Background: Chronic cigarette smoking is one of the major risk factors for coronary artery disease. However, it has additional cardiac adverse effects independent of coronary atherosclerosis. Patient and Methods: After informed consent and perm- ission from the review board of the hospital, 80 healthy subjects who were classified as smokers or non-smokers were included in the study. They were examined by standard echocardiography protocol which was followed by two-dimensional speckle tracking to assess the functions of the right ventricle. Results: The tricuspid annular plane systolic excursion (TAPSE) was significantly reduced in smokers as compared to non-smokers (P < 0.05). The tricuspid flow peak late diastolic velocity (A wave) was sig

The present theoretical study concerning the relation between anthropology and education has discovered the existence of differences in points of view between teachers related to socialization. Anthropologists see socialization as the process in the child acquires the culture of society tike shills, habits, types of behaviors, norms and social values. Sociologists concentrate on the problems of learning, and the types of social behaviors. Social sciences can be considered as integrated unity concerning the realization of objectives. However they hold various opinions about this subject.

The mobile device be used in all fields in society to be the life is more easy. So that it's used in the instructional operation and that need to study the effective of it in the teaching operation. The aims of research are known the effect of using the Bluetooth techniques in the mobile upon students' achievement and their retention of information. The sample consist of (34) students in the first class in Electrical Techniques Department in Technical Institute of Nassiriayah at (2010 – 2011) which divided to two equivalent groups, experimental and control by using the two equivalent groups design. Seven subjects were choices of Electrical Installation subject in second course. The researcher limited the teaching objectives and built t

The Aim of this study is to identify the importance of associations and professional associations in the field of libraries and information at the global level and at the Arab level through analytical study carried out by the researcher adopted the security of the international federation of libraries IFLA model at the global level, associations, Egyptian information and libraries in the Arab world and the imposition study a number of recommendations. Most important to increase funding for unions and professional associations, and the need to establish sessions and meet with the owners of the profession in order to exchange experiences and skills development.

The paper is devoted to solve nth order linear delay integro-differential equations of convolution type (DIDE's-CT) using collocation method with the aid of B-spline functions. A new algorithm with the aid of Matlab language is derived to treat numerically three types (retarded, neutral and mixed) of nth order linear DIDE's-CT using B-spline functions and Weddle rule for calculating the required integrals for these equations. Comparison between approximated and exact results has been given in test examples with suitable graphing for every example for solving three types of linear DIDE's-CT of different orders for conciliated the accuracy of the results of the proposed method.

The aim of the research is to design educational software based on Web Quests and to measure its effectiveness in developing information search skills of students at the Department of Educational and Psychological Sciences. The research is experimental in nature using pre-post measurement. The research sample consisted of (91) male and female students from the second grade in the Department of Educational and Psychological Sciences, they were divided into two equal groups; the experimental group consisted of (47) students who adopted the educational software as a studying method, and the control group consisted of (44) students who follow the traditional method. The researchers prepared a list of skills for searching information and they

The concern of this article is the calculation of an upper bound of second Hankel determinant for the subclasses of functions defined by Al-Oboudi differential operator in the unit disc. To study special cases of the results of this article, we give particular values to the parameters A, B and λ
