this study was conducted to determine the best pollinizer for five selected pecan cultivars in southwest of iran at safiabad agricultural research center in 2014-2015. the cultivars included: 'gratex', '10j', 'wichita 6j', 'graking', 'choctaw' as pollinated cultivars (♀) and 'gratex', 'peruque', 'comanche 4m', &apos...

ii Dedication This research project could not be complete without a dedication to my mother, Janet Hamilton Mahan, who died in August, 1979, of metastatic breast cancer. Her death was not immediate, there was a long period during which she fought hard to survive and her cancer went into remission. In retrospect, it appears that a number of stressful circumstances subsequently entered her life, ...

theory proposes that aggregates of several ribosomes, variously called polyribosomes (47), polysomes (47), or ergosomes (48), rather than single ribosomes, are the functional units of protein synthesis. Supporting evidence has come from amino acid incorporation studies in several laboratories using the following systems : (a) bacteria after infection with phage (42) or after lysis and the addit...

D iabetes is a clinically and genetically heterogeneous group of metabolic disorders manifested by abnormally high levels of glucose in the blood. This hyperglyce-mia results from either a deficiency of insulin secretion caused by pancreatic β-cell dysfunction or resistance to the action of insulin in liver and muscles, or both (1). Periodontal disease is one of the most common chronic inflam-m...

The purpose of this investigation was to examine the relationship between dental health and metabolic control in insulin-dependent diabetic children. Thirty diabetic children and adolescents (ages 4-19 years) were matched by age, sex, and race to 30 healthy children. Metabolic control was determined for each diabetic child by percentage of glycosylated hemoglobin, HbAI; 14 children were judged ...

Non-equilibrium Coulomb effects in resonant tunnelling through deep impurity states are analyzed. It is shown that Coulomb vertex corrections to the tunnelling transfer amplitude lead to power law singularity in current-voltage characteristics. Localized states of individual impurity atoms and interacting impurity clusters can play the key role in tunnelling processes in small size junctions an...

Cotton (Gossypium hirsutum L.) seedlings are considered to be sensitive to temperature stress. The exposure of plants to high and low temperatures can result in the production of reactive oxygen species that contribute to diminished plant performance. Plants have mechanisms that metabolize oxidants into less harmful chemicals, and enhancement of antioxidant metabolism has been shown to be benef...
