Uç Değerler Teorisi ve Riske Maruz Değer
(Fen Bilimleri Enstitüsü, 2014)Value-At-Risk (VaR) is a method, measures the maximum loss of the investment for a given confidence interval and holding period. When the classical VaR models are analyzed, it is shown that these models are based on the ... -
Uç Değerler Teorisi ve Türkiye Deprem Verisi Üzerine Bir Uygulama
(Fen Bilimleri Enstitüsü, 2015)In this study, Extreme Value Theory (EVT) has been studied broadly. In practice, contrary to the popular applications (hydrology, meteorology, economy, etc.) we did an analysis of the seismic data which is new in the Turkish ... -
Ulaşım Sektörünün Düşük Karbon Ekonomisine Geçişteki Rolünün Analizi
(Fen Bilimleri Enstitüsü, 2020)Emissions from transportation play a significant role in the deterioration of air quality and human health. In our country, greenhouse gas emissions (GHG) from the transportation sector increased by 132% in 2000-2017 and ... -
Ultra Viyole (Uv-B)Stresinin Bazı Sarıçam (Pinus Sylvestris L.) Soylarına Etkilerinin Araştırılması
(Fen Bilimleri Enstitüsü, 2014)Amount of UV-B radiation reaching to earth s surface is increase day by day because of depletion of ozone layer. The increase in the amount UV-B radiation affects negatively growth and development of plant.UV-B radiation ... -
Ultrasensitive Detection And Quantification Of Acidic Disaccharides Using Capillary Electrophoresis And Quantum Dot-Based Fluorescence Resonance Energy Transfer
(Amer Chemical Soc, 2013)Rapid and highly sensitive detection of the carbohydrate components of glycoconjugates is critical for advancing glycobiology. Fluorescence (or Forster) resonance energy transfer (FRET) is commonly used in detection of ... -
Uluslararası Alg Mantar ve Bitki Adlandırma Yasası
(Hacettepe Üniversitesi, 2015)Canlıları sınıflandırmada moleküler verilerin ağırlık kazandığı ve filogenetik araştırmaların daha da güncel olduğu bu dönemde, geleneksel taksonomi bugün de yaşambilimin omurgası niteliğindedir. Yeryüzündeki biyoçeşitliliğin ... -
Uniform Ergodicities And Perturbation Bounds Of Markov Chains On Ordered Banach Spaces
(Iop Publishing Ltd, 2017)In this paper, we consider uniformly mean ergodic and uniformly asymptotical stable Markov operators on ordered Banach spaces. In terms of the ergodicity coefficient, we show the equivalence of uniform and weak mean ... -
Universal Modules of Differantial Operators
(Fen Bilimleri Enstitüsü, 2015)This thesis is concerned with universal differential operator modules of order n. Let R be a commutative k-algebra where k is an algebraically closed field of characteristic zero. Let m and n be positive integers such that ... -
Unliganded Estrogen Receptor-Alpha Activates Transcription Of The Mammary Gland Na+/I- Symporter Gene
(Academic Press Inc Elsevier Science, 2006)The function of sodium iodide symporter (Na+/I- symporter, or NIS) in mammary epithelial cells is essential for the accumulation of I- in milk; the newborn's first source of I- for thyroid hormone synthesis. Furthermore ... -
Unveiling Cryptic Species Of The Bumblebee Subgenus Bombus S. Str. Worldwide With Coi Barcodes (Hymenoptera: Apidae)
(Taylor & Francis Ltd, 2012)Bumblebees of the subgenus Bombus s. str. dominate (or used to dominate) many north temperate pollinator assemblages and include most of the commercial bumblebee pollinator species. Several species are now in serious ... -
Updates On The Distribution And Diversity Of Sand Flies (Diptera: Psychodidae) In Romania
(2019)Background Phlebotomine sand flies (Diptera: Psychodidae) are haematophagous insects that transmit the protozoan parasite Leishmania infantum (Kinetoplastida: Trypanosomatidae), the main causative agent of both zoonotic ... -
Upper Branch Nonstationary Modes Of The Boundary Layer Due To A Rotating Disk
(Pergamon-Elsevier Science Ltd, 2001)A treatment of asymptotic calculation of upper branch nonstationary instsability modes is undertaken in the boundary layer flow due to a. rotating disk. A numerical spectral solution of the eigenvalue problem shows good ... -
Using Next-Generation Dna Sequence Data For Genetic Association Tests Based On Allele Counts With And Without Consideration Of Zero Inflation
(2016)The relationship between genetic variability and individual phenotypes is usually investigated by testing for association relying on called genotypes. Allele counts obtained from next-generation sequence data could be used ... -
Using Non-Traditional Writing As A Tool In Learning Chemistry
(Eurasia, 2013)This study investigated the effect of using a non-traditional writing task and different audiences on 9th grade students' conceptual understanding of a chemistry unit on mixture. 524 students instructed by 3 chemistry ... -
Using Of Nanofiber Based Electrodes For Detection Of Organic Molecules
(Fen Bilimleri Enstitüsü, 2018)The disposable electrodes of the diabetes sensors used in our country are in the case of external dependency due to the necessity of importation. In addition, these types of electrodes are only capable of measuring the ... -
