increasing the concentration of ammonia in water can cause fish death. this study was conducted to compare the performance of conditioned activated carbon and zeolite in ammonia (tan = total ammonia nitrogen) removal in a simulated transport of rainbow trout fry in 40-liter plastic bags. hence, responses of zeolite and conditioned activated carbon in ammonia (tan) removal at different concentra...

‎In this work, we find the differential transforms of the functions $tan$ and‎ ‎$sec$‎, ‎and then we applied this transform on a class of partial differential equations involving $tan$ and‎ ‎$sec$‎.

To clarify the potential involvement of plasmin(ogen) cascade proteins in the cell dissociation and subsequent invasion of pancreatic cancer cells, Western blot analysis, immunocytochemistry, immunohistochemistry, and in vitro invasion assay were performed in the cell lines or tissue of pancreatic cancer. The strong expression of plasmin(ogen), urokinase type plasminogen activator (uPA) and uPA...
