Full textAbstract:
The overall purpose of this thesis was to examine the physical aspects of high performance soccer. As such, four interrelated studies were designed to pursue this purpose. Each study was designed to overcome certain distinct methodological limitations of previous science and football (soccer) research and build upon existing research. The research designs for each of the four studies were methodologically different and progressed from previous research design incorporating data collected and analysed from text and internet sources, computerised video-analysis of interactive televised material and combined performance and laboratory assessments. In the following section the purpose of each study included in this thesis is provided and the rationale underpinning the selection of each research design is explained. Study 1: Analysis of Age, Stature, Body Mass, BNH and Quality of Elite Soccer Players from four European Leagues For many sports, there are specific physical characteristics that indicate suitability for, or potential to compete in that sport at the highest level. Various anthropometric characteristics of athletes have been shown to be reasonable predictors for participation at the highest level in sports such as swimming (Ackland et al., 1993), basketball, rugby league and American football (Norton and Olds, 2000). Surprisingly, there is no research available exploring these characteristics in soccer, particularly within the elite European soccer. It might well be that the recent changes in demands in soccer( Williams et al., 1999) PhD Thesis 6 Jonathan R- Bloomfield have been accompanied by physical characteristic changes in soccer players that have been of greater magnitude than that of the normal population. This is an important issue because even small changes in these physical characteristics of players could result in a large reduction in the pool of people to draw from in the general population who have the suitable physical characteristics to be successful in soccer (Olds, 2001). Furthermore, the comparison of players in different leagues and in different positions might provide some valuable information regarding the different demands placed on soccer players in different leagues (Reilly et al, 2000a; Rienzi et al, 2000; Strudwick et al., 2002). It is well documented that different positions in soccer constitute various different demands. Such findings suggest heterogeneity in physical characteristics that might be important for success in particular positions in soccer (Strudwick et al., 2002). The first aim of the present study was to investigate whether there are physical differences (age, stature, body mass, body mass index) between players in different positions in four European soccer leagues. This will also provide information into the diversity in playing style as well as the variation in what is being valued in soccer players in the various countries. This results in valuable information for the adaptation of different physical conditioning regimes as well as implications for talent identification (Fisher and Dean, 1998). The second aim of the present study was to assess the quality of the players of each of the four European leagues by surveying their international status, nationality and FIFA world ranking as well as participation in the FIFA World Cup 2002. This will offer information regarding the actual quality of international players within these leagues which, in turn, provides information about which league would be of the highest quality, differences in playing style and player selection. As the four leading European leagues were selected for analysis, the results provide beneficial information concerning the current status and possible future development of European soccer. Study 2: The 'Bloomfield Movement Classification': Motion Analysis of Individual Soccer Players In close relation with the investigation of the physical characteristics of elite level players, it was also aimed to identify the physical demands of performance. Computerised video-analysis was selected as the most appropriate platform to incorporate a study using the time-motion analysis methodology. This involves the notation of various subjectively or objectively chosen modes of motion which are digitally timed throughout the performance. To date, fewer than 8 modes of motion have often been chosen in time-motion investigation in soccer which arguably does not provide a sufficient degree of specificity to detail the physical demands. A high element of performance specificity must be established to elicit a high degree of transfer from competition into a training regime to optimise competitive performance (Henry, 1968; Barnett et al., 1973; Sale and MacDougall, 1981; Rosenbaum, 1987; Morrissey et al., 1995; Hill et al., 1998). The present study outlined a new approach to time-motion analysis through a method involving a greater depth of detail concerning modes of timed-motion, as well as other non-timed movements, directions, intensities, turning and 'On the Ball' categories. The aim of this study was to present a new methodology and establish reliability. The purpose was to provide a new method to perform a more detailed time-motion analysis study in soccer performance to be used in the third study of this thesis. PhD Thesis 8 Jonathan R. Bloomfield Study 3: Physical Demands of Outfield Positions in FA Premier League Soccer. To elicit an enhancement in soccer performance, it is considered important to analyse the physical demands of match-play (Reilly and Thomas, 1976; All and Farrally, 1991a; Hughes, 2003). Time-motion analysis has been used to investigate these demands. However, many limitations exist with previous research, one of which being the range of classifications used in the collection of data- A high degree of performance specificity is desired to improve coaching practices such as physical conditioning (Barnett et al., 1973). To this end, a new time-motion analysis methodology was designed (see Study 2) and aimed at providing a new level of specificity of performance into the physical demands of high level soccer. Also, the majority of soccer-related time-motion analyses have reported macroscopically with total frequency, total duration or total distance covered providing a summary of the overall physical requirements of soccer. As soccer match-play is essentially an intermittent exercise (Bangsbo, 1994e), it is important to progress the knowledge of the physical nature of the sport and further provide a higher level of specific detail. The aims of the present study were to provide detail regarding intermittent patterns of Purposeful Movement (PM) and Recovery (R), performed by players of three different positions (defender, midfielder and striker), to investigate the reoccurrence of bouts of PM and R within selected time phases and finally provide time-motion analysis of the PM using the BMC. PhD Study 4: Effective Conditioning for Soccer Match-Play The interaction of multiple dynamic physical activities often produces a hybrid of physiological and biomechanical stresses. Higher levels of soccer require increased levels of physical fitness through increased demands from high intensity activity (O'Donoghue et al., 2001; Strudwick and Reffly, 2001; Mohr et al., 2003). Therefore, increased ability to perform complex chains of movement skills (agility) in conjuncture with speed (both acceleration and deceleration) and quickness (overcoming inertia) are relative to high level performance (Withers et al., 1982; Bangsbo, 1992; Reilly, 1994a). This occurs through processes of motor learning and physical conditioning with the rules of specificity and overload as key underlying principles.

Tu, Mei Hsien. "Physical characteristics of chemically propelled colloids." Thesis, University of Sheffield, 2013. http://etheses.whiterose.ac.uk/4531/.
Full textAbstract:
Understanding the transport properties of microorganisms in fluid is a fundamental problem in soft matter physics, and the dynamics of an active colloid in non-equilibrium statistical mechanics has recently attracted pioneering investigations into the design of artificial swimming robots at the microscale. A topical review of the remarkable discoveries in the field, both theoretically and experimentally, is first addressed. The mechanism of interfacial phoretic transport is used for an active colloid achieving autonomous propulsion by diffusiophoresis. A theoretical framework has been established to ascertain the generic properties of the active motion of such a self-propelled colloid, driven by the use of surface catalytic reactions. The kinetic route for the chemical reaction is considered as a two-step process, followed by quantitative procedures that examine the influence of fuel concentration and colloid size on the propulsion velocity. Specifically, both Janus and inhomogeneous colloids are studied, and their propulsion velocities rise linearly with the fuel concentration in a dilute solution and decay with the size scale in the small size limits. The theoretical results for a Janus sphere are consistent with the experimental observation. Furthermore, to what extent can the incorporation of advection into the diffusion be interpreted as a means of self-propulsion. An advection-diffusion model is constructed to compute the concentration distribution of the solute and propulsion velocity, aiming to explore the role played by the advection effects on the movement of Janus particles. The numerical results show that while Janus particle can achieve an autonomous propulsion at a small P\'eclet number, the accumulation of solute particles in the upstream of the colloid disappears at the large Pe limit. In conclusion, the major outcome of this work is the demonstration of the qualitative agreement with the present analysis of mobility to explain the observed size dependence. Lastly, the results suggest that a catalytic colloid powered by diffusiophoresis is a useful model for self-propulsion and indicate what still needs to be done to obtain a full understanding of the swimming characteristics of colloidal dispersions.

The aim of this study was to identify indictors of performance in surfing. Therefore the objectives of the study were to determine the following: {u100085} Anthropometric measures such as: height, weight, body proportions; {u100085} Flexibility measures such as: back extension, hip flexion, ankle plantarflexion and dorsiflexion; {u100085} Core stability; {u100085} Dynamic balance; {u100085} Explosive leg power; {u100085} Which of the physical characteristics measured discriminate between elite and non-elite surfers. To achieve the aim and objectives of this study, the literature pertaining to excellence in surfing, and the theory surrounding talent identification and the many factors that can contribute to success in sport, were reviewed. Potential criteria important for performance in surfing were identified and appropriate tests to assess these criteria were selected. An ex post facto quasi experimental design was used to assess which of the identified criteria best discriminated between elite and non-elite surfboard riders. The test battery included a personal information questionnaire and the assessment of: anthropometric variables, flexibility, core stability, dynamic balance and explosive leg power. These abovementioned physical characteristics were identified from the literature as the factors most important to success in surfing. Fifty five (55) surfers were assessed of which 28 were elite surfers and 27 were non-elite surfers. The results obtained from the evaluation of the samples were compared in terms of their descriptive statistics and the differences tested for statistical and practical significance. The variables of height, age started surfing, core stability, dynamic balance, number of days surfed per week and number of hours surfed per day were found to most discriminate between the elite and non-elite participants. Finally, a stepwise discriminant analysis was used to determine classification functions that could be used for future prediction purposes. The variables included in the discriminant analyses included height, age started surfing, number of years surfing, core stability and dynamic balance. To verify the prediction model a jack-knife procedure was performed. The results from the jack-knife procedure indicated that 85.5 perecent of the entire sample was correctly classified while 92.9 percent of the elite sample and 77.8 percent of the non-elite sample were correctly classified. Thus, the discriminant functions obtained can be used for predictive purposes.

Full textAbstract:
This report explains the fundamental theory and equations used in writing a set of software applications which predict antenna radiation parameters. Each application predicts the radiation characteristics of a particular type of antenna over a planar surface which serves as a model of either earth or seawater. The radiation parameter predictions are based solely on an antenna's physical dimensions, the properties of the underlying surface, and electromagnetic theory. Existing electric field equations provide the basis for radiation parameter predictions, and the accuracy of the predicted radiation parameters is totally dependent upon the extent to which the electric field equations used realistically model the actual radiated electromagnetic fields of the antennas. In addition to a review of applicable electromagnetic field theory, this report is also intended to be a user's guide for the corresponding computer applications. The appendices contain computer hardcopies of sample calculations for several antenna types and remarks regarding the conformity of predicted radiation parameters to expectations. Radiation parameters computed thus far are consistent with expectations based on other computational programs and empirical measurements

