Quantification of large steam bubble oscillations and chugging using image analysis
(Lappeenranta-Lahti University of Technology LUT, 2019-11-01)
The pressure suppression pool of a boiling water reactor as a safety system has vital importance from the nuclear reactor safety point of view. If a loss-of-coolant accident occurs, a large amount of steam is pushed through ...
Supercritical CO2 Numerical Modelling and Turbomachinery Design
(Lappeenranta-Lahti University of Technology LUT, 2019-04-16)
Supercritical CO2 Brayton cycles have attracted significant attention in recent years on the basis that they can achieve higher thermal efficiency at relatively lower turbine inlet temperature in comparison to conventional ...
Towards a sustainable valorisation of spilled oil by establishing a green chemistry between a surface active moiety of chitosan and oils
(Lappeenranta-Lahti University of Technology LUT, 2019-08-15)
This thesis presents fabrication of sustainable surfactants from bio-polymer and demonstrates their performance in dispersion of spilled oil with different quality of water and climatic conditions, to provide a sustainable ...
Agent-based modelling for epidemiological applications
(Lappeenranta-Lahti University of Technology LUT, 2019-03-29)
Malaria is an infectious disease induced by protozoan parasite called Plasmodium and transmitted by Anopheles mosquitoes which still imposes a health threat to virtually half of the human populace and causes severe mortality, ...
The board of directors as a part of family business governance – multilevel participation and board development
(Lappeenranta University of Technology, 2014-11-07)
In this study, I examine the board of directors as a part of family business governance. Both
boards and governance have increased their attractiveness as a research topic lately. Research
on boards has concentrated ...
Agent-Based Modeling as Part of Biomass Supply System Research
(Lappeenranta-Lahti University of Technology LUT, 2019-06-14)
Interest in the use of agent-based modeling (ABM) for studying biomass supply systems has increased because of its flexible and cost-efficient nature. While ABM has been around for a long time, recent developments in ...
Catalytic direct synthesis of hydrogen peroxide in a novel microstructured reactor
(Lappeenranta University of Technology, 2014-12-02)
The direct synthesis from hydrogen and oxygen is a green alternative for production of
hydrogen peroxide. However, this process suffers from two challenges. Firstly, mixtures of
hydrogen and oxygen are explosive over a ...
Impacts of capacity remunerative mechanisms on cross-border trade
(Lappeenranta University of Technology, 2015-09-21)
The European ambitious targets to increase the share of renewable generation pose a challenge
to the generation adequacy. Many European member states are concerned that energy-only
markets alone might not be able to ...
Actors in Sustainability Transitions
(Lappeenranta-Lahti University of Technology LUT, 2019-04-26)
The world is experiencing serious sustainability challenges, such as climate change and the loss of biodiversity. To respond to these sustainability challenges, there is a need for societies throughout the world to make ...
Modified nano- and microcellulose based adsorption materials in water treatment
(Lappeenranta University of Technology, 2014-11-07)
In recent decades, industrial activity growth and increasing water usage worldwide have led to the release of various pollutants, such as toxic heavy metals and nutrients, into the aquatic environment. Modified nanocellulose ...
