A simple synthetic route for the preparation of a reversed-phase stationary phase based on monosized-porous hydrogel beads and its chromatographic use for separation of small molecules
Authors: Çelebi B.
Published: April 2016

New polyacrylate-based monosized-porous polymer beads were proposed as a stationary phase for the separation of polar compounds by microbore reversed-phase chromatography. For this purpose, monosized-porous poly(glycerol dimethacrylate-co-glycerol-1,3-diglycerolate diacrylate), poly(GDMA-co-GDGDA), beads with hydroxyl functionality were synthesized by a modified seeded polymerization. The selected octadecylating agent, stearoyl chloride (SC), was covalently attached onto the hydrophilic beads via a direct, single stage reaction with a simple synthetic route. SC attached-poly( GDMA-co-GDGDA) beads were slurry-packed into the microbore columns and used as separation medium microbore reversed-phase chromatography. The stationary phase was used for separation of alkylbenzenes and polar analytes by micro reversed-phase chromatography, using mobile phases with low acetonitrile content. Theoretical plate number (TPN) values up to 12,000 plates m−1 and 10,000 plates m−1 for alkylbenzenes and polar analytes, respectively, were achieved. The results also showed that poly(GDMA-co-GDGDA) hydrogel beads are a promising starting material for a number of chromatographic applications like reversed-phase (RP) chromatography, hydrophilic interaction chromatography (HILIC), ion-exchange chromatography (IEC), and affinity chromatography with a single-stage surface modification.

Published: April 2016

Engineering problems involve the solution of large sparse linear systems, and require therefore fast and high performance algorithms for algebra operations such as dot product, and matrix-vector multiplication. During the last decade, graphics processing units have been widely used. In this paper, linear algebra operations on graphics processing unit for single and double precision (with real and complex arithmetic) are analyzed in order to make iterative Krylov algorithms efficient compared to central processing units implementation. The performance of the proposed method is evaluated for the Laplace and the Helmholtz equations. Numerical experiments clearly show the robustness and effectiveness of the graphics processing unit tuned algorithms for compressed-sparse row data storage.

Authors: Katona Tamas J.
Published: April 2016

Experience shows that the nuclear power plant can be safely designed for vibratory effects of earthquakes. Contrary to this, the plants can be heavily damaged by effects of earthquake-induced phenomena like tsunami, soil liquefaction after surviving the ground shaking effects. In the paper, the nuclear power plant’s safety analysis methodology is outlined for the case of soil liquefaction. In the paper the methodology for safety analysis of nuclear power plants for the case of liquefaction is outlined for both deterministic and probabilistic cases. It is shown, how the analysis of consequences of the liquefaction has to be embedded into the overall analysis of plant seismic safety. The selection of hazard and the fragility assessment methods is discussed from the point of view of needs of safety analysis.

Published: April 2016

Gold nanoparticles can be used as ultimate electrical materials for storing electrons or controlling their flow for the next generation nano-electronic devices. These particles are the core element of assemblies where the electrical current is reduced to the smallest possible since electrons are controlled one by one by using the Coulomb blockade phenomenon. We prepared colloidal gold nanoparticles beteween 4 and 15 nm and grafted them on a grafted organic monolayer (GOM) on silicon. GOM are highly ordered monolayers prepared by hydrosilylation of alkene molecules and subsequently modified with an amine group so that gold nanoparticles can be firmly immobilized on top of the layer. We discuss several electrical properties at a single electron level. Using the conductive tip of KPFM, we were also able to reveal the spontaneous charging behavior of the gold nanoparticles so that the local work function of a 10 nm gold nanoparticle is only 3.7 eV. By placing an STM tip above a nanoparticle, Coulomb blockade allows controlling the number of electrons simultaneously injected in the nanoparticle. This opens the way for new kinds of single electron memories or single electron transistors.

