of the scientific research in the field of Optometry and visual sciences in the recent 5 to 6 years in our country. It showed the advancement and achievement in the myopic fundamental research and the application research of visual science. In addition, it also analyzed the guidance of research in solving the clinical visual issues and the significance of community service of research in eye care in public. This text indicated by the concrete current situation and the result data of research that the biology and optics, the double property of the eye endowed the distinguished feature to the research in Ophthalmology and Optometry, and that the cross cooperation of multidisciplinary promoted the innovation in the fields of Optometry and visual research. In future, the fields of Optometry and visual science in China will face up to more and more anticipations of the original and systematic research. The prophylaxis and treatment of myopia would be still a long-term and rough exploration theme in these fields.

  1. Human and animal research guidelines: aligning ethical constructs with new scientific developments.

    Science.gov (United States)

    Ferdowsian, Hope

    2011-10-01

    Both human research and animal research operate within established standards and procedures. Although the human research environment has been criticized for its sometimes inefficient and imperfect process, reported abuses of human subjects in research served as the impetus for the establishment of the Nuremberg Code, Declaration of Helsinki, and the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research and the resulting Belmont Report. No similar, comprehensive and principled effort has addressed the use of animals in research. Although published policies regarding animal research provide relevant regulatory guidance, these policies have not emerged from the process of specifying consistent and reasoned ethical principles. The lack of a fundamental effort to explore the ethical issues and principles regarding the use of animals in research has led to unclear and disparate policies. Recent studies have increased our understanding of animal cognition and emotion, suggesting that animals' potential for experiencing a wide variety of harms, such as pain and fear, is greater than has been previously appreciated. Furthermore, relationships between methods of captivity and certain laboratory procedures and the resulting adverse physical, social and psychological effects have been established. In light of this information, current protections may need to be reconsidered and modified. This paper explores the historical convergence and divergence in the creation of human and animal research guidelines, as well as opportunities to align ethical frameworks with new scientific discoveries. © 2011 Blackwell Publishing Ltd.

    2015-09-01

    The 2010 report of the United Kingdom Science and Technology Committee of the House of Commons and the 2015 report of the Australian National Health and Medical Research Council have overtaken in significance the uncritical Swiss report of 2012 and have gone a long way to changing the environment of tolerance toward proselytising claims of efficacy in respect of homeopathy. The inquiry being undertaken in the United States by the Food and Drug Administration during 2015 may accelerate this trend. An outcome of the reports and inquiries has been a series of decisions from advertising regulators and by courts rejecting medically unjustifiable claims in respect of the efficacy of homeopathy. Class actions have also been initiated in North America against manufacturers of homeopathic products. The changing legal and regulatory environment is generating an increasingly scientifically marginalised existence for homeopathy. That new environment is starting to provide effective inhibition of assertions on behalf of homeopathy and other health modalities whose claims to therapeutic efficacy cannot be justified by reference to the principles of evidence-based health care. This has the potential to reduce the financial support that is provided by insurers and governments toward homeopathy and to result in serious liability exposure for practitioners, manufacturers and those who purvey homeopathic products, potentially including pharmacists. In addition, it may give a fillip to a form of regulation of homeopaths if law reform to regulate unregistered health practitioners gathers momentum, as is taking place in Australia.

    Species sensitivity distributions (SSDs) are used in ecological risk assessment for extrapolation of the results of toxicity tests with single species to a toxicity threshold considered protective of ecosystem structure and functioning. The attention to and importance of the SSD approach has increased in scientific and regulatory communities since the 1990s. Discussion and criticism have been triggered on the concept of the approach as well as its technical aspects (e.g., distribution type, number of toxicity endpoints). Various questions remain unanswered, especially with regard to different endpoints, statistical methods, and protectiveness of threshold levels, for example. In the present literature review (covering the period 2002-2013), case studies are explored in which the SSD approach was applied, as well as how endpoint types, species choice, and data availability affect SSDs. How statistical methods may be used to construct reliable SSDs and whether the lower 5th percentile hazard concentrations (HC5s) from a generic SSD can be protective for a specific local community are also investigated. It is shown that estimated protective concentrations were determined by taxonomic groups rather than the statistical method used to construct the distribution. Based on comparisons between semifield and laboratory-based SSDs, the output from a laboratory SSD was protective of semifield communities in the majority of studies.

    2010-11-01

    Full Text Available Abstract Background Lungs develop from the fetal digestive tract where epithelium invades the vascular rich stroma in a process called branching morphogenesis. In organogenesis, endothelial cells have been shown to be important for morphogenesis and the maintenance of organ structure. The aim of this study was to recapitulate human lung morphogenesis in vitro by establishing a three dimensional (3D co-culture model where lung epithelial cells were cultured in endothelial-rich stroma. Methods We used a human bronchial epithelial cell line (VA10 recently developed in our laboratory. This cell line cell line maintains a predominant basal cell phenotype, expressing p63 and other basal markers such as cytokeratin-5 and -14. Here, we cultured VA10 with human umbilical vein endothelial cells (HUVECs, to mimic the close interaction between these cell types during lung development. Morphogenesis and differentiation was monitored by phase contrast microscopy, immunostainings and confocal imaging. Results We found that in co-culture with endothelial cells, the VA10 cells generated bronchioalveolar like structures, suggesting that lung epithelial branching is facilitated by the presence of endothelial cells. The VA10 derived epithelial structures display various complex patterns of branching and show partial alveolar type-II differentiation with pro-Surfactant-C expression. The epithelial origin of the branching VA10 colonies was confirmed by immunostaining. These bronchioalveolar-like structures were polarized with respect to integrin expression at the cell-matrix interface. The endothelial-induced branching was mediated by soluble factors. Furthermore, fibroblast growth factor receptor-2 (FGFR-2 and sprouty-2 were expressed at the growing tips of the branching structures and the branching was inhibited by the FGFR-small molecule inhibitor SU5402. Discussion In this study we show that a human lung epithelial cell line can be induced by endothelial cells to

    Morphometric analyses of biological features have become increasingly common in recent years with such analyses being subject to a large degree of observer bias, variability, and time consumption. While commercial software packages exist to perform these analyses, they are expensive, require extensive user training, and are usually dependent on the observer tracing the morphology. To address these issues, we have developed a broadly applicable, no-cost ImageJ plugin we call 'BranchAnalysis2D/3D', to perform morphometric analyses of structures with branching morphologies, such as neuronal dendritic spines, vascular morphology, and primary cilia. Our BranchAnalysis2D/3D algorithm allows for rapid quantification of the length and thickness of branching morphologies, independent of user tracing, in both 2D and 3D data sets. We validated the performance of BranchAnalysis2D/3D against pre-existing software packages using trained human observers and images from brain and retina. We found that the BranchAnalysis2D/3D algorithm outputs results similar to available software (i.e., Metamorph, AngioTool, Neurolucida), while allowing faster analysis times and unbiased quantification. BranchAnalysis2D/3D allows inexperienced observers to output results like a trained observer but more efficiently, thereby increasing the consistency, speed, and reliability of morphometric analyses.

