The premature deterioration of pavements due to the appearance of cracks that are reflected from lower layers is usually one of the frequent problems in rehabilitation tasks. Improving the performance and durability of the reinforcement layers, delaying the appearance of cracks, contributes to prolonging the useful life of those structures. This has been addressed by studying different technological alternatives, considering different materials interposed between the cracks and the new asphalt layers placed. It is for all this that, in the search for new materials that are capable of contributing to the aforementioned situation and analysing alternatives for greater reuse of end-of-life tires (NFU), in this work different types of mixtures have been evaluated, made with modified asphalts with high NFU rate. The analysis of their behaviour has made it possible to compare them and determine which presents the best performance for delaying the reflection of cracks on the surface. [ABSTRACT FROM AUTHOR]

The rheological and baking behavior of mixtures of wheat flour with cassava flour obtained from the CMC-40 variety was evaluated. A mixture design was used with wheat flour substitution levels between 6.25 and 25 %. Farinographic characterization of the mixtures was carried out and hardcrusted loaves breads were made. The following design response variables were taken: height, diameter, specific volume and the sensory attributes as typical odor and flavor, crunchiness and overall quality. The farinographic indicators of water absorption, stability and weakening varied with the maximum partial substitution of wheat flour for cassava flour, but not the development time, which did not change. Specific volume and sensory attributes were gradually affected with the increasing substitution of wheat flour for cassava flour. A mathematical model was obtained to explain the behavior of each of the response variables. From the optimization of the results, 10 possible solutions were obtained in which the proportions cassava flour were between 5 y 11,25 % and 11 % of cassava flour was selected as the maximum content for bread production.

The rheological study of ceramic clay hydro mixtures is essential to design equipment and washing processes. Hydro mixtures with clay concentrations of 15%, 25%, 35%, 45% and 55% by weight were analyzed and the correlation of shear stress as a function of the velocity gradient was obtained. It was observed that for concentrations up to 15%, the fluid, presents Newtonian behavior as well as ideal plastic behavior for higher concentrations. In order to estimate values of plastic viscosity, the decreasing dependence of maximum packing fraction of the mixture as a function of the clay concentration was determined. As a result, a general model is proposed for estimating the apparent viscosity of the hydro mixture during the ceramic clay washing process, which considers the clay concentration, dynamic viscosity coefficient of the hydro mixture water and the velocity gradient.

The aim of the present study was to examine the use of different mixtures of a-pinene (PN) and blueberry extract (EA) in coatings and assess their effects on strawberry post-harvest quality during storage (12 days). Coatings were made based on low acyl gellan (GBA) containing EA (50 mg/mL) and PN (300 µL/L). The results showed that the application of the coatings significantly decreased strawberry weight loss. The presence of EA reduced ΔE values in coated strawberries, since at the end of the storage period, coated strawberries (0.0PN/100EA) had a value of 7.45 while the value for uncoated strawberries was 17.77. Adding PN to coatings decreased Penicillium spp growth. In conclusion, GBA-based coatings containing mixtures of EA and PN can be used to preserve strawberries since they prevent fungal growth without reducing strawberry postharvest quality.

The use of different concentrations of a fructooligosaccharide (FOS) in the formulation of a flavored symbiotic fermented milk was evaluated. For this, the numerical optimization method was used through a design of the I-Optimal response surface of the mixture and to obtain the best concentration of adequate FOS in the formulation and guarantee the viability of the probiotic. The optimal formulation was characterized physicochemical, microbiological, rheological and sensory. It was confirmed that the flavored symbiotic fermented milk complied with the established quality parameters. The best concentration of FOS in the product formulation was 5% m/m and 3% m/m sugar. The cell viability of the probiotic (107) expressed that a product with functional characteristics was obtained with a positive effect on human health, complying with the quality indexes expected for the product. The microbiological indicators evidenced the good hygienic sanitary quality of the product. [ABSTRACT FROM AUTHOR]

This article proposes a new generic label for Tacitus' Germania as "frontier ethnography". Our reading is supported by Germania's textual instability, due to its topical originality and compositive innovation. Although these features place Germania in a disruptive positioning face of historiographical tradition of Monography, it is consistent with the particular rhetorical situation of the late first century AD, traversed by the mixture of genres and the inversion of center-periphery relationships, and with the rise of a new dynasty as well. These characteristics are found in the two main text features of Germania. On the one hand, Ethnography, which was traditionally relegated to the excursus, is used here as the text's main narrative device, whereas historical discourse is relocated to the digression. On the other hand, Barbaric periphery beyond the frontier becomes the central narrative matter of the text. Therefore, these textual features allow us to state that Germania insinuates a discourse move towards the limits of Roman generic and geographical space. Hence, Tacitus' Germania can be interpreted as a literary exercise representing a new space within its sociopolitical context: the frontier. [ABSTRACT FROM AUTHOR]

In this work, an empirical model is generalized to predict the thermal conductivity of ionic liquids. Initially, experimental data are collected, which include different types of anions and cations. A total of 38 ionic liquids are evaluated (28 substances for correlation and 10 substances for prediction), which corresponds to 265 experimental data. The temperature ranges vary between 273 and 390 K at atmospheric pressure (1 atm). The model is generalized using 215 experimental data, and the average deviation is around 4.72%. Then, the predictive capabilities are evaluated in 50 experimental data with an average deviation of 3.48%. The generalized model is extended to binary mixtures using a simple mixing rule with an interaction parameter, and the absolute deviation is 0.77%. Finally, the generalized model is compared with others developed in the literature, and the statistical analysis shows that it provides acceptable results. [ABSTRACT FROM AUTHOR]

