Authors: Babajanian Bisheh Hossein , Ghodrati Amiri Gholamreza , Darvishan Ehsan
Published: December 2020

In this paper, a new structural damage detection framework is proposed based on vibration analysis and pattern recognition, which consists of two stages: (1) signal processing and feature extraction and (2) damage detection by combining the classification result. In the first stage, discriminative features were extracted as a set of proposed descriptors related to the statistical moment of the spectrum and spectral shape properties using five competitive time-frequency techniques including fast S-transform, synchrosqueezed wavelet transform, empirical wavelet transform, wavelet transform, and short-time Fourier transform. Then, forward feature selection was employed to remove the redundant information and select damage features from vibration signals. By applying different classifiers, the capability of the feature sets for damage identification was investigated. In the second stage, ensemble-based classifiers were used to improve the overall performance of damage detection based on individual classifiers and increase the number of detectable damages. The proposed framework was verified by a suite of numerical and full-scale studies (a bridge health monitoring benchmark problem, IASC-ASCE SHM benchmark structure, and a cable-stayed bridge in China). The results showed that the proposed framework was superior to the existing single classifier and could assess the damage with reduced false alarms.

Systematic studies of the ornithofauna of the Argentine Islands archipelago by Ukrainian polar explorers began in the second half of the 90s. At the beginning of the XXI-st century, the southernmost breeding site of the Snowy Sheathbill (Chionis alba), Petermann Island, was discovered by Ukrainian ornithologists; later, nesting within the Argentine Islands archipelago was recorded. Breeding and behavioural peculiarities of the Snowy Sheathbill were studied during the XX-th (April 2015 - March 2016) and the XXIII-rd (April 2018 – March 2019) Ukrainian Antarctic expeditions, in accordance with the objectives of the State Target Scientific and Technical Research Program of Ukraine in Antarctica for 2010-2020. The distribution, abundance and detection of the Snowy Sheathbill nesting sites were investigated according to generally accepted methods, by means of surveys on permanent routes, and also by the method of point counting at Cape Marina Point on Galindez Island. During the reporting period, more than 400 hours were spent on conducting morning surveys and recording. The Snowy Sheathbill nests were examined on Galindez and Petermann Islands, the sites of probable breeding were investigated on Uruguay Island and Cape Tuxen (Antarctic Peninsula). In the spring of 2015, at Cape Marina Point on Galindez Island, breeding of one pair of the Snowy Sheathbill was recorded, and in the spring of 2018 – breeding of two pairs. In the spring of 2018, clutches on Galindez Island were registered: in the first clutch - three eggs, in the other – four ones. The average egg weight was 41.0 ± 0.8 (standard deviation – 1.9 g). Under favourable nesting conditions, the hatching of the first chicks is possible in late December. The average weight of newly hatched chicks was 33.3 ± 3.6 g. From January 19 to February 28, 2018, three chicks were weighed: the average increase in the weight of the first chick was 17.9 ± 1.3 g (standard deviation 7.6 g); the increase in the weight of the second one was 17.4 ± 1.3 g (standard deviation 7.7 g); the average increase in the weight of the third chick was smaller than in previous ones and amounted to 13.8 ± 1.5 g. The days without increase in weight were recorded: for the first chick such days were on February 19, 25, 28, for the second one only two days – on February 24 and 28; for the third chick - five days (on February 4, 13, 15, 27, 28). On the 41st day, the weight of the first chick was 680 g, the second one weighed 670 g, and the weight of the third chick was about 480 g. on the 40th day.

CO2 is a harmful greenhouse gas, a product of chemical emissions, the combustion of fossil fuels and car exhausts, and it is a widely available source of carbon. The review considers various ways of hydrogenation of carbon dioxide into components of motor fuels - methanol, dimethyl ether, ethanol, hydrocarbons - in the presence of heterogeneous catalysts. At each route of conversion of CO2 (into oxygenates or hydrocarbons) the first stage is the formation of CO by the reverse water gas shift (rWGS) reaction, which must be taken into account when catalysts of process are choosing. The influence of chemical nature, specific surface area, particle size and interaction between catalyst components, as well as the method of its production on the CO2 conversion processes is analyzed. It is noted that the main active components of CO2 conversion into methanol are copper atoms and ions which interact with the oxide components of the catalyst. There is a positive effect of other metals oxides additives with strong basic centers on the surface on the activity of the traditional copper-zinc-aluminum oxide catalyst for the synthesis of methanol from the synthesis gas. The most active catalysts for the synthesis of DME from CO2 and H2 are bifunctional. These catalysts contain both a methanol synthesis catalyst and a dehydrating component, such as mesoporous zeolites with acid centers of weak and medium strength, evenly distributed on the surface. The synthesis of gasoline hydrocarbons (≥ C5) is carried out through the formation of CO or CH3OH and DME as intermediates on multifunctional catalysts, which also contain zeolites. Hydrogenation of CO2 into ethanol can be considered as an alternative to the synthesis of ethanol through the hydration of ethylene. High activation energy of carbon dioxide, harsh synthesis conditions as well as high selectivity for hydrocarbons, in particular methane remains the main problems. Further increase of selectivity and efficiency of carbon dioxide hydrogenation processes involves the use of nanocatalysts taking into account the mechanism of CO2 conversion reactions, development of methods for removing excess water as a by-product from the reaction zone and increasing catalyst stability over time.

Now polylactide (PLA) widely use as biodestructive packing material. Usually monomeric lactide produce from lactic acid. Also, methyl (ethyl) lactate could be used for lactide obtaining via its vapour-phase condensation on TiO2/SiO2 catalyst at 2600C in N2 carrier-gas flow. However, at that it is necessary to heat carrier-gas to the reaction temperature. In this communication the results on methyl lactate vapour condensation into lactide with the lowered pressure of 100-150 mbar, without carrier-gas, are presented. Supported TiO2/SiO2 catalyst with 5 wt.% titania content has been prepared by impregnation of silica with Ti(OC4H9)4. After calcination at 5000C prepared catalyst has amorphous mesoporous structure with 335 m2/g surface area and 0.83 сm3/g pore volume. The catalytic experiments were performed in such way. Liquid methyl lactate was dosed into the evaporator (2500C) and further in the flowing reactor (2600C) under pressure of 100 mbar that produced by vacuum pump. Load on a catalyst was varied from 25 to 55 mmol ML/(gcath). Cooled product was analyzed on Agilent 7820A chromatograph and NMR Bruker Avance-400 spectrometer. It was shown that TiO2/SiO2 catalyst provide 74% selectivity towards lactide at 50-53% methyl lactate conversion with lactide productivity of 7.8 mmol L/(gcath) at 2600C/100 mbar. The catalyst stable work is more 80 h. Main impurities are methyl lactoillactate, 1-methoxyethanol and 1,1-dimethoxyethane.

Ethylene glycol and propylene glycol are important representatives of polyols. On an industrial scale, they are obtained from petrochemical raw materials. Within a decade, significant efforts were made for the producing of polyols from biologically renewable raw materials - carbohydrates. The general trend for carbohydrate hydrogenolysis includes application of liquid-phase process with the use of modified metal-oxide catalysts, at 120-120 ° C and pressure of 3MPa or above. So high pressure is used for the reason to increase hydrogen solubility, and also due to the high partial pressure of low boiling solvents. We supposed that usage of high boiling solvents could allow hydrogenolysis to be performed at the lower pressure. Ethylene glycol and propylene glycol are of particular interest as such kind of solvent since they are both the main products of glucose hydrogenolysis. In this work, the process of hydrogenolysis of glucose and fructose over Cu / MgO-ZrO2 catalyst have been studied at temperature range of 160-200 °C and a pressure of 0.1-0.3 MPa in a flow reactor. The solvents were simultaneously the target products of the reaction - ethylene glycol and / or propylene glycol. Gas chromatography and 13C NMR were used for the reaction products identification. It was found that the solubility of glucose in propylene glycol is 21 % by weight, and in ethylene glycol 62% by weight. It was pointed out that the process of hydrogenolysis can take place at a pressure close to atmospheric. Under these conditions, the conversion of hexoses reaches 96-100 %. The reaction products are preferably propylene glycol and ethylene glycol. The total selectivity for C3-2 polyols is 90-94 %, that is higher than in the hydrogenolysis of glucose in aqueous solution.

