    2012-07-01

    The extent to which nuclear energy technologies are, in some sense, "stigmatised" by historical environmental and military associations is of particular interest in contemporary debates about sustainable energy policy. Recent claims in the literature suggest that despite such stigmatisation, lay views on such technologies may be shifting towards a "reluctant acceptance," in the light of concerns about issues like anthropogenic climate change. In this paper, we report on research into learning and reasoning processes concerned with a largely unknown nuclear energy technology; namely fusion power. We focus on the role of the nuclear label, or "brand," in informing how lay citizens make sense of the nature of this technology. Our findings derive from a comparative analysis of data generated in Spain and Britain, using the same methodology.

    2009-01-01

    Full Text Available Problem statement: As an efficient means to increase global competitiveness, technological capabilities and potential for local innovation, organizations in the developing countries are working hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs. Technology recipient characteristics, as one of the important actors/facilitators of inter-firm technology transfer, have increasingly become crucial factors in determining the success or failure of inter-firm technology transfer within IJVs. Since the current issue on inter-firm Technology Transfer (TT in the developing countries is centered on the efficiency and effectiveness of the transfer process by the Multinationals (MNCs therefore the success is often associated with or measured by degree of technology transferred to local partners. Based on the underlying knowledge-based view and organizational learning perspective, this study aims to empirically examine the effects of two critical elements of technology recipient characteristics: Absorptive Capacity (ACAP and Recipient Collaborativeness (RCOL on degree of technology transfer: Degree of tacit and explicit knowledge in IJVs. Approach: Using the quantitative analytical approach, the theoretical model and hypotheses in this study were tested based on empirical data gathered from 128 joint venture companies registered with the Registrar of Companies Of Malaysia (ROC. Data obtained from the survey questionnaires were analyzed using the correlation coefficients and multiple linear regression analyses. Results: The results revealed that recipient collaborativeness as the critical element of technology recipient characteristics has strong significant effects on both degrees of tacit and explicit knowledge. Although absorptive capacity has been strongly emphasized of its significance effect, however, the results are not statistically significant

    2015-11-01

    Full Text Available Maltodextrin (MX is an ingredient in high demand in the food industry, mainly for its useful physical properties which depend on the dextrose equivalent (DE. The DE has however been shown to be an inaccurate parameter for predicting the performance of the MXs in technological applications, hence commercial MXs were characterized by mass spectrometry (MS to determine their molecular weight distribution (MWD and degree of polymerization (DP. Samples were subjected to different water activities (aw. Water adsorption was similar at low aw, but radically increased with the DP at higher aw. The decomposition temperature (Td showed some variations attributed to the thermal hydrolysis induced by the large amount of adsorbed water and the supplied heat. The glass transition temperature (Tg linearly decreased with both, aw and DP. The microstructural analysis by X-ray diffraction showed that MXs did not crystallize with the adsorption of water, preserving their amorphous structure. The optical micrographs showed radical changes in the overall appearance of the MXs, indicating a transition from a glassy to a rubbery state. Based on these characterizations, different technological applications for the MXs were suggested.

    After years of discussion, debate, and study, the respiratory care curriculum has evolved to a minimum of an associate degree for entry into practice. Although programs are at liberty to offer the entry-level or advanced level associate degree, most are at the advanced level. The most popular site for sponsorship of the associate degree in respiratory care is the community college. The basis for community college sponsorship seems to be its comprehensive curriculum, which focuses on a strong academic foundation in writing, communication, and the basic sciences as well as supporting a career-directed focus in respiratory care. Issues facing the community college are tied to literacy, outcomes, assessment, placement,cooperation with the community, partnerships with industry, and articulation arrangements with granting institutions granting baccalaureate degrees. Community colleges must produce a literate graduate capable of thriving in an information-saturated society. Assessment and placement will intensify as the laissez-faire attitudes toward attendance and allowing students to select courses without any accountability and evaluation of outcome become less acceptable. Students will be required to demonstrate steady progress toward established outcomes. Maintaining relations and cooperation with the local community and the health care industry will continue to be a prominent role for the community college. The challenge facing associate degree education in respiratory care at the community college level is the ability to continue to meet the needs of an expanding professional scope of practice and to provide a strong liberal arts or general education core curriculum. The needs for a more demanding and expanding respiratory care curriculum and for a rich general education core curriculum have led to increased interest in baccalaureate and graduate degree education. The value of associate degree education at the community college level is well established. It is

    1989-03-01

    A statewide study was done with five associate degree (ADN) and five baccalaureate degree (BSN) nursing programs in Georgia to examine the similarities and differences in curriculum based on a nationally used model. From this overall study, select content related to community/home health care was evaluated in the sample programs. Professional standards for community and home health care nursing practice, as well as other published literature on the topic, provided a basis to determine competence to practice. Data were collected through a taped telephone interview to all program chairpersons (N = 10) and mailed questionnaires to faculty involved with all required courses (N = 110). Content analyses of responses allowed for evaluation of frequency of these learning activities between ADN and BSN programs and among BSN programs in the areas of family, teaching, interdisciplinary collaboration, physical assessment, and leadership. Overall, the results indicated lack of conclusive data to support a distinct difference in these educational components between the ADN and BSN sample or among BSN programs. The study was intended to service as a basis for home health care curriculum development in the future.

    In recent years, a number of universities have made sweeping changes in science and engineering education at the graduate level by creating new and innovative curricula interfacing the physical, biological, and computer sciences, along with various engineering disciplines. The primary goal of these educational programs is to train a new generation of researchers who are capable of solving challenging science and engineering problems using parallel computers, high-speed networks, and advanced scientific visualization. LSU has established a dual-degree program that allows students to obtain a Ph.D. in the physical sciences and a M.S. from the Department of Computer Science. In support of this educational program, a multidisciplinary high performance computing and communications curriculum has been introduced, and a parallel-computing and three-dimensional, immersive and interactive visualization environment has been created. Dual-degree students also have extensive opportunities to do internships with scientists at government laboratories, universities, and industry in the US, Europe, and Japan.

  18. Identification of entry-level competencies for associate degree radiographers as perceived by primary role definers

    Thorpe, R.L.

    1981-01-01

    The primary purpose of this study was to identify those competencies needed by Associate Degree Radiographers when they assume employment as entry-level practitioners. A second purpose of the study was to rank order the identified competencies within the role delineations recognized by the Essentials and Guidelines of an Accredited Educational Program for the Radiographer. These role delineations include: radiation protection, exercise discretion and judgment, emergency and life saving techniques, patient care and interpersonal communication, and role as professional member. A third purpose of the study was to examine the degree of consensus on role definition of entry-level competencies needed by Associate Degree Radiographers as perceived by primary role definers (such as employers, employees, and educators), and by other selected variables: age, sex, length of experience in radiologic technology, level of formal education, and place of employment. A major finding of this study was that respondents did not differ significantly in their ranking of entry-level competencies needed by Associate Degree Radiographers when the responses were analyzed according to position, age, sex, length of experience, level of education, or place of employment. Another important finding was that respondents considered all of the 63 competencies as important and needed by Associate Degree Radiographers upon initial employment.A major conclusion and recommendation of this study, in view of the high agreement on the rank ordering of competencies, was that these competencies should be included in a competency-based education model. It was further recommended that a three-way system of communication between employers, employees, and educators be considered in order to pool resources and to increase understanding of each position group's contribution and influence on entry-level Associate Degree Radiographers.

    Full Text Available Problem statement: The current issue on inter-firm technology transfer in the developing countries is centered on the efficiency and effectiveness of the transfer process by the Multinationals (MNCs. Thus, organizations in the developing countries are striving hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs as an efficient mean to increase their competitiveness, technological capabilities and potential for local innovation. Knowledge as the critical element underlying technology has become one of the main factors that affects the success and failure of inter-firm technology transfer within IJVs which is measured by the degree of technology transferred. Based on the underlying knowledge-based view perspective, this paper aims to empirically examine the effect of three critical knowledge characteristics: Tacitness, complexity and specificity on degree of technology transfer and its two dimensions: Degree of tacit and explicit knowledge. Approach: The theoretical model and hypotheses in this study were tested using empirical data gathered from 128 joint venture companies registered with the Registrar of Companies of Malaysia. Data obtained from the survey questionnaires were analyzed using the correlation coefficients and multiple linear regression analyses. Results: The results revealed that tacitness and complexity as two critical elements of knowledge characteristics have significant effects on both degrees of tacit and explicit knowledge; with complexity recording slightly stronger effect than tacitness. However, although specificity has a strong theoretical foundation, it did not record significant effect. Conclusion: The study has bridged the literature gaps in such that it provides empirical evidence on the effects of three generic knowledge attributes: Tacitness, complexity and specificity on degree of inter-firm technology

    Full Text Available Background: As part of control tests taken by students, problems in the use of the language emerged. Therefore, it was uniformly established how to deal with spelling mistakes through the implementation of Instruction 1 / 2009. Objective: To design a spelling course for students in the Health Technology Bachelor Degree. Methods: A descriptive-observational study was conducted from January to March 2010. The sample consisted of 120 first year students. The main methods used were: document analysis, surveys and educational testing. Results: As main causes of spelling mistakes students identified the lack of rules knowledge, the lack of reading habits and little use of the dictionaries. The most frequent mistakes identified in the diagnostic test were: written accent (we are working with Spanish speaking students, changes, omissions or additions and agreement. This course covers a total of 60 hours and emphasizes in six general issues: following the guidelines of Instruction 1 / 2029, starting with a diagnostic test, using a textual approach, promoting mostly practical activities, following productive teaching methods with an emphasis on inductive and deductive procedures and highlighting the systematization of the teaching process as a didactic principle. Conclusions: The design of this course contributes to eliminate spelling mistakes in students.

    Garcia, M.L.

    1997-04-01

    A technology roadmap is the result of a strategic technology planning process that cooperatively identifies (1) a particular industry`s common product and process performance targets, (2) the technology alternatives and milestones for meeting these targets, and (3) a common technology path for research and development activities. The author describes a successful major roadmapping experience - the Semiconductor Industry Association`s Technology Roadmapping Process, which culminated in a workshop held in 1992. The report explains the committee structure and processes that were used both before and after the workshop and presents principles and practices that can aid future technology roadmappers. Appendix 1 summarizes the process from a committee-structure viewpoint. Appendix 2 summarizes the process from a functional view-point. Appendix 3 answers some frequently asked questions about technology roadmapping.

  12. Larger ejaculate volumes are associated with a lower degree of polyandry across bushcricket taxa.

    2006-09-22

    In numerous insects, including bushcrickets (Tettigoniidae), males are known to transfer substances in the ejaculate that inhibit the receptivity of females to further matings, but it has not yet been established whether these substances reduce the lifetime degree of polyandry of the female. The aim of this study was to test the hypothesis that larger ejaculate volumes should be associated with a lower degree of polyandry across tettigoniid taxa, controlling for male body mass and phylogeny. Data on ejaculate mass, sperm number, nuptial gift mass and male mass were taken primarily from the literature. The degree of polyandry for 14 species of European bushcrickets was estimated by counting the number of spermatodoses within the spermathecae of field-caught females towards the end of their adult lifespans. Data for four further species were obtained from the literature. Data were analysed by using both species regression and independent contrasts to control for phylogeny. Multiple regression analysis revealed that, as predicted, there was a significant negative association between the degree of polyandry and ejaculate mass, relative to male body mass, across bushcricket taxa. Nuptial gift size and sperm number, however, did not contribute further to interspecific variation in the degree of polyandry. A positive relationship was found, across bushcricket taxa, between relative nuptial gift size and relative ejaculate mass, indicating that larger nuptial gifts allow the male to overcome female resistance to accepting large ejaculates. This appears to be the first comparative evidence that males can manipulate the lifetime degree of polyandry of their mates through the transfer of large ejaculates.

    Full Text Available Background: To identify the risk factors of fourth-degree laceration during vaginal delivery. Methods: This is a retrospective, case control study. We reviewed 131802 records of vaginal deliveries within 14 years period from 1990 to 2004 in two obstetric center. Cases were 93 vaginal deliveries with fourth-degree laceration and 7 cases were delivered at home, control subjects were 200 vaginal deliveries without third- or fourth-degree lacerations and were identified with the use of random selection. We studied the effects of: maternal age, nationality, parity, gestational age, hour of delivery, birth attendants, episiotomy use and duration of second stage of labor, use of oxytocin, use of forceps or vaccum, Infant birth weight, presentation and postion of fetus, previous severe perineal injury, maternal medical illness and place of delivery. Results: We found 93 cases (%0.07 of documented fourth-degree laceration in 131802 deliveries Conclusion: This study identified several factors associated with fourth-degree laceration. Median episiotomy should be avoided. Nulliparity, fetal macrosomia and OP position are significant risk factors that require caution by birth attendants during delivery

  15. Using the Clark Simulation Evaluation Rubric with associate degree and baccalaureate nursing students.

    Science.gov (United States)

    Gantt, Laura T

    2010-01-01

    As simulation becomes a common teaching strategy in nursing education, faculty struggle with methods for measuring student performance in summative, or evaluative, scenarios. While skills checklists have been shown to be a valid way to quantify performance on many of the technical components of a patient care scenario, nurse educators have also begun to utilize simulation grading rubrics to capture more contextual and critical thinking components. The article describes a pilot study using the Clark Simulation Evaluation Rubric with undergraduate nursing students of different levels from two types of programs. Sixty-nine associate degree and 109 baccalaureate degree students were evaluated and scored in simulation performance using the rubric. The rubric was found to be a practical tool that could potentially be used with or without skills checklists. Future work will involve refining use of the rubric and establishing interrater reliability among faculty who routinely evaluate students using this rubric.

  16. Olfactory Specific Satiety depends on degree of association between odour and food.

    Science.gov (United States)

    Stafford, Lorenzo D

    2016-03-01

    The pleasantness of a food odour decreases when that food is eaten to satiety or even smelled for a brief period (Olfactory Specific Satiety, OSS), which suggests that odours signal food variety and encourage approach behaviour toward novel foods. In the study here, we aimed to extend this theory to understand the consequence of manipulating the food consumed and its degree of association to the evaluated odour. We also wished to clarify if these effects related to individual sensitivity to the target odour. In the study here, participants (n = 94) rated the pleasantness of a food odour (isoamyl acetate) and then consumed confectionary that had either Low or High association to that odour or a No food control. This was followed by final pleasantness ratings for the odour and a threshold sensitivity test. Results revealed that in line with OSS, pleasantness decreased in the High association group only. This effect was not dependent on any differences in sensitivity to the target odour. These findings are consistent with OSS, and that this effect likely depends on activation of brain areas related to odour hedonics rather than the degree to which the odour is detected.

    Full Text Available Objective Investigate binge eating (BE prevalence in women according to the obesity degree and assess the associated factors. Methods Cross-sectional study with female adults presenting body mass index (BMI ≥ 35 kg/m2. The analyzed variables were: sociodemographics, health status, obesity history, lifestyle, eating behavior and obesity degree. In order to analyse BE it was used the Binge Eating Scale (BES, which is considered positive when BES ≥ 18 points. Prevalence and prevalence ratios (PR were calculated with confidence intervals (CI of 95%. Multivariate analysis was carried out using Poisson regression. Results BE prevalence was 53.2%, and the prevalence in super superobese women (BMI ≥ 60 kg/m2 was 75%. After multivariate analysis, associations were observed between the age group 40-49 years old (PR = 2.0; 95% CI = 1.2-3.4 and the “snacking habit” (PR = 1.9; 95% CI = 1.2-2.9. Conclusion The prevalence of BE in severe obese women was high. Association with the “snacking habit” can be a BE marker that should be monitored in the severely obese individuals that fit this profile.

    Because the literature shows that cigarette smoking is a major causative factor in the occurrence of chronic illness, lung cancer is becoming more common in women than breast cancer, nurses smoke more than any other group of health care providers and studies have not examined differences of smoking among the associate degree, undergraduate and diploma levels of nursing, this study was designed to examine selected health behaviours and their relationship to cigarette use among Alabama senior student nurses, and to determine smoking prevalence by level of educational preparation. A sample of senior associate degree, undergraduate and diploma student nurses in Alabama responded to an 87-item questionnaire which was personally administered by the investigator in a classroom setting. Twenty-two of the 87 items were used to compile the demographics, prevalences and health behaviours reported here. The remaining items were used to develop a sequence of information required to test Ajzen and Fishbein's Theory of Reasoned Action and are beyond the scope of this article. Though there was no significant difference of smoking prevalence among educational levels, there was a trend for increased smoking from undergraduate to diploma level with prevalences of: total sample, 26.2%; diploma, 30%; associate degree, 26%; and undergraduate, 24%. Health behaviours which were significantly different between smoking and non-smoking student nurses were breakfast frequency and coffee consumption. Having a regular exercise routine was not significant. Males smoked significantly more than females. More older nurses (over 40 years) smoked than younger nurses. The findings reported here are useful to the development of health education strategies designed to reduce and prevent cigarette use among student nurses.(ABSTRACT TRUNCATED AT 250 WORDS)

    Alon Abraham

    Full Text Available Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP is one of several chronic treatable acquired demyelinating neuropathies.To explore the association between the degree of demyelination in CIDP, and treatment responsiveness.A retrospective chart review of CIDP subjects assessed between 1997 and 2013 was performed to compare treatment responsiveness using different sets of criteria.99 CIDP patients were included, 34 with diabetes mellitus (DM. Treatment responsiveness was higher in CIDP-DM fulfilling 1 or more EFNS/PNS criteria, (63% vs. 31%, p = 0.03, and in CIDP+DM fulfilling 2 or more criteria (89% vs. 36%, p = 0.01. Nonetheless, treatment responsiveness in CIDP+DM had the highest odds ratio (3.73, p = 0.01. Similar results were also shown in simplified uniform study criteria, with 10% cut off values for CIDP-DM, compared to 30% for CIDP+DM.In CIDP+DM, higher degrees of demyelination are associated with treatment responsiveness, implying the need to adjust current criteria in these patients.

    Phytochelatins (PCs) play important role in phytoremediation as heavy metal binding peptides. In the present study, the association between heavy metal removal capacity and phytochelatin synthesis was compared through the examination of three aquatic plants: Elodea canadensis, Salvinia natans and Lemna minor. In case of a Cd treatment, or a Cd treatment combined with Cu and Zn, the highest removal capacity was observed in L. minor. At the same time, E. canadensis showed the lowest removal capacity except for Zn. The heavy metal-induced (Cu+Zn+Cd) oxidative stress generated the highest ascorbate level in L. minor. Cd in itself or combined with the other two metals induced a 10-15-fold increase in the amount of ɣ-glutamylcysteine in L. minor while no or smaller changes were observed in the other two species. Correspondingly, the total PC content was 6-8-fold greater in L. minor. In addition, PCs with higher degree of polymerization were only observed in L. minor (PC4, PC6 and PC7) while PC2 and PC3 occurred in E. canadensis and S. natans only. The correlation analysis indicated that the higher phytoremediation capacity of L. minor was associated with the synthesis of PCs and their higher degree of polymerization.

  3. PCSK6 VNTR Polymorphism Is Associated with Degree of Handedness but Not Direction of Handedness.

    Full Text Available Although the left and right human cerebral hemispheres differ both functionally and anatomically, the mechanisms that underlie the establishment of these hemispheric specializations, as well as their physiological and behavioral implications, remain largely unknown. Since cerebral asymmetry is strongly correlated with handedness, and handedness is assumed to be influenced by a number of genetic and environmental factors, we performed an association study of LRRTM1 rs6733871 and a number of polymorphisms in PCSK6 and different aspects of handedness assessed with the Edinburgh handedness inventory in a sample of unrelated healthy adults (n = 1113. An intronic 33bp variable-number tandem repeat (VNTR polymorphism in PCSK6 (rs10523972 shows a significant association (significance threshold: p<0.0025, adjusted for multiple comparisons with a handedness category comparison (P = 0.0005 and degree of handedness (P = 0.001. These results provide further evidence for the role of PCSK6 as candidate for involvement in the biological mechanisms that underlie the establishment of normal brain lateralization and thus handedness and support the assumption that the degree of handedness, instead the direction, may be the more appropriate indicator of cerebral organization.

    2014-08-01

    The goal of this study was to investigate the potential use ofmoving bed biofilm reactor (MBBR) systems as ammonia removal post-treatment units for wastewater (WW) treatment lagoons that demonstrate large temperature changes throughout their operational year (1 - 20 degrees C). The study was carried out over a six-month period using laboratory-scale MBBR reactors fed with incoming effluent from a full-scale lagoon. The study shows that significant average ammonia removal rates of 0.26 and 0.11 kgN/m . d were achieved at 20 degrees C and 1C. The increase in the ammonia removal rates with increasing temperature from 1 degrees C to 20 degrees C showed a strong correlation to an applied temperature correction coefficient model. No significant accumulation of effluent nitrite was observed at 1 degrees C or after being fed with synthetic wastewater (SWW); indicating that cold temperatures and transitions from real WW to SWW did not stress the nitrifiers. Furthermore, the study demonstrates that changes in temperature or changes from real WW to SWW do not affect the mass of biofilm attached per MBBR carrier. Hence, based on the results of this study, it is concluded that MBBR is a promising technology for post-treatment ammonia removal of WW lagoon effluent.

    High attrition in associate degree nursing (ADN) programs contributes to the nursing shortage and causes hardship for students, families, faculty, colleges, and taxpayers. The purpose of this integrative literature review is to identify admission criteria related to ADN program success to inform evidence-based admission policies and reduce attrition. Integrative review methodology, suggested by Whittemore and Knafl, was used. A systematic search of existing professional literature was conducted using five databases and key word searches. The final sample included 26 documents that were analyzed and synthesized with the matrix method. Five categories of admission criteria and factors related to success in ADN programs were revealed from the analysis of findings: academic aptitude, demographic factors, psychological hardiness, specialty skills and experience, and socioeconomic support. ADN programs with a goal of decreasing attrition may want to implement admission selection guidelines that consider applicant criteria and attributes across all five dimensions.

    The purpose of this study is to examine the relationship between selected admission variables (entrance GPA, ACT subtests scores in English and mathematics, composite ACT scores), age, perception of role strain, achievement in clinical and nursing courses, achievement on NLN examinations, exit GPA, and performance on NCLEX-RN examination. Data were attained from records of 146 associate degree graduates who were admitted to a specially-designed associate degree program in nursing and on those graduates who wrote the NCLEX-RN examination in July 1987 and July 1988. Pearson product moment correlations and stepwise multiple regression analyses were used to identify the relationship between the predictor variables (admission criteria, age, perception of role strain, achievement in clinical and nursing courses), achievement on NLN examinations, exit GPA, and the criterion variable (scores on the NCLEX-RN examination). The best predictor for performance on the NCLEX-RN of the selected admission variables, age, perception of role strain, and exit GPA, were exit GPA (R = .71) and ACT composite scores (R = .75). The ACT math, ACT English scores, entrance GPA, age, and perception of role strain, had no predictive value. The best predictor for performance on the NCLEX-RN of nursing theory course and clinical course grades were the two theory courses in the second year of the program NUR 2712 (R = .77) and NUR 2713 (R = .79). NUR 2711 and 2711L, NUR 2712L, 2713L, and 2813 had no predictive value for success on the NCLEX-RN.(ABSTRACT TRUNCATED AT 250 WORDS)

Method After Institutional Board approval, 171 consecutive patients were retrospectively enrolled, 105 LSS patients and 66 patients without stenosis. The dural sac cross-sectional area (CSA was measured on T2w axial MRI at the level of L2-3, L3-4 and L4-5 intervertebral discs. Two blinded radiologists classified cases as exhibiting or not RNRCE in MRI. Intra- and inter-observer reproducibility was assessed. Results RNRCE were associated with LSS. RRNCE was more frequent when maximum stenosis<55 mm2. Substantial intra- observer agreement and moderate inter-observer agreement were obtained in the classification of RNRCE. Spondylolisthesis was identified in 27 patients and represented increased risk for RRNCE. Conclusion LSS is a risk factor for RNRCE, especially for dural sac CSA<55 mm2. LSS and spondylolisthesis are independent risk factors for RNRCE.

Serum samples were obtained to determine circulating TNF-α, IL-8, and VEGF. Univariate and bivariate analysis (chi square, fisher’s exact, and mann-whitney test were done using SPSS version-22. Results: there were 41.25% of 80 patients infected with Helicobacter pylori. Serum TNF-α and VEGF levels in the infected group were significantly higher compared to H. pylori negative, but there were no significant differences between serum levels of IL-8 in H. pylori positive and negative. There were significant associations between serum level of TNF-α and IL-8 with degree of chronic inflammation, and also between serum level of IL-8 and degree of neutrophil infiltration. There were significant associations between serum level of VEGF and degree of atrophy, and also between serum level of VEGF and degree of intestinal metaplasia. Conclusion: High levels of TNF-α were associated with severe degree of chronic inflammation, high levels of IL-8 associated with severe degree of chronic inflammation and neutrophil infiltration, and high levels of VEGF associated with severe degree of premalignant gastric lesion. Key words: cytokine, neoangiogenesis, Helicobacter pylori, atrophic gastritis, intestinal metaplasia.

  17. Development and Implementation of Degree Programs in Electric Drive Vehicle Technology

    2013-09-30

    The Electric-drive Vehicle Engineering (EVE) MS degree and graduate certificate programs have been continuing to make good progress, thanks to the funding and the guidance from DOE grant management group, the support from our University and College administrations, and to valuable inputs and feedback from our Industrial Advisory Board as well as our project partners Macomb Community College and NextEnergy. Table 1 below lists originally proposed Statement of Project Objectives (SOPO), which have all been completed successfully. Our program and course enrollments continue to be good and increasing, as shown in later sections. Our graduating students continue to get good job offers from local EV-related companies. Following the top recommendation from our Industrial Advisory Board, we were fortunate enough to be accepted into the prestigious EcoCAR2 (http://www.ecocar2.org/) North America university design competition, and have been having some modest success with the competition. But most importantly, EcoCAR2 offers the most holistic educational environment for integrating real-world engineering and design with our EVE graduate curriculum. Such integrations include true real-world hands-on course projects based on EcoCAR2 related tasks for the students, and faculty curricular and course improvements based on lessons and best practices learned from EcoCAR2. We are in the third and last year of EcoCAR2, and we have already formed a core group of students in pursuit of EcoCAR”3”, for which the proposal is due in early December.

    Context. The Kilo-Degree Survey (KiDS) is an ongoing optical wide-field imaging survey with the OmegaCAM camera at the VLT Survey Telescope. It aims to image 1500 square degrees in four filters (ugri). The core science driver is mapping the large-scale matter distribution in the Universe, using weak lensing shear and photometric redshift measurements. Further science cases include galaxy evolution, Milky Way structure, detection of high-redshift clusters, and finding rare sources such as strong lenses and quasars. Aims: Here we present the third public data release and several associated data products, adding further area, homogenized photometric calibration, photometric redshifts and weak lensing shear measurements to the first two releases. Methods: A dedicated pipeline embedded in the Astro-WISE information system is used for the production of the main release. Modifications with respect to earlier releases are described in detail. Photometric redshifts have been derived using both Bayesian template fitting, and machine-learning techniques. For the weak lensing measurements, optimized procedures based on the THELI data reduction and lensfit shear measurement packages are used. Results: In this third data release an additional 292 new survey tiles (≈300 deg2) stacked ugri images are made available, accompanied by weight maps, masks, and source lists. The multi-band catalogue, including homogenized photometry and photometric redshifts, covers the combined DR1, DR2 and DR3 footprint of 440 survey tiles (44 deg2). Limiting magnitudes are typically 24.3, 25.1, 24.9, 23.8 (5σ in a 2'' aperture) in ugri, respectively, and the typical r-band PSF size is less than 0.7''. The photometric homogenization scheme ensures accurate colours and an absolute calibration stable to ≈2% for gri and ≈3% in u. Separately released for the combined area of all KiDS releases to date are a weak lensing shear catalogue and photometric redshifts based on two different machine

    2016-11-01

    The effects of sodium tripolyphosphate (STPP), two sources of starch (potato starch: PS and rice starch: RS) and comminution degree (CD) on the technological, instrumental and sensory characteristics of reformed hams were studied using response surface methodology. Both starches reduced cook loss and decreased ham flavour intensity, but RS had stronger effects on instrumental measures of texture, while PS was associated with improved juiciness when low/no added STPP was included. Coarsely ground meat, processed 100% with the kidney plate was associated with slightly increased cook loss, reduced texture profile analysis parameters and a more intense ham flavour compared to the other treatment (80% ground with a kidney plate plus 20% with a 9mm plate). STPP was the sole factor affecting overall liking. If starch is included in the formulation, the standard level of STPP (0.3%) can be reduced by half with no increase in cook losses, but some decline in sensory quality cannot be avoided.

  3. Generational diversity in associate degree nursing students: Teaching styles and preferences in Pennsylvania

    2011-12-01

    Nursing educators face the challenge of meeting the needs of a multi-generational classroom. The reality of having members from the Veteran and Baby Boomer generations in a classroom with Generation X and Y students provides an immediate need for faculty to examine students' teaching method preferences as well as their own use of teaching methods. Most importantly, faculty must facilitate an effective multi-generational learning environment. Research has shown that the generation to which a person belongs is likely to affect the ways in which he/she learns (Hammill, 2005). Characterized by its own attitudes, behaviors, beliefs, and motivational needs, each generation also has distinct educational expectations. It is imperative, therefore, that nurse educators be aware of these differences and develop skills through which to communicate with the different generations, thereby reducing teaching/learning problems in the classroom. This is a quantitative, descriptive study that compared the teaching methods preferred by different generations of associate degree nursing students with the teaching methods that the instructors actually use. The research study included 289 participants; 244 nursing student participants and 45 nursing faculty participants from four nursing departments in colleges in Pennsylvania. Overall, the results of the study found many statistically significant findings. The results of the ANOVA test revealed eight statistically significant findings among Generation Y, Generation X and Baby boomers. The preferred teaching methods included: lecture, self-directed learning, web-based course with no class meetings, important for faculty to know my name, classroom structure, know why I am learning what I am learning, learning for the sake of learning and grade is all that matters. Lecture was found to be the most frequently used teaching method by faculty as well as the most preferred teaching methods by students. Overall, the support for a variety of

    2010-01-01

    This article reports on a survey of associate degree and diploma nursing students in Pennsylvania designed to elicit their future educational goals and opinions regarding proposed educational advancement legislation. Results indicated the majority of respondents (86.3 percent) planned to pursue the bachelor's degree in nursing; most (94.8 percent) hoped to be enrolled in a BSN program within four years of graduation. The majority (78.9 percent) indicated that even if they were mandated to complete the bachelor's degree in nursing within 10 years, they would still enroll in their current associate degree or diploma program. Asked if 10 years is a reasonable amount of time to complete the BSN, 79.4 percent agreed it is. If money were not an obstacle, 95.8 percent of participants indicated they would pursue a BSN or higher. The results of this survey suggest that the vast majority of associate degree and diploma nursing students value and hope to pursue higher education in nursing.

