Spatial variation in allometric growth of invasive lionfish has management implications
Authors: Villaseñor-Derbez Juan Carlos
Published: April 2019

Lionfish (Pterois volitans/miles) are an invasive species in the Western Atlantic and the Caribbean. Improving management of invasive lionfish populations requires accurate total biomass estimates, which depend on accurate estimates of allometric growth; sedentary species like lionfish often exhibit high levels of spatial variation in life history characteristics. We reviewed 17 published length-weight relationships for lionfish taken throughout their invasive range and found regional differences that led to significant misestimates when calculating weight from length observations. The spatial pattern we observed is consistent with findings from other studies focused on genetics or length-at-age. Here, the use of ex situ parameter values resulted in total biomass estimates between 76.2% and 140% of true observed biomass, and up to a threefold under- or overestimation of total weight for an individual organism. These findings can have implications for management in terms of predicting effects on local ecosystems, evaluating the effectiveness of removal programs, or estimating biomass available for harvest.

Published: April 2019

The aim of the study was to investigate the sensitivity of planktonic and film forms of C. albicans and C. glabrata to cationic surfactant antiseptics. Materials and methods. The study was based on investigating 20 clinical strains of C. albicans and 15 C. glabrata isolated from surgical inpatientsю. The sensitivity of planktonic forms of investigated strains to antiseptic agents was quantitatively evaluated by two-fold serial dilutions (macrodilution) in Sabouraud liquid nutrient medium. Biofilm-forming properties of clinical strains C. albicans and C. glabrata were assessed by using the Christensen’s spectrophotometric method (MtP-test “microtiter plate test”). The influence of the antiseptics on C. albicans and C. glabrata film forms was assessed by the reproduction of the biofilms according to the above-described procedure with adding antiseptics in sub-bacteriostatic concentrations and the subsequent spectrophotometric ODU assessment. In the study we used antiseptics based on cationic surfactants, chlorhexidine digluconate 0.05 (Chlorhexidine-KR, manufactured by PJSC “Khimfarmzavod “Chervona zirka"”, Kharkiv, Ukraine (CHH)) and decamethoxin 0.2 (Decasan, produced by Yuria-Farm LLC ", Kyiv, Ukraine (DCM)). Results. According to the research results, lower sensitivity of C. glabrata strains to CHH was found, compared to the sensitivity of C. albicans strains. In addition, the activity of DCM in the investigated representatives of Candida spp. did not differ significantly. Clinical strains of C. glabrata were more susceptible to DCM compared to their susceptibility to CHH. C. albicans strains showed medium film-forming properties, while C. glabrata - high. The investigated cationic surfactant antiseptics possessed the same degree of activity on the film-forming properties of clinical strains of Candida spp. Conclusions. Cationic surfactant antiseptics (CHH and DCM) possess antifungal activity against planktonic and film forms of C. albicans and C. glabrata.

Published: April 2019

The effect of aflatoxin on reproductive health takes a systematic approach as it indicates that a significant number of people living in the third world regions are exposed to these toxins due to the poor storage of grains. To expose the effects of aflatoxin M1 a hydroxylated metabolite of aflatoxin M1 Twenty four Adult male Wister rats were acclimatized and broken down into four groups, Test Group one (Two weeks exposure), Group Two ( four weeks exposure), Group Three ( Six weeks exposure) and Group Four ( Control Group). The Test Group 1, 2 and 3 were orally administered 7.2g/kg (LD50) of Aflatoxin M1 for the desired weeks of exposure and the sperm cell quality was assessed to determine the effect of Aflatoxin M1 on sperm cell quality in Adult male wister rat. The predetermined level of sperm cell quality is its ability to be motile as the motility of the sperm cell determines its viability. Group three had the highest presence of sluggishly immotile cells with very low progressive motility, followed by group, two and one, 37.5+ 9.97, 55.00+9.91, and 71.67+3.07 as against the control groups 85.8+2.17 with the highest significance at the group three which showed an extended exposure of aflatoxin m1 (p=0.05). This study links infertility and aflatoxin consumption, as the higher the doses the more spermatotoxicity is built which invariably could lead to sterility and azoospermia.

Authors: Santos Kaue , Pires Ricardo
Published: April 2019

Este artigo aborda o estudo e aplicação do classificador do tipo Máquina de Vetores de Suporte (SVM) na diferenciação entre crises epilépticas e crises não epilépticas psicogênicas (CNEP). Um banco de dados com exames de eletroencefalograma (EEG) contendo 117 crises epilépticas e 42 crises não epilépticas psicogênicas foram coletados na Unidade de Videoeletroencefalografia do Instituto de Psiquiatria do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (IPq-HCFMUSP). Baseando-se nos registros dos 18 canais do EEG durante cada crise, foram gerados vetores de características com quatro atributos: média, desvio padrão, valor máximo e valor mínimo. Estes vetores de características foram utilizados na fase de treinamento e avaliação do classificador SVM em quatro configurações de kernels disponíveis: Linear, Polinomial, Função de Base Radial (RBF) e Sigmoide. Como resultado, o kernel Polinomial apresentou melhor desempenho com a taxa de acerto (acurácia) de 78,7%, sensibilidade de 100% e especificidade de 2,4%. Com base nos vetores de características utilizados, foi possível concluir que o classificador SVM é adequado para a detecção de crises epilépticas, sendo inadequado para os casos de CNEP. Estes resultados podem ser otimizados com a aplicação da Transformada de Fourier ou Transformada Wavelet no tratamento prévio dos sinais de EEG, além da geração de vetores de características com atributos distintos.

Analysis of Heavy Metal Pollution Based on Two-Dimensional Diffusion Model
Authors: Zeng Yunhui , Li Wenhao , Guo Hongfei , Chen Yilin , Jiang Xiaoqing , Yu Bingjie
Published: April 2019

This paper takes the propagation characteristics of heavy metals and the judgment of the location of pollution sources as the research objects, aiming to analyze the propagation characteristics of different heavy metals. Firstly, the Gaussian diffusion model is conducted to establish the propagation characteristics model of heavy metal pollutants in the atmosphere. Then, based on the law of conservation of mass and the law of two-dimensional diffusion, the two-dimensional diffusion model is adopted to establish the propagation characteristics model of heavy metals in soil moisture. According to these two models, the nonlinear differential equations are established respectively, revealing that the characteristics of the two propagation ways are related to space, time, diffusion coefficients, and other factors. Then, in the light of the propagation characteristics of different heavy metals, the least square method is applied to reduce the data calculation error and obtain the specific location of the pollution source. Finally, through establishing the three-dimensional diffusion model of heavy metal diffusion by introducing artificial control, speed and angle of prevailing wind direction, and other factors, the model is further optimized. The establishment of this model provides an important theoretical basis and guiding significance for the future study of heavy metal pollutants.

Effect of Fe, Ni and Cr on the corrosion behaviour of hypereutectic Al-Si automotive alloy in 3.5% NaCl solution at different temperature and velocity
Authors: Kaiser M. S. , Sabbir S. H. , Rahman M. , Kabir M. S. , Nur M. Al
Published: April 2019

The main focus of this study is to examine and evaluate the effect of Fe, Ni and Cr on the corrosion behaviour of hypereutectic Al-Si automotive alloy in 3.5% NaCl solution. Experimental information are attained using conventional gravimetric measurements under different solution temperature and velocity and complemented by resistivity, optical micrograph, scanning electron microscopy (SEM) and X-ray analyzer (EDX) investigations. All the alloys show the negative corrosion rate due to formation of a very thin film of aluminum oxide and hydroxid on the surface. Intermetallic particles in the alloys play a major role in passivity.

