This dissertation mainly focuses on the investigations of the phenomena related to PT-symmetric optical lattice in a coherent atomic medium. First, a controllable photonic crystal with periodic Raman gain was constructed in …

Screening For Our Fathers: Representations Of Native American Masculinity In American Film, Jeromy Duane Miller

Graduate Theses and Dissertations

In this work, I examine representation of Native American masculinity in the American film industry. The American film industry began just over a century ago, and one of its earliest subjects was the Native American. Throughout its history, the American film industry has maintained a steady trajectory of exploitation and erasure of Native American men and their subsequent masculine qualities. While there are notable historical outliers and critical exceptions in the 21st century, Native American men in film have been continually reduced to corpses, devoid of significant social presence, and denied meaningful explorations of their sexuality and interpersonal identity. The …

Characterization Of Dirt On White-Shelled Table Eggs Through Image Analysis [Research Note], Maria Patricia Azanza, Dominic Panaligan, Bryan Kenneth Desierdo

The Philippine Agricultural Scientist

The study reports the laboratory-scale use of image analysis to categorize dirty white-shelled table eggs. Data generated from image analysis were subjected to statistical analysis and compared with established standards categorizing dirty white-shelled table eggs for washing and sanitation or for use in food processing. The average Quartile 1 (2.49%) and Quartile 3 (9.28%) values of percent surface dirt were found to be proximate to quality standard guidelines values of ≤ 3.12% and < 10% from USDA (2000) and PNS (2005), respectively. These limits were recommended as possible guidelines for classifying eggs into those that are acceptable as table eggs, acceptable for processing with washing and sanitation, and unacceptable for food use.

Resistance against insect pests is one of the most promising and highly favored characteristics of an economically important crop. In the Philippines, the Asian corn borer (ACB), Ostrinia furnacalis (Guenée), is the most destructive insect pest of maize. The discovery of Bacillus thuringiensis and the Bt toxin, which led to the development of Bt corn, effectively controlled this pest. In this study, four traditional varieties of maize that showed resistance against ACB were tested for the presence of Bt Cry1Ab protein. Out of these four, a traditional variety from San Carlos City, Pangasinan, which was initially thought to have natural …

Epinasty Accompanies Potassium Nitrate-Induced Flower Bud Break In 'Carabao' Mango [Research Note], Ulysses Besas, Calixto Protacio

The Philippine Agricultural Scientist

The hypothesis that potassium nitrate application promotes epinasty in ‘Carabao’ mango through increased ethylene production was investigated. The degree of drooping, apical primordium growth as affected by shoot ethylene and levels after potassium nitrate spraying were monitored. Evidence presented established for the first time in ‘Carabao’ mango that epinasty occurred just before flower emergence, coinciding with visible bud break, and extended up to 18 days, marking floral anthesis. The possible reasons could be the higher levels of ethylene at 0.31% and earlier increase of ethylene in the shoot apex at four hours and apical primordium growth. Increased ethylene levels at …

Interval Estimates: How To Make Them More Adequate And How To Use Them In Economic Analysis And Decision Making, Laura Adriana Berrout-Ramos

Open Access Theses & Dissertations

In many real-life situations, we need to make decisions in situations when we do not have full information about the consequences of different decisions. In particular, instead of the exact values of the relevant quantities, we only know lower and upper bounds on these values – i.e., we know an interval that contains the actual (unknown) value. These interval estimates often come from experts. This fact naturally leads to the following important questions: How should we make decisions under such interval uncertainty? How to gauge the quality of the resulting decisions? And if this quality is not sufficient – because …

Level Of Service For Parking Facilities Based On Search Time, Fernie Briones

Open Access Theses & Dissertations

Level of Service (LOS) is a term used by transportation engineers to identify the quality of service of transportation facilities to the public. The Highway Capacity Manual has yet to provide guidance on LOS analysis for parking facilities. Parking search time has been proposed by several researchers as the indicator for the LOS criteria for parking facilities. This thesis investigated the use of search time for LOS analysis for on street and off-street parking facilities. The analysis of LOS for off-street parking focused on the measurement of parking search time. Three search time measurement methods have been proposed: the license …

Combination Of Nir Triggered Lanthanide Upconverting Nanoplatforms With Fullerene For Controlled Drug Release And Photo Cancer Therapy, Lei Ma

Open Access Theses & Dissertations

Photodynamic therapy (PDT) is an emerging, externally activatable, treatment modality for various diseases, especially for cancer therapy. Similar to radiotherapy, the mode of action with PDT involves the use of electromagnetic radiation to generate radical species in situ. However, PDT is a much milder approach for cancer treatment. Because of the unique physicochemical properties of fullerenes (such as C60), many potential biomedical applications, including PDT, became possible with them. As a main principle of PDT, the anticancer properties of various fullerene preparations usually result from their ability to generate cytotoxic reactive oxygen species (ROS), after photoexcitation. However, because of the …

Open Access Theses & Dissertations

University campuses are the origins and destinations of a variety of trips generated by faculty, staff, students, and visitors. The vast number of trips that are attracted to university campuses result in parking congestion issues. In order to manage campus parking demand, universities establish Transportation and Parking Offices (TPO). This research has developed a two-stage procedure that can be used by TPOs as a tool for determining faculty and staff parking permit prices on university campuses. The first stage of the procedure is the determination of a single campus-wide base price (which may be regarded as the reference price or …

