Abstract

Contains fulltext : 195164.pdf (publisher's version ) (Open Access), Objective: Imaging studies in diffuse low-grade gliomas (DLGG) vary across centers. In order to establish a minimal core of imaging necessary for further investigations and clinical trials in the field of DLGG, we aimed to establish the status quo within specialized European centers. Methods: An online survey composed of 46 items was sent out to members of the European Low-Grade Glioma Network, the European Association of Neurosurgical Societies, the German Society of Neurosurgery and the Austrian Society of Neurosurgery. Results: A total of 128 fully completed surveys were received and analyzed. Most centers (n = 96, 75%) were academic and half of the centers (n = 64, 50%) adhered to a dedicated treatment program for DLGG. There were national differences regarding the sequences enclosed in MRI imaging and use of PET, however most included T1 (without and with contrast, 100%), T2 (100%) and TIRM or FLAIR (20, 98%). DWI is performed by 80% of centers and 61% of centers regularly performed PWI. Conclusion: A minimal core of imaging composed of T1 (w/wo contrast), T2, TIRM/FLAIR, PWI and DWI could be identified. All morphologic images should be obtained in a slice thickness of <= 3 mm. No common standard could be obtained regarding advanced MRI protocols and PET. Importance of the study: We believe that our study makes a significant contribution to the literature because we were able to determine similarities in numerous aspects of LGG imaging. Using the proposed "minimal core of imaging" in clinical routine will facilitate future cooperative studies.

Abstract

23rd European Photovoltaic Solar Energy Conference and Exhibition, 1-5 September 2008, Valencia, Spain; 2492-2493, Transparent conducting oxide (TCO) films play an important role in thin film solar modules. ZnO layers deposited by low pressure chemical vapor deposition (LPCVD) method bring advantages for amorphous and micro crystalline solar cells. Developed and produced by OC Oerlikon, the TCO 1200 mass production system is the first equipment for manufacturing TCO layers with adjustable Light Trapping™ on 1.4 m2 substrates. This paper describes main specifications of the TCO 1200. Growth conditions are easy adjustable leading to high degree of freedom to optimize single layer properties and consequently solar cell performance. It is thus an important tool within thin film solar cell production solutions delivered by OC Oerlikon.
