Through time, we as a society have been tested with infectious disease outbreaks of different magnitude, which often pose major public health challenges. To mitigate the challenges, research endeavors have been focused on early detection mechanisms through identifying potential data sources, mode of data collection and transmission, case and outbreak detection methods. Driven by the ubiquitous nature ...

Temperature fluctuations can be described by a persistent correlation structure known as long-range dependence (LRD). This is a phenomenon which implies that the autocorrelation function follows a power-law decay and that observations may still be significantly correlated even if the temporal or spatial distance between them is large. Moreover, temperature is known to be influenced by radiative ...

Norwegian fjords have a great potential for providing high-resolution sedimentary records that reflect local terrestrial and marine processes and therefore, fjords offer unique opportunities for the investigation of sedimentological and geochemical climatically induced processes. However, the complexity of fjord systems in terms of bathymetry and oceanography requires a profound knowledge of the ...

There is an urgent lack of new antibiotics in the face of an ever-expanding antimicrobial resistance crisis. The fact that fewer new classes of antibiotics are being developed, and resistance soon follows newly available antibiotics, only serves to underline the urgency of the matter. There is a clear need of a paradigm shift with regards to antibiotics, and one such hope is antimicrobial peptides ...

<p>Bacteria are small single-celled organisms that are found in nearly every habitat on Earth. While bacterial genomes usually consist of one large circular replicon, about 10% of bacteria have organized their genes onto several large replicons. These multipartite bacteria are often found in symbiotic or pathogenic relationships with other higher organisms and are believed to have greater ability ...

CO₂ is a renewable source of carbon that has not yet been properly utilized. The reason for this is mostly due to its kinetic and thermodynamic stability. The potential renewability of CO₂, coupled with environmental concerns, has motivated scientists worldwide to develop new artificial carbon cycles for chemical fixation of CO₂. Unfortunately, the pronounced inertness ...

The research undertaken in this PhD project was part of a large EU interdisciplinary project named ECO2: Sub-seabed CO2 Storage: Impact on Marine Ecosystems. The overall goal of the ECO2 project was to understand the short-term and long-term impacts of CO2 storage on marine ecosystems. I concentrated my work on the Snøhvit site, which is located in the SW Barents Sea, on the Norwegian continental ...

Nucleic acid-interacting proteins are essential players in cellular processes of all living organisms. In the present study, we explore three psychrophilic-derived proteins involved in gene regulation, RNA degradation and DNA ligation in bacterial cells, with one common feature; they perform their activity by interacting with nucleic acids. The Ferric uptake regulator (Fur) is a global transcription ...

In this thesis a series of geophysical surveys are carried out on the geologically important and remote Svalbard using magnetotelluric imaging, to constrain better the geology particularly defining geothermal resources. Magnetotellurics (MT) relays on natural source time-varying electric and magnetic field data measured at the earth’s surface in order to derive the subsurface resistivity structure. ...

Type 1 diabetes is a metabolic disorder characterized by high blood glucose levels as a consequence of deficiency of the hormone insulin, requiring the patient to follow a strict personalized protocol of food intake, subcutaneous insulin administration as a lifelong treatment for the high blood glucose levels, and exercise. This condition leads to acute complications, damaging several organs and ...
