  1. 31. Nitrogen legacies in agricultural catchments : an analysis of 170 years of nitrogen legacies data in four Swedish agricultural catchments

    University essay from SLU/Dept. of Soil and Environment

    Author : Laura-Ainhoa Prischl; [2023]
    Keywords : nitrogen mass balance; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture;

    Abstract : Despite the enforcement of legislation and application of measures, nitrogen (N) levels continue to be high in streams. One of the reasons for the low N reduction, is the legacy accumulation of N. READ MORE

  3. 32. The potential future travelers on the North Bothnia Line : Sävar, Robertsfors and Bureå

    University essay from Umeå universitet/Institutionen för geografi

  4. 33. Condition-based Estimation of Ambulance Travel Times

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Lucas Kylberg; [2023]
    Keywords : Travel time estimation; Travel time prediction; Emergency vehicles;

    Abstract : Travel time estimation can be used in strategical distribution of ambulances and ambulance stations. A more accurate travel time estimation can lead to a better distribution of these ambulance sites. External factors such as weather and traffic conditions can affect the travel time from a starting location to a destination. READ MORE

  5. 34. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Camilla Lane; [2023]
    Keywords : Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

    Abstract : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

  6. 35. Heuristic Clustering Methods for Solving Vehicle Routing Problems

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Georgios Nordqvist; Erik Forsberg; [2023]
    Keywords : optimization; vehicle routing problem; sweep clustering; k-means clustering; hierarchical clustering;

    Abstract : Vehicle Routing Problems are optimization problems centered around determining optimal travel routes for a fleet of vehicles to visit a set of nodes. Optimality is evaluated with regard to some desired quality of the solution, such as time-minimizing or cost-minimizing. READ MORE