Today, the use of bioethanol as an alternative motor fuel is quite relevant. Bioethanol is generally used as an additive to traditional petroleum fuels. The addition of bioethanol has a positive effect on increasing the evaporation and detonation resistance of gasoline. However, the addition of bioethanol alone may not be sufficient to fully address these issues. This article presents the results of a study of the influence of bioethanol content and cavitation field parameters on the quality of gasoline: evaporation and octane number. To determine the effect of cavitation treatment of gasoline-ethanol mixture on the physical stability of the fuel and evaporation, the content of narrow fractions, the percentage of fractions in the fuel, and the saturated vapor pressure before and after cavitation were determined. The optimal content of the biocomponent, which increases the evaporation of gasoline, has been established. The results of the change of octane number depending on the intensity of cavitation treatment for gas condensate with the addition of bioethanol are also presented. The influence of bioethanol content on the increase of octane number during cavitation treatment was determined. It is shown that the production of blended fuels by compounding with the use of cavitation treatment allows to obtain a gasoline-reference mixture with significantly better evaporation characteristics, in particular in terms of fractional composition and saturated vapor pressure, compared to gasoline-ethanol mixtures obtained by conventional mechanical compounding. In addition, it was found that the use of cavitation treatment can increase the octane number of fuels. The introduc-tion of ethanol can further increase their octane number. Thus, the introduction of ethanol and the use of cavitation treatment has a synergistic effect on improving the anti-knock characteristics of gasoline.

One of the important tasks of modern petrochemistry is the development of new additives that can improve the performance of motor fuels. With the expansion of the number of automotive and agricultural machinery and increasing its technical level, the demand for a wider range of petroleum products is increasing and, as well, the requirements for their quality are increasing. As the environmental and operational requirements for motor fuels are constantly increasing, it is necessary to find new, more efficient additives. The paper describes the synthesis of spirocyclic pyrimidine-2,4,6-trionеs by ring-closing metathesis reactions (RCM). This type of transformation is actively used in petrochemical and organic syntheses and allows to obtain compounds that are difficult to synthesize by conventional methods of organic chemistry. RCM conversion was performed using a Grubbs-Hoveyda catalyst in an amount of 5 mol. %. The compounds formed during the reaction were investigated as additives to motor fuels. Studies of the effect of synthesized spiropyrimidine-2,4,6-trione derivatives as additives on the tribological characteristics of ethanol and diesel fuel were evaluated on a four-ball tribometer in terms of critical load. At least three experiments were performed at each load. The error of the experiment was less than 5%. It was found that substances 2c and 2b increase the lubricating properties of ethanol - the critical load to the fuel burr when adding the synthesized compounds increased by 25%. Spiropyrimidine-2,4,6-trione 2b also had a positive effect on the lubricity of diesel fuel and had the effect of increasing the load to burr by 12% at a concentration of 0.032%. Thus, derivatives of spiropyrimidine-2,4,6-triones have proven to be promising compounds for the manufacture of motor fuels.

Introduction. A constant increase in the amount of space debris already constitutes a significant threat to satellites in nearEarth orbits, starting with the trajectory of their launch vehicle injection. Problem Statement. Design and development of various modern methods of protection against space debris requires knowledge of the statistical characteristics of the distribution of the kinematic parameters of the simultaneous motion of a launch vehicle injecting satellite and a group of space debris objects in the area of its trajectory. Purpose. Development of a mathematical model of a launch vehicle rendezvous with a group of observable orbital debris while injecting a satellite into near-earth orbits with an altitude of up to 2100 km and an inclination from 45 to 90 degrees. Materials and Methods. The following methods are used in the research: analysis, synthesis, comparison, simulation modeling, statistical processing of experimental results, approximation, correlation analysis, and the least squares method. Results. The simultaneous motion of a launch vehicle and a group of space debris objects has been studied. The distributions of relative distance, relative velocity, angle of encounter, and moments of time of approach of a launch vehicle to a group of the observed space debris at a relative distance of less than 5 km have been obtained. The dependence of the average rendezvous concentration on the distribution of space debris across the average altitude of the orbit and the inclination of the target orbit of the launch vehicle has been determined. The dependence of the average probability of rendezvous in the launch on the inclination of the target orbit, the number of orbital debris, and the relative distance of the rendezvous has been determined. Conclusions. The obtained mathematical model of rendezvous of a launch vehicle with a group of observed orbital debris can be used while designing means of cleaning the near-Earth space and systems to protect modern satellite launch vehicles from orbital debris. In addition, the results of the research can be used to assess the impact of unobserved orbital debris on the flight of a launch vehicle.

