    Full Text Available On April 29, 2015 Reinhard Folk - member of the Editorial Board of "Condensed Matter Physics", renowned expert in the fields of condensed matter physics, phase transitions and critical phenomena - celebrated his 70th birthday. Reinhard Folk was born in Neuendettelsau, Germany. He studied at the University of Vienna, where in 1973 he defended his doctoral thesis "Hydrodynamic Equations of Dielectric Crystals" (under supervision of Franz Schwabl. In the same year he started working at the Institute for Theoretical Physics, Johannes Kepler University in Linz, at first as assistant, later as an associate professor, then as extraordinary professor, and finally as Director of the research group "Phase Transitions and Critical Phenomena". His research interests cover various fields of condensed matter physics. In particular, he obtained important results in the theory of ferroelectrics, quantum liquids, critical phenomena in magnets and random systems, spin liquids, superconductors, and neural networks. Reinhard Folk and his collaborators performed a series of studies that became the basis for understanding and quantitative description of phenomena occurring in many systems. Included amongst these are the description of the thermodynamic properties of matter in the vicinity of Lifshitz points, the description of critical dynamics in systems with different types of conservation laws, the analysis of effective (non-asymptotic critical behaviour, and generalized hydrodynamics of many-particle systems. Computing algorithms, resummation methods of asymptotic perturbation series proposed by Reinhard Folk and his collaborators, cover a wide range of applications. In 1982 (together with Volker Dohm he was awarded the Walter Schottky Prize of the German Physical Society for his studies of the critical dynamics of helium-4 . Those of us who were fortunate to know Reinhard Folk closer, are aware of his interests in the history of culture and the history of

    The high-ranking German Nazi Reinhard Heydrich (1904-1942) was one of the main organizers of the mass murder of Jews during the Second World War. He died on June 4, 1942, in Prague after having been wounded in Operation Anthropoid planned by the British intelligence services. Since the 1970s and 1980s, Heydrich's death has been frequently presented in British, American, and French literature as the consequence of a bacteriologic attack. Botulinum toxin would have been used in the grenades or ammunition. We discuss the botulinum toxin hypothesis using the now declassified British archives of Operation Anthropoid and of the chemical and bacteriologic warfare centers to assess this hypothesis. © 2017 American Academy of Neurology.

    The effect of five temperatures (15,20,25,30 and 35 degree centigree) and two levels of illumination on growth and photosynthetic activity of Chlamydomonas reinhard II has been studied. The growth of the cultures was evaluated by optical density. Photosynthetic activity has been carried out studying either the assimilation rate of C0 2 labelled with C-14 or the oxygen evolution by means of polarographic measurements. The maximum photosynthetic rate has been obtained at 25 degree centigree for the lower level of illumination (2400 lux) and at 35 degree centigree for the higher one (13200 lux) and at 35 degree centigree for the higher ono (13200 lux). These results suggest an interaction of temperature and illumination on photosynthetic activity. (Author) 37 refs

    This study was focused on determining Arsenic (As), Lead (Pb), Cadmium (Cd) and Zinc (Zn) in 33 indigenous plants and 12 soil in-situ plant samples in Thai Nguyen Province, Vietnam. The results showed that the soils of surveyed mining areas contained 181.2- 6754.3 mg kg(-1) As, 235.5-4337.2 mg kg(-1) Pb, 0.8- 419 mg kg(-1) Cd and 361.8-17565.1 mg kg(-1) Zn depending on the characteristics of each mining site. These values are much higher than those typical for normal soil. The heavy metal uptake into shoots and roots of 33 indigenous plant species was also determined. Two species of the plants investigated, Pteris vittata L. and Pityrogramma calomelanos L. were As hyperaccumulators, containing more than 0.1% heavy metals in their shoots. Eleusine indica L., Cynodon dactylon L., Cyperus rotundus L. and Equisetum ramosissimum (Vauch) accumulate very high Pb (0.15-0.65%) and Zn (0.22-1.56%) concentration in their roots. Additional experiments to clarify the potential of six these plants as good candidates for phytoremediation of heavy metal pollution soil are being carried out in our laboratory.

    Gender-based violence (GBV) has profound adverse consequences on women's physical, mental, and reproductive health. Although Vietnam has high rates of induced abortion and GBV, literature examining this relationship is lacking. This study examines the association of GBV with induced abortion among married or partnered women of reproductive age in Thai Nguyen province, Vietnam. In addition, we explore contraceptive use and unintended pregnancy as mediators in the pathway between GBV and induced abortion. Data were drawn from a cross-sectional survey of 1,281 women aged 18-49 years in four districts of Thai Nguyen province. Bivariate and multivariate logistic regression analyses were applied to examine the associations between lifetime history of GBV, contraceptive use, unintended pregnancy, induced abortion, and repeat abortion, controlling for other covariates. One-third of respondents had undergone induced abortion in their lifetime (33.4%), and 11.5% reported having repeat abortions. The prevalence of any type of GBV was 29.1% (17.0% physical violence, 10.4% sexual violence, and 20.1% emotional violence). History of GBV was associated with induced abortion (OR=1.61, 95% CI: 1.20-2.16) and repeat abortion (OR=2.22, 95% CI: 1.48-3.32). Physical violence was significantly associated with induced abortion, and all three types of violence were associated with repeat abortion. Abused women were more likely than non-abused women to report using contraceptives and having an unintended pregnancy, and these factors were in turn associated with increased risk of induced abortion. GBV is pervasive in Thai Nguyen province and is linked to increased risks of induced abortion and repeat abortion. The findings suggest that a pathway underlying this relationship is increased risk of unintended pregnancy due in part to ineffective use of contraceptives. These findings emphasize the importance of screening and identification of GBV and incorporating women's empowerment in

    Full Text Available Cardiovascular disease (CVD is one of the leading causes of morbidity and mortality in Vietnam and hypertension (HTN is an important and prevalent risk factor for CVD in the adult Vietnamese population. Despite an increasing prevalence of HTN in this country, information about the awareness, treatment, and control of HTN is limited. The objectives of this study were to describe the prevalence, awareness, treatment, and control of HTN, and factors associated with these endpoints, in residents of a mountainous province in Vietnam.Data from 2,368 adults (age≥25 years participating in a population-based survey conducted in 2011 in Thai Nguyen province were analyzed. All eligible participants completed a structured questionnaire and were examined by community health workers using a standardized protocol.The overall prevalence of HTN in this population was 23%. Older age, male sex, and being overweight were associated with a higher odds of having HTN, while higher educational level was associated with a lower odds of having HTN. Among those with HTN, only 34% were aware of their condition, 43% of those who were aware they had HTN received treatment and, of these, 39% had their HTN controlled.Nearly one in four adults in Thai Nguyen is hypertensive, but far fewer are aware of this condition and even fewer have their blood pressure adequately controlled. Public health strategies increasing awareness of HTN in the community, as well as improvements in the treatment and control of HTN, remain needed to reduce the prevalence of HTN and related morbidity and mortality.

    Full Text Available Background: Projected increases in weather variability due to climate change will have severe consequences on human health, increasing mortality, and disease rates. Among these, cardiovascular diseases (CVD, highly prevalent among the elderly, have been shown to be sensitive to extreme temperatures and heat waves. Objectives: This study aimed to find out the relationship between daily temperature (and other weather parameters and daily CVD hospital admissions among the elderly population in Thai Nguyen province, a northern province of Vietnam. Methods: Retrospective data of CVD cases were obtained from a data base of four hospitals in Thai Nguyen province for a period of 5 years from 2008 to 2012. CVD hospital admissions were aggregated by day and merged with daily weather data from this period. Distributed lag non-linear model (DLNM was used to derive specific estimates of the effect of weather parameters on CVD hospital admissions of up to 30 days, adjusted for time trends using b-splines, day of the week, and public holidays. Results: This study shows that the average point of minimum CVD admissions was at 26°C. Above and below this threshold, the cumulative CVD admission risk over 30 lag days tended to increase with both lower and higher temperatures. The cold effect was found to occur 4–15 days following exposure, peaking at a week's delay. The cumulative effect of cold exposure on CVD admissions was statistically significant with a relative risk of 1.12 (95% confidence interval: 1.01–1.25 for 1°C decrease below the threshold. The cumulative effect of hot temperature on CVD admissions was found to be non-significant and was estimated to be at a relative risk of 1.17 (95% confidence interval: 0.90–1.52 for 1°C increase in the temperature. No significant association was found between CVD admissions and the other weather variables. Conclusion: Exposure to cold temperature is associated with increasing CVD admission risk among the

    Land use changes are being interested in most countries, especially in developing countries. Because land use changes always impacts on sustainable development not only in a region or a country but also in whole the world. Viet Nam is a developing country, in the last 10 years, land uses have rapidly changed in most provinces. Many of agriculture areas, forest areas have changed for various purposes as urban sprawl, establishing new industrial parks, public areas, mining and other land uses relate to human activities or economic function associated with a specific piece of land. Beside efficiencies of economic and society, then environment issues have been threatening serious pollution, are from land use changes. Remote sensing images application on studying land use changes, has been done in many countries around the world, and has brought high efficiencies. However, this application is still very new and limited in Viet Nam due to lacking of materials, tools, experts of remote sensing. This study used spatial data as Landsat TM images, SPOT5 images and land use planning maps to rapidly assess on happenings of land uses in the period 2000 -2010 in Cong river basin (Thai Nguyen City, Viet Nam), and to forecast the changes of land uses in the period 2010 - 2020. The results had a good accuracy and to be important references for authorities, policy makers in local land use.

    Scientific learning material is still needed by students at Nguyen Tat Thanh High School (NTT), Hanoi Vietnam in order to enhance the students’ cognitive skill. Cognitive skill represents the level of students’ understanding to the particular material. Students’ cognitive skill can be improved by applying the learning material based on scientific approach as a treatment. The enhancement of students’ cognitive skill can be measured by analyzing the students’ test result collected before and after treatment. The analysis is focused to measure the enhancement or the sifted of cognitive aspects including remembering aspect (C1), understanding aspect (C2), applying aspect (C3), analyzing aspect (C4), and evaluating aspect (C5). According to the analysis the enhancement of cognitive aspects are 8.26% of remembering, 3.26% of understanding, 32.94% of applying, 21.74% of analyzing, and 21.74% of evaluating. The major enhancements are occured at applying, analyzing, and evaluating aspects. Therefore it can be concluded that students’ cognitive skill is enhanced by applying scientific learning material of static electricity.

    Socioeconomic status has a robust positive relationship with several health outcomes at the individual and population levels, but in the case of HIV prevalence, income inequality may be a better predictor than absolute level of income. Most studies showing a relationship between income inequality and HIV have used entire countries as the unit of analysis. In this study, we examine the association between income inequality at the community level and HIV prevalence in a sample of persons who inject drugs (PWID) in a concentrated epidemic setting. We recruited PWID and non-PWID community participants in Thai Nguyen, Vietnam, and administered a cross-sectional questionnaire; PWID were tested for HIV. We used ecologic regression to model HIV burden in our PWID study population on GINI indices of inequality calculated from total reported incomes of non-PWID community members in each commune. We also modeled HIV burden on interaction terms between GINI index and median commune income, and finally used a multi-level model to control for community level inequality and individual level income. HIV burden among PWID was significantly correlated with the commune GINI coefficient (r = 0.53, p = 0.002). HIV burden was also associated with GINI coefficient (β = 0.082, p = 0.008) and with median commune income (β = -0.018, p = 0.023) in ecological regression. In the multi-level model, higher GINI coefficient at the community level was associated with higher odds of individual HIV infection in PWID (OR = 1.46 per 0.01, p = 0.003) while higher personal income was associated with reduced odds of infection (OR = 0.98 per $10, p = 0.022). This study demonstrates a context where income inequality is associated with HIV prevalence at the community level in a concentrated epidemic. It further suggests that community level socioeconomic factors, both contextual and compositional, could be indirect determinants of HIV infection in PWID.

    HIV infection may be affected by multiple complex socioeconomic status (SES) factors, especially individual socioeconomic disadvantage and community-level inequality. At the same time, stigma towards HIV and marginalized groups has exacerbated persistent concentrated epidemics among key populations, such as persons who inject drugs (PWID) in Vietnam. Stigma researchers argue that stigma fundamentally depends on the existence of economic power differences in a community. In rapidly growing economies like Vietnam, the increasing gap in income and education levels, as well as an individual's absolute income and education, may create social conditions that facilitate stigma related to injecting drug use and HIV. A cross-sectional baseline survey assessing different types of stigma and key socioeconomic characteristics was administered to 1674 PWID and 1349 community members living in physical proximity throughout the 32 communes in Thai Nguyen province, Vietnam. We created four stigma scales, including HIV-related and drug-related stigma reported by both PWID and community members. We then used ecologic Spearman's correlation, ordinary least-squares regression and multi-level generalized estimating equations to examine community-level inequality associations, individual-level SES associations and multi-level SES associations with different types of stigma, respectively. There was little urban-rural difference in stigma among communes. Higher income inequality was marginally associated with drug-related stigma reported by community members (p=0.087), and higher education inequality was significantly associated with higher HIV-related stigma reported by both PWID and community members (pinequality and HIV-related stigma is superseded by the effect of individual-level education. The results of the study confirm that socioeconomic factors at both the individual level and community level affect different types of stigma in different ways. Attention should be paid to these

    Although a growing body of evidence suggests that low dead space syringes may reduce the risk of human immunodeficiency virus (HIV) and Hepatitis C virus infection associated with sharing syringes among people who inject drugs, there is little evidence of effective approaches to motivate people who inject drugs (PWID) to shift from high to low dead space syringes. Using a mix of consumer and trade marketing approaches, informed by rapid assessments of both the syringe market and PWID preferences, practices, and behaviors in Hanoi and Ho Chi Minh City, Population Services International (PSI) Vietnam piloted an intervention to increase the use of low dead space syringes (LDSS) in the three provinces of Hanoi, Ho Chi Minh City, and Thai Nguyen, where an estimated 31% of PWID are HIV positive and 58% are living with hepatitis C virus (HCV). This paper provides a summary of the social marketing activities implemented and results achieved by PSI Vietnam during an initial 1-year pilot period from December 2012 to December 2013 in these three provinces to explore their effectiveness in motivating PWID to use low dead space syringes. We found major increases in sales of LDSS accompanied by increases in reported use and consistent use of LDSS among PWID in the three provinces included in the pilot program and a positive and independent association (odds ratio (OR) 21.08; 95% confidence interval (CI) 10.6-27.3) between LDSS use and exposure to social marketing activities. We also found that LDSS use had a stronger association with perceptions of LDSS product quality than with perceptions regarding LDSS potential to reduce HIV transmission risk and use. We conclude that social marketing interventions have an important role to play in widening access to and the use of LDSS for PWID, as they address the need for PWID to find LDSS when and where they need them and also promote the benefits of LDSS use to PWID. High coverage of these activities among PWID appears to be the key in

    Globally, 30% of new HIV infections outside sub-Saharan Africa involve injecting drug users (IDU) and in many countries, including Vietnam, HIV epidemics are concentrated among IDU. We conducted a randomized controlled trial in Thai Nguyen, Vietnam, to evaluate whether a peer oriented behavioral intervention could reduce injecting and sexual HIV risk behaviors among IDU and their network members. 419 HIV-negative index IDU aged 18 years or older and 516 injecting and sexual network members were enrolled. Each index participant was randomly assigned to receive a series of six small group peer educator-training sessions and three booster sessions in addition to HIV testing and counseling (HTC) (intervention; n = 210) or HTC only (control; n = 209). Follow-up, including HTC, was conducted at 3, 6, 9 and 12 months post-intervention. The proportion of unprotected sex dropped significantly from 49% to 27% (SE (difference) = 3%, p < 0.01) between baseline and the 3-month visit among all index-network member pairs. However, at 12 months, post-intervention, intervention participants had a 14% greater decline in unprotected sex relative to control participants (Wald test = 10.8, df = 4, p = 0.03). This intervention effect is explained by trial participants assigned to the control arm who missed at least one standardized HTC session during follow-up and subsequently reported increased unprotected sex. The proportion of observed needle/syringe sharing dropped significantly between baseline and the 3-month visit (14% vs. 3%, SE (difference) = 2%, p < 0.01) and persisted until 12 months, but there was no difference across trial arms (Wald test = 3.74, df = 3, p = 0.44).

Former students of the editor, Dr. Gisela Steins, a professor for general psychology and social psychology, each summarized their final papers in essays. Most of the essays contain smaller empirical studies on the topic of school and gender. The two final contributions deal with the themes of body disaffection and the sensitization of school children toward processes of stigmatization using the example of obesity. Gisela Steins herself composed an introduction as well as short transitions between the articles. The students’ articles are for the most part interesting, although the question remains at to the book’s intended audience.

    This study from Vietnam shows that a switch from conventional to organic tea productions would bring real environmental, health and economic benefits for the country's farmers and its society as a whole. In particular, the amount of agrochemical residue and waste produced by tea production would be reduced. Farmers would also be able to enjoy a better livelihood as they could command a premium price for their organic tea products. The study therefore recommends that organic tea production is ...

    Background In Vietnam, an estimated 256,000 people are living with HIV, and 58% of HIV-infections reported are among people who inject drugs (PWID). While antiretroviral therapy (ART) is widely available in Vietnam, marginalized hard-to-reach male PWID, demonstrate significantly reduced and delayed access to ART. Methods We investigated the effect of a randomized four-arm multi-level intervention trial on ART initiation among male PWID. Our analysis was conducted among a subset of trial participants (n = 136), who were newly diagnosed as HIV-infected, treatment naïve, and eligible for ART (baseline late diagnosis). The trial arms included: 1, standard of care (HIV testing and counseling); 2, structural-level intervention (door-to-door communications and community video screenings); 3, individual-level intervention (counseling plus group support); and 4, individual-level plus structural-level intervention. In a time-to-event analysis, we used a non-parametric approach for competing risks to estimate cumulative incidence function (CIF) for ART initiation (event of interest) by arm and the difference in CIF for each trial arm as compared to Arm 1. Follow-up was conducted at 6, 12, 18 and 24 months. Data collection occurred from 2009 to 2013. Findings By 24-months, 61.0% initiated ART, and 30.9% had died prior to ART initiation. In the first 6 months, participants in arm 4 (individual plus community intervention) had a 28% (95% confidence interval (CI): 6–50%) increased probability of initiating ART. Despite increasing coverage of ART in all arms throughout follow-up, participants in arm 4 retained a 31% (95% CI: 5–56%) increased probability of initiating ART. The individual and community components of the intervention were only effective when delivered together. Conclusions Marginalized, hard-to-reach men, who do not routinely engage in HIV services, and therefore come into care late, may benefit significantly from both individual counseling and group support, in combination with community-focused stigma reduction, when being referred and attempting to initiate urgently needed ART.

    Full Text Available Objective – As part of a multi‐staged project, this study seeks to identify the unanswered questions about users as found in three fields: library and information science (LIS, human computer interaction, and communication and media studies, as well as the convergences and divergences across these fields.Design – A multi‐phased, qualitative study involving individual face‐to‐face and telephone interviews, as well as self interviewing and focus groups.Setting – The fields of LIS, human computer interaction, and communication and media studies as examined in interview situations.Subjects – 83 international experts across the three fields, as well as 31 local experts from central Ohio, USA.Methods – The majority of the 83 international experts in the fields of LIS, human computer interaction, and communication and media studies were interviewed by telephone (some in person.Thirty‐one local experts (7 public and 24 academic library directors were individually interviewed and also took part in focus groups. The Sense‐Making Methodology was used as an interview approach with its emphasis on bridging gaps. Neutral interview questions were used to tease out the gaps in certain situations— in the case of this project, the gaps involve communication and the unanswered questions about users. Brenda Dervin developed this approach, which has been transformed and adapted by Dervin and a host of other LIS researchers over the past 25 years. It is a metatheoretical approach that has “evolved into a generalized communication‐based methodology seen as useful for the study of human sense‐making (and sense‐unmaking in any context”(Dervin 729. The Sense‐Making metatheory is implemented three ways in the method: “in the framing of research questions; in the designing of interviewing; and in the analyzing and concluding processes of research” (Dervin 737. In the research under review for this summary the answers to the gap‐identifying questions allow different disciplines to begin to communicate and understand each other. Using Sense‐Making in focus groups involves self interviewing (diaries, journals and group discussions. Interviews were transcribed using the “smooth verbatim approach” in which nonfluencies such as repetition, hesitancies, and partial words are eliminated. Care was taken to ensure anonymity, as this is necessary in the first step of the Sense‐Making approach. The transcripts were analyzed for themes to capture a broad picture of what the participants struggle with across disciplinary and research practicedivides. Analysis was carried out by using comparative coding developed in early grounded theory combined with the Sense‐Making methodology’s emphasis on gaps and bridging gaps. The “quotablequote” was the unit of analysis, and thematically representative quotes were selected from the transcriptions.Main Results – In an attempt to analyze communication across and within disciplines, the researchers did a thematic analysis on the interviews conducted with their international and local experts. The thematic analysis found 12 major themes, which included a total of 75 sub themes. The 12 major themes include the following:Participants wanted to make a difference with their work; participants agreed that current user research is not doing the job;there are fundamental disagreements about users and user studies; there are fundamental disagreements about the purposes of using user studies; there are external forces that make carrying out andapplying user studies difficult; there was a lengthy list of differing suggestions for improving user studies; interdisciplinary communication across the three fields that do user studies is not effective; it was agreed that interdisciplinary contact is difficult;communication across the research/practice divide is not going well; some participants saw academic researchers as the problem, while some participants viewed practitioners as the problem; and most participants agreed that contact across fields and the research/practice divide would be beneficial. The researchers contend that this analysis is one of many that could be done on the information retrieved from the interviews. Their goal was not to find the definitive answers, but to describe the difficulties that participants are having across disciplines and across the research/practice divide in terms of communication and relating to user studies. The researchers wanted to tease out implications for communication and to illustrate the multiplicity that they found.Conclusion – It is difficult for this study to draw conclusions except in the most general sense, as it is part of a larger, multi‐staged research project. However, this study did find that although participants across fields wanted a synthesis, they also expressed their inability to understand syntheses fromfields other than their own. There were some who wanted more theories, while some claimed there were too many theories already. There was much criticism about communication across disciplines, but few solutions offered. The researchers can offer up no “magic wands” as solutions for these results, but they do suggest that the modes of communication traditionally used in user studies research are not working.

    A new model of cracking process in ceramics is developed assuming the fracture of the grain just ahead of a flaw, such as a crack or a notch, during the loading process, prior to the final unstable fracture. Based on the grain fracture model, a simulation was carried out to explain the anomalous behavior of small flaws and the notch width effect, which were reported by Evans and Langdon (1976) and Hoshide et al. (1984) and by Bertolotti (1973) and Pabst et al. (1982), respectively. It is shown that the analytical relations of the new model can explain the experimental results for both situations.

  2. From Blogs to Books: Blogging as Community, Practice and Platform

    Directory of Open Access Journals (Sweden)

    William Caraher

    2015-05-01

    Full Text Available This article expands a 2008 article prepared by William Caraher for Archaeology Online which celebrated the first generation of scholarly blogging in archaeology and classics. Caraher remains tremendously optimistic that the widespread accessibility of blogging platforms, the growth of social media, and new expectation for academic publication has created new communities of scholarly practice poised to revolutionize archaeological communication. Andrew Reinhard offers a more cautionary perspective on the relationship between blogging and publishing by introducing a global perspective on academic publishing and some of the practical issues related to including blogs within the larger tent of scholarly communication. Reinhard's perspectives reveal that the communities of practice in academia may not always be compatible, but like both article authors, they leave plenty of room for new publishing possibilities in a range of rapidly changing digital media and platforms.

  12. Planning ideology and geographic thought in the early twentieth century: Charles Whitnall's progressive era park designs for socialist Milwaukee.

    Science.gov (United States)

    Platt, Lorne A

    2010-01-01

    As Milwaukee’s chief park planner in the early to mid-twentieth century, Charles Whitnall responded to the various underlying ideologies of the period within which he worked. His preference for parks was a political and physical response to and remedy for the industrialized and heavily congested city he called home. By examining the Progressive Era discourse associated with planning, this article situates Whitnall’s work within the political, aesthetic, and environmental contexts of geographic thought that influenced his plans for Milwaukee. In promoting a physical awareness associated with the natural features of the region and responding to the sociopolitical framework of contemporaries such as Ebenezer Howard, Whitnall incorporated a sense of compassion within his planning. He responded to the preexisting beer gardens of Pabst and Schlitz, as well as Olmsted-designed park spaces, by advocating for decentralization as part of a broader socialist agenda that had swept through Milwaukee during the early 1900s.

  13. [Madness in the German cinema (1913-1933].

    Science.gov (United States)

    Aulas, J J

    1980-01-01

    During these twenty years, from 1913 to 1933, of the history of the German cinema, the cinematographic representation of madness varies according to the fluctuations of the social and economical background. The political and ideological chaos of the immediate post-war years was symbolized in the allegorical imagery of unreason in the expressionist cinema. The same equivalence, the same symbolization can be found in the cinema of the thirties when the crash of Wall-Street foretells a crisis like the former. On the contrary in the course of the so-called "relative stabilization" (1924-1929) the meaning of the representation of madness is totally different from the representation of the previous period. At this period of economical restoration, madness which could henceforth be cured on the psychoanalyst's couch (acc. G. W. Pabst's film: "Geheimnisse einer Seele") became the symbol of the absolute power rediscovered by Germany.

    If the ARD political talk show with Guenther Jauch starts on Sunday night after the crime thriller, only few viewers know that they are tele-guests on the former gasometer site in Berlin-Schoeneberg. Currently, this site is being transformed into an environmentally friendly campus called the 'European Energy Forum' (EUREF). According to the will of the owner and architect Reinhard Mueller, the campus will become the largest CO{sub 2} neutral office and business location in Europe. Totally 600 million Euro will be invested. All new buildings should be ecological 'green buildings' and received the LEED Gold certification.

    2004-01-01

    The results on elemental analysis of the Vietnamese ancient bronze coins during the time of the Nguyen dynasty (19th century) are presented. The samples were provided by the vietnam National Historical Museum and the elemental analysis was performed on the home-made model EDS-XT-99-01 X-ray fluorescence spectrometer in the Institute of Materials Science, NCST of Vietnam. The samples exited simultaneously by radioisotope source and X-ray tube. The analytical results show the similarity in the elemental composition of the coins issued by different kings of the Nguyen dynasty, but there is the difference in the concentration of the used elements. Another interesting point is that all the coins have zinc (Zn) in their composition, which shows clearly the influence of the occidental metallurgical technology on the money-making technique in Vietnam during the 19th century.

    Hi-Plex is a suite of methods to enable simple, accurate, and cost-effective highly multiplex PCR-based targeted sequencing (Nguyen-Dumont et al., Biotechniques 58:33-36, 2015). At its core is the principle of using gene-specific primers (GSPs) to "seed" (or target) the reaction and universal primers to "drive" the majority of the reaction. In this manner, effects on amplification efficiencies across the target amplicons can, to a large extent, be restricted to early seeding cycles. Product sizes are defined within a relatively narrow range to enable high-specificity size selection, replication uniformity across target sites (including in the context of fragmented input DNA such as that derived from fixed tumor specimens (Nguyen-Dumont et al., Biotechniques 55:69-74, 2013; Nguyen-Dumont et al., Anal Biochem 470:48-51, 2015), and application of high-specificity genetic variant calling algorithms (Pope et al., Source Code Biol Med 9:3, 2014; Park et al., BMC Bioinformatics 17:165, 2016). Hi-Plex offers a streamlined workflow that is suitable for testing large numbers of specimens without the need for automation.

