One step growth of GaN/SiO2 core/shell nanowire in vapor-liquid-solid route by chemical vapor deposition technique
GaN/SiO2 core/shell nanowires are grown by cobalt phthalocyanine catalyst
assisted vapor-liquid-solid route, in which Si wafer coated with a mixture of
gallium and indium is used as the source for Ga and Si and ammonia is used as
the precursor for nitrogen and hydrogen. Gallium in the presence of indium and
hydrogen, which results from the dissociation of ammonia, forms Si-Ga-In alloy
at the growth temperature around 910 degree Celsius. This alloy acts as the
source of Si, Ga and In. A detailed study using a variety of characterization
tools reveals that these wires, which are several tens of micron long, has a
diameter distribution of the core ranging from 20 to 50 nm, while the thickness
of the amorphous SiO2 shell layer is about 10 nm. These wires grow along
direction. It has also been observed that the average width of these wires
decreases, while their density increases as the gallium proportion in the Ga-In
mixture is increased.Comment: 14 pages, 4 figure
Effect of final state interactions on neutrino energy reconstruction at DUNE
We quantitatively study the percentage of fake events present in CCQE and
CCRes interactions and the impact of final state interactions on the neutrino
oscillation parameters at Dune. Resonance interaction will be the most dominant
interaction in the oscillation sensitive region of DUNE. The effect of
final-state interactions for DUNE oscillation physics is analysed in an ideal
and realistic detector scenario. The -disappearance Oscillation
channel is studied using LAr detector. We find that nuclear effects and
detector thresholds plays an significant role in CCQE and CCRes interactions
and these nuclear effects induces a significant bias in the determination of
atmospheric oscillation parameters. The impression of nuclear effects on the
determination of is quantified in this work.Comment: 8 pages, 9 figure

Study of pattern of congenital anomalies at tertiary center in Maharashtra, India
Background: To highlight common pattern of congenital malformation seen at hospital population of tertiary care center in Maharashtra.Methods: The study was a descriptive prospective study and conducted in the department of obstetrics and gynaecology of government medical college Latur, Maharashtra for a period of six months. Study includes all womens coming for 2nd trimester MTP due to congenital anomalies in foetus and women’s admitted in labour having anomalous foetus. Details of maternal age, parity, type of anomaly present and sex of fetus were noted.Results: Total babies born in the study period were 3482 (including the second trimester abortions). Total babies with congenital abnormality were 75, making the prevalence 2.15%. 10 cases (13.33) had multiple anomalies involving more than one system. The predominant system involved was central nervous system 40 (53.33%) followed by gastrointestinal system 15 (20%). In this study male babies affected more than females.Conclusions: Prevalence of the congenital anomalies will be definitely higher at tertiary care center and to know prevalence in community, more community based studies are required. Increased awareness about preventable risk factors may help in reducing the incidence of congenital anomalies
In silico analysis for the presence of HARDY an Arabidopsis drought tolerance DNA binding transcription factor product in chromosome 6 of Sorghum bicolor genome
Expression of the Arabidopsis HARDY (hrd) DNA binding transcription factor (555 bp present on chromosome 2) has been shown to increase WUE in rice by Karaba et al 2007 (PNAS, 104:15270–15275). We conducted a detail analysis of the complete sorghum genome for the similarity/presence of either DNA, mRNA or protein product of the Arabidopsis HARDY (hrd) DNA binding transcription factor (555 bp present on chromosome 2). Chromosome 6 showed a sequence match of 61.5 percent positive between 61 and 255 mRNA residues of the query region. Further confirmation was obtained by TBLASTN which showed that chromosome 6 of the sorghum genome has a region between 54948120 and 54948668 which has 80 amino acid similarities out of the 185 residues. A homology model was constructed and verified using Anolea, Gromos and Verify3D. Scanning the motif for possible activation sites revealed that there was a protein kinase C phosphorylation site between 15th and 20th residue. The study indicates the possibility of the presence of a DNA binding transcription factor in chromosome 6 of Sorghum bicolor with 60 percent similarity to that of Arabidopsis hrd DNA binding transcription factor
