In this study, in order to study the base temperature (minimum temperature for plant growth) at the degree of growth day (GDD), which is one of the important parameters in calculating the degree of growth day, first, the data required for the 2009-2017 statistical period of wheat production at the station Sararood was taken from the station. Then, after sorting and separating growth different s...

Low survival of newborn seahorses hindered studies on the early life stage. Many important aspects contributing to the survival of newborn seahorses remained unknown. More research on juvenile stage is necessary to optimize the culture protocols. Stocking density may or may not affect fish growth and behavior. Effect of stocking density on the growth and survival of seahorses in the early stage...

introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...

the control of the configuration of the nise nanostructural thin films with temperature

This experiment was carried out to examine the effect of temperature on egg incubation period, exogenous feeding onset, growth and survival of the zebra cichlid , Cichlasoma nigrofasciatum larvae with two replications. Experiment was conducted in four groups of brood stocks with Four temperatures with two replications 22-24 °C, 24-26 °C, 26-28 °C and 28-30 °C. After ovulation brood stocks were ...