  16. Additional degrees of freedom associated with position measurements in non-commutative quantum mechanics

    CERN Document Server

    Rohwer, CM

    2012-01-01

    In this thesis we shall demonstrate that a measurement of position alone in non-commutative space cannot yield complete information about the quantum state of a particle. Indeed, the formalism used entails a description that is non-local in that it requires all orders of positional derivatives through the star product that is used ubiquitously to map operator multiplication onto function multiplication in non-commutative systems. It will be shown that there exist several equivalent local descriptions, which are arrived at via the introduction of additional degrees of freedom. Consequently non-commutative quantum mechanical position measurements necessarily confront us with some additional structure which is necessary to specify quantum states completely. The remainder of the thesis, will involve investigations into the physical interpretation of these additional degrees of freedom. For one particular local formulation, the corresponding classical theory will be used to demonstrate that the concept of extended...

    Sixty-two Ss learned six CCC trigram-digit pairs by the study-test method; 21 Ss continued the PA acquisition trials to a learning criterion of one errorless trial, while 41 Ss were carded to 300% overlearning or 24 trials, whichever came first. The Ss were then shown individual letters of the trigrams, with position cues provided, and were tested for their ability to provide the digit and produce the additional letters. Digit recall was much better to initial letters than to those in the second or third positions of the trigrams; with oveflearning, digit recall improved to the initial letters but not to letters in second and third positions. Production of additional letters of the trigrams was not appreciably related to either cue position or degree of PA learning. There was some evidence ofincreased selectivity with higher degrees of PA learning.

    2013-01-01

    Associating environmental stresses (ESs) with built-in test (BIT) output is an important means to help diagnose intermittent faults (IFs).Aiming at low efficiency in association of traditional time stress measurement device (TSMD),an association model is built.Thereafter,a novel approach is given to evaluate the integrated environmental stress (IES) level.Firstly,the selection principle and approach of main environmental stresses (MESs) and key characteristic parameters (KCPs) are presented based on fault mode,mechanism,and ESs analysis (FMMEA).Secondly,reference stress events (RSEs) are constructed by dividing IES into three stress levels according to its impact on faults; and then the association model between integrated environmental stress event (IESE) and BIT output is built.Thirdly,an interval grey association approach to evaluate IES level is proposed due to the interval number of IES value.Consequently,the association output can be obtained as well.Finally,a case study is presented to demonstrate the proposed approach.Results show the proposed model and approach are effective and feasible.This approach can be used to guide ESs measure,record,and association.It is well suited for on-line assistant diagnosis of faults,especially IFs.

  4. Cognitive alexithymia is associated with the degree of risk for psychosis.

    Directory of Open Access Journals (Sweden)

    Jorien van der Velde

    Full Text Available Alexithymia is a personality construct denoting emotion processing problems. It has been suggested to encompass two dimensions: a cognitive and affective dimension. The cognitive dimension is characterized by difficulties in identifying, verbalizing and analyzing emotions, while the affective dimension reflects the level of emotional arousal and imagination. Alexithymia has been previously proposed as a risk factor for developing psychosis. More specifically, the two alexithymia dimensions might be differentially related to the vulnerability for psychosis. Therefore, we examined the two dimensions of alexithymia, measured with the BVAQ in 94 siblings of patients with schizophrenia, 52 subjects at ultra-high risk (UHR for developing psychosis, 38 patients with schizophrenia and 109 healthy controls. The results revealed that siblings and patients had higher levels of cognitive alexithymia compared to controls. In addition, subjects at UHR for psychosis had even higher levels of cognitive alexithymia compared to the siblings. The levels of affective alexithymia in siblings and patients were equal to controls. However, UHR individuals had significantly lower levels of affective alexithymia (i.e. higher levels of emotional arousal and fantasizing compared to controls. Alexithymia was further related to subclinical levels of negative and depressive symptoms. These findings indicate that alexithymia varies parametrically with the degree of risk for psychosis. More specifically, a type-II alexithymia pattern, with high levels of cognitive alexithymia and normal or low levels of affective alexithymia, might be a vulnerability factor for psychosis.

  8. Association of extensive myelinated nerve fibers and high degree myopia: Case report

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Unilateral extensive myelination of the peripapillary nerve fibers may be associated with anisometropic myopia, strabismus, and reduced vision. Myelination of optic nerve fibers terminate at lamina cribrosa. Yet in some patients, myelination progresses into the peripapillary retinal nerve fibers and may affect the visual acuity. In this report, we described 4 patients. All patients presented extensive peripapillary myelinated nerve fibers associated with myopic anisometropia. After routine ophthalmic and orthoptic examinations, all patients underwent treatment for amblyopia through correction with spectacles, contact lenses, and the occlusion of the good eye. Corrected visual acuity improved in 1 patient, but 3 patients had no increase in visual acuity despite treatment with full cycloplegic refraction and appropriate patching. Probably because of structural abnormalies of the macula, visual results are often disappointing with appropriate correction of the refractive error and occlusion.

    Background Anhedonia is a cardinal feature of major depression and is hypothesized to be driven by low motivation, in particular blunted reward sensitivity. It has been suggested to be a marker that represents a genetic predisposition to this disorder. However, little is known about the mechanisms underlying this heightened risk in unaffected first-degree relatives of patients with major depression. We previously demonstrated abnormal reward biases in acutely depressed patients. The present study aimed to examine the development of reward bias in first-degree relatives of patients with major depression. Methods Forty-seven first-degree relatives of patients with major depression (26 females, age 18-52) and 60 healthy controls with no family history of depression (34 females, age 21-48) were recruited. A probabilistically rewarded difficult visual discrimination task, in which participants were instructed about the contingencies, was used to assess blunted reward sensitivity. A response bias towards the more frequently rewarded stimulus (termed “reward bias”) was the primary outcome variable in this study. Participants also completed self-reported measures of anhedonia and depressive symptoms. Results Compared with the control group, relatives of patients with major depression with sub-clinical depressive symptoms displayed a blunted reward bias. Relatives without symptoms displayed largely intact motivational processing on both self-report and experimental measures. The degree of anhedonia was associated with attenuated reward bias in first-degree relatives of patients with major depression, especially in those with sub-clinical symptoms. Limitations The study did not include a depressed patient group, which restricted our ability to interpret the observed group differences. Conclusions Blunted reward sensitivity may be largely manifested in a subgroup of relatives with high levels of depressive symptoms. PMID:26590511

    In this study biodegradation of hydrocarbons in thin oil films was investigated in seawater at low temperatures, 0 and 5 degrees C. Heterotrophic (HM) or oil-degrading (ODM) microorganisms enriched at the two temperatures showed 16S rRNA sequence similarities to several bacteria of Arctic or Antarctic origin. Biodegradation experiments were conducted with a crude mineral oil immobilized as thin films on hydrophobic Fluortex adsorbents in nutrient-enriched or sterile seawater. Chemical and respirometric analysis of hydrocarbon depletion showed that naphthalene and other small aromatic hydrocarbons (HCs) were primarily biodegraded after dissolution to the water phase, while biodegradation of larger polyaromatic hydrocarbons (PAH) and C(10)-C(36) n-alkanes, including n-hexadecane, was associated primarily with the oil films. Biodegradation of PAH and n-alkanes was significant at both 0 and 5 degrees C, but was decreased for several compounds at the lower temperature. n-Hexadecane biodegradation at the two temperatures was comparable at the end of the experiments, but was delayed at 0 degree C. Investigations of bacterial communities in seawater and on adsorbents by PCR amplification of 16S rRNA gene fragments and DGGE analysis indicated that predominant bacteria in the seawater gradually adhered to the oil-coated adsorbents during biodegradation at both temperatures. Sequence analysis of most DGGE bands aligned to members of the phyla Proteobacteria (Gammaproteobacteria) or Bacteroidetes. Most sequences from experiments at 0 degree C revealed affiliations to members of Arctic or Antarctic consortia, while no such homology was detected for sequences from degradation experiment run at 5 degrees C. In conclusion, marine microbial communities from cold seawater have potentials for oil film HC degradation at temperatures bacteria may play an important role during oil HC biodegradation in seawater close to freezing point.

    2004-07-01

    The present article outlines the diverse possibilities afforded by present-day technology for treating the fermentable organic fraction, depending on the homogeneity of the waste collected. In accordance with the degree of contamination of the initial waste, the different possible processes for treating the organic matter are described: pasteurisation, for the very clean and homogeneous waste, composting and methanization depending on the greeter degree of contamination of the initial waste. Nevertheless, technologies based on methanization or anaerobic digestion also have at their limits regarding the presence of contaminants and the current trend for more problematic waste is their use in the manufacture of bio fuels, Finally, reference is made to the different thermal treatment technologies.

    The objective of this paper is to examine whether smoking is associated with autoantibody production in systemic lupus erythematosus (SLE) patients, unaffected first-degree relatives (FDR) of individuals with SLE--a group at increased risk of developing SLE--or unaffected, unrelated controls. Detailed demographic, environmental, clinical, and therapeutic information was collected by questionnaire on 1242 SLE patients, 981 FDRs, and 946 controls in the Lupus Family Registry and Repository; a blood sample was obtained. All sera were tested for multiple lupus autoantibodies by immunofluorescence and luminex bead-based assays. Generalized estimating equations, adjusting for age, gender, and ethnicity and accounting for correlation within families, were used to assess smoking status with the dichotomous outcome variables of positivity for SLE status, positivity of ANA by immunofluorescence (≥1:120), positivity for ≥1 autoantibody by the luminex assay, and positivity for each of the 11 autoantibodies. Current smoking was associated with being positive for ≥1 autoantibody (excluding ANA) (adjusted OR = 1.53, 95% CI 1.04-2.24) in our subjects with SLE. No association was observed in unaffected FDRs or healthy controls. Former smoking was associated with anti-Ro/SS-A60 in our unaffected FDRs. There was an increased association with anti-nRNP A seropositivity, as well as a decreased association with anti-nRNP 68 positivity, in current smokers in SLE subjects. No clear association between smoking status and individual autoantibodies was detected in SLE patients, unaffected FDRs, nor healthy controls within this collection. The association of smoking with SLE may therefore manifest its risk through mechanisms outside of autoantibody production, at least for the specificities tested.

    There is an increasing demand from automotive, aircraft and space industry for reliable high temperature resistant electronics. Circuits with reliable functionality up to temperatures of 250 degree(s)C would be sufficient for most of these applications. Digital standard cells and operational amplifiers are the basic building blocks of these circuits. Commercially available digital standard cell libraries and operational amplifiers are normally specified for operation up to a maximum temperature of 125 degree(s)C. Hence, the purpose of this work was the design and characterization of digital standard cells and operational amplifiers for operation up to 250 degree(s)C using a low-cost 1.0 micrometers epi-CMOS process. Several design measures were applied to the cells in order to further improve latch-up resistivity and to limit leakage currents, respectively. The transfer curves of all digital cells for all input signal combinations have been recorded in the temperature range from 30 to 250 degree(s)C. Significant results are very low temperature shifts of the noise margins and of the switching point, respectively. Furthermore, the low (0 V) and high (5 V) levels are reached exactly over the entire temperature range. Outstanding characteristics of the operational amplifier comprise low open-loop gain temperature drift as well as low offset and offset temperature drift, respectively. The open-loop gain was greater than 83 dB at room temperature with a drift of less than 0.02 dB/ degree(s)C. The offset voltage amounted to -1 mV at room temperature and 1 mV at 250 degree(s)C, respectively. The long-term behavior of these cells is currently under investigation.

    Graft hypertrophy is a common occurrence after periosteal, collagen-covered and matrix-induced autologous chondrocyte implantation (MACI). The purpose of this study was to investigate the incidence, development, and degree of graft hypertrophy at 24 months after MACI. The hypothesis was that graft hypertrophy would not be associated with clinical outcome at 24 months. Case series, Level of evidence, 4. This study was undertaken in 180 consecutive patients (113 male, 67 female) after MACI in the knee. All patients were assessed clinically using the Knee injury and Osteoarthritis Outcome Score (KOOS) and underwent magnetic resonance imaging (MRI) at 3, 12, and 24 months after surgery. The incidence of hypertrophy relevant to anatomic graft site was investigated, as was the progressive change in hypertrophic studies postoperatively. The degree of tissue overgrowth in hypertrophic cases was investigated, as was its association with patient clinical outcome at 24 months after surgery. Of the 180 patients, 50 demonstrated a hypertrophic graft at 1 or more postoperative time points. This included 9 grafts (5.0%) at 3 months and 32 grafts (18.7%) at 12 months. At 24 months, 47 grafts (26.1%)-43 (32.1%) tibiofemoral and 4 (8.7%) patellofemoral-were hypertrophic. Patients with hypertrophic grafts at 24 months (n = 47) were younger (P = .051), they had a lower body mass index (BMI; P = .069), and significantly fewer of them had patellofemoral grafts (P = .007) compared with patients who had grafts with full (100%) tissue infill (n = 61). There were no significant differences in any of the KOOS subscales between patients with graft hypertrophy or full (100%) tissue infill at 24 months after surgery, while the severity of graft hypertrophy was not associated with KOOS subscales at 24 months. Hypertrophic grafts after MACI were common and continued to develop through to 24 months after surgery. Hypertrophic growth was associated with being younger and having a lower BMI, was

    Roughly 40% of the nearly 3 million registered nurses (RNs) in the United States have an associate's degree (ADN) as their highest level of nursing education. Yet even before the recent Institute of Medicine report on The Future of Nursing, employers of RNs have increasingly preferred baccalaureate-prepared RNs (BSNs), at least anecdotally. Data from the American Community Survey (2003-2013) were analyzed with respect to employment setting, earnings, and employment outcomes of ADN and BSN-prepared RNs. The data reveal a divergence in employment setting: the percentage of ADN-prepared RNs employed in hospitals dropped from 65% to 60% while the percentage of BSN-prepared RNs employed in hospitals grew from 67% to 72% over this period. Many ADNs who would have otherwise been employed in hospitals seem to have shifted to long-term care settings.

    Thomas Wurster

    Full Text Available BACKGROUND AND PURPOSE: Platelet surface expression of stromal-cell-derived factor-1 (SDF-1 is increased during platelet activation and constitutes an important factor in hematopoetic progenitor cell trafficking at sites of vascular injury and ischemia. Enhanced platelet SDF-1 expression has been reported previously in patients suffering from acute coronary syndrome (ACS. We hypothesized that expression of platelet associated SDF-1 may also be influenced by calcified valvular aortic stenosis (AS. METHODS: We consecutively evaluated 941 patients, who were admitted to the emergency department with dyspnea and chest pain. Platelet surface expression of SDF-1 was determined by flow cytometry, AS was assessed using echocardiography and hemodynamic assessment by heart catheterization. A 1∶1 propensity score matching was implemented to match 218 cases with 109 pairs adjusting for age, sex, cardiovascular risk factors, and medication including ACE inhibitors, angiotensin receptor blockers, beta blockers, statins, aspirin, clopidogrel, GPIIb/IIIa antagonists, and vitamin K antagonists. RESULTS: Patients with valvular AS showed enhanced platelet SDF-1 expression compared to patients without AS (non-valvular disease, NV independent of ACS and stable coronary artery disease (SAP [mean fluorescence intensity (MFI for ACS (AS vs. NV: 75±40.4 vs. 39.5±23.3; P = 0.002; for SAP (AS vs. NV: 54.9±44.6 vs. 24.3±11.2; P = 0.008]. Moreover, the degree of AS significantly correlated with SDF-1 platelet surface expression (r = 0.462; P = 0.002. CONCLUSIONS: Valvular AS is associated with enhanced platelet-SDF-1 expression; moreover the degree of valvular AS correlates with SDF-1 platelet surface expression. These findings may have clinical implications in the future.

    It aimed to explore the degree of difficulty of caries-detection-associated-topics perceived by dental students and lecturers as pedagogical step in the development of learning objects for e-learning. A convenience sample comprising ninety-eight subjects from different academic levels (undergraduate/graduate students and pediatric dentistry lecturers) participated. Two spreadsheets (isolated/relative) were created considering key topics in the caries detection process. The isolated evaluation intended to explore each topic in an isolated way, while the relative intended to classify, comparatively, the participants' perceived difficulty per topic. Afterwards, data were analyzed. All values on spreadsheets were combined obtaining the subject's final perception. Associations between the subjects' degree of the perceived difficulty and academic level were estimated. ANOVA was used to determine differences regarding the perception among evaluated topics in distinct groups. Caries histopathology and detection of proximal carious lesions were the topics perceived as the most difficult in the process of caries detection by both students and lecturers. Differentiation between an extrinsic pigmentation and a brown-spot (caries lesion) as well as differential diagnosis between caries and enamel developmental defects or non-carious lesions were considered as more difficult by undergraduates in comparison to graduates/lecturers (regression-coefficient=14.54; Standard Error=3.34; PTopics as histopathology and detection of proximal caries lesions were identified as the most difficult despite the academic level. However, some topics are differently perceived according to the group. These results are useful for developing pedagogical material, based on the students real learning needs/expectations.

    Genome-wide association studies (GWAS), in which thousands of single-nucleotide polymorphisms (SNPs) spanning the genome are genotyped in individuals who are phenotypically well characterized, -currently represent the most popular strategy for identifying gene regions associated with common -diseases and related quantitative traits. Improvements in technology and throughput capability, development of powerful statistical tools, and more widespread acceptance of pooling-based genotyping approaches have led to greater utilization of GWAS in human genetics research. However, important considerations for optimal experimental design, including selection of the most appropriate genotyping platform, can enhance the utility of the approach even further. This chapter reviews experimental and technological issues that may affect the success of GWAS findings and proposes strategies for developing the most comprehensive, logical, and cost-effective approaches for genotyping given the population of interest.

    Although more than half a century is passed since space technology was first developed, developing countries are just beginning to enter the arena, focusing mainly on educating professionals. Space technology by itself is an interdisciplinary science, is costly, and developing at a fast pace. Moreover, a fruitful education system needs to remain dynamic if the quality of education is the main concern, making it a complicated system. This paper makes use of the System Engineering Approach and the experiences of developed countries in this area while incorporating the needs of the developing countries to devise a comprehensive program in space engineering at the Master's level. The needs of the developing countries as regards space technology education may broadly be put into two categories: to raise their knowledge of space technology which requires hard work and teamwork skills, and to transfer and domesticate space technology while minimizing the costs and maximizing its effectiveness. The requirements of such space education system, which include research facilities, courses, and student projects are then defined using a model drawn from the space education systems in universities in North America and Europe that has been modified to include the above-mentioned needs. Three design concepts have been considered and synthesized through functional analysis. The first one is Modular and Detail Study which helps students specialize in a particular area in space technology. Second is referred to as Integrated and Interdisciplinary Study which focuses on understanding and development of space systems. Finally, the third concept which has been chosen for the purpose of this study, is a combination of the other two, categorizing the required curriculum into seven modules, setting aside space applications. This helps students to not only specialize in one of these modules but also to get hands-on experience in a real space project through participation in summer group

    Full Text Available Abstract Background Diabetes is a chronic medical condition accompanied by a considerable health-related quality of life (HRQL burden. The purpose of this analysis was to use generic measures of HRQL to describe HRQL deficits associated with varying degrees of severity of type 2 diabetes. Methods The RAND-12 physical and mental health composites (PHC and MHC, respectively and Health Utilities Index Mark 3 (HUI3 were self-completed by 372 subjects enrolled in a prospective, controlled study of an intervention to improve care for individuals with type 2 diabetes in rural communities. Analysis of covariance was used to assess differences in HRQL according to disease severity and control of blood glucose. Disease severity was defined in terms of treatment intensity, emergency room visits and absenteeism from work specifically attributable to diabetes. To control for potential confounding, the analysis was adjusted for important sociodemographic and clinical characteristics. Results The PHC and MHC were significantly lower for individuals treated with insulin as compared to diet alone (PHC: 41.01 vs 45.11, MHC: 43.23 vs 47.00, p Conclusions We concluded that generic measures of HRQL captured deficits associated with more severe disease in type 2 diabetes.

    Left ventricular (LV) hypertrophy is a physiological or pathological response of LV myocardium to increased cardiac load. We aimed at investigating and comparing hemodynamic alterations in well-established rat models of physiological hypertrophy (PhyH) and pathological hypertrophy (PaH) by using LV pressure-volume (P-V) analysis. PhyH and PaH were induced in rats by swim training and by abdominal aortic banding, respectively. Morphology of the heart was investigated by echocardiography. Characterization of cardiac function was completed by LV P-V analysis. In addition, histological and molecular biological measurements were performed. Echocardiography revealed myocardial hypertrophy of similar degree in both models, which was confirmed by post-mortem heart weight data. In aortic-banded rats we detected subendocardial fibrosis. Reactivation of fetal gene program could be observed only in the PaH model. PhyH was associated with increased stroke volume, whereas unaltered stroke volume was detected in PaH along with markedly elevated end-systolic pressure values. Sensitive indexes of LV contractility were increased in both models, in parallel with the degree of hypertrophy. Active relaxation was ameliorated in athlete's heart, whereas it showed marked impairment in PaH. Mechanical efficiency and ventriculo-arterial coupling were improved in PhyH, whereas they remained unchanged in PaH. Myocardial gene expression of mitochondrial regulators showed marked differences between PaH and PhyH. We provided the first comparative hemodynamic characterization of PhyH and PaH in relevant rodent models. Increased LV contractility could be observed in both types of LV hypertrophy; characteristic distinction was detected in diastolic function (active relaxation) and mechanoenergetics (mechanical efficiency), which might be explained by mitochondrial differences.

    Full Text Available INTRODUCTION: Advanced glycation endproducts (AGEs may be involved in the development of atherosclerosis, beyond diabetes and renal disease. Skin autofluorescence (AF is a non-invasive marker for AGEs. We examined whether skin AF is increased in (subclinical atherosclerosis and associated with the degree of atherosclerosis independent of diabetes and renal function. METHODS: A cross-sectional study of 223 patients referred for primary (n = 163 or secondary (n = 60 prevention between 2006 and 2012 was performed. Skin AF was measured using the AGE-Reader. Ultrasonography was used to assess plaques in carotid and femoral arteries and computed tomography for the calculation of the coronary artery calcium score (CACS; in primary prevention only. Primary prevention patients were divided into a group with subclinical atherosclerosis defined as >1 plaque or CACS>100 (n = 67; age 53 year [interquartile range 48-56]; 49% male and without (controls; 96; 43 [38-51]; 55%. Secondary prevention were patients with peripheral arterial disease (60; 64 [58-70]; 73%. RESULTS: Skin AF was higher in subclinical and clinical atherosclerosis compared with controls (skin AF 2.11 [interquartile range 1.83-2.46] and 2.71 [2.15-3.27] vs. 1.87 [1.68-2.12] respectively; P = 0.005 and <0.001. In a multivariate analysis, the association of skin AF with the atherosclerosis categories was independent of age, sex, diabetes, presence of the metabolic syndrome, Framingham Risk Score, and renal function. Skin AF correlated with most cardiovascular risk factors, Framingham risk score, and IMT and CACS. CONCLUSIONS: Skin AF is increased in documented subclinical and clinical atherosclerosis, independent of known risk factors such as diabetes and renal disease. These data suggest that AGEs may be associated with the burden of atherosclerosis and warrant a prospective study to investigate its clinical usability as a risk assessment tool for primary prevention.

    ABSTRACT Objective: To determine the presence of staphylococcal superantigen-specific IgE antibodies and degree of IgE-mediated sensitization, as well as whether or not those are associated with the severity of asthma in adult patients. Methods: This was a cross-sectional study involving outpatients with asthma under treatment at a tertiary care university hospital in the city of Rio de Janeiro, Brazil. Consecutive patients were divided into two groups according to the severity of asthma based on the Global Initiative for Asthma criteria: mild asthma (MA), comprising patients with mild intermittent or persistent asthma; and moderate or severe asthma (MSA). We determined the serum levels of staphylococcal toxin-specific IgE antibodies, comparing the results and performing a statistical analysis. Results: The study included 142 patients: 72 in the MA group (median age = 46 years; 59 females) and 70 in the MSA group (median age = 56 years; 60 females). In the sample as a whole, 62 patients (43.7%) presented positive results for staphylococcal toxin-specific IgE antibodies: staphylococcal enterotoxin A (SEA), in 29 (20.4%); SEB, in 35 (24.6%); SEC, in 33 (23.2%); and toxic shock syndrome toxin (TSST), in 45 (31.7%). The mean serum levels of IgE antibodies to SEA, SEB, SEC, and TSST were 0.96 U/L, 1.09 U/L, 1.21 U/L, and 1.18 U/L, respectively. There were no statistically significant differences between the two groups in terms of the qualitative or quantitative results. Conclusions: Serum IgE antibodies to SEA, SEB, SEC, and TSST were detected in 43.7% of the patients in our sample. However, neither the qualitative nor quantitative results showed a statistically significant association with the clinical severity of asthma. PMID:27812635

    Conflicting evidence exists regarding relationships among sitting posture, factors that influence sitting posture, and back pain. This conflicting evidence may partially be due to the presence of multiple and overlapping factors associated with both sitting posture and back pain. The purpose of this study was to determine whether the degree of slump in sitting was associated with sex and other physical, lifestyle, or psychosocial factors. Additionally, the relationship between the report of back pain made worse by sitting and the degree of slump in sitting and other physical, lifestyle, or psychosocial factors was investigated. This was a cross-sectional study. Adolescents (n=1,596) completed questionnaires to determine lifestyle and psychosocial profiles and the experience of back pain. Sagittal sitting posture, body mass index (BMI), and back muscle endurance (BME) were recorded. Standing posture subgroup categorization was determined. Multivariate analysis revealed that the most significant factor associated with the degree of slump in sitting was male sex, followed by non-neutral standing postures, lower perceived self-efficacy, lower BME, greater television use, and higher BMI. Multivariable analysis indicated poorer Child Behaviour Checklist scores were the strongest correlate of report of back pain made worse by sitting, whereas degree of slump in sitting, female sex, and BME were more weakly related. Causality cannot be determined from this cross-sectional study, and 60% of sitting posture variation was not explained by the measured variables. Slump in sitting was associated with physical correlates, as well as sex, lifestyle, and psychosocial factors, highlighting the complex, multidimensional nature of usual sitting posture in adolescents. Additionally, this study demonstrated that a greater degree of slump in sitting was only weakly associated with adolescent back pain made worse by sitting after adjustment for other physical and psychosocial factors.

    To determine the presence of staphylococcal superantigen-specific IgE antibodies and degree of IgE-mediated sensitization, as well as whether or not those are associated with the severity of asthma in adult patients. This was a cross-sectional study involving outpatients with asthma under treatment at a tertiary care university hospital in the city of Rio de Janeiro, Brazil. Consecutive patients were divided into two groups according to the severity of asthma based on the Global Initiative for Asthma criteria: mild asthma (MA), comprising patients with mild intermittent or persistent asthma; and moderate or severe asthma (MSA). We determined the serum levels of staphylococcal toxin-specific IgE antibodies, comparing the results and performing a statistical analysis. The study included 142 patients: 72 in the MA group (median age = 46 years; 59 females) and 70 in the MSA group (median age = 56 years; 60 females). In the sample as a whole, 62 patients (43.7%) presented positive results for staphylococcal toxin-specific IgE antibodies: staphylococcal enterotoxin A (SEA), in 29 (20.4%); SEB, in 35 (24.6%); SEC, in 33 (23.2%); and toxic shock syndrome toxin (TSST), in 45 (31.7%). The mean serum levels of IgE antibodies to SEA, SEB, SEC, and TSST were 0.96 U/L, 1.09 U/L, 1.21 U/L, and 1.18 U/L, respectively. There were no statistically significant differences between the two groups in terms of the qualitative or quantitative results. Serum IgE antibodies to SEA, SEB, SEC, and TSST were detected in 43.7% of the patients in our sample. However, neither the qualitative nor quantitative results showed a statistically significant association with the clinical severity of asthma.

  2. The association between technology type and diffusion pattern under duopolistic competition

    2007-01-01

    Full Text Available Many firms consider adopting new technologies as a means for enhancing competitive advantages. Therefore, the subject of technology diffusion has been studied by many researchers from different disciplines in order to explore the diffusion profiles throughout the industry or the country. The argument has frequently been made that the pattern of diffusion associated with most new technologies will typically have certain characteristics. In general, the diffusion pattern within an industry will depend on the competitive arena and technology characteristics. Based on a duopolistic game-theoretic model, this paper tries to explore the association between technology type and diffusion pattern. The results show that the cost-reducing technologies are adopted sequentially within a duopoly. On the other hard, strategic technologies diffuse over time or in a swarm. Although both technologies might be adopted sequentially, the rate for strategic technologies is faster than that for cost-reducing technologies. .

    This study, based on the investigations carried on 82 cases of Turners of which 50 of them were mosaics and 85 cases of Klinefelters of which 70 of them were mosaics, is an attempt to explain the vast range of clinical variations observed in cytogenetically established Turner mosaics (45,X/46,XX) and Klinefelter mosaics (47,XXY/46,XY) in the light of the degree of mosaicism present in them. It was observed that the severity of the syndrome in Turner mosaics and Klinefelter mosaics increased with the relative increase in the abnormal cell line population.

