The weak convergence theorem is established.
A Novel Interaction Network Used by Potyviruses in Virus–Host Interactions at the Protein Level
Authors: Ala-Poikela Marjo , Rajamäki Minna-Liisa , Valkonen Jari P.T.
Published: December 2019

Host proteins that are central to infection of potyviruses (genus Potyvirus; family Potyviridae) include the eukaryotic translation initiation factors eIF4E and eIF(iso)4E. The potyviral genome-linked protein (VPg) and the helper component proteinase (HCpro) interact with each other and with eIF4E and eIF(iso)4E and proteins are involved in the same functions during viral infection. VPg interacts with eIF4E/eIF(iso)4E via the 7-methylguanosine cap-binding region, whereas HCpro interacts with eIF4E/eIF(iso)4E via the 4E-binding motif YXXXXLΦ, similar to the motif in eIF4G. In this study, HCpro and VPg were found to interact in the nucleus, nucleolus, and cytoplasm in cells infected with the potyvirus potato virus A (PVA). In the cytoplasm, interactions between HCpro and VPg occurred in punctate bodies not associated with viral replication vesicles. In addition to HCpro, the 4E-binding motif was recognized in VPg of PVA. Mutations in the 4E-binding motif of VPg from PVA weakened interactions with eIF4E and heavily reduced PVA virulence. Furthermore, mutations in the 4G-binding domain of eIF4E reduced interactions with VPg and abolished interactions with HCpro. Thus, HCpro and VPg can both interact with eIF4E using the 4E-binding motif. Our results suggest a novel interaction network used by potyviruses to interact with host plants via translation initiation factors.

Published: December 2019

As a result of the inexorable development of the economy and the ever-increasing population, the demand for water in the urban and rural sectors has increased, and this in turn has caused the water quality and eutrophication of the reservoir to become a legitimate concern in the water environment management of river basins. Phosphorus (P) is one of the limiting nutrients in aquatic ecosystems; P in the sediment is a primary factor for eutrophication. Yuecheng Reservoir is located in one of the most productive and intensively cultivated agricultural regions in North China. Detailed knowledge of the sediment is lacking at this regional reservoir. The first study to look into the different P fractions and its diffusion fluxes at the water sediment interface of the Yuecheng Reservoir makes it possible to learn about the internal P loading. According to the results, the concentrations of total phosphorus (TP) ranged from 1576.3 to 2172.6 mg kg and the P fraction concentration sequence is as follows: P associated with calcium (Ca–Pi) > organic P (Po) > P bound to aluminum (Al), ferrum (Fe) and manganese (Mn) oxides and hydroxides (Fe/Al–Pi). The results demonstrated that, although the construction of a large number of water conservancy projects in the upper reaches of the river resulted in the decrease of inflow runoff, the pollutions from terrestrial plants or materials played a key role in the sediment phosphorus fraction, and they should be emphasized on the water environment management of river basin.
Transmissibility Upscaling on Unstructured Grids for Highly Heterogeneous Reservoirs
Authors: Guérillot Dominique , Bruyelle Jérémie
Published: December 2019

One critical point of modeling of flow in porous media is the capacity to consider parameters that are highly variable in space. It is then very challenging to simulate numerically fluid flow on such heterogeneous porous media. The continuous increase in computing power makes it possible to integrate smaller and smaller heterogeneities into geological models of up to tens of millions of cells. On such meshes, despite computer performance, multi-phase flow equations cannot be solved in an acceptable time for hydrogeologists and reservoir engineers, especially when the modeling considers several components in each fluid and when taking into account rock-fluid interactions. Taking average reservoir properties is a common approach to reducing mesh size. During the last decades, many authors studied the upscaling topic. Two different ways have been investigated to upscale the absolute permeability: (1) an average of the permeability for each cell, which is then used for standard transmissibility calculation, or (2) computing directly the upscaled transmissibility values using the high-resolution permeability values. This paper is related to the second approach. The proposed method uses the half-block approach and combines the finite volume principles with algebraic methods to provide an upper and a lower bound of the upscaled transmissibility values. An application on an extracted map of the SPE10 model shows that this approach is more accurate and faster than the classical transmissibility upscaling method based on flow simulation. This approach keeps the contrast of transmissibility values observed at the high-resolution geological scale and improves the accuracy of field-scale flow simulation for highly heterogeneous reservoirs. Moreover, the upper and lower bounds delivered by the algebraic method allow checking the quality of the upscaling and the gridding.

Published: December 2019

Rainfall thresholds define the conditions leading to the triggering of shallow landslides over wide areas. They can be empirical, which exploit past rainfall data and landslide inventories, or physicallybased, which integrate slope physical–hydrological modeling and stability analyses. In this work, a comparison between these two types of thresholds was performed, using data acquired in Oltrepò Pavese (Northern Italian Apennines), to evaluate their reliability. Empirical thresholds were reconstructed based on rainfalls and landslides triggering events collected from 2000 to 2018. The same rainfall events were implemented in a physicallybased model of a representative testsite, considering different antecedent pore-water pressures, chosen according to the analysis of hydrological monitoring data. Thresholds validation was performed, using an external dataset (August 1992–August 1997). Soil hydrological conditions have a primary role on predisposing or preventing slope failures. In Oltrepò Pavese area, cold and wet months are the most susceptible periods, due to the permanence of saturated or close-to-saturation soil conditions. The lower the pore-water pressure is at the beginning of an event, the higher the amount of rain required to trigger shallow failures is. physicallybased thresholds provide a better reliability in discriminating the events which could or could not trigger slope failures than empirical thresholds. The latter provide a significant number of false positives, due to neglecting the antecedent soil hydrological conditions. These results represent a fundamental basis for the choice of the best thresholds to be implemented in a reliable earlywarning system.
Oil-Water-Gas Three-Phase Separation in Multitube T-Junction Separators

Published: December 2019

Multitube T-junctions can be used as an oil-water-gas pre-separator in the oil and gas industry. In this paper, the mixture model, coupled with the k-ε turbulent model, was applied for a simulation of the oil-water-gas three-phase flow characteristics in the multitube T-junction separator. The oil droplet size ranged from 1 to 4 mm. The water content ranged from 5% to 20% and the gas content from 3% to 25%. According to the phase separation results for different droplet sizes, it was found that, as the oil droplet size increased, the water content at the water outlet initially increased and then tended to be stable. Therefore, it was necessary to increase the oil droplet size through corresponding measures before flowing into the T-junction for separation. For the separator with an inner diameter of 50 mm, the oil content at the inlet had a great influence on the water-oil separation performance, and the water-oil separation performance was obviously improved as the oil content decreased. Owing to increased residence time, the oil content had little influence on the water-oil separation performance when the separator with an inner diameter of 100 mm was applied. Moreover, for the separator with an inner diameter of 100 mm, the oil content had little influence on the degassing effect, and more than 90% of the gas could be discharged from the gas outlet. The separation performance of the multitube T-junction separator became worse as the inlet gas content increased.

Published: December 2019

Saudi Arabia’s arid and semi-arid regions suffer from water scarcity because of climatic constraints and rapid growth of domestic and industrial water uses. The growing demand for high-quality water supplies and to reduce the dependency on desalination creates an urgent need to explore groundwater resources as an alternative. The weighted overlay analysis method using the fuzzy-analytical hierarchy process (FAHP) multi-criteria decision making (MCDM) techniques combined with geoinformation technology was used in this study to explore the groundwater potential zones in the Itwad-Khamis watershed of Saudi Arabia. Twelve thematic layers were prepared and processed in a GIS setting to produce the groundwater potential zone map (GPZM). Subsequently, potential groundwater areas were delineated and drawn into five classes: very good potential, good potential, moderate potential, poor potential, and very poor potential. The estimated GWPZ (groundwater potential zones) was validated by analyzing the existing open wells distribution and the yield data of selected wells within the studied watershed. With this quality-based zoning, it was found that 82% of existing wells were located in a very good and good potential area. The statistical analysis showed that 14.6% and 28.8% of the total area were under very good and good, while 27.3% and 20.2% were accounted for the moderate and poor potential zone, respectively. To achieve sustainable groundwater management in the Aseer region, Saudi Arabia, this research provided a primary estimate and significant insights for local water managers and authorities by providing groundwater potential zone map.

