Defects on endoanal ultrasound and anal incontinence after primary repair of fourth-degree anal sphincter rupture: a study of the anal sphincter complex and puborectal muscle

Objectives To perform three-dimensional endoanal ultrasound (EA US) after primary repair of fourth-degree anal sphincter rupture (ASR) and correlate the sonographic defects with anal incontinence (AI); to measure the axial and sagittal thickness and angle of the puborectal muscle (PRM) as well as the length of the anal canal, and then correlate these measures with AI; and to assess the interobserv

In-plane visibility of lesions using breast tomosynthesis and digital mammography

Purpose: The purpose of this work was to evaluate the visibility of simulated lesions in 2D digital mammography (DM) and breast tomosynthesis (BT) images of patients. Methods: Images of the same women were acquired on both a DM system (Mammomat Novation, Siemens Healthcare, Erlangen, Germany) and a BT prototype system adapted from the same type of DM system. Using the geometrical properties of the

Strength Design Methods for Laminated Glass

In this thesis, methods for efficiently determining stresses in laminated glass structures are developed and tested. The laminated glass structures comprise both bolted and adhesive joints. A recently developed finite element is suggested to be suitable for the modeling of laminated glass structures. The element is implemented and tested. It is proven by means of a simple test example that the ele

Life Satisfaction and the Oldest-Old. Results from the longitudinal population study "Good Aging in Skåne".

The overall aim of this thesis was to study life satisfaction (LS) and factors associated to LS in the group aged 78 and above. As an aid in interpreting the findings, Baltes’ and Baltes’ theory of selective optimisation with compensation (SOC) was used. All four studies included the same studypopulation who were followed for three years in the study Good Aging in Skåne, a national, randomized, po

Extremum seeking of dynamical systems via gradient descent and stochastic approximation methods

This paper examines the use of gradient based methods for extremum seeking control of possibly infinite-dimensional dynamic nonlinear systems with general attractors within a periodic sampled-data framework. First, discrete-time gradient descent method is considered and semi-global practical asymptotic stability with respect to an ultimate bound is shown. Next, under the more complicated setting w

TAR-DNA binding protein-43 and alterations in the hippocampus

Immunocytochemistry for transactive response binding protein-43 (TDP43) was assessed in the granular cell layer of the dentate gyrus in 250 cases displaying hippocampal pathology identified by haematoxylin-eosin staining. 18%, nearly one in five displayed TDP43 immunoreactive pathology in the granular cell layer of hippocampus. This percentage increased to 43% when only subjects with hippocampal p

Stereoisomeric analysis of 6,10,14-Trimethylpentadecan-2-ol and the corresponding ketone in wing extracts from African Bicyclus butterfly species

Gas chromatography (GC) and mass spectrometry (MS) were used to determine the stereoisomeric compositions of 6,10,14-trimethylpentadecan-2-ol and 6,10,14-trimethylpentadecan-2-one in wing extracts from 17 Bicyclus butterfly species from different regions of Africa. All samples were purified using solid phase extraction (SPE). Since some species contained both alcohol and ketone, these were separat

Charmonium and e(+)e(-) pair photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at root s(NN)=2.76 TeV

The ALICE Collaboration at the LHC has measured the J/psi and psi' photoproduction at mid-rapidity in ultra-peripheral Pb-Pb collisions at root s(NN) = 2.76 TeV. The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 mu b(-1). The cross secti

Theoretical and experimental comparison of SnPc, PbPc, and CoPc adsorption on Ag(111)

A combination of normal-incidence x-ray standing-wave (NIXSW) spectroscopy, x-ray photoelectron spectroscopy (XPS), scanning tunneling microscopy (STM), and density-functional theory (DFT) has been used to investigate the interaction of a number of phthalocyanine molecules (specifically, SnPc, PbPc, and CoPc) with the Ag(111) surface. The metal-surface distances predicted by the DFT calculations f

Multivariate analysis of selected metal ion transport through a hollow-fiber supported liquid membrane device used for passive sampling monitoring

