Authors: Samaniego Moreno Luis , Pérez Hernández Eligio , Mandujo Álvarez Enrique , Dávila Ramos Francisco
Published: July 2021

Los sistemas de tratamiento naturales se caracterizan por su bajo costo de construcción, operación y mantenimiento, así como el nulo uso de energía fósil, siendo utilizados para la remoción de cargas contaminantes en las aguas residuales. Los conocimientos que se tienen en la actualidad han llevado a proponer nuevos diseños, con la combinación de diferentes tipos de humedales artificiales, en este caso de flujo vertical para el tratamiento de las aguas residuales de la Universidad Autónoma Agraria Antonio Narro (UAAAN). Utilizando tres toneles de 0.80 m de altura, con un diámetro de 0.60 m y una capacidad de 0.20 m3 por cada tonel, a los cuales se les instaló válvulas para la toma de muestras, reguladoras de gasto, crucetas para la uniforme distribución del agua en el interior de cada tonel, de este modo tener las mismas condiciones de flujo, para mejorar la hidrodinámica del agua y ayudando al medio ambiente con la reducción de contaminantes. El tiempo de residencia teórico esperado por el sistema para una DBO de 20 mg L-1 es de 5 d, considerando una eficiencia del 80 por ciento y un caudal de 67 L d-1, mientras que para SST a 20 mg L-1, los valores esperados son de 11 d, una eficiencia del 96 por ciento y un caudal de 30 L d-1. Al realizarse el proyecto propuesto, se alcanza beneficio para el ecosistema y un aporte valioso para el desarrollo de la institución por la importancia que tiene la depuración y reutilización de las aguas residuales de la UAAAN. A grandes rasgos la construcción y diseño de un sistema natural de tratamiento es muy factible, rápido ya que los materiales utilizados son muy comunes y fáciles de adquirir.
Efecto del déficit hídrico en el rendimiento de frijol negro en el norte de Veracruz, México
Authors: Rodríguez Rodríguez José Raúl , López Salinas Ernesto , Tosquy Valle Oscar Hugo
Published: July 2021

La falta de humedad provoca en los cultivos un desbalance hídrico, que afecta su fisiología, funcionamiento, desarrollo y producción final. El efecto depende de la variedad, intensidad, duración y etapa en que se presente, pero generalmente disminuye el crecimiento, producción de materia seca, rendimiento de grano y sus componentes. La mayor reducción de producción de grano ocurre durante la floración, ya que limita la formación y llenado de vainas, y provoca aborto de flores. En el ciclo invierno-primavera de 2012 (febrero-mayo), en el Campo Experimental Ixtacuaco del INIFAP, a una altitud de 92 m; se estableció un ensayo con el objetivo de cuantificar el rendimiento de grano de frijol de 12 genotipos en un ambiente limitado de humedad, en un diseño de bloques al azar con cuatro repeticiones; la unidad experimental fueron cuatro surcos de 5 m de longitud, separados a 0,60 m, teniendo como parcela útil los dos surcos centrales. Las variables registradas fueron: rendimiento de grano (kg ha-1) y precipitación pluvial (mm). Se realizó análisis de varianza con el paquete estadístico de la UANL, Versión 2,5; las medias se compararon con la prueba de DMS (0,05). Hubo sequía en la etapa de floración y formación de vainas, lo cual redujo la producción; en estas condiciones las líneas SEN-70 y SCN-2 tuvieron la mayor adaptación y el mayor rendimiento de grano con 1053,7 y 930,79 kg ha-1; mientras Negro Papaloapan, SCN-6 y ELS-15-55 fueron los genotipos más afectados por el estrés hídrico.

Published: July 2021

La macrofauna edáfica tiene un papel muy importante en la fertilidad y estructura física de los suelos, ya que algunos de estos organismos realizan actividades cuyo impacto es positivo, por ejemplo, la regulación de los nutrientes disponibles para las plantas con lo cual se modifica el ambiente superficial y edáfico donde éstas se desarrollan, Por lo anterior se realizó un trabajo de macrofauna en dos parcelas establecidas con arboles forestales, una con árboles frutales y un acahual. Los muestreos se realizaron en los meses de julio y septiembre, la cual se determino través del índice de Shannon-Wiener. Los grupos de muestreo se dividieron en lombrices, arañas, hormigas, termitas, coleópteros, isópodos, chilopodos, diplopodos y otros. Los resultados mostraron que La comparación de la macrofauna empleando el índice Shannon-Wiener mostro que la diversidad de especies evaluadas fue baja, presentándose un índice de 0.71 para el sitio con frutales y 0.78 en el forestal lo que representó 8 y 12 especies respectivamente, así como 12 en el acahual, además de ser bajo el índice en cuanto a especies presentes también es bajo en cuanto a individuo por especie. Para asegurarse de estos resultados se estimó la equidad, la cual mostró que no existe una distribución de abundancias de especies perfectamente equitativa. Por lo cual no se pudo determinar el índice en abundancia de especies presentes en los sitios evaluados ya que la densidad de individuo por metro cuadrado fue baja. Por lo cual se puede concluir que la riqueza de macrofauna en los sitios evaluados en cuanto a número y especies presentes es baja.

Authors: Jiménez Vera Veronica , Centeno G. Erika , Sotres Fernando , Martínez Manrrique Enrique
Published: July 2021

El maíz es la base de la dieta del mexicano. De las variedades de maíz que se consumen destaca el cacahuazintle, utilizado como base en la preparación de pozole, especie de sopa al que se le agrega carne de cerdo como ingrediente, además de lechuga y rábano al momento de servirse. Actualmente, el ritmo de vida es acelerado y las personas prefieren “comidas instantáneas”. Por lo tanto, desarrollar un alimento como el pozole instantáneo, sería una buena opción para el consumidor, pues su preparación es muy tardada. Una forma de elaborarlo es por liofilización, la cual conserva las características sensoriales y nutrimentales del alimento al evitar altas temperaturas. Por otra parte, en el grupo de trabajo se ha desarrollado la deshidratación de maíz cacahuazintle para elaborar un pozole instantáneo, pero la preparación de los demás ingredientes como la carne, el rábano y la lechuga no se ha hecho. Por eso se planteó como objetivo estudiar el proceso de deshidratación por liofilización de carne, lechuga y rábano, y determinar las condiciones más favorables para la conservación de las características físicas, de textura y sensoriales, para obtener productos de alta calidad. Los resultados mostraron que las mejores condiciones de proceso fueron cuando se usaron menores temperaturas de congelación y de liofilización de los productos y las muestras con menor grosor en el caso del rábano y la carne y un área mayor en el caso de la lechuga.

Tendu fruit is one of the important forest fruit found in major part of India. Originally, plant is well known for its leaves as Bidipatta for making bidi in tribal areas of India. Since, the tendu fruit supposedly have very short shelf-life, therefore, the present study has been undertaken to evaluate the shelf stability as well as the nutritional and phytochemical potential of the fruit.The complete proximate analysis including the mineral and vitamin profiling of the pulp, skin and seeds were done. The fruit pulp was found to be especially rich in calcium, magnesium, sodium, potassium, phosphorous, thiamine, riboflavin, niacin and vitamin C, with potassium being as high as 305.52±8.94 mg/100 gm (wet basis) . The fruit skin was found to have high amounts of crude fibre, potassium, calcium, phosphorous& magnesium, whereas for seeds, the values of protein, crude fibre and oil were 7.02±0.53 % 25.13±0.41 and 5.54±0.07 % respectively. The storage stability of the fresh fruit was found to be 5 days at 25°C and 65 % R.H. During storage, pH of fruit reduced drastically with an increase in acidity value from 0.12±0.00% to 2.09±0.01 %. The reading of Browning index (A420nm) also gradually increased from 0.2257 to 0.4766. The DPPH scavenging activity, Hydrogen peroxide scavenging activity,Hydroxyl radical scavenging activity, and Reducing power assay of fruits were observed to be very high.

Published: July 2021

Forty-three phytochemicals present in Lens culinaris were evaluated through in-silico molecular docking studies for their binding affinities to the NS2B-NS3 activator-protease complex of dengue virus serotype 2 (DENV-2). Among the various compounds tested,
flavonoids (flavanols,favonols, proanthocyanidins, flavanones, flavones, and anthocyanins) demonstrated high binding affinities for the protease complex. Eriodictyol-7-O-rutinoside showed the least predicted binding energy at -9.1 kcal/mol followed by luteolin-7-O-glucoside at -8.8 kcal/mol. Glycosidic linkages appeared to enhance the binding affinities of flavonoids, aldohexoses being more potent than aldopentoses. Besides flavonoids, other classes of compounds demonstrating high binding affinities for the protease were carotenoids, phytosterols, and polyphenolic compounds like resveratrol and trans-resveratrol 3-O-b-glucoside (piceid), the latter showing predicted binding energy of -8.5 kcal/mol versus predicted binding energy of -7.2 kcal/mol for resveratrol. The 2D interactions of four high binding affinity compounds like eriodictyol, eriodictyol-7-O-rutinoside, catechin gallate, and luteolin-7-O-glucoside showed that all four compounds bound to the active site of the NS3 protease and not to the activator NS2B. Lys74 of NS3 was the common amino acid interacting with all four phytochemicals. Analysis of physicochemical properties of the compounds (Lipinski's Rule of 5) showed that the high binding affinity compounds have less than two violations, indicating that they can serve as useful lead compounds or as dengue virus serotype 2 therapeutics.

Authors: Lima Elizabeth Christina de Andrade , Souza Karlla Christiane Araújo
Published: July 2021

O artigo propõe uma interconexão entre os estudos de Cultura e Política, tomando como caso para análise a passagem do bando de Lampião pela cidade de Mossoró e de como o bando foi expulso por sua maior autoridade local, o prefeito Rodolfo Fernandes. Esse fato histórico local é revivido, todos os anos, a 13 de junho, por meio de uma peça teatral, apresentada em praça pública, o qual ajuda a reforçar e reinventar, ano a ano, tal folguedo e seus usos por parte dos políticos locais e das famílias políticas, que há anos, detêm o poder na cidade, como a família Rosado. Para tanto, pesquisamos, além da peça teatral, cordéis que contam a “saga de Lampião em Mossoró”, Jornais locais sobre os usos de políticos sobre a saga de Lampião. Observamos que tal folguedo ajuda na perpetuação não só do imaginário da cidade como “terra de valentes”, como é utilizada pelos políticos na construção de suas personas públicas.

Published: July 2021

É na teoria da folkcomunicação, proposta pelo autor Luiz Beltrão, na década de 1960, que este artigo sustenta seus aspectos teóricos e metodológicos, pois o ativismo folkmidiático cria mecanismos de leitura, identificação e ações em canais próprios, capazes de superar a pós-verdade — a distorção deliberada da realidade. Dessa forma, objetiva-se evidenciar o papel dos ativistas folkmidiáticos nas rupturas democráticas da sociedade boliviana, num contexto no qual o ciberespaço parece ser uma maneira eficaz de construir novas formas de interação social, que, em conjunto com a participação cidadã nas ruas, pode produzir ações e efeitos na realidade.

Thestudy was conducted to explore the role and feasibility of social media in advancement of aquaculture inBangladesh and its potentiality and challenges. Nowadays internet is used by 57.2% of total population ofBangladesh. Social media has become ubiquitous and social capital allows a person to draw on resources fromother members of the networks to which he or she belongs. To collect empirical data a number of qualitativeand quantitative tools such as questionnaire interviews, focus group discussion and oral history from differentstakeholders were employed. The study identified 40 communities about aquaculture techniques, systems andinformation sharing on Facebook, the most popular social media in Bangladesh. Bangladesh is a countryconsisting of different remote areas such as Haor regions, hilly regions are not easily accessible for physicalextension work of fisheries and aquaculture. Establishing the social media as a bridge between extensionorganization and fish farmers can contribute to make more profitable and sustainable aquaculture sector. Onthe other way, social media can play important role in fisheries and aquaculture research field. Based onliterature review, interview from different stakeholders the research analysis has proposed a conceptual framework for potentiality of social media in advancement of aquaculture in Bangladesh. The study has alsoidentified the challenges of establishment of social media as a tool for aquaculture extension service andprepared some recommendations. The study has found, Social media can be used to spread new techniquesand culture practices to the field. Building community network, developing community infrastructure andcommunity based fisheries management will be also easy to implement through the utilization of social media.

