In recent years, substantial efforts have been made to understand the implications of climate change on Antarctic krill, Euphausia superba , because their pivotal role in Southern Ocean food web and biogeochemical cycling. Winter is one least studied seasons Antarctica we limited understanding about strategies krill use survive winter. particular, data winter physiology condition juvenile are s...

The aim of the present study was to estimate the population parameters including length-weight relationship (LWR), condition factor (KF), relation condition factor (Kn), age, growth and mortality of Alburnus mossulensis in Azad dam and Komasi River in Kordestan Province, Iran. Of 522 specimens, the fork length, total length and weight of A. mossulensis ranged from 70 to 164, 75-175 mm, and 4.3 ...

The aim of this study was to investigate the adaptation of the cyanobacterium Fischerella sp. ISC 107to combined effects of carbon dioxide concentration, acidic and alkalinity. Axenic strain was incubated in BG0-11 medium. Carbon dioxide treatments were limited and relatively non-limited. Acidic (pH 5), neutral (pH7), and alkaline (pH 9) conditions were employed in each treatment. Survival, gro...

in this study, the effect of irrigation regimes and plant nutrition were evaluated as split plot arrangment based on randomized complete block design with three replications in 2010. treatments consisted of irrigation regimes at three levels: well-irrigation, irrigation disruption at vegetative growth stage, and irrigation disruption at reproductive growth stage as main plots and combination of...

the relationship between congenital heart disease (chd) and growth retardation is well documented. we investigated the growth condition of iranian children with several types of congenital heart disease (chd) and compared it with worldwide researches. growth condition was investigated in 469 patients with important chd aged from 1 month to 18 years. the patients were divided into two groups; in...

Background: Expansion and differentiation of stem cells relies on the soluble materials as well as the physical conditions of their microenvironment. Several methods have been studied in attempt to enhance the growth and differentiation rates of different adult stem cells extracted from different sources. Objectives: The purpose was to improve the three-dimensional (3D) culture condition of th...

The objective of this paper was to study the effects of two strains of isolated plant growth-promoting rhizobacteria (PGPR) on physiological and biochemical changes of wheat leaves under salinity conditions. The sterilized seeds were soaked in distilled water (control) and Nutrient Broth liquid medium of Enterobacter cloacae and Bacillus cereus (inoculated treatment) for 2 hours. After 10 days ...

It is known that zeolite, tested in animal feeds in recent years, has a positive effect on fish growth and many physiological parameters. For this purpose, rainbow trout (Oncorhynchus mykiss) was fed with feeds containing zeolite at different rates (1%, 3%, and 5%) for three months in the present study. Fish growth parameters (live weight gain, specific growth rate, feed conversion rate, condit...