Authors: Balcázar-Pérez M.A. , Ramírez-García G. , Gutiérrez S. , Galindo R.
Published: April 2016

Magnetic nanoparticles (MNPs) are a class of materials that can be manipulated under the influence of an external magnetic field. Thanks to the ability of the MNPs to be guided by an external magnetic field that is like "action at a distance", combined with their low cytotoxicity and the intrinsic penetrability of magnetic fields into human tissue, opens up many applications involving the transport and/or immobilization of biological entities [1, 2].

This work is focused on the synthesis of magnetite nanoparticles by varied methods, their functionalization with nickel tetrasulfonated phthalocyanine, and the corresponding physicochemical characterization and colloidal stability studies in biologically compatible media. The in vitro production of singlet oxygen by these nanoparticles through photochemical stimulation in ultraviolet and visible region was evaluated, resulting in 4.5 and 4 µM respectly to magnetite synthetized in the group. The increase reactive oxygen species concentration in the cellular environment can result in modification and damage of cellular components, and potentially, cell death and necrosis. Therefore, these materials offer the promise of revolutionary tools for photodynamic therapy and hyperthermia, which are attractive strategies for cancer therapy without systemic toxicity.

Published: April 2016

The characteristics of silicon films deposited by plasma depend strongly on the reactor parameters. In our experiments, the two-level factorial design was implemented. Pressure, silane and hydrogen flows were set at high and low values for the synthesis of silicon films. Results showed that the flows of silane and hydrogen played a key role, being the influence of pressure low. In particular, the samples at high level of hydrogen exhibited the lowest deposition rate and photosensitivity. On the other hand, the samples at low level of hydrogen showed crystalline regions and high deposition rate. For the lowest dilution ratio, nano/meso-structured silicon films were obtained, showing high photosensitivity and high roughness that increases the scattering of light. These characteristics of our films make them suitable to be used in photovoltaics.

Published: April 2016

In this study, it was adjusted a mathematical model to measure the effect of electric motor efficiency on pumping system costs for irrigation on the tariff structure of conventional electricity and green horo-seasonal , and also to calculate the recovery period of the invested capital in higher efficiency equipment. Then, it was applied to a center pivot irrigation system in two options of electric motor efficiency, 92,6% (standard line) and 94,3% (high efficiency line), and the acquisition cost of the first corresponded to 70% the of the second. The power of the electric motor was 100hp. The results showed that the model allowed us to evaluate if a high efficiency motor was economically viable compared to the standard motor in each tariff structure. The high efficiency motor was not viable in the two tariff structures. In the green horo-seasonal tariff, would only be viable if its efficiency was 4.46% higher than the standard motor. In the conventional tariff, it would only be viable if the efficiency overcame 2.71%.

Published: April 2016

The Brazil's Biodiesel Production and Use Program introduces biodiesel in the Brazilian energy matrix, bringing along the perspective of a growth of the glycerin offer, co-product generated in the proportion of 10 kg for each 100 L of biodiesel. The aim of this study was to evaluate the addition of crude glycerin in the anaerobic digestion of cassava starch industry effluent (cassava wastewater), in a horizontal semi-continuous flow reactor of one phase in laboratory scale. It was used a reactor with a 8.77 L of useful volume, a medium support for corrugated conduit of polyvinyl chloride (PVC), temperature of 261 ºC, fed with cassava wastewater and glycerin, with hydraulic detention times of 4 and 5 days and increasing volumetric organic load of 3.05; 9.32; 14.83 and 13.59 g COD L-1 d-1, obtained with the addition of glycerin at 0; 2; 3 and 2% (v/v), respectively. The average removal efficiencies of TS and TVS were decreasing from the addition of glycerin to the cassava wastewater, averaging 81.19 to 55.58% for TS and 90.21 to 61.45% for TVS. The addition of glycerin at 2% increased the biogas production compared to the control treatment, reaching 1.979 L L-1 d-1. The biogas production as a function of the consumed COD was higher for the control treatment than for the treatments with addition of glycerin, which indicates lower conversion of organic matter into biogas.
Swine manure post-treatment technologies for pathogenic organism inactivation
Authors: Bilotta Patrícia , Kunz Airton
Published: April 2016

Swine manure agricultural use is a common practice in Brazil. Their physic-chemical characteristics favor its use as biofertilizer, but the presence of pathogens may become a risk to human health. This research presents a qualitative study of the main alternatives of pig manure disinfection, analyzing efficiency, advantages and limitations of each procedure. The disinfection studies reported in literature are based on the following treatments: alkaline, thermal, biological, chemical, and physical. The greater efficiencies are in thermal treatment (> 4 log: 60 °C), chemical treatment (3 to 4 log: 30mg Cl- L-1; 3 to 4 log: 40 mg O3 L-1) and physical treatment (3 a 4 log: 220 mJ UV radiation cm-2). The biological treatment (anaerobiosis) also promotes the pathogen reduction of swine manure, however with lower efficiency (1 to 2 log). The selection of the treatment should consider: implementation and operation cost, necessity of preliminary treatment, efficiency obtained and destination of the treated manure (agricultural use, water reuse). Brazilian regulation does not have specific guidelines for the microbiological quality of animal production effluents that is very important to be considered due to confined animal feeding operation transformation in the last years in the country.

Authors: Gorbaniuk Oleg , Rożnowski Bohdan , Biela Adam , Biela-Warenica Maria
Published: April 2016

The safety performance of road drivers requires an improvement of the mechanism of selecting candidates for professional drivers. Unfortunately, it has been common practice until now to design diagnostic methods to reflect the theoretical constructs of traits and abilities considered useful in road traffic. We decided to adopt the opposite, complementary approach and to analyze what the methods used in Polish transport psychology really measure and what theoretical constructs that corresponds to. The results will be treated as a first step towards determining the prognostic validity of these psychometric tools. We tested 300 professional male drivers, aged form 21 to 65 years, belonging to six groups of equal size: victims of collisions, victims of accidents, perpetrators of collisions, perpetrators of accidents, drivers stopped by the police for drunk driving and those who had never been involved in any of the above situations. The analysis concerned 27 indicators taken from nine diagnostic tools commonly used by transport psychologists in Poland. Exploratory factor analysis was performed to determine the latent factor structure of these methods. The Kaiser criterion allowed us to identify the eight-factor solution as the optimal one. The extracted factors are: attention, accuracy in visual perception, mental alertness, sense of community, efficiency of reactiveness and decision making, cognitive abilities (logical induction and grasping analogy), agency, and sensitivity to social approval.

Authors: Dumitru Florina Diana , Moncea Mihaela Andreea , Higuera-Cobos Oscar Fabián
Published: April 2016

Samples of as-extruded ZK60 magnesium alloy were subjected to 6 passes of equal-channel angular pressing (ECAP) following route A. The processing temperature was decreased with the number of passes. The structural evolution of the deformed samples was analyzed using Electron Backscattered Diffraction (EBSD) and X-Ray Diffraction. The grain boundary misorientation distribution showed a reduction in the grain size accompanied by
a large proportion of high angle grain boundaries and the presence of recrystallization processes. XRD results showed that with the increment of the applied strain the peaks presented a slight variation of the angles.

Authors: Flórez-García Luis Carlos , González-Rojas Hernán Alberto , Casado-López Rámon
Published: April 2016

El corte asistido por vibración (CAV) es una técnica de mecanizado que brinda mejor acabado superficial, reduce fuerzas en el corte y aumenta la vida de la herramienta. Para predecir de forma geométrica la topografía de un cilindrado con CAV se ha construido un programa que simula la topografía superficial con el propósito de realizar barridos sobre la frecuencia de vibración, para observar el comportamiento de los parámetros superficiales Sa, St, Ra, Rt y de la topografía. Se ha podido observar que los parámetros superficiales tienen un comportamiento periódico, caracterizado por una frecuencia adimensional igual a 1.

