some small gabbro patches emplaced along the thrust fault with w-e trend in the vicinity of maien bolagh village at the ht/mp metapelites, a part of the central iran zone (near to sanandaj-sirjan zone). the coarse-grained dark gabbro samples consist of amphibole, clinopyroxene, plagioclase, minor quartz, titanite, and biotite. gabbros have high potassic calc-alkaline to shoshonitic affinity. th...

previous studies have shown that morphine administration could inhibit neural tube development in rat embryos and produce behavioral defects in human and animals. in the present study, the effects of maternal morphine consumption on embryonic neural plate development in wistar rats were investigated. methods: twenty-four female wistar rats (250-300 g) were crossed with males. after pregnancy, t...

Avian reoviruses (ARVs) are considered as an important cause of several diseases in poultry, particularlyarthritis and tenosynovitis. Tenosynovitis and arthritis, which are among the causes of chronic lameness inbreeder flocks, can result in reduced egg production and culling of breeder hens. In this study, the molecularcharacteristics of ARVs in some broiler breeder flocks were investigated in...

The flow field associated with the passage of the turbulent spot in a 3–D duct with streamline divergence under zero pressure gradients was investigated and displayed as contour plots of the velocity perturbation in plan and elevation view of the spot. It suggests that, streamline divergence has no strong effect on the internal structure of the spot and eddies and their propagation in the downs...

Abstract This paper attempts to re-investigate the catching-up (stochastic convergence) hypothesis among the selected 16 OECD countries applying the time series approach of convergence hypothesis with annual data over one century. To reach this aim, we propose a model which specifies a trend function, incorporating both types of structural breaks – that is, sharp breaks and smooth shifts usin...

various molecular techniques are available to make differences and to study the genetic divergences among species and populations, of which the most efficient ones are pcr-based markers. one of these methods, molecular fingerprinting, enables the distinction of closely related populations. issr-primers are universal primers that can be used for such studies. the utility of these primers was tes...

There are many information and divergence measures exist in the literature on information theory and statistics. The most famous among them are Kullback-Leibler [13] relative information and Jeffreys [12] Jdivergence. Sibson [17] Jensen-Shannon divergence has also found its applications in the literature. The author [20] studied a new divergence measures based on arithmetic and geometric means....

The present study represents a comprehensive molecular assessment of some family of freshwater fishes in Iran. We analyzed cytochrome oxidase I (COI) sequences for five genus of cypriniform fishes from Iran. The present investigation provides data on genetic structure of some species of Nemachilidae including Paraschistura bampurensis, Oxynoemacheilus kiabii and Turcinemacheilus saadii and Leuc...

introduction: in this study the effect of matricaria recutita extract on acute pain in the presence and absence of flumazenil (antagonist of benzodiazepine) and lesioned paragigantocellularis (pgi) nucleus was investigated. method: wistar male rats (250±20 g) were used. animals were grouped randomly into intact, sham and bilateral lesion of pgi nucleus. intact and lesioned animals, each divided...
