    Shimada, K; Hirotani, M; Yokokawa, H; Yoshida, H; Makita, K; Yamazaki-Murase, M; Tanabe, H C; Sadato, N

    2015-08-01

    This functional magnetic resonance imaging (fMRI) study investigated the brain regions underlying language task performance in adult second language (L2) learners. Specifically, we identified brain regions where the level of activation was associated with L2 fluency levels. Thirty Japanese-speaking adults participated in the study. All participants were L2 learners of English and had achieved varying levels of fluency, as determined by a standardized L2 English proficiency test, the Versant English Test (Pearson Education Inc., 2011). When participants performed the oral sentence building task from the production tasks administered, the dorsal part of the left inferior frontal gyrus (dIFG) showed activation patterns that differed depending on the L2 fluency levels: The more fluent the participants were, the more dIFG activation decreased. This decreased activation of the dIFG might reflect the increased automaticity of a syntactic building process. In contrast, when participants performed an oral story comprehension task, the left posterior superior temporal gyrus (pSTG) showed increased activation with higher fluency levels. This suggests that the learners with higher L2 fluency were actively engaged in post-syntactic integration processing supported by the left pSTG. These data imply that L2 fluency predicts neural resource allocation during language comprehension tasks as well as in production tasks. This study sheds light on the neural underpinnings of L2 learning by identifying the brain regions recruited during different language tasks across different modalities (production vs. comprehension).

  8. A Development of Game-Based Learning Environment to Activate Interaction among Learners

    NASA Astrophysics Data System (ADS)

    Takaoka, Ryo; Shimokawa, Masayuki; Okamoto, Toshio

    Many studies and systems that incorporate elements such as “pleasure” and “fun” in the game to improve a learner's motivation have been developed in the field of learning environments. However, few are the studies of situations where many learners gather at a single computer and participate in a game-based learning environment (GBLE), and where the GBLE designs the learning process by controlling the interactions between learners such as competition, collaboration, and learning by teaching. Therefore, the purpose of this study is to propose a framework of educational control that induces and activates interaction between learners intentionally to create a learning opportunity that is based on the knowledge understanding model of each learner. In this paper, we explain the design philosophy and the framework of our GBLE called “Who becomes the king in the country of mathematics?” from a game viewpoint and describe the method of learning support control in the learning environment. In addition, we report the results of the learning experiment with our GBLE, which we carried out in a junior high school, and include some comments by a principal and a teacher. From the results of the experiment and some comments, we noticed that a game may play a significant role in weakening the learning relationship among students and creating new relationships in the world of the game. Furthermore, we discovered that learning support control of the GBLE has led to activation of the interaction between learners to some extent.

  7. The effect of curricular activities on learner autonomy: the perspective of undergraduate mechanical engineering students

    NASA Astrophysics Data System (ADS)

    Duarte, M.; Leite, C.; Mouraz, A.

    2016-01-01

    This study researches how first-year engineering students perceived the influence of curricular activities on their own learning autonomy, measured with an adaptation of the Personal Responsibility Orientation to Self-direction in Learning Scale (PRO-SDLS). Participants were questioned to assess the influence of the teacher's role. The results indicate that learners' characteristics (motivation and self-efficacy) contribute more to learner autonomy (LA) than the teaching-learning transaction (control and initiative), as in the original PRO-SDLS validation. The most autonomous learners presented higher values in all LA components and dimensions, but the differences were greater in motivation and initiative. The participants with higher LA were not as dependent on the teacher, regarding assessment, the completion of classroom tasks and deadlines. Regardless of the degree of autonomy in learning, all participants viewed teachers as the main source of information. Therefore, LA plays an important role in teaching activities planning. Suggestions for adjustments and more flexible learning scenarios are formulated.

  8. Cross-language activation in children's speech production: evidence from second language learners, bilinguals, and trilinguals.

    PubMed

    Poarch, Gregory J; van Hell, Janet G

    2012-03-01

    In five experiments, we examined cross-language activation during speech production in various groups of bilinguals and trilinguals who differed in nonnative language proficiency, language learning background, and age. In Experiments 1, 2, 3, and 5, German 5- to 8-year-old second language learners of English, German-English bilinguals, German-English-Language X trilinguals, and adult German-English bilinguals, respectively, named pictures in German and in English; in Experiment 4, 6- to 8-year-old German monolinguals named pictures in German. In both language conditions, cognate status was manipulated. We found that the bidirectional cognate facilitation effect was significant in all groups except the German monolinguals (Experiment 4) and, critically, the child second language learners (Experiment 1) in whom only native language (L1) German had an effect on second language (L2) English. The findings demonstrate how the integration of languages into a child's system follows a developmental path that, at lower levels of proficiency, allows only limited cross-language activation. The results are interpreted against the backdrop of the developing language systems of the children both for early second language learners and for early bi- and trilinguals. PMID:22138311

  13. Innovative Strategies for Empowering Your Students to Become Active, Responsible Learners

    NASA Astrophysics Data System (ADS)

    Hufnagel, B.

    2011-09-01

    The economy continues to sputter along, and the repercussions are now hitting hard at publicly-funded colleges and universities, with enrollment increasing and funding decreasing. Funding agencies are starting to look at retention and completion rates as a way to allocate scarce dollars. Improving these rates is also one way to increase the future stream of tuition; students who can't pass introductory classes like ASTRO101 won't enroll and pay tuition for the next level, and they won't complete their degree. So what can you, a mere professor of astronomy, do? Tired of the "What do you want me to know?" questions? Provide your students with learner-centered structures to help them learn more deeply. Do your students resist active-engagement techniques and hate group work? Share empowerment strategies for helping students become active, responsible learners who can thrive in a learner-centered environment. Do you think that it's wrong for the freshman classes to be over-crowded, yet your sophomore classes don't get enough students or don't even exist? After using the proven curriculum of On Course, college and universities across the country have improved their retention across a wide range of disciplines (http://www.OnCourseWorkshop.com/Data.htm). Experience a sample of the fun and engaging activities developed over two decades to help students (1) accept personal responsibility, (2) discover self motivation, (3) master self-management, (4) use interdependence, (5) gain self-awareness, (6) adopt lifelong learning, (7) develop emotional intelligence, and (8) believe in themselves. Since this is only a one-hour workshop, we will focus on choices one and four: to be successful, students need to see themselves as the primary cause of their outcomes and experiences and to build mutually supportive relationships in our classroom and labs. Outcomes: (1) one ASTRO101 Course-ready activity to help students accept personal responsibility; (2) one ASTRO101 Course

  7. Clustering of Risk Behaviors and their Social Determinants among Primary School Learners in Beijing, China: A Cross-sectional Study

    PubMed Central

    Zhang, Yan; Ji, Ying

    2015-01-01

    Background: Studies in developed countries reveal that poor lifestyle choices triggering diseases typically cluster among children. However, there is insufficient evidence on the clustering of risk behaviors among children in developing countries. This study aimed to determine the clustering of risk behaviors and their social determinants among 4th-and 5th -grade learners in Beijing, China. Methods: The sample comprised of 967 learners from six primary schools enrolled migrant and resident learners by two-stage stratified cluster sampling. Prevalence denoted the risk behaviors and their clustering. A log-linear model was used to explore the clustering patterns. Ordinal logistic regression determined the influence of demographic characteristics, school environment, and family context on behavioral clustering. Results: The prevalence of none, one, two, and three or more risk factors was 61.2%, 20.0%, 10.8%, and 8.1% for infectious diseases and 46.0%, 30.6%, 15.4%, and 8.0% for chronic diseases, respectively. Some behaviors appeared dependent and were more likely to be observed together. The three most influential factors for infectious diseases were school type (odds ratio [OR] =4.47, 95% confidence interval [CI] 3.00–6.66), school located in an inner suburb (OR = 0.27, 95% CI 0.18–0.38), and gender (OR = 0.56, 95% CI 0.42–0.74). Regarding risk behaviors for chronic diseases, clustering was not associated with household registration status and number of appliances, but was significantly associated with school type (OR = 5.36, 95% CI 3.72–7.73), school located in an inner suburb (OR = 0.59, 95% CI 0.43–0.81), and gender (OR = 0.61, 95% CI 0.47–0.78). School environment variables were the most significant contributor to the number of risk behaviors. Conclusions: The characteristics of schools enrolling migrants and residents influenced the number of risk behaviors. Therefore, improved school conditions and integrated behavioral interventions are

  15. The effects of data-driven learning activities on EFL learners' writing development.

    PubMed

    Luo, Qinqin

    2016-01-01

    Data-driven learning has been proved as an effective approach in helping learners solve various writing problems such as correcting lexical or grammatical errors, improving the use of collocations and generating ideas in writing, etc. This article reports on an empirical study in which data-driven learning was accomplished with the assistance of the user-friendly BNCweb, and presents the evaluation of the outcome by comparing the effectiveness of BNCweb and a search engine Baidu which is most commonly used as reference resource by Chinese learners of English as a foreign language. The quantitative results about 48 Chinese college students revealed that the experimental group which used BNCweb performed significantly better in the post-test in terms of writing fluency and accuracy, as compared with the control group which used the search engine Baidu. However, no significant difference was found between the two groups in terms of writing complexity. The qualitative results about the interview revealed that learners generally showed a positive attitude toward the use of BNCweb but there were still some problems of using corpora in the writing process, thus the combined use of corpora and other types of reference resource was suggested as a possible way to counter the potential barriers for Chinese learners of English.

  12. Exploring Shifts in Middle School Learners' Modeling Activity While Generating Drawings, Animations, and Computational Simulations of Molecular Diffusion

    NASA Astrophysics Data System (ADS)

    Wilkerson-Jerde, Michelle H.; Gravel, Brian E.; Macrander, Christopher A.

    2015-04-01

    Modeling and using technology are two practices of particular interest to K-12 science educators. These practices are inextricably linked among professionals, who engage in modeling activity with and across a variety of representational technologies. In this paper, we explore the practices of five sixth-grade girls as they generated models of smell diffusion using drawing, stop-motion animation, and computational simulation during a multi-day workshop. We analyze video, student discourse, and artifacts to address the questions: In what ways did learners' modeling practices, reasoning about mechanism, and ideas about smell shift as they worked across this variety of representational technologies? And, what supports enabled them to persist and progress in the modeling activity? We found that the girls engaged in two distinct modeling cycles that reflected persistence and deepening engagement in the task. In the first, messing about, they focused on describing and representing many ideas related to the spread of smell at once. In the second, digging in, they focused on testing and revising specific mechanisms that underlie smell diffusion. Upon deeper analysis, we found these cycles were linked to the girls' invention of "oogtom," a representational object that encapsulated many ideas from the first cycle and allowed the girls to restart modeling with the mechanistic focus required to construct simulations. We analyze the role of activity design, facilitation, and technological infrastructure in this pattern of engagement over the course of the workshop and discuss implications for future research, curriculum design, and classroom practice.

  16. Objects prompt authentic scientific activities among learners in a museum programme

    NASA Astrophysics Data System (ADS)

    Achiam, Marianne; Simony, Leonora; Kramer Lindow, Bent Erik

    2016-04-01

    Although the scientific disciplines conduct practical work in different ways, all consider practical work as the essential way of connecting objects and phenomena with ideas and the abstract. Accordingly, practical work is regarded as central to science education as well. We investigate a practical, object-based palaeontology programme at a natural history museum to identify how palaeontological objects prompt scientific activity among upper secondary school students. We first construct a theoretical framework based on an analysis of the programme's palaeontological content. From this, we build our reference model, which considers the specimens used in the programme, possible palaeontological interpretations of these specimens, and the conditions inherent in the programme. We use the reference model to analyse the activities of programme participants, and illustrate how these activities are palaeontologically authentic. Finally, we discuss our findings, examining the mechanism by which the specimens prompt scientific activities. We also discuss our discipline-based approach, and how it allows us to positively identify participants' activities as authentic. We conclude by discussing the implications of our findings.

