Internet of Spacecraft for Multi-planetary Defense and Prosperity
Authors: Huo Yiming
Published: May 2022

Recent years have seen unprecedentedly fast-growing prosperity in the commercial space industry. Several privately funded aerospace manufacturers, such as Space Exploration Technologies Corporation (SpaceX) and Blue Origin have innovated what we used to know about this capital-intense industry and gradually reshaped the future of human civilization. As private spaceflight and multi-planetary immigration gradually become realities from science fiction (sci-fi) and theory, both opportunities and challenges are presented. In this article, a review of the progress in space exploration and the underlying space technologies is firstly provided. For the next, a revisit and a prediction are paid and made to the K-Pg extinction event, the Chelyabinsk event, extra-terrestrialization, terraforming, planetary defense, including the emerging near-Earth object (NEO) observation and NEO impact avoidance technologies and strategies. Furthermore, a framework of the Solar Communication and Defense Networks (SCADN) with advanced algorithms and high efficacy is proposed to enable an internet of distributed deep-space sensing, communications, and defense to cope with disastrous incidents such as asteroid/comet impacts. Furthermore, the perspectives on the legislation, management, and supervision of founding the proposed SCADN are also discussed in depth.
A Risk Reducing Fleet Monitor for Automated Vehicles Based on Extreme Value Theory
Authors: Åsljung Daniel , Zandén Carl , Fredriksson Jonas
Published: May 2022

This paper proposes a proactive fleet monitoring approach for automated vehicles (AVs) based on Extreme Value Theory (EVT) to reduce the accident risk during first deployment and software updates. By performing sequential statistical tests on threat metrics measured in an AV fleet, the monitor can be used to quickly identify and abort operations if the AVs do not meet the required level of safety. To evaluate the proposed monitoring approach, it is studied in a fictive deployment case using two different threat metrics, one predictive and one retrospective. The evaluation showed that a significant risk reduction is achievable when using the EVT fleet monitor compared to reactive fleet monitoring. Moreover, using a predictive threat metric reduces the risk of accidents dramatically. However, it has the drawback of frequently aborting operations unless the systems are significantly better than required. On the other hand, a retrospective threat metric was a more balanced alternative that could substantially reduce risk without being overly conservative. In summation, the EVT fleet monitoring is a promising complementary approach to traditional validation to minimize the risk and abort operations of sub-performing new deployments well before any accidents are caused.
Paul M. Sweezy
Authors: Cecchi Amos
Published: May 2022

Paul M. Sweezy (New York, 1910-2004) was a co-founder and, for over half a century, co-editor of Monthly Review. At the basis of his theoretical thought there is a Marxian approach, open and creative, and an attention to high elaboration of the twentieth century – Hilferding and Veblen, Schumpeter and Keynes, Kalecki and Steindl. With The Theory of Capitalist Development (1942) and Monopoly Capital (1966, written with Baran), he was a reference point on a global level. Monopoly capitalism is marked by an organic tendency to stagnation. Antagonistic factors can, in some way, counteract it: waste, with induced consumption and armaments, epoch-making innovations and wars. In the Sweezian reflection of the last quarter of the twentieth century – also in dialogue with Minsky – the systemic trend is particularly counteracted by the large indebtedness and finance explosion. However, finance becoming autonomous and placing itself at the center of the system increases its instability and unsustainability and exposure to the crisis.

Authors: Tripathy Tridibesh , Prusty Umakant , Nayak Chitamani
Published: May 2022

Reading a heading in the Hindustan Times supplement on 10th May (Mother’s day) which wrote ‘Mum is not a good word’ was surprising & when delved in to the article, it was about mothers who went through postnatal depression & have narrated their painful experiences & how they came out of the situation. The current article looks into the aspects of mental disorders during postnatal period out of which postnatal depression is one of the disorders. The article looks into the brief history of public health programs on mental health in India & the emergence of maternal mental health as an issue. It moves on to the current situation on postnatal disorders in India & the role of Homoeopathy to deal with these disorders therapeutically as a component of Ministry of AYUSH. The article suggests the integration of medical pluralism in mental health through inclusion of Homoeopathy in the gamete of mental health. As each & every drug in Homoeopathy is only proved on human beings, all the drugs have a mental component as it is only human beings who can express their physical & mental symptoms during proving of the drugs as per the guidelines set by the Homoeopathic research councils of each nation. In India, Central Council for Research in Homoeopathy, an autonomous body under the ministry of AYUSH lays out such guidelines. The article gains more relevance during the current COVID 19 crisis which has precipitated the stress levels & the mothers who have delivered since March 2020 are more prone to mental disorders during their postnatal stage.

Authors: Dzingirayi Prince , Moyo Grace
Published: May 2022

Globally, academic zeal had been put on hold by the outbreak of COVID-19 pandemic. The coronavirus lockdown which lead to the closure of all learning institutions in Zimbabwe has caused traditional university students to indulge in health risk behaviours. The research findings revealed that some of the health risk behaviour have short term or long term effects. The lockdown led university students to sexual abuse, alcohol abuse, reluctant at home, social media addiction, drug abuse, excessive sleeping and eating habits. These health risk behaviour causes physical and psychological effects to traditional university students. This study is conducted with an aim of exploring the health risk behaviours experienced by traditional university students during the implementation of COVID-19 restrictive measures in Matabeleland Province. The phenomenological research design was used to study individuals in their natural setting and the population in the study was traditional students from National University of Science (NUST) and Technology, Zimbabwe Open University (ZOU) and Lupane State University of Matabeleland region. The convenience and purposive sampling was used to select the participants and data was analyzed using thematic content analysis. Data was collected through an open ended interview question on social media platforms. The COVID-19 lockdown have caused more harm to traditional university students as they were cornered to behave in unexpected behaviours which threatens their future.

Para testicular rhabdomyosarcoma is a rare malignant tumour, which usually presents as a painless mass in the scrotum or groin. A case of paratesticular embryonal rhabdomyosarcoma in a 16-year-old male, with a history of left testicular ectopia treated with orchiopexy, is being reported here who presented with chronic scrotal swelling. Paratesticular rhabdomyosarcoma is a rare non germ cell tumour of scrotal sac in children and young adult/teens which can invade testis at presentation. Embryonal variant is the most common type. 40% cases can have metastasis to retroperitoneal lymph node. Diagnosis can be done on high degree of clinical suspicion coupled with biopsy and immunohistochemistry. Multimodality approach of treatment is often beneficial for patients.

Most of the traditional recommendation algorithm models are recommended based on the user's own historical preferences, although it can recommend POI for users to a certain extent. But in real life, people are more willing to ask their friends what they think when they have a difficult decision. Therefore, a word2vec-based social relationship point of interest recommendation model (W-SimTru) is proposed, which combines the similarity of friends based on cosine similarity with the friend trust recommendation algorithm based on TF-IDF to improve the model recommendation effect. In addition, before modeling the similarity of users, word2vec is used to process the user's historical check-in behavior to solve the problem of inaccurate recommendation due to sparse check-in data. Finally, experiments are carried out on three datasets of Los Angeles, Washington and NYC in Gowalla, and the experimental results show that the proposed W-SimTru recommendation algorithm outperforms the algorithms of the three comparative experiments.
Erasing Boundaries: Masculinities, Sexual Minorities, and Employment Discrimination
Authors: McGinley Ann
Published: May 2022

This Article analyzes the application of employment discrimination law to sexual minorities-lesbians, gays, bisexuals, transgender and intersex individuals. It evaluates Title VII and state anti-discrimination laws' treatment of these individuals, and is the first article to use masculinities research, theoretical and empirical, to explain employment discrimination against sexual minorities.

While the Article concludes that new legislation would further the interests of sexual minorities, it posits that it is neither necessary nor sufficient to solving the employment discrimination problems of sexual minorities. A major problem lies in the courts' binary view of sex and gender, a view that identifies men and women as polar opposites, and that sees gender as naturally flowing from biological sex. Without courts' understanding that our current binary concept of gender may be socially constructed and artificially rigid rather than a natural result of biology, even new legislation may fail to protect the workers it seeks to protect.

The Article demonstrates that research on masculinities can help courts better understand sexual minorities and the motivations of those who discriminate against them in the workplace. It concludes that even in the absence of new legislation, a proper interpretation of Title VII's sex discrimination provision would protect sexual minorities from discrimination and would provide reasonable accommodation to allow sexual minorities to live and work with dignity and security. With an understanding of sexual minorities and the reasons why discrimination occurs, Title VII's prohibition of discrimination "because of sex" should be sufficient to grant sexual minorities workplace rights.
The French Huissier as a Model for U.S. Civil Procedure Reform
Authors: Emerson Robert
Published: May 2022

Huissiers de justice serve multiple roles in the French legal system. One is that of a court officer who compiles dossiers (reports). In that role, the huissier is d'audiencier (literally translated as "hearing" or "assisting") and works directly for the court system itself.