Strong CD44 expression in this population indicates its important role in maintaining the stem cell phenotype. Previous studies show that CD44 down-regulation causes CD44+CD24- breast cancer stem cells to differentiate into non-stem cells that are sensitive to antitumor drugs and lose many characteristics of the original cells. In this study, we determined tumor suppression in non-obese severe combined immunodeficiency mice using CD44 shRNA therapy combined with doxorubicin treatment.Methods: Tumor-bearing non-obese severe combined immunodeficiency mice were established by injection of CD44+CD24- cells. To track CD44+CD24- cells, green fluorescence protein was stably transduced using a lentiviral vector prior to injection into mice. The amount of CD44 shRNA lentiviral vector used for transduction was based on CD44 down-regulation by in vitro CD44 shRNA transduction. Mice were treated with direct injection of CD44 shRNA lentiviral vector into tumors followed by doxorubicin administration after 48 hours. The effect was evaluated by changes in the size and weight of tumors compared with that of the control.Results: The combination of CD44 down-regulation and doxorubicin strongly suppressed tumor growth with significant differences in tumor sizes and weights compared with that of CD44 down-regulation or doxorubicin treatment alone. In the combination of CD44 down-regulation and doxorubicin group, the tumor weight was

    Narrative coaching is representative of the new wave – or third generation – of coaching practice . The theory and practice of narrative coaching takes into account the social and cultural conditions of late modern society, and must be seen as intertwined with them. Some initial conceptualizations...... of narrative coaching were developed by David Drake (2006, 2007, 2008, 2009) in the USA and Australia, by Ho Law in the UK (Law, 2007a + b; Law & Stelter, 2009) and by Reinhard Stelter (2007, 2009, 2012, in preparation; Stelter & Law, 2010) in Denmark. In the following chapter the aim is to present coaching...... as a narrative-collaborative practice, an approach that is based on phenomenology, social constructionism and narrative theory. Seeing narrative coaching as a collaborative practice also leads to reflecting on the relationship between coach and coachee(s) in a new way, where both parts contribute to the dialogue...

    Seeking to popularise the broad research programme undertaken by the LHC experiments, three members of the ATLAS collaboration, Michael Barnett, Kaushik De and Reinhard Schwienhorst, had the idea of reaching new audiences through a planetarium show. Given the thousands of planetariums worldwide, this project could have an astronomical impact…   A snapshot from the ATLAS planetarium show looking distorted when not projected onto a dome (courtesy of Joao Pequenao). "The full-length show will go from the Big Bang to galaxies to underground experiments and possibly AMS before coming to ATLAS for the final third or fourth,” explains Michael Barnett from Lawrence Berkeley Lab (LBL). While much of the media attention has focused on the Higgs boson, this project will show how an experiment like ATLAS can search for dark matter and explain other great mysteries in physics. “We are working with George Smoot, experts from seven major planetariums worldwide, and m...

    A new rhizocephalan species, Peltogaster unigibba n. sp., is described from the host hermit crab, Pagurixus boninensis (Melin, 1939), from the Bonin Islands, Japan. Of the16 known species of Peltogaster now currently recognised, P. unigibba n. sp., and P. contorta Boschma, 1958 share a left lobe that projects beyond the mantle aperture. The two species can be distinguished from one another by the position of the opening of the mantle aperture. The new species most closely resembles P. naushonensis Reinhard, 1946 in its internal structure, but clearly differs in the relative length of the colleteric glands. Peltogaster unigibba n. sp. represents the first record of a rhizocephalan from the oceanic Bonin Islands, and the second record of a rhizocephalan from an oceanic island in the northern hemisphere.

    I arrived in Berkeley in October 1983 as a post-doc, and my appointment was at the Space Sciences Laboratory (SSL). During that time the group was very large, with multiple activities led by Charlie himself and also by Senior Fellows such as John Lacy, Dan Jaffe, and Al Betz at the top of the hill at Space Sciences. Another significant contingent of the Townes group was housed in Birge Hall on campus, led by Reinhard Genzel when he was an Assistant Professor in the Physics Department. Although the group encompassed two separate locations, it functioned as one large group. Either we rode with Charlie up and down the hill, or (if we were concerned about our safety!) we took the bus.

    ’s right to freedom of thought. We argue that this objection can be challenged. First, we present some specifications of what a right to freedom of thought might mean. We focus on the recently published views of Jared Craig, and Jan Cristopher Bublitz and Reinhard Merkel. Secondly, we argue that forcing...... violent offenders to undergo certain kinds of NT may not violate the offender’s right to freedom of thought as that right is specified by Craig, and Bublitz and Merkel. Thirdly, even if non-consensual NT is used in a way that does violate freedom of thought, such use can be difficult to abandon without...... inconsistency. For if one is not an abolitionist, and therefore accepts traditional state punishments for violent offenders like imprisonment – which, the evidence shows, often violate the offender’s right to freedom of thought – then, it is argued, one will have reason to accept that violent offenders can...

    We are investigating phenomena that stem from the many body dynamics associated with ionization of an atom or molecule by photon or charged particle. Our program is funded through the Department of Energy EPSCoR Laboratory Partnership Award in collaboration with Lawrence Berkeley National Laboratory. We are using variations on the well established COLTRIMS technique to measure ions and electrons ejected during these interactions. Photoionization measurements take place at the Advanced Light Source at LBNL as part of the ALS-COLTRIMS collaboration with the groups of Reinhard Dörner at Frankfurt and Ali Belkacem at LBNL. Additional experiments on charged particle impact are conducted locally at Auburn University where we are studying the dissociative molecular dynamics following interactions with either ions or electrons over a velocity range of 1 to 12 atomic units.

Seu objetivo é elaborar uma concepção teórica alternativa às abordagens personalistas e patrimonialistas desses fenômenos, assim como às percepções conjunturais e pragmáticas, produto da parcelização e fragmentação do conhecimento, que perdem o vínculo com qualquer realidade mais ampla e totalizadora.This article discusses and matches some contemporary theories on the origin and dynamics of social recognition, such as Charles Taylor's, and sociocultural approaches to the subject of inequality, such as Pierre Bourdieu's and Reinhard Kreckel's, in order to apply them, in a modified and productive way, to central matters of peripheral modernity, such as the undercitizenship and the naturalization of inequality. Its aim is to develop an alternative conception to the patrimonialist and personalist approaches to the subject, as well as to short-range and pragmatic perceptions, which are the result of the partition and fragmentation of knowledge, unconcerned about understanding a more embracing reality.

    The present feasibility study about 'Car-sharing in rural areas' is the joint production of a project consortium from science and practice. The consortium was composed of two chairs in the field of business management of the Carl von Ossietzky University (Chair for general business management studies, company management and business-related environmental policy, Prof. Dr. Reinhard Pfriem and the Chair for general business management studies, sales and marketing, Prof. Dr. Thorsten Raabe), a Chair in the field of traffic science of the Technical University of Dresden (Chair for traffic ecology, Prof. Dr. Udo J. Becker) as well as the federal association Carsharing (bcs) (Martin Stutzbach). The joint target of the working group members was to justify a 'model experiment Carsharing in rural areas' and to test it in terms of feasibility. The question whether the Carsharing concept can be transferred from conurbations to rural areas is supposed to be investigated in a most extensive scientific framework and at the same time closely oriented to the practice by means of a model experiment as research approach.

    HIV infection is common among people who inject drugs (PWID), and HIV-positive PWID may be particularly vulnerable to depression. This study measured the prevalence of depressive symptoms and the factors associated with severe symptoms among 455 HIV-positive PWID in Thai Nguyen, Vietnam. We used cross-sectional data from PWID in a randomized controlled trial of an intervention to reduce high-risk injecting and sexual behaviors in Thai Nguyen from 2009-2013. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression Scale (CES-D). We used logistic regression to assess demographic, clinical, and psychosocial predictors of severe depressive symptoms (CES-D≥23) with prevalence odds ratios (POR) and 95% confidence intervals (CI). The prevalence of severe depressive symptoms (CES-D≥23) was 44%. 25% of participants had mild to moderate depressive symptoms (16≤CES-D<23), and 31% experienced no depressive symptoms (CES-D<16). Not being married, self-rated poor health, greater frequency of injection drug use, history of overdose, no alcohol use, and daily cigarette smoking were positively associated with severe depressive symptoms in unadjusted models and remained predictive in a multivariable model. The strongest predictors of depressive symptoms were self-reported poor health (POR = 2.94, 95% CI: 1.82, 4.76), no current alcohol use (POR = 2.35, 95% CI: 1.47, 3.77), and not currently married or cohabitating (POR = 2.21, 95% CI = 1.40, 3.47). Severe depressive symptoms were common among HIV-positive PWID in Thai Nguyen and were strongly associated with demographic, clinical, and psychosocial factors. Interventions that promote social support from family and reduce drug dependence may particularly benefit PWID experiencing severe depressive symptoms. Greater recognition and treatment of depressive symptoms has the potential to enhance quality of life and improve HIV clinical outcomes for PWID.

Both the conference and the workshop were held from 29 July to 1 August 2013 in Pullman hotel, Da Nang, Vietnam. The IWTCP-1 was a new activity of the Vietnamese Theoretical Physics Society (VTPS) organized in association with the 38th National Conference on Theoretical Physics (NCTP-38), the most well-known annual scientific forum dedicated to the dissemination of the latest development in the field of theoretical physics within the country. The IWTCP-1 was also an External Activity of the Asia Pacific Center for Theoretical Physics (APCTP). The overriding goal of the IWTCP is to provide an international forum for scientists and engineers from academia to share ideas, problems and solution relating to the recent advances in theoretical physics as well as in computational physics. The main IWTCP motivation is to foster scientific exchanges between the Vietnamese theoretical and computational physics community and world-wide scientists as well as to promote high-standard level of research and education activities for young physicists in the country. About 110 participants coming from 10 countries participated in the conference and the workshop. 4 invited talks, 18 oral contributions and 46 posters were presented at the conference. In the workshop we had one keynote lecture and 9 invited talks presented by international experts in the fields of theoretical and computational physics, together with 14 oral and 33 poster contributions. The proceedings were edited by Nguyen Tri Lan, Trinh Xuan Hoang, and Nguyen Ai Viet. We would like to thank all invited speakers, participants and sponsors for making the conference and the workshop successful. Nguyen Ai Viet Chair of NCTP-38 and IWTCP-1

    We prove in this paper that the periodic cyclic homology of the quantized algebras of functions on coadjoint orbits of connected and simply connected Lie group, are isomorphic to the periodic cyclic homology of the quantized algebras of functions on coadjoint orbits of compact maximal subgroups, without localization. Some noncompact quantum groups and algebras were constructed and their irreducible representations were classified in recent works of Do Ngoc Diep and Nguyen Viet Hai [DH1]-[DH2] by using deformation quantization. In this paper we compute their K-groups, periodic cyclic homology groups and their Chern characters. (author)

    2000-08-01

    The goal of this paper is to present EMATOOLS, a set of scripts for displaying and annotating acoustic and articulatory data simultaneously in studies on speech production. These scripts were developed with the use of MATLAB, a multiplatform computing environment for numeric computation and visualization. The system is equipped with a mouse-driven graphical interface made up of a number of displays. This interface can be easily customized to speed up routine tasks. The scripts can also be used in a noninteractive way, as stand-alone MATLAB commands. Output data can be imported into any standard spreadsheet.

    This sampling and analysis plan (SAP) identifies characterization objectives pertaining to sample collection, laboratory analytical evaluation, and reporting requirements for grab samples obtained to address waste compatibility. It is written in accordance with requirements identified in Data Quality Objectives for Tank Farms Waste Compatibility Program (Mulkey et al. 1999) and Tank Farm Waste Transfer Compatibility Program (Fowler 1999). In addition to analyses to support Compatibility, the Waste Feed Delivery program has requested that tank samples obtained for Compatibility also be analyzed to confirm the high-level waste and/or low-activity waste envelope(s) for the tank waste (Baldwin 1999). The analytical requirements to confirm waste envelopes are identified in Data Quality Objectives for TWRS Privatization Phase I: Confirm Tank T is an Appropriate Feed Source for Low-Activity Waste Feed Batch X (Nguyen 1999a) and Data Quality Objectives for RPP Privatization Phase I: Confirm Tank T is an Appropriate Feed Source for High-Level Waste Feed Batch X (Nguyen 1999b)

  16. Refining a definition of reflection for the being as well as doing the work of a physician.

    Science.gov (United States)

    Wald, Hedy S

    2015-04-21

    Reflection is core to professional competency and supports the active, constructive process of professional identity formation. Medical educators thus grapple with operationalizing and effectively integrating reflection as a foundational construct within health care professions education and practice. Core elements of reflection including role of emotions and awareness of self, other and situation, do not appear within various working definitions of reflection. This observation as well as noted recent shift in medical education toward emphasis on the "being" as well as "doing the work" of a physician led to the author's proposed refining of Sandars' reflection definition and expansion of Nguyen et al.'s reflection model. A refined reflection definition is offered for a more inclusionary approach. A caveat regarding potential for expected reflective learning outcomes (given reflection as a process) is provided and the integral role of mentor-enhanced reflection is discussed. Reflection as a continuum is highlighted and exemplified within Wald et al.'s REFLECT rubric and Nguyen et al.'s reflection model.

  17. FSILP: fuzzy-stochastic-interval linear programming for supporting municipal solid waste management.

    Science.gov (United States)

    Li, Pu; Chen, Bing

    2011-04-01

    Although many studies on municipal solid waste management (MSW management) were conducted under uncertain conditions of fuzzy, stochastic, and interval coexistence, the solution to the conventional linear programming problems of integrating fuzzy method with the other two was inefficient. In this study, a fuzzy-stochastic-interval linear programming (FSILP) method is developed by integrating Nguyen's method with conventional linear programming for supporting municipal solid waste management. The Nguyen's method was used to convert the fuzzy and fuzzy-stochastic linear programming problems into the conventional linear programs, by measuring the attainment values of fuzzy numbers and/or fuzzy random variables, as well as superiority and inferiority between triangular fuzzy numbers/triangular fuzzy-stochastic variables. The developed method can effectively tackle uncertainties described in terms of probability density functions, fuzzy membership functions, and discrete intervals. Moreover, the method can also improve upon the conventional interval fuzzy programming and two-stage stochastic programming approaches, with advantageous capabilities that are easily achieved with fewer constraints and significantly reduces consumption time. The developed model was applied to a case study of municipal solid waste management system in a city. The results indicated that reasonable solutions had been generated. The solution can help quantify the relationship between the change of system cost and the uncertainties, which could support further analysis of tradeoffs between the waste management cost and the system failure risk.

    In the paper the result of elemental analysis by Nuclear Techniques of Coal and Embedded rocks samples from Vietnamese Quang Ninh and Thai Nguyen basins were presented. Methods used were: Neutron activation Analysis at Dalat Reactor, low counting with HP-Ge and NaJ detectors and X-ray fluorescent analysis with planar Si (Si) detector. Mean concentrations of 19 elements in coal and 9 in rocks were determined. Correlation between concentrations of elements were found. It appears that the correlation between ash content and U, K, Th, concentrations was poor for Quang Ninh antracitecoal. Correlation coefficient was found to be 0,63 for ash range 0-40%. Content of Th in anthracite Quang Ninh coal was much higher than reported in literature for subbituminous, bituminous and lignite coals, while Thai Nguyen fat coal contains considerable amount of Cu, Pb, Zn. Obtained data were useful for evaluation of potential hazard for environment from using coal as fuel for coal fired power plants, for estimation of possibility of using nuclear technique in coal industry in Vietnam. They could be used also for geochemical investigations. The simple of-line coal ash gauge basing on attenuation of soft gamma radiation from Fe-55 was also described.

    In investigations of laminar or turbulent flows, wall shear is often important. Nevertheless, conventional particle image velocimetry (PIV) is difficult in near-wall regions. A near-wall measurement technique, named interfacial PIV (IPIV) [Nguyen, C., Nguyen, T., Wells, J., Nakayama, A., 2008. Proposals for PIV of near-wall flow over curved boundaries. In: Proceedings of 14th International Symposium on Applications of Laser Technique to Fluid Mechanics], handles curved boundaries by means of conformal transformation, directly measures the wall gradient, and yields the near-wall tangential velocity profile at one-pixel resolution. In this paper, we show the feasibility of extending IPIV to measure wall gradients by stereo reconstruction. First, we perform a test on synthetic images generated from a direct numerical simulation (DNS) snapshot of turbulent flow over sinusoidal bed. Comparative assessment of wall gradients derived by IPIV, stereo-IPIV and particle image distortion (PID) [Huang, H.T., Fiedler, H.E., Wang, J.J., 1993. Limitation and improvement of PIV. Experiments in Fluids 15(4), 263-273] is evaluated with DNS data. Also, the sensitivity of IPIV and stereo-IPIV results to the uncertainty of identified wall position is examined. As a practical application of IPIV and stereo-IPIV to experimental images, results from turbulent open channel flow over a backward-facing step are discussed in detail.

    neutral projectiles can nevertheless not be treated by usual available calculations, and certainly not in the framework of a unique theoretical approach. In the present work we have adapted the non adiabatic approach of Calvayrac et al. [1] to the case of organic molecule and we apply it to realistic irradiation scenarios. This method contains as limiting cases pure electron dynamics and BO dynamics (Car-Parinello dynamics) and can thus describe collisions with high-velocity charged or low-velocity neutral projectiles. Moreover, at variance with currently available approaches, it enables complementing cases to be described such as low velocity charged and high-velocity neutral projectiles. Indeed such a non adiabatic approach places no restriction on the velocity or charge state of the projectile and thus offers an unified picture of many possible irradiation scenarios. Furthermore this approach can be extended to account for environment effects in a hierarchical picture, which will be extremely useful to treat large water environments [2]. We illustrate the capabilities of the method on irradiation of ethylene [3], and water molecules [4] and clusters. References: [1] Non linear electron dynamics in metal clusters, F. Calvayrac, P. G.

    In translational research, efficient knowledge exchange between the different fields of expertise is crucial. An open platform that is capable of storing a multitude of data types such as clinical, pre-clinical or OMICS data combined with strong visual analytical capabilities will significantly accelerate the scientific progress by making data more accessible and hypothesis generation easier. The open data warehouse tranSMART is capable of storing a variety of data types and has a growing user community including both academic institutions and pharmaceutical companies. tranSMART, however, currently lacks interactive and dynamic visual analytics and does not permit any post-processing interaction or exploration. For this reason, we developed SmartR , a plugin for tranSMART, that equips the platform not only with several dynamic visual analytical workflows, but also provides its own framework for the addition of new custom workflows. Modern web technologies such as D3.js or AngularJS were used to build a set of standard visualizations that were heavily improved with dynamic elements.

    Full Text Available Kathrin Wunsch, Nadine Kasten, Reinhard Fuchs Department of Sport Science, Sport Psychology Unit, Albert-Ludwigs University Freiburg, Freiburg im Breisgau, Germany Abstract: The stress-buffering hypothesis postulates that physical activity and exercise can buffer the negative effects of (academic stress on health. It still remains an open question whether students, who regularly engage in physical activity and exercise within their academic examination period, can successfully diminish these negative effects. Sixty-four subjects participated in this study and completed a total of five surveys, with T1 at the end of the semester break (baseline and T2–T5 being presented every Friday in the last 4 weeks of the semester (examination period. They were asked to answer questions about their activity level, sleep quality, well-being and affect. Hierarchical linear models showed significant dependencies on time for all dependent measures. The expansion of the model for exercise also showed significant main effects of this predictor on well-being and positive affect (PA and negative affect. Moreover, significant interactions with time for sleep quality and PA were found. Results suggest that physical activity and exercise in the academic examination period may be able to buffer the negative effects of stress on health-related outcomes. Therefore, activity levels should be maintained in times of high stress to prevent negative effects on sleep, well-being and affect in students.

    ''Quanta 5'' contains the two speeches on the member meeting of the Heisenberg society in october 2016. Reinhard Werner talked about the meaning of Heisenberg's uncertainty relation and its interpretation in the framework of quantum mechanics. Johannes Bluemer reported about the works on cosmic radiation, which were performed during the second world war in Berlin and after the war in the Max-Planck institute for physics in Goettingen, as well as about the results of the latest experiments on the cosmic radiation. Reprinted is furthermore Heisenberg's speech ''Wandlungen der Grundlagen der exakten Naturwissenschaft in juengster Zeit'', which he gave in the meeting of the natural researchers at 17.9.1934 in Hanover. It is the reaction of Heisenberg on the attacks by Johannes Stark and Philipp Lenard on Jewish scientists and on the developments of modern Physics, especially on Einstein's relativity theory and quantum mechanics. The closure of the volume forms an essay of Tobias Jung about the importance of Heisenberg's house in Urfeld above the Bavarian Walchensee.

    Full Text Available Hoje, cem anos depois das maiores batalhas navais e de trincheiras, cabe a pergunta: como esta Grande Guerra Europeia mudou não somente as configurações do continente, mas também os conceitos de guerra e de literatura de guerra? Até o século XIX, a guerra era vista por muitos como um ato heroico, pelo qual os homens podiam comprovar a sua valentia numa luta aberta, encarando diretamente o inimigo. Com a nova tecnologia de armas, a morte vem de forma invisível: gás, submarinos, artilharias de longo alcance, minas, aviões, tanques e metralhadoras. Muda-se a estratégia bélica e finda o sentimento de uma luta nobre para defender a pátria. Neste artigo, a grande desilusão com a guerra será exemplificada através dos romances Nada de novo no front (1929 de Erich Maria Remarque, Os quatro cavaleiros do Apocalipse (1916 de Vicente Blasco Ibáñez, abarcando a guerra terrestre, assim como o drama expressionista Batalha naval (1917 de Reinhard Göring.

    2014-11-01

    Full Text Available German Society for Sexual Research, Academy of Sexual Medicine and Society of Sexology formulated standards for evaluation and treatment of transsexuals. The creation of the standards involved Sophinette Becker, Hartmut A. G. Bosinski, Ulrich Clement, Wolf Eicher, Thomas M. Goerlich, Uwe Hartmann, Götz Kockott, Dieter Langer, Wilhelm E. Preuss, Gunter Schmidt, Alfred Springer, Reinhard Wille. Since 1980, the Federal Republic of Germany has a law on transsexualism, which regulates the right of the individual to change the sex. However, until now there were no specifically defined standards of assessment and treatment of transsexuals. For the first time, in 1979 Harry Benjamin invited the International Medical Association of Germany to revise the standards of medical care for gender dysphoria. The following standards of assessment and treatment of transsexuals have been developed at a conference convened by the German Society for Research Expert Committee under the leadership of Sophinette Becker. The review of currently valid standards for evaluation and treatment of transgender is the subject of this article

  8. Beam profiles for fast neutrons; and reply

    International Nuclear Information System (INIS)

    Bewley, D.K.; Parnell, C.J.; Bloch, P.

    1976-01-01

    The authors express surprise that Bloch et al. (Bloch, P.H., Hendry, G.O., Hilton, J.L., Quam, W.M., Reinhard, D.K., and Wilson, C., 1976, Phys. Med. Biol., Vol. 21, 450) justified a target size of 5.5 x 5.5 cm in a neutron generator by comparison with the profile given by a 2.5 MV X-ray generator. The penumbral width of this new neutron generator is more than twice that of a modern megavoltage X-ray machine, and larger than those of beams from standard 60 Co units, or of the Hammersmith Hospital cyclotron beam. The large target size of the neutron generator may have to be accepted as a necessary evil, but should not be considered satisfactory. In reply, one of the authors of the original note presents the results of calculations of beam profiles for 14 MeV neutron beams in a tissue-equivalent phantom, and suggests that the broader profiles are principally caused by the larger probability of side scatter, not by source size. The most fruitful approach to sharpening the neutron beam profile would seem to be to design a field flattening filter to increase relative dose near the edge inside the geometrically defined field. Calculations indicating that Bewley and Parnell have underestimated the penumbral widths of 60 Co beams are also presented. (U.K.)

    The immune response to bacterial infection represents a complex network of dynamic gene and protein interactions. We present an optimized reverse engineering strategy aimed at a reconstruction of this kind of interaction networks. The proposed approach is based on both microarray data and available biological knowledge. The main kinetics of the immune response were identified by fuzzy clustering of gene expression profiles (time series). The number of clusters was optimized using various evaluation criteria. For each cluster a representative gene with a high fuzzy-membership was chosen in accordance with available physiological knowledge. Then hypothetical network structures were identified by seeking systems of ordinary differential equations, whose simulated kinetics could fit the gene expression profiles of the cluster-representative genes. For the construction of hypothetical network structures singular value decomposition (SVD) based methods and a newly introduced heuristic Network Generation Method here were compared. It turned out that the proposed novel method could find sparser networks and gave better fits to the experimental data. Reinhard.Guthke@hki-jena.de.

    Apart from an early case report from China (13th century), the first observations on insects and other arthropods as forensic indicators were documented in Germany and France during mass exhumations in the 1880s by Reinhard, who is considered a co-founder of the discipline. After the French publication of Mégnin's popular book on the applied aspects of forensic entomology, the concept quickly spread to Canada and United States. At that time, researchers recognized that the lack of systematic observations of insects of forensic importance jeopardized their use as indicators of postmortem interval. General advances in insect taxonomy and ecology helped to fill this gap over the following decades. After World Wars, few forensic entomology cases were reported in the scientific literature. From 1960s to the 1980s, Leclercq and Nuorteva were primarily responsible for maintaining the method in Central Europe, reporting isolated cases. Since then, basic research in the USA, Russia and Canada opened the way to the routine use of Entomology in forensic investigations. Identifications of insects associated with human cadavers are relatively few in the literature of the Neotropical region and have received little attention in Brazil. This article brings an overview of historic developments in this field, the recent studies and the main problems and challenges in South America and mainly in Brazil.

    ''Quanta 5'' contains the two speeches on the member meeting of the Heisenberg society in october 2016. Reinhard Werner talked about the meaning of Heisenberg's uncertainty relation and its interpretation in the framework of quantum mechanics. Johannes Bluemer reported about the works on cosmic radiation, which were performed during the second world war in Berlin and after the war in the Max-Planck institute for physics in Goettingen, as well as about the results of the latest experiments on the cosmic radiation. Reprinted is furthermore Heisenberg's speech ''Wandlungen der Grundlagen der exakten Naturwissenschaft in juengster Zeit'', which he gave in the meeting of the natural researchers at 17.9.1934 in Hanover. It is the reaction of Heisenberg on the attacks by Johannes Stark and Philipp Lenard on Jewish scientists and on the developments of modern Physics, especially on Einstein's relativity theory and quantum mechanics. The closure of the volume forms an essay of Tobias Jung about the importance of Heisenberg's house in Urfeld above the Bavarian Walchensee.

    We are actively pursuing applications of thermoelastic (elastocaloric) cooling using shape memory alloys. Latent heat associated with martensitic transformation of shape memory alloys can be used to run cooling cycles with stress-inducing mechanical drives. The coefficient of performance of thermoelastic cooling materials can be as high as 11 with the directly measured DT of around 17 °C. Depending on the stress application mode, the number of cycles to fatigue can be as large as of the order of 105. Efforts to design and develop thermoelastic alloys with long fatigue life will be discussed. The current project at the University of Maryland is focused on development of building air-conditioners, and at Maryland Energy and Sensor Technologies, smaller scale commercial applications are being pursued. This work is carried out in collaboration with Jun Cui, Yiming Wu, Suxin Qian, Yunho Hwang, Jan Muehlbauer, and Reinhard Radermacher, and it is funded by the ARPA-E BEETIT program and the State of Maryland.

