Ammonium perrhenate is widely used in alloy manufacturing, powder processing, the catalytic industry, and other fields.Recrystallization can improve the specific surface area Health of ammonium perrhenate, reduce its particle size, and improve its particle size distribution uniformity.Therefore, recrystallized ammonium perrhenate can obtain better
Blade icing caused by low-temperature environments results in the degradation of wind turbine power performance.As there is no obvious influence on the performance of wind turbines in the early stage of blade icing, it is difficult to detect the early icing state, so there will be inaccurate labels in the process of data collection.To address these
Abstract The epithelial signaling pathways involved in damage and regeneration, and neoplastic transformation are known to be similar.We noted Crank Disk upregulation of argininosuccinate synthetase (ASS1) in hyperproliferative intestinal epithelium.Since ASS1 leads to de novo synthesis of arginine, an important amino acid for the growth of intesti
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a very rare and highly aggressive hematopoietic malignancy associated with a poor prognosis.It has been recognized to originate from precursors of plasmacytoid dendritic cells and has recently been established as a distinct entity.The most frequent clinical presentations are prominent skin les
Introduction The main producers of lentil are Canada, India, Nepal and China, respectively and Iran is the ninth producer in the world.The hand pulling is the usual method of lentil harvesting.Use of conventional combine because of short leg varieties, wide combine head in dry land and grain losses by cutter bar vibrations is impossible.So a mechan