    The degree of abnormality and rate of change in cognitive functions, positron emission tomography Pittsburg compound B (PET PIB), and fluorodeoxyglucose (FDG) measures were studied for 8 years in an autopsy-confirmed Alzheimer's disease (AD) patient, who died 61 years old (Mini-Mental State Examination (MMSE) score 7). At first encounter with medical care, the patient was very mildly demented (MMSE score 27). She had four cognitive assessments and two examinations with PET PIB and FDG in 23 bilateral brain regions. The onset of cognitive decline was retrospectively estimated to have started in the early forties. The degree of impairment was inversely related to the rate of decline. A similar relationship was seen between the rate of change and the level of abnormality in both PIB and FDG. To conclude, rate of change in cognition, PIB, and FDG was associated with the degree of abnormality.

    Boundary effects are investigated for fluids with internal orientational degrees of freedom such as molecular liquids, thermotropic and lyotropic liquid crystals, and polymeric fluids. The orientational degrees of freedom are described by the second rank alignment tensor which is related to the birefringence. We use a standard model to describe the orientational dynamics in the presence of flow, the momentum balance equations, and a constitutive law for the pressure tensor to describe our system. In the spirit of irreversible thermodynamics, boundary conditions are formulated for the mechanical slip velocity and the flux of the alignment. They are set up such that the entropy production at the wall inferred from the entropy flux is positive definite. Even in the absence of a true mechanical slip, the coupling between orientation and flow leads to flow profiles with an apparent slip. This has consequences for the macroscopically measurable effective velocity. In analytical investigations, we consider the simplified case of an isotropic fluid in the Newtonian and stationary flow regime. For special geometries such as plane and cylindrical Couette flow, plane Poiseuille flow, and a flow down an inclined plane, we demonstrate explicitly how the boundary conditions lead to an apparent slip. Furthermore, we discuss the dependence of the effective viscosity and of the effective slip length on the model parameters.

    Gamma-ray binaries are stellar systems for which the spectral energy distribution (discounting the thermal stellar emission) peaks at high energies. Detected from radio to TeV gamma rays, the {gamma}-ray binary LS I +61 Degree-Sign 303 is highly variable across all frequencies. One aspect of this system's variability is the modulation of its emission with the timescale set by the {approx}26.4960 day orbital period. Here we show that, during the time of our observations, the {gamma}-ray emission of LS I +61 Degree-Sign 303 also presents a sinusoidal variability consistent with the previously known superorbital period of 1667 days. This modulation is more prominently seen at orbital phases around apastron, whereas it does not introduce a visible change close to periastron. It is also found in the appearance and disappearance of variability at the orbital period in the power spectrum of the data. This behavior could be explained by a quasi-cyclical evolution of the equatorial outflow of the Be companion star, whose features influence the conditions for generating gamma rays. These findings open the possibility to use {gamma}-ray observations to study the outflows of massive stars in eccentric binary systems.

    The challenges of providing exemplary undergraduate nursing education cannot be underestimated in an era when burnout and negative mood states predictably lead to alarming rates of academic as well as career attrition. While the multi-dimensional nature of this complex issue has been extensively elucidated, few rational strategies exist to reverse a disheartening trend recognizable early in the educational process that subsequently threatens to undermine the future viability of quality healthcare. This controlled prospective crossover study examined the impact of a 6-session Recreational Music-making (RMM) protocol on burnout and mood dimensions as well as Total Mood Disturbance (TMD) in first year associate level nursing students. A total of 75 first year associate degree nursing students from Allegany College of Maryland (ACM) participated in a 6-session RMM protocol focusing on group support and stress reduction utilizing a specific group drumming protocol. Burnout and mood dimensions were assessed with the Maslach Burnout Inventory and the Profile of Mood States respectively. Statistically significant reductions of multiple burnout and mood dimensions as well as TMD scores were noted. Potential annual cost savings for the typical associate degree nursing program (16,800 dollars) and acute care hospital (322,000 dollars) were projected by an independent economic analysis firm. A cost-effective 6-session RMM protocol reduces burnout and mood dimensions as well as TMD in associate degree nursing students.

  9. Does Degree of Gyrification Underlie the Phenotypic and Genetic Associations between Cortical Surface Area and Cognitive Ability?

    The phenotypic and genetic relationship between global cortical size and general cognitive ability (GCA) appears to be driven by surface area (SA) and not cortical thickness (CT). Gyrification (cortical folding) is an important property of the cortex that helps to increase SA within a finite space, and may also improve connectivity by reducing distance between regions. Hence, gyrification may be what underlies the SA-GCA relationship. In previous phenotypic studies, a 3-dimensional gyrification index (3DGI) has been positively associated with cognitive ability and negatively associated with mild cognitive impairment, Alzheimer’s disease, and psychiatric disorders affecting cognition. However, the differential genetic associations of 3DGI and SA with GCA are still unclear. We examined the heritability of 3DGI, and the phenotypic, genetic, and environmental associations of 3DGI with SA and GCA in a large sample of adult male twins (N = 512). Nearly 85% of the variance in 3DGI was due to genes, and 3DGI had a strong phenotypic and genetic association with SA. Both 3DGI and total SA had positive phenotypic correlations with GCA. However, the SA-GCA correlation remained significant after controlling for 3DGI, but not the other way around. There was also significant genetic covariance between SA and GCA, but not between 3DGI and GCA. Thus, despite the phenotypic and genetic associations between 3DGI and SA, our results do not support the hypothesis that gyrification underlies the association between SA and GCA. PMID:25433211

    Background Nonalcoholic fatty liver disease (NAFLD) is among the most common chronic diseases of the modern world with a wide variety of factors including genetic, environmental and metabolic. The aim of this study was to verify the association between the degrees of hepatic steatosis at the abdominal ultrasound and the values of aminotransferases (aspartate aminotransferase (AST) and alanine transferase (ALT)), gamma glutamyl transpeptidase (GGT) and homeostasis model assessment-insulin resistance (HOMA-IR) index. Methods A prospective, descriptive survey study, using a quantitative analytical examination, was conducted from July 2013 to July 2014. In the statistical analysis, values were expressed as median, first and third quartiles. We used the nonparametric Kruskal-Wallis test to compare the medians between the degrees of steatosis, adopted a statistical significance of 5% (P ≤ 0.05) and used the statistical program SPSS 22.0. Results We diagnosed 233/800 (29.1%) patients with hepatic steatosis on routine ultrasound, and 65.7% were female. Regarding degrees, 119 had grade 1 (51.0%), 94 grade 2 (40.4%) and 20 grade 3 (8.6%). The median age of the patients with grade 1, 2 or 3 did not vary significantly (P > 0.05). The median body mass index (BMI), although clinically important because of its elevation, did not differ significantly (P > 0.05). ALT levels increased as the degree of hepatic steatosis has advanced as well as the levels of AST, GGT and HOMA-IR. AST values showed a greater association with the severity of fatty liver (P = 0.0001) than the ALT (P = 0.001). Conclusions ALT, AST, GGT and HOMA-IR are associated to the degrees of hepatic steatosis on ultrasound and can help in the selection of patients for the liver histological evaluation. PMID:27785306

    Application of organotins in antifouling systems on ship hulls has been globally prohibited by the International Maritime Organization since September 2008. It is, therefore, anticipated that there is a recovery of imposex-affected gastropod populations worldwide. We studied the population dynamics of the rock shell Reishia clavigera in six locations around Hong Kong's coastal waters, covering different degrees of organotin contamination for 25months (2011-2013). Abundance and density of R. clavigera were higher in clean sites, while they tended to grow faster in polluted sites. Over time, we observed recruitments in clean sites while recruitments in polluted sites were limited. The results suggested that the lack of apparent recovery of the local R. clavigera populations was probably due to the prevalence of organotin contamination, especially triphenyltin, in this region. This study, therefore, calls for mitigation and long-term monitoring of organotin contamination in marine environments of Hong Kong and South China.

    2006-03-01

    Rapid changes in health care have underscored the need for reform in health professions education, including nursing education. One of many problems cited in the nursing and other health sciences education literature is overcrowded curricula; therefore, an evaluation of content is necessary. The purpose of this study was to determine whether differences exist in the frequency that physical examination techniques are performed by associate and baccalaureate degree prepared nurses. Participants completed a survey on performance of various physical examination techniques. A Mann-Whitney test showed no differences between the two groups in terms of frequency of techniques performed. A small negative correlation was found between frequency and years of experience with the nutrition assessment category. A comparison of physical examination content covered in baccalaureate and associate degree nursing programs is needed to further understand these findings.

  13. Spatial and temporal association of outbreaks of H5N1 influenza virus infection in wild birds with the 0 degrees C isotherm.

    Full Text Available Wild bird movements and aggregations following spells of cold weather may have resulted in the spread of highly pathogenic avian influenza virus (HPAIV H5N1 in Europe during the winter of 2005-2006. Waterbirds are constrained in winter to areas where bodies of water remain unfrozen in order to feed. On the one hand, waterbirds may choose to winter as close as possible to their breeding grounds in order to conserve energy for subsequent reproduction, and may be displaced by cold fronts. On the other hand, waterbirds may choose to winter in regions where adverse weather conditions are rare, and may be slowed by cold fronts upon their journey back to the breeding grounds, which typically starts before the end of winter. Waterbirds will thus tend to aggregate along cold fronts close to the 0 degrees C isotherm during winter, creating conditions that favour HPAIV H5N1 transmission and spread. We determined that the occurrence of outbreaks of HPAIV H5N1 infection in waterbirds in Europe during the winter of 2005-2006 was associated with temperatures close to 0 degrees C. The analysis suggests a significant spatial and temporal association of outbreaks caused by HPAIV H5N1 in wild birds with maximum surface air temperatures of 0 degrees C-2 degrees C on the day of the outbreaks and the two preceding days. At locations where waterbird census data have been collected since 1990, maximum mallard counts occurred when average and maximum surface air temperatures were 0 degrees C and 3 degrees C, respectively. Overall, the abundance of mallards (Anas platyrhynchos and common pochards (Aythya ferina was highest when surface air temperatures were lower than the mean temperatures of the region investigated. The analysis implies that waterbird movements associated with cold weather, and congregation of waterbirds along the 0 degrees C isotherm likely contributed to the spread and geographical distribution of outbreaks of HPAIV H5N1 infection in wild birds in

    Microhemorrhages on gradient-echo T2*-weighted MRI sequences are often found in patients with cerebrovascular disease and are related to intracerebral hemorrhage. Because statin therapy is associated with increased risk of intracerebral hemorrhage, we investigated whether statin use was also associated with microhemorrhages in patients with acute ischemic stroke or transient ischemic attack. We performed a retrospective analysis on prospectively collected data from a stroke registry containing patients with acute ischemic stroke or transient ischemic attack. The primary and secondary outcome variables were the prevalence and degree of microhemorrhages as detected on gradient-echo MRI sequences and categorized as mild (1-2), moderate (3-10), or severe (>10). The location of the microhemorrhages was noted and rated by 2 neuroradiologists. Previous use of statins and other covariates were assessed as potential predictors. Three hundred forty-nine patients were admitted from June 2008 to July 2009, and 300 of which were analyzed. Microhemorrhages were detected in 70 subjects (23%); 35 had only lobar lesions, 16 had only deep lesions, and 19 had both lobar and deep lesions. On univariate and multivariate analysis, statin therapy was not associated with the prevalence (OR, 0.73; 95% CI, 0.36-1.51; P=0.40) or degree of microhemorrhages modeled for lesser severity (OR, 2.31; 95% CI, 0.61-8.75; P=0.22). Previous statin therapy was not associated with the prevalence or degree of microhemorrhages in patients with acute ischemic stroke or transient ischemic attack. The association between statins and intracerebral hemorrhage does not appear to be mediated through microhemorrhages.

    Full Text Available The present project is part of the course in biochemistry for biomedical undergraduate students of the Federal University of Pernambuco - UFPE, which comprises theoretical and practical classes and interactive seminars prepared by students on studied topics to supplement learning. The aim of this research was to encourage students to innovate their search for knowledge, presenting an interactive strategy to demonstrate the importance of carbohydrates, as well as other energy fuels, for undergraduates students attending classes of biochemistry at the first semester at the university, in order to clarify the importance of maintaining a healthy way of life. The methodology used was a field research, documented in videos in which the opinions of a few people were registered in different places, such as in a fast-food restaurant, on the importance of carbohydrates. Records acquired were associated with a slide presentation on the subject, based on scientific books and articles, which were presented to the students of the discipline. It was also developed a dynamic to illustrate the consumption of carbohydrates in daily life and in different situations. After the project exhibition, a review of the research was conducted to the audience to express innovations or additions to their pre-existing concepts, on consumption of carbohydrates. The results of our work were very promising and the main goal of the project was achieved, since 88.2% of the respondents said there was an improvement in their knowledge, both theoretical and practical, on the subject, while only 11.8% reported no improvement at all. In conclusion, there was a greater involvement of students during the presentation of the subject and a higher participation during the group dynamic on the consumption of carbohydrates.

  1. Quantitative modeling of degree-degree correlation in complex networks

    CERN Document Server

    Niño, Alfonso

    2013-01-01

    This paper presents an approach to the modeling of degree-degree correlation in complex networks. Thus, a simple function, \\Delta(k', k), describing specific degree-to- degree correlations is considered. The function is well suited to graphically depict assortative and disassortative variations within networks. To quantify degree correlation variations, the joint probability distribution between nodes with arbitrary degrees, P(k', k), is used. Introduction of the end-degree probability function as a basic variable allows using group theory to derive mathematical models for P(k', k). In this form, an expression, representing a family of seven models, is constructed with the needed normalization conditions. Applied to \\Delta(k', k), this expression predicts a nonuniform distribution of degree correlation in networks, organized in two assortative and two disassortative zones. This structure is actually observed in a set of four modeled, technological, social, and biological networks. A regression study performed...

    PEGylated PAMAM dendrimers (PEG-PAMAM) have been extensively studied as versatile vehicles for drug delivery. Nevertheless, little information has been reported regarding the effect of the PEGylation degree on the drug-loading properties of these systems, aimed at maximizing their performance as drug carrier nanocarrriers. In this work, fully atomistic molecular dynamics (MD) simulations were employed to examine the association of methotrexate (MTX) with native and diversely PEGylated PAMAM-G4 dendrimers, using 2 kDa PEG chains with substitution degrees from 25 to 100% and 100:1 drug:dendrimer ratios to mimic experimental conditions of drug excess in saturated solution. MD results regarding complex stoichiometries and preferential binding sites were compared to experimental data retrieved from aqueous solubility profiles and 2D-NOESY experiments showing an outstanding level of agreement. The maximum theoretical drug loading capacity was achieved by the system with 34% PEGylation (42:1) through the simultaneous complexation of MTX within internal PAMAM-G4 branches and external PEG chains. On the other hand, higher PEGylation degrees were found to be detrimental for drug complexation due to PEG chains crowding on the dendrimer surface. These results provide valuable information to design more efficient PAMAM-based drug nanocarriers and explain the positive effect that partial PEGylation exerts on the drug-loading capacity of PAMAM-G4 over native and fully PEGylated systems.

    Several studies in patients with schizophrenia reported a marked reduction in sleep spindle activity. To investigate whether the reduction may be linked to genetic risk of the illness, we analysed sleep spindle activity in healthy volunteers, patients with schizophrenia and first-degree relatives, who share an enriched set of schizophrenia susceptibility genes. We further investigated the correlation of spindle activity with cognitive function in first-degree relatives and whether spindle abnormalities affect both fast (12-15 Hz) and slow (9-12 Hz) sleep spindles. We investigated fast and slow sleep spindle activity during non-rapid eye movement sleep in a total of 47 subjects comprising 17 patients with schizophrenia, 13 healthy first-degree relatives and 17 healthy volunteers. Groups were balanced for age, gender, years of education and estimated verbal IQ. A subsample of relatives received additional testing for memory performance. Compared to healthy volunteers, fast spindle density was reduced in patients with schizophrenia and healthy first-degree relatives following a pattern consistent with an assumed genetic load for schizophrenia. The deficit in spindle density was specific to fast spindles and was associated with decreased memory performance. Our findings indicate familial occurrence of this phenotype and thus support the hypothesis that deficient spindle activity relates to genetic liability for schizophrenia. Furthermore, spindle reductions predict impaired cognitive function and are specific to fast spindles. This physiological marker should be further investigated as an intermediate phenotype of schizophrenia. It could also constitute a target for drug development, especially with regard to cognitive dysfunction.

    Full Text Available Background. In hepatitis B virus- (HBV- positive patients, the relationship between the metabolic variables and histological degree of liver fibrosis has been poorly investigated. Methods. A total of 176 HBV-positive patients were assessed in whom the ratios of glycated albumin-to-glycated hemoglobin (GA/HbA1c were calculated in order to investigate the relationship with the degree of liver fibrosis. Results. The GA/HbA1c ratio increased in association with the severity of fibrosis (METAVIR scores: F0-1: 2.61 ± 0.24, F2: 2.65 ± 0.24, F3: 2.74 ± 0.38, and F4: 2.91 ± 0.63. The GA/HbA1c ratios were inversely correlated with four variables of liver function: the prothrombin time (PT percentage (P<0.0001, platelet count (P<0.0001, albumin value (P<0.0001, and cholinesterase value (P<0.0001. The GA/HbA1c ratio was positively correlated with two well-known markers of liver fibrosis, FIB-4 (P<0.0001 and the AST-to-platelet ratio index (APRI (P<0.0001. Furthermore, the GA/HbA1c showed better correlations with two variables of liver function (PT percentage and cholinesterase value than did FIB-4 and with all four variables than did the APRI. Conclusion. The GA/HbA1c ratio is associated with the degree of liver fibrosis in HBV-positive patients.

    Whether a first-degree family history of others cancers (FHOC) than breast or ovarian cancer (BOC) is associated with breast cancer prognosis remains unknown. Thus, the aim of the present study was to clarify this issue. Women who were diagnosed with invasive breast cancer at the Renmin Hospital of Wuhan University from 2010 to 2013 were included in the study. The demographic and clinicopathological characteristics of these patients were extracted. FHOC was considered positive for any patient who had a relative who had been diagnosed with cancer other than BOC. Disease-free survival (DFS) was calculated based on the date of diagnosis. DFS was analyzed using the Cox proportional hazards model. A total of 434 breast cancer patients were included in this study. Among these patients, 61 (14.06%) had a positive FHOC in first-degree relatives. Patients with a positive FHOC tended to have HER2-positive breast cancer (p = 0.03). In the survival analysis, FHOC was associated with poor DFS in both univariate (HR = 2.21 (1.28-3.83), 95% CI: 1.28-3.83, p breast cancer patients with FHOC, especially in patients with luminal A subtype.

    1994-01-01

    This newsletter contains reprinted papers discussing technology options and associated measures for monitoring a Comprehensive Test Ban Treaty (CTBT). These papers were presented to the Conference on Disarmament (CD) in May and June 1994. An interagency Verification Monitoring Task Force developed the papers. The task force included participants from the Arms Control and Disarmament Agency, the Department of Defense, the Department of Energy, the Intelligence Community, the Department of Interior, and the Department of State. The purpose of this edition of Arms Control and Nonproliferation Technologies is to share these papers with the broad base of stakeholders in a CTBT and to facilitate future technology discussions. The papers in the first group discuss possible technology options for monitoring a CTBT in all environments (underground, underwater, atmosphere, and space). These technologies, along with on-site inspections, would facilitate CTBT monitoring by treaty participants. The papers in the second group present possible associated measures, e.g., information exchanges and transparency measures, that would build confidence among states participating in a CTBT.

    Full Text Available Purpose: This study was performed to investigate the incidence of thrombophilic gene mutations in repeated assisted reproductive technology (ART failures. Methods: The prevalence of mutated genes in the patients with a history of three or more previous ART failures was compared with the patients with a history of successful pregnancy following ARTs. The study group included 70 patients, 34 with three or more previously failed ARTs (A and control group consisted of 36 patients with successful pregnancy following ARTs (B. All patients were tested for the presence of mutated thrombophilic genes including factor V Leiden (FVL, Methylenetetrahydrofolate reductase (MTHFR and Prothrombin (G20210A using real-time polymerase chain reaction (RT- PCR. Results: Mutation of FVL gene was detected in 5.9% women of group A (2 of 34 compared with 2.8% women (1 of 36 of control group (P = 0.6. Mutation of MTHFR gene was found in 35.3% (12 cases as compared with 50% (18 cases of control (35.3% versus 50%; P = 0.23. Regarding Prothrombin, only control group had 5.6% mutation (P = 0.49. No significant differences were detected in the incidences of FVL, Prothrombin and MTHFR in the study group A compared with the control group B. Conclusion: The obtained results suggest that thrombophilia does not have a significant effect in ART failures.

    To investigate the relationship between soluble intercellular adhesion molecule (sICAM-1), vascular endothelial cell adhesion molecule (VCAM-1), monocytes chemotactic protein (MCP-1), von Willebrand factor (vWF), and coronary artery stenoses degree in coronary heart disease (CHD) within type 2 diabetes mellitus (T2DM) patients. A total of 92 subjects were treated with coronary angiography (CAG), including 62 subjects with CHD. The individuals were divided into three groups, group A (32 patients with CHD and T2DM), group B (30 patients with CHD but no T2DM) and group C (30 patients with no CHD and T2DM). All patients were treated with a Gensini coronary angiography check. The correlations between sICAM-1, VCAM-1, MCP-1 and vWF in peripheral blood and coronary artery stenosis degree were analyzed. The average score of coronary artery stenosis degree was 30.75 +/-12.67 in group A, which was significantly higher than group B (11.20 +/-7.51) and group C (2.40 +/- 1.23) (p coronary artery stenosis and the mean level of sICAM-1, VCAM-1, MCP-1, vWF in group A (p 0.05). Association analysis shown that the level of sICAM-1, VCAM-1, MCP-1 and vWF elevated in CHD with T2DM patients. Vascular endothelial dysfunction could be caused to the coronary artery stenosis pathophysiological process. Results from this study suggested that sICAM-1, VCAM-1, MCP-1 and vWF may contribute to the occurrence and development of vascular lesions in T2DM. These endothelial function related factors could be acceptable as a prediction and testing index of vascular complications in T2DM.

    to verify whether there are associations among occupational roles, independence to perform Activities of Daily Living, purchasing power, and assistive technology for individuals with physical disabilities. 91 individuals with physical disabilities participated in the study. The instruments used were: Role Checklist, Brazilian Economic Classification Criterion, Barthel Index, and a Questionnaire to characterize the subjects. an association with a greater number of roles was found among more independent individuals using a lower number of technological devices. Higher purchasing power was associated with a lower functional status of dependence. even though technology was not directly associated with independence, the latter was associated with a greater number of occupational roles, which requires reflection upon independence issues when considering the participation in occupational roles. These findings support interdisciplinary actions designed to promote occupational roles in individuals with physical disabilities.

    Comparative studies on the distribution of archaeal versus bacterial communities associated with the surface mucus layer of corals have rarely taken place. It has therefore remained enigmatic whether mucus-associated archaeal and bacterial communities exhibit a similar specificity towards coral hosts and whether they vary in the same fashion over spatial gradients and between reef locations. We used microbial community profiling (terminal-restriction fragment length polymorphism, T-RFLP) and clone library sequencing of the 16S rRNA gene to compare the diversity and community structure of dominant archaeal and bacterial communities associating with the mucus of three common reef-building coral species (Porites astreoides, Siderastrea siderea and Orbicella annularis) over different spatial scales on a Caribbean fringing reef. Sampling locations included three reef sites, three reef patches within each site and two depths. Reference sediment samples and ambient water were also taken for each of the 18 sampling locations resulting in a total of 239 samples. While only 41% of the bacterial operational taxonomic units (OTUs) characterized by T-RFLP were shared between mucus and the ambient water or sediment, for archaeal OTUs this percentage was 2-fold higher (78%). About half of the mucus-associated OTUs (44% and 58% of bacterial and archaeal OTUs, respectively) were shared between the three coral species. Our multivariate statistical analysis (ANOSIM, PERMANOVA and CCA) showed that while the bacterial community composition was determined by habitat (mucus, sediment or seawater), host coral species, location and spatial distance, the archaeal community composition was solely determined by the habitat. This study highlights that mucus-associated archaeal and bacterial communities differ in their degree of community turnover over reefs and in their host-specificity.

    2011-10-01

    The scope of this study was to analyze the factors associated with the degree of participation in physical activities (DPPA) among students of a public university in the south of Brazil. The Canadian Society for Exercise Physiology Questionnaire was used for the evaluation of DPPA. DPPA was classified as adequate and inadequate. Nutritional status was evaluated based on BMI, classified as normal ( 25 kg/m²). The following socio-demographic variables were analyzed: gender, age group, work, maternal educational level, class period, and marital status. Poisson regression was used to examine the association between DPPA and independent variables, considering p < 0.05. The sample, which was representative of the institution, consisted of 738 students (59.2% males). The prevalence of inadequate physical activity participation was 30.8%. Adjusted analysis showed that female (PR=2.79; 95%CI: 2.10-3.68) and overweight students (PR=1.53; 95%CI: 1.04-2.23) presented a higher risk of inadequate physical activity participation. These findings might be useful for the implementation of health promotion programs in universities, which should pay special attention to female and overweight students in their freshman year.

    The role of colonic mucosal ornithine decarboxylase (ODC) in inflammatory bowel disease (IBD) remains controversial. This study assessed mucosal ODC activity in IBD patients segment by segment with regard to patient characteristics, disease activity/duration, medication, degree of mucosal inflammation, and presence/absence of epithelial regeneration and guanosine triphosphate (GTP) stimulation. Mucosal ODC activity was determined in biopsy specimens from the terminal ileum, cecum/ascending, transverse, and descending colon, and the sigmoid/rectum of 35 patients with IBD (18 with Crohn's disease, 17 with ulcerative colitis) and 29 controls, using the amount of 14CO2 liberated from (carboxyl-14C)ornithine hydrochloride. GTP-stimulatable activity was expressed as the ratio of ODC activity in the presence and absence of GTP (70 micromol/L). Mucosal inflammation was assessed endoscopically/microscopically with previously described criteria. Presence/absence of mucosal regeneration also was determined by predefined criteria. Mucosal ODC-activity did not significantly differ in IBD patients and controls. There was a 4.4-fold activity gradient from the ileum to the rectum. Mucosal ODC activity was significantly higher in areas with epithelial regeneration compared to those without regeneration, and was stimulated by GTP by a factor of 1.42 in Crohn's disease and 1.19 in ulcerative colitis patients compared to controls (p < 0.004). On the other hand, there was no significant association/relationship of mucosal ODC activity with disease activity/duration and the endoscopic/histologic degree of mucosal inflammation. The observation of unchanged mucosal ODC activity in patients with IBD and the absence of a significant relationship with clinical and endoscopic/histologic disease characteristics speaks against a major role of ODC in IBD as a major disease marker. The role of the ileorectal gradient, the enhanced activity in areas with epithelial regeneration, and the GTP

    Full Text Available Carbonization of Radix Rehmanniae Preparata (Shu Dihuangtan via stir-frying could increase its homeostasis maintaining and antidiarrheal effects. To ensure these pharmacological functions, the quality of the raw material (processed Rehmanniae Radix must be well controlled. Therefore, we analyzed the effects of different degrees of processing and adjuvants on processed Rehmanniae Radix (Shu Dihuang by High Performance Liquid Chromatography (HPLC chromatographic fingerprints, thermal gravimetric analysis and Fourier transform infrared spectroscopy (FTIR. Based on the results from HPLC fingerprints combined with similarity analysis (SA and hierarchical cluster analysis (HCA the optimum processing method for Shu Dihuang was five cycles of steaming and polishing, which follows the ancient processing theory. The intensity of thermal weight loss rate peaked near 210.33 ± 4.32 °C or 211.33 ± 2.62 °C, which was an important indicator for the degree of processing of Shu Dihuang. A temperature near 290.89 ± 2.51 °C was the upper limit for carbonizing Shu Dihuangtan. FTIR spectroscopy analysis showed that the overall chemical composition of Shu Dihuangtan was affected by both the degree of processing and adjuvant, which are very important for its quality.

    Full Text Available BackgroundFamily history of type 2 diabetes mellitus (T2DM is one of risk factors for that in future a subject can develop diabetes. Insulin resistance (IR is important in the pathogenesis of T2DM. There is evidence that oxidative stress plays an important role in the etiology and/or progression of diabetes. Myeloperoxidase (MPO participates in developing of inflammation. The objective was to investigate if MPO is associated with IR and inflammation in individuals with first-degree relatives of T2DM.MethodsCross-sectional study in 84 overweight individuals with family history of T2DM divided in two groups according to IR, group with IR (homeostasis model assessment [HOMA] ≥2.5; n=43 and control group (CG; HOMA <2.5; n=41. Complete clinical history and a venous blood sample were collected for measuring glucose and lipids profile, insulin, interleukin-6 (IL-6, tumor necrosis factor-α (TNF-α, MPO, glutathione reductase (GRd, glutathione peroxidase, and superoxide dismutase.ResultsMPO, TNF-α, and IL-6 were higher in patients with IR than in CG (MPO: 308.35 [190.85 to 445.42] vs. 177.35 [104.50 to 279.85], P=0.0001; TNF-α: 13.46 [10.58 to 18.88] vs. 9.39 [7.53 to 11.25], P=0.0001; IL-6: 32.93 [24.93 to 38.27] vs. 15.60 [12.93 to 26.27]; P=0.0001, respectively. MPO was associated with IR (rho de Spearman=0.362, P=0.001. In the analysis of lineal regression, MPO predicts IR (β, 0.263; t, 2.520; P=0.014. In the univariate analysis, MPO had an odds ratio of 9.880 for risk of IR (95% confidence interval, 2.647 to 36.879.ConclusionMPO had relation with IR and inflammation parameters in overweight subjects with first-degree relatives of T2DM. We need studies on a casual relationship and molecular mechanisms among the increased serum MPO levels, inflammation markers, and IR.

