Efectos de la normativa en materia preventiva sobre los daños para la salud de los trabajadores "El caso del sector de la construcción español"
Authors: Simal Carretero Eduardo 
Published: May 2022

El análisis del número de accidentes de trabajo y enfermedades profesionales aparecidos anualmente en el sector de la construcción español en relación con el número de trabajadores ocupados en dicho sector revela una dependencia estadísticamente significativa entre indicadores, de forma que un aumento en la actividad económica del sector se traduce invariablemente en un aumento en la siniestralidad y en el número de casos de enfermedades profesionales. La dependencia encontrada pone de manifiesto el fracaso de las políticas preventivas introducidas hasta la fecha por el legislador que, si bien consiguen un descenso en la siniestralidad del sector, no consiguen eliminar la relación directa entre ocupación y daños para la salud, estando en el origen una interpretación laxa por parte de empresarios y trabajadores del contenido de las leyes de prevención de riesgos laborales, entendiéndose éstas más como una obligación que cumplir para evitar sanciones y conseguir acceder a las obras que como una actitud proactiva necesaria para evitar accidentes de trabajo y enfermedades profesionales. Las organizaciones deben cambiar su punto de vista meramente economicista hacía posturas más comprometidas, a todos los niveles, con la seguridad y salud en el trabajo.
Nota de leditor. Respetado lector, recuerde que, el desarrollo de esta ponencia ocurrió bajo el contexto español, es por ello que, su contenido y legislación se aprecia en el marco europeo.

Published: May 2022

Objective: The purpose of this study was to observe the imaging characteristics of the COVID-19 pneumonia and extent of pulmonary involvement in COVID-19 with quantitative computed tomography (CT) and to assess of disease burden on.
Material and Methods: Patients were retrospectively enrolled in the study from March 20 to April 20, 2020. All patients underwent real-time reverse transcription–polymerase chain reaction (RT-PCR) testing. Two hundred and fifty seven patients (mean age 50 years; range 18-91years) with positive PCR and CT
findings were included in the study. Lung computed tomography findings and involvement rates of all patients were determined. Nonparametric statistical tests
were used to examine the relationship between the involvement ratio of lung disease and the age or sex.
Results: Two hundred and fifty seven patients (147 males and 110 females) with SARS-CoV-2 infection were enrolled. The high density lung volume was significantly higher in males than in females. A significant correlation was observed in high-density lung volume between the genders in the 40-69 age group and the involvement was higher in males. The high density lung percentage was higher in the group above 80 years old.
Conclusion: As a result, we found that among the age groups in our study, the percentage of lung involvement was higher in the group above 80 years old. Our results may help to identify the highest-risk patients and those who require specific treatment strategies

Las implementaciones de diseños educativos son una actividad que se lleva a cabo a partir del segundo semestre a través de los cursos de la línea pedagógica en las carreras de licenciaturas de la Universidad Icesi. Por ello, cuando al inicio del semestre 2021 - 2 la profesora Maristela Cardona nos contó que la práctica para el semestre en su asignatura, Diseño de ambientes de aprendizaje III, era en la Institución Educativa Técnica Industrial Pedro Antonio Molina Sede Vencedores no nos imaginábamos todo lo que aprenderíamos. A continuación, contaremos el proceso y los aprendizajes que adquirimos. El grupo seleccionado para las prácticas, que se llevaron a cabo en un mes, fue Caminar I que se compone de chicas y chicos con condición de extraedad [1] que ven contenidos curriculares de sexto y séptimo grado de bachillerato. La misión que nos propusieron las directivas era la de dar las clases de ética, español, inglés, sociales y artes. Lo llevamos a cabo en parejas, es decir, que en cada área interactuaban con mínimo dos profes y máximo cuatro al tiempo, dado que nos solíamos acompañar entre parejas.

[1] La extraedad es el desfase entre la edad y el grado y ocurre cuando un niño o joven tiene dos o tres años más por encima de la edad promedio para cursar un determinado grado. Además, la Ley General de Educación plantea que la educación es obligatoria entre los 5 y 15 años de edad, es decir, de transición a noveno grado; y que preescolar es obligatorio y lo cursan niñas y niños entre 5 y 6 años de edad.

