The modern surface of Mars does not sustain liquid water, however relict landforms observed on orbital images provide strong evidence of past aqueous activity. Nevertheless on-the-ground analysis of sedimentary strata are required to robustly characterise the specific nature of early Mars palaeoenvironments. The Mars 2020 Perseverance rover is exploring a prominent sedimentary fan deposit at the western margin of Jezero crater – the Western fan – which has been interpreted to be an river delta that prograded into an ancient lake basin during the Late Noachian-Early Hesperian epochs on Mars (~3.6-3.8 Ga). Perseverance’s traverse across the fan in 2022-2023 provides a remarkable window into a fossilised sediment routing system on Mars with potential to understand how water and sediment were distributed across a Martian landscape under a markedly different climate to present day. Here we use the rover’s cameras to characterise sedimentary geometries in a distal to proximal transect across the western fan and reconstruct sediment dynamics on the Western fan and infer past environmental change. The distal reaches of the preserved fan show a sedimentary succession that records a transition from distal alluvial fan into lacustrine and subsequently foreset delta deposits. This succession records the initiation of a martian lake system and lake level rise, though overlying delta stratal geometries suggest deposition during episodes of lake level fall. In the medial sector of the upper exhumed portion of the fan, complex stratal geometries are observed with a variety of scenarios for palaeoenvironmental interactions possible. In particular, the presence of large-scale foreset units preserved in this ‘mid-fan’ sector possibly suggests complex deltaic interfingering with fluvial strata during lake level fluctuations. In more proximal and stratigraphically higher (and hence younger) sectors of the fan, we observe strata deposited by progradation of fluvial systems culminating in a sequence of rounded boulder-containing deposits that signal transition to a routing system characterised by high discharges. Misquoting Shakira “the sediments don’t lie”; they record a history of sustained water transport and habitability on early Mars.
How old are Saturn’s rings?

Published: July 2024

One of the most exciting and controversial aspects of Saturn’s magnificent rings is that they may actually be a recent phenomenon in the solar system – forming long after the Earth, Saturn, and its moon. This possibility has been vigorously debated for nearly 40 years, since the Voyager flybys of Saturn. Over the years, the most powerful support for this hypothesis has turned out to be the puzzle of the rings’ nearly pure water ice composition – unique in the family of planetary rings – in spite of the constant hail of rocky-carbon meteoroids from outside the Saturn system. However, three major uncertainties have left the young-ring hypothesis unproven. Two of these have already been resolved by the Cassini mission: the amount of non-icy material currently in the rings, and the total ring mass. The third main constraint is the mass flux of non-icy meteoroids falling onto the rings. Measuring this mass flux was always a main science goal of the Cassini mission, and could only be achieved by the Cassini Cosmic Dust Analyzer instrument (CDA). In this talk we will report about the determination of the mass flux of non-icy material coming into the Saturn system, which completes the trifecta of constraints that are required to strongly support a youthful ring system [1]. The measurements present a thorough and detailed analysis of the series of unconnected individual particle detections by CDA over Cassini’s entire 13 year mission, converting these detections into the desired mass flux. The CDA detections determine the incident particle orbits, and they come (surprisingly) not from comets as expected, but mostly from Kuiper Belt Objects. This means that most of the particles have low speeds relative to Saturn and are strongly focused gravitationally, such that the flux at the rings is even larger than previously estimated. The derived mass flux implies a ring exposure time of less than 100 to 400 million years, which is in support of recent ring formation scenarios.
Advancing Exoplanet Research with MARCOT: Innovative Photonic Lantern Integration for Enhanced Spectroscopic Capabilities

