Cosmology using long gamma-ray bursts: statistical analysis of errors in calibrated data

Research in Astronomy and Astrophysics 2019年第2期19卷 143-150页

作者： Meghendra Singh Shashikant Gupta Amit sharma Satendra sharma Dr.A.P.J.Abdul Kalam Technical University G.D.Goenka University Amity University Haryana Yobe State University

We investigate direction dependence and non-Gaussian features in high-z cosmological data using ?_(χ~2) and ?_χ statistics and the Kolmogorov-Smirnov test. These techniques are applied on a set of calibrated long gamma-ray bursts(GRBs) and its combination with recent Type Ia supernovae data(Union2). Our statistical analysis shows a weak but consistent direction dependence in both the data *** analysis also indicates a non-Gaussian nature of errors in both data sets.

Chinese Physics C 2017年第8期41卷 101-107页

作者： Honey sharma Neha sharma H.M.Mittal Dr.B.R.Ambedkar National Institute of Technology Jalandhar144011India CT Institute of Engineering Management and Technology Jalandhar144020India

The systematics of kinematic moment of inertia J and dynamic moment of inertia J of superdeformed（SD） bands in A -130, 150, 190 mass regions have been studied. We have obtained the values of J^（1） and J^（2）for all the SD bands observed in the A-130, 150, 190 mass regions by using the experimental intraband E2 transition energies. The result of this work includes the variation of J with the product of valence proton and neutron numbers（NpNn）. The phenomenon of band mixing has been observed in the A -130, 150 mass regions and band crossing has been observed in the A-190 mass region. The systematics also includes the variation of J with the product of valence proton and neutron numbers（NpNn）. Evidence of staggering behaviour has been observed in all three A-130, 150 and 190 mass regions. We present for the first time the variation of J^（1）and J^（2）of SD bands in the A-130, 150, 190 mass regions with NpNn.

In vivo antianxiety and antidepressant activity of Murraya paniculata leaf extracts

引用

Journal of Integrative Medicine 2017年第4期15卷 320-325页

作者： Pragya sharma Sonali Batra Ashwani Kumar Anupam sharma University Institute of Pharmaceutical Sciences Panjab University

OBJECTIVE： Different parts of Murraya paniculata have been used traditionally for treating several ailments including mental disorders. The present study was designed to evaluate the antianxiety and antidepressant potential of M. paniculata leaves using elevated plus maze model and forced swim test, respectively. METHODS： Extracts of M. panicu/ata made with petroleum ether （60-80 ℃）, chloroform, ethanol and water were evaluated for antianxiety and antidepressant activity. The anxiolytic chloroform extract was subjected to column chromatography, yielding five fractions （F1-F5）. Fraction F5 （100 mg/kg）, which showed notable anxiolytic activity, was further chromatographed to get four subfractions （F5.1-F5.4）. Simultaneously, the ethano extract was partitioned with ethyl acetate to obtain ethyl acetate soluble fraction （EASF） and ethyl acetate insoluble fraction. Phytochemical screening of bioactive extracts/fractions and detection of mahanimbine in M paniculata leaf extract by thin-layer chromatography was also carried out. RESULTS： Fraction F5.3 （25 mg/kg） and EASF （20 mg/kg） showed significant anxiolytic and antidepressant activity, respectively. Thin-layer chromatography and phytochemical screening demonstrated the absence of mahanimbine in M. paniculata leaves. Coumarins were observed to be responsible for the anxiolytic activity. CONCLUSION： The results validate the traditional use of M. paniculata leaves in the treatment of menta disorders.

Study of various ground state decay mechanisms of Actinide nuclei

The special property of the actinide mass region is that nuclei belonging to this group are radioactive and undergo different ground state processes,such as alpha decay,cluster radioactivity(CR),heavy particle radioactivity(HPR),and spontaneous fission(SF).In this study,the probable radioactive decay modes of the heavy mass region(Z=89−102)are studied within the framework of the preformed cluster model(PCM).In the PCM,the radioactive decay modes are explored in terms of the preformation probability(P0)and penetration probability(P)at the turning point Ra,where the penetration of fragments is initiated[Ra=RT(touching state)+ΔR(neck length parameter)].First,the alpha decay half-lives are calculated for light and heavy nuclei,and Ra points are obtained by optimizing the neck length *** Ra points are further employed to fix the Q-value dependent turning point(Ra(Q)).Then,using the(Ra(Q))relation,the decay half-lives are computed,and the calculated results are compared with the available theoretical and experimental *** isotopical trend of P0 and P is studied with respect to the mass number of the parent and daughter nucleus,*** CR and HPR channels are also explored,and a comparison of calculated data is conducted with the available *** analysis of the fragmentation potential and preformation probability is carried out for alpha decay and *** mass distribution of the nuclei is studied as a function of fragment mass(A2)by considering the spherical and hot-compact deformation of the decaying ***,the most probable fission fragments are identified using the fragmentation structure,and the corresponding fission fragment total kinetic energy of the identified fragments is calculated and compared with available data,wherever applicable.
