Background and Purpose: In recent years, the use of smart mobile devices due to easy access, portability, and also simpler user interface, compared to desktop computers has been met with unparalleled acceptance by Iranian users, managers, and sellers of goods. That's why application development for smart devices in Internet businesses has become essential. On the other hand, the location-awareness of such programs will make it smarter and provide targeted advertising and services to users.Methods: This study provides a model that first handles and categorizes information from some service centers and quickly exchanges data between smart media (such as a mobile, tablet) and data centers based upon online map services (Google Maps). Second, based on the components of location-based services (LBS), in order to provide effective advertising to users, the components of selecting the service center and advertising and navigation of the user to it were put on the agenda based on a loose coupling strategy.Findings: In order to have the features of recommendation, three criteria of desirability, namely the introduction of the final option based on the shortest route in the transportation network, or based on user scores or based on scores allocated by the relevant service unit class were considered. Finally, the "Location Finder" application was implemented under the Android operating system using the new technologies of the mobile and web-based spatial information system through the proposed model.Discussion and Conclusion: The results of the questionnaire were statistically analyzed using the frequency of the respondents and significantly showed the users' satisfaction with the program, with 55 percent rating it as a great choice for quality, and its compliance with the set goals so that it could fill part of the gap caused by the advertising software.

Background And Objective: In today's world, different approaches have been used to solve the problems of cities among them, we can mention livability and safe city. Various factors affect the viability of a place these include attendance, urban infrastructure and facilities, sense of belonging, efficiency and environment. It should also be noted that crime statistics (real) and fear of crime (perception) have a causal relationship with many health outcomes. The purpose of this article is to assess the interaction of security, social security and urban viability (in both objective and subjective dimensions) in Feyzabad neighborhood of Kermanshah. Security criteria were developed hierarchically as well as viability criteria in the form of relevant tables.Method: This research is applied in terms of descriptive-analytical method and correlation of factor analysis. With an error coefficient of 5%, the sample size of the statistical population is 395 people and the distribution of a random random questionnaire is simple. Finding: Research findings suggest that between social security and there is a significant positive relationship between objective and subjective urban livability, also, the rate of urban livability in Feyzabad neighborhood is moderately weak in terms of residents and the level of social security was assessed as poor.Discussion and Conclusion: The results show that the higher the indicators of livability in the neighborhood, there will be a greater sense of security, cultural and social planners and other related institutions are recommended in this regard take steps to promote a sense of security through careful and careful planning and by strengthening the livability indicators mentioned in the present study.

Tissues that have been formed in the past and throughout a long process have been gradually weakened with the growth urbanization and urban development. On the other hand, the impacts of the immense growth of urban populations have led to a dispersed growth and the emergence of the marginalization phenomenon, having resulted in its own distinct problems. Yet, it is well-agree that the urban areas are the best option for urban development due to their existing infrastructure and urban amenities. Accordingly, the present paper seeks to locate these lands in the trapped texture of the Avini neighborhood by compiling the criteria and indices from theoretical texts and practical experiences to identify the lands susceptible to endogenous development. In this regard, in order to reach a conceptual understanding and expert knowledge concerning the features of the lands susceptible to endogenous development, a questionnaire based on the theoretical framework was developed and completed by the urban planning experts On the one hand, the research method in this paper is, an F'ANP analytical method which is a combination of the functional analytical methods and the ANP; on the other hand, it is a secondary analysis of the location of the land susceptible to the development of an endogenous GIS. The findings of this study acknowledged that among all the factors affecting the identification of the lands susceptible to endogenous development in the Shahid Avini neighborhood, the performance criteria, and the accessibility and the related indicators attained the highest priority and prominence in locating these lands. Furthermore, a number of the parts related to the brownfields and the workshop located in the north and northeast areas of the neighborhood had a higher priority compared to the other parts to carry out the process of endogenous development with a weight between six and nine.

