Many factors are involved in urban heat island development,such as lack of green spaces,improper choice of building materials,densification,and other human *** aim of this research was to quantify the effects of land-use/land-cover(LU/LC)changes on urban land surface temperature(LST)during a 25-year period(1993–2018)for the semiarid Shiraz City in southern Iran using Landsat data(TM,ETM+,and OLI/TIRS)and machine learning *** main LU/LC classes,such as orchard,vegetation,bare surface,asphalt cover,and built-up areas,were identified using a support vector machine *** images were used to retrieve normalized difference vegetation index(NDVI)and normalized difference built-up index(NDBI).The results showed that the mean LST over the entire study domain increased considerably between 1993 and 2018,due to urbanization,decrease of green areas,and increasing industrial ***-up areas increased considerably by 25.8%from 80 to 100.6 km^(2) between 1993 and 2018,while vegetation cover decreased dramatically by 69.3%.Mean LST increased from 38.4 to 40.2℃ during the 25-year period with a significant increase of 3.9℃ between 2013 and *** addition,the Urban heat island Ratio Index(URI)displayed a substantial upward trend during the 25-year period.

Asmari Formation is deposited in the Zagros Foreland basin during Oligo-Miocene time. In the presented research, Sheykh Makan (north of Kabir-Kuh Anticline) section located at Lurestan Basin is studied to achieve an understanding of facies changes, paleoenvironment and also sequence stratigraphic framework (relative sea level changes) of the Asmari Formation. Results of this study revealed that 15 microfacies grouped to four facies belts named as tidal flat, lagoon, barrier and open marine are the main constituents. A homoclinal ramp is determined as the depositional setting of the Asmari Formation. In Sheykh Makan Section, studied interval contains three third-order sequences aging oligmiocene. It overlies gradually shaly Pabdeh Formation and is overlain by evaporitic Gachsaran Formatin.

The detailed kinetics of Fischer-Tropsch synthesis over an industrial Fe/Cu/La/Si catalyst was studied in a continuous spinning basket re- actor under the conditions relevant to industrial operations. Reaction rate equations were derived on the basis of Langmuir-Hinshelwood- Hougen-Watson type models for Fischer-Tropsch synthesis based on possible reactions sets originated from the carbide, enolic and combined enol/carbide mechanisms. Kinetic model candidates were evaluated by the global optimization of kinetic parameters, which were realized by first minimization of multi-response objective functions with conventional Levenberg-Marquardt method. It was found that an enolic mech- anism based model could produce a good fit of the experimental data. The activation energy for paraffin formation is 95 ***1-1 which is smaller than that for olefin formation （121 ***-1）.

In ancient Iran, in addition to defensive elements such as castles, fortresses, and fortifications, there were underground cities called dastkand. These cities had a shelter-protection function and provided safe space to protect residents when enemies attacked. In the scope of dastkand architectural studies, form typology, land-use typology, and provision of thermal comfort have been investigated in various studies but there is no study on dastkand defensive architecture, which is the main purpose of the present research. The research method is a mixed method (qualitative-quantitative). The required data are collected through a survey and then, analyzed using factor analysis in R method. The statistical population includes Iranian architectural heritage specialists and the sample size is estimated to be 165 persons. Sampling adequacy is confirmed based on the results of KMO test. The samples are selected using a non-probability sampling method. The obtained results indicate that ten factors have been effective in the architecture of Iran’s ancient organic shelters. In order from largest to smallest coefficient of variance, the factors include collective defense, multi-layered defense, environmental camouflage, path control, self-sufficiency, secret passage, sustainable architecture, residential values, covert surveillance, and cluster development.

The concept of virtual water in recent years has been proposed with the world’s water resource consumption management approach. Hashtgerd study area is one of 609 study areas of the country that is located entirely in Alborz Province. Average annual rainfall in this region was about 200 to 340 mm and the average agricultural production per year was more than one million tons and had more than 16 million cubic meters surplus recovery from underground water resources. The aim of this study is to evaluate resources and amounts of virtual water in the agricultural sector of the study area and its impact on the area water resources balance and ultimately provide solutions to reduce water consumption by the agricultural sector. The most important exported water products in Hashtgerd area in order of importance are peaches and nectarines (33% of water exports), plums (15% of water exports), vegetables (5.14 percent of water exports), cherry (4.7% of water exports) and wheat (6.5 percent of water exports). Virtual water trade balance of agricultural and horticultural products in the digital range is equal to 260+ million cubic meters. Density of agricultural lands can be mentioned as the main reasons for positive balance of virtual water trade in this area.

Objective： Interphalangeal joint con- tracture is a challenging complication of hand trauma, which reduces the functional capacity of the entire hand. In this study we evaluated the results of soft tissue distraction with no collateral ligament transection or volar plate removal in comparison with traditional operation of contracture re- lease and partial ligament transection and volar plate removal. Methods： In this prospective study, a total of 40 pa- tients in two equal groups （A and B） were studied. Patients suffering from chronic flexion contracture of abrasive trau- matic nature were included. Group A were treated by soft tissue distraction using pentagonal frame technique and in Group B the contracture release was followed by finger splinting. Results： Analyzed data revealed a significant differ- ence between the two groups for range of motion in the proximal interphalangeal joints （P〈0.05）, while it was not meaningful in the distal interphalangeal joints （P〉0.05）. There was not a significant difference in the degrees of flexion contracture between groups （P〉0.05）. Regression analysis showed that using pentagonal frame technique significantly increased the mean improvement in range of motion of proxi- mal interphalangeal joints （P〈0.001）, while the higher the preoperative flexion contracture was observed in proximal interphalangeal joints, the lower improvement was achieved in range of motion of proximal interphalangeal joints after intervention （P〈0.001）. Conclusion： Soft tissue distraction using pentagonal frame technique with gradual and continuous collateral liga- ment and surrounding joint tissues distraction combined with skin Z-plasty significantly improves the range of mo- tion in patients with chronic traumatic flexion deformity of proximal and/or distal interphalangeal joints.
