   Abstract : In recent decades, Rwanda has been affected by the loss and fragmentation of natural habitats for native species of animals and plants. As a consequence, landscape connectivity—i.e. READ MORE

4. 2. Sound intolerance : characteristics, psychosocial work factors and reactions to exposure

   Author : Johan Paulin; Linus Andersson; Steven Nordin; David Baguley; Umeå universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sound intolerance; hyperacusis; psychosocial work environment; Noise sensitivity scale; white noise; Ljudintolerans; hyperakusi; psykosocial arbetsmiljö; vitt brus; ljudöverkänslighet; Psychology; psykologi;

   Abstract : Sound intolerance refers to an adverse reaction to sounds at sound pressure levels most people do not find bothersome. It is sometimes associated with hearing loss and tinnitus, but neither conditions are a prerequisite for being intolerant to sounds. READ MORE

5. 3. Simplifying complex models : Application of modeling tools in exposure assessment of organic pollutants

   Author : Emma Undeman; Michael McLachlan; Kathrin Fenner; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; mass balance model; environmental modeling; exposure modeling; bioaccumulation; organic contaminants; emission estimate; plant model; steady state; poly parameter linear free energy relationship; PPLFER; ecosystem susceptibility; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

   Abstract : Thousands of chemicals are used in society, but the exposure to humans and other organisms has been measured only for a small number of compounds. Modeling tools constitute low-cost and effective alternatives to measurements for the assessment of exposure. READ MORE

6. 4. Absorption of Sound : On the effects of field interaction on absorber performance

   Author : Anna Färm; Mats Åbom; Ragnar Glav; Susann Boij; Gareth Bennett; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sound absorption; Porous absorbers; Bulk reaction; Local reaction; Boundary layer; Grazing flow; Temperature gradients; Surface impedance; Sound field; Pass-by noise; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : Environmental noise has for decades been a well known problem, especially in urban areas. As noise requirements for vehicles are sharpened, noise reducing concepts are needed in early design stages requiring accurate simulations to support the design. READ MORE

7. 5. Broadening Horizons : The FMECA-NETEP model, offshore wind farms and the permit application process

   Author : John Ohlson; Bo Carlsson; Håkan Thorstensson; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cumulative impact; risk; offshore wind farm OWF ; FMECA; kumulativa effekter; risk; havsbaserad vindkraft; Miljövetenskap; Environmental Science;

   Abstract : Abstract  The permit application process for offshore wind farms (OWF) in Sweden conceivably requires a comprehensive and transparent complement within risk management. The NETEP framework (covering risks concerning navigation, economics, technology, environment and politics), based on a futures planning mechanism (STEEP) has consequently been brought forward as a structure for the application of FMECA (Failure Mode, Effects, and Criticality Analysis) methodology to the permit application process of the Swedish offshore wind farm sector.
