Interorganizational relations in industrial systems : a network approach compared with the transaction cost approach
- 1987
-
Reports (other academic/artistic)abstract
- A network approach, as it is developed by some Swedish researchers inindustrial marketing and international business (see e.g. Hägg &Johanson (ed.), 1982 and Hammarkvist, Håkansson & Mattsson, 1982) iscompared with the transaction cost approach associated with OliverWilliamson (e.g. Williamson, 1975, 1979, 1981). The reason we makesuch a comparison is that we often get questions from colleagues inthe scientific community, suggesting that what we try to do is rathersimilar to what the transaction cost approach is doing.

Miljöeffekter av raffinaderiutsläpp i akvatisk miljö.
- 1985
-
Reports (other academic/artistic)abstract
- Rapporten är en genomgång av internationell litteratur om raffinaderiavloppsvattnens kemiska sammansättning, spridning och miljöeffekter. De miljöundersökningar som utförts vid de svenska raffinaderierna under 1970- och 1980-talet har också sammanställts. Sammanställningen avser analyser av avloppsvattnens kvalitet och mängd föroreningar som släpps ut årligen. Dessutom redovisas undersökningar av hydrografiska förhållanden i recipienterna samt avloppsvattnens biologiska effekter. Effekterna på fauna och flora har studerats både i laboratorieundersökningar och i recipientundersökningar. Avslutningsvis diskuteras prognosvärdet av den kemiska och biologiska karakterisering av avloppsvattnet som hittills genomförts.

Effekter på bentisk meiofauna i modellekosystem exponerade för två olika raffinaderiavloppsvatten
- 1987
-
Reports (other academic/artistic)abstract
- Meiofauna dvs djur som kan insamlas på såll med maskstorleken 0.04-1 mm, utgör en grupp som är mycket väl lämpad för biologiska tester av olika substanser. Genom att dessa djur är så små och ofta förekommer med flera miljoner individer per kvadratmeter, kan man här studera effekter på samhällsnivå inom en mycket begränsad yta. Även om den undersökta substansen inte har direkt letala effekter, gör meiofaunans vanligtvis korta generationstid att exempelvis effekter på reproduktionen snabbt kan återspeglas i minskande antal och biomassa.

Protein banding pattern in the Ramalina siliquosa group.
- 1986

In: Lichenologist. - 0024-2829. ; 18:3, s. 231-240

Journal article (peer-reviewed)abstract
- The value of primary chemical compounds correlated with known secondary chemistry and morphological variation within the Ramalina siliquosa group has been investigated. A hundred specimens were collected on two different occasions from 13 different populations on the Swedish west coast during April 1984. Protein extracts were prepared from 27 on secondary constituents identified and morphologically analysed populations. The protein bandings were performed by means of isoelectric focusing. Twenty-two different banding patterns were analysed since two were destroyed during preparation and three others yielded weak patterns. The results indicated that three different banding pattern types could be discerned: type A originated from material containing norstictic acid, stictic acid, norstictic acid in combination with stictic acid and on acid-deficient material; type B originated from material containing salazinic acid or salazinic acid in combination with protocetraric acid; and type C originated from material containing salazinic acid, protocetraric acid, salazinic acid in combination with protocetraric acid or on acid-deficient material. Material of banding type A belonged morphologically to R. cuspidata (Ach.) Nyl. and material of banding types B and C to R. siliquosa (Hudson) A. L. Smith. Seasonal and developmental factors can, however, affect the production of both primary and secondary constituents. Since there are no obvious morphological differences between the different chemical races within R. siliquosa s. str. and as material of salazinic acid in combination with protocetraric acid yielded both type B and type C banding patterns, the results do not support a taxonomy in the R. siliquosa group recognizing more than two species.
