? Mertens, T.E., Fernando, M.A., Marshall, T.F., Kirkwood, B.R., Cairncross, S. and Radalowicz, A. (1990), Determinants of water quality, availability and use in Kurunegala, Sri Lanka. Tropical Medicine and Parasitology, 41 (1), 89-97.

Abstract: Between January 1987 and February, (1988), 4590 homes of children under five years of age were visited in three areas of Kurunegala district, Sri Lanka and data were collected on water related practices. 60% of the population used protected wells, 30% used unprotected sources and 10% used handpumps on boreholes or piped supplies. 90% of households had a source less than 1 km away. Mean water consumption was above 25 litres per capita per day and did not correlate with the distance to source. Samples of drinking water were collected and faecal coliform levels were determined in samples of stored water from 3092 households and in samples from the water sources used by 1043 of these households. The absence or presence of organisms in each sample, and the geometric mean count in samples with organisms were used as indices of contamination. Both indices changed with season and varied between areas and between types of water source. The proportion of positive source samples was uniformly high with the exception of piped supplies and handpumps. The mean count was highest for unprotected sources. There was no evidence that ground water contamination occurred in boreholes. With stored samples, boiling appeared to reduce contamination markedly. The proportion of positive stored water samples was also lower with the use of different vessels for collection and storage, with storage inside the house, and with use of a storage container other than an earthenware pot. Because surface water pollution appears to be important it is proposed that headwalls and drainage aprons be built around unprotected sources. Faecal contamination at the source may have more public health significance than contamination of stored water. In this respect public hygiene may play an important role in reducing water pollution at handpumps or protected wells.

? Abate, T. (1991), Seed dressing insecticides for bean fly [Ophiomyia-phaseoli (Tryon) (diptera, agromyzidae)] control in ethiopia. Tropical Pest Management, 37 (4), 334-337.

Abstract: Six seed dressing insecticides were tested for efficacy against Ophiomyia phaseoli (BF) in 1987 and 1988 at two locations in south-central Ethiopia. Endosulfan and aldrin, at 5 g a.i./kg of seeds, were the least phytotoxic and the most effective. The rest gave variable results; BF control with some insecticides (e.g. furathiocarb) was comparable, but they showed varying degrees of phytotoxicity. The maximum seed yield loss was 36.5%. The results suggest that aldrin be replaced with endosulfan, which is less persistent.

Abstract: The kinetics of the sorption of Cd2+ and Cr3+ from aqueous solutions by mercaptoacetic acid modified and unmodified oil palm fruit fibre adsorbents were investigated. The results indicate that sorption equilibrium was reached within 60 min for both metals. Also, the removal efficiency of the three adsorbents was observed to increase for both metals with stronger treatments with mercaptoacetic acid. This may be attributed to the influence of the thiolation of the adsorbents. Furthermore, Cr3+ had higher removal percentages than Cd2+ for all the adsorbents. The sorption mechanism based on the intraparticle diffusion model shows that Cd2+ sorption is better described than Cr3+. The intraparticle diffusion rate constants, Kid, for Cd2+ are 62.04 min-1 (untreated), 67.01 min-1 (treated with 0.5 mol/L mercaptoacetic acid), and 71.43 min-1 (treated with 1.0 mol/L mercaptocacetic acid) while those for Cr3+ are 63.41 min-1 (untreated), 65.79 min-1 (0.5 mol/L acid treated), and 66.25 min-1 (1.0 mol/L acid treated). © 2007 Tsinghua University Press.

Abstract: Science policy decisions entrusted the Hungarian Academy of Sciences with the modernization of the information supply of fundamental research. This task might be successfully solved by using machine readable data base. This article was prepared in the Library of the Hungarian Academy of Sciences in the course of a preparatory work for modernization of the information programme of the Academy. Its intention is to clarify the availability of the source periodicals of the Science Citation Index and the Social Sciences Citation Index.