Published: July 2024

The MARCOT-Pathfinder Telescope (MPT), situated at the Calar Alto Observatory (CAHA) in Spain, represents the integration of a state-of-the-art Multi-Mode Photonic Lantern for usage with high-resolution spectrographs, enhancing the MARCOT-Pathfinder's optical efficiency and observational capabilities. Unlike conventional systems, the MARCOT-Pathfinder employs an array of seven small Optical Tube Assemblies (OTAs), each equipped with advanced fibre positioning systems to channel stellar light into the Multi-Mode Photonic Lantern. We will present the status of the project and summary of the studies that remain to be carried out, focusing on the work carried out to connect the MPT to a a readily available low-resolution spectrograph. The MPT is a demonstrator of what could represent a significant leap in astronomical instrumentation for exoplanets research. It is the first phase of the MARCOT project which aim at developing a large aperture ground-based telescope combining several modules of tens of OTAs and reducing the cost compared to a traditional design of a telescope of the same size. For this purpose, off-the-self telescopes and commercial instrumentation have been used. A feature of this telescope is that it is modular, which allows us to increase the effective aperture by adding individual modules. The project is divided into different phases, the first of which is to demonstrate the functionality of this technology with the MPT. In phase-two we want to build a telescope with a 5-m effective aperture, using individual modules. Finally, the last phase will be to use several modules of 5-m effective aperture giving a total effective aperture of 15-m. MARCOT will be installed at Calar Alto Observatory with each of its modules enclosed in its own small dome. This innovative setup allows for a unique, combination of the light collected by each individual telescope, effectively emulating a larger, monolithic telescope’s light-gathering power but at a fraction of the cost and complexity. The integration significantly increases the signal-to-noise ratio, crucial for detecting exoplanets around faint stars. The driver science case will be the detection and characterization of exoplanets, to which we will dedicate most of the guaranteed time observations. Specifically, with a MARCOT telescope featuring a 5-m effective aperture, we could access over 400 exoplanets already detected by TESS and Kepler, and conduct studies of their masses and densities. Similarly, we are interested in planetary systems around ultracool dwarfs, about which little is currently known. Detecting these faint objects requires large-aperture telescopes to collect more photons and a high-resolution spectrograph to achieve precise measurements of their radial velocity variations.

Published: July 2024

The Australian Universities Accord’s (Department of Education, 2024) focus on expanding underrepresented groups’ access to higher education underscores an on-campus-online paradigm shift, or post-pandemic digital transformation, to address students’ flexibility and accessibility needs. The shift identifies that online student engagement, and students’ learning outcomes, need to be effective and fit for purpose if students are to succeed. Conducted as one phase of a longitudinal project (2017-present), this research investigated the approaches and strategies that could be incorporated to facilitate students’ online engagement. Findings suggest that these strategies could be encapsulated under five key conditions: fashioning a strong teacher presence; crafting an inclusive and safe online learning environment; creating well-structured and interesting content; forging explicit expectation management; and ensuring students have time to engage. This article argues that if educators are purposeful in applying these conditions, employing targeted, specific strategies in their curriculum design and teaching, students’ online engagement, and their learning outcomes, will be enhanced.
De excavar con las manos a la impugnación política. Análisis comparativo de exhumaciones durante el franquismo, la transición y la democracia
Authors: Pérez Guirao Francisco Javier
Published: July 2024

Las exhumaciones de fosas comunes no es un fenómeno reciente en nuestro país. Mientras el franquismo logró recuperar a sus mártires y caídos por Dios y por España desde justo después de acabada la contienda bélica, homenajeándolos con todo tipo de honores y distinciones, a las familias de los republicanos asesinados no se les concedió el beneplácito de recuperar sus cadáveres. Sus cuerpos dañados, despreciados y abandonados, sin sus exequias y con duelo público prohibido, permanecieron en fosas comunes anónimas. Este artículo, a partir de una etnografía de las exhumaciones del golpe militar de 1936 en la provincia de Cádiz, realiza un análisis comparativo de las mismas durante la dictadura, la transición y la democracia, mostrando sus aspectos comunes, particularidades y diferencias para apreciar la evolución y la influencia de los contextos políticos y sociales en estos procesos. Se han seleccionado dos casos considerados significativos e ilustrativos durante cada uno de estos tres ciclos para una mejor comprensión del significado de las demandas reivindicativas por la recuperación de la memoria, una lucha que tiene su origen durante la propia dictadura y que permanece en la actualidad inacabada.

Сближение систем и стандартов профессионального образования государств-членов ЕАЭС в контексте развития ранка труда ЕАЭС становится все более актуальным по мере углубления интеграционных процессов. Создание научно-образовательных консорциумов по приоритетным областям профессиональной подготовки кадров может стать одним из действенных механизмов реализации V-ой свободы в Евразийском экономическом союзе. Такие консорциумы могут заложить фундамент для дальнейшего углубления сотрудничества стран ЕАЭС в сфере профессионального образования, что особенно актуально в условиях углубления евразийских интеграционных процессов.

Целью исследования являлось изучить весовой рост бычков-кастратов разного генотипа. Объектом исследования являлись чистопородные бычки казахской белоголовой и помеси с герефордами разной доли кровности.  Установлено, что поглотительное скрещивание казахского белоголового скота с герефордами положительно сказывается на повышении весовых показателей. Достаточно отметить, что в годовалом возрасте бычки-кастраты II и III опытных групп превосходили чистопородный молодняк казахской белоголовой пор I (контрольной) группы по живой массе соответственно на 21,1 кг (6,6 %, Р<0,05) и 29,0 кг (9,1 %, Р<0,05).
Установлено преимущество помесей II и III опытных групп по среднесуточному приросту живой массы над чистопородными сверстниками казахской белоголовой породы I (контрольной) группы, которое за весь период выращивания от рождения до 18 мес составляло 50 г(6,1,Р<0,01) и 75 г (9,2%, Р<0,01).
Отмечалось лидирующее положение помесных бычков-кастратов второго поколения ¾ герефорд х ¼ казахская белоголовая) III опытной группы по интенсивности роста во все возрастные периоды.
Virtual Reality Technology in Rural Sports Sustainable Development Reform Research
Authors: Wang Luo
Published: July 2024

