The purpose of this work is to eliminate as much as possible. Most of the problems caused by using polyethyl metha acrylate alone are the addition of titanium granules of different sizes. In&nbsp;act out&nbsp;to&nbsp;end&nbsp;a&nbsp;passable&nbsp;and&nbsp;identical&nbsp;direction&nbsp;of Ti&nbsp;sods&nbsp;in the polymer&nbsp;influence, mixer milling process was applied. The study is conducted in the preparation of samples of PMMA with micronized titanium granules at( 0%, 0.5%, 1% , 1.5%), and other specimens of polymer are reinforced with titanium nanoparticles and in the same proportions. The tests are carried out to determine the validity of the composite material for use, the results are obtained from the tests of impact,and tensile testing where the specimens are reinforced with nanoparticles whose mechanical properties are (6&nbsp; J/mm<sup>2</sup>,5.5MPa) the highest percentage of titanium nanoparticles, Corrosion rate decreased from(0.677 to 0.0015) a percentage (14.77% ) ie&nbsp; give the highest and best results.</p> Baraa H.

The models were‏ applied to annual water discharge for Diyala river. The water discharge magnitudes computed for many return periods‏ . Firstly, The models were Compared using different statistical measures " bias, standard error and root mean square error. The Chi-Square test was used to evaluate the goodness of fits for these models. According to this test and using the aforementioned measures, the Log-Normal III&nbsp; distribution could be taken as the best for the water discharge series. This type of model is useful for designing the dam or spillway by computing the magnitude of water discharge flood versus different return periods.</p> Wisam A. Abidalla Ahmed S. Naser Ali H.

Losing the clarity of its identity as an Islamic architecture because sustainability solutions may have a profound impact on the overall shape of the mosque where it represented the particular problem of research, and the research problem was defined by Cognitive impairment in the impact of the concept of sustainability on the clarity of&nbsp; identity in Islamic centers. Because the importance of Islamic centers in the definition of the Islamic religion, especially in the West. The aim of the research is to reach the design and technical principles recommended to be used in the architecture of contemporary Islamic centers to serve the achievement of sustainability in all its aspects without covering the features of its identity as Islamic architecture.The hypothesis of research (high-tech solutions to achieve sustainability affects the clarity of the identity of Islamic centers). The research methodology adopted a conceptual framework of knowledge to address the definitions of the concepts of sustainability in architecture in general and the definition of mosques and the identity of Islamic architecture as well as analysis and devise sustainability solutions through examples of traditional and contemporary mosques, also criticism of previous studies that addressed these concepts of sustainability and the identity of mosque architecture ,and then build the theoretical framework and extract the main and secondary&nbsp; variables, and then the practical part, which addressed elected samples of Islamic centers (global and Arab) to reach the final conclusions and recommendations. The most important research reached is the possibility of using high-tech technologies to achieve sustainability in the construction of Islamic centers without blurring the features of its identity as Islamic architecture, and the need to emphasize the clarity of the Islamic identity of sustainable Islamic centers as a pride in the Islamic faith and the historical legacy of the ancient mosque architecture. Variables of its theoretical framework as design / technical criteria preferred to be taken into account in the design of contemporary sustainable Islamic centers characterized by the clarity of its Islamic identity.</p> Mahdi Saleh A.H.

Thus, the Islamic religion, with its intellectual and practical dimensions, is the main effective of architectural products in form and substance. Islamic legislation represents the practical aspect. Each society has its own culture, customs and traditions. Therefore, Islamic legislation is an integrated system that governs the actions and results of this society, and that the goal of the Islamic religion and legislation is to achieve and save the five purposes: religion, self, money, supply and birth as well as justice, equality and human life reform. Architecture is one of the most effective means by which human beings achieve these goals, as well as being the most expressive of the culture of societies, which is powerful and effective in other societies, which entails religious influence in architectural design it is the general problem of research</p> <p>As well as the Islamic legislations derived from the Quranic texts and the noble Hadiths on the urban work which formed the special problem of the research and the study of a group of studies. The research problem was identified by: (<strong>the lack of knowledge of the impact of Islamic legislation on the crystallization of architectural products Contemporary at the level of thought and application</strong>), and the study aims to enrich knowledge about the role of Islamic legislation in the development of Arab Islamic architecture with the contents of the essence of the spirit of the age and the research adopted the descriptive analytical methodology, which includes the construction of a conceptual framework and the construction of a theoretical framework, which is the first step in solving the research problem .</p> <p>The most important of the research findings is (between communication and continuity, the human architecture to create creative products linked to the architecture of Islamic architecture and the ability of those products to keep up with contemporary through the realization of human needs and desires changing time and place) to conclude the research conclusions, recommendations and sources</p> Mahdi Saleh A.H.
