Use of Lawesson's reagent in organic syntheses


Application of nonlinear unit root tests and threshold autoregressive models
Uysal, Ela; Yıldırım Kasap, Dilem; Department of Economics (2012)
Popularity of nonlinear threshold models and unit root tests has increased after the recent empirical studies concerning the effects of business cycles on macroeconomic data. These studies have shown that an economic variable may react differently in response to downturns and recoveries in a business cycle. Inspiring from empirical results, this thesis investigates dynamics of Turkish key macroeconomic data, namely capacity utilization rate, growth of import and export volume indices, growth of gross domest...
Numerical modeling of re-suspension and transport of fine sediments in coastal waters
Karadoğan, Erol; Özhan, Erdal; Department of Civil Engineering (2004)
In this thesis, the theory of three dimensional numerical modeling of transport and re-suspension of fine sediments is studied and a computer program is develped for simulation of the three dimensional suspended sediment transport. The computer program solves the three dimensional advection-diffusion equation simultaneously with a computer program prepared earlier for the simulation of three dimensional current systems. This computer program computes the velocity vectors, eddy viscosities and water surface ...
Seismic response of a rubble mound breakwater in Turkey
Yuksel, Y; Çetin, Kemal Önder; Ozguven, O; Isik, NS; Cevik, E; Sumer, BM (Thomas Telford Ltd., 2004-12-01)
This paper presents analyses of seismically induced deformations at Eregli Fishery Port breakwater during the 1999 Kocaeli (Izmit), Turkey earthquake. The paper discusses: (a) observed ground deformations and displacements after the earthquake; (b) the results of field investigations by means of borings including standard penetration tests; (c) analyses of observed deformation mechanisms by a suite of methods; and (d) the possible contribution of soil liquefaction rupture on the observed deformations.
Synthesis of Chlorotoxin by Native Chemical Ligation
KARACA, Ulvi; Özçubukçu, Salih (2018-04-01)
Chlorotoxin (CLTX) is a neurotoxin found in the venom of the Israeli scorpion, Leirius quinquestriatus. It contains 36-amino acids with four disulfide bonds and inhibits low-conductance chloride channels. CLTX also binds to matrix metalloproteinase-2 (MMP-2) selectively. The synthesis of chlorotoxin using solid phase peptide synthesis (SPPS) is very difficult and has a very low yield (<1%) due to high number of amino acid sequence. In this work, to improve the efficiency of the synthesis, native chemical li...
Application of ultrasonic burning rate measurement method on closed bombs
Mumcu, Berkan; Kurtuluş, Dilek Funda; Arkun, Uğur; Department of Aerospace Engineering (2013)
In this thesis study, detailed information about solid rocket motors and ultrasonic burning rate measurement method is given. An experimental setup is prepared for applying the ultrasonic burning rate measurement method. Before performing the burning tests, some pre-tests are performed for affirming the ultrasonic sensor and obtaining some experimental coefficients. Two different types of propellants, which do not include aluminum, are produced for the burning tests. The first type of the propellants has tw...
