Introduction: Mobile learning enables users to interact with educational resources while in variable locations. Medical students in residency positions need to assimilate considerable knowledge besides their practical training and we therefore aimed to evaluate the impact of using short message service via cell phone as a learning tool in residents of Obstetrics and Gynecology in our hospital. Methods: We sent short messages including data about breast cancer to the cell phones of 25 residents of gynecology and obstetrics and asked them to study a well-designed booklet containing another set of information about the disease in the same period. The rate of learning derived from the two methods was compared by pre- and post-tests and self-satisfaction assessed by a relevant questionnaire at the end of the program. Results: The mobile learning method had a significantly better effect on learning and created more interest in the subject. Conclusion: Learning via receiving SMS can be an effective and appealing method of knowledge acquisition in higher levels of education.

The purpose of this study is to identify the pore types and distinguish the pore facies based on the diagenetic performance. The petrographic examination of 230 thin sections lead to the identification of a variety of primary and secondary porosities and show that the vuggy, moldic and intercrystalline pores have more frequency than the intraparticle, interparticle and fenestral pores. The plot of data obtained from thin sections on the ternary porosity graph used for determining the pore facies and their diagenetic trends and led to the identification of6 pore facies including depositional (PF1), moldic (PF4), and vuggy (PF6) pore facies, and also mixture pore facies PF2 (mixture of PF1 and PF4), PF3 (mixture of PF1 and PF6) and PF5 (mixture of PF4 and PF6). The comparison of petrography results with the well logs, core permeability and the calculated RQI and FZI values show that the pore facies which have touching pores, especially PF6 and PF1, have played the most important role in improving the quality of the reservoir, especially in the upper part of the studied zone. Also the pore facies which have separate pores, especially PF4, have the most influence in the reduction of reservoir quality relative to other pore facies, especially in the lower part of the studied zone. Most of the pores identified in the studied zone are the secondary porosity and diagenetic in origin. This demonstrates that the reservoir characteristics in the studied zone have been strongly modified by diagenetic overprinting. The most important diagenetic processes affecting the pore systems of the Asmari reservoir are cementation, selective and massive dissolution and dolomitization. Massive dissolution plays the most active role in the formation of touching vugs as well as enhancement of reservoir quality. Cementation and fabric selective dolomitization play the most active role in decrease of the reservoir quality.

In the southern part of the Kopeh Dagh basin, NE Iran, outcrop of the Kardeh fault damage zone in Mozduran carbonate formation provides an opportunity for investigation of the impact of faulting on permeability and porosity. For this purpose, three methods were focused on: 1) gas injection in oriented cores prepared parallel and perpendicular to fault strike and parallel to fault dip, 2) microscopic analysis and 3) determining variation of the degree of fractures connectivity in the fault damage zone. Results of tests show air-porosity and air-permeability increase from fault core toward host rock. Using microscopic studies, we attribute these variations to bioclasts destruction and filling, precipitation of calcite cement in fractures and pores, development of compaction structures such as stylolites and particle abrasion. Analyzing variation of the fractures connectivity in the fault damage zone in macro-scale shows degree of connectivity increases from host rock toward fault core (Y and X nodes). Clear dependence between this parameter and fluid flow is reflected by connected linear springs developed in the damage zone in close proximity to the fault core. Results of this study show that permeability in a fault zone is a scale dependent feature.
