ITE JOURNAL / JANUARY 2003 INTRODUCTION Approaches to combat urban traffic congestion span from demand management to physical expansion of road capacity. Attempts to shift a part of peak travel from car to high-quality public transit and to times when roads are relatively less crowded sometimes have been successful.1,2 Also, intelligent transportation systems (ITS) have the promise to optimize ...

In this paper, results are presented on asymmetric sloshing in partially filled circular cylinders subjected to horizontal, periodic forcing, as well as geyser formation and the subsequent axi-symmetric sloshing that is caused by a sudden change in Bond number. Asymmetric sloshing is controlled by three parameters that are the liquid depth parameter, the frequency offset (depending on forcing f...

Systems thinking is one form that interdisciplinarity has adopted since the middle of the twentieth century. It is a catchall term for different postwar developments in a variety of fi elds, such as cybernetics, information theory, game and decision theory, automaton theory, systems engineering, and operations research. These developments concur, however , inasmuch as, in one way or another, th...

Received: 27/01/03; accepted: 14/04/04 ABSTRACT Urinary tract infection (UTI) is a common problem in pregnant woman. This study examined the frequency of UTI in 137 pregnant women attending Al Mukalla maternity hospital from January to ...

b-Glucan is one of the most abundant polysaccharides in fungal pathogens, yet its importance in antifungal immunity is unclear. Here we show that deficiency of dectin-1, the myeloid receptor for b-glucan, rendered mice susceptible to infection with Candida albicans. Dectin-1-deficient leukocytes demonstrated significantly impaired responses to fungi even in the presence of opsonins. Impaired le...

We show that eleven-dimensional supergravity backgrounds with thirty one supersymmetries, N = 31, admit an additional Killing spinor and so they are locally isometric to maximally supersymmetric ones. This rules out the existence of simply connected eleven-dimensional supergravity preons. We also show that N = 15 solutions of type I supergravities are locally isometric to Minkowski spacetime. T...

Editor—Five years ago, when we published our research on the discrimination faced by ethnic minority doctors applying for posts as senior house officers, the Department of Health considered using our methodology to monitor progress in tackling discrimination. At a recent BMA conference to discuss racial discrimination in the medical profession several speakers pointed out that racial discrimina...

The widespread occurrence of endocrine disrupting chemicals (EDCs), such as steroid hormones, in secondary wastewater effluents has become a major concern in the water recycling practice. This paper investigates the risk of steroid hormone breakthrough during nanofiltration membrane filtration in water recycling applications. The results indicate a dynamic equilibrium between adsorption and des...

That functional differentiation is dependent on 3D architecture has become accepted recently. Many papers over the last 50 years have shown that cells cultured in 2D are not representative of the in vivo situation. Structurally, 2D cultu...
