this experiment was conducted to evaluate the effects of different levels of calcium (ca) and phosphorus (p) on performance native hens of khorasan province. a total of 400 native hens from khorasan station were used in a completely randomized design (factorial experiment) with 8 treatments, 5 replicates and 10 hens in each replicate of  age 26 to 50 weeks. eight experimental diets based on cor...

Aluminum hydroxide is a compound with diverse crystalline structures, some of which demonstrate the ability to remove chemicals from aqueous solutions. In this research, aluminum hydroxide with the Bayerite structure was synthesized and used to remove Citric Acid (CA). This structure was not modified under the reaction conditions where CA ranged from 2 to 6 mg of CA in 20 mL of water, the t...

Background and objective: Nutrition and physical activity are two factors which affecting the control of body composition and cardiorespiratory fitness in the elderly population. Present study aimed to investigate the effects of continued training (CT) and high intensity interval training (HIIT) along with Citrus aurantium (Ca) on aerobic power and body composition of elderly rats.