The huissier's report remains alien to the American lawyer, who is steeped in notions of procedure and "testimonialism" and in principles of fairness which appear ancient, but are rather modern dissimulations of law and equity's rich history in the American tradition. An important aspect of most legal processes, the collection of data in preparation for litigation is particularly marked by rhetorical differentiations and historical adaptations reflecting upon (actually, reinforcing) a cross-cultural dissonance that discourages both harmonization and legal experimentation between the two great Western legal cultures (Civil Law and common law).

The apparent discord between the two systems leads courts and commentators routinely to overestimate the disparity between the use of a French-styled investigative magistrate as opposed to the U.S. trial method. Despite the distinct nature of gathering evidence according to the French and U.S. traditions, the huissier is a type of figure found since the origin of the Western legal tradition. Vestiges remain in the United States, although American scholars and practitioners often overlook these manifestations (e.g., trustees and bailiffs). Still, the increasing complexity of commercial litigation, the harmonization of international civil procedure outside the United States, a growing corpus of international privacy standards, and a concern for the competitiveness of US. courts in attracting and inducing business development may cause re-examination of discovery rules, particularly the use of masters and investigative magistrates.

Realizing that the French system is reflected in U.S. law not only may aid in resolution of disputes where both French and US. courts might claim jurisdiction, and where issues of transnational discovery often become key to resolving conflicts of law, but further can function as a paradigm from which particular administrative functions in U.S. courts may be reformed and harmonized with international standards and with principles of efficiency.
DETECTION OF COVID FROM CHEST X-RAYS USING GAN
Authors: Unnikrishnan M  , Gontu Hemant Lakshman  , KhwairakpamBidyanandaSingh  , Sagar Pande
Published: May 2022

A great deal of lung-related infections including COVID-19 can be diagnosed in the early stages by examining the x-ray images. With the advancement in deep learning techniques, we can back this up to a great extent. For the formulation of such models, the complexion of the dataset used for them plays a key role. An inadequate dataset with an imbalanced class of samples adversely affects the performance of such models. Through this research work, we introduce an improved version of Auxiliary Classifier GAN (ACGAN) which is computationally much more efficient than the prior model for the augmentation of the dataset. The dataset used in this research work is highly imbalanced due to the lack of availability of covid-19 infected samples. The proposed GAN architecture has done a great job in solving this issue. After the augmentation phase, the dataset including the spawned new samples is fed into the detection network to evaluate the performance of the model. The use of pre-existing ImageNet weights and Adam as an optimizer helped to train the model at a quicker rate and the overall accuracy achieved was 95.67 and validation accuracy of 92.57 with a loss value reduced to 0.675.

Opinião dos Professores acerca do Desempenho dos Estudantes no Teste Cognitivo de Matemática no Saeb 9º do Ensino Fundamental
Authors: Machado da Costa Pereira Cátia Maria , De Jesus Teixeira Cristina , Eustáquio Moreira Geraldo
Published: May 2022

O estudo teve como objetivo investigar a percepção dos professores em relação às possíveis causas do baixo desempenho dos estudantes em Matemática 9º ano do Ensino Fundamental no teste do Saeb e a que elementos as causas estão relacionadas. Para a realização desta pesquisa, no período de março a junho de 2019, foram aplicados questionários com questões abertas a 33 professores de matemática dos anos finais do ensino fundamental do Distrito Federal. Os resultados indicaram que, na percepção dos professores, o baixo desempenho dos estudantes pode estar vinculado: às habilidades não desenvolvidas, ao desalinhamento entre a matriz do teste e organização do trabalho pedagógico: à desmotivação dos estudantes e aos ciclos de aprendizagem, visto que interferem no alcance dos objetivos de aprendizagem e, consequentemente, nos resultados do teste do Saeb. Conclusivamente, o estudo apontou a necessidade de mais reflexões acerca do tema avaliação, visto ainda haver discursos de professores com afirmativa que os estudantes só estudam quando pressionados pelas notas e pela reprovação.

