1. Diversity of thermostable DNA enzymes from Icelandic hot springs
Abstract : The diversities of bacteria as well as thermostable DNA enzymes in Icelandic hot springs were studied using different techniques. First of all the bacterial diversity of different microbial mats as well as sediment samples was described by using both molecular methods and cultivation methods. READ MORE

2. Phylogenetic characterization of microbial mats and isolation of Thermus spp. and sulfur-oxidizing bacteria from Icelandic hot springs
Abstract : Until recently, the only way to describe microbial communities was by cultivation. This is a major obstacle because typically only a small fraction of the microbes can be cultivated by standard techniques. However, the use of rRNA and molecular phylogenetic techniques has allowed us to bypass this limitation. READ MORE

3. Moisture Influence on Structural Behaviour of Pavements : Field and Laboratory Investigations
Abstract : The structural behaviour of pavements in cold regions can considerably be affected by seasonal variation in environmental factors such as temperature and moisture content. Along with the destructive effect of heavy traffic loads, climatic and environmental factors can considerably contribute to pavement deterioration. READ MORE

4. Antimicrobial potential of Geobacillus sp. ZGt-1 isolated from Zara hot spring in Jordan : Piecing the puzzle of the antagonistic activity of a novel bacterial strain
Abstract : The problem of antibiotic resistance is rising continuously, creating a warning signal that calls for finding alternatives. Not only that, but there is also a rising demand for natural food preservatives. The pharmaceutical and food industry sectors are working on fulfilling these needs. This thesis is exploring possible solutions to these issues. READ MORE

5. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification
Abstract : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. READ MORE
