La protección contra el despido y otras consecuencias desfavorables
Authors: Dormido Abril Julia
Published: May 2022

La Directiva (UE) 2019/1158 establece la obligación de que los Estados miembros adopten las medidas que sean necesarias para prohibir el despido y cualquier preparación de éste cuando los trabajadores quieran hacer efectivos los derechos reconocidos en los diferentes ordenamientos jurídicos con relación a la conciliación de la vida laboral y familiar. Se trata de establecer mecanismos de protección específicos contra las represaliasque pueda emprender la empresa desde el momento en el que se solicitan o se disfrutan por parte de cualquiera de los progenitores los permisos relativos al ejercicio corresponsable de los derechos de la vida familiar y laboral.

Sin duda, el reparto equitativo de las cargas familiares es un instrumento que fomenta la igualdad real y efectiva entre ambos géneros, por lo que, resulta imprescindible que se establezcan en la legislación nacional cuáles son las consecuencias que tendrá que asumir laempresa que haya actuado de forma ilícita. Nos referimos, por tanto, a la imposición de unas sanciones que deberán tener una entidad suficiente como para ser efectivas y disuasorias, de manera que la parte empleadora no trate de despedir a las trabajadoras y los trabajadoresque pretendan solicitar un permiso de conciliación para atender a un familiar que dependa de ellos o necesite de cuidados, por cualquiera de las circunstancias especialmente protegidas en la normativa europea.
Estatuto de refugiada por motivos de género, blindaje de fronteras y desafíos actuales en la UE
Authors: Yela Uceda Mercedes
Published: May 2022

En los últimos tiempos se han producido numerosas llegadas a la Unión Europea para solicitar refugio, desde el año 2015 estamos viviendo una crisis humanitaria inigualable. A pesar de que el número de solicitudes de refugio se ha reducido, las necesidades son mayores y los campos de refugiados se encuentran en una situación de vulnerabilidad extrema. La pandemia de la COVID-19 ha bloqueado y suspendido la adquisición de los procedimientos de protección internacional, vulnerando los derechos de los refugiados y en particular de las mujeres. La situación de las mujeres solicitantes de refugio y el acceso al estatuto de protección por motivos de género, a la luz de los principios de la Convención sobre el Estatuto de los Refugiados de1951, en tiempos de crisis sanitaria deben ser estudiadas a través de una metodología descriptiva y documental. Al mismo tiempo la respuesta de la UE a las llegadas de refugiados requiere de un estudio en profundidad. El incumplimiento de cuotas, la falta del principio de solidaridad, la ausencia del principio de reparto de cargas propician, sin duda, la falta de protección a los solicitantes de refugio a pesar de que cumplan los requisitos establecidos en la normativa internacional para poder adquirir la protección como refugiadas. Se realizará un análisis desde el punto de vista criminológico-penal donde poder identificar las necesidades específicas de las mujeres, las consecuencias dañinas de los hechos traumáticos que viven las refugiadas y los riesgos que atraviesan hasta llegar al Estado de acogida.

Bovine papillomavirus (BPV) induces benign tumors of cutaneous or mucosa epithelia, called papillomas or warts in cattle and generally regress without eliciting any serious clinical problems in the host, but occasionally persist and provide the focus for malignant transformation to squamous cell carcinoma. This has a negative implication in beef and hide industry. There is paucity of information on the comparative pathology and molecular detection of BPVs in different breeds of nomadic cattle. Consequently, 340 nomadic cattle grazing in Plateau state Nigeria were screened clinically for papillomatosis followed by histopathology. Lesion consistent with papillomatosis were further investigated using immunohistochemistry (IHC), Polymerase chain reaction (PCR) and electron microscopy. Twenty cattle (0.06%) of Friesian, Zebu, Muturu and White Fulani breeds had cutaneous papilloma and skin lesions of the head, neck, shoulders, legs, dorsum, lower abdomen and scrotum. However, only 16 (0.05%) cattle skin biopsy samples were consistent with papillomatosis histopathologically revealing varying degrees of hyperplastic epidermis with acanthosis and orthokeratotic hyperkeratosis. Nuclei in the granular layer of the epidermis were IHC positive for Bovine papillomavirus type I antigen while skin biopsy was BPV-1 E5 oncoprotein gene positive by PCR. Electron microscopy revealed ultrastructural changes consistent with Bovine papillomavirus infection. The distribution and severity of lesion varied in different breeds of nomadic cattle. The detection, diagnosis and characterization of papillomavirus in these cattle enabled the development of autogenous vaccine to immunized cattle. This study highlighted the comparative pathology and molecular characterization of BPVs in different breeds of nomadic cattle, which hitherto was lacking.

