A gasolina automotiva é o combustível mais consumido no mundo, contudo, no Brasil, sua qualidade tem sido constante objeto de questionamento, principalmente no estado do Piauí. Uma análise realizada em 713 postos do estado do Piauí, em dezembro de 2011, pela Agência Nacional do Petróleo, Gás Natural e Biocombustíveis (ANP), revelou que 15,7% das amostras analisadas estavam adulteradas, representando um risco para o consumidor. O estado perdeu apenas para o Mato Grosso, que apresentou percentual de 17,4% de adulteração. Já no ano de 2012 o Piauí foi considerado o segundo pior estado do país em qualidade da gasolina comercializada aos seus consumidores. Diante do exposto esse trabalho teve como objetivo investigar a qualidade da gasolina comum e aditivada comercializada nos postos de combustíveis da cidade de Picos-PI. Foram coletadas amostras comercializadas em cinco postos de combustíveis localizados nos bairros Ipueiras, Bomba, Centro, Junco e Morrinhos. As análises foram realizadas no Laboratório de Pesquisa do IFPI- Campus Picos, onde foram analisadas quanto às características de aspecto e cor e teor de etanol anidro combustível na gasolina. As amostras de gasolina comum e aditivada analisadas apresentaram aspecto límpido e livre de impurezas. Observaram-se as cores laranja ou amarelo para gasolina comum e verde para gasolina aditivada, estando esses resultados dentro das especificações estabelecidas pela ANP. O teste do teor de etanol anidro revelou que dois postos apresentaram um teor de 27% de álcool etílico anidro combustível para as gasolinas comum e aditivada, e os demais postos um teor de 25%. Os valores encontrados estão de acordo com a legislação vigente, uma vez que não ultrapassam o valor de 27% de álcool etílico anidro, logo as gasolinas analisadas não estão adulteradas.

Published: January 2022

La zeolita ha sido usada en la agricultura para sustituir parte del N de los fertilizantes nitrogenados FN en los cultivos y con ello alcanzar una mayor eficiencia de aprovechamiento del N. El objetivo de la presente investigación fue estudiar la respuesta del maíz (Zea mays L.) a una sustitución de 0, 12.5, 25.0, 37.5 y 50% del N de cuatro fuentes de FN, así como la respuesta a la micorriza, en dos sitios de la Región Centro de México. El diseño de tratamientos fue de parcelas subdivididas, donde la micorriza se ubicó en las parcelas grandes, las fuentes de fertilizantes en las parcelas medianas y las sustituciones del N en las parcelas pequeñas. El análisis de la información se realizó mediante regresión. En Colonia Francisco Villa se observó un mayor rendimiento de grano con una sustitución de 25% del N, entre 9.5 y 10.3% en todos fertilizantes sin micorriza y la micorriza dio un menor rendimiento de 197.4  kg ha-1;en el sitio Matlahuacales se observó un  mayor rendimiento con una sustitución de 25.0-37.5% del N, de 20.7% para  la urea, sulfato de amonio y fosfato diamónico, y de 36.6% para el nitrato de amonio, sin micorriza, y la micorriza con fosfato diamónico dio un mayor rendimiento de 602.5 kg  ha-1. La sustitución del 25.0% del N dio los máximos ingresos netos en Colonia Francisco Villa, mientras que en Matlahuacales, fue la sustitución de 37.5% la que tendió a dar mayores ingresos netos.

O estabelecimento de sistemas intensivos de cultivo e a simplificação dos ecossistemas ocasionam a diminuição gradativa dos artrópodes do solo. Devido as extensas áreas empregadas na monocultura da cana-de-açúcar, bem como as novas técnicas e tecnologias para realização da colheita mecanizada, tem favorecido o aumento de insetos nocivos que provocam prejuízos significativos a cultura. Vários fatores atingem os organismos de solo, como: tipo de solo, vegetação e as condições climáticas. A cobertura do solo e o tipo de solo são determinantes para composição e a riqueza dos artrópodes. Os artrópodes do solo são fundamentais para o funcionamento e equilíbrio do solo. A presença de determinados grupos específicos juntamente com sua densidade e quantidade em um sistema podem ser utilizados como indicadores da qualidade do solo. O ensaio foi conduzido em áreas de cana-de-açúcar e em uma área de preservação permanente (A.P.P.) localizadas no município de Bom Jesus de Goiás-GO, com altitude média de 598m definido pelas coordenadas geográficas Latitude: 18° 12' 11'' Sul e Longitude: 49° 44' 3'' Oeste. O ensaio então, foi composto por: T1 – Área de Preservação Permanente (APP), T2 – Área de cana-de-açúcar de 2º Corte (Plantio 2017) e T3 – Área de cana-de-açúcar 3º Corte (Plantio 2016). O delineamento experimental empregado foi o inteiramente casualizado com 10 repetições, cada repetição foi composta por uma armadilha de pit-fall, e 2 datas para as instalações das armadilhas (17/09/2019) 1ºdata e (17/10/2019) 2º data. Conforme os dados obtidos a área de preservação (A.P.P.) obteve maior riqueza de artrópodes de solo em relação às áreas de manejo convencional de cana-de-açúcar. Entretanto, com relação á densidade, as áreas de cana-de-açúcar obtiveram maiores densidades populacionais de artrópodes de solo Assim, podemos concluir que o manejo convencional de cana-de-açúcar reduz a diversidade dos artrópodes de solo e ocasiona o aumento da densidade populacional de insetos predadores.

