The impact of the collapse of the Soviet Union on Libya foreign policy during the period from 1991 to 2003
One of the most notable events in world politics in the second half of the 20th century was the Soviet Union’s fall in December 1991 which profoundly changed the outlook of the global political scene and the balance of power among its key actors. This thesis studies the impacts and significance of the Soviet demise on Libyan foreign policy between 1991 and 2003. Libyan foreign policy was transformed; the thesis asks how, why and when this occurred and how the changes in foreign policy were managed. While so doing, a set of questions are raised concerning the emerging context and developments in world order which seemed to compel Libya to change its behaviour, changing its relations with the West in general and the United States in particular. Three major questions are explored in detail in this thesis. The first question relates to how and why Libya aligned with the Soviet Union. The second question addresses how and to what extent these developments in international order appeared to have affected Libya’s foreign policy behaviour. Finally, the third question sheds light on the reasons and attitudes that led to these changes in Libya’s foreign policy orientations. This is also to engage with an important literature on the scope of foreign policy of small states. It also raises questions of the role of leadership, the continuing post-Soviet relationship between Russia and Libya, the decision making processes in Libya, and the agent-structure question in international relations as it bears on the forces which brought about change in this case
Improving the Estidama Rating for New ADEC Prototype Schools by Renewable Energy Integration Joud Abdalla Al Jumaa Al Dakheel
The building sector in the United Arab Emirates (UAE) has experienced a tremendous expansion in the last forty years due to population growth and economic development. Presently, the UAE has one of the world’s largest energy consumption per capita, with the building sector accounting for 70% of the consumed energy. In the last decade, the government intensified its efforts to implement stringent environmental regulations and schemes by mandating environmental policies and regulations. It introduced “Estidama”; the local sustainability framework, and the Pearl Building Rating System (PBRS) to promote the development of sustainable buildings. All governmental buildings must achieve a minimum of 2 out of a maximum of 5 Pearls. Among these, schools are dominant in numbers and target the dual intent to create a sustainable as well as a healthy learning environment. In this regard, Abu Dhabi Educational Council (ADEC) has targeted all new schools to go beyond the requirement and reach 3 Pearls by planning to build 100 new schools from 2010 to 2020. Presently, 53 schools had been built. However, only 10 of the built schools have achieved the desired target.
The objective of this research is to investigate the opportunities of enhancing the performance of ADEC schools that did not achieve the targeted Estidama level through a representative school prototype. Hence, an analysis of the Estidama performance of the school was carried out to identify the opportunities of enhancement, which showed a gap within the renewable energy systems. Next, a transient simulation tool TRNSYS, was used to assess and predict the performance of three renewable energy systems namely Photovoltaic System (PV), Solar Powered Absorption Chiller and Geothermal System. These systems were selected based on a literature review done to show their effective performances. Several parameters were optimized in each system to reach optimal performances. The photovoltaic system was sized to achieve 10% of the annual energy consumption and the solar absorption chiller targeted a cooling demand reduction of 10%. The geothermal system was sized to reach optimum values of delivered energy and outlet temperature of the ground heat exchanger. Finally, a simple payback period was done on the three systems to determine the economic feasibility of renewable energy in ADEC schools. Key findings revealed that the PV panels achieved the targeted 10% of the annual energy consumption producing 208849.32 kWh annually. The optimized solar absorption chiller system showed 19% annual cooling savings and 7.2% savings from the overall energy consumption of the school. The geothermal system findings implied 2.2% from the total energy consumption and 5.8% from the annual cooling consumption. The three renewable energy systems have shown collectively 19% savings of the annual energy consumption. The simple payback period for PV and solar absorption chiller was 3.5 years and for the geothermal system was 8 years. The proposed school design increased the credits of the school by 14 additional credit points and reached the targeted 3 Pearls. Finally, these results augur a great potential in integrating renewable energy systems in future ADEC schools for an improved energy performance
Some Results on Pure Submodules Relative to Submodule
Let R be a commutative ring with identity 1 and M be a unitary left R-module. A submodule N of an R-module M is said to be pure relative to submodule T of M (Simply T-pure) if for each ideal A of R, N?AM=AN+T?(N?AM). In this paper, the properties of the following concepts were studied: Pure essential submodules relative to submodule T of M (Simply T-pure essential),Pure closed submodules relative to submodule T of M (Simply T-pure closed) and relative pure complement submodule relative to submodule T of M (Simply T-pure complement) and T-purely extending. We prove that; Let M be a T-purely extending module and let N be a T-pure submodule of M. If M has the T-PIP, then N is T-purely extending
S-maximal Submodules
Throughout this paper R represents a commutative ring with identity and all R-modules M are unitary left R-modules. In this work we introduce the notion of S-maximal submodules as a generalization of the class of maximal submodules, where a proper submodule N of an R-module M is called S-maximal, if whenever W is a semi essential submodule of M with N ? W ? M, implies that W = M. Various properties of an S-maximal submodule are considered, and we investigate some relationships between S-maximal submodules and some others related concepts such as almost maximal submodules and semimaximal submodules. Also, we study the behavior of S-maximal submodules in the class of multiplication modules. Farther more we give S-Jacobson radical of rings and modules.

