An amphiphilic graft copolymer, with hydrophilic poly(ethylene glycol) monomethyl ether side chains grafted onto a hydrophobic poly(dodecyl methacrylate) backbone, has been synthesized. The side chains are water soluble and the backbone is soluble in oils such as cyclohexane and isooctane. The graft copolymer is not soluble in oil or water, but it is quite soluble in AOT oil-continuous microemulsi
The isolation of male and female DNA is an important step in the analysis of sexual assault evidence. A vaginal swab with female epithelial cells and male sperm cells is obtained from the female, and it is vital to separate the male and female fractions in order to obtain a single-source DNA profile of the suspect. In the case of a low abundance of sperm cells, it is very important that no cells a
In this paper, we investigate the impact of power amplifier (PA) nonlinear distortion in pre-coded multi-user large antenna or massive MIMO downlink systems. First, detailed signal and system models are derived for the received signal at single-antenna user equipment (UE) under channel-aware linear precoding in the base-station combined with behavioral models for the individual PA units, covering
Popular Abstract in Swedish Papillomvirus infekterar ett brett spektrum av ryggradsdjur, såsom människa, olika ap-arter, ko, älg, elefant, ren och bofink. Dessa virus kan ge så vitt skilda symptom som cancer och vårtor. De indelas efter vilken art de infekterar, och inom arterna efter skillnad i DNA-sekvens mellan olika isolat (typer). Hittills har 92 humana papillomvirus (HPV) typer beskrivits, oPapillomaviruses are a diverse, epitheliotropic group of viruses. Some genotypes are the main cause of anogenital cancer in humans; others can induce skin lesions. In order to investigate the occurrence of subclinical skin infections with human papillomavirus (HPV), a pair of degenerate primers (FAP59/64) was designed. Moist cotton-tipped swabs were used as a gentle method of sample collection. Di
Popular Abstract in Swedish Denna avhandling sammanfattar studier av en ny biologisk markör för påvisande av alkoholmissbruk. Alkoholmissbruk är ett omfattande hälsoproblem i många delar av världen och Sverige är inte på något sätt undantaget. Man har beräknat att ca 15% av alla män och 10% av alla kvinnor i detta land står för hälften av all alkoholkonsumtion. Det föreligger alltså en onormal förBiological markers offer a way of assessing ethanol intake and determining whether a health problem is alcohol related. This study investigated the use of phosphatidylethanol (PEth) in blood as a new marker of alcohol abuse. PEth is an abnormal phospholipid, formed only in the presence of ethanol via the transphosphatidylation reaction of phospholipase D (PLD). A new HPLC-evaporative light scatter
Popular Abstract in Swedish VIKTEN AV HETEROGENA JORDBRUKSMILJÖER FÖR GRÅSPARVEN Under de senaste 40 åren har vårt odlingslandskap genomgått kraftiga strukturella förändringar som en konsekvens av att jordbruket har intensifierats och effektiviserats. Dessa förändringar har möjliggjort en nödvändig, ökad produktion av spannmål och andra grödor men samtidigt har det haft förödande konsekvenser på dStrong declines of European farmland birds in recent decades are assumed to be caused by decreased food availability resulting from agricultural intensification and concomitant loss of farmland heterogeneity. One of the species suffering particularly strong declines in NW European countries is the house sparrow. In this thesis I investigated the importance of farmland land-use on house sparrow eco
Popular AbstractI avhandlingen undersöks den ekonomiska omvandlingsprocess som skett i Sverige sedan mitten av 1970-talet. Av speciellt intresse är hur och varför de fördelar som företag och branscher åtnjuter på grund av samlokalisering med andra ekonomiska aktörer (så kallade agglomerationsexternaliteter) varierar över olika faser av ekonomisk omvandling. Avhandlingen baserar sig på de framsteg This thesis investigates the process of economic transformation taking place in Sweden since the mid 1970s. Especially, it is concerned with how and why benefits that firms and industries draw from regional co-location with other actors (agglomeration externalities) vary over stages of economic transformation. Drawing on recent findings within the fields of evolutionary economics and evolutionary
Popular Abstract in Swedish Den huvudsakliga hämmande signalsubstansen i hjärnan är GABA (gamma-aminobutyric acid, gamma-aminosmörsyra). GABA finns i ungefär hälften av alla nervceller i hjärnan och alla nervceller i hjärnan antas ha receptorer som binder GABA. Om man tänker på alla de normala neurologiska funktioner samt rubbningar där GABA är involverat är det inte svårt att förstå GABA:s oerhörInhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). In this thesis the functional and pharmacological properties of GABAA receptors expressed in brain slices or i
A heavy-duty diesel engine operating case producing no engine-out smoke was studied using combined simultaneous optical diagnostics. The case was close to a typical low-load modern diesel operating point without EGR. Parallels were drawn to the conceptual model by Dec and results from high-pressure combustion vessels. Optical results revealed that no soot was present in the upstream part of the je
In this study, the adsorption of nonionic amphiphiles from aqueous solutions to solid, planar surfaces is investigated using null ellipsometry. This technique allows independent measurements of the amounts adsorbed at the surface and of the mean optical thickness of the adsorbed layer. The time resolution is sufficient for investigating the dynamics of adsorption and desorption in systems of this

Background Autologous haematopoietic stem cell transplantation (HSCT) is a viable option for treatment of aggressive multiple sclerosis (MS). No randomised controlled trial has been performed, and thus, experiences from systematic and sustained follow-up of treated patients constitute important information about safety and efficacy. In this observational study, we describe the characteristics and
Union density remains very high in Sweden. The significantly raised fees for union unemployment funds in January 2007 were followed by an unprecedented decline in the number of union members in modern Swedish history. In the course of two years union density dropped by 6 percentage points: from 77% in 2006 to 71% in 2008. As a result, the density of employers’ associations today is much higher tha
Malmö är en stad som genomsyras av människor och kulturer från olika delar av världen. I den kulturella mångfalden finns tätgrupper med en nära förankring i sin etniska bakgrund. Min uppsats beskriver hur människor med persisk bakgrund förhåller sig till sina persiska musiktraditioner och sin kulturella identitet i det svenska samhället. Studien har inspirerats av mina egna erfarenheter av persiskTo preserve the origin of a musical culture Malmo is a city that contains a lot of people from different parts of the world. There are certain groups with a close bond to their ethnicity. My study is a description of how people with persian roots relates to their persian musical traditions and their cultural identity in the swedish society. The study is inspired by my own experiences of Persian mu
Climate change is progressively advancing, and is affecting the entire globe, with some areas more vulnerable than others. Among them, the sub-Saharan Africa, with a very low adaptive capacity, mainly relies on one economic sector: agriculture. Due to its high climate-dependency, agriculture is at elevated risk. Among the different staple crops produced in the sub-Saharan Africa, maize is the mo
30 Insekter räknade i Lappland under ett halvt sekel I över 50 år har entomologer räknat insekter på fjällsluttningarna kring Ammarnäs i Lappland. Forskarna har, med vissa undantag, funnit att insektsfaunan här håller en långsiktigt stabil nivå. En fråga för kommande års forskning är om frostfjärilen kommer att ta över efter fjällhöstmätaren eller om de två arterna kan leva tillsammans? TEXT: GÖRA

Occupational health and safety management systems are widely used as a systematic approach to managing occupational health and safety in organizations. One important element of which is the development of Standard Operating Procedures to ensure uniform written safety procedures throughout the organization. Such procedures are sometimes restrictive and inadequate to deal with the dynamic and changi
