Agglomeration of charged ice and dust particles in the mesosphere and lower thermosphere is studied using a classical electrostatic approach, which is extended to capture the induced polarisation of surface charge. Collision outcomes are predicted whilst varying the particle size, charge, dielectric constant, relative kinetic energy, collision geometry and the coefficient of restitution. In addition ...

Planktic foraminifera and shelled pteropods are some of the major producers of calcium carbonate (CaCO₃) in the ocean. Their calcitic (foraminifera) and aragonitic (pteropods) shells are particularly sensitive to changes in the carbonate chemistry and play an important role for the inorganic and organic carbon pump of the ocean. Here, we have studied the abundance distribution of planktic ...

We report new findings of total electron content (TEC) perturbations in the southern hemisphere at conjugate locations to the northern eclipse on August 21, 2017. We identified a persistent conjugate TEC depletion by 10%–15% during the eclipse time, elongating along magnetic latitudes with at least ∼5° latitudinal width. As the Moon's shadow swept southward, this conjugate depletion moved northward ...

Workshop methodologies based on overarching knowledge structures are necessary for a shift of the tourism sector towards sustainability. We adopted a participatory action research approach and designed a workshop methodology based on the main tenets and tools of the theory of change, design thinking, and sustainable business models. We tested this methodology within a project initiated by a destination ...

Masteravhandlingen tar for seg et av konsernrettens grunnproblemer. Aksjeloven/allmennaksjeloven § 3-9 (1) 1.pkt. legger til grunn et utgangspunkt for reguleringen av konserninterne transaksjoner. Bestemmelsen har vært gjenstand for omfattende behandling. På grunn av spenningsforholdet mellom konsernet som en samling av flere selvstendige selskaper på den ene siden og konsernet som en økonomisk og ...

The issue of attrition from higher education is a significant problem across Europe and especially Norway, where dropout rates are as high as 20-25%. In the current study, we address the issue from the perspective of attrition intentions that have been found closely associated with actual attrition behavior. In particular, we attempted to differentiate between types of students’ attrition intentions: ...

Bakgrunn: Økt tilgjengelighet på prevensjon og relevante helsetjenester er viktige faktorer for å redusere antall provoserte aborter. De siste årene har det vært en betydelig reduksjon i antall aborter blant tenåringsjenter i Finnmark og landet forøvrig. Dette etter at det har vært igangsatt flere nasjonale tiltak gjennom handlingsplaner. Finnmark har tradisjonelt hatt høy abortforekomst i Norge og ...

Introduksjon: Osteoporose er en sykdom som rammer skjelettet i form av redusert beintetthet (BMD), og som gir økt risiko for brudd. Måling av BMD er sentralt i diagnostikk av sykdommen. Formålet med denne studien er å avdekke hvor mange av pasientene med vertebrale kompresjonsbrudd som ble fulgt opp med måling av BMD innen to år, samt om kjønn, alder og tilstedeværelse av kjent osteoporose eller ...

Vaginal infections are common in women of all ages and proper treatment is essential. The vaginal route of administration can be considered as favourable for the local therapy of vaginal infections. There are several vaginal dosage forms currently available; however, all suffer from limitations such as leakage and limited residence time at the site of action resulting in reduced therapeutic effect. ...

Skin cancer is one of the most common types of cancer and is usually classified as either non-melanoma and melanoma skin cancer. Melanoma skin cancer accounts for about half of all skin cancer-related deaths. The 5-year survival rate is 99% when the cancer is detected early but drops to 25% once it becomes metastatic. In other words, the key to preventing death is early detection. Foraminifera ...