Introduction: Ultrasound imaging is a safe, repeatable and easily available imaging procedure. Based on these qualities, it may become a useful tool for skin assessment in newborns. Aims: The aim of the study was to evaluate the usefulness of high-frequency ultrasound imaging for neonatal skin assessment. Another aim was to identify differences in ultrasound features of the skin in newborns depending on the examination site, sex, age, birth weight, and arterial blood gas results. Material and method: A total of 72 newborns in the first 24 hours of life, without any skin lesions, were included in the study. All newborns underwent ultrasound skin examinations in three body sites (forearm, abdomen and thigh) during the first 24 hours of life. DermaMed Ultrasound Scanner with a 48 MHz probe was used for imaging. A total of three structures were identified in the ultrasound images: epidermal echo, dermis, and subcutaneous tissue. The study assessed the thickness of the epidermis and dermis, and the echogenicity of the dermis and subcutaneous tissue. Data were analysed to determine possible links with sex, post-conceptional age, body weight, birth route, and results of umbilical cord blood gas analysis. Results: Depending on the body site examined, the mean epidermal thickness was 0.081 to 0.083 mm, while the mean thickness of the dermis ranged between 0.679 and 0.722 mm. The newborns with higher birth weights were shown to have a thicker epidermis regardless of the examined site [R (correlation coefficient) for the forearm: 0.47 (p <0.001), abdomen: 0.53 (p <0.001), thigh: 0.48 (p <0.001)]. A positive correlation was found between epidermal and dermal thickness (R = 0.34; p = 0.004), but a comparison of the three examined sites revealed no significant differences in the thickness of the two structures. The sex of the newborn had no significant effect on the ultrasound features of the skin. None of the ultrasound parameters under study was found to correlate with the pH level in umbilical cord blood gas analysis. Subcutaneous oedema was detected in the examined sites in all the newborns studied. Conclusions: High-frequency ultrasound imaging may become a useful method for neonatal skin assessment, complementing existing diagnostic techniques for monitoring pathologically altered skin.
School Socioeconomic Composition as a Factor of Educational Inequality Reproduction
Authors: Kersha Yuliya
Published: December 2020

It can be inferred from international findings that school socioeconomic composition (SEC) is a major factor of educational inequality in secondary education at the school level. SEC is believed to have a positive relationship with student achievement along with individual student characteristics. However, a review of research methods used in most studies calls the existence of an influence into question.A study was carried out to evaluate causal relations between school SEC and student achievement. Multilevel regression analysis and propensity score matching (PSM) methods were applied to the panel study Trajectories in Education and Careers data in order to measure the effects of one year of study at schools with low vs. high socioeconomic composition. Correlational and quasi-experimental effect sizes were compared.Analysis results confirm that school SEC is a key factor of educational inequality in Russian secondary education, the inequality effects of school composition overlapping only partially with those of school location. Within a year of schooling, ninth-graders with similar individual characteristics may lose up to a quarter of standard error in PISA‑2012 scores if attending a school with low socioeconomic composition, while attending a high-SEC school would improve their educational outcomes by the end of the ninth grade. Negative effects were observed for two subject areas, which allows suggesting a systematic impact of SEC on student achievement. The final part of the article describes the theoretical and practical significance of the findings and presents the main directions of further research in this field.

BackgroundLifestyle management has been proved to improve both metabolic and reproductive outcomes for women with polycystic ovary syndrome (PCOS). In China, WeChat has become the most popular social media platform. Previous studies have confirmed the effectiveness of WeChat in health intervention and its potential to improve health behaviours. Therefore the present study tried to investigate the efficacy of online education through WeChat public account on the lifestyle interventions of women with PCOS.MethodsWe set up a cross-sectional study between January 2020 and July 2020. Data were collected through online questionnaires. All participants completed a questionnaire, including age, educational level, WeChat activeness, physical exercise, dietary habits, self-reported symptoms and medical history.ResultsA total of 258 women were included in this study, including 96 women with PCOS (PCOS group) and 162 women without PCOS (control group). Among them, 130 women followed our WeChat public account (follower group) and 128 women did not follow the WeChat public account (non-follower group). There were no significant differences in terms of physical activity assessment and dietary assessment between the PCOS and control groups (P>0.05), neither between the followers and non-follower groups (P>0.05). ConclusionsApplication of WeChat public account seems useless in lifestyle management for women with PCOS, however, the conclusion might be limited by the small sample size.

