Cairo’s Downtown cinemas were once masterpieces of architecture, screening golden age movies plus witnessing important events. Nowadays, few are still working, while many are ready to be demolished. The best conservation for historic buildings is managing change caused by time. One way to make this happen is smart engaging reuse, thus continue to retain value to current and future generations. Local government and private companies have tried to resuscitate Cairo’s silver screens. This revitalization started with simple face lifting, then developed to rebranding with creative re-use introducing new functions. A key to this creative re-use is across disciplines; new forms of art, music, and media performances. This paper aims to explore four re-use performances bringing the insight of art and media into the field of heritage management. First, “Nassim El Raqs” organized “When dance meets heritage” in Theatre Cinema Eldorado. Second, Radio Theatre re-used to host liveshows; “Al-Bernameg” and “AblaFahita”. Third, Zawya - located in cinema Odeon - launched as the first art-house cinema in Egypt. Last, Teatro Independent Theatre opened their interactive performance “The Metamorphosis” at cinema Elkahira. This paper ends with a framework for rebranding cinemas; comprises both the challenges facing the re-use and proposing community-oriented marketing strategy.

In this study we propose new approach for cost-effective risk reduction by developing a risk-based Safety and Performance Test Scheduling Priority Index of Medical Equipment (SPTSPIME) and a risk-based Training Strategy Selection Priority Index of Medical Equipment (TSSPIME). This study can be described as two basic phases. The first phase is to determine the factors which affect the risk and to redefine some of them appropriately for safety and performance test scheduling and training strategy selection applications. The second phase is the risk classification enhancement by considering the risk of applied energy as a new risk classification factor, describing the categories of equipment according to what is found in a real environment during eight years of work as a biomedical engineer, and scoring every category to reveal the 3 real differences between the different categories in a reasonable manner. The percentage of cost reduction by the SPTSPIME model (P1) is 59.56% of the total cost of safety and performance tests. This percentage will also influence the cost of other related extensive procedures of preventive maintenance. The percentage cost reduction by the TSSPIME model (P2) is 39.29% of the training cost.

The beginning studio sometimes described as the most traumatic period for the architecture students. Many challenges in visualizing, imagining and comprehending spatial relations over the stages of the design process have been observed. Educators confirmed that spatial ability is central to design studio demands. The main goal of this research is reducing beginners’ obstacles and enhancing design education. A total of 353 first-year architecture students were selected via random sample from three universities in Cairo. The students’ spatial ability skill-level were measured using two spatial ability test instruments. Three scores of the first design course were used in determining the students’ design performance. Inferential statistics, as well as correlation analysis and crosstab chi-square test with SPSS were employed to analyze the research data. The outcomes presented strong significant correlation at (< 0.01) points between students’ spatial ability and students’ design course performance. It has proved that spatial ability is a valid predictor of success in the beginning studio. Also, measuring spatial ability helps to identify students who are not ready for studio requirement. Findings suggest enhancing students’ spatial ability among the all preuniversity education levels and during the preparatory year course subjects. This will increase the probability of success.

Egypt is facing a huge financial problem reflected on the difficulty of funding public projects either in construction and infrastructure sectors. One of the approaches for such problem is to work cooperatively with private sectors in the form of PublicPrivate Partnership Projects (PPP). This approach, however, is facing a number of challenges. This paper, thus, aims at providing a factor analysis for the establishment of PPP in Egypt through extracting lessons learned in other countries. A literature review has been done to analyze existing factors, followed by a qualitative study of case studies. Finally, a survey questionnaire was conducted on a purposeful sample of 55 stakeholders, either from private or public sectors in order to prioritize and verify factors affecting the success or failure of PPP projects in terms of their severity and impact in Egypt. Results of this paper indicated that bureaucracy, corruption, poor enabling policies and inefficient feasibility studies are among the major barriers that face PPP in Egypt, whereas achieving a reliable contractual structure and political support are the main potentials. Findings of this paper are valuable to stakeholders, decision makers and policy makers in Egypt, as it could guide their thinking towards achieving successful PPP Projects.

