1. 6. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

   University essay from SLU/Dept. of Soil and Environment

   Author : Honorine Uwera; [2020]
   Keywords : turbidity; suspended sediments; dissolved organic matter; optical measurements;

   Abstract : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). READ MORE

3. 7. Aerosol Input and Snow Accumulation Rates on the Northern Greenland Ice Sheet : Reconstructed by means of Continuous Flow Analysis (CFA) of 6 shallow firn cores

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Patrick Stephan Zens; [2018]
   Keywords : continuous flow analysis; Greenland; shallow firn core; aerosol; snow accumulation; glaciochemistry; kontinuerlig flödesanalys; Grönland; grunda firnkärnor; aerosol; snöackumulering; glaciokemi;

   Abstract : Ice, firn and snow cores from the Greenland ice sheet offer a unique opportunity to reconstruct past climate conditions. These can be analyzed with continuous flow analysis (CFA) in order to acquire proxy information about ancient atmospheric aerosol concentrations, snow accumulation rates or temperature variations, atmospheric composition, solar activity as well as volcanism and biological activity.

4. 8. Critical Assessment of the Mineralogical Collections at Uppsala University using Raman Spectroscopy

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Yuliya Zhuk; [2017]
   Keywords : Raman spectroscopy; gemmology; geology; mineralogy; Mineralogical Collectio; Ramanspektroskopi; gemologi; geologi; mineralogi; mineralogisk samling;

   Abstract : The technique of Raman spectroscopy was applied in order to identify and characterize the number of minerals in the mineralogical collection at the Department of Earth Sciences. The collection was broadened with five rare carbonates borrowed from the collection of the Swedish Museum of Natural History in Stockholm. READ MORE

5. 9. Reconstructing the historic input of mercury in Lake Ekoln : A long-term (millennia) perspective derived from a sediment core

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Clara Rojas Rodríguez; [2015]
   Keywords : mercury; sediments; aquatic ecosystem; Lake Ekoln.;

   Abstract : Anthropogenic activities are often considered to be the main sources of mercury (Hg) found in aquatic systems. The aim of this study was to reconstruct the historic input of Hg to a large lake (Lake Ekoln) situated downstream the City of Uppsala using a dated sediment core. READ MORE

6. 10. Transient State Monitoring and Fluorescence Correlation Spectroscopy of Flavin Adenine Dinucleotide

   University essay from KTH/Experimentell biomolekylär fysik; KTH/Skolan för teknik och hälsa (STH)

   Author : Liv Egnell; [2014]
   Keywords : Transient State Monitoring; Fluorescence Correlation Spectroscopy; Flavin Adenine Dinucleotide; FCS; TRAST; FAD;

   Abstract : Many human diseases including cancer have been associated with altered cellular metabolism and a changed oxygen consumption in cells. Fluorophores are sensitive to their local environment due to their long life times in transient dark states. READ MORE
