We analyzed individual motor units during electrically elicited cramp contractions with the aim of characterizing the variability and degree of common oscillations in their discharges. Intramuscular and surface electromyographic (EMG) signals were detected from the abductor hallucis muscle of 11 healthy subjects (age 27.0+/-3.7 yr) during electrically elicited cramps. In all, 48 motor units wer...

background: temporal variation of stroke onset is suggested in some studies contained somewhat varieties. it is proposed that some predisposing changes occur in some ascertained times consequently resulted in stroke occurrence in some special times. objective: to determine the circadian and circaseptan variation of stroke onset. materials and methods: this cross sectional study was conducted fr...

Among the structural and non-structural methods of flood control, rockfill dams are a kind of detention structures that increase travel time and reduce the maximum instantaneous flood discharge. Due to the rapid and automatic effect of these dams, flood reduction happens more quickly. In this research, the best arrangement of rockfill dams at Taleghan basin was determined based on the cost of r...

Prediction of the peak discharge debris flow is one most important factors in mitigating disasters. Currently, empirical methods based on relationship between and total volume (magnitude) for many events are used to estimate planning or designing countermeasures Japan. In order with high accuracy, monitoring sensors load cell pressure sensor (hereafter referred as a DFLP system), was installed ...

In this paper, we propose to optimize manufacturing methods of memory cells by produced silicon nanoparticles via electrical spark discharge of silicon electrodes in water to reduce the energy consumption for low power applications. The pulsed spark discharge with the peak current of 60 A and a duration of a single discharge pulse of 60 µs was used in our experiment. The structure, morphology, ...
