1. 21. The influence of particle size distribution on bio-coal gasification rate as related to packed beds of particles

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Markus Bäckebo; [2020]
   Keywords : Bio-coal; Particle size distributions; Reaction rate; Gasification;

   Abstract : This thesis is a part of a collaboration between Höganäs AB and Luleå University of Technology, aiming at replacing fossil process coal with bio-coal in their sponge iron process. The difference in gasification reactivity, i.e. READ MORE

3. 22. Decreasing organic nitrogen concentrations in European water bodies - links to organic carbon trends and land cover

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alexis Cazorla; [2020]
   Keywords : geography; GIS; physical geography; organic nitrogen; organic carbon; land cover; eutrophication; Europe; Earth and Environmental Sciences;

   Abstract : European rivers experience increasing concentrations of total organic carbon (TOC) from terrestrial sources due to factors involving changes in land use, climate and soil acidity. However, low interest is given to the evolution of total organic nitrogen (TON) concentrations in surface waters, the links with TOC concentrations and the influence of the surrounding land cover on nutrient inputs.

4. 23. Perceived Psychological Safety and Causal Attributions of Errors of Working Students: The Mediating Role of Error Orientation

   University essay from Linnéuniversitetet/Institutionen för psykologi (PSY)

   Author : Leonie Kauke; Laura Noack; [2020]
   Keywords : perceived psychological safety; error orientation; causal attributions of errors; working students;

   Abstract : Given that causal attributions of errors contain different motivational and behavioral implications for learning from errors, it is highly relevant for organizations to thoroughly understand the factors that promote functional attributions. This study set out to investigate whether perceived psychological safety is an antecedent of functional and dysfunctional causal attributions of errors and whether this association is mediated by error orientation.

5. 24. 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

6. 25. CONSTRUCTION EQUIPMENT FUEL CONSUMPTION DURING IDLING : Characterization using multivariate data analysis at Volvo CE

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

   Author : Mujtaba Hassani; [2020]
   Keywords : Idling condition; environmental effect; diesel fuel; machine learning; multivariate data analysis; partial least square regression; support vector machine regression; principal component analysis; principal component regression; correlation coefficient matrix; artificial neural network; exhaust emission reduction techniques; global warming; emission regulation; CO2 estimation techniques; Gaussian process regression;

   Abstract : Human activities have increased the concentration of CO2 into the atmosphere, thus it has caused global warming. Construction equipment are semi-stationary machines and spend at least 30% of its life time during idling. The majority of the construction equipment is diesel powered and emits toxic emission into the environment. READ MORE
