Las malformaciones vasculares representan un heterogéneo espectro de lesiones que suelen presentarse como un reto diagnóstico y terapéutico, por lo cual se requiere de un alto índice de sospecha clínica para llegar al diagnóstico definitivo. El síndrome Cloves es un trastorno de sobrecrecimiento poco común y de etiología genética asociada a una mutación somática activadora de PIK3CA, que forma parte de la vía de señalización intracelular PI3K-Akt-mTOR. Clínicamente, se caracteriza por un sobrecrecimiento lipomatoso congénito de cualquier parte del cuerpo (principalmente el tórax), acompañado de malformaciones vasculares y linfáticas, nevus epidermal y anomalías estructurales del sistema óseo como escoliosis y alteraciones de la columna vertebral. Actualmente el pilar terapéutico de este síndrome es la terapia con rapamicina, un inhibidor de la vía mTOR. Por su parte, el síndrome de Klippel-Trenaunay, de igual manera, es una afección vascular compleja asociada al sobrecrecimiento, resultado de mutaciones somáticas en el gen PIK3CA con presencia de traslocaciones cromosómicas y alteraciones en el gen vascular VG5Q. Como características clínicas, posee una tríada clásica compuesta por hemihipertrofia de los tejidos blandos y los huesos de una extremidad, hemangiomas cutáneos y várices en posiciones anatómicamente anormales. Las principales características distintivas de este síndrome residen en la presencia de anomalías vasculares de tipo lento, desprovistas de fístulas arteriovenosas significativas, en comparación con el síndrome Cloves. En ambos casos, la presencia de características clínicas coincidentes relacionadas con los síndromes de sobrecrecimiento con alteraciones en el gen PIK3CA pone en manifiesto el reto de un diagnóstico certero.

This article outlines a model of proportionality analysis for the adjudication of positive constitutional economic and social rights. This model is the key for answering three questions: (i) First, to what extent constitutional courts hold the power to determine the substantive content of positive constitutional economic and social rights when the right- holders claim that their addressees have violated those rights by failing to comply with what they require? (ii) Second, how constitutional courts should ground the determination of that substantive content? (iii) Third, how constitutional courts should choose appropriate remedies when they have established a violation of one of those rights? Three distinctions are the basis of the above-mentioned proportionality model, namely, the differences: (i) between empirical and normative aspects of the adjudication of positive constitutional economic and social rights; (ii) between the level and mode of fulfillment of those rights; and (iii) between the competence of political authorities and courts to determine the appropriate level and mode of satisfaction. Using some elements of Wittgenstein methodology of family resemblance, this article adjusts the structure of proportionality analysis, which courts apply to adjudicate freedoms, and incorporates elements drawn from those three distinctions. The outcome is an analysis suitable for the specificities of the adjudication of positive economic and social rights. [ABSTRACT FROM AUTHOR]

Orange processing and wood production industries generate wastes in the form of orange peel and eucalyptus leaves. These residues can be valorized as feedstocks to produce essential oils. Therefore, a simultaneous orange peel and eucalyptus leaves essential oil extraction process integrating solar energy was simulated. Biomass and essential oils were simulated by using equivalence models. The coupling of solar collectors allowed the extraction of eucalyptus essential oil, with a saving of 10 % in the total energy load. [ABSTRACT FROM AUTHOR]

International investment law faces five core legitimacy challenges: the state-dependency challenge, the human and constitutional rights challenge, the equality challenge, the standard of protection challenge, and the investor state dispute settlement system challenge. This Article endorses the claim that constitutional courts can contribute to the solution of those legitimacy challenges when they exercise the power to review the constitutionality of international investment treaties. From a transformative perspective, constitutional courts of host states can: (i) create public deliberation and raise awareness concerning the legitimacy challenges of international investment law; (ii) grant equal treatment to national and foreign investors; (iii) require governments to negotiate balanced and less open-textured provisions in international investment treaties; (iv) safeguard the protection of human and constitutional rights, and other common goods; and (v) raise due process, predictability, transparency, and proportionality standards concerning the investor state dispute settlement system. These judicial undertakings can strengthen the bargaining power of host executive branch authorities in the negotiation of international investment treaties and can narrow down the space of discretion of international investment arbitral tribunals. Both outcomes could render international investment treatises' creation and enforcement more legitimate. [ABSTRACT FROM AUTHOR]

This study examined the function of instructional objectives considered as stimuli events for students during instructional episodes. Its purpose was to explore the effect of presenting different instructional objectives for the same didactic discourse on the learning of contextual identification competences. Twenty six college students were distributed randomly in three groups, two of which received different pre-reading instructional objectives prescribing them to identify distinctive criteria in the same text. A third group did not receive any instructional objective. Results found in identification tasks did not show statistically significant differences between the three groups, even though the best performances were related to the criterion prescribed in the instructional objective. The authors conclude on the need to analyze the stimulus function of instructional objectives in terms of its interaction with individual participants

