  1. 1. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Gila van den Eijnde; [2023]
    Keywords : Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

    Abstract : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. READ MORE

  3. 2. Drivers and Barriers for Biochar Deployment in Swedish Agriculture : a Multi-Level Perspective on Sustainability Transitions

    University essay from SLU/Department of Molecular Sciences

    Author : Danielle Jansen; [2023]
    Keywords : Agriculture; Socio-technical transitions; Multi-level perspective;

    Abstract : There are several sustainability challenges (e.g., environmental degradation, biodiversity loss, and food insecurity) that agro-food systems face. Simultaneously, agriculture is a major contributor to greenhouse gas emissions. READ MORE

  4. 3. Impact of the autoencoder-based FINTA tractogram filtering method on brain networks in subjects with Mild Cognitive Impairment

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Teodor Pstrusiński; [2023]
    Keywords : Tractography; Autoencoder; diffusion MRI; Filtering; Graph; Connectome; Traktografi; Autoencoder; diffusions MRT; Filtrering; Graf; Konnektom;

    Abstract : Diffusion Magnetic Resonance Imaging (dMRI) is a method for measuring molecular diffusion in biological tissue microstructure. This information can be used to predict the location and orientation of white matter fibers in the brain, a process known as tractography. READ MORE

  5. 4. Deterministic Nanopatterning of Graphene Using an Ion Beam

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Henrik Bruce; [2022]
    Keywords : nanofabrication; lithography; nanopatterning; nanoporous graphene;

    Abstract : Graphene features a unique combination of exceptional properties and has emerged as one of the most promising nanomaterials for a variety of applications. The ability to structurally modify graphene with nanoscale precision enables the properties to be further extended. READ MORE

  6. 5. Modelling of gene regulatory and spatial mechanisms which pattern the early human neural tube

    University essay from Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

    Author : Fredrik Bertilsson; [2022]
    Keywords : Biophysics; systems biology; gene regulatory networks; neural tube; isthmic organizer; midbrain-hindbrain boundary; WNT; FGF; morphogens; reaction-diffusion; finite-difference; 3D modelling; Physics and Astronomy;

    Abstract : Tissue patterning during development is thought to be driven largely by gene regulatory responses to spatial gradients of molecular signals, known as morphogens. In this thesis, early patterning of the human neural tube is studied using two different gene regulatory network models. READ MORE
