  1. 1. The Hydrodynamics of Waterjet/Hull Interaction

    Författare :Arash Eslamdoost; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; trim angle; vena-contracta; transom clearance; net thrust; waterjet hull interaction; waterjet propulsion; capture area; exit drag; non-linear free-surface; intake drag; gross thrust; sinkage; streamtube; RANS; thrust deduction; potential flow; VOF;

    Sammanfattning : The objective of the present investigation is to explore the physics behind the waterjet/hull interaction, and in particular the negative thrust deduction often reported in the semi-planing speed range. Another objective is to propose a validated numerical technique for computing the hydrodynamics of waterjet-driven hulls. LÄS MER

  3. 2. Multi-Agent Mission Planning and Execution for Small Autonomous Underwater Vehicles

    Författare :Özer Özkahraman; Petter Ögren; João Tasso de Figueiredo Borges de Sousa; KTH; []

  4. 3. CO2 Capture through Integration of Aqueous and Immobilized Deep Eutectic Solvents

    Författare :Sahar Foorginezhad; Xiaoyan Ji; Hailong Li; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Ionic liquid; Deep eutectic solvent; Immobilization; Slurry.; Energiteknik; Energy Engineering;

    Sammanfattning : The growing global concern over rising CO2 emissions and its significant impact on climate change highlight the urgent need for efficient CO2 capture technologies. Among the array of techniques employed for this purpose, chemical absorption stands out, characterized by high capture capacity, promising efficiency, and versatile applicability. LÄS MER

  5. 4. Group A Streptococci; Epidemiology and Genetics of Antibiotic Resistance

    Författare :Aftab Jasir; Avdelningen för medicinsk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; typing; epidemiology; M protein; emm gene; erythromycin; tetracycline; macrolides; streptococci; antibiotics; mykologi; virologi; bakteriologi; Mikrobiologi; mycology; virology; bacteriology;

    Sammanfattning : Group A streptococci (GAS) cause throat and skin infections, severe invasive diseases as well as the non-suppurative complications acute rheumatic fever and glomerulonephritis. GAS have retained susceptibility to betalactam drugs, but resistance to alternative antibiotics is of concern. LÄS MER

  7. 5. Host-Pathogen Interactions in Pseudomonas aeruginosa Invasive and Respiratory Tract Infection

    Författare :Magnus Paulsson; Malmö Klinisk mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pseudomonas aeruginosa; vitronectin; Respiratory tract infections; Innate Immunity; outer membrane vesicles; outer membrane proteins; beta-lactamase; ciprofloxacin; combination treatment; bacteraemia; Complement escape;

    Sammanfattning : Pseudomonas aeruginosa is an opportunistic bacterium that causes debilitating infections when the immune defence is compromised. It possesses an arsenal of virulence traits to colonize most compartments of the body and is often highly resistant against commonly used antimicrobial drugs. LÄS MER
