The T matrix for scattering of waves by a circular disk is derived. Both the scalar (Dirichlet and Neumann boundary conditions) and the vector (perfectly conducting disk) cases are considered and the use of alternative choices for surface field functions is discussed in detail, and it is found that either type of the surface field representation is equally good for the disk case. Analytic expressi

ABSTRACT: Study Design. Epidemiological total population study based on a prospective follow-up CP registry.Objective. To describe the prevalence of scoliosis in a total population of children with CP, to analyse the relation between scoliosis, gross motor function and CP subtype, and to describe the age at diagnosis of scoliosis.Summary of Background Data. Children with cerebral palsy (CP) have a

The purpose of the present paper is to outline emerging trends in nanomedicine, as well as to discuss some of the potential benefits and problems the medical applications of nanotechnologies may give rise to. In the paper some of the suggestions recently made by the European Group on Ethics in Science and New Technologies concerning how to deal with some of these problems are presented. I conclude

This thesis consists of four essays discussing network structures and institutions in financial markets. The first essay explores the determinants of the egocentric lending networks of stock listed companies in China. Egocentric lending networks are constructed using the public loan announcements of firms listed on China’s two stock exchanges combined with cross-ownership shares connecting the len

Abstract Objectives. To compare identical versus compatible, ABO blood group matching effects on rejection and long-term survival after heart transplantation (HT). Design. Data were collected from 196 patients who underwent HT at Lund University Hospital between 1988 and 2008. Cox proportion hazard regression analysis was used to identify factors associated with reduced long-term survival. Results

Time resolved laser spectroscopy in the VUV spectral region is applied to investigate the (n=5-8) 3d(10) 4snp P-1(1) series of neutral zinc. The natural lifetimes of this series were measured by time-resolved laser-induced fluorescence. We find tau(n=5)=11.7(9) ns, tau(n=6)=80(8) ns, tau(n=7)=179(20) ns and tau(n=8)=356 (35) ns. These results are compared with a theoretical calculation.

We present a systematic study of the angular distributions of high-order harmonics generated with a femtosecond Cr:LiSrAlF6 laser. We investigate the influence of different parameters, namely laser intensity, nonlinear order, nature of the gas and position of the laser focus relative to the generating medium. We show that when the laser is focused before the atomic medium, harmonics with regular s

BACKGROUND: Cannabinoid (CB) receptors may be involved in the control of bladder function; the role of CB receptor subtypes in micturition has not been established. OBJECTIVES: Our aim was to evaluate the effects of cannabinor, a novel CB2 receptor agonist, on rat bladder function. DESIGN, SETTING, AND PARTICIPANTS: Sprague Dawley rats were used. Distribution of CB2 receptors in sensory and cholin

BACKGROUND: Subclinical myocardial injury has been reported in newborns with fetal weights < 2 SDs for gestational age. Intrauterine growth restriction might affect cardiac function and coronary flow (CF). METHODS: Seventeen newborns with intrauterine growth restriction and 15 age-matched healthy controls were enrolled in the study. Blood flow in the umbilical artery and maternal uterine artery wa

This article presents a reading of two Greek Marian hymns written in the centuries after the Ephesus Council: the Annunciation Hymn by Romanos the Melodist, which is the earliest extant Annunciation hymn we have, and the well-known Akathistos Hymn. Many scholars believe the latter to be a fifth century composition, and not – as have been claimed by such important scholars as Constantinos A. Trypan

Popular Abstract in English Nowadays, the majority of energy production comes from combustion which is universally linked to daily human activities. Public awakening of the environmental effects of combustion pollution evokes extensive research activities in improving combustion efficiency and reducing pollutant production. Development of combustion processes also includes the use of renewable bioThe work presented in the thesis concerns the developments of laser-based diagnostics and its application to the study of turbulent premixed combustion. The diagnostic developments, mainly concerned with planar laser-induced fluorescence (PLIF), are intended to provide instantaneous visualization of the key species originating from the combustion processes involved in the burning of hydrocarbons

This study analyzed vowel productions of Swedish children with cochlear implants, capitalizing on the rich vowel system of Swedish with nine vowels. Minimal word pairs were used as linguistic material. A group of 12 children with CI (mean age 184 months, range 144-229 months), and a group of children with normal hearing (mean age 105 months, range 103-118 months) were recruited. The age at implant
