Head and neck posture is an important factor in neck pain related to computer use; however, the evidence for an optimal posture is unconvincing. This study measured the 3-D postures of 36 young adults during use of three different display heights. Cervical extensor muscle strain was estimated using modelled gravitational load moments and muscle capacities. The influence of more or less upper vs...

BACKGROUND Adolescent pregnancy and childbirth are associated with increased risk and challenges for both mothers and birth outcomes. OBJECTIVE To investigate the associations of growth change over time with parenting factors and to compare the differences between children born to adolescent and adult mothers in Taiwan. MATERIALS AND METHODS The dataset retrieved from Taiwan birth cohort st...

An investigation into the nutritional anthropometry of preschool children of poor socioeconomic status was carried out in a rural community of India by door-to-door visits. All measurements--height, weight, left mid-arm girth, and chest and head circumferences--were far below local as well as international standards. By comparison with the Harvard standard, about 53% of the children were below ...

The purpose of the present study was to investigate the influence of estrogen receptor alpha gene polymorphism and estradiol on height and bone density during and after puberty in males. Using the restriction enzymes XbaI and PvuII, the allelic variants XX, Xx, xx, PP, Pp, and pp were identified in 90 Caucasian boys 16.9+/-0.3 yr of age (mean +/- SD). Bone mineral density (BMD; g/cm2) of the to...

OBJECTIVE The goal of this study was to generate and report standardized growth curves for weight, height, head circumference, and BMI for non-growth hormone-treated white male and female US subjects with Prader-Willi syndrome (PWS) between 3 and 18 years of age and develop standardized growth charts. METHODS Anthropometric measures (N = 133) were obtained according to standard methods from 1...

determining general and specific combining ability of lines is necessary to use them as parents of hybrid varieties. in addition, estimates of the heritability of characters helps in selecting suitable breeding methods and predicting genetic gains of the traits. to determine general and specific combining abilities and gene effects of agronomic characters, five cms lines and four restorer lines...

Competition regulation in taekwondo has experienced several changes during the last few years, for example, kicks to the head score more points than kicks to the chest. In addition, some external factors such as the height of target and execution distance seem to affect the kick performance. The aim of this study was to analyse selected biomechanical parameters (impact force, reaction time, and...

OBJECTIVE To assess the somatic growth of preterm newborns through growth curves during the first 12 weeks of life. METHOD A longitudinal and prospective study was carried out at two state operated maternity hospitals in the city of Belo Horizonte. Three hundred and forty preterm infants with birth weight less than 2,500 g were weekly evaluated in terms of body weight, head circumference, and...

Introduction In recent years, thermal actuated flying height control has been implemented in Hard Disk Drives (HDD) to reduce the effect of flying height variations due to manufacturing tolerances or write current introduced pole tip protrusion (Fig. 1). A stable low flying height is necessary to achieve low bit error rates (BER) [1]. Thermal flying height control is used in a “static manner” i...

Introduction: Cow’s milk protein allergy is the most common food allergy in many countries, with clinical importance in different aspects. Synbiotic, a combination of probiotics and prebiotics, could be effective in the management of this allergy through modulating the immune system and improving the nutritional status. Methods: In this randomized, controlled trial, 32 infants with cow’s milk a...
