EFL teachers’ awareness and attitudes towards personal and impersonal metadiscourse markers in L2 academic writing
Karakuş, Nursevinç.; Sağın Şimşek, Sultan Çiğdem; Department of English Literature (2020)
The purpose of the current study is to investigate EFL instructors’ awareness and attitudes towards personal and impersonal metadiscourse markers in L2 academic writing. Thirteen EFL instructors who have at least five years of teaching experience in a state university participated in the study. This study is designed as a qualitative study. To this end, semi-structured interviews were conducted as a data collection tool. Prior to the interviews, a handout that contains jumbled sentences with personal and im...
Biodegradation of nonylphenols, determination of degradation products and detection of responsible microorganisms using molecular techniques
Kara Murdoch, Fadime; Sanin, Faika Dilek; Gültekin, Güzin Candan; Department of Biotechnology (2015)
Nonylphenol(poly)ethoxylates (NPnEO) have received special attention during the last decades due to their toxic and endocrine-disrupting effects for many organisms. They have limited degradation in wastewater treatment plants especially in activated sludge units. Since they accumulate in sludge, understanding of their fate during sludge treatment is important. With this motivation, this research aimed to monitor the degradation of nonylphenol diethoxylate (NP2EO, as a parent compound) into its degradation p...
Biodegradable Elastomeric Networks: Highly Efficient Cross-Linking of Poly(trimethylene carbonate) by Gamma Irradiation in the Presence of Pentaerythritol Triacrylate
Bat, Erhan; Grijpma, Dirk W. (2010-10-01)
Biodegradable elastomeric poly(trimethylene carbonate) (PTMC) networks were efficiently formed by gamma irradiating the linear polymer in the presence of pentaerythritol triacrylate (PETA). The properties of networks formed upon irradiation of PTMC films containing (0.1.5 wt %.) PETA as cross-linking aid were evaluated. The gel contents and network densities increased with increasing PETA contents, irradiation dose, and initial polymer molecular weight. At a dose of 25 kGy, networks with gel fractions up to...
Nonlinear optical properties of semiconductor heterostructures
Yıldırım, Hasan; Tomak, Mehmet; Department of Physics (2006)
The nonlinear optical properties of semiconductor heterostructures, such as GaAsAl/GaAs alloys, are studied with analytic and numerical methods on the basis of quantum mechanics. Particularly, second and third-order nonlinear optical properties of quantum wells described by the various types of confining potentials are considered within the density matrix formalism. We consider a Pöschl-Teller type potential which has been rarely considered in this area. It has a tunable asymmetry parameter, making it a goo...
Biotransformation of the Fluorinated Nonsteroidal Anti-Inflammatory Pharmaceutical Flurbiprofen in Activated Sludge Results in Accumulation of a Recalcitrant Fluorinated Aromatic Metabolite
Yanac, Kadir; Murdoch, Robert Waller (2019-06-01)
Flurbiprofen is a fluorinated, nonsteroidal, anti-inflammatory pharmaceutical with potential application in a wide range of maladies. Currently, there is no information regarding its environmental fate. To address this, flurbiprofen is spiked at 500 and 50 ppm into activated sewage sludge taken from the municipal treatment plant of Ankara, Turkey. Flurbiprofen is partially degraded after 80 days, with removal proportion varying from 33% to 48%. Isolation of organisms able to use flurbiprofen as a sole carbo...
