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 outstanding evidence of phthalimide pharmacophore in securing enhanced biological activities had encouraged further research and development into phthalimide-based derivatives as potential new drugs. In this study, phthalimide core was hybridized with aldehydes giving integrated imines displaying different types of functionalities and at alternating positions. The resulting compounds, therefore, provide an innovative window to explore possible differential biological effects as antioxidants and anticancer agents. A total of sixteen compounds were synthesized, and each was verified by FT-IR, H NMR, C NMR, and MS characterization. Herein, a facile single-step synthesis method was employed substituting the conventional two-step che

In the present article, we use a plasmonic bowtie nanoantenna working in the near infrared region to enhance the temperature confinement in the tissue. The Computer Simulation Technology Studio Suite package version 2019 was used to execute the design of both plasmonic nanoantenna and the tissue. Gold nanostructure and silicon carbide dioxide are the components the plasmonic nanoantenna in the bowtie shape. The results showed that the distance between the tumor tissue and the antenna is important to determine the intensity field where the maximum field is 5.9*107 V/m at a distance of 100 nm. The maximum
... Show MoreCurrently, one of the topical areas of application of machine learning methods is the prediction of material characteristics. The aim of this work is to develop machine learning models for determining the rheological properties of polymers from experimental stress relaxation curves. The paper presents an overview of the main directions of metaheuristic approaches (local search, evolutionary algorithms) to solving combinatorial optimization problems. Metaheuristic algorithms for solving some important combinatorial optimization problems are described, with special emphasis on the construction of decision trees. A comparative analysis of algorithms for solving the regression problem in CatBoost Regressor has been carried out. The object of
... Show MoreIn this work, a novel single-slope solar distillator of floating perforated absorber inserted with wicks (cotton ribbons), and a stepped distillator are designed and manufactured with the aim of developing the conventional distillator. They are examined experimentally at Baghdad, Iraq (33.3°N Latitude, 44.4°E Longitude) in order to enhance the freshwater productivity and the efficiency of the conventional distillator. Results showed that the daily productivity and efficiency of the stepped distillator are higher than that for conventional solar distillator by 30% and 36.19% respectively. The daily productivity and thermal efficiency for the distillator with the floating absorber are higher than that for the conventional distillator by 16%
... Show MoreHeat transfer process and fluid flow in a solar chimney used for natural ventilation are investigated numerically in the present work. Solar chimney was tested by selecting different positions of absorber namely: at the back side, front side, and at the middle of the air gap. CFD analysis based on finite volume method is used to predict the thermal performance, and air flow in two dimensional solar chimney under unsteady state condition, to identify the effect of different parameters such as solar radiation. Results show that a solar chimney with absorber at the middle of the air gap gives better ventilation performance. A comparison between the numerical and previous experimental results shows fair agreement.
