We describe a case of a diagnostically difficult stroke mimic, cephalic tetanus. 1 Currently there are 12–15 cases of tetanus reported annually in the United Kingdom, 2 but worldwide it accounts for one million deaths, 80% being in Africa and South East Asia. 3 Tetanus is caused by infection with clostridium tetani.

Grazing and grazing management terminology in southern Africa
Proceedings of the Annual Congresses of the Grassland Society of Southern Africa, 1967In order to avoid misunderstanding arising in discussions and from the literature on grazing management problems in Southern Africa a proposed list of terms and definitions to cater for all grazing situations and concepts is presented. The terms are classified into two groups, those dealing with properties of the vegetation and those dealing with ...

THE PATTERN OF GRAZING IN ‘CONTINUOUSLY’ GRAZED SWARDS
Grass and Forage Science, 1969The frequency and severity of defoliation of small sample areas, 8 × 8 cm, was studied in swards of S37 cocksfoot which were maintained at different levels of leaf‐area index by continuous grazing with lambs. By varying the number of lambs grazing a plot, the LAI was maintained at three approximately constant levels, 5.3 (H), 4.1 (M), and 3.0 (L).

Publisher Summary Grazing intensity refers to the amount of quantitative animal demand for forage placed upon the standing crop forage or forage mass, and to the resulting level of defoliation made during grazing. After several years of research some grazing intensity studies were found to include no stocking rate that resulted in overgrazing; in ...

It is hard to see, given previous analysis ([1][1]), the point of redefining “nonequilibrium” systems as “all systems that are not at equilibrium,” as L. Gillson and M. T. Hoffman do in their Perspective “Rangeland ecology in a changing world” (Perspectives, 5 Jan., p.

Grazing is more than just defoliation of plants. The impact of herbivory affects ecosystem structure and function, both above and below ground. Ultimately, effects of herbivory are expressed to varying degrees at many levels of the ecosystem. Herbivory has been shown to affect plant physiology, morphology, and genetics. Plants have evolved many ways to

A correlation was found between the seasonal epiphyte cycle in Lake Memphremagog (Québec‐Vermont), with a maximum in mid‐June, and the abundance of grazers (mainly oligochaetes and chironomids). Evidence for a cause and effect relationship was provided by exclosure‐enclosure experiments. When grazers were excluded epiphyte biomass did not decline as it

Grazing-incidence spectrograph
Applied Optics, 1994A novel compact spectrograph, based on double diffraction by a strip-shaped grating at a grazing angle combined with a tuning mirror, is theoretically discussed. In this configuration the emerging light illuminates a large number of grooves, leading to high spectral resolution.

The potentialities of photographic transaxial tomographic methods are discussed. It is shown that unfiltered, transaxial tomographic summation images can yield high-quality tomograms of high-contrast objects. A direct and efficient photographic method for recording transaxial tomograms (grazing incidence tomography) is demonstrated, and various means ...
