  1. 1. Dermal exposure to pesticides in Nicaragua : a qualitative and quantitative approach

    Författare :Aurora Aragón; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dermal exposure; developing country; pesticides; subsistence farmers; fluorescent tracer; visual scoring system; skin wipes; pesticide residues.;

    Sammanfattning : Background: Pesticide use continues to be a serious public health problem in developing countries, despite decades of safe pesticide use strategies. In Nicaragua, organophosphate insecticides, in particular chlorpyrifos and methamidophos are responsible for about half of the acute pesticide poisonings. LÄS MER

    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; vacation history; vacation memories; holiday consumption; history of travel and tourism; history of the holiday; views on nature; views on social relations; views on family; views on relaxation and rest; motives for legislation; advertising vacation; semesterhistoria; semesterminnen; semesterfrågelista; semesterkonsumtion; turismhistoria; resehistoria; semesterresa; naturuppfattning; syn på sociala relationer; syn på familjen; syn på vila; motiv till semesterlagstiftning; semesterreklam; ekonomisk historia; Economic History;

    Sammanfattning : The dissertation provides an in-depth analysis of Swedes’ perceptions about vacations during the period of 1938 to 1959. The aim is to contribute to a more thorough understanding of vacation-related consumption, which in Sweden was of growing economic importance from the 1930s and onwards. LÄS MER

  3. 3. Det var en lyckad semester! : Semesterfirande svenskars preferenser år 1938-1959

    Författare :Aurora Lewén; Mats Morell; Fredrik Sandgren; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; vacation; holiday; preferences; ekonomic history of Sweden; 1900s; consumption; consumer attitudes; tourism history; semester; preferenser; ekonomisk historia; Sverige; 1900-talet; konsumtion; konsumenter – attityder; turismhistoria; ekonomisk historia; Economic History;

    Sammanfattning : This licentiate thesis analyzes preferences among Swedish vacationers during the period of 1938-1959. The aim of the thesis is to closely examine these preferences in order to contribute to a more fully developed understanding of holiday-related consumption during the period. LÄS MER

  4. 4. Multi Quanta Relaxation and Nonclassicality of Nonlinear Oscillators

    Författare :Aurora Voje; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nonlinear Damping; Nonclassical States; Entanglement; Quantum Duffing Oscillator;

    Sammanfattning : The focus of the study is the free quantum evolution of Duffing oscillators which are nonlinearly coupled to bosonic environments. The work evolves from a particular system of an undamped, nonlinear graphene resonator mode to a more generalized framework of oscillator modes interacting with two different configurations of bosonic environments.

  5. 5. Dynamic Characteristics of Floating Breakwaters

    Författare :Aurora Xiaomeng Lei; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; floating breakwaters; couplings joints ; dynamic cables; dynamic response; line tension; wave attenuation; wave reflection;

    Sammanfattning : The dynamic behaviour of interconnected floating breakwaters has been studied theoretically and experimentally. For this type of shore-protection system, problems that must be dealt with include wave loads on the breakwaters caused by the interaction between the bodies and the waves, motions of the moored breakwaters caused by the waves, changed wave fields in front of and behind the breakwaters, and forces on the mooring cables and in interconnections between breakwater units.
