BACKGROUND: The current trend of upgrading undervalued agricultural by-products involves the recovery of natural antioxidants. The purpose of this study was to recover phenols from fresh olive mill wastewater (OMW) with their dispersion in 85 mL ethanol per 100 mL and to investigate the effect of processing parameters on the phenol content and antioxidant capacity of the extracts. Moreover, all th

During the last 35 years almost 5000 ceramic thin-sections have been analysed at the Laboratory for Ceramic Research, Lund University and of those have 1650 analyses been performed on material from the Iron Age in Northern Europe (here c. 500 BC-1100 AD). Currently there is a project to register these analyses in a database and evaluate the results. We can for the first time get an overall picture

The installation of technical solutions for heat recovery from the ventilation air is a very important step, both with respect to improving the indoor climate and as an energy-saving measure. Ventilation without heat recovery use a substantial part of an entire building's heating use, especially if the building is a low energy building. To realize a large implementation of heat recovery property o

Background: Tamoxifen treatment has previously been reported to confer life-prolonging effects in patients with advanced pancreatic cancer, and most evidently so in women. None of these trials did however include biomarkers, and the relevance of female hormone signaling in pancreatic or other periampullary adenocarcinoma remains largely unexplored. The aim of this study was to examine the extent a

Describing the motion in a vertical roller coaster loop requires a good understanding of Newton's laws, vectors and energy transformation. This paper describes how first-year students try to make sense of force and acceleration in this example of non-uniform circular motion, which was part of a written exam. In addition to an analysis of the exam solutions by about 60 students, a group interview w

Populärvetenskaplig sammanfattningAluminium används för en stor mängd produkter, allt från hus och i fordon till såvardagliga produkter som aluminiumburkar. Det breda användningsområdet beror på aluminiumets höga hållfasthet, lätta vikt och dess goda korrosionsmotståndighet. Korrosionsmotståndet beror på att när aluminium exponeras för luft bildas ett aluminiumoxidskikt på ytan, vilket skyddar aluAbstractIn this thesis, the electrochemical deposition process of Sn into ordered nanoporous anodic aluminium oxide (NP-AAO) have been studied. The deposition process was studied in situ using the X-ray techniques: X-ray diffraction (XRD), Grazing incidence Transmission Small-Angle X-ray Scattering (GTSAXS), X-ray Fluorescence (XRF) and X-ray Absorption Near Edge Structure (XANES) and ex situ usin

Recent evidence shows that rising wage inequality in industrialized countries can partially be attributed to trade integration. However, it is unclear what the mechanisms behind this relationship are. Previous explanations pointed towards the displacement of mid-wage manufacturing workers as a response to rising imports. But for Germany it has been shown that rising exports likewise create manufac

Whether optoelectronic devices based on metal-halide perovskite semiconductors will become a commercially viable technology will be determined by their intrinsic and operational stability. Recent results indicate there is some reversibility of perovskite degradation in thin films and devices, although mechanistic insight into the processes driving degradation and recovery are still scarce. We here

Objectives: Pericarditis, takotsubo cardiomyopathy and early repolarization syndrome (ERS) are well-known to mimic ST elevation myocardial infarction (STEMI). We aimed to study whether ECG findings of reciprocal ST depression, PR depression, ST-segment convexity or terminal QRS distortion can discriminate between ST elevation due to ischemia and non-ischemic conditions. Design: Eighty-five patient

We study the spectral phase introduced by parametric amplification and how high extraction efficiency of energy leads to deterioration of the phase. Avoiding this regime, and using a pulse shaper, we achieve high-contrast ultrashort pulses.

Building Information Modelling (BIM) objects represent building products in design, simulation, and procurement processes. This paper explores how BIM objects could be created and exchanged to enable the diffusion of innovative products with enhanced sustainability performance. Two BIM library platforms were examined by taking a new approach that integrates the concepts of sustainable value, diffu

Pulmonary arterial hypertension is a severe disease for which diagnosis often is delayed. Matrix metalloproteinases have been suggested to play a role in vascular remodeling and pulmonary hypertension development. Our aim was therefore to investigate the potential role of matrix metalloproteinases as biomarkers in diagnosis and differentiation of pulmonary arterial hypertension in relation to vari

Pollinators play an important role in terrestrial ecosystems by providing key ecosystem functions and services to wild plants and crops, respectively. The sustainable provision of such ecosystem functions and services requires diverse pollinator communities over the seasons. Despite evidence that climate warming shifts pollinator phenology, a general assessment of these shifts and their consequenc

The majority of studies on mental health in deaf and hard-of-hearing (DHH) children report a higher level of mental health problems. Inconsistencies in reports of prevalence of mental health problems have been found to be related to a number of factors such as language skills, cognitive ability, heterogeneous samples as well as validity problems caused by using written measures designed for typica
