  1. 1. The functional anatomy of the crocodilian heart

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Jennifer Karlsson; [2023]
    Nyckelord :Anatomy; Cardiac right-to-left shunt; Cog-teeth-like valves; Crocodilian heart; Foramen of Panizza; Hemodynamics; Left aorta;

    Sammanfattning : Crocodiles are ectothermic, intermittent breathing reptiles with low metabolic rates. Additionally, they are diving animals that can stay submerged for long periods, which poses special demands on their cardiovascular system. The crocodilian heart is four-chambered with completely separated ventricles, making it unique among other reptiles. LÄS MER

  3. 2. Feasibility study of evaporative cooling and toilet flushing using rainwater in a public building

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Claudia Reig Moril; [2023]
    Nyckelord :Rainwater; Evaporative cooling; Toilet flushing; Energy; Water; Feasibility.; Regnvatten; Evaporativ kyla; Toalettspolning; Energi; Vatten; Genomförbarhet.;

    Sammanfattning : The project "Feasibility of evaporative cooling and toilet flushing using rainwater in a public building" combines rainwater harvesting with the evaporative cooling technology and toilet flushing and explores the practicality and viability of implementing this innovative system in the city of Gothenburg, Sweden. This study comprehensively investigates various aspects related to water and energy, and the entire system is computationally modelled using the Equation Engineering Solver (EES) software. LÄS MER

  4. 3. NH Planetary-Scale Circulation in Troposphere and Stratosphere: A Spectral and Dynamical Perspective

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Michael Konrad Schutte; [2023]
    Nyckelord :jet stream; Rossby waves; polar vortex; spectral analysis; dynamic systems theory; sudden stratospheric warmings; strong polar vortex events; jetström; Rossbyvågor; polär virvel; spektralanalys; dynamisk systemteori; plötsliga stratosfäriska uppvärmingar; starka polvortexhändelser;

    Sammanfattning : Dynamic Systems Theory (DST) and spectral analysis are employed to study the tropospheric jet stream and the stratospheric polar vortex. The objective is to investigate the relationship between Rossby wave activity and inverse persistence and dimensionality of geopotential height at 250 hPa and 10 hPa, as these two dynamical indicators are expected to show a characteristic behavior of Rossby wave harmonics.

  5. 4. High tide flooding in near future projections for popular travel destinations

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :David Ebert; [2023]
    Nyckelord :Physical Geography and Ecosystem analysis; High tide flooding; Projections; Adaptation and mitigation strategies; Lunar precession; Nodal cycle; Cycle of lunar perigee; Earth and Environmental Sciences;

    Sammanfattning : High tide flooding (HTF) is becoming more common in coastal regions of the United States, although this phenomenon remains largely undocumented in published literature from other parts of the world. No matter the emissions scenario over the next decades, sea level rise (SLR) is projected to continue worldwide until at least the end of the 21st century, continually pushing the frequency and severity of HTF.

  7. 5. ASSESING HISTORICAL (1926-1996) NEAR-SURFACE WIND SPEED VARIABILITY ACROSS SWEDEN

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jessika Lönn; [2022-06-27]
    Nyckelord :Near-surface wind speed; teleconnection patterns; Sweden; stilling; reversal;

    Sammanfattning : Homogenized near-surface wind speed (NSWS) series of 7 stations from rescued observational journals have been analyzed for the 70-years time-period 1926-1996 to investigate past changes and variations across Sweden. During the whole period, there has been a statistically significant (at p < 0.05) decreasing trend of -0.11 m s-1 decades-1. LÄS MER
