An experimental study has been carried out to characterize bubble formation, growth, and detachment mechanisms in a stagnant liquid column. Both bubble frequency and bubble detachment size were measured in different gas flow rates, injector diameters and orientations, submergence height, and liquid properties. Experiments were performed for air injection flow rate ranges between 200 mlph and 12...

many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

a pot experiment was carried out to determine the effect of foliage spraying of silicon (si) on growth and ornamental characteristics of calendula grown under salt stress and greenhouse conditions. a factorial experiment based on completely randomized design was conducted with 3 levels of si (0, 50 and 100 mg/l) and 3 levels of nacl (0, 100 and 200 mm) with 4 replications. at flowering stage, s...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

Sexually dimorphic growth hormone (GH) secretory pattern is important in the determination of gender-specific patterns of growth and metabolism in rats. Whether GH secretion in humans is also sexually dimorphic and the neuroendocrine mechanisms governing this potential difference are not fully established. We have compared pulsatile GH secretion profiles in young men and women in the baseline s...

An experiment was carried to evaluate the effects of gender and two dietary ionophores on growth performance and slaughter characteristics in Moghani sheep. A total of 30 Moghani lambs (15 males and 15 females) were distributed randomly into 30 individual cages. Each gender group consisted of 5 animals and fed with a basal diet with no supplement, the same basal diet plus 25 mg/kg monensin (MON...

The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...

  The aim of this research was to evaluate the effects of oral recombinant bovine somatotropin (RBS) 1% on growth performance of rainbow trout (Oncorhynchus mykiss). 600 rainbow trout weighing 46±1 grams were randomly allotted in two groups including: 1) the control group and 2) RBS treated group, each in three replicates. The fish were hand-fed with commercial pellets. The fish received 200g R...
