Published: April 2019

En este trabajo se aborda la temática del abuso sexual a niños, niñas y adolescentes y la importancia de la orientación familiar en la prevención de este abominable mal que azota con gran fuerza a una población vulnerable de la sociedad. Comprende un análisis de datos históricos de los orígenes de esta práctica hasta la incidencia de casos que en la actualidad se revelan en la realidad ecuatoriana, sobre todo. Se reflexiona sobre el preocupante aumento de casos que salen a la luz pública, así como también aquellos que no son expuestos y que son parte de una estadística oculta, pero que constituyen una realidad latente que urge ser tratada. Actualmente en un alto índice de familias es muy escaso el diálogo sobre temas de prevención de la violencia sexual infantojuvenil, en gran medida por tabúes, temores e idiosincrasias culturales y falta de capacitación, por lo que se concluye que, a partir de una mayor intervención a través de procesos técnicos, la orientación familiar podría ser un proceso clave para disminuir esta abominable práctica social.

THE FAMILY ORIENTATION IN THE PREVENTION OF SEXUAL ABUSE TO CHILDREN AND ADOLESCENTS

ABSTRACT

This paper addresses the issue of sexual abuse of children and adolescents and the importance of family guidance in the prevention of this abominable evil that strikes with great force a vulnerable population of society. It includes an analysis of historical data on the origins of this practice up to the incidence of cases that are currently revealed in the Ecuadorian reality, above all. It reflects on the worrying increase of cases that come to public light, as well as those that are not exposed and that are part of a hidden statistic, but that constitute a latent reality that urgently needs to be addressed. At present, in a high index of families, there is very little dialogue about prevention of sexual violence against children and adolescents, largely due to taboos, fears and cultural idiosyncrasies and lack of training, so it is concluded that, after a greater intervention Through technical processes, family counseling could be a key process to reduce this abominable social practice.

TO THE SOLUTION OF ISSUES OF NONSTATIONARY DIFFUSION IN LAYERED ENVIRONMENTS
Authors: Вендин Сергей , Vendin Sergey
Published: April 2019

The issues of nonstationary diffusion in layered structures are considered. When designing the devices for implementing mass transfer processes, it is necessary to take into account the properties of the substance and the nature of the processes. Design time reduces significantly and the efficiency of the devices is higher if a good physical model is built and a mathematical analysis with kinetics of the processes is applied. The difficulties of theoretical analysis and calculation of mass transfer are determined by the complexity of the transfer mechanism to and from the phase boundary. Therefore, simplified models of mass transfer processes are used in which the mass transfer mechanism is characterized by a combination of molecular and convective mass transfer. Many important practical problems involve the calculation of nonstationary diffusion (Fick's second law of diffusion) for a certain volume of substance (substances). For qualitative evaluation of processes, in the case of symmetry, volumetric issues can be considered as one-dimensional tasks, i.e. dependent on one coordinate. The general solution of the non-stationary diffusion equation for layered environments is proposed. The case of non-stationary boundary conditions of the third kind on the external surface and boundary conditions of the fourth kind conjugation for contiguous layers has been considered. The solution is obtained by separating the Fourier variables by the eigenfunctions of the problem using the Duhamel integral. The proposed solution is explicit and due to the recurrent form of the basic relations can be useful in numerical calculations
Inhibition of Proliferation by Knockdown of Transmembrane (TMEM) 168 in Glioblastoma Cells via Suppression of Wnt/β-Catenin Pathway

Published: April 2019

Human glioblastoma multiforme (GBM) accounts for the majority of human brain gliomas. Several TMEM proteins, such as TMEM 45A, TMEM 97, and TMEM 140, are implicated in human brain gliomas. However, the roles of TMEM168 in human GBM remain poorly understood. Herein we found that mRNA
levels of TMEM168 were overexpressed in GBM patients (n = 85) when compared with healthy people (n = 10), which was also supported by data from The Cancer Genome Atlas (TCGA). Kaplan‐Meier analysis of Gene Expression Omnibus dataset GSE16011
suggested that enhanced TMEM168 expression was associated with shorter survival time. To investigate whether and how TMEM168 functioned in the tumorigenesis of human GBM cells, two human GBM cell lines (U87 and U373) were used for study. Lithium chloride (LiCl), an activator for Wnt/β-catenin
pathway, was used for the treatment. Our data suggested that siRNA-TMEM168 (siTMEM168) prevented viability of U87 and U373 cells, induced cell cycle arrest (G0/G1 phase) and promoted apoptosis, and the mechanisms involved in blocking Wnt/β-catenin pathway, as evidenced
by reducing expression of β-catenin, C-myc, cyclin D1, and survivin. Furthermore, the inhibited effect of siTMEM168 on human GBM cell growth was significantly alleviated with additional LiCl treatment, substantiating the involvement of the Wnt/β-catenin pathway in this process. In
summary, our data demonstrated that TMEM168 may represent a therapeutic target for the treatment of human GBM.
The Role of Toll-Like Receptors in Oncotherapy
Authors: Liu Caiqi , Han Ci , Liu Jinfeng
Published: April 2019

Toll-like receptors (TLRs) are associated with tumor growth and immunosuppression, as well as apoptosis and immune system activation. TLRs can activate apoptosis and innate and adaptive immunity pathways, which can be pharmacologically targeted for the development of anticancer oncotherapies.
Several studies and clinical trials indicate that TLR agonists are promising adjuvants or elements of novel therapies, particularly when used in conjunction with chemotherapy or radiotherapy. An increasing number of studies suggest that the activation of TLRs in various cancer types is related
to oncotherapy; however, before this finding can be applied to clinical practice, additional studies are required. Research suggests that TLR agonists may have potential applications in cancer therapy; nevertheless, because TLR signaling can also promote tumorigenesis, a critical and comprehensive
evaluation of TLR action is warranted. This review focuses on recent studies that have assessed the strengths and weaknesses of utilizing TLR agonists as potential anticancer agents.

Published: April 2019

Using density functional theory, we study the electronic properties of several halide monolayers. We show that their electronic bandgaps, as obtained with the HSE hybrid functional, range between 3.0 and 7.5 eV and that their phonon spectra are dynamically stable. Additionally, we show that under an external electric field some of these systems exhibit a semiconductor-to-metal transition.
Tensile Strength of Porous Dust Aggregates
Authors: Tatsuuma Misako , Kataoka Akimasa , Tanaka Hidekazu
Published: April 2019

Comets are thought to have information about the formation process of our solar system. Recently, detailed information about comet 67P/Churyumov–Gerasimenko was found by Rosetta. It is remarkable that its tensile strength was estimated. In this paper, we measure and formulate the tensile strength of porous dust aggregates using numerical simulations, motivated by a porous dust aggregation model of planetesimal formation. We perform three-dimensional numerical simulations using a monomer interaction model with a periodic boundary condition. We stretch out a dust aggregate with a various initial volume filling factor between 10−2 and 0.5. We find that the tensile stress takes the maximum value at the time when the volume filling factor decreases to about half of the initial value. The maximum stress is defined to be the tensile strength. We take an average of the results with 10 different initial shapes to smooth out the effects of initial shapes of aggregates. Finally, we numerically obtain the relation between the tensile strength and the initial volume filling factor of dust aggregates. We also use a simple semi-analytical model and successfully reproduce the numerical results, which enables us to apply a wide parameter range and different materials. The obtained relation is consistent with previous experiments and numerical simulations about silicate dust aggregates. We estimate that the monomer radius of comet 67P has to be about 3.3–220 μm to reproduce its tensile strength using our model.
What Determines the X-Ray Intensity and Duration of a Solar Flare?
Authors: Reep Jeffrey W. , Knizhnik Kalman J.
Published: April 2019

