Authors:   , Vaz Valter
Published: May 2023

Nos últimos anos houve grande evolução nos equipamentos utilizados na aplicação de herbicidas, possibilitando a utilização de volume de calda bem abaixo do praticado a alguns anos e recomendados em bula para a maioria dos herbicidas. Entretanto faltam informações confiáveis sobre a eficácia de aplicações em baixo volume e o espectro de gotas a ser utilizado para herbicidas sistêmicos e de contato. Objetivou- se com esta pesquisa gerar informações acerca do volume de calda e o espectro de gotas a ser adotado para aplicações dos herbicidas fomesafen, atrazine e glyphosate, em diferentes taxas de aplicação e espectros de gotas. Para tal, foram conduzidos quatro experimentos em laboratório, casa de vegetação e campo, avaliando o espectro de gotas produzidos pela ponta TT11002 e o controle de picão-preto (Bidens pilosa) e corda-de-viola (Ipomoea triloba) pelos herbicidas fomesafen e atrazine, além do controle de braquiária (Urochloa brizantha) pelo glyphosate. O espectro de gotas gerado pela ponta de pulverização TT11002 nas pressões de 1,0 e 4,0 bar foi determinado em laboratório, utilizando analisador de gotas em tempo real por meio da técnica de difração de raio laser. Os herbicidas foram aplicados utilizando pulverizador pressurizado por CO 2 , com pontas TT11002 espaçadas de 0,50 m, operando nas pressões de 1,0 bar (muito grossas ≅ 460 µm) e 4,0 bar (gotas médias ≅ 292 µm) nos volumes de calda de 35, 70, 140 e 280 L ha -1 , obtidos por meio da variação na velocidade de aplicação. No momento da aplicação foram avaliados a porcentagem de área coberta e a densidade de gotas (gotas cm - ²) em etiquetas de papel hidrossensível, utilizando o programa DropScope ® . A aplicação dos herbicidas fomesafen e atrazine foi realizada em plantas de picão-preto com dois a três pares de folhas e corda-de-viola com duas a três folhas completamente expandidas. Para o fomesafen, melhores índices de controle do picão-preto foram obtidos quando a aplicação foi realizada com gotas muito grossas, na pressão de 1,0 bar, com volume de calda entre 65 e 280 L ha -1 , densidade de gotas superior a 60 gotas cm -2 e cobertura maior que 10%. O fomesafen não controlou a corda-de-viola. O atrazine promoveu excelente controle de corda-de-viola e picão-preto, assim como o glyphosate que proporcionou excelente controle de braquiária, em todos os volumes de calda avaliados (35 a 280 L ha -1 ), independente do espectro de gotas (médias ou muito-grossas). Palavras-chave: Baixo volume. Fomesafen. Atrazine. Glyphosate. Cobertura. Densidade de gotas.
Modelagem de florestas secundárias de Mata Atlântica utilizando a estatística bayesiana
Authors:   , Farias Aline Araújo
Published: May 2023

Os remanescentes secundários da Mata Atlântica (MA) são essenciais à manutenção e à conservação da biodiversidade no Brasil. Porém, há um desconhecimento dos fatores que impulsionam sua dinâmica e processos demográficos. A estatística bayesiana pode ser eficaz no estudo de sistemas complexos e heterogêneos nesses habitats fragmentados. Assim, o objetivo principal foi identificar os fatores que influenciam os atributos de árvores e espécies da MA por meio da abordagem bayesiana. A tese foi dividida em três capítulos abordando o crescimento (Capítulo 1), a biomassa (Capítulo 2) e a riqueza de espécies (Capítulo 3). Os modelos foram desenvolvidos por grupos ecológicos para avaliar a resposta de árvores em sete fragmentos da Mata Atlântica em Minas Gerais, Brasil. O efeito de variáveis ambientais e antrópicas, área e borda do fragmento (medidos pelo tamanho da floresta, perímetro e razão perímetro-área) foram estimados para os indivíduos e grupos ecológicos. O estudo revelou que as pioneiras crescem melhor em solos com maior teor de nutrientes e menor acidez, enquanto as espécies exigentes ou tolerantes à sombra preferem solos mais alcalinos com maior teor de cálcio e nutrientes. Os principais fatores afetando a biomassa foram variáveis relacionadas à fragmentação (ex.: área e razão de borda), que são mais prejudiciais às árvores de sucessão tardia. A riqueza de espécies pioneiras foi maior em fragmentos com maior perímetro, menor teor de alumínio e em estágios inicias de sucessão. Em contraste, o número de espécies de sucessão tardia, principais contribuintes aos estoques de biomassa e ao avanço da sucessão florestal, foi maior em fragmentos grandes e de menor perímetro. O histórico de uso menos intensivo do solo favoreceu tanto pioneiras quanto grupos de sucessão mais avançada. Nossos resultados permitem entender as respostas de árvores e grupos de espécies às interferências ambientais e antrópicas, ao mesmo tempo que confirma a eficácia dos modelos bayesianos para a análise de atributos da MA. Esse método pode ser utilizado para a elaboração de planos de recuperação florestal e gestão dos fatores atuando em habitats fragmentados.Palavras-chave: Florestas neotropicais. Biomassa florestal.

