A previously developed multiple regression algorithm was used as the basis of a stochastic model to simulate worm burdens in sheep naturally infected with Haemonchus contortus over five consecutive Haemonchus seasons (November to January/February) on a farm in the summer rainfall region in South Africa, although only one season is discussed. The algorithm associates haemoglobin levels with worm...

Music genres allow to categorize musical items that share common characteristics. Although these categories are not mutually exclusive, most related research is traditionally focused on classifying tracks into a single class. Furthermore, these categories (e.g., Pop, Rock) tend to be too broad for certain applications. In this work we aim to expand this task by categorizing musical items into m...

With the expansion of the Internet, system administrators cannot keep up with the new viruses and security vulnerability information. As Code Red and the Nimda Worm spread globally in 2001, the understanding of how to prevent such viruses was not sufficiently disseminated from system administrators to users. Although companies like Microsoft and CERT published security information, many users d...

The reliability of different egg counting methods for estimating the intensity of Trichostrongylus tenuis infections in red grouse, Lagopus lagopus scoticus, was investigated in the autumn, when grouse may harbour high parasite intensities. Possible limitations to the use of these methods were also examined. Faecal egg counts were found to accurately estimate T. tenuis worm intensities, at leas...

Active worms spread in an automated fashion and can flood the Internet in a very short time. Modeling the spread of active worms can help us understand how active worms spread, and how we can monitor and defend against the propagation of worms effectively. In this paper, we present a mathematical model, referred to as the Analytical Active Worm Propagation (AAWP) model, which characterizes the ...

The influence of microclimate on numbers of third-state larvae of haemonchus contortus and Haemonchus placei in four strata of irrigated Kikuyu pasture was assessed. On 36 different, interspersed days three replicates of pasture samples were collected on three occasions per day from 1990-1992 for larval recovery and the log10 mean counts of the larvae recovered were analysed by use of ANOVA mod...

This is due to the ability of active worms to automatically propagate themselves and co...

Small strongyles (‘small red worm’) are the most common and harmful intestinal worm of horses worldwide and account for 95% of faecal worm egg count burdens. The adult worms are small (1-2 cm long) and live in the horse’s large intestine (Fig. 1). The adult worms lay eggs which pass onto the pasture in the manure. Larvae (immature worm) hatch from the egg and cleverly migrate up blades of grass...
