Kan den fungera som en källa till naturvetenskaplig kunskap?
… in the sediment and the relationship between the amount of P and sediment particle size were investigated in a constructed wetland southwest of Linköping. Furthermore, the possible correlation between clay content in the sediment and distance from the inlet was investigated …
… was also tested in a road machine made for testing of asphalt paving. The particles created in the machine were analysed in the same manner as the cryogrinded asphalt materials. The asphalt materials were leached by water during 24 hours. The leachates were extracted with …
En användningscentrerad utvecklingsmetod
The company GEMS PET Systems produces cyclotrons which is a type of particle accelerator. The cyclotrons create log files that are analyzed by the company’s employees for different purposes like troubleshooting or installation. The purpose of the project is to with a …
… together with a high argon flow during vacuum degassing seems todissolve particles from the refractory which later on get trapped inside the inclusions.The floatation for two heats has been studied where a short floatation seems to give a higheramount of inclusions in casted …
Some observations on the impact of clothing systems on the concentration of airborne bacteria-carrying particles during surgery
Detta examensarbete har utforts i omradet skyddsventilation vid avdelningen for installationsteknik, Kungliga Tekniska Hogskolan. Examensarbetet omfattar 30 kurspoang och ar den avslutande delen i civilingenjorsutbildningen. Fragestallningar diskuteras om den inverkan kladsystem …
… bleeding increases when the level of platelets falls below a thrombocyte particle concentration threshold value of 50 x 109/L. In those cases a platelet transfusion might be compulsory. Ongoing research tries to improve the quality of the platelets and to increase the safety of …
Jämförelse av partikelnivåer centralt och perifert på operationssal
Flertalet studier har påvisat ett samband mellan koncentrationen av partiklar ? 10µm i luftföroreningar och cardiovaskulär- och pulmonell morbiditet och mortalitet. Vid resektion, koagulering/bränning med diatermipenna under operationer alstras rök. Denna rök innehåller bland …
… characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the …
… already occurred. Furthermore, try also to comminute the material (reduce the particle size) at the plant and as close in time to combustion as possible.

Anlagda våtmarker i avrinningsområden från jordbruksmarker mottar ofta vatten med höga halter av partikelbunden fosfor. Den viktigaste processen för avskiljning av inkommande partikelbunden fosfor är sedimentation. Resuspension är en process som motverkar netto-sedimentationen …
Fosfor (P) är ofta det begränsande ämnet i akvatiska system och kan i höga mängder bidra till övergödning i sjöar och hav. För att minska tillförseln av partikelbunden fosfor som läcker från jordbruksmark kan våtmarker anläggas i avrinningsområdet. För en effektiv avskiljning är …
