Os Sistemas Convectivos de Mesoescala (SCM) contribuem substancialmente para a estação chuvosa da Região Nordeste do Brasil. Variações na Temperatura da Superfície do Mar (TSM) dos Oceanos Pacífico Equatorial e Atlântico Tropical impactam diretamente na intensidade dos SCMs que por sua vez influenciam na qualidade da estação chuvosa. Neste sentido, identificou-se em um acervo de 41 anos de dados de precipitação diária de 31 postos pluviométricos localizados sobre o Estado da Paraíba, os SCMs, afim de conhecer a influência do El Niño, La Niña e as fases do Dipolo de TSM no Atlântico Tropical (DTAT) sobre os sistemas precipitantes em mesoescala. Os SCMs são mais numerosos em anos de DTAT negativo e de El Niño. Porém, quando subtraídos os episódios fracos de El Niño, o número de sistemas se mantém abaixo dos observados em anos normais. Contudo, os SCMs são mais intensos nos episódios de DTAT e de La Niña quando comparado com anos normais.   A B S T R A C T Mesoscale Convective Systems (MCS) contribute substantially to the rainy season in the Northeast of Brazil. Variations in sea surface temperature (SST) of the Equatorial Pacific Ocean and the Atlantic directly impact the intensity of MCSs which in turn influence the quality of the rainy season. In this sense, it is identified in a collection of 41 years of daily rainfall data from 31 rain gauge stations located on the State of Paraíba, the MCSs, in order to determine the influence of El Niño, La Niña and the phases of the SST Dipole Tropical Atlantic (DTAT) on the mesoscale precipitation systems. The MCSs are more numerous in years of negative DTAT and El Niño. However, when subtracted from the weak El Niño events, the number of systems remains below those observed in normal years. However, SCMs are more intense episodes of DTAT and La Niña compared to normal years.   Key word: convective system mesoscale, El Niño, La Niña, dipole phases

Z dotychczasowych badań wynika, że – poza lingwistycznymi i wizualnymi środkami wpływu – na odbiór newsów plotkarskich w istotny sposób oddziałuje również społeczna praktyka plotkowania, która obniża uważność odbiorców i zmienia ich oczekiwania względem prawdziwości przedstawianych wiadomości.
Aggressive rhetoric in Croatian post-election political discourse
Authors: Runjić-Stoilova Anita , Jović Andrea
Published: March 2021

Aggressive rhetoric in Croatian political discourse became particularly prominent during the parliamentary election in 2015. A deep polarization of society yielded a new political option, one of the strongest since the beginning of Croatian independence in 1990. After the great election success, MOST got the opportunity to form the new Croatian Government either with HDZ or SDP, the two most influential parties in Croatia. This situation caused enormous tension in the postelection period and consequently intensified the politicians’ aggressive rhetoric. The aim of this study is to describe, interpret and explicate linguistic and rhetorical devices which contributed to the aggressiveness, and ultimately conclude which of the political options listed above is the most aggressive.
Conceptual silencing as a rhetorical tool. A cognitive lexical semantics study of the lexical item Europe
Authors: Wilk Przemysław
Published: March 2021

Taking a cognitive lexical semantics perspective, the article introduces the concept of conceptual silencing as a rhetorical tool. Understood as a process of conceptual dissolution of meaning to offer a more coarse-grained sense of an expression, conceptual silencing is demonstrated to have a potential rhetorical value in that it allows for more opaque reproduction of ideology. From a cognitive linguistic standpoint, the process of conceptual silencing hinges upon a polysemous nature of a lexical item and boils down to triggering a given sense of a given lexical item in a given context. To illustrate the workings of conceptual silencing, the article reports on a case study of the lexical item Europe in the Guardian press discourse. It is demonstrated that the ultimate effect of conceptual silencing is silencing the ‘European Union’ senses under the guise of the lexical item Europe.

