And to see the effect of learning cells strategy in personnel variables for this study (critical thinking and reflective thinking) Researcher adopted the measure ready for critical thinking and is a measure of (al-Kaabi, 2005) critical thinking component of (99) test paragraph and which covered (5) the capacity of thinking Critic is a reproduction and knowledge of assumptions or postulates, deduction, interpretation, calendar pilgrims, as a promising researcher himself a measure of reflective thinking fits with the nature of the course material, students and be the scale of (30) items distributed among the five skills of reflective thinking and are (meditation and observation , disclosure of events, access to conclusions, to give convincing explanations, put the proposed solutions and check out the virtual charity and applied to exploratory sample of (50) Tbalba and ensure the effectiveness of the false alternatives and ratified the selection and steadfastness and at the end of the experiment researcher tests applied to Standart critical thinking and reflective thinking on the experimental group and the control and the use of appropriate statistical methods researcher students to address the findings of the current research, which yielded the following results: - 1. The existence of differences statistically significant at the level (0.05) between the experimental group taught according to students learning strategy cells and the control group, which is considering the geographical material itself in the traditional way of thinking and critic for the experimental group and thus rejects the hypothesis Asfrah first. 2. there is a statistically significant difference at the level (0.05) between the experimental group which is studying the geographical material in accordance with the learning strategy cells and the control group students taught the same material in the traditional way of thinking and contemplative for the experimental group and thus rejects the hypothesis Asfrah first. And the researcher to a number of conclusions in the light of the results of the search, including: - 1. develop the skills of critical thinking skills and reflective thinking to the fifth grade in literary geographical material students through the use of strategy (learning cells). 2. Students feeling in the bilateral groups in the strategy of learning cells that they perform their duties classroom bilaterally and collectively cooperative and their sense of being responsible for their duties in bilateral their groups towards achieving the goals lead to learning an active and effective over the way Altqldeh, which led to the development of critical thinking skills and reflective thinking for students Group Altgeraah skills. 3. The use of Zdhu practice (learning cells) as an activity of intellectual activity leads to increased student information in geographical material and giving them Mtaadh skills such as the ability to reflect and think and disposal and the analysis and planning of the activities of their cooperation and teamwork and respect for the views of others . And researcher recommended in light of the results, including the following: - 1. cells use learning strategy in teaching geographical material for the preparatory phase for the purpose of further development of skills Altvkiran critic and contemplative. 2. Working on the teaching of teachers in-service by the Ministry of Education on how to use the cells to learn strategy and economy baptized on teaching methods that rely conservation and indoctrination. And researcher suggested in light of the results as follows: - 1. conduct a similar study on the other stages of the study and both sexes to see the effect of using the cells learning strategy in the development of critical thinking skills and reflective thinking skills of students in the geographical material. 2. further studies to determine the impact of the use of learning strategy cells in variables other than critical thinking and contemplative Mthelalatjahat about geographical material and retention of information and motivation to learn.

Characterization of Metal Dispersion of Some Naphtha Reforming Catalysts by Methylcyclohexane Dehydrogenation Reaction
...Show More Authors

The dispersion of supported Pt and Pt–Ir reforming catalysts have been studied, after treatment with oxidative and reducing atmosphere. Methylcyclohexane dehydrogenation reaction in the absence of hydrogen was used as a test reaction. An attempt was made to relate the behavior of the catalysts upon subject to reaction, to the dispersion of the same type of catalysts upon treatment with similar atmosphere and temperatures which appeared in literature. The total conversion of reaction can be explained by a change in metal dispersion. Thus, methylcyclohexane dehydrogenation reaction appears to be a really “structure sensitive” reaction.

      The toluene yield increases as the oxidation temperature i

Hong-Ou-Mandel Dip Measurements of Two Independent Weak Coherent Pulses for Free Space Quantum Key Distribution Systems
...Show More Authors

Preparation of identical independent photons is the core of many quantum applications such as entanglement swapping and entangling process. In this work, Hong-Ou-Mandel experiment was performed to evaluate the degree of indistinguishability between independent photons generated from two independent weak coherent sources working at 640 nm. The visibility was 46%, close to the theoretical limit of 50%. The implemented setup can be adopted in quantum key distribution experiments carried out with free space as the channel link, as all the devices and components used are operative in the visible range of the electromagnetic spectrum.