Temperature accelerates the corrosion and the higher velocity breakdown of the passive film. It also affects the resistivity of the alloys. The results from this study also indicate that the temperature and velocity increase the negative corrosion rate of the alloys due to higher rate of chemical reactions. SEM and EDX analysis indicate that the surfaces compose with a thin layer of aluminum oxide and hydroxide corrosion products.
Hot-melt extrusion and prilling as contemporary and promising techniques in the solvent free production of solid oral dosage forms, based on solid dispersions
Authors: Aleksovski Aleksandar , Vervaet Chris , Dreu Rok
Published: April 2019

Hot melt extrusion and prilling are gaining importance as solvent free and continuous techniques in the production of solid oral dosage forms with added value, by incorporating active compound in a molten carrier which is further solidified to form solid dispersion. This article reviews these two techniques in terms of understanding process basics, equipment characteristics, required properties of processed
materials and application of the processes for development of solid oral dosage forms. Studies revealed that both hot-melt extrusion and prilling are regarded as simple, robust and continuous methods for processing different types of materials and production of solid dosage forms based on solid matrices. However, understanding of their concepts and requirements together with careful material selection is crucial for stable material processing and obtaining stable products of high-quality. Hot-melt extrusion proved to be a suitable method for production of modified release dosage forms, taste masked dosage forms and dosage forms offering improved drug dissolution rate and solubility. Prilling till now has been successfully applied just in the production of multiple unit drug delivery systems for immediate and sustained drug delivery. Further studies on product development and process understanding are required for full implementation of prilling in the pharmaceutical field.

Authors: Yves Oscar Nganso Ditchou , Ngoung GA Amang A , Desire Soh , Fredy Brice Simo Nemg , Barthelemy Nyasse
Published: April 2019

This paper aimed at studying the antioxidant efficacy of the methanolic leaf extract of Clerodendrum splendens, a plant of the Lamiaceae family. Phytochemical tests carried out on extracts of Clerodendrum splendens leaves have been able to detect the presence of secondary metabolites such as Flavonoids, Tannins, Saponins and Terpenoids. The results of the antioxidant activity have shown that CSF2, CSF3 fractions and CSB, CSG fractions similarly inhibited hepatic lipids but significantly less than vitamin C. Compared to all fractions, the CSB fraction shows the best inhibitor on the peroxidation of hepatic lipids because at 150 μg/mL, there is a maximum activity (2.5 μg/mL of protein). However, it is found that CSF3, CSF2 and CSG have higher IC50 values than vitamin C (5.613±0.117) while CSEB, CSB and CSC fractions showed lower IC50 values than vitamin C, which is used as the reference reducing compound. The lower the IC50 value compared to vitamin C, the greater the antioxidant capacity of the plant extract. The results of this study suggest that Clerodendrum splendens represents an untapped source of compounds with potential antioxidant activity that could be explored in the development of new therapeutic natural products.

Además, se analizaron las características psicométricas del COPE abreviado de Carver (1997). Participaron 216 personas asistentes a unas Jornadas de Duelo, el 81% (175) mujeres, de edad media 49 años (DT=14,59). Se midieron estilos de afrontamiento (cuestionario COPE abreviado de Carver, 1997) y capacidad de afrontamiento de la muerte (AM) (escala de afrontamiento de la muerte; Bugen, 1981). Se realizaron análisis factoriales exploratorios en ambos cuestionarios, análisis de diferencias de medias y correlaciones. Para el cuestionario COPE se ajustó un modelo de nueve factores de primer orden y dos de segundo orden; afrontamiento activo (AA) y evitativo (AE). Las mujeres obtuvieron medias significativamente más altas en AE (1,65 vs 1,47) y menores en AM (48,42 vs 54,05). En mujeres se obtuvo asociación directa entre AM y AA (r=,241) y entre AA y AE (r=,284). Ambos sexos asociación directa entre AM y Aceptación (r=,561 y r=,378; p<,001). Los hombres, correlación inversa (r=-,536; p<,001) entre AE y Aceptación. Se valida una estructura de la escala COPE abreviada para población española. Se observa que las mujeres utilizan un mayor repertorio de estrategias de afrontamiento y que, en ellas, no está reñido el uso combinado de ambos estilos de afrontamiento, activo y evitativo, sin embargo, en hombres, el uso del estilo evitativo parece impedir estrategias activas como la aceptación.

