CERTAIN RESULTS ON SUBMANIFOLDS OF GENERALIZED SASAKIAN SPACE-FORMS
( Sunil Kumar Yadav ),( Sudhakar K Chaubey ) 호남수학회 2020 호남수학학술지 Vol.42 No.1
The object of the present paper is to study certain geometrical properties of the submanifolds of generalized Sasakian space-forms. We deduce some results related to the invariant and anti-invariant slant submanifolds of the generalized Sasakian space-forms. Finally, we study the properties of the sectional curvature, totally geodesic and umbilical submanifolds of the generalized Sasakian space-forms. To prove the existence of almost semiinvariant and anti-invariant submanifolds, we provide the non-trivial examples.

A NOTE ON (k, μ)′ -ALMOST KENMOTSU MANIFOLDS
( Sunil Kumar Yadav ),( Yadab Chandra Mandal ),( Shyamal Kumar Hui ) 호남수학회 2021 호남수학학술지 Vol.43 No.4
The present paper deals with the study of generalized quasiconformal curvature tensor inside the setting of (k, μ)′ -almost Kenmotsu manifold with respect to η-Ricci soliton. Certain consequences of these curvature tensor on such manifold are likewise displayed. Finally, we illustrate some examples based on this study.

Background Orthopedic metallic screws even post healing causes ‘pinching eff ect’ and load infl ammation to the bone. In this work, the design and development of a novel metallic core and polymeric shell orthopedic screw is discussed along with optimization of manufacturing process. Methods A comparative 2D fi nite element study for pull-out test was conducted on HA, HB, HC, and HD standards of screws for approximately identical diameters to determine the type of threading for the proposed design of the novel orthopedic screw. The polymeric shell of the orthopedic screws was manufactured by injection molding process. The material used for manufacturing the polymeric shell was poly-l-lactic acid. Injection pressure, injection velocity, packing pressure and packing time of the injection molding process were optimized for the following output responses: maximum axial pull-out strength, and maximal bending strength of the screw. Results The r-squared and the adjusted r-squared value of the developed regression model for pull-out was found to be 96% and 92%, respectively. For the bending force, the developed regression model had a r-squared and adjusted r-squared value of 87% and 75%, respectively. The regression models were maximised to obtain the desired input parameters. The optimised parameters were validated experimentally at two local maxima for both pull-out and bending force. Signifi cance The developed screw is novel in design and a patent has been fi led under US patent offi ce with number US 2022/0000529 A1. The screws can be used by medical practitioners to avoid or minimise revision surgery and infl ammation.

On Applications of Weyl Fractional q-integral Operator to Generalized Basic Hypergeometric Functions
Yadav, Rajendra Kumar,Purohit, Sunil Dutt Department of Mathematics 2006 Kyungpook mathematical journal Vol.46 No.2
Applications of Weyl fractional $q$-integral operator to various generalized basic hypergeometric functions including the basic analogue of Fox's H-function have been investigated in the present paper. Certain interesting special cases have also been deduced.

DOES SOCIAL MEDIA PROMOTES NON-DECEPTIVE COUNTERFEITING? EMPIRICAL EVIDENCES FROM INDIA
Ritu Raj,Saurabh Verma,Sunil Kumar Yadav 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07
Social media has become popular in both business and research as many studies have explored the impact of this medium on the purchase behavior of consumers but surprisingly not in the domain of counterfeiting. Social media has become a significant part of today's lifestyle and it has created new channels for brand manufacturers and consumers to communicate. The present study tries to assess the impact of social media determinants on counterfeit purchase intention. The study explored three factors of social media namely social media platform, user-generated content, and social media word of mouth. Further, the study checks for the mediation effect of consumer attitude between social media determinants and purchase intention. The data for the present study were collected from three metropolitan cities of India namely Delhi, Kolkata, and Mumbai. The PLS-SEM was used on 406 respondents for further analysis and validation. The results revealed that there is a significant relationship between social media platforms, user-generated content, and purchase intention. However, an insignificant relationship was found between social media word of mouth and purchase intention. Further, the study suggested that attitude mediates the relationship between social media determinants and the purchase intention of consumers towards the purchase of counterfeit products in India.
