Abstract A major change in paradigm is taking place in the operation of wastewater treatment plants as automatic process control is becoming feasible. This change is due to a number of different reasons, not least the development of online nutrient sensors, which measure the key parameters in the biological nutrient removal processes, i.e. ammonium, nitrate and phosphate. The thesis is about rea

Popular Abstract in Swedish Enkla kolväten och koldioxid är kemiskt stabila föreningar med mycket låg reaktivitet. På grund av en god råvarutillgång finns ett stort intresse för aktivering och omvandling av dessa föreningar till mer förädlade eller användbara produkter. Reaktioner som bryter starka intramolekylära bindningar är vanligtvis svåra att genomföra på grund av en alltför hög energibarriäAs the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. This thesis describes the synthesis of bis(phosphine) and bis(phosphinite) PCP pincer complexes with

In 2014, more than 200,000 refugees and migrants fled for safety across the Mediterranean Sea. Crammed into overcrowded, unsafe boats, thousands drowned, prompting the Pope to warn that the sea was becoming a mass graveyard. The early months of 2015 saw no respite. In April alone more than 1,300 people drowned. This led to a large public outcry to increase rescue operations. Throughout this period

There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. Regional sediment transport and shoreline evolution models that fully include important coastal processes at local scale are lacking at present. The ov

Popular Abstract in Swedish I och med att mjukvarubaserade produkter ökar i antal ökar också vikten av en effektiv mjukvaruutvecklingsprocess, ur ett konkurrensperspektiv. Bristfällig produktkvalitet och höga utvecklingskostnader är något som mjukvaruutvecklingsorganisationer under många år har kämpat med. Studier inom SPI (software process improvement) syftar till att förbättra produktkvalitet ocThe number of software-based products is increasing, which is why the importance of an efficient software development process is also increasing, from a competitive advantage perspective. For years, software development organizations have been plagued by poor product quality and high development costs. Studies in software process improvement (SPI) have concerned themselves with improving the softw

This paper gives an overview of recently published Swedish guidelines for service-life design of concrete structures. The guideline is based on the probabilistic methodology developed in the European project DuraCrete. The methodology has been further developed and applied to Swedish conditions. The design is based on the definition of several “maintenance classes” where the failure probability is

Det tänkande som ligger under Kristinas självframställning - livet är ett skådespel - beskrivs, samt de genrebundna mönster för Kristinas jag som hon utnyttjar påvisas i Krisinas text, bl a Plutarkos biografi över Alexander den store, den kvinnliga helgonbiografin. Dessa kan knytas till Kristinas manliga klädsel, hennes transvestism samt till hennes bild av sitt offer(abdikationen)som ett hjältedå

Discussion concerning school and cultural change

The films of Swedish filmmaker and writer Carl Henric Svenstedt (b. 1937)are discussed within the framework of the tradition of poetic cinema and documentarism. In focus are four of his later films, Winter Gale (2007), Harg! Platsens musik (2010), Änglastämman (2010), and Tidens gång - Im Lauf der Zeit (2012).

Popular Abstract in Swedish Ett poröst material är ett material med hålrum fyllda av gas eller vätska. Transport av molekyler genom ett poröst material beror på materialets struktur och har betydelse för områden som oljeutvinning, katalytisk avgasrening och blöjors uppsugningsförmåga. Porösa material vars struktur förändras beroende på vattenhalt är svåra att studera eftersom många av de traditioProton nuclear magnetic resonance (NMR) was used to study the self-diffusion of water in porous systems that respond to a change in water content in order to elucidate the porous structure and the properties of the confined water. In the carbohydrate systems cellulose fibers and starch granules, water is free to move throughout the porous objects, albeit with a rate reduced from the value of the
