Treatment of landfill leachate has gained increasing attention during recent years, and several commercial RO leachate treatment plants have been installed in, e.g., Germany, the Netherlands and Switzerland. in this investigation the influence on membrane performance when treating new types of landfill leachate was studied. Three different types of landfill leachate were included in this study: le
A method based on three-phase hollow fiber liquid phase microextraction was developed and successfully applied to aerosols for the analysis of lignin pyrolysis acids such as syringic acid, vanillic acid and p-salicylic acid. Important parameters related to extraction process like organic solvent for membrane phase, tri-n-octylphosphine (TOPO) oxide contents in organic solvent, stirring speed, extr
Popular Abstract in Swedish Kalcium är inblandat i många viktiga processer i kroppen. Kalciumbindande proteiner är viktiga i detta sammanhang. Det finns ofta en vattenmolekyl med på bindningsstället i proteinet och vi har studerat hur den påverkar bindningsegenskaperna. Kalcium är inblandat i många viktiga processer i kroppen. Kalciumbindande proteiner är viktiga i detta sammanhang. Jag har stude
DNA chemical and physical networks have been investigated with respect to their stability and swelling, and rheological properties. Chemical networks were prepared by cross-linking DNA with ethylene glycol diglycidyl ether (EGDE), and physical networks by association with cationic polymers. Both types of gels display strong elastic properties and have a shear thinning behaviour. Addition of cation
Popular Abstract in Swedish Transporter är viktiga för ett fungerande samhälle, men samtidigt innehåller avgaserna från en förbränningsmotor farliga utsläpp som förorenar vår miljö. Kan vi på något sätt hindra att miljön blir förstörd av farliga utsläpp genom förbättrad motordesign? Frågan om global uppvärmning har varit vid liv enda sedan IPCC (Intergovernmental Panel on Climate Change) grundadeThis thesis concerns a numerical investigation on heat transfer in internal combustion engines, with the aim of increasing engine efficiency. The efficiency gains are to be extracted from reduced heat transfer losses, by increasing the knowledge on how the heat transfer process is affected by various hardware and operational parameters in the engine. The engines concerned are both conventional die
That a load balancing strategy using stale information care lessly will incur system performance degradation is easy to verify. However it is not so obvious that routing a customer to the expected shortest queue has the same problem when information for decision is stale. We consider a queueing system with a load balancer and a pool of identical FCFS queues in parallel. The arrival process is assu
Popular Abstract in Swedish Potatis är ett av våra viktigaste baslivsmedel, men erbjuder trots det stor variation. Traditionella recept varvas med nya innovationer i hushåll och restauranger, och inom livsmedelsindustrin processas potatisen till en rad olika produkter. Från traditionell kokt potatis med sås inom husmanskosten har våra matvanor förändrats radikalt. Ökade krav på snabb och enkel tilThe potato is one of our most important food crops, being sold in its natural state or processed into a wide range of products. Starch, by far the most abundant component in the tuber, is greatly affected by heat processing. Therefore it is logical to study starch thermal properties within the tuber tissue, although most previous studies have focused on starch-water model systems. One of the main
Lead(II) acetate [Pb(Ac)2, where Ac = acetate group (CH3-COO-)2] is a very common salt with many and varied uses throughout history. However, only lead(II) acetate trihydrate [Pb(Ac)2·3H2O] has been characterized to date. In this paper, two enantiotropic polymorphs of the anhydrous salt, a novel hydrate [lead(II) acetate hemihydrate: Pb(Ac)2·1/2H2O], and two decomposition products [corresponding t
The concept of a bioeconomy can be understood as an economy where the basic building blocks for materials, chemicals, and energy are derived from renewable biological resources. Biorefineries are considered an integral part of the development toward a future sustainable bioeconomy. The purpose of this literature review is to synthesize current knowledge about how biorefinery technologies are being
In spark assisted homogeneous charge compression ignition (SACI) engines a premixed flame is first established; the propagating flame results in compression heating of the end gas and finally auto-ignition of the gas. Two dimensional direct numerical simulation (2D DNS) and one dimensional (1D) detailed simulations of flame/spontaneous ignition interaction in a lean hydrogen/air mixture under a co
Det svenska Lagrådet har uppgiften att granska lagar under lagstiftningsarbetet. Det bildades 1909 eftersom Högsta domstolen, som tidigare hade denna roll, var överbelastat av alla de nya lagar som skapades. Under det dryga sekel som det svenska Lagrådet har existerat så har det skett ett antal förändringar. Denna uppsats analyserar vilka förändringar som har skett och varför. Den jämför även detThe Swedish legal council is responsible for legal preview in the Swedish process for creating new laws. It was created 1909 because the supreme court, which was previously responsible for legal preview, was overrun by the amount of new laws. During the roughly one hundred years that the legal council has existed, a number of changes have been made. This essay analyses which changes have come to
Changes in Sweden’s migration and asylum policies are constantly occurring as a topic in the political debate. When a foreigner hands in their asylum application to the Swedish Migration Agency a decision must be made rather quickly. It has become a common issue for unaccompanied children to prove their identity. The part of the identity that matters the most for the Swedish Migration Agency is th
The industrial sector in Sweden accounted for 38 percent of the country’s total energy consumption in 2019. As the world’s focus has shifted drastically on energy consumption, the industry sector’s has as well due to energy initiatives and government-driven regulations. The energy issue is currently of great relevance for energy-intensive industries where enormous potential remains due to factors
Combustion of fossil fuels is single-handedly the largest contributor of global warming. The transportation sector is responsible for about a third of the greenhouse gas emissions yearly in Sweden. In turn, road traffic makes up the largest share within the transportation. The Swedish government has set out an ambitious goal to reduce domestic carbon emissions caused by the transportation sector
The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.
Utgångspunkten för den svenska rättsordningen är att enskilda inte ska be-höva anlita juridiskt biträde eller ombud för att föra sin talan hos myndighet eller domstol. Skatteförfarandet och skatteprocessen är, precis som övriga förvaltningsförfarandet och förvaltningsprocessen, som huvudregel skriftlig. Grundtanken är att beslutsmyndigheternas utredningsansvar (officialprinci-pen) tillsammans med
Down to the roots is a project about just that; seeing where things come from and how are they made. I have a background in textile design which I wanted to enhance in this project. Therefore I wanted to examine the technique of tufting. This is a textile technique that is not talked about that much, but most of today’s carpets are made this way. In tufting threads are shot into a fabric, situate
After the General Court’s (GC) decision in case T-472/13 H. Lundbeck A/S and Lundbeck Ltd v Commission it seems the concept of potential competition in the context of so-called ‘pay-for-delay’ agreements, or reverse patent settlements, might have been altered; that the bar in order for an undertaking to qualify as a potential competitor might have been lowered. This thesis aims to examine whether
This study looks at how political regimes affect income inequality. Levels of inequality differ a lot between countries but tend to be very stable over time in a country. This is in line with explanations of inequality that focus on structural factors, of which political regimes could be one. The model used in this study is based on the selectorate theory, which states that the size of the group t
This Master’s thesis in library and information science deals with the development of Länkskafferiet, a SBIG created in 1994 by NetLab of the University Library of Lund. Länkskafferiet maintains a selection of quality controlled Internet links for the use of Swedish school children. We have had access to archives and files from the start of Länkskafferiet in 1994 to 2005 and have also interviewed
