Industrial PRESS units are divided into two primary groups, single-ACTION and DOUBLE-ACTION. A single-ACTION PRESS unit has a mechanism that guides drawing slide. A DOUBLE-ACTION PRESS unit has a blank holder mechanism as well. A DOUBLE-ACTION PRESS die has more weight and is more expensive than a single-ACTION one. For the following reasons, single ACTION die, uses for DOUBLE ACTION PRESS that blank holder mechanism is not in use in this situation and unit changes to single ACTION. The conclusion of this work is the dynamics and stress analysis of the later state. In this work, for a kinematics analysis, a mathematical model of the mechanism is presented. Later, a dynamics analysis of the DOUBLE-ACTION mechanism with a standard die and with a small die of a single-ACTION state is provided. This work is concluded by the stress analysis of the two states. Conclusions yield that the use of a single-ACTION die for a DOUBLE-ACTION PRESS increases the force and stress in the ram mechanism joints. Thus this usage in the DOUBLE-ACTION PRESS increases the failure chance in the PRESS mechanism.

Introduction: Effective plaque removal is an important factor in the long-term clinical success of dental implants. The aim of this study was to compare the clinical efficacy of a powered toothbrush (Power Cross-ACTION) and a manual toothbrush (Cross-ACTION) in the control of plaque and soft tissue inflammation around implants supporting mandibular overdentures.Materials and Methods: This study was a cross-over clinical trial. The subjects included 10 edentulous subjects, aged 47-73 years, with removable mandibular overdentures supported by 2 unsplinted implants, all the subjects wore maxillary complete dentures. The study consisted of two 4-week phases separated by a 2-week interval. In each phase each subject randomly used one toothbrush type. Two days prior to each phase, the implants were polished. Plaque and bleeding indices were recorded before and after brushing. Data was analyzed by t-test using SPSS software (a=0.05).Results: Both toothbrushes reduced the indices under study. Means of plaque index decreases were 0.5 in manual toothbrush and 0.44 in powered toothbrush. Means of bleeding index decreases were 0.27 in manual toothbrush and 0.3 in powered toothbrush. There were no statistically significant differences between the two toothbrush types in changing plaque index (p value=0.88) and bleeding index (p value=0.91).Conclusion: Both toothbrushes were efficient in plaque control around implants which supported mandibular overdentures and there was no difference between them. Patients can use one of these toothbrushes depending on personal preference and comfort.

The PRESS appeared after Abbas Mirza’ s modernization efforts and the Iranian students returning home from Europe. The first newspaper published in Mohammad Shah‘ s time and after issuing the constitutional decree the Internal newspaper except the newspapers in exile praised the Shah's orders and published news of the court. Therefore, in this research PRESS is called the monarchy (courtier) political system in Iran. The constitutionalism order and fights for it leads to more freedom for the PRESS and newer ideas and concepts were created in public life that differed from the monarchy political system in Iran. This difference is the core of this research and is called DOUBLE consciousness. On the one hand, from the advent of the PRESS to the end of the 13th solar century when Reza Shah involved in politics, fundamentally the PRESS were a new phenomenon. On the other hand this phenomenon was supposed to work on political and social fields but it was not in accordance with individuals and public awareness. Consequently, this difference caused a contrast with the public awareness and opinions. In this framework, the main focus of this research is on how the PRESS worked and the appearance of this kind of awareness in Iran’ s history with a discovering approach until 1299 when Reza shah involved in politics.

Objective: Mechanical plaque removal namely tooth brushing is the most commonly used oral hygiene technique. Efficacy of tooth brushing is influenced by the design and shape of toothbrush. This study aimed to compare the efficacy of two common Iranian toothbrushes with a foreign made one in plaque removal.Methods: This clinical trial was conducted on 30 female dental students in Babol University, School of Dentistry using simple randomized sampling. Oral B Cross ACTION(Germany), Panberes Cross ACTION and Panberes Classic (Iran) toothbrushes were compared. Students were asked not to brush their teeth for 24 hours before the first visit. At the first visit, subjects received oral prophylactic procedures and the baseline plaque index was recorded before brushing for all subjects using 0' Leary plaque index. In order to match the conditions, Bass tooth brushing technique was instructed to subjects. Students were then randomly divided into 3 groups of 10. The subjects were provided with the three toothbrushes for use in the first, second and third weeks. The plaque index was recorded after using each toothbrush for one week. Paired t-test was used to compare the efficacy of toothbrushes in plaque removal in the same subject while ANOV A was applied for the comparison between the three toothbrushes.Results: Significant reductions were observed in plaque index after using each toothbrush. Plaque index reduction was the highest for Oral B Cross ACTION and the lowest for Panberes Classic (P=0.001). Oral B Cross ACTION and a significant difference with Panberes Classic in mean plaque index reduction (P=0.018). Panberes Cross ACTION and Oral B Cross ACTION were not significantly different in this respect (P=0=797).Conclusion: Oral B Cross ACTION and Panberes Cross ACTION were not significantly different in terms of plaque index reduction. However, the mentioned two toothbrushes had a significant difference in this respect with Panberes Classic.

