High thresholds for avoidance of sonar by free-ranging long-finned pilot whales (Globicephala melas)
(2014)
The potential effects of exposing marine mammals to military sonar is a current concern. Dose–response relationships are useful for predicting potential environmental impacts of specific operations. To reveal behavioral ...
Chirped pulses sum frequency generation for deep-UV picosecond pulse shaping
(2012)
We show by experiments and simulations that properly chirped laser pulses enable efficient and broadband sum frequency generation in nonlinear crystals. We achieved high energy, picosecond deep-UV pulses with spectral ...
Supralethal poisoning by any of the classical nerve agents is effectively counteracted by procyclidine regimens in rats
(2015)
A treatment regimen consisting of HI-6, levetiracetam, and procyclidine (termed the triple regimen) has previously been shown to work as a universal therapy against soman poisoning in rats, since it has capacities to ...
Identification of airborne bacteria by 16S rDNA sequencing, MALDI-TOF MS and the MIDI microbial identification system
(2015)
The aim of this study was to collect and identify airborne bacteria in Norway, Sweden and Finland and to compare three different technologies for identifying collected airborne bacterial isolates: the “gold standard” method ...
Botulism outbreaks in natural environments - an update
(2014)
Clostridium botulinum comprises a diverse group of botulinum toxin-producing anaerobic rod-shaped spore-forming bacteria that are ubiquitously distributed in soils and aquatic sediments. Decomposition of plants, algae, and ...
Study of the seasonal ozone variations at European high latitudes
(2011)
The geographic area at high latitudes beyond the polar circle is characterized with long darkness during the winter (polar night) and with a long summertime insolation (polar day). Consequentially, the polar vortex is ...
Predator sound playbacks reveal strong avoidance responses in a fight strategist baleen whale
(2015)
Anti-predator strategies are often defined as ‘flight’ or ‘fight’, based upon prey anatomical adaptations for size, morphology and weapons, as well as observed behaviours in the presence of predators. The humpback whale ...
Deletion of the γ-aminobutyric acid transporter 2 (GAT2 and SLC6A13) gene in mice leads to changes in liver and brain taurine contents
(2012)
The GABA transporters (GAT1, GAT2, GAT3, and BGT1) have mostly been discussed in relation to their potential roles in controlling the action of transmitter GABA in the nervous system. We have generated the first mice lacking ...
Interstate Relations in the Arctic: An Emerging Security Dilemma?
(2014)
The five states that surround the Arctic Ocean— Russia, Canada, the United States, Denmark, and Norway—have in recent years taken various measures to protect their economic and security interests in the north. The measures ...
