Potential for Chemical Repellents Against the Mite Tyrophagus putrescentiae to Prevent Infestation of Country Hams

Tyrophagus putrescentiae (Shrank), commonly known as the ham mite, is a cosmopolitan pest found of various stored food commodities, including aged hams and cheeses (Amoah et al. 2017; Campbell et al. 2017). Recent research suggested methods to deter T. putrescentiae from infestation of country hams using different types of food-safe chemicals (Abbar et al. 2016). In this experiment, four chemicals were tested to ascertain their effectiveness in deterring T. putrescentiae from ham infestation. Repellency tests used a piece of ham and a group of mites placed on opposite sides of a Petri dish with a black construction paper floor. A test barrier of a test compound or solvent control was deposited on a white filter paper strip bisecting the dish at its center. The chemicals Nootkatone, Propylene Glycol, Glycerol and a fatty acid blend called “C8910” prevented more mites from contacting the ham compared to strips with solvent. These results suggest the potential for using one or more of these food-safe compounds to prevent ham mites form infesting hams in aging rooms

The role of energy storage systems in meeting ramp rate requirements for multiple generators

In the global push towards decarbonization, no sector has seen as resounding success than the power sector. The last 22 years have seen successive record-breaking additions to the global installed capacity of renewable energy generation. Wind and solar energy have seen dramatic advancements in technology and reductions in cost, and are now some of the most cost-effective form soft power generation on the market. Over the upcoming years the goal of an electrical grid dominated by renewable energy sources is predicted to become a reality. The shift away from traditional forms of power generation is not without its risks, however, and the promotion of grid stability in the face of an influx of variable and intermittent generators is increasingly important. Both wind and solar generation are, by the nature of their production, proneto sudden and significant changes in power output, which can have deleterious effects on the health of the electrical grid. The mitigation of these fluctuations of power, known as ramp rates, is an ongoing area of study in the energy engineering industry. One common solution is the use of energy storage systems (ESS) to ’smooth’ the power sent to the grid by charging or discharging during periods of high variability. Energy storage technology however still comes at a high cost, and for the integration of renewable energy to remain cost-competitive, it is necessary to explore how to lower the price of ramp rate enforcement. This thesis investigates the sizing and use of ESS in the enforcement of a set ramp rate limit for a grid system with multiple renewable energy generators. This study is based on the fact that the ramping behaviors of a series of generators will be different depending on where in the system the ramp rate is enforced, and so ESS storage, power and cost should be optimized to the architecture of the grid. Described within is the creation of an optimization model for the sizing of energy storage systems for the purpose of enforcing a ramp rate limit. Two case studies are developed, describing two possible use cases of energy storage in a grid with multiple renewable energy generators: with the ESS located at the substation and with the ESS co-located with generators. The optimization model is run for each of the case studies through several sets of model parameters, until a final set is defined. The final results are analysed for ESS installed capacities, dispatch and costs. Ananalysis of the final results returns a stark difference between the two case studies. By amalgamating the power flows from the four generators a significant amount of ramping violations were mitigated, and the centralized ESS was conservatively used throughout the modeled period. A lithium ion battery with a discharge rate of 1C is recommended to be located a the substation. The co-located units, compensating for a single generator each, underwent significantly higher amounts of dispatch and as such high cycle-life flywheels are recommended for this architecture. Overall the centralized architecture was shown to be a much more efficient method of ramp rate control, discharging a tenth of the energy than the total of the co-located storage systems for the same ramping performance. However additional considerations such local stability conditions and asset ownership must be considered before a recommendation can be made

Analysis of the Economic Development of Statesboro, Georgia’s Blue Mile: A Structural Approach for Diversification

The Blue Mile has become a center for Statesboro’s Economic Development plan of business diversification and downtown revitalization. Downtown revitalization is important not only to existing businesses but also to expanding the property tax base. The gauging of revitalization and diversification in the field of community development has been overlooked in favor of qualitative generalizations. Burayidi’s Scorecard is used as a basis to establish a standard for the structural analysis tests conducted to measure business diversification