    Cotton fiber fineness and maturity measured indirectly as micronaire (MIC) are important properties of determining fiber grades in the textile market. To understand the genetic control and molecular mechanisms of fiber fineness and maturity, we studied two near isogenic lines, Gossypium hirsutum, Texas Marker-1 wild type (TM-1) and immature fiber (im) mutant showing a significant difference in MIC values. The fibers from im mutant plants were finer and less mature with lower MIC values than those from the recurrent parent, TM-1. A comprehensive fiber property analysis of TM-1 and im mutant showed that the lower MIC of fibers in im mutant was due to the lower degree of fiber cell wall thickening as compared to the TM-1 fibers. Using an F(2) population comprising 366 progenies derived from a cross between TM-1 and im mutant, we confirmed that the immature fiber phenotype present in a mutant plant was controlled by one single recessive gene im. Furthermore, we identified 13 simple sequence repeat markers that were closely linked to the im gene located on chromosome 3. Molecular markers associated with the im gene will lay the foundation to further investigate genetic information required for improving cotton fiber fineness and maturity.

    Full Text Available A new materials model for sand has been developed in order to include the effects of the degree of saturation and the deformation rate on the constitutive response of this material. The model is an extension of the original compaction materials model for sand in which these effects were neglected. The new materials model for sand is next used, within a non-linear-dynamics transient computational analysis, to study various phenomena associated with the explosion of shallow-buried and ground-laid mines. The computational results are compared with the corresponding experimental results obtained through the use of an instrumented horizontal mine-impulse pendulum, pressure transducers buried in sand and a post-detonation metrological study of the sand craters. The results obtained suggest that the modified compaction model for sand captures the essential features of the dynamic behavior of sand and accounts reasonably well for a variety of the experimental findings related to the detonation of shallow-buried or ground-laid mines.

    Full Text Available Background: To evaluate if hormonal profile of children with isolated hypospadias (IH associates better with comprehensive local anatomical factor score (LAFS than with clinically adjudged urethral meatus location or severity of chordee/k.j. Material and Methods: Ninety-nine children with IH were enrolled, as per inclusion criteria. Meatal location was recorded at first clinical examination in OPD; while LAFS was computed per-operatively using indigenously devised scale, except for neonates. Hypospadiacs were first classified into three standard meatal based groups and subsequently into LAFS based two groups (≤19, >19. For all participants, pre HCG and post HCG (96 hour post- injection estimation of serum gonadotropins, DHEA-S, estrogen (E, progesterone (P, testosterone (T and Dihydrotestosterone (DHT was done. Statistical tests were applied to assess significance of hormonal levels with respect to meatal location, chordee and LAFS. Results: Only FSH levels differed significantly among meatal based groups; while among LAFS groups, multiple hormonal differences were noted; with poor LAFS associated significantly with higher FSH, LH and lower E, T/DHT. Children with severe degree of chordee had poorer T output and a significantly lower LAFS as compared to those with moderate/mild chordee. Conclusion: Serotoli cell dysfunction, indirectly indicated by high FSH was found among midpenile hypospadiacs and those with poorer LAFS. Since groups based on LAFS revealed multiple intergroup hormonal differences than what was seen for meatal/chordee based groups; LAFS should be considered a better guide for prognostication and for deciding about hormonal supplementation. Lower androgenic output was particularly noted in children with severe chordee.

    We tested the hypothesis that weekday bedtime use of six technologies would be significantly associated with eight sleep parameters studied relating to sleep quantity, sleep quality, and parasomnias. In our cross-sectional study, we previously administered validated age-appropriate questionnaires (School Sleep Habits Survey, Technology Use Questionnaire). Participating adolescents (n=738; 54.5% boys) were aged 11-13 years and were from the Midlands region of the United Kingdom in 2010. Frequent use of all technology types was significantly inversely associated with weekday sleep duration (hours). Frequent music listeners and video gamers had significantly prolonged sleep onset (β=7.03 [standard error {SE}, 2.66]; Ptechnology types. The greatest effect was observed in frequent television viewers (odds ratio [OR], 4.05 [95% confidence interval {CI}, 2.06-7.98]). Difficulty falling asleep was significantly associated with frequent mobile telephone use, video gaming, and social networking, with music listeners demonstrating the greatest effect (OR, 2.85 [95%CI, 1.58-5.13]). Music listeners were at increased risk for frequent nightmares (OR, 2.02 [95% CI, 1.22-3.45]). Frequent use of all technologies except for music and mobile telephones was significantly associated with greater cognitive difficulty in shutting off. Frequent television viewers were almost four times more likely to report higher sleepwalking frequency (OR, 3.70 [95% CI, 1.89-7.27]). Frequent weekday technology use at bedtime was associated with significant adverse effects on multiple sleep parameters. If confirmed in other samples and longitudinally, improving sleep hygiene through better management of technology could enhance the health and well-being of adolescent populations.

    This paper reports on an exploratory study among adolescents (N = 752) who were introduced to the emerging technology of ecogenomics for the first time. An online survey focused on their associations with the term ecogenomics, their planned information seeking behaviors if they were to acquire information about the new technology, and their first affective responses toward ecogenomics after having read some introductory information about it. Adolescents were found to associate ecogenomics most frequently with economy. Although the Internet was the most popular medium to be used in their planned information seeking behaviors, books and science communication professionals were judged as the most trustworthy information sources. After having read the introductory information about ecogenomics most adolescents reported positive affective responses toward the new technology.

    Food processing impacts both food structure and nutritional density. The effect of food structure on satiety and glycemic potentials is well recognized. However, the association between processing, satiety and glycemic potentials and nutrient profiles has not been much studied, especially in the diets of the elderly. Therefore, this study aimed at exploring relations between the level of food processing, consumption and nutrient profiles and satiety and glycemic potentials among 6686 French elderly people (≥65 years). Dietary assessment was realized through a web-based 24 h dietary record tool. Among a total of 2688 foods, 280 generic foods were aggregated based on a consumption threshold of at least 5% by the population. The satiety potential was calculated using the Fullness Factor equation, and the glycemic potential using the glycemic index and the glucose glycemic equivalent. Foods and dishes were ranked according to an adapted international NOVA classification as raw/minimally-processed (G1), processed (G2) and ultra-processed (G3). ANOVA and correlation analyses showed that the more food is processed, the lower its satiety potential and nutrient density and the higher its glycemic impact, especially when comparing G1 and G3. Besides, the foods consumed in the greatest quantity daily tend to be the most satiating, and ultra-processed foods were among the less frequently consumed both in terms of percentage and daily quantity (around two-fold difference between minimally- and ultra-processed foods). In conclusion, because it is partly related to health food potential, the degree of processing, especially for ultra-processed products, should be taken into consideration more when evaluating consumption profiles of different populations.

    To estimate the risk of congenital heart defects (CHD) associated with assisted reproductive technologies (ART). We used data from the Paris Registry of Congenital Malformations on 5493 cases of CHD and 3847 malformed controls for which no associations with ART were reported in the literature. Assisted reproductive technologies included inductors of ovulation only, in vitro fertilization, and intracytoplasmic sperm injection. Exposure to ART was higher for cases than controls (4.7 vs. 3.6%, P= 0.008) and was associated with a 40% increase in the maternal age, socioeconomic factors, and year of birth-adjusted odds of CHD without chromosomal abnormalities [adjusted odds ratio (OR) 1.4, 95% confidence interval (CI) 1.1-1.7]. Assisted reproductive technologies were specifically associated with significant increases in the odds of malformations of the outflow tracts and ventriculoarterial connections (adjusted OR 1.7, 95% CI 1.2-2.4) and of cardiac neural crest defects and double outlet right ventricle (adjusted OR 1.7, 95% CI 1.1-2.7). In general, we found specific associations between methods of ART and subcategories of CHD. Cases with CHD were more likely to have been conceived following ART when compared with malformed controls. This higher risk for CHD varied specifically according to the method of ART and the type of CHD and may be due to ART per se and/or the underlying infertility of couples.

    Digital technology (DT) plays an increasingly important role in the health sector. This study explores how national public health associations (PHAs) use DT to achieve their mandate. The World Federation of Public Health Associations canvassed and conducted a semi-structured interview with its national public health association members about their use of DT, the challenges they encounter in using it, and their experiences and thoughts as to how to assess its impact, both organizationally as well as on population health and health equity. The study found that digital technology plays an important role in some PHAs, principally those in higher income countries. PHAs want to broaden their use within PHAs and to assess how DT enables PHAs to achieve their organizational mandates and goals, including improved public health and health equity.

    Determination of the effect of microorganisms on spoilage of meat products during various temperature regimes of storage by integral indexes of luminescent lines in their spectra and development of an algorithm of microorganism indication by an express method using laser Raman-luminescent spectroscopy. Minced meat from beef and pork was used. Determination of quantity of mesophilic aerobic and opportunistic-anaerobic microorganisms was carried out by serial 10-fold dilutions with subsequent parallel seeding into Rida count total 24 plates and Petri dishes with 5% blood agar. Sample study was carried out in luminescent software-hardware complex Enspectr L405 (a variant of Enspectr M software-hardware complexes). Meat spoilage was established to be caused to a large degree by Pseudomonas genus (P. fluorescens, P. putida, P. fragi et al.) bacterial growth. Raman-luminescent spectra of bacteria that compose microflora, characterizing and accompanying beef and pork spoilage, were measured and recorded into a database. The results obtained will allow to use this technique in the future for both express-indication and differentiation of microorganisms and express-evaluation of quality of meat products at all stages of their manufacturing, storage, transport and realization.

    Biologists can equip animals with global positioning system (GPS) technology to obtain accurate (less than or equal to 30 m) locations that can be combined with sensor data to study animal behaviour and ecology. We provide the background of GPS techniques that have been used to gather data for wildlife studies. We review how GPS has been integrated into functional systems with data storage, data transfer, power supplies, packaging and sensor technologies to collect temperature, activity, proximity and mortality data from terrestrial species and birds. GPS 'rapid fixing' technologies combined with sensors provide location, dive frequency and duration profiles, and underwater acoustic information for the study of marine species. We examine how these rapid fixing technologies may be applied to terrestrial and avian applications. We discuss positional data quality and the capability for high-frequency sampling associated with GPS locations. We present alternatives for storing and retrieving data by using dataloggers (biologging), radio-frequency download systems (e.g. very high frequency, spread spectrum), integration of GPS with other satellite systems (e.g. Argos, Globalstar) and potential new data recovery technologies (e.g. network nodes). GPS is one component among many rapidly evolving technologies. Therefore, we recommend that users and suppliers interact to ensure the availability of appropriate equipment to meet animal research objectives.

    Full Text Available The aim of this study is to determine senior student teachers’ perceptions on using technology by approaching various points of view. In this study, researchers collected data through Technology Perceptions Scale, Visual Association Activity and Technology Metaphors. The participants of the study were 104 senior student teachers who were enrolled in Balıkesir University Necatibey Faculty of Education. In this descriptive study, researchers interpreted qualitative data in conjunction with quantitative data. Based on the data obtained, even though student teachers’ perceptions on using technology were found positive in the light of Likert scale, there was no significant relation in terms of gender and enrolled undergraduate program. According to the results of visual association test, student teachers ranked smartboard, Internet and computer in the first three, and portable media player, mobile phone and video/camera in the last three. Besides, researchers analyzed and classified student teachers’ metaphors about technology under 9 categories: 1developing-changing technology, 2rapidly progressing technology, 3 limitless-endless technology, 4beneficial technology, 5harmful technology, 6both beneficial and harmful technology, 7indispensible technology, 8technology as a necessity, 9 all-inclusive technology. At the end of the study, those nine categories which were acquired using the content analysis technique are presented in a table which shows the interaction between categories in a holistic view.

    Information technology (IT) adoption enables biomedical research. Publications are an accepted measure of research output, and network models can describe the collaborative nature of publication. In particular, ecological networks can serve as analogies for publication and technology adoption. We constructed network models of adoption of bioinformatics programming languages and health IT (HIT) from the literature.We selected seven programming languages and four types of HIT. We performed PubMed searches to identify publications since 2001. We calculated summary statistics and analyzed spatiotemporal relationships. Then, we assessed ecological models of specialization, cooperativity, competition, evolution, biodiversity, and stability associated with publications.Adoption of HIT has been variable, while scripting languages have experienced rapid adoption. Hospital systems had the largest HIT research corpus, while Perl had the largest language corpus. Scripting languages represented the largest connected network components. The relationship between edges and nodes was linear, though Bioconductor had more edges than expected and Perl had fewer. Spatiotemporal relationships were weak. Most languages shared a bioinformatics specialization and appeared mutualistic or competitive. HIT specializations varied. Specialization was highest for Bioconductor and radiology systems. Specialization and cooperativity were positively correlated among languages but negatively correlated among HIT. Rates of language evolution were similar. Biodiversity among languages grew in the first half of the decade and stabilized, while diversity among HIT was variable but flat. Compared with publications in 2001, correlation with publications one year later was positive while correlation after ten years was weak and negative.Adoption of new technologies can be unpredictable. Spatiotemporal relationships facilitate adoption but are not sufficient. As with ecosystems, dense, mutualistic

    Prospective studies are based on the analysis of patent documents and aims to assess the both technological history and development providing innovation opportunities. This study was a technological prospection mapping aiming to identify breakthrough in PDT and the new possibilities of the technology. Therefore, research in the bank patent 'Spacenet Patent Search' was performed using determinants descriptors associated with the theme: 'A61K41', 'A61N5 / 06'. Were analyzed in this study 326 documents. In evaluating these patents, it was possible to observe an increase in the number of deposits over time, with peak between 1990 and 2000. The highest number of inventors of this area are part of the private sector and the US appear as main producer of technology. It was also observed that blue light, porphyrins and their derivatives are the main topics. It may be concluded that PDT still offers a large opportunity for growth as several wavelengths, and photosensitizers that may be used in the technique.

    The development of the information society has led to increased use of everyday technology and changed the conditions for participation. Enabling participation in everyday life situations is an important rehabilitation goal after acquired brain injury (ABI). Identifying factors associated with individuals' experienced participation and problems therein is therefore essential. This study aimed at exploring the relationship between perceived difficulty in everyday technology use, perceived ability in the activities of daily living (ADL), and perceived participation, and participation problems in persons with ABI. Eighty-one persons with ABI participated in the study and were assessed by the Impact on Participation and Autonomy questionnaire, the Everyday Technology Use Questionnaire, and the ADL taxonomy. Findings showed that the combined model of difficulty in everyday technology (ET) use, ADL ability, and the interaction between them explained both participation in various domains of everyday life, and also overall level of perceived participation and the perceived problems. The findings underscore the importance of evaluating individuals' ability in both ET use and ADL after ABI to increase the probability of explaining these persons' participation in desired everyday life situations and, also, for rehabilitation design.

    Nursing informatics/health information technology are key components of graduate nursing education and an accreditation requirement, yet little is known about the extent to which doctor of nursing practice (DNP) curricula include these content domains. The purpose of this descriptive study was to elicit perceptions of DNP program directors relative to (a) whether and how the American Association of Colleges of Nursing's (AACN's) Essential IV standard has been met in their DNP programs; (b) whether the Technology Informatics Guiding Educational Reform Initiative Foundation's Phase II competencies have been integrated in their programs; and (c) the faculty and organizational characteristics associated with the adoption of the AACN's Essential IV. In 2011, an electronic survey was sent to all 138 DNP program directors identified on the AACN Web site with an 81.2% response rate. Findings include variation in whether and how programs have integrated informatics/health information technology content, a lack of informatics-certified and/or master's-prepared faculty, and a perceived lack of faculty awareness of informatics curricular guidelines. DNP program director and dean awareness and support of faculty informatics education, use of informatics competency guidelines, and national policy and stimulus funding support are recommended to promote curricular inclusion and the engagement of nurses in strong informatics practices.

    Individuals with knee osteoarthritis (OA) generally demonstrate great difficulty in ascending stairs. The strategies and compensations used by these individuals in stair activities have not been fully established. The purpose of this study was to investigate the joint kinematics of the pelvis, hip, knee and ankle throughout the gait cycle, in the sagittal and frontal planes, in individuals with mild and moderate knee OA, during an ascending stairs task. Thirty-one individuals with knee OA and 19 controls were subjected to clinical and radiographic analysis, divided into three groups: control, mild knee OA, and moderate knee OA. Participants answered a self-reported questionnaire, carried out performance-based tests, and their kinematic data were recorded during an ascending stairs task using an eight-camera Qualisys 3D-Motion analysis system. The individuals with moderate degrees of knee OA demonstrated kinematic alterations in the pelvis, hip, knee, and ankle in the sagittal plane. The individuals with mild degrees of knee OA demonstrated kinematic alterations of the hip in the frontal plane, and kinematic alterations of the ankle in the sagittal plane. The ascending stairs task allowed verification of meaningful information regarding gait strategies used by individuals with mild and moderate knee OA. The strategies of these two groups of individuals are different for this task, although more pronounced in individuals with moderate knee OA. The findings should be taken into account in the development of rehabilitation programs. Copyright © 2017 Elsevier B.V. All rights reserved.

    The Health Information Technology for Economic and Clinical Health Act (HITECH) allocated $19.2 billion to incentivize adoption of the electronic health record (EHR). Since 2009, Meaningful Use Criteria have dominated information technology (IT) strategy. Health care organizations have struggled to meet expectations and avoid penalties to reimbursements from the Center for Medicare and Medicaid Services (CMS). Organizational theories attempt to explain factors that influence organizational change, and many theories address changes in organizational strategy. However, due to the complexities of the health care industry, existing organizational theories fall short of demonstrating association with significant health care IT implementations. There is no organizational theory for health care that identifies, groups, and analyzes both internal and external factors of influence for large health care IT implementations like adoption of the EHR. The purpose of this systematic review is to identify a full-spectrum of both internal organizational and external environmental factors associated with the adoption of health information technology (HIT), specifically the EHR. The result is a conceptual model that is commensurate with the complexity of with the health care sector. We performed a systematic literature search in PubMed (restricted to English), EBSCO Host, and Google Scholar for both empirical studies and theory-based writing from 1993-2013 that demonstrated association between influential factors and three modes of HIT: EHR, electronic medical record (EMR), and computerized provider order entry (CPOE). We also looked at published books on organizational theories. We made notes and noted trends on adoption factors. These factors were grouped as adoption factors associated with various versions of EHR adoption. The resulting conceptual model summarizes the diversity of independent variables (IVs) and dependent variables (DVs) used in articles, editorials, books, as

    To evaluate and compare the social cognition in patients with schizophrenia, healthy first-degree relatives and controls, by studying the relationship between social cognition and nonsocial cognition, psychopathology, and other clinical and sociodemographic variables. The total sample was comprised of patients diagnosed with paranoid schizophrenia (N = 29), healthy first-degree relatives (N = 21) and controls (N = 28). All groups were assessed with an ad hoc questionnaire and a Social Cognition Scale, which assessed the domains: emotional processing, social perception and attributional style in a Spanish population. The patient group was also assessed with the Scale for the Positive and Negative Syndrome Scale and the Mini-mental state examination. Statistical analyses were performed with SPSS version 15.0. Patients scored significantly worse in all domains of social cognition assessed, compared with controls, and mastery attributional style, compared with relatives. The type of psychopathology correlated negatively and statistically significantly with different domains of social cognition: negative symptoms with emotional processing and attributional style, and positive symptoms with social perception. Basic cognition scores correlated positively and statistically significantly with the domains social perception and attributional style. Social cognition has become an interesting object of study, especially in how it relates to non-social cognition, psychopathology and global functioning of patients, bringing new elements to be considered in the early detection, comprehensive treatment and psychosocial rehabilitation of patients. Its conceptualization as trait variable, the consideration of the existence of a continuum between patients and relatives are plausible hypotheses that require further research.

    Antifibrillar collagen type II (anti-CII) antibody-positive patients with rheumatoid arthritis (RA) have early but not late signs of increased inflammation and joint erosions. We wanted to replicate this in a large RA cohort, and to relate to human leukocyte antigen (HLA)-DRB1* alleles. Anti-CII and anti-cyclic citrullinated peptide (CCP)2 were measured at baseline in 773 patients with RA from the Swedish Epidemiological Investigation in Rheumatoid Arthritis (EIRA) study with clinical follow-up data from the Swedish Rheumatology Quality Register (SRQ) registry, and 1476 with HLA-DRB1* information. Comparisons were done concerning C reactive protein (CRP), erythrocyte sedimentation rate (ESR), tender joint count (TJC), swollen joint count (SJC), Disease Activity Score encompassing 28 joints based on ESR (DAS28), DAS28CRP, pain-Visual Analogue Scale (VAS), global-VAS and Health Assessment Questionnaire Score (HAQ) at eight occasions during 5 years, and association with HLA-DRB1* alleles. Anti-CII associated with elevated CRP, ESR, SJC, DAS28 and DAS28CRP at diagnosis and up to 6 months, whereas anti-CCP2 associated with SJC and DAS28 from 6 months to 5 years, but not earlier. The anti-CII-associated phenotype was strong, and predominated in anti-CII/anti-CCP2 double-positive patients. Anti-CII was associated with improvements in CRP, ESR, SJC, TJC and DAS28, whereas anti-CCP2 was associated with deteriorations in SJC and DAS28 over time. Anti-CII-positive patients achieved European League Against Rheumatism good or moderate response more often than negative patients. Anti-CII was positively associated with HLA-DRB1*01 and HLA-DRB1*03, with significant interaction, and double-positive individuals had >14 times higher mean anti-CII levels than HLA double negatives. Whereas smoking was associated with elevated anti-CCP2 levels, smokers had lower anti-CII levels. Anti-CII seropositive RA represents a distinct phenotype, in many respects representing the converse

  12. A lower degree of PBMC L1 methylation in women with lower folate status may explain the MTHFR C677T polymorphism associated higher risk of CIN in the US post folic acid fortification era.

    Full Text Available Studies in populations unexposed to folic acid (FA fortification have demonstrated that MTHFR C677T polymorphism is associated with increased risk of higher grades of cervical intraepithelial neoplasia (CIN 2+. However, it is unknown whether exposure to higher folate as a result of the FA fortification program has altered the association between MTHFR C677T and risk of CIN, or the mechanisms involved with such alterations. The current study investigated the following in a FA fortified population: 1 The association between MTHFR C677T polymorphism and risk of CIN 2+; 2 The modifying effects of plasma folate concentrations on this association; and 3 The modifying effects of plasma folate on the association between the polymorphism and degree of methylation of long interspersed nucleotide elements (L1s, in peripheral blood mononuclear cell (PBMC DNA, a documented biomarker of CIN risk.The study included 457 US women diagnosed with either CIN 2+ (cases or ≤ CIN 1 (non-cases. Unconditional logistic regression models were used to test the associations after adjusting for relevant risk factors for CIN.The 677CT/TT MTHFR genotypes were not associated with the risk of CIN 2+. Women with CT/TT genotype with lower folate, however, were more likely to be diagnosed with CIN 2+ compared to women with CT/TT genotype with higher folate (OR = 2.41, P = 0.030. Women with CT/TT genotype with lower folate were less likely to have a higher degree of PBMC L1 methylation compared to women with CT/TT genotype with higher folate (OR = 0.28, P = 0.017.This study provides the first evidence that the MTHFR 677CT/TT genotype-associated lower degree of PBMC L1 methylation increases the risk of CIN 2+ in women in the US post-FA fortification era. Thus, even in the post-FA fortification era, not all women have adequate folate status to overcome MTHFR 677CT/TT genotype-associated lower degree of L1 methylation.

    The increasing temperature in Arctic tundra deepens the active layer, which is the upper layer of permafrost soil that experiences repeated thawing and freezing. The increasing of soil temperature and the deepening of active layer seem to affect soil microbial communities. Therefore, information on soil microbial communities at various soil depths is essential to understand their potential responses to climate change in the active layer soil. We investigated the community structure of soil bacteria in the active layer from moist acidic tundra in Council, Alaska. We also interpreted their relationship with some relevant soil physicochemical characteristics along soil depth with a fine scale (5 cm depth interval). The bacterial community structure was found to change along soil depth. The relative abundances of Acidobacteria, Gammaproteobacteria, Planctomycetes, and candidate phylum WPS-2 rapidly decreased with soil depth, while those of Bacteroidetes, Chloroflexi, Gemmatimonadetes, and candidate AD3 rapidly increased. A structural shift was also found in the soil bacterial communities around 20 cm depth, where two organic (upper Oi and lower Oa) horizons are subdivided. The quality and the decomposition degree of organic matter might have influenced the bacterial community structure. Besides the organic matter quality, the vertical distribution of bacterial communities was also found to be related to soil pH and total phosphorus content. This study showed the vertical change of bacterial community in the active layer with a fine scale resolution and the possible influence of the quality of soil organic matter on shaping bacterial community structure.

    Numerous studies have examined relationships between disease biomarkers (such as blood lipids) and levels of circulating or cellular fatty acids. In such association studies, fatty acids have typically been expressed as the percentage of a particular fatty acid relative to the total fatty acids in a sample. Using two human cohorts, this study examined relationships between blood lipids (TAG, and LDL, HDL or total cholesterol) and circulating fatty acids expressed either as a percentage of total or as concentration in serum. The direction of the correlation between stearic acid, linoleic acid, dihomo-γ-linolenic acid, arachidonic acid and DHA and circulating TAG reversed when fatty acids were expressed as concentrations v. a percentage of total. Similar reversals were observed for these fatty acids when examining their associations with the ratio of total cholesterol:HDL-cholesterol. This reversal pattern was replicated in serum samples from both human cohorts. The correlations between blood lipids and fatty acids expressed as a percentage of total could be mathematically modelled from the concentration data. These data reveal that the different methods of expressing fatty acids lead to dissimilar correlations between blood lipids and certain fatty acids. This study raises important questions about how such reversals in association patterns impact the interpretation of numerous association studies evaluating fatty acids and their relationships with disease biomarkers or risk.

    In this exploratory research, we use panel data analysis to examine the correlation between Information and Communication Technology (ICTs) and public health delivery at the country level. The goal of this exploratory research is to examine the strategic association over time between ICTs and country-level public health. Using data from the World Development Indicators, we construct a panel data set of countries of five different income levels and look closely at the period from 2000 to 2008. The panel data analysis allows us to explore this dynamic relationship under the control for unobserved country-specific effects by using a fixed-effects estimation method. In particular,, we examine the association of five ICT factors with five public health indicators: adolescent fertility rate, child immunization coverage, tuberculosis case detected, life expectancy, and adult mortality rate. First, overall ICTs' factors substantially improve a country's public health delivery on the top of wealth effect. Second, among all the ICTs' factors, accessibility is the only one that is associated with improvements in all aspects of public health delivery, while the contributions from the usage, quality, and applications are negligible. ICTs' accessibility factor is associated with a considerable extension to life expectancy and reduced adult mortality rate. Third, all entity-specific factors are significant in each model, indicating that countries' economic development level does influence their public health delivery. Our results indicate that ICT accessibility has a strong association with effective delivery of public health. There are others, but the key strategic applications are eHealth and mHealth. The findings of this study will help government officials and public health policy makers to formulate strategic decisions regarding the best ICT investments and deployment. For example, the study shows that providing accessibility should be a critical focus.

    Microplitis croceipes and Cotesia marginiventris (Hymenoptera: Braconidae) are parasitoids of lepidopteran larvae with different degrees of host specificity. Both parasitoid species rely on host-related plant volatiles as odor cues to locate their herbivore hosts. To better understand mechanisms of odor processing in parasitoids, we tested responses of olfactory sensory neurons (OSNs) in the antennal sensilla placodea of female parasitoids to select plant volatiles and mixtures. The compounds tested include two green leaf volatiles (i.e., cis-3-hexenol and hexanal) and three herbivore-induced plant volatiles (i.e., cis-3-hexenyl butyrate, cis-3-hexenyl acetate and linalool). Single-sensillum recording showed that the test compounds elicited activity in large and small amplitude neurons housed in the short sensilla placodea of both parasitoid species. In general, C. marginiventris showed greater OSN responses to a low dose while M. croceipes showed greater responses to a high dose of test compounds. Binary mixtures of cis-3-hexenol and linalool inhibited OSN activity in M. croceipes, but not in C. marginiventris. These differences may have implications for odor discrimination in the two parasitoid species. In addition, anterograde neurobiotin stainings were performed to map glomerular projections of OSNs in the antennal lobe of the parasitoids. In M. croceipes, a mixture of cis-3-hexenol and linalool inhibited activity of the glomerulus activated by cis-3-hexenol alone. In C. marginiventris, a mixture of cis-3-hexenol and cis-3-hexenyl acetate showed intense labeling in their respective glomeruli, possibly suggesting a synergistic interaction. These differences in detection and coding of single compounds and mixtures may impact host location strategies in the two parasitoid species. Copyright © 2017 Elsevier Ltd. All rights reserved.

    There are limited data on the clinical significance of left ventricular (LV) mass and late gadolinium enhancement (LGE) in pediatric hypertrophic cardiomyopathy (HC). We reviewed cardiovascular magnetic resonance (CMR) studies of children with HC to investigate the associations between the extent and distribution of LGE and LV mass with ventricular tachycardia (VT) in children with HC. A blinded observer reviewed CMR studies for the presence and distribution of LV hypertrophy and LGE using a 17-segment model. The primary outcome was VT. LGE was present 17 of 33 subjects (52%). VT was present on outpatient Holter monitor or exercise stress test in 7 patients, of which 5 patients (71%) had LGE. Each additional segment of LGE was associated with an increase in the odds of VT (odds ratio [OR] 1.4, 95% CI 1.1 to 1.9) and fewer than 5 segments with LGE had 93% specificity for the presence or absence of VT (OR 0.06, 95% CI 0.01 to 0.5). VT was more common in patients with LGE in the apical septal (p = 0.03), basal inferoseptal (p <0.01), and basal inferior (p = 0.04) segments, whereas LGE in more commonly involved segments (midanteroseptal and midinferoseptal) was not associated with VT (p = 0.13, 0.26). Patients with VT had greater LV mass index (76.4 ± 40.4 g/m(2.7) vs 50.9 ± 24.3 g/m(2.7); p = 0.03). Each centimeter of increased maximum LV thickness was associated with increased likelihood of VT (OR 2.9, 95% CI 1.2 to 6.8). In conclusion, in pediatric HC, CMR to evaluate the extent and pattern of LGE, LV mass index, and maximum LV thickness may help to identify children with HC at risk of VT.

