16. Chemical Stabilization of Arsenic in Contaminated Soil under Low Redox Conditions
Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Remediation techniques for arsenic contaminated soil have previously focused mostly on the surface soil layers where aerobic conditions are prevalent. In this master thesis, chemical stabilization by adding zero-valent iron (Fe(0)) and calcium oxide (CaO) to an arsenic-contaminated soil under low redox conditions have been studied through up-flow percolation tests.

17. Material modeling in Sheet Metal Forming Simulations : Quality comparison between comonly used material models
Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknikSammanfattning : In today's automotive industries, many different simulation programs are used to optimize parts before they come into production. This has created a market for complex material models to get the best possible approximation of reality in the simulation environment. LÄS MER
18. Utveckling av slangrulle för effektivare produktion
Master-uppsats, Mälardalens högskola/Akademin för innovation, design och teknikSammanfattning : Detta är ett examensarbete på civilingenjörsnivå mot produkt och processutveckling hos Mälardalens högskola, på 30 högskolepoäng, motsvarande 20 veckor. Manovi Varberg AB har under eget varumärke en elektriskt driven slangrulle för industriellt bruk. Designen är gammal och försäljningen bedrivs inte aktivt. LÄS MER
19. The comparison of automatic and manual loading in an underground mining environment
M1-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : Mine automation has been in development since the 1980s and began to be implemented in the 1990s with the biggest drivers being safety, reduced maintenance and increased productivity. Automation is used in many different mining methods performing a variety of tasks. LÄS MER
20. Spatiotemporal reconstructions of black carbon, organic matter and heavy metals in coastal records of south-west Sweden
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : This study presents reconstructions of black carbon (BC), including spheroidal and amorphous carbonaceous particles (SCP and ACP), organic matter (OM; total organic carbon, TOC; total nitrogen, TN; total sulfur, TS), and heavy metals (Fe, Zn, Pb, Cu, As and Hg) in coastal sediments off the south-west coast of Sweden. Sediment records from eight stations along a north-south transect off the south-west of Sweden were retrieved. LÄS MER
