X-ray Microprobe Investigation of Iron During a Simulated Silicon Feedstock Extraction Process
(Peer reviewed; Journal article, 2016)Elemental silicon is extracted through carbothermic reduction from silicon-bearing raw feedstock materials such as quartz and quartzites. We investigate the micron-scale distribution and valence state of iron, a deleterious ... -
X-ray nanoscopy of a bulk heterojunction
(Journal article; Peer reviewed, 2016)Optimizing the morphology of bulk heterojunctions is known to significantly improve the photovoltaic performance of organic solar cells, but available quantitative imaging techniques are few and have severe limitations. ... -
X-ray repair cross complementing protein 1 in base excision repair
(Journal article; Peer reviewed, 2012)X-ray Repair Cross Complementing protein 1 (XRCC1) acts as a scaffolding protein in the converging base excision repair (BER) and single strand break repair (SSBR) pathways. XRCC1 also interacts with itself and rapidly ... -
X-ray Studies of Carbon Dioxide Intercalation in Na-Fluorohectorite Clay at Near-Ambient Conditions
(Journal article, 2012)We show experimentally that gaseous CO2 intercalates into the interlayer space of the synthetic smectite clay Na-fluorohectorite at conditions not too far from ambient. The mean interlayer repetition distance of the clay ... -
X65 steel pipes subjected to combined stretching and bending
(Chapter, 2015)Subsea pipelines are occasionally struck and hooked by objects such as anchors or trawl gear. The initial denting followed by a potential hooking and displacement of the pipeline, with a simultaneous increase in tensile ... -
Xandarovula patula (Gastropoda: Ovulidae) new to Scandinavia
(Journal article; Peer reviewed, 2011)In August 2009 six specimens of the ovulid gastropod Xandarovula patula (Pennant, 1777) (formerly known as Simnia patula Pennant, 1777), were found in dredge samples from a locality west of Smögen in western Sweden (58°22′N ... -
XAS investigation of silica aerogel supported cobalt rhenium catalysts for ammonia decomposition
(Peer reviewed; Journal article, 2020)The implementation of ammonia as a hydrogen vector relies on the development of active catalysts to release hydrogen on-demand at low temperatures. As an alternative to ruthenium-based catalysts, herein we report the ... -
XPS and GDOES characterization of porous coating enriched with copper and calcium obtained on tantalum via plasma electrolytic oxidation
(Peer reviewed; Journal article, 2016)XPS and GDOES characterizations of porous coatings on tantalum after Plasma Electrolytic Oxidation (PEO) at 450 V for 3 minutes in electrolyte containing concentrated (85%) phosphoric acid with calcium nitrate and copper ... -
XPS Examination of the Oxide-Metal Interface of an Aluminum-Magnesium Alloy Containing Beryllium
(Chapter, 2018)The addition of beryllium to high magnesium aluminum alloys has long been known to cause a significant decrease in the rate of alloy oxidation. A clear understanding of the fundamental mechanism behind this effect is still ... -
Xylopsora canopeorum (Umbilicariaceae), a new lichen species from the canopy of Sequoia sempervirens
(Journal article; Peer reviewed, 2018)Xylopsora canopeorum Timdal, Reese Næsborg & Bendiksby is described as a new species occupying the crowns of large Sequoia sempervirens trees in California, USA. The new species is supported by morphology, anatomy, secondary ... -
Yang-Mills connections on quantum Heisenberg manifolds
(Journal article; Peer reviewed, 2020)We investigate critical points and minimizers of the Yang-Mills functional YM on quantum Heisenberg manifolds Dc µν, where the Yang-Mills functional is defined on the set of all compatible linear connections on finitely ... -
Yb-Doped Fiber Lasers Operating in the Range of 1147-1200 nm
(Chapter, 2012)Pump source brightness and heat production per unit fiber length were found to be the critical parameters for the realized and investigated Yb-doped fiber lasers operating in the range of 1147-1200 nm. -
Yb-Tm energy transfer in Y-codoped fibers
(Chapter, 2013)Experimental investigation of Yb-Tm energy transfer process in Yb/Tm-doped fibers with Y-codoping provided a fairly high energy transfer efficiency of 50 %, making lasers based on these glass fibers attractive for diode-pumping ... -
YDFL Operating in 1150-1200-nm Spectral Domain
(Journal article; Peer reviewed, 2013)A family of high-power Yb-doped fiber lasers operated in the range of 1150–1180 nm with output powers of up to 35 W and optical efficiencies up to 60% is realized. Operation at 1200 nm is also demonstrated. Amplified ... -
YKL-40 (Chitinase-3-Like Protein 1) Serum Levels in Aortic Stenosis
(Peer reviewed; Journal article, 2020)BACKGROUND: Identification of novel biomarkers could provide prognostic information and improve risk stratification in patients with aortic stenosis (AS). YKL-40 (chitinase-3-like protein 1), a protein involved in ... -
Yoga for children and young people’s mental health and well-being: research review and reflections on the mental health potentials of yoga
(Journal article; Peer reviewed, 2014)This article discusses yoga as a potential tool for children to deal with stress and regulate themselves. Yoga provides training of mind and body to bring emotional balance. We argue that children and young people need ... -
Yoga, change and embodied enlightenment
(Journal article; Peer reviewed, 2012)Though it has been claimed that modern yoga retains little of its origins of religious austerity, I will argue that even if yoga as a physical practice has taken a strong position among the modern fitness trends, there are ... -
‘You are inferior!’ Revisiting the expressivist argument
(Journal article, 2017)According to the expressivist argument the choice to use biotechnologies to prevent the birth of individuals with specific disabilities is an expression of disvalue for existing people with this disability. The argument ... -
