The application of aliminum foam for the heat and noise reduction in automobiles
Thesis (Master)--Izmir Institute of Technology, Mechanical Engineering, Izmir, 2005Includes bibliographical references (leaves: 77-81)Text in English; Abstract: Turkish and Englishxiv, 91 leavesAn experimental study has been conducted to investigate the effective thermal conductivity and sound absorption coefficient of Al and SiCparticle/Al closed-cell foams.The foams were prepared using the foaming of powder compact processes developed by Fraunhofer CMAM. The foaming of powder compact process has been extended for the foaming of composite compacts containing 10 weight percent of SiC particles. Effective thermal conductivity measurements were performed using the temperature distribution for steady state conduction through a uniform plane wall method. The sound absorption coefficient measurements were conducted using the standing wave ratio method. The effect of hole drilling on the sound absorption coefficient of foams was also investigated. The measured effective thermal conductivities of the foams were also fitted to the previously developed effective thermal conductivity models of metal foams.The effective thermal conductivities of studied Al foams were then expressed as function of percent porosity with the best-fitted model equation. The effective thermal conductivity values of Al foams were also compared with those of Alporas closed and ERG open cell foams produced by the foaming of Al melt and investment casting methods, respectively. The sound absorption coefficients of Al and SiC/Al foams were found relatively low and similar at lower relative densities and frequencies. Hole drilling was found to be effective in increasing sound absorption values of foam above400 Hz. The sound absorption in Al and SiC/Al foams was further explained based on the viscous losses and thermal damping effects
Inspection of Defects on Rebar in ReinforcedConcretebyMagneticMeasurementSystem
Rebar is the critical component of the reinforced concrete structures. It is directly related with the
strength of the structure. Rebar protects this strength long-time under appropriate conditions and it
should be inspect properly during its lifetime. In this study, a magnetic system has been constructed to
inspect rebar and also to analyze structure. Several tests and experiments were done on structure with
magnetic system. It was shown that the constructedmagnetic system was succeeded in detecting iron
imperfections and imperfections.Demir donatı, betonarme yapıların kritik bileşenidir. Doğrudan yapının gücü ile ilgilidir. Demir donatı, bu

Foreign Military, Economic, Diplomatic Interventions, and the Termination of Civil Wars: An Integrative Approach
What are the effects of foreign interventions in ending civil conflicts, especially when multiple different intervention types are deployed in a given dispute? Research to date has studied the role of third parties exclusively focusing on a single intervention type at the expense of others. The current project breaks with that tradition by proposing an integrative framework that incorporates various intervention types—military, economic, and diplomatic studies—employed in one conflict.
More specifically, it begins with an interdependence model in which earlier external involvements in a conflict inform subsequent ones, demonstrating that interventions used within a civil war are interrelated with one another. Next, using mathematical models, it generates interventionary patterns in which foreign involvements are sequenced according to their chronological orders, integrating multiple intervention types. Finally, it develops an extended form of bargaining model that accounts for how each interventionary pattern influences civil wars by shifting the power distribution as it also reveals private information in regard to the real capacities of warring parties. Most importantly, the new bargaining framework incorporates the asymmetrical aspects of civil wars, enabling to assess how interventions impact conflict outcomes based on the party they are targeted.
Ultimately, the project concludes that external interventions in any form, regardless of its target, end up with increasing opposition’s capacity while undermining incumbent, including, most conspicuously, any state-sided military assistance. The findings overall highlight the asymmetrical implications of foreign interventions in civil wars and the importance of concerted efforts in terminating these conflicts—a result that is undergirded by the incorporation of multiple interventions into the analysis
collected from South and South-eastern regions of Turkey
A total of 45 lizards (Acanthodactylus harranensis [n = 15], Acanthodacthylus schreiberi [n = 9] and Mesalina brevirostris [n = 21]) were collected from South and Southeastern Regions of Turkey and examined for helminth fauna. Acanthodactylus harranensis harbored 1 species of Nematoda (Skrjabinodon sp.), 1 species of Cestoda (Oochoristica tuberculata) and 1 species of Acanthocephala (Centrorhynchus sp. [cystacanth]). Acanthodactylus schreiberi harbored unidentified cysticercoids. Mesalina brevirostris harbored 1 species of Nematoda (Spauligodon saxicolae). All lizards represents new host records for the helminths reported in this study

Antioxidant, oxidant potentials and element content of edible wild mushroom Helvella leucopus
266-271This study aims to determine the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), DPPH free radical scavenging activity and element levels of the mushroom Helvella leucopus Pers. Ethanol, methanol and dichloromethane extracts of the mushroom samples were obtained using a Soxhlet device. TAS, TOS and OSI values were determined using Rel Assay kits. Cr, Cu, Mn, Fe, Ni, Cd, Pb, and Zn contents were determined using an atomic absorption spectrophotometer. Consequently, this study has demonstrated that H. leucopus has antioxidant potential. As a result of the studies, TAS value of the mushroom was found as 2.181±0.069 mmol/L, TOS value was 14.389±0.170 μmol/L and OSI value was 0.661±0.022. DPPH free radical activity was determined as EtOH extract 49.80±0.71, MeOH extract 44.98±2.18 and DCM extract 23.68±1.37 in 1 mg/mL extract concentration of mushroom. In addition, it was found that the mushroom contains high levels of Pb and Mn. In conclusion, it was found that H. leucopus could be used as a natural agent in pharmacological designs due to its antioxidant activity
