Two experiments were conducted to evaluate effects of strain [five in Experiment (Exp.) 1 and six in Exp. 2)] and age (29, 47, and 57 wk in Exp. 1 and 29, 41, and 52 wk in Exp. 2) of commercial broiler breeders on incubation time and chick weight. Highly significant differences in egg weight were found among strains in both Exp. After adjusting for effects of egg weight, significant effects of ...

Non-linear saturation kinetics can be described through a potency function, a trigonometric function, a logarithmic function, a hyperbolic function, or an exponential function. Saturable enzyme reaction kinetics can be alternatively formulated as a 1-exp function without the limitations of a steady-state assumption (d[C]/dt = 0, where C is the enzyme-substrate complex). The time-dependent subst...

This paper investigates the relation between immunity and hardness in exponential time. The idea that these concepts are related originated in computability theory where it led to Post’s program, and it has been continued successfully in complexity theory [9, 13, 20]. We study three notions of immunity for exponential time. An infinite set A is called • EXP-immune, if it does not contain an inf...

The present study was conducted on 20 adult albino rats divided into group I (n=10) and group II (n=1 0). Group I animals were: exp sed to cowdung smuke fOr 60 min twice a doy for a pf.'riod of 75 days whereas group II served as control. ECG of control rats was essentially similar to that of man. ST segment was absent, Q wave absent or rudimentary and the mean QRS axis + 45". Rats exposed to co...

Two experiments were conducted to determine if exposure of prepubertal heifers to supplemental lighting hastens the onset of puberty. In Exp. 1, 16 heifers were paired according to birth date (April 21 to July 4) and assigned randomly to exposure to either 18 h light/d (L) or natural photoperiods (N) from 22 wk of age until puberty. Twenty-two heifers in Exp. 2, born between February 27 and Mar...

Age-related vision impairment (presbyopia) is a consequence of a physiological process, involving gradual loss of accommodation potential. It affects most subjects above 45 years of age. Increasing life expectancy in developed countries has resulted in rising demand for correction of presbyopia (Adv Clin Exp Med 2010, 19, 3, 405–409).

Let fb k (n)g 1 n=0 be the Bell numbers of order k. It is proved that the sequence fb k (n)=n!g 1 n=0 is log-concave and the sequence fb k (n)g 1 n=0 is log-convex, or equivalently, the following inequalities hold for all n 0, 1 b k (n + 2)b k (n) b k (n + 1) 2 n + 2 n + 1 : Let f(n)g 1 n=0 be a sequence of positive numbers with (0) = 1. We show that if f(n)g 1 n=0 is log-convex, then (n)(m) (n...

The solubility of K2SO4 in water at 25°C was determined. Comparing the value ofthermodynamic solubility product constant, Ksp(th), (Ksp(th) = exp (-ΔGodiss RT) of the mentionedsalt to the value of concentration solubility product, Ksp(c) which is obtained from the observedsolubility, s/moL-1, Ksp(c) = 4s3, revealed a great difference. The difference can be satisfactorilyexplained using Debye- H...