Solar flares are observed and classified according to their intensity measured with the Geostationary Operational Environmental Satellite (GOES) X-ray Sensors. We show that the duration of a flare, as measured by the full width at half maximum (FWHM) in GOES is not related to the size of the flare as measured by GOES intensity. The durations of X-class flares range from a few minutes to a few hours, and the same is true of M- and C-class flares. In this work, we therefore examine the statistical relationships between the basic properties of flares—temperature, emission measure, energy, etc.—in comparison to both their size and duration. We find that the size of the flare is directly related to all of these basic properties, as previously found by many authors. The duration is not so clear. When examining the whole data set, the duration appears to be independent of all of these properties. In larger flares, however, there are direct correlations between the GOES FWHM and magnetic reconnection flux and ribbon area. We discuss the possible explanations, finding that this discrepancy may be due to large uncertainties in small flares, though we cannot rule out the possibility that the driving physical processes are different in smaller flares than larger ones. We discuss the implications of this result and how it relates to the magnetic reconnection process that releases energy in flares.
A Ground Plane Artifact that Induces an Absorption Profile in Averaged Spectra from Global 21 cm Measurements, with Possible Application to EDGES
Authors: Bradley Richard F. , Tauscher Keith , Rapetti David , Burns Jack O.
Published: April 2019

Most of the current Global 21 cm experiments include ground screens that help moderate effects from the Earth. In this paper, we report on a possible systematic artifact within the ground plane that may produce broad absorption features in the spectra observed by these experiments. Using analytical approximations and numerical modeling, the origin of the artifact and its impact on the sky-averaged spectrum are described. The publicly released EDGES data set, from which a 78 MHz absorption feature was recently suggested, is used to probe for the potential presence of ground plane resonances. While the lack of a noise level for the EDGES spectrum makes traditional goodness-of-fit statistics unattainable, the rms residual can be used to assess the relative goodness of fits performed under similar circumstances. The fit to the EDGES spectrum using a model with a simple two-term foreground and three cavity-mode resonances is compared to a fit to the same spectrum with a model used by the EDGES team consisting of a five-term foreground and a flattened-Gaussian signal. The fits with the physically motivated resonance and empirical flattened-Gaussian models have rms residuals of 20.8 mK (11 parameters) and 24.5 mK (9 parameters), respectively, allowing us to conclude that ground plane resonances constitute another plausible explanation for the EDGES data.
Petrophysical-mechanical behavior of Grisolia stone found in the architectural heritage of southern Italy
Authors: Forestieri G. , Alvarez de Buergo M.
Published: April 2019

Grisolia is one of the building stones most commonly found in the architectural heritage of southern Italy. Also known commercially as “gold stone” for its yellow intrusions, Grisolia was employed by the leading Calabrian schools of stonemasons, principally in the southern Italian regions of Calabria and Basilicata. It is an Upper Triassic crystalline carbonate quarried in the Verbicaro Unit on Calabria’s northern Tyrrhenian coast.

Possessing petrographic, physical and mechanical properties that ensure stone strength and durability, it is a high-quality building material suitable for structural and ornamental uses. These properties can be attributed to its low open porosity and excellent hydric behavior (low capillary water absorption), as well as to its high mechanical strength and low anisotropy. These characteristics make it recommendable as a building material for both restoration and new construction.

El objetivo de esta investigación ha sido estudiar el efecto inhibidor del CoO en ZnO obtenidos por síntesis por combustión de solución (SCS) cuando son incorporados a formulaciones alquídicas. ZnO y óxidos mixtos del tipo Zn1-xCoxO (donde x = 0,05-0,10-0,15-0,20) fueron obtenidos por SCS y caracterizados por XRD, ICP-OES, SEM y TEM. Los pigmentos fueron incorporados a imprimantes alquídicos medios en aceite en tres proporciones de 5%, 10% y 20% en peso pigmentos/resina. Probetas de acero protegidas con las formulaciones alquídicas fueron ensayadas en cámaras de niebla salina y dióxido de azufre. Asimismo, la eficiencia inhibidora de los pigmentos fue estimada mediante ensayos electroquímicos (método de Tafel) en solución 0,1 M de NaCl. Los resultados mostraron que el CoO mejora las propiedades inhibidoras de los nano-pigmentos base ZnO obtenidos por SCS.

