Abstract:

The master´s thesis deals with the design of the headstock for the horizontal boring center and design of the milling head. In the first part of the thesis, a search is made in the field of boring machines, main parts of boring machine headstock and milling heads. Based on this theoretical analysis, the input parameters for the calculation of the tension, power and torque characteristics of the headstock are selected. Subsequently, the design of the headstock and milling head is done using a 3D model.

Abstract:

The effectiveness of exercise has been increasingly studied as exercise has been popular for the improvement of physical performance and rehabilitation of lumbar spine. A variety of exercises have been used to reduce back pain or spinal degeneration. However, there are no studies to determine effects of exercise on lumbar spine kinematics, including lumbar-pelvic coordination and instantaneous axis of rotation. The current study aimed to examine these lumbar spine kinematical changes due to exercise and therapy. We hypothesized that exercise and therapy will affect the changes of lumbar spine

Abstract:

One of the most devastating effects of tetraplegia is the inability to grasp and manipulate everyday objects necessary to living an independent life. Currently surgery is widely accepted as the solution to improve hand functionality. However, surgery becomes difficult when the user has paralysed wrists as is the case with C5 tetraplegia. The aim of this research was to develop a solution which provided controlled wrist flexion and extension which, when combined with surgery, achieves a 'key pinch' grip. This particular grip is critically important for people with C5 tetraplegia as it is used f

Abstract:

Low back disorders (LBDs) comprise one of the major health issues in the United States. Previous research used isometric studies to understand the mechanisms that cause LBDs. Occupational tasks involving dynamic trunk movements, muscle fatigue, and spinal instability are identified as major risk factors for developing low back pain. Dynamic stability and muscle forces during trunk flexion-extension movements are studied in this dissertation. Torso muscle fatigue is known to affect the neuromuscular muscle recruitment that influences spinal stability. The first part of this dissertation

Abstract:

Falls from heights are the fourth leading cause of occupational injury and fatality in the United States. In particular, construction workers such as roofers are often exposed to high risk environments. Recent research has reported that a leading cause of falls among workers is a loss of balance. Therefore, in moving towards reducing the number of occupational falls, further investigation of balance and factors that influence postural control is necessary. The effect of neuromuscular fatigue has been addressed by many investigators; however, few studies have examined the effect of localize

Abstract:

Primary sensory afferent outgrowth within the developing longitudinal pathway of the spinal cord is important for intrasegmental and intersegmental communication that underlies coordination and development of reflexes and contributes to sensory perception. The endogenous mechanisms that regulate primary sensory afferent extension are the primary focus of this dissertation. This dissertation tested the hypothesis that primary sensory afferent extension in the longitudinal pathway is regulated by sphingosine 1-phosphate type 1 receptor (S1P1R) and tyrosine kinase receptor B (TrkB) through a brai

Abstract:

The netrins are a family of secreted proteins with a well characterized role in directing migrating cells and axons during embryogenesis. Netrin-1 is also expressed in the adult CNS, although its function in the adult is not known. Characterization of netrin-1 in the adult spinal cord indicated that it is expressed by neurons and oligodendrocytes and that following its secretion, netrin-1 is associated with membranes and extracellular matrix (ECM). Netrin-1 attracts or repels different cell types in the developing CNS. The repertoire of netrin receptors expressed exerts a key influence

Abstract:

La morphogenèse est le processus qui définit la forme d'un organisme (ou d'une partie d'un organisme) nécessaire à son bon fonctionnement. Au cours de l'embryogenèse, la morphogenèse d'un organe nécessite des processus incluant la division cellulaire, les mouvements cellulaires et la différenciation cellulaire. Cependant, on sait peu de choses sur la façon dont ces différents processus sont coordonnés au cours de la morphogenèse d'un organe. Au cours de ma thèse, j'ai étudié deux voies de signalisation cellulaire différentes qui régulent la morphogenèse au cours de l'embryogenèse du poisson zè

Chronic pain affects 20 % of the global population, causes suffering, is difficult to treat, and constitutes a large economic burden for society. So far, the characterization of molecular mechanisms of chronic pain-like behaviors in animal models has not translated into effective treatments. In this thesis, consisting of five studies, pain patient biofluids were analyzed with modern proteomic methods to identify biomarker candidates that can be used to improve our understanding of the pathophysiology chronic pain and lead to more effective treatments.

It has been shown that neuromuscular reflexes are elicited during spinal manipulation resulting in changes in the surrounding muscle tonicity and seen as changes in surface electromyography. Despite this little is known about the effect that SMT may have on muscle function. Increased maximum voluntary contraction

Cervical Spine injuries are a common occurrence during motor vehicle accidents, and they represent a significant economic cost to society. Numerical Finite Element (FE) models have been formulated to investigate the response of the neck under various loading scenarios and to improve vehicle safety. The Global Human Body Models Consortium (GHBMC) was formed to develop a detailed FE model capable of simulating occupant response and predicting subsequent soft tissue injuries in the cervical spine. The objective of this thesis was to validate the neck region of the GHBMC model at the segment lev

Abstract:

In this thesis, a passive exoskeleton spine was designed and evaluated by a series of biomechanics simulations. The design objectives were to reduce the human operator’s back muscle efforts and the intervertebral reaction torques during a full range sagittal plane spine flexion/extension. The biomechanics simulations were performed using the OpenSim modeling environment. To manipulate the simulations, a full body musculoskeletal model was created based on the OpenSim gait2354 and “lumbar spine” models. To support flexion and extension of the torso a “push-pull” strategy was proposed by applyin
