Improving Performance Criteria in the Water Resource Systems Based on Fuzzy Approach
Water Resources Management https://doi.org/10.1007/s11269-020-02739-6 Improving Performance Criteria in the Water Resource Systems Based on Fuzzy Approach Mohammad H. Golmohammadi1 & Hamid R. Safavi1 & Samuel Sandoval-Solis2 & Mahmood Fooladi1 Received: 28 July 2020 /Accepted: 6 December 2020/ # The Author(s), under exclusive licence to Springer Nature B.V. part of Springer Nature 2021 Abstract Reliability, resilience, and vulnerability (RRV) have been widely used as the performance criteria of a water supplyO system in the studies conducted over the last three decades. This study attempts to modify thenly traditional for method reading commonly applied to estimate these criteria using fuzzyDo logic therebyn the performance criteria of the points with the threshold and intermediate values are more accurately estimated. Traditional methods (RRV-Fixed) of estimating these criteria are based on the fixed threshold values to represent the functionality of a water supply system, using a binary system to identify the periods a system fails to supply the waterot demands. dowload The employment of this binary system may be taken into account as a weakness of the evaluating system, especially when water portion met is close to the threshold values. The present study develops a new method named RRV-Fuzzy, to ameliorate the weaknesses of the traditional RRV-Fixed estimating system.The method is designated as “Fuzzy Performance Criteria” built upon the traditional RRV formulae with improvements made to their structures using fuzzy membership functions. The efficiency of the proposed method is verified via implemen- tation on two case studies including a theoretical and a real-world water basin. -

Economic Impact Assessment of Water in the Zayandeh Rud Basin, Iran
Economic Impact Assessment of Water in the Zayandeh Rud Basin, Iran Rahman Khoshakhlagh University of Isfahan, Iran Comprehensive Assessment of Water Management in Agriculture Working Paper [Non-edited document] The main goal of this research is flush pointing major economic issues related to the economic impact assessment of water availability in the Zayandeh Rud basin in Iran. It goes without saying that economic assessments would start with considering water as a scarce commodity or a resource and then magnifying the intensity of scarcity along with variables or factors affecting the level of scarcity occurred or predicted to occur, for some determined span of time in the future. Having magnified the intensity of water scarcity the economics tools to deal with water scarcity is analyzed, such that goals defined i.e. food security and environmental concern along with growth are met. To show the intensity of water scarcity there are three main indices being used in the natural resource economics field namely: unit cost of providing water, market price or its shadow price, and rental value of water rights which include value paid to have access to the use of one cubic meter of water for duration of a year. However, in this research due to the lack of appropriate information on the rental value of water rights the other two indices are being used to evaluate the intensity of water scarcity in Zayandeh Rud. Before getting into the ways that can be used to measure economic scarcity of water we need to clarify the right economic meanings of the terms quantity of water demanded, water demand, quantity of water supplied, and water supplied. -

Methods: This study was conducted on neonates who were born from March 21, 2006 to March 20, 2011 and had undergone the congenital hypothyroidism (CH) screening program in counties affiliated to the Isfahan University of Medical Sciences. CH was diagnosed in 958 patients who treated with levothyroxine. The incidence rates of permanent and temporary congenital hypothyroidism in Isfahan province were calculated and their distribution was shown on the map. The space maps were drawn using the ArcGIS software version 9.3. Results: Based on the data obtained from the screening program, the average incidence of congenital hypothyroidism in the province during the period of 2006–2011 was 2.40 infants per 1000 live births (including both PCH and TCH). The most common occurrence was in Ardestan County (10:1000) and the lowest overall incidence was observed in the Fereydounshahr county (1.39:1000). The incidence of PCH in the counties of Ardestan and Golpayegan had the highest rate in all years of study; and the greatest number of TCH cases in the five years were observed in Nain, Natanz, Khansar and Chadegan counties. -

Control of Phlebotomine Sand Flies in Iran: a Review Article
J Arthropod-Borne Dis, December 2016, 10(4): 429–444 MR Yaghoobi-Ershadi: Control of Phlebotomine … Review Article Control of Phlebotomine Sand Flies in Iran: A Review Article Mohammad Reza Yaghoobi-Ershadi Department of Medical Entomology and Vector Control, School of Public Health, Tehran University of Medical Sciences, Tehran, Iran (Received 22 Aug 2016; accepted 17 Sep 2016) Abstract Leishmaniasis has long been known as a significant public health challenge in many parts of Iran. Phlebotomus pa- patasi and P. sergenti are the vectors of Zoonotic Cutaneous Leishmaniasis and Anthroponotic Cutaneous Leish- maniasis respectively, and 5 species of sand flies including P. kandelakii, P. neglectus, P. perfiliewi, P. keshishiani and P. alexandri are considered as probable vectors of Zoonotic visceral leishmaniasis. A literature search was per- formed of the relevant multiple databases from 1966 to 2013 to include studies on sand flies, vector control, leish- maniasis, Phlebotomus. Sand fly control in Iran began in 1966 by Iranian researchers, and long-term evaluation of its effects was completed in the study areas of the country. Herein, a review of vector control strategies in Iran to com- bat leishmaniasis including indoor residual spraying, application of chemicals in rodent burrows, impregnation of bed nets and curtains with insecticides, the use of insect repellents, impregnation of dog collars and the susceptibility of sand fly vectors to various insecticides has been summarized thus far. The investigation of the behavioral patterns of the adults of different sand fly species, introduction of biological insecticide agents, the use of insecticidal plants and other novel strategies for the control of sand fly populations have received much attention in the areas of studies, hence should be recommended and improved since they provide optimistic results. -
