This paper was aimed to examine the removal of oil from water by photocatalytic advance oxidation under solar light. A pH of 11 has shown a higher oil removal efficiency. Oil remove efficiency levels at pH 11 have been found 75% within 230 minutes’ oily water effluent, studies have shown that Langmuir isotherm has been the best-fit one of the isotherms for the removal of oil. Data have shown a higher adsorptive capacity. Also we have studied another parameter like (catalyst concentration, initial oil concentration and pH). While the treatment of waste-water is dependent upon a great level of quality for the processed industrial water, the nature of wastes that are added throughout the utilization, and the treatment degree that has been received by the waste-water. Then, the data of the waste-water quality that has been measured routinely and it was reported at the plants of the waste-water treatments are mainly for disposal of the treated effluent or the necessities of the discharge in terms of the gross pollution parameters.

Previous knowledge has shown a concept revealing different boundaries and relations of building spaces with its outer shell; which represent the boundaries of these spaces. This concept is called interstitial space which is based on creating an interlocution and communication within this space giving a new understanding of meaning and a new approach in architectural formation. This concept of knowledge description has varied as it is linked once to its nature or again to the built environment levels whether it’s architectural or urban diverged within the academic and social context, as well as the blurring relationship nature of this space with the structural system of the building. Therefore, the problem state of this research, which goal focuses on, is highlighted as “the urge to investigate the concept of interstitial structure characteristics”. Yet the methodology of the research is based on the descriptive and analytical approach consisting of three phases; phases one is to build a theoretical framework about the characteristics of the interstitial space in architecture; second is to conduct a practical study and identify several samples of buildings vary in their structural systems (traditional, structural and space); then analyze data and identify the conclusions of which the interstitial space grows and expands physically and expressively with the presence of the recent constructive systems and the lack of presence of the Interstitial spaced has led to spatial differentiation and closed toward inside especially those designed parametrically and reflect it in the other traditional and structural constructive systems.

Distance learning is something really familiar nowadays. In the past few years, our world has witnessed a massive revolution in the world of information technology and provided simple ways to obtain information at reasonable prices. Today, sharing information is an integral part of every person’s life. Devices such as phones, tablets, and smartphones have become the main focus of digital life. With technological progress, electronic devices go through stages of software development that allow them to perform additional, more complex tasks, and process a larger flow of information. Almost everyone between the ages of 10 and 60 owns a mobile device. So mobile apps are always up to date. Therefore, it is quite logical to use the mobile application as an auxiliary element in the educational system, especially as it provides many services such as accessing the Internet, browsing the web, sending e-mails, exchanging multimedia messages and files and providing instant messaging applications with audio and video. Focusing on employing technology in education and its curricula, regardless of its level, is considered very important. This work diagnoses what users prefer when using the e-learning application through a questionnaire distributed to a group of university students to collect data on their preferences regarding mobile applications for e-learning.
