The diet of the Malham Tarn otters: understanding the impacts of a native predator

Otter (Lutra lutra) populations have been recovering in the UK and expanding into new and often isolated habitats. Otters were first sighted at Malham Tarn in 2009, and have since been observed on a regular basis. This study looks at the diet of the Malham Tarn otters and considers their possible impact on prey populations, such as fish, wading birds and white-clawed crayfish

Unified Software for Multi-Functional G-Code: A Method for Implementing Multi-Technology Additive Manufacturing

Additive manufacturing (AM) began a manufacturing revolution moving industrial production into consumer homes. With interest shifting toward multi-functional parts fabricated through AM technologies, multi-functional fabrication systems are now being developed. Merging different manufacturing technologies into a single machine is a challenge, but ongoing research in the development of multi-technology systems has shown promise. The software and automation aspects of multi-technology systems are being developed in unison. This paper explores the challenges and approaches to developing software that interfaces with multifunctional CADs and creates files for direct use in multi-technology AM machines.Mechanical Engineerin
