Vermicomposting of aquatic weeds: A quick review
Authors: Najar Ishtiyaq Ahmed 
Published: September 2017

Aquatic plants play an important role in ecosystem functioning and services but they can also be deleterious if present in excess. The different anthropogenic activities result in accumulation of nutrients in aquatic ecosystems leads to eutrophication with massive weed growth and associated diverse adverse effects. Effective control/management of weeds in different aquatic systems is not only difficult but of short duration. The commonly used methods to manage/control the aquatic weeds are biological, chemical and mechanical, in addition to habitat manipulation. However, these methods can be highly disruptive causing adverse environmental effects and are relatively inefficient. On the other hand different species of earthworms can feed on wide range of weeds and convert them into stable product called vermicompost, rich in plant nutrients. Among different aquatic weeds the most extensively vermicomposted weed is water hyacinth (Eichhornia crassipes (Mart.) Solms), using different earthworm species. Among different earthworm species used for vermicomposting of aquatic weeds, Eisenia fetida (Savigny) is the most commonly used species. Vermicomposting is an efficient ecobiotechnological process that converts the aquatic weeds into nutrient rich material that can acts as suitable plant growth media for sustainable agroecosystems. Further large scale utilization of aquatic weed based vermicompost in horticulture can solve their management and disposal issues along with restoration of organic matter and nutrient depletion at low input basis.

Abstract
In this paper, the comparison of turbulence models for fluid flow past single sphere under supercritical conditions is reported. Firstly, Dixon et al.’s models [1], which are under non-supercritical conditions, were used as benchmarks to validate the simulated results. Two turbulence models namely RNG k-ε and SST k-ω models parameters were fine-tuned accordingly in order to obtain almost comparable results generated by Dixon et al.’s models [1]. The simulation works were then extended to simulate flow of supercritical carbon dioxide. The second part of this paper, therefore, presents a comparative study of the turbulence models i. e. standard k-ε, RNG k-ε, realizable k-ε and SST k-ω models. This study emphasises on the predictions and evaluations of the velocity profiles at different flow regimes namely recirculation, recovery and near-wake. Simulations were carried out to determine the velocity profiles at subcritical and supercritical conditions by varying Reynolds numbers (2000 and 20,000), pressures (65 and 80 bar) and temperatures (283.15 and 308.15K). Simulation results indicate that the predicted results are consistent with the literature data. Interesting flow features were identified for all the simulations. The results of this study also reveal that the SST k-ω turbulence model was able to better capture the flow characteristics near-wake of the sphere.

Spatiochromatic Interactions between Individual Cone Photoreceptors in the Human Retina

Published: September 2017

A remarkable feature of human vision is that the retina and brain have evolved circuitry to extract useful spatial and spectral information from signals originating in a photoreceptor mosaic with trichromatic constituents that vary widely in their relative numbers and local spatial configurations. A critical early transformation applied to cone signals is horizontal-cell-mediated lateral inhibition, which imparts a spatially antagonistic surround to individual cone receptive fields, a signature inherited by downstream neurons and implicated in color signaling. In the peripheral retina, the functional connectivity of cone inputs to the circuitry that mediates lateral inhibition is not cone-type specific, but whether these wiring schemes are maintained closer to the fovea remains unsettled, in part because central retinal anatomy is not easily amenable to direct physiological assessment. Here, we demonstrate how the precise topography of the long (L)-, middle (M)-, and short (S)-wavelength-sensitive cones in the human parafovea (1.5° eccentricity) shapes perceptual sensitivity. We used adaptive optics microstimulation to measure psychophysical detection thresholds from individual cones with spectral types that had been classified independently by absorptance imaging. Measured against chromatic adapting backgrounds, the sensitivities of L and M cones were, on average, receptor-type specific, but individual cone thresholds varied systematically with the number of preferentially activated cones in the immediate neighborhood. The spatial and spectral patterns of these interactions suggest that interneurons mediating lateral inhibition in the central retina, likely horizontal cells, establish functional connections with L and M cones indiscriminately, implying that the cone-selective circuitry supporting red–green color vision emerges after the first retinal synapse.SIGNIFICANCE STATEMENTWe present evidence for spatially antagonistic interactions between individual, spectrally typed cones in the central retina of human observers using adaptive optics. Using chromatic adapting fields to modulate the relative steady-state activity of long (L)- and middle (M)-wavelength-sensitive cones, we found that single-cone detection thresholds varied predictably with the spectral demographics of the surrounding cones. The spatial scale and spectral pattern of these photoreceptor interactions were consistent with lateral inhibition mediated by retinal horizontal cells that receive nonselective input from L and M cones. These results demonstrate a clear link between the neural architecture of the visual system inputs—cone photoreceptors—and visual perception and have implications for the neural locus of the cone-specific circuitry supporting color vision.

Published: September 2017

El propósito del estudio fue comparar los componentes antropométricos y de aptitud física en practicantes de parkour y analizar qué influencia tienen los años de entrenamiento sobre estas variables. Metodología: Se contó con la participación de 18 personas de género masculino, divididas en tres grupos según los años de entrenamiento. Se midieron las variables antropométricas: talla, peso, masa músculo esquelética, masa grasa e índice de masa corporal, y las variables de aptitud física: flexibilidad (extensibilidad isquiosural), potencia en miembros superiores e inferiores y resistencia a la fuerza explosiva. Se utilizó una ANOVA de una vía de grupos independientes y el test de normalidad post hoc Tukey para determinar diferencias significativas, a un nivel alfa de p < .05. Resultados: no se encontró diferencias significativas entre los grupos en ninguna de las variables antropométricas, pero sí existieron diferencias significativas en los componentes de aptitud física, salto horizontal a pies juntos (p = .02), SCMES (p = .01) y SCM (p = .00). El grupo con más años de entrenamiento mostró mejores resultados que los otros dos grupos. Conclusiones: los resultados obtenidos mostraron que la composición corporal en los atletas de parkour no estuvo influenciada por años de práctica; sin embargo, las diferencias encontradas en las variables de la aptitud física y la cantidad de años de práctica parecieran provocar efectos en el rendimiento, sobre todo en la potencia física del tren inferior y superior.

The aim of this research is to analyze the acceptance of the Information and Communications Technology as tools to support the practice of teaching in private universities in Guatemala. It is a quantitative, descriptive, and transversal research study. It has been carried out with professors of degree and postgraduate courses in presential mode and with virtual environments of learning. A questionnaire was used to measure the “technology acceptance” (dimension) from three sub-dimensions: knowledge, attitude, and practicality. To analyze the data collected, we used descriptive statistics. The results were interpreted based on the “Technology Acceptance Model” (Davis, 1989; Venkatesh et al., 2003; Venkatesh y Bala, 2008). It was found that teachers are convinced of the usefulness of ICT, due to the variety of resources provided to develop school practices, tailored to the training needs and the needs arising from the knowledge society. However, professors “rarely” supervise the correct use of these tools by the student and “never” seek expert advice on the subject.

Maximizando y minimizando la función aS1adS2adonde S1 y S2 son las matrices de covarianzas muéstrales de dos poblaciones p-variantes, con vectores de medias iguales o diferentes, se consiguen dos combinaciones lineales de las componentes del vector p-variante. Si los dos grupos tienen estructuras de dispersiones diferentes, esas combinaciones son usadas para la clasificación de individuos que proceden de una de dos poblaciones normales multivariantes. Este método comparado con el método de clasificación usando el cociente de verosimilitudes (Mardia, 1976), para poblaciones normales simuladas por Monte Carlo con p=2, p=3 y p=4, resultan equivalentes.

Una parte importante de la utilidad del análisis de influencia es determinar la debilidad de algunos estimadores tradicionales frente a la presencia de datos discordantes tales como los Bj (coeficientesde regresión) y los ri (residuales) en un análisis de regresión; la X (media muestral) en un análisis inferencíal, etc. los cuales han sido desarrollados ampliamente. Pero como muy poco se ha difundido sobre la correlación parcial, tratamos de presentar los efectos que se producen en dichos estimadores ante la presencia de datos discordantes o influyentes con una aplicación a un conjunto de datos socio-económicos del Perú.

