This feelings ultimately would become an impeccable part of every district or region itself.These feelings between a certain district and a citizen has got roots in former experiences and characteristics of every individuals.This essay with clarification of effective factors on place attachment with a certain district which includes the “district entity,” “district affiliation,” and “social connection,” has embarked on comparison and measurement of these factors for certain districts in the city of Tehran. The method of research and study in this essay has been an analytical and dialectic process.This process has been concluded with dispersion of 475 application forms, field and district observation, and oral interview with teenagers between 12 to 16 from different districts of the City of Tehran, such as Elahieh in district 1, Narmak in district 8, Hashemi in district 10, and Yaftabad in district 17. To that end the Parametric F test (comparison of two variances), and also Tukey test (simple step multiple comparison procedure and statistical test) were utilized firstly to categorize the districts; and secondly in order to figure out which districts are similar, and which ones’ are different from each other.The F test outcome and result indicates that regarding the variances of “district entity,” “district affiliation,” and “place attachment” with respective results of 19.792, 9.174, and 11.153; conspicuous and visible differences are there among all compared districts.The observation done could be generalized with a margin of one percent trial and error respective to statistics.Regarding the variable of “social connection” with respective result of 0.616 there was no conspicuous and visible outcome among all compared livable districts through F test. However, the Tukey test indicates that regarding the place attachment, two districts of Yaftabad and Hashemi stand in one category, and the two districts of Narmak and Elahye in another category. Study of these two categories indicates that the Narmak and Elahiye teenagers and youngsters have more robust and social connection to their district than the teenagers and youngsters of Yaftabad and Hashemi.Finally, the district is compared with place attachment criteria and its factor is explained by Lambeda Quatation. - For the preparation of this essay; the Thesis Project of first Editor’s Ph.D. degree with the title of: “the social and environmental capabilities of the City of Tehran public areas in the eyes of teenagers,” was utilized. At the present time this essay with the help and guidance of the second, and the third editors of original Thesis Project is under progress. The entire current research is happening at the School of Art and Architecture at the University of Tarbiate Modares of the City of Tehran. - Ph.D Student in Urban Planning, Tarbiat Modares University.

Sodium dodecyl benzene sulfonate (SDBS) is one of the most important types of surfactants. The purpose of this study was to synthesize activated carbon (AC) from Iranian pine cones (Pinus eldarica) for the removal of sodium dodecylbenzene sulfonate (SDBS) from aqueous solution in batch systems. Method: The activated carbon samples were prepared using three activation agents including phosphoric acid, potassium carbonate and potassium hydroxide with different impregnation ratios. Pyrolysis process was performed in a ceramic furnace under a nitrogen gas flow rate of 100 ml/min with a heating rate of 8°C/min for 3 hours in 750 °C. Maximum surface area was obtained using synthesized activated carbon with H3PO4 in impregnation of 2:1 with 1580 m2/g. The synthesized activated carbon with three activating agents was used in the batch system to remove the SDBS from aqueous solution. Findings: The results showed that activated carbon produced by potassium carbonate with impregnation ratio of 0.75:1 has the highest absorption capacity of 97.56 mg/g. The experimental kinetic data were analyzed by pseudo-first-order, pseudo-second-order, and intraparticle diffusion models. The result indicated that pseudo-second-order with R2>0.982 provided a better description of adsorption data. Desorption experiments were carried out using different compounds. Sulfuric acid and ethanol showed the highest desorption rates of 65/67 and 40/03%, respectively. Manuscript profile -

The geographical spread of this plant is in the long sand dunes of Aran and Bidgol deserts. Biological properties, including free radical scavenging activity, total amount of phenolic compounds, antimicrobial properties and cytotoxic properties were investigated. Since the whole plant extract showed a high level of inhibition in the saltwater shrimp cell toxicity test (nearly 70 μg/liter), in order to obtain the effective components, solvent extraction using a decanter funnel was on the agenda. The three obtained components of hexane, ethyl acetate and water were analyzed separately. Also, by using a polystyrene divinylbenzene chromatography column, the effective component with higher inhibition ability was isolated. Among the effective components, except ethyl acetate, it had a relatively high inhibitory power, which was identified with the help of Hplc device.Findings: Comparing the antimicrobial power of Tribulus longipetalusViv with antibiotics, showed that this plant has good antimicrobial properties. Also, considering that LC50 was determined as 70 μg/ml. This value indicates the good cytotoxic power of Tribulus longipetalus Viv. Manuscript profile -

This reaction was catalyzed using ionic liquid, butyl-3-methylimidazolium hexafluorophosphate as a base catalyst with simple reaction condition and easy separation of products. The products were obtained in high to excellent yields and reaction time between 15 to 25 minutes. All products were identified by melting point, FT-IR and 1H NMR techniques. Manuscript profile -
