    The study has been undertaken to document the nutritional status of school going children among Bangalore’s Urban Poor and to document the factors influencing it. The three anthropometric measures namely wasting, stunting and underweight is used to understand the level of malnutrition in children. The main focus of the study is to document the nutrition status of children from poor urban households through the anthropometric measures, to analyse the socio economic factors like gender and income and their impact on nutritional status. The data was collected from a sample of households drawn from Bangalore’s slums and was drawn using cluster sampling. Moderate levels of stunting is seen in majority of households and also across both gender, slightly higher with the female children and it was found predominant in small and large families across all categories of caste. The Gomez index measuring nutrition based on weight for age found small percentage of children with mild form of malnutrition across income and gender groups. Gomez analysis also found that with increase in family size the level of malnutrition, which is strengthened through the logistic regression. Wasting was also found at moderate levels in more than fifty percent of the households. logistic regression was used to analyse the factors influencing economic development revealed that the age of the child and family size were deterrent factors affect nutrition levels

    Objectives: to describe a bench model (workshop of abilities) for sinus floor elevation (SFE) training that simulates the surgical environment and to assess its effectiveness in terms of trainees? perception. Study design: thirty-six randomly selected postgraduate students entered this cross-sectional pilot study and asked to fill in an anonymous, self-applied, 12-item questionnaire about a SFE workshop that included a study guide containing the workshop?s details, supervised practice on a simulated surgical environment, and assessment by means of specific check-lists. Results: Thirtiy-six fresh sheep heads were prepared to allow access to the buccal vestible. Using the facial tuber, third premolar and a 3D-CT study as landmarks for trepanation, the sinus membrane was lifted, the space filled with ceramic material and closed with a resorbable membrane. The participants agreed on their ability to perform SFE in a simulated situation (median score= 4.5; range 2-5) and felt capable to teach the technique to other clinicians or to undertake the procedure for a patient under supervision of an expert surgeon (median= 4; range 1-5 ). There were no differences on their perceived ability to undertake the technique on a model or on a real patient under supervision of an expert surgeon (p=0.36). Conclusions: Clinical abilities workshops for SFE teaching are an essential educational tool but supervised clinical practice should always precede autonomous SFE on real patients. Simulation procedures (workshop of abilities) are perceived by the partakers as useful for the surgical practice. However, more studies are needed to validate the procedure and to address cognitive and communication skills, that are clearly integral parts of surgical performance

    “Re-Culturing” Teacher Education: Inquiry, Evidence, and Action

    Currently the press to make policy and practice decisions on the basis of evidence is being coupled with recognition that real change requires shifts in organizational culture. Consequently, there are now many efforts to “re-culture” organizations by making evidence central to decision making. In this article, the authors problematize the notion of a “culture of evidence” in teacher education. Then the article identifies four key aspects involved in efforts to create a culture of evidence at one institution over a five-year period: (1) development of a portfolio of studies about processes and outcomes; (2) recognition that teacher education always poses values questions as well as empirical questions; (3) an exploratory, open-ended approach to evidence construction; and, (4) multiple structures that institutionalize evidence collection and use locally and beyond. The authors suggests that building cultures of evidence has the potential to be transformative in teacher education, but only if challenges related to sustainability, complexity, and balance are addressed

    On the Deformation of Dendrites During Directional Solidification of a Nickel-Based Superalloy

    Abstract: Synchrotron X-ray imaging has been used to examine in situ the deformation of dendrites that takes place during the solidification of a nickel-based superalloy. By combining absorption and diffraction contrast imaging, deformation events could be classified by their localization and permanence. In particular, a deformation mechanism arising from thermal contraction in a temperature gradient was elucidated through digital image correlation. It was concluded that this mechanism may explain the small misorientations typically observed in single crystal castings

    CD27 sustains survival of CTLs in virus-infected nonlymphoid tissue in mice by inducing autocrine IL-2 production

    Immunity to infections relies on clonal expansion of CD8+ T cells, their maintenance as effector CTLs, and their selection into a memory population. These processes rely on delivery of survival signals to activated CD8+ T cells. We here reveal the mechanism by which costimulatory CD27-CD70 interactions sustain survival of CD8+ effector T cells in infected tissue. By unbiased genome-wide gene expression analysis, we identified the Il2 gene as the most prominent CD27 target gene in murine CD8+ T cells. In vitro, CD27 directed IL-2 expression and promoted clonal expansion of primed CD8+ T cells exclusively by IL-2–dependent survival signaling. In mice intranasally infected with influenza virus, Cd27–/– CD8+ effector T cells displayed reduced IL-2 production, accompanied by impaired accumulation in lymphoid organs and in the lungs, which constitute the tissue effector site. Reconstitution of Cd27–/– CD8+ T cells with the IL2 gene restored their accumulation to wild-type levels in the lungs, but it did not rescue their accumulation in lymphoid organs. Competition experiments showed that the IL-2 produced under the control of CD27 supported effector CD8+ T cell survival in the lungs in an autocrine manner. We conclude that CD27 signaling directs the IL-2 production that is reportedly essential to sustain survival of virus-specific CTLs in nonlymphoid tissue

    Classifying Software Component Interoperability Errors to Support Component Adaption

    No full text
    Abstract. This paper discusses various classifications of component interoperability errors. These classifications aim at supporting the automation of component adaptation. The use of software components will only demonstrate beneficial, if the costs for component deployment (i.e., acquisition and composition) are considerably lower than those for custom component development. One of the main reasons for the moderate progress in component-based software engineering are the high costs for component deployment. These costs are mainly caused by adapting components to bridge interoperability errors between unfitting components. One way to lower the costs of component deployment is to support component adaptation by tools, i.e., for interoperability checks of (semi-)automated adaptor generation. This automation of component adaptation requires a deep understanding of component interoperability errors. In particular, one has to differentiate between different classes of interoperability errors, as different errors require different adaptors for resolving. Therefore, the presented classification of component interoperability errors supports the automation of component adaptation by aiding automated interoperability problem detection and semi-automated adaptor generation. The experience gained from already implemented solutions for a specific class of interoperability errors provides hints for the solution of similar problems of the same class.
