The aim of the research is to identify the problems of teaching computer material concerning fourth grade students’ point of view in the computer department in the College of Education for Women by identifying the statistically significant differences between the answers of female students to problems in the field of school administration and in the field of teaching computer subject included the sample of research On (39) of (50) students and (78%) From the fourth grade students in the department of computer who had achieved the theoretical part in the first semester and the assembly application in the second semester in the schools of Baghdad city for the academic year (2018-2019). In order to verify the two objectives of the research; a closed questionnaire was set . It consisted of (37) paragraphs addressing the problems of teaching the subject of Computer science. Then (17) paragraphs reflecting problems related to the field of administration. And (20) paragraphs reflecting problems in the field of teaching the subject on the triangular scale (yes, no, I don't know). The questionnaire is presented to a group of experts specialized in the field of teaching methods, measurement, evaluation and computer to determine its suitability for application, The stability of the resolution determined using half-hash method where it reached (0.60) which is a good stability factor, the resolution was applied to the fourth graders in the department of computer immediately after the end of the period of the assembly application to identify the most important problems encountered during that period in Baghdad City Schools. After the use of repetitions and percentages and square Kai it was recognized that the most important problems suffered by computer teachers in the Baghdad City Schools and according to the importance are: lack of internet and Assisting books in school, lack of weekly hours to teach the subject, lack of computer books, The belief that computer material is secondary material in the school, the lack of sufficient computers in the school laboratory In the field of teaching the subject, the most important problems are the lack of the net in the teaching of the subject, the lack of training students on the use of computer skills, lack of interest in field visits related to the computer ,the use of traditional teaching method A set of recommendations and proposals related to the current research field are concluded...
لابد لكل باحث في أي موضوع يرغب في عن القارة الافريقية والمناطق المسلمة منها بشكل خاص ان يتلمس طرق حريتها وتحريرها وانعتاقها علية التحري والبحث عن العقدة الدينية التي عتنقها اهلها والتي جعلت منهم تواقين الى الحرية واثر هذة العقدة على ذلك الانسان في التحرير من كل اشكال العبودية
يتضمن البحث طرق تحضير والخواص الكيمائية لمشتقات حلقة 1,3,-4 اوكسادايازول المعوضة في الموقعين 2,5 . كما يتضمن كيفية تحضير بوليمرات بلورية سائلة من المركبات الحلقية غير المتجانسة لحلقة 1,3,-4 اوكسادايازول المعوضة والطرق الطيفية المستخدمة في تشخيص المركبات المحضرة.
A simple all optical fiber sensor based on multimode interference (MMI) for chemical liquids sensing was designed and fabricated. A segment of coreless fiber (CF) was spliced between two single mode fibers to buildup single mode-coreless-single mode (SCS) structure. Broadband source and optical signal analyzer were connected to the ends of SCS structure. De-ionized water, acetone, and n-hexane were used to test the performance of the sensor. Two influence factors on the sensitivity namely the length and the diameter of the CF were investigated. The obtained maximum sensitivity was at n-hexane at 340.89 nm/RIU (at a wavelength resolution of the optical spectrum analyzer of 0.02 nm) when the diameter of the CF reduced from 125 μm to 60 μ

Tanuma and Zubair formations are known as the most problematic intervals in Zubair Oilfield, and they cause wellbore instability due to possible shale-fluid interaction. It causes a vast loss of time dealing with various downhole problems (e.g., stuck pipe) which leads to an increase in overall well cost for the consequences (e.g., fishing and sidetrack). This paper aims to test shale samples with various laboratory tests for shale evaluation and drilling muds development. Shale's physical properties are described by using a stereomicroscope and the structures are observed with Scanning Electron Microscope. The shale reactivity and behavior are analyzed by using the cation exchange capacity testing and the capillary suction test is

Each organization struggles to exploit each possible opportunity for gaining success and continuing with its work carrier. In this field, organization success can be concluded by fulfilling end user requirements combined with optimizing available resources usage within a specified time and acceptable quality level to gain maximum profit. The project ranking process is governed by the multi-criteria environment, which is more difficult for the governmental organization because other organizations' main target is maximizing profit constrained with available resources. The governmental organization should consider human, social, economic and many more factors. This paper focused on building a multi-criteria optimizing proje

The current research aims to prepare a proposed Programmebased sensory integration theory for remediating some developmental learning disabilities among children, researchers prepared a Programme based on sensory integration through reviewing studies related to the research topic that can be practicedby some active teaching strategies (cooperative learning, peer learning, Role-playing, and educational stories). The Finalformat consists of(39) training sessions.
Multiple linear regressions are concerned with studying and analyzing the relationship between the dependent variable and a set of explanatory variables. From this relationship the values of variables are predicted. In this paper the multiple linear regression model and three covariates were studied in the presence of the problem of auto-correlation of errors when the random error distributed the distribution of exponential. Three methods were compared (general least squares, M robust, and Laplace robust method). We have employed the simulation studies and calculated the statistical standard mean squares error with sample sizes (15, 30, 60, 100). Further we applied the best method on the real experiment data representing the varieties of