Published: May 2022

Lithium oxides are the most promising cathode candidates for high-performance lithium-ion batteries (LIBs), owing to their high theoretical capacity and average working voltage, which are conducive to achieving the ultimate goal of upgrading energy density. By raising the upper limit of the cutoff voltage, we may be able to further improve both the practical capacity and average voltage of lithium oxide cathodes. Unfortunately, the high-voltage operation of these cathodes results in significant challenges, namely, reduced surface structural stability and interfacial stability with electrolytes, thus degrading the electrochemical performance. Accordingly, surface/interface modification strategies, including surface coating, electrolyte regulation, binder design, and special surface treatments, are systematically summarized and comprehensively analyzed for high-voltage lithium oxide cathode materials in this review. Furthermore, the corresponding modification mechanisms are discussed in detail to better grasp the internal mechanisms for the enhanced electrochemical performance. Based on recent progress, we further propose predictable development directions for high-performance LIBs in future practical applications. This review provides new insights into various high-voltage lithium oxide cathodes and their universal surface/interface modification strategies towards advanced next-generation LIBs with high energy and power density and long cycle life.

Authors: Boin Christian , Lei Lei , Yang Simon X.
Published: May 2022

Since 2016 federated learning (FL) has been an evolving topic of discussion in the artificial intelligence (AI) research community. Applications of FL led to the development and study of federated reinforcement learning (FRL). Few works exist on the topic of FRL applied to autonomous vehicle (AV) platoons. In addition, most FRL works choose a single aggregation method (usually weight or gradient aggregation). We explore FRL's effectiveness as a means to improve AV platooning by designing and implementing an FRL framework atop a custom AV platoon environment. The application of FRL in AV platooning is studied under two scenarios: (1) Inter-platoon FRL (Inter-FRL) where FRL is applied to AVs across different platoons; (2) Intra-platoon FRL (Intra-FRL) where FRL is applied to AVs within a single platoon. Both Inter-FRL and Intra-FRL are applied to a custom AV platooning environment using both gradient and weight aggregation to observe the performance effects FRL can have on AV platoons relative to an AV platooning environment trained without FRL. It is concluded that Intra-FRL using weight aggregation (Intra-FRLWA) provides the best performance for controlling an AV platoon. In addition, we found that weight aggregation in FRL for AV platooning provides increases in performance relative to gradient aggregation. Finally, a performance analysis is conducted for Intra-FRLWA versus a platooning environment without FRL for platoons of length 3, 4 and 5 vehicles. It is concluded that Intra-FRLWA largely out-performs the platooning environment that is trained without FRL.

Authors: Herliwati Herliwati , Rahman Mijani
Published: May 2022

Decreasing of water quality and exceeding the loading capacity of water pollution are the main causes of the high mortality of cage aquaculture  along the river in South Kalimantan province. The research objective was to analyze the river water quality profile, and to evaluate the  loading capacity of water pollution around the cage aquaculture. The observations were made at 3 points (upstream, middle and downstream) along Harus river where is the center for the development of cage aquaculture in Banua Lawas District, Tabalong Regency. On each of these points, measurement of physico-chemical parameters of water and flow rates were carried out. Measurement and data collection were performed twice with intervals between measurements for 30 days. Water quality parameters analyzed were water temperature, pH, TSS, NH3-N, NO3-N, PO4-P, BOD, COD, and DO. Based the eight water quality parameters measured, there were three parameters that tend to exceeding the loading capacity of water pollution on all the river segments, namely PO4-P, (at middle = 16 kg day-1, and downstream = 459 kg day-1),  BOD (at upstream = 301 kg day-1, middle = 547 kg day-1, and downstream = 2,086 kg day-1) and COD (at upstream = 521 kg day-1, middle = 380 kg day-1 and downstream = 1,249 kg day-1). Exceeding the load capacity of BOD and COD were prone to cause depletion of DO in the river in which can potentially cause massive fish mortality.

