Authors: Bomser Rachel , Gibson Heather J. , Zhang Hongping 
Published: November 2020

Since 2007, the University of Florida has hosted summer field-based, sustainability-focused study abroad programs in Australia, New Zealand, and Fiji. The purpose of this study was to examine the impact of these study abroad programs on change of major and subsequent career choice. Program alumni (2007-2019) completed an online questionnaire. N=94 responded to questions about impact on major (yes=1, no=2), career choice (yes=1, no=2), and open-ended responses. Data were analyzed using descriptive statistics, chi square, and content analysis. Five of 94 respondents changed majors and 39/93 reported study abroad influenced their career choice. Content analysis revealed participation influenced: n=14 to pursue a sustainability-focused career, n=8 to work in “a helping-profession”, n=6 to pursue ecotourism, and n=4 to study environmental law. Program participation seems to be influential for some in future career choice, but not major change.
Discrete Event Simulation of a Specialty Outpatient Clinic to Improve Patient Flow
Authors: Mangoni Samantha Lynn , Li Xuanjing 
Published: November 2020

The objective of this study was to test the validity and efficacy of discrete-event simulation (DES) in modeling a specialty outpatient clinic, and to apply the model to predict how the clinic could improve their patient flow. Arena software was used to develop this DES model. Real-life model inputs included the time that patients spent in each clinic process, clinic room utilization rate, and physician room schedules. The DES was validated via a comparison between the model’s outputs and raw clinic data, and further validated by clinic leadership. Once validated, the DES was modified to represent different scenarios, such as changes in clinic scheduling and resource usage. Analysis of the models revealed that adding two volunteers to escort patients in the morning and afternoon would decrease the queue time to see a physician by 33.9% and 65.2% respectively. The model results also suggested that there is not enough congestion in the clinic to warrant changingthe clinic scheduling from fixed room scheduling to un-assigned room scheduling. The results of the this study support the usability of DES in the modeling and analysis ofspecialty outpatient clinics to provide decision support.
Drying of Algae: Analysis of Oedogonium Dehydration Kinetics
Authors: Bjorndal Lars Cronje , Wilkie Ann C. 
Published: November 2020

Algae cultivation has multiple potential applications including biofuel production, wastewater treatment, and carbon capture. However, dewatering and dehydration remain a challenge for commercialization. Research has focused mainly on microalgae, but filamentous algae have recently gained attention due to their larger size and thus relative ease of harvesting. The drying mechanics of filamentous algae has yet to be fully understood and optimized. This study investigated the drying behavior of the filamentous algae Oedogonium at 50℃, 60℃ and 70℃. The moisture content of triplicate samples of microalgae and Oedogonium (intact filaments, fractured filaments, and aggregated forms) was measured during drying. Intact Oedogonium filaments were fractured using a food blender. Intact Oedogonium had an average shorter falling rate phase and higher diffusivity then microalgae at all temperatures, resulting in a 15%, 8.3%, and 11% faster total average drying time at 50℃, 60℃ and 70℃ respectively. Fractured Oedogonium further had a shorter falling rate phase than intact Oedogonium at 50℃ and 60℃ where its average total drying time was respectively 18% and 9% faster, but the effect of the fracturing treatment reduced with increasing temperature and became negligible at 70℃. Thus, Oedogonium appears to dry more effectively than microalgae, and fracturing Oedogonium results in faster dehydration at lower temperatures. These findings could help optimize industrial drying and assist in the commercialization of algae cultivation.
Word Learning in Two Modalities
Authors: McHugh Emily Anne 
Published: November 2020

A majority of research on language development has focused on examining spoken word learning and its role in the development of language, but there has been more limited research investigating the role of gesture and signed words in language development. This study investigated the impact of modality of word presentation on the learning of an associated meaning, the impact of modality of meaning presentation on the learning of an associated word, as well as the impact of crossing modalities on the speed and accuracy of learned associations. Participants viewed short videos of a person saying a non-word or making a sign paired with either a picture or a written definition. Outcome variables were accuracy and response times for recall of meanings.
The analysis of accuracy revealed a significant interaction between presentation modality and meaning modality. Accuracy in the nonword-picture condition was at ceiling and thus, significantly greater than accuracy in the nonword-definition condition and nonsign-picture condition. Analysis of response times found the main effect of meaning format to be statistically significant. Participants were significantly slower when meaning was presented as a definition compared to when it was presented as a picture. These results suggest that meaning associations with novel signs are learned equally fast and accurate as those associated with novel words. Additionally, they suggest that people recall imageable meanings faster than definitions. Finally, results also indicate that typically functioning adults maintain a robust ability for learning word-picture associations likely developed in childhood.