J Strength Cond Res 31(5): 1282-1289, 2017-The primary purpose of this study was to examine concurrent validity of the jump-and-reach (JaR) test using the Vertec system and a criterion device (i.e., Optojump system). In separate subanalyses, we investigated the influence of gym floor condition and athletes' sex on the validity of vertical jump height. Four hundred forty subelite adolescent female (n = 222, mean age: 14 ± 1 year, age range: 13-15 years) and male (n = 218, mean age: 15 ± 1 year, age range: 14-16 years) handball players performed the JaR test in gyms with region or point elastic floors. Maximal vertical jump height was simultaneously assessed using the Vertec and the Optojump systems. In general, significantly higher jump heights were obtained for the Vertec compared with the Optojump system (11.2 cm, Δ31%, Cohen's d = 2.58). The subanalyses revealed significantly larger jump heights for the Vertec compared with the Optojump system irrespective of gym floor condition and players' sex. The association between Optojump- and Vertec-derived vertical jump heights amounted to rP = 0.84, with a coefficient of determination (R) of 0.71. The subanalyses indicated significantly larger correlations in males (rP = 0.75, R = 0.56) than in females (rP = 0.63, R = 0.40). Yet, correlations were not significantly different between region (rP = 0.83, R = 0.69) as opposed to point elastic floor (rP = 0.87, R = 0.76). Our findings indicate that the 2 apparatuses cannot be used interchangeably. Consequently, gym floor and sex-specific regression equations were provided to estimate true (Optojump system) vertical jump height from Vertec-derived data.

    We propose a scheme to teleport a two-mode entangled coherent state encoded with two-qubit information, which is better than the two schemes recently proposed by Liao and Kuang (2007 J. Phys. B: At. Mol. Opt. Phys. 40 1183) and by Phien and Nguyen (2008 Phys. Lett. A 372 2825) in that our scheme gives higher value of minimum assured fidelity and minimum average fidelity without using any nonlinear interactions. For involved coherent states | {+-} {alpha}), minimum average fidelity in our case is {>=}0.99 for |{alpha}| {>=} 1.6 (i.e. |{alpha}|{sup 2} {>=} 2.6), while previously proposed schemes referred above report the same for |{alpha}| {>=} 5 (i.e. |{alpha}|{sup 2} {>=} 25). Since it is very challenging to produce superposed coherent states of high coherent amplitude (|{alpha}|), our teleportation scheme is at the reach of modern technology.

    New experimental data indicate that mass flux in cocurrent gas-liquid flows may be determined by the use of Pitot tubes in conjunction with a local mixture density measurement technique. The data were taken over a wide range of flow regimes in a horizontal pipe and included separated patterns such as stratified and annular flows. Local mixture densities were obtained by a computer-assisted algebraic reconstruction technique that used chordal average densities measured by traversing gamma beam attenuation. The results extend the applicability of this mass flux measurement technique well beyond the relatively homogeneous, high-pressure, steam-water flow situations originally studied by S. Banerjee and D.M. Nguyen. 13 refs

    The first step towards the understanding and the modelling of the Fe–Cr alloy kinetic properties consists in estimating the migration energies related to the processes that drive the microstructure evolution. The vacancy’s migration barrier is expected to depend on the vacancy–migrating atom pair atomic environment as pointed out by Nguyen-Manh et al. or Bonny et al. In this paper, we address the issue of the dependence on the vacancy’s local atomic environment of both the vacancy migration energy and the configurational energy change ΔE that occurs when the vacancy jumps towards one of its nearest neighbour sites. A DFT approach is used to determine the ground state energy associated to a given configuration of the system. The results are interpreted in the light of the chromium–chromium and chromium–vacancy binding energies as well as the substitutional chromium atoms magnetic properties.

    Images acquired by cameras installed in tokamaks are difficult to interpret because the three-dimensional structure of the plasma is flattened in a non-trivial way. Nevertheless, taking advantage of the slow variation of the fluctuations along magnetic field lines, the optical transformation may be approximated by a generalized Abel transform, for which we proposed in Nguyen van yen et al., Nucl. Fus., 52 (2012) 013005, an inversion technique based on the wavelet-vaguelette decomposition. After validation of the new method using an academic test case and numerical data obtained with the Tokam 2D code, we present an application to an experimental movie obtained in the tokamak Tore Supra. A comparison with a classical regularization technique for ill-posed inverse problems, the singular value decomposition, allows us to assess the efficiency. The superiority of the wavelet-vaguelette technique is reflected in preserving local features, such as blobs and fronts, in the denoised emissivity map.

    Full Text Available An in vitro sensitivity test was conducted to study the sensitivity of Plasmodium falciparum against chloroquine and pyrimethamine/sulphadoxine combination. The relationship between sensitivity of the parasite to the two drugs was also studied. A total of 72 patients from five localities were examined during 1984-1985. Test against chloroquine was conduc­ted according to WHO method, while against pyrimethamine/sulphadoxine combination, a modified method of Nguyen Dinh and Payne and Eastham and Rieckmann was used. The results showed that there is no relationship between the sensitivity of P. falciparum against pyrimethamine/ sulphadoxine combination and chloroquine. It can be concluded that in case of chloroquine resistant P. falciparum, pyrimethamine/sulphadoxine combination could be applied as an alternative chemotherapy.

    In a recent editorial we examined the research outputs of 150 Australian nursing and midwifery professors (McKenna, Cooper, Cant, Bogossian, 2017) identifying publication metrics on par with, and sometimes above those of professors in the UK (Watson, McDonagh & Thompson, 2016). Because global university rankings are heavily weighted towards research, there has been pressure on universities and on academics to maximise research performance (Nguyen, Rambaldi & Tang, 2017). Although many Australian universities have increasingly focused on education delivery, and despite the need for a strong evidence base for learning and teaching, academics are often cautioned against focusing too heavily on educational research.

  9. On the equivalence of two approaches in the exciton-polariton theory

    International Nuclear Information System (INIS)

    Ha Vinh Tan; Nguyen Toan Thang

    1983-02-01

    The polariton effect in the optical processes involving photons with energies near that of an exciton is investigated by the Bogolubov diagonalization and the Green function approaches in a simple model of the direct band gap semiconductor with the electrical dipole allowed transition. To take into account the non-resonant terms of the interaction Hamiltonian of the photon-exciton system the Green function approach derived by Nguyen Van Hieu is presented with the use of Green's function matrix technique analogous to that suggested by Nambu in the theory of superconductivity. It is shown that with the suitable choice of the phase factors the renormalization constants are equal to the diagonalization coefficients. The disperson of polaritons and the matrix elements of processes with the participation of polaritons are identically calculated by both methods. However the Green function approach has an advantage in including the damping effect of polaritons. (author)

The purpose of this sampling event is to obtain information about the characteristics of the contents of 241-AY-101 required to satisfy ''Data Quality Objectives For RPP Privatization Phase I: Confirm Tank T Is An Appropriate Feed Source For High-Level Waste Feed Batch X(HLW DQO)' (Nguyen 1999a), ''Data Quality Objectives For TWRS Privatization Phase I: Confirm Tank T Is An Appropriate Feed Source For Low-Activity Waste Feed Butch X (LAW DQO) (Nguyen 1999b)'', ''Low Activity Waste and High-Level Waste Feed Data Quality Objectives (L and H DQO)'' (Patello et al. 1999), and ''Characterization Data Needs for Development, Design, and Operation of Retrieval Equipment Developed through the Data Quality Objective Process (Equipment DQO)'' (Bloom 1996). Special instructions regarding support to the LAW and HLW DQOs are provided by Baldwin (1999). Push mode core samples will be obtained from risers 15G and 150 to provide sufficient material for the chemical analyses and tests required to satisfy these data quality objectives. The 222-S Laboratory will extrude core samples; composite the liquids and solids; perform chemical analyses on composite and segment samples; archive half-segment samples; and provide sub-samples to the Process Chemistry Laboratory. The Process Chemistry Laboratory will prepare test plans and perform process tests to evaluate the behavior of the 241-AY-101 waste undergoing the retrieval and treatment scenarios defined in the applicable DQOs. Requirements for analyses of samples originating in the process tests will be documented in the corresponding test plans and are not within the scope of this SAP

    By considering the Einstein-Vlasov system for static spherically symmetric distributions of matter, we show that configurations with constant anisotropy parameter β , leading to asymptotically flat spacetimes, have necessarily a distribution function (DF) of the form F =l-2 βξ (ɛ ) , where ɛ =E /m and l =L /m are the relativistic energy and angular momentum per unit rest mass, respectively. We exploit this result to obtain DFs for the general relativistic extension of the hypervirial family introduced by Nguyen and Lingam [Mon. Not. R. Astron. Soc. 436, 2014 (2013), 10.1093/mnras/stt1719], which Newtonian potential is given by ϕ (r )=-ϕo/[1 +(r /a )n]1 /n (a and ϕo are positive free parameters, n =1 ,2 ,… ). Such DFs can be written in the form Fn=ln -2ξn(ɛ ) . For odd n , we find that ξn is a polynomial of order 2 n +1 in ɛ , as in the case of the Hernquist model (n =1 ), for which F1∝l-1(2 ɛ -1 ) (ɛ-1 ) 2 . For even n , we can write ξn in terms of incomplete beta functions (Plummer model, n =2 , is an example). Since we demand that F ≥0 throughout the phase space, the particular form of each ξn leads to restrictions for the values of ϕo. For example, for the Hernquist model we find that 0 ≤ϕo≤2 /3 , i.e., an upper bounding value less than the one obtained for Nguyen and Lingam (0 ≤ϕo≤1 ), based on energy conditions.

    Despite increasing appreciation for parasitism as an important component of primate ecology and evolution, surprisingly few studies have demonstrated the costs of helminth parasitism in primates. Detecting parasite-related costs in primates is particularly difficult because it requires detailed, long-term data on individual host reproductive success, survival, and parasitism. The identification of the larval tapeworm Taenia serialis in geladas under intensive long-term study in the Ethiopian Highlands (Nguyen et al. [2015] American Journal of Primatology, 77:579-594; Schneider-Crease et al. [2013] Veterinary Parasitology 198:240-243) provides an opportunity to examine how an endemic parasite impacts host reproductive success and survival. We used survival analyses to assess the mortality risk associated with protuberant larval cysts characteristic of T. serialis using a decade of data from a gelada population in the Simien Mountains National Park (SMNP), Ethiopia. We demonstrated strikingly high mortality associated with T. serialis cysts in adult females, particularly for younger adults. The estimated effect of cysts on male mortality was similar, although the effect was not statistically significant, likely owing to the smaller sample size. Additionally, the offspring of mothers with cysts experienced increased mortality, which was driven almost entirely by maternal death. Mothers with cysts had such high mortality that they rarely completed an interbirth interval. Comparison with a study of this parasite in another gelada population on the Guassa Plateau (Nguyen et al. [2015] American Journal of Primatology, 77:579-594) revealed lower cyst prevalence in the SMNP and similar cyst-associated mortality. However, many more females with cysts completed interbirth intervals at Guassa than in the SMNP, suggesting that T. serialis cysts may kill hosts more rapidly in the SMNP. Our results point toward the underlying causes of individual and population

    Type 2 diabetes mellitus (T2DM) represents a rapidly increasing threat to global public health. T2DM arises largely from obesity, poor diet, and lack of exercise, but it also involves genetic predisposition. Here we report that the KCNE2 potassium channel transmembrane regulatory subunit is expressed in human and mouse pancreatic β cells. Kcne2 deletion in mice impaired glucose tolerance as early as 5 wk of age in pups fed a Western diet, ultimately causing diabetes. In adult mice fed normal chow, skeletal muscle expression of insulin receptor β and insulin receptor substrate 1 were down-regulated 2-fold by Kcne2 deletion, characteristic of T2DM. Kcne2 deletion also caused extensive pancreatic transcriptome changes consistent with facets of T2DM, including endoplasmic reticulum stress, inflammation, and hyperproliferation. Kcne2 deletion impaired β-cell insulin secretion in vitro up to 8-fold and diminished β-cell peak outward K + current at positive membrane potentials, but also left-shifted its voltage dependence and slowed inactivation. Interestingly, we also observed an aging-dependent reduction in β-cell outward currents in both Kcne2 +/+ and Kcne2 - / - mice. Our results demonstrate that KCNE2 is required for normal β-cell electrical activity and insulin secretion, and that Kcne2 deletion causes T2DM. KCNE2 may regulate multiple K + channels in β cells, including the T2DM-linked KCNQ1 potassium channel α subunit.-Lee, S. M., Baik, J., Nguyen, D., Nguyen, V., Liu, S., Hu, Z., Abbott, G. W.

Strong expression of CD44 plays a critical role in numerous types of human cancers. CD44 is involved in cell differentiation, adhesion, and metastasis of cancer cells.Methods: In this study, we reduced CD44 expression in CD44+CD24- breast cancer stem cells and investigated their sensitivity to an antitumor drug. The CD44+CD24- breast cancer stem cells were isolated from breast tumors; CD44 expression was downregulated with siRNAs followed by treatment with different concentrations of the antitumor drug.Results: The proliferation of CD44 downregulated CD44+CD24- breast cancer stem cells was decreased after drug treatment. We noticed treated cells were more sensitive to doxorubicin, even at low doses, compared with the control groups.Conclusions: It would appear that expression of CD44 is integral among the CD44+CD24- cell population. Reducing the expression level of CD44, combined with doxorubicin treatment, yields promising results for eradicating breast cancer stem cells in vitro. This study opens a new direction in treating breast cancer through gene therapy in conjunction with chemotherapy.Keywords: antitumor drugs, breast cancer stem cells, CD44, CD44+CD24- cells, doxorubicin

  17. CFD study of fluid flow changes with erosion

    For the first time, a three dimensional mesh deformation algorithm is used to assess fluid flow changes with erosion. The validation case chosen is the Jet Impingement Test, which was thoroughly analysed in previous works by Hattori et al. (Kenichi Sugiyama and Harada, 2008), Gnanavelu et al. in (Gnanavelu et al., 2009, 2011), Lopez et al. in (Lopez et al., 2015) and Mackenzie et al. in (Mackenzie et al., 2015). Nguyen et al. (2014) showed the formation of a new stagnation area when the wear scar is deep enough by performing a three-dimensional scan of the wear scar after 30 min of jet impingement test. However, in the work developed here, this stagnation area was obtained solely by computational means. The procedure consisted of applying an erosion model in order to obtain a deformed geometry, which, due to the changes in the flow pattern lead to the formation of a new stagnation area. The results as well as the wear scar were compared to the results by Nguyen et al. (2014) showing the same trend. OpenFOAM® was the software chosen for the implementation of the deforming mesh algorithm as well as remeshing of the computational domain after deformation. Different techniques for mesh deformation and approaches to erosion modelling are discussed and a new methodology for erosion calculation including mesh deformation is developed. This new approach is independent of the erosion modelling approach, being applicable to both Eulerian and Lagrangian based equations for erosion calculation. Its different applications such as performance decay in machinery subjected to erosion as well as modelling of natural erosion processes are discussed here.

    The International Conference on Highly Frustrated Magnetism 2008 (HFM2008) took place on 7-12 September 2008 at the Technische Universität Carolo-Wilhelmina zu Braunschweig, Germany. This conference was the fourth event in a series of meetings, which started in Waterloo, Canada (HFM 2000), followed by the second one in Grenoble, France (HFM 2003), and the third meeting in Osaka, Japan (HFM 2006). HFM2008 attracted more than 220 participants from all over the world. The number of participants of the HFM conference series has been increasing steadily, from about 80 participants at HFM 2000, to 120 participants at HFM 2003, and 190 participants at HFM 2006, demonstrating that highly frustrated magnetism remains a rapidly growing area of research in condensed matter physics. At the end of HFM2008 it was decided that the next International Conference on Highly Frustrated Magnetism will be held in Baltimore, USA in 2010. HFM2008 saw four plenary talks by R Moessner, S Nakatsuji, S-W Cheong, and S Sachdev, 18 invited presentations, 30 contributed talks and about 160 poster presentations from all areas of frustrated magnetism. The subjects covered by the conference included: Kagome systems Itinerant frustrated systems Spinels and pyrochlore materials Triangular systems Unconventional order and spin liquids Chain systems Chain systems Novel frustrated systems This volume of Journal of Physics: Conference Series contains the proceedings of HFM2008 with 83 papers that provide a scientific record of the scientific topics covered by the conference. All articles have been refereed by experts in the field. It is our hope that the reader will enjoy and profit from the HFM2008 Proceedings.

  19. Trasmissione del sapere musicale e storia della cultura europea nei primi decenni del secolo XV

    Full Text Available L’evoluzione storico-musicale nella prima metà del Quattrocento è caratterizzata dall’internazionalizzazione della cultura musicale europea ed si pone in continuità con il processo culturale del primo umanesimo. La categoria di ‘evoluzione’ e l’idea stessa di ‘rinascita’, ovvero quella “leggenda di un progresso” (Martin Le Franc, Johannes Tinctoris discussa da Reinhard Strohm, sono concetti che oggi devono essere letti non soltanto nel senso di una omologazione stilistica, ma anche come aspetto distintivo di una ricerca d’identità culturale. Anche dal punto di vista storico-musicale siamo di fronte alla costituzione di un nuovo gusto europeo nato dalla fusione di stili e di pratiche locali che si espanderà, grazie alla trasmissione delle compilazioni manoscritte, per tutto il continente e al quale aderiranno, in maniera disomogenea, anche compositori di regioni più remote.Il Concilio di Basilea non costituisce solo un dato storico circoscrivibile agli anni in cui si svolse il sinodo, così come non è da considerarsi solo un fatto empirico riguardante la sola città della Svizzera settentrionale. Esso deve piuttosto essere assunto come un evento paradigmatico per la storia della cultura del Quattrocento. Gli incontri fra intellettuali ed artisti, l’interazione fra musicisti di diverse regioni europee che si incontravano grazie ai frequentissimi spostamenti delle corti e delle cappelle, fanno del Concilio la piattaforma virtuale sia per la ricerca di una nuova identità culturale sia per la nascita di nuovi repertori e pratiche musicali. Il Concilio trascende quindi i confini contingenti della città di Basilea trasformandosi in una vera e propria “dinamica culturale” in cui i singoli individui contribuiscono alla continua trasmissione e fusione di esperienze musicali diventando vettori di una nuova mentalità musicale che raggiunse anche gli angoli più remoti dell’Europa.

  20. Marine redox structure at the culmination of the Great Oxidation Event: Insights from the Zaonega Formation, Karelia, Russia

    The availability of dissolved oxygen is thought to have been the dominant throttle on the evolution and diversification of eukaryotic life during the Proterozoic Eon [1]. In the mid-Proterozoic, during the interval that presaged the rise of eukaryotes to ecological dominance, oxygen scarcity is thought to have relegated eukaryotic organisms to slivers of oxygenated shallow oceans [2]. However, recent work has suggested that oxygen levels rose dramatically during the early Paleoproterozoic Great Oxidation Event before crashing to the low levels of the mid-Proterozoic [3]. Evidence from selenium isotopes in shales [4] and iodate concentrations in carbonates [5] has even suggested that wide swathes of continental shelves were oxic enough to support eukaryotic organisms at this time. How oxic though, and for how long, remain poorly constrained. Here we present new selenium geochemical data from the Zaonega Formation of Karelia, Russia that can help resolve those questions. Previous work has proposed that the Zaonega Formation, and correlative Francevillian Series of Gabon, record the establishment of an oxygen-rich atmosphere at the culmination of the GOE [6]. Our selenium isotope dataset provides a test for this hypothesis, and can also be used to assess the preservation of the geochemical signatures in the Zaonega Formation. These data point to regional redox fluctuations, but due to the short marine residence time of selenium, extrapolating these results to global phenomena remains difficult. 1.

    In this paper an interview with director of the Nabucco project, Reinhard Mitchek is published. There is extract from this interview: Iranian gas is a politically sensitive topic Europe cannot avoid I believe that it will become a topic in Europe in the medium to long term. Shouldn't Europe declare that it needs Iranian gas? Otherwise Russia or China may take over. I do not want to advise the European Commission via the media. Iranian gas would bring the Nabucco project closer to reality. A common European Union (EU) foreign policy and common foreign energy policy in particular will be of major importance. We of course need competition in the EU gas sector. But that is a business topic. The political issue is the competitiveness of Europe as an entity competing for energy sources with other regions. The European Union keeps repeating that the Nabucco project has high priority. But what steps has it undertaken to support it? The Commissioner for Energy, Andris Piebalgs, and the Commissioner for External Relations and European Neighbourhood Policy, Benita Ferrero-Waldner, visited Central Asia and supported the export of gas to Europe. That is exactly what Russia does and with more success. We will see. Naturally - these countries have a history of relationships with Russia. Turkmenistan and Kazakhstan have been exporting gas to Russia. But in the meantime these countries also want to extend their export portfolio. We think that through the Trans-Caspian pipeline and the existing gas pipeline connecting Azerbaijan with Turkey, gas from Azerbaijan and Turkmenistan will also get to Nabucco. (authors)

    2017-01-01

    El título Memorias del presente y del futuro corresponde precisamente a esta coyuntura, en la que convergen relatos de vida abortados, así como procesos históricos de amplio alcance, tácticas y estrategias de resistencia, macro- y micropolíticas. Al formular la convocatoria para el número teníamos en mente que la memoria, como acto colectivo de rememoración, articula el pasado, el presente y el futuro, y queríamos ir más allá de la noción habitual de memoria como anclada en el pasado, focalizada en una serie de hechos que se sitúan en un tiempo y un espacio que resultan significativos para alguien desde el presente. Si bien el pasado parece un país extraño al que queremos retornar, como lo ha dicho el escritor David Lowenthal (1998, igualmente, asumimos que la memoria es un ámbito de lo cotidiano. En ella se conecta temporal- y biográficamente la dimensión de la experiencia, aquello que le ha sucedido a alguien y de lo que es posible dar cuenta, a través de la narración o de los silencios, con la dimensión de la expectativa, con lo que aún no es, pero se presenta como guía de acción. Así, la memoria, si bien recoge la experiencia acumulada de dolor y esperanza, también condensa horizontes, como bien lo ha mostrado el filósofo de la historia Reinhard Koselleck (1993

  4. Quantum information processing with graph states

    International Nuclear Information System (INIS)

    Schlingemann, Dirk-Michael

    2005-04-01

    Graph states are multiparticle states which are associated with graphs. Each vertex of the graph corresponds to a single system or particle. The links describe quantum correlations (entanglement) between pairs of connected particles. Graph states were initiated independently by two research groups: On the one hand, graph states were introduced by Briegel and Raussendorf as a resource for a new model of one-way quantum computing, where algorithms are implemented by a sequence of measurements at single particles. On the other hand, graph states were developed by the author of this thesis and ReinhardWerner in Braunschweig, as a tool to build quantum error correcting codes, called graph codes. The connection between the two approaches was fully realized in close cooperation of both research groups. This habilitation thesis provides a survey of the theory of graph codes, focussing mainly, but not exclusively on the author's own research work. We present the theoretical and mathematical background for the analysis of graph codes. The concept of one-way quantum computing for general graph states is discussed. We explicitly show how to realize the encoding and decoding device of a graph code on a one-way quantum computer. This kind of implementation is to be seen as a mathematical description of a quantum memory device. In addition to that, we investigate interaction processes, which enable the creation of graph states on very large systems. Particular graph states can be created, for instance, by an Ising type interaction between next neighbor particles which sits at the points of an infinitely extended cubic lattice. Based on the theory of quantum cellular automata, we give a constructive characterization of general interactions which create a translationally invariant graph state. (orig.)

    Having investigated the decision making of world class elite and subelite athletes (see Parkin and Walsh, 2017; Parkin et al., 2017), here the abilities of those at the earliest stage of entry to elite sport are examined. Junior elite athletes have undergone initial national selection and are younger than athletes examined previously (mean age 13 years). Decision making under mental pressure is explored in this sample. During performance an athlete encounters a wide array of mental pressures; these include the psychological impact of errors, negative feedback, and requirements for sustained attention in a dynamic environment (Anshel and Wells, 2000; Mellalieu et al., 2009). Such factors increase the cognitive demands of the athletes, inducing distracting anxiety-related thoughts known as rumination (Beilock and Gray, 2007). Mental pressure has been shown to reduce performance of decision-making tasks where reward and loss contingencies are explicit, with a shift toward increased risk taking (Pabst et al., 2013; Starcke et al., 2011). Mental pressure has been shown to be detrimental to decision-making speed in comparison to physical stress, highlighting the importance of considering a range of different pressures encountered by athletes (Hepler, 2015). To investigate the influence of mental pressure on key indicators of decision making in junior elite athletes. This chapter concludes a wider project examining decision making across developmental stages in elite sport. The work further explores how psychological insights can be applied in an elite sporting environment and in particular tailored to the requirements of junior athletes. Seventeen junior elite athletes (10 males, mean age: 13.80 years) enrolled on a national youth athletic development program participated in the study. Performance across three categories of decision making was assessed under conditions of low and high mental pressure. Decision making under risk was measured via the Cambridge Gambling

    This sampling and analysis plan (SAP) identifies characterization objectives pertaining to sample collection, laboratory analytical evaluation, and reporting requirements for samples obtained from tank 241-AZ-102. The purpose of this sampling event is to obtain information about the characteristics of the contents of 241-AZ-102 required to satisfy the Data Quality Objectives For TWRS Privatization Phase I : Confirm Tank TIS An Appropriate Feed Source For High-Level Waste Feed Batch X(HLW DQO) (Nguyen 1999a), Data Quality Objectives For TWRS Privatization Phase 1: Confirm Tank TIS An Appropriate Feed Source For Low-Activity Waste Feed Batch X (LAW DQO) (Nguyen 1999b), Low Activity Waste and High Level Waste Feed Data Quality Objectives (L and H DQO) (Patello et al. 1999) and Characterization Data Needs for Development, Design, and Operation of Retrieval Equipment Developed through the Data Quality Objective Process (Equipment DQO) (Bloom 1996). The Tank Characterization Technical Sampling Basis document (Brown et al. 1998) indicates that these issues, except the Equipment DQO apply to tank 241-AZ-102 for this sampling event. The Equipment DQO is applied for shear strength measurements of the solids segments only. Poppiti (1999) requires additional americium-241 analyses of the sludge segments. Brown et al. (1998) also identify safety screening, regulatory issues and provision of samples to the Privatization Contractor(s) as applicable issues for this tank. However, these issues will not be addressed via this sampling event. Reynolds et al. (1999) concluded that information from previous sampling events was sufficient to satisfy the safety screening requirements for tank 241-AZ-102. Push mode core samples will be obtained from risers 15C and 24A to provide sufficient material for the chemical analyses and tests required to satisfy these data quality objectives. The 222-S Laboratory will extrude core samples, composite the liquids and solids, perform chemical analyses

    Background A life-shortening strain of the obligate intracellular bacteria Wolbachia, called wMelPop, is seen as a promising new tool for the control of Aedes aegypti. However, developing a vector control strategy based on the release of mosquitoes transinfected with wMelPop requires detailed knowledge of the demographics of the target population. Methodology/Principal Findings In Tri Nguyen village (611 households) on Hon Mieu Island in central Vietnam, we conducted nine quantitative entomologic surveys over 14 months to determine if Ae. aegypti populations were spatially and temporally homogenous, and to estimate population size. There was no obvious relationship between mosquito (larval, pupal or adult) abundance and temperature and rainfall, and no area of the village supported consistently high numbers of mosquitoes. In almost all surveys, key premises produced high numbers of Ae. aegypti. However, these premises were not consistent between surveys. For an intervention based on a single release of wMelPop-infected Ae. aegypti, release ratios of infected to uninfected adult mosquitoes of all age classes are estimated to be 1.8–6.7∶1 for gravid females (and similarly aged males) or teneral adults, respectively. We calculated that adult female mosquito abundance in Tri Nguyen village could range from 1.1 to 43.3 individuals of all age classes per house. Thus, an intervention could require the release of 2–78 wMelPop-infected gravid females and similarly aged males per house, or 7–290 infected teneral female and male mosquitoes per house. Conclusions/Significance Given the variability we encountered, this study highlights the importance of multiple entomologic surveys when evaluating the spatial structure of a vector population or estimating population size. If a single release of wMelPop-infected Ae. aegypti were to occur when wild Ae. aegypti abundance was at its maximum, a preintervention control program would be necessary to ensure that there was no

    Autism is currently considered a multigene disorder with epigenetic influences. To investigate the contribution of DNA methylation to autism spectrum disorders, we have recently completed large-scale methylation profiling by CpG island microarray analysis of lymphoblastoid cell lines derived from monozygotic twins discordant for diagnosis of autism and their nonautistic siblings. Methylation profiling revealed many candidate genes differentially methylated between discordant MZ twins as well as between both twins and nonautistic siblings. Bioinformatics analysis of the differentially methylated genes demonstrated enrichment for high-level functions including gene transcription, nervous system development, cell death/survival, and other biological processes implicated in autism. The methylation status of 2 of these candidate genes, BCL-2 and retinoic acid-related orphan receptor alpha (RORA), was further confirmed by bisulfite sequencing and methylation-specific PCR, respectively. Immunohistochemical analyses of tissue arrays containing slices of the cerebellum and frontal cortex of autistic and age- and sex-matched control subjects revealed decreased expression of RORA and BCL-2 proteins in the autistic brain. Our data thus confirm the role of epigenetic regulation of gene expression via differential DNA methylation in idiopathic autism, and furthermore link molecular changes in a peripheral cell model with brain pathobiology in autism.—Nguyen, A., Rauch, T.

