The formation of atoll garnet in hornblende schists from the contact aureole of Mashhad granite,NE Iran, is discussed using textural and chemical data. These data suggest the possibility of incipientreplacement of pre-existing ...

While our knowledge of anuran embryonic and larval surface ciliation and their diversity ofciliation patterns are significant, very few references were noticed on embryonic ciliation in direct-developinganurans, such as ...

The late Eocene-early Oligocene Sarnowsar granitic rocks and many dacitic to rhyolitic dykesintruded in metamorphosed and metasomatized shale, sandstone, calcite and dolomite marbles andvolcaniclastic and pyroclastic rocks. ...

Viable cell concentration and luminescence activity of P. stutzeri P16 luxAB4 was measured byplate counting and luminometery in sterile and non-sterile soil adjusted to matric potential of -1500, -750 and-30 kPa. Results ...

The individual effects of cadmium concentrations (0, 0.005, 0.05and 0.5 mg. L-1) on the growth(cell number and chlorophyll content) and beta-carotene synthesis of two strains (Iranian and Australian) ofgreen algae D.salina ...

The genus Fusarium is a species rich genus. Different media are required to study themorphological characters and classify different species, a time consuming technique. In this study pecticzymograms were used to identify ...

A cytogenetic study was performed on 11 tetraploid cotton cultivars (Gossypium hirsutum L.)including the Oltan cultivar and its crossing progenies. The chromosome pairing and chiasma frequency, aswell as meiotic abnormalities ...

Meiotic study was performed in 11 Brassica napus cultivars considering chiasma frequency anddistribution, chromosome pairing, as well as the occurrence of B-chromosomes and their effects on chiasmafrequency. Such cytogenetic ...

Hormonally active agents are widespread in the environment and exist in the human diet. There isinsufficient knowledge regarding the influence of phytochemicals on the pathophysiology of the malereproductive system. Kiwi ...

The effects of drought stress and exogenous abscisic acid on the expression of ribulose-1, 5-bisphosphate carboxyIase/oxygenase activase (Rubisco activase) were examined in wheat (Triticum aestivumL.). In response to water ...

Twenty accessions of cultivated grass pea (Lathyrus sativus L.) and wild species of Lathyrus L.collected from western and southern regions of Iran were evaluated for their mitotic metaphase chromosomalcharacteristics. All ...

Lag is a general term applied to coarse grained (> 2 mm), hard, but partially weathered rockfragments, which are concentrated at the surface through attrition of finer materials. Based on morphology,mineralogy and the ...

For the first time, a spectrum of morphological abnormalities have been produced in developingmouse embryos (N=50), by injecting (IP) 75 and 100 mg/kg of maternal body weight of a new quinazolinonederivative, 4(3H)quinaz ...
