  1. 1. Effekter av klimatförändringar på växtplankton i subarktiska och alpina sjöar

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Matilda Lundström; [2019]
    Keywords : Fosfor; Växtplanktonbiomassa; Diversitet; Oligotrofiering; Temperatur;

    Abstract : The aim of this report was to determine how the climate change affects the ecosystems in alpine and subarctic lakes in Sweden. This was done by analyzing data from environmental monitoring of 14 subarctic and alpine lakes that was part of the national time-series lake monitoring program. READ MORE

  2. 2. Lakes are browner in the south than in the north of Sweden despite similar levels of dissolved iron

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Fredrik Lindgren; [2019]
    Keywords : Brownification; DOC; dissolved iron; humic lakes; sulphur deposition; absorbance; climate change;

    Abstract : During recent decades many lakes have become browner in the northern hemisphere and more specific in Sweden. This process is called brownification. Brownification of lakes makes it more difficult to clean water to drinking water and may have negative ecological effects on biota. READ MORE

  3. 3. Levande begravd : kan klimatförändringar ge mjältbrandssporer nya förutsättningar?

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Johanna Cavell; [2019]
    Keywords : mjältbrand; sporer; klimatförändringar;

    Abstract : Mjältbrand är en dödlig sjukdom som varit känd under en lång tid och som drabbar både djur och människor. En av anledningarna till att mjältbrand är fruktad är bakteriens förmåga att sporulera vid icke gynnsamma förhållanden och persistera i jorden under en lång tid. READ MORE

  4. 4. Neutralization of acidic wastewaters with the use of landfilled Electric Arc Furnace (EAF) high-alloyed stainless-steel slag : An upscale trial of the NEUTRALSYRA project

    University essay from KTH/Materialvetenskap

    Author : Rahul Puthucode; [2019]
    Keywords : Landfilled High-alloyed Electric Arc Furnace EAF slag; Slag neutralization potential; Slag recycling;

    Abstract : The landfilling of slag obtained from the high alloyed Electric Arc Furnace (EAF) steel making process, constitutes an environmental treat for society as well as an economical problem for the companies producing it, due to the costs related to waste management practices. Conventional methods of slag recycling are abundantly used among the steelmaking business, but due to their particular physical properties, high- alloyed EAF slags cannot be properly valorized.

  5. 5. The Acute Metabolic Response of Intermittent Hypoxic Resistance Exercise : A Cross-Over RCT

    University essay from Gymnastik- och idrottshögskolan, GIH/Institutionen för idrotts- och hälsovetenskap

    Author : Jonas Falgin Hultgren; [2019]
    Keywords : Intermittent Resistaypoxic resistance exercise; lactate accumulation; cross-over RCT; RCT; Random Controlled Trial; healthy; men; blood; plasma; styrketräning; hypoxi; normoxi; saturation; laktat; ansamling; ph; blod; plasma; tung styrketräning; metabolisk; respons; randomiserad; kontrollerad; experiment; friska; unga; män; skelettmuskulatur;

    Abstract : Aim The aim for this present study was to investigate the acute metabolic response from intermittent resistance exercise during hypoxia, with the following research questions: (1) Are blood levels of lactate and glucose different between hypoxia and normoxia? (2) Does hypoxia induce higher lactate accumulation and pH reduction in the human skeletal muscle? (3) Is there a relationship between plasma-, blood- and muscle lactate? Method Eight healthy males (30 ± 2 years) performed 6 sets of unilateral leg extension on each leg (75% of 1RM) with randomized normoxic (20,9% inspired 𝑂2) and normobaric hypoxic (12% inspired 𝑂2) conditions. A total of 5 muscle biopsies was extracted from m. READ MORE
