Resting barley (Hordeum vulgare L.) grains contain acid-proteinase activity. The corresponding enzyme was purified from grain extracts by affinity chromatography on a pepstatin-Sepharose column. The pH optimum of the affinity-purified enzyme was between 3.5 and 3.9 as measured by hemoglobin hydrolysis and the enzymatic activity was completely inhibited by pepstatin a specific inhibitor of aspartic
A pilot study has been conducted to find out if and how the building process influences the indoor air or the perception of the indoor air. As the first part of this investigation, a media study of what are considered to be healthy and unhealthy buildings was performed. From this media study two buildings were chosen and their building processes were examined more closely. This was carried out as
This Licentiate dissertation deals with windows and solar shading devices and how they could be designed and used to save energy for heating and cooling in buildings. Parametric studies using the dynamic energy simulation software ParaSol v 2.0 were performed for different windows and solar shading devices. One study showed that both the cooling load and the annual cooling demand could decreased