En frutales, la productividad difiere entre huertos debido a la condición particular del estatus nutrimental de los árboles, fertilidad del suelo, portainjerto, sanidad del cultivo y manejo agronómico. El objetivo de esta investigación fue comparar el rendimiento, calidad y comportamiento poscosecha de frutos de aguacate ‘Hass’ en dos huertos con diferente manejo de la fertilización. El primero se ubicó en Valle de Bravo y el segundo en Villa de Allende, Estado de México. La evaluación se realizó en 2017. En cada huerto se midió el rendimiento, calidad, comportamiento poscosecha y extracción de nutrimentos por los frutos. Además, se diagnosticó el estatus nutrimental del árbol y la fertilidad del suelo. Los frutos del huerto de Valle de Bravo superaron a los de Villa de Allende en rendimiento, peso, longitud, diámetro y concentración y densidad de aceite, sin embargo, presentaron menor firmeza y pérdida de peso. Los aguacates de Valle de Bravo tuvieron mayor concentración de K, S, Zn y B, los de Villa de Allende concentraron más Ca, Fe, Cu y Mn. En Valle de Bravo los árboles mostraron deficiencias de Ca, S, Cu, Mn, Zn y B, mientras que, en Villa de Allende, los elementos deficientes fueron K, S, Zn y B. En conclusión, el mayor rendimiento de fruto obtenido en el huerto de Valle de Bravo se relacionó con el mejor estatus nutrimental de los árboles y mayor fertilidad del suelo.

Published: March 2021

La contaminación de aguas superficiales y subterráneas por herbicidas como la atrazina ocurre por lixiviación a través del perfil del suelo. El objetivo del estudio fue evaluar la movilidad de atrazina en parcelas dedicadas al cultivo de maíz, cada una con un tipo de suelo distinto ubicadas en los municipios de San Nicolás Buenos Aires (Regosol) y Los Reyes de Juárez (Calcisol), Puebla, México. Se realizaron experimentos de desplazamiento en columnas empacadas de suelo (8.5 cm de diámetro y 30 cm de longitud). Sobre cada columna se aplicó una concentración acuosa de 6.25 g L-1 de atrazina (Gesaprim®). Se empleó, primero, un volumen de poro de una solución reconstituyente del suelo (sin atrazina) y posteriormente, se aplicaron 30 volúmenes de poro de agua de riego que contenía atrazina. Se analizaron los lixiviados y tres profundidades de las columnas de suelo (0-2 cm, 2-10 cm y 10-20 cm, respectivamente). Los resultados de correlación de Pearson mostraron que la materia orgánica, textura y la capacidad de intercambio catiónico fueron las características fisicoquímicas del suelo que afectan a la movilidad de la atrazina. La atrazina presentó un coeficiente de retardo de 1.08 en Regosol y de 1.03 en Calcisol. El transporte del herbicida fue nueve veces mayor velocidad en el Regosol con respecto al Calcisol. La atrazina se mantuvo retenida en una mayor cantidad en los dos centímetros de las columnas de suelo. El porcentaje de masa degradada de atrazina fue de 94% para el Regosol y 69% para el Calcisol.

Authors: Fonseca Varela Mariana , Chalita Tovar Luis Eduardo
Published: March 2021

En los últimos años la producción de destilados de agave en México, dentro de ellos el mezcal, se ha vuelto cada vez más importante. En el periodo 2013-2019, su valor ha aumentado a una tasa promedio anual de 19.76%. Tal comportamiento ha sido impulsado por los precios del producto y la creciente demanda nacional e internacional, respecto a este último concepto de 2017 a 2018 las exportaciones de mezcal crecieron a una tasa de 34.4%. Lo anterior, ha llevado a que cada vez más unidades productivas se vinculen a la cadena de valor del agave, como ha sido el caso del municipio de Caltepec, Puebla, cuya población se encuentra en pobreza y vive de la agricultura. En este sentido, es necesario analizar las oportunidades que pudiera generar la producción de agave y mezcal, para proveer oportunidades productivas que busquen mejorar la economía municipal. Con base en lo anterior, se elaboró una evaluación financiera a partir del año 2020 con un periodo de planeación de ocho y 15 años a partir de la puesta en marcha del proyecto. Los hallazgos de la investigación sugieren que ambos tipos de oportunidades de negocio son factibles financieramente, al obtener un valor actual neto de $34 074.09 y $1 911 792.96, respectivamente. Por lo que pueden servir como alternativas potenciales a mejorar el bienestar de distintas unidades productivas de la región, con ello coadyubando a mitigar la pobreza local.

