  • A novel experimental design for examining Bryophyte response to increased Ultraviolet radiation

    Bryophytes were among the earliest colonizers of terrestrial environs, and despite their interesting life histories and population dynamics, they are rarely used in undergraduate introductory biology labs. In an inquiry-based laboratory exercise for introductory biology, students implement a controlled experiment to investigate effects of increased ultraviolet radiation (UVR) exposure on ...

  • White clover nodulation index in heavy metal contaminated soils– a potential bioindicator

    Received for publication January 10, 2008. The morphological effects of heavy metal stress on the nodulation ability of Rhizobium spp. and growth of white clover (Trifolium repens L.) were studied in the laboratory under controlled conditions. Fourteen topsoils were collected from an area with elevated metal concentrations (Cd, Zn, and Pb). White clover was cultivated using a specialized ...

  • Analysis of Foodborne Disease Outbreaks for Improvement of Food Safety Programs in Seoul, Republic of Korea, from 2002 to 2006

    Foodborne disease (FBD) is a common food safety problem in Seoul, Republic of Korea. To identify target areas for improvement of the food safety programs, FBD outbreaks from 2002 to 2006 were analyzed with regard to facility, monthly occurrences, and causative agents. A total of 147 FBD outbreaks were reported, with an average of 29.4 FBD outbreaks per year and 49 cases per outbreak. Restaurants ...

  • Using Health Inspection Scores to Assess Risk in Food Services

    This study gathered health inspectors’ opinions about appropriate weightings of critical, noncritical, and repeat violations under the current food inspection system, and developed a classification of violations for high-, medium-, and low-risk restaurants.