Se investigaron los niveles de concentración de Cadmio (Cd) y Plomo (Pb) en el ostión Crassostrea virginica, que representa uno de los recursos más importantes en la pesquería tradicional del estado de Tabasco y en los sedimentos adyacentes a los bancos ostrícolas muestreados. 50 ostiones fueron colectados por buceo autónomo y los sedimentos fueron obtenidos con una draga manual de 10 lb, mensualmente durante un año y analizados para conocer las concentraciones de metales pesados por cuadruplicado. Se tomaron muestras de los tejidos blandos completos y de los sedimentos en tres puntos diferentes de la laguna Mecoacán, se procesaron bajo los criterios de la NOM-117, en una digestión ácida con HNO3 y fueron analizadas con el Espectrofotómetro de Absorción Atómica. Los resultados demuestran que tanto el ostión como los sedimentos presentan altos niveles de Cd y Pb. Los niveles de metales pesados detectados durante el año de estudio, se encontraron por arriba de los límites que establecen la NOM-129-SSA1-1995 y por la FDA (Administración de Alimentos y Medicamentos de los Estados Unidos). De la misma manera, se observó una elevación progresiva de los metales a medida que se reducía la distancia a la zona costera del municipio de Paraíso, Tabasco; lo cual sugiere que el ostión por sus hábitos alimenticios y el hábitat donde se desarrolla es más susceptible a la contaminación.

As fraturas de mandíbula são comuns na rotina do médico veterinário clinico de pequenos animais, o tratamento visa imobilizar a lesão para restabelecer a mobilidade funcional do osso bem como a alimentação e mastigação natural. A determinação da terapêutica está condicionada a alguns fatores: tipo de fratura, localização, presença de dentes, oclusão dentária, raça e idade. Não há uma técnica de escolha ideal para todas fraturas, pois cada caso tem que ser analisado, levando em consideração os diversos fatores para utilizar o tratamento mais efetivo para determinada situação. Os novos tipos de materiais e tecnologias digitais são tendências atuais que permitirão otimizar os protocolos de tratamento de fraturas de mandíbula. Não há uma técnica de escolha, portanto, objetivou-se relatar um caso clinico cirúrgico de um cão, macho de 3 anos de idade e com fratura unilateral do ramo horizontal do corpo mandibular direito. A metodologia de escolha para o tratamento foi a utilização de placa bloqueada e fixação por osteossíntese cirúrgica. Após 90 dias de tratamento clinico e cirúrgico, o animal foi liberado de seu tratamento em perfeito estado de saúde.

La presa la Estanzuela (Pachuca de Soto, Hidalgo) es un importante cuerpo de agua perteneciente a la cuenca del Río Actopan que recibe grandes cantidades de descargas industriales y agroquímicas. El agua de esta presa es tratada en una planta potabilizadora para poder proveer de agua de consumo a los habitantes de los municipios de Mineral del Chico y Pachuca. En este trabajo se usó el bioensayo de manchas en alas de Drosophila melanogaster para determinar la genotoxicidad de muestras de agua superficial y profunda. Se realizaron tres muestreos de agua: abril, junio y octubre 2017-2018, que se probaron al 50 y al 100%. En el ensayo en alas de Drosophila melanogaster se empleó la cruza estándar (ST) y la de alta bioactivación (HB). Se demostró que el ensayo en alas de Drosophila es un buen sistema para monitorear la toxicidad potencial de las muestras de agua debido a descargas antropogénicas.

O objetivo deste estudo foi avaliar os efeitos de diferentes doses do aditivo acidificante (sulfato de alumínio) - [0, 200, 400 e 600 g/m2] no tratamento da cama aviária e da densidade de alojamento (8 e 9 aves/m2) sobre o desempenho zootécnico e características de carcaça de frangos de corte. Foram utilizados 532 pintos machos de um dia de idade, com peso inicial médio de 46 g ± 2,3. As aves foramdistribuídas em delineamento inteiramente casualizado e arranjo de tratamento em fatorial 4x2, com sete repetições. Além do desempenho também foram avaliadoso rendimento de carcaça edos cortes (peito, coxa e sobrecoxa), bem como a prevalência de lesão nos pés das aves. A análise dos dados foi realizada utilizando o procedimento MIXED do programa estatístico SAS® (versão 9.2). O uso doaditivo e a densidade de alojamento não interagiram sobre desempenho de frangos de corte. Em geral, o aumento da densidade afetou negativamente o ganho de peso e a conversão alimentar. A dose do aditivo e a densidade de alojamento interagiram para o rendimento de carcaça. O aumento da dose do aditivo diminuiu o rendimento de carcaça, quando a densidade foi de 9 aves/m2. Em conclusão com base na densidade de alojamento e usando derivações da equação de superfície, foi possível recomendar a adição de 193,22 g do aditivo acidificante por m2. Portanto, a dose ótima de inclusão de sulfato de alumínio que favoreceu aumento do rendimento de carcaça é igual a (Y = 78,013 + 0,0114x - 0,00002952x2).

Se seleccionó una población de 276 bovinos hembra adultos lecheros raza Holstein-Friesian de 38 a 48 meses de edad. La brucelosis se diagnosticó en muestras de leche con la prueba PAL y iELISA, bajo los protocolos establecidos. Los resultados obtenidos con la técnica PAL se tuvieron 77 muestras negativas, 15 positivas y 4 control de la placa 1 con un total de 96 muestras; se obtuvieron 86 negativos, 6 positivos y 4 control de la placa 2 con un total de 96 muestras; y 83 negativos, 9 positivos y 4 control de la placa 3 con un total de 96 muestras. Se tuvo mayor porcentaje de detección 82.8% a Brucella abortus en las muestras analizadas por medio de iELISA que con las muestras analizadas con PAL 46.92%. Se concluye que el índice de frecuencias para determinar una comparativa entre ambas pruebas para determinar costo beneficio, entre PAL y iELISA, tiempo de análisis la PAL es más específica 48.93% que la prueba iELISA 19.83% y adicionalmente la prueba iELISA es más sensible 76.92% que PAL 14.85% para diagnosticar brucelosis bovina en tanque de leche. Se deduce que la prueba iELISA presento más frecuencias positivas, por lo que es una prueba más sensible que la PAL. Sin embargo, PAL es más rápida de realizar y es menos costosa que iELISA.
O ciclo estral da fêmea felina silvestre em cativeiro / The estrous cycle of the female felid in captivity

Published: January 2022

O monitoramento do ciclo estral da fêmea felina em cativeiro é essencial para tentar reverter o declínio significativo da população devido à perda de habitat e caça. Desta forma, os zoológicos e criadouros buscam manter a linhagem genética e a biodiversidade dentre os felídeos, por meio da reprodução em cativeiro. A maioria dos felinos tem dificuldade de reproduzir em cativeiro por diversos motivos, um exemplo é o estresse causado pela ambientação errônea do recinto. Para compreender a endocrinologia, é necessário realizar o monitoramento hormonal, podendo ser feito através da análise de amostras fecais e de urina, sendo o primeiro método mais efetivo, pois os felinos excretam mais esteroides gonadais pelas fezes. A maioria dos mamíferos detectam as mudanças estacionais por meio de fotoperíodo. Sendo assim, uma baixa quantidade de melatonina como resultado de maior período de luz, promove a produção do hormônio liberador de gonadotrofinas (GNRH), responsável por estimular a liberação de hormônio folículo-estimulante (FSH) e de hormônio luteinizante (LH). O ciclo estral da fêmea felina é composto de cinco etapas, sendo elas proestro, estro, interestro, diestro e anestro. Caso o fotoperíodo ocorra adequadamente, a fêmea pode apresentar consecutivamente o proestro, estro e interestro, sem ovulação, com ou sem acasalamento, podendo ocorrer variações entre cada espécie e indivíduo. O comportamento mais receptivo ao acasalamento caracteriza o estro, no qual as fêmeas passam a apresentar sinais de vocalização, agachamento, rolamento, lordose, deflexão da cauda, aumento da secreção vaginal, receptividade, afeição e começam a esfregar-se contra superfícies. Quando a ovulação é induzida pelo estímulo físico, como o coito, ela acontece na fase de estro e necessita de uma quantidade adequada de LH liberado e, geralmente, de várias cópulas para ocorrer.

Aún existen municipios y coberturas en los que no se han realizado colectas, por lo que se espera que el número de taxones aumente paralelo al proceso de sistematización.
Student Emotion in Mediated Learning: Comparing a Text, Video, and Video Game
Authors: Adams Aubrie , Toh Weimin
Published: January 2022

Although serious games are generally praised by scholars for their potential to enhance teaching and e-learning practices, more empirical evidence is needed to support these accolades. Existing research in this area tends to show that gamified teaching experiences do contribute to significant effects to improve student cognitive, motivational, and behavioural learning outcomes, but these effects are usually small. In addition, less research examines how different types of mediated learning tools compare to one another in influencing student outcomes associated with learning and motivation. As such, a question can be asked in this area: how do video games compare to other types of mediated tools, such as videos or texts, in influencing student emotion outcomes? This study used an experimental design (N = 153) to examine the influence of different types of mass media modalities (text, video, and video game) on college students’ emotions in a mediated learning context. Research examining the impact of video games on instruction has begun to grow, but few studies appropriately acknowledge the nuanced differences between media tools in comparison to one another. Using a media-attributes approach as a lens, this study first compared these mediated tools along the attributional dimensions of textuality, channel, interactivity, and control. This study next tested the impact of each media type on thirteen emotion outcomes. Results showed that six emotion outcomes did not indicate differences between groups (fear, guilt, sadness, shyness, serenity, and general negative emotions). However, six of the tested emotion outcomes did indicate differences between groups with students experiencing higher levels of emotional arousal in both the text and video game conditions (in comparison to the video condition) for the emotions of joviality, self-assurance, attentiveness, surprise, hostility, and general positive emotions. Lastly, students also felt less fatigue in the video game condition. Overall, implications for e-learning suggest that when a message’s content is held constant, both video games and texts may be better in inducing emotional intensity and reducing fatigue than videos alone, which could enhance motivation to learn when teaching is mediated by technology.

Communication strategies include the use of nonverbal or paralinguistic communication strategies such as the use of mime, gestures, facial expressions and eye contact as well as the use of pauses for emphatic expressions could be assimilated. Communication strategies also include the use of verbal communication strategies which need to be learned and developed. One of the verbal communication strategies is a Malaysian classified variety, topic fronting. The issue is that, despite being an achievement communication strategy, topic fronting does not abide by the English language grammatical rule. Thus, a high use of this strategy among ESL learners might affect them adversely especially in academic discourse. This study looked into this strategy among the TESL trainees in two universities from two states in Malaysia. The findings obtained from their focus group discussions (FGD) identified the utilisation of topic fronting in online interactions and methods of overcoming it as well as the inculcation of suitable communication strategies. This study’s findings show a low utilisation of topic fronting (1.142 per thousand words) with the highest theme on the “concession of topic fronting in teaching” at 2.20% average. In the effort to inculcate the TESL trainees’ awareness of their use of topic fronting communication strategy, they need to be involved in active FGDs and be provided with communication strategy trainings on alternative strategies, specifically linguistic strategies like exemplification, circumlocution and paraphrasing.

Published: January 2022

Critical reading is regarded by many as the most important of the four skills, and the desire to enhance the ability of ESL students to read critically is grounded in the knowledge that increased capability will give them an extra advantage in not only extracting valuable information from texts and acquiring knowledge but also in using it more effectively in their academic assignments. Therefore, it is necessary to carefully consider how to develop a module aimed at such outcomes, and this paper reports on a study that examines the opinions of a group of Malaysian undergraduate students at a Malaysian University with regard to their experience with the Critical Reading Module and to highlight the development of these ESL readers. Data for this paper was collected from a questionnaire distributed at two phases (week 1 and week 14) to sixty undergraduate students. The findings show that at the start of the research this group of Malaysian students demonstrated a lack of analytic skill. However, post-research they did show increased confidence as readers and they became more critical in their reading.
THE FEASIBILITY OF A PERSONAL LEARNING ENVIRONMENT (PLE) TO SUPPORT ACADEMIC WRITING: ESL PRE-SERVICE TEACHERS’ PERSPECTIVES
Authors: Said Noraini , Soekarno Megawati , Nik Mohamed Nik Zaitun , Pudin Chelster Sherralyn Jeoffrey
Published: January 2022

A recent trend has highlighted the need for a personal learning environment (PLE) in education as a system that helps learners take control of and manage their own learning. The current system which focuses on standardized learning support in the form of Learning Management System (LMS) is seen as restrictive and does not allow to accommodate the different needs of learners. Therefore, more language educators have started developing their own PLEs by focusing on two crucial elements: supporting learners’ needs and allowing more learner control. This paper presents an attempt to explore ESL pre-service teachers’ experience via PLE designed to support their writing needs. The researchers hoped that such a positive experience would influence the teachers’ pedagogical strategies and approaches in their teaching once they go into practice. In this qualitative case study, thirty-six third year ESL pre-service teachers at a tertiary education institution embarked on a fourteen-week course via the PLE. Qualitative data were gleaned from focus group discussion transcripts and written reflections. Thematic analysis was used to analyse the qualitative data. Overall, students have positive perceptions towards the PLE by detailing its benefits and usefulness. They also narrated some challenges and proposed suggestions to ensure prolonged engagement. The findings give support to the use of PLE, especially the instructor-made innovation for teaching and learning which allows more learner control and access.

Published: January 2022

This paper highlights the association of language use skills with self-confidence as a contributing factor to the determination of expatriate self-adaptability in a foreign cultural environment. The objective of this study was to examine whether the skills of using the local language of the host country are considered as a universal skill requirement for improvisation and self-skills among expatriate academics in Malaysian Public Universities. Utilisation of qualitative methods of semi-structured interviews on 35 lecturers with international staff status in four Malaysian Public Universities which were subsequently processed by inductive analysis for dominant and subdominant thematic classifications. The findings prove that the informants utilised language proficiency as a backup to recognise their ability to respond to external stimuli, thus producing positive value to themselves. The proactive process is done by trying to find answers to change and self-transformation while in a foreign country. Studies linking the elements of confidence and self-identity skills among expatriates are often highlighted, but the approach taken is to put the advantage to be utilised on the part of the organisation and not expatriates as the subject of the study. Therefore, the results of this study fulfil the search for answers regarding their identity as an expatriate, including exploring foreign cultures, releasing the culture of the country of origin, developing a network of contacts and assessing their potential and ability to deal with the challenges of life abroad. The direction of future research refers to the addition of value in the expatriate management literature by making basic concepts of interaction such as language proficiency as an element capable of increasing self-confidence and sketching the career development of self-initiated expatriates.

Published: January 2022

Essay writing is known to be a difficult skill among ESL learners, particularly rural students. The present study aims to measure the effects of a Place-Based Process Genre Module (PBPGM) on form four rural ESL learners’ persuasive and expository essay writing from the lens of Sociocultural Theory. A mixed-methods approach adopting a pre-test post-test control group quasi-experimental is employed to determine the significant difference and the Cohen’s d effect size. Purposive random sampling is used, and 30 students in control undergo the conventional teaching, and 30 students in the experimental group undergo a 16-hour intervention of the module. The results of the study indicate that there are significant differences and large effect sizes between the two groups. The experimental group outperforms the control group in both genres. The present study contributes to the field of teaching essay writing to rural ESL learners. The study recommends that process genre approach combined with place-based model texts be incorporated to strengthen and diversify scaffolding for teaching essay writing.

Education in Malaysia is an ongoing effort towards further developing the potential of individuals in a holistic and integrated manner to produce individuals who are intellectually, spiritually, emotionally, and physically balanced and harmonious, based on a firm belief in and devotion to God. This aspiration will not be successful if the emphasis is only given to academic excellence alone. Therefore, the co-curricular activities should also be embedded towards Higher Education Institutions (HEI) students in cultivating soft skill. Various co-curricular activities have been implemented at the university to offer valuable soft skills to students. But it is still a question how these soft skills are implemented, and how are the students' acceptance and understanding of the soft skills applied. Therefore, this study has been conducted to identify the effectiveness of students' soft skills after completing co-curricular activities. A questionnaire involving a total of 669 students was analysed. The result indicated the effectiveness of soft skills embedded within the co-curricular activities is high, with an average value of 5 (Likert Scale 1-7). However, some improvements are required to increase the effectiveness of soft skills to students. Co-curricular instructors/trainers need to have proper training on integrating soft skill in their courses. Providing good guidelines is vital to help the instructors/trainers develop suitable co-curricular activities for teaching delivery and evaluation. The instructors/trainers need to explain to students what soft skills they can obtain for each activity implemented. Additionally, to ensure students acquire the soft skill, they need to reflect on what they have learned and practices during co-curricular activities.