One of the local fish resources in South Kalimantan is Anabas testudineus fish. It is known that A. testudineus fish mucus has antibacterial activity, but this study only looked at the inhibitory of fish mucus. Until now, there has been no test for the Minimum Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) of A. testudineus fish mucus. One of the bacteria that infect wounds is S. aureus. MIC and MBC obtained are used as a reference in determining the concentration of A. testedineus fish mucus gel for wound healing activity test. This study aimed to determine the MIC and MBC of A. testudineus fish mucus in S. aureus and analyze the wound healing activity of A. testudineus fish mucus. MIC and MBC using turbidity test. In this research, 3 fish mucus gel formulas are made. Wound healing activity test on Wistar rats that were given wound initiation with a diameter of 1.5 cm, and were observed after 7 days of treatment. Observations were made covering the area of the wound using image J and histology of rat skin. The results showed that MIC and MBC of A. testudineus fish mucus were 21.875%. Fish mucus gel formula was made into concentrations of 10%, 20% and 40%. The results of the wound healing test showed that giving A. testudineus fish mucus caused a decrease in the area of the wound but based on histology of the skin, the inflammation still occurred.

Published: May 2022

Peatland is a unique, marginal, and fragile ecosystem. Its utilization must be based on thorough research and planning, and it needs supports from everyone. Yards, fields, and gardens are the forms that the community generally uses to utilize peatlands. This research aims to assess community's activities in the peatlands as their source of living and income. This research was conducted in Indonesia, specifically in the Province of South Kalimantan within an area with the biggest peatland contour. Descriptive data research was analyzed using thematic, socio-economic, and SWOT analysis. Research finding showed that farming is the suitable source of livelihood in the peatlands, besides plantation and other fields. The highest income from non-land activities on the peatlands are from entrepreneurship, physical service, and animal husbandry. People's general livelihood are as farmers whose prior commodity is with bigger average income than the province minimum wage per month. This is expected to describe that income from peatlands can make the ends meet of the community. This can also increase farmer's knowledge in cultivating their lands, the choice of plant type that is suitable with biophysical conditions of the peatlands. To work on the limit of the community's knowledge, activities and solutions from the experts on how to deal with farmer's problems in cultivating peatlands, are needed. Agroforestry technique is very suitable to analyze the source of livelihood. As forms to reserve lands in a farming world, the use of husk charcoal is also suggested. It has abundant benefits. It is often used for soil loosening, even for composting. Farmers make use of it for making compost, bokashi, Takakura, planting media, and seedbed media.

Published: May 2022

Research on carbon storage is currently in the world spotlight along with the increasing greenhouse effect. Mangroves as one of the ecosystems play a role in blue carbon which can store more carbon than terrestrial forests. Mangroves absorb more carbon than any other forest ecosystem. This is because mangroves are included in wetlands that have the ability to store carbon when the land remains wet. An in-depth discussion was carried out by integrating various literatures on mangroves from 2011–2021 to enrich the information for this research. Mangrove area in West Kalimantan in the period 2011 - 2021 has an area of about 256,586.80 Ha which is dominated by species Brugueira spp., Rhizophora spp., Sonneratia alba, Avicennia spp. Nypa fruticans, Excoecaria agallocha, Xylocarpus moluccensis and Acrostichum speciosum. Human activities, abrasion and sedimentation have caused a decrease in the area of mangrove ecosystems in West Kalimantan. An increase in temperature has a global impact on life on the earth's surface and the environmental conditions of mangroves. The decrease in micropopulation and aboveground biomass causes a decrease in infauna species and biomass, affects nutrient cycles, destroys nurseries, and reduces mangrove ecosystem services. The results show that mangrove carbon storage in the period 2011 - 2021 is 628.10 tons C.ha-1 which has an economic valuation of 3,410.50 US$. Efforts to mitigate global warming and trade in mangroves can be carried out through community-based restoration, restoration of forest plantings, integrated coastal ecosystem rehabilitation, and economic approaches.

