The Origin of the Consistent Planetary Nebula Luminosity Function Bright-end Cutoff
Authors: Yao Philippe Z. , Quataert Eliot 
Published: October 2023

Abstract
The [O iii] 5007 Å line is typically the brightest line in planetary nebula (PN) spectra. Observations show that the brightest [O iii] 5007 Å PN in a galaxy—the planetary nebula luminosity function (PNLF) bright-end cutoff—is surprisingly independent of galaxy type. To understand the origin of this puzzling uniformity, we simulate PNe with a range of cloud and star parameters using the photoionization code CLOUDY. We find that the peak [O iii] 5007 Å luminosity depends weakly on both the central stellar effective temperature at high temperature and on the total PN ejecta mass; however, the peak [O iii] 5007 Å luminosity depends strongly on the central stellar luminosity and the PN dust-to-gas mass ratio. We explain these scalings physically. They imply that a higher dust-to-gas mass ratio at higher central stellar luminosity can help explain a constant bright-end cutoff in the PNLF across galaxy types. This prediction is testable with a survey of galactic PNe. The surviving remnants of double white dwarf (WD) mergers should also produce photoionized nebulae analogous to PNe. These may be preferentially present at the high luminosity end of the [O iii] PLNF and could explain the existence of PNe in early-type galaxies that are more luminous in [O iii] than expected from single-star evolutionary models. The presence of WD mergers in both young and old stellar populations could contribute to the uniformity of the [O iii] PNLF across galaxy types; such nebulae would lack the hydrogen lines otherwise characteristic of PNe.

Abstract
High-resolution solar spectroscopy provides a wealth of information from photospheric and chromospheric spectral lines. However, the volume of data easily exceeds hundreds of millions of spectra on a single observation day. Therefore, methods are needed to identify spectral signatures of interest in multidimensional data sets. Background-subtracted activity maps (BaSAMs) have previously been used to locate features of solar activity in time series of images and filtergrams. This research note shows how this method can be extended and adapted to spectral data.
Les ressources naturelles russes à l’heure de la guerre en Ukraine : un atout empoisonné ?
Authors: Radvanyi Jean 
Published: October 2023

Avec son cortège de destructions, de sanctions et de boycotts, la guerre russe en Ukraine bouleverse les flux mondiaux de matières premières. En lançant en 2022 une guerre totale contre son voisin, V. Poutine comptait sur la dépendance énergétique européenne pour limiter le soutien occidental envers Kiev. La guerre se prolongeant, c’est l’économie russe, très dépendante de ses exportations vers l’UE qui se trouve affaiblie. Des auteurs occidentaux prévoient déjà l’effondrement d’une économie, incapable de remplacer les ventes de gaz transitant par un réseau de gazoducs désormais fermés, voire détruits. Pourtant, plusieurs signes font douter d’un scénario aussi pessimiste. Si le volume d’exportation et donc le budget russe est réduit, Moscou développe depuis des années une stratégie de substitution, tant sur le plan technique (essor du LNG) que par une diversification de ses clients. Sur ce plan, le Kremlin compte sur ses nombreux alliés et clients du « Sud global ».
La « désoccidentalisation » comme stratégie russe de transformation de l’ordre international
Authors: Daniélou Maxime 
Published: October 2023

Cet article propose une analyse de la « désoccidentalisation » comme stratégie englobant un ensemble de mesures mises en place par la Russie pour réduire l’influence des États-Unis, de l’Union européenne et de leurs alliés sur la scène internationale. À court terme, cette stratégie a pour but de réduire les effets des sanctions économiques, contrer la tentative d’isolement diplomatique de la Russie et endiguer le support militaire et économique à l’Ukraine. Dans un temps plus long, elle a pour objectif d’accroître l’influence de la Russie dans un ordre international « post-occidental » ou le groupe des BRICS est appelé à jouer un rôle déterminant.
L’area monumentale di Tusculum: nuove ricerche e proposte interpretative (età arcaica - età imperiale)
Authors: Bianco Rosy , Pizzo Antonio 
Published: October 2023

[it] Questo contributo presenta una sintesi delle nuove ricerche effettuate a Tusculum tra il 2018 e il 2023. Gli scavi si svilupparono nell’area monumentale della città e nella zona meridionale del foro. Presentiamo una sistematizzazione della documentazione archeologica prodotta in quasi 30 anni di ricerche della EEHAR e nuove proposte interpretative su edifici parzialmente scavati nel corso delle prime campagne e adesso integralmente portati alla luce (basiliche). Per la prima volta nella storia degli studi sul foro tuscolano sono state realizzate una serie di piante con la periodizzazione dell’area. Esse favoriscono un racconto coerente dell’evoluzione diacronica della zona in esame. Attraverso l’integrazione dei nuovi dati di scavo, presentiamo una pianta archeologica del foro con le differenti fasi e una sintesi grafica che rende chiari i vari passaggi storici nell’area monumentale. I dati dei nuovi scavi aprono ulteriori riflessioni sulla tipologia degli edifici forensi di Tusculum. In primo luogo sulle cronologie delle due basiliche presenti nel foro in due diversi periodi della storia urbana e, successivamente, sull’interpretazione di un edificio parzialmente conosciuto e completato nelle campagne citate (Curia / Tempio). In una seconda parte dell’articolo, gli interventi edilizi si relazionano alla storia della città conosciuta dalle fonti storiche ed epigrafiche.

Abstract
The Red Lakes, Minnesota supported a substantial Walleye Sander vitreus fishery from the early to mid-20th century but experienced a major crash in the late 1990s. The population has since rebounded after a successful interagency recovery program and now supports valuable commercial and recreational fisheries. The variation in population densities associated with the collapse and subsequent recovery in the Red Lakes Walleye population provides a rare opportunity to study potential changes in relative fecundity (eggs/kg of body mass) under varying rates of exploitation: overexploited (1989 data), recovering (2004 data), and recovered (2017 data). We collected female Walleye in spring of 1989 (n = 30) from the Blackduck and Tamarac rivers and in spring of 2004 (n = 30) and 2017 (n = 30) from the Tamarac River. Results indicate that relative fecundity was significantly lower in 2017 (50,768, SD = 10,266) than in 1989 (58,216, SD = 6,211) and 2004 (61,964, SD = 7,472). We hypothesize that differences in relative fecundity among fishery states were due to differences in Walleye population abundances caused by varying exploitation rates in the years leading up to fecundity estimates.
Les zones de production du fer en Bourgogne-Franche-Comté : une approche sur la longue durée par le radiocarbone
Authors: Berranger Marion , Leroy Marc , Laurent Hervé 
Published: October 2023

Dès les années 1980, des campagnes de prospections archéologiques ont été conduites dans le nord-est et le centre-est de la France afin d’inventorier les sites sidérurgiques anciens, ce qui a conduit à en recenser plus d’un millier très inégalement répartis. Les données chronologiques restaient cependant trop ponctuelles pour tenter d’esquisser l’évolution des activités de réduction du minerai de fer dans cet espace géographique. Sur la base de ces inventaires, un programme collectif de recherche a débuté dans le courant des années 2010, afin de préciser la chronologie des zones de réduction en Bourgogne-Franche-Comté. Son objectif a été de dater un grand nombre de ces ateliers en tentant de recourir le plus systématiquement possible à la réalisation de datations par le radiocarbone sur des charbons prélevés en stratigraphie ou au sein de scories métallurgiques. Plus de 159 nouvelles dates ont ainsi été acquises, permettant de disposer, en tenant compte de celles déjà disponibles, de 210 dates exploitables issues de 159 sites. L’objet de cet article est de présenter les résultats de ces nouveaux travaux qui modifient substantiellement notre perception de la chronologie de la production du fer dans cette région.

Published: October 2023

In this latest addition to the Two Horizons New Testament Commentary series, biblical scholar Jeannine Brown and theologian Kyle Roberts together illuminate the Gospel of Matthew for pastors, scholars, and serious students of Scripture.
Including an original translation of the text along with section-by-section commentary, this volume features chapters on “thinking theologically with Matthew” about such themes as kingdom, Christology, the Holy Spirit, and discipleship. Brown and Roberts also offer constructive theological engagement with a number of contemporary viewpoints, including feminist, global, political, and ethical (post-Holocaust) perspectives. At once interdisciplinary and insightful, their commentary will appeal to a wide readership.
A rapid semi-quantitative screening method to assess chemicals present in heated e-liquids and e-cigarette aerosols

Published: October 2023

Abstract. ​​​​​​​Electronic cigarettes (e-cigarettes) lack regulatory status as therapeutic products in all jurisdictions worldwide. They are potentially unsafe consumer products, with significant evidence they pose a risk to human health. Therefore, developing rapid, economical test methods to assess the chemical composition of e-liquids in heated and unheated forms and the aerosols produced by e-cigarettes is crucial. Four different e-liquids were heated using two different methods: (1) “typical” vaping using an e-cigarette device, by cycling “on” for 3 s every minute for 2 h (e-liquid obtained from remainder in the tank and aerosol collected in an impinger), and (2) “accelerated” heating, using an e-cigarette coil submerged in e-liquid and heating in short 20 s bursts on then 20 s off for 2 min only (liquid traps aerosol produced). All e-liquids were then analysed to test for the presence and quantity of 13 chemicals by gas chromatography–mass spectrometry and compared to an unheated sample. E-liquids heated with the accelerated method showed a comparable trend to the typical heating method, i.e. increase or decrease in chemical compound quantity, for more than two-thirds of the detected compounds analysed over all e-liquids. Six chemicals were detected as aerosol from the impinger fluid with the typical heating method at negligible levels. We propose that this accelerated version of the typical vaping method could form the basis of a standardized screening tool to test heated e-liquids (and e-cigarette aerosols) for harmful or banned substances. This will ensure that only approved products reach the consumer and reduce potential e-cigarette harm.

