The issue of nuclear proliferation is one of the most vital issues as it reflects a form of dealing in the field of international relations. Therefore, the Middle East region has taken great interest in reducing the levels of nuclear armament and acquiring nuclear power within the strategic framework of the international and regional powers. The establishment of a nuclear-weapon-free zone in the Middle East region is currently one of the most important international and regional arrangements for controlling the levels of nuclear proliferation and attempting to build a state of stability and balance. In the Middle East and the world. The importance of the research comes from the fact that it deals with an important and vital issue: the issue of nuclear proliferation and its implications for the equation of the strategic balance in the Middle East after the events of September 11, 2001, which gained great importance in the post-cold war era. And to achieve some kind of stability and balance within the framework of the international and regional environment, especially in the Middle East, which has increased the importance of efforts in this regard the proliferation of nuclear weapons to new countries, it is possible to obtain nuclear technology by enhancing levels The proliferation of weapons of mass destruction has become one of the most important facts for the post-Cold War era. At a time when only five countries possessed nuclear weapons (the United States, Russia, China, France and Britain) , As well as the possibility of other countries such as India, Pakistan and Israel, which suggests that the post-Cold War era has seen a widening of the circle of States possessing or manufacturing such weapons (Pakistan, North Korea and Iran) The emergence of regional tensions as in the case of William Middle East. Thus, the issue of non-proliferation of weapons of mass destruction has become a central issue in the context of the post-Cold War American strategy, especially after the events of September 11, 2001, as a result of the convictions that there is an interrelationship between the non-proliferation of weapons of mass destruction and the global fight against terrorism. In keeping with this, the research started from the premise that the continuity of the Middle East countries in seeking to acquire nuclear capabilities is in itself an essential brake or determinant of the establishment of a zone free of weapons of mass destruction, as well as the lack of guarantees to establish security among countries The Middle East, which is reflected negatively on the regional and international security approaches to the Middle East, and of course lead to the adoption of their respective security policies against each other within the framework of the growing levels of nuclear weapons to achieve some kind of balance towards the nuclear capabilities of each of these countries And then more nuclear armament policies in the region, as a result can not promote positive security perceptions that are based on the employment of enablers of smart power, which is reflected negatively on the strategic balance in the territory of the Middle East equation.

Roller Compacted Concrete is a type of concrete that is environmentally friendly and more economical than traditional concrete. Roller Compacted Concrete is typically used for heavy-duty and specialist constructions, such as hydraulic structures and pavements, because of its coarse surface. The main difference between RCC and conventional concrete mixtures is that RCC has a more significant proportion of fine aggregates that allow compaction and tight packing. In recent years, it has been estimated that several million tons of waste demolished material (WDM) produced each year are directed to landfills worldwide without being recycled for disposal. This review aimed to study the literature about creating a Roller-Comp

Clarias gariepinus (Burchell, 1822) (Siluriformes, Clariidae) has been recognized as an alien species in Iraqi water bodies. This study aims to use molecular DNA to identify this catfish and trace its origins using. The DNA sequences of C. gariepinus were done using the mitochondrial DNA cytochrome c oxidase subunit 1 (COI) gene, and a specific primer set. The polymerase chain reaction (PCR) amplification was used to align the COI gene as a barcoding marker. After analysis, the sequences were compared with sequences in the National Center for Biology Information (NCBI) database

Iraqi conventional gasoline characterized by its low octane number not exceed 82 and high lead and sulfur content. In this paper tri-component or ternary, blends of gasoline, ethanol, and methanol presented as an alternative fuel for Iraqi conventional gasoline. The study conducted by using GEM blend that equals E85 blend in octane rating. The used GEM selected from Turner, 2010 collection. G37 E20 M43 (37% gasoline + 20% ethanol+ 43% methanol) was chosen as GEM in present study. This blend used in multi-cylinder Mercedes engine, and the engine performance, and emitted emissions compared with that produced by a gasoline engine.
The results show that this blend can formulate with available Iraqi pro

Show MoreThis work is based on the synthesis of Cobalt(II) and Cadmium(II) mixed-ligands compounds obtained from the reaction of N'-(4-methylsulfanyl-benzoyl)-hydrazine carbodithioic acid methyl ester as a ligand and using ethylendiamine (en), 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) as a co-ligand. The synthesis of ligand (HL) was based on multi-steps synthetic procedure. The reaction of 4-methylsulfanyl-benzoyl chloride with hydrazine gave 4-methylsulfanyl-benzoic acid hydrazide. This compound was reacted with carbon disulfide and potassium hydroxide in methanol to yield N'-(4-methylsulfanylbenzoyl)-hydrazine potassium thiocarbamate, which upon reaction with methyl iodide resulted in the formation of the ligand.

Show MoreAbstract* Backgrounds The retention of the maxillary complete denture may be influenced by adequate recording in the patient’s mouth, marking, and carving of the post-dam on the maxillary cast. Failure to do so may lead to loss of retention. Successful denture construction with patient’s comfort could be achieved by effective methods of recording, marking, and carving of the post-dam. The aim of the study was to assess Iraqi dentists in their knowledge and application of the post-dam in maxillary complete dentures. Methods Questionnaires were distributed randomly through online Google Forms and 118 Iraqi dentists with different academic degree participated in the study. A multinomial logistic regression model was also used to ass

A cross-sectional survey on 269 dentists was conducted using DASS-21 and PHQ-9 questionnaires. Bivariate and multivariate models were constructed and the odds ratio (OR) was calculated to assess the strength of the association between an independent categorical variable and the outcome.
