   Sammanfattning : The effects of cypermethrin, copper and glyphosate on the endocrine system and subsequent response to female pheromones were investigated in mature male brown trout (Salmo trutta) parr.  Responses measured were the amount of strippable milt, blood plasma levels of both an androgen (11-ketotestosterone (11-KT)) and a progestin (17α,20β-dihydroxy-4-pregnen-3-one (17,20b-P)), and behavioural changes.

4. 13. Theoretical studies of blue copper proteins

   Författare :Mats H M Olsson; Beräkningskemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum chemistry; metal-thiolate bonds; axial ligation; electron transfer proteins; reduction potential; reorganisation energy; Cu II ; Cu I ; strain; Induced-rack theory; Entatic state theory; cytochrome c oxidase; CuA; nitrite reductase; azurin; Blue copper proteins; plastocyanin; B3LYP; CASPT2; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

   Sammanfattning : In this thesis, a critical investigation is presented about the role of mechanical strain for the electron-transfer properties of the blue copper proteins. It has been found that the structure of a realistic model complex of the oxidised blue-copper active site, optimised in vacuum with the B3LYP method, has the same trigonal cupric geometry as in the protein.

5. 14. Cu(I) stabilizing polymers for marine anti-fouling applications

   Författare :Alireza Movahedi; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; coordinating polymers; copper; anti-fouling coatings; CuAAC; triazole; epoxide.; polymer functionalization; click chemistry;

   Sammanfattning : The growth of marine organisms on immersed surfaces in seawater is known as biofouling and causes several problems for marine transportation. The need to combat fouling is thus of great importance. Copper has to be used in extreme amounts to act as an efficient biocide. LÄS MER

7. 15. Innovationsmiljöer i bronsålderns samhälle och idévärld : kring ny teknologi och begravningsritual i Västergötland

   Författare :Eva Weiler; Umeå universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; megaliths; bronze; moulds; technology; innovation; communication; distribution; ideology; personified symbols; two-dimensional pictures; burial rites; Fornlämningar; Gravar; Bronsarbeten; Gravskick-- Sverige -- Västergötland; Sverige-- Västergötland -- Småland -- Skåne -- Halland;

   Sammanfattning : The aim of this thesis is to elucidate on the factors that lay behind general occurrences in society that diversely develop according to the variance in social and cultural backgrounds. The thesis encompasses the period between 2000-500 BC and concentrates on the effects of the introduction of a new technology (metal working) and new burial rites on the society in SW Sweden (Västergötland).
