Occurred in recent years a huge revolution in the educational computer applications, and is still the use of computers in the field of education in its infancy and that increasing day after day, and started to take many forms, it is computer education to the use of the Internet in education and finally emerged the concept of e-learning, which depends on technical to provide educational content to the learner a good and effective manner and e-learning programs have become is gaining importance in the present time of its ability to overcome the knowledge explosion problem, due to the magnitude of the intellectual production in various scientific and humanitarian fields and the inability of traditional education for the overall merits of diverse disciplines and that briefing programs because of the difficulty update and delivery of information by traditional methods, objective of this research is to highlight the concept of e-learning and the reasons that compel us to pay attention to this aspect addition to identifying the obstacles that prevent progress or application of this branch of education in Iraq, and what is proposed for the development work in the field of e-learning solutions, The study relied on access to the reality of e-learning in Iraq through its role in Iraqi universities, and research found to emphasize the existence of a significant shortfall in this area addition to the lack of infrastructure provide for the advancement of e-learning Although an Iraqi universities today are trying to take advantage of e-learning programs , in the development of the educational process after falling during the past two decades to a large degree, and despite the existence of important steps have been achieved in this direction, particularly at the level of the provision of equipment and laboratories, and secure internet connection, but the traditional methods of education are prevalent in the general universities, Furthermore, many of the devices and laboratories, which have been processed for the purposes of e-learning, consumed before it is invested in real, or used for other purposes, which at best provide Internet services, or computer labs to teach, and in other conditions used for printing the official books and questions exam, or lecture halls, this study concluded submit a number of proposals and recommendations, which focused on attention to outreach to the community and the teacher and the learner, and to provide or infrastructure development, and provide full support to institutions and individuals, as well as to focus on creating educational content in accordance with the international quality standards.

nacks was made from yellow corn and its blends had contained corn, barley, chickpea, cumin, black cumin, black pepper and lettuce seeds at different levels considerable as lettuce seeds of ingredient and products were defined as physical, chemical and sensory evaluation. The results showed that the chickpea had contained the highest in protein and total lipids 40.60 and 15.50%. The black pepper, chickpea and cumin seeds had contained higher in crude fiber (14.20, 10.71 and 10.50%, respectively). The snacks with lettuce seeds showed that the protein was the highest in group (2) it was 15.04, 16.44 and 17.82 %. Total lipids, crude fiber and ash content were decreased gradually in the snacks from group (1) 4.02, 4.87 and 5.72% and the highest in total lipids in group (2) which contained 4.23, 5.08 and 5.93%, respectively. Hunter color values of snacks control and its different blends from lettuce seeds the group (6) prepared with 60% corn grits and 15, 10 and 5% barley and also 6% lettuce seeds showed that higher in lightness and yellowness till 15% chickpea and nearly control snacks. The highest (WAI) and (WSI) were in groups (1 and 2) respectively made from 40% corn grits and 40, 35, 30 and 25% barley. The sensory properties showed that the extrusion blend (18) made from 20% chickpea and 5% barley the highest acceptability (95%) and nearly control (96%) followed were by 10 and 15% chickpea plus 15 and 10% barley were gave 93.0 and 88.0% during overall acceptability.

In this paper a numerical study for the natural convection in an enclosure withadjacent single wall using vertical adiabatic partition attached to bottom wall. The verticalwalls of the enclosure are isothermal while the bottom and top horizontal walls areinsulated. The temperature of the left vertical wall is higher than the temperature of theright vertical wall. The study included a change in the inclination of the cold wall of(f=15°, 30° and 45°), Rayleigh number of (Ra=103 to 105), length of partition of (YP= 0.2,0.3 and 0.4) and location of partition of (XP=0.25 and 0.5). A finite difference method wasapplied to solve the governing equations using Gauss-siedel iterative technique. Results forthe mean Nusselt number, and contour maps of the streamlines and isotherms line arepresented. It has been found that Nusselt number increases with an increase in Rayleighnumber, inclination of cold wall with percentage of (10-16%) and location of partition withpercentage of (3-14%) while decreases with increasing in partition length with percentageof (5.4-7%).

This paper proposes different types of an active filters design. A comparative study between the theoretical analysis and practical design of different types of analog filters is presented.In this paper a comparison is made between Mat lab simulation toolbox for the Butterworth, Chebyshev, Elliptical filter and a practical simulation using Electronic workbench (EWB).In general, the results prove that a good agreement between the practical (experimental) and computer simulation (theoretical) by using the available Matlab toolboxes.