Full textAbstract:
Aluminium sulphate, calcium nitrate, and two cationic polymers have been used to coagulate and flocculate dilute kaolin and latex suspensions (< 100 mg/1) in a stirred vessel. The effects of the different destabilising agents on the resulting floes have been monitored using a simple continuous optical technique based on turbidity fluctuations and the behaviour of these floes under shear conditions and the possibility of subsequent floe re-formation have been investigated. The results showed vast differences in behaviour regarding to floe breakage and re formation between the systems. For a low molecular weight, high charge polymer (A) and calcium nitrate, floe breakage was almost completely reversible. However, for aluminium sulphate, limited floe re-formation was observed on restoring previous shear conditions after breakage. For a high molecular weight polymer (B), limited floe breakage was observed. Moreover, a new automated monitoring technique based on cake and vacuum filtration has been developed to assess the filterability of floes. The technique is reliable and provides reproducible results. The results showed that polymer A was more effective in enhancing filterability than polymer B for both kaolin and latex suspensions. However, polymers do not have a significant influence on the filterability of floes if the primary particles involved have high sphericity.

Hydrogenated amorphous silicon films subjected to KrF excimer laser irradiation with a profiled beam in air leads to the formation of microstructures. The main objective of this research was to perform a comprehensive study in understanding this material in three different aspects: thermal, electrical, and optical properties by experiment, SEM analysis and modelling. For the thermal interactions, analysis was carried out to investigate factors relating to the formation of the microstructures in a range of applied laser fluences from 93.8 to 443.8 mJ/cm2. The tallest microstructures were formed with average height from 1 to 3 ?m at laser fluence of 312.5 mJ/cm2. Investigation also include the effect of different applied laser fluence, different scanning schemes, the effect of the presence of 300 nm metal layer, and irradiation environment. Thermal modelling using COMSOL simulation software was used to simulate heat transfer during laser-material interaction and the results suggest a fair agreement with experimental findings. SEM and TEM reveal that the material formed was an oxynitride with embedded particles of crystalline silicon. In the electrical part, conductivity and field emission were the main tools to help elucidate the internal structure. Arrhenius plots acquired from conductivity measurements demonstrates a decrease in activation energy from 0.8957 eV from original sample to 0.3955 and 0.1727 eV for HE and LE sample respectively. Analysis also showed an agreement with Meyer Neldel rule for both samples. Observation made on the ratio of dark current to photogenerated current revealed the decrease from 59600 in original sample to 1.77 and 1.40 for HE and LE samples respectively. For the field emission properties, IE plots from samples were analysed using 170 ?m fixed gap structure, and lowest emission thresholds were achieved at 3 and 2.4 V/?m for HE and LE samples respectively. The results were fitted to a model of conducting particles in an insulating matrix offering a transport route to the surface. In the optical part, FTIR measurements were carried and analysis in IR absorbance profile within range of 550 to 2200 cm-1 demonstrates SiHx absorbance peaks at 640 cm-1, between 1980 to 2100 cm-1, and at 2095 cm-1. Hydrogen content was found to be decreased with the increase in applied laser fluence from 12 % in original sample to 4.2 and 1.5 % for HE and LE sample respectively. Measurements using UV-Vis between wavelengths of 200 to 1100 nm shows high absorbance up to 98% for laser process sample from 218.8 to 312.5 mJ/cm2. TR analysis demonstrated increasing absorbance properties at increasing incident angle. Raman spectroscopy showed an increase in the crystal fraction with laser fluence. The final analysis work in this thesis examines the material as a potential disordered photonic crystal and studies the propagation and localisation of light in ordered and disordered photonic crystal, modelled using COMSOL simulation software. This shows the transition from diffusive to localised propagation. A number of applications are suggested for this structured material. This is the first report of a new large area ‘black silicon’ material that has a number of interesting applications.

Published ArticleFly Ash is a by-product at thermal power stations, also otherwise known as residues of fine particles that rise with flue gases. An industrial by-product may be inferior to the traditional materials used construction applications, but, the lower the cost of these inferior materials make it an attractive alternative if adequate performance can be achieved. The objective of this study is to evaluate the chemical and physical effectiveness of self-cementing fly ashes derived from thermal power stations for construction applications with combined standards. Using laboratory testing specimens, suitable types of Fly Ashes namely: Kendal Dump Ash, Durapozz and Pozzfill, were tested to the required standards to evaluate the potential properties. All three Fly Ashes have been classified as a Class F Fly Ash, which requires a cementing agent for reactions to take place and for early strength gains in the early stages of the reaction processes. The Fly Ashes conformed to the combination of standards and have shown that the proper reactions will take place and will continue over period of time. The use of fly ash is accepted worldwide due to saving in cement, consuming industrial waste and making durable materials, especially due to improvement in the quality fly ash products.

Full textAbstract:
Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Besides abnormities within the respiratory system COPD is also associated with effects outside the lungs, so called systemic effects. One systemic effect that has been highlighted is skeletal muscle dysfunction which has also been associated with reduced exercise capacity. Apart from changes in muscle morphology, low levels of physical activity have also been suggested as a plausible mediator of reduced exercise capacity in COPD. The aim of this thesis was to study muscle morphology and physical activity patterns in patients with different degrees of COPD and to examine the associations between muscle morphology, physical activity and exercise capacity in these patients. Skeletal muscle morphology was found to shift towards a more glycolytic muscle profile in COPD patients and changes in muscle morphology were found to be correlated to disease severity and to exercise capacity. Muscle capillarization was also found to be lower in COPD compared with healthy subjects and to be correlated to disease severity and exercise capacity. When studying signalling pathways involved in muscle capillarization, an overexpression of VHL was found in patients with mild and moderate COPD compared with healthy subjects. Furthermore, COPD patients were found to be less physically active compared with healthy subjects and the level of physical activity was associated with exercise capacity.In conclusion, changes in skeletal muscle morphology and low levels of physical activity are present in COPD patients and may partly explain the lower exercise capacity observed in these patients. The more glycolytic muscle profile in COPD is suggested to be mediated by hypoxia and low levels of physical activity in this patient group. Furthermore, increased levels of VHL may lead to impaired transduction of the hypoxic signalling pathway, which may contribute to the decreased muscle capillarization observed in COPD.

Full textAbstract:
The home is supposed to provide support and safety for children but can also be the place where children suffer abuse and other adverse treatment by their parents. Violence against children in homes has been banned in Sweden for more than 30 years but it is still a considerable problem in the society and a threat to public health. The overall aim of this thesis was to create comprehensive knowledge of the phenomenon Child Physical Abuse (CPA) in Sweden after the ban on corporal punishment. The focus has been on examining the characteristics of cases reported to the police as well as self-reported CPA, prevalence of CPA and finally associations between CPA and health-problems/risk-taking behaviors among adolescents. Two samples are used in this thesis. The first comprises cases reported to the police during 11 years (n=142) in a Swedish police-district and the second is a population-based youth survey of the total number of pupils in three different school grades (13, 15 and 17 years old) in Södermanland County, Sweden. Cases of severe abuse constituted 14 % of the total number of cases reported to the police. The main difference between the group of severe cases and the remaining was the higher occurrence of convictions in court in the severe cases and the pattern of reporting to the police. The severe cases were reported by agencies to a greater degree than minor cases. Cases of severe abuse were characterized by an accumulation of risk factors in different areas as perpetrator factors, stress- and strain factors, factors of insufficient social network and finally child-related factors. In the cross-sectional study a prevalence of 15 % was found for self-reported CPA (n=8 494). There were associations between risk factors in different areas and abuse and there was a dos-response relationship between risks and reported abuse. It was shown that children who reported parental intimate-partner violence were at considerably higher risk for CPA than other children and that only 7 % of the children exposed to violence had disclosed this to authorities. The study of associations between health and risk-taking behaviors, were performed among the 15 and 17 years old pupils (n=5 933). Associations with health-problems and risk-taking behaviors were shown and the associations became stronger when the pupils reported repeated abuse. Finally there was a cumulative effect of multiple abuse in the form of being exposed to child physical abuse plus other types of abuse (parental intimate partner violence, bullying and being forced to engage in sexual acts) and the associations increased with the number of concurrent abuse.

Prentice, S. J. "Bulk properties and physical characteristics of stripped-envelope supernovae." Thesis, Liverpool John Moores University, 2018. http://researchonline.ljmu.ac.uk/8731/.
Full textAbstract:
Stripped-envelope supernovae (SE-SNe) are a subset of core-collapse supernovae; the explosive death of a massive star. Their defining characteristic is the lack of promi- nent He and/or H envelope suggesting significant mass loss prior to explosion. Their progenitors may be high mass single stars (> 30 M⊙) or lower mass stars that are stripped via binary interaction. Since their discovery as a separate population in 1983, and until recently, the data on these objects steadily increased. SN discoveries have increased year on year since the early 2000s with the advent of targeted and untargeted surveys looking at the skies for transient objects. As a result, some of these surveys have amassed photometric and spectroscopic data on a large number of SE-SNe. The last few years has seen this data made available, dramatically increasing the number of objects with data. I present an investigation into the bulk properties of SE-SNe, using a large database accumulated from public sources, the Palomar Transient Factory, the Public ESO Spectroscopic Survey of Transient Objects, and my own observations. I begin the investigation by constructing and analysing the largest set of bolometric light curves of SE-SNe to date – 85 objects. The light curves are analysed to derive temporal characteristics and peak luminosity Lp, enabling the construction of a lumi- nosity function. Subsequently, the mass of 56Ni synthesized in the explosion, along with the ratio of ejecta mass to ejecta kinetic energy, are calculated. It is found that broad-lined SNe Ic (SNe Ic-BL) and gamma-ray burst SNe are the most luminous sub- types with a combined median Lp, in erg/s, of log10 (Lp)= 43.00 compared to 42.51 for SNe Ic, 42.50 for SNe Ib, and 42.36 for SNe IIb. It is also found that SNe Ic-BL synthesize approximately twice the amount of 56Ni compared with SNe Ic, Ib, and IIb, with median MNi = 0.34, 0.16, 0.14, and 0.11 M⊙, respectively. SNe Ic-BL, and to a lesser extent SNe Ic, typically rise quicker than SNe Ib/IIb; consequently, their light curves are not as broad. Next I examine the spectroscopic properties of these SNe using analytical methods. For He-rich SNe, the presence of H becomes the focus. The strength, velocity, and ratio between absorption and emission of H are measured, along with additional analysis of He I lines, in order to categorize the SNe. The He-poor SNe are ordered according to the number of absorption features N present in the spectra, which is a measure of the degree of line blending. The kinetic energy per unit mass Ek/Mej is strongly affected by mass at high velocity, and such situations principally occur when the outer density profile of the ejecta is shallow, leading to the blending of lines. Using the results, the existing SE-SN taxonomic scheme is adapted I then present the data and analysis of 19 SE-SNe observed since 2012. These SNe are analysed within the context of the earlier findings in this work, as well as exam- ining the ejecta mass distributions as derived from an analytical light curve model. The results support the assertion that SE-SNe reside in a parameter space which is still under-sampled as approximately 20 – 25 percent of these objects have properties that deviate significantly from that of the bulk population. The statistics of the ejecta mass distributions also provide evidence that these SNe arise from relatively low mass progenitors (< 25 M⊙) as the mean ejecta mass for all SN types is 2 – 4 M⊙. Furthermore, distribution of ejecta mass appears unimodal, which suggests that SE-SNe are preferentially arising from one channel; stars that undergo binary interaction. Understanding SE-SNe is important as their stripped pre-explosion progenitor stars are hot, making them sources of ionizing radiation. Their explosions influence their local environment by injecting energy, both radiative and kinetic, and seeding the ISM with the ashes of nucleosynthesis. Finally, they are a source of neutron stars and stellar mass black holes in the universe, which gives rise to other astrophysical events such as X-ray binaries, pulsars, and strong gravitational wave events.

