title: Contextualizing the Common European Framework of Reference for Languages

authors: Valax, Philippe

subjects: Europe

abstract: The article discusses about the establishment of Common European Framework of Reference for Languages (CEFR) after the second World War, then explaining political, social and historical aspects of this organization. As mentioned, it was felt necessary to develop such a framework for language teachers in Europe and outside. The development of the organization was very specific in social and political context, some end notes are also given.

title: Evaluation of reactive induction sintering as a manufacturing route for blended elemental Ti-5Al-2.5Fe alloy

authors: Jia, Mingtu

subjects: Science & Technology

abstract: This work focuses on gaining a better understanding of the feasibility of using reactive induction sintering to obtain the alloy Ti-5Al-2.5Fe using Ti, Al and Fe powders (i.e. via a blended elemental approach). For this, powder compacts were induction sintered under various temperature/time combinations like 700–1250 °C and isothermal holding of 0–15 min. Compositional homogeneity, microstructure evolution and mechanical properties of the sintered Ti-5Al-2.5Fe alloy were investigated. It was found that by increasing the sintering temperature and isothermal holding time, sintered Ti-5Al-2.5Fe components with a homogeneous chemical composition and a Widmanstätten microstructure can be produced. The tensile strength increases with the sintering temperature/time reaching comparable values to the wrought alloy; however the residual porosity has a significant impact on the ductility of the alloy. This study demonstrates that reactive induction sintering is suitable to shorten the production route of blended elemental Ti alloys to be used in non-critical applications where ductility is not the main requirement.

title: The state of the Rotorua Lakes in 2017

authors: Hamilton, David P.

abstract: I have been asked to give an overview of the Rotorua Te Arawa Lakes and then focus on just four of the lakes. Chris McBride will pick up other lakes.  I would like to acknowledge Warwick Silvester who set up the Lakes Chair, Simon Stuart who is working outside the rohe, on Lake Taupō, but has a great body of knowledge on the food chain in that lake, with potential applications to the Te Arawa lakes. Also to Kohji Muraoka who helped me over the last 24 hours, putting data together which enabled me to synthesise my thoughts on these lakes.
