    Full Text Available Malaysia is considered an active key player in information communication technologies (ICTs especially in education. In fact, in the National Higher Education Strategic Plan, one of the Critical Agenda Projects (CAPs of the Minister of Higher Education is e-learning. It goes without saying that all higher learning providers in Malaysia must be prepared to provide state-of-the-art facilities for the students. One critical aspect of e-learning is the quality and quantity of the content, or what will be referred by many scholars as e-content. This paper attempts to identify the challenges of content development for e-learning practice at the National Defence University of Malaysia (NDUM. It is crucial to investigate this issue since the university just purchased its Learning Management System (LMS. It is expected that resistance will be present as the academics at the defence university is a mixture of junior and senior lecturers, as well as civilian and military lecturers; and some of these academics have been teaching without the assistance of e-learning. In so doing, the methodology of this paper will mainly be content analysis of various reports, governmental documents, as well as semi-structured interviews with lecturers at the NDUM. As this paper acts as a preliminary investigation into the issue of e-content at the university, only seven lecturers were interviewed. Initial findings suggest that there are basically five challenges of developing e-content at the NDUM. These include the lack of ICT and e-learning policy that can provide guidelines to academics; the uncertainty of ownership for e-learning initiatives; the lack of understanding of the roles of e-learning; the lack of awareness on e-learning; and the difficulties to develop military based content due to confidentiality issues. Two possible solutions for these challenges are also examined which take into consideration the urgent need to set up an e-Learning Unit and to provide

  4. LSDS Development for Isotopic Fissile Content Assay

    International Nuclear Information System (INIS)

    Concerning the sustainable energy supply and green house effect, nuclear energy became the most feasible option to meet the energy demand in Korea. However, the production of the spent nuclear fuel is the inevitable situation. Since the first nuclear power plant started to produce the electricity in Korea, the accumulated amount of spent fuels exceeded 10k tomes recently. The accumulation of the spent fuels is the big issue in the society. Therefore, as an option which strengthens the nuclear proliferation resistance and reduces the amount of spent fuels, sodium fast reactor (SFR) program linked with pyro-processing is under development to re-use the PWR spent fuel and produce the energy. In the process, the produced metallic material involves uranium and TRU (transuranic; neptunium, plutonium, and americium). The uranium-TRU is used to fabricate SFR fuel. The burning the recycled fuel in the reactor is to solve the current spent fuel storage problem and to minimize the actinides accumulation having long half-life. Generally, the spent fuel from PWR has unburned ∼1 % U235, produced ∼0.5 % plutonium from decay chain, ∼3 % fission products, ∼ 0.1 % minor actinides (MA) and uranium remainder. About 1.5 % fissile materials still exist in the spent fuel. Therefore, spent fuel is not only waste but energy resource. The direct and isotopic fissile content assay is the crucial technology for the spent fuel reuse. Additionally, the fissile content analysis will contribute to the optimum storage design and safe spent fuel management. Several nondestructive technologies have been developed for the spent fuel assay; gamma ray measurement, passive and active neutron measurements. Spent fuel emits intense gamma rays and neutrons by (a, n) and spontaneous fission. This intense background has the limitation on the direct analysis of fissile materials. Recently, to analyze the individual fissile content, leadslowing down spectrometer (LSDS) has been being developed in Korea

    The Development and Evolution of the Idea of the Mandate of Heaven in the Zhou Dynasty The changes in the idea of Mandate of Heaven during the Shang and Zhou dynasties are of great significance in the course of the development of traditional Chinese culture. The quickening and awakening of the humanistic spirit was not the entire content of the Zhou idea of Mandate of Heaven. In the process of annihilating the Shang dynasty and setting up their state, the Zhou propagated the idea of the Mandate of Heaven out of practical needs. Their idea of the Mandate of Heaven was not very different from that of the Shang. From the Western Zhou on, the Zhou idea of Mandate of Heaven by no means developed in a linear way along a rational track. The intermingling of rationality and irrationality and of awakening and non-awakening remained the overall state of the Zhou intellectual superstructure after their "spiritual awakening".

    The integration of medical informatics and e-learning systems could provide many advanced applications including training, knowledge management, telemedicine, etc. Currently, both the domains of e-learning and medical image have sophisticated specifications and standards. It is a great challenge to bring about integration. In this paper, we describe the development of a Web interface for searching and viewing medical images that are stored in standard medical image servers. With the creation of a Web solution, we have reduced the overheads of integration. We have packaged Digital Imaging and Communications in Medicine (DICOM) network services as a component that can be used via a Web server. The Web server constitutes a content repository for searching, editing, and storing Web-based medical image content. This is a simple method by which the use of Picture Archiving and Communication System (PACS) can be extended. We show that the content repository can easily interact and integrate with a learning system. With the integration, the user can easily generate and assign medical image content for e-learning. A Web solution might be the simplest way for system integration. The demonstration in this paper should be useful as a method of expanding the usage of medical information. The construction of a Web-based repository and integrated with a learning system may be also applicable to other domains. PMID:16710797

    CDC designed its Health Systems Integration Program to prepare leaders to function at the interface of public health and health care. Specific Health Systems Integration Program competencies in the areas of communication, analysis and assessment, and health systems were developed to nurture evidence-based decision-making and leadership skills crucial for future public health leaders. The program therefore designed an innovative journal club as part of its competency-based curriculum not only to meet the standard goals for a journal club-critical reading, interpretation, and acquiring content knowledge-but also to foster leadership development. This report describes the Health Systems Integration Program journal club format, its implementation, challenges, and key elements of success. Other programs using a journal club model as a learning format might consider using the Health Systems Integration Program's innovative approach that focuses on leadership development. PMID:25439249

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

    Full Text Available Integration of information and communication technology into other than Information Technology subjects taught at schools of all levels in the Czech Republic has become of great importance. As schools are equipped with information and communication technology (ICT much better than ever before researchers have focused on the way they are used in the classes. Development of technology is fast and not all teachers from schools have undergone education on how to integrate technology into the teaching process. These are the reasons why it is necessary to find a system for training teachers in this field. We provided such a training course for secondary school English teachers. This article brings information about the impact of this course on one model teacher’s lessons. A questionnaire, which was specially developed for the purpose of evaluating technological pedagogical content knowledge (TPACK, is introduced in this article. It assesses the TPACK development perceived by the teacher. We describe in detail how the new knowledge and skills reflect in her teaching. The results are demonstrated on the Technological pedagogical content knowledge framework.

    Research Articles A Reflection on the Militarization of Sparta Hongjun(4) In Western academic history, the view that ancient Sparta was a militarist state or a state with strong militarist features has always been an influential one. This view first appeared in Greece of the 4th century BC and has continued to the present day. But objectively speaking Western scholars have, to varying degrees, been in error on this point, both in theory and in the use of historical materials. To judge whether a state is militarist, we must give comprehensive consideration to its institutions, policies, internal affairs and diplomacy. According to this criterion, Sparta was not a militarist state until the mid-Sth century BC. Its militarization began in the sixties of the fifth century BC and was established by the thirties. However, ancient Sparta did not establish a totalitarian state system and did not develop into a typical militarist state in the modern sense

    Social science has long been confronted with a problem of identity, as a branch of social science, the development of Public Administration is also influenced by this problem. Before 1930s, public administration researchers held a scientific belief identical with other social scientists, and took the establishment of a administrative science as their mission; after 1930s, the finding of Hawthorne Experiment greatly wavered the scientific' belief of public administration researchers, which contributed to the bankruptcy of the politics-administration dichotomy; in the 1950s, while public administration researchers in whole had abandoned the dichotomy, social scientists as a whole had rejoined the embrace of scientific pursuit, which produced a huge tension within public administration researchers. Since then, the community of public administration researchers had differentiated into two antithetical camps.

    Science.gov (United States)

    Husson, J. M.; Dubois, F.; Sauvat, N.

    2010-05-01

    Creep evolution of timber structures results from the interaction between mechanical stresses due to different loads and hydric stresses due to moisture content variations. This paper deals with a thermodynamic approach in order to take into account a realistic elastic behavior under moisture content variations. In this context, memory effect, experimentally observed, is introduced employing a mechano-sorptive stress driven by a function dependent of the moisture content variations. This new internal thermodynamic variable enables to define an original separation of the free energy into an instantaneous recoverable part and a stored part during the last drying phase. This energy enables the modeling of the nonreversible strain process during the unloading phase. The locate state method is employed in order to define the thermodynamic function which traduces an indirect hereditary behavior between moisture content history and the stress state in the material.

  6. High-content neurite development study using optically patterned substrates.

    Directory of Open Access Journals (Sweden)

    Jonathan M Bélisle

    Full Text Available The study of neurite guidance in vitro relies on the ability to reproduce the distribution of attractive and repulsive guidance molecules normally expressed in vivo. The identification of subtle variations in the neurite response to changes in the spatial distribution of extracellular molecules can be achieved by monitoring the behavior of cells on protein gradients. To do this, automated high-content screening assays are needed to quantify the morphological changes resulting from growth on gradients of guidance molecules. Here, we present the use of laser-assisted protein adsorption by photobleaching (LAPAP to allow the fabrication of large-scale substrate-bound laminin-1 gradients to study neurite extension. We produced thousands of gradients of different slopes and analyzed the variations in neurite attraction of neuron-like cells (RGC-5. An image analysis algorithm processed bright field microscopy images, detecting each cell and quantifying the soma centroid and the initiation, terminal and turning angles of the longest neurite.

    Full Text Available 21st century demands the incorporation of ICT skills as a crucial component in developing a 21st century learner. For doing so the teacher must be capable to implement and create such an environment to develop such skills among the earners. In order to produce effective teachers with 21st century skills the teacher educators must be competent to develop a 21st century teacher and must themselves be a 21st century teacher educator. Though ICT has been integrated within the curriculum of teacher education in India the practical exposure to effectively use technology in education within and outside a classroom is still yet to pick up pace. This paper illustrates a training module provided for the trainee teachers to develop a video based instruction of experiments in Biology. The module had a positive and an effective impact among trainee teachers.

  11. Development of requirements management system of NUMO and practical experience with development of the database contents

    International Nuclear Information System (INIS)

    Decision-making and work activities in the geological disposal program need to be implemented in such a way as to fulfill various requirements such as safety, engineering feasibility, quality and socio-economic aspects. Since a stepwise approach is applied for implementing the program, the number, weighting and specific nature of the requirements will change depending on the premises and constraints in each stage of implementation. Requirements management with a long-term perspective is therefore required for consistent implementation of the program. NUMO has developed a requirements management (RM) methodology that is suitable for the long-term, stepwise disposal program in Japan, as well as a supporting requirements management system (RMS) tool. The basic concept of the RMS was already presented at the last ICEM 2009. In this presentation, we will focus on practical experience with development of the database content for the RMS. (author)

    Full Text Available Education is an important component of any nation’s development process. Society has been credited with creating technology, but technology is simultaneously creating society. One of the key benefits of such technology creation includes learning and curriculum development, which is otherwise referred to as e-leaning, and more appropriately referred to as global e-learning. Global e-learning raises some implications, which include communication, culture, and technology, that must be addressed before successful implementation and outcome can occur. In this paper, we discuss cultural related issues such as culture influence on e-learning and the dimensions of cultural variability. In addition, we present the main challenges to provide e-learning opportunities. Finally, a case study for facing the cultural challenges is presented; this will be followed by concluding remarks at the end of this paper.

    Full Text Available The objective of this study is to review the international marketing literature on new product development process and compare the changes in the important factors in the process with the changes in the management approaches. For this purpose, the articles in three international marketing journals were selected and “new product development” and “new product performance” were searched for in the abstracts. After grouping the variables in the process, they were compared with the perspectives of management in the related periods. The results indicated that organizational factors have always been important for new product development process, which is in line with the nature of the innovation process. But the emphasis on internal factors has increased in the 21st century which is congruent with the change in management perspective foregrounding resource based view. The study differs from the similar literature review studies on the point that it deals with the topic from international marketing perspective. Therefore, R&D and other marketing studies are not included in the review and the study proposes the important factors from international firms’ point of view.

    Full Text Available Revolutionary advancements have been observed in e-learning technologies though an amalgamated evaluation methodology for new generation e-learning content development tools is not available. The evaluation of educational software for online use must consider its usability and as well as its pedagogic effectiveness. This study is a first step towards the definition of criteria for evaluating e-learning tools. A preliminary user study involving a group of pre-service instructional designers, observed during their interaction with e-learning tools, is reported. Throughout the study, specific usability attributes of these e-learning tools were identified. Participants were assigned to rate the importance of functional and pedagogical competences proposed during the criteria development phase. The findings of the study revealed 31 evaluation criteria under the headings of technical, media, and assessment competences. Among the groups of benchmarks proposed and rated by the users, assessment was considered as the most important one while technical and media features were even.The following step was actual implemention of the usability criteria into evaluation of fifteen leading software used in e-learning across the world. Mostly, tools were observed as having limitations in terms of capabilities. Comparing to the other software, Captivate, Softchalk, and Lectora were regarded as outstanding tools by the participants. Following the discussion on the limitations of the study, some implications for further research were proposed.

This article attempts to give an overview of the content validity process and to explain the complexity of this process by introducing an example. Methods: We carried out a methodological study conducted to examine the content validity of the patient-centered communication instrument through a two-step process (development and judgment. At the first step, domain determination, sampling (item generation and instrument formation and at the second step, content validity ratio, content validity index and modified kappa statistic was performed. Suggestions of expert panel and item impact scores are used to examine the instrument face validity. Results: From a set of 188 items, content validity process identified seven dimensions includes trust building (eight items, informational support (seven items, emotional support (five items, problem solving (seven items, patient activation (10 items, intimacy/friendship (six items and spirituality strengthening (14 items. Content validity study revealed that this instrument enjoys an appropriate level of content validity. The overall content validity index of the instrument using universal agreement approach was low; however, it can be advocated with respect to the high number of content experts that makes consensus difficult and high value of the S-CVI with the average approach, which was equal to 0.93. Conclusion: This article illustrates acceptable quantities indices for content validity a new instrument and outlines them during design and psychometrics of patient-centered communication measuring instrument.

    2008-01-01

    Student content knowledge and general reasoning abilities are two important areas in education practice and research. However, there hasn't been much work in physics education that clearly documents the possible interactions between content learning and the development of general reasoning abilities. In this paper, we report one study of a systematic research to investigate the possible interactions between students' learning of physics content knowledge and the development of general scientific reasoning abilities. Specifically, this study seeks to answer the research question of whether and to what extent content learning may affect the development of general reasoning abilities. College entrance testing data of freshman college students in both USA and China were collected using three standardized tests, FCI, BEMA, and Lawson's Classroom Test of Scientific Reasoning (Lawson Test). The results suggest that years of rigorous training of physics knowledge in middle and high schools have made significant impac...

  8. Development of methods for determination of PAH based on measured CO-content

    International Nuclear Information System (INIS)

    The aim of the project 'Development of methods for determination of PAH based on measured CO-content' is to investigate the possibility to develop a method for continuous optimisation of NOx-emissions by decreased air ratio, without significant increase of polyaromatic hydrocarbons such as PAH. The general idea has been to find a indirect online method to predict the emissions of heavier hydrocarbons by: - creating a correlation between the content of CO and PAH, - controlling the air ratio by the CO-content, and - integrating the calculated PAH-content from CO-content. Today many boilers are operated with a low air ratio to minimise the NOx content and the NOx-fee. A low ratio increases the risk of high CO contents in the flue gas as well as increased contents of VOC and PAH. Other boilers are operated with high air ratios in order to minimise the CO content, which in some cases will result in unnecessary high NOx emissions. One of the main difficulties in optimising the air ratio to the most environmental friendly level is the lack of a suitable and well proven PAH instrument. There are today no available instruments for instantaneous and continuous measurement of PAH. PAH is normally measured as an average value during a period of at least one hour. It is not possible to detect short peaks. The development of the CO-method has been based on data from a CFB-boiler in Korsta in Sundsvall (Vaermeforskrapport 541). The data shows a clear correlation between THC and CO. The correlation seems to be mostly dependent of moisture content and load. The development presented in the report shows that it is possible to find a method to predict the PAH content from the CO-content in the flue gas. The next phase aims to improve and implement the method, by measurements and adaptation in a plant. The practical use of the method is as a tool to optimise the emission of CO, NOx, THC and PAH and/or to predict the PAH-emission during continuous operation

    Full Text Available Abstract Background Recent evidence has highlighted deficiencies in clinical trial protocols, having implications for many groups. Existing guidelines for randomized clinical trial (RCT protocol content vary substantially and most do not describe systematic methodology for their development. As one of three prespecified steps for the systematic development of a guideline for trial protocol content, the objective of this study was to conduct a three-round Delphi consensus survey to develop and refine minimum content for RCT protocols. Methods Panellists were identified using a multistep iterative approach, met prespecified minimum criteria and represented key stakeholders who develop or use clinical trial protocols. They were asked to rate concepts for importance in a minimum set of items for RCT protocols. The main outcome measures were degree of importance (scale of 1 to 10; higher scores indicating higher importance and level of consensus for items. Results were presented as medians, interquartile ranges, counts and percentages. Results Ninety-six expert panellists participated in the Delphi consensus survey including trial investigators, methodologists, research ethics board members, funders, industry, regulators and journal editors. Response rates were between 88 and 93% per round. Overall, panellists rated 63 of 88 concepts of high importance (of which 50 had a 25th percentile rating of 8 or greater, 13 of moderate importance (median 6 or 7 and 12 of low importance (median less than or equal to 5 for minimum trial protocol content. General and item-specific comments and subgroup results provided valuable insight for further discussions. Conclusions This Delphi process achieved consensus from a large panel of experts from diverse stakeholder groups on essential content for RCT protocols. It also highlights areas of divergence. These results, complemented by other empirical research and consensus meetings, are helping guide the development of

    Chávez, Óscar; Papick, Ira; Ross, Daniel J.; Grouws, Douglas A.

    2011-12-01

    This article describes the process of development of assessment instruments for a three-year longitudinal comparative study that focused on evaluating American high school students' mathematics learning from two distinct approaches to content organization: curriculum built around a sequence of three full-year courses (Algebra 1, Geometry, and Algebra 2) and a sequence of integrated mathematics courses (algebra and geometry content, together with functions, data analysis, and discrete mathematics is integrated each year). The study was conducted in six school districts in five states involving over 4,000 students from schools that were using both curricular approaches but with different groups of students. In order to develop assessment instruments that were not biased towards either of the two curriculum programs (Fair Tests), an iterative process of content analyses, identification of common topics, internal and external reviews, pilot tests, and revisions was followed, resulting in five tests that were used in the three years of the study. Results indicate that these tests have solid discrimination properties and address adequately mathematics content common to both secondary curriculum programs. The corresponding scoring rubrics are highly reliable, with interrater reliability above 94% for all tests. Mathematics education researchers involved in curriculum comparison studies need to conduct content analyses of the curriculum materials under study in order to identify salient relationships between curriculum programs and student outcomes.

    The sulfur-reducing functional component-the Lewis acid-base pair compound-and associated active zeolite component were developed to prepare the RFCC catalyst DOS for reducing sulfur content in gasoline.The results of catalyst evaluation have revealed that the Lewis acid-base pair compound developed hereby could enhance the conversion of macromolecular sulfur compounds by the catalyst to promote the proceeding of desulfurization reactions,and the synergetic action of the selected zeolite and the Lewis acid-base pair compound could definitely reduce the olefins and sulfur contents in gasoline.The heavy oil conversion capability of the catalyst DOS thus developed was higher coupled with an enhanced resistance to heavy metals contamination to reduce the sulfur content in gasoline by over 20%.The commercial application of this catalyst at the SINOPEC Jiujiang Branch Company has revealed that compared to the GRV-C catalyst the oil slurry yield obtained by the catalyst DOS was reduced along with an improved coke selectivity,an increased total liquid yield,and a decreased olefin content in gasoline.The ratio of sulfur in gasoline/sulfur in feed oil could be reduced by 20.3 m%.

  5. The impact of professional development in informal science contexts on teachers' content knowledge and discourse

    Holliday, Gary M.

    The Contextual Model of Learning (CML; Falk & Dierking, 1992, 2000) and reform documents have emphasized the unique learning environments that ISIs provide and the social aspects of that learning. As a result, individuals are able to use "each other as vehicles for reinforcing beliefs and meaning making" (Kisiel, 2003, p. 3). This study looked at two science content courses that were taught over two years by education staff of a large science and technology museum located in the Midwest. Data from six courses, with 187 participating elementary and middle school teachers, included content tests, portfolios and graduate credit assignments, daily and final evaluations of the course, as well as audio and video recordings of teachers while they were interacting with exhibits or engaged in an exhibit related activity. Results of this study found that PD educators' use of exhibits during both courses did not fully take into account the sociocultural context of CML and did not incorporate opportunities for discourse into the course instruction. However, when PD staff did make explicit connections between exhibits, science content, and activities, participants were more likely to be involved in in-depth, content related and pedagogical conversations while engaged in the courses. At the same time, even though teachers were very satisfied with the courses and felt that PD staff was effective in their instruction, participating teachers did not increase their science content knowledge even when explicit content connections were made to exhibits. It was unclear what outcomes the PD educators expect or want for their teacher students other than relaying content in a didactic manner (which was a secondary concern), sparking an interest in science, and providing many hands-on activities to bring back to the classroom. There is a need for a standardized professional development program for ISI educators and a need for restructuring ISI professional development so that it will

    Full Text Available The aim of this work was to evaluate spices and industrial ingredients for the development of functional foods with high phenolic contents and antioxidant capacity. Basil, bay, chives, onion, oregano, parsley, rosemary, turmeric and powdered industrial ingredients (β-carotene, green tea extract, lutein, lycopene and olive extract had their in vitro antioxidant capacity evaluated by means of the Folin-Ciocalteu reducing capacity and DPPH scavenging ability. Flavonoids identification and quantification were performed by High Performance Liquid Chromatography (HPLC. The results showed that spices presented a large variation in flavonoids content and in vitro antioxidant capacity, according to kind, brand and batches. Oregano had the highest antioxidant capacity and parsley had the highest flavonoid content. The industrial ingredient with the highest antioxidant capacity was green tea extract, which presented a high content of epigalocatechin gallate. Olive extract also showed a high antioxidant activity and it was a good source of chlorogenic acid. This study suggests that oregano, parsley, olive and green tea extract have an excellent potential for the development of functional foods rich in flavonoids as antioxidant, as long as the variability between batches/brands is controlled.

  8. Virginia physical science teachers' content knowledge assessment and professional development preferences

    Science.gov (United States)

    Hendrick, M. Georgeann

    The course content for middle school physical science in Virginia is defined by the Standards of Learning. These eleven categories include topics in scientific experimentation, the nature of matter, chemistry and physics. Content knowledge is essential if teachers are to provide effective teaching, which includes analogies, illustrations, examples, and most importantly, hands-on experimentation. One means of assessing teacher content knowledge is by determining their academic major and minor. Teachers lacking a major or minor in the classes they teach are defined as "out-of-field" by Ingersoll (1996). When he examined data for middle school physical science teachers, 74% were "out-of-field." This survey study had two major facets. First, Virginia teachers were asked to assess their content knowledge in all eleven categories. They were also asked to provide descriptive and demographic data about themselves (including their academic degrees) and their schools. Secondly, the teachers were asked for their professional development preferences as well as organizational logistics including location, time, other participants, and use of technology. The survey was mailed to each school containing an eighth grade within the Commonwealth. The survey response rate was 73%. The data was analyzed descriptively and analytically, using frequency, percentages, T-tests, and ANOVA. Three major findings emerged. (1) The three areas which teachers assessed as lowest content knowledge included PS.11 (Electricity and Magnetism), PS.9 (Light), and PS.8 (Sound). These exactly match the three topics most desired for professional development. (2) Based on Ingersoll's definition, 68% of Virginia's teachers are providing "out-of-field" instruction. In addition, teachers with fewer years of teaching experience or mixed assignments, and/or those teaching in smaller, more rural schools report lower content knowledge. (3) Teachers desire professional development in all eleven categories. They are

    Full Text Available Abstract Background Involving stakeholders and consumers throughout the content and study design ensures interventions are engaging and relevant for end-users. The aim of this paper is to present the content development process for a mHealth (mobile phone and internet-based cardiac rehabilitation (CR exercise intervention. Methods An innovative mHealth intervention was developed with patient input using the following steps: conceptualization, formative research, pre-testing, and pilot testing. Conceptualization, including theoretical and technical aspects, was undertaken by experts. For the formative component, focus groups and interviews with cardiac patients were conducted to discuss their perceptions of a mHealth CR program. A general inductive thematic approach identified common themes. A preliminary library of text and video messages were then developed. Participants were recruited from CR education sessions to pre-test and provide feedback on the content using an online survey. Common responses were extracted and compiled. An iterative process was used to refine content prior to pilot testing and conduct of a randomized controlled trial. Results 38 CR patients and 3 CR nurses participated in the formative research and 20 CR patients participated in the content pre-testing. Participants perceived the mHealth program as an effective approach to inform and motivate patients to exercise. For the qualitative study, 100% (n = 41 of participants thought it to be a good idea, and 11% of participants felt it might not be useful for them, but would be for others. Of the 20 participants who completed the online survey, 17 out of 20 (85% stated they would sign up to a program where they could receive information by video messages on a website, and 12 out of 20 (60% showed interest in a texting program. Some older CR patients viewed technology as a potential barrier as they were unfamiliar with text messaging or did not have mobile phones. Steps to

    International Nuclear Information System (INIS)

    We discuss our experiences and successes with the new 'Book Sprint' methodology for use in rapid authoring and content development for technical books and documentation, using a distributed team and appropriate on-line collaborative technologies. A sprint begins by assembling a group of domain experts for a short period of time-intensive content creation. The outline, scope, and approximate length of the book are established, and key contributors are identified. This is followed by remote and distributed work over a period of a few months, focussing on the bulk of the book. The Sprint Book methodology has already been used in the 'Wireless Networking in the Developing World' and 'Bandwidth Optimization and Management' books. Both of these are freely available under a Creative Commons License. (author)

    ABSTRACT OBJECTIVE To validate a Spanish version of the Test of Gross Motor Development (TGMD-2) for the Chilean population. METHODS Descriptive, transversal, non-experimental validity and reliability study. Four translators, three experts and 92 Chilean children, from five to 10 years, students from a primary school in Santiago, Chile, have participated. The Committee of Experts has carried out translation, back-translation and revision processes to determine the translinguistic equivalence and content validity of the test, using the content validity index in 2013. In addition, a pilot implementation was achieved to determine test reliability in Spanish, by using the intraclass correlation coefficient and Bland-Altman method. We evaluated whether the results presented significant differences by replacing the bat with a racket, using T-test. RESULTS We obtained a content validity index higher than 0.80 for language clarity and relevance of the TGMD-2 for children. There were significant differences in the object control subtest when comparing the results with bat and racket. The intraclass correlation coefficient for reliability inter-rater, intra-rater and test-retest reliability was greater than 0.80 in all cases. CONCLUSIONS The TGMD-2 has appropriate content validity to be applied in the Chilean population. The reliability of this test is within the appropriate parameters and its use could be recommended in this population after the establishment of normative data, setting a further precedent for the validation in other Latin American countries.