Increasing rice production with the use of high-yielding varieties and proper plant spacing must consider the environmental aspect. Organic agriculture is an effort to accelerate the cultivation techniques with environmental health, in addition, the research site is a tidal land that has been cultivating rice organically since 2009. The research aimed to study the growth and yield of superior varieties and new plant type of rice on various cropping systems in tidal land. The research was carried out at the Laboratory of Center for Protection of Food Crops and Horticulture, Sungai Tabuk District, Banjar Regency. The experimental design was a split-plot with three replications.  The main plot were s1 = Tile System, s2 = Legowo System 2:1, s3 = Legowo System 8:1 cropping systems and subplots were  v1= Ciherang, v2= Mekongga, v3= IPB Batola 6R, v4= IPB 3S varieties. The experimental unit was a plot with a size of 10 m2. The results showed that there was no interaction between cropping systems and rice varieties. The main plot of cropping system Legowo 2:1 showed the best percentage of filled grain per panicle (87%). Sub-plot of rice varieties affected some plant growth and yield variables. Superior varieties Ciherang and Mekongga had more tillers and panicles per clump. The new plant type varieties showed a greater number of grains per panicle and tended to have a better percentage of filled grains per panicle and a weight of 1,000 grains.

The objective of this study is to empirically investigate the impacts of ownerships (managerial ownership and institutional ownership) and control (number of independent commissioners, frequency of audit committee meeting, and audit committee competence) on Internet Financial Reporting (IFR). This study was conducted on manufacturing companies listed at the Indonesian Stock Exchange (BEI) in 2015-2019. This study used secondary data, namely annual financial statements which were accessed through the companies’ websites. The firm years counted 200 with 40 companies and 5 years of research duration. The dependent variable is IFR which analyzed the contents of the websites with the maximum score of 54. The independent variables are managerial ownership, institutional ownership, number of independent commissioners, frequency of audit committee meeting, and competence of audit committee. The results show that institutional ownership, frequency of audit committee meeting, and audit committee competence have significantly and positively influences on IFR. However, institutional ownership negatively affects IFR. Meanwhile, number of independent commissioners does not influence internet financial reporting.

Published: May 2022

The occurrence and intensity of the detonation phenomenon at spark-ignition (SI) engine conditions is investigated, with the objective to successfully predict super-knock and to elucidate the effect of kinetics and transport at the ignition front. The computational singular perturbation (CSP) framework is employed in order to investigate the chemical and transport mechanisms of deflagration and detonation cases in the context of 2D high-fidelity numerical simulations. The analysis revealed that the detonation development is characterized by: (i) stronger explosive dynamics and (ii) enhanced role of convection. The role of chemistry was also found to be pivotal to the detonation development which explained the stronger explosive character of the system, the latter being an indication of the system's reactivity. The role of convection was found to be enhanced at the edge of the detonating front, thereby suggesting that it is the result and not the cause of the detonation onset. Moreover, the increased contribution of convection was found to be related mainly to heat convection. Remarkably, the detonation front was mainly characterized by dissipative and not explosive dynamics. Finally, diffusion was found to have negligible role to both examined cases.

Published: May 2022

The Drosophila imaginal disc has been an excellent model for the study of developmental gene regulation. In particular, long non-coding RNAs (lncRNAs) have gained widespread attention in recent years due to their important role in gene regulation. Their specific spatiotemporal expressions further support their role in developmental processes and diseases. In this study, we explored the role of a novel lncRNA in Drosophila leg development by dissecting and dissociating w1118 third-instar larval third leg (L3) discs into single cells and single nuclei, and performing single-cell RNA-sequencing (scRNA-seq) and single-cell assays for transposase-accessible chromatin (scATAC-seq). Single-cell transcriptomics analysis of the L3 discs across three developmental timepoints revealed different cell types and identified lncRNA:CR33938 as a distal specific gene with high expression in late development. This was further validated by fluorescence in-situ hybridization (FISH). The scATAC-seq results reproduced the single-cell transcriptomics landscape and elucidated the distal cell functions at different timepoints. Furthermore, overexpression of lncRNA:CR33938 in the S2 cell line increased the expression of leg development genes, further confirming its important role in development.

