Synthesis, Structural and Biological Efficiency Studies of New Azo Ligands and Their complxes with Zn(II), Cd(II) and Hg(II) Metal ion

The formation of Zn(II), Cd(II) and Hg(II) complexes was studied with two new hetrocyclic azo ligands 2-[4-(1-sulfonaphthalene)azo]-L-Histidine (L1) and 2-[7-(1-hydroxy3-sulfonaphthalene)azo]-L-Histidine (L2) derived from coupling reaction of diazonium salt of naphthionic acid and 7-amino-1-naphthol-5-sulfonic acid with L-Histidine in an alkaline ethanolic solution. The structural features of all new compounds have been characterized from their elemental analyses, metal content, magnetic moment measurement, molar conductance & FT-IR, UV-Vis. and 1HNMR spectral studies. Furthermore,the composition of complexes have been studied following the mole ratio method after fixing the optimum condition (pH and concentration).Beer’s law was obeyed over a concentration range (610-5 - 810-5M). All data showed that the complexes with (1:2) (M:L) metal to ligand, may be formulated as [M(L)2Cl2] and octahedral geometry, in which the ligands (L1 and L2) act as N,N-bidentate chelating agents, coordinated through the azo nitrogen near naphthyl moiety and heterocyclic nitrogen in L-Histidine. The stability constant () and Gibbs free energy (G) of the complexes have also been studied. Biological efficiency of ligands and their complexes were tested aginst Eschericha coli and Staphylococcus aureus.

The Interactive Communication and its Reflection on Social Capital

The Internet makes the world like a small village. It has the ability to make groups of the same ideas, thoughts, and identity close to each other by gathering them in one place. It is a way to communicate and share information and opinion; shaping and sharing of comprising individuals with common interests and the participation of individuals in a fruitful dialogue results in achieving a set of goals promote ideas and mobilizing people about issues and events of common interests.

To address the relationship of the internet via interactive communication and its ability to achieve social capital and discuss issues and various social events, the study sees that the problem of the study could be formulated as follows:

Sleep Disorders Following Mild and Moderate Traumatic Brain Injury

(1) Background: Sleeping disorders are frequently reported following traumatic brain injury (TBI). Different forms of sleeping disorders have been reported, such as sleepiness, insomnia, changes in sleeping latency, and others. (2) Methods: A case-control study with 62 patients who were victims of mild or moderate TBI with previous admissions to Iraqi tertiary neurosurgical centers were enrolled as the first group, and 158 patients with no history of trauma were considered as the control. All were 18 years of age or older, and the severity of the trauma and sleep disorders was assessed. The Pittsburgh sleep quality index was used to assess sleep disorders with average need for sleep per day and average sleep latency were assessed in

Spatial transformations and visual construction in the contemporary theater

The current research deals with the subject of spatial transformations and visual construction in contemporary theater. How the visual system works to create spatial diversity in the contemporary Iraqi theater performance and how visual construction contributes to a spatial development process capable of building a tourism system that creates an architectural architecture that leaves the topography of the scriptural architecture. And the production of various indications and patterns in the scene of theatrical presentation in order to produce the new foundational meaning by creating a new structure that leads to diversity and diversity in the visual system and the beginning of visual constructions and their applications.

Symbolic significance and its effectiveness in industrial product design

The current research dealt with the symbolic significance and its effectiveness in the design of the industrial product, the aesthetic communicative discourse that embodies the imagination and human conscience. Whether according to what has been termed custom or what has been approved by traditions long ago, symbolism may be the main actor in linking the identifying components of the product. In addition, symbolism provides the user with the key to accessing a direct awareness of the product’s shape and function, as an identification of the product by stimulating the symbolic form of the consumer’s imagination and inviting him to To meditate in order to realize the implicit meaning behind these forms and thus achieve the symbolism of

Populism in the Middle East: Discourse and Comparative Characteristics

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

Political Culture and Civil Society in Algeria: Problematic relationship

In light of what constitutes the cultural factor from a great importance in the context of the incorporation of an active and participant civil society in the process of democracy- building and the achievement of political development, this article tries to look at the concept of the political culture and the civil society with the stand on the nature of existing relationship between them in its theoretical part, then the move to dissection of the civil society crisis in Algeria under the prevalent cultural values for understanding the relationship between the two variables in its empirical part, as a step towards the detection on the pivoting of democratic values in activating the political participation and attainment the democratic co

Genetic characteristics and β-cell Autoimmunity in T1DM Children

Background: TIDM is known to be polygenic disease that appears from the interaction of mutation in multiple genes including HLA. The autoimmune mediated destruction of
pancreatic β-cells is reflected by the presence of autoantibodies against prominent antigens in the pancreatic β-cells.
Objective: This study was designed to investigate the role of HLA-class I and class II antigens in the etiology of type 1 diabetes mellitus (T1DM) and also assessment of
glutamic acid decarboxylase (GAD65) autoantibodies in the patients at the onset of the disease.
Patients & Methods: Sixty T1DM patients who were newly onset of the disease (diagnosed less than five months) were selected. Eighty apparently healthy

Fuzzy Survival and Hazard Functions Estimation for Rayleigh distribution

In this article, performing and deriving the probability density function for Rayleigh distribution by using maximum likelihood estimator method and moment estimator method, then crating the crisp survival function and crisp hazard function to find the interval estimation for scale parameter by using a linear trapezoidal membership function. A new proposed procedure used to find the fuzzy numbers for the parameter by utilizing (     to find a fuzzy numbers for scale parameter of Rayleigh distribution. applying two algorithms by using ranking functions to make the fuzzy numbers as crisp numbers. Then computed the survival functions and hazard functions by utilizing the real data application.

Good Governance between Parliamentary Reform and Partisan Think Tanks

The idea of rationalizing parliamentary work tends to reduce the functions of parliament in favor of the government’s authority as a result of its inefficiency in discussing contemporary issues، especially in regimes that suffer from the absence of a political majority and the tendency of parties to achieve their interests. thus making the parliament’s jurisdiction limited to deciding on basic issues such as those related to human rights according to Objective criterion، and the development the legislations of framework  . Providing the knowledge needs for MPs helps in achieving a rational debate، and Lawmaking effective through the presence of Research institutions which support the representatives in parliamentary work.
