Abstract:

It is well known that maximal eccentric exercise induces muscle damage, especially when it is performed for the first time. However, muscle damage is attenuated in subsequent bouts of the same or similar exercise, which is known as the repeated bout effect. One of the factors affecting the magnitude of muscle damage and the repeated bout effect is the number of eccentric contractions; however, it is unknown if different set-repetition configurations with the same number of eccentric contractions would result in different magnitudes of muscle damage and adaptation. This study investigated chang

Abstract:

In this study, we examined how hill running affects the Achilles tendon, which is a common location for injuries in runners. Twenty females ran for 10 min on three randomly selected grades (-6%, 0%, +6%). Achilles tendon (AT) cross-sectional area (CSA) was imaged using Doppler ultrasound and peak vertical forces were analyzed using high-speed (240 Hz) videography. A metabolic cart and gas analyzer ensured a similar metabolic cost across grades. Data were analyzed using a forward selection regression. Results showed a decrease in AT CSA from pre-run to post-run (p = .0001). Peak vertical forces

Abstract:

This study explored Years 4, 6 and 8 students' understanding of the area concept. In particular, it identified and explained students' intuitive judgement rules, that is, the method by which a person integrates information about perceived stimuli when comparing area of rectangular and near-rectangular regions when no length dimensions were given. The study was based on the work of Anderson and Cuneo (1978) and the method of Information Integration Theory (IIT). IIT is a technique that classifies area judgement rules as additive, Area = Height + Width, where salient dimensions are added, or

Abstract:

Additive manufacturing involves the layer-wise patterned addition of material to create 3D parts, allowing for parts with complex geometries that traditional subtractive manufacturing processes cannot create, while offering good value for low run production parts by eliminating the cost of tooling. Large Area Sintering is a form of powder based additive manufacturing where entire layer cross sections are heated and fused in a single continuous exposure process. This layer by layer powder sintering process is similar to selective laser sintering, but by heating the cross sec

Abstract:

Cross sectional cost-allocations (COSAC) (allocation of costs to different products or objects at the same time intervals) are routine accounting procedures for most organisations. However, the purpose and decision making usefulness of COSAC remains controversial. Does COSAC have meaningful statistical purposes? If so, is there an optimal or better COSAC? Prior literature have discussed the criteria of judging different cost allocation methods under the concept of estimation of long term profitability - a concept defined as income smoothing measured by statistical variance.

To evaluate why discordance may occur between regression coefficients from cross sectional and longitudinal analyses when ventilatory function is related to ageing, a population was created by computer, and modelled to simulate functional change during life. The program incorporated the effects of many factors known to influence lung function measurements, which were adjusted experimentally so that their contributions to any discordance could be assessed. Regression analyses showed that significant discordance could be induced if the oldest birth cohort failed to reach the same maximal level o

Abstract:

This study was undertaken with the objective of determining the effect of gap distance on the weld bead geometry and the mechanical properties of the weldments. Low-alloyed and low carbon steel plates were welded under different conditions where each weldment had different gap distance and weld bead grooves. The influences of welding parameters namely, welding speed, current and voltage on the weld bead were examined in terms of weld bead penetration and heat affected zone and weld metal zone hardness variations.

Abstract:

There has been growing interest in studying the possible effects of statins on tendons due to case studies and retrospective chart reviews that reported a potential relationship between statin use and tendon pathology, as well as laboratory studies demonstrating that statins directly influence tenocyte metabolism. However, a recent epidemiological study found no association between statin use and the risk of tendon rupture. Since statins are widely used cholesterol-lowering medications, it is important to understand the potential relationship between statin use and tendon health. W

There is a general assumption that permanent teeth in children are emerging into the oral cavity earlier than the dates given in published scientific studies conducted many years ago. In the course of this research a rigorous experimental protocol was devised to provide reliable data collection and analysis methods and give contemporary emergence rate estimations with a strong scientific basis. In addition equations are presented to predict the chronological age of children using only the sex of the child and the number of permanent teeth present.

Whales were excluded from the study on the grounds that they have no nasal turbinates.

O treinamento de força de baixa intensidade com restrição parcial do fluxo sanguíneo (TFR) emergiu como uma alternativa ao treinamento de força tradicional, com intensidades variando entre moderada a alta, principalmente para idosos que possam apresentar alguma limitação ou dificuldade na realização do treinamento mais intenso. Assim, o presente estudo objetivou analisar a efetividade do TFR na modulação dos níveis de força, área de secção transversa muscular (ASTM) e dos diferentes tipos de fibra (ASTF) bem como da quantidade de células satélites (CS) e mionúcleos (MIO) presentes nas células

Abstract:

Muscle function is determined by structure and morphology at the architectural level. In response to resistance training, older adults have demonstrated that the neuromuscular system has a substantial adaptability, which may compensate for muscle size and quality and lead to improved functional capacities and higher quality of life. PURPOSE: The purpose of this study was to examine the effect of six weeks of progressive resistance exercise on muscle morphology and architecture in healthy older adults. METHODS: Twenty- five healthy men and women were randomly assigned to either six weeks of pro

Abstract:

Knowledge about biomechanical properties of veins is of importance for understanding the physiologyof the venous system. Specifically for this thesis there is a motivation based on an idea of how to usebiomechanics of the vein in the development of new non-invasive measurement techniques for assessingthe pressure in the brain. The cross sectional area of veins is known to depend on pressure changes insidethe vessel. There are many ways of provoking these pressure changes, like changing posture or creating apositive airway pressure. The hypothesis is that the positive airway pressure will incre

Abstract:

Background: Low back pain (LBP) is often associated with lumbar spinal instability (LSI). The multifidus muscle is considered a stabilizer of the spine and has been studied extensively with Rehabilitative Ultrasound Imaging (RUSI). There may be a relationshipbetween clinical signs of LSI, decreased cross-sectional area (CSA) of the multifidus and weakness. Having the ability to detect multifidus weakness without the use of RUSI may serve to be invaluable to the clinician in detecting multifidus weakness.Purpose: To investigate the relationship between the modified prone straight leg raise test
