Annual ground cherry (Physalis divaricata) is an invasive weed in farmlands located in western Iran, but there is little information on effective options for its management, particularly in corn. Greenhouse and field studies were conducted to evaluate the... see more

The present study was undertaken to evaluate the lethal toxicity and stress levels of commercial formulations of Ammonium Sulphate toward freshwater Mystus vittatus. The 96 h LC50 values, determined in a semi-static system by probit analysis was 500 mg/L ... see more

The research aimed to know the production of cellulose in tofu liquid waste, the effect of adding ammonium sulfate to the nata de soya, and the quality nata de soya produced from Tofu Liquid Waste. The parameters used are the determination of the thi... see more

The aim of this work is to study theoretically, by mathematical model development, the effect of particle size distribution on the performance of rotary dryer to dry ammonium sulphate fertilizer assuming plug flow with axial dispersion pattern (PFDA model... see more

Aqueous two-phase system (ATPS) is an efficient, cost effective, fast, simple and ecofriendly method for the recovery of biomolecules. In the present study, an ATPS composed of polyethylene glycol and ammonium sulphate (NH4)2SO4 was used for the partial p... see more

This research learns about fractionation of lipases activity from coconut endosperm by using ammonium sulphate of 0–15%; 15-30 %, 30–45 %, 45–60 %, 60–75 % and 75–90 %. The results showed that the fractions of 0–15% ; 30–45 %, 45–60 % and 60–75 % have lip... see more

This research aimed to determine the optimum amylase activity at the variations of temperature and pH, and the effectiveness of extractors.  The extraction of the enzyme can be done in two ways, with an organic solvent and inorganic salt. We have con... see more

Zirconia nanoparticles were prepared by the precipitation and ageing methods. The precipitation method was performed by adding ammonium solution to the aqueous solution of zirconium chloride at room temperature. The ageing method was performed by leaving ... see more
