Laboratuvarda Güvenli Çalışma
(Hacettepe Üniversitesi Yayınları, 2015)Kimya olmadan yaşamak mümkün müdür? Cevabı elbette 'hayırdır'. Kimyasal maddeler günlük hayatın bir parçası olmuşlardır. Ancak kimyasal maddelerin üretimi, taşınması, kullanılması ve depolanmasında bazı tehlikeler söz ... -
Large-Scale Purification of a Bacteriocin Produced by Leuconostoc Mesenteroides Subsp Cremoris Using Diatomite Calcium Silicate
(Tubitak Scientific & Technical Research Council Turkey, 2014)Leuconostoc mesenteroides subsp. cremoris strain W3, isolated from wine, was previously found to produce a bacteriocin with inhibitory activity towards malolactic bacteria and hence inhibit malolactic fermentation in model ... -
LDI-MS Analizleri için Etkin ve Seçici Yeni Hedef Yüzeylerin Geliştirilmesi
(Fen Bilimleri Enstitüsü, 2016)Mass spectrometry (MS) is a very important technique that allows components in the sample to be analysed. When the sample is ionized to form positive or negative charged atoms or molecules, their mass/charge ratio can be ... -
Lebesgue and Co-Lebesgue Di-Uniform Texture Spaces
(Elsevier Science Bv, 2009)The author introduces the notions of Lebesgue di-uniformity and co Lebesgue di-uniformity and investigates the relationship between a Lebesgue quasi uniformity on X and the corresponding Lebesgue di-uniformity on the ... -
Legendre Düğümlerin Değişmezleri
(Fen Bilimleri Enstitüsü, 2014)A knot that is everywhere tangent to the contact planes is called a Legendrian knot. There are two types of Legendrian knots in overtwisted contact 3-manifolds: Loose and non-loose Legendrian knots. In the thesis, we study ... -
Legendre Düğümlerinin Sınıflandırılması
(Fen Bilimleri Enstitüsü, 2017)A contact structure on a 3-manifold is a maximally non-integrable 2-plane field distributed all over the 3-manifold. There are two types of contact structures on 3-manifolds: tight and overtwisted. Knots that are everywhere ... -
Legendrian Torus Knots in Lens Spaces
(Scientific Technical Research Council Turkey-Tubitak, 2018)In this study, we first classify all topological torus knots lying on the Heegaard torus in lens spaces, and then we study Legendrian representatives of these knots. We classify oriented positive Legendrian torus knots in ... -
Lepr, Adbr3, Irs-1 And 5-Htt Genes Polymorphisms Do Not Associate with Obesity
(Japan Endocrine Society, 2007)Obesity is a growing problem and is associated with numerous medical conditions. In several genes coding for molecules involved in the regulation of body weight (fat mass) and thermogenesis, polymorphisms have been reported ... -
LES-C Modeli İle Akışkan-Akışkan Etkileşimi Problemlerinde Modelleme Hatasının Azaltılması
(Fen Bilimleri Enstitüsü, 2023)In this study, a numerical method is proposed for a fluid-fluid interaction problem where two flows are coupled through a nonlinear joint interface and one or both of these flows are at high Reynolds numbers. It is known ... -
Life-History Traits of the Invasive Population of Prussian Carp, Carassius Gibelio (Actinopterigi: Cypriniformes: Cyprinidae), from Gelingullu Reservoir, Yozgat, Turkey
(Wydawnictwo Akad Rolniczej W Szczecinie, 2013)Kirankaya S.G., Ekmekci F.G. 2013. Life-history traits of the invasive population of Prussian carp, Carassius gibelio (Actinopterigi: Cypriniformes: Cyprinidae), from Gelingullu Reservoir, Yozgat, Turkey. Acta Ichthyol. ... -
Lineer Olmayan Kısmi Diferansiyel Denklemlerin Backlund Dönüşümleri
(Fen Bilimleri Enstitüsü, 2018)In this thesis, it is studied how the B¨acklund transformations of nonlinear partial differential equations are obtained and deriving new solutions from the known solutions by using these transformations with the ... -
Lipazın Trichoderma Citrinoviride Den Üretimi ve Enzimin Bazı Kinetik Özelliklerinin Saptanması
(Fen Bilimleri Enstitüsü, 2014)In this study, the production of lipase is aimed from a new fungal source that was isolated from soil. Fungi was isolated from soil locality Kocaeli, İlimtepe. Subsequently it was determinated as Trichoderma citrinoviride ... -
Lipid Droplets in Health and Disease
(2017)Lipids are essential building blocks synthesized by complex molecular pathways and deposited as lipid droplets (LDs) in cells. LDs are evolutionary conserved organelles found in almost all organisms, from bacteria to ... -
Lipocalin Gene Expression Is Varied in Developmental Stages by Larval Nutritional Stress in Drosophila
(Tubitak Scientific & Technical Research Council Turkey, 2017)Lipocalin genes NLaz, GLaz, and Karl are evolutionarily conserved genes in Drosophila melanogaster. There are studies on lipocalin gene expression differences under diverse diet conditions, but these studies have focused ... -
LİGAND KATKILI MEZOGÖZENEKLİ SİLİKA KULLANARAK Cu(II) İYONLARININ KOLORİMETRİK TAYİNİ VE ADSORPSİYONU
(Eğitim Bilimleri Enstitüsü, 2018-01)The aim of this work is to evaluate the effectiveness of the ligand dopped mesoporous silica as conjugate materials for Cu(II) ions detection and removal from water samples. In this work, mesoporous monolithic silica was ... -
Long-Time Behaviour of Doubly Nonlinear Parabolic Equations
(Amer Inst Mathematical Sciences-Aims, 2009)We consider a doubly nonlinear parabolic equation in R-n. Under suitable hypotheses we prove that a semigroup generated by this equation possesses a global attractor. -
