Food Security and Nutritional Status among Rural Poor: Evaluating the Impact of Rural Livelihood Mission in Odisha, India

This paper empirically examines the effect of participation in National Rural Livelihood Mission (NRLM) on the food security of rural poor. In parallel, it also introspects the nutritional profiles of the respondents. Data were collected from 220 respondents (including both beneficiaries and non-beneficiaries) through a structured questionnaire from Sonepur district of Odisha (India). For assessing the nutritional profile, the study uses 24 hour recall and food frequency questionnaire methods to collect the information on food consumption. Then food items were converted into their equivalent calories. A food security index (FSI) was constructed to capture the food security taking the average calories of food consumed by the respondents. The study finds a better food consumption pattern among beneficiaries than the non-beneficiaries. Further, the impact of NRLM is examined using randomised control trial method and finds a positive impact of the programme on the food security. That means, participation in the programme helps the beneficiaries to attain food security. Therefore, participation should be encouraged to mitigate the food insecurity problem

Load balancing and power factor correction in power distribution system

The project presents an approach for load balancing and power factor correction. First we have considered a three phase grounded load system where the supply is a three phase balanced supply. Before balancing the load and correcting the power factor it is necessary to compensate the neutral current. We propose three schemes for neutral current balancing. After that the system becomes equivalent to ungrounded star connected load. Now to carry power factor correction and load balancing we need to convert the load to delta connected load. Hence we carry out star-delta transformation and we carry out our main objective through the proposed methods

Capacity building among frontline health workers (FHWs) in screening for cardiovascular diseases (CVDs): Findings of an implementation study from Bihar, India

Background: Community-based screening is one of the key preventive strategies to tackle the ever-rising burden of non-communicable diseases (NCDs) under the National Programme for Prevention & Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke (NPCDCS). Objective: The current study was aimed to build capacity among frontline health workers (FHWs) in screening for cardiovascular diseases (CVDs) under NPCDCS in the selected districts of Bihar state. Methodology: This was an implementation study with follow-up components, conducted among 75 FHWs [14 auxiliary nurse midwives (ANMs) and 61 accredited social health activists (ASHAs)] from 15 primary healthcare facilities across four districts of Bihar state from October 2019 to September 2021. The selected FHWs were initially trained on NPCDCS for a day, including pre- and post-training knowledge assessment. Then, supportive supervision (SS) visits using a predesigned questionnaire were done. Results: The pre- and post-training mean knowledge scores of the FHWs were 12.9 and 22.1, respectively, with an overall effect size of 2.5. During SS visits, only 20.0% of the visited primary healthcare facilities had all the required logistics to conduct weekly NCD screening clinics for CVDs. Considering different measurements and operative skill proficiencies of FHWs, waist circumference skills (41.7% for ANMs and 50.8% for ASHAs), followed by blood pressure (BP) (41.7%) and random blood sugar (RBS) measurement (25.0%), were found to be the most deficient skills (among ANMs). Moreover, the quality of initial and follow-up home visits was found to be satisfactory for only 54.1% of the ASHAs. The reported barriers of NCD screening were reported to be non-cooperation, unawareness among community dwellers, lack of knowledge and skill of FHWs, logistic constraints and delayed honorarium credit. Conclusion: One-day training on NCDs for FHWs was quite effective. However, for translating all the desired skills for CVD screening into action, periodic training needs assessment, and SS of FHWs might be fruitful

Studies of multiferroic palladium perovskites

Work at St. Andrews supported by EPSRC grant EP/P024637/1; at Queens University Belfast by EPSRC Grant No. EP/J017191/1 and EP/N018389/1, at Univ. Puerto Rico by DoD AFOSR Grant FA9550-16-1-0295 and at West Virginia University by DOE (DE-SC0016176).We have studied the atomic force microscopy (AFM), X-ray Bragg reflections, X-ray absorption spectra (XAS) of the Pd L-edge, Scanning electron microscopey (SEM) and Raman spectra, and direct magnetoelectric tensor of Pd-substituted lead titanate and lead zirconate-titanate. A primary aim is to determine the percentage of Pd+4 and Pd+2 substitutional at the Ti-sites (we find that it is almost fully substitutional). The atomic force microscopy data uniquely reveal a surprise: both threefold vertical (polarized out-of-plane) and fourfold in-plane domain vertices. This is discussed in terms of the general rules for Voronoi patterns (Dirichlet tessellations) in two and three dimensions. At high pressures Raman soft modes are observed, as in pure lead titanate, and X-ray diffraction (XRD) indicates a nearly second-order displacive phase transition. However, two or three transitions are involved: First, there are anomalies in c/a ratio and Raman spectra at low pressures (P = 1 − 2 GPa); and second, the c/a ratio reaches unity at ca. P = 10 GPa, where a monoclinic (Mc) but metrically cubic transition occurs from the ambient tetragonal P4 mm structure in pure PbTiO3; whereas the Raman lines (forbidden in the cubic phase) remain until ca. 17 GPa, where a monoclinic-cubic transition is known in lead titanate.Publisher PDFPeer reviewe

Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

The results are compared to several theoretical calculations and to previous measurements.Peer reviewe

Combined searches for the production of supersymmetric top quark partners in proton-proton collisions at root s=13 TeV

A combination of searches for top squark pair production using proton-proton collision data at a center-of-mass energy of 13 TeV at the CERN LHC, corresponding to an integrated luminosity of 137 fb(-1) collected by the CMS experiment, is presented. Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on themodel, the combined result excludes a top squarkmass up to 1325 GeV for amassless neutralino, and a neutralinomass up to 700 GeV for a top squarkmass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV

Measurement of the top quark forward-backward production asymmetry and the anomalous chromoelectric and chromomagnetic moments in pp collisions at √s = 13 TeV

Abstract The parton-level top quark (t) forward-backward asymmetry and the anomalous chromoelectric (d̂ t) and chromomagnetic (μ̂ t) moments have been measured using LHC pp collisions at a center-of-mass energy of 13 TeV, collected in the CMS detector in a data sample corresponding to an integrated luminosity of 35.9 fb−1. The linearized variable AFB(1) is used to approximate the asymmetry. Candidate t t ¯ events decaying to a muon or electron and jets in final states with low and high Lorentz boosts are selected and reconstructed using a fit of the kinematic distributions of the decay products to those expected for t t ¯ final states. The values found for the parameters are AFB(1)=0.048−0.087+0.095(stat)−0.029+0.020(syst),μ̂t=−0.024−0.009+0.013(stat)−0.011+0.016(syst), and a limit is placed on the magnitude of | d̂ t| &lt; 0.03 at 95% confidence level.
