  • Changes in Interaction Between Accessory Protein 8 and IL-17RA in UK
           Isolates Caused by Mutations in the SARS-CoV-2 Open Reading Frame 8

    • Authors: Ekrem AKBULUT
      Abstract: SARS-CoV-2 is the infectous agent of Covid-19, one of the most important health problems of the twenty-first century. IL-17RA is an crucial receptor in the generation of the host immune response. ORF8 is the viral accessory protein of SARS-CoV-2 that suppresses the host immune response. Mutations can alter the viral properties and clinical course of SARS-CoV-2. In this study, we investigated the changes that SARS-CoV-2 ORF8 mutations may cause in the interaction of IL-17RA with ORF8. The study was carried out using 825 complete genome sequences from UK isolates. Mutation analyzes were performed using RDP4 and MEGAX. The protein model was created using the Swiss Model. Protein protein interaction was analyzed by Haddock ver 2.4. Analysis of changes in protein stability was performed using SDM2, mCSM stability and DUET tools. The change in ORF8 - IL-17RA binding affinity before and after the mutation was evaluated using mCSM-PPI2. We detected P30S, R52I, Y73C and L118V mutations in SARS-CoV-2 ORF8. Mutations have been shown to reduce protein stability and affinity. After the mutation, the binding dynamics of ORF8 to IL-17RA were changed. Molecular attachment scores were -78.0±3.4 kcal.mol-1 and -76.3±11.9 kcal.mol-1, for wild type and mutant, respectively. After the mutations, the hydrogen bond number and position between ORF8 and IL-17RA changed. While establishing ten hydrogen bonds between the wild type and IL-17RA, four hydrogen bonds were established between the mutant ORF8 and IL-17RA. The decreased affinity between ORF8 and IL-17RA can be seen as a stronger immune response and a milder clinical course. Although our results contain important data for understanding ORF8, which is an important drug target, it needs to be repeated with in-vivo and crystallgraphy studies.

  • On the Mechanical Behavior of Distinct Auto Wheel Materials Under Static
           and Dynamic In-service Loading Cycle

    • Authors: Aniekan IKPE; Emem IKPE, Ekom ETUK
      Abstract: Automobile wheels serve as a primary means of support to a moving and stationary car while being subjected to static and dynamic loading in the process. The present study examines the mechanical behavior of different auto wheel materials under the aforementioned loading conditions using Finite Element Method (FEM). The wheel was modlled and simulated in SOLIDWORKS 2018 version using different materials including carbon fibre (T300), cast alloy steel, aluminium (2014-T6) and magnesium alloy. Considering the simulation conditions of lowest static stress (von-mises), lowest resultant strain, lowest displacement (static and raidal) and lowest bending, cast alloy steel met all the requirements except for static strain where carbon fibre was the lowest followed by cast alloy steel. Carbon fibre (T300) among all the materials had the highest static stress (von-mises), highest displacement (static and raidal) and highest bending. Static stress for aluminium (2014-T6) was lower than that of magnesium alloy while resultant strain, static and radial displacement as well as bending was lower for aluminium (2014-T6) than magnesium alloy. Von-mises stress for all the wheel materials where below their yield strength, indicating that they can perform optimally under the above mentioned loading condition. The primary concern with steel wheel is the high density which serves as additional advantage to the other three materials due to their low density, but steel wheel is inexpensive, strong, tough and more durable compared to the other materials.

  • An Investigation on Radiation Shielding Properties of Borosilicate Glass
           Systems

    • Authors: Duygu ŞEN BAYKAL; Huseyin Ozan TEKİN, R. Burcu ÇAKIRLI MUTLU
      Abstract: The aim of this research is to examine the radiation shielding properties of 5B2O3-40SiO2-(55-x)Al2O3-xBaO (BSABa-x) glass systems, which are containing barium and aluminum oxide added to borosilicate glasses, with varying from 25 to 34 weight fractions. Shielding parameters, such as linear attenuation coefficients (LAC), mass attenuation coefficients (MAC), mean free path (MFP), effective atomic number (Zeff), effective electron density (Neff), half-value layer (HVL), tenth-value layer (TVL), effective atomic weight (Aeff), exposure buildup factors (EBF) and energy absorption buildup factors (EABF) enable us to obtain information about the radiation shielding power of composite glass material groups. Therefore, the mass attenuation coefficients (MAC), for the 0.015–15 MeV gamma-ray energies are obtained by using the Py-MLBUF online software to determine photon shielding parameters of BSABa-x glasses. The results are shown that the glass which contains higher BaO concentration has higher mass attenuation coefficients. BSABa-34 glass has the highest MACs, ranging from 0.111 cm2/g to 90.400 cm2/g, while BSABa-25 glass has the lowest values, ranging from 0.099 cm2/g to 69.000 cm2/g. The BSABa-34 glass with the highest BaO contribution has the thinnest MFP and HVL values. In addition, photon buildup is minimized by adding BaO to the BSABa-x glasses. Accordingly, we can conclude that adding BaO to aluminum borosilicate glasses at increasing rates, improves nuclear radiation resistance properties.

