Unlike other studies that only determined the chemical composition of essential oils depending on their geographic origin, this research investigated the effect of weather conditions (temperature, precipitation, and insolation) on the chemical composition of Nepeta nuda L. essential oil. The collection of wild-growing N. nuda was carried out during three successive years, 2019, 2020, and 2021 at Rtanj Mountain (Serbia) on the same date (July 7th). Essential oil extraction from the plant was performed by hydro-distillation. After gas chromatographic-mass spectrometric analysis, a total of 102 volatile compounds were separated from N. nuda, during the observed period, 28 were unidentified, compromising between 5.0% and 8.7%, depending on the year. A multiple linear regression model was created, and statistical analyses were performed to provide knowledge about the prediction, feature profile, and the similarity in contents of active compounds of the N. nuda essential oil. The influence of temperature on the accumulation of the most abundant component, 1,8-cineole, was positive, while the impact of precipitation and insolation was negative. According to the cluster tree, there are four chemotypes of N. nuda essential oil: with nepetalactone, 1,8-cineole, mixed (nepetalactone+1,8-cineole+germacrene D), and nonspecific chemotypes. Bearing in mind that the biological activity of a raw material depends on the chemotype and environmental factors, this is a topic that deserves a more detailed approach. The N. nuda and its essential oil are promising materials with high biological potential, and these deserve further detailed investigation.
Grain Scale Investigation of the Mechanical Anisotropic Behavior of Electron Beam Powder Bed Additively Manufactured Ti6Al4V Parts

Published: January 2022

Numerous factors, including variable grain structures and different inherent defects, impact the mechanical behavior of Ti6Al4V parts fabricated using metal Additive Manufacturing (AM) processes. This study focuses on an in-depth analysis of how different microstructural features, such as crystallographic texture, grain size, grain boundary misorientation angles, and inherent defects, as byproducts of the electron beam powder bed fusion (EB-PBF) AM process, impact its anisotropic mechanical behavior. Standard tensile testing, conducted on samples produced at different orientations relative to the build table, showed significant anisotropy in elastic-plastic constitutive characteristics. Furthermore, X-ray computed tomography (CT) and electron back-scattered diffraction (EBSD) analyses were conducted on as-built samples to assess the effects of inherent defects and microstructural anomalies on such behavior. The samples arranged vertically and parallel to build direction had an average porosity of 0.05%, while the horizontally built samples, which were perpendicular to the build direction, had an average porosity of 0.17%. Moreover, the vertical samples showed larger grain sizes, with an average of 6.6 µm, wider α lath sizes, a lower average misorientation angle, and subsequently lower strength values than the other two horizontal samples. Among the three strong preferred grain orientations of the α phases, <1 1 2¯ 1> and <1 1 2¯ 0> were dominant in the horizontally built samples, whereas the <0 0 0 1> orientation was dominant in vertically built samples. Finally, larger grain sizes and higher beta-phase volume ratios were observed in the areas located at distances further away from the build plate. This was possibly due to the change in thermal gradients, cooling rates, and some thermal annealing phenomena resultant from the elevated build chamber temperature.
RUSSIAN EXPERIENCE OF RESEARCH IN THE FIELD OF BUILDING MATERIALS WITH THE FUNCTION OF SELF-HEALING
Authors: Inozemcev S. , Do T. , Korolev E. 
Published: January 2022

The results of the analysis of scientific and technical literature, reflecting the experience of research of Russian scientists in the field of self-healing of building materials are shown. They are presented in publications included in international bibliographic and abstract databases. The tendency of changes in the number of publications over 10 years indicates an exponential growth in the interest of researchers in the ability of self-healing, most of the works (more than 50%) published in the field of materials science. The total number of publications by Russian authors over ten years devoted to self-healing is 206 works, of which 49% are in the field of materials science.
An analysis of articles in publications included in international bibliographic and abstract databases published by domestic authors shows that methods of creating a material structure, which contains additional elements in the form of a reserve volume of a structure-forming substance, are proposed to implement the self-healing effect. Such elements are capsules or functional layers with a reducing agent, the destruction of which triggers the recovery (healing) process. Works are presented where the recovery effect is achieved due to the binder's own potential, which is not fully realized at the initial stage of structure formation. The authors have proposed the implementation of the self-healing effect in composites based on a hydraulic mineral binder (cement) and an organic binder (bitumen) or polymer. At the same time, in most cases, there is no mathematical description of self-healing mechanisms.

