A bench scale aerobic sequencing batch reactor (SBR) was evaluated in terms of its potential to treat synthetic dairy wastewater. The 2-l plexiglass bioreactor was supplied with oxygen via a fine bubble air diffuser, fed with synthetic dairy wastewater under various operational conditions. To analyze the process, three significant independent variables — influent chemical oxygen demand (COD), mixed liquor volatile suspended solids (MLVSS), and aeration time — were assessed. Three dependent process and quality parameters (as process responses) were also evaluated: total COD removal efficiency, sludge volume index (SVI) and final pH. The experiments were based on a central composite design (CCD) and analyzed using response surface methodology (RSM). The treatment was limited to the following concentration regimes: COD (1000, 3000 and 5000 mg/l), MLVSS (3000, 5000 and 7000 mg/l) and aeration time (2, 10 and 18 h). Maximum COD removal efficiency (of 96.5%) was obtained for an influent with the following characteristics: CODin: 3000 mg/l, MLVSS 5000 mg/l, and aeration time of 18 h. The study demonstrated the capability of aerobic SBRs for high COD removal from dairy industrial wastewater. Easy operation, low cost, and minimal sludge bulking condition were some of advantages of the SBR system as an option for biological treatment of medium-strength industrial wastewater. The present study provides valuable information about relationships between quality and process parameters for different values of operating variables.

The subject of this article is to study the factors and criteria of urban street desirability and citizens' expectations from them. The problem of research is the lack of accurate knowledge of the components of urban street utility in its various sequences. The theoretical proposition of the research is that the existence of quality in the physical, spatial, semantic-symbolic and activity-social components leads to vitality, memory, safety and flexibility as dimensions of citizens' expectations of the urban street. . The research method of the article includes descriptive-analytical and survey methods. Data collection method Interview is an open and semi-structured questionnaire. The statistical population of citizens is three sequences from Valiasr Street.
The results of the research show that vitality and memory play an important role in meeting the expectations of citizens from the city street. The two dimensions of flexibility and safety play a lesser role than these other two dimensions. The proximity of the importance of the four components leads to greater desirability. For the desirability of an urban street, the role of physical, spatial, semantic and activity components is very different according to the nature of the street sequence, but the effectiveness of all four components in creating desirability and creating a unique street character is very important. Physical and spatial components lead to greater vitality and safety, and semantic and activity components lead to greater memory and flexibility.

Molecular imprinting is a novel technique for preparing specific absorbents with selective sites for binding to the target molecule. Molecularly imprinted polymers, because of their high selectivity and stability, low cost and easy methods of preparation, have been widely employed in separation procedures. In this study, we evaluated the synthesized electrospun imprinted membrane (MIM) as a specific sorbent for herbicide mecoprop (MCPP). The films were prepared using methacrylic acid (MAA) as functional monomer and polyethylene terephthalate (PET) as a main part of polymeric solution and in the presence of dichloromethane (DCM) and Trifluoroacetic acid (TFA) as the solvents. The template was extracted through washing, results in the free specific memory sites within the films. Then, the synthesized electrospun imprinted membrane (MIM) was evaluated as a specific sorbent for herbicide mecoprop (MCPP). The results showed that the solution with 20% w/v of PET was the optimal solution for electrospinning process and at all different MCPP/MAA molar ratios (1:2, 1:4. 1:6 and 1:8), MIM had higher removal ability for template molecule (p<0.05) compared to NIM. The template/monomer ratio of 1:4 had the best binding amount. We also investigated the capability of MIM to be used as sorbent for pesticide 2,4-D, that is, the analogue of the main template molecule and diazinon, that is, the pesticide with different structure to the template. In addition, we used synthesized MIM and NIM films to extract MCPP analyte from environmental aqueous samples (bottled water and groundwater) and the results indicated successful performance of MIM compared to NIN.

Soil alkalinity and salinity are serious problems in arid and semi-arid regions, and therefore monitoring of soil pH and electrical conductivity (EC) is necessary in any region. The present study aimed to properly interpolate soil pH and EC as soil quality indices in a semi-arid mountainous area with annual precipitation of 342.4 mm. The study area is the Karimabad rangelands in Hamadan Province, western Iran. A total of 266 composite soil samples were collected from 0-25 cm soil depth in a systematic random design. Soil samples were processed for pH and EC analysis and then further used for interpolating based on the optimal interpolation method for the study area. The overall soil pH and EC ranged from 7.3-7.9 and 0.33-2.13 dS m^-1, respectively, presenting the slightly alkalinity and salinity problem in the region. The results showed the accuracy of spatial prediction of interpolation methods, particularly inverse distance weighting and radius basis function. However, based on root mean square error, the radius basis function was the most appropriate interpolation method to predict spatial distribution of soil pH and EC of topsoil in the study area. While salinity and alkalinity were low, still monitoring these soil indices is highly recommended to prevent the salinization and alkalization in the study area.