Introduction: Arbitration has a contractual nature and is subject to the sovereignty of the will of the parties, but in some cases, the legislator imposed the referral of claims to arbitration on the will of the parties and caused the contractual nature of the arbitration clause to disappear or be limited. By doing this, he has placed the arbitration outside the will of the parties. This issue causes some moral conflicts in the discussion of compulsory arbitration. Therefore, this research has been done with the purpose of examining the position of compulsory arbitration in Iran's legal system and the ethical challenges in it with a descriptive-analytical approach. Material and Methods: The research was a review method, in order to achieve the goal of the research, in addition to electronic education books and virtual education in this field, articles related to the research keywords from 2004 to 2022 from the databases of Civilica, Magiran, Sid, Researchgate, Science direct, was reviewed Conclusion: Based on the findings of the research, it can be concluded that compulsory arbitration in Iran has ethical challenges in the field of implementation and interpretation, the most important of which is the issue of the right to ACTION and judicial justice. In the context of ambiguities in mandatory arbitration, even if the method of arbitration becomes ambiguous, the arbitrator has the duty to find out the will of the legislator with the principles and rules of interpretation, which creates a moral conflict for the arbitrator.

BACKGROUND AND OBJECTIVE: In infertility without suffering tubal factor, IUI is the choice therapeutic method. Some studies recommended DOUBLE IUI for every cycle. Since DOUBLE IUI needs more laboratory materials and more expenses, so in this study it was tried to evaluate pregnancy rate in infertile couples after single and DOUBLE IUI.METHODS: This clinical trial study was performed on infertile couples referred to Fatemeh Alzahra or Babol Clinic hospital for IUI cycles. Patients divided into two groups. In the first group, 36 hours after HCG injection, IUI was done as a single protocol and in the other group; IUI was done 24 & 72 hours after HCG injection as DOUBLE protocol. Then data were analyzed by fishers exact test.FINDINGS: Two hundred and fifteen women participated in our study and their mean age was 26.02±5.5 and the mean (±SD) duration of infertility was 3.73 (±2.75) years. In the first group, pregnancy rate was 16.9% and in second group it was 19.6% without any significant difference between two groups. Also, there was no significant difference between groups in pregnancy rate with different etiology of infertility.CONCLUSION: Some studies recommended that DOUBLE IUI is more successful than single IUI But present findings suggest that there is no difference in pregnancy rate between single IUI and DOUBLE IUI.

Background and Objectives: Brucellae are gram-negative intracellular pathogens which cause zoonotic disease in humans. Clinical manifestations of brucellosis in human are variable and often are non-specific, and the diagnosis requires fast and accurate confirmation. Since the use of serum instead of whole-blood samples offers several advantages for nucleic acid amplification methods, in this study we developed an improved PCR assay for the rapid and specific laboratory diagnosis of human brucellosis directly from serum specimens.Material and Methods: DNA was extracted from 100 µL of serum from 30 patients with acute serologic brucellosis. The PCR reACTION was carried out with Specific primers. Second PCR reACTION for reamplification of the first reACTION products was designed.Results: a 223 bp conserved region on the sequence encoding the 31-KDa immunogenic outer membrane protein which is specific to the genus Brucella (BCSP31) and present in all its biovars was amplified in all serum samples.Conclusion: For confirmation and efficient amplification of the specific target, reamplification of the first PCR products had a sharper banding patterns with high sensitivity and specificity that might be considered as a new useful method for diagnosis of human brucellosis in serum specimens.

In this Research in order to recognize the approaches of local PRESS to the 9th Iran s presidential election, the related news contents of nine Newspapers with three (Right, Left & center) political tendencies were studied. The Statistical Sample of this research was the formal period of presidential political advertising (sixteen days) from May 26th 2005 till June 12th of 2005 (cxcepl off days). On the whole, 1572 articles were studied in 24 Categories. The Method of this research is content analysis. SPSS Software & X2 Test were used to study theelection s News Coverage.The research findings showed that between the three tendencies of the studied PRESS, all the articles had meaningful difference except the Headline in front page. The Results showed: In Local PRESS Nationalism is more than Localism. There is less attention to local Issues in the local PRESS.Bias to the candidate is positive In news, the fame value for local authorities is more than national Ones.
