The aim of designing structural members is to withstand against different Loading conditions such that the safety of the system could be preserved. The conventional method for designing of reinforced concrete members in Iranian concrete code is based on Load and resistance factor. Although, Load and resistance parameters are random variables, and in the mentioned Code the constant values have been designated for them during the designing procedure accounting these factors as the constants parameters will ultimately be led to the unsafe and uneconomical designs. The main purpose of this paper is probability-based designing of reinforcement concrete beams under simultaneous effects of bending, shear and torsion actions. For this purpose, analytical relations of the limit states for combination of bending, shear and torsion have been developed. Using this method, the structural designers could be fulfilled the designing of the RC beams based on the importance of structures and the required safety indexes of the owners. The next goal of this investigation is evaluation and calibration of Load and resistance factors for desired safety index. The economic and fully probabilistic designing of concrete beams for simultaneous effects of bending, shear and torsion are available by implementing the proposed design procedures. In order to calculate the safety indexes a computer program has been written in the MATLAB environment and the Monte Carlo simulation technique has been utilized.

Background and Aim: It is believed that a period of healing, approximately 3-4 months for mandible and 4-6 months for maxilla, are required to ensure osseointegration. Recently, a new method called Immediate Loading of implants have been proposed. This method provides improved stability of the implant by the immediate support of an iterim prosthesis. The aim of this study was to evaluate the success rate of the Immediate Loading single OPILS dental implants.Materials and Methods: Thirty-nine patients, including 26 females and 13 males, at the minimum age of 18 and maximum age of 54 years old, received 48 OPILS dental implants. In this prospective study, all samples were non-smoking, without any systemic disease or psychological problem. In all cases, and acrylic prefabricated crown was placed immediately after implant surgery. The definitive metal-ceramic crown was placed 2.5 months later in mandible and 5.5 months later in maxillae. Lack of pain, pus, implant immobility and less than 1mm bone loss were criteria of success.Results: The oral hygiene of females were better than males, 26 women had plaque index (0) and 11 of them had plaque index (1) where as out of 13 male subjects, 4 had plaque index (0), 6 had plaque index (2) and (3) had plaque index (3). The mean vertical bone loss, on mesial and distal parts, were less than 1mm, with the min. of 0 and max. of 0.4mm and the average of 0.2mm. All implants pass the defined criteria of success.Conclusion: On the basis of this short-term study, in single tooth cases, OPILS implants of Neo-Dent system can be Loaded immediately.

One of the obvious reasons for most disorders in network service provisioning is network path congestion. Congestion avoidance in today's networks is too costly and sometimes impossible. With the introduction of SDN, centralizing the equipment's control plane has become possible. This paper presents an enhanced method named ESV-DBRA to avoid congestion in multi-tenant SDN networks. At first, ESV-DBRA monitors the traffic Load and delay of all network paths for each tenant individually. Then, by merging the parameters obtained from the monitoring, the Service Level Agreements (SLA), and a novel proposed cost function, it calculates the cost of the network paths per tenant. As a result, traffic for each tenant is routed through the path/paths at the lowest possible cost from the tenant's perspective. Next, the bandwidth quotas will be calculated and assigned to the tenants over their optimal routes. Afterward, whenever congestion is likely to occur in a path, ESV-DBRA automatically changes the route or bandwidth of the tenants' traffic related to this path to avoid congestion. Related algorithms are also proposed.Eventually, simulations show that the proposed method effectively increases bandwidth utilization by 10.76%.

In the last two decades, there have been many developments in the field of gender in Iran, which has made the gender component one of the most important factors explaining the new society. Women have always been the subject of power, and imposing restrictions on them in the form of laws, custom, Sharia, clothing and lifestyle has been a patriarchal ideological approach. The women's movement in Iran has gained international dimensions. This movement has a history of a hundred years and is influenced by the waves of transformation of women's thought and the transformation of the concept of power at the international level. Despite all this effectiveness, there is a delay of several decades in the opinion and political action of women in Iran. In this research, we examine the role of power evolution in women's demands in Iran and pay attention to everyday politics that has presented itself in the form of criticizing ideological discourse and reaching liberation as everyday life and benefiting from human freedoms. The question of this research is, what conceptual evolution has the women's movement in Iran had in the years after the revolution? The findings of the research show that the women's movement in Iran is transitioning from ideology to everyday politics, and women's demands have turned into protests against power interference in their private lives and opposition to body subjugation and efforts to achieve human rights.

