  1. 1. Adapting the bundle of capillary tubes model (BCTM) for vertical soil solute transport modelling

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Martin Larsson; [2019]
    Keywords : soil solute vertical transport modelling vadose; Earth and Environmental Sciences;

    Abstract : This study explores an approach for adapting the bundle of capillary tubes soil model for vertical soil solute transport modelling. The soil is split into thin layers allowing vertical water flow between capillaries of differing width with concomitant advective flow of solutes. Diffusion is included to improve realism. READ MORE

  2. 2. Experimental assessment of fluid hammer prediction algorithms

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Jessica Kihlström; [2018]
    Keywords : ;

    Abstract : Fluid hammer is a problem, which may lead to catastrophic consequences and many engineers have a deficiency in competence when it comes to its prediction. This study´s objective is to assess various fluid hammer prediction models, to evaluate how substantial pressure thrusts would affect a system and to verify the analytical results toward experimental data.

  3. 3. New methods for seed potato production: an investigation into the production and farmer uptake of mini tubers in South Africa

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

    Author : Alba Sáez Fernández; [2018]
    Keywords : mini-tubers; Chlorophyll fluorescence; Leaf Area Index; small-scale farming;

    Abstract : Potatoes are by far the most produced fresh vegetable crop in South Africa. Remarkably, potato sales represent more than 30% of the turnover in the Fresh Produce Markets (FPM). READ MORE

  4. 4. Evaluation of current welding robot and improvement proposals for future use

    University essay from KTH/Marina system

    Author : Joakim Nilsson; [2018]
    Keywords : ;

    Abstract : Welding of elements, a heat exchanging component, is one of the most essential processes during the manufacturing of Tubel evaporators. Weld joints consists of fillet welds of thin tubes against a plate on one end, and on the other end against a thicker pipe with entry holes for the tubes. READ MORE

  5. 5. Sequence analyses of novel Potato virus YNTN and resistance-breaking PVYO isolates from Sweden

    University essay from SLU/Department of Plant Biology (from 140101)

    Author : Asmaa Youssef; [2017]
    Keywords : defective RNA molecules; D-RNAs; phylogeny; potato tuber necrotic ringspot disease; potyvirus; PVYNTN; PVY strains; recombination;

    Abstract : Potato virus Y (PVY) is a devastating potato pathogen affecting potato (Solanum tuberosum) production worldwide. In the last few decades, novel PVY recombinant genotypes have been described to induce severe symptoms in numerous potato cultivars. READ MORE