  3. Development of advanced version of ACTDOR software for determination of radioactivity content of solid radioactive waste

    International Nuclear Information System (INIS)

    It is a mandatory requirement of regulatory authority to know the activity content of radioactive solid waste disposed to the environment, which include assorted solid wastes and spent resins used in ion-exchange columns of process systems. This involves assessment of radioactivity content and the specification of radionuclides in the waste package before it is disposed in Near Surface Disposal Facility (NSDF). In house methods were developed at different nuclear power stations in the country to estimate the activity of the radioactive waste being generated and disposed. ACTDOR software was implemented and used at some nuclear power stations. To bring uniformity in the method of activity estimation, it was recommended to use ACTDOR at all the nuclear power stations. A Graphical User Interface (GUI) based user friendly version of ACTDOR software with additional features has been developed recently. This paper presents the development and the various features of the advanced ACTDOR software. ACTDOR is a software developed to quantify the radioactivity of solid waste in cylindrical geometry by measuring its external gamma radiation. It works on gamma shielding principles. ACTDOR software is developed in FORTRAN and the software is functioning in TEXT USER INTERFACE MODE. The advanced version of ACTDOR works in GUI MODE and has been developed with Visual Basic as Front End and Microsoft Access as Back End

    2014-01-01

    The present study presents prediction models for determining the N content in citrus leaves by using hyperspectral imaging technology combined with several chemometrics methods. The steps followed in this study are: hyperspectral image scanning, extracting average spectra curves, pretreatment of raw spectra data, extracting characteristic wavelengths with successive projection algorithm and developing prediction models for determining N content in citrus leaves. The authors obtained three optimal pretreatment methods through comparing eleven different pretreatment methods including Savitzky-Golay (SG) smoothing, standard normal variate (SNV), multiplicative scatter correction (MSC), first derivative (1-Der) and so on. These selected pretreatment methods are SG smoothing, detrending and SG smoothing-detrending. Based on these three pretreatment methods, the authros first extracted the characteristic wavelengths respectively with successive projection algorithm, and then used the spectral reflectance of the extracted characteristic wavelengths as input variables of partial least squares regression (PLS), multiple linear regression (MLR) and back propagation neural network (BPNN) modeling. Hence, the authors developed three prediction models with each pretreatment method, and obtained nine models in total. Among all the nine prediction models, the two models based on the methods of SG smoothing-detrending-SPA-BPNN (R(p): 0.8513, RMSEP: 0.1881) and detrending-SPABPNN (R(p): 0.8609, RMSEP: 0.1595) were found to have achieved the best prediction results. The final results show that using hyperspectra data to determine N content in citrus leaves is feasible. This would provide a theoretical basis for real-time and accurate monitoring of N content in citrus leaves as well as rational N fertilizer application during the plant's growth. PMID:24783563

    Buoni, Michael H.

    This study investigates the degree to which the Delaware Science Coalition tenth grade biology kit curriculum supports the development of teachers' pedagogical content knowledge. A research-based construct for PCK was developed to serve as the foundation for how PCK was defined in this study. An analysis tool was created using the Davis and Krajcik (2005) nine heuristics of effectiveness of curriculum materials to develop science teachers' PCK. The tool was created to analyze the relative effectiveness of curriculum materials in supporting and developing teachers' PCK. The Delaware Science Coalition tenth grade biology kit curriculum was analyzed against this heuristic tool, and was found to be inconsistent in developing teachers' PCK. In addition, this study addressed teachers' conceptions of PCK, and their perceptions of professional development, through a survey and through subsequent interviews. The results from the survey and interviews showed that teachers consistently adapt the curriculum to fit their needs, and also had different feelings about the professional development they experienced with the state, and at their home school. A new model for professional development was created using the research-based construct of PCK, the heuristic tool to develop teachers' PCK, and teachers' experiences with curriculum and professional development.

  10. How international oil and gas companies respond to local content policies in petroleum-producing developing countries: A narrative enquiry

    International Nuclear Information System (INIS)

    This paper uses narrative analysis to critically examine the business practices used by five international oil and gas companies (IOCs) (Chevron, ExxonMobil, Shell, BP and Total) to respond to local content policies in petroleum-producing developing countries (Nigeria, Angola, Venezuela, Kazakhstan, Brazil, Indonesia, Yemen and Indonesia) during the period 2000–2012. The business practices include the formulation of local content strategies that are implemented through programmes and initiatives aimed at developing and using host country suppliers and workforce. Such practices and the narratives used to communicate them implicitly reflect the context in which the effectiveness of local content policies on economic development can be assessed. By comparing and contrasting the narratives across the five IOCs in relation to the wider literature, four emergent narrative strategies justifying the business practices of IOCs are identified and discussed. They include: (1) direct engagement to renegotiate local content requirements with governments, (2) legal compliance framework, (3) the business case for local content strategies, and (4) corporate social responsibility (CSR) initiatives. The conclusion considers the policy implications of these findings for local content development in petroleum-producing developing countries. - Highlights: • Local content policies define the local context that shape IOCs’ business practices. • Provides a narrative analysis of the business practices of IOCs in developing countries. • IOCs use four narrative strategies to relate their business practices to local content policies. • The business practices of IOCs can determine the effectiveness of local content policies

    Full Text Available Karon F Cook1, Seung W Choi2, Kurt L Johnson1, Dagmar Amtmann11Department of Rehabilitation Medicine, University of Washington, Seattle, WA; 2Northwestern University Feinberg School of Medicine, Chicago, IL, USAAbstract: There are clinical and research settings in which concerns about respondent burden make the use of longer self-report measures impractical. Though computer adaptive testing provides an efficient strategy for measuring patient reported outcomes, the requirement of a computer interface makes it impractical for some settings. This study evaluated how well brief short forms, constructed from a longer measure of patient reported fatigue, reproduced scores on the full measure. When the items of an item bank are calibrated using an item response theory model, it is assumed that the items are fungible units. Theoretically, there should be no advantage to balancing the content coverage of the items. We compared short forms developed using a random item selection process to short forms developed with consideration of the items relation to subdomains of fatigue (ie, physical and cognitive fatigue. Scores on short forms developed using content balancing more successfully predicted full item bank scores than did scores on short forms developed by random selection of items.Keywords: psychometrics, outcomes, quality of life, measurement, fatigue

    Earth science data collections range from individual researchers' private collections to large-scale data warehouses, from computer-generated data to field or lab based observations. These collections require stewardship. Fundamentally, stewardship ensures long term preservation and the provision of access to the user community. In particular, stewardship includes capturing appropriate metadata and documentation--and thus the context of the data's creation and any changes they underwent over time --to enable data reuse. But scientists and science data managers must translate these ideas into practice. How does one balance the needs of current and (projected) future stakeholders? In 2011, the Data Stewardship Committee (DSC) of the Federation of Earth Science Information Partners (ESIP) began developing the Provenance and Context Content Standard (PCCS). As an emerging standard, PCCS provides a framework for 'what' must be captured or preserved as opposed to describing only 'how' it should be done. Originally based on the experiences of NASA and NOAA researchers within ESIP, the standard currently provides data managers with content items aligned to eight key categories. While the categories and content items are based on data life cycles of remote sensing missions, they can be generalized to cover a broader set of activities, for example, preservation of physical objects. These categories will include the information needed to ensure the long-term understandability and usability of earth science data products. In addition to the PCCS, the DSC is developing a series of use cases based on the perspectives of the data archiver, data user, and the data consumer that will connect theory and practice. These cases will act as specifications for developing PCCS-based systems. They will also provide for examination of the categories and content items covered in the PCCS to determine if any additions are needed to cover the various use cases, and also provide rationale and

    Full Text Available Flavonoids, the pharmaco-active compounds studied in this work, in general, are located in the shoots as natural pigments that protect the plants from damage by oxidizing agents. The experiment was conducted in the greenhouse of the Fitotecnia Department, Federal University of Viçosa, Minas Gerais Staty. The experimental design was completely randomized with five treatments and five replications. The treatments were the time of harvest: zero, three, six, nine, and twelve days after anthesis (DAA. The height of the plant (mm, stem diameter (mm, number of leaves and total flavonoid content (%, w w-1 were determined. We developed growth curves for calendula with growth behavior assessed through time for height, stem diameter and number of leaves. The time of the harvest season positively influenced the total flavonoid contents and the average productivity of flowers, and the highest content of flavonoids was found three DAA. The average productivity of the flowers and the accumulation of flavonoids were heterogeneous among harvest times (0, 3, 6, 9 and 12 days after anthesis. The highest yield of flavonoids was obtained three days after anthesis; therefore, a harvest of the inflorescences is recommended every three days.

    Full Text Available Few studies in Brazil have addressed the need for micronutrients of physic nut focusing on physiological responses, especially in terms of photosynthesis. The objective of this study was to evaluate the effects of omission of boron (B, copper (Cu, iron (Fe, manganese (Mn and zinc (Zn on Jatropha curcas L.. The experimental design was a randomized block with four replications. The treatments were complete solution (control and solution without B, Cu, Fe, Mn, and Zn. We evaluated the chlorophyll content (SPAD units, photosynthetic rate, dry matter production and accumulation of micronutrients in plants, resulting from different treatments. The first signs of deficiency were observed for Fe and B, followed by Mn and Zn, while no symptoms were observed for Cu deficiency. The micronutrient omission reduced the dry matter yield, chlorophyll content and photosynthetic rate of the plants differently for each omitted nutrient. It was, however, the omission of Fe that most affected the development of this species in all parameters evaluated. The treatments negatively affected the chlorophyll content, evaluated in SPAD units, and the photosynthetic rate, except for the omission of B. However this result was probably due to the concentration effect, since there was a significant reduction in the dry matter production of B-deficient plants.

    Full Text Available Textbooks are widely used as a teaching tool, and are considered very important in severaleducational environments, from elementary to tertiary education levels. Since the firsttextbook arose in the seventeenth century, printed books are the most popular format oftextbooks published. New technologies developed over years such as paper, ink andprinting hardware. These have made it possible to present printed books in even moreattractive formats. Moreover, digital technologies allowed textbooks to providecomplementary content, such as software, audio and video. Aiming to understand hownew technologies has impacted both textbook presentation and content, we run anexternal representations (ER content analysis in a textbook chapter and on aneducational software (eBook, both about muscle contraction. The three editions ofBioquímica Básica textbook (1990, 1999 and 2007, written by Anita Marzzoco andBayardo B. Torres and the four versions of Contração Muscular software developed byEduardo Galembeck et al. were analyzed. The obtained results showed that the textbookhad changes in relation to typography (paper size, kind of paper and colors of printing,and to ERs presented (use of electronic micrograph and 3D models in the 3rd edition andthe exclusion of some images and graphs previously used. Regarding the ContraçãoMuscular software, there were several changes in relation to the visual aspect, such asimages and icons, and also code updates to make the software compatible with newtechnologies developed since the first version was released. Although technology hasdriven some updates in both cases, this happened in different aspects includingpossibilities to create a modern layout and cheaper printer services, in the case of thetextbook, and graphic design and software usability, in the case of the eBook.

    The effect of water content in the electrolyte solution during annealing process in the synthesis and modification of titania nanotube arrays (TNTAs) by anodic oxidation process has been investigated. Variations in annealing technique that leading to some specific properties of the TNTAs produced have been examined. Doped-TNTAs were obtained by the in-situ anodic oxidation method in glycerol containing fluoride solution followed by annealing to induce crystallization. FESEM and SEM results indicated that TNTAs with inner diameters of 49–80 nm, wall thicknesses from 28 to 42 nm and lengths from 1407 to 1570 nm were synthesized. At water content of 25 v% in the electrolyte solution, self-organized with vertical, ordered of TNTAs with relatively uniform diameter was observed. Suitable morphology of TNTAs such as well developed tubes, vertically oriented, highly ordered, long with optimal diameter and wall thickness of TNTAs could suppress recombination of electrons–holes and, therefore, increase photoelectrochemical properties. Annealing with H{sub 2}/Ar is found to be efficient for introducing dopant C and N into the lattice of TNTAs to form Ti–O–C and N–Ti–O (FTIR analysis). Therefore, the reducing band gap can be obtained (UV–Vis DRS analysis). Annealing under H{sub 2}/Ar of as-synt TNTAs with water content of 25 v% in the electrolyte solution produced anatase phase (XRD analysis) and showed optimal condition in producing the highest photocurrent density. - Highlights: • Water content of 25 v%, annealing with 20% H{sub 2} produced highest photocurrent of TNTAs. • Vertically oriented, long with optimal wall thickness of TNTAs increase photocurrent. • Annealing with H{sub 2}/Ar plays an effective role in reducing the band gap.

    2012-08-01

    In many innovative science content professional development (PD) courses for teachers, science concepts are situated within pedagogical contexts, or in other words, science content is incorporated within contexts relevant to teaching and student learning. Pedagogical contexts are often used because they are believed to be engaging for teachers and to support content transfer to the classroom. However, few studies have investigated how pedagogical contexts serve to impact teacher engagement and science content learning. This qualitative case study examined K-8 in-service teachers' interactions with pedagogical contexts in a chemistry PD course. Findings indicate that teachers': (1) contribution of teaching experiences helped create a collegial learning environment, (2) sharing of concerns from classroom teaching directed content discussion and learning objectives, and (3) reflection on teacher and learner roles in the PD classroom led to persistence in chemistry-content learning. Implications for PD instructor use of pedagogical contexts in science content based PD are discussed.

    2012-05-01

    In view of the lack of instruments for measuring biology teachers' pedagogical content knowledge (PCK), this article reports on a study about the development of PCK items for measuring teachers' knowledge of pupils' errors and ways for dealing with them. This study investigated 9th and 10th grade German pupils' (n = 461) drawings in an achievement test about the knee-jerk in biology, which were analysed by using the inductive qualitative analysis of their content. The empirical data were used for the development of the items in the PCK test. The validation of the items was determined with think-aloud interviews of German secondary school teachers (n = 5). If the item was determined, the reliability was tested by the results of German secondary school biology teachers (n = 65) who took the PCK test. The results indicated that these items are satisfactorily reliable (Cronbach's alpha values ranged from 0.60 to 0.65). We suggest a larger sample size and American biology teachers be used in our further studies. The findings of this study about teachers' professional knowledge from the PCK test could provide new information about the influence of teachers' knowledge on their pupils' understanding of biology and their possible errors in learning biology.

  4. Secondary Science Teachers' Development of Pedagogical Content Knowledge as Result of Integrating Nanoscience Content in Their Curriculum

    2013-06-01

    Nanoscale science is a rapidly-developing, multidisciplinary field of science and research that combines engineering, chemistry, physics, biology, and information technology pushes and the boundary between the science and the technology required to conduct it. Nanoscale science involves investigating and working with matter on the scale of 1-100 microns and has broad societal implications for new technologies. It is estimated that the worldwide workforce necessary to support the field of nanoscale science and nanotechnology will be close to 2 million by 2015 (National Nanotechnology Initiative, 2005). With such rapid developments in nanoscale science and technology, it is becoming more incumbent upon K-12 science teachers to provide the learning experiences necessary for students to understand the principles that govern behavior at the nanoscale and develop the skills needed to apply these concepts to improve everyday life. While onlya limited amount of nanoscale curricular materials are available for K-12 and undergraduate education many important unanswered questions exist, including: How do science teachers learn to teach nanoscale science?

    2014-07-01

    It is a common view that developing teachers' competence to restructure or reframe their knowledge and beliefs is inevitably a complex challenge. This paper reports on a research project with the aim to develop science teachers' pedagogical content knowledge (PCK) through their participation in a learning study. A learning study is a collegial process in which teachers work together with a researcher to explore their own teaching activities in order to identify what is critical for their students' learning. During one semester, three secondary science teachers worked in a learning study together with a researcher in a cyclical process in order to create prerequisites and further identify conditions for students' learning. During the learning study, data were collected from video-recorded lessons and stimulated recall sessions in which the teachers and the researcher reflected on the lessons to analyze their development of PCK, their students' learning and the impact of that knowledge on their own teaching. The results provide an insight into how the teachers developed their self-understanding in which they questioned their own epistemological beliefs, aims and objectives of teaching and taken-for-granted assumptions about science teaching and learning. As such, the study provides an understanding of teacher professional learning through a careful investigation of how teachers' PCK is enhanced through their participation in the learning study, and further, how students' learning might be developed as a consequence.

  8. Serum-mucoid fraction content in development of skin acute radiation necrosis in rats

    International Nuclear Information System (INIS)

    Serum-mucoid fraction composition (in polyacrilamide gel) in rats during the different stages of local acute radiation injury of skin (6000 rad irradiation) has been studied. For this injury type during all the periods no appearance of new, unusual for the norm, fractions of serum-mucoids is noted. 2 stages of changes in serum-mucoid fractions have been revealed: the simultaneous increase in the content of all the serum-mucoid components is observed during acute period (bullous dermatitis); during a necrotic period of development of acute skin radiation injury the level of the third fraction increases, the number of the first fraction decreases, the content of the second and forth fractions changes slightly. The level of total serum-mucoids is predominantly determined by the changes of the third fraction, growth of which during the ulcer-necrotic period depends clearly on an injury degree. The determination of the third fraction containing, likely, low molecular haptoglobin in these cases can be of prognostic and diagnostic values

    2015-11-01

    Research suggests discipline-specific, educative mentoring can help preservice teachers develop more sophisticated pedagogical content knowledge (PCK). However, there are few studies examining the nature of mentors' practice and how mentors influence preservice teacher's (PST) PCK. The purpose of this case study was to describe the strategies used by a secondary biology mentor teacher to support the development of a PST's PCK. The primary data sources were the transcripts of audio-recorded, daily meetings between the mentor and the PST during two curriculum units: DNA/Protein Synthesis and Evolution. The mentor influenced the PST's teaching orientation by repeatedly comparing teacher- and student-centered approaches, asking him to consider how students learn, and asking him to self-assess whether his instruction aligned with his teaching beliefs. The mentor helped the PST develop topic-specific knowledge of instructional strategies by sharing strategies she used previously, modeling critical reflection, and inviting him to critically reflect on his own instructional strategies. Topic-specific knowledge of students' understanding of science was developed by discussing common student misconceptions revealed in students' conversations and by sharing the results of test-item analysis from previous unit tests. The mentor helped develop the PST's topic-specific knowledge of assessment by helping him critically analyze and revise previous examinations to better align with the current curriculum units. Topic-specific knowledge of curricula was developed by jointly grappling with decisions about concept sequencing within units. The study includes implications for research, science teacher education, and professional development for mentors.

    Full Text Available In this article, we discuss the negotiation of the situated common ground in classroom conversations. Decision making on socioscientific issues (SSI includes norms of diverse funds of knowledge and interests. Arguments and justification may include warrants that cannot necessarily be weighed on the same scale. We discuss Roberts’ Visions 1 and 2 of scientific literacy as framing the common ground of classroom discussions. Two teacher–student dialogue sequences with 11th grade students from the Norwegian research project ElevForsk exemplify the negotiation of the situated common ground and the students’ deliberations. Our analysis examines what goes on in the thematic content, as well as at the interpersonal level of language use. Further, we suggest that different framings may complement each other and provide a space for the students’ emerging scientific conceptual development as well as for deliberation as a form of emerging procedural knowing.

    2016-08-01

    Recent research, both internationally and in Norway, has clearly expressed concerns about missing connections between subject-matter knowledge, pedagogical competence and real-life practice in schools. This study addresses this problem within the domain of field practice in teacher education, studying pre-service teachers' planning of a Physics lesson. Two means of intervention were introduced. The first was lesson study, which is a method for planning, carrying out and reflecting on a research lesson in detail with a learner and content-centered focus. This was used in combination with a second means, content representations, which is a systematic tool that connects overall teaching aims with pedagogical prompts. Changes in teaching were assessed through the construct of pedagogical content knowledge (PCK). A deductive coding analysis was carried out for this purpose. Transcripts of pre-service teachers' planning of a Physics lesson were coded into four main PCK categories, which were thereafter divided into 16 PCK sub-categories. The results showed that the intervention affected the pre-service teachers' potential to start developing PCK. First, they focused much more on categories concerning the learners. Second, they focused far more uniformly in all of the four main categories comprising PCK. Consequently, these differences could affect their potential to start developing PCK.

    2011-08-01

    Temperature plays an important role in effective management of the alfalfa leafcutting bee [Megachile rotundata (F.); Megachilidae], the major commercial pollinator of seed alfalfa [Medicago sativa (L.); Fabaceae] in North America. To improve our understanding of threshold and optimum rearing temperatures of M. rotundata, we examined the effect of temperature on postwintering development by using a greater number of temperature treatments than applied in previous studies (19 versus eight or fewer) and analytical tools formulated to model nonlinear relationships between temperature and insect development rates. We also tested the hypothesis that rearing temperature influences adult body lipid content at emergence, which could affect adult survival, establishment and performance as a pollinator, and reproductive success. We found that the Lactin-2 and Briere-2 models provided the best fits to data and gave reasonable estimates of lower (16-18°C) and upper (36-39°C) developmental thresholds and optimum (33-34°C) rearing temperatures for maximizing development rate. Bees successfully emerged over a broad range of temperatures (22-35°C), but variation in development rate among individuals reared at the same temperature was lowest at 31-33°C. The optimum rearing temperature to maximize the proportion of body lipids in adults was 27-29°C. Our results are discussed in relation to previous findings and speak to the difficulties in designing practical rearing guidelines that simultaneously maximize development rate, survival, and adult condition, while synchronizing adult emergence with alfalfa bloom.

    Smith, Erica L.

    This study was situated in a NSF-funded multi-year teacher professional development project, STIS, between the university and a school district in the North Eastern United States. The STIS project affords an opportunity to understand the processes and conditions in which science teachers develop interdisciplinary science inquiry knowledge and how that is translated into their pedagogical content knowledge (PCK). As part of that study and within the framework of PCK in science, this study explored (1) the extent to which the involvement of in-service science teachers in authentic research experiences impacts their PCK of interdisciplinary science inquiry, and (2) the factors that contribute to or constrain the development of interdisciplinary science inquiry PCK. This research study utilized a mixed method, explanatory research design. Cross-case analysis of 10 teachers and the development of 3 case studies were done to examine the development of in-service science teachers PCK over the course of the first 3 years of the STIS project. Results showed that teachers participating in the STIS project demonstrated various levels of change in regards to their PCK, understanding of ISI, and implementation of ISI in classroom practices. The core features of STIS identified as impacting this change included (1) the summer research connection, (2) collaboration with STEM students, (3) an active learning environment, and (4) duration. The core features and the major contextual factors that were identified were utilized to revise the STIS' conceptual framework and create a theory of action. The findings of this study have implications for planning and conducting effective in-service for science educators.

  17. Improving technological pedagogical content knowledge development among pre-service science teachers

    Science.gov (United States)

    Habowski, Thomas A.

    Many teacher education programs provide pre-service teachers with a limited field experience during the professional block semester prior to student teaching. These programs require few hours in the classroom, mainly composed of observations. Many teacher education programs contain a technology-integration methods course that is not subject-specific and mainly focuses on the use of various technologies, in the absence of content and pedagogy. The purpose of this EPP was to examine a Professional Development School (PDS) Program with respect to technology integration among pre-service science teachers. This examination set out to measure differences in pre-service teachers' Technological Pedagogical Content Knowledge (TPACK) before and after the first-semester internship in the program, and utilized various data collection instruments in the process. The primary instrument used was a survey which provided quantitative data for measuring changes in TPACK among the interns throughout the first-semester internship. A set of open-ended questions on the survey provided descriptive details concerning models of TPACK observed and co-taught by the interns. Additionally, a focus group and a PDS conference provided descriptive data concerning observed models of technology, the impact of a subject-specific technology integration course, comparisons between the PDS and traditional teacher education programs, and insight into the comfort and success levels with using technology in the science classroom. The survey responses, the focus group responses, and the PDS conference data all suggested that the increased time requirement, in conjunction with the required technology integration course, and the mentorship provided by a co-teaching model led to exposure to valuable models of technology, an increase in self-assessed TPACK, and a feeling of increased confidence as reported by the interns during the first-semester internship of the PDS Program.

