- چکیده انگلیسی: Rapidly increasing population, high life-standards, technological advancement and increasing diversity of solid waste have made solid waste management as an important and urgent issue for most of the countries. In this study, we address the complexity of waste-to-energy (WtE) planning considering energy security and sustainability, as a treatment for solid waste, in the Azerbaijan region of Iran. Decision-making for energy planning has gotten manifold quantitative and qualitative confliction which makes it really difficult to rely on exact values for criteria. Fuzzy logic with linguistic terms is utilized to express the uncertainty in the values with respect to defined criteria that are given by experts. In the first phase, the best WtE technology is selected and then suitable installation site is chosen using fuzzy group Viekriterijumsko Kompromisno Rangiranje (VIKOR) and ELimination Et Choix Traduisant la REalité (ELECTRE) III, respectively. Fuzzy entropy method was developed to determine the weights of the evaluation criteria. A case study is done for Azerbaijan region of Iran. Plasma WtE technology was found the best alternative for WtE energy technology and Zanjan province ranked the best location for the establishment of the site. In the sensitivity analysis, plasma technology predominantly stayed the most appropriate technology through different cases of weights, each focused on a specific aspect of criteria. A linear assignment method is used in sensitivity analysis for the WtE technology selection.

- چکیده:
- چکیده انگلیسی: In the present study, the core-shell magnetic nanostructure of Fe3O4@SiO2@CeO2 was synthesized to investigate its use as an effective photocatalyst for methylene blue removal. The prepared samples were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and a vibrating sample magnetometer (VSM). The photocatalytic activity for the Fe3O4@SiO2@CeO2 core-shell magnetic nanostructure was investigated under visible light by determining the degradation rate of methylene blue for 50 min. At the end of the photocatalytic degradation process, the magnetic catalyst was recovered by an external magnetic field. The performance of the proposed catalyst for the degradation of methylene blue was improved with the optimization of the effective parameters such as the amount of catalyst, pH, and reaction time. Under optimum conditions, the efficiency of methylene blue removal with the proposed photocatalyst remains higher than 92 % after five times of use. The second pseudo-model was selected as the kinetic model to calculate catalytic degradation. The present results show that the Fe3O4@SiO2@CeO2 can be an efficient nanocatalyst for the photodegradation of dye pollutants.

- چکیده:
- چکیده انگلیسی: Water deficit is one of the limiting factors of plant productions in arid and semi-arid areas. Many adaptive strategies such as accumulation of osmotic adjustments, phenolic compounds and antioxidant enzymes activity have been developed in plants for dealing with drought stress. The use of microorganisms, including probiotic bacteria, is a type of soil management that is effective in reducing the effects of stress. This experiment aimed to determine the effects of some probiotic bacterial strains on proline, sugar, total phenolic compounds (TPC), phenylalanine ammonia lyase (PAL), photosynthesis pigments and antioxidant activities of cucumber plants under drought stress. A completely randomized design was applied with a factorial arrangement of two factors: irrigation levels and bacteria strains with three replications. The results showed that proline, sugar, TPC, PAL and enzymes activity in control and inoculated plants were increased by increasing drought stresses. By contrast photosynthesis pigments significantly decreased under stress. The use of bacterial strains alleviate the harmful effect of stresses by an accumulation of proline, TPC, sugar, PAL activity and enzyme activity. The results also showed that inoculated plants had higher antioxidant activity compared to control plants under drought. It was found that the use of probiotic bacteria is an effective strategy to enhanced drought stress tolerance in plants.
