1. 1. The intraspecific drought tolerance of Betula pendula Roth. : ecotypic aptitude as tree selection criteria for the urban landscape

   University essay from SLU/Dept. of Plant Breeding (from 130101)

   Author : Simon Hannus; [2021]
   Keywords : Betula pendula; clinal variation; drought tolerance; ecosystem services; ecotypes; potential evapotranspiration; turgor loss point; urban forestry; urban resilience; urban tree selection;

   Abstract : The ecosystem services provided by urban trees are substantial contributors to the quality of urban living, and their environmentally regulating capabilities are increasingly regarded as integral in order to efficiently secure urban resilience, by ameliorating the human and material impacts of extreme weather events. However, current trends of urban development presents challenges of how to preserve urban greenery ecosystem functioning, particularly in light of the ongoing climate change; which also has brought forth the importance of taxonomically diverse urban forests, to mitigate risks of catastrophic tree loss associated with these conditions.

3. 2. Fluid/Material Coupled Numerical Analysis of Single Bubble Collapse Near a Pit on a Wall

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Daiki Makii; [2020]
   Keywords : Bubble Dynamics; Cavitation Erosion; Numerical Analysis; Fluid Material Coupled Numerical Method; Homogeneous Model; Elastic Body Material; Erosion Pit;

   Abstract : In order to elucidate the progression mechanism of cavitation erosion, the behaviors of a single cavitation bubble collapse near a pit on a wall and both the resulting pressure wave in fluid and stress wave in material are investigated in detail. To find out the mechanism of cavitation erosion, many experimental studies on the bubble collapse behavior near a flat rigid wall and the resulting material damage have been conducted so far.

4. 3. Investigation of immunomodulatory properties of anti-secretory factor in experimental brain tumor models

   University essay from Lunds universitet/Läkarutbildningen

   Author : Hanin Fabiana El-Sabee; Amanda Peetre; [2020]
   Keywords : Antisecretory factor; Immunomodulation; Glioblastoma; Medicine and Health Sciences;

   Abstract : Introduction: Glioblastoma is the most aggressive form of primary brain tumor in adults. Current treatment including chemotherapy poses a limitation due to consequences of systemic toxicity. Further studies for alternative, multimodal treatments are necessary. Antisecretory factor is an endogenous protein. READ MORE

5. 4. Biolayer development in a slow sand filter in Ghana : Designing a filter that is benefiting the biolayer development under local conditions

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Linda Hummerhielm; [2017]
   Keywords : slow sand filter; biolayer; development; långsamfilter; biofilm; utveckling;

   Abstract : In 2015, the United nations presented the 17 Global Goals that would put an end to extreme poverty, inequality and climate change by 2030. One of these goals was clean water and sanitation. In 2015 1.8 billion people did not have access to clean water. READ MORE

6. 5. Orsaker och erfarenheter om bidöd

   University essay from SLU/Dept. of Ecology

   Author : Olof Engle; [2016]
   Keywords : bidöd; biförluster; pollineringsbehov;

   Abstract : Domesticeringen av honungsbin påbörjades för mer än 7 000 år sedan. Från början hölls honungsbin främst för sin honungs- och vaxproduktion, men började senare även hållas i pollineringssyfte. I och med det industrialiserade jordbrukets intåg växte pollineringsbehovet bland jordbruksgrödor. READ MORE