Due to the huge development in the communication sector, science education has become very challenging. Inquiry-based science education (IBSE) has been proposed by academic leaders and policymakers as having the potential to increase student involvement and provide opportunities for the development of the key skills desired by employers in the future. Thirty teachers from 15 schools participated in the project and disseminated the knowledge obtained to their colleagues through peer-to-peer knowledge sharing. Most teachers expressed an increase in their understanding of IBSE, and 66% agreed that they received high-quality IBSE/EUPRB briefings. Students showed motivation to learn science and obtained scientific approaches and steps of answering their inquiries in order understand their surroundings, improve their achievement of scientific knowledge, build positive science attitudes, improve their understanding of the nature of science, and develop IBSE skills such as scientific data collection analyses, interpretation, and how to provide evidence to test ideas and develop theories.

Published: April 2019

Globalization refers to the integration of economic, social, political, cultural, and technological connections between countries. In this context, the concept of globalization includes every country and every social structure in the world with all its aspects. For this reason, the global influence of globalization can be said. Today, the irrefutable reality of the changing and transforming characteristics of the globalization process is accepted by the states, and determinations are made in this sense and measures are taken in the sense of negative effects. This change also affects international public finance. The common problems of the global world that arise in changing public finances are desired to be solved. In this chapter, different perceptions and dimensions of the phenomenon of globalization are examined. In this context, perceptions of globalization have been confused, and the dimensions of globalization and the problems brought about by these dimensions have been revealed.

Published: April 2019

Foreign aids are important for the development of poor countries. Therefore, in the literature, special attention is given to the analysis of foreign aids. This chapter investigates the factors affecting flow of foreign aids to developing and less developed countries and also welfare impacts on foreign aids. For this purpose, panel data on 71 countries receiving aids from Development Assistance Committee member countries are employed for the period between 1996 and 2013. The results show statistically significant impacts of real income per capita, trade openness, migration flows as a share of total population and governance measures. Moreover, although foreign aids are found to improve the welfare of receipt countries, for donor countries, results do not indicate any evidence of welfare effects. As a conclusion, the poverty, donor's interest represented by decline in migration flows, and governance quality are found to be significant determinants of foreign aid allocation.
Segmentation of Different Tissues of Brain From MR Image

Published: April 2019

In the most recent couple of decades, medical image processing stood out within picture preparing research fields because of its nonintrusive nature. Restorative imaging modalities, for example, MRI, CT filter, for the most part, rely upon computer imaging innovation to create or show advanced pictures of the inward organs of the human body, which causes the medicine professionals to envision the internal bits of the body. Here the proposed algorithm is thresholding different tissue type of brain MR image. Modes of the histogram represent different tissue types in brain MR image. So, this algorithm depends on the principle of finding maxima and minima using differentiation of the smoothed histogram. Using discrete differentiation, the author finds the multiple thresholds of brain MR image by selecting proper location of minima. The algorithm can be used as an initial segmentation of different tissue types of brain MR image for further accurate detection of the regions.

Cognitive and somatic health is predominantly congruous. Happiness creates a propitious impact on a person's wellbeing. Likewise, stress can be detrimental to a person's overall health. Nevertheless, it is perplexing to truly understand an emotional state of a patient for an unerring diagnosis. Considering the old adage, necessity is the mother of invention, there is a need for a sentimental and emotional analysis tool for the accurate identification of the mental state of the patient. Thus, Sentilyser was created. It is a clinical decision support system. Using the recorded voice of a person, the mood is analyzed using support vector regression. Arousal and valence of the audio file is calculated, and thus, the corresponding mood is predicted. The objective of this chapter is to propose the use of Sentilyser as a part of a patient's diagnosis, which will not only help the physician reach a better conclusion but will also help them in cases where the patients themselves are unaware about their own psychological state.

Authors: Nath Rakesh
Published: April 2019

Energy harnessing methods from rainwater using various smart materials have come into research, thus widening the scope of using these materials for the implementation in modern use. The piezoelectric materials present a brief idea of voltage generation whenever the material is deflected. The purpose of the study is to visualize an interconnection in parametric analysis of piezoelectric effect based energy harvester using two different commercially available piezoelectric materials, PZT-4A and PZT-5H, through series of implicit and explicit method simulations of FEM on COMSOL and ANSYS. The dynamic loads of different rainwater droplets sizes are investigated analytically. To calculate the variation of different methods in terms of deflection and voltage output, the implicit and multi-body explicit dynamic simulations are implemented separately.
