The problem of blood flow through a narrow catheterized artery with an axially nonsymmetrical stenosis has been investigated. Blood is represented by a two-phase macroscopic model, i.e., a suspension of erythrocytes (red cells) in plasma (Newtonian fluid). The coupled differential equations for both fluid (plasma) and particle (erythrocyte) phases have been solved and the expression for the flow characteristics, namely, the flow rate, the impedance (resistance to flow), the wall shear stress and the shear stress at the stenosis throat have been derived. It is found that the impedance increases with the catheter size, the hematocrit and the stenosis size (height and length) but decreases with the shape parameter. A significant increase in the magnitude of the impedance and the wall shear stress occurs even for a small increase in the catheter size. The flow resistance increases and the shear stress at the stenosis throat decreases with the increasing catheter size and assume an asymptotic value at about the catheter size half of the artery size. © 2009 Elsevier Ltd.

Utility of the several techniques of modern biotechnology, including various approaches towards genetic modification, have allowed the development of several genetically modified (GM) crops. A lot of progress has been made in the area of plant breeding and modification of certain plant traits based on a fuller and better understanding of the plant genome. It is important in the present status and for the future potential of biotechnology to crop modification and its relation to oils and fats industry be assessed in terms of actual realities rather than those of wishful expectation. From the last three decades, variety of techniques have been introduced and developed for in genetic modification of plants. Acceptance of GM crops has not been universal. The technology for modifying the plant genome to produce consumer desirable products is available and is evolving. Concern among individual government and national consumers are having major impacts on further applications of these crop varieties and their global trade. Source

This paper describes the model to evaluate and grade the Java programs, based on QMOOD (Quality Model for Object Oriented Design). QMOOD is the hierarchical model that defines relation between qualities attributes(like reusability, functionality, effectiveness, understand ability, extendibility, flexibility) and design properties with the help of equations. In this research we have developed the system based on QMOOD which is use to evaluate the quality of JAVA programs. In this we would try evaluate all quality attributes by finding the design metrics that is based on design property of object oriented design. Though QMOOD metrics are subjective in nature but still with the help of relationship between quality attributes and design property defined, we have calculated and aggregated these qualities attributes and evaluate the quality of program input We have tested the system with number of different programs that vary in their complexities and functionalities. © 2014 IEEE.

Assessment of Object Oriented Software Design Quality has been an important issue among researchers in Software Engineering discipline. In this paper, we propose an approach for determining the design quality of Object Oriented Software System. The approach makes use of a set of UML diagrams created during the design phase of the development process. Design metrics are fetched from the UML diagrams using a parser developed by us and design quality is assessed using a Hierarchical Model of Software Design Quality. To validate the design quality, we compute the product quality for the same software that corresponds to the UML design diagrams using available tools METRIC 1.3.4, JHAWK and Team In a Box. The objective is to establish a correspondence between design quality and product quality of Object Oriented Software. For this purpose, we have chosen priory known three software of Low, Medium and High quality. This is a work under progress, though; the substantial task has already been completed. © 2013 IEEE.

The manganese doped layered ceramic samples (Na1.9Li 0.1)Ti3O7 : XMn(0-01 ≤X≤0-1) have been prepared using high temperature solid state reaction. The room temperature electron paramagnetic resonance (EPR) investigations exhibit that at lower percentage of doping the substitution of manganese ions occur as Mn3+ at Ti4+ sites, whereas for higher percentage of doping Mn 2+ ions occupy the two different interlayer sodium/lithium sites. In both cases, the charge compensation mechanism should operate to maintain the overall charge neutrality of the lattice. The manganese doped derivatives of layered Na1.9Li0.1Ti3O7 (SLT) ceramics have been investigated through frequency dependence dielectric spectroscopy in this work. The results indicate that the dielectric losses in these ceramics are the collective contribution of electric conduction, dipole orientation and space charge polarization. Smeared peaks in temperature dependence of permittivity plots suggest diffuse nature of high temperature ferroelectric phase transition. The light manganese doping in SLT enhances the dielectric constant. However, manganese doping decreases dielectric loss due to inhibition of domain wall motion, enhances electron-hopping conduction, and impedes the interlayer ionic conduction as well. Manganese doping also gives rise to contraction of interlayer space. © Indian Academy of Sciences. Source
