This thesis defends a hedonistic theory of value consisting of two main components. Part 1 offers a theory of pleasure. Pleasures are experiences distinguished by a distinct phenomenological quality. This quality is attitudinal in nature: it is the feeling of liking. The pleasure experience is also an object of this attitude: when feeling pleasure, we like what we feel, and part of how it feels is
The Swedish alternative movement’s place-making activities in the seventies have been understood as an attempt to escape the political sphere. In this thesis, I investigate the ideas and practices of societal transformation seen in rural intentional communities and, to a lesser degree, urban sites. Challenging the idea that such intentional communities were solely concerned with the creation of ‘p
Plant cells have two main modes of growth generating anisotropic structures. Diffuse growth where whole cell walls extend in specific directions, guided by anisotropically positioned cellulose fibers, and tip growth, with inhomogeneous addition of new cell wall material at the tip of the structure. Cells are known to regulate these processes via molecular signals and the cytoskeleton. Mechanical s
Cadmium-enrichment of farmland soil greatly threatens the sustainable use of soil resources and the safe cultivation of grain. This review paper briefly introduces the status of farmland soil as well as grain, which are both often polluted by cadmium (Cd) in China, and illustrates the major sources of Cd contaminants in farmland soil. In order to meet soil environmental quality standards and farml
Complexes of the type trans-[PtPhFL2], where L = PPh3 (4), PMe2Ph (5), were synthesized. Complex 4 was characterized by X-ray crystallography. The equilibrium constant for the substitution of the fluoride trans to phenyl in 4 by Cl- and I- was determined, and the stability sequence follows the normal trend seen in "soft" metal centers: i.e., the Pt has a preference for the halide in the order I >
Mycorrhizal symbioses -- the union of roots and soil fungi -- are universal in terrestrial ecosystems and may have been fundamental to land colonization by plants1,2. Boreal, temperate, and montane forests all depend upon ectomycorrhizae1. Identification of the primary factors that regulate symbiotic development and metabolic activity will therefore open the door to understanding the role of 2 ect
We have previously demonstrated intracellular degradation of the heparan sulfate side-chains in recycling glypican-1 by heparanase and by deaminative cleavage at N-unsubstituted glucosamine with nitric oxide derived from intrinsic nitrosothiols [see Ding, K., Mani, K., Cheng, F., Belting, M. and Fransson, L.-. (2002) J. Biol. Chem., 277, xxx-xxx; prepub M203383200]. To determine where and in what
The partly hot-water driven CO2 capture plant offers a significant potential for improvement in performance when implemented in a combined-cycle power plant (CCPP). It is possible to achieve the same performance with a dual-pressure steam cycle as in a triple-pressure unit. Even a single-pressure plant can attain an efficiency competitive with that achievable with a triple-pressure plant without t
Objective: The aims were to evaluate the frequency and nature of errors in medication when patients are transferred between primary and secondary care. Method: Elderly primary health care patients (> 65 years) living in nursing homes or in their own homes with care provided by the community nursing system, had been admitted to one of two hospitals in southern Sweden, one university hospital and on
Popular Abstract in Swedish Den nuvarande teknologin inom förbränningsmotorer har möjligheten att hantera den alltmer strikta myndighetskraven på förbränningsmotorn. Emellertid de nödvändiga tekniska lösningarna som krävs är dyra och alltmer tekniskt krävande.

Popular Abstract in Swedish Denna doktorsavhandling i ämnet pedagogik utgör en analys av effekter av den pågående kulturella globaliseringen genom att granska två internationella magisterprogram vid Lunds universitet. Studiens syfte är att spåra mönster i en bärande pedagogisk idé för överföring av ett interkulturellt tänkande i tvärkulturella möten genom att utforska, beskriva och försöka förstå The present study is designed to analyze the effects of the ongoing cultural globalization. It utilizes as its empirical setting two special programmes called the International Master's Programme (the IMP,) directed by Lund University in Sweden. The aim of the study is to infer a pedagogic idea for intercultural transmission through cross-cultural encounters by exploring, describing, and comprehen
The objective of this thesis is to propose a way to introduce social and cultural aspects of environmental degradation to the sustainable development debate. This is done by a reflexive and critical examination of environmental research as it has been applied to different spatial levels (and thus levels of social complexity). The spatial categories discussed are the city, the household and the lan
This paper presents a front-end architecture for fully integrated 60 GHz phased array receivers. It employs LO-path beamforming using a phase controlled phase-locked loop (PC-PLL). To demonstrate the architecture a circuit is implemented featuring a two stage low noise amplifier, two cascaded active mixers, and a PC-PLL. The receiver downconverts the 60 GHz signal in two steps, using LO signals fr
Cationic liposome-DNA (CL-DNA) complexes, are regarded as promising materials for safe and efficient delivery of genes for therapeutical applications. In order to be used in vivo, these complexes may be coated with a hydrophilic polymer (e.g. polyethylene-glycol, PEG) that provides steric stabilization towards adhesion of proteins and removal by the immune system. In this work we study the influen
A first research development progress report of the Chromosome 19 Consortium with members from Sweden, Norway, Spain, USA, China and India, a part of the Chromosome-Centric Human Proteome Project (C-HPP) global initiative is presented (http://www.c-hpp.org). From the chromosome 19 peptide-targeted library constituting 6159 peptides, a pilot study was conducted using a sub-set with 125 isotope-labe
The calcium-sensitizing Rho A/Rho kinase pathway has been suggested to play a role in the control of nongenital vascular smooth muscle. Rho-associated kinases (ROKs) cause calcium-independent modulation of smooth muscle contraction, and have been demonstrated in the bladder, prostate, and corpus cavernosum. Until now, it is not known whether ROKs and related proteins play a role in the control of
Entrained flow gasification of biomass using the cyclone principle has been proposed in combination with a gas engine as a method for combined heat and power production in small to medium scale (<20 MW). This type of gasifier also has the potential to operate using ash rich fuels since the reactor temperature is lower than the ash melting temperature and the ash can be separated after being collec
Vitreoscilla is an obligate aerobic bacterium found in oxygen-poor environments such as stagnant ponds and decaying vegetable matter. Vitreoscilla induces the production of a homodimeric hemoglobin (VHb) when subjected to oxygen-limiting conditions. It is thought that VHb facilitates oxygen delivery to the respiratory apparatus of its host by increasing the local oxygen concentration under oxygen-
Popular Abstract in English Airborne particulate matter is well known because of its adverse impacts on human health and its role in climate processes. In order to understand completely the role of aerosols in atmosphere, their chemical composition is of basic importance. Chemical analysis of aerosols involves broadly two steps, extraction step and detection/quantification of chemical constituents
