5-Hydroxymethylfurfural (HMF), a product of catalytic dehydration of C6 sugars, is a versatile and key renewable platform chemical. The possibility to use a high substrate concentration with high yield in a single-solvent system is one of the solutions to reduce solvent usage, energy consumption, reaction volume, and operating cost. A heterogeneous catalyst and single-solvent system were employed
A new simple, reproducible and sensitive ELISA that uses trichloroacetic acid (TCA) for the coating of lipooligosaccharide (LOS), smooth lipopolysaccharide (LPS) or lipid A to the solid phase has been developed. The experimental parameters (temperature of coating, time of coating, antigen concentration and TCA concentration) were evaluated by a complete factorial design (24). As a result of the ev
Adsorption of different lipases by EP-100 polypropylene powder from pure and pure lipase preparations was studied. Langmuir isotherms described the adsorption equilibria well both for protein and lipase activity adsorption. Adsorption isotherms for five different proteins all gave a similar saturation level of 220 mg protein per g carrier. Twelve commercial lipase preparations were tested for sele
Background: The mandibular symphysis is a true joint with a fibrocartilage disc stabilizing both ramus of mandible. The mandibular fracture occurs in 15% of all cases of fracture in cats, and of these, 73% correspond to fracture of the mandibular symphysis. There is a technique for stabilization of symphysis fracture using a nylon cable tie band, however it is necessary to perform two lateral inci
Cytogenetic analysis using Giemsa banding technique was successful in 30 of the 49 adult patients with nonHodgkin lymphomas investigated. The results are correlated with previous findings in 48 non‐Hodgkin lymphoma patients studied by means of fine needle aspiration in our laboratory. As 8 patients were included in both series, the total number successfully investigated was 70. The success rate wi
We have earlier shown that radio frequency electromagnetic fields can cause significant leakage of albumin through the blood-brain barrier of exposed rats as compared to non-exposed rats, and also significant neuronal damage in rat brains several weeks after a 2 h exposure to a mobile phone, at 915 MHz with a global system for mobile communications (GSM) frequency modulation, at whole-body specifi
Previous experiments demonstrated improved outcome following prolonged cerebral ischemia given controlled brain reperfusion using extracorporeal circulation. The current study further investigates this. Young adult pigs were exposed to 30 min of global normothermic cerebral ischemia, achieved through intrathoracic clamping of cerebral arteries, followed by 20 min of isolated mechanical brain reper
Avocado crop in Tanzania is sparingly investigated regardless of being an important fruit commodity. This study was undertaken to explore the yield and the value chain of this crop in the country. Data were collected mainly by face-to-face interviews with 275 avocado farmers, 231 avocado traders and 16 key informants. Descriptive statistics, Chi-square test and one-way analysis of variance were us

Speed control is the most important aspect of promoting road safety world-wide. The question is how are speeds developing? The European Transport Safety Council concludes: There is little progress on reducing speeds in Europe. Similar conclusions can be drawn from the US and Australia. Attitude surveys show that people’s answers are not very consistent and represent statements without any strong b
Introduction: Secundum atrial septal defect is one of the most common congenital heart defects. Previous paediatric studies have mainly addressed echocardiographic and few clinical factors among children associated with adverse events. The aim of this study was to identify neonatal and other clinical risk factors associated with adverse events up to one year after closure of atrial septal defect.
An anthropomorphic phantom study was carried out in 2013-14 in two hospitals, one located in Russia (Mariinsky Hospital, Saint Petersburg) and the other in Sweden (Skåne University Hospital, Malmö). The aim of the study was to investigate the possibilities to reduce the patient dose from digital X-ray chest screening examinations. The existing chest imaging protocols were adjusted by changing the
BACKGROUND AND AIMS: The optimal position for pH electrode placement in the diagnosis of gastroesophageal reflux disease (GERD) is unknown. The aim of this study was to evaluate the discriminatory power of targeted pH recording immediately above the squamocolumnar junction (SCJ) and to compare the results with those obtained by simultaneous recording at the conventional level for pH monitoring. SU
Syftet med denna avhandling är att undersöka användningen av naturrättsligt språkbruk i de danska agrarreformerna, cirka 1750-1800. Detta görs genom en social kontextualisering som fokuserar på de sprickor som fanns i det danska samhället före och under reformperioden. Jag hävdar att dessa huvudsakligen utgjordes av interna materiella skillnader inom den danska jordägande eliten, inklusive deras oPopular science description The agrarian reforms of the 18th century were some of the most momentous historical events in Danish history. In the span of 30 years, half of all peasants went from living in a state of serfdom to owning and cultivating their own plots of land, free from the onerous ties of manorial dependence that they had toiled under for hundreds of years. In this pioneering dissert
The questions about why and how senescence occurs in the wild are among the most pertinent ones in evolutionary ecology. Telomere length is a commonly used marker for aging, while other biomarkers of aging have received considerably less attention. Here we studied how another potent indicator of aging-skin pentosidine concentration-relates to age and blood telomere length in a long-lived seabird w
Category housing is an example of forms of housing that belong to the organized work of providing residences for persons who for diverse reasons cannot obtain them on the ordinary housing market. In the organizing of the practical social work that is carried out for this purpose, categorization serves as an important tool for connecting the available housing alternatives with the individuals who s
Popular Abstract in Swedish Ekokardiografisk undersökning av hjärtat utvecklades i Lund i början av 1950 talet av kardiologen Inge Edler tillsammans med fysikern Helmuth Hertz och har under de första 30 åren huvudsakligen utförts via bröstkorgsväggen så kallat transthorakalt ultraljud. Under 1980 talet utvecklades tekniken och man fick instrument som via matstrupen kunde utföra en ekokardiografiskThe subject of this thesis is the clinical use of transesophageal echocardiography (TEE) in patients with stroke or atrial fibrillation. Subjects were examined with echocardiography and sonography of the carotid artery. A control group of randomly selected volunteers without cerebrovascular disease was compared to patients with ischemic stroke. Cardiac pathology was classified as minor potential e
Popular Abstract in Swedish Arcanobacterium haemolyticum (A. haemolyticum) beskrevs för första gången under namnet Corynebacterim haemolyticum av MacLean och medarbetare 1946. Bakterien odlades fram från svalget hos patienter med halsont och från sår. Patienterna bestod av amerikanska soldater och infödda öbor i Stilla havet. Från olika delar av världen har senare beskrivits halsont och utslag hosIn an 18-month period all throat cultures in our laboratory were examined for Arcanobacterium haemolyticum and clinical information was obtained. The great majority of the patients suffered from pharyngitis or tonsillitis, accompanied by a rash in 46% of cases. One third of the patients had a history of recurrent tonsillitis. Three types of exanthema was described, scarlatiniform, urticarial and e
Aim: To value the importance of research on avian migration for the development and current status of Spanish ornithology. Results and Conclusions: Avian migration has always been an outstanding field in ornithology. This assertion is particularly true in Spain, as we illustrate here by discussing the contribution of migration research to both the scientific and historical development of Spanish o
Digital image correlation (DIC) can measure full-field surface strains during mechanical testing of hard and soft tissues. When compared to traditional methods, such as strain gauges, DIC offers larger validation data (similar to 50,000 points) for, e.g., finite element models. Our main aim was to evaluate the repeatability of surface strain measurements with DIC during compressive testing of comp
