  1. 1. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Christina Andersen; [2020]
    Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE

  2. 2. Near-Infrared Spectral Measurements and Multivariate Analysis for Predicting Glass Contamination of Boiler Fuel

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Olivia Winn; Kiran Thekkemadathil Sivaram; [2017]
    Keywords : NIRS; glass detection; food waste; biomass; PLS; SNV; Savitzky-Golay;

    Abstract : This degree project investigates how glass contamination in refuse-derived fuel for a fluidised bed boiler can be detected using near-infrared spectroscopy. It is motivated by the potential to reduce greenhouse gas emissions by replacing fossil fuels with refuse-derived fuel. READ MORE

  3. 3. Comparison between Calibrations of Fish Oil and AkoFeed Examined with Near-Infrared Light for Use in Animal Feed

    University essay from Lunds universitet/Tillämpad biokemi

    Author : Camilla Nilsson; [2016]
    Keywords : RMSEP; Validation; PLS; Calibration; NIR; SNV; Sow Feed; Fish oil; AkoFeed Standard; R2; KBK820; applied biochemistry; tillämpad biokemi; Technology and Engineering;

    Abstract : The aim with this master thesis was to investigate if a certain sow feed requires different calibrations in near-infrared analysis, due to if the sow feed have fish oil or AkoFeed as fat source. To investigate this, a basic sow feed mix was prepared and divided in 60 jars with 250 g in each. READ MORE

  4. 4. Design of an in-silico workflow to trace the spread of zoonotic bacteria using NGS data

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Adrien Janssens; [2015]
    Keywords : Salmonella enterica; next generation sequencing; genotyping; GATK; single nucleotide polymorphism; traceability; clustering;

    Abstract : Tracing the spread of foodborne illness to analyze and prevent future outbreaks has become a major subject of the food-producing industry and the national food agency these past decades, and one of the main worries of the veterinarian sector. Methods for comparing bacterial strains for this purpose have generally required substantial manual effort, and have provided insufficient information. READ MORE

  5. 5. Detection and Quantification of PCB insoil using GC/MS : - method development and education for users

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Elias Saba; [2013]
    Keywords : Transformative learning; GC; MS; PCB; teaching; pedagogics; detection; quantification; quadrupole MS; internal standard; chemical analysis; user manual; artefact; cognitivism; social constructivism.; Transformativ lärande; GC; MS; PCB; lärande; pedagogik; detektion; kvantifiering; kvadrupol MS; intern standard; kemisk analys; användamanual; artefakt; kognitivism; social konstruktivism.;

    Abstract : The aim of this paper is to document the development of a method for detectionand quantification of Polychlorinated biphenyls (PCB) in soil using GasChromatography (GC) connected to a Quadrupole Mass Spectrometer (MS) via aninternal standard (CB189). The method developed is performed in conjunction withthe information provided by the Swedish environmental agency (Svenskanaturvårdsverket, SNV) in regards to PCB limits for sensitive land usage.
