Since Varian (Econometrica 50:945–973, 1982; Review of Economic Studies 50:90–110, 1983) made checking for consistency with revealed preference conditions more accessible to empirical researchers; researchers have often used revealed preference procedures to test their maintained hypotheses and narrow the scope of their demand studies. The tests developed by Varian are for the direct utility funct

The REVEALS model was developed to reconstruct quantitatively regional vegetation abundance (in a 10(4)-10(5) km(2) area) from pollen assemblages in large lakes (>= 100-500 ha). This model corrects for biases in pollen percentages caused by inter-taxonomic differences in pollen productivity and dispersal. This paper presents the first case study to validate REVEALS, using empirical data from south

Communicative abilities and opportunities are affected by ventilator care. The purpose of this case study was to investigate both a nurse's and a ventilator-supported patient's experiences of communication during ventilator care, with the overall aim of contributing to increased knowledge and awareness of issues related to communication with a ventilator-supported patient. An explorative/descripti

Urinary cadmium (U-Cd) sampling can be done either by 24-h urine or spot urine sampling, and adjustment for dilution is usually needed. The choice of sampling period and adjustment technique could, however, potentially induce bias. The aim of the study was to compare 24-h urine and spot urine sampling and two dilution adjustment techniques, when assessing U-Cd. Separate 24-h urine (U24) and timed

Objectives. A family history of prostate cancer is associated with a higher risk for prostate cancer to first-degree relatives. If greater surveillance of men at familial risk is considered to be useful, population-based estimates of the differences in the age at diagnosis between familial and sporadic prostate cancer cases are needed. Methods. The men in the nationwide Swedish Family-Cancer Datab

The effects of dryer fabric cooling were studied. Using a dryer fabric cooled to a temperature below the dew point of the air-vapour mixture resulted in condensation of water vapour in the fabric structure. This condensation process was studied by means of a small-scale dynamic pilot dryer. The novel model on mass and heat transport in dryer fabrics, described in part 1, was validated against expe

Background and purpose - Treatment of Dupuytren's contracture (DC) with collagenase Clostridium histolyticum (CCH) consists of injection followed by finger manipulation. We used a modified method, injecting a higher dose than recommended on the label into several parts of the cord, which allows treatment of multiple joint contractures in 1 session and may increase efficacy. We studied the occurren

The dimeric metabolic enzyme phosphoglucose isomerase (PGI, EC 5.3.1.9) plays an essential role in energy production. In the grass Festuca ovina, field surveys of enzyme variation suggest that genetic variation at cytosolic PGI (PGIC) may be adaptively important. In the present study, we investigated the molecular basis of the potential adaptive significance of PGIC in F. ovina by analyzing cDNA s

The transparency regulator hypothesis (TRH) proposes that ultraviolet radiation (UVR) is a main driving force behind diel vertical migration (DVM) of zooplankton in clearwater systems. While previous studies have mainly studied DVM in relation to the TRH on a spatial scale across systems we here focus on long-term trends in a single system in order to assess if UVR explains observed patterns in DV

Familial clustering of chronic obstructive pulmonary disease (COPD) is well established, but the familial risk of COPD has not been determined among adoptees. The aim was to determine whether the familial transmission of COPD is related to disease in biological and/or adoptive parents.

OBJECTIVE. Screening examination for retinopathy of prematurity is distressing and painful. The aim of the present study was to investigate whether a Newborn Individualized Developmental Care and Assessment Program intervention during a retinopathy of prematurity examination results in less adverse behavioral, pain, and stress responses as compared with standard care. METHODS. The first 2 eye exam

Popular Abstract in Swedish Oönskade reaktioner efter vaccination och allergenspecifik immunoterapi - Kontaktallergi för aluminium och kliande knutor För att ett vaccinationsprogram ska fungera krävs kontinuerlig uppföljning av vaccinernas säkerhet vad gäller eventuella oönskade reaktioner. Under de senaste 10 till 15 åren har en ökad oro noterats bland allmänhet och profession beträffande oönskadThe aim of the work presented in this thesis was to investigate two different types of adverse reactions, persistent itching nodules and contact allergy to aluminium, after immunization with aluminium-containing vaccines and aluminium-containing allergen extracts used for allergen-specific immunotherapy (ASIT). The first paper describes active parental reporting of adverse events (AEFIs) after a

The standard pharmacological treatment for Parkinson's disease using the dopamine precursor levodopa is unfortunately limited by gradual development of disabling involuntary movements for which the underlying causes are poorly understood. Here we show that levodopa-induced dyskinesia in hemiparkinsonian rats is strongly associated with pronounced 80 Hz local field potential oscillations in the pri

Objective To investigate if the prediction of malignant adnexal masses can be improved by considering different ultrasound-based subgroups of tumors and constructing a scoring system for each subgroup instead of using a risk estimation model applicable to all tumors. Methods We used a multicenter database of 1573 patients with at least one persistent adnexal mass. The masses were categorized into

Sixty-four Polish families with a history of breast and/or ovarian cancer were screened for mutations in the BRCA1/2 genes using a combination of denaturing high performance liquid chromatography (DHPLC) and sequencing. Two thirds (43/64; 67%) of the families were found to carry deleterious mutations, of which the most frequent were BRCA1 5382insC (n=22/43; 51%) and Cys61Gly (n=9/43; 20%). Two oth

The opportunistic human pathogen Pseudomonas aeruginosa causes a wide range of diseases. To cross host innate immune barriers, P. aeruginosa has developed efficient strategies to escape host complement attack. In this study, we identify the 57-kDa dihydrolipoamide dehydrogenase (Lpd) as a surface-exposed protein of P. aeruginosa that binds the four human plasma proteins, Factor H, Factor H-like pr

2012 är året då tsunamin drabbade högre utbildning. Den öppna utbildningskulturen slår igenom på bred front i hela världen, bland annat genom att prestigeuniversitet, inte minst i USA, erbjuder kurser gratis online och globalt till alla. Men i Sverige är öppen utbildning ännu i hög grad en icke-fråga, speciellt bland myndigheter och utbildningsorganisationer.