Published: May 2022

Quantum cell automata (QCA) is a nanotechnology that uses a transistor-free structure to design digital circuits and overcome the limitations listed for CMOS circuits. The computing circuits that make up the bulk of computers can be designed and using this technology. Subtractors are a big part of computational circuits. This research deals with the design of a subtractor that due to the innovation in the design of this circuit and the novel arrangement of quantum cells of its kind has caused the number of cells used in the design of the circuit to reach its lowest value compared to previously designed circuits. The size of the circuit as well as the loss power are minimized compared to the circuits designed by the subtractors. Another trait clears of this circuit compared to many previous designs is its single-layer design, which reduces latency and noise in the output waveform. The circuit designed by the QCADesigner simulator is tested and simulated inadition the results are displayed in the simulated waveform. Also, the results of calculations for power dissipation in each QCA cell were evaluated by QCAPro software, which is a powerful tool for estimating power loss simulation. It has less implementation and level (single layer) than Previous designs.
Assessing the Impact of Features on Probabilistic Forecasting of Photovoltaic Power Generation
Authors: Yamamoto Hiroki , Kondoh Junji , Kodaira Daisuke
Published: May 2022

Photovoltaic power generation has high variability and uncertainty because it is affected by uncertain factors such as weather conditions. Therefore, probabilistic forecasting is useful for optimal operation and risk hedging in power systems with large amounts of photovoltaic power generation. However, deterministic forecasting is the mainstay of photovoltaic generation forecasting; there are few studies on probabilistic forecasting and feature selection from weather or time-oriented features in such forecasting. In this study, prediction intervals were generated by the lower upper bound estimation using neural networks with two outputs to make probabilistic predictions. The objective was to improve prediction interval coverage probability (PICP), mean prediction interval width (MPIW), and loss, which is the integration of these two metrics, by removing unnecessary features through feature selection. When features with high gain were selected by random forests (RF), in the forecast of 14.7-kW PV systems, loss improved by 1.57 kW, PICP by 0.057, and MPIW by 0.12 kW on average over two weeks compared to the case where all features were used without feature selection. Therefore, the low gain features from RF act as noise in LUBE and reduce the prediction accuracy.

The effective integration of aerial remote sensing data and ground multi-source data has always been one of the difficulties of quantitative remote sensing. A new monitoring mode is designed which installs the hyperspectral imager on the UAV and places a buoy spectrometer on the river. Water samples are collected simultaneously to obtain in situ assay data of total phosphorus, total nitrogen, COD, turbidity and chlorophyll during data collection. The cross correlogram spectral matching (CCSM) algorithm is used to match the data of the buoy spectrometer with the UAV spectral data to reduce the UAV data noise significantly. An absorption characteristics recognition algorithm (ACR) is designed to realize a new method for comparing UAV data with laboratory data. This method takes into account the spectral characteristics and the correlation characteristics of test data synchronously. It is concluded that the most accurate water quality parameters can be calculated by using the regression method under five scales after the regression tests of multiple linear regression method (MLR), support vector machine method (SVM) and neural network (NN) method. This new working mode of integrating spectral imager data with point spectrometer data will become a trend in water quality monitoring.

Published: May 2022

Artificial roughness applied to the Solar Air Heater (SAH)’s absorber plate is a popular technique to increase its total-thermal efficiency (η_(t-th)). In this paper, the influence of geometrical parameters of V-down ribs attached below the corrugated absorbing plate of SAH on the η_(t-th) has been examined. The impacts of key roughness parameters, including relative pitch p⁄e (6-12), relative height e⁄D (0.019-0.043), angle of attack α (30°-75°), and Re (1000-20000), are examined under real weather conditions. The SAH η_(t-th) roughened by V-down ribs is predicted using an in-house developed conjugate heat transfer numerical model. It has been shown that the maximum SAH η_(t-th) is 78.8%, predicted under steady-state conditions of Re = 20000, solar irradiance G =1000 W/m2, p/e = 8, e/D = 0.043, and angle =60. That is 15.7% more efficient than that of the default smooth surface. Under real weather condition, the η_(t-th) of the roughened SAH with single and double glass covers are 17.7% and 20.1%, respectively, higher than those of smooth SAH.

Published: May 2022

The authors have revised the circularity of materials, which is important to stimulate circular activity processes. The theoretical part starts with describing the characteristics of the circular activity and the comparison of circular and linear systems in terms of recycling. Later on, the authors examined key elements important for the circularity and the results of an examination of various sectors. The authors formed a correlation matrix and used a dynamic regression model to identify the circular material use rate. The authors suggested a three-level methodology, using it provided a dynamic regression model which could be applied for forecasting the size of circular material use rate in European Union countries. The results show that private investments into recycling and the recycling of electronic waste and the recycling of other municipal waste categories are important in seeking to increase the usage rate of circular materials.

