Popular Abstract in Swedish Moderna tillverkningsmaskiner är dyra och därför måste dess tillgänglighet och effektivitet ständigt hållas högt. Sådana resultat kan man inte åstadkomma utan tillämpning av en effektiv underhållsstrategi. Förutsättningar för att minska eller arrestera förslitnings hastighet på maskins delar och öka maskinlivslängden är stora vid användning av tillståndsövervakning, (TÖModern machinery is expensive and therefore must run at high availability and effectiveness which cannot be achieved without an effective maintenance policy. Condition monitoring, (CM), techniques can be utilised to reduce or arrest the rate of deterioration of a component so increasing operating life. The main result reported in this thesis is that the rolling element bearing’s mean effective li

Aluminum interacts with negatively charged surfaces in plant roots, causing inhibition of growth and nutrient uptake in plants growing on acid soils. Pectins in the root cell wall form the major cation adsorption surface, with Ca2+ as the main adsorbing cation. Adsorption of Al3+ and Ca2+ to isolated cell wall material of tomato (Lycopersicon esculentum L.) roots was examined at pH 3.00-4.25 and i

The effect on intestinal macromolecular absorption capacity and immunoglobulin G (IgG) transfer of feeding sow colostrum at different intervals and in different quantities to newborn pigs was studied. An amount of 15 ml/kg body weight (BW) colostrum was fed at 3 (treatment 3-15), 6 (treatment 6-15) or 12 (treatment 12-15) h intervals, respectively, starting 0-4 h after birth for 24 h; or 30 ml/kg

Specific granule protein of 28 kDa (SGP28), also termed cysteine-rich secretory protein 3 (CRISP-3), is a glycoprotein that belongs to a family of cysteine-rich secretory proteins (CRISPs). SGP28 was originally discovered in human neutrophils, but transcripts are widely distributed in exocrine glands (salivary glands, pancreas, and prostate) and also found at lower levels in epididymis, ovary, thy

Förenta Nationernas fredsbevarande operationer har under nästan två decennier besvärats av anklagelser om sexuellt utnyttjande av och sexuella övergrepp på civilbefolkningar. Flera rapporter visar inte bara att organisationens fredsbevarande styrkor begår dessa brott mot just de människor de fått i uppdrag att beskydda, utan också att de undgår ansvar och straff. Denna uppsats undersöker och utvärUnited Nations peacekeeping operations have, for the better part of two decades, been plagued by allegations of sexual exploitation and abuse of local civilian populations. Several reports indicate not only that peacekeepers exploit and abuse the very people they were sent to protect, but also that these crimes routinely go unpunished. This thesis examines and evaluates the different methods of ho

Due to the focus of their study program, environmental and sustainability students are vulnerable to experience negative emotional impacts, potentially affecting their mental health. This thesis contributes to increased understanding of emotions and emotional resilience in relation to the climate crisis by examining experienced emotions, studying the power students have over their emotions, and po

As the need to adapt to a changing climate and the political rhetoric in this regard are growing, Berlin’s Senate has issued strategic policies – complemented by an increase of funding. Berlin’s socio-cultural features and place-based factors seem predisposed for so-called “Nature-based Solutions” (NbS) that can support the achievement of adaptation efforts. This encouraging context seems to be co

Climate change is the greatest challenge of our time. Despite efforts to reduce greenhouse gas (GHG), the emissions contribution from global aviation is set to increase. Electric aviation has emerged as an alternative which could form part of the solution. Sweden, which is on the path to carbon neutrality and has a long history in aviation, could contribute to the global efforts in mitigating clim

Smart City is a paradigm for the development of urban spaces through the implementation of state-of-the-art ICT. There are two main approaches when developing Smart Cities: top-down and bottom-up. Based on the bottom-up approach, the concepts of Smart People and Smart Communities have emerged as dimensions of the Smart City, advocating for the engagement of citizens in Smart People initiatives. Th

Mycoplasma bovis (M. bovis) infections are difficult to diagnose and treat, causing severe economic losses to farms with infected cows. Eurofins Milk Testing Sweden AB screens cow’s milk using qPCR (quantitative Polymerase Chain Reaction) to detect M. bovis infections. Five performance characteristics were chosen to evaluate if ELISA (Enzyme-Linked Immunosorbent Assay) could replace the current sc

Simulations of large detectors such as the ATLAS detector at the LHC (Large Hadron Collider) are compute-intensive projects, and are according to current internal estimates expected to be consuming 40 % of the total ATLAS CPU resources in 2020, creating a need for software optimization strategies. We investigate build configurations of the Geant4 simulation software to find if a) a performance imp

Methylation of lysine (Kme) is known to regulate several important functions, altering gene expression and cell cycle progression. However, mass spectrometry based proteomic analysis of the modification has not been possible due to the lack of efficient purification strategies to enrich modified peptides for analysis. In this study, we identified and evaluated several in-house and commercial candi

Histomorphometry is commonly applied to study bone remodeling. Histological definitions of cortical bone boundaries have not been consistent. In this study, new criteria for specific definition of the transitional zone between the cortical and cancellous bone in the femoral neck were developed. The intra- and inter-observer reproducibility of this method was determined by quantitative histomorphom

This review describes the use of Pickering emulsions for topical drug delivery. The focus is on Pickering emulsions and how to formulate these. However, a short description of the challenges of topical drug delivery is also given. The article describes how Pickering emulsions might have other properties than traditional topical creams. It is our believe that Pickering emulsions could give added va

Tri-isopropylsilyl thio-glycosides (TIPS S-glycosides) were synthesized through base promoted SN2 substitution of glycosyl halides with TIPS-SH or by Lewis acid promoted glycosylation of TIPS-SH with glycosyl acetates or p-methoxyphenyl glycosides. Various thioglycoside derivatives were obtained in high yields by one-pot fluoride-mediated de-silylation and thiol alkylation with alkyl halides or Mi

In this study, different flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenases (FADGDHs) were characterized electrochemically after "wiring" them with an osmium redox polymer [Os(4,4'-dimethyl-2,2'-bipyridine)(2)(PVI)(10)Cl](+) on graphite electrodes. One tested FADGDH was that recently discovered in Glomerella cingulata (GcGDH), another was the recombinant form expressed in Pichia pa

With diversified requirements and varying manufacturing environments, the optimal production planning for a steelmill becomes more flexible and complicated. The flexibility provides operators with auxiliary requirements through an implementable integrated production planning. In this paper, a mixed-integer nonlinear programming (MINLP) model is proposed for the optimal planning that incorporates v

An efficient protocol has been developed for the exo-mono and exo,exo-bis functionalization of Tröger's base in the benzylic 6 and 12 positions of the diazocine ring. The lithiation of Tröger's base using s-BuLi/TMEDA followed by electrophilic quench affords exo-mono- and exo,exo-bis-substituted derivatives of Tröger's base in good to excellent yields. The variation of the number of equivalents of

When flying through narrow spaces, insects control their position by balancing the magnitude of apparent image motion (optic flow) experienced in each eye and their speed by holding this value about a desired set-point. Previously, it has been shown that when bumblebees encounter sudden changes in the proximity to nearby surfaces - as indicated by a change in the magnitude of optic flow on each si
