A general mathematical model for the characterization of the dynamic (kinetically labile) association of supramolecular assemblies in solution is presented. It is an extension of the equal K (EK) model by the stringent use of linear algebra to allow for the simultaneous presence of an unlimited number of different units in the resulting assemblies. It allows for the analysis of highly complex dyna

From 1975 through 1995, 45,025 knee arthroplasties were recorded in the prospective Swedish Knee Arthroplasty study. By the end of 1995, 1,135 of 14,772 primary unicompartmental knee arthroplasties (UKA) for localized, mainly medial arthrosis had been revised. The Marmor/Richards and St. Georg sledge/Endo-Link prostheses were used in 65%. Mean age at revision was 72 (71) years. 232 revisions were

Sampling is normally done periodically in time. For linear time invariant systems this leads to closed loop systems that linear and periodic. Many properties can be investigated by considering the behavior of the systems at times that are synchronized with the sampling instants. This leads to drastic simplifications because the systems can be described by difference equations with constant coeffic

Länge ansågs det att fjällig vägglav bara fanns kvar på en enda alm vid Dalby kyrka i Skåne. Efter att trädet höggs ner befarades laven vara borta ur den svenska floran. Den är nu återfunnen på en mur bara några meter från där trädet en gång stod.

Denna bok handlar om naturlighet iförhållande till födsel och föräldraskap - om hur naturligheten positioneras i människans föreställningar kring födseln. Under de tio-femton senaste åren har det skett en förändring i dessa föreställningar från en högteknologisk omsorg med hög riskmedvetenhet till en mer naturlig eller alternativ omsorg. Där tidigare det medicinska tänkandet, som innebar att hälso

This report describes one algorithm to compute exp(A) and one algorithm to compute both exp(A) and its integral. The method used in the two algorithms is finite series approximation, where the matrix is scaled before the expansion. The choice of the number of terms in the series expansion is discussed in detail, and results of numerical investigations performed on the PDP 15/35 computer are presen

Degradation of nitrogen containing organic compounds often leads to formation of ammonium and some low molecular weight organic compounds. The study is focused on degradation of acetonitrile in a sequence of stirred biofilm reactors, where the degradation of acetonitrile into acetic acid and ammonia takes place in the first two reactors. A large fraction of the acetic acid is also degraded in thes

An extensive follow-up study of day- and night-active Macrolepidoptera was performed during 2004 at the Kullaberg Nature Reserve located in the south-western part of Sweden. Butterflies were surveyed in an area of 100 km(2) and night-active moths were trapped in the core area of the reserve. Macrolepidopteran species resident in the area in the 1950s were compared with species resident in the area
