The relationship between the relative humidity and the moisture content of a material for relative humidity levels close to 100% can be studied using the pressure plate technique. However, this method is designed for desorption experiments and modifications are necessary in order to perform absorption experiments. This paper presents a method to condition samples to a uniform moisture content by a
Svensson F, Fredlund C, Svedin CG, Priebe G, Wadsby M. Adolescents selling sex: Exposure to abuse, mental health, self-harm behaviour and the need for help and support-a study of a Swedish national sample. Nord J Psychiatry 2013; 67: 81-88. Background: Selling sex is not uncommon among adolescents and we need to increase our knowledge of how this affects them. Aim: The aim of this study was to inv
The first appearance datum (FAD) of the cosmopolitan agnostoid trilobite Lotagnostus americanus is a widely used marker for defining the base of the uppermost stage of the Cambrian System. Detailed field study on the L. americanus-bearing interval of the Wa'ergang section, Hunan, China, reveals the FAD of L. americanus to be 29.65m above the base of the Shengjiawan Formation. This horizon is close
Tailored supercritical carbon dioxide (scCO(2)) extraction of alkyhesorcinols (ARs) from rye bran resulting in pre-purification of ARs already during extraction process. The pre-purification was achieved by splitting the extraction process in 2 steps.. In both steps, the CO2 pressure was set at 25 MPa with a flow rate of 10 g/min. The first step was carried out at 70 degrees C. 0.06% of ethanolic
Our aim in this study was to explore women's responses to reported ad-hoc demands for unauthorized user fees during pregnancy and childbirth in Luanda, Angola. Ten focus group discussions were conducted and data were analysed using grounded theory. Women were found to apply six strategies as they "endeavored to cope with demands for unauthorized user fees" (core category): (i) blowing the whistle,
Scatter and septal penetration deteriorate contrast and quantitative accuracy in single photon emission computed tomography ( SPECT). In this study four different correction techniques for scatter and septal penetration are evaluated for I-123 brain SPECT. One of the methods is a form of model-based compensation which uses the effective source scatter estimation ( ESSE) for modelling scatter, and
Background: The study was designed to determine whether a 1-year hospital-based secondary prevention programme would have any long-term effects on serum lipid levels and the use of lipid-lowering drugs in patients with coronary artery disease 4 years after referral to primary care facilities for follow-up. Design/methods: After acute myocardial infarction or coronary bypass surgery, 241 consecuti
The FRR (Friendly Rest Room) project creates and evaluates prototypes of a more user friendly intelligent toilet for old persons and for persons with disabilities. Additionally, applicable knowledge regarding needs and wishes of old and/or disabled persons and their care persons are documented. In this paper the user driven research approach, ethical aspects and the iterative user centred design p
Popular Abstract in Swedish Ett varmare klimat ökar generellt risken för angrepp av skadeinsekter på jordbruksgrödor, och många skadeinsekter förväntas sprida sig norrut. Den här avhandlingen fokuserar på hur ett varmare klimat kan påverka koloradoskalbaggen, en allvarlig skadegörare i potatisodlingar. Koloradoskalbaggen kom från Mexiko till Europa i början av 1900-talet, och har sedan dess spridiEuropean agriculture is facing the challenge of managing the impact of climate change on food security. Agriculture in a northern temperate climate is likely to benefit from higher temperature and longer growing season while, in the south, crop productivity is likely to decline. Such changes in climate could also affect the population dynamics of insect pests. The Colorado potato beetle (CPB) is o
Popular Abstract in Swedish Oberoende av om det är i ett samhälle, datornätverk eller organen i en mänsklig kropp, så är behovet av kommunikation stort i en komplex miljö. Eftersom den komplicerade människokroppen är beroende av kommunikation för att reglera funktioner, skickas otaliga mängder signaler oavbrutet. För att signalerna skall vara meningsfulla så måste de kunna tas emot och behandlas. Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. Since an estimated 50% of all clinical drugs act on 30 known GPCRs, the rem
Objective: Catheter-associated urinary tract infection (CAUTI) is the most common healthcare-associated infection. The primary aim of this study was to investigate whether the use of a silicone catheter coated with an ultrathin layer of a combination of the noble metals gold, palladium and silver (BIP™–silicone catheter) could reduce the incidence of CAUTI and antibiotic prescription compared with
We have developed over the past years an experimental magnetic resonance imaging (MRI) and polarized gases compatible mechanical respirator for the study of the small experimental animal. The respirator has been successfully used for experiments both in the MRI setting for polarized (3)He, (19)F, and proton imaging as well as for functional measurements of the lungs. The new main pneumatic valve w
Monitoring and control of proper Key Performance Indicators of plant performance have high correlation with business performance. So it is very important at plant-wide level to ensure that process control developments are being developed aligned with business strategy as Advanced Process Control projects have as ultimate goal to help achieving gains in this direction. The ISO 22400 “Key Performanc
This thesis analyses the operations of the principle of proportionality when the Court of Justice reviews national measures that restrict the fundamental freedoms laid down in the EU Treaties. That judicial review often entails balancing of rights, and this study is a quest for coherence in the adjudication of different, and at times perplexing legal norms, of various national and international or
BACKGROUND: Maternal prepregnancy obesity (BMI ≥30 kg/m(2)) and excessive gestational weight gain (GWG) have shown a strong positive association with a higher BMI and risk of obesity in the offspring. The aim of this study is to estimate the effect of a GWG restriction program for obese pregnant women on the children's BMI at 5 years of age and weight-for-length/height (WL/H) development from 2 mo
Objective: To evaluate the performance characteristics of direct and capture ELISA for the detection of PR3-ANCA in Wegener's granulomatosis (WG) in international ANCA reference laboratories. Methods: Serum samples were derived from patients with histological and clinical diagnosis of WG (n = 60), rheumatoid arthritis (RA) (n = 30) and healthy controls (n = 30). Each of them was tested for the pre
