Carbon cycling between surface and mantle reservoirs is pivotal in fostering habitability of Earth. A critical yet poorly constrained parameter is whether crustal carbon can “survive” devolatilization processes that accompany slab subduction and therefore influence deep carbon budgets. Carbonatites provide a key record to address this important topic. Here, we present high-precision potassium isotope ...

A particular laser harmonic with an effective combination of process parameters can break plastic bonds by surpassing the dissociation threshold. Exploring this direction is imperative to uncover new physics and chemistry related to laser-high-density polyethylene (HDPE) interactions and to understand the phenomena occurring during laser induced degradation. An experiment was conducted in an open-air ...

Esta tesis analiza la novela Casas vacías (2019) de Brenda Navarro desde una perspectiva socioliteraria y feminista, con el objetivo de mostrar cómo la obra desmitifica la maternidad como fuente de identidad y realización personal. A través de las voces de dos mujeres –una madre biológica y otra que secuestra a su hijo– la novela cuestiona los ideales de la “buena madre” y revela cómo las ...

This thesis explores the intersection of Norwegian extractivism and its colonial echoes in Barcarena, Pará, Brazil, with a focus on the impact of mining activities tied to Norsk Hydro’s Alunorte/Albras complex, specifically in the bauxite refining and aluminum production processes. Drawing on decolonial and activist research frameworks, this study critically examines the contradictions in Norway’s ...

Denne oppgaven diskuterer funn fra Avaldsnes, Karmøy k., med en «bricolage»-tilnærming. Det vil si at det teoretiske grunnlaget ble plukket fra forskjellige plasser. Fenomenlogi, objekt-orientert ontologi, filosofi, ting-teori og ikke-atroposentrisme er noen av de mest fremtredende vinklingene i den forbindelse. Istedenfor å kun gjøre en kulturhistorisk analyse av materialet fra Avaldsnes, blir det ...

Large volcanic eruptions strongly influence the internal variability of the climate system. Reliable estimates of the volcanic eruption response as simulated by climate models are needed to reconstruct past climate variability. Yet, the ability of models to represent the response to both single-eruption events and a combination of eruptions remains uncertain. We use the Community Earth System Model ...

Den 27. november 2024 ble det første nasjonale symposium for meritterte undervisere i Norge arrangert ved NMBU. Formålet var å skape en arena for dialog og erfaringsutveksling på tvers av institusjonene, for å lære av hverandre og diskutere hvordan meritterte undervisere best kan bidra til økt undervisningskvalitet. <p> <p>Erfaringer fra symposiet viser et tydelig behov for nasjonal samordning ...

I dagens samfunn utvikler teknologien seg med stormskritt. Dette gjelder både innenfor vitenskapen og naturvitenskapen. På bakgrunn av den økende teknologiske utviklingen i samfunnet, må samfunnet stadig finne nye måter å tilpasse seg hverdagen på, både i hvordan vi bruker teknologien og rettferdiggjør bruken av teknologien. Et eksempel på dette er bruken av genetisk matreale som sædceller og ...

Successful adoption of evidence-based primary prevention interventions by schools is important for public health but relies on multiple factors. Using a systems perspective enables the identification of the interconnectivity and feedback loops among these factors, which can facilitate or hinder adoption. This study aimed to conceptualize a system structure showing how adoption factors are interrelated, ...

This article presents characteristics of geological and tectonic structures of the Kuljuktau Mountains, mineralogical and geochemical features of its volcanic and intrusive rocks and associated mineralisation of critical elements. The Taskazgan graphite, Shaidaraz lithium, and Tozbulak high-purity quartz deposits, and new prospects for rare earth mineralisation have been identified as the most ...
