Methods A total of 75 female patients with AIS, 86 healthy agematched girls and 40 age-matched patients with CS due to excrescent hemivertebra were included into this study. Long-cassette standing coronal radiographs of the spine and pelvis were obtained from the subjects in fiston-clavicle position. The radiographic parameters were measured including length of spine (LOS), height of spine (HOS...
Background and Objective: The aim of the present study was to examine the relationship between characteristics of anthropometry, body fat percentage and amount of Sargent jump with swim time (100 m freestyle) in adolescent elite swimmers. Materials and Methods: This study was a descriptive therefore, 21 male swimmers aging 10-15 years old were evaluated in: height, weight, 8 length body, 5 w...
Introduction: Musculoskeletal growth is variable during adolescent period and reaches its maximum by 18 years, whereas hemopoietic parameters reach adult values by 15 years. After adolescence period, the blood parameters may vary with nutrition and built of the individual. The purpose of this study was to find out any correlation between anthropometric and hematological parameters after the ado...
to study the nature and magnitude of gene effects, heritability and number of effective factors for grain yield and some yield components in rice, six generations viz., p1, p2, f1, f2, bc1 and bc2 were prepared from the crosses of shapasand × irfaon-215 and irfaon-215 × saleh and grown in a randomized complete design with three replications. results of analysis of variance showed significant di...
Background: Problems and complications caused by inappropriate tables and chairs dimensions in changing the shape of children's body are important issues nowadays. The aim of this study was to evaluate anthropometric dimensions of the changes in elementary school students of Mazandaran province between 1992 and 2014. Methods: in two cross-sectional studies carried out between 1992 and 2014, an...
Background : Children are in their developing years and their bones and physical structure has not yet fully developed to a point of resiliency that can withstand stress, pressure, and a modicum of physical abuse and about 90% of students are carrying backpacks. Unsuitable backpacks cause shoulder pain, back pain, low back pain and skeletal malformation. Carrying backpacks heavier than 10% of...
When masking one-dimensional gratings, the strongest masking effect is achieved by using one-dimensional spatial noise, which can be regarded as a special case of two-dimensional noise where the noise check height is equal to the grating height. The extent of spatial integration in the human visual system is limited, however. Hence, our aim was to investigate whether the effective height of noi...
Six morphological traits of rice were evaluated in a 5 × 5 one-way diallel cross using a randomized complete block design corresponding with their F1 generations in 2007 at Iranian Rice Research Institute – Amol. Results from analysis of variance for traits of plant height, flag leaf angle, flag leaf length, flag leaf width, internode length and panicle length exhibited significant genetic diff...
