Fast and sensitive time-multiplexed gas sensing of multiple lines using a miniature telecom diode laser between 1529 nm and 1565 nm

High-sensitive multi-species detection around 1550 nm using a modulated grating Y-branch, MG-Y, diode laser tunable between 1529 nm and 1565 nm is presented. The MG-Y diode laser is based on the Vernier effect of two modulated gratings, and exhibits quasi-continuous tuning over 36 nm. Multi-species detection is achieved by fast sequential scanning of single absorption lines of CH4, CO, C2H2, and C

Enhanced levels of immunoreactive beta-casomorphin-8 in milk of breastfeeding women with mastitis

An incorrect, superficial suckling technique in breastfeeding frequently leads to milk congestion and sometimes mastitis. In the present study we have examined whether milk congestion may affect levels of the atypical opioid beta-casomorphin-8 in milk and in plasma. We also investigated whether the rate of acute psychosis during the first half year after parturition has declined in Sweden over the

A comparison between nailfold capillaroscopy patterns in adulthood in juvenile and adult-onset systemic sclerosis: A EUSTAR exploratory study

Objective: Qualitative capillaroscopy patterns in juvenile- and adult-onset systemic sclerosis (SSc) were studied in adulthood using data from the EULAR Scleroderma Trials and Research (EUSTAR) database. Methods: Data collected between June 2004 and April 2013 were examined with focus on capillaroscopy. In this retrospective exploratory study, series of patients with juvenile-onset SSc were matche

Allogeneic haematopoietic stem-cell transplantation with reduced intensity conditioning for advanced stage Hodgkin's lymphoma in Sweden: high incidence of post transplant lymphoproliferative disorder

Allogeneic transplantation after reduced intensity conditioning (allo-RIC) is a treatment option for patients with Hodgkin's lymphoma (HL) relapsing after autologous transplantation. In all, 23 adult patients with HL underwent allo-RIC in Sweden between 2000 and 2007. The median number of previous treatment lines was five and 20 patients (87%) were previously autografted. TRM at 100 days and at 1

Comparators, study duration, outcome measures and sponsorship in therapeutic trials of psoriasis: update of the EDEN Psoriasis Survey 2001-2006

Background Several new therapeutic options for psoriasis have been tested in clinical trials in recent years. Choice of comparator, study duration and outcome measures are critical for interpreting application of trial results to clinical practice. Objectives We examined whether these trial aspects have changed substantially in recent years in comparison with the past. Methods A systematic search

High Survivin Levels Predict Poor Clinical Response to Infliximab Treatment in Patients with Rheumatoid Arthritis

Objective: To evaluate if the measurement of survivin in the blood of patients with rheumatoid arthritis (RA) undergoing infliximab treatment has predictive value for treatment response. Methods: The study included 87 consecutive RA patients (age 24-89 years, disease duration 18-526 months) treated with regular infusions of influximab. Survivin levels were measured by enzyme-linked immunosorbent a

Long- term change of daily and multi- daily precipitation in southern Sweden

Daily rain series from southern Sweden with records dating back to the 1870s have been analysed to investigate the trends of daily and multi-day precipitation of different return periods with emphasis on the extremes. Probabilities of extreme storms were determined as continuously changing values based on 25 years of data. An extra set of data was used to investigate changes in Skane, the southern

Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. Pesticides and various industrial chemicals such as dioxin and PCBs are also EDCs that often find th

Verification and validation in industry - a qualitative survey on the state of practice

Verification and validation activities take a substantial share of project budgets and need improvements. This is an accepted truth, but the current practices are seldom assessed and analyzed. In this paper we present a qualitative survey of the verification and validation processes at 11 Swedish companies. The purpose was to exchange experience between the companies and to lay out a foundation fo

Growth versus the Environment - Is There a Trade-off?

