...Show More Authors

The current research aims to know the effect of gardens ideas strategy on deductive thinking among fourth-grade science students in physics.
   To investigate from the aim of the research, researchers put the following zero
hypothesis:

- No statistically significant differences at the level of significance (0.05) between the students mean scores of the two groups on indicative thinking test.

      The research was carried out on the scientific fourth grade male students in Al – Mansour in Baghdad; belong to Education Directorate Al- Karkh /1, for the Academic Year (2014-2015) A.D.

      Prepared research requirements included ] selected the scientific subject chapters ( 5,6,7,8,9  and 10 ) from physics  text book, the formulation of behavioral objectives, prepared  instructional  plans for the experimental groups and control groups[ , after the presentation to a group of specialists .

      The researchers applied the research tool by themself, indicative thinking test of (32), according to their psychometric properties.

      The research sample was selected intentionally by the researchers which consisted of (80) male students, Randomized into two groups (40) students in experimental group and (40) students in control group.

      The two groups students have been equalization by the following variables: (Pre physics knowledge, physics scores at mid-year, age in month, intelligence, indicative thinking).

      Experimental group students studied by using indicative thinking strategy and the control group students studied by using traditional method, researcher studied the two research groups by himself three lessons per week.

      Research tool was applied, indicative thinking test.

      Statistical tools used to deal with the results.

      The results showed (There is a statistically significant difference) between the experimental & control group students on indicative thinking test, favor the experimental group students.

      According to mentioned  above , the  researchers  had  a number  of  recommendations  which  including  to use gardens ideas strategy  in teaching physics.

      In light of the results, Researchers suggested making similar studies in several subjects, and the stages of a study to identify the impact in the achievement, and the attitude towards physics subject and other variables

Improving IoT Applications Using a Proposed Routing Protocol
...Show More Authors

The main objective of this work is to propose a new routing protocol for wireless sensor network employed to serve IoT systems. The routing protocol has to adapt with different requirements in order to enhance the performance of IoT applications. The link quality, node depth and energy are used as metrics to make routing decisions. Comparison with other protocols is essential to show the improvements achieved by this work, thus protocols designed to serve the same purpose such as AODV, REL and LABILE are chosen to compare the proposed routing protocol with. To add integrative and holistic, some of important features are added and tested such as actuating and mobility. These features are greatly required by some of IoT applications and im

Proposed Modification to Increase Main Swept Back Wing Efficiency for Aircraft Aermacchi Siai S211
...Show More Authors

A winglet is devices attached at the wing tips, used to improve aircraft wing efficiency by reduction influence wing tips vortices and induct drag, increasing lift force at the wing tips and effective aspect ratio without adding greatly to the structural stress and weight in the wing structure. This paper is presented three-dimensional numerical analysis to proposed modification swept back wing by adding Raked winglets devices at the main wing tips belong the two seat trainer aircraft type Aermacchi Siai S211 by using Fluent ANSYS 13 software. CFD numerical analysis process was performed at the same flight boundary conditions indifferent wing angle of attacks with constant air flow velocity V∞ =50 (m/sec), ambient pressure Po=101325 (P

Blastocystosis is symptomatic infection caused by the protozoal parasite Blastocystis , which resides in the intestinal tract of its hosts and it is one of the most common parasites reported in humans. It’s prevalence ranges between (30 - 50%) of the population in developing countries. This genus has a worldwide distribution and often the most commonly reported human intestinal protozoan in children and adults, even infect infants

Roller compacted concrete: Literature review
...Show More Authors

Roller compacted concrete (RCC) is a material with no slumps and is made from the same raw materials as conventional concrete. The roller compacted dam method, the high paste technique, the corps of engineers method, and the maximum density method are all ways of designing RCC. The evolution of RCC has resulted in a substantial change in construction projects, most notably in dams, because of the sluggish pace of conventional placement, consolidation, and compacting. The construction process was accelerated by incorporating RCC into dams, resulting in a shorter construction period. Research shows that the dams that used RCC had completed one to two years sooner than the dams that used regular concrete (Bagheri an

Eight different Dichloro(bis{2-[1-(4-R-phenyl)-1H-1,2,3-triazol-4-yl-κN3]pyridine-κN})iron(II) compounds, 2–9, have been synthesised and characterised, where group R=CH3 (L2), OCH3 (L3), COOH (L4), F (L5), Cl (L6), CN (L7), H (L8) and CF3 (L9). The single crystal X-ray structure was determined for the L3 which was complemented with Density Functional Theory calculations for all complexes. The structure exhibits a distorted octahedral geometry, with the two triazole ligands coordinated to the iron centre positioned in the equatorial plane and the two chloro atoms in the axial positions. The values of the FeII/III redox couple, observed at ca. −0.3 V versus Fc/ Fc+ for complexes 2–9, varied over a very small potential range of 0.05 V.