Abstract Background and Objective: Diazinon, an organophosphate pesticides and insecticides, that most widely used in agriculture. water-containing Diazinon can bring about serious environmental problems and also have immediate or even delayed impacts on people’s health. In this paper, the level of removal of diazinon from aqueous solution by Pseudomonas and Actinomycetes bacteria was investigated.Method: This study was performed on laboratory scale. The experiments were conducted separately with changes in effective factors such as pH, diazinon concentration, bacterial concentration, and process time. At first, Actinomycetes and Pseudomonas, which had the highest resistance to diazinon, were isolated and detected from the diazinon-contaminated soils. Then, the minimum inhibitory concentration (MIC) of diazinon was determined for each of the bacteria. The biological absorption and biological elimination capacity in these bacteria were examined.Findings: The results showed that both bacteria were able to remove diazinon. The most effective biological elimination of diazinon is related to Pseudomonas mass live mass at 60h , ph=7 and reaction temperature of 35° Celsius and concentration of one ml/L Diazinon and live weight 9000mg with a yield of 96,66%.The results showed that both bacteria were able to remove diazinon. The most effective biological elimination of diazinon was related to pseudomonas mass after 60 hours and pH = 7, temperature of 35 ℃ and the concentration of one mg/L of diazinon and the live mass of 9000 mg with a 96.66% efficiency.Discussion and Conclusion: This results showed that that both of two Pseudomonas and Actinomycetes bacteria a good candidates for eliminating of diazinon from aqueous solution. Pseudomonas has higher efficiency in absorption of diazinon. According to the conditions used, they can reduce the level of diazinon to an optimum level in the aquatic solutions

Backgrounds and research goals: The unbridled expansion of cities in recent dec-ades has led to the inefficiency of large parts of the structure and spatial organiza-tion of cities and the decline in climate comfort in them. Numerous policies have been proposed in the face of the problem of declining environmental quality and especially their climatic comfort, and various programs have been implemented in this regard. Therefore, this study tries to review the theoretical foundations in this area, finally appropriate solutions for the development of neighborhoods and neigh-borhood spaces in the climate of Hamadan has been proposed.Research method: The method of this research is that at first the effective compo-nents on climatic comfort and urban form were obtained by studying and examining the views of experts. To analyze the data, the simulation method and Ecotect Auto-desk software were studied in three traditional neighborhoods of Hamadan and ac-cording to the results, the factors.Findings: The results of the research show that Kababian neighborhood in the cold seasons of the year has more conditions to enjoy the sun in the morning and even-ing, but in the two neighborhoods of Haji and Aghajani Bey in the cold seasons should make more arrangements to enjoy The amount of sunlight used. Due to the fact that the amount of shading in these two neighborhoods in this season is more than the Kababian neighborhood and special measures are needed to create climatic conditions.Discussion and conclusion: In general, and according to the findings, one of the im-portant factors in optimizing traditional neighborhoods can be the use of centrifugal patterns in creating neighborhoods can increase the level of climate comfort in neighborhoods.

Background and goals: Urban spaces are the environment of human life and its activities. Crimes are committed as a destructive social phenomenon by man in these spaces. Including crimes in urban spaces that affect the quality of life and the security of citizens is the occurrence of urban crime. Factors such as urban planning, urban design, urban sprawl and social -Economics play an effective role in its occurrence or deterrence. Kianpars neighborhood can always face dangers like crime, depending on its location.Method: The aim of this paper is to study the lighting situation in reducing urban crime with an emphasis on CPTED approach in Kianpars neighborhood, Ahwaz, Which is done by descriptive-analytical method. In the descriptive section, statistics and information extracted from the Statistical Yearbook, the supreme court of the Khuzestan and police department of the study area were used. Finally, for analyzing the data, GIS and SPSS software have been used to analyze the relationship between the two factors of crime incidence and brightness levels Within the Kianpars range.Findings: The findings, which have been investigated in four areas, show that crimes committed in private space from 275 cases in Kianpars, 46 masses in private space in the first range: at the minimum of light, 43.5% , In the second range, 17.4%, and in the third range, 7.8% of the brightness, in the fourth range of brightness, with an unpredictable growth of 30.4%, which reflects the direct connection of light with reduced mass Ultimately, poor lighting conditions have resulted in reduced security and mass incidence and in general the lighting system was inefficient and in contradiction with CPTED principles. There is an inverse relationship between the occurrence of mass and light.Keywords: brightness, CPTED Approach, crime, Lighting, Security, Prevention, Design.

