  1. 6. Deposition and Resolution of AA Amyloid

    Författare :Sofia N. Nyström; Gunilla T Westermark; Christoph Röcken; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; AA-amyloid; autophagy; resolution; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi;

    Sammanfattning : Amyloidosis is a group of protein misfolding diseases characterized by extracellulardeposition of fibrillar protein aggregates. Today more than 25 different human amyloidogenicproteins have been identified, causing a variety of pathological conditions that includeAlzheimer’s disease, type 2 diabetes and prion diseases.

  3. 7. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

    Författare :Sanny Syberfeldt; Sten Andler; Jörgen Hansson; Sang H. Son; Alejandro Buchmann; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution; Computer science; Datalogi; Teknik;

    Sammanfattning : In this thesis a replication protocol - PRiDe - is presented, which supports optimistic replication in distributed real-time databases with deterministic detection and forward resolution of transaction conflicts. The protocol is designed to emphasize node autonomy, allowing individual applications to proceed without being affected by distributed operation. LÄS MER

  4. 8. Asymmetric transformation of ß- and γ-functionalized alcohols : Study of combined ruthenium-catalyzed racemization and enzymatic resolution

    Författare :Annika Träff; Jan-Erling Bäckvall; Reko Leino; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kinetic resolution; dynamic kinetic resolution; kinetic asymmetric transformation; dynamic kinetic asymmetric transformation; enzyme catalysis; racemization; asymmetric synthesis; chlorohydrin; cyano acetate; amino alcohol; metalloenzyme; bifunctional catalytic system; Organic synthesis; Organisk syntes; organisk kemi; Organic Chemistry;

    Sammanfattning : The major part of this thesis describes the asymmetric synthesis of β- and γ-amino alcohols through the combination of ruthenium catalyzed racemization and enzymatic kinetic resolution. The dynamic kinetic resolution, DKR, protocol for chlorohydrins was improved by employing Bäckvall’s catalyst, which is a base activated racemization catalyst, in combination with Burkholderia cepacia lipase.

  5. 9. Ultra-Wideband Time Domain Measurement Systems for Microwave Tomography

    Författare :Xuezhi Zeng; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Time DomainMeasurement; Ultra-Wideband; EquivalentTime Sampling; Real Time Sampling; Microwave Tomography; Measurement Error; Frequency Domain Measurement;

    Sammanfattning : As a potential imaging modality for biomedical applications, microwave tomography has attracted a lot of interests in recent years. With microwave tomography, microwave signals are transmitted into the biological tissues and the scattered fields are recorded. LÄS MER

  7. 10. Synchrophasor Applications and their Vulnerability to Time Synchronization Impairment

    Författare :Muhammad Shoaib Almas; Luigi Vanfretti; Mario Paolone; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware-in-the-loop; phasor measurement units; real-time simulation; time synchronization; wide-area monitoring protection and control.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Recent years have seen the significance of utilizing time-synchronized, high resolution measurements from phasor measurement units (PMUs) to develop and implement wide-area monitoring, protection and control (WAMPAC) systems. WAMPAC systems aim to provide holistic view of the power system and enable detection and control of certain power system phenomena to enhance reliability and integrity of the grid. LÄS MER
