  1. 1. Ohmic Contacts and Thin Film Resistors for GaN MMIC Technologies

    Författare :Anna Malmros; [2011]

    Sammanfattning : Gallium nitride (GaN) based high electron mobility transistor (HEMT) technology has attracted much attention during the last decade which has resulted in a rapid development in material quality and device performance. GaN HEMT microwave electronics are currently finding its applications in wireless communication infrastructure and radar systems. LÄS MER

  2. 2. Development of SiC MESFET Based MMIC Technology

    Författare :Mattias Sudow; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIM capacitor; high power amplifier; limiter; SiC MMIC; SiC MESFET; SiC Schottky; TFR; high level mixer; spiral inductor; via-hole;

    Sammanfattning : A SiC MESFET based MMIC process has been successfully developed. This technology has its main potential in high power microwave circuits. It will offer the benefits of the high integration seen in GaAs MMIC at the same time as it will offer the benefits of the high voltage operation seen in Si LDMOS and Si BJTs. LÄS MER

  4. 4. Erythropoiesis in anemia of rencl failure and malignancy : Studies on erythropoietin, iron, and transferrin receptor : by Soheir Beshara

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Soheir Beshara; Uppsala universitet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical sciences; erythropoiesis; anemia; renal transplantation; prostatic adenocarcinoma; erythropoietin; transferrin receptor; hemorheology positron emission tomography; iron hydroxide sucrose; pharmacokinetics; iron deficiency; 52Fe; 59Fe; red cell utilization; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Internal Medicine; invärtesmedicin;

    Sammanfattning : Erythropoietin (Epo) and iron are essential requirements for erythropoiesis. Serum transferrin receptor (S-TfR) is a marker of total erythropoiesis and tissue iron availability. In patients with renal insufficiency, successful renal transplantation leads to correction of anemia and improvement in erythropoiesis. LÄS MER

  5. 5. Changed iron metabolism and iron toxicity in scrapie-infected neuroblastoma cells

    Detta är en avhandling från Stockholm : Institutionen för neurokemi

    Författare :Sandra Zetterström Fernaeus; Stockholms universitet.; [2005]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; prion disease; oxidative stress; iron metabolism; MEDICINE Chemistry Neurochemistry; MEDICIN Kemi Neurokemi;

    Sammanfattning : Reactions and interactions of iron and oxygen can be both beneficial and detrimental to cells and tissues. Iron is mainly found in our blood where it functions as a mediator in the transport of oxygen to the cells and is further vital for the cellular respiration reducing the oxygen to water. LÄS MER
