Iranian Journal of Earth Sciences , 2012,
Abstract: The remains of the natural and human activities in some parts of the earth register as geopark. Actually, geopark is one or more geological phenomenon which is important from ecology, history, culture and archeological view. The aim of the geotourism description in an area and creating a geopark is trying to keep the earth's inheritance and locality the economic of the area. Iran with an old history, diversity of the environment and a lot of geological phenomenon has a great potential in creating geoparks. From this point of view, we can divide it into the five geotourism areas which are as follows: North, South, East, West and Central part of Iran. The Kashmar township is an area which is located in the south part of the Khorasan-e-Razavi province in the Northeast of Iran. This area because of the nearness into the desert, is hot and dry. The area is rich of mines, hot-water springs and geological landscapes. In this research, we tried to introduce some examples of the geotourism features in the study area such as faults, mines, hot-water springs, Bejestan playa, Asyab-e-Khooshab valley, Kavir-e-Lut salt desert, Bijvard entrance, Sar-e-Borj waterfall, Sir and Ahoo Bam caves and Natural glacier.

Abstract: Stratigraphic/palaeontological geosites of Stara Planina Mountain in east Serbia are well developed in the area of Serbian/Bulgarian state border, where with this occassion, three sections of exeptional geological and scientific interest are selected: Jelovica, Rosoma and Senokos. These geosites represent the important localities for study of Triassic and Jurassic terrigene-carbonate deposits, for which the scientific value from the domains of palaeontology, stratigraphy and sedimentology is widely known. The aim of this work is to represent the main scientific arguments for inventory and protection of detached transborder geological sites that are unique according to their composition and content.[Projekat Ministarstva nauke Republike Srbije, br. 176008]
Barremian-Aptian Dasycladalean algae, new and revisited from the Tirgan Formation in the Kopet Dagh, NE Iran
Taherpour Khalil Abad Morteza,Conrad Marc André,Aryaei Ali Asghar,Ashouri Ali Reza
Carnets de Géologie , 2010,
Abstract: Abundant, diversified algal assemblages comprising more than 25 species of Dasycladales are described from Barremian-Aptian limestone deposits of the Tirgan Formation in NE Iran. New species are described: one of them possibly belongs to a new endosporate genus, tentatively assigned the Triploporellaceae; two others, Clypeina ? sp. 1 and Rajkaella ? sp. 1, are left in open nomenclature. The widely distributed, locally abundant Montiella ? elitzae is revisited, because of the presence of a complete, exceptionally well preserved specimen. Yet to be demonstrated, the species is a junior synonym of Turkmenaria adducta Maslov, also originally described from the Kopet Dagh. Other species found in the Arkan section have already been reported from remote locations, primarily in Europe, in areas corresponding to the Northern and/or Southern Tethyan domains. Some of them are known only from the Hauterivian and/or the Barremian, excluding the Aptian, thus dating the lower part of the Arkan section as Barremian, but not excluding the Late Hauterivian.
New optically active and thermally stable poly(amide-imide)s containing N,N'-(Bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic)-bis-L-alanine and aromatic diamines: synthesis and characterization

Morteza Mellati,Mohammad Ali Fatemi,Khalil Motallebzadeh
English Language Teaching , 2013, DOI: 10.5539/elt.v6n4p126
Abstract: Teachers play different roles in multidimensional process of language teaching and their beliefs about language teaching might influence their practices. Donaghue (2003) stated that beliefs guide teachers in their practice. However, Argyris and Schon (1978) claimed that there is almost a discrepancy between teachers’ beliefs about language teaching and their practices in the classrooms. Therefore, the present study investigated the relationship between Iranian ELT instructors’ beliefs about language teaching and their real practices in classrooms. To achieve this goal, the researchers accidentally selected 369 Iranian ELT instructors and 512 Iranian students. To collect the required data, the researchers employed Teacher’s Beliefs Questionnaire (TBQ) to elicit instructors’ beliefs about language teaching and Students’ Satisfaction Questionnaire (SSQ) to elicit to what extent Iranian instructors applied their beliefs in their practices. Besides, to verify the results of questionnaires, the researchers interviewed nine instructors. The results revealed a positive significant relationship (p?0.05) between instructors’ beliefs about language teaching and their real practices in classrooms. The findings proposed some applicable implications that can be applied by policy makers and curriculum designers to provide facilities to support reflective teaching and to improve teacher education programs.

