Walvis Ridge Hotspot : drilling Walvis Ridge, Southeast Atlantic Ocean, to test models of ridge-hotspot interaction, isotopic zonation, and the hotspot reference frame

Hotspot tracks (quasilinear chains of seamounts, ridges, and other volcanic structures) provide important records of plate motions, as well as mantle geodynamics, magma flux, and mantle source compositions. The Tristan-Gough-Walvis Ridge (TGW) hotspot track, extending from the active volcanic islands of Tristan da Cunha and Gough through a province of guyots and then along Walvis Ridge to the Eten

Microplastics in freshwater systems : A review of classification, sources, and environmental impacts

The globally increasing contents of microplastics (MP) in ecosystems have become a serious environmental problem with far-reaching and at present unpredictable consequences for both aquatic life and human well-being. Until recently, most research on MP focused on marine ecosystems. Research on the occurrence of MP has lately started to focus on freshwater environments. This comprehensive and criti

Land use transformations in the Brazilian Savanna : A decade of soil erosion and runoff measurements

Changes in land cover and land use (LULC) are one of the main drivers of erosion and runoff. How ever, most research has relied on short-term observations and only focused on one or two land cover types. We investigated the long-term trade-off between common agricultural land covers (sugarcane, pasture, and soybean), runoff, and soil loss rates. We compared these to native forest (wooded Cerrado)

Assessment of drinking water quality and identifying pollution sources in a chromite mining region

Water sources near mining regions are often susceptible to contamination from toxic elements. This study employs machine learning (ML) techniques to evaluate drinking water quality and identify pollution sources near a chromite mine in Iran. Human health risks were assessed using both deterministic and probabilistic approaches. Findings revealed that concentrations of calcium (Ca), chromium (Cr),

Production of bio-based adipic acid using a combination of engineered Pseudomonas putida strains

Adipic acid is an industrially important dicarboxylic acid and an essential precursor in the synthesis of Nylon-6,6. Due to the environmental impact associated with the current synthetic methods for Nylon-6,6 production, greener alternatives based on renewable and bio-based feedstocks are needed. In the present study, the potential of two Pseudomonas putida strains engineered for muconic acid

Toward low-carbon ways of life : The cultural politics of contesting aeromobility

För snart ett decennium sedan startade en intensiv debatt om flygets klimatpåverkani svenska medier. I dess kölvatten har en social rörelse för minskat flygresande tagitform – flygfrittrörelsen. Den består av individer och organisationer som tillsammansengagerar sig för minskat flygresande, dels genom att delta i kampanjer och annatpåverkansarbete, och dels genom att själva avstå flygresande.Min aThe need for demand-side climate solutions is increasingly recognized in science and society. Such solutions imply that demand for goods and services is targeted either via changes in the use of infrastructure and technology or via cultural changes in consumption and lifestyle among the global affluent. In this thesis, I explore how to enable cultural change around affluent overconsumption through

Nutritional Composition of Six Amaranth (Amaranthus caudatus) Andean Varieties

Amaranthus caudatus is a nutrient-rich Andean pseudocereal with wide genetic variability. Six productive varieties (Oscar Blanco, Pucara, Tomina, Cotahuasi, Barbechos, and Guindo Criollo) were compared by proximate, mineral, and fatty acid composition. The proximal content showed certain singularities in the varieties. Barbechos and Guindo Criollo stood out for their fat content (9.50% and 9.01%,

Talking The Talk but Not Walking the Walk : Is the Use of Sustainability Keywords in IS/IT Job Ads “Greenwashing”?

This paper explores the intersection of corporate sustainability and recruitment perspectives in Swedish companies, examining the use of one hundred and seven sustainability keywords in more than 230 000 IS/IT job ads collected from the Swedish Public Employment Service. The study emphasizes the pressing need for a new breed of computing professionals to address environmental challenges and climat

AACC Approved Methods Technical Committee Report: Crack Resistance and Translucency Determination of Paddy Rice Kernels Using the PaddyCheck Instrument

Physical properties such as break resistance, chalkiness, and size dimensions are very important for grading rice quality. Today, most of the methods used for determining these properties are performed manually, making them both time-consuming and, to some extent, subjective, which, in turn, can affect the determination of rice quality and, thereby, the price. A collaborative study was conducted b

Progression to type 1 diabetes in the DPT-1 and TN07 clinical trials is critically associated with specific residues in HLA-DQA1-B1 heterodimers

AIMS/HYPOTHESIS: The aim of this work was to explore molecular amino acids (AAs) and related structures of HLA-DQA1-DQB1 that underlie its contribution to the progression from stages 1 or 2 to stage 3 type 1 diabetes.METHODS: Using high-resolution DQA1 and DQB1 genotypes from 1216 participants in the Diabetes Prevention Trial-Type 1 and the Diabetes Prevention Trial, we applied hierarchically orga

Fabrication and Electrocatalytic Evolution of Alkali-Free CoNb2O6 Thin Films for Water Oxidation via Polyoxoniobates

Fabrication of CoNb2O6 thin films was possible through spin-coating an alkali-free, aqueous solution of a polyoxoniobate ([Nb10O28]6-, Nb10) and a cobalt nitrate (Co(NO3)2), followed by annealing. The results showed that depending on the calcination conditions, minor phases of unreacted Co3O4 and β-Nb2O5 may form alongside the columbite CoNb2O6 phase. However, optimizing the calcination conditions