Published: March 2021

En México existen más de 358 especies de plantas, de las que únicamente se consumen hojas y tallos tiernos, conocidas como ‘quelites’. Dado el potencial productivo, económico y nutrimental de estas especies, entre ellas la verdolaga, es preciso determinar factores que afecten su crecimiento y desarrollo. La verdolaga constituye una alternativa como hortaliza debido a su potencial nutrimental, productivo y económico; su rendimiento estará determinado principalmente por el desarrollo de tallos y hojas, por lo que el conocimiento generado sobre los factores que afectan su crecimiento resulta de gran importancia agronómica. En la presente investigación se evaluó el efecto de tres densidades de siembra en el crecimiento de la verdolaga. Se consideraron los datos correspondientes a tres etapas fenológicas del desarrollo de la verdolaga (desarrollo vegetativo, madurez vegetativa y floración) para determinar si existían diferencias significativas entre las medias de los tratamientos evaluados mediante un Anova y para determinar si existía homogeneidad de varianza se llevó a cabo el método Levene. Las plantas sembradas a una densidad de siembra alta (295 plantas m-1 lineal) tuvieron mayor altura, menor diámetro de tallo, menor número de hojas (grandes y chicas) y menor desarrollo de las ramas (longitud de ramas) en comparación con aquellas sembradas en densidades de siembra media y baja (250 y 134 plantas m-1 lineal); sin embargo, el número de hojas en las ramas depende del nivel del dosel donde éstas se localicen. La densidad de siembra es un factor que contribuye a determinar el crecimiento de la verdolaga ‘Chapingo”.

Published: March 2021

Triboelectric nanogenerators are shown a recent development in the energy field in various applications powering sensors to biomedical applications. The research development of tribogenerators is trending in the renewable energy area as it can harness waste mechanical energy due to the friction. Studies have shown various mathematical modeling done on the triboelectric principle based on Gauss electric field principle. Triboelectricity generation due to contact electrification depends on various factors that include the surface charge density, materials, the geometrical features of the tribo pairs, the mode of operation in terms of velocity etc. The significance of nanomaterials in the generation of triboelectricity is a research area where polymers have shown good results. In this study, a detailed computational and numerical simulation is done on selected pairs of triboelectric material combination chosen from the triboelectric series. Computational simulation is performed using Comsol Multiphysics to evaluate the output performance in terms of Voc and Qsc. Numerical simulation is performed using MatLab to evaluate the output performance current, power, voltage with respect to time for selected input parameters. The numerical performance of the device is validated by the experiments. The numerical method adopted will be a useful tool for determining the output characteristics of any triboelectric pairs.

Biomedicina y donación de órganos, debates antropológicos
Authors: Brito Alvarado Xavier
Published: March 2021

El presente artículo pretende cartografiar a partir de una revisión bibliográfica, primordialmente procedente de la antropológica médica; los discursos biomédicos sobre las donaciones de órganos y la construcción de una subjetividad en los receptores de órganos. En la donación se conjugan el conocimiento anatómico, el discurso biotecnológico, las experticias del personal médico y los contextos culturales sobre las donaciones, que en muchos casos conlleva a la creación de escenarios tensionantes entre los sujetos inmiscuidos. Sin embargo, la presencia de una economía subterránea, de manera especial en países pobres, ha puesto precio a los órganos, lo que los convierte en productos comerciales, dejando a un lado el sentido altruista de las donaciones. El objetivo de este artículo es reflexionar sobre las donaciones de órganos no solo como un nuevo espacio de la subjetividad, sino como en el capitalismo esta acción altruista se ha convertido en intercambio comercial.

