Published: January 2019

Abstract
Entomopathogenic nematode species perform differently under different environmental conditions; therefore, the authors investigated the biological and environmental characteristics that could optimize performance of Steinernema innovationi. The authors studied the effect of temperature on infectivity and reproduction, the foraging behavior and host range. Thermal activity was optimal between 22 and 25°C. Highest infective juvenile (IJ) yields in last instar Galleria mellonella were observed at 22°C (333,014 IJs/g) and 25°C (354,165 IJs/g). An average of 26% of the IJs infected G. mellonella larvae at depths of 15 cm within 24 hr. Steinernema innovationi IJs raised greater than 95% of their body off the substrate and moved in a circular pattern, but did not jump. The hosts, Acheta domesticus, Chilo partellus, and Plutella xylostella showed the least susceptibility. All other hosts, [Eldana saccharina, Sesamia calamistis, Tenebrio molitor, G. mellonella, Cydia pomonella] suffered 100% larval mortality. Pupal mortality ranged from 47 to 68%. An LC50 and LC70 of 3 and 31 IJs/larva, respectively, were calculated for Agrotis ipsilon. The results indicate that S. innovationi is adapted to moderate temperatures. Furthermore, to the author’s knowledge this is the first report of a nematode (particularly from ‘glaseri group’) that shows cruiser-type behavior in movement, but also nictates.

Published: January 2019

Abstract
The objective of this study is to define a consumption indicator (CI) for water that can be used as a reference for developing water conservation plans at public schools. The methodology followed consists of a historical water consumption data survey of all schools in Recife, Brazil, a registration survey of school buildings, the calculation of consumption indicators for the period 2012–2015, and finally, the calculation of reference indicators. The results obtained indicated a reference range for the CI of 13.0 ± 2.0 L/student/day for water considering the set of all school typologies, with a 95% confidence level. The analysis of the schools in groups, classified into four typologies, led to the following reference ranges: 11.5 ± 2.0 L/student/day for regular schools, 13.5 ± 3.5 L/student/day for extended period schools, 22.0 ± 6.0 L/student/day for full period schools, and 18.5 ± 6.5 L/student/day for technical schools. Through the use of a consumption indicator, schools with a limited supply of potable or above average water can be identified and specific actions can be developed to achieve a sustainable use of water in the school environment.

Introduction:Since spices are taken as ready-to-eat products, they are not subjected to heat treatment. The use of spices contaminated with pathogens can lead to morbidity and mortality.Materials and Methods:The study was conducted on 162 samples of 25 spices collected from retail and production sites in different regions of Ethiopia between January 2010 to December 2017 to determine the concentrations of heterotrophic plate count andStaphylococcus aureusby pour plate method; for coliforms using NMKL Method No. 44; for mould and yeast enumeration using spread method and forSalmonellausing ES ISO 6579. The data was analysed using SPSS version 20.0.Results:Moulds, yeasts, total coliforms, heterotrophic plate count, total coliforms, thermotolerant coliforms,E. coliandS. aureusabove the acceptable limits were observed in 5 (3%), 7 (4.3%), 2 (1.2%), 20 (12.3%), 10 (6.2%), 9 (5.6%) and 19 (11.7%) samples respectively.Salmonellaspecies was notnoticed in any of the samples tested. No bacterial and fungal contaminations were observed in 11 of 25 spices.Conclusions:Few spices samples had 1.2 to 12.3% of the microbiological indicators, spoilages or pathogens exceeded the ICMFS guidelines. The use of these contaminated spices may pose risk to human health.
Una mirada crítica de la formación del profesional de enfermería con perspectiva reflexiva
Authors: Camacho Franco Eduardo Ricardo , Rodríguez Jiménez Sofía 
Published: January 2019

Introducción: Este trabajo aborda el contexto de la enseñanza clínica, vista como una entidad compleja, desde los conceptos de Vygotsky cobran sentido, sobre todo en: la zona de desarrollo próximo, componente del aprendizaje social y es ahí donde se identifican los discursos docentes y profesionales en los entornos de aprendizaje clínico. Desarrollo: Se analiza la importancia que tiene la teoría del Prácticum Reflexivo para la formación de enfermeras, desde las aportaciones de D. Schön, y el papel de la tutoría clínica como propuesta en los procesos de formación profesional. En la actualidad los modelos de enseñanza que predominan en las instituciones educativas, se encuentran en una discrepancia entre el discurso en las aulas, los planes de estudio y la realidad de la práctica clínica en donde prevalece una ideología caracterizada por la racionalidad técnica. Conclusiones: A través del tiempo se han llevado a cabo diversas metodologías en la enseñanza de enfermería, así también se han hecho análisis y críticas de las mismas, las cuales han permitido ciertas transformaciones en la formación profesional, sin embargo en el campo de lo ideológico, político, filosófico se ha estancado y por ende no se accede a otros paradigmas educativos.

Introducción: El incremento del número de personas poseedoras de un estoma, trae consigo la necesidad de contar con personal capacitado para proporcionarle los elementos necesarios para su reintegración a la vida social, familiar y laboral. Objetivo: Analizar el efecto que tiene la intervención educativa de enfermería para la rehabilitación de personas con una ostomia. Metodología: Se trata de un estudio de tipo cuasi-experimental, la muestra se constituyo de 110 personas ostomizadas de cuatro hospitales a las que se les aplicó un instrumento que fue validado por expertos en el área. Para el análisis de datos se utilizó estadística descriptiva e inferencial por medio de la X2. Resultados: En los resultados se observa diferencia estadísticamente significativa entre la intervención educativa y la rehabilitación laboral (p=0.000), también se observo diferencia estadísticamente significativa entre la intervención educativa y la rehabilitación social y familiar (p=0.000). Discusión: Coincidiendo con Montovani en donde afirma que la falta de información, educación y comunicación son la causa para que el paciente no pueda participar activamente en su autocuidado. De acuerdo con Boccardo se establece que la mayoría de los pacientes ostomizados no retornan totalmente al trabajo pero si parcialmente a sus actividades siendo ésta la parte más difícil de superar. Conclusiones: Se sustenta que la intervención educativa en personas ostomizadas planificada, estandarizada y evaluada, es fundamental para lograr su rehabilitación educativa, laboral, social y familiar.

La cabrilla pinta, Epinephelus labriformis, es una especie de la familia Serranidae, explotada comercialmente en la Bahía de Navidad, Jalisco, México. El objetivo del trabajo fue describir las características reproductivas de E. labriformis. Se realizaron muestreos mensuales entre 1998 y 2008 utilizando redes agalleras. De cada organismo se obtuvo la longitud total (LT) y el peso total (PT); las gónadas fueron extraídas, pesadas, clasificadas según el estadio de desarrollo y preservadas para análisis histológicos. Se recolectaron 940 ejemplares, 521 fueron hembras y 419 machos. La longitud promedio de las hembras fue de 30,1 (± 0,14) cm y la de los machos 31,3 (± 0,13) cm LT. Los máximos valores del índice gonadosomático y los mayores porcentajes de gónadas maduras tanto en hembras como en machos, se presentaron en abril y agosto. El factor de condición presentó escasa variación temporal. Mediante el análisis histológico de las gónadas se identificaron ejemplares en transición, con ovarios con ovocitos en regresión y tejido testicular en desarrollo. El desarrollo de los ovocitos es asincrónico y el del testículo es de tipo lobular. El ejemplar más pequeño encontrado en transición midió 25,6 cm LT. La longitud promedio de maduración sexual fue 29,6 cm LT para hembras y 31,3 cm LT para machos; contrastando estas tallas con las de captura, se infiere que los individuos capturados habrían tenido al menos un evento reproductivo. E. labriformis es un hermafrodita protógino que presenta una mayor actividad reproductiva en primavera-verano lo cual lo vuelve altamente vulnerable al impacto de la pesca.

Abstract
The main purpose of this study was to isolate airborne fungi and assess seasonal variations in air contamination with their particulates by determining the levels of their propagules in the nave and exonarthex of a church. We also monitored indoor microclimate as a determining factor for fungal proliferation on wall paintings, spore release, and transmission through the air. The temperature and relative humidity of the nave favoured fungal growth. A total of 33 fungi were isolated, mainly of the phylum Ascomycota, and to the lesser extent of the phyla Zygomycota and Basidiomycota. The most common were the fungi of the genera Penicillium and Aspergillus (23.55 % and 20.58 %, respectively). Sørensen’s quotient of similarity (0.37) suggests moderate species overlap and constant exchange of fungal propagules between the nave and exonarthex. The autumn had the highest diversity, with 17 documented taxa, followed by the summer and the winter. The spring had only eight taxa. Quantitative analysis of the airborne mycobiota in the nave (430±84.85 to 1880±106.07 CFU m-3) and exonarthex (715±59.62 to 2295±91.92 CFU m-3) showed very high contamination throughout the year, with values exceeding the maximum permissible concentrations by most standards. Many of the fungi determined in this study are known for their biodeteriogenic, toxigenic, and allergenic properties, and are a threat not only to occasional visitors and staff, but also to valuable works of art decorating nave walls.
Extracting parasite effects of electrical bioimpedance measurements
Authors: Dutra Douglas , Bertemes-Filho Pedro 
Published: January 2019

Abstract
The objective of this work is to develop a technique for filtering parasitic effects from the impedance spectra (IS) measured in biological material phantoms. IS data are contaminated with unexpected capacitive and inductive effects from cable, input/output amplifiers capacitances, electrode polarization, temperature and contact pressure when collecting data. It is proposed a model which contains an RLC-network in series with the Cole model (RSC), then called RLC-Cole. It was built four circuits composed by resistors, capacitors and inductors. An impedance analyzer (HF2IS) was used to perform the measurements in the frequency range of 1 to 3000 kHz. Data were fitted into the model and comparisons to the nominal values were made. In order to validate the proposed model, a gelatin phantom and a chicken breast muscle impedance spectra were also collected and analyzed. After filtering, Cole fitting was performed. Results showed a maximum root-mean-square error of 1% for the circuits, 2.63% for the gelatin phantom, whereas 2.01% for the chicken breast. The RLC-Cole model could significantly remove parasitic effects out of a tissue impedance spectrum measured by a 4-point electrode probe. This may be highly important in EIS systems whose objective is to discriminate a normal tissue from a cancerous one.
Rectifying memristor bridge circuit realized with human skin
Authors: Pabst Oliver 
Published: January 2019

Abstract
It has been demonstrated before that human skin can be modeled as a memristor (memory resistor). Here we realize a memristor bridge by applying two voltages of opposite signs at two different skin sites. By this setup it is possible to use human skin as a frequency doubler and half-wave rectifier which is an application of the non-linear electrical properties of human skin. The corresponding electrical measurements are non-linear since these are affected by the applied stimulus itself.
Temperature dependence of the energy band gap of CuSi2P3 semiconductor using PSOPW method

Published: January 2019

Abstract
Theoretical formalism based on the orthogonalized plane wave method supplemented by a potential scaling scheme was used to predict the temperature dependence of energy gap of CuSi2P3 semiconductor. A computer code in Pascal was used to perform the variation of fundamental energy gap with temperature in the range of 150 K to 800 K. The dependence of energy gap on temperature for lattice dilation contribution, lattice vibration contribution and total temperature effect were performed separately. The results revealed that, as temperature increases, the top of the valence band and the bottom of the conduction band increase, while the energy band gap decreases. Generally, at low temperatures, the energy gap varies slowly and exhibits a nonlinear dependence and approaches linearity as temperature increases. The calculated energy gap of CuSi2P3 at T = 300 K is 0.4155 eV. The temperature coefficients in the linear region due to lattice dilation contribution, lattice vibration contribution and total temperature effect were calculated as –1.101 × 10−5 eV/K, –1.637 × 10−4 eV/K and –1.7523 × 10−4 eV/K, respectively. Also, the ratio of temperature coefficient of the energy gap due to LV contribution to its value and LD contribution in the linear region is equal to 14.868. That ratio is compared to those of CuGe2P3 and III-V compounds, where those of the latter show a systematic change with Eg. Moreover, the Eg of all the compounds shows a quadratic dependence on the inverse of mean bond length.

Authors: El-Fadl A. Abu , Abdel-Salam A.M. , Nashaat A.M. 
Published: January 2019

Abstract
Single crystal of glycine hydroflruoride (GHF) was grown from aqueous solution by slow evaporation technique. The structure of the grown crystal was tested and analyzed through X-ray powder diffraction. The functional groups have been identified from the FT-IR spectra. Slabs cut normal to the b-axis from the grown crystal were subjected to incident radiation with a wavelength range of 200 nm to 800 nm to investigate the transmittance and reflectance spectra. Linear optical parameters such as extinction coefficient k, refractive index n and both the real and imaginary parts: ∊real and ∊im of the dielectric permittivity were calculated as functions of the incident photon energy. The dispersion of the refractive index was fitted in terms of Cauchy formula and Wemple-DiDomenico single oscillator model. GHF crystals exhibited indirect optical interband transition and the optical energy gap Eg was determined by using Tauc plot. The indirect band gaps at elevated temperatures were determined and their temperature dependence was estimated. Optical band gap Eg values were found to decrease with an increase in crystal temperature; however, the band tail width exhibited opposite behavior. The nonlinear optical potential was examined by the second harmonic generation (SHG) test.

Published: January 2019

Abstract
In the current post-crisis period, the implementation of Corporate Governance principles has proven to be important. The Organization of Economic Cooperation and Development considers failure of Corporate Governance as one of the causes of the latest financial and economic crisis. We assume that the higher quality of institutional environment point to higher performance of the economy. The aim of the paper is to quantify the implementation of Corporate Governance in the European Union through selected qualitative indicators and his impact on economies. We have verified that countries with better values of judicial independence, protection of property rights, corruption, minority investor protection, extent of conflict of interest and resolving insolvency have a higher value of gross domestic product per capita. The index of enforcing contracts was statistically insignificant.

The objectiveis to study the results of different methods of surgical treatment of patients with infected pancreonecrosis and to conduct a comparative analysis of minimally invasive and traditional surgical interventions.Material and methods.The results of treatment of 206 patients with infected pancreonecrosis were analyzed. In accordance with the used method of surgical treatment, the patients were divided into 2 groups: 105 (51.0%) patients with “traditional” open interventions were included in the first group (comparison), and 101 (49.0%) patients treated with various miniinvasive technologies, or a combination of minimally invasive and “open” interventions were included in the second group.Results.It was found that the mortality rate in the second group was less than in the first group by 12.8% (p<0.05).Conclusion.Minimally invasive surgical techniques are the method of choice for delimited pancreatogenic ulcers. The use of combined surgical interventions leads to a significant reduction of postoperative mortality and duration of inpatient treatment.
