Organizations need to make decisions to maintain, upgrade valuable forces, and make effective use of human resources to achieve development and success in today's changing environment. One of the most important steps that can be taken in this regard is to pay attention to job anchors and to plan and implement strategies for personal and organizational goals. The main purpose of this research is to discover and validate the components of anchor strategies of staff working in Tehran General Education Department. The statistical population of the study consisted of 15 organizational experts who were purposefully selected to implement the Delphi method to discover the underlying factors. Using Cochran formula, 270 individuals were selected by stratified random sampling. Internal consistency of item validity and composite validity index were used to validate and validate constructs (mean variance index and Fornell Larker index) as well as content validity for validation. Delphi method was used to identify the underlying factors and structural factors of job anchor strategies and confirmatory factor analysis was used for validation. The research findings showed that staff anchoring strategies in the general office include: personal development strategies (psychological empowerment, talent management and surrogacy) and organizational development strategies (improving promotion and appointment system and improving performance appraisal system).

Statement of Problem: A few studies have been conducted about bioglass posts.Aim: The aim of this study was to compare bioglass posts with prefabricated metallic posts in clinical performance of extensive composite restorations for anterior endodontically treated teeth.Materials and Methods: Sixty endodontocally maxillary anterior teeth, with horizontally or vertically destruction were selected. Teeth were divided into two groups based on the kind of post: Metallic prefabricated parapost and bioglass post. Each group was divided into three subgroups based on anterior bite: normal, deep bite and edge to edge. Gutta-percha was removed from 2/3 of canal length for parapost and 1/3 for bioglass post. After etching with phosphoric-acid (37%) and applying dentine bonding Syntac, Duo cement was used for the adhesion of bioglass post and a self cured composite (Degufil) for parapost. Restoration was done with a hybrid composite (Heliomolar). Follow up studies, radiographically and clinically, were done every three months for a 1.5-year period. Exact Fisher and Pearson tests were used for data analysis.Results: Apical lesion was not observed in any of the radiographs. Post seal was increased by resin cement and dentin bonding agent. Post type did not significantly affect on the clinical success rate of the restorations. The retention of restoration, for both posts, was the same. Crown destruction had no significant effect on success rate. The type of anterior bite had a significant effect on success rate, as the total 6.6% failure rate was related to the patients with anterior deep bite.Conclusion: It is suggested to use metallic paraposts and bioglass posts, in extensive composite restorations for patients with deep-bite, more conservatively.

Fiber-reinforced polymer (FRP) anchors are used to prevent or delay the debonding of FRP sheets in the strengthening of structures. There are various methods to prevent or delay the debonding of FRP sheets, among them is the use of FRP anchors. In this research, the behavior of the bond between the FRP sheet and the FRP anchor after the debonding of the reinforcement sheet from the concrete surface was evaluated. Therefore, the specimens were reinforced in such a way that there is no bond between the reinforcement sheet and the concrete surface. The simultaneous increase in the ratio of the cross-sectional area and the length of the fan leads to an increase in the bond strength; therefore, the specimens with a fan length of 90 mm experience an average increase of 50% in bond strength. In this case, the failure mode was anchor debonding from the sheet. Results showed that increasing the length of the fan improved the bond strength. Therefore, the specimens with a fan length of 150 mm reached the bond strength to almost the ultimate tensile strength of the FRP composite. The amount of slip, in this case, is on average 2.5 times the specimens with a 60 mm length of fan. According to the failure mode of the specimens, the embedment depth of 50 mm has the ability to fully transfer the stress to the concrete and the anchor has not been pulled out.

Gas transmission pipelines will expand when they are put into operation under the influence of increased internal pressure and temperature. The movement due to such expansion is significant for large diameter pipelines which operate at high pressure and elevated temperature. The pipeline needs to be restrained near compressor stations in order to prevent the transmission of such movement to equipment and facilities within the station. Concrete anchor blocks are commonly used to restrain the movement of buried pipelines on both sides of compressor stations. anchor blocks for transmission pipelines are usually massive because of the high axial stress in the pipe which results in large thrust force. Current design procedures are usually based on providing an adequate margin of safety against block sliding, block overturning and soil bearing pressure.This paper presents the results of an analytical study on the response of soil, pipeline and anchor block at different operating pressure and temperatures. Nonlinear finite element analyses which include modeling of soil-pipe and soil-block interactions are carried out to evaluate the design procedures. The results indicate that the concept used in current design procedures is fundamentally flawed because it is based on controlling forces rather displacements. Furthermore, both the thrust force and the resistance capacity are grossly miscalculated. The thrust force is significantly overestimated because it is based on a fully restrained anchor. The resistance capacity of the block which is calculated based on full mobilization of the passive resistance of soil is also drastically miscalculated because only a fraction of the passive resistance is mobilized.

