in this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (fg) single-walled carbon nanotubes (swcnts) was carried out in radial direction while subjected to a steady state thermal field. the swcnts were assumed aligned, straight with infinite length and a uniform layout. two types of variations in the volume fr...

in this article, the elasto-plastic analysis of thick walled fg tanks subjected to internal pressure is elaborated. today, thick walled tanks containing liquids with high pressure are used in the chemical industries. the high internal pressure causes part of the thickness of reservoir to yield; therefore, we need the elasto-plastic analysis. in this study, elasto-plastic behavior of fg cylindri...

Nucleoporins with phenylalanine-glycine repeats (FG Nups) function at the nuclear pore complex (NPC) to facilitate nucleocytoplasmic transport. In Saccharomyces cerevisiae, each FG Nup contains a large natively unfolded domain that is punctuated by FG repeats. These FG repeats are surrounded by hydrophilic amino acids (AAs) common to disordered protein domains. Here we show that the FG domain o...

In this article, we propose a new distributed sensors-based multi-target geolocation and tracking technique. The proposed technique is joint time-of-arrival (TOA) direction-of-arrival (DOA) factor graph (FG) for (FG-GE), which further combined with another FG extend Kalman filtering (FG-GE-EKF) tracking. Two-dimensional (2D) three-dimensional (3D) scenarios are considered. the FG-GE part, senso...

In this solid-phase enzymoimmunoassay for estrone in saliva, microtiter plates are used after extraction of the sample with diethyl ether. No chromatographic step is involved. The detection limit of the assay is 450 fg per well (33 pmol/L). Intra- and interassay coefficients of variation for the assay of low, medium, and high concentrations of estrone in saliva were respectively 4.2, 12.7; 5.2,...

This competitive, solid-phase enzymoimmunoassay for testosterone in saliva is carried out on microtiter plates and involves no chromatographic or extraction steps. With an overnight incubation the detection limit of the assay is 230 fg per well (16.1 pmol/L). There was a good correlation (correlation coefficient 0.95) between testosterone concentrations measured with and without prior extractio...

The effect of flaxseed gum (FG) on the rheological and nonlinear stress response behaviors of mixed soy protein isolate (SPI)-flaxseed gum (FG) dispersions were studied. Results showed that the viscosity of the SPI-FG mixed dispersions increased significantly with increase in the FG concentration. Both the shear stress and the apparent viscosity values as a function of shear rate were fitted we...

Nucleocytoplasmic transport has been the subject of a large body of research in the past few decades. Recently, the focus of investigations in this field has shifted from studies of the overall function of the nuclear pore complex (NPC) to the examination of the role of different domains of phenylalanine-glycine nucleoporin (FG Nup) sequences on the NPC function. In our recent bioinformatics st...

Entropy guards pore T he rapid fl uctuations of fl exible FG repeat–containing nucleoporins (FG Nups) form an entropic barrier to would-be entrants into the nuclear pore complex (NPC), according to Roderick Lim (University of Basel, Switzerland) and colleagues. FG Nups, which consist of large natively unfolded domains, are the pore’s gatekeepers—they keep out proteins that are not bound to tran...
