  1. 16. Pharmaceutical binders and their function in directly compressed tablets : Mechanistic studies on the effect of dry binders on mechanical strength, pore structure and disintegration of tablets

    Författare :Sofia Mattsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacy; Compaction; tablet; binder; pore structure; disintegration; FARMACI; PHARMACY; FARMACI; farmaceutisk farmakologi; Pharmaceutical Pharmacology;

    Sammanfattning : In this thesis, the strength-enhancing mechanisms of dry binders in direct compression were studied. The systems investigated were binary mixtures containing various compounds and binders. Among the binders used were a series of different molecular weights of polyethylene glycol. LÄS MER

  2. 17. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    Författare :Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

    Sammanfattning : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. LÄS MER

  3. 18. Characterisation of Optical Fibers Using Dual-Comb Swept-Wavelength Interferometry

    Författare :Ekaterina Deriushkina; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coupled-core multi-core fibers; channel modeling; swept-wavelength interferometry; characterisation measurements; transfer function; dual-comb spectroscopy;

    Sammanfattning : The growth in data traffic coupled with trends in internet use will result in a requirement for interfaces of the network to reach Tb/s data rate in the future. Considering this, novel transmission techniques that can increase the date rate with orders of magnitude must be considered. One such example is space-division multiplexing (SDM) fibers. LÄS MER

  4. 19. Respiratory and esophageal morbidity in adults with repaired esophageal atresia

    Författare :Vladimir Gatzinsky; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Esophageal atresia; Long-term outcome; Pulmonary function; Esophageal morbidity; Gastro-esophageal reflux; Dysphagia;

    Sammanfattning : Background: Esophageal atresia (EA) often leads to persistent esophageal and respiratory symptoms, as well as impaired esophageal and lung function in adulthood. The reasons for this, and the connections between symptoms and documented abnormalities, are not fully understood. LÄS MER

  5. 20. Left Ventricular Systolic Dysfunction in 75-year-old Men and Women : A Community-based Study of Prevalence, Screening and Mitral Annulus Motion for Diagnosis and Prognostics

    Författare :Pär Hedberg; Tommy Jonason; Ivar Ringqvist; Eva Nylander; Uppsala universitet; []
    Nyckelord :Medical sciences; Aged; Heart Failure; Ventricular Function; Prevalence; Echocardiography; Electrocardiography; Natriuretic Peptide; Mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Sammanfattning : Reduced performance of the left ventricle to eject blood – left ventricular systolic dysfunction (LVSD) – is a common predecessor of the heart failure syndrome. With or without symptoms, LVSD is associated with a poor prognosis. LÄS MER
