The Membrane-Spanning Domain of Complex I Investigated with Fusion Protein Techniques

Popular Abstract in Swedish När vi äter kolhydrater, fett, protein och andra näringsämnen sker kemiska reaktioner i kroppen som kan liknas vid dom som sker när man eldar en brasa. Vid förbränning reagerar kolhydrater med syre och bildar koldioxid och vatten. Denna förbränning frigör den energi som funnits lagrad i kolhydraterna, i brasan i form av värme, och i kroppens celler omvandlas den till keNADH:quinone oxidoreductase, or complex I, is a large, complex and poorly understood bioenergetic enzyme in the respiratory chain of living organisms. The enzyme has a conserved core structure, comprising fourteen protein subunits: Seven subunits protrude from the membrane and contain a flavin prosthetic group and eight iron-sulfur clusters that guide electrons from the oxidation of NADH towards t

A 65nm CMOS 282uW 915MHz direct conversion receiver front-end

Abstract in UndeterminedThis paper presents an inductorless ultra-low power radio receiver front-end intended for applications such as sensor networks and medical implants. It consists of low noise amplifier, quadrature mixer, and a frequency divider for the generation of quadrature local oscillator signals. The power consumption is just 282μW from a 0.9V supply when it operates in the 915 MHz ISM

Definition of landscape erosion units using a structural classification OASIS of Landsat TM satellite imageries, case study Lebanon.

Soil erosion by water is a major cause of landscape degradation in semi-humid to semi-arid Mediterranean environments. Terrain particularly susceptible to the phenomenon witness a combination of erosive soil, unconsolidated rock type, steep slope, high rainfall intensity, active tectonic movement, rapid land use change and intense human interference. Current erosion models (e.g. USLE, RUSLE) are b