  20. Employing WebGL to develop interactive stereoscopic 3D content for use in biomedical visualization

    Science.gov (United States)

    Johnston, Semay; Renambot, Luc; Sauter, Daniel

    2013-03-01

    Web Graphics Library (WebGL), the forthcoming web standard for rendering native 3D graphics in a browser, represents an important addition to the biomedical visualization toolset. It is projected to become a mainstream method of delivering 3D online content due to shrinking support for third-party plug-ins. Additionally, it provides a virtual reality (VR) experience to web users accommodated by the growing availability of stereoscopic displays (3D TV, desktop, and mobile). WebGL's value in biomedical visualization has been demonstrated by applications for interactive anatomical models, chemical and molecular visualization, and web-based volume rendering. However, a lack of instructional literature specific to the field prevents many from utilizing this technology. This project defines a WebGL design methodology for a target audience of biomedical artists with a basic understanding of web languages and 3D graphics. The methodology was informed by the development of an interactive web application depicting the anatomy and various pathologies of the human eye. The application supports several modes of stereoscopic displays for a better understanding of 3D anatomical structures.

    The purpose of this case study is to delve into the complexities of the early development of preservice chemistry teachers' science teaching orientations, knowledge of learners, knowledge of instructional strategies, and knowledge of assessment during a two-semester intervention designed to enhance their pedagogical content knowledge (PCK) for teaching nature of science (NOS). Thirty preservice chemistry teachers enrolled in a Research in Science Education course participated in the study. Qualitative data sources included responses to an open-ended instrument, interviews, observations, and artifacts such as lesson plans and reflection papers. Through the in-depth analysis of explicit PCK and constant comparative method of analysis, we identified the influence of the intervention on participants' PCK for NOS. Analysis of data revealed four major themes related to the nature of preservice chemistry teachers' NOS teaching practices and their PCK for NOS: (1) prerequisite knowledge and beliefs are necessary to teach NOS, (2) there is a developmental progression of PCK for NOS from knowledge to application level, (3) teachers need some comfort in their NOS understanding to teach NOS, and (4) the higher integration of PCK components leads to successful NOS teaching practices. Implications for science teacher education and research are discussed.

    We searched for the easy and simple method to measure the novel indicators which reflect not only AAC, but also (RS) based on pasting properties using RVA. Novel indexes such as SB/Con and Max/Fin (Maximum viscosity/Minimum viscosity) ratios had a very high correlation with proportion of intermediate and long chains of amylopectin; Fb1+2+3 (DP ≧ 13). In Japonica polished rice, estimation formulae for AAC and RS content were developed using novel indexes based on pasting properties by RVA, and these equations showed determination coefficients of 0.89 and 0.80 for calibration and 0.71 and 0.75 for validation test. We developed the estimation formulae for AAC and RS content for Japonica starch samples. These equations showed determination coefficients of 0.86 and 1.00 for calibration and 0.76 and 0.83 for validation test, which showed that these equations can be applied to the unknown rice samples.

    Full Text Available Kuntorini EM, Nugroho LH (2010 Structural development and bioactive content of red bulb plant (Eleutherine americana; a traditional medicines for local Kalimantan people. Biodiversitas 11 (2: 102-106. Red bulb plant or “bawang dayak” (Eleutherine americana Merr. is commonly used as a traditional medicine especially for anti breast cancer of Kalimantan people, because it contains bioactive naphtoquinone-derivatives. Naphtoquinones is usually used as antimicrobial, antifungal, antiviral and antiparasitic agents. This study was aimed to complete the investigation of Red bulb plant as a traditional medicine from anatomical and phytochemical point of view, especially the anatomical structure of bulb and leaf of red bulb plants during their development and their naphtoquinone derivative contents. The anatomical structures of bulb and leaf were analyzed by paraffin embedding method and naphtoquinone derivative contents were analyzed using HPLC. During plant development, the diameter and the length of bulbs as well as the thickness of mesophyll and epidermis layers of the leaves increased significantly. The size of vascular bundles increased and so did phloem and xylem components. The content of bioactive compounds in bulbs increased significantly as the size of parenchymal cells increased. There was no significant difference in the content of bioactive compounds of leaves during development, despite the rise in the thickness of mesophyll and the constituting cells as the location of synthesis.

    Full Text Available The effects of pollen protein content on the colony development of Bombus terrestris were investigated by feeding queens and queenright colonies with four different pollen diets. We used three kinds of commercially available pure pollen (Cistus spp. 11.9%, Papaver somniferum 21.4%, and Sinapis arvensis 21.8% crude protein. We also used a mixture which was made up of equal weights of these pure pollens (18.4 % crude protein. All queens and colonies were fed with sugar syrup and pollen diets ad libitum (28 ± 1 ℃, 65 ± 5% RH. Until there were 50 workers reached, colonies fed with the Cistus pollen diet (167.4 ± 28.9 g consumed significantly more pollen than colonies fed with the Papaver pollen diet (140.7 ± 15.7 g, the mixed pollen diet (136.2 ± 20.1 g or colonies fed with the Sinapis pollen diet (132.4 ± 22.6 g. The date when there were 50 workers reached was approximately one week later in the colonies fed with the Cistus, and colonies fed with the Papaver diet than in the colonies fed with the Sinapis diet, and for colonies fed with the mixed pollen diets. Considering 8 tested criteria, the best performances were observed using the Sinapis, and using the mixed pollen diets. The lowest performances were observed using the Cistus pollen diet. Results showed that pollen sources play an important role in commercial bumblebee rearing. Results also showed that the polyfloral pollen diets are more suitable for mass rearing of bumblebees than the unifloral pollen diets.

    Alternatives for realizing a packet-based network switch for use on a frequency division multiple access/time division multiplexed (FDMA/TDM) geostationary communication satellite were investigated. Each of the eight downlink beams supports eight directed dwells. The design needed to accommodate multicast packets with very low probability of loss due to contention. Three switch architectures were designed and analyzed. An output-queued, shared bus system yielded a functionally simple system, utilizing a first-in, first-out (FIFO) memory per downlink dwell, but at the expense of a large total memory requirement. A shared memory architecture offered the most efficiency in memory requirements, requiring about half the memory of the shared bus design. The processing requirement for the shared-memory system adds system complexity that may offset the benefits of the smaller memory. An alternative design using a shared memory buffer per downlink beam decreases circuit complexity through a distributed design, and requires at most 1000 packets of memory more than the completely shared memory design. Modifications to the basic packet switch designs were proposed to accommodate circuit-switched traffic, which must be served on a periodic basis with minimal delay. Methods for dynamically controlling the downlink dwell lengths were developed and analyzed. These methods adapt quickly to changing traffic demands, and do not add significant complexity or cost to the satellite and ground station designs. Methods for reducing the memory requirement by not requiring the satellite to store full packets were also proposed and analyzed. In addition, optimal packet and dwell lengths were computed as functions of memory size for the three switch architectures.

    Full Text Available Abstract Background Several health determinants are related to local conditions and prerequisites at community level. For this reason, strengthening community action has been one of five strategies implemented in health promotion since the end of the 1980s. Such action includes setting priorities, making decisions, planning strategies, and implementing them to achieve better health. The aim of this paper is to obtain a deeper understanding of content, organization and processes in the development of local health promotion. Methods A qualitative multiple case study of four Swedish municipalities. The cases were analyzed in accordance with the principles of cross-case study analysis, and a content analysis of documents and interviews was conducted in two steps. First, a manifest content analysis was performed to identify present and former actors and measures. Thereafter, a latent content analysis was performed to investigate structures and processes in local contexts. Results The results of the inductive content analysis showed development of local health promotion in three phases: initiation, action, and achievement. Strengthening factors were local actors, health statistics and events. Hindering factors were lack of resources and vague objectives. External factors, e.g. national policies, were not perceived as prominent influencing factors. Media reports were regarded as having had an influence, but only to some extent. The content of local health promotion has developed from ad-hoc lifestyle and behaviour-related actions into structural, intersectoral actions related to determinants of health. Conclusions The municipalities have organized and developed their health promotion targets, actions and priorities on the basis of local needs and prerequisites. The three phases in the identified health promotion processes were experienced and documented as being subject to greater influence from internal rather than external strengthening and hindering

    Full Text Available Problem statement: Teleconsultation services had been introduced in Malaysia for almost 10 years yet it has not been optimally adopted even though it was found that teleconsultation in Malaysia is cost saving, efficient in allocating resources, enhances diagnostic options and better health outcomes. At present, the underutilized service is due to its failure to satisfy the user’s demands on various aspects. Since Teleconsultation in BSE is at proposal stage, there is strong need for user’s involvement in suggesting its contents to harvest end-user acceptance. This study describes the development process of the Web-based Breast Self-Examination (BSE Teleconsultation System, emphasizing the role of public users in identifying the contents of the system and its functionality using our proposed Modified UCC (MUCC approach. To help understanding the process we first presents the key concepts related to original User-Created Content (UCC approach; next we describes in details the data gathering process which applied qualitative method; we then describes the web-based application for BSE Teleconsultation, as well as, the development process illustrating the transition from the MUCC to the system development; and finally we discusses the importance of the user’s input in the system development from our experience. Approach: A semi-structured one-to-one interviews with 15 public users was carried out in October 2008 in one of the public university in Malaysia to capture the content of the system based on our proposed MUCC approach. Results: By using our MUCC approach, the content of the proposed system has been identified and the BSE Teleconsultation system has been successfully developed. Conclusion/Recommendations: MUCC approach proposed and used in this study has provides insights on user’s role in e-health system development.

    Full Text Available Fried bread sticks (FBS are one of the most widely consumed deep fried food products in China. Understanding the fat and moisture content in FBS will help consumers make healthy food choices as well as assist food processors to provide FBS with desirable quality. Rapid Fourier transform near-infrared methods (FT-NIR were developed for determining fat and moisture content in FBS collected from 123 different vendors in Shanghai, China. FBS samples with minimum sample preparation (either finely or coarsely ground were used for NIR analyses. Spectra of FBS were treated with different mathematic pretreatments before being used to build models between the spectral information and fat (7.71%–30.89% or moisture (17.39%–32.65% content in FBS. Finely ground samples may lead to slightly more robust PLS models, but the particle sizes of ground FBS samples did not seriously affect the predictability of the models with appropriate mathematical treatments. The fat and moisture content in FBS predicted by FT-NIR methods had very good correlation with their values determined via traditional methods (fat, R2=0.965; moisture, R2=0.983, which clearly indicated that FT-NIR methods could be used as an effective tool for rapid determination of fat and moisture content in FBS.

    2015-07-01

    Previous research has shown the use of electronic video games as an effective method for increasing content knowledge about the risks of drugs and alcohol use for adolescents. Although best practice suggests that theory, health communication strategies, and game appeal are important characteristics for developing games, no instruments are currently available to examine the quality and content of tobacco prevention and cessation electronic games. This study presents the systematic development of a coding instrument to measure the quality, use of theory, and health communication strategies of tobacco cessation and prevention electronic games. Using previous research and expert review, a content analysis coding instrument measuring 67 characteristics was developed with three overarching categories: type and quality of games, theory and approach, and type and format of messages. Two trained coders applied the instrument to 88 games on four platforms (personal computer, Nintendo DS, iPhone, and Android phone) to field test the instrument. Cohen's kappa for each item ranged from 0.66 to 1.00, with an average kappa value of 0.97. Future research can adapt this coding instrument to games addressing other health issues. In addition, the instrument questions can serve as a useful guide for evidence-based game development. PMID:26167842

  18. Development of new PIT process using high Ga content compound in V3Ga superconducting wire

    International Nuclear Information System (INIS)

    Vanadium-gallium (V3Ga) superconducting wire is an 'old superconducting material', and was one of the original materials famed for the 'Cu additive effect' that was extended to the 'Bronze route process. The 'Cu additive effect' in A15 phase compounds promotes A15 phase formation via diffusion reaction. The V3Ga compound has interesting properties for an advanced magnetic confinement fusion reactor beyond ITER. The decay time of induced radio activity for V3Ga is within 1 month and is much shorter than that of Nb-based superconductors such as Nb-Ti, Nb3Sn and Nb3Al. We thought that V3Ga wire was one of the candidate materials for 'Low activation superconducting wires' to operate under a neutron irradiation environment such as in a fusion reactor. However, the Jc and Hc2 properties of V3Ga wire are insufficient to realize this feature in fusion application. In previous studies, V3Ga wire was mainly investigated in term of the 'Diffusion process' between Cu-Ga within a 20 at% Ga composition and V filament. For further Jc and Hc2 enhancements, we investigated the fabrication of V3Ga compound multi-filamentary wires using a high Ga content Cu-Ga compound applying the powder-in-tube process. Thicker V3Ga layers formed along the boundary between the Cu-Ga powder filaments and V matrix, and the volume fraction of V3Ga increased compared to previous diffusion processed samples. We also found that the new route PIT process using a high Ga content Cu-Ga compound is effective for improving the superconducting properties of the V3Ga compound wire. (author)

    One of the rate-limiting procedures in a developmental zebrafish screen is the morphological assessment of each larva. Most researchers opt for a time-consuming, structured visual assessment by trained human observer(s). The present studies were designed to develop a more objective, accurate and rapid method for screening zebrafish for dysmorphology. Instead of the very detailed human assessment, we have developed the computational malformation index, which combines the use of high-content imaging with a very brief human visual assessment. Each larva was quickly assessed by a human observer (basic visual assessment), killed, fixed and assessed for dysmorphology with the Zebratox V4 BioApplication using the Cellomics® ArrayScan® V(TI) high-content image analysis platform. The basic visual assessment adds in-life parameters, and the high-content analysis assesses each individual larva for various features (total area, width, spine length, head-tail length, length-width ratio, perimeter-area ratio). In developing the computational malformation index, a training set of hundreds of embryos treated with hundreds of chemicals were visually assessed using the basic or detailed method. In the second phase, we assessed both the stability of these high-content measurements and its performance using a test set of zebrafish treated with a dose range of two reference chemicals (trans-retinoic acid or cadmium). We found the measures were stable for at least 1 week and comparison of these automated measures to detailed visual inspection of the larvae showed excellent congruence. Our computational malformation index provides an objective manner for rapid phenotypic brightfield assessment of individual larva in a developmental zebrafish assay.

    Beetroot, a food rich in nitrate and antioxidants has gained attention because of its potential effect on improving cardiovascular health and exercise performance. This work had the purpose of developing a beetroot-based nutritional gel (BG) and estimating the in vitro bioaccessibility of the nitrate, total antioxidant capacity (TAC), total phenolic (TP) and potassium content, as compared to beetroot juice (BJ). Nitrate was assessed by a high-performance liquid chromatography system, TAC was assessed using the Trolox equivalent antioxidant capacity (TEAC) assay and TP was measured using the Folin-Ciocalteu method before and after an in vitro digestion. Significantly higher values of nitrate, TEAC, TP and potassium before and after digestion were observed in BG as compared to BJ. The results suggest a new nutritional strategy to give high contents of bioaccessible nutrients (nitrate, antioxidants and potassium) that are potentially relevant to improve cardiovascular health and exercise performance.

    International Nuclear Information System (INIS)

    The aim was to determine the effect of gamma irradiation of eggs of silk moth in B2 stage in doses of 1.00, 2.00 and 3.00 Gy on the changes of total nitrogen and protein content during different stages of Bombyx mori L. development. Highest levels of total nitrogen and protein were found in silk gland 14.032-14.355 mg%, followed by pupae - 7.448-8.092 and 46.550-48.906 mg%, moths after egg laying - 6.650-7.825 and 41.563-48.906 mg% and silkworm hemolymph - 6.920-6.980 and 43.250-43.625 mg%, respectively. The irradiation of eggs with 2.00 and 3,00 Gy gamma rays stimulated the increase of total nitrogen and protein content in silk gland by 6.66-7.3% compared to non-irradiated eggs of the same breed. 14 refs., 3 tabs.

    Lee Fung Ang

    Full Text Available An amperometric enzyme-electrode was introduced where glucose oxidase (GOD was immobilized on chitosan membrane via crosslinking, and then fastened on a platinum working electrode. The immobilized enzyme showed relatively high retention activity. The activity of the immobilized enzyme was influenced by its loading, being suppressed when more than 0.6 mg enzyme was used in the immobilization. The biosensor showing the highest response to glucose utilized 0.21 ml/cm2 thick chitosan membrane. The optimum experimental conditions for the biosensors in analysing glucose dissolved in 0.1 M phosphate buffer (pH 6.0 were found to be 35°C and 0.6 V applied potential. The introduced biosensor reached a steady-state current at 60 s. The apparent Michaelis-Menten constant ([Formula: see text] of the biosensor was 14.2350 mM, and its detection limit was 0.05 mM at s/n > 3, determined experimentally. The RSD of repeatability and reproducibility of the biosensor were 2.30% and 3.70%, respectively. The biosensor was showed good stability; it retained ~36% of initial activity after two months of investigation. The performance of the biosensors was evaluated by determining the glucose content in fruit homogenates. Their accuracy was compared to that of a commercial glucose assay kit. There was no significance different between two methods, indicating the introduced biosensor is reliable.

  8. Development of assessment methods for transport and storage containers with higher content of metallic recycling material

    International Nuclear Information System (INIS)

    The mechanical behaviour of transport and storage containers made of ductile cast iron melted with a higher content of recycled metal from decommissioning and dismantling of nuclear installations is investigated. Using drop tests with cubic container-like models, the influence of different real targets on the stresses in the cask body and the fracture behaviour is examined. A foundation for a test stand is suggested, which is simple to manufacture and which greatly improves the reproducibility of the test results. Dynamic fracture mechanics analyses of artificial crack-like defects in the test objects were performed by means of finite-element calculations to uncover safety margins. Numerous test results have shown that containers for final disposal can be built from a ductile cast iron with a fracture toughness of more than 50 per cent less than the current lower bound value for the licensed material. The limits of application of the material are also determined by the opportunities for safety assessment. (author)

    The mechanical behaviour of transport and storage containers made of ductile cast iron melted with higher content of metallic recycling material from decommissioning and dismantling of nuclear installations is investigated. With drop tests of cubic container-like models, the influence of different real targets on the stresses in the cask body and the fracture behaviour is examined. A test stand foundation is suggested, which can be manufactured simply and improves the reproducibility of the test results strongly. The test objects are partially equipped with artificial cracklike defects. Dynamic fracture mechanics analyses of these defects were performed by means of finite element calculations to uncover safety margins. Numerous test results show depending on the requirements that containers for final disposal can be built by means of a ductile cast iron with fracture toughness more than half under the lower bound value for the licensed material qualities yet. The application limits of the material are determined also by the opportunities of the safety assessment methods. This project supports the application of brittle fracture safe transport and storage packages for radioactive materials as recommended in App. VI of the Advisory Material for the IAEA Regulations for the Safe Transport of Radioactive Material (IAEA No. TS-G-1.1)

    Full Text Available There is a lack of research on the everyday lives of older people in developing countries. This exploratory study used structured observation and content analysis to examine the presence of older people in public fora and considered the methods’ potential for understanding older people’s social integration and inclusion. Structured observation occurred of public social spaces in six cities each located in a different developing country and in one city in the United Kingdom, together with content analysis of the presence of people in newspaper pictures and on television in the selected countries. Results indicated that across all fieldwork sites and data sources, there was a low presence of older people, with women considerably less present than men in developing countries. There was variation across fieldwork sites in older people’s presence by place and time of day and in their accompanied status. The presence of older people in images drawn from newspapers was associated with the news/non-news nature of the source. The utility of the study’s methodological approach is considered, as is the degree to which the presence of older people in public fora might relate to social integration and inclusion in different cultural contexts.

    2005-04-01

    The article describes the status of our ongoing R&D at the U.S. National Library of Medicine (NLM) towards the development of an advanced multimedia database biomedical information system that supports content-based image retrieval (CBIR). NLM maintains a collection of 17,000 digitized spinal X-rays along with text survey data from the Second National Health and Nutritional Examination Survey (NHANES II). These data serve as a rich data source for epidemiologists and researchers of osteoarthritis and musculoskeletal diseases. It is currently possible to access these through text keyword queries using our Web-based Medical Information Retrieval System (WebMIRS). CBIR methods developed specifically for biomedical images could offer direct visual searching of these images by means of example image or user sketch. We are building a system which supports hybrid queries that have text and image-content components. R&D goals include developing algorithms for robust image segmentation for localizing and identifying relevant anatomy, labeling the segmented anatomy based on its pathology, developing suitable indexing and similarity matching methods for images and image features, and associating the survey text information for query and retrieval along with the image data. Some highlights of the system developed in MATLAB and Java are: use of a networked or local centralized database for text and image data; flexibility to incorporate new research work; provides a means to control access to system components under development; and use of XML for structured reporting. The article details the design, features, and algorithms in this third revision of this prototype system, CBIR3.

    Two austenitic steels, Fe-21.3Mn-3.44Si-3.74Al-0.5C and Fe-29.8Mn-2.96Si-2.73Al-0.52C, were subjected to cold rolling with 30 to 80 pct reduction with an increment of 10 pct and subsequently the development of their microstructures and textures were studied. The overall texture after 80 pct cold reduction was Brass type. A weak Copper component {112} was present at the early stage of deformation, which disappeared completely after 60 pct cold reduction. Extensive shear banding took place in both the steels, right from rather low cold rolling levels, which became more prominent at higher amounts of cold rolling. Formation of twin bands, along with cellular dislocation network, was observed in Steel A after 30 pct cold rolling. In case of Steel B, denser twin bands and dislocation cellular network were observed in early stage of deformation. After 80 pct cold reduction, the development of a strong brass-type texture in both the steels could be attributed predominantly to the formation of shear banding, possibly with some partial contribution coming from micro twinning.

    2010-05-01

    The development of new rodent models of human disease and advances in surgical equipment and technologies have increased the demand for expertise in rodent surgery. Because of the limited availability of rodent surgical training courses, electronic (e-) learning is presented as an alternative to in-person education and as a means to hone the expertise of current surgeons in biomedical research, similar to e-learning applications for human surgery training. Translating this model to the biomedical research field provides participants with an opportunity to train themselves on rodent surgical techniques prior to operating on live models. An e-learning rodent surgery course was incorporated into a training class of undergraduate (n = 39) and graduate (n = 12) laboratory animal students, and a portion of the course was presented to laboratory animal professionals (n = 15). The effectiveness of the method was evaluated using written examination and postcourse surveys. The exam data demonstrated that the e-learning course transferred knowledge comparable to a lecture course on surgery that was presented in-person. Students responded favorably to videos, step-by-step photographs of surgical procedures, and the ready accessibility of the course. Critiques included the need to improve video resolution and quality of the voice-overs. These results support the continued development and implementation of electronic rodent surgical technique courses for use in laboratory animal and biomedical research communities. PMID:20587161

  5. Development of a High-Content Orthopoxvirus Infectivity and Neutralization Assays.

    Directory of Open Access Journals (Sweden)

    Irina Gates

    Full Text Available Currently, a number of assays measure Orthopoxvirus neutralization with serum from individuals, vaccinated against smallpox. In addition to the traditional plaque reduction neutralization test (PRNT, newer higher throughput assays are based on neutralization of recombinant vaccinia virus, expressing reporter genes such as β-galactosidase or green fluorescent protein. These methods could not be used to evaluate neutralization of variola virus, since genetic manipulations of this virus are prohibited by international agreements. Currently, PRNT is the assay of choice to measure neutralization of variola virus. However, PRNT assays are time consuming, labor intensive, and require considerable volume of serum sample for testing. Here, we describe the development of a high-throughput, cell-based imaging assay that can be used to measure neutralization, and characterize replication kinetics of various Orthopoxviruses, including variola, vaccinia, monkeypox, and cowpox.

Rather than starting in the problematic present, SitCit takes its starting point in the desired future. Through developing scenarios of more sustainable futures and connecting these to the present, the project aims at identifying and innovating potentials for a less environmentally burdening urban life. Energy use and CO{sub 2} are the main focus, but through a complementary qualitative sustainability assessment other aspects of sustainability are also included. The scenario methodology is comprised of three separate but interconnected parts. In the Scenario Content the question what could change is at the centre, and the potential changes are sought in the physical, institutional, and socio-cultural structures of buildings, transport and citizens' everyday life. Fundamental to the Scenario Content is an iterative identification of objects and actors of change. The Scenario Outcome focuses on the question of how much energy use could be decreased through these changes. This is estimated through modelling the scenario contents in terms of energy usage systems. In the Scenario Process the question of how the changes could be achieved is explored through elaborating the identified actors into a dimension of governance in the scenarios. Figure 1 presents an overview of the methodology and its integral parts. In SitCit, the methodology is developed through three scenario studies focusing on green mobility in Bromma, ICT solutions in Soedermalm and energy efficiency through refurbishment in Rinkeby-Kista. These three Stockholm City Districts all have their specific urban morphological and demographical characteristics and are chosen for contrast. This report presents the study focusing on green mobility

    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

    Droplet-based microfluidic platforms sequester nanoliter to picoliter samples in an immiscible carrier phase and have gained notoriety for their ability to be used in laboratory procedures on a miniaturized scale. Recently, droplet microfluidics has been used to prevent zone diffusion in time-resolved sample collection methods and in separation techniques. The assay of droplets remains challenging, however, because the carrier phase is often incompatible with separation techniques. In this work, we report the development of a droplet injector for capillary electrophoresis (CE) which delivers 750 pL droplets to a channel for separation while excluding the fluorous carrier phase. This design is simple compared to previous reports, consisting of only two straight channels and no additional working parts such as membranes or valves. To demonstrate a proof-of-concept and characterize performance, riboflavin was used as a biologically relevant model molecule. Droplets containing a step change in riboflavin concentration were injected and mobilized by CE. The current method is capable of riboflavin peak % relative standard deviations (RSDs) down to 4.4% and temporal resolutions down to 15 s. Human urine samples containing riboflavin and its photolysis products were successfully separated and found to be chemically compatible with the injector. Our simplified design could improve robustness and ruggedness and may allow device construction via nontraditional fabrication techniques. PMID:25226066

    Exosomes and microvesicles (i.e., extracellular vesicles: EVs) have been identified within ovarian follicular fluid and recent evidence suggests that EVs are able to elicit profound effects on ovarian cell function. While existence of miRNA within EVs has been reported, whether EV size and concentration as well as their cargos (i.e., proteins and RNA) change during antral follicle growth remains unknown. Extracellular vesicles isolated from follicular fluid of small, medium and large bovine follicles were similar in size, while concentration of EVs decreased progressively as follicle size increased. Electron microscopy indicated a highly purified population of the lipid bilayer enclosed vesicles that were enriched in exosome biomarkers including CD81 and Alix. Small RNA sequencing identified a large number of known and novel miRNAs that changed in the EVs of different size follicles. Ingenuity Pathway Analysis (IPA) indicated that miRNA abundant in small follicle EV preparations were associated with cell proliferation pathways, while those miRNA abundant in large follicle preparations were related to inflammatory response pathways. These studies are the first to demonstrate that EVs change in their levels and makeup during antral follicle development and point to the potential for a unique vesicle-mediated cell-to-cell communication network within the ovarian follicle.

