[Postgraduate training for psychiatric nurses: a bet for the future].

Today, our care environment in the psychiatric setting requires solutions to the issues of the shortage of nurses, premature departures from the profession, adaptation of skills to the complexity of care, integration of academic knowledge and replacement of senior experts. Nursing care is an essential pillar for the care of patients in the psychiatric settings and it is therefore essential to offer conditions to this personnel to guarantee the quality of care, the succession of nurses and professional autonomy for the implementation of good practices. The creation of a Certificate in advanced studies within the University of Lausanne offering a demanding training alternating face-to-face and e-learning is one of the responses provided by the Care Departments of Romandie.

Cross-linked poly(vinyl alcohol) as permanent hydrophilic column coating for capillary electrophoresis.

A fast method for the generation of permanent hydrophilic capillary coatings for capillary electrophoresis (CE) is presented. Such interior coating is effected by treating the surface to be coated with a solution of glutaraldehyde as cross-linking agent followed by a solution of poly(vinyl alcohol) (PVA), which results in an immobilization of the polymer on the capillary surface. Applied for capillary zone electrophoresis (CZE) such capillaries coated with cross-linked PVA exhibit excellent separation performance of adsorptive analytes like basic proteins due to the reduction of analyte-wall interactions.

Directed control of electroosmotic flow in nonaqueous electrolytes using poly(ethylene glycol) coated capillaries.

Poly(ethylene glycol) (PEG)-coated capillaries exhibit unique properties in nonaqueous electrolytes. Immobilized PEG interacts significantly with different cations present in nonaqueous electrolytes. This can induce a positive surface charge on PEG-coated capillaries and results in an adjustable anodic electroosmotic flow (EOF) in nonaqueous electrolytes whereas a reduced cathodic EOF is observed in aqueous electrolytes.

Influence of pH*-value of methanolic electrolytes on electroosmotic flow in hydrophilic coated capillaries.

The dependency of EOF on the H+-concentration and the related so called pH* value of methanolic electrolytes has been examined with poly(ethylene glycol) (PEG), poly(vinyl alcohol) (PVA) and uncoated capillaries. These results were compared with the pH dependency of EOF of these capillaries using aqueous buffers. In uncoated capillaries the dependency of EOF on the pH(*)-value is very similar for aqueous and methanolic electrolytes.
