the purpose of present paper was to examine the relationship between central bank independence and inflation rate in iran over 1960-2008. first, central bank independence has been accomplished through three indices including legal and real cbi indices and turnover rate of central bank governor index. then, augmented dickey-fuller test for model stationary of variables has been done by applying ...

Ranunculus L. with about 600 species is the largest genus in the Ranunculaceae. Problems in the taxonomy of the genus are due to high variability and polymorphism among different individuals and populations of certain species. Morphological characters of nectar scale have been considered as valuable taxonomical characters in some perennial species in some groups (Praemorsa, Grumosa, Rhizomatosa...

In order to determine genetic variability among 33 isolates of Fusarium semitectum, morpho- logical and molecular studies were carried out. Isolates from different paddy fields in the north of Iran were separated from each other in four morphotype groups. The isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextrose agar (P...

Understanding distribution of soil properties at the field scale is important for improving agricultural management practices and for assessing the effects of agriculture on environmental quality. Spatial variability within soil occurs naturally due to pedogenic factors as well as land use and management strategies. The variability of soil properties within fields is often described by classica...

Background: The purpose of this study was to compare electronic fetal heart rate monitoring (EFM) characteristics between Appropriate for Gestational Age (AGA ) and Small for Gestational Age (SGA) fetuses and to determine whether SGA fetuses have specific abnormalities. Materials and Methods: Among children born from Apr 2002 to Mar 2003 in Arash hospital, we identified 300 singleton infants b...

Introduction and purpose: Cardiac response to body core temperature variation measured with the very low-frequency parameter of heart rate variability. The aim of this study was to investigate the variability of very low frequency due to different temperatures of aerobic training in water and dry. Materials and methods: 40 academic active male were selected as research subjects. Then, all subje...

studies of rainfall variation generally focus on large areas. for example, in india, the area average monsoon rainfall series of the whole country or meteorological subdivisions are used. this would be of no use for local agriculture, particularly in places where rainfall is very high or very low, especially for crops like small cardamom and vanilla which are very sensitive to soil moisture and...
