Various man-made agents like pesticides, industrial chemicals and some natural substances have the potential to alter hormonal pathways that regulate reproductive processes in certain species of wildlife. Until now, only a few investigations have been undertaken to determine the effects of these substances on reproductive capacities (fecundity and fertility) in exposed invertebrate aquatic spec...

The present study was carried out during two successive generations beside base generation, to improve egg mass (EM) through selection in developed Baheij chicken strain and to study correlated response of some production traits. The results showed that: 1Egg mass means for based generation (G0), first generation (G1) and second generation (G2) were 1741.29, 1904.52 and 2157.38g for S line and ...

in the egg shells when the eggs were studied in UV-light (Fig. 1). Control eggs did not fluoresce. The concentration of oxytetracycline in the egg shell, albumen, and yolk was measured by UV-absorption spectrofluorometry (Hayes and DuBuy, 1964). Oxytetracycline was deposited mainly in the shell (0.182 ± 0.028 iig./gm., mean ± SD), and albumen (0.190 ± 0.030 !*g./gm.) whereas the yolk contained ...

Background: This study was conducted to investigate the effects of natural and synthetic sources lycopene on performance, egg quality some blood characteristics Japanese quail layers. Methods: The 252 eight-week-old hens were randomly divided into seven treatments with three replication. first treatment fed basal diet (control). Second third given diets containing tomato fruit powder (TOM) at a...

Proof. First suppose that a ∼H b, so that a = bk for some k ∈ H, and let ah (with h ∈ H) be an artibrary element of aH. Then we have ah = bkh = b(kh) ∈ bH, hence aH ⊆ bH. The proof of bH ⊆ aH is similar. Conversely, suppose that aH = bH. Since a ∈ aH = bH we have a = bk for some k ∈ H. Then a−1b = k−1 ∈ H, hence a ∼H b. (d) Prove that the map g 7→ ag is a bijection from H to aH. Proof. Consider...

PURPOSE To analyze the anatomic consequences of selective amygdalohippocampectomy (AH) in patients with hippocampal sclerosis and to correlate the clinical outcome with the MR appearance. METHODS Seventeen patients were examined with clinical and neuropsychologic examination and cranial MR after AH (7 transcortical AH, 10 trans-Sylvian AH). The clinical and neuropsychologic outcomes after AH ...

Appreciated for their versatile nutritive value and functional properties, eggs are considered as an important item in human diet. Eggs are one of the most common foods available worldwide as they play an important role in human diet by providing humans with protein, lipids, minerals and vitamins in an adequate amount. Chicken breeds differ in physical and biochemical contents in terms of eggs ...

The syndrome of enhanced atrioventricular nodal (AVN) conduction has been defined arbitrarily by: AH interval during normal sinus rhythm (AH-NSR) less than or equal to 60 msec; shortest right atrial pacing cycle length (PCL) maintaining 1:1 AVN conduction (shortest PCL 1:1) less than or equal to 300 msec; and at the shortest PCL 1:1, an increase in the AH interval from AH-NSR (delta AH) less th...
