The purpose of this study was to investigate 1) the effect of feet distance on static postural balance and 2) the location of natural feet distance and its possible role in the relationship of feet distance and postural balance. Static balance tests were performed on a force platform for 100 s with six different feet distances (0, 5, 10, 15, 20, 25 cm). Measures of postural balance included mea...

objective: the knowledge of anatomic landmarks’ positions, including inferior alveolar nerve’s canal, is crucial for dentist, who has to master it. it is important to know the exact location and anatomic variety of this canal for different procedures of mandibular surgeries. the aim of the present study was to evaluate inferior mandibular canal’s anatomic position by cone-beam computed tomograp...

purpose: to compare the results of conventional hang-back technique (chbt) with that of anchored hang-back technique (ahbt) for bilateral lateral rectus (lr) recession in patients with exotropia. methods: in this randomized clinical trial, 60 patients underwent chbt (group 1) or ahbt (group 2) for lr recession (30 patients in each group). preoperative and postoperative deviation, age, sex, the ...

We find the greatest values $alpha_{1} $ and $alpha_{2} $, and the least values $beta_{1} $ and $beta_{2} $ such that the inequalities $alpha_{1} C(a,b)+(1-alpha_{1} )H(a,b)

[Purpose] The purpose of this study was to determine the effects of chewing gum on driving performance in a driving simulator. [Subjects] In total, 26 young licensed drivers participated. [Methods] The driving scenario was typical of an urban environment: a single-carriageway, two-way road consisting of a mix of curved and straight sections, with considerable levels of traffic, pedestrians, and...

Data on underground nuclear explosions have recently become available from modern digital seismic stations installed within the Soviet Union and China. Observations of root mean square (rms) Lg-wave signals for Soviet underground nuclear explosions at the Shagan River Test Site in East Kazakhstan show that the relative amplitudes of the rms signals at stations in Norway, the USSR, and China are...

this investigation was conducted to compare the genetic variation of alfalfa syn0 vs syn1 and ghara yonja (parental cultivar) using seed storage proteins. results of electrophoresis sds-page in seed storage protein, indicated that there are no significant differences between the means of distance intra-population obtained for syn0 and ghara yonja (0.274 ± 0.0045, 0.270 ± 0.0081, respectively) a...

Several widely implemented and tested earthquake early warning algorithms employ empirical equations that relate earthquake magnitudes with groundmotion peak amplitudes and hypocentral distances. This approach is effective to the extent that the offline dataset available for setting the fitting coefficients in those equations is of sufficient quality and quantity. However, to address the proble...
