Impact of intrapartum antibiotics on the developing microbiota: a review
Authors: Arboleya Silvia , Saturio Silvia , Gueimonde Miguel
Published: July 2022

The perinatal period sets the basis for the later physiological and immune homeostasis of the individual, with the intestinal microbiota being an important contributor to driving this homeostasis development. Therefore, the initial establishment and later development of the microbiota during early life may play a key role in later health. This early establishment of the intestinal microbiota is known to be affected by several factors, with gestational age, delivery mode, and feeding habits being extensively studied ones. Other factors are not so well understood, although knowledge has been accumulating in the last years. Among them, a factor of great relevance is the effect of perinatal exposure to antibiotics. Administration of intrapartum antimicrobial prophylaxis (IAP) to women during the delivery process represents the most common form of exposure to antibiotics during the perinatal period, present in around 30% of deliveries. During the last decade, evidence has accumulated demonstrating that IAP alters intestinal microbiota development in neonates. Moreover, recent evidence indicates that this practice may also be altering the infant intestinal resistome by increasing the levels of some antibiotic resistance genes. This evidence, as reviewed in this manuscript, suggests the interest in promoting the rational use of IAP. This practice has significantly reduced the risk of neonatal infections, but now the accumulating knowledge suggests the need for strategies to minimize its impact on the neonatal microbiota establishment.

Published: July 2022

Extensive research is being conducted to create and use a wide range of alternative fuels to accommodate the world's growing energy needs. The objective of this experimental investigation was to analyze the effects of Karanja biodiesel blends on the performance, combustion, and emission characteristics of a compression ignition (CI) engine vis-a-vis neat diesel. Important physical parameters of Karanja oil were examined experimentally after transesterification and determined to be within acceptable limits. BTE of Karanja biodiesel blends was about 3-8% lower than diesel. For Karanja biodiesel blends, BSFC was about 2-9% higher than diesel but exhaust gas temperature and volumetric efficiency were lower. Emissions characteristics such as nitrogen oxides, hydrocarbons, and carbon monoxide were also analyzed for various tested fuels. Karanja biodiesel blends resulted in lesser CO and HC formation. Nonetheless, NOx emissions were around 10% greater than diesel. Peak cylinder pressure, heat release rate, and maximum rate of pressure rise versus crank angle were among the combustion characteristics parameters considered in this study. Combustion analysis revealed that for Karanja biodiesel blends heat release rate and peak cylinder pressure were lower than for neat diesel. Findings indicate that Karanja biodiesel can be considered a viable diesel engine fuel.
ROUNDABOUTS AS AESTHETIC ROAD SOLUTIONS FOR ORGANIZING LANDSCAPES
Authors: MACIOSZEK Elżbieta
Published: July 2022

In the transportation systems are different types of intersections. Among them, roundabouts are considered the safest solution. The application of roundabouts is conditioned by many factors. One of them borders on area development. Roundabouts, among others, are localized in important city places, thus serve as a landmark in the city or are localized on the boundaries of areas with different communication functions, thus constituting an organizational landscape feature. Sometimes, they diversify the space of a street or close the perspective of a monotonous street. Hence, beyond the basic functions, roundabouts with the appropriate central island arrangements can also play the function of organizing the architecture of the local area. The ways and possibilities of roundabout central island arrangements are presented in this article. An interesting central island arrangement shows that roundabouts play an esthetic and organizing landscaping role.

Published: July 2022

This work is focused on the possible ways of improving the running safety of a railway vehicle, which uses IRWs (independently rotating wheels) in a bogie. It discusses the main positive and negative properties of an application of IRWs for a railway vehicle while it is running in a curve. There are evaluated running properties of a railway vehicle in terms of safety for IRWs and a standard wheelset (SW). It is assumed that a wheelset design with IRWs will reduce the risk of derailment of a railway vehicle in a curve with a smaller radius because it will be reached a more favourable distribution of decisive forces in the wheel/rail contact. A designed wheelset with IRWs differs from other IRWs designs; in this case, only a flange can rotate independently from a wheel treat surface about the axis of rotation. Further, this research presents an analysis of a friction forces distribution of the friction forces in a contact of a flange and a rail head and a comparison with an SW. The obtained results allow concluding that it is advisable to use the wheels with the perspective wheel design (including independently rotating) to reduce the resistance to movement and improve the running properties of a railway vehicle for safety.

