The main focus of this thesis was to evaluate the possibility of establishing a wastewater treatment model for the main COD removal parts in the water line of Sjölunda Wastewater Treatment Plant (WWTP) located in Malmö, in southern Sweden. The finalised model was used to simulate an increased load of on average 5,000 population equivalents (P.E.) per year due to population growth in Malmö. The aim
Den organiserade brottsligheten har länge plågat samhället och dess moderna tappning kan dateras till slutet av 1800-talet. På grund av sin unika struktur har den organiserade brottsligheten visat sig vara särskilt svårutredd. Den organiserade brottsligheten fortsätter att växa i Sverige samtidigt som polis och åklagaren med tillgängliga medel försöker förhindra dess framfart och expansion. FråganOrganised crime is a type of criminal enterprise that has plagued society for ages, with its modern form dating back to the late 1800’s. Because of its unique structure considering the general sense of criminality, organised crime has proven to be an exceptionally difficult criminal activity to battle. Organised crime continues to grow in Sweden, with both the police and prosecutors trying to use
In an effort to mitigate global climate change, the REDD+ mechanism (an acronym for ‘Reduced Emissions from Deforestation and Forest Degradation plus the role of conservation, sustainable management of forests and enhancement of forest carbon stock’) continues to be put forward as an attractive carbon sequestration and forest conservation tool. The Democratic Republic of the Congo (DRC), hosting m
Problem Until recent years, not enough focus has been placed on assuring the strategic fit of launched projects and multi-project management. Even though the situation is getting better, many companies still do not seem to get their project portfolio management right. At the same time research has shown that businesses that feature a systematic portfolio management process outperform the rest. To
I ett internationellt syndikerat låneförfarande går en grupp banker, under ledning av en så kallad arrangörsbank, ihop för att tillsammans finansiera en låntagares kapitalbehov. Det karaktäristiska för arrangemanget, som kan involvera allt från två till flera hundra långivare och enorma summor pengar, är att samtliga deltagande långivare ingår individuella låneavtal med låntagaren vilka samlas undAn international syndicated loan consists of a collection of two or more separate loans made by individual banks to one borrower, which are governed by a single agreement and subject to the same terms and conditions. The arrangement, which may involve everything from just a few to hundreds of banks and enormous amounts of money, offers many advantages for borrowers since it may allow for a more fl
Dying in older persons precedes often by a prolonged period of frailty and multimorbidity. The global increase in the aged population means more death at an older age and highlights the need to integrate palliative care in elderly care. Knowledge-based palliative care is lacking outside the specialist units, for which reason there is insufficient access to palliative care for older persons. Thus t
All over the world there is a shortage of adequate, affordable housing that enables social integration and sustainability. Many individuals and households have access to housing but live in different kinds of involuntary isolation with respect to age, gender, income, culture and ethnic background. There is a lack of housing forms that can contribute to solving these societal challenges through dif
Alloys and bimetallic systems have shown many advantages in heterogeneous catalysis, but the details of their catalytic functions are not always known. For instance, the atomic details about surface reconstructions under catalytic reaction conditions, or which phases that are high-active or low-active. Furthermore, the model catalysts studied in laboratories often differ a lot from the industrial
Context. The solar vicinity is currently populated by a mix of stars with various chemo-dynamic properties, including stars with a high metallicity compared to the Sun. Dynamical processes such as churning and blurring are expected to relocate such metal-rich stars from the inner Galaxy to the solar region. Aims. We report the identification of a set of old super-metal-rich (+0.15 ≤ [Fe/H] ≤ +0.50
Turbulent heat transfer over rough surfaces is crucial in natural and industrial processes, yet it has received less attention than that of momentum transfer. Recently, research in this field is rapidly growing, driven by advancements in computational methods, the role of surface roughness in meteorology, and the growing use of Additive Manufacturing technologies for energy and thermal management
Packaging serves a lot of purposes, and would be hard to do without. Packaging protects the goods during transport, saves costs, informs about the product, and extends its durability. A transport package is required to be strong and lightweight in order to be cost effective. Furthermore, it should be recycled because of environmental and economical concerns. Corrugated board has all of these featu
