  1. 1. Placental Function : An Epidemiological and Magnetic Resonance Study

    Author : Sara Sohlberg; Anna-Karin Wikstrom; Matts Olovsson; Ajlana Mulic-Lutvica; Johan Wikström; Karel Marsal; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; body height; body mass index; early preeclampsia; late preeclampsia; magnetic resonance imaging; placenta; perfusion; IVIM; risk factors; energy metabolism; magnetic resonance spectroscopy; 31P-MRS; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : Placental function is central for normal pregnancy and in many of the major pregnancy disorders. We used magnetic resonance imaging techniques to investigate placental function in normal pregnancy, in early and late preeclampsia and in intrauterine growth restriction. READ MORE

  2. 2. Perinatal Depressive Symptoms among Women in North-Eastern Thailand : Risk Factors, Support and Prevention

    Author : Nitikorn Phoosuwan; Pranee Lundberg; Leif Eriksson; Katarina Hjelm; Eva Nissen; Uppsala universitet; []
    Keywords : Perinatal depressive symptoms; Edinburgh Postnatal Depression Scale; risk factors; life situation; support; intervention programme; public health professionals; Caring Sciences; Vårdvetenskap;

    Abstract : Perinatal depressive symptoms among women remain a global burden. Improvements in self-efficacy among public health professionals (PHPs) in primary healthcare settings to detect and manage perinatal depressive symptoms among women are needed. READ MORE

  3. 3. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Author : Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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. 4. Fixed points, fractals, iterated function systems and generalized support vector machines

    Author : Xiaomin Qi; Sergei Silvestrov; Anatoliy Malyarenko; Daniel Andren; Viktor Abramov; Mälardalens högskola; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; support vector machine; fixed points; iterated function system; variational inequality; Mathematics Applied Mathematics; matematik tillämpad matematik;

    Abstract : In this thesis, fixed point theory is used to construct a fractal type sets and to solve data classification problem. Fixed point method, which is a beautiful mixture of analysis, topology, and geometry has been revealed as a very powerful and important tool in the study of nonlinear phenomena. READ MORE

  5. 5. Topics in polynomial sequences defined by linear recurrences

    Author : INNOCENT NDIKUBWAYO; Boris Shapiro; Rikard Bøgvad; Tamás Forgács; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; recurrence relation; q-discriminant; generating function; polynomial sequence; support; real zeros; matematik; Mathematics;

    Abstract : This licentiate consists of two papers treating polynomial sequences defined by linear recurrences.In paper I, we establish necessary and sufficient conditions for the reality of all the zeros in a polynomial sequence {P_i} generated by a three-term recurrence relation P_i(x)+ Q_1(x)P_{i-1}(x) +Q_2(x) P_{i-2}(x)=0 with the standard initial conditions P_{0}(x)=1, P_{-1}(x)=0, where Q_1(x) and Q_2(x) are arbitrary real polynomials.
