1. 1. A destructive host-shift : a comparative review of resistance mechanisms in the novel and original hosts of Varroa destructor

   University essay from SLU/Dept. of Ecology

   Author : Elin Sjögren Englund; [2022]
   Keywords : Varroa destructor; Apis cerana; Apis mellifera; host-shift;

   Abstract : Apiculture has a major antagonist in Varroa destructor, the ectoparasitic mite that has become the most prominent driver of colony losses for the European honey bee, Apis mellifera. This was not always the case, as V. destructor is native to Asia and originally only infested the Asian honey bee, Apis cerana. As these two species have co-evolved, A. READ MORE

3. 2. 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