This book shows that the intensity of use of energy and materials in OECD countries is diminishing over time despite falling metal and energy prices. Material demand is sometimes falling in absolute terms, but there are also a few examples of rapid growth. The supply of fossil fuels and minerals is being exhausted, in some cases at a rapid speed, but the question addressed here is whether the rat

Lactobacillus in semi-hard cheese and their use as adjunct cultures

The microflora of Herrgård cheese produced at three dairies was compared after three and six months maturation. The microflora of cheeses from two of the dairies was dominated by a spontaneous microflora of Lactobacillus after three months of ripening, while starter bacteria still dominated in cheese from the third dairy after six months. Isolates were typed by the PCR-based method Randomly

En jämförelse av hälsoeffekter vid kort daglig träning i medveten närvaro och tillämpad avslappning: En randomiserad och replikerad studie

Denna randomiserade och replikerade studies syfte var att undersöka hälsoeffekter av 15 minuters daglig träning i medveten närvaro och tillämpad avslappning. Hälsoeffekterna mättes med skalor som skattar medveten närvaro, ohälsa, positiva och negativa affekter, livstillfredsställelse och välbefinnande. Undersökningen utfördes under 30 dagar med 234 deltagare i tre randomiserade grupper. Utan teoreThe purpose of this randomized and replicated study was to investigate the health effects of 15 minutes of daily training in mindfulness or applied relaxation. The health effects were measured by scales that assess mindfulness, health, positive and negative affects, life satisfaction and psychological wellbeing. The training period was 30 days and 234 persons participated in three randomly assigne

Semivarians, ett användbart riskmått eller endast ett överflöd?

Since Markowitz presented the mean-variance model as a way of putting together a financial portfolio, variance has been the established measure of risk. Even though the measures of downside risk hasn’t gained the same attention as variance, it has been used in research for some time. Semivariance, best described as the risk of a portfolio’s return falling below a set target, was introduced as a ri

Decreased monoamine metabolites in frontotemporal dementia and Alzheimer's disease

The concentrations of the monoamine metabolites homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol (HMPG) in the cerebrospinal fluid (CSF) of patients with clinical frontotemporal dementia (FTD; n = 30), early onset Alzheimer's disease (EAD; n = 33), late onset Alzheimer's disease (LAD, n = 27) and normal controls (n = 31) were determined using HPLC. A

Daily physical activity and its relation to aerobic fitness in children aged 8-11 years.

A positive relationship between daily physical activity and aerobic fitness exists in adults. Studies in children have given conflicting results, possibly because of differences in methods used to assess daily physical activity and fitness. No study regarding daily physical activity and fitness in children has been published, where fitness has been assessed by direct measurement of maximum oxygen

Space weather events in July 1982 and October 2003 and the effects of geomagnetically induced currents on Swedish technical systems

In this paper, we analyse in detail two famous space weather events; a railway problem on 13-14 July 1982 and a power blackout on 30 October 2003. Both occurred in Sweden during very intensive space weather storms and each of them a few years after the sunspot maximum. This paper provides a description of the conditions on the Sun and in the solar wind leading to the two GIC events on the ground.

Application of supercritical carbon dioxide(scCO(2)) for the extraction of glycolipids from Lactobacillus plantarum B-01

Process parameters for the extraction of glycolipids by scCO(2) from Lactobacillus plantarum B-01 were optimized by carrying out a two-level fractional design experiment. The highest glycolipids extract yield was obtained at 250 bar, 40 degrees C, CO2 flow rate, 10 g/min and hydrometanolic co-solvent, 9.3% (v/v). In the lipid extracts the carbohydrate moiety of glycolipids and in phospholipids pho

Leaking roofs in Tunisia

Summary The leaking of water through roofs is a major problem in many parts of Tunisia. As a part of a collaboration between "École N: ionale d'Ingénieurs de Tunis" (E.N.I.T.) and Lund University, Institute of Science and Technology (L.N.T.H.), Sweden, a measuring method has been developed to compare the watertightness of different roofing membranes. With the method, three roof structues with diff