    Full Text Available Nancy Nguyen1, Mark Holodniy21University of the Pacific School of Pharmacy and Health Sciences, Stockton, CA, USA; 2VA Palo Alto Health Care System, Palo Alto, CA, USAAbstract: In the US, an estimated 1 million people are infected with HIV, although one-third of this population are unaware of their diagnosis. While HIV infection is commonly thought to affect younger adults, there are an increasing number of patients over 50 years of age living with the condition. UNAIDS and WHO estimate that of the 40 million people living with HIV/AIDS in the world, approximately 2.8 million are 50 years and older. With the introduction of highly active antiretroviral therapy (HAART in the mid-1990s, survival following HIV diagnosis has risen dramatically and HIV infection has evolved from an acute disease process to being managed as a chronic medical condition. As treated HIV-infected patients live longer and the number of new HIV diagnoses in older patients rise, clinicians need to be aware of these trends and become familiar with the management of HIV infection in the older patient. This article is intended for the general clinician, including geriatricians, and will review epidemiologic data and HIV treatment as well as provide a discussion on medical management issues affecting the older HIV-infected patient.Keywords: HIV, epidemiology, treatment, aging, review

    The adsorption of gases on microporous carbons is still poorly understood, partly because the structure of these carbons is not well known. Here, a model of microporous carbons based on fullerene-like fragments is used as the basis for a theoretical study of Ar adsorption on carbon. First, a simulation box was constructed, containing a plausible arrangement of carbon fragments. Next, using a new Monte Carlo simulation algorithm, two types of carbon fragments were gradually placed into the initial structure to increase its microporosity. Thirty six different microporous carbon structures were generated in this way. Using the method proposed recently by Bhattacharya and Gubbins (BG), the micropore size distributions of the obtained carbon models and the average micropore diameters were calculated. For ten chosen structures, Ar adsorption isotherms (87 K) were simulated via the hyper-parallel tempering Monte Carlo simulation method. The isotherms obtained in this way were described by widely applied methods of microporous carbon characterisation, i.e. Nguyen and Do, Horvath-Kawazoe, high-resolution α s plots, adsorption potential distributions and the Dubinin-Astakhov (DA) equation. From simulated isotherms described by the DA equation, the average micropore diameters were calculated using empirical relationships proposed by different authors and they were compared with those from the BG method

    1977-01-01

    A special purpose computer code (Ratch) was developed to analyse a thin circular cylinder subjected to axisymmetrical mechanical and thermal loadings. The Mendelson's approach of this problem is followed. Classical Kirchoff-Love hypothesis of thin shells is used and a state of plane stress is assumed. Space integrations are performed by Gaussian quadrature in the axial direction and by Simpson's one third rule throughout the thickness. Thermoelastic-plastic constitutive equations are solved with an implicit scheme (Nguyen). Thermovisco-plastic constitutive equations are solved with an explicit time integration scheme (Treanor's algorithm especially fitted). A Bree type diagram is obtained for an axial step of temperature which varies cyclically and a sustained constant axial load. The material behavior is assumed perfectly plastic and creep effect is not considered. Results show that the domain where ratchetting occurs is reduced when compared with the domain predicted by the Bree diagram. To investigate the effect of material hardening the authors verify Halphen's Theorem which states that a structure made of material with kinematic hardening behavior and constant properties with temperature will always shake down to a periodic behavior.

    Full Text Available In Vietnam, many government announcements have gathered negative receptions from the public. Among them, Ms. Nguyen Thi Kim Tien, Vietnam Minister of Health, has received more of it. Through the case study of Ms. Kim Tien’s many scandals during the 2013-2014 period, this study is interested to see if the health scandals eventually elevated into a government crisis, how they affected the minister’s reputation, and what she could have done to better respond to the public. This study examined news articles on such health scandals to confirm whether the health scandals indeed escalated to be a government crisis. It also identified the advantages and disadvantages of Ms. Kim Tien’s responses in restoring her reputation to the public to understand what factors contributed to public dissatisfaction toward the minister. This study concluded that poorly-managed health scandals eventually elevated into a government crisis and greatly affected the minister’s reputation. It is suggested that PR is what the government needs to deal with such situations. The research also leaves room for a quantitative approach to the case to increase the result’s validity and representativeness. Until now, as the health issues and the resignation appeals are still needed, the crisis management effort should get more attention from the government, and such study is needed to better understand the situation.

  2. Measurement device-independent quantum dialogue

    Very recently, the experimental demonstration of quantum secure direct communication (QSDC) with state-of-the-art atomic quantum memory has been reported (Zhang et al. in Phys Rev Lett 118:220501, 2017). Quantum dialogue (QD) falls under QSDC where the secrete messages are communicated simultaneously between two legitimate parties. The successful experimental demonstration of QSDC opens up the possibilities for practical implementation of QD protocols. Thus, it is necessary to analyze the practical security issues of QD protocols for future implementation. Since the very first proposal for QD by Nguyen (Phys Lett A 328:6-10, 2004), a large number of variants and extensions have been presented till date. However, all of those leak half of the secret bits to the adversary through classical communications of the measurement results. In this direction, motivated by the idea of Lo et al. (Phys Rev Lett 108:130503, 2012), we propose a measurement device-independent quantum dialogue scheme which is resistant to such information leakage as well as side-channel attacks. In the proposed protocol, Alice and Bob, two legitimate parties, are allowed to prepare the states only. The states are measured by an untrusted third party who may himself behave as an adversary. We show that our protocol is secure under this adversarial model. The current protocol does not require any quantum memory, and thus, it is inherently robust against memory attacks. Such robustness might not be guaranteed in the QSDC protocol with quantum memory (Zhang et al. 2017).

    Background: Initialization of tropical cyclones in numerical weather prediction (NWP) systems is a great challenge: Mass-wind ?eld balance; Secondary circulation and heating; Asymmetries. There can be large adjustments in structure and intensity in the ?rst 24 hours if the initial vortex is not in balance: Spurious gravity waves; Spin-up (model and physics). Existing mesoscale NWP model TC (Tropical Cyclone) initialization strategies: Bogus vortex, cold start from global analyses; 3DVAR or 4DVAR, possibly with synthetic observations; EnKF (Ensemble Kalman Filter); Dynamic initialization. Dynamic initialization allows vortex to have improved balance and physics spin-up at the initial time (e.g., Hendricks et al. 2013, 2011; Nguyen and Chen 2011; Fiorino and Warner 1981; Hoke and Anthes 1976). Himawari-8 geostationary satellite has capability of continuous imagery (10-minutes) over the full disk: New GOES-R satellites will have same capability. This will allow for unprecedented observations of tropical cyclones. However, current data assimila1on systems are not capable of ingesting such high temporal observations (Atmospheric Mo1on Vectors - AMVs). Hourly AMVs are produced, and thinned to 100-kilometer spacing in the horizontal. An entirely new data assimilation concept is required to utilize these observations.

    Density functional theory (DFT) calculations show that self-interstitial atom (SIA) defects in nonmagnetic body-centered-cubic (bcc) metals adopt strongly anisotropic configurations, elongated in the direction [S. Han et al., Phys. Rev. B 66, 220101 (2002), 10.1103/PhysRevB.66.220101; D. Nguyen-Manh et al., Phys. Rev. B 73, 020101 (2006), 10.1103/PhysRevB.73.020101; P. M. Derlet et al., Phys. Rev. B 76, 054107 (2007), 10.1103/PhysRevB.76.054107; S. L. Dudarev, Annu. Rev. Mater. Res. 43, 35 (2013), 10.1146/annurev-matsci-071312-121626]. Elastic distortions, associated with such anisotropic atomic structures, appear similar to distortions around small prismatic dislocation loops, although the extent of this similarity has never been quantified. We derive analytical formulas for the dipole tensors of SIA defects, which show that, in addition to the prismatic dislocation looplike character, the elastic field of a SIA defect also has a significant isotropic dilatation component. Using empirical potentials and DFT calculations, we parametrize dipole tensors of defects for all the nonmagnetic bcc transition metals. This enables a quantitative evaluation of the energy of elastic interaction between the defects, which also shows that in a periodic three-dimensional simple cubic arrangement of crowdions, long-range elastic interactions between a defect and all its images favor a orientation of the defect.

  7. Conduction gap in graphene strain junctions: direction dependence

    Nguyen, M Chung; Nguyen, V Hung; Dollfus, P; Nguyen, Huy-Viet

    2014-01-01

    It has been shown in a recent study (Nguyen et al 2014 Nanotechnology 25 165201) that unstrained/strained graphene junctions are promising candidates to improve the performance of graphene transistors which is usually hindered by the gapless nature of graphene. Although the energy bandgap of strained graphene still remains zero, the shift of Dirac points in the k-space due to strain-induced deformation of graphene lattice can lead to the appearance of a finite conduction gap of several hundred meV in strained junctions with a strain of only a few per cent. However, since it depends essentially on the magnitude of the Dirac point shift, this conduction gap strongly depends on the direction of applied strain and the transport direction. In this work, a systematic study of conduction-gap properties with respect to these quantities is presented and the results are carefully analyzed. Our study provides useful information for further investigations to exploit graphene-strained junctions in electronic applications and strain sensors. (paper)

    Amorphous polymers exhibit a rich landscape of time-dependent behavior including viscoelasticity, structural relaxation, and viscoplasticity. These time-dependent mechanisms can be exploited to achieve shape-memory behavior, which allows the material to store a programmed deformed shape indefinitely and to recover entirely the undeformed shape in response to specific environmental stimulus. The shape-memory performance of amorphous polymers depends on the coordination of multiple physical mechanisms, and considerable opportunities exist to tailor the polymer structure and shape-memory programming procedure to achieve the desired performance. The goal of this project was to use a combination of theoretical, numerical and experimental methods to investigate the effect of shape memory programming, thermo-mechanical properties, and physical and environmental aging on the shape memory performance. Physical and environmental aging occurs during storage and through exposure to solvents, such as water, and can significantly alter the viscoelastic behavior and shape memory behavior of amorphous polymers. This project – executed primarily by Professor Thao Nguyen and Graduate Student Rui Xiao at Johns Hopkins University in support of a DOE/NNSA Presidential Early Career Award in Science and Engineering (PECASE) – developed a theoretical framework for chemothermo- mechanical behavior of amorphous polymers to model the effects of physical aging and solvent-induced environmental factors on their thermoviscoelastic behavior.

Imaging tools with near-histological precision have enhanced our knowledge about pathophysiological mechanisms that play a role in vision loss due to AMD. Visual, social, and vocational rehabilitation are all important treatment goals. In this review, evidence from landmark clinical trials is summarized to elucidate the optimum modern-day management of neovascular AMD. Therapeutic strategies currently under development, such as gene therapy and personalized medicine, are also described. Keywords: AMD, neovascular AMD, choroidal neovascular membrane, pharmacogenomics, VEGF, low-vision rehabilitation, gene therapy

  10. The right to fashion in the age of terrorism.

    As part of a feminist commitment to collaboration, this article appears as a companion essay to Mimi Thi Nguyen's "The Biopower of Beauty: Humanitarian Imperialisms and Global Feminisms" and offers a point of departure for thinking about fashion and beauty as processes that produce subjects recruited to, and aligned with, the national interests of the United States in the war on terror. The Muslim woman in the veil and her imagined opposite in the fashionably modern - and implicitly Western - woman become convenient metaphors for articulating geopolitical contests of power as a human rights concern, as a rescue mission, as a beautifying mandate. This article examines newer iterations of this opposition, in the wake of September 11, 2001, in order to demonstrate the critical resonance of a biopolitics on fashion and beauty. In "The Right to Fashion in the Age of Terrorism," the author examines the relationship between the U.S. war on terror, targeting persons whose sartorial choices are described as terrorist-looking and oppressive, and the right-to-fashion discourse, which promotes fashion's mass-market diffusion as a civil liberty. Looking at these multiple invocations of the democratization of fashion, this article argues that the right-to-fashion discourse colludes with the war on terror by fabricating a neoliberal consumer-citizen who is also a couture-citizen and whose right to fashion reasserts U.S.exceptionalism, which is secured by private property, social mobility, and individualism.

    A Time-Dependent Configuration Interaction approach using multiple Feshbach partitionings, corresponding to multiple ionization stages of a laser-driven molecule, has recently been proposed [T.-T. Nguyen-Dang and J. Viau-Trudel, J. Chem. Phys. 139, 244102 (2013)]. To complete this development toward a fully ab-initio method for the calculation of time-dependent electronic wavefunctions of an N-electron molecule, we describe how tools of multiconfiguration quantum chemistry such as the management of the configuration expansion space using Graphical Unitary Group Approach concepts can be profitably adapted to the new context, that of time-resolved electronic dynamics, as opposed to stationary electronic structure. The method is applied to calculate the detailed, sub-cycle electronic dynamics of BeH 2 , treated in a 3–21G bound-orbital basis augmented by a set of orthogonalized plane-waves representing continuum-type orbitals, including its ionization under an intense λ = 800 nm or λ = 80 nm continuous-wave laser field. The dynamics is strongly non-linear at the field-intensity considered (I ≃ 10 15 W/cm 2 ), featuring important ionization of an inner-shell electron and strong post-ionization bound-electron dynamics

    How are publics of protection and care defined in African cities today? The effects of globalization and neo-liberal policies on urban space are well documented. From London to São Paulo, denationalization, privatization, offshoring and cuts in state expenditure are creating enclaves and exclusions, resulting in fragmented, stratified social geographies (see Caldeira 2000; Ong 2006; Harvey 2006; Murray 2011). 'Networked archipelagoes', islands connected by transnational circulations of capital, displace other spatial relations and imaginaries. Spaces of encompassment, especially, such as 'the nation' or simply 'society' as defined by inclusion within a whole, lose practical value and intellectual purchase as referents of citizenship (Gupta and Ferguson 2002; Ferguson 2005). In African cities, where humanitarian, experimental or market logics dominate the distribution of sanitation and healthcare, this fragmentation is particularly stark (see, for example, Redfield 2006, 2012; Fassin 2007; Bredeloup et al . 2008; Nguyen 2012). Privilege and crisis interrupt older contiguities, delineating spaces and times of exception. The 'public' of health is defined by survival or consumption, obscuring the human as bearer of civic rights and responsibilities, as inhabitants of 'objective' material worlds 'common to all of us' (Arendt 1958: 52). Is it possible, under these conditions, to enact and imagine public health as a project of citizens, animated in civic space?

    Full Text Available Dysferlinopathy is an uncommon, progressive muscular dystrophy that has a wide phenotypic variability and primarily supportive management (Nguyen et al., 2007; Narayanaswami et al., 2014. Amyloid myopathy is a distinct, rare disorder that can present similarly to inflammatory myopathies and requires a high clinical suspicion for early intervention to prolong survival. Amyloid myopathy is typically associated with other systemic manifestations of amyloidosis, but rare cases of isolated amyloid myopathy have been described (Mandl et al., 2000; Hull et al., 2001. Positive Congo red stains on tissue biopsy remain the gold standard for diagnosis (Spuler et al., 1998; Karacostas et al., 2005. A high clinical suspicion and meticulous diagnostic workup that includes novel techniques are necessary for identifying these rare disorders. We report a middle-aged man with progressive leg muscle weakness who was initially treated as having amyloid myopathy but was later diagnosed as having dysferlinopathy by Whole Exome Sequencing (WES analysis. We also report a novel missense mutation (c.959G>C to help correlate in any patient with presumed dysferlinopathy and to add to the already known genotype of this disorder.

    STEM education; the encompassment of the four fields including science, technology, engineering, and mathematics; is introduced to provide students with chances to confront and solve real world problems and situations. Literature has evidence that this approach has positive impacts on students' learning motivation, learning engagement, learning achievements, and participation in STEM subjects and careers. This further lead to assurance of enough qualified STEM staffs for cross economic and mixed cultural working environment of the 21st century world. Our paper explores STEM factors underneath what is considered as traditional ways of teaching in a specific subject in pre-service teacher curriculum at Physics Faculty, Thai Nguyen University of Education, Vietnam. Data of the research were collected from a variety of sources including field notes, observation notes, analyzing of the course syllabus and students' final products. Data were analyzed based on the STS approach and SWOT analysis. The research reveals different kinds of STEM factors and manifestations that has been organized and introduced to the students. The research implications propose further research and directions to take the available advantages to benefit and ease the integration of STEM programs into specific educational context in Vietnam.

    Riparian areas are the terrestrial environment adjacent to water that both influences and is influenced by the aquatic feature (Gregory et al., 1991; Naiman et al., 2010). Riparian areas along streams provide shade, sources of wood and organic matter, contribute to bank stability, filter sediments, take up excess nutrients from groundwater inputs, and other key processes that protect freshwaters (e.g. Naiman et al., 2010; Richardson & Danehy, 2007; Figure 9.1). Riparian areas also increase biodiversity through habitat complexity and close juxtaposition of aquatic and terrestrial environments (Quinn et al., 2004; Naiman et al., 2010). Alterations to riparian areas, despite their small area relative to the landscape, have disproportionate effects on habitats and fish communities (Naiman et al., 2010; Wipfli & Baxter, 2010). Key habitat losses and alterations are derived from modification of riparian areas by reducing instream habitat complexity (Bilby & Ward, 1989; Fausch & Northcote, 1992; Naiman et al., 2010), diminishing the productive basis of freshwater food webs (Belsky et al., 1999; Quinn et al., 2004), increasing nutrient, contaminant and sediment intrusion (Muscutt et al., 1993; Daniels & Gilliam, 1996; Nguyen et al., 1998; Waters, 1999).

Among these many modes of failure, bacterial infection at the site of implantation has become a greater concern with the rise of antibiotic-resistant bacteria. Nanostructured surfaces have been found to prevent bacterial colonization on many surfaces, including nanotextured titanium. In many cases, specific nanoscale roughness values and resulting surface energies have been considered to be “bactericidal”; here, we explore the use of ion beam evaporation as a novel technique to create nanoscale topographical features that can reduce bacterial density. Specifically, we investigated the relationship between the roughness and titanium nanofeature shapes and sizes, in which smaller, more regularly spaced nanofeatures (specifically 40–50 nm tall peaks spaced ~0.25 µm apart were found to have more effect than surfaces with high roughness values alone.

Measures of dynamic lower extremity valgus have been previously shown to relate to increased risk of several knee pathologies, specifically anterior cruciate ligament ruptures and patellofemoral pain. Therefore, hip-focused interventions have gained considerable attention and been successful in addressing these knee pathologies. The purpose of the review was to identify and discuss hip-focused exercise interventions that aim to address dynamic lower extremity valgus. Previous electromyography, kinematics, and kinetics research support the use of targeted hip exercises with non-weight-bearing, controlled weight-bearing, functional exercise, and, to a lesser extent, dynamic exercises in reducing dynamic lower extremity valgus. Further studies should be developed to identify and understand the mechanistic relationship between optimized biomechanics during sports and hip-focused neuromuscular exercise interventions.Keywords: dynamic lower extremity valgus, hip neuromuscular control, ACL injury rehabilitation, patellofemoral pain, hip muscular activation

    Elliot Ahumada, Esosa Oghogho, Samantha Nguyen, Humberto Bracho, Diego Quintero, Ashanti Johnson and Kevin Cuff Lake Merritt is a tidal lagoon in the center of Oakland, California, just east of Downtown. Water quality at Lake Merritt has been a major concern for community members and researchers for many years (Pham 200X). Results of past research lead to recommendations to lengthen a channel that connects Lake Merritt with the San Francisco Bay to improve water flow and quality. In 2012 the City of Oakland responded to these recommendations by initiating the creation of a 230-meter long channel. In conducting our research we use a water quality index that takes into account measurements of pH, temperature, water hardness (dissolved solids), ammonia, salinity, dissolved oxygen, and nitrate. Newly collected data is then compared with that collected by Pham using comparable parameters to assess the impact of recent changes at the Lake on its overall water quality. In addition, we measured the abundance of aquatic species at four different sites within the Lake. Preliminary results suggest that an increase in the abundance of fish and improved overall water quality have resulted from channel extension at Lake Merritt.

    Choked flow calculation is improved by using a new sound speed criterion for bubbly flow that is derived by the characteristic analysis of hyperbolic two-fluid model. This model was based on the notion of surface tension for the interfacial pressure jump terms in the momentum equations. Real eigenvalues obtained as the closed-form solution of characteristic polynomial represent the sound speed in the bubbly flow regime that agrees well with the existing experimental data. The present sound speed shows more reasonable result in the extreme case than the Nguyens did. The present choked flow criterion derived by the present sound speed is employed in the MARS code and assessed by using the Marviken choked flow tests. The assessment results without any adjustment made by some discharge coefficients demonstrate more accurate predictions of choked flow rate in the bubbly flow regime than those of the earlier choked flow calculations. By calculating the Typical PWR (SBLOCA) problem, we make sure that the present model can reproduce the reasonable transients of integral reactor system

    A number of melting curves of various materials have recently been measured experimentally and calculated theoretically, but the agreement between different groups is not always good. We discuss here some of the problems which may arise in both experiments and theory. We also report the melting curves of Fe and Al calculated recently using quantum mechanics techniques, based on density functional theory with generalized gradient approximations. For Al our results are in very good agreement with both low pressure diamond-anvil-cell experiments (Boehler and Ross 1997 Earth Planet. Sci. Lett. 153 223, Haenstroem and Lazor 2000 J. Alloys Compounds 305 209) and high pressure shock wave experiments (Shaner et al 1984 High Pressure in Science and Technology ed Homan et al (Amsterdam: North-Holland) p 137). For Fe our results agree with the shock wave experiments of Brown and McQueen (1986 J. Geophys. Res. 91 7485) and Nguyen and Holmes (2000 AIP Shock Compression of Condensed Matter 505 81) and the recent diamond-anvil-cell experiments of Shen et al (1998 Geophys. Res. Lett. 25 373). Our results are at variance with the recent calculations of Laio et al (2000 Science 287 1027) and, to a lesser extent, with the calculations of Belonoshko et al (2000 Phys. Rev. Lett. 84 3638). The reasons for these disagreements are discussed

    Bhatti and Nguyen (2012) used the copula approach to measure the tail dependence between a number of international markets. They observed that some country pairs exhibit only left-tail dependence whereas others show only right-tail. However, the flow of information from uni-dimensional (one-tail) to bi-dimensional (two-tails) between various markets was not accounted for. In this study, we address the flow of information of this nature by using the dynamic conditional correlation (DCC-GARCH) model. More specifically, we use various versions of the DCC models to explain the nexus between the information flow of international equity and to explain the stochastic forward vs. backward dynamics of financial markets based on data for a 15-year period comprising 3,782 observations. We observed that the information flow between the US and Hong Kong markets and between the US and Australian markets are bi-directional. We also observed that the DCC model captures a wider co-movement structure and inter-connectedness compared to the symmetric Joe-Clayton copula.

    Recently, Bhatti and Nguyen (2012) used EVT and various stochastic copulas to study the cross-country co-movements diversification and asset pricing allocation. Weiss (2013) observed that Dynamic Conditional Correlation (DCC) models outperform various copula models. This paper attempts to contribute to the literature on multivariate models for capturing forward and backward return co-movement, spillover effects and volatility linkages. It reflects cross-country forward and backward co-movements more clearly among various coupled international stock markets relating to information transmission and price discovery for making investment decisions. Given the reality of fat-tail or skewed distribution of financial data, this paper proposes the use of VECM-DCC and VAR-DCC models which capture dynamic dependences between the Australian and other selected international financial stock markets. We observe that the return co-movement effects between Australian and Asian countries are bidirectional ((AUS ↔ Hong Kong), (AUS ↔ Japan)) with the exception of Taiwan (AUS → Taiwan). We also observe that the volatility spillover between the Australian and both the UK and the US markets are bidirectional with a larger volatility spillover from both toward the AUS market. Further, the UK market has a higher volatility spillover on the Australian market compared to the US market and the US market has a higher volatility spillover on the UK than that of the Australian market.

    Fanconi anemia is a rare genetic disorder that can lead to bone marrow failure, congenital abnormalities, and increased risk for leukemia and cancer. Cells with loss-of-function mutations in the FANC pathway are characterized by chromosome fragility, altered mutability, and abnormal regulation of the nonhomologous end-joining (NHEJ) pathway. Somatic hypermutation (SHM) and immunoglobulin (Ig) class switch recombination (CSR) enable B cells to produce high-affinity antibodies of various isotypes. Both processes are initiated after the generation of dG:dU mismatches by activation-induced cytidine deaminase. Whereas SHM involves an error-prone repair process that introduces novel point mutations into the Ig gene, the mismatches generated during CSR are processed to create double-stranded breaks (DSBs) in DNA, which are then repaired by the NHEJ pathway. As several lines of evidence suggest a possible role for the FANC pathway in SHM and CSR, we analyzed both processes in B cells derived from Fanca(-/-) mice. Here we show that Fanca is required for the induction of transition mutations at A/T residues during SHM and that despite globally normal CSR function in splenic B cells, Fanca is required during CSR to stabilize duplexes between pairs of short microhomology regions, thereby impeding short-range recombination downstream of DSB formation. © 2014 Nguyen et al.

