Authors: Maio Giampaolo , Ding Zhihao , Truffin Karine , Colin Olivier , Benoit Olivier , Jay Stéphane
Published: October 2022

A Large-Eddy Simulation (LES) modeling framework, dedicated to ultra-lean spark-ignition engines, is proposed and validated in the present work. A direct injection research engine is retained as benchmark configuration. The LES model is initially validated using the cold gas-exchange conditions by comparing numerical results with PIV (Particle Imaging Velocimetry) experimental data. Then, the fired configuration is investigated, combining ECFM (Extended Coherent Flame Model) turbulent combustion model with Adaptive Mesh Refinement (AMR). The capability of the model to reproduce experimental pressure envelope and cycle-to-cycle variability is assessed. Within the major scope of the work, a particular focus on the Combustion Cyclic Variability (CCV) is made correlating them with the variability encountered in the in-cylinder aerodynamic variations. R3P4. Finally two post-processing tools, Empirical Mode Decomposition (EMD) and Γ3p function, are proposed and combined to analyse for the first time the aerodynamic tumble-based in-cylinder velocity field. Both tools make it possible to get deeply into the insight and visualization of the flow field and to understand the links between its cyclic variability and the combustion cyclic variability.

1H NMR Elucidation of Observed Stable Sugar-NaCl-water Complexes in Aqueous Solution
Authors: Zhu Gan , Li Hui , Li Yiqun , Gu Liuqun
Published: October 2022

The solvation of sugars in aqueous media matters in the understanding of biological systems and carbohydrate transformations. The presence of NaCl is known to perturb hydrogen bonding of sugar hydrates, however, direct evidence to elucidate mechanism at atom level is very rare even though the “NaCl Effect” was well known in biomass transformations for chemicals/biofuels. Here we report experimental evidences of a clear staircase-like correlation between induced 1H NMR changes of D-glucose/fructose with concentration of NaCl aqueous solution at room temperature; and two stable bonding status was observed in the system. An investigation on NaCl-saccharide interaction combining the calculated molar ratio of NaCl to each monosaccharide showed that chloride anions likely play a key role in both the stabilization of the two stable bonding status via formation of sugar-hydrogen (H2O)-chloride bond and induction of 1H NMR shifts. Via a further half-quantitative study, three structures of stable sugar-NaCl-water complexes were mapped for the first time in tackling the NaCl-monosaccharide interaction at atomic level in an aqueous solution. Based on the maximum of induced 1H NMR shifts, an ideal NaCl usage based on maximum of 1H NMR shift was proposed.

Published: October 2022

Subcritical water extraction (SWE) technology, as an environmentally sustainable technique, was applied to optimize the recovery of polyphenolic compounds from apple pomace (AP). Box–Behnken experimental design approach was used to investigate the effects of four process variables; extraction temperature (100-220 ºC), extraction time (30-120 min), mean sample particle size (500-1000 µm) and solid to solvent ratio (1-10 g/100 mL) on total polyphenolic compounds (TPC) yield. The SWE conditions for the optimal TPC of 39.08 ± 1.10 mg GAE per g of AP on dry basis (db) were determined to be temperature of 203.71 ºC, time of 75 min, solid to solvent ratio of 1 g/100 mL and a mean sample particle size of 500 µm. The temperature and solid to solvent ratio were determined as the most statistically significant process variables that influenced TPC yield. At the optimum conditions, antioxidant activity (% DPPH inhibition activity) of the polyphenolic extract was found in the range of 15.38–92.90% as compared to ascorbic acid (8.64–95.90%). The findings of this study proposed that SWE as a green and efficient technology provided significant advantage in term of polyphenolic compounds yield, and AP could be utilized as potential raw material for SWE of valuable antioxidant polyphenolic compounds.

