Sand casting

...techniques. Core sand is mixed with oil, organic bonding material and water. They are moulded in core boxes, then removed and baked at 170–230 ˚C. A newer method of making cores is to bind the core by passing CO2 through it. A wide range of productivity is obtainable from machine mouldings using apparatus such as hand-operated “jolt-squeeze” to massive industrial...

The Bottom Line Expert Opinion: Sponsorship

...techniques. They seek to fund events and public services in order to promote their products – even if only indirectly. This allows them to reach consumers, like children, that they otherwise would not be able to reach. Moreover, it raises serious questions of how “objective” public institutions can be when receiving private funding. This is perhaps particularly...

Fracking: Is it possible to persuade the public that the benefits outweigh the risks

...technique have led to arrests and one even saw designer Vivienne Westwood drive a tank up to David Cameron’s country home. Yet we shouldn’t assume that the adverse public reaction to the shale gas industry is just an emotional response. Averil MacDonald, the chair of oil industry body United Kingdom Operators Group (UKOOG), recently claimed that women were less likely...

Tackling juror trauma and stress

...techniques) are already provided in some states in the US and could be adapted into practice in England and Wales. Within the trial itself, research is essential to discover which modalities and approaches to information presentation minimise trauma, and which are likely to exacerbate it. Mental health specialists within court could help jurors verbalise their anxieties,...

Is there life on Mars?

...techniques to try and find those pesky critters. The cascade of the chemical reactions of life is messy and leaves a series of footprints in the environment when it happens, what we call biosignatures – these can range from minerals, to organic molecules, or gases, just to mention a few. Gases are particularly interesting since they easily travel from the point they...

60 Second Adventures in Artificial Intelligence

...techniques could be used to process data from a next-generation radio telescope – the Square Kilometre Array. Transcript Training AIs for the Scientific Data Deluge In the coming decade, next-generation facilities like CTA, SKA and the Rubin Observatory will generate vast datasets that will be impossible for humans to manually filter and analyse. We would like to train...

Opening up history: political culture in eighteenth-century Ireland

...techniques. When I encountered early modern history as an undergraduate, I was particularly drawn to the history of printing and the press. I was interested not only in print as a technology, but in what it enabled in terms of the circulation of ideas and information. My PhD project focused on print in Ireland in the late seventeenth and early eighteenth centuries, and my...

Revealing the surface of an asteroid using robotic telescopes

...technique called relative aperture photometry to obtain lightcurves (measurements of brightness over time). As the asteroid rotates, a different surface area reflects light from the Sun back towards Earth, with a higher reflecting area leading to an increase in observed brightness from Earth and vice versa. These lightcurves will therefore provide information about the...
