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...

Steady conjugate natural convection heat transfers in a two-dimensional enclosure filled with fluid saturated porous medium is studied numerically. The two vertical boundaries of the enclosure are kept isothermally at same temperature, the horizontal upper wall is adiabatic, and the horizontal lower wall is partially heated. The Darcy extended Brinkman Forcheimer model is used as the momentum equation and Ansys Fluent software is utilized to solve the governing equations. Rayleigh number (1.38 ≤ Ra ≤ 2.32), Darcy number (3.9 * 10-8), the ratio of conjugate wall thickness to its height (0.025 ≤ W ≤ 0.1), heater length to the bottom wall ratio (1/4 ≤ ≤ 3/4) and inclination angle (0°, 30° and 60°) are the main consid

The background subtraction is a leading technique adopted for detecting the moving objects in video surveillance systems. Various background subtraction models have been applied to tackle different challenges in many surveillance environments. In this paper, we propose a model of pixel-based color-histogram and Fuzzy C-means (FCM) to obtain the background model using cosine similarity (CS) to measure the closeness between the current pixel and the background model and eventually determine the background and foreground pixel according to a tuned threshold. The performance of this model is benchmarked on CDnet2014 dynamic scenes dataset using statistical metrics. The results show a better performance against the state-of the art

A widespread variety of toxicants modify miRNAs profiles in target tissues. Five rat treatment groups were selected for this study, each consisting of five animals and an additional one left untreated used as a control. Administration of the carcinogen 4-Nitroquinoline (4-NQO) lasted for 5 months with four weeks intervals separating the successive groups. When the carcinogen intake period ended, the animals were euthanized and renal tissue was collected for both histopathological and molecular investigations. The results showed no significant difference (p=0.65) between the animal groups that showed kidney tissue toxicity and those that did not. Conversely, a statistically significant difference emerged if the m

The numerical investigation has been performed to study the radiation affected steady state laminar mixed convection induced by a hot inner varied positions circular core in a horizontal rectangular channel for a fully developed flow. To examine the effects of thermal radiation on thermo fluid dynamics behavior in the eccentric geometry channel, the generalized body fitted co-ordinate system is introduced while the finite difference method is used for solving the radiative transport equation. The governing equations which used are continuity, momentum and energy equations. These equations are normalized and solved using the Vorticity-Stream function. After validating numerical results for the case without radiation, the detailed rad

Coherent noise such as ground roll and guided wave is present in the seismic line DE21 (East Diwaniya south eastern Iraq) and it obscures seismic signal and degrades from the quality of data. To attenuate the coherent noise from the shot gather and the Stack of the seismic line, AGORA filter was applied in order to obtain the good signal as the hyperbola shape in shot gather and the reflectors will be clearly to interpret it later. It has given good results and the coherent noise was attenuated in high ratio on all the line. The spectrum analysis is confirmed the effectiveness of AGORA filter to attenuate the coherent noise.

Background: In advanced diabetes mellitus, serum levels of the most hormones are altered due to several interplaying mechanisms. Objective: To assess the relation of serum leptin and lipid profile in type 2 diabetic nephropathy. Patients and Method: Serum leptin levels and its relation to lipid profile were estimated in 62 patients with type 2 diabetic nephropathy attending the National Diabetes Center in Al- Mustansiriya University, and (26) healthy individuals considered as control group. The diabetic patients were classified into three groups, (24) pathients with normoalbuminuria (21) patients with microalbuminuria and (17) patients with macroalbuminuria. Fasting plasma glucose, serum creatinine, Hb A1c %, lipid profile (Total c