Authors: Sari Mega Mutiara , Suryawan I Wayan Koko , Septiariva Iva Yenis
Published: May 2023

The conducted study aimed to analyze the waste processing process from traditional ceremonies in Bali by examining the composition of the waste generated. Since most of the waste generated during these ceremonies is a biodegradable organic material, it is feasible to use sustainable bioconversion techniques such as Black Soldier Fly (BSF) larvae to convert this waste into useful products. In the study, a feeding trial was conducted using a garbage blender consisting of banana fruit, rice, banana leaf, coconut leaf, and flower wastes. The BSF larvae were fed at a rate of 40 mg/larvae per day with a total of 200 larvae. The researchers measured the key processing parameters including overall degradation (OD), waste reduction index (WRI), and feed conversion efficiency (ECD) which resulted in values of 41.27±0.42%, 3.30±0.03 g/day, and 7.82±0.43%, respectively. The study found that the dry residue produced during the process was around 30-31% and met the minimum standards set for compost or biomass fuel. Additionally, the total mass of BSF larvae produced was around 16-18% in one cycle, which is a high protein source that can be used to feed animals.

Comparing Arctic Surface Albedo Modification Geoengineering Solutions
Authors: Hotaling Madelyn , Harper Tammy
Published: May 2023

As global warming continues, the trend of rapidly declining arctic sea ice is expected to increase. The albedo effect, a regulatory process in earth’s climate, has become a positive feedback loop under climate change conditions. Sea ice has a high albedo, reflecting the sun’s energy. As sea ice continuously melts, more energy is absorbed, reducing albedo and leading to increasing temperatures that continue to propel the cycle. With increasing concerns regarding the effects of climate change, focus has turned towards geoengineering solutions, which employ human intervention to slow or stop the effects of global warming. Regarding the decline in arctic sea ice, specific solutions that lower global albedo are examined. One of the first solutions was Arctic Ice Management (AIM), which proposed the use of wind-driven pumps to restore the thickness of melting sea ice. A more recent proposal was Glass Microsphere (GM) geoengineering, which involved the addition of reflective glass spheres to ice, increasing the albedo of the surface. Few studies have compared geoengineering solutions; a crucial step towards implementation. Using a mixed methodology of statistical and content analyses, GM and AIM surface albedo modification solutions were compared in terms of sea ice volume and risk factors. Results suggest that GM geoengineering displays a significantly higher capacity to preserve or increase sea ice volume, but is also associated with a higher number of risks compared to AIM. Further comparison of the two solutions is suggested, along with the implementation of climate solutions that combine both mitigation and geoengineering strategies.
Investigating the Flow Rate of Granular Material in a Dynamic System
Authors: Shi Zinuo
Published: May 2023

The aim of this research is to investigate the effective method of predicting granular flow rate in a dynamic system, specifically a system undergoing vertical periodical fluctuation, simplified into uniform circular motion in this investigation. The preliminary investigation recognises the explanation from Beverloo’s relation in literature and confirmed its effectiveness in predicting the flow rate of granular material through a static silo. Hence, a mathematical hypothesis regarding the research question is established successfully, synthesizing the hypothesis of projection of effective diameter and vertical acceleration. In experiment, the hypothesis of the projection of effective diameter of the flow region is verified experimentally; whereas various implications arise when applying the conventional force analysis into the Beverloo’s relation. Although the current evidence is deficient in supporting me proposing the new law, this investigation systematically discuss the interconnection among the variables in Beverloo’s relation, and the current implication revealed shed a light on further research.
Finding the Most Effective Data Augmentation Techniques on Brain MRI Data Using Deep Networks
Authors: Raisinghani Nishank , McGill Mason
Published: May 2023

