Terminal pumping has recently been installed in the Lund tandem Pelletron electrostatic accelerator. The equipment allows a higher gas density in the stripper and an improved vacuum in the accelerator tubes compared to the former system. This improvement has led to an increased beam transmission and to superior measurements for our accelerator mass spectrometry programme. The pressure profile of t
We present a comparative analysis of the unfolding and inactivation of three cutinases in the presence of guanidine hydrochloride (GdnHCl) and bis(2-ethylhexyl) sodium sulfasuccinate (AOT). Previous investigations have focused on the cutinase from Fusarium solani pisi (FsC). In addition to FsC, the present study includes the cutinase from Humicola insolens (HiC) and a mutant variant of HiC (mu HiC
OBJECTIVES: To examine the mechanisms by which intrauterine growth restriction may influence later cardiovascular risk by comparing the ventriculovascular physiology of gestational age- and weight-matched growth-restricted and normal fetuses. DESIGN: A prospective longitudinal observational study of 20 normal fetuses studied from 20 weeks to term at monthly intervals was compared with a growth-res
Popular Abstract in Swedish Syftet med avhandlingen är att belysa hur det går till när lärare och elever görs till moraliska och etiska individer i klassrummet. Vi vill visa detta utifrån begreppet ansvar. Vi har observe-rat lektioner och intervjuat lärare och elever för att få reda på hur man talar om ansvar och hur man går tillväga för att skapa ansvariga individer. Vi har också studerat offentlThe perspective of this dissertation is grounded in the ideas and concepts of Michel Foucault. In analy-sing our empirical material we used his notions of discourse and discoursive practice, power, govern-mentality and subjectification. We were also inspired by Thomas Popkewitz, Jennifer Gore and Nicolas Rose. The aim of this dissertation is to elucidate how teachers and students are constructed a
Negotiations involving foreign aid are different from other types of bilateral negotiations. Normative and cultural aspects are distinctive attributes of aid negotiations, complicating any attempt to explain negotiation outcomes solely from a power perspective. Foreign aid negotiations between Sweden and Tanzania are permeated with norms: that rich states should give aid, that assistance should be
Woven convolutional codes with one tailbiting component code are studied and their generator matrices are given. It is shown that, if the constituent encoders are identical, a woven convolutional encoder with an outer convolutional warp and one inner tailbiting encoder (WIT) generates the same code as a woven convolutional encoder with one outer tailbiting encoder and an inner convolutional warp (
Pressurized liquid extraction (PLE) was investigated for the extraction of two endosulfan isomers and their metabolite from two real contaminated soil samples. PLE for 3 x 10 min at 100 degrees C was proven to be more exhaustive than Soxhlet extraction (SOX) in one soil sample. On the other soil sample investigated the method was found to be equally exhaustive as SOX. The use of hazardous organic
The sound values of /z/ and /r/ in proto-Nordic are discussed. It is suggested that the modern Swedish [r] and [R] are different results in different areas of the merger between /z/ and /r/ in Old Swedish, depending on the distribution of stress in polysyllabic words. The article is a shorter version of Teleman, U. (2005), Om r-fonemets historia i Svenskan (Nordlund 5). Insittutionen för nordiska
We investigate how a small polar molecule, urea, can act to protect a phospholipid bilayer system against osmotic stress. Osmotic stress can be caused by a dry environment, by freezing, or by exposure to aqueous systems with high osmotic pressure due to solutes like in saline water. A large number of organisms regularly experience osmotic stress, and it is a common response to produce small polar
The verification of the correctness of planned and executed treatments is imperative for safety in radiotherapy. The purpose of the present work is to describe and evaluate the quality assurance (QA) procedures for patient dosimetry implemented at the boron neutron capture therapy (BNCT) facility at Studsvik, Sweden. The dosimetric complexity of the mixed neutron-photon field during BNCT suggests
The Lamperti transformation of a self-similar process is a strictly stationary process. In particular, the fractional Brownian motion transforms to the second order stationary Gaussian process. This process is represented as a series of independent processes. The terms of this series are Ornstein-Uhlenbeck processes if $H<1/2$, and linear combinations of two dependent Ornstein-Uhlenbeck processes
‘The Nurse in Primary Health Care with Special Focus on Child Health Care’ The function of nurses in Swedish primary care involves health care and medical care for people of all ages, and in their health-promotion work there is a focus on child health care. Child health care in Sweden is mostly provided by nurses. The work encompasses all children from birth to school age; it is voluntary and fre
This paper suggests sufficient conditions for asymptotically stable dynamical output feedback controller design based on the circle criterion. It is shown that a dynamic output feedback stabilization problem with impending problems of finite escape time, previously attacked by observer-based design, can be successfully solved using circle criterion design. Stability of the closed-loop system is gl
To facilitate high-throughput biomarker discovery and high-density protein-chip array analyses of complex biological samples, a novel macro- and nanoporous silicon surface for protein microarrays was developed. The surface offers three-dimensional surface enlarging properties and spot confinement, enabling both high sensitivity bioassays and design of high density arrays. Reproducible manufacturin
Remains of the mosasaur Clidastespropython in marine strata of latest early Campanian age from the Kristianstad Basin, southern Sweden, represent the first record of Clidastes outside of North America. The material consists of shed marginal and pterygoid tooth-crowns, and vertebrae (including eleven associated cervicals and dorsals from a juvenile). The majority of the teeth and skeletal elements
A general mathematical model for the characterization of the dynamic (kinetically labile) association of supramolecular assemblies in solution is presented. It is an extension of the equal K (EK) model by the stringent use of linear algebra to allow for the simultaneous presence of an unlimited number of different units in the resulting assemblies. It allows for the analysis of highly complex dyna
From 1975 through 1995, 45,025 knee arthroplasties were recorded in the prospective Swedish Knee Arthroplasty study. By the end of 1995, 1,135 of 14,772 primary unicompartmental knee arthroplasties (UKA) for localized, mainly medial arthrosis had been revised. The Marmor/Richards and St. Georg sledge/Endo-Link prostheses were used in 65%. Mean age at revision was 72 (71) years. 232 revisions were
