  1. 1. Apparent density for water atomized low-carbon steel powder

    University essay from KTH/Materialvetenskap

    Author : Simon Lindström; [2023]
    Keywords : ;

    Abstract : Carbon content does not affect the apparent density for water atomized iron powder monotonically. At low carbon content, around 0.1 wt %, apparent density is higher than a similar powder with 0.3 wt % carbon. READ MORE

  3. 2. Influence of Surface Carbon Content on the Wear of Threaded Connections in Rock Drilling Steels

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

    Author : Andreas Hälsing; [2023]
    Keywords : carbon content; wear performance; carburized steel; dry contact interface; threaded connections; drill rods; samples; shot peening; production process; twin-disc wear tester; RPM; operating conditions; wear rate; surface topography; hardness; optical analysis; light optical microscopy; scanning electron microscopy; surface carbon content; microstructural changes; frictional heat; contact pressure; wear mechanisms; plastic deformation; adhesive scratching; material removal; delamination;

    Abstract : This thesis work was conducted at Luleå University of Technology in collaboration with Sandvik Rock Tools. The aim of the work was to determine the influence of carbon content on the wear performance in carburized steel in the dry contact interface of threaded connections between drill rods. READ MORE

  4. 3. Beyond the Surface: A Comprehensive Look into Swedish Companies' Scope 3 Greenhouse Gas Emission Assessments

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Livia Magnusson Rauf; [2023]
    Keywords : Emission factor; Greenhouse gas assessments; Scope 3 emissions; Sustainable Development; Sustainability report; Value chain.;

    Abstract : As the world grapples with the increasingly dire effects of climate change, companies are under more pressure than ever before to not just report on their environmental impact, but to actively work towards sustainability. Carbon accounting has emerged as a crucial aspect of this reporting, and the concept of Scope 3 emissions, introduced by the Greenhouse Gas Protocol a decade ago, is now a vital tool for assessing a company's environmental footprint.

  5. 4. ARCTIC PLANT COMMUNITIES RISE WITH TEMPERATURE Plant functional traits as a tool to predict global climate change

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Helena Sundell; [2022-07-06]
    Keywords : Arctic warming; plant functional traits; Community Weighted Mean; vegetational changes; global climate change;

    Abstract : Global warming occurs at a rate at least three-fold in the arctic regions compared to the rest of the world. Here, plant community functional traits were assessed in response to experimental warming in three arctic areas of Fennoscandia (Latnajajure, Abisko and Kilpisjärvi). READ MORE

  6. 5. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Simon Fridolfsson; [2022]
    Keywords : HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Abstract : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. READ MORE
