Climate change is altering patterns of seed production worldwide with consequences for population recruitment and migration potential. For the many species that regenerate through synchronized, quasiperiodic reproductive events termed masting, these changes include decreases in synchrony interannual variation production. This breakdown occurrence masting features harms reproduction by decreasin...

to investigate the effects of different hormonal treatments on the oocyte maturation in wild- caught grey mullet ( mugil cephalus ), fish were subjected to 4 different hormonal treatments as follows: (a) a control group received 0.5 ml/kg b.w. physiological saline, (b) fish injected with 20 mg/kg carp pituitary extract (cpe) as a priming dose followed by 200 µg/kg sgnrha as resolving dose, (c) ...

introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

Menstruation is the end point of series events which begin in cerebral cortex and hypothalamus ends at uterus hypothalamic pituitary –ovarian uterine axis. Any break this axis creates Menstrual Problems. PCOS one such condition associated with abnormal gonadotropic secretion turn lead to menstrual irregularity acne hirsutism- Its prevalence ranging from 2.2% 26% age 18-45 years. In modern scien...

We show that if the intrinsic break energy of Gamma-Ray Bursts (GRBs) is determined by the product of more than three random variables the observed break energy distribution becomes almost lognormal including the redshift effect because of the central limit theorem. The excess from the lognormal distribution at the low break energy is possibly due to the high redshift GRBs. The same argument ma...

For corpus-based speech synthesis, large quantities of labeled speech are required. Manually labeling speech data is quite labor-intensive. Therefore, automatic speech labeling is highly desired. Prosodic break detection is one of the tasks for automatic speech labeling. In the paper, we propose an automatic break detection algorithm for mandarin Chinese speech. In this approach, we use energy ...

Temporal control of behavior was investigated within the framework of an internal clock model. Pigeons were exposed to signaled fixed-interval 30-s trials mixed with extended unreinforced (baseline) trials. On unreinforced break trials, the signal was interrupted for a period of time after trial onset. In Experiment 1, comparisons between the peak time obtained on baseline and on break trials p...

The endogenous catabolism of the cell protein of the L1210 mouse ascites tumor has been estimated from its in vitro break down to free amino acid after pulse labeling in vivowith leucine1-14C.Two general protein classes are distinguishable according to their breakdown: an unstable population representing onefifteenth of the cell protein and with an average half-life of several hours, and the st...

The chemical Langevin equation (CLE) is a popular simulation method to probe the stochastic dynamics of chemical systems. The CLE's main disadvantage is its break down in finite time due to the problem of evaluating square roots of negative quantities whenever the molecule numbers become sufficiently small. We show that this issue is not a numerical integration problem, rather in many systems i...
