The increased human dependence on fossil-based fuels, industrial chemicals, and structural materials has caused a drastic increase in atmospheric CO2 levels during the past 50 years. Consequences of this have been observed in the disruption of terrestrial and aquatic ecosystems. Bioengineering of photosynthetic organisms capable of converting CO2 into biomass and value-added organic molecules prov
På en testuppställning med 5 mikrorektorer, utfördes en serie kinetiska tester. Uppställningen möjliggör matning av variabla koncentrationer av metanol, vatten, dimetoxymetan och CO. Även reaktionstemperatur och tryck in i rektorerna är justerbart. Rektorerna är parallella och matas en i taget, vilket gör att 5 prover kan testas under samma förhållanden utan avbrott. Begränsningar på grund av massA series of kinetic experiments were performed using a custom made 5-micro reactor setup. The setup allows for input of varying concentration of methanol, water, dimethoxymethane and O2, and adjustable reaction temperature, and pressure. The reactors are used in sequence, to allow5 different samples to be tested under the same conditions. The influence of mass and heat transport limitations were c
The subject of study is the emission of Volatile Organic Compounds (VOC) during the drying of wood. Heartwood and sapwood from Scots pine were dried at different temperatures (50, 70 and 90°C) in a laboratory kiln. The sampling method, Solid Phase Microextraction was used to collect the different volatile organic compounds during the drying. The gas chromatograph and mass spectrometer was used to
Neutron crystallography is a powerful method to determine the positions of H atoms in macromolecular structures. However, it is sometimes hard to judge what would constitute a chemically reasonable model, and the geometry of H atoms depends more on the surroundings (for example the formation of hydrogen bonds) than heavy atoms, so that the empirical geometry information for the H atoms used to sup
The identification of a subterranean metallic ore from scattering experiments, conducted on the surface of the ground or in a bore hole, is a classic geophysical problem. In general this problem is not well-posed. However, a priori information about the shape of the target provides enough regularization to make the problem numerically stable. The problem is solved by minimizing the mean-square err

Papillomaviruses (PV) are a remarkably heterogeneous family of small DNA viruses that infect a wide variety of vertebrate species and are etiologically linked with the development of various neoplastic changes of the skin and mucosal epithelia. Based on nucleotide similarity, PVs are hierarchically classified into genera, species and types. Novel human PV (HPV) types are given a unique number only
The genus Mentha is highly valued in pharmaceutical, culinary, and personal care industries due to its rich aromatic and pharmacological traits. However, its complex taxonomy and genetic diversity create challenges for breeding programs focused on aroma and therapeutic qualities. To address these challenges, this study developedand validated a rapid, semi-quantitative metabotyping method to effici
I detta avsnitt blir du uppmuntrad till att vara modig och att lära känna dig själv. Avsnittet handlar också hur du ska tänka om du inte vet vad du vill studera eller jobba med. Dessutom pratar vi om varför utbildning aldrig är bortkastad tid. Välkommen till denna podd, som heter "Från gymnasiet till universitet". Om du tänker söka in på universitet eller högskola för första gången– –och är osäker
The relatively new combustion concept known as partially premixed combustion (PPC) has high efficiency and low emissions. However, there are still challenges when it comes to fully understanding and implementing PPC. Thus a predictive combustion tool was used to gain further insight into the combustion process in late cycle mixing. The modeling tool is a stochastic reactor model (SRM) based on pro
ObjectiveThe progression of joint destruction in rheumatoid arthritis (RA) is determined by genetic factors. Changes in IL4 and IL4R genes have been associated with RA severity, but this finding has not been replicated. This study was undertaken to investigate the association between IL4- and IL4R-tagging single-nucleotide polymorphisms (SNPs) and the progression rate of joint damage in RA in a mu

In this study we describe combustion simulations of a single sector and a fully annular generic multi-burner aero-engine combustor. The objectives are to facilitate the understanding of the flow, mixing and combustion processes to help improve the combustor design and the design process, as well as to show that it is now feasible to perform high-fidelity reacting flow simulations of full annular g
