  1. 1. Carabids as weed seed control agent : impact of soil cultivation on carabid weed seed regulation

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Ellen Dahlgren; [2023]
    Keywords : weed seed predation; weed seed bank regulation; weed seed predation strength; seed predation strength; carabid beetles; tillage; piecewise structural equation model;

    Abstract : As weed seed predators, carabid beetles can regulate the weed seed bank within agricultural fields. Little is anyhow known about how weed seed bank regulation by carabids is affected by different tillage treatments with decreasing intensity, why this was here examined. READ MORE

  3. 2. Assessing the effect of Fusarium graminearum inoculation on the root structure of Swedish winter wheat cultivars (Triticum aestivum

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Fayez Altabbaa; [2022]
    Keywords : Fusarium graminearum; conidium suspension; hypha agar plug; root architecture traits; root cellar structure traits; shoot traits; genotypes;

    Abstract : Several diseases attack the wheat crop and reduce the yield, such as root disease, which causes a tremendous loss in wheat production. Root rot has a variety of causal agents, such as nematodes, viruses, and bacteria, but the most common pathogens causing wheat root rot are oomycetes and fungi. READ MORE

  4. 3. Impact loads on the self-elevating unit during jacking operation

    University essay from

    Author : Viktor Daun; Fredrik Olsson; [2019-07-03T13:28:32Z 2019-07-03T13:28:32Z 2014]
    Keywords : Farkostteknik; Vehicle Engineering;

    Abstract : The renewable energy resource of offshore wind is believed to have a great potential in playing an essential role on the future energy market in Europe, but there are complications such as harsh weather and low accessibility. To manage this, most offshore wind turbines of today are installed and maintained using self-elevating units (SEUs). READ MORE

  5. 4. Dynamic Design of Bridges on High-Speed Railway Lines

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Author : Felicia Nilsson; Filippa Dahl; [2019]
    Keywords : High-speed railway bridges; bridge-train resonance; structural dynamics; modal dynamics; time stepping; soil-structure interaction; finite element method; BRIGADE Plus; Technology and Engineering;

    Abstract : In recent years, high-speed railway has been on the upswing in the public debate, as Swedish authorities have affirmed the plans of a high-speed corridor connecting Stockholm, Gothenburg and Malm¨o. The track speed limit is not fully determined, but will be in the range of 250-320 km/h. READ MORE

  6. 5. Train Induced Vibration Analysis of an End-frame Bridge : Numerical Analysis on Sidensjövägen

    University essay from KTH/Bro- och stålbyggnad

    Author : Niklas Wiberg; Jasmin Halilovic; [2018]
    Keywords : Accelerations; Dynamics; End-frame bridge; FE-modeling; Frequency response function; High-speed railway; Soil structure interaction; Train induced vibrations; 2D 3D;

    Abstract : Higher speeds and higher capacity will cause the Swedish rail network to be exposed to disturbing dynamic effects. Higher speeds cause higher vertical acceleration levels of the bridge deck. In this thesis, a numerical analysis of a three span end-frame bridge subjected to train induced vibrations is performed.
