Ethnoveterinary medical practice is widespread among herdsmen and village livestock producers in northern Nigeria where livestock in the country are concentrated. For most of these livestock owners, modern veterinary inputs and services are not readily available and are relatively expensive. Traditional remedies are locally available and cheaper. Our questioning of 50 herdsmen and village lives...

Recent research suggests that, due to misconfiguration, DNS reliability and performance is not always as good as it should be. This paper therefore investigates the correct configuration of DNS zones, by checking if main configuration requirements, recommendations and bestpractices rules have been followed. Our research shows that almost one out of four zones fail to pass one or more of our tes...

Several primate taxa show evidence of natural hybridization, and recent genomic analyses of modern and archaic humans have revealed the prevalence of hybridization during the evolutionary history of our own lineage. Thus interest in understanding how natural hybridization occurs in our closest relatives, the nonhuman primates, has grown rapidly. However, studies of the process and dynamics of h...

This paper investigates how the psychological notion of comfort can be useful in the design of robotic systems. A review of the existing study of human comfort, especially regarding its presence in infants, is conducted with the goal being to determine the relevant characteristics for mapping it onto the robotics domain. Focus is placed on the identification of the salient features in the envir...

With the aid of numerical experiments we examined the dynamical stability of fictitious terrestrial planets in 1:1 mean motion resonance with Jovian-like planets of extrasolar planetary systems. In our stability study of the so-called "Trojan" planets in the habitable zone, we used the restricted three-body problem with different mass ratios of the primary bodies. The application of the three-b...

Spontaneous interaction among humans and things in pervasive computing systems is often based on the spatial outreach to which an entity can interact with another entity, often referred to as ”zone of interaction”. Usually technological sensors for proximity and distance, like radio, ultrasound or microwave, are used to perceive and track the presence, activity and utterance of entities in the ...

THE EDITORIAL BY ROSAMOND NAYLOR, “Offshore aquaculture legislation” (8 Sept., p. 1363), suggests that the motivation for moving aquaculture into the open ocean is that “marine f ish farming near the shore is limited by state regulations.” Although unworkable regulations may exist in a few states, in the larger scheme this is irrelevant. Of the offshore aquaculture projects currently under way,...
