The working relationship between the general practitioner and the health visitor
(1984-05)
The views of 40 health visitors from the Cambridge health district on their working relationship with general practitioners are presented. Patterns of attachment and facilities at the work base are described. The health ...
Negatively supercoiled DNA from plants infected with a single-stranded DNA virus
(1984-02-14)
A method for isolating covalently closed circular double-stranded DNA from plants infected with the geminivirus, tomato golden mosaic virus, is described. Ethidium bromide titration showed this DNA to be negatively supercoiled ...
A high resolution hydrogen line survey of Messier 31. I : Observations and data reduction
(1984-02-01)
New observations with the Westerbork Synthesis Radio Telescope are presented of M31 in the 21 cm line of neutral atomic hydrogen. The observations and calibration are described, and the various stages of data reduction are ...
A Structural Investigation of the Epstein—Barr (EB) Virus Membrane Antigen Glycoprotein, gp340
(1984-02)
Epstein—Barr (EB) virus membrane antigen (MA) glycoprotein (gp340) purified by a molecular weight-based technique has been subjected to biochemical analysis. Following treatment with glycosidases or tunicamycin during ...
Effect of cellulose xanthate on splash dispersal of Pseudocercosporella herpotrichoides spores
(1984)
Cellulose xanthate reduced dispersal of Pseudocercosporella herpotrichoides spores from wheat straw by simulated rain.
Infrared and optical polarimetry of AM Herculis
(1984)
Circular polarization observations of AM Herculis have been obtained at wavelengths from 0.55 micron (V) to 2.2 micron (K) using a simultaneous three-channel polarimeter. Polarizations of up to 20 per cent were observed ...
Immunocytochemical localization of the elongation factor Tu in E. coli cells
(1984)
The localization of the elongation factor Tu (EF-Tu) in ultrathin cryosections of E. coli cells was determined with the electron microscope using a highly specific immunological labellin technique. EF-Tu is distributed ...
The extraction of total RNA by the detergent and phenol method
(1984)
Successful extraction of RNA depends on the quantitative recovery of pure nucleic acids in an undegraded form. In practice, this means that a selective extraction process is required to remove all the unwanted cellular ...