Looks in search of the meaning of the human suffering
Authors: Salazar Garcia Abel Antonio
Published: May 2022

This text presents the terms pain and suffering that we often use interchangeably in our daily lives and how both involve, trap, disturb the individual; the suffering of the innocent is occurring in a very special way. So, to understand the effects of pain and suffering, we will mention the realms that encompass the human being, and how they perceive it. Suffering is perceived  in an existential reality that affects the individual when it occurs and continues in many cases leaving consequences in its wake, and what options are presented to us to face it or let ourselves be dragged by it.
Thyroiditis Should be Listed Among Adverse Effects of Covid-19 Vaccination
Authors: Mikhail Nasser
Published: May 2022

Background: Several cases of thyroiditis were recently reported in individuals vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing coronavirus disease 2019 (COVID-19).

Objective: To determine characteristics of thyroiditis occurring following SARS-CoV-2 vaccination.

Methods: PubMed search up to April 26, 2022. Search terms are thyroiditis, SARS-Cov-2, vaccine, COVID-19. Case reports, case series, review articles and pertinent in vitro studies in English, Spanish and French are reviewed.

Results: Review of literature revealed 97 patients with thyroiditis (71.3% women, age range 26-82 year-old) occurring following vaccination against SARS-CoV-2. Subjects reported from Turkey alone contributed to 50.5% of all cases. Seven cases (7.2%) presented with silent (painless) thyroiditis. Onset of thyroiditis symptoms ranged from 12 hours to 12 weeks after vaccination. In 74.2% of patients, these symptoms started between 3 to 15 days post-vaccination. The most frequently implicated vaccine was Pfizer-BioNTech vaccine (55.7% of cases) followed by CoronaVac (21.6%), Moderna (8.5%) and AstraZeneca (6.1%). Thyroiditis cases were equally triggered after the first and second vaccine dose. Personal and family history of thyroid diseases and autoimmune diseases were uncommon (<5%). Among 7 patients who were re-vaccinated, 5 did not have relapse of thyroiditis, whereas 2 subjects had recurrence or worsening of thyroiditis symptoms. Clinical picture and course of thyroiditis induced by the vaccine generally mimic those of non-vaccine-related classic thyroiditis. Mechanisms of thyroiditis after COVID-19 vaccination are unclear but there is evidence of genetic predisposition related to specific human leukocyte antigens (HLA) haplotypes. Glucocorticoid therapy of thyroiditis may virtually decrease COVID-19 vaccine immunogenicity.

Conclusion: Thyroiditis should be listed among adverse effects of COVID-19 vaccines to alert physicians and avoid misdiagnosis and unnecessary investigations. If possible, it may be better to avoid its treatment with glucocorticoids.

Authors: Sundoro Amin , Taufik Syahril
Published: May 2022

ABSTRACT

This study emphasizes the collapse of the offshore jacket platform structure model due to lateral loads, namely environmental loads with the help of USFOS computing software. The optimized platform structure model is the A model with 4 legs with a combination of X, V, Chevron, and K diagonal bracings. Then, step by step the bracing is progressively reduced until the first yield load level of the component is below 1 or the structure does not meet the design level criteria. The analysis used is nonlinear pushover from extreme storms. The platform model A was analyzed from 8 metocean directions and the next model was analyzed using the storm direction with the smallest RSR value from model A, namely the direction of 225°. The results of the analysis show changes in the global collapse mechanism, components that experience the first yield and changes in ductility. From the results of the scoring between the weight ratio of model A to the weight of the models with the redundancy value, the largest value obtained is the Platform E hybrid model with 4X bracing, 2 Chevrons, and 4 vertical diagonal models K with steel grade S315. The weight that can be optimized by the E Hybrid model from the A model is 101,801 kN, optimum 2,88% and redudancy factor reached 198.20%.

