Är en sur vattenmiljö dålig för bakterier? Bakterier finns överallt på vår planet och är bland annat viktiga för nerbrytningsprocesser i naturen. De bakterier som klassificeras som heterotrofa livnär sig genom att bryta ner döda växt-och djurdelar och omvandla detta till energi. I sjöar och vattendrag utgör dessa bakterier en central del, då de kan utnyttja resurser som är otillgängliga för andraAbstract The environmental pH is an important factor affecting bacterial physiology and function as well as community composition in soil and marine ecosystems. However, studies of the effect of pH on bacterial function in limnic systems have been scarce. Considering studies in soil where it has been conclusively confirmed that bacterial growth rates (μ) are considerably lower in a low pH environ

Overexpression or mutation of α-synuclein have been identified as the direct cause of cell loss and dominant inherited PD, although the mechanism i

Christman, Garvey, Propper och Phaneuf fann 2003 att horisontella saccadiska ögonrörelser förbättrade det episodiska minnet. Effekten har sedan dess dokumenterats i flera andra icke-visuella kognitiva uppgifter, så som kreativitet och interhemisfärisk processering. Syftet med denna uppsats var att undersöka de horisontella saccadiska ögonrörelsernas påverkan på arbetsminne och källminne. Fjorton d

Sammanfattning Vi har gjort en kvalitativ studie och intervjuat individer med en tidigare missbruksproblematik och kriminellbakgrund. Alla utom en av intervjupersonerna har deltagit i ett 12-stegsprogram. Det finns hjälp att få som missbrukare genom behandling, men det är ändå inte alla som klarar av att sluta fast den hjälpen finns. Det är viktigt och intressant att undersöka varför det är så.

All of the interviewees have a background as criminals and addicts and three of them have participated in twelve-step program. There is treatment that is intended to support and help addicts, but it's still not all that manage to get out of their addiction. That makes it important and interesting to

Abstract We studied the effects of UV-A radiation and predatory fish on mantle pigmentation of freshwater snails Radix balthica. The results showed that UV radiation and fish chemical cue induce larger ratios of pigmented area on mantle, respectively and when combined. UV radiation and predatory fish chemical cue seem to affect mantle pigmentation independently. The ratios (0~100%) of pigmented ma

The Influence of Intergenics in an Important Environmental Cycle As we step forward into the future there is increasing attention toward our impact on the planet and specifically of late debate, our climate. With the carbon dioxide (CO2) in our atmosphere rising at a quick pace and the ocean’s acidity increasing, largely due to the industrial revolution, what environmental influences will we be l