    The increased interest in healthcare-associated infection (HCAI) among the public, patients and politicians has led to the development of potential new approaches to its prevention by industrial concerns and others. Such developments include better methods of assessing hospital hygiene, enhanced decontamination of the healthcare environment, biosynthetic tissue alternatives, antibiotic-impregnated medical devices and information technology that can help improve professional practice. Although promising, many of these have not been adequately evaluated in the clinical setting, highlighting the need for greater collaboration between industry and infection prevention and control practitioners to maximise the benefit of new products and to complement conventional approaches to HCAI prevention such as education, professional practice and the provision of better facilities.

    Spectroscopic evidence was obtained for molecular aggregation states to be controlled by the irradiation of light, which is off-resonant below the peak absorption energies of both monomers and well-grown J-aggregates. In low (undersaturated)-concentration aqueous solutions of porphyrin molecules (tetraphenyl porphyrin tetrasulfonic acid; TPPS) where the monomer absorbance dominates, irradiation with a 532 nm laser induces a decrease in the monomer absorbance and an increase in the aggregate absorbance. The increase in the absorbance of J-aggregates occurs in a broad spectral range associated with the increase in the number of not only variously sized oligomer aggregates but also aggregates structurally different from well-grown stable J-aggregates. In high-concentration solutions where the J-aggregate absorbance dominates, a blue shift of the absorption peak of J-aggregates is induced at the same 532 nm irradiation, corresponding to a decrease in the aggregation number or in the association energy. By contrast, for spin-coated polymer films of monomers and J-aggregates where molecules are immobile, these features are not observed. It is remarkable that the gradient force potential is smaller by more than seven orders of magnitude than the kinetic energy of the thermal motion of the molecule at room temperature, but the absorption change in solution indicating the increase in the number of aggregates is as large as ΔA ˜ 10-3 in magnitude.

    Implementation and adoption of efficient end-use technologies have proven to be one of the key measures for reducing greenhouse gas (GHG) emissions throughout the industries. In many cases, implementing energy efficiency measures is among one of the most cost effective investments that the industry could make in improving efficiency and productivity while reducing carbon dioxide (CO2) emissions. Over the years, there have been incentives to use resources and energy in a cleaner and more efficient way to create industries that are sustainable and more productive. With the working of energy programs and policies on GHG inventory and regulation, understanding and managing the costs associated with mitigation measures for GHG reductions is very important for the industry and policy makers around the world and in California. Successful implementation of applicable emerging technologies not only may help advance productivities, improve environmental impacts, or enhance industrial competitiveness, but also can play a significant role in climate-mitigation efforts by saving energy and reducing the associated GHG emissions. Developing new information on costs and savings benefits of energy efficient emerging technologies applicable in California market is important for policy makers as well as the industries. Therefore, provision of timely evaluation and estimation of the costs and energy savings potential of emerging technologies applicable to California is the focus of this report. The overall goal of the project is to identify and select a set of emerging and under-utilized energy-efficient technologies and practices as they are important to reduce energy consumption in industry while maintaining economic growth. Specifically, this report contains the results from performing Task 3 Technology Characterization for California Industries for the project titled Research Opportunities in Emerging and Under-Utilized Energy-Efficient Industrial Technologies, sponsored by

    HIV-1 infection frequently causes HIV-associated neurocognitive disorders (HAND) despite combination antiretroviral therapy (cART). Evidence is accumulating that components of cART can themselves be neurotoxic upon long-term exposure. In addition, abuse of psychostimulants, such as methamphetamine, seems to aggravate HAND and compromise antiretroviral therapy. However, the combined effect of virus and recreational and therapeutic drugs on the brain is poorly understood. Therefore, we exposed mixed neuronal-glial cerebrocortical cells to antiretrovirals (ARVs) (zidovudine [AZT], nevirapine [NVP], saquinavir [SQV], and 118-D-24) of four different pharmacological categories and to methamphetamine and, in some experiments, the HIV-1 gp120 protein for 24 h and 7 days. Subsequently, we assessed neuronal injury by fluorescence microscopy, using specific markers for neuronal dendrites and presynaptic terminals. We also analyzed the disturbance of neuronal ATP levels and assessed the involvement of autophagy by using immunofluorescence and Western blotting. ARVs caused alterations of neurites and presynaptic terminals primarily during the 7-day incubation and depending on the specific compounds and their combinations with and without methamphetamine. Similarly, the loss of neuronal ATP was context specific for each of the drugs or combinations thereof, with and without methamphetamine or viral gp120. Loss of ATP was associated with activation of AMP-activated protein kinase (AMPK) and autophagy, which, however, failed to restore normal levels of neuronal ATP. In contrast, boosting autophagy with rapamycin prevented the long-term drop of ATP during exposure to cART in combination with methamphetamine or gp120. Our findings indicate that the overall positive effect of cART on HIV infection is accompanied by detectable neurotoxicity, which in turn may be aggravated by methamphetamine.

    Mercury is a persistent, toxic metal that bio-accumulates within the food web and causes neurological damage and fetal defects in humans. The U.S. was the first country to regulate the leading anthropogenic source of mercury into the atmosphere: coal combustion for electric power generation. The U.S. EPA's 2005 Clean Air Mercury Rule (CAMR) was replaced and further tightened in 2012 by the Mercury and Air Toxics Standard (MATS), which required existing coal-fired utilities to reduce their mercury emissions by approximately 90% by 2015. Outside the U.S., the Governing Council of the United Nations Environment Programme (UNEP) has passed the legally binding Minamata global mercury treaty that compels its signatory countries to prevent and reduce the emission and release of mercury. The most mature technology for controlling mercury emissions from coal combustion is the injection into the flue gas of powdered activated carbon (PAC) adsorbents having chemically treated surfaces designed to rapidly oxidize and adsorb mercury. However, such PAC is known to have electrical properties that make it difficult to remove from flue gas via electrostatic precipitation, by far the most common particulate control technology used in countries such as the U.S., India, and China which rely heavily on coal for power generation. As a result, PAC used to control mercury emissions can be emitted into the atmosphere, the sub-micron fraction of which may result in unintended radiative forcing similar to black carbon (BC). Here, we estimate the potential increases in secondary BC emissions, those not produced from combustion but arising instead from the use of injected PAC for mercury emission reduction. We also calculate the radiative forcing associated with these secondary BC emissions by using a global atmospheric chemical transport model coupled with a radiative transfer model.

    This study aimed to describe severe infections with extensively drug-resistant Acinetobacter baumannii-calcoaceticus complex (XDR-ABC), as well as to investigate risk factors for mortality, in cancer patients. It was a retrospective study including all patients diagnosed with XDR-ABC bacteraemia during hospitalization in the intensive care unit of a cancer hospital between July 2009 and July 2013. Surveillance cultures were collected weekly during the study period, and clonality was analysed using pulsed field gel electrophoresis (PFGE). We analysed underlying diseases, oncology therapy, neutrophil counts, infection site and management of infection, in terms of their correlation with 30-day mortality. During the study period, 92 patients with XDR-ABC bacteraemia were identified, of whom 35 (38.0%) were patients with haematological malignancy. We identified XDR-ABC strains with four different profile patterns, 91.3% of patients harbouring the predominant PFGE type. Of the 92 patients with XDR-ABC bacteraemia, 66 (71.7%) had central line-associated bloodstream infections; infection occurred during neutropenia in 22 (23.9%); and 58 (63.0%) died before receiving the appropriate therapy. All patients were treated with polymyxin, which was used in combination therapy in 30 of them (32.4%). The 30-day mortality rate was 83.7%. Multivariate analysis revealed that septic shock at diagnosis of XDR-ABC infection was a risk factor for 30-day mortality; protective factors were receiving appropriate therapy and invasive device removal within the first 48 h. Among cancer patients, ineffective management of such infection increases the risk of death, more so than do features such as neutropenia and infection at the tumour site.

    OBJECTIVE To assess national trends in ectopic pregnancy incidence among assisted reproductive technology users and identify risk factors associated with ectopic pregnancy. METHODS We identified 553,577 pregnancies reported to the National ART Surveillance System between 2001 and 2011. Of those, 9,480 were ectopic, of which 485 were heterotopic. As a result of small numbers, ectopic and heterotopic pregnancies were combined for analysis. We assessed temporal trends in annual ectopic pregnancy rates using Poisson regression. We used log-binomial regression models with generalized estimating equations for correlated outcomes within clinics to calculate unadjusted and adjusted risk ratios for the association between ectopic pregnancy and selected patient characteristics and treatment factors. RESULTS The rate of ectopic pregnancy declined from 2.0% (n5735, 95% confidence interval [CI] 1.9–2.2) in 2001 to 1.6% (n=968, 95% CI 1.5–1.7) in 2011 (P for trend ,.001). The ectopic pregnancy rate ranged from 2.0% (n=7,469, 95% CI 1.9–2.0) for fresh, nondonor cycles to 1.0% (n=641, 95% CI 0.9–1.1) for fresh, donor cycles. Among fresh, nondonor cycles, the rate of ectopic pregnancy was 1.6% (95% CI 1.4–1.7) when one embryo was transferred compared with 1.7% (95% CI 1.7–1.8), 2.2% (95% CI 2.1–2.3), and 2.5% (95% CI 2.4–2.6) when two, three, or four or more embryos were transferred, respectively (adjusted risk ratios 1.11, 95% CI 0.94–0.30; 1.33, 95% CI 1.12–1.56; and 1.49, 95% CI 1.25–1.78). CONCLUSION Ectopic pregnancy incidence after assisted reproductive technology has decreased over time, but factors such as multiple embryo transfer increase the risk of ectopic pregnancy.

    Characterizing the solution structure of protein-polymer conjugates and protein-ligand interactions is important in fields such as biotechnology and biochemistry. Size-exclusion high-performance liquid chromatography with online classical light scattering (LS), refractive index (RI), and UV detection offers a powerful tool in such characterization. Novel methods are presented utilizing LS, RI, and UV signals to rapidly determine the degree of conjugation and the molecular mass of the protein conjugate. Baseline resolution of the chromatographic peaks is not required; peaks need only be sufficiently separated to represent relatively pure fractions. An improved technique for determining the polypeptide-only mass of protein conjugates is also described. These techniques are applied to determining the degree of erythropoietin glycosylation, the degree of polyethylene glycol conjugation to RNase A and brain-derived neurotrophic factor, and the solution association states of these molecules. Calibration methods for the RI, UV, and LS detectors will also be addressed, as well as online methods to determine protein extinction coefficients and dn/dc values both unconjugated and conjugated protein molecules.

    The objective of this study was to clarify the relationship between feeling upon awakening (FA) and time spent using information technology (IT) devices by children in kindergartens, elementary schools, and junior high schools in Shimane, Japan. In October 2008, a self-report survey was distributed to 2075 children in kindergartens (n = 261), elementary schools (n = 1162), and junior high schools (n = 652) in Shimane, Japan. The questionnaire gathered data on sex, school year, feeling upon awakening, and time spent using IT devices after school (television, videos on television, video games, personal computers, and cellular phones). After adjusting for sex and school year, data were analyzed by multivariate logistic regression analysis to calculate odds ratios (ORs) and 95% confidence intervals (CIs). A total of 2030 children completed this survey (response rate, 97.8%). Negative FA was associated with watching television more than 2 hours/day (OR = 1.51, 95% CI = 1.23-1.85), playing video games more than 30 minutes/day (1.50, 1.20-1.87), and using personal computers more than 30 minutes/day (1.35, 1.04-1.75). Time spent using IT devices affected the FA of children in kindergarten through junior high school. We propose the development of guidelines regarding the appropriate amount of time this population should spend using IT devices.

    The future challenges to medical and biological engineering, sometimes referred to as biomedical engineering or simply bioengineering, are many. Some of these are identifiable now and others will emerge from time to time as new technologies are introduced and harnessed. There is a fundamental issue regarding "Branding the bio/biomedical engineering degree" that requires a common understanding of what is meant by a B.S. degree in Biomedical Engineering, Bioengineering, or Biological Engineering. In this paper we address some of the issues involved in branding the Bio/Biomedical Engineering degree, with the aim of clarifying the Bio/Biomedical Engineering brand.

    Marine and hydrokinetic energy (MHK) and offshore wind devices are being developed and deployed in U.S. and international waters. Electric current flowing through subsea transmission cables associated with these devices will generate electromagnetic fields (EMF), which may interact with, and potentially impact, marine fishes. Some marine fishes can detect electric and/or magnetic fields and use them to navigate, orientate, and sense prey, mates and predators. Over the past five years there have been multiple comprehensive reviews and studies evaluating the potential vulnerability of marine fishes to EMF produced by MHK devices. Most documented effects involve sub-lethal behavioral responses of individual fish when in close proximity to EMF (e.g., fish being repelled by or attracted to fields). These reviews reach conclusions that the current state of research on this topic is still in its infancy and evaluations of potential impacts are associated with great uncertainty. A variety of MHK technologies are likely to be considered for deployment offshore of the Hawaiian Islands, and there is a need to be able to better predict and assess potential associated environmental impacts. The goal of this study was to provide a complementary piece to these previous reviews (e.g., Normandeau et al. 2011) by focusing on marine fish species in the Hawaii region. We compiled the relevant available information, then prioritized fish species as candidates for various paths of future research. To address this, we first developed a list of Hawaii Region Focal Species, which included fishes that are more likely to be sensitive to EMF. We then compiled species-specific information available in the literature on their sensitivity to EMF, as well as life history, movement and habitat use information that could inform an analysis of their likelihood of encountering EMF from subsea cables associated with MHK devices. Studies have only documented EMF sensitivity in 11 of the marine fish

    Commercial scale oil shale and oil sands development will require water, the amount of which will depend on the technologies adopted and the scale of development that occurs. Water in oil shale and oil sands country is already in scarce supply, and because of the arid nature of the region and limitations on water consumption imposed by interstate compacts and the Endangered Species Act, the State of Utah normally does not issue new water rights in oil shale or oil sands rich areas. Prospective oil shale and oil sands developers that do not already hold adequate water rights can acquire water rights from willing sellers, but large and secure water supplies may be difficult and expensive to acquire, driving oil shale and oil sands developers to seek alternative sources of supply. Produced water is one such potential source of supply. When oil and gas are developed, operators often encounter ground water that must be removed and disposed of to facilitate hydrocarbon extraction. Water produced through mineral extraction was traditionally poor in quality and treated as a waste product rather than a valuable resource. However, the increase in produced water volume and the often-higher quality water associated with coalbed methane development have drawn attention to potential uses of produced water and its treatment under appropriations law. This growing interest in produced water has led to litigation and statutory changes that must be understood and evaluated if produced water is to be harnessed in the oil shale and oil sands development process. Conversely, if water is generated as a byproduct of oil shale and oil sands production, consideration must be given to how this water will be disposed of or utilized in the shale oil production process. This report explores the role produced water could play in commercial oil shale and oil sands production, explaining the evolving regulatory framework associated with produced water, Utah water law and produced water regulation

    Full Text Available Background/Aim. Hepatitis C is an important sociomedical problem worldwide due to frequent progression to chronic disease, occurrence of liver cirrhosis and hepatocellular carcinoma. Standard pegylated interferon alfa 2a plus ribavirin therapy results in resolution of infection only in 50% of patients. The aim of this study was to determine the association of various factors with response to the therapy in patients with chronic hepatitis C virus (HCV infection. Age and sex of patients, inoculation risk factors, histopathological changes in the liver, viral load and HCV genotype were analyzed. Methods. The study included a group of 121 patients with chronic HCV infection. The treatment was carried out 24 weeks for virus genotype 2 and 3, and 48 weeks for genotype 1 and 4. The degree of histopathological changes in the liver was determined by hematoxylin and eosin staining, whereas polimerase chain reaction was used for HCV genotyping. Results. In the group of non-responding patients genotype 1 was represented with 100%, while in the other groups, although predominantly present, its percentage was lower. Unresponsiveness to therapy and relapse of disease were associated with higher viral load and advanced fibrosis. Intravenous use of psychoactive substances, as a risk factor, was present in a high percentage in the group of patients with sustained response, while blood transfusion and dialysis were leading risk factors in the group of relapse responders and non-responders. Conclusion. The results of our study showed that the treatment outcome of chronic HCV infection was associated with baseline HCV ribonucleic acid, HCV genotype, route of infection and the degree of histopathological changes in the liver.

    Full Text Available Purpose — the purpose of this article is to extend discussion towards the need and importance of joint degree programs in modern universities, introducing the perspective of the employers toward this question. Design/methodology/approach — the research was conducted to analyze the demand of joint degree programs from the perspective of employers, identify weak and strong aspects, opinion and demand for graduates of such programs. To achieve this purpose, a combination of theoretical and empirical methods was chosen: document analysis (previous studies, statistics was conducted and an online qualitative survey was organized. Findings — The analysis of articles, studies and statistics points out the challenges and threats faced by universities nowadays, forcing higher education institutions to find new ways to raise the quality of studies and raise the interest of employers to choose graduates from MRU, as well as the satisfaction of employers with their choice of employees. Theoretical analysis pointed out these challenges and requirements for the modern employee, summarised the challenges in preparation of IT field specialists. The conducted research results showed that the diploma of joint degree programs would not be treated as an advantage of possible employee from the perspective of employers in case some important aspects will not be taken into consideration by program creators. On the other hand, undeniably there are strong sides, such as knowledge in the fields of foreign language, international experience, innovativeness and creativeness of employees that would be treated as an advantage in the process of selection for positions of any technical support related positions. Research limitations/implications — employers, whose business activities are closely related to information technology, have been invited as experts. In addition, these experts have a good understanding of the specifics of joint degree programs. The received

    BH3-only protein, Bim, is a pro-apoptotic protein that mediates mitochondria-dependent cell death. However, the role of Bim in Helicobacter pylori-associated gastritis remains unclear. This study aimed to assess the cellular localization of Bim and its possible role in H. pylori-induced gastritis. The study was conducted on biopsy specimens obtained from 80 patients who underwent upper gastrointestinal endoscopy (H. pylori-negative: n=30, positive: n=50). Association between Bim mRNA expression and severity of gastritis was evaluated and the localization of Bim was examined by immunofluorescence. Bim mRNA expression was positively correlated with the degree of gastritis, as defined by the Sydney system. Immunohistochemical analysis confirmed increased Bim expression in H. pylori-infected gastric mucosa compared with uninfected mucosa in both humans and mice. Bim localized in myeloperoxidase- and CD138-positive cells of H. pylori-infected lamina propria and submucosa of the gastric tract, indicating that this protein is predominantly expressed in neutrophils and plasma cells. In contrast, Bim did not localize in CD20-, CD3-, or CD68-positive cells. Bim was expressed in the mitochondria, where it was partially co-localized with activated Bax and cleaved-PARP. In conclusion, Bim is expressed in neutrophils and plasma cells in H. pylori-associated gastritis, where it may participate in the termination of inflammatory response by causing mitochondria-mediated apoptosis in specific leucocytes.

    To summarize recent research on unintended consequences associated with implementation and use of health information technology (health IT). Included in the review are original empirical investigations published in English between 2014 and 2015 that reported unintended effects introduced by adoption of digital interventions. Our analysis focuses on the trends of this steam of research, areas in which unintended consequences have continued to be reported, and common themes that emerge from the findings of these studies. Most of the papers reviewed were retrieved by searching three literature databases: MEDLINE, Embase, and CINAHL. Two rounds of searches were performed: the first round used more restrictive search terms specific to unintended consequences; the second round lifted the restrictions to include more generic health IT evaluation studies. Each paper was independently screened by at least two authors; differences were resolved through consensus development. The literature search identified 1,538 papers that were potentially relevant; 34 were deemed meeting our inclusion criteria after screening. Studies described in these 34 papers took place in a wide variety of care areas from emergency departments to ophthalmology clinics. Some papers reflected several previously unreported unintended consequences, such as staff attrition and patients' withholding of information due to privacy and security concerns. A majority of these studies (71%) were quantitative investigations based on analysis of objectively recorded data. Several of them employed longitudinal or time series designs to distinguish between unintended consequences that had only transient impact, versus those that had persisting impact. Most of these unintended consequences resulted in adverse outcomes, even though instances of beneficial impact were also noted. While care areas covered were heterogeneous, over half of the studies were conducted at academic medical centers or teaching hospitals

  15. Physical Characterization of human centromeric regions using transformation-associated recombination cloning technology

    Energy Technology Data Exchange (ETDEWEB)

    Vladimir Larionov, Ph D

    2007-06-05

    A special interest in the organization of human centromeric DNA was stimulated a few years ago when two independent groups succeeded in reconstituting a functional human centromere, using constructs carrying centromere-specific alphoid DNA arrays. This work demonstrated the importance of DNA components in mammalian centromeres and opened a way for studying the structural requirements for de novo kinetochore formation and for construction of human artificial chromosomes (HACs) with therapeutic potential. To elucidate the structural requirements for formation of HACs with a functional kinetochore, we developed a new method for cloning of large DNA fragments for human centromeric regions that can be used as a substrate for HAC formation. This method exploits in vivo recombination in yeast (TAR cloning). In addition, a new strategy for the construction of alphoid DNA arrays was developed in our lab. The strategy involves the construction of uniform or hybrid synthetic alphoid DNA arrays by the RCA-TAR technique. This technique comprises two steps: rolling circle amplification of an alphoid DNA dimer and subsequent assembling of the amplified fragments by in vivo homologous recombination in yeast (Figure 1). Using this system, we constructed a set of different synthetic alphoid DNA arrays with a predetermined sequence varying in size from 30 to 140 kb and demonstrated that some of the arrays are competent in HAC formation. Because any nucleotide can be changed in a dimer before its amplification, this new technique is optimal for identifying the structural requirements for de novo kinetochore formation in HACs. Moreover, the technique makes possible to introduce into alphoid DNA arrays recognition sites for DNA-binding proteins. We have made the following progress on the studying of human centromeric regions using transformation-associated recombination cloning technology: i) minimal size of alphoid DNA array required for de novo kinetochore formation was estimated; ii

    Abdullah, Warith; Reddy, Remata

    From October 22nd to 30th, 2012 Hurricane Sandy was a huge storm of many abnormalities causing an estimated 50 billion dollars in damage. Tropical storm development states systems’ energy as product of warm sea surface temperatures (SST’s) and tropical cyclone heat potential (TCHP). Advances in Earth Observing (EO) technology, remote sensing and proxy remote sensing have allowed for accurate measurements of SST and TCHP information. In this study, we investigated rapid intensification of Sandy through EO applications for precipitable water vapor (PWAT), SST’s and TCHP during the period of October 27th. These data were obtained from NASA and NOAA satellites and NOAA National Buoy data center (NDBC). The Sensible Heat (Qs) fluxes were computed to determine available energy resulting from ocean-atmosphere interface. Buoy 41010, 120 NM east of Cape Canaveral at 0850 UTC measured 22.3 °C atmospheric temperatures and 27 °C SST, an interface of 4.7 °C. Sensible heat equation computed fluxes of 43.7 W/m2 at 982.0 mb central pressure. Sandy formed as late-season storm and near-surface air temperatures averaged > 21 °C according to NOAA/ESRL NCEP/NCAR reanalysis at 1000 mb and GOES 13 (EAST) geostationary water vapor imagery shows approaching cold front during October 27th. Sandy encountered massive dry air intrusion to S, SE and E quadrants of storm while travelling up U.S east coast but experienced no weakening. Cool, dry air intrusion was considered for PWAT investigation from closest sounding station during Oct. 27th 0900 - 2100 UTC at Charleston, SC station 72208. Measured PWAT totaled 42.97 mm, indicating large energy potential supply to the storm. The Gulf Stream was observed using NASA Short-term Prediction Research and Transition Center (SPoRT) MODIS SST analysis. The results show 5 °C warmer above average than surrounding cooler water, with > 25 °C water extent approximately 400 NM east of Chesapeake Bay and eddies > 26 °C. Results from sensible heat

    Factors influencing survival after head and neck cancer (HNC) include among others stage, age, and sex. More recently, human papillomavirus (HPV) positivity has been described as a favorable prognostic factor in relation to some HNCs. In this nationwide register-based cohort study of all 20 925 individuals diagnosed with squamous cell carcinoma of the head and neck (HNSCC) in Denmark 1978-2010, we investigate secular trends in all-cause five-year mortality after HNSCC according to the anticipated degree of association with HPV using a Cox proportional hazards model. Furthermore, we examine whether any trend over time differed according to sex, stage, and age at diagnosis. All-cause five-year mortality after HNSCC has decreased over time. The greatest decrease was seen in the last decade (2000-2010) among patients with HNSCC at sites estimated to be strongly associated with HPV, i.e. the base of the tongue and the tonsils, where a 28% decrease per five years (e.g. HRbase of tongue/tonsils=0.72; 95% CI 0.64-0.81) was observed. When examining sex- and age-specific time trends, the decrease in mortality was most pronounced among male patients and patients below 60 years at diagnosis. In contrast, no clear pattern was observed when examining five-year all-cause mortality trends according to stage. All-cause five-year mortality after HNSCC has decreased significantly in Denmark from 1978 to 2010, especially for HNSCCs at sites anticipated to be strongly associated with HPV, possibly due to an increasing proportion of HPV-positive HNSCCs.

    Objective To investigate the practice performance among associated degree nursing students and their perceptions of clinical learning environment. Methods The associated degree nursing students from 36 hospitals in Zhejiang province were recruited and investigated by using Clinical Learning Environment Inventory. Their practice performance was recorded based on the practice records. Results The total score of clinical learning environment was (173.07±16.02),and the factor scores were ranked as task location (26.68 ±3.98),interpersonal relation (26.01±4.60), student participation (25.64 ±4.44),work atmosphere and team culture (25.54±4.42) ,innovation (25.41±4.60),and individuation (24.50±5.36).The students' practice performance covered from 60.00 to 99.25 points. The scores showed skewness distribution,and the coefficient of skewness was -2.22. The students' practice performance was significantly higher in upper first-class hospitals than that in middle first-class or upper second-class hospitals. No relationship was found between the practice performance and their perceptions of clinical learning environment. Conclusion The score of practice performance among associated degree nursing students is relatively high,which is not correlated with their perceptions of clinical learning environment. It is suggested to apply formative assessment and third party evaluation system,pay close attention to the training of students' individuation and innovation,and strengthen particular management and thereby to improve the effectiveness of clinical practice.%目的 了解高职护理专业学生实习成绩情况,以及其对临床学习环境的评价.方法 采用便利抽样方法,选择在浙江省36家二级甲等以上教学医院实习的高职护理学生为调查对象,应用临床学习环境(氛围)评价量表、学生成绩登记表对其进行调查.结果 学生对临床学习环境评价总分为(173.07±16.02)分,各维度评分

    This article presents the history of establishment, functioning and the role of "Science and Technology"--quarterly of the Association of Polish Engineers in Great Britain--in shaping Polish technical thought in the environment of Polish engineers and technicians living in exile. The analysis of the content of the journal published in London in the years 1958-2008 made it evident that this official scientific organ of Polish technical intelligentsia edited in 500 copies reaches members of engineering, technical and scientific milieu across many continents. Despite the fact that Polish language dominates in the articles and thanks to the interdisciplinary character of their content - science and technology, biology, the humanities, sociology and others--the journal makes it possible for the reader to participate in an intellectual adventure. "Science and Technology" was created in 1958 on the initiative of Eng. Prof. Roman Wajda in Great Britain, with support of other Polish technical associations abroad, and embraced the achievements and organisational life of the Polish technical milieu dispersed around the world. On the basis of the London Society's archive materials and old annual volumes of the journal, the author listed editors-in-chief, composition of editorial committees, collaborators, determined editing costs, changeable periodicity, successive print shops, seats of editorial office that always followed the Association in Great Britain. She also showed the effort of a handful of members of editorial committees, working on a voluntary basis to obtain materials for the journal; the role of the journal linking Polish engineers and technicians in exile and its function as a link with the Country, as well as its role in the sphere of information and propaganda. Finally, the author made an analysis of the journal's content, focusing on categories of articles published in "Science and Technology" in the years 1958-2008.

    Brazosport College would be the first to admit that they owe the success of their Chemical Technology Program to the partnership that was developed between the college and the surrounding chemical industry. The college is a two-year institution located near the Texas Gulf Coast with more than twelve chemical companies in the immediate area. Dow Chemical is the largest, employing more than 5,000. Currently, the Science Department at Brazosport College offers associate of science degrees in biology, chemistry, and physics, and associate of applied science degrees in chemical technology and instrumentation technology to meet the needs of these industries. In addition, many students enroll in classes to prepare for specific occupations or to build their skills for employment. This may only require the student to take a few courses. The current Chemical Technology Program addresses skills needed for both laboratory and process technician jobs in the chemical industry. An Associate of Applied Science Degree in Chemical Technology is offered with either a laboratory or a process option. These programs were developed with input from the chemical industry, and the college trains all new process employees for BASF and Dow. Additionally, the college does customized flexible-entry training in process operations and laboratory analysis for these and several other companies.

