applications of thermoplastic composites have developed extensively. the thermoplastic composites in comparison with the thermoset composites have many advantages. thermoplastic composites can be melted and remolded many times. the duration of manufacturing process of these composites is short, producing very tough material, and the welding ability and multiple recyclings are their further adva...

Although early and appropriate antibiotic therapy remains the most important intervention for successful treatment of septic shock, data guiding optimization of beta-lactam prescription in critically ill patients prescribed with continuous renal replacement therapy (CRRT) are still limited. Being small hydrophilic molecules, beta-lactams are likely to be cleared by CRRT to a significant extent....

We demonstrate a novel pattern that results in bacterial biofilms as a result of the competition between hydrodynamic forces and adhesion forces. After the passage of an air plug, the break-up of the residual thin liquid film scrapes and rearranges bacteria on the surface, such that a ‘Swiss cheese’ pattern of holes is left in the residual biofilm. Bacteria often adhere to surfaces, where they ...

OBJECTIVE The study was conducted to evaluate the long-term results of homograft reconstruction of the left ventricular outflow tract with a cryopreserved aortic homograft in the presence of aortic root abscess associated with a biofilm bacterial infection. METHODS Between January 1987 and December 2003, 161 patients with aortic root abscess underwent freehand aortic valve (FAVR, N = 78) and ...

Residual stresses have become an important player in the field of the structural integrity for many years. Having an exact knowledge of residual stress distributions can be essential in designing the engineering components as unexpected failures are inevitable where such stresses are ignored.  There are many residual stresses measurement techniques including destructive and non-destructive ones...

The disposal of hospital wastewaters, particularly urine with high concentrations pharmaceuticals, is a critical problem. These pharmaceuticals can enter the environment and lead to development superbacteria (in case antibiotics) due inefficiency conventional treatment these aqueous wastes. Hence, this report focuses on scale-up photoelectrochemical (PEC) system equipped Ru-based mixed metal ox...

in this paper, we will give necessary and sufficient conditions for certain hnnextensions of subgroup separable groups with normal associated subgroup to be conjugacyseparable. in fact, we will show that these hnn extensions are conjugacy separable if and onlyif the normalizer of one of its associated subgroup is conjugacy separable.

we prove that if $m$ is a monoid and $a$ a finite set with more than one element‎, ‎then the residual finiteness of $m$ is equivalent to that of the monoid consisting of all cellular automata over $m$ with alphabet $a$‎.

pediatric traumatic limb amputations are rare and their acute and long term management can be challenging in this subgroup of patients. the lengthy and costly hospital stays, and resulting physical and psychological implications leads to significant morbidity. we present a summary of treatment principles and the evidence base supporting the management options for this entity. the initial manage...

in this research, a novel method to decrease micro-residual stresses of fibrous composites by adding carbon nanotubes (cnts) is proposed in detail. the negative coefficient of thermal expansion and the high young’s modulus of cnts can be utilized to counterbalance the process induced residual stresses in composites. to this end, first, the effects of adding cnts to the matrix of fibrous composi...
