- Colour and light have largely been considered as belonging to two different fields of knowledge, having disparate theoretical, terminological and methodological traditions. This creates a ground for misunderstandings and obstructs a fruitful interdisciplinary and interprofessional collaboration. A survey over international research literature from 2006 -2011 shows that there has been only little research on the spatial interaction between colour and light, but that the interest for this area has recently increased. The interdisciplinary Nordic research project SYN-TES: Human colour and light synthesis. Towards a coherent field of knowledge was carried out during 2010-11. Colour and light experts from Nordic universities and companies investigated different aspects of the spatial interaction between colour and light and its importance for human beings. This paper deals with the general learnings from the process. Specific results are presented in other papers at this conference.

- Background: Alcohol dependence has been associated with reduced function of serotonin, dopamine as well as noradrenaline activities in several neuroendocrine studies. To our knowledge, there is, however, no study investigating all these 3 systems with the use of neuroendocrine methods in one and the same alcohol-dependent individual. Methods: Alcohol-dependent individuals (n=42) and controls (n=28) participated in the neuroendocrine test series. Central serotonergic neurotransmission was assessed by the prolactin (PRL) response to citalopram (CIT). The postsynaptic DRD2 function was measured by the growth hormone (GH) response to apomorphine (APO) and the postsynaptic α2-adrenoceptor function by GH response to clonidine (CLON). Results: In the alcohol-dependent individuals, the PRL concentrations were significantly lower at the time points 240minutes and 300minutes after CIT administration and mean delta PRL value was significantly reduced by 45% in comparison with controls. There were no significant differences in APO-GH and CLON-GH concentrations at any time points or in mean delta GH values between the groups. An impaired monoaminergic profile, including all 3 systems, was significantly more frequent in alcohol-dependent individuals than controls (43% vs. 6% respectively). Conclusions: The monoaminergic dysfunction was restricted to an impairment of the serotonergic system, suggesting that this system is especially vulnerable to long-term and excessive alcohol consumption. Moreover, impaired monoaminergic profiles, including low responses in 2 or 3 systems, were more frequently observed in alcohol-dependent individuals than in controls. Such impaired profiles may be of clinical importance, but further studies are needed.

SYN-TES 2010-2011 Interdisciplinära studier om färg – ljus – rum
- 2012
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Det tvärvetenskapliga projektet SYN-TES. Människa, färg och ljus. Syntetisering för ett sammanhållet kunskapsfält har pågått på Konstfack under 2010-2011, med finansiering från KK-stiftelsen (ref. nr 2009/0195). Projektet har omfattat ett femtontal nordiska färg- och ljusspecialister från företag och olika akademiska discipliner. Alla deltagarna har dessutom arbetat med annan forskning och/eller utvecklingsarbete om ljus- och/ eller färgfrågor. I arbetet med SYN-TES har gruppen regelbundet hållit interna semina- rier där olika kunskapstraditioner kunde närmas varandra och där gruppen gemensamt formulerade grunderna för ett sammanhållet kunskapsfält som innefattar både färg och ljus. I anslutning till detta har det genomförs ett antal under- eller sidoprojekt kring avgränsade frågeställningar, delvis med finansiering från Energimyndigheten (projekt nr 32266-1 och 34528-1)Det övergipande syftet var att skapa förutsättningarna för ett sammanhållet kunskapsfält som innefattar både färg och ljus, ur ett mänskligt perspektiv. I denna rapport sammanfattar vi huvuddragen i denna ”syntetisering”, med tonvikt på frågeställningar och processer. De mer konkreta resultaten av seminarier och subprojekt redovisas i en serie separata rapporter.

Photoluminescence photoresponse from InSb/InAs-based quantum dot structures
- 2012

Ingår i: Optics Express. - : Optical Society of America. - 1094-4087. ; 20:19, s. 21264-71

Tidskriftsartikel (refereegranskat)abstract
- InSb-based quantum dots grown by metal-organic vapor-phase epitaxy (MOVPE) on InAs substrates are studied for use as the active material in interband photon detectors. Long-wavelength infrared (LWIR) photoluminescence is demonstrated with peak emission at 8.5 μm and photoresponse, interpreted to originate from type-II interband transitions in a p-i-n photodiode, was measured up to 6 μm, both at 80 K. The possibilities and benefits of operation in the LWIR range (8-12 μm) are discussed and the results suggest that InSb-based quantum dot structures can be suitable candidates for photon detection in the LWIR regime.