  6. Divergent transcriptional activities determine limb identity

    PubMed Central

    Ouimette, Jean-François; Jolin, Marisol Lavertu; L'honoré, Aurore; Gifuni, Anthony; Drouin, Jacques

    2010-01-01

    Limbs develop using a common genetic programme despite widely differing morphologies. This programme is modulated by limb-restricted regulators such as hindlimb (HL) transcription factors Pitx1 and Tbx4 and the forelimb (FL) Tbx5. Both Tbx factors have been implicated in limb patterning and growth, but their relative activities and underlying mechanisms remain unclear. In this paper, we show that Tbx4 and Tbx5 harbour conserved and divergent transcriptional regulatory domains that account for their roles in limb development. In particular, both factors share an activator domain and the ability to stimulate limb growth. However, we find that Tbx4 is the primary effector of HL identity for both skeletal and muscle development; this activity relies on a repressor domain that is inactivated by a human TBX4 small-patella syndrome mutation. We propose that limb identity is largely achieved by default in FL, whereas a specific repressor activity unique to Tbx4 determines HL identity. PMID:20975709

    PubMed

    Shavlovsky, G M; Kashchenko, V E

    1975-01-01

    It is established that the main reason of the riboflavin kinase (RFK, EC 2.7.1.26) low specific activity in the cell-free extracts of the yeast Pichia guillermondii Wickerham ATCC 9058 is the presence of alkaline phosphatase (EC 3.1.3.1), effectively destructing flaven mononucleotide. By chromatography of the cell-free extracts of P. guillermondii on DEAE-Sephadex A-50, CM-Sphadex C-50, CM-cellulose, Sephadexes G-75 and G-100 RFK and alkaline phosphatase may be separated completely. Any of these procedures results in a several times increase of the RFK activity as compared with the initial preparation. One failed to obtain a similar effect by fractionation of the extracts with amminium sulphate and by hydroxylapatite chromatography. A simple method is developed for determining the activity of RFK in the cell-free extracts of yeast on the basis of negative adsorption of this enzyme on DEAE-Sephadex A-50. A selective inhibition of alkaline phosphatase by ions Be2+ and F- yields a less satisfactory result. The data are presented on the PFK activity of certain species of flavinogenic (Pichia guillermondii, Torulopsis camdida) and non-flavinogenic (Pichia ohmeri, Candida utilis, Saccharomyces cervisiae) yeast.

    Abrusán, György; Yant, Stephen R; Szilágyi, András; Marsh, Joseph A; Mátés, Lajos; Izsvák, Zsuzsanna; Barabás, Orsolya; Ivics, Zoltán

    2016-08-01

    Transposases are important tools in genome engineering, and there is considerable interest in engineering more efficient ones. Here, we seek to understand the factors determining their activity using the Sleeping Beauty transposase. Recent work suggests that protein coevolutionary information can be used to classify groups of physically connected, coevolving residues into elements called "sectors", which have proven useful for understanding the folding, allosteric interactions, and enzymatic activity of proteins. Using extensive mutagenesis data, protein modeling and analysis of folding energies, we show that (i) The Sleeping Beauty transposase contains two sectors, which span across conserved domains, and are enriched in DNA-binding residues, indicating that the DNA binding and endonuclease functions of the transposase coevolve; (ii) Sector residues are highly sensitive to mutations, and most mutations of these residues strongly reduce transposition rate; (iii) Mutations with a strong effect on free energy of folding in the DDE domain of the transposase significantly reduce transposition rate. (iv) Mutations that influence DNA and protein-protein interactions generally reduce transposition rate, although most hyperactive mutants are also located on the protein surface, including residues with protein-protein interactions. This suggests that hyperactivity results from the modification of protein interactions, rather than the stabilization of protein fold. PMID:27401040

  4. MiPLAN: a learner-centered model for bedside teaching in today's academic medical centers.

    PubMed

    Stickrath, Chad; Aagaard, Eva; Anderson, Mel

    2013-03-01

    Clinician educators and medical trainees face intense pressure to complete numerous patient care and teaching activities in a limited amount of time. To address the need for effective and efficient teaching methods for use in the inpatient setting, the authors used constructivist learning theory, the principles of adult learning, and their expertise as clinician educators to develop the MiPLAN model for bedside teaching. This three-part model is designed to enable clinical teachers to simultaneously provide care to patients while assessing learners, determining high-yield teaching topics, and providing feedback to learners.The "M" refers to a preparatory meeting between teacher and learners before engaging in patient care or educational activities. During this meeting, team members should become acquainted and the teacher should set goals and clarify expectations. The "i" refers to five behaviors for the teacher to adopt during learners' bedside presentations: introduction, in the moment, inspection, interruptions, and independent thought. "PLAN" is an algorithm to establish priorities for teaching subsequent to a learner's presentation: patient care, learners' questions, attending's agenda, and next steps.The authors suggest that the MiPLAN model can help clinical teachers gain more confidence in their ability to teach at the bedside and increase the frequency and quality of bedside teaching. They propose further research to assess the generalizability of this model to other institutions, settings, and specialties and to evaluate educational and patient outcomes. PMID:23348088

  18. Determination of beta activity in water

    USGS Publications Warehouse

    Barker, F.B.; Robinson, B.P.

    1963-01-01

    Many elements have one or more naturally radioactive isotopes, and several hundred other radionuclides have been produced artificially. Radioactive substances may be present in natural water as a result of geochemical processes or the release of radioactive waste and other nuclear debris to the environment. The Geological Survey has developed methods for measuring certain of these .radioactive substances in water. Radioactive substances often are present in water samples in microgram quantities or less. Therefore, precautions must be taken to prevent loss of material and to assure that the sample truly represents its source at the time of collection. Addition of acids, complexing agents, or stable isotopes often aids in preventing loss of radioactivity on container walls, on sediment, or on other solid materials in contact with the sample. The disintegration of radioactive atoms is a random process subject to established methods of statistical analysis. Because many water samples contain small amounts of radioactivity, low-level counting techniques must be used. The usual assumption that counting data follow a Gaussian distribution is invalid under these conditions, and statistical analyses must be based on the Poisson distribution. The gross beta activity in water samples is determined from the residue left after evaporation of the sample to dryness. Evaporation is accomplished first in a teflon dish, then the residue is transferred with distilled water to a counting planchet and again is reduced to dryness. The radioactivity on the planchet is measured with an anticoincidence-shielded, low-background, beta counter and is compared with measurements of a strontium-90-yttrium-90 standard prepared and measured in the same manner. Control charts are used to assure consistent operation of the counting instrument.

    NASA Astrophysics Data System (ADS)

    Quan, T. K.; Hunter, L.; Kluger-Bell, B.; Seagroves, S.

    2010-12-01

    The Professional Development Program (PDP) supports participants as they design inquiry activities that help learners improve their research process skills. These skills include the cognitive or reasoning skills that scientists and engineers use while doing research; for example, making a testable hypothesis, coordinating results from multiple experiments, or identifying and evaluating tradeoffs. Past work in the PDP indicated that additional support was needed to help participants design instructional activities that would teach these important skills. A new workshop was therefore developed for the 2009 PDP cycle, entitled "Improving Learners' Process Skills." In this workshop, participants worked in small groups to define specific science and engineering skills found in four past PDP activity designs. Participants distinguished between "simple tasks" and "authentic inquiry" activities that learners could perform as demonstration of the skill. Through this new workshop, participants were able to explicitly discuss ways in which individual process skills are unique or inter-related. In addition, by identifying a "simple task," participants were able to pinpoint areas in which their own designs could be improved to better focus on authentic inquiry tasks. In 2010, the workshop was slightly modified to help participants reconnect the research process skills with the activity content. In addition, the idea of using generic and context-specific scaffolds was also introduced. To make the participants feel like they were contributing to the PDP community, four activity designs actively being worked on in the 2010 cycle were used. Based on participant feedback, this "Improving Learners' Process Skills" workshop should be strongly considered for future returning participants.

    2015-08-25

    Constituents of living or synthetic active matter have access to a local energy supply that serves to keep the system out of thermal equilibrium. The statistical properties of such fluctuating active systems differ from those of their equilibrium counterparts. Using the actin filament gliding assay as a model, we studied how nonthermal distributions emerge in active matter. We found that the basic mechanism involves the interplay between local and random injection of energy, acting as an analog of a thermal heat bath, and nonequilibrium energy dissipation processes associated with sudden jump-like changes in the system's dynamic variables. We show here how such a mechanism leads to a nonthermal distribution of filament curvatures with a non-Gaussian shape. The experimental curvature statistics and filament relaxation dynamics are reproduced quantitatively by stochastic computer simulations and a simple kinetic model. PMID:26261319

Currently, to estimate the effects of those conditions on other targets requires either strong modeling assumptions (e.g. similarities among targets) or separate screens. Ideally, data-driven experimentation could be used to learn accurate models for many conditions and targets without doing all possible experiments. We have previously described an active machine learning algorithm that can iteratively choose small sets of experiments to learn models of multiple effects. We now show that, with no prior knowledge and with liquid handling robotics and automated microscopy under its control, this learner accurately learned the effects of 48 chemical compounds on the subcellular localization of 48 proteins while performing only 29% of all possible experiments. The results represent the first practical demonstration of the utility of active learning-driven biological experimentation in which the set of possible phenotypes is unknown in advance.

  18. The adult learner: is it necessary to understand for teaching in anesthesiology.

    Gaiser, Robert R

    2010-01-01

    Educators came to realize what internists and pediatricians have known all along: adults and children are not the same. They differ in physiology, pharmacology, and learning. To approach teaching of the adult learner as one would a child is likely to fail. To effectively design and execute a curriculum for the adult, the teacher must consider the role of personal experience, learning preparedness, learning orientation, and motivation to learn. Although these principles may seem novel, they represent good judgment when teaching the adult. The key factor for the educator is to determine the needs of the adult (which is typically based upon personal experience) and then design and implement a curriculum based upon these needs. This approach is backward from the approach used in children in which the curriculum is established without any input from the learner. One other means to improve success is to foster personal reflection upon the teaching by the adult learner. This reflection may develop from carefully phrased questions, from activities in applying the knowledge, or from within the learner. By helping the learner to reflect, the true goals of the teaching may be achieved and the teacher is rewarded by having a more knowledgeable provider, who is able to use and to question the new knowledge. The cycle of adult learning is completed but also starts again. PMID:20616634

  19. Learner-Centered Teaching in Nonmajors Introductory Biology: The Impact of Giving Students Choices

    Learner-centered teaching represents more than creating a course where students are actively engaged. Rather it is articulated by a shift in the balance of power, function of content, role of the instructor, purpose of assessment, and/or responsibility for learning in a course. To make the learning environment in a large-enrollment nonmajors Biology course more learner-centered, students were given the responsibility to: 1) select course topics, 2) determine the types and weights of course assignments used to assess learning, and 3) individually decide, prior to being assigned work, the weight of exams and projects. Combined survey results from two learner-centered sections of the course (n = 137) indicate that a majority of the students found that choosing the topics enhanced their learning of course material. Students also reported that they put more effort into the parts of the course that they had weighted more heavily. In addition, results support that students are reflective of the learner-centered environment, confident in their ability to learn biological topics and more interested in biology than they thought they would be. Finally, course averages from the learner-centered courses were significantly higher than course grades from instructor-centered versions of the course. PMID:23653800

  6. Developing the master learner: applying learning theory to the learner, the teacher, and the learning environment.

    PubMed

    Schumacher, Daniel J; Englander, Robert; Carraccio, Carol

    2013-11-01

    As a result of the paradigm shift to a competency-based framework, both self-directed lifelong learning and learner-centeredness have become essential tenets of medical education. In the competency-based framework, learners drive their own educational process, and both learners and teachers share the responsibility for the path and content of learning. This learner-centered emphasis requires each physician to develop and maintain lifelong learning skills, which the authors propose culminate in becoming a "master leaner." To better understand the development of these skills and the attainment of that goal, the authors explore how learning theories inform the development of master learners and how to translate these theories into practical strategies for the learner, the teacher, and the learning environment so as to optimize this development.The authors begin by exploring self-determination theory, which lays the groundwork for understanding the motivation to learn. They next consider the theories of cognitive load and situated cognition, which inform the optimal context and environment for learning. Building from this foundation, the authors consider key educational theories that affect learners' abilities to serve as primary drivers of their learning, including self-directed learning (SDL); the self-assessment skills necessary for SDL; factors affecting self-assessment (self-concept, self-efficacy, illusory superiority, gap filling); and ways to mitigate the inaccuracies of self-assessment (reflection, self-monitoring, external information seeking, and self-directed assessment seeking).For each theory, they suggest practical action steps for the learner, the teacher, and the learning environment in an effort to provide a road map for developing master learners.

  9. Gender agreement violations modulate beta oscillatory dynamics during sentence comprehension: A comparison of second language learners and native speakers.

    PubMed

    2016-08-01

    For native speakers, many studies suggest a link between oscillatory neural activity in the beta frequency range and syntactic processing. For late second language (L2) learners on the other hand, the extent to which the neural architecture supporting syntactic processing is similar to or different from that of native speakers is still unclear. In a series of four experiments, we used electroencephalography to investigate the link between beta oscillatory activity and the processing of grammatical gender agreement in Dutch determiner-noun pairs, for Dutch native speakers, and for German L2 learners of Dutch. In Experiment 1 we show that for native speakers, grammatical gender agreement violations are yet another among many syntactic factors that modulate beta oscillatory activity during sentence comprehension. Beta power is higher for grammatically acceptable target words than for those that mismatch in grammatical gender with their preceding determiner. In Experiment 2 we observed no such beta modulations for L2 learners, irrespective of whether trials were sorted according to objective or subjective syntactic correctness. Experiment 3 ruled out that the absence of a beta effect for the L2 learners in Experiment 2 was due to repetition of the target nouns in objectively correct and incorrect determiner-noun pairs. Finally, Experiment 4 showed that when L2 learners are required to explicitly focus on grammatical information, they show modulations of beta oscillatory activity, comparable to those of native speakers, but only when trials are sorted according to participants' idiosyncratic lexical representations of the grammatical gender of target nouns. Together, these findings suggest that beta power in L2 learners is sensitive to violations of grammatical gender agreement, but only when the importance of grammatical information is highlighted, and only when participants' subjective lexical representations are taken into account.

    2005-12-01

    The purpose of this study was to examine the interactions of eighth grade English Language Learners in an inclusive science classroom. There is a paucity of research in this area. Central to this study was the students' perceptions and interactions with five different science curriculum features; teacher presentation and guided notes, worksheets, homework, labs, and practice and review activities. The student participants were English Language Learners from two language proficiency levels and the teacher was a provisionally licensed first year science teacher. The aggregate data included individual interviews with the students and teacher, classroom observations, and the collection of classroom artifacts. The findings revealed: (a) students' comprehension of the material was inconsistent throughout all of the curriculum features and differences were observed not only between but also within the two proficiency levels; (b) classroom organizational issues created challenges for both the teacher and the students; (c) off task behavior was most prevalent during the teacher's one-to-one instruction and interfered with learning; (d) differences between levels of language proficiency were observed among students who preferred to work independently and were comfortable asking the teacher for assistance and the students who preferred working with and receiving assistance from peers; and (e) language proficiency rather than cultural differences appeared to be the greatest barrier to classroom success. Overall, English language proficiency was a crucial determinant in the English Language Learners success in the inclusive classroom. Additionally, implications suggest that a limited teaching skill set could adversely affect the success of students in inclusive classrooms.

    2011-01-01

    The purpose of the study was to compare the extent to which the different teaching approaches applied in the Baccalaureus Curationis programme adequately prepare graduating learners for professional competence. The research methodology was a quantitative approach, based on descriptive research, with a clinical competence development model to guide the data collection procedure. The target population of the study included a sample of 250 learners in the four-year B.Cur programme, that extended from first-to-fourth-year. Stratified random sampling was applied to select the sample learners for this research and data were collected by means of a five-point Likert scale questionnaire. Data were organised and managed using the SAS statistical software package. Descriptive statistics were gathered with measures of central tendency and dispersion included, and their findings were illustrated on descriptive tables. A correlation technique was applied to determine the effects of the independent variable on the dependent variable.The results of the study indicated that progression in competence did not occur as learners progressed through higher levels of their training, except during the third-year of study. However, the study's results confirmed the strengths of the Case-based clinical reasoning approach to teaching and learning. This approach is able to combine the strengths of the traditional methods, which dealt with large class sizes and that had a focus on learner centred learning, with a focus on clinical practice. This approach provides realistic opportunities for learners to experiment with solutions to dilemmas encountered in real life situations, from the protected and safe environment of the classroom. The first-year learners who were observed in this study, who although novices, were exposed to Case-based teaching approaches and showed more self-perceived competence than learners in later years. This occurred in spite of the limited exposure of the first

  4. Determinants affecting physical activity levels in animal models

    Tou, Janet C L.; Wade, Charles E.

    2002-01-01

    Weight control is dependent on energy balance. Reduced energy expenditure (EE) associated with decreased physical activity is suggested to be a major underlying cause in the increasing prevalence of weight gain and obesity. Therefore, a better understanding of the biological determinants involved in the regulation of physical activity is essential. To facilitate interpretation in humans, it is helpful to consider the evidence from animal studies. This review focuses on animal studies examining the biological determinants influencing activity and potential implications to human. It appears that physical activity is influenced by a number of parameters. However, regardless of the parameter involved, body weight appears to play an underlying role in the regulation of activity. Furthermore, the regulation of activity associated with body weight appears to occur only after the animal achieves a critical weight. This suggests that activity levels are a consequence rather than a contributor to weight control. However, the existence of an inverse weight-activity relationship remains inconclusive. Confounding the results are the multifactorial nature of physical activity and the lack of appropriate measuring devices. Furthermore, many determinants of body weight are closely interlocked, making it difficult to determine whether a single, combination, or interaction of factors is important for the regulation of activity. For example, diet-induced obesity, aging, lesions to the ventral medial hypothalamus, and genetics all produce hypoactivity. Providing a better understanding of the biological determinants involved in the regulation of activity has important implications for the development of strategies for the prevention of weight gain leading to obesity and subsequent morbidity and mortality in the human population.

    2015-01-01

    A direct and continuous approach to determine simultaneously protein and phosphate concentrations in cells and kinetics of phosphate release from physiological substrates by cells without any labeling has been developed. Among the enzymes having a phosphatase activity, tissue non-specific alkaline phosphatase (TNAP) performs indispensable, multiple functions in humans. It is expressed in numerous tissues with high levels detected in bones, liver and neurons. It is absolutely required for bone mineralization and also necessary for neurotransmitter synthesis. We provided the proof of concept that infrared spectroscopy is a reliable assay to determine a phosphatase activity in the osteoblasts. For the first time, an overall specific phosphatase activity in cells was determined in a single step by measuring simultaneously protein and substrate concentrations. We found specific activities in osteoblast like cells amounting to 116 ± 13 nmol min(-1) mg(-1) for PPi, to 56 ± 11 nmol min(-1) mg(-1) for AMP, to 79 ± 23 nmol min(-1) mg(-1) for beta-glycerophosphate and to 73 ± 15 nmol min(-1) mg(-1) for 1-alpha-D glucose phosphate. The assay was also effective to monitor phosphatase activity in primary osteoblasts and in matrix vesicles. The use of levamisole--a TNAP inhibitor--served to demonstrate that a part of the phosphatase activity originated from this enzyme. An IC50 value of 1.16 ± 0.03 mM was obtained for the inhibition of phosphatase activity of levamisole in osteoblast like cells. The infrared assay could be extended to determine any type of phosphatase activity in other cells. It may serve as a metabolomic tool to monitor an overall phosphatase activity including acid phosphatases or other related enzymes. PMID:25785438

    Sak-Bosnar, Milan; Sakač, Nikola

    2012-11-15

    A novel method for the determination of diastase activity is reported. The method is based on a direct potentiometric measurement of triiodide ion that is released when a starch-triiodide complex is hydrolysed by honey diastase. The increase of free triiodide ion concentration in a sample is found to be directly proportional to the diastase activity of the sample. A response mechanism of the platinum redox electrode is proposed, allowing a calculation of the diastase activity factor (F). The sensor and analyte parameters, including F, were obtained by least squares fitting of potentiometric data using the optimisation function of the Solver add-in of Microsoft Excel. The values of F obtained by the new direct potentiometric method were compared with those obtained using the standard Phadebas method (DN values), and the two values were found to agree within experimental error. Finally, the diastase activity of nine varieties of honey was determined using the novel method developed here. PMID:22868165

    Cheah, Yong Kang; Poh, Bee Koon

    2014-01-01

    Objectives In light of the importance of physical activity, the aim of the present study is to examine the factors affecting participation in physical activity among adults in Malaysia. Methods A logistic regression model and the Third National Health and Morbidity Survey consisting of 30,992 respondents were used. Results Age, income, gender, education, marital status, region, house locality, job characteristics, and medical conditions are significantly associated with participation in physical activity. In particular, old individuals, high income earners, females, the well-educated, widowed or divorced individuals, East Malaysians, urban dwellers, the unemployed, and individuals who are not diagnosed with hypercholesterolemia are less likely to be physically active than others. Conclusion Because sociodemographic and health factors play an important role in determining physical activity, the government should take them into account when formulating policy. PMID:24955308

    1979-01-01

    The authors described a method for determination of tissue renin activity with heterologous substrate. The preparation of the substrate was performed at several stages: salting with amonium sulfate; dialisis of the precipitate till complete separation of amonium sulfate molecules; distruction of angiotensinases by interchangeble souring and alcalization of the medium; lyophylization of the pure substrate. The obtained renin-substrate was preserved in ampules and its usage had a series of advantages--duration, economic, a possibility for standartization of the determination, etc., which were described in details in the article. The described in details also the quantitative determination of the renin activity in the tissues (renal and cerebral) with the help of the obtained substrate as the moments, modiied by the authors, were indicated.

    PubMed

    Cansino, Kenyi; Gálvez, Harold

    2014-01-01

    This document attempts to establish the determinants of participation in physical activity in Peru using the economic structure presented by Cawley and a participation choice model proposed by Humphreys and Ruseski. Through the National Survey of Nutritional, Biochemical, Socioeconomic and Cultural Indicators related to Chronic-Degenerative Diseases in 2006, a logistic model was estimated through which an observation was made: more educated individuals are more likely to participate in physical activities. Also, characteristics like socioeconomic status and employment decrease the likelihood of participating in physical activities due to a higher opportunity cost. In the same way, it was observed that adults are less likely to participate in physical activities due to biological characteristics related to age. PMID:24718541

  14. Molecular Determinants of GS-9620-Dependent TLR7 Activation

    2016-01-01

    GS-9620 is an orally administered agonist of Toll-like receptor (TLR)7 currently being evaluated in clinical studies for the treatment of chronic HBV and HIV patients. GS-9620 has shown antiviral efficacy in preclinical models of chronic hepadnavirus infection in woodchuck as well as chimpanzee. However, the molecular determinants of GS-9620-dependent activation of TLR7 are not well defined. The studies presented here elucidate GS-9620 subcellular distribution and characterize its molecular interactions with human TLR7 using structure-guided mutational analysis. Based on our results we present a molecular model of TLR7 bound to GS-9620. We also determine that several coding SNPs had no effect on GS-9620-dependent TLR7 activation. In addition, our studies provide evidence that TLR7 exists in a ligand-independent oligomeric state and that, TLR7 activation by GS-9620 is likely associated with compound-induced conformational changes. Finally, we demonstrate that activation of NF-κB and Akt pathways in primary plasmacytoid dendritic cells occur as immediate downstream cellular responses to GS-9620 stimulation. The data presented here further our understanding of the molecular parameters governing TLR7 activation by GS-9620, and more generally by nucleos/tide-related ligands. PMID:26784926

  15. Surface diffusion activation energy determination using ion beam microtexturing

    NASA Technical Reports Server (NTRS)

    Rossnagel, S. M.; Robinson, R. S.

    1982-01-01

    The activation energy for impurity atom (adatom) surface diffusion can be determined from the temperature dependence of the spacing of sputter cones. These cones are formed on the surface during sputtering while simultaneously adding impurities. The impurities form clusters by means of surface diffusion, and these clusters in turn initiate cone formation. Values are given for the surface diffusion activation energies for various materials on polycrystalline Cu, Al, Pb, Au, and Ni. The values for different impurity species on each of these substrates are approximately independent of impurity species within the experimental uncertainty, suggesting the absence of strong chemical bonding effects on the diffusion.

  2. Determination Of The Activity Space By The Stereometric Method

    NASA Astrophysics Data System (ADS)

    Deloison, Y.; Crete, N.; Mollard, R.

    1980-07-01

    To determine the activity space of a sitting subject, it is necessary to go beyond the mere statistical description of morphology and the knowledge of the displacement volume. An anlysis of the positions or variations of the positions of the diverse segmental elements (arms, hands, lower limbs, etc...) in the course of a given activity is required. Of the various methods used to locate quickly and accurately the spatial positions of anatomical points, stereometry makes it possible to plot the three-dimensional coordinates of any point in space in relation to a fixed trirectangle frame of reference determined by the stereome-tric measuring device. Thus, regardless of the orientation and posture of the subject, his segmental elements can be easily pin-pointed, throughout the experiment, within the space they occupy. Using this method, it is possible for a sample of operators seated at an operation station and applying either manual controls or pedals and belonging to a population statistically defined from the data collected and the analyses produced by the anthropometric study to determine a contour line of reach capability marking out the usable working space and to know, within this working space, a contour line of preferential activity that is limited, in space, by the whole range of optimal reach capability of all the subjects.

