Gezondheidsorganisatie TNO Radiobiologisch instituut TNO (author), Broerse, J.J. (author), Barendsen, G.W. (author)At interfaces of tissues of different composition in intact organisms local perturbations of charged particle equilibrium occur, which may be different for irradiations with fast neutrons and electromagnetic radiation. The variations in absorbed dose at the interface of bone and soft tissue have been investigated with a cell culture system. For...conference paper 1967

Gezondheidsorganisatie TNO Radiobiologisch instituut TNO (author), Barendsen, G.W. (author)Relations between the relative biological effectiveness and the linear energy transfer of heavy charged particles for impairment of the reproductive capacity of cultured mammalian cells are discussed, which have been measured in experiments, whereby the LET was varied either by variation of the velocity of the ionizing particles or by using...conference paper 1967

Gezondheidsorganisatie TNO Radiobiologisch Instituut TNO (author), Barendsen, G.W. (author)In this contribution several features will be discussed of relations between biological effects produced by ionizing radiations and the spatial distributions of energy deposition of these radiations. Effects produced by high-LET radiations are generally found to be less dependent on dose-rate, dose-fractionation and on the influence of cellular...conference paper 1967

Centraal laboratorium TNO (author), van Duin, P.J. (author), Kruissink, C.A. (author)It has been shown by impedance measurements that over a large range of potentials the current at the oxygen electrode of hydrogen-oxygen ion exchange membrane fuel cells is controlled by a charge tra11sfer reaction. The frequency range used covered six decades. The influence of the hydrogen ion concentration on the rate of the electrode...conference paper 1967

Leenhouts, A.J. (author)Ofschoon het publiek gebruik van ruimtevaartuigen op zijn minst nog in het verre verschiet ligt is het wel interessant om zich eens af te vragen wat de kosten daarvan zouden zijn. Zonder enige pretentie van nauwkeurigheid mag het tarief voor het brengen van betalende lading in een baan om de aarde thans op ongeveer 150 gulden per gram gesteld...conference paper 1968

Physisch Laboratorium RVO-TNO (author), van Schooneveld, C. (author)The paper reviews a number of designs of cross-correlation receivers for the detection of active underwater transmissions. Particular attention is given to the various structures of phase insensitive receivers, and to the problems concerned with clipping of the input signal and the reference function.conference paper 1968

Centraal laboratorium TNO (author), Ritter, F.J. (author), Prins-van der Meulen, P.Y.F. (author), van der Marel, T. (author)Using starch gel electrophoresis according to Smithies, desalted crude cellulase from Myrothecium verrucqria was separated into at least 12 protein zones. These were tested on their activity towards p-nitrophenyl-beta-D-glucoside, sodium carboxymethylcellulose and alpha-cellulose. They were all hydrolytically active. When the separate proteins...conference paper 1968
