The phenology and sex ratios of three hover fly species on Canterbury farmland, New Zealand were recorded weekly from five yellow watertraps from October 15, 1993 to January 31,1997. Gut fullness, egg number and pollen content were recorded weekly from September 8, 1994 to July 25, 1996. Catches of Melanostoma fasciatum (Macquart) and Melang\ma novaezelandiae (Macquart) were higher during the s...

The Prevalence and role of mouth parasites in patients attending Out Patient Department of Khyber College of Dentistry, Peshawar, North West Frontier Province of Pakistan were investigated. The prevalence of Entamoeba gingivalis and trichomonas tenax estimated in 150 patients belonging to rural and urban localities in North West Frontier Province of Pakistan during February 2006 to July 2006. A...

STATEMENT OF THE PROBLEM Trichomonas tenax and Entamoeba gingivalis are commensal protozoa which inhabit the human oral cavity. These parasites are found in patients with poor oral hygiene and might be a reason for progressive periodontal diseases. PURPOSE The aim of this study was to evaluate the effect of nonsurgical periodontal treatment on the frequency of these protozoa in saliva and pla...

Research suggests that spirituality is important to a large percentage of the older adult population and serves as a promoter of healthy aging. In this qualitative research I conducted and analyzed multiple interviews with 6 women aged 80 and older. Using multiple in-depth interviews I explored the interplay between spirituality and resilience over the life course. A grounded theory analysis of...

In this study, bioavailability of polychlorinated biphenyls (PCBs) in soil samples aged for various time intervals (7 days, 1 and 5 months) was assessed by in vivo tests using mice. The in vivo bioavailability of PCBs in soil ranged from 45% (PCB180 in soil aging for 5 month) to 119% (PCB52 in soil aging for 1 month), indicating that not all PCBs was available for absorption after ingestion of ...

This work studies potential ways of integration of two techniques for fault detection, isolation, and identification in dynamic systems: Lydia-NG suite of diagnosis algorithms and Consistency-based Diagnosis with Possible Conflicts. By integrating both techniques, LydiaNG will benefit from a more efficient fault detection and isolation task, and Possible Conflicts will benefit from the identifi...

Physiologically based in vitro methods have been developed to measure bioaccessibility of organic contaminants in soils. However, bioaccessibility of hydrophobic organic contaminants (HOCs) can be underestimated by in vitro tests if gastrointestinal (GI) solution fails to provide sufficient sorption sink for HOCs. To circumvent this drawback, Tenax was included in GI solution as sorption sink t...

Biota-sediment accumulation factors (BSAF) were calculated for Diporeia spp. and oligochaete worms exposed to polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) from field-collected sediment. These data were compared to the contaminant fraction extracted from sediment with Tenax resin using a 24 h extraction. A previous laboratory study suggested a linear relationship ...
