Challenges of Women Entrepreneurs in India and the Emerging Dimensions: A Study

Indian society today has witnessed a surge of women entrepreneurship. There arises a need to examine the challenges of women entrepreneurs in greater depth. This study attempts to understand these challenges as well as explore the dimensions that emerge from these challenges. The study is based on exploratory qualitative study of 20 women entrepreneurs in India. The narratives reveal six major themes:  Desire to create self- identity and derive satisfaction through entrepreneurship, doing what one loves to do, perceiving risk taking as an enjoyable experience, entrepreneurship as a medium to contribute to society, success speaks for itself and willing to learn, unlearn and relearn

Wideband filter using meta material at THz frequency

Wideband filtering application using ceramic meta material is reported in this work. Reflective properties of both SNG and DNG, glass and ceramic materials are presented. Simulation results for both structures predict the wide reflected band is found at Terahertz frequency pertaining to above structures. Also non linear variation of “width of the reflected band” is found with varying the thickness of meta material structure

Nonlinear mode coupling analysis in the Tevatron

Increased demand for higher luminosities from Fermilab proton-antiproton collider requires higher intensities and increased number of bunches. The performance of existing 6 x 6 and the proposed 36 x 36 collider is often limited by the non-linear effects arising from beam-beam interactions, in particular for high intensity beams. The tune shifts and spread from increased long range interactions combined with higher order multipoles complicates the frequency spectrum of the particle motions. TEAPOT simulation program is used to generate turn by turn data that could be used in the nonlinear mode spectrums analysis. Bispectral mode analysis is discussed

Fermilab Main Injector commissioning status

The Fermilab Main Injector construction project is nearing completion. The commissioning of the Main Injector began in late 1998. The status of the beam studies and fulfillment of the project commissioning milestones is presented

Simulation of beam-beam effects in tevatron

The Fermilab accelerator complex is in the middle of an upgrade plan Fermilab III. In the last phase of this upgrade the luminosity of the Tevatron will increase by at least one order of magnitude. In order to keep the number of interactions per crossing manageable for experiments, the number of bunches will be increased from 6 {times} 6 to 36 {times} 36 and finally to {approximately}100 {times} 100 bunches. The beam dynamics of the Tevatron has been studied from Beam-Beam effect point of view in a ``Strong-Weak`` representation with a single particle being tracked in presence of other beam. This paper describes the beam-beam effect in 6 {times} 6 operation of Tevatron

Fused-salt-liquid-metal corrosion of refractory alloys in the presence of hot cell impurities

The pyrochemical conditioning of spent nuclear fuel for the purpose of final disposal is currently being demonstrated at Argonne National Laboratory (ANL). One aspect of this program is to develop a lithium preprocessing stage for the Fuel Conditioning Facility (FCF). Furthermore, a pilot scale of this preprocessing stage is being designed by ANL-W to demonstrate the in situ hot cell capability of this process. In this pilot scale system, fused lithium chloride salt is saturated with molten lithium to form a powerful fluxing compound with a vigorous reducing agent. During this stage of the fuel conditioning, the reduction will take place at a nominal temperature of 650 C in an argon-cell atmosphere contaminated with up to 10,000 ppm nitrogen, 100 ppm oxygen and 100 ppm of moisture. The maximum local temperature was calculated to be 725 C on the inner shell of the reduction vessel during operation. One of the significant concerns of this project is the system`s corrosion response in the presence of irradiated commercial fuel as well as atmospheric impurities. The purpose of this work was to demonstrate the potential corrosivity of the salt matrix in a worse case environment as well as provide a boundary for allowable impurities in the system during operation

Hybrid Renewable Energy Systems: An Integrated Approach to Rural Electrification

In recent years, there has been a marked shift in focus towards sustainable and renewable energy solutions, particularly in the context of developing nations. This article explores the immense potential of hybrid renewable energy (RE) systems for ushering in a transformative change in electrifying remote and rural areas within these countries. The importance of such endeavours becomes paramount as a multitude of nations globally seek strategies to diminish carbon footprints. Renewable energy systems, combining sources such as solar, wind, hydro, and biomass, emerge as crucial assets in this drive, especially when considering regions that remain largely isolated from major electrical grids. The growing emphasis on research in this domain, coupled with favourable policies, signifies a promising trajectory for RE in developing nations. Such hybrid models, by capitalising on the diverse spectrum of renewable resources at hand, are on the brink of initiating a revolution in rural electrification strategies. This review accentuates the urgency and significance of rapidly integrating these avant-garde systems, setting the stage for a future that is not only environmentally conscious but also ensures broader and more equitable access to energy

Singular Scaling Functions in Clustering Phenomena

We study clustering in a stochastic system of particles sliding down a fluctuating surface in one and two dimensions. In steady state, the density-density correlation function is a scaling function of separation and system size.This scaling function is singular for small argument -- it exhibits a cusp singularity for particles with mutual exclusion, and a divergence for noninteracting particles. The steady state is characterized by giant fluctuations which do not damp down in the thermodynamic limit. The autocorrelation function is a singular scaling function of time and system size. The scaling properties are surprisingly similar to those for particles moving in a quenched disordered environment that results if the surface is frozen.Comment: 8 pages, 3 figures, Invited talk delivered at Statphys 23, Genova, July 200

Approximate solution of the Duffin-Kemmer-Petiau equation for a vector Yukawa potential with arbitrary total angular momenta

The usual approximation scheme is used to study the solution of the Duffin-Kemmer-Petiau (DKP) equation for a vector Yukawa potential in the framework of the parametric Nikiforov-Uvarov (NU) method. The approximate energy eigenvalue equation and the corresponding wave function spinor components are calculated for arbitrary total angular momentum in closed form. Further, the approximate energy equation and wave function spinor components are also given for case. A set of parameter values is used to obtain the numerical values for the energy states with various values of quantum levelsComment: 17 pages; Communications in Theoretical Physics (2012). arXiv admin note: substantial text overlap with arXiv:1205.0938, and with arXiv:quant-ph/0410159 by other author