In 2020, over 250,000 people died from brain and Central Nervous System (CNS) tumors. Brain tumors account for around 85% or more of these. As of 2021, over 16 million people in the United States have been diagnosed with some type of cognitive impairment. The goal of this paper is to find the most effective set of data augmentations to correctly classify cognitive diseases with deep networks, using structural Magnetic Resonance Imaging (MRI) data. This paper demonstrates a Greedy optimization technique to find the most effective sequence of data augmentations out of blurring, distortion, position, and red noise (an overlay augmentation displaying random clouds of noise on the images). We sought to classify 3 tumors: glioma tumors, pituitary tumors, and meningioma tumors, as well as detect if there was no tumor at all. We also classified 3 stages of Alzheimer's disease: not demented, very mildly demented, and mildly demented, to further demonstrate the effectiveness of the data augmentation sequence.
Healthcare Inaccessibility in Rural Indiana: A Scoping Review
Authors: Moser Macy , Beiruti Sally
Published: May 2023

The majority of Indiana residents live in rural areas and suffer from significantly lower access to healthcare than their urban counterparts, leading to decreased longevity and in many cases a lower quality of life. The challenges faced among this cohort include generally poor health, high poverty rates, geographical impediments, healthcare worker shortages, and great distances to healthcare facilities. As poor health among rural residents drives higher demand for healthcare, the low number of practitioners in rural areas are unable to cope with patient needs. At the same time, access to reliable transportation prevents many from gaining access to healthcare facilities. Based on a literature review, including published academic, state, national, and governmental articles regarding disparities between urban and rural healthcare access in Indiana, this study explores the general health conditions of rural Indiana residents, disparities in healthcare worker and healthcare facility access among rural and urban Indiana populations, and an assessment of many proposed solutions. Although some solutions have resulted in incremental improvements, most have yet to yield meaningful results. The most promising recommendations for lasting improved access to healthcare for rural Indiana residents involve rapidly increasing the number of healthcare workers and facilities through the expansion of mid-level provider roles, including nurse practitioners and physician assistants, to augment physician care. Concurrently, increasing awareness of the availability of healthcare by these types of providers will result in improved access and better health for patients.
Prevalence of Negative Life Experiences Amongst Queer Youth Compared to Cisgender, Heterosexual Counterparts
Authors: Kurup Rohan , Paul Bishwajit
Published: May 2023

The CDC’s Youth Risk Behavior Surveillance System and Trevor Project’s National LGBTQ Youth Mental Health Surveys conclude that LGBTQ youth are at a higher risk for both mental illness and dating violence when compared to their cisgender, heterosexual (cishet) peers. However, both overlook negative life experiences such as loneliness, self-harm or emotional abuse amongst queer youth in relation to their cishet counterparts. The purpose of this study is to evaluate the prevalence of understudied negative life experiences amongst queer youth. To accomplish this, an anonymous web-based survey was distributed to various youth-centric online communities. This survey employed a Likert scale to gauge respondents’ attitudes and experiences. Cross-sectional analysis of the results confirms that queer youth are at a higher risk for negative life experiences, from depression and loneliness to physical bullying and dating violence. Novel findings include the fact that a large percentage of queer youth do not know how to respond to emotional abuse and are more likely than cishet adolescents to engage in unhealthy coping mechanisms. These results highlight the desperate need for accessible resources and educational opportunities regarding healthy relationships and coping mechanisms for all youth, especially for those who self-identify as queer.
A Review on the Natural Treatments of Allergic Rhinitis
Authors: Zhang Sissi , Cannata Angela
Published: May 2023

Allergic rhinitis affects millions of people and can significantly lower an individual’s quality of life. The most common treatment for allergic rhinitis lies in over-the-counter medications. However, most over-the-counter antihistamines are either sedating, interfere with an individual’s life, and make them more prone to accidents or are non-sedating, but less researched. An increasing distrust of pharmaceuticals alongside the development of tolerance and even eventual withdrawal to treatment has made it necessary to evaluate other avenues of allergy treatment, including herbal medications.