    Full Text Available This paper addresses the multiobjective discrete network design problem under demand uncertainty. The OD travel demands are supposed to be random variables with the given probability distribution. The problem is formulated as a bilevel stochastic optimization model where the decision maker’s objective is to minimize the construction cost, the expectation, and the standard deviation of total travel time simultaneously and the user’s route choice is described using user equilibrium model on the improved network under all scenarios of uncertain demand. The proposed model generates globally near-optimal Pareto solutions for network configurations based on the Monte Carlo simulation and nondominated sorting genetic algorithms II. Numerical experiments implemented on Nguyen-Dupuis test network show trade-offs among construction cost, the expectation, and standard deviation of total travel time under uncertainty are obvious. Investment on transportation facilities is an efficient method to improve the network performance and reduce risk under demand uncertainty, but it has an obvious marginal decreasing effect.

    All welding processes induce deformations and thermal tensions, which must be evaluated correctly since they can influence a component's structural integrity. This work determines the distribution of temperatures that develop during a manual welding process with shielded electrodes (SMAW), on the circumference seam of a pipe for use in polyducts. A simplified model of Finite Elements (FEA) using three dimensional solids is proposed for the study. The analysis considers that while the welding process is underway, no heat is lost into the environment, that is, adiabatic conditions are considered, and the transformations produced in the material due to phase changes do not produce modifications in the properties of the supporting or base materials. The results of the simulation are compared with those obtained by recent analytical studies developed by different investigators, such as Nguyen, Ohta, Matsuoka, Suzuki and Taeda, where a continuously moving three dimensional double ellipsoidal source was used. The results are then compared with the experimental results by measuring with thermocouples. This study reveals the sensitivity and the validity of the proposed computer model, and in a second stage optimizes the engineering times for the resolution of a problem like the one presented in order to design the corresponding welding procedure (CW)

    In this talk several important advances in the field of Organic Spintronics and magnetic field effect (MFE) of organic films and optoelectronic devices that have occurred during the past two years from the Utah group will be surveyed and discussed. (i) Organic Spintronics: We demonstrated spin organic light emitting diode (spin-OLED) using two FM injecting electrodes, where the electroluminescence depends on the mutual orientation of the electrode magnetization directions. This development has opened up research studies into organic spin-valves (OSV) in the space-charge limited current regime. (ii) Magnetic field effect: We demonstrated that the photoinduced absorption spectrum in organic films (where current is not involved) show pronounced MFE. This unravels the underlying mechanism of the MFE in organic devices, to be more in agreement with the field of MFE in Biochemistry. (iii) Spin effects in organic optoelectronic devices: We demonstrated that certain spin 1/2 radical additives to donor-acceptor blends substantially enhance the power conversion efficiency of organic photovoltaic (OPV) solar cells. This effect shows that studies of spin response and MFE in OPV devices are promising. In collaboration with T. Nguyen, E. Ehrenfreund, B. Gautam, Y. Zhang and T. Basel.

    2018-05-01

    Optimal partial mass transport, which is a variant of the optimal transport problem, consists in transporting effectively a prescribed amount of mass from a source to a target. The problem was first studied by Caffarelli and McCann (2010) [6] and Figalli (2010) [12] with a particular attention to the quadratic cost. Our aim here is to study the optimal partial mass transport problem with Finsler distance costs including the Monge cost given by the Euclidian distance. Our approach is different and our results do not follow from previous works. Among our results, we introduce a PDE of Monge-Kantorovich type with a double obstacle to characterize active submeasures, Kantorovich potential and optimal flow for the optimal partial transport problem. This new PDE enables us to study the uniqueness and monotonicity results for the active submeasures. Another interesting issue of our approach is its convenience for numerical analysis and computations that we develop in a separate paper [14] (Igbida and Nguyen, 2018).

    Large-region acoustic source mapping is important for city-scale noise monitoring. Approaches using a single-position measurement scheme to scan large regions using small arrays cannot provide clean acoustic source maps, while deploying large arrays spanning the entire region of interest is prohibitively expensive. A multiple-position measurement scheme is applied to scan large regions at multiple spatial positions using a movable array of small size. Based on the multiple-position measurement scheme, a sparse-constrained multiple-position vectorized covariance matrix fitting approach is presented. In the proposed approach, the overall sample covariance matrix of the incoherent virtual array is first estimated using the multiple-position array data and then vectorized using the Khatri-Rao (KR) product. A linear model is then constructed for fitting the vectorized covariance matrix and a sparse-constrained reconstruction algorithm is proposed for recovering source powers from the model. The user parameter settings are discussed. The proposed approach is tested on a 30 m × 40 m region and a 60 m × 40 m region using simulated and measured data. Much cleaner acoustic source maps and lower sound pressure level errors are obtained compared to the beamforming approaches and the previous sparse approach [Zhao, Tuna, Nguyen, and Jones, Proc. IEEE Intl. Conf. on Acoustics, Speech and Signal Processing (ICASSP) (2016)].

    Full Text Available We simulate the pathophysiology of severe burn trauma and burn-induced sepsis, using rat models of experimental burn injury and cecal ligation and puncture (CLP either individually (singe-hit model or in combination (double-hit model. The experimental burn injury simulates a systemic but sterile pro-inflammatory response, while the CLP simulates the effect of polymicrobial sepsis. Given the liver׳s central role in mediating the host immune response and onset of hypermetabolism after burn injury, elucidating the alterations in hepatic gene expression in response to injury can lead to a better understanding of the regulation of the inflammatory response, whereas circulating cytokine protein expression, reflects key systemic inflammatory mediators. In this article, we present both the hepatic gene expression and circulating cytokine/chemokine protein expression data for the above-mentioned experimental model to gain insights into the temporal dynamics of the inflammatory and hypermetabolic response following burn and septic injury. This data article supports results discussed in research articles (Yang et al., 2012 [1,4]; Mattick et al. 2012, 2013 [2,3]; Nguyen et al., 2014 [5]; Orman et al., 2011, 2012 [6–8].

    The status of mood-congruent free recall bias in anxious individuals was evaluated following incidental encoding of target words. Individuals with high and low levels of trait anxiety completed a modified Stroop task, which revealed an attentional bias for threat-related stimuli in anxious individuals. This group was significantly slower in naming the colour in which threat-related words were displayed compared to neutral words. In a subsequent free recall test for the words used in the modified Stroop task, anxious individuals recalled more threat-related words compared to low-anxious people. This difference was significant even when controlling for the false recall of items that had not been presented during study. These results support the view put forward by Russo, Fox, Bellinger, and Nguyen-Van-Tam (2001) that mood-congruent free recall bias in anxious individuals can be observed if the target material is encoded at a relatively shallow level. Moreover, contrary to Dowens and Calvo (2003), the current results show that the memory advantage for threat-related information in anxious individuals is not a consequence of response bias.

    Non-indigenous invasive mole crickets, Scapteriscus vicinus Scudder (Orthoptera: Gryllotalpidae) in Florida and S. didactylus (Latreille) (the 'changa') in Puerto Rico, are being managed with an entomopathogenic nematode, Steinernema scapterisci (Nguyen and Smart) (Rhabditida: Steinernematidae), and a parasitic wasp, Larra bicolor L. (Hymenoptera: Sphecidae). Pest mole cricket populations have declined by 95% in north central Florida since these specialist natural enemies were released and established in the 1980s. Commercial production of the nematode was initiated, nearly 70 billion were applied in 34 Florida counties, and their establishment, spread, and impact on mole crickets were monitored. The infected mole crickets dispersed the nematode rapidly, so that within 6 months these parasites were present in most of the insects trapped in experimental pastures. Three years later, mole cricket populations were reduced to acceptable levels and the bahiagrass had recovered. The nematode was released for the first time in Puerto Rico during 2001 and has persisted; the wasp was introduced in the late 1930s. The geographical distribution of the wasp is being expanded in Florida and Puerto Rico by planting plots of Spermacoce verticillata (L.), a wildflower indigenous to Puerto Rico and widely distributed in southern Florida. Pastures, sod farms, golf courses, landscapes, and vegetable farms in Florida and Puerto Rico are benefiting from biological control of invasive mole crickets. (author) [es

    Support from social network members may help to facilitate access to HIV medical care, especially in low resourced communities. As part of a randomized clinical trial of a community-level stigma and risk reduction intervention in Thai Nguyen, Vietnam for people living with HIV who inject drugs (PWID), 341 participants were administered a baseline social network inventory. Network predictors of antiretroviral therapy (ART) initiation at the 6-month follow-up were assessed. The social networks of PWID were sparse. Few participants who reported injectors in their networks also reported family members, whereas those who did not have injectors were more likely to report family members and network members providing emotional support and medical advice. In multivariate models, having at least one network member who provided medical advice predicted ART initiation at 6 months (OR 2.74, CI 1.20-6.28). These results suggest the importance of functional social support and network support mobilization for ART initiation among PWID.

    There is a global need to develop low-cost technologies to remove arsenic from water for individual household water supply. In this study, a purified and enriched waste material (treated magnetite waste, TMW) from the Trai Cau's iron ore mine in the Thai Nguyen Province in Vietnam was examined for its capacity to remove arsenic. The treatment system was packed with TMW that consisted of 75% of ferrous-ferric oxide (Fe(3)O(4)) and had a large surface area of 89.7 m(2)/g. The experiments were conducted at a filtration rate of 0.05 m/h to treat groundwater with an arsenic concentration of 380 microg/L and iron, manganese and phosphate concentrations of 2.07 mg/L, 0.093 mg/L and 1.6 mg/L respectively. The batch experimental results show that this new material was able to absorb up to 0.74 mg arsenic/g. The results also indicated that the treatment system removed more than 90% arsenic giving an effluent with an arsenic concentration of less than 30 microg/L while achieving a removal efficiency of about 80% for Mn(2 + ) and PO(4) (3-). This could be a promising and cost-effective new material for capturing arsenic as well as other metals from groundwater.

    To evaluate the association between the single nucleotide polymorphism (SNP) rs227493 in the MEOX2 gene and nonsyndromic cleft palate only, this research was conducted as a case-control study by comparing a nonsyndromic cleft palate only group with an independent, healthy, and unaffected control group who were both examined by specialists. Based on clinical examination and medical records, we analyzed a total of 570 DNA samples, including 277 cases and 293 controls, which were extracted from dry blood spot samples collected from both the Odonto and Maxillofacial Hospital in Ho Chi Minh City and Nguyen Dinh Chieu Hospital in Ben Tre province, respectively. The standard procedures of genotyping the specific SNP (rs2237493) for MEOX2 were performed on a StepOne Realtime PCR system with TaqMan SNP Genotyping Assays. Significant statistical differences were observed in allelic frequencies (allele T and allele G) between the non-syndromic cleft palate only and control groups in female subjects, with an allelic odds ratio of 1.455 (95% confidence interval: 1.026-2.064) and P < 0.05. These study findings suggest that nonsyndromic isolated cleft palate might be influenced by variation of MEOX2, especially SNP rs2237493 in Vietnamese females. © 2017 Japanese Teratology Society.

    Full Text Available Developmental dysplasia of the hip (DDH is the most common congenital deformation of the musculoskeletal system and its successful treatment is closely related to early diagnosis. The study is aimed at examining the incidence of developmental dysplasia of the hip (DDH and at analysing the validity of clinical examination, which is used for the early detection of DDH in the neonatal period, compared to ultrasound examination.The study involved 400 neonates born in the Banja Luka Region. A new questionnaire was open during the first regular ultrasound and clinical examination of the neonates’ hips and anamnestic and clinical data were recorded in it: the asymmetry of the gluteal, inguinal and femoral folds (Bade sign, the result of abduction testseparately for each hip, the Ortolani sign of luxation and the Palmen sign of reposition, then hip sonography. A Toshiba ultrasound machine with a 7.5 MHz linear probe was used. The method employed was Professor Reinhard Graf’s. Out of the total number of the children with a positive sonographic finding for DDH, 63.16% of them have one of the clinical signs of DDH. The ability of a clinical finding to identify those patients who do not have DDH and have a negative sonographic finding is 79.8%. Out of the total number of the examined children with a positive clinical finding, only 15.58% of them also have a positive sonographic finding for DDH. This research has showed that clinical examination of the hips is of low sensitivity, specificity and reliability, and that not all types of DDH can be detected. Clinical examination must remain an integral part of every infant’s examination, but it constitutes a complementary diagnostic procedure to ultrasound examination. The ultrasound examination of DDH has created new possibilities and has filled the void that existed due to the deficiency of clinical tests, and at the same time it has reduced the number of X-ray examinations of the hips. This research has

    Full Text Available Reinhard ReussDepartment of Neurology, BKH Bayreuth, Bayreuth, GermanyAbstract: Current standard immunomodulatory therapy with interferons (IFNs for relapsing–remitting multiple sclerosis (MS exhibits proven, but limited, efficacy and increased side effects due to the need of frequent application of the drug. Therefore, there is a need for more effective and tolerable drugs. Due to their small size, optimization of therapy with IFNs in MS by PEGylation is feasible. PEGylation of an IFN means that at least one molecule of polyethylene glycol (PEG is covalently added. This modification is a standard procedure to increase the stability, solubility, half-life, and efficacy of a drug, and is applied in several drugs and diseases. Currently, a therapy regimen applying PEG-IFN beta-1a in MS is being developed to achieve an optimized relationship between therapy-related side effects and pharmacokinetic/pharmacodynamic efficacy. Phase I studies demonstrated that subcutaneous PEG-IFN beta-1a at a dose of 125 µg every 2 or 4 weeks might be at least as efficient and safe as the current standard therapy with IFN beta-1a. A global Phase III clinical study is investigating the efficacy of PEG-IFN beta-1a in terms of reduction of the relapse rate in relapsing–remitting MS patients. The latest primary safety and efficacy analysis after 1 year has revealed a favorable risk–benefit profile with no significant difference between dosing regimens. Compared to placebo, the annualized relapse rate was reduced by about one-third and new or newly enlarging T2 brain lesions were reduced by about one-third when dosing every 4 weeks or by two-thirds when dosing every 2 weeks. This presents a significant effect of the dosing interval, favoring administration every 2 weeks. Chronic administration of PEGylated proteins mostly at toxic concentrations causes vacuolation of renal epithelium in animals, which – along with the issue of occurrence of anti-PEG antibodies

    The momentum distribution (MD) of nucleons in a nucleus is an important issue ( for analyzing single-particle aspects of nuclear structure, for a review see [1]). One of the still open problems is the influence of global nuclear deformation on MD. There already exist some studies on that subject, see, e.g. [2,3] and references therein. Nonetheless, the present knowledge about deformation effects in MD is still rather poor, especially in heavy deformed nuclei. At the same time, these effects can be essential for a correct treatment of knock-out reactions, such as (e; e'p), in rare earth and actinide regions and for investigation of deep hole states in deformed nuclei (see, e.g., [4,5]). In our work we analyze momentum distributions of neutrons in odd plutonium isotopes at second minimum deformations in the framework of the phenomenological deformed Woods-Saxon potential. The shell correction and macroscopic part of the potential energy have been calculated via the Macroscopic-Microscopic formalism [6], considering as main deformation parameters ε (elongation) and α4 (hexadecapolar momentum) in Pashkevich's nuclear shape parametrization [6,7]. The parameters for the nuclear potential in the equilibrium deformations as well as in the second minimum were taken from a previous work [7]. References [1] A. N. Antonov, P. E. Hodgson and I. Zh.

    High energy heavy ion collisions have become one of the major growth areas of modern physics. Providing common ground between particle and nuclear physics, it has produced a wave of new interest and a series of major projects to provide beams of higher energies and increasing nuclear complexity. Reflecting this interest, and despite record rainstorms, over 450 enthusiastic high energy heavy ion followers met in Monterey, California, at the 11th International Conference on Ultra-relativistic Nucleus-Nucleus Collisions. Named Quark Matter '95, the meeting was characterized by its own flood of new results from experiments studying collisions of gold nuclei at the Brookhaven Alternating Gradient Synchrotron (AGS) and with silicon beams at the CERN SPS synchrotron, as well as preliminary results from the first run with lead beams at CERN late last year (December 1994, page 15). A striking aspect of the Conference was the growth in attendance and, in particular, the large number of young physicists who attended the meeting, underlining the vitality and appeal of this important field. The new preliminary data from CERN experiments NA44, NA49, NA52, WA97, and WA98, made available with remarkable speed following the initial lead beam run in November and December 1994, represent a significant step in the study of heavy ion collisions. Physicists have finally come close to conditions where it is possible to consider event-by-event analysis of these very complex final states. The importance of this emerging approach to relativistic heavy ion collisions was emphasized by Reinhard Stock (Frankfurt) and other speakers in a pre-conference workshop devoted to physics with the collider detectors at big new projects now in the pipeline - RHIC at Brookhaven and LHC at CERN. The study of collisions of heavy nuclei at relativistic energies is dominated by the search for the Quark-Gluon Plasma, the 'soup' of free quarks and gluons expected to have played an important role

  9. The K Dwarf Advantage for Biosignatures

    2018-01-01

    Biosignature detection is typically studied in the context of an atmosphere in chemical disequilibrium. Oxygen (O2) and methane (CH4) are generally considered the “canonical” biosignature disequilibrium pair. However, the modern CH4 concentration poses a major detection challenge to future direct imaging telescopes, and it has been difficult for Earth to accumulate spectrally detectable quantities of O2 and CH4 over its history (Olson et al 2016, Reinhard et al 2017). Even the lower atmospheric levels of O2 typical of the Earth’s Proterozoic eon (0.01-1% of the modern O2 amount) may have resulted in a reduced photochemical lifetime of CH4 due to decreased UV shielding of CH4 (Claire et al 2006, Goldblatt et al 2006). However, while the above is true for an Earthlike planet orbiting a sunlike star, the situation changes for other stars. For instance, Segura et al (2005) found longer photochemical lifetimes for CH4 in the atmospheres of Earthlike planets orbiting M dwarfs. M dwarfs, however, present several barriers to planetary habitability including desiccation during the stellar super-luminous pre-main sequence phase (Lugar and Barnes 2015) and tidal locking. K dwarfs, which comprise about 12% of all main sequence stars, avoid these M dwarf hazards, and will be important targets for future exoplanet direct imaging missions. Using a photochemical model, we find CH4 and O2 are simultaneously detectable in the atmospheres of K dwarf planets with various O2 concentrations ranging between Proterozoic levels and modern O2 amounts. For instance, for a planet with an Earth-like CH4 surface flux (1 x 1011 molecules/cm2/s) and a Proterozoic-like O2 level (1% of modern), the planet generates a CH4 surface mixing ratio of 1x10-5 for a planet orbiting the sun, and 1.5x10-4 – an order of magnitude more CH4 – for a planet orbiting a K6V star. This is enough to produce detectable CH4 and O2 for the planet orbiting the K6V star. We discuss the implications of this

    Full Text Available AbstractIn the wake of the recent university reforms, the new academic division of labor in Germany has subserviently followed the U.S.-model of creating a rift between research and teaching universities by establishing on the one hand so-called “elite universities” that benefit from considerable state funding and on the other hand trying to reduce the rest to pedagogical carbon copies of standard curricula that can only award bachelor‘s or at most master‘s degrees and where the teaching load allows (almost no research.The so-called “excellence initiative”, an evaluation process taking place between 2006 and 2007, in the course of which 9 universities  - among which the Free University of Berlin, the University of Munich, and the University of Heidelberg - were designated as “elite universities”, represents Germany‘s hitherto clearest and most highly institutionalized example of a state policy aimed at confining research to specialized institutions, such as was already the case with the Max Planck institutes, the Leibniz institutes and the Fraunhofer societies founded in the 1970s and 1980s.

The aorta and inferior vena cava were blocked at the level of the diaphragm and the upper arms were blocked by pneumatic cuffs. Chemotherapy, consisting of 60 mg/m² cisplatin and 15 mg/m² mitoxantrone, was administered directly into the aorta. The isolated circuit was maintained for 15 minutes followed by ~45 minutes of chemofiltration with a hemoprocessor until 5 L of filtrate were reached. The endpoints of the study were overall survival and quality of life (QoL.Results: Out of 28 patients enrolled in the study, 5 had prior surgeries, 10 patients had systemic chemotherapy, and 5 patients additional irradiation. In all patients in restaging, clinical progress was noted. In all, 162 cycles were administered. Due to chemofiltration, toxicity was within tolerable limits, revealing World Health Organization grade I leucopenia and thrombocytopenia in 9 patients and mucositis grade I in 6 patients. The major surgical complication was inguinal lymphatic fistula in 40% of the cases. Gastrointestinal toxicity and/or neurotoxicity were never observed. One-year survival was 49%, 2-year and 3-year survival was 31%, and 5

    Full Text Available The remarkable success of the Anglo-American legal system in establishing stable, democratic societies throughout the globe contrasts with the catastrophic failure, over the centuries, of the legal systems of continental Europe. Nevertheless, nationalistic sentiment in South Africa and Scotland reacted to increasing Common Law influence with a paradoxical idealisation of the Civil Law system. The various discourses of europäische Rechtsgeschichte behind the ideology are set in their historical and cultural contexts. The nationalistic discourse of Savigny, which reduced the whole of European legal history to a translatio studii of Roman law from Italy to France to Holland to German apotheosis, gave way in the wake of two world wars and the Holocaust to the new discourse of the ius commune, a legal paradigm for a future European Union based not on the historical reality of three centuries of religious, political and juridical conflict, but on a fantasy world of European legal unity from the beginning of the modern period until the 19th century national codifications. This was the post-war narrative of Helmut Coing, which, failing to anticipate the eclipse of the British Empire, steadfastly contrasted the shared legal tradition of continental Europe with the opposing system of the Anglo-American Common Law.With England now in the European Union the discourse has had to be modified. By exaggerating the importance of some minor and longrecognised continental influences on the Common Law, the contemporary discourse of the ius commune europaeum propagated by Reinhard Zimmermann succeeds in trumping the historical fantasy of a uniform continental legal past with the even more remote fantasy of a uniform continental and English legal culture. The old nationalist programme of a return to the 17th–18th century Roman-Dutch law, imbibed by Zimmermann as a law professor in Apartheid South Africa, can thus be presented as an appeal to the pan-European legal

  13. Aqueducts and geoglyphs : the response of Ancient Nasca to water shortages in the desert of Atacama (Peru)

    origin of Nasca religious belief based on the worship of the mountain gods, in charge of the rain, and, therefore, related to the worship of water and fertility, including rituals which took place inside and outside Cahuachi pyramids (Orefici 2012; Masini et al. 2008; 2009) and over the famous geoglyphs (Orefici 2009; Reinhard 1988) Therefore, the response of Nasca to make liveable the desert was twofold, aimed at addressing the problem in its causes (climate), by religion, ritual and ceremonial activities, and in its effects, through the construction of aqueducts. The paper deals with the results from 3-year scientific and interdisciplinary investigations conducted by ITACA Mission (Masini et al. 2012) in Peru of CNR-IBAM and IMAA, in the Rio Nasca drainage basin. The main purpose of the investigations was the study of lost and functioning aqueducts using active and passive satellite data along with spatial analysis and geophysics (Cigna et al. 2013: Tapete et al. 2013). In particular, multitemporal analyses of satellite data were carried out in order to identify the different moisture content from upper to lower valley and the seasonal changes from one to another year. Geoelectrical prospecting along with geological investigations enabled us to characterize the table water and to study the hydrogeology of the investigated area. Finally, GIS and spatial analyses provided new information on the relationship between the puquios , settlement patterns and geoglyphs. References Cigna F., Tapete D., Lasaponara R., Masini N. 2013.

    ACD algorithms were applied to the population, and concordance was examined using individual (i.e., sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) and overall performance measures (i.e., accuracy, Cohen's kappa coefficient, balanced accuracy, F-1 score, and phi coefficient). After applying the inclusion criteria, 7,490 patients were evaluated for statin intolerance. The mean (SD) age of the population was 51.1 (8.5) years, and 55.7% were male. The MP and ACD algorithms classified 11.3% and 5.4% of patients as having statin intolerance, respectively. The concordance of the MP algorithm was mixed, with negative classification of statin intolerance measures having high concordance (specificity 0.91, NPV 0.97) and positive classification of statin intolerance measures having poor concordance (sensitivity 0.45, PPV 0.21). Overall performance measures showed mixed agreement between the algorithms. Both algorithms used a mix of pharmacy and medical claims and may be useful for organizations interested in identifying patients with statin intolerance. By identifying patients with statin intolerance, organizations may consider a variety of options, including using nonstatin lipid-lowering therapies, to manage cardiovascular event risk in these patients.

Aims: We aimed to define patient and disease characteristics in a large group of adult and pediatric patients with KSS. Methods: We retrospectively searched the Mayo Clinic medical index patient database for the records of patients with KSS between 1976 and 2009. The 35 patients identified with KSS were analyzed in terms of demographic characteristics, presenting signs and symptoms, diagnostic features, clinical evolution, and associations between disease features and the development of disability. Results: The mean (standard [SD] age at KSS presentation was 17 (10 years, but the mean age at diagnosis was 26 (15 years. Ophthalmologic symptoms developed in all patients, and neurologic and cardiac involvement was common. Only four patients (11% in the series died, but all deaths were from sudden cardiac events. The development of physical disability was significantly associated with cognitive decline (P=0.004 but not with other clinical features, such as sex or sudden cardiac death. Conclusion: We report the largest case series to date of patients with KSS from a single institution. In addition to the conduction system abnormalities identified in previous series, our cohort included patients with syncope and sudden cardiac death. This underscores the need to consider formal electrophysiologic studies and prophylactic defibrillators in patients with KSS.

  19. Thin circular cylinder under axisymmetrical thermal and mechanical loading

    1977-01-01

    To assess structural integrity of components subjected to cyclic thermal loadings one must look at thermal ratchetting as a possible failure mode. Considering a thin circular cylinder subjected to constant internal pressure and cyclically varying thermal gradient through the thickness Bree, J. Strain Analysis 2 (1967) No.3, obtained a diagram that serves as a foundation for many design rules (e.g.: ASME code). The upper part of the french LMFBR main vessel is subjected to an axisymmetrical axial thermal loading and an axial load (own weight). Operation of the reactor leads to cyclic variations of the axial thermal loading. The question that arises is whether or not the Bree diagram is realistic for such loading conditions. A special purpose computer code (Ratch) was developed to analyse a thin circular cylinder subjected to axisymmetrical mechanical and thermal loadings. The Mendelson's approach of this problem is followed. Classical Kirchoff-Love hypothesis of thin shells is used and a state of plane stress is assumed. Space integrations are performed by Gaussian quadrature in the axial direction and by Simpson's one third rule throughout the thickness. Thermoelastic-plastic constitutive equations are solved with an implicit scheme (Nguyen). Thermovisco-plastic constitutive equations are solved with an explicit time integration scheme (Treanor's algorithm especially fitted). A Bree type diagram is obtained for an axial step of temperature which varies cyclically and a sustained constant axial load. The material behavior is assumed perfectly plastic and creep effect is not considered. Results show that the domain where no ratchetting occurs is reduced when compared with the domain predicted by the Bree diagram

    Full text: A wide variety of applications have been considered for superparamagnetic iron oxide nanoparticles (SPIONs), such as magnetic resonance imaging, cancer therapy and remediation of contaminants [1].Polymeric nanostructures (PNS) have also received great interest as suitable encapsulating agents and carriers due to their ability to influence the delivery profile. Hybrid nanosystems have been explored as a synergic approach that combines the modified active release induced by the polymer encapsulation and the intrinsic properties from the inorganic nanoparticles [2]. In this context, poly-ε-caprolactone nanocapsules containing different concentration of ∼8 nm superparamagnetic oleic acid coated magnetite (Fe{sub 3}O{sub 4}@OA) nanoparticles were developed. Successful incorporation of the magnetic nanoparticles was confirmed by transmission electron microscopy coupled with energy dispersive X-ray (TEM-EDX). Results showed that they accumulate preferentially in the outer organic membrane of the PNS. On the other hand, scanning electron microscopy and dynamic light scattering measurements showed a significant increase in particle size from ca. 400 to 800 nm. Magnetic measurements as a function of the applied magnetic field and temperature were performed in both vibrant sample (VSM) and superconducting quantum interference device magnetometers (SQUID). Hysteresis loops showed a superparamagnetic behavior with increasing saturation magnetization as magnetite concentration was progressively incorporated into the PNS. Zero-field cooled and field-cooled (ZFC-FC) magnetic curves showed a shift of the blocking temperature to higher temperatures as the content of magnetite increases in the capsules. These results are promising and contribute to a better understanding of the interaction between magnetic nanoparticles and PNS. References: [1] L. Zhang, W. Dong, H. Sun.

