    Abstract: The ductile deformation in the paragneissic bed of Mvog-Betsi in the north-eastern part of Yaounde (Cameroon) appears to be intensive and may be traduced by a high shear rate (more than 10%). Some marker subjects that may quantify this strain are observed. Those are elliptical quartz and feldspar, and folds. The study of elliptical markers shows th... Show More

    Abstract: Surface and underground extraction of coal has degraded many landscapes throughout the Appalachian region of the United States. The deleterious effects on steam biota of untreated acidic drainages high in heavy metals from active and abandoned sites have been well-documented. Mitigation strategies frequently include the addition of strong neutraliz... Show More

    Abstract: The toxicity of essential oils and wood vinegar was tested on stored-product insects that infest rice. The essential oils from 5 plants, lemon grass Cymbopogon citratus Stapf, citronella grass Cymbopogon nardus Linn, pomelo peel Citrus maxima (Burm) Merr, eucalyptus Eucalyptus globulus Labill, and kaffir lime peel Citrus hystrix, were extracted by ...
