Senaste rön om nedbrytning av golvmaterial på betong presenterades på Chalmers före jul, i samband med författarens licentiatseminarium omkring temat "Transportprocesser och reaktioner i belagda betonggolv - olika faktorers inverkan på emission från golvkombinationer". I denna artikel redogörs för de båda viktigaste parametrarna för nedbrytning av limmet, pH-värdet (alkaliteten) och fuktnivån hos
Mycket stora krav ställs på kvaliteten på betongkonstruktionerna till Öresundsförbindelsen. Livslängdskraven är höga samtidigt som miljöförhållandena är tämligen svåra, marin miljö, tösaltning, upprepade fryscykler, allmänt hög fuktnivå, stora vattentryck etc. I denna artikel ges en kort översikt över de krav som ställs på betongen till den 3,7 km långa sänktunnel, som går från Amager till en kons
The scientific STAFF and MALT meetings were created around the turn of the century for scientists engaged in enhancing the role of the 12-lead ECG for detection and quantification of involved myocardium in patients with acute coronary syndrome. These meetings were initially focused on computer processing of data from two single-center databases. The STAFF database was collected in the mid-nineties
The theory of ecologically unequal exchange (EUE) posits that contemporary international trade facilitates a net flow of resources from the peripheral global South to feed industrial processes and capital accumulation in the core North. This situation, it is argued, imperils the development of the South. Trade is a socio-metabolic process which can be analyzed through systemic aggregate approaches
Type 2 diabetes is one of the world’s major challenges today. Over 400 million people around the globe are diagnosed with diabetes and the consequences to the individual patient and health care systems are significant. Diabetes is a chronic disease and the standard treatment including lifestyle changes, metformin and insulin is in many cases not effective enough. New anti-diabetic drugs have been Type 2 diabetes is one of the world’s major challenges today.

The aim of this paper was to examine how useable and inclusive the city is from the perspective of older bicyclists. Methods used were quantitative questionnaires and qualitative focus group interviews. Participants were people aged 65 years or older. The results showed that respondents were fairly satisfied with the transport infrastructure design. However, other road users seemed to complicate c