Published: July 2022

Road crashes remain an important public health issue. This study aimed to assess the perceived importance of four types of measures for reducing traffic crash rates. For this cross-sectional study, data were obtained from a national sample of 1,200 Spanish drivers responding to a telephone-assisted survey. The most valued types of road safety measures were those related to users’ training/education and infrastructural improvements. Further, individual perceptions were influenced by both demographic and trip-related factors. The results of this study support the idea that user features remain a relevant issue to consider when developing and implementing road safety measures.
TECHNOLOGIES FOR MONITORING THE TECHNICAL CONDITION OF TRANSPORT INFRASTRUCTURE OBJECTS BASED ON THE COEFFICIENT OF CORRELATION BETWEEN CRITICAL VALUES OF NOISE AND USEFUL SIGNALS
Authors: ALIEV Telman , MUSAEVA Naila
Published: July 2022

Transport infrastructure objects are exposed to a large number of loads, which cause the formation of displacements, bends, wear, cracks, breakdowns, corrosion, and other defects. It is shown that at the moment of initiation of malfunctions in objects, the noise of the noisy signals coming from the corresponding sensor takes critical values that correlate with useful signals. Therefore, algorithms are developed for calculating the probability of random noise accepting critical values, a coefficient of correlation between the critical values of the noise and the useful component, and a relay cross-correlation function. Technologies for monitoring the technical condition of transport infrastructure objects are proposed based on the estimates of the developed noise characteristics. Computational experiments are conducted, and the reliability of the developed algorithms and technologies is confirmed.
Polarimetric Quantum-Strong Correlations with Independent Photons on the Poincaré Sphere
Authors: Vatarescu Andre
Published: July 2022

Controllable, quantum-strong correlations of polarization states can be implemented with multi-photon independent states. Polarization-based photonic quantum correlations can be traced back to the overlap of the polarization Stokes vectors on the Poincaré sphere between two polarization filters. The quantum Rayleigh scattering prevents a single photon from propagating in a straight line inside a dielectric medium, and it also provides a mechanism for the projective measurement of polarization. Complexities associated with single-photon sources and detectors can be eliminated because the quantum Rayleigh scattering in a dielectric medium destroys entangled photons. Entanglement-free, identical sources and processing devices give rise to correlations rather than these being caused by “quantum nonlocality”. These analytic developments were prompted by the vanishing expectation values of the Pauli spin vector for a single photon of maximally entangled photonic Bell states.

Published: July 2022

The current study aimed to evaluate the influence of different sintering temperatures on the properties of copper aluminum oxide (CuAlO2) pellets synthesized from copper oxide (CuO) and aluminum hydroxide (Al(OH)3) for application in smart infrastructure systems. The pellets were sintered at 400 K, 1000 K, and 1300 K, in the presence of nitrogen gas flow to reduce the amount of oxygen availability. The CuAlO2 sintered nanoparticles were chemically analyzed by X-ray diffractometry, and the nanostructure of the materials was studied by scanning electron microscopy. The transmittance of the sintered materials was examined by ultraviolet/visible (UV/Vis) spectrophotometry, and 88% transparency was observed for the pellets sintered at 1300 K. Electrical conductivity was measured at 0.905 mS/cm, indicating a semiconducting behavior.

Published: July 2022

Along with the popularity of the Internet, people are exposed to more and more ways of micro-videos, and a huge amount of micro-video data has emerged. micro-videos have gradually become the Internet content preferred by the public, and a large number of micro-video apps have also emerged, such as Tiktok and Kwai. Intelligent classification and mining of micro-videos can greatly enhance user experience, improve business operation efficiency and enhance user experience. Through deep intelligent analysis and mining of micro-videos, important information in micro-videos can be extracted to provide an important basis for beautifying videos, content appreciation, video recommendation, content search, etc. In the past, content understanding for short videos often used human work annotation, but in recent years, with the great success of deep convolutional neural networks in image recognition, short video content understanding based on this method has gradually developed. Nowadays, most recognition algorithms extract the feature representation of each frame independently and then fuse them. However, while extracting the feature representation, some low-level semantic features are lost, which makes the algorithm unable to accurately distinguish the category of the video. At present, the algorithm of micro-video recognition based on deep learning has surpassed the iDT algorithm, making these traditional methods fade out of people’s view. In this paper according to the micro-video classification task, a new network model is proposed to concatenate features of each modality into the overall features of various modalities through the network, and then fuse the various modal features with the attention mechanism to obtain the whole micro-video features, which will be used for classification. In order to verify the effectiveness of the algorithm proposed in this paper, experiments are conducted in the public dataset, and it is shown the effectiveness of our model.

Published: July 2022

We propose versatile integrated polarizers based on geometric metasurfaces. Metasurface polarizer consists of L-shaped hole array etched on a silver film and it can generate simultaneously several polarization states including the linear polarization, circular polarization, elliptical polarization, or even hybrid polarization. Meanwhile, the combination of output polarization states changes with the illumination polarization type. The theoretical analysis provides the detail explanation for the generation of the integrated polarization states. The well-designed metasurface polarizers may generate more complex polarization modes including vector beams and vector vortex beams. The theoretical and simulated results confirm the polarization performance of the proposed integrated metasurface polarizers. The compact design of metasurface polarizers and the controllable generation of versatile polarization combinations are benefit to the applications of polarization light in optical imaging, biomedical sensing and material processing.

DEVELOPMENT OF A SYSTEM FOR MONITORING THE PARAMETERS OF THE ENVIRONMENT DURING SHRIMP BREEDING
Authors: Hryhorenko Ihor , Hryhorenko Svitlana
Published: July 2022

Today, information and measurement systems are used in almost all industries where it is necessary not only to measure the parameters of the object of control, but also to absorb the process in the object, in order to respond in a timely manner to changes in controlled parameters. Monitoring changes in the parameters of the object of control is an urgent task of modern measuring technology. When developing an information and measurement system that performs the collection, processing and transmission of information, one of the main tasks is to maintain the metrological reliability of such a system and its economic feasibility. The information and measurement system must be competitive in comparison with existing analogues. One of the promising ways to increase metrological reliability is the use of modern high-precision primary measuring transducers, as it is the analog part of the measuring channel that makes the largest contribution to the total measurement error. The article proposes to develop a system of control of environmental parameters in shrimp breeding on the basis of modern element base, which allows not only to measure with high accuracy the microclimate parameters in the shrimp tank, but also to influence the object of control through actuators. These devices switch on the water heating and aeration system if necessary. Determining the need to influence the environment is determined by the operation "comparison of the current value of the control parameter with the set value". This operation is possible thanks to the software product that is loaded into the microcontroller. The article presents a block diagram of the developed information and measurement system, electrical schematic diagram and analysis of errors in measurement channels. It is noted that the measurement error on each of the channels does not exceed 1.5%.

Published: July 2022

Shale gas resources in mainland China and its commercial exploitation has been widely focused on the Wufeng–Longmaxi Formation organic-matter-rich shale in the Sichuan Basin. However, whether southwestern margin of the Sichuan Basin can produce high-quality shale gas has not been well resolved, which might be related to the poor understanding of the relationship between Cenozoic tectonic deformation and shale gas preservation. To answer the aforementioned scientific question, we conducted a detailed work in the Mugan area to show geologic structures and gas contents in the area through seismic profiles and geochemistry analysis. Specifically, the stable Mugan syncline shows a high gas content (>2.6 m3/t measured at three boreholes D1, D2, and D3), whereas its periphery presents a poor gas content (about 0.6 m3/t measured at two boreholes X1 and Y1). Moreover, oblique fracture density and dissolved pores are much higher at boreholes X1 and Y1 than that at the other three boreholes. We propose an opposite-verging thrust fault model to explain the different gas contents and tectonic features in the Mugan area, which might indicate that regions in the southwestern Sichuan Basin with similar tectonic and stratigraphic characteristics as those in the Mugan syncline are likely to produce high-yield shale gas. This finding provides new insights into the exploration theory of shale gas in the Tibetan Plateau.
«Es mejor si eres tomboy»: construcción de identidad de género en la performance de las practicantes de covers del k-pop limeño
Authors: Saavedra Echenique Cristina
Published: July 2022

