Iridium-PHOX-mediated alkene hydrogenation: Isomerisation influences the stereochemical outcome
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-05-27)
Recent experimental studies of iridium-phosphinooxazoline-mediated alkene hydrogenation indicated two dihydride species as resting states, with the minor isomer assumed to give rise to the major product enantiomer [Gruber and Pfaltz, Angew. Chem. Int. Ed. 2014, 53, 1896]. B3LYP-D2 calculations confirm the two dihydride intermediates as resting states but show that these species do not give rise to ...
Effects of chronic dietary petroleum exposure on reproductive development in polar cod (Boreogadus saida)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-10-04)
Increasing human activities in the Arctic raise the risk of petroleum pollution, thus posing an elevated risk for Arctic organisms to be chronically exposed to petroleum compounds. The endocrine disrupting properties of some of these compounds (i.e. polycyclic aromatic hydrocarbons [PAHs]) present in crude oil may have negative effects on the long and energy intensive reproductive development of ...
An empirical evaluation of spatial value transfer methods for identifying cultural ecosystem services
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-04-09)
A significant barrier to the assessment of ecosystem services is a lack of primary data, especially for cultural ecosystem services. Spatial value transfer, also known as benefits transfer, is a method to identify the probable locations of ecosystem services based on empirical spatial associations found in other geographic locations. To date, there has been no systematic evaluation of spatial value ...
A qualitative case study on agile practices and project success in agile software projects
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05)
In project management, and particularly software project management, there has been a shift from traditional
plan based project management, to the agile event driven project management style. This paper
identifies some of the most important agile practices a team should use, to succeed in an agile software
project. Four participants in two different projects were interviewed. 53 often used practices ...
Comparison of non-invasive individual monitoring of the training and health of athletes with commercially available wearable technologies
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-03-09)
Athletes adapt their training daily to optimize performance, as well as avoid fatigue,
overtraining and other undesirable effects on their health. To optimize training load, each athlete
must take his/her own personal objective and subjective characteristics into consideration and an
increasing number of wearable technologies (wearables) provide convenient monitoring of various
parameters. ...
Multilocus sequence typing and ftsI sequencing: a powerful tool for surveillance of penicillin-binding protein 3-mediated beta-lactam resistance in nontypeable Haemophilus influenzae
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)
Background
Beta-lactam resistance in Haemophilus influenzae due to ftsI mutations causing altered penicillin-binding protein 3 (PBP3) is increasing worldwide. Low-level resistant isolates with the N526K substitution (group II low-rPBP3) predominate in most geographical regions, while high-level resistant isolates with the additional S385T substitution (group III high-rPBP3) are common in Japan ...
Integrated Monitoring of Mola mola Behaviour in Space and Time
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-05)
Over the last decade, ocean sunfish movements have been monitored worldwide using various satellite tracking methods. This study reports the near-real time monitoring of fine-scale (< 10 m) behaviour of sunfish. The study was conducted in southern Portugal in May 2014 and involved satellite tags and underwater and surface robotic vehicles to measure both the movements and the contextual environment ...
Total synthesis of tubastrine and 3-dehydroxy tubastrine by microwave-assisted cross-coupling reactions
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-03)
The first syntheses of tubastrine and 3-dehydroxy tubastrine are described. The target compounds were prepared in four consecutive steps from commercially available starting materials. The central scaffold was formed by a microwave-assisted C–N cross-coupling reaction between 1,3-bis(<i>tert</i>-butoxycarbonyl)-guanidine and (<i>E</i>)-((4-(2-iodovinyl)-1,2-phenylene)bis(oxy))bis(<i>tert</i>-butyl ...
Hvorfor er det så himla viktig med utdanning?
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-03)
Frafall fra utdanning er et hyppig debattert tema både i Norge og andre steder. Denne opptattheten av å redusere frafallet har blant annet bakgrunn i de mange positive konsekvensene utdanning har for helse, jobbstatus og økonomi. Statistikkene viser at flere gutter enn jenter slutter, og at frafallet er størst på yrkesfagene. Foreldres utdanningsnivå betyr mye for om elevene fullfører eller ikke. ...
Analytical and Case Studies of a Sandwich Structure using Euler-Bernoulli Beam Equation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-11)
This paper presents analytical and case studies of sandwich structures. In this study, the Euler-Bernoulli beam equation is solved analytically for a four-point bending problem. Appropriate initial and boundary conditions are specified to enclose the problem. In addition, the balance coefficient is calculated and the Rule of Mixtures is applied. The focus of this study is to determine the effective ...