Abstract. The Mediterranean Forecasting System produces operational analyses and reanalyses and 10 d forecasts for many essential ocean variables (EOVs), from currents, temperature, salinity, and sea level to wind waves and pelagic biogeochemistry. The products are available at a horizontal resolution of 1/24∘ (approximately 4 km) and with 141 unevenly spaced vertical levels. The core of the Mediterranean Forecasting System is constituted by the physical (PHY), the biogeochemical (BIO), and the wave (WAV) components, consisting of both numerical models and data assimilation modules. The three components together constitute the so-called Mediterranean Monitoring and Forecasting Center (Med-MFC) of the Copernicus Marine Service. Daily 10 d forecasts and analyses are produced by the PHY, BIO, and WAV operational systems, while reanalyses are produced every ∼ 3 years for the past 30 years and are extended (yearly). The modelling systems, their coupling strategy, and their evolutions are illustrated in detail. For the first time, the quality of the products is documented in terms of skill metrics evaluated over a common 3-year period (2018–2020), giving the first complete assessment of uncertainties for all the Mediterranean environmental variable analyses.
Modelling the historical and future evolution of six ice masses in the Tien Shan, Central Asia, using a 3D ice-flow model
Authors: Van Tricht Lander , Huybrechts Philippe 
Published: October 2023

Abstract. In the Tien Shan, few modelling studies exist that examine in detail how individual ice bodies are responding to climate change. Nonetheless, earlier research demonstrated that the glacier response to climate change in this mountain range is heterogeneous. Here, we use several measurements and reconstructions of the ice thickness, surface elevation, surface mass balance, and ice temperature to model in depth six different ice bodies in the Kyrgyz Tien Shan: five valley glaciers and one ice cap. The selected ice masses are located in different sub-regions of the Tien Shan with different climatic and topographic settings, and they are all characterized by detailed recent glaciological measurements. A three-dimensional higher-order thermomechanical ice-flow model is calibrated and applied to simulate the evolution of the ice masses since the end of the Little Ice Age (1850) and to make a prognosis of the future evolution up to 2100 under different Coupled Model Intercomparison Project Phase 6 (CMIP6) shared socioeconomic pathway (SSP) climate scenarios. The results reveal a strong retreat of most of the ice masses under all climate scenarios, albeit with notable variations in both timing and magnitude. These can be related to the specific climate regime of each of the ice bodies and their geometry. Under a moderate warming scenario, the ice masses characterized by a limited elevation range undergo complete disappearance, whereas the glaciers with a larger elevation range manage to preserve some ice at the highest altitudes. Additionally, our findings indicate that glaciers that primarily receive precipitation during the late spring and summer months exhibit a more rapid retreat in response to climate change, while the glaciers experiencing higher precipitation levels or more winter precipitation remain for a longer duration. Projections concerning the overall glacier runoff reveal that the maximum water discharge from the ice masses is expected to occur around or prior to the middle of the 21st century and that the magnitude of this peak is contingent upon the climate scenario, with a higher warming scenario resulting in a higher peak.
Artificial Earth
Authors: Andersson J. Daniel 
Published: October 2023

Artificial Earth: A Genealogy of Planetary Technicity offers an intellectual history of humanity as a geological force, focusing on a prevalent contradiction in the Anthropocene discourse on global environmental change: on the one hand, it has been argued that there are hardly any pristine environments anymore, to the degree that the concept of nature has lost its meaning; while on the other, that anthropogenic environmental change has become so prevailing that it ought to be conceived of as a force of nature, in the literal sense of the expression. Artificial Earth argues that to fully grasp the stakes of this discourse, we need not only understand the contemporary scientific and technological transformations behind the Anthropocene, but also explore the history of an ontological concern tied up with it.
In order to do so, Artificial Earth examines reflections on the ontological dualism between nature and artifice within the history of earth science from the late eighteenth century onwards. Paying particular attention to its consequences for how human subjectivity has been conceptualized in the Anthropocene, it then enrolls these resources in an effort to problematize attempts since the 1980s to formalize earth science in systems theory terminology. In sum, the aim is to investigate the historical conditions for the possibility of conceiving human artifice as an integral part of the earth’s terrestrial environment, with the conviction that such an investigation may assist in resolving the aforementioned contradiction or at least to understand it better by tracing its historical lineage.
Knowledge and Attitude of Medical Students about Insulin Resistance Symptoms, Effect, and Treatment
Authors: Shihab Alaa Saber 
Published: October 2023

