“Egypt in the Arab Spring: Multidisciplinary Research Perspective”
London School of Economics, London, 28 September 2012Uprising of Islamic dimension is the most important trait of political life post the Arab revolutions especially in Egypt and Tunisia. A great debate among political intellectuals focuses on its reasons and its impact on the long term inside the Egyptian and the Tunisian societies; is it an imposed or a selected alternative of the secular regime?. Parliamentary elections in Egypt (The Freedom and Justice Party "Ḥizb Al-Ḥurriya wa Al-'Adala" and The Light Party "Ḥizb Al-Nūr") and Tunisia (The Renaissance Movement Party "Hizb an-Nahḍah"), and presidential elections results in Egypt proved that is the people choice which arises the following research problem
Validated Stability Indicating Assay of Linezolid by Spectrophotometric and High Performance Liquid Chromatographic Methods
No full textSimple, precise and sensitive methods have been used for the determination of linezolid and its alkaline induced degradation product and in pharmaceutical dosage form. The first method depends on differential derivative spectrophotometry that is based on inducing spectral changes upon changing pH of the medium. In this method, ∆A values have been measured at 227.2 nm and Beer's law was obeyed in concentration range of 2.0-14.0 μgm1-1. Another three methods based on derivative spectrophotometry including D2, D3 and D4 were proposed in which the derivative amplitudes were measured at 260.9 nm, 252.0 nm, 245.6 nm respectively. The calibration curve was linear over the concentration range of 1.0-14.0 μgm1-1 for these methods. The fifth method depends on reversed phase high performance liquid chromatographic method (RP-HPLC) that was successful in the resolution of linezolid and its alkaline induced degradate using ZORBAX- C18 column and a mobile phase of KH2PO4 buffer adjusted at pH 3.0 : methanol: acetonitrile in the ratio of 60:20:20 (v/v/v). A linear response (r2=0.9998) was observed over the range of 2.0-24.0 μgm1-1. The retention times of linezolid and its degradate were 2.973±0.008 & 1.464±0.118 respectively. All methods were successfully applied to the commercial pharmaceutical preparation without interference from common ingredients accompanying the drug

This indispensable companion to Norbert Lechner's landmark volume Heating, Cooling, Lighting: Sustainable Design Methods for Architects, Third Edition completes the author's mission to coverall topics in the field of sustainable environmental control. It provides knowledge appropriate for the level of complexity needed at the schematic design stage and presents the most up-to-date information available in a concise, logical, accessible manner and arrangement. Although sustainability deals with many issues, those concerning energy and efficiency are the most critical, making an additional goal of this book one of providing architects with the skills and knowledge needed to create buildings that use electricity and water efficiently. Guidelines and rules-of-thumb are provided to help designers make their buildings use less energy, less water, and less of everything else to achieve their primary objectives.
In addition, this book:
Addresses ways to reduce electricity usage through more efficient lighting systems and appliances and by incorporating automatic switches and control systems that turn off systems not in use.
Covers the design of well-planned effluent treatment systems that protect against potential health hazards while also becoming a valuable source of reclaimed water and fertilizer
Provides coverage of fire protection and conveyance systems, including very efficient types of elevators and escalators and designs that encourage the use of stairs or ramps.
Complete with case studies that illustrate how these systems are incorporated into large-project plans, Plumbing, Electricity, Acoustics is an indispensable resource for any architect involved in a sustainable design project

Computer analysis works to solidify and extend the creative idea or concept that might have started out as a sketch on the back of an envelop
Corporate Social Responsibility (CSR) and its Role in Sustainable Development : Case Studies and Lessons Learned
No full textCSR is a multidisciplinary concept that defines the new responsibilities of businesses in societies. It is the manifestation of the implicit contract between businesses and societies that entails that there is a mutual benefit between them. The debate on the responsibilities of businesses towards societies has existed since businesses existed. However, it gained momentum in the 20th century with the emergence of large businesses with unsuitable practices towards the people and the environment. Hence, several civil movements appeared to face those businesses and demand the rights for the people and the society, meanwhile, scholars started to develop a formal conceptualization of CSR.
Although the responsibilities of the firm are still debatable and unspecified, there is a general consensus that those responsibilities encompass that businesses achieve profits while obeying the law. CSR demands more, as it looks beyond the economic and legal responsibilities towards the ethical and discretionary responsibilities of businesses; it questions how businesses impact their stakeholders both internal and external while giving back to the society.
According to the sustainable development approach in explaining CSR, CSR is a tool for achieving sustainable development; different schools explain how governments as regulators and facilitators, the civil society as a watcher and helper can help businesses partake in fulfilling societies’ needs. Businesses themselves have an interest in participating in development. Accordingly, the role of governments, civil society, and businesses in promoting CSR as a tool for development is inevitable. Businesses especially MNCs are aware that they need social acceptance in order to operate, large MNCs spend years to build their brands and market it all over the world, this brand image and reputation are vulnerable, and hence, businesses cannot afford to jeopardize them by practices that societies deem as irresponsible. This realization by businesses led them to start factoring in society’s views and opinions as an important factor in their decision making process. Nowadays, businesses know that consumers are aware of everything related to their products from production to retail and when they take a decision to consume; this decision contains an ethical part that will not accept any irresponsible act by the company. Hence, businesses are trying to behave in a social responsible manner in all aspects of its operation. Thus, CSR serve as a key to gaining social acceptance for businesses while fulfilling society’s demands. It serves both parties by assuring that they both get what they want

A QoS – based framework for Efficient Web Servers
No full textThis research work contributes to research aiming to improve the QoS of commercial web servers. The QoS is defined in terms of server throughput and service time as perceived by users. The work is a two-part approach. The first part is concerned with
load balancing of web traffic, while the second tackles admission control for the server itself. The contribution is as follows: we elaborated the session-based admission control by introducing the server cluster utilization as an internal control parameter for the number of accepted sessions, besides the traffic burstiness as an external parameter and studying in detail the variability of the number of the completed sessions with system parameters.
We could prove the usefulness of the emerging trend of combining load balancing with admission control for commercial web servers. For load balancing we used content-aware load dispatching policy: Distributed Workload-Aware Request Distribution (DWARD) and for admission control we have used adaptive time slot scheduling predictive session based admission control, where the length of the execution intervals of the algorithm depend on the burstiness arriving to the system. Via a simulation model, we could show that a web server cluster augmented with load balancing and session-based admission
control performs better in terms of QoS than a server without these controls. We could also show how the throughput and service times of the server cluster are tradeoffSupervisors Prof. Salma Ghoniem ; Dr. Sahar Haga
