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.

In addition to calculating the water quality index (WQI) for each station and comparing it with the classification (Bhaven, 2011). The study was conducted on ten water supply stations (Najaf, Al-Koufah, Al-Hira, Al-Manathrah, Al-Huraira, AlHaidariyah, Abbasiyah, Al-Old and new Al-Mashkhab, and Al-Qadisiyah projects). The nine variables are PH, Turbidity, Calcium, Magnesium, T.D.S, Sulphates, Total Hardness, CL and Alk, for two consecutive years from December 2015 to August 2016. The results showed that most of the physical andchemical factors that were studied were tended to decrease after the liquidation process. The raw water was its variables showing a clear increase, especially the total hardness, especially in the very hot months of July and August. In general, it can be said that most of these factors located within the limits of the standard specification of Iraqi allowed for drinking water except (turbidity and dissolved salts and total hardness) that exceed the specifications in some months.In terms of water quality index (WQI), the results showed that (Good Water) for all stations according to the classification of Bhaven except the New Mashkhab station is (Excellent Water). *Corresponding author: E-mail addresses:Eng.zahra.abd@uobabylon.edu.iq ©2018AL-MuthannaUniversity.Allrights reserved.

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.
