Intravital microscopy has done much to elucidate the cascade of events involved in the recruitment of leukocytes to sites of inflammation. Here we review the physiological relevance of leukocyte rolling and some of the important subtleties of this process, highlighting limitations in our knowledge and directions for future investigation.

In this paper we investigate the properties of generalized bent functions defined on Z2 with values in Zq where q ≥ 2 is any positive integer. We characterize the class of generalized bent functions symmetric with respect to two variables, provide an analogue of Maiorana– McFarland type bent functions in the generalized set up. A class of bent functions called generalized spreads type is introd...

The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...

production of thin steel strips with 0.18-0.26 mm thickness is about 0.75 of annual production of the two stand reversing cold mill, while its efficiency is 60%. this is due to the fact that after montaging the grinded work rolls, rolling thin steel strips (with thicknesses less than 0.18 millimeters) is unavailable. initially, unsuitable surface roughness, the friction between rolls and the st...

OBJECTIVES Cigarette price increases reduce smoking prevalence but as a tobacco control policy are undermined by the availability of lower cost alternatives such as hand-rolling tobacco. The aim of this descriptive study is to explore time trends in the price of manufactured cigarettes and hand-rolling tobacco, and in the numbers of people who smoke these products, over recent years in the UK. ...

L-selectin is a leukocyte cell-surface protein that facilitates the rolling of leukocytes along the endothelium, a process that leads to leukocyte migration to a site of infection. Preventing L-selectin-mediated rolling minimizes leukocyte adhesion and extravasation; therefore, compounds that inhibit rolling may act as anti-inflammatory agents. To investigate the potential role of multivalent l...

By using some finite local rings, we construct some new partial difference sets and relative difference sets on ^-groups where p is any prime. When p = 2, some of the partial difference sets constructed are reversible difference sets which include Dillon's difference sets.

The spatial metaphor can be used as a framework for exploration process, refine their information goals (Foss explaining and designing tools that alleviate disorientation problems in 1989a. Foss 1989b. McAleese 1989). . ~ ~ ~ , ~, hypertext systems. The approach based on this metaphor would involve The disorientation problem occurs when the user 'gets developing tools analogous to navigational ...

Rolling bearings are one of the most important noise and vibration generator into mechanical constructions. Therefore, it is very important to have knowledge of the rolling element bearings influence on the level of noise and vibration in this systems. This paper deals with a basic forms for generation of vibration and noise of rolling element bearing and suggestions of vibration analysis signi...

Technology of round bars rolling on a three-high skew rolling mills allows rolling of standard materials such as steel and aluminum, as well as new materials, especially hard deformable materials. The paper presents the results of theoretical and experimental rolling process of aluminum bars with a diameter of 20 mm. As the stock round bars with a diameter of 25 mm made of aluminum grade 1050A ...
