The human right to the name in the Estate of Mexico. A constitutional and conventional approach

This paper analyzes whether the registration of natural persons in the State of Mexico is carried out in strict compliance with the constitutional and conventional principles. For this, it was necessary to study comparatively if said legal act happened subject to the form that the legislation imposed or to the protection of the will of the people, as a consequence of its fundamental right recognized both in the national and international legal order, derived from International Treaties that the Mexican State has signed. The human right to the name, in the State of Mexico, is contemplated for the benefit of the people, although the same legislation is limiting, because to constitute it, the organs of the State have interference, which, we consider, violates the freedom of the people, since that establishes what surnames should be used; act that contains in itself a submission of the people and not the free exercise of their fundamental rights.En este trabajo se analiza si el registro de las personas físicas en el Estado de México se lleva a cabo en estricta observancia a los principios constitucionales y convencionales. Para ello, fue menester estudiar comparativamente si dicho acto jurídico acontecía sujetándose a la forma que impone la legislación o al amparo de la voluntad de las personas, como consecuencia de su derecho fundamental reconocido tanto en el orden jurídico nacional como en el internacional, derivado de los Tratados Internacionales que el Estado Mexicano ha suscrito. El derecho humano al nombre en el Estado de México está contemplado en beneficio de las personas, aunque la misma legislación es limitativa, pues para constituirlo tienen injerencia los órganos del Estado, lo cual, consideramos, vulnera la libertad de las personas, ya que establece qué apellidos deben usarse, acto que encierra en sí mismo una sumisión de las personas y no el ejercicio libre de sus derechos fundamentales

One-Dimensional Modeling of Mechanical and Friction Losses Distribution in a Four-Stroke Internal Combustion Engine

[EN] As the road transport accounts between 15%-18% of worldwide CO2 emissions, the automotive sector has a deep commitment to mitigate global warming. Consequently, stricter regulations have been adopted by the European Union and worldwide to reduce that big impact. Approximately, 10% of the energy generated by fuel combustion in the engine is destined to the auxiliaries components activation and the movement of mechanical elements with relative motion between themselves. A reduction on that figure or alternatively a mechanical efficiency improvement can be directly translated on target alignment. The aim of this work is developing a model to predict the mechanical and friction losses and its distribution in a four-stroke direct injection-diesel engine and simulating different strategies, which increment the engine efficiency. A 1D model has been developed and fitted in GT-SUITE based on the experimental results of a 1.6-L diesel engine. Additionally, a description of the tribological performance has been realized in different parts of the engine where friction is present. Finally, the engine friction maps have been broken down in order to quantify the friction losses produced in the piston ring assembly, crankshaft bearings, and valvetrainTormos, B.; Martín, J.; Blanco-Cavero, D.; Jiménez-Reyes, AJ.

Subacute Drug-Eluting Stent Thrombosis Caused by Stent Underexpansion: Evaluation by Optical Coherence Tomography

We present the case report of a patient presenting with ST segment elevation myocardial infarction due to a subacute drug-eluting stent trombosis within the proximal segment of the left circumflex artery (LCX). Six days before a total chronic occlusion was treated at the mid segment of the LCX by overlapping two drug-eluting stents. Optical coherence tomography (OCT) was helpful to demonstrate stent underexpansion of the overlaping segment as the main mechanism of early stent thrombosis. This case is illustrative about the potential role of OCT to identify the mechanisms of ST and thus guiding the PCI procedure. Moreover, our case shows the capability of the Imagewire to cross a severe stenosis due to stent underexpansion that could not be crossed by the IVUS catheter

Preliminary study on the performance of biomorphic silicon carbide as substrate for diesel particulate filters

This paper presents the results of a preliminary experimental study to assess the performance of biomorphic silicon carbide when used for the abatement of soot particles in the exhaust of Diesel engines. Given its optimal thermal and mechanical properties, silicon carbide is one of the most popular substrates in commercial diesel particulate filters. Biomorphic silicon carbide is known for having, besides, a hierarchical porous microstructure and the possibility of tailoring that microstructure through the selection of a suitable wood precursor. An experimental rig was designed and built to be integrated within an engine test bench that allowed to characterizing small lab-scale biomorphic silicon carbide filter samples. A particle counter was used to measure the particles distribution before and after the samples, while a differential pressure sensor was used to measure their pressure drop during the soot loading process. The experimental campaign yielded promising results: for the flow rate conditions that the measuring devices imposed (1 litre per minute; space velocity = 42,000 L/h), the samples showed initial efficiencies above 80%, pressure drops below 20 mbar, and a low increase in the pressure drop with the soot load which allows to reach almost 100% efficiency with an increase in pressure drop lower than 15%, when the soot load is still less than 0.01 g/L. It shows the potential of this material and the interest for advancing in more complex diesel particle filter designs based on the results of this workMinisterio de Economía y Competitividad (España) MAT2013-41233-R DPI2013-46485-C3-3-RFondos FEDER MAT2013-41233-R DPI2013-46485-C3-3-RUniversidad de Sevilla VI Plan Propio I.3B - C.I. 24/05/2017 MAT2016-76526-