Published: December 2019

Survival models can support the estimation of the resources needed for future renovations of sewer systems. They are particularly useful, when a large share of network will need renovation. This paper studies modelling sewer deterioration in a context, where data are available for pipes selected for inspections due to suspected or experienced poor condition. We compare the random survival forest and the Weibull regression for modelling survival and find that both methods yield similar results, but the random survival forest performs slightly better. We propose a method for estimating the range in which the actual network survival curve lies. We conclude that in order to reach reliable results, a life span model needs to be constructed based on a random sample of pipes, which are then consecutively inspected and in addition, censoring and left truncation need to be accounted for. The inspection data applied in this paper had been collected with the aim of finding pipes in poor condition in the network. As a result, the data were biased towards poor condition and unrepresentative in terms of pipe ages.

Published: December 2019

Background

High demand for health services is an issue of current importance in England, in part because of the rapidly increasing use of emergency departments (EDs) and GP practices for mental health conditions and the high cost of these services.

Aim

To examine the social determinants of health service use in people with mental health issues.

Design and setting

Twenty-eight neighbourhoods, each with a population of 5000–10 000 people, in the north west coast of England with differing levels of deprivation.

Method

A comprehensive public health survey was conducted, comprising questions on housing, physical health, mental health, lifestyle, social issues, environment, work, and finances. Poisson regression models assessed the effect of mental health comorbidity, mental and physical health comorbidity, and individual mental health symptoms on ED and general practice attendances, adjusting for relevant socioeconomic and lifestyle factors.

Results

Participants who had both a physical and mental health condition reported attending the ED (rate ratio [RR] = 4.63, 95% confidence interval [CI] = 2.86 to 7.51) and general practice (RR = 3.82, 95% CI = 3.16 to 4.62) more frequently than all other groups. Having a higher number of mental health condition symptoms was associated with higher general practice and ED service use. Depression was the only mental health condition symptom that was significantly associated with ED attendance (RR = 1.41, 95% CI = 1.05 to 1.90), and anxiety was the only symptom significantly associated with GP attendance (RR = 1.19, 95% CI = 1.03 to 1.38).

Conclusion

Mental health comorbidities increase the risk of attendances to both EDs and general practice. Further research into the social attributes that contribute to reduced ED and general practice attendance rates is needed.

Évaluation du rôle du fer structural sur la cristallinité des kaolinites
Authors: Mestdagh Michèle M. , Herbillon Adrien-Jules , Rodrique Luc , Rouxhet Paul G.
Published: December 2019

This paper deals with 24 kaolinite samples whose content in Fe₂O₃ varies from zero up to about 2 %. Though iron can also be accomodated in ancillary minerals (such as titanium oxides and micas) contaminating the kaolinite, the selected samples proved to be representative of kaolinites with different contents in structural iron. The treatment of the ESR iron spectra of these kaolinites permits the quantitative identification of two types of iron sites, called here E iron and I iron. The content in E iron is not correlated to the degree of kaolinite crystallinity. In contrast, the content in I iron is directly related to the proportion of defects due to the displacement of the vacant site in the octahedral sheet. When occurring in kaolinite, such defects induce the formation of domains whose hydroxylic configuration becomes similar to that of dickite. In any kaolinite, the proportion of such domains can be identified by the quantitative treatment of features of the OH stretching vibration bands of its infrared spectrum. The results show that a multiple relation exists between the proportion of defects due to a vacancy displacement, the content in I iron and the proportion of domains showing a hydroxylic configuration similar to that of dickite. The most disordered kaolinites are characterized by an I iron content of about 1 % (expressed in Fe₂O₃) and a proportion of dickite-like domains of about 50 %.
Pétrologie des nodules de pyroxénolites associés à la rushayite d'In Teria (N. E. d'Illizi, ex Fort Polignac), Algérie
Authors: Bossière Gérard , Megartsi M'hamed
Published: December 2019

Ce travail présente la première étude pétrologique effectuée sur les pyroxénolites associées à une variété nouvelle de rushayite découverte en 1971. Les caractères chimiques des minéraux constitutifs conduisent à interpréter les pyroxénolites comme des cumulats de haute pression cristallisés au niveau du manteau. Ils dériveraient d'un magma fortement sous saturé, issu de la fusion partielle d'une lherzolite sous pression d'eau et de gaz carbonique. Lors de sa mise en place, ce magma aurait traversé, à la limite de l'asthénosphère, un liquide de nature carbonatitique, ce qui aurait provoqué la formation de la rushayite.

