Investigating the radial flow like effects using identified triggered correlation in pp collisions at = 7 TeV
An inclusive baryon to meson enhancement with increase in multiplicity has
been observed in pp collisions at = 7 TeV. Such a striking feature of
the data can be explained by approaches based on hydrodynamics and multi-parton
interactions (MPI) coupled with color reconnection (CR) mechanism. In this
paper, we investigate the multiplicity evolution of the charged particle yields
associated with pions and protons selected from the intermediate region
where the inclusive baryon to meson enhancement has been observed. The study
has been peformed using EPOS 3 (hydrodynamics) and PYTHIA 8 (MPI with CR) event
generators in pp collisions at 7 TeV. We find that the response of the
individual pion and proton triggered correlation towards these two mechanisms
is different and can be used to disentangle the effect of one from the other.
The current study can, therefore, provide important insights on the origin of
radial flow like effects in high multiplicity pp collisions at the LHC
energies.Comment: 5 pages, 6 figure
Temperature dependence of the band gap shrinkage due to electron-phonon interaction in undoped n-type GaN
The photoluminescence spectra of band-edge transitions in GaN is studied as a
function of temperature. The parameters that describe the temperature
dependence red-shift of the band-edge transition energy and the broadening of
emission line are evaluated using different models. We find that the
semi-empirical relation based on phonon-dispersion related spectral function
leads to excellent fit to the experimental data. The exciton-phonon coupling
constants are determined from the analysis of linewidth broadening

Study on the effect of toxicity under highly arsenic prone zone in Nadia district of West Bengal in India
The present study was carried out on the basis of status of arsenic in soil, drinking water and plants, blood, urine and faeces of animals at arsenic prone zone. Within the ambit with the environment, the examination of animals was taken into consideration. They were screened and categorised on the degree of As toxicity. For field works animals were randomly selected from arsenic prone zone. The external manifestation indicated a complex syndrome and characteristic signs such as increased heart rate and respiratory rate, red urine, congested mucous membrane, anorexia, absence of ruminal motility, diarrhoea with blood, polyuria and unusual weight loss. The haematobiochemical changes such as low Hb level, decreased level of TEC, TLC and increased level ALT, AST, BUN and creatinine. Increased level of arsenic in urine, blood and faeces than the value of control animals could be the confirmatory indication of arsenic toxicity
Evaluation of rapeseed-mustard cultivars under late sown condition in coastal ecosystem of West Bengal
In our present report, we evaluated seven rapeseed mustard cultivars at coastal saline zone of West Bengal, India under rice-mustard sequence in a triplicated randomized block design for 14 traits to study their performance under late sown (2nd December) condition. The cultivars were sown at 30 cm × 10 cm spacing during winter of 2013?14 and 2014?15. The soil was clay in texture and had the following key properties for the 0?30 cm layer: pH 5.84, electrical conductivity (EC) 1.55 dS/m, available nitrogen (N) 155.24 kg/ha, available phosphorus (P) 105.76 kg/ha, available potassium (K) 365.86 kg/ha and available B 2.63 kg/ha. Among the seven cultivars, Kranti produced significantly (p?0.05) higher seed yield (1.33 t/ha) closely followed by the hybrids PAC-409 (1.23 t/ha) and Pusa Bold (1.21 t/ha). Seed yield showed significant (p?0.05) positive correlation with all the independent variables (plant height, R2=0.88; dry matter, R2=0.42; days to 50 % flowering, R2=0.27; number of siliqua/plant, R2=0.38; seeds/siliqua, R2=0.48; except number of fertile plants/m2, R2=-0.06; number of secondary branches/plant, R2=-0.97 and length of siliqua, R2=-0.07). However, number of secondary branches/plant had significant (p?0.05) and negative correlation with seed yield of mustard (R2=-0.97). Plant height revealed the highest degree of correlation (R2=0.88) with seed yield followed by siliqua per main branch (R2=0.77), days to harvest (R2=0.75) and 1000-seed weight (R2=0.52). The results indicated that selection of suitable rapeseed mustard cultivars based on these traits would be more effective in improving seed yield in mustard
