Popular Abstract in Swedish Trumljud är det ljud som hörs i ett rum då ett objekt, till exempel en fot, träffar golvytan i samma rum. Ökande användning av tunna och hårda golvbeläggningar, såsom parkett och laminatgolv, kan leda till ljudstarka och skarpa ljud, vilket har ökat intresset av trumljud. En prediktionsmodell för den subjektiva responsen av trumljud vid en parvis jämförelse har tagits fDrum sound is the sound produced when an object, such as a foot, hits the flooring in the room in which the receiving ear is located. Drum sound has attracted interest in recent years, particularly due to an increased use of thin floating floor constructions, such as veneer or laminate flooring, which can produce loud and sharp walking sound. A prediction model of the subjective response, in a pai

Popular Abstract in Swedish Nollvisionen antagen av Sveriges riksdag fastlägger att ingen skall behöva dödas eller skadas svårt i trafiken i Sverige. Införande av detta begrepp förskjuter fokus från trafikolyckorna till konsekvenserna av trafikolyckorna och härmed skapas förutsättningar för ett paradigmskifte i trafiksäkerhetsarbetet. För att åstadkomma önskade förändringar är det nödvändigt och bThe over-arching objectives of this thesis were to formulate a method to describe the consequences of traffic casualties, and to explain the influence of different traffic engineering factors on these consequences for society and individuals over time. A more detailed objective was to examine whether available short-term indicators can be used to predict consequences in a long-term perspective. Ot

Background: Working memory is considered to influence a range of linguistic skills, i.e. vocabulary acquisition, sentence comprehension and reading. Several studies have pointed to limitations of working memory in children with specific language impairment. Few studies, however, have explored the role of working memory for language deficits in children with hearing impairment. Aims: The first aim

This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. swirl, stagnation points and anisotropic turbulence. Also, using LES one can obta

Popular Abstract in Swedish Bildundervisningen i grundskolans tidigare år uppfyller inte de i Sverige uppsatta målen. De nationella utvärderingarna (NU 89) och (NU92) bekräftar detta. Lärarna säger att de saknar ämneskunskaper och utvärderingarna visar att inslag från äldre läroplaner präglar undervisningen. För att ge en bild av hur nuvarande problem kan ha uppstått presenteras i studien en histoThe art education in Swedish primary and secondary schools is far from perfect and as a result pupils seldom reach the desired standard. National evaluations in 1989 and 1992 confirm this. Teachers admit that they lack specific subject knowledge and evaluation reveals that many aspects of older curricula still prevail. The way in which the present problems may have arisen is described through the

Atrial fibrillation is the most common cardiac arrhythmia that demands medical attention. Computer-based detailed analysis of cardiac electrical signals from healthy subjects and patients with a history of atrial fibrillation has become an important tool in the further clarification of this disease. The aim of this study was to explore supraventricular conduction using the following selected techn

Wireless communication systems are by nature and by regulations limited in bandwidth and are therefore limited in capacity. Services with Quality of Service (QoS) requirements will enforce a more efficient utilisation of the available capacity. This observation motivates the development of schedulers that can deliver the required QoS as well as being resource efficient. In this thesis, we study r

Background. An altered renal function is an essential component of the patho-physiology of pre-eclampsia. The plasma levels of low molecular mass proteins, e. g. beta-trace protein, beta-2-microglobulin and cystatin C, are increased in the third trimester of normal pregnancy. The plasma levels of cystatin C and beta-2-microglobulin are further increased in preeclampsia, and the cystatin C level ha

Popular Abstract in Swedish Yrsel är ett vanligt förekommande symtom hos patienter som besöker primärvården. Det är det vanligaste symtomet hos äldre patienter och har identifierats som en riskfaktor för fall och nedsatt funktion i innerörats balansorgan har hittats hos patienter med höftfrakturer och handledsfrakturer. Man har också påvisat att 25 % av patienterna med kvarstående besvär efter whiDizziness is a common reason for visits to primary health care, especially among elderly patients. From a physiotherapeutic perspective, this thesis aims to study the assessment and treatment of dizzy patients in primary health care. Interventions in papers I, III and IV comprised a vestibular rehabilitation programme. In paper I, patients with multisensory dizziness were randomized to interventi

Radial motions of stars in nearby moving clusters are determined fromaccurate proper motions and trigonometric parallaxes, without any use ofspectroscopy. Assuming that cluster members share the same velocityvector (apart from a random dispersion), we apply a maximum-likelihoodmethod on astrometric data from Hipparcos to compute radial and spacevelocities (and their dispersions) in the Ursa Major,

BACKGROUND: Proper treatment of lymph node-negative breast cancer depends on an accurate prognosis. To improve prognostic models for this disease, we evaluated whether an immunohistochemical marker for proliferating cells, Ki-S2 (a monoclonal antibody that binds to a 100-kd nuclear protein expressed in S, G2, and M phases of the cell cycle), is an accurate indicator of prognosis.METHODS: We studie

Object. With increasing use of endovascular procedures, the number of aneurysms treated surgically will decline. in this study the authors review complications related to the surgical treatment of aneurysms and address the issue of maintaining quality standards on a national level. Methods. A prospective, nonselected amalgamation of every aneurysm case treated in five of six neurosurgical centers

Background Subjective evaluation of gray-scale and Doppler ultrasound findings (i. e., pattern recognition) by an experienced examiner and preoperative serum levels of CA-125 can both discriminate benign from malignant adnexal ( i. e., ovarian, paraovarian, or tubal) masses. We compared the diagnostic performance of these methods in a large multicenter study. Methods In a prospective multicenter s

Bias caused by collecting and processing bulk samples is largely independent of what fossil clade or mineral is searched for. Instead, different methods bias the data to a different, frequently very large, degree. Furthermore, biases accumulate with each recovery step, and the sum may be extreme unless appropriate methods to minimize it are employed. The effects depend on what the data are used fo

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

Popular Abstract in Swedish Den här avhandlingen behandlar analys och bearbetning av bilder ur ett beräkningsmässigt perspektiv. Den är uppdelad i tre delar, vilka diskuterar bilder i så olika sammanhang som i ett artificiellt seende system för robotar, i det mänskliga seendet och i ett bildbehandlingssystem för analys av förbränningsförlopp i tex bilmotorer. Den första delen handlar om två styckThis thesis is divided into three parts, which all deal with computational analysis and processing of images. However, the settings are quite diverse.They range from robotic camera sensors, over human perception, to physical measurement setups. In spite of this diversity, common theoretical ideas and computational aspects are applied which ties the three different parts closer together. The first

Based on a literature review and the SSG experience, the most important prognostic factors in high-grade osteosarcoma appear to be the presence of detectable metastases at diagnosis, tumour volume, old age, sex, histologic response, and possibly tumoral P-glycoprotein expression. However, for an adolescent patient with non-metastatic extremity disease, there is no consensus regarding prognostic fa

Objectives. Natural colloid albumin induces a lesser degree of dilutional coagulopathy than synthetic colloids. Fibrinogen concentrate has emerged as a promising strategy to treat coagulopathy, and factor XIII (FXIII) works synergistically with fibrinogen to correct coagulopathy following haemodilution with crystalloids. Our objectives were to examine the ability of fibrinogen and FXIII concentrat

The aim was to explore the utility for staging and prognostic impact of carcinoembryonic antigen (CEA), cytokeratin 20 (CK20), guanylyl cyclase C (GCC), CUB (complement protein subcomponents C1r/C1s, urchin embryonic growth factor, and bone morphogenic protein 1) containing domain protein 1 (CDCP1) and mucin 2 (MUC2) mRNA levels in mesenteric lymph nodes of colorectal cancer (CRC) patients.
