1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus
Master-uppsats, SLU/Dept. of Forest Mycology and Plant PathologySammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER
2. Temperature Optimum for Biomass Production of two Species of Benthic Diatoms
Kandidat-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Diatoms and other algae can be cultivated and beneficially used in several sectors with applications ranging from nutrient recycling to production of high-valued biomaterials used by the green energy industries, in pharmaceutical products or as food supplements. In this experimental study, the temperature optimum for biomass production was tested for two species of benthic diatoms, Diatoma sp. LÄS MER
3. INFLUENCE OF TEMPERATURE ON BIOMASS AND GROWTH RATE OF BENTHIC DIATOMS
Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskapSammanfattning : Temperature has a significant impact on structure and abundance of microalgal community as well as on physiology (Sheehan et al., 2020). LÄS MER
4. Branching Out with Mixtures: Phylogenetic Inference That’s Not Afraid of a Little Uncertainty
Master-uppsats, KTH/Matematisk statistikSammanfattning : Phylogeny, the study of evolutionary relationships among species and other taxa, plays a crucial role in understanding the history of life. Bayesian analysis using Markov chain Monte Carlo (MCMC) is a widely used approach for inferring phylogenetic trees, but it suffers from slow convergence in higher dimensions and is slow to converge.

5. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations
Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknikSammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER
