Study of the giant dipole resonance around the magic number 28 Open
The present study unfolds the relative importance of N/Z, shell effects, and thermal fluctuations in shaping the temperature dependence of the isovector giant dipole resonance (IVGDR) width. To this end, we measured the γ-ray spectra from …
Analysis of Poverty Status among Female Headed Tribal Households: Role of Public Distribution System Open
Reports have highlighted that the number of female-headed households in India are rising, however it has also been reported that these households are poorer than their male headed counterparts. The present paper has tried to explore this n…

Pairing phase transition in an odd–even hot <sup>69</sup>Zn nucleus Open
The pairing phase transition in an odd–even hot-rotating 69 Zn nucleus has been investigated by using the reported nuclear level density (NLD) data, which were experimentally extracted from the γ -gated particle spectra. The experimental N…
Enhanced symmetry energy bears universality of the r-process Open
The abundance of about half of the stable nuclei heavier than iron via the rapid neutron capture process or $r$-process is intimately related to the competition between neutron capture and $β$-decay rates, which ultimately depends on the b…

Proton entropy excess and possible signature of pairing reentrance in hot nuclei Open
The entropy excess caused by one proton (proton entropy excess) has been extracted for several pairs of medium and heavy mass nuclei such as (237U and 238Np), (231Th and 232Pa), (211Po and 212At), (196Pt and 197Au), and (90Y and 91Zr) usin…
Universal origin of heavy elements Open
The abundance of heavy elements above iron through the rapid neutron capture process or r-process is intimately related to the competition between neutron capture and $\beta$ decay rates, which ultimately depends on the binding energy of a…
Effect of weather parameters on the seasonal incidence of rice leaf folder (Cnaphalocrosis medinalis, Gunee) Open
Study was undertaken to determine the effect of weather parameters on rice leaf folder during 2015-16 at Krishi Vigyan Kendra Jagatsinghpur, Odisha. The leaf folder infestation was monitored through light trap catches and the infestation p…
Search for the trend of COVID-19 infection following Farr’s law, IDEA model and power law Open
Following power law, Farr’s law and IDEA model, we analyze the data of COVID-19 pandemic for India up to 2 May, 2020 and for Germany, France, Italy, the USA, Singapore, China and Denmark up to 26 April, 2020. The cumulative total number of…
Search for trends of Covid-19 infection in India, China, Denmark, Brazil, France. Germany and the USA on the basis of power law scaling Open
The corona virus (SARS-CoV-2) or Covid-19 pandemic is growing alarmingly throughout the whole world. Using the power law scaling we analyze the data of different countries and three states of India up to 1st April, 2020 and explain in term…
Seed biopriming and biopesticides vis a vis <i>Bemisia tabaci</i> and <i>Aphis craccivora</i> incidence on mung bean Open
Mungbean Vigna radiata (L.) Wilzeck suffers from poor productivity due to infestation of wide array of insect pests among which the whitefly Bemisia tabaci (Genn.) and aphid Aphis craccivora (Koch) are important. The present study evaluate…
Effect of planting dates on incidence of rice leaf folder and its impact on grain yield in north eastern coastal plains of Odisha Open
The present study was conducted at Krishi Vigyan Kendra Jajpur, Odisha India, during Kharif 2015&16 with an objectives to study on the effect of planting dates on incidence of rice leaf folder Cnaphalocrocis medinalis G. and its impact on …
Supplementary Material for: Association of the STAT6 rs3024974 (C/T) Polymorphism with IgE-Mediated Food Sensitization among West Bengal Population in India Open
Introduction: Genetic polymorphisms associated with IgE-mediated food sensitization have been a robust area of research for decades. A genome-wide search for susceptible loci regulating the IgE response (atopy) identified the candidate gen…
