Calculation of the specific charge and specific drilling before a blasting operation plays a significant role in the design of a blasting pattern and the reduction of the final extraction cost of minerals. In this work, the information from the Sungun, Miduk and Chah-Firouzeh copper mines in Iran was assessed, and it was found that there was a significant relationship between the specific charg...
Background: Chronic myelogenous leukemia (CML) is a myeloproliferative disorder due to BCR-ABL1 translocation. Patients showing transformation into blast crisis (BC) have poorer treatment response and prognosis. Methods: A retrospective study was conducted in the department of Pathology, Maulana Azad Medical College, New Delhi, India, over a time period of 5 years (2014-2019) to evaluate the ...
Blast, caused by Magnaprthe grisea, is often an important fungal disease in the production of rice in temperate and tropical areas including Iran. To determine reaction of rice cultivars against blast disease, 40 rice genotypes from Iran and other sources from Asia were selected. Four blast isolates from different races were used to test all rice genotypes in different greenhouse tests. In bl...
In recent years, with the increasing number of terrorist attacks and explosions in structures, extensive studies have been carried out on the performance of structures and their reactions under blast load. Due to the importance of the pile in the load transfer of various structures such as wharves, oil platform and bridges it is essential to study the behavior of this member. In this research, ...
More and larger blast furnaces have been constructed for ironmaking across the world in recent years due to advantages of high productivity, energy efficiency low cost. Slag plays important role a furnace produce high-quality hot metal maintain smooth operations. Liquidus temperatures are essential information slag avoid formation solid phase during process tapping. The principal components iro...
The identification and consideration of various potential hazards significantly reduce the accidents in industrial locations where specific operations with explosive materials take place. purpose this study was to assess effects generated by external explosions produced near an experimental steel frame building model. novelty paper is combination results on site data from specialised databases ...

Rice cultivar Tarom Dilamani becauded a fragrance, flavor, cooking and marketing is a qualitative rice in Iran. This cultivar have high susceptibility against blast disease (Magnaporthe grisea). One of the important trouble producers of the Dilamani's rice cultivar is chemical control against blast disease and cause poisonous pollution of natural environment. The best manner in order to control...