Published: November 2020

Introduction: The intention of Vietnam to participate in the European-Asian Moss Survey in the framework of The United Nations Economic Commission for Europe - International Cooperative Programme on effects of air pollution on natural vegetation and crops (UNECE ICP Vegetation) necessitates choosing appropriate moss species that grow in the tropical and subtropical climate of Vietnam. The three selected moss species, divided into phytogeographical elements, were as follows: Leucobryum (aduncum, albidum), Hypnum commutatum and Barbula indica.
Methods: The present study focuses on Central Vietnam where 18 samples of the three above moss species were collected in the vicinity of Dalat and Hue cities. Elements in the moss samples were detected by neutron activation analysis (NAA) at the IBR-2 reactor of the Division of Neutron Activation Analysis, Frank Laboratory of Neutron Physics, Joint Institute for Nuclear Research in Dubna, Russia.
Results: The analytical results for twenty-three trace elements, which were used to study elemental accumulation abilities of the three moss species in the air, were Na, Mg, Al, Cl, K, Ca, Ti, V, Mn, Fe, Co, Zn, As, Br, Rb, Sr, Sb, I, Cs, Ba, La, Th, and U. The accumulation abilities were found to decrease in the following order: Leucobryum > Hypnum > Barbula. However, Leucobryum, because of its short stem, was not judged to be a suitable candidate for biomonitoring.
Conclusion: The element accumulation abilities of Hypnum moss were better than those for Barbula, but both were comparable and could be used as indicators for air deposition monitoring; however, Hypnum was not widely present in Vietnam. Thus, Barbula indica moss could be used for performance of atmospheric deposition monitoring in Vietnam.

La adaptación del sector lácteo del Ecuador ante procesos de integración regional: el caso de la parroquia Tarqui (Azuay)
Authors: Mosquera Serrano Mariana Eulalia 
Published: November 2020

El artículo presenta los riesgos y las oportunidades a las que se ven expuestos los diferentes sistemas de ganadería lechera de Tarqui (Ecuador) en virtud de la apertura del mercado de lácteos que conlleva el Acuerdo Multi-partes suscrito por Ecuador con la Unión Europea y el Tratado de Libre Comercio que podría suscribirse con los Estados Unidos. Los riesgos están dados por las vulnerabilidades del sector lechero ecuatoriano en el plano productivo, organizativo y frente al apoyo gubernamental que el sector lechero europeo y estadounidense recibe a través de subsidios. Las oportunidades para los sistemas de ganadería más vulnerables, vendrían de la vinculación a mercados verdes y de comercio justo que están en crecimiento en los países desarrollados como los de la Unión Europea.

Auxemma glazioviana Taub. (Boraginaceae), conhecida como “pau branco”, está distribuída nos estados do Ceará e Rio Grande do Norte e é utilizada tradicionalmente no tratamento de cortes e feridas. As distintas atividades biológicas estão associadas a presença de quinonas, composto químico de ampla ocorrência na espécie. O objetivo desse estudo foi identificar as principais classes de metabólitos secundários, quantificar o contéudo total de polifenóis, obter a fração quinona (FQ) e avaliar o potencial antioxidante do extrato etanólico de A. glazioviana e da fração obtida. A partir do extrato foi realizada uma triagem fitoquímica e a quantificação de polifenóis totais. A obtenção e caracterização da fração quinona foi feita por meio de técnicas cromatográficas. O potencial antioxidante do extrato e da fração foi determinado pelos métodos, DPPH●; captura de radical livre ABTS●+, determinação do poder de redução do íon Fe3+ (FRAP) e capacidade antioxidante relativa (CAR). A prospecção química do extrato etanólico revelou a presença de flavonoides. A quantificação de polifenóis totais foi de 4,4822 mg AG/g.extrato. Nas análises antioxidantes, extrato e fração apresentaram resultados significativos, em que o EECCAG foi mais eficiente quando comparado a FQ. Os dados mostram que o EECCAG é potencialmente mais eficiente quanto a atividade antioxidante.

