Catalysts belonging to the Mo-V-Nb-Te-O system have been prepared with both a slurry method and hydrothermal synthesis and were tested for propane and propylene ammoxidation to acrylonitrile. All samples were characterized with BET, XRD, ICP and XPS. The catalysts were found to consist of three phases, to which activity and selectivity correlations were made. The results indicate that both an orth
A short introduction to optimal control problems is presented. For these problems the calculation of sensitivity matrices with the method of adjoint equation is shown. The adjoint equations are derived with the corresponding initial values. At the end two examples are calculated.
This thesis examines the synergies of post-growth policies that aim to decrease environmental pressure at the legislative level of the European Union. Motivated by the urgent need to mitigate global warming and the limitations of the green growth paradigm, this thesis focuses on three specific post-growth policies: restriction of large resource extractions, reduction of caps on pollution, and proh
The project aims to learn about Chinese young people's choices and attitudes towards cooking and solve their problems in cooking. The solution is presented in the form of a product --- a multifunctional electrothermal cooking appliance. The traditional Chinese saying "Food is god for the people" shows the importance of diet in Chinese life. But today, more and more Chinese young peo
In recent years, concerns about the damaging environmental effects of conventional plastics have surged, by which biobased and biodegradable plastics have been promoted as a favour-able alternative. Agricultural side streams have been proposed as a potential feedstock for extracting components for new compostable polymers. The present study investigates agri-cultural side streams for raw material
What happens when open, informal spaces disappear – and specifically, what happens when these spaces disappear in a city that used to be full of them? My project is rooted in two things. The first is the highly debated ”Amazon Tower” in Friedrichshain, and the polarized urban conditions around it. The second is my love for Berlin. Berlin has always been a city in flux. However, the latest round
ODIN (Optical and Diffraction Imaging with Neutrons) is a general purpose imaging in- strument under construction at the European Spallation Source (ESS). The instrument will provide the scientific community with a wide array of neutron imaging techniques, including neutron tomography. Coupled with an integrated X-ray source, the instrument will feature multi-modal capabilities. The complementary
Popular Abstract in Swedish Ökad förståelse för hjärtats pumpfunktion är av stort intresse för att kunna förbättra diagnostik, behandling och prognoser för hjärtsjuka patienter. Blodflöde i hjärtat är direkt kopplat till hjärtats form och rörelse och kan därför vara en viktig markör för hjärtats funktion. Därför var målet med denna avhandling att utveckla och förbättra mätningar av blodflöde med hIncreased understanding of the pumping mechanics of the heart are of great importance to develop diagnostics, treatment and prognostics for cardiovascular diseases. Blood flow in the heart is connected to its anatomy and function, and may therefore be a sensitive marker of cardiac health and disease. Therefore, the aim of this thesis is to develop and validate methods for quantification and visual
Magnetic resonance spectroscopy (MRS) is a non-invasive technique that can be used to detect and quantify multiple metabolites. This chapter will review some of the applications of MRS to the study of brain functions. Typically, (1)H-MRS can detect metabolites reflecting neuronal density and integrity, markers of energy metabolism or inflammation, as well as neurotransmitters. The complexity of th
The mobilization of water has been key for the reconfiguration and modernization of the Spanish state. During the Francoist dictatorship (1939–1975), the hydro-social reengineering of Spain was central to Franco's political mission but failed to provide for subnational, regionalist aspirations which subsequently pursued their own agendas for water development. In this paper we examine the (failed)
Our research aims to develop an intelligent control system for optimizing the operation of lighting systems for a jogging track in the countryside by using adaptive control methods, and optimization of built-in lighting control. Through this, lighting systems will be optimized, energy consumption will be minimized and the lighting system will be adapted to be able to handle a larger amount of loca
Microplastics are increasingly recognized as a pervasive pollutant in both aquatic and terrestrial environments, raising pressing concerns about their ecological impacts and implications for human health. Traditional detection and quantification methods—including manual microscopy and standalone spectroscopic techniques—offer reliable accuracy but are limited by labor-intensive procedures and low
Rocky planets may acquire a primordial atmosphere by the outgassing of volatiles from their magma ocean. The distribution of O between H2O, CO, and CO2 in chemical equilibrium subsequently changes significantly with decreasing temperature. We consider here two chemical models: one where CH4 and NH3 are assumed to be irrevocably destroyed by photolysis and second where these molecules persist. In t
Diet has a pivotal role in shaping the composition, function and diversity of the gut microbiome, with various diets having a profound impact on the stability, functionality and diversity of the microbial community within our gut. Understanding the profound impact of varied diets on the microbiome is crucial, as it will enable us not only to make well-informed dietary decisions for better metaboli
BACKGROUND: Self-reported mental stress is not consistently recognized as a risk factor for stroke. This prompted development of a novel algorithm for stress-phenotype indices to quantify chronic stress prevalence in relation to a modified stroke risk score in a South African cohort. The algorithm is based on biomarkers adrenocorticotrophic hormone, high-density lipoprotein cholesterol, high-sensi
Metachromatic leukodystrophy (MLD) is a fatal, progressive neurodegenerative disorder caused by biallelic pathogenic mutations in the ARSA (Arylsulfatase A) gene. With the advent of presymptomatic diagnosis and the availability of therapies with a narrow window for intervention, it is critical to define a standardized approach to diagnosis, presymptomatic monitoring, and clinical care. To meet the
We know little about how genetic risk factors for two disorders jointly act and interact in predisposing to illness. Therefore, in the Swedish population, born 1970–1990 (n = 2,116,082) and followed through 2015, we examine, using additive Cox models, the impact of the family genetic risk scores (FGRS) for alcohol use disorder (AUD) and major depression (MD), their interaction with each other and
The 2030 Agenda of the United Nations comprises 17 Sustainable Development Goals (SDGs) and 169 sub-targets which serve as a global reference point for the transition to sustainability. The agenda acknowledges that different issues such as poverty, hunger, health, education, gender equality, environmental degradation, among others, are intertwined and can therefore only be addressed together. Impl
