Designation and Study of Anticlines- Kurdistan Region-NE Iraq
Authors: Ahmed Sirwan H
Published: October 2019

Iraq is located in the Western Asian continent particularly in the northern Arabian promontory. Iraq approximately lies in center of Middle East. The area of investigation cover northern and northeastern parts of Iraq-Kurdistan Region. Iraq and Kurdistan region are located in the northern Arabian Platform. The study area includes the northwestern extension of the Zagros Mountain range (the Zagros Fold and Thrust belt). Through study of Tectonic analysis, Stratigraphy, Geomorphology and satellite images; we try to constrain new classification with designation of the anticlines and compression stress orientation in Zagros fold belt. The northeastern and northern Iraq contain huge anticlines and synclines. They have been formed as a result of compression stress. These forces formed by collision of Arabia and Eurasian plates during Eocene-Miocene periods. Most of the anticlines characterize by double-plunging symmetrical to semi-symmetrical fold. The shield of the anticlines in the High Folded Zone mostly compose of carbonate sequence from Cretaceous formations. The core has Jurassic-Triassic formations. In the other hand the shield of anticlines in Low Folded Zones are Cenozoic formations. The plunging and terminate anticlines was caused by Cretaceous pre-tilting extensional normal faults. These fault become barriers in front of growing the anticlines longitudinally as example in Kosrat and Shakrok anticlines. The Cretaceous lateral facies change affected on the bend of anticline axis. The northwestern of Azmar anticline and southeastern of Surdash anticline seem to be En-echelon plunging; through this study we find out they are belong to one anticline. The Surdash-Azmar fold Axis shape is Bezier line while passing through facies change between Qamchuqa and Balambo Formations. The same phenomenon can be find in Aqra-Bekhme anticlines by facies change of Aqra-Tanjero formations. In this study, we try to make two or more anticlines to be show as one large anticline. In previous studies they split anticline into two or more anticlines because of having geomorphological features such as valley and lakes. However we try to show that valleys and lake are not barriers and not affect termination of the anticline as shown in Shirin, Bradost, anticlines are one individual anticline.

L−1 for each, in addition to their combination, on some growth characters of the two ornamental plants. Plants were sprayed three times. Treatments were layout in factorial experiment (3x3) in completely randomized design with three replicates. Results showed that the use of the two materials at both concentrations caused significant increase in Chinese carnation plant height. Leaf number increased significantly at 2ml.L−1 of micronutrients mixture on Chinese carnation. In gazania, there was a pronounced increase in leaf number with the increase of the concentration of seaweed extract. Sea weed extract had no effect on percent dry weight while the percent increased significantly at both concentrations on Chinese carnation. Chlorophyll content increased due to the use of the highest concentration of both materials on both plants. Number of flowers per plan also increased as a result of the spray of both materials. Length of flower stalk and flower diameter was affected significantly by all the treatments, while flower fresh and dry weight did not affect by the treatments. Nitrogen percent in leaves of Chinese carnation increased significantly due to the use of the two materials, but in gazania the percent increased due to the use of the two concentrations of seaweed extract while the micronutrients had no effect. For carbohydrate content, there was pronounced increase in leaves of both plants especially at the higher concentration of both materials.

The soil was plowed and disturbed at two levels. The top layer were plowed by the two bodies of moldboard plow which they were one of the combined machine parts, the deep soil layers were disturbed by two subsoilers which were the second part of the combined machine. The manure was mixed with plowed and the disturbed soils by the three shallow tines of the combined machine (third part). Manure was broadcasted by the manure feeding mechanism which the machine was provided with. Randomize Complete Block design (RCBD) was used with three replicates to carry out the experiments. The experiments parameters were two moldboard plow depths (20cm (M20) and 30cm (M30)), three subsoiler depths (20 (S20), 30 (S30) and 40cm (S40)). These three subsoiler depths were used with moldboard plow depth of 20cm only, whereas, the other three subsoiler depths (10 (S10), 20 (S20) and 30 (S30)) were used with moldboard depth of 30cm. The combination of the moldboard plow depths and the subsoiler depths gave three machine depths (40, 50 and 50cm) i.e M20S20, M20S30, M20S40, M30S10, M30S20and M30S30. These treatments were conducted without and with manure application of 45.5 ton ha−1. The experiments were conducted in silty laom soil.

Initial Sticking Coefficient Attenuation of Gases in Carbon Monoxide Sensing on Pt80Au14Ti6
Authors: Marjunus R
Published: October 2019

It has been proved that Pt80Au14Ti6 can give proper signals as a CO sensitive layer in air at room temperature. Unfortunately, there is no signal anymore from this sample, if it is kept in air more than 24 hours. To overcome this problem, we carried out dry etching technic. The atmosphere testing also has been done in technic etcher chamber by keeping the samples separately in Ar, N2, CO, and O2 with pressure 1 atm for 24 hours without taking out the samples after etching process from the chamber. These experiments found that oxygen causes this loss signal problem. Oxygen can diffuse up to 170 Angstrom under the Pt surface to be subsurface oxygen. This diffusion changes the surface structure of Pt(100)(1x1) to hex-Pt(100) which impacts the attenuating of the initial sticking coefficient of gases. Simulations which have been conducted in this research produced the attenuating factor, i.e., 1 − 0.00585 exp (5.76664O
sub), where O
sub is the concentration of subsurface oxygen.

Cognitive attributes such as Junior high school science general weighted average, elementary general weighted average, and National Career Assessment Examination result and psychosocial aspects like classroom learning environment and teacher quality were significantly correlated with science performance of which the Junior high school science average (β = 0.194), elementary average (β = 0.096) and classroom learning environment (β = 0.132) were the predictors of science performance. The study puts forth the notion that the most fitting structural model of students’ performance in science is when it is anchored on the cognitive ability of the students and supported by their physical aspect of science leaning environment. Students with high cognitive ability supported by conducive, well-equipped physical facilities in science, expectedly perform better. It is recommended that the stakeholders may anchor their learning modules and activities on the different levels of learners’ cognitive abilities and needs. Likewise, they may provide public secondary schools with adequate learning resources to have an optimal learning in science to cope with the demands of 21st Century towards quality science education for all.

Published: October 2019

The environmental degradation that occurred in the past and continues nowadays is a failure of our society and education system in providing the understanding and skills needed by students. Schools and teachers have the responsibility to develop students’ literacy skills, especially ecological literacy. Therefore, to achieve that purpose, the availability of teaching materials with ecological literacy is needed. This research aims at explaining the ecological literacy values in four Indonesian language textbooks for senior high school students based on 2013 curriculum. To examine the ecological literacy values both descriptive and distributive, content analysis is used as the main method. The study used a mixed approach to analyze both qualitative and quantitative data in a single study. Based on the analysis result, the ecological literacy values include (1) ecological knowledge (general knowledge, socio-political systems, and environmental issues), (2) affective tendency (factors within the individual), (3) behaviour (assumption of personal responsibility and self-control), and (4) cognitive skills (related to environmental issues). However, the content of ecological literacy value is more dominant on materials dealing with ecological knowledge and has not emphasized on all other components. Furthermore, the analysis of the passage about knowledge component contains the most comprehensive information of all.

Published: October 2019

This study aims to determine the effect of self-regulation on the ability of motion coordination of elementary school students. Motion experience and physical activity in elementary school children proved to have a positive effect on children’s physical, psychological, and social development. In addition, physical education in elementary schools is oriented to laying down the foundations of basic movement and movement, so that in the future, children will grow-up and develop into complete personalities that are in harmony and in harmony with age. Coordination ability is one of the basic components of motion. Self-regulation is internal motivation, which results in the emergence of a person’s desire to determine goals in his life, planning strategies to be used, and evaluating and modifying the behaviour that will be carried out. The method used is a quasi-experimental method that examines the effect of self-regulation on coordination ability of elementary school students. The instrument used for data retrieval on the variable of self-regulation is a questionnaire, while the variable of ability to coordinate the motion used the test. The results of this study show that self-regulation contributes to the ability to coordinate motion. Self-regulation of elementary school students has a varied contribution to the components of motion coordination, namely: the ability to assemble movements, distinguish, the ability to maintain balance, the ability to maintain balance, adapt movements, find and maintain the rhythm of movement, react and change direction.
