CURRENT STATUS AND THE FUTURE PROJECTIONS OF THE TURKISH PELLET FUEL INDUSTRY: A SURVEY STUDY
Karaca, Neşet Kutay; Özdemir, Özlem; Department of Business Administration (2021-7-30)
As of 2019, Turkey has 22 million 740 thousand hectares forest assets nationwide and ranks at 31st worldwide; which positions Turkey as a potential large volume pellet fuel producer. Turkey has the potential to become a more important producer and consumer on global pellet fuel markets if certain strategic actions be taken. This thesis study aims to elaborate the current status of the Turkish pellet fuel industry and to explore the main opportunities and challenges facing the industry's future development w...
Estimation of wheat yields by using remotely sensed and modeled agro-meteorological data-driven statistical and crop growth models
Bulut, Burak; Yılmaz, Mustafa Tuğrul; Department of Civil Engineering (2021-6)
Estimation of wheat yield is essential not only for agricultural sectors but also for making economic and strategic decisions at the national level. In this thesis, wheat yield estimation was carried out on the cities and districts where the highest wheat production is made with rainfed agriculture in Turkey and on TİGEM research farms. Two different modeling approaches were evaluated within the scope of the thesis; a statistical multiple linear regression (MLR) model based on analysis of possible agro-mete...
SERICIN PROTEIN RECOVERY FROM SILK DEGUMMING WASTEWATER IN PILOT SCALE VIA MEMBRANE HYBRID PROCESSES
Gençtürk, Merve; Yetiş, Ülkü; Çapar, Gökşen; Department of Environmental Engineering (2021-5-17)
The conventional degumming method that consists of alkaline washing of silk yarn with Marseille soap at high temperatures, dissolves sericin protein into the water and produces so-called silk degumming wastewater (SDW) which is rich in sericin protein. In this study, the separation of sericin protein from the SDW was studied. Firstly, the separation of sericin containing phase from the SDW was optimized. SDW samples were prepared with the application of different soap to silk yarn ratios (FO) and tested for...
Determination of phenolic compound profiles and antioxidant effect of black elderberry, echinacea and iceland moss extracts on late-release soft lozenge
Yıldız, Özge; Bayındırlı, Alev; Çapanoğlu Güven, Esra; Department of Food Engineering (2021-6)
Medicinal plants contain different bioactive compounds that have immune system stimulant, anti-inflammatory, antibacterial, antiviral, antifungal, anticancer and wound healing effects. Echinacea purpurea L., Sambucus nigra L. and Cetraria islandica L. are known with their high antioxidant content and health promoting properties. The main objective of the study was to determine the total phenolic content, total flavonoid content and antioxidant capacity of each plant extract with water and 75 % ethanol as so...
SILVER-PLATINUM CORE-SHELL NANOWIRES FOR ELECTROCHEMICAL APPLICATIONS
Tunca, Şensu; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2021-7)
Silver nanowire (Ag NW) networks are one of the most outstanding candidates for optoelectronic applications to replace the commercial transparent conducting oxides (TCOs). Their high mechanical stability, solution based and scalable, low-cost synthesis and deposition routes make them an advantageous candidate over TCOs for future electronics. However, the integration of NW networks into electronic devices requires high thermal, chemical and electrochemical stability of NWs. This work describes the fabricat...
