Pressurized Hot Water Extraction (PHWE) is a quick, efficient and environmentally friendly technique for extractions. However. when using PHWE to extract thermally unstable analytes, extraction and degradation effects occur at the same time, and thereby compete. At first, the extraction effect dominates, but degradation effects soon take over. In this paper, extraction and degradation rates of ant

The surface structure of Pd(100) during CO oxidation was measured using a combination of a flow reactor and in situ surface X-ray diffraction coupled to a large-area 2-dimensional detector. The surface structure was measured for P-O2/P-CO ratios between 0.6 and 10 at a fixed total gas pressure of 200 mbar and a fixed CO pressure of 10 +/- 1 mbar. In conjunction with the surface structure the react

The effect of a supercritical carbon dioxide (scCO(2)) treatment on the free volume of poly[1-(trimethylsilyl)-1-propyne] (PTMSP) and PTMSP-silica nanohybrid membranes was investigated with positron annihilation lifetime spectroscopy (PALS) and correlated with their performance in pervaporation. Treatment of dense unfilled PTMSP and silica filled PTMSP (2.5, 10 and 20 wt.% silica) membranes with s

Bio-energy production from lignocelluloses biomass has gained a lot of interest in recent years. Miscanthus sp. are high lignocelluloses biomass yielding with relatively high carbohydrate content cultivable on different soils and under climatic conditions. However, the lignocellulosic nature means that cellulose and hemicellulose are cover by lignin network that might limit hydrolysis. In this stu

This Letter presents the results of a search for a heavy particle decaying into an e(+/-)mu(+/-), e(+/-)tau(+/-), or mu(+/-)tau(+/-) final state in pp collisions at root s = 7 TeV. The data were recorded with the ATLAS detector at the LHC during 2011 and correspond to an integrated luminosity of 4.6 fb(-1). No significant excess above the Standard Model expectation is observed, and exclusions at 9

In the robotic manipulation context, end-effector contact forces may be difficult to measure mainly due to the tool dynamic interferences Such as the inertial forces. In this paper, a whole methodology is proposed to estimate these forces. The new approach is based oil a sensor fusion technique that integrates the information of a wrist force sensor. of a 3D accelerometer placed at the robot tool

Twelve fossil species of Proteaceous pollen, predominantly attributable to Proteacidites and Beaupreaidites, were recovered from the Maastrichtian-Paleocene sedimentary succession of the Garden Cove Formation on Campbell Island, the southernmost landmass of the Zealandia continent. Among these are two new species, Proteacidites campbellensis and Proteacidites hortisinus. The high diversity of Prot

Isothermal (heat conduction) calorimetry is a general technique to study processes through the thermal power they produce. This paper deals with operational issues concerning isothermal calorimeters. In this paper it is shown that steady-state and pulse calibrations give the same result; that the use of mobile heaters (placed in the reaction ampoule) give more accurate results than fixed heaters (

The results of a round robin test on isothermal (heat conduction) calorimetry are presented. A total of 18 participants using three types of instruments conducted 3-day measurements of the hydration of one rapidly hardening Portland cement and one slag-containing cement. The results confirm that isothermal calorimetry is a suitable method for the determination of heat of hydration. As a part of th

The release of dissolved silicon (DSi) from A and B horizons was investigated with leaching tests on unsaturated columns. As forest A horizons have larger biogenic Si (BSi) pools than arable lands, we compared the Si release from a forest and a cropland from the same geographical region developed on a Luvisol in Belgium and a Cambisol in Sweden. The A horizons released a quickly dissolving Si frac

The Master Thesis, which is a part of the education to become Master of Science in Engineering, Industrial Engineering and Management, Faculty of Engineering, Lund University, has been written at Gambro in Lund. In 2006 new owners bought Gambro and Gambro has been working on new guidelines and strategies during the past year. The Master Thesis became a part of the work with new strategies and ther

Problem background: The past few years, banks have gone from only being lenders and borrowers of money to also cover a broad portfolio of offers to customers. Banks today supply their customers with several investment alternatives for the savings capital. It is a fierce competition at the financial market and the employees must continuously keep up to date with all the new information and knowledg

There are many immigrant women living in Sweden today who come from cultures in Africa where Female Genital Mutilation is tradition. Due to the many complications of this tradition and due to inadequate knowledge of the tradition and management of its complications within the healthcare system, it is one of the biggest health problems of our time. The aim of this study was to gain knowledge and un

Tillverkning av batterier är en mycket komplex process och det är en process som Saft AB är väl förtrogen med. För att kunna producera det antal batterier Saft AB gör måste de se till att alla led i produktionen håller en viss standard. Detta projekt hade i mål att utveckla ett användarcentrerat, interaktivt verktyg för Saft AB med förmågan att övervaka och analysera data som samlas in av sensorerThe production of batteries is a substantially complex process, and it is a process with which Saft AB is greatly familiarised. In order to produce the number of batteries Saft AB does, they need to ensure that all stages of production adhere to a certain standard. This project’s purpose aimed to develop a user focused, interactive tool for Saft AB with the capability to monitor and analyse the da

This thesis addresses teachers' perspectives on Computer Algebra Systems (CAS) in their teaching in upper secondary mathematics in the Faroe Islands. The aim is to investigate to what extent teachers view CAS as a pragmatic calculating tool or as a contribution to mathematical learning and in addition how they see CAS affecting students’ modelling and representational skills. Eight mathematics

The purpose of this essay is to investigate how social workers assess whether the care with the Swedish legislation, Care of young persons act, LVU, should be terminated. And also to examine what measures and support are given to the biological parents after the application of LVU. To examine this a semi-structured, qualitative interview took place where four social workers from a town in the sout

Syftet med uppsatsen är att skapa förståelse samt redogöra över hur bankerna i den svenska marknaden redovisar humankapital (HK). Vidare vill vi belysa över utveckling av HK redovisning under år 2020 i jämförelse med år 2010. Studiens metod bygger på en longitudinell studie där syftet är att belysa hur valda bankerna i den svenska marknaden redovisar sin HK samt hur har redovisningen utvecklats i This study is to create an understanding on how banks in the Swedish market report their human capital (HC). Furthermore, we highlight the development of HC reporting during the year 2020 in comparison with 2010. The study method is based on a longitudinal study where the purpose is to shed light on how selected banks in the Swedish market report their HC and how the accounting has developed in co

Purpose: This thesis aims to evaluate whether the ECB’s Pandemic Emergency Purchase Programme (PEPP) cushioned the Covid-19 crisis’ impact on the Euro area’s corporate bond market and relieved borrowing conditions. Methodology: The methodology is based upon unbalanced panel data and difference-in-differences regressions with firm-clustered standard errors. The model controls for industry and cou

The purpose of the study has been to look into what relatives of people with addiction problems specify as good relative support. Furthermore, we have investigated whether there are differences between groups such as; women and men as well as external and internal coping strategies linked to stress management in what the respondents perceive as good relative support. We have also investigated whet
