Authors: Feitosa Murilo Carvalho , Aquino Adelmo Artur De , Lavor Otávio Paulino
Published: June 2020

A matemática é aplicada em diversas áreas do conhecimento e o seu entendimento fornece base para aprender outros conteúdos na vida cotidiana e na trajetória acadêmica de qualquer pessoa. No entanto, devido à dificuldade de interpretação e visualização, alguns conceitos, como retas e planos, apresentam índices de aprendizagem não satisfatórios em muitas ocasiões, mas que podem ser contornados com o auxílio de tecnologias nas metodologias de ensino, e com isso vem a ideia da utilização de objetos de aprendizagem. Logo, esta pesquisa tem por objetivo uma investigação prática do ensino de retas e planos auxiliado pelo GeoGebra 3D Mobile. Para tanto, discentes matriculados em turmas de geometria analítica são divididos em dois grupos, sendo um destes de caráter experimental e o outro de controle. O grupo de controle tem aulas sem o intermédio do recurso tecnológico enquanto que o grupo experimental tem a intervenção do aplicativo em suas aulas. Ao grupo experimental, após apresentação do aplicativo, são ministrados os conteúdos utilizando as funcionalidades da ferramenta em questão. Ao final, todos os alunos são submetidos a uma avaliação de aprendizagem que aponta que os discentes do grupo experimental tiveram resultados mais satisfatórios que o grupo de controle. Isso mostrou que a aprendizagem pode ser dinâmica e interativa quando recursos tecnológicos, como o GeoGebra, são utilizados em sala de aula. A pesquisa revelou apontamentos pedagógicos muito pertinentes quanto a forma com que foram divididos os grupos em questão, trazendo assim contribuições metodológicas consideráveis em pesquisas dessa natureza.

Published: June 2020

El peso corporal se relaciona directamente con el estado de salud. Por lo tanto los extremos de bajo peso y obesidad representan problemas que afectan a mujeres y hombres en todas las etapas de la vida. Por lo anterior, el objetivo de estudio fue comparar indicadores del estado nutricio (IMC y peso) entre estudiantes adolescentes mujeres y hombres del sur de Tamaulipas.
Se realizó un estudio transversal, descriptivo y comparativo. La muestra se formó por estudiantes de escuelas secundarias de los municipios de Ciudad Madero y Tampico, Tamaulipas. La muestra fue no probabilística con un muestreo por conveniencia con n=344. Se obtuvieron peso y estatura para calcular el IMC.
Entre los resultados se encontró que la media de IMC para el total de la muestra (ambos sexos) se ubicó en normopeso. Mediante la prueba de comparación se identificaron diferencias significativas en el peso, más no en el IMC.  Además se observa una tendencia porcentual mayor hacia bajo peso en las categorías de IMC para ambos sexos. Por tanto se concluye que entre los estudiantes adolescentes del sur de Tamaulipas predomina un estado nutricio saludable (peso normal), que el IMC es igual para ambos sexos, sin embargo los adolescentes hombres pesan más que las mujeres.
Efectos biológicos y uso herbolario del género Croton. Revisión sistemática
Authors: Romero-Juárez Guadalupe C. , Ortiz Mario I , Cariño-Cortés Raquel
Published: June 2020

AntecedentesDesde la antigüedad, los seres humanos han tenido la necesidad de buscar alternativas naturales para combatir diversas enfermedades. Los principios activos de géneros de Croton (familia Euphobiaceae) se usan como alternativas terapéuticas naturales en la medicina tradicional en África, sur de Asia y Sudamérica. Específicamente, Croton hypoleucus (Ch) se usa en la medicina tradicional mexicana para el tratamiento del dolor de estómago, gastritis, tos e infecciones locales. Por tanto, el objetivo principal de la presente revisión es mostrar las actividades biológicas y los usos clínicos de Croton.

Método

Se realizó una búsqueda bibliográfica en PubMed, Scopus, Web of Science. Revisamos los estudios experimentales de modelos in vitro e in vivo de los componentes de las diferentes especies de Croton publicados de 1980 a 2019, donde de cada artículo se sintetizó la información sobre la eficacia y los efectos biológicos de cada compuesto aislado.

