The association between client qualities and design team attributes of green building projects
Journal ArticleThe construction industry has become more complex due to changes in technology and the greater emphasis placed on satisfying green requirements. The design phase is the most important phase in determining the green performance of building projects. The performance of the design team is crucial. The selection of a design team should be based on a set of criteria. Therefore, a competent design teams is required to have a good understanding of environmental issues. Design teams require a range of competences such as skills of environmental assessments, initiatives and environmental background as the basis for design decisions. In addition, success of building projects greatly depends on the client’s performance. The performance of clients is crucial since decisions made will influence the overall project performance. The quality of clients’ representatives has potential influence on design team performance. In designing green buildings client’s attributes are critical factors to high performance of building projects. The propose of this study to identify the significant associations between variables of design team attributes and client qualities. To achieve mentioned aim a questionnaire survey was conducted to collect data required. A sample of 274 respondents has been covered under the study, including architects and engineers practicing design and consultancy building sectors. Prior to analysis of data WINSTEPS software were used for Rasch modeling to determine validity and reliability of date. Descriptive analysis data includes quantitative and qualitative. The results indicate that the influence of Clients’ Qualities on Design Team

A Framework for Successful TQM Implementation and Its Effect on the Organizational Sustainability Development
Journal ArticleThe main purpose of this research is to construct a generic model for successful implementation of Total Quality Management (TQM) in Oil sector, and to find out the effects of this model on the organizational sustainability development (OSD) performance of Libyan oil and gas companies using the structured equation modeling (SEM) approach. The research approach covers both quantitative and qualitative methods. A questionnaire was developed in order to identify the quality factors that are seen by Libyan oil and gas companies to be critical to the success of TQM implementation. Hypotheses were developed to evaluate the impact of TQM implementation on O SD. Data analysis reveals that there is a significant positive effect of the TQM implementation on OSD. 24 quality factors are found to be critical and absolutely essential for successful TQM implementation. The results generated a structure of the TQMSD implementation framework based on the four major road map constructs (Top management commitment, employee involvement and participation, customer-driven processes, and continuous improvement culture).

JOINT MOMENT-ROTATION CHARACTERISTIC IN LIGHT OF EXPERIMENTAL SIMULATIONS OF FRAME COLUMN LOSS
Conference paperAspects related to robustness of steel frameworks with semi-rigid steel and steel-concrete composite joints are dealt with. Experimental investigations were carried out for sub-frames fabricated in technical scale. Pushdown tests for steel subframes simulated the joint ability to transfer the bending moment and axial force under a column loss scenario. Tests on composite sub-frames were arranged in two stages. The first one was related to a service stage when the slab was under a gravity load and the column to be removed supported. The gravity load was sustained in the second stage when a column loss scenario was simulated. Experiments have shown that composite flush end-plate joints may not be robust enough since their low strength under sagging bending, despite of good ductility, does not allow for the redistribution of internal forces in order to achieve the equilibrium in the residual state after static column removal. Contrary, symmetrical steel and composite joints with extended end-plates on both sides of beam flanges seem to be more robust, despite of their lesser ductility. Robust bending behaviour is possible because extended end-plate joints exhibit a better balance between the strength and rotation capacity that allows to achieve the equilibrium state in case of a static column loss event.

ANSYS-FLUENT VALIDATION FOR TRANSONIC FLOW OVER ONERA-M6 WING AT DIFFERENT ANGLES OF ATTACK AND MACH NUMBERS
Conference paperAbstract –Wings are the main lift generating sources for any aerospace vehicle. The performance of an airborne vehicle largely depends on its wing design. That is why it is important to understand and be able to calculate wing characteristics in every design process. The analysis of the 3 dimensional transonic flow over ONERA M6 wing at two Mach numbers and angles of attack from 0 to 6 degrees and operating Reynolds number of 11x106 is presented. Computational Fluid Dynamics CFD as a widely used analysis and design tool still need to be validated by comparison with experiment. Ansys/Fluent is used to solve the governing equations with k-SST turbulence model. The validation is done through comparing pressure coefficient distributions over wing surfaces at seven span locations, with experimental measurement . Wing geometry is successfully modeled inside Ansys geometry modeler and unstructured mesh is generated with Ansys mesh modler. Results show good agreement with experimental data at Mach number of 0.84 and 3 degrees angle of attack. On the other hand, as Mach number and angle of attack are increased, numerical results show poor accuracy in capturing shock wave position.