Published: January 2022

In injection molding processes for thermoplastic parts, the polymer solidification phase in the molding cavity has a strong influence on the quality of the shaped parts and also on the process cycle time. Reducing cycle time is one of the major concerns for plastic injection industries. As cooling phase presents the most critical phase to get quality and cycle time of the part, the application of additive manufacturing (AM) technologies has been overcoming the limitations of traditional cooling system design. AM enables the construction of conformal cooling channels for higher cooling uniformity due to its almost unlimited freedom of design that can fulfil the desired functions in injection molding process equipment. The analysis of the heat transfer during the phase of cooling allows the investigation of the optimal positioning of the cold sources and their intensities. In this paper, a systematic approach is used to replace conventional channels in an injection molding tool with conformal cooling channels. A simulation is used to develop a numerical model that describes the heat transfer and predicts the cycle time of both the optimal and conventional designs. Finally, a numerical comparison is made between traditional and conformal cooling to demonstrate the beneficial effect on reducing the manufacturing cycle and enhancing part quality.

De Marivaux à Scribe : les illusions de l’identité
Authors: Bénac-Giroux Karine 
Published: January 2022

Du Jeu de l’amour et du hasard de Marivaux (1730) au Valet de son rival de Scribe (1816), quelles évolutions connaît la représentation de l’identité ? Si les deux intrigues s’avèrent déceptives pour les personnages, marqués par un déterminisme social et psychologique certain, l’émergence d’un sujet pluriel, déjà latente chez Marivaux, trouve chez Scribe à se manifester dans le recours à la métathéâtralité du faux valet mais vrai rival, dont le jeu avec la fiction révèle un espace de mouvance identitaire qui préserve quelque peu la légèreté d’une comédie marquée par ailleurs d’un cynisme éclatant et de codifications sociales et genrées très figées.
Robustness of organic physically unclonable function with buskeeper circuit for flexible security devices

Published: January 2022

AbstractFlexible devices have been studied to realize IoT or novel wearable devices. The data that flexible devices deal with can include personal information when application areas further expand. A security system for flexible devices becomes more important in this case. In this study, we investigate the thermal stability of an organic flexible security system. The security system utilizes fabrication variation of a chip, and it is called a physically unclonable function (PUF). As a result, the bit error rate of the organic PUF is 1.8% and the index of ID uniqueness (i.e., randomness) has an almost theoretical value of 0.48. The generated ID remains even after annealing at 100 °C for 97 h by using CYTOP encapsulation. X-ray diffraction measurement implies that degradation of PUF characteristics partially derives from structure changes of the organic n-type semiconductor thin film after annealing.

Published: January 2022

Abstract
In this work, we fabricated Ga2O3(001)/Si(100) and Ga2O3(010)/Si(100) heterointerfaces by surface activated bonding at room temperature and investigated the effect of Si thickness on the thermal stability of the heterointerfaces by heating the bonding samples at different temperatures. The heterointerface with a thin Si exhibited a good thermal stability at 1000 °C. A 4 nm thick intermediate layer with a uniform thickness was formed at the as-bonded Ga2O3(001)/Si(100) heterointerface, but for the as-bonded Ga2O3(010)/Si(100) heterointerface, an intermediate layer with a non-uniform thickness was formed. The thickness of both intermediate layers ranged from 3.6 to 5.4 nm and decreased after annealing at 500 °C, followed by an increase after annealing at 1000 °C. The component of the intermediate layer includes Ga, O, and Si atoms.

