Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- - Allmänheten anser generellt att klimatfrågan är viktig, och förklarar sig beredd att agera både som medborgare och konsumenter. Samtidigt varierar allmänhetens klimathänsyn kraf- tigt mellan olika områden. Social motivation är en stark drivkraft som kan förklara allmänhe- tens motstridiga agerande i klimatfrågan.- Positiva argument som förbättrad luft och högre livskvalitet i städerna, bättre hälsa, ekono- miska besparingar och fokus på djurens välfärd är vanligtvis betydligt mer motiverande än rena klimatargument. En mer begränsad problem- och lösningsinramning kan bidra till att förändringsförslag får ett vidare gehör.- Norm- och handlingsförändringar sker ofta i växelverkan mellan initiativ från allmänheten och styrmedel implementerade av offentliga aktörer.- Moment där människor kan lära av varandra och utbyta erfarenheter, till exempel i praktiska försöks- och pilotprojekt, ökar chanserna till en snabbare och mer omfattande normförändring.- Allmänhetens roll i klimatanpassningsarbetet har inte börjat diskuteras på allvar varken i Skåne eller i övriga Sverige. En dialog bör föras med allmänheten i klimatanpassningsfrå- gorna för att undvika att offentliga och privata anpassningsåtgärder motarbetar varandra.

- Primates have been found to differ widely in their taste perception and studies suggest that a co-evolution between plant species bearing a certain taste substance and primate species feeding on these plants may contribute to such between-species differences. Considering that only platyrrhine primates, but not catarrhine or prosimian primates, share an evolutionary history with the neotropical plant Stevia rebaudiana, we assessed whether members of these three primate taxa differ in their ability to perceive and/or in their sensitivity to its two quantitatively predominant sweet-tasting substances. We found that not only neotropical black-handed spider monkeys, but also paleotropical black-and-white ruffed lemurs and Western chimpanzees are clearly able to perceive stevioside and rebaudioside A. Using a two-bottle preference test of short duration, we found that Ateles geoffroyi preferred concentrations as low as 0.05 mM stevioside and 0.01 mM rebaudioside A over tap water. Taste preference thresholds of Pan troglodytes were similar to those of the spider monkeys, with 0.05 mM for stevioside and 0.03 mM for rebaudioside A, whereas Varecia variegata was slightly less sensitive with a threshold value of 0.1 mM for both substances. Thus, all three primate species are, similar to human subjects, clearly more sensitive to both steviol glycosides compared to sucrose. Only the spider monkeys displayed concentration-response curves with both stevioside and rebaudioside A which can best be described as an inverted U-shaped function suggesting that Ateles geoffroyi, similar to human subjects, may perceive a bitter side taste at higher concentrations of these substances. Taken together, the results of the present study do not support the notion that a co-evolution between plant and primate species may account for between-species differences in taste perception of steviol glycosides.

Tidskriftsartikel (refereegranskat)abstract
- A 14Cr ODS steel was characterized at elevated temperatures with regard to its behavior in small punch and uniaxial creep tests and in low cycle fatigue tests. A comparison of small punch and uniaxial creep tests at 650°C revealed a strong anisotropy of the material when strained parallel and perpendicular to the extrusion direction with rupture times being several orders of magnitude lower for the perpendicular direction. The stress-rupture and Larson–Miller plots show a very large scatter of the creep data. This scatter is strongly reduced when rupture time is plotted against minimum deflection rate or minimum creep rate (Monkman–Grant plot). Fatigue tests have been carried out at 650°C and 750°C. The alloy is cyclically very stable with practically no hardening/softening. Results from the tests at both temperatures can be described by a common power law. An increase in the test temperature has little influence on the fatigue ductility exponent. For a given total strain level, the fatigue life of the alloy is reduced with increasing temperature.
