A study of two seed-borne Alternaria diseases on choumoellier : a thesis presented in partial fulfilment of the requirements for the degree of Master of Agricultural Science at Massey University

The livestock industry in New Zealand is based on a pastoral farming economy, an important aspect of which is the utilisation of fodder crops as supplementary feed during seasons of poor pasture growth. Playing an important role in this regard are the two selections of choumoellier (Brassica oleracea var. acephala D.C.) usually referred to as giant choumoellier and medium stemmed choumoellier. The growing importance of choumoellier in feed crop rotations is indicated by the increased area sown, from 8,000 acres in 1933 to 130,000 acres in 1963 (New Zealand Farm Production Statistics, 1962-63). In the past, choumoellier seed has been imported from the United Kingdom, but more recently the trend has been to promote locally grown seed. At the present time New Zealand's requirements are met in most years by South Island growers producing seed under the authority of a Government seed certification scheme. In discussing brassica crops in New Zealand, Palmer (1966) stated that - "apart from weather variations, the main uncontrollable causes of yield variations are fungus diseases, insect pests and associated virus diseases''• Seven fungus diseases are recorded in New Zealand on choumoellier (Table 1), five of which are evidenced by foliage lesioning in field stands

Extending boundaries: young people as action researchers

Action research is generally undertaken by adults as a process of systematic action planning and enquiry which can lead to improvements in aspects of their professional practices. This article challenges and extends conventional understanding of action research to show how young people, between the ages of 10 and 17, can interrogate and improve their own practices – both individually and collectively. Brief accounts of four case studies – three British and one South African – are presented, along the lines of a patchwork narrative. Each ‘patch’ in turn contributes to the later collation of a theme and ideas that ‘stitch’ the studies together

Experimental validation of an integrated FRP and visco-elastic hardening, damping, and wave-modulating system for blast resistance enhancement of RC columns

In today\u27s society, terrorist attacks and accidental explosions pose a major threat to critical infrastructure. Vulnerable to blast loading, structures must be rehabilitated to ensure structural stability and protect human life. The goal of this study is to develop and validate a sandwich composite technology for column retrofitting. The new technology consists of an inner fiber reinforced polymer (FRP) sheet, an outer FRP sheet, and a visco-elastic (VE) layer sandwiched between the two FRP sheets. The inner FRP sheet is wrapped around an existing column for confinement, while the outer FRP sheet is for anchoring of the VE layer into the column supports. The compact, inexpensive, and easy to construct system has been shown effective under seismic loads. In this study, the blast performance of the engineering system is investigated with two main objectives: to field validate the effectiveness of the system for hardening, damping, and wave-modulating (HDM) of a reinforced concrete (RC) column under blast loads, and to validate the performance of coaxial cable crack sensors for dynamic measurements under blast loads --Abstract, page iii

The minimum free-stream wind speed for initiating motion of surface material on Mars

Estimates of the minimum free-stream wind speed that is required for initiating the motion of surficial material on Mars have ranged from 30 to about 200 meters per second. Thus the best value for this quantity is not well established. Graphical comparison of much of the pertinent data taken in the laboratory and in the field on Earth provides a minimum value for the Bagnold coefficient of 0.08 and this in turn provides a minimum value for the threshold friction velocity of 1.3 meters per second for initiating motion of particulate matter on Mars at low elevations where the pressure is 7 millibars. The most appropriate value of the ratio of friction velocity to free-stream velocity for putative unstable condition appears to be 0.026. Thus the minimum free-stream wind speed for initiating motion is obtained as 50 meters per second. If the surface material on Mars, however, is less cohesive than that on earth, the minimum value may be smaller
