Abstract: 

Miocene siliciclastic sediments with 338 m thick are studied in the southern Neka of Northern Alborz flank. Detailed sedimentology study allows recognition four facies associations consist of delta plain, distributary channel, delta front AND pro-delta. Delta plain AND tidal flat include heterolithic shalesilt-sAND AND limestone with fenestral fabric. Distributary channel AND delta front associations consist of thin to thick channel shape sANDstone, which display coarsening-thickening upward cycles with pro-delta/offshore association. Ophiomorpha nodosa AND Thalassinoides in these sANDstones indicate a stressful condition such as sANDy mobile substrate, turbidity AND highly salinity fluctuation in the sedimentary environment. Shale-silty sediments of the pro-delta association with abundant framboidal AND chamber filling pyrite AND organic material display anoxic condition of the sedimentary substrate. Introducing Miocene hydrocarbon sediments in the neighboring region like Turkmenistan AND Russia AND sedimentary characteristics of the pro-delta/offshore shale of the studied succession allow us to introduce those as high potential cANDidate for hydrocarbon source.

Abstract: 

Detailed log facies studies of the Miocene Succession in the Rashidpur-04Well, Rashidpur Structure, Surma BASIN, were carried out by integrating wireline logs AND limited core sample data in order to reconstruct the paleoenvironment of the deposition. Based on the analysis of log motifs, grain sizes, sAND/shale ratios AND major changes in gamma ray log motifs, two major depositional sequences were identified in the Rashidpur-04 Well which consist of 17 para-sequence sets AND 22 para-sequences. Serrated bell, funnel, cylindrical, egg/bow AND linear log facies were identified in the study well. Lithology indicates that the whole well interval consists of alterations of sANDstone, siltstone, shale AND prodelta facies. Rashidpur Sequence-2 is thought to have been deposited in tidal flat to shallow marine conditions with prograding AND retrograding delta front conditions, whereas Rashidpur Sequence-1 is assumed to have been deposited under tidal channel, distributary channel, tidal flat, mudflat, marine inter-distributary bay to shallow AND deep marine conditions. Rashidpur Sequence-2 was deposited in comparatively deep water conditions while Rashidpur Sequence-1 was deposited in relatively shallow water conditions. From the present study it can be concluded that the Miocene Succession was coarsening upward in nature AND may have been deposited under a prograding DELTAIC SYSTEM.

Abstract: 

Excavations in Tepe Barveh were conducted with the aim to shed further light on the period of painted Bronze Age wares AND to refine the existing chronology for the Lesser Zab BASIN in the first half of the 3rd millennium BC. Thanks to its location in the upper valley of the Lesser Zab, the Barveh region served as a natural pathway for interaction between the Zagros foothills zones with the Rania AND Peshdar Plain in Sulaimaniyah province in Iraqi Kurdistan, AND the southern BASIN of Lake Urmia. By its overlapping Bronze Age sequence, the site offers a strong potential to fill the existing gap of information for the Early Bronze Age occupation in northwestern Iran. A foremost purpose of this paper is to situate Barveh within northwestern Iran, AND to explore intra- AND inter-regional interactions. The stratified occurrence of Painted Orange Ware (POW) is helpful to establish a sequence for the region AND to fill the existing lacuna. EBA sites in northwestern Iran beyond the Kura Araxes zone remain understudied, AND few sites offer deposits of considerable depth. The Early Bronze Age is generally associated with the burnished black pottery, while the orange pottery, a coeval AND equally important cultural hallmark, has attracted less attention AND remains a little known tradition. Hence, in light of the material culture excavated at Barveh, this paper seeks to gain an insight into the ways in which Tepe Barveh interacted with other regions dominated by the orange pottery culture. The ca. 8-meter deep EBA deposit at Barveh built up over c. 300 years AND represents this period of POW in an uninterrupted sequence, attesting to cultural continuity over an extended period of time. The culture shows parallels with EBA sites in the southern Urmia Lake BASIN AND in the Rania AND Peshdar plains in Iraqi Kurdistan

Abstract: 

current research is to critically analyze the discourse of world peace in the textbooks of the Iranian educational SYSTEM based on the theory of identification by L& M. For this purpose, the textbooks between the years 1357-1392 (primary period AND first period high school) have been analyzed. This article has been done with the combined method of analyzing the discourse of Fairclough, L &M AND focusing on the following questions: What was the status of the world peace discourse in the educational documents of this era? What subjects are these educational materials trying to create? What role have the dominant political discourses in this era played in shaping the identity of these subjects? The findings show that the discourse of world peace in educational books AND documents has been rejected due to the demarcation between Islamic AND non-Islamic, internal AND external. Power processes have tried to create militant AND vengeful subjects with a military identity. The factor of persuasion of the subjects is the axiomatization of the ideologies of the revolution with an Islamic nature. Also, the educational content by inducing specific defense ideologies has formed pacifist identities in all individual, interpersonal, social AND international dimensions.