Introduction
Regional planning as an interesting and very important topic in the planning system of many countries around the world, is in the middle position of the planning hierarchy; It may sometimes be placed in a wrong position, which is often created under the pressure of powerful national and local elements of the planning system. In this way, its position is sometimes declining and sometimes growing. But what has drawn attention over time is the enduring nature and existential nature of this issue, which, like many other issues require this level of intervention. Therefore, it is believed that due to the increasing problems and challenges of today's society, there is a greater need for regional planning. Based on the studies done, balanced and sustainable development has been one of the main goals of the country for a long time. So that, with fluctuations, attention has been given to the category of "regional development" in the policies and development planning before and after the Islamic revolution, and in a sense, they have been among the components that the analysis of their effects on the face of the national system is very important at the level of micro-lawyers.
Methodology
The research method is descriptive-analytic, and library resources such as first-class sources, case-oriented articles and researches, and documents and documents available in the program and budget organization are used; Specifically, inferential methodology should be used to understand and explain the place of "regional planning and development" in the development programs before and after the revolution, and the possibility of comparison between them should be provided.
Research findings
What has attracted attention over time is the enduring nature and existential nature of this issue, which, like many other issues, requires this level of intervention. Therefore, it is believed that due to the increasing problems and challenges of today's society, there is a greater need for regional planning. Also, based on the field of regional perspective in development plans, it can be said that with regard to the general missions of land development and regional development in providing spatial justice in regions and creating equal and fair opportunities, access to resources, services and development achievements for all and in line with the implementation of the general policies of resistance economy and in order to creating a balance and benefiting the regions and provinces from facilities and improving their ability and flexibility against all kinds of environmental and external threats, competitive advantages must be created in the provinces and their relative advantages should be used optimally. Since, industrial investment in less developed areas should be promoted, the links between the border territories with the interior of the country should be strengthened, and in line with the national and trans-national role determined for the regions and provinces of the country, the role of medium and small cities should be strengthened, and also the metropolises should maintain their role, but decentralizing their national policy making is vital.
Conclusions
It can be seen that regional planning is a matter of interest and very important in the planning system of many countries around the world, since it is in the middle position in the planning hierarchy; It may sometimes be placed in a wrong position, which is often created under the pressure of powerful national and local elements of the planning system. In this way, its position is sometimes declining and sometimes growing. But what has drawn attention over time is the enduring nature and existential nature of this issue, which like many other issues require this level of intervention. Therefore, it is believed that due to the increasing problems and challenges of today's society, there is a greater need for regional planning. As can the current research findings shows, the failure of regional development planning and the division of spatial work with intensity and weaknesses in the programs before and after the revolution, causes the increase and widening of the areas of inequality between different regions. In general, fluctuations in the concept and function of regional planning in Iran is rooted in the country's structural obstacles both before and after the revolution. The ever-increasing centralization structure and the dominance of the planning procedure from top to bottom, departmental approach in planning, ambiguity in the legal status and executive guarantee of regional planning, lack of belief in planning and lack of planning culture and planability at different levels. The country's management, the lack of necessary and desirable platforms in order to attract the participation of the people and the private sector, the lack of organization in the regional Echelon, the non-compliance of plans with the existing realities, the non-compliance of upstream documents, the dominance of the abstract aspect on the plans and the like are among the main obstacles in the way of the development of regional planning in Iran

Idiomatic structures are of  the  forms which have been investigated  to argue in support of some theories  in Minimalist Program . In this regard the present study investigates the syntactic structure of Persian Idiomatic Expressions (PIE) in the frame work of minimalist approach. In this study a sample of 200 Persian idioms, selected randomly, have been studied to examine their flexibility in terms of their subjects, tenses and some other structures larger than Inflectional Phrase (IP).   The study supported  the idea that a phrase is formed by merging head ''X" and its complement ,and X-bar with its Specifier  to form X-bar and XP respectively. The analyses of the idioms shows that in the smallest form of idioms  a verb is merged with its complement  to  form a  "V-bar" and a V-bar is merged with a subject to form a VP. In this way the evidences from Persian support the idea of the Subject Internal Hypothesis.   The study also shows that idioms in Persian are fixed in bottom up way in forming Phrase Structure as in   V-bar , VP, IP(TP), CP respectively in clause structure level and even in larger ones.

