the existence of some geometrically imperfect members, like initial curvature in a double layer space structures with hundreds or thousands of members is almost inevitable. these imperfections give rise to loss of load bearing capacity of double layer space structures. to evaluate the effect of initial member imperfection on load bearing capacity of double layer space structures and their failu...
The follicle-associated epithelium (FAE) secretes chemokines important in the recruitment of various cell types including CCL20 (MIP-3alpha). CCL20 is chemotactic to the CD11b(+) dendritic cells (DCs) distributed in the subepithelial dome regions of the Peyer's patches, and mice deficient in the receptor for CCL20, CCR6, have been reported to be devoid of the CD11b(+) DCs in the dome regions. H...
The study of the development of the mammary gland at the molecular level in the animal is difficult because of the complex tissue organization of the gland. We have previously developed an in vitro system for genetic analysis of mammary cell differentiation, based on the cell line LA7 clonally derived from a rat mammary adenocarcinoma. This cell line, after induction with DMSO, differentiates f...
BACKGROUND The present study was undertaken to determine the effect of recombinant human bone morphogenetic protein-2 (rhBMP-2)-loaded biodegradable membranes on bone augmentation in a rabbit calvarial model. METHODS Five microg of rhBMP-2 was loaded into a stiff hemispherical dome membrane made of poly(L-lactide) and tricalcium phosphate (PLLA/TCP). The release kinetics of rhBMP-2 from the m...
The most important characteristic of dome and factors influencing it in the Islamic Iranian architecture that is different from other courses is construction and construction methods of them. Over time, different factors are involved in the process of formation of the domes. It is one of the factors influencing the structure of Iranian-Islamic domes. By examining the structure of Iranian-Islami...
This paper deals with the experimental investigations of the in-cylinder tumble flows in an unfired internal combustion engine with a flat piston at the engine speeds ranging from 400 to 1000 rev/min., and also with the dome and dome-cavity pistons at an engine speed of 1000 rev/min., using particle image velocimetry. From the two-dimensional in-cylinder flow measurements, tumble flow analysis ...
