Fifty knees scheduled for a total knee prosthesis were randomized in two groups. Both groups had a noncemented fixation of the porous-coated implants but one group received a prosthesis with ceramic coating on the porous surface of the implant. The knees were evaluated with RSA technique regarding micromotion the first two years. There were less micromotion in the coated group. The results indicat
The intra-molecular, proton-coupled electron transfer from a tyrosine residue to covalently linked tris-bipyridine ruthenium(III) complexes in aqueous solution (Ru-III-TyrOH --> Ru-II-TyrO(.) + H+) is studied in two complexes. The Ru-III-TyrOH state is generated by laser flash-induced photo-oxidation in the presence of the electron acceptor methyl viologen. The reaction is shown to follow either a
A novel surface protein of the bacterial species Moraxella catarrhalis that displays a high affinity for IgD (MID) was solubilized in Empigen and isolated by ion exchange chromatography and gel filtration. The apparent molecular mass of monomeric MID was estimated to approximately 200 kDa by SDS-PAGE. The mid gene was cloned and expressed in Escherichia coli. The complete mid nucleotide gene seque
This paper explores the quasi-deformation scheme devised in [1, 3] as applied to the simple Lie algebra sl(2)(F) for specific choices of the involved parameters and underlying algebras. One of the main points of this method is that the quasi-deformed algebra comes endowed with a canonical twisted Jacobi identity. We show in the present article that when the quasi-deformation method is applied to s
Action plan for the conservation of Psora vallesiaca Psora vallesiaca is red-listed in Sweden and assigned to the category Critically Endangered (CR). In Sweden it is known from one locality on Öland where it grows in a small population of about 30 individuals. In the spring of 2006, four new localities were discovered on Gotland. The main distribution of Psora vallesiaca streches from the Mediter
In this study, we describe the expression and function of CD40, a TNF receptor family member, in cervical carcinomas. CD40 was present at very low levels in normal cervical epithelium but was overexpressed in human papillomavirus-infected lesions and advanced squamous carcinomas of the cervix. The stimulation of CD40-positive cervical carcinoma cell lines with soluble CD40L (CD154) resulted in act
This thesis presents experimental investigations of local heat transfer and detailed flow measurements in ribbed rectangular ducts and impinging jets. The advanced measurement methods, Liquid Crystal Thermography (LCT) and Particle Image Velocimetry (PIV) are adopted to provide full field characteristics. The work consists of two parts, regarding rib-roughened rectangular ducts and impinging slot
No surveillance is recommended after radical excision of low-risk adenomas (pedunculated adenoma irrespective of size, sessile adenoma < or = 10 mm, number < or = 2. An endoscopic check-up is recommended 3-6 months after radical excision of high-risk adenomas (sessile adenoma > 10 mm, number > or = 3), as well as after excision of a pedunculated or a sessile adenoma with an unclear resection margi
Agnostids afford the best means of correlating Cambrian strata, and they are widely used for intercontinental correlations. They are most common in open-marine deposits and reached a maximum diversity during the Middle and early Late Cambrian. About twenty species of agnostids are known from the Upper Cambrian of Scandinavia. Lotagnostus? mystacinus Tjernvik, 1953 is a rare agnostid from the Upper
Popular Abstract in Swedish Denna avhandling är resultatet av ett doktorandprojekt vid Kvartärgeologiska avdelningen, Lunds Universitet. Syftet med undersökningen var att rekonstruera vegetations- och klimatförändringar under de senaste 10 000 åren i Torneträskområdet i norra Sverige. Resultatet bygger på analyser av pollen och växtmakrofossil från 6 sjöar belägna på olika höjd över havet (370-999The aim of this study was to reconstruct the Holocene vegetation history and the climate changes in a subarctic area. The results are based on pollen and macrofossil records from six lakes in the Torneträsk area. The lakes are situated at altitudes between 370 and 999 m a.s.l., along a transect from the boreal pine-birch forest to the alpine tundra with heath vegetation. The chronology in each lak
Popular Abstract in Swedish Områden som är kontinuerligt utsatta för vinderosion löper stor risk för att erhålla en försämrad jordkvalitet eftersom vinderosion innebär en utsållning av fina fraktioner och humus från jordmånen. För att vinderosion ska inträffa krävs en kombination av vissa väder- och markförhållanden. Flera av dessa är direkt relaterade till klimatet, t ex vindhastighet och jordfukWind erosion is a serious threat to soil resources as it causes depletion of the fine fractions that may result in a less fertile soil. Wind erosion encompasses several processes of which many are related to climate variables. To date, there is little work performed on how wind erosion relates to climate and climate change. In this thesis, atmospheric circulation and wind erosion were analysed to
Abstract Introduction Carpal tunnel syndrome (CTS) is thought to be due to compression of the median nerve in the carpal tunnel. It is known that carpal tunnel pressures are elevated in wrist postures of flexion and extension and in those patients with CTS. Classic symptoms of CTS include night waking with pain, tingling, and numbness. These classic symptoms stimulated our interest in the relation
Background: The authors have identified and studied a large kindred in which frontotemporal dementia (FTD) is inherited as an autosomal dominant trait. The trait has been mapped to the pericentromeric region of chromosome 3. Methods: The authors report on the clinical, neuroimaging, neuropsychological, and pathologic features in this unique pedigree collected during 17 years of study. Results: Twe
I allt fler länder börjar en brandteknisk klassificering av byggnadsdelar tillåtas som bygger på en analytisk behandling i stället för på resultat ac ugnsprovningar enligt ISO 834. I Sverige godtas sedan lång tid en analytisk branteknisk dimensionering av bärande och avskiljande konstruktioner som ett alternativ till standardiserad termisk påverkan enligt ISO 834. En väsentlig förutsättning för en
We study the geodesic exponential maps corresponding to Sobolev type right-invariant (weak) Riemannian metrics mu((k)) (k >= 0) on the Virasoro group Vir and show that for k >= 2, but not for k = 0, 1, each of them defines a smooth Frechet chart of the unital element e is an element of Vir. In particular, the geodesic exponential map corresponding to the Korteweg - de Vries (KdV) equation ( k = 0)
Popular Abstract in Swedish Rättvisekriterier och andra etiska aspekter spelar en stor roll i svensk sjukvård. De ingår t ex i målformuleringen i hälso- och sjukvårdslagen ("Målet för hälso- och sjukvården är en god hälsa och en vård på lika villkor för hela befolkningen.", §2). Läkare och andra beslutsfattare påpekar regelbundet vikten av moraliska värderingar, och befolkningen i gemen torde delaEquality of access may be defined and operationalised in several ways. Paper I, 'Equality of access. Definitions and policy implications', proposes a theoretical outline of possible definitions of equal access, of the policy measures needed to attain equality and of their consequences. The health economic literature proposes two main definitions of equal access. Equal access prevails either when i
We present a detailed analysis of time-resolved optical spectra of the ZZ Ceti white dwarf, HS 0507+0434B. Using the wavelength dependence of observed mode amplitudes, we deduce the spherical degree, , of the modes, most of which have . The presence of a large number of combination frequencies (linear sums or differences of the real modes) enabled us not only to test theoretical predictions but al
