17 18 The prevalence of mycobacterial infection among lactating Fulani cows was investigated in 19 the Federal Capital Territory (FCT), Abuja and Kaduna State of Nigeria. Tuberculin testing 20 using single comparative intradermal tuberculin test (SCITT) showed a 14.6% positive, 4% 21 doubtful and 81.4% negative reactors. Mycobacterial infection was found to be present in the 22 nomadic (constan...

Nomadic computing is a phenomenon in computing and communications that is spreading rapidly. At this stage of its technology, the key problems and the basic understanding of its underlying principles are only beginning to be identified. Analysis and design tools are needed to assist in its development. In this paper, we discuss the nature of the tools and what one might look for in the way of a...

In the increasingly wireless world of data communications; laptops, palmtops and other nomadic computers are appearing that have built-in, wireless access (e.g. cellular, radio, infrared, satellite access) to one or more wireless networks around them. Applications executing on these nomadic computers need to be able to locate services and enter into one or more service-level agreements with ser...

Recent advances in the Domain Name System (DNS) and the Dynamic Host Configuration Protocol (DHCP) have enabled a new approach to supporting mobile users: location independent naming. In this approach, machines use the same hostname from any internet location, but use an IP address that corresponds to their current location. We describe a protocol that implements location independent naming for...

Desktop browsers are excellent for browsing web sites but they keep users tethered. Wireless browsing technologies such as WAP and i-mode untether nomadic users by making these services available on the move. However, it is not clear if users will be satisfied with free form browsing offered by these wireless technologies. We believe that in addition to free form web browsing, nomadic users wil...

This research study identified social challenges that knowledge workers in the Swedish organization TeliaSonera (Telia) face when utilizing wireless technologies to conduct work on the move. Upon collecting the relevant research data, five problem areas were identified: work and life balance, addiction, organizational involvement, nomadic work and control, and individual productivity. Each prob...

Gravitational microlensing has revealed an extensive population of “nomadic” planets not orbiting any star, with Jupiter-mass nomads being more populous than main sequence stars. Except for distant objects discovered through microlensing, and hot, young nomads found near star formation regions, to date only a small number of nomad candidates have been discovered. Here I show that there should b...

Ubiquitous computing embraces both nomadic computing and infrastructure-rich interactive workspaces. Although most effort in these areas to date has focused narrowly on one domain, there are interesting challenges at their intersection. To start a discussion on how some of the benefits of interactive workspaces can be provided to nomadic users, we present MeetingMachine, a digital media project...

INTRODUCTION Zoonotic enteric parasites are ubiquitous and remain a public health threat to humans due to our close relationship with domestic animals and wildlife, inadequate water, sanitation, and hygiene practices and diet. While most communities are now sedentary, nomadic and pastoral populations still exist and experience unique exposure risks for acquiring zoonotic enteric parasites. Thro...
