his investigation was carried out to reveal the impact of solar radiation on wind flow structure and pollutant dispersion in an urban street canyon of aspect ratio of one using the computational fluid dynamic (cfd) technique. the simulation results (velocity and concentration data) show that heating from building wall surfaces and ground lead to strong buoyancy forces as the air is heated by th...

OBJECTIVE To determine the early effects of Coronary Artery Bypass Grafting (CABG) on regional left ventricular wall motion abnormality in patients undergoing surgery for proven Coronary Artery Disease (CAD). DESIGN Quasi-experimental study. PLACE AND DURATION OF STUDY Department of Cardiac Surgery, National Institute of Cardiovascular Diseases, Karachi. from October 2005 to April 2006. P...

This paper develops a simple growth model that embeds distorted factor markets and government intervention that achieves high economic growth, low consumption, and high investment simultaneously. All of these phenomena are consistent with Chinese macroeconomic data since the 1990s, implying the inefficiency of economic growth.

according to the iranian code of practice for seismic resistant design of buildings, soft storey phenomenon happens in a storey when the lateral stiffness of the storey is lower than 70% of the stiffness of the upper storey, or if it is lower than 80% of the average stiffness of the three upper stories. in the combined structural systems containing moment frames and shear walls, it is possible ...

The focus of this work is to investigate the adhesion characteristics a permanent magnet arrangement over ferromagnetic surfaces for wall climbing robot applications. changes in thickness affect robot, turn influences payload and alters operating conditions. effect varying on strength wall-climbing an area barely investigated being explored work. A two-dimensional model mechanism surface develo...

The resistive wall mode ~RWM! poses a threat to many plasma confinement devices. The continuous rotation of the wall relative to the plasma makes it appear perfectly conducting, because of the skin effect, but this is ineffective if the perturbation locks to the wall. This raises the question of whether a nonuniformly rotating wall is more effective. In this paper we discuss the effect of such ...

Semi-buried structures are most commonly used at first line of defense along the border between two countries. This demands investigation of their dynamic behaviour under blast loading. Herein, a semi-buried structure with foam sandwiched walls and buttresses to reduce the effect of blast is analysed. The effect of provision of different configurations of buttresses and foam core between two la...

Objective(s) The fractions of Candida albicans have been used as an immunomodulator. The present work assessed the effect of different fractions of C. albicans on nitric oxide (NO) production by mice peritoneal macrophages. Materials and Methods Cell wall and cytoplasmic fractions of C. albicans ATCC 10321 strain were extracted. Mice peritoneal macrophages were purified and cultured. Differen...