  1. Scientific instruments, scientific progress and the cyclotron

    International Nuclear Information System (INIS)

    Baird, David; Faust, Thomas

    1990-01-01

    Philosophers speak of science in terms of theory and experiment, yet when they speak of the progress of scientific knowledge they speak in terms of theory alone. In this article it is claimed that scientific knowledge consists of, among other things, scientific instruments and instrumental techniques and not simply of some kind of justified beliefs. It is argued that one aspect of scientific progress can be characterized relatively straightforwardly - the accumulation of new scientific instruments. The development of the cyclotron is taken to illustrate this point. Eight different activities which promoted the successful completion of the cyclotron are recognised. The importance is in the machine rather than the experiments which could be run on it and the focus is on how the cyclotron came into being, not how it was subsequently used. The completed instrument is seen as a useful unit of scientific progress in its own right. (UK)

    Ngotho, E.M.

    2010-01-01

    The need for involvement of Technical and Scientific Support Organisations (TSO) in developing countries intending to launch a nuclear power programme (NPP) cannot be overemphasized. In an International Conference on Topical Issues in Nuclear Installation Safety held in 2008, Mumbai, India, I presented a paper entitled 'Launching a Nuclear Power Programme - a third world country's perspective' - IAEA-CN-158/9. I pointed out some real constraints encountered by a developing country while trying to introduce a nuclear power programme. This was inadequate base infrastructure, financial incapability and lack of skilled manpower. Granted there are areas where the role of TSOs is minimal like in carrying the actual cost of infrastructure but their input in areas of technology, evaluation, assessment and skills development cannot be gainsaid.

  4. A Component Approach to Collaborative Scientific Software Development: Tools and Techniques Utilized by the Quantum Chemistry Science Application Partnership

    Directory of Open Access Journals (Sweden)

    Joseph P. Kenny

    2008-01-01

    Full Text Available Cutting-edge scientific computing software is complex, increasingly involving the coupling of multiple packages to combine advanced algorithms or simulations at multiple physical scales. Component-based software engineering (CBSE has been advanced as a technique for managing this complexity, and complex component applications have been created in the quantum chemistry domain, as well as several other simulation areas, using the component model advocated by the Common Component Architecture (CCA Forum. While programming models do indeed enable sound software engineering practices, the selection of programming model is just one building block in a comprehensive approach to large-scale collaborative development which must also address interface and data standardization, and language and package interoperability. We provide an overview of the development approach utilized within the Quantum Chemistry Science Application Partnership, identifying design challenges, describing the techniques which we have adopted to address these challenges and highlighting the advantages which the CCA approach offers for collaborative development.

    1999-01-01

    In recognition of the 1997 anniversary of the first century of radiochemistry, a review is made of its unique contribution to the emergence of nuclear science, its development from the use of very basic chemical techniques initially to a battery of more sophisticated procedures, and its changing role as it has become widely applied in many fields of science. Synergistically, these fields have been able to develop with the aid of radiochemistry while at the same time, radiochemical methods developed to meet the demands of such applications, Among these, during the second half of the century, has been radiochemistry applied to quantitative chemical analysis: RAA or, nuclear analytical chemistry, and typical examples of its use in the authors' laboratory are described, including some recent INAA results on development of novel 'activable' tracer coding for forensic use with specialized and high security materials. The specific contributions, during the century, of Japanese pioneers in radiochemistry are also cited. (author)

    1998-01-01

    It is observed that new and sophisticated technologies developed through research and development in relation to magnetic confinement fusion have been transferred to other industrial and scientific fields with remarkable spin-off effects. Approximately 10 years ago, the Japan Atomic Industrial Forum (JAIF) has investigated technical transfer and spin-off effects of fusion technologies developed in Japan. The essence of the results of this investigation as well as high technologies developed in the last decade, some of which are in the early stage of technical spin-off, are described. It is additionally explained that independent technical development conducted by our country as well as by engineers themselves is important in achieving effective spin-off. An outline of scientific spin-off effects is also described, including utilization technologies of fusion reactions besides those for energy production purposes, the progress of scientific understanding in the course of fusion research, and scientific information transfer and communication with other fields.

    Tavss, Edward A; Fisher, Steven W; Campbell, Shannon; Bonta, Yolanda; Darcy-Siegel, Joann; Blackwell, Bernie L; Volpe, Anthony R; Miller, Steven E

    2004-02-01

    To describe the development of a new dentin hypersensitivity treatment, Colgate Sensitive Maximum Strength dentifrice, containing 5% potassium nitrate as the anti-hypersensitivity active agent. The objective was to develop a home-use hypersensitivity dentifrice that would be superior to the market leader, improving on what is available, which also contains 5% potassium nitrate as the anti-hypersensitivity active agent. In vivo (clinicals, taste evaluation and rat caries), in vitro (potassium flux) and analytical (rheology, dispensed volume, scanning electron microscopy, electron scanning chemical analysis and radioactive dentin abrasion) methods were performed. The objective was accomplished with the development of a new activated silica technology that resulted in enhanced potassium ion activity. In vitro documentation, supported by clinical studies, demonstrated that the resulting formula is more effective than the market leader for relief of hypersensitivity pain. Fast pain relief in less than 2 weeks and long-lasting protection against pain with regular use have also been clinically documented. Furthermore, FDA-required in vivo and in vitro studies indicate that this formula, which contains 0.45% stannous fluoride (1100 ppm fluoride) as the anti-caries active agent, is effective against caries. Good taste, acceptable rheology, acceptable abrasivity, and cosmetic and chemical stability have all been engineered into this unique dentin hypersensitivity treatment. In summary, a highly efficacious consumer friendly treatment for dentin hypersensitivity has been developed.

  16. Developing automated analytical methods for scientific environments using LabVIEW.

    Wagner, Christoph; Armenta, Sergio; Lendl, Bernhard

    2010-01-15

    The development of new analytical techniques often requires the building of specially designed devices, each requiring its own dedicated control software. Especially in the research and development phase, LabVIEW has proven to be one highly useful tool for developing this software. Yet, it is still common practice to develop individual solutions for different instruments. In contrast to this, we present here a single LabVIEW-based program that can be directly applied to various analytical tasks without having to change the program code. Driven by a set of simple script commands, it can control a whole range of instruments, from valves and pumps to full-scale spectrometers. Fluid sample (pre-)treatment and separation procedures can thus be flexibly coupled to a wide range of analytical detection methods. Here, the capabilities of the program have been demonstrated by using it for the control of both a sequential injection analysis - capillary electrophoresis (SIA-CE) system with UV detection, and an analytical setup for studying the inhibition of enzymatic reactions using a SIA system with FTIR detection.

    Durrett, Richard

    2015-01-01

    This volume develops results on continuous time branching processes and applies them to study rate of tumor growth, extending classic work on the Luria-Delbruck distribution. As a consequence, the authors calculate the probability that mutations that confer resistance to treatment are present at detection and quantify the extent of tumor heterogeneity. As applications, the authors evaluate ovarian cancer screening strategies and give rigorous proofs for results of Heano and Michor concerning tumor metastasis. These notes should be accessible to students who are familiar with Poisson processes and continuous time. Richard Durrett is mathematics professor at Duke University, USA. He is the author of 8 books, over 200 journal articles, and has supervised more than 40 Ph.D. students. Most of his current research concerns the applications of probability to biology: ecology, genetics, and most recently cancer.

