  2. 1. On the role of NMDA receptor subunits in the acute and chronic effects of nicotine

    Author : Alexander Kosowski; Karolinska Institutet; Karolinska Institutet; []
    Keywords : PCR; microdialysis; Wistar;

    Abstract : Nicotine is considered the main dependence-producing constituent in tobacco products. In analogy with other drugs of abuse, nicotine enhances dopamine (DA) neurotransmission within the mesocorticolimbic DA system. READ MORE

  4. 2. Consequences of bushmeat hunting in tropical forests

    Author : Edu Efiom; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Tropical rainforests; bushmeat hunting; primates; seedling recruitment; interseedling competition; community composition; functional traits; ecosystem services; human livelihoods;

    Abstract : This thesis evaluates the effect of bushmeat hunting in southeastern Nigerian rainforests on: 1) adult tree, seedling, and animal community compositions 2) germination and survival among seedlings in association with competition 3) changes in community composition at multiple trophic levels 4) leaf nitrogen concentration (LNC), leaf mass per area (LMA) and stem specific density (SSD) 5) on human reliance on forest resources and rural people use forest resources. Data for the first four evaluations were obtained from surveys, manipulative experiments in seedling plots and collected leaf samples in three pairs of sites with high (hunted sites) and low (protected sites) hunting pressure but with similar adult tree composition.

  5. 3. Postoperative sore throat and hoarseness : clinical studies in patients undergoing general anasthesia

    Author : Maria Jaensson; Ulrica Nilsson; Anil Gupta; Jonas Åkeson; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hoarseness; postoperative; complication; endotracheal; tube; laryngeal mask airway; gender; risk factor.; Vårdvetenskap; Nursing Science;

    Abstract : A common problem following general anesthesia is postoperative sore throat (POST) and postoperative hoarseness (PH). Symptoms directly correlated with less satisfaction according to the patients. READ MORE

  6. 4. Models and Methods for Random Fields in Spatial Statistics with Computational Efficiency from Markov Properties

    Author : David Bolin; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; random fields; Gaussian Markov random fields; Matérn covariances; stochastic partial differential equations; Computational efficiency;

    Abstract : The focus of this work is on the development of new random field models and methods suitable for the analysis of large environmental data sets. A large part is devoted to a number of extensions to the newly proposed Stochastic Partial Differential Equation (SPDE) approach for representing Gaussian fields using Gaussian Markov Random Fields (GMRFs).

  7. 5. Morphological and chemical leaf traits of tropical montane tree species and their responses to warming

    Author : Manishimwe Aloysie; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; tropical montane forests; tropical trees; leaf morphology; leaf nutrients; warming climate; climate change;

    Abstract : Leaf morphological and chemical traits of tropical trees vary along climate gradients, but it is currently unclear how they will respond to a rapidly warming climate and how this will vary among species. Considering this, tropical trees native to East and Central Africa were investigated in three complementary studies in Rwanda. READ MORE
