The astronomic view of The Village of Graw
Get PDFThe star view of the village of Graw is located on the mountain of Darre Lolkan, opposite the village of Graw. You're a. It is located at the foot of The Black Head Mountain, 25 kilometres northeast of Erbil. It's a hose. The light of the dakhha has not been able to reach all the revelations, the benefits and benefits of the people, and who and who is hesitant about this way? Is it made? The view comes from a set of corners, each of which is in a prominent location. Ascendant was created , after much observation of the sunset and the hard work and nightlife of many observations escaping or setting up many stars by the founder of this view based on change The earth's position is built according to the sun as a result of the rotation around the sun. According to The Grawi Perspective and Calendar , the year is divided into four seasons . Sun in the evening of the day 20/12 on The early winter corner will be like this, according to the day 21/12 ( the first day of the winter season . As The evening of the day (20/3) on the third corner of the corners of the scales will be like this, so the day 20/3 (last) It's winter. According to this, 21/3 will be the first day of the Kurdish spring and New Year season. As The evening of the day (20/6) will be like this on the corner of the beginning of summer, so the day 20/6 (the last day of the season) It's going to be spring. After that and as a result of the earth's rotating to finish another half a minute the same time it repeats the appearance of the horns at sunset. And this time it's the same as before Must be reversed by one after the coming of the armpits. Day 22/9 (sun on the third corner It will be like this in the corners of the scales, so the day will be 22/9 (the last day of the summer season and the day of 23/9) the first It's autumn day. As the day 20/12 (the sun will be like this on the corner of the beginning of winter, so the day 20/12 will be the last day of the autumn season.

A New 2×2-Element Subarray Antenna Synthesis Based on Waveguide Cavity Resonators
Get PDFA new design of a 2×2-element subarray antenna based on an all-cavity resonator structure is presented in this article. A novel topology which employs only two resonators to lay out the subarray is proposed, and two X-band rectangular waveguide cavity resonators are utilized for the subarray physical implementation. The first resonator is a conventional half-guided resonator operating at the TE101 mode. The second resonator, which is an oversized TE102 resonator based, is modified in order to keep the TE101 mode to propagate within the bandwidth of interest and facilitate the connection with four radiating apertures. The developed coupling matrix approach is utilized to calculate the desirable frequency response, which is a standard 2nd order Chebyshev response with introducing filtering functionality to the realised gain response of the subarray. The simulation results obtained by two simulation softwares (CST and Ansoft HFSS) validate the calculation results. An extremely wide impedance bandwidth of 23% at center frequency 10 GHz when the reflection coefficient S11 = -10 dB is obtained. A very stable realised gain with less than 0.5 dBi variations over the bandwidth of interest (8.8-11.1 GHz) is obtained with a peak gain value of 13.1 dBi at 11 GHz. The radiation patterns have very low side lobe levels, particularly in the E-plane, due to the existence of small non-radiating area and maintaining small spacing between the radiating apertures. The proposed 2×2-element subarray has the advantages of wider bandwidth and low profile compared with our and other previous 2×2-element subarrays
Evaluation of sexual dimorphism by radiographic analysis of mental orifice and mandibular height in a sample of Kurdish population of Iraq
Get PDFBackground: A vital part of forensic anthropology is to differentiate between sexes by morphologic analysis of osseous tissue. One of these osseous structures that displays a significant degree of sexual dimorphism is mandibular bone. Gender variances in the mandibular anatomy, from its height, position of mental orifice, gonial angle, bigonial width and bicondylar breadth have been observed in various studies.This study was aimed at evaluating the sexual dimorphism based on the average length between the upper and the lower edge of the mental orifice to the mandibular lower border and the mandibular height on right and left side of the jaw on digital panoramic radiographs in a sample of Kurdish population of Iraq. Methods: Panoramic radiographs of 460 patients (230 males and 230 females) were included in the study. The length from both inferior and superior margins of mental orifice to the mandibular lower border and the mandibular height in the mental orifice region was measured on both left and right sides. The data was statistically analysed to estimate the differences among the sexes using Independent sample t-test. Results:The mandibular height in the mental orifice region from alveolar crest to mandibular lower border was more in males as compared to the females, this being statistically significant. The length from superior margin and inferior margin of mental orifice to the mandibular lower border and the mandibular height was more in males as compared to females but was not statistically significant. Conclusion: The height of the mandible in the mental orifice region showed significant sexual dimorphism in the sample of Erbil population
The impact of economic uncertainty, economic growth and energy consumption on environmental degradation in MENA countries: Fresh insights from multiple thresholds NARDL approach
Get PDFThis paper explores the influence of economic policy uncertainty on environmental quality in selected MENA countries depending on an augmented STIRPAT model over the period 1970–2020. ARDL model and its extensions like augmented ARDL, augmented NARDL, and MTNARDL models are applied to detect any possible effect from uncertainty index to carbon dioxide (CO2) emissions. The empirical results reveal the validity of environmental Kuznet curve (EKC) curve in all the countries. Moreover, the results show that the uncertainty index enhances environmental degradation, especially in extremely large changes in Morocco, Turkey, and Iran. Besides, the findings reveal that energy consumption and population in the entire sample escalates CO2 emissions over the study period. Consequently, policymakers in MENA countries should consider the economic uncertainty index, particularly in light of its recent rise, when developing any strategies and plans aimed at improving environmental standards, as well as the need to encourage the use of renewable energies in order to increase the percentage of their contribution to total energy consumption

Pre-School Education and Different Approaches That Emerged in Historical Development
Get PDFThe history of pre-education is quite recent. In fact, in order for this education to start, it was necessary to wait for the formal education to spread to the whole society. Pre-school education, which emerged and designed to meet the needs of post-industrial societies, gave importance to the cognitive, affective and psychomotor development of students. Especially the educational needs of post-war societies also required pre-school education. In this context, three different approaches to pre-school education have emerged. The common point of these approaches is that they adopt a democratic education model and reject the authoritarian teacher role in the traditional education model. Thus, a reflection of humanity’s democratization adventure in the modern age has also shown itself in education models
