    Notes: [Auszug] The source of this acid has been the mixed fatty acids from the saponification of rape-oil which, in addition to about 50 per cent erucic acid, contain quantities of oleic acid and smaller amounts of linoleic and C16-C24 even-numbered saturated acids. Schlenk and Holman1 have prepared urea ...

    Notes: [Auszug] This crystal, however, provides only a special case, in that no phase differences exist between the scattered waves. Buerger2 has solved the problem of introducing phase differences by the use of mica plates, tilted to produce the required retardation. Marcasite, FeS2, the crystal to which he has ...

    Notes: [Auszug] IN some recent publications1"5, we have advocated the use of optical diffraction methods in crystal-structure determination, and have shown how they could have been applied to some known structures. The test of the methods, however, lies in their application to new problems, and this present ...

    Notes: [Auszug] The methods suggested by Bragg were two-fold : first, the summation of Fourier series by optical interference1, and, secondly, the use of optically derived Fourier transforms2. The first suggestion has been developed with some success by Buerger3,4, and we are also hoping to make use of it on ...

    Notes: [Auszug] RECENT studies on the growth of potato plants in Australia by Bald and Hutton1 indicate that all varieties of potatoes grown under identical conditions are likely to show similar growth-rates during the early stages of vegetative development. Earlier, Bald2 had propounded a general plan of growth ...

    Notes: [Auszug] Dilution plates (1 : 500,000) were made from various soils in an agar medium containing soil-extract (25 per cent), peptone (005 per cent) and yeast-extract (0-05 per cent). Many of the cultures obtained from colonies on these plates would not grow initially in a casein-salts-vitamins medium, but a ...

    Notes: [Auszug] WHILE there is a considerable fund of knowledge on the physical and chemical factors affecting the loss of available phosphate, or ‘phosphate fixation’, in soils, there is very little published work on the part played by soil micro-organisms in the process. Phosphorus can either be utilized by ...
