In this paper we consider the extent of our knowledge of global beetle diversity. Depending on the estimates adopted, some 70–95% of all beetle species remain to be formally described, and at the current rate of progress it could be more than 200 years until the task is completed. One of the reasons for this is the difficulty of adequately sampling tropical beetle faunas and thereby ensuring su...

Whether to develop inbred cultivars or F1 hybrids is a dilemma faced by many rice (Oryza sativa L.) breeders. This could be partially answered if one could select superior recombinant inbred lines with an equal yielding ability and good quality traits from commercial F1 hybrids. Thus, it was attempted in this study to select superior inbred lines from 2 commercial F1 hybrids after application o...

A survey is given of experimental studies of electron attachment and recombination in dense molecular media, from which information on the effect of van der Waals potentials or on the existence of surrounding molecules on these processes is obtained.

An optical study has been made of La0 ·7Ca0 ·3MnO3 and La0 ·8Li0 ·2MnO3 in the infrared spectral region (100 cm−1 to 4000 cm−1). The transmission of all samples is negligible. The photoconductive response is also unmeasurable. The data reported are therefore restricted to reflectivity measurements. At room temperature, both materials exhibit similar ‘bending’ and ‘stretching’ phonon modes, asso...

This paper described the archtecture of a hyperdocument system intended to provide access to a coherent body of knowledge, consisting of structured knowledge, text, graphics, data and executable models. The main focus of the research is in intermediate structure added to the documents to support the links between the structured knowledge and the textual knowledge. The system is implemented in a...
