In vitro pathogenicity tests demonstrated that Hirschmanniella caudacrena is pathogenic to Ceratophyllum demersum (coontail). Symptoms were chlorotic tissue, deformed stems, and, finally, death of the plant. Inoculum densities of 500 nematodes per 5-cm-long cutting in a test tube containing 50 ml of water resulted in death and decay of some of the cuttings within 8 weeks; 100 nematodes killed t...

A simple, rapid procedure for the presumptive identification of anaerobic bacteria has been evaluated. Two hundred and thirty-five clinical isolates were identified using gas-liquid chromatography and 3-ml volumes of a few selected test media. These test media were stored aerobically and incubated in GasPak anaerobic jars. The average incubation time was 39 h. This procedure, when compared to t...

The bioefficacy of a commercial formulation of temephos, Creek against Aedes aegypti larvae was studied in the laboratory. Earthen jars were filled with 10 L tap water each. One g of temephos (Creek) sand granule formulation was added into each earthen jar as recommended by the manufacturer. The final test concentration of Creek was 1 mg a.i./L. One earthen jar was filled with 10 L tap water an...

' Received Sept. 27, 1962. ing 125 mm being miiade up with either argon or ethylene. The followiing gas mixtures were used: air, 10 % 02 + 90% A, 7.5% O., + 92.5 % A, 5% 02 + 95% A. In other experimlenits the partial pressure of ethylene in the jars was varied from 0 to 253 nim Hg, while the O. level was maintained at 5 % and total pressure adjusted to 760 mim with argon. For comparative purpos...

This paper contains data and supporting information of and complementary to the research article entitled "Effect of jar shape on high-energy planetary ball milling efficiency: simulations and experiments" (Broseghini et al.,) [1]. Calcium fluoride (CaF2) was ground using two jars of different shape (cylindrical and half-moon) installed on a planetary ball-mill, exploring different operating co...
