1. Particle image velocimetry in practice
Sammanfattning : Experimental fluid mechanics has for a long time been used to visualize flow phenomenon. An early pioneer was Ludwig Prandtl who used aluminum particles in water flumes to describe the flow in a qualitative manner. In line with the rapid development of Computational Fluid Dynamics, CFD, the need for new validation tools has increased. LÄS MER
2. From green to yellow : a leaf story
Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER
3. Physiological integration and morphological plasticity in extensive clonal plants
Sammanfattning : Clonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. LÄS MER
4. Stress Related Emissions of Norway Spruce Plants
Sammanfattning : The interactions between plants and insects are mediated by volatile molecules. Plants respond to stress by biosynthesis of chemical substances which can deter invading insects or pathogens. Some of these substances are volatile and are emitted to the surroundings and may attract or repel insects. LÄS MER
5. A Browning process : The case of Dar es Salaam city
Sammanfattning : The study is about how green spaces and structures of Dar es Salaam city, quantitatively and qualitatively, are browning out. It also tries to explore the different reasons behind the browning tendency, and what it means to the function of the city and to the daily form of life of the inhabitants. LÄS MER
