  2. 1. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Author : Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

    Abstract : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. READ MORE

  4. 2. Speciation and Metabolic rate : Insights from an avian hybrid zone

    Author : S. Eryn McFarlane; Anna Qvarnström; Jenny Boughman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resting metabolic rate; life history; hybridization; speciation; reproductive isolation; Ficedula flycatcher; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

    Abstract : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. READ MORE

  5. 3. Effect of valve replacement for aortic stenosis on ventricular function

    Author : Ying Zhao; Michael Henein; Per Lindqvist; Eugenio Picano; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; aortic valve replacement; echocardiography; speckle tracking; exercise echocardiography; ventricular function; septal radial motion; twist; displacement; strain; strain rate;

    Abstract : Background：Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. READ MORE

  6. 4. Theory of economic development : nonlinearity, instability and non-equilibrium

    Author : Wei-Bin Zhang; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; economic growth and development; instability; structural change; bifurcation; non-equilibrium; centralization and decentralization; business cycle; the standard neoclassical growth model; growth rate; interest rate; inflation rate; choice of techniques; endogenous technological change;

    Abstract : The objective of this study is to propose an economic development theory within the framework of input-output systems and neoclassical economics. This study consists of nine chapters which are arranged in the following manner:In Chapter I, we discuss development problems, define some essential concepts, and provide a general historical sketch of economic growth theory.

  7. 5. Large deviation techniques applied to three questions of when

    Author : Ola Hammarlid; Anders Martin-Löf; Ingmar Kaj; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Large deviations; first passage time; stopping time; rate function; convex barrier; fallacy of large numbers; utility function; insurance; ruin; variable premium; generalized Ornstein-Uhlenbeck process; Mathematical statistics; Matematisk statistik;

    Abstract : Large deviation techniques are used to solve three problems; when is a distant convex barrier passed, when to accept a sequence of gambles and when is the time of ruin. This work is the collection of four papers. READ MORE
