The objective of this study was to determine the effects of grasp conditions (types of grasp, grasp width, glove and types of coupling) on maximal pushing force (MPF) and required pinch force (RPF) during snap fit assembly. The results indicated that the type of grasp, the type of coupling and wearing gloves have significant (p

In the present study, nine bis-azo dyes based on 5-arylidene-2,4-thiazolidinone were obtained in two steps, using Knoevenagel condensation and azo coupling reactions. The structure of the dyes was confirmed on the basis of spectral data. Analysis of spectroscopic data shows that there is equilibrium between the azo and hydrazone tautomers for all dyes in solutions. Investigation of antioxidant ...

Studies of La0.7Ca0.3MnO3 epitaxial films on substrates with a range of lattice constants reveal two dominant contributions to the occurrence of colossal negative magnetoresistance (CMR) in these manganites: at high temperatures (T → TC , TC being the Curie temperature), the magnetotransport properties are predominantly determined by the conduction of lattice polarons, while at low temperatures...

Biochemical regulatory networks governing diverse cellular processes such as stress-response, differentiation and cell cycle often contain coupled feedback loops. We aim at understanding how features of feedback architecture, such as the number of loops, the sign of the loops and the type of their coupling, affect network dynamical performance. Specifically, we investigate how bistability range...

Physical coupling between inositol 1,4,5-trisphosphate (IP(3)) receptors and transient receptor potential (Trp) channels has been demonstrated in both transfected and normal cells as a candidate mechanism for the activation of store-mediated Ca(2+) entry (SMCE). We have investigated the properties of the coupling between the type II IP(3) receptor and naturally expressed human Trp1 (hTrp1) in h...

tripropylammonium fluorochromate(vi) (tpafc), is an efficient and new reagent, which isprepared easily and oxidizes thiols to the corresponding disulfides, quickly. the reactions areperformed cleanly and are controlled to stop at the disulfide stage, without over-oxidation andside products. coupling of thiols to their corresponding disulfides, are studied in solution atroom temperature and in s...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...

We use twistor inspired rules to compute the one-loop amplitude for a Higgs boson coupling to any number of negative helicity gluons in the large top mass limit.

Facially amphiphilic urea oligomers were successfully prepared in a one-pot reaction by carbonyl diimidazole (CDI) coupling and showed greater antibacterial activity against both Gram-negative Escherichia coli and Gram-positive Bacillus subtilis than MSI-78.
