Byggnadsnormerna har sedan mitten av 1900-talet gått från att vara ett nationellt framtaget dokument där samtliga normer som regleras ryms i en mindre upplaga om ett hundratal sidor, till de idag internationellt framtagna och nationsanpassade Eurokoderna som omfattar tusentals sidor. I skiftet från BKR till Eurokod reducerades samtliga karakteristiska hållfasthetsvärden för tryck vinkelrätt mot fiberriktningen hos trä. Anledningen till denna reducering är att en ny provningsmetod ligger till grund för hållfasthetsvärdena. CEN EN408 är den provningsmetod som används i Eurokod och utgår ifrån en helt belastad provkroppsom gör att inga närliggande fibrer hjälper till att öka tryckkapaciteten. De karakteristiskavärdena enligt EN408, tillämpas i en annan beräkningsgång än tidigare som i vissa fall är mer komplicerad men som är bättre anpassad till olika lastfall än tidigare normer.

On a request from the water sewage plant Gryaab in Gothenburg a power quality survey was performed. The voltages and currents have continuously been sampled in the incoming 10 kV substation HSP01 from April-August 2008. Power quality measurements were also performed in Gryaabs other 10 kV substation HSP04 fed from HSP01 and at the terminals of the induction motor IN_PU4040 of 1.3 MW which controls one of the four large inflow pumps to the plant. The reason for the latter measurement was due to registered negative transients each time the motor was connected to the grid. The cause of the transients could be explained by the coupling in the substation, the ageing of the motor which could result in damage of the bearings or resonance in the motor circuit which amplifies high frequency harmonics.

Sedan Nacka golfklubb införde källsortering år 2003 har golfklubben funderat över hur deras sortering och avfallshantering egentligen fungerar. I samband med den miljöcertifiering golfklubben ansökt om att få via Golf Environment Organization (GEO) skall ett flertal områden på golfklubben ses över, varav avfallshanteringen är ett av dessa områden.Syftet med examensarbetet är att undersöka hur Nacka golfklubb idag avfallshanterar och ta fram ett underlag för den certifiering golfklubben ansökt om inom det givna området. Underlaget för certifieringen ska baseras på certifieringens krav och rutiner för förbättring ska baseras på kunskap, hantering samt minimering. De metoder som använts är litteraturstudier, intervjuer, studiebesök samt en analys utifrån Sustainable Development Records (SDR).Resultatet av SDR gav en generell bild av golfklubbens effektivitet, sparsamhet och marginal. Genom SDR kan golfklubben i framtiden fortsätta att mäta och jämföra sina resultat för att se om verksamheten går mot en mer hållbar utveckling och avfallshantering men för att göra detta måste en grundligare undersökning i framtiden genomföras i samband med en avfallsrevision.Utifrån det rutiner golfklubben har rekommenderas ett flertal förändringar för att golfklubben ska få en bättre standard inom sin avfallshantering.