  3. Social and proximate determinants of sexual activity in rural Nigeria.

    PubMed

    Barden-O'Fallon, Janine; Tsui, Amy; Adewuyi, Alfred

    2003-10-01

    This study analyses the social, physiological and motivational determinants of sexual activity for 644 married women in rural areas of Osun State, Nigeria. The data come from the Fertility Awareness and Pregnancy Avoidance study conducted in 1993-94. Sexual activity is measured by three continuous variables: weekly frequency of (1) total sexual activity, (2) coital-only sex and (3) both coital/non-coital sex. Analyses of variance were performed to test the difference in group means between the predictor variables and measures of sexual activity. Ordinary least squares regression analyses were then performed for the three dependent variables. Two models are used: the first contains only those variables associated with an individual's demographic, social and economic status, and the second adds predictor variables associated with motivational and physiological factors. Results show that while many socioeconomic variables by themselves are significantly associated with sexual activity measures, the addition of physiological and motivational variables weakens their effects and lessens their original statistical significance. Additionally, the socioeconomic and demographic factors associated with frequency of sexual activity are not necessarily the same ones significantly associated with coital-only or combined coital/non-coital sex. While other studies have tended to focus either on socioeconomic or physiological factors, the joint examination of both types of influences seems to indicate that the latter have more proximate effects on the frequency of both coital and non-coital sexual activity of married women in this population. Contraceptive protection is shown to be highly positively associated with all three of the sexual activity measures, empirically confirming the important relationship between contraception and both coital and non-coital forms of sexual activity.

    2012-03-28

    The principle virulence factors in Clostridium difficile pathogenesis are TcdA and TcdB, homologous glucosyltransferases capable of inactivating small GTPases within the host cell. We present crystal structures of the TcdA glucosyltransferase domain in the presence and absence of the co-substrate UDP-glucose. Although the enzymatic core is similar to that of TcdB, the proposed GTPase-binding surface differs significantly. We show that TcdA is comparable with TcdB in its modification of Rho family substrates and that, unlike TcdB, TcdA is also capable of modifying Rap family GTPases both in vitro and in cells. The glucosyltransferase activities of both toxins are reduced in the context of the holotoxin but can be restored with autoproteolytic activation and glucosyltransferase domain release. These studies highlight the importance of cellular activation in determining the array of substrates available to the toxins once delivered into the cell.

  6. Determination of fungal activity in modified wood by means of micro-calorimetry and determination of total esterase activity

    PubMed Central

    Verma, Pradeep; Dyckmans, Jens; Militz, Holger

    2008-01-01

    Beech and pine wood blocks were treated with 1,3-dimethylol-4,5-dihydroxyethylen urea (DMDHEU) to increasing weight percent gains (WPG). The resistance of the treated specimens against Trametes versicolor and Coniophora puteana, determined as mass loss, increased with increasing WPG of DMDHEU. Metabolic activity of the fungi in the wood blocks was assessed as total esterase activity (TEA) based on the hydrolysis of fluorescein diacetate and as heat or energy production determined by isothermal micro-calorimetry. Both methods revealed that the fungal activity was related with the WPG and the mass loss caused by the fungi. Still, fungal activity was detected even in wood blocks of the highest WPG and showed that the treatment was not toxic to the fungi. Energy production showed a higher consistency with the mass loss after decay than TEA; higher mass loss was more stringently reflected by higher heat production rate. Heat production did not proceed linearly, possibly due to the inhibition of fungal activity by an excess of carbon dioxide. PMID:18542949

Participants The sample included 312 adult patients attending Ambo Hospital. The main outcome measure was presence of active pulmonary tuberculosis (TB). Explanatory measures Age, gender, occupation, educational status, marital status, place of residence, patient history of TB, family history of TB, human immunodeficiency virus (HIV) infection, smoking, alcohol intake, khat chewing, body mass index (BMI), employment, diabetes, history of asthma, previous history of worm infestation, history of hospitalisation, number of adults living in the household (HH), person per room, housing condition. Results A total of 312 study participants, including 104 active pulmonary tuberculosis (PTB) cases (cases) and 208 non-active PTB cases (controls), were recruited for the present study. Having one or more family member with a history of TB (OR = 4.4; 95% CI: 1.50–12.90), marital status (OR = 7.6; 95% CI: 2.2–12.6), male gender (OR = 3.2; 95% CI: 1.4–7), rural residence (OR = 3.3; P = 0.012), being a current or past smoker (OR = 2.8; 95% CI: 1.1–7.2), BMI < 18.5 (OR = 2.1; 95% CI: 1.03–4.2), HIV infection (OR = 8.8; 95% CI: 2.4–23.8) and a history of worm infestation (OR = 6.4; 95% CI: 2.6–15.4) remained significant independent host-related factors for active PTB. Conclusion Patients who came from a compound with more than two HHs were more likely to develop active PTB than those who came from a compound with only one HH. Those who lived in houses with no windows were more likely to develop active PTB than those who lived in houses with one or more windows, had a family history of TB, lived in rural areas. Sex of the patient was a predicting factor. Not being the owner of the house was

  9. Rapid optical determination of β-lactamase and antibiotic activity

    2014-01-01

    Background The absence of rapid tests evaluating antibiotic susceptibility results in the empirical prescription of antibiotics. This can lead to treatment failures due to escalating antibiotic resistance, and also furthers the emergence of drug-resistant bacteria. This study reports a rapid optical method to detect β-lactamase and thereby assess activity of β-lactam antibiotics, which could provide an approach for targeted prescription of antibiotics. The methodology is centred on a fluorescence quenching based probe (β-LEAF – β-Lactamase Enzyme Activated Fluorophore) that mimics the structure of β-lactam antibiotics. Results The β-LEAF assay was performed for rapid determination of β-lactamase production and activity of β-lactam antibiotic (cefazolin) on a panel of Staphylococcus aureus ATCC strains and clinical isolates. Four of the clinical isolates were determined to be lactamase producers, with the capacity to inactivate cefazolin, out of the twenty-five isolates tested. These results were compared against gold standard methods, nitrocefin disk test for β-lactamase detection and disk diffusion for antibiotic susceptibility, showing results to be largely consistent. Furthermore, in the sub-set of β-lactamase producers, it was demonstrated and validated that multiple antibiotics (cefazolin, cefoxitin, cefepime) could be assessed simultaneously to predict the antibiotic that would be most active for a given bacterial isolate. Conclusions The study establishes the rapid β-LEAF assay for β-lactamase detection and prediction of antibiotic activity using S. aureus clinical isolates. Although the focus in the current study is β-lactamase-based resistance, the overall approach represents a broad diagnostic platform. In the long-term, these studies form the basis for the development of assays utilizing a broader variety of targets, pathogens and drugs. PMID:24708478

  10. Determination of phosphodiesterase I activity in human blood serum.

    Phosphodiesterase I (EC 3.1.4.1) activity was detected in normal human blood serum. The enzyme is stable at laboratory temperature for three days, but is inactivated at pH less than 7. The pH for optimum activity increases with the substrate concentration (under the conditions used, from pH 9.0 to 10.2) and, conversely, the Km increases with pH and buffer concentration. The enzyme is inhibited by ethylenediaminetetraacetate but not by phosphate (0.1 mol/liter). We developed a simple quantitative method for its determination, based on hydrolysis of the p-nitrophenyl ester of thymidine 5'-monophosphate and subsequent measurement of the liberated p-nitrophenol at 400 nm in NaOH (0.1 mol/liter). Normal values (mean +/- 2 SD) were determined to be 33 +/- 6.4 U/liter. Preliminary studies indicate that phosphodiesterase I activity is greater than normal in serum of patients with necrotic changes in the liver or kidney or in cases of breast cancer, but not in that of patients with myocardial infarction, bone cancer, lung cancer, or chronic liver cirrhosis.

    The plant kingdom might yield an effective antifertility drug. A Mentha arvensis L. (Labiatae) fraction with uterotonic activity was isolated, and was found to be active on the nonpregnant as well as the pregnant rat uterus. According to folklore medicine, the Mexican plant Montanoa tomentosa Cerv. (zoapatle) possesses antifertility activity in women. The effect of various isolated preparations from this plant on early pregnancy were investigated in serveral rodent species including the mouse, rat hamster, and guinea pig. It was concluded that zoapatle plant extracts possess unique antifertility activity. Lin-Hsim and coworkers isolated fractions from Aristolochia molissima Hanceith contrceptive activity in female mice. Saponins of some plants were used in contraceptive formulations either as foaming agents or as spermicidal substances. Elbary and Nour investigated the spermicidal effects of saponins isolated from the following plants: Gypsophila paniculata L., Saponaria officinalis L., Enterolobium cyclocarpum, Griseb., Terminalia horrida Steud., Melilotus sicula Vitm., and Ruscus hypoglossum L. All of the saponins tested possessed spermicidal activity. Jain and coworkers isolated 2 new saponins in Pittosporum nilghrense with spermicidal effects. In this paper we have determined the spermicidal activity of saponins isolated from some Yugoslav plants, which in that aspect have not been investigated. The results are illustrated in the table. They show that all of the saponins tested were spermicidal in dependence on their nature. Saponins of Primula vulgaris Huds. and Cyclamen persicum Mill. immobilized human spermatozoa within a period of 20 s at a dilution 1:1000. Saponin of Gypsophila paniculata L. was spermicidal at dilution 1:20. These findings show that saponins isolated from some Yugoslav plants may be useful spermicides of natural origin. PMID:4080814

    The ability of living cells to maintain an inheritable memory of their gene-expression state is key to cellular differentiation. Bacterial lysogeny serves as a simple paradigm for long-term cellular memory. In this study, we address the following question: in the absence of external perturbation, how long will a cell stay in the lysogenic state before spontaneously switching away from that state? We show by direct measurement that lysogen stability exhibits a simple exponential dependence on the frequency of activity bursts from the fate-determining gene, cI. We quantify these gene-activity bursts using single-molecule-resolution mRNA measurements in individual cells, analyzed using a stochastic mathematical model of the gene-network kinetics. The quantitative relation between stability and gene activity is independent of the fine details of gene regulation, suggesting that a quantitative prediction of cell-state stability may also be possible in more complex systems.

    An analytical procedure has been developed for the determination of the 18 PCB congeners which are inducers of methylcholanthrene-like mixed function oxidase activity in animals and include the most toxic PCBs. Determinations of the toxic PCB congeners in samples of eggs of predatory fish and piscivorous birds of the Great Lakes and in Aroclor mixtures demonstrate that the apparent toxic potency of PCB residues in these samples is dominated by two congeners, 3,3′,4,4′,5- and 2,3,3′,4,4′-pentachlorobiphenyl. Furthermore, the analyses demonstrate that the potential toxicity of PCB residues can increase 5 to 10 fold as they reach upper levels of aquatic food chains and most often exceed the potential toxicity of chlorinated dibenzodioxins and furans in higher animals even in environments highly contaminated by the latter compounds.

    1996-01-01

    Reversed siderophores (RSFs) are artificial hydroxamate-based iron chelators designed after the natural siderophore ferrichrome. The modular molecular design of RSF derivatives allowed the synthesis of various congeners with controlled iron-binding capacities and partition coefficients. These two physicochemical properties were assessed by a novel fluorescent method and were found to be the major determinants of RSF permeation across erythrocyte membranes and scavenging of compartmentalized iron. The partition coefficient apparently conferred upon RSFs two major features: (i) the ability to rapidly access iron pools of in vitro-grown Plasmodium falciparum at all developmental stages and to mobilize intracellular iron and transfer it to the medium and (ii) the ability to suppress parasite growth at all developmental stages. These features of RSFs were assessed by quantitative determination of the structure-activity relationships of the biological activities and partition coefficients spanning a wide range of values. The most effective RSF containing the aromatic group of phenylalanine (RSFm2phe) showed 50% inhibitory concentration of 0.60 +/- 0.03 nmol/ml in a 48-h test and a 2-h onset of inhibition of ring development at 5 nmol/ml. The lipophilic compound RSFm2phe and the lipophilic and esterase-cleavable compound RSFm2pee inhibited parasite growth at all developmental stages whether inhibition was assessed in a continuous mode or after discontinuing drug administration. The antimalarial effects of RSFm2phe and cleavable RSFm2pee were potentiated in the presence of desferrioxamine (DFO) at concentrations at which DFO alone had no effect on parasite growth. These studies provide experimental evidence indicating that the effective and persistent antimalarial actions of RSFs are associated with drug access to infected cells and scavenging of iron from intracellular parasites. Moreover, the optimal antimalarial actions of RSFs are apparently also determined by improved

