(Bachelor thesis, 2024)Et semi-våt design av undersjøiske høyspentkabler (HVSC) har blitt undersøkt som et mulig alternative til tørr-design gjennom analyse av vanntrær, akkumulering av romladninger og urenheter i tverrbundet polyetylen ... -
What underlying mechanisms led the dissociative anesthetic ketamine to be clinically recognized as an antidepressant?
(Bachelor thesis, 2024)Ketamin har vært kjent i medisinsk praksis i flere tiår som et dissosiativt anestesimiddel. På 2000-tallet ble det observert at subanestetiske doser hadde en effekt på pasienter med depressive lidelser. Disse dosene hadde ... -
Green synthesis of gold nanoparticles and its application in cancer treatment
(Bachelor thesis, 2024)Gull nanopartikler (AuNPs) spiller en betydelig rolle i både medisinske og ikke-medisinske felt på grunn av deres unike egenskapene. Grønn syntese metoder tilbyr en miljømessig bærekraftig tilnærming til å produsere AuNP-er ... -
Chemoenzymatic processes as method to produce high enantiopure beta-blockers
(Bachelor thesis, 2024)Kjemoenzymatisk syntese av beta-blokkere har vist høy grad av enantiomer renhet av (S)-enantiomerene til både bisoprolol og metoprolol. På grunn av at prosessen i begge syntesene er rasemisk oppløsning, så er det allerede ... -
Development of Gold Auranofin Analogues against Multidrug Resistant Bacteria Including Neisseria Gonorrhoeae
(Bachelor thesis, 2024)Denne oppgaven vil presentere en gjennomgang av nyere forskning på medikamentet Auranofin,som ble godkjent av det amerikanske legemiddelverket (FDA) som et antiaritmetisk legemiddel. Auranofin er ett gull basert medikament ... -
Potential natural antibiotic: Application of and comparison of synthetic routes to (-)-Hygromycin A
(Bachelor thesis, 2024)Overdrevent bruk av antibiotika har gitt en kraftig økning i antimikrobiell resistens. Dette er en av de største trusslene innen helse, og kan gi en kraftig økning i dødelighet hvis det ikke tas p˚a alvor. Overforbruket ... -
Stiripentol as Treatment for Epileptic Seizures
(Bachelor thesis, 2024)I denne oppgaven skal stiripentols mekanismer mot epilepsi diskuteres. Stiripentol er et legemiddel mest brukt mot Dravet syndrom, en sjelden barneepilepsi med høy dødsrate. Mekanismene mot epilepsi består av enzyminhibering, ... -
Exploring the effect of various assumptions for Bondi-Hoyle-Lyttleton accretion in High-mass X-ray binaries
(Bachelor thesis, 2024)This project explores the phenomenon of Bondi-Hoyle-Lyttleton (BHL) accretion, which plays a crucial role in astrophysical processes such as star formation, accretion onto compact objects, and binary star evolution. The ... -
Mercury pathways in the Arctic and possible future trends caused by climate change
(Bachelor thesis, 2024)Arktis opplever betydelige endringer som følge av klimaendringer, inkludert høyere temperaturer, tap av sjøis, og økt skogbrannaktivitet. Disse endringene påvirker kvikksølv (Hg)-syklusen, med komplekse konsekvenser for ... -
Effect of Copper Catalyst Content and Zinc Promoter on Carbon Formation in the Direct Synthesis of Methylchlorosilanes
(Journal article; Peer reviewed, 2023)Direct synthesis of methylchlorosilanes (MCS) is a complex solid–gas–solid reaction where solid silicon (Si) reacts with chloromethane (CH3Cl) in the presence of a copper (Cu)-based catalyst, and coke formation by cracking ... -
Evolvability predicts macroevolution under fluctuating selection
(Peer reviewed; Journal article, 2024)Heritable variation is a prerequisite for evolutionary change, but the relevance of genetic constraints on macroevolutionary timescales is debated. By using two datasets on fossil and contemporary taxa, we show that ... -
