Predicting firefighting simulation tasks performance from firefighters' specific fitness tests.

BackgroundPrevious studies have examined the correlation between fitness characteristics and firefighter's job performance.ObjectiveThis study was to examine the ability of firefighters' specific fitness tests to predict firefighter's job performance.MethodsFifty fire academy trainees (48 males and 2 females, age = 27.

Application of molecular biological techniques to analyze Salmonella seasonal distribution in stream water.

Salmonella is a leading cause of waterborne diseases. Salmonella can survive for a long time in aquatic environments, and its persistence in the environment is of great concern to public health. Nonetheless, the presence and diversity of Salmonella in the aquatic environments in most areas remain relatively unknown.

Evaluation of different analysis and identification methods for Salmonella detection in surface drinking water sources.

The standard method for detecting Salmonella generally analyzes food or fecal samples. Salmonella often occur in relatively low concentrations in environmental waters. Therefore, some form of concentration and proliferation may be needed.
