A Comparative Study of the Innate Humoral Immune Response to Avian Influenza Virus in Wild and Domestic Mallards
Domestic mallards (Anas platyrhynchos domesticus) are traditionally used as a model to investigate infection dynamics and immune responses to low pathogenic avian influenza viruses (LPAIVs) in free-living mallards. However, it is unclear whether the immune response of domestic birds reflects the response of their free-living counterparts naturally exposed to these viruses. We investigated the exte
Exploring the potential of the glycerol-3-phosphate dehydrogenase 2 (GPD2) promoter for recombinant gene expression in Saccharomyces cerevisiae
A control point for keeping redox homeostasis in Saccharomyces cerevisiae during fermentative growth is the dynamic regulation of transcription for the glycerol-3-phosphate dehydrogenase 2 (GPD2) gene. In this study, the possibility to steer the activity of the GPD2 promoter was investigated by placing it in strains with different ability to reoxidise NADH, and applying different environmental con

Measurable time is governable time: Exploring temporality and time governance in childcare social work
This article deals with the workings of time governance in welfare professional settings. A contribution is made to current literature by offering insights into how ‘governing by the clock’ works at the micro-level in everyday interaction and why clock time is purposeful for the operation of power in a welfare bureaucratic context. The main argument posited is that measurability and decontextualis
Coping with Chronic Warfare : The Athenian Experience
In Classical Athens, being at war was more common than peace. The military expenditures were correspondingly large. The main puzzle, however, is notfinancial, but where the Athenians found the multitude of rowers needed for their ships. It was not until the end of the Peloponnesian War that there were good reasons to use slaves as rowers. The Spartan occupation of Decelea in 413 BCE had profound eIn Classical Athens, being at war was more common than peace. The military expenditures were correspondingly large.

Ethical Orientation and Research Misconduct Among Business Researchers Under the Condition of Autonomy and Competition
The topics of ethical conduct and governance in academic research in the business field have attracted scientific and public attention. The concern is that research misconduct in organizations such as business schools and universities might result in practitioners, policymakers, and researchers grounding their decisions on biased research results. This study addresses ethical research misconduct b
Time-resolved luminescence spectroscopy of ultrafast emissions in BaGeF6
Phase-pure crystalline micropowder samples of BaGeF6 were prepared and studied under excitation by tuneable synchrotron radiation and 10 keV electron beam. Time-resolved photoluminescence emission and excitation spectra and a set of single emission decay curves were recorded at 7 K for the exciting photon energy region of 4.3–45 eV. Several intrinsic emissions were revealed in BaGeF6 and their ori

Differences in fatty acids composition between Plasmodium infected and uninfected house sparrows along an urbanization gradient
Anthropogenic activities such as intensification of agriculture, animal husbandry and expansion of cities can negatively impact wildlife through its influence on the availability of high-quality food resources and pathogen transmission. The house sparrow (Passer domesticus), an urban exploiter, is undergoing a population decline. Nutritional constrains and infectious diseases has been highlighted
Post-nucleation evolution of the liquid-solid interface in nanowire growth
We study using in situ transmission electron microscopy the birth of GaAs nanowires from liquid Au-Ga catalysts on amorphous substrates. Lattice-resolved observations of the starting stages of growth are reported here for the first time. It reveals how the initial nanostructure evolves into a nanowire growing in a zincblende 111 or the equivalent wurtzite0001 direction. This growth direction(s) is
A rapid sedimentary response to the Paleocene-Eocene Thermal Maximum hydrological change : New data from alluvial units of the Tremp-Graus Basin (Spanish Pyrenees)
A massive emission of light carbon about 56 Ma, recorded in marine and terrestrial sediments by a negative carbon isotope excursion (CIE), caused a short-lived (~170 kyr) global warming event known as the Paleocene–Eocene Thermal Maximum (PETM). The onset and core of this event is represented in the south Pyrenean Tremp-Graus Basin by two successive alluvial units, the Claret Conglomerate (CC) and

RIFM fragrance ingredient safety assessment, phenethyl phenylacetate, CAS Registry Number 102-20-5
The existing information supports the use of this material as described in this safety assessment. Phenethyl phenylacetate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data show that phenethyl phenylacetate is not genotoxic. Data provide a calculated MOE >10
The RIFM approach to evaluating Natural Complex Substances (NCS)
The Research Institute for Fragrance Materials, Inc. (RIFM) has evaluated safety data for fragrance materials for 55 years. The safety assessment of Natural Complex Substances (NCS) is similar to that of discrete fragrance materials; all of the same endpoints are evaluated. A series of decision trees, reflecting advances in risk assessment approaches of mixtures and toxicological methodologies, fo