Keywords: Extreme storm, Collapse mechanism, Nonlinear Pushover, Redundancy, Ductility

FORMATION AND APPLICATION OF AN AGENT-ORIENTED MODEL IN THE MANAGEMENT OF THE OIL INDUSTRY OF THE REPUBLIC OF KAZAKHSTAN
Authors: Azieva G. , Alimagambetova A. , Turusbekova U.
Published: May 2022

Kazakhstan is one of the few countries in the world rich in oil, deservedly called“black gold” because it is the most important source of energy. The relevance of the studyof this paper is determined by the fact that the management of the oil industry affects notonly the management process itself, but also the social aspects of the implementation of thedevelopment strategy of the state as a whole. It is necessary to identify aspects of managementactivity and define criteria by which it is possible to calculate the effectiveness of managerialdecision-making in the analyzed industry. Agent models allow us to identify the main criteriafor the effectiveness of managerial decision-making and optimize social and economic costsfor their implementation within the framework of interdepartmental planning. The novelty ofthe research is determined by the fact that agent models are based not only on the associatedparameters of the management process, but also affect the possibility of planning currentactivities for a long period. The article shows that the formation of agent models should affectboth the aspect of the formation of matrices of complex managerial actions and calculationson the accounting of competencies in making managerial decisions. The practical significanceof the study is determined by the fact that the development of complex models based onagent forms allows expanding the use of forms of control over the industry by the state andother stakeholders. The implementation of a matrix form of management is proposed, takinginto account balanced industry indicators of management quality.

Authors: Toxanov S. , Abzhanova D. , Faizullin A.
Published: May 2022

Currently, there is an increase in demand for distance education programs,which actualizes the problems of organizing the educational process at universities usingthese technologies. The article highlights and describes the characteristic features andprospects of using the analysis of educational data in the information and educational portalof distance learning, in order to implement adaptive learning and learning in accordancewith dynamically formed individual trajectories. The task is to create a fundamentally newinformation system of the university using the results of the analysis of educational data. Oneof the functions of such a system is to extract knowledge from the data accumulated duringoperation. Creating own system of this type is an iterative and time-consuming process thatrequires preliminary research and step-by-step prototyping of modules. The novelty lies inthe fact that there is currently no methodology for developing such systems in Kazakhstan,so a number of experiments were conducted in order to collect data, select suitable methodsfor studying the collected data, and then interpret them. As a result of the experiment, theauthors identified the sources of educational data available for analysis in the informationenvironment of the university. The data of semester academic performance obtained from theToraighyrov University information system, data obtained as a result of independent work ofstudents and data obtained using specially developed Google-forms were taken as a basis. Aninformation and educational portal was created for the automated collection, processing andanalysis of educational data. Based on the study of students’ behavior, it becomes possibleto form recommendations for teachers to improve the content and structure, as well asrecommendations for the training of students. The data contained in the activity logs areexamined to obtain information, search for dependencies by filtering relevant logs, structuringinformation from them and providing data in a form convenient for analysis and drawingconclusions. The data of the main types of events generated as a result of recording useractions in the learning management system and scenarios for using the results of the analysisof these data are considered. The elements of the software implementation of this system aredescribed in detail, conclusions are made about the availability of the data sources used, andconclusions are drawn about the prospects for further development.

According to the state program “Informational Society 2030”, it is planned todevelop education on the basis of new progressive concepts of introducing the latestinformation technologies and scientific and methodological achievements into the educationalprocess. In order to achieve goals, it is necessary to implement mobilization and effective use ofstaff and property and technical resources of the university. It is possible if there is purposefulmodeling of the information and educational portal of the university.The choice and design of teaching technology are primarily determined by the type ofstudents’ competencies and the characteristics of the planned learning outcomes for eachlevel of competence (knowledge, skills, and experience). Constant improvement of EP contentand educational technologies as a key factor of education services quality is a vital demand.The article considers the issues of the concept of ontology, IDEF-technologies and, basedon the ontological model proposed in the article, the architecture of the database of theinformation and educational portal of the university is developed and classes and propertiesfor the implementation of this model are defined, and a functional model of the university inIDEF0 is developed, which covers all types of university activities, integrates all informationflows and forms a single information space.

We construct a certain reduction of the 2D Toda hierarchy and obtain a tau-symmetric Hamiltonian integrable hierarchy. This reduced integrable hierarchy controls the linear Hodge integrals in the way that one part of its flows yields the intermediate long wave hierarchy, and the remaining flows coincide with a certain limit of the flows of the fractional Volterra hierarchy which controls the special cubic Hodge integrals.

