Optimization of pressure field in shock wave lithotripsy
ISBN: 9783639190328 / Angielski / Miękka / 212 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Shock wave lithotripsy (SWL) has revolutionized the calculus treatment, but it also produces acute renal injury. If the stone is larger than 20 mm or located in anatomically difficult locations, SWL is poor and even fails. This work aims to increase stone fragmentation while reducing simultaneously the propensity of injury in SWL. First, large intraluminal bubble expansion was found to constitute a mechanism of SWL-induced vascular injury. In situ pulse superposition technique was then developed by fitting an insert with the lithotripter reflector. It could significantly reduce the propensity...

Transcutaneous electrical spinal cord stimulation
ISBN: 9783639341546 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Spinal cord injury is a serious neurological condition. Despite its prevalence, therapeutic options are limited. Until solutions are found to cure spinal cord injury, scientists seek to improve impaired functions like standing and walking. Recently we developed a new method called transcutaneous spinal cord stimulation to electrically stimulate the spinal cord by skin electrodes. The technique is a promising approach to improve mobility of many spinal cord injured patients. In this book the theoretical aspects of transcutaneous spinal cord stimulation are elaborated by computer modeling. The...

Studies in Biological Control
ISBN: 9780521281645 / Angielski / Miękka / 322 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The best alternative to chemical control is often seen as being biological control - the introduction of natural enemies in areas where foreign pests become abundant. However, biological control alone is not always sufficient to maintain pest populations under a tolerable level; and it is necessary to learn how to make it compatible with other methods of control, and in particular with chemicals, in integrated control programs. Data on these important aspects was collected and elaborated over a period of seven to eight years and synthesized in this volume, which was originally published in...

ISBN: 9783639299731 / Angielski / Miękka / 164 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Functional electrical stimulation (FES) is a technique to artificially activate motor nerves and muscles by applying electrical current pulses to pairs of electrodes placed near the activation region. FES can be used for sports, fitness, rehabilitation, restoration of lost motor functions or muscles, e.g. in subjects with brain or spinal cord injuries. The main objective of the present work was to perform a numerical feasibility study of stimulating long term denervated muscles in the human thigh for different electrode arrangements placed on the skin surface (transcutaneous) or implanted in...

Digital Analysis of Neuronal Branching and Synaptogenesis
ISBN: 9783639358032 / Angielski / Miękka / 104 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Far from being hard-wired and static, the brain is capable of dramatic reorganization. As one learns new skills or acquire novel experiences, the brain cells alter the way in which they respond to the outside world to reflect the changing circumstances and gained experience. These changes in our behaviour and brain functions are often accompanied by structural alterations in the brain circuitry. In studies on animal brains, it has been possible to visualize very localized structural changes, such as increased branching of the dendritic trees at the ends of axons. This would allow new synapses...
