title: Virtual bioprocess simulation laboratory for teaching and learning

authors: Berenjian, Aydin

abstract: There is great potential in applying virtual technology to support teaching and learning. A 3D virtual bioprocess simulation will enable users to learn about both basics of laboratory safety and fermentation principles. Once procedures and exercises within the simulator have been carried out, users will have a deeper understanding about fermentation principles, common lab procedures, experiment design and analysis of data. This software would be an efficient, low-cost option to educators and students within fields such as Biotechnology, Biology, Biochemical Engineering, Biochemistry, Genetics, Microbiology and more.

title: Structural and thermal performance of cold-formed steel studs with slits

authors: Ghosh, Kushal

abstract: Cold-formed steel (CFS) studs in lightweight construction increasingly incorporate web slits to limit thermal bridging, yet these openings can reduce axial strength. This thesis integrates structural and thermal assessments through validated non-linear elasto-plastic finite element analysis (FEA) and complementary heat-transfer modelling. Shell-element FEA models were developed and validated against tests, then used in a 960-case parametric study spanning section dimensions, slit geometry, thickness, and member length to establish the influence of slits on concentric axial capacity. The results were evaluated against the Direct Strength Method (DSM) in AS/NZS 4600, leading to strength-reduction recommendations and modified DSM expressions that achieve reliability indices β ≥ 2.5. The programme was extended to combined axial compression and minor-axis bending using 1,134 FEA models with six eccentricities, demonstrating a systematic discrepancy in current AS/NZS 4600 interaction checks: strengths are generally underestimated at eccentricities of 10–25 mm and overestimated at 50 mm. A new interaction equation incorporating element and web slenderness ratios is proposed and verified within the AISI S100 reliability framework. Subsequently, a parametric three-dimensional heat-transfer study quantified the dependence of heat flux on geometry and slit parameters, providing a quantitative basis for thermal performance gains and their balance with strength. The thesis proposes design recommendations and revised equations for slitted CFS studs that satisfy codified reliability targets and support informed selection of slit configurations to balance energy efficiency and structural capacity in practice.

title: Te ahunga atu ki ngā ōhanga oranga Māori: Towards Māori economies of wellbeing - Ngā whānau i te pokapū o te oranga

authors: Spiller, Chellie

abstract: Nau mai ki tēnei kohinga o ngā whakaaro me ngā tikanga e pā ana ki te oranga ohaoha Māori. Ko tō mātou kaupapa matua ko te whānau; e hiahia ana mātou ki te whakaatu i ngā huarahi ki te ora pai mō te whānau i roto i ngā horopaki ohaoha. Ko te ao Māori tō mātou tūāpapa. E whakakao ana tēnei pukapuka i te huhua o ngā reo me ngā tirohanga nō te ao Māori, me ētahi atu wheako e hāngai ana. Kua kotahi mātou ki raro i te taumarumaru o te kaupapa tūturu kotahi: arā, te oranga pai mō ngā whānau. Ko te tūmanako ka tautoko, ka whakaohooho anō hoki tēnei pukapuka i ngā tāngata kia hōhonu atu tā rātou hono ki tēnei kaupapa whaitake, kia whai māramatanga whaihua hoki rātou.

Welcome to this collection of thoughts and practices related to Māori economic life. Our primary focus is the whānau; we want to show ways to live well for the whānau in economic contexts. Our foundation is te ao Māori. This book brings together many voices and perspectives from the Māori world and other relevant experiences. We are united in one true purpose: the good livelihood of whānau. We hope this book will support and inspire people to connect more deeply with this critical topic and gain valuable insights.
