in order to study the effect of methanol on growth and yield of virginia tobacco varieties cocker 347, an experiment was carried out through a factorial experiment in randomized complete block design with 4 replications and 18 treatments. first treatment was spraying time which includes 3 levels, sprayed in the morning (8-10 hours) and noon (12-14 hours) and evening (17-19 hours) and the second...

An experiment was conducted that examined the effect of day-to-day variability of dietary energy on feed intake behavior. Three levels of average daily dietary ME composition (2,580, 2,814, and 3,009 kcal/kg) and three levels of day-to-day variability of ME (low, medium, and high) were assigned to nine groups of DeKalb-XL laying hens in a 3x3 factorial design. Each of the nine treatments contai...

the objective of this work was to develop bioadhesive topical gel of aceclofenac with the help of response-surface approach. experiments were performed according to a 3-level factorial design to evaluate the effects of two independent variables [amount of poloxamer 407 (pl-407 = x1) and hydroxypropylmethyl cellulose k100 m (hpmc = x2)] on the bioadhesive character of gel, rheological property o...

this experiment was carried out in the agricultural faculty of guilan university. the factorial experiment was performed based on a completely randomized design of three replications. the experimental factors comprised of: lillium cultivars, navona (asiatic) and fangio (la), four levels of calcium nitrate (0, 1, 1.5 and 2 mm) in combination with three levels of iba (500, 750 and 1000 ppm) . the...

Growing evidence suggests that parasite-infected prey is more vulnerable to predation. However, the mechanism underlying this phenomenon obscure. In small mammals, analgesia induced by environmental stressors a fundamental component of defensive repertoire, promoting responses. Thus, reduced may impair ability and increase their predation risk. This study aimed determine whether coccidia infect...