Case study on the usefulness of an instrumented constant brake for the evaluation of the propulsive force of the fins in lifesavers.
Authors: Carballo López Javier , García Silva Antía , García García Óscar 
Published: May 2022

Background: Assessing physical performance is essential to improve planning and training processes. This assessment is essential in lifesaving, both in its sporting and professional aspects.
Objectives: The objective of this study is to explore the suitability of a propulsive force measurement test battery and the usefulness of an experimental power test in lifesaving that yields data on force, power and technique.
Method: A world-class athlete has participated in this project. The same battery of tests has been carried out at three times of the season. The tests correspond to the maximum propulsive force test, the average propulsive force test and the experimental power test.
Results: The maximum propulsive force (299.75 N - 332.13 N) has improved throughout the season, as well as the mean propulsive force (94.26 N - 94.96 N) and power (25.21 - 37 .59w). Also other parameters such as kick amplitude (164.66 N ± 29.31 - 228.10 N ± 20.07) have increased, while frequency (1.6 Hz - 1.2 Hz) has decreased throughout the season.
Conclusions: The tests carried out provide relevant information and they are correlated with each other. The maximum propulsive force test and the experimental power test could provide the most relevant information to prescribe subsequent training.
Robust Optimization Technique Using Modified Net Present Value and Stochastic Simplex Approximate Gradient
Authors: Fortaleza Eugenio L. F. , Sanchez William Humberto Cuellar , Neto Emanuel Pereira Barroso , Miranda Marco Emilio Rodrigues , Munerato Fernando Perin 
Published: May 2022

Summary
This article aims to combine, from previous works, a modified objective function and the stochastic simplex approximate gradient (StoSAG) to provide a robust technique that optimizes reservoir production on the basis of a sequence of short-term optimizations. Usually, in reservoir optimization, the main goal is to maximize the net present value (NPV); this work used a modified NPV (MNPV) function that introduces reservoir parameters into the objective function. This MNPV analyzes the relation between cash flow and the reduction of the produced oil fraction, which is an indicator of the reduction of the well production life. On the other hand, the StoSAG is a well-established algorithm for robust optimization, and it was used to perform a constructive optimization with the MNPV cost function. The proposed technique (MNPV), together with StoSAG, is compared with other techniques from the literature using a regular base of all reservoir life cycle and the same proposed short-term optimizations, but using the classical NPV. These comparisons were made based on two benchmarks, SPE9 and Egg reservoir models, with an ensemble of 5 and 100 realizations, respectively. As a result, the MNPV StoSAG presents strong cash flow at the beginning of the reservoir production, a competitive NPV along the entire life cycle, and fast simulation time.
Design of Steam Alternating Solvent Process Operational Parameters Considering Shale Heterogeneity
Authors: Ma Zhiwei , Coimbra Luis , Leung Juliana Y. 
Published: May 2022

Summary
The steam alternating solvent (SAS) process involves multiple cycles of steam and solvent (e.g., propane) injected into a horizontal well pair to produce heavy oil. These solvent-based methods entail a smaller environmental footprint with reduced water usage and greenhouse gas emissions. However, the lack of understanding regarding the influences of reservoir heterogeneities, such as shale barriers, remains a significant risk for field-scale predictions. Additionally, the proper design of the process is challenging because of the uncertain heterogeneity distribution and optimization of multiple conflicting objectives. This work develops a novel hybrid multiobjective optimization (MOO) workflow to search a set of Pareto-optimal operational parameters for the SAS process in heterogeneous reservoirs.
A set of synthetic homogeneous 2D is constructed using data representative of the Cold Lake reservoir. Next, multiple heterogeneous models (realizations) are built to incorporate complex shale heterogeneities. The resultant set of SAS heterogeneous models is subjected to flow simulation. A detailed sensitivity analysis examines the impacts of shale barriers on SAS production. It is used to formulate a set of operational/decision parameters (i.e., solvent concentration and duration of solvent injection cycles) and the objective functions (cumulative steam/oil ratio and propane retention). The nondominated sorting genetic algorithm II (NSGA-II) is applied to search for the optimal decision parameters. Different formulations of an aggregated objective function, including average, minimum, and maximum, are used to capture the variability in objectives among the multiple realizations of the reservoir model. Finally, several proxy models are included in the hybrid workflow to evaluate the defined objective functions to reduce the computational cost.
Results of the optimization workflow reveal that both the solvent concentration and duration of the solvent injection in the early cycles have significant impacts. It is recommended to inject solvent for longer periods during both the early and late SAS stages. It is also noted that cases with higher objective function values are observed with more heterogeneities. This work offers promising potential to derisk solvent-based technologies for heavy oil recovery by facilitating more robust field-scale decision-making.
On the Injectivity of an Integral Operator Connected to Riemann Hypothesis
Authors: Adam Dumitru 
Published: May 2022

