  1. 1. Tourists' vacation choice structure : Influence of values and implications for green tourism

    Författare :Therese Hedlund; Maria Bengtsson; Anna-Carin Nordvall; Øystein Aas; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; vacation choice structure; values; green attitudes; green tourism; företagsekonomi; Business Studies;

    Sammanfattning : In the vacation choice structure, denoting how vacation choices such as choice of destination, travel mode, and accommodation, are related and prioritized by tourists, every choice plays an important and unique role. Although it has been recognized that vacation choices inter-relate in several different aspects, previous research has primarily studied the primacy aspect. LÄS MER

  2. 2. Peasant proudction and limits to labour Thyolo and Mzimba Districts in Malawi, mid-1930s to late-1970s

    Författare :Erik Green; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; production; peasant; Malawi; Africa; accumulation; agriculture; Ekonomisk och social historia;

    Sammanfattning : The persistence of a low productive peasant sector in sub-Saharan Africa is one of the enigmas of development research. This study approaches the question from a historical perspective by analysing the paths of agrarian change in two contrasting cases in Malawi from the mid-1930s to the late 1970s. LÄS MER

  3. 3. Controlling Forced Response of a High Pressure Turbine Blade

    Författare :Jeff Green; Torsten Fransson; Robert Kielb; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Vibration induced High Cycle Fatigue (HCF) is a major consideration in designing gas turbines. Indeed, the Gas Turbine manufacturer must demonstrate that the vibration level of the turbomachinery blading is acceptably low, usually by using an engine strain gauge test. LÄS MER

  4. 4. Genetic structure, demographic change and extinction dynamics in the collared lemming and woolly mammoth

    Författare :Eleftheria Palkopoulou; Love Dalén; Richard Edward Green; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : In light of current climate change it is critical to understand how different species have been affected in the past by well-known climatic events. In this thesis, DNA was retrieved from ancient material to study the population dynamics of two cold-adapted taxa that capture the extremes of body size range in mammals: the collared lemming (Dicrostonyx sp.

  5. 5. Biomass-derived nanoscopic catalysts for water treatment : Structure-property relationship investigation

    Författare :Jianhong Chen; Adam Slabon; Germán Salazar Alvarez; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; green chemistry; water purification; electrochemistry; photochemistry; biomass material; structure-property relationship; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : Green Chemistry has received widespread interest due to its capacity to meet environmental and economic objectives. The Twelve Principles were proposed to better perform Green Chemistry and have become the guideline for solving many environmental issues. Water contamination has become a major global challenge in the 21st century. LÄS MER
