1. 1. Moisture Transport in PA6

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : Emanuel Markström; [2022]
   Keywords : Technology and Engineering;

   Abstract : Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. 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

4. 3. Understanding product build up at packaging material surface to address food waste

   University essay from Lunds universitet/Förpackningslogistik

   Author : Ashri Nugrahini; Sonam Lhamo; [2019]
   Keywords : Yoghurt; Packaging material; Build up; Yield stress; Gravimetric dip test; Agriculture and Food Sciences; Technology and Engineering;

   Abstract : Difficulty to empty the package is one of the main reason of food waste in yoghurt at consumer level with an estimated 5-10% of product residue being left on the packaging material. The phenomenon of product build up is explained by numerous hypothesis. However, these studies are empirical in nature. READ MORE

5. 4. Fine particle emissions from biomass cookstoves : Evaluation of a new laboratory setup and comparison of three appliances

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Natxo Garcìa Lòpez; [2017]
   Keywords : Particulate matter emissions; cookstoves; gravimetric measurements; soot and salt particles; SMPS.;

   Abstract : It is estimated that around three billion people globally rely on traditional usage of biomass to cover their daily energy needs, which causes health and social inequality problems and contributes to global warming. Thus, the study of particle emissions from cookstoves provides important information that can help improve global welfare. READ MORE

6. 5. Kinetics of Swelling Applied on Gelatine

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Victor Norgren; [2015]
   Keywords : fluid dynamic gauging FDG ; gravimetric measurements; pseudo-sigmoidal model PSM ; pseudo-second order model; Ofner; Robinson; Hofmeister; gelatine; swelling; food engineering; livsmedelsteknik; bio-polymers; anisotropic material; Arrhenius equation; physical chemistry; photography; pharmaceutics; Agriculture and Food Sciences;

   Abstract : This report is about the measurements of swelling gelatine films of different thickness and at different temperature. The research has been mainly focused on finding a suitable model. Results have shown that the new Pseudo-Sigmoidal Model (PSM) is superior to previous quasi-second order models such as the Robinson and Ofner model. READ MORE
