The purpose of this research is to evaluate the effectiveness of hypnotherapy on the anxiety dimensions of 3 to 10-year-old children with autism during dental interventions.

The research method used was descriptive correlation and structural equation modeling through path analysis. The statistical population of this study included children with autism spectrum disorder who were referred to a private dental office located in Dana Complex, Busar Bridge, Rasht, Iran. A sample of 32 children with autism spectrum disorder, categorized as having mild to moderate levels based on the Wechsler-Hosh-Behr questionnaire recorded in their medical records, was selected using purposive sampling. They were then randomly assigned to two experimental and control groups, each comprising 16 participants. The sample size of 32 was chosen to account for potential dropouts. The experimental group received 8 sessions of hypnosis based on mindfulness, which was conducted by the first partner of the project, who had completed hypnotherapy courses. Data were collected using the Social Support Appraisals Scale (SSAS), Depression, Anxiety and Stress Scale (DASS-21), and Relapse Prediction Scale (RPS) questionnaires. Data analysis was performed using stepwise regression and structural equation modeling with SPSS-23 and Smart-PLS software.

The results showed significant correlations between the research variables, and all research hypotheses were confirmed.

Dental clinics are common places that induce fear and anxiety in dental patients, especially in children with autism spectrum disorder. This leads to negative emotions in the patients. Therefore, hypnotherapy is potentially a powerful method to control and reduce these negative factors, helping to better prepare their minds for optimal dental services.

This research is a laboratory study to improve the geotechnical properties of fine-grained soils. For this purpose, agricultural waste ash such as sugarcane bagasse, rice husk and almond husk have been used. In this regard, the effect of using ash of the mentioned fibers with at 4, 8 and 12 weight percentages on fine grain clay soils has been investigated. The compaction test results indicate that these additives generally increase the optimum soil moisture and the maximum optimum moisture was observed for the samples made with 12% ash. Also, based on the results of the unconfined compressive strength test, the studied additives have increased the uniaxial strength of the soil. The samples made with 12% ash were the most effective, so that the addition of 12% bagasse ash increased the soil resistance by 117%, and the addition of 12% rice husk ash and almond husk ash increased the soil resistance by 89, 80% respectively.

In this paper, a coupled fluid flow-geomechanical simulation in a deformable porous medium using finite element numerical method is presented. This model includes solving conservation of mass and momentum balance equations for solid framework and fluid phases. These equations are based on the Biot consolidation theory. Fluid pore pressure and solid-phase displacement have been selected as the primary variables in these equations. The governing equations are discretized using finite element method. The final equation system is then solved in a fully coupled process which was conducted by using MATLAB software. In this process, convergence and stability of results are guaranteed. Then, Mendel’s problem is solved using a proposed model and the results are compared with the analytical solution of the problem. The proposed model shows a very good agreement with the analytical solution, which indicates the accuracy of the model proposed in this article. Finally, this model is used to simulate the discharge of water from a sand column with a two phase saturation approach. The main priority of this study is providing precise formulations, applicability, and the ability of finite element in modeling coupled fluid flow and deformation in a porous medium.

Permission contracts are being told that the main effect is to make leave or permission. These contracts are based not only on the composition but also on the willingness of people. In fact، the permission must be supported by its source، and if deprived of the support stand، it''ll lose its life and identity. So this will result in the end of the legal acts. In the matter of dissolution of permission contracts in the civil law، legislator has called certain factors which provide the abolition of legal acts and permission through impeding the permission and its creator and source. The study of the following basics of abolition of permission contract indicates that the stipulated cases have been told to be allegorical and refer to common factors، in this extend. Investigate the function of human brain and identify the origin of intentional acts show that the part of brain that called the cerebral cortex in cases where the activity is stopped، the will of a person is gone، and the contract is abolished.

The Iranian civil code has limited the effects of unknown condition to nullification of such condition provided that it results in ignorance with respect to consideration. The code conveys no explicit provision concerning the effect of such condition not resulting in the ignorance. Unknown condition refers to a condition on which there is not complete and comprehensive knowledge.This article legally analyses this condition, as contained in lossfull and dilatory contracts in Imamich jurisprudence and legal norms separately. According to imamich jurisprudence, intertieon of an unknown condition, as defined above, is permissible for dilatory contract, not derogating the permissibility of such contract. This approach has been followed by the Iranian Civil code. But for lossfull contract, different views have been offered by fogfaha. It seems that the Iranian legislator has followed those believing that an unknown condition stipulated in lossfull contracts, always result in ignorance to the considerations and nullify the contract. It should be noted that the consideration itself is void.

Letting contracts are those in which, their main effect is making permission. In this type of contracts, at the result of offer and acceptance, permission is obtained. Of the features of permission, is its dependence on the will of the contracting parties. Thus, in any case, that the will of person disappears, permission is void. Permission void, causes terminating legal operation. The study of brain anatomy shows that the cortex is the source of human will and in the cases that the activity of brain, named cortex, is stopped, the will disappears, the permission is missing, and the contract is terminated. Civil law, knows death and madness, and insanity, as the tools of letting contracts termination. But in other cases, the person in whom, his will is affected, and the content of consciousness is reduced, it is silent. The study in this case show that, when the activity of bran stops, or his consciousness reduces as madness, because of alcohol, drugs, psychotropic substances, the permission is missing, and the contract is terminated.

Noor Medical Imaging Center was using a viewing station as Dicom-Server when all imaging devices like Spiral CT and MRI was sending their images to this computer. Therefore, other viewers in PACS network could access to images of server via Di-com-Query and imported them to their computer for diagnosis. In this plan a single computer received images from two imaging sources and compressed them for archiving. Meanwhile if another viewer had a request, it should search patients and sent images to that computer.Considering capacity limitations, images must be removed to CD. Hence, if physician wanted to access to the older images, he/she must wanted computer administrator to retrieve images from CD to server. Considering all above problems we planed a Di-com-Server with these futures: 1) Each imaging device must send images to its own unique archiving computer (we named it DicomX). 2) Capacity of each DicomX could be increased via adding new hard disks. 3) For DVD backing up, images must send from DicomXs to Query-Server computer 4) Query-Server stored patient information in its Database for searching services. 5) DicomXs must re-send each received images to predefined viewers for eliminating of query of new studies. That design was working well until installation of MSCT with arising of two problems: 1) DVD backup manner didn''t work, as computer administrator couldn''t write many DVDs and reconstruction of damaged HDD from DVDs is not applicable 2) Internal networking traffic between DicomXs and Query-Server was still high. For solv-ing the problem, we stored Dicom images on two hard disks in each DicomX. One for archiving and another for backing up, instead of using DVDs. Therefore, DicomX just send patient information to Query-Server for reducing of network traffic. In our work, Viewing Stations just are used as Diagnostic Computers and multi-processor Dicom-Server satisfies archiving needs.

Appropriate electronic medical report-making soft-wares help physicians to personally generate records for paper printing and ePR access. Flat data-sheets with check-boxes that have been already used in traditional medical paper reports, do not satisfy today''s physician demands for more professional reports.Alternatively, Structured Reporting (SR) as the modified version of flat check-box based reporting method is being selected. In this method, items are nested in a hieratical tree so that each reporting item includes several substitutions. Hence, computer generates professional sentences with logical pre-defined combination of selected items. In our work, on the basis of SR method, we provided solution for reporting of Endoscopy procedures that is accepted by several Gastroenterologists as a proper software. In addi-tion, successful results in generation of ePRs using SR are newly achieved in Cardiology.
