Besides the technical prerequisites for a geothermal use of tunnel waters, there are also other tasks to be completed for a successful utilization. For example, the economic viability needs to be demonstrated for attracting and motivating potential consumers. Moreover, several administrative steps have to be followed to obtain all necessary permits. Nevertheless, the various operating examples in Switzerland demonstrate that all these tasks can be done, even with a relatively low speed of development. At a given location, the... 

A study at the Psychiatric University Hospital in Zurich, Switzerland, demonstrates that psilocybin produces a psychosis-like syndrome in healthy humans that is similar to early schizophrenia. 

Though psilocybin is known as a natural hallucinogen and has a reputation of being gentler than LSD, it is still known to cause panic attacks, bad trips, and to precipitate mental illness in some people. In 1998, a study at the Psychiatric University Hospital in Zurich, Switzerland, demonstrated that psilocybin produces a psychosis-like syndrome in healthy humans that is similar to early schizophrenia. The study showed that psilocybin-induced psychosis was due to serotonin-2A receptor activation and was not dependent on dopamine stimulation. 

In 1993, a report, which helped to understand that conundrum of the KJratio to the high efficacy seen in vivo, was published. Researchers at Ciba-Geigy in Switzerland demonstrated that finasteride is a slow-onset inhibitor of type 2 5AR. However, the rate of inhibition is very slow such that steady-state rates are not reached until 30 min in the presence of 10 nmol 1 finasteride. For finasteride concentrations greater than 10 nmol 1, all progress curves displayed a plateau suggesting complete saturation of the ET complex. Attempts were made to determine a dissociation constant however, the ET complex could not be reactivated after 12 h of dialysis suggesting irreversible inhibition by covalent modification. The authors calculated a revised upper limit of 1 nmol 1 for the value of finasteride, which is more consistent with the clinical results. 

Initial efforts by workers at the Institute for Reference Materials and Measurement (IRMM), Geel, Belgium, to produce certified reference materials for GMOs have demonstrated that the provision of suitable reference materials is not easy and that together with the development of suitable analytical methods there are many challenges to be solved ahead. The first two examples produced jointly by the IRMM in Belgium and Fluka Chemie AG in Switzerland were based on Round-Up Ready Soya and BT 176 Maize. The reference materials are needed to validate EU and Swiss regulations which permit non-GMO products to be contaminated by up to 1 % GMO material and still be accepted. 

Steinfeld et al. [133] demonstrated the technical feasibility of solar decomposition of methane using a reactor with a fluidized bed of catalyst particulates. Experimentation was conducted at the Paul Scherrer Institute (PSI, Switzerland) solar furnace delivering up to 15 kW with a peak concentration ratio of 3500 sun. A quartz reactor (diameter 2 cm) with a fluidized bed of Ni (90%)/Al2O3 catalyst and alumina grains was positioned in the focus of the solar furnace. The direct irradiation of the catalyst provided effective heat transfer to the reaction zone. The temperature was maintained below 577°C to prevent rapid deactivation of the catalyst. The outlet gas composition corresponded to 40% conversion of methane to H2 in a single pass. Concentrated solar radiation was used as a source of high-temperature process heat for the production of hydrogen and filamentous... 

To demonstrate the utility of optophoresis in the preclinical stages of drug discovery, we screened several cell lines for their response to three standard chemotherapy drugs flu-darabine, vincristine, and Gleevec (imatinib mesylate, Novartis Pharmaceuticals, Basel, Switzerland) (Figure 7.6). To perform these measurements with the fast-scan technique, cells were suspended in a 9-mm-diameter well in a sample holder. The bottom surface of... 

Switzerland - the Paul Scherrer Institute demonstrated its PEM technology in combination with supercaps, first in a VW Bresa (January 2002) and later in a car with improved performance (October 2004). 

Switzerland - the Paul Scherrer Institute (PSI) established a strong collaboration with ETFIZ to improve bipolar plates for PEMs. The result of this collaboration was the liquid-cooled 1 kW PEM PowerPac, which was first demonstrated at the Hannover Fair in 2002. 

Production of 100 mm x 100 mm demonstrator PEC water-splitting tandem cells (WOj/TiOj Fe203Ai02), with scale-up program toward 300 mm x 300 mm devices - Switzerland and the UK. 

Measurements in an aquifer at the River Aare in Switzerland by Schwarzenbach et al. (1983) show a time lag of about 4 months between the concentration in the river and in a well situated about 13 m from the river. The corresponding amplitude ratio is about 0.8. In the same aquifer, the annual temperature variation shows a shift of 1 month from the river to the observation well. This demonstrates the more conservative (or less sorbing ) nature of water temperature versus PCE.

This concept was demonstrated at the Institute of Process Engineering and Cryogenics at ETH (Switzerland) during the last two years with the FilmCooled Hydrothermal Burner (FCHB). The FCHB operated at pressures of 25 MPa and temperatures up to 2000 K, cf. [1], Experiments and detailed analysis led to the basic design approach for SCWO reactors discussed herein which is based on wall boundary layer control and internal recirculation. 

Paracelsus (born Theophrastus Bombast von Hohenheim in Switzerland 1493) revolutionized the Alchemical Art and is considered to be one of the fathers of modern chemistry and pharmaceutical medicine. A respected physician and university lecturer, Paracelsus was also skilled in all of the arts of the Hermetic Philosophy. Paracelsus repeatedly demonstrated the power and effectiveness of alchemically prepared medicines.
