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 ...

The molecular mechanisms underlying leukocyte recruitment in large arteries have been extensively studied using histological techniques on fixed tissues. However, there are no reports that address the dynamics of leukocyte recruitment in large arteries in vivo. We developed an intravital microscopy technique for direct observation of leukocyte-endothelium interactions in the mouse aorta. Circul...

The microstructure evolution during cold rolling of commercial purity AA1050 aluminum is investigated through numerical simulations. A finite strain elasto-viscoplastic constitutive model is employed, where the dislocation density and average grain size are taken as variables characterizing the deformed microstructure. Grain size evolution due to dynamic recrystallization is considered and the ...

[Purpose] This paper provides information about the theory and technique of Yamuna Body Rolling. In order to treat physical problems, using the specialized Yamuna Body Rolling balls, people can target superficial skin, fasciae, muscle fibers, tendons, ligaments, bones, internal organs, and the nervous system by themselves. The extraordinary effect of Yamuna Body Rolling is its multidimensional ...

An important generally recognized factor in improving the quality of cultivation recent years is elastic fastening working organs. It believed that bodies fixed with struts make intense vibrations, which leads to an improvement soil crumbling and a decrease traction resistance similar vibrations vibrator. However, paws on rack when receive deviation from set processing depth by 10-15% more than...

The main purpose of this study was to investigate employees and managers’ satisfaction of transportation system in the steal and rolling Units of Saba in Mobarakeh Steel Company using the intuitionistic fuzzy data. The statistical population included the personnel of Saba Steel and Rolling Units from Mobarakeh Steel Company including 1800 people.