Resultados

Se incluyeron un total de 16 estudios experimentales. No se encontraron estudios clínicos en la literatura. Algunas especies de croton produjeron actividad citotóxica de baja a moderada contra diferentes líneas celulares. Estos efectos se atribuyen principalmente a diterpenoides, crotónidos y principalmente a clerodanos. Un extracto puro de Croton hypoleucus demostró moderada actividad hepatoprotectora y antioxidante.

Conclusión

La literatura indica el posible mecanismo de acción de algunas actividades biológicas de los compuestos de Croton. Sin embargo, la información disponible es escasa. Por lo tanto, se necesita realizar más estudios en diferentes modelos experimentales para clarificar la seguridad y eficacia de sus componentes activos con el fin de tener alternativas naturales con el mismo efecto o mejor que los medicamentos convencionales.

Enzyme Activity Variability and Comparison in Soils under Medicinal versus Crop Plants of Anguo City, China
Authors: Liu Wenke
Published: June 2020

Long-term continuous cultivation of different plant species in a similar agroecosystem intensively may result in divergent variability in soil fertility, particularly soil biochemical properties. In this study, an investigation was conducted to clarify the variability of five soil enzyme activities (urease, protease, catalase, polyphenol oxidase and alkaline phosphatase) of croplands under medicinal plants (herbal fields) and food crops (crop fields) in Anguo city, a traditional cultivation base for Chinese medicinal plants in China. The results showed that five soil enzyme activities were similar between herbal and crop fields. However, soil urease and alkaline phosphatase activities of herbal and crop fields decreased significantly with soil depth (0-60 cm), while protease, catalase, polyphenol oxidase activities were similar in all soil layers for two kinds of fields. There were largely variation scenes at linear correlation analysis between soil physicochemical traits and enzymatic activities under medicinal plant versus crop fileds although extensively significant correlations were presented. In conclusion, soil enzyme activities were similar in two type of farmlands, and soil urease and alkaline phosphatase activities decreased with soil depth for both fields. Inconsistent linear correlations between soil physicochemical traits and enzymatic activities under medicinal plant versus crop fields were presented, so soil enzymatic activity variation was subjected to soil physicochemical traits dominated by agronomic managements designed for specific plant species.

Published: June 2020

The present study was run in the laboratory of the Department of Horticulture, Bangladesh Agricultural University, Mymensingh during the period of 15 May to September, 2016. The objectives of the study were to determine the effects of different postharvest treatments on the storage behaviour of litchi. Eight postharvest treatments viz., control, fruits stored in 50µ polypropylene bag at ambient temperature, fruits stored in 75µ polypropylene bag at ambient temperature, fruits stored in 100µ polypropylene bag at ambient temperature, fruits stored at 4ºC temperature, fruits stored in 50µ polypropylene bag at 4ºC temperature, fruits stored in 75µ polypropylene bag at 4ºC temperature, fruits stored in 100µ polypropylene bag at 4ºC temperature were assigned to the litchi fruits. The single factor experiment was laid out in a completely randomized design with three replications. 75µ polypropylene bag at low temperature (4ºC) caused minimal weight loss, whereas, the untreated fruits exhibited maximal weight loss. The pericarp turned brown within 4 days of storage in the untreated fruits, while polypropylene bags helped keep its bright red colour, but microbial decay was evident at the end of the storage period. Different postharvest treatments showed highly significant variation in the shelf life of litchi. Among the treated and untreated fruits, 75µ polypropylene bag at low temperature (4ºC) treatment exhibited better storage performance. The fruits kept in 75µ polypropylene bag at 4°C showed the highest shelf life (20.67 days) followed by 50µ polypropylene bag at 4°C (20.33 days), and it was the lowest in the untreated fruits (3 days).

Published: June 2020

Clarias gariepinus Burchell, 1822 is a catfish with high commercial value in the Democratic Republic of Congo and in several African countries. The breeding of this species is controlled, but Congolese fish farmers are confronted with the problem of a lack of compound feed in the form of granules. The recovery of local agricultural waste would be essential to fill this gap. The objective of this study is to evaluate the effect of three types of food based on local agricultural by-products on the growth of C. gariepinus. The 25%, 41% and 51% crude protein feed formulas were tested in duplicate for 96 days. Fry averaging 2.20±0.43 g were distributed in 6 closed-loop plastic containers. The fish were fed twice a day by hand. Weighing and measuring took place every 14 days. The results obtained show that the highest final average weight (g) and specific growth rate (%/d) (F = 2.87; p = 0.002) are obtained with food A1: 27.5±1.9 g and 0.25±0.15% /d respectively. It took 812.6 Congolese francs to develop food A1, 942.6 congolese francs to produce the A2 ration and 836.6 congolese francs to produce food A3. The A1 ration is the one that gave a better compromise in price and quality by promoting fish growth at a lower cost (3.827 congolese francs).

It should be noted that the yield of EOs obtained at the flowering stage (2.2%) is almost double that obtained at the foliage stage (1.2%).Gas Chromatography coupled to a mass spectrophometerGC-MS analysis revealed the presence of p-Menth-4 (8) -en-3-one, as the most frequently constituents of Mint, better known as Pulegone.

We performed two ways of treatments: by contact and by alimentation (the duration of treatment is 3and 6 days respectively).

By contact we have acquired a total mortality (100%) using the highest dose (48μl/ml) with a LD50 of 12.58 μl/ ml. In the opposite, by ingestion, the mortality rate obtained for the same dose was 80%while the LD50 was23.98 μl/ ml.

Using the letal doses, the comparative effect of contact and ingestion between the essential oils show that the action by contact is stronger and faster to enter in the insect via the cuticulethan that byingestion. Finally authors concluded that the results were very satisfactory.

A study was conducted for two consecutive years to determine the yield and system productivity of two cropping patterns viz. IP: (Wheat - Jute - T. aman) improved pattern with improved management practices and FP: (Fallow - Fallow - T. aman) farmers’ pattern with farmers’ management practices in char (adjacent to the river) area of Netrakona region of Bangladesh. The experimentswere laid out in a randomized complete block design with 10 dispersed replications at a farmer’s field. The two years mean data showed that the total component crops of IP (wheat-jute-T. aman rice) gave higher yield as well as a by-product in both years. The higherrice equivalent yield (10.52 and 10.63 tha-1), production efficiency (30.13 and 30.43 kg ha-1 day-1) land-use efficiency (87.13 and 87.84%)and benefit cost ratio (2.15 and 2.11) pointed out the dominance of the improvedpattern over the farmer’s existing pattern. Higher rice equivalentyield signified that improved cropping pattern (Wheat - Jute -T. aman) could be appropriate in Netrakona region for rising crop productivity andcropping intensity.The higher production efficiency, land use efficiency and benefit cost ratio indicated the superiority of the improved pattern over the farmers’ practices.It can be concluded that farmers of the char area of the Netrakona region might follow wheat (var. BARI Gom-26) - jute (var. O-9897) - T. aman (var. BRRI dhan49) cropping system in char land for higher productivity and profitability.

Pesticidal plants offer valuable and sustainable options for managing Lepidopteran pests with considerable health, environmental and economic benefits in smallholder agro-ecosystem. This study Biopesticidal properties of aqueous crude extracts of tobacco (Nicotiana tabacum L.) against fall armyworm (Spodoptera frugiperda J.E Smith) on maize foliage (Zea mays L.) diets. Bio-efficacy of aqueous crude N. tabacum leaf extracts was evaluated under average room temperature at Great Zimbabwe University, Biology laboratory. The treatments were tobacco leaf extracts at four dosage levels (25 %, 33.33%, 41.67 % and 50% W/V ) and a negative control of untreated maize leaf foliage (distilled water) was used. A positive control of Carbaryl 85% WP was also used at label rates. The experiment was arranged in a Complete Randomized Design (CRD) replicated three times. Five larvae were placed into each of the experimental jars with maize foliage diets drenched into 10ml of distilled water in each treatment extract to keep the maize leaf foliage moist. Mortality for each treatment was recorded at 2 hourly intervals for 20 hours. Results showed that tobacco crude aqueous leaf extracts had Antifeedent activities against FAW larvae. The highest dose of 50% had significantly higher mean FAW larval mortalities (p< 0.05) than lower dosage (25%) and the negative control after 20 hours. However, 50% concentration was not significantly different (p>0.05) from the positive control and that of 33.33% and 41.67% dosages. The bioassay indicated that the 33.33% extract was superior in toxicity to 25% dose and the negative control but similar to higher extract doses though inferior to positive control. However, the mean mortality of 50% extract was not significantly different (p<0.05) from that of the positive control. This study recommends that 50% tobacco aqueous crude leaf extract dose to be used when controlling FAW in maize in the smallholder sector.

A UNAMID em Darfur: considerações sobre operações de paz híbridas
Authors: Aguilar Sérgio Luiz Cruz , Marquezi Marina Biagioni
Published: June 2020

A United Nations-African Union Mission in Darfur (UNAMID), estabelecida em 2007, é o atual modelo de operação de paz híbrida, conduzida pela Organização das Nações Unidas (ONU) juntamente com a União Africana (UA). Esse formato de missão trouxe uma miríade de novos dilemas para os estudos das operações de manutenção de paz. Nesse sentido, o artigo utiliza a UNAMID para apresentar algumas considerações sobre operações híbridas no campo do gerenciamento/resolução de conflitos. Baseado em fontes secundárias e primárias, o texto parte da ideia central de que, apesar de o conceito restringir a característica híbrida da operação às suas estruturas no terreno, o processo de interação das organizações parceiras se deu com muito mais propriedade e destaque nos níveis político e estratégico.

Authors: Barquero Juan Carlos Méndez
Published: June 2020

O alto nível de exposição e vulnerabilidade a desastres naturais na região da América Latina e Caribe gerou, em muitas ocasiões, um impacto direto na mobilidade humana. O deslocamento no contexto de desastres, incluindo o deslocamento transfronteiriço, é uma realidade na região. Muitos países usaram respostas ad hoc, políticas públicas e legislação migratória para lidar com esse fenômeno complexo, para o qual ainda não existe um marco jurídico internacional vinculante, especialmente do ponto de vista da admissão e permanência de pessoas diretamente afetadas e deslocadas por desastres. O artigo aborda como os países da região Latino-Americana e do Caribe utilizaram os princípios da cooperação Sul-Sul, geralmente baseados em considerações humanitárias e de solidariedade internacional, para responder a esses fenômenos, especialmente a partir do trabalho dos Processos Regionais de Consulta em Matéria Migratória

Published: June 2020

O fluxo migratório de Venezuelanos entre 2017 e 2018 afetou significativamente diversos países da América do Sul, como o Brasil, sexto maior receptor da região. No Brasil, os migrantes forçados venezuelanos chegam mais comumente por Roraima e tendem a ficar na região, uma vez que não possuem condições para seguir viagem para outros locais do país. Neste sentido, a Operação Acolhida trouxe uma solução para o dilema do Norte: O Programa Nacional de Interiorização tem auxiliado centenas de venezuelanos a se deslocarem de Roraima em busca de uma nova vida. Assim, este artigo demonstra a importância da cooperação, baseada em uma visão construtivista que reconhece outros atores, além dos estatais, para o sucesso da interiorização que começou em 2018. A pesquisa foi quali-quantitativa, bibliográfica e de estudo de caso, concluindo que a cooperação entre atores teve um importante início no ano de 2018 na Paraíba, visando a integração dos migrantes forçados venezuelanos.

Este artigo analisa a forma como o Estado brasileiro tem lidado com o fluxo migratório venezuelano, a fim de realizar uma análise crítica na construção normativa de respostas aos fluxos que se dirigem ao Brasil, por meio da confrontação desta construção estatal frente a efetividade das medidas e a adequação às prescrições internacionais de Direitos Humanos. Primeiro será analisada a migração venezuelana em Roraima, para, a partir disso, relacionar este fluxo com o contexto normativo jurídico do Estatuto do Estrangeiro, da nova lei de Migração e do Estatuto dos Refugiados, além das normas emergenciais para o tema, como a Resolução nº 126/2017 do CNIg, assim como a Portaria Interministerial nº 9. Derradeiramente, será analisado se as normas jurídicas de proteção ao migrante no Brasil são condizentes com as expectativas promovidas pelo Direitos Humanos consagrados em diplomas internacionais. O artigo apresenta a título de conclusão que o reconhecimento da grave e generalizada violação de direitos humanos na Venezuela, apesar de tardia, foi adequada aos compromissos internacionais assumidos pelo Brasil.
