allometric growth pattern and body shape changes of the green terror (andinoacara rivulatus)(cichlidae) were studied using landmark-based geometric morphometric (gm) and traditional methods, from hatching up to 1266 hours post hatching (hph) under culture conditions. the left side of specimens were photographed using digital camera and morphometric characters, including total length, head lengt...

background and aim: it is well - known that sex hormones regulate bone metabolism. sex steroids increase osteoblasts activities and affect growth, remodeling and bone homeostasis. the aim of this study was to examine the effects of sex hormones deficiency on craniofacial growth in rats. methods & materials: fifty, thirty–day–old wistar rats comprised the sample in this experimental study. 25 ma...

a larger proportion of energy intake for reproduction and also low food availability maydecrease the growth rate of other organs during the late stage of the gonadal development. themain goal of this study is to examine the biological characteristics and organs growth pattern inclupeonella cultriventris during the late stages of gonad development. samples were collectedby capturing 300-350 kilk...

As fretting fatigue cracks are initiated at an early stage of life, the fretting fracture process is dominated by the stable growth of cracks. Hence the measurement of crack length is very important. This paper demonstrates the suitability of the DC potential drop technique for the measurement of fretting cracks. A calibration has been established for monitoring crack growth in BS L65 copper al...

in order to determine the age structure, growth, and length-weight relationship of the mudskipper, periophthalmus waltoni, from coastal mudflats of qeshm island, soroo and bandar-pol, in hormuzgan province, iran, we collected 192 individuals in february 2007. age was determined using the second pectoral radial bone and year class was based on length-frequency distributions. growth was descr...
