Despite the considerable expansion of our knowledge about the bovine reproductive cycle and the increasing possibilities to intervene herein, fertility in high yielding dairy herds has unremittingly been reported to decline since last decades. Since studies reporting about this fertility decrease originate from regions all over the globe, this situation seems to be widespread and universally ac...

member of the encyclopedia of the world of islam. many historians have researched about abbasides' rebellion, repeatedly, as one of the most important events of the early islam. however,there are no convincing replies for numerous questions about this subject yet. and there are still a lot for the researchers to find out about in this regard. in this article, by introducing one of the grea...

Pasteurella multocida is the causative agent of infectious diseases of economic importance such as fowl cholera, bovine hemorrhagic septicemia, and porcine atrophic rhinitis. However, knowledge of the molecular mechanisms and determinants that P. multocida requires for virulence and pathogenicity is still limited. To address this issue, we developed a genetic expression system, based on the in ...

The thermoelectric figure of merit (ZT) in narrow conduction bands of different material dimensionalities is investigated for different carrier scattering models. When the bandwidth is zero, the transport distribution function (TDF) is finite, not infinite as previously speculated by Mahan and Sofo [Proc. Natl. Acad. Sci. U.S.A. 93, 7436 (1996)], even though the carrier density of states goes t...

Temperature-dependent radiative recombination of free excitons involving one or two LO phonons in GaN is investigated in detail. It is found that both phonon sidebands possess asymmetric lineshapes and their energy spacings from the zero-phonon line strongly deviate from the characteristic energy of LO phonons as the temperature increases. Furthermore, the deviation rates of oneand two-phonon s...

With the goal of maximizing thermoelectric (TE) figure merit $ZT$, Mahan and Sofo [Proc. Natl. Acad. Sci. U.S.A. 93, 7436 (1996)] found that optimal transport distribution (TD) is a delta function. Materials, however, have TDs appear to always be finite non-diverging. Motivated by this observation, study focuses on deriving what bounded TD, which determined boxcar function for $ZT$ Heaviside po...