Abstract
The equivalent formulation of the Riemann Hypothesis (RH) givenby Alcantara-Bode ([2], 1993) states: RH holds if and only if the inte-gral operator on the Hilbert space L2(0,1) having the kernel functiondefined by the fractional part of (y/x) is injective. This formulationreduced one of the most important unsolved problems in pure math-ematics to a problem whose investigation could be made by standardtechniques of the applied mathematics.The method introduced to deal with, is based on a result obtainedin this paper: an operator linear, bounded, Hermitian on a separableHilbert space that is strict positive on a dense family of includingsubspaces, on which the sequence of the ratios between the smallestand largest eigenvalues of the operator restrictions on the family isbounded inferior by a strict positive constant, is injective.Using a version for integral operators on L2(0,1) we proved theinjectivity of the integral operator in the equivalent formulation of theRH given in [2].

Abstract
Background: Repetitive transcranial magnetic stimulation (rTMS), as a non-invasive brain stimulation technique, has shown potentials for consciousness recovery of patients with disorders of consciousness (DoC), as it is effective in regulating the excitability of central nervous system. However it is difficult to achieve satisfactory effect with “one size fits all” rTMS treatment due to different clinical conditions of patients. There is an urgent need to develop individualized strategy to improve the effectiveness rTMS on patients with DoC.Methods: Our protocol is a randomized double-blind sham-controlled crossover trial that includes 30 DoC patients. Each patient will received 20 sessions, in which 10 sessions will be rTMS-active stimulus and the other 10 sessions will be sham stimulus, separated by no less than 10 days’ washout period. The rTMS-active will include 10 Hz rTMS over the individualized-targeted selection area for each patient according to the different insult regions of the brain. Coma Recovery Scale-Revised (CRS-R) will be used as primary outcome at baseline, after the first stage of stimulation, at the end of the washout period and after the second stage of stimulation. Secondary outcomes will be measured at the same time, including efficiency, relative spectral power and functional connectivity of high-density electroencephalo-graph (EEG). Adverse events will be recorded during the study.Discussion: rTMS has obtained Grade A evidence in treating patients with several central nervous system diseases, and there has been some evidence showing partial improvement on level of consciousness in DoC patients. However, the effectiveness of rTMS in DoC is only 30%~36%, mostly due to the non-specific target selection. In this protocol, we present a double-blind crossover randomized sham-controlled trial based on the individualized-targeted selection strategy that aims to study the effectiveness of rTMS therapy for DoC, and the result may provide new insights to non-invasive brain stimulation.Trial registration: ClinicalTrials.gov: NCT05187000.

The impact of economic agglomeration on technological level and carbon dioxide emission intensity: A spatial perspective based on China's province-level data
Authors: Chen Hongmin , Luo Tianyu 
Published: May 2022

Abstract
Based on the data of 30 provinces in China from 1995 to 2019, this paper combines dynamic spatial Durbin model, and intermediary effect model to explore the spatial influence mechanism between economic agglomeration, technological level, and carbon emission intensity. Firstly, there is a significant inverted N-curve relationship between economic agglomeration and carbon emission intensity. Secondly, economic agglomeration has a direct and indirect dual effect on carbon intensity, in which technology level as an intermediary variable indirectly affects carbon emission intensity. Finally, in the time dimension, the concentration of carbon intensity of 30 provinces has increased. In the spatial dimension, economic agglomeration and technological progress can effectively constrain the level of carbon intensity, but to a certain extent it will increase the level of carbon intensity in surrounding areas.
