    Objective: To assess the nutritional status of school going children in Rural Block Hajin. Methods: School children from various primary and middle level educational facilities from a rural health block were surveyed during the School Health Program. Height and weight was measured following standard procedures. MS Excel and Interactive statistics page were used for analysis of data. Results: Both mean weight and height were higher in females than males. The overall prevalence of under nutrition was 19.2%. The prevalence of underweight was lowest in 5 year female (0.0%) and highest in 6 year male (21.5%). For Stunting 7 year males recorded the lowest (0.0%) and 12 year males the highest (28.5%) prevalence. The highest and lowest prevalence of wasting was recorded in 6 year old females (2.56%) and 9 year old males (24.6%) respectively. Prevalence of thinness was lowest in 13 year old females (14.2%) and highest in 13 year old males (47.1%).Conclusion: The nutritional status of school age children in this health block are comparatively better even though a large number of children still fall below the cutoff for various nutritional indicators

    In the present era, the renewable sources of energy, e.g., piezoelectric materials are in great demand. They play a vital role in the field of micro-electromechanical systems, e.g., sensors and actuators. The cantilever-based piezoelectric energy harvesters are very popular because of their high performance and utilization. In this research-work, an energy harvester model based on a cantilever beam with bimorph PZT-5A, having a substrate layer of structural steel, was presented. The proposed energy scavenging system, designed in COMSOL Multiphysics, was applied to analyze the electrical output as a function of excitation frequencies, load resistances and accelerations. Analytical modeling was employed to measure the output voltage and power under pre-defined conditions of acceleration and load resistance. Experimentation was also performed to determine the relationship between independent and output parameters. Energy harvester is capable of producing the maximum power of 1.16 mW at a resonant frequency of 71 Hz under 1g acceleration, having load resistance of 12 k Omega. It was observed that acceleration and output power are directly proportional to each other. Moreover, the investigation conveys that the experimental results are in good agreement with the numerical results. The maximum error obtained between the experimental and numerical investigation was found to equal 4.3%

    Sparticle Spectrum Constraints

    The supersymmetric standard model with supergravity-inspired soft breaking terms predicts a rich pectrum of sparticles to be discovered at the SSC, LHC and NLC. Because there are more supersymmetric particles than unknown parameters, one can write down sum rules relating their masses. We discuss the pectrum of sparticles from this point of view. Some of the sum rules do not depend on the input parameters and can be used to test the consistency of the model, while others are useful in determining the input parameters of the theory. If supersymmetry is discovered but the sum rules turn out to be violated, it will be evidence of new physics beyond the minimal supersymmetric standard model with universal soft supersymmetry-breaking terms.Comment: 25 pages.

    An Occupational Disease was a disease caused by work or work environment. One of the efficient and effective strategies for controlling Occupational Disease was the empowerment and participation of the community called Occupational Health Unit (Pos UKK) in the workplace. Based on the data of market health inspection in Pos UKK Imogiri market in March 2017, there were only 67 participants (19.17%) from 365 invited people.: The purpose of this research was to know the internal factors with the community participation in Pos UKK Imogiri market Bantul. This research was a quantitative analytic research with cross sectional design. The population was 365 people and the sample was 150 respondents. The sampling used purposive sampling technique. Kendall Tau test showed that there was a relation between perception and community participation (p value <0.05, r = 0.677); Intentions related to community participation (p value <0.05 r = 0.486); Attitudes related to community participation (p value <0.05 , r= 0.802). F test result showed that the variables of Perception, Intentions and Attitudes related simultaneously to community participation (F value = 387.41> F table = 2.67). The dominant independent variable was Attitudes with the highest Standard Beta Coefficient value was 0.776. Perceptions, Intentions and Attitudes related both partially and simultaneously to community participation; the independent variable that had dominant influence was Attitudes

    Electron Glass Dynamics

    Examples of glasses are abundant, yet it remains one of the phases of matter whose understanding is very elusive. In recent years, remarkable experiments have been performed on the dynamical aspects of glasses. Electron glasses offer a particularly good example of the 'trademarks' of glassy behavior, such as aging and slow relaxations. In this work we review the experimental literature on electron glasses, as well as the local mean-field theoretical framework put forward in recent years to understand some of these results. We also present novel theoretical results explaining the periodic aging experiment.Comment: Invited review to appear in Annual Review of Condensed Matter Physic

    Casimir effect of electromagnetic field in Randall-Sundrum spacetime

    Full text link
    We study the finite temperature Casimir effect on a pair of parallel perfectly conducting plates in Randall-Sundrum model without using scalar field analogy. Two different ways of interpreting perfectly conducting conditions are discussed. The conventional way that uses perfectly conducting condition induced from 5D leads to three discrete mode corrections. This is very different from the result obtained from imposing 4D perfectly conducting conditions on the 4D massless and massive vector fields obtained by decomposing the 5D electromagnetic field. The latter only contains two discrete mode corrections, but it has a continuum mode correction that depends on the thicknesses of the plates. It is shown that under both boundary conditions, the corrections to the Casimir force make the Casimir force more attractive. The correction under 4D perfectly conducting condition is always smaller than the correction under the 5D induced perfectly conducting condition. These statements are true at any temperature.Comment: 20 pages, 4 figure

    Semi-invariants of symmetric quivers of finite type

    Let (Q,σ)(Q,\sigma) be a symmetric quiver, where Q=(Q0,Q1)Q=(Q_0,Q_1) is a finite quiver without oriented cycles and σ\sigma is a contravariant involution on Q0⊔Q1Q_0\sqcup Q_1. The involution allows us to define a nondegenerate bilinear form on a representation $V$ of $Q$. We shall call the representation orthogonal if is symmetric and symplectic if is skew-symmetric. Moreover we can define an action of products of classical groups on the space of orthogonal representations and on the space of symplectic representations. For symmetric quivers of finite type, we prove that the rings of semi-invariants for this action are spanned by the semi-invariants of determinantal type cVc^V and, in the case when matrix defining cVc^V is skew-symmetric, by the Pfaffians pfVpf^V

    Decay of low-lying 12C resonances within a 3alpha cluster model

    Full text link
    We compute energy distributions of three α\alpha-particles emerging from the decay of 12^{12}C resonances by means of the hyperspherical adiabatic expansion method combined with complex scaling. The large distance continuum properties of the wave functions are crucial and must be accurately calculated. The substantial changes from small to large distances determine the decay mechanisms. We illustrate by computing the energy distributions from decays of the 1+1^{+} and 3−3^--resonances in 12^{12}C. These states are dominated by direct and sequential decays into the three-body continuum respectively.Comment: 5 pages, 3 figures.
