1. 1. Study of demolition processes for prestressed concrete bridges: Kalix bridge

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Lundin Hanna; [2022]
   Keywords : Kalix bridge; demolition methods; demolition process; FEM analysis; Kalixbron; rivningsmetoder; rivningsprocesser; FEM analys;

   Abstract : Bridges in Sweden are getting older and some of them are reaching their designed life span. With an older generation of bridges, the need for a good understanding of demolition processes increase. The Kalix bridge is planned to be demolished and will be used as a case study in this thesis.

3. 2. Petrography and Thermodynamic Modelling of Svecofennian Arsenic-bearing Metasupracrustal Rocks in the Arlanda Area, West-Central Fennoscandian Shield

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Klara Skoog; [2022]
   Keywords : Bergslagen; Svecokarelian orogeny; metamorphism; arsenic; optical microscopy; electron microprobe; thermodynamic modelling; Bergslagen; Svecokarelska orogenesen; metamorfos; arsenik; optisk mikroskopering; elektron mikrosond; termodynamisk modellering;

   Abstract : The Arlanda area is a construction intensive area facing problems with risk of leaching of arsenic (As) from the bedrock to surface- and groundwater. Construction projects in the area have had problems with high levels of As in the bedrock and the risk of leaching increases through processing of aggregates and blasting of the bedrock. READ MORE

4. 3. Development of a Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility

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

   Author : Josephine Lindsey-Clark; [2021]
   Keywords : Neutron Activation Analysis; NAA; European Spallation Source; ESS; Lund Ion Beam Analysis Facility; LIBAF; Gamma-Ray Spectra; Physics and Astronomy;

   Abstract : This report outlines the first stages of the development of the Neutron Activation Analysis station at the Lund Ion Beam Analysis Facility in the Division of Nuclear Physics, Lund University. The motivation for this project is to use the Neutron Activation Analysis detection technique for environmental monitoring around the European Spallation Source, soon to come into operation.

5. 4. Tribological characterisation of additively manufactured hot forming steels

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Anna Vikhareva; [2020]
   Keywords : High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

   Abstract : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. READ MORE

6. 5. Increased leaching of metals as a result of foundation work

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Emmy Mattisson; [2018]
   Keywords : Principal components analysis; Modified double mass analysis; Geochemistry; Sulphide bedrock; Remediation methods; Surface water pollution;

   Abstract : Heavy metal contamination in the environment is a global issue that is likely to increase in the future. This report investigates a construction area in which increased concentrations of the heavy metals cadmium, cobalt, copper, nickel and zinc and a decreased pH-value has been observed in the surface water recipient.
