  1. 1. Sköldlöss i orkidéodling : biologi, skadebild, förekomst och bekämpningsmetoder

    Kandidat-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Oscar Björn; [2018]
    Nyckelord :orkidéer; sköldlöss; diaspis; coccus; pseudococcus; planococcus; diaspididae; pseudococcidae; coccidae; coccoidea;

    Sammanfattning : Sköldlöss kan angripa en lång rad kulturer, däribland familjen Orchidaceae, orkidéerna. Denna består av 25 000 arter och står för omkring 10% av de blommande växterna. Samtliga orkidéarter riskerar att bli eller är utrotningshotade. LÄS MER

  3. 3. Värmeöverföring mellan två zoner i en bubblande fluidiserad bädd

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Författare :Christian Stigsson; [2018]
    Nyckelord :Heat transfer; fluidized beds; multi-staging; Eulerian-Eulerian two-fluid; Technology and Engineering;

    Sammanfattning : In this Master's thesis, the heat transfer between two zones in a bubbling fluidized bed and the resultant temperature field were examined using a laminar Eulerian-Eulerian two-fluid model in computational fluid dynamics. The purpose was to estimate the thermal potential to multi-stage a combined heat and power boiler by integration therein of a communicating gasification reactor, which utilizes heat from the combustion, and to analyze how different construction parameters influence the homogeneity of the gas temperature field.
