    Notes: [Auszug] IN your account of the death of Mr. Fox Talbot (NATURE, vol. xvi. p. 464), you state that he first entertained the idea of the art of what is now called photography in 1833, and that it was not till 1839 that he and Daguerre first made known the principles of photography under the name, I ...

    Notes: [Auszug] Although McCrea recognized the effect of compressibility, he did not calculate its effect on the density. We now estimate this effect using the data given in Kaula's textbook3 and in references cited therein, in particular Ring-wood4. Table 1 compares the actual density given by McCrea with the ...

    Notes: [Auszug] The chief problems of obtaining reliable information about tin in seawater are the lack of sensitive, specific analytical procedures, and the difficulty of excluding contamination from apparatus, reagents and the environment, particularly during the initial stages of concentration and separation. ...

    Notes: [Auszug] We propose a scheme for selecting specific oxygen sites on the basis of a theory which attempts to consider the complex interactions between a hydroxyl group and its neighbouring atoms. We shall consider hydroxyl groups formed by the attachment of a proton to an oxygen atom of the continuous ...

    Notes: [Auszug] In our investigations, the source of ChA used was a 100,0000g supernatant of homogenate of rat cerebral cortex diluted 1: 30 with distilled water. ChA activity was assayed by a modification of the radioactive method of McCaman and Hunt3 and the electrophoretic method described here. All cysteine ...

    Notes: [Auszug] Orf virus infection of sheep is well known as contagious pustular dermatitis (CPD). None of our seven patients had been in contact with sheep, but all had milked cows within three weeks of onset of their lesions. Orf infection of cattle has not been reported, so these human infections would have ...

Although many cephalosporins are resistant to hydrolysis by [3-lactamases from Gram-positive ...

    Notes: [Auszug] Raw silk was obtained from Gerli and Co., Inc., Park Ave., New York, and ground in a Wiley mill. For dry weight determinations, aliquots were dried in a vacuum drying apparatus over boiling toluene with P2O5 as a desiccant. The ground silk was hydrolysed with twenty times its weight of 4 N HC1 in ...
