  1. 1. Finite element analysis of temperature in hardening concrete using isothermal calorimetric data

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : John Mac; [2017]
    Keywords : isoconversion; isothermal calorimetry; thermal analysis; finite element method; numerical simulation; Technology and Engineering;

    Abstract : The produced heat in hardening concrete is of special importance to consider as the temperature rise within a large concrete structure can become such high that the structure may experience thermal cracking. With use of a simulation program that is based on the finite element method, the temperatures within the structure can be estimated to predict possible crack development. READ MORE

  2. 2. Watering down justice : energy justice in the Inga dams case in the DRC

    University essay from Lunds universitet/LUCSUS

    Author : Ruth Krüger; [2017]
    Keywords : hydroelectric dams; energy justice; sustainability science; Democratic Republic of Congo; post-colonial context; Social Sciences;

    Abstract : The focus of this thesis is energy justice and sustainability science, and the argument is based on a case study of the Inga dams. Substantial further development of hydropower is planned at the Inga dams, located on the Congo River in the Democratic Republic of Congo. READ MORE

  3. 3. Storm water treatment in a multi-step system compared to a single-step system

    University essay from SLU/Dept. of Soil and Environment

    Author : Maria Schoeps; [2017]
    Keywords : storm water; storm water treatment; open storm water system; storm water dams; multi-step treatment; StormTac; pollutant load;

    Abstract : Urban areas are expanding at an increasing pace around the world as well as surfaces with impervious layers, such as streets and rooftops. Precipitation, melt water and water from human activities, which temporarily flow on these surfaces are defined as storm water. READ MORE

  4. 4. Numerical analyses of concrete buttress dams to design dam monitoring

    University essay from KTH/Betongbyggnad

    Author : Daniel Svensen; [2016]
    Keywords : Concrete; buttress dams; thermal effects; finite element analysis; instrumentation; alarm values; alert values; Betong; lamelldammar; termiska effekter; finit element analys; intstrumentering; larmvärden;

    Abstract : Old concrete buttress dams are sensitive to cracking if exposed to large temperature variations. The cracks can make dams sensitive to failure, depending on the size and location of the cracks. These problems can be overcome by lowering the temperature variations and stabilizing the dams.

  5. 5. Riparian vegetation responses to hydropeaking : Experimental study on germination and performance of plants along rivers regulated by hydropower dams in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Emelie Fredriksson; [2016]
    Keywords : Hydropeaking; riparian vegetation; germination; survival; performance; phytometer; restoration; mitigation;

    Abstract : Riparian vegetation is one of the most complex and abundant ecosystems in the world and it provides important ecosystem services. These services are affected by electricity production from hydropower dams. Hydropower accounts for 16% of the global electricity production and almost 50% in Sweden. READ MORE
