Forty-seven eyes from 25 patients with neurological disease were examined with an automatic computerized perimeter primarily intended for glaucoma. Manual kinetic and static perimetry with Goldmann's instrument was used for comparison. In 32 fields, the automatic method disclosed all defects that had been found by manual perimetry. Furthermore, it detected three small defects that had been missed

An apparatus for static perimetry of the central visual field at 64 points is described. The testing is fully automatic: the test logic is programmed into a mini-computer and the results are plotted as a diagram in polar coordinates. A few cases with small or medium sized visual field defects have been analyzed by conventional methods and by the automatic instrument with satisfying results.

An instrument for automatic static perimetry at 14 points across a meridian was constructed and used in a pilot study. The machine was controlled by a computer and the subjects responded to the light stimuli by pressing one of two push-buttons. Most people investigated readily understood the rules at testing. "Blunders" made by the subject were, however, so common, that allowance had to be made in

Contrary to what practice suggests, social media platforms may not be an appropriate forum for communicating with civil society about sustainability issues such as climate change. Misinformation campaigns are distorting the line between fact and falsity on social media platforms, and there has been a profound shift in the way that social media users consume and interact with information. These con

It has often been the presumption that reverse cross-linguistic influence requires an advanced fluency in the second language. This assumption has led to much of the research focusing on the impact of the speaker’s existing languages towards their second or third language. Our mental lexicons are, however, in a constant state of change through learning, forgetting, and consolidation, and we should

Aqueous two-phase systems are generated by mixing aqueous solutions of two water-soluble polymers, or a polymer and a salt. These systems offer extremely mild conditions for separation of cells, organelles, proteins and other biomolecules, in biochemical processes. Considerable attention has been directed towards the use of the two-phase systems in several areas of biotechnology. The present paper

Conventional aqueous two-phase extraction by spontaneous partitioning has often problems with low specificity. The introduction of an affinity ligand into one of the phases has been attempted to enhance the specificity of protein partitioning (1-7; Chapters 29-31). However, this procedure still has some limitations in the effective removal of impurities as well as recovery and reuse of the ligand.
