Major and trace elements, including rare earth elements (REEs) geochemistry of bed sediments from the lower reaches of Krishna river suggest their origin mainly from weathering of Deccan basalts and Precambrian rocks of the southern India. The elemental compositions indicate evidence of sedimentary sorting during weathering, transportation and deposition. Highly depleted Na2O and high values of Chemical Index of Alteration (CIA) are suggestive of moderate to strong chemical weathering environment in lower reaches of Krishna river. Major, trace and REE concentrations of bulk sediments suggest marginal variations in relative contribution from mafic and felsic minerals. The bed sediments contain significantly low concentrations of trace elements like Ba, Sr, La, Ce and Nd and moderately low concentrations of V, Zr, Rb, Zn, Ni and Cr relative to upper continental crust (UCC) composition. Most of the other trace elements and REEs are almost similar to UCC indicating their origin from weathering of mixed rock types in catchment areas of Krishna river. Strong relationships of ΣREEs with Ti and Zr in bed sediments suggest that REEs are mainly controlled by heavy minerals such as titanite and zircon. A marked increase in REEs in clay fractions of sediments indicates their adsorption and/or substitution on clay lattice.

Vegetation carbon sequestration and regeneration are the two major parameters of forest research. In this study, we analyzed the vegetation carbon stock and regeneration of community-managed pine plantation of Kathmandu, central Nepal. Vegetation data were collected from 40 circular plots of 10 m radius (for the tree) and 1m radius (for seedling) applying a stratified random sampling and nested quadrat method. The carbon stock was estimated by Chave allometric model and estimated carbon stock was converted into CO2 equivalents. Density-diameter (d-d) curve was also prepared to check the regeneration status and stability of the plantation. A d-d curve indicates the good regeneration status of the forest with a stable population in each size class. Diversity of trees was very low, only two tree species Pinus roxburghii and Eucalyptus citriodora occurred in the sample plots. Pine was the dominant tree in terms of density, basal area, biomass, carbon stock and CO2 stock than the eucalyptus . The basal area, carbon stock and CO2 stock of forest was 33±1.0 m2 ha-1, 108±5.0 Mg ha-1 and 394±18 Mg ha-1, respectively. Seedling and tree density of the plantation was 4,965 ha-1 and 339 ha-1 respectively. The forest carbon stock showed a positive relationship with biomass, tree diameter, height and basal area but no relationship with tree density. Canopy cover and tree diameter have a negative effect on seedling density and regeneration. In conclusion, the community forest has a stable population in each size class, sequestering a significant amount of carbon and CO2 emitted from densely populated Kathmandu metro city as the forest biomass hence have a potentiality to mitigate the global climate change.

<P><B>Abstract</B></P> <P>The Sr<SUB>3</SUB>SiO<SUB>5</SUB>: Ce<SUP>3+</SUP>/Dy<SUP>3+</SUP> phosphors were prepared via a citrate assisted sol-gel method. The prepared samples were characterized by X-ray diffraction pattern, scanning electron microscopy, Fourier transform infrared spectroscopy and fluorescence spectroscopy. When excited with near-ultraviolet (NUV) (360nm) irradiation, the photoluminescence emission spectra showed a broad band blue emission of Ce<SUP>3+</SUP> ions combined with the sharp emission peaks of Dy<SUP>3+</SUP> ions. Energy transfer occurred between the Ce<SUP>3+</SUP> and Dy<SUP>3+</SUP> ions and it increased with the increase of Dy<SUP>3+</SUP> ion concentration. The luminescence properties of the prepared phosphor materials could be adjusted by changing the concentration ratio of the Ce<SUP>3+</SUP> and Dy<SUP>3+</SUP> ions. The prepared phosphor materials also exhibited good thermal stability.</P>

ON FUZZY k−IDEALS, k−FUZZY IDEALS AND FUZZY 2−PRIME IDEALS IN Γ−SEMIRINGS
Murali Krishna Rao, M.,Venkateswarlu, B. The Korean Society for Computational and Applied M 2016 Journal of applied mathematics & informatics Vol.34 No.5
The notion of Γ-semiring was introduced by M. Murali Krishna Rao [8] as a generalization of Γ-ring as well as of semiring. In this paper fuzzy k-ideals, k-fuzzy ideals and fuzzy-2-prime ideals in Γ-semirings have been introduced and study the properties related to them. Let μ be a fuzzy k-ideal of Γ-semiring M with |Im(μ)| = 2 and μ(0) = 1. Then we establish that M<sub>μ</sub> is a 2-prime ideal of Γ-semiring M if and only if μ is a fuzzy prime ideal of Γ-semiring M.

