The growth of environmental consciousness during the recent decades has led to new ethical challenges. Environmental crises have brought to the fore the seldom acknowledged questions of what duties current generations owe towards future generations and what duties human beings owe towards natural entities. A new subdiscipline - environmental ethics - has emerged that especially focuses on these mo

An investigation of Fe II fluorescence by PAR (photoexcitation by accidental resonance) in AG Peg has been carried out using spectra recorded by the IUE satellite. Over 30 active pumping channels caused by PAR are observed and provide an explanation for 180 of the ultraviolet Fe II lines identified in the IUE spectra. The pumping lines are strong nebular lines originating from ionized elements, su

Background. Previous reports of genetic influences on obsessive–compulsive disorder (OCD) symptoms have suggested moderate heritability. Family history studies of co-morbidity have found familial aggregation with tics, especially for early-onset OCD, and familial aggregation with anxiety disorders. Method. Heritability of OCD and familial aggregation of OCD, tics and anxiety disorders were investi

This chapter presents key energy use figures and explores the energy saving potential for electric lighting in office buildings based on a review of relevant literature, with special emphasis on a North European context. The review outlines that an energy intensity of around 10 kWh/m2yr is a realistic target for electric lighting in future low energy office buildings, based on theoretical calculat

Popular Abstract in Swedish Grönsaker andas och efter skörd innebär det att de börjar brytas ner. Broccoli är en grönsak som bryts ner snabbt på grund av sin höga andningshastighet, även kallad respirationshastighet. För att förlänga hållbarheten förpackas den ofta i plastförpackningar med syfte att förhindra nedbrytningen och sänka andingshastigheten. Plastfilmer har olika genomsläpplighet för gaThe modified atmosphere packaging (MAP) of vegetables is used with the aim of prolonging the shelf-life of the packaged produce. The packaging material consists of a permeable film and as a result of the respiration of the produce and gas diffusion through the film, the O2 decreases and the CO2 increases inside the package. This thesis has focused on the MAP of broccoli and the effect of the packa

2,8-Dihalo substituted analogues of Tröger’s base were prepared via the Tröger’s base condensation reaction. These compounds were used as synthetic intermediates for the preparation of otherwise inaccessible functionalized Tröger’s base analogues. Based on 2,8-diiodo-4,10-dimethyl-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine, a mild room temperature protocol for the introduction of terminal func