  20. Thermoelectric effects in disordered branched nanowires

    Science.gov (United States)

    Roslyak, Oleksiy; Piriatinskiy, Andrei

    2013-03-01

    We shall develop formalism of thermal and electrical transport in Si1 - x Gex and BiTe nanowires. The key feature of those nanowires is the possibility of dendrimer type branching. The branching tree can be of size comparable to the short wavelength of phonons and by far smaller than the long wavelength of conducting electrons. Hence it is expected that the branching may suppress thermal and let alone electrical conductance. We demonstrate that the morphology of branches strongly affects the electronic conductance. The effect is important to the class of materials known as thermoelectrics. The small size of the branching region makes large temperature and electrical gradients. On the other hand the smallness of the region would allow the electrical transport being ballistic. As usual for the mesoscopic systems we have to solve macroscopic (temperature) and microscopic ((electric potential, current)) equations self-consistently. Electronic conductance is studied via NEGF formalism on the irreducible electron transfer graph. We also investigate the figure of merit ZT as a measure of the suppressed electron conductance.

    Ziegele, B; Dahl, L; Müller, A T

    2011-07-01

    In conformity with Regulation (EC) No. 1394/2007, advanced therapy medicinal products (ATMP) are now subject to the centralized marketing authorization procedure. This also applies to most medicinal products in regenerative medicine. ATMP that have been marketed in a member state by the end of 2008 must be centrally authorized by the end of 2012 at the latest. In exceptional cases, a national authorization is acceptable. Developers of these medicinal products are usually academic institutions or small- and medium-sized enterprises (SME). They focus on scientific aspects and usually have little experience with pharmaceutical law. The Innovation Office of the Paul-Ehrlich-Institut (PEI) is designed to support developers of medicinal products in the areas between research and development, on the one hand, and regulatory requirements, on the other. Its main role is supportive advice in the regulatory field with an emphasis on ATMP. For this purpose, the Innovation Office makes use of core competences from various experts at the PEI in order to provide a quality consulting service to those companies who are seeking advice as early as possible and hand in hand with the development process. The aim is to support the developer to identify the appropriate regulatory pathway and to provide advice for each individual medicinal product at its corresponding stage of development in order to develop a high-quality ATMP manufactured on the basis of positive nonclinical results and appropriate clinical studies that meet all the necessary requirements for the application of a marketing authorization.

  6. SCIENTIFIC POLICY OF SAUDI ARABIA: INTERNATIONAL SCIENCE AS A BASIS FOR DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    T. I. Tyukaeva

    2016-01-01

    Full Text Available In less than a century of its existence Saudi Arabia has developed from mass illiteracy and lack of education of its population into the current state of complex structure of educational and research institutions and organizations equipped with most modern and advanced technologies and top world specialists in accordance with the highest international standards. It is especially important that the Kingdom has managed to achieve such success in no time. Until lately scientifi c development in Saudi Arabia was mostly concentrated on applied research, especially in the Kingdom’s key economic sphere – energy. Despite the country’s abundant financial resources, science was considerably underfunded and lacked any development strategy. Meanwhile, in the last 15 years the Saudi Kingdom has made a huge leap in scientifi c development with a clear action plan worked out, a solid structure of scientifi c institutes formed and the world experience effi ciently used. The success came with the Saudi authorities’ realization of the importance of scientifi c and technical progress both for the national economy and political positions of the state in the region and in the world. The article aims to analyze the scientifi c policy of Saudi Arabia on the stage of its birth and in the current state by means of studying offi cial documents, statistics and the existing institutes in the scientifi c system of the Kingdom. The author concludes that the key features of the Saudi scientifi c policy are prevailing role of the state, priority of applied over fundamental research and internalization with serious dependency on foreign support in the absence of a national scientifi c tradition.

  7. Scientific Growth and Identity Development during a Postbaccalaureate Program: Results from a Multisite Qualitative Study.

    2016-01-01

    This report builds upon our previous study, which described five patterns of why college graduates join National Institutes of Health (NIH)-funded diversity-focused Postbaccalaureate Research Education Programs (PREP). A 2015 report from the NIH showed that a high fraction of PREP participants matriculate into PhD and MD/PhD programs. This current study reveals how participants change during PREP, the program elements that facilitate change, and how identity as a graduate student and future scientist develops. Data come from in-depth interviews done at the beginning and end of PREP with 48 individuals from seven PREP programs. Results reveal three domains of development: academics, research, and presentation of oneself; each domain contains a developmental continuum. Key attributes of PREP enabling development include opportunities to attend graduate-level classes and seminars; time to practice reading literature; extended lab time with one's own project; high and explicit expectations from mentors; and multiple opportunities to talk about science and improve communication skills. PREP enabled participants to develop their identities as graduate students and to anticipate being seen by others as highly prepared for PhD training. After PREP, 85% (n = 41) started the PhD or MD/PhD, making PREP an intervention approach with great potential to broaden participation in biomedical PhD programs. © 2016 R. Remich et al.

  8. Cell-free oxygen carriers: scientific foundations, clinical development, and new directions.

    Science.gov (United States)

    Winslow, Robert M

    2008-10-01

    The most significant hurdle to the development of a safe and effective hemoglobin-based oxygen carrier ("blood substitute") is generally thought to be its propensity to cause vasoconstriction in the microcirculation and hypertension. Two theories for this effect are currently being studied: in one, scavenging NO by hemoglobin reduces vasorelaxation; in the other, cell-free hemoglobin oversupplies O2 (a known vasoconstrictor) to vascular walls by facilitated diffusion. While both mechanisms might lead to reduction of local NO concentration, the important distinction between the two is that if the NO scavenging theory is correct, it greatly diminishes the prospects to develop any solution based on free hemoglobin. However, if the O2-oversupply theory is correct, modifications to the hemoglobin molecule can be envisioned that can prevent oversupply and reduce toxicity. This review summarizes the development of Hemospan, a novel modification of human hemoglobin whose design is based on the O2-oversupply theory. Because of its low P50 and increased molecular size, the release of O2 in resistance vessels (arterioles) by Hemospan is restricted, and vasoconstriction is greatly reduced.

    The Millennium Development Goals (MDGs) are now at the midterm of their target period, as 2015 is the date scheduled by the United Nations Organisation (UN) for their attainment. The purpose of this article is to review the current situation of the MDGs worldwide and to analyse the barriers which are preventing them from being attained in each of the MDG areas, as well as to assess a number of the indicators evaluated. In order to do so, a review has been made of the scientific literature published on the MDGs in the principal health sciences and social sciences databases, as well as the most significant reports on the issue drawn up by the United Nations. The scientific studies on the 8 MDGs and their 18 Targets make it possible to undertake a critical analysis of the situation in which each of these Goals are found at the present time, identifying the determinants that are preventing the attainment of the Goals and the actions considered necessary in order to achieve progress. Although there have been improvements in some of the goals on a world level, the research carried out to date reveals barriers to the attainment of the MDGs, as well as the insufficient weight of the developing countries in the economic and political decision-making processes, together with the incoherence between the economic policies and the social and health policies. Furthermore, Sub-Saharan Africa constitutes the most disadvantaged region, which means that it will not attain the majority of the MDGs. Spain and the developed countries, in addition to contributing resources, can also contribute to the MDGs by means of the identification and eradication of the barriers preventing attainment. This involves promoting international economic relations under conditions of social justice, by supporting a greater decision-making power for developing countries and denouncing actions that increase social inequalities and the impoverishment of the population.

