streamflow recession indicates the river network balance between revenue and losses of river. recession curve expreses the storage- output relationship for the catchment. the aim of this study was trend anaylysis, modeling of streamflow recession and uncertainty estimation in shahmokhtar station on the bashar river in kohgiluyeh and boyer ahmad province. based on the results of the mann-kendall...
background : the restriction in resources of health services renders the prioritization of the distribution of these resources necessary. the health care need index is used to investigate equality in distribution of health services. the main aim of the current study was to estimate this index for skin cancer in iran by involving the effect of adjacent regions. methods: the present study was a c...
Cypress (Cupressus sempervirens L. var. horizontalis) is one of the native conifers in Iran. It is found in Tange Soulak Forest Reserve of Kohgiluyeh and Boyer-Ahmad Province, Iran. An experiment in a completely randomized design with factorial 4×2×2 was performed to assess the factors affecting Cupressus sempervirens seed germination. Dieback, slope, and altitude were analyzed at four, two, an...
To design water constructs, such as spillways, canals and many other water structures one needs to estimate probable maximum precipitation (PMP). Since climate variability and spatial variations affect PMP estimation selection of proper statistical method, which provides better estimation is important. Based on general frequency equation, Hirschfield method has been proposed for this purpose, b...
Over the past few years, the syndrome of streptococcosis has been associated with outbreaks in rainbow trout (Oncorhynchus mykiss, Walbaum) and caused significant economic losses in the aquaculture industry in Iran. The main purpose of this work was molecular identification of some causative agents of streptococcosis in rainbow trout. A total of 520 samples were collected from the head kidney o...
The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
The logit regression model was used to measure the willingness to pay, and the parameters of this model were estimated based on maximum likelihood (probability) method. For this purpose, 377 double-duplex questionnaires were completed by random sampling method in Kohgiluyeh va Boyer Ahmad provinces. Based on the results, over 68.3% of respondents, they expressed their desire to participate in t...
Rangelands are the most important ecosystem for carbon sequestration. Knowledge of plant response to grazing is one of important requirements for rangeland management. Stocking rate is one of main factors in destruction of the vegetation cover in rangeland ecosystems. Livestock grazing has the potential to substantially alter carbon storage in grassland ecosystem. This study examined the effect...
Aims: Adherence to treatment is one of the most important concepts in the field of physical diseases, including hypertension. Many patients do not adhere to the treatment and ignore the doctor's instructions, which can cause many economic, physical and cultural problems for the individual, family and society. Many factors, including self-efficacy, self-regulation, and social support, are associ...
The purpose of this study was to investigate the effect of the flipped class approach on math learning of students in multi-grade classes. This research is a quasi-experimental design of pre-test-post-test-follow-up with a control group. After studying and designing educational work, 36 elementary school students studying in two multi-level schools in the academic year 1300-1400 in Kohgiluyeh a...
