this paper focused on the characterization of electrochemical behavior of a martensitic stainless steel inthe acidic solutions. for this purpose, electrochemical parameters were derived from potentiodynamicpolarization, mott schottky analysis and electrochemical impedance spectroscopy (eis) techniques.the potentiodynamic polarization results showed that corrosion current density of aisi 420 sta...

Flywheel energy storage has a wide range of applications in grids and transportation. The adoption high-performance components made this technology viable alternative for substituting or complementing other devices. systems are subject to passive discharge attributed primarily electrical machine losses, bearing rolling friction, aerodynamic drag the flywheel rotor. In present study, measurement...

the acute ecotoxicity of a set of mixture samples (washing powders, wastes, fuel extracts etc.) was assessed using four acute ecotoxicity assays with aquatic organisms (daphnia magna, poecilia reticulata, artemia salina and desmodesmus subspicatus). the experimental concentration-response curves were fitted by seven two-parameter sigmoid equations using non-linear regression. the regression per...

the existence of passive makers in kurdish language, similar to that of ancient iranian languages can be very helpful in linguistic studies, language change and finding the nature of passive structures in modern iranian languages such as persian. the writers of this article have found a passive maker in kurdish language and its dialects such as sorani, ardalani, kalhori, ilami and horami that l...

We examined the hypothesis that dendritic voltage-gated channels can reduce the effect synaptic location has on somatic depolarization in response to patterns of short synaptic trains (referred to as location-dependent variability). Three computer models of a reconstructed hippocampal CA1 cell, each of increasing realism and complexity, were used. For each model, the goal was to identify the de...

Is architecture relevant for political theory? That is the key question that structures this excellent collection Political Theory and Architecture, although a number of essays fit broader formulated theme better, namely, concerning relevance organization design our built environment more generally, including but also spatial planning urban design. The demonstrates build not merely passive back...

The bionic design of muscles is a research hotspot at present. Many researchers have designed elastic actuators based on the Hill muscle model, and most them include an active contraction element, passive element series but they need more parametric mechanical structure control under guidance model. In this research, nonlinear cable actuating mechanism in which parameters are optimized model to...

In the “quest” (Delone and McLean 1992) for reliable and practical measures of IS success, a growing stream of research has argued that a key predictor of performance impacts is user evaluations of fit between task requirements and characteristics of the system or technology (Goodhue and Thompson 1995; Vessey and Galletta 1991; Jarvenpaa 1989; Goodhue 1988). The argument is that a better fit pr...
