    Facing a rapidly-changing power industry, the electrical engineering department at Cal Poly San Luis Obispo proposed Advanced Power Systems Initiatives to better prepare its students for entering the power industry. These initiatives call for the creation of a new laboratory curriculum that utilizes microprocessor-based relays to reinforce the fundamental concepts of power system protection. The electric power protection laboratory (EPPL) senior project is the validation of lab manuals written for the planned EE-518 power system protections laboratory looking to be offered in Spring 2020 alongside the current lecture class under the same designation. This report evaluates the lab manual, verifies SEL relay settings, updates experiment requirements and resources, and provides feedback on improving the coursework. The microgrid integrates photovoltaics, real time simulation, and power system protection devices ensuring the future EE 518 laboratory will provide hands-on experience with power system components and operation. The experiments expose students to the capabilities of industry-standard microprocessor-based relays through hands-on procedures that demonstrate common power system protection schemes. Relays studied in this project support transformer, transmission line, and induction motor protection. This senior project and the Cal Poly microgrid project as a whole was created as an initiative by the power engineering faculty and electrical engineering department to provide additional lab course for students concentrating in power engineering

    Culture, Risk, and the Prospect of Genetically Modified Organisms as Viewed by Tāngata Whenua

    126 pages“Risk analysis is both a scientific and a political exercise. Ultimately the whole exercise is driven by values, which determine choices made even within science, and the choices made by decision-makers and by society at large.”1 Few issues better characterize the social, scientific, and political dimensions of the late 20th and nascent 21st centuries than do debates about genetic engineering. Faced with growing public anxiety about such research, particularly that concerning genetically modified organisms (GMOs) and their possible release into the environment, the New Zealand Government has sought to address these concerns in two important ways. First was the commencement of a Royal Commission of inquiry into Genetic Modification. The Commission presented its findings in July 2001.2 The Government has also funded several research projects through the Foundation for Research, Science and Technology, which investigates this technology, including the social, cultural, and economic milieu in which this research is being conducted in New Zealand

    Whakapapa as a Maori Mental Construct: Some Implications for the Debate over Genetic Modification of Organisms

    The use of whakapapa by New Zealand MĂ€ori is most commonly understood in reference to human descent lines and relationships, where it functions as a family tree or genealogy. But it also refers to an epistemological framework in which perceived patterns and relationships in nature are located. These nonhuman whakapapa contain information concerning an organism’s theorized origins from supernatural beings, inferred descent lines, and morphological and ecological relationships. In this context whakapapa appear to function at one level as a “folk taxonomy,” in which morphology, utility, and cultural considerations all play an important role. Such whakapapa also function as ecosystem maps of culturally important resources. More information and meaning is provided by accompanying narratives, which contain explanations for why things came to be the way they are, as well as moral guidelines for correct conduct. Renewed interest in the whakapapa of plants and animals has arisen from concerns raised by MĂ€ori in regard to genetic modification, particularly the transfer of genes between different species, as this concept is frequently invoked by those who oppose transgenic biotechnology. Informed dialogue on this subject requires an understanding of the structure and function of nonhuman as well as human whakapapa and their underlying rationale, as well as the nature of the relationships among the things included in nonhuman whakapapa. Of additional interest and relevance is the relationship of whakapapa to modern scientific concepts of taxonomy based on phylogeny and the species concept. In this paper we describe and interpret the whakapapa of an important food plant, the sweet potato or kümara, in terms of its apparent functions and underlying rationale. We also discuss how the whakapapa and its associated narratives might contribute to the current debate on genetically modified organisms in New Zealand

    Methods in cattle physiology and behaviour research : Recommendations from the SmartCow consortium

    No full text
    This book provides an inventory of guidelines for different recordings in an experimental unit. The chapters of this book will encompass methods that deal with measuring different metabolic, digestive, anatomic and behavioural traits in cattle. The experimental methods have been divided into two main categories:a) routine measurements, conducted in different research infrastructures, e.g. daily feed or water intake of cattle, heat detection, body condition scoring and back-fat thickness measurement;b) specific recordings, using particular methods, such as: estimating passage rate of digesta, respiratory chamber and/or nitrogen balance experiment.Wherever possible, the authors sought to include the most recently established, innovative and non-intrusive tools/systems for each of the enlisted methods
