to determine the most important traits affecting root yield and sugar content in monogerm germplasm of sugar beet, 75 monogerm f1 hybrids were evaluated in three separate experments conducted in randomized complete block desing (rcb) with four replications at abdo–al–rasoul research farm, karaj in 2004. root yield, root length, root diameter, crown height, crown diameter, sugar content, α–amino...

background and aims. mineral trioxide aggregate and calcium hydroxide are considered the gold standard pulp-capping materials. recently, portland cement has been introduced with properties similar to those of mineral trioxide aggregate. histopathological effects of direct pulp capping using mineral trioxide aggregate and portland cements on dog dental pulp tissue were evaluated in the present s...

this study was conducted to compare different propagation methods and two cultivars (azarshar red, and kashan white) as a rcbd in factorial with four replications in shirvan in 2001. in azarshar red onion, high yield belonged to sets method that 30 percent more than seed sowing. in kashan white bulb cultivar, high yield was get from seedling cultivation and there were no significant differences...

South Africa is historically a nation of binaries. The most significant been the binary black and white. In this case, refers to all people African Asian descent or origin. Historical racism examined in light white fragility, supremacy normativity as ideologies that make it difficult for live together one united democratic upholding culture human rights. objective article propose dialogues on t...

change in transmitting time of impulses along axons is traditionally attributed to two parameters: the myelin formation and the diameter of neurite, both rising during the postnatal development. in the previous study, we showed that conduction velocity of the fibers projecting from the thalamus to the layer iv of the somatosensory (barrel) cortex increases as a function of age. however, the con...

polybrominated diphenyl ethers (pbde) are widely employed as flame retardants and constitutea group of emerging pollutants of high persistence. the degradation of different pbde commercial mixtures(penta-, octa- and deca-bde) by the white-rot fungus trametes versicolor under aerobic conditions wasstudied. this work demonstrates the capacity of t. versicolor to degrade three different pbde comme...

the aim of the present study was to investigate the light and electron microscopic structure of the tongue in white-eared bulbul (pycnonotus leucotis). six adult white-eared bulbul (3 males and 3 females) in shahrekord district were used in the investigation. samples of the apex, body and root of the tongue were prepared routinely for light and electron microscopic study. results showed that th...
