Commissioning of the vacuum system of the KATRIN Main Spectrometer
2016
The KATRIN experiment will probe the neutrino mass by measuring the β-electron energy spectrum near the endpoint of tritium β-decay. An integral energy analysis will be performed by an electro-static spectrometer (``Main Spectrometer''), an ultra-high vacuum vessel with a length of 23.2 m, a volume of 1240 m[superscript 3], and a complex inner electrode system with about 120 000 individual parts. The strong magnetic field that guides the β-electrons is provided by super-conducting solenoids at both ends of the spectrometer. Its influence on turbo-molecular pumps and vacuum gauges had to be considered. A system consisting of 6 turbo-molecular pumps and 3 km of non-evaporable getter strips ha…
Case Management for Depression by Health Care Assistants in Small Primary Care Practices
2009
BACKGROUND: Case management by health care assistants in small primary care practices provides unclear benefit for improving depression symptoms. OBJECTIVE: To determine whether case management provided by health care assistants in small primary care practices is more effective than usual care in improving depression symptoms and process of care for patients with major depression. DESIGN: Cluster randomized, controlled trial. A central automated system generated the randomization scheme, which was stratified by urban and rural practices; allocation sequence was concealed until groups were assigned. SETTING: 74 small primary care practices in Germany from April 2005 to September 2007. PATIEN…

Application of data mining techniques to indoor and outdoor air studies

Humans emit a wide range of volatile organic compounds (VOCs). These molecules can be emitted via breath and skin and can be from endogenous or exogenous sources. The main breath gases besides N2 and O2 include CO2, acetone and isoprene and are mainly endogenously produced via metabolic pathways. Exogenously emitted molecules comprise methanol from the digestion of fruits and molecules such as monoterpenes and siloxanes used in hygiene products. The study of these human-made emissions is important for the detection of biomarkers for illnesses as well as for the estimation of the contribution of human emission to indoor and outdoor environments. The measurement of volatile organic compounds …