Factors such as urban planning, urban design, urban sprawl and social -Economics play an effective role in its occurrence or deterrence. Kianpars neighborhood can always face dangers like crime, depending on its location.Method: The aim of this paper is to study the lighting situation in reducing urban crime with an emphasis on CPTED approach in Kianpars neighborhood, Ahwaz, Which is done by descriptive-analytical method. In the descriptive section, statistics and information extracted from the Statistical Yearbook, the supreme court of the Khuzestan and police department of the study area were used. Finally, for analyzing the data, GIS and SPSS software have been used to analyze the relationship between the two factors of crime incidence and brightness levels Within the Kianpars range.Findings: The findings, which have been investigated in four areas, show that crimes committed in private space from 275 cases in Kianpars, 46 masses in private space in the first range: at the minimum of light, 43.5% , In the second range, 17.4%, and in the third range, 7.8% of the brightness, in the fourth range of brightness, with an unpredictable growth of 30.4%, which reflects the direct connection of light with reduced mass Ultimately, poor lighting conditions have resulted in reduced security and mass incidence and in general the lighting system was inefficient and in contradiction with CPTED principles. There is an inverse relationship between the occurrence of mass and light.Keywords: brightness, CPTED Approach, crime, Lighting, Security, Prevention, Design.","PeriodicalId":15762,"journal":{"name":"Journal of Environmental Science and Technology","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89310956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background and purpose: Thermal power plants play a major role in the production of air pollutants with significant consumption of fossil fuels. Sulfur oxides are among these pollutants. Regarding the necessity of reducing pollutants due to combustion of fuel in power plants of Iran this paper proposes a solution to select NOx reduction technology with investment approach in Iranian thermal power plants. Method:In this research, first with the extensive knowledge of research conducted in this field, the existing technologies in the world and also the most important criteria effective in their effectiveness have been identified and in the next step in order to adapt these criteria to Iran's conditions, from Fuzzy Delphi technique was used to finalize the criteria. In order to weigh the criteria and then rank the existing technologies, the new SECA ranking technique is used. Finding: . The results showed that IFGR technology, OFA, Flameless Combustion, LNB and FR(Fuel reburning) were the first to fifth priority of technology selection, respectively. Discussion and Conclusions: Together, these technology assessments will help create a more environmentally friendly and sustainable environment and make the ecological systems less vulnerable.

Background and Objectives: Increasing production rate, biogas volume and pressure, methane composition as an alternative for fossil fuels and reducing digestion time and the digestion process efficiency. The effect of adding a mixture of cow manure (CM) and digested to municipal organic solid waste (MOSW) in order to increase productivity of anaerobic digestion (AD) process is considered.Methods: Through three steps single MOSW, CM and digested mixing under mesophilic temperature were treated by laboratory scale Semi-Batch anaerobic digestion setup. Digested and CM mixing effect with MOSW were studied and evaluated by investigating of physical-chemistry properties, feed and digested elemental analysis, and also biogas pressure and volume measuring, AD time and biogas analysis. Findings: Adding mixture of digested and CM with MOSW increases feed dry part (organic and ash) and its carbon and nitrogen content. Transformation rate in MOSW co-digestion with digested and CM mixture (3rd step) compare to co-digestion of MOSW with digested (2rd step) and also conversion percent of mentioned quantities derived from 2rd step compare to single digestion of MOSW (1rd step) are increased. Biogas volume and pressure in base on feed mass unit and also biogas relative component during of shorter digestion time, in 3rd step compare to 2rd and also in 2rd step compare to 1rd are increased.Discussion and Conclusion: Digested and CM mixing with MOSW not only contributes in increasing the organic part of the feed, but also collaborates in inoculation in AD process and increases the methane generation. Existence of AD active microorganisms, especially methanogenic as well as enrichment of their growth and reproduction environment by tracer components and elements, accelerates the process, increases the biogas volume and pressure and also methane production efficiency as an energy producing part of the process.
