Investigating the fracture behaviour of x70m linepipe steel girth weldments via single edge notched tension and bend tests
Tosun, Uygar; Gür, Cemil Hakan; Tirkeş, Süha; Department of Metallurgical and Materials Engineering (2018)
Increasing competition in the global market motivates the producers to invest in novel and cost-effective manufacturing technologies in pipeline construction. Gas metal arc welding multi-pass process has been proven for as-rolled low-alloy steels. Engineering of welding is a special concern in terms of fracture mechanics because the joint yields a fusion line between chemically and physically dissimilar structures. Engineering Critical Assessments (ECA) suggest more realistic scenarios for material’s elasti...
Investigating the performances of photovoltaic modules/systems for Central Anatolia using a thermal modeling approach
Tunçel, Bilge; Akınoğlu, Bülent Gültekin; Department of Physics (2019)
Effective use and performance enhancement of the renewable energy systems are becoming increasingly important as climate change is widely recognized as one of the most crucial problems for the Earth. Turkey, a country within the solar belt, has an abundance of solar energy potential. Economical, environmental and physical investigations are needed to ensure effective utilization of this potential. In this thesis, using the meteorological parameters of the Central Anatolia and parameters of photovoltaic (PV)...
Investigating the methane production efficiency of single- and two-phase anaerobic digestion and population dynamics of a second-phase anaerobic digestion
Koç, Engin; Bayramoğlu, Tuba Hande; Duran, Metin; Department of Environmental Engineering (2015)
The aim of this thesis study was to investigate the methane production efficiency of single-phase and two-phase anaerobic digestion (AD) in batch reactors and anaerobic sequencing batch reactor (ASBR). It was also aimed to monitor the population dynamics and change in the quantity of aceticlastic methane-producers of the second-phase of a two-phase ASBR. Two sets of batch reactors were conducted, namely, Batch Reactor Set-1 and Batch Reactor Set-2. The aim of Batch Reactor Set-1 was to investigate the effec...
Investigating the decision-making skills of cooperating teachers and student teachers of English in a Turkish context
OSAM, ÜLKER; Balbay, Seher (Elsevier BV, 2004-10-01)
Research on decision-making skills of teachers has indicated the importance of experience. Also, occupational culture has been found significantly related to teachers' thinking and behavior in the class. This study investigates in what aspects experienced teachers (cooperating teachers) and less experienced teachers) (student teachers) differ when making instant decisions on diverting from their lesson plans as they teach, and what cultural/institutional influences can be related to these differences. The d...
Investigating the drinking and surface water quality and associated health risks in a semi-arid multi-industrial metropolis (Faisalabad), Pakistan
Mahfooz, Yusra; Yasar, Abdullah; Sohail, Muhammad Tayyab; Tabinda, Amtul Bari; Rasheed, Rizwan; Irshad, Samina; Yousaf, Balal (2019-07-01)
Urban areas under the influence of multi-industrial activities with arid and semi-arid environments witness the significant increase in environmental pollution especially in the water sector. The present study evaluated the water quality and associated health risk assessment through heavy metal pollution. Drinking (n = 48) and surface (n = 37) water samples were collected from semi-arid multi-industrial metropolis, Faisalabad, Pakistan. Physio-chemical and biological parameters and different metals (Al, As,...