    Lightsticks are artifacts used as attractors in a type of commercial fishery, known as surface longline gear. Despite the excessive use, the contamination risks of these devices have not yet been properly investigated. This research aimed to fill up this gap by determining the chemical composition and the toxicity of lightsticks recently activated, compared to those one year after activation and to the ones collected on the beaches. The analyzes were carried out by Gas Chromatography coupled with Mass Spectrometry (GC-MS). Additionally, the variations in composition and the toxicity of their sea Water Soluble Fractions (WSF) were evaluated based on the WSF-effects of Crassostrea rhizophorae embryonic development. The GC-MS analysis made possible the identification of nineteen substances in the water soluble fraction of the lightsticks, such as dibutyl phthalate (DBP) and dimethyl phthalate (DMP). The value of the WSF-effective concentration (EC50) was in an average of 0.35%. After one year of the lightsticks activation, the toxicity was even higher (0.65%). Furthermore, other substances, also present in the lightsticks-WSF caused persistent toxicity even more dangerous to the environment than DBP and DMP. This essay discusses their toxicity effects and possible environment damages. PMID:26070145

    Community opposition is a barrier to potable recycled water schemes. Effective communication strategies about such schemes are needed. Drawing on social psychological literature, two experimental studies are presented, which explore messages that improve public perceptions of potable recycled water. The Elaboration-Likelihood Model of information processing and attitude change is tested and supported. Study 1 (N = 415) premeasured support for recycled water, and trust in government information at Time 1. Messages varied in complexity and sidedness were presented at Time 2 (3 weeks later), and support and trust were remeasured. Support increased after receiving information, provided that participants received complex rather than simple information. Trust in government was also higher after receiving information. There was tentative evidence of this in response to two-sided messages rather than one-sided messages. Initial attitudes to recycled water moderated responses to information. Those initially neutral or ambivalent responded differently to simple and one-sided messages, compared to participants with positive or negative attitudes. Study 2 (N = 957) tested the effectiveness of information about the low relative risks, and/or benefits of potable recycled water, compared to control groups. Messages about the low risks resulted in higher support when the issue of recycled water was relevant. Messages about benefits resulted in higher perceived issue relevance, but did not translate into greater support. The results highlight the importance of understanding people's motivation to process information, and need to tailor communication to match attitudes and stage of recycled water schemes' development.

  14. Development of Criteria for Flameholding Tendencies within Premixer Passages for High Hydrogen Content Fuels

    2015-03-31

    Due to increasingly stringent air quality requirements stationary power gas turbines have moved to lean-premixed operation, which reduces pollutant emissions but can result in flashback. Flashback can cause serious damage to the premixer hardware. Curtailing flashback can be difficult with hydrocarbon fuels and becomes even more challenging when hydrogen is used as the fuel. The two main approaches for coping with flashback are either to design a combustor that is resistant to flashback, or to design a premixer that will not anchor a flame if flashback occurs. Even with a well-designed combustor flashback can occur under certain circumstances, thus it is necessary to determine how to avoid flameholding within the premixer passageways of a gas turbine. To this end, an experiment was designed that would determine the flameholding propensities at elevated pressures and temperatures of three different classes of geometric features commonly found in gas turbine premixers, with both natural gas and hydrogen fuel. Experiments to find the equivalence ratio at blow off were conducted within an optically accessible test apparatus with four flameholders: 0.25 and 0.50 inch diameter cylinders, a reverse facing step with a height of 0.25 inches, and a symmetric airfoil with a thickness of 0.25 inches and a chord length of one inch. Tests were carried out at temperatures between 300 K and 750 K, at pressures up to 9 atmospheres. Typical bulk velocities were between 40 and 100 m/s. The effect of airfoil’s angle of rotation was also investigated. Blow off for hydrogen flames was found to occur at much lower adiabatic flame temperatures than natural gas flames. Additionally it was observed that at high pressures and high turbulence intensities, reactant velocity does not have a noticeable effect on the point of blow off due in large part to corresponding increases in turbulent flame speed. Finally a semi empirical correlation was developed that predicts flame extinction for both

    Full Text Available Development of Mentha piperita L . on biosolids amended soil with levels equivalent to 0, 28, 56 and 112 t ha-1 was evaluated. In order to measure the productivity and its relation with mint essential oil yield, different indices were determined: leaf area, total and several organ dry matter, leaf area ratio, specific leaf area, net assimilation rate and relative growth rate at 30, 44, 58, 72 and 86 days after planting (DAP, and essential oil yield at 90, 110 and 120 DAP. Physiological indices revealed that biosolids prolonged the vegetative phase of the plants, which adapted themselves to the presence of biosolids with time. Plants showed inverse behaviors in relation to productivity, resulting from the primary metabolism, represented by the shoot dry matter yield, and oil yield, resulting from the secondary metabolism. Adaptation of the mint plants to the growth on biosolids could be due to a phytoremediation function of this species. The intrinsic mechanisms of these processes could be better understood in a further evaluation of residual effects in mint plant shoots.Níveis de biossólido equivalentes a 0, 28, 56 e 112 t ha-1 foram avaliados no desenvolvimento de Mentha piperita L.

    only be performed at a reactor. The measurement technique based on a stationary neutron generated has not been exploited yet. The purpose of the present measurements was the investigation of the accuracy of the neutron generator based method. The results of measurement and calculation show the suitability of the method applied for the determination of the volume porosity. Yet another interesting non-intrusive nuclear technique, based on the pulsed neutron activation for the measurement of mass flow of water (the FlowAct method), constitutes the third subject of this thesis. High accuracy of the FlowAct method demands a detailed understanding of the turbulent flow, and the analysis of a FlowAct measurement is a complex problem. In order to obtain high precision measurement of water flow, the effect of different parameters in the experimental set-up has to be understood. The following particular problems were investigated in detail: a) the effect of collimation of a neutron source and detector on the time-resolved detector signals; b) the behaviour of the background time distribution signal to expedite optimum elimination from the measured signals; and, c) the properties of water mixing, by measuring the geometrical asymmetry of the activated volume as a function of distance from the source as well as flow velocity. The current results are promising for the further development of the method towards a high-precision flow rate measurement

  19. Pedagogical content knowledge development in teaching science: A case study of an elementary school teacher in an urban classroom

    Suh, Yewon

    This study aims to explore an elementary school teacher's Pedagogical Content Knowledge (PCK) development in teaching science to racial minorities and economically disadvantaged students in New York City. By taking into account the sociocultural issues of teaching science in urban areas, this study focuses on 'contextual knowledge' as a key component of PCK. In this study, PCK is conceptualized as transformed knowledge of subject matter, pedagogy, and context, which makes subject learning suitable for students in particular settings. In order to investigate the teacher's PCK development, this study first examines her existing knowledge base of PCK in terms of three knowledge domains, and then observes her PCK development through the relationship between contextual knowledge and other two knowledge domains during classroom practices. A case study method was used to obtain a holistic and in-depth understanding of the teacher's PCK development. Data were collected in the form of teacher interview, participant observation, documentation, and physical artifacts, to enrich the case, and was analyzed in an inductive process. Findings illustrate the ways that the three knowledge domains are related and developed as PCK through the whole teaching process. Specifically, the findings indicate that the teacher's contextual knowledge plays a critical role in shaping and developing PCK. The teacher's contextual knowledge about the administrative policies and school test system in the district facilitated her to make a decision and plan to teach science before the instruction. During the classroom teaching, her knowledge about students' sociocultural backgrounds and living conditions in an urban setting helped her to identify specific teaching strategies and resources suitable to students' needs and interests. These findings imply that science teaching can be meaningful in coping with the demands of diverse learning populations if teachers make an effort to become knowledgeable

    Power transformers are essential for a functioning electrical system and therefore require special attention by maintenance programs because a fault can harm both the company and society. The temperature inside a power transformer and the dissolved gases, which are primarily composed of acetylene, are the two main parameters monitored when detecting faults. This paper describes the development of a device for analyzing the acetylene content in insulating oil using spectrofluorimetry. Using this device introduces a new methodology for the maintaining and operating power transformers. The prototype is currently operating in a substation. The results presented by this system were satisfactory; when compared to chromatographic data, the errors did not exceed 15%. This prototype may be used to confirm the quality of an insulating oil sample to detect faults in power transformers. PMID:24209339

    Full Text Available Abstract Background Mammals are essentially born germ-free but the epithelial surfaces are promptly colonized by astounding numbers of bacteria soon after birth. The most extensive microbial community is harbored by the distal intestine. The gut microbiota outnumber ~10 times the total number of our somatic and germ cells. The host-microbiota relationship has evolved to become mutually beneficial. Studies in germ-free mice have shown that gut microbiota play a crucial role in the development of the immune system. The principal aim of the present study was to elucidate whether the presence of gut microbiota and the quality of a sterile diet containing various amounts of bacterial contaminants, measured by lipopolysaccharide (LPS content, can influence maturation of the immune system in gnotobiotic mice. Results We have found that the presence of gut microbiota and to a lesser extent also the LPS-rich sterile diet drive the expansion of B and T cells in Peyer's patches and mesenteric lymph nodes. The most prominent was the expansion of CD4+ T cells including Foxp3-expressing T cells in mesenteric lymph nodes. Further, we have observed that both the presence of gut microbiota and the LPS-rich sterile diet influence in vitro cytokine profile of spleen cells. Both gut microbiota and LPS-rich diet increase the production of interleukin-12 and decrease the production of interleukin-4. In addition, the presence of gut microbiota increases the production of interleukin-10 and interferon-γ. Conclusion Our data clearly show that not only live gut microbiota but also microbial components (LPS contained in sterile diet stimulate the development, expansion and function of the immune system. Finally, we would like to emphasize that the composition of diet should be regularly tested especially in all gnotobiotic models as the LPS content and other microbial components present in the diet may significantly alter the outcome of experiments.

    Full Text Available Abstract Background Patients receiving complementary and alternative medicine (CAM therapies often report shifts in well-being that go beyond resolution of the original presenting symptoms. We undertook a research program to develop and evaluate a patient-centered outcome measure to assess the multidimensional impacts of CAM therapies, utilizing a novel mixed methods approach that relied upon techniques from the fields of anthropology and psychometrics. This tool would have broad applicability, both for CAM practitioners to measure shifts in patients' states following treatments, and conventional clinical trial researchers needing validated outcome measures. The US Food and Drug Administration has highlighted the importance of valid and reliable measurement of patient-reported outcomes in the evaluation of conventional medical products. Here we describe Phase I of our research program, the iterative process of content identification, item development and refinement, and response format selection. Cognitive interviews and psychometric evaluation are reported separately. Methods From a database of patient interviews (n = 177 from six diverse CAM studies, 150 interviews were identified for secondary analysis in which individuals spontaneously discussed unexpected changes associated with CAM. Using ATLAS.ti, we identified common themes and language to inform questionnaire item content and wording. Respondents' language was often richly textured, but item development required a stripping down of language to extract essential meaning and minimize potential comprehension barriers across populations. Through an evocative card sort interview process, we identified those items most widely applicable and covering standard psychometric domains. We developed, pilot-tested, and refined the format, yielding a questionnaire for cognitive interviews and psychometric evaluation. Results The resulting questionnaire contained 18 items, in visual analog scale format

    Full Text Available Poetic folk literature products make important contributions to the mother tongue education and Turkish to be learned effectively. Lullabies, folk songs, ballads, tongue twisters, word puzzles and people songs introduce children with the word existence of mother tongue. The literature products help children learn Turkish, the mother tongue, effectively in the sensory-motor and preoperational stages of development.  Native language education through the culture also contributes to the awareness of language and nationality. The classification of the folk literature products according to  children’s development and maturation phases,  their sensation-opinion adequacies, their tastes and habits, their dream worlds and their usage as a material of children’s literature with scientific methods depend on in common tries of language teachers, pedagogs, educational researchers  and psychologists. In this study first lullabies are defined and classified. Then, effects of the lullabies on the development of children’s mother tongue are investigated. Later, in the vicinities of  Konya, 62 lullabies are compiled by face to face interview method, and content analysis of these lullabies are made to determine to what domains of children they effect. As a final remark, some suggestions concerning lullaby selection and singing made to those who may concern.

  6. Effects of ABA Content on the Development of Abscission Zone and Berry Falling After Harvesting of Grapes

    The commodity price of grape reduces as berry falling after harvest. It is crucial to prevent grape from berry falling during storage. In this article, the structure change of grape cells in the abscission zone was observed, the ABA content and the activities of cellulase and polygalacturonase (PG) were measured, and the relationship of ABA and berry falling was investigated. The results suggest that cells in the abscission zone grow into a separation layer soon after the grapes are cut off. According to the level of development, we designed 6 grades to sort the different development stages. The grade 3 plays an important role in berry falling. ABA enhances the activities of cellulase and polygalacturonase, and accelerates the decomposition of cellulose and pectin, which determines the level of development of abscission zone and berry falling. If ABA ratio is less than 20 ng g-1 fresh weight (FW), the abscission zone is not developed to the grade 3, and the berry falling is effectively stopped. We treated grape bunches with nine plant growth regulators and two chemicals. The results indicated that 2,3,5-triiodobenzoic acid (TIBA) can (a) inhibit the generation of ABA significantly, (b) inactivate the activities of cellulase and PG, (c) delay the development of the grade 3 of abscission zone, and (d) stop berry falling. Indole acetic acid (IAA), gibberellic acid (GA3), naphthalene acetic acid (NAA), 6-benzylaminopurine (6-BA), calcium chloride (CaCl2), and potassium permanganate (KMnO4) caused similar results as TIBA. Chlorocholine chloride (CCC), dimethyl amino succinamic acid (B9), chloroethylphosphonic acid (CEPA) and exogenous ABA showed opposite effects.

    Background Language reflects the state of one’s mental health and personal characteristics. It also reveals preoccupations with a particular schema, thus possibly providing insights into psychological conditions. Using text or lexical analysis in exploring depression, negative schemas and self-focusing tendencies may be depicted. As mobile technology has become highly integrated in daily routine, mobile devices have the capacity for ecological momentary assessment (EMA), specifically the experience sampling method (ESM), where behavior is captured in real-time or closer in time to experience in one’s natural environment. Extending mobile technology to psychological health could augment initial clinical assessment, particularly of mood disturbances, such as depression and analyze daily activities, such as language use in communication. Here, we present the process of lexicon generation and development and the initial validation of Psychologist in a Pocket (PiaP), a mobile app designed to screen signs of depression through text analysis. Objective The main objectives of the study are (1) to generate and develop a depressive lexicon that can be used for screening text-input in mobile apps to be used in the PiaP; and (2) to conduct content validation as initial validation. Methods The first phase of our research focused on lexicon development. Words related to depression and its symptoms based on the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) and in the ICD-10 Classification of Mental and Behavioural Disorders: Clinical Descriptions and Diagnostic Guidelines classification systems were gathered from focus group discussions with Filipino college students, interviews with mental health professionals, and the review of established scales for depression and other related constructs. Results The lexicon development phase yielded a database consisting of 13 categories based on the criteria depressive symptoms in the DSM-5 and ICD-10. For

  8. Development of a specific monoclonal antibody-based ELISA to measure the artemether content of antimalarial drugs.

    Full Text Available Artemether is one of the artemisinin derivatives that are active ingredients in antimalarial drugs. Counterfeit and substandard antimalarial drugs have become a serious problem, which demands reliable analytical tools and implementation of strict regulation of drug quality. Structural similarity among artemisinin analogs is a challenge to develop immunoassays that are specific to artemisinin derivatives. To produce specific antibodies to artemether, we used microbial fermentation of artemether to obtain 9-hydroxyartemether, which was subsequently used to prepare a 9-O-succinylartemether hapten for conjugation with ovalbumin as the immunogen. A monoclonal antibody (mAb, designated as 2G12E1, was produced with high specificity to artemether. 2G12E1 showed low cross reactivities to dihydroartemisinin, artemisinin, artesunate and other major antimalarial drugs. An indirect competitive enzyme linked immunosorbent assay (icELISA developed showed a concentration causing 50% of inhibition for artemether as 3.7 ng mL⁻¹ and a working range of 0.7-19 ng mL⁻¹. The icELISA was applied for determination of artemether content in different commercial drugs and the results were comparable to those determined by high-performance liquid chromatography analysis. In comparison with reported broad cross activity of anti-artemisinin mAbs, the most notable advantage of the 2G12E1-based ELISA is its high specificity to artemether only.

    The aim of the project 'Development of methods for determination of PAH based on measured CO-content' is to investigate the possibility to develop a method for continuous optimisation of NO{sub x}-emissions by decreased air ratio, without significant increase of polyaromatic hydrocarbons such as PAH. The general idea has been to find a indirect online method to predict the emissions of heavier hydrocarbons by: - creating a correlation between the content of CO and PAH, - controlling the air ratio by the CO-content, and - integrating the calculated PAH-content from CO-content. Today many boilers are operated with a low air ratio to minimise the NO{sub x} content and the NO{sub x}-fee. A low ratio increases the risk of high CO contents in the flue gas as well as increased contents of VOC and PAH. Other boilers are operated with high air ratios in order to minimise the CO content, which in some cases will result in unnecessary high NO{sub x} emissions. One of the main difficulties in optimising the air ratio to the most environmental friendly level is the lack of a suitable and well proven PAH instrument. There are today no available instruments for instantaneous and continuous measurement of PAH. PAH is normally measured as an average value during a period of at least one hour. It is not possible to detect short peaks. The development of the CO-method has been based on data from a CFB-boiler in Korsta in Sundsvall (Vaermeforskrapport 541). The data shows a clear correlation between THC and CO. The correlation seems to be mostly dependent of moisture content and load. The development presented in the report shows that it is possible to find a method to predict the PAH content from the CO-content in the flue gas. The next phase aims to improve and implement the method, by measurements and adaptation in a plant. The practical use of the method is as a tool to optimise the emission of CO, NO{sub x}, THC and PAH and/or to predict the PAH-emission during

    We have provided two years of professional development for secondary and middle school teachers with a focus on project-based instruction (PBI) using GIS. The EYE-POD project (funded by NSF-ITEST) involved pairs of teachers from Arizona and the surrounding region in two-week institutes during Summer, 2010, and an advanced institute in Summer, 2011. The NAz-POD project (funded by Arizona Department of Education and administered by Science Foundation Arizona) provided similar PD experiences, but the institutes occurred during weekends in the academic year. The institutes were led by a team with expertise in Earth science content, professional development and pedagogy, and GIS. The teachers developed learning modules using the project based learning instructional model. Pedagogy, content, and GIS skills were combined throughout the professional development activities. Academic year follow up by NAU personnel included classroom observations and technical support. For assessing student work we provided a rubric, but learned that teachers were not prepared to assess GIS products in order to determine the level of student understanding. In year two of the project we incorporated strategies for assessment of student products into the professional development. Teacher-participants and their students completed several pre- and post- assessments. Teacher assessments included a geospatial performance assessment, classroom observations, and content tests. Student data collection included attitude and efficacy questionnaires, content tests, and authentic assessments including products using GIS. Content tests were the same for teachers and students and included spatial reasoning, data analysis, and Earth science content. Data was also collected on teacher perception of professional development delivery and self-reported confidence in teaching with PBI and geospatial technology. Student assessments show that improvement occurred in all areas on the content test. Possible factors

    Full Text Available Background: Limited tools exist to measure handwriting readiness skills of pre-kindergarten students. This study was a preliminary exploration of content validity of the Shore Handwriting Screening (SHS and the newly developed Score Sheet with the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOT-2 in 4- and 5-year-old pre-kindergarten students. Because socioeconomic status (SES is known to impact handwriting skills, data from two different socioeconomic groups were collected. Method: Students from a Lower SES group (n = 36 and a Higher SES group (n = 14 completed the SHS and fine motor composite of the BOT-2. Pearson’s correlation was used to compare scores on the two assessments within the two groups. Results: SHS overall percentage scores were compared to standard scores and composite scores of the BOT-2. SHS scores displayed moderate to high correlation with fine manual control portions of the BOT-2 for the Lower SES group and low to moderate correlation for the same portion in the Higher SES group. Conclusion: SHS and the Score Sheet correlate to fine and visual-motor skill subtests on the fine manual control portions of the BOT-2, which supports the need for further research on the reliability and validity of the Score Sheet for use in practice.

    The inclusion of intact phospholipids in the diet is essential during larval development and can improve culture performance of many fish species. The effects of supplementation of dietary phospholipid from marine (krill) or plant (soy lecithin) sources were investigated in Atlantic salmon, Salmo salar. First feeding fry were fed diets containing either krill oil or soybean lecithin supplying phospholipid at 2.6%, 3.2%, 3.6% and 4.2% of diet. Fish were sampled at ~ 2.5 g (~1,990°day post fertilization, dpf) and ~10 g (2,850°dpf). By comparison of the intestinal transcriptome in specifically chosen contrasts, it was determined that by 2,850°dpf fish possessed a profile that resembled that of mature and differentiated intestinal cell types with a number of changes specific to glycerophospholipid metabolism. It was previously shown that intact phospholipids and particularly phosphatidylcholine are essential during larval development and that this requirement is associated with the inability of enterocytes in young fry to endogenously synthesize sufficient phospholipid for the efficient export of dietary lipid. In the immature phase (~1,990°dpf), the dietary phospholipid content as well as its class composition impacted on several biochemical and morphological parameters including growth, but these differences were not associated with differences in intestinal transcriptomes. The results of this study have made an important contribution to our understanding of the mechanisms associated with lipid transport and phospholipid biosynthesis in early life stages of fish.

