The solvent extraction of phosphoric, hydrochloric, sulphuric, hydrofluosilicic and hydrofluoric acids with long-chain aliphatic amins is modelled. Pure acid equilibria are based on existing isotherms or calculated extraction constants when only experimental data are available. For binary mixtures binary combinations of acid complexes are added. In the aqueous phase Bromley's model for electrolyte
The article is an auto-ethnographical account of the practice law in the mundane everyday life at Lund District Court, Sweden. The focus is on the spatial and organizational every day conditions of practicing law in the office space. It researches the practice of law, in the office part of the court, as a human practice in a constant call between de-contamination from personal identity and a re-ca
The aim of this study was to assess possible early determinants of idiopathic environmental intolerance (IEI), contributing to an integrated model for the development of IEI. Questionnaires concerning personality traits, current mental distress, subjective health complaints, work load and satisfaction, and options for recovery, were given to 84 persons from the general population attributing annoy
Popular Abstract in Swedish Avhandlingen omfattar fyra artiklar inom empirisk finansiell ekonomi. Det första kapitlet är en kort sammanfattning av avhandlingens innehåll. Det andra kapitlet, Dynamic Portfolio Selection: The Relevance of Switching Regimes and Investment Horizon. (samförfattad med Birger Nilsson) undersöker dynamiskt portföljval och efterfrågan på tidsdiversifiering då aktieavkastnThis thesis consists of four empirical studies on financial economics. The first chapter contains a short summary of the thesis. The second chapter Dynamic Portfolio Selection: The Relevance of Switching Regimes and Investment Horizon (co-authored with Birger Nilsson) investigates the questions of dynamic portfolio selection and intertemporal hedging within a Markovian regime-switching framework.
We have monitored the composition of supported phospholipid bilayers during phospholipase A(2) hydrolysis using specular neutron reflection and ellipsometry. Porcine pancreatic PLA(2) shows along lag phase of several hours during which the enzyme binds to the bilayer surface, but only 5 +/- 3% of the lipids react before the onset of rapid hydrolysis. The amount of PLA(2), which resides in a 21 +/-
It is demonstrated that photographic images of plants can be produced in the absence of external illumination using an image intensifier. The image is produced by the weak delayed light emission (afterglow) from photosynthetically active chloroplasts. The use of such phytoluminographs is proposed for the study and diagnosis at an early stage of disturbances due to parasites, mineral deficiency, he
PHENIX has measured the centrality dependence of midrapidity pion, kaon, and proton transverse momentum distributions in d+Au and p+p collisions at root s(NN) = 200 GeV. The p+p data provide a reference for nuclear effects in d+Au and previously measured Au+Au collisions. Hadron production is enhanced in d+Au, relative to independent nucleon-nucleon scattering, as was observed in lower energy coll
Activation of AMP-activated protein kinase (AMPK) by exercise and metformin is beneficial for the treatment of type 2 diabetes. We recently found that, in cultured cells, the LKB1 tumor suppressor protein kinase activates AMPK in response to the metformin analog phenformin and the AMP mimetic drug 5-aminoimidazole-4-carboxamide-1-beta-D-ribofuranoside (AICAR). We have also reported that LKB1 activ
Mouse models of asthma are now being used extensively in drug research. However, the successful unravelling of combinatorial interplays of cells and molecules in the murine airways may not be matched by equally successful demonstrations of an asthma-like pathophysiology. Here, Carl Persson, Jonas Erjefalt, Magnus Korsgren and Frank Sundler discuss the fact that major features of asthma may still n
We show that the distance densities that can arise from a many-body wavefunction (i.e., are N-representable) lie in a convex set. We show that the N-representable distance densities have positive Fourier transforms.
Abstract The aim of this study was to evaluate a general school-based 1-year exercise intervention program in a population-based cohort of girls at Tanner stage I. Fifty-three girls aged 7–9 years were included. The school curriculum-based exercise intervention program included 40 minutes/school day. Fifty healthy age-matched girls assigned to the general school curriculum of 60 minutes physical a
OBJECTIVE: To analyse the outcome of selective management of patients with abdominal aortic aneurysms, the expansion patterns of the aneurysms, and the factors that influenced the rate of rupture. DESIGN: Retrospective study. SETTING: Malmo General Hospital, Lund University, Malmo, Sweden. SUBJECTS: 155 patients (96 men and 59 women) with abdominal aortic aneurysms who were not selected for operat
We report the isolation and partial genetic characterization of two equine strains of granulocytic Ehrlichia of the genogroup Ehrlichia phagocytophila. Frozen whole-blood samples from two Swedish horses with laboratory-verified granulocytic ehrlichiosis were inoculated into HL-60 cell cultures. Granulocytic Ehrlichia was isolated and propagated from both horses. DNA extracts from the respective st
The objectives of this study were to report our experience with the laparoscopic video-assisted gastrostomy technique in infants operated during their first year of life. A total of 53 infants (35 males, 18 females) aged 6 +/- 3 months, varying from 3 weeks to 11 months, underwent video-assisted gastrostomy. They were prospectively followed up. Included are infants with neurological dysfunction, c
AIM: Non-participation in health surveys is a common phenomenon. When differences between participants and non-participants are considerable, the external validity of the sample survey may decrease and false conclusions might be drawn about the health status of the population. For this reason, the authors aimed to investigate the representativity of a postal questionnaire survey performed in the c