    This paper deals with the historical and philosophical background of the introduction of the notion of branching time in philosophical logic as it is revealed in the hitherto unpublished mail-correspondence between Saul Kripke and A.N. Prior in the late 1950s. The paper reveals that the idea...... relativity. The correspondence underpins the point that Prior’s later development of branching time may be understood as a crucial part of his attempt at the formulating a conceptual framework integrating basic human notions of time and free choice....

    2017-07-01

    The bronchial network of the mammalian lung consists of millions of dichotomous branches arranged in a highly complex, space-filling tree. Recent computational models of branching morphogenesis in the lung have helped uncover the biological mechanisms that construct this ramified architecture. In this review, we focus on three different theoretical approaches - geometric modeling, reaction-diffusion modeling, and continuum mechanical modeling - and discuss how, taken together, these models have identified the geometric principles necessary to build an efficient bronchial network, as well as the patterning mechanisms that specify airway geometry in the developing embryo. We emphasize models that are integrated with biological experiments and suggest how recent progress in computational modeling has advanced our understanding of airway branching morphogenesis.

  12. An Overview of the Future Development of Climate and Earth System Models for Scientific and Policy Use (Invited)

    Washington, W. M.

    2010-12-01

    The development of climate and earth system models has been regarded primarily as the making of scientific tools to study the complex nature of the Earth’s climate. These models have a long history starting with very simple physical models based on fundamental physics in the 1960s and over time they have become much more complex with atmospheric, ocean, sea ice, land/vegetation, biogeochemical, glacial and ecological components. The policy use aspects of these models did not start in the 1960s and 1970s as decision making tools but were used to answer fundamental scientific questions such as what happens when the atmospheric carbon dioxide concentration increases or is doubled. They gave insights into the various interactions and were extensively compared with observations. It was realized that models of the earlier time periods could only give first order answers to many of the fundamental policy questions. As societal concerns about climate change rose, the policy questions of anthropogenic climate change became better defined; they were mostly concerned with the climate impacts of increasing greenhouse gases, aerosols, and land cover change. In the late 1980s, the United Nations set up the Intergovernmental Panel on Climate Change to perform assessments of the published literature. Thus, the development of climate and Earth system models became intimately linked to the need to not only improve our scientific understanding but also answering fundamental policy questions. In order to meet this challenge, the models became more complex and realistic so that they could address these policy oriented science questions such as rising sea level. The presentation will discuss the past and future development of global climate and earth system models for science and policy purposes. Also to be discussed is their interactions with economic integrated assessment models, regional and specialized models such as river transport or ecological components. As an example of one

  13. A study of the development of scientific literacy in students of conservative Christian schools

    Science.gov (United States)

    Johns, Christopher D.

    A collision of concepts often occurs within the science classrooms of Christian schools. Students are faced with the task of accommodating biblical teachings with science theories that are not only incompatible but often directly conflicting. Teachers in the Christian school must choose to what extent and how this conflicting information will be addressed. Students must manage the tension caused by this conflict and then determine their own belief systems. High-stakes achievement testing also plays a role in the curriculum and instruction of science in the Christian school as well as public schools. Science literacy, a lifelong pursuit of understanding of the physical world, can be a victim of instructional strategies aimed at promoting student success on a specific test covering a specific set of facts instead of a comprehensive plan developed for individual-specific growth. This study was designed to gain an understanding of science literacy development of the middle school student in the Christian school. This was accomplished by comparing the individual component scores of the science Indiana Statewide Testing for Educational Progress-Plus achievement test for a 3-year period of 5 Christian schools in Indiana to the overall state averages. Armed with this information, the study, in its second phase, included interviews of the 7th-grade science teachers of the included schools. The goal of the interviews was to provide meaning and substance to the score comparisons. The purpose of the study was to understand how the students in Christian schools compared to the overall population of students in areas of science that may conflict with their Biblical beliefs. Additionally, this study was developed to understand how the science teachers in Christian schools managed the conflict that develops between the Bible and theories of science. Findings from this study showed that students in Christian schools continue to score higher than the overall population of students

    Joshua L Rosenbloom

    Full Text Available This article examines the relationship between Research & Development (R&D funding and the production of knowledge by academic chemists. Using articles published, either raw counts or adjusted for quality, we find a strong, positive causal effect of funding on knowledge production. This effect is similar across subsets of universities, suggesting a relatively efficient allocation of R&D funds. Finally, we document a rapid acceleration in the rate at which chemical knowledge was produced in the late 1990s and early 2000s relative to the financial and human resources devoted to its production.

  17. Development of high performance scientific components for interoperability of computing packages

    Energy Technology Data Exchange (ETDEWEB)

    Gulabani, Teena Pratap [Iowa State Univ., Ames, IA (United States)

    2008-01-01

    Three major high performance quantum chemistry computational packages, NWChem, GAMESS and MPQC have been developed by different research efforts following different design patterns. The goal is to achieve interoperability among these packages by overcoming the challenges caused by the different communication patterns and software design of each of these packages. A chemistry algorithm is hard to develop as well as being a time consuming process; integration of large quantum chemistry packages will allow resource sharing and thus avoid reinvention of the wheel. Creating connections between these incompatible packages is the major motivation of the proposed work. This interoperability is achieved by bringing the benefits of Component Based Software Engineering through a plug-and-play component framework called Common Component Architecture (CCA). In this thesis, I present a strategy and process used for interfacing two widely used and important computational chemistry methodologies: Quantum Mechanics and Molecular Mechanics. To show the feasibility of the proposed approach the Tuning and Analysis Utility (TAU) has been coupled with NWChem code and its CCA components. Results show that the overhead is negligible when compared to the ease and potential of organizing and coping with large-scale software applications.

    Proton radiography offers significant advantages over conventional X-ray radiography, including the capability of looking into thick, dense materials, better contrast for a wide range of materials, sensitivity to different materials of similar density, and better resolution because of the ability to focus beams. In order to achieve this capability it is crucial to understand the background due to neutrons and photons and to develop techniques to reduce it to tolerable levels. The physics goal of this project is to measure forward production of neutrons and photons produced by high-energy proton beams striking a variety of targets. This work is being carried out in conjunction with the Fermilab Experiment 907 (MIPP) collaboration including physicists from Lawrence Livermore Laboratory. Our group is responsible for the E907 forward neutron/photon calorimeters. These are the only detectors in the experiment that provide information on neutrons and photons. We are taking a leading role in obtaining and analyzing the for-ward production data and in developing an optimal detector for proton radiography. With the support of our Stewardship Science Academic Alliances grant, we were able to design, build, and commission the calorimeters on budget and ahead of schedule. E-907 officially started physics running at Fermilab in January 2005, and data taking continued through February 2006. Data were taken on a range of targets, from liquid hydrogen to uranium, at beam energies from 5 GeV/c to 120 GeV/c. The analysis of the data is challenging because data from many different detector systems must be understood and merged and over 31 million events were accumulated. Our recent efforts have been devoted to the calibration of the neutron and photon detectors, to track and shower reconstruction, identification of forward-going neutrons, and simulation of the calorimeters in a Monte Carlo. Reconstruction of the data with improved tracking is underway