    Effects of tungsten and tantalum contents on impact, tensile, low cycle fatigue and creep properties of Reduced Activation Ferritic-Martensitic (RAFM) steel were studied to develop India-specific RAFM steel. Four heats of the steel have been melted with tungsten and tantalum contents in the ranges 1-2 wt.% and 0.06-0.14 wt.% respectively. Increase in tungsten content increased the ductile-to-brittle transition temperature (DBTT), low cycle fatigue and creep strength of the steel, whereas the tensile strength was not changed significantly. Increase in tantalum content increased the DBTT and low cycle fatigue strength of the steel whereas the tensile and creep strength decreased. Detailed TEM investigations revealed enhanced microstructural stability of the steel against creep exposure on tungsten addition. The RAFM steel having 1.4 wt.% tungsten with 0.06 wt.% tantalum was found to possess optimum combination of impact, tensile, low cycle fatigue and creep properties and is considered for Indian-specific RAFM steel. Low temperature impact energy of the RAFM steel is quite sensitive to the contents of tungsten and tantalum. The DBTT increased with both the tungsten and tantalum contents. Tungsten and tantalum contents in the investigated ranges had no appreciable effect on the tensile properties of the RAFM steel. Low cycle fatigue life of the RAFM steel increased with the increase in tungsten and tantalum contents. The softening rate with cyclic exposure was lowest for tungsten content of 1.4 wt.%, further increase in tungsten led to an increase in softening rate. Creep deformation and rupture strength of the RAFM steel were found to be quite sensitive to the tungsten and tantalum contents. Creep strength of the steel increased with increase in tungsten content and decreased with increase in tantalum content. Based on the study, the chemical composition of India-specific RAFM steel has been established as 9Cr-1.4W-0.06Ta-V, having optimum combination of strength and

  19. Effect of lead content on phase evolution and microstructural development in Ag-clad Bi-2223 composite conductors

    International Nuclear Information System (INIS)

    A two powder process was used to prepare silver-sheathed monofilamentary Bi1.8PbxSr1.98Ca1.97Cu3.08Oy (Bi-2223) tapes with varying lead contents, x, from 0.2 to 0.5. The resulting tapes were subjected to thermomechanical processing and then characterized by x-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive x-ray analysis (EDX). Layered phase texture was accessed using image analysis software on scanned SEM micrographs. Transport currents were measured at 77 K and zero field by the four-probe method. It was found that tapes with low lead content (X = 0.2 and 0.25) showed incomplete conversion to Bi-2223, had small grain size and poor c-axis texture. Tapes having higher lead content (x = 0.4 and 0.5) also showed incomplete conversion and the presence of lead-rich secondary phases. Tapes with lead content x = 0.3 and 0.35 showed complete conversion to Bi-2223, and had the least amount of secondary phases, the best c-axis texture, and the highest transport current (jc). The carbon content of the precursor powder also had a strong influence on secondary-phase chemistry

    This paper presents the development of a substitute product for the aromatic oil used in rubber tires. The new oil must be in according to The European Community Directive 2005/69/EC, which has the start date in January first of 2010. The directive sets limits for specific levels of polyaromatics content in the oils for rubber tires because of the mutagenic and harmful to the reproduction characteristic of some of these substances. The process of aromatics extraction was conducted on several kinds of feedstocks to obtain a product with kinematic viscosity at 100 deg C in the 40-50 cSt range and polycyclics aromatics content until 3% in mass. It is important to know that the current oils have 20% in mass of polyaromatics content. The product developed is in according with the Directive specifications and contributes to the production of tires more suitable to the environment and human health. (author)

    2015-01-01

    We report a panel designed to open a dialog between pharmaceutical sponsors, regulatory reviewers, and other stakeholders regarding the use of social media to collect data to support the content validity of patient-reported outcome instruments in the context of medical product labeling. Multiple stakeholder perspectives were brought together to better understand the issues encountered in pursuing social media as a form of data collection to support content validity. Presenters represented a pharmaceutical sponsor of clinical trials, a regulatory reviewer from the Food and Drug Administration, and an online data platform provider. Each presenter shared its perspective on the advantages and disadvantages of using social media to collect this type of information. There was consensus that there is great potential for using social media for this purpose. There remain, however, unanswered questions that need to be addressed such as identifying which type of social media is most appropriate for data collection and ensuring that participants are representative of the target population while maintaining the advantages of anonymity provided by online platforms. The use of social media to collect evidence of content validity holds much promise. Clarification of issues that need to be addressed and accumulation of empirical evidence to address these questions are essential to moving forward. PMID:25595228

  10. Developing palaeolimnological records of organic content (DOC and POC) using the UK Acid Water Monitoring Network sites

    Russell, Fiona; Chiverrell, Richard; Boyle, John

    2016-04-01

    Monitoring programmes have shown increases in concentrations of dissolved organic matter (DOM) in the surface waters of northern and central Europe (Monteith et al. 2007), and negative impacts of the browning of river waters have been reported for fish populations (Jonsson et al. 2012; Ranaker et al. 2012) and for ecosystem services such as water treatment (Tuvendal and Elmqvist 2011). Still the exact causes of the recent browning remain uncertain, the main contenders being climate change (Evans et al. 2005) and reduced ionic strength in surface water resulting from declines in anthropogenic sulphur and sea salt deposition (Monteith et al. 2007). There is a need to better understand the pattern, drivers and trajectory of these increases in DOC and POC in both recent and longer-term (Holocene) contexts to improve the understanding of carbon cycling within lakes and their catchments. In Britain there are some ideal sites for testing whether these trends are preserved and developing methods for reconstructing organic fluxes from lake sedimentary archives. There is a suite of lakes distributed across the country, the UK Acid Waters Monitoring Network (UKAWMN) sites, which have been monitored monthly for dissolved organic carbon and other aqueous species since 1988. These 12 lakes have well studied recent and in some case whole Holocene sediment records. Here four of those lakes (Grannoch, Chon, Scoat Tarn and Cwm Mynach) are revisited, with sampling focused on the sediment-water interface and very recent sediments (approx.150 years). At Scoat Tarn (approx. 1000 years) and Llyn Mynach (11.5k years) longer records have been obtained to assess equivalent patterns through the Holocene. Analyses of the gravity cores have focused on measuring and characterising the organic content for comparison with recorded surface water DOC measurements (UKAWMN). Data from pyrolysis measurements (TGA/DSC) in an N atmosphere show that the mass loss between 330-415°C correlates well with

    2006-01-01

    Full Text Available Abstract Background Robust, programmatically accessible biomedical information services that syntactically and semantically interoperate with other resources are challenging to construct. Such systems require the adoption of common information models, data representations and terminology standards as well as documented application programming interfaces (APIs. The National Cancer Institute (NCI developed the cancer common ontologic representation environment (caCORE to provide the infrastructure necessary to achieve interoperability across the systems it develops or sponsors. The caCORE Software Development Kit (SDK was designed to provide developers both within and outside the NCI with the tools needed to construct such interoperable software systems. Results The caCORE SDK requires a Unified Modeling Language (UML tool to begin the development workflow with the construction of a domain information model in the form of a UML Class Diagram. Models are annotated with concepts and definitions from a description logic terminology source using the Semantic Connector component. The annotated model is registered in the Cancer Data Standards Repository (caDSR using the UML Loader component. System software is automatically generated using the Codegen component, which produces middleware that runs on an application server. The caCORE SDK was initially tested and validated using a seven-class UML model, and has been used to generate the caCORE production system, which includes models with dozens of classes. The deployed system supports access through object-oriented APIs with consistent syntax for retrieval of any type of data object across all classes in the original UML model. The caCORE SDK is currently being used by several development teams, including by participants in the cancer biomedical informatics grid (caBIG program, to create compatible data services. caBIG compatibility standards are based upon caCORE resources, and thus the caCORE SDK has

    International Nuclear Information System (INIS)

    Reduction of the contents of waste in glass from 20-25% to 9% causes a decrease of the leaching resistance of the glass. The addition of Zn0 reduces the leaching values by a factor of approximately 10. The crystallized glass ceramics have a lower coefficient of thermal expansion than glassy waste bodies. The separation of the phase which contains Mo occurs during heat treatment. The amount of separated Mo is lower for low alkali sac type (Si02 - A1203-Ca0 system) of glasses by a factor of approximately 50. All the glasses were prepared with simulated waste composition.

    The precise knowledge of the water content in geological samples such as mantle minerals, volcanic glasses and glassy inclusions proves to be crucial information for the Earth Sciences because water has a considerable influence on physical and chemical properties of Earth's mantle and crust. Among the nuclear microbeam techniques, elastic recoil detection analysis (ERDA) has been used at the nuclear microprobe of the Pierre Süe Laboratory (LPS) with a very good reliability for a long time to determine the water content of various materials. Previous ERDA measurements gave the total H content at a micrometric scale in the bulk of hydrous geologic samples. However, it was more difficult to characterize nominally anhydrous phases. Recent efforts allowed us to significantly improve the different steps of the ERDA analysis, from the sample preparation to the determination of the uncertainties of the resulting H concentration. A large series of very different geological samples has been measured: volcanic glasses and glassy inclusions, synthetic and natural nominally anhydrous minerals. Our new sample preparation protocol limited the thickness of the surface layer of H-pollution, leading to an easier differentiation of the bulk contribution. Simultaneous PIXE and RBS measurements allow the precise location of the interesting areas and also give information on the chemical characterization of the investigated samples, with respect to the major and minor elements. The processing of the list-mode acquisition files is made using the RISMIN software, allowing among other interesting features to check the absence of water loss under the beam. We will present the results of the H-content measurements and show the good agreement between our present results and those obtained by Fourier transform infrared spectroscopy (FTIR) for the same set of samples. The detection limit was measured on a dehydrated natural San Carlos olivine ((Mg,Fe)2SiO4) equal to 130 wt ppm H2O (15 wt ppm H

    Full Text Available Soybean (Glycine max L. Merill tops the world production of oil seeds. Mutation breeding is the most useful and vitaltechnology for soybean. Selection of effective and efficient mutagens are very essential to recover high frequency ofdesirable mutants. The seed material of vegetable soybean cultivars viz., Himso 1563 and TS 82 were used for study.Gamma rays and EMS are the two mutagens selected for mutagenesis. Mutated population had manifested a reducedexpression than the untreated population for all biometrical traits. Reduction in phenotypic expression is linear with thedose or concentration of the mutagens in the M1 generation. Higher the dose or concentration more reduction in theexpressivity of the traits. Viable mutants were observed in the M2 generation. Induced mutations delivered fairly goodamount of genotypic coefficient of variation, the heritability and GA as per cent of mean with respect to all thebiometrical observations. High protein content (Himso 1563-37.73 and TS 82-39.49 percent and low fibre content(Himso 1563 - 7.27 and TS 82-10.55 percent mutants identified in M2 generation.

    With the escalating persuasion of economic and nutritional importance of rice grain protein and nutritional components of rice bran (RB), NIRS can be an effective tool for high throughput screening in rice breeding programme. Optimization of NIRS is prerequisite for accurate prediction of grain quality parameters. In the present study, 173 brown rice (BR) and 86 RB samples with a wide range of values were used to compare the calibration models generated by different chemometrics for grain protein (GPC) and amylose content (AC) of BR and proximate compositions (protein, crude oil, moisture, ash and fiber content) of RB. Various modified partial least square (mPLSs) models corresponding with the best mathematical treatments were identified for all components. Another set of 29 genotypes derived from the breeding programme were employed for the external validation of these calibration models. High accuracy of all these calibration and prediction models was ensured through pair t-test and correlation regression analysis between reference and predicted values. PMID:26258697

  20. Development of India-specific RAFM steel through optimization of tungsten and tantalum contents for better combination of impact, tensile, low cycle fatigue and creep properties

    International Nuclear Information System (INIS)

    Effects of tungsten and tantalum contents on impact, tensile, low cycle fatigue and creep properties of Reduced Activation Ferritic–Martensitic (RAFM) steel were studied to develop India-specific RAFM steel. Four heats of the steel have been melted with tungsten and tantalum contents in the ranges 1–2 wt.% and 0.06–0.14 wt.% respectively. Increase in tungsten content increased the ductile-to-brittle transition temperature (DBTT), low cycle fatigue and creep strength of the steel, whereas the tensile strength was not changed significantly. Increase in tantalum content increased the DBTT and low cycle fatigue strength of the steel whereas the tensile and creep strength decreased. Detailed TEM investigations revealed enhanced microstructural stability of the steel against creep exposure on tungsten addition. The RAFM steel having 1.4 wt.% tungsten with 0.06 wt.% tantalum was found to possess optimum combination of impact, tensile, low cycle fatigue and creep properties and is considered for Indian-specific RAFM steel

    Full Text Available Aquaponic is the combined culture of fish and plants. This experiment was arranged as a factorial in the framework of completely randomized design with two factors of growing system (aquaponics and hydroponics and plant species (Mentha piperita and Mentha sativa with 3 replications. The results showed that most growth factors of the two species were higher in hydroponics compared to aquaponics. Aerial parts and root fresh and dry mass, leaf area and number of nodes were higher in hydroponics compared to aquaponic culture. SPAD index was influenced by the culture system and its value was higher in hydroponic system. Essential oil content of M. sativa was higher in hydroponics and of Mentha piperita was higher in aquaponics. Lower amount of Mn and Mg in Mentha sativa shoots and N, P, Mg and Mn in Mentha piperita was the probable reason for growth reduction of plants in aquaponics as compared to hydroponics.

The results showed IAA concentration in the mesocarp of Okubo' peach was higher than wild peach at early development stage. The contents of IAA had similar trend in endocarp, but IAA contents were higher in the endocarp of wild peach than in the one of cultivated peach. The IAA contents of normal 'Ruiguang 5' peach was significantly different with spilt-pit peaches. The contents of IAA in spilt-pit endocarp was obviously higher than that of normal fruit at 77 days after full blossom, which showed that spilt-pit caused the exception of IAA contens. The results demonstrated that the normal development, maturation and the split-pit of peach fruit were related with auxin.

    Great advances in tissue androgen analysis using liquid chromatography-tandem mass spectrometry (LC-MS/MS) have made it possible to evaluate the tissue androgen content from a single needle prostate biopsy specimen. In this study, we investigated if pre-treatment androgen content in prostate biopsy specimens could predict their response to primary androgen deprivation therapy (ADT) and future castration-resistant prostate cancer (CRPC). One-hundred and sixty-five prostate cancer patients who received primary ADT were enrolled. They had received multiple core prostate needle biopsy at diagnosis, and an additional one needle biopsy specimen was obtained for tissue androgen determination using LC-MS/MS. The patients' prostate specific antigen (PSA) values were periodically followed during the treatment and patients were determined to have CRPC when their PSA value increased continuously to 25% above the nadir and a 2.0 ng/mL increase. A significant correlation was found between PSA value decline velocity (PSA half-time) after ADT and pre-ADT tissue androgen content. Twenty-three patients were determined to have CRPC. These CRPC patients had a significantly high concentration of tissue T (p development. By using the two statistically significant variables, the relative risk of CRPC development could be calculated. The results of this study suggest that the evaluation of prostate androgen content in a single needle biopsy specimen may be useful to predict future CRPC development after primary ADT. Further studies are required for the clinical application of T/DHT ratio evaluation. PMID:23444052

  6. Organic Tank Safety Project: development of a method to measure the equilibrium water content of Hanford organic tank wastes and demonstration of method on actual waste

    International Nuclear Information System (INIS)

    Some of Hanford's underground waste storage tanks contain Organic- bearing high level wastes that are high priority safety issues because of potentially hazardous chemical reactions of organics with inorganic oxidants in these wastes such as nitrates and nitrites. To ensure continued safe storage of these wastes, Westinghouse Hanford Company has placed affected tanks on the Organic Watch List and manages them under special rules. Because water content has been identified as the most efficient agent for preventing a propagating reaction and is an integral part of the criteria developed to ensure continued safe storage of Hanford's organic-bearing radioactive tank wastes, as part of the Organic Tank Safety Program the Pacific Northwest National Laboratory developed and demonstrated a simple and easily implemented procedure to determine the equilibrium water content of these potentially reactive wastes exposed to the range of water vapor pressures that might be experienced during the wastes' future storage. This work focused on the equilibrium water content and did not investigate the various factors such as at sign ventilation, tank surface area, and waste porosity that control the rate that the waste would come into equilibrium, with either the average Hanford water partial pressure 5.5 torr or other possible water partial pressures

    External content sources such as MEDLINE(®), National Institutes of Health (NIH) grants and conference websites provide access to the latest breaking biomedical information, which can inform pharmaceutical and biotechnology company pipeline decisions. The value of the sites for industry, however, is limited by the use of the public internet, the limited synonyms, the rarity of batch searching capability and the disconnected nature of the sites. Fortunately, many sites now offer their content for download and we have developed an automated internal workflow that uses text mining and tailored ontologies for programmatic search and knowledge extraction. We believe such an efficient and secure approach provides a competitive advantage to companies needing access to the latest information for a range of use cases and complements manually curated commercial sources.

    Full Text Available Agricultural practices determine the level of food production and, to great extent, the state of the global environment. During the last decades, the indiscriminate recourse to fertilizers as well as the nitrogen losses from land application have been recognized as serious issues of modern agriculture, globally contributing to nitrate pollution. The development of a reliable Near-Infra-Red Spectroscopy (NIRS-based method, for the simultaneous monitoring of nitrogen and chlorophyll in fresh apple (Malus domestica leaves, was investigated on a set of 133 samples, with the aim of estimating the nutritional and physiological status of trees, in real time, cheaply and non-destructively. By means of a FT (Fourier Transform-NIR instrument, Partial Least Squares (PLS regression models were developed, spanning a concentration range of 0.577%–0.817% for the total Kjeldahl nitrogen (TKN content (R2 = 0.983; SEC = 0.012; SEP = 0.028, and of 1.534–2.372 mg/g for the total chlorophyll content (R2 = 0.941; SEC = 0.132; SEP = 0.162. Chlorophyll-a and chlorophyll-b contents were also evaluated (R2 = 0.913; SEC = 0.076; SEP = 0.101 and R2 = 0.899; SEC = 0.059; SEP = 0.101, respectively. All calibration models were validated by means of 47 independent samples. The NIR approach allows a rapid evaluation of the nitrogen and chlorophyll contents, and may represent a useful tool for determining nutritional and physiological status of plants, in order to allow a correction of nutrition programs during the season.

    The current study was carried out to investigate the effects of breeder age on egg composition, changes of embryo, yolk sac, and yolk minerals during incubation and hatchability in Pekin ducks. A total of 495 freshly laid eggs were obtained from the same flock of Pekin ducks, aged 28, 34, and 40 wk, and were reared in accordance with the management guide of the duck breeders (Star 53-Grimaud Freres). At each breeder age, egg measurements were made on a random subsample of unincubated eggs. Embryo and yolk sac measurements were made on embryonic day (E) 12, E16, E20, and E25. On d 28 of incubation, the healthy ducklings were removed and sex of chicks was determined. All chicks were weighed and hatching results were determined. Egg weight and yolk percentages increased; however, albumen percentages, shell thickness, and yolk index decreased as the flock aged. Shell percentages, shell breaking strength, albumen index, and haugh units were not affected by breeder age. Also, breeder age affected the Mg, P, K, Ca, Cu, and Zn levels in the yolk, except for Na level on day of setting, and breeder age affected the mineral consumed by embryo during incubation. However, on E25, the levels of examined minerals, except for P level in the yolk sac, were not statistically different in duck breeder age groups. Relative yolk sac and embryo weights of eggs obtained from different breeder ages varied from E16 to E25; however, embryo length was different in breeder age groups from E12 to E20. Hatching weight was affected by breeder age and sex. Hatching results were not different among breeder age groups. This study indicates that breeder age is important for some egg characteristics, relative yolk sac weight, some contents of minerals in the yolk, embryonic growth during incubation, and duckling weight.

    This study investigated the ability of near-infrared spectroscopy (NIRS) to predict acrylamide content in French-fried potato. Potato flour spiked with acrylamide (50-8000 μg/kg) was used to determine if acrylamide could be accurately predicted in a potato matrix. French fries produced with various pretreatments and cook times (n = 84) and obtained from quick-service restaurants (n = 64) were used for model development and validation. Acrylamide was quantified using gas chromatography-mass spectrometry, and reflectance spectra (400-2500 nm) of each freeze-dried sample were captured on a Foss XDS Rapid Content Analyzer-NIR spectrometer. Partial least-squares (PLS) discriminant analysis and PLS regression modeling demonstrated that NIRS could accurately detect acrylamide content as low as 50 μg/kg in the model potato matrix. Prediction errors of 135 μg/kg (R(2) = 0.98) and 255 μg/kg (R(2) = 0.93) were achieved with the best PLS models for acrylamide prediction in Russet Norkotah French-fried potato and multiple samples of unknown varieties, respectively. The findings indicate that NIRS can be used as a screening tool in potato breeding and potato processing research to reduce acrylamide in the food supply. PMID:26806330

    2009-01-01

    The use of Self-Interrogation Neutron Resonance Densitometry (SINRD) to measure the {sup 235}U and {sup 239}Pu content in a PWR spent fuel assembly was investigated via Monte Carlo N-Particle eXtended transport code (MCNPX) simulations. The sensitivity of SINRD is based on using the same fissile materials in the fission chambers as are present in the fuel because the effect of resonance absorption lines in the transmitted flux is amplified by the corresponding (n, f) reaction peaks in fission chamber. These simulations utilize the {sup 244}Cm spontaneous fission neutrons to self-interrogate the fuel pins. The amount of resonance absorption of these neutrons in the fuel can be measured using {sup 235}U and {sup 239}Pu fission chambers placed adjacent to the assembly. We used ratios of different fission chambers to reduce the sensitivity of the measurements to extraneous material present in fuel. The development of SINRD to measure the fissile content in spent fuel is of great importance to the improvement of nuclear safeguards and material accountability. Future work includes the use of this technique to measure the fissile content in FBR spent fuel and heavy metal product from reprocessing methods.

    From 2009-2011, with support from the National Science Foundation (ITEST, DRL-0929846) and Science Foundation Arizona (MSAG-0412-09), educators, geologists and geographers at Northern Arizona University (NAU) partnered to offer professional development for interdisciplinary teams of secondary and middle school teachers with a focus on project-based instruction (PBI) using geospatial technologies (GST). While participating in professional development teachers received support and were held accountable to NAU staff. They implemented activities and pedagogical strategies presented, increased knowledge, skills, and confidence teaching with project-based instruction integrating GST, and their students demonstrated learning gains. Changes in student understanding are only observed when teachers continue to implement change, so the question remained: did these changes in practice sustain after official project support ended? In order to determine what, if anything, teachers sustained from the professional development and the factors that promoted or hindered sustained use of teaching with GST and PBI, data were collected one to two years following the professional development. Research questions included a) what pedagogical practices did teachers sustain following the professional learning experiences? and b) what contexts were present in schools that supported or limited the use of geospatial technologies as a teaching and learning tool? Findings from this study indicate that teachers fall into three categories of sustaining implementation - reformed implementers, mechanical implementers and non-implementers. School context was less of a factor in level of implementation than teachers' beliefs and philosophy of teaching and teachers' understanding of technology integration (teaching with technology vs. teaching technology). Case studies of teacher experiences will be presented along with implications for future professional development.

    2009-12-01

    The scientific complexities of global climate change, with wide-ranging economic and social significance, create an intellectual challenge that mandates greater public understanding of climate change research and the concurrent ability to make informed decisions. The critical need for an engaged, science literate public has been repeatedly emphasized by multi-disciplinary entities like the Intergovernmental Panel on Climate Change (IPCC), the National Academies (Rising Above the Gathering Storm report), and the interagency group responsible for the recently updated Climate Literacy: The Essential Principles of Climate Science. There is a clear need for an American public that is climate literate and for K-12 teachers confident in teaching relevant science content. A key goal in the creation of a climate literate society is to enhance teachers’ knowledge of global climate change through a national, scalable, and sustainable professional development system, using compelling climate science data and resources to stimulate inquiry-based student interest in science, technology, engineering, and mathematics (STEM). This session will explore innovative e-learning technologies to address the limitations of one-time, face-to-face workshops, thereby adding significant sustainability and scalability. The resources developed will help teachers sift through the vast volume of global climate change information and provide research-based, high-quality science content and pedagogical information to help teachers effectively teach their students about the complex issues surrounding global climate change. The Learning Center is NSTA's e-professional development portal to help the nations teachers and informal educators learn about the scientific complexities of global climate change through research-based techniques and is proven to significantly improve teacher science content knowledge.

    2009-01-01

    Full Text Available Problem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse crops and small-scale farming systems in Malaysia will present new challenges. Describing within-field variability in typical Malaysian production settings is a fundamental first step toward determining the size of management zones and the inter-relationships between limiting factors, for establishment of site-specific management strategies. Results: Measurements of rice SPAD readings and nitrogen content were obtained in a Malaysian rice paddy field. SPAD reading data was manually collected on 80DAT and measured using a Minolta SPAD 502. Leaf samples were collected at 60 points at the same time to compare results from sampling with SPAD reading values. Samples nitrogen content was analyzed in a laboratory. Analysis of variance, variogram and kriging were conducted to determine the variability of the measured parameters and also their relationship. SPAD reading and nitrogen content maps were created on the interpretation of the data was investigated. Conclusion/Recommendations: Finally the research indicated that SPAD readings are closely related to leaf N content which means the potential for technology of precision farming to understand and control variation in Malaysian production fields and also SPAD chlorophyll meter ability to monitor the N status of rice and recommend the amount of N fertilization. Additional research is needed to confirm the results with data from other fields and crops.

    Cytosolic lipids participate in the growth, development, and overall health of mammalian oocytes including many roles in cellular homeostasis. Significant emphasis has been placed on the study of lipids as a dynamic organelle, which in turn requires the development of tools and techniques to quantitate and compare how lipid content relates to cellular structure, function, and normalcy. Objectives of this study were to determine if nonlinear vibrational microscopy (e.g., coherent anti-Stokes Raman scattering or CARS microscopy) could be used for live-cell imaging to quantify and compare lipid content in mammalian oocytes during development and in relation to body composition; and compare its efficacy to methods involving cellular fixation and staining protocols. Results of this study demonstrate that CARS is able to identify lipids in live mammalian oocytes, and there exists quantifiable and consistent differences in percent lipid composition across ooctyes of different species, developmental stages, and in relation to body composition. Such a method of live-cell lipid quantification has (i) experimental power in basic cell biology, (ii) practical utility for identifying developmental predictive biomarkers while advancing biology-based oocyte/embryo selection, and (iii) ability to yield rationally supporting technology for decision-making in rodents, domestic species, and human assisted reproduction and/or fertility preservation.

    To manage negative energy balance and ketosis in dairy farms, rapid and cost-effective detection is needed. Among the milk biomarkers that could be useful for this purpose, acetone and β-hydroxybutyrate (BHB) have been proved as molecules of interest regarding ketosis and citrate was recently identified as an early indicator of negative energy balance. Because Fourier transform mid-infrared spectrometry can provide rapid and cost-effective predictions of milk composition, the objective of this study was to evaluate the ability of this technology to predict these biomarkers in milk. Milk samples were collected in commercial and experimental farms in Luxembourg, France, and Germany. Acetone, BHB, and citrate contents were determined by flow injection analysis. Milk mid-infrared spectra were recorded and standardized for all samples. After edits, a total of 548 samples were used in the calibration and validation data sets for acetone, 558 for BHB, and 506 for citrate. Acetone content ranged from 0.020 to 3.355mmol/L with an average of 0.103mmol/L; BHB content ranged from 0.045 to 1.596mmol/L with an average of 0.215mmol/L; and citrate content ranged from 3.88 to 16.12mmol/L with an average of 9.04mmol/L. Acetone and BHB contents were log-transformed and a part of the samples with low values was randomly excluded to approach a normal distribution. The 3 edited data sets were then randomly divided into a calibration data set (3/4 of the samples) and a validation data set (1/4 of the samples). Prediction equations were developed using partial least square regression. The coefficient of determination (R(2)) of cross-validation was 0.73 for acetone, 0.71 for BHB, and 0.90 for citrate with root mean square error of 0.248, 0.109, and 0.70mmol/L, respectively. Finally, the external validation was performed and R(2) obtained were 0.67 for acetone, 0.63 for BHB, and 0.86 for citrate, with respective root mean square error of validation of 0.196, 0.083, and 0.76mmol/L.

