Ghost Limb
This thesis, submitted as part of an M.A in Creative Writing, takes the form of a novel set in a small coastal town outside Cape Town and follows the life of Johanna, a maid to a pastor's family in the early 90s. At the centre of the novel is the relationship between Johanna and a first-person …

Fgf4 and Wnt5a/Pcp Signaling Promote Limb Outgrowth by Polarizing Limb Mesenchyme
… growth factors (FGFs) mediate outgrowth of the limb. Specifically, we examined the epistatic relationship between FGF and Wnt/Planar cell polarity (PCP) signaling in establishing cell polarity as a mechanism for outgrowth. By implanting beads into embryonic limbs and lateral plate mesoderm, we …

Investigating the Influence of Upper Limb Movements on Lower Limb Neuroplasticity in Humans
… dissertation investigates the influence of upper limb (UL) movements on lower limb (LL) neuroplasticity in humans, with a focus on both healthy individuals and those with chronic stroke. Using neurophysiological tools to assess spinal and cortical excitability, the studies examined whether UL …

Effect of Unilateral Lower-Limb Amputation on Intact Limb Biomechanics: A Systematic Review
… have explored the effects of the affected limb and prosthetic intervention yet have neglected that of the contralateral limb (De Asha et al., 2014; Jones et al., 2006; Winter & Sienko, 1988). Studies have reported an increase in secondary musculoskeletal conditions among unilateral …

Dynamic Air Exchange Prosthesis: Effects on Heat Transfer and Limb Adherence for Active Lower Limb Amputees
Lower limb amputees are often dissatisfied with the comfort of their prosthesis. A literature review of 38 selected studies revealed that more than 53% of people with amputation experienced heat and/or perspiration discomfort inside their prostheses. Current prosthetic liners are usually made from …

Mammalian limb morphology: the role of the crawl in determining marsupial limb integration, development, and evolution
… birth has constrained the evolution of the forelimb and the group as a whole. However, the hind limb, which does not participate in the crawl, may have “escaped” the crawl’s constraint. This strong selective pressure to develop the forelimb early has also led to a decrease in integration (i.e. …

When Suddenly the Limb Did Quiver
… in my thesis exhibition When Suddenly the Limb Did Quiver, where the gallery serves as a creative space that enables some potential manifestations of this artistic practice to emerge.

Lower limb muscle function during cycling.
… was to describe the functional role of the lower limb musculature during stationary cycling using electromyography, muscle-tendon unit length changes, and segmental kinematics. Five subjects were filmed (100 Hz) in synchrony with the collection of LE EMG activity of the gluteus maximus, …

Mechanism of Lmx1b-regulated Limb Dorsalization
… transcription factor is necessary for limb, kidney, eye, and central nervous system development. Lmx1b knockout (KO) mice display; abnormal limb dorsalization with distal ventral-ventral limbs, nephropathy, ocular malformations, loss of dopaminergic/serotonergic neurons, and reduced …

Amending Limb Movements to Mechanical Disturbances
Three experiments were designed to answer a number of questions concerning the nature of proprioceptive error correction in the control of voluntary motor responses. Experiment 1 attempted to operationally determine the relationship between two theoretically described types of movement errors,

Advanced Prototypes of the Aerosol Limb Imager
… development to address this call. The Aerosol Limb Imager, or ALI, is a candidate remote sensing instrument that will provide this monitoring. ALI is a Canadian developed atmospheric remote sensing instrument specifically designed to be sensitive to aerosol and clouds from the mid-troposphere …

Machine Learning for Predicting Prosthetic Limb Movements
… prediction model capable of identifying intended limb movement from surfaced electromyography (sEMG) signals using sequence learning techniques. sEMG signals change over time due to multiple factors such as muscle fatigue or user variability. Traditional prosthetics control methods rely on static …

Studies in Amphibian Limb Development and Regeneration
… to investigate the phenomenon of amphibian limb regeneration. However, these past experiments have not attempted to apply rigorous statistical methods to analyze specific whole limb and regeneration blastema events. The most interesting of these events are those that occur during the …

Upper limb ischaemia : a twelve year experience
Introduction: Upper limb ischaemia (ULI) is a relatively uncommon, but well recognized vascular entity. The sequalae of impaired function or amputation of an arm can be devastating to the individual with loss of independence and / or livelihood. There remains much to be learned that can only be …

Giraffa camelopardalis: limb bone histology through ontogeny
… the microanatomy and histology of giraffe limb bones through ontogeny. Mid-diaphyseal sections of humeri, radii, metacarpals, femora, and tibiae of 14 individuals representing individuals of known sex, as well as at different ontogenetic stages (foetal, juveniles, subadults, and adults). …

Impact of Sex and Stretch-Shortening Cycle Induced-Fatigue on Limb Stiffness and Limb Stiffness Asymmetry During the Stop-Jump
… induced by the stretch-shortening cycle on lower limb mechanics and asymmetry values in the stop-jump task. The first purpose of the study was to assess the effect of sex and stretch-shortening cycle fatigue on limb stiffness and limb stiffness asymmetry. The second purpose was to assess landing …

Design and control of powered lower limb prostheses
In the development of powered lower-limb prostheses, providing sufficient power and torque to support amputees’ locomotion is a major challenge, considering prostheses’ weight and size limits. Furthermore, regulating the power delivery during locomotion is equally important that gives amputees safe …
