This study proposes a comprehensive approach to investigate water resource contamination by pesticides under the specific climatic and hydrological conditions of the Sudano-Sahelian climate. Samples were collected from tradi- tional wells, boreholes, and a ...

We present a new fast real time and quantitative gas analysis method by means of mass spectrometry (MS), which has approximately an order of magnitude faster sampling rate in comparison with a traditional gas chromatography. The method is presented and dis ...

Pairing light and heavy chains in monoclonal antibodies (mAbs) using top-down (TD) or middle-down (MD) mass spectrometry (MS) may complement the sequence information on single chains provided by high-throughput genomic sequencing and bottom-up proteomics, ...

Vegetables and water samples have been collected around the lake of Loumbila in Burkina Faso. Pesticides resi- dues in food commodities were analyzed using a modified QuEChERS extraction method prior analysis on GC-MS and UPLC-MS/MS of 31 pesticides. Maxim ...

The present thesis aimed at characterizing the extent of the pesticide contamination and resulting impacts on the environment and the human health in market garden-ing areas in Burkina Faso. Analytical procedures were developed and validated for multi-clas ...

Mass spectrometry (MS) is an essential detection tool in bioanalytical chemistry owing to its exceptional selectivity and sensitivity, paired with rapid analyte identification and quantification. In this thesis, two classical MS and a newly developed ioniz ...

The present study reports the photocatalytic degradation of aldehydes using TiO2 impregnated polyester (PES) and glass fiber (GFT)-TiO2 addressing the photocatalytic degradation aldehydes (air-solid interface). The PES-TiO2 optical absorption was determine ...

The work presented in this dissertation lies in the domains of image classification, object detection, and machine learning. Whether it is training image classifiers or object detectors, the learning phase consists in finding an optimal boundary between po ...

This paper proposes a minimalist modeling approach for characterizing pesticide concentrations in runoff from agricultural catchments across spatial scales. The model proposed is of an intermediate level of complexity between traditional chromatographic se ...