La nature essentiellement explosive du volcanisme associé serait liée à la chute brutale de solubilité du CO₂ dans le magma lorsque la pression diminue au cours de sa montée vers la surface.
Les minéraux phylliteux dans les gisements hydrothermaux d'uranium. I. Cristallochimie des micas hérités et néoformés
Authors: Leroy Jacques , Cathelineau Michel
Published: December 2019

Several generations of white micas have been recognised in four two-mica granite massifs which are associated with uranium deposits in the Hercynian chain. These different generations correspond to distinct geological phenomena belonging to the deuteric and hydrothermal stages of the history of these massifs.

Crystalchemical studies of these micas with the aid of the electronic microprobe show that each of these phenomena corresponds a phengite of different, well defined compositions. An increase in the phengitic character and a decrease in the paragonite component are observed over time. Strong similarities exist between micas of the same generation belonging to different granite massifs (deuteric micas, episyenitic micas).

The study of the evolution of the earliest deuteric micas during later hydrothermal phenomena, mica episyenitisation and deposition of pitchblende, has shown two opposed trends. In the case of mica episyenitisation, the micas tend to reequilibrate, while in the case of pitchblende deposition and the vein stage in general, the micas preserve their primary character. Several factors may explain this difference in evolution.

Superposition de deux altérations hydrothermales dans la syénite monzonitique du Bac de Montmeyre (Sondage INAG 1, Massif Central, France)
Authors: Meunier Alain
Published: December 2019

L'étude pétrographique du sondage INAG 1 au Bac de Montmeyre (Puy-de-Dôme) a montré l'existence de deux altérations hydrothermales superposées. La roche-mère est une syénite présentant des zones mylonitiques surtout développées dans la partie supérieure du sondage où apparaît une rubéfaction au contact des basaltes sus-jacents.

Une première altération est de nature propylitique et se caractérise par la présence de plusieurs assemblages minéraux stables entre 250 et 280 °C :

— corrensite ± pyrite

— chlorite + épidote riche en fer ± pyrite.

Une seconde altération a déstabilisé les assemblages propylitiques le long de fractures ouvertes et dans la zone rubéfiée de la partie supérieure du sondage. Elle est caractérisée par un assemblage illite˗Mg + beidellite˗K + métavermiculite + oxyde de fer dont la température de cristallisation n'excède pas 100 °C. Les fluides qui provoquent cette déstabilisation ont des activités en oxygène et magnésium très supérieures à celles des fluides propylitiques. Ils ont percolé par gravité dans la syénite sans participer à des circuits convectifs.
Etude expérimentale de la solubilité du chrome dans les bains silicatés basiques et de sa distribution entre liquide et minéraux coexistants : conditions d'existence du spinelle chromifère
Authors: Maurel Colette , Maurel Pierre
Published: December 2019

The solubility of chromium in basic silicate melts was studied experimentally. Runs were carried out at temperatures of 1180-1300°C and oxygen fugacity of 10⁻³ -10⁻⁹ atm, at one atm total pressure. The Cr content of the liquid in equilibrium with chromian spinel increases when temperature increases, and / or when oxygen fugacity decreases, the range of variation being 170-1460 ppm. The partition coefficient D = (Cr₂O₃)sp / (Cr₂O₃)liq, which varies between 257 and 1424, is affected by temperature variations more than by variations of oxygen fugacity.