¿La Psicología Humanista como Pseudociencia?
Authors: Gimeno-Bayón Ana , Rosal Ramón
Published: April 2019

A la vista de la aparición del término “pseudociencias” en los medios de comunicación, en relación con algunos métodos y modelos de intervención en psicoterapia, el presente artículo pretende dar cuenta de algunos criterios a la hora de entender la calidad científica en este ámbito. Igualmente quiere abogar por la coexistencia de un pluralismo de modelos, cuya diversidad –lejos de una rigidez uniformadora y dogmatizante en favor de uno solo de ellos- comporta una riqueza de paradigmas psicológicos y psicoterapéuticos. La posibilidad de convivencia de éstos, en un momento dado, favorece un diálogo que hace progresar el conocimiento, sin restar credibilidad en cuando a la calidad científica de los mismos. En el artículo también se aborda la diferencia existente entre lo que se entiende por evidencia científica en las ciencias naturales –como, por ejemplo, en Biología o Medicina- y en las ciencias humanas (o sociales) como es el caso de la Psicología y la psicoterapia. En cuanto a esta última, se citan algunos de los resultados y conclusiones a los que se ha llegado, y las propuestas acerca de nuevos paradigmas de investigación que se apuntan en este campo.
Investigation of the Trailing Edge Modification Effect on Compressor Blade Aerodynamics Using SST k-ω Turbulence Model

Published: April 2019

A gas turbine power plant in Thailand had the problem of compressor blade fracture in Stages 6–8, which was caused by housing damage. This gas turbine has a total of 15 stages. The housing damage reduced the lifetime of blades to an unacceptable level. This article shall report the solution and outcomes. Three-dimensional (3D) compressor blade models in the problematic stages were prepared by a 3D scanning machine to find a solution based on computational fluid dynamics (CFD), and then were completed for simulation by adding Stages 5 and 9 to become a multi-stage axial model. The latter models were modified by trimming the trailing edge by 1-, 5-, and 10-mm. Using ANSYS CFX R19.2 software, the CFD results of the trailing edge modification effect on flow using the shear stress transport (SST) k-ω turbulence model revealed aerodynamics inside the problematic stages both before and after blade modifications. Modifying the blade by 5 mm was suitable, because it had lesser effects on aerodynamic parameters: pressure ratio, drag, and lift coefficients, when compared to the modification of 10 mm. The larger the modification, the greater the effect on aerodynamics. The effects on aerodynamics were intensified when they were modified by 10 mm. The validation of base line blades was conducted for the overall compressor parameters that were compared with the measurable data. These results were accepted and gave positive feedbacks from engineers who practically applied our reports in a real maintenance period of gas turbine.

Faba bean seeds are regarded as a highly valuable protein source for human and animal nutrition. High yield and quality of faba bean require adequate mineral nutrition. The aim of the study was to assess the impact of potassium (K) and elemental sulfur (S) on crude protein (CP) and tannin content (TC) in seeds, crude protein yield (CPY), and amino acid (AA) composition. Field trials were carried out during 2010–2013 in the temperate climate of Central Europe. The study assessed the influence of the following factors: variable soil K content and fertilization (K1, K2, K3, and K4) and elemental S application (0, 25, and 50 kg S ha−1). Plants were harvested at two growth stages to obtain immature seeds and mature seeds. K and S applications did not have a significant impact on CP and AA composition, including sulfur AA content. The TC decreased in response to increasing content of plant-available K in soil. In respect to CPY, the results indicate a positive response of faba bean to increasing K content in soil. The effect of S fertilization depended on the K treatment. The most beneficial influence of S on CPY was registered on K-poor soil.