Maximum aerobic speed, maximum oxygen consumption, and running spatiotemporal parameters during an incremental test among middle- and long-distance runners and endurance non-running athletes

[Abstract] Background. Maximal aerobic speed (MAS) is a useful parameter to assess aerobic capacity and estimate training intensity in middle- and long-distance runners. However, whether middle- and long-distance runners reach different levels of MAS compared to other endurance athletes with similar VO˙ 2max has not been previously studied. Therefore, we aimed to compare VO˙ 2max, MAS and spatiotemporal parameters between sub-elite middle- and long-distance runners (n = 6) and endurance non-runners (n = 6). In addition, we aimed to compare the maximal blood lactate concentration [BLa] experienced by participants after conducting these tests. Methods. Telemetric portable respiratory gas analysis, contact and flight time, and stride length and rate were measured using a 5-m contact platform during an incremental test at a synthetic athletics track. VO˙ 2, heart rate, respiratory quotient values in any 15 s average period during the test were measured. [BLa] was analyzed after the test . Running spatiotemporal parameters were recorded at the last two steps of each 400 m lap. A coefficient of variation (%CV) was calculated for each spatiotemporal variable in each participant from 8 km h−1 onwards. Results. Whereas runners reported faster MAS (21.0 vs. 18.2 km h−1 ) than nonrunners (p = 0.0001, ES = 3.0), no differences were found for VO˙ 2max and maximum blood lactate concentration during the running tests (p > 0.05). While significant increases in flight time and stride length and frequency (p < 0.001, 0.52 ≤ η 2 p ≤ 0.8) were observed throughout the tests, decreases in contact time (p < 0.001, η 2 p = 0.9) were reported. Runners displayed a greater %CV (p = 0.015) in stride length than nonrunners. We conclude that middle- and long-distance runners can achieve a faster MAS compared to non-running endurance athletes despite exhibiting a similar VO˙ 2max. This superior performance may be associated to a greater mechanical efficiency. Overall, runners displayed a greater ability to modify stride length to achieve fast speeds, which may be related to a more mechanically efficient pattern of spatiotemporal parameters than non-runners

Prevention of road crashes in older adults: perspectives on facilitators, barriers and the role of the family doctor

This work was supported by the SEMERGEN-UGR Chair of Teaching and Research in Family Medicine (Catedra de Docencia e Investigacion en Medicina de Familia SEMERGEN-UGR), University of Granada, Spain.Background: People over 64 years have a high fatality rate when they are involved in traffic accidents. Besides, older victims of road crashes are expected to rise in the future due to population aging. The purpose of the study was to document their perception on the role of the family doctor, the main facilitating factors, and the perceived barriers to the temporary or permanent restriction of their driving. Methods: This qualitative study used focus group methodology. A sample of 16 people over 65 years old was obtained through a series of segmentation criteria at an active participation centre for older adults in a small town in Jaén province (Spain). All were invited to participate in a discussion during which they were asked to express their opinions and subjective experiences concerning the role of their family doctor. The group conversation was taped, fully transcribed and analysed, and codes were generated with both deductive and inductive methods. Results: After merging the codes to generate themes, we identified 9 relevant categories: perception of age-related risk, road safety, role of public authorities, driver assessment centre, role of the family doctor, role of the family, proposals for addressing traffic accidents in older adults, consequences of the driving prohibition, and public transport. All categories help to explain the subjective driving and traffic safety experiences of older road users. Conclusions: Although family doctors do not usually ask their older patients about road driving, they are highly valued by these patients. Thus, family doctors have a great potential to act, along with the family members, for the benefit of older patients’ traffic safety, in ways that can prevent their involvement in road crashes and reduce the negative consequences of having to stop driving if necessary.SEMERGEN-UGR Chair of Teaching and Research in Family Medicine (Catedra de Docencia e Investigacion en Medicina de Familia SEMERGEN-UGR), University of Granada, Spai