    2016-01-01

    While MOOCs offer educational data on a new scale, many educators find great potential of the big data including detailed activity records of every learner. A learner's behavior such as if a learner will drop out from the course can be predicted. How to provide an effective, economical, and scalable method to detect cheating on tests such as surrogate exam-taker is a challenging problem. In this paper, we present a grade predicting method that uses student activity features to predict whether a learner may get a certification if he/she takes a test. The method consists of two-step classifications: motivation classification (MC) and grade classification (GC). The MC divides all learners into three groups including certification earning, video watching, and course sampling. The GC then predicts a certification earning learner may or may not obtain a certification. Our experiment shows that the proposed method can fit the classification model at a fine scale and it is possible to find a surrogate exam-taker. PMID:26884747

    Ebert-May, Diane

    2010-01-01

    We determined short- and long-term correlates of a revised introductory biology curriculum on understanding of biology as a process of inquiry and learning of content. In the original curriculum students completed two traditional lecture-based introductory courses. In the revised curriculum students completed two new learner-centered, inquiry-based courses. The new courses differed significantly from those of the original curriculum through emphases on critical thinking, collaborative work, and/or inquiry-based activities. Assessments were administered to compare student understanding of the process of biological science and content knowledge in the two curricula. More seniors who completed the revised curriculum had high-level profiles on the Views About Science Survey for Biology compared with seniors who completed the original curriculum. Also as seniors, students who completed the revised curriculum scored higher on the standardized Biology Field Test. Our results showed that an intense inquiry-based learner-centered learning experience early in the biology curriculum was associated with long-term improvements in learning. We propose that students learned to learn science in the new courses which, in turn, influenced their learning in subsequent courses. Studies that determine causal effects of learner-centered inquiry-based approaches, rather than correlative relationships, are needed to test our proposed explanation. PMID:21123693

    2016-08-17

    Mechanochemical reactions often result in 100% yields of single products, making purifying procedures obsolete. Mechanochemistry is also a sustainable and eco-friendly method. The ever increasing interest in this method is contrasted by a lack in mechanistic understanding of the mechanochemical reactivity and selectivity. Recent in situ investigations provided direct insight into formation pathways. However, the currently available theories do not predict temperature T as an influential factor. Here, we report the first determination of an apparent activation energy for a mechanochemical reaction. In a temperature-dependent in situ study the cocrystallisation of ibuprofen and nicotinamide was investigated as a model system. These experiments provide a pivotal step towards a comprehensive understanding of milling reaction mechanisms. PMID:27498986

    The objective was to identify determinants of uptake and maintenance of active school travel (AST) over 4 years in children aged 9 at baseline. Data from wave 1 (n=8502) and 2 (n=7479) of the Growing Up in Ireland study were analysed. At 9- and 13-years 25% and 20% engaged in AST. Children were more likely to maintain or take-up AST if they lived in an urban area. Change in distance to school influenced both maintenance and adoption of AST, with a negative impact seen for increased distance between 9 and 13 years and a positive impact seen for decreased distance. Some factors which predict uptake and maintenance of AST are modifiable and can inform intervention development. PMID:27160529

    2012-02-01

    This study investigated which aspects of the individuals' activity behavior determine the physical activity level (PAL). Habitual physical activity of 20 Dutch adults (age: 26-60 years, body mass index: 24.5 ± 2.7 kg/m(2)) was measured using a tri-axial accelerometer. Accelerometer output was used to identify the engagement in different types of daily activities with a classification tree algorithm. Activity behavior was described by the daily duration of sleeping, sedentary behavior (lying, sitting, and standing), walking, running, bicycling, and generic standing activities. Simultaneously, the total energy expenditure (TEE) was measured using doubly labeled water. PAL was calculated as TEE divided by sleeping metabolic rate. PAL was significantly associated (P<0.05) with sedentary time (R=-0.72), and the duration of walking (R=0.49), bicycling (R=0.77), and active standing (R=0.62). A negative association was observed between sedentary time and the duration of active standing (R=-0.87; P<0.001). A multiple-linear regression analysis showed that 75% of the variance in PAL could be predicted by the duration of bicycling (Partial R(2) =59%; P<0.01), walking (Partial R(2) =9%; P<0.05) and being sedentary (Partial R(2) =7%; P<0.05). In conclusion, there is objective evidence that sedentary time and activities related to transportation and commuting, such as walking and bicycling, contribute significantly to the average PAL.

    2016-04-01

    We developed a tool for automatic determination of first arrivals in active seismic data based on an approach, that utilises higher order statistics (HOS) and the Akaike information criterion (AIC), commonly used in seismology, but not in active seismics. Automatic picking is highly desirable in active seismics as the number of data provided by large seismic arrays rapidly exceeds of what an analyst can evaluate in a reasonable amount of time. To bring the functionality of automatic phase picking into the context of active data, the software package ActiveSeismoPick3D was developed in Python. It uses a modified algorithm for the determination of first arrivals which searches for the HOS maximum in unfiltered data. Additionally, it offers tools for manual quality control and postprocessing, e.g. various visualisation and repicking functionalities. For flexibility, the tool also includes methods for the preparation of geometry information of large seismic arrays and improved interfaces to the Fast Marching Tomography Package (FMTOMO), which can be used for the prediction of travel times and inversion for subsurface properties. Output files are generated in the VTK format, allowing the 3D visualization of e.g. the inversion results. As a test case, a data set consisting of 9216 traces from 64 shots was gathered, recorded at 144 receivers deployed in a regular 2D array of a size of 100 x 100 m. ActiveSeismoPick3D automatically checks the determined first arrivals by a dynamic signal to noise ratio threshold. From the data a 3D model of the subsurface was generated using the export functionality of the package and FMTOMO.

  3. Three determinants in ezrin are responsible for cell extension activity.

    PubMed Central

    1997-01-01

    The ERM proteins--ezrin, radixin, and moesin--are key players in membrane-cytoskeleton interactions. In insect cells infected with recombinant baculoviruses, amino acids 1-115 of ezrin were shown to inhibit an actin- and tubulin-dependent cell-extension activity located in ezrin C-terminal domain (ezrin310-586), whereas full-length ezrin1-586 did not induce any morphological change. To refine the mapping of functional domains of ezrin, 30 additional constructs were overexpressed in Sf9 cells, and the resulting effect of each was qualitatively and semiquantitatively compared. The removal of amino acids 13-30 was sufficient to release a cell-extension phenotype. This effect was abrogated if the 21 distal-most C-terminal amino acids were subsequently deleted (ezrin31-565), confirming the existence of a head-to-tail regulation in the whole molecule. Surprisingly, the deletion in full-length ezrin of the same 21 amino acids provided strong cell-extension competence to ezrin1-565, and this property was recovered in N-terminal constructs as short as ezrin1-310. Within ezrin1-310, amino acid sequences 13-30 and 281-310 were important determinants and acted in cooperation to induce cytoskeleton mobilization. In addition, these same residues are part of a new actin-binding site characterized in vitro in ezrin N-terminal domain. Images PMID:9285824

  2. Chinese English Learners' Strategic Competence.

    PubMed

    Wang, Dianjian; Lai, Hongling; Leslie, Michael

    2015-12-01

    The present study aims to investigate Chinese English learners' ability to use communication strategies (CSs). The subjects are put in a relatively real English referential communication setting and the analyses of the research data show that Chinese English learners, when encountering problems in foreign language (FL) communication, are characterized by the frequent use of substitution, approximation, circumlocution, literal translation, exemplification, word-coinage, repetition, and the infrequent use of cultural-knowledge and paralinguistic CSs. The rare use of paralinguistic strategies is found to be typical of Chinese English learners. The high frequency of literal translation, one first language (L1)-based strategy in our study sample, suggests that FL learners' use of L1-based CSs may depend more upon the developmental stage of their target language than the typology distance between L1 and the target language. The frequency of repetition reveals one fact that the Chinese English learners lack variety and flexibility in their use of CSs. Based on these findings, it was indicated that learners' use of CSs is influenced by a variety of factors, among which the development stage of their interlanguage and their cultural background are identified as two important factors. Some implications are finally suggested for the English foreign language teaching practice in China. PMID:25134668

    2014-01-22

    The anodic oxidation of mercury in the presence of hydrogen peroxide in differential pulse voltammetry (DPV) was used to determine the antioxidant (AO) character of radical scavengers. Hydroperoxide radical is formed at the potentials of the oxidation peak on mercury electrodes, such radical reacting with the antioxidants in different extension. The parameter C10 (antioxidant concentration at which the peak area decreases by 10%) is used to measure the scavenging activity of the individual antioxidants. To establish the scavenging activity of antioxidant mixtures as a whole, the parameter, μ10 as the reverse of V10, V10 being the volume necessary to decrease the peak area in DPV by 10%, was selected. Higher μ10 values correspond to higher scavenging activity. The studies have been extended to aqueous extracts of some species. The results may be useful in explaining the effect of spices in vitro and in vivo studies. PMID:25264569

    PubMed Central

    2015-01-01

    Objective. To implement a learner-led, discussion-based course aimed at exposing second-year pharmacy learners to the study of emerging infectious diseases from a global health perspective and to assess the role and importance of pharmacists in the management of disease outbreaks. Design. Learners examined literature pertinent to an emerging infectious disease in a 3-credit, discussion-based course and participated in peer discussion led by a designated learner. Instructional materials included journal articles, audio-visual presentations, documentaries, book chapters, movies, newspaper/magazine articles, and other materials. Learning outcomes were measured based on the ability of learners to perform critical thinking and analysis, communicate with their peers, and participate in class discussions. Assessment. The course was offered to 2 consecutive cohorts consisting of 14 and 16 learners, respectively. Overall, every learner in the first cohort achieved a final grade of A for the course. In the second cohort, the overall grade distribution consisted of grades of A, B, and C for the course. Learner evaluations indicated that the active-learning, discussion-based environment significantly enhanced interest in the topic and overall performance in the course. Conclusion. The elective course on emerging infectious diseases provided in-depth exposure to disease topics normally not encountered in the pharmacy curriculum. Learners found the material and format valuable, and the course enhanced their appreciation of infectious diseases, research methodology, critical thinking and analysis, and their roles as pharmacists.

  5. Determinants of the activity of beta-lactamase inhibitor combinations.

    PubMed

    Livermore, D M

    1993-01-01

    Inhibitor combinations provide one strategy to overcome beta-lactamase-mediated resistance. Their success depends, obviously, on the inhibitor being able to bind and inactivate the beta-lactamase molecules. Clavulanate, sulbactam and tazobactam are irreversible inactivators of many beta-lactamases, forming covalent complexes which resist hydrolysis. 'Suicide' kinetics are seen with some, but not all, enzymes. All three compounds inactivate staphylococcal penicillinase, the chromosomal beta-lactamases of Proteus vulgaris and Bacteroides spp., and the Class IV beta-lactamases present in some klebsiellae. Tazobactam, but not the other compounds, has moderate activity against some Class I (AmpC) chromosomal beta-lactamases, notably that of Morganella morganii, but not that of Enterobacter cloacae. Both clavulanate and tazobactam are strong inhibitors of the widely distributed TEM and SHV plasmid-mediated beta-lactamases; sulbactam is a weaker inhibitor. Other factors, aside from the affinity of the inhibitor for the enzyme, co-determine the success or failure of inhibition. Potentiation is most readily achieved if little enzyme is produced, and if the organism is very permeable to the inhibitor. Thus, resistance to inhibitor combinations is rare in strains of Haemophilus influenzae and Neisseria gonorrhoeae that produce TEM-beta-lactamase, but is commoner in enterobacteria that produce this enzyme, since these are less permeable and sometimes manufacture very large amounts of enzyme. The partner beta-lactam agent is also important. Irrespective of the inhibitor used, piperacillin is easier to protect against TEM beta-lactamases and the M. morganii Class I enzyme than are ampicillin, amoxycillin or ticarcillin. This may relate to the lower affinity of piperacillin for these enzymes, or to its greater affinity for the bacterial penicillin-binding proteins. Finally, pH can affect the degree of inhibition achieved with sulphones for some beta-lactamases, notably TEM-1

    Background: Lichens produce a variety of substances that possesses pharmacological actions. However, rare products are submitted to rigorous scientific tests or have the risk potential or side effects evaluated. The lack of medical and sanitary control, absence of accurate botanical identification or purity certification, founded in diverse natural products, may represent great danger to population health. This work aimed to evaluate toxic effects and anti-inflammatory action in vivo of Teloschistes flavicans (Sw.) Norm. (TFN) unrefined extracts, as well as determinate its main constituents. Methods: The carrageenan induced paw edema and cotton pellet implant induced granuloma methods were utilized, besides a classic acute toxicity test. TFN acetone extract inhibited carrageenan paw edema on 60, 120, and 180 min (inhibition percentiles of 45.03%, 60.59% and 41.72%). Results: TFN ethereal (inhibition percentiles of 23.95% and 29.01%) and chloroform (inhibition percentiles of 28.8% and 22.04%) extracts inhibited edema on 120 and 180 min. None of the extract inhibited the granuloma development. None of the extract caused death or other acute toxicity signs. Vicanicine (60.26% in ethereal extract and 51.17% in acetone extract), parietine (9.60% in ethereal extract and 15.38% on second), falacinol (0.78% in ether and 14.95% in acetone) and very low concentration of falacinal (0.15% in ethereal extract and 3.32% in acetone extract) were detected in the medicine. Conclusions: The tested extracts have antiedematogenic activity, but are not effective on subchronic inflammation. The extracts do not present toxic effects in administered doses. PMID:21808568