The purpose of the present study was to investigate the effect of generative learning teaching based to pattern cognitive Load on the memorization math of 7th grade students of in the academic year of 2021- 2022. The research method is quasi-experimental with pre-test and post-test with four groups: two control group and two experimental groups. The statistical population of the study consisted of all 7th grade male and female students of District 2 of Mashhad city that 112 person sample was selected by single stage cluster sampling method. The subjects in the experimental group involved in generative learning based to cognitive Load in 16 sessions and the control group did not receive any interventions. The research instrument consisted of a 20-questions researcher-made test. To analyze the obtained data, Multivariate analysis of covariance and SPSS version 24 software were used. The results showed that generative learning teaching based to approach cognitive Load have a positive and significant effect on 7th grade students' memorization math. Based on the findings, it can be concluded that one of the effective training on math memorization students is the use of generative learning on the based Load cognitive pattern.

The concept of citizenship rights and demand is one of the concepts that has attracted the attention of citizens and the government in the modern world. Previously, such concepts were unknown to the people, but today, citizens have gained more awareness of their citizenship rights. Since demandingness is often considered a characteristic of modern societies, it seems necessary to study the situation of demandingness in a traditional-religious context. Therefore, the current research has been conducted with the aim of knowing the economic demands of women and the status of their demands in the city of Yazd. With the strategy of grounded theory and using theoretical and targeted sampling, 13 women were selected for semi-structured in-depth interview and the sampling process continued until the complete information saturation stage. The obtained data were analyzed after converting to text using three stages of open, central and selective coding. The emerging categories include the interaction of rights and duties of the state/nation, comprehensive economic concerns, material concessions, previous demanding actions, dissatisfaction with economic-political dysfunctions, reduction of economic resilience, economic actions directed at self-directed at others, etc., the results of which It was presented in the form of paradigm model and experimental theory. The general results show that the citizens try to realize it with different strategies, either by economic demands or by avoiding demands. Also, the consequences of the fulfillment or non-fulfillment of demands have been presented at the social, political-religious and psychological levels, which require the attention of policymakers in this field.

Background and aim: Results of Implant therapy have always been evaluated on the basis of radiographic and clinical assessments such as percussion, focused only on determination of peri-implant bone resorption and implant failures. These measurements are qualitative only and could not be considered as quantitative and reliable scales for the evaluation of stability; So they could not be statistically analysed. These difficulties could be overcome by using Resonance Frequency Analysis (RFA).RFA could be considered as a proper comparable measurement in evaluation of implant stability. This study aimed to evaluate and determine the stability of over denture Loaded implants in a number of private clinics during 2006 -2007.Materials and Methods: This cross – sectional study was conducted on 13 patients provided with Swiss plus implant Therapy Loaded by over dentures for the first step, each patient was evaluated regarding Implant Quality health Scale and put into one of five groups. Abutments were then removed and fixtures were evaluated by Osstell Mentor Instrument following the attachment of Smart peg to fixtures, Implant Stability Qoutient was then determined. Sampling was done in a sequential approach and obtained data were statistically analyzed using X2 and t-test.Results: Fourty three implants were evaluated in 13 patients, 21 in maxilla and 22 in mandible the mean I.S.Q.Equaled 70.36 ± 4.43 in maxilla and 79.1 ± 3.51 in mandible. The total mean ISQ (bimaxillary mean ISQ) equaled 84.36 ± 5.94.Conclusion: Regarding the obtained results, Over denture Loaded implants are absolutely successful treatment plans in mandible, according to their higher ISQ compared to maxilla. It is also demonstrated that stability of implants at each step of treatment Procedure is influenced by primary stability during placement more than any other factors. Primary stability itself is mainly influenced by surgeon`s experience in the proper following of surgical protocol.
