Amelogenin self-assembly is a critical step in enamel matrix organization, supporting the spatial confinement of transient ACP and orchestrating hydroxyapatite nucleation and ordered growth. Studies have demonstrated that amelogenin self-assembles into nanoribbons by forming an amyloid-like structure that matches the cross-β pattern observed in the developing enamel matrix. However, molecular dete
The potential of polarization spectroscopy for the detection of trace constituents in sooting combustion was investigated. It was demonstrated that the directionality of the polarization spectroscopy signal can be exploited to efficiently suppress incoherent interferences, e.g., Rayleigh scattering at soot particles. We also show how polarization spectroscopy compares with laser-induced fluorescen
My thesis is an attempt to give a minimalist account of word formation in Swedish. (See Chomsky (1993) and (1994).) In the main part of my thesis I demonstrate how the proposed system accounts for the central aspects of Swedish word formation. Simple words, compounds, and derivations alike are described as formed by Generalized Transformations, primarily by Merge, but also by Move. From a lexico
Cubozoans, or box jellyfish, differ from all other cnidarians by an active fish-like behaviour and an elaborate sensory apparatus(1,2). Each of the four sides of the animal carries a conspicuous sensory club ( the rhopalium), which has evolved into a bizarre cluster of different eyes(3). Two of the eyes on each rhopalium have long been known to resemble eyes of higher animals, but the function and
In 1986, Thames Television broadcast a series of programmes on British cinema. In one of them, dedicated to the Free Cinema documentary movement of the 1950s, and the new wave of films it triggered in Britain in the 1960s, 70s, and 80s (particularly Anderson’s own), Lindsay Anderson took the opportunity to ridicule the prominent box office and Academy Award success of Chariots of Fire, which premi
The c(5 root 2 x root 2)R45 degrees-Pb/Cu(100) surface phase is investigated by means of angle resolved ultraviolet photoemission and low energy electron diffraction in the temperature range between 300 and 550 K. We identify and characterize a temperature-induced surface phase transition at 440 K from the room temperature e(5 root 2 x root 2) R45 degrees phase to a (root 2 x root 2)R45 degrees st
New interactive information and communication technology (ICT) has opened up new possibilities in the field of distance education. The traditional distance education organisations are challenged by conventional universities who have developed into dual mode institutions using interactive ICT. This challenge from conventional universities may also involve a conceptual challenge - from distribution
We present the monolithic integration and electrical characterization of InAs nanowires (NWs) with the well-defined geometries and positions on Si as a platform for quantum transport studies. Hereby, one-dimensional (1D) ballistic transport with step-like 1D conductance quantization in units of 2e2/h is demonstrated for NWs with the widths between 28 nm and 58 nm and a height of 40 nm. The electri
The X-ray structure of the superantigen staphylococcal enterotoxin H (SEH) has been determined at 1.69 Å resolution. In this paper we present two structures of zinc-free SEH (apoSEH) and one zinc-loaded form of SEH (ZnSEH). SEH exhibits the conventional superantigen (SAg) fold with two characteristic domains. In ZnSEH one zinc ion per SEH molecule is bound to the C-terminal β-sheet in the region i
The interpretation of whether a dated metamorphic zircon generation grew during the prograde, peak or retrograde stage of a metamorphic cycle is critical to geological interpretation. This study documents a case at Herrestad, in the eastern part of the 1±0 Ga Sveconorwegian Province, involving progressive metamorphic recrystallization of gabbro to garnet amphibolite and associated behaviour of Zr-
This thesis was motivated by contradictory results from previous studies on reading describing foreign language learners in upper secondary school. Methods based upon ideas by Palinscar & Brown, Cooper, Beck et al, and Krashen were tested on approximately 200 students studying Spanish in the first two years of upper secondary school in Sweden. The methods used are called reciprocal reading, k
We present a program to compute polarizabilities of nominal one-electron systems using the Lagrange-mesh method (LMM) (Baye, 2015), that was used by Filippin et al., (2018). A semiempirical-core-potential approach is implemented, ultimately solving a Dirac-like equation by diagonalizing the corresponding Hamiltonian matrix. In order to build the core potential, the core orbitals are obtained from
In the autumn of 1993 the subject of free trade in visual media was brought into the public eye as never before, at least within the European Union. The occasion was of course the much publicised near breakdown in the ongoing GATT-negotiations. The crux seemed to be that the US and the EU was unable to come to terms whereas films and television programmes was to be seen as manufactured goods which
Glioblastoma (GBM) is the most common and most aggressive primary brain tumor in adults. Glioma stem like cells (GSC) represent the highest cellular hierarchy in GBM and have a determining role in tumor growth, recurrence and patient prognosis. However, a better definition of GSC subpopulations, especially at the surgical resection margin, is warranted for improved oncological treatment options. T
Tetrodotoxin (TTX) is a marine toxin responsible for many intoxications around the world. Its presence in some pufferfish species and, as recently reported, in shellfish, poses a serious health concern. Although TTX is not routinely monitored, there is a need for fast, sensitive, reliable, and simple methods for its detection and quantification. In this work, we describe the use of an automated pa
Confinement of reactants within nanoscale spaces of low-dimensional materials has been shown to provide reorientation of strained reactants or stabilization of unstable reactants for synthesis of molecules and tuning of chemical reactivity. While few studies have reported chemistry within zero-dimensional pores and one-dimensional nanotubes, organic reactions in confined spaces between two-dimensi
X-ray tomography is a well established technique for investigating three-dimensional bulk structures across scales, from macroscopic samples down to their microscopic constituents. The addition of a temporal dimension through dynamic, time-resolved acquisition results in four-dimensional datasets whose complexity often exceeds the processing capabilities of existing image analysis tools.