Agricultural Sciences (AS) , 2012, DOI: 10.4236/as.2012.32021
Abstract: Twenty mid side wool samples of crossbred sheep were collected and their characteristics were determined. Data analyzed by SAS software and Duncan’s multiple range tests was used for comparison of mean wool characteristics. Average fleece weight, yield, wool diameter, Fine fiber and staple length were: 431.59 ± 38.95 gr, 65.14%, 14.24 ± 0.67 μm, 48.67 ± 5.59, and 43.65 ± 4.15 mm respectively. Mean fleece weight was significantly affected (p < 0.05) by sex (female 259 gr and male 506.55) and age (248.25, 458.38 and 637.75 gr for 1, 2 and 3 yr old respectively). Mean wool diameter was significantly affected by sex (male 12.78 ± 0.49, female 15.33 ± 0.85 μm) and there was a significant difference (p < 0.05) between F1 and F2 generation 11.84 ± 0.58, 16.27 ± 0.72 μm respectively. There were effective differences among ages (12.55 ± 0.74, 14.47 ± 0.58 and 13.11 ± 0.64 μm for 1, 2 and 3 yr old respectively). Wool diameter of younger animals, males and F1 was so fine (12.55, 12.87 and 11.84 μm respectively). Staple length of F2 crosses was significantly longer than F1 crosses (p < 0.05). However wool diameter of F1 was significantly finer than F2, but length and down fiber percentage was less than second generation. As wild sheep shed his fiber in winter, the first filial crosses also shed their fibers from the end of winter to early spring. Shedding was seldom observed in F2 generations. It seems likely that wool from crossbred sheep could be used for those applications for which cashmere is suitable. This study indicates that, such crossbred sheep have a superfine wool and could be used in pure or blend for textile industry.

Open Journal of Animal Sciences (OJAS) , 2012, DOI: 10.4236/ojas.2012.21002
Abstract: Evaluation and grading of wool based on sex and age can help to improve economic value of wool. This study was conducted to investigate the wool production and fleece characteristics of Arabi sheep in Khuzestan province The right mid-side wool samples were taken from 90 Arabi sheep (1 - 4 years; 16 male and 74 female) by hand shearing. The staple length of shoulder, flank and rump were 13.18 ± 0.27, 13.31 ± 0.22 and 14.27 ± 0.25 cm, respectively. The greasy fleece weight, wool wax, vegetable matter, yield percentage, fiber diameter and its coefficient variation measures were 1.72 ± 0.06 Kg; 2.77% ± 0.12%; 0.54% ± 0.07%; 73.36% ± 0.68%; 30 ± 0.41 μm; 30.23% ± 0.3% respectively. Correspondingly, the medulated fibers, true wool fiber and Kemp fibers were 21.6% ± 1.9%, 76.1% ± 2.04% and 2.5% ± 0.57% respectively. Age and sex had a significant influence on staple lengths. Fleece weight (P < 0.01) and wool wax were (P < 0.05) affected by sex. There was no significant interaction between age and sex groups for fiber characteristics, but it was important for staple between body location (P < 0.05). There were a low considerable kemp and CV of wool diameter percentage on Arabi sheep in comparison with the other Iranian native sheep. The wide variation in fleece weight (0.8 - 3.9 kg); mean staple lengths (8.8 - 19.2 cm); medulated and kemp (0 - 84.04 and 0% - 30.22%); fiber diameter (24.9 - 37.43 μm) suggest potential for improvement of economical traits.

Thermodynamic Analysis of ZnO Crystal Growth from the Melt  [PDF]
Morteza Asadian
Journal of Crystallization Process and Technology (JCPT) , 2013, DOI: 10.4236/jcpt.2013.33012
Abstract: Recently, the efforts in solid-state materials include developing technologies capable of producing ZnO wafers in large dimensions and good quality based device applications. High quality bulk crystals are obtained by growing from high purity the melt. However, the thermochemical properties of ZnO (high melting point and high vapor pressure) make the growth of single crystals difficult. The thermodynamic calculations show that ZnO crystals can be grown from the melt if a suitable dynamic atmosphere composition is used. The oxygen requirement with increasing the temperature can be fulfilled by adding the NO-NO2 gases into the CO2 atmosphere. At ZnO melting point, the oxygen partial pressure of gas mixtures containing CO2-NO-CO-NO2 at Pt = 5 atm reaches to PO2 = 0.29 atm. According to this new thermodynamic result, it would be expected that ZnO crystal could be grown from the melt at lower total pressure comparing to pure CO2.
