{"title":"Reducing Cement Plant Emissions via Algae Cultivation and Anaerobic Digestion","authors":"Hailey Muchnok, Ann C. Wilkie","doi":"10.32473/ufjur.25.133485","DOIUrl":"https://doi.org/10.32473/ufjur.25.133485","url":null,"abstract":"Concrete is an essential aspect of modern infrastructure, and is a much-preferred construction material as it is a highly resistant and requires low maintenance. Concrete is produced through the creation of a paste comprised of cement and water that is mixed with aggregates such as sand and gravel. However, the concrete industry is one of the largest consumers of natural resources globally, and the emissions associated with its production are very high. Cement, one of the primary constituents of concrete, emits 0.93 pounds of CO2 for every pound produced. Thus, concrete production is a major source of CO2 emissions and accounts for approximately 8% of global carbon emissions. As the global demand for concrete continues to increase, it is evident that efforts must be made to reduce emissions associated with its production to mitigate climate change. This research proposes that the cultivation of algae can be integrated into the process of cement production so as to reduce the emissions associated with concrete. Algae uptake CO2 through photosynthesis, having a CO2 bio-fixation efficiency of 10-50 times higher than terrestrial plants. Algae have the ability to capture 1.8 kg of CO2 per kilogram of algal biomass. Therefore, we hypothesize that, through the integration of algae cultivation and cement production, CO2 can be effectively recycled through a closed-loop system. Algal biomass can be cultivated using the CO2 emitted from cement flue gas. The cultivated algae can be harvested and used to produce methane gas (CH4) via anaerobic digestion, which can in turn be used to power the cement plant, which will in turn produce more CO2 to be captured through further algal cultivation.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There has been an increase in research that focuses on the moral grey areas seen in popular entertainment fiction. The grey areas of morality point to characters having a more ambiguous nature, commonly called anti-heroes. There is little research to date on the increased prevalence of the anti-hero archetype. The main goal of this content analysis was to discern how the morality of the hero-type character has evolved. A small longitudinal sample of American action movies (n=30) from the past 50 years was analyzed; discerned by total gross and popularity ratings. Morality-As-Cooperation Theory proposed by Curry et al. (2019) was used to determine the levels of the morality of the hero-type character in the coding schema. After each movie was coded, a percentage was computed for moral and immoral actions. The data was then interpreted to gauge whether the characters acted consistently good, showing a prototypical hero; or ambiguously, which would be consistent with an anti-hero archetype. Results of the study revealed that there was a strong positive correlation between the immoral actions of hero-type characters throughout the last fifty years. The findings should help to fill in the gap in the literature on the prevalence of anti-hero-type characters in movies.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their viewer’s engagement and comments have yet to be explored. A descriptive qualitative study was conducted to identify the difference in posts by RDNs and non-RDNs. For one month, the engagement on posts from 4 creators (n=2 RDNs and n=2 non-RDNs) was recorded. The number of positive and negative comments and common comment topics were identified. Four post categories were identified: preparing meals, consuming nutritious food/meals, nutrition/diet tips, and indirectly nutrition related. Likes were the most common form of engagement. Most comments were positive (70%). The creators with more followers received more negative comments (27%) than those with less followers (6%). RDNs received more comments asking for nutrition advice (n>44) than non-RDNs (n<13). RDNs posted more about preparing meals and nutrition/diet tips while non-RDNs posted more about consuming nutritious food/meals and indirectly nutrition related. Informing RDNs of the usefulness of TikTok and of the expectations of their audience is important as the use of social media in health care is increasing. Thus, further research is important to ensure that we can inform RDNs on the best social media practices.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model challenges the idea that to make is to translate something that exists only in the mind into something that exists tangibly outside of the human body. Rather, the experience of making is an integral relationship between mind and body, the body and object of work, and the hand and material. Through a series of ceramic and woodworking exercises, each with increasing scales and complexities, this research explores experiences of making to understand how the material is an active part of the thinking and making process and then speculates how this process relates to architectural education. Research methodology tracks each exercise’s steps from beginning to end, and then rigorously analyzes the roles that each material’s properties play in the process. Thinking through making raises architecture students’ awareness of all the forces that are part of a design project from concept through to final built work, and the final phase of this research looks at how specific exercises (derived from this project’s methodology) foster embodied thinking for a more holistic design process.