Design and Implementation of No Load, Constant and Variable Load for DC Servo Motor
Simulations were conducted to improve and design an appropriate control system and obtain a model with the required development to suit the operation of the engine with constant and variable loads, which are the proposed working conditions that are suitable for many applications. The current simulation aims to build and design a model for an electric motor (DC Servo motor) and a model for a conventional controller (PID). The proposed model addresses the cases of fixed and variable loads in terms of using the controller that improves the performance of the motor’s work for different conditions. Three cases were developed to conduct the proposed tests, which included the case of no-load, fixed and variable load. Tests were conducted. Without the console and for the purpose of comparison and observation of improvement, the test was conducted with the addition of the console. The results showed system performance may improve depending on usage using traditional control systems. Performance measurement criteria are adopted for the purpose of comparison and observation of performance improvement. The criteria that are adopted are rise time and stability (steady state) in addition to the ratio of the rate of under and over-shoot. Where it can be deduced from this the possibility of using different control systems, including traditional ones, to improve performance, and they include controlling the speed of the motors, as well as controlling the effort, and the consequent effects on the subject of the study, as it deals with transient cases and changing operating conditions with more than acceptable efficiency and relatively high quality. There are four state simulation include, 1st at no load without controller: rise time equal 309.886ms , overshoot equal 44.203% and undershoot equal 9.597%.2nd at load without controller: rise time equal 216.319ms , overshoot equal 58.654% and undershoot equal 0.210%.3rd at no load with PID controller: rise time equal 1.177s , overshoot equal 0.505% and undershoot equal 1.914%.4th at load with PID controller: rise time equal 1.112s , overshoot equal 0.509% and undershoot equal 5.856%

The impact of TQM on a traditionally segregated work environment: An empirical study of the healthcare sector in the Kingdom of Saudi Arabia.
In the last decade, the rapid development in the Kingdom of Saudi Arabia (KSA) has forced its government to implement modern management styles such as Total Quality Management (TQM) to ensure continuous improvement in the provision of healthcare. There is a considerable body of literature that shows the benefits of implementing TQM in hospitals, but there are few empirical studies that show TQM implementation efforts in the healthcare sector. Furthermore, the healthcare literature did not explore the implementation of TQM in a context of gender segregated environment such as the case in KSA. This research project is an exploratory investigation assessing the impact of TQM in a gender segregated healthcare environment such as KSA. The research design used triangulation methods to investigate the problem at hand. A combination of quantitative and qualitative methodologies were used through field-work and external comparisons. The approach was based on the following: (1) Assessing the level of perception and understanding of TQM principles in several KSA hospitals, taking into account the differences and similarities between the different gender population, (2) Examining the approach to TQM implementation and its degree of effectiveness in four Saudi hospitals to highlight critical factors for effective implementations using the Baldrige assessment method; (3) Benchmarking the Saudi hospital experiences to UK and USA hospitals to highlight key facilitating and inhibiting factors; (4) Using key findings from the previous steps to identify the critical factors and propose a model for TQM implementations in a segregated healthcare environment such as the case in the KSA. The survey research findings show a weak appreciation, awareness and understanding of TQM in managing healthcare organisations by the respondents in the KSA. It clearly shows that many employees in the organisations do riot understand TQM. The degree of emphasis for each quality activity varied and thus more research needs to be done to investigate the importance of each quality activity to a TQM implementation process, as there are varying degrees of emphasis across the board. The KSA case studies show that in implementing organisations, TQM intentions and TQM policy frameworks are generally acceptable. However, the implementation process is generally weak and lacks coordination in the majority of these organisations. It is clear that the majority of the KSA cases have not succeeded in total commitment towards a total quality culture. When compared to the UK and USA hospitals, the majority of the KSA cases show deficiencies in most of the critical activities that form the foundation of a successful quality process. Furthermore, the study indicates three critical factors in KSA hospitals that either did not exist or were not given full attention. The importance of these factors were further validated in the literature. The factors were continuous top management commitment, continuous education and training, and culture awareness. These factors were then used to develop a model for TQM implementation for a segregated healthcare environment.King Saud Universit
