  1. 1. Ecological aspects of antimicrobial susceptibility of anaerobic bacteria in Nicaragua

    Author : Mercedes Cáceres; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Antimicrobial susceptibility; normal flora; anaerobic infections; B-lactamase; enterotoxigenic B. fragilis;

    Abstract : Anaerobic bacteria are the predominant constituents of the normal flora on the skin and the mucous membranes of the human body. They may also act as potent pathogens in a variety of endogenous infections. Antimicrobial resistance is an increasing problem with anaerobic and aerobic bacteria. Different mechanisms for such resistance are known. READ MORE

  2. 2. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

    Author : Mercedes Andrea Olivas Ogaz; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

    Abstract : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. READ MORE

  3. 3. Theoretical Studies on Electronic Structure, Spectra and Conductivity of Pristine and Alkali Doped Polyacetylene

    Author : Lucía Mercedes Rodrigues Monge; Chalmers University of Technology; []
    Keywords : theoretical calculations; electron transfer; conductivity; polyacetylene; alkali metal; ab-initio methods; charge transport; semiempirical methods; doping;

    Abstract : The present thesis is a theoretical investigation of the electronic properties of linear polyenes to get an insight into conductive phenomena in pristine and doped polyacetylene. Conductivity in polyacetylene is a complex phenomena and cannot be treated within simple band models. READ MORE

  4. 4. A Brave New Workplace: Disclosing the smart and the dark sides of the alternative office spaces

    Author : Claudia Manca; Matti Kaulio; Mercedes Grijalvo; Miguel Palacios; Viviane Sergi; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; alternative workplace; workplace flexibility; new ways of working; activity-based work; collaborative space; tensions; paradoxes; space production; social space; alternativ arbetsplats; flexibilitet på arbetsplatsen; nya arbetssätt; aktivitetsbaserat arbete; samarbetsutrymme; spänningar; paradoxer; skapande av rum; socialt utrymme; Industrial Economics and Management; Industriell ekonomi och organisation;

    Abstract : In recent decades, several knowledge work organizations have introduced alternative workplaces (AWs) that are implemented through flexible and collaborative office models. Their rapid diffusion has been prompted by the deterministic assumption that these may influence workers’ relations and behaviors in the office, in a way that is conducive to greater collaboration and adaptive flexibility.

  5. 5. Learning English in a Multi-User Virtual Environment : Exploring Factors Affecting Participation

    Author : Airong Wang; Mats Deutschmann; Mercedes Rico Garcia; Mittuniversitetet; []
    Keywords : HUMANITIES; HUMANIORA; Activity theory; Conversational Analysis; Discourse analysis; Ecology of language learning; Model of factors affecting participation; Multi-User Virtual Environment; Participation; Second Life; The sociocultural perspective on learning; Technology adoption;

    Abstract : Online language learning and teaching is a field that has received a significant amount of research attention. What factors could affect student participation in simpler online learning environments has been investigated by researchers, but there has been limited study of factors affecting participation in complex Multi-User Virtual Environments.
