1. 36. Time-varying Waveform Distortion in Low voltage network

   Författare :Vineetha Ravindran; Sarah Rönnberg; Math Bollen; Marjan Popov; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interharmonics; Harmonic interactions; Voltage variations; Deep learning; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : The progressive advancement in new technologies has introduced new types of equipment into the grid. Some of these devices, which have gained significant popularity in the last few decades are photovoltaic (PV) systems and wind power systems from the generation side, and energy-efficient lighting i.e. LÄS MER

3. 37. Engineering of Native Cellulose Structure for Pharmaceutical Applications : Influence of Cellulose Crystallinity Index, Surface Area and Pore Volume on Sorption Phenomena

   Författare :Albert Mihranyan; Ragnar Ek; Maria Strømme; Hans Leuenberger; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; microcrystalline cellulose; Cladophora sp. algae; crystallinity index; surface area and pore volume; fractals; stability; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

   Sammanfattning : Cellulose powders from various sources were manufactured and characterized to investigate the influence of their crystallinity index, surface area, and pore volume on sorption phenomena and the relevant pharmaceutical functionality. The influence of the cellulose crystallinity index on moisture sorption was important at low and intermediate relative humidities. LÄS MER

4. 38. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

   Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

   Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

5. 39. Crystallographic Aspects of Protein Phasing at Very Low Resolution

   Författare :Klas Andersson; Jens Nyborg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

   Sammanfattning : A protein crystallographic method for obtaining structure factor phases of low-order reflections is presented. It is based on four observations: 1) The electron density inside proteins is relatively smooth and uniform at low resolution. LÄS MER

7. 40. Studies of Vacuum Dewatering on Low Grammage Paper Webs

   Författare :Rickard Granevald; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

   Sammanfattning : A laboratory scale apparatus to simulate high-vacuum dewatering of low grammage paper sheets, typically for tissue products has been constructed. Vacuum level, vacuum pulse dwell time and frequency of single vacuum pulses are in the range typical for a Through Air Drying (TAD) tissue machine. The vacuum pulse dwell time was varied from 0.