    How pre-service teachers (PST) develop pedagogical content knowledge (PCK) during science teacher education is an open research question. Our teacher education module, theoretically based on PCK, specifically combines biology PSTs' education with high school students' biology education and includes an innovative role change approach. Altogether, 41 PSTs each participated in three subsequent module days with students (N = 823) from 50 classes. The module's content dealt with the syllabus topic Genetic Fingerprinting. During participation, the PSTs changed their role by assuming a student's role on the first day, a tutor's role on the second day, and a teacher's role on the third day. By quasi-experimentally administering pre- and delayed posttests, we qualitatively monitored, then content-analytically categorized, and finally quantitatively analyzed three specific PCK components. In contrast to a control group (which did not participate in the module), our treatment preferentially changed the PSTs' orientations toward teaching biology to a more student-centered orientation (both intra- and inter-group differences with medium effect sizes). Additionally, the PSTs who participated in the three modules days differed before and after module participation in how they addressed potential student learning difficulties and identified potential instructional strategies for avoiding these difficulties. The changes in these PCK components point to a step-by-step development of the PSTs' PCK. In this process, our participating PSTs assessed the importance of their three roles on the 3 days quite differently; most notably, we found one relationship between the teacher role and the PSTs' student-centeredness. We specifically discuss the potential and importance of our role change approach within science teacher education.

    2014-08-01

    Research supports an explicit-reflective approach to teaching about nature of science (NOS), but little is reported on teachers' journeys as they attempt to integrate NOS into everyday lessons. This participatory action research paper reports the challenges and successes encountered by an in-service teacher, Sarah, implementing NOS for the first time throughout four units of a community college biology course (genetics, molecular biology, evolution, and ecology). Through the action research cycles of planning, implementing, and reflecting, Sarah identified areas of challenge and success. This paper reports emergent themes that assisted her in successfully embedding NOS within the science content. Data include weekly lesson plans and pre/post reflective journaling before and after each lesson of this lecture/lab combination class that met twice a week. This course was taught back to back semesters, and this study is based on the results of a year-long process. Developing pedagogical content knowledge (PCK) for NOS involves coming to understand the overlaps and connections between NOS, other science subject matter, pedagogical strategies, and student learning. Sarah found that through action research she was able to grow and assimilate her understanding of NOS within the biology content she was teaching. A shift in orientation toward teaching products of science to teaching science processes was a necessary shift for NOS pedagogical success. This process enabled Sarah's development of PCK for NOS. As a practical example of putting research-based instructional recommendations into practice, this study may be very useful for other teachers who are learning to teach NOS.

    Sweet potato (Ipomoea batatas L.) is a nutritious food crop and, based on the high starch content of its storage root, a potential bioethanol feedstock. Enhancing the nutritional value and starch quantity of storage roots are important goals of sweet potato breeding programs aimed at developing improved varieties for direct consumption, processing, and industrial uses. However, developing improved lines of sweet potato is challenging due to the genetic complexity of this plant and the lack of genome information. Short sequence repeat (SSR) markers are powerful molecular tools for tracking important loci in crops and for molecular-based breeding strategies; however, few SSR markers and marker-trait associations have hitherto been identified in sweet potato. In this study, we identified 1824 SSRs by using a de novo assembly of publicly available ESTs and mRNAs in sweet potato, and designed 1476 primer pairs based on SSR-containing sequences. We mapped 214 pairs of primers in a natural population comprised of 239 germplasms, and identified 1278 alleles with an average of 5.972 alleles per locus and a major allele frequency of 0.7702. Population structure analysis revealed two subpopulations in this panel of germplasms, and phenotypic characterization demonstrated that this panel is suitable for association mapping of starch-related traits. We identified 32, 16, and 17 SSR markers associated with starch content, β-carotene content, and starch composition in the storage root, respectively, using association analysis and further evaluation of a subset of sweet potato genotypes with various characteristics. The SSR markers identified here can be used to select varieties with desired traits and to investigate the genetic mechanism underlying starch and carotenoid formation in the starchy roots of sweet potato.

  14. The application of systematic analysis to the development for maintenance staffs training contents in Nuclear Power Station

    International Nuclear Information System (INIS)

    To survive the tide of electric power industry deregulation, actions for streamlining our operations must be compatible with safe of plant operation. With regard to the human resource issue, retirement of first line engineers who developed their practical technical skills through the process of experiencing numerous problems or plant construction can raise concerns regarding a decline in our engineering abilities. Under these circumstances, to prepare sophisticated maintenance engineers, training programs must be optimized by considering the most effective and efficient method and material. Despite the IAEA's SAT (Systematic Approach to Training) method being widely applied to train nuclear power plants operators, there are few reports that it is applied to maintenance engineers. This paper will discuss our attempt to introduce more effective and efficient training for maintenance engineers, as well as refer to the SAT method to analyze the education program as a whole.

    Full Text Available Teaching in recent days class room environment is more difficult than ever in the history of academia. In recent times world there are big number of distractions invade the concentration of a student in the classroom. With the advancement in technological gadgets for example laptops, notebooks, smart phones etc. major addition is of distraction. It is more difficult and challenging to maintain the interest and concentration of students in virtual environment where instructor/teacher is not physically present in the classroom which is typically a model of distance education. The lack of concentration level directly influences the quality of education. In the present studies, we have proposed a model and develop a software to use information and communication technology to increase the concentration level of the students studying in distance mode which will directly improve the quality of education imparted in distance mode.

    Palmitoyl peptides are anti-aging agents widely used in cosmetics. This article describes the development of a LC-MS/MS analytical procedure that allows, after a liquid-liquid extraction procedure, their unambiguous detection in cosmetic formulation. MS/MS detection is shown to be specific regarding placebo formulations. Limits of quantification, linearity, accuracy and precision of the method were estimated. The results presented show that palmitoyl peptides can be thus reliably assayed. The palmitoylated pentapeptide palmitoyl-lysyl-threonyl-threonyl-lysyl-serine (pal-KTTKS) was assayed in anti-wrinkle creams using palmitoyl-glycyl-histidyl-lysine (pal-GHK) as internal standard. From the results obtained, the influence of the formulation on pal-KTTKS availability is evidenced. PMID:19393372

  18. The influence of sand content on swelling pressures and structure developed in statically compacted Na-bentonite

    International Nuclear Information System (INIS)

    A laboratory investigation of the vertical and lateral swelling pressures developed in statically compacted, air-dry specimens of sodium (Na)-bentonite:silica sand mixtures as they are saturated in confined conditions with double-distilled, deionized water is described. The results are interpreted with the aid of observations of the compacted soil structures made in a scanning electron microscope. It is shown that the sand acts as an inert filler material and vertical swelling pressures are controlled by a parameter termed the effective clay dry density (qsub(c)). A limiting value of qsub(c) exists below which vertical and lateral swelling pressures do not differ and are theoretically predictable. Above this value, vertical pressures exceed lateral ones. This is related to a change from an isotropic to an anisotropic soil fabric as qsub(c) is increased above the limiting value

    Coal combustion residues (CCRs) are documented to negatively impact oral morphology, growth, and development in larval amphibians. It is currently unclear what physiological mechanisms may mediate these effects. Corticosterone, a glucocorticoid hormone, is a likely mediator because when administered exogenously it, like CCRs, also negatively influences oral morphology, growth, and development in larval amphibians. In an attempt to identify if corticosterone mediates these effects, we raised larval Southern Leopard Frogs, Rana sphenocephala, on either sand or CCR substrate and documented effects of sediment type on whole body corticosterone, oral morphology, and time to and mass at key metamorphic stages. Coal combustion residue treated tadpoles contained significantly more corticosterone than controls throughout metamorphosis. However, significantly more oral abnormalities occurred early in metamorphosis when differences in corticosterone levels between treatments were minimal. Overall, CCR-treated tadpoles took significantly more time to transition between key stages and gained less mass between stages than controls, but these differences between treatments decreased during later stages when corticosterone differences between treatments were greatest. Our results suggest endogenous increase in corticosterone content and its influence on oral morphology, growth and development is more complex than previously thought.

    Directory of Open Access Journals (Sweden)

    Hee-Jong Woo

    Full Text Available Development of marker-free transgenic plants is a technical alternative for avoiding concerns about the safety of selectable marker genes used in genetically modified (GM crops. Here, we describe the construction of a spontaneous self-excision binary vector using an oxidative stress-inducible modified FLP/FRT system and its successful application to produce marker-free transgenic rice plants with enhanced seed tocopherol content. To generate selectable marker-free transgenic rice plants, we constructed a binary vector using the hpt selectable marker gene and the rice codon-optimized FLP (mFLP gene under the control of an oxidative stress-inducible promoter between two FRT sites, along with multiple cloning sites for convenient cloning of genes of interest. Using this pCMF binary vector with the NtTC gene, marker-free T1 transgenic rice plants expressing NtTC were produced by Agrobacterium-mediated stable transformation using hygromycin as a selective agent, followed by segregation of selectable marker genes. Furthermore, α-, γ-, and total tocopherol levels were significantly increased in seeds of the marker-free transgenic TC line compared with those of wild-type plants. Thus, this spontaneous auto-excision system, incorporating an oxidative stress-inducible mFLP/FRT system to eliminate the selectable marker gene, can be easily adopted and used to efficiently generate marker-free transgenic rice plants. Moreover, nutritional enhancement of rice seeds through elevation of tocopherol content coupled with this marker-free strategy may improve human health and public acceptance of GM rice.

    Back pain is a complex phenomenon that goes beyond a simple medical diagnosis. The aetiology and chronification of back pain can be best described as an interaction between biological, psychological, and social processes. However, to date, multimodal prevention and intervention programs for back pain that target all three aetiological factors have demonstrated limited effectiveness. This lack of supportive evidence for multimodal programmes in the treatment of back pain could be due to the fact that few programs are suitable for long-term and unsupervised use in everyday life. Moreover, in combining the elements from various therapies, little attention has been paid to the mechanisms underlying the synergistic effects of the separate components. In this contribution, we will describe the development of a new multimodal intervention for back pain that set out to address these limitations. To this end, the biological elements of neuromuscular adaptation is supplemented with cognitive behavioral and psychophysiological techniques in an intervention that can be followed at home as well as in clinics, and that is suitable for all grades of pain. The efficacy of this intervention will be tested in a multicentric randomized controlled longitudinal trial (n = 714) at five time points over a period of 6 months. Here we will describe the development and the content of this new intervention. PMID:26337688

  12. A Large Repetitive RTX-Like Protein Mediates Water-Soaked Lesion Development, Leakage of Plant Cell Content and Host Colonization in the Pantoea stewartii subsp. stewartii Pathosystem.

    Pantoea stewartii subsp. stewartii is the etiological agent of Stewart's wilt and is a serious bacterial pathogen affecting sweet corn. During the leaf blight phase, P. stewartii colonizes the leaf apoplast and causes a characteristic water-soaked lesion. The Hrp type III secretion system has been implicated in the water-soaking phenotype, and the goal of this study was to investigate other potential factors that contribute to the plant cellular disruption associated with these lesions. The P. stewartii genome contains a gene encoding a large repetitive RTX toxin, designated rtx2. RTX toxins comprise a large family of pore-forming proteins, which are widely distributed among gram-negative bacteria. These cytotoxins usually lyse their target host cells and cause significant tissue damage as a consequence. We hypothesized that this RTX-like toxin plays a role in the water-soaking phase of infection due to its predicted cytolytic properties. Based on the data reported here, we conclude that RTX2 contributes significantly to the development of water-soaked lesions and leakage of plant cellular contents and is an important pathogenicity factor for P. stewartii.

    Patients with castration-resistant prostate cancer (CRPC) can be treated with abiraterone, a potent inhibitor of androgen synthesis, or enzalutamide, a second-generation androgen receptor (AR) antagonist, both targeting AR signaling. However, most patients relapse after several months of therapy and a majority of patients with relapsed CRPC tumors express the AR target gene prostate-specific antigen (PSA), suggesting that AR signaling is reactivated and can be targeted again to inhibit the relapsed tumors. Novel small molecules capable of inhibiting AR function may lead to urgently needed therapies for patients resistant to abiraterone, enzalutamide, and/or other previously approved antiandrogen therapies. Here, we describe a high-throughput high-content screening (HCS) campaign to identify small-molecule inhibitors of AR nuclear localization in the C4-2 CRPC cell line stably transfected with GFP-AR-GFP (2GFP-AR). The implementation of this HCS assay to screen a National Institutes of Health library of 219,055 compounds led to the discovery of 3 small molecules capable of inhibiting AR nuclear localization and function in C4-2 cells, demonstrating the feasibility of using this cell-based phenotypic assay to identify small molecules targeting the subcellular localization of AR. Furthermore, the three hit compounds provide opportunities to develop novel AR drugs with potential for therapeutic intervention in CRPC patients who have relapsed after treatment with antiandrogens, such as abiraterone and/or enzalutamide.

    We have previously reported that mice with neuron-specific LPL deficiency (NEXLPL-/-) become obese by 16weeks of age on chow. Moreover, these mice had reduced uptake of triglyceride (TG)-rich lipoprotein-derived fatty acids and lower levels of n-3 long chain polyunsaturated fatty acids (n-3 PUFAs) in the hypothalamus. Here, we asked whether increased dietary fat content or altered dietary composition could modulate obesity development in NEXLPL-/- mice. Male NEXLPL-/- mice and littermate controls (WT) were randomly assigned one of three synthetic diets; a high carbohydrate diet (HC, 10% fat), a high-fat diet (HF, 45% fat), or a HC diet supplemented with n-3 PUFAs (HCn-3, 10% fat, Lovaza, GSK®). After 42weeks of HC feeding, body weight and fat mass were increased in the NEXLPL-/- mice compared to WT. WT mice fed a HF diet displayed typical diet-induced obesity, but weight gain was only marginal in HF-fed NEXLPL-/- mice, with no significant difference in body composition. Dietary n-3 PUFA supplementation did not prevent obesity in NEXLPL-/- mice, but was associated with differential modifications in hypothalamic gene expression and PUFA concentration compared to WT mice. Our findings suggest that neuronal LPL is involved in the regulation of body weight and composition in response to either the change in quantity (HF feeding) or quality (n-3 PUFA-enriched) of dietary fat. The precise role of LPL in lipid sensing in the brain requires further investigation. PMID:27282869

    To investigate the regulation of glycogen metabolism at the mRNA level in Crassostrea angulata, we cloned and characterized glycogen synthase and glycogen synthase kinase 3β cDNAs (Ca-GYS and Ca-GSK3β, respectively), which encode the primary enzymes involved in glycogen storage. We examined their expression profiles in different tissues and during different reproductive stages. The full-length cDNA of GYS was 4771 bp in length with a 2023 bp open reading frame (ORF), predicted to encode a protein of 674 aa. The full-length GSK3β cDNA was 2333 bp long, with an ORF of 1242 bp. High expression levels of both genes were observed in the gonad and the adductor muscle, as compared to the mantle, gill, or visceral mass, which correlates well with the ability to store glucose. The regulation of both genes was correlated with glycogen content via qPCR and in situ hybridization and was dependent upon the stage of the reproductive cycle (initiation stage, maturation stage, ripeness stage). Thus, it appears that the expression of Ca-GYS and Ca-GSK3β is driven by the reproductive cycle of the oyster, reflecting the central role played by glycogen in energy storage and gametogenic development in C. angulata. We suggest that Ca-GYS and Ca-GSK3β can be used as useful molecular markers for identifying the stages of glycogen metabolism and reproduction in C. angulata. PMID:24035883

    Ginsenoside Re (GRe) is a major active component of the Chinese medicinal herb ginseng, Panax ginseng . A sensitive and specific monoclonal antibody (mAb), designated as mAb3D6, was generated with a GRe-bovine serum albumin conjugate as an immunogen. Microcantilever immunosensors (MCS), one modified with thiolated anti-GRe antibody and one modified with thiolated goat antimouse immunoglobulin G (IgG), were developed to detect the content of ginsenoside. The MCS immobilized with thiolated goat antimouse IgG had a better sensitivity than the MCS modified with thiolated anti-GRe antibody. The advantage of a secondary antibody thio-functionalized MCS was verified with the anti-paclitaxel mAb. An indirect competitive enzyme-linked immunosorbent assay (icELISA) was also established with mAb3D6. The concentration of analyte producing 50% inhibition and the working range of icELISA were 1.20 and 0.15-16.1 ng/mL, respectively. The icELISA had a cross-reactivity of 89% with ginsenoside Rg1 and less than 3% with other ginsenosides. The icELISA and MCS with thiolated secondary antibody were applied for the determination of GRe in ginseng samples, and the results agreed well with those determined by high-performance liquid chromatography.

    Full Text Available Problem statement: In order to meet the ever increasing demand of medicinal plants, for the indigenous systems of medicine as well as for the pharmaceutical industry, some medicinal plants need to be cultivated commercially and moldavian balm (Dracocephalum moldavica is one of them. Approach: To determine the effects of zeolite and water stress on aforementioned plants phisiomorphological characteristics, an experiment was conducted with applying four zeolite levels and three water discharge levels during plant growth. Some growth and development parameters were measured. Results: Summarized that, zeolite did not have any significant effect on plant height and number of internodes but had, on the other traits. There were not a significant effect of water discharge on plant height, number of flowers and number of internodes but its effect on the flowering time and essential oil content was significant. Moreover, there was not an interaction between zeolite and water stress on number of flowers and number of internodes but this interaction was significant on the other parameters. Conclusions/Recommendations: Finally, 2 g zeolite with 50% water losses was recommended to obtain higher essential oil. Additional researches are needed to confirm the results for data from other fields and crops.

    Lubricating oils are crucial in the operation of automotive engines because they both reduce friction between moving parts and protect against corrosion. However, the performance of lubricant oil may be affected by contaminants, such as gasoline, diesel, ethanol, water and ethylene glycol. Although there are many standard methods and studies related to the quantification of contaminants in lubricant oil, such as gasoline and diesel oil, to the best of our knowledge, no methods have been reported for the quantification of ethanol in used Otto cycle engine lubrication oils. Therefore, this work aimed at the development and validation of a routine method based on partial least-squares multivariate analysis combined with attenuated total reflectance in the mid-infrared region to quantify ethanol content in used lubrication oil. The method was validated based on its figures of merit (using the net analyte signal) as follows: limit of detection (0.049%), limit of quantification (0.16%), accuracy (root mean square error of prediction=0.089% w/w), repeatability (0.05% w/w), fit (R(2)=0.9997), mean selectivity (0.047), sensitivity (0.011), inverse analytical sensitivity (0.016% w/w(-1)) and signal-to-noise ratio (max: 812.4 and min: 200.9). The results show that the proposed method can be routinely implemented for the quality control of lubricant oils. PMID:23618159

    Despite their positive effect in reducing pest populations, exotic generalist predators sometimes become invasive and contribute to the displacement of indigenous species in the same trophic level. Although laboratory experiments have linked intraguild predation (IGP) to these interactions, field evidence and quantification of IGP are still lacking for most systems. The recent establishment of the exotic Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) in Italy raises concern about the detrimental effect that the ladybird could have on native coccinellids. Here we assessed, under laboratory conditions, the acceptability and suitability of eggs of 2 native ladybirds, Adalia bipunctata L. and Oenopia conglobata (L.), as prey items for H. axyridis larvae. Then we developed primers for molecular gut-content analysis to detect predation by H. axyridis on the 2 ladybirds and on the aphid Eucallipterus tiliae L. Species-specific 16S primers were developed for the 3 species and laboratory feeding trials were conducted to quantify the rate of prey DNA breakdown in the gut of H. axyridis. Moreover, to field evaluate primers, H. axyridis 4th instars (n = 132) were systematically collected from linden trees in northern Italy and screened for the presence of prey DNA. Seventy-three percent and 7% of field collected H. axyridis were positive for aphid and coccinellid DNA, respectively. Predation upon aphid and A. bipunctata was lower than predicted if density dependent consumption was expected, while predation upon O. conglobata was significantly higher. Here, we provided the first evidence of IGP among feral populations of H. axyridis and indigenous ladybird beetles, occurring in Italy. PMID:25164698

  20. Development and validation of an anion-exchange HPLC method for the determination of fluoride content and radiochemical purity in [18F]NaF

    International Nuclear Information System (INIS)

    18F-labeled sodium fluoride ([18F]NaF) is a useful bone imaging agent that has been demonstrated to be significantly more accurate than 99mTc-labeled methylene diphosphonate for the detection of both sclerotic and lytic lesions in various malignancies. A reliable anion-exchange HPLC method equipped with suppressed conductivity and radioactive detectors has been developed in order to analyze the content of NaF and radiochemical purity in [18F]NaF radiopharmaceuticals. The method described for fluoride analysis uses an isocratic elution of NaF in a Hamilton anion-exchange column using a mobile phase that consists of 7.5 mM sodium carbonate and 0.018 mM potassium thiocyanate. The flow rate was 1.0 ml/min. The method was validated in accordance with several parameters, including system suitability, specificity, precision, accuracy, linearity, robustness, limit of detection and limit of quantification. The results are described as follows: (1) The system suitability includes the tailing factor, theoretical plate number and resolution, which are 1.192534, 2729.6594 and 16.7415, respectively. (2) For specificity, the solvent peak and chloride ion did not interfere with the retention time of the fluoride. (3) The percentage coefficient of variation for analysis of precision, including repeatability and intermediate precision, is less than 2.0%. (4) Accuracy of method is within the range of 98%-102%. (5) The range of linearity is from 10 to 400 μg/ml, with the correlation coefficient (R2) always being above 0.9985. (6) The data of method robustness are within acceptance criteria. (7) The limit of detection and limit of quantification are 0.0678 and 0.20 μg/ml, respectively. All of the analysis results demonstrate that this method is highly sensitive, convenient, specific and suitable for quantification of NaF over a wide linear range. Therefore, the method can be successfully performed for routine analysis of fluoride content in [18F]NaF radiopharmaceuticals and reduce

    Full Text Available Today- when the influence of the alteration movement done in order to keep up with the age of the educational system is still continuing- the importance of teachers in students’ learning and achieving what is expected from the education system has been stated by the studies conducted (Hazır & Bıkmaz, 2006. Teachers own a critical role in the stage of both preparing teaching materials and using them (Stein & Smith, 1998b; Swan, 2007. When the existing curriculums –in particular, maths and geometry cirriculums- are analyzed, it can be observed that activities are the most significant teaching materials (Bozkurt, 2012. In fact, it is possible to characterize the existing curriculums as activity-based ones (Report of Workshop Examining Content of Primary School Curriculums According to Branches, 2010; Epö, 2005. Therefore, what sort of learning activities there are, what qualities they need to have, how to design and apply them are topics that must be elaborated (Uğurel et al., 2010.  At this point, our study to increase the skills of pre-service teachers during the process of developing activities was conducted with 27 pre-service teachers -19 girls 8 boys- studying in the 4th year in Mathematics Education Department at a state university in the Aegean Region. The activity designs the pre-service teachers developed considering the patterns given after a series of practice were analyzed in documents in terms of the aim of design and the form of practice. As a result of the studies, it is observed that pre-service teachers deal with the topics from the maths curriculum and these topics are of different grade levels. The result of the examination named as target component suggests that activities developed aim firstly at providing learning and this is followed by reinforcing the concepts already learned. It is stated that pre-service teachers prefer mostly small group (cooperative studies in the activities they develop.Key Words:

    2012-06-01

    Knowledge about the nature of science has been advocated as an important component of science because it provides a framework on which the students can incorporate content knowledge. However, little empirical evidence has been provided that links nature of science knowledge with content knowledge. The purpose of this mixed method study was to determine if both nature of science knowledge and content knowledge could be increased with an explicit, reflective nature of science intervention utilizing self-regulation over an implicit group. Results showed that the explicit group significantly outperformed the implicit group on both nature of science and content knowledge assessments. Students in the explicit group also demonstrated a greater use of detail in their inquiry work and reported a higher respect for evidence in making conclusions than the implicit group. Implications suggest that science educators could enhance nature of science instruction using goal setting and self-monitoring of student work during inquiry lessons.

    This paper presents a content structure for building mobile augmented reality (AR) applications in HTML5 to achieve a clean separation of the mobile AR content and the application logic for scaling as on the Web. We propose that the content structure contains the physical world as well as virtual assets for mobile AR applications as document object model (DOM) elements and that their behaviour and user interactions are controlled through DOM events by representing objects and places with a uniform resource identifier. Our content structure enables mobile AR applications to be seamlessly developed as normal HTML documents under the current Web eco-system.

    We have developed a Holographic Content Addressable Storage (HCAS) architecture. The HCAS systems consists of a DMD (Digital Micromirror Array) as the input Spatial Light Modulator (SLM), a CMOS (Complementary Metal-oxide Semiconductor) sensor as the output photodetector and a photorefractive crystal as the recording media. The HCAS system is capable of performing optical correlation of an input image/feature against massive reference data set stored in the holographic memory. Detailed system analysis will be reported in this paper.

    Responses of caryopsis germination, seedling emergence, and development of Agropyron cristatum (L.) Gaertn. (Gramineae) and Bromus inermis Leyss. (Gramineae), two dominant perennial grasses in the Otindag Sandland of China, to different sand water content (SWC; 1%, 2%, 3%, 4%, 6%, 8%, 12%,16%, and 20%) were studied comparatively. The results showed that the germination responses of the two grasses to SWC were similar (i.e. caryopses could not germinate when the SWC was below 3%; at SWC ranging from 3% to 12%, the higher the SWC, the higher the germination percentage; and at a SWC of 12%20%, germination reached similarly high percentages). At a sand burial depth of 0.5 cm, the threshold of SWC for seedling emergence was 6% forA. cristatum and 8% forB. inermis; at 12%-20% SWC, the seedling emergence of both species reached similarly high percentages. The seedling growth responses of these two species to SWC gradients were different. For A. cristatum, the biomass of seedlings increased with SWC from 6% to 12%, and decreased with SWC from 12% to 20%. For B. inermis, the biomass of seedlings always increased with SWC from 8% to 20%. The results also showed that the seedlings of both species allocated more biomass to the roots with decreases in SWC. The SWC changes from April to October in natural microhabitats of both species suggested that the SWC may play an important role in caryopsis germination,seedling emergence, and the growth characteristics of the two grasses. The responses of caryopsis germination, seedling emergence, and the growth characteristics of these two species to SWC may determine their distribution patterns in the Otindag Sandland.

