  1. 11. The effects of management practices and environmental variables on the biodiversity of Nardus grasslands in the national park Hohe Tauern, Austria

    University essay from SLU/Dept. of Ecology

    Author : Rebecca Paulina Dörner; [2023]
    Keywords : biodiversity; Nardus stricta; Nardus grassland; national park Hohe Tauern; East Tyrol; alpine pastures;

    Abstract : Introduction. A large part of the biodiversity of the Alps is linked to an interaction between the natural environment and traditional land-use practices. This study focuses on the priority habitat type of species rich Nardus grasslands (Natura 2000 Code 6230*), which is endangered, but continues to thrive in extensively managed subalpine pastures.

  3. 12. Effects of soil factors on pioneer bryophyte species composition

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Dora Mijić; [2023]
    Keywords : Biology and Life Sciences;

    Abstract : Bryophytes play a significant role in various ecological processes, including soil succession and colonization after disturbances. Although they are commonly believed to take up nutrients from soil solutions rather than the soil itself, the influence of soil on their growth and distribution is evident from previous studies.

  4. 13. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

    University essay from Örebro universitet/Institutionen för hälsovetenskaper

    Author : Gabriella Persson; [2023]
    Keywords : Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

    Abstract : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). READ MORE

  5. 14. Deep Learning Based Detection, Quantification, and Subdivision of White Matter Hyperintensities in Brain MRI

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Inna Fryckstedt; [2023]
    Keywords : white matter hyperintensities; white matter lesions; deep learning; machine learning; DL; ML; MRI; iNPH;

    Abstract : White matter hyperintensities (WMH) are commonly found as bright regions in brain MRI images in older individuals. They are associated with various neurological and vascular diseases, such as stroke, dementia, and cardiovascular disorders. READ MORE

  6. 15. Effects of climate and land-use change on retention of semi-natural grassland plant species : A landscape study in southern and central Sweden

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)
