Johnson Matthey Formox är ett företag som designar och säljer fabriker för produktion av kemikalien formaldehyd. Företaget tillverkar även katalysatorer för detta ändamål. För att erbjuda en bra och konkurrenskraftig produkt till sina kunder är företaget måna om att processen skall vara effektiv och framförallt kostnadseffektiv. En del i detta är att kartlägga hur vatten påverkar produktionen av fThis diploma work has been performed in collaboration with Johnson Matthey, a company supplying catalysts and technologies, such as formaldehyde plants and catalysts. The aim of the master thesis project was to investigate if and how water impacts the partial oxidation of methanol to formaldehyde over a FeMo-catalyst. The investigation covers how water affects the selectivity to the main product a

This study describes the chydorid (Branchiopoda, Anomopoda) assemblages from 66 European shallow lakes, and presents data relating the assemblages to lake type and ecological quality. Forty species, out of a total recorded European fauna of 60 species, were found in the study sites. No significant differences were found between chydorid assemblages associated with rock and plant substrata. Pattern

Poor public perception can obstruct a construction project in a damaging way. Knowledge about public opinion should be considered as a relevant area of expertise for project managers and as an essential cost element in the planning and completion of construction projects. A consensual approach to a siting controversy requires informal face-to-face interaction among chosen representatives from all

The bone material from three archaeological occupation phases at Huseby Klev provides the best source of evidence currently available about the subsistence strategies of pioneer settlers in Northern Europe. The results from Huseby Klev indicate that the pioneer settlers initially relied heavily on marine mammals for their sustenance. This subsistence strategy changed during the second and third oc

The active site of the [FeFe] hydrogenases contains two Fe ions bound to one Cys ligand, three CO molecules, two CN(-) ions, and a dithiolate ligand. The nature of the last of these has been much discussed, and it has been suggested that it contains C, N, or O as the bridgehead atom. Most experimental studies indicate a N atom, whereas a recent density functional theory (DFT) study of a crystal st

EG har kontinuerligt ägnat sig åt reglering av kemiska produkter. 1967 antogs första rättsakten som rörde kemikaliekontroll. Under 1960- och 70-talen antogs gemenskapslagstiftning främst för att undanröja hinder för den gemensamma inre marknaden och därmed främja den fria varurörligheten. Under 1980-talet blev miljöskydd ensamt skäl att anta lagstiftning på kemikalieområdet. Genom åren har ett ant

Generalist parasites experience selective pressures from the various host species they infect. However, it is unclear if parasite transmission among host species precludes the establishment of host-specific adaptations and population genetic structure. We assessed the population genetic structure of the vector-transmitted avian haemosporidian parasite Haemoproteus majoris (lineage WW2; n = 34 infe

Bakgrund: I bygg- och anläggningsbranschen skedde 1470 olyckor år 2018 där några även ledde till dödlig utgång (Arbetsmiljöverket, 2018). Utbildningen till maskinförare idag är både lång men grundlig och ger maskinföraren de förutsättningar som krävs för att framföra ett anläggningsfordon på ett säkert sätt på en byggarbetsplats. Genom regleringar från arbetsmiljöverket och förebyggande åtgärder aBackground: In the construction industry a total 1470 accidents occurred 2018 where some of them also led to fatal outcome (Arbetsmiljöverket, 2018). The qualification to be a construction machine operator are both long and thorough and will give the operator the prerequisites to convey the construction machine in a safe way on different construction sites. Through regulations from Arbetsmiljöverk

In silico tools for splicing defect prediction have a key role to assess the impact of variants of uncertain significance. Our aim was to evaluate the performance of a set of commonly used splicing in silico tools comparing the predictions against RNA in vitro results. This was done for natural splice sites of clinically relevant genes in hereditary breast/ovarian cancer (HBOC) and Lynch syndrome.

Hybrid is what we call meetings, seminars or lectures that have both physical and digital participants. It might be the case that a majority of students attend a lecture on site and a few students attend from home – or vice versa. Hybrid teaching has become a relatively common format at University but it comes with several challenges. Therefore, it’s important to think through a meeting in advance

Endogenous programs that regulate annual cycles have been shown for many taxa, including protists, arthropods, fish, mammals and birds. In migration biology, these programs are best known in songbirds. The majority of songbirds rely on a genetic program inherited from their parents that will guide them during their first solo-migration. The phenotypic components of the program are crucial for thei

Fourteen tree-ring chronologies developed from 788 peatland Scots pines sampled at sites in Estonia, Belarus and Sweden were compared for common growth trends and possible links to regional climate dynamics. Several synchronous growth release events were detected, especially during the 1910s, 1930s, and around 1970 and 1990, indicating that hydrological shifts and associated tree growth responses

There are many projects in Mozambique for poverty reduction. One of these projects is funded by Millennium Challenge Account (MCA) and is aimed to install a total of 600 rural water points in the provinces of Nampula and Cabo Delgado. Each water point consists of a drilled well, a water pump and a communal washing basin. Vertical Electrical Sounding (VES) was used for assessing the uitability of

In this thesis, the GW approximation (GWA, Green's function G times screened interaction W) and the Hubbard I approximation (HIA) are combined in a non-self-consistent one-shot calculation to determine the electronic structure of a one-dimensional strongly-correlated model. The scheme was chosen to incorporate both screening effects through the GWA and strong on-site correlations through the a

With their highly sensitive visual systems, the arthropods have evolved a remarkable capacity to orient and navigate at night. Whereas some navigate under the open sky, and take full advantage of the celestial cues available there, others navigate in more difficult conditions, such as through the dense understory of a tropical rainforest. Four major classes of orientation are performed by arthropo

The effect of future changes in temperature and precipitation patterns on arctic ecosystem functioning is often assessed using state-of-the-art ecosystem models. Many models however lack detailed representation of wintertime processes, as pointed out by recent studies (Wang et al. 2016, Slater and Lawrence 2013). This bias may influence the derived outputs, such as soil temperature, permafrost ext

Summary: The Fracture Liaison Service (FLS) Consensus Meeting endorsed by the International Osteoporosis Foundation (IOF), Asian Federation of Osteoporosis Societies (AFOS), and Asia Pacific Osteoporosis Foundation (APOF) was hosted by the Taiwanese Osteoporosis Association on October 14, 2017. International and domestic experts reviewed the 13 Best Practice Framework (BPF) standards and concluded

The study investigates how the Best Interests of the Child principle in the UN Children's Rights Convention (Article 3) has been adapted in custody disputes in Egypt, Sweden, and Uzbekistan. Although the Convention on the Rights of the Child offers a common normative benchmark, divergent legal cultures shape its domestic meaning: Egypt is governed by religious and state legal norms intersecting wi

Pleural and tracheal injuries remain significant problems, and an easy to use, effective pleural or tracheal sealant would be a significant advance. The major challenges are requirements for adherence, high strength and elasticity, dynamic durability, appropriate biodegradability, and lack of cell or systemic toxicity. We designed and evaluated two sealant materials comprised respectively of algin
