Cities pass through several transformations during their stages of development, the most influential was the one that accompanied the industrial revolution and modernity, resulting in scattered structures, functional requirements and industrial activities that affected cities spatially. The advancement of knowledge, technological development, innovation, and industrial progress in the post-industrial era had a great impact on the adoption of more technological applications in conjunction with the global transformations and globalization, this has resulted in the phenomenon of neglected buildings. which has been reflected in buildings, structures, industrial zones, and the quality of urban fabric, and its scene, from which the problem of research was identified as "lack of cognitive perception showing the impact of neglected buildings on the urbans cape ". In order to address the research's problem, a comprehensive theoretical framework was developed for the concept of abandoned buildings, the main reasons, levels of abandonment, and neglect in general. The most important suggestions the impact the quality of the urbans cape, in particular, The research has reached special conclusions, recommendations, procedures and requirements for the owners of buildings to achieve and reduce its negative impact on the urban-scape.

"Historically, the flexural behavior of hybrid fiber cement composites is not completely understood using the traditional test methods. This research presents the results of an experimental investigations on a high performance cement composites (HPCC) containing both micro steel fibers (SF) and micro polypropylene fibers (PP) before and after elevated temperature exposure. The experimental program was developed to study the flexural performance (flexural strength, toughness and stiffness) under high temperature using mono and hybrid (SF) and (SF + PP) fibers. Mixtures were divided into eight different groups, with constant w/c of 0.28 and different fibers content. Based on the results of this research, the replacing of micro (SF) in high performance cement composites by 15 % of micro (PP) fibers is recommended at high temperature exposure due to the fact that all hybrid fiber HPCC specimens show slight decreasing in flexural behavior compared to samples reinforced with 1% volume fraction of mono steel fibers after high temperature exposure."

Cathodic Protection (CP) is an effective method to reduce the corrosion of metallic structures that submerged in water or buried in soil. In order to reduce the corrosion of any structure, the voltage between the metal to be protected and a reference electrode must be controlled on a preset level called the full protection level. In this paper, a boost converter circuit and L298N integrated circuit were used as a control system to regulate the protection voltage on a preset identified range. The boost converter has been used to raise the supply voltage, while the L298N circuit has been used to regulate the boost converter voltage automatically by adjusting the duty cycle through the Arduino microcontroller. Before the designing and implementing of the proposed controller, the effect of some different factors should be studied to understand the nature of the system and determine the controller voltage and current ranges. These factors are: The solution temperature, The dissolved oxygen, the anodecathode distance and the power of hydrogen. The photovoltaic array was employed to impress the electrical current to the system. However, the protection voltage should be kept between 0.8 V and 1 V. Therefore, the control circuit will change its output voltage automatically to return to the mentioned range. ARTICLE INFO Received: 07/01/2018 Accepted: 29/11/2018