It is pointed out that variations of temperature and / or oxygen fugacity may induce chromium sursaturation in the melt, and consequently crystallization of spinel. The conditions of coexistence of chromian spinel with clinopyroxene are established.
Associations réactionnelles à amphibole, disthène et grenat dans la métanorite du Bois de Verdus (Aveyron)
Authors: Nicollet Christian
Published: December 2019

Dans le complexe leptyno amphibolique du Lévezou (Aveyron), un ensemble de roches basiques orthodérivées (gabbros, troctolites, norite) est métamorphisé dans les conditions du faciès granulite, donnant des éclogites à omphacite, grenat, amphibole et disthène et des coronites complexes. La norite du Bois de Verdus montre l'assemblage coronitique amphibole + disthène + grenat qui s'est formé vraisemblablement en deux temps : (1) amphibole + disthène s 'accompagnant d'une diminution du pourcentage en anorthite du plagioclase (avec PT = PH₂O ?) ; ainsi les amphibolites à disthène ne sont pas nécessairement le résultat d'un métamorphisme rétrograde affectant les éclogites à disthène ; (2) la formation de grenat s'accompagne vraisemblablement d'une diminution de la pression d'eau. Ce stade à amphibole + plagioclase + grenat + disthène pourrait représenter un stade intermédiaire entre les amphibolites à disthène et les éclogites à disthène et amphibole.

Estudio experimetal del efecto hidrológico de cubiertas verdes para su utilización en el área metropolitana del Gran Resistencia
Authors: Holsbach Néstor , Pilar Jorge , Pilar Claudia
Published: December 2019

Se presentan los resultados preliminares de un estudio sobre modelo físico, referidos a la eficacia y eficiencia hidrológicas de cubiertas verdes para su utilización en el Área Metropolitana del Gran Resistencia (AMGR), Chaco. Las cubiertas verdes de tipo extensivas son sistemas que se colocan sobre techos tradicionales para disminuir los efectos de la impermeabilización del suelo urbano, buscando laminar los hidrogramas de escurrimiento que se generan. Están compuestas por varias capas construidas con distintos elementos, con características y propiedades diferentes, estando la capa superior constituida por un sustrato orgánico, de poco espesor, que permite el crecimiento de vegetación de bajo porte y por el que recibe el nombre de cubiertas verdes. El aumento de la impermeabilización asociada a la creciente urbanización, la baja pendiente natural del terreno y su localización en una zona de riesgo hídrico hacen propicia la implementación de este sistema en las ciudades que conforman el Área Metropolitana del Gran Resistencia como una medida de mitigación que permitiría minimizar los efectos de precipitaciones de elevada intensidad, reduciendo y retardando el agua de escurrimiento directo, colaborando a evitar (o por lo menos minimizar) los anegamientos provocados por las lluvias. En el presente trabajo se buscó evaluar cualitativa y cuantitativamente el efecto de este tipo de techos. Para ello, se construyó un modelo físico de la cubierta extensiva, utilizándose además otra de tipo plana tradicional como contraste. Los resultados preliminares obtenidos mostraron un notorio efecto amortiguador y retardador del escurrimiento de este tipo de cubiertas.

Published: December 2019

Este trabajo da un panorama sobre los desastres asociados a factores naturales y tecnológicos. Se usa la base de datos EM-DAT de la Universidad de Louvain (Bélgica), que cuenta con datos desde el año 1900 hasta el 2018. Los desastres naturales prevalecen sobre los tecnológicos, respecto de la cantidad la relación es 66% a 34%, en cuanto a víctimas fatales los registros indican que el 93.2% está generado por desastres naturales, con relación a la cantidad de afectados la participación de los desastres de origen natural asciende al 99.8% y al considerar las pérdidas materiales los desastres naturales aportan el 99.2%. Además, se obtuvieron los siguientes resultados: a) respecto de la cantidad, los desastres hidrológicos ocupan el primer lugar, con un 38% a nivel mundial, 57% en Sudamérica y 58% en Argentina; b) en cuanto a cantidad de víctimas fatales, a nivel mundial los desastres climatológicos explican el 36%, mientras que en Sudamérica y Argentina son los geofísicos los que generan el 68% y el 87%, respectivamente; c) considerando los afectados, los desastres hidrológicos producen el 48% a nivel mundial y el 95.7% en Argentina, mientras que los climatológicos generan el 47% en Sudamérica; y d) respecto de las pérdidas económicas, en el mundo los desastres meteorológicos aportan el 44%, en Sudamérica los geofísicos generan el 42% y en Argentina los hidrológicos producen el 74%. En Argentina los desastres hidrológicos son los de mayor ocurrencia, los que producen la mayor cantidad de afectados y de pérdidas económicas, no así respecto a víctimas fatales, que contribuyen “solo” con el 8%. Cabe destacar la importancia de las políticas de planificación del uso del recurso hídrico así como también la gestión previa, durante y posterior a la ocurrencia de los desastres hídricos.

