  1. 1. Adhesion to machined and laser ablated wood surfaces

    University dissertation from Institutionen för produktionssystem

    Author : Micael Stehr; KTH.; [1999]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; ablation; adhesion; checks; coating; cracks; excimer laser; gluing; IR laser; mechanical machining; mechanical weak boundary layer; microscopy; notched specimens; pine; planing; sample preparation; sawing; scanning electronmicroscopy; spruce; tip-cracks; UV laser; weak boundary layer; wood;

    Abstract : This thesis is a contribution to the R&D-program ValueActivation at KTH,Division of Wood Technology and Processingand containsfive papers related to the evaluation and development ofmachining techniques (mechanical and irradiation treatments)whereby weak boundaries at the wood surfaces in the form of(mechanical) weak boundary layers and (micro) cracks due tomechanical treatment can be avoided.The first paper describes the development of a method–using a UV laser–to study the mechanically weakenedboundaries.

  2. 2. Malthusian Progress

    University dissertation from Institutionen för produktionssystem

    Author : Jacob Weisdorf; Lund University.; Lunds universitet.; [2011]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social Mobility; Preventive Checks; Positive Checks; Industrial Revolution; French Revolution; Mortality; Longevity; Malthusian Model; Fertility; Industrious Revolution ; Economic Growth;

    Abstract : Some scholars maintain that pre-industrial England was held in a Malthusian ‘trap’, and that this trap prevented the sustained growth of real wages until as late as 1800. Opponents to this view argue that the structural transformations occurring in preindustrial England – urbanization, labour reallocation between sectors, and human capital investments – are features of development that are incompatible with the idea of Malthusian stagnation.

  3. 3. Criminal Records in Sweden. Regulation of access to criminal records and the use of criminal background checks by employers

    University dissertation from Göteborg : University of Gothenburg

    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Criminal records; criminal background checks; surveillance; function creep;

    Abstract : This thesis examines the regulation of access to criminal records in Sweden and the actual and potential use of criminal background checks by employers in hiring processes. In recent years, more and more Swedish employers have been required by law to check their job applicants’ criminal records. READ MORE

  4. 4. A study of contaminated lubricants concerning wear, rheological properties and sample withdrawal

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Sven Berg; Luleå tekniska universitet.; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : The wear of a machine, whether it is due to fatigue or abrasive wear, will add contaminants, in the form of particulates, to the system in question. Since a total breakdown of the machine can be rather costly, one wants to be able to foresee breakdowns and increase the machine life. READ MORE

  5. 5. Laminated Veneer Products Shape Stability and Effect of Enhanced Formability on Bond-Line Strength

    University dissertation from Växjö : Linnaeus University Press

    Author : Lars Blomqvist; Linnéuniversitetet.; [2016]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Abstract : This thesis concerns two aspects of the manufacture of laminated veneer products (LVPs). The first aspect is related to the possible improvement of the shape stability of LVPs, and the second has its starting point in the modification of the veneer for enhanced formability as well as the question of whether and how these modifications affect the bond-line strength.
