Sixty Pseudomonas aeruginosa isolates were tested by the agar disk diffusion, AMS Vitek GNS-V flex panel (Vitek Systems, Inc., Hazelwood, Mo.), and agar dilution methods. Although the results of aminoglycoside tests were satisfactory, those of piperacillin and cefoperazone by Vitek GNS-V (T2.05 program) were not acceptable.

Direct formic acid fuel cells (DFAFCs) are one of the most promising power sources due to its high conversion efficiency; relatively low carbon emissions, toxicity, and flammability; convenience; low-cost storage transportation. However, key challenge large-scale commercial applications is poor performance catalyst’s preparation cost. In this study, a new sandwich-structured Pd/polypyrrole-grap...

In this article, the author studies the regularity of 3D generalized Navier-Stokes (GNS) equations with fractional dissipative terms (−∆)αu. It is proved that if div(u/|u|) ∈ Lp(0, T ;Lq(R3)) with 2α p + 3 q ≤ 2α− 3 2 , 6 4α− 3 < q ≤ ∞. then any smooth on GNS in [0, T ) remains smooth on [0, T ].

Motivated by deformation quantization we investigate the algebraic GNS construction of ∗representations of deformed ∗-algebras over ordered rings and compute their classical limit. The question if a GNS representation can be deformed leads to the deformation of positive linear functionals. Various physical examples from deformation quantization like the Bargmann-Fock and the Schrödinger represe...

Recently, environment-friendly synthesis of gold nanoparticles (GNPs) has been extensively explored by biologists and chemists. However, significant research is still required to determine whether "eco-friendly" GNPs are beneficial to human health and to elucidate the molecular mechanisms of their effects on human cells. We used human neuronal SH-SY5Y cells to show that treatment with Kalopanac...

The unmanned aerial vehicle (UAV) is a promising enabler of Internet Things (IoT) owing to its highly flexible features. Combined with wireless power transfer (WPT) techniques, UAV can provide energy for IoT nodes, which extend the lifetime constrained communication systems. This paper studies resource and trajectory optimization in UAV-powered systems, consists two UAVs ground nodes (GNs). sys...

The production of novel catalyst support materials could open up new ways to enhance the catalytic activity by reduced catalyst loadings. Nanocomposites composed of conducting polymers reinforced with graphene nanosheets (GNS) or graphite oxide (GO) sheets can be potential fuel cell electrodes as an alternative to commercial fuel cell electrodes. Polymer electrolyte membrane fuel cells (PEMFCs)...

The holonomy-flux *-algebra was recently proposed as an algebra of basic kinematical observables for loop quantum gravity. We show the conventional GNS construction breaks down when the the holonomyflux *-algebra is allowed to be a Jordan algebra of observables. To remedy this, we give a Jordan GNS construction for the holonomy-flux *-algebra that is based on trace. This is accomplished by assu...

Gradient nanostructures (GNSs) have been optimized in recent years for desired performance. The diffusion behavior in GNS metals is crucial for understanding the diffusion mechanism and relative characteristics of different interfaces that provide fundamental understanding for advancing the traditional surface alloying processes. In this paper, atomic diffusion, reactive diffusion, and surface ...

In this work, the performance of graphene nanosheets (GNs) and graphene oxide (GO) nanosheets, as a support for palladium nanoparticles (PdNPs) toward oxygen reduction reaction (ORR), was studied. The graphene nanosheets were functionalized by a new and simple method. The PdNPs were synthesized on a glassy carbon electrode (GCE) modified with GNs or GO via a potentiostatic method; without using...
