Este objetivo é alcançado através de uma abordagem prática ao processo de pesquisa, a qual foi realizada através da criação de novas obras e a respectiva avaliação sobre o comportamento dos visitantes, processo repetido a cada etapa deste trabalho. O trabalho contempla a análise e a localização de nossas referências para os conceitos de instalações, design sonoro e interatividade. Apresentamos uma proposta para estruturação do design sonoro baseada na espectro-morfologia de Denis Smalley, utilizando este conjunto teórico como modelo para estruturar a relação entre o som e o conteúdo referencial da obra, e entre o som e o modelo interativo que se pretende abrir aos visitantes. Implementamos um conjunto de descritores de propriedades físicas para o movimento e desenvolvemos um conjunto de descritores baseados na fusão de dados sobre as propriedades físicas do movimento, com a intenção de descrever as classes de Esforço para a Análise de Movimento Laban. Estes descritores objetivam suprir deficiências do modelo interativo utilizado no início da pesquisa, durante o desenvolvimento das instalações Abstrações e Cerejeira. A instalação Caminho das águas integra os desenvolvimentos alcançados pela pesquisa: uma nova abordagem para a relação entre o projeto conceitual da obra, seu design sonoro e o modelo interativo revisado. Um extenso estudo com participantes aplicado sobre esta instalação permitiu avaliarmos os resultados alcançados a partir das hipóteses levantadas durante o desenvolvimento da pesquisa / Abstract: This thesis presents the creative process of the interactive audiovisual installations Abstrações, Cerejeira and Caminho das águas, relating them to the main objective of the research, which consists in the analysis of the models that integrate the conceptual project of each installation, its sound design and the interactive processes that model the relation between visitors and the work. This objective was achieved through a practical approach to the research process and was implemented by the designing of new installations and the respective evaluation about the behavior of visitors. This process was repeated at each step of the research. This work includes the analysis and origin of our references to the concepts of installations, sound design and interactivity. We present a proposal to structure sound design based on the spectro-morphology developed by Denis Smalley. We propose the use of this theoretical corpus as a model to structure the relation between the sound and the referential content of the work, and between the sound and the interactive model that is intended to be open for visitors' participation. We have implemented a set of descriptors to retrieve physical properties of the movement. We also developed a set of descriptors based on data fusion from these physical properties, intending to describe the classes of Effort for the Laban Movement Analysis. These descriptors aim to fulfill shortcomings observed in the interactive model adopted in the early part of the research, specifically during the development of the installations Abstrações e Cerejeira. The installation Caminho das águas integrates the developments achieved by this research: a new approach to the relation among the conceptual project of a work, its sound design and the interactive model adopted. An extensive study with participants applied over this installation enabled us to evaluate the results achieved from the hypotheses raised during the development of the research / Doutorado / Processos Criativos / Doutor em Música

Thesis (M. Sc. (Agriculture)) --University of Limpopo, 2017 / Tea is one of the most popular consumed beverages in the world, which has beneficial properties such as anti-oxidization, anti-carcinoma and preventing arteriosclerosis. The major essential components of catechins present in tea leaves, includes epigallocatechin gallate (EGCG), epigallocatechin (EGC), epicatechin gallate (ECG), epicatechin (EC), gallocatechin (GC) and catechin (C). Influence of time-based hot air drying method on chemical composition of the Jatropha zeyheri Sond, widely consumed in rural communities of Zebediela (Khureng village), Limpopo Province, South Africa, was investigated. Four treatments, namely; 0, 24, 48, and 72 hours, were arranged in completely randomised design (CRD), replicated five times. The study demonstrated that drying significantly increased total phenolic content, total antioxidant capacity and tannin content. It also demonstrated that drying significantly increased minerals elements; Mg, K, P, S, Al, Co, Mn, Si and Zn content and decreased Na, Ca and Ni and Zn quantities. Sodium-potassium ratio was very low across drying periods. Drying time did not significantly influence proximate chemicals; energy, protein, carbohydrates, ash and fibre content. Moisture and fat were significantly increased by drying period. Results of the study suggested that time-based hot air drying method improved the chemical composition of J. zeyheri, which has the potential of enhancing nutrition in marginal rural communities of Limpopo Province.

"The purposes of this study are: I. To survey, through the questionnaire method and through the examination of the literature in the field, the general practice of using student operators of audio-visual equipment. II. To determine the best method of using students as projectionists in relationship to the student as well as the service rendered the school. III. To produce a projectionist's manual for the use of students training to operate audio-visual equipment. It is realized that there are on the market several audio-visual operator's manuals; also those produced by commercial concerns to accompany various pieces of equipment, but through personal experience and the experience of others the writer feels that all of these manuals are too technical for use by elementary and high school students. Therefore the primary purpose of this study is to produce such a manual"--Introduction. / Typescript. / "March, 1949." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements for the degree of Master of Arts under Plan II." / Advisor: Louis Shores, Professor Directing Paper. / Includes bibliographical references (leaves 39-41).

Thesis (MPH.) -- University of Limpopo, 2021 / The purpose of the study was to assess the knowledge and practice of personal protective equipment amongst the employees at Laundromats in Seshego industrial site, Limpopo province. A quantitative research study was conducted using a questionnaire to gather information from employees who were working at Laundromats and possibly exposed to occupational injuries and diseases. Fifty-two employees responded to the questionnaires. The findings revealed that employees showed good knowledge (81%) about personal protective equipment but poor practice (52%) of personal protective equipment. The findings also revealed that the majority of employees (75%) did not receive training because it was not offered. Conclusion Majority of employees had good knowledge. There was an appropriate response to the majority of questions relating to knowledge about PPE. However, majority of employees had poor practice of PPE. The lack of training might have led to poor practice. Key concepts: Knowledge, Practice and Personal Protective Equipment.

This study correlated the performance accuracy of peripheral blood differentials evaluated by clinical laboratory scientists and clinical laboratory technicians. Fifty-one senior-year students from four clinical laboratory science baccalaureate programs and 37 second-year students from five clinical laboratory technician programs were given 10 peripheral blood differentials to perform. Results were compared to the values assigned by the Rajamaki method of proficiency testing. There was a significant discrepancy in the levels of accuracy between the two cohorts, suggesting that the results of peripheral blood differentials performed by clinical laboratory technicians is suspect. Facilities wishing to maintain or improve the quality of laboratory services should consider allowing only baccalaureate level clinical laboratory scientists to perform peripheral blood differentials.

The use of knee braces in the past has been to protect and prevent further injury to a previously damaged knee. An Example of one such knee brace is the Lennox-Hill Derotation knee brace. This brace is used to assist the athlete who has a rotatory knee instability from a previous injury. (Klafs and Arnheim, 1977.) The problem of this study is to determine the possible effects of the Anderson Knee Stabler on mean isometric torque output in the knee extensor, mean isokinetic torque output at several speeds in the knee extensors and performance on the SEMO Agility Test in college football This study is important because it will assess the functional capability of an athlete wearing this given brace. Also, if significant differences are not achieved it will serve as a means of promoting this brace to those who may be reluctant to use it. If significant results are achieved then athletic trainers and coaches may have to rethink whether this brace is impairing the performance of their athletes.
