  1. 1. Trädplantering i den hårdgjorda staden : utmaningar och lösningsalternativ

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Ingela Carlgren; [2024]
    Keywords : gatuträd; urbana träd; trädplantering; gatumiljö; urban jord; kompaktering; skelettjord; makadamsubstrat; rotceller; suspended pavement;

    Abstract : Träd är viktiga delar av våra städer. De bidrar med många ekosystemtjänster, som klimatreglering, dagvattenhantering och positiva hälsoeffekter. De är också viktiga identitetsskapande element. READ MORE

  3. 2. Faded Glory : Cultural exchange between warrior groups in the Vendel Period as reflected in armor from Vendel and Valsgärde

    University essay from Uppsala universitet/Institutionen för arkeologi och antik historia

    Author : Julian Blaine; [2024]
    Keywords : Vendel Period; warfare; armor; cultural exchange; Vendel; Valsgärde; Black Sea; Vendeltid; krig; rustning; kulturellt utbyte; Vendel; Valsgärde; Svarta havet;

    Abstract : This thesis analyzes and documents the splint armor material from Valsgärde 8 and Vendel I,X, and XI. This armor is then contextualized in the warrior institutions, weapon-systems, and fighting techniques of warbands from Central Sweden. READ MORE

  4. 3. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktor Lange; [2023]
    Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

  5. 4. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Chun Hei Ho; [2023]
    Keywords : Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Abstract : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. READ MORE

  6. 5. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE
