  1. 1. Surveillance of Antibiotic Consumption and Antibiotic Resistance in Swedish Intensive Care Units

    Författare :Marcus Erlandsson; Håkan Hanberger; Nils Smith-Erichsen; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacterial Antibiotic resistance; Antibiotic Consumption; ICU; Surveillance programme; Multi drug resistance; Pseudomonas aeruginosa; ICU demography; Infectious diseases; Infektionssjukdomar;

    Sammanfattning : Introduction: Nosocomial infections remain a major cause of mortality and morbidity. The problem is most apparent in intensive care units (ICUs). Most ICU patients are compromised and vulnerable as a result of disease or severe trauma. One in ten people admitted to hospital is given an antibiotic for infection. LÄS MER

  3. 2. "Who are you to tell us our history?" : kultur och religion i hawaiianers möte med amerikansk mission

    Författare :Kristina Hellner Taylor; Centrum för teologi och religionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; de-colonization; conflict; colonial; Hawaiian medicine; culture; hula; resistance; Hawaii; knowledge; education; sexuality; social relationships; dress; body; civilization; behavior; civilizational colonialists; Hawaiian culture; Hawaiian history; American missionaries; de-familiarization; Hawaiian Movement; history of religions; anthropology; history; comparative religion;

    Sammanfattning : The life and history of the Hawaiians has been documented ever since the contact with Western adventurers at the end of the 18th century. In connection with the arrival of American missionaries in 1820, these missionaries introduced and established a puritanical doctrine and method of communicating knowledge by way of the written word.

  4. 3. Run-Up Transient Analysis for Salient Pole Wound Field Synchronous Motors : Field winding and power electronics implications for a smoother and cooler asynchronous start

    Författare :Roberto Felicetti; Urban Lundin; Andreas Binder; Uppsala universitet; []
    Nyckelord :apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency; asynchronous start; run-up; torque ripple; reluctance torque; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Salient Pole Wound Field Synchronous Machines have better efficiency at full load than asynchronous machines of the same capability. Moreover, where asynchronous machines need inherently to draw a magnetizing current from the grid, Salient Pole Wound Field Synchronous Machines can work efficiently at unity power factor. LÄS MER

  5. 4. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics

    Författare :Roberto Felicetti; Urban Lundin; Jon Kjellin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency;

    Sammanfattning : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. LÄS MER

  7. 5. Stainless Steel Corrugated Web Girders for Composite Road Bridges: Concept Evaluation and Flange Buckling Resistance

    Författare :Fatima Hlal; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Investment cost; Genetic algorithm; Duplex stainless steel; LCC; Corrugated web; Flange buckling resistance; Optimization; Composite bridges; LCA; Road bridges;

    Sammanfattning : Achieving a sustainable bridge design requires careful consideration of economic viability and environmental impact over the entire lifespan of the structure. While stainless steel is recognized for its excellent life cycle performance, its high cost prevents it from being used to a larger extent in bridges. LÄS MER
