Use of probiotics in aquaculture of China—a review of the past decade
(Peer reviewed; Journal article, 2019)China is the largest aquaculture producer in the world. Antibiotics were extensively used to ensure the development of the intensive aquaculture; however, the use of antibiotics causes safety- and environment-associated ... -
Use of Pulse Amplitude Modulated (PAM) Fluorescence and Bio-optics for Assessing Microalgal Photosynthesis and Physiology
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:183, Doctoral thesis, 2011)This thesis puts emphasis on an evaluation of the Pulse Amplitude Modulated (PAM) fluorescence (that is, the in vivo variable Chl a fluorescence) as non-invasive means to estimate the oxygen evolution rate. The estimated ... -
Use of selective cultivation regimes for microalgae to improve lipid and/or: Nannochloropsis
(Master thesis, 2013)Det kan være aktuelt å kjøre forsøkene med en eller to mikroalger. Basert på en algekultur vil det bli etablert 96 kloner som skal dyrkes i brønnplater under et fastsatt seleksjonsregime. Etter et visst antall doblinger ... -
The use of soluble gas stabilization technology on food – A review
(Peer reviewed; Journal article, 2021)Background Increasing the shelf life of perishable food products contributes to lower food waste and the possibility of widening distribution outreach in the food value chain. Soluble gas stabilization (SGS) technology ... -
Use of Spectroscopic Techniques for a Rapid and Non-Destructive Monitoring of Thermal Treatments and Storage Time of Sous-Vide Cooked Cod Fillets
(Peer reviewed; Journal article, 2020)In this work, the potential of spectroscopic techniques was studied to investigate heat-induced changes occurring during the application of thermal treatments on cod (Gadus morhua L.) fillets. Vacuum-packed samples were ... -
Use of translocated topsoil to enhance native biodiversity in the urban landscape of NTNU Campus in Trondheim
(Master thesis, 2024)Restaurering av degraderte habitater ved bruk av naturbaserte løsninger er nødvendig for å redusere den negative påvirkningen menneskelig aktivitet har på naturen. En foretrukket metode ved veibygge prosjekter i Norge er ... -
Use of Wastewater from Recirculating Aquaculture System (RAS) for Cultivation of Microbial Biofilm Communities
(Master thesis, 2023)Den økende etterspørselen etter bærekraftig mat kan delvis løses ved produksjon av akvatiske arter i resirkulerende akvakultursystemer (RAS). I norsk havbruksnæring blir atlantisk laks (Salmo salar) ofte klekket og kultivert ... -
Use, selection, and home range properties: complex patterns of individual habitat utilization
(Journal article; Peer reviewed, 2019)Individual patterns of habitat use emerge from behavioral decisions driven by interactions between landscape characteristics and individual traits. Individual traits, such as age and sex, influence the net gain of using ... -
Using a low-cost high throughput microscope in cultivated seaweed farms for early biofouling detection
(Master thesis, 2024)Begroing på kultivert tare som følge av mosdyrkolonier er en av hovedutfordringene for tareindustrien i Midt- og Sør-Norge. Membranipora membranacea og Electra pilosa er to fremtredende mosdyrarter som fører til begroing ... -
Using a neural network for estimating plant gradients in real-time optimization with modifier adaptation
(Journal article; Peer reviewed, 2019)In the presence of structural plant-model mismatch, standard real-time optimization (RTO) schemes are prone to compute an operation point that does not coincide with the plant optimum. Modifier Adaptation (MA) methods are ... -
Using AERMOD to predict the dispersion of emissions from the aluminum industry
(Master thesis, 2022)Økt fokus på de miljøskadelige effektene av utslipp har gitt opphav til strengere krav i sammenheng med utsippskontroll i aluminiumsindustrien. Derfor ønsker industrien å innføre effektive måter å estimere dispersjonen av ... -
