In the past fifty years, no recorded case of botulism has been attributed to surface ripened cheese (NIeyer and Eddie, 1950). When cheese spread was prepared from one type of surface ripened cheese, botulinum toxin was demonstrated in only one out of several million jars (Dauer, 1952). The fact that botulism was never observed with the original surface ripened cheese from which cheese spreads w...

A total of 227 strains of viridans streptococci were simultaneously identified on the Minitek Miniaturised System (BBL) and by a conventional method according to Colman and Williams. The Minitek discs were each overlaid with a drop of sterile liquid paraffin, and the trays were incubated in GaSPak jars (BBL) with CO2 generator envelopes. Identification was possible three to four days earlier th...

We examined haptic perception of the horizontal in visually impaired people. Blind people (late blind and congenitally blind), persons with very low vision, and blindfolded sighted individuals felt raised-line drawings of jars at four angles. They had to demonstrate their understanding that water remains horizontal, despite jar tilt, by selecting the correct raised-line drawing given four choic...

The relative impact of control-, acceptance-, and information-based approaches in targeting a midlevel fear of spiders among college students was evaluated. Participants listened to a brief protocol presenting one of the three approaches before completing the Perceived-Threat Behavioral Approach Test (PT-BAT; Cochrane, Barnes-Holmes, & BarnesHolmes, 2008). During the PT-BAT, participants placed...

I. Early Pulsed and Oscillating Discharges André Anders, Fellow Lawrence Berkeley National Laboratory, University of California, 1 Cyclotron Road, Berkeley, California 94720-8223 [email protected] ABSTRACT The early development of arc plasma physics is closely related to the development of suitable sources of electrical energy. The harnessing of electrostatic charge in Leyden jars (early capacito...

JCB • VOLUME 214 • NUMBER 4 • 2016 360 Hari Shroff was born in India, but grew up in England and the US. He became interested in animals and plants at an early age—his parents would take Shroff and his brother out to local parks, fi elds, and woods—and he has vivid memories of trying to raise tadpoles in jars and being fascinated by reptiles and amphibians. In one of his earliest scientifi c ex...

In northern Vietnam, copepods of the genus Mesocyclops were used for biological control of Aedes aegypti, the principal vector of dengue viruses, by inoculation into wells, large cement tanks, ceramic jars, and other domestic containers that served as Ae. aegypti breeding sites. The use of Mesocyclops was complemented by community participation with respect to recycling to eliminate unused and ...

Aim—To investigate the eVect on urine culture results and their clinical interpretation of delaying the processing of urine samples in which boric acid had been used as a preservative. Methods—792 mid-stream specimens of urine from patients attending their general practitioner were received in borate containing plastic jars. The specimens were cultured upon receipt, stored at room temperature, ...

Cordycepin is one of the most important bioactive compounds produced by species of Cordyceps sensu lato, but it is hard to produce large amounts of this substance in industrial production. In this work, single factor design, Plackett-Burman design, and central composite design were employed to establish the key factors and identify optimal culture conditions which improved cordycepin production...

The migration of epoxidized soy bean oil (ESBO) from the gasket in the lids of glass jars into foods, particularly those rich in edible oil, often far exceeds the legal limit (60 mg/kg). ESBO was determined through a methyl ester isomer of diepoxy linoleic acid. Transesterification occurred directly in the homogenized food. From the extracted methyl esters, the diepoxy components were isolated ...