Music as Art: A Study of Expressing Emotion Through Music and Art

People have been expressing emotion with different art forms throughout history. Emotion has always been something that is hard for us to explain with words, so we have turned to painting, drawing, dancing, and music to add a visual or auditory explanation to what we feel. Depending on the chords or colors that are used, music and art can evoke specific emotions. There are many similarities between art and music, especially in the terms used to describe it. Both artists and musicians refer to their work as “compositions” and “pieces.” The musical term “timbre” means tone color and refers to the color provided by different instrument voices that make up an orchestration. Both art and music use motifs, themes, texture, and harmony. A common way that composers and directors will describe how they want a band to sound is by using the world “color.” Then the question becomes, “what color?” Of course, it is just an expression and a word to describe tone quality, but some artists have taken what they hear musically and they have translated it into an expression of color and shapes

Raising Māori Student Achievement - Journeys of Success

Educational success for Māori students is influenced by confidence in one’s identity, positive role models and support; and positive attitudes to learning and success. This project asked Māori tertiary graduates about their educational experiences. Half of the participants in this study had successfully completed secondary school and the other half did not complete secondary school education. This selection of participants was selected to highlight that although some students don’t complete secondary school it is still possible to successfully pursue and complete tertiary level qualifications. The feedback given from the participants highlighted the positive factors that influenced their successful completion. From these factors recommendations have been developed to support Māori student success. The objective of this study is to encourage the development of increased self-confidence for Māori rangatahi and to promote the continuation of lifelong learning. When Māori students are supported both at school and in the home they are more likely to achieve educational success, particularly at secondary school level. Similarly, at tertiary level study; students who graduate with a completed degree qualification are likely to have had positive support and successful role models, they are likely to be secure within their own identity and wh!nau network. Māori students that successfully complete tertiary study are more likely to have positive attitudes to learning and to achieving; knowing how to access support and feeling confident in their efforts. The key to this study is the link between successful completion of secondary school and the follow-on to successful tertiary study. When Māori students are supported appropriately in the development of their identity their confidence soon follows. This support would ideally come from wh!nau in the home and the school. When Māori students are confident in their learning journeys through high levels of confidence in identity they are more likely to persevere under pressure and despite setbacks. Influencing factors to developing self-confidence for Māori students include awareness of Te Reo Māori and Tikanga Māori, responsibility at home, responsibility at school and the positive influence of role models. The study then concludes by providing recommendations for learners, educators and wh!nau to support the educational achievement of their tamariki

A Community Centered by Love: A Linguistic Approach to the Theology of Paul\u27s Instruction for the Corinthian Body

This article appropriates elements of M.A.K. Halliday’s Systemic Functional Linguistics (SFL) to analyze the Apostle Paul’s communication with the Corinthian church in 1 Corinthians 12-14. The linguistic evidence of the text reveals that Paul’s instructions guide the Corinthians to order their community through love, imitating the Trinity’s nature of diversity and unity. The final section translates Paul’s teachings to a modern context using Richard B. Steele’s article, “Disability and the Beloved Community,” a reframing of how Christian communities interact with and not only include persons with disabilities but fully incorporate their diverse gifts into the church body

LV Debt Collect v. Bank of N.Y. Mellon, 139 Nev. Adv. Op. 25 (Aug. 24, 2023)

The Nevada Supreme Court affirmed the district court’s grant of summary judgment in a quiet title action disputing the ownership of real property. The Court held that, for the purposes of NRS 106.240, a Notice of Default is not sufficient to make a secured debt wholly due for the following reasons: (1) the plain language of the statute requires an interpretation of whether a debt is wholly due according to the original terms and any extensions, (2) state law requires a waiting period after a Notice of Default has been recorded before the debt can be accelerated, and accelerations of a debt must be clear and unequivocal, and (3) policy reasons behind the statute do not support its application to Notices of Default

B.Y. and A.F. v. Dist. Ct., 140 Nev. Adv. Op. 32 (Apr. 25, 2024)

In a per curium opinion, the Nevada Supreme Court found an abuse of discretion in the lower court’s denial of an ex parte temporary guardianship petition. The considerations outlined in NRS 159A were not met, therefore, the lower court improperly denied the petition. NRS 159A.053(4) presumes that petitions for guardianship are in the best interest of the child under certain conditions. This presumption is rebuttable at any time, but an ex parte motion need not be denied merely because an opponent cannot rebut it before a decision is rendered. Further, NRS 159A.053(3) requires that an affidavit describing the emergency supports an ex parte petition for temporary guardianship. The lower court’s evaluation of the emergency here improperly relied on a misunderstanding of who filed the petition. For these reasons, the Court granted the petition for a writ of mandamus in part to reconsider the original petition for temporary guardianship
