Hydrogenation of citral over Ni and Ni-Sn catalysts
(TÜBİTAK, 2008-10)Liquid phase citral hydrogenation over zeolite-supported monometallic Ni and bimetallic Ni-Sn catalysts was studied. The zeolite support materials were Na-Y, Na-mordenite, and clinoptilolite. Ni and Sn contents of the ... -
Hydrogenation of citral over Pt and Pt-Sn catalysts
(TÜBİTAK, 2008)Hydrogenation of citral on monometallic (Pt) and bimetallic (Pt-Sn) catalysts was investigated. It was found that the catalyst activities and product distributions were different over Na-Y and Clino supports. Among ... -
Identification of potato Y potyvirus (PVY°) resistance in wild and cultivated tomatoes
(TÜBİTAK, 2009)Potato Y potyvirus (PVY) is an important plant pathogen worldwide that infects and causes yield losses in the family Solanaceae including potato (Solarium tuberosum), pepper (Capsicum spp.), tomato (S. lycopersicum), and ... -
Impacts of transportation projects on urban trends in İzmir
(Turkish Chamber of Civil Engineers, 2008-12)The effects of major transportation projects on urban trends in Izmir were analyzed using the Delphi method. Once convergence was maintained in expert opinions, the Delphi results were re-evaluated according to the suggested ... -
Inequalities for the vibrating clamped plate problem
(TÜBİTAK, 2001)We study the eigenvalues of the vibrating clamped plate problem. We have made improvements on the bounds of the ratios of the eigenvalues of the biharmonic operator (clamped plate) using the methods of Payne, Polya, and ... -
Invadopodia: Proteolytic feet of cancer cells
(TÜBİTAK, 2014)The leading cause of death in cancer patients is metastasis. Invasion is an integral part of metastasis and is carried out by proteolytic structures called invadopodia at the cellular level. In this introductory review, ... -
Investigating the experimental limits of the Brewster’s angle method
(TUBITAK, 2018)We present the method, analysis, and experimental results of the Brewster’s angle method commonly used for determining the refractive indices of optical films. We show the significance of the intersection of reflectance ... -
İzmir’deki ulaştırma projelerinin kentsel eğilimlere etkileri
(TMMOB İnşaat Mühendisleri Odası, 2008)İzmir’deki önemli ulaştırma projelerinin kentsel eğilimlere olan etkileri Delphi yöntemi sonuçları temel alınarak analiz edilmiştir. Delphi yöntemine göre yakınsama sağlanmış etkiler, sonrasında daha anlamlı ve özet ... -
Kablolu bir köprünün deprem davranışının μ-sentezli aktif kontrolü
(TMMOB İnşaat Mühendisleri Odası, 2009)Bu çalışmada çeşitli kontrol algoritmalarının etkinliğini birbiriyle karşılaştırmak amacıyla oluşturulmuş bir kablolu köprü kontrol model örneği [1, 2] baz alınmıştır. Köprünün sonlu elemanlar modeli modal önem sırasına ... -
Kapalı hücreli alüminyum köpük metallerin üretim metodları ve mekanik özellikleri
(TMMOB Metalurji ve Malzeme Mühendisleri Odası, 1999)Kapali hücreli alüminyum köpük metallerin üretim metodları, mikroyapisi, mekanik özellikleri ve uygulama alanları özetlenmiştir. Bu malzemelerin en önemli mekanik özelliklerinden birisi basma altında yüksek miktarda enerji ... -
Kent içi arkeolojik alanlarda katmanlaşmanın analizi ve koruma sorunları: Foça örneği
(Atatürk Kültür, Dil ve Tarih Yüksek Kurumu: Türk Tarih Kurumu, 2018-04)Foça Batı Anadolu’da Prehistorik dönemden başlayarak Arkaik, Klasik, Helenistik, Roma, Bizans, Ceneviz kolonisi ve Osmanlı dönemlerinde sürekli iskân görmüş, çok katmanlı bir yerleşimdir. Kentte arkeolojik kazı çalışmaları ... -
Lateral stiffness of steel bridge I-girders braced by metal deck forms
(American Society of Civil Engineers, 2009)The lateral-torsional buckling capacity of steel bridge girders is often increased by incorporating bracing along the girder length. Permanent metal deck forms (PMDF) that are used to support the wet concrete deck during ... -
Learning control of robot manipulators in the presence of additive disturbances
(TÜBİTAK, 2011)In this paper, a learning controller for robot manipulators is developed. The controller is proven to yield in a semi-global asymptotic result in the presence of additive input and output disturbances. Lyapunovbased ... -
Lebesgue-Stieltjes measure on time scales
(TÜBİTAK, 2009)The theory of time scales was introduced by Stefan Hilger in his Ph. D. thesis in 1988, supervised by Bernd Auldbach, in order to unify continuous and discrete analysis [5]. Measure theory on time scales was first constructed ... -
Metal matrisli kompozitlerin yüksek deformasyon hızlarında davranışları

Modules whose maximal submodules are supplements
(Hacettepe Üniversitesi, 2010)We study modules whose maximal submodules are supplements (direct summands). For a locally projective module, we prove that every maximal submodule is a direct summand if and only if it is semisimple and projective. We ... -
Morphological and molecular identification of pennate diatoms isolated from Urla, İzmir, coast of the Aegean Sea
