A hemispheric dust storm affecting the Atlantic and Mediterranean in April 1994: Analyses, modeling, ground-based measurements and satellite observations
Ozsoy, E; Kubilay, N; Nickovic, S; Moulin, C (American Geophysical Union (AGU), 2001-08-27)
One of the largest recorded dust tranpsort events originating from the great Sahara desert during April 1994 affected the entire region extending from the Caribbean to the Eurasian continent. This hemispherical transport of airborne dust took place during a series of storms that developed during the first three weeks of April in a background of low-index circulation. These repeated events are studied through the combined analyses and interpretation of atmospheric data, ground-based aerosol measurements, vis...
The new chemicals policy of the eu and its environmental implications on EU and Turkey
Bacakoğlu, Zeliha; Güneş, Şule; Department of European Studies (2016)
This thesis aims at analysing the REACH Regulation which constitutes the backbone of the New Chemicals Policy of the EU in the context of the environmental framework. Related to that aim, basic instruments of the Regulation are considered in order to clarify what kind of health and environmental benefits to be obtained with them. Secondly, the EU-Turkey relations is examined with its twofold nature under the Customs Union and candidacy process by seeking an answer to the question of possible legislative and...
A chemical substitution study for a wet processing textile mill in Turkey
Öztürk, Ertan; Demirer, Göksel Niyazi; Department of Environmental Engineering (2007)
The main environmental concern in the textile industry is about the amount of water discharged and the chemical load it carries. The total quantity of chemicals used in textile mills varies from 10% to over 100% of the weight of the cloth produced. Many chemicals currently used in the textile industry affect the amount and the type of waste produced and their influence the aquatic life of the receiving stream. One of the critical steps in pollution prevention studies is auditing the use of chemicals and mak...
A Laboratory Column Investigation for the Treatment of Cr(VI) with Zero-Valent Iron
Uyusur, Burcu; Ünlü, Kahraman (Mary Ann Liebert Inc, 2009-02-01)
Permeable reactive barrier (PRB) technology is commonly placed in the list of options for groundwater remediation at hazardous waste sites, where Cr(VI) treatment in groundwater has been a concern more than any other inorganic contaminants. The objective of this study was to investigate the effectiveness and longevity of Cr(VI) removal with zero-valent iron based PRBs. The main focus was on two parameters affecting the performance of Cr(VI) removal with PRBs: (1) amount of reactive media and (2) groundwater...
A Modular Superconducting Generator for Offshore Wind Turbines
Keysan, Ozan; Mueller, Markus A (2013-05-01)
In this study, a new claw-pole type transverse flux superconducting generator topology is presented. The machine has a stationary superconducting field winding, which eliminates electrical brushes and cryocouplers. The machine is specifically designed for low-speed high torque applications such as large offshore wind turbines. The proposed machine is robust and has a modular structure.