Los grupos de covers de k-pop (pop coreano) en Lima (Perú) tienen como objetivo emular a artistas coreanos (idols), tanto a nivel estético como artístico, mediante estrictas fórmulas y estructuras. Un tipo de cover es el tomboy, agrupación compuesta exclusivamente por mujeres jóvenes que interpretan a artistas masculinos, desde el corte de cabello hasta la forma de moverse en el escenario. En el afán de realizar la performance más exacta posible, las integrantes de los grupos de cover tomboy desarrollan una visualidad corporal y actitudinal que rompe una serie de reglas sociales, especialmente de género y sobre todo cuando va más allá de los escenarios y los territorios de la tribu urbana de los k-popers, es decir, cuando la performance se extrapola a la cotidianidad. La confrontación no parece ser el objetivo primordial de estas jóvenes, pero, deliberadamente o no, esta performance representa una manera de construir una identidad de género disímil al constructo social y las convenciones de la sociedad limeña.
El Perú ante la Primera Guerra Mundial: las exportaciones de La Libertad de 1917 a 1921
Authors: Ccasani Condo Miguel Ángel
Published: July 2022

Este trabajo busca reconocer que las estrategias tomadas por el Perú durante la Primera Guerra Mundial afectaron la exportación norteña. La Libertad destacó en este proceso, pues su costumbre exportadora la vinculó directamente con el conflicto bélico, y generó particularidades como el auge azucarero y la huelga de Chicama en 1920. Se investiga desde la prensa escrita, reportes oficiales y estudios estadísticos. Se concluye que la Primera Guerra Mundial afectó a las haciendas de La Libertad y mejoró sus relaciones comerciales en el sector azucarero, pero produjo una nociva dependencia regional hacia Norteamérica.

Implementation and Validation of Parasitic Stub Integrated Reconfigurable Polarization in Antennas
Authors: YADAV AJAY Kumar Singh , Yadav Rajendra Prasad
Published: July 2022

This proposed work presents a single feed radiating patch loaded with two parasitic stubs to achieve antenna polarization diversity. The primary antenna is a circular/square metallic patch with a rectangular slotted Defected Ground Structure (DGS), and it resonated at 5.5 GHz with Linear Polarization (LP). The Circular Polarization (CP) is achieved through quarter wavelength parasitic metallic stubs attached with a radiating patch using two PIN diodes which reconfigure the antenna for left hand CP (LHCP) and right-hand CP (RHCP) performances. The antenna is reconfigured its polarization modes between LP, RHCP, and LHCP by utilizing diodes switching configurations. Two antennas, a circular and a corner truncated square patch with parasitic stubs, are investigated to validate the concept of Circular Polarization (CP) using a quarter wavelength stub, and corresponding results are presented. The proposed antennas are printed on an RT/Duroid 5880 dielectric with a thickness 0.8 mm, and it provided a satisfactory agreement between measured and calculated results. The circular and square-shaped antennas have impedance bandwidth of 5.23-5.75 GHz (9.45%) for S11 less than -10dB, and measured axial ratio bandwidth (ARBW) for 3dB is approximately 5.4%.

The impact of age, physical activity, having sport, economic level and smoking on depression were independent of all other factors. most nutrients and energy inversely associated with depression (protein (p=0.043), fiber (p=0.037), iron (p=0.041), vitamin B6 (p=0.011) and caffeine (p=0.009) was independent from the energy intake). The predictor decision tree model for depression according social-economic factors is also illustrated.Conclusion: Depression can be prevalent in a nearly healthy population. Many factors can increase the risk of depression. Currently working in males and having sport, economical level, and living with someone in females were the main depression predictors. The impact of protein, fiber, iron, vitamin B6, and caffeine on depression was independent of energy intake.

