Gender differences in a psychometrical and in a chronometrical mental rotation test and in a standardized math test were investigated with a sample size of 109 boys and girls aged 7 or 8 years. The results revealed gender differences in all accuracy-based measures, i.e., in the paper-pencil mental rotation test, in the math test, and in the error rate of the chronometrical test. In line with th...

In this article a comparative study is carried out between three different types of detectors and feature descriptors on a mobile tracked robot. The detectors and descriptors are SIFT, SURF and ORB. The metrics used as a comparison are: processing time, resistance to noise and invariance to rotation. The experiments show that the ORB technique is the fastest obtaining similar results in the res...

Sixty-four tree nut samples (almonds, pecans, pine nuts, and walnuts) and 50 dried fruit samples (apricots, cranberries, papaya, pineapple, and raisins) were purchased from local supermarkets and analyzed for fungal contamination using conventional culture as well as molecular methods. The results of our study showed that the highest yeast and mold (YM) counts (5.34 log10 CFU g(-1)) were found ...

A gray line that rotated about its own center against a stationary background of vertical stripes appeared to double in perceptual speed as it rotated through the vertical position and thus momentarily aligned with the background. Four factors may contribute to this speed-up: (i) landmarks, in which the tip of the moving vertical line moves horizontally across the maximum number of stationary s...

Purpose: Neck pain is associated with gait disturbances. The first aim of this study was to examine spatiotemporal parameters, pelvic movements and symmetry during single dual task conditions in persons CINP compared healthy subjects (HS). second investigate the relationship between disability CINP.Methods: Thirty-one individuals (mean age 22.06±1.38 years, range 18-56 years) 24 HS 22.60±1.51 1...

Actin-based motility of the Grampositive bacterium Listeria monocytogenes is an analog of eukaryotic cell motility and has long been the subject of biochemical and biophysical investigations (reviewed in [1]). Only one bacterial factor—ActA—is required for the movement of L. monocytogenes [2–4]. Biophysical mechanisms have been proposed to explain the conversion of actin polymerization into pro...

We study the interplay between rotation and openness for mode coupling in wavelength-scale microcavities. In cavities deformed from a circular disk, the decay rates of a quasidegenerate pair of resonances may cross or anticross with increasing rotation speed. The standing-wave resonances evolve to traveling-wave resonances at high rotation speed, however both the clockwise (CW) and counterclock...

Background. The badminton forehand overhead jump smash is one of the high speed and powerful motions among various racket sports. Objectives. The purpose of this study is to analyze the effect of fatigue on the kinematic variable movement changes during overhead jump smash in badminton. Methods. This study is descriptive quantitative research with the pre-test and post-test design methods use...

To improve objectivity and speed of current antifungal mold susceptibility testing, the yeast Rapid Susceptibility Assay (RSA) was adapted for Aspergillus species. The RSA is based on glucose utilization in the presence of an antifungal drug. Aspergillus fumigatus conidia were incubated in 0.2% glucose RPMI 1640 containing 0.03 to 16 micro g of amphotericin B or itraconazole/ml. Drug-related in...
