in order to quantify of schooling behavioral responses of rosy barb (puntius barbus) subjected to acute decreasing temperature stress monitored by computer- vision system. four aquaria as duplicate with a density of 30 fish per unit were used for rearing of fish in normal and stress conditions. some geometric schooling parameters such as average location of center gravity school and distance of...

This study uses US survey data (NLSY) and Swedish register data to estimate the relationship between returns to schooling and ability for each country separately. A significant and positive relationship is found for Sweden but not for the US. The purpose is to propose an explanation for why such differences might occur. While many studies have focused on whether credit constraints result in ine...

Using US survey data (NLSY) and Swedish register data the relationship between returns to schooling and ability is estimated separately for each country. A significant and positive relationship is found for Sweden, but not for US. The purpose of this study is to propose an explanation to why such differences might occur.

This article applies the standard deviation of partial signal (SDPS) plots of electrochemical noise (EN) current signals originating from corrosion events on the symmetrical and asymmetrical electrodes made of uncoated and polypyrrole (PPy)-coated mild steel alloy in 4000 ppm NaCl+1000 ppm NaNO2 solution. Signal recording was performed after 30, 60, 90 min and 24 h from immersion...

Methods To measure the muscle activations of the C6, T7 and L5 paraspinal muscles and lumbar multifidus during standing, EMG (Keypoint, Medrtonic, USA) was used. After breathing was calmed down, muscle activation during standing on the ground with bare foot was measured. Subsequently, muscle activation during standing wearing shoes with 8cm Wedge heel, Setback heel and French heel were measured...

brown discharge escaped. The whole of the foot was swollen and congested, and the femoral glands were inflamed. The temperature on admission was 103*2?, the pulse was feeble and rapid (120 beats to the minute), and the man was sallow in appearance, with the anxious expression usual in cases of severe septicaemia. He o-ave a history of having trodden in bare feet?upon a large thorn whilst cuttin...

objectives: the aim of this study was to determine the prevalence of flat foot in a population of 7-12 year old students and to investigate the relationship between flat foot and age and sex. methods: in this cross-sectional study, a total of 945 students (460 girls and 485 boys) were examined. the presence of flatfoot and the degree of its severity according to tachdjian's system of gradi...

Posterior-anterior body weight shift during stance phase of human overground locomotion was investigated by recording sole-floor reaction force from five anatomically discrete points with strain gauge transducers of 14 mm diameter attached firmly to the sole of bare foot. At first the subject was asked to walk straight on the laboratory floor at his/her preferred velocity. Then the subject was ...