As the number of independent countries increases and their economies become more integrated, we would expect to observe more multi-country currency unions. This paper explores the pros and cons for different countries to adopt as an anchor the US Dollar, the Euro or the Yen. In addition, it addresses the question of how comovement of outputs and prices would respond to the formation of currency union and investigates the prospect of a Dollar, Euro or Yen currency union in the East and West Asia regions. For this purpose, we use data of 27 selected countries in East and West Asia during the period 1980-2006.Results show that the effective anchor for most of countries based on volatilities (volatility of price and volatility of output) criteria is the US Dollar.

45 patients (40 male & 5 female) with recurrent anterior shoulder instability were operated from 1993 to 2001. The mean age was 27 years (18-46) and 95% were right handed and 5% left handed. Instability was on right side in 54.4% left side in 38.6% and bilateral in 6.9%. 15 pt’s were operated with classic Rowe procedure and 30 pt’s with using modified anchor screw, and follow up period was 37.6 mounths (12-110), Bankart lesion was found in 100% of cases. Subscapularis muscle lesion, Interval lesion and capsular laxity in 9.3%, 14.5% and 47.6% respectively. Glenoid fracture and loose body in 2.9 and 29% respectively. In 75% of pt’s Hill-Sachs lesion was found that was moderate to sever type in 88%. At follow up study, First group (with no modified screw), there was no apprehension sign in 53.3% and redislocation in one patient and full range of motion in all cases. In secound group (with screw), no apprehension in 79% and no redislocation was found and range of motion was full in 93%. The first group has little or no limitation at their function in 90% and secound group in 96%. According to rowe scores, results were 53.3% excellent, 26.6% good 13.3% fair and poor in one case for first group and 69% excellent, 15.5% good and 15.5% fair without poor result in sceound group. In conclusion, using modified anchor screw for bankart procedure is easy to do, needs less instruments, with low surgical trauma, shortoperation time, and low complication rate and over all good results.

Hypothesis: adhesives and sealants based on modified silane polymer (MS polymer) are increasingly gaining market share in adhesive and sealant market place due to their desirable performance in various applications. Methods: In order to find the most optimal adhesive processing parameters, different stages of aluminum surface treatment in three stages were investigated, including the surface degreasing, sanding and priming. In this manner, the performance of four different types of degreasing agents and two kinds of silane-based primers were investigated individually. The optimum bond line thickness was also determined through adhesive joint shear strength. The effect of different degreasing agents and silane-based primers were evaluated through lap-shear strength. The effect of adhesive layer thickness was studied through lap-shear strength and cleavage strength tests. Findings: Optimum bond line thickness was determined at 0. 5 mm based on the results of the adhesive shear strength, whereas the results of the fracture toughness indicated 1. 25 mm as the optimum adhesive layer thickness. The lower adhesive strength in thicker bond lines may well be due to the possible formation of air traps and lower constrained effect of the substrate. Therefore, the least requirements for aluminum surface treatment was surface degreasing followed by sanding which results in a transition from adhesive fracture mode to cohesive fracture. The use of two kinds of silane-based primers containing the amine group, triethoxy silylpropylamine (APS) and the other with epoxy group, glycidoxypropyl trimethoxysilane (GPS) was more efficient in improving joint durability even after 2500 h cyclic aging with the more pronounced results for the APS.

Natural gas transmission pipelines transport the natural gas at elevated temperature and high internal pressure. The pipelines will expand when they are put into operation under the influence of increased internal pressure and temperature. The movement due to such expansion is significant for large diameter pipelines which operate at high pressure and elevated temperature. The pipeline needs to be restrained near compressor stations in order to prevent the transmission of such movement to equipment and facilities within the station. Concrete anchor blocks are commonly used to restrain the movement of buried pipelines on both sides of compressor stations. anchor blocks for transmission pipelines are usually massive because of the high axial stress in the pipe which results in large thrust force. Current design procedures are usually based on providing an adequate margin of safety against block sliding, block overturning and soil bearing pressure. This paper presents the results of an analytical study on the response of soil, pipeline and anchor block at different operating pressure and temperatures. Nonlinear finite element analyses which include modeling of soil-pipe and soil-block interactions are carried out to evaluate the design procedures. The results indicate that the concept used in current design procedures is fundamentally flawed because it is based on controlling forces rather displacements. Based on the results of these analyses a more rational design procedure which is based on controlling the displacements is introduced. The proposed design procedure results in a substantial reduction of the size of anchor blocks.
