Notizen: [Auszug] Comparison of Tables 1 and 2 shows the enormous increase in microbial numbers due to the planting and growth of trees. Also it will be seen from Table 2 that the highest numbers of micro-organisms are found in the top few inches. Here, too, the formation of a thin zone of humification is evidence ...

Notizen: [Auszug] In December last, Dr. E. W. Hullett, director of the Wheat Research Institute, New Zealand, was in England, and directed the attention of one of us (T. M.) to this paper by Vuataz and the light it threw on his own earlier work. As a result, following a discussion with Dr. Hullett and Dr. E. ...

Notizen: [Auszug] In the following investigations, healthy and virus-infected tubers of the same degree of maturity were used. Unless otherwise stated, the tubers were grown at the Dickson Experiment Station, A.C.T. Two short metal pins1 at the end of a glass tube were inserted into a tuber, in most cases at the ...

Notizen: [Auszug] On examining the literature, we noticed records to the effect that l-chloro-3-ethoxypropene-l had been isolated from the products of reaction of 3,3-dichloro-propene-1 with sodium ethoxide3, and that the total process had been shown to have approximate second-order kinetics4'5. Certainly, the fact ...

Notizen: [Auszug] Recently, publication of improved methods of preparation of 3 : 7-dihydroxy-12-keto cholanic acid and its derivatives (see, for example, Fieser et al.3), together with the Huang-Minion4 method of reduction of ketones, have led us to re-investigate the production of chenodeoxycholic acid by this ...

Notizen: [Auszug] Maxwell?s3 value Tc = 3.662K. for an enriched sample with M = 123.1 lies well on a graph of these results, and so too does the value Tc = 3.726K. for natural tin4 (M = 118.7). A log-log plot shows that our results are consistent with the relation Tc a 1/M1/2, but until the atomic weights have been ...

Notizen: [Auszug] A re-examination of the reaction in a spherical 2-litre 'Pyrex' vessel using peroxide pressures of a few millimetres of mercury has, in the main, confirmed the results obtained by Harris and Egerton. Our velocity constants, derived from initial rates, were however about 25 per cent greater than ...

Notizen: [Auszug] Garner and Gomm1, Cosslett and Garner2 and Hadman, Thompson and Hinshelwood3 found water vapour to have no effect on the lower explosion limit. In accordance with this, we find that water vapour has no effect on the lower glow limit. Hadman et al.5 also concluded that water vapour had no effect on ...

Notizen: [Auszug] In view of the fact that the cell-wall preparations obtained might have been chemically or mechanically degraded from their natural state in the whole organisms, conditions of rupture were sought which would minimize such degradative changes. A sensitive strain of Staphylococcus aureus was either ...

By the use of transformations which do not change any bond of the asymmetric carbon atom, it has been shown, for ...
