Authors: Ares Sofía Estela , Auer Alejandra Denise , Mikkelsen Claudia Andrea 
Published: June 2023

El objetivo del artículo es analizar la calidad de vida objetiva de los habitantes de los distritos de la provincia de Buenos Aires (Argentina), exceptuando los partidos del Gran Buenos Aires (GBA), y explicar las diferenciaciones territoriales a partir de dos variables como el Producto Bruto Geográfico (PBG) per cápita (2003) y la Tasa anual de crecimiento intercensal (2001-2010). Se aplicó una metodología de naturaleza cuantitativa, basada en la obtención de indicadores a partir de fuentes de datos secundarias. En primer lugar, se construyó el índice de calidad de vida con indicadores que integran las dimensiones Educación y Empleo, Saneamiento y Vivienda, Comunicación y Conectividad (TICS), y Ambiente. En segunda instancia, se evaluó la asociación estadística entre el indicador sintético de calidad de vida y dos indicadores, uno de naturaleza económica como el PBG (2003) y el otro de orden demográfico, la tasa de crecimiento anual intercensal para el periodo 2001-2010. Los resultados evidencian la presencia de desigualdades territoriales en referencia a la calidad de vida de la población y el potencial explicativo de las variables independientes propuestas.

Abstract
Occupational and environmental toxicology specialists find catecholamine fluctuations in brain tissue relevant for research of neurotoxicity, such as that induced by manganese or zinc, pesticides, industrial solvents, plastic, air pollution, or irradiation. Considering that catecholamine tissue concentrations are generally very low, their extraction requires a reliable and optimal method that will achieve maximum recovery and minimise other interferences. This study aimed to evaluate whether the aluminium (III) oxide (Al2O3, alumina) based cartridges designed for catecholamine isolation from plasma could be used for solid-phase extraction (SPE) of catecholamine from the brain tissue. To do that, we homogenised Wistar rat brain tissue with perchloric acid and compared three extraction techniques: SPE, the routine filtration through a 0.22 µm membrane filter, and their combination. In the extracts, we compared relative chromatographic catecholamine mobility measured with high performance liquid chromatography with electrochemical detection. Chromatographic patterns for norepinephrine and epinephrine were similar regardless of the extraction technique, which indicates that the alumina cartridge is good enough to isolate them from brain tissue. However, the dopamine pattern was unsatisfactory, and further experiments are needed to identify the issue and optimise the protocol.
Estimating flavonoid oxidation potentials: mechanisms and charge-related regression models
Authors: Miličević Ante 
Published: June 2023

Abstract
In this paper, I tested our quadratic regression models for the estimation of flavonoid oxidation potentials based on spin populations, the differences in the net atomic charges between a cation and a neutral flavonoid, between a radical and an anion of a flavonoid, and between a radical and a neutral flavonoid on a larger set of flavonoids (N = 35). By including six new flavonoids (5,6,7-trihydroxyflavone, 3,3’,4’,7-tetrahydroxyflavone, 3,7-dihydroxyflavone, 4’,7-dihydroxyflavone, 4’,5,7-trihydroxyisoflavone, and 6-hydroxyflavone), we created a respectable calibration set of 35 flavonoids with their oxidation potentials all measured at the same conditions by the same experimentalist. The best model was based on the mean values of the three variables using differences in the net atomic charges (R
2 = 0.970, S.E. = 0.043), which are connected with the three different mechanisms of electrochemical oxidation, SET-PT, SPLET, and HAT.

Published: June 2023

To interpret the provenance 0f Injana Formation, 20 sandstone samples of Injana Formation were collected from Zawita and Dekala areas north Iraq (10 for each sections ), then thin section have been done sildes. The petrographic study showed that the sedimentary, metamorphic and igneous rock fragments, quartz (mono&polycrystalline) and feldspars (microcline, orthoclase and plagioclase) make up the main grain components of the sandstone. Carbonate cement is more common cementing minerals, and the matrix is subordinate. The percentage of mono-quartz and sedimentary, igneous rock fragments are greater than the amounts of feldspar and poly-quartzand metamorphic fragments. A diagenetic processes were represented by the carbonate, iron oxides and evaporite cements, as well as compaction, cementation, and dissolution. The majority of the rocks of Injana Formation’s provenances are sedimentary and igneous, with minor amounts of subordinate metamorphic rocks. These sandstones are considered to be immature and classified as immature Litharenites type. The tectonic provenances that are extrapolated from petrographical results are transitional and lithic with effect of uplifting of Alpaine oroging recycled origin which are derived from the order rocks during the Miocene age.
Lagrangian Simulation Methodology for Large-Eddy Simulations of Prefilming Air-Blast Injectors

