A Study of Physicochemical Properties of Stockpile and Ponded Coal Ash.

The article describes chemical and also selected physical properties of ponded high temperature fly ash (FA) and bottom ash (BA) from a Mělník lignite power plant located in the Czech Republic. The research was carried out on samples obtained from drills with a depth of up to 54 m and the age of the samples retrieved from the lowest layers of the stockpile dating back to 1960. At the same time, a comparison was made with fresh fly ash and fresh bottom ash obtained from the identical power plant.

The quality of life of patients suffering from schizophrenia--a comparison with healthy controls.

Background: In the past, the first goal of schizophrenia treatment was to reduce psychotic symptoms, mainly positive symptoms. Recently, as a result of an emphasis on patient needs, the concept of quality of life (QoL) has been brought into the treatment. The goal has therefore changed from the alleviation of symptoms to improvement of the patient's satisfaction with social activities.