Critical stress for cleavage fracture in continuously cooled medium carbon V-microalloyed steel
Journal ArticleCleavage fracture of the medium carbon V-microalloyed steel with structure consisting of acicular ferrite, pearlite and grain
boundary ferrite has been investigated by means of four-point bending of the notched samples at -196°C. It was found that
cleavage fracture initiation has not been related to the coarse second phase particles cracking. Calculated values of the effective
surface energy of 49 J/m2 and critical cleavage fracture stress normalized by yield stress of 1.84 are in agreement with the results
for the steels with ferrite-pearlite and bainite structures.

Investigating the total quality elements based on Deming management model in oil industry in Libya–an empirical study
Journal ArticleThe purpose of this paper is to investigate the quality management dimensions, based on Deming Management Model, in Oil industry in Libya. Questionnaire, semi structured interview and open interview were used to collect data from random sample of 42 qualityrelated managers from the Libyan Oil industry. Forty-five questionnaires were provided by hand to quality-related managers from the Libyan Oil companies. A total of 42 were returned sufficiently completed, that gave us a response rate of approximately 93.33%. The regression analysis indicated that these organizations implement total quality management practices. The findings suggest that an integrated approach is required to implement the total quality management practices in order to realize strategic quality objectives. This research is subject to the normal limitations of survey research. The data is based on individual opinion of quality related managers, which may bring in some bias. Further research needs to be done to advance our knowledge and to further support the findings. For instance, a larger sample size and more items per Deming principle may be used in future studies to duplicate these results and to increase the internal consistency of the scales. Deming Management Model is applied to one industry in this study. Therefore, to establish the generalization of the Model within the context of Libya, it needs to be tested in other industries setting, both in public and private sectors. The study extends the applicability of the Deming Management Model to a new industry and country. Collectively, the results of the research provide more understanding of issues relating to quality management in developing countries and a framework for enhancing organizational effectiveness. Therefore, the research can make a useful contribution.

التغير الاجتماعي مبادئ ونظريات
كتابيتناول العديد من الموضوعات في التغير الاجتماعي، بصورة سلسة وفي متناول فهم الجميع خاصة طلاب قسم علم الاجتماع، فيقدم مفاهيم التغير الاجتماعي، وعوامله ومعوقاته وأنواعه وملامحه .. حيث تعتبر ظاهرة التغير في هذا العصر من أهم المسائل التي تشغل الفكر الاجتماعي الحديث, وخاصة في العقود الأخيرة, فقد أخذت الجهود تتجه نحو التغيير المخطط من أجل تنمية حقيقية هادفة. ويعتبر مصطلح التغير الاجتماعي مصطلحًا حديثًا نسبيًّا بوصفه دراسة علمية، ولكنه قديم من حيث الاهتمام به وملاحظته. ولقد تطور مفهوم التغير الاجتماعي مرورًا باتجاهات ومراحل متعددة، تعددت معها المفاهيم والمصطلحات المشابهة لهذا المفهوم، والمتداخلة فيما بينها إلى درجة كبيرة. فالتغير الاجتماعي يصيب البناء الاجتماعي, أي يؤثر في هيكل النظام الاجتماعي في الكل أو الجزء, وهو الذي يحدث أثرًا عميقًا في المجتمع, و الذي يطرأ على المؤسسات الاجتماعية كالتغير الذي يطرأ على بناء الأسرة, أو على النظام الاقتصادي أو السياسي وما إلى ذلك, هذا التغير هو الذي يمكن تسميته بالتغير الاجتماعي
