No full textA Comparative Study of Specific Enthalpy of Aromatic Hydrocarbons with Simple Carbohydrates
No full textCalorimetry is an aspect of chemistry primarily focused on determining the enthalpy of reactions (∆Hrxn). In the bomb calorimetry technique, the heat of combustion of chemical compounds can be measured experimentally. From this data and the application of Hess’s Law, ∆the Hrxn of several chemical reactions can be determined. The technique of bomb calorimetry can be applied to food, fuels, pharmaceuticals, and many other fields. The objective of the present project is to determine the specific enthalpy of various simple carbohydrates (naturally occurring sugars) through bomb calorimetry and compare it with that of aromatic hydrocarbons.
By performing benzoic acid standardization reactions with the Parr™ Model 1341 Oxygen Combustion Vessel, the calorimeter constant was found to be 10.2717 ± .0565 KJ/°C with a 95% confidence interval, allowing the accurate determination of specific enthalpy for each of the sugars at constant volume in a pure O2 vessel.
As we proceed with the experiment several aromatic hydrocarbons (e.g Naphthalene, etc) and several simple carbohydrates (e.g Sucrose, Glucose, etc.) will be tested to obtain the enthalpy of combustion (∆Hcomb). We will perform quantum chemical calculations on the reactant and product molecules to determine the ∆Hcomb and compare the experimental values with computational data

A Phenomenological Examination of the Lived Experiences of African American Female Superintendents in the State of Arkansas
Get PDFAbstract
The purpose of this qualitative study was to examine the lived experiences of African American female Superintendents in the State of Arkansas. One of the major educational issues is the limited number of African American female superintendents in the USA and the state of Arkansas, in particular. African American women venturing into the superintendency are hindered in their goals by their double minority status as women and African Americans (Wiley et al., 2017). A qualitative, narrative research lens was used in this study to capture the individual career advancement of African American female Superintendents in the State of Arkansas. Data collection centered on personal, one-on-one interviews with African American female Superintendents in the State of Arkansas. The primary and guiding research questions for this study were focused on the women backgrounds, experiences, and educational paths that led to their superintendent position. A series of common themes emerged from the interviews and produced a clear understanding of the path the female superintendents traveled to assume the most important decision-making role in their respective school districts. Key themes which emerged were leadership ability, leadership desire, and mentorship. Participants indicated they had developed a keen sense of self-efficacy, which led to broader goals and career advancements. In future research, it is important to analyze opportunities women have which help shape, encourage, and support other African American women moving into the role of Superintendent in the State of Arkansas.

Helping with Classroom Management by Using a Timer.
No full textResearch Question: Would giving students a set amount of time on a question help them focus on their work?
I conducted my research by displaying a digital timer on the teachers smartboard. The timer was used during the students\u27 Bell Ringer to keep them engaged in their work. The students were given 5 minutes to complete their Bell Ringer.
During the time of conducting my research students were given a project over animal extinction (Zoo Exhibit). The first day that the timer was displayed in the classroom was during the Bell Ringer that asked students to find an animal that was on the verge of extinction. The students had 5 minutes to look through a list of animals that interested them. Once the timer was done, students then had to tell the teacher what they would be doing their research project over. The Bell Ringer helped students get a good start on their project, and the timer helped the students focus on the assignment.
The next day, the Bell Ringer was a 3, 2, 1 notes that asked students questions regarding their research project. The students were given 5 minutes to complete their notes which helped them stay focused on their work. By allowing students to complete this Bell Ringer assignment, it helped the students refresh their minds over the types of information that they found the day before.
By giving the students a timer on the board, it helped the students take responsibility in completing their assignments. The timer was a great success at reducing talking, distractions, and unfinished work. Students were more engaged in completing their assignments than before displaying the timer. The teacher that I was observing also said that the timer was a great success in her classroom
Weber\u27s Clarinet Concertino Opus 26
No full textAs a professional musician, it is important that one does not simply learn the notes and rhythms in a piece of music, but also the history surrounding it and its composer. There is much to learn about a piece of music and how it may be performed from original scores, performance history, and knowledge of the composer and the time period in which it was written. This lecture recital aims to open eyes to the amount of relevant knowledge one can gain from researching a piece of music’s composer, setting, and the importance of doing this research. This presentation will include a lecture on the history of the composer, Carl Maria von Weber, the clarinetist for whom his Clarinet Concertino Op. 26 was written, Heinrich Baermann, as well as the time period and culture surrounding it and its success in performance. This knowledge is drawn from Pamela Weston’s Clarinet Virtuosi of the Past, articles about Weber from online sources, and G. Henle Verlag’s Urtext version of the concertino. Following this background information will be a performance of the concertino followed by a close examination of the forms, variations, and styles used in the piece
Avian Influenza in the United States and it\u27s Ramifications on our Market in the Poultry Industry
No full textWhile researching Avian Influenza (AI) in the United States, we have found that it has significantly impacted 47 states. Four main AI types have an impact on poultry farms. Avian Influenza can be reduced by taking preventative methods such as biosecurity and culling birds to have a healthy flock on the farm. Since 2022 egg-laying hens have been affected by the Avian Influenza Virus, causing egg inventories to become lower. Highly Pathogenic Avian Influenza (HPAI) has affected farmers tremendously; because of this, farmers must worry about their families\u27 source of income, their workers and the workers\u27 families\u27 source of income, and job loss. Once a flock has Avian Influenza, the farm must go out of commission for an extended time. Based on the results of this study, Avian Influenza has caused a loss in the poultry industry, affecting farmers, and leading to a severe loss of income due to low production outputs. The Avian influenza outbreak also affects consumers because they cannot or must reduce the amount of meat or egg products they purchase since prices are too high in grocery stores. Publicly available data from journal articles and disease monitoring websites were used to better represent the disease spread across the poultry industry. These methods have proved to cause a fast turnover in the poultry industry. Overall, Avian Influenza has impacted the United States by affecting the economic growth within the poultry industry. This horrific outbreak has caused a loss in profit for farmers and has caused substantial increases in egg prices for consumers
Premium Single Phase Motor for ABB Group
No full textABB Group is in search of a next generation premium single phase motor. An integrated drive paired to a three phase motor will allow the company to take advantage of current three phase motor automation capacity while presenting the end user with a simple, ready to use motor operating off of single phase power. This project is the design of such an integrated drive.
The drive will accept 115/230 Vac, single phase supply power and send it through a full bridge rectifying, voltage doubling circuit. This circuit will rectify the alternating current to direct current and increase the voltage to approximately 320 Vdc. The direct current will then be fed to an intelligent power module to be converted to 3 phases of alternating current. A microcontroller, powered via separate power supply circuitry, will govern the intelligent power module
Electron Charge to Mass Ratio
No full textThe purpose of this experiment is to confirm the e/m ratio and charge of an electron discovered initially by J.J. Thomson. We use an electron beam generated inside an e/m tube and Helmholtz coils that generate a magnetic field which deflects the path of the electrons. The radius of the path can be measured and from there the magnitude of the magnetic field and the charge-to-mass ratio can be found. This experiment was successful in confirming the results found by J.J. Thomson and his cathode ray experiments. The results of this experiment had a 0.5% error with the accepted e/m ratio value of 1.76 x 1011 C/kg.
