The effect of complex training on horizontal power production in rugby union players : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science at Massey University

The use of strength and power training regimes is common place among elite and recreational athletes. However, the application of such methods as direct determinants of improvement in sporting performance is a controversial and much debated topic because the degree of transfer from the training exercise to the sporting application is unknown. In recent years combining strength and sport specific training methods into one training session (complex training) has been promoted as a method to enhance training transfer. The purpose of this project was to examine the effect of complex training on horizontal power production in rugby players. 9 participants completed two four week phases of training (complex and standard) in a randomized order. Participant performance in 5RM squat, horizontal force and horizontal power was tested prior to and at the end of each training phase. A number of significant improvements were observed following complex training: maximum slope of the horizontal force curve increased by 12.29 ±33.59%, maximum power increased by 15.13 ±7.49%, width of the power curve increased by 28.30 ±18.16%, and maximum velocity during the horizontal power test improved by 20.63 ±14.21%. The improvements were significantly different from the respective standard training measures (p ≤.05). It is concluded that power gains were a product of an enhanced ability to produce force at higher velocities. No significant weight gain or significant improvement in 5RM force production was associated with the improvement in maximum power. Therefore it is inferred that neural mechanisms accounted for the difference following complex training. The results presented here suggest that complex training not only improves horizontal power production but also transfers performance improvements to an untrained task by improving the rate of force development in the horizontal force condition. It appears that the complex training regime has in some way created a persistent change in the control mechanisms regulating the performance of both the horizontal strength and power conditions

Stationary solution of the ring-spinning balloon in zero air drag using a RBFN based mesh-free method

A technique for numerical analysis of the dynamics of the ring-spinning balloon based on the Radial Basis Function Networks (RBFNs) is presented in this paper. This method uses a 'universal approximator' based on neural network methodology to solve the differential governing equations which are derived from the conditions of the dynamic equilibrium of the yarn to determine the shape of balloon yarn. The method needs only a coarse finite collocation points without any finite element-type discretisation of the domain and its boundary for numerical solution of the governing differential equations. This paper will report a first assessment of the validity and efficiency of the present mesh-less method in predicting the balloon shape across a wide range of spinning conditions

A Note on 1/4-BPS States

We study classical solutions of N=4 super Yang-Mills theories that are invariant under 1/4 of the supersymmetry generators. Expressions for the mass and electric charge of the configurations are derived as functions on the monopole moduli space. These functions also provide a method of determining the number of normalisable bosonic zero modes.Comment: 10 pages, LaTe

Robotic Astronomy with the Faulkes Telescopes and Las Cumbres Observatory Global Telescope

We present results from ongoing science projects conducted by members of the Faulkes Telescope (FT) team and Las Cumbres Observatory Global Telescope (LCOGT). Many of these projects incorporate observations carried out and analysed by FT users, comprising amateur astronomers and schools. We also discuss plans for the further development of the LCOGT network.Comment: 8 pages, 2 figures, conference proceedings from "Workshop on Robotic Autonomous Observatories", held at Malaga, Spain from 18-21 May 2009, acccepted for publication in Advances in Astronom

Mapping the “housing with care” concept with stakeholders: insights from a UK case study

Purpose - The purpose of this paper is to present the findings of an early stage, exploratory case study of a proposed housing with care initiative (the Crichton Care Campus (CCC)). This sought the perspectives of a range of key stakeholders on the proposed model and how it might be best realised. The analyses of these findings show their relevance to debates on integrated housing with care, and reflect on the methodology used and its potential relevance to similar projects. Design/methodology/approach - The study used a transactive planning approach, where grounded views are sought from a variety of stakeholders. A purposive sample identified informants from relevant health, social care and housing organisations and nine semi-structured interviews were conducted. These were transcribed and data analysis was undertaken on an “interactive” basis, relating care theory to empirical expressions. Findings - The authors identify two contrasting orientations – inclusive “community-oriented” and professional “service-oriented”. This distinction provides the basis for a rudimentary conceptual map which can continue to be used in the planning process. Two significant variables within the conceptual map were the extent to which CCC should be intergenerational and as such, the degree to which care should come from formalised and self-care/informal sources. The potential to achieve an integrated approach was high with stakeholders across all sectors fully supporting the CCC concept and agreeing on the need for it to have a mixed tenure basis and include a range of non-care amenities. Originality/value- This paper offers originality in two respects. Methodologically, it describes an attempt to undertake early stage care planning using a needs led transactive methodology. In more practical terms, it also offers an innovative environment for considering any approach to care planning that actively seeks integration – based on an acknowledgement of complexity, a variety of perspectives and possible conflicts. The authors propose that the concepts of “community-orientation” and “service-orientation” are used as a helpful basis for planning negotiations, making implicit divergences explicit and thus better delineated

Visualisation of fingermarks and grab impressions on dark fabrics using silver vacuum metal deposition

Vacuum metal deposition (VMD) involves the thermal evaporation of metal (silver) in a vacuum, resulting in a uniform layer being deposited on the specimen being treated. This paper examines the use of silver on dark fabrics, thus offering a simpler operation and more obvious colouration to that of the traditional use of gold and zinc metals which must be evaporated separately. The aim of this study was to investigate the effect of fabric type, donor, mark age and method of fingermark deposition on the quality of marks visualised using silver VMD. This was achieved by collecting fingermark deposits from fifteen donors, of both sexes and various ages, by a grab or a press method. Four different fabrics: satin, polyester, polycotton and cotton were studied over a 10 day timeline of 1, 2, 3, 4, 5, 6, 7, 14, 21 and 28 + days. It was found that satin and polyester gave the most positive results, with polyester often producing excellent ridge detail. Cotton and polycotton were less successful with no ridge detail being observed. The donors also had an observable effect on the results obtained probably due to variations in secretions produced or pressures applied during specimen collection. The age of the mark or the method of mark deposition had little influence on the results obtained. Silver VMD is a viable process for visualising marks on certain dark fabrics and has the advantage over gold/zinc VMD in that the marks visualised are light in colour which contrasts well against the dark background