    The study was aimed at evaluating the antioxidant activity of aqueous extract of C. islandica. The antioxidant activity, reducing power, superoxide anion radical scavenging and free radical scavenging activities were studied. The antioxidant activity increased with the increasing amount of extracts (from 50 to 500 microg) added to linoleic acid emulsion. About 50, 100, 250, and 500 microg of aqueous extract of C. islandica showed higher antioxidant activity than 500 microg of alpha-tocopherol. The samples showed 96, 99, 100, and 100% inhibition on peroxidation of linoleic acid, respectively. On the other hand, the 500 microg of alpha-tocopherol showed 77% inhibition on peroxidation on linoleic acid emulsion. Like antioxidant activity, the reducing power, superoxide anion radical scavenging and free radical scavenging activities of C. islandica depends on concentration and increasing with increased amount of sample. The results obtained in the present study indicate that C. islandica is a potential source of natural antioxidant. PMID:11849836

    Introduction Individuals with intellectual disabilities are rarely targeted by the current human immunodeficiency virus (HIV) response, thereby reducing their access to HIV information and services. Currently, little is known about the HIV knowledge and sexual practices of young Nigerians with intellectual disabilities. Thus, this study sought to compare the HIV knowledge and sexual practices of learners with mild/moderate intellectual disabilities and non-disabled learners (NDL) in Nigeria. Findings could help in the development of HIV interventions that are accessible to Nigerian learners with intellectual impairments. Methods This cross-sectional, comparative study utilized a survey to investigate HIV knowledge and sexual practices among learners with mild/moderate intellectual disabilities and NDL in Nigeria. Learners with mild/moderate intellectual disabilities (n=300) and NDL (n=300) within the age range of 12 to 19 years drawn from schools across Oyo State, Nigeria, completed a structured questionnaire to assess their knowledge of HIV transmission and sexual practices. Results Significantly more learners with mild/moderate intellectual disabilities (62.2%) than NDL 48 (37.8%) reported having sexual experience (p=0.002). Of the sexually experienced female learners with mild/moderate intellectual disabilities, 28 (68.3%) reported history of rape compared with 9 (2.9%) of female NDL (p=0.053). Intellectual impairment was significantly associated with lower HIV transmission knowledge scores (p<0.001). Learners with mild/moderate intellectual disabilities were less likely than NDL (p<0.001) to have heard about HIV from most of the common sources of HIV information. In addition, when compared with non-disabled learners, learners with mild/moderate intellectual disabilities were significantly more likely to have reported inconsistent condom use with boyfriends/girlfriends (p<0.001), with casual sexual partners (p<0.001) and non-use of condom during last sexual

    Herbal medicinal products are commonly used in alternative treatment of menopausal hot flushes. In a recent clinical study, Salvia officinalis tincture was found to reduce hot flush frequency and intensity. The aim of the current study was the investigation of the mechanism(s) responsible for the anti-hot flush activity of S. officinalis and determination of its active principle(s). The 66% ethanolic tincture, as well as the n-hexane, CHCl₃, and aqueous ethanolic subextracts obtained from the tincture were studied in vitro for two of the most relevant activities, estrogenicity and selective serotonin reuptake inhibition. Because of an increased risk of menopausal women to suffer from Alzheimer's disease, an in vitro acetylcholinesterase inhibition assay was also employed. No activity was observed in the selective serotonin reuptake inhibition or the acetylcholinesterase inhibition assays at the highest test concentrations. The tincture showed no estrogenic effects whereas the aqueous ethanolic subextract exhibited estrogenicity in the ERLUX assay with an EC₅₀ value of 64 µg/mL. Estrogenic activity-guided fractionation of the aqueous ethanolic subextract by a combination of reverse-phase vacuum liquid chromatography and gel chromatography identified luteolin-7-O-glucuronide (EC₅₀ 129 µg/mL) as the active component of the vacuum liquid chromatography fraction 4 (EC₅₀ 69 µg/mL). Luteolin-7-O-glucoside was identified as the putative estrogenic principle of the most potent minor fraction (7.6.7.6, EC₅₀ 0.7 µg/mL) obtained from the initial vacuum liquid chromatography fraction 7 (EC₅₀ 3 µg/mL). This study suggests the involvement of common and ubiquitous estrogenic flavonoids in the anti-hot flush effect of Salvia officinalis, a safe and commonly used herbal medicinal product during the menopause.

  11. Effective instruction for English learners.

    Calderón, Margarita; Slavin, Robert; Sánchez, Marta

    2011-01-01

    The fastest-growing student population in U.S. schools today is children of immigrants, half of whom do not speak English fluently and are thus labeled English learners. Although the federal government requires school districts to provide services to English learners, it offers states no policies to follow in identifying, assessing, placing, or instructing them. Margarita Calderón, Robert Slavin, and Marta Sánchez identify the elements of effective instruction and review a variety of successful program models. During 2007-08, more than 5.3 million English learners made up 10.6 percent of the nation's K-12 public school enrollment. Wide and persistent achievement disparities between these English learners and English-proficient students show clearly, say the authors, that schools must address the language, literacy, and academic needs of English learners more effectively. Researchers have fiercely debated the merits of bilingual and English-only reading instruction. In elementary schools, English learners commonly receive thirty minutes of English as a Second Language (ESL) instruction but attend general education classes for the rest of the day, usually with teachers who are unprepared to teach them. Though English learners have strikingly diverse levels of skills, in high school they are typically lumped together, with one teacher to address their widely varying needs. These in-school factors contribute to the achievement disparities. Based on the studies presented here, Calderón, Slavin, and Sánchez assert that the quality of instruction is what matters most in educating English learners. They highlight comprehensive reform models, as well as individual components of these models: school structures and leadership; language and literacy instruction; integration of language, literacy, and content instruction in secondary schools; cooperative learning; professional development; parent and family support teams; tutoring; and monitoring implementation and outcomes

    Massive open online courses (MOOCs) provide an opportunity for people to access free courses offered by top universities in the world and therefore attracted great attention and engagement from college teachers and students. However, with contrast to large scale enrollment, the completion rate of these courses is really low. One of the reasons for students to quit learning process is problems which they face that could not be solved by discussing them with classmates. In order to keep them staying in the course, thereby further improving the completion rate, we address the task of study partner recommendation for students based on both content information and social network information. By analyzing the content of messages posted by learners in course discussion forum, we investigated the learners' behavior features to classify the learners into three groups. Then we proposed a topic model to measure learners' course knowledge awareness. Finally, a social network was constructed based on their activities in the course forum, and the relationship in the network was then employed to recommend study partners for target learner combined with their behavior features and course knowledge awareness. The experiment results show that our method achieves better performance than recommending method only based on content information. PMID:25663836

  9. Sensors at Centrosomes Reveal Determinants of Local Separase Activity

    PubMed Central

    Agircan, Fikret Gurkan; Schiebel, Elmar

    2014-01-01

    Separase is best known for its function in sister chromatid separation at the metaphase-anaphase transition. It also has a role in centriole disengagement in late mitosis/G1. To gain insight into the activity of separase at centrosomes, we developed two separase activity sensors: mCherry-Scc1(142-467)-ΔNLS-eGFP-PACT and mCherry-kendrin(2059-2398)-eGFP-PACT. Both localize to the centrosomes and enabled us to monitor local separase activity at the centrosome in real time. Both centrosomal sensors were cleaved by separase before anaphase onset, earlier than the corresponding H2B-mCherry-Scc1(142-467)-eGFP sensor at chromosomes. This indicates that substrate cleavage by separase is not synchronous in the cells. Depletion of the proteins astrin or Aki1, which have been described as inhibitors of centrosomal separase, did not led to a significant activation of separase at centrosomes, emphasizing the importance of direct separase activity measurements at the centrosomes. Inhibition of polo-like kinase Plk1, on the other hand, decreased the separase activity towards the Scc1 but not the kendrin reporter. Together these findings indicate that Plk1 regulates separase activity at the level of substrate affinity at centrosomes and may explain in part the role of Plk1 in centriole disengagement.

    Estrogen receptors ERα and ERβ share considerable sequence homology yet exert opposite effects on breast cancer cell proliferation. While the proliferative role of ERα in breast tumors is well characterized, it is not clear whether the antitumor activity of ERβ can be mobilized in breast cancer cells. Here, we have shown that phosphorylation of a tyrosine residue (Y36) present in ERβ, but not in ERα, dictates ERβ-specific activation of transcription and is required for ERβ-dependent inhibition of cancer cell growth in culture and in murine xenografts. Additionally, the c-ABL tyrosine kinase and EYA2 phosphatase directly and diametrically controlled the phosphorylation status of Y36 and subsequent ERβ function. A nonphosphorylatable, transcriptionally active ERβ mutant retained antitumor activity but circumvented control by upstream regulators. Phosphorylation of Y36 was required for ERβ-mediated coactivator recruitment to ERβ target promoters. In human breast cancer samples, elevated phosphorylation of Y36 in ERβ correlated with high levels of c-ABL but low EYA2 levels. Furthermore, compared with total ERβ, the presence of phosphorylated Y36–specific ERβ was strongly associated with both disease-free and overall survival in patients with stage II and III disease. Together, these data identify a signaling circuitry that regulates ERβ-specific antitumor activity and has potential as both a prognostic tool and a molecular target for cancer therapy.

  11. Ligand determinants of nisin for its induction activity.

    PubMed

    Ge, Xiaoxuan; Teng, Kunling; Wang, Jian; Zhao, Fangyuan; Wang, Fangfang; Zhang, Jie; Zhong, Jin

    2016-07-01

    Nisin has been widely used in the food industry as a safe and natural preservative and has the potential to be used as a biomedicine. Improving nisin production is important for its enormous applications. Nisin A is produced in Lactococcus lactis and its biosynthesis is induced through the regulation of the 2-component system NisKR. In this study, alanine-scanning mutagenesis was applied to study the key structure or AA in nisin for inducing the 2-component system NisKR to regulate downstream gene expression. Assay of β-galactosidase activity revealed that either ring A or ring B was necessary for nisin to induce lacZ reporter gene expression. A substituted first ring formed by Thr2 and Cys7 in S3A instead of ring A (formed by Ser3 and Cys7) fully retained nisin induction activity. Mutation of cationic AA and addition of cationic ions hardly affected nisin induction activity. These results demonstrated that the N-terminal ring structures in nisin were involved in activating NisKR to act as an inducing molecule, whereas the electrostatic force might not contribute to this process. In addition, 2 specific residues were revealed to have potential for improving both nisin induction and antimicrobial activity, which might be used for increasing nisin production. PMID:27132090

  15. Microbial metabolic activity in soil as measured by dehydrogenase determinations

    NASA Technical Reports Server (NTRS)

    Casida, L. E., Jr.

    1977-01-01

    The dehydrogenase technique for measuring the metabolic activity of microorganisms in soil was modified to use a 6-h, 37 C incubation with either glucose or yeast extract as the electron-donating substrate. The rate of formazan production remained constant during this time interval, and cellular multiplication apparently did not occur. The technique was used to follow changes in the overall metabolic activities of microorganisms in soil undergoing incubation with a limiting concentration of added nutrient. The sequence of events was similar to that obtained by using the Warburg respirometer to measure O2 consumption. However, the major peaks of activity occurred earlier with the respirometer. This possibly is due to the lack of atmospheric CO2 during the O2 consumption measurements.