The continuous growth of motorized vehicles and air pollution caused by them, are among the major reasons in which strategies related to transportation and land uses are being implemented enhancing the built environment. This paper introduces approach leading catalytic effects for urban redevelopment through introducing Mobility hubs. According to academic arguments regarding the relation between urban form, built environment and travel patterns, the more urban development around transit stations referred to as transit oriented development (TOD) is compact, the more it contributes to sustainable metropolitan system. Mobility hubs are types of TOD projects, which strive to create opportunities for development. The current research examines the possible role of mobility hubs as anchors in urban regeneration strategies aiming to formulate a model that evaluates hubs' effects on surrounding contexts‘ regeneration. This research is divided into two parts; the first examines the concept of mobility hubs as catalysts to existing urban areas‘ regeneration, the dimensions and elements responsible for the hubs' success as catalytic projects, the second investigates case study for transit station and its context, in Alexandria city, Egypt. The analysis of this case will be through designed model assessing the catalytic effect of the hub on its immediate contexts of value.

The research addresses the concept of dynamism and movement in architecture; also the role of time, the human's eye, and perception to classify it “latent or movement”. In addition, analyzing international projects about the thought of dynamism, and employing the vocabulary of the formation. Because of the thought of some architects in the static of the building, which gives the feeling of boredom. In addition, fixed forms are no longer able to meet the needs of users, especially with the increasing of climatic changes and advanced activities. Besides, the misconception that dynamism is only to move the building without looking for the architectural thought behind it, which depend on definite rules and the designer's experience and practice. Therefore, the aim of the research is to guide and employ the concept of dynamism in design, what governs it from the architectural thought to be interactive dynamic buildings by concluding and formulating a methodology to link and reconcile among opportunities of movement, technology “systems – materials”, the required performance, and the factors affecting. Moreover, determining any types of movement more properly and suitable for the nature of the project to root the concept of dynamism, and to give the building an architectural character.

Cities are the arenas for all human activities, by the middle of this century they will be home to 65 percent of the world’s population, meanwhile they face multidimensional challenges regarding how to balance the needs of its population growth and the environmental requirements, in other words, to be both livable and sustainable cities. Thus, this study argues that urban interventions that based on innovative tools contribute to both sustainability and livability in cities. Innovative urban interventions can contribute positively in the city long-term planning, they represent incremental planning initiatives that seek to regenerate the urban tissue, as well as the study argues that this type of interventions encourages the community engagement in decision making and funding the regeneration plans, moreover it works in harmony with the environmental requirements. This study investigates the potentials of urban interventions in supporting city's livability and sustainability, also to set a broader definition of this type of urban interventions that based on innovative urban tactics. The study based on an analytical study of two practical cases, the findings represent lessons from practice, which reveals how innovative urban interventions have efficient impact as a regeneration approach that boosting both livability and sustainability of the city.

The aim of this paper is to evaluate the performance of three surface water treatment plants using different filtration technologies. The performance evaluation was based on variations in turbidity, total dissolved solids “TDS” and total solids “TS” as well as micro-organisms counts in raw and filtered water in addition to an economic comparison between the studied treatment processes with different filtration systems following an evaluation of collected data along four years from existing water treatment plants “WTPs” in Menofia Governorate. The main conclusions of results revealed similar performance in removal of turbidity, microorganisms and TS concentration through various filtration systems. Direct filtration system with a declining rate was considered the most economic in operation. The results also indicated that conventional filtration system stands in an intermediate position in terms of economic comparisons. Although pressurized compact filtration system recorded efficiencies same as other systems in terms of removal of turbidity and microorganisms, the system was the least favored in economical comparisons under the studied conditions “e.g. flow, water quality, consumables”.

Local scour around bridge piers and abutments, induced by hydraulic deficiencies, is the major cause of bridge failure. Most of the available empirical formulae have been developed based on experimental laboratory tests using uniform sand. However, the bed sediment in the field is to some extent graded. To develop a more reliable formula, well graded sand was used in the experimental flume of this study. In the present paper, the local scour depth around exposed single pile founded in sandy soil was studied experimentally in the laboratory to predict its maximum value. New scour depth prediction equations were developed and compared with some of the previous published equations, other researcher's data, and field data and they were found in very good agreement with them. For complete definition of the scour hole geometry, new equations were developed to estimate the scour hole width at different locations around the pile, thus helping in introducing protection measures for the scour hole. The developed equations are applicable for both clear-water and live-bed scour cases.
