Denna studie undersöker hur stressfaktorer påverkar kroppen vid dykning i gruva. Undersökningen genomfördes under en helgs intensivt dykande, för att bestämma lungkapacitet, pulsnivå samt eventuell vätske- och viktförlust hos dykarna. Testerna bestod av vägning, spirometritester …
Detektion av bakterier och svamp med <em>in situ</em> hybridisering och immunofluorescens
Bakgrund: Det är viktigt att främja barns fysiska aktivitet, eftersom det leder till många positiva hälsoeffekter. Tyvärr är många små barn idag inaktiva och når aldrig den rekommenderade gränsen på 60 minuters fysisk aktivitet per dag. Syfte: Att beskriva hur fysisk aktivitet …

… algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The …
a study about liming officers opinions about some aspects regarding ecology, economy and organization
… color measurement before liming were considered useful by the liming officers. Fish data were considered reliable, but uncertainties with the parameter were also mentioned. Diatoms were further mentioned as reliable and several liming officers had increased the sampling …
… nine hydro-electric power plants. None of the hydro-electric power plants have fishways so that salmon migrating upstream or downstream may pass. In the current situation, the upward migrating salmon are caught in a fish trap at the most downstream located power plant in …

En vision om att återfå en balans i Östersjön genom att skörda algöverskott och använda biomassan som en framtida råvara.
… problem is spreading towards the coastal zone, which is an important site for fish recreation. By removing the abundance of algae, the nutritional and toxic substances are reduced and the algae biomass can be a future resource for biofuel production.
En jämförande studie av Rysslands och Kanadas agerande i Arktis och Arktiska rådet.
The Arctic region is rich in natural resources such as oil, gas, minerals and fish. Climate change causes the Arctic ice melt, making resource extraction possible as well as opening up new transport routes through the Northwest Passage and the Northeast Passage. This has led to …
Jämförelse av fångstrapportering mellan intervjuer och enkäter gjorda på trollingfiskare samt vädrets påverkan på ansträngning
… the future of the remaining populations remains uncertain. To manage salmonid fishes effectively more knowledge of their ecology throughout their different life-stages is needed. A large part of the Lake Vänern salmonoids lives are spent in the lake, where a mayor mortality …
With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical …
