  2. 1. Energy Efficient Air Quality Solutions for Vehicle Cabins

    Author : Dixin Wei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; climate system; private car; measurements; particulate matters; CO2; simulations; air quality; air filter; UFP; filter status; energy use; vehicle cabin;

    Abstract : Maintaining a good air quality level is essential for reducing potential health risks for human beings. Vehicle cabin is one common environment where people spend increasing amount of time in modern societies. It’s an environment challenged by elevated pollutants from surrounding traffics, especially small particles like PM2. READ MORE

  4. 2. Contaminant transport by air infiltration from crawl space to occupant area: Numerical simulations and field measurements in Swedish schools

    Author : Fredrik Domhagen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; crawl space; contaminants; infiltration model; monte carlo method; airtightness; air permeability;

    Abstract : Some Swedish school buildings built in the 1960’s and 1970’s have indoor air quality problems. Many of these buildings have a crawl space from which contaminants are suspected to originate. The poor indoor air quality cause discomfort among pupils and teachers and a solution to the problem is not always found. READ MORE

    Abstract : BackgroundAir quality in Africa has remained a relatively under-researched field. Most of the African population is dependent on biomass for cooking and heating, with most of the combustion happening in low efficiency stoves in unvented kitchens. READ MORE

  7. 5. Transforming Kiruna : Producing Space, Society, and Legacies of Inequality in the Swedish Ore Fields

    Author : Elisa Maria López; Vladislava Vladimirova; Sverker Finnström; Reetta Toivanen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Space; nature; inequality; Sweden; Kiruna; mining; Sámi; reindeer herding; urban planning; displacement; Kulturantropologi; Cultural Anthropology;

    Abstract : Extractive resources industries are irreversibly transforming land, air, water, life and society around the world at an unprecedented rate, and Sweden is no exception. This anthropological study analyzes acute issues related to this transformation:  the resettlement of six thousand residents of the city of Kiruna due to ground deformations caused by large-scale iron mining by the Swedish state-owned company LKAB (Luossavaara-Kiirunavaara AB).
