Application of Ames Salmonella Test to Nakdong River in Korea.

Mapping Levees Using LiDAR Data and Multispectral Orthoimages in the Nakdong River Basins, South Korea

Mapping levees is important for analyzing levee surfaces, assessing levee stability, etc. Historically, mapping levees has been carried out using ground surveying methods or only one type of remote sensing dataset. This research aims to map levees using airborne topographic LiDAR data and multispectral orthoimages taken in the Nakdong River Basins. Levee surfaces consist of multiple objects wit...

Optimal Operating Rules for Integrated Reservoir System with Idp in the Nakdong River Basin,korea

The purpose of this study is to develop a new enhanced IDP (Incremental Dynamic Programming) model which is suitable for analysis of operation policies of multipurpose and multi-unit water resources system. The proposed new IDP approach deals with the optimization of trajectories is applied to a four reservoir system in the Nakdong River. The results of optimization in system operation show sig...

Application of bacteriophages to control Salmonella Enteritidis in raw eggs

Background: Salmonella, a bacterial genus of more than 2500 serotypes is considered as the most significant foodborne pathogen causing infections in humans and animals. Increased antimicrobial resistance and persistence of antimicrobial residues in food matrices warrants the need for alternative infection management strategies. Aims: The present study aimed to isolate and evaluate the lytic act...

Activity of quinolones in the Ames Salmonella TA102 mutagenicity test and other bacterial genotoxicity assays.

Eight quinolones were examined for their bacterial mutagenicity in the Ames Salmonella TA102 assay and for their effects in other bacterial genotoxicity assays. In the quantitative Ames plate incorporation assay, all eight quinolones induced His+ deletion reversion in Salmonella tester strain TA102, with maximum reversion observed at about two to eight times the MIC. The quinolones also induced...