Objective. Evaluate the effect of spatial repellency against Ae. aegypti of two chemical compounds impregnated in different types of fabrics. Materials and methods. The study was carried out in the year 2015-2016 in the Centro Regional de Investigación en Salud Pública, del Instituto Nacional de Salud Pública. The high-throughput screening system was used to evaluate the response of Ae. aegypti to transfluthrin and linalool, impregnated individually at different concentrations in poplin, cotton and polyester. The effect of their mixtures was also determined, washing on residuality and percentage of protection. Results. The highest spatial repellency response was for 0.1% linalool-cotton treatment (RE = 70 ± 5.77%). The mixture of 0.1% linalool and 0.001% transfluthrin presented a similar spatial repellence percentage for the three types of fabric. The transfluthrin-poplin treatment 0.001% maintained a residual of five days. 0.1% linalool produced a 62.50% protection in the presence of an attraction stimulus. Conclusion. It is suggested the impregnation of 0.1% linalool in clothing as a protection measure for Ae. aegypti. [ABSTRACT FROM AUTHOR]

The present investigation was developed with the objective of valuing the energy potential of the available agroindustrial residuals of tomato in the Factory "19 de Abril" of Mayabeque province, for the biofuel production. It was carried out the characterization of the residual mixtures of tomato through physical-chemical and energy indicators to estimate the energy potential that would be contributed starting from their use in the bio-ethanol obtaining; in turn the necessary conditions were valued for the recycled of these residuals. Starting from the gathered information and the identification of the agroindustrial residuals generated in the factory, it was evidenced that the tomato residuals are those that bigger frequency and quantity present. The physical-chemical characterization of these residuals evidenced the necessity to use indirect roads of prosecution, as well as the formation of mixtures with other residuals obtained in this factory that it optimizes the prosecution conditions. As main result it was considered the energy potential of the mixture of the available agroindustrial residuals of tomato, being evidenced the possibility of bioethanol production, starting from the adaptation of the methods of prosecutions, conditions and alternative to the characteristics of the residual mixture and those of the means where it is developed in a viable and sustainable prosecution. It is recommended for future studies to identify the most efficient process and to improve the way and the conditions of storage of the residuals in the factory for their possible recycled.

To increase the efficiency of the independent component analysis (ICA) and reduce the computational complexity of the system, this paper proposes a methodology based on the compressive sampling with minimum measurements. This allows compressing and modifying the Gaussian characteristics of audio signals. ICA is one of the most widely used schemes for separating the sources involved in an audio mixture received in a set of sensors. However, for proper operation it is required that the signals involved in the mixture do not have Gaussian characteristics or at most only one of them be Gaussian, characteristics that are not satisfied by the audio signals, which have in general Gaussian characteristics. The proposed methodology allows obtaining a better separation with lower computational complexity, and with a more efficient separation of the mixed signals, even if the signals involved in the mixture are of Gaussian toe.

A viscosity model based on the Peng-Robinson cubic equation of state is applied. The model has been used to correlate and predict viscosities of pure substances and mixtures especially in the saturation zone. The parameters of the model are generalized in terms of the molar mass. The generalized expressions are estimated by fitting the experimental data for a group of alkanes and alcohols. Average deviations between calculated values and experimental data for alkanes and alcohols are 6.26% and 7.21%. Some predictive calculations are performed for alkanes and alcohols finding average absolute deviation of 3.99% and 13.76%. To extend the model to mixtures, some binary mixtures calculations are performed using three mixing rule approaches. The results obtained with the simple, one and two interaction parameters mixing rules are 18.66%, 10.31% and 3.85%. The results indicate that the new viscosity model provides results that can be considered adequate and consistent taking in account the simplicity of the generalized expressions.

In this study a Multi-Purpose Evolutionary Algorithm (AEMO) was developed to determine the optimum mixtures of these materials with lime and cement to use these mixtures as construction material. The objective is to compensate for the environmental impact of the extraction of these materials of carbon open mines, applying the mixtures to stabilize roads. Two objective functions were established: to maximize soil support capacity and minimize costs, with restrictions associated with granulometry, plasticity and additive costs. It is shown that these materials can be used for bond material, subbase and/or fill with a pre-treatment of the granulometry and an adjustment of the percentages of the lime. (between 2 and 4 %) and cement (less than 1%) by applying the AEMO, leaving the California Bearing Ratio (CRB) and plasticity index within the appropriate range. [ABSTRACT FROM AUTHOR]

We present a didactic experiment of desiccation using starch-water mixture. The aim is to obtain prismatic joints similar to columns in basalt lava flows, or the desiccation fractures in sediments. Two types of joints were observed in experiments: a) the first formed joints are large, crossing completely the container used in the experiment. The intersection angles among the large joints are about 90°; b) The second joints are smaller; they develop after the large ones forming intersection angles from 90° to 140°. Both large and small joints have dips near 90° with respect the dissection surface. Using Voronoi diagrams we explained patterns which resemble the prismatic joints obtained in the experiment.
