1. In this study we have recorded the activity of motor units of the important muscles acting across the elbow joint during combinations of voluntary isometric torques in flexion/extension direction and supination/pronation direction at different angles of the elbow joint. 2. Most muscles are not activated homogeneously; instead the population of motor units of muscles can be subdivided into se...

conclusions treatment of neonatal respiratory failure with high rate mechanical ventilation may reduce some complications. results intraventricular hemorrhage (ivh) and air leak (e.g. pneumothorax) were less in hfppv group than conventional group (p = 0.012 and p = 0.038). the mean time needed for mechanical ventilation was lower in hfppv group, but this difference was not statistically signifi...

With the rapidly expanding use of fluorescent lamps (FLs) and increasing interest in conservation and sustainable utilization of critical metals such as rare earth elements (REEs), the recovering of REEs from phosphors in waste FLs is becoming a critical environmental and economic issue. To effectively recycle REEs with metallurgical methods, mechanical activation by ball milling was introduced...

In this study, pure powders such as molybdenum, silicon, aluminum and titanium carbide were utilized to produce MoSi2 compound, MoSi2 /20 Vol % TiC composite, MoSi2-x Al alloyed compound and MoSi2-x Al/20 Vol % TiC alloyed composite. The initial powders were mixed in specified ratios, and then, were activated by mechanical milling. Milled powders were compacted, synthesized and sintered in the...

Calcium plays an important regulatory role in olfactory signal transduction. Many investigations into the regulation of the olfactory signaling pathway have been performed using fractions enriched in ciliary membranes from olfactory sensory neurons. The traditional method of preparing ciliary fractions uses high calcium concentrations, thought to dislodge cilia from the dendritic knobs of the o...
