Our regression models revealed that male gender is a risk factor for hiatal hernia, GERD, gastric ulcer and duodenal ulcer but not for other upper endoscopic findings.

Energy supply security is one of the strategic issues of all states. Beside the energy supply management, the section that has received less attention is energy demand management. According to importance of residential and commercial sectors in energy consumption, in the present study energy demand of these sectors is estimated using linear and exponential functions and the coefficients are obtained from PSO algorithms. 72 different scenarios with various inputs are investigated. Data from the years 1968 to 2011 are used to develop the models and select the suitable scenario. Results show that an exponential model developed based on particle swarm optimization algorithm has had the best performance. Based on the best scenario the energy demand of residential and commercial sectors is estimated 1718 Mega barrel of crude oil equivalent up to the year 2032.

Majority of the high rate gas wells in the world are completed with Monobore completion system. The conventional sequences of running Monobore completion in giant gas field of SouthPars are in three steps: Run No. 1 which includes running Liner and liner hanger by drill pipes (DP) and normally followed by cementing behind liner, Run No. 2 which includes Running Tie Back production Packer with 15 ft Polished Bore Receptacle (PBR)by setting tool and DP and finally Run No. 3 which includes running completion string with upper seal stem and at the end complete the well with proper space out. Running of tie back production packer with setting tool and DP in one step and running upper seal stem by tubing in last step has some concerns (More Rig time, cost, safety, etc). Feasibility Study and research was carried out to check the possibility of combining the run No. 2 and 3 together. A new method has been developed and after successful surface test it was run in one of gas wells in South Pars giant gas field in Persian Gulf. All pressure tests after installation were satisfactory. This procedure saved almost 1.5 day of rig time and protected seals against mechanical damage while running in the hole.

Nowadays, modern food preservation techniques have emerged in the last decade. Recently, a combination of nanotechnology and active packaging allowed the incorporation of bioactive compounds such as essential oils into nanoscale electrospun fibers. This phenomenon provided a new horizon in food safety and preservation. The incorporation of essential oils into electrospun nanofibers can extend the duration of antimicrobial and antioxidant activity of essential oils, which subsequently leads to longer shelf life, better preservation, and superior quality of food. In the current paper, the essential oils which incorporated into nanofibers were reviewed. The fabrication of nanofibers usually carried out using different substances by applying various manufacturing methods including needleless and needle-based electrospinning techniques. In this study, an emphasis on antioxidant and antibacterial effects of electrospun nanofibers loaded with essential oils and their application in food models has been carried out. Nevertheless, other challenges of using nanofibers incorporated with essential oils such as the impact on organoleptic properties, cytotoxicity, and durability were discussed to achieve a holistic view of applying the electrospinning techniques in the food industry.
