Various methods have been developed to manage municipal wastes in which landfills are the final destination apart from the used technologies. Given the sensitivity of this issue, identifing areas approriate for landfilling requires the application of comprehensive techniques. The objective of the present research is to select the most appropriate place for municipal wastes landfilling using geographical information systems, fuzzy analytic hierarchy process and fuzzy TOPSIS. Methods: Initially the effective factors in choosing landfill location was inquired from various institution and were standardized and analysed using geographical information systems. Then every criterion was weighted according to expert opinion and FAHP (Fuzzy Analytic Hierarchy Process). Then, FTOPSIS (Fuzzy Technique for Order Preference by Similarity to Ideal Solution) method was used to prioritize the options. Each method was programmed in MATLAB. Results: Thirty six suitable options were calculated through running the above mentioned methods. Then, two options that were located in the south east of the current landfilling (in Kulik) and Pakdasht city were selected as the best location for landfilling. Conclusion: Results showed that the selected landfills are located at a better position compared to the current one. And this integrated approach, showed a better performance than others due to taking into account the inexact nature of the phenomena both at weighting and ranking stages.}, keywords = {Solid waste,Sanitary Landfill,Fuzzy Analytic Hierarchy Process,Fuzzy TOPSIS,Geographic Information Systems,Pakdasht}, url = {https://jhad.kmu.ac.ir/article_91417.html}, eprint = {https://jhad.kmu.ac.ir/article_91417_f02370b475554341dfa6270ab57ffc38.pdf} } @article { author = {Azari, Ali and Gholami, Mitra and Mokhtari, Mahdi and Kakavandi, Babak and Ahmadi, Ehsan and Sattari Tabrizi, Mohammad Ali}, title = {Cr6+Removal by Activated Carbon Magnetized with Nona Zero Valent Iron from Aqueous Solutions: Kinetic, Isotherm and Thermodynamic Study}, journal = {Health and Development Journal}, volume = {3}, number = {1}, pages = {14-27}, year = {2014}, publisher = {Kerman University of Medical Sciences}, issn = {2783-2821}, eissn = {2783-2821}, doi = {}, abstract = {Background: Chromium is one of the most common pollutants that has been noticed in recent years due to its accumulation in human tissues and health risks. The aim of this study is to magnetize powdered activated carbonby Nano zero-valent iron (NZVI) particles and use it as the adsorbent for removal of Cr (VI) from aquatic solutions. Methods: In this study, reduction and co-precipitation methods were used for converting divalent iron into zero-valent iron and depositing zero-valent iron particles on powdered activated carbon in order to induct magnetic effect, respectively. Adsorbent characteristics were analyzed using SEM and XRD techniques. The pH, contact time, stirring rounds, adsorbent dose and the concentration of chromium was determined in optimal condition by Regression coefficient (R2 ). Then the isotherm, kinetic and thermodynamic equations of adsorption were investigated based on optimum conditions. Statical analysis was done by Design Expert software. Results: The highest removal efficiency was observed in pH=3, 60 minutes contact time and 0.5 g/L of adsorbent dose in the initial concentration of 4 mg/l chromium. Isotherm and kinetic studies also showed that adsorption process of chromium follows the Freundlich model (R2>0.991) and pseudo-second order model kinetics (R2>0.982) respectively. In evaluating the reaction thermodynamic, values of ∆Ho and ∆So was equal to 146.99 and -0.452 respectively, which illustrates reactions are endothermic and spontaneous. Conclusion: Powdered activated carbon modified by zero-valent iron has the ability to remove chromium effectively and could be separated from the sample by magnet simply due to its magnetic property.}, keywords = {Chromium(VI),Adsorption,Magnetic activated carbon,Nano zero valent iron}, url = {https://jhad.kmu.ac.ir/article_91418.html}, eprint = {https://jhad.kmu.ac.ir/article_91418_44c80982edf8ef1ab6a56776c8ff5054.pdf} } @article { author = {Shokouhi, Reza and Jafari, Seyed Javad and Joshani, Gholam Hossein and Taghavi, Mahmoud and Kashitarash Esfahani, Zahra}, title = {Study of Adsorption Equilibrium and Kinetics of direct blue 71 by activated red mud from aqueous solutions}, journal = {Health and Development Journal}, volume = {3}, number = {1}, pages = {28-37}, year = {2014}, publisher = {Kerman University of Medical Sciences}, issn = {2783-2821}, eissn = {2783-2821}, doi = {}, abstract = {Background: Some dyes are toxic and even carcinogenic and require separation and advanced treatment of textile effluents before being discharged into conventional systems. The objective of this study was to remove direct blue 71 dye from aqueous solutions using activated red mud. Methods: Red mud was activated by nitric acid and was used in the adsorption experiment. Direct blue 71 removal, using activated red mud was studied as a function of contact time, pH, and initial dye concentration. The adsorption isotherms were analyzed using the Langmuir and the Freundlich isotherms. Kinetics data were fitted with Pseudo-first-order and Pseudo-second-order models. Results: The adsorption rate increases with pH decrease, contact time increase, and increase initial dye concentrations. The Freundlich isotherm (R2=0.9737) was the best-fit adsorption isotherm model for the experiment. The adsorption data, followed a pseudo-second-order model (R2=0.9902).

