Genetic evidence of a northward range expansion in the eastern Bering Sea stock of Pacific cod

open access: yesEvolutionary Applications, 2019
Poleward species range shifts have been predicted to result from climate change, and many observations have confirmed such movement. Poleward shifts may represent a homogeneous shift in distribution, seasonal northward movement of specific populations ...

Numerical investigation of a new LH2 centrifugal pump concept used in space propulsion [PDF]

open access: yesINCAS Bulletin, 2018
The present study deals with efficiency increase of a centrifugal pump for liquid rocket propulsion by using an innovative concept. With this new pump design the axial length will be reduced by 60% and 20% mass weight towards a classic two stage ...

Feeding and growth of Atlantic cod (Gadus morhua L.) in the eastern Baltic Sea under environmental change

open access: yesICES Journal of Marine Science, 2019
Five decades of stomach content data allowed insight into the development of consumption, diet composition, and resulting somatic growth of Gadus morhua (Atlantic cod) in the eastern Baltic Sea. We show a recent reversal in feeding level over body length.

Catastrophic dynamics limit Atlantic cod recovery

open access: yesProceedings of the Royal Society B, 2019
Collapses and regime changes are pervasive in complex systems (such as marine ecosystems) governed by multiple stressors. The demise of Atlantic cod (Gadus morhua) stocks constitutes a text book example of the consequences of overexploiting marine living

Enhanced and balanced microalgal wastewater treatment (COD, N, and P) by interval inoculation of activated sludge.

open access: yesJournal of Microbiology and Biotechnology, 2019
Although chemical oxygen demand (COD) is an important issue for wastewater treatment, COD reduction with microalgae has been less studied compared to nitrogen or phosphorus removal.

Trans-oceanic genomic divergence of Atlantic cod ecotypes is associated with large inversions

open access: yesHeredity, 2017
Chromosomal rearrangements such as inversions can play a crucial role in maintaining polymorphism underlying complex traits and contribute to the process of speciation.
