SOME twelve months ago Dr. Burr Fergusoni of the U-nited States Public Health Service, Southampton, spoke to me of the results he had obtained by injections of mercurv salicylate in the treatment of infective conditions, and I decided to try it in some suitable cases. The method consists in the intramuscular injection of a mixture of mercur-y salicylate in liquid paraffin (1 grain per cubic cen...

Metarril SP Organic is a product based on the fungus Metarhizium anisopliae, which was developed for controlling agricultural pests. The present study evaluated the effect of Metarril SP Organic plus 10% mineral oil, for controlling Rhipicephalus microplus under field conditions. Three groups were formed: Control group, which received no treatment; Oil control group, which was bathed only with ...

This paper discusses a new nuclear magnetic resonance (NMR) method that can provide wettability, saturation, and oil viscosity values in rocks partially saturated with oil and brine. The method takes advantage of two new technological advances in NMR well logging—the MRF* Magnetic Resonance Fluid Characterization Method and NMR “diffusion-editing” (DE) pulse sequences. We discuss the principles...

The plasmid profiles of 619 cultures of Bacillus anthracis which had been isolated and stored between 1954 and 1989 were analyzed using the Laboratory Response Network real-time PCR assay targeting a chromosomal marker and both virulence plasmids (pXO1 and pXO2). The cultures were stored at ambient temperature on tryptic soy agar slants overlaid with mineral oil. When data were stratified by de...

Toxic solutions applied at one end of a Nitella cell 6 cm. long may produce little or no visible change in the structure of the protoplasm at the place of application but if the opposite end is covered with water its protoplasm soon disintegrates. If the middle of the cell is covered with mineral oil this region remains normal in appearance for half an hour or more. The result is due to the mov...

This is an improved design of a palm oil extraction system with particular reference to Nigerian experience. Existing design conditions were carefully examined and necessary improvements made to enhance oil extraction efficiency. A detailed design of the oil extraction system was therefore done. The screw press design configurations, the effects of lagging, the casing of the press chamber, as w...