El objetivo principal de este trabajo es definir la poesía para primeros lectores y pre-lectores como género literario infantil en el ámbito español. Para ello, hemos establecido un corpus formado por dos colecciones: De la cuna a la luna (Kalandraka) y La cereza (Combel). Mediante una comparación de ambas, estableceremos cuáles son los principales rasgos del género en relación con cuatro aspectos: las dimensiones peritextuales, especialmente el formato y las características materiales; la dimensión textual, con el fin de establecer sus rasgos temáticos y formales; la dimensión visual, para determinar el modo en que la relación entre el texto y la ilustración contribuye al diseño del lector implícito; y, por último, la dimensión epitextual virtual, ya que en ambos casos existen materiales virtuales que proponen experiencias lectoras que van más allá de los propios libros.

Learning disabilities (LD) is turning into a major issue in various nations around the globe which can even contrarily influence human common advancement. The undertaking of this work is to help the specialized programme network in their task to be with the standard. The underlying section of the paper gives a comprehensive investigation of the distinctive components of diagnosing learning disabilities. Despite the fact that LD can be analysed early - before 5 years of age, most youngsters were not determined to have LD until the age of nine on account of its unpredictable side effects and unclear indication in children disorder issue. Fuzzy logic K-means clustering has inspired a tremendous transformation in Machine learning and can take and able to resolve a variation of problems. This paper is the elaboration on the strategy for utilizing this mix to encourage the early analysis of LD. Since Fuzzy Logic clustering in Machine Learning is generally considered and connected in different areas of science, we invite all the related analysts from the fields of computer science, engineering, statistics, social sciences, healthcare, and so on, etc. The result of the paper demonstrates that the previously mentioned methodology can possibly be the potential of the supporting decision-making system in LD investigating and diagnosing.

This paper depicts a novel sub bytes strategy for executing the executing the advanced encryption standard (AES) algorithm that offers a considerably enhanced cryptographic strength. Our strategy depends on composite field math randomization, which involves a low cost of execution while not adjusting the algorithm, does not decrease the recurrence of the work and maintains an ideal similarity to the distributed standard. In this document, we suggest a fast and knowledgeable execution of AES in memory (AIM) to scramble the whole part of the memory only when needed. We use NVM’s intrinsic logic working ability to implement the AES algorithm instead of adding extra processing parts to the cost-sensitive memory. The proposed design is implemented using Modelsim 6.4 C and Xilinx tool Verilog HDL and simulated.

This study evaluated the land use/land cover (LULC) changes in Tuguegarao City and analyzed its impact on Land Surface Temperature (LST). It was carried out using Remote Sensing and Geographic Information System (GIS) techniques. Three Landsat TM and ETM+ images data were acquired for the years 1990, 2005 and 2016 from USGS Earth Explorer portal. ArcGIS software was used to determine the area statistics of the different land cover and to make the final LULC map. LST for the study area was taken from the thermal infrared band of the satellite images by converting the image digital number into degrees Kelvin using the LMin and LMax spectral radiance scaling factors. The largest areal change appeared in the built-up area with an increase of 1120.32 ha. However, this study detected higher LST in the crop land, grassland and barren land areas of the city rather than the built-up parts of the city which does not follow many of previous studies. The results of the study can be presented to the Local Government Unit so that they can draft appropriate laws for the betterment of the city specially that rapid urbanization and uncontrolled population growth may have extreme impact on the environment.

