Beyond the walls of semiconductor fabs: energy intensity of high-grade materials

The increasing semiconductor functionality relies on more complex integrated circuits with higher component densities. Miniaturisation and its implications on resource consumption in semiconductor facilities have been fairly well explored in a number of life cycle assessment (LCA) studies, which show that, in spite of the growing product complexity, resource intensities per product unit are gradua

Reduced CO2 mitigation costs by multi-functional biomass production

The CO2 mitigation cost when biomass replaces fossil fuels depends on several factors, such as the type of fossil fuel replaced, the energy systems involved, induced changes in the biospheric carbon stock, and the intensity and efficiency of the biomass production. Irrigation of energy crops, using nutrient rich municipal wastewater and drainage water, can lead to substantially improved productivi

Social simulator project

The work carried out in the Social Simulator Project focused on development of the social simulator tool. Methods for making use of the tool were also examined. The tool consists of two computer software programs, one for viewing social scenarios and one

Trends in outcomes for very preterm infants in the southern region of Sweden over a 10-year period.

Abstract Aim: To investigate trends in mortality and morbidity in very preterm infants. Methods: Population-based perinatal register; liveborn infants 22 + 0 to 31 + 6 gestational weeks were investigated (time period 1995-2004). Time trends for mortality and common morbidities were explored using logistic regression analyses. Results: Data from 1614 liveborn infants were included. There was an inc

"Hidden"" vibrations in CO: reinvestigation of resonant Auger decay for the C 1s to pi /sup */ excitation

We report an experimental investigation of higher vibrational levels (ν′>2) of the C 1s→π* excitation in CO utilizing resonant Auger electron spectroscopy. These vibrational states are not readily seen in a total yield absorption spectrum, whereas they are shown to be discernable in a partial electron yield spectrum. Furthermore, the nature of the spectator part between EBin=26.5 and 30 eV, being
