background: dairy farming work involves frequent use of poor postures. these postures may increase the risk of developing musculoskeletal disorders among dairy workers. objective: to assess postural load during performance of various tasks related to dairy farming. methods: this cross-sectional study was conducted on a dairy farm in iran. in order to assess postural load, tasks related to dairy...

Physical exercise enhances a wide range of cognitive functions in humans. Running-induced cognitive enhancement has also been demonstrated in rodents but with a strong emphasis on tasks that require the hippocampus. Additionally, studies designed to identify mechanisms that underlie cognitive enhancement with physical exercise have focused on running-induced changes in neurons with little atten...

Cryotherapy is often used as an immediate treatment method to relieve the acute pain of soft tissue injuries. The current study aimed to investigate the direct effect of quadriceps muscles cooling with ice spray on plantar pressure variables during stance phase of running in male football players. Seventeen healthy male football players with the mean age of 23.7±3.3 years were recruited to part...

BACKGROUND Creatine supplementation (CS) has been reported to increase body mass and improve performance in high-intensity, short-duration exercise tasks. Research on CS, most of which has come into existence since 1994, has been the focus of several qualitative reviews, but only one meta-analysis, which was conducted with a limited number of studies. PURPOSE This study compared the effects o...

The problem of scheduling a set of tasks on two parallel and identical processors is considered. The executions of tasks are constrained by precedence relations. The running times of the tasks are independent random variables with a common exponential distribution. The goal of scheduling is to minimize the makespan, i.e. the maximum task completion time. A simple optimal preemptive policy is pr...

Running increases the formation of new neurons in the adult rodent hippocampus. However, the function of new neurons generated from running is currently unknown. One hypothesis is that new neurons from running contribute to enhanced cognitive function by increasing plasticity in the adult hippocampus. An alternative hypothesis is that new neurons generated from running incorporate into experien...

It has been observed that grammaticality judgments do not necessarily reflect relative corpus frequencies: it is possible that structure A is judged as more grammatical than structure B, whereas at the same time structure B occurs more often in actual language data than structure A. In recent work (Boersma & Hayes 2001), we have used Stochastic Optimality Theory to model grammaticality judgment...
