OsCSLD1 Mediates NH4+-Dependent Root Hair Growth Suppression and AMT1;2 Expression in Rice (Oryza sativa L.)
Authors: Rajendran Sujeevan , Kim Chul Min 
Published: December 2022

Root hairs play crucial roles in the roots, including nutrient uptake, water assimilation, and anchorage with soil, along with supporting rhizospheric microorganisms. In rice, ammonia uptake is mediated by a specialized ammonium transporter (AMT). AMT1;1, AMT1;2, and AMT1;3 have been extensively studied in relation to nitrogen signaling. Cellulose synthase-like D1 (CSLD1) is essential for cell expansion and is highly specific to root hair cells. csld1 mutants showed successful initiation but failed to elongate. However, when nitrogen was depleted, csld1 root hairs resumed elongation. Further experiments revealed that in the presence of ammonium (NH4+), csld1 roots failed to elongate. csld1 elongated normally in the presence of nitrate (NO3−). Expression analysis showed an increase in root hair-specific AMT1;2 expression in csld1. CSLD1 was positively co-expressed with AMT1;2 changing nitrogen concentration in the growth media. CSLD1 showed increased expression in the presence of both ammonium and nitrate. Methylammonium (MeA) treatment of CSLD1 overexpression lines suggests that CSLD1 does not directly participate in nitrogen transport. Further studies on the root hair elongation mutant sndp1 showed that nitrogen assimilation is unlikely to depend on root hair length. Therefore, these results suggest that CSLD1 is closely involved in nitrogen-dependent root hair elongation and regulation of AMT1;2 expression in rice roots.

Aristolochic acids (AAs) are a group of nitrophenanthrene carboxylic acids present in many medicinal herbs of the Aristolochia genus that may cause irreversible hepatotoxicity, nephrotoxicity, genotoxicity and carcinogenicity. However, the specific profile of AAs and their toxicity in Aristolochia plants, except for AAs Ι and ΙΙ, still remain unclear. In this study, a total of 52 batches of three medicinal herbs belonging to the Aristolochia family were analyzed for their AA composition profiles and AA contents using the UPLC-QTOF-MS/MS approach. The studied herbs were A. mollissima Hance (AMH), A. debilis Sieb.etZucc (ADS), and A. cinnabaria C.Y.Cheng (ACY). Chemometrics methods, including PCA and OPLS-DA, were used for the evaluation of the Aristolochia medicinal herbs. Additionally, cytotoxicity and genotoxicity of the selected AAs and the extracts of AMH and ADS were evaluated in a HepG2 cell line using the MTT method and a Comet assay, respectively. A total of 44 AAs, including 23 aristolochic acids and 21 aristolactams (ALs), were detected in A. mollissima. Moreover, 41 AAs (23 AAs and 18 ALs) were identified from A. debilis Sieb, and 45 AAs (29 AAs and 16 ALs) were identified in A. cinnabaria. Chemometrics results showed that 16, 19, and 22 AAs identified in AMH, ADS, and ACY, respectively, had statistical significance for distinguishing the three medicinal herbs of different origins. In the cytotoxicity assay, compounds AL-BΙΙ, AAΙ and the extract of AMH exhibited significant cytotoxicities against the HepG2 cell line with the IC50 values of 0.2, 9.7 and 50.2 μM, respectively. The results of the Comet assay showed that AAΙ caused relatively higher damage to cellular DNA (TDNA 40–95%) at 50 μM, while AAΙΙ, AMH and ADS extracts (ranged from 10 to 131 μM) caused relatively lower damage to cellular DNA (TDNA 5–20%).

Published: December 2022

Puberty represents the period in which athletes go through many changes from a physical, morpho-functional and psychological point of view. Also, in the age range between 13-14 years, the training of athletes registers a gradual increase in the volume and intensity of training, which determines special attention on the methods and means used during training. This study was carried out with the aim of identifying the level of development of the motor indices directly involved in the practice of the handball game. The research methods used during this study were: the method of analyzing specialized and interdisciplinary literature, the pedagogical observation method, the statistical-mathematical method and the tabular method. Following the study, we would like to emphasize the urgent need to update the performance scales specific to the game of handball and develop unitary training models, from the perspective of the content of the training process for each age group.
Sustainable Development, Globalization, Non-antagonistic Development, Philosophical Environmentalism and Endangered Democracy
Authors: Sztumski Wiesław 
Published: December 2022

