Magma Degassing andGoldMineralizationinthe Alkaline Intrusion- HostedGiltEdgeGoldDeposit,NorthernBlackHills, SouthDakota,USA
Authors: Groff John A. 
Published: October 2024

Gold mineralization in the Gilt Edge deposit was closely associated with magmatic differentiation and the formation of a Tertiary alkaline intrusive complex within the Lead–Deadwood dome.. Fluid inclusions and trace element geochemistry were used to study fluid evolution and determine sources. Quartz disseminated in unaltered trachyte porphyry hosts two populations of primary inclusions: 1) hypersaline i S–L–V a red hematite crystal and 2) mixtures of L–V and V– L that record phase separation at ~700oC. Whereas samples of hydrothermal quartz collected from in ore zones within and beyond structures (e.g., fault and breccia zones) contain dominant populations of V–L and L–V inclusions, respectively. Mineralization in structures formed from complex fluids of magmatic origin based on inclusions containing five transparent salt crystals and opaque crystals with cubic and round habits that have homogenization temperatures (Th) 650oC and salinities 63 wt.% NaCl equiv. In contrast, broader areas of disseminated mineralization in argillized and propylitized rocks contain hydrothermal quartz hosting large populations of L–V inclusions with Th of 200o360oC and salinities of 10–30 wt.% NaCl equiv., which reflect fluid mixing. Trace element concentrations are significantly higher in samples from structures and define zones of near surface Ag–As–Zn–Pb and deep Au–W–Mo–Cu. Whereas low trace element concentrations characterize propylitized quartz trachyte porphyry, except for high concentrations of Sb and Hg that occur at depth and likely track the retreat of isotherms as the hydrothermal system collapsed. These data show that during differentiation in a deep magma chamber, volatile-rich low-density fluids were periodically degassed into preexisting structures that were reactivated. Gold deposition during four stages of mineralization likely occurred due to boiling, changes in oxygen fugacity, and fluid mixing.

Authors: Lekule Thaddeus Aloyce , Mwiturubani Donald Anthony 
Published: October 2024

This paper assessed the level of livelihood strategies practiced by Maasai pastoralists in Longido district, Tanzania. It focused on their resilience to climate variability. The main question that this sought to address was: How resilient are livelihood strategies to climate change and variability among the Maasai pastoralists in response to climate variability? This study employed the resilient theory by Holling and the DFID Livelihood Framework. The study used a mixed-method design, also known as a convergent parallel design. A multistage sampling technique was used to purposefully select wards, then villages, and then a simple random selection of the 373 households for the survey. This study purposively selected 21 key informants from traditional leaders, ward and village leaders, NGO officials, and livestock officers. While data gathered through interviews, observation and focus group discussions was analysed qualitatively. Data obtained through questionnaires was analysed quantitatively using IBM SPSS (version 20). The chi-square was used to test the association of the variables. Findings revealed that key strategies such as mobility, communal pooling, causal labour, livestock management, and others. Also, the role of education and sources of income were crucial in shaping resilience strategies. Household with more education were more likely to have reliable resilience strategies. The main challenge faced by Maasai pastoralists in building climate resilience strategies is increased variability in climate, in the form of frequent drought and unreliable rainfall. This paper recommends more efforts to understand and support these communities by blending their traditional strategies with technical ones for sustainable livelihoods

Accounts receivable management is crucial for companies, especially those selling products on credit. Effective management of receivables ensures that credit returns are handled efficiently, leading to increased company revenue. In this final project, it is noted that receivables management at Perumda BPR Bank Kota Bogor is carried out both manually and through a system. Despite this, problematic and non-performing loans still occur. These problematic and non-performing loans arise due to internal factors within the bank, such as errors in credit analysis and inadequate data verification. Additionally, external factors from the debtors include a decrease in the debtor's payment ability, business losses, reassignment or termination of the debtor, and the misuse of credit by the debtor for purposes other than intended. The resolution of problematic and non-performing loans has been addressed through rescheduling, reconditioning, restructuring, collateral takeovers, and write-offs. Perumda BPR Bank Kota Bogor also undertakes measures to minimize the occurrence of problematic and non-performing loans in the future by conducting detailed and accurate credit analysis, regular monitoring, and maintaining good relationships with debtors.