Authors: S  Velanganni  , P Sivakumar  , S Miltonprabu
Published: March 2021

The current investigation intended to evaluate the effect of Benzophenone-3 (BP-3) at the environmentally relevant concentration (44 μg/L) in the gills of Danio rerio through evaluating oxidative stress markers and histopathological analysis. The adult Zebra fish was exposed to BP-3 at environmentally relevant concentration for 45 days. During the experimental period of 15, 30 and 45 days, lipid peroxidation markers like thiobarbituric acid reactive substances (TBARS) and Hydrogen peroxide (H2O2), antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), Glutathione peroxidase (GPx) and non-enzymatic glutathione (GSH) in the gill and histology of gill were analyzed. The activity of TBARS and H2O2 was found to be significantly higher meanwhile the activities of antioxidant enzymes viz., SOD, CAT, GPx and Glutathione (GSH) level were found to be significantly reduced in the gill of BP-3 treated fish for 30 and 45 days. Additionally, the morphology of gill also showed several abnormal changes in their morphology when compared to control. BP-3 exposure for 15 days elicited only mild alterations in the biochemical and histopathological variables when compared to 30 and 45 days exposure. Further, the values were also non-significant when compared to the control fish. These results demonstrated that the treatment of BP-3 at environmentally relevant concentration could prominently alter the respiratory physiology and metabolism of the gills of Danio rerio.

Volvovaginitis is an inflammation of the vagina that can result in discharge, itching and pain. This study determined the occurrence of vaginal infection (volvovaginitis) among female students in Ogun State College of Health Technology, Ilese-ijebu. A validated questionnaire was used to obtain information on socio-demographic characteristics of fifty selected students and sterile swab stick was used to collect their vaginal swabs. MacConkey and Chocolate agar were used to culture the microorganisms and data were analyzed using frequency counts, percentages, correlation, and Chi-Square. The result showed that majority of the students were in the age range of 21-25yrs and the hygienic practices of the students were poor because majority do not have access to clean water, about 45% spread their underwear in untidy environment after washing, 27% of them used any material (clothe, tissue paper, cotton wool) during their menstrual period if they could not afford sanitary pad at that moment and 15% confessed that they can wear their pants for two or three days. The isolated microorganisms showed the growth of Candida spp, Staphylococcus aureus, Klebsiella and Escherichia coli in 40%, 22% and 2% of the female students respectively. Chi-square showed a significant association between age and Candida spp (p=0.012), and Escherichia coli (p=0.004) while correlation shows a significant relationship between hygienic practices and identified microorganisms because unclean water was related to Klebsiella (p= 0.311) while dirty underwear have a significant relationship with S. aureus (p= 0.121). Conclusively, this study shows the prevalence of vaginal infections amongst female students in the college and could provide important epidemiological data on vaginal infection for future population-based studies.

Published: March 2021

Introduction: Pleomorphic adenomas are the most common non-malignant neoplasms of salivary gland tumours that present mixed histopathological patterns. The purpose of our study was to report an unusual case of a pleomorphic adenoma which was located in the upper lip that had been initially considered as cyst. Case report: The patient was a middle aged man who had a painless, slow-growing swelling in the upper lip. At first, the round-shaped and mobile mass was considered as cystic lesion. However during the operation, it was discovered instead of a cyst, an encapsulated solid tumour that demonstrated both epithelial and mesenchymal cells in histopathology and the diagnosis of pleomorphic adenoma was set. One year postoperatively the patient had no recurrence of tumour. Conclusions: Occurrence of intraoral lip swelling could be attributed, even rarely, to benign mixed tumours. Despite its nonmalignant features, these masses have a relatively low but still existing risk for recurrence or malignant transformation and thus in similar cases a systematic follow-up should be performed even years after surgery.