In this paper, one discusses the conditions favourable for sustainable development, limitations of it in the social reality and the sense of implementing it everywhere. The author points out that sustainable development has always taken place in nature thanks to the mechanisms of self-regulation and the laws of nature. However, what is new is the idea of sustainable development in the social reality. Balancing inequalities to the end, i.e. until the state of permanent equilibrium of social systems is achieved, leads to stagnation. Because the source of sustainable development is throwing off equilibrium, and stabilization kills development. He also indicates that the idea of sustainable development was not born out of ecological, but economic reasons, and still serves mainly economic, not ecological purposes. It works best in the sphere of the economy. Nevertheless, it is implemented everywhere with a better or worse result, because the world fashion for sustainable development and its mythologization has prevailed. One sees in it a panacea for all social problems. In fact, it is a tool of self-regulation in social systems that ensure the survival of them. There is a feedback loop between sustainable development and globalization. Sustainable development contributes to globalization, and globalization promotes sustainable development. However, only until one reaches some critical moment. Then, globalization begins to hinder sustainable development and eventually makes it unfeasible. The condition for the implementation of sustainable development is the freedom provided by the democratic system. Therefore, it works best in a liberal democracy. Unfortunately, this democracy is already collapsing. It has taken on a caricature form that makes difficult for people to live and for governments to exercise power. Therefore, one replaces it by totalitarian or fascist regimes, which for different reasons gives greater hope for a better functioning of the state. However, totalitarianism limits freedom significantly and fascism, in addition, raises legitimate fear due to negative historical experiences. There is no place for sustainable development in these regimes. That is why many researchers and politicians want to stop fascism and bring about sanitation of democracy with New Enlightenment, New Metanoia, and New Humanism. In such way, they want to enable further sustainable development.
First-principles study of anomalous Hall effect and anomalous Nernst effect in Fe2Si

Published: December 2022

Abstract
We have performed density functional calculations of the electronic structure, anomalous Hall conductivity, and anomalous Nernst conductivity for the model crystal structure of a mineral Hapkeite Fe2Si contained in a meteorite Dhofar 280, which is believed to originate from the Moon. The calculated results showed that the model structure of Hapkeite Fe2Si exhibits a larger transverse thermoelectric effect than bcc-Fe and hexagonal Fe2Si. Based on the detailed analysis of the electronic structures and transport coefficients, we found that the origin of the large transverse thermoelectric effect is due to an anomaly in the density of states at the interface between the Fe layers and the Si–Fe alternative stacked layers. This finding is promising for the design of new transverse thermoelectric materials.

Abstract
In this study, we developed a capacitorless dynamic random-access memory (DRAM) (1T-DRAM) device based on a junctionless (JL) bulk-fin field-effect transistor structure with excellent reliability and negligible variability against work-function variation (WFV). We investigated the variation in the transfer characteristics and memory performance of the memory cell owing to WFV. In particular, to investigate the WFV effect, we analyzed the transfer characteristics and memory performance of 200 samples using four metal-gate materials—TiN, MoN, TaN and WN. Consequently, we discovered that the WFV affected the transfer characteristics of the JL bulk-fin field-effect transistor. However, the proposed 1T-DRAM demonstrated that the sensing margin and retention time produced minimal effect owing to the adoption of a structure storing holes in the fin region. Consequently, the proposed 1T-DRAM exhibited strong WFV immunity and excellent reliability for memory applications.

Mode conversions for elastic waves transmitted and reflected by ultrathin elastic metamaterial plates with anisotropic resonances
Authors: Yu Wenjie , Peng Pai , Hu Wei , Du Qiujiao , Liu Fengming 
Published: December 2022

Abstract
In this work, we study the conversions between longitudinal and transverse modes by one layer of oblique anisotropic dipolar resonators, whose size can be orders smaller than the wavelength. Mode conversions are found for both transmitted and reflected waves by such small resonators with a normal incidence. A mass-spring model is proposed to depict analytically the mode conversion, giving simplified analytical expressions for the conversion rates. The reflected conversion will gradually increase to the maximum while the solid material behind the resonators becomes soft, or vice versa. This work may provide theoretical guidance for practical applications.

Published: December 2022

В статье рассматривается определение суммарных нелинейных сил и соответствующих амплитуд второго порядка различных видов качки на основании применения трехмерной потенциальной теории. Проведена оценка влияния отдельных составляющих нелинейных сил в суммарном силовом воздействии на судно. Выполнено сравнение расчетов амплитудно-частотных характеристик второго порядка с расчетами по различным двумерным методам. Показано хорошее согласование результатов между собой в большинстве случаев. Показано, что влияние нелинейных сил приводит к появлению супергармонических резонансных режимов вертикальной, бортовой и килевой качки, имеющих место в зоне частот в два раза меньших соответствующих собственных частот. Приведены результаты расчетов амплитуд вторых гармоник на различных курсовых углах. Показано, что наибольшее влияние нелинейные факторы имеют место при расположении судна лагом. Приведены результаты расчетов амплитудно-частотных характеристик поперечных видов качки с учетом нелинейных факторов. Показано их значительное влияние в зоне низких частот.
The article considers the determination of the total nonlinear forces and the corresponding amplitudes of the second order of various types of motions based on the application of three-dimensional potential theory. An assessment of the influence of individual components of nonlinear forces in the total force effect on the ship was carried out. The calculations of the amplitude-frequency characteristics of the second order are compared with the calculations by various two-dimensional methods. Good agreement between the results was shown in most cases. It is shown that the influence of non-linear forces leads to the appearance of superharmonic resonant modes of heave, roll and pitch modes of motions occurring in the frequency zone twice as low as the corresponding natural frequencies. The results of calculations of the amplitudes of the second harmonics at different heading angles are presented. It is shown that the greatest influence of non-linear factors takes place during the motions in beam waves. The results of calculations of the amplitude-frequency characteristics of transverse types of motions are given, taking into account non-linear factors. Their significant influence in the low frequency zone is shown.

