Art and the evolvement of culture. The altering capacity of institutional critique

Creativity is a principal force of cognitive and communicational genesis that causes alteration of established rules and concepts (Heine/Kuteva 2007) and transgression of cultural borders (Lotman 1990). Artistic activity is normally taken for granted as creative, despite the fact that much artistic intention, is not necessarily aspiring to make any radical change of the circumstances in which it i

Plasticity and the emancipatory architectonics of mutual wholeness and destruction.

The emancipatory appropriation of space, in the sense making personal adjustments and manoeuvres in order to raise a sense of space, can be understood in terms of giving and taking form, or what Catherine Malabou calls “plasticity”. Spatial production is in this sense defined relationally and cannot be fully provided by programmed architectural functions. That kind of relational and emancipatory vThe emancipatory appropriation of space, in the sense making personal adjustments and manoeuvres in order to raise a sense of space, can be understood in terms of giving and taking form, or what Catherine Malabou calls “plasticity”.

Second-Order Multipole Formulas for Thermal Resistance of Single U-tube Borehole Heat Exchangers

The borehole thermal resistance is both an important design parameter and a key performance characteristic of a borehole heat exchanger. Another quantity that is particularly important for deep borehole heat exchangers is the internal thermal resistance between the upward-flowing and downward-flowing fluid channels in the borehole. The multipole method is a well-known and robust method to compute

UVB irradiation induces rapid changes in galanin, substance P and c-fos immunoreactivity in rat dorsal root ganglia and spinal cord

Recent studies have shown that UVB irradiation induces primary and secondary hyperalgesia in rats and humans peaking about 24 h after UVB exposure. In the present study we investigated the changes in galanin, substance P and c-fos immunoreactivity in rat DRG and spinal cord at the L5 level 2–96 h after UVB irradiation. UVB irradiation of the heel area in rats almost increased the skin blood flow t

Protein-based strategies to identify and isolate bacterial virulence factors

Protein–protein interactions play important roles in bacterial pathogenesis. Surface-bound or secreted bacterial proteins are key in mediating bacterial virulence. Thus, these factors are of high importance to study in order to elucidate the molecular mechanisms behind bacterial pathogenesis. Here, we present a protein-based strategy that can be used to identify and isolate bacterial proteins of i

Molecular Mechanisms of L-DOPA-Induced Dyskinesia

The dopamine (DA) precursor, 3,4-dihydroxyphenyl-L-alanine (L-DOPA), is the most effective treatment for Parkinson's disease (PD), but causes dyskinesias (abnormal involuntary movements) in the vast majority of patients. There is a wide consensus that L-DOPA-induced dyskinesia (LID) depends on both pre- and postsynaptic disturbances of the nigrostriatal DA transmission. Presynaptically, LID is ass

Pressurized Hot Water Extraction of Bioactives

The purpose of this book chapter is to give the reader a thorough background to the fundamentals and applications of pressurized hot water extraction (PHWE) for the analysis of bioactive compounds. The chapter summarizes the field for 2009-2014 and includes fundamentals of water as a solvent; equipment; method optimization; a few selected applications; hyphenations and future aspects. It is highli

Long-term agricultural fertilization alters arbuscular mycorrhizal fungal community composition and barley (Hordeum vulgare) mycorrhizal carbon and phosphorus exchange

Agricultural fertilization significantly affects arbuscular mycorrhizal fungal (AMF) community composition. However, the functional implications of community shifts are unknown, limiting understanding of the role of AMF in agriculture. We assessed AMF community composition at four sites managed under the same nitrogen (N) and phosphorus (P) fertilizer regimes for 55 yr. We also established a glass

Evaluating the influences of mixing strategies on the Biochemical Methane Potential test

Mixing plays an important role in the Biochemical Methane Potential (BMP) test, but only limited efforts have been put into it. In this study, various mixing strategies were applied to evaluate the influences on the BMP test, i.e., no mixing, shaking in water bath, shake manually once per day (SKM), automated unidirectional and bidirectional mixing. The results show that the effects of mixing are

Cross section asymmetry of two-body carbon disintegration 12C(γ,p)11B with polarized photons at energy 40–50 MeV

The cross section asymmetry of C12(γ,p01)B11 and C12(γ,p2−6)B11 reactions has been studied at the energy range 40–55 MeV, using linearly polarized tagged photons of the MAX-lab facility. The asymmetry of the C12(γ,p01)B11 processes, which assume the one-body mechanism of the reaction, is Σ≈0.82±0.05 for photon energies 45–50 MeV. The asymmetry for the C12(γ,p2−6)B11 reactions, which produce a maxi

Source separation sewage systems as a trend in urban wastewater management : Drivers for the implementation of pilot areas in Northern Europe

Urban source separation infrastructure systems have a promising potential for a more sustainable management of household food waste and wastewaters. A renewed trend of larger implementations of pilot areas with such systems is currently emerging in Northern Europe. This study investigates the drivers behind the decision of stakeholders to implement source separation systems as well as the importan

Multiscale directed self-assembly of composite microgels in complex electric fields

This study explored the application of localized electric fields for reversible directed self-assembly of colloidal particles in 3 dimensions. Electric field microgradients, arising from the use of micro-patterned electrodes, were utilized to direct the localization and self-assembly of polarizable (charged) particles resulting from a combination of dielectrophoretic and multipolar forces.
