Galileones vectoriales con simetría SU(2) como los generadores de los períodos de inflación primordial y expansión acelerada tardía
Authors: Bautista Torres Carlos A. , Navarro Andrés A. , Rodríguez Yeinzon
Published: November 2020

En este trabajo se demuestra que la generalización de la acción de Proca podría dar cuenta de los períodos conocidos de expansión acelerada del universo. Los campos vectoriales asociados a esta acción, denominados Galileones vectoriales, con simetría SU(2) y en disposición de tríada cósmica, permiten caracterizar un universo isótropo y homogéneo, satisfaciendo a su vez una condición necesaria para la ausencia de la inestabilidad de Ostrogradski. Por otra parte, la mencionada generalización posibilita la definición de dos fluidos artificiales: el fluido de Yang-Mills el cual corresponde a un término cinético con densidad de energía positiva, y el fluido de los Galileones vectoriales con densidad de energía negativa, ofreciendo un nuevo escenario para la descripción de la expansión acelerada del universo. En este trabajo se estudian las consecuencias cosmológicas de una de las piezas de la acción generalizada de Proca construida a partir del tensor , la cual es la versión simétrica del tensor de esfuerzos del campo de gauge . La inflación primordial se identifica con un par de puntos de silla del sistema dinámico obtenido para el modelo; lastimosamente la duración de este período es altamente sensible a las condiciones iniciales. Por otra parte, la era de expansión acelerada tardía se podría reproducir de manera satisfactoria gracias a un interesante comportamiento de autoajuste fino de las variables del sistema dinámico.

Authors: Salazar Suaza Daniela , Quijano-Abril Mario Alberto
Published: November 2020

Los humedales han sido catalogados como altamente diversos por su multiplicidad de ambientes y formas y constituyen ecosistemas únicos, de allí el interés por su conservación a nivel  mundial. En el presente estudio se buscaba caracterizar la vegetaciónacuática en 13 humedales urbanos del altiplano del Oriente antioqueño estableciendo 15 cuadrantes aleatorios de 0,5 m de lado en cada humedal, con el fin de evaluar frecuencia y cobertura. Asimismo, se determinó la distribución de la vegetación acuática por hábitos de  crecimiento ilustrada mediante un perfil. Por último, se hizo un análisis multitemporal para evaluar las presiones que estos ecosistemas han tenido a lo largo del tiempo. Se encontraron 81 especies de plantas acuáticas distribuidas en 39 géneros y 27 familias, de las cuales 41 son nativas de Antioquia. Las familias con mayor representación fueron Poaceae, Cyperaceae, Onagraceae y Juncaceae. El hábito de crecimiento que dominó fue el emergente, seguido del flotante enraizado y el flotante libre. Las presiones antrópicas observadas suponen que la urbanización, la  minería y la contaminación han perjudicado seriamente estos ecosistemas en el territorio hasta el punto de que hoy están en riesgo de desaparición si no se los incluye en el plan de ordenamiento territorial.

Authors: Walteros Rodríguez Jeymmy Milena , Castaño Rojas Juan Mauricio
Published: November 2020

