SASAKI, S. Growth Fraction and Cell Cycle Time of Gamma-rays Irradiated Mammalian Cells. Tohoku J. exp. Med., 1972, 108 (3), 225-237 Population kinetic analysis was made for growth fraction and median cell cycle time over 9 days after irradiation of a mouse mammary tumor cell population (FM3A) treated with 500 and 700 R of 60Co gamma-rays, where the growth fraction was estimated from labeling i...

this study was done on 4 and 5 years old great sturgeon cultured in brackish water ponds in bafgh salt water fisheries research station during one year. we examined somatic growth indices and effects of different diets on blood parameters and total length and weight. diet with constant protein (%40) and different energy levels (400,425,450,475 cal/100g) were fed to 74 pieces of great sturgeons ...

This paper uses two classes of multidimensional indices to measure countries’ evolution towards the achievement of United Nations’ Millennium Development Goals (MDGs). Our results suggest that improvements in the different MDGs tend to be uncorrelated among them and, on average, countries are largely offtrack in their way towards MDGs achievement. This evolution has been highly uneven across co...

Invasive pests, such as the cactus moth, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), have not reached equilibrium distributions and present unique opportunities to validate models by comparing predicted distributions with eventual realized geographic ranges. A CLIMEX model was developed for C. cactorum. Model validation was attempted at the global scale by comparing worldwide distrib...

use of the growth indices is a method to assessment of intercropping efficiency. in order to evaluation growth indices of soybean, sweet basil and borage in intercropping with different ratios, an experiment base on randomized complete block design was conducted with 9 treatments and 3 replications at north khorasan in 2011. treatments were consisted of the plants pure culture, replacement seri...

Competition indices are an attempt to quantify in a simple expression, the effects of neighboring plants on the growth of an individual tree. Many such indices have been proposed, and although few have reached operational use, this research has provided insights into tree growth and competition. Competition indices offer little utility for yield forecasting in "typical" stands. Few indices prov...
