This study used a subject-specific model with eight segments driven by joint torques for forward dynamics simulation to investigate the effects of initial conditions and takeoff technique on the performance of running jumps for height and distance. The torque activation profiles were varied in order to obtain matching simulations for two jumping performances (one for height and one for distance...

Scale height is an important parameter in characterizing the shape of the ionosphere and its physical processes. In this study, we attempt to examine and discuss the variation of scale height, H m , around the F-layer peak height during high solar activity at the northern crest of the equatorial ionization anomaly (EIA) region. H m exhibits day-to-day variation and seasonal variation, with a gr...

Gas-liquid chromatography (GLC) is an effective method for the measurement of total serum cholesterol. Its use in the clinical laboratory, however, requires careful attention to many variables (flow rate, sample size, sensitivity of solvent and choice of the quantitation method, i.e. peak-height ratio vs. peak height). This report evaluates the effect of these variables on the quantitation of s...

The purpose of this investigation was to determine the relationship between relative net vertical impulse and jump height in a countermovement jump and static jump performed to varying squat depths. Ten college-aged males with 2 years of jumping experience participated in this investigation (age: 23.3 ± 1.5 years; height: 176.7 ± 4.5 cm; body mass: 84.4 ± 10.1 kg). Subjects performed a series o...

Thrombin generation was studied in paediatric patients with congenital heart disease (CHD) undergoing cardiac surgery using the calibrated automated thrombography (CAT) in terms of the lag time until the onset of thrombin formation, time to thrombin peak maximum (TTP), endogenous thrombin potential (ETP), and thrombin peak height. The suitability to determine the coagulation status of these pat...

The pasting of commercial maize starches was found to be a biphasic phenomenon, exhibiting an expected first viscosity peak as well as an unexpected, relatively large second viscosity peak under specific cooking conditions when using a Rapid Visco Analyser (RVA). The second peak formed at long holding times (between 32 and 45 min), holding temperatures within the range of 82 to 95 °C, starch co...

There is a lack of sufficient information on cotton responses to time and amount of foliar application of potassium (K) under salt stress environment, The objective of this study was to investigate the effects of potassium (as Solupotasse 50% K2O and 18% S) rate and application time on yield and yield components of cotton under saline field condition. A factorial experiment based on randomized ...

in the management and evaluation of asthma, simple instruments for measurements of peak expiratory flow rate (pefr) are necessary. the aim of this study was to determine normal pefr of the healthy children in babol, iran. this study was randomly done on 1050 students (primary and secondary schools) in babol. mini-wright peak flow meter was used for measurement of pefr. the range of age, weight ...

Background: Diverse indicators have been used to predict growth in children. Skeletal parameters, such as hand wrist bones ossification, have been considered to cause an additional radiation exposure. To avoid such situation, new approaches as the cervical vertebrae maturation have been proposed. Aims & Objective: The aim of this study was to investigate a correlation between the enlargement of...

In explosive contractions, neural activation is a major factor in determining the rate of torque development, while the latter is an important determinant of jump performance. However, the contribution of neuromuscular activation and rate of torque development to jump performance in children and youth is unclear. The purpose of this study was to examine the relationships between the rate of neu...