The common pistachio psyllid, Agonoscena pistaciae Burckhardt & Lauterer (Hemiptera: Psyllidae), is a key pest of pistachio trees in Iran. Both psyllid nymphs and adults directly damage pistachio; they extract large quantities of sap from tree and produce honeydew and cause deformation of leaves resulting in great economic damage. Little is known about the intraspecific variation of common pistachio psyllid in regions with stressed conditions, such as areas under high levels of pesticide application. Therefore, this study using geometric morphometrics was designed to 1) evaluate morphological differences in wing shape in populations under different levels of pesticide application in Kerman province as the main pistachio producer in the world, and 2) search for a link between the morphological data and previously studied molecular data. The populations were collected from regions with high and low pesticide applications. The results showed that wing shape (P< 0.01) and size (P< 0.01) are different between populations exposed to different chemical control programs. Based on the results, narrower wing shape was found in psyllid population in stressed environment (population with extreme chemical control programs). In spite of allometric growth, significant shape differences still remain when the data are adjusted to constant size, which showed the important role of genetic changes in the observed morphological changes. Moreover, links between morphologic and previously studied molecular data were revealed. Based on the results, it appears that an evolutionary resistance process is developing, therefore insecticide resistance management programs, in the regions under investigation, is recommended.

Research subject: Osmosis membrane bioreactor is one of the best industrial wastewater treatment methods. The main advantage of using osmosis process is its operation at low hydraulic pressures which has a better performance in removing pollutants and low energy consumption than other methods                        
Research approach: In this research, Nano porous Titanium dioxide powder with a specific surface area and anatase wall was synthesized through a thermal process using cetyltrimethylammonium bromide (CTAB) as a surfactant directing agent and a pore-creating agent.Ultrafiltration nanocomposite membranes were made using modified titanium dioxide (TiO₂) (MT) and polysulfone (PSf) by phase the inversion method. The morphology and structure of the prepared membranes and nanoparticles were investigated using by atomic fourier transforms infrared spectroscopy(FESEM), X-ray diffraction (XRD) and transmission electron microscopy (TEM). In this research, bovine serum albumin (BSA) was used as simulated wastewater for the feed solution. The fabricated ultrafiltration membranes were tested in osmosis membrane bioreactor (OMBR) system due to lower energy and fouling. 0.6 % solution of poly (sodium 4-styrene sulfonate) was used as an osmotic solution. Comparative separation performance and antifouling properties of both nanocomposites in several analyzes such as water contact angle measurement, pure water flux and filtration of different concentrations of bovine serum albumin solution. BSA and fouling resistance have been investigated


Main results:  TThe results that Due to the addition of MT nanoparticles to the polymer matrix, the hydrophilicity and surface energy of the membrane increased, which led to the improvement of the membrane performance. The membrane containing 1% titanium oxide nanoparticles showed the best result. For example, for feeding with a concentration of 200 ppm, the water flux increased from 20 to 38.5 L/ m² h, and the percentage of returning lethal solution decreased from 19.6 to 30 g/ m² h. The flux recovery in this membrane was 96%, which indicates the antifouling property of the modified nanocomposite membrane.

The focus of this paper is on standard Markowitz mean–variance model and its traditional approach to solve portfolio selection problem (Quadratic Planning). For this goal we have applied a meta-heuristic method based on genetic algorithms (GA) in order to trace out the efficient frontier associated with the portfolio selection problem under cardinality and bounding constraints. These constraints ensure the investment in a given number of different assets and limit the amount of capital to be invested in each asset. We have presented some experimental results in two samples from Iranian stock market and overseas ones and compare the GA result with unconstrained quadratic results. Finally, we have found out which proposed GA can optimize portfolio selection problem under cardinality and bounded constrains

Steroids are one of the most important and abundant secondary metabolites of marine sponges. The aim of this study was to investigate the antibacterial properties of steroidal fractions derived from the Persian Gulf sponge Axinella sinoxea. Extraction was first done by Acetone and then the fractions were separated through column chromatography with silica gel. Identification of steroidal fractions were done by thin layer chromatography (TLC) and gas chromatography coupled with mass spectrometry (GC–MS). Then, antibacterial properties of steroids were identified and minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) were investigated by tubular dilution. Two types of steroids including Stigmasta-5,24(28)-dien-3-ol,(3β-24Z) and Ergosta-5,22-dien-3-ol,(3β,22E,24S) were determined. The extracted steroids showed different results regarding the growth inhibition and bactericidal effect on Gram negative (Escherichia coli, Klebsiella pneumoniae and Vibrio harveyi) and Gram positive (Micrococcus roseus and Staphylococcus aureus) bacteria at different experimental doses. In conclusion, promising results were found regarding the antimicrobial effects of the extracted steroids of the marine sponge from Larak island A. sinoxea. These findings reveal the necessity of more comprehensive investigations for the synthesis of pharmaceutical and antibiotic materials from the  bioactive compounds.
