Chemical composition of rainwater at EMEP station in Ankara, Turkey
Topcu, S; Incecik, S; Atımtay, Aysel (2002-11-01)
The chemical characteristics of rainfall and its seasonal variation at the EMEP (The Cooperative Programme for Monitoring and Evaluation of the Long-Range Transmission of Air Pollutants in Europe) station located in Cubuk, Ankara were studied for the period between September 1994 and December 1996. The station is located in a rural area about 50 km north of Ankara and is considered as a background station for air pollution. The rainwater samples collected were analyzed for pH, major ions concentrations and ...
Chemical composition of the fine and coarse fraction of aerosols in the northeastern Mediterranean
Koçak, Mustafa; Kubilay, Nilguen (2007-11-01)
Two-stage aerosol samples (PM10-2.5 and PM2.5) were collected at a coastal rural site located in the northeastern Mediterranean, between April 2001 and 2002. A total of 562 aerosol samples were analyzed for trace elements (Fe, Ti, Mn, Ca, V, Ni, Zn, Cr) and water-soluble ions (Na+, NH4+, K+, Mg2+, Ca2+, Cl-, Br-, NO3-, SO42-, C2O42- and 3 4 4 MS-:methane sulfonate). PM10, crustal elements, sea salt aerosols and NO3- were mainly associated with the coarse mode SO42-, C2O42-; whereas non-sea salt (nss) SO42-,...
Chemical composition of Eastern Mediterranean aerosol and precipitation: Indications of long-range transport
Almomani, Idrees; GÜLLÜ, GÜLEN; Ölmez, İlhan; ELER, ÜNAL; Ortel, E; Şirin, Gürol; Tuncel, Süleyman Gürdal (1997-01-01)
Daily aerosol and wet-only precipitation samples were collected, between January 1992 and January 1994 at a permanent station established on the Mediterranean coast of Turkey. Collected aerosol and rain samples were analyzed for major ions and a host of trace elements using a combination of analytical techniques, including ion chromatography, atomic absorbtion spectrometry and instrumental neutron activation analysis. The results have demonstrated;hat concentrations of parameters studied are higher than cor...
Chemical characterization and anticholinesterase effects of essential oils derived from Salvia species
TEMEL, HALİDE EDİP; Demirci, Betul; Demirci, Fatih; CELEP, FERHAT; KAHRAMAN, AHMET; Doğan, Musa; Baser, Kemal Husnu Can (Informa UK Limited, 2016-01-01)
Inhibitory effect of Salvia species herbal preparations on acetylcholinesterase (AChE) and butylcholinesterase (BuChE) activitiy may contribute to regulation of cognitive performance and impaired cholinergic functions in patients with Alzheimer's disease. This functional role of Salvia species and their components makes the investigations on Salvia valuable in medicine-related plant research. Within this work it was aimed to investigate the in vitro anti-cholinesterase effect of essential oils derived from ...
Chemical vapor deposition of boron carbide
Karaman, Mustafa; Özbelge, Önder; Department of Chemical Engineering (2007)
Boron carbide was produced on tungsten substrate in a dual impinging-jet CVD reactor from a gas mixture of BCl3, CH4, and H2. The experimental setup was designed to minimise the effect of mass transfer on reaction kinetics, which, together with the on-line analysis of the reactor effluent by FTIR, allowed a detailed kinetic investigation possible. The phase and morphology studies of the products were made by XPS, XRD,micro hardness and SEM methods. XPS analysis showed the existence of chemical states attrib...
