Power supply systems play a very important role in everyday life applications. There are mainly two ways of producing energy for low power generation: electrochemical batteries and small engines. In the last few years, many improvements have been carried out in order to obtain lighter batteries with longer durations but unfortunately the energy density of 1 MJ/kg seems to be an asymptotic value. A

E-business is becoming more and more common today. The predictions of future growth give clear indications that companies will use e-business more and more. However in the growth of e-business it has been identified that there is a common lack of understanding in customer needs and logistics. In order to reduce some of this non-understanding this thesis seeks answers to the following question: - H

There are many different factors that influence our perception of products i.e. personal, product related and external factors. For designers to be able to address them all when creating new products, we need to deepen our understanding of the totality of perceptual experiences from non-instrumental interaction with products. One way of achieving this is by stimulating the creative process by util

This thesis presents the utilization of electroanalytical methods for analysis of dynamic cellular processes such as exocytosis, intracellular redox reactions and cell surface interactions. Microchips have been designed and manufactured with the purpose of monitoring dopamine exocytosis from single or a small ensemble of PC12 cells. The electrode surface was modified with self assembled monolayers

During the last decades of the 1900’s, businesses started to - in a broader sense than before - acknowledge the economic relevance of intangible components, such as emotional experiences, of products and services. This dissertation explores how the so-called lifestyle hotel segment reflects the socio-cultural currents that set the conditions for these changes in the Western economy. The aim of the

Media coverage of the Israeli–Palestinian conflict does not necessarily enhance one’s knowledge or understanding of the Palestinians; on the contrary they are often reduced to either victims or perpetrators. Similarly, while many academic studies devote considerable effort to analyzing the political situation in the occupied territories, there have been few sophisticated case studies of Palestinia

Den här guiden ger lokala politiker och tjänstemän ett processorienterat verktyg för att stärka förankringen (integrationen) av klimatanpassning i relevanta sektorer av kommunal verksamhet, med syftet att främja en hållbar stadsutveckling. Den kan därför ses som ett instrument för att vägleda en integrationsprocess. Guiden presenterar systematiskt de nivåer och områden där förankring av klimatanpaThis guideline offers local government officers and local politicians process-oriented assistance for integrating climate change adaptation within relevant sectors of municipal administration with the aim of fostering sustainable urban development. It is thus an instrument to support leadership of this integration process. The levels and areas where integration of climate change adaptation is rele

A dual-band CMOS front-end was designed and fabricated in a 0.18 μm CMOS process. The front-end employs a common-gate low noise amplifier (LNA) with capacitive cross coupling (CCC) technique and a passive mixer. The band selection is performed by switching a capacitor in and out of the LNA load, changing the resonance frequency between 2.2GHz and 4.0GHz. The measured noise figure is below 3.5dB fo

In the present paper, we have studied particle dissolution and crystal growth of the poorly water soluble drug felodipine, using fluorescence as a probe for the amount of crystalline material. Dissolution kinetics is essentially diffusion-controlled, while the rate of crystal growth is significantly slower compared to the diffusion-controlled limit. The deviation from diffusion control was charact

The extraction procedure for analysis of the raffinose family oligosaccharides (RFOs) in blanched leguminous vine peas was optimized. For this purpose, 25 pea samples from different cultivars and of different maturity were chosen at random. The effect of blanching was also studied in four cultivars. The yield of oligosaccharides was almost double on average when extracted with 50% ethanol as compa

The 1,3-bis[di(4-methoxyphenyl)amino]azulene 1 and 1,3-bis[di(4-methoxyphenyl)amino]azulene-2-carboxylic acid methyl ester 2 were synthesized and investigated by spectroscopic and electrochemical methods in order to estimate the electronic coupling between the attached amine redox centers. We found that the electronic coupling V which is mediated by a nonalternant 1,3-azulene bridge in the radical

The hypotheses were based on conceiving of automatic mimicking as involved in emotio¬nal empathy. Mimicry reactions (EMG) in high- and low-empathy subjects were studied when subjects were exposed to pictures of angry or happy faces. The degree of corre¬sponden¬ce between subjects’ facial EMG reactions and their self-reported feelings was compared. The comparisons were made at different stimulus ex

This paper describes in what ways hierarchical organizations influence the utilization and dissemination of knowledge. Particular attention will be paid to the role that tacit knowledge has. The reporting system of incidents is one element in a larger institutional process, often termed 'lessons learned' (LL). This process helps to suggest solutions to identify shortcomings and facilitates in maki

The combustion and melt dripping of poly(ethylene-co-butyl acrylate) (EBA), EBA blended with polypropylene (EBAePP) and poly (ethylene-co-methacrylic acid) (EMAA), each blended with calcium carbonate and polydimethylsiloxane, were studied. In situ measurement of the temperature gradient in the cone calorimeter were combined with infrared spectroscopy measurements on specimens withdrawn and quenche

We focus on exclusive production of neutral technipion (pi) over tilde (0) in pp collisions at the LHC, i.e. on pp -> pp (pi) over tilde (0) reaction. The dependence of the cross section on parameters of recently proposed vector-like Technicolor model is studied. Characteristic features of the differential distributions are discussed. For not too large technipion masses the diphoton decay channel
