Brief studies of microearthquakes in four separate parts of eastern Afghanistan reveal a high level of seismicity over a broad area. In general, the activity is not concentrated on well-defined faults, nor does it define new faults, but seismicity on or close to the Chainart and Sarubi faults attests to their activity. First motions of P waves are consistent with left- and right-lateral strike-slip motion, respectively, on these two faults.

Information available on the present status of genetic diseases in India is relatively meagre, considering the number and varieties of its populations. Data, based mainly on those from uurban referral units, suggest that the incidence is fairly high with the preponderance of certain defects in particular areas and subpopulations.

Vinoba Bhave's demand for banning cow slaughter in Kerala & West Bental and his fast for gaining its acceptance raise three sets of issues; (a) the constitutional and legal basis of the demand, (b) its economic rationale and (c) the political implications and possible consequences. This note examines these issues.

The insecticide endosulfan, has been widely used for the control of crop pests in the field of agriculture. Although no mutagenic, teratogenic or carcinogenicity information is available on this insecticide, there are several reports concerning its toxicity after oral as well as from repeated administration in mice, rats and rabbits.

A weed which was carried into India from the United States has spread within a decade across a thousand miles of the country from Bangalore in the south to Kashmir in the north. This prolific plant, Parthenium hysterophorus, has brought with it a near epidemic of contact dermatitis. The outbreak is so serious that the Indian Department of Science and Technology held a meeting to see what can be done to eradicate this unwelcome intruder.

The distribution of carbonate on the floor of the Pacific has been remapped on the basis of 1313 points from 80 references stored in the World Ocean Sediment Data Bank of Scripps Institution of Oceanography. Percent distribution maps and carbonate versus depth diagrams generally agree with previously published information and reflect the major controlling factors of carbonate sedimentation (depth, hydrography, fertility, and sedimentary processes). While carbonate distributions are of limited use in attempting to construct dissolution profiles, major trends are identifiable.

Methods of digestion of fish samples for mercury determination by flameless atomic absorption spectrophotometry have been investigated. Digestion in Teflon bombs, Kjeldahl flasks, or borosilicate test tubes gives comparable precisions and mercury recoveries. Because of their cost and effect in limiting productivity, Teflon bombs were considered unnecessary for analysis of fish samples. Experiments with cooked and uncooked fish samples have confirmed that no appreciable loss of mercury occurs during baking 30 min at 170 degrees C.

From Kashmir to Burma, where tigers once lived amid lush forests, a vast tract of land has been laid bare by the timber industry. In its wake have come landslides, drought and yet further poverty. The only hope for the hill people is a Ghandian like movement which villagers have adopted to thwart developers.
