to study the effects of soil amendments on physical and hydraulic properties of a saline-sodic sandy clay loam soil, a field experiment was carried out as a complete block design with three replications. the treatments in this research consisted of control (b), 10 ton ha-1 gypsum (g), 10 ton ha-1 urban solid compost (c), three levels of vinyl alcohol acrylic acid (s1= 0.05%, s2= 0.1%, s3= 0.2%)...

citric acid has been reported to increase utilization efficiency of dietary phytate-bound phosphorus and protein. objective of this study was to determine the effects of citric acid on growth performance and nutrient retention of broiler chickens fed diets having two levels of non-phytate phosphorus and rice bran. giving a completely randomize design in 2 × 2 × 2 factorial arrangement, 144 broi...

cognitive teaching methods facilitate the acquisition of motor skills; among these methods, the combination of physical, observational and imagery exercises has been the focus of recent investigations. the aim of this study was to investigate the facilitative effect of the combination of physical, observational and imagery exercises on immediate and delay retention of badminton high serve. the ...

the present research examined the effect of different feedbacks such as blocked, random and specialized to the most difficult part of a task on acquisition and retention of badminton high service. at first, 10 expert badminton players performed 10 trial high service and 10 with probe technique to determine the most difficult part of the high service. the difference between the two scores define...

objective(s): auraptene (7-geranyloxycoumarin) (aur), from citrus species has shown anti-inflammatory, neuroprotective, and acetylcholinesterase (ache) and beta-secretase inhibitory effects. scopolamine is a nonselective muscarinic receptor antagonist which causes short-term memory impairments and is used for inducing animal model of alzheimer’s disease (ad). this research aimed to investigate ...

retention behavior of molecules mostly depends on their chemical structure. retention data of biologically active molecules could be an indirect relationship between their structure and biological or pharmacological activity, since the molecular structure affects their behavior in all pharmacokinetic stages. in the present paper, retention parameters (rm0) of biologically active 1,2-o-isopropyl...