Published: September 2017

It has been suggested that hepatobiliary carcinomas are less frequent in Wilson’s disease (WD) than in liver diseases of other etiology. However, the protective role of copper against malignancies is debated. Only a few cases of cholangiocarcinoma (CCC) in WD have been published. Here we report on a case of a 47-year-old male H1069Q homozygous, Kayser-Fleischer ring positive WD patient with a low ceruloplasmin level who was followed up and treated with chelating agents throughout nine years. The patient presented with neurological symptoms and liver cirrhosis at diagnosis. Clinical symptoms regressed after the treatment initiation. Rapidly developed tumour metastases were found in the bones, lung and liver (without jaundice). Autopsy revealed cholangiocarcinoma as the primary tumour confirmed by strong CK7 positivity and glypican-3 negativity. The curiosity of the presented case is the very rapid development of CCC despite continuous chelating agent therapy.Abbreviations: CCC: cholangiocarcinoma; HCC: hepatocellular carcinoma; WD: Wilson disease.

Published: September 2017

Background & Aims: Recent reports suggest an involvement of Th17 responses in inflammatory and autoimmune reactions in alcoholic liver disease (ALD). Our study aimed to assess serum levels of Th17-interleukins in ALD with regard to the frequency of liver-specific autoantibodies and degree of liver damage.Methods: Ninety-five patients with ALD were enrolled. Serum concentrations of IL-17F, IL-17A, IL-22 were assessed by ELISA. The presence of autoantibodies AMA-M2, SLA/LP, LKM-1, LC1, anti-F-actin, anti-desmin and anti-myosin in serum was assessed by immunoblotting, ANA antibodies were detected by ELISA. The results were analysed with regard to the degree of hepatic damage.Results: Serum IL-17F was significantly elevated in ALD patients compared to controls (p=0.03). There was a correlation between serum IL-17F and degree of liver failure evaluated by the MELD score (rs=0.23, p=0.03). Serum IL-22 also correlated with MELD score (rs=0.32, p=0.007) and CTP score (rs=0.28, p=0.02). Anti-F-actin antibodies were present in 19% and ANA-antibodies in 11% of the patients in the study group, and in no subjects in the control group. The prevalence of anti-F-actin autoantibodies was higher in subjects with more advanced liver diseases but also independently associated with IL-17A in the regression analysis. Furthermore, serum IL-22 in anti-F-actin(+)-patients was significantly higher compared to anti-F-actin(-)-patients (p=0.03).Conclusions: Elevation of serum IL-17A, IL-17F, IL-22 correlated with the progression of liver damage and also with presence of F-actin in ALD. Alcoholic liver disease may trigger autoimmunity and formation of autoantibodies, especially anti-F-actin, with possible engagement of Th17-related cytokines in this process.Abbreviations: AA: acetaldehyde; Abs: antibodies; AFP: α-fetoprotein; ALD: alcoholic liver disease; ALT: alanine aminotransferase; AMA-M2: antimitochondrial antibodies; ANA: antinuclear antibodies; ASMA: anti-smooth muscle antibodies; α-SMA: alpha smooth muscle actin; CTP Score: Child-Turcotte-Pugh Score; GAHS: Glasgow Alcoholic Hepatitis Score; GGT: γ-glutamyl transpeptidase; HBV: hepatitis B virus; HCV: hepatitis C virus; HIV: human immunodeficiency virus; HSCs: hepatic stellate cells; IL-β1: interleukin β1; IL-6: interleukin 6; IL-17A: interleukin 17A; IL-17F: interleukin 17F; IL-22: interleukin 22; KCs: Kupffer cells; LC1: liver cytosol antigen type 1; LKM-1: liver kidney microsomal antigen; MA: malondialdehyde; MELD: Model of End-Stage Liver Disease; NASH: non-alcoholic steatoheptatitis; SLA/LP: soluble liver antigen/liver-pancreas; TGF-β: tumour growth factor β; TNF-α: tumour necrosis factor α.

Abstract: The basic legal conditions for pursuing medical activities in Hungary require that psychologists be employed at certain somatic departments. In the Hungarian medical practice, however, attitudes recognizing the potential role of psychological factors in the course of diseases are not widely present. The modern psychosomatic approach to healing includes biological, psychological and social factors that may predispose one to, precipitate or perpetuate a medical condition. This case study of a 35-year-old woman reports on a therapy in which the symptoms were indicative of both premature ovarian failure and anxiety, influencing each other in a bidirectional way. Therapy also included interventions on physical (hormonal therapy, Jacobson’s progressive relaxation technique) and psychological levels (cognitive behavioral interventions). This case management is an example for how physician-psychologist collaboration serves the best interests of patients. Orv Hetil. 2017; 158(36): 1432–1435.