Four species, O. gracilis, O. riukiaria, O. avia and O. gigas, are confirmed as different from each other in gonopod characters, coloration and body size. The status of the last species, O. obtusus, is still doubtful and requires examination of further fresh material. The phylogenetic relationships among species of Oxidus is analyzed using two fragments of the mitochondrial genes COI (Cytochrome c Oxidase subunit I and 16S rRNA. Three species of Oxidus are clearly separated from each other; O. gigas and O. gracilis form a monophyletic sister group with O. riukiaria.

    Full Text Available This paper develops a sensorless vector controlled method for AC induction motor using sliding-mode observer. For developing the control algorithm, modeling of AC induction motor is presented. After that, a sliding mode observer is proposed to estimate the motor speed, the rotor flux, the angular position of the rotor flux and the motor torque from monitored stator voltages and currents. The use of the nonlinear sliding mode observer provides very good performance for both low and high speed motor operation. Furthermore, the proposed system is robust in motor losses and load variations. The convergence of the proposed observer is obtained using the Lyapunov theory. Hardware and software for simulation and experiment of the AC induction motor drive are introduced. The hardware consists of a 1.5kw AC induction motor connected in series with a torque sensor and a powder brake. A controller is developed based on DSP TMS320F28355. The simulation and experimental results illustrate that fast torque and speed response with small torque ripples can be achieved. The proposed control scheme is suitable to the application fields that require high performance of torque response such as electric vehicles. doi:http://dx.doi.org/10.12777/ijse.4.2.2013.39-43 [How to cite this article: Doan, P.

    Since the earliest days of the HIV/AIDS epidemic, talking about the virus has been a key way affected communities have challenged the fear and discrimination directed against them and pressed for urgent medical and political attention. Today, HIV/AIDS is one of the most prolifically and intimately documented of all health conditions, with entrenched infrastructures, practices and technologies--what Vinh-Kim Nguyen has dubbed 'confessional technologies'--aimed at encouraging those affected to share their experiences. Among these technologies, we argue, is the semi-structured interview: the principal methodology used in qualitative social science research focused on patient experiences. Taking the performative nature of the research interview as a talking technology seriously has epistemological implications not merely for how we interpret interview data, but also for how we understand the role of research interviews in the enactment of 'life with HIV'. This paper focuses on one crucial aspect of this enactment: the contemporary 'normalisation' of HIV as 'just another' chronic condition--a process taking place at the level of individual subjectivities, social identities, clinical practices and global health policy, and of which social science research is a vital part. Through an analysis of 76 interviews conducted in London (2009-10), we examine tensions in the experiential narratives of individuals living with HIV in which life with the virus is framed as 'normal', yet where this 'normality' is beset with contradictions and ambiguities. Rather than viewing these as a reflection of resistances to or failures of the enactment of HIV as 'normal', we argue that, insofar as these contradictions are generated by the research interview as a distinct 'talking technology', they emerge as crucial to the normative (re)production of what counts as 'living with HIV' (in the UK) and are an inherent part of the broader performative 'normalisation' of the virus.

    This 3-year project was a collaboration between University of California Irvine (UC Irvine), Pacific Northwest National Laboratory (PNNL), Idaho National Laboratory (INL), Argonne National Laboratory (ANL) and with an international collaborator at ForschungZentrum Jülich (FZJ). The project was led from UC Irvine under the direction of Profs. Mikael Nilsson and Hung Nguyen. The leads at PNNL, INL, ANL and FZJ were Dr. Liem Dang, Dr. Peter Zalupski, Dr. Nathaniel Hoyt and Dr. Giuseppe Modolo, respectively. Involved in this project at UC Irvine were three full time PhD graduate students, Tro Babikian, Ted Yoo, and Quynh Vo, and one MS student, Alba Font Bosch. The overall objective of this project was to study how the kinetics and thermodynamics of metal ion extraction can be described by molecular dynamic (MD) simulations and how the simulations can be validated by experimental data. Furthermore, the project includes the applied separation by testing the extraction systems in a single stage annular centrifugal contactor and coupling the experimental data with computational fluid dynamic (CFD) simulations. Specific objectives of the proposed research were: 1. Study and establish a rigorous connection between MD simulations based on polarizable force fields and extraction thermodynamic and kinetic data. 2. Compare and validate CFD simulations of extraction processes for An/Ln separation using different sizes (and types) of annular centrifugal contactors. 3. Provide a theoretical/simulation and experimental base for scale-up of batch-wise extraction to continuous contactors. We approached objective 1 and 2 in parallel. For objective 1 we started by studying a well established extraction system with a relatively simple extraction mechanism, namely tributyl phosphate. What we found was that well optimized simulations can inform experiments and new information on TBP behavior was presented in this project, as well be discussed below. The second objective proved a larger

    We examined changes in the abundance of immature Aedes aegypti at the household and water storage container level during the dry-season (June-July, 2008) in Tri Nguyen village, central Vietnam. We conducted quantitative immature mosquito surveys of 171 containers in the same 41 households, with replacement of samples, every two days during a 29-day period. We developed multi-level mixed effects regression models to investigate container and household variability in pupal abundance. The percentage of houses that were positive for I/II instars, III/IV instars and pupae during any one survey ranged from 19.5–43.9%, 48.8–75.6% and 17.1–53.7%, respectively. The mean numbers of Ae. aegypti pupae per house ranged between 1.9–12.6 over the study period. Estimates of absolute pupal abundance were highly variable over the 29-day period despite relatively stable weather conditions. Most variability in pupal abundance occurred at the container rather than the household level. A key determinant of Ae. aegypti production was the frequent filling of the containers with water, which caused asynchronous hatching of Ae. aegypti eggs and development of cohorts of immatures. We calculated the probability of the water volume of a large container (>500L) increasing or decreasing by ≥20% to be 0.05 and 0.07 per day, respectively, and for small containers (<500L) to be 0.11 and 0.13 per day, respectively. These human water-management behaviors are important determinants of Ae. aegypti production during the dry season. This has implications for choosing a suitable Wolbachia strain for release as it appears that prolonged egg desiccation does not occur in this village. PMID:22911683

    Adequate nutrient intakes among women of reproductive age (WRA) are important determinants of maternal, neonatal and child health outcomes. However, data on dietary intake for WRA in Vietnam are lacking. This paper aimed to examine the adequacy and determinants of energy and macronutrient intakes among WRA enrolled in a study of preconceptual micronutrient supplementation (PRECONCEPT) being conducted in 20 rural communes in Thai Nguyen province, Vietnam. Dietary intakes were determined for 4983 WRA who participated in the baseline survey using a previously validated 107-item (semi-quantitative) food-frequency questionnaire that was administered by trained field workers. Multivariate linear and logistic regression analyses were used to examine factors associated with energy and macronutrient intakes. A disproportionate number of energy came from starches, primarily rice. Carbohydrate, fat and protein constituted 65.6%, 19.5% and 14.8% of total energy, respectively. Fat intake was below recommended levels in 56.5% of respondents, but carbohydrate intakes were above recommended level in 54.6%. Only 0.1% and 5.2% of WRA achieved adequate intake of n-3 and n-6 long-chain polyunsaturated fatty acids, respectively. Multivariate linear regression revealed that low education, low socioeconomic status, and food insecurity were significant predictors of reduced total energy intake, reduced energy from protein and fat, and greater energy from carbohydrates. Logistic regression confirmed that inadequate macronutrient intake was more common among the poor, food insecure, and less educated. Imbalanced dietary intakes among underprivileged women reflect lack of dietary diversity. Nutrition programs should be linked with social development, poverty reduction, education programs and behavior change counseling in order to improve the nutritional status of WRA in Vietnam.

    Effects of adding four functional ingredients: inulin, pectin, galacto-oligosaccharides (GOS), and beta glucan on physical, rheology, tribology, and sensory characteristics of skim (0.1% fat) stirred yoghurt were studied. Three levels of each ingredient were chosen: inulin (7, 8, and 9%), pectin (0.2, 0.25, and 0.3%), GOS (9.1, 11.3, and 13.6%), and beta glucan (0.1, 0.2, and 0.3%). Among the investigated ingredients, inulin and GOS appeared to be preferable choices due to their ability to both reduce syneresis and slightly increase sample lubrication while maintaining texture, rheology, and sensory characteristics of skim yoghurt. Pectin and beta glucan, conversely, increased viscosity and gel strength, slightly increased sample lubrication for the skim yoghurt but created large particles (i.e., greater than 100 μm) in the product body. This led to the increase in lumpiness and residual coating while reducing smoothness and creaminess of the sample. The observed tribology behaviors of the stirred yoghurts were similar to the previous study of pot-set yoghurt whose friction curves comprised four friction zones (Nguyen, Kravchuk, Bhandari, and Prakash). The sensory characteristics of six selected samples for various texture and mouthfeel attributes obtained from a trained panel were in agreement with particle size, rheology, and tribology characteristics of the yoghurt samples. With the increasing demand for low fat and functional food, there is a need to understand the impact of adding functional ingredients in low fat yoghurt to satisfy consumers' requirements. This study investigates the effects of these functional ingredients at different dosages on physical, rheology, tribology, and sensory characteristics of skim (0.1% fat) stirred yoghurt. The results from this study may guide use of functional ingredients in yoghurt production. © 2017 Wiley Periodicals, Inc.

    Objectives  To describe the orbitopterional approach for the resection of a suprasellar craniopharyngioma with emphasis on the microsurgical and pathological anatomy of such lesions. Design  After completing the orbitopterional craniotomy in one piece including a supraorbital ridge osteotomy, the Sylvian fissure was split in a distal to proximal direction. The ipsilateral optic nerve and internal carotid artery were identified. Establishing a corridor to the tumor through both the opticocarotid and optic cisterns allowed for a wide angle of attack. Using both corridors, a microsurgical gross total resection was achieved. A radical resection required transection of the stalk at the level of the hypothalamus. Photographs of the region are borrowed from Dr Rhoton's laboratory to illustrate the microsurgical anatomy. Understanding the cisternal and topographic relationships of the optic nerve, optic chiasm, and internal carotid artery is critical to achieving gross total resection while preserving normal anatomy. Participants  The surgery was performed by the senior author assisted by Dr. Jaafar Basma. The video was edited by Dr. Vincent Nguyen. Outcome Measures  Outcome was assessed with extent of resection and postoperative visual function. Results  A gross total resection of the tumor was achieved. The patient had resolution of her bitemporal hemianopsia. She had diabetes insipidus with normal anterior pituitary function. Conclusions  Understanding the microsurgical anatomy of the suprasellar region and the pathological anatomy of craniopharyngiomas is necessary to achieve a good resection of these tumors. The orbitopterional approach provides the appropriate access for such endeavor. The link to the video can be found at: https://youtu.be/Be6dtYIGqfs .

    Full Text Available Learning styles have been a particular focus of a number of researchers over the past decades. Findings from various studies researching into how students learn highlight significant relationships between learners’ styles of learning and their language learning processes and achievement. This research focuses on a comparative analysis of the preferences of English learning styles and teaching techniques perceived by students from Thailand and Vietnam, and the teaching styles and techniques practiced by their instructors. The purposes were 1 to investigate the learning styles and teaching techniques students from both countries preferred, 2 to investigate the compatibility of the teaching styles and techniques practiced by instructors and those preferred by the students, 3 to specify the learning styles and teaching techniques students with high level of English proficiency preferred, and 4 to investigate the similarities of Thai and Vietnamese students’ preferences for learning styles and teaching techniques. The sample consisted of two main groups: 1 undergraduate students from King Mongkut’s University of Technology North Bangkok (KMUTNB, Thailand and Thai Nguyen University (TNU, Vietnam and 2 English instructors from both institutions. The instruments employed comprised the Students’ Preferred English Learning Style and Teaching Technique Questionnaire and the Teachers’ Practiced English Teaching Style and Technique Questionnaire. The collected data were analyzed using arithmetic means and standard deviation. The findings can contribute to the curriculum development and assist teachers to teach outside their comfort level to match the students’ preferred learning styles. In addition, the findings could better promote the courses provided for students. By understanding the learning style make-up of the students enrolled in the courses, faculty can adjust their modes of content delivery to match student preferences and maximize

    Injecting drug use is a primary driver of HIV epidemics in many countries. People who inject drugs (PWID) and are HIV infected are often doubly stigmatized and many encounter difficulties reducing risk behaviors. Prevention interventions for HIV-infected PWID that provide enhanced support at the individual, family, and community level to facilitate risk-reduction are needed. 455 HIV-infected PWID and 355 of their HIV negative injecting network members living in 32 sub-districts in Thai Nguyen Province were enrolled. We conducted a two-stage randomization: First, sub-districts were randomized to either a community video screening and house-to-house visits or standard of care educational pamphlets. Second, within each sub-district, participants were randomized to receive either enhanced individual level post-test counseling and group support sessions or standard of care HIV testing and counseling. This resulted in four arms: 1) standard of care; 2) community level intervention; 3) individual level intervention; and 4) community plus individual intervention. Follow-up was conducted at 6, 12, 18, and 24 months. Primary outcomes were self-reported HIV injecting and sexual risk behaviors. Secondary outcomes included HIV incidence among HIV negative network members. Fewer participants reported sharing injecting equipment and unprotected sex from baseline to 24 months in all arms (77% to 4% and 24% to 5% respectively). There were no significant differences at the 24-month visit among the 4 arms (Wald = 3.40 (3 df); p = 0.33; Wald = 6.73 (3 df); p = 0.08). There were a total of 4 HIV seroconversions over 24 months with no significant difference between intervention and control arms. Understanding the mechanisms through which all arms, particularly the control arm, demonstrated both low risk behaviors and low HIV incidence has important implications for policy and prevention programming.

    Although the dopamine D1-D2 receptor heteromer has emerging physiological relevance and a postulated role in different neuropsychiatric disorders, such as drug addiction, depression, and schizophrenia, there is a need for pharmacological tools that selectively target such receptor complexes in order to analyze their biological and pathophysiological functions. Since no selective antagonists for the D1-D2 heteromer are available, serial deletions and point mutations were used to precisely identify the amino acids involved in an interaction interface between the receptors, residing within the carboxyl tail of the D1 receptor that interacted with the D2 receptor to form the D1-D2 receptor heteromer. It was determined that D1 receptor carboxyl tail residues 404Glu and 405Glu were critical in mediating the interaction with the D2 receptor. Isolated mutation of these residues in the D1 receptor resulted in the loss of agonist activation of the calcium signaling pathway mediated through the D1-D2 receptor heteromer. The physical interaction between the D1 and D2 receptor could be disrupted, as shown by coimmunoprecipitation and BRET analysis, by a small peptide generated from the D1 receptor sequence that contained these amino acids, leading to a switch in G-protein affinities and loss of calcium signaling, resulting in the inhibition of D1-D2 heteromer function. The use of the D1-D2 heteromer-disrupting peptide in vivo revealed a pathophysiological role for the D1-D2 heteromer in the modulation of behavioral despair. This peptide may represent a novel pharmacological tool with potential therapeutic benefits in depression treatment.—Hasbi, A., Perreault, M. L., Shen, M. Y.

    This study aimed to: (1) examine the role of multiple measures of prepregnancy nutritional status (weight, height, body composition) on birth outcomes (low birth weight (LBW), small for gestational age (SGA), preterm, birth weight, birth length, infant head circumference and mid-upper arm circumference (MUAC)); (2) assess relative influence of maternal nutritional status before and during (gestational weight gain) pregnancy on birth outcomes. We used prospective data on maternal body size and composition collected from women who participated in a randomized controlled trial evaluating the impact of preconceptional micronutrient supplements (PRECONCEPT) on birth outcomes in Thai Nguyen province, Vietnam (n=1436). Anthropometric measurements were obtained before conception through delivery by trained health workers. The relationship between prepregnancy nutritional status indicators, gestational weight gain (GWG) and birth outcomes were examined using generalized linear models, adjusting for potential confounding factors. Maternal prepregnancy weight (PPW) was the strongest anthropometric indicator predicting infant birth size. A 1 standard deviation (SD) increase in PPW (5.4kg) was associated with a 283g (95%CI: 279-286) increase in birthweight. A similar and independent association was observed with birthweight for an increase of 1 SD in gestational weight gain (4kg) (250g; 95% CI: 245-255). Women with a PPW pregnancy were more likely to give birth to a SGA (OR 2.9: 95%CI 1.9-4.5, OR 3.3: 95%CI 2.2-5.1) or LBW infant (OR 3.1: 95%CI 1.5-6.2, OR 3.4: 95%CI 1.6-7.2), respectively. These findings indicate that clinical care and programs aimed at improving birth outcomes will have the greatest impact if they address maternal nutrition both before and during pregnancy. Women with a PPW pregnancy along with routine obstetric care on gestational weight gain is critical to improve birth outcomes. NCT01665378 (https://clinicaltrials.gov/show/NCT01665378).

    It is common for men to develop erectile dysfunction after radical prostatectomy. The anatomy of the rat allows the cavernous nerve (CN) to be identified, dissected, and injured in a controlled fashion. Therefore, bilateral CN injury (BCNI) in the rat model is routinely used to study post-prostatectomy erectile dysfunction. To compare and contrast the available literature on pharmacologic intervention after BCNI in the rat. A literature search was performed on PubMed for cavernous nerve and injury and erectile dysfunction and rat. Only articles with BCNI and pharmacologic intervention that could be grouped into categories of immune modulation, growth factor therapy, receptor kinase inhibition, phosphodiesterase type 5 inhibition, and anti-inflammatory and antifibrotic interventions were included. To assess outcomes of pharmaceutical intervention on erectile function recovery after BCNI in the rat model. The ratio of maximum intracavernous pressure to mean arterial pressure was the main outcome measure chosen for this analysis. All interventions improved erectile function recovery after BCNI based on the ratio of maximum intracavernous pressure to mean arterial pressure results. Additional end-point analysis examined the corpus cavernosa and/or the major pelvic ganglion and CN. There was extreme heterogeneity within the literature, making accurate comparisons between crush injury and therapeutic interventions difficult. BCNI in the rat is the accepted animal model used to study nerve-sparing post-prostatectomy erectile dysfunction. However, an important limitation is extreme variability. Efforts should be made to decrease this variability and increase the translational utility toward clinical trials in humans. Haney NM, Nguyen HMT, Honda M, et al.

    Gene sequences are routinely used to determine the topologies of unrooted phylogenetic trees, but many of the most important questions in evolution require knowing both the topologies and the roots of trees. However, general algorithms for calculating rooted trees from gene and genomic sequences in the absence of gene paralogs are few. Using the principles of evolutionary parsimony (EP) (Lake JA. 1987a. A rate-independent technique for analysis of nucleic acid sequences: evolutionary parsimony. Mol Biol Evol. 4:167-181) and its extensions (Cavender, J. 1989. Mechanized derivation of linear invariants. Mol Biol Evol. 6:301-316; Nguyen T, Speed TP. 1992. A derivation of all linear invariants for a nonbalanced transversion model. J Mol Evol. 35:60-76), we explicitly enumerate all linear invariants that solely contain rooting information and derive algorithms for rooting gene trees directly from gene and genomic sequences. These new EP linear rooting invariants allow one to determine rooted trees, even in the complete absence of outgroups and gene paralogs. EP rooting invariants are explicitly derived for three taxon trees, and rules for their extension to four or more taxa are provided. The method is demonstrated using 18S ribosomal DNA to illustrate how the new animal phylogeny (Aguinaldo AMA et al. 1997. Evidence for a clade of nematodes, arthropods, and other moulting animals. Nature 387:489-493; Lake JA. 1990. Origin of the metazoa. Proc Natl Acad Sci USA 87:763-766) may be rooted directly from sequences, even when they are short and paralogs are unavailable. These results are consistent with the current root (Philippe H et al. 2011. Acoelomorph flatworms are deuterostomes related to Xenoturbella. Nature 470:255-260).

    The enamel protein amelogenin binds to GlcNAc (Ravindranath, R. M. H., Moradian-Oldak, R., and Fincham, A.G. (1999) J. Biol. Chem. 274, 2464-2471) and to the GlcNAc-mimicking peptide (GMp) (Ravindranath, R. M. H., Tam, W., Nguyen, P., and Fincham, A. G. (2000) J. Biol. Chem. 275, 39654-39661). The GMp motif in the N-terminal region of the cytokeratin 14 of ameloblasts binds to trityrosyl motif peptide (ATMP) of amelogenin (Ravindranath, R. M. H., Tam, W., Bringas, P., Santos, V., and Fincham, A. G. (2001) J. Biol. Chem. 276, 36586 - 36597). K14 (Type I) pairs with K5 (Type II) in basal epithelial cells; GlcNAc-acylated K5 is identified in ameloblasts. Dosimetric analysis showed the binding affinity of amelogenin to K5 and to GlcNAc-acylated-positive control, ovalbumin. The specific binding of [3H]ATMP with K5 or ovalbumin was confirmed by Scatchard analysis. [3H]ATMP failed to bind to K5 after removal of GlcNAc. Blocking K5 with ATMP abrogates the K5-amelogenin interaction. K5 failed to bind to ATMP when the third proline was substituted with threonine, as in some cases of human X-linked amelogenesis imperfecta or when tyrosyl residues were substituted with phenylalanine. Confocal laser scan microscopic observations on ameloblasts during postnatal (PN) growth of the teeth showed that the K5-amelogenin complex migrated from the cytoplasm to the periphery (on PN day 1) and accumulated at the apical region on day 3. Secretion of amelogenin commences from day 1. K5, similar to K14, may play a role of chaperone during secretion of amelogenin. Upon secretion of amelogenin, K5 pairs with K14. Pairing of K5 and K14 commences on day 3 and ends on day 9. The pairing of K5 and K14 marks the end of secretion of amelogenin.

    The enamel protein amelogenin binds to the GlcNAc-mimicking peptide (GMp) (Ravindranath, R. M. H., Tam, W., Nguyen, P., and Fincham, A. G. (2000) J. Biol. Chem. 275, 39654-39661). The GMp motif is found in the N-terminal region of CK14, a differentiation marker for ameloblasts. The binding affinity of CK14 and amelogenin was confirmed by dosimetric binding of CK14 to recombinant amelogenin (rM179), and to the tyrosine-rich amelogenin polypeptide. The specific binding site for CK14 was identified in the amelogenin trityrosyl motif peptide (ATMP) of tyrosine-rich amelogenin polypeptide and specific interaction between CK14 and [(3)H]ATMP was confirmed by Scatchard analysis. Blocking rM179 with GlcNAc, GMp, or CK14 with ATMP abrogates the CK14-amelogenin interaction. CK14 failed to bind to ATMP when the third proline was substituted with threonine, as in some cases of human X-linked amelogenesis imperfecta or when tyrosyl residues were substituted with phenylalanine. Morphometry of developing teeth distinguished three phases of enamel formation; growth initiation phase (days 0-1), prolific growth phase (days 1-7), and growth cessation phase (post-day 7). Confocal microscopy revealed co-assembly of CK14/amelogenin in the perinuclear region of ameloblasts on day 0, migration of the co-assembled CK14/amelogenin to the apical region of the ameloblasts from day 1, reaching a peak on days 3-5, and a collapse of the co-assembly. Autoradiography with [(3)H]ATMP and [(3)H]GMp corroborated the dissociation of the co-assembly at the ameloblast Tomes' process. It is proposed that CK14 play a chaperon role for nascent amelogenin polypeptide during amelogenesis.

    Full Text Available Van Hong Nguyen, Beom-Jin Lee Department of Pharmacy, Bioavailability Control Laboratory, College of Pharmacy, Ajou University, Suwon, Republic of Korea Abstract: After administration of nanoparticle (NP into biological fluids, an NP–protein complex is formed, which represents the “true identity” of NP in our body. Hence, protein–NP interaction should be carefully investigated to predict and control the fate of NPs or drug-loaded NPs, including systemic circulation, biodistribution, and bioavailability. In this review, we mainly focus on the formation of protein corona and its potential applications in pharmaceutical sciences such as prediction modeling based on NP-adsorbed proteins, usage of active proteins for modifying NP to achieve toxicity reduction, circulation time enhancement, and targeting effect. Validated correlative models for NP biological responses mainly based on protein corona fingerprints of NPs are more highly accurate than the models solely set up from NP properties. Based on these models, effectiveness as well as the toxicity of NPs can be predicted without in vivo tests, while novel cell receptors could be identified from prominent proteins which play important key roles in the models. The ungoverned protein adsorption onto NPs may have generally negative effects such as rapid clearance from the bloodstream, hindrance of targeting capacity, and induction of toxicity. In contrast, controlling protein adsorption by modifying NPs with diverse functional proteins or tailoring appropriate NPs which favor selective endogenous peptides and proteins will bring promising therapeutic benefits in drug delivery and targeted cancer treatment.

    Alcohol use, a highly normative behavior in Vietnam that is associated with high rates of HIV infection and lower antiretroviral treatment (ART) adherence, has been largely overlooked by HIV prevention efforts. Using the risk environment framework, this qualitative study aims to explore the perceived microenvironmental (community-level) and endogenous (individual-level) barriers and facilitators to alcohol reduction among people living with HIV (PLHIV) with alcohol use disorders (AUDs) in Vietnam. From June-July 2014, semi-structured interviews were conducted with thirty PLHIV (18 men; 12 women) recruited from an outpatient ART clinic in Thai Nguyen province, Vietnam. All participants had scores of ≥8 on the Alcohol Use Disorders Identification Test and ten of the 30 participants were currently using injection drugs. Interviews were transcribed, translated, and analyzed to identify perceived barriers and facilitators to alcohol reduction. Most participants reported a spike in alcohol consumption at the time of HIV diagnosis. Most perceived barriers existed at the microenvironmental level, including perceived inability to refuse alcohol in the context of community-level social norms and lack of alcohol treatment programs. Two commonly mentioned endogenous barriers were compensatory behaviors when reducing injection drug use and using alcohol as a coping strategy for HIV-related sadness. Those who were able to successfully reduce alcohol use and adhere to ART reported having social support to buffer community-level social pressure and cope with sadness. It may be effective to introduce targeted alcohol reduction interventions in health care centers to address individual risk practices and microenvironmental social norms.