Los macroinvertebrados acuáticos cumplen un rol ecológico importante en los ecosistemas acuáticos porque permiten comprender la dinámica del flujo de energía y de los nutrientes, así como de las relaciones tróficas. Son pocos los estudios asociados con microcuencas de cabeceras andinas, y, en ese contexto, el presente estudio tuvo como objetivo evaluar el efecto de la heterogeneidad de microhábitats en la riqueza de los taxones y los grupos funcionales alimenticios en los macroinvertebrados acuáticos presentes en la microcuenca Dalí, Andes centrales de Colombia. Se hicieron monitoreos bianuales entre el 2012 y el 2016 de los aspectos biofísicos mediante el índice de hábitat fluvial, así como de los macroinvertebrados acuáticos recolectados con red Surber en los microhábitats dominantes en cinco estaciones a lo largo  de la quebrada Dalí y de dos tributarios. La asignación de los grupos funcionales alimenticios se hizo con base en la revisión de la literatura especializada. En general, se registró un hábitat fluvial bien construido. Se recolectaron 34.144 organismos pertenecientes a 147 taxones que se clasificaron en seis grupos funcionales alimenticios, siendo el de los recolectores el más abundante, seguido de los fragmentadores. El sustrato rocoso fue el microhábitat más diverso. Se observaron diferencias significativas entre los microhábitats (p<0,05) y una correlación positiva de Pearson (r2 : 0,923) entre la riqueza de taxones y las condiciones del hábitat fluvial. Estos resultados confirman que la microcuenca Dalí presenta el patrón típico de las corrientes de cabecera, entornos muy heterogéneos donde la presencia de material alóctono, la heterogeneidad de los microhábitats e, incluso, las coberturas vegetales influyen ya sea positiva o negativamente en la comunidad de los macroinvertebrados acuáticos.

Se evaluaron la distribución espacial, la abundancia relativa y la estructura de tallas de Crocodylus acutus y Caiman crocodilus fuscus en Puerto Badel y Correa, Bolívar, mediante conteos mensuales nocturnos con lámparas en cuatro rutas de muestreo entre noviembre de 2015 y marzo de 2016. Se recorrieron 14 ciénagas y diez caños en una extensión aproximada de 215 km (Ẋ=14,3 ± 5,9 km). Se registraron 332 avistamientos durante el estudio, 26 de C. acutus y 306 de C. c. fuscus. La abundancia relativa para C. acutus fue de 0,11 avistamientos/km y para C. c. fuscus, de 1,26 avistamientos/km. Se encontraron poblaciones sin adultos mayores y una mayor proporción de juveniles en ambas especies. El tamaño poblacional de C. acutus osciló entre 0 y 9 individuos (n=3,89 ± 5,18) en Puerto Badel, y entre seis y 22 ejemplares (n=13,99 ± 7,99) en Correa. La población de C. c. fuscus fluctuó entre 49 y 81 individuos (n=64,80 ± 15,72) en Puerto Badel, en tanto que en Correa el valor estuvo entre 81 y 117 babillas (n=100,72 ± 15,56).
Limpieza de electrodos y reproducibilidad de medidas de impedancia eléctrica en células HeLa en solución acuosa

Published: November 2020

La espectroscopia de impedancia eléctrica (EIS) se emplea en el estudio de las propiedades eléctricas de células en suspensión. Para medir las propiedades eléctricas de materiales se utilizan dos (sistema de electrodo bipolar), tres (tripolares) y cuatro (tetrapolares) electrodos, siendo las medidas tetrapolares la mejor opción para minimizar los efectos de polarización de electrodo. Cuando se repiten las medidas de EIS en una misma muestra, se espera obtener espectros similares, sin embargo, en algunas situaciones se encuentran diferencias significativas asociadas con la baja reproducibilidad y repetibilidad. Aquí se utilizaron células HeLa dispersas en solución acuosa para evaluar también el efecto de la limpieza en el funcionamiento de los electrodos de oro. La limpieza de las superficies de los electrodos de oro se hizo por voltamperometría cíclica. Se encontró que la reproducibilidad y la repetibilidad de las medidas de impedancia aumentaba al limpiar los electrodos. Estos resultados evidenciaron que la limpieza de la superficie de los electrodos minimizó las contribuciones de la polarización de los electrodos en las mediciones. Además, se propone un modelo de circuito para describir el efecto de las superficies sin limpiar en las medidas eléctricas. Dicho modelo confirma que el efecto observado no se debió a una impedancia de polarización convencional. Más bien se trató de una polarización activa (como un potencial), la cual se presenta a bajas frecuencias y es independiente de la frecuencia de la señal de excitación.