Se expone el resultado del diagnóstico de seguridad informática realizado a una organización privada en el departamento de Boyacá (Colombia), y de la creación y aplicación de un plan de gestión de vulnerabilidades diseñado a la medida de las necesidades de dicha organización. Se inició la investigación con el levantamiento del inventario tecnológico de la empresa, para identificar los problemas que pueden causar alguna vulnerabilidad que afecte la seguridad de la información. Tras una etapa de 6 meses de monitoreo del plan de gestión dentro de la empresa, se evidenció la efectividad de éste, pues se logró una reducción del 70% en las vulnerabilidades, con la aplicación de algunos remedios previamente diseñados. Por otro lado, en el artículo se muestran algunos cuadros comparativos de herramientas informáticas que fueron seleccionadas y utilizadas en la aplicación de las etapas del plan de gestión, ya que pueden ayudar a investigaciones futuras a la selección de herramientas para el monitoreo y gestión de vulnerabilidades.
Valoración del residuo de piedra para preparar concreto para senderos peatonales: caso piedra Barichara
Authors: Serrano-Guzmán María Fernanda , Pérez-Ruíz Diego Darío , Sarmiento-Gómez Mateo
Published: April 2016

Los indicadores de desarrollo de un país están asociados a la satisfacción de las necesidades básicas de la población y de otras complementarias, como las relacionadas con la  infraestructura vial, que favorecen la competitividad de las regiones. En algunos países en vía de desarrollo es marcado el bajo porcentaje de vías pavimentadas, con la consecuente repercusión económica que la falta de conectividad genera. Por tal razón, se hace necesario ejecutar proyectos que mejoren el estado de las vías, con alternativas que protejan la capa de afirmado. 
Las lajas de piedra acomodadas con los criterios constructivos de pavimento articulado son opciones viables en aquellos sectores en donde abunda la roca. Barichara, municipio de Santander (Colombia), es una zona caracterizada por la calidad de la piedra que se extrae de manera manual y que se aprovecha para decoración y como material de revestimiento. Durante el proceso de extracción de la piedra, además de afectar la salud del personal encargado de esta labor, se genera un subproducto que impacta negativamente el paisaje. En este estudio se demuestra que la trituración del residuo del proceso de extracción de la piedra permite generar un material aprovechable en mezclas de concreto para senderos peatonales y como mortero de pega de baldosas en área de bajo tránsito.

La Computación en la Nube, nueva tecnología que ha permitido desplegar un mercado de servicios de computación por demanda, ha adquirido gran popularidad, lo que ha llevado a que muchos directivos de empresas y departamentos de tecnología deseen adquirir soluciones basadas en ella, a pesar de que aún no tienen claro cómo deberían contratarlas. La metodología y las recomendaciones detalladas en este documento se basan principalmente en las mejores prácticas de ITIL v3, TMF (eTOM) y de definición de Acuerdos de Nivel de Servicio (ANS), teniendo en cuenta criterios como continuidad, disponibilidad, calidad y seguridad del servicio, entre otros. Los resultados obtenidos al usar el CTP (Costo Total de Propiedad) como herramienta financiera para la toma de decisiones en proyectos de tecnología dio como resultado un claro beneficio económico al optar por la computación en la nube.

Estudio técnico-ambiental de las estructuras principales de fortificación usadas en la minería de carbón de Norte de Santander
Authors: Bolívar-León Rafael , Triviño-Jaimes Neyl Richard , García-Mogollón Javier Mauricio
Published: April 2016

La caracterización de las estructuras de fortificación en la minería de carbón en Norte de Santander (Colombia) y el aporte de este sector a la deforestación han sido poco estudiados. La pérdida de bosques entre 1990 y 2010 en el departamento fue del 26%, y la contribución a ella de la minería de carbón, es de 0,36%. Se determinaron 17 variables geométricas de la estructura, de las cuales sólo dos influyen en el comportamiento mecánico de la estructura. Mediante una simulación estructural y un diseño de experimentos 25 , se obtuvo un diagrama para la selección del diámetro y el ángulo, el cual garantiza teóricamente un mejor aprovechamiento de la madera. Se podrían aprovechar diámetros de madera tan pequeños como 14 cm. sin detrimento de las propiedades mecánicas del diseño, conllevando un posible menor tiempo de tala de árboles, menor costo de transporte y mayor facilidad de montaje dentro de la mina.
