Embodiment, language and mimesis

The present focus on embodiment in cognitive science undervalues concepts such as convention/norm, representation and consciousness. I argue that these concepts constitute essential properties of language, and this makes it problematic for “embodiment theories” to account for human language and cognition. These difficulties are illustrated by examining a particular, highly influential approach to

Numerical Modelling of Soot Formation in Turbulent Non-Premixed Flames

This thesis describes an extended flamelet approach for modelling of soot formation in turbulent hydrocarbons diffusion flames. Detailed chemical kinetic mechanisms are used to compute species concentrations, temperature, density and soot formation rates as functions of flamelet coordinates in the space of mixture fraction and scalar dissipation rate. An ensemble average based on a presumed probab

Viral capsids: Mechanical characteristics, genome packaging and delivery mechanisms

The main functions of viral capsids are to protect, transport and deliver their genome. The mechanical properties of capsids are supposed to be adapted to these tasks. Bacteriophage capsids also need to withstand the high pressures the DNA is exerting onto it as a result of the DNA packaging and its consequent confinement within the capsid. It is proposed that this pressure helps driving the genom

Systemic betamethasone accelerates functional recovery after a crush injury to rat sciatic nerve

Purpose: The aim of the study was to evaluate the effect of perioperatively systemically administered betamethasone on nerve recovery (within or outside a confined space) after induced nerve crush injury. Materials and Methods: The sciatic nerve of 40 adult Wistar rats was crushed. In half of the animals, the injured nerve was entrapped in a silicone tube to simulate the environment of a closed sp

Superhydrophobic properties of nanostructured–microstructured porous silicon for Improved surface-based bioanalysis

Wettability is a fundamental property of a solid surface, which plays important roles in many industrial applications. The possibility to create well-controlled nonwetting states on silicon surfaces without photolithography-based processing can bring many advantages in the biotechnology and microfluidics areas. In this paper, superhydrophobic properties of macroporous–nanoporous structured silicon

Pseudospectra of semiclassical (pseudo-) differential operators

The pseudo-spectra (or spectral instability) of non-selfadjoint operators is a topic of current interest in applied mathematics. For example, in computational fluid dynamics it affects the study of the stability of laminar flows. In fact, even for the most basic flows, the computations entirely fails to predict what is observed in the experiments. The explanation is that for non-normal operators

Monitoring the European pine sawfly with pheromone traps in maturing Scots pine stands

1 During 1989-93, field studies were conducted in Finland to develop a method based on pheromone traps to monitor and forecast population levels of the European pine sawfly (Neodiprion sertifer Geoffr.) and tree defoliation. 2 Three traps per site were baited with 100 mu g of the N. sertifer sex pheromone, the acetate ester of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol), in maturing pine s

Monte Carlo simulations of polyion-macroion complexes. 2. Polyion length and charge density dependence

The complexation between a polyion and an oppositely charged spherical macroion in the framework of the primitive model has been studied by the use of Monte Carlo simulations. The polyion length, linear charge density, and bare persistence length are varied systematically, while the properties of the macroion are kept constant. The polyion charge to macroion charge ratio is varied between 1/4 and

Studier i svensk språkhistoria 8

Studier i svensk språkhistoria 8 är en rapport från konferensen Svenska språkets historia 8 som avhölls i Lund 21-22 maj 2004. Temat för konferensen var Språkförändring på olika nivåer i språket. Tanken var att fokusera på språkförändringsmekanismer i ett brett perspektiv och på alla språkliga nivåer. I detta syfte hade konferensen fyra plenarföreläsningar; en vardera inom fonologi, lexikon, synta

Associations between cerebral blood-flow measured by single photon emission tomography (SPECT), electro-encephalogram (EEG), behaviour symptoms and neurological soft signs in children with attention-deficit hyperactivity disorder (ADHD)

Twenty-eight children with attention-deficit hyperactivity disorder (ADHD) were examined with SPECT (single photon emission computed tomography). Seven of the children had abnormal distribution of the regional cerebral blood-flow (rCBF) on visual evaluation and 10 had abnormal EEG findings. The only clinical finding that differentiated the group with normal from abnormal rCBF was behaviour symptom

Porphyrin and Tetrabenzoporphyrin Dendrimers: Tunable Membrane-Impermeable Fluorescent pH Nanosensors

The pH dependencies of the UV-vis and fluorescent spectra of new water-soluble dendritic porphyrins and tetrabenzoporphyrins were studied. Because of extended -conjugation and nonplanar distortion, the absorption and the emission bands of tetraaryltetrabenzoporphyrins (Ar4TBP) are red-shifted and do not overlap with those of regular tetraarylporphyrins (Ar4P). When encapsulated inside dendrimers w