    Full Text Available The paper outlines science and methodological aspects of issuing bulletins for the civil aircraft and practical prob- lems accumulated in the national aviation industry within the mentioned area. Bulletins are used to inform operators about the purpose, data content and technologies outlining the design changes accomplishment if the aircraft considered at the moment of the design changes is already at the operational stage. Hence maintaining aircraft airworthiness is impossible without making certain modifications and repairs in the design, the bulletins issuing and implementation procedures have notable impact on safety and effectiveness of air transportation.Deficiencies considered are the results of practices used since 1980 and supported by the later interstate standard GOST 31270-2004 in the field of the bulletins development and implementation, which are not in line with contemporary conditions of international civil aviation activities. Negative consequences of transferring the Soviet way of working with aircraft bulletins intothe changed conditions of the state regulation of civil aviation activities in Russia are shown as well as those for substantial com-plication of the rules and procedures in comparison to the standards of Unified System of Design Documentation.Main theses of the ICAO standards and international practice are briefly analyzed, however they are not complete- ly presented in the national aviation regulations. The recommendations proposed are aimed to eliminate mentioned defi- ciencies through the standards amendment process and improvement of Russia's civil aviation regulatory base. Developed recommendations are mainly focused on the formulation of the new concept and certain content of the revised standard requirements to replace GOST 31270-2004.

    Increasing students' earth science literacy, especially those at Minority Serving Institutions (MSIs), is a primary goal of the American Meteorological Society (AMS). Through the NSF-supported AMS Weather Studies and AMS Ocean Studies Diversity workshops for Historically Black College and Universities, Hispanic Serving Institutions, Tribal Colleges and Universities, Alaska Native, and Native Hawaiian Serving Institutions, AMS has brought meteorology and oceanography courses to more students. These workshops trained and mentored faculty implementing AMS Weather Studies and AMS Ocean Studies. Of the 145 institutions that have participated in the AMS Weather Studies Diversity Project, reaching over 13,000 students, it was the first meteorology course offered for more than two-thirds of the institutions. As a result of the AMS Ocean Studies Diversity Project, 75 institutions have offered the course to more than 3000 students. About 50 MSIs implemented both the Weather and Ocean courses, improving the Earth Science curriculum on their campuses. With the support of NSF and NASA, and a partnership with Second Nature, the organizing entity behind the American College and University President's Climate Commitment (ACUPCC), the newest professional development workshop, AMS Climate Studies Diversity Project will recruit MSI faculty members through the vast network of Second Nature's more than 670 signatories. These workshops will begin in early summer 2012. An innovative approach to studying climate science, AMS Climate Studies explores the fundamental science of Earth's climate system and addresses the societal impacts relevant to today's students and teachers. The course utilizes resources from respected organizations, such as the IPCC, the US Global Change Research Program, NASA, and NOAA. In addition, faculty and students learn about basic climate modeling through the AMS Conceptual Energy Model. Following the flow of energy in a clear, simplified model from space to

  5. Probabilities and Predictions: Modeling the Development of Scientific Problem-Solving Skills

    Science.gov (United States)

    2005-01-01

    The IMMEX (Interactive Multi-Media Exercises) Web-based problem set platform enables the online delivery of complex, multimedia simulations, the rapid collection of student performance data, and has already been used in several genetic simulations. The next step is the use of these data to understand and improve student learning in a formative manner. This article describes the development of probabilistic models of undergraduate student problem solving in molecular genetics that detailed the spectrum of strategies students used when problem solving, and how the strategic approaches evolved with experience. The actions of 776 university sophomore biology majors from three molecular biology lecture courses were recorded and analyzed. Each of six simulations were first grouped by artificial neural network clustering to provide individual performance measures, and then sequences of these performances were probabilistically modeled by hidden Markov modeling to provide measures of progress. The models showed that students with different initial problem-solving abilities choose different strategies. Initial and final strategies varied across different sections of the same course and were not strongly correlated with other achievement measures. In contrast to previous studies, we observed no significant gender differences. We suggest that instructor interventions based on early student performances with these simulations may assist students to recognize effective and efficient problem-solving strategies and enhance learning.

    2012-01-01

    In searching for dark skies, persistently clear weather, and minimal atmospheric interference, astronomical observing sites are generally located in remote, mountainous locations, and usually far from large communities. Such locations often have weak economies, and shallow workforce pools in the technical and administrative areas generally needed by the observatories. This leads to a problem, and an opportunity, for both the observatories and their local communities. Importing employees from far away locations is costly, leads to high turnover, and deprives the community of economic benefits and the sense of fealty with the observatories that would naturally result if local people occupied these comparatively good paying jobs. While by no means unique, the observatories on Mauna Kea Hawai`i are a clear example of this dual dilemma. This presentation will report findings from a model workforce needs assessment survey of all the Mauna Kea observatories, which has establish likely annual staffing requirements in several categories of technological and administrative support, including the educational entrance requirements. Results indicated that through 2023, 80% of observatory job openings on Hawai`i Island will be in technology and administration. Furthermore, the vast majority of these jobs will require only a two-year or four-year college degree in a relevant field as an entrance requirement. Efforts to realign the existing resources to better meet these common needs will be discussed, including the highly successful partnership between County of Hawai`i Workforce Development Board, the Mauna Kea observatories, the local K-12 systems, Hawai`i Community College, the University of Hawai`i Hilo, and a number of informal education and workplace experience programs. This collaboration has resulted in no fewer than three, interlocked, community programs have stepped up to meet this challenge to the benefit of both the local community and the observatories.

    It is widely recognised that uncontrolled discharge of petroleum products or other materials from offshore oil and gas exploration and production wells, and from associated industrial operations including treatment and service facilities that are required to be on or near the coast, can have direct and sometimes deleterious impacts on the marine environment. In mid-1992, the Australian Petroleum Exploration Association (APEA) commissioned five scientific reviews to examine the environmental implications of offshore petroleum developments in Australia. The reviews, carried out by an Independent Scientific Review Committee on behalf of the Australian Petroleum Exploration Association (APEA) and the Energy Research and Development Corporation (ERDC) deal with: (1) the preliminary geophysical exploration of the sea bed and underlying strata using seismic surveys, and especially the effects of bursts of underwater sound energy on biological communities; (2) the drilling of offshore wells, especially the disposal of drilling fluids and drill cuttings; (3) the production of oil and gas from proven wells, especially the disposal of large quantities of produced formation water (fossil water); (4) the construction and operation of coastal support facilities and associated activities which might have consequences for marine habitats; (5) oil spills associated with any of the above operations and especially the likely short- and long-term effects of an accidental oil spill on marine biota and on the aesthetic and commercial values of an impacted coastline. Comments on the findings are preceded by a brief summary of background information, relevant technologies and the main implications for the marine environment. Some suggestions are provided for possible future research, monitoring and environmental management. refs., figs., tabs

    The explosion of information communication technology (ICT) since the beginning of the 20th century has been rendering manual-based library system in academic, research, special and public libraries less relevant. This is because using and implementing information communication technology in the library depend largely on the librarian attitude toward the current digital age. This study examined the attitudinal correlates of some selected scientific and research institutes libraries in Irantowards the use and application of ICT in their various libraries. A total of ten libraries from all the forty nine libraries in Iran formed the studyís population. It is observed that 'Internet/intranet etc' (1046; 67.5%) is the most important source through which the users become aware of modern information technologies used in their libraries. The vast majority of the respondents who answered electronic sources make it 'Easier' to gather and use information are (1313; 84.7%). The results indicate that there is a significant relationship between e-environment and collection development (?262.86, p=0.000). Findings further show that all of librarians (9; 100%) opined they feel that ICT application affects the collection development of library. Based on these findings, it is recommended that libraries in the developing countries should consider training those librarians who do not have knowledge of ICT in order to remove the fear and anxiety hindering them from developing good attitude towards the use of ICT in their libraries.

