   Sammanfattning : The demands for an ever higher data rate and a more varied functionality at minimal cost and power consumption have been the driving force behind most innovations in wireless communication systems. Intensive efforts have been made to develop Radio Frequency (RF) Integrated Circuits (ICs) and systems using low-cost Complementary Metal Oxide Semiconductor (CMOS) processes. LÄS MER

3. 2. Early diagnosis, treatment, and Health-Related Quality of Life in women with mild Breast Cancer-Related Lymphedema

   Författare :Katarina Blom; Rehabilitering och hållbar hälsa; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lymphedema; breast cancer; compression garment; Diagnosis; treatment; health-related quality of life;

   Sammanfattning : Background: Early diagnosis and treatment of Breast Cancer-RelatedLymphedema (BCRL) are important to prevent lymphedema progress and impacton Health-Related Quality of Life (HRQOL). The treatment includes self-care andtreatment with compression garment. In mild BCRL, the lymphedema can be local, without an increase in arm volume. LÄS MER

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Electronic devices with wireless connectivity are fast becoming a part of daily life. According to some estimates, in the next five years, 10 billion new devices with internet connectivity would be produced. LÄS MER

5. 4. Crankshaft speed measurements and analysis for control and diagnostics of diesel engines

   Författare :Roger Johnsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk akustik; Engineering Acoustics;

   Sammanfattning : The increasing demands from governments on the engine manufactures to lower the fuel consumption, lower the exhaust emissions and to reduce the noise have lead to an intensive research in the combustion process. Measurement of the combustion process inside the cylinder is only suitable in laboratory environment due to a number of limitations; the pressure transducer needed to measure the pressure is expensive, difficult to mount in the cylinder and has a limited lifetime that is much shorter than the engine's lifetime.

7. 5. Elicitor-induced formation of secondary products in plant cell cultures. Production of benzophenanthridine alkaloids in Eschscholtzia californica Cham. and hydroxycinnamic acid tyramides in Nicotiana glutinosa L

   Författare :Mirza Villegas; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; macarpine; chelerythrine; sanguinarine; benzophenanthridine alkaloids; Nicotiana glutinosa; Eschscholtzia californica; secondary metabolites; Key words elicitors; immobilisation; hydroxycinnamoyltyramides.; Plant biochemistry; Växtbiokemi;

   Sammanfattning : Biotic and abiotic elicitors induce biosynthesis of secondary metabolites (phytoalexins) as a defense against pathogenic organisms in plants. The use of cell suspension cultures in combination with elicitors offer excellent experimental model systems for studies on various elicitor-induced responses of plant tissues. LÄS MER
