This study tested the hypothesis that subjects improve their relative stability as they learn a dynamic pulling task. Healthy adult subjects practiced making brief horizontal pulls (<300 ms) on a handle to a range of target forces ranging from 20 to 80 percent of their estimated maximum for 5 days. They were instructed to always keep their feet flat, and begin and end their motion in an upright...

in the modern world today where the margin of error is minimal for the growth and at the same time there is a very competitive and challenging economic environment, it is very significant and crucial that efficiency is being prevailed in the organization through the help of international standards through which the respective organization should maximize their profits and should meet their resp...

Anticonvulsant activity of N-(p-aminobenzoyl)-1,2,3,4- tetrahydro-quinoline (NTQ), a newly synthesized ameltolide analog, was investigated with regards to efficacy and toxicity in mice. Additionally, its effect on NMDA receptors was also performed on NR1a/NR2B expressed in Xenopus oocytes. NTQ, given intraperitoneally, was able to protect the animals in both maximal electroshock seizure and pen...

A driving simulator was used to investigate the effects of simulated glare from the sun on the execution of left-turns at an intersection. The presence of glare resulted in a significant reduction in the safety margin used by drivers (by 0.65 sec on average). The effect of glare was larger for low-contrast than for highcontrast oncoming vehicles. Older drivers (45-60 years) had a significantly ...

abstract the main aim of the paper is to determine the marketing efficiency of poultry industry in karaj. in this research the marketing margin and the marketing efficiency of poultry market in different level of the market in karaj was calculated. the results showed that slaughter houses gain the main part of marketing margin and marking profit. the share of slaughter house was more that 50 pe...

BACKGROUND Traditionally, a safety margin of at least 10 J between the maximum output of the pulse generator and the energy needed for ventricular defibrillation has been used because lower safety margins were associated with unacceptably high rates of failed defibrillation and sudden cardiac death. The Low Energy Safety Study (LESS) was a prospective, randomized assessment of the safety margin...

When approached by a potential predator, individuals must decide when to flee. Individuals could assess risk by monitoring their distance from an approaching threat or by monitoring the expected time that the predator would take to reach them. Theory predicts, and empirical studies support the hypothesis, that some species maymaintain a temporal margin of safety and therefore monitor the expect...
