Temperature and soil C decomposition – synthesis of current knowledge and a way forward

The response of soil organic matter (OM) decomposition to increasing temperature is a critical aspect of ecosystem responses to global change. The impacts of climate warming on decomposition dynamics have not been resolved due to apparently contradictory results from field and lab experiments, most of which has focused on labile carbon with short turnover times. But the majority of total soil carb

Investigation of Reconfigurability for a Stacked Microstrip Patch Antenna Pattern Targeting 5G Applications

A pattern reconfigurable stacked microstrip patch antenna is presented for 60GHz central frequency. The antenna reconfigurability is realized using shorting pins in the antenna radiating aperture. Investigation is presented for different shorting pins locations. Influence on the antenna radiation pattern and return loss is studied. Measurement results for the antenna prototype agree with simulatio

The Bowu zhi: An Annotated Translation

This dissertation has a two-fold purpose. Firstly, it provides an annotated translation of the full text of the Bowu zhi by Zhang Hua (232-300), an intriguing early mediaeval work that contains passages which throw interesting light on a number of fields in mediaeval Chinese scholarship and the development of traditional Chinese science. As reference to the Bowu zhi is rendered difficult by the pa

Study of a three-phase claw-to-claw pole machine

A three-phase electrically magnetized synchronous machine has been studied. The peculiarity of the motor is that the magnetization coils are locating on the stationary part and no sources of magnetic energy are introduced in the moving part. The conventional electrical coupling via slip rings has been replaced with a magnetic coupling via additional air-gap. The idea of the design is to investigat

Tillit i arbetslivet – några nedslag

Följande texter är tidigare publicerade som blogginlägg på Cybernormer.se samt digitalsociety.se och kretsar kring arbetslivets förändring i en digital kontext. Tillitsbegreppet är centralt här och texterna diskuterar exempelvis kontroll och övervakning - eller "employee monitoring" - kontra ökade frihetsgrader för anställda att styra över sina arbetstider.

Blood-brain barrier permeability in rats exposed to electromagnetic fields used in wireless communication

iological effects of radio frequency electromagnetic fields (EMF) on the blood-brain barrier (BBB) have been studied in Fischer 344 rats of both sexes. The rats were not anaesthetised during the exposure. All animals were sacrificed by perfusion–fixation of the brains under chloralhydrate anaesthesia after the exposure. The brains were perfused with saline for 3–4 minutes, and thereafter perfusion
