We offer an analysis of perceptual intersubjectivity (PI) in terms of two types (symmetric and asymmetric) and three levels: synchronous (SPI), coordinated (CPI) and reciprocal (RPI), defined on the basis of the observable behavior of the participants in a study of (non-verbal) social interaction. We hypothesize that the three levels constitute stages in the development and possibly evolution of h

On the request of Dr Daniel Hellström (Stockholm Water AB), IEA was asked to perform a preliminary investigation of two alternatives for anaerobic digestion operation at Henriksdal’s WWTP in Stockholm, Sweden. The system should be analysed based on parallel or series operation of two existing AD reactors. Moreover, the input load should be based on the current situation and a future scenario (esti

Vocal tract area functions estimated from 38 sets of X-rayed vowel articulations collected from the literature and from new X-ray motion films of English and Arabic speech reveal four constriction locations: along the hard palate, along the soft palate, in the upper pharynx and in the lower larynx. Each location is appropriate for a definable class of vowel qualities, confirming the quantal nature

Popular Abstract in Swedish Selen är ett essentiellt näringsämne som behövs för att upprätthålla flera viktiga funktioner i kroppen, huvudsakligen genom en speciell grupp proteiner som heter selenoproteiner. Det finns minst 25 stycken olika selenoproteiner i människan och flera av dem skyddar kroppen mot oxidation medan vissa andra sköter regleringen av sköldkörtelhormoner. Många selenoproteiners Selenium is a micronutrient that is essential for many important life processes due to the action of the specific selenoproteins containing one or more of the 21st amino acid, selenocysteine. Twenty-five selenoprotein genes have been found in the human genome but the function of many of them is not yet known. Some of the characterised selenoproteins have, however, antioxidant properties. Selenium

In this report, the technical and economical feasibility to produce higher alkanes from bio-glycerol has been investigated. The main purpose of producing this kind of chemicals would be to replace the fossil LPG used in upgraded biogas production. When producing biogas and exporting it to the natural gas grid, the Wobbe index and heating value does not match the existing natural gas. Therefore, th

By growth of Si on substrates that have been pre-patterned by electron-beam induced carbon nano-growth masks, nano-holes form at the Si surface. We have grown self-assembled Ge quantum dots in these holes by ultra high vacuum chemical vapour phase deposition (UHV-CVD). We usually find four dots in each hole. By varying the amount of deposited Ge, we can obtain either four dome-shaped or four pyram

"It is not the eyes that fool you, it’s not the ears that can’t hear It’s the darling conceptions of your time that makes you feel this way" Detta sjunger 1600-talsastronomen Galileo Galilei i denna artikel i FRAMTIDSBOKEN, och artikeln kretsar, precis som alla sex ingående artiklar, kring konceptuella problem knutna till vår tid och ett samhälle som är mer och mer uppkopplat. Dessa dilemman är