The present study was conducted to evaluate the effects of probiotic supplementation on theintestinal morphology of Thai pangasius (Pangasianodonhypophthalmus). The experiment was conducted in15 earthen ponds of 0.75 dec. each. Each pond contained 600 fingerlings/decimal(5.69±1.23 g) and thefeeding trial was performed for 90 days. Commercially available gut nutrient additive, Mutagen and pHFIXER (water additive probiotic) were used in the experiment. Five treatments were conducted each havingthree replicates.Treatment 1 (T1) was provided with gut probiotics, treatment 2 (T2) with water probiotics,Treatment 3 (T3) with50% gut probiotic and 50% water probiotic; Treatment 4 (T4) with prebiotic (yeast andrice starch) and 50% gut and 50% water probiotic.Treatment 5 (T5) was designed as control. Fishes were fedtwice a day at the rate of 10-5% of body weight. Samplings were carried out fortnightly where gut sampleswere collected for histology and water quality parameters were recorded. All water quality parameters werefound to be favorable for fish culture. Histological analysis of the gastrointestinal tract revealed that foldlength, width and enterocyte height were significantly larger (p<0.05) in fish of T3 and T4compared to thoseof T1, T2, T5. Thus, probiotic supplementation can improve the intestinal morphology of Thai pangasiuswhich may increase the nutrient absorption in fish and thereby increase the digestion capacity.

The present study was conducted to evaluate the effects of climate induced salinity on histoarchitecture of liver, kidney and ovary tissue of female striped gourami (Trichogaster fasciata) exposed tothree sub-lethal concentrations (3, 6 and 9 ppt) of crude salt along with a control group (0 ppt) for a periodof 30 days. The 96-h LC50 value of crude salt for striped gourami was previously estimated as 11.107 ppt. Toconduct the experiment 12 plastic tanks each having 70L water holding capacity were used for the fourtreatments with three replications for each. Water exchange was done on every 10th day and crude salt wasused to maintain desired salinity. Several histopathological changes were observed in fish liver, kidney andovary exposed to different concentrations of salinity. Increasing necrosis, hemorrhage, hepatic rupture,melano-macrophage cells, degenerated cell and vacuums in the liver tissue were found in salt water treatedgroups. Similarly, a number of changes such as, vacuole, cellular degeneration, hemorrhage, disintegratedglomeruli, destructed renal tubule and extensive vacuolein were observed in the kidney tissue of salt watertreated groups. Degenerated oocyte, inter-follicular space, disrupted oocytes, etc. were observed in ovarywith increasing concentration of salinity and time of exposures. Physiological and metabolic dysfunctionsmight have happened to female stripped gourami due to changes in vital internal organs like liver, kidney andovary. Therefore, the present research further suggested that climate induced salinity intrusion is capable ofstressing freshwater fishes resulting in deformities of liver, kidney and ovary.

Growth pattern of pama croaker Otolithoides pama population in the Bay of Bengal was determinedas the corollary of relationships between standard length (SL) and total length (TL), the two most prevalentlyused linear dimensions of fin fish species. Monthly pama croaker samples were collected from the industrialfisheries in the Bay of Bengal. The length-length relationship was constructed algebraically in the form ofy=a+bx. Relationships between SL and TL for male, female and unsexed populations were separatelyestablished. Sex ratio between male and female did not deviate from the parity (?2 test; p>0.05). The SL andTL ranges of male were 7.2-22 cm and 9.5-28 cm respectively, and the SL and TL ranges of female were6.8-20 cm and 8.4-25.7 cm respectively. Intercept and slope varied monthly in all length-length relationshipsregardless of gender categories. The generalized SL-TL relationships of male, female and unsexedpopulations were TL=1.214SL+0.761(R=0.989), TL=1.212SL-0.770(R=0.990) and TL=1.203SL+0.904(R=0.987) respectively. The correlation coefficients of both monthly and generalized regression analyses ofall sex types were very high (R?0.852) which explained that the relationships between the two lengthdimensions were strongly correlated. The growth corollary appeared both as isometric and allometric formonthly populations. Allometric growth was apparent in July, August and September in all gender types,while isometric growth was deduced in other months. This study would be useful for future research in orderto make comparisons with the relevant aspects of O. pama population between years and locations in the Bayof Bengal.