An analysis of 9 clinical trials on three herbs, butterbur, astragalus membranaceus, and tinospora cordifolia, determined that the butterbur’s efficacy is the most well-established. Meanwhile, astragalus membranaceus features the most potential for success in treating allergies, but confidence within its clinical trials is also the lowest. These herbs are generally more cost effective and incur fewer side effects than current antihistamines, but more research is necessary to ensure the safety of their consumption.

Published: May 2023

Can running injuries be predicted using only a dataset and machine learning models? This paper explores this question using classification models, including the Logistic Regression model and the Random Forest Classifier model. In the dataset used, ten features were taken into account when predicting running injuries. With slight modifications, the Weighted Logistic Regression and over and down-sampling Random Forest Classifier models were used to mitigate the imbalance in the dataset. The results suggested that the best model was Weighted Logistic Regression and that the best score metric to consider was the F-beta score.
Student Prioritization of World Language Learning
Authors: Begg Heather , Orlinski Jennifer
Published: May 2023

This paper compares a student’s priority of world language learning to an employer’s demand for multilingualism. Massachusetts high school students responded to a survey about world language availability and their success with and enjoyment of learning world languages, which was compared to statistics regarding the value employers place on multilingualism in job candidates. The results show that while students prioritize world language learning relatively highly, they pursue it more for fun than for practical value, likely due to the lack of visibility of world language needs in job postings. Employers need to clarify and emphasize these needs to encourage students to continue learning world languages and educators can assist in filling this gap by promoting the importance of world languages in their curriculums.
Repetitive Action and Cognitive Performance
Authors: Hong Wei
Published: May 2023

For many High School students, the repetitive action such as chewing gum is the ideal tool to help them achieve a consistent period of clear focus and wakefulness. However, as a chewing gum enthusiast, I have recently noticed a very unexpected pattern in my concentration performance when chewing gum compared to the task performed. Due to this particular reason, a study was designed in order to determine the type of task being performed and its relationship to the effectiveness of repetitive action (this study will only examine the repetitive action of chewing) on concentration when performing different tasks (Complex task & Simple task). The research study includes a review of literature, survey, and data analysis. The review of already existing literature regarding chewing gum and cognitive performance suggests that the action of chewing can serve as a distraction in specific environments (such as during an exam) and participants of the Tucha and Simpson study only showed more sustained attention 30 minutes into the study, with the prior time suffering from less sustained attention than usual. The survey data suggests a pattern between sustained attention in relation to the task performed. While chewing gum, the subject’s performance worsens while conducting a complex task (tasks requiring critical thinking skills), such as completing exams, solving puzzles, and memorizing specific details, but improves while conducting repetitive or hands-on tasks, such as exercising, copying, and coloring. The pattern may also exist between high accuracy tasks and low accuracy tasks, therefore accuracy may also be a distinguishing factor for chewing gum’s cognitive influence.
Music in Consumer Behavior: The Effect of Background Music on Time Perception for Online Consumers
Authors: Wang Sicheng , Mirny Daniel , Moulton Tyler
Published: May 2023

Background music plays an important role in shaping consumer preferences, decisions, and behaviors. While certain characteristics of music have received considerable attention in prior research (e.g., speed, volume, modernity, etc.), there has been limited attention devoted to the role of music genre in consumer behavior. The current research contributes to this stream of literature by empirically manipulating the genre of background music in an online consumer task and measuring consumer behavior. In a pre-registered experiment (N=1,161) online participants were played different genres of a musical composition. Their willingness to pay (WTP) for a variety of hedonic and utilitarian goods was measured, as was their perception of time spent on a task. Unlike past research, the present results shed light on how different music genres affect consumers’ time perception in a retail setting. Following a review of the prior literature on music and time perception in consumer behavior, empirical data are introduced and recommendations are presented for marketing managers and businesses.
Accuracy of Racial Trauma Model in Middle Eastern and North African American High School Students
Authors: Kojouri Hannah , Kukla Kevin
Published: May 2023

