The presentwork is a theoretical study in the field of charged particle optics. It concentrates on the design of electrostatic enzil lens for focusing charge particles beams, using inverse method in designingthe electrostatic lens. The paraxial ray equation was solved to obtain the trajectory of the particles, the optical properties such as the focal length and spherical and chromatic aberration coefficients were determined. The shape of the electrode of the electrostatic lens were determined by solving poison equation and the results showed low values of spherical and chromatic aberrations, which are considered as good criteria for good design.
Gypseous soil covers approximately 30% of Iraqi lands and is widely used in geotechnical and construction engineering as it is. The demand for residential complexes has increased, so one of the significant challenges in studying gypsum soil due to its unique behavior is understanding its interaction with foundations, such as strip and square footing. This is because there is a lack of experiments that provide total displacement diagrams or failure envelopes, which are well-considered for non-problematic soil. The aim is to address a comprehensive understanding of the micromechanical properties of dry, saturated, and treated gypseous sandy soils and to analyze the interaction of strip base with this type of soil using particle image

Show MoreBackground: Asthma is a common chronic disease in children in which the body’s airways swell, preventing the lungs from filling with air, there are many different inflammatory cells involved in asthma which can synthesize and release cytokines which are recognized to be important in chronic inflammation and play a critical role in the inflammatory response. Objectives: to assess the local effect of ICS on oral tissue by measuring Interlukine-12 level and Candida albicans colony in saliva among12 year's old asthmatic children who were collected from AL- Zahra Center Advisory for Allergy and Asthma, and compares them with non-asthmatic children of the same age and gender.Type of the study: Cross –sectional study.Methods: The total samp
... Show Moret-Self-Compacting Concrete (SCC) reduces environmental noise and has more workability. This research presents an investigation of the behavior of SCC under mechanical loading (impact loading). Two types of cement have been used to produce SCC mixtures, Ordinary Portland Cement (OPC) and Portland Limestone Cement (PLC), which reduces the emission of carbon dioxide during the manufacturing process. The mixes were reinforced with Carbon Fiber Reinforced Polymer (CFRP) which is usually used to improve the seismic performance of masonry walls, to replace lost steel reinforcements, or to increase column strength and ductility. Workability tests were carried out for fresh SCC. Prepared concrete slabs of 500×500×50mm were tested for lo

These training programs did not get enough attention from athletes especially young athletes; their training was restricted to physical abilities like strength, speed, and endurance instead. The research aimed at designing an apparatus for developing athletes’ balance in national centers for gifted/ ministry of youth and sport so as to provide a measurement for coached in this field. The results showed that the designed apparatus have a positive effect on developing the subjects’ balance in boxing and basketball athletes.

Predictability of School Environment in the tendency to aggressive behavior among high primary school students. This study aimed at exploring the Family and school environment predictability of the tendency to aggressive behavior among high primary school students in Irbid Second Directorate of Education. The study sample consisted of 784 male and female students in the high-primary schools of Irbid Second Directorate of Education, chosen as on random cluster sampling method. Three aspects of school environment had the predictability of the tendency to aggressive behavior. The academic orientation of students explained 9.9% of the total variation in the dependant variable while the relationships between peers explained 1.6% and the teach

The effect of partial substitution for veal with TSP quality, sensory characteristics such as color and homogenizing of the stuffing, taste, flavor, juiciness and overall acceptability was evaluated by taste panel. The obtained results showed that product prepared with replaced 15 and 20% were acceptable by panel taste without significant differences compared to control. The values of taste panel score dropped as the rate partial replacement increased a level of TSP 25 and 30% as compared to control. It can be concluded the possibility of using manufacture

To achieve the study aims , the researcher has chosen intentionally this sample to apply the experiement . The study sample cosists 0f (58) female students distributed randomly on two groups. The experiemental group is taught according to problem- solving strategy and it is (29) female students, while the control group which is also (29) individuals is taught according to the traditional way of teaching . The two groups have been matched statistically in term of age , the academic achievement for the father and mother , intelligence, and the linguistic ability. The exp

The previous studies have dealt with the role of the linguistic vocabulary and Arabic calligraphy in interior spaces in terms of decoration and design. However, this research sheds light on the importance of linguistic vocabulary in the construction of design thought and how it has become the a basic motivation in the process of scientific and practical construction and not just aesthetic formations that took their place in the interior spaces, as linguistic vocabulary emerged recently and echoed within the specialization of interior design and formed a key motive to explor
