IT WOULD be impossible in a short essay to cover the whole ground of research on viruses, including those infecting vertebrates, insects, plants, bacteria and other organisms. Attention will accordingly be devoted particularly to those aspects of virology of nterest in medicine. (This is the more appropriate as this symposium has been organized in honour of Sir Charles Stuart-Harris, who has so...

An isozyme study on the single population of the dioecious, clonal, and rhizomatous plant species Mercurialis ovata in Switzerland was carried out to determine whether small, isolated, outbred populations show low genetic variation, and whether most sexual events within such populations are sibmatings. Although the number of multilocus genotypes was very high (100%), most individuals were close...

Previous chapters considered the problems of information retrieval experiment in general, and particular types of experiment. This chapter looks at information retrieval experiment over the last twenty years as a whole, to see what the actual tests which have been carried out show. I shall not attempt an exhaustive review of this work. I shall seek rather to characterize it by referring on the ...

The Planned Parenthood Committee of Phoenix was established in 1942 to expand Arizona women's access to family planning [2] resources. The Planned Parenthood Committee of Phoenix was formed through the merging of The Mother's Health Clinic in Phoenix, Arizona, with the national Planned Parenthood Federation of America. The clinic was primarily based within the Phoenix Memorial Hospital campus b...

We examine cross-region capital mobility in China and track how the degree of mobility has changed over time. The effects of fiscal and redistributive activities of different levels of government in China on private capital mobility are taken into account. Our results indicate that there is a significant improvement in capital mobility over time in China, particularly for private capital in the...

Several classes of isozyme characters are recognized including the number of genes that control a given enzyme system, intralocus and interlocus heteropolymer assembly, tissuespecific gene expression, developmental patterns of enzyme expression, and post-translational modification of gene products. All of these characters can be of value in systematic studies although few applications have been...