Introduction: Due to their classification as “White,” Middle Eastern and North African (MENA) individuals have been significantly underrepresented. Awad et al. (2019) provide a model of cumulative racial/ethnic trauma (CRET) within MENA Americans to fill in the knowledge gap around their unique racial experiences. Their model consists of factors on the micro and macro level, and outcomes on the individual and group level. This study adds to Awad et al.’s model by testing the accuracy of their CRET factors in order to improve our understanding of MENA Americans’ experiences. Methodology: A case study was conducted among 6 individuals of MENA descent from X High School. A deductive thematic analysis followed to determine the prevalence and significance of CRET factors through specific experiences within them. Results: Awad et al.’s model has many accuracies in terms of the prevalence of the CRET factors in the lives of MENA American high school students, especially the identity and recognition factor, but the theory lacks accuracy within its interpersonal discrimination factor. Conclusion: My research validated aspects of Awad’s model of CRET factors and identified areas that need improvement. These findings can be used for future social science research regarding MENA Americans’ experiences and aid in finding effective solutions to prevent or remedy their traumatic experiences.
A Look Into the Performance of mmWave 5G, 3G, 4G/LTE using PC Application, iPerf3 and DASH

With the fast-paced growth and expansion of cellular networks, the high bandwidth mmWave 5G is intensely sought after by businesses, medical centers and civilians. However, this relatively new network has already encountered various obstacles, such as instability, weakness and inconsistency. The nature of mmWave 5G consists of high frequency resulting in shorter wavelengths. This causes the current issues with upper layer management, which is seen with various applications such as video streaming. My research focuses on the performance and user quality of mmWave 5G, 3G, and 4G/LTE (4th Generation Long Term Evolution, which is standard wireless data transmission today) with PC application. While 5G and other cellular networks have been studied with mobile based applications, my research uses PC applications to see how PCs work with various networks. To analyze the performance of these cellular networks, I used iPerf3, a network tool, and DASH, a video streaming software. With iPerf3, I was able to understand the network via a client and server side that the test provided. With DASH, I was able to further my knowledge around the networks with new data around user experience (UE). I also analyzed how mmWaves react to different variables, such as signal blockage, and how that affects the user experience and overall performance. My findings reveal critical insights to how mmWaves perform with PCs by measuring various metrics to get Quality of Experience (QoE) and on user experience of mmWaves.

Published: May 2023

Social status is has been shown to influence school functioning. The purpose of this study is to investigate the influence of popularity on academic achievement and academic attitude in Chinese high schools. This paper examined the relation between popularity and academic achievement and academic attitude in a Chinese high school with 16 girls and 14 boys by using correlation analysis and linear regression analysis. The inconsistent result indicates that both sociometric popularity and perceived popularity are positively associated with high academic achievement. Only sociometric popularity is highly associated with better academic attitude. The findings reflect different academic cultures and values in varied cultures and highlight the importance of popularity in academic success.

The paper also presents a discussion of the advantages and limitations of these techniques, highlighting the challenges associated with implementing them in MG systems. Finally, investigation of the existing literature on the performance of intelligent control techniques in MG systems is presented, providing insights into their effectiveness in improving the energy efficiency, stability, and reliability of MG systems.
Design of Smart Prototype Pet Feeder Using Passive InfaRed (PIR) Sensors
Authors: Marlina Erni
Published: May 2023

Food is necessary to support daily life and in pets like cats. Pet feeders are usually carried out routinely by pet owners by taking the time to stay at home and feed the pets. With activities requiring animal owners to be outside the home for long periods, it is necessary to design a prototype that can automatically assist the process of providing food, especially dry food, to pets. So pet feeders can be carried out even though the owner is not at home and does not have spare time. The system was built using the C language related to the Code Vision tools that support the hex file compiler into the microcontroller. The research method used is the experimental method, namely conducting trials (trial and error) directly on the research object and the comparative testing method for testing the built system. The auto pet feeder prototype uses the ATMega8535 IC by utilizing a PIR (Passive InfraRed) sensor to detect movement around the animal bowl. The PIR sensor detects well as expected, and it has an effective detection range of up to 5 meters. Not only detects humans, but the PIR sensor can also detect other living things. The PIR sensor will send a signal to the microcontroller to open the valve from the food measuring station, which is driven by a DC motor based on the detected motion to drop food into the animal's bowl. PhotoDioda controls the amount of food falling into the animal's bowl. The test results of this tool show that at a distance of 0–6 meters, the PIR sensor can provide feedback or detect animal movements well.