Parsonage, Joanna. "Gender differences in physical performance characteristics of competitive surfers." Thesis, Edith Cowan University, Research Online, Perth, Western Australia, 2018. https://ro.ecu.edu.au/theses/2133.
Full textAbstract:
Competitive surfing is judged on the performance and complexity of innovative and progressive manoeuvres. As such, surfers require the physical attributes of strength and power in both the upper and lower-body in order to facilitate performance. To date, there remains limited research pertaining to the physical performance characteristics of competitive female surfers, making it difficult to quantify the current gender gap in performance attributes. Therefore, the purpose of this thesis was fivefold: (1) to describe and compare the gender differences in physical performance characteristics of competitive surfers; (2) to investigate the reliability and validity of the isometric push-up (IPU), dynamic push-up (DPU) and force plate pop-up (FP POP) measures of upper-body strength qualities; (3) to examine the gender differences in the dynamic strength index (DSI) and dynamic skill deficit (DSD); assessing upperbody dynamic and sports-specific strength relative to maximal isometric strength; (4) to investigate the gender differences in kinetic and kinematic variables of the countermovement jump (CMJ) and squat jump (SJ); and (5) to assess the gender differences in resistance training self-efficacy (SE) and outcome expectancy (OE). The aforementioned studies provide strength and conditioning practitioners, as well as surf coaches, with the data to make evidence-based decisions in the application of training to the female surfers and bridge the gender gap that is apparent within competitive surfing. Study one informed competitive male surfers had more developed physical performance characteristics in the upper and lower-body than female surfers. The findings of this study highlighted the performance benefits that female surfers may experience if such physical qualities are targeted through structured and periodised training. Study two demonstrated the IPU, DPU and FP POP to be reliable measure of upper-body isometric, dynamic and sports-specific strength. Furthermore, the results of this study identified maximal upper-body strength to be strongly associated with the ability to apply force dynamically (DPU and FP POP). These findings apply novel methodologies, in order to better understand the upper-body sports-specific strength qualities of surfers. Study three reported no gender differences in DSI or DSD ratios. However, competitive male surfers applied greater upper-body isometric and dynamic PF application, and greater sport-specific force application (FP POP). These findings, in conjunction with study two, suggest female surfers may benefit from improving their upper-body maximal strength, thus facilitating their ability to apply force in a sports-specific context. Study four demonstrated competitive male surfers achieved an increased jump height by applying a significantly larger normalised concentric impulse in both the CMJ and SJ. These findings may be attributed to the greater countermovement depth exhibited by males, enabling a greater distance over which force can be applied. Study five found no significant difference in resistance training SE or OE between competitive male and female surfers, with similarly high values being reported for both genders. Therefore, resistance training SE and OE in the examined cohort does not seem to be a confounding variable that interacts to elicit the physiological gender differences of competitive surfers.

Therapy to restore functional movement of stroke patients is based on assumptions about what deficits occur in motor control as a result of stroke. These assumptions are derived from observational studies of movement behavior. The success of therapy to restore voluntary movement has been limited, perhaps as a result of insufficient information concerning the characteristics of movement post stroke. Technology now exists to quantitatively describe the characteristics of movement behavior. In this study WATSMARTtm, a non-contact, optoelectric motion analysis system, was used in combination with surface electromyography to measure voluntary movement in the symptomatic and nonsymptomatic arms of five subjects with left hemiparesis as they attempted to reach to one of three targets placed to require movement inside and outside of extensor synergy. Each subject was tested five times over approximately a nine week period. Results indicated that the symptomatic arms were significantly less able to generate muscular activity and to move in a smooth coordinated way [execute the program] than the nonsymptomatic arms whose scores were essentially within normal limits. Target location made no significant difference to the speed or smoothness of movement, but did significantly affect level of muscle activity because of the biomechanical demands of each location. Over the two month period, there were no significant improvements in the nonaffected arms, as would be expected. In the affected arms, amplitude of peak velocity and sense of limb position significantly improved. Improved amplitude of peak velocity was related more to a decrease in the discontinuity of movement (r=-.49, p<.02), a sign of increased maturity of reach, than to electrical activity of the prime movers (anterior deltoid: r=.l9; biceps: r =.37, p<.05). Since the goals of therapy to restore functional movement are to reverse deficient aspects of movement, the findings suggest that strengthening and relearning of motor programs would be appropriate therapeutic goals for these patients. The effectiveness of therapy to actually reverse these deficits must, of course, be established in future studies.

