Hawaii is home to over 60 ant species, including five of the six most damaging invasive ants. Although there have been many surveys of ants in Hawaii, the last island-wide hand-collection survey of ants on Oahu was conducted in 1988-1994. In 2012, a timed hand-collection of ants was made at 44 sites in a systematic, roadside survey throughout Oahu. Ants were identified and species distribution ...

BACKGROUND After the invasion of Iraq in April 2003, coalition forces have remained in the country in a bid to maintain stability and support the local security forces. The improvised explosive device (IED) has been widely used by the insurgents and is the leading cause of death and injury among Coalition troops in the region. METHOD From January 2006, data were prospectively collected on 100...

This paper establishes a new mobile electronic toll collection (m-ETC) by integrating mobile communication with radio frequency (RF) communication on microprocessor control with an e-commerce business model. A simple ETC system architecture and protocol for e-transactions from vehicles to toll stations is proposed to complete toll interaction on wireless environment. A software flow through Int...

This paper describes the first phase of a three year PhD research project which aims at extracting road and roadside information accurately and robustly from airborne sensor data and assessing its suitability for integration in a spatial analysis system. The context for this research is road safety and the requirements of the European noise directive for noise mapping. Phase 1 concentrated on u...

Diverse contaminants released into the environment through progress of urbanization and industrialization adversely affect human health. Among various sources of contaminants, especially, in big cities, automobiles play a significant role in aggravating the pollution. Various pollutants viz., heavy metals (Pb, Mn, Ni, Zn, As, Hg, Cd) and Polyaromatic hydrocarbons (Benzo-apyrene, fluoranthene, p...

This study investigates the potential hazard to vehicles of excessive roadside edge wedge (defined as a wide, deep edge treatment) and develops a safety design countermeasure. Using the Human Vehicle Environment (HVE) simulation tool, a typical driving scenario, road profile, and vehicle and driver behavior were selected to represent high risk situations. Wedge heights and slopes were modeled a...

This study was conducted to determine the prevalence of Salmonella typhi in Calabar Municipality. One thousand five hundred (1500) stool specimens were collected from food handlers, i.e. food-hawkers, canteen workers, restaurant workers and people working in drinking parlours. Eight hundred and twenty (54.7%) males and 680 (45.3%) females, aged between 5 and 55 years, participated in the study....