A hollow fiber supported liquid membrane module using one single fiber impregnated with a mixture of 1,10-dibenzyl-1,10-diaza-18-crown-6 and bis(2-ethylhexyl)phosphate dissolved in hexylbenzene was used for passive sampling of ppb levels of Pb(II), Cu(II), Zn(II), Mn(II), Ni(II), and Cd(II) in water. The target ions were simultaneously transported and preconcentrated into a citric acid acceptor so

Video assisted gastrostomy in children

Popular Abstract in Swedish Att kunna äta och dricka via munnen är för de allra flesta barn en självklarhet och grunden för en god tillväxt och välmående. Problem uppstår när barnen av någon anledning inte kan svälja eller har ett så stort behov av näring pga en bakomliggande sjukdom att de basala behoven inte kan tillfredsställas på normalt sätt. För att underlätta tillmatning under en kortare pChildren with severe diseases can be provided nutritional support through a gastrostomy if needed. At the Department of Paediatric Surgery in Lund we have used the Video Assisted Gastrostomy (VAG) procedure since 1994 when establishing gastrostomies. In this thesis, children with different diseases, who all had undergone the VAG procedure, were studied in five different clinical studies. Postopera

A perspective on the characterization of colloids and macromolecules using asymmetrical flow field-flow fractionation

Asymmetrical flow field-flow fractionation (AF4) is rapidly becoming a technique of choice for the separation and characterization of complex materials. It is capable of fractionating samples over a wide size (similar to 2 nm to 50 mu m in diameter) and molecular weight range (10(3)-10(10) g/mol). It offers gentle, low shear, low pressure separation conditions which are essential to preserve the s

Doing Ethnographic Research in Chinese Families: Reflections on Methodological Concerns from Two Asian Cities

This paper compares and contrasts the ethnographic practices of two non-native researchers – a Singaporean researcher studying families in mainland China and a Swedish researcher studying Chinese families in Singapore. A novel conceptual frame of ‘radius of observation positions’ has been proposed to explicate the extent of intrusion and intimacy to which researchers may venture in the private fam

Crystal Phases in III-V Nanowires: From Random Toward Engineered Polytypism

III-V nanowires (NWs) are promising for a wide range of applications, ranging from optics to electronics, energy, and biological sensing. The structural quality of NWs is of paramount importance for the performance of such future NW-based devices. Random structural defects and polytypism occur naturally in semiconductor NWs, but progress both on the theoretical understanding and experimental contr

Surface proteins of Finegoldia magna interacting with the human host

Finegoldia magna is a Gram-positive anaerobe and a member of the normal human microflora. This bacterium is also an opportunistic pathogen and isolated from ~10% of all anaerobic infections. Reoccurring taxonomical changes and the anaerobic growth have contributed to the neglect of F. magna. The present thesis describes the identification and characterization of two novel surface proteins of F. ma

Properties of long gamma-ray bursts from massive compact binaries.

We consider the implications of a model for long-duration gamma-ray bursts in which the progenitor is spun up in a close binary by tidal interactions with a massive black-hole companion. We investigate a sample of such binaries produced by a binary population synthesis, and show that the model predicts several common features in the accretion on to the newly formed black hole. In all cases, the ac

Reduced macular function in ABCA4 carriers.

To study retinal function and morphology in ABCA4 carriers to investigate if ABCA4 carriership is associated with any functional or morphological changes and, if so, to explore whether certain mutations may be associated with particularly severe alterations.

Geochronology of high-pressure mafic granulite dykes in SW Sweden; tracking the P-T-t path of metamorphism using Hf isotopes in zircon and baddeleyite

Although the U-Pb zircon chronometer has been widely used for dating metamorphism in moderate to high-grade rocks, it is generally difficult to link the U-Pb age of zircon to specific metamorphic reactions. In this study, the initial Hf isotopic composition of secondary zircon is compared with the evolution of Hf isotopic composition of the bulk sample, back-projected from the measured value throu
