Introduction Infectious bovine keratoconjunctivitis (IBK) is caused by a Gram-negative bacterium, Moraxella bovis. It is characterised by acute contagious ophthalmia and it spreads rapidly among cattle in a herd. M. bovis is generally present on the mucous membranes of healthy animals and is considered to be an opportunistic pathogen (Quinn et al., 1994; Gyles and Thoen, 1993). The bacterium is...

Use of anabolic steroids has for some time been widespread among competitive sportsmen and women, who selfadminister doses of up to 100 times the recommended therapeutic dose, and use combinations of multiple oral and injectable preparations (a practice known as'stacking'). Often these are preparations intended for veterinary use, or of questionable origin, purity or authenticity. They are take...

The growing context-sensitive languages have been classiied through the shrinking two-pushdown automaton, the deterministic version of which characterizes the class of generalized Church-Rosser languages (Buntrock and Otto 1995). Exploiting this characterization we prove that this latter class coincides with the class of Church-Rosser languages that was introduced by McNaughton, Narendran, and ...

Miranda-Filho et al. in their recently published paper entitled “Cancers of the brain and CNS: global patterns and trends in incidence” provided a global status report of the geographic and temporal variations in the incidence of brain and CNS cancers in different countries across continents worldwide. While the authors confirm the role of genetic risk factors and ionizing radiation exposur...

A classification method for the automatic detection of linear objects in synthetic aperture radar (SAR) images is proposed. It is based on feature extraction using a line model, some basic cues from human vision and a neural network classification considering local and global parameters. The method is applied to ERS-1 SAR images to derive the locations of lake and forest boundaries. didate. Eit...

Understanding the textual distinction between spokenness-informality and writtenness-formality serves many purposes. It can facilitate text mining, improve parser accuracy, offer better appraisals of student writing, and may also facilitate better interpretations of experimental data. Previous studies of such textual variation (e.g., Biber, 1988, Louwerse et al., 2004) have failed to produce a ...

M ortality from cancer is usually due to metastatic disease, which represents the uncontrolled proliferation of cells that no longer respond to the normal regulatory controls of the organism (Silverberg et al, 1990). There are several factors which may accelerate metastasis, including: increased extracellular matrix degradation, due to increased matrix metalloproteinase (MMP) activity, which ca...

Image segmentation is the process of separating or grouping an image into different parts . These parts normally correspond to something that human beings can easily separate and view as individual objects. Computers have no means of intelligently for recognizing objects, and a large number of different methods have been developed in order to segment images, ranging from the simple thresholding...

Tenascin and thrombospondin are multimeric glycoproteins with restricted distributions in the embryonic extracellular matrix (for review see Chiquet-Ehrismann, 1991; Erickson and Bourdon, 1989; Frazier, 1991; Sage and Bornstein, 1991). Immunohistochemistry has revealed that tenascin and thrombospondin are particularly abundant in the developing central and peripheral nervous systems as well as ...
