1. 1. Automated Control System for Dust Concentration Measurements Using European Standard Reference Method

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Gustav Marstorp; [2021]
   Keywords : Dust concentration measurements; Particle concentration; Isokinetic deviation; PID-controller; EU standard 13284-1:2017; Stoftmätning; Partikelkoncentration; PID-regulator; Isokinetisk avvikelse; EU standard 13284-1:2017;

   Abstract : Most companies that have any type of combustion or other pollution process via emission to air needs to measure their emissions to ensure they are within legal boundaries. Among the different types of pollution measurements, one of the most common is dust concentration, also known as particle concentration. READ MORE

3. 2. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Dana Lüdemann; [2020]
   Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

   Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

4. 3. Atmospheric Particles in Kermanshah, Iran

   University essay from Lunds universitet/Atomfysik; Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Rebecka Häggström; [2017]
   Keywords : aerosols; aerosol technology; SMPS; soot concentrations; dust; Iran; Kermanshah; PSAP; airborne particles; Technology and Engineering; Physics and Astronomy; Earth and Environmental Sciences;

   Abstract : No measurements of airborne particles have been done in Iran previously. Starting characterization of aerosol particles in a completely new geographical area, a suitable and important measurement parameter is the aerosol particle number size distribution. This can be used to indirectly infer climate- and health effects of the particles. READ MORE

5. 4. The Metal Content in Airborne Particles in Landskrona

   University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Wouter Prosper; [2017]
   Keywords : Earth and Environmental Sciences;

   Abstract : Landskrona has for a long time had problems with high concentrations of Pb and other heavy metals in the air. Measurements investigating the content of airborne particles have been performed in 1977, 1988, 2003 and 2008 and show an influence from heavy industries, traffic in town and transboundary pollution.

6. 5. Rörflen som strömedel i djupströbäddar för nötkreatur

   University essay from SLU/Dept. of Biosystems and Technology (from 130101)

   Author : Linnéa Holmström; [2014]
   Keywords : rörflen; strömedel; djupströbädd; damm; uppsugningsförmåga; ströåtgång;

   Abstract : På grund av de blöta höstarna de senaste åren har priset på halm stigit. Intresset har därmed ökat för att börja odla och använda energigräset rörflen som alternativt strömedel. Rörflen slås sent på hösten eller tidigt på våren för att sedan balas i slutet på april, eller i början på maj. READ MORE
