Boru hatlarının bütünlüğü farklı amaçlarla kullanılan çeşitli kaplama elemanlarının uygulanması ile sağlanabilmektedir. Her ne kadar farklı amaçlarla boru kaplamaları yapılsa da boru kaplamalarının en önemli uygulama amaçlarından biri yalıtımdır. Son yıllarda, çift katmanlı, üç katmanlı ve hatta bazı uygulamalarda üçten fazla katmanlı olarak uygulanan geleneksel ısı izolasyon kaplamalarının yerini tek katmanlı uygulamaların alması gelişen teknoloji ile gündeme gelmiştir. Bu deneysel çalışmada, içerisinden yüksek sıcaklıkta akışkan geçen boru hatlarının kaplanmasında tek kat olarak uygulanabilecek üç farklı kaplama malzemesinin deneysel sonuçları paylaşılmaktadır. Bu kaplama malzemeleri; akrilik dispersiyon esaslı kaplama malzemesi, çimento+stiren akrilik kopolimer bağlayıcılı genleşmiş cam, seramik, perlit ve inorganik dolgu malzemeleri ihtiva eden kaplama malzemesi ve çimento bağlayıcılı genleşmiş kil, doğal volkanik tüf, perlit ve inorganik dolgu malzemeleri ihtiva eden kaplama malzemesidir. Sabit özellikteki bir çelik boruya, her bir kaplama malzemesinden eşdeğer uygulama kalınlığı 24 mm olacak şekilde boru yüzeyine kaplama uygulaması yapılarak üç farklı harcın termal özellikleri tespit edilmiştir. Çalışma sonuçlarına göre, eşdeğer kaplama kalınlığında uygulandığında akrilik dispersiyon esaslı kaplama malzemesinin yüzey sıcaklık değerinin daha düşük derecelerde elde edilmesi sebebiyle ısı performansının daha yüksek olduğu tespit edilmiştir.
INVESTIGATION OF THE EFFECT OF BODY WEIGHT AND VEHICLE SPEED ON THE MEASUREMENT OF VIBRATIONS USED IN HIGHWAY PAVEMENT EVALUATION
Authors: KIRBAŞ Ufuk , KARASAHİN Mustafa
Published: March 2024

The study delved into investigating the impact of body weight on the determination of vibration parameters, as outlined in the ISO 2631 standard, which elucidates the evaluation concept of Whole Body Vibration. First of all, the ride speed component, which significantly affects the amplitude of the vibration experienced in the vehicle, was determined. In this context, vibration data were recorded at three different points in the vehicle at 20, 30, 40, and 50 km/h ride speeds on a road section whose roughness can be considered homogeneous. Measurements were repeated with drivers weighing 58, 80, and 113 kg to determine the effect of driver weight on vibration parameters. The vibration parameters produced due to the analyses were evaluated with both parametric and non-parametric statistical methods. In the urban road network with bituminous hot mixture pavement, it has been determined that the most appropriate ride speed for passenger car-type vehicles to evaluate the service level of the pavement is 40 km/h. In the last stage, the differences between the averages of the measurements made with three different weight drivers at the determined ride speed were evaluated statistically. Through analysis of three distinct data recording points within the vehicle, it has been established that the driver's weight exerts no discernible influence on any of the vibration parameters.

Authors: KOMAN Hakan
Published: March 2024

In this study, the effect of two different wall systems which are composed of the structural lightweight concrete panel and metallic elements between the wall and frame on the behaviour of the RC frame is investigated numerically by using the Abaqus software. In the second type of wall system, a polyurethane-based binder was used between the wall and the RC beam. A quasi-static lateral loading was applied to 5 different full scale RC frames with and without walls, and frames were pushed 80mm laterally. In the worst case, the wall system carried 1.52 times the lateral load bare frame carried, whereas in the best case, the frame with the wall system carried 2.12 times the load bare frame carried. When thinner metallic elements were used, the elements yielded. This is promising for increasing damping in structures also. The second type of wall which interacts with the beam increased the initial lateral stiffness of the frame by 156% when compared with the bare frame. All frames conducted a ductile behavior and bare frame results are validated by comparing with previous study.

