the effect of rare earth (re) elements, including ce and la, on the sorption properties of zr-co getters was investigated in this work. the phase evolution, microstructural characteristics of getter powders were studied by means of x-ray diffraction method, scanning electron microscopy (sem) and energy dispersive x-ray spectroscopy (eds). the nanostructured zr3co intermetallic compound has been...
reduced-activation ferritic/martensitic steels have been developed by replacing molybdenum by tungsten and niobium by tantalum in commercial elevated-temperature cr–mo steels to reduce half-life of radioactive isotopes. the objective of this study was to investigate tensile properties of a reduced-activation ferritic/martensitic steel (9cr-2wvta) in normalized-tempered (nt) and quenched-tempere...
the thermal degradation of polyethylene (pe) was carried out in the absence and presence ofcatalystes x-zeolite and silica-alumina at different temperatures. the optimum pe/catalysisratio was 0.25:0.05 g/g, which produced highest degradation value. pe and pe/catalysis werecharacterized by thermogravimetric analysis. the thermal degradation properties of polymerhave been studied by infrared spec...
the kinetics and mechanism of the reaction of 5-nitro-1h-benzo[d] imidazole to produce 6-nitro-1h-benzo[d] imidazole was studied by employing hybrid meta-density functional theory. mpwblk/6-31+g** level calculations were carried out to obtain energies and optimize the geometries of all stationary points along the pes, and determine the harmonic vibrational frequencies. two transition states (ts...
background : biomechanical factors are known to be important in knee osteoarthritis (oa) development and progression. this study was designed to determine changes of hamstrings muscle activation, knee adduction moment and ankle rotation angle in two knee osteoarthritis (mild and moderate) and a healthy control group. methods: 16 females (10 with mild and 6 with moderate medial knee osteoarthr...
BACKGROUND Recently, the expression of proteinase-activated receptor 2 (PAR2) has been shown to be essential for activin receptor-like kinase 5 (ALK5)/SMAD-mediated signaling and cell migration by transforming growth factor (TGF)-β1. However, it is not known whether activation of non-SMAD TGF-β signaling (e.g., RAS-RAF-MEK-extracellular signal-regulated kinase (ERK) signaling) is required for c...
abstract background and purpose: according to the reported problems in area of the inappropriateness of water quality which used for washing and staining of car apparatuses in a car factory, this research was carried out for identification of physical, chemical, and microbiological characteristics of the consumed water in babol car factory, iran. materials and methods: physical and chemical par...
background: gait disorder is a common motor complication after stroke. studies have revealed that conventional physiotherapy cannot manage this disorder efficiently; therefore, more studies regarding efficient treatment protocols are crucial. the purpose of this study was to investigate the effect of compelled weight-bearing approach on muscle activation patterns during walking in individuals w...
Background & Aims: One of the concepts that has been recently emphasized in the care of chronic diseases such as chronic kidney disease (CKD) is the activity of patient in his/her health management, which is called patient activation. Knowing the level of patient activation can help physicians and nurses implementing high quality care and proper patient education. The aim of this study was to e...
Our previous work identified the inner basket of the NPC as a physical activation/protection station for force-tethered, epigenetically silenced genes. Here we show that a specific nucleopore-to-gene-promoter interaction (Nup-PI) is an early physiological event of gene activation. Nup-PI was discovered with chromatin endogenous cleavage (ChEC) experiments that mapped in vivo the genomic interac...