The links between the real and financial spheres are well recognized in the literature. However, under the conditions of sustainability, both the perception of the real and financial spheres, as well as the relations between them, change. The aim of this article is to show that sustainable finance has an impact on building a sustainable economy, and the model of sustainable finance increases the degree of adjustment of the financial sphere to the real economy. The research was conducted based on 86 articles. The methodology is based on log-linear models. As a result, it was proved that sustainable enterprises and finances are the factors that most frequently interact with other variables describing a sustainable economy. The study proposes the financial model for sustainable economy, this is the main novelty and contribution of the study. The original contribution of the study includes: the comprehensive analysis of the factors and relationships between sustainability, economy and finance; building a triple layered finance model for sustainable economy taking into account governance, society and environment from sustainable perspective; proposing the model of financing for the circular economy in terms of sustainability in terms of the process and defining the model of sustainable finance 4.0.
From Pericenter and Back: Full Debris Stream Evolution in Tidal Disruption Events
Authors: Bonnerot Clément , Pessah Martin E. , Lu Wenbin
Published: May 2022

When a star passes too close to a supermassive black hole, it gets disrupted by strong tidal forces. The stellar debris then evolves into an elongated stream of gas that partly falls back toward the black hole. We present an analytical model describing for the first time the full stream evolution during such a tidal disruption event (TDE). Our framework consists of dividing the stream into different sections of elliptical geometry, whose properties are independently evolved in their comoving frame under the tidal, pressure, and self-gravity forces. Through an explicit treatment of the tidal force and the inclusion of the gas angular momentum, we can accurately follow the stream evolution near pericenter. Our model evolves the longitudinal stream stretching and both transverse widths simultaneously. For the latter, we identify two regimes depending on whether the dynamics is entirely dominated by the tidal force (ballistic regime) or additionally influenced by pressure and self-gravity (hydrostatic regime). We find that the stream undergoes transverse collapses both shortly after the stellar disruption and upon its return near the black hole, at specific locations determined by the regime of evolution considered. The stream evolution predicted by our model can be used to determine the subsequent interactions experienced by this gas that are at the origin of most of the electromagnetic emission from TDEs. Our results suggest that the accretion disk may be fed at a rate that differs from the standard fallback rate, which would provide novel observational signatures dependent on black hole spin.
A New Method for Measuring Infrared Band Strengths in H2O Ices: First Results for OCS, H2S, and SO2
Authors: Yarnall Yukiko Y. , Hudson Reggie L.
Published: May 2022

Infrared (IR) band strengths are needed to extract accurate molecular abundances from astronomical observations of interstellar and solar system ices. However, laboratory measurements of such intensities often have required multiple assumptions about ice composition and thickness. Here we describe a method that circumvents most of the common assumptions and uncertainties in IR band-strength determinations. We have applied the method to measure IR band strengths of OCS, H2S, and SO2 in the absence and presence of H2O ice at 10 K, the first measurements of their type. Our results show for the first time that the presence of H2O makes little difference in IR intensities for these three sulfur-containing molecules’ strongest IR features. The immediate application will be to laboratory studies of low-temperature chemistry of interstellar and cometary ices.
Detecting the Memory Effect from a Massive Black Hole Merger at the Galactic Center through Lunar Ranging
Authors: Loeb Abraham
Published: May 2022

A gravitational wave pulse from a major merger of massive black holes at the Galactic center induces a permanent increase in the Earth–Moon separation. For black holes of mass ∼106 
M
⊙, the shift in the local gravitational potential is comparable to the Earth–Moon potential, leading to the Moon being perturbed relative to the Earth during the passage of the pulse. The permanent increase in the Earth–Moon separation is a fraction of a millimeter, measurable by lunar ranging for future merger events.
A newly discovered southern HgMn star: HD 4065A
Authors: Monier Richard , Niemczura Ewa
Published: May 2022

Evidence is presented that HD 4065A is a newly discovered HgMn star. The Hg ii line at 3983.93 Å is present in two spectra acquired with the High Resolution Spectrograph mounted behind the South African Large Telescope and separated by about 2 months and 25 days. The lines on the second spectrum are redshifted reflecting the orbital motion of HD 4065A around the center of mass of a binary system. The far-ultraviolet spectrum, SWP 20399 collected with IUE, shows a strong resonance line of Ga ii usually conspicuous in the far-ultraviolet spectra of HgMn star. A first spectrum synthesis of the spectral range from 3900 up to 4000 Å yields estimates of the abundances of calcium (0.10 solar), zirconium (25 solar) and mercury (50,000 solar).
