Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. In this thesis, the properties of heavy rainfall in a 73 000 km2 area

Modeling the effects of knots in Structural Timber

The main purpose of the pursued research is to increase knowledge of the effects of knots in structural timber so that characteristics of weaker timber may be determined and applied to improve current grading techniques. In the process, a three-dimensional fiber paradigm was established, which describes variations of local principle material axes in timber containing knots. The adaptability of the

BlueBellMouse. A Tool for Kinetic Model Development

Popular Abstract in Swedish För att kunna simulera de fysikaliska fenomen som pågår i förbränning, krävs även en beskrivning av den kinetik som ingår i förbränningsprocessen. För detta ändamål utvecklas kinetiska modeller. En kinetisk modell är en lista med kemiska reaktioner och reaktionshastighetsparametrar. Modellernas tillämpningsområde begränsas av de valideringsfall och de fysikaliska parameThe simulation of physical phenomena occurring in chemical reactors requires the description of the kinetics involved in the underlying combustion process. Kinetic models are developed for this purpose. A software package, BlueBellMouse, has been developed to facilitate a deeper automatization and ease of simulation, reduction and optimization of kinetic models. A kinetic model is made of a list o

Neuroendocrine pathogenesis in adenocarcinoma of the prostate

BACKGROUND: In the prostate, the importance of sex hormones for its normal development and function is well known. However, it has been proposed that various neuroendocrine (NE) hormones and growth factors may be involved in the pathogenesis of prostatic carcinoma (CaP). Neuroendocrine differentiation appears to be associated with tumour progression and the androgen-independent state, for which th

Synaptic Integration of Hippocampal Neurons Generated in the Adult Brain: Influence of a Pathological Environment

Popular Abstract in Swedish Tidigare trodde man att den vuxna hjärnan inte hade någon förmåga att nybilda nervceller. Detta skulle innebära att nervceller aldrig blev ersatta om de skadades eller dog. Nu vet man däremot att den vuxna hjärnan fortfarande producerar nya nervceller från särskilda moderceller, s.k. stamceller, belägna i åtminstone två områden i hjärnan: subgranulära zonen i hippocamThe adult brain constantly produces new neurons from endogenous neural progenitor cells located in at least two regions, the subgranular zone (SGZ) in dentate gyrus of the hippocampus, and the subventricular zone (SVZ). Major efforts are underway to discover the functional significance of new neurons in the adult brain. Several studies have indicated a relationship exists between newborn hippoca

The Uncertain Dichotomous Choice Model - Some Results

Popular Abstract in Swedish Den s.k. "uncertain dichotomous choice" modellen används för att beskriva gruppbeslut. Modellen består av två komponenter: gruppstruktur och röstsystem. Gruppen utgörs av ett antal personer med ett gemensamt mål. Medlemmarnas uppgift är att välja ett av de två givna alternativen, av vilka det ena är korrekt. Dessa två symmetriska alternativ antas så utformade att det inA probabilistic framework used in studying collective decision making is the uncertain dichotomous choice model. The model is essentially characterized by two components: the organizational structure and the voting process. By organizational structure, we refer to a group composed of members with common objectives and who are tasked to choose one of the two given alternatives, one of which is assu

Key Performance Index for Creating an Integrated and Sustainable Academy - A University with the Ability to Meet Future Needs and Challenges Identified in Society and Industry

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 Ultimate Breakdown Beneath the Surface – Zooplankton Influence on C, N and P Degradation in Diatom Aggregates

In the ocean, carbon export is driven by the biological carbon pump where organic matter is transported from the surface layer to the deep sea. The sinking particulate organic matter is mainly a product of phytoplankton aggregates and faecal pellets from zooplankton & fish, together also known as “marine snow”. Marine snow is continuously being degraded by microbial and zooplankton activities

Turbulent Heat Transfer over roughness : a comprehensive review of theories and turbulent flow structure

