  1. 1. Critical loads - assessment of uncertainty

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Andreas Barkman; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; landscape planning; regionalisation; forestry; BC Al; sensitivity analysis; risk assessment; Monte Carlo simulation; PROFILE; critical level; exceedance; Acidification; forest soil; policy; EMEP; GIS.; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Abstract : The effects of data uncertainty in applications of the critical loads concept were investigated on different spatial resolutions in Sweden and northern Czech Republic. Critical loads of acidity (CL) were calculated for Sweden using the biogeochemical model PROFILE. READ MORE

  2. 2. Determination of the Critical Moisture Level for Mould Growth on Building Materials

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Pernilla Johansson; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Crawl space; Fungus; Mould resistance; Wood; Building materials; Mould; Critical moisture level; Attic; Relative humidity; Cyclic conditions; Laboratory method;

    Abstract : The susceptibility to mould growth varies between building materials. The factors that most affect mould growth, the relative humidity (RH) and temperature also vary in different parts of buildings. One way of preventing the growth of mould in buildings is therefore to choose building materials that can withstand the expected conditions. READ MORE

  3. 3. Organizational Lessons Learned Natural Hazards Affecting Critical Infrastructure

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Monika Rydstedt Nyman; Lars Nyberg; Magnus Johansson; Eva Liljegren; Henrik Tehler; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; natural hazards; critical infrastructure; feedback; lessons learned; collective learning; memory building; Risk and Environmental Studies; Risk- och Miljöstudier;

    Abstract : This thesis focuses on an issue often presented as a solution – albeit a debated one ­– namely learning, specifically lessons learned from natural hazard events. Empirically, this thesis examines flooding and avalanches in a Swedish context, centering on systematic feedback mechanisms and learning from extreme events. READ MORE

  4. 4. Towards Systemic Governance of Critical Infrastructure Protection State and Relevance of a Swedish Case

    University dissertation from Sundsvall : Mid Sweden University

    Author : Christine Große; Aron Larsson; Olof Björkqvist; Pär M. Olausson; Alexander Fekete; [2020]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systemic Thinking; Infrastructure; Governance; Critical Infrastructure Protection; Complex Systems; Soft Operations Research; design-oriented Information Systems Research; Integrative System Analysis; KISA; STYREL; Multi-level Planning; Adaption; Emergence; Entropy; Systemic Governance;

    Abstract : The protection of infrastructure that is critical to society’s functionality, survival and progression has gained significance for both national security and research because of its large-scale and interdependent nature. Critical infrastructure can be viewed as a complex, socio-technical system-of-systems that imposes extensive requirements on governance efforts to foster critical infrastructure protection (CIP), regardless of whether it involves public organisations, private organisations or both.

  5. 5. Critical Moisture Conditions for Mould Growth on Building Materials

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Pernilla Johansson; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould; critical moisture level; building material; relative humidity; mould resistance; crawl space; attic;

    Abstract : Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. READ MORE