    My project at KSC during my spring 2011 internship was to develop a Ruby on Rails application to manage Content Documents..A Content Document is a collection of documents and information that describes what software is installed on a Launch Control System Computer. It's important for us to make sure the tools we use everyday are secure, up-to-date, and properly licensed. Previously, keeping track of the information was done by Excel and Word files between different personnel. The goal of the new application is to be able to manage and access the Content Documents through a single database backed web application. Our LCS team will benefit greatly with this app. Admin's will be able to login securely to keep track and update the software installed on each computer in a timely manner. We also included exportability such as attaching additional documents that can be downloaded from the web application. The finished application will ease the process of managing Content Documents while streamlining the procedure. Ruby on Rails is a very powerful programming language and I am grateful to have the opportunity to build this application.

    Absorption and fluorescent cytophotometry techniques were applied to studies of RNA, glycogen and its fractions in hepatocytes of patients with hard mechanic trauma, both with and without endointoxication. For measuring RNA and glycogen contents, slides were stained by gallocyanin-chromalum or underwent fluorescent PAS-reaction, respectively. The repeated aspiration biopsy material was used for investigation of RNA and glycogen contents in dynamics. A quick increase in RNA content took place at the first stage (within the first 3 days) of traumatic illness of both the groups of patients. At the second stage of illness the hepatocyte RNA content in patients without endointoxication was seen to decrease to the initial level, whereas that in patients with endointoxication increased from the initial level by 36%. At different stages of illness the total glycogen content is changed insignificantly in the course of illness, but its labile fraction decreases to 70% of the total glycogen in patients with endointoxication. The increase of hepatocyte synthetic activity and the maintenance of the normal glycogen level may suggest a sufficient compensatory possibility of the liver, in spite of a high functional load under endointoxication.

    The Content Documents are created and managed under the System Software group with. Launch Control System (LCS) project. The System Software product group is lead by NASA Engineering Control and Data Systems branch (NEC3) at Kennedy Space Center. The team is working on creating Operating System Images (OSI) for different platforms (i.e. AIX, Linux, Solaris and Windows). Before the OSI can be created, the team must create a Content Document which provides the information of a workstation or server, with the list of all the software that is to be installed on it and also the set where the hardware belongs. This can be for example in the LDS, the ADS or the FR-l. The objective of this project is to create a User Interface Web application that can manage the information of the Content Documents, with all the correct validations and filters for administrator purposes. For this project we used one of the most excellent tools in agile development applications called Ruby on Rails. This tool helps pragmatic programmers develop Web applications with Rails framework and Ruby programming language. It is very amazing to see how a student can learn about OOP features with the Ruby language, manage the user interface with HTML and CSS, create associations and queries with gems, manage databases and run a server with MYSQL, run shell commands with command prompt and create Web frameworks with Rails. All of this in a real world project and in just fifteen weeks!

    Full Text Available This study examined the association between physical activity (PA and bone mineral content (BMC; g from middle childhood to middle adolescence and compared the impact of vigorous-intensity PA (VPA over moderate- to vigorous-intensity PA (MVPA. Participants from the Iowa Bone Development Study were examined at ages 5, 8, 11, 13, and 15 yr (n=369, 449, 452, 410, 307, respectively. MVPA and VPA (min/day were measured using ActiGraph accelerometers. Anthropometry was used to measure body size and somatic maturity. Spine BMC and hip BMC were measured via dual-energy x-ray absorptiometry. Sex-specific multi-level linear models were fit for spine BMC and hip BMC, adjusted for weight (kg, height (cm, linear age (yr, non-linear age (yr2, and maturity (pre peak height velocity vs. at/post peak height velocity. The interaction effects of PA×maturity and PA×age were tested. We also examined differences in spine BMC and hip BMC between the least (10th percentile and most (90th percentile active participants at each examination period. Results indicated that PA added to prediction of BMC throughout the 10-year follow-up, except MVPA did not predict spine BMC in females. Maturity and age did not modify the PA effect for males nor females. At age 5, the males at the 90th percentile for VPA had 8.5% more hip BMC than males in the 10th percentile for VPA. At age 15, this difference was 2.0%. Females at age 5 in the 90th percentile for VPA had 6.1% more hip BMC than those in the 10th percentile for VPA. The age 15 difference was 1.8%. VPA was associated with BMC at weight-bearing skeletal sites from childhood to adolescence, and the effect was not modified by maturity or age. Our findings indicate the importance of early and sustained interventions that focus on VPA. Approaches focused on MVPA may be inadequate for optimal bone health, particularly for females.

A Delphi Survey of 126 experts followed by an interdisciplinary consensus conference of 14 stakeholders in CAM, general pediatrics and pediatric rheumatology was held to develop consensus on the content of the questionnaires using a nominal group technique. To determine face and content validity of the questionnaires, two groups, including (a) a purposive sample of 22 children with JIA 8 to 18 years and their parents from the Children’s Hospital of Eastern Ontario and the Hospital for Sick Children, and (b) 21 Canadian pediatric rheumatology experts, participated in interviews. Participants were independently asked about the goal, understandability and comprehensiveness of the WHAT questionnaires, as well as the relevance of items. Results Consensus was reached on 17 items of the WHAT questionnaires. The domains found to be relevant were child’s CAM use, factors associated with CAM use, perceived impact of CAM use, and communication about CAM. A total of 15 items in the parent proxy-report questionnaire and 13 items in the child report questionnaire showed adequate content validity. Conclusions Consensus was reached by experts on the content of a pediatric CAM questionnaire. Face and content validity testing and modifications made to the WHAT questionnaires have helped ensure adequate preliminary validity for use in pediatric rheumatology. This constitutes the basis for further testing of these questionnaires in pediatric

    Learning content management systems have become common tools to support the development and delivery of digital learning content for many years. We investigate here how semantic annotation can support the management of change and evolution of learning content. We introduce a semantic information model that supports multi-layered learning content structures, based on which an ontology-based evolution framework is developed. Ontology-enhanced traceability approach is the solution.

    Full Text Available The amount of images or the pictorial data is growing day by day with the expansion of internet services. As the network and development of multimedia technologies are becoming more popular, users are not satisfied with the traditional information retrieval techniques. So nowadays the content based image retrieval are becoming a source of exact and fast retrieval. . It is very difficult for the users to retrieve the required images using a operative and efficient mechanism. There are many techniques which are used to retrieve the images depending upon the requirement of different applications. This paper provides an extensive review of various latest research work and methodologies applied in the field of CBIR. Images are retrieved on the basis of automatically derived features such as, texture, shape and color which is generally referred to as Content-Based Image Retrieval (CBIR. Content based image retrieval is an important research area in image processing, with a vast domain of applications like recognition systems i.e. finger, face, biometrics, medical sciences etc. However, the technology still lacks maturity, and is not yet being used on a significant scale. In the absence of hard evidence on the effectiveness of CBIR techniques in practice, opinion is still sharply divided about their usefulness in handling real-life queries in large and diverse image collections. The concepts which are presently used for CBIR system are all under research.

  19. Changes in contents of somatostatin in hypophysis and arginine vasopressin in hypothalamus of postnatal developing brain induced by low level prenatal β-irradiation of tritiated water in mice

    International Nuclear Information System (INIS)

    Changes in contents of the two kinds of neuropeptides have been measured in the brains of postnatal G57BL/6J strain mice that received accumulative doses of 0, 0.05, 0.10 or 0.30 Gy respectively in utero from tritium β-irradiation during the mother mice's pregnancy from the 12.5th day of gestation to the day of delivery. Dose response relationship for alteration in somatostatin content due to exposure to 0.10 Gy or above was observed, and it was also noted that 0.30 Gy could cause decrease in arginine vasopressin in hypothalamus. These results were consistent with findings in research on brain development and reflex behavior in the literature. 0.10 Gy exposure may represent a threshold for exposure to tritiated water within the range from day 12.5 of gestation to the day of delivery using change in content of somatostatin in hypophysis as a parameter

    Photosynthetic activity of plants is an important factor to assess the micrometeorological effect of plant canopy or to estimate the influence of circumstances such as water stress. Light illumination induces fluorescence from a leaf or suspension of chloroplasts. The red chlorophyll fluorescence had been used to determine the process of the electron transportation in photosynthetic reaction. The fluorescence source other than chlorophyll is not announced sufficiently, but is supposed to be useful to determine the contents of the substance corresponding to physiological response of plants. We developed a fluorescence imaging apparatus to observe spectrum and distribution of laser induced fluorescence from a leaf. Pulsed UV-laser (Nd:YAG) induced blue-green fluorescence and red chlorophyll fluorescence from a green leaf. The pulse modulated measuring light and CCD with image-intensifier (ICCD) enable to detect the fluorescence from plants under illumination. The laser induced fluorescence (LIF) spectra were investigated to estimate the chlorophyll contents in leaves of rice. During the greening course of dark grown etiolated rice leaves, chlorophyll contents were determined using the extraction of leaves and steady state LIF spectra were measured. As a result, the ratio of fluorescent intensity between blue-green and red peaks (F460/F740 and F510/F740) decreased in proportion to alteration of chlorophyll contents respectively. These fluorescence intensity ratios perform more precise estimation of higher chlorophyll contents of leaves than reported red chlorophyll fluorescence intensity ratio (F690/E740). (author)

  1. The early morning development and the evening decay of electron content-latitude profiles at low latitudes and their dependence upon solar declination

    International Nuclear Information System (INIS)

    Electron content-latitude profiles from 200S to 300N have been obtained for 1975 (a period of low solar activity) from an analysis of Faraday fading recordings of INTASAT taken at Hong Kong (long. 114.10E, lat. 22.20N, dip 300N) and Bali (long. 115.20E, lat. 8.90S, dip 35.50S) during the periods 0800 to 1000 and 2000 to 2200 LST (1200E). Hourly median profiles have been computed for both the morning and evening periods for the northern summer and winter, the March/April equinox and also corresponding to a period during which the sun was overhead the magnetic equator (90N). Profiles were most symmetric with respect to the magnetic equator at the equinox. In the morning at the solstices the formation of a single crest of the equatorial anomaly was observed on the winter side of the magnetic equator, though at higher latitudes the electron content values were greatest in the summer hemisphere compared with those of winter hemisphere for the same dip location. In the evening at the solstices the electron content was greatest in the summer hemisphere and for the northern winter a single crest of the equatorial anomaly remained at about 350S dip as late as 2200 LST. At the equinox the profiles showed the greatest content values and the two equatorial anomaly crests were symmetric with respect to the magnetic equator for 2000 to 2100 LST. However from 2100 to 2200 LST the northern crest collapsed near to the magnetic equator. Representative individual profiles corresponding to the varying overhead position of the Sun throughout the year have been given. The evening profiles, in particular, show marked changes of form reflecting the effects of prevailing equatorward winds. (author)

    In recent years, one of the advances of the World Wide Web is social media and one of the fastest growing aspects of social media is the blogosphere. Blogs make content creation easy and are highly accessible through web pages and syndication. With their growing influence, a need has arisen to be able to monitor the opinions and insight revealed within their content. In this paper we describe a technical approach for analyzing the content of blog data using a visual analytic tool, IN-SPIRE, developed by Pacific Northwest National Laboratory. We highlight the capabilities of this tool that are particularly useful for information gathering from blog data.

We develop a model where media firms compete on content provision and advertising revenues, and consumers enjoy network effects from consuming content that other consumers also consume. Media firms have to choose if they are single-content or multi-content, and in the latter case how much content to offer. Competition for advertising revenues gives a two-sided market nature to our model, since advertisers pr...

    Genetically modified (GM) crops have been commercially grown for two decades. GM maize is one of 3 species with the highest acreage and specific events. Many countries established a mandatory labeling of products containing GM material, with thresholds for adventitious presence, to support consumers' freedom of choice. In consequence, coexistence systems need to be introduced to facilitate commercial culture of GM and non-GM crops in the same agricultural area. On modeling adventitious GM cross-pollination distribution within maize fields, we deduced a simple equation to estimate overall GM contents (%GM) of conventional fields, irrespective of its shape and size, and with no previous information on possible GM pollen donor fields. A sampling strategy was designed and experimentally validated in 19 agricultural fields. With 9 samples, %GM quantification requires just one analytical GM determination while identification of the pollen source needs 9 additional analyses. A decision support tool is provided.

  13. Nonsymbiotic hemoglobin-2 leads to an elevated energy state and to a combined increase in polyunsaturated fatty acids and total oil content when overexpressed in developing seeds of transgenic Arabidopsis plants.

    2011-03-01

    Nonsymbiotic hemoglobins are ubiquitously expressed in plants and divided into two different classes based on gene expression pattern and oxygen-binding properties. Most of the published research has been on the function of class 1 hemoglobins. To investigate the role of class 2 hemoglobins, transgenic Arabidopsis (Arabidopsis thaliana) plants were generated overexpressing Arabidopsis hemoglobin-2 (AHb2) under the control of a seed-specific promoter. Overexpression of AHb2 led to a 40% increase in the total fatty acid content of developing and mature seeds in three subsequent generations. This was mainly due to an increase in the polyunsaturated C18:2 (ω-6) linoleic and C18:3 (ω-3) α-linolenic acids. Moreover, AHb2 overexpression led to an increase in the C18:2/C18:1 and C18:3/C18:2 ratios as well as in the C18:3 content in mol % of total fatty acids and in the unsaturation/saturation index of total seed lipids. The increase in fatty acid content was mainly due to a stimulation of the rate of triacylglycerol synthesis, which was attributable to a 3-fold higher energy state and a 2-fold higher sucrose content of the seeds. Under low external oxygen, AHb2 overexpression maintained an up to 5-fold higher energy state and prevented fermentation. This is consistent with AHb2 overexpression results in improved oxygen availability within developing seeds. In contrast to this, overexpression of class 1 hemoglobin did not lead to any significant increase in the metabolic performance of the seeds. These results provide evidence for a specific function of class 2 hemoglobin in seed oil production and in promoting the accumulation of polyunsaturated fatty acids by facilitating oxygen supply in developing seeds.

The objective of this work was to study the effect of dietary fiber concentration and sugar in cereal bars made of oats with a high dietary fiber content. In the research, oat flakes, bran and flour from cultivar UPFA 22, selected on the basis of the dietary fiber and beta-glucans content, were used. The ingredients were used in amounts defined in laboratory tests. The experiment was carried out using a central composite rotational design applicable to the response surface methodology (RSM, and the effects of the sugar syrup concentration (70, 75 and 80 °Brix and dietary fiber content in the formulation (12, 16 and 20% on the chemical composition, calorie value, water activity, microbiology and sensorial characteristics of the cereal bars were evaluated. The results were analyzed by multiple regression and the significant linear, quadratic and interaction terms were used in the second order mathematical model. The results showed that oats can be used as an ingredient when making cereals bars presenting an adequate texture, flavor and appearance. The oats used in the formulation makes cereal bars with high dietary fiber and beta-glucan content. The bars present acceptable sensorial properties, similar to the industrialized bars, with higher acceptability when made with average concentration of sugar and high dietary fiber content. The cereal bars present low water activity and are within sanitary specifications and can be stored for 60 days.

    The contents of antioxidant lignans (Sesamol) in sesame, commercial formulations of tahina and halva, which are processed tahina foods, were determined by Differential Pulse Polarography (DPP) with a capillary hanging mercury drop electrode (HMDE). A platinum wire was used as the counter electrode and Ag/AgCl was the reference electrode. Samples have been analyzed by standard addition procedures and found to be quantitative (p<0.01). Due to the fact that sesamol is an oil-soluble phenolic compound , it was found in the oil levels of sesame, tahina and halvas. Sesame samples contained 51.05-56.46 % in oil whereas tahina samples contained 52.12-53.79 % in oil. The oil percentage of plain halva was found to be 28.79 - 30.13 % (p<0.01). Phenolic lignans sesamol in sesame was 0.26-0.32 mg/100g oil, whereas the sesamol in tahina was 10.98-12.33 mg/100g oil. The sesamol in commercial plain halva samples and the open marketed plain halva samples contained 8.24-9.12 mg/100g oil and 4.97 mg sesamol /100g oil, respectively (R{sup 2}=0.9999) (p<0.01). The proposed Differential Pulse Polarographic (DPP) method is a rapid, reproducible procedure for the simultaneous determination of phenolic lignans in sesame and food products with sesame. It provides an adequate, sensitive, quantitative detection of these nutraceuticals in the commercial food industry. (Author) 26 refs.

  19. Heavy metal contents in growth bands of Porites corals: Record of anthropogenic and human developments from the Jordanian Gulf of Aqaba

    International Nuclear Information System (INIS)

    In order to assess pollutants and impact of environmental changes in the coastal region of the Jordanian Gulf of Aqaba, concentrations of six metals were traced through variations in 5 years growth bands sections of recent Porties coral skeleton. X-radiography showed annual growth band patterns extending back to the year 1925. Baseline metal concentrations in Porites corals were established using 35 years-long metal record from late Holocene coral (deposited in pristine environment) and coral from reef that is least exposed to pollution in the marine reserve in the Gulf of Aqaba. The skeleton samples of the collected corals were acid digested and analyzed for their Cd, Cu, Fe, Mn, Pb and Zn content using Flame Atomic Absorption Spectrophotometer (FAAS). All metal profiles (except Fe and Zn) recorded the same metal signature from recent coral (1925-2005) in which low steady baseline levels were displayed in growth bands older than 1965, similar to those obtained from fossil and unpolluted corals. Most metals showed dramatic increase (ranging from 17% to 300%) in growth band sections younger than 1965 suggesting an extensive contamination of the coastal area since the mid sixties. This date represents the beginning of a period that witnessed increasing coastal activities, constructions and urbanization. This has produced a significant reduction in coral skeletal extension rates. Results from this study strongly suggest that Porites corals have a high tendency to accumulate heavy metals in their skeletons and therefore can serve as proxy tools to monitor and record environmental pollution (bioindicators) in the Gulf of Aqaba

    A full-scale (FS) activated sludge system treating wastewater from a meat rendering plant with a long history of sludge management problems (pin-point flocs; >80% of floc operated continuously over 1.5 years. Distinct differences in the proportion of proteins and polysaccharides associated with extracellular polymeric substances (EPS) were observed when comparing the properties of flocs from the FS and the LB systems. Further differences in the proportion of tightly bound (TB) and loosely bound (LB) fractions of EPS were also observed for flocs derived from conditions where differences in settling and dewatering properties of flocs occurred (i.e. FS and LS systems). FS flocs contained higher levels of EPS along with a higher proportion of LB than TB EPS, and possessing characteristics associated with non-filamentous bulking (SVI >150 mL/g). Floc formed in the LS system, following inoculation from sludge taken from the FS system, was markedly larger in size (>70% of floc >300 μm diameter), spherical in shape, compact and firm, and appeared to be granular in form. Flocs formed in the LS system, when an anoxic phase was introduced into the react stage of the SBR cycle, were found to be more hydrophobic and contained more TB and less loosely bound (LB) EPS when compared to the FS floc. TB-EPS contained a greater amount of protein, whereas the polysaccharide content of LB-EPS was larger. Protein was predominantly localized in the core region of granular flocs where cells were compactly packed. When assessing the operating conditions of the FS and LS systems parameters that appear to impact the floc properties and the transition to a granular form include dissolved oxygen (DO) concentration and food to microorganism (F/M) ratio.

  6. Quasi real-time analysis of mixed-phase clouds using interferometric out-of-focus imaging: development of an algorithm to assess liquid and ice water content

    International Nuclear Information System (INIS)

    According to changes in aircraft certifications rules, instrumentation has to be developed to alert the flight crews of potential icing conditions. The technique developed needs to measure in real time the amount of ice and liquid water encountered by the plane. Interferometric imaging offers an interesting solution: It is currently used to measure the size of regular droplets, and it can further measure the size of irregular particles from the analysis of their speckle-like out-of-focus images. However, conventional image processing needs to be speeded up to be compatible with the real-time detection of icing conditions. This article presents the development of an optimised algorithm to accelerate image processing. The algorithm proposed is based on the detection of each interferogram with the use of the gradient pair vector method. This method is shown to be 13 times faster than the conventional Hough transform. The algorithm is validated on synthetic images of mixed phase clouds, and finally tested and validated in laboratory conditions. This algorithm should have important applications in the size measurement of droplets and ice particles for aircraft safety, cloud microphysics investigation, and more generally in the real-time analysis of triphasic flows using interferometric particle imaging.

    With the advent of set-top boxes, the convergence of TV (broadcasting) and PC (Internet) is set to enter the home environment. Currently, a great deal of activity is occurring in developing standards (TV-Anytime Forum) and devices (TiVo) for local storage on Home Media Servers (HMS). These devices lie at the heart of convergence of the triad: communications/networks - content/media - computing/software. Besides massive storage capacity and being a communications 'gateway', the home media server is characterised by the ability to handle metadata and software that provides an easy to use on-screen interface and intelligent search/content handling facilities. In this paper, we describe a research prototype HMS that is being developed within the GigaCE project at the Telematica Instituut . Our prototype demonstrates advanced search and retrieval (video browsing), adaptive user profiling and an innovative 3D component of the Electronic Program Guide (EPG) which represents online presence. We discuss the use of MPEG-7 for representing metadata, the use of MPEG-21 working draft standards for content identification, description and rights expression, and the use of HMS peer-to-peer content distribution approaches. Finally, we outline explorative user behaviour experiments that aim to investigate the effectiveness of the prototype HMS during development.

    An important part of building a natural-language generation (NLG) system is knowledge acquisition, that is deciding on the specific schemas, plans, grammar rules, and so forth that should be used in the NLG system. We discuss some experiments we have performed with KA for content-selection rules, in the context of building an NLG system which generates health-related material. These experiments suggest that it is useful to supplement corpus analysis with KA techniques developed for building expert systems, such as structured group discussions and think-aloud protocols. They also raise the point that KA issues may influence architectural design issues, in particular the decision on whether a planning approach is used for content selection. We suspect that in some cases, KA may be easier if other constructive expert-system techniques (such as production rules, or case-based reasoning) are used to determine the content of a generated text.

    Full Text Available With the development of multimedia data types and available bandwidth there is huge demand of video retrieval systems, as users shift from text based retrieval systems to content based retrieval systems. Selection of extracted features play an important role in content based video retrieval regardless of video attributes being under consideration. These features are intended for selecting, indexing and ranking according to their potential interest to the user. Good features selection also allows the time and space costs of the retrieval process to be reduced. This survey reviews the interesting features that can beextracted from video data for indexing and retrieval along with similarity measurement methods. We also identify present research issues in area of content based video retrieval systems.

  3. Development of a Univariate Membrane-Based Mid-Infrared Method for Protein Quantitation and Total Lipid Content Analysis of Biological Samples

    Directory of Open Access Journals (Sweden)

    Ivona Strug

    2014-01-01

    Full Text Available Biological samples present a range of complexities from homogeneous purified protein to multicomponent mixtures. Accurate qualification of such samples is paramount to downstream applications. We describe the development of an MIR spectroscopy-based analytical method offering simultaneous protein quantitation (0.25–5 mg/mL and analysis of total lipid or detergent species, as well as the identification of other biomolecules present in biological samples. The method utilizes a hydrophilic PTFE membrane engineered for presentation of aqueous samples in a dried format compatible with fast infrared analysis. Unlike classical quantification techniques, the reported method is amino acid sequence independent and thus applicable to complex samples of unknown composition. By comparison to existing platforms, this MIR-based method enables direct quantification using minimal sample volume (2 µL; it is well-suited where repeat access and limited sample size are critical parameters. Further, accurate results can be derived without specialized training or knowledge of IR spectroscopy. Overall, the simplified application and analysis system provides a more cost-effective alternative to high-throughput IR systems for research laboratories with minimal throughput demands. In summary, the MIR-based system provides a viable alternative to current protein quantitation methods; it also uniquely offers simultaneous qualification of other components, notably lipids and detergents.

    Full Text Available BACKGROUND: Maternal attendance at postnatal clinic visits and timely diagnosis of infant HIV infection are important steps for prevention of mother-to-child transmission (PMTCT of HIV. We aimed to use theory-informed methods to develop text messages targeted at facilitating these steps. METHODS: We conducted five focus group discussions with health workers and women attending antenatal, postnatal, and PMTCT clinics to explore aspects of women's engagement in postnatal HIV care and infant testing. Discussion topics were informed by constructs of the Health Belief Model (HBM and prior empirical research. Qualitative data were coded and analyzed according to the construct of the HBM to which they related. Themes were extracted and used to draft intervention messages. We carried out two stages of further messaging development: messages were presented in a follow-up focus group in order to develop optimal phrasing in local languages. We then further refined the messages, pretested them in individual cognitive interviews with selected health workers, and finalized the messages for the intervention. RESULTS: Findings indicated that brief, personalized, caring, polite, encouraging, and educational text messages would facilitate women bringing their children to clinic after delivery, suggesting that text messages may serve as an important "cue to action." Participants emphasized that messages should not mention HIV due to fear of HIV testing and disclosure. Participants also noted that text messages could capitalize on women's motivation to attend clinic for childhood immunizations. CONCLUSIONS: Applying a multi-stage content development approach to crafting text messages--informed by behavioral theory--resulted in message content that was consistent across different focus groups. This approach could help answer "why" and "how" text messaging may be a useful tool to support maternal and child health. We are evaluating the effect of these messages on

Methods We performed an observational study of discussions at manuscript meetings at JAMA, a major US general medical journal. One of us (KD attended 12 editorial meetings in 2003 as a visitor and took notes recording phrases from discussion surrounding 102 manuscripts. In addition, editors attending the meetings completed a form for each manuscript considered, listing the reasons they were inclined to proceed to the next step in publication and reasons they were not (DR attended 4/12 meetings. We entered the spoken and written phrases into NVivo 2.0. We then developed a schema for classifying the editors' phrases, using an iterative approach. Results Our classification schema has three main themes: science, journalism, and writing. We considered 2,463 phrases, of which 87 related mainly to the manuscript topic and were not classified (total 2,376 classified. Phrases related to science predominated (1,274 or 54%. The editors, most of whom were physicians, also placed major weight on goals important to JAMA's mission (journalism goals such as importance to medicine, strategic emphasis for the journal, interest to the readership, and results (729 or 31% of phrases. About 16% (n = 373 of the phrases used related to writing issues, such as clarity and responses to the referees' comments. Conclusion Classification of editorial discourse provides insight into editorial decision making and concepts that need exploration in future studies.

