Purpose The purpose of this study was to examine the efect of pole length on performance and technique selection during a simulated skating cross-country (XC) skiing competition on snow in female XC skiers.<p> <p>Methods Nine female XC skiers and biathletes (VO_2max 63.6±6.2 mL/min/kg, age 22.9±3.5 years, body height 1.69±0.1 m and body mass 60.8±4.6 kg) completed two 5-km skating ...

Salmon Gill Poxvirus Disease (SGPVD) has emerged as a cause of acute mortality in Atlantic salmon (Salmo salar L.) presmolts in Norwegian aquaculture. The clinical phase of the disease is associated with apoptotic cell death in the gill epithelium causing acute respiratory distress, followed by proliferative changes in the regenerating gill in the period after the disease outbreak. In an ...

The present study evaluated whether subjects’ expectations and neurofeedback training performance predict neurofeedback efficacy in cognitive training by controlling both factors as statistical variables. Twenty-two psychology students underwent neurofeedback training, employing beta/theta protocol to enhance beta1 power (13–21 Hz) and suppress theta (4–7 Hz) power. Neurofeedback efficacy was evaluated ...

<b>Background</b> <p>Several members of the bacterial <i>Halomonadacea</i> family are natural producers of polyhydroxyalkanoates (PHA), which are promising materials for use as biodegradable bioplastics. Type-strain species of <i>Cobetia</i> are designated PHA positive, and recent studies have demonstrated relatively high PHA production for a few strains within this genus. Industrially relevant ...

I 1919 bygde Tromsø kommune en demning i Slettaelva på den fjellrike Kvaløya vest for byen som de neste par årene ble koblet via et undersjøisk rør til byens vannforsyningssystem for å øke vannmengden og bedre kvaliteten på byens drikkevann. Nyttårsaften 1921 ble kvaløyvannet trykksatt i Tromsø sentrum. For å undersøke hvilken effekt dette hadde på barnedødeligheten, ble medisinalberetningene og ...

During the era of biodiversity loss, a complete species census and understanding where the different species occur is of high priority. Even though this knowledge has increased tremendously, mainly with expanded use of integrated taxonomic identification, there are groups where our knowledge is very limited, both in terms of diversity and distribution. Ctenophores are such a group. Due to a lack of ...

Autofluorescent granules of various sizes were observed in primary human liver endothelial cells (LSECs) upon laser irradiation using a wide range of wavelengths. Autofluorescence was detected in LAMP-1 positive vesicles, suggesting lysosomal location. Confocal imaging of freshly prepared cultures and imaging flow cytometry of non-cultured cells revealed fluorescence in all channels used. Treatment ...

The Fram Strait plays a crucial role in regulating the heat and sea-ice dynamics in the Arctic. In response to the ongoing global warming, the marine biota of this Arctic gateway is experiencing significant changes with increasing advection of Atlantic species. The footprint of this ‘Atlantification’ has been identified in isolated observations across the plankton community, but a systematic, ...

Most cities, including small and medium ones, experience diverse multicultural populations. The sustainability of such diverse cities requires them to be capable of living with differences and diversity without producing new social inequalities and sustaining old ones. We argue that there is a need for a new conceptualization with which to approach cultural diversity, differences and similarities ...

Traditionally, product deletion is a reactive decision driven by low sales volume and profit margin. However, the complexities involved in product management and consumer behavior volatilities make it necessary to account for a broad range of financial and non-financial factors. Besides, proactive product deletion may be required for a company to reduce the risk of draining resources, adjust to the ...