Plasmon-induced transparency in borophene waveguide with strong absorption inhibition at critical-coupled state
Authors: Ma Rui , Zhang Lian-gang , Liu Gui-dong , Wang Ling-ling , Lin Qi 
Published: January 2022

Abstract
We propose a critical-coupled plasmon-induced transparency borophene waveguide system in a communication band with strong absorption inhibition. Intrinsic loss of this scheme is strongly suppressed by coupling between critical-coupled bright mode and dark mode, and then the purpose of reducing absorption can be achieved. Based on numerical calculation by finite-difference time-domain simulations and theoretical analysis via coupled mode theory, the transmission characteristics of this system are investigated. It turns out that this approach effectively minimizes excess absorption losses and maximizes the amount of transmitted energy. Our results may provide an alternative way to design lab-on-a-chip borophene devices.

Authors: Aulia  , Sumiatin Titik , Su’udi Su’udi 
Published: January 2022

The COVID-19 outbreak began in December 2019. In preventing its transmission, society across the world agrees to use a mask for their safety. However, today, people, primarily some merchants who sell their stuff around the tourism places, still do not obey the regulation to wear a mask. Hence, this study aims to know the relationship between merchant knowledge and attitude toward the obedience of using a mask in preventing the COVID-19 transmission at the religious tourism of Sunan Bonang Tuban. The research design used in this study is the correlation analysis that uses a cross-sectional approach. Moreover, the sampling technique used in this study is Simple Random Sampling with 105 populations and 83 samples of merchants. The data technique used in this study is a questionnaire. Then, the researcher analyzes the questionnaire with a percentage and does a crosstab by using the Spearman Rank Correlation test. The finding of this study presents that most of the merchants at religious tourism of Sunan Bonang Tuban have good knowledge in preventing COVID-19 transmission. It is about Forty-nine people (59,0%). Then, fifty people (60,2%) have a positive attitude. Moreover, the finding presents that almost half of the merchants, thirty-five people (42,2%), obey the regulation to wear the mask. The result of Spearman Rank Correlation test is α =0.00 < 0.05. This result shows the relationship between knowledge and obedience in using the mask. The result of the test is α =0.00 < 0.001 shows there is a relationship between the attitude and the obedience in using the mask of merchants to prevent COVID-19 at the religious tourism of Sunan Bonang Tuban. The knowledge and attitude of merchants influence their obedience in using the mask. It means that the more increased merchants' knowledge and attitude, the more increased merchant obedience. In increasing and encouraging other merchants' knowledge and attitude, the government must have a good strategy. One of the appropriate strategies is doing counseling of using a mask to prevent COVID-19 transmission.

Routine hematology tests are one of the supporting tests in diagnostics to assess the severity of the disease and predict risk in COVID-19 patients, and can be used as supporting data on RT-PCR tests. Some blood tests that are widely used as monitoring tools and predicators of COVID-19 are the number of leukocytes, the number of lymphocytes, the number of neutrophils, the number of platelets and NLR (Neutrophil lymphocyte ratio). Thrombocytopenia occurs due to excessive use of tromocytes in the body as compensation for damage to lung parenchym cells, the lungs are organs where platelets are released from megacaryocytes, so this damage causes disruption of platelet maturation process. The type of research used is quantitative descriptive with the aim to find out the results of blood tests complete with platelet parameters in patients infected with the COVID-19 coronavirus at Muhammad Noer Pamekasan General Hospital. The results of the study were platelet count test results at normal productive age of 67 respondents (96%) and decreased platelet count (Thrombocytopenia) by 3 respondents (4%). While in normal elderly age a number of 26 respondents (87%) and a decreased platelet count (Thrombocytopenia) amounted to 4 respondents (13%).
