        This paper presents an Algorithm to solve an urban waste collection problem bydelivering suitable route in each separate areas of Tehran in order to minimize the costof waste collection. We know the fuel consuming has a direct relation ship withdriving distances by collection vehicles, so, by minimize the cost of fuel consumingbecause waste collection consist of 50%-70% of totally collection expenses.Mathematical programming used to solve this problem base on integerprogramming with three variables and four limits.We propose a practical solution method which consists of three components: zoningAlgorithm, route generating Algorithm and combination Algorithm.Zoning Algorithm: a separated area divides in to small areas which each areaconsist of many big trash bins and surrounded between four streets, each points onborder could be considered as a start or end points.Route generating Algorithm: find the smallest routes between start and end points.Combination Algorithm: find the suitable neighborhood areas by consideration ofthe collection vehicles and capacities in each area. Until to minimize the traversedcompletely. Our topological limitations are: deadened streets, boulevards, traffic laws,such as one way streets in order to become closer in the real in the real word scale.The experimental results on real word problem, using data from 3 separate areas ofTehran, showed the superiority of the solution generated by the porposed intelligentAlgorithm to the solution generated by human experts.

        Background and Objective: Optimization of urban waste collection and transportation system has the largest part of waste management costs. Therefore, improving this system and reducing its operating costs as a necessity in urban waste management has always been considered. Method: Due to the high volatility, changes in the size of the waste, climate change and demographic and substructure tissue, the use of artificial neural network system (ANN) is a suitable method for predicting the production waste size, and on the other hand, for The optimization of the management system of these wastes is also used by the surface response method (RSM). Findings The results of this combined method show that the best combination of factors affecting urban waste transport system was proposed by RSM considering the largest loaded pack with about 26 workers, 10 pickups and 6 trucks. This combination is capable of carrying around 34836 tons of cargo at a cost of 596696000 Rials, which represents a high efficiency over actual values. Also, to predict load, the back propagation algorithm (BP) with 9 neurons in the hidden layer was selected as the best model with a predictive power of 99/19% in prediction of weight and 96/62% in cost prediction. Discussion and Conclusion: The results showed that using the combination of two methods of surface response as a statistical method and artificial neural network as a mathematical method, we can find suitable results for evaluation and optimization of waste collection and transportation system.

        Background and Objective: Declining water resources caused usage of recycled water that sometimes not purified well.  The growing population and consequently increasing water demand, along with a shortage of available freshwater resources have inevitably led to the use of unconventional water resources. Irrigation lands with urban wastewater requires quality and quantity control for achieving food security. Therefore, the present study was conducted to investigate the effects of irrigation with urban wastewater on the concentration of Nickel and Cadmium in soils and their effects on plant, root, shoot, and functional characteristics of wheat.Method:  Field sampling was carried out at random from a depth of 0 to 20 cm. Wheat samples were taken at harvest from a 1-meter by 1-meter area. A total of 20 samples for Cadmium metal and 20 samples of Nickel metal were taken.Findings: The results showed that the average concentration of Cadmium and Nickel was 10.6 and 49.43 kg, respectively, which resulted in an accumulation in various parts of the wheat plant. Increasing the concentration of Cadmium and Nickel in the soil increases the accumulation in the root, upper parts, and wheat seeds. Also, increasing the concentration of Cadmium and Nickel in the soil decreases the dry weight of the root, the shoot, and the weight of the thousand seed. However, there was no significant effect on two traits, number of grains per spike and number of spikes per square meter. The effect of Cadmium concentration was higher than that of Nickel.Discussion and Conclusion: Increasing 1 mg of soil Cadmium caused increasing, 0.81, 0.56, 0.6 mg Cadmium in root, upper parts and seed. For Nickel increasing the soil concentrations caused 0.29, 0.29, 0.11 mg in root, upper parts and seed. Manuscript profile

        Background and Purpose: Discharge of industrial wastewater to urban wastewater system is a way of its management, especially within the cities. If it is not done in proportion to the system’s capacity and under supervision, it may damage urban collection, transfer and treatment systems.  Material and Methodology: In this study, impacts of industrial discharges on urban wastewater facilities and the related standards and regulations in the selected countries are reviewed. Finding: The study shows Canada, Mexico, Argentina, Singapore, USA, and Australia and New Zealand consider 13, 10, 14, 22, 34 and 29 variables of industrial wastewater in their standards, respectively. Moreover, USA limits the flow ratio of industrial discharges to urban wastewater. In contrast, Iran has no standard for industrial discharges to urban wastewater facilities and there is just one guideline to regulate discharges in industrial towns, which consists eight variables. Moreover, the lack of assessment of urban wastewater network and treatment capacity to accept industrial discharges which, often due to deficiency of information and experience in this field, can disrupt sewage transmission and treatment processes. Discussion and Conclusion: As a result, setting national standard and guideline up to regulate industrial discharges to urban wastewater system, assessment of network and treatment plant capacity for accepting industrial discharges, and monitoring and supervision of these discharges to discover and prevent unauthorized discharges are critical measures to manage industrial wastewater especially within the cities in Iran.

        Objective: One of the factors causing colorectal cancer is infection with a specific strain of Escherichia coli (E.coli) that has a PKS genomic island with two clbB and clbN genes. One of the ways of human bacterial contamination is to consume vegetables irrigated with water contaminated with bacteria. These two genes cause the activation of the message transmission pathway and the DNA mutation and tumorigenesis by producing the toxin Bactin. The main aim of the present study is to investigate clbB and clbN genes in Escherichia coli isolated from vegetables irrigated with surface water and urban waste. Materials and methods: Vegetables irrigated with surface water, well and urban waste were collected from three regions of Tehran. Their E.coli bacteria were isolated and identified and confirmed. Then, PCR test was performed for clbB and clbN genes of all isolated E.coli bacteria. Findings: The obtained microbial and biochemical results confirmed the E.coli bacteria isolated from the investigated vegetables. The molecular results showed that the highest and lowest frequencies for the samples that simultaneously contained both studied genes were related to vegetables irrigated with urban waste and vegetables irrigated with well water (P≤0.05). This result was almost the same for the vegetables of all three studied regions. Conclusion: Considering the high frequency of E.coli bacteria isolated from vegetables irrigated with municipal waste and in order to prevent bacterial infection and consequently colorectal cancer, complete disinfection of vegetables and non-irrigation of vegetables in areas with waste are suggested. Keywords: E.coli, clbB, clbN, Vegetables, Urban waste, Surface water. Manuscript profile
