Net Climate Effects of Moose Browsing in Early Successional Boreal Forests by Integrating Carbon and Albedo Dynamics
(Peer reviewed; Journal article, 2023)Moose (Alces alces) is a large herbivore that can mediate boreal forest regeneration after timber harvest through selective browsing of tree species. Despite increasing evidence of moose browsing influence on tree growth ... -
NEW AND ENERGY EFFICIENT DRYING FOR PROTEIN MIXTURES: Treatments and drying conditions effects on product quality and kinetics
(Master thesis, 2012)Drying is an essential process applied in most industry to remove moisture and extend the shelf life of final dried products without refrigeration. The challenges are to develop technologies to minimize the impact to ... -
A new approach of optimal appliance scheduling for peak load reduction of an off-grid residential building
(Peer reviewed; Journal article, 2022)Demand for electricity, due to the fast growth in urbanization and industrialization, is on the rapid rise. Load shift is a basic method for demand side management (DSM) that can be used by the central controller in buildings ... -
A new cold cooling system using krypton for the future upgrade of the LHC after the Long Shutdown 4 (LS4)
(Peer reviewed; Journal article, 2024)Future silicon detectors for High Energy Physics Experiments will require operation at lower temperatures to cope with radiation damage of the sensors and consequent increase of the dark current, beyond the limit of the ... -
A new data mining strategy for performance evaluation of a shared energy recovery system integrated with data centres and district heating networks
(Journal article; Peer reviewed, 2023)This study presents a new data mining strategy to discover the performance and operational patterns of a shared energy recovery (SER) system with a data centre and a district heating network. Multidimensional clustering ... -
A new design of catalytic tube reactor for hydrogen production from ethanol steam reforming.
(Peer reviewed; Journal article, 2020)A new design of the catalytic tube system with a crossflow configuration, featured by low catalyst usage and cost, is developed using computational fluid dynamics (CFD). Meanwhile, the kinetics of ethanol steam reforming ... -
New dose-response model and SARS-CoV-2 quanta emission rates for calculating the long-range airborne infection risk
(Peer reviewed; Journal article, 2022)Predictive models for airborne infection risk have been extensively used during the pandemic, but there is yet still no consensus on a common approach, which may create misinterpretation of results among public health ... -
New indicator of habitat functionality reveals high risk of underestimating trade-offs among sustainable development goals: The case of wild reindeer and hydropower
(Peer reviewed; Journal article, 2023)Although biodiversity is crucial for Sustainable Development Goals (SDGs), following the current trajectory, we risk failing SDG 15. Using a new indicator quantifying the loss of functional habitat (habitat that is ... -
New Insights into Computational Fluid Dynamic Modeling of the Resistivity and Overpotential in Reverse Electrodialysis
(Journal article; Peer reviewed, 2018)The resulting electrical potential of a reverse electrodialysis is reduced both due to ohmic and non-ohmic resistances. The non-ohmic resistance is mainly controlled by concentration polarization which is a considerable ... -