Origin Invariant Molecular Orbital Decomposition of Optical Rotation
Authors: Balduf Ty , Caricato Marco
Published: October 2022

Optical rotation (OR) is a sensitive electronic property for which there are no clear structure-property relations. We proposed an approach to decompose the OR tensor in terms of one-electron transitions between occupied-virtual molecular orbital pairs, called the Sia method. This method allows to select the transitions with the largest magnitude that determine the overall value of the OR for a specific molecule, thus providing useful insights for characterization. However, the individual Sia values are origin-dependent even if the total OR is origin invariant. In this work, we explicitly identify the reason for the origin dependence of the Sia original formulations and we propose two ways to eliminate this spurious effect and define an origin invariant S ̃ia within the modified velocity gauge formalism. One approach is based on averaging the electric and magnetic-perturbed density Sia definitions (which have equal and opposite origin dependence that cancels out in the average), while the second approach is based on the equal distribution of the electronic response to an external field via Cholesky decomposition of the response matrix. Numerical results prove that the new Sia definitions are indeed origin invariant and they provide the same physical picture for the OR tensor decomposition. At the same time, we show that setting the origin of the coordinate system at the center of mass of the molecule also provides the same physical picture when using the original Sia formulation, which confirms that this is a robust approach for investigating structure-property relations in chiral molecules.
Elucidating Li5NCl2: A fully-reduced, highly-disordered nitride- halide electrolyte for solid state batteries with lithium metal anodes
Authors: Landgraf Victor , Famprikis Theodosios , Ganapathy Swapna , Bannenberg Lars , de Leeuw Joris , Wagemaker Marnix
Published: October 2022

Solid electrolytes that are thermodynamically stable against lithium metal may be key to stabilizing lithium metal/solid electrolyte interfaces which is crucial for realizing all solid state batteries that outperform conventional lithium ion batteries. In this study we investigate Li5NCl2 (LNCl) a fully-reduced solid electrolyte that is thermodynamically stable against lithium metal. Combining experiments and simulations we investigate the lithium diffusion mechanism, different synthetic routes and the electrochemical stability window of LNCl. Li nuclear magnetic resonance (NMR) experiments show that fast Li motion (σRT > 0.1 mS cm-1) is present in LNCl which is however not accessible in macroscopic LNCl pellets. Our ab-initio calculations indicate a disorder-induced wide spread of different lithium jumps in LNCl with certain jumps being much more diffusion limiting than others providing an explanation for the discrepancies in the NMR and electrochemical impedance spectroscopy (EIS) conductivity measurements. The fundamental understanding of the diffusion mechanism we develop herein will guide future synthesis optimizations for LNCl to further improve its conductivity (currently σRT = 0.015 mS cm-1) and may be applied to other highly-disordered fully-reduced antifluorite electrolytes. We further find that the previously reported anodic limit (>2V vs Li+/Li) is an overestimate and find the true anodic limit at 0.6 V which is in close agreement with our first-principles calculations. Because of LNCl’s stability against lithium metal we identify LNCl as a prospective artificial protection layer between highly-conducting solid electrolytes and strongly-reducing lithium metal anodes; Thus we also provide an investigation of the chemical compatibility of LNCl with common highly-conducting solid electrolytes.
Adapting International Standards and Ethical Principles to New Reproductive Technologies (NRTs) and Scientific Advances
Authors: Barletta Mariangela
Published: October 2022

The  advancement  of  new  technology  raises  ethical  issues.  Among  them,  human health, especially birth, is more frequently at the center of the discussions. Indeed, new technologies have the potential to radically alter human nature, such as modifying human reproduction. In recent years, it has been demonstrated that new technology can provide maternity surrogacy, as well as gene editing and the possible development of an artificial uterus. The legislative response to these issues is still fragmented and poorly regulated, inhibited by moral arguments as well as legal  systems' inability to adapt to decades-old issues like abortion. A lack of permissiveness on the side of some governments is frequently the source of disadvantages. In the case of maternal surrogacy, for example, there are frequently documented cases of abuse and corruption as a result  of legislative differences across jurisdictions. Indeed, the potential of surrogacy in certain nations encourages individuals to travel overseas and use artificial insemination treatments that are not authorized under their domestic laws. On the other hand, women who agree to give their uterus are frequently poor and forced to accept. In this regard, it would be ideal if many states could adapt their laws to  scientific advancement. Looking ahead, similar harmful trends might be seen in the development of artificial  reproductive  systems,  which  has  recently  received  research  funding.  As  a  response,  the article proposes to look at how the law should adapt to the latest innovative advancements in terms of new reproductive technologies, examining what is now achievable and what could happen in the near future from an ethical perspective.