Arms Control 2.0: Updating The Cyberweapon Arms Control Framework, Evan Mulbry

Michigan Technology Law Review

This Note analyzes multiple problems with the existing arms control framework for cyberweapons as well as surveillance technology and calls for four specific areas of reform. First, the existing framework does not specifically enumerate the software controlled under existing arms control treaties, which can lead to gaps in international export control compliance. Cyberweapons should be enumerated with greater specificity to prevent confusing and disjointed implementation by states. Second, the divide between Wassenaar and Shanghai Cooperation Organization conceptions of what constitutes a cyberweapon reduces the effectiveness of international control because nations do not share an agreed upon cyberweapon definition. States should …

Content Moderation Remedies, Eric Goldman

Michigan Technology Law Review

This Article addresses a critical but underexplored aspect of content moderation: if a user’s online content or actions violate an Internet service’s rules, what should happen next? The longstanding expectation is that Internet services should remove violative content or accounts from their services as quickly as possible, and many laws mandate that result. However, Internet services have a wide range of other options—what I call “remedies”—they can use to redress content or accounts that violate the applicable rules. This Article describes dozens of remedies that Internet services have actually imposed. It then provides a normative framework to help Internet services …

Individuals As Gatekeepers Against Data Misuse, Ying Hu

Michigan Technology Law Review

This article makes a case for treating individual data subjects as gatekeepers against misuse of personal data. Imposing gatekeeper responsibility on individuals is most useful where (a) the primary wrongdoers engage in data misuse intentionally or recklessly; (b) misuse of personal data is likely to lead to serious harm; and (c) one or more individuals are able to detect and prevent data misuse at a reasonable cost.

As gatekeepers, individuals should have a legal duty to take reasonable measures to prevent data misuse where they are aware of facts indicating that the person seeking personal data from them is highly …

Postharvest 24-Epibrassinolide And Chitosan Treatments Affect Quality Of ‘Balady Banzahir’ Limes During Shelf Life [Research Note], Mohamed A. Awad, Adel Al-Qurashi

The Philippine Agricultural Scientist

Limes undergo internal metabolic changes during storage at ambient, resulting in rind disorders and green color fading that decrease consumer preferences and market demand. To elucidate the effects of exogenous 24-epibrassinolide (EBR) and chitosan (CT) treatments on the postharvest quality of citrus fruit, freshly harvested mature-green ‘Balady Banzahir’ limes were dipped for 15 min in 20 μM EBR and 1% CT alone or in combination and kept at ambient (23 ± 1°C and 60 – 70% RH) for 20 days. EBR or CT treatments retained fruit quality during shelf life as shown by higher green peel color (lower a* values), …

The Philippine Agricultural Scientist

Anubias barteri is an ornamental aquatic plant of economic importance worldwide. Effective removal of contaminants has been a major problem for the in vitro propagation of A. barteri. Hydrogen peroxide (H₂O₂) was applied as a pre-disinfectant to treat rhizome bud explants of A. barteri var. nana ‘Mini’ followed by disinfection with mercuric chloride (HgCl₂) to eliminate in vitro contamination. However, application of 0.1% HgCl₂ for 5 min without pre-disinfecting with H₂O₂ significantly reduced the contamination rate to 44.4% compared to other combinations. Moreover, in vitro shoots of A. barteri …

The Future Is Full Of Monsters: Queer Survival One Click At A Twine, 'Aolani N. Robinson

All HCAS Student Capstones, Theses, and Dissertations

Spurred by a desire to explore queer rhetoric through interactive forms of media, this project analyzed the game-making program Twine to uncover how independent queer creators use the tool to explore queer survival against time, capitalism, and constrained identities. A more accessible platform than other game-making tools, Twine’s unique interactivity puts the ability to make interactive games and stories into the hands of indie marginalized creators who are often overlooked in both mainstream gaming and queer rhetorics (Anthropy, 2012). Thus, this thesis contributes to queer rhetoric, game studies, and trans rhetorics by exploring the strategies indie Twine creators use in …

Activation Of Crtc2/Creb1 In Skeletal Muscle Enhances Weight Loss During Intermittent Fasting, Nelson E Bruno, Jerome C Nwachukwu, David C Hughes, Sathish Srinivasan, Richard Hawkins, David Sturgill, Gordon L Hager, Stephen Hurst, Shey-Shing Sheu, Sue C Bodine, Michael D Conkright, Kendall W Nettles

Department of Medicine Faculty Papers

The Creb-Regulated Transcriptional Coactivator (Crtc) family of transcriptional coregulators drive Creb1-mediated transcription effects on metabolism in many tissues, but the in vivo effects of Crtc2/Creb1 transcription on skeletal muscle metabolism are not known. Skeletal muscle-specific overexpression of Crtc2 (Crtc2 mice) induced greater mitochondrial activity, metabolic flux capacity for both carbohydrates and fats, improved glucose tolerance and insulin sensitivity, and increased oxidative capacity, supported by upregulation of key metabolic genes. Crtc2 overexpression led to greater weight loss during alternate day fasting (ADF), selective loss of fat rather than lean mass, maintenance of higher energy expenditure during the fast and reduced binge-eating …

Providing Hypertension Education To African Immigrants At A Southern California Congregation During The Covid-19 Pandemic, Esther Oshunluyi

Doctor of Nursing Practice (DNP) Projects

Objective: To review methods that could contribute to improved knowledge of hypertension among African immigrants at a California congregation. The difference in the management and outcomes of hypertension between African Americans and Whites is most disparate in cardiovascular disease, with lack of education documented as a major contributor for African Americans (Lackland, 2014) and African immigrants (Turson-Ocran et al., 2020). African Americans differ slightly in culture, health, and migration history from Africans who are 21st century immigrants from Africa (African immigrants); however, there are more similarities than differences between them (Terrazas, 2009).
