… the flavour intensity between selected wheat bran samples and determine the particle size of all bran samples. The results in this thesis showed that the total dietary fibre (TDF) content decreased with increasing roasting temperature and the uncooked bran samples had a higher …
… construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already …
kortast, snabbasteller hälsosammast : En försöksmodell i GIS för ruttoptimering och beräknad inhalation av luftföroreningar för cykelrutter
… that estimates theinhaled dose of air pollution for cyclists based on relative particle concentration in differenttransportation micro-environments. The method used is a least-cost path approach,calculating three different routes; shortest, fastest and least dose for four …
The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace
… experiments with ore concentrates were performed on a laboratory scale. Simple particle size measurements were performed as well. It could be ascertained that raising the temperature increased the cupellation of arsenic and that magnesium carriers bind less arsenic than calcium …
Denna rapport ar resultatet av ett examensarbete som har utforts vid institutionen for informationsoch kommunikationsteknik, Kungliga Tekniska Hogskolan (KTH), och omfattar 15 hp. Rapporten presenterar ett arbete dar examensarbetarna har utvecklat en terrang med hojdskillnader …
Strömmars betydelse för lokalisering av odlingslokaler och utformning av kontrollprogram i kustområden
… study was made to evaluate how current measurementscould help to determine how particles from fish farms are dispersed. During sixweeks of the summer 2012, two different current measurements were conducted.One of them consisted of measurements each fifth minute at 5 m and 15 m …
… marine animals ” mistaking them for plankton ” or via prey. When ingested, the particles affect the animals due to their physical properties, their chemical properties (the plastic polymer itself and additives) and persistent organic pollutants (POPs) gathered on their surface …
… PE and PP can prevent the formation of billions and trillions of microplastic particles per year respectively if the material is collected instead of remaining in the ocean, where PP fragments significantly faster than PE. Furthermore, life cycle assessments show that material …
A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to …
… sylvestis). Traces of human activity are subtle but the occurrence of charred particles, increased influence of Betula and the presence of light demanding species, it cannot be ruled out that the area was used temporarily by people already c.7500 BC.
… of secondarily minerals as well as adsorption to iron, manganese and aluminium particles. The groundwater in the pipes close to waste rock and slag most certainly consists of surface water that runs off from the heaps on top of the hill. This is demonstrated by the high metal …
Modellanalys av vattenflöde till Hörviks vattentäkt
… model, simulating the water flow, was created. The model was used to trace the particles flowing to the well in order to find the most likely source. GMS Modflow and Modpath were used to create the model. The validation of the model shows that the model is good enough to be used …
… in a larger study that assessed the relationship of amount and type of inhaled particles in equine stable air on indices of respiratory inflammation in horses and people. During this study an unanticipated and marked elevation in lung eosinophils was detected in a number of the …
… lost from the arable land due to water erosion. Both phosphorus attached to particles and dissolved phosphorus (mainly phosphate) are transported away with drainage-water and surface runoff. Good soil structure is important in minimizing these losses. In this study, soils from …
… temperatures, and the drying depended on how hard the water was bond to the particles of the substrate. The energy removed with aeration from the containers became higher as temperature rose; however, the fastest drying was obtained at higher temperatures. The amount of energy …