Don’t Be Cruel
Authors: Sarch Alexander
Published: October 2022

The problem of legal luck asks why defendants who cause harm should receive more punishment than analogous actors who, simply due to luck, don’t cause harm. Here I consider one type of justification that assumes luckily harmless actors are just as culpable as their harmful counterparts. Specifically, I focus on the legislature’s reasons to ratchet down punishments for harmless wrongdoers beneath what is permitted on culpability grounds. After critiquing several such arguments (including one from mercy), I develop a more promising version based on the idea that the legislature has a duty not to be cruel. The legislature would violate this duty if it always passed laws imposing the maximum punishments permitted on culpability grounds. Withholding some punishment otherwise due harmless wrongdoers thanks to their culpability is a particularly appropriate way for the legislature to eschew cruelty. This provides a promising new justification for punishing luckily harmless misconduct less harshly.
Frequency selective surface with complex topology elements
Authors: Mayboroda D. V. , Pogarsky S. A.
Published: October 2022

Relevance: The solution of specific problems in modern technology of microwave and UHF ranges, such as the implementation of reducing the radar signature of objects, spatial frequency-selective filters, reflectors requires the development and creation of a special class of electrodynamic structures - frequency-selective surfaces. Due to the uniqueness of their electrodynamic characteristics, it is possible to solve quite technically complex problems - suppression of excited surface waves, the creation of "forbidden" zones in the amplitude-frequency characteristics.

The purpose of the work is numerical modeling and experimental study of electrodynamic characteristics of plane frequency-selective surfaces with slotted elements of complex topology. Evaluation of the influence of the geometric parameters of the slot inhomogeneity and the material constants of the dielectric substrate on the reflection and transmission coefficients of the frequency-selective surface.

Materials and methods: The paper presents the results of numerical simulation of the electrodynamic characteristics of a cell of an infinite 2D frequency-selective surface with the topology of a structural element -shaped and experimental studies of the prototype parameters. Modeling was performed within the framework of the finite element method (FEM) using the ANSOFT HFSS / ANSYS software product. Characteristic measurements are performed in free space by direct measurement of attenuation values.

Results: In the course of numerical experiments, it was found that two types of resonances can arise in the structure, associated both with the ratio of the geometric dimensions of the structural element and with the presence of double-sided shielding. The influence of the thickness of the dielectric substrate and the values ​​of the dielectric constant on the reflection and transmission coefficients is investigated. The frequency dependences of the reflection value are established with a change in the spatial orientation of the structure relative to the incident wave front. The dependence of the magnitude of the radio transparency of a two-layer frequency-selective surface on the angle of rotation of the structure around a given axis has been established experimentally.

Conclusion: The presented results of numerical simulation of the electrodynamic characteristics of a cell of an infinite 2D frequency-selective surface with the topology of a structural element -shaped and experimental studies have shown the possibility of spatial frequency selection. The totality of the results obtained makes it possible to predict the creation of sufficiently technological and highly efficient frequency-selective surfaces in the microwave range.

Published: October 2022

Background: Global and local positioning systems have a wide area of civil and military applications. Transport, logistics, precise agriculture, industrial technologies, safety systems need a strict definition of objects position on plane or in space. Existing modern positioning systems have some drawbacks in utilization and restrictions in application.

Objectives: To improve a system of local positioning on a plane that does not need a time synchronization using the impulse ultrawideband electromagnetic field of two spaced bow-tie antennas and analysis and recognition of time forms of received waves by artificial neural networks and cross correlation method. To carried out the investigation of stability of the positioning system operation in presence of an interference in the form of additive white noise.

Materials and methods: The electromagnetic simulation of excitation and radiation of the antennas is carried out by finite difference time domain method. The classification of received impulse form by known samples is realized by two alternative method, i.e. correlation approach and artificial neural networks.