Published: June 2023

A Lagrangian framework is proposed to address liquid film and atomization modeling in large-eddy simulations (LESs) of aeronautical air-blast injectors. The Lagrangian liquid film model of O’Rourke and Amsden (“A Spray/Wall Interaction Submodel for the KIVA-3 Wall Film Model,” SAE International TP 2000-01-0271, Warrendale, PA, 2000) is improved by introducing a subgrid contact angle to better predict the film height and the resulting film dynamics. Next, the phenomenological the primary atomization model for prefilming air-blast injectors (PAMELA) proposed by Chaussonnet et al. (“A New Phenomenological Model to Predict Drop Size Distribution in Large-Eddy Simulations of Airblast Atomizers,” International Journal of Multiphase Flow, Vol. 80, April 2016, pp. 29–42) for primary atomization at the prefilmer edge is enhanced to deal with complex geometries. This model is able to predict the droplet-size probability density function from the prefilmer height and flow conditions. The original formulation relied on correlations valid for flat plates to determine the gas boundary-layer thickness, and it required a gas velocity at film height to be set by the user. These two points make its use difficult for complex configurations where there is no simple correlation for the gas boundary-layer thickness and the gas velocity at film height cannot be a priori estimated. An embedded methodology, named the automatic PAMELA, is therefore proposed in this work to automatically determine these two quantities in the simulation. For each cell of the prefilmer edge where atomization occurs, the gas boundary-layer thickness is estimated by analyzing the local velocity profile thanks to Lagrangian probes; and the gas velocity is computed from the local film height by assuming a logarithmic velocity profile. Finally, the film and primary atomization models are coupled to a secondary atomization model, and they are assessed on an industrial air-blast aeronautical injector. The average droplet velocity profiles and Sauter mean diameters are compared against experimental phase Doppler particle analyzer measurements, and they demonstrate the ability of the proposed framework to perform Lagrangian LESs of liquid injection in complex geometries.

Authors: Byalovsky Yu. Yu. , Rakitina I. S. 
Published: June 2023

Background. In various situations healthy people may experience breathlessness caused by high altitude, breath-holding, anxiety or panic driven by stressful events, and, very often by physical activity. However, variability in perception of dyspnea in healthy individuals is yet to be explored. The present study analyzes the variability of dyspnea perception in healthy people in the context of additional respiratory resistance.Objective — to assess the variability in perception of dyspnea in healthy individuals against a step-up increase in additional respiratory resistance, and to evaluate the relationship between dyspnea perception and physical activity levels.Methods. A cross-sectional observational exploratory study involved healthy individuals aged 19–25. The study was conducted at the Department of Pathophysiology, Ryazan State Medical University named after acad. I.P. Pavlov (Russia), in the period from November 2018 to June 2019. A total number of individuals under study comprised 42. Study participants were subjected to additional respiratory resistance, when dyspnea perception was estimated using a modified Borg scale. Then all participants were divided into three groups according to the tertiles in their perception: slight perception (Borg score < 2; n = 13), moderate perception (Borg score 2–5; n = 19) and high perception (Borg score > 5, n = 13). The study involved determination of body mass index, maximal airway pressure, pulmonary function, physical activity by means of IPAQ (International Physical Activity Questionnaire) and 6MWT (6 Minute Walking Test). Data analysis was performed using IBM SPSS Statistics 17.0 (USA).Results. The study included 42 healthy individuals. The level of dyspnea perception was determined as slight (low), moderate (medium) and high in 13, 19 and 10 participants, respectively. Perceived level of breathlessness did not significantly correlate with age, gender, body mass index, physical activity, maximum airway pressure or pulmonary function test results.Conclusion. Perceived dyspnea caused by a step-up increase in additional respiratory resistance varied significantly. The perception of dyspnea was determined as slight in 31% of participants, moderate in 45% and high in 24%. The authors did not reveal a correlation between dyspnea perception and physical activity level (via IPAQ or 6 Minute Walking Test).

Authors: Mignano Nathalie 
Published: June 2023

En 1946, les Italiens ne viennent pas tous travailler dans les mines : 130 travailleurs de la province de Vicenza arrivent en 1946-47 dans l’entreprise Céramique Nationale de Welkenraedt. L’usine, désaffectée, a été détruite. Par ailleurs, les descendants des travailleurs restés sur place paraissent parfaitement intégrés. Cette immigration est-elle vouée à l’oubli ? La recherche, basée sur des témoignages et la consultation des registres de population de la commune, met en lumière la diversité des profils de ces immigrés. Elle se penche sur leurs trajectoires, leurs conditions de vie et de travail en Italie puis à Welkenraedt, et leur devenir après une expérience de durée variable dans l’entreprise. Enfin, elle interroge la deuxième génération sur ses liens avec les racines transalpines. Ce travail, qui se veut une contribution à la mémoire intrafamiliale et à la mémoire collective, a été publié avec le soutien de la Province de Liège.

Published: June 2023

Existing buildings can be at a greater seismic risk due to non-conformance to current design codes and may require structural retrofitting to improve building performance. The most recent example of that can be seen from the 2015 AD earthquake in Nepal and other sub continental regions, where numbers of buildings were destroyed with more fatal consequences have drawn the attention of the government authorities of Nepal and the general public for seismic earthquake resistance design of buildings. Following the post seismic assessment of building in Nepal after 2015 earthquake, it is revealed that the existing reinforced concrete buildings have some inadequacies in structural components and thus the intensive research and study is required to for the better understanding of the structure in terms of immediate consequences due to direct damage and way to recovery using seismic retrofit assessment.
This paper presents an overview on performance based evaluation of retrofitted rcc structural member using some advanced retrofitting techniques which is innovative and can be cost effective retrofitting strategies demanding less skilled man power. It is concluded that better seismic resilience can be achieved with the help of innovative methods with the application of innovative materials like textile mortars and fibers. In the following sections a review of experimental flexural loading on beam is presented.