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

THE INSULIN-LIKE GROWTH FACTOR 1 (IGF-1) SYSTEM IN THE PRETERM RABBIT PUP : A CHARACTERIZATION OF THE IGF-1 MRNA EXPRESSION IN LIVER, IGF-1 PROTEIN LEVELS IN SERUM AND BRAIN DISTRIBUTION OF IGF-1 RECEPTORS

IGF-1 is an essential regulator of fetal growth and brain development. Preterm birth in the human is followed by a rapid decrease in serum levels of IGF-1 and decreased levels of IGF-1 have been associated with development of severemorbidity. A recent clinical trial indicated that supplementation with IGF-1 prevented development of severe intraventricular hemorrhage (IVH) in extremely preterm infa

Zigenarfrågan : Intervention och romantik

Popular Abstract in Swedish Det finns två etablerade sätt att beskriva zigenarnas historia i Sverige. Historien talar antingen om hur illa myndigheterna burit sig åt mot zigenare, eller så berättar historien om zigenarnas självvalda isolering. Gemensamt för beskrivningarna är påståendet att zigenare alltid varit desamma och uppvisar ett likartat levnadssätt genom historien. I denna avhandling studThis thesis analyses Swedish gypsy policy between 1880 and 1970, as part of a larger sociopolitical project undertaken by the Swedish authorities to promote social order and stability. During this period, the treatment of marginalized groups was shaped by the same visions and objectives as for the population as a whole. Gypsies in Sweden have been subject to the same regulations for as other poor

Förhållandet mellan praxis och teori inom etiken

The main question of this thesis is if a practice is right because it is prescribed by an ethical theory, or if an ethical theory is right because it follows from certain practices? I propose the following definitions to illustrate the main alternatives: (1) if a practice is determined by an ethical theory and the ethical theory is not determined by practice, it is possible to speak of a top-down

Collaborative Housing: A tool for social integration and increased sustainability

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

Growth and Characterization of Tandem-Junction Photovoltaic Nanowires

In order to satisfy the growing energy needs of our planet’s population, and at the same time mitigate global warming, sustainable energy sources such as solar energy are indispensable. In addition to conventional silicon-based solar cells, nanotechnology offers interesting approaches for complementary applications. Multi-junction solar cells based on III–V semiconductors hold today’s world-record

The parents school? Narrative research about parental involvement

Popular Abstract in Swedish Föräldrars involvering i skolan har under de senaste decennierna betonats allt mer i skoldebatten. Länge betraktades skolutbildning som enbart ett samhälleligt ansvar, vilket ofta medförde ett markerat avståndstagande från familjen och föräldrarna. Likt andra samhälleliga servicefunktioner har emellertid också skolan i sitt förhållande till sina användare undergått en fOver the last two decades, educational reforms have stimulated an enormous growth in innovative school thinking, effecting both independent schools and mainstream education. Parents and interest groups, previously excluded from general pedagogic practice and planning, are now faced with new opportunities and responsibilities. Parents “invest” in these newly won options in very different ways. Fail

Basic Testing and Strength Design of Corrugated Board and Containers

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

The Gaia -ESO Survey : Old super-metal-rich visitors from the inner Galaxy

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

Oxidation and Reconstructions of Alloy Model Catalysts : Platinum-Rhodium and Palladium-Gold

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

Rättighetsskyddet vid kvalificerade säkerhetsärenden - En granskning av förenligheten mellan lagen (1991:572) om särskild utlänningskontroll och rättighetsskydden i Europakonventionen och regeringsformen

Tillämpningen av lagen (1991:572) om särskild utlänningskontroll har de senaste åren kraftigt ökat. Lagen avser kvalificerade säkerhetsärenden och möjliggör för Säkerhetspolisen att ta utländska medborgare som bedöms utgöra en fara för rikets säkerhet i förvar i avvaktan på att de utvisas. Eftersom utvisningarna sällan kan verkställas med anledning av risken för omänsklig behandling i mottagandelaThe application of the Act (1991:572) Concerning Special Controls in Respect of Aliens have had a major increase these last few years. The law refers to qualified security cases and enables the Security Police to take foreign citizens who are deemed to pose a danger to national security into custody pending their deportation. As the deportations can seldom be carried out due to the risk of inhuman
