Knowledge And Attitudes of Anganwadi Workers About Breast Feeding in The Field Practice Area of Tertiary Care Hospital, Hyderabad
No full textBackground: Breast feeding is one of the most important determinants of child survival, birth spacing and prevention of childhood infections. It is important for the Anganwadi workers to have adequate scientific knowledge about breast feeding practices. . Hence this study was conducted to assess the knowledge and attitude of AWW with regards to breast feeding practices.
Methodology: A facility based cross sectional study was conducted covering all 68 ICDS centers. A pretested semi-structured questioner was given to all AWWs. All questions were read out and explained by the author and all queries were clarified.
Results: only 70 % AWW believed that breast feeding should be given on demand and 75 % AWWs believed that bottle is better than katori & spoon for infant feeding. 40% said breastfeeding should be stopped if mother is sick. Most of AWW (98%) believed that almonds and dry fruits increase breast milk secretion.
Conclusion: Present research draws very important conclusions that although knowledge of AWW regarding initiation of breast feeding is high but their knowledge regarding prelecteal feeds, feeding on demand, bottle feeding and breast feeding during sickness needs further improvement
Industrial applications of X-Ray Photoelectron Spectroscopy (XPS) in India
No full textThis review paper summarizes the industrial applications of XPS in India from open literature. Many industrial research and development centers in India, except for a few, do not have in-house XPS systems, and leverage either the instruments available at many government laboratories or universities across various locations in India, or their in-house instruments in other parts of the world for their research activities. While XPS is being used for a wide range of applications, based on an exhaustive literature search by the author, an understanding of the scientific basis of the technique as well as related analytical techniques such as X-ray Excited Auger Electron Spectroscopy (XAES) and depth profiling, the instrumentation, the measurement, and interpretation of the results could be improved. This could potentially avoid artifacts as well as misinterpretation of results. This paper also highlights a few key points that must be considered while measuring and interpreting XPS data

No full textA Study to Assess the Obesity and Its Determinants Among School Going Adolescents in Hyderabad
No full textBackground: Obesity, once considered a problem of developed countries, is now growing enormously in many developing countries also. Changes in diet and physical activity raise the prevalence of obesity in children.
Methodology: A cross sectional study was conducted among students of standard VIII – X in Hyderabad. Schools were selected from list of schools randomly. Total 763 children were included in study. Pre-tested questionnaires were used to collect information. The data was analyzed by using appropriate statistical tests.
Results: In present study 49.02% were boys and 50.98% were girls. Majority of children belong to 13 years age group, and class-2 socio economic standard. About 58% of study population are from government school. Prevalence of obesity was 3.5% and it is more among girls and class-I socio economic status. There is significant association between obesity and excess calories intake, bakery and fatty food consumption, lack of physical activity, sedentary life style and family history.
Conclusion: It was concluded that main modifiable risk factors of obesity among school going children were junk food and sedentary life style
Models Predicting Effects of Missense Mutations in Oncogenesis
No full textThe recent avalanche in high-throughput genotyping, next generation sequencing technologies and re-sequencing of cancer genomes has revolutionized the field of cancer genomics. It has generated a humungous amount of mutational data and changed the way the cancer is being studied. Identification and characterization of these mutations and their mutational effect has become one of the major goals of cancer research. We present here a computational geometry approach based on the application of Delaunay tessellation derived four-body statistical potential function where the potentials are directly derived from the high-resolution protein x-ray crystallographic structures utilizing their atomic coordinates. Proteins and their mutants are characterized by potential topological scores and profiles, which measure the relative change in the overall sequence-structure compatibility. Residual scores and profiles are generated which quantify environmental perturbations from wild-type amino acids at every mutational position. We also present here an integrated database of human cancer missense mutations linked to their 3D structures, which has been created with the whole motivation of building a one stop shop of human missense mutations data sets huge and versatile enough to be used for training and testing of machine learning methodologies. With protein data from this database, we illustrate the use of potential topological cores and residual profiles in the prediction of mutational effects on protein structure and function and generating predictive models using machine-learning algorithms. We successfully apply supervised learning to training sets of protein mutants and generate models, which make statistically meaningful predictions of effects of missense mutations on cancer proteins.This work was embargoed by the author and will not be available until May 2015
Fractal Loaded, Novel, and Compact Two- and Eight-Element High Diversity MIMO Antenna for 5G Sub-6 GHz (N77/N78 and N79) and WLAN Applications, Verified with TCM Analysis
No full textA novel compact fractal loaded two- and eight-element multiple input multiple output (MIMO) with strong diversity is designed for 5G Sub 6 GHz and WLAN applications. The suggested antenna is designed and manufactured on inexpensive FR4 dielectric material with small size of 72 mm × 72 mm × 1.6 mm (0.792λ × 0.792λ × 0.0176λ, where λ is calculated at a lower operating frequency). The proposed layout features a partially grounded, protruding T-shaped stub on the underside of the substrate and a set of fractally loaded circular patch antenna elements on the top. Four triangular slots on the substrate and a T-shaped stub on the ground are employed to produce good isolation over the intended bands. The proposed antenna has a frequency range of (3.3–6.0) GHz, making it compatible with the 5G sub-6 GHz bands and the WLAN band thanks to its high isolation of above 15 dB and good impedance matching characteristics. Good agreement is observed between the antenna results and the theory of characteristic mode analysis approach. The designed antenna is well suited for 5G sub-6 GHz and WLAN communication applications due to its low ECC (0.005), total active reflection coefficient (TARC) (−10 dB), mean effective gain (MEG) (−3 dB), and diversity gain (DG) (−10 dB), channel capacity losses (CCL) (0.05), peak gain (>2.5 dBi), radiation efficiency (>95%), and stable boresight radiation patterns
Design and Analysis of Modified U-Shaped Four Element MIMO Antenna for Dual-Band 5G Millimeter Wave Applications
No full textA novel compact-slotted four element multiple input multiple output (MIMO) planar monopole antenna is proposed for 5G mmWave N257/N258 and N262 band applications. The antenna, with dimensions of 12 mm × 11.6 mm × 0.508 mm (1.036λo ×1.001λo×0.043λo where λo is computed at lowest cutoff frequency), is fabricated on a Rogers RT/duroid 5880 (tm) substrate with a relative permittivity of 2.2 and a dielectric loss tangent of 0.0009. The suggested antenna consists of four U-shaped radiating elements (patches) on top of the dielectric material and a slotted ground on the bottom. The radiating elements are fed by a 50-ohm microstrip line feed. To improve the impedance performance of the MIMO antenna, a rectangular strip of 1.3 mm × 0.2 mm and a couple of rectangular slots are added to each radiating element. The first operating band at 27.1 GHz, ranging from 25.9 GHz to 27.8 GHz, is achieved by using slotted U-shaped radiating elements. The second operating band at 48.7 GHz, ranging from 47.1 GHz to 49.9 GHz, is obtained by etching hexagonal slots on the ground. The antenna design achieves an isolation of >27 dB through the orthogonal positioning of radiating elements and slots on the ground. The designed antenna operates at 27 GHz (N257/N258) and 48.7 GHz (N262) bands, exhibiting stable radiation patterns, a peak gain of >5.95 dBi, radiation efficiency of >90%, an envelope correlation coefficient of −6, a total active reflection coefficient of ≤−10 dB, channel capacity losses of <0.03 bits/s/Hz, and a mean effective gain of ≤−3 dB. The simulated and measured results of the antenna show good agreement, making it well-suited for 5G mmWave communication applications