    Full Text Available Duy NguyenSilver School of Social Work, New York University, New York, NY, USAObjective: The use of physicians is more common than of behavioral specialists, especially in underserved Asian American communities. Despite a rapidly aging Asian American population, research has overlooked older people. This study examines the way mental health need affects the number of physician contacts by older Asian Americans.Method: This study uses data on self-identified Asian Americans aged over age 50 years derived from the 2001 California Health Interview Survey. A total of 1191 Asian Americans from Chinese, Filipino, Korean, and Vietnamese backgrounds were studied. Replicate weights were applied to account for the survey’s complex sampling methods. Linear regression was used to identify the number of physician contacts.Results: Overall, respondents had seen a doctor an average of five times in the previous 12 months; 7% perceived that they had a mental health need. Perceiving a mental health need was associated with a decreased number of physician contacts for Filipino and Korean Americans.Conclusion: This study revealed interethnic differences among older Asian Americans’ contact with physicians. As older Filipino and Korean Americans who perceive a mental health need have fewer contacts with their physician, correctly identifying mental health needs in the health care system for these groups is crucial. Health and mental health professionals can work toward reducing mental health disparities by accounting for older Asian Americans’ help-seeking patterns when designing evidence-based interventions.Keywords: minority groups, Asians, health service use

The development of tumor-targeting systems may improve treatment outcomes. Nanomedicine platforms are of particular interest for enhancing chemotherapeutic efficiency, and they include polymeric micelles, which enable targeting of multiple drugs to solid tumors, including imaging and therapeutic agents. This allows concurrent diagnosis, targeting strategy validation, and efficacy assessment. We used polymeric micelles containing the T1-weighted magnetic resonance imaging contrast agent gadolinium-diethylenetriaminpentaacetic acid (Gd-DTPA and the parent complex of the anticancer drug oxaliplatin [(1,2-diaminocyclohexaneplatinum(II (DACHPt] for simultaneous imaging and therapy in an orthotopic rat model of HCC. The Gd-DTPA/DACHPt-loaded micelles were injected into the hepatic artery, and magnetic resonance imaging performance and antitumor activity against HCC, as well as adverse drug reactions were assessed. After a single administration, the micelles achieved strong and specific tumor contrast enhancement, induced high levels of tumor apoptosis, and significantly suppressed tumor size and growth. Moreover, the micelles did not induce severe adverse reactions and significantly improved survival outcomes in comparison to oxaliplatin or

    the CME articles as intelligible to a wider medical audience and filling clinically relevant knowledge gaps; 78.57% (1,838,358/2,339,781) of the sample gave the CME articles very good or good marks. Cluster analysis revealed three groups, one comprised of only women, with two-thirds working in private practice. The CME article series of Deutsches Ärzteblatt is used on a regular basis by a considerable proportion of all physicians in Germany; its multidisciplinary articles are suitable to a broad spectrum of medical specialties. The program seems to be particularly attractive for physicians in private practice and those who want to participate from their homes and on weekends. Although many physicians emphasize that the articles address gaps in knowledge, it remains to be investigated how this impacts professional performance and patient outcomes. ©Hildegard Christ, Jeremy Franklin, Reinhard Griebenow, Christopher Baethge.

The aims of the present study were to confirm these data in an unselected patient population in daily practice and to determine the impact of physical activity on blood pressure control. Methods: In a multicenter, noninterventional study, 3,333 patients with either insufficient blood pressure control on olmesartan 40 mg alone or on a fixed/free combination of olmesartan 40 mg and HCTZ 12.5/25 mg were primarily assessed for safety and tolerability of the fixed-dose combination of olmesartan 40 mg and HCTZ 12.5/25 mg at 24 ± 2 weeks. Secondary objectives were blood pressure reduction, treatment compliance, and impact of physical activity as measured by the sum of weekly energy costs. Results: The mean patient age was 63.2 ± 11.46 years, mean baseline blood pressure was 159.6 ± 15.28/93.5 ± 9.52 mmHg, and 70.9% had at least one additional cardiovascular risk factor. Adverse drug reactions were rare (n = 19, and no serious adverse drug reactions occurred. Compliance with drug therapy was at least sufficient in more than 99% of patients at the end of the study. Blood pressure at the last available visit was reduced by 26.1 ± 15.5/13.0 ± 10.1 mmHg versus baseline (P < 0.0001, but had reduced effectiveness in patients ≥75 years with diabetes or impaired renal function.

    This PhD thesis represents work done between Aug. 2003 and Dec. 2006 in Reinhard F. Werner's quantum information theory group at Technische Universitaet Braunschweig, and Artur Ekert's Centre for Quantum Computation at the University of Cambridge. My thesis falls into the field of abstract quantum information theory. This work investigates both fundamental properties of quantum channels and their asymptotic capacities for classical as well as quantum information transfer. Stinespring's theorem is the basic structure theorem for quantum channels. It implies that every quantum channel can be represented as a unitary evolution on an enlarged system. In Ch. 3 we present a continuity theorem for Stinespring's representation: two quantum channels are similar if and only if it is possible to find unitary implementations that are likewise similar, with dimension-independent norm bounds. The continuity theorem allows to derive a formulation of the information-disturbance tradeoff in terms of quantum channels, and a continuity estimate for the no-broadcasting principle. In Ch. 4 we then apply the continuity theorem to give a strengthened no-go proof for quantum bit commitment, an important cryptographic primitive. This result also provides a natural characterization of those protocols that fall outside the standard setting of unconditional security, and thus may allow secure bit commitment. We present a new such protocol whose security relies on decoherence in the receiver's lab. Ch. 5 reviews the capacities of quantum channels for the transfer of both classical and quantum information, and investigates several variations in the notion of channel capacity. Memory effects are then investigated in detail in Ch. 6. We advertise a model which is sufficiently general to encompass all causal automata: every quantum process in which the outputs up to any given time t do not depend on the inputs at times t'>t can be represented as a concatenated memory channel.

This study aims to provide accurate and timely information about the economic impacts of type 2 diabetes mellitus (T2DM in Vietnam. Method: The cost-of-illness estimates followed a prospective, prevalence-based approach from the societal perspective of T2DM with 392 selected diabetic patients who received treatment from a public hospital in Ho Chi Minh City, Vietnam, during the 2016 fiscal year. Results: In this study, the annual cost per patient estimate was US $246.10 (95% CI 228.3, 267.2 for 392 patients, which accounted for about 12% (95% CI 11, 13 of the gross domestic product per capita in 2017. That includes US $127.30, US $34.40 and US $84.40 for direct medical costs, direct nonmedical expenditures, and indirect costs, respectively. The cost of pharmaceuticals accounted for the bulk of total expenditures in our study (27.5% of total costs and 53.2% of direct medical costs. A bootstrap analysis showed that female patients had a higher cost of treatment than men at US $48.90 (95% CI 3.1, 95.0; those who received insulin and oral antidiabetics (OAD also had a statistically significant higher cost of treatment compared to those receiving OAD, US $445.90 (95% CI 181.2, 690.6. The Gradient Boosting Regression (Ensemble method and Lasso Regression (Generalized Linear Models were determined to be the best models to predict the cost of T2DM (R2=65.3, mean square error [MSE]=0.94; and R2=64.75, MSE=0.96, respectively.

    A randomized controlled trial was conducted in 2015 to evaluate a mobile continuing medical education (mCME) intervention that provided daily text messages to community-based physicians' assistants (CBPAs) in Thai Nguyen Province, Vietnam. Although the intervention failed to improve medical knowledge over a 6-month period, a companion qualitative study provided insights on the views and experiences of intervention participants. We conducted focus group discussions (FGDs) and in-depth interviews (IDIs) among participants randomized to receive text messages containing either simple medical facts or quiz questions. Trained interviewers collected data immediately following the conclusion of the trial in December 2015. Using semi-structured question guides, respondents were queried on their views of the intervention, positive and negative, and perceived impacts of the intervention. During analysis, after learning that the intervention had failed to increase knowledge among participants, we also examined reasons for lack of improvement in medical knowledge. All analyses were performed in NVivo using a thematic approach. A total of 70 CBPAs engaged in one of 8 FGDs or an IDI. One-half were men; average age among all respondents was 40 years. Most (81%) practiced in rural settings and most (51%) focused on general medicine. The mean length of work experience was 3 years. All respondents made positive comments about the intervention; convenience, relevance, and quick feedback (quiz format) were praised. Downsides encompassed lack of depth of information, weak interaction, technology challenges, and challenging/irrelevant messages. Respondents described perceived impacts encompassing increased motivation, knowledge, collegial discussions, Internet use to search for more information, and clinical skills. Overall, they expressed a desire for the intervention to continue and recommended expansion to other medical professionals. Overreliance on the text messages, lack of

Total asthma-related disability days, including in-bed days and activity-restricted days, were estimated by multiplying the difference in the means of total disability days between asthmatics and nonasthmatics adjusted for sociodemographic characteristics and other health conditions by a multiple linear regression, with the number of asthmatics in the population. Number of productivity loss days was a sum between the number of in-bed days (absenteeism and the number of activity-restricted days multiplied by a reduction in functional level (presenteeism, adjusted for five working days per week. Other data from Alberta or Canadian published literature, such as a reduction in functional level of 20%–30%, a labor participation rate of 73%, and an average wage of $158 per day in 2005, were also used for analyses.Results: The prevalence of asthma was estimated at 8.5% among approximately 2.1 million people of working age in Alberta in 2005. The difference in the means of total disability days between asthmatics and nonasthmatics was 0.487 (95% CI: 0.286–0.688 in a period of two weeks or 12.7 (7.5–17.9 in one year. With the reduction in functional level of 20%–30%, the number of asthma-related productivity loss days was estimated from 442 (259–624 to 533 (313–753 thousand, respectively. The corresponding cost was from $70 ($41–$99 to $84 ($49–$119 million.

Se revisaron las encuestas epidemiológicas realizadas a todas las embarazadas con serologías positivas por el Departamento de Enfermedades de Transmisión Sexual y de cada una de ellas se extrajeron las variables necesarias para estudiar las gestantes que finalmente se diagnosticaron con sífilis. Como resultado de nuestro trabajo encontramos una incidencia de sífilis durante el embarazo de 28,66 x 1 000 gestantes. Existe un elevado porcentaje de gestantes con sífilis en edades comprendidas entre 15 y 19 años, la mayoría pertenecían a la raza negra. Llama la atención la gran proporción de mujeres casadas y con bajo nivel cultural. En cuanto a la categoría ocupacional, predominó el ama de casa y un gran número de casos se diagnosticó en el primer trimestre. Del total de casos, sólo 4 presentaron manifestaciones dermatológicas y 34 recibieron el tratamiento de elección. No se reportó ningún caso de sífilis congénita.A descriptive and retrospective study was conducted at the Department of Sexually Transmitted Diseases of the "Nugyen Van Troi" Teaching Polyclinic from 1993 to 1995, aimed at reducing morbidity and mortality due to sexually transmitted diseases among pregnant women. All the epidemiological surveys applied to pregnant women with positive serology by this Departament were reviewed. All the variables necessary to study these women who finally had a syphilis diagnosis were used. As a result of our work we found an incidence of syphilis during pregnancy of 28.66 x 1 000 pregnant women. There is a high percentage of syphilis at ages between 15 and 19 years.

However, elucidating such patterns may improve our understanding of the underlying mechanisms involved in these common causes of chronic pain. We sought to describe the pattern of comorbid pain clustering in a population-based sample of women with diagnosed vulvodynia. Methods: A total of 1457 women with diagnosed vulvodynia self-reported their type of vulvar pain as localized, generalized, or both. Respondents were also surveyed about the presence of comorbid pain conditions, including temporomandibular joint and muscle disorders, interstitial cystitis, fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, endometriosis, and chronic headache. Age-adjusted latent class analysis modeled extant patterns of comorbidity by vulvar pain type, and a multigroup model was used to test for the equality of comorbidity patterns using a comparison of prevalence. A two-class model (no/single comorbidity versus multiple comorbidities had the best fit in individual and multigroup models. Results: For the no/single comorbidity class, the posterior probability prevalence of item endorsement ranged from 0.9% to 24.4%, indicating a low probability of presence. Conversely, the multiple comorbidity class showed that at least two comorbid conditions were likely to be endorsed by at least 50% of women in that class, and irritable bowel syndrome and fibromyalgia were the most common comorbidities regardless of type of vulvar pain. Prevalence of the multiple comorbidity class differed by type of vulvar pain: both

A growing body of evidence documents its diverse functions contributing to tumorigenesis and cancer progression. As such, discovery of agents that can target FoxM1 would be valuable for the treatment of CCA. The quinoline-based compounds, namely clioquinol (CQ and nitroxoline (NQ, represent a new class of anticancer drug. However, their efficacy and underlying mechanisms have not been elucidated in CCA. In this study, anticancer activities and inhibitory effects of CQ and NQ on FoxM1 signaling were explored using CCA cells.Methods: The effects of CQ and NQ on cell viability and proliferation were evaluated using the colorimetric 3-(4,5-dimethylthiazol-2yl-5-(3-carboxymethoxyphenyl-(4-sulfophenyl-2H-tetrazolium (MTS assay. Colony formation and cell migration affected by CQ and NQ were investigated using a clonogenic and a wound healing assay, respectively. To demonstrate the agents’ effects on FoxM1 signaling, expression levels of the target genes were quantitatively determined using real-time polymerase chain reaction.Results: CQ and NQ significantly inhibited cell survival of HuCCT1 and Huh28 in a dose- and a time-dependent fashion. Further investigations using the rapidly proliferating HuCCT1 cells revealed significant suppression of cell proliferation and colony formation induced by low doses of the compounds. Treatment of CQ and NQ repressed expression of cyclin D1 but enhanced expression of p21. Most importantly, upon CQ and NQ treatment

Materials and methods: In 2014, a postal mail questionnaire was sent to all GPs in the Lorraine region. This questionnaire was designed to identify GPs’ decision-making criteria. It was based on the results of a literature review and on existing guidelines. During 1 year, corrective measures were implemented to improve practices, especially training sessions for physicians and production of specific tools, including a guide to the accepted ideas in geriatric oncology. In 2015, the same questionnaire was resent to all GPs to compare the answers. Results: In 2014, 430 questionnaires were returned out of 2,048 sent, and in 2015, 378 questionnaires were returned out of 2,066 sent. Our results show for the first time that there exists a significant difference in the overall decision criteria between the two survey periods. This difference mainly concerns criteria related to the cancerous diseases. Physicians tend to consider the principal decision criteria to be less important after the training period. GPs express the importance of accessibility to specialists for additional advice in both 2014 and 2015; the distance between the patient’s home and an adapted care facility and the

The underlying genetic mechanisms identified for colistin (the mcr-1 gene) and quinolone (gyrA gene mutations) are likely to play a major role in AMR to those compounds. Conjugation experiments led to the identification of a 63-kb plasmid, similar to one recently identified in China, as the potential carrier of the mcr-1 gene. These results should encourage greater restrictions of such antimicrobials in Southeast Asian farming systems. Copyright © 2016 Nguyen et al.

    Erectile dysfunction (ED) is an important health concern that can significantly affect a man's psychosocial well-being. ED has traditionally been considered a disease of old age; however, contemporary evidence suggests a growing incidence of ED in men younger than 40 years. The process of achieving an erection is multifaceted; there are many potential mechanisms that can be disrupted. It is critical to identify the specific causes of ED before proceeding with potentially costly and invasive therapeutic options. Advances in diagnostic and treatment modalities offer opportunities to identify and manage young men with ED. To provide an update on the prevalence and risk factors of ED in young men and to provide a framework to guide clinicians in identifying and managing the affected young man. Comprehensive review of the literature pertaining to ED in young men. ED in young men was assessed by outlining the prevalence according to recent epidemiologic studies. The pathophysiology, diagnostic considerations, risk factors, and etiologies were reviewed. Large multinational studies have estimated the prevalence of ED in young men to be as high as 30%. Several studies have stratified the etiologies of ED into psychogenic and organic causes. Psychogenic etiologies of ED include depression, anxiety, and partner-related difficulties. These patients tend to experience sudden onset of symptoms, with decreased libido and good quality of spontaneous or self-stimulated erections. Organic etiologies include vasculogenic, endocrinologic, neurogenic, iatrogenic, and structural components. These patients usually experience gradual onset of symptoms and a low to normal libido. Conservative treatments such as phosphodiesterase type 5 inhibitors continue to be the mainstay treatment. ED in young men is an increasingly common condition. A careful diagnostic evaluation should focus on the identification of any underlying etiology to ensure appropriate management of patients. Nguyen HMT

As the world is currently concerned with the government of China and its growing power along its southern frontier, it is useful to consider past events that reflect the pattern of interactions between this northern power and the states lying along this frontier. East Asian historians Kathlene Baldanza and Bradley Camp Davis provide excellent, detailed studies of Vietnam and Beijing as they worked to resolve issues in the territory separating them. Although in the early modern age, the scholar-officials of both lands shared a Confucian ideology and practice, the asymmetric relationship between the two lands (Womack 2006 engendered very different perspectives on each side of the frontier. Baldanza and Davis offer valuable views on these relationships: the former focusing on the Ming dynasty (1368–1644 in China; the latter on the late Qing (1850–1911. Each of the authors also gives us a view of the Vietnamese dynasties of those ages: the Tran (1225–1400, the Le (1428–1527, 1592–1788, the Mac (1528–1592 of Dai Viet, and the Nguyen (1802–1945 of Vietnam.

Baldanza does a masterful job with contemporary Vietnamese and Chinese documents (both in Chinese characters, mining the interactions between the two. Davis, in a more recent setting, does a fine job bringing local oral traditions together with official imperial documents of both Hue and Beijing, as well as official and nonofficial French documentation.

    Full Text Available 1975, the Vietnam War has just ended, but the cold war and the clash of ideologies are still going on. This would of course be the perfect background for some run-of-the-mill thriller written by a white American for a Western audience. And without knowing anything further, we might first think that The Sympathizer, which was recently translated into German and marketed as a “thriller” and “spy novel”, would be just one of those. However, things and people are all too often not what they seem to be – an adage which has never been more true than in this story. Far more than simply a thriller, it is also a political novel, a satirical story, refugee literature and a critique of modern mass media, all interspersed with discursive passages and spiced with literary references and aphorisms. Furthermore, the author is not a white American. The Sympathizer is the debut novel of Vietnamese-American Viet Thanh Nguyen, which won him the Pulitzer Prize in 2016 along with a great many other awards. Nguyen was born in Vietnam and grew up in the USA from where he experienced both cultures and had insight to both perspectives on the Vietnam War. He is a Professor of English and American Studies and Ethnicity primarily focused on “Americanization”, how the American perspective continues to dominate film, literature and pop culture. His book is a critique of this prevailing view and includes the issues of acculturation and identity crisis of immigrants, along with the importance of loyalty and relationships (or the lack of those. The narrator and protagonist of the story is a man who has no name and is only referred to as “the captain” throughout the book. We encounter him fleeing Saigon, accompanying a general of the South Vietnamese army, we know already that he has a secret. In the very first lines he reveals that he is a sleeper agent and actually working for the Viet Cong and spying on the South Vietnamese military and the CIA. The captain

TAF has been shown to be a potent inhibitor of HBV replication at a low dose, with high intracellular concentration and more than 90% lower systemic TFV concentration than tenofovir disoproxil fumarate (TDF. In two randomized, double-blind, multinational, Phase 3, non-inferiority trials for hepatitis B e antigen (HBeAg-positive and -negative patients (primary analysis: 48 weeks, TAF 25 mg orally once-daily was not inferior to TDF 300 mg in achieving an HBV DNA level <29 IU/mL at week 48. No amino-acid substitutions associated with viral breakthrough were detected by deep sequencing, and no resistance to TAF was found through week 96. In addition, no difference in the frequency of HBeAg or hepatitis B surface antigen loss was observed. However, TAF was associated with a significantly higher ALT normalization rate than was TDF, based on the American Association for the Study of Liver Diseases criteria (male: ALT ≤30 U/L and female: ALT ≤19 U/L. An analysis of renal safety showed that patients treated with TAF had a significantly lower decrease in the estimated glomerular filtration rate level than did patients treated with TDF. Similarly, the declines of hip and spine bone mineral density were significantly less in the TAF group. These trends of efficacy and renal/bone safety continued through week 96. Longer term follow-up and real-world data will be required to determine if the differences in viral/biochemical response and renal/bone safety seen with TAF in comparison with TDF are clinically relevant.

Methods: Providers who issued ≥1 insulin prescription between January 1, 2011 and September 30, 2011 were selected from administrative claims contained in the HealthCore Integrated Research DatabaseSM. Adult diabetes patients with visits to these providers were identified. Providers were dichotomized into high- [HVPs] and low-volume providers [LVPs] based on median number of diabetes patients per provider. Results: We identified 15,349 HVPs and 15,313 LVPs (median number of patients = 14. Most HVPs were located in the Midwest (6,291 [41.0%] and South (5,092 [33.2%], while LVPs were evenly distributed across regions. Over 80% (12,769 of HVPs practiced family or internal medicine; 6.4% (989 were endocrinologists. HVPs prescribed insulin to an average of 25% of patients. Patients of HVPs (522,527 had similar characteristics as patients of LVPs (80,669, except for geographical dispersion, which followed that of providers. Approximately 65% of patients were aged 21-64 years and 97% had type 2 diabetes. Among patients with ≥1 available HbA1C result during 2011 (103,992, 48.3% (50,193 had an average HbA1C ≥7.0%. Among patients initiating insulin, 79.6% (22,205 had an average HbA1C ≥7.0%. Conclusion: The observed provider and patient populations support the feasibility of the prospective study. Sampling of patients from HVPs is efficient while minimizing bias as patient characteristics are similar to those from LVPs.

    Polycyclic aromatic hydrocarbons (PAHs) and their nitrated derivatives (nitro-PAHs) have been shown to be mutagenic in bacterial and mammalian assays and are classified as probable human carcinogens. Semi-volatile PAHs partition between the gas and particulate phases, depending on their liquid-phase vapor pressures and ambient temperatures. These PAHs have been extensively measured in ambient particulate matter and can ultimately undergo long-range transport from source regions (e.g., China to the western USA) (1). During transport these particle-bound PAHs may undergo reaction with NO3/N2O5 to form nitro-PAH derivatives. Previous studies of heterogeneous nitration of PAHs have used particles composed of graphite, diesel soot, and wood smoke (2-4). This study investigates the heterogeneous formation of nitro-PAHs from ambient particle-bound PAHs from Beijing, China and sites located within the Los Angeles air basin. These ambient particle samples, along with filters coated with isotopically labeled PAHs, were exposed to a mix of NO2/NO3/N2O5 in a 7000 L Teflon chamber, with analysis focused on the heterogeneous formation of molecular weight 247 and 273 nitro-PAHs. The heterogeneous formation of certain nitro-PAHs (including1-nitropyrene and 1- and 2-nitrotriphenylene) was observed for some, but not all, ambient samples. Formation of nitro-PAHs typically formed through gas-phase reactions (2-nitrofluoranthene and 2-nitropyrene) was not observed. The effect of particle age and local photochemical conditions during sampling on the degree of nitration in environmental chamber reactions, as well as ambient implications, will be presented. 1.

All participants met with a nurse to develop an individualized exercise plan, were issued a pedometer and exercise booklet, and instructed to continue to log their daily exercise and symptoms. MOBILE-Coached also received weekly reinforcement text messages on their cell phones; reports of worsening symptoms were automatically flagged for follow-up. Usability and satisfaction were assessed. Participants completed incremental cycle and six minute walk (6MW tests, wore an activity monitor for 14 days, and reported their health-related quality of life (HRQL at baseline, three, and six months.Results: The sample had a mean age of 68 ± 11 and forced expiratory volume in one second (FEV1 of 40 ± 18% predicted. Participants reported that logging their exercise and symptoms was easy and that keeping track of their exercise helped them remain active. There were no differences between groups over time in maximal workload, 6MW distance, or HRQL (p > 0.05; however, MOBILE-Self-Monitored increased total steps/day whereas MOBILE-Coached logged fewer steps over six months (p = 0.04.Conclusions: We showed that it is feasible to deliver a cell phone-based exercise persistence intervention to patients with COPD post-rehabilitation and that the addition of coaching appeared to be no better than self-monitoring. The latter finding needs to be interpreted with caution since this was a purely exploratory study.Trial registration: Clinical

    The Global Inundation Extent from Multi-Satellite (GIEMS) provides multi-year monthly variations of the global surface water extent at about 25 kmx25 km resolution, from 1993 to 2007. It is derived from multiple satellite observations. Its spatial resolution is usually compatible with climate model outputs and with global land surface model grids but is clearly not adequate for local applications that require the characterization of small individual water bodies. There is today a strong demand for high-resolution inundation extent datasets, for a large variety of applications such as water management, regional hydrological modeling, or for the analysis of mosquitos-related diseases. Even for climate applications, the GIEMS resolution might be limited given recent results on the key importance of the smallest ponds in the emission of CH4, as compared to the largest ones. If the inundation extent is combined to altimetry measurements to obtain water volume changes, and finally river discharge to the ocean (Frappart et al. 2011), then a better resolved inundation extent will also improve the accuracy of these estimates. In the context of the SWOT mission, the downscaling of GIEMS has multiple applications uses but a major one will be to use the SWOT retrievals to develop a downscaling of GIEMS. This SWOT-compatible downscaling could then be used to built a SWOT-compatible high-resolution database back in time from 1993 to the SWOT launch date. This extension of SWOT record is necessary to perform climate studies related to climate change. This paper present three approaches to do downscale GIEMS. Two basins will be considered for illustrative purpose, Amazon, Niger and Mekhong. - Aires, F., F. Papa, C. Prigent, J.-F. Cretaux and M.

The measurement of FENO is utilized to assist in the diagnosis and treatment of children with asthma, especially for those treated with inhaled corticosteroids. Objectives: The aims of this study were to evaluate the correlations between FENO and atopic status, blood eosinophil levels, FCER2 mutation, and asthma control in Vietnamese children. Subjects and methods: This was a prospective and descriptive study approved by the local Ethical Board. All children with uncontrolled asthma, seen in the National Hospital of Pediatrics (Hanoi, Vietnam, were included. Exhaled breath FENO, blood eosinophils, skin prick test, total IgE, asthma control test (ACT, and FCER2 gene polymorphism were performed at inclusion. They were followed up at 3 months to evaluate clinical status, FENO levels, and ACT. Results: Forty-two children with uncontrolled asthma with a mean age of 10±3 years (6–16 years were included. The male/female ratio was 2.5/1. The mean FENO levels were 26±25 ppb. FENO was significantly higher in patients with a positive skin prick test for respiratory allergens (P<0.05. FENO was significantly correlated with blood eosinophil levels (r=0.5217; P=0.0004. Five of the 32 subjects (15.6% had a mutation of FCER2 gene (rs28364072 SNP.

