A group of twenty-nine high school student-teachers were given a set of mathematical propositions focusing on shape-to-shape transformations. Their task was to determine through hands-on manipulation and use of dynamic software that each shape be transformed into an area equivalent rectangular region. This paper reports on a classroom-based research.
Thermostimulated Luminescence of GaS:Yb Crystals
Rahim Salim Madatov,Fargan Gabil Asadov,Elshan Gabil Asadov,Tural Gulu Naghiyev 한국물리학회 2019 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.74 No.5
The thermoluminescence of Yb-doped GaS upon UV irradiation has been studied in the course of linear heating. The observed thermostimulated emission bands are found to be complex and to consist of several strongly overlapping partial maxima. The activation energies, capture cross sections, frequency factors and concentrations of the trap levels responsible for these peaks are determined.
Layering the Internet-of-Things with Multicasting in Flow-Sensors for Internet-of-Services
Rahim Rahmani,Theo Kanter 보안공학연구지원센터 2015 International Journal of Multimedia and Ubiquitous Vol.10 No.12
Development of Internet-of-Services will be hampered by heterogeneous Internet-of-Things infrastructures, such as inconsistency in communicating with participating objects, connectivity between them, topology definition & data transfer, access via cloud computing for data storage etc. Our proposed solutions are applicable to a random topology scenario that allow establishing of multi-operational sensor networks out of single networks and/or single service networks with the participation of multiple networks; thus allowing virtual links to be created and resources to be shared. The designed layers are context-aware, application-oriented, and capable of representing physical objects to a management system, along with discovery of services. The reliability issue is addressed by deploying IETF supported IEEE 802.15.4 network model for low-rate wireless personal networks. Flow-sensor succeeded better results in comparison to the typical - sensor from reachability, throughput, energy consumption and diversity gain viewpoint and through allowing the multicast groups into maximum number, performances can be improved.

The present study was designed to identify intra-varietal diversity via SSR markers within ‘Askari’ and ‘Keshmeshi’ (Vitis vinifera L.). These two semi-seedless grape cultivars are used as table grape and raisin. Some accessions of these cultivars are morphologically different. For instance, some accessions had big berries with big bunches and empty seeds, whereas others had small berries in small bunches with soft seed traces. In order to evaluate these differences at the genetic level, we selected 14 SSR loci to evaluate intra-cultivar diversity. In total, 42 accessions of ‘Askari’, 10 accessions of ‘Keshmeshi’ and one accession of Sultanina as a control were analysed, using a capillary electrophoresis fragment sizing system. Genetic analysis discriminated six accessions of ‘Askari’ (No. A3, A21, A31, A44, A46, and A114) which were different from other accessions. These accessions were also different in some morphological traits. Accessions no. A3 and no. A21 had soft seed traces with berries and bunches that were smaller than others. Other accessions had empty seeds. Accessions no. A44, A46 and A114 had big bunches, big berries and empty seeds. In accession no. A31 berry shape was approximately round vs. oval shape in other accessions. The remaining accessions (36 accessions) were identical in 14 SSR loci. In ‘Keshmeshi’ four different accessions (No. K6, K8, K15, and K27) were discriminated in genetic analysis. In accessions no. K6 and no. K8, the number of bunch and yield per vine was higher than other accessions. In accessions no. K15 and no. K27, berries and bunches were bigger than others and the number of seed traces were higher than other accessions. Other six accessions were identical in14 SSR loci. Cluster analysis of all three cultivars divided accessions to three groups (each cultivar in one group) at 0.67 similarity coefficient. Our study showed SSR markers can be useful for identifying of intra-cultivar diversity.

Talesh is the Unique Sample of Cultural Tourism Attractions
Rahim Sarvar,Mohsen Ranjbar,Sharareh Nourani 세계문화관광학회 2009 Conference Proceedings Vol.10 No.0
Talesh is the name of a country in green Gilan province which is located in the north of Iran. It is located at 4854' east longitude and 37 48' north latitude.This area with nearly 270000 population is one of the most wonderful and various cultural tourism region of Iran. This area is about 90 Km long and 30Km wide, a unique center of cultural attractions that is mingled with historical and natural attractions, that it's ancient is 3000years ago. There is Alborz mountains at west part of Talesh and Caspian Sea at east part of it. At this apparent small area we can observe a world of variety, local markets, historical traces special traditions and civilities, cultural and sporting ceremonies and special program to plant and harvest of rice, producing silk and fishing, the method of making house, different kinds of carpet, hand crafts, seasonal emigration are just a small part of tourism attractions of this area. The main purpose of this article is introducing Talesh area as a complete collection of cultural tourism attraction not only in middle east but also in the world. To prepare this article all the documents has been researching.
Paradoxical class: paradox of interest and political conservatism in middle class
Rahim Baizidi 서울대학교행정대학원 2019 Asian Journal of Political Science Vol.27 No.3
Considering the importance of class analysis in understanding social issues, the present paper has used this level of analysis as an important factor in the economic, social and political attitude of society. Accordingly, three main classes, including the upper class, the middle class, and the lower class have been divided and their attitudes towards redistribution of wealth (as a non-conservative policy) have been evaluated. Given the current economic inequality, in the case of adopting the policy of redistribution of the wealth, the lower and middle classes will benefit economically, since they possess less wealth than their population percentage. Nevertheless, the results of the survey revealed that only the lower class assented to redistribution of the wealth, while upper and middle classes largely dissented to it. The study seeks to address this question that why the middle-class dissents to redistribution of wealth, despite its economic benefits. In order to answer that, we resort to another survey of the members of the middle class, in which the role of non-economic interests – including social and political interests, has been evaluated. Finally, the conclusion suggests that the majority of the middle class faces a paradoxical status in the area of economic, political, and social interests.

<P>Image quantification studies in positron emission tomography/computed tomography (PET/CT) are of immense importance in the diagnosis and follow-up of variety of cancers. In this review we have described the current image quantification methodologies employed in (18)F-fluorodeoxyglucose ((18)F-FDG) PET in major oncological conditions with particular emphasis on tumor heterogeneity studies. We have described various quantitative parameters being used in PET image analysis. The main contemporary methodology is to measure tumor metabolic activity; however, analysis of other image-related parameters is also increasing. Primarily, we have identified the existing role of tumor heterogeneity studies in major cancers using (18)F-FDG PET. We have also described some newer radiopharmaceuticals other than (18)F-FDG being studied/used in the management of these cancers. Tumor heterogeneity studies are being performed in almost all major oncological conditions using (18)F-FDG PET. The role of these studies is very promising in the management of these conditions.</P>
