Vonk, J.W. (author), Kaars Sijpesteijn, A. (author), Organisch chemisch instituut TNO (author)A study was made of the fate in plants of ethylenebisdithiocarbamate fungicides and their decomposition products. Nabam (disodium ethylenebisdithiocarbamate) is known to decompose rapidly in aqueous environment, mainly to ethylenethiourea and ethylenethiuram monosulphide. Only ethylenethiourea was taken up by the roots and leaves of cucumber...article 1970

Otto, P.P.H.L. (author), Besemer, A.C. (author), Wientjens, W.H.J.M. (author), Centraal laboratorium TNO (author)The synthesis of β‐sitosterol‐3‐14C, specific activity 5 mCi/mM, radiochemical purity ≥98 %, is described. Starting from stigmasterol, the complete synthesis consists of eleven reaction steps. It is based on methods described in the literature. For some of the steps, a considerable improvement in yield has been achieved. The actual labelling...article 1970

Mackor, A. (author), de Boer, T.J. (author), Organisch Chemisch Instituut TNO (author)The photochemical nitrosation with t‐butyl nitrite of some branched‐chain hydrocarbons, containing tertiary hydrogen atoms leads to the formation of monomeric nitroso compounds in yields up to 78%, when a special Soxhlet technique is employed. The use of wavelengths around 400 nm is essential for this reaction.article 1970

Ong, P.H. (author), Centraal Laboratorium TNO (author)The dielectric properties of the composite system polyurethane-sodium chloride have been measured at frequencies between 10<sup>-4</sup> Hz and 3 · 10<sup>5</sup> Hz in the temperature range from -150 °C up to +90 dgC. Three dielectric loss mechanisms have been found; they are indicated by α<sub>1</sub>, α<sub>2</sub> and β. The activation...article 1970

Maarse, H. (author), Kepner, R.E. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)The compositions of the volatile terpenes in Douglas fir new tip growth and in year old needles were investigated over a growing season using a simultaneous steam distillation-extraction method and direct vapor analyses. The results demonstrate the almost complete absence of acyclic oxygenated monoterpenes and cis-ocimene in the new tip growth...article 1970