    Competency in forms of scientific communication, both written and spoken, is essential for success in academic science. This study examined the psychometric properties of three new measures, based on social cognitive career theory, that are relevant to assessment of skill and perseverance in scientific communication. Pre- and postdoctoral trainees in biomedical science (N = 411) completed online questionnaires assessing self-efficacy in scientific communication, career outcome expectations, and interest in performing tasks in scientific writing, oral presentation, and impromptu scientific discourse. Structural equation modeling was used to evaluate factor structures and model relations. Confirmatory factor analysis supported a 22-item, 3-factor measure of self-efficacy, an 11-item, 2-factor measure of outcome expectations, and a 12-item, 3-factor measure of interest in scientific communication activities. Construct validity was further demonstrated by theory-consistent inter-factor relations and relations with typical communications performance behaviors (e.g., writing manuscripts, abstracts, presenting at national meetings).

    Angiogenesis is one of the prerequisite steps for viable tissue formation. The ability to influence the direction and structure in the formation of a vascular system is crucial in engineering tissue. Using biological laser printing (BioLP), we fabricated branch/stem structures of human umbilical vein endothelial cells (HUVEC) and human umbilical vein smooth muscle cells (HUVSMC). The structure is simple as to mimic vascular networks in natural tissue but also allow cells to develop new, finer structures away from the stem and branches. Additionally, we printed co-culture structures by first depositing only HUVECs, followed by 24 h incubation to allow for adequate cell-cell communication and differentiation into lumina; these cell printed scaffold layers were then removed from incubation and inserted into the BioLP apparatus so that HUVSMCs could be directly deposited on top and around the previously printed HUVEC structures. The growth and differentiation of these co-culture structures was then compared to the growth of printed samples with either HUVECs or HUVSMCs alone. Lumen formation was found to closely mimic the original branch and stem structure. The beginning of a network structure is observed. HUVSMCs acted to limit HUVEC over-growth and migration when compared to printed HUVEC structures alone. HUVSMCs and HUVECS, when printed in close contact, appear to form cell-cell junctions around lumen-like structures. They demonstrate a symbiotic relationship which affects their development of phenotype when in close proximity of each other. Our results indicate that it is possible to direct the formation and growth of lumen and lumen network using BioLP.

    During the past decades, many specialised networks have formed to meet specific radioecological objectives, whether regional or sectorial (purpose-oriented). Regional networks deal with an array of radioecological issues related to their territories. Examples include the South Pacific network of radioecologists, and the European network of excellence in radioecology. The latter is now part of the European platform for radiation protection. Sectorial networks are more problem-oriented, often with wider international representativeness, but restricted to one specific issue, (e.g. radioactive waste, low-level atmospheric contamination, modelling). All such networks, while often working in relative isolation, contribute to a flow of scientific information which, through United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR's) efforts of synthesis, feeds into the radiation protection frameworks of protecting humans and the environment. The IUR has therefore prompted a co-construction process aimed at improving worldwide harmonisation of radioecology networks. An initiative based on an initial set of 15 networks, now called the IUR FORUM, was launched in June 2014. The IUR Forum agreed to build a framework for improved coordination of scientific knowledge, integration and consensus development relative to environmental radioactivity. Three objectives have been collectively assigned to the IUR FORUM: (1) coordination, (2) global integration and construction of consensus and (3) maintenance of expertise. One particular achievement of the FORUM was an improved description and common understanding of the respective roles and functions of the various networks within the overall scene of radioecology R&D. It clarifies how the various networks assembled within the IUR FORUM interface with UNSCEAR and other international regulatory bodies (IAEA, ICRP), and how consensus on the assessment of risk is constructed.

    Full Text Available Purpose. Pharmaceutical industry is transnational and globally important. Many pharmaceutical companies operate their business in multinational and international forms in different countries. Diverse researches from different countries indicated and confirmed marketing promotion importance in pharmaceutical field. Therefore, marketing promotion and its effects are a very important issue that should be globally investigated in real life and evidence context. We oriented our research according to these scientific and practical values.Methodology. We reviewed pharmaceutical marketing promotion researches from more than 25 different countries, e.g., USA, Canada, Italy, France, Russia, India, Egypt and Syria where we employed our knowledge of three widely spread languages, i.e., English, Russian and Arabic. Such language variation supports us with large and variable amount of scientific knowledge, deep understanding and ability of analysis. Some studies investigated average response to pharmaceutical marketing promotion and few studies took into consideration heterogeneity in their effects with respect to advertising medium or drug characteristics.Originality. We investigated empirical evidences of pharmaceutical marketing promotion that can be directed to either consumer or healthcare professionals.Findings. We extracted, gathered and associated information of pharmaceutical promotion globally which oriented us to several evidence and practical facts with regard to employing promotion tools in different definite situations pertinent to main directions; their welfare and health enhancing effects and adverse effects. Practical Implications- Consequently, we developed practically-oriented guidelines for companies concerning pharmaceutical promotion globally ate the end of this paper.

  18. How does the scientific progress in developing countries affect bibliometric impact measures of developed countries? A counterfactual case study on China

    Many developed countries have found their bibliometric impact measures to be improving over the last decade. Also the BRICS states, the economically largest group of developing countries, observe a similar pattern. This uniform growth seems puzzling, as not every country can improve its relative performance to all other countries. A possible explanation for this uniform growth might be found in the dynamic environment and especially in the exponential growth of Chinese publications. We like to analyze how this unprecedented growth of contributions from a single country with its specific bibliometric characteristics affects the whole bibliometric measurement process. We show that due to the lowly cited Chinese publications the overall corpus of scientific publications grows especially in the lower tail and argue that this unequal increase in publications benefits especially the bibliometric impact measures of developed countries. The actual magnitude of this effect will be derived by contrasting the actual bibliometric world with a counterfactual one without China. (Author)

