Development consists of growth and differentiation, which can be partially decoupled and can be affected by environmental factors to different extents. In amphibians, variation in the larval environment influences development and causes changes in post-metamorphic shape. We examined post-metamorphic consequences, both morphological and locomotory, of alterations in growth and development. We re...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
It is of significant value to reduce users’ communication cost to the lowest possible degree, especially in the mobile communication environment that is becoming more and more prevailing. Scientists have discovered that users’ communication cost can be effectively reduced by employing some more flexible data distribution algorithms for users’ data. In this Paper, a new algorithm is suggested to...
Several temperature-humidity indexes (THI) have been used to estimate the degree of thermal stress experienced by dairy cows. The present objectives were to develop equations using meteorological variables that predicted rectal temperature of lactating cows in a subtropical environment and compare the goodness of fit of these equations to those using 8 different THI. Rectal temperature was meas...
The oil in the pipelines must be heated to a certain temperature in some oil fields in north of China. Otherwise, the oil will freeze because of much paraffin mixed in it. A method to detect the direction of the pipeline underground accurately is described in the paper. The temperature of the pipelines can conduct to the surface of the soil and be detected by an uncooled focal plane arrays (UFP...
Changes in Climate parameters have been accelerated in the coming age, which can affect agricultural activities directly and indirectly. Temperature and precipitation are the most complex climatic factors. Spectral analysis is a scientific and efficient technique used to recognize and detect the hidden behaviors of these variables. In this research, in order to study and analyze the temperature...
