    Notes: [Auszug] ALTHOUGH efforts have frequently been made to develop a gas analyser depending on the variation of the velocity of sound with the nature of the gas, no practical instrument was produced until quite recently. The successful development of this gas analyser is due to the efforts of, among others, J. ...

    Notes: [Auszug] To extend the field of usefulness of gas chromatography, the need for a more uniform and more sensitive means of detecting each component as it emerges from the column has become apparent, and the infra-red gas analyser appears to meet these requirements in many cases. For infra-red absorbing ...

    Notes: Summary 1. The urine of the octopus,Octopus hongkongensis (Hoyle), has been subjected to a qualitative analysis for 38 different elements. 2. Only 12 ions, namely, ammonium, calcium, magnesium, potassium, sodium, zinc, arsenate, bromide, chloride, fluoride, phosphate, and sulfate, were present in detectable amounts. 3. Quantitative measurements of these 12 ions were attempted, and the results were compared with sea water composition.

    Notes: [Auszug] From the general form of the grating equation d(sin 0i + sin 62) = n\ (1) (2) where d is the grating spacing, 0i the angle of incidence, 02 the angle of diffraction, X the wave-length and n the order of the spectrum, it is obvious that for a given geometrical configuration X in the first order ...

    Notes: [Auszug] A convenient band shape for the present purpose is A = - 4. max. (1 + cos x) where x has the extreme values?-TT and TC, A is the absorbance and ccOCv? v0(vis the frequency and v0 corresponds to the band maximum). On integration with addition of the appropriate constant, Adx = i max. (a? + sin x ...

    Notes: [Auszug] DURING the past few years both difference (sometimes called differential)1 and derivative spectra2 have been employed to bring out details of the spectra of minor components in the presence of a strong absorption background due to basic material. In the first method, the background absorption is ...

    Notes: Zusammenfassung Es wird ein Verfahren erarbeitet und geprüft, das es gestattet, routinemäßig auch bei den meist geringen mittleren Gewichtsdifferenzen intramuskulär wachsender Mäusetumoren zu signifikanten Untersuchungsergebnissen zu gelangen. Das Verfahren wurde als brauchbar befunden, sowohl für die intramuskulär wachsende Form des Ehrlich-Ascites-Carcinoms als auch für drei weitere, von uns6 in der Ascitesform weitergezüchtete Spontantumoren der weißen Maus.
