the study was undertaken to compare the efficacy of an estradiol-17β + cidr based protocol with the conventional ovsynch + cidr based protocol for synchrony of wave emergence and ovulation in murrah buffalos. in group i (n=25), on day 0 (beginning of experiment), buffaloes were administered a cidr device (1.38 g p4) and concurrently received 1.5 mg e-17β. on day 9, the cidr was removed and a pr...
the effect of lh and gnrh analogues on induction of ovulation in bactrian camel (camelus bactrianus)
ovarian follicle response and corpus luteum formation following induction of ovulation using gonadotropin-releasing hormone (gnrh) analogues and luteinizing hormone (lh) in bactrian camel were characterized. bactrian camels with a mature follicle (13-19.6 mm) received: 1) natural porcine lh (25 mg, iv, n = 4), 2) buserelin (20 μg, iv, n = 4) and 3) alarelin (25 μg, im, n = 4). daily ultrasonogr...
Three waves of behavior therapy with different objectives and methods have been published that in the formation of each of them, several factors have had impact. This study look at these factors and attention the current challenges of the third wave of behavioral therapy, points to the emergence of a fourth wave of behavioral therapy. Including the challenges of the third wave behavioral therap...

Although the discovery that follicles in bovine ovaries grow in a wave-like fashion has presented challenges for estrus synchronization and superovulation, recent protocols, designed to control follicular function have permitted fixed-time AI or fixed-time embryo transfer with high pregnancy rates, and the initiation of superstimulatory treatments at a self-appointed time, all without the neces...
The effects of tides on littoral marine habitats are so ubiquitous that shorelines are commonly described as 'intertidal', whereas waves are considered a secondary factor that simply modifies the intertidal habitat. However mean significant wave height exceeds tidal range at many locations worldwide. Here we construct a simple sinusoidal model of coastal water level based on both tidal range an...
Ovulation induction (OI) is a cornerstone of human assisted reproduction treatments (ART). Current OI protocols are based on the human follicular dynamics model known as propitious moment theory (PMT), by which follicles continuously grow from the primordial pool without any pattern, and follicular fate depend on the occurrence of a gonadotropin surge. Recently, a new paradigm of human follicul...
Emergence is a concept that is easy to exhibit, but very hard to formally handle. This paper is about cubic sand grains moving around on nicely packed columns in one dimension (the physical sandpile is two dimensional, but the support of sand columns is one dimensional). The Kadanoff Sandpile Model is a discrete dynamical system describing the evolution of a finite number of stacked grains —as ...
Regional innovations systems are a response to the emerging view in the 1990s that national innovation systems were not necessarily successful in addressing the challenge of competitiveness in period of globalisation. Indeed, with the emergence of clusters as a local innovation system much of the emphasis on competitive advantage in innovation was predicated on the existence of regional and loc...
