1. 36. Novel approaches for monitoring effects of steel corrosion in reinforced concrete

   Författare :Andreas Alhede; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reinforced Concrete; Neutron and X-ray Computed Tomography; Corrosion; Distributed Optical Strain Sensing;

   Sammanfattning : Corrosion of steel reinforcement is a common deterioration mechanism in reinforced concrete structures. This deterioration impacts the safety of the structure and may require extensive repair and maintenance work. There is currently no method available for accurately measuring internal corrosion damage non-destructively. LÄS MER

3. 37. Nitrate in foodstuffs : analytical standardisation and monitoring and control in leafy vegetables

   Författare :Leonardo Merino; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : The potential harm to human health and the environment of compounds derived from nitrate is an issue that occasionally awakens media and public concern. Recent studies provide a new understanding of the role of nitrate and nitrite in our body and motivate revision of the long-held view that nitrate poses a health risk. LÄS MER

4. 38. Molecular Trees for Collecting Sunshine -Monitoring and Controlling Energy Transfer in Dendrimers

   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetiska och optiska ; supraledare; magnetisk resonans; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; supraconductors; magnetic resonance; relaxation; spectroscopy; Condensed matter:electronic structure; electrical; magnetic and optical properties; Kemi; Chemistry; Femtosecond transient absorption; Os-Ru metal ligand complexes; Cu-porphyrin-appended dendrimers; Zn-porphyrin-appended dendrimers; Annihilation; Energy transfer; Solar energy conversion; Artificial photosynthesis; Antenna systems; spektroskopi; Physical chemistry; Fysikalisk kemi; Photochemistry; Fotokemi; Femtosecond fluorescence anisotropy;

   Sammanfattning : A continuing use of fossil fuels will accelerate global warning and result in severe consequences for the environment and thereby also us. Development of alternative, sustainable and environmentally friendly energy sources is therefore crucial. One approach is to create an artificial photosynthetic system that converts sunshine into fuel (e.g. LÄS MER

5. 39. Microextraction for usage in environmental monitoring and modelling of nitroaromatic compounds and haloanisoles

   Författare :Sofie Jönsson; Bert van Bavel; Tomas Öberg; Örebro universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PCA; PLS; QSPR; SPME; MEPS; nitroaromatic compounds; TCA; TBA; Chemistry; Kemi; Kemi; Chemistry;

   Sammanfattning : Processes in the environment are often complex and the description and prediction of the behaviour of environmental pollutants requires sophisticated methodology including multidimensional technology. Multivariate statistical methods including principal component analysis (PCA) and partial least squares projection to latent structures (PLS) were used to characterise several nitroaromatic compounds according to a large number of chemical and physical properties.

7. 40. On methods for estimating oceanic flow

   Författare :Jenny A. U. Nilsson; Peter Lundberg; Peter Sigray; Bert Rudels; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean monitoring techniques; Barotropic flow; Baroclinic flow; Hydraulic theory; Baltic Sea; Bahía de Concepción; Oceanography; Oceanografi; Oceanography; oceanografi;

   Sammanfattning : The aim of this thesis was to estimate and possibly quantify ocean flow by utilizing conventional and novel observational methods as well as model results. Motionally induced voltages, from a cable-based observational system in the Baltic Sea, were analysed to determine their utility for ocean monitoring. LÄS MER
