A cDNA clone for NADPH : protochlorophyllide oxi­ doreductase from barley was subcloned for production of antisense-mRNA. This enabled heterologous hybridi­ zation with RNA from cress seedlings (Lepidium sativum L.). The mRNA level for N A DPH : protochlorophyllide oxidoreductase did not decrease in cress seedlings during irradiation with continuous far-red or white light up to 12 h. The amount...

There are a number of challenges in applying high-spatial resolution satellite image data for analysis of larger urban areas. This paper explores the use of object-oriented image analysis approaches in mapping urban land cover and land use. The study is based on seven IKONOS images covering the Santa Barbara, CA region. Image processing included geometric and atmospheric correction and image se...

THE dispersed cellulose component which is found in white mustard seed mucilage [Bailey and Norris, 1932] and in quince seed mucilage [Schmidt, 1844; Kirchner and Tollens, 1874; Renfrew and Cretcher, 1932] has now been obtained from the mucilage of cress seed, Lepidium sativum. The present communication, which deals mainly with the chemistry of this seed mucilage, falls into three sections: (1)...

Barbara Mary Pycraft was born on 22 February 1910. Her father, William Pycraft, was an ornithologist on the staff of the Natural History Museum, South Kensington, and the author of several books. After reading history at London University she was appointed research assistant at the Wellcome Medical History Museum, still in Wigmore Street, in the spring of 1931. Her first work involved the class...

The inhibitory activity of aqueous extracts of field-grown sorghum (Sorghum bicolor cv. Bird-a-boo) herbage and roots was quantitatively indexed by three aspects of cumulative cress (Lepidium sativum cv. Curlycress) seed germination: the germination onset; weighted mean rate; and final germination percentage. Extract potency was greatest for herbage collected four weeks after planting but decli...

It is argued that languages constructs for defining services are important in providing well-structured descriptions. This view is illustrated with two service definition languages, Anise (Architectural Notions In Service Engineering) and Cress (Chisel Representation Employing Structured Specifications). Anise is a mainly textual notation for defining services through the composition of simpler...