OBJECTIVES: To address and elucidate the impact of pharmacist-led home medicines review (HMR) services on identifying drug-related problems (DRPs) among the elderly population in home care settings. METHODS: A comprehensive systematic search was performed using electronic scientific databases such as PubMed, Scopus, Embase, and Web of Science for studies published between January 1, 2008 and December 31, 2018, pertaining to HMR services by pharmacists for identifying DRPs. RESULTS: In total, 4,292 studies were retrieved from the searches, of which 24 were excluded as duplicates. Titles and abstracts were screened for the remaining 4,268 studies, of which 4,239 were excluded due to the extraneous nature of the titles and/or abstracts. Subsequently, 29 full-text articles were assessed, and 19 were removed for lacking the outcome of interest and/or not satisfying the study’s inclusion criteria. Finally, 10 studies were included in the review; however, publication bias was not assessed, which is a limitation of this study. In all studies, pharmacists identified a highly significant amount of DRPs through HMR services. The most common types of DRPs were potential drug-drug interactions, serious adverse drug reactions, need for an additional drug, inappropriate medication use, non-adherence, untreated indications, excessive doses, and usage of expired medications. CONCLUSIONS: HMR is a novel extended role played by pharmacists. The efficiency of such programs in identifying and resolving DRPs could minimize patients’ health-related costs and burden, thereby enhancing the quality of life and well-being among the elderly.

Efficient Exonic Regions Prediction in DNA Sequence Using Fast Converged Adaptive Filter
Y. Murali Krishna,K. Murali Krishna,Ch. Amaranatha Sarma 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.5
Signal processing takes an important role in genomic with enormous data available in public domain. Generally digital filters are applied to predict the protein and genes, but it needs to be redesigned when the characteristic frequency and periodic behavior is changed. In this paper proposed the novel adaptive algorithm which can identify the genes and proteins effectively from unified framework. First using the electron ion potential method the symbolic DNA sequences are converted in to digital signal. Secondly the filtering scheme for genomic signal processing with periodic behavior in biological sequence is introduced, which can predict and analyze the biological region that are interested in. finally the proposed adaptive filtering method is applied to recognize the exons of protein coding regions according to periodic-3 property. The exons prediction curves are obtained with Discrete Fourier Transform (DFT), Least mean square (LMS), and proposed Fast Recursive least Mean Square (F-RLS) algorithms. It is shown that proposed method shows efficiency in convergence of identification and precise prediction of exons regions compared to existed methods.

The contagiousness of coronavirus disease 2019 (COVID-19) led to the imposition of historical lockdowns in various countries, the shutdown of industries, and the start of a new era of leading, learning, and working from home. No scientific mind could have made accurate projections of the tremendous impact that COVID-19 would have on nations, communities, and the global-wide economy. Meanwhile, millions of workers have lost their jobs, while healthcare workers are overwhelmed and are reaching a state of mental and physical exhaustion. With the uncontrollable spread of the disease, researchers have been tirelessly working to identify factors correlated with COVID-19 morbidity and mortality. In this regard, race, ethnicity, industry, and occupation have been found to be predominant factors of interest. However, unfortunately, the unavailability of reliable data on individuals’ race, ethnicity, occupational, and employment details has been a difficult reality. Since race, ethnicity, and employment are essential social determinants of health and could serve as potential risk factors for COVID-19, collecting such information may offer important context for prioritising vulnerable groups. Thus, this perspective aims to highlight the importance and need for collecting race, ethnicity, and occupation-related data to track and treat the racial/ethnic groups that have been most strongly affected by the COVID-19 pandemic. Collecting such data will provide valuable insights and help public health officials recognise workplace-related outbreaks and evaluate the odds of various ethnic groups and professions contracting COVID-19.

On fuzzy $k-$ideals, $k-$fuzzy ideals and fuzzy $2-$prime ideals in $\Gamma -$semirings
M. Murali Krishna Rao,B. Venkateswarlu 한국전산응용수학회 2016 Journal of applied mathematics & informatics Vol.34 No.5
The notion of $\Gamma -$semiring was introduced by M. Murali Krishna Rao \cite{8} as a generalization of $\Gamma -$ring as well as of semiring. In this paper fuzzy $k-$ideals, $k-$fuzzy ideals and fuzzy-$2-$prime ideals in $\Gamma -$semirings have been introduced and study the properties related to them. Let $\mu$ be a fuzzy $k-$ideal of $\Gamma -$semiring $M$ with $| Im(\mu)| =2$ and $\mu(0)=1.$ Then we establish that $M_{\mu}$ is a $2-$prime ideal of $\Gamma -$semiring $M$ if and only if $\mu$ is a fuzzy prime ideal of $\Gamma -$semiring $M.$
