SYNTHESIS AND CHARACTERIZATION OF NEW DEMULSIFIER FROM NATURAL AND SYNTHETIC POLYMER: SYNTHESIS AND CHARACTERIZATION OF NEW DEMULSIFIER FROM NATURAL AND SYNTHETIC POLYMER
...Show More Authors

ABSTRACT

This research included the preparation and characterization of new demulsifies from natural and synthetic polymers of chitosan and polyvinyl alcohol that are environmentally friendly and at the same time have high efficacy comparable to emulsifiers. imported foreign. The prepared compounds were examined using infrared spectroscopy and nuclear magnetic resonance spectroscopy, and all the spectral signals of the polymers were in good agreement with the chemical composition of the polymers. And the melting and decomposition that occur on polymers at high temperatures. The effect of the length and type of side chain in the compositions of polymers on the process of water separation of oil emulsions was studied, and they had an important impact on the levels of water separation. The solubility behavior of polymers was also known, so that there was a solubility difference in Different organic solvents according to the type of the side chain of a hydrocarbon nature, and the best solubility of the prepared polymers was a solvent (dimethyl sulfoxide). The best polymerization time was found (12) h, as well as the best temperature at which polymerization takes place is (70 °C) and the prepared emulsion was compared with The commercial emulsifier was evaluated for its efficiency in separating water from crude oil (crude oil Basra) and compared to the commercial emulsifier, it was more efficient than the commercial one in separating water from oil.

In the South of yement, when the accupation of Aden in 1839 by the British, British politics has proceeded in accordance with interests in promoting the existence and exploitation of this important site to implement their interests. Historians believe that Britain played a major role in the conflicts that have taken place on the land of Yemen, through a series of military and political dealings between them and the Ottoman Empire prior to withdrawal of Yemen and between local authorities and power to Yemen, such interactions have led to very serious consequences for the future of Yemen and Yemen was often divided into three parts, the northern areas under the authority of Imam Yahya, and the South, under the control of Britain, Asir and

Populism in the Middle East: Discourse and Comparative Characteristics
...Show More Authors

Abstract: The premise of the study is that populism is a process of building political views and critical intellectual orientations among the general public. It is transformed into mass beliefs by mobilizing the society ideologically and continuously in order to reach or control the circle of authority. We distributed the study topics to four sections: In the second, we will discuss the contents of contemporary populism and how other forms of populism evolved historically. The third is to discuss the political discourse of populism among the military regimes and the comparative Islamic parties in the Middle East, especially in terms of the essence and the intellectual foundations. The fourth section seeks to examine the characteristics o

Financial corruption and investment opportunities in the Iraqi economy
...Show More Authors

Corruption is one of the barriers to economic growth and investment opportunities, and after the most serious security and stability, that corruption plagued the Iraqi economy is striking and has roots since the eighties of the last century to the present day.

The study aimed to identify practical impact of corruption on investment in the Iraqi economy and revealed the possibilities and obstacles to investment in Iraq and clarify the investment opportunities at the level of Iraq and the impact of corruption on investments.

The focus will be on the statement of the extent of corruption and investment in Iraq and the adoption of the style of economic measurement using cross-section

Space suitability and its functional implications in interior design
...Show More Authors

The current research dealt with the study of space compatibility and its role in enhancing the functional aspect of the design of the interior spaces of isolation hospitals by finding a system or format that is compatible with the nature of the changes occurring in the structure and function of the space system, as well as contributing to enhancing compatibility between the functional aspect and the interior space. Therefore, the designer must The interior is the study of the functional and spatial aspects as they are the basic aspects for achieving suitability, and through the interaction between the person and the place, the utilitarian performance characteristics are generated that the interior designer is interested in and tries to d

Association between Gallstones and Diabetics Type 2 Iraqi Patients
...Show More Authors

Gallstone disease is one of the most common complications among diabetic patients especially type 2 DM. Till now, there is no specific and certain factor that explain the incidence of gallstones among type 2 diabetic patients and many risk factors are taken collectively to estimate its intensity and severity compared to non diabetic counter parts. This clinical study was designed to evaluate and report the incidence and severity of gallstones among type 2 diabetics and non diabetics regarding certain factors. 20 diabetic females and 20 diabetic males were collected as patients′ group and have had gallstones while 20 females and 20 males who have had gallstones without diabetes mellitus type 2 were collected as controls′ group

Structural and optical properties for PVA- PEG-MnCl2 composites
...Show More Authors

Polymer films of PEG and PVA and their blend with different
concentrations of MnCl2 (0, 2, 4, 6 and 10 %.wt) were study using
casting technique. The X-ray spectra of pure PEG, PVA and
PVA:PEG films and with addition of 2% concentrations from
(MnCl2) show amorphous structures. The results for FTIR show the
interaction between the filler and polymer blend results in
decreasing crystallinity with rich amorphous phase. This
amorphous nature confirms the complexation between the filler and
the polymer blend. The optical properties of (PVA:PEG/MnCl2)
contain the recording of absorbance (A) and explain that the
absorption coefficient (α), refractive index (n), extinction coefficient
(ko) and the dielectric cons

Association Between Periodontal Disease and Atherosclerotic Cardiovascular Diseases: Revisited
...Show More Authors

Atherosclerotic cardiovascular disease (ACVD) is an inflammatory disease of the coronary arteries associated with atheroma formation, which can cause disability and often death. Periodontitis is ranked as the sixth most prevalent disease affecting humans affecting 740 million people worldwide. In the last few decades, researchers have focused on the effect of periodontal disease (PD) on cardiovascular disease. The aim of this review was to investigate the association between these two diseases. PD is a potential risk factor that may initiate the development, maturation, and instability of atheroma in the arteries. Two mechanisms were proposed to explain such association, either periodontal pathogens directly invade bloodstream or in
