Journal ArticleDOI
TL;DR: In this paper, the toxicity of copper and zinc to the green mussel, Mytilus viridis, was evaluated by short-term bioassays using Probit analysis for calculating 48 h median tolerance limits, 95% fiducial limits and slope functions.

TL;DR: In this paper, the authors gave an estimation of fluoride in the Northern Indian Ocean and gave an average concentration of 1.31 ± 0.01 mg/l and a F/Cl ratio of (6.84 ± 1.01) · 10−5.

TL;DR: In this article, maps showing the distribution of depth, acceleration potential, salinity and oxyty were prepared for the northeast monsoon for the four potential thermosteric anomaly surfaces: 160, 120, 80 and 60 cl/t.
Abstract: Using the data collected during the International Indian Ocean Expedition, maps showing the distribution of depth, acceleration potential, salinity and oxyty were prepared for the northeast monsoon for the four potential thermosteric anomaly surfaces: 160, 120, 80 and 60 cl/t. Zonal components of current aong 84°E were computed from the geopotential dynamic heights. From such an analysis, it became clear that low-salinity water from the Pacific intrudes into the western Indian Ocean through the Banda and Timor seas in the upper layers above 100 cl/t surface, while the North Indian Ocean Water penetrates towards the Eastern Archipelago below 100 cl/t surface. The South Equatorial Countercurrent and the Tropical Countercurrent are well depicted on the vertical section of zonal components as well as on the distribution of acceleration potential.

TL;DR: A new calanoid copepod, Archidiaptomus aroorus n.
Abstract: A new calanoid copepod, Archidiaptomus aroorus n. g., n. sp., is being described from India. Though placed in the family Pseudodiaptomidae, the new genus shares many features with the family Diaptomidae. The remarkable intermediate position of Archidiaptomus between these two families is being discussed in morphological as well as in historical sense.

Journal ArticleDOI
TL;DR: To improve the efficiency and reduce the initial cost of solar still a modified unit was designed and tried The trials showed that besides the top cover, the side walls when fabricated from glass help in increasing its fresh water yield by about fifty per cent Further a unit with glass sheet costs just half than that of RCC materials.

TL;DR: In this article, a program for calculating grain size data on the DCM desk calculators (MOSCAL-1080 PS and MICROSYSTEM 1101) is described.
Abstract: The programme for computation of grain size data on the DCM desk calculators (MOSCAL-1080 PS and MICROSYSTEM 1101) is described. In these programmes the weight percentages or sample weights are used to compute standard statistical parameters by the method of moments. Details are given on data preparation and operation of the programme. A flow chart and the programme are given along with a test problem.