Introducción: la diabetes mellitus es una de las enfermedades crónicas prevenibles con mayor impacto en la población mundial. Objetivo: caracterizar los factores de riesgo de diabetes mellitus tipo 2 mediante la aplicación del test de Findrisk. Materiales y métodos: se realizó un estudio piloto descriptivo que incluyó 51 personas entre 30 y 50 años, residentes en Medellín, Colombia, sin diagnóstico previo de diabetes mellitus. Se aplicó el test de Findrisk para valorar los factores de riesgo asociados a diabetes. Resultados: el 68,6% de las personas fueron mujeres. El 64,7% de la población fue menor de 45 años. El 51,0% de la población obtuvo puntaje menor que 7 (bajo), el 17,6% entre 7 y 11 (elevado levemente), el 21,6% entre 12 y 14 (moderado), el 7,8% mayor que 14 y hasta 20 (alto) y el 2,0% mayor que 20 (muy alto). El promedio del puntaje total fue 7,8. El 51,0% de la población tuvo IMC menor que 25 Kg/m2, el 66,7% no realizaba actividad física diaria, el 47,1% no consumía frutas ni verduras, el 94,1% no tenía antecedentes de niveles de glucosa altos en sangre y el 23,5% presentaba antecedentes familiares de diabetes mellitus en primer grado de consanguinidad. En el análisis de asociación la edad, el consumo de medicamentos antihipertensivos y los antecedentes familiares de diabetes mellitus tuvieron influencia significativa en el puntaje final del test. Conclusiones: el test de Findrisk es una herramienta útil para caracterizar los factores de riesgo de diabetes mellitus tipo 2.
La prueba de esfuerzo electrocardiográfica: utilidad en el diagnóstico y pronóstico de la enfermedad coronaria
Authors: Gallo-Villegas Jaime A. , Aristizábal-Ocampo Dagnovar
Published: December 2019

La prueba de esfuerzo electrocardiográfica evalúa los ajustes fisiológicos en respuesta a un aumento en el metabolismo; además, permite establecer el diagnóstico y pronóstico de diferentes enfermedades cardiovasculares. Esta prueba continúa siendo el método diagnóstico de más fácil acceso y menos costoso para la evaluación inicial de pacientes con síntomas estables, que tienen un riesgo bajo o intermedio de enfermedad coronaria, y en aquellas personas con dolor torácico que consultan al servicio de urgencias. Sin embargo, posee limitaciones en la exactitud diagnóstica, con falsos negativos alrededor del 40% (sensibilidad del 60%) y falsos positivos alrededor del 10% (especificidad del 90%). En este artículo se discute información sobre la prueba de esfuerzo electrocardiográfica, su aplicación tanto para el diagnóstico como el pronóstico y su utilidad en la toma de decisiones en los pacientes en quienes se sospecha o tienen una enfermedad coronaria. Igualmente, se presentan aspectos prácticos para la realización del procedimiento, una propuesta de informe con los principales hallazgos y algunos ejemplos clínicos.
Uso de la terapia combinada en infecciones causadas por enterobacterias resistente a carbapenémicos desde un enfoque microbiológico: revisión sistemática
Authors: Bolaño Ardila Nalleth D.
Published: December 2019

Introducción: las carbapenemasas representan actualmente una amenaza para la salud humana en todo el mundo y constituirán uno de los problemas más difíciles de tratar en los próximos años. Objetivo: describir del uso de la terapia combinada con carbapenémicos en las infecciones por enterobacterias resistente a carbapenémicos desde un enfoque microbiológico. Materiales y Métodos: se realizó una revisión sistemática en PubMed sobre estudios en humanos y modelos de infección múridos, publicados entre 2010 y 2016 en inglés. Los estudios debían reportar los resultados de mortalidad asociada según el esquema de monoterapia y terapia combinada con carbapenémicos. La búsqueda para la selección de los estudios se basó en las palabras clave: “Carbapenem Resistance AND carbapenems”, “treatment and outcomes carbapenems enterobacteriaceae”, “Klebsiella pneumoniae”, “carbapenemase”, “Klebsiella pneumoniae AND combination therapy”. Resultados: se seleccionaron cinco estudios que incluyeron en total 1.313 pacientes con infecciones por enterobacterias resistentes a carbapenémicos y que proporcionaban información sobre el uso de la terapia combinada con carabapenémicos frente a la monoterapia en términos de las tasas de mortalidad asociada. Conclusiones: actualmente no se dispone de estudios clínicos controlados publicados en el tema, por lo que la elección del tratamiento antibiótico frente a las infecciones por enterobacterias resistentes a carbapenémicos aún es controvertida. La evidencia clínica emergente sugiere que el uso de la terapia combinada resulta beneficioso para este tipo de infecciones. Hoy en día los clínicos optan por reutilizar viejos antibióticos como las polimixinas, a pesar de la resistencia codificada por el gen mcr-1 adquirida por plásmidos.
Análise Integrada dos Brejos de Altitude do Nordeste do Brasil a partir de Atributos Fisiográficos / Integrated Analysis of Highland Humid Brejos in Northeast Brazil Based on Physiographic Attributes
Authors: Gois Laís Susana De Souza , Corrêa Antônio Carlos De Barros , Monteiro Kleython De Araújo
Published: December 2019

