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

Two monoclonal antibodies (mAb) CB268 and CII-C1 to type 11 collagen (CII) react with precisely the same conformational epitope constituted by the residues ARGLT on the three chains of the CII triple helix. The antibodies share structural similarity, with most differences in the complementarity determining region 3 of the heavy chain (HCDR3). The fine reactivity of these mAbs was investigated by s

OBJECTIVES: To study the background and the working and socio-economic conditions, and the prevalence of some sexually transmitted diseases (STDs), among street and sex club female Latvian prostitutes. STUDY DESIGN: Structured in-depth interviews, as well as clinical examination and laboratory tests for gonorrhea, syphilis, bacterial vaginosis, trichomoniasis, ectoparasites and HIV-infections. RES

A unified approach is given which allows one to construct examples of all three cases resulting from a generalization of the classical Weyl limit point limit circle analysis, for differential equations as well as for difference equations.

Background: Milk protein, in particular the whey fraction, has been shown to display insulinotrophic properties in healthy persons and persons with type 2 diabetes. In parallel to the hyperinsulinemia, a pronounced postprandial rise of certain amino acids and of glucose-dependent insulinotrophic polypeptide (GIP) was observed in plasma. Objective: The objective of the study was to determine to wha

The polyamines spermine and spermidine inhibit L-type Ca2+ channels in whole-cell recordings from guinea-pig ileum cells (Gomez and Hellstrand, Pflugers Arch, 430:501-507, 1995 [4]). To study whether they modulate channel activity under physiological conditions, we further investigated their actions on Ca2+ channels and the effects of altered cellular polyamine contents. In inside-out patches, spe
