Evaluating lifetime nitrogen use efficiency of dairy cattle: A modelling approach

The increased nitrogen (N) use efficiency in cattle farming is proposed as a key action to improve N management and reduce the environmental impact of cattle farming systems. Most attention has been given to lactating cow nutrition, excluding the elements of fertility, disease, and the non-lactating animals within the herd. Therefore, the aim of the current study was to develop a...

Construction and Validation of the Touch Experiences and Attitudes Questionnaire (TEAQ): A Self-report Measure to Determine Attitudes Toward and Experiences of Positive Touch

Despite growing interest in the beneficial effects of positive touch experiences throughout our lives, and individual differences in how these experiences are perceived, there is not yet available a contemporary self-report measure of touch experiences and attitudes, for which the factor structure has been validated. This article describes four studies carried out during the...

Quantum character varieties and braided module categories

We compute quantum character varieties of arbitrary closed surfaces with boundaries and marked points. These are categorical invariants \(\int _S{\mathcal {A}}\) of a surface S, determined by the choice of a braided tensor category \({\mathcal {A}}\), and computed via factorization homology. We identify the algebraic data governing marked points and boundary components with the...

SiO line emission from C-type shock waves: interstellar jets and outflows

We study the production of SiO in the gas phase of molecular outflows, through the sputtering of Si-bearing material in refractory grain cores, which are taken to be olivine. We calculate also the rotational line spectrum of the SiO. The sputtering is driven by neutral particle impact on charged grains, in steady-state C-type shock waves, at the speed of ambipolar diffusion. The...

H I -rich dwarf galaxies in the Hydra I cluster - I. Photometric and H I data

We present H I, optical and near-infrared photometric data of a sample of H I–selected dwarf galaxy candidates in the Hydra I cluster. This database has been compiled in order to study environmental effects on dwarf galaxies in clusters, in particular the role of interactions between them and either the intracluster-medium or companion galaxies, hitherto studied mainly in massive...

Towards the safe use of modern biotechnology: Report on the 7th International Symposium on the Biosafety of Genetically Modified Organisms held in Beijing (China) October 10-16, 2002

Along with the introduction of genetically modified organisms in the field, both biotechnology companies and academic institutes have conducted biosafety research in order to study the potential ecological impact of the modified organisms. With the growing concerns among various stakeholders, priority has been given to academic research on biosafety-related issues. For instance...

FARGO: A fast eulerian transport algorithm for differentially rotating disks

We present an efficient and simple modification of the standard transport algorithm used in explicit eulerian fixed polar grid codes, aimed at getting rid of the average azimuthal velocity when applying the Courant condition. This results in a much larger timestep than the usual procedure, and it is particularly well-suited to the description of a Keplerian disk where one is...

A UKST survey of blue objects towards the galactic centre – a search for early-type stars

We have begun a search for early-type stars towards the galactic centre which are potentially young objects situated within the inner few kiloparsecs of the disk. U and V (or I) band photographic photometry from the UK Schmidt Telescope has been obtained to identify the bluest candidates in nineteen Schmidt fields (centred close to the galactic centre). We have spectroscopically...

Distribution of vesicle pools in cerebellar parallel fibre terminals after depression of ectopic transmission

At parallel fibre terminals in the cerebellar cortex, glutamate released outside of the active zone can activate AMPA receptors on juxtaposed Bergmann glial cell processes. This process is termed “ectopic” release, and allows for directed transmission to astroglial cells that is functionally independent of synaptic transmission to postsynaptic Purkinje neurons. The location of...

Environmental Justice as Scalar Parity: Lessons From Nuclear Waste Management

The development of major infrastructure projects, such as power stations, waste facilities or transport networks, commonly raises concerns of how to ensure environmental justice within policy and planning. Environmental justice has been divergently theorised, though procedural/participative, distributive and recognition-related elements are commonly cited. With growing inter...

Losing cichlid fish biodiversity: genetic and morphological homogenization of tilapia following colonization by introduced species

Among the many negative impacts of invasive species, hybridization with indigenous species has increasingly become recognized as a major issue. However, relatively few studies have characterized the phenotypic outcomes of hybridization following biological invasions. Here we investigate the genetic and morphological consequences of stocking invasive tilapia species in two water...

No evidence that facial width-to-height ratio (fWHR) is associated with women's sexual desire

Facial width-to-height ratio (fWHR) has been linked to many different behavioral tendencies. However, not all of these correlations have replicated well across samples. Arnocky et al. (in press, Archives of Sexual Behavior) recently reported that sexual desire was correlated with fWHR. The current study aimed to test this relationship in a large sample of women. fWHR was measured...

A standardized protocol for quantification of saccadic eye movements: DEMoNS

Objective Quantitative saccadic testing is a non-invasive method of evaluating the neural networks involved in the control of eye movements. The aim of this study is to provide a standardized and reproducible protocol for infrared oculography measurements of eye movements and analysis, which can be applied for various diseases in a multicenter setting. Methods Development of a...
