  1. 21. Jämförelse mellan olika jordbearbetningsmetoder vid etablering av vårkorn

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

    Author : Henrik Frisk; [2022]
    Keywords : plog; kultivator; tallrikskultivator Carrier; ultragrund; vårkorn; etablering; skotträkning; axräkning; tilling; spring barley; reduced tilling;

    Abstract : I dagens jordbruk effektiviseras allt för att spara tid, pengar och miljö, men samtidigt bedriva en effektiv odling som ger hög avkastning. Det är därför intressant att studera vilken jordbearbetningsmetod som är effektivast för att få en bra etablering samt en bra axbildning, som bygger hög skörd. READ MORE

  3. 22. Paleomagnetic and Thermomagnetic Studies on Rock Samples from COSC - 1 Drilling Project

    University essay from Uppsala universitet/Geofysik

    Author : Wanyi Li; [2022]
    Keywords : Scandinavian Caledonides; remanent magnetization; AF demagnetization; temperature dependent magnetic susceptibility; Skandinaviska Kaledoniderna; remanent magnetism; växelfältsavmagnetisering; temperaturberoende av magnetisk susceptibilitet;

    Abstract : The COSC-1 borehole located in the Lower Seve nappe of the Central Scandinavian Caledonides is intended to study the tectonic evolution of the Paleozoic orogen. The drilling project reached a depth of 2495.8m and obtained samples from different lithologal units of mica schist, amphibolite, gneiss, and mylonitic gneisses. READ MORE

  4. 23. The Biogeographical Extent and Global Synchronicity of the Late Miocene Reticulofenestra pseudoumbilicus Paracme

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Joseph Asanbe; [2022]
    Keywords : late Miocene; biogenic bloom; nannofossil biostratigraphy; paleo-productivity; Reticulofenestra size variation;

    Abstract : Previous biostratigraphic studies in the Indian Ocean, equatorial Pacific, Atlantic Ocean and the Caribbean Sea document the temporal disappearance of Reticulofenestra pseudoumbilicus in the late Miocene (Tortonian age). This interval has been subsequently defined as the R. pseudoumbilicus paracme. READ MORE

  5. 24. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Eduardo Garcia Cañas; [2022]
    Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

  6. 25. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs

    University essay from Linköpings universitet/Fordonssystem

    Author : Mohamed Faraj; Max Olsson; [2022]
    Keywords : Vehicle Propulsion Systems; Electrical powertrain; Modeling; Simulation; Deterministic dynamic programming; AMESim;

    Abstract : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. READ MORE