  16. Determination of host RNA helicases activity in viral replication

    PubMed Central

    Sharma, Amit; Boris-Lawrie, Kathleen

    2016-01-01

    RNA helicases are encoded by all eukaryotic and prokaryotic cells and a minority of viruses. Activity of RNA helicases is necessary for all steps in the expression of cells and viruses and the host innate response to virus infection. Their vast functional repertoire is attributable to the core ATPase-dependent helicase domain in conjunction with flanking domains that are interchangeable and engage viral and cellular cofactors. Here, we address the important issue of host RNA helicases that are necessary for replication of a virus. The chapter covers approaches to identification and characterization of candidate helicases and methods to define the biochemical and biophysical parameters of specificity and functional activity of the enzymes. We discuss the context of cellular RNA helicase activity and virion-associated RNA helicases. The methodology and choice of controls fosters the assessment of the virologic scope of RNA helicases across divergent cell lineages and viral replication cycles. PMID:22713331

    The proposed method for measuring hyaluronidase activity of microorganism is based on prevention of hyaluronic acid clot formation with rivanol under the effect of hyaluronidase. This made possible the quantitative and qualitative detection of hyaluronidase activities of different staphylococcus species and strains. The maximum level of the enzyme and highest rate of its detection were typical of St. aureus. Its strains producing hyaluronidase in quantities of at least 0.5 IU are significantly (p < 0.01) more often isolated from medical staff. PMID:9575732

  1. On the determination of oxygen abundances in chromospherically active stars

    NASA Astrophysics Data System (ADS)

    Morel, T.; Micela, G.

    2004-08-01

    We discuss oxygen abundances derived from [O I] λ6300s and the O I triplet in stars spanning a wide range in chromospheric activity level, and show that these two indicators yield increasingly discrepant results with higher chromospheric/coronal activity measures. While the forbidden and permitted lines give fairly consistent results for solar-type disk dwarfs, spuriously high O I triplet abundances are observed in young Hyades and Pleiades stars, as well as in individual components of RS CVn binaries (up to 1.8 dex). The distinct behaviour of the [O I]-based abundances which consistently remain near-solar suggests that this phenomenon mostly results from large departures from LTE affecting the O I triplet at high activity level that are currently unaccounted for, but also possibly from a failure to adequately model the atmospheres of K-type stars. These results suggest that some caution should be exercised when interpreting oxygen abundances in active binaries or young open cluster stars.

    2016-09-01

    Pancreatin is a biotechnological product containing an enzyme complex, obtained from porcine pancreas, that is employed in treating pancreatic diseases. Experiments regarding the stability of the pharmaceutical formulation containing pancreatin were performed using standard binary mixtures with 6 excipients in a 1:1 ratio (m/m) and a commercial formulation. To accomplish these goals, samples were stored for 1, 3 and 6 months at 40 ± 1 °C and 75 ± 5 % relative humidity (RH) and 40 ± 1 °C and 0 % RH. Stress testing was also performed. All samples were analyzed to evaluate the α-amylase, lipase and protease activities through UV/Vis spectrophotometry. The results revealed that the excipient proprieties and the storage conditions affected enzyme stability. Humidity was a strong influencing factor in the reduction of α-amylase and protease activities. Stress testing indicated that pH 9.0 and UV light did not induce substantial alterations in enzyme activity. PMID:27383890

    2016-07-22

    Antibacterial-guided fractionation of the Dictyoceratid sponges Lamellodysidea sp. and two samples of Dysidea granulosa yielded 14 polybrominated, diphenyl ethers including one new methoxy-containing compound (8). Their structures were elucidated by interpretation of spectroscopic data of the natural product and their methoxy derivatives. Most of the compounds showed strong antimicrobial activity with low- to sub-microgram mL(-1) minimum inhibitory concentrations against drug-susceptible and drug-resistant strains of Staphylococcus aureus and Enterococcus faecium, and two compounds inhibited Escherichia coli in a structure-dependent manner.

    Schenerman, M A; Collins, T J

    1994-03-01

    A method for measuring the binding of chimeric IgG BR-96 to the Lewis Y antigen using the ImmunoDetection technology has been developed. The procedure is rapid (2 min), highly reproducible (< 5% CV), and has excellent correlation with the Lewis Y and anti-idiotypic enzyme immunoassays. Samples that were degraded by heat or by repeated freeze-thaw cycles showed reduced binding activity. There was minimal cross-reactivity with other proteins typically found in hybridoma media or with another chimeric IgG directed against a different antigen (L6). The fact that this assay can be performed using conventional HPLC equipment makes it especially attractive because it can be completely automated using equipment readily available. PMID:8203752

  1. Determinants of physical activity and exercise in healthy older adults: A systematic review

    PubMed Central

    2011-01-01

    Background The health benefits of regular physical activity and exercise have been widely acknowledged. Unfortunately, a decline in physical activity is observed in older adults. Knowledge of the determinants of physical activity (unstructured activity incorporated in daily life) and exercise (structured, planned and repetitive activities) is needed to effectively promote an active lifestyle. Our aim was to systematically review determinants of physical activity and exercise participation among healthy older adults, considering the methodological quality of the included studies. Methods Literature searches were conducted in PubMed/Medline and PsycINFO/OVID for peer reviewed manuscripts published in English from 1990 onwards. We included manuscripts that met the following criteria: 1) population: community dwelling healthy older adults, aged 55 and over; 2) reporting determinants of physical activity or exercise. The outcome measure was qualified as physical activity, exercise, or combination of the two, measured objectively or using self-report. The methodological quality of the selected studies was examined and a best evidence synthesis was applied to assess the association of the determinants with physical activity or exercise. Results Thirty-four manuscripts reporting on 30 studies met the inclusion criteria, of which two were of high methodological quality. Physical activity was reported in four manuscripts, exercise was reported in sixteen and a combination of the two was reported in fourteen manuscripts. Three manuscripts used objective measures, twenty-two manuscripts used self-report measures and nine manuscripts combined a self-report measure with an objective measure. Due to lack of high quality studies and often only one manuscript reporting on a particular determinant, we concluded "insufficient evidence" for most associations between determinants and physical activity or exercise. Conclusions Because physical activity was reported in four manuscripts

    2002-07-01

    Thirty-two surface (0-20 cm) soil samples were collected from different locations in Egypt representing non-polluted, moderately and highly polluted soils. The aim of this study was to evaluate total Zn content in alluvial soils of Nile Delta in Egypt by using the delayed neutron activation analysis technique (DNAA), in the irradiation facilities of the first Egyptian research reactor (ET-RR-1). The gamma-ray spectra were recorded with a hyper pure germanium detection system. The well resolved gamma-ray peak at 1116.0 keV was efficiently used for 65Zn content determination. Zn content in non-polluted soil samples ranged between 74.1 and 103.8 ppm with an average of 98.5 +/- 5.1 ppm. Zn content in moderately polluted soils ranged between 136.0 and 232.5 ppm with an average of 180.1 +/- 32.6 ppm. The highest Zn levels ranging from 240.0 and 733.0 ppm with an average of 410.3 +/- 54.4 ppm, were observed in soil samples collected from, either highly polluted agricultural soils exposed to prolonged irrigation with industrial wastewater or surface soil samples from industrial sites.

  7. Active heterotrophic biomass and sludge retention time (SRT) as determining factors for biodegradation kinetics of pharmaceuticals in activated sludge.

    PubMed

    Majewsky, Marius; Gallé, Tom; Yargeau, Viviane; Fischer, Klaus

    2011-08-01

    The present study investigates the biodegradation of pharmaceutically active compounds (PhACs) by active biomass in activated sludge. Active heterotrophs (X(bh)) which are known to govern COD removal are suggested as a determining factor for biological PhAC removal as well. Biodegradation kinetics of five polar PhACs were determined in activated sludge of two wastewater treatment plants which differed in size, layout and sludge retention time (SRT). Results showed that active fractions of the total suspended solids (TSS) differed significantly between the two sludges, indicating that TSS does not reveal information about heterotrophic activity. Furthermore, PhAC removal was significantly faster in the presence of high numbers of heterotrophs and a low SRT. Pseudo first-order kinetics were modified to include X(bh) and used to describe decreasing PhAC elimination with increasing SRT. PMID:21652206

  14. Are Deaf Students Visual Learners?

    PubMed

    Marschark, Marc; Morrison, Carolyn; Lukomski, Jennifer; Borgna, Georgianna; Convertino, Carol

    2013-06-01

    It is frequently assumed that by virtue of their hearing losses, deaf students are visual learners. Deaf individuals have some visual-spatial advantages relative to hearing individuals, but most have been are linked to use of sign language rather than auditory deprivation. How such cognitive differences might affect academic performance has been investigated only rarely. This study examined relations among deaf college students' language and visual-spatial abilities, mathematics problem solving, and hearing thresholds. Results extended some previous findings and clarified others. Contrary to what might be expected, hearing students exhibited visual-spatial skills equal to or better than deaf students. Scores on a Spatial Relations task were associated with better mathematics problem solving. Relations among the several variables, however, suggested that deaf students are no more likely to be visual learners than hearing students and that their visual-spatial skill may be related more to their hearing than to sign language skills.

  16. Symphony: A case study for exploring and describing design methods and guidelines for learner-centered design

    NASA Astrophysics Data System (ADS)

    Quintana, Christopher

    Learner-centered design is an evolving software design perspective addressing the needs of learners---a specific audience trying to work in and understand new work practices in which they have a novice or naive understanding. Learner-centered design involves designing software that incorporates work support features (or scaffolding features) informed by social constructivist learning theories. By adopting a constructivist "learning by doing" perspective, scaffolds should support learners so they can mindfully engage in previously inaccessible work activity, which in turn allows those learners to progressively gain a better understanding of the new work. While there is an intuitive notion of "learner-centered design", there is less specific design information for developing learner-centered software. As a result, learner-centered software results from "educated guesses" and ad-hoc design approaches rather than from systematic design methods. Thus there is a need for specific design guidance to facilitate the development of learner-centered tools that help learners see the tasks, terminology, tools, etc. in the new work context and engage in that work. The research in this dissertation provides a more specific base of learner-centered design descriptions, methods, and guidelines to analyze work practices and design and evaluate scaffolds. The research approach involves using the development of Symphony---a scaffolded integrated tool environment for high-school students learning the work of computational science inquiry---as a case study to develop the learner-centered design approach. Symphony incorporates a variety of science tools with process scaffolding to support students in performing complex air pollution investigations. Six ninth-grade students used Symphony to investigate air quality questions for several weeks in an environmental science class. The student testing helped assess the effectiveness of the software scaffolding and in turn, the learner

  17. Modeling the effects of multicontextual physics instruction on learner expectations and understanding of force and motion systems

    NASA Astrophysics Data System (ADS)

    Deese Becht, Sara-Maria Francis

    1999-11-01

    The purpose of this study is two-fold involving both practical and theoretical modeling components. The practical component, an experiential-learning phase, investigated a study population for effects that increasing levels of multicontextual physics activities have on student understanding of Newtonian systems of motion. This contextual-learning model measured learner convictions and non-response gaps and analyzed learner response trends on context, technology, challenge, growth, and success. The theoretical component, a model-building phase, designed a dynamic-knowing model for learning along a range of experiential tasks, from low to high context, monitored for indicators of learning in science and mathematics: learner academic performance and ability, learner control and academic attitude, and a learner non- response gap. This knowing model characterized a learner's process-of-knowing on a less to more expert- like learner-response continuum using performance and perspective indices associated with level of contextual- imagery referent system. Data for the contextual-learning model were collected on 180 secondary subjects: 72 middle and 108 high, with 36 physics subjects as local experts. Subjects were randomly assigned to one of three experimental groups differing only on context level of force and motion activities. Three levels of information were presented through context-based tasks: momentum constancy as inertia, momentum change as impulse, and momentum rate of change as force. The statistical analysis used a multi-level factorial design with repeated measures and discriminate analysis of response-conviction items. Subject grouping criteria included school level, ability level in science and mathematics, gender and race. Assessment criteria used pre/post performance scores, confidence level in physics concepts held, and attitude towards science, mathematics, and technology. Learner indices were computed from logit- transforms applied to learner outcomes

    Augmented Reality (AR) is a technology that is projected to have more significant role in teaching and learning, particularly in visualising abstract concepts in the learning process. AR is a technology is based on visually oriented technique. Thus, it is suitable for deaf learners since they are generally classified as visual learners. Realising the importance of visual learning style for deaf learners in learning Science, this paper reports on a preliminary study of on an ongoing research on problems faced by deaf learners in learning the topic on Microorganisms. Being visual learners, they have problems with current text books that are more text-based that graphic based. In this preliminary study, a qualitative approach using the ethnographic observational technique was used so that interaction with three deaf learners who are participants throughout this study (they are also involved actively in the design and development of the AR Book). An interview with their teacher and doctor were also conducted to identify their learning and medical problems respectively. Preliminary findings have confirmed the need to design and develop a special Augmented Reality Book called AR-Science for Deaf Learners (AR-SiD).

