  2. 11. Structure Function Relationships in Pyrimidine Degrading and Biocatalytic Enzymes, and Their Implications for Cancer Therapy and Green Chemistry

    Author : Dirk Maurer; Doreen Dobritzsch; Mikael Widersten; Rikkert Wierenga; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; β-Ureidopropionase; Dihydropyrimidine Dehydrogenase; Alcohol Dehydrogenase; Pyrimidine catabolism; 5-Fluorouracil; CASTing; X-ray Crystallography;

    Abstract : This thesis includes the work of two separate projects, studies on pyrimidine degrading enzymes and studies on in vitro evolved enzymes. The common denominator of both projects was the use of structural information to explain functional effects, observed in the studied biocatalysts. READ MORE

  4. 12. The heart in hereditary transthyretin amyloidosis : clinical studies on the impact of amyloid fibril composition

    Author : Björn Pilebro; Ole Suhr; Henning Mölgaard; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Amyloidosis; Transthyretin; Cardiomyopathy; Echocardiography; Scintigraphy; Positron emission tomography; cardiovascular disease; hjärt- och kärlforskning; kardiologi; Cardiology; Clinical Physiology; klinisk fysiologi;

    Abstract : Background Hereditary transthyretin amyloid (ATTRm) amyloidosis is a systemic disease mainly affecting the peripheral nervous system and the heart. The disease is inherited in an autosomal dominant manner with a varying penetrance. It is caused by mutations in the transthyretin (TTR) gene. Today more than 100 disease causing mutations are known.

  5. 13. Digital Predistortion for the Linearization of Power Amplifiers

    Author : Jessica Chani Cahuana; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; behavioral model; Volterra series; nonlinear; digital predistortion; Doherty power amplifier; power amplifier; efficiency;

    Abstract : High efficiency and linearity are indispensable requirements of power amplifiers. Unfortunately they are difficult to obtain simultaneously, since high efficiency PAs are nonlinear and linear PAs may have low efficiency. READ MORE

  6. 14. High Efficiency Microwave Amplifiers and SiC Varactors Optimized for Dynamic Load Modulation

    Author : Christer Andersson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear measurements; power amplifiers; load modulation; GaN; SiC; varactors; HEMT; wide bandgap technology; energy efficiency;

    Abstract : The increasing use of mobile networks as the main source of internet connectivity is creating challenges in the infrastructure. Customer demand is a moving target and continuous hardware developments are necessary to supply higher data rates in an environmentally sustainable and cost effective way. READ MORE

  7. 15. Simulations of Transport Phenomena and Porous Structures Using Dissipative Particle Dynamics

    Author : Erik Johansson; Värmeöverföring; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The topic of this work is simulations of porous materials and transport phenomena at a mesoscopic length scale, i.e., a length scale larger than an individual atom but smaller than the continuum. The porous material studied is a membrane used in fuel cells. READ MORE
