Aim of study: Quercus variabilis is a sclerophyllous oak with strong resprouting capabilities and whose regeneration facilitated by the development stump shoots following disturbance. During secondary forest regeneration, fine roots are important organs relative to changes in stand characteristics. Here, we aimed provide novel insights into chemical composition variations seasonality root order...

We have examined the ribosomal structural proteins isolated from vegetatively growing Tetrahymena pyriformis and from cells that had been starved of all nutrients for 24 h. Reproducible, nonartifactual differences in protein complement, primarily associated with the large ribosomal subunit, were found. The kinetics of change in ribosomal protein complement were followed both in refed and in new...

Quercus seedlings have hypogeal cotyledons and tap roots, both of which act as storage organs. The importance of the storage function in the two organs may change as the seedling develops. Therefore, changes in carbohydrate reserves in cotyledons and roots of Q. crispula grown under 40 % and 3 % of full light from shoot emergence to the completion of the first leaf flush were monitored. In addi...

background and objectives: medical errors and adverse events have recently turned into one of the predominant concerns of health-policy makers and health services providers. promoting safety culture is fundamental to sustainable safety improvement in healthcare settings. the purpose of this study was to examine the effect of training on nurses’ attitudes towards safety culture.   methods: a cro...

introduction: patient safety culture is an important part of improvement in the safety of health care. knowing its present status is required for development of safety culture. the present study aimed to evaluate the current status of patient safety culture in hospitals of three central provinces of iran. method: the present cross-sectional study was performed in teaching hospitals of tehran, a...

This paper has reported on the electrical and nonstructural of polymer-based materials in corporation NiO (Nickel oxide) in concentrations of 0.2%, 0.4% and 0.8% by weight of PVA (polyvinyl alcohol) polymer. Nanocrystallites phases and properties were characterized with using X-ray diffraction (XRD), Fourier transfer infrared radiation (FTIR),Energy distribution X-ray(EDX) techniques and X-Map ...
