The average time of input water needs to recharge the groundwater basin and reach a catchment outlet, whether it follows vertical or horizontal flow direction, is known as mean residence (MRT). This study aims identify theory concepts estimation MRT in well using environmental isotope technique. For this purpose, spatiotemporal data oxygen-18 precipitation Erbil city were taken from Global Netw...

Background: Reports on the pharmacokinetics of marbofloxacin in birds are scarce, even when it is a useful tool in poultry production. OBJECTIVES: Determining marbofloxacin kinetic parameters in plasma and muscle arrangement after intravenous and oral administrations and establishing its withdrawal period. METHODS: Clinical healthy chickens (1.08±0.22‌ kg) were used as experimental subjects, fo...

Nanopore sensing is a label-free method for characterizing water-soluble molecules. The ability to accurately identify and characterize an analyte depends on the residence time of the molecule within the pore. It is shown here that when a Au25(SG)18 metallic cluster is bound to an α-hemolysin (αHL) nanopore, the mean residence time of polyethylene glycol (PEG) within the pore is increased by ov...