    Food processing alters food from its natural state for safety, convenience, taste or palatability. Previous research suggests that industrially processed foods, and diets high in these products, tend to be less healthful. However, most previous work is based on household, rather than individual-level, data. Little has been reported on the relationship between processed food consumption and markers of health; or on socio-demographic correlates of processed food consumption. Our objective was to describe: the nutritional content of foods classified according to degree of processing; the nutritional content of diets with different relative intakes of processed foods; the socio-demographic characteristics of individuals with different relative intakes of processed foods; and the association between intake of processed foods and body weight. Secondary analysis of data from the UK National Diet and Nutrition Survey (2008-12), a large national cross-sectional study of diet. Dietary information was collected using four-day, unweighed, food-diaries. Foods were classified as: unprocessed or minimally processed (MPF; foods with no processing or mostly physical processes applied to single whole foods), processed ingredients (PI; extracted and purified components of single whole foods), or ultra-processed food products (UPF; products produced from industrial combining of MPF and PI). Two thousand one hundred seventy four adults were included. MPF and diets high in these foods, had the most healthful nutritional profile. UPF did not necessarily have the least healthful nutritional profile, but diets high in these foods did. Women, and older adults consumed more energy from MPF, and less from UPF. Those living in lower occupation social class households consumed less energy from MPF, but no more from UPF. Only higher intake of PI was consistently, inversely, associated with body weight. This is the first study to explore correlates of processed food consumption, using individual

  14. Why do different people choose different university degrees? Motivation and the choice of degree

    Science.gov (United States)

    Skatova, Anya; Ferguson, Eamonn

    2014-01-01

    Different people choose undergraduate degrees to study at university for different reasons. To date, there have been limited attempts to identify individual differences in motivation that drive undergraduate degree choice. We identified that people choose university degrees for four reasons: career concerns (Career), intrinsic interest in the subject (Interest), an opportunity to help others (Helping) and because they are looking for an easy option to get into higher education (Loafing). We investigated whether these motivations apply to the choice of undergraduate degree in two samples: (1) undergraduate (N = 989) and (2) prospective (N = 896) students. We developed the Motivations Influencing Course Choice (MICC) questionnaire to measure these motivations. Scales of Helping, Career, Loafing, and Interest showed good psychometric properties, showed validity with respect to general life goals and personality traits, and predicted actual and prospective degree choices. We demonstrated that medical degrees were chosen due to a mixture of Helping and Career, while engineering degrees were associated with Career and low Interest in the degree. The choice of arts and humanities degrees was driven by Interest and low concern about future career, accompanied with high Loafing. We also demonstrated gender differences: females were high in Helping (both samples) and Interest (only in the undergraduate sample) motivation, while males scored higher in Career (only in the undergraduate sample) and Loafing (both samples). The findings can feed into both theoretical accounts of proximal motivation as well as provide help to improve degree programmes at universities and support better career advice. PMID:25431561

    Full Text Available This study aims to examine the relationship between a responsive and aproactive market orientation and the degree of novelty. Data obtainedvia an Internet survey were analysed using structural equation modelling.An analysis of 325 Slovenian firms reveals that only a proactivemarket orientation is positively related to the degree of novelty. Whilethere is no evidence of statistically significant differences in the examinedrelationships given the firm size and environmental characteristics,separate analyses in each group indicate that a proactive market orientationmay be more important for small firms and firms operatingamidst a higher level of technological turbulence. This study suggeststhat a distinction between a responsive and a proactive market orientationis important for a better understanding of the effect of a marketorientation on the degree of novelty.

    Aspasia A. Nisiotou

    2015-01-01

    Full Text Available Vineyard- and winery-associated lactic acid bacteria (LAB from two major PDO regions in Greece, Peza and Nemea, were surveyed. LAB were isolated from grapes, fermenting musts, and winery tanks performing spontaneous malolactic fermentations (MLF. Higher population density and species richness were detected in Nemea than in Peza vineyards and on grapes than in fermenting musts. Pediococcus pentosaceus and Lactobacillus graminis were the most abundant LAB on grapes, while Lactobacillus plantarum dominated in fermenting musts from both regions. No particular structure of Lactobacillus plantarum populations according to the region of origin was observed, and strain distribution seems random. LAB species diversity in winery tanks differed significantly from that in vineyard samples, consisting principally of Oenococcus oeni. Different strains were analysed as per their enological characteristics and the ability to produce biogenic amines (BAs. Winery-associated species showed higher resistance to low pH, ethanol, SO2, and CuSO4 than vineyard-associated isolates. The frequency of BA-producing strains was relatively low but not negligible, considering that certain winery-associated Lactobacillus hilgardii strains were able to produce BAs. Present results show the necessity of controlling the MLF by selected starters in order to avoid BA accumulation in wine.

    This study explored whether technology adoption and changes in management practices were associated with farm structure, household, and farmer characteristics and to identify processes that may foster productivity and sustainability of small-scale dairy farming in the central highlands of Mexico. Factor analysis of survey data from 44 smallholders identified three factors-related to farm size, farmer's engagement, and household structure-that explained 70 % of cumulative variance. The subsequent hierarchical cluster analysis yielded three clusters. Cluster 1 included the most senior farmers with fewest years of education but greatest years of experience. Cluster 2 included farmers who reported access to extension, cooperative services, and more management changes. Cluster 2 obtained 25 and 35 % more milk than farmers in clusters 1 and 3, respectively. Cluster 3 included the youngest farmers, with most years of education and greatest availability of family labor. Access to a network and membership in a community of peers appeared as important contributors to success. Smallholders gravitated towards easy to implement technologies that have immediate benefits. Nonusers of high investment technologies found them unaffordable because of cost, insufficient farm size, and lack of knowledge or reliable electricity. Multivariate analysis may be a useful tool in planning extension activities and organizing channels of communication to effectively target farmers with varying needs, constraints, and motivations for change and in identifying farmers who may exemplify models of change for others who manage farms that are structurally similar but performing at a lower level.

    2017-07-08

    Immature, vegetable-like fruits are produced by crops of great economic importance, including cucumbers, zucchini, eggplants and bell peppers, among others. Because of their high respiration rates, associated with high rates of dehydration and metabolism, and their susceptibility to chilling injury (CI), vegetable fruits are highly perishable commodities, requiring particular storage conditions to avoid postharvest losses. This review focuses on the oxidative stress that affects the postharvest quality of vegetable fruits under chilling storage. We define the physiological and biochemical factors that are associated with the oxidative stress and the development of CI symptoms in these commodities, and discuss the different physical, chemical and biotechnological approaches that have been proposed to reduce oxidative stress while enhancing the chilling tolerance of vegetable fruits.

  4. Factors associated with computer and Internet technology implementation in biology, chemistry, and physics education in Turkish secondary schools

    The main purposes of the research were to identify computer and Internet use by biology, chemistry and physics teachers in Turkish secondary schools and identify factors associated with computer and Internet technology. To this end, survey documents were sent by the Provincial Directorate of National Education to 250 selected schools' administrators for further distribution. Administrators were asked to complete the "Computer and Internet Use: School Survey," and to distribute the "Science Teacher Computer and Internet Use" surveys to the two teachers who teach science class. Surveys were then returned to the General Directorate of Educational Technologies. Research findings showed that computer and Internet use has not occurred effectively. Computers were first introduced to Turkish schools in 1984; unfortunately the current situation of computer and Internet use in science education is not at the projected earlier point in time. Considering the fact that science teachers' participation in technology-related professional development program is higher than other subject teachers, the use of computer and Internet technologies in Turkish secondary schools is still at its early stages. Lack of computer knowledge and not knowing how to integrate computers into education were the major factors reported. With regard to computer and Internet use, a regression model for Turkish schools, which includes access and knowledge, explains a large part of the variance in study results. There was a significant relationship between computer attitude (computer liking, usefulness, and confidence) and computer and Internet use. Although there was a significant negative relationship between Internet and computer uses and the attitudinal component, computer anxiety, it did not deter individuals from expressing a desire to engage in computer use in education.

    Campylobacter jejuni is the leading cause of food- and water-borne illness world-wide. The membrane-associated proteome of a recent C. jejuni gastrointestinal isolate (JHH1) was generated by sodium carbonate precipitation and ultracentrifugation followed by 2-DE and MALDI-TOF MS as well as 2-DLC (strong cation exchange followed by RP chromatography) of trypsin digests coupled to MS/MS (2-DLC/MS/MS). 2-DE/MS identified 77 proteins, 44 of which were predicted membrane proteins, while 2-DLC/MS/MS identified 432 proteins, of which 206 were predicted to be membrane associated. A total of 453 unique proteins (27.4% of the C. jejuni theoretical proteome), including 187 bona fide membrane proteins were identified in this study. Membrane proteins were also compared between C. jejuni JHH1 and ATCC 700297 to identify factors potentially associated with increased gastrointestinal virulence. We identified 28 proteins that were significantly (>two-fold) more abundant in, or unique to, JHH1, including eight proteins involved in chemotaxis signal transduction and flagellar motility, the amino acid-binding surface antigens CjaA and CjaC, and four outer membrane proteins (OMPs) of unknown function (Cj0129c, Cj1031, Cj1279c, and Cj1721c). Immunoblotting using convalescent patient sera generated post-gastrointestinal infection revealed 13 (JHH1) and 12 (ATCC 700297) immunoreactive proteins. These included flagellin (FlaA) and CadF as well as Omp18, Omp50, Cj1721c, PEB1A, PEB2, and PEB4A. This study provides a comprehensive analysis of membrane-associated proteins from C. jejuni.

    2016-09-01

    Full Text Available Mucosal infection by the human papillomavirus (HPV is responsible for a growing number of malignancies, predominantly represented by cervical cancer and oropharyngeal squamous cell carcinoma. Because of the prevalence of the virus, persistence of infection, and long latency period, novel and low-cost methods are needed for effective population level screening and monitoring. We review established methods for screening of cervical and oral cancer as well as commercially-available techniques for detection of HPV DNA. We then describe the ongoing development of microfluidic nucleic acid-based biosensors to evaluate circulating host microRNAs that are produced in response to an oncogenic HPV infection. The goal is to develop an ideal screening platform that is low-cost, portable, and easy to use, with appropriate signal stability, sensitivity and specificity. Advances in technologies for sample lysis, pre-treatment and concentration, and multiplexed nucleic acid detection are provided. Continued development of these devices provides opportunities for cancer screening in low resource settings, for point-of-care diagnostics and self-screening, and for monitoring response to vaccination or surgical treatment.

    This research reports on a new innovation in chemical measurement technology that combines Open-path Fourier Transform Infrared (OP-FTIR) spectroscopy with computed tomography to create two-dimensional maps of air contaminants that are both spatially and temporally resolved. This method has been evaluated with numerical studies that tested different iterative reconstruction algorithms and OP-FTIR configurations. The success of this system for characterizing the flow of contaminants in air, exposure assessment, emission monitoring and leak detection, was closely linked to the choice of reconstruction algorithm and configuration. A systematic method was developed to evaluate these parameters using static and time series test maps under ideal and non-ideal sampling conditions. Concentration map quality was evaluated using qualitative and quantitative criteria. Map reconstruction quality using different algorithms configurations was found to be intimately related to the complexity of the test maps. The results of this research underscored the need to thoroughly test the system through numerical studies prior to field implementation; a wide variety of concentration maps, relevant to the application, should be tested under both ideal and non-ideal sampling conditions.

    Synthetic aperture radar remote sensing captures various fine-scale features on the ocean surface such as coastal discharges, oil pollution, vessel traffic, algal blooms and sea slicks. Although numerous factors potentially affect the synthetic aperture radar imaging process, the influence of biogenic and anthropogenic surfactants has been suggested as one of the primary parameters, especially under relatively low wind conditions. Surfactants have a tendency to dampen the short gravity-capillary ocean waves causing the sea surface to smoothen, thus allowing the radar to detect areas of surfactants. Surfactants are found in sea slicks, which are the accumulation of organic material shaped as elongated bands on the ocean's surface. Sea slicks are often observable with the naked eye due to their glassy appearance and can also be seen on synthetic aperture radar images as dark scars. While the sources of surfactants can vary, some are known to be of marine bacteria origin. Countless numbers of marine bacteria are present in the oceanic environment, and their biogeochemical contributions cannot be overlooked. Not only does marine-bacteria produce surfactants, but they also play an important role in the transformation of surfactants. In this study, we profiled the surfactant-associated bacteria composition within the biogenic thin layer of the ocean surface more commonly referred as the sea surface microlayer. Bacterial samples were collected from the sea surface microlayer for comparative analysis from both within and outside of sea slick areas as well as the underlying subsurface water. The bacterial microlayer sampling coincided with synthetic aperture radar satellite, RADARSAT-2, overpasses to demonstrate the simultaneous in-situ measurements during a satellite image capture. The sea surface microlayer sampling method was designed to enable aseptic bacterial sampling. A 47 mm polycarbonate membrane was utilized at each sampling site to obtain a snapshot of the

    Zhu, Lixia; Xue, Julan

    2017-03-01

    In this study, we performed a pilot-scale evaluation of the enological characteristics of indigenous Saccharomyces cerevisiae strains associated with Msalais, a traditional Chinese wine produced by a unique technology of boiling grape juice prior to spontaneous fermentation. Technical and sensory characteristics of top ten indigenous strains previously identified by us by screening a collection of 436 indigenous S. cerevisiae strains (Zhu et al. 2016) were assayed in a traditional craft workshop (TCW) and a modern plant (MP). The use of these strains reduced the spontaneous fermentation (Spo F) period by 6-15 days, and resulted in higher sugar and lower alcohol content in TCW Msalais than in MP Msalais. Sensory scores of Msalais fermented by the ten strains were higher than those of wine produced with a commercial strain cy3079, varying in TCW fermentations and significantly different from Spo F, but homogenous for all MP fermentations. Four strains were extensively screened for use in industrial Msalais production. We conclude that modern technology homogenizes enological traits of indigenous strains while traditional craftsmanship maintains their enological diversity. Some strains domesticated in the course of both processes are suitable for industrial Msalais production.

    Full Text Available The maps of the form f( x = ∑ i=1 n a i ⋅x⋅ b i , called 1-degree maps, are introduced and investigated. For noncommutative algebras and modules over them 1-degree maps give an analogy of linear maps and differentials. Under some conditions on the algebra 𝒜 , contractibility of the group of 1-degree isomorphisms is proved for the module l 2 ( 𝒜 . It is shown that these conditions are fulfilled for the algebra of linear maps of a finite-dimensional linear space. The notion of 1-degree map gives a possibility to define a nonlinear Fredholm map of l 2 ( 𝒜 and a Fredholm manifold modelled by l 2 ( 𝒜 . 1-degree maps are also applied to some problems of Markov chains.

Our main theorem bounds the degree of the generators of a semigroup associated with a graph with first Betti number g by g + 1. Furthermore, this bound is effective for many graphs. In particular, the caterpillar graph with g loops has generators of degree g + 1 for even g and of degree g for odd g.

    2006-09-01

    Full Text Available This paper presents a study of societal costs related to public health due to the degradation of air quality and the lack of physical activity, both affected by our built environment. The paper further shows road safety as another public health concern. Traffic fatalities are the number one cause of death in the world. Traffic accidents result in huge financial loss to the people involved and the related public health cost is a significant part of the total societal cost. Motor vehicle exhausts and industrial emissions, gasoline vapors, and chemical solvents as well as natural sources emit nitrogen oxides and volatile organic compounds, which are precursors to the formation of ground-level Ozone. High concentration values of ground-level Ozone in hot summer days produce smog and lead to respiratory problems and loss in worker’s productivity. These factors and associated economic costs to society are important in establishing public policy and decision-making for sustainable transportation and development of communities in both industrialized and developing countries. This paper presents new science models for predicting ground-level Ozone and related air quality degradation. The models include predictor variables of daily climatological data, traffic volume and mix, speed, aviation data, and emission inventory of point sources. These models have been implemented in the user friendly AQMAN computer program and used for a case study in Northern Mississippi. Lifecycle benefits from reduced societal costs can be used to implement sustainable transportation policies, enhance investment decision-making, and protect public health and the environment.

  7. Classification of infrastructure networks by neighborhood degree distribution

    CERN Document Server

    Giustolisi, O; Ridolfi, L

    2016-01-01

    A common way of classifying network connectivity is the association of the nodal degree distribution to specific probability distribution models. During the last decades, researchers classified many networks using the Poisson or Pareto distributions. Urban infrastructures, like transportation (railways, roads, etc.) and distribution (gas, water, energy, etc.) systems, are peculiar networks strongly constrained by spatial characteristics of the environment where they are constructed. Consequently, the nodal degree of such networks spans very small ranges not allowing a reliable classification using the nodal degree distribution. In order to overcome this problem, we here (i) define the neighborhood degree, equal to the sum of the nodal degrees of the nearest topological neighbors, the adjacent nodes and (ii) propose to use neighborhood degree to classify infrastructure networks. Such neighborhood degree spans a wider range of degrees than the standard one allowing inferring the probabilistic model in a more re...

    Frequently, it is argued that the microstates responsible for the Bekenstein-Hawking entropy should arise from some physical degrees of freedom located near or on the black hole horizon. In this essay, we elucidate that instead entropy may emerge from the conversion of physical degrees of freedom, attached to a generic boundary, into unobservable gauge degrees of freedom attached to the horizon. By constructing the reduced phase space, it can be demonstrated that such a transmutation indeed takes place for a large class of black holes, including Schwarzschild.

    Bassler, Kevin E; Erdős, Péter L; Miklós, István; Toroczkai, Zoltán

    2015-01-01

    Many real-world networks exhibit correlations between the node degrees. For instance, in social networks nodes tend to connect to nodes of similar degree. Conversely, in biological and technological networks, high-degree nodes tend to be linked with low-degree nodes. Degree correlations also affect the dynamics of processes supported by a network structure, such as the spread of opinions or epidemics. The proper modelling of these systems, i.e., without uncontrolled biases, requires the sampling of networks with a specified set of constraints. We present a solution to the sampling problem when the constraints imposed are the degree correlations. In particular, we develop an efficient and exact method to construct and sample graphs with a specified joint-degree matrix, which is a matrix providing the number of edges between all the sets of nodes of a given degree, for all degrees, thus completely specifying all pairwise degree correlations, and additionally, the degree sequence itself. Our algorithm always pro...

    Full Text Available Aims: To examine the pattern and extent of cardiovascular developmental alterations among children conceived by assisted reproductive technology (ART and its association with potential confounders. Methods: The present study was a prospective single-blind pilot design lasting 15 months. The ART group was recruited by a non-random, consecutive sample on the basis of the unique personal identification number assigned to ART children, whereas spontaneous conception controls were recruited by a population-based random sample from the same hospital by age. Echocardiography was available for the measurement of 128 ART children and 100 controls with respect to cardiovascular geometric morphology and cardiac function. Results: The majority of cardiac geometric morphology parameters were comparable among the study groups (P>0.05, except for significant increases in left ventricular (LV relative wall thickness (P=0.038, LV mass index (P=0.005 and LV remodeling index (P=0.005 in ART children after adjustment for age, gender, body surface area and heart rate. The results showed similarity in LV systolic function characterized by ejection fraction (P=0.140 and shortening fraction (P=0.167 between the groups. However, ART children had a significant tendency toward a decrease in mitral A (P=0.008 and mitral E′ (P=0.012 compared with controls after adjusting for confounders. Additionally, Cox analysis suggested an independent association (PConclusion: Our findings support the presence of remodeling in the left cardiac geometric morphology and diastolic dysfunction and the absence of any change to the aortocoronary morphometry or systolic function in ART children compared with controls, which may be independently associated with the anthropometrics and perinatal outcomes in addition to the ART procedure.

    We propose a generalization of the concept of assortativity based on the tensorial representation of multilayer networks, covering the definitions given in terms of Pearson and Spearman coefficients. Our approach can also be applied to weighted networks and provides information about correlations considering pairs of layers. By analyzing the multilayer representation of the airport transportation network, we show that contrasting results are obtained when the layers are analyzed independently or as an interconnected system. Finally, we study the impact of the level of assortativity and heterogeneity between layers on the spreading of diseases. Our results highlight the need of studying degree-degree correlations on multilayer systems, instead of on aggregated networks.

    Practice tools such as health information technology (HIT) have the potential to support care processes, such as communication between health care providers, and influence care for "ambulatory care-sensitive conditions" (ACSCs). ACSCs are conditions for which good outpatient care can potentially prevent the need for hospitalization. To date, associations between such primary care practice capabilities and hospitalizations for ambulatory care-sensitive conditions have been primarily limited to smaller, local studies or unique delivery systems rather than nationally representative studies of primary care physicians in the United States. We analyzed a nationally representative sample of 1,819 primary care physicians who responded to the Center for Studying Health System Change's Physician Survey. We linked 3 years of Medicare claims (2007 to 2009) with these primary care physician survey respondents. This linkage resulted in the identification of 123,760 beneficiaries with one or more of 4 ambulatory care-sensitive chronic conditions (diabetes, chronic obstructive pulmonary disease, asthma, and congestive heart failure) for whom these physicians served as the usual provider. Key independent variables of interest were physicians' practice capabilities, including communication with specialists, use of care managers, participation in quality and performance measurement, use of patient registries, and HIT use. The dependent variable was a summary measure of ambulatory care-sensitive hospitalizations for one or more of these 4 conditions. Higher provider-reported levels of communication between primary care and specialist physicians were associated with lower rates of potentially avoidable hospitalizations. While there was no significant main effect between HIT use and ACSC hospitalizations, the associations between interspecialty communication and ACSC hospitalizations were magnified in the presence of higher HIT use. For example, patients in practices with both the

    With the introduction of ICD-10 as the standard for diagnostics, it becomes necessary to develop an electronic representation of its complete content, inherent semantics, and coding rules. The authors' design relates to the current efforts by the CEN/TC 251 to establish a European standard for hierarchical classification systems in health care. The authors have developed an electronic representation of ICD-10 with the eXtensible Markup Language (XML) that facilitates integration into current information systems and coding software, taking different languages and versions into account. In this context, XML provides a complete processing framework of related technologies and standard tools that helps develop interoperable applications. XML provides semantic markup. It allows domain-specific definition of tags and hierarchical document structure. The idea of linking and thus combining information from different sources is a valuable feature of XML. In addition, XML topic maps are used to describe relationships between different sources, or "semantically associated" parts of these sources. The issue of achieving a standardized medical vocabulary becomes more and more important with the stepwise implementation of diagnostically related groups, for example. The aim of the authors' work is to provide a transparent and open infrastructure that can be used to support clinical coding and to develop further software applications. The authors are assuming that a comprehensive representation of the content, structure, inherent semantics, and layout of medical classification systems can be achieved through a document-oriented approach.

    Increasingly, technology (text, e-mail, and social media) is being used in dating relationships to stalk, control, threaten, and harass dating partners. This study examines risk and promotive factors associated with technology-delivered dating aggression (TDA) and relations between types of violence (physical dating/nondating, community violence, and TDA). Participants (14-20 years old) self-administered a computerized survey as part of a larger study at an urban emergency department. The study includes 210 youth who reported having a dating partner in the past 2 months. About 48.1% of participants reported TDA in the past 2 months. Mindfulness was negatively associated with TDA. Youth reporting TDA were more likely to report physical dating violence and community violence exposure. TDA is not an isolated occurrence and is positively associated with in-person violence among adolescents. Associations between TDA, risk and promotive factors, and other forms of violence can help identify avenues for targeting interventions.

    Oocysts of the protozoan pathogen Cryptosporidium parvum are of particular concern for riverbank filtration (RBF) operations because of their persistence, ubiquity, and resistance to chlorine disinfection. At the Russian River RBF site (Sonoma County, CA), transport of C. parvum oocysts and oocyst-sized (3 ??m) carboxylate-modified microspheres through poorly sorted (sorting indices, ??1, up to 3.0) and geochemically heterogeneous sediments collected between 2 and 25 m below land surface (bls) were assessed. Removal was highly sensitive to variations in both the quantity of extractable metals (mainly Fe and Al) and degree of grain sorting. In flow-through columns, there was a log-linear relationship (r2 = 0.82 at p < 0.002) between collision efficiency (??, the probability that colloidal collisions with grain surfaces would result in attachment) and extractable metals, and a linear relationship (r2 = 0.99 at p < 0.002) between ?? and ??1. Collectively, variability in extractable metals and grain sorting accounted for ???83% of the variability in ?? (at p < 0.0002) along the depth profiles. Amendments of 2.2 mg L-1 of Russian River dissolved organic carbon (DOC) reduced ?? for oocysts by 4-5 fold. The highly reactive hydrophobic organic acid (HPOA) fraction was particularly effective in re-entraining sediment-attached microspheres. However, the transport-enhancing effects of the riverine DOC did not appear to penetrate very deeply into the underlying sediments, judging from high ?? values (???1.0) observed for oocysts being advected through unamended sediments collected at ???2 m bls. This study suggests that in evaluating the efficacy of RBF operations to remove oocysts, it may be necessary to consider not only the geochemical nature and size distribution of the sediment grains, but also the degrees of sediment sorting and the concentration, reactivity, and penetration of the source water DOC. ?? 2011 American Chemical Society.

    Full Text Available Abstract Background Brain-computer interface methodology based on self-regulation of slow-cortical potentials (SCPs of the EEG (electroencephalogram was used to assess conditional associative learning in one severely paralyzed, late-stage ALS patient. After having been taught arbitrary stimulus relations, he was evaluated for formation of equivalence classes among the trained stimuli. Methods A monitor presented visual information in two targets. The method of teaching was matching to sample. Three types of stimuli were presented: signs (A, colored disks (B, and geometrical shapes (C. The sample was one type, and the choice was between two stimuli from another type. The patient used his SCP to steer a cursor to one of the targets. A smiley was presented as a reward when he hit the correct target. The patient was taught A-B and B-C (sample – comparison matching with three stimuli of each type. Tests for stimulus equivalence involved the untaught B-A, C-B, A-C, and C-A relations. An additional test was discrimination between all three stimuli of one equivalence class presented together versus three unrelated stimuli. The patient also had sessions with identity matching using the same stimuli. Results The patient showed high accuracy, close to 100%, on identity matching and could therefore discriminate the stimuli and control the cursor correctly. Acquisition of A-B matching took 11 sessions (of 70 trials each and had to be broken into simpler units before he could learn it. Acquisition of B-C matching took two sessions. The patient passed all equivalence class tests at 90% or higher. Conclusion The patient may have had a deficit in acquisition of the first conditional association of signs and colored disks. In contrast, the patient showed clear evidence that A-B and B-C training had resulted in formation of equivalence classes. The brain-computer interface technology combined with the matching to sample method is a useful way to assess various

    1999-01-01

    This small, non-contact optical sensor increases the capability and flexibility of computer controlled machines by detecting its relative position to a workpiece in all six degrees of freedom (DOF). At a fraction of the cost, it is over 200 times faster and up to 25 times more accurate than competing 3-DOF sensors. Applications range from flexible manufacturing to a 6-DOF mouse for computers. Until now, highly agile and accurate machines have been limited by their inability to adjust to changes in their tasks. By enabling them to sense all six degrees of position, these machines can now adapt to new and complicated tasks without human intervention or delay--simplifying production, reducing costs, and enhancing the value and capability of flexible manufacturing.

    The volume of global stranded natural gas reserves is impressive totalling more than a third of the world's proven natural gas reserves. In Brazil, recent discoveries operated by PETROBRAS with the share of other companies indicate the tendency of incorporating stranded gas reserves (associated or not) to the country's total reserves. The objective of this study is to perform a technical and economic analysis of the implementation of small-scale GTL technology for the exploitation of stranded associated natural gas offshore in Brazil. Thus, the study initially held a survey of the processes of gasification and the manufacturers of technologies and projects based on these processes, specifically for offshore applications. Then, the offshore environment conditions were examined. After the confrontation of the available technologies and the operational conditions, one technology was chosen to be assessed by the economic analysis. The results show that GTL offshore option becomes feasible for the minimum oil price of approximately $50.00 per barrel. This price is greater than the value of robustness adopted by PETROBRAS, however there is still the possibility of cost reductions for the feasibility of new technologies. (author)

  10. Improving Scientific Writing in Undergraduate Geosciences Degrees Through Peer Review

    Science.gov (United States)

    Day, E. A.; Collins, G. S.; Craig, L.

    2016-12-01

    In the British educational system, students specialise early. Often geoscience undergraduates have not taken a class that requires extended writing since they were sixteen years old. This can make it difficult for students to develop the written skills necessary for a geoscience degree, which often has assessments in the form of essays and reports. To improve both the writing and editing skills of our undergraduates we have introduced a peer review system, in which seniors review the work of first year students. At Imperial College London we set written coursework in every year of the degree. Communication is taught and assessed in many courses. There are two major modules with substantial written components that bookend the undergraduate degree at Imperial; the freshmen all write an assessed essay, while all seniors take 'Science Communication', a course that aims to prepare them for a range of possible careers. In the 2015-16 academic year we linked these courses by introducing a modified form of peer marking and instruction. Seniors had to complete reviews of draft first year essays for credit in Science Communication. These reviews are completed for the department 'journal' and introduce the first and fourth years to the nature of peer review. Seniors learn how to critically, but kindly, evaluate the work of other students, and are also prepared for potentially submitting their senior theses to journals. Reviews were managed by volunteer seniors, who acted as associate editors. They allocated anonymous reviewers and wrote decision letters, which were sent to the freshmen before their final assessed essay submission. Ultimately the fourth year reviews were formally assessed and graded by members of staff, as were the revised and resubmitted first year essays. Feedback for both courses has improved since the introduction of student reviews of essays. The markers of the freshman essay have also commented on the improvement in the standard of the writing and a

    Full Text Available The main objective of the study is to establish the satisfaction degree of the heavy commercial vehicles market customers. This scientifical endeavour is justified by the major importance given by the producers and distributors of such vehicles to the beneficiaries’ satisfaction, a hich importance factor in the product development, customer relations inprovement and market share growth. After the 2008-2009 financial crisis, when the Romanian heavy commercial vehicles market collapsed, the growth trend was linear and moderat, but the market structure changed significantly. Having on one hand high technological costs, generated by the European legislation on pllution reduction and road safety and, on the other hand, the beneficiaries’ price pressure, the top producers from the deveoped countries focused on the optimization of the cutomers’ satisfaction degree and the development of their loyalty towards the brand. In order to achieve this, there has been developed a selective qualitative research, in the form of a questionnaire, among the most important customers of MHS Truck & Bus SRL – the importer of MAN trucks in Romania. The questions were directed towards obtaining informations regarding the customers’ product perception, identifying the main acquisition motivations and finding the main issues in successfully implementing the main politics of the relational maketing. The obtained results generally showed a good satisfaction result, the main complaints regarding subjects indirectly linked to the distribution, like service performance or road assistance.