Published: November 2020

Nas últimas duas décadas, a América Latina tem passado por uma acelerada transição epidemiológica e nutricional, caracterizando uma elevação do sobrepeso e obesidade, e a redução da desnutrição, devido a mudanças como industrialização, urbanização, e o sedentarismo. Objetivo: mostrar a evolução nutricional da população adulta brasileira através da investigação de inquéritos, caracterizando as mudanças que ocorreram na última década. Metodologia: Estudo transversal, com base de dados secundários. A busca dos dados foi proveniente do Sistema de vigilância de fatores de risco e proteção para doenças crônicas por inquérito (VIGITEL). Primeiramente foi efetuada a análise dos dados, que possibilitou a constituição do corpus; com a análise possibilitando chegar-se a uma conclusão. Conclusão: A predominância de obesidade mórbida vem aumentou em todas as capitais do Brasil, com um percentual maior no publico feminino, nas faixas de idade de 25 a 44 anos, em todos os níveis de educação e regiões do país, um alerta para a necessidade de elaboração políticas públicas de promoção da saúde que incentivem a construção e a manutenção de estilos de vida saudáveis ainda na infância e na adolescência. Pois a obesidade é uma condição que pode facilitar o surgimento de doenças crônicas não transmissíveis, como doenças cardiovasculares, câncer, diabetes mellitus e hipertensão arterial.

Published: November 2020

Herbicidas com atividade residual têm sido utilizados como estratégia de controle de plantas daninhas no período crítico de competição das culturas. Contudo, é necessário monitorar o comportamento dessas substâncias no solo, visto que podem prejudicar cultivos subsequentes. O bioensaio é um método simples, barato, rápido e altamente sensível para detectar resíduos de herbicidas no solo, até mesmo em baixas concentrações. O objetivo deste trabalho foi selecionar espécies vegetais como bioindicadoras da atividade residual dos herbicidas saflufenacil e flumioxazina no solo. Foram avaliadas as espécies Panicum maximum cv. Tamani, Sorghum bicolor, Crambe abyssinica, Vigna angularis, Cucumis sativus e Beta vulgaris em combinação fatorial com seis doses do herbicida flumioxazina (0; 2,5; 5; 10; 25 e 50 g. ha-1) ou sete doses do herbicida saflufenacil (0; 2,5; 5; 10; 25; 50 e 100 g. ha-1), delineados em blocos ao acaso, com cinco repetições. Para o herbicida saflufenacil as espécies mais sensíveis foram a B. vulgaris, C. abyssinica e C. sativus. Para o herbicida flumioxazina as espécies mais sensíveis foram B. vulgaris e C. abyssinica. Considerando que as espécies adequadas para bioensaios são de fácil cultivo, rápido crescimento, sensíveis em baixas doses e de fácil visualização dos sintomas de fitointoxicação, a beterraba foi a que melhor apresentou estas características para ambos os herbicidas.

Published: November 2020

O processo estilóide é uma projeção óssea e pontiaguda que se origina do osso temporal e seu comprimento padrão varia entre 25 a 30 mm. Quando este comprimento é excedido, o acidente ósseo é considerado alongado, isso associado a sintomatologia específica pode indicar o diagnóstico de Síndrome de Eagle. Esse relato foi um achado anatômico, observacional, realizado a partir de osteotécnica em crânios secos de adultos, pertencentes ao laboratório de Anatomia Humana da Universidade Federal do Paraná - Campus Toledo. Os achados foram mensurados com paquímetro nove. Entre doze ossadas humanas analisadas, duas possuíam processo estilóide alongado, que tinham o comprimento de 45 mm do lado direito e 43 mm do lado esquerdo no crânio 1 e 41 mm do lado esquerdo e 39 mm do lado direito no crânio 2. Desse modo, as medidas dos comprimentos das apófises estilóides encontradas possuem um tamanho acima da média dos relatados na literatura, o que sugere que esse processo estilóide anômalo estaria comprimindo as estruturas adjacentes e causando sintomatologia clínica compatível com a Síndrome de Eagle. O conhecimento sobre a patologia, bem como suas manifestações clínicas pode favorecer a suspeita da doença pelos profissionais médicos.
