1. 6. Quantifying liquid food waste : levels of liquid coffee waste, its causes and barriers and drivers for quantification in the Swedish food service sector

   Master-uppsats, SLU/Department of Molecular Sciences

   Författare :Rosa Hellman; [2024]
   Nyckelord :sewage food waste; beverage waste; direct measurement; hospitality; restaurant; serving waste; food waste cause;

   Sammanfattning : Food waste is a waste of resources required throughout the entire supply chain, leading to environmental impacts that could have been avoided. Coffee has a relatively high environmental impact partially due to the high consumption. To identify levels and sources of food waste, and consequently prevent it, quantification is used. LÄS MER

3. 7. Machine learning for molecular property prediction and drug safety

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :Kinga Jenei; [2023-10-23]
   Nyckelord :Molecular property prediction; Acid dissociation constant; pKa; Machine learning; Graph Neural Networks; Molecular descriptors; Drug Discovery;

   Sammanfattning : Utilizing machine learning methods for the prediction of acid dissociation (pKa ) values of compounds holds great significance, as pKa is an important parameter, optimized frequently in drug discovery. Accurate prediction of pKa values could potentially provide valuable insights on other molecular properties and thereby support compound design. LÄS MER

4. 8. The Valeriana officinalis aggregate in Sweden. A preliminary study.

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Daniel Bäck; [2023-06-30]
   Nyckelord :;

   Sammanfattning : Common valerian (Valeriana officinalis L.) is a species of flowering plants native to Europe, the roots of which have been used in folk medicine for centuries. But due to high diversity in morphology and chromosome numbers, different populations in V. LÄS MER

5. 9. Systematics and the evolution of flower symmetry of Posoqueria (Rubiaceae)

   Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Författare :Sebastián Giraldo Gómez; [2023-06-14]
   Nyckelord :Posoquerieae; Cinchonoideae; Ixoroideae; Dialypetalanthoideae; Angiosperms 353; target capture; Hybpiper; Pollen Catapult Mechanism.;

   Sammanfattning : The genus Posoqueria is a Neotropical group of shrubs and trees in the coffee family Rubiaceae. Posoqueria is phylogenetically poorly understood and presents several internal taxonomical difficulties. LÄS MER

7. 10. Morphological study of PS/PMMA-matrix on glass, related to vapour pressure, mass-fraction, and size

   Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

   Författare :Gustav Larsson; [2023]
   Nyckelord :organic solar cells; polymer; morphology; film; AFM;

   Sammanfattning : The objective of this study is to observe how changing amount or ratio between dried mixes of poly-methyl-methacrylate and poly-styrene change the surface appearance, and how the results might inform future design of Organic photovoltaic cells, whom are based on polymer mixtures and heavenly dependent on the arrangement of polymers. An atomic force microscope was used on glass surfaces coated in a poly-methyl-methacrylate/poly-styrene matrix and dried from either dichloromethane or ethyl-acetate to determine surface appearance.
