echis carinatus (saw-scale viper) is one of the most venomous snakes in asia and some parts of the africa with deadly hemotoxic venom. it has been reported that suramin, an antitrypansomiasis drug, can inhibits the toxic effects of some snake venoms. this study was conducted to evaluate the antagonistic effects of suramin against the venom of the iranian snake echis carinatus. adult albino mice...

Cold rolling of steel is one of the most important metal forming processes so an accurate control of its parameters during the process is necessary. In this paper, the friction coefficient has been proposed as a function of cold rolling parameters such as forward slip, forward and backward tensile stresses ,strip thickness, static deformation, resistance of strip before and after rolling ,strip...

Recently, recycling endosomes have emerged as a key components required for the successful completion of cytokinesis. Furthermore, FIP3 (family of Rab11-interacting protein 3), a Rab11 GTPase-binding protein, has been implicated in targeting the recycling endosomes to the midbody of dividing cells. Previously, we have shown that FIP3/Rab11-containing endosomes associate with centrosomes until a...

In this work, cold-rolling was utilized to induce a high density of crystal defects in Al0.3CoCrFeNi high-entropy alloys. The effects annealing temperature on static recrystallization, precipitation behavior and mechanical properties were investigated. With increasing from 590 °C 800 °C, the area fraction recrystallized region increases 26.9% 93.9%. Cold-rolling deformation largely promotes B2 ...

The objective of this research was to develop a new method for predicting the number roller passes and degree compaction asphalt layer from perspective energy. relationship between energy density quantified using gyratory compactor. Prediction models utilization coefficient product rolling resistance were established based on test section. prediction procedure proposed. Test results showed pred...

We report laboratory experiments on rippled granular surfaces formed under rolling wheels. Ripples appear above a critical speed and drift slowly in the driving direction. Ripples coarsen as they saturate and exhibit ripple creation and destruction events. All of these effects are captured qualitatively by 2D soft-particle simulations in which a disk rolls over smaller disks in a periodic box. ...

BACKGROUND Myosin II, a conventional myosin, is dispensable for mitotic division in Dictyostelium if the cells are attached to a substrate, but is required when the cells are growing in suspension. Only a small fraction of myosin II-null cells fail to divide when attached to a substrate. Cortexillins are actin-bundling proteins that translocate to the midzone of mitotic cells and are important ...