Background: Sarcopenia, a progressive and generalized skeletal muscle disorder involving accelerated loss of muscle mass and muscle function, is a common condition in older individuals. This study aims to determine whether sleep latency and duration are independently associated with incident sarcopenia and to explore sex differences in these associations.Methods: A two-year longitudinal analysis of cohort study data was conducted. The sample was 70-84 years old community-dwelling participants in the Korea Frailty and Aging Cohort Study at baseline survey in 2016-2017 who completed the follow-up survey after 2 years. Logistic regression was used to calculate odds ratios (OR) for sarcopenia and sarcopenia components. Sarcopenia was defined using the 2019 Asian Working Group for Sarcopenia guidelines.Results: Among 1,353 non-sarcopenic participants in the baseline survey, 1,160 participants were classified as non-sarcopenic (85.8%) and 193(14.2%) as sarcopenic after 2 years. Long sleep duration (> 8 hours per night) was associated with incident sarcopenia in men (OR = 2.410 (95% confidence interval [CI] 1.125-5.166) after adjusting for confounding factors). Long sleep duration was specifically associated with development of low skeletal muscle mass and low muscle strength in men; adjusted ORs were 2.163 (95% CI 1.016-4.605) and 2.695 (95% CI 1.130-6.431), respectively. There was no significant association between sleep latency and sarcopenia in men (OR 1.014; 95% CI 0.505-2.036). For women, long sleep duration (OR 2.093; 95% CI 0.753-5.812) and sleep latency (OR 0.674; 95% CI 0.351-1.296) were not associated with sarcopenia.Conclusion: In men, long sleep duration was associated with incident sarcopenia, specifically the development of low muscle mass and low muscle strength, but not with low gait speed. In contrast, there was no such association for women.

Ganluo County is located in the southwestern part of Sichuan Province in China. It has strong geological tectonic movement, strong earthquake affected area and frequent debris flow disasters. There are two huge debris flows occurred in Zile Valley of Ganluo County in 1987 and 2019, a large amount of debris flow deposits went down the valley, destroyed the buildings at the mouth of the valley, causing huge property damage to local residents. In this regard, based on data of field survey and UAV aerial photography, the Arcgis and Massflow software were used to invert and analyze the movement characteristics of the debris flows occurred in 1987 and 2019, and the future activity characteristics of the valley are predicted. The results show that if the debris flow breaks out in the valley again based on the existing sources, the maximum mud depth will reach to 11.9m, the flow intensity will reach to 123.37m2/s, the total volume of material flushed out is 11.18×104m3 and the accumulation fan area is 6.925×104m2. However, after adopting reasonable engineering measures, the maximum mud depth is reduced to 8.5m, the flow intensity is reduced by 52.7% to 58.32m2/s, the accumulation fan area is reduced by 80% to 1.406×104m2 and the total volume of material flushed out is reduced by 75% to 2.75×104m3. This shows that the use of retaining measures to control the debris flow in Zile Valley can achieve good results.
Tailoring of Solidification and Crystallization Behaviour of Blast Furnace Slag for Developing Glass-Ceramics during Melt Cooling

Published: July 2022

In an attempt to develop glass ceramics during the direct cooling of molten blast furnace (BF) slag, its solidification and crystallisation behaviour are studied using the JMAK model and experimental techniques. The maximum rate of crystallisation occurs at a higher heating rate (20⁰C /min). Mould materials (copper, iron, graphite and sand mould) with different thermal conductivity are used to control the cooling rate of molten slag. XRD shows that, in the slowest cooled sample, gehlenite, akermanite and calcium aluminium magnesium silicate (CaMg2Al16O27) is formed as a crystalline phase (80 %) while the fasting cooling sample produces a 98 % glassy phase. SEM studies show that the growth and morphology of mineral phases are a function of cooling rate. Glass-ceramics with 50 % crystalline and 50 % glass phase can be produced by direct cooling in the mould materials, which has a thermal conductivity of 20-30 W/mK with a cooling rate of 120-150 K/min.