This research has been conducted in Nertiti locality of central Darfur State during 2020/2021 cropping season in order to enhance rainy wheat productivity through technology validation and dissemination. Farmers Field School was established with 25 farmers (5 men and 20 women). On-station demonstration farm was conducted with an area of 2feddan. Improved wheat variety Zakia (1feddan) grown versus Nillin (0.5 feddan) and local (0.5 feddan) to evaluate crop performance and potentiality. Clustered random sampling technique applied. Evaluation questionnaires developed randomly to 20 farmers to know farmers perceptions on wheat performance and productivity. Farmers subjected to farming training in wheat technologies of land preparation, sowing date, seed preparation, seed dressing, weeding, water harvesting, soil conservation, pests and diseases control, seed production technologies and harvest and post harvest technologies. Results showed that excessive rainfall variation during reproductive growth affect wheat yield by 32%. Socioeconomic characteristics and frequency distribution of farmers revealed that 80% of FFS participants were educated and 20% illiterate. 10% of farmers have farm size less than 1 feddan, 50% have 1-2 feddan, 30% have farm size range between 3-4 feddan and 10% have more than 4 feddan. Agriculture is the main source of income (80%), while 20% traders and pity trading. Results noted that 90% of FFS participants have no extension services and only 10% have.40% of respondent’s have experience in wheat production, while 60 have no experience.40% of participants perceived that improved wheat is resistant to water logging and high rain fall, 20% resist to insects, 30% high yielded and 10% said low yielded. Crop productivity trend showed that highest grain yield was obtained by improved Zakaia (655 kg/feddan) followed by Nillin (626 kg/feddan), while the lowest yield gained by local (424 kg/fedan). It was also recorded that improved Zakia exceed local and Nillin yields by 54% and 5%, respectively. Partial crop budget result revealed that all treatments were financially gave positive net returns.

The aim of this study is to monitor the effect of two starter cultures on some chemical and sensory properties of industrially produced Macedonian traditional sausage. The research covered three variants: Variant 1: Control variant (conventionally produced Macedonian traditional sausages using nitrite salt and powdered acerola); Variant 2: Macedonian traditional sausages where the basic formulation was enriched by addition of starter culture CS-300 (Staphylococcus carnosus ssp. utilis + Staphylococcus carnosus) in combination with Swiss chard powder and powdered acerola; Variant 3: Macedonian traditional sausages where the basic formulation was enriched by addition of starter cultures CS-300 (Staphylococcus carnosus ssp. utilis + Staphylococcus carnosus) and BLC-78 (Pediococcus acidilactici + Staphylococcus carnosus) in combination with Swiss chard powder and powdered acerola. Starter cultures have a positive effect on changing the pH value of sausages, which creates favorable conditions for the development of the desired microflora. In the sausages from variant 2 the value for water activity is constant, and the largest decrease was determined in the variant 3. Nitrate-reducing bacteria in combination with a natural source of nitrates (Swiss chard powder and leek) are a suitable substitute for nitrite salt, thus eliminating its negative effects on consumer health. According to the obtained results, with the use of the starter culture CS-300 good quality of the sausages is achieved. At the same time a safe product is obtained where the use of nitrite salt is completely eliminated.

Antibiotics are the most widely injudiciously used drugs for therapeutic purposes throughout the world. This study aimed to detect cephalexin residue after discriminate and indiscriminate administration of cephalexin antibiotic in broiler. Eighteen broiler chicks, DOC (Cobb-500) were collected & reared for up to 31 days. The chicks were randomly divided into three groups namely control group (Group-A), discriminate cephalexin group (Group-B) and indiscriminate cephalexin group (Group-C). Each group consists of 6 birds. In this investigation, only a detectable level of antibiotic residues was found in indiscriminate group of poultry. A total of 72 samples were investigated by the TLC method. The overall residue of cephalexin found in indiscriminate group as in liver (100%), kidney (83.33%), thigh muscle (25.00%), breast muscle (8.33%), fat and spleen (66.67%) respectively. The final average body weight were recorded highest in indiscriminate antibiotic group (1804.17 ± 73.92gm) followed by discriminate group (1741.33 ± 63.63gm) and control group (1453.33 ± 26.39gm). The body weight was found significantly (p<0.05) higher in the antibiotic treated groups. The hematological parameters such as Hb, PCV and TEC values of treatment groups showed significantly (p<0.05) lower, while PCV did not show any significant difference compared to the control group. Overall, the present study documented the widespread abuse of cephalexin and failure to implement the recommended withdrawal period will undeniably lead to deposition of residues in broiler tissues.

