Nonsmooth semi-Infinite Minmax Programming Involving Generalized(Φ, ρ)-Invexity

引用

Journal of systems science & Complexity 2015年第4期28卷 857-875页

作者： UPADHYAY b b MIsHRA s k Department of basic sciences & Humanities National Institute of Technology

This paper introduces some new generalizations of the concept of （~, p）-invexity for non- differentiable locally Lipschitz functions using the tools of Clarke subdifferential. These functions are used to derive the necessary and sufficient optimality conditions for a class of nonsmooth semi-infinite minmax programming problems, where set of restrictions are indexed in a compact set. Utilizing the sufficient optimality conditions, the authors formulate three types of dual models and establish weak and strong duality results. The results of the paper extend and unify naturally some earlier results from the literature.

Journal of Zhejiang University-science b(biomedicine & biotechnology) 2007年第9期8卷 638-646页

作者： bALACHANDAR V. LAksHMAN kUMAR b. sAsIkALA k. MANIkANTAN P. sangeetha R. MOHANA DEVI s. Division of Human Genetics Department of Zoology Bharathiar University Coimbatore-641046 Tamilnadu India

The aim of the present investigation was to study the major chromosomal aberrations （CA） like deletion, translocation, inversion and mosaic in prostate cancer patients of Tamilnadu, southern India. Totally 45 blood samples were collected from various hospitals in Tamilnadu, southern India. Equal numbers of normal healthy subjects were chosen after signing a consent form. Volunteers provided blood samples （5 ml） to establish leukocyte cultures. Cytogenetic studies were performed by using Giemsaanding technique and finally the results were ensured by spectral karyotyping （skY） technique. In the present investigation, major CA like deletion, translocation, inversion and mosaic were identifed in experimental subjects. Results showed frequent CA in chromosomes 1, 3, 5, 6, 7, 9, 13, 16, 18 and X. In comparison with experimental subjects, the control subjects exhibited very low levels of major CA （P〈0.05）. In the present study, the high frequency of centromeric rearrangements indicates a potential role for mitotic irregularities associated with the centromere in prostate cancer tumorigenesis. Identification of chromosome alterations may be helpful in understanding the molecular basis of the disease in better manner.

Upgradation of bauxite by molecular hydrogen and hydrogen plasma

International Journal of Minerals,Metallurgy and Materials 2016年第10期23卷 1141-1149页

作者： b.R.Parhi s.k.sahoo s.C.Mishra b.bhoi R.k.Paramguru b.k.satapathy Department of Metallurgical and Materials Engineering National Institute of Technology Rourkela 769008 Odisha India Institute of Minerals and Materials Technology Bhubaneswar 751013 Odisha India kalinga Institute of Industrial Technology Bhubaneswar 751024 Odisha India National Aluminium Company Ltd. Bhubaneswar 751013 Odisha India

An approach was developed to upgrade the bauxite ore by molecular hydrogen and hydrogen plasma. A gibbsite-type bauxite sample was obtained from National Aluminium Company（NALCO）, Odisha, India. The obtained sample was crushed and sieved（to 100 μm） prior to the chemical analysis and grain-size distribution study. The bauxite sample was calcined in the temperature range from 500 to 700°C for different time intervals to optimize the conditions for maximum moisture removal. This process was followed by the reduction of the calcined ore by molecular hydrogen and hydrogen plasma. Extraction of alumina from the reduced ore was carried out via acid leaching in chloride media for 2 h at 60°C. X-ray diffraction, scanning electron microscopy, thermogravimetry in conjunction with differential scanning calorimetry, and Fourier transform infrared spectroscopy were used to determine the physicochemical characteristics of the material before and after extraction. Alumina extracted from the reduced ore at the optimum calcination temperature of 700°C and the optimum calcination time of 4 h is found to be 90% pure.

study of a collisionless magnetized plasma sheath with nonextensively distributed species

引用

Plasma science and Technology 2023年第12期25卷 14-23页

A weakly magnetized sheath for a collisionless, electronegative plasma comprising positive ions,electrons, and negative ions is investigated numerically using the fluid approach. The electrons are considered to be non-Maxwellian in nature and are described by Tsalli's distribution. such electrons have a substantial effect on the sheath properties. The study also reveals that non-Maxwellian distribution is the most realistic description for negative ions in the presence of an oblique magnetic field. In addition to the negative ion temperature, the sheath potential is also affected by the nonextensive parameters. The present research finds application in the plasma processing and semiconductor industry as well as in space plasmas.