Keywords: Receivables Management, Causes of Non-Performing Loans, Resolution of Non-Performing Loans

Abstract
We present our optical observations and multiwavelength analysis of the GRB 200613A detected by the Fermi satellite. Time-resolved spectral analysis of the prompt gamma-ray emission was conducted utilizing the Bayesian block method to determine statistically optimal time bins. Based on the Bayesian Information Criterion, the data generally favor the Band+blackbody (BB) model. We speculate that the main Band component comes from the Blandford–Znajek mechanism, while the additional BB component comes from the neutrino annihilation process. The BB component becomes significant for a low-spin, high-accretion-rate black hole central engine, as evidenced by our model comparison with the data. The afterglow light curve exhibits typical power-law decay, and its behavior can be explained by the collision between the ejecta and the constant interstellar medium. Model fitting yields the following parameters:

TESS Asteroseismic Masses and Radii of Red Giants with (and without) Planets
Authors: Pope Myles , Carlberg Joleen K. , Valenti Jeff , Branton Doug 
Published: October 2024

Abstract
We present a study of asteroseismically derived surface gravities, masses, and radii of a sample of red giant stars both with and without confirmed planetary companions using TESS photometric light curves. These red giants were drawn from radial velocity surveys, and their reported properties in the literature rely on more traditional methods using spectroscopy and isochrone fitting. Our asteroseismically derived surface gravities achieved a precision of ∼0.01 dex; however, they were on average ∼0.1 dex smaller than the literature. The systematic larger gravities of the literature could plausibly present as a systematic overestimation of stellar masses, which would in turn lead to overestimated planetary masses of the companions. We find that the fractional discrepancies between our asteroseismically determined parameters and those previously found are typically larger for stellar radii (∼10% discrepancy) than for stellar masses (<5% discrepancy). However, no evidence of a systematic difference between methods was found for either fundamental parameter. Two stars, HD 100065 and HD 18742, showed significant disagreement with the literature in both mass and radii. We explore the impacts of updated stellar properties on inferred planetary properties and caution that red giant radii may be more poorly constrained than uncertainties suggest.
XMM-Newton Perspective of the Unique Magnetic Binary-ϵ Lupi

Published: October 2024

Abstract
The ϵ Lupi A (HD 136504) system stands out among magnetic massive binaries as the only short-period binary system in which both components have detectable magnetic fields. The proximity of the magnetospheres of the components leads to magnetospheric interactions, which are revealed as periodic pulses in the radio light curve of this system. In this work, we aim to investigate the magnetospheric interaction phenomenon in the X-ray domain. We observed this system with the XMM-Newton telescope, covering its orbital period. We observe variable X-ray emission with maximum flux near periastron, showing similarity with radio observations. The X-ray spectra show significantly elevated hard X-ray flux during periastron. We attribute the soft X-ray emission to individual magnetospheres, while the hard X-ray emission is explained by magnetospheric interaction, particularly due to magnetic reconnection. However, unlike in the radio, we do not find any significant short-term X-ray bursts. This exotic system may be an ideal target to study magnetospheric interactions in close binaries with organized magnetospheres.
Nonthermal Signatures of Radiative Supernova Remnants
Authors: Diesing Rebecca , Guo 郭 Minghao 明浩 , Kim Chang-Goo , Stone James , Caprioli Damiano 
Published: October 2024

Abstract
The end of supernova remnant (SNR) evolution is characterized by a so-called “radiative” stage, in which efficient cooling of the hot bubble inside the forward shock slows expansion, leading to eventual shock breakup. Understanding SNR evolution at this stage is vital for predicting feedback in galaxies, since SNRs are expected to deposit their energy and momentum into the interstellar medium at the ends of their lives. A key prediction of SNR evolutionary models is the formation at the onset of the radiative stage of a cold, dense shell behind the forward shock. However, searches for these shells via their neutral hydrogen emission have had limited success. We instead introduce an independent observational signal of shell formation arising from the interaction between nonthermal particles accelerated by the SNR forward shock (cosmic rays) and the dense shell. Using a semi-analytic model of particle acceleration based on state-of-the-art simulations coupled with a high-resolution hydrodynamic model of SNR evolution, we predict the nonthermal emission that arises from this interaction. We demonstrate that the onset of the radiative stage leads to nonthermal signatures from radio to gamma rays, including radio and gamma-ray brightening by nearly 2 orders of magnitude. Such a signature may be detectable with current instruments, and will be resolvable with the next generation of gamma-ray telescopes (namely, the Cherenkov Telescope Array).

Background: The rapid revolutionisation of technology and other factors such as the recent COVID-19 pandemic, prompted higher education institutions to consider the possibility, necessity and implications of officially adopting a blended teaching and learning approach on a long-term basis.Aim: This research aimed to explore the practicality of a long-term blended teaching and learning model at a South African higher education institution.Setting: This research was conducted at a selected South African higher education institution.Methods: The article adopted a qualitative case study approach, and one-on-one semi-structured interviews were conducted. The data collected was then analysed using thematic analysis.Results: Although the institution was generally ready for blended teaching and learning during the pandemic, best practices such as further training and development for both lecturers and students on the pertinent systems and technology are imperative if a long-term blended teaching and learning is to be successful. There were also concerns regarding external, technological, and socio-economic issues that could hinder a successful long-term blended model.Conclusion: While the research revealed the institution’s overall ability to swiftly transition from face-to-face, to distance online and blended teaching and learning approaches during the COVID-19 pandemic, it also revealed that work still had to be done to fully prepare the institution for formalised blended teaching and learning in the future.Contribution: This research builds on limited research on blended teaching and learning at South African contact higher education institutions and adds new theory regarding some best practices for successful blended teaching and learning.