Summer transhumance to alpine pastures (ALP) is widespread in dairy systems of alpine regions. This study aimed to investigate the effects of transhumance of Brown Swiss cows to ALP on the yield, composition, and coagulation properties of milk (MCP), and on cheese yield (CY). The study involved 12 multiparous cows kept at a mountain lowland permanent farm (PF), which were divided into two equal groups: One remained at the PF, the other was moved to the ALP (1860 m above sea level) from July to September. Every month (June to October), daily milk yield (MY) and body condition score (BCS) were recorded, and individual milk samples (n = 60, 2000 mL each) were collected to assess milk composition, MCP, and CY. Compared with PF, ALP cows had a reduced MY and BCS, which was maintained on return to the PF, greater fat and lower protein contents of milk. Neither MCP nor CY were affected by summer transhumance. In conclusion, summer transhumance did not affect the cheese making efficiency of milk but depressed MY and consequently daily cheese yield, which was nearly 2 kg/d lower for the ALP than the PF cows and was only partially recovered after returning to the PF in autumn.

Published: April 2019

Increasingly, intensive livestock production systems have increased societal concern regarding the current animal welfare standards. We investigated whether individuals in their roles as consumers and citizens believe that the current European regulations regarding animal welfare should be more restrictive. Factors affecting this decision were assessed by analyzing respondents’ understanding of animal welfare-related issues, their subjective and objective knowledge levels, the credibility they assign to different information sources, their perceptions toward the current restrictiveness of animal welfare standards, and their socioeconomic characteristics. Data were collected using a semi-structured questionnaire distributed in eight European Union (EU) countries (Spain, the United Kingdom, Poland, Greece, Lithuania, Romania, Italy, and Sweden) with 3860 total responses. The results showed that consumers are more reluctant to adopt more restrictive regulations than respondents in the role of citizens. Respondents from northern European countries (Poland and Sweden) are more likely to support regulations that are more restrictive than the current minimum requirements than respondents from southern countries (Spain and Italy). Women were found to be more concerned with the welfare of pigs and laying hens—lending credibility to the Internet as an information source—and were more likely to support more restrictive animal welfare legislation.

Published: April 2019

Using a community sample of 1205 elderly persons, we investigated the associations and potential interactions between Apolipoprotein E (APOE) genotype and serum phosphatidylethanolamine (PlsEtn) on cognition and dementia. For each person, APOE genotype, PlsEtn Biosynthesis value (PBV, the combination of three key PlsEtn species), cognition (the combination of five specific cognitive domains), and diagnosis of dementia was determined. APOE genotype and PBV were observed to be non-interacting (p > 0.05) and independently associated with cognition: APOE (relative to ε3ε3:ε2ε3 (Coef = 0.14, p = 4.2 × 10−2); ε3ε4/ε4ε4 (Coef = −0.22, p = 6.2 × 10−5); PBV (Coef = 0.12, p = 1.7 × 10−7) and dementia: APOE (relative to ε3ε3:ε2ε3 (Odds Ratio OR = 0.44, p = 3.0 × 10−2); ε3ε4/ε4ε4 (OR = 2.1, p = 2.2 × 10−4)); PBV (OR = 0.61, p = 3.3 × 10−6). Associations are expressed per standard deviation (SD) and adjusted for serum lipids and demographics. Due to the independent and non-interacting nature of the APOE and PBV associations, the prevalence of dementia in APOE ε3ε4/ε4ε4 persons with high PBV values (>1 SD from mean) was observed to be the same as APOE ε3ε3 persons (14.3% versus 14.0%). Similarly, the prevalence of dementia in APOE ε3ε3 persons with high PBV values was only 5.7% versus 6.7% for APOE ε2ε3 persons. The results of these analyses indicate that the net effect of APOE genotype on cognition and the prevalence of dementia is dependent upon the plasmalogen status of the person.
