Determinants of Leukocyte Margination in Rectangular Microchannels
Abhishek Jain, Lance L. Munn
PLOS ONE , 2009, DOI: 10.1371/journal.pone.0007104
Abstract: Microfabrication of polydimethylsiloxane (PDMS) devices has provided a new set of tools for studying fluid dynamics of blood at the scale of real microvessels. However, we are only starting to understand the power and limitations of this technology. To determine the applicability of PDMS microchannels for blood flow analysis, we studied white blood cell (WBC) margination in channels of various geometries and blood compositions. We found that WBCs prefer to marginate downstream of sudden expansions, and that red blood cell (RBC) aggregation facilitates the process. In contrast to tubes, WBC margination was restricted to the sidewalls in our low aspect ratio, pseudo-2D rectangular channels and consequently, margination efficiencies of more than 95% were achieved in a variety of channel geometries. In these pseudo-2D channels blood rheology and cell integrity were preserved over a range of flow rates, with the upper range limited by the shear in the vertical direction. We conclude that, with certain limitations, rectangular PDMS microfluidic channels are useful tools for quantitative studies of blood rheology.
On solution of the integral equations for the potential problems of two circular-strips
C. Sampath,D. L. Jain
International Journal of Mathematics and Mathematical Sciences , 1988, DOI: 10.1155/s0161171288000912
Abstract: Solutions are given to some singular integral equations which arise in two-dimensional Dirichlet and Newmann boundary value problems of two equal infinite coaxial circular strips in various branches of potential theory. For illustration, these solutions are applied to solve some boundary value problems in electrostatics, hydrodynamics, and expressions for the physical quantities of interest are derived.
Study of Digital Learning and its implementation on Student Mobility in Engineering Education
Rita Jain,,B. L. Pal
International Journal of Innovative Technology and Exploring Engineering , 2012,
Abstract: The advent of information and communication technologies (ICT), learning has entered into an era of change unparalleled in this generation. The issue is, how theoretical knowledge can apply to real world problem? Academics worldwide have come to the conclusion that traditional learning methods must give way to Digital learning (D-learning). However, in order to change a paradigm, there must be a change in the way that people believe, think and act. A change to Digital learning in engineering education is a paradigm that has its associated challenges. Innovations are required so as to accomplish Digital learning in engineering education. Developing Digital learning tools that will take engineering education beyond traditional capabilities is a part of this challenge. In this paper, I have presented a review on design and development of virtual classroom environment using real-time streaming technology for live and online activity. Student can access the lecture even in presence of mobility for engineering education and exchange their views and ideas on education matter with teachers. This virtual classroom environment with digital learning education can transform the conventional paper education to the paper less education.
Multiple Features Subset Selection using Meta-Heuristic Function
L. S. Maurya,Susheel Jain
International Journal of Computer Technology and Applications , 2011,
Abstract: This paper is being presented on Multiple Features Subset Selection Using Meta-heuristic Function. Classification problems require selection of a subset of attributes or features from a much larger dataset to represent the patterns to be classified. Many excellent multiple feature selection method such as Hill Climbing (HC), Simulated Annealing (SA), Genetic Algorithms (GAs), Tabu Search (TS) has been prevalent amongst research community. However, these approaches still encounter when the multiple feature of dataset is available and it need to choose those attribute which is best amongst the available features. So, in this paper basically considering the issue of multiple features are analyzed as well as implemented and tested on different dataset. The experiment is being conducted abalone dataset. It may conclude that the algorithm shows highest accuracy amongst all other method which is being used in this paper, Therefore we are focusing on the classification of multiple features
Implications of the Present Bound on the Width of the Theta(1540)
R. L. Jaffe,Ambar Jain
Physics , 2004, DOI: 10.1103/PhysRevD.71.034012
Abstract: The recently reported Theta(1540) exotic baryon seems to be very narrow: Gamma(Theta)< 1 MeV according to some analyses. Using methods of low energy scattering theory, we develop expectations for the width of the Theta, an elastic resonance in KN scattering in a theory where the characteristic range of interactions is ~1 Fermi. If the Theta is a potential scattering resonance, generated by the forces in the KN channel, its width is hard to account for unless the KN-channel orbital angular momentum, l, is two or greater. If the Theta is a CDD pole, its coupling to the scattering channel is at least an order of magnitude less than the coupling of the Lambda(1520) unless l is two or greater. Either way, if the Theta proves to be in the KN s- or p-wave, new physics must be responsible for its narrow width.
Mragyati : A System for Keyword-based Searching in Databases
N. L. Sarda,Ankur Jain
Computer Science , 2001,
Abstract: The web, through many search engine sites, has popularized the keyword-based search paradigm, where a user can specify a string of keywords and expect to retrieve relevant documents, possibly ranked by their relevance to the query. Since a lot of information is stored in databases (and not as HTML documents), it is important to provide a similar search paradigm for databases, where users can query a database without knowing the database schema and database query languages such as SQL. In this paper, we propose such a database search system, which accepts a free-form query as a collection of keywords, translates it into queries on the database using the database metadata, and presents query results in a well-structured and browsable form. Th eysytem maps keywords onto the database schema and uses inter-relationships (i.e., data semantics) among the referred tables to generate meaningful query results. We also describe our prototype for database search, called Mragyati. Th eapproach proposed here is scalable, as it does not build an in-memory graph of the entire database for searching for relationships among the objects selected by the user's query.
Anaerobic Membrane Bioreactor as Highly Efficient and Reliable Technology for Wastewater Treatment—A Review  [PDF]
Meenu Jain
Advances in Chemical Engineering and Science (ACES) , 2018, DOI: 10.4236/aces.2018.82006
Abstract:
In this review paper, Anaerobic Membrane Bioreactor (AnMBR) is considering as highly efficient and reliable technology for organic material removal from wastewater with no additional energy requirement for aeration. AnMBR is a combination of conventional anaerobic technology and modern membrane system. AnMBR is cost effective alternative technology with pros of anaerobic microbial activity because Methogenic microorganism can convert organic pollutant load of wastewater into renewable energy in the form of methane rich biogas, this conversion is mainly done by transformation of organic matter into energy by high chemical oxygen demand (COD), total suspended solid (TSS) and pathogens removal. Methane rich biogas can be used as a storable source of supplemental energy for the production of heat or power thus AnMBR technology provides improved effluent quality, reliability, and efficiency over the other traditional technologies. This review paper is included the overview of AnMBR, the advantages over other wastewater treatment technology, operational constraints and the concerned factors that has affected the performances of implemented systems, applications of AnMBR for various types of wastewaters, research and development summary and future perspective for further research.
Interior and exterior solutions for boundary value problems in composite elastic and viscous media
D. L. Jain,R. P. Kanwal
International Journal of Mathematics and Mathematical Sciences , 1985, DOI: 10.1155/s0161171285000242
Abstract: We present the solutions for the boundary value problems of elasticity when a homogeneous and isotropic solid of an arbitrary shape is embedded in an infinite homogeneous isotropic medium of different properties. The solutions are obtained inside both the guest and host media by an integral equation technique. The boundaries considered are an oblong, a triaxial ellipsoid and an elliptic cyclinder of a finite height and their limiting configurations in two and three dimensions. The exact interior and exterior solutions for an ellipsoidal inclusion and its limiting configurations are presented when the infinite host medium is subjected to a uniform strain. In the case of an oblong or an elliptic cylinder of finite height the solutions are approximate. Next, we present the formula for the energy stored in the infinite host medium due to the presence of an arbitrary symmetrical void in it. This formula is evaluated for the special case of a spherical void. Finally, we analyse the change of shape of a viscous incompressible ellipsoidal region embedded in a slowly deforming fluid of a different viscosity. Two interesting limiting cases are discussed in detail.
PEG-embedded KBr3: A recyclable catalyst for multicomponent coupling reaction for the efficient synthesis of functionalized piperidines
Sanny Verma,Suman L. Jain,Bir Sain
Beilstein Journal of Organic Chemistry , 2011, DOI: 10.3762/bjoc.7.157
Abstract: PEG-embedded potassium tribromide ([K+PEG]Br3 ) was found to be an efficient and recyclable catalyst for the synthesis of functionalized piperidines in high yields in a one step, three component coupling between aldehyde, amine and β-keto ester. At the end of the reaction the [K+PEG]Br3 was readily regenerated from the reaction mixture by treating the residue containing [K+PEG]Br with molecular bromine.
