  1. 1. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 2. Relations between intracellular pH and gamma-aminobutyric acid levels in tea (Camellia sinensis) leaves, after two types of anaerobic treatment

    L3-uppsats, SLU/Dept. Of Plant Biology

    Författare :Mingmin Tao; [2023]
    Nyckelord :tea leaves; intracellular pH; gamma-aminobutyric acid; glutamate; decarboxylase; fluorescent dye;

    Sammanfattning : Tea (Camellia sinensis) is one of the three major non-alcoholic beverages in the world. In Gabaron tea, the levels of γ-aminobutyric acid (GABA) are more than 1.3 mg/g. In the human body, GABA lowers blood pressure and cholesterol levels. LÄS MER

  4. 3. Automated High-Temperature Pressure Sensor Verification and Characterization

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Algirdas Bartkevicius; [2023]
    Nyckelord :Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Sammanfattning : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. LÄS MER

  5. 4. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Elias Aretorn; [2023]
    Nyckelord :CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

    Sammanfattning : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. LÄS MER

  7. 5. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Filip Palm; [2022]
    Nyckelord :Oceanbird; Sail pressure; KTH; pressure sensor system; Environment; Oceanbird; tryckmätningssystem; miljö; KTH; tryckmätning segel;

    Sammanfattning : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. LÄS MER