Brejos de altitude são áreas de exceção climato-edáfico-ecológicas inseridas no domínio semiárido do Nordeste do Brasil, apresentando uma variação paisagística bastante expressiva. Suas peculiaridades mesológicas, quando comparados com o entorno e entre si, têm despertado o interesse de pesquisadores tanto para fins de caracterização quanto de planejamento, uma vez que essas áreas possuem valor ambiental e econômico expressivos no contexto semiárido brasileiro. Neste sentido, o  objetivo desse trabalho é reunir e discutir as principais características fisiográficas já estabelecidas para os brejos de altitude. Foram consultados periódicos, teses,  dissertações, livros e relatórios técnicos que se propuseram a definir e caracterizar os brejos de altitude nordestinos. Ao final, foi possível contabilizar um total de 10 áreas classificadas como enclaves, bem como definir os atributos fisiográficos que as definem. Essas características geraram um quadro síntese que permitiu a realização de uma análise comparativa a partir dos elementos descritivos identificados em cada obra consultada.
PRANATA MANGSA DAN BUDAYA KEARIFAN LINGKUNGAN
Authors: Sobirin Supardiyono
Published: December 2019

Pranata mangsa is a traditional calendar about the rules of the season which has long been known primarily bythe farming community in Java. This calendar is based on pseudo-circulation of the sun, which in the past was a reliableguide for farmers to schedule farming in the rice fields. Along with the progress of civilization of life, understanding of pranata mangsa has faded a lot, among other things because of environmental changes due to population growth, land use change, climate anomalies, and modernization of life. Although pranata mangsa has experienced many deviations, it is assumed that it can still be saved as a very wise and valuable ancestral heritage. One of the benefits is as a cultural aid in preserving the environment, and as a basis for understanding the current season's forecasting technology. A hope that pranata mangsa culture can be revived, namely if the concept of development is carried out on the basis of consistent ecological sustainability, with integrated support in the form of political will, educational will, and cultural will, and integrating traditional wisdom of pranata mangsa with modern technology.

В статье рассматриваются исторические, национальноэтнические, экономические, геополитические и ментальные аспекты формирования социальногуманитарных взаимоотношений населения приграничных регионов Беларуси, Украины и Российской Федерации. Показано, что за время самостоятельного, в пределах суверенных государств, развития, накопились различия в представлении о параметрах межславянского взаимодействия. Вместе с тем, генетическое родство славянских народов, схожие природноклиматические условия, исторический опыт хозяйственного и социогуманитарного взаимодействия, являются надежной базой для поддержания бесконфликтного взаимодействия населения приграничных регионов.

The article discusses the historical, nationalethnic, economic, geopolitical and mental aspects of the formation of social and humanitarian relations between the population of the border regions of Belarus, Ukraine and the Russian Federation. It is shown that during the independent development of sovereign states, differences have accumulated in the idea of the parameters of interSlavic interaction. At the same time, the genetic relation of the Slavic peoples, similar climatic conditions, historical experience of economic and sociohumanitarian interaction, are a reliable basis for maintaining conflictfree interaction between the population of border regions.
