power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...

The present research was conducted to mitigate the environmental contamination and with the aim of evaluating the possible impacts of the application of sugarcane bagasse sewage sludge-based compost (BSC), vermicompost, and fish compost on different aspects of physiology, growth, and development of Lilliumlongiflorum var Ceb-Dazzle. The bulbs were planted in four different prepared soil mixture...

In recent years, special attention has been paid to the consumption of plant growth stimulants such as amino acids and humic acids along with micronutrients to adjust the effects of abnormal environmental conditions such as untimely cold or salinity and drought stress in grain production programs. In order to investigate the effect of growth enhancers on compensating for the lack of transport a...
