Received for publication 12 July 1968. ashed in a muffle furnace at 600'C for at least three hours. Of the acid ammonium sulphate, 10 ml, and 30 ml of water are added to the ashed sample, and after warming to dissolve soluble material the contents are decanted with washing into a 50 ml centrifuge tube, the BaSO4 being washed into the tube as far as possible. The tube is centrifuged for 5 min, t...

conclusions it is suggested that the training of nonpharmacological methods to improve sleep quality such as reflexology and foot bath be included in the elderly health programs. in addition, it is recommended that the impact of these interventions on subjective sleep quality using polysomnographic recordings be explored in future research. background sleep disorders are common mental disorders...

In this research, we are analysing the behaviour of the wastes coconut shells of african palm (Elaeis guineensis) when dealing with different gas mixtures and its influence on the development of lattice porous internal and its formation as foam. The study shows that samples worked with water vapour mixtures developed the highest percentage of carbon foam as foams. The greatest expansion of the ...

WHEN the collection of faeces during a metabolic experiment extends over a considerable period of time, difficulties arise in the determination of the total nitrogen and sulphur contents. Sampling of the wet composite specimen is generally unsatisfactory and ordinary methods of drying on a steam-bath result in a considerable loss of both nitrogen (as ammonia) and sulphur (mainly as sulphide). I...