Human enhancement, biocyborg and self-experimentation: biopower in the age of synthetic biology and gene editing
Authors: Pio-Lopez Léo
Published: December 2020

Synthetic biology and gene editing opens new possibilities for human enhancement requiring ethical, societal and biopolitical considerations to evaluate its implications on the biopower and the human species. In this article, from a critical and exploratory analysis, we advocate that recent biotechnological developments allowed by synthetic biology (including gene editing) are transforming the line of forces of biopower and biopolitics. After having described the paradigm of life as an engineering discipline conveyed by synthetic biology, we first analyze using the concept of somatechnology that this technoscience is transforming the figure of the cyborg towards the biocyborg blurring the distinctions natural/artificial and man/machine. In second, we investigate the bioeconomy of enhancement and its effect on how the individuals developed new modes of subjectivation and how they consider their own bodies. We end the article by analysing the transformations of biopower with gene editing and the use of technologies of genetic self-modification by self-experimenters.

Miriam Chaszczewacka’s Diary
Authors: Tych Feliks
Published: December 2020

Diary of Miriam Chaszczewacka, a teenage resident of Radom. She wrote it since August 1939 – she started on the eve of the Third Reich’s attack on Poland – until the end of October 1942, when she was killed during the liquidation of the ghetto. Written in Polish, conceived as a letter to the future generations, Miriam’s diary shows the daily life in the ghetto and the extermination of its population based on the example of Radom. Her diary entries are mostly spontaneous notes of a young girl writing about her life. But she also describes the deteriorating conditions of the life in the ghetto and the general political situation. Thisis a dramatic record of the increasing awareness of the inevitably approaching death.
Discurso governamental: “Com o novo Ensino Médio, você pode decidir o seu futuro!”

Published: December 2020

Esta pesquisa teve como objetivo a análise dos discursos que tem efeito de verdade, que foram divulgados pelo Ministério da Educação (MEC) e pelo Governo Federal materializados em propagandas governamentais no canal do MEC no YouTube. Nesse canal foi selecionado o corpus para a realização desta pesquisa, a propaganda governamental intitulada “Com o Novo Ensino Médio você pode decidir o seu Futuro!” Para fundamentar teoricamente esta pesquisa pautou-se nos estudos de Michel Foucault (1995, 2014, 2018). O questionamento que norteou este estudo foi: Qual o discurso com efeitos de verdades dos macropoderes foi reproduzido nos discursos dos micropoderes materializados na propaganda “com o Novo Ensino Médio você pode decidir o seu Futuro” para o assujeitamento dos corpos? Após a análise, constatou-se os seguintes discursos que circularam como se fossem verdadeiros: (1)a mudança da organização referente ao Ensino Médio é algo promissor para o futuro dos alunos. (2) Os estudantes que optarem pelo itinerário formativo Formação Técnica e Profissional, ao concluir o ensino terá uma vaga imediata no mercado de trabalho. (3) O estutante poderá escolher as áreas de conhecimento do seu interesse e, assim, decidir sobre o próprio futuro. (4) a reestruturação do Ensino Médio aconteceu em momentos de boas vibrações, pensamentos positivos e situações políticas e sociais favoráveis para atender os  anseios educacionais dos jovens brasileiros. Após a investigação refletiu-se  que  aceitar o discurso governamental com efeito de verdade como se o discurso fosse a  própria verdade é ingênuo, pois é preciso questionar sobre os  discursos que são transmitidos pelos meios de comunicação.