Bu çalışmada PA6 ve PA610 harmanlanmış ve bu karışıma özelliklerini iyileştirmek amacı ile cam elyaf (GF) ve lignin (LL) eklenmiştir. Kompozitler ekstrüzyon ve enjeksiyon kalıplama yöntemleriyle hazırlanmış ve morfolojik, ısıl (diferansiyel taramalı kalorimetre-DSC, termogravimetrik analiz-TGA) ve yanmazlık (sınırlayıcı oksijen indeksi-LOI, dikey yanma testi-UL-94, konik kalorimetre), özellikleri incelenmiştir. GF takviyeli kompozitte iyi bir arayüzey etkileşimi ve homojen dağılım gözlenirken, LL’nin matris ile etkileşiminin zayıf olduğu görülmüştür. GF matrisin ısıl karalılığını iyileştirmiş ve kalıntı miktarını yükseltmiştir. GF/LL kompozitlerinde ise LL ısıl dayanımı düşürse de kütle kayıp hızını yavaşlatmış ve kalıntı miktarını artırmıştır. GF ve LL ilavesi ile matrisin erime noktasında belirgin bir değişim olmazken LL kristalizasyon sıcaklığını düşürmüş ve dolayısıyla matrisin kristalinitesini büyük oranda azaltmıştır. Matrisin LOI değeri ve UL-94 sınıflandırmasında GF ilavesi ile bir gelişim olmazken, LL’nin yanma süresini belirgin bir şekilde kısalttığı gözlenmiştir. PA6/PA610’a eklenen GF ve LL matrisin maksimum ısı salınım hızı, toplam ısı salınım değerlerinde önemli ölçüde düşüş sağlayarak kompozitin yanmazlık özelliğini geliştirmiştir. Sonuç olarak bu çalışma GF takviyeli PA kompozitleri için ligninin etkin bir alev geciktirici olduğunu göstermiştir.

Authors: AYRANPINAR İrem , KOZAK Melike , GÖÇER Serdar , CIRIK Kevser
Published: March 2024

Textile wastewater has a complex composition characterized by high dye content and chemical oxygen demand. Therefore, textile wastewaters have serious environmental impacts, such as aesthetic degradation, and carcinogenic properties. Treatment and the recovery of textile wastewater are important due to their high volume and toxicity. The effects of peroxidase enzyme immobilized on magnetic chitosan-clay beads of synthetic textile wastewater were investigated in a batch reactor. System performance was determined by chemical oxygen demand (COD) and color. The batch reactor was operated in three different pH (5, 7, 10), temperatures (25, 35, 45 °C), and reaction times (0-5-10-20-30 min.) with synthetic textile wastewater. As a result, COD and color removal efficiencies were determined as 44% and 56%, respectively, corresponding effluent concentrations are 1442 mg/L, 450 Pt-Co. The results of this study show that using the enzyme immobilization process is an effective method to remove color and COD concentration from textile wastewater.
Carbon Emissions Trading Scheme's Disproportionate Abatement Costs on Developing Nations: Evidence from the Korea ETS
Authors: Hwang Sean
Published: March 2024

This research paper delves into the intricate dynamics of Carbon Emissions Trading Schemes (ETS), emphasizing the environmental injustices embedded in their implementation, particularly with re-spect to the disproportionate financial and economic impacts on developing countries. Centered on the case of South Korea's ETS, the paper employs a comprehensive case study to unveil nuanced in-sights into how these schemes influence the competitiveness of industries in nations undergoing eco-nomic development. Employing rigorous econometric analysis, the study scrutinizes the alloca-tion of CO2 ETS permits across various sectors, revealing significant disparities in the distribution of abatement costs. The findings underscore the multifaceted challenges of formulating global climate policies that effectively reconcile the need for environmental sustainability with the economic constraints faced by developing nations. This paper advocates for a more nuanced and equitable ap-proach to international climate action, suggesting modifications to ETS frameworks that better ac-count for the distinct developmental stages and economic vulnerabilities of these countries. By urging a shift towards an approach that acknowledges and addresses these complexities, the re-search contributes significantly to the ongoing discourse surrounding the formulation of inclusive, ef-ficacious, and just global environmental policies.