The purpose of this study was to develop a physiological profile of elite Australian Youth soccer
players. Over three years, 150 players from the U'17, U'20 and U'23 national squads were tested
for six measurements - height, weight, sum of eight skinfolds, vertical jump, maximum oxygen
consumption and speed over twenty metres. Comparisons were made between those selected
in the final team (classified as Successful) and those who failed to be selected (classified as
Unsuccessful) to determine any significant differences between the two groups A physical and
physiological profile was obtained for each player - expressed as a single value in both numerical
and graphical formats. Players were ranked based on this score to determine significant
differences between successful and unsuccessful players.
Several significant differences (p<0.05) were found between Successful and Unsuccessful
groups for a number of the variables primarily in the performance area rather than in the
anthropometry parameters. For all squads, significant differences (P<0.05) were found between
those who made the squad and those who did not when ranked based on their physical and
physiological score.
This study highlights the importance of the application of scientific testing to soccer Furthermore,
it provides a system by which players' results can be analysed and ranked, and expressed in a
format that provides the coach with immediate feedback as to an individual's specific strengths
and weaknesses as a basis for training and team selection.

Landslides are treacherous, but risk management actions based on improved prediction of landslide runout can reduce casualties and damage. Forty rapid flow-like landslides of variable volume, entrainment, and composition are used to develop a volume-runout regression, which is compared to those established in previous research.
The cases are analyzed to identify the most critical characteristics observable prior to failure which differentiate between events of high and low mobility.
Mitigating long-runout flow-like landslides requires accurate hazard mapping, a task best accomplished through runout modelling.
Current practice requires back-analyzing a set of cases consistent in scope with the target event, then applying the same rheology and parameters to forward modelling. This thesis determines which aspects of scope are most important to prioritize when selecting similar cases, as volume, movement type, morphology, and material have a more substantial influence on mobility than other physical characteristics.
Statistical analysis of the performance of frictional and Voellmy rheologies over a range of parameters for the forty case studies provides the expected mean normalized runout and associated standard deviation, and recommendations for parameters to use in initial forward modelling of prospective events.

Full textAbstract:
The purpose of this study was to examine child psychosocial adjustment (i.e., behavioural problems and self-esteem) as a function of maternal well-being, parenting competence, and maternal stress in a sample of children (8 to 16 years) with a chronic physical disorder (CPD) (n = 60) as compared to a sample of non-chronically disabled children (n = 60). While the groups did not differ on either maternal variables or child behavioural problems, CPD children had higher self-esteem than comparison group children. For both groups, mothers with high well-being, high competence, and low stress had children with fewer behavioural problems. Furthermore, mothers of older CPD children perceived themselves as more competent parents, which in turn was related to fewer behavioural problems and higher self-esteem in the child. Mothers who assessed their child's condition as less stressful also had a higher sense of well-being and/or perceived themselves as more competent mothers. While this sample consisted of children whose conditions were of mild to moderate severity, children with more severe conditions had higher self-esteem.

Full textAbstract:
Mixed martial arts (MMA) is a combat sport that includes striking and grappling contested under a unified ruleset. While research exists investigating various physical and physiological characteristics that are potential indicators of greater performance in MMA, there is no consensus on which characteristics are essential to performance and best practice for assessment of such characteristics. Strength has been identified as a predictor of performance in combat sports including MMA, wrestling, and Brazilian Jiu Jitsu (BJJ). Aerobic and anaerobic conditioning has been explored in combat sports including BJJ, judo, boxing, kickboxing, and MMA and have varying relationships to higher-level performance. Characteristics such as repeat effort ability, flexibility and body composition have also been investigated but the literature lacks depth and nuance. It may also be important to consider athletes from diverse combat backgrounds may show a range of physiological profiles, while still being competitive under the same unified ruleset. As such, there are a multitude of technical and physiological characteristics that contribute to competitive success. Developing a single scientific assessment that can predict competitive outcomes poses great difficulty due to the complexity of MMA. While previous research has investigated some important physiological characteristics, there is no accepted best-practice for a comprehensive testing battery. As such, this study aimed to design and utilize a battery of physiological assessments to cover aerobic and anaerobic function, maximal strength, force generation, body composition and repeat effort ability in Australian MMA athletes. Six participants (height: 174.5 ± 5.7 cm, body mass: 84.5 ± 23.4 kg, age: 25.7 ± 4.7 years) with differing competitive experience were recruited. Testing involved one familiarization and three experimental sessions. Experimental session one encompassed countermovement jump assessment and a Wingate anaerobic test, experimental session two included the isometric midthigh pull and repeat sled push test while experimental session three concluded with a DEXA scan and a graded treadmill exercise test. Each experimental session was separated by 48 hours. The battery designed for this study was comprehensive based on the characteristics identified by previous research and considerate of current best practice methods in athlete testing. We found that the comprehensive battery was feasible for athletes to complete within seven days including familiarisation days and could be used in both practical and research settings Results showed that regional Australian MMA athletes possess similar physiological characteristics to elite standards in measures including strength (mean strength 3.32 ± 0.67 N/kg; range 2.44 – 4.09 N/kg), anaerobic capacity (mean average power 614.17 ± 89.15 W; range 510 – 770 W) and aerobic capacity (mean VO2max 54.06 ± 13.83 ml/kg/min; range 31.15 – 70.14 ml/kg/min) while countermovement jumps (mean jump height 27.02 ± 6.3 cm; range 17.85 – 33.34 cm) were well under elite standards compared with values taken from a range of sources. While comparisons to other populations should be seen as speculative due to the small sample size, this is the first Australian-only sample of MMA athletes assessed using these measures. The results of this thesis can help inform athletes, researchers, and support staff alike when deciding upon which testing protocols to use for MMA athletes. Future research should aim to develop normative data using the battery proposed in the current study.

