    Notes: The use of lime and phosphates in reclaiming heather moorland was investigated in two experiments.Large initial dressings of hme resulted in a rapid rise in pH. An initial dressing of 9 tons CaCO3/ac resulted in a more rapid rise to pH 6 than did 6 tons/ac and the soil was maintained above pH 6 for a longer period. Three annual dressings of 3 tons/ac gave a slower rise in pH and a longer period above pH 6. Split treatments, half before and half after the first ploughing, gave no long–term advantage where a programme of pioneer cropping was being followed.Basic slag and North African phosphate were as effective as superphosphate for root crops at low pH values. Basic slag was as effective as superphosphate for grassland establishment and gave a greater rise in soil phosphate. North African phosphate was virtually worthless as a source of phosphate for establishing grasses and clovers, and gave a negligible rise in soil phosphate.Given adequate supphes of lime and phosphate, frequent small apphcations of N over the first 2 or 3 years are vital to the success of a reclamation programme under the conditions described.

    Notes: Summary Intracellular electrode recording techniques were used to measure the responses of single visual cells in the locust to various intensities of monochromatic lights of wavelength 350 to 600 mμ. Response-energy curves, found for ten cells to be parallel at all wavelengths, were used to deduce the relative number of quanta required to evoke a constant response. The average response-energy curve from these ten cells was used in obtaining spectral sensitivity data for another ten short-lived cells, where only one response at each wavelength could be obtained. Spectral sensitivity curves for all twenty cells showed a peak in the blue-violet (maximum about 430 mμ) region of the spectrum. In addition, all cells showed some green sensitivity (maximum about 515 mμ) but in different cells this varied from 15% to 100% of the blue-violet maximum for the cell. The magnitude of the errors is discussed. The results are consistent with the hypothesis that two visual pigments which fit a Dartnall nomogram for rhodopsin are contributing, in various ratios, to the spectral sensitivity of every cell.

    Notes: [Auszug] Equation (1) is a particular case of a well known expansion theorem in quantum mechanics. The identity is exact only when the expansion is over the complete set of eigenfunctions of the Hamiltonian which describes vibrational motion in state G. This means that, in addition to the sum over discrete ...

    Description / Table of Contents: Sommaire Poursuivant un effort entrepris pour rassembler une certaine quantité de renseignments sur le caractéristiques mécanique de certaines parties du corps humains les chercheurs ont fait des mesures expérimentales sur les caracteristiques force—élongation des tendons de trois muscles du membre supérieur de l'homme. Ces résultats ont été comparés à ceux d'un rapport précédent concernant les tendons du muscle plantaire grêle. Un résultat intéressant, étonnant et très particulier était que des différences notables dans les élongations dûes à des charges furent observées. On constata en effet que les tendons qui sont apparement soumis à un effort total plus important en usage normal s'allongeaient davantage que ceux soumis à un effort moindre, lorsqu'on les observait sous des tensions identiques, c'est-à-dire que le module d'Young,E, pour les tendons des muscles fléchisseurs communs profond et superficiel des doigts fut trouvé notablement plus petit que la valeur deE pour les tendons du muscle extenseur commun des doigts et du muscle plantaire grêle.
    Abstract: Zusammenfassung Im Zusammenhang einer umfassenden Untersuchung, die zur Quantifizierung bestimmter Informationen über die mechanische Charakteristik von Teilen des menschlichen Körpers angestellt wurde, führten die Autoren experimentelle Messungen der Belastungs-Dehnungs-Charakteristik der Sehnen von drei Muskeln der menschlichen oberen Extremität durch. Die Ergebnisse wurden mit den früher gemachten angaben über den Musculus pläntäris verglichen. Ein interessantes und eigenartiges Ergebnis war die Beobachtung, daß signifikante Unterschiede in der Dehnung bei Belastung bestehen. Die Sehnen, die im Körper normalerweise wahrscheinlich unter stärkerer Belastung stehen, wurden bei gleicher Testbelastung stärker verlängert als solche, die bei normaler Körperarbeit anscheinend weniger belastet werden. Das bedeutet, daß der Youngsche ModulE der Sehnen des M. flexor digitorum profundis und superficialis beträchtlich kleiner als derjenige der Sehnen des M. extensor digitorum communis und M. plantaris ist.
    Notes: Abstract As a part of a continuing effort to quantify certain information about the mechanical characteristics of parts of the human body, the investigators have made experimental measurements of the stress-strain characteristics of the tendons of three muscles of the human upper extremity. These results have been compared to their previous report concerning the tendon of the M. plantaris. One interesting, provocative and peculiar result was that significant differences in strain under load were observed. Those tendons which are apparently subjected to greater total force in normal body use were found to elongate more than those which are apparently not heavily loaded in normal body use, when tested under equal stresses; that is to say, Young's Modulus,E, for the tendons of M. flexor digitorum profundus and superficialis was found to be significantly smaller thanE for tendons of M. extensor digitorum communis and M. plantaris.
