본 연구에서는 EPP(Expanded polypropylene) 준정적 및 충격 하중에 대한 구성방정식을 표현하는 데 있어서, 충격량-운동량 이론을 연계하였다. 또한, 구성방정식을 이루는 물리적으로 의미있는 변수들에 대해, 상대밀도의 함수로 표현하였다. 이를 위해, 연립 비선형 뉴튼-랩손 방법을 사용하여, 준정적 시험결과에 맞는 구성방정식의 변수값을 선정하였다. 또한, 충격량-운동량 이론이 구성방정식과 연계되어, 충격시 응력-변형률 선도를 변형률 속도에 따라 구하였고, 충격시험결과와 비교하였다. 향후에는 다른 재질의 발포고분자에도 본 구성방정식이 적용될 수 있을 것…
Photocatalytic oxidation nowadays has been pledging as the valuable process for air and water purification because of its capability to degrade organic pollutants. Photodegradation of organic pollutants by suspended photocatalyst have major drawbacks in terms of difficulty in post-recovery treatment. In this study, po…
We show high-temperature ferromagnetism in heavily Fe-doped ferromagnetic semiconductor (Ga1-x,Fex)Sb (x = 23% and 25%) thin films grown by low-temperature molecular beam epitaxy (LT-MBE). Our crystal structure analysis by scanning transmission electron microscopy (STEM) indicates that the (Ga1-x,Fex)Sb thin films mai…
Environmental barrier coatings (EBC) are considered mandatory for the application of ceramic matrix composites (CMC) in hot sections turbine engines such as combustors. Low thermal mismatch, good adherence, microstructural stability and resistance against hot corrosion are key material properties. Y2O3-stabilized ZrO2…

Melt-conditioned direct chill (MC-DC) casting process is a novel billet casting technology developed recently for enhanced the grain refinement of cast billet without any grain refiner required. Present work endeavours to understand the behaviour of various parameters of rotor-stator based shearing device on the liqui…
The objective of this work was to evaluate toxicity induced by silica-coated ION on a human neuronal cell line (SHSY5Y).
Σκοπός της μελέτης είναι η αξιολόγηση του συνδυασμού αντιοξειδωτικών φαρμακευτικών ουσιών Ν-ακετυλοκυστεΐνη (NAC) και Δεφεροξαμίνη (DFO) κατά την ανάταξη της αιμορραγικής καταπληξίας σε χοίρειο πειραματικό μοντέλο αιμορραγίας σε ηπατεκτομή. Μέθοδοι: Για τη διεξαγωγή της πειραματικής μελέτης χρησιμοποιήθηκαν 21 χοίροι.…
Silicon carbide particle reinforced aluminum matrix (Al) composites have been developed over past few decades, owing to their excellent properties like lightweight, high elastic modulus and wear resistance. Thus, the silicon carbide (SiC) particle reinforced Al composites are expected to have many applications in aero…
Composite is a combination of two or more constituent materials, when two materials with a different properties were combined, it produces a material which has superior properties than a single material. Natural fibers can be defined as a fiber that produces by a plant or animal, which is categorized as a renewable re…
Aubry-André-Harper lattice models, characterized by a reflection-asymmetric sinusoidally varying nearest-neighbor tunneling profile, are well known for their topological properties. We consider the fate of such models in the presence of balanced gain and loss potentials ±iγ located at reflection-symmetric sites. We pr…
Push-pull π-conjugated systems of the thiophene type have several interesting applications as nonlinear optical (NLO) and photochromic materials, sensitizers for dye sensitized solar cells (DSSCs), etc. As part of an on-going research to develop efficient donor-acceptor substituted heterocyclic systems for diverse app…

This study aims to design and develop effervescent proliposomes that could disintegrate in water and liberate liposomes, and to investigate the potential suitability of liposomes generated for aerosolization to target paranasal sinuses. Novel effervescent proliposomes prepared with Soya phosphatidylcholine (SPC) and D…
This thesis deals with material selection and design selection of high performance floating brake calliper. The main function of brake system is to decelerate or stop a car. Disc brake system consist of brake rotor, brake pads and brake calliper. Most of the commercial vehicles use brake calliper made of Gray cast iro…

This thesis deals with measurement of liquid contact angle with different surface roughness. The objective of this thesis is to measure the contact angle on different material of solid surfaces and to measure the effect of surface roughness to the shape of liquid drop from above view. Sessile drop method is used in th…
The issues on increasing utilization of waste materials from industry such as palm oil fuel ash and cockle shell during concrete production to meet the continuous demand of the construction industry has led towards efforts of using any waste material as partial replacement in this composite material. Nowadays, sand ha…
Polymer consist of the long chain molecules constructed of atoms (such as carbon and hydrogen) in the various arrangements with the different elements in the forming of basic building block of a polymer chain. Besides that, natural fiber reinforced polymer composite has a huge affinity to replace the composite made up…
Η παρούσα διατριβή έγινε με σκοπό τη μελέτη της ba3 οξειδοαναγωγάσης απομονωμένης από το βακτήριο Thermus thermophilus με φασματοσκοπία υπερύθρου με μετασχηματισμό Fourier με χρονική ανάλυση. Η ba3 οξειδοαναγωγάση έχει τρείς ζωτικής σημασίας λειτουργίες, καταλύει την αναγωγή του οξυγόνου σε νερό, την αναγωγή του μονοξ…