Full textAbstract:
In-depth, open-ended interviews were conducted with 16 expert Canadian coaches from the team sports of basketball, volleyball, field hockey, and ice hockey. The purpose of the interviews was to better understand the perceptions of expert team sport coaches regarding the characteristics, knowledge, and strategies that operate within their profession, and then to conceptualize the relationships between these various elements. Interviews were transcribed verbatim, and the unstructured qualitative data were analyzed inductively following the procedures and techniques outlined by Cote, Salmela and Russell (1995b). This process allowed the meaning units of the interview transcripts to be grouped into 79 tags and then regrouped into 22 properties. Six categories emerged from the analysis: coach-centered processes, organization, training, competition, athlete-centered processes, and contextual factors. The coach-centered processes category included the coaches' characteristics, knowledge, and strategies about personal growth and development, and ways of nurturing this process through continuous learning. The tasks of organization, training, and competition were central to their profession, with organization representing the point of departure of the other two categories since it was the foundation for training competition. These coaches were more than just efficient organizers, they were also highly motivated individuals who understood the magnitude of effectively outlining a global perspective to their team and then having the players comply with this mission. Training was based upon coaches' characteristics, knowledge, and strategies in physical, tactical, and technical training. Competition was a continuation and testing of the training process and the coaches played an active, integral role during each component of pre-, during-, and post-competition. Athlete-centered processes related to how the coaches perceived and dealt with athletes in such areas as empowerment and personal development, and how they chose athletes whose characteristics were compatible with the team mission. Contextual factors, such as level of competition and job conditions, also altered the organization, training, and competition categories of coaching. This research shed insight on the pedagogical strategies of expert teachers in sport by demonstrating how their characteristics, knowledge, and strategies drove the other processes of coaching.

Full textAbstract:
Under ice river plume data were collected in the spring of 1988 and 1990 at the mouth of the Great Whale River, Hudson Bay, Canada. Tidal analysis of tide gauge data and predicted tides shows a phase advance and amplitude decrease of the tide under continuous landfast sea ice. Current meter and echosounder measurements, as well as temperature-salinity profiles were taken within the first 2 km off-shore of the river mouth to provide a detailed picture of the nearshore plume conditions. Stable, subcritical flow conditions were observed for most of the sampling period, with the buoyant freshwater plume maintaining a depth of about 4 m almost continuously. During spring low tide (the lowest low tide), the cross-sectional area through which the river discharge must flow decreases substantially, resulting in supercritical (Froude number $>$1) conditions over some periods and the formation of an internal hydraulic jump.

A challenge when working with optics systems is identifying and locating errors and irregularities in an effective and non-time consuming manner. Getting a view of how light interacts with every individual component in a complex optical system would streamline this process. This report examines the 1D-LiDAR as a tool to use when troubleshooting optical systems. With a 1D-LiDAR setup, different scenarios of applications are investigated and possibilities as well as limitations are discussed. Experiments done on different optical setups show that alignment of optical elements play a key part of getting reliable information about optical systems. It is shown that the resolution of the LiDAR setup is nine millimeters but is dependent on the equipment used. Results show that with free access to a complex optical setup, it is possible to distinguish all elements in the system and their characteristics. Therefore it appears possible to diagnose defect optical elements. It is also shown that the LiDAR can be used to investigate temperature change in optical fibers.

Nineteen bovine muscles were removed from beef carcasses (n = 9). Muscles were trimmed free of fat, cut into 2.54 cm thick steaks, and were packaged in Styrofoam trays with polyvinylchloride overwrap. Steaks were assigned randomly to a day of retail display (0-, 1-, 2-, 3-, 4-, or 5-d). Steaks were evaluated over the course of retail display for objective measures of discoloration (metmyoglobin, oxymyoglobin, L*-, a*-, and b*-values), reducing ability (metmyoglobin reductase activity, resistance to induced metmyoglobin formation, and nitric oxide metmyoglobin reducing ability), oxygen consumption rate, oxygen penetration depth, myoglobin content, oxidative rancidity, and pH. Muscles were grouped according to objective color measures of discoloration. M. longissimus lumborum, M. longissimus thoracis, M. semitendinosus, and M. tensor fasciae latae were grouped as "high" color stability muscles, M. semimembranosus, M. rectus femoris, and M. vastus lateralis were grouped as "moderate" color stability
muscles, M. trapezius, M. gluteus medius, and M. latissimus dorsi were grouped as "intermediate" color stability muscles, M. triceps brachi - long head, M. biceps femoris,
M. pectoralis profundus, M. adductor, M. triceps brachi - lateral head, and M. serratus ventralis were grouped as "low" color stability muscles, and M. supraspinatus, M. infraspinatus, and M. psoas major were grouped as "very low" color stability muscles. Generally, muscles of high color stability had high resistance to induced metmyoglobin formation, nitric oxide reducing ability, and oxygen penetration depth and possessed low oxygen consumption rates, myoglobin content, and oxidative rancidity. In contrast, muscles of low color stability had high metmyoglobin reductase activity, oxygen consumption rates, myoglobin content, and oxidative rancidity and low resistance to induced metmyoglobin formation, nitric oxide metmyoglobin reducing ability, and oxygen penetration depth. Data indicate that discoloration differences between muscles are related to the amount of reducing activity relative to the oxygen consumption rate.