Key performance indexes (KPIs) in various forms have always been used in one way or another in the production and processing of raw materials. The need for KPIs was accentuated with the advent of industrialism in the western world. The way and strategy of manufacturing industrial products has been divided into several so-called developmental transformations. Primarily after the depression of the 1
The formation of our Galaxy has long been a rewarding area of research within astronomy. A large part of analysis includes using kinematics to separate the different structures in the Milky Way and also to discover accreted stars. While it is highly useful to understand the motions of populations there are systematic errors that follow, due to the difficulties of getting high quality data for them
Popular Abstract in Swedish Avregleringen av elmarknaden uppmuntrar kraftbolag och oberoende kraftproducenter till att driva sina kraftverksanläggningar på ett marknadsorienterat sätt. För att behålla de ekonomiska marginalerna på plussidan så har de mest populära åtgärderna varit att förbättra elverkningsgraden genom ändringar i hårdvaran samt höja totalverkningsgraden genom till exempel samproduThe deregulation of the electricity market drives utilities and independent power producers to operate heat and power plants as profit centers. In order to keep the economic margins on the credit side, the preferred measures have been to improve the electrical efficiency through changes in the hardware and boost the overall efficiency through e.g. combined heat and power (CHP) generation. The bett
New laws and environmental certifications are being introduced today to reduce the environmental impact of the construction industry. From 2022 onwards, environmental declarations have been required for new buildings with a construction area of more than 100 m2 in order to control the environmental impact of a building. Cement production accounts for a large proportion of carbon dioxide emissi
Popular Abstract in Swedish Immunsystemet skyddar kroppen mot infektion. För att kunna skydda mot infektion krävs att immunsystemet är utrustat med kraftfulla biokemiska motmedel. Ett sådant motmedel är antikroppar. Antikroppar är proteiner som känner igen och specifikt binder till andra molekyler via en s k molekylbindande klyfta. När antikropparna har bundit in till en molekyl på t ex en bakteriPrimary infections and vaccination stimulates the immunesystem to produce memory cells that rapidly respond to reexposure of the same antigen. These memory responses are dependent on an adaptive type of immunity that sustains the reactivity of the immune system by long-lived memory immune cells. From an evolutionary perspective adaptive immunity as such appears to be restricted to jawed vertebrate
With her 1953 debut Anna Rydstedt (1928-1994) immediately became part of a strong tradition of Swedish women poets, a tradition represented by authors such as Karin Boye and Edith Södergran. The debut was a furious attack on those who had thwarted her attempts to become a minister in the Church of Sweden. Rydstedt’s poetry is always existential, both in its content and process. Writing, for her, i
Popular Abstract in Swedish Den svenska grundskolan har under de senaste åren genomgått och genomgår fortfarande en stark utveckling inom ramen för den allmänna decentraliseringen i samhället. Beslut och ansvar läggs allt längre ner i organisationen. De krav som ställdes på en skolledare tillbaka i tiden var i första hand att han skulle vara administratör och den som bevakade att skolans verk-samThe issues of the study are: How do the assistant principals face the work as school leaders? Which demands of competence do the new school leaders face? Which needs of competence development exist for new school leaders? In the school studied the organization of the management was changed from one principal and one director of studies to one principal and six assistant principals. All of these we
Popular Abstract in Swedish Bakgrund Hjärntumör hos barn är en relativt ovanlig sjukdom som drabbar cirka 70 barn i Sverige årligen. Under de senaste 40 åren har överlevnaden i barnhjärntumör ökat avsevärt från under 40 % till över 70 %. Överlevnaden har inte varit utan pris och många barn får kognitiva svårigheter efter behandlingen, t.ex. problem med långsamhet, dåligt minne, bristande uppmärksaBackground: Pediatric Brain Tumor (PBT) survivors suffer from cognitive sequelae, especially within the areas of cognitive tempo, attention, executive function and memory. The cognitive difficulties are often accentuated over the years, but knowledge about the long term trajectory is still scarce. Aim: The aim of this thesis was to examine cognitive sequelae after Pediatric Brain Tumor (PBT); ris
Popular Abstract in Swedish Värk i leder och muskler tillhör de vanligaste orsakerna till långtidssjukskrivningar och förtidspensioneringar. En betydande del av dessa tillstånd är orsakade av belastningsergonomiska faktorer i arbetslivet, och kan således förebyggas. Arbetsrelaterade besvär i nacke, axlar och armar är betydligt vanligare bland kvinnor än bland män. Orsakerna till detta är ofullstänWork-related musculoskeletal disorders are widespread, and are, for unclear reasons, more common among females than in males. Several risk factors have been described; constrained and awkward postures, repetitive and/or force demanding motions, and lack of recovery. The exposure to such risk factors was systematically assessed in 116 male and 206 female fish-processing industry workers. Large diff
