How does parental social status affects child status attainment across time? Social mobility studies have traditionally studied parent-child associations using one ‘dominant’ parent to reflect social origin. However, the institutions of family and work have changed substantially over the past 150 years, in Sweden as elsewhere. These changes are associated with changes in intergenerationalstatus mo
Recent advances in materials science coupled with advanced manufacturing techniques have opened up new possibilities for generating sophisticated models of lung and airways containing cells. These models can be used for studying normal tissue homeostasis as well as for modeling lung development, disease, and regeneration. Three-dimensional (3D) printing has emerged as a leading advanced manufactur
Bygg- och fastighetsbranschen utgör i dagsläget en betydande andel av Sveriges naturresursutvinning samt klimatpåverkan, där påverkan från traditionella stommar av betong och stål länge har dominerat. Klimatintensiva processer såsom cement- och stålproduktion är bidragande faktorer till att branschen är i behov av en hållbar och cirkulär omställning. Återbruk och cirkulärt byggande erbjuder hållbaToday, the construction and real estate industry accounts for a sizable portion of the market´s material consumption and climate impact, with traditional structural materials such as concrete and steel long dominated. Processes such as cement and steel production contribute to the industry´s need for a sustainable transition and circular transition. Reuse and circular construction offer sustainabl
Groundwater, as a vital water resource in arid and semi-arid regions, plays a crucial role in sustaining human livelihoods, agriculture, and industry. Over recent decades, these areas have witnessed rapid groundwater depletion, raising concerns about resource sustainability. This research provides a comprehensive analysis of the factors contributing to the decline in groundwater levels (GWL) withi
Accurate prediction of groundwater levels (GWL) is essential for effective and sustainable water resource management, particularly in arid and semiarid regions where excessive extraction and climate change significantly accelerate aquifer depletion. The nonstationary characteristics of groundwater data pose significant challenges to the performance and reliability of conventional machine learning
We consider thermal fluid structure interaction with a partitioned approach, where typically, a finite volume and a finite element code would be coupled. As a model problem, we consider two coupled Poisson problems with heat conductivities $$\lambda _1$$, $$\lambda _2$$ in one dimension on intervals of length $$l:1$$ and $$l:2$$. Hereby, we consider linear discretizations on arbitrary meshes, such
Popular Abstract in Swedish Olyckor i järnvägssektorn kan ge upphov till katastrofala konsekvenser. I första hand kan människors liv och hälsa drabbas, men allvarliga konsekvenser kan även uppstå för samhället i stort. Detta beror på att järnvägssystemet, liksom en rad andra infrastruktursystem är väsentliga för att vårt moderna samhälle ska fungera. Under de senaste decennierna har dessa system bIn recent decades, the Swedish railway system has faced substantial deregulations. As a result, management of risk is often carried out in settings involving multiple stakeholders having various roles, mandates, and viewpoints on risk, and where no single stakeholder has the superior authority. In order to manage risks in this type of multi-actor setting, the traditional elements of risk assessmen
Målet med projektet var att analysera problem med arbete i kyla i mjölkproduktionsanläggningar vad gäller förekomst, frekvens och skaderisk samt att föreslå åtgärder för förbättringar. Projektet bestod av två delar: Del 1. En fältstudie, som genomfördes dels i Uppsalatrakten, dels i Västerbottens län. Del 2. En enkätstudie, riktad till Lantbrukshälsans medlemmar i norra regionen. Fältstudierna omfThe aim of the project was to analyse problems with cold when working in dairyfarms with respect to prevalence, frequency and risk for injuries and to propose measures for improvements of thermal conditions. The project comprised two parts: a field study and a questionnaire survey. The field studies were performed at seven dairy-farms in the Uppsala region and six dairy-farms in the northern regio
Popular Abstract in Swedish Mer än 75 % av energianvändningen i världen kommer idag från förbränning av fossila bränslen, biobränslen och avfall. Trots att alternativa energikällor är på framfart kommer förbränning stå för den största andelen av världens energianvändning även de kommande decennierna. Tyvärr medför förbränning flera negativa konsekvenser, såsom ökad koldioxidhalt i atmosfären och uLaser-induced incandescence, LII, is a laser-diagnostic technique that can be used to measure the volume fraction and the sizes of soot particles suspended in a gas, such as within a combustion process or in its exhausts. The technique is based on the facts that the time-decay of the radiation from laser-heated soot particles is directly related to the particle size in the probed volume, and that
Popular Abstract in Swedish Bioprocesser är samlingsnamnet på alla de system där man utnyttjar någon biologiskt aktiv komponent (biokatalysator) för att utföra (katalysera) en bestämd reaktion. I den här avhandlingen används ordet bioprocess för mikrobiologiska odlingsprocesser, och biokatalysatorn är då en mikroorganism. Man kan utnyttja mikroorganismer för att producera t.ex. enzymer (för miljövThe control of cultivation conditions and its influence on growth and production have been investigated. The use of fed-batch processes have been demonstrated for several cultivation systems and so has the use of different control signals in these systems. Fed-batch cultivation of Pseudomonas cepacia with on-line measurement and control of the growth rate limiting (toxic) substrate, sodium-salicy
Popular Abstract in Swedish Solenergi kommer att vara en av de viktigaste miljövänliga energikällorna i framtiden, vilket innebär ökat antal solpaneler (för el och värme) som integreras i våra hus men också som fristående produktionsanläggningar. När man planerar framtida hus och stadsdelar är det viktigt att skapa de bästa förutsättningarna för solenergi eftersom hus och stadsdelar finns kvar i fEnergy use in buildings accounts for a significant proportion of the total energy use in many countries. While past and current buildings have solely been energy consumers, future buildings will, besides using less energy, also need to produce (part of ) the required energy on site with renewables. Solar energy is generally very suitable for producing this on-site renewable energy. Although solar
This thesis considers methods for synthesis of linear quadratic controllers for large-scale, interconnected systems. Conventional methods that solve the linear quadratic control problem are only applicable to systems with moderate size, due to the rapid increase in both computational time and memory requirements as the system size increases. The methods presented in this thesis show a much slower
The Euro50 is an astronomical extremely large telescope for optical and infrared wavelength with a 50 m primary mirror. The telescope will have an elaborate control system ("live optics") to correct for atmospheric and telescope aberrations. To study and predict performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the con

I review formation channels for blue stragglers. I consider how they may be produced via collisions between two single main-sequence stars, or via collisions during encounters involving binary stars. Further, I discuss how blue stragglers may be produced via the evolution of isolated binaries. Observations of globular clusters suggest that both mechanisms are contributing.

BACKGROUND: The ubiquitously expressed dipeptidyl peptidase 3 (DPP3) is involved in protein metabolism, blood pressure regulation, and pain modulation. These diverse functions of DPP3 are attributed to the degradation of bioactive peptides like angiotensin II. However, because of limitations in currently available assays for determination of active DPP3 in plasma, the exact physiological function
