The diversity of cultures is still the title of an Iraqi specificity that gave the society a diversity and this is reflected in the journalistic reality with the changing of the political system generate a new political and ideological life that differs from what is prevailed during the decades. However, its exacerbation of the degree of division is an additional duty for the press as a cultural platform and a knowledge bridge that contributes to the process of dialogue, addressing the differences, establishing a politically homogeneous structure through the state and socially by uniting all components of society and working to raise public awareness of the importance of national belonging to build a modern state. Cultural diversity is a human moral and intellectual necessity that leads to peaceful coexistence and building a human being who respects values and freedom of expression and opinion in order to create modern institutions and a civilized society based on tolerance and exchange of ideas. Therefore, the gradual transformation of political reality led to the challenge of press which indicates media in how to contribute to the process of repairing cracks and confront the ideological differences and prevailing cultures. One of the most prominent of this difficult stage is the occurrence of deadly doublets and dynasties in Iraqi cultural structures. The contemplative historian senses that two basic lines of Iraqi intellectuals have been starting together since the formation of the state and they contribute to live in conflict between them in 2003 after the defeat of the state and the laxity of society. This is reflected in an Iraqi political-national cultural line that represents the radical-socialist trend which began utopian, class-oriented and Marxist at the parties. While the second line represent the national trend and later ideologically envied by the parties and national groups. The decline of the two trends has led to a different cultural and ideological direction that represent political Islam and its control over the political and societal reality, taking advantage of the failure of those forces in the two previous directions. To conflict in the structure of culture with the invention of regional and international shares in situation of plowing the mental and unconscious infrastructure of the individual reflected on the cultural environment of the community to live a kind of turmoil, which led to different trends in the structure of press in accordance with the variables to produce a speech. It is a sign of the new reality. The press has been a manifestation of change that has been associated with the political system and its relationship to the nature of the facts of the new environment. Therefore, there is a link between the evidence of the press and the possibility of forming an ideology that is consistent with the cultural structure by means of various information, news, analysis, article, and the possibility of controlling external press institutions and the work controls that govern the structure of the institutions internally. These restrictions and restrains have defined the path by which each press organization operates through its structure of human staff. And the capital which is the core and the starting point for the establishment and the continuation of the existence of the means and then the goals embodied in the speech that is characterized by this newspaper or that in the production of ideas and opinions, information and texts and they deal to communicate to the public to influence the trends and their tendencies and not to employ diversity and marketing through the various media in its ideological tendencies leading to division and then to a social and political conflict.
Statement of the Problem. The use of orthodontic fixed appliances may adversely affect oral health leading to demineralizing lesions and the development of gingival problems. Aims of the Study. The study aimed to coat orthodontic archwires with chlorhexidine hexametaphosphate nanoparticles (CHX-HMP NPs) and to evaluate the elusion of CHX from CHX-HMP NPs. Materials and Methods. A solution of CHX-HMP nanoparticles with an overall concentration of 5 mM for both CHX and HMP was prepared, characterized (using atomic force microscope and Fourier transformation infrared spectroscopy), and used to coat orthodontic stainless steel (SSW) and NiTi archwires (NiTiW). The coated segments were characterized (using scanning electron microscopy
... Show MoreThe massive growth of the automotive industry and the development of vehicles use lead to produce a huge amount of waste tire rubber. Rubber tires are non-biodegradable, resulting in environmental problems such as fire risks. In this search, the flexural behavior of steel fiber reinforced self-compacting concrete (SFRSCC) beams containing different percentages and sizes of waste tire rubbers were studied and compared them with the flexural behavior of SCC and SFRSCC. Micro steel fiber (straight type) with aspect ratio 65 was used in mixes. The replacement of coarse and fine aggregate was 20% and 10% with chip and crumb rubber. Also, the replacement of limestone dust and silica fume was 50%, 25%, and 12% with ground rubbe

Show MoreWater saturation is the most significant characteristic for reservoir characterization in order to assess oil reserves; this paper reviewed the concepts and applications of both classic and new approaches to determine water saturation. so, this work guides the reader to realize and distinguish between various strategies to obtain an appropriate water saturation value from electrical logging in both resistivity and dielectric has been studied, and the most well-known models in clean and shaly formation have been demonstrated. The Nuclear Magnetic Resonance in conventional and nonconventional reservoirs has been reviewed and understood as the major feature of this approach to estimate Water Saturation based on T2 distribution.

Samples of gasoline engine oil (SAE 5W20) that had been exposed to various oxidation times were inspected with a UV-Visible (UV-Vis) spectrophotometer to select the best wavelengths and wavelength ranges for distinguishing oxidation times. Engine oil samples were subjected to different thermal oxidation periods of 0, 24, 48, 72, 96, 120, and 144 hours, resulting in a range of total base number (TBN) levels. Each wavelength (190.5 – 849.5 nm) and selected wavelength ranges were evaluated to determine the wavelength or wavelength ranges that could best distinguish among all oxidation times. The best wavelengths and wavelength ranges were analyzed with linear regression to determine the best wavelength or range to predict oxidation t
... Show MoreRecently, the application of geosynthetics in the reinforcement of weak subgrade is expanded dramatically. However, selection of the geo-material that fits site conditions and soil type is crucial to achieving the success of the overall performance of such improvement. Also, the road life and cost construction are significant keys for evaluating this type of ground treatment. This paper presents an overview of the subgrade strengthening with geosynthetics to acquire a better understanding of the technique and to provide a clear guide for transportation and geotechnical engineers. The rutting failure along with its main causes are highlighted briefly. The types of geosynthetics, their applications and
