  1. 1. On Toxicant-Induced Succession in Periphyton Communities: Effects of Single Chemicals and Chemical Mixtures

    University dissertation from Göteborg : University of Gothenburg

    Author : Tobias Porsbring; Göteborgs universitet.; Gothenburg University.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; community ecotoxicology; toxicant-induced succession; chemical mixtures; concentration addition; independent action; diatoms; periphyton; algal pigments; algal sterols;

    Abstract : This thesis deals with the effects of single chemicals and chemical mixtures on biological communities. Ecosystems are exposed to complex mixtures of chemicals, and because combination effects can occ... READ MORE

  2. 2. Significance of transport dynamics on concentration statistics and expected mass fraction based risk assessment in the subsurface

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Veljko Srzic; Vladimir Cvetkovic; Olaf A. Cirpka; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Local scale dispersion; Heterogeneity structure; Concentration moments; Moment collapse; Expected mass fraction;

    Abstract : This thesis relies on a Langrangian framework used for conservative tracer transport simulations through 2-D heterogeneous porous media. Conducted numerical simulations enable large sets of concentration values in both spatial and temporal domains. READ MORE

  3. 3. Lung aeration and pulmonary gas exchange during general and epidural anaesthesia : Influenced by inspired oxygen concentration and diaphragm shape

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Adrian Reber; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; Anesthesia: epidural; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Clinical Physiology; klinisk fysiologi;

    Abstract : Induction of general anaesthesia causes a rapid decrease in functional residual capacity, which can promote alveolar collapse (atelectasis) and airway closure in dependent lung regions. Mismatching of ventilation and perfusion (VA/Q) in the lungs is accompanied by impairment of pulmonary gas exchange. READ MORE

  4. 4. Market structure and economic status for firms producing single-family houses in Sweden

    University dissertation from Växjö : Linnaeus University

    Author : Fredrik Lindblad; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wooden Houses; Wooden single-family houses; Wooden multi- family houses; Financial Performance; Risk Position; Economic distress; Z- score model; Industry Structure; Productivity; Off-site construction; Industry concentration; Maskinteknik; Mechanical Engineering;

    Abstract : The gradually changing behavior of the population, towards urbanization, ledto an increased shortage of available housing. This development has resultedin a serious issue in Sweden, where too few firms are providing solutions formulti-family houses in wood. READ MORE

  5. 5. Amorphous magnesium carbonate nanomaterials Synthesis, characterization and applications

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jiaojiao Yang; Ken Welch; Mika Lindén; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high surface-to-volume ratio; nanoparticles; mesoporous; magnesium carbonate; amorphous drugs; supersaturated concentration; general adhesives; UV-shielding;

    Abstract : High surface-to-volume ratio materials, including nanoparticles and mesoporous materials, have a number of applications due to their large surface area and special structures. Traditional approaches for synthesizing high surface-to-volume ratio nanomaterials are often complicated, expensive or environmentally unfriendly. READ MORE