    2010-09-15

    Increasing population and economic growth in developing countries has changed their energy consumption patterns. So, the conventional systems of energy supply have become inadequate to deal with rising energy demand. Iran has great reservoirs of natural gas and its natural gas usage is far more than average international standard. Dominance of natural gas share in energy basket in Iran, make it necessary to consider energy efficient technologies and solutions for this domain. In this study new technologies for increasing energy efficiency (EE) in natural gas delivery and consumption sub sectors are discussed and evaluated according to available infrastructures in Iran.

    2015-12-01

    Full Text Available The electricity sector represents the sector with the greatest impact in terms of producing climate change, mainly due to the greenhouse gas emissions generated through the burning of fossil fuels. It is not however the only negative aspect associated to the classic technologies of electricity production. This paper aims to assess the economic and environmental aspects associated to the technologies for the electricity production from conventional sources and as a conclusion of the research it will also propose certain specific measures designed to mitigate their impacts. Therefore, the analysis will focus on economic issues, such as limited resources of fuels and the significant fluctuation in fuel prices, low energy efficiency, environmental protection expenditures and health issues as a result of the pollution generated by the electricity production and environmental aspects related primarily to the burning of fossil fuels, but also to extraction, transport and storage, aspects concerning the management of waste generated by the energy sector or to the risks associated with the process of producing electricity. In the final part of the paper a few measures will be proposed to mitigate the impact on the environment and economic development of such technologies, as well as increasing energy efficiency, promoting renewable sources of energy, carbon dioxide capture and storage, limiting deforestation, afforestation or the prevention of accidents in the energy sector.

    Full Text Available Introduction In addition to the common alterations and diseases inherent in the aging process, elderly persons with a history of leprosy are particularly vulnerable to dependence because of disease-related impairments. Objective determine whether physical impairment from leprosy is associated with dependence among the elderly. Methods An analytical cross-sectional study of elderly individuals with a history of leprosy and no signs of cognitive impairment was conducted using a database from a former leprosy colony-hospital. The patients were evaluated for dependence in the basic activities of daily living (BADL and instrumental activities of daily living (IADL, respectively and subjected to standard leprosy physical disability grading. Subsequently, descriptive and univariate analyses were conducted, the latter using Pearson's chi-squared test. Results A total of 186 elderly persons were included in the study. Of these individuals, 53.8% were women, 49.5% were older than 75 years of age, 93% had four or less years of formal education, 24.2% lived in an institution for the long-term care of the elderly (ILTC, and 18.3% had lower limb amputations. Among those evaluated, 79.8% had visible physical impairments from leprosy (grade 2, 83.3% were independent in BADL, and 10.2% were independent in IADL. There was a higher impairment grade among those patients who were IADL dependent (p=0.038. Conclusion s: The leprosy physical impairment grade is associated with dependence for IADL, creating the need for greater social support and systematic monitoring by a multidisciplinary team. The results highlight the importance of early diagnosis and treatment of leprosy to prevent physical impairment and dependence in later years.

    2017-07-01

    Full Text Available Diagnostic criteria for complex medical conditions caused by a multitude of both genetic and environmental factors should be descriptive and avoid any attribution of causality. Furthermore, the wording used to describe a disorder should be evidence-based and avoid stigmatization of the affected individuals. Both terminology and categorizations should be readily comprehensible for healthcare professionals and guide clinical decision making. Uncertainties with respect to diagnostic issues and their implications may be addressed to direct future clinical research. In this context, the European Association of the Study of Obesity (EASO considers it an important endeavor to review the current ICD-11 Beta Draft for the definition of overweight and obesity and to propose a substantial revision. We aim to provide an overview of the key issues that we deem relevant for the discussion of the diagnostic criteria. We first discuss the current ICD-10 criteria and those proposed in the ICD 11 Beta Draft. We conclude with our own proposal for diagnostic criteria, which we believe will improve the assessment of patients with obesity in a clinically meaningful way.

  11. Mobile technology habits: patterns of association among device usage, intertemporal preference, impulse control, and reward sensitivity.

    Science.gov (United States)

    Wilmer, Henry H; Chein, Jason M

    2016-10-01

    Mobile electronic devices are playing an increasingly pervasive role in our daily activities. Yet, there has been very little empirical research investigating how mobile technology habits might relate to individual differences in cognition and affect. The research presented in this paper provides evidence that heavier investment in mobile devices is correlated with a relatively weaker tendency to delay gratification (as measured by a delay discounting task) and a greater inclination toward impulsive behavior (i.e., weaker impulse control, assessed behaviorally and through self-report) but is not related to individual differences in sensitivity to reward. Analyses further demonstrated that individual variation in impulse control mediates the relationship between mobile technology usage and delay of gratification. Although based on correlational results, these findings lend some backing to concerns that increased use of portable electronic devices could have negative impacts on impulse control and the ability to appropriately valuate delayed rewards.

    We present a generalization of the linear one-dimensional diffusion equation by combining the fractional derivatives and the internal degrees of freedom. The solutions are constructed from those of the scalar fractional diffusion equation. We analyze the interpolation between the standard diffusion and wave equations defined by the fractional derivatives. Our main result is that we can define a diffusion process depending on the internal degrees of freedom associated to the system.

    Full Text Available ObjectiveTo investigate the association of Model for End-Stage Liver Disease (MELD score with complications and early survival rate after liver transplantation for benign end-stage liver disease, and to analyze the criteria to select donor livers with fatty liver for patients with different MELD scores. MethodsA total of 145 recipients of orthotopic liver transplantation with benign end-stage liver disease in Fuzhou General Hospital of Nanjing Military Command from January 2008 to December 2013 were analyzed retrospectively, and frozen fatty liver biopsy was performed for donor livers in 47 patients before transplantation. The patients were divided into the following three groups according to MELD score: group A with 28 patients (MELD score ≥30, mean MELD score 35.7±5.5; group B with 35 patients (20≤ MELD score <30, mean MELD score 22.5±2.3; group C with 82 patients (MELD score <20, mean MELD score 11.0±3.7. The preoperative, intraoperative, and postoperative biochemical parameters, postoperative complications, and survival rate were compared between these groups. The 47 patients receiving frozen biopsy were divided into the following two groups according to MELD score: group a with 9 patients (MELD score ≥30; group b with 38 patients (MELD score <30. The 1-year survival rates of the recipients of donor livers with mild, moderate, and severe fatty liver were compared between the two groups. Comparison of continuous data between the two groups was made by t test or ANOVA and comparison of categorical date was made by chi-square test or Fisher’s exact. ResultsThe 1-month survival rate after transplantation showed no significant difference between groups A, B, and C (71.4%, 87.8%, and 86.6%, respectively; P>0.05; group A had significantly lower 3-month, 6-month, and 1-year survival rates than groups B and C (64.3%/64.3%/64.3% vs 88.6%/886%/88.6% and 87.8%/86.6%/86.6%, all P<0.05.

    This paper examines N-th degree stochastic dominance which isused to compare the risk factor of risky assets after summarizing the definitions of first degree stochastic dominance and second degree stochastic dominance. The paper defines general N-th degree stochastic dominance, presents a sufficient and necessary condition which is the equivalent theorem of general N-th degree stochastic dominance. The feasible utility form is constructed to explain the economic meaning of N-th degree stochastic dominance in the field of financial economics. The equivalent condition is described by the probability distribution functions of risky assets, which are not related to utility functions (preference relations).

    Animal telemetry, which requires the implantation of passive transponders or active transmitters, is used to monitor and assess fish stock and conservation to gain an understanding of fish movement and behavior. As new telemetry technologies become available, studies of their effects on species of interest are imperative as is development of implantation techniques. In this study, we investigated the effects of bevel rotation (0-, 90-, 180-degree axis rotation) on wound extent, tag loss, and wound healing rates in juvenile Chinook salmon injected with an 8-gauge needle, which is required for implantation of the novel injectable Juvenile Salmon Acoustic Telemetry Systems (JSATS) acoustic transmitter or large passive integrated transponder (PIT) tags. Although the injection sites were not closed after injection (e.g., with sutures or glue), there were no mortalities, dropped tags, or indications of fungus, ulceration, and/or redness around the wound. On Day 0 and post-implantation Day 7, the 90-degree bevel rotation produced smaller wound extent than the 180-degree bevel rotation. No axis rotation (0-degrees) resulted in the PIT tag frequently misleading or falling out upon injection. The results of this study indicated the 90-degree bevel rotation was the more efficient technique, produced less wound extent. Given the wound extent compared to size of fish, we recommend researchers should consider a 90-degree rotation over the 180-degree rotation in telemetry studies. Highlights •Three degrees of needle rotation were examined for effects in Chinook salmon. •Mortality, tag loss, wound extent, healing, and infection indicators were measured. •There were no mortalities, tag loss, or indications of infection. •The 90-degree needle rotation through Day 7 produced the smallest wound extent.

    The tar-sand resources of the US have the potential to yield as much as 36 billion barrels (bbls) of oil. The tar-sand petroleum-extraction technologies now being considered for commercialization in the United States include both surface (above ground) systems and in situ (underground) procedures. The surface systems currently receiving the most attention include: (1) thermal decomposition processes (retorting); (2) suspension methods (solvent extraction); and (3) washing techniques (water separation). Underground bitumen extraction techniques now being field tested are: (1) in situ combustion; and (2) in situ steam-injection procedures. At this time, any commercial tar-sand facility in the US will have to comply with at least 7 major federal regulations in addition to state regulations; building, electrical, and fire codes; and petroleum-industry construction standards. Pollution-control methods needed by tar-sand technologies to comply with regulatory standards and to protect air, land, and water quality will probably be similar to those already proposed for commercial oil-shale systems. The costs of these systems could range from about $1.20 to $2.45 per barrel of oil produced. Estimates of potential pollution-emisson levels affecting land, air, and water were calculated from available data related to current surface and in situ tar-sand field experiments in the US. These data were then extrapolated to determine pollutant levels expected from conceptual commercial surface and in situ facilities producing 20,000 bbl/d. The likelihood-of-occurrence of these impacts was then assessed. Experience from other industries, including information concerning health and ecosystem damage from air pollutants, measurements of ground-water transport of organic pollutants, and the effectiveness of environmental-control technologies was used to make this assessment.

    Timár, Gábor; Mendes, José Fernando F

    2016-01-01

    A majority of studied models for scale-free networks have degree distributions with exponents greater than $2$. Real networks, however, can demonstrate essentially more heavy-tailed degree distributions. We explore two models of scale-free equilibrium networks that have the degree distribution exponent $\\gamma = 1$, $P(q) \\sim q^{-\\gamma}$. Such "superfat-tailed" degree distributions can be identified in empirical data only if the mean degree of a network is sufficiently high. Our models exploit a rewiring mechanism. They are local in the sense that no knowledge of the network structure, apart from the immediate neighbourhood of the vertices, is required. These models generate uncorrelated networks in the infinite size limit, where they are solved explicitly. We investigate finite size effects by the use of simulations. We find that both models exhibit disassortative degree-degree correlations for finite network sizes. In addition, we observe a markedly degree-dependent clustering in the finite networks. We i...

  10. Are UK undergraduate Forensic Science degrees fit for purpose?

    Science.gov (United States)

    Welsh, Charles; Hannis, Marc

    2011-09-01

    In October 2009 Skills for Justice published the social research paper 'Fit for purpose?: Research into the provision of Forensic Science degree programmes in UK Higher Education Institutions.' The research engaged employers representing 95% of UK Forensic Science providers and 79% of UK universities offering Forensic Science or Crime Scene degree programmes. In addition to this, the research collected the views of 430 students studying these degrees. In 2008 there were approximately 9000 people working in the Forensic Science sector in the UK. The research found that the numbers of students studying Forensic Science or Crime Scene degrees in the UK have more than doubled since 2002-03, from 2191 in to 5664 in 2007-08. Over the same period there were twice as many females as males studying for these degrees. The research concluded that Forensic Science degree programmes offered by UK universities were of a good quality and they provided the student with a positive learning experience but the content was not relevant for Forensic Science employers. This echoed similar research by the former Government Department for Innovation, Universities and Skills on graduates from wider science, technology, engineering and mathematics degree programmes. The research also found that 75% of students studying Forensic Science or Crime Scene degrees expected to have a career in the Forensic Science sector, meaning that ensuring these courses are relevant for employers is a key challenge for universities. This paper reflects on the original research and discusses the implications in light of recent government policy. Copyright © 2011 Forensic Science Society. Published by Elsevier Ireland Ltd.

    2008-01-01

    Recent mobile equipment (as well as the norm IEEE 802.21) now offers the possibility for users to switch from one technology to another (vertical handover). This allows flexibility in resource assignments and, consequently, increases the potential throughput allocated to each user. In this paper, we design a fully distributed algorithm based on trial and error mechanisms that exploits the benefits of vertical handover by finding fair and efficient assignment schemes. On the one hand, mobiles gradually update the fraction of data packets they send to each network based on the rewards they receive from the stations. On the other hand, network stations send rewards to each mobile that represent the impact each mobile has on the cell throughput. This reward function is closely related to the concept of marginal cost in the pricing literature. Both the station and the mobile algorithms are simple enough to be implemented in current standard equipment. Based on tools from evolutionary games, potential games and rep...

    Integrated electronic prescribing systems (IEPSs) are expected to improve efficiency and safety in the management of pharmaceuticals throughout the healthcare sector. In Sweden (population 9 million), more than 25 million e-prescriptions each year are processed in the National IEPS. We set out to examine the introduction of an IEPS into pharmacists' practice with regard to impact on work efficiency and pharmacological safety. A questionnaire was distributed to all pharmacists (n = 74) in a Swedish municipality (population 145,000), where an IEPS had recently been introduced. The response rate was 70%. The IEPS was in general perceived to have expedited the processing of prescriptions and reduced the risk for prescription errors as well as the handing over of erroneous medications to patients. We found that there was a positive correlation between usefulness of the IEPS system for work efficacy and pharmacological safety, respectively (r =0 .524, p IEPS for work efficacy and perception of barriers to technology use (r = -0.010, p > 0.05). We also found that there was a negative correlation between IEPS usefulness for pharmacological safety and that barriers to IEPS technology use were experienced (r = 0.031, p > 0.05). The results indicate that reduction of system unavailability due to technical issues will increase the perceived usefulness of IEPSs for pharmacists with regard to both work efficacy and pharmacological safety. We conclude that the introduction of an IEPS was well received by pharmacists; however, barriers to full acceptance remained, in particular, system unavailability due to technical problems.

    Family communication is central to the family and its functioning. It is a mutual process in which family members create, share, and regulate meaning. Advancement and proliferation of information and communication technologies (ICTs) continues to change methods of family communication. However, little is known about the use of different methods for family communication and the influence on family well-being. We investigated the sociodemographic factors associated with different methods of family communication and how they are associated with perceived family harmony, happiness, and health (3Hs) among Chinese adults in Hong Kong. Data came from a territory-wide probability-based telephone survey using the Family and Health Information Trend survey (FHInTs). Frequency of family communication using different methods (ie, face-to-face, phone, instant messaging [IM], social media sites, and email) were recoded and classified as frequent (always/sometimes) and nonfrequent (seldom/never) use. Family well-being was measured using 3 questions of perceived family harmony, happiness, and health with higher scores indicating better family well-being. Adjusted odds ratios for family communication methods by sociodemographic characteristics and adjusted beta coefficients for family well-being by communication methods were calculated. A total of 1502 adults were surveyed. Face-to-face (94.85%, 1408/1484) was the most frequent means of communication followed by phone (78.08%, 796/1484), IM (53.64%, 796/1484), social media sites (17.60%, 261/1484), and email (13.39%, 198/1484). Younger age was associated with the use of phone, IM, and social media sites for family communication. Higher educational attainment was associated with more frequent use of all modes of communication, whereas higher family income was only significantly associated with more frequent use of IM and email (P=.001). Face-to-face (beta 0.65, 95% CI 0.33-0.97) and phone use (beta 0.20, 95% CI 0.02-0.38) for family

    Intelligence test scores and educational levels were compared for 5943 myopic and 9891 non-myopic 18-year-old men being drafted for military service in Denmark. The former were grouped by degree of myopia, in the range -0.25 diopters (D) to -7.75 D, according to the power of correcting lenses required. Myopes of all degrees had significantly higher test scores and educational levels than non-myopes. However, the relation of these two variables to degree of myopia was not linear; for both variables there were no significant differences among myopia groups in the range -2.0 to -7.75 D. Whereas factors associated with intelligence and education seem to be important in triggering the onset of myopia, they seem to be much less important in determining the degree to which myopia progresses.

    Objective: To investigate the effect of 360-degree retinectomy for severe ocular rupture and evaluate the related factors associated with prognosis.Methods: A retrospective analysis was performed on 28 consecutive patients, 18 men and 10 women, with severe ocular rupture admitted to the Chinese PLA General Hospital between January 1999 and January 2002. The patients' ages ranged from 16 to 58 years, mean 29.5years. All operations were performed by the first author.All patients underwent standard 3-port pars plana vitrectomy with scleral encircling buckle,endophotocoagulation, and tamponaded with silicone oil.Lensectomy were performed on 15 eyes. 360-degree retinotomy and retinectomy were performed at anterior equator on 16 eyes, and posterior equator on 12 eyes.Results: During operation, all patients were confirmed to have vitreous hemorrhage and retinal detachment, in which hemorrhagic ciliary body detachment was found in 9 eyes, suprachoroidal hemorrhage in 12 eyes,retinal twisting like flower stalk in 11 eyes, and retinal incarceration in 17 eyes. Postoperative follow-up was conducted in 26 cases, ranged from 6 months to 46 months.Retinal reattachment achieved in 20 eyes (76. 9%), in which three patients' retina was reattached after revitrectomy. The silicone oil was removed at the fourth month in 8 eyes postoperatively. Corrected visual acuity of 0.02 or more was in 14 eyes (70. 0%) among the 20patients with reattached retina. Visual acuity of 0.05 or more was in 7 eyes ( 35.0 % ), and 0.1 or more was in 3eyes. The best visual acuity was 0.3 in 1 eye.Conclusions: Retinectomy may improve the prognosis of severe ocular rupture and save the visual function of some patients.

    1997-01-01

    This is a sub-section of the 'geometrically improved, color enhanced' version of the 360-degree panorama heretofore known as the 'Gallery Pan', the first contiguous, uniform panorama taken by the Imager for Mars Pathfinder (IMP) over the course of Sols 8, 9, and 10. Different regions were imaged at different times over the three Martian days to acquire consistent lighting and shadow conditions for all areas of the panorama.The IMP is a stereo imaging system that, in its fully deployed configuration, stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. In this geometrically improved version of the panorama, distortion due to a 2.5 degree tilt in the IMP camera mast has been removed, effectively flattening the horizon.The IMP has color capability provided by 24 selectable filters -- twelve filters per 'eye'. Its red, green, and blue filters were used to take this image. The color was digitally balanced according to the color transmittance capability of a high-resolution TV at the Jet Propulsion Laboratory (JPL), and is dependent on that device. In this color enhanced version of the panorama, detail in surface features are brought out via changes to saturation and intensity, holding the original hue constant. A threshold was applied to avoid changes to the sky.At left is a Lander petal and a metallic mast which is a portion of the low-gain antenna. Misregistration in the antenna and other Lander features is due to parallax in the extreme foreground. Another Lander petal is at the right, showing the fully deployed forward ramp.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C.

    2002-08-01

    The focus of this study is on a 'top-level' examination of the sustainability of nuclear energy in the context of the overall nuclear fuel cycle (NFC). This evaluation is conducted according to a set of established sustainability criteria that encompasses key economic (energy generation costs), environmental (resource utilization, long-term waste accumulations), and societal (nuclear-weapons proliferation risk) concerns associated with present and future NFC approaches. In this study, key NFCs are assessed according to a simplified and limited set of criteria that attempts to quantify NFC concerns related to cost, resource, waste, and proliferation. The overarching aim of this study is to examine a representative set of NFC options on a relative basis according to the adopted set of criteria to aid in the assessment and decision-making process. These criteria were then aggregated into a single, composite metric to examine the impacts of specific 'stakeholder' preferences. The study architecture is based on sets of nuclear process components. These sets are assembled around a particular nuclear reactor technology for the generation of electricity. Selections are made from the resulting sets of reactor-centric technologies and grouped to form nine central NFC scenarios. The above-described sustainability metrics are evaluated using a steady-state (equilibrium), highly aggregated model that is applied through mass and energy conservation to evaluate each NFC scenario. Six NFC scenarios examined to varying degrees are adaptations or extensions of scenarios used in a recent OECD study (OECD, 2002) of partitioning and transmutation (P and T) schemes based on accelerator-driven systems (ADS) or fast reactors (FR). Three NFC scenarios are based entirely on present-day or near-term LWR technologies. In addition to these near-term scenarios, more advanced systems considered in the original OECD study on which this model is based were retained using a

    Full Text Available Bovine viral diarrhea virus (BVDV is a common pathogen that causes major economic losses to dairyindustry worldwide. Amplification of 5’-UTR regions of BVDV genome from blood samples usingreversetranscriptase polymerase chain reaction (RT-PCR is one of sensitive and accurate techniques forBVDV detection. A common limitation for molecular detection of virus is the ability to obtain high qualityof nucleic acid in the samples. Inappropriate storage conditions will result in a false negative test. FiveEDTA-blood samples collected from BVDV persistently infected cattle were used in the present study.Ten repetitions were done for each sample. The blood were then dripped in the middle part of the FlindersTechnology AssociatesTM (FTA cards and let it dried for approximately 2 hours. The effectiveness of theFTATMcards for storage and retrieval of BVDV RNA from blood samples molecularly using RT-PCRtechnique were tested and evaluated. The results proved that FTATM cards are effective and safe for thestorage of BVDV genome for a long period at room temperature. Based on the result of the present study,it can be concluded that in veterinary medicine field, the application of FTATM technology needs to bedeveloped to various type of samples and should be used routinely for collecting samples containinginfectious agents.

    This study analyzed aircraft incidents in the NASA Aviation Safety Reporting System (ASRS) that apply to two of the three technical challenges (TCs) in NASA's Aviation Safety Program's Atmospheric Environment Safety Technology Project. The aircraft incidents are related to airframe icing and atmospheric hazards TCs. The study reviewed incidents that listed their primary problem as weather or environment-nonweather between 1994 and 2011 for aircraft defined by Federal Aviation Regulations (FAR) Parts 121, 135, and 91. The study investigated the phases of flight, a variety of anomalies, flight conditions, and incidents by FAR part, along with other categories. The first part of the analysis focused on airframe-icing-related incidents and found 275 incidents out of 3526 weather-related incidents over the 18-yr period. The second portion of the study focused on atmospheric hazards and found 4647 incidents over the same time period. Atmospheric hazards-related incidents included a range of conditions from clear air turbulence and wake vortex, to controlled flight toward terrain, ground encounters, and incursions.

    2009-12-01

    Over his entire career, Gerald Epstein has toiled at the nexus of science, technology, and security. From 2003 to 2009, he was Senior Fellow for Science and Security at the Center for Strategic and International Studies Homeland Security Program, where he worked on reducing biological weapons threats, improving national preparedness, and easing potential tensions between the scientific research and national security communities. Epstein came to CSIS from the Institute for Defense Analyses. From 1996 to 2001, he served in the White House Office of Science and Technology Policy. And from 1983 to 1989, and again from 1991 until its demise in 1995, Epstein worked at the Congressional Office of Technology Assessment, where he directed a study on the proliferation of weapons of mass destruction, alongside research on other global security topics. A recognized expert in biological risk reduction, Epstein was actually trained as a physicist, having received SB degrees in physics and electrical engineering from MIT, and a PhD in physics from the University of California at Berkeley. How, then, did he come to study the evolving threat from bioterrorism? "What compelled me about bioterrorism was that it was a stellar example of a topic that would lead to a train wreck between the scientific community and the security community unless they figured out how to work together," he said. "The distance between a laboratory and a very large consequence event is a lot shorter in biology than in any other field. I got into bioterrorism to help make sure that the security community doesn't get so scared of the science that it shuts it down, and that the science community isn't so oblivious of security concerns that it pays no attention to them." Epstein spoke on November 6, 2009, with contributing writer Madeline Drexler, author of Emerging Epidemics: The Menace of New Infections (Penguin, 2009), an updated version of an earlier volume. Drexler holds a visiting appointment at the

    asignatura. Cuáles han sido los aspectos que ha mejorado y cuáles son los que se podrían mejorar. Abstract Many studies indicate that the need for professionals with BIM skills is undergoing a fast growth. This growth is giving rise to problems in the implementation of BIM in the sector: the main one is the lack of training of technicians in this area. The current university education is based on the acquisition of skills by students. In line with the requirements of the European Higher Education Area which calls competencies the skills to be acquired by the student. In this paper, the teaching experience of the implementation of BIM technology in the project subject is going to be explained. This subject is compulsory for the three disciplines of the Industrial Engineering Degree. The objective is to deduce if the teaching use of the BIM technology facilitates the acquisition of knowledge and improves the understanding of the subject. BIM education should focus on the development of basic knowledge, skills and attitudes of students. In addition, it is necessary to emphasize the need for construction industry technicians to have skills such as collaboration, communication, leadership and change management, along with technical skills related to BIM. The academic world plays an important role in transforming the industry driven by BIM. While government agencies and the private sector use BIM for new construction, university programs have been much slower in incorporating this technology. Universities are staying behind the construction industry in terms of adopting BIM technology in student training. Actually, the benefits and difficulties that has meant the implementation of BIM technology in the development of the subject is evaluated in this work: which aspects have improved and which aspects could be improved.

    This 360-degree panorama was taken in stereo by the deployed Imager for Mars Pathfinder (IMP) on Sol 3. 3D glasses (red left lens, blue right lens) are necessary to help identify surface detail. All three petals, the perimeter of the deflated airbags, deployed rover Sojourner, forward and backward ramps and prominent surface features are visible, including the double Twin Peaks at the horizon. Sojourner would later investigate the rock Barnacle Bill just to its left in this image, and the larger rock Yogi at its forward right.The IMP is a stereo imaging system with color capability provided by 24 selectable filters -- twelve filters per 'eye.' It stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. Stereoscopic imaging brings exceptional clarity and depth to many of the features in this image, particularly the ridge beyond the far left petal and the large rock Yogi. The curvature and misalignment of several section are due to image parallax.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

  16. The association between tolerance for ambiguity and fear of negative evaluation: A study of engineering technology capstone courses

    Science.gov (United States)

    Dubikovsky, Sergey I.

    For many students in engineering and engineering technology programs in the US, senior capstone design courses require students to form a team, define a problem, and find a feasible technical solution to address this problem. Students must integrate the knowledge and skills acquired during their studies at the college or university level. These truly integrative design activities do not have a single "correct" solution. Instead, there is an array of solutions, many of which could be used to achieve the final result. This ambiguity can cause students to experience anxiety during the projects. This study examined the main topics: • To what extent is a social anxiety (measured as fear of negative evaluation) related to tolerance for ambiguity in senior engineering capstone courses? • How does exposure to ambiguity prior to and during capstone courses affect tolerance for ambiguity? The study looked at the standard educational practices to see if they have unintended consequences, such a social anxiety in dealing with ambiguity. Those consequences are highly undesirable because they reduce students' learning. It was hypothesized that the lecture-based approaches that are more common in the first three years of study would not prepare students for self-directed capstone courses because the students would rarely have experienced problem-based learning before. The study used a quantitative approach and examined students' perceptions of their tolerance for ambiguity, and social anxiety before and after their senior capstone design experience. A survey instrument was adapted to measure exposure to ambiguity, which was studied as a potential moderator of the relationship between social anxiety and tolerance for ambiguity. The study indicated that social anxiety, as measured by fear of negative evaluation, does not play a major role in capstone courses. The second finding is that a single course, even if it was administered as a problem-based senior class, failed to

  17. Degree-layer theory of network topology

    CERN Document Server

    Zhou, Bin; Zhe, He

    2014-01-01

    The network topology can be described by the number of nodes and the interconnections among them. The degree of a node in a network is the number of connections it has to other nodes and the degree distribution is the probability distribution of these degrees over the whole network. Therefore, the degree is very important structural parameter of network topology. However, given the number of nodes and the degree of each node in a network, the topology of the network cannot be determined. Therefore, we propose the degree-layer theory of network topology to describe deeply the network topology. First, we propose the concept of degree-tree with the breadth-first search tree. The degrees of all nodes are layered and have a hierarchical structure. Second,the degree-layer theory is described in detail. Two new concepts are defined in the theory. An index is proposed to quantitatively distinguish the two network topologies. It also can quantitatively measure the stability of network topology built by a model mechani...

When degree-degree correlations are not present, the standardized variance of the network's degree distribution has been shown to be an accurate analytical measure of network heterogeneity that can be used to predict the success of cooperation. In this paper, we use a local-mechanism interpretation of standardized variance to give a generalization to graphs with degree-degree correlations. Two distinct mechanisms are shown to influence cooperation levels on these types of networks. The first is an intrinsic measurement of base-line heterogeneity coming from the network's degree distribution. The second is the increase in heterogeneity coming from the degree-degree correlations present in the network. A strong linear relationship is found between these two parameters and the average cooperation level in an evolutionary prisoner's dilemma on a network.

    The use of information and communication technology (ICT) is common in modern working life. ICT demands may give rise to experience of work-related stress. Knowledge about ICT demands in relation to other types of work-related stress and to self-rated health is limited. Consequently, the aim of this study was to examine the association between ICT demands and two types of work-related stress [job strain and effort-reward imbalance (ERI)] and to evaluate the association between these work-related stress measures and self-rated health, in general and in different SES strata. This study is based on cross-sectional data from the Swedish Longitudinal Occupational Survey of Health collected in 2014, from 14,873 gainfully employed people. ICT demands, job strain, ERI and self-rated health were analysed as the main measures. Sex, age, SES, lifestyle factors and BMI were used as covariates. ICT demands correlated significantly with the dimensions of the job strain and ERI models, especially with the demands (r = 0.42; p < 0.01) and effort (r = 0.51; p < 0.01) dimensions. ICT demands were associated with suboptimal self-rated health, also after adjustment for age, sex, SES, lifestyle and BMI (OR 1.49 [95 % CI 1.36-1.63]), but job strain (OR 1.93 [95 % CI 1.74-2.14) and ERI (OR 2.15 [95 % CI 1.95-2.35]) showed somewhat stronger associations with suboptimal self-rated health. ICT demands are common among people with intermediate and high SES and associated with job strain, ERI and suboptimal self-rated health. ICT demands should thus be acknowledged as a potential stressor of work-related stress in modern working life.

