E STRUS and ovulation in gilts have been successfully inhibited by daily injections of progesterone (Ulberg et al., 1951; Baker et al., 1954) and more recently by the inclusion of progestational compounds in the feed (Nellor, 1960; Dzuik and Baker, 1962). The successful use of orally active progestational agents to synchronize the estrous cycles of gilts without a subsequent reduction in fertil...

In recent years, investigating synchronization of business cycles among countries, after increasing integration of global economies, has been attracted more attention of policy makers and researchers. Perhaps an unknown origin of such similarities, as an open question, is the main reason of these interests. So, with regard to the mentioned question, the aim of this paper is to investigate some ...

Treatment with GnRH and PGF2 alpha is a practical method for controlling ovarian follicular and luteal functions and increasing the precision of estrus synchronization in cyclic and acyclic postpartum cows and heifers. This method reduces considerably the period of time needed for estrus detection; it synchronizes the estrous cycle of 70 to 80% of the cyclic cows to within a 4-d interval withou...

the aim of this study was to evaluate the defense cells changes of cervical mucous during follicular and luteal phases of estrus cycle in river buffalo. reproductive organs of the adult and apparently healthy female buffaloes were collected from the slaughterhouse. by visual investigation of both the ovaries for presence of corpus luteum and growing follicles, the luteal and follicular phase of...

Adenomatoid odontogenic tumor (AOT) is an uncommon, slow-growing, noninvasive mostly in the anterior maxilla with three well-recognized clinico-pathological variants: follicular, extra-follicular, and peripheral. Extra-follicular variant presents as a well-defined, unilocular, radiolucency between, above, or superimposed on roots of erupted tooth. A 19 years female reported chief complaint loos...

One of the basic tenets in recent international trade literature is about the effect of trade integration on business cycle synchronization (BCS) among trading countries. The objective of this paper is to explore the main determinants of business cycle synchronization, with emphasis on trade integration. To this end, we have specified two simultaneous regression equations which were estimated b...

In this study, we propose a secure communication scheme based on the synchronization of two identical fractional-order chaotic systems. The fractional-order derivative is in Caputo sense, and for synchronization, we use a robust sliding-mode control scheme. The designed sliding surface is taken simply due to using special technic for fractional-order systems. Also, unlike most manuscripts, the ...
