Hydrology influences breeding time in the white‑throated dipper
(Peer reviewed; Journal article, 2020)Background: Earlier breeding is one of the strongest responses to global change in birds and is a key factor determining reproductive success. In most studies of climate effects, the focus has been on large-scale environmental ... -
Hydrolysater av restråstoff fra laks (Salmo salar) - effekten av antioksidanter på kvaliteten under lagring
(Master thesis, 2020)Årlig genererer oppdrett av laks (Salmo salar) og regnbueørret (Oncorhynchus mykiss) i Norge flere hundre tusen tonn restråstoff. Dette restråstoffet inneholder verdifulle omega-3-fettsyrer og lett-fordøyelige proteiner. ... -
Hydrolyse av marint restråstoff – karakterisering av hydrolysat fra norsk vårgytende sild (Clupea harengus) og melke fra torsk (Gadus morhua Linnaeus)
(Master thesis, 2021)Abstract will be available on 2024-05-15 -
Hydrolyse av restråstoff fra regnbueørret (Oncorhynchus mykiss) - effekten av antioksidanter på kvalitet under lagring
(Master thesis, 2020)Enzymatisk hydrolyse av restråstoff fra fisk gir fiskeproteinhydrolysat (FPH) som har funksjonelle egenskaper som er egnet for matindustrien. Målet med denne oppgaven var å studere endringer i egenskaper til FPH tilsatt ... -
Hydrolyse og membranfiltrering for økt utnyttelse av seihoder – karakterisering av proteinhydrolysat og antioksidative peptider
(Master thesis, 2021)For at vi skal kunne skape og høste fra havet i fremtiden, må vi ta vare på de ressursene havet gir oss. Økt bærekraftig utnyttelse av marine ressurser kan være en av flere løsninger for å møte befolkningsvekst og overforbruk ... -
Hydrolysis activity of pyloric cecal enterocytes of brown trout (Salmo trutta) toward monoacylglycerol and lysophosphatidylcholine
(Journal article; Peer reviewed, 2018)Some lipid digestion pathways in fish deviate from those in mammals, and many differences may also be species dependent. This report describes a pathway for monoacylglycerol (MAG) and lysophospholipid absorption by intestinal ... -
Hydrolysis improves the inhibition efficacy of bovine lactoferrin against infection by SARS-CoV-2 pseudovirus
(Peer reviewed; Journal article, 2022)The entry of SARS-CoV-2 into host cells may involve the spike protein cleavage by cathepsin L (CTSL). Certain food proteins such as lactoferrin (Lf) inhibit CTSL. The current study investigated the impact of hydrolysis ... -
Hydrolysis of Cellulose using Hybrid Catalysts
(Master thesis, 2016)Catalyst plays an important role in biomass conversion. The present work will deal with preparation, characterization and application in the cellulose conversion to chemicals. The work will focus on the functionalization ... -
Hydrolysis of Marine Cod (Gadus Morhua) Head - Utilization of rest raw material from cod for production of ingredients for human consumption
(Master thesis, 2015)The main objective of this study was to determine the possibility of utilizing frozen marine cod head for further processing into high-quality and high-yield fish protein hydrolysates. The project included determination ... -
Hydrolysis of Rest Raw Material From Chicken: Effect of Processing Conditions on Yields and Product Properties, With Extended Focus on the Sediment Fraction
(Master thesis, 2021)Den globale produksjonen av kyllingkjøtt forventes å nå 102,9 millioner tonn innen utgangen av 2021. Dette vil generere en stor mengde restråstoff, som kan bli bearbeidet til produkter av høyere verdi. Gjennom enzymatisk ... -
Hydrometallurgical Purification of Magnesium-Doped Silicon by Different Acids
(Chapter, 2017)The purification of commercial metallurgical grade silicon through alloying and then acid leaching is studied. Magnesium is added into molten silicon and then acid leaching of the solidified Si-Mg alloy by HCl, H2SO4 and ... -
Hydropeaking Effects on Riverine Benthic Invertebrate Fauna Composition and Drift
(Master thesis, 2015)In earlier studies, changes have been detected in the composition of the lotic benthic macroinvertebrate fauna as a consequence of hydropeaking. Rapid fluctuations in discharge lead to sudden dewatering of river bed area ... -
