This report deals with the maritime transport system of packaged dangerous goods (PDG) and principles of risks of marine accidents/incidents involving dangerous goods. The report has been part of the Safe and Reliable Transport Chains of Dangerous Goods in the Baltic Sea Region (DaGoB) project and the author’s own research. The main aims of the DaGoB project included: a) improve co-operations at v
The aim of this article is to briefly explore how quartz-rich sandstone might have been perceived by TRB societies. Using the senses as a point of departure, it discusses how sandstone was selected for grinding stones and for dry walling in megaliths, emphasizing the significance of the visual as well as the mechanical properties of the material. The article also acknowledges the complexity of th
Popular Abstract in Swedish Ultraljudets roll vid utredning av postmenopausalblödning Målsättning Att ta reda på hur ultraljud bäst används vid utredningen postmenopausalblödning för att individualisera och optimera diagnostiken och behandlingen. Värdet av gråskaleultraljud med eller utan koksaltsinfusion (hydrosonografi) och av "Power Doppler"-ultraljud undersöktes med avsikt att ta reda på om The aim of this thesis was to investigate how ultrasound can be used in the diagnostic work-up of women with post-menopausal bleeding (PMB) to optimise and individualise their management. The thesis is based on six studies comprising post-menopausal women with (Study I-VI) and without (Study VI) abnormal bleeding. The clinical value of conventional ultrasound, with or without saline infusion (hyd
An energy system that relies on fossil fuel is not sustainable. Emissions, such as carbon dioxide, nitric oxide and corpuscles, affect the climate and pollute the air. Furthermore, the supply of oil, coal and natural gas is located a few places worldwide, which can give rise to geopolitical conflicts for access to these areas. This is not a local issue for Tjörn, nor even a national issue for Swed
The present thesis presents pressure-temperature and geochronological data from the high-grade mafic rocks from the Southwest Swedish Granulite Region, which forms part of the southwestern Baltic Shield. The region is characterized by variably deformed and migmatized granitic to intermediate gneisses, metabasites and charnockites metamorphosed in granulite and upper amphibolite facies. The peak m
A 50-MS/s two-step flash-ΔΣ time-to-digital converter (TDC) using a 2-channel time-interleaved time-domain register with an implicit adder/subtractor demonstrates a 3rd order noise-shaping. The TDC is fabricated in 40-nm CMOS and consumes 1.2 mA from a 1.1 V supply. At frequencies below 1.25 MHz, the TDC error integrates to 103 fsrms, which is equal to an equivalent resolution of 1.6 ps.
Increased energy efficiency at the point of end-use is a key strategy for addressing a range of energy related problems, including greenhouse gas emissions. There are energy efficiency alternatives that can be implemented at low cost,and perhaps with some cost savings – these activities offer no-regrets opportunities for climate change mitigation. In addition, high levels of end-use energy efficie
