Rapid Bacterial Detection and Identification of Bacterial Strains Using Machine Learning Methods Integrated With a Portable Multichannel Fluorometer

IEEE Access, 2023
Rapid and sensitive bioburden detection is of paramount importance in different applications including public health, and food and water safety. To overcome the traditional limitations of bacterial detection i.e., lengthy culture time, and complicated ...

Simultaneous illumination method: application in a two-channel emission fluorometer with multi-wavelength excitation [PDF]

, 2011
We developed a new illumination method called the simultaneous illumination method. This method does not require synchronization between light sources and sensor signals, which drastically simplifies the instrumentation. As a proof-of-concept, we applied

Assessment of field fluorometers

Water Science and Technology, 2014
Two field fluorometers, devoted either to natural organic matter (NOM) or to tryptophan-like fluorescing substances, were tested for the characterization of a large set of water samples (n = 263) impacted to various degrees by untreated or poorly treated urban sewage. Both fluorometers yielded consistent results when testing discrete samples.

PHOTOSYNTHETHIC PARAMETER ASSESSMENT OF CORAL ZOOXANTHELLAE OF Acropora aspera AND Favites abdita USING MAXI I-PAM SYSTEM IN HERON ISLAND, GREAT BARRIER REEF, AUSTRALIA [PDF]

, 2006
Zooxanthellae, which reside inside the coral host, have been an essential component in coral ecosystem studies. While residing inside their host, zooxanthellae photosynthesize provide energy and nutrients to coral. Objectives are to observe the impact of

Subsurface chlorophyll maxima reduce the performance of non-photochemical quenching corrections in the Southern Ocean

Frontiers in Marine Science
Non-photochemical quenching (NPQ) within phytoplankton cells often causes the daytime suppression of chlorophyll fluorescence in the Southern Ocean. This is problematic and requires accurate correction when chlorophyll fluorescence is used as a proxy for

Diagnosis of Induced Resistance State in Tomato Using Artificial Neural Network Models Based on Supervised Self-Organizing Maps and Fluorescence Kinetics

Sensors, 2022
The aim of this study was to develop three supervised self-organizing map (SOM) models for the automatic recognition of a systemic resistance state in plants after application of a resistance inducer. The pathosystem Fusarium oxysporum f. sp.

Automated fluorometer for uranium analysis [PDF]

, 1978
An utomated fluorometer has proven to be a valuable analytical tool for analyzing natural waters for the Uranium Resource Evaluation (URE) project. Uranium is isolated from potential quenching ions and concentrated by extraction with tri-n-octylphosphine
