Nesna University College is a university college, a Norwegian state institution of higher education. It is one of the 24 Norwegian state university colleges, and is located in the municipality of Nesna in Helgeland, Nordland county. It was established in 1918 as Nesna Teachers' College, and was reorganised as a state university college on 1 August 1994 following the university college reform. Today, the university college has approximately 1200 students and 130 employees. The original teachers' college was established in 1918 by the local priest, Ivar Hjellvik, making it the second oldest institution of higher education in Northern Norway. This university college has permanent satellite campuses in the neighboring towns of Mo i Rana and Sandnessjøen. Nesna University College hosts the Nordic Women's University. Wikipedia.

Adsorption and desorption of CO on clean and CO pre-covered Mo(1 1 0) have been studied by temperature programmed desorption (TPD), low energy electron diffraction, X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy. It was found that adsorption and subsequent desorption of CO from Mo(1 1 0) and CO pre-covered Mo(1 1 0) show large differences in the TPD spectra in the low temperature region from 150 to 400 K. In the case of the pre-covered sample a dramatically increased width to lower temperatures was observed. The increased width at higher CO coverage is argued to result from a distribution of adsorption sites and increased lateral interactions between adsorbed CO molecules. © 2015 Elsevier B.V.

Hydrogen adsorption/desorption on potassium doped carbon nanocones was studied by temperature programmed desorption (TPD), X-ray photoelectron spectroscopy, and ultraviolet photoelectron spectroscopy. TPD shows that the hydrogen storage was enhanced by up to 40% after potassium doping. Hydrogen adsorption on K-modified carbon nanocone material seems more stable than that on the undoped material. The XPS results indicate that there is charge transfer from potassium to carbon. The C 1s binding energy increases with increased potassium doping and the peak becomes wider. These binding energy shifts may be explained by work function changes related to potassium doping. The K 2p spectra indicate that there are two different local environments for potassium on the carbon cone material. © 2013 Elsevier B.V. Source

Introduction: The current study compared differences in cycle characteristics, energy expenditure and peak speed between double poling (DP) and G3 skating. Methods: Eight world class male sprint skiers performed a 5-min submaximal test at 16 km h−1 and an incremental test to exhaustion at a 5 % incline during treadmill roller skiing with two different techniques: DP where all propulsion comes from poling, and G3 skating where leg skating is added to each double poling movement. Video analyses determined cycle characteristics; respiratory parameters and blood lactate concentration determined the physiological responses. Results: G3 skating resulted in 16 % longer cycle lengths at 16 % lower cycle rates, whereas oxygen uptake was independent of technique during submaximal roller skiing. The corresponding advantages for G3 skating during maximal roller skiing were reflected in 14 % higher speed, 30 % longer cycle length at 16 % lower cycle rate and 11 % higher peak oxygen uptake (all p < 0.05). Conclusions: Compared to DP approximately 14 % higher speed was achieved when leg push-offs were added in G3 skating. This was done by major increases in cycle lengths at slightly lower cycle rates and a higher aerobic energy delivery. However, the oxygen uptake for a given submaximal speed was not affected by technique although higher cycle rate was used in DP. © 2014, Springer-Verlag Berlin Heidelberg. Source

This paper presents knowledge about the ecology and botanical biodiversity in Holmvassdalen naturereserve in the southern part of Nordland county. This area has a rich flora and funga connected to calcareous birch and spruce forests, and the number of botanical red-listed species is more than 120. A number of nature types are represented in the area, of which several are red-listed. Furthermore, the article presents historical documentation concerning agrarian and sami land-use, as Holmvassdalen has been influenced by human activities for a long time through cultivation, forestry and different grazing. A study shows that immigration of spruce happened regionally about one thousand years ago. As a consequence the first clusters of distribution may be twice as old. Besides, the logging history in the area emphasizes clearly that the forest has never been clearcut. An interesting result of these factors is a whole range of rare and highly specialized species of mycorrhiza fungi connected to calcareous spruce forest growing in the area. All in all, several factors indicate long time ecological continuity in Holmvassdalen nature reserve. Source

Purpose: The aim of the present study was to investigate effects of low cadence training at moderate intensity on aerobic capacity, cycling performance, gross efficiency, freely chosen cadence, and leg strength in veteran cyclists. Method: Twenty-two well trained veteran cyclists [age: 47 ± 6 years, maximal oxygen consumption (VO2max): 57.9 ± 3.7 ml · kg-1 · min-1] were randomized into two groups, a low cadence training group and a freely chose cadence training group. Respiratory variables, power output, cadence and leg strength were tested before and after a 12 weeks training intervention period. The low cadence training group performed 12 weeks of moderate [73-82% of maximal heart rate (HRmax)] interval training (5 × 6 min) with a cadence of 40 revolutions per min (rpm) two times a week, in addition to their usual training. The freely chosen cadence group added 90 min of training at freely chosen cadence at moderate intensity. Results: No significant effects of the low cadence training on aerobic capacity, cycling performance, power output, cadence, gross efficiency, or leg strength was found. The freely chosen cadence group significantly improved both VO2max (58.9 ± 2.4 vs. 62.2 ± 3.2 ml · kg-1 · min-1), VO2 consumption at lactate threshold (49.4 ± 3.8 vs. 51.8 ± 3.5 ml · kg-1 · min-1) and during the 30 min performance test (52.8 ± 3.0 vs. 54.7 ± 3.5 ml · kg-1 · min-1), and power output at lactate threshold (284 ± 47 vs. 294 ± 48 W) and during the 30 min performance test (284 ± 42 vs. 297 ± 50 W). Moreover, a significant difference was seen when comparing the change in freely chosen cadence from pre- to post between the groups during the 30 min performance test (2.4 ± 5.0 vs. -2.7 ± 6.2). Conclusion: Twelve weeks of low cadence (40 rpm) interval training at moderate intensity (73-82% of HRmax) twice a week does not improve aerobic capacity, cycling performance or leg strength in highly trained veteran cyclists. However, adding training at same intensity (% of HRmax) and duration (90 min weekly) at freely chosen cadence seems beneficial for performance and physiological adaptations. © 2014 Kristoffersen, Gundersen, Leirdal and Iversen.
