This study was carried out in a completely randomized design 3×3×4 factorial arrangement in three periods of rearing in spring 1997. Density of 300 larvae was assigned for each oval tank with 0.1m2 surface area, 30cm deep, a volume of 20lit and 0.25 lit/min of water flow per minute at Shahid Rajaie fish breeding and culture center in Sari, north of Iran. The fries were divided into ...

Statistical tables including 50 and 95 percentile ranges are presented of the combined kidney weights compared with body weight, crown-rump length, and gestation age of foetuses and newborn children, and also a table of kidney weights related to post-natal age. The importance of relating kidney weight to more than one general body criterion in the perinatal period is illustrated.

Pediatric cardiopulmonary resuscitation drug therapy is based upon body weight, a statistic that often requires estimation. Using two current techniques of estimating body weight and the devised weight-estimating method (DWEM), the authors estimated the weights of 258 children. The DWEM, which is based on body habitus and height, was more accurate than other methods (P less than 0.01). Using he...

insulin-like growth factor-1 gene (igf1) is a biological candidate gene for investigation traits such as growth, body weight and muscles growth in different species. in this research eight pairs of white and wild quails were crossed reciprocally as a base population. a total of 34 quails were produced in first generation (f1) and 422 quails were generated by intercrossing the f1 population. bod...

Forty-eight mice maintained on a high fat diet supplement in addition to regular laboratory rodent chow responded differently in terms of body weight gain over a period of six weeks. Eleven mice gained weight that was comparable to body weights of mice given only chow for the same period of time while the others gained significantly higher body weights and became obese despite similar level of ...
