  1. 6. Thawing, Scaling and Tracking QUintessence in a Phase Space Perspective : and comparisons to the ΛCDM model

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Arvid Ryberg; [2022]
    Keywords : Quintessence; Cosmology; Dark Energy; Astro physics;

    Abstract : This thesis aims to give an introduction to quintessence models as well ascomparing those models with the currently accepted ΛCDM model. We willconsider quintessence in a spatially flat and isotropic Universe and useregular dynamical systems on a bounded three dimensional phase spacewhere we perform numerical calculations. READ MORE

  3. 7. Emissions of nitrous oxide associated with frost killed cover crops

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Felicia Olofsson; [2022]
    Keywords : Nitrous oxide; cover crops; greenhouse gases; freeze-thaw cycles;

    Abstract : Agriculture is responsible for approximately 80% of anthropogenic emissions of the potent and long-lived greenhouse gas nitrous oxide (N2O). N2O emissions from agricultural soils are characterized by high temporal and spatial variability and often peak in short bursts related to events such as precipitation, fertilization and soil thawing.

  4. 8. Laboratory Investigation of Quarry Fines for Use in the Construction Industry

    University essay from KTH/Jord- och bergmekanik

    Author : Antonia Filippidi; [2022]
    Keywords : quarry fines; water content; optimum moisture content; maximum dry density; bearing capacity;

    Abstract : Quarry fines are by-products of the aggregate extraction and productionprocesses. Because such fine material cannot be marketed, it becomes aburden for the aggregate industry, resulting in stockpiles of financiallyunexploited material. READ MORE

  5. 9. Use of a Sperm-Hyaluronan Binding Assay for evaluation of sperm quality in dromedary camels

    University essay from SLU/Dept. of Clinical Sciences

    Author : Anna Kotila-Ioannou; [2022]
    Keywords : Camel Semen; Dromedary camel; Sperm-Hyaluronan Binding Assay; sperm quality analysis;

    Abstract : The objective of this study was to assess the potential of Hyaluronan Binding Assay (HBA) to predict freezability and fertilization capacity of dromedary camel spermatozoa, and to determine if conventional sperm quality parameters and precursor of A-Kinase Anchoring Protein 4 (proAKAP4) values correlate with HBA results. Two semen samples were collected from each of six male camels. READ MORE

  6. 10. Seasonal permafrost subsidence monitoring in Tavvavuoma (Sweden) and Chersky (Russia) using Sentinel-1 data and the SBAS stacking technique

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Ida Rehn; [2022]
    Keywords : InSAR; Sentinel-1; SBAS; Permafrost; Subsidence; Permafrost thaw;

    Abstract : Permafrost deformation is expected to increase due to climatic perturbations such as amplified air and soil temperatures, resulting in permafrost thawing and subsequent subsidence. Palsas and peat plateaus are uplifted ice-rich peat mounds that experience permafrost subsidence. READ MORE
