Bat flight generates complex aerodynamic tracks

The flapping flight of animals generates an aerodynamic footprint as a time-varying vortex wake in which the rate of momentum change represents the aerodynamic force. We showed that the wakes of a small bat species differ from those of birds in some important respects. In our bats, each wing generated its own vortex loop. Also, at moderate and high flight speeds, the circulation on the outer ( han

Creep Recovery and Elastic Modulus of High Performance Concrete

This article outlines an experimental and numerical study on short-term and long-term creep recovery in High Performance Concrete. About 200 cylinders and 800 cubes were tested. The ambient climate was held constant at 20 °C and 55% relative humidity. Results and analyses are presented as regards short-term and long-term creep recovery with some related properties. The creep deformations are separ

Increased incidence of cardiovascular disease in patients with rheumatoid arthritis: results from a community based study

Objective: To investigate the first-ever incidence of acute myocardial infarction and stroke in a community based RA cohort compared with the general population. Methods: The RA cohort consisted of all patients in a local RA register in Malmo, Sweden (n = 1022). The patients were recruited from private and hospital based rheumatology practices, and made up the absolute majority of patients with RA

Sagali and the Kula : A Regional Systems Analysis of the Massim

This thesis is concerned with developing a consistent regional perspective on the Massim peoples of southeastern Papua New Guinea, a task largely neglected by earlier anthropological studies, it is claimed, or, when sometimes attempted, unsuccessfully accomplished for a number of reasons, both methodological and theoretical. The author uses a comparative approach for investigating a selection of

Skoldaghem: Ett alternativ för elever i behov av särskilt stöd

Popular Abstract in Swedish Studien handlar om tio elever i behov av särskilt stöd. Den förhärskande tanken inom det svenska utbildningsväsendet är att elever med funktionshinder ska integreras i den vanliga skolan. Undantag får emellertid göras och eleverna kan t.ex. få sin skolgång på ett skoldaghem. Det främsta syftet med föreliggande studie är att undersöka hur sju elever med skolgång på skolThis thesis concerns ten pupils in need of special support. The overriding principle governing the Swedish educational system today is that pupils with functional difficulties should be integrated into ordinary schools, but exceptions may be made and the pupils can attend a special day-school. The primary aim of the present thesis is to study the progress of seven students, attending special day-s

UAMSHO: A Theological Study of the Proclamation of the Revival Movement within the Evangelical Lutheran Church in Tanzania

This thesis presents a theological study of the revival (Uamsho) movement within the Evangelical Lutheran Church in Tanzania (ELCT). This movement is part of the East African Revival Movement that began during the late 1920's within the Protestant churches in Rwanda, after which it spread to Uganda, Kenya, and Tanzania. The introductory chapter begins with a presentation of characteristic feature

Peptide folding and aggregation studied using a simplified atomic model

Using an atomic model with a simplified-sequence-based potential, the folding properties of several different peptides are studied. Both alpha-helical (Trp cage, F-s) and beta-sheet(GB1p, GB1m2, GB1m3, Betanova, LLM) peptides are considered. The model is able to fold these different peptides for one and the same choice of;parameters, and the melting behaviour of the peptides (folded population aga

Abdominal adhesions - clinical impact and experimental prevention

Popular Abstract in Swedish Sammanväxningar i buken är en normal reaktion efter skador i bukhinnan och utvecklas efter ett inflammatoriskt svar och det efterföljande läkningsförloppet. Många sammanväxningar bildas inom 24-48 timmar efter skadan och tillbakabildas normalt efter 5-7 dagar. Många av de sammanväxningar som kvarstår kan ses som en obalans i de system som bildar ärr (fibros) och löser dIntraabdominal adhesions are formed after most operations and a limited number of studies have to examine the long-term spectrum of adhesion-related disorders and the cost associated with this. Only a few numbers of antiadhesive agents are available which, however, do not decrease the actual morbidity that follows intraabdominal adhesions, such as small bowel obstruction, infertility and pain. Fut

Dynamic reasoning to solve complex problems in activated sludge processes: a step further in decision support systems

Decision support systems (DSS) have generated high expectations as a tool to support activated sludge operation because of their ability to represent heuristic reasoning and to handle large amounts of qualitative, uncertain and low-accuracy data. Previous applications have been satisfactory to control simple problems, when static reasoning and literature-based solutions were enough. However to fac

DNA based classification of food associated Enterobacteriaceae previously identified by biolog GN microplates

Enterobacteriaceae are frequently isolated from food products and it is essential to have methods for correct identification for both food hygiene and epidemiology reasons. Phenotypic methods are not always sufficient and have to be supplemented by DNA based methods. In the present study, 70 strains of Enterobacteriaceae derived from milk, fish and meat that had previously been identified by Biolo

Experimenthus med väggar av träullsblock

Dålig inomhusmiljö är ett problem i dagens bostäder. orsakerna är flera, bl a introducerandet av nya obeprövade material, olämpliga konstruktioner som medför fuktproblem samt dålig luftomsättning kombinerat med hög täthet. I Staffanstorp utanför Lund uppfördes under 1996 ett experimenthus som formgivits av arkitekt Karin Grundström. Målsättningen var att åstadkomma en sund och estetiskt tilltaland

Enantioseparation of D- and L-amino acids by a coupled system consisting of an ion-exchange column and a chiral column and determination of D-aspartic acid and D-glutamic acid in soy products

A coupled system, consisting of a conventional ion-exchange column and a chiral column, was used for separation of the D- and L-enantiomers as constituents of an amino acid mixture. The ion-exchange column was connected to an amino acid analyser and the eluents necessary for the chiral column were delivered by an HPLC pump. With this on-line system the D- and L-forms of eight of the proteinogenic