Full textAbstract:
Experiments examined soot generated from atmospheric pressure ethylene/air laminar diffusion flames. Without ferrocene addition, pure soot particles were collected. Addition of controlled quantities of ferrocene produced particles containing both iron and soot with iron contents up to 15%. The physical and chemical characteristics of the samples were characterized using a scanning mobility particle sizer (SMPS), X-ray fluorescence spectroscopy (XRF), and carbon aerosol analysis. Results indicated that iron addition caused a substantial reduction in the soot aerosol mass emissions and a notable modification of the particle size distribution when the flame was stable. Carbon aerosol analysis revealed an increase in the organic carbon fraction in the iron-soot particles when compared to the soot only particles or to a physical mixture of soot and commercially purchase γ-Fe2O3. Corresponding toxicological experiments involving intratracheal instillation of particles in mice examined indicators of pulmonary inflammation and induced allergic asthma-like responses to samples composed of soot only, soot-iron additive composites, and physical mixtures of soot and commercially purchased gamma-Fe2O3 nano-particles. The soot only samples overall induced the greatest inflammatory response at a time point of 4 hours post-instillation. The levels of pro-inflammatory cytokines, interleukin-6, macrophage inflammatory protein-2, and tumor necrosis factor-α showed trends of increase as the amount of carbon, not iron, in the samples increased. The results suggest that the toxicity of ultrafine particles, such as though from diesel engines or coal combustion, is correlated to the carbon content of the particles, rather than their transition metal content. Future work should examine the effects of other transition metals such as platinum and cerium in conjunction with carbonaceous particles, as well as the toxicological influence of sulfur as compared to iron in the conjunction with carbonaceous particles.

Full textAbstract:
BACKGROUND: Identifying the relationships between physical and behavioural characteristics with the presence or absence of pharmacotherapy (on or off bone medication) for postmenopausal women with low bone mass could assist healthcare professionals to individualise bone health management plans and provide better patient-centred care. Linking patient characteristics with attitudes and motivations behind their decisions would be helpful for healthcare professionals in identifying what gaps in knowledge and types of therapy patients would most likely be open to initiating, adhering to and persisting. A cross-sectional study such as this has not previously been undertaken.
METHODS: A convenience sample of 349 postmenopausal women with low bone mass were recruited from participants of the Medication and Exercise for Osteoporosis (MEDEX-OP) trial, women who were excluded from the MEDEX-OP trial and clients of The Bone Clinic in Brisbane, Australia. The baseline data from participants of the MEDEX-OP trial and the data from a routine assessment from clients of The Bone Clinic were obtained for analysis. A questionnaire requesting demographic information as well as attitudes toward medication and motivations to be on or off bone medication was emailed or sent via mail to women who had been excluded from the MEDEX-OP trial. Data was analysed via univariable and multivariable logistic regression to identify physical or behavioural characteristics related to being on or off bone medication.
RESULTS: The majority of participants were aged in their early sixties, with 256 (73.4%) off bone medication and 93 (26.6%) currently taking antiresorptive bone medication. Age in years (OR 1.05, 95% CI 1.01-1.09), two or more fragility fractures (OR 5.08, 95% CI 2.60-9.94), previously took bone medication (OR 2.48, 95% CI 1.44-4.26), fracture risk calculated as a percentage using the Garvan Institute Fracture Risk Calculator (OR 1.03, 95% CI 1.01-1.06), back extensor strength measured in kilograms (OR 0.96, 95% CI 0.93-0.98), five times sit to stand measured in seconds (OR 1.16, 95% CI 1.04-1.30), and having a promedication attitude (OR 5.95, 95% CI 2.92-12.12) or ambivalent attitude toward medication in general (OR 1.51, 95% CI 0.73-3.09) were statistically significant variables that were found to be related to being on or off bone medication following the univariable logistic regression analyses. People with ambivalent attitudes were found to be just as likely as those with anti-medication attitudes to be on bone medication. At the adjusted multivariable level, having two or more fractures (OR 3.87, 95% CI 1.53-9.79), previous bone medication (OR 2.81, 95% CI 1.36-5.78), having poor back extension strength (OR 0.95, 95% CI 0.92-0.98), and having a pro-medication attitude (OR 6.41, 95% CI 2.73-15.07) were associated with being on bone medication.
CONCLUSION: Fragility fracture history, previous use of bone medications, back extensor strength and attitudes toward medication in general were strongly related to being on or off bone medication among postmenopausal women with low bone mass. Healthcare professionals should consider these four characteristics when involving patients in the decision-making process of making a bone health management plan.Thesis (Masters)
