ZnO thin films were successfully synthesized on a porous silicon (PS) substrate by chemical bathdeposition method. X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM),and photoluminescence (PL) analyses were carried out to investigate the effect of growth duration(3, 4, 5, and 6 h) on the optical and structural properties of the aligned ZnO nanorods. T...

Transition metal dichalcogenide (TMDC) materials are very important inelectronic and optical integrated circuits and their growth is of great importance in thisfield. In this paper we present growth and fabrication of MoS2 (Molibdan DiSulfide)thin films by chemical bath method (CBD). The CBD method of growth makes itpossible to simply grow large area scale of the thin la...

aim and background: schizophrenia is a chronic psychiatric disorder. the positive and negative symptoms are not only important in the prognosis of the disease but also affect the quality of life among the patients. therefore, the present survey aimed to determine the relationship between positive and negative symptoms and quality of life among schizophrenic patients in sina hospital in juneqan....

background health-related quality of life (hrqol) is used as a measure to valuate healthcare interventions and guide policy making. the euroqol eq-5d is a widely used generic preference-based instrument to measure health-related quality of life. objectives the objective of this study was to develop a value set of the eq-5d health states for an iranian population. patients and methods this study...

urban quality of life represents more than the private “living standards” and refers to all the elements of the conditions in which people live, that is, all their needs and requirements. in economic literature, urban quality of life is usually assessed through the standard revealed-preference approach, which defines a qol index as the monetary value of urban amenities. this paper proposes an i...

For chickens, arginine considered an essential amino acid due to the lack of urea cycle in birds. Arginine deficiency causes growth retardation, higher prevalence of disease due to the malfunction of immune system, and lower gastrointestinal capacity. However, higher levels of arginine in the diet improved growth performance, muscle hypertrophy, and meat quality. Arginine reduces carcass fat ac...

use poor quality resources of water and soil for food production in developing countries must be considered. therefore, three experiments were conduct in complete randomize design with four replications, to study effects of gradually application of different salinity levels (0, 10, 20, 30, 40, 50 and 60 ds.m-1) at different growth stages (planting and early seedling) and gradually application s...

the main challenge of developing countries, is achieving growth and development. review of economic growth literature shows that the quality of institutions and social infrastructure are important factors that influence the economic growth and development. also many analysts believe that between institutional factors, the rule of law is one of the most elements for appropriate system for invest...

background: women during the postpartum period experience many physiological, psychological, and social changes. quality of life (qol) is a sense of well-being and arises from satisfaction or dissatisfaction with various aspects of life including health, employment, socioeconomic state, psychological-emotional state, and family. moreover, qol is an important criteria for assessing healthcare sy...
