Wastewater treatment is a worldwide necessity that is even more crucial to countries deprived from abundant fresh water sources or unable to afford advanced and costly processes. With this perspective, this thesis was conducted within an Egyptian-Swedish research collaboration that aimed to develop solar-based (as free renewable energy source available locally) process for hazardous wastewater tre

The present work involves a microcalorimetric characterization of the interactions among macrocyclic compounds and aliphatic molecules in aqueous solution. The macrocyclic compounds used in the study are a-,b- and g-cyclodextrin and 25,26,27,28-tetrahydroxycalix[4]arene-5,11,17,23- tetrasulphonate. The results include enthalpies, entropies, standard Gibb's energies and heat capacities of the inter

This paper is part of a conceptual study of a multiuser OFDM system. In previous reports we have examined requirements for the air interface and presented uncoded performance (in terms of bit error rate) for the uplink of such systems. In this report we adopt the user allocation structure from the previous parts of the study and examine the role of channel coding. We present performance simulation

The chapter is based on the assumption that processes outside awareness play a prominent role in the evolvement of creative ideas. The assumption is elucidated within the frame of percept-genetic theory implying that our perceptual world is constructed by processes from within our subjective self. The reasoning is supported by empirical data.

A new Reynolds stress transport model (RSTM) aimed for engineering applications is proposed with consideration of near-wall turbulence. This model employs the SSG pressure strain term, the ω equation, and the SST model for the shear stresses at the near-wall region (say y+ less than or equal 30). The models are selected based on the following merits: The SSG RSTM model performs well in the fully t

The paper describes a concept for securing the geometry in flexible production based on robot assisted framing. This uses the robot(s) as an active device during change-over between product variants and it is assumed that product variants can be produced in any mixed order. The case under study is cabs for trucks which in traditional production require large and heavy equipment which is above the

The present article will place recent Swedish cinema against the background of the evolving public film policy and support – transnational, national and regional – during the last five decades. Particular emphasis will be put on the period since the mid-1990s. Accordingly, a brief presentation and critical analysis of various important aid bodies like the Swedish Film Institute (SFI), the Nordisk

Popular Abstract in Swedish Hur man undviker att bli trakasserad på flicksländornas vis Tidigare forskningsresultat har visat att hos honor i de flesta djurarter begränsas fortplantningkapacitet av hur mycket tid och energi de kan lägga på sina avkommor. Hos hanar, å andra sidan, begränsas fortplantningskapacitet av hur många honor de kan para sig med. Då kan man dra slutsatsen att hanar ska försThis study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations. I. elegans is a small annual damselfly w
