Interseriality and Different Sorts of Walking: Suggestions for a Relational Approach to Urban Walking

In this article, we attempt to develop a meta-language for a relational approach to urban walking that is able to account for walking as a mutable, embodied, materially heterogeneous and distributed activity. Following the perspective on walking as developed in a series of articles by Jennie Middleton, we develop a notion of the walker as a socio-technical assemblage. By recognising walking as an

Chitosan flocculation: An effective method for immobilization of E. coli for biocatalytic processes.

Immobilization of Escherichia coli cells containing a ω-transaminase was carried out by flocculation with chitosan and the preparation was used in asymmetric synthesis of (S)-4'-cyano-α-methylbenzylamine, recycled in five consecutive batches. Chitosans with different molecular weights and degrees of acetylation were compared and effects of varying the chitosan properties, cell concentration and ra

The impact of learning on sexual selection and speciation.

Learning is widespread in nature, occurring in most animal taxa and in several different ecological contexts and, thus, might play a key role in evolutionary processes. Here, we review the accumulating empirical evidence for the involvement of learning in mate choice and the consequences for sexual selection and reproductive isolation. We distinguish two broad categories: learned mate preferences

The Inside-Out Amyloid Hypothesis and Synapse Pathology in Alzheimer's Disease.

Cumulative evidence in brains and cultured neurons of Alzheimer's disease (AD) transgenic mouse models, as well as in human postmortem AD brains, highlights that age-related increases in β-amyloid peptide (Aβ), particularly in endosomes near synapses, are involved in early synapse dysfunction. Our immunoelectron microscopy and high-resolution immunofluorescence microscopy studies show that this ea

Full Spectrum of Psychiatric Disorders Related to Foreign Migration A Danish Population-Based Cohort Study

Importance: Although increased risk for schizophrenia among immigrants is well established, knowledge of the broader spectrum of psychiatric disorders associated with a foreign migration background is lacking. Objective: To examine the full range of psychiatric disorders associated with any type of foreign migration background among persons residing in Denmark, including foreign-born adoptees, fir

Comparison of architectures and robustness of model reference adaptive controllers and L-1 adaptive controllers

The paper compares direct and indirect model reference adaptive controllers (MRAC) with the L-1 adaptive controller. The architectures of the closed-loop systems are first compared in a simple setting that clarifies the similarities and differences of the controllers. The indirect MRAC and the L-1 controller have identical state predictors, but they differ in the computation of the control signal,

Measurement of jet quenching with semi-inclusive hadron-jet distributions in central Pb-Pb collisions at root s(NN)=2.76 TeV

We report the measurement of a new observable of jet quenching in central Pb-Pb collisions at root s(NN) = 2.76 TeV, based on the semi-inclusive rate of charged jets recoiling from a high transverse momentum (high-p T) charged hadron trigger. Jets are measured using collinear-safe jet reconstruction with infrared cutoff for jet constituents of 0.15 GeV, for jet resolution parameters R = 0.2, 0.4 a

Tethering cations to aromatic polymers via flexible spacers to enhance the performance of alkaline fuel cell membranes

Conventional anion-exchange membranes based on aromatic polymers with cationic groups placed in benzylic positions on the polymer backbone normally suffer from poor alkaline stability and limited OH− conductivity. However, recently it has been shown that both the conductivity and alkaline stability of anion-exchange membranes can be significantly enhanced by instead placing the cationic groups on

Weak global sensitivity of cloud condensation nuclei and the aerosol indirect effect to Criegee + SO2 chemistry

H2SO4 vapor is important for the nucleation of atmospheric aerosols and the growth of ultrafine particles to cloud condensation nuclei (CCN) sizes with important roles in the global aerosol budget and hence planetary radiative forcing. Recent studies have found that reactions of stabilized Criegee intermediates (CIs, formed from the ozonolysis of alkenes) with SO2 may be an important source of H2S

A capacitive DNA sensor-based test for simple and sensitive analysis of antibiotic resistance in field setting.

To meet urgent needs for solving serious worldwide drug-resistance problems, a sensitive label-free capacitive sensor developed in our group was investigated as a tool to be applied in the field of antibiotic resistance genotyping, for instance the detection of ampicillin resistance gene (ampR). Proof-of-concept data demonstrated its detection sensitivity of pico-molar without any signal amplifica

Dry deposition of reactive nitrogen to European ecosystems: a comparison of inferential models across the NitroEurope network

Inferential models have long been used to determine pollutant dry deposition to ecosystems from measurements of air concentrations and as part of national and regional atmospheric chemistry and transport models, and yet models still suffer very large uncertainties. An inferential network of 55 sites throughout Europe for atmospheric reactive nitrogen (N-r) was established in 2007, providing ambien

The pH-regulated Antigen 1 of Candida albicans Binds the Human Complement Inhibitor C4b-binding Protein and Mediates Fungal Complement Evasion

Candida albicans binds and utilizes human complement inhibitors, such as C4b-binding protein (C4BP), Factor H, and FHL-1 for immune evasion. Here, we identify Candida pH-regulated antigen 1 (Pra1) as the first fungal C4BP-binding protein. Recombinant Pra1 binds C4BP, as shown by ELISA and isothermal titration calorimetry, and the Pra1-C4BP interaction is ionic in nature. The Pra1 binding domains w

Fibromodulin Regulates Collagen Fibrillogenesis During Peripheral Corneal Development

Fibromodulin regulates collagen fibrillogenesis, but its existence/role(s) in the cornea is controversial. We hypothesize that fibromodulin regulates fibrillogenesis during postnatal development of the anterior eye. Fibromodulin is weakly expressed in the limbus at post-natal day (P) 4, increases and extends into the central cornea at P14, becomes restricted to the limbus at P30, and decreases at

Analgetic effects of non-thermal GSM-1900 radiofrequency electromagnetic fields in the land snail Helix pomatia

Purpose : To investigate whether mobile phone radiation might affect snail nociception, employing radiofrequency (RF) electromagnetic fields (EMF) which, to our knowledge, have hitherto not been studied in a snail model. Exposure to extremely low frequency (ELF) magnetic fields has however been shown to significantly affect nociceptive responses. Materials and methods : In the present study, we ex

The Role of Formal and Informal Insurance Mechanisms for Reducing Urban Disaster Risk: A South-North Comparison

Climate change and disaster pose a serious and growing risk to sustainable urban development planning, with disasters having quadrupled in the last three decades. The extent of the changing climatic conditions, in combination with growing urbanisation, is making both Southern and Northern institutions and associated social security and governance systems increasingly inadequate in dealing with ext
