pressure refers to the feelings an athlete has about performing in a competitive situation. the primary aim of this study was to examine kinematic changes of tennis serves in increasing competitive pressure. 20 semi-professional right-handed male tennis players completed 120 serves under low (normal) and high competitive pressure phases. pressure checks (heart rate and perceived competitive sta...

INTRODUCTION The GENEA shows high accuracy for classification of sedentary, household, walking, and running activities when sampling at 80 Hz on three axes. It is not known whether it is possible to decrease this sampling frequency and/or the number of axes without detriment to classification accuracy. The purpose of this study was to compare the classification rate of activities on the basis o...

Forkhead activin signal transducer (FAST) is a member of the winged-helix family of DNA-binding proteins that has been implicated in mesoderm induction and left-right axis specification during embryonic development in Xenopus and mouse. We have cloned and characterized a zebrafish FAST homolog. Zebrafish fast is expressed maternally and zygotically. Transcripts start regionalizing and decline i...

Left-right (L/R) patterning is crucial for the proper development of all vertebrates and requires asymmetric expression of nodal in the lateral plate mesoderm (LPM). The mechanisms governing asymmetric initiation of nodal have been studied extensively, but because Nodal is a potent activator of its own transcription, it is also crucial to understand the regulation required to maintain this asym...

ultrasonography is a relatively easy, safe and non-invasive examination method which can be used in diagnosis of ocular disorders as complementary to routine ophthalmic examinations. as there has been no collated study undertaken on the normal measurements of ocular structures in caspian miniature horse, obtaining these measurements could be a benchmark to diagnose some of the diseases and eye ...

in most legal systems, the right to cancel the contract is provided for consumer in electronic contracts with slight variations. in article 6 of the european :union: directives on the protection of consumers in respect of distance contracts, such right is provided too. article 37 of iranian ec code considered for the right of withdrawal is very close to the above terms. there is a controversy a...

We commend Bennebroek Evertsz' et al.1 on their work comparing a version of the physician-completed Simple Clinical Colitis Activity Index (SCCAI)2 with a patientcompleted version. We, too, believe this is a way of moving toward patient-centered and patient-initiated care. The 2 scores as used here, however, show deviation from the original Index in both use and redesign. Firstly, we note that ...

original article   one type of electromagnetic fields, based on frequency range, is extremely low frequency (elf) fields. there are lots of reports about measuring elf-magnetic field (mf) in substations, power plants, cities and etc. this study aimed to compare the difference between measurement of three-axis and single-axis probe mf meters. elf-mf was measured by tes-1394 mf tester (three-axis...
