Pest Management Science, EarlyView.Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Inefficient star formation through turbulence, magnetic fields and feedback
, 2015 Star formation is inefficient. Only a few percent of the available gas in molecular clouds forms stars, leading to the observed low star formation rate (SFR). The same holds when averaged over many molecular clouds, such that the SFR of whole galaxies is

Power transformer dissolved gas analysis through Bayesian networks and hypothesis testing [PDF]
, 2018 Accurate diagnosis of power transformers is critical for the reliable and cost-effective operation of the power grid. Presently there are a range of methods and analytical models for transformer fault diagnosis based on dissolved gas analysis.

Strategic Management Journal, EarlyView.Abstract Research Summary Entrepreneurship accelerators are increasingly promoted as structural interventions to close gender gaps, yet studies have not established a differential impact of participation for women. This prior evidence—drawn from high‐tech, male‐dominated settings—may overlook how outcomes differ in more feminized domains such as social

On column density thresholds and the star formation rate [PDF]
, 2014 We present the results of a numerical study designed to address the question of whether there is a column density threshold for star formation within molecular clouds. We have simulated a large number of different clouds, with volume and column densities

Children &Society, EarlyView.ABSTRACT Mentalisation and symbolisation are important processes to support children in understanding their lived experience. By expressing what is most salient to them through pretend play, children can normally develop their capacity to mentalise and symbolise, which helps them cope with adversity.
