    Notes: Induced polarization and resistivity model studies over thin dykes for varying resistivity contrasts, depth of burial, and dip angles show striking parallelism of the surface apparent resistivity contours with the boundary of the body. This effect may be utilized for the estimation of strike length of the body. Results show that intermediate values of the electrode spacing is satisfactory for detection under widely varying conditions of resistivity contrast and depth. The percentage frequency effect (P.F.E.) and the metal factor (M.F.) responses are found to be more sensitive to the variation in the depth of burial than the resistivity responses. Pseudosections for P.F.E. and M.F. are concentrated much closer to the body than the resistivity pseudo-sections.

    Notes: [Auszug] SIR Readers of your survey are likely to conclude that most of what is good and worthy of its name in Indian science is so because (1 ) a director or a chairman or perhaps a minister knows and means his/her business; (2) they or their organizations have or at least had good overseas connections ...

    Notes: Zusammenfassung Für die Probleme der langsamen zähen Flüssigkeitsbewegung, die durch die Bewegung von zwei sphärischen Begrenzungen verursacht warden, sind exakte Lösungen angegeben worden. Die Bewegung der Kugeln kann entweder eine Translation entlang oder eine Rotation um die Achse sein, welche senkrecht zur Verbindungslinie der Mittelpunkte geht. Die Kugeln können sich ausserhalb von einander in einer unbegrenzten Flüssigkeit befinden, oder die Flüssigkeit kann zwischen zwei exzentrischen Kugeln eingeschlossen sein. Die Theorie ist anwendbar für alle Werte der Radienverhältnisse (k) und der minimalen Distanz (ε) zwischen den Kugeln.

    Notes: Summary Laboratory induced polarization (IP) or overvoltage measurements over a spherical body at different depths is discussed. Some nomograms are also designed to calculate rapidly induced polarization parameters such as frequency effect, polarization factor and chargeability in the field or laboratory.
