UNLABELLED A method is described for growth of a Lactobacillus plantarum starter culture in jars of commercially available pasteurized fresh-pack kosher dill cucumbers so that jars can be used to inoculate commercial scale cucumber fermentation tanks. A procedure is also described to transfer lactic acid bacteria from frozen storage in MRS broth into cucumber juice and commercial jars of kosher...

Jamming avoidance responses (JARs) are exhibited by pairs of pulse type electric fish that discharge with similar frequencies whenever their individual pulses are about to coincide: responses consist of the transient shortenings in inter-discharge intervals in the fish with the higher frequency. This study describes and models novel forms of JARs observed in sexually mature male or female Brach...

Many Drosophila tissues (other than embryos or egg chambers) are too large, delicate, transparent, or buoyant for manipulation in suspension. Tissues such as spermatocytes, spermatids, and imaginal disks are difficult to handle in suspension and are more appropriately fixed on slides or coverslips for whole-mount fluorescent in situ hybridization (FISH). As described in this protocol, the hybri...

Novaluron, a new chitin synthesis inhibitor type of insect growth regulator, was evaluated in the laboratory and field against larvae of the mosquito Aedes aegypti (L.). In the laboratory, the technical material showed a high level of activity against 2nd and 4th instar larvae. The inhibition of emergence (IE) was 100% at concentrations of 0.25 to 1.0 μg/L. Second instars were slightly more sus...

The megalithic jar sites of Laos (often referred to as the Plain Jars) remain one Southeast Asia’s most mysterious and least understood archaeological cultures. sites, recently inscribed UNESCO World Heritage, host hollowed stone jars, up three metres in height, which appear scattered across landscape, alone or clustered groups more than 400. Until now, it has not been possible estimate when ja...
