  1. 1. Evaluation of liver and fur copper concentrations in dairy cows : in relation to dietary intake of copper and molybdenum

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Ida Hansen; [2023]
    Keywords : copper; copper status; dairy cow; fur; liver; molybdenum; ruminant;

    Abstract : Koppar (Cu) har en avgörande roll i flera viktiga metaboliska funktioner och är en essentiell mineral för idisslare. Kopparbrist kan resultera i ett flertal problem som påverkar djurets hälsa och produktion, men även överutfodring av Cu kan resultera i allvarliga kliniska symptom på grund av ackumulering av Cu i levern.

  3. 2. Symmetric Lorentzian polynomials

    University essay from KTH/Matematik (Avd.)

    Author : Daniel Qin; [2023]
    Keywords : symmetric polynomials; Lorentzian polynomials; matroids; symmetriska polynom; lorentziska polynom; matroid;

    Abstract : In 2020, Huh, Matherne, Mészáros, and St. Dizier established the Lorentzian property of normalized Schur polynomials and conjectured the Lorentzian nature of other Schur-type symmetric polynomials. READ MORE

  4. 3. A practical framework for the electric vehicle routing problem

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Johan Hellmark; [2022]
    Keywords : Technology and Engineering;

    Abstract : The routing of a delivery fleet is a classical optimization problem, known as the vehicle routing problem (VRP), which can heavily impact the quality of a logistic distribution process. Historically, the VRP formulation has mainly included internal combustion engine vehicles (ICEVs). READ MORE

  5. 4. Active Learning for Solving Expensive Optimization Problems

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Siwei Fu; [2022]
    Keywords : ;

    Abstract : Many practical engineering and computer science problems can be translated into a global otimization problem where the task is to find the best (optimal) vector 𝒙𝒙∗ that gives the smallest possible function value 𝑓𝑓 = 𝑓𝑓(𝒙𝒙∗) for some function 𝑓𝑓() of interest. Often the function 𝑓𝑓() is expensive in the sense that it cannot be easily evaluated computationally or experimentally in terms of time and/or resources required. READ MORE

  6. 5. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Frederika Klaus; [2022]
    Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE
