In this research, the performance of Carbone nanotubes (CNT) as a sensing material and adsorbent for the detection and removal of Amoxicillin was investigated. at the first, the structures of Amoxicillin and CNT were optimized with Gaussian program. Then, using the molecular docking strategy and its grading system, they were computed the arrangement of 10 structures with more negative binding energy than other . Finally, for the best arrangement of Amoxicillin with CNT, molecular orbitals evaluations and depedents parameters , binding energy and other thermodynamic parameters evaluated, the results indicated that the adsorption of Amoxicillin antibiotic on CNT was an exothermic. This procedure was carried out at 298 K and 1 atm. Finally, the QTAIM calculations were performed to evaluate the type of interaction and bonds created between amoxicillin and CNT.

The aim of study was to determine changes in the personality organization in different time serials of Transference focused psychotherapy in Cluster B personality disorders.

A quasi-experimental of the type Multiple Time–Series Design. 32 patients with Cluster B Personality Disorders selected by available sampling method based on Milon clinical multiaxial inventory (III) and input and output criteria. Patients were randomly assigned to two experimental and control groups. 51 Transference focused psychotherapy sessions performed individually for one year in experimental group. One pre-test and three post-test of STIPO performed for both groups in different periods of treatment.

The resuls showed that there were no significant changes in first stage of treatment. But significant changes occured in all of dimensions of personality except rigidity. And also the most rate of change was in third stage of treatment (sig<0.05).

According to the results, it can be externalized Transference focused psychotherapy as an effective treatment can be improving Cluster B personality disorder

Southern coastal zones of Iran are divided into Persian Gulf and Mokran regions. These areas have subtropical and arid-warm climate with relatively long hot summers and short and slightly cool winters. According to greenhouse development program, it is planned to add 48350 hectares to the greenhouses during a ten-year period. The southern coastal zones are projected to have a share of about 13000 hectares from this development. Water scarcity, harsh climatic conditions, need for increasing agricultural productivity, need to alleviate poverty and improve people's livelihoods, and possibility of exporting products to Arab countries, have increased the need for greenhouse cultivation in Iran’s southern coastal zones, with the use of special and inexpensive structures. In this article, while analyzing the climatic conditions of each province of the coastal zone, attempt has been made to present the type and technical characteristics of controlled environments suitable for plant cultivation in each province. In this regard, for south of Sistan and Balouchestan province as a subtropical region, naturally ventilated greenhouses with permanent roof and side opening vents, dome-shade net houses and flat-roof shade net houses were suggested. For south of Hormozgan province with warm-humid climate, naturally ventilated greenhouses with the ability to open and close roof and side vents were recommended. For Boushehr province as well as for south of Khuzestan province, naturally ventilated greenhouses with the ability to open and close roof and side vents with higher ventilation ratio and with supplemental heating systems were recommended.

Today tourism is considered as the largest service industry in the world. Because of the regional situation, professional staff and quality medical centers, health tourism is one of the areas where our country has a high competitive advantage. In spite of these advantages, attracting customers is a challenge in becoming a medical tourism brand. In this regard, this paper examines the challenges of medical tourism branding.

The present study is applied in terms of purpose, exploratory in nature and qualitative in terms of approach. In this research, the data, collected from interviews with 16 people including two groups of medical professionals and medical tourists in Ardabil province, were analyzed using the Grounded Theory Method in three stages (open coding, axial coding and selective coding).

In the analysis of data, 37 concepts from all interviews were extracted and finally, these concepts were categorized in selective coding in six groups of infrastructural, cultural-social, legal, ethical, promotional, and competitive challenges.

According to the results of the research, in branding the medical tourism in Ardabil, the basic challenges should be identified and the related concepts in each area should be considered.

The virtual water trade concept was devised about three decades ago and it is now considered as a way of balancing the distribution of water among countries and regions in attempts to confront with water scarcity. The background literature of virtual water has developed independent of economic knowledge and economists have not endeavored to theorize it. Based on this concept, the export of agricultural products from Iran has been under much criticism in recent years. This study attempts to provide a simple economic model that works with based on opportunity cost theory in combination with economic water productivity and virtual water trade concepts to evaluate major agricultural products of Iran exported or imported in a five-year period. According to the results, internal production of strategic crops has high opportunity costs. The exporting of fruits such as kiwi, citrus, grapes, watermelon, cucumber and tomato created high virtual water values, even higher than pistachio. However, under the water crisis conditions in Iran, these values are much lower than real value of water.
