    Notes: Abstract This paper discusses the extent to which Australian agriculture is integrating trees into farming systems and concludes that while broad environmental awareness and concern may have increased, Australian agriculture exemplifies essentially the same attitudes to native vegetation as those held by the first European settlers. It is suggested that for real change to occur, land users require three key ingredients — commitment, knowledge and resources. The state of play with respect to each of these key factors is reviewed and suggestions for reform mooted.

    Notes: Abstract We briefly review some general aspects of Bose condensation and off-diagonal long range order in infinite bulk systems and then discuss to what extent these features might be manifested in finite systems with free surfaces such as droplets of liquid 4 He at low temperatures. We focus on the structure of the one-body density matrix and the macroscopic wave function in the surface region, and note the possibility of a surface condensate.