Results: The utilization of correlation method and artificial neural networks permitted to realize the positioning system with angular resolution of 1 degree. The probability distributions of recognized angles for different levels of additive noise in received signals for these two techniques are obtained.

Conclusion: The comparison of artificial neural network application and correlation method for angle recognition shows that artificial neural networks can demonstrate a better precision than correlation approach. artificial neural network gives a correct angle recognition after statistical averaging of classification results even for the signal to noise ratio 0 dB. Artificial neural networks demonstrate a in three times shorter time of numerical simulation than we need for cross correlation function calculation. The application of shorter electromagnetic impulse increases the quality of angle classification in presence of the noise for both presented methods.
Increasing power of generator on nonlinear magnetic nanostructure
Authors: Volvach I. S. , Dumin O. M. , Plakhtii V. A. , Fomin P. G.
Published: October 2022

Background: One of the most promising areas of development of modern electronics is the creation of spintronic devices, which should replace the traditional semiconductor elements. The use of electron spin as a carrier of information in magnetic nanostructures can radically change modern life.

Objectives: The aim of this work is to find ways to increase the power of the generator on the magnetic nanostructure by changing its electrical circuit and more optimal external electromagnetic parameters that affect the state of electrons in the studied layered structure.

Materials and methods: The solution of this problem is carried out by numerical simulation of the magnetic nanostructure using a specially created micromagnetic simulator, which implements an algorithm for the simultaneous solution of the system of Maxwell and Landau-Lifshitz-Hilbert equations. The solution of such a complex problem is accelerated by the use of a quasi-static approximation in solving the system of Maxwell's equations, which is justified by the small size of the calculation area compared to the depth of the skin layer. Further calculations of the electrodynamic system are performed using the finite element method. To obtain the best frequency and energy parameters of the generator, it is proposed to introduce a resonant circuit to the schematic diagram of the studied generator, which is excited by short nanosecond pulses.

Results: A scheme of a generator on a magnetic nanostructure containing a resonator with concentrated parameters is proposed, and a system of nonlinear integro-differential equations with respect to electric currents is obtained in general. Numerical calculation of this system includes, in addition to the calculation of the scheme, also the modeling of a nonlinear electrodynamic structure by the finite element method. The energy and spectral characteristics of the studied generator are obtained. The search for the optimal values of the geometric parameters of the nanostructure and the magnitude of the external longitudinal magnetization is carried out.

Conclusions: Due to the complex nature of nonlinear processes in the magnetic nanostructure, the use of an external resonator, which could improve the spectral parameters of the generated current, did not give a noticeable improvement. The influence of the value of the external magnetization on the output power of the generator is complex and nonlinear, but, in general, a decrease in the level of magnetization leads to a significant decrease in power. It is established that the thickness of the magnetic layer of 6 nm is optimal for improving the energy characteristics of the generator.

Published: October 2022

Esta investigación se centró en la identificación de las unidades morfológicas y la caracterización textural y composicional de los sedimentos de fondo de la bahía de Cartagena, con información del año 2020. Se recolectaron los datos batimétricos disponibles de los últimos 20 años en el Servicio Hidrográfico Nacional, obteniendo datos de levantamientos con tecnología monohaz de los años 2000, 2004 y 2012, y un levantamiento con tecnología multihaz del año 2020. Con esta información se generaron modelos digitales de elevación con los cuales se realizó un proceso de interpretación de geoformas del fondo marino y comparación batimétrica. En este proceso se concluyó que uno de los principales cambios de las geoformas del fondo de la bahía de Cartagena es la progradación del delta y la sedimentación de hasta 18.5 m durante el periodo estudiado, lo cual fue ocasionado por el aporte sedimentario del Canal del Dique. Adicionalmente, se presentan aumentos de profundidad en sectores cercanos a puertos, los cuales pueden deberse a dragados realizados para garantizar la navegabilidad y funcionalidad de los puertos de Cartagena. Con la información textural y composicional de 85 muestras de la bahía, recolectadas cada 1 km en febrero de 2020, se identificó que en la bahía se presenta una gran influencia de sedimentos tipo litoclástico, ya que el 73 % de las muestras se encuentra en esta clasificación; mientras que solo el 4 % de las muestras se clasifica como material bioclástico. De igual forma se observó una predominancia de sedimentos lodosos, con un 65.26 % de muestras clasificadas en este rango de tamaño (4φ a 10φ), seguido de un 31.10 % de arena (-1φ a 4φ) y solo un 3.64 % de grava (φ < -1). Resaltando la prevalencia de sedimentos finos y dando soporte al argumento de varios autores, afirmando que los sedimentos calcáreos presentes en la bahía están siendo cubiertos por sedimentos terrígenos transportados principalmente por el Canal del Dique, el cual cumple un papel fundamental en la sedimentación del área.

