In the normal, healthy individual the acid-base balance within the body is remarkably constant. For example, arterial blood, drawn from healthy individuals at sea level, will show that, in over 95% of the individuals, the pH of the blood is between 7.35 and 7.45. Furthermore, the pC02 will be maintained between 35 and 48 mmHg while the bicarbonate concentration will be between 23 and 28 mEq/L. ...

INTRODUCTION Large villous adenomas or adenocarcinomas of the rectum can determine secretory diarrhea, associated with a depleting syndrome of prerenal acute renal failure, hyponatremia, hypokalemia, and hypoproteinemia, with favorable prognosis if early detected and properly treated. The syndrome is rare, with approximately 50 cases reported in the literature. AIM Acute renal failure, caused...

Adjustments of respiration and circulation in response to alterations in the levels of oxygen, carbon dioxide and hydrogen ions in the body fluids are mediated by two distinct chemoreceptive elements, situated peripherally and centrally. The peripheral arterial chemoreceptors, located in the carotid and aortic bodies, are supplied with sensory fibres coursing in the sinus and aortic nerves, and...

This thesis considers the control of a heavy-lift serial manipulator operating on the deck of a large ocean vessel. This application presents a unique challenge for highprecision control because the system must contend with both high levels of joint friction and oscillatory motions in the manipulator's base. Due to the uncontrolled outdoor environment, the behavior of these disturbances in the ...