In Group 1 Per/Ind was initiated in newly diagnosed patients (n = 7032; in Group 2 Per/Ind replaced previous therapy in patients already treated but having either their BP still uncontrolled or experiencing side-effects (n = 7423; in Group 3 Per/Ind was added to previous treatment in patients with persistently high BP (n = 3483. BP was considered normalized when ≤ 140/90 mm Hg. A multivariate analysis for predictors of BP normalization was performed.Results: Subjects were on average 62 years old and had a baseline BP of 162.3/93.6 mm Hg. After treatment with Per/Ind, BP normalization was reached in 69.6% of patients in the Initiation group, 67.5% in the Replacement Group, and 67.4% in the Add-on Group (where patients were more frequently at risk, diabetic, or with target organ damage. Mean decreases in systolic BP of 22.8 mm Hg and in diastolic BP of 12.4 mm Hg were recorded. Conclusions: This trial was established to reflect everyday clinical practice, and a treatment strategy based on the Per/Ind combination, administered as initial, replacement, or add-on therapy, led to normalization rates that were superior to those observed in Europe in routine practice. These results support recent hypertension guidelines which encourage the use of combination therapy in the management of arterial hypertension.Keywords: perindopril, indapamide, blood

With international funding decreasing, determining the total cost of HIV/AIDS treatment is necessary in order to develop a master plan for the transition of ART services delivery and management. We analyzed the costs of HIV/AIDS treatment paid by both HIV programs and patients in a central outpatient clinic, and we explored factors associated with the capacity of patients to pay for this service. Methods: Patients (n=315 receiving ART in the Department of Infectious Diseases at Bach Mai Hospital, Hanoi, Vietnam, were interviewed. Patient records and expenses were reviewed. Results: The total cost of ART per patient was US$611 (75% from health care providers, 25% from patients or their families. The cost of a second-line regimen was found to be 2.7 times higher than the first-line regimen cost. Most outpatients (73.3% were able to completely pay for all of their ART expenses. Capacity to pay for ART was influenced by five factors, including marital status, distance from house to clinic, patient's monthly income, household economic condition, and health insurance status. Most of the patients (84.8% would have been willing to pay for health insurance if a copayment scheme for ART were to be introduced. Conclusion: This study provides evidence on payment capacity of HIV/AIDS patients in Vietnam and supplies information on ART costs from both provider and patient perspectives. In particular, results from this study suggest that earlier access to ART

    Voltage-gated sodium channels (Na V s) are activated by transiting the voltage sensor from the deactivated to the activated state. The crystal structures of several bacterial Na V s have captured the voltage sensor module (VSM) in an activated state, but structure of the deactivated voltage sensor remains elusive. In this study, we sought to identify peptide toxins stabilizing the deactivated VSM of bacterial Na V s. We screened fractions from several venoms and characterized a cystine knot toxin called JZTx-27 from the venom of tarantula Chilobrachys jingzhao as a high-affinity antagonist of the prokaryotic Na V s Ns V Ba (nonselective voltage-gated Bacillus alcalophilus ) and NaChBac (bacterial sodium channel from Bacillus halodurans ) (IC 50 = 112 nM and 30 nM, respectively). JZTx-27 was more efficacious at weaker depolarizing voltages and significantly slowed the activation but accelerated the deactivation of Ns V Ba, whereas the local anesthetic drug lidocaine was shown to antagonize Ns V Ba without affecting channel gating. Mutation analysis confirmed that JZTx-27 bound to S3-4 linker of Ns V Ba, with F98 being the critical residue in determining toxin affinity. All electrophysiological data and in silico analysis suggested that JZTx-27 trapped VSM of Ns V Ba in one of the deactivated states. In mammalian Na V s, JZTx-27 preferably inhibited the inactivation of Na V 1.5 by targeting the fourth transmembrane domain. To our knowledge, this is the first report of peptide antagonist for prokaryotic Na V s. More important, we proposed that JZTx-27 stabilized the Ns V Ba VSM in the deactivated state and may be used as a probe to determine the structure of the deactivated VSM of Na V s.-Tang, C., Zhou, X., Nguyen, P.

Psychosocial is defined as the interrelation of social factors with an individual's thoughts and behavior. The assessment of the psychosocial impact of skin disease on a patient can help direct the dermatologists' treatment goals. To evaluate the psychosocial impact of skin disease, we conducted a review of the literature on three skin conditions with onsets at various stages of life: acne, vitiligo, and psoriasis. Methods: A PubMed search was conducted in March 2015 using the terms “psychosocial” AND “acne”, “psychosocial” AND “vitiligo”, and “psychosocial” AND “psoriasis”. The results were limited to articles published in English in the past 5 years studying patients of all ages. Results and their references were evaluated for relevance according to their discussion of psychosocial qualities in their patients and the validity of psychosocial assessments. The search for acne yielded 51 results, and eleven were found to be relevant; vitiligo yielded 30 results with ten found to be relevant; and psoriasis yielded 70 results with seven found to be relevant. Results: According to the articles evaluated, 19.2% of adolescent patients with acne were affected in their personal and social lives. Social phobia was present in 45% of patients with acne compared to 18% of control subjects. Race and sex played a role in self-consciousness and social perceptions of the disease. Vitiligo

    dominant lighting technology due to its superior electrical to optical conversion efficiency. A unique LED structure based on CdS is presented by Ye et al [8]. A detailed study by Nguyen et al [9] provides a fundamental understanding of the non-radiative recombination mechanisms in GaN-based white light emitting nanowire diodes grown on Si substrates. Another application of III-nitrides is in photovoltaic devices (solar cells) [10]. InGaN is the only semiconductor alloy whose energy bandgap can be continuously varied across nearly the entire solar spectrum, promising a new generation of solar cells. Another potentially important application for nanowires is the efficient production of H2 from the photocatalytic splitting of water, where the H2 can be used as an energy carrier. Water splitting based on unique nanostructures include Fe2O3 [11], CuS/ZnO [12], and ZnO/Si [13]. Another candidate for photocatalysis, among other applications, is copper oxide nanowires, reviewed by Gregor et al [14].

Other methods consider the dielectric properties of the soil as smoothly variable along probe axis (Greco, 1999; Oswald et al., 2003; Greco, 2006). Aim of the study is testing the applicability to layered soils of the inverse method for the estimation of water content profiles along vertical TDR waveguides, originally applied in laboratory to homogeneous soil samples with monotonic moisture distributions (Greco, 2006), and recently extended to field measurements with more general water content profiles (Greco and Guida, 2008). Influence of soil electrical conductivity, uniqueness of solution, choices of parametrization, parameters identifiabilty, sensitivity of the method to chosen parameters variations are discussed. Finally, the results of the application of the inverse method to a series of infiltration and evaporation experiments carried out in a flume filled with three soil layers of different physical characteristics are presented.

    came so close to uncovering the law of refraction [12], once termed his professional efforts 'the restless search for and interpretation of causes, the spiritual anguish for grace' [13]. The outcry will resonate with anyone who has applied themselves in the endeavours of scientific research or indeed any other discipline as a scholar, athlete, artist or otherwise. But while there may be frustrations along the way, the achievements in the end make the effort worthwhile. The work in this issue is just one example of what the 'restless search' in scientific research can achieve in sensing technology using nanoscale systems.

  13. Designing a spatial decision-support system to improve urban resilience to floods

    Since Hurricane Katrina (2005), the scientific-political-urban attention is focusing on urban resilience to floods. To prevent the recurrence of such a deadly and costly event ( 82 billion, Serre et al, 2014), experts began to question pre- and post- disaster management. Until now, managers and urban planners have been working on flood risk, according to the paradigm of prevention. However, following Katrina, a new approach was gradually integrated and the concept of resilience applied to urban areas (Serre, 2011). The resilience concept, used in ecology and defined by Holling (1973), refers to the ability of a system to keep its own variables despite changes and analyses the capacity of an (eco)system to tolerate disturbances without changing its state. To link it with flood risk management, this concept takes more into account water and would lead to technical, architectural, social, urban and political innovation (Serre et al, 2016). However, despite 12 years after Katrina, very few concrete actions have been made (Barroca and Serre, 2013). Based on this argument, and several abortive studies, we wish to re-address the operationalization of resilience by redefining its objectives and expectations. While in Europe some studies have been done to build up vulnerability indicators (Barroca et al, 2006; Opach et al, 2016; Wiréhn et al, 2016), few still talk about resilience. When some do (Folke et al, 2010; Lhomme et al, 2011; Nguyen et al, 2013; Suarez et al, 2016), they mainly speak about technical resilience without integrating social resilience. Our objective is thus to imagine a system facilitating the understanding of this concept, its integration in management and development policies. We started on the methodology of information systems, organized system for collection, organization, storage and communication of information, and more precisely on observatories, information systems using the methodology of observation. These last years, we assist to an

    Full Text Available Introduction Nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. On the other hand, sorghum (Sorghum bicolor L. is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. All studies have showed the positive effects of Silicon on growth and yield of plants in both normal and stress conditions. The aim of this experiment was to improve salinity tolerance of Sorghum by application of Silicon. Materials and Methods A split plot experiment based on randomized complete block design with three replications in both normal and salt stress conditions was carried out at research farm of Shahid Bahonar University of Kerman in 2013. Silicon treatments (0 and 6 mM were considered as main plot and various sorghum genotypes (payam, sepideh, TN-4-70, TN-04-71, TN-04-39, TN-04-107, TN-04-100, TN-04-37, TN-04-68, TN-04-83, TN-04-62 and TN-04-95 were assigned to sub plots. The sodium silicate was used as silica source. The data were analyzed by SAS software using combine analysis. Means comparisons were accomplished by Duncan multiple range test at 5% probability level. Some of the measured traits were as follow: Relative water content (Ritchie and Nguyen, 1990, Relative permeability (33, leaf area index and chlorophyll index (by SPAD. Results and Discussion According to the results, use of silicon led to increase of RWC under salinity stress, while RWC decreased by 13% when no silicon applied. Salinity significantly decreased 1000-grain weight. Maximum grain yield obtained from TN-04-37 (987.6 g m-2 under normal condition with foliar application of silicon. Application of silicon under stress condition led to 38% increase in grain yield of Sepideh compared to control. Under salt stress, silicon also increased shoot dry weight in TN-04-107, TN-04-70, TN-04-37, Payam and Sepideh genotypes

Hourly zonal (u) and meridional (v) wind components were retrieved from hindcast regional climate simulation covering the whole Iberian Peninsula (IP) with a spatial resolution of 9 km. This simulation was performed with the WRF model and for this study, the u and v components were extracted for a set of 12 points of the simulation grid around Lisbon. The preliminary results regarding the average daily critical transport indices for the 1989-2007 period clearly indicate that the airshed is prone to ventilation as these events have a dominant presence through most of the study period (72%), relatively to the occurrence of recirculation (10%) and stagnation (<2%) events. Comparatively to the 1989-2007 period, the 2014 episode is truly exceptional. [1] Allwine KJ, Whiteman CD., 1994. Atmospheric Environment 28: 713-721. [2] Blystad H, Brantsæter AB, Løvoll Ø., 2005.

The PPARγ-signaling pathway is involved in the anticancer effects of carotenoids. Activation of PPARγ partly contributes to the growth-inhibitory effects of carotenoids (β-carotene, astaxanthin, bixin, capsanthin, lutein, and lycopene on breast cancer MCF7 cells, leukemia K562 cells, prostate cancer (LNCaP, DU145, and PC3 cells, and esophageal squamous cancer EC109 cells. PPARγ is the master regulator of adipocyte differentiation and adipogenesis. Downregulated PPARγ and PPARγ-target genes have been associated with the suppressive effects of β-carotene and lycopene on 3T3L1 and C3H10T1/2 adipocyte differentiation and adipogenesis. ß-Carotene is cleaved centrally into retinaldehyde by BCO1, the encoding gene being a PPARγ-target gene. Retinaldehyde can be oxidized to retinoic acid and also be reduced to retinol. β-Carotene can also be cleaved asymmetrically into β-apocarotenals and β-apocarotenones by BCO2. The inhibitory effects of β-carotene on the development of adiposity and lipid storage are dependent substantially on BCO1-mediated production of retinoids. The effects of β-carotene on body adiposity were absent in BCO1-knockout mice. Retinoid metabolism is connected with the activity of PPARγ in the control of body-fat reserves. Retinoic acid, retinaldehyde, retinol, and β-apocarotenals exert suppressive effects on preadipocyte differentiation and adipogenesis via downregulation of PPARγ expression in cell culture. The

While Ad5 can be robust, species C Ad6 has lower seroprevalence, side effects, and appears to be more potent as a systemic therapy against a number of tumors than Ad5. Historically, there have only been four species C human adenoviruses: serotypes 1, 2, 5, and 6. More recently a new species C adenovirus, Ad57, was identified. Ad57 is most similar to Ad6 with virtually all variation in their capsid proteins occurring in the hypervariable regions (HVRs of their hexon proteins. Most adenovirus neutralizing antibodies target the HVRs on adenoviruses. This led us to replace the hexon HVRs in Ad6 with those from Ad57 to create a new virus called Ad657 and explore this novel species C platform’s utility as an oncolytic virus. Methods: The HVR region from Ad57 was synthesized and used to replace the Ad6 HVR region by homologous recombination in bacteria generating a new viral platform that we call Ad657. Replication-competent Ad5, Ad6, and Ad657 were compared in vitro and in vivo for liver damage and oncolytic efficacy against prostate cancers after single intravenous treatment in mice. Results: Ad5, Ad6, and Ad657 had similar in vitro oncolytic activity against human prostate cancer cells. Ad5 provoked the highest level of liver toxicity after intravenous injection and Ad657

    Organic nitrates (ON = RONO2 + RO2NO2) are an important reservoir, if not sink, of atmospheric nitrogen oxides (NOx=NO+NO2). ON formed from isoprene oxidation alone are responsible for the export of 8 to 30% of anthropogenic NOx out of the U.S. continental boundary layer [Horowitz et al., 1998; Liang et al., 1998]. Regional NOx budgets and tropospheric ozone (O3) production, are therefore particularly sensitive to uncertainties in the yields and fates of ON [Beaver et al., 2012; Browne et al., 2013]. The yields implemented in modeling studies are determined from laboratory experiments in which only a few of the first generation gaseous ON or the total gas and particle-phase ON have been quantified [Perring et al., 2013 and references therein], while production of highly functionalized ON capable of strongly partitioning to the particle-phase have been inferred [Farmer et al., 2010; Ng et al., 2007; Nguyen et al., 2011; Perraud et al., 2012; Rollins et al., 2012], or directly measured [Ehn et al., 2014]. Addition of a nitrate (–ONO2) functional group to a hydrocarbon is estimated to lower the equilibrium saturation vapor pressure by 2.5 to 3 orders of magnitude [e.g. Capouet and Muller, 2006]. Thus, organic nitrate formation can potentially enhance particle-phase partitioning of hydrocarbons in regions with elevated levels of nitrogen oxides, contributing to secondary organic aerosol (SOA) formation [Ng et al., 2007]. There has, however, been no high time-resolved measurements of speciated ON in the particle-phase. We utilize a newly developed high-resolution time-of-flight chemical ionization mass spectrometer (HR-ToF-CIMS) using Iodide-adduct ionization [B H Lee et al., 2014a] with a filter inlet for gases and aerosols (FIGAERO) [Lopez-Hilfiker et al., 2014] that allows alternating in situ measurement of the molecular composition of gas and particle phases. We present observations of speciated ON in the particle-phase obtained during the 2013 Southern Oxidant

En outre, au niveau psycholinguistique, ils apportent des données intéressantes dans le débat qui oppose les tenants de l’approche abstractionniste à ceux de l’approche exemplariste, en favorisant plutôt la deuxième approche ou une approche intermédiaire, très en vogue actuellement, celle des modèles hybrides (Nguyen, Wauquier et Tuller, 2009.

To address this issue, we investigated whether ZnO NPs with different size (20 or 100 nm and electrostatic charge (positive or negative would cause immunotoxicity in vitro and in vivo, and explored their underlying molecular mechanism. Using Raw 264.7 cell line, we examined the immunotoxicity mechanism of ZnO NPs as cell viability. We found that in a cell viability assay, ZnO NPs with different size and charge could induce differential cytotoxicity to Raw 264.7 cells. Specifically, the positively charged ZnO NPs exerted higher cytotoxicity than the negatively charged ones. Next, to gauge systemic immunotoxicity, we assessed immune responses of C57BL/6 mice after oral administration of 750 mg/kg/day dose of ZnO NPs for 2 weeks. In parallel, ZnO NPs did not alter the cell-mediated immune response in mice but suppressed innate immunity such as natural killer cell activity.

    test the dynamics and energetics of the numerical model, but also to advance the analysis based on combined wavelet and empirical orthogonal function. In particular, we focus on the study of the transient regime of internal wave generation near the ridge. Our analyses of the experimental fields show that, for fixed background stratification and topography, the evolution of the stratification anomaly strongly depends on the forcing frequency. The duration of the transient regime, as well as the amplitude reached in the stationary state vary significantly with the parameter ω/N (where ω is the forcing frequency, and N is the background Brunt-Väisälä frequency). We also observe that, for particular forcing frequencies, for which the ridge slope matches the critical slope of the first harmonic mode, internal waves are excited both at the fundamental and the first harmonic frequency. Associated energy transfers are finally evaluated both experimentally and numerically, enabling us to highlight the similarities and discrepancies between the laboratory experiments and the numerical simulations.

    case study), following the approach proposed by Ntegeka et al. (2014). When the consequences of given scenarios are high, they should be taken into account in the decision making process. For the Flanders' guidelines, it was agreed among the members of the regional Coordination Commission Integrated Water Management to consider (in addition to the traditional range of return periods up to 5 years) a 20-year design storm for scenario investigation. It was motivated by the outcome of this study that under the high climate scenario a 20-year storm would become - in order of magnitude - a 5-year storm. If after a design for a 5-year storm, the 20-year scenario investigation would conclude that specific zones along the sewer system would have severe additional impacts, it is recommended to apply changes to the system or to design flexible adaptation measures for the future (depending on which of the options would be most cost-efficient). Another adaptation action agreed was the installation of storm water infiltration devices at private houses and make these mandatory for new and renovated houses. Such installation was found to be cost-effective in any of the climate scenario's. This is one way of dealing with climate uncertainties, but lessons learned from other cases/applications are highly welcomed. References Ntegeka, V., Baguis, P., Roulin, E., Willems, P.

    I worked on several projects this term. While most projects involved additive manufacturing, I was also involved with two design projects, two testing projects, and a fabrication project. The primary mentor for these was Richard Hagen. Secondary mentors were Hai Nguyen, Khadijah Shariff, and fabrication training from James Brown. Overall, my experience at JSC has been successful and what I have learned will continue to help me in my engineering education and profession long after I leave. My 3D printing projects ranged from less than a 1 cubic centimeter to about 1 cubic foot and involved several printers using different printing technologies. It was exciting to become familiar with printing technologies such as industrial grade FDM (Fused Deposition Modeling), the relatively new SLA (Stereolithography), and PolyJet. My primary duty with the FDM printers was to model parts that came in from various sources to print effectively and efficiently. Using methods my mentor taught me and the Stratasys Insight software, I was able to minimize imperfections, hasten build time, improve strength for specific forces (tensile, shear, etc...), and reduce likelihood of a print-failure. Also using FDM, I learned how to repair a part after it was printed. This is done by using a special kind of glue that chemically melts the two faces of plastic parts together to form a fused interface. My first goal with SLA technology was to bring the printer back to operational readiness. In becoming familiar with the Pegasus SLA printer, I researched the leveling, laser settings, and different vats to hold liquid material. With this research, I was successfully able to bring the Pegasus back online and have successfully printed multiple sample parts as well as functional parts. My experience with PolyJet technology has been focused on an understanding of the abilities/limits, costs, and the maintenance for daily use. Still upcoming will be experience with using a composite printer that uses FDM

    scientific community by showing the current state-of-the-art research opportunities using the RMC method. Furthermore, by including a small number of papers from colleagues working on similar disordered problems with complementary analysis techniques, we hope that the RMC method may be placed in a broader scientific context. The papers have been arranged in order of increasing structural disorder, starting with studies of crystalline systems, through to amorphous materials and liquids, and ending with RMC developments using small-angle scattering. We are very grateful to IOP Publishing for their willingness to publish this collection of papers which celebrates the 21st anniversary of the first RMC publication in a special issue of Journal of Physics: Condensed Matter and for their co-ordination of the refereeing process.

    Full text: Distinguished Ministers, Excellencies, Ladies and Gentlemen, I am very pleased to welcome you to the 2012 IAEA Scientific Forum. I especially thank Secretary Chu, Minister Margaret Kamar, Minister Nguyen Quan and Director General Haryana for agreeing to participate in this opening session. I thank Mr. Jose Graziano da Silva, Director General of the FAO, for his video message. I also welcome the many scientists and technologists who have come to share their expertise with us. When I am asked why I decided to focus on food at this year's Scientific Forum, my answer is simple: there are nearly one billion people on this planet who do not have enough to eat. All of us have a responsibility to do everything we can to help them. The IAEA is in the unique position of being able to make nuclear technology available to developing countries. We help them to grow more food, fight animal and plant pests and diseases, and ensure the safety of food products. Nuclear technology makes a powerful and critical contribution. Working closely with our partners at the UN Food and Agriculture Organization, the IAEA supports over 200 projects in more than 100 countries. You saw some examples in the film a moment ago. I hope that this IAEA Scientific Forum will encourage countries already familiar with nuclear techniques related to food to make more use of them. And I hope more countries will take advantage of the Agency's services in this area. Ladies and Gentlemen, I would like to follow up on some of the examples of our work which you saw in the film. [HOLD UP MANDARIN] This mandarin comes from a region of Croatia where 90 percent of the people are involved in the citrus fruit industry. The value of citrus production in this area is estimated at around 30 million euros a year. However, around a third of the annual crop is destroyed by fruit flies. We therefore deployed the Sterile Insect Technique. It is essentially a form of birth control. Millions of male flies are

    researchers in the HU CFRT mentor the students during summers. Mentors spend a considerable amount of time and efforts in training, teaching, guiding and supervising research projects. The HU CFRT has so far conducted nine workshops during the summers of 1996-2000 and 2002-2005. The first workshop was conducted in summer 1996. Students for the workshop are chosen from a national pool of exceptionally talented high school rising seniors/juniors. To our knowledge, most of these students have gone on to prestigious universities such as Duke University, John Hopkins University, CalTech, UCLA, Hampton University, etc. after completing their high school. For instance, Tiffany Fisher, participant of the 1996 summer workshop completed her BS in Mathematics at Hampton University in May 2001. She then went on to Wake Forest University at Winston-Salem, North Carolina to pursue graduate studies. Anshul Haldipur, participant of the 1999 summer workshop, began his undergraduate studies at Duke University in 2000. Christina Nguyen and Ilissa Martinez, participants of the 2000 summer workshop, are pursuing their undergraduate degrees at the UCLA and Florida State University respectively. The organizing committee of the APS DPP annual meeting invited Dr. Punjabi to deliver an invited talk on training the next generation of fusion scientists and engineers at the 2005 APS DPP meeting in Denver, CO. The organizing committee distributed a special flier with the Bulletin to highlight this invited talk and another talk on education as well the expo. This has given wide publicity and recognition to our workshops and Hampton University. Prof. Punjabi's talk: 'LI2 2: Training the next generation of fusion scientists and engineers: summer high school fusion science workshop, Bull. Amer. Phys. Soc. 50, 221 (2005)' was very well-received. He talked about HU education and outreach initiative and the HU CFRT Summer High School Workshop. The audience had a considerable number of questions about our

    Since the publication of the DSM-5 (APA, 2013), the dimensional conception of the personality disorders is co-existing with the classical categorical paradigm. Tools have been proposed for the evaluations of five big pathological factors to be explored further according to the APA (negative affectivity, detachment, antagonism, disinhibition, psychoticism). Despite numerous works using these questionnaires (30 works in 3 years according to Al-Adjani et al., 2015), none of them have yet been translated into French. Also, the main objective of the paper is to present a French translation of the Personality Inventory for DSM -5 by Kruegger et al. (2013) in its brief form of 25 items (PID-5 BF). To reach this goal, we have employed the classic translation-retranslation method (Vallerand, 1989) and tested the consistence and the validity of this French version among a non-clinical sample (n=216) of young adults (age=31.4, SD=4.8), in joining some other questionnaires in their short forms to study the external validity of the PID-5 about the psychological distress (SCL-10, Nguyen, 1983), the categorical diagnosis of personality disorders (SAPAS, Moran et al., 2003) and the classical Big Five dimensions of the personality (BDI 10, Ramamstedt and John, 2007). The internal consistency of this translation has been studied through the classical outcomes on factor analysis for the dimensional repartitions of the items in 5 scales and Cronbach's alpha for the consistency of each found dimensions. The external validity has been explored by studying Pearson's correlations between the outcomes on each dimension of the PID-5 BF and both the clinical dimensions of SCL-10, personality dimensions of the BFI-10 or personality disorders (SAPAS). Factor analysis led to the same repartition of the 25 items as the original versions. Each of the dimensions is consistent enough (α>.65) to be taken into account as clinically significant. The items of the French version of the PID-5 BF follow

    g soil). The glucose was added together with nutrient solution, containing N, P and K. After glucose addition the soil moisture increased up to 70% WHC. Soil samples without glucose amendment were used as a control treatment. After treatment with glucose soil samples were incubated for 14 days at 22 °C. The produced CO2 was trapped in 0.45 ml of 1 M NaOH solution. The amount of evolved total CO2 was analysed by titration of an aliquot of the NaOH solution with 0.1 M HCl after precipitation of the trapped CO2 as BaCO3. The activity of 14CO2 trapped in the NaOH solution was measured with a Liquid Scintillation Counter (Microbeta, Perkin Elmer) after mixing of the aliquot NaOH solution with 0.5 ml of the scintillation cocktail Rotiszint Eco Plus. Combination of treatments with 14C labeled plant residues and 14C labeled glucose allowed calculation of (1) the effect of glucose on SOM decomposition, and (2) the effect of glucose on plant residues decomposition. The glucose was consumed within one day after addition. Similar results were obtained also in other studies (Nguyen and Honrz, 2002). The maximal rate of glucose mineralization was measured within the first day and was three times higher in soil without plant residues (43% and 15% of input for low and high glucose amount, respectively). Our estimation of the proportion of 14C-CO2 evolved from glucose was very close to that by Šantruckova et al. (2004). They found 27% of 14C evolved as CO2 after 72 h of aerobic incubation of soil with 315 µg glucose-C g-1. Twelve days after glucose addition 47.2 and 32.8% of the added glucose was mineralized to CO2 for low and high glucose amount, respectively. Both concentrations of glucose increased SOM decomposition and increased maize residue decomposition compared to the control without glucose. The apparent PE observed under C-limiting conditions after the addition of small glucose amount can be explained by the "signal" or "triggering" effect. The addition of easily

Relative water content (RWC of the leaves was appraised as described by Ritchie and Nguyen (19 using the following formula: RWC (% = [(f. wt. – d. wt. / (t. wt. – d. wt.] × 100 Where f. wt, d. wt and t. wt are fresh weight, dry weight and turgid weight, respectively. Diameter and length of fruit were measured by nondestructive method (on the tree and by using digital caliper in the places of maximum length and maximum width diameters, and length: diameter ratio from the division of these two parameters. Fruit weight was estimated by digital scale (0.01 g and its volume by the difference of the water level of scaled column, and then fruit density was calculated by using formula d=M/V. In order to estimate the parameters of leaf area, specific leaf area and specific leaf weight, leaf area meter and oven were used. To evaluate the effect of the treatments on decrease or increase current shoot growth, measuring shoot length was reported by tape measure according to centimeter. Results and Discussion: The results indicated that the most amount of specific leaf weight was allocated in chelated magnesium sulfate (0.5 and 0.7 g: 1000 ml treatments and the least amount was belonged to the control group. The extent of changes in leaf area was between 28.17 to 44.33 cm2, were recorded to control group (without water and salicylic acid (0.1 g: 1000 ml plus chelated magnesium sulfate (0.7 g: 1000 ml, respectively. The minimum and maximum of specific leaf area were ranged between 44.14 to 59.40 cm2 and belonged to control group (without water and salicylic acid (0.1 g: 1000 ml, respectively. The most current shoot growth was observed in control group (without water and the least quantity was in chelated magnesium sulfate (0.5 g: 1000 ml. The minimum and maximum of fresh weight of leaf was changeable between 1.513 to 1.94 g were recorded to control group and salicylic acid (0.1 g: 1000 ml plus chelated magnesium sulfate (0.7 g: 1000 ml, respectively.