La determinación de los campos de viento asociados a las brisas marinas es indispensable para la valoración de procesos oceánicos-atmosféricos en las zonas costeras, como el transporte de contaminantes y la generación del oleaje tipo wind sea. Con esta información es posible cuantificar efectos producidos desde el continente en el mar, así como entender los procesos de erosión costera durante el día. Es importante recalcar que en parte litoral del golfo de Urabá se realiza una frecuente disposición de plaguicidas esparcidos desde avionetas y que la costa este del golfo presenta procesos acelerados de erosión costera. En el presente trabajo se realizó la caracterización del ciclo diurno de las brisas marinas sobre las costas del golfo de Urabá, utilizando los resultados del modelo Weather Research and Forecasting (WRF). Con esta finalidad se analizaron los campos de viento y temperatura de enero y febrero de 2008 a 2013. Los valores del viento en varios niveles de la vertical, así como lo campos de viento superficial fueron comparados con información in situ. Se identificó un sistema de brisas que inicia su desplazamiento de mar a tierra entre las 07:00 y 10:00 hora local (HL) y se invierte entre las 13:00 y 16:00 HL. Una evidencia del cambio de dirección son los valores de temperatura superficial, los cuales se correlacionaron positivamente con el viento. Como trabajo futuro se espera que el modelo WRF sea implementado para años recientes, con el fin de realizar un proceso más adecuado de calibración/validación utilizando estaciones climáticas que se han instalado en los últimos años.

Authors: Abdullah Md , Abedin Mohammad Zoynal , Hossen Saddam
Published: October 2022

Fire hazards caused by leakages in gas circulation lines are dangerous and pose a threat that results in a significant loss of wealth, lives, and the environment. By adopting significant precautions, the risks of fire hazards can be reduced effectively through the use of new technologies and preventive measurements of the system. In addition, the effects of fire hazards due to leakage in gas circulation lines in the buildings as well as in the other systems can be assessed to create the context of preventive measures for a fire protection system in a way to overcome the fire hazards in gas circulation lines. The paper aims to review the effects of fire hazards due to leakage in gas circulation lines in Bangladesh. It is noted that in Bangladesh during 2018-2019, the total gas distribution line in the Titas gas system was measured as 13,138 km where the pressure-reducing system or gas riser was found as 1.2 million and the number of customers was found as 2.866 million. In the system, the number of fire accidents that occurred was 208 in the circulation system. Because of connecting the illegal gas lines and poor maintenance of the system, Bangladesh faces significant fire hazards every year. To avoid this kind of problem, proper maintenance along with the varieties of new technologies incorporating sensors and microcontrollers can be utilized.

C-statistics were applied to see discriminate accuracy of the developed regression model for family consent.Results: Knowledge (aOR= 1.63; 95%CI= 0.55 to 4.80; p= 0.380), behavioral belief (aOR= 1.11; 95%CI= 0.77 to 1.61; p= 0.580), heard organ donation (aOR= 1.12; 95%CI= 0.71 to 1.76; p= 0.630), registered for organ donation (aOR= 1.11; 95%CI= 0.50 to 2.46; p= 0.800), donated any organ/ blood/tissue (aOR= 1.63; 95%CI= 0.55 to 4.80; p= 0.380) can increased with family consent for organ donation registration. But, it’s not significantly statistic. Attitude (aOR= 1.73; 95%CI= 1.28 to 2.34; p= 0.001), control belief (aOR= 0.74; 95%CI= 0.55 to 0.99; p= 0.050), and Intention (aOR= 7.50; 95%CI= 4.04 to 13.92; p= 0.001) can increased with family consent for organ donation registration and the results were statistically significant.Conclusion: Attitude, control belief, and intention can increase family consent for organ donation registration.
Keywords: Family consent, intention, attitude, knowledge, organ donation.

