Techno-Economic Analysis Of Protein Concentrate Produced By Flash Hydrolysis Of Microalgae, Alexander Nana Yaw Asiedu Oct 2015

Techno-Economic Analysis Of Protein Concentrate Produced By Flash Hydrolysis Of Microalgae, Alexander Nana Yaw Asiedu

Civil & Environmental Engineering Theses & Dissertations

Process simulation and techno-economic analysis of 95wt.% protein concentrate from microalgae has been performed using SuperPro Designer v. 9.0. This work, first of its kind, is focused on the economic analysis of protein concentrate that includes processes such as microalgae cultivation, harvesting, protein extraction and drying steps. A baseline capacity of 160 MT/day protein concentrate production on commercial basis has been analyzed. This throughput requires 336 MT/day dry algae (54 wt.% protein). The amount of carbon dioxide required to grow this quantum of algae is estimated to be 648 MT/day, which is produced from an in situ 21 MW power …


A Study Of A Simulated Infectious Disease On Healthcare Workers' Reaction, Knowledge, Attitudes, And Performance Towards Hand Hygiene, Lydia Wigglesworth-Ballard Jul 2015

A Study Of A Simulated Infectious Disease On Healthcare Workers' Reaction, Knowledge, Attitudes, And Performance Towards Hand Hygiene, Lydia Wigglesworth-Ballard

Health Services Research Dissertations

Problem Statement. The high rate of healthcare worker-patient contact provides many opportunities for exposure to pathogens, which creates challenges in assessing healthcare workers' success at preventing healthcare associated infections caused by these dangerous pathogens.

Methods. This study explored the effects of a simulated infectious disease on healthcare workers' hand hygiene knowledge, attitudes, performance, and reactions using Kirkpatrick's Four levels of Evaluation. The study utilized a mixed method pre-test – 2 post-test design. The dependent variables were hand hygiene knowledge, attitudes toward hand hygiene guidelines, hand hygiene performance, and reaction to the overall experience. Data was collected three times over a …


Effect Of An Adaptive Thinking Training Methodology On Critical Thinking Disposition Using Human Patient Simulators: A Catalyst For Preparing Advanced Nursing Students, Robert Joseph Fitkin Jr. Apr 2015

Effect Of An Adaptive Thinking Training Methodology On Critical Thinking Disposition Using Human Patient Simulators: A Catalyst For Preparing Advanced Nursing Students, Robert Joseph Fitkin Jr.

Teaching & Learning Theses & Dissertations

Critical thinking decision making is the foundation for effective, safe, nursing practice. Nurses have to assess patient issues rapidly regardless of whether it is emotional, psychological, or physical, and then sort through "rapid fire" questions resulting in invisible sorting, discerning, and drawing of conclusions. Doing this "invisible sorting" well requires practice. Nursing education provides practice through preceptors or scenarios-driven human patient simulators to practice critical thinking. This study examines Adaptive Thinking Training Methodology with simulation exercises as a possible catalyst for growth in critical thinking disposition, and help in addressing the preparation-practice gap for novice nurses.

A class of advanced …


Toward A Theory Of Multi-Method Modeling And Simulation Approach, Mariusz A. Balaban Apr 2015

Toward A Theory Of Multi-Method Modeling And Simulation Approach, Mariusz A. Balaban

Computational Modeling & Simulation Engineering Theses & Dissertations

The representation via simulation models can easily lead to simulation models too simple for their intended purpose, or with too much detail, making them hard to understand. This problem is related to limitations of the modeling and simulation methods. A multi-method Modeling and Simulation (M&S) approach has the potential for improved representation by taking advantage of methods' strengths and mitigating their weaknesses. Despite a high appeal for using multiple M&S methods, several related problems should be addressed first. The current level of theoretical, methodological, and pragmatic knowledge related to a multi-method M&S approach is limited. It is problematic that there …
