  2. 11. Modelling and simulation of building components : thermal interaction between multilayer wall and hydronic radiator

    Author : Christian Brembilla; Thomas Olofsson; Per Sahlin; Persson Leif; Annika Moström; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; systemanalys; Systems Analysis; engineering science with specialization in microsystems technology; teknisk fysik med inriktningen mikrosystemteknik;

    Abstract : Background and Scope: The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. READ MORE

  4. 12. Production in a State of Abundance : Valuation and Practice in the Swedish Meat Supply Chain

    Author : Jonas Bååth; Patrik Aspers; Tora Holmberg; Turo-Kimmo Lehtonen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; abundance; production; valuation; Swedish meat industry; supply chain; post-scarcity society; economic sociology; food studies; agriculture; grocery retail; pragmatism; practice theory; ethnography; Sociologi; Sociology;

    Abstract : This thesis is a sociological contribution to the study of abundance. It discusses the case of Swedish meat producers and how they persist in producing pork and beef despite a lack of demand and competitive disadvantages compared with foreign suppliers. READ MORE

  5. 13. Cost allocation methods in cooperative transportation planning

    Author : Joen Dahlberg; Stefan Engevall; Maud Göthe-Lundgren; Jenny Karlsson; Athanasios Migdalas; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Transportation, together with transportation planning for goods, provides good conditions for economic growth and is a natural part of modern society. However, transportation has negative side effects, including emissions and traffic congestion. READ MORE

  6. 14. Organic Phosphorus Compounds in Aquatic Sediments : Towards Molecular Identification with Mass Spectrometry

    Author : Heidi De Brabandere; Monica Waldebäck; Emil Rydin; Per J. R. Sjöberg; Rolf Danielsson; William T. Cooper; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; electrospray ionisation; mass spectrometry; liquid chromatography; organic phosphorus; aquatic sediment; eutrophication; sample preparation; extraction; Analytical chemistry; Analytisk kemi;

    Abstract : Phosphorus (P) regulates trophic status in most aquatic systems. However, only bioavailable P contributes to primary production. In most lakes and shallow seas, mineralisation of sediment P into its bioavailable form and its release to the water column is important for maintaining primary production. READ MORE

  7. 15. Toward Realistic Failure Evaluations for Concrete Buttress Dams

    Author : Jonas Enzell; Anders Ansell; Erik Nordström; Andreas Sjölander; Richard Malm; Leif Lia; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; buttress dams; stability analysis; dam failure behavior; physical model tests; FEM; betongdammar; lamelldammar; stabilitetsanalys; dammbrott; fysiska modellförsök; FEM; Betongbyggnad; Concrete Structures;

    Abstract : Concrete dams, complex structures supporting massive loads, have traditionally been assessed using simplified 2D analytical stability analyses based on the rigid body assumption. Previous studies have shown that 3D behavior, such as the interaction between the monoliths and the valley's geology, can greatly impact the load-bearing capacity of gravity dams but remains largely unexplored in buttress dams.
