This paper presents measurement results of electricity use and lighting conditions in individual office rooms located in Lund, Sweden. The aim is to demonstrate the energy saving potential by using different lighting systems and the satisfaction of users. The measurements are carried out in one empty reference room and four fully occupied test rooms equipped with different electric light control s

The possibility to reduce dependence on fossil fuel resources has led to an increasing interest in the use of bio-fuels. This study builds on earlier work on (aromatic) cyclic oxygenates [1,2], but a far wider window of engine operation has been investigated in this paper. Two parametric variations of engine operation were performed and discussed: (1) non-EGR operation by means of varying the load

Context: Prostate cancer (PCa) is one of the most common human malignancies and arises through genetic and epigenetic alterations. Epigenetic modifications include DNA methylation, histone modifications, and microRNAs (miRNA) and produce heritable changes in gene expression without altering the DNA coding sequence. Objective: To review progress in the understanding of PCa epigenetics and to focus

Classification of speed profiles is necessary to allow interpretation of automatic speed measurements in terms of road user behaviour. Aggregation without considering variation in individual profile shapes easily leads to aggregation bias, while classification based on exogenous criteria runs the risk of loosing important information on behavioural (co-) variation. In this paper we test how three

This study investigates the impact of supports and synthesis routes on the performance of supported gold nanoparticles in the Sonogashira coupling reaction. The catalysts were synthesized by deposition-precipitation (DP) and incipient wetness impregnation (IMP), employing carriers of different nature (redox: CeO2, TiO2, and non-redox: Al2O3) and were characterized by various physical techniques su

Popular Abstract in Swedish Avhandlingen är en tematisk och historisk studie av Sjömans filmer och av hans betydelse för svensk filmkultur, framför allt under 1960- och 1970-talen. Sjöman är mest känd som filmregissör. År 1962 hyllades debutfilmen Älskarinnan av kritikerna. Sjöman sågs som föregångare till en ny våg i svensk film. Genom debatten efter filmcensurens totalförbud av 491 (1964) kom Sj

Popular Abstract in Swedish Reglering av celltillväxt och celldöd är mycket viktigt för bibehållandet av balansen mellan antalet olika celler i kroppen. Om regleringen rubbas kan olika sjukdomar uppkomma, som karakteriseras av för mycket celltillväxt eller av för mycket celldöd. Exempel är cancer, där man har för mycket tillväxt, samt många degenerativa sjukdomar som diabetes, Parkinsons och aids,

Prostate-specific antigen (PSA) is a glycoprotein produced by the prostate gland. It occurs in several molecular forms in the blood and assays have been developed to measure free PSA and PSA in complex with alpha-1-antichymotrypsin (PSA-ACT). Higher proportions of free PSA (PSA-F/T) in blood are found in subjects with benign prostatic hyperplasia (BPH) as compared to cancer patients. Utilizing imm

Popular Abstract in Swedish 1: Tomas Åkerud, doktorand vid Lunds Universitet, har utvecklat en metod för att mäta hur snabbt läkemedelsmolekyler och fettsyror (de naturliga bindarna) tar sig in i och lämnar bindingsfickan i ett protein som är viktigt för fettsyrametabolismen i människa. Proteinet, adipocyt-fettsyrabindande protein (A-FABP), har som funktion att transportera fettsyror, som inte är Nuclear magnetic resonance spectroscopy (NMR) has been used to determine the kinetics of ligand binding to the adipocyte fatty acid-binding protein (A-FABP), as well as the oligomerisation and inter- and intramolecular dynamics of the low molecular weight-protein tyrosine phosphatase (LMW-PTP) in solution. NMR spectroscopy is sensitive to dynamic processes on timescales ranging from picoseconds t

Value added tax (VAT) is a key part of the fiscal revenue of many countries. Yet this broad-based tax on consumer spending exempts financial services. This seems puzzling to many, particularly given the significance of that sector and the size of its value-added in today's world economy. The fact that the European Commission is currently reviewing the tax treatment of financial activities in the E

The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. The apparent persistency of the radical cation of hexamethylbenzene was due to the slow oxidation when thallium(III) trifluoroacetate was

The essay deals with various problems concerning the regulation aiming to protect the Swedish Tax Base with respect to the unrealized appreciation accrued in shares in Swedish companies. According to the ECJ ruling in X and Y case there can be no immediate taxation of an individual shareholder of a Swedish company if the transfer at undervalue of the company shares is to a foreign legal person who

Authors: Rebecka Werngren and Sofia Ekblom Title: The last way out. A qualitative study of how social workers reach a motion about compulsory institutional care for youth. [translated title] Supervisor: Claes Levin The purpose of this study has been to examine social workers opinion about compulsory institutional care for youths. The aim has been to recognize how professionals reach decisions abo

The aims of the thesis are to investigate the estimation power and the normality of standardized residuals for Generalized autoregressive conditional heteroscedasticity models (GARCH). We facilitate the analysis by only dealing with GARCH(1, 1) models. We take use of MATLAB as the statistical programming tool for the simulation of the data and the estimation. We define the meaning of estimation

Today, drug assisted treatment of Methadone and Subutex is well established in Swedish society. However, it has since the late 1960´s been differing perceptions of both the pros and cons on drug assisted therapy. The purpose and aim of this study was to explore and describe what kind of ethical attitudes social workers and representatives of the Swedish Drug Users Union (SDUU) usually have around

Private equity is a relatively new and unexplored business in Sweden. The aim of our thesis is to explore the factors influencing the internationalization of Swedish private equity firms. Why do the firms chose to internationalize? To what degree are the firms internationalized? What have driven the firms to internationalize to the current extent? Furthermore we aim to map the structure of the int

This masters' thesis, "The New Economy of Vision : New Urban Spaces in post-1992 Shanghai", authored by Johan Vaide, draws on the economic reforms initiated in the late 1970s to show how Shanghai has experienced a rapid and well-calculated change of its cultural landscape. Due to the launch of "socialism with Chinese characteristics" in 1978 and the construction of an entir

The task consisted in helping Tetra Pak with the problem that they today have with unexplained deformation of their creasing carriages. Tetra Pak uses different carriages depending on which kind of packaging that is to be manufactured. The carriages are hauled in and pulled in to the production line when another type of packaging is to be manufactured. Basically the carriages look the same, the th

A novel design of a biochemical oxygen demand (BOD) biosensor has been developed for on-line monitoring of easily biodegradable organic compounds in aqueous samples. The biological recognition element of the sensor could be easily renewed by injecting new bacterial paste without disassembling the sensor system. The sensor measurements were carried out in the initial-rate mode using a flow injectio
