injecting local anesthetic at the seeking current would be appealing.it would save time and avoid potentially dangerous manipulations of the needle. this study aimed to test the hypotheses that in vertical infraclavicular block, injecting local anesthetic at a seeking current of 0.8 ma would produce the same quality of block as injecting at ≤0.5ma. a total of sixty asa i -iii adult patients sch...

The spontaneous electroluminescence emission of InAs light-emitting diodes ~LEDs! operating at 3.3 mm was studied as a function of applied hydrostatic pressure. An enhancement of a factor of almost four in radiative efficiency at room temperature was observed in the range 0 to 10 kbar. Analysis of the dependence of electroluminescence emission intensity on hydrostatic pressure at constant curre...

Neurostimulation is rapidly emerging as an important treatment modality for psychiatric disorders. One of the fastest-growing and least-regulated approaches to noninvasive therapeutic stimulation involves the application of weak electrical currents. Widespread enthusiasm for low-intensity transcranial electrical current stimulation (tCS) is reflected by the recent surge in direct-to-consumer de...

sistan plain is affected by desertification and this phenomenon has serious impacts on roads and socio- economic activities of local people of this region. the main purpose of this study is estimating the current and potential desertification intensity of niatak region of sistan based on micd method. that, through it the working units of this region were prepared as the base map for evaluating ...

Existing studies that consider the techno-economics of residential heating systems typically focus on their performance within present-day energy systems. However, the energy system within which these technologies operate will need to change radically if climate change mitigation is to be achieved. This article addresses this problem by modelling small-scale heating techno-economics in the cont...
