Agent -based model designed to evaluate the agile supply chain (case study: Tehran Science and Research High Education Institute)
One of the main challenges in organizations acting in a dynamic and complicated environment is doubtlessly agile supply chain based on which they have to be able to answer to customers quickly. But agile supply chain is influenced by different agents. Using the model based on agent, this study has tried to simulate the agile supply chain in a High Education Institute. There are three impressive elements are used in this model called as: smooth, offender and fault case those are also categorized in two groups impressive and impressible. There is a model is designed by using NETLOGO software which examines the impression and impressibility on each other. After executing the model at the case studied university at point of Time-769, the organization’s improvement will be possible in the best estate. All offender elements are reduced at this point.

The Criticism of Hadis in the Light of Quran in Al Forghan Interpretations
The main issue to recognize the true Hadis is to refer Quran in the criticism of Hadis. It is approved as a touchstone among the God’s messenger’s relatives as the first and the most important one in the interpretations at Al Forghan in the section of narration. The author tries to produce the Quran examples while there are some produce the Quran examples while there are some differences among the interpretations, this study tries to interpret at the differences.

Evaluation of precursors of N-nitrosamine in wistar rat fed high fat diet
The objective of this work was to investigate the possible formation of the heterocycyclic N-nitrosomorpholine upon administration of nitrite and morpholine and also the significance of high fat diet on the metabolism of the nitrosamine, using spectrophotometric, cell fractionation, centrifugation, thin layer chromatographic, ultraviolet irradiation and in vitro and in vivo methods. The possible endogenous formation of NMOR was detected in urine collected 24hours after a combined oral administration of 20mg nitrite and 40mg of morpholine/kg through the process of thin layer chromatography. The retention factor (Rf) 0.664 and the purple chromatogram observed in the test urine using a detector NEDSA spray correlated with that of the standard thereby indicating the in vivo formation of nitrosamine. Also an in vitro study confirmed the formation of nitrosomorpholine at pH 7.4 in an appropriate phosphate buffer. The increase nitrite level after incubation of the liver microsomal fraction for 30minutes, arising from exposure to ultra violet light irradiation, confirmed the formation of nitrosomorpholine. The histopathology result of rat liver treated with concurrent administration of morpholine and NaNO2 revealed heavy hemorrhage, inflammatory cells, fat deposition and general cytolysis which confirm the toxicity of nitrosomorpholine on the liver. It is concluded that the combined administration of nitrite and morpholine produced a nitrosamine whose metabolism to toxic species in the liver tissue is attributed to the biochemical and histopathologic lesions enhanced by a high fat diet.

Quantitative assessment of desertification with emphasis on geo-climatology
Desertification is considered as an important problem facing arid and semi-arid regions, as Iran. These processes are resulted either from human activities or adverse natural conditions. However, the combination of both is often applicable. The aim of this study is the identification of areas sensitive to desertification in the southeastern coast of Iran. In this study we used from IMDPA model for quantitative of this problem and we used from GIS for mapping of desertification. Three main benchmarks of desertification, including: soil, wind erosion and climate were considered. The results show that the weight of soil is 1.7 that it is the most effective benchmark in region. On the other hand with analysis of indicators we know that the most important is annual precipitation. After obtain each weigh of benchmarks we understand that the weight of desertification intensity (DS) in region is 1.61 and located in very high class. We know more that 1321.74 (Ha) is in medium class and 2639.30(Ha) of area is in very high class. After soli benchmark, wind erosion with 1.64 value and climate with 1.51 value are effective in desertification.

Molecular modeling of 1, 4-Phenylenediacetonitrile dye sensitizer for solar cells using quantum chemical calculations
The geometries, electronic structures, polarizabilities, and hyperpolarizabilities of organic dye sensitizer 1,4-Phenylenediacetonitrile was studied based on ab initio HF and Density Functional Theory (DFT) using the hybrid functional B3LYP. Ultraviolet-visible (UV-Vis) spectrum was investigated by Time Dependent DFT (TDDFT). Features of the electronic absorption spectrum in the visible and near-UV regions were assigned based on TDDFT calculations. The absorption bands are assigned to ???* transitions. Calculated results suggest that the three excited states with the lowest excited energies in 1,4-Phenylenediacetonitrile is due to photo induced electron transfer processes. The interfacial electron transfer between semiconductor TiO2 electrode and dye sensitizer 1,4-Phenylenediacetonitrile, is due to an electron injection process from excited dye to the semiconductor’s conduction band. The role of cyanine and methyl group in 1,4-Phenylenediacetonitrile in geometries, electronic structures, and spectral properties were analyzed.

Ferdowsi's Voice Echo in the Poetry of Behzad Kermanshahi Reflecting on His Patriotic Poems
Iranian contemporary poet, Behzad Kermanshahi is a poet devoted himself to Persian culture and literature and has had a special devotion to ancient Khorasani style, especially the peak of the epic poem, Ferdowsi Hakim. His works - which in Khorasani style are intermingled with modern language - contains profound human themes and meanings, which has given a beautiful tone to his poems. The most important of these themes can be summarized in patriotism, oppression, political commitment, loving Ahle- al-Bayt (AS), religious commitment, human-orientation, social and emotional commitment, hope and panic. Patriotism and love for the homeland has a special place in Kermanshahi’s poems. The poet's use of long and epic themes of the Shahnameh and its strong style and lofty language structure have led to the issue that in some poems, especially when writing a poem about patriotism and love for the homeland, Ferdowsi voice echo to be heard more than other issues.

Soil quality analyses under small farm holdings
The impact of soil quality indicators under small farm holding management practices was assessed to ascertain the status of soils and their potentials for sustainable agricultural development in Kaita, Mashi and Mai-adua Local Government Areas of Northern Katsina State, Nigeria. A total of 240 soil samples were collected for physical and chemical analyses. Perception of soil quality was investigated through the administration of 600 questionnaires. The Results indicated that pH value was optimum for crop production; PBS was low, but adequate and Ec within acceptable limits across the study area. SAR, ESP and OC contents vary within the Local Governments. It was concluded that farm management practices have effects on soil quality, and ultimately, crop yield.

Dynamics of an infinitesimal body with a decreasing mass in the restricted three body problem apart from the equilibrium points
The motion of an infinitesimal body with variable mass is studied. The equations of motion of the restricted three body problem with infinitesimal body of variable mass are introduced. The Jeans' law of mass change is applied. To tackle the dynamical problem, the Hamiltonian of the problem is formed with the time as independent variable. The solution of the equations of motion is formulated based on Lie series developments. Numerical representation of coordinates and momenta are given.

Measurement of radioactivity in soil samples in selected areas of Kibwezi district, Kenya
The averages concentrations of 238U, 232Th and 40K measured in the samples collected in this study are 130.6±38.7 BqKg-1, 137.9±39.7 BqKg-1 and 1120.1±245.2 BqKg-1 respectively. The absorbed dose rate in air at a height of 1m above the ground surface was estimated. The calculated radiation absorbed dose ranges from 95.4±3.2 nGyh-1 to 300.4±5.5nGyh-1 with an average of 193.2±44.5 nGyh-1 .The effective dose rates were calculated for human exposure to the gamma radiations and were found to be in the range (0.23±0.01- 0.74±0.02) mSv y-1, which is below the ICRP limit of 1 mSv y-1 for members of the general public.
