Abstract: A scale assembly for weighing potentially hazardous materials comprise a containment deck designed to support a container from which materials are dispensed. The containment deck is preferably provided with sufficient storage capacity to capture spillage or leaks from the container and is supported on a low-profile platform supported in turn by load cells which generate signals indicative of the weight of the contents of the container and of any spillage within the containment deck. The containment deck is further equipped with a level detector typically positioned near the bottom of the deck for generating signals indicating the presence of leakage or spillage from the container.

Abstract: A stable transformed insect cell line has been achieved by infecting an insect cell culture with fluid obtained from a female parasitoid wasp, such as Glyptapanteles indiensis. The fluid contains polydnavirus DNA capable of integrating into the host cell genome. Susceptible insect cells include both Lepidopteran and Coleopteran cells.

Abstract: A method has been found to select the most virulent biotypes from a wild-type entomopathogenic virus by selection of desirable characteristics after serial passages through in vivo and in vitro systems. Using this method, a strain of Lymantria dispar NPV virus was isolated which had increased biological activity and increased speed of kill.

Abstract: A strain gauge scale is disclosed comprising a platform having two weighing discs, each disc being connected with the platform by means of three load cells, each of which has a multiple component strain gauge associated therewith.