Introduction: It is necessary to increase the quality and production of R3, the main material for the production of dielectric oil at the Sergio Soto Oil Refinery, which may be affected by the availability of raw materials. Objective: To evaluate the alternative of mixing national crude, specifically that of the Pina-Cristales field, with Russian Ural oil. Materials and Methods: Three blends of different oils were analyzed using the Aspen Hysys simulator (Pina-Cristales and Ural, of the latter three varieties that are entering the country), which are evaluated by varying the ratios between them to 7 in different proportions (95:5, 90:10,85:15,80:20,70:30,60:40 and 50:50). With a view to minimizing the import of Ural, the experimental analysis was carried out with a higher proportion of Cuban oil. Results and Discussion: The adjustment of the experimental results reported for the three samples yielded that a mixture Pina + UralsexLuga in a ratio of 60 and 40% respectively, with R3 acidity values of 1.5 %, yield of 10% and a total amount of R3 cut of 4 166.66 kg/h is the most recommendable. For its introduction on an industrial scale, a cost-benefit economic analysis was carried out and the optimal composition of the selected mixture was selected through the derivation of the adjusted regression model. Conclusions: For a composition of 62.34% Pina and 38.64% Ural, a maximum profit of 1 896 220.36 USD/year was achieved. [ABSTRACT FROM AUTHOR]

Antecedents. Communication skills are critical to establish effective medical interactions, so the importance of teaching them while training of health professionals has become evident. Objective. The present study aimed to analyze the effect of a psycho-educational workshop for medical stu-dents, emphasizing the development of communication skills at five stages of regular medical interviews. Method. Data collected included participants' performance while interviewing simulated patients and writing what they would do with hypothetical cases. The study involved 17 GP-level program medical students in their fourth semester, 12 acted as simulated patients, and nine as supervisors. Participants completed three phases: pretest, treatment, and post-test. The initial and final phases involved applying two tests: Declarative and Active. Results. The largest gain scores occurred for treatment planning and closing stages, followed by general skills. The gain scores obtained in each group of skills in terms of being referred from the workshop contents, and being carried out, showed noticeable consistence. Discussion. Results suggest that teaching communicative skills can improve physicians' interaction with their patients and the care they provide. [ABSTRACT FROM AUTHOR]

A piezoelectric energy harvester generator is a device capable of transforming environmental mechanical energy into electrical energy. The piezoelectric electromechanical parameters determine the maximum electrical power which is able to be transferred to an electric load. In this research work, an exhaustive study of the electromechanical parameters related to the piezoelectric material is carried out, modeling them as components of an electrical circuit, in order to analyze their influence on the transmitted power. On the other hand, some electrical loads are simulated to determine different matrix scenarios for a model developed by state-space equations in the Laplace transform domain. The results obtained have allowed to know how the piezoelectric material properties and mechanical characteristics influence the electrical power output of the energy harvester generator and the energy transmission behavior for different electric loads. The conclusions show how the different electromechanical parameters are related to each other, and how their combination transforms the mechanical environmental energy into the required electrical energy. The novelty of this research is the presentation of a model capable of obtaining the optimized working point of the harvester, taking into account not only the electric loads and current demands but also the piezoelectric material parameters.

A ridesharing system is a transport mode where two or more users share the same vehicle and divide the trip's expenses based on similar routes and itineraries. Popular ridesharing systems, such as Uber, Flinc, and Lyft, define a matching among users based only on the coincidence of routes. However, these systems do not guarantee a stable matching (i.e., a matching in which no user prefers another different from the assigned one). In this work, a new ridesharing system model is proposed, including three types of trips: identical, inclusive, and partial. This model is used to introduce a new algorithm to address the stable matching problem for ridesharing systems. Finally, a set of experimental simulations of the proposed algorithm is conducted. Experimental results show that the proposed algorithm always produces a stable matching. [ABSTRACT FROM AUTHOR]

This article presents a novel control strategy for a dual active bridge series resonant converter. The strategy seeks to ensure the stability of the converter over its entire dynamic range while enhances the transient response. Both properties allow the use of the converter in new applications, where fast dynamics are required, surpassing the performance of existing feedback loops. Starting from the generalized averaged model of the converter, we propose a nonlinear control strategy by means of Lyapunov's stability theory. After that, we derive a series of modifications in order to implement the strategy in a microcontroller or a DSP, including a sensorless method to tackle the lack of measurements of certain variables and an adaptive control law to deal with uncertain parameters in the model. The strategy is evaluated in simulations and experiments, employing a commercial converter, and comparing the results with other control policies. [ABSTRACT FROM AUTHOR]

Piezoelectric harvesters use the actuation potential of the piezoelectric material to transform mechanical and vibrational energies into electrical power, scavenging energy from their environment. Few research has been focused on the development and understanding of the piezoelectric harvesters from the material themselves and the real piezoelectric and mechanical properties of the harvester. In the present work, the authors propose a behavior real model based on the experimentally measured electromechanical parameters of a homemade PZT bimorph harvester with the aim to predict its Vrms output. To adjust the harvester behavior, an iterative customized algorithm has been developed in order to adapt the electromechanical coupling coefficient, finding the relationship between the harvester actuator and generator behavior. It has been demonstrated that the harvester adapts its elongation and its piezoelectric coefficients combining the effect of the applied mechanical strain and the electrical behavior as a more realistic behavior due to the electromechanical nature of the material. The complex rms voltage output of the homemade bimorph harvester in the frequency domain has been successfully reproduced by the proposed model. The Behavior Real Model, BRM, developed could become a powerful tool for the design and manufacturing of a piezoelectric harvester based on its customized dimensions, configuration, and the piezoelectric properties of the smart materials.

Since its beginning the 1980s, the globalized model of economic development in Mexico has generated paradoxical results. On the positive side, Mexico attained a privileged position among the mayor economies of the world by becoming the 13th largest exporter and the 12th main importer, while simultaneously turning into a high-ranking recipient of foreign direct investment. These positive results deeply diverge with the mediocre performance in economic growth and the high levels of unemployment, informality and poverty. In this paper we argue that these paradoxical results are the consequence of structural disequilibrium caused by the reorientation of production towards export-based global value chains, which did not contribute to the development of an integrated industrial sector with forward and backward linkages between foreign and local firms. The flows of trade and investment that were stimulated by the North American Free Trade Agreement (nafta) did not promote economic growth in Mexico because of structural weaknesses that derived from an exporting sector where foreign firms limited the value-added produced by local firms, and created an inelastic supply of imported inputs. Hence, the export-led model became a development strategy that weakened the capacity for the consolidation of a strong and dynamic internal market. [ABSTRACT FROM AUTHOR]

The operation of an interior permanent magnet synchronous motor included in an electric power steering system is related to two demanding requirements: (i) the low‐voltage DC source pushes the motor to a deep flux weakening region, and (ii) the motor is so optimised that it can withstand only few cycles at nominal torque. Owing to that, maximum torque per ampere (MTPA) and maximum torque per volt (MTPV) current reference generation strategies are common in this type of application. Most of the published MTPA or MTPV strategies are applied to standard voltage motors, so stator resistance is typically neglected, leading to simpler equations. Other works consider the stator resistance but, as the resulting equations are complex, look‐up tables or numerically adjusted polynomials are employed in current generation tasks. This work presents analytical expressions allowing the exact computing of current references. These expressions include stator resistances. The battery voltage is considered as an input variable, together with motor speed and reference torque, and direct and quadrature current references are the output variables. Contrary to look‐up tables or numerically adjusted polynomials, the proposed expressions can take into account any parameter variation during real‐time operation. Simulation and experimental results validate the proposed approach. [ABSTRACT FROM AUTHOR]

This paper aims to analyze the involved variables in training evaluation through an extensive analysis of the different methodologies or models used in training evaluation and the characterization of all the involved elements during knowledge transfer by training process. It also provides an approach to the solution of evaluation problems through the integration of tools to create custom-made models for each organizational need. 35 training evaluation models and methodologies were identified in the literature. The most popular type of evaluation is the summative evaluation with 60%, followed by the confirmative evaluation with 43%, and formative evaluation with 29%. In combination, 40% of the proposals consider a summative-confirmative evaluation and 26% consider a summative-formative combination. The most popular tool to evaluate training courses is the questionnaire with 57%, followed by interviews with 31%. Additionally, it was found that there are very few integrative training evaluation methodological proposals. [ABSTRACT FROM AUTHOR]

The optimization of the battery pack in an off-grid Photovoltaic application must consider the minimum sizing that assures the availability of the system under the worst environmental conditions. Thus, it is necessary to predict the evolution of the state of charge of the battery under incomplete daily charging and discharging processes and fluctuating temperatures over day-night cycles. Much of previous development work has been carried out in order to model the short term evolution of battery variables. Many works focus on the on-line parameter estimation of available charge, using standard or advanced estimators, but they are not focused on the development of a model with predictive capabilities. Moreover, normally stable environmental conditions and standard charge-discharge patterns are considered. As the actual cycle-patterns differ from the manufacturer's tests, batteries fail to perform as expected. This paper proposes a novel methodology to model these issues, with predictive capabilities to estimate the remaining charge in a battery after several solar cycles. A new non-linear state space model is proposed as a basis, and the methodology to feed and train the model is introduced. The new methodology is validated using experimental data, providing only 5% of error at higher temperatures than the nominal one. [ABSTRACT FROM AUTHOR]

Legal implementation has always been a challenge in Bangladesh. The Right to Information Act 2009 (the RTI Act) was introduced in Bangladesh with the objective of ensuring people’s access to government information for improving accountability and empowering people to participate in decisions that shape the social, economic, and political aspects of their lives. However, this article suggests that there has been no significant improvement in accessing government information despite the enactment and the strategies for the implementation of the RTI Act. Most citizens are unaware of their legal entitlements to seek and receive information. Only a small number of applications have been registered with public offices since the RTI Act was introduced in 2009. The article argues that one of the main reasons behind the lack of improvement is that the chosen implementation approach fails to engage the public to exercise their right to access information related to government services. This article claims that a proactive and deliberative approach to information disclosure is a much better alternative to the current scheme for implementing the RTI Act. [ABSTRACT FROM AUTHOR]
