The current study aims to develop a proposed educational program based on augmented reality (AR) technology, in addition to assessing its effectiveness in developing research and historical imagination skills of the Humanities Track's female students at the secondary stage, as well as assessing the correlative and predictive relationships between the amount of growth for the two dependent variables. To achieve this, a secondary school in the city of Makkah Al-Mukarramah was chosen, and an available random sample of (30) female students from the study population was selected. The quasi-experimental approach was followed by this study, particularly one group design. In addition, two tools were used to collect study data, namely: a test of situations for historical searching skills, and a classroom observation card about historical imagination skills. Descriptive and inferential statistics were used to analyze the data of the study by using SPSS. The results of the study revealed that there were statistically significant differences at the level of significance (α ≤0.01) between the mean scores of the study group in the pre and post-applications in the test of situations for historical searching skills, and classroom observation card about historical imagination skills on the side of the post application. In addition, the results showed that there was a significant (high) impact of the proposed educational program on the study sample, as the coefficient of impact for the two dependent variables reached (4.94, and 5.07) respectively, and the Black coefficient of the two independent variables reached (1.32،1.30) respectively, which can be indicative of the high effectiveness of the two dependent variables of the educational program. At the significance of (a≤0.01) between the two dependent variables, a strong positive correlation was proved by the findings, as the correlation coefficient mounted to (0.850). Furthermore, a liner predictive correlation was revealed by the findings, as the value of (b) reached (19.204, 038.) respectively at the significance of (α ≤0.01) between the two dependent variables for searching and historical imagination skills, which raised each of them to the other one's level. Study results led to a number of conclusions, as well as recommendations and proposals that were appropriate

Two-dimensional crystal has been achieved and controlled
with the aid of DC electric field applied between two electrodes at 5
millimeters separating distance between them. Sol-gel method has
been used to prepared nanosilica particle which used in this work as
well as TiO2 nanopaowder. The assembly of the silica particles is
due to the interaction between the electrical force, the particles
dipole, and the interaction between the particles themselves. When a
DC voltage is applied, the particles accumulated and crystallized on
the surface between the electrodes. The Light diffraction
demonstrates that the hexagonal crystal is always oriented with one
axis along the direction of the field. The particles disass

This research presents an experimental investigation of the rehabilitation efficiency of the damaged hybrid reinforced concrete beams with openings in the shear region. The study investigates the difference in retrofitting ability of hybrid beams compared to traditional beams and the effect of two openings compared with one opening equalized to two holes in the area. Five RC beams classified into two groups, A and B, were primarily tested to full-failure under two-point loads. The first group (A) contained beams with normal weight concrete. The second group (hybrid) included beams with lightweight concrete for web and bottom flange, whereas the top flange was made from normal concrete. Two types of openings were considered in this s

The Electrocardiogram records the heart's electrical signals. It is a practice; a painless diagnostic procedure used to rapidly diagnose and monitor heart problems. The ECG is an easy, noninvasive method for diagnosing various common heart conditions. Due to its unique advantages that other humans do not share, in addition to the fact that the heart's electrical activity may be easily detected from the body's surface, security is another area of concern. On this basis, it has become apparent that there are essential steps of pre-processing to deal with data of an electrical nature, signals, and prepare them for use in Biometric systems. Since it depends on the structure and function of the heart, it can be utilized as a biometric attribute