Methods: This study included all welders working in one of the water heater making factories in Neyshabur who were 63 persons. Demographic information and respiratory complaints were collected by a questionnaire. Each worker's recent spirometry results were compared with his results from four years before using paired-samples t-test. Data analysis was performed using SPSS16 software. Results: The mean respiratory indices had all decreased after 4 years. The mean of FEV1 had decreased 0.12 L, ranging from 0.04 to 0.19, FVC had decreased 0.12 L, ranging from 0.03 to 0.2 and FEVI/FVC had decrease 77%, ranging from 0.11 to 1.31. This decrease was significant in all non-smoking welders, but not significant in smoking welders. Mucopurulent cough was the most common respiratory complaint among the welders.

Data gathering instruments were a questionnaire consisting of demographic variables and driving experience, Manchester Driving Behavior Questionnaire, personality characteristics assessment questionnaire (NEO PI-R) and perceived Locus of control questionnaire. Data were analyzed through SPSS16 software and using t-test, ANOVA and Pearson correlation test. Results: About 36% of drivers sometimes use safety belts and 3% of them never use it. Almost all participants (96.4%) reported some non-intentional violations. There was a significant moderate reverse correlation between attitudes about driving laws and both aspects of driving behaviors. Some of personality characteristics had significant reverse relationship with intentional violations. Relationship between perceived internal locus of control and driving violation was negative.

The adsorption process, as a simple and cost-effective process, has attracted great attention in pollutant removal. The aim of this research was kinetic and isotherm study of humic acid adsorption by silicon nanoparticles in water. Methods: This experimental study was conducted on a synthetic and then a real water sample collected from Alavian Dam in Maragheh city. The effects of pH, absorbent amount and time on the removal of humic acid were evaluated. In order to get a better insight into the process of adsorption, the adsorption kinetic and equilibrium isotherm and thermal energy were determined. Data analysis was performed through SPSS16 and using regression and Pearson coefficient of correlation. Results: The highest percentage of Humic acid adsorption was observed at pH=4, retention time of 10 minutes and absorbent amount of 0.25 g/L with removal efficiency of 88.4% and 86.7% for synthetic and real samples respectively. Meanwhile, the removal of humic acid followed Langmuir isotherm and its rate followed the second order kinetic model. Optimal capacity of adsorbent was 1.56 mg/g based on Langmuir model. The obtained RL (0.1) shows efficient silicon nanoparticles adsortion capacity in humic acid removal. Thermodynamic study showed that humic acid adsorption on silicon nanoparticle is a spontaneous and thermal process.
