QUASI-PARA-SASAKIAN MANIFOLD ADMITTING ZAMKOVOY CONNECTION

The purpose of the present study is to deduce some curvature properties of quasi-para-Sasakian manifold equipped with respect to Zamkovoy connection. In the present article we have studied Locally $\phi$-symmetric quasi-para-Sasakian manifold, $\phi$-recurrent quasi-para-Sasakian manifold, Locally projective $\phi$-symmetric quasi-para-Sasakian manifold, $\phi$-projectively flat quasi-para-Sasakian manifold, pseudo-quasi-conformally flat quasi-para-Sasakian manifold,  $\phi$-pseudo-quasi-conformally flat quasi-para-Sasakian manifold with respect to Zamkovoy connection. Also we have shown that the quasi-para-Sasakian manifold with respect to Zamkovoy connection $\bar{\nabla}$ satisfying $\bar{\tilde{V}}(\xi, U).\bar{S}=0,$ where $\bar{\tilde{V}}$ and $\bar{S}$ are the pseudo-quasi-conformal curvature tensor and Ricci tensor with respect to Zamkovoy connection respectively

A report on freshwater tailless flea, Simocephalus vetulus from Haridwar, located in foothills of Shivalik Himalaya in Uttarakhand, India

The Cladocerans, commonly known as “Water fleas” form a primitive freshwater group of micro crustacean zooplankton of the freshwater ecosystem. They play an important role in the aquatic food chain and also contribute significantly to zooplankton dynamics and secondary productivity in freshwater ecosystems. The animals used in the present study were identified as Simocephalus vetulus with the help of identification keys described by various authors in the previous studies from other parts of India. In the present study, the occurrence of “freshwater tailless flea”, S. vetulus (Crustacea- cladocera) is reported for the first time from freshwater bodies in Haridwar, located in foothills of Shivalik Himalayan region in Uttarakhand. The presence of S. vetulus “tailless water flea” will be helpful as a lab model for the health status of aquatic bodies as well as environmental monitoring

Biomolecular interaction simulation of supramolecular topologies of organometallic assemblies of Bi(V) with antibiotic Tetracycline Amoxicillin drugs and their experimental activities evaluation

This is an accepted manuscript of an article published by IS Publications in Journal of Biomedical & Therapeutic Sciences on 30/09/2020, available online: http://www.pubs.iscience.in/journal/index.php/jbts/article/view/926/594 The accepted version of the publication may differ from the final published version.Antibiotic drugs i.e. tetracycline and amoxicillin, were used mixed ligands (ML), for designing, architecturing, tailoring and synthesis for synthesis of supramolecular topologies of organometallic assemblies of Bi(V), represented as OMCs‐Bi(V), having O5 set for bonding. Molecular models were proposed as a standard to judge specific interactions in topologies of molecules of ML and derived organometallic assemblies. In OMCs‐Bi(V), on chelation, polarity of Bi(V) get reduced to great extent due to overlap of ML orbital. As a result, delocalization of π‐electrons density clouds get spread over the surface of chelating ring and enhances penetration power of OMCs‐Bi(V) into lipid membranes. This influenced binding with enzyme sites in microorganisms. Some electron set for bonding groups present in ligands moieties display extensive biological activity that may be responsible for increase in hydrophobic character and liposolubility of supramolecular topologies of organometallic of assemblies; ultimately enhanced biological activity of OMCs‐Bi(V)

New genomic regions identified for resistance to spot blotch and terminal heat stress in an interspecific population of triticum aestivum and T. spelta

Wheat is one of the most widely grown and consumed food crops in the world. Spot blotch and terminal heat stress are the two significant constraints mainly in the Indo–Gangetic plains of South Asia. The study was undertaken using 185 recombinant lines (RILs) derived from the interspecific hybridization of ‘Triticum aestivum (HUW234) × T. spelta (H+26)’ to reveal genomic regions associated with tolerance to combined stress to spot blotch and terminal heat. Different physiological (NDVI, canopy temperature, leaf chlorophyll) and grain traits (TGW, grain size) were observed under stressed (spot blotch, terminal heat) and non-stressed environments. The mean maturity duration of RILs under combined stress was reduced by 12 days, whereas the normalized difference vegetation index (NDVI) was 46.03%. Similarly, the grain size was depleted under combined stress by 32.23% and thousand kernel weight (TKW) by 27.56% due to spot blotch and terminal heat stress, respectively. The genetic analysis using 6734 SNP markers identified 37 significant loci for the area under the disease progress curve (AUDPC) and NDVI. The genome-wide functional annotation of the SNP markers revealed gene functions such as plant chitinases, NB-ARC and NBS-LRR, and the peroxidase superfamily Cytochrome P450 have a positive role in the resistance through a hypersensitive response. Zinc finger domains, cysteine protease coding gene, F-box protein, ubiquitin, and associated proteins, play a substantial role in the combined stress of spot blotch and terminal heat in bread wheat, according to genomic domains ascribed to them. The study also highlights T. speltoides as a source of resistance to spot blotch and terminal heat tolerance

Constraints on the χ_(c1) versus χ_(c2) polarizations in proton-proton collisions at √s = 8 TeV

The polarizations of promptly produced χ_(c1) and χ_(c2) mesons are studied using data collected by the CMS experiment at the LHC, in proton-proton collisions at √s=8  TeV. The χ_c states are reconstructed via their radiative decays χ_c → J/ψγ, with the photons being measured through conversions to e⁺e⁻, which allows the two states to be well resolved. The polarizations are measured in the helicity frame, through the analysis of the χ_(c2) to χ_(c1) yield ratio as a function of the polar or azimuthal angle of the positive muon emitted in the J/ψ → μ⁺μ⁻ decay, in three bins of J/ψ transverse momentum. While no differences are seen between the two states in terms of azimuthal decay angle distributions, they are observed to have significantly different polar anisotropies. The measurement favors a scenario where at least one of the two states is strongly polarized along the helicity quantization axis, in agreement with nonrelativistic quantum chromodynamics predictions. This is the first measurement of significantly polarized quarkonia produced at high transverse momentum