    Anti-idiotypic MK2-23 monoclonal antibody (anti-Id MK2-23 mAb), which mimics the high molecular weight melanoma-associated antigen (HMW-MAA), has been used to implement active immunotherapy against melanoma. However, due to safety and standardization issues, this approach never entered extensive clinical trials. In the present study, we investigated the usage of DNA vaccines as an alternative to MK2-23 mAb immunization. MK2-23 DNA plasmids coding for single chain (scFv) MK2-23 antibody were constructed via the insertion of variable heavy (V H) and light (V L) chains of MK2-23 into the pVAC-1mcs plasmids. Two alternative MK2-23 plasmids format V H/V L, and V L/V H were assembled. We demonstrate that both polypeptides expressed by scFv plasmids in vitro retained the ability to mimic HMW-MAA antigen, and to elicit specific anti-HMW-MAA humoral and cellular immunoresponses in immunized mice. Notably, MK2-23 scFv DNA vaccines impaired the onset and growth of transplantable B16 melanoma cells not engineered to express HMW-MAA. This pilot study suggests that optimized MK2-23 scFv DNA vaccines could potentially provide a safer and cost-effective alternative to anti-Id antibody immunization, for melanoma immunotherapy.

    The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case-control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10-24 years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure and brain tumor risk in young people in a large number of countries is complex and poses methodological challenges. This manuscript discusses the design of MOBI-Kids and describes the challenges and approaches chosen to address them, including: (1) the choice of controls operated for suspected appendicitis, to reduce potential selection bias related to low response rates among population controls; (2) investigating a young study population spanning a relatively wide age range; (3) conducting a large, multinational epidemiological study, while adhering to increasingly stricter ethics requirements; (4) investigating a rare and potentially fatal disease; and (5) assessing exposure to EMF from communication technologies. Our experience in thus far developing and implementing the study protocol indicates that MOBI-Kids is feasible and will generate results that will contribute to the understanding of potential brain tumor risks associated with use of mobile phones and other wireless communications technologies among young people.

    2014-01-01

    In stochastic block models, which are among the most prominent statistical models for cluster analysis of complex networks, clusters are defined as groups of nodes with statistically similar link probabilities within and between groups. A recent extension by Karrer and Newman [Karrer and Newman......, Phys. Rev. E 83, 016107 (2011)] incorporates a node degree correction to model degree heterogeneity within each group. Although this demonstrably leads to better performance on several networks, it is not obvious whether modeling node degree is always appropriate or necessary. We formulate the degree...... corrected stochastic block model as a nonparametric Bayesian model, incorporating a parameter to control the amount of degree correction that can then be inferred from data. Additionally, our formulation yields principled ways of inferring the number of groups as well as predicting missing links...

    Given a vertex v of a graph G the second order degree of v denoted as d2 (v) is defined as the number of vertices at distance 2 from v.In this paper we address the following question:What are the sufficient conditions for a graph to have a vertex v such that d2(v) ≥ d(v),where d(v) denotes the degree of v? Among other results,every graph of minimum degree exactly 2,except four graphs,is shown to have a vertex of second order degree as large as its own degree.Moreover,every K-4-free graph or every maximal planar graph is shown to have a vertex v such that d2(v) ≥ d(v).Other sufficient conditions on graphs for guaranteeing this property are also proved.

    Full Text Available Canadian university students tend to endorse employment-related reasons for attending university ahead of other reasons such as personal satisfaction or intellectual growth. In the present study, first- and fourth-year students from a mid-sized Canadian university reported on the benefits they expected to receive from their degree and rated their relative importance. These open-ended responses suggested that both groups of students placed a greater emphasis on benefits related to career preparation and economic advancement than those associated with learning and self-improvement. However, when asked to evaluate the importance of a comprehensive list of degree-related benefits both groups of students endorsed the value of many of them, including those related to learning and self-improvement. Our results suggest the importance of methodology in gathering data about this issue, and we consider them in light of current concerns with helping students to understand the full value of their degree. Les étudiants des universités canadiennes ont tendance à accepter les raisons qui se rapportent à l’emploi pour justifier les études universitaires avant d’autres raisons telles que la satisfaction personnelle ou la croissance intellectuelle.

In this context, ICTs should become teaching tools in order to help the teacher to achieve quality education.Being aware of the importance of the teachers' mastery of the digital skills, we have conducted a study about the mastery of the ICTs that the students in the third year of the degree of teacher training of the University of Vigo have. In order to do this we have taken into account the knowledge acquired, the frequency of use of certain tools, their level of proficiency in four areas of knowledge: technological literacy, intellectual working tools, processing and dissemination of information and as communication tools. As well as their motivations, interests and obstacles found in their development in order to develop proposals for initial training.We can conclude that, in general, students do not have a specific training on the use of computers. About the degree of knowledge in the different skills, the students know the most basic and commonly used (open or download a file, create or print a document, install a program or send an e-mail. They usually use the mail as a working tool, while the messaging and social networks are more used for leisure time.Their attitudes towards ICTs are very positive and their motivations are focused essentially on the technologies which are useful for improving their learning and for their professional future.

    Managers work to achieve the greatest output for the least input effort, better balancing all factors of delivery to achieve the most with the smallest resource effort. Documentation of actual health information technology (HIT) cost savings has been elusive. Information technology and linear programming help to control hospital costs without harming service quality or staff morale. This study presents production function results from a study of hospital output during the period 2008-2011. The results suggest that productivity varies widely among the 58 hospitals as a function of staffing patterns, methods of organization, and the degree of reliance on information support systems. Financial incentives help to enhance productivity. Incentive pay for staff based on actual productivity gains is associated with improved productivity. HIT can enhance the marginal value product of nurses and staff, so that they concentrate their workday around patient care activities. The implementation of electronic health records (EHR) was associated with a 1.6 percent improvement in productivity.

    2011-01-01

    For a finitely generated algebra over a field, the transcendence degree is known to be equal to the Krull dimension. The aim of this paper is to generalize this result to algebras over rings. A new definition of the transcendence degree of an algebra A over a ring R is given by calling elements of A algebraically dependent if they satisfy an algebraic equation over R whose trailing coefficient, with respect to some monomial ordering, is 1. The main result is that for a finitely generated algebra over a Noetherian Jacobson ring, the transcendence degree is equal to the Krull dimension.

    Debarre, O

    1992-01-01

    The degree of a curve $C$ in a polarized abelian variety $(X,\\lambda)$ is the integer $d=C\\cdot\\lambda$. When $C$ generates $X$, we find a lower bound on $d$ which depends on $n$ and the degree of the polarization $\\lambda$. The smallest possible degree is $d=n$ and is obtained only for a smooth curve in its Jacobian with its principal polarization (Ran, Collino). The cases $d=n+1$ and $d=n+2$ are studied. Moreover, when $X$ is simple, it is shown, using results of Smyth on the trace of totally positive algebraic integers, that if $d\\le 1.7719\\, n$, then $C$ is smooth and $X$ is isomorphic to its Jacobian. We also get an upper bound on the geometric genus of $C$ in terms of its degree.

  6. Rotation-Enabled 7-Degree of Freedom Seismometer for Geothermal Resource Development. Phase 1 Final Report

    Pierson, Bob [Applied Technology Associates, Albuquerque, NM (United States); Laughlin, Darren [Applied Technology Associates, Albuquerque, NM (United States)

    2013-10-29

    Under this Department of Energy (DOE) grant, A-Tech Corporation d.b.a. Applied Technology Associates (ATA), seeks to develop a seven-degree-of-freedom (7-DOF) seismic measurement tool for high-temperature geothermal applications. The Rotational-Enabled 7-DOF Seismometer includes a conventional tri-axial accelerometer, a conventional pressure sensor or hydrophone, and a tri-axial rotational sensor. The rotational sensing capability is novel, based upon ATA's innovative research in rotational sensing technologies. The geothermal industry requires tools for high-precision seismic monitoring of crack formation associated with Enhanced Geothermal System (EGS) stimulation activity. Currently, microseismic monitoring is conducted by deploying many seismic tools at different depth levels along a 'string' within drilled observation wells. Costs per string can be hundreds of thousands of dollars. Processing data from the spatial arrays of linear seismometers allows back-projection of seismic wave states. In contrast, a Rotational-Enabled 7-DOF Seismometer would simultaneously measure p-wave velocity, s-wave velocity, and incident seismic wave direction all from a single point measurement. In addition, the Rotational-Enabled 7-DOF Seismometer will, by its nature, separate p- and s-waves into different data streams, simplifying signal processing and facilitating analysis of seismic source signatures and geological characterization. By adding measurements of three additional degrees-of-freedom at each level and leveraging the information from this new seismic observable, it is likely that an equally accurate picture of subsurface seismic activity could be garnered with fewer levels per hole. The key cost savings would come from better siting of the well due to increased information content and a decrease in the number of confirmation wells drilled, also due to the increase in information per well. Improved seismic tools may also increase knowledge, understanding

    A total of 78 patients (143 eyes) with low, medium and high degree myopia were assessed. Apart from standard ophthalmological tests, flowmetry and duplex ultrasound of ocular vessels were performed in all cases to evaluate volumetric and velocity parameters of ocular blood flow in relation to the length of anterior-posterior axis and the degree of myopia. It is found that both parameters of regional blood flow progressively decrease as the anterior-posterior axis increases.

Here we recommend a method and consider it a more suitable way for bacteria identification, that is, to first determine its genus by 16S rRNA, then determine its species as well as its subtypes using one or more genes that are more polymorphic. DNA barcoding technology can be used to improve the efficiency of pathogen detection and to speed up the standardization process, especially when for detecting quarantine pathogens. Thus it’s a powerful complement for conventional detection techniques.%植物病原细菌是植物病原菌的重要组成部分,DNA 条形码技术在植物病原细菌的鉴定中应用非常普遍,本文综述了在植物病原细菌鉴定中常用的基因及目前应用的一些数据库,认为在细菌鉴定中比较适用的方法为先通过16S rRNA 基因分析确定到属,然后通过多态性更强的基因或多个基因的联合应用鉴定到种或种下阶元。DNA 条形码技术可以作为常规检测技术的一个强有力补充,提高病原菌鉴定的标准化与速度,尤其对检疫性病原细菌的鉴定具有重要作用。

  11. Interplay of degree correlations and cluster synchronization

    2016-12-01

    We study the evolution of coupled chaotic dynamics on networks and investigate the role of degree-degree correlation in the networks' cluster synchronizability. We find that an increase in the disassortativity can lead to an increase or a decrease in the cluster synchronizability depending on the degree distribution and average connectivity of the network. Networks with heterogeneous degree distribution exhibit significant changes in cluster synchronizability as well as in the phenomena behind cluster synchronization as compared to those of homogeneous networks. Interestingly, cluster synchronizability of a network may be very different from global synchronizability due to the presence of the driven phenomenon behind the cluster formation. Furthermore, we show how degeneracy at the zero eigenvalues provides an understanding of the occurrence of the driven phenomenon behind the synchronization in disassortative networks. The results demonstrate the importance of degree-degree correlations in determining cluster synchronization behavior of complex networks and hence have potential applications in understanding and predicting dynamical behavior of complex systems ranging from brain to social systems.

    2013-01-01

    Many complex networks demonstrate a phenomenon of striking degree correlations, i.e., a node tends to link to other nodes with similar (or dissimilar) degrees. From the perspective of degree correlations, this paper attempts to characterize topological structures of urban street networks. We adopted six urban street networks (three European and three North American), and converted them into network topologies in which nodes and edges respectively represent individual streets and street intersections, and compared the network topologies to three reference network topologies (biological, technological, and social). The urban street network topologies (with the exception of Manhattan) showed a consistent pattern that distinctly differs from the three reference networks. The topologies of urban street networks lack striking degree correlations in general. Through reshuffling the network topologies towards for example maximum or minimum degree correlations while retaining the initial degree distributions, we found...

    In this study, we assessed the community and educational needs for sleep technologists by surveying program directors of nationally accredited polysomnography, electroneurodiagnostic technology, and respiratory care educational programs. Currently, little is known about our educational capacity and the need for advanced degrees for sleep medicine technical support. A questionnaire was developed about current and future community and educational needs for sleep technologists. The questionnaire was sent to directors of CAAHEP-accredited polysomnography and electroneurodiagnostic technology programs (associate degree and certificate programs), and directors of CoARC-accredited respiratory therapy associate degree and bachelor degree programs (n = 358). Qualitative and quantitative data were collected via an internet survey tool. Data analysis was conducted with the IBM SPSS statistical package and included calculating means and standard deviations of the frequency of responses. Qualitative data was analyzed and classified based on emerging themes. One hundred seven of 408 program directors completed the survey. Seventy-four percent agreed that demand for qualified sleep technologists will increase, yet 50% of those surveyed believe there are not enough educational programs to meet the demand. Seventy-eight percent of those surveyed agreed that the educational requirements for sleep technologists will soon increase; 79% of those surveyed believe sleep centers have a need for technologists with advanced training or specialization. Our study shows educators of associate and certificate degree programs believe there is a need for a bachelor's degree in sleep science and technology.

    2016-12-01

    For more that 20 years, the Global Learning and Observations to Benefit the Environment (GLOBE) Program has sought to increase environment literacy in students by involving them in the process of data collection and scientific research. In 2016, the program expanded to accept observations from citizen scientists of all ages through a relatively simple app. Called GLOBE Observer, the new program aims to help participants feel connected to a global community focused on advancing the scientific understanding of Earth system science while building climate literacy among participants and increasing valuable environmental data points to expand both student and scientific research. In October 2016, GLOBE Observer partnered with the Association of Science & Technology Centers (ASTC) in an international science experiment in which museums and patrons around the world collected cloud observations through GLOBE Observer to create a global cloud map in support of NASA satellite science. The experiment was an element of the International Science Center and Science Museum Day, an event planned in partnership with UNESCO and ASTC. Museums and science centers provided the climate context for the observations, while GLOBE Observer offered a uniform experience and a digital platform to build a connected global community. This talk will introduce GLOBE Observer and will present the results of the experiment, including evaluation feedback on gains in climate literacy through the event.

    2007-01-01

    The processing of amang, or tin tailings, for valuable minerals has been shown to technologically enhance NORM and this has stirred significant radiological safety and health concerns among Malaysia's regulatory authority. A growing radiological concern is now focused on the amang effluent containing NORM in recycling ponds, since these ponds may be reclaimed for future residential developments. A study was carried out to assess the radiological risk associated with amang processing and the accumulated effluent in the recycling ponds. Twenty-six sediment samples from the recycling ponds of two amang plants in the states of Selangor and Perak, Malaysia, were collected and analyzed. The maximum activity concentrations of (238)U, (226)Ra, (232)Th and (40)K recorded in sediments from these ponds were higher than Malaysia's and the world's natural highest. Correspondingly, the mean radium equivalent activity concentration indices, Ra(eq), and gamma radiation representative level index, I(gammar), were higher than the world's average. The enhancement of NORM in effluent sediments as a consequence of amang processing, and the use of a closed water management recycling system created Effective Dose Rates, E (nSv h(-1)), that signal potential environmental radiological risks in these ponds, should they be reclaimed for future land use.

  3. Decoherence of rotational degrees of freedom

    Zhong, Changchun; Robicheaux, F.

    2016-11-01

    The mechanism of decoherence for a mesoscopic quantum system with rotational degrees of freedom is studied. From a simple model of elastic scattering, we show that the nondiagonal density-matrix elements of the system exponentially decay. The decay rate depends on the difference of scattering amplitudes for different rotational configurations, leading to the gradual loss of quantum coherence between the pointer states in the orientational space. For a dielectric ellipsoid immersed in a photon-gas environment (assuming no absorption), the decay rate is found to be proportional to the seventh power of the temperature. For an ellipsoidal object interacting with massive particles, the decay rate is proportional to the 5/2 power of the temperature. Both are different from the case of translational decoherence induced by the same environment scattering. For photon scattering, the coherence time in the rotational degrees of freedom is shown to be much shorter than that in the translational degrees of freedom.

  4. Node degree distribution in spanning trees

    Pozrikidis, C.

    2016-03-01

    A method is presented for computing the number of spanning trees involving one link or a specified group of links, and excluding another link or a specified group of links, in a network described by a simple graph in terms of derivatives of the spanning-tree generating function defined with respect to the eigenvalues of the Kirchhoff (weighted Laplacian) matrix. The method is applied to deduce the node degree distribution in a complete or randomized set of spanning trees of an arbitrary network. An important feature of the proposed method is that the explicit construction of spanning trees is not required. It is shown that the node degree distribution in the spanning trees of the complete network is described by the binomial distribution. Numerical results are presented for the node degree distribution in square, triangular, and honeycomb lattices.

    This project aims to investigate the feasibility of a 360 degree feedback systems for KINS and to design guiding rules and structures in implementing that systems. Literature survey, environmental analysis and questionnaire survey were made to ensure that 360 degree feedback is the right tool to improve performance in KINS. That review leads to conclusion that more readiness and careful feasibility review are needed before implementation of 360 degree feedback in KINS. Further the project suggests some guiding rules that can be helpful for successful implementation of that system in KINS. Those include : start with development, experiment with one department, tie it to a clear organization's goal, train everyone involve, make sure to try that system in an atmosphere of trust.

  6. Social issues in nanoscience and nanotechnology master's degrees: the socio-political stakes of curricular choices

    Science.gov (United States)

    Fages, Volny; Albe, Virginie

    2015-06-01

    This paper proposes a study of the various ways in which social and ethical issues are integrated in the curricula of nanoscience and nanotechnology master degrees. During the last decade, new types of courses have appeared in science and technology universities, first in the United States and now reaching Europe and France, associating a call for interdisciplinarity with a strong convergence of science and industry and new ways of integrating social and/or human sciences in scientific curricula. These courses entitled "science and society", meant for science students, lean on (and participate in the construction of) specific ways of describing science, technology, and the social world, generally saturated with political values. The integration of these courses in science education, linked with a strong effort to specify new institutional organizations of scientific practice and education (in particular through political support of emerging fields like nanoscience, synthetic biology, or the cognitive sciences), may play an important role in the acculturation of future scientists and engineers to "good" scientific practices and discourses. The case of nanoscience and nanotechnology is particularly revealing of the changes which are now taking place in some universities. This paper will strive to identify different types of courses called "nano and society", taking examples from both French and American contexts, and linking them to more or less implicit socio-epistemic and political values.

  7. The Low-Degree Shape of Mercury

    2015-12-01

    The shape of Mercury, particularly when combined with its geoid, provides clues to the planet's internal structure, thermal evolution, and rotational history. Twenty-five million elevation measurements of the northern hemisphere, acquired by the Mercury Laser Altimeter on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, were combined with 378 occultation measurements of radio-frequency signals from the spacecraft in the planet's southern hemisphere to reveal the low-degree shape of Mercury. We solved for the spherical-harmonic coefficients through degree and order 128 and found that Mercury's mean radius is 2439.36±0.02 km. The offset between the planet's centers of mass and figure is negligible (40±40 m) along the polar axis and modest (140±50 m) in the equatorial plane. Mercury's spherical-harmonic shape spectrum is dominated by degree 2, and the planet's first-order shape is that of a triaxial ellipsoid with semimajor axes a, b, and c. The polar radius, c, is 1.65 km less than (a+b)/2, and the equatorial difference, a-b, is 1.25 km. The long axis is rotated 15° west of Mercury's dynamically defined principal axis. Mercury's geoid is similarly dominated by degree 2 and well described by a triaxial ellipsoid. The degree-2 geoid and shape are highly correlated, but the power spectral density of the geoid at degree 2 is only 1% of its shape counterpart, implying substantial compensation of elevation variations on a global scale and that Mercury is not in hydrostatic equilibrium.

  8. High-Degree Neurons Feed Cortical Computations.

    Nicholas M Timme

    2016-05-01

    Full Text Available Recent work has shown that functional connectivity among cortical neurons is highly varied, with a small percentage of neurons having many more connections than others. Also, recent theoretical developments now make it possible to quantify how neurons modify information from the connections they receive. Therefore, it is now possible to investigate how information modification, or computation, depends on the number of connections a neuron receives (in-degree or sends out (out-degree. To do this, we recorded the simultaneous spiking activity of hundreds of neurons in cortico-hippocampal slice cultures using a high-density 512-electrode array. This preparation and recording method combination produced large numbers of neurons recorded at temporal and spatial resolutions that are not currently available in any in vivo recording system. We utilized transfer entropy (a well-established method for detecting linear and nonlinear interactions in time series and the partial information decomposition (a powerful, recently developed tool for dissecting multivariate information processing into distinct parts to quantify computation between neurons where information flows converged. We found that computations did not occur equally in all neurons throughout the networks. Surprisingly, neurons that computed large amounts of information tended to receive connections from high out-degree neurons. However, the in-degree of a neuron was not related to the amount of information it computed. To gain insight into these findings, we developed a simple feedforward network model. We found that a degree-modified Hebbian wiring rule best reproduced the pattern of computation and degree correlation results seen in the real data. Interestingly, this rule also maximized signal propagation in the presence of network-wide correlations, suggesting a mechanism by which cortex could deal with common random background input. These are the first results to show that the extent to

  11. A network with tunable clustering, degree correlation and degree distribution, and an epidemic thereon

    CERN Document Server

    Ball, Frank; Sirl, David

    2012-01-01

    A random network model which allows for tunable, quite general forms of clustering, degree correlation and degree distribution is defined. The model is an extension of the configuration model, in which stubs (half-edges) are paired to form a network. Clustering is obtained by forming small completely connected subgroups, and positive (negative) degree correlation is obtained by connecting a fraction of the stubs with stubs of similar (dissimilar) degree. An SIR (Susceptible -> Infective -> Recovered) epidemic model is defined on this network. Asymptotic properties of both the network and the epidemic, as the population size tends to infinity, are derived: the degree distribution, degree correlation and clustering coefficient, as well as a reproduction number $R_*$, the probability of a major outbreak and the relative size of such an outbreak. The theory is illustrated by Monte Carlo simulations and numerical examples. The main findings are that clustering tends to decrease the spread of disease, the effect of...

    The problem of using 360 degrees or 180 degrees data sampling techniques in transaxial SPECT imaging is still to be solved. A theoretical point source study for an ideal response detector has shown, for objects which are close enough to the origin of the reconstructed area, that there are significant differences between sections obtained by different sampling methods. A computer simulation study of line sources in a homogeneous attenuated medium has confirmed the results of clinical studies in which significant image distortion has been observed in 180 degrees sections but not in 360 degrees reconstructed images.

    The residential-commercial energy technology model was developed as a planning tool for policy analysis in the residential and commercial building sectors. The model and its procedures represent a detailed approach to estimating the future acceptance of energy-using technologies both in new construction and for retrofit into existing buildings. The model organizes into an analytical framework all relevant information and data on building energy technology, building markets, and government policy, and it allows for easy identification of the relative importance of key assumptions. The outputs include estimates of the degree of penetration of the various building energy technologies, the levels of energy use savings associated with them, and their costs - both private and government. The model was designed to estimate the annual energy savings associated with new technologies compared with continued use of conventional technology at 1975 levels. The amount of energy used under 1975 technology conditions is referred to as the reference case energy use. For analytical purposes the technologies were consolidated into ten groupings: electric and gas heat pumps; conservation categories I, II, and III; solar thermal (hot water, heating, and cooling); photovoltaics, and wind systems. These groupings clearly do not allow an assessment of the potential for individual technologies, but they do allow a reasonable comparison of their roles in the R/C sector. Assumptions were made regarding the technical and economic performances of the technologies over the period of the analysis. In addition, the study assessed the non-financial characteristics of the technologies - aesthetics, maintenance complexity, reliability, etc. - that will also influence their market acceptability.

    Full Text Available This study identifies the status of postgraduate students at the master degree level regarding their degree completion in the three public sector universities at Jamshoro Education City. The status is identified by analyzing enrolment of the postgraduate and comparing it with rate of their degree completion. In addition, the paper also discusses their characteristics which lead them towards the degree completion. For this paper, enrolment of the postgraduate students at the master level is compared with the degree completion rate of 2008 academic session only. The result shows the obvious difference between enrolment and rate of the degree completion. In total 417 postgraduate students were enrolled in 2008 session, however, only 60 (14% of students have completed their postgraduate degrees. Those who have completed their degrees, with respect to universities 6% students belong to US (University of Sindh, 22% belong to MUET (Mehran University of Engineering & Technology and 8% students belong to LUMHS (Liaquat University of Medical & Health Sciences. The demographical data of the postgraduate students has also shown some variations like gender, age, employment, and financial resources. In addition, the research requirements also vary for different postgraduate students. The research requirements include lab based, field based and library based resources. The characteristics of the postgraduate students of three public sector universities including financial resources, employment status, and working organization also show differences with each-other in terms of the degree completion.

    Graduate education is the key support to the national competitive and technological levels. Therefore, the system of granting graduate degree was clearly guaranteed in the national level. For example, there are Education Law and Higher Education Law in China; the people' s education right is protected by federal constitution in the United States, and also universities or institutes have their own charters to claim the relative rights. The system safeguards the legitimacy of degree granting, but also gives a considerable discretionary power to the granting units who can grant or cancel the degree.

    In Italy, health protection is an individual right protected by the article 32 of the Constitution, granted to everyone since 1978 by the foundation of the National Health Service. However, regionalization of the healthcare system has caused noticeable discrepancies among the different areas of the country. The use of the Information and Communication Technology (ICT) may be useful to solve them. The purpose of this document is to analyze the implementation of ICT in Italy, on the basis of the suggestions given by the Italian Association of Hospital Cardiologists (ANMCO). In 2010, the Italian government introduced the electronic health record (EHR), which includes a minimum core of essential documents that should be created and updated by general practitioners. The obvious limitations of this methodology become clear in the urgency-emergency clinical setting, where the availability of particular clinical data may influence both patient prognosis and cost reduction. Also the privacy rules, currently very restrictive, cause a drawback in reliability of the data reported in the EHR, thus arising the need for a balance shift from privacy to health rights at the level of both the individual and the community. A minimum core of mandatory clinical data to be included in the EHR should be defined. No formal indications for filling out the medical records are available and most few experiences concern "bureaucratic documents" on the diagnostic and therapeutic process. Conversely, we believe that medical records should become a diagnostic and therapeutic tool that makes health rights uniform across the country. Each medical record form should include the following features: a simple interface, a mandatory association of clinical findings and reports, data portability and accessibility, and adherence of the information to a minimal dataset. Additionally, medical records data should merge into a modified EHR available at any time and place through network access points with

    The technology activities carried out by the Euratom-ENEA Association in the framework of the European Fusion Development Agreement concern the Next Step (International Thermonuclear Experimental Reactor - ITER), the Long-Term Programme (breeder blanket, materials, International Fusion Materials Irradiation Facility - IFMIF), Power Plant Conceptual Studies and Socio-Economic Studies. The Underlying Technology Programme was set up to complement the fusion activities as well to develop technologies with a wider range of interest. The Technology Programme mainly involves staff from the Frascati laboratories of the Fusion Technical and Scientific Unit and from the Brasimone laboratories of the Advanced Physics Technologies Unit. Other ENEA units also provide valuable contributions to the programme. ENEA is heavily engaged in component development/testing and in design and safety activities for the European Fusion Technology Programme. Although the work documented in the following covers a large range of topics that differ considerably because they concern the development of extremely complex systems, the high level of integration and coordination ensures the capability to cover the fusion system as a whole. In 2004 the most significant testing activities concerned the ITER primary beryllium-coated first wall. In the field of high-heat-flux components, an important achievement was the qualification of the process for depositing a copper liner on carbon fibre composite (CFC) hollow tiles. This new process, pre-brazed casting (PBC), allows the hot radial pressing (HRP) joining procedure to be used also for CFC-based armour monoblock divertor components. The PBC and HRP processes are candidates for the construction of the ITER divertor. In the materials field an important milestone was the commissioning of a new facility for chemical vapour infiltration/deposition, used for optimising silicon carbide composite (SiCf/SiC) components. Eight patents were deposited during 2004

    Let n and k (n ≥ k > 1) be two non-negative integers. A k-multi-hypertournament on n vertices is a pair (V, A), where V is a set of vertices with |V|= n, and A is a set of k-tuples of vertices, called arcs, such that for any k-subset S of V, A contains at least one (at most k!) of the k! k-tuples whose entries belong to S. The necessary and sufficient conditions for a non-decreasing sequence of non-negative integers to be the out-degree sequence (in-degree sequence) of some k-multi-hypertournament are given.

    2013-08-01

    Full Text Available This paper is approaching a new technique of creating Minimal Spanning Trees based on degree constraints of a simple symmetric and connected graph G. Here we recommend a new algorithm based on the average degree sequence factor of the nodes in the graph. The time complexity of the problem is less than O(N log|E| compared to the other existing time complexity algorithms is O(|E| log|E|+C of Kruskal, which is optimum. The goal is to design an algorithm that is simple, graceful, resourceful, easy to understand, and applicable in various fields starting from constraint based network design, mobile computing to other field of science and engineering.

    We investigate degree correlations in two online social networks where users are connected through different types of links. We find that, while subnetworks in which links have a positive connotation, such as endorsement and trust, are characterized by assortative mixing by degree, networks in which links have a negative connotation, such as disapproval and distrust, are characterized by disassortative patterns. We introduce a class of simple theoretical models to analyze the interplay between network topology and the superimposed structure based on the sign of links. Results uncover the conditions that underpin the emergence of the patterns observed in the data, namely the assortativity of positive subnetworks and the disassortativity of negative ones. We discuss the implications of our study for the analysis of signed complex networks.
