It has been estimated that one child in 500 to 750 live births is born with a cleft palate (Rood & Stool, 1981). A high incidence of middle ear pathology is known to be associated with this problem (Bluestone, 1971). It is generally accepted that this population suffers from Eustachian tube dysfunction which leads in turn to the development of middle ear effusions and conductive hearing loss. T...
the purpose of this study is to evaluate financial participation of farmers to reduce the adverse environmental effects of contaminated water by using contingent valuation approach and tobit model by heckman's two stage. to achieve the desired goal, 100 questionnaires collected by a random sampling from farmers of kashaf- rood basin in mashhad city in 2014. results showed that variables of age,...
Recent studies have shown poor performance of irrigation systems, which indicates the requirement for special attention to performance improvement. The first step for improving the performance of irrigation systems is evaluation of the present situation. Performance evaluation methodologies presented so far are either qualitative such as DA (Diagnostic Analysis), RA (Rapid Appraisal) and FA (Fr...
This paper mentions a method for the detection and correction of films damaged by tear. The method includes estimation of motion vectors between two frames in an image sequence, delineating the tear boundary and restoring the damaged frame using suitable missing data treatment. Thus loss of data along the tear boundary is also corrected. The paper also includes the comparison of performance of ...
This study is focused on developing an integrated optimization-simulation model to develop the operation policies for a multi-purpose reservoir. Objective function of the optimization model is considered to be a linear function of reliability, resiliency, and vulnerability of river-reservoir systems. Genetic Algorithm (GA) is used to solve the optimization model in which the coefficients of the...
Aphaniusisfahanensis is a new endemic killifish species that has been described in the Zayandeh River of the Isfahan basin in Iran. During a study on the biology of nine fish from this species, the parasite Diplostomumspathaceum was observed in the aqueous humor of the eye of a single individual. It was visible as a white mass with a diameter of 0.38 mm. This is the first report on the infectio...
In this study the impact of climate change on temperature, rainfall and river flows of the Zayandeh Rud basin under two climate change scenarios for two periods (2010-2039 and 2070-2099) are investigated. For the evaluation of future climate change impact on stream flow to Chadegan reservoir, the global circulation model (GCM) outputs of the HadCM3 model (monthly temperature and precipitation) ...
