Catalytic properties of oxide nanoparticles applied in gas sensors

A series of gas sensing layers based on indium oxide doped with gold were prepared by using the aerosol technology for deposition as the active contact layer in a metal oxide semiconductor capacitive device. The interaction between the measured species and the insulator surface was quantified as the voltage changes at a constant capacitance of the device. The sensor properties were investigated in

Sätt gräns för privatliv

Efter terrorattackerna i London är det troligt att acceptansen ökar för övervakning av det offentliga rummet. Ytterligare ökade be-fogenheter för polis och underrättelseväsen kan också väntas. Då blir det viktigt att utifrån demokratiska principer definiera vad som är den offentliga respektive den privata sfären, skriver statsvetaren Mikael Sundström vid Lunds universitet.

CCK-dependent pancreatic regulation and pancreatic functional impact on growth in young pigs.

The exocrine pancreas is mainly regulated via neuro-hormonal pathways. CCK-dependent regulatory pathways and CCK-receptor subtype involved seem to differ between mammalian species. The first aim of the thesis was to establish the physiological dose-range for CCK, to further explore the short entero-pancreatic reflex and CCK-receptor subtypes involved in the CCK-mediated regulation of the exocrin