5‐fluorouracil (5-FU), a pyrimidine analogue anticarcinogenic agent, is widely used in the solid tumors treatment. Use of the 5-FU causes cardiotoxicity. Our aim in this study investigations effects of Quercetin and Rutin on ECG parameters in the 5-FU-induced cardiotoxicity in rats. In the present study used male rats. Rats were divided randomly to eight group. The control group was given intragastric corn oil for 14 days. The 5-FU group rats were given ig corn oil for 14 days and injected intraperitoneal the single dose of 5-FU(50 mg/kg) on the eleventh day. The Q50+5-FU and Q100+5-FU groups were given ig 50 mg/kg and 100 mg/kg Q for 14 days, respectively and these groups were injected single dose of 5-FU(50 mg/kg) on the 11th days of Q application. The group Q100 was Q(100 mg/kg-ig) for 14 days. The Rutin50+5-FU and Rutin100+5-FU groups were injected ig 50 mg/kg and 100 mg/kg of the Rutin for 14 days, respectively. These groups were injected single dose of 5-FU(50 mg/kg) in the 11th days of Rutin application. The Rutin 100 group was given Rutin(100 mg/kg-ig) for 14 days. In the end of experimental application recorded to ECGs of the rats. 5-FU administration rats were observed that it was caused sinus tachycardia and ST elevation. Also, in the 5-FU group QRS segment was shorter and the duration and amplitude of the P was different from other groups. In both doses of Q and Rutin were prevented these changes and our findings were seen the consistent with the literature.
The irreplaceable role of coronavirus carriers in its transmission and in second wave of infection
Authors: Vladimir Zajac
Published: March 2021

At present, the fight against the virus is focused on early diagnosis and vaccination, which are indispensable and essential methods in finding a viable solution. However, these are virtually defensive reactions. The virus reigns. We have turned the parasite into the king, practically having become its hostages. The new coronavirus pandemic is not over yet. The second wave has hit and is in full swing, with the third wave lurking around the corner or having already erupted. In most parts of the world, the second wave has proven to be much stronger than what we saw in spring 2020. There is a general perception that the definition of the second wave cannot be adequately expressed as there remains a lot of uncertainty and ambiguity, even among the scientific community. However, this phenomenon needs to be explained as it will help clarify the pandemic of the new coronavirus.

This study aims to determine the performance yield component of sweet corn and weed density due to different kinds of fertilizer treatments. This study uses a randomized complete block design (RCBD) in factorial patterns with two factors. The first factor is biofertilizer-Arbuscular mycorrhiza fungi (biofertilizer-AMF) which consists of four levels, namely without biofertilizer-AMF (A0), biofertilizer-AMF 5 g/planting hole (A1), biofertilizer-AMF 10 g/planting hole (A2), biofertilizer-AMF 15 g/planting hole (A3). The second factor is cow manure fermented consisting of three levels, namely without cow manure (B0), cow manure 5 tons ha-1 (B1), cow manure 10 tons ha-1 (B2) with 3 replications so that there are 36 experimental units. The variables observed in this study were: cob length (cm), cob diameter (cm), number of seed rows, cob weight with husk (g), cob weight without husk (g) productivity of sweet corn plants (ton ha-1) and kinds of weeds and their absolute density. The results showed that the highest average corn crop productivity was obtained in the treatment without biofertilizer-AMF and cow manure fermented 10 tons ha-1 (A0B2) as 8.52 tons ha-1. If the combination of treatments contained biofertilizer-AMF and cow manure fermented, the highest average productivity of sweet corn was obtained in the treatment of biofertilizer-AMF 5 g/planting hole and cow manure fermented 10 tons ha-1 (A1B2) as 7.19 tons ha-1. The highest weed density from broadleaf is H.capitata (34.167%), from grasses is I.cylindrica (32.432%) and from sedges is Cyperus sp (30.21%).