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"14 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Efficacy of Bluetooth-Operated Heart Rate Monitors for Use in Construction","authors":"Pritham Pinni, Yahya Khan, Sylvia Murphy, Abhay Tak, Kayla Tran, Aaron Costin","doi":"10.32473/ufjur.25.133472","DOIUrl":"https://doi.org/10.32473/ufjur.25.133472","url":null,"abstract":"In the construction industry, workers are constantly exposed to different environmental and other hazards that pose risks to their health. Bluetooth-connected devices host the potential to reduce health risks to workers by tracking heart rate (HR), particularly upon implementation into an Internet of Things (IoT) framework. An Internet of Things (IoT) system is one in which multiple devices are connected to transmit information to each other in real-time. A literature and industry review has been conducted to determine which devices would be most applicable to monitor HR in an IoT system to accurately portray real-time worker conditions. Experimentally, the most applicable devices found were then put under field tests imitating traditional work conditions through the performance of specific activities. The performance and accuracy of the devices under these conditions were then evaluated from the data collected. The study has been designed to determine whether chest, finger, and wrist devices could be used to actively track HR. The devices used included the Viatom Wellue O2Ring finger monitor, Polar Ignite GPS Fitness Watch wrist monitor, and the Polar H10 chest monitor, serving as test cases to see if and by how much the location of the device on the body differed with the HR found. All three devices could connect to the IoT system and transmit data within a specific timeframe correctly. Covariance and standard deviations measured by the Viatom Wellue O2Ring finger monitor and the Polar Ignite GPS Fitness Watch trials among participants were above the normal thresholds, indicating non-negligible differences around the mean and showing disparities in the accuracy of these devices. Furthermore, the results were found to be too inaccurate for widespread commercial deployment for tracking mid to high HR levels while performing construction-related labor. Overall, the use of Bluetooth-connected devices to track workers’ HR and other vitals has the potential applicability to improve safety in hazardous environments. However, future technological development must occur before implementing predictive safety systems into real-time monitoring to effectively monitor laborers performing strenuous tasks in harsh environments.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136143002","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper aims to show that though it might be possible to come to this conclusion if the words they say are taken at face value, women in the French Resistance often represented their contributions in similar ways notably through the medium of memoirs that focus on duty, banalities of life, and a refusal to succumb to negative attitudes or victimization despite the horrors of the 1940’s. By comparing three notable female resistance figures (Lucie Aubrac, Germaine Tillion, and Agnés Humbert) in conjunction with numerous interviews of other women, it is evident that these women do not seek to efface themselves or other women’s contribution. Instead, the common bias of looking at Resistance efforts through a masculine heroism lens marginalizes these women’s contributions. By removing this lens or rethinking what female heroism means reconciles these women’s efforts to their true place in the historical record. The fact that these women deny their heroism does not downplay their contribution to the resistance effort, especially after constantly affirming the importance of these efforts.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"235 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136143098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prescriptive walking exercises guide how to walk to gain insight into the surrounding environment, which is particularly valuable for preliminary site analysis in architectural design. Sketching exercises complement the walking experience by prompting questions about composition, scale, and technique. Sketching requires interpretation of the environment to reveal new patterns and intricacies. Additionally, sketches serve as a tangible memory to reflect on during the design process. This study focuses on four primary walking exercises: Dérive, Synesthesia Walk, Radius Walk, and Traced Cup Walk. Author 1 followed by Design 6 students, tested and evaluated these exercises and found them helpful in grounding the rendering and narrative of studio projects in the urban context. This research is part of Author 2’s broader study, culminating in a guidebook outlining applicable walking and complementary visual exercises for the architectural design process.","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136142311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mutations result in decreased PGRN expression. PGRN is highly expressed in peripheral immune cells and microglia and regulates cell growth, survival, repair, and inflammation. As well, PGRN is implicated in regulating lysosome function, however, the exact role of PGRN in lysosomal function and how this contributes to inflammation and degeneration is not entirely understood. To better understand the role of PGRN in regulating lysosome function, this study examined how loss of GRN impacts lysosomal and cathepsin activity. Using mouse embryonic fibroblasts (MEFs), immunocytochemistry and immunoblotting assays were performed to analyze fluorescent signal from LAMP1 (lysosomal marker) and BMV109 (marker for pan-cathepsin activity). GRN-/- MEFs exhibit increased expression of pan-cathepsin activity relative to GRN+/+ MEFs, and significantly impacts expression of LAMP1. The significant increase in pan-cathepsin activity in the GRN-/- MEFs confirms that PGRN loss does alter cathepsin expression, which may be a result of compensatory mechanisms happening within the cell. Further investigations will include assessing LAMP1 and BMV109 expression in microglia from GRN-/- mice, in the hopes of understanding the role of PGRN in lysosomal function in immune cells of the central nervous system and the diseases in which it is implicated.&#x0D;","PeriodicalId":92815,"journal":{"name":"Journal of undergraduate research (Gainesville, Fla.)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136143107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