Published: March 2024

To investigate the consequence of thermophoresis and Brownian diffusion on convective boundary layer micropolar fluid flow over a stretching wedge-shaped surface. The effects of
non-dimensional parameters namely coupling constant parameter (0.01 ≤ B1 ≤ 0.05), magnetic parameter (1.0 ≤ M ≤ 15.0), Grashof number (0.3 ≤ Gr ≤ 0.9), modified Grashof number
(0.3 ≤ Gm ≤ 0.8), micropolar parameter (2.0 ≤ G2 ≤ 7.5), vortex viscosity constraint (0.02 ≤ G1 ≤ 0.2), Prandtl number (7.0 ≤ Pr ≤ 15.0), thermal radiation parameter (0.25 ≤ R ≤ 0.50), Brownian motion parameter (0.2 ≤ Nb ≤ 0.62), thermophoresis parameter (0.04 ≤ Nt ≤ 0.10), heat generation parameter (0.1 ≤ Q ≤ 0.5), Biot number (0.65 ≤ Bi ≤ 1.0), stretching parameter (0.2 ≤ A ≤ 0.5), Lewis number (3.0 ≤ Le ≤ 7.0), and chemical reaction parameter (0.2 ≤ K ≤ 0.7) on the steady MHD heat and mass transfer is investigated in the present study. The coupled non-linear partial differential equations are reduced into a set of non-linear ordinary differential equations employing similarity transformation. Furthermore, by using the Runge-Kutta method followed by the shooting technique, the transformed equations are solved. The main goal of this study is to investigate the numerical analysis of nanofluid flow within the boundary layer region with the effects of the microrotation parameter and velocity ratio parameter. The novelty of this paper is to propose a numerical method for solving third-order ordinary differential equations that include both linear and nonlinear terms. To understand the physical significance of this work, numerical analyses and tabular displays of the skin friction coefficient, Nusselt number, and Sherwood number are shown. The new approach of the present study contributes significantly to the understanding of numerical solutions to non-linear differential equations in fluid mechanics and micropolar fluid flow. Micropolar fluids are becoming even more of a focus due to the desire for engineering applications in various fields of medical, mechanical engineering, and chemical processing.

Published: March 2024

Design of economical and effective solar ponds which are useful thermal energy storage devices, remains a huge challenge. The present work aims at investigating the thermal performance of low cost mini salt gradient solar pond. The portable pond was fabricated as a rectangular configuration having a volume of 0.5m3. Polystyrene and high density polyethylene sheets were employed for insulating the walls. The top of the pond was covered with a slender glass so that the dust accumulation could be prevented without affecting the absorption of solar radiation. Sodium chloride salt was used as the medium and the three salt gradient regions namely lower convective, non-convective, and upper convective regions were established through injection filling technique. The temperature and salt gradient data were observed experimentally for a period of 20 days at Coimbatore, India. The pond could absorb significant amount of available radiation (around 65%) and the maximum temperature of the pond was observed to be 49oC. Frequent washing of the water surface is necessary to maintain stable salt gradient. Nevertheless, portable pond fabricated with low cost materials exhibited good potential of storing solar energy for solar thermal applications.

Published: March 2024

The paper aims to suggest the ranking of an optimal solution when there exists more than one Nash equilibrium in the game theory solution concept. Many studies tend to merge the game theory with the multi criteria decision-making (MCDM) method to cater the real-situation problems. In the paper, a novel hybrid non-cooperative static game in game theory is combines with the trade-off ranking (TOR) method in MCDM. The proposed hybrid method is used to rank multiple Nash equilibria concerning some criteria. The methodology for both static game and TOR method are explained in the paper. The game theory model used is a two-player non-constant-sum static game. The proposed methodology is tested using international cooperation in Iran. The result suggests the ranking of the combined strategies using the proposed method.

Published: March 2024

This study describes the implementation of public service innovations (“Healthy Alley” and home care) in Makassar to disclose facts about the factors supporting innovations so that they can be sustainable in the future. Data were collected through a structured interview process with 14 informants and through observation by researchers. Secondary data were collected from national journal articles and annual report documents from the Department of Health, Makassar Regional Development, and Research Agency. Validity and reliability were addressed by triangulating data sources. Out of five innovation attributes, the “Healthy Alley” and home care innovations only met four standards. The research findings revealed that the home care innovation program has been well implemented compared to the "Healthy Alley" innovation program. This condition was due to the two different innovation programs in the handling system. The sustainability of public service innovation can be realized by taking into account several supporting indicators: 1. Commitment of Implementor; 2. User Participation; 3. Supported; 4. Network. Also, it is known that a public service innovation program with a good handling system will succeed in improving the quality of public service policies that affect innovation, but the budget will make things easier.
Indonesia's National Capital Relocation Policy: An Analysis of Political Support in Parliament and the Public Responses on Twitter
Authors: Ikfina Muhammad Ulfi
Published: March 2024

This study aims to explain the policy of relocating Indonesia's capital city from the perspective of political support in parliament and public response on Twitter. This research used a qualitative method with a case study approach. The findings revealed that the policy of relocating the National Capital (IKN) in quantity has received dominant political support in parliament. Eight of the nine political parties with parliament seats agreed to approve the policy. However, at the beginning of the plan to relocate the national capital, the government, as the initiator of the approach, has yet to gain political support in parliament and has minimal communication with the public. Thus, the relocating policy caused a powerful polemic among the people, even in the vortex of the parliamentary elite. Interestingly, the public response on Twitter, content, and narratives turned predominantly positive after circulating explanations from the government regarding the policy. So, public policy and communication are closely related; both must go hand in hand.
