  1. 6. Storgodsdrift. Godsekonomi och arbetsorganisation i Skåne från dansk tid till mitten av 1800-talet

    Författare :Mats Olsson; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early Modern times; feudal; corvée labour; peasant; tenant farmer; Gutsherrschaft; demesne; grain production; Landed estate; manorial; 19th century; Scania; Social and economic history; Ekonomisk och social historia;

    Sammanfattning : The aim of this study is to systematically survey and analyse the Scanian manors’ economic and labour organisational development from the province’s Danish times to the middle of the nineteenth century. In this thesis the various surveys provides some clear results that make it possible to generalise the Scanian estate development. LÄS MER

  3. 7. Historical Urban Agriculture : Food Production and Access to Land in Swedish Towns before 1900

    Författare :Annika Björklund; Mats Widgren; Johannes Renes; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban agriculture; urban history; urban geography; Sweden; town; food production; food consumption; Uppsala; historical geography; land allocation; cadastral maps; urban land-use; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : This doctoral thesis analyses the role of historical urban agriculture in a long-time perspective, through a combination of overarching surveys of Swedish towns and detailed studies of one town – Uppsala in east-central Sweden. The study shows how agricultural land – town land – of various sizes was donated to towns repeatedly during medieval times and in the 16th and 17th centuries. LÄS MER

  4. 8. High dynamic stiffness nano-structured composites for vibration control : A Study of applications in joint interfaces and machining systems

    Författare :Qilin Fu; Cornel-Mihai Nicolescu; Per Nylén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vibration control; High dynamic stiffness; Metal matrix composite; Nano structures; Plasma enhanced chemical vapour deposition PECVD ; High power impulse magnetron sputtering HiPIMS ; Adiabatic; Machining; Regenerative tool chatter; Production Engineering; Industriell produktion;

    Sammanfattning : Vibration control requires high dynamic stiffness in mechanical structures for a reliable performance under extreme conditions. Dynamic stiffness composes the parameters of stiffness (K) and damping (η) that are usually in a trade-off relationship. This thesis study aims to break the trade-off relationship. LÄS MER
