Chitosan was chosen as a natural polymer for dispersion of single walled carbon nanotubes (SWNT) based on its ability to efficiently solubilize SWNTs to form a stable dispersion. Moreover, chitosan films deposited on a surface of a glassy carbon (GC) electrode are mechanically stable. Further stabilisation of the chitosan film containing SWNT (CHIT-SWNT) was done by chemical crosslinking with glut
The consumption of alcohol imposes costs on the society and several cost-of-illness studies have been conducted to estimate these costs. This essay presents the results from five cost-of-illness studies and examines the methodology used. The differences in results are discussed in reference to the differences in the applied methods. The results differ immensely from US$ 91 to US$ 2,433 per capita.
Two approaches based on alkaline hydrolysis, in combination with either stir-bar sorptive extraction (SBSE) or sonication, were developed for the determination of banned azo dyes in bovine leather. All dyes were determined indirectly by measuring their corresponding harmful amines, formed after chemical reduction. Quantification was performed by employing standard addition methodology to compensat
Many of the physiological adaptations evolved in terrestrial invertebrates to resist desiccation have also been shown to enhance the survival of low temperatures. In this study we have examined temporal changes in the physiology of the collembolan Folsomia candida during acclimation to mild desiccation stress (98.2% RH), and how physiological changes correlate with resistance to subsequent cold sh
Popular Abstract in Swedish Förbränning är den viktigaste energikällan på jorden och en ökad förståelse av förbränningsprocesser är väsentlig för att minska miljöfarliga utsläpp och för att öka effektiviteten av förbränningsanläggningar och motorer. För detta ändamål är det viktigt att bestämma bl. a. koncentrationer av ämnen som bildas under förbränningen. Laserbaserade mätmetoder möjliggör berörCombustion is the most important source of energy worldwide. A better understanding of it is essential if pollutant emissions are to be reduced and combustion devices be made more efficient. This requires measurement of physical and chemical combustion parameters. Laser-induced fluorescence (LIF) is widely employed as a laser-diagnostic technique for the detection of combustion species but it suff
A cheap value-added product, the protein fraction of barley spent grains is proposed as a source of a potential and economical cultivation medium. We showed that medium composed of protein fraction extract allows the isolation of actinobacteria, especially Streptomyces, from soil samples, and enhances the sporulation. It was used for the screening and production of the biologically active substanc
Selective dorsal rhizotomy is a surgical procedure with a selective division of posterior spinal nerve rootlets to treat spasticity in children. The extensive surgical procedure with multilevel laminectomies and the nerve root manipulation result in intense pain postoperatively. Two intrathecal (IT) regimes of pain treatment were compared in these children, concerning their pain relief and possibl
The release of two compositionally different solutes from a composite gel composed of two different populations of microgel particles embedded in a single bulk gel matrix is described, showing the potential of the "plum-pudding gel" as a multifunctional platform for controlled surface release. One hydrophobic solute (pyrene) and one hydrophobic and charged solute (rhodamine 123) were chosen as the
OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mo
We analyzed the cumulative revision rate in 1,474 patients (1,660 hips) operated on with a cemented Scan Hip Classic I prosthesis from November 1983 to January 1994 at Lund University Hospital. The revision rate was analyzed for 3 diagnoses--arthrosis, rheumatoid arthritis and complication after a hip fracture--and for 2 head diameters--22 and 32 mm. Until January 1996, 36 hips were revised: 31 be
Collective action can be challenging in the governance of common pool resource. While social learning has the potential to facilitate negotiations and communications, power imbalance can still challenge the common pool resource (CPR) governance. In an attempt to study collective action in that context, I undertook a qualitative case study at the Cañete basin, Peru. The primary data was manly colle
Crimes and violations are constantly committed against human rights all over the world. Whole populations are victims of genocide and ethnic cleansing, while the international society has a commitment and responsibility in their hands to intervene. But what happens when the international society and the United Nations Security Council are unwilling to come to a unanimously decision? This study has
In crisis-hit Greece, there have been an unprecedented rise of grassroots self-help initiatives for the last three to four years, and the whole phenomenon has come to be known as the quest for social and solidarity economy. With the consolidation of political and economic power in today’s capitalist market economy, the social and solidarity movement in Greece has been seeking for a way forward to
This thesis provides an account of the storage strategies for mitigation of excess electricity production (EEP) from wind energy in the Öresund region of Denmark and southern Sweden, characterized by an increasing share of wind power. Hydrogen is a versatile storage technology with potential in both large and small scale options, and for utilization in several application areas. TIS framework and
Denna uppsats fokuserar på offentliga upphandlingar och behandlar begreppet onormalt låga anbud. Dessa anbudens låga nivå kan vara grundade i dolda motiv eller missförstånd från anbudsgivaren. Detta medför att den upphandlande myndigheten kan vilja förkasta det aktuella anbudet. Den låga nivån kan däremot lika gärna vara helt legitimt och bör därmed inte förkastas. Regelverket samt praxis på områdThis thesis focuses on public procurements and deals with the concept of abnormally low tenders. The low levels in a tender can be founded in a hidden agenda or in a misunderstanding by the tenderer. This means that the contracting authority may wish to reject the current offer. The low level, on the other hand, can just as easily be completely legitimate and should therefore not be discouraged. T
Denna uppsats är en beskrivande idéanalys av UNICEF:s rättighetsperspektiv så som det uttrycks i deras strategiska plan för åren 2014-2017. Syftet är att undersöka hur en rättighetsförståelse visas hos UNICEF i jämförelse med det rättighetsbaserade tillvägagångssätt organisationen har åtagit sig att följa. Detta rättighetsbaserade tillvägagångssätt utgör min teori i den första delen av min analys.This essay is a descriptive idea analysis of the rights perspective shown by UNICEF, the United Nations Children’s Fund, in their Strategic Plan for the time period of 2014-2017. The purpose is to examine how an understanding of rights is shown by UNICEF, in accordance with the principles set forth in the human rights-based approach to development that the organization is committed to follow.