Lineages within the species Limosilactobacillus reuteri have specialized to various hosts and their genomes reflect these adaptations. The pdu-cbi-cob-hem gene cluster is conserved in most human and poultry isolates but is infrequent in rodent and porcine isolates. This gene cluster confers the transformation of glycerol into 3-hydroxy-propionaldehyde (reuterin), which can either be secreted and function as precursor of the antimicrobial compound acrolein or serve as an electron acceptor that enhances the organisms’ growth rate. However, it remains unclear which of these two functions is more relevant for L. reuteri evolution and ecology. Here we characterized the effect of glycerol on growth rate and reuterin formation in L. reuteri strains across different phylogenetic lineages during growth on ecologically relevant carbohydrates. We further evaluated the innate reuterin resistance among these strains to infer a possible role of reuterin in the evolution of strains. Results revealed that the poultry/human lineage VI strain, L. reuteri DSM 17938 shows more growth enhancement through glycerol and greater capacity for reuterin production on glucose and maltose as compared to human lineage II strains. Interestingly, reuterin production in lineage II strains was significantly elevated on raffinose and lactose, reaching levels similar to DSM 17938. On all carbohydrates tested, reuterin production occurred during the exponential growth phase and became undetectable during the stationary growth phase. The amount of reuterin produced was sufficient to inhibit E. coli, suggesting that it could be ecologically relevant, but the resistance towards reuterin among L. reuteri strains was highly variable and, for the most part, unrelated to the strain’s capacity for reuterin production. Overall, the findings suggest differences in the substrate-specific regulation of the pdu cluster in L. reuteri lineages that might be reflective of their ecological niches, e.g., chicken foregut versus human infant and adult large intestine. Such information can inform future studies on the ecology of L. reuteri and guide the development of synbiotic applications to improve the therapeutic use of this species.
At-Risk Testing for Pompe Disease Using Dried Blood Spots: Lessons Learned for Newborn Screening

Published: December 2020

Pompe disease (GSD II) is an autosomal recessive disorder caused by deficiency of the lysosomal enzyme acid-α-glucosidase (GAA, EC 3.2.1.20), leading to generalized accumulation of lysosomal glycogen especially in the heart, skeletal, and smooth muscle, and the nervous system. It is generally classified based on the age of onset as infantile (IOPD) presenting during the first year of life, and late onset (LOPD) when it presents afterwards. In our study, a cohort of 13,627 samples were tested between January 2017 and December 2018 for acid-α-glucosidase (GAA, EC 3.2.1.20) deficiency either by fluorometry or tandem mass spectrometry (MS). Testing was performed for patients who displayed conditions of unknown etiology, e.g., CK elevations or cardiomyopathy, in the case of infantile patients. On average 8% of samples showed activity below the reference range and were further assessed by another enzyme activity measurement or molecular genetic analysis. Pre-analytical conditions, like proper drying, greatly affect enzyme activity, and should be assessed with measurement of reference enzyme(s). In conclusion, at-risk testing can provide a good first step for the future introduction of newborn screening for Pompe disease. It yields immediate benefits for the patients regarding the availability and timeliness of the diagnosis. In addition, the laboratory can introduce the required methodology and gain insights in the evaluation of results in a lower throughput environment. Finally, awareness of such a rare condition is increased tremendously among local physicians which can aid in the introduction newborn screening.

Выявлена статистически значимая прямая связь между значением индекса Бартел и результатами тестов оценки когнитивных функций и мобильности, а также статистически значимая обратная связь индекса Бартел с риском падений у пациентов пожилого возраста. Было определено, женщины больше ограничены в повседневной активности и зависимы от окружающих

The aim of this study was to assess the basic activity in everyday life in patients in the Gribanovsky boarding house for the elderly and disabled, determining the factors affecting it and the possibility of their correction. The study involved 51 patients living in a boarding house, the average age was 74.7 ± 1.4 years. Basic activity in everyday life (Bartel index), cognitive functions (according to the mini-KOG test), physical functioning (using the Short Battery of Physical Functioning Tests) were evaluated, the risk of falls on the Morse scale was calculated. Significant relationships between the Bartel index value and the results of tests for assessing cognitive functions, mobility and the risk of falls were identified, and their association with sex and age was assessed. A statistically significant direct association between the Bartel index value and the results of cognitive and mobility assessment tests was identified, as well as a statistically significant inverse association of the Bartel index with the risk of falls in elderly patients. It was determined that women are more limited in daily activity and dependent on others