    In this report we describe theory and 3D full wave code description for the wave excitation, propagation and absorption in 3-dimensional (3D) stellarator equilibrium high beta plasma in ion cyclotron frequency range (ICRF). This theory forms a basis for a 3D code creation, urgently needed for the ICRF heating scenarios development for the operated LHD, constructed W7-X, NCSX and projected CSX3 stellarators, as well for re evaluation of ICRF scenarios in operated tokamaks and in the ITER . The theory solves the 3D Maxwell-Vlasov antenna-plasma-conducting shell boundary value problem in the non-orthogonal flux coordinates ({Psi}, {theta}, {var_phi}), {Psi} being magnetic flux function, {theta} and {var_phi} being the poloidal and toroidal angles, respectively. All basic physics, like wave refraction, reflection and diffraction are self consistently included, along with the fundamental ion and ion minority cyclotron resonances, two ion hybrid resonance, electron Landau and TTMP absorption. Antenna reactive impedance and loading resistance are also calculated and urgently needed for an antenna -generator matching. This is accomplished in a real confining magnetic field being varying in a plasma major radius direction, in toroidal and poloidal directions, through making use of the hot dense plasma wave induced currents with account to the finite Larmor radius effects. We expand the solution in Fourier series over the toroidal ({var_phi}) and poloidal ({theta}) angles and solve resulting ordinary differential equations in a radial like {Psi}-coordinate by finite difference method. The constructed discretization scheme is divergent-free one, thus retaining the basic properties of original equations. The Fourier expansion over the angle coordinates has given to us the possibility to correctly construct the ''parallel'' wave number k{sub //}, and thereby to correctly describe the ICRF waves absorption by a hot plasma. The toroidal harmonics are tightly

    Experts and practitioners agree that the quality of vocational high schools needs to be greatly improved. Many construction services have voiced their dissatisfaction with today's low-quality vocational high school graduates. The low quality of graduates is closely related to the quality of the teaching and learning process, particularly teaching materials. In their efforts to improve the quality of vocational high school education, the government have implemented Curriculum 2013 (K13) and supplied teaching materials. However, the results of monitoring and evaluation done by the Directorate of Vocational High School, Directorate General of Secondary Education (2014), the provision of tasks for students in the teaching materials was totally inadequate. Therefore, to enhance the quality and the result of the instructional process, there should be provided students' worksheets that can stimulate and improve students' problem-solving skills and soft skills. In order to develop worksheets that can meet the academic requirements, the development needs to be in accordance with an innovative learning approach, which is the soft skill-based scientific approach.

    1974-01-01

    Origin of spiral branches of galaxies and formation of stars in them are considered from the point of view of the theory of the gravitational gas condensation, one of comparatively young theories. Arguments are presented in favour of the stellar condensation theory. The concept of the star formation of gas is no longer a speculative hypothesis. This is a theory which assumes quantitative verification and explains qualitatively many facts observed. And still our knowledge on the nature of spiral branches is very poor. It still remains vague what processes give origin to spiral branches, why some galaxies have spirals and others have none. And shapes of spiral branches are diverse. Some cases are known when spiral branches spread outside boundaries of galaxies themselves. Such spirals arise exclusively in the region where there are two or some interacting galaxies. Only first steps have been made in the explanation of the galaxy spiral branches, and it is necessary to carry out new observations and new theoretical calculations

    An inventory of the test equipment of the AVM Branch ''Acoustic and Vibratory Mechanics Analysis Methods'' group has been undertaken. The purpose of this inventory is to enable better acquaintance with the technical characteristics of the equipment, providing an accurate definition of their functionalities, ad to inform potential users of the possibilities and equipment available in this field. The report first summarizes the various experimental surveys conduced. Then, using the AVM equipment database to draw up an exhaustive list of available equipment, it provides a full-scope picture of the vibration measurement systems (sensors, conditioners and exciters) and data processing resources commonly used on industrial sites and in laboratories. A definition is also given of a mobile test unit, called 'shelter', and a test bench used for the testing and performance rating of the experimental analysis methods developed by the group. The report concludes with a description of two fixed installations: - the calibration bench ensuring the requisite quality level for the vibration measurement systems ; - the training bench, whereby know-how acquired in the field in the field of measurement and experimental analysis processes is made available to others.

    Plants alter their development in response to changes in their environment. This responsiveness has proven to be a successful evolutionary trait. Here, we tested the hypothesis that two key environmental factors, light and nutrition, are integrated within the axillary bud to promote or suppress the growth of the bud into a branch. Using petunia (Petunia hybrida) as a model for vegetative branching, we manipulated both light quality (as crowding and the red-to-far-red light ratio) and phosphate availability, such that the axillary bud at node 7 varied from deeply dormant to rapidly growing. In conjunction with the phenotypic characterization, we also monitored the state of the strigolactone (SL) pathway by quantifying SL-related gene transcripts. Mutants in the SL pathway inhibit but do not abolish the branching response to these environmental signals, and neither signal is dominant over the other, suggesting that the regulation of branching in response to the environment is complex. We have isolated three new putatively SL-related TCP (for Teosinte branched1, Cycloidia, and Proliferating cell factor) genes from petunia, and have identified that these TCP-type transcription factors may have roles in the SL signaling pathway both before and after the reception of the SL signal at the bud. We show that the abundance of the receptor transcript is regulated by light quality, such that axillary buds growing in added far-red light have greatly increased receptor transcript abundance. This suggests a mechanism whereby the impact of any SL signal reaching an axillary bud is modulated by the responsiveness of these cells to the signal. © 2015 American Society of Plant Biologists.

    The main purpose of a study is its publication on a scientific journal. Research financing agencies are important institutions so that studies can be developed and published. The most important research financing agencies that are discussed in this article are: "Coordenação de Aperfeiçoamento de Pessoal de Nível Superior" (CAPES), "Conselho Nacional de Desenvolvimento Científico e Tecnológico" (CNPq) and "Fundação de Amparo à Pesquisa do Estado de São Paulo" (FAPESP). CAPES' activities can be grouped in four different strategy lines: a) it evaluates the stricto sensu, at the post-graduation level; b) it provides access and development of scientific research; c) it provides investment on the development of high qualified human resources in Brazil and abroad, and d) it promotes international scientific cooperation. Although CAPES does not support directly scientific publications, almost all actions of this agency contribute to the development of scientific research and publication. CNPq has two main purposes: financing researches and development of human resources. It provides the researchers with financial aid to scientific publication. The grants for editing were specifically created for supporting the national scientific and technical publications edited by Brazilians institutions or societies. CNPq can also support Congresses, Symposiums and similar short-term courses. The Plataforma Lattes is also a branch of CNPq on which the Curriculum Lattes is available. This site has the curriculum vitae of the scientific community and is of great value for researchers. FAPESP also finances journal publications, articles and books that bring up original results of studies made by researchers from the state of São Paulo. It finances, partially, the travel expenses of innovative papers authors in meetings within the country or abroad. Brazilian authors are increasing the number of international publications.

    Full text of publication follows: The crystallochemical phosphate concept in question is developed successfully in the new pyro-electrochemical reprocessing technology of irradiated fuel in molten chlorides of alkaline elements at one of the leading scientific nuclear centers - Research Institute of Atomic Reactors. Irradiated fuel is dissolved in molten chlorides of alkaline elements by mean of treating by chlorine. Then uranium and plutonium dioxides are removed electrochemically. The melt, when used many times, is contaminated by the residual actinide and contains fission products and the so called 'process' elements. This melt is unacceptable for future use. Phosphate methods can be applied for the solution of the following tasks: a) reprocessing (purification) of molten chloride salt solvents; b) conversion of the spent chloride melts to the insoluble stable crystalline product for safe storage and disposal. Within the framework of task 'a' phosphate methods may be realized by the several ways: 1) phosphate concentrating of impurities and their extraction from molten chlorides into solid phase by mean of chemical precipitation, co-precipitation, ion exchange and other chemical interactions, 2) conversion of precipitated waste phosphates to stable crystalline phosphate powders or ceramics for safe storage and disposal.

