Copper Soap

The use of a mixture of copper soap, 5 or 10 per cent, with 1 per cent mineral oil, dissolved in petrol or benzol, increases the life of silk plankton nets by about four or five hundred per cent, and roughly doubles that of a hemp net for a single treatment. The beneficial effects last far longer than does the green colour. Re-treatment at suitable intervals is recommended.The use of 5 or 10 per cent of resin * with an equal percentage of the soap improves its adherence to the fabric, as does also the addition of tar or anti-fouling paint. For silk nets, to avoid clogging, only one-half per cent of resin should be used with 5 per cent of soap.A liquid soap mixture, which may be used with paraffin oil, can be obtained by adding one pound of resin to one pound of melted copper soap, and then dissolving in one and a half pounds of carbon tetrachloride. When wanted, this is used to make up a paraffin oil soap solution of the desired concentration, but adherence is less than with petrol.

Abstract A collaborative study has been completed on a new method for light filth in ground coffee. The sample is defatted with chloroform, dried, and boiled in water; isopropanol is added and the sample is boiled again. Light filth is trapped off with mineral oil from a hot solution. The method yields better recoveries of insect fragments and rodent hairs than the official method. Other advantages are less analytical time, cleaner filter papers, and elimination of the use of carbon tetrachloride. It is recommended that the method be adopted as official first action to replace 40.007(b) for the isolation of light filth from ground coffee and that the hydrogen peroxide bleaching technique described earlier be adopted as a procedure to replace the sodium hypochlorite technique described in 40.006.

Acute lipoid pneumonia (LP) in children is a rare disorder caused by the aspiration of oil-based substances and is difficult to diagnose due to non-specific clinical symptoms and radiological findings. We report the case of a 5-month-old male infant with acute LP caused by accidental aspiration of a large amount of mineral oil. We present the imaging findings in the computed tomography scans performed during his hospitalization and focus on the residual abnormalities seen on a scan performed 7-years after the incident. This, to the best of our knowledge, is the longest follow-up report of an acute exogenous LP patient and the only case that demonstrates non-resolving abnormalities in a pediatric patient after a single acute episode of mineral oil aspiration.

Measurement Deviation

Density is a measure of the mass of volume unity. How to measure density in general by measuring the weight and dividing it by the volume of liquid, so in this way the measurement is not. Measurement of the density of the liquid based on the ultrasonic velocity becomes an alternative so that the measurement can be done directly, accurately, practically, and easily.Ultrasonic velocity becomes the variable to determine the density of the liquid. Time synchronization begins when the ultrasonic transmitter emits ultrasonic and is terminated when the receiver receives ultrasonic. The discrete ultrasonic wave transmission method is performed when the ultrasonic receiver receives transmittance from the ultrasonic transmitter then the 40KHz signal pulse is stopped and ultrasonic transmission is repeated up to 10 times the measurement data.From this study obtained some conclusions. Ultrasonic velocity is influenced by the viscosity of the liquid, ultrasonic velocity through 1394m / s aquades, ultrasonic  velocity through cooking oil 1387m / s, ultrasonic velocity through liquid soap 1175m / s, ultrasonic velocity through liquid soap solution 40% 1317m / s , Ultrasonic velocity through liquid soap solution 70% 1257m / s, velocity measurement deviation of 0.43% and 0.01% density calculation type.

(1) Examination of the inmates of Government reformatories in the Highlands of Kenya showed a high incidence (57·9 per cent.) of very light infestations with hookworm, and an incidence of approximately 50 per cent, of Taenia infestations. Many of the latter are not detected by the usual microscopic examination.(2) Treatment with carbon tetrachloride in doses of from 1½c.c. for children to 4 c.c. as the standard adult dose gave approximately 76·1 per cent, cures for hookworm, and in the case of boys with fairly light infestations with T. saginata an efficacy of approximately 97 per cent. In the case of 72 boys very heavily infested with Taenia 58 per cent. cures were effected by a single treatment with carbon tetrachloride and oil of chenopodium.(3) A combination of carbon tetrachloride and oil of chenopodium appears to be a safe and efficacious anthelminthic for the common worm infestations of man in Kenya.(4) Growing natives lightly infested with hookworm appeared to grow and increase in weight at a normal rate, and did not improve in physical condition after treatment.(5) Boys in the same institution infested with Taenia progressed at a subnormal rate, but increased to a figure above normal after treatment, the increase appearing to be mathematically significant in spite of the small number of samples analysed.

Studies are reported on the blood levels of carbon tetrachloride following administration of 8 ml of the drug to sheep by ruminal, abomasal, and intramuscular routes. Absorption was most rapid with ruminal administration, slowest with intramuscular, and intermediate with abomasal administration. The drug could be detected in expired air within 5 min of administration. Peak levels in the blood of c. 16 to 20 pg per ml were reached, with ruminal and abomasal administration, at c. 15-30 min and 60-120 min respectively. With intramuscular administration the peak of c. 10 �g/ml was reached at about 4 hr. Undetectable levels, less than 5 pg/ml, were reached at c. P 5 hr with ruminal administration, 6-7 hr with abomasal administration, and c. 10 hr with intramuscular injection. Carbon tetrachloride could be detected in the expired air up to 40-60 hr after administration, depending on the route. The blood curves were not appreciably different whether the drug was administered in the pure state or in paraffin oil. Fasting for 48 hr also had no appreciable effect. Fat sheep showed lower levels and a longer period of excretion than animals in poorer condition, presumably owing to partitioning into adipose tissues.