  • Comprehensive Analysis of Forest Fire Detection using Deep Learning Models
           and Conventional Machine Learning Algorithms

    • Authors: Süha Berk KUKUK; Zeynep Hilal KİLİMCİ
      Abstract: Forest fire detection is a very challenging problem in the field of object detection. Fire detection-based image analysis have advantages such as usage on wide open areas, the possibility for operator to visually confirm presence, intensity and the size of the hazards, lower cost for installation and further exploitation. To overcome the problem of fire detection in outdoors, deep learning and conventional machine learning based computer vision techniques are employed to determine the fire detection when indoor fire detection systems are not capable. In this work, we propose a comprehensive analysis of forest fire detection using conventional machine learning algorithms, object detection techniques, deep and hybrid deep learning models. Experiment results demonstrate that convolutional neural networks outperform other methods with 99.32% of accuracy result.

  • Investigation of Natural Occurring Radioactive Material Activity Level in
           Falluja-Anbar (Iraq)

    • Authors: Sabah FARHAN; Faez WAHEED, Mohammed AL-DULAIMI
      Abstract: Radiation may be defined as the energy in the form of electromagnetic waves or particles that pass through space and even heavy dense materials. The radioactivity is a continuously decreasing quantity which is a function of the half-life of the responsible radionuclides. The natural sources of radiation came from terrestrial radionuclides which are widely distributed in the earth's crust.Field radiological surveys were conducted by the GR-460 mobile detection system, the only mobile system in Iraq and the region. This system is dedicated to the radiological scanning process for large areas and in less time. The system is attached to a GPS satellite positioning device so that the measurement points are coupled with the spatial coordinates of the radiometric area.In this study, the concentration of naturally occurring radioactive materials had been determined experimentally of AL-Falluja / Anbar Governorate- Iraq for (66) km2 using GR-460 portable gamma spectrometer system. The results showed that the high level of uranium concentration (238U) was 8.1 ppm in the industrial area, the low level was 0.1 ppm in most districts. The high level of Thorium (232Th) concentration was 17.5 ppm and less than 0.1 ppm in most neighborhoods are within Iraq's natural background.

  • Comparison of Mechanical Properties of Gypsum with and without
           Polypropylene Fibers

    • Authors: Xheneta XENGO; Bashkim ZİBERİ, Naim SYLA
      Abstract: Gypsum is a mineral belonging to the group of sulfates, i.e., sulfuric acid, which is often found in Earth's crust. In this paper, two main types of gypsum, gypsum α and gypsum β, with different water content were prepared. Samples with and without polypropylene fibers, with different fiber content and different fiber lengths during preparation, produced in a gypsum factory located in the Debar region, North Macedonia, were studied. Physical properties such as density, porosity, water absorption capability and their kinetics, packing factor, hardening and others were examined using different methods. The main goal of this paper was the determination of mechanical properties of gypsum such as the compressive and flexure strength and the module of elasticity of the gypsum prisms. For the determination of elastic properties, the nondestructive method of ultrasound testing was used. In this test, the strength and quality of a prism is assessed by measuring the velocity of an ultrasonic pulse passing through a gypsum structure. This test is conducted by passing a pulse of ultrasonic wave through a prism and by measuring the time taken by the pulse to get through the structure. Higher velocities indicate good quality and continuity of the material, while slower velocities may indicate gypsum with many cracks or voids. The comparison of the obtained results from these two types of gypsum shows different mechanical and other physical properties.

  • Optimization of Stamping Process Parameters

    • Authors: Tunahan ÇİFTÇİ; Levent AYDIN, İrem ERTEN
      Abstract: Stamping is one of the significant sheet metal forming processes which is used forproducing components especially in the automobile industry. Sheet metal flow into the die cavity occurs the applied force in the stamping process. While the extreme compressive stresses of sheet metal end up with wall thickening, tensile stresses lead to thinning problems in the wall zone of the part. The excessive thinning may cause crack formation or fracture of the metal sheet. This faulty process design eventually produces non-conforming products. In order to have a successful design of the stamping process, designing tooling and identification of the optimum level of the process parameters are needed. In this regard, the present paper is an attempt to set the stamping process parameters for minimum thinning of blank and optimal results by a stochastic search method (modified Differential Evolution) based on multiple nonlinear regression analysis. The results have been compared with the results of those of the previous study. It is shown that the current results show that the present optimization study is successful as it further increases the thickness.

  • Comparison of Experimental Curves of Alloy Steels after Gas Nitriding

    • Authors: Naim SYLA; Fisnik ALİAJ, Njomza ELEZAJ, Bashkim DALİPİ
      Abstract: This study is concerned with experimental curves of: hardness, residual stress and concentration of nitrogen at the precipitation layer at alloy steels after gas nitriding. The purpose of this treatment is that through experimental curves to identify the relationship and causality between hardness, on one side, and on the other, residual stress respectively concentration of nitrogen. Comparing the shape and slope of these curves we can conclude that, concentration of diffused nitrogen on the steel lattice, respectively ferrite, is a cause of increased hardness at the precipitation layer. More to the point, as a result of nitrogen diffusion, residual stress emerge which cause increase of hardness. The intensity and slope of the curves of hardness depends on the intensity and slope of the nitrogen concentration respectively residual stress.