    Full Text Available A teacher training program, named Model-Supported Scientific Inquiry Training Program (MSSITP has been successfully developed to improve the inquiry skills of Indonesian elementary teachers. The skills enhanced by MSSITP are defining problems, formulating hypotheses, planning and doing investigations, drawing conclusions, and communicating the results. This teacher training program was evaluated by 48 teachers selected by stratified random sampling technique from 48 elementary schools in Bandar Lampung City, Lampung Province, Indonesia. The program was designed to follow Bandura’s stages of social learning: attention, retention, production, and motivation. The impact of MSSITP was evaluated in three ways. First, by analyzing the improvements of inquiry skills compared to conventional SITP through pretest and posttest control group design. Second, by using an inquiry questionnaire to describe teachers’ perceptions of inquiry learning. Last, by using a response instrument to elicit teachers’ opinions of the program. The results indicate a significant difference (sig 0.00 in teachers’ skills acquired from the two different training programs. Mean posttest scores, varying from 34.7 to 56.9 for the control group and 58.3 to 98.6 for the experimental group, confirmed the effectiveness of MSSITP.

    2017-08-01

    Full Text Available The lack of knowledge about grow dynamics of the living tree crown of Nothofagusobliqua secondary growth forests strongly limits the objective formulation of silvicultural schemes oriented to the industrial production of high quality wood. Therefore, in this work, we described basic relationships between tree size, age and angle branches insertion and the crown. Considering a sample data of 59 dominant trees, distributed in different age conditions, we applied a combined analysis technique of stem analysis, steam taper analysis and thickest branch measurement in each decile of the total height. This approach allowed us to determine that there is a significant relationship between the steam diameter, the angle insertion and the age of the branch, as well as the size and age of the trees. Also, the thicker branches tend to have lower insertion angles, to be older, to be located at lower relative heights and to be located in larger diameter sections. Taking into consideration these relationships, it is possible to build new predicted branch models as tools for the development of silvicultural schemes to suit different log grade.

    The scheme of chemical processes proceeding in the active medium of a pulsed chemical oxygen-iodine laser (COIL) is analysed. Based on the analysis performed, the complete system of differential equations corresponding to this scheme is replaced by a simplified system of equations describing in dimensionless variables the chain dark decomposition of iodides - atomic iodine donors, in the COIL active medium. The procedure solving this system is described, the basic parameters determining the development of the chain reaction are found and its specific time intervals are determined. The initial stage of the reaction is analysed and criteria for the development of the branching chain decomposition reaction of iodide in the COIL active medium are determined. (active media)

  14. Branch formation induced by microbeam irradiation of Adiantum protonemata

    Branches were induced in centrifuged Adiantum protonemal cells by partial irradiation with polarized red light. Nuclear behavior and microtubule pattern change during branch formation were investigated. A branch formed at any part where a red microbeam was focused along a long apical cell. The nucleus moved towards the irradiated area and remained there until a branch developed. The pattern of microtubules changed from parallel to oblique at the irradiated area and then a transverse arrangement of microtubules appeared on both sides of the area. It appeared as if the nucleus was suspended between two microtubule rings. This nuclear behavior and the changes in microtubule pattern were different from those observed during branch formation under whole cell irradiation. From the results of this work we suggest that there is an importance for precise control of experimental conditions

    Full Text Available The article presents the results of the scenario simulation of scientific and innovative development of Ukraine to determine the appropriate method of its management under conditions of a new industrial revolution and association with the EU. It is shown that the best scenario that in the long run provides a significant improvement in the results of scientific and technological development is a scenario of increasing the level of R&D expenditures to the EU target figure amounting to 4% of GDP. But this scenario is unlikely. It is found that the optimal level of expenditures can be considered as 2.5% of GDP, which can be achieved in the medium term; in this case raising the level of expenditures to 1.7-2% of GDP gives certain results but does not produce sufficient resources for a long-term development. It is proved that in order to achieve significant results in scientific and technological development, the increase in expenditures on R&D should be accompanied by forming clusters, increasing the level of protection of investors, providing development of high-tech industries and employment in this sphere, as well as facilitating the access to ICTs. It is found that a prerequisite for an effective scientific and technological development is stimulation of the population interest in obtaining high-quality professional education, including through the promotion by employers.

    The practice of science and engineering is being revolutionized by the development of cyberinfrastructure for accessing near real-time and archived observatory data. Large cyberinfrastructure projects have the potential to transform the way science is taught in high school classrooms, making enormous quantities of scientific data available, giving students opportunities to analyze and draw conclusions from many kinds of complex data, and providing students with experiences using state-of-the-art resources and techniques for scientific investigations. However, online interfaces to scientific data are built by scientists for scientists, and their design can significantly impede broad use by novices. Knowledge relevant to the design of student interfaces to complex scientific databases is broadly dispersed among disciplines ranging from cognitive science to computer science and cartography and is not easily accessible to designers of educational interfaces. To inform efforts at bridging scientific cyberinfrastructure to the high school classroom, Education Development Center, Inc. and the Scripps Institution of Oceanography conducted an NSF-funded 2-year interdisciplinary review of literature and expert opinion pertinent to making interfaces to large scientific databases accessible to and usable by precollege learners and their teachers. Project findings are grounded in the fundamentals of Cognitive Load Theory, Visual Perception, Schemata formation and Universal Design for Learning. The Knowledge Status Report (KSR) presents cross-cutting and visualization-specific guidelines that highlight how interface design features can address/ ameliorate challenges novice high school students face as they navigate complex databases to find data, and construct and look for patterns in maps, graphs, animations and other data visualizations. The guidelines present ways to make scientific databases more broadly accessible by: 1) adjusting the cognitive load imposed by the user

    Full Text Available O trabalho discute a relação entre a comunidade científica, o Estado e a universidade no contexto atual do desenvolvimento científico-tecnológico. Enfatiza a dimensão política das transformações recentes, sobretudo no tocante aos sistemas decisórios, contrapondo momento mais verticalizado com cenário mais democratizado, e as conseqüências das transformações políticas contemporâneas, na sociedade brasileira. Procura analisar as mútuas correlações entre o Estado, as universidades e as comunidades científicas, a partir do entendimento da especificidade de cada um destes atores na condução do desenvolvimento científico-tecnológico nacional. A esse respeito, é analisado todo um conjunto de ações que se coadunam com o novo modo de produção do conhecimento, buscando destacar a natureza controversa e polêmica da inserção do Estado e o caráter conservador da comunidade científica, bem como a resistência da universidade na proposição de novas linhas de atuação no enfrentamento dos desafios trazidos pela ciência e tecnologias contemporâneas.This article discusses the relationship between scientific community, the State and university in the current circumstances of scientific-technological development. It stresses the political dimension of recent changes, specially regarding decision systems, comparing a more vertical moment and a more democratic scenario and the consequences of contemporary political changes in Brazilian society. It examines mutual relations between the State, universities and the scientific community, based on the understanding of each of those actors' specificities in advancing national scientific-technological development. A whole set of actions is examined in accordance with knowledge's new mode of production in order to highlight the controversial nature of the State and the conservative character of the scientific community as well as the resistance of the university in proposing new lines