Classically, a concentration is an amount of any type per volume of liquid or gas system, whereas content is an amount of any type per mass of liquid or gas or solid system. However the concepts 'concentration' and 'content' alone are still ambiguous because, depending on the type of amount of the component (analyte) per volume or mass of a system, there are different types of concentrations and contents. This article attempts to give a clarification of these concepts, mainly based on international recommendations about nomenclature and terminology of metrology, chemistry and clinical laboratory sciences.

    Full Text Available Abstract Background Task shifting and the integration of human immunodeficiency virus (HIV care into primary care services have been identified as possible strategies for improving access to antiretroviral treatment (ART. This paper describes the development and content of an intervention involving these two strategies, as part of the Streamlining Tasks and Roles to Expand Treatment and Care for HIV (STRETCH pragmatic randomised controlled trial. Methods: Developing the intervention The intervention was developed following discussions with senior management, clinicians, and clinic staff. These discussions revealed that the establishment of separate antiretroviral treatment services for HIV had resulted in problems in accessing care due to the large number of patients at ART clinics. The intervention developed therefore combined the shifting from doctors to nurses of prescriptions of antiretrovirals (ARVs for uncomplicated patients and the stepwise integration of HIV care into primary care services. Results: Components of the intervention The intervention consisted of regulatory changes, training, and guidelines to support nurse ART prescription, local management teams, an implementation toolkit, and a flexible, phased introduction. Nurse supervisors were equipped to train intervention clinic nurses in ART prescription using outreach education and an integrated primary care guideline. Management teams were set up and a STRETCH coordinator was appointed to oversee the implementation process. Discussion Three important processes were used in developing and implementing this intervention: active participation of clinic staff and local and provincial management, educational outreach to train nurses in intervention sites, and an external facilitator to support all stages of the intervention rollout. The STRETCH trial is registered with Current Control Trials ISRCTN46836853.

    2006-04-01

    The lycopene content of 50 commercial cultivars of seeded and seedless red-fleshed watermelons was determined. Scanning colorimetric and spectrophotometric assays of total lycopene were used to separate watermelon cultivars into low (90 mg/kg fw). Cultivars varied greatly in lycopene content, ranging from 33 to 100 mg/kg. Most of the seeded hybrid cultivars had average lycopene contents. Sixteen of the 33 seedless types had lycopene contents in the high and very high ranges. All-trans-lycopene was the predominant carotenoid (84-97%) in all watermelon cultivars measured by high-performance liquid chromatography, but the germplasm differed in the relative amounts of cis-lycopene, beta-carotene, and phytofluene. Red-fleshed watermelon genotypes vary extensively in carotenoid content and offer opportunities for developing watermelons with specifically enhanced carotenoids. PMID:16569049

  3. Content metamorphosis in synthetic holography

    International Nuclear Information System (INIS)

    A synthetic hologram is an optical system made of hundreds of images amalgamated in a structure of holographic cells. Each of these images represents a point of view on a three-dimensional space which makes us consider synthetic holography as a multiple points of view perspective system. In the composition of a computer graphics scene for a synthetic hologram, the field of view of the holographic image can be divided into several viewing zones. We can attribute these divisions to any object or image feature independently and operate different transformations on image content. In computer generated holography, we tend to consider content variations as a continuous animation much like a short movie. However, by composing sequential variations of image features in relation with spatial divisions, we can build new narrative forms distinct from linear cinematographic narration. When observers move freely and change their viewing positions, they travel from one field of view division to another. In synthetic holography, metamorphoses of image content are within the observer's path. In all imaging Medias, the transformation of image features in synchronisation with the observer's position is a rare occurrence. However, this is a predominant characteristic of synthetic holography. This paper describes some of my experimental works in the development of metamorphic holographic images.

    Full Text Available In this study, we developed a bioassay to quantify the ricin toxin content of castor bean seeds. Existing quantification methods do not always reflect actual toxicity of the seeds analyzed, which may present lower ricin content even though they are more toxic than seeds presenting a higher content of ricin. This is because these methods actually measure the addition of ricin RCA, which is a compound less toxic than pure ricin. We decided to use in this study, the nematode Caenorhabditis elegans, which has been widely used by the pharmaceutical industry. We tested two strains of C. elegans using different methods in 8 experiments. We examined 4 methods of extracting the ricin complex and 3 methods of exposing the nematodes. Among the nematode strains and ricin extraction methods tested, we concluded that the best strain for testing ricin toxicity was the strain called N2 and that the best method for ricin extraction was a rotating bath followed by centrifugation and exposing the nematodes in 24 well plates with a solution of nematodes extracted from the media with destilated waterexposing the nematodes in 24-well plates This method is inexpensive, quick and adequate for the selection of offspring with lower RIP content.Foi desenvolvido um bioensaio para quantificar o teor de ricina nas sementes de mamona. Os métodos de quantificação existentes não refletem a toxidez real das sementes analizadas, que pode mostrar um resultado de menor teor de ricina e ainda assim ser mais toxico do que as sementes que apresentaram teores maiores. Isto ocorre por que estes métodos medem alem da ricina a RCA, que é um composto menos tóxico que a ricina pura. Foi decidido utilizar neste estudo o nematoide Caenorhabditis elegans, que tem sido amplamente utilizado na industria farmacêutica. Foram testadas duas estirpes de C.elegans usadas em diferentes métodos contando com 8 experimentos distintos. nós examinamos 4 métodos de extração de ricina e 3 m

  5. Information content of polarization measurements

    International Nuclear Information System (INIS)

    Information entropy is applied to the state of knowledge of reaction amplitudes in pseudoscalar meson photoproduction, and a scheme is developed that quantifies the information content of a measured set of polarization observables. It is shown that this definition of information is a more practical measure of the quality of a set of measured observables than whether the combination is a mathematically complete set. It is also shown that, when experimental uncertainty is introduced, complete sets of measurements do not necessarily remove ambiguities and that experiments should strive to measure as many observables as practical to extract amplitudes.

    Multimodal interfaces, combining the use of speech, graphics, gestures, and facial expressions in input and output, promise to provide new possibilities to deal with information in more effective and efficient ways, supporting for instance: - the understanding of possibly imprecise, partial or ambiguous multimodal input; - the generation of coordinated, cohesive, and coherent multimodal presentations; - the management of multimodal interaction (e.g., task completion, adapting the interface, error prevention) by representing and exploiting models of the user, the domain, the task, the interactive context, and the media (e.g. text, audio, video). The present document is intended to support the discussion on multimodal content representation, its possible objectives and basic constraints, and how the definition of a generic representation framework for multimodal content representation may be approached.

    Full Text Available Content based video retrieval is an approach for facilitating the searching and browsing of large image collections over World Wide Web. In this approach, video analysis is conducted on low level visual properties extracted from video frame. We believed that in order to create an effective video retrieval system, visual perception must be taken into account. We conjectured that a technique which employs multiple features for indexing and retrieval would be more effective in the discrimination and search tasks of videos. In order to validate this claim, content based indexing and retrieval systems were implemented using color histogram, various texture features and other approaches. Videos were stored in Oracle 9i Database and a user study measured correctness of response.

In order to validate this claim, content based indexing and retrieval systems were implemented using color histogram, various texture features and other approaches. Videos were stored in Oracle 9i Database and a user study measured correctness of response.

  17. QTL analysis using SNP markers developed by next-generation sequencing for identification of candidate genes controlling 4-methylthio-3-butenyl glucosinolate contents in roots of radish, Raphanus sativus L.

    Directory of Open Access Journals (Sweden)

    Zhongwei Zou

    Full Text Available SNP markers for QTL analysis of 4-MTB-GSL contents in radish roots were developed by determining nucleotide sequences of bulked PCR products using a next-generation sequencer. DNA fragments were amplified from two radish lines by multiplex PCR with six primer pairs, and those amplified by 2,880 primer pairs were mixed and sequenced. By assembling sequence data, 1,953 SNPs in 750 DNA fragments, 437 of which have been previously mapped in a linkage map, were identified. A linkage map of nine linkage groups was constructed with 188 markers, and five QTLs were detected in two F(2 populations, three of them accounting for more than 50% of the total phenotypic variance being repeatedly detected. In the identified QTL regions, nine SNP markers were newly produced. By synteny analysis of the QTLs regions with Arabidopsis thaliana and Brassica rapa genome sequences, three candidate genes were selected, i.e., RsMAM3 for production of aliphatic glucosinolates linked to GSL-QTL-4, RsIPMDH1 for leucine biosynthesis showing strong co-expression with glucosinolate biosynthesis genes linked to GSL-QTL-2, and RsBCAT4 for branched-chain amino acid aminotransferase linked to GSL-QTL-1. Nucleotide sequences and expression of these genes suggested their possible function in 4MTB-GSL biosynthesis in radish roots.

    The present study is primarily aimed at an audience of evolutionary biologists in the broad sense for Parts 1-3, as well as at scientists from other professional disciplines looking for new approaches to explore phenomena in nature. However, the content is in general not written as technical text or filled with equations that make it utterly incomprehensible for 'normal' people, although they would have to skip strictly professional biochemical and biological terms that are a constituent part of the evidence in a scientific sense. Therefore, large parts of Part 2 may also be enjoyed by a broader audience with little prior insight into evolutionary biology or science, when in search of explanations for the phenomena that we see in nature. Finally, Part 4 - with a view into Parts 1-3 - is meant for systems analysts and researchers striving to find a general systems theory. Parts 3 and 4 are the only parts that are not relevant for a general audience. A Note for the Reader Extensive use of references in scientific literature is generally perceived as evidence in favour of an author's statement when synthesizing findings in the literature on a given topic. At the same time, when applying citations of such literature one has to copy the text literally including printing errors, references and everything relevant, unless otherwise explicitly stated. Including such references in cited text often a) creates confusion because such references are not included in the reference list even if they appear in the text; and furthermore b) they tend to add an unnecessary cognitive burden on the reader. Therefore, references with cited text in the present publication have been replaced by the Italicized text 'ref' or 'refs', i.e. single or plural, depending on the number of references omitted in a given place.

    Full Text Available Content Management Systems (CMS provide to its users the ability to publish on the Web with no need to have experience in developing web pages, this way CMS also participates in the expansion of reducing quality of content placed on the web similarly to Web 2.0 tools. The mechanism of validating content indicates a high level of quality content control while putting users as main players according to Web 2.0 standards, from this prospects we develop Validated Content Management System VCMS as a new Web 2.0 tool that supports content validation mechanism. The VCMS system requires collaboration between users when content is being static validated. Real-time synchronization between users during collaboration on the same project can make this process easier and brings more rapidity to content publication while maintaining the mechanisms that allows quality control in our system. In this article we present the technic of implementing real time interaction between users during collaboration on the same content. We focus on promoting the What You See Is What You Get (WYSIWYG editor to support Real-time collaboration between multiple content generators. . The approach presented in this paper can be integrated to any collaborative Content Management System and also can be used in all collaborative applications that generate Web content such as blogs or wikis offering to these tools the feature of collaborating on the same content between multiple users in real-time.

The main tasks that need to be solved in order to achieve this goal were formulated. We have developed and proved structurally-logical chart of the elements of the institutional infrastructure. The content of the institutional infrastructure of the car are presented and justified. The analysis condition of the car market’s institutional infrastructure showed the problems associated with the state of institutions which have an impact on the functioning of the car market. Measures to stimulate the car market does not cover entire sector as a whole, and imported institutions do not give the expected effect because of inconsistency formal and informal elements of the institutional infrastructure. Presented assessment of the institutional infrastructure of the car market confirms the dependence of the state of the industry market cars from institutional infrastructure.

  2. Remote-Handled Transuranic Content Codes

    International Nuclear Information System (INIS)

    The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document represents the development of a uniform content code system for RH-TRU waste to be transported in the 72-Bcask. It will be used to convert existing waste form numbers, content codes, and site-specific identification codes into a system that is uniform across the U.S. Department of Energy (DOE) sites.The existing waste codes at the sites can be grouped under uniform content codes without any lossof waste characterization information. The RH-TRUCON document provides an all-encompassing description for each content code and compiles this information for all DOE sites. Compliance with waste generation, processing, and certification procedures at the sites (outlined in this document foreach content code) ensures that prohibited waste forms are not present in the waste. The content code gives an overall description of the RH-TRU waste material in terms of processes and packaging, as well as the generation location. This helps to provide cradle-to-grave traceability of the waste material so that the various actions required to assess its qualification as payload for the 72-B cask can be performed. The content codes also impose restrictions and requirements on the manner in which a payload can be assembled. The RH-TRU Waste Authorized Methods for Payload Control (RH-TRAMPAC), Appendix 1.3.7 of the 72-B Cask Safety Analysis Report (SAR), describes the current governing procedures applicable for the qualification of waste as payload for the 72-B cask. The logic for this classification is presented in the 72-B Cask SAR. Together, these documents (RH-TRUCON, RH-TRAMPAC, and relevant sections of the 72-B Cask SAR) present the foundation and justification for classifying RH-TRU waste into content codes. Only content codes described in thisdocument can be considered for transport in the 72-B cask. Revisions to this document will be madeas additional waste qualifies for transport.

    Full Text Available Advocates of the content-based approach believed that a language can be learnt effectively when it is the medium of instruction rather than just a subject. Integrating English and content as part of instruction has become one of the cornerstones of second language pedagogy. Researchers claimed that there are many benefits of integrating English and content instruction. Among the benefits are the increase in students’ interest with content themes, meaningful input and understanding. In 2003, the Malaysian Ministry of Education introduced the teaching and learning of science and mathematics in English for Year One, Form One and Lower Six Form in all government public schools. This paper describes the challenges faced by teachers when they are required to teach content subjects such as science and mathematics in English. The focus of the paper is on the teachers’ pedagogical skills and content knowldge which comprises subject matter content, pedagogical approach, classroom management, use of resources, assessment, preparation of teaching materials, managing students, teachers’ compensatory communication strategies, use of first language and teachers’ perspectives of teaching content subjects in English. Data were obtained from a self-report questionnaire administered to 495 secondary school teachers in West Malaysia. Results from the study provide implications for school administrators in making decisions in assignment of capable teachers to teach the various levels of classes. Suggestions for teacher self-development and life-long learning efforts are also provided.

    Eight general practitioners participated in a survey of content of general practice. This is useful as an indicator or morbidity in the community as well as of workload of general practice. A total of 3164 consultations were recorded, of which 2764 (87%) were because of an illness and the rest (13%) for other reasons like medical examinations, antenatal check, family planning advice, pregnancy tests, pap smear and vaccination. The old and the young have high consultation rates for an illness, men consulted as often as women. The most common illness seen was upper respiratory tract infections, accounting for 37% of all illnesses. Other common minor illnesses were skin infections (6%), genito-urinary infections (5%), minor musculoskeletal (6%) and gastrointestinal (6%) complaints as well as minor injuries and cuts (4%). Major disorders form an unusually low proportion (18%) of all illnesses seen, in comparison with figures from United Kingdom. The common major disorders seen were hypertension, asthma, chronic rheumatic disorders and diabetes. Circulatory disorders were remarkably rare, accounting for only 1% of illnesses. Psychological disorders, both major and minor, were also rarely seen, accounting for only 1% of illnesses which is in marked contrast with figures from the United Kingdom. Factors contributing to these notable findings are discussed. PMID:1839420

    The Remote-Handled Transuranic (RH-TRU) Content Codes (RH-TRUCON) document representsthe development of a uniform content code system for RH-TRU waste to be transported in the 72-Bcask. It will be used to convert existing waste form numbers, content codes, and site-specificidentification codes into a system that is uniform across the U.S. Department of Energy (DOE) sites.The existing waste codes at the sites can be grouped under uniform content codes without any lossof waste characterization information. The RH-TRUCON document provides an all-encompassing|description for each content code and compiles this information for all DOE sites. Compliance withwaste generation, processing, and certification procedures at the sites (outlined in this document foreach content code) ensures that prohibited waste forms are not present in the waste. The contentcode gives an overall description of the RH-TRU waste material in terms of processes and|packaging, as well as the generation location. This helps to provide cradle-to-grave traceability ofthe waste material so that the various actions required to assess its qualification as payload for the72-B cask can be performed. The content codes also impose restrictions and requirements on themanner in which a payload can be assembled.The RH-TRU Waste Authorized Methods for Payload Control (RH-TRAMPAC), Appendix 1.3.7of the 72-B Cask Safety Analysis Report (SAR), describes the current governing procedures|applicable for the qualification of waste as payload for the 72-B cask. The logic for this|classification is presented in the 72-B Cask SAR. Together, these documents (RH-TRUCON,|RH-TRAMPAC, and relevant sections of the 72-B Cask SAR) present the foundation and|justification for classifying RH-TRU waste into content codes. Only content codes described in thisdocument can be considered for transport in the 72-B cask. Revisions to this document will be madeas additional waste qualifies for transport. |Each content code uniquely

    Noviello, C.; Acampa, P.; Mango Furnari, M.

    Network content delivery and documents sharing is possible using a variety of technologies, such as distributed databases, service-oriented applications, and so forth. The development of such systems is a complex job, because document life cycle involves a strong cooperation between domain experts and software developers. Furthermore, the emerging software methodologies, such as the service-oriented architecture and knowledge organization (e.g., semantic web) did not really solve the problems faced in a real distributed and cooperating settlement. In this chapter the authors' efforts to design and deploy a distribute and cooperating content management system are described. The main features of the system are a user configurable document type definition and a management middleware layer. It allows CMS developers to orchestrate the composition of specialized software components around the structure of a document. In this chapter are also reported some of the experiences gained on deploying the developed framework in a cultural heritage dissemination settlement.

    Full Text Available Distribution of digital content is a key revenue opportunity for telecommunications carriers. As media content moves from analog and physical media-based distribution to digital on-line distribution, a great opportunity exists for carriers to claim their role in the media value chain and grow revenue by enhancing their broadband “all you can eat” high speed Internet access offer to incorporate delivery of a variety of paid content. By offering a distributed peer to peer content delivery capability with authentication, personalization and payment functions, carriers can gain a larger portion of the revenue paid for content both within and beyond their traditional service domains. This paper describes an approach to digital content distribution that leverages existing Intelligent Network infrastructure that many carriers already possess, as well as Web Services.

  4. Development of an in-situ diagnostic for the measurement of the hydrogen content of amorphous hydrocarbon layers in fusion devices; Entwicklung einer In-situ-Messmethode zur Bestimmung des Wasserstoffgehalts amorpher Kohlenwasserstoffschichten in Fusionsanlagen

    A diagnostic method, the laser-induced thermal desorption spectroscopy (LDS), is developed to measure in situ the hydrogen inventory in the surface of plasma-facing components in fusion experiments. Its capabilities will be demonstrated in TEXTOR. In LDS, during the plasma discharge a laser beam is used to heat a spot on a surface close to the plasma to a temperature of 1400 to 2100 K to a depth of 100 {mu}m. Trapped hydrogen will be released into the plasma where it emits line radiation. The emitted H{sub a}-light is quantitatively measured. The amount of released hydrogen is calculated from the intensity of this emission using conversion factors (S/XB){sub eff}. The laser light (Nd:YAG, 1064 nm) is conducted via light fibres. At TEXTOR, a 5 mm{sup 2} sized homogeneous laser spot is created with a pulse duration of 1.5 ms, and an Energy of 5 J, typically. Below the laser spot a volume of at most 1 mm{sup 3} is desorbed. The generated temperature is calculated numerically and indirectly deduced from surface changings. Depending on the conditions during the layer formation the hydrogen content of the hydrocarbon layer will vary and different fractions of the released molecules (H{sub 2}, CH{sub 4}, C{sub 2}H{sub 4}) are created during the laser heating. The release of atomic hydrogen by laser desorption was not found. The emitted light is measured by means of narrow-band interference filters and a CCD-camera. The fraction of the light emission which lies outside the observation volume is estimated using simulations of the emission by the neutral gas transport Monte Carlo code EIRENE for each molecular fraction. Conversion factors (S/XB){sub eff} were measured in various reference plasmas (T{sub e}=22-30 eV, n{sub e}=1-11 x 10{sup 18} m{sup -3} and T{sub e}=50-74 eV, n{sub e}=1-5 x 10{sup 18} m{sup -3}) by desorbing prepared graphite samples which release a known amount of hydrogen with a known molecular distribution. LDS measurements were carried out in TEXTOR at

    The purpose of developing a core content for subspecialty training in clinical ultrasonography (US) is to standardize the education and qualifications required to provide oversight of US training, clinical use, and administration to improve patient care. This core content would be mastered by a fellow as a separate and unique postgraduate training, beyond that obtained during an emergency medicine (EM) residency or during medical school. The core content defines the training parameters, resources, and knowledge of clinical US necessary to direct clinical US divisions within medical specialties. Additionally, it is intended to inform fellowship directors and candidates for certification of the full range of content that might appear in future examinations. This article describes the development of the core content and presents the core content in its entirety. PMID:24730409

    [Ancient Mediterranean Civilizations] Title: On Poseidon's Image in Homeric Epics Author: Zhu Yizhang, Lecturer, School of History and Culture, Shandong University, Jinan, Shandong, 250100, China. Abstract: Poseidon was an important role in religion, myth and literature of ancient Greece. His religious functions, and status in mythical image in literature were mainly established by Homeric Epics. Poseidon doesn't only appear frequently in the Homeric Epics but also influences the development of the plots directly; therefore, he could be seen as one of the most important gods in the Epics. But Homeric Epics do not introduce his basic image clearly. In Homeric Epics, Poseidon carries the deity and humanity aspect of the figure, and the latter was emphasized, which implied his archetype was a mortal wanax.

  16. Calculation of the debris flow concentration based on clay content

    The debris flow clay content has very tremendous influence on its concentration (γC). It is reported that the concentration can be calculated by applying the relative polynomial based on the clay content. Here one polynomial model and one logarithm model to calculate the concentration based on the clay content for both the ordinary debris flow and viscous debris flow are obtained. The result derives from the statistics and analysis of the relationship between the debris flow concentrations and clay content in 45 debris flow sites located in the southwest of China. The models can be applied for the concentration calculation to those debris flows that are impossible to observe. The models are available to calculate the debris flow concentration, the principles of which are in the clay content affecting on the debris flow formation, movement and suspending particle diameter. The mechanism of the relationship of the clay content and concentration is clear and reliable. The debris flow is usually of micro-viscous when the clay content is low (<3%), by analyzing the developing tendency on the basics of the relationship between the clay content and debris flow concentration. Indeed, the less the clay content, the less the concentration for most debris flows. The debris flow tends to become the water rock flow or the hyperconcentrated flow with the clay content decrease. Through statistics it is apt to transform the soil into the viscous debris flow when the clay content of ranges is in 3%-18%. Its concentration increases with the increasing of the clay content when the clay content is between 5% and 10%. But the value decreases with the increasing of the clay content when the clay content is between 10% and 18%. It is apt to transform the soil into the mudflow, when the clay content exceeds 18%. The concentration of the mudflow usually decreases with the increase of the clay content, and this developing tendency reverses to that of the micro-viscous debris flow. There is

    Micro-Foundation of Macro-National Analysis: A Review on the Western Banal Nationalism Theory and Its Complement Gao Qiqi(1) Abstract: In recent years, banal nationalism has already created relatively important influence in western national theory areas, and stimulated new thoughts of two different paths: banal sub-nationalism and banal supra-nationalism. The emergence of banal nationalism theory means that micro-national analysis launched by primordialism is promoted into a more normative analyzing period. The meaning of banal nationalism is that it partly lowers the conflict and explosivity embedded in macro-national analysis, and it shows a national meaning world around the individual as a national member. The difficulties of this theory are two points, namely, the lack of consideration of elite function and the lack of integration of historical changes. In this article, the author tries to introduce the knowledge of western sociology to overcome those difficulties of banal nationalism. Enlightened by Collins's interaction ritual chains theory, the author puts forward an analysis framework of intra-national interaction field in order to summarize and generalize the western banal nationalism theory from the perspective of sociology; on the basis of it, tries to complement and develop the western banal nationalism theory.

    The Social Competition and the Construction of Ethnic Group: A Refection of Western Theory about Resource Competition Guan Kai(1) Abstract: The theory about resource competition claims that ethnic group, as a symbol, is a kind of toot in the social competition, and that on certain social conditions, people can be organized by ethnic group to strive for social resource, hence the boundary among ethnic groups is drawn. So the need of social competition and the strategy of individual and collectivity to meet it becomes the basic power to construct ethnic group. The paper reviews the origin and development of the theory about resource competition of ethnic group, and the relative cases; on the basis of the above, responds to the theory and analyzes its limitation. At the same time, the paper also tries to introduces a new variable--state--to the theory, that is to say, add a viewpoints of state in the theory about resource competition whose focus is on the society, and discovers the important role of state which means a competition coordinator and its function and effect in the construction of ethnic group. Keywords : resource competition; ethnic group ; state; construction of ethnic group ; competition of ethnic group.

    Soil texture and the soil water characteristic are key properties used to estimate flow and transport parameters. Determination of clay content is therefore critical for understanding of plot-scale soil heterogeneity. With increasing interest in proximal soil sensing, there is the need to relate obtained signals to soil properties of interest. Inference of soil texture, especially clay mineral content, from instrument response from electromagnetic induction and radiometric methods is of subst...