Abstract: 

Leaf area index (LAI), a dimensionless biophysical variable is considered as one of the most important factors in characterizing canopy structure. It estimates the amount of foliage area per unit of ground area AND helps indirectly to assess biomass AND energy balance in an ecoSYSTEM. Remote sensing techniques established a strong correlation between the vegetation reflectance characteristics in red AND near infra-red bANDs AND LAI. Good number of image derived vegetation indices has been applied so far to estimate LAI successfully. In this paper correlation is established between field-collected LAI AND three soil adjusted vegetation indices, i.e., SAVI, MSAVI AND OSAVI derived from IRS-LISS-III data in DELTAIC ecoSYSTEM in Sagar IslAND of West BENGAL, India. LAI was estimated from OSAVI for the whole islAND as OSAVI yielded best result (R2= 0.92). Coarse resolution MODIS LAI (MOD 15A3) product was counter-validated with respect to the LISS-III derived LAI image following the upscale validation approach. Out of the six best-fit models applied, the logistic regression showed strong positive correspondence between the two products (R2 = 0.71). Uncertainty of the model was also assessed AND probable reasons were identified.

Abstract: 

سازمان بین المللی استاندارد از زمان تاسیس خود در سال 1942، استانداردهای بین المللی متعددی را با همکار ی متخصصان و کارشناسان برجسته جهان و همچنین کارشناسان موسسه های استاندارد کشورهای عضو این سازمان، تدوین و منتشر نموده است. هر کدام از استانداردهای انتشار یافته حیطه خاصی از عملیات و فعالیتها را پوشش داده و بر روی آن متمرکز می شود. مانند استانداردهای سیستم کیفیت، ایمنی و بهداشت حرفه ای و مدیریت محیط زیست. با وجود تشابه فراوان بین این سیستم ها، ادغام نیازمندیهای این سه سیستم بدون پیچیدگی به نظر می رسد؛ ولی این امر در عمل به سادگی میسر نیست. چرا که بایستی ابتدا برای هر سازمان فایده ها، مشکلات و مسایل حاشیه ای جهت ادغام در نظر گرفته شود. علاوه بر این، در نظر داشتن وجوه اشتراک و تفاو تها بین سیستم های مورد نظر نیز ضروری است. با این حال اگر نیازمندیهای سیستم مدیریتی مورد نظر به درستی در سازمان طرح ریزی و اجرا شده باشد و کارکنان سازمان نیز آگاهی و تعهد لازم را در ارتباط با نیازمندیهای آن داشته باشند، ادغام سیستم های مدیریتی به راحتی و بدون ایجاد اختلال در روند جاری فعالیتهای سازمان امکان پذیر خواهد بود. در این مقاله پس از بحث و توضیح پیرامون استانداردهای کیفیت، مدیریت محیط زیست و ایمنی و بهداشت حرفه ای، روشهای ادغام این سه سیستم و فواید ناشی از این ادغام عنوان خواهد شد.

Abstract: 

Introduction: Since flooding causes death AND economic damages, then it is important AND is one of the most complex AND destructive natural disaster that endangers human lives AND properties compared to any other natural disasters. This natural disaster almost hit most of countries AND each country depending on its policy deals with it differently. Uneven intensity AND temporal distribution of rainfall in various parts of Iran (which has arid AND semiarid climate) causes flash floods AND leads to too much economic damages. Detention BASINs can be used as one of the measures of flood control AND it detains, delays AND postpones the flood flow. …

Abstract: 

Persian language came in contact with BENGAL in 13th Century AND continued till 1837 when it was finally abolished as the official language of India. In this vast period of six hundred years, thousANDs of books were written in Persian, AND tens AND hundreds of poets composed their poems in this sweet language. During this period, Persian language AND literature reached the highest stage of its development, which yielded a huge collection of manuscripts, documents, miniature paintings AND other artifacts to BENGAL AND made her Sonar Bangla.The large-scale acquisition of manuscripts by Indians AND British officials in BENGAL gave birth to rich library collections that can sustain academic research in Persian Studies not only in BENGAL but internationally. The cataloguing of these collections has preserved the fruits of knowledge of Persian literature. The most important collections of Persian manuscripts are to be found at the Asiatic Society, Victoria Memorial, National Library AND Hazarduari Palace Library in Murshidabad etc. Though these collections have been documented to an extent by their cataloguers but many of them still need proper documentation, care AND conservation treatment. But their best fruition lies in their consumption for cultural studies as it is proverbially believed that the proof of pudding lies in its eating.

Abstract: 

Great Kavir BASIN is the largest inner BASIN in Iran that extended about 90000 km2.This BASIN is situated in the centre of Iran, to the south from Alborz mountain range AND elongated in the sub latitudinal trend AND its construction is asymmetric. The BASIN cover consists generally of complicated sequence of continental - marine Oligocene - Miocene molasses. According to drainage SYSTEMs conditions, molassoid cycles, alluvial, alluvial- DELTAIC AND lacustrine sediments, climate, morphological conditions AND metallogenic AND structural features, Great Kavir depression generally is favorable for exogenic AND surficial uranium deposits (vally-fill, flood plain, DELTAIC AND playa). Uranium occurrences that are known in the southern AND north eastern part of the margent Great Kavir BASIN, are Arosan, Irekan AND Mohammad Abad. Similar geological - structural conditions for uranium mineralization is possible in the margent of Great Kavir BASIN.