Rural sports support unity among communities, encourage physical exercise in natural environments, and preserve regional traditions all of which are beneficial to sustainable development. Villages frequently encourage environmental stewardship and conservation initiatives, highlight cultural history, and promote local economies. By providing realistic practice environments and simulated games, we used virtual reality (VR) technology to improve rural sports and lessen the demand for substantial development infrastructure. A potential disadvantage of adopting VR technology for rural sports is the possibility of insufficient facilities and supplies available in remote areas. In this paper, we propose a novel World Cup Search-driven Quadratic Support Vector Machine (WCS-QSVM) method to enhance the performance of VR in rural sports. We use one of the Chisnese traditional games dragons boating. We employ an immersive setup that replicates the kinematic and sensory subtleties of dragon boating through the use of virtual reality. To allow users to participate in real-world paddling activities, such as moving iron rods on a boat with a reasonably replicated resistance to water, we use a controller-based approach. As a result, we evaluate the performance of our proposal. According to the findings, the use of VR can enhance the growth of sustainable development in rural sports.

The article considers the issues of inclusion in the Agenda of sustainable development of a set of segments/industries that make up the social sector. These segments include education, healthcare, social protection and the housing and communal sector of the economy. The binding of the named segments to the Goals of sustainable development has been established. Groups of national statistical indicators describing the designated segments of the social sector are highlighted. Using the example of the regions that are part of the Northwestern Federal District, an analysis of progress towards achieving the SDGs (namely, the Goals 1, 3, 4 ,8, 10, 11). It was revealed that the greatest degree of progress was demonstrated by the set of subjects that make up the NWFD in relation to the Goals: 1 «Poverty eradication»; 4 «Quality education»; 8 «Decent work and economic growth»; 10 «Reducing inequality» and 11 «Sustainable cities and towns». The least advanced subjects of the NWFD turned out to be in relation to SDG 3 «Good health and well-being».
From market concentration to political corruption [Book review]
Authors: Glenna Leland
Published: July 2024

First paragraph: The government and the press in the United States tend to define corruption narrowly as the misbehavior of individual politicians. They turn a blind eye to systematic corruption such as, for example, the wealthiest people and corporations using campaign contributions to buy political influence. A politician who takes a cash bribe in exchange for a political favor might be deemed corrupt. In contrast, a politician who derails a piece of legislation after receiving a large campaign con­tribution is operating within the limits of the U.S. campaign laws and is, therefore, not deemed corrupt. . . .

Introduction: Medicinal Plant with antimicrobial properties are of great significance in therapeutic treatments of disease caused by bacteria. Their antibacterial properties are due to compounds synthesized in their cell sap during secondary metabolism, their antibacterial activity has shown that plants represent a potential source of novel antibiotic prototypes. This study aims to investigate the antibacterial potential of three plant extracts on S. aureus and E. coli. Method: A comparative study of the antibacterial potentials of water and ethanolic leaf extracts of three plants, Parkia biglobosa, Khaya senegalensis and Daniellia oliveri, was carried out. Extracts at various regimes of concentrations, 0.2 g/ml, 0.4 g/ml, 0.6 g/ml, 0.8 g/ml and 1.0 g/ml were tested against Staphylococcus aureus and Escherichia coli. The disc diffusion method of Kirby Bauer with slight modification was adapted in determining zones of inhibition. Statistical significance was considered at (p<0.05). Results: Ethanolic leaf extract of P. biglobosa recorded the highest zone of inhibition (20.0 mm) at 1.0 g/ml on S. aureus, while ethanolic leaf extract of D. oliveri had the least zone of inhibition (6.33 mm) at 0.2 g/ml on E. coli. K. senegalensis was most effective on E. coli with grand mean inhibitory effect of (13.33 mm and 12.13 mm) on ethanol and water extract respectively, while P. biglobosa was most effective on S. aureus with grand mean inhibitory effect of (13.00 mm and 12.47 mm) on ethanol and water extracts respectively. No significant difference in the grand mean inhibitory effect of the three plants on test bacterial or the type of solvent used. Conclusion: The three plants are potential useful antibacterial agents, inhibiting bacterial growth at all concentrations of the study.
