title: Investigation of extractable materials from biochar

authors: Yang, Wenjuan

subjects: Biochar

abstract: Biochar has been used to improve soil productivity and has been a subject of discussion since 1804. However, research and development of biochar for environmental purposes on a global scale are a recent development. Due to the increase of its uses and interest in biochar as soil amendment, there is a need to understand the intrinsic chemistry of biochar to understand how this might affect its action in the soil. 

In this work two principal topics were addressed: 
1)	Investigation of volatile organic compounds in biochar that has been derived from various biomasses and the effect of different temperatures of pyrolysis
2)	Identification of some chemical structures of biochar. 

GC-MS analysis identified 60 extractable organic compounds. With respect to pyrolysis temperature, GC-MS results of Green Waste chars and Sucrose chars shows that extractable organic compounds changed their proportions with differing pyrolysis temperatures.  MALDI-TOF and high resolution mass spectrometry results suggested that the characteristic ions for biochar  that appear in MALDI-TOF spectra with m/z values of 301,317, 413,429 and 453 are plasticizers whereas 685/ 701 are ions, [M+Na] ⁺/ [M+K] ⁺ respectively that are intrinsic to biochar.

title: Should physical activity be on the healthy ageing agenda?

authors: Grant, Bevan C.

subjects: physical activity

abstract: Physical activity makes a notable contribution to one’s independence, ability to perform everyday tasks and quality of life in the later years, but engagement in this health-related behaviour decreases with age. It is therefore not surprising that numerous intervention strategies have been applied in many settings to encourage a physically active lifestyle.
Nonetheless, these have little long-lasting effect. Knowing how best to promote such behaviour to people over 65 years old in a way that makes them feel I want to engage is still in its infancy. This paper reflects on how ageing influences the decisions people in later life make in relation to adopting a physically active lifestyle, and how any advocacy needs to look beyond the physical experience. Knowing of the potential benefits to be gained from this self-regulating behaviour means it warrants a more prominent place on the promoting healthy ageing agenda.

title: An indigenous psychologies teaching and research hub : Enabling our resources, strengths and histories

authors: Nikora, Linda Waimarie

abstract: This paper was presented as part of an informal indigenous psychologies dialogue session at the Australian Psychological Society's annual conference. In this paper, we present the concept of an indigenous psychologies teaching and research hub that reduces distance, helps students remain in community, uses resources efficiency, and has the capacity to bring indigenous psychologist and academics into closer communication.