Статья является обобщением ранее выполненных работ mamsar и рассматривает методику расчета амортизации судовой электростанции на примере СДГА-500 с неуравновешенным приводным дизелем 5ЧН 25/30 с учетом влияния упорных бортовых, носовых и кормовых виброизоляторов. Расчеты амортизации СДГА усложняются, если приводной дизель неуравновешенный, а упорные виброизоляторы относительно несущей рамы установлены без зазоров. Целью представленной методики является исследование влияния упорных виброизоляторов на эффективность виброизоляции общей системы амортизации и обоснование необходимости расчета амортизации СДГА с учетом влияния упорных виброизоляторов. Методика расчета амортизации предусматривает порядок представления: схем опорной и упорной систем амортизации с соответствующими компонентами; исходных данных; последовательности расчетов амортизации по двум вариантам – без учета и с учетом влияния упорных виброизоляторов и построения частотных диаграмм. Частоты свободных колебаний без учета влияния упорных виброизоляторов на 30–54% меньше значений, соответствующих частотам с учетом влияния упорных виброизоляторов, что свидетельствует о целесообразности расчета амортизации агрегата с учетом влияния упорных виброизоляторов.
The article is a generalization of MAMSAR's previously performed work and examines the methodology for calculating the vibration isolation of a ship's power plant using the example of SDGA-500 with an unbalanced 5CHN 25/30 drive diesel engine, taking into account the influence of thrust on-board, bow and stern vibration isolators. Calculations of SDGA vibration isolation become more complicated if the drive diesel is unbalanced, and the thrust vibration isolators relative to the load-bearing frame are installed without gaps. The purpose of the presented methodology is to study the effect of persistent vibration isolators on the effectiveness of vibration isolation of the general suspention system and substantiate the need to calculate the depreciation of the SDGA taking into account the influence of persistent vibration isolators. The vibration isolation calculation methodology provides for the presentation of: schemes of the support and thrust suspention systems with the corresponding components; initial data; the sequence of vibration isolation calculations according to two options – without and taking into account the influence of thrust vibration isolators and the construction of frequency diagrams. The frequencies of free vibrations, without taking into account the influence of persistent vibration isolators, are 30–54% less than the values of the corresponding frequencies, taking into account the influence of persistent vibration isolators, which indicates the expediency of calculating the vibration isolation of the unit, taking into account the influence of persistent vibration isolators.

Повышение безопасности судов в штормовых условиях при наличии зарываемости носовой оконечности, когда может произойти её захват волной, сопряжено с необходимостью определения гидродинамических сил и моментов, возникающих в носовой оконечности судна и оценки влияния на их величину конструктивных элементов носовой части судна, в частности, фальшборта. В настоящей работе для исследования динамики взаимодействия носовой оконечности судна с внешней средой использовался метод SPH. Выполнена оценка гидродинамических сил, действующих на носовую оконечность в направлении обтекания и в поперечном направлении, показавшая, что их величина может быть весьма существенной и представлять опасность с точки зрения обеспечения безопасности мореплавания. Исследовано изменение гидродинамических сил и моментов, действующих на носовую оконечность, в зависимости от угла крена судна а также геометрических характеристик фальшборта. Показано существенное влияние главных размерений и условий загрузки судна, а также фальшборта и его характеристик, на величину гидродинамических сил и кренящих моментов, действующих на носовую оконечность судна в условиях ее зарываемости в волну.
Improving the safety of ships in stormy conditions in the presence of burrowing of the bow, when it can be captured by a wave, is associated with the need to determine the hydrodynamic forces and moments that arise in the bow of the ship and assess the impact on their magnitude of the structural elements of the bow of the ship, in particular, the bulwark. In this work, the SPH method was used to study the dynamics of the interaction of the bow of the ship with the external environment. An assessment of the hydrodynamic forces acting on the bow in the flow direction and in the transverse direction has been carried out, showing that their magnitude can be very significant and pose a danger from the point of view of ensuring the safety of navigation. The change in hydrodynamic forces and moments acting on the bow is investigated, depending on the roll angle of the vessel and the geometric characteristics of the bulwark. A significant influence of the main dimensions and loading conditions of the vessel, as well as the bulwark and its characteristics, on the magnitude of hydrodynamic forces and heeling moments acting on the bow end of the vessel in the conditions of its burrowing into a wave.
