title: Experimental determination of natural convection heat transfer coefficients in an attic shaped enclosure

authors: Anderson, Timothy Nicholas

subjects: triangular enclosure

abstract: Heat transfer by natural convection in triangular enclosures is an area of significant importance in applications such as the design of greenhouses, attics and solar water heaters. However, given its significance to these areas it has not been widely examined. In this study, the natural convection heat transfer coefficients for air in an attic shaped enclosure were determined for Grashof Numbers over the range of 10⁷ to 10⁹. It was found that the measured heat transfer coefficients could be predicted to within 5% by Ridouane and Campo’ [1] equation (Eqn. 1) for natural convection in a triangular enclosure previously developed for Grashof Numbers in the range 10⁵ and 10⁶ . 
Nu = 0.286A-.286GR1/4 (1)
As such, it is suggested that this equation may be suitable for predicting the natural convection heat transfer coefficients in full scale attic enclosures.

title: Technology education in the New Zealand curriculum

authors: Jones, Alister

abstract: In this chapter, the way in which experience of existing school programmes influences teacher perceptions of technology education is discussed, and reasons for teaching technology are outlined. A relationship between technology and technology education is suggested and the structure of technology education in the New Zealand technology curriculum is described. A particular focus is the role of technological activities in technology education, and this is developed in the final section.

title: Taku haumaru me te kurī - Te Reo Maori

authors: Carter, Jennifer

subjects: dog safety tips

abstract: This safety leaflet designed to target young children aged 5-6yrs will provide an age-appropriate understanding of how to avoid pet dog attacks which can injure, maim and even kill children.    This research-based educational resource provides practical, valid and reliable guidelines for safe interaction between children and pet dogs in their homes or known to them.  
The content of this leaflet has been drawn from ‘Stories with happy endings: Preventing pet dog attacks on children’, the 2007-2008 Summer Scholarship report prepared for the Child Accident Prevention Foundation of New Zealand (CAPFNZ).