    Background Efforts are made to enhance in-class learner engagement because it stimulates and enhances learning. However, it is not easy to quantify learner engagement. This study aimed to develop and validate an observation tool for instructor and student behaviors to determine and compare in-class learner engagement levels in four different class types delivered by the same instructor. Methods Observer pairs observed instructor and student behaviors during lectures in large class (LLC, n=2) with third-year medical students, lectures in small class (LSC, n=6) and case-based teaching sessions (CBT, n=4) with fifth-year students, and problem-based learning (PBL) sessions (~7 hours) with second-year students. The observation tool was a revised form of STROBE, an instrument for recording behaviors of an instructor and four randomly selected students as snapshots for 5-min cycles. Instructor and student behaviors were scored 1–5 on this tool named ‘in-class engagement measure (IEM)’. The IEM scores were parallel to the degree of behavior's contribution to active student engagement, so higher scores were associated with more in-class learner engagement. Additionally, the number of questions asked by the instructor and students were recorded. A total of 203 5-min observations were performed (LLC 20, LSC 85, CBT 50, and PBL 48). Results Interobserver agreement on instructor and student behaviors was 93.7% (κ=0.87) and 80.6% (κ=0.71), respectively. Higher median IEM scores were found in student-centered and problem-oriented methods such as CBT and PBL. A moderate correlation was found between instructor and student behaviors (r=0.689). Conclusions This study provides some evidence for validity of the IEM scores as a measure of student engagement in different class types. PMID:25308966

  11. Activation and Micropore Structure Determination of Activated Carbon-Fiber Composites

    SciTech Connect

    Jagtoyen, M.; Derbyshire, F.

    1999-04-23

    Previous work focused on the production of carbon fiber composites and subsequently activating them to induce adsorbent properties. One problem related to this approach is the difficulty of uniformly activating large composites. In order to overcome this problem, composites have been made from pre-activated fibers. The loss of surface area upon forming the composites after activation of the fibers was investigated. The electrical resistivity and strength of these composites were compared to those made by activation after forming. It was found that the surface area is reduced by about 35% by forming the composite from pre-activated fibers. However, the properties of the activated sample are very uniform: the variation in surface area is less than {+-}0.5%. So, although the surface area is somewhat reduced, it is believed that making composites from pre-activated fibers could be useful in applications where the BET surface area is not required to be very high. The strength of the composites produced from pre-activated fibers is lower than for composites activated after forming when the carbon burnoff is below 45%. For higher burnoffs, the strength of composites made with pre-activated fibers is as good or better. In both cases, there is a dramatic decrease in strength when the fiber:binder ratio is reduced below 4:1. The electrical resistivity is slightly higher for composites made from pre-activated fibers than for composites that are activated after forming, other parameters being constant (P-200 fibers, similar carbon burnoffs). For both types of composite the resistivity was also found to increase with carbon burnoff. This is attributed to breakage of the fiber causing shorter conductive paths. The electrical resistivity also increases when the binder content is lowered, which suggests that there are fewer solid contact points between the fibers.

    Buxner, Sanlyn; Impey, Chris David; Wenger, Matthew; Formanek, Martin; Romine, James M.

    2016-01-01

    Massively open online courses (MOOCs) are becoming increasingly popular ways to reach diverse lifelong learners all over the world. Although MOOCs resemble more formal classes (e.g. videos of content, quizzes, activities), they are often used by informal audiences from home. Recently, MOOCs have become more utilized by universities to conduct outreach as they explore how to use MOOCs to reach new potential learners. Despite the rapid adaption of MOOCs, little is known about individuals who choose to take a MOOC, how they interact with the course materials, and what motivates them to finish the course.We present results of a study of lifelong learners engaged in an astronomy "101" MOOC. Through analysis of registered learners' behaviors as well as self-reported responses to a survey about science, we were able to characterize a subset of the learners engaged in the MOOC during its first offering. Overall, 25363 learners from over 100 countries registered for the MOOC. Of those, 14900 accessed at least one part of the course. Learners were recruited to complete a survey of their knowledge and attitudes towards science. Of the learner group who opened the course, 2889 individuals completed the survey, 2465 of those were able to be linked to their usage of the MOOC through a unique identifier.Learners represented a wide-range of ages, professions, and previous science experience. The best predictors for MOOC completion were engagement in the first activity and first writing assignment and engagement in the online forum. Learners were very interested in science prior to their registration, had higher basic science knowledge that most undergraduate students enrolled in a parallel astronomy course, and used online searches and science sites to get their information about science. As we reach out to a worldwide audience to learners in these massively open online courses, understanding their motivations and behaviors will be essential. This work is helping us understand and

    1997-09-05

    Rigid, high surface area activated carbon fiber composites have been produced with high permeabilities for environmental applications in gas and water purification. These novel monolithic adsorbents can be produced in single pieces to a given size and shape. The project involves a collaboration between the Oak Ridge National Laboratory (ORNL) and the Center for Applied Energy Research (CAER), University of Kentucky. The carbon fiber composites are produced at the ORNL and activated at the CAER using different methods, with the aims of producing a uniform degree of activation, and of closely controlling pore structure and adsorptive properties. The main focus of the present work has been to find a satisfactory means to uniformly activate large samples of carbon fiber composites and produce controlled pore structures. Several environmental applications have been explored for the activated carbon fiber composites. One of these was to evaluate the activated composites for the separation of CH{sub 4}-CO{sub 2} mixtures, and an apparatus was constructed specifically for this purpose. The composites were further evaluated in the cyclic recovery of volatile organics. The activated carbon fiber composites have also been tested for possible water treatment applications by studying the adsorption of sodium pentachlorophenolate, PCP.

    2009-05-01

    Few studies analyze determinants and patterns of physical activity among college students, so it has not been possible to carry out effective interventions to promote this practice. The aim of this study was to analyze the associations between some personal, social, and environmental determinants, practice of physical activity and future intention to practice in a sample of 639 university students (321 men and 318 women), mean age 21.43 years (+/- 2.78). Physical fitness self-perception, physical activity history, and coach's support to practice physical activity have a direct effect on the practice of physical activity and an indirect effect on future intention to practice, both in men and women. The practice of physical activity has also a direct effect on future intention to practice. Likewise, the participation in sport competitions predicts practice of physical activity and future intention in men, whereas being a member of a sports club predicts practice and future intention in women.

  20. Getting it right by getting it wrong: When learners change languages

    PubMed Central

    Hudson Kam, Carla L.; Newport, Elissa L.

    2009-01-01

    When natural language input contains grammatical forms that are used probabilistically and inconsistently, learners will sometimes reproduce the inconsistencies; but sometimes they will instead regularize the use of these forms, introducing consistency in the language that was not present in the input. In this paper we ask what produces such regularization. We conducted three artificial language experiments, varying the use of determiners in the types of inconsistency with which they are used, and also comparing adult and child learners. In Experiment 1 we presented adult learners with scattered inconsistency – the use of multiple determiners varying in frequency in the same context – and found that adults will reproduce these inconsistencies at low levels of scatter, but at very high levels of scatter will regularize the determiner system, producing the most frequent determiner form almost all the time. In Experiment 2 we showed that this is not merely the result of frequency: when determiners are used with low frequencies but in consistent contexts, adults will learn all of the determiners veridically. In Experiment 3 we compared adult and child learners, finding that children will almost always regularize inconsistent forms, whereas adult learners will only regularize the most complex inconsistencies. Taken together, these results suggest that regularization processes in natural language learning, such as those seen in the acquisition of language from non-native speakers or in the formation of young languages, may depend crucially on the nature of language learning by young children.

    Sprague, C. J.; Grill, M. R.; Genet, C. L.; Genet, R. M.

    2002-05-01

    In the fall of 2001, learner centered education principles were applied to an introductory astronomy course at the Superstition Mountain Campus of Central Arizona College (CAC). The course was cooperatively designed and managed by the students themselves (especially Sprague and Grill), an assistant course facilitator (C. Genet), and the course instructor and developer (R. Genet). Although some time was devoted to lectures accompanied by photographic slides and open to the public, the bulk of the time was devoted to student projects. Students built telescopes, including solar, zenith, and Galileo, took measurements, made calculations, mapped stars, and determined the circumference of the earth via zenith observations at Apache Junction and at Mt. Hopkins, 120 miles away. A three-day field trip to Lowell Observatory included a tour, observations through the famous 24-inch Clark refractor, and a conference on `Undergraduate Astronomical Research' which included talks on stellar photometry by G. W. Lockwood and R. M. Genet. A second three-day field trip included a tour and observations at Kitt Peak National Observatory (0.4 m telescope), a tour of the observatories on Mt. Hopkins, and a conference on `Learner-Centered Astronomy Education.' The community college students were joined by doctoral students and alumni from the Union Institute and University, as well as by Campua Dean James Stuckey from CAC and his wife Beverly Santos of Northern Arizona University. By allowing students the freedom to explore and expand their knowledge at a rate appropriate to each individual, the students attained levels of confidence not found in traditional teaching styles. We are pleased to acknowledge Dean Stuckey who made this class possible. We also wish to thank Wesley Lockwood and Robert Bargoon at Lowell Observatory, Robert Wilson at Kitt Peak National Observatory, and Daniel Brocious at the Smithsonian's Whipple Observatory for their invaluable assistance during our field trips.

  20. The effect of different inter-pad distances on the determination of active drag using the Measuring Active Drag system.

    PubMed

    Schreven, S; Toussaint, H M; Smeets, J B J; Beek, P J

    2013-07-26

    The Measuring Active Drag (MAD) system was developed to determine active drag in swimming by measuring the push-off force exerted at fixed pads placed below the waterline. The imposed inter-pad distance, which to date has been kept constant while using the MAD system, could affect the active drag because it requires the use of different stroke frequencies. The aim of the present study was therefore to determine the effect of inter-pad distance on active drag at a given speed. In particular, drag-velocity curves at three different inter-pad distances (1.25m, 1.35m and 1.45m) were determined using the MAD system for eleven competitive swimmers. Variation of 16% in inter-pad distance (14% change in stroke frequency) revealed no significant difference in calculated active drag between different inter-pad distances and a low (<5%) average coefficient of variation over different inter-pad distances was found. In addition, inter-test reliability, which was determined for the two 1.35m conditions only, was high (ICC>0.90) for measurements on two consecutive days. The results suggest that it may not be necessary to adapt the inter-pad distance of the MAD system based on anthropometric characteristics of the subject or the velocity-related stroke length in free swimming.

    The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development “best practices” and effective models for change difficult. We aimed to determine the extent to which postdoctoral fellows (i.e., future biology faculty) believed in and implemented evidence-based pedagogies after completion of a 2-yr professional development program, Faculty Institutes for Reforming Science Teaching (FIRST IV). Postdocs (PDs) attended a 2-yr training program during which they completed self-report assessments of their beliefs about teaching and gains in pedagogical knowledge and experience, and they provided copies of class assessments and video recordings of their teaching. The PDs reported greater use of learner-centered compared with teacher-centered strategies. These data were consistent with the results of expert reviews of teaching videos. The majority of PDs (86%) received video ratings that documented active engagement of students and implementation of learner-centered classrooms. Despite practice of higher-level cognition in class sessions, the items used by the PDs on their assessments of learning focused on lower-level cognitive skills. We attributed the high success of the FIRST IV program to our focus on inexperienced teachers, an iterative process of teaching practice and reflection, and development of and teaching a full course.

  19. Physical activity and physical activity induced energy expenditure in humans: measurement, determinants, and effects.

    PubMed

    Westerterp, Klaas R

    2013-01-01

    Physical activity is defined as any bodily movement produced by skeletal muscles that results in energy expenditure. The doubly labeled water method for the measurement of total energy expenditure (TEE), in combination with resting energy expenditure, is the reference for physical activity under free-living conditions. To compare the physical activity level (PAL) within and between species, TEE is divided by resting energy expenditure resulting in a figure without dimension. The PAL for sustainable lifestyles ranges between a minimum of 1.1-1.2 and a maximum of 2.0-2.5. The average PAL increases from 1.4 at age 1 year to 1.7-1.8 at reproductive age and declines again to 1.4 at age 90 year. Exercise training increases PAL in young adults when energy balance is maintained by increasing energy intake. Professional endurance athletes can reach PAL values around 4.0. Most of the variation in PAL between subjects can be ascribed to predisposition. A higher weight implicates higher movement costs and less body movement but not necessarily a lower PAL. Changes in physical activity primarily affect body composition and to a lesser extent body weight. Modern man has a similar PAL as a wild mammal of a similar body size. PMID:23637685

    Experimental study of nonstandard neutrino properties using high-intensity artificial neutrino sources requires the activity of the sources to be determined with high accuracy. In the BEST project, a calorimetric system for measurement of the activity of high-intensity (a few MCi) neutrino sources based on {sup 51}Cr with an accuracy of 0.5–1% is created. In the paper, the main factors affecting the accuracy of determining the neutrino source activity are discussed. The calorimetric system design and the calibration results using a thermal simulator of the source are presented.
