Hydrotermisk omdanning av biorest fra Bergen biogassanlegg og analyse av produkt ved EA, GC-MS, IR og NMR
(Master thesis, 2019-12-20)Verdens energibehov og bruken av fossile brensler øker. Dette fører til økt interesse for fornybare og bærekraftige energikilder. Biomasse er, ved riktig og fornuftig bruk, et godt alternativ til en slik energikilde. ... -
Hydrotermisk omdanning av biorest fra biogassanlegget i Rådalen og analysering av produkter ved EA, GC-MS, IR og SPE
(Master thesis, 2019-12-20)I løpet av de siste årene har fokuset på de globale klimaendringene økt kraftig. Dette har ført til mer miljøvennlige metoder for å behandle avfall. Bergen Kommune har etablert et anlegg som produserer biogass fra kloakkslam ... -
Hydrothermal circulation and oil migration at the root of the heterogeneous micro-structure of carbonaceous material in the 2.0 Ga Zaonega Formation, Onega Basin, Russia
(Journal article; Peer reviewed, 2020)Organic-rich rocks of the 2.0 Ga Zaonega Formation, Karelia, Russia, have been studied extensively to gain understanding of the global carbon cycle and reconstruction of paleo-environments, directly after the Great Oxidation ... -
Hydrothermal fluid flow triggered by an earthquake in Iceland
(Journal article; Peer reviewed, 2022)Microearthquake hypocenters were analyzed in the Krýsuvík geothermal area in SW-Iceland with data taken from two consecutive passive seismic surveys, 2005 and 2009. Five years prior to the 2005 survey, this area was struck ... -
Hydrothermal liquefaction of sewage sludge anaerobic digestate for bio-oil production: Screening the effects of temperature, residence time and KOH catalyst
(Journal article; Peer reviewed, 2022)Due to sewage sludge being an abundant biobased resource, and with the number of biogas plants utilizing sewage sludge increasing, digested sewage sludge (DSS) is a promising feedstock for producing bio-oil. This study ... -
Hydrothermal vent fields and chemosynthetic biota on the world's deepest seafloor spreading centre
(Journal article, 2012-01-10)The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal ... -
HyperHMM: efficient inference of evolutionary and progressive dynamics on hypercubic transition graphs
(Journal article; Peer reviewed, 2023)Motivation: The evolution of bacterial drug resistance and other features in biology, the progression of cancer and other diseases and a wide range of broader questions can often be viewed as the sequential stochastic ... -
HyperTraPS: Inferring probabilistic patterns of trait acquisition in evolutionary and disease progression pathways
(Peer reviewed; Journal article, 2020)The explosion of data throughout the biomedical sciences provides unprecedented opportunities to learn about the dynamics of evolution and disease progression, but harnessing these large and diverse datasets remains ... -
Hypothalamic agrp and pomc mRNA Responses to Gastrointestinal Fullness and Fasting in Atlantic Salmon (Salmo salar, L.)
(Journal article; Peer reviewed, 2020-02-11)The orexigenic agouti-related protein (AgRP) and the anorexigenic pro-opiomelanocortin (POMC) are crucial players in the control of feed intake in vertebrates, yet their role in teleosts has not been fully established. ... -
Hypoxia adapted relative biological effectiveness models for proton therapy: a simulation study
(Journal article; Peer reviewed, 2022)In proton therapy, a constant relative biological effectiveness (RBE) factor of 1.1 is applied although the RBE has been shown to depend on factors including the Linear Energy Transfer (LET). The biological effectiveness ... -
Hypoxia tolerance and responses to hypoxic stress during heart and skeletal muscle inflammation in Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2017-07-11)Heart and skeletal muscle inflammation (HSMI) is associated with Piscine orthoreovirus (PRV) infection and is an important disease in Atlantic salmon (Salmo salar) aquaculture. Since PRV infects erythrocytes and farmed ... -
