Professional nurses working in an intensive care unit (ICU) are faced with the death of critically ill patients frequently. Modern day medicine and technology have made it possible for advanced life-sustaining measures to be implemented on patients who, without medical intervention, would otherwise not have survived. The question is raised: is modern technology preserving life and prolonging the dying process, or is it in the best interest of the patient for treatment to be withdrawn? Nurses, caring for these patients and their families, are practicing at the bedside of these dying patients and are thus often faced with end-of-life issues, particularly withdrawal of treatment. The primary functions of critical care nurses are toward their patients. Physicians are responsible for making decisions regarding withdrawal of treatment. However, the nurses in the ICU are responsible for implementing the decisions made; sometimes contradicting what they believe in. The experience of end-of-life issues, namely withdrawal of treatment, is a cause of distress for the professional nurse. Little research has been done on how the ICU nurses deal with end-of-life issues and what support structures are required to assist nurses in dealing with end-of-life issues (Hov, Hedelin & Athlin, 2006:204) The objectives of the study were to explore and describe the professional nurses‟ lived experiences of end-of-life issues in the intensive care unit. The study aimed to make recommendations regarding support strategies to assist professional nurses in dealing with end-of-life issues in the intensive care unit. The researcher has selected a qualitative research approach with an explorative, descriptive and contextual design in order to conduct the study. Data was collected by means of semi-structured interviews. Data was analysed using the steps as illustrated by Tesch‟s method. Ethical principles were maintained throughout the research study. The findings of this study are to be presented in a journal publication.

Sorting is often computationally intensive and can cause the application in which it is used to run slowly. To date, the quickest software sorting implementations for an N element sorting problem runs at O(nlogn). Current techniques, beyond developing better algorithms, used to accelerate sorting include the use of multiple processors or moving the sorting operation to a GPU. The use of multiple processors or a GPU can lead to increased energy consumption and heat produced by the device as compared to a single-core GPU-less implementation. To address these problems, specialized instructions and hardware units can be added to the processors to accelerate the sorting operation directly. This thesis studies and records the performance implications from implementing a sorting accelerator into a modern RISC-V processor pipeline. This thesis also explores the additional energy and area costs of implementing such hardware units in the processor.