The inability of the target organs to react appropriately to the action of insulin is known as insulin resistance. Insulin resistance impairs insulin-mediated glucose absorption in the peripheral (skeletal muscle and adipose tissue), which results in increased blood sugar levels and increase insulin demand. Aim: This study aims to assess medical students' knowledge and attitudes on the signs, consequences, and treatments of insulin resistance. Patients and methods: There were 160 medical students at Tikrit University in all, male and female. The average age of students in the primary stages was 20 years, while that of students in the clinical stages was 23 years old. The current study, which was conducted in 2023 at Tikrit University College of Medicine (TUCOM), is cross-sectional in nature. All data presented statically as percentage. Results: There are three forms of diabetes mellitus, according to 43.75 percent of medical students. One of the complications of DM, according to (90.63 %) of them, is vision problems. Diet modification and exercise were preferable than oral hypoglycemic drugs and insulin therapy. Conclusions: The study found that (75%) of medical students recognized the link between type 2 DM and insulin resistance, with clinical students showed a higher level of awareness in comparison with preclinical students.
O trabalho educativo na socioeducação e o fortalecimento do laço civilizatório

Published: October 2023

Este estudo relata uma pesquisa realizada junto aos professores de uma escola inserida em uma unidade de internação, sob a tutela da justiça para adolescentes em conflito com a lei. Utilizou-se a metodologia de pesquisa qualitativa proposta em Psicodinâmica do Trabalho. Coloca-se em discussão o sentido do trabalho em uma instituição com um caráter ao mesmo tempo carcerário e socioeducativo. A escuta no espaço coletivo de fala para esses professores revelou a parte sombria deste trabalho, mas, ao mesmo tempo, uma dimensão de reinvenção com o enlace dos vínculos com a cultura. O lado sombrio se relacionou às narrativas de violência, precariedade social e desesperança dos adolescentes, bem como, pelo descaso das políticas públicas para este segmento da população. Por outro lado, a reinvenção nesse trabalho se revelou na tentativa de inscrição desses adolescentes em laços civilizatórios, por meio do investimento em elementos da cultura. Esse espaço coletivo apontou que o sentido desse trabalho na socioeducação é sustentado por ambições educativas e inclusivas, que convoca a uma ética de atenção ao outro revestida de valor civilizatório, por sua vez, tão destruída na experiência de enclausuramento.
Electrocatalytic response of nitrogen-doped hollow carbon spheres modified glassy carbon electrode for sulphite detection in water
Authors: Basande Ashkan , Beitollahi Hadi 
Published: October 2023

In this work, the glassy carbon electrode (GCE) surface was modified with nitrogen-doped hollow carbon spheres (N-HCSs) to achieve a new electrochemical sulphite sensor (N-HCSs/GCE) in water samples. The N-HCSs were explored for electrocatalytic behavior through voltammetric approaches using a routine three-electrode system. The findings revealed an admirable efficiency for modified electrodes towards sulphite oxidation, highlighting the effectiveness of our as-produced sulphite sensor. The differential pulse voltammetry was utilized under obtained optimal circumstances to study the as-developed sensor, the results of which underlined linear electrochemical current in relation to sulphite concentration, with dynamic range as wide as 1.0-100.0 μM and limit of detection as narrow as 0.35 μM. Moreover, N-HCSs/GCE had commendable practical applicability for sensing sulphite present in real specimens with voltammetric techniques.

Published: October 2023

Objective: It was aimed to investigate the antibacterial effect levels of Lactoferrin protein in cow colostrum. The aim of the study was to evaluate the effect of lactoferrin protein obtained from a natural product on the growth of Escherichia coli, Pseudomonas aerugenosa and Staphylococcus aureus.
Method: Lactoferrin at 4 different concentrations (100 mg/ml, 50 mg/ml, 25mg/ml and 12.5mg/ml) was impregnated on 6 mm discs prepared from filter paper and placed on the MHA plate and after incubation at 37˚C for 24 hours, inhibition was evaluated. The antibacterial effect levels of naturally obtained lactoferrin at different concentrations were compared.
Results: It was determined that the antibacterial activity of lactoferrin against Gram-negative bacteria Pseudomonas aeruginosa was higher than the other bacterial species in the study. It was determined that Lactoferrin at a concentration of 12.5mg/ml had the least inhibitory effect in the studied bacteria. It was concluded that E.coli and S. aureus were bacteria resistant to the antibacterial activity of lactoferrin.
Conclusion: It was observed that this effect was limited in E.coli bacteria. In the light of these results, it was concluded that Lactoferrin, an antibacterial agent, has different antibacterial effects depending on the bacterial species and dose.
