  1. 1. A Study of Environmental Impacts, Environmental Awareness and Pro-Ecological Initiatives in the Hotel Industry

    Författare :Paulina Bohdanowicz; KTH; []
    Nyckelord :hotels; environmental impacts; mitigation measures; survey; hoteliers; hotel customers; environmental attitudes; environmental awareness; pro-ecological activities; incentives;

    Sammanfattning : Throughout the millennia commercial lodging establishmentshave evolved to what is today known as the hospitalityindustry. Hotels constitute one of the main, and stillexpanding, pillars of this sector and are highly unique amongother commercial buildings. They are designed to providecomfort and services twenty-four/seven. LÄS MER

  3. 2. Rates and patterns of molecular evolution in avian genomes

    Författare :Paulina Bolívar; Hans Ellegren; Carina F. Mugal; Mikkel Heide Schierup; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; recombination; GC-biased gene conversion; Hill-Robertson interference; effective population size; dN dS; distribution of fitness effects; avian genomes; collared flycatcher; sex chromosomes; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Sammanfattning : Evolution is the change in inherited characteristics of a population through subsequent generations. The interplay of several evolutionary mechanisms determines the rate at which this change occurs. LÄS MER

  4. 3. Effects of Protons and Small Alcohols on the Oxygen-Evolving Complex of Photosystem II

    Författare :Paulina Geijer; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; EPR; pH; methanol; S3; S2; S0; YZ; Mn cluster; Oxygen-evolving complex; S-states; Biochemistry; Metabolism; Biokemi; metabolism;

    Sammanfattning : Higher plants and algae use oxygenic photosynthesis to convert solar energy to reducing equivalents and chemical energy. The ultimate electron donor to oxygenic photosynthesis is water. Oxidation of water to oxygen occurs in the oxygen-evolving complex (OEC) in Photosystem II (PSII). The OEC is composed of four Mn atoms, Ca2+ and Cl-. LÄS MER

  5. 4. MOLECULAR ASPECTS OF ENDOTHELIAL CELL FUNCTION AND HYPOXIA-DEPENDENT TUMOR ANGIOGENESIS

    Författare :Paulina Kucharzewska; Bröstcancer-genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hypoxia; hypoxia-inducible factor; angiogenesis; anti-angiogenic therapy; endothelial cell; polyamines; microRNA; extracellular membrane vesicles; exosomes; glioblastoma;

    Sammanfattning : Hypoxia, or deficient oxygen levels, is an inherent feature of rapidly expanding tumor tissue. In order to survive in the hostile, hypoxic environment and to restore the supply of oxygen and nutrients tumor cells activate a variety of adaptive mechanisms. Among them, hypoxia-induced angiogenesis, i.e. LÄS MER

  7. 5. Understanding as experiencing a pattern

    Författare :Paulina Lindström; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; Understanding; eye-tracking; mathematical problem solving; cognition; pedagogy;

    Sammanfattning : The thesis proposes that understanding is a matter of experiencing a pattern. To experience a pattern involves seeing how a task, principle, or problem space is structured; to attend to the relevant information; and to be able to use that information as it relates to the knowledge domain at hand.
