Pop-up Langmuir probe diagnostic in the water cooled divertor of Wendelstein 7-X.

The design, development, and successful implementation of pop-up Langmuir probes installed in the water-cooled divertor of W7-X are described. The probes are controlled by drive coils (actuators) installed behind the divertor plates. These drive coils make use of the magnetic field in W7-X to move the probe tips into and out of the plasma.

A phenomenological and quantitative view on the degradation of positive electrodes from spent lithium-ion batteries in humid atmosphere.

The present study deals with the phenomenological observation of the corrosion of the positive electrode foil of lithium-ion batteries containing LiNiCoMnO (NMC) as cathode material. Due to the presence of moisture, localized water accumulation is formed on the NMC surface. The water absorbed by the electrolyte reacts with the NMC under Li/H exchange and the resulting pH increase leads to dissolution of the carrier foil and characteristic salt-like blooms on the NMC surface.

Administrative structures: Options for achieving success in perioperative medicine.

Without the appropriate administrative structure, even well-thought-out strategic plans or detailed process improvement initiatives will fail. Developing a strong foundation for governance and leadership is a critical element of any high-functioning organization, and it applies just as well in the perioperative setting. Yet, perioperative patient care teams and operating room (OR) management structures can be very complex, due to relationships both within the OR and between the OR and other departments.

A dynamic collimation and alignment system for the Helmholtz linear accelerator.

The upcoming commissioning of the superconducting (SC) continuous wave Helmholtz linear accelerators first of series cryomodule is going to demand precise alignment of the four internal SC cavities and two SC solenoids. For optimal results, a beam-based alignment method is used to reduce the misalignment of the whole cryomodule, as well as its individual components. A symmetric beam of low transverse emittance is required for this method, which is to be formed by a collimation system.

Investigating Host Preference of Root Endophytes of Three European Tree Species, with a Focus on Members of the - Species Complex (PAC).

Host preference of root endophytes of the three European tree species of Norway spruce (), common ash (), and sycamore maple () were investigated in two forest stands near Zurich, Switzerland. The focus was placed on members of the s.l.
