Chemical analyses have been made of the lipids and mucopolysaccharides isolated from fatty streaks, plaques, atheromas and intimal tissue (after removal of all the lesions) of human aortas both undiseased and at different stages of atherosclerosis.

The friction properties and the well reproducible endurance limits of MoS2-lubricant films, prepared from the dry powder, were studied on rigs. Special consideration was given to: (i) automation of the rubbing-in process, (ii) the control of temperature and atmosphere, (iii) photographic recording of the friction surface. The influence of...

A new and rapid method for determining cysteic acid in a mixture of amino acids has been developed. For the separation, use is made of chemically modified paper containing quaternary ammonium groups. Quantitative determination can be done on the paper densitometrically as well as spectrophotometrically (after elution). The densitometric...

For a cylindrical woodwind and in particular for a clarinet, methods are derived to calculate location and diameier of the holes. In a simple way the calculations are carried out for each hole separately, and independently of the other holes. Corrections are introduced for the influence on the resonance frequency of the overblowing hole and of...

The rate of decay of auditory sensation was investigated by measuring the minimum silent interval that must be introduced between two noise pulses to be perceived. The value of this critical time Δt was determined for difierent intensity levels of both the first and the second pulse. It is shown that in this case the sensation level of the...

A quantitative analysis of mixtures of polyphenyls can be achieved by Chromatographic separation on thin-layers of alumina G using n-heptane as the mobile phase, extraction of the separated spots by n-heptane or methylene chloride and spectrophotometric determination of the extracted compounds. © 1964 Springer-Verlag.

A new method for measuring cochlear summation is introduced. This method is an analog of the method earlier applied for measuring retinal summation. The probability of hearing pulses of two small noise bands presented simultaneously is measured as a function ot the frequency difference between these noise bands. Within the experimental error,...
