Introduction: The purpose of this research was to evaluate the radiopacity of calcium enriched material cement and mineral trioxide aggregated fillapex with 3 types of sealers: Endoseal, and AH26 at different focal distances of 15 cm and 30 cm. Methods: The research method was an experimental and lab trial. In this research, 3 endodontic sealers: Pulpdent, Endoseal, and AH26 and two root filling material: mineral trioxide aggregated fillapex and calcium enriched material cement were studied. From each material 6 samples were prepared. The samples were prepared on a glass slab by stirring with the help of a spatula and placed in molds with dimensions of 1 x 5 x 5 mm. Radiographs were prepared with the PSP Fire CR digital sensor system at a distance of 15 and 30 cm from the samples. Radio opacity information obtained was interpreted by Quantor Dent for Windows software. The obtained results were analyzed by SPSS version 16 statistical software and Two-way ANOVA and Tukey test. Results: The results showed that AH26 had the highest optical density value and calcium enriched material cement had the lower radiopacity. There was a significant difference between the radiopacity value of the 5 studied materials (P<0. 05). Conclusion: All the studied materials had the minimal standard of radiopacity.

Background: The infertility as a stressful happening is accompanied by a variety of psychological problems. The present study mainly aims to compare material intimacy and satisfaction in infertile and normal women.Methods: This is a casual- comparative research which 50 infertile women and 50 fertile women were selected and compared in an available way and voluntarily, out of those referred to Kermanshah Imam Hossein Hospital in 2014. The information was collected through two questionnaires including enrich and material satisfaction.Results: The study findings indicated that material intimacy in fertile women is significantly higher than the women who are infertile for any reason, and also, the mean of the perceived material satisfaction in normal couples is significantly higher than the infertile couples. The present study had secondary findings as well, which indicated that there is a negative relationship between material intimacy and duration of marriage. In other words, since the time of marriage, whatever material life is spent, intimacy and warmth of the relationship is diminished.Conclusions: It can be concluded from the results of research that fertile and child is causing more warmth and intimacy, marriage, even though the damage is based on the results of this study routine and intimate relationship with time is reduced.

Every year in Iranian ports dredging is spending a considerable sum. Correct assessment of dredged material and ensuring that the dredging was done in the desired location is important. This article seeks to provide a way to assess the volume of dredged material that has conditions: (1) have adequate theoretical basis, (2) by the host, supervisor and employer independently applicable, (3) repeated so that in the event of a dispute between performer and observer, is done by a third party, (4) can be a single procedure in the PMO and Ports introduced, (5) it can be used to estimate the exact volume Before performing dredging operations used and (6) of the existing technologies used and its implementation does not impose costly.The main idea of this paper is to provide a method for processing hydrography data to estimate the volume of dredging operations and possibly to insert it in the (RFP) and then measuring it during operations or after it. For this, using mathematical triangulation Delaney three bed early, simulated surface and the seabed dredged and the difference between the first substrate and the estimated volume of operations and of different simulated first bed and the bed was dredged, the volume of operations carried out by the has come.

Is there beyond of our body the thing that does certain deed for us? This is a question that has a long antecedent in the history of science and philosophy. Spirit, soul, mind, brain etc are answers that have been put to this question. As for, what is their nature? Is it a problem that has been always discussed?Nowadays, a part of philosophy that studies this problem is called "Philosophy of Mind". Although it is not really a new matter in philosophy, it has not a long time as a distinct part of philosophy. As for, what is stressing at present is the material statement of the discussed matter. The three theories of behaviorism, mind- brain identity and functionalism are considerable in this area.This article is seeking to state these theories and criticize them.

The purpose of this paper was to review the composition, sealing ability, biocompatibility and various physical properties of cold ceramic (CC) material that potentially used as a root filling material. The review of the articles was performed by electronic and manual searching methods regarding the properties of CC from November 2000 to May 2016. The results revealed that there were many published reports carried out on the properties of CC. Only one article had extensively studied the composition of CC, five studies had investigated the sealing ability of CC, three articles had studied the biocompatibility, and some studies had investigated the radiopacity, setting time, pH value, and solubility of CC. It was concluded that CC material had good potential for endodontic use. Furthermore, clinical studies are needed in these areas.

One of the classes of the project schedule is the material Procurement Scheduling (MPS) problem, which is considered besides the material allocation to warehouse (MAW) problem recently. In the literature, the Simultaneous Solution of MPS-MAW is investigated by considering one warehouse and unlimited capacity of the warehouses most of the times. In this paper, we propose the propositional and mathematical model of the simultaneous MPS-MAW with multiple warehouses and the limited capacity at the whole of the horizon planning for each warehouse. The proposed model aims to obtain the best ordering point, selection of the best suppliers, the best activity start, and the fair material distribution to the warehouses as possible by the given objective function. The proposed model is NP-hard, so a metaheuristic namely simulated annealing is proposed to reach the acceptable but not optimal solutions in a short time. Also, to overcome the complexity of the model, the encoding of the decision variables have been done by adding the auxiliary variable. Comparing the solutions of the small problems with the exact methods shows the validation of the proposed SA. Also, the design of experiments shows the significance of the model and each SA parameters. Finally, by the optimum values of the SA parameters, the large problems have been solved at acceptable times.
