The grinding is one of the most important methods that directly affects tolerances in dimensions, quality and finished surface of products. One of the major problems in the material removal processes specially grinding is the heat generation during the process and the residual tensile stress in the surfaces of product. Therefore, optimization of High Efficiency Deep Grinding (HEDG) process is t...

Muscle relaxants are routinely administered during anesthesia. The residual effects of nondepolarizing muscle relaxants must be reversed by the anesthesia provider prior to extubation of the trachea to ensure that patients can safely protect their own airways and maintain adequate ventilation. Many factors can potentiate the effects of muscle relaxants, and each of these factors must be taken i...

background: indoor residual spraying (irs) is functioned as national interventions against malaria in southeastern foci of iran and deltamethrin wp one of the insecticides have been used since past decade. in this study, the residual activity of the wettable granule (wg) was studied on different surfaces in hut scale trial against anopheles stephensi   in iranshahr district, southeastern iran. ...

background and aims: the main cause of many problems in developing countries is related to the provision of safe drinking water. since the health of drinking water is important in the busy centers such as hospitals, clinics and health centers, this study was done to investigate the role of water coolers connected to the municipal system in microbial quality of drinking water in behbahan city. m...

Although each statistical unit on which measurements are taken is unique typically there is not enough information available to account totally for its uniqueness. Therefore heterogeneity among units has to be limited by structural assumptions. One classical approach is to use random effects models, which assume that heterogeneity can be described by distributional assumptions. However, inferen...

The validity of sequential double label deoxyglucose (DG) determinations of local metabolic rate for glucose (IMRglc) was examined by quantifying the degree of trapping of residual first DG tracer during the second experimental period. One sciatic nerve was repetitively stimulated for 25 min, beginning either at the time of the DG injection or 25 min later. IMRglc in the ipsilateral dorsal horn...

To find the residual effects of long term exposure to mercury vapour, neurobehavioural tests were given to ex-mercury miners about 18 years after the end of mercury exposure. Seventy six male ex-mercury miners who had been exposed to high concentrations of mercury vapour (over 1.0 mg/m3) and with a history of mercury intoxication were compared with controls matched for age (within 3 years), sex...

In this work, we introduce a modified Holzapfel-Ogden hyperelastic constitutive model for ventricular myocardium that accounts for residual stresses, and we investigate the effects of residual stresses in diastole using a magnetic resonance imaging-derived model of the human left ventricle (LV). We adopt an invariant-based constitutive modelling approach and treat the left ventricular myocardiu...

Two-dimensional finite element modeling procedures are addressed to predict the residual stresses for multipass welds. A generalized plane strain model with a five-pass weld in a plate and an axisymmetric model with a six-pass girth weld in a pipe are considered. Element rebirth and pass-lumping techniques are employed in both models. The combined heat input using surface and body flux componen...

Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...