Marine fish is a major source of Omega-3 fatty acids (Eicosapentaenoic acid, EPA andDocosahexaenoic acid, DHA), which are now recognized worldwide as a key factor in human health. Thepresent study was conducted to depict the status of marine fish consumption in three districts (namely Feni,Lakhsmipur, and Noakhali) of greater Noakhali district, Bangladesh using a questionnaire survey in 240households during the month of May-June, 2018. Almost all the households (96%; n=230) consumed marinefishes. Price, availability, presence of inter-muscular bones, and characteristic fishy smell were the majorbarriers to marine fish consumption in the studied area. The average quantity of fresh and dried marine fishconsumed was 53.35 g/capita/day and 3.71 g/capita/day, respectively in greater Noakhali. Marine fresh fishconsumption in the three districts differed significantly (p<0.001). The highest (80.20±32.72 g) and thelowest (40.02±27.90 g) amount of marine fresh fish consumption were observed respectively, in Lakhsmipurand Feni district and the highest (4.19±7.47 g) and the lowest (3.47±4.87 g) amount of dried marine fishconsumption were observed respectively, in Feni and Noakhali district. About 32% of consumers consumedmarine fresh fish 3 to 6 times in a week whereas 46% of consumers consumed dried fish once in a month.Consumers belonging to high-income households consume more marine fish (57.11 g) than the low-incomehouseholds (49.33 g). Harpadon nehereus, Tenualosa ilisha, Otolithes cuvieri, Polynemous paradiseus, Mugilcephalus, Oxyurichthys microlepis, and Sillago domina were among the most frequently consumed marinefishes in the studied areas. About 76% of respondents perceived eating marine fish was good for health.Increased availability, lower price and creating awareness on health benefits may lead to increasing marinefish consumption among local people in the region.

A checklist of the marine fishes of Bangladesh is presented with their scientific, common andBangla or local names. The global IUCN Red List catagories of these species are also provided. Thisinventory of the marine fish species is compiled from different major and valid published scientific papers,reports and books published within last 50 years from 1970 to 2020. The directory covers a total of 740species belonging to 389 Genera of 145 Families and 30 Orders. Among the fish species, 53.38% areexclusively marine and 46.62% are found in both brackish and marine water. Besides, 296 species of fishesare reef associated and 204 of these are recorded from the Saint Martin’s Island. Further, 271 species ofbrakishwater and/or marine fishes are commonly observed in the Sundarbans mangrove ecosystem and itsadjacent sea area. About 7% of the total marine fishes of Bangladesh are identified as threatened as per globalIUCN Red List. However, the conservation status of the marine fish species of Bangladesh has not yet beenassessed locally by IUCN which is essential. The updated checklist will constitute the reference inventory ofmarine fishes of the coastal and maritime area of the country.

Background: Pre-eclampsia with hyperuricemia is a complication of pregnancy associated with fetal mortality and morbidity. The main complications are preterm delivery, low birth weight and intrauterine demise of the fetus along with higher rate of cesarean section.Objective: To compare fetal outcome in pre-eclampsia with hyperuricemia and with normal uricemic controlMaterial and Methods: Study was conducted at department of the Gynecology “B” Hayatabad Medical Complex Peshawar from 1st August 2016 to 31st July 2017. Patients with pre-eclampsia were divided in two groups “A” and “B”. In group “A” patients with serum uric acid level > 6mg/dl and in group “B” patients with uric acid level of < 6mg/dl were included. The low birth weight, preterm birth, rate of cesarean sections and intrauterine death were observed in the two groups. Results: Among the 60 patients with hyperuricemia 34 (56.66%) babies born with low birth weight, rate of cesarean section was 53.33% (32), pre-term delivery 48.33% (29) and intrauterine deaths 6.66% (4). While in 60 patients with normal uricemic control 7 (11.66%) babies born with low birth weight, rate of cesarean section was 13 (21.66%), pre-term delivery 16 (26.66%) and intrauterine deaths 0 (0.00%).Conclusion: Increased uric acid level is a poor predictor for fetal outcome in terms of low birth weight, preterm birth, rate of cesarean sections and intrauterine death.
