background :    although, nontuberculous mycobacteria can cause disease in different organisms, they usually are not reported in most countries because scientists in general consider them as non-pathogens. but, increasing nontuberculous mycobacteria diseases occurrence has changed this belief. nevertheless, there is no meta-analysis review about prevalence of nontuberculous mycobacteria in iran...

Polychlorinated biphenyls (PCBs) are persistent contaminants that exist as complex mixtures in the environment. One problem faced by risk assessors is that the possible interactive effects of specific PCB congeners and related chemicals found in environmental and biological samples have not been systematically investigated. Some PCBs perturb Ca2+ homeostasis and cause protein kinase C (PKC) tra...

In this study, a carbon nanotube (CNT) buckypaper was interleaved in carbon-fiber-reinforced polymer (CFRP) composite to improve the interlaminar fracture toughness. Interleaving film of laminate-type poses risk deteriorating in-plane mechanical properties. Therefore, shear modulus and strength were measured prior estimating To evaluate effect on toughness CFRP, double cantilever beam (DCB) end...

Many sequential decision-making problems in communication networks such as power allocation in energy harvesting communications, mobile computational offloading, and dynamic channel selection can be modeled as contextual bandit problems which are natural extensions of the well-known multi-armed bandit problem. In these problems, each resource allocation or selection decision can make use of ava...

In this paper fracture surface of the fatigue delamination have been investigated. Fatigue delamination tests were performed on the crabon/epoxy under different stress ratios. Samples were cut from the DCB specimens and analyzed in Laser Confocal Scanning Microscope. The analysis was used to measure the roughness values. Different fractographic features observed in the study are discussed.

Abstract Dynamic covalent bond-based shape memory polymers (DCB-SMPs) are one of most important SMPs which have a wide potential application prospect. Different from common strong bonds, DCBs own relatively weak bonding energy, similarly to the supramolecular interactions noncovalent and can dynamically combine dissociate these bonds. DCB-SMP solids, be designed respond for different stimuli, p...

The molecular signals that determine the position and timing of the cleavage furrow during mammalian cell cytokinesis are presently unknown. We have studied in detail the effect of dihydrocytochalasin B (DCB), a drug that interferes with actin assembly, on specific late mitotic events in synchronous HeLa cells. When cleavage furrow formation is blocked at 10 microM DCB, cells return to interpha...

The utilization of simulation in the design of systems combining different parts (heterogeneous systems) contributes with the validation, verification, and observation of the behavior of these parts (individually) and of the cooperation between them. The differences between the parts (elements) that compose the model of representation (of a system) make these tasks more complex due to three mai...