Published: May 2022

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Its treatment includes antiarrhythmic drugs (AADs) to modulate the function of cardiac ion channels. However, AADs have been limited by proarrhythmic effects, non-cardiovascular toxicities as well as often modest antiarrhythmic efficacy. Theoretical models showed that combined blockade of Nav1.5 (and its current INa) and Kv1.5 (and its current, IKur) ion channels yield a synergistic anti-arrhythmic effect without effect on ventricles. We focused on Kv1.5 and Nav1.5 to search for structural similarities in their binding site (BS) for flecainide (a common blocker and widely prescribed AAD), as a first step for prospective rational multi-target directed ligand (MTDL) design strategies. We presented a computational workflow for flecainide BS comparison in a flecainide-Kv1.5 docking model and a solved structure of flecainide-Nav1.5 complex. The workflow includes docking, molecular dynamics, BS characterization and pattern matching. We identified a common structural pattern in flecainide BS for these channels. The latter belongs to the inner cavity and consist of a hydrophobic patch and a polar region, involving residues from S6 helix and P-loop. Since the rational MTDL design for AF is still incipient, our findings could advance multi-target atrial-selective strategies for AF treatment.

Published: May 2022

African swine fever (ASF) is a notifiable viral disease of domestic and wild suids. Despite intensive re-search efforts, the pathogenesis of the disease is still far from being understood. Analysis of biomarkers in different body fluids may supplement traditional pathogenesis studies. As reliable protocols are often es-tablished in laboratories with lower biosafety, reliable inactivation of samples is crucial. The objective of this study was to find a procedure that inactivates the virus while preserving the biomarkers for down-stream analyses. To this means, three different inactivation protocols were employed, namely Tergitol-type NP-40 (NP-40) and polyoxyethylene-p-t-octylphenol (Triton X-100), respectively, and one with 95 °C heating. It could be demonstrated that all samples treated with 0.5% (v/v) concentration of both deter-gents showed absence of virus infectivity. The same was true for heated samples. However, heated serum was not suitable for analyses. Next, the treatment impact on biomarker readouts was assessed. While all protocols had an impact on the detection of biomarkers, correlation was retained. Especially NP-40 could be the desired detergent for more accurate measurements while achieving efficient virus inactivation. Based on these studies, samples can be reliably inactivated for most biomarker analyses and thus broader interdisciplinary cooperation is possible.

We set a feasible method to produce tailored collagen scaffolds and analyzed its potential for corneal engineering. Collagen-vitrigel membranes (CVM) were produced with a 1:1 ratio of Dulbecco’s Modified Eagle’s medium (DMEM), 1% antibiotics and 8% fetal bovine serum, and 5mg/mL collagen type I. Three volumes of collagen were used: 1X (2.8 L/mm2 of collagen), 2X, and 3X. Vitrification was done at 40% relative humidity (RH), 40° C, and 30 rpm using a matryoshka system set with a shaking-oven and a desiccator with a saturated K2CO3 solution. The CVM was characterized for width, microstructure, transparency, and biocompatibility using NIH3T3 cells. Surgical manipulation was assessed in an ex vivo corneal model. Constructs of corneal endothelial cells (CECs) and 2X-CVM were transplanted into five 18-month-old White New Zealand rabbits. CVM exhibited homogeneous surface and laminar organization. Membrane width increased with gel volume from 3.65µm to 7.2µm. 1X and 2X-CVM exhibited a 99% transmittance. NIH3T3 cells concentration increased 3-fold within 48 h with no significant difference among the 3 CVM (p = 0.323). The 2X-CVM was surgically manipulable. Transplantation of corneal endothelial cells (CECs) seeded over 2X-CVM restored corneal endothelium. The matrioshka system is a feasible method that yields CVM suitable for corneal engineering.

Приводится обзор моделей относительного движения нескольких спутников в
группе, использующих для описания положения относительные координаты. Сравнивается точность декартовых и криволинейных координат в линейных моделях
движения. Показано, что использование криволинейных координат позволяет существенно улучшить точность описания относительного движения, особенно на
больших размерах относительных орбит. Рассмотрение криволинейных координат
приводится на примере моделей движения Хилла-Клохесси-Уилтшира и Швайгхарта-Седвика.
