In this paper, we have discussed a subclass T S(γ, α, µ, q, m)of univalent functions with negative coeffi cients related to pascal distribu-taries series in the unit disk U = { z ∈ C : | z | < 1 } . We obtain basic prop-erties like coeffi cient inequality, distortion and covering theorem, radii ofstarlikeness, convexity and close-to-convexity, extreme points, Hadamardproduct, and closure theorems for functions belonging to our class.

Evaluation of ISSR and RAPD Markers for the Detection of Genetic Diversity in Mulberry (Morus spp.)
Venkateswarlu, M.,Nath, B.Surendra,Saratchandra, B.,Urs, S.Raje Korean Society of Sericultural Science 2004 International Journal of Industrial Entomology Vol.9 No.2
The present study was carried out to evaluate the ISSR and RAPD markers for their efficiency as genetic marker systems to establish the relationships between 18 mulberry genotypes. A total of 36 from 56 (64%) RAPD primers and 12 from 48 (25%) ISSR primers produced reproducible amplification patterns. A high proportion of polymorphic bands ranging from 44 to 91% was observed respectively with RAPD and ISSR markers. The average Resolving Power (Rp) of ISSR primers was higher than RAPD primers. The ISSR primers, UBC 825, 868 and 873, and RAPD primers, UBC 712, 720 and 729, possessed the highest Rp values and could in each instance distinguish all the 18 genotypes. Similarity matrix values were estimated based on Jaccards coefficient, considering 109 polymorphic ISSR and 212 polymorphic RAPD bands and two dendrograms were constructed. The dendrograms obtained with ISSR and RAPD markers distinguished the eight exotic genotypes from the ten indigenous (Indian) genotypes. A significant correlation value (r=0.959; p=0.001) for the cophenetic matrix between the RAPD and ISSR matrices was observed. The results indicated that the ISSR and RAPD markers could assist in the differentiation of genotypes and permit the determination of genetic distances that might be exploited by mulberry breeders in improvement programs.

Performance, combustion and emission results of the diesel engine fueled with biodiesel blends with cetane improver as additive are presented in this paper. Cetane improver Ethyl Hexyl Nitrate (EHN) as 0.5% and 1% by volume is added as an additive to diesel-biodiesel blends. Experiments were conducted on a single cylinder, four stroke, and naturally aspirated, direct injection diesel engine with the said fuels using Exhaust Gas Recirculation (EGR) to analyze the performance, combustion and emissions. Experimental results reveal that both cylinder pressure and Heat Release Rate (HRR) decreased with increase in blend percentage and EGR as well. With increase in EHN percentage, CO and HC emissions decreased considerably while NOx decreased marginally. Smoke increases with increase in both EHN and EGR, however, at a particular EGR, blends with cetane improver present the better performance with improved emissions.
A new subclass of meromorphic functions associated with Bessel functions
Sujatha,B. Venkateswarlu,P. Thirupathi Reddy,S. Sridevi 한국전산응용수학회 2023 Journal of applied mathematics & informatics Vol.41 No.5
In this article, we are presenting and examining a subclass of Meromorphic univalent functions as stated by the Bessel function. We get disparities in terms of coefficients, properties of distortion, closure theorems, Hadamard product. Finally, for the class $ \Sigma^* (\wp,\ell,\hbar,\tau,c)$, we obtain integral transformations.
UNIQUENESS OF CERTAIN TYPES OF DIFFERENCE-DIFFERENTIAL POLYNOMIALS SHARING A SMALL FUNCTION
RAJESHWARI, S.,VENKATESWARLU, B.,KUMAR, S.H. NAVEEN The Korean Society for Computational and Applied M 2021 Journal of applied mathematics & informatics Vol.39 No.5
In this paper, we investigate the uniqueness problems of certain types of difference-differential polynomials of entire functions sharing a small function. The results of the paper improve and generalize the recent results due to Biswajit Saha [18].

This study aims to determine the optimal solution to transportation problems. We proposed a novel approach for tackling the initial basic feasible solution. This is a critical step toward achieving an optimal or near-optimal solution. The transportation issue is an issue of distributing goods from several sources to several destinations. The literature demonstrates many ways to improve IBFS. In this work, to solve the IBFS, we suggested a new method based on the statistical formula called cumulative distribution function (CDF) in exponential distribution, and inverse contra-harmonic mean (ICHM). The spreadsheet converts transportation cost values into exponential cost cell values. The stepping-stone method is used to identify an optimum solution. The results are compared with other existing methodologies, the suggested method incorporates balanced, and unbalanced, maximizing the profits, random values, and case studies which produce more effective outcomes.

In this paper, we introduce the notion of fuzzy ideal, fuzzy $k$-ideal and fuzzy $r$-ideal in $\Gamma$-incline. We study the properties of fuzzy ideals, fuzzy $k$-ideals and fuzzy $r$-ideals in $\Gamma$-incline.