Published: July 2022

The force in metal cutting is a crucial factor that determines surface quality, tool wear, and cutting stability. It has a significant role in defining the power requirement, machine and cutting tool specifications which govern the overall machining time and cost. In this study, a force prediction approach is presented using cutting force coefficients evaluated in slot milling Al-7075 based on Taguchi's design of experiments. The adopted mechanistic approach is the inverse way to evaluate milling forces by solving the analytical models using known (measured) cutting force data. A total of 27 slot milling experiments are performed by varying the speed, feed and cutting depth to get the main effect plots considering mean values of feed and cutting forces. These plots show a strong linear correlation between feed per tooth and milling forces. Accordingly, the linear force components (Fic and Fie) and corresponding cutting force coefficients (Kic, and Kie,) are evaluated considering analogy with an equation of line. The shearing action in metal cutting is represented by shear force coefficients and plowing, friction, and rubbing action is reflected with friction/edge force coefficients. Subsequently, the forces in milling are estimated based on these force coefficients for predefined input parameters. The force coefficients and corresponding forces are also evaluated using classical mechanistic approach and results are compared. The accuracy of presented approach is verified through confirmation tests showing approximately 5 % average error compared to experimentally measured forces.

As a large-scale public transport mode, the driving safety of high-speed rail has a profound impact on public health. In this study, we determined the most efficient multi-modal warning interface for automatic driving of a high-speed train and put forward suggestions for optimization and improvement. Forty-eight participants were selected, and a simulated 350 km/h high-speed train driving experiment equipped with a multi-modal warning interface was carried out. Then, the parameters of eye movement and behavior were analyzed by independent sample Kruskal-Wallis test and one-way analysis of variance. The results showed that the current level 3 warning visual interface of a high-speed train had the most abundant warning graphic information, but it failed to increase the takeover efficiency of the driver. The visual interface of the level 2 warning was more likely to attract the attention of drivers than the visual interface of the level 1 warning, but it still needs to be optimized in terms of the relevance of and guidance between graphic-text elements. The multi-modal warning interface had a faster response efficiency than the single-modal warning interface. The auditory-visual multi-modal interface had the highest takeover efficiency and was suitable for the most urgent (level 3) high-speed train warning. The introduction of an auditory interface could increase the efficiency of a purely visual interface, but the introduction of a tactile interface did not improve the efficiency. These findings can be used as a basis for the interface design of automatic driving high-speed trains and help improve the active safety of automatic driving high-speed trains, which is of great significance to protect the health and safety of the public.

The present study investigates the effect of upstream structure on the bulk drag coefficient of vegetation experimentally by placing an embankment model with or without moat/depression upstream of the vegetation. The results indicate that in the presence of the upstream structure, the bulk drag coefficient of vegetation is decreased because the upstream structure shares the drag with vegetation. Further, it is noticed that by placing only the embankment on the upstream side, the maximum decrease in the bulk drag coefficient is 11%, and by placing both embankment and moat models on the upstream side of the vegetation, a 20% decrease in the bulk drag coefficient is observed. Based on the variables affecting the bulk drag coefficient, regression models and Artificial Neural Network (ANN) models are developed to predict the bulk drag coefficient. The results from five ANN models with different training functions are compared to find the best possible training function. The coefficient of determination (R2), Root Mean Square Error (RMSE), Nash-Sutcliffe Efficiency (NSE), Sum of Square Error (SSE), Mean absolute error (MAE), and Taylor's diagrams are used to evaluate the performance of ANN modeling techniques. The ANN model having nine neurons in each hidden layer, performs best among the five models, as this model shows the optimal values for the performance indicators, such as the highest R2 and NSE, and minimum values for the RMSE, SSE, and MAE. Finally, the comparison between the regression model and the ANN model shows that the best ANN model, achieving R2 values of 0.99 and 0.98 for the training and validation subsets, outperforms the regression models.
