Multicentre patch test studies (MPTSs) can contribute useful information for diagnostic and preventive measures. The aim of the present paper is to propose how to perform high-quality MPTSs. To this end, factors of significance for the patch test result are discussed with regard to the standardization and calibration of high-quality MPTSs. The 16 factors discussed are scored 0, 1, 2, or 3, dependi
The Mendelian Society in Lund was founded in 1910. The initiative came from two young biologists supported by a wide circle of interested plant breeders and academics. Already from the start the society was dominated by the towering personality Herman Nilsson-Ehle. After two active years, the Society went into temporal hibernation until it resumed its activities in spring 1916, when Nilsson-Ehle w
Popular Abstract in Swedish Potatis har varit, och är fortfarande ett viktigt baslivsmedel i svensk kosthållning. Det finns många sorter med olika egenskaper vilket bidrar till dess variationsrikedom. Potatisen är en rik källa till stärkelse, kostfibrer samt vitaminer och mineraler, t ex C-vitamin och järn. En invändning mot potatis ur nutritionell synvinkel är att stärkelsen lätt bryts ned av enzDespite decreased consumption potatoes still constitute an important staple in the Swedish diet. An objection to potatoes and potato products from a nutritional point of view is the ease by which the starch is digested and absorbed in the gastrointestinal tract. This results in unfavourably high glycaemic and insulinaemic responses (glycaemic index, GI and insulinaemic index, II, respectively). Su
30 patients with malignant pleuritis were randomised to be treated, either with intrapleural instillation of mepacrine chloride or with mitoxantrone. The patients were evaluated with chest X-ray and a symptom questionnaire during a follow-up period of 12 weeks. Mitoxantrone levels in the pleural space and plasma were measured at different time points in some of the patients. High concentrations of
A rapid screening procedure for characterization of lipase selectivities using microwaves was developed. The rate of reaction of various commercial lipases (porcine pancreas, Mucor miehei, Candida rugosa, Pseudomonas cepacia) as well as lipases from laboratory isolates-Bacillus stearothermophilus and Burkholderia cepacia RGP-10 for triolein hydrolysis was 7- to 12-fold higher in a microwave oven a
Water and salt mass balances for the Dead Sea were modeled to consider different possible methods for maintaining its water level and water volume. In the models, precipitation, evaporation, rivers, ground water, input/output from potash companies and salt production, and brine discharge were included. The mixing time in the Dead Sea was modeled by a 1) single-layer (well-mixed) system, and a 2) t
In the world of cryptography, stream ciphers are known as primitives used to ensure privacy over a communication channel. One common way to build a stream cipher is to use a keystream generator to produce a pseudo-random sequence of symbols. In such algorithms, the ciphertext is the sum of the keystream and the plaintext, resembling the one-time pad principal. Although the idea behind stream ciphe
Biogas produced by anaerobic digestion is often used in gas turbines to produceelectricity. In order to increase the value of the gas and to enable utilization of the gas in other applications, it may be advantageous to upgrade the biogas. In this way, the carbon dioxide as well as various impurities are removed and biomethane is produced. Biomethane is similar to natural gas and can be used in si
Solid fuel fired fluidized bed (FB) boilers are common in combined heat and power (CHP) plants in district heating- and process industry. In this study, utilization of such FB boilers for production of syngas in dual fluidized bed gasifiers and subsequent catalytic biofuel production to substitute natural gas (SNG), methanol (MeOH) and Fischer-Tropsch fuel (FT) has been examined. Based on the hypoSolid fuel fired fluidized bed (FB) boilers are common in combined heat and power (CHP) plants in district heating- and process industry.

Lokshtanov, Marx, and Saurabh SODA 2011 proved that there is no (k-epsilon)^pw(G)poly(n) time algorithm for deciding if an n-vertex graph G with pathwidth pw admits a proper vertex coloring with k colors unless the Strong Exponential Time Hypothesis (SETH) is false, for any constant epsilon>0. We show here that nevertheless, when k>lfloor Delta/2 rfloor + 1, where Delta is the maximum degree in th
Vehicle availability data is emerging as a potential data source for micro-mobility research and applications. However, there is not yet research that systematically evaluates or validates the processing of this emerging mobility data. To fill this gap, we propose a generally applicable data processing framework and validate its related algorithms. The framework exploits micro-mobility vehicle ava
Aim: According to the Cognitive Model of Insomnia, engaging in sleep-related cognitive processes may lead to sleep problems over time. The aim was to examine associations between five sleep-related cognitive processes and the incidence of insomnia, and to investigate if baseline anxiety and depression influence the associations. Methods: Two thousand three hundred and thirty-three participants com
Background: Many people are dying from coronavirus disease 2019 (COVID-19), but consensus guidance on palliative care in COVID-19 is lacking. This new life-threatening disease has put healthcare systems under pressure, with the increased need of palliative care provided to many patients by clinicians who have limited prior experience in this field. Therefore, we aimed to make consensus recommendat
In this study, static coefficients of friction for laminated veneer lumber on steel surfaces were determined experimentally. The focus was on the frictional behaviors at different pressure levels, which were studied in combination with other influencing parameters: fiber orientation, moisture content, and surface roughness. Coefficients of friction were obtained as 0.10–0.30 for a smooth steel sur
Introduction: The Assessment of Learning Powered mobility use (ALP) tool including the ALP instrument and facilitating strategies, was developed for Driving to Learn. This therapeutic intervention aims to provide children and adults who have profound cognitive disabilities with opportunities to learn tool use through powered mobility practise. To allow for longer intervention periods, a partnershi
The efforts to develop a dopamine cell replacement therapy for Parkinson's disease have spanned over more than three decades. Based on almost 10 years of transplantation studies in animal models, the first patients receiving grafts of fetal-derived dopamine neuroblasts were operated in Lund in 1987. Over the following two decades, a total of 18 patients were transplanted and followed closely by ou
The compelling images and promises attached to autonomous drive vehicles can easily create an impression that one can speak of a radical distinction between a self-driving future and a manual-driving present. Yet today’s drivers can already refer to their everyday driving as being experienced as though on ‘auto-pilot’, in which they are able to drive their cars while lost in things such as daydrea
