  1. 1. On the chemical state and mobility of lead and other trace elements at the biogeosphere/technosphere interface

    Författare :Mattias Bäckström; Gunnar Jacks; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lead; trace elements; traffic; shooting range; peat; sediments; speciation; biokemi; Chemistry; Kemi; Kemi; Chemistry;

    Sammanfattning : Most inorganic contamination has occurred at the interface between the technosphere and the biogeosphere, even though atmospheric emissions have affected the entire globe. Several human activities now pose a substantial threat towards human health and the ecosystems. LÄS MER

  3. 2. High-resolution meteor exploration with tristatic radar methods

    Författare :Johan Kero; Asta Pellinen-Wannberg; Sigrid Close; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; meteors; meteoroids; interplanetary dust; radar; head echoes; ablation; meteoroid fragmentation; radar; huvudekon; ablation; meteorisk fragmentation; meteorer; meteoroider; interplanetärt stoft; Space engineering; Rymdteknik;

    Sammanfattning : A meteor observed with the naked eye is colloquially called a shooting star. The streak of light is generated by an extra-terrestrial particle, a meteoroid, entering the Earth’s atmosphere. The term meteor includes both luminosity detectable by optical means and ionization detectable by radar. LÄS MER

  4. 3. Gameplay (3D Game Engine + Ray Tracing = Visual Attention through Eye Tracking)

    Författare :Charlotte Sennersten; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Spelutveckling; Game development; Cognition; Vision; Gameplay; Instrumentation; 3D Game Engine; Eyegaze tracking;

    Sammanfattning : Research into gameplay can contribute to more self-conscious approaches to design, allowing designers to create effective gameplay with less testing, or to target specific cognitive and emotional affects of gameplay for serious games applications. Self-conscious design includes theoretically motivated design of game systems to facilitate gameplay motivated by cognitive, scientific and/or rhetorical theories of game affect and functionality.

  5. 4. Systematic design of glulam trusses

    Författare :Helena Johnsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Sammanfattning : The design of a structure should be regarded as the design of a system. In this licentiate thesis a method (concurrent engineering) for the design of systems is studied parallel with the development of the system itself. LÄS MER

  7. 5. Determinants of hearing impairment in Swedish hunters : an e-epidemiological approach

    Författare :Louise Honeth; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: 290 236 persons bought a hunting license in Sweden 2014/15. Hunters are spread all over the country and come from all socioeconomic groups. Recreational fiearms can produce peak noise levels between 156-164 decibel sound pressure levels (dB SPL). LÄS MER
