[The nurse's work in psychiatric emergencies].

Emergency psychiatric situations represent at least 10% of all admissions in general emergency departments in hospitals. The CPOA, the psychiatric orientation and consultation centre, is one of the main units in Paris which deals with crises. The specificities of its practice make it a benchmark centre both in terms of its clinical expertise as well as its care network.

[Taking care of a newborn suffering from dysmorphism].

Taking care of a newborn suffering from dysmorphism tests nurses' professional ethics. Lack of awareness of the pathology and professional fragility can fuel the healthcare worker's moral conflict. A study carried out in neonatology shows that the phantasmagoric imaginations of the healthcare worker heighten the unease while training and service culture contributes to self understanding and the easing of tensions.

Applications of NIR spectroscopy to monitoring and analyzing the solid state during industrial crystallization processes.

Fiber-optic near infrared (NIR) spectroscopy was used to investigate several key features of the polymorphic transitions observed during the crystallization and the filtration of SaC, an Active Pharmaceutical Ingredient (API) produced by Sanofi-Synthelabo. Using few samples, the spectroscopic data were calibrated to provide measurements of the polymorphic composition of the solid product which is likely to appear in two crystalline forms or in the amorphous state. Both qualitative and quantitative methods were successfully evaluated to characterize the API.