Prenatal Exposure to Mercury and Adverse Birth Outcomes in Rio de Janeiro, Brazil: Rio Birth Cohort Study (PIPA Project)
Authors: Vianna Angelica dos Santos , Camara Volney de Magalhaes , De Figueiredo Nataly Damasceno , Rodrigues Froes Asmus Carmen Ildes
Published: October 2022

Background: Mercury (Hg) is a highly toxic environmental pollutant, with studies of its prenatal exposure indicating adverse birth outcomes such as low birth weight, preterm delivery, and micro- cephaly. Therefore, we analyzed prenatal Hg exposure levels and their relationship with birth outcomes in pregnant women living in an urban area in the city of Rio de Janeiro.
Subjects and Method: A cross-sectional study nested in the prospective birth cohort (PIPA Project) was conducted at the Federal University of Rio de Janeiro Maternity School from October to November 2017. A total of 117 mother-infant pairs were evaluated. The sampling technique used convenience sampling. The independent variables encompassed maternal and cord blood Hg levels, while the dependent variables were birth weight, birth length, head circumference (neonatal anthropometrics), and Apgar score at 1 and 5 minutes. The Hg levels were analyzed using induc- tively coupled plasma-mass spectrometry, and dependent variable data were obtained through medical records. Multiple regression models were applied using the SPSS.
Results: The detection rate of maternal and cord blood was 100%, with medians of 0.76 and 0.91 µg/L, respectively. A strong correlation between maternal and cord blood Hg levels was observed (r= 0.70; p<0.010), as well as an inverse association between cord blood Hg and Apgar score at 1 and 5 minutes (b=−0.47; p<0.010; b=−0.34; p<0.010) after adjusting for covariates.
Conclusion: Our study provided preliminary evidence that Hg exposure was associated with a worse Apgar score at 1 and 5 minutes. However, the relevance of this finding requires further evaluations due to its potential clinical implications concerning newborn health.

En México, ha sido un reto satisfacer la demanda nacional de arroz que superan las 850 000 toneladas anuales, por lo que en los últimos años se ha recurrido a la importación. Ante ello, a fin de contrarrestar esta situación, se ha incentivado el desarrollo de tecnologías propias a los sistemas de producción y la implementación de programas de mejoramiento genético orientados a la generación de genotipos y su adaptación a las zonas arroceras del país. A pesar de los esfuerzos, aun se carece de variedades de arroz de grano largo y delgado que son de buena calidad industrial del grano y competitivo con los arroces de importación; además, que son preferidos por el consumidor. En consecuencia, en la región arrocera de Michoacán se identificaron líneas de arroz avanzadas, donde surgió el genotipo Lombardía FLAR 13. Durante los ciclos 2017 a 2020 este material fue evaluado experimentalmente en comparación con el genotipo Milagro Filipino en Lombardía, municipio de Gabriel Zamora, Michoacán. Se registraron variables morfológicas y productivas. Con los datos obtenidos además de la verificación de las pruebas de normalidad y homogeneidad de varianzas, se analizaron con la prueba estadística t-student para muestras independientes. Los resultados mostraron superioridad del genotipo Lombardía FLAR 13 sobre el genotipo Milagro Filipino, ya que en la mayoría de las variables morfológicas evaluadas igualó, e incluso superó en las variables productivas, particularmente en esta última, los rendimientos fueron superiores a 9 t ha-1, además presentó estabilidad productiva durante los ciclos evaluados, por lo que es competitivo con la variedad convencional Milagro Filipino que se establece en la zona.