Published: November 2020

Los drenajes de mina se consideran el principal contaminante proveniente de las actividades mineras debido al impacto que generan sobre los ecosistemas. En este trabajo se evaluó el efecto de los drenajes ácidos y neutros de minas de carbón sobre la actividad y la diversidad de las comunidades microbianas del suelo. En la primera se determinó mediante la cuantificación de las enzimas β-glucosidasa, ureasa, fosfatasa ácida y alcalina, deshidrogenasa y celulolítica, y la diversidad mediante una librería de clones en la que se identificaron 45 géneros bacterianos. Los resultados se relacionaron con los parámetros fisicoquímicos de los suelos afectados mediante un análisis de correspondencia canónica y una red biológica de los ciclos biogeoquímicos. Se encontró que, en suelos afectados por drenajes ácidos y neutros de mina, la actividad de las enzimas β-glucosidasa, ureasa y fosfatasa ácida y alcalina disminuyó significativamente, en tanto que la actividad de las enzimas deshidrogenasas y celulolíticas aumentó. Por otra parte, los nutrientes (carbono y nitrógeno), al igual que los metales (Mn, Fe, Pb, Cd y Mg) y los sulfuros, fueron las variables fisicoquímicas con mayor impacto sobre las comunidades bacterianas del suelo. Los metales y los sulfuros tienen unpapel importante en la adaptación de la población microbiana en ambientes mineros, sin embargo, cuando se utiliza enmienda orgánica, disminuye el impacto sobre la comunidad al conservarse elciclo de nutrientes.

Authors: Afify Heba M. , Darwish Ashraf , Mohammed Kamel K. , Hassanien Aboul Ella
Published: November 2020

The detection of COVID-19 from computed tomography (CT) scans suffered from inaccuracies due to its difficulty in data acquisition and radiologist errors. Therefore, a fully automated computer-aided detection (CAD) system is proposed to detect coronavirus versus non-coronavirus images. In this paper, a total of 200 images for coronavirus and non-coronavirus are employed based on 90% for training images and 10% testing images. The proposed system comprised five stages for organizing the virus prevalence. In the first stage, the images are preprocessed by thresholding-based lung segmentation. Afterward, the feature extraction technique was performed on segmented images, while the genetic algorithm performed on sixty-four extracted features to adopt the superior features. In the final stage, the K-nearest neighbor (KNN) and decision tree are applied for COVID-19 classification. The findings of this paper confirmed that the KNN classifier with K=3 is accomplished for COVID-19 detection with high accuracy of 100% on CT images. However, the decision tree for COVID-19 classification is achieved 95% accuracy. This system is used to facilitate the radiologist’s role in the prediction of COVID-19 images. This system will prove to be valuable to the research community working on automation of COVID-19 images prediction.

Objetivou-se caracterizar a base alimentar para caprinos e ovinos no Cariri paraibano. A pesquisa foi realizada nas microrregiões do Cariri Ocidental e Oriental do Estado da Paraíba, abrangendo nove municípios. A amostra obtida foi de 125 produtores, que representa 5% da população. O método de amostragem aplicado foi o probabilístico, especificamente a aleatória simples. Os dados foram tabulados em planilha eletrônica e foram efetuadas análises das variáveis qualitativas por distribuição de frequência e teste qui-quadrado. A exploração de animais para corte e comercialização do leite caprino são os principais produtos oriundos da pecuária praticada pelos produtores do Cariri paraibano. Há predominância da atividade da caprinocultura (81,6%) nas unidades de produção pecuária. 81,6% dos produtores fazem a suplementação volumosa dos rebanhos e 56,8% não utilizam práticas de conservação de forragem. As cactáceas nativas como mandacaru (Cereus jamaracu), xique-xique (Pilosocereus gounellei), facheiro (Pilosocereus pachycladus), além da palma forrageira (Opuntia sp. e Nopalea sp.) e capim-buffel (Cenchrus ciliaris) são largamente utilizados pelos produtores e para conservação de forragens, o sorgo foi o mais utilizado. Destaca-se acentuado percentual de uso de água salobra e poços artesianos. Os produtores mostraram-se dependentes da compra de insumos externos, principalmente farelo de soja, torta de algodão e farelo de trigo, requerendo assistência técnica a fim de promover a autossuficiência alimentar para seus rebanhos, consolidar opções de segurança forrageira, reduzir o uso de insumos externos, e dessa forma, contribuir com o aumento da sustentabilidade dos sistemas de produção animal na região Semiárida.

многие методы хирургического лечения анальных свищей являются недостаточно эффективными, так как многие из них негативно влияют на качество жизни оперированных пациентов в связи с развитием частичного или полного нарушения произвольного удержания содержимого толстой кишки, мочи и сопровождаются значительным процентом рецидивов свищей, требующих выполнения повторных операций. существует целый ряд публикаций и рекомендаций по лечению свищей прямой кишки, но многие из них являются противоречивыми, что делает принятие практических решений при лечении чрезвычайно сложным. В попытке достичь трех основных целей лечения (закрытия фистулы, сохранения функции сфинктера и минимизации времени заживления) за последние десятилетия были предложены различные минимально инвазивные методы сохранения сфинктера: перемещение эндоректального лоскута, использование фибринового клея и различных герметизирующих «тампонов», введение в свищевой ход стволовых клеток, полученных из жировой ткани, перевязка межсфинктерного свищевого тракта, видеоассистированное лечение и другие методы. Несмотря на столь большой арсенал предложенных минимально инвазивных технологий в лечении анальных свищей, остается много неясных вопросов о том, как адаптировать имеющиеся хирургические варианты к более сложным клиническим случаям.

Authors: OTSUKA Yuichiro , KANEITA Yoshitaka , ITANI Osamu , TOKIYA Mikiko
Published: November 2020

Background: Internet addiction and poor mental health are two pervasive problems during adolescence. This study aimed to determine whether Internet addiction and poor mental health status exhibited a bidirectional relationship in which either variable could become a risk factor for the onset of the other.
Methods: Longitudinal school-based survey with a baseline sample of 1547 students among 8 schools (10th graders) in Japan surveyed in 2015 and followed up 1 year later. The schools are located in the middle city. We assessed internet addiction using the Japanese version of the Diagnostic Questionnaire developed by Young and mental health status using the 12-item General Health Questionnaire. Regression analyses including the covariates tested whether Internet addiction was related to the onset of poor mental health among youth who had never internet addiction, and poor mental health was related to the onset of internet addiction.
Results: The incidence for Internet addiction and poor mental health during one year were 22.0% and 8.8%, respectively. Multiple regression analyses showed that poor mental health (adjusted odds ratio: 2.17 [95%CI: 1.45–3.25]) promoted new onset of Internet addiction and Internet addiction (adjusted odds ratio: 2.39 [95%CI: 1.36–4.20]) also promoted new onset of poor mental health.
Conclusion: Internet addiction and poor mental health status each increased the risk of onset of the other. Adolescents, their parents and schools need to take policies to use properly Internet.

Published: November 2020

Background: Hepatitis B is a major global health problem. It can cause chronic infections and put people at high risk of death from cirrhosis and hepatocellular carcinoma. The aim of this study was to report the epidemiological features of hepatitis B virus (HBV) infection and risk factors based on the data from Azar Cohort.
Methods: The population of this study comprised the people in the age range of 35-70 yr from Azar cohort, East Azerbaijan Province, Iran between 2015 and 2016. Based on cluster sampling, 4,949 people were selected and invited to complete the questionnaire and perform the tests. Blood samples were analyzed for serum HBV markers (HBsAg, HBsAb and HBcAb) by ELFA method. The data were analyzed using SPSS statistical software.
Results: The mean (SD) age of the participants was 49.15 ± 9.02 years. The frequency rates of HBsAg, HBsAb and HBcAb were estimated as 1.03%, 16.9% and 24.95%, respectively. There was statistically significant association between family history of hepatitis (P<0.001) and jaundice history (P<0.001) with the presence of HBsAg. There was also a positive correlation between marital status (P=0.002), history of hospitalization (P<0.001), smoking (P=0.001), dental procedures (P<0.001), foreign travels (P=0.005), occupation status (P=0.002) and the presence of HBcAb.
Conclusion: The frequency of hepatitis B in Azar Cohort was 1.03% which is a lower rate compared with other reports from Iran. The association of the population studied and the increase of public awareness in this area can probably prevent this disease.

Background: Molecular profiling techniques are the rapid detection of biomarkers in the human papillomavirus (HPV) infected cells. We aimed to measure the expression level of three cell factors including Snail1, ZEB-1, and E-cadherin in cervical cancer (CC), precancerous and healthy samples, simultaneously, to find potential biomarkers.
Methods: The expression level of the mentioned cell factors were investigated in 72 CC patients, precancerous patients, and healthy controls by using Real-Time PCR.
Results: The results demonstrated a significant reduction in the expression level of E-cadherin in cancer and precancerous cases than that in healthy cases; whereas the expression level of ZEB-1 and Snail1 were upregulated in cancer and precancerous samples. The receiver operating characteristic (ROC) analyses shows the highest AUC value emerged for Snail1: 1(95% CI: 1-1) in comparing CC and healthy groups with a sensitivity of 100.0 % and specificity of 100.0%.
Conclusion: The molecular biomarker Snail1 may be helpful to early diagnosis and prognosis of CC in the HPV-infected human populations. Considering the increased expression level of Snail1 in cancer and precancerous tissue compared to healthy tissue as well as the area under the ROC curve, Snail1 can be used for early detection of CC.

Simplified Social Mediated Crisis Communication Model during Crisis in Indonesia: A Case Study on How Customers of Indonesia Commuter Line Train Company Seek Information on a Train Delay Due to the Double Track Trial on April 12, 2019
Authors: Adi Wasono
Published: November 2020

This study explores how audiences seek information from internet and social media platforms, and considers what factors affect social media use during a crisis. The paper is based on research conducted via a survey involving 162 active followers selected from the 875,200 followers of the Indonesia Train Company: PT Kereta Api Commuter Line official Twitter account (Info Commuter Line @CommuterLine). The study proposes the Simplified Social Mediated Crisis Communication Model (SSMCC) as a variation on the original Social-Mediated Crisis Communication (SMCC) Model by Jin & Liu (2010). This variation is based on the argument that during a crisis, audiences located nearby typically rely on social media (usually accessed via a mobile phone) rather than a traditional media outlet when seeking information. This study concludes that some of the themes related to the use of social media to search for information during a crisis, and word of mouth (WOM) communication, are present in the Social-Mediated Crisis Communication (SMCC) communication model. This study also discusses the differences between the original SMCC model and the Simplified Social-Mediated Crisis Communication model proposed by the researcher. There was no evidence of an inactive social media user’s influence on information retrieval during a crisis; in addition, there is no role of traditional media as a source of information retrieval during a crisis. This research contributes to developing scientific knowledge and practices in Indonesia.
Keywords: crisis communication, social media, information search, simplified social mediated crisis communication model, social media followers

Authors: Purwaningrum Prapti Wigati , Sudana Dadang
Published: November 2020

The development of the internet world is now increasingly widespread and diverse. Information can be immediately obtained. For example, meme content is distributed via social media accounts. Memes are a form of creative ideas that are packed with graphic design and often contain insinuations about something. The purpose of this study is to uncover the signified and signifier, and speeches that appear in memes that are circulating on Fakartun Instagram account regarding the disappointment with the House of Representatives (DPR). Following a student rally in the courtyard of the DPR, concerning to the rejection of the revision of the Organization Statue of the Indonesian Corruption Eradication Commission (Komisi Pemberantasan Korupsi - KPK) and the Indonesian Criminal Code (UU KUHP), various responses emerged on social media platforms. In particular, electronic graphic designs spread from one person to another through social media platforms such as Instagram. These memes represent some people’s anxiety about the revised bills. This study relies on Roland Barthes’s semiotic approach which is the development of Ferdinand De Saussure’s semiotic theory and the illocutionary act of Searl. The results of this study suggest that the memes merged as a form of reaction to the disappointment of citizens over the revision of the bills.

Indonesia faces challenges in improving its literacy rank. In 2011, the literacy level of Indonesian fourth graders were in the 45th rank (with score 428 under 500) from 48 countries in PIRLS. In 2015 PISA’s report the fifteen-year-old Indonesian Junior High School students, occupied the 64th rank of 72 countries with score 396 under 496. To overcome this problem, the Indonesian Ministry of Education and Culture issued its Ministerial Regulation no. 23/2015 pertaining the students’ character building. This constitutes the basis of school-based literacy movement (Gerakan Literasi Sekolah). This study explores the praxis of literacy movement at one school (has implemented GLS since 2016) located in the condensed slum area of North Jakarta. Stratified purposeful sampling was deployed to select the research participants, i.e. 290 students and 20 teachers. The data were obtained from questionnaires and interviews. The result showed that not all teachers read the literacy guidelines determined by the government and their reading habit had not met the ideal number. Both teachers and students have different perception regarding to the time and frequency of schoolbased literacy activity. The fifteen minutes reading activity and reading strategies taught by the teachers were not varied. The teachers merely supervised the students while conducting the literacy activity. The students read the books they brought from home. The school-based literacy program gained the students’ literacy competence in understanding level (understand the content of the book they read) and built students’ character such as tolerance, teamwork skills, perseverance, responsibility, confidence, independence, politeness, and composure.

Authors: Megdiche Sami , Hamouda Mohamed Ben
Published: November 2020

Background: The fat-tailed Barbary sheep are the main breed of Tunisia and their morphometry has not been deeply investigated. This study aims to estimate the degree of relationship between eight quantitative measures across eight age classes, from one to eight years.
Methods: Pearson’s product-moment was calculated to evaluate the correlation among eight morphological measures, collected from 249 purebred Tunisian Barbary ewes reared under arid climate.
Result: The magnitude of pairwise phenotypic correlation among morphological traits showed a strong positive correlation (r = 0.84, P less than 0.001) between the shoulder and rump height at 6-7 years. The body weight was highly correlated to the height at rump during the first five years of age, whereas, it becomes more correlated to the heart girth when the ewe reaches its heavyweight at 5-6 years and older. The results of this study indicated that the rump height is the most correlated parameter to BW during the early life of this fat-tailed breed and are encouraging to fit live body weight from morphometric traits with accuracy.

Published: November 2020

Background: Poultry rearing systems and feeding have been the emphasis of broiler raisers to in able to meet the costumers demand for high-quality products. In this study, free range management have been introduced that allows the birds to enjoy their natural habitat while utilizing vermi meal as supplemented to commercial feeds.
Method: Evaluated the growth performance and profitability of broilers fed with different levels of vermi meal. Treatments represent T1- 100% Commercial Feeds (CF), T2- 2% Vermi Meal (VM)+98% CF, T3- 3% VM+97% CF, T4- 5% VM+95% CF. Treatment means having significant differences were subjected to Least Significant Difference at 5 % level of significance.
Result: Vermi meal did not influenced the weight gain, feed intake, feed consumption and dressing percentage of broiler chicken. However numerically, final weight and weight gain in T4 containing 5% VM was higher than T1 with commercial feed a difference of 66. 66 grams and 67.60 grams respectively. Birds of T4 with 5% inclusion of vermi meal showed higher in most parameters compared to the group fed with commercial feed. Consequently, 5% level of vermi meal had an optimum result in final weight, gain weight, feed conversion ratio, feed consumption, live weight and carcass weight.
