An Nzema Mother-Tongue Commentary on the Matthean Beatitudes
Authors: Korankye Justice , Boaheng Isaac
Published: February 2024

One of the major challenges facing contemporary Ghanaian Christianity is ineffective discipleship. Consequently, Christianity has little influence on the moral life of its adherents. No wonder Ghana has a high Christian population, yet corruption and wickedness abound in its societies. The priorities of many contemporary Christians have shifted from the pursuit of the kingdom of God and its righteousness to the accumulation of material wealth, the pursuit of upward social mobility and the fixation on earthly gratification, among others. To avert the situation, there is the need for the church to teach biblical principles that will raise disciples of resilient faith for this and generations to come. By drawing out some principles from the Matthean Beatitudes (Matt 5:3-12) as a paradigm for contemporary Christian discipleship, the article sought to contribute to the church’s efforts in dealing with discipleship challenges of current times and beyond. The main argument of this study was that the Christian disciple is called to be different from worldly people in both ethical behaviour and piety. This call to be set apart involves a call to recognise the reality of God’s kingdom; a call to be alongside the poor and sinners; and a call to participate in God’s kingdom community.

Betelgeuse as a Merger of a Massive Star with a
Companion
Authors: Shiber Sagiv , Chatzopoulos Emmanouil , Munson Bradley , Frank Juhan
Published: February 2024

We investigate the merger between a 16M
⊙ star, on its way to becoming a red supergiant (RSG), and a 4M
⊙ main-sequence companion. Our study employs three-dimensional
hydrodynamic simulations using the state-of-the-art adaptive mesh refinement
code Octo-Tiger. The initially corotating binary undergoes
interaction and mass transfer, resulting in the accumulation of mass around the
companion and its subsequent loss through the second Lagrangian point (L2). The
companion eventually plunges into the envelope of the primary, leading to its
spin-up and subsequent merger with the helium core. We examine the internal
structural properties of the post-merger star, as well as the merger environment
and the outflow driven by the merger. Our findings reveal the ejection of
approximately ∼0.6 M
⊙ of material in an asymmetric and somewhat bipolar outflow. We
import the post-merger stellar structure into the MESA stellar evolution code to
model its long-term nuclear evolution. In certain cases, the post-merger star
exhibits persistent rapid equatorial surface rotation as it evolves in the
H–R diagram
toward the observed location of Betelgeuse. These cases demonstrate surface
rotation velocities of a similar magnitude to those observed in Betelgeuse,
along with a chemical composition resembling that of Betelgeuse. In other cases,
efficient rotationally induced mixing leads to slower surface rotation. This
pioneering study aims to model stellar mergers across critical timescales,
encompassing dynamical, thermal, and nuclear evolutionary stages.

Published: February 2024

We present high-spectral-resolution M-band spectra from iSHELL on NASA’s Infrared Telescope Facility along the line of sight to the debris disk host star HD 32297. We also present a Gemini Planet Imager H-band polarimetric image of the HD 131488 debris disk. We search for fundamental CO absorption lines in the iSHELL spectra of HD 32297, but do not detect any. We place an upper limit on the CO column density of ∼6 × 1015 cm−2. By combining the column density upper limit, the CO mass measured with the Atacama Large Millimeter/submillimeter Array (ALMA), and the geometrical properties of the disk, we estimate the scale height of the CO to be ≲2 au across the radial extent of the disk (∼80–120 au). We use the same method to estimate the CO scale height of three other edge-on, CO-rich debris disks that all have CO observed in absorption with the Hubble Space Telescope as well as in emission with ALMA: β Pictoris, HD 110058, and HD 131488. We compare our estimated CO scale heights of these four systems to the millimeter dust scale heights and find that, under the assumption of hydrostatic equilibrium, there is a potential correlation between the CO and millimeter dust scale heights. There are multiple factors that affect the gas vertical structure such as turbulence, photodissociation with weak vertical mixing, as well as where the gas originates. One possible explanation for the potential correlation could be that the gas and dust are of a similar secondary origin in these four systems.
Evidence for a Compact Stellar Merger Origin for GRB 230307A From Fermi-LAT and Multiwavelength Afterglow Observations
Authors: Dai Cui-Yuan , Guo Chen-Lei , Zhang Hai-Ming , Liu Ruo-Yu , Wang Xiang-Yu
Published: February 2024

GRB 230307A is the second-brightest gamma-ray burst (GRB) ever detected over 50 yr of observations and has a long duration in the prompt emission. Two galaxies are found to be close to the position of GRB 230307A: (1) a distant (z ∼ 3.87) star-forming galaxy, located at an offset of ∼0.″2–0.″3 from the GRB position (with a projected distance of ∼1–2 kpc); (2) a nearby (z = 0.065) spiral galaxy, located at an offset of 30″ (with a projected distance of ∼40 kpc). Though it has been found that the brightest GRBs are readily detected in GeV emission by the Fermi Large Area Telescope, we find no GeV afterglow emission from GRB 230307A. Combining this with the optical and X-ray afterglow data, we find that a circumburst density as low as ∼10−5–10−4 cm−3 is needed to explain the nondetection of GeV emission and the multiwavelength afterglow data, regardless of the redshift of this GRB. Such a low-density disfavors the association of GRB 230307A with the high-redshift star-forming galaxy, since the proximity of the GRB position to this galaxy would imply a higher-density environment. Instead, the low-density medium is consistent with the circumgalactic medium, which agrees with the large offset between GRB 230307A and the low-redshift galaxy. This points to the compact stellar merger origin for GRB 230307A, consistent with the detection of an associated kilonova.
Description of a new species of the Petrolisthes galathinus complex from the Caribbean Sea, and resurrection of Petrolisthes occidentalis from the East Pacific (Crustacea, Anomura, Porcellanidae)
Authors: Hiller Alexandra , Werding Bernd
Published: February 2024

The Petrolisthes galathinus complex currently consists of six American species distributed in the West Atlantic, including the amphi-American P. galathinus. All species in the complex are similar in their adult morphology but differ in colour, size, larval morphology, and shape of the adult sternal plate. The West Atlantic species have different geographic ranges, which overlap in the southern Caribbean. Previously published molecular data support the monophyly of the complex, and the reciprocal monophyly of each described species and further clades corresponding to different colour morphs. Here, the morph P. caribensis “Blue” is described as Petrolisthes coeruleussp. nov., and Petrolisthes occidentalis is formally resurrected for the Pacific individuals of P. galathinus. By adding these two species to the P. galathinus complex, this now consists of eight species. Colour illustrations of all species and colour morphs are provided and their geographic distributions and ecological ranges are discussed and updated.

Éthiques inclusives en éducation
Authors: Lahanier-Reuter Dominique
Published: February 2024

Les orientations dans les filières de l’enseignement spécialisé en France s’appuient explicitement sur des critères de retard des élèves, qu’il s’agisse de retard dans le développement ou de retard dans les apprentissages scolaires. Mais ces orientations touchent très majoritairement des élèves dont les familles sont en situation de grande pauvreté ou précarité. Le mouvement ATD Quart-Monde a engagé une recherche sur ce qui apparaît donc davantage comme des exclusions du parcours ordinaire que des processus d’inclusion dans le système scolaire. Nous montrons ici que cette hypothèse se trouve confortée par l’étude de discours d’enseignants sur ces orientations massives d’élèves de familles très défavorisées.

Creating Collective Identity: Geek Theatre, Fringe Festivals, and Fan Audiences
Authors: Storey Scout
Published: February 2024

Fringe Festivals and Geek Theatre share a plethora of affinities: both have penchants for generating offbeat and experimental theatre as labors of love on shoestring budgets, attracting quirky subcultural audiences made up of theatregoers and newcomers alike, and creating a sense of community based on values of egalitarian access to self-expression. Geek Theatre manifests in an intersection between the affinity spaces of fandom and the live experience of staged theatre, facilitating a uniquely community-based affective experience in which artists and audiences share a common language and love for the geeky genres of their subject matter. The history of Geek Theatre is embedded in Fringe culture, which I argue is the perfect incubator for its campy aesthetic and dialogic relationship between production and fan audience.

Published: February 2024

Advancing diversity in STEM requires competent and confident faculty and staff who can lead local professional development in inclusive teaching to improve classroom instruction and support all learners. This article examines how a facilitator training model designed to promote inclusive facilitation impacted the self-reported confidence and practices of inclusive learning community facilitators. This mixed methods study reports on survey data from project-trained facilitators (n = 71) collected over four course runs. Facilitators reported significant increases in confidence, with the largest effect sizes in areas related to diversity, equity, and inclusion (DEI) and identity. Qualitative findings indicate the training model effectively aligned facilitators with our approach to inclusive facilitation. Findings demonstrate that professional development in inclusive teaching, and by extension in other equity and diversity topics, can be successfully done at a national scale by centering identity, power, and positionality while upholding “do no harm.” This article provides a strategy for how DEI-focused faculty development efforts can select, train, and support facilitators on a national scale while maintaining high fidelity to project values and goals.
Reflections on White Marble at Labraunda
Authors: Freccero Agneta
Published: February 2024

The aim of this paper is to discuss white marble used for architectonic elements and statuary in the Labraunda Sanctuary.1 The buildings on the site date from three main periods: Hekatomnid, Roman Imperial, and Late Antiquity. White marble pieces with widely different characteristics were identified during examination and conservation. Some were coarse or medium-grained of a warm white hue; others were fine-grained of a cold white hue, grey-veined or in a variety of greyish nuances. One area of interest was the marbles’ provenance and how marble trade in the region was conducted, especially during the Hekatomnid period. Another area of interest was whether distinctive types could be associated with the respective periods or whether the choice of marble was related to types of object, in this case architectural elements and statuary. A set of scientific methods were applied on a number of samples. The results showed that marbles quarried during the Hekatomnid period mainly came from Herakleia on Latmos; that marble quarried during the Roman Imperial period was brought from quarries at Mylasa and elsewhere; and that marbles found on the site were reused during Late Antiquity. Subsequent tests indicated that the type of marble used related to a specific period rather than to a specific type of artefact.

Authors: Jain Gyanesh , Kumar A. V. Senthil , Kalyani Sushil , Chaturvedi Ankita
Published: February 2024

COVID-19 impacted the whole world's economy at large and all the sectors except a few. Most industries witnessed huge losses in most countries, whether developing, developed, or undeveloped. The losses suffered by the major sectors catering to the economies typically affect all the ancillary service sectors also. The research attempts to look at the causality of stock returns and volumes within, using a dynamic Markov regime switching GARCH model to identify the changes in this relation pre and post COVID-19. The study finds a weak relationship between the real growth represented by GDP and stock returns pre and post COVID-19. The presence of structural breaks was evident from the observations and a positive result from the regime-switching models, which suggests that the perception of stock markets is not derived from the real GDP.

Several attempts have been made on the use of alternative material for constructionpurpose. This is to limit the exploitation of the natural resources and the need to engage onrenewable resources that can function adequately in road construction with minimal carbonfootprints. The main objective of this review is to consider the outcome of the suitability of wasteglass products in the construction of roads based on the existing studies. From the relevant literatureconsulted, it was discovered that waste glass powder has the capacity to improve the compressiveand tensile strength of asphalt mix. Also, it has lower water absorption rate, thereby making itimpossible for the penetration of the chloride ions which usually accelerate road degradation. Inaddition to this, it improves the workability of the concrete used for the pavement construction,hence, it is more advantageous when compared with sand. The findings from this study will help theconstruction industry on the methods of waste glass recycling and its adoption into roadconstruction.
Utilization of Macadamia nut oil as a feedstock for a Sustainable Biodiesel Production

Published: February 2024

Although fossil fuel continues to play a dominant role in global energy system unfortunately their life span is threatened as the fossil reserves are running out. Except for the fact that they are readily available, tried and tested, unfortunately they bring about a negative environmental and climate impact. When the fossil fuels are burned, they produce both carbon dioxide and carbon monoxide which is the largest driver of global climate change and air pollution. This has caused a need to explore and transition to a cleaner and renewable energy resource like biofuel. Biofuel is a combination of fatty acid alkyl esters achieved by the esterification and transterification of triglycerides that can either be animal fats and vegetable oil with methanol and ethanol. Biodiesel provides several positive benefits by helping in decreasing the country’s dependence on the importation of crude oils, it also reduces the greenhouse gas emissions and advances the lubricating property. Biodiesel is produced and deployed globally with China being the country with the highest biofuel capacity in the world, with nearly 29.8 gigawatts as of 2021. It is followed by Brazil which is ranked second, with a biofuel capacity of 16.3 gigawatts. The selection of a feedstock in biofuel production has a noticeable impact as it determines if a biofuel will be formed or not from the transesterification process performed. The fatty acid / triglyceride content especially the Mono-Unsaturated Fatty Acids (MUFA’s) are of interest. The higher the MUFA’s, the higher possibility of a successful transterification hence biofuel being the by-products/formation with less catalyst and alcohol used. Feedstocks with over 40% fatty acids, especially the MUFA’s are favorable for biodiesel formation. Almost 80% of Macadamia’s fatty acids (MFAs) are palmitoleic acids (C16:1; ~20%) and Monounsaturated, mostly oleic (C18:1; ~60%). This study reviews the preparation of biofuel utilizing Macadamia nut oil (MNO) as a feedstock for sustainable biodiesel Production.

In this century, sustainability has become an essential element in any project to ensure a safe environment. The conversion of waste materials is an important step towards achieving sustainability. Moreover, converting these materials into adsorbents to treat wastewater shows great potential, especially due to its cost-effectiveness and the reduction of solid waste disposal. This research study aims to investigate the removal of Copper (Cu) from wastewater using waste tyre-recycled carbon black (WT-rCB) and modified waste tyre-recycled carbon black (WT-dAC) to determine their adsorption capability. The removal of Copper using WT-rCB and WT-dAC were investigated with various parameters: pH value, adsorbent dosage, and contact time. The chemical-physical activation process was employed to produce the WT-dAC. First, WT-rCB was impregnated with 1:5 wt% of 1 M KOH solution, then physically activated at 650 °C for 1 hr with flowing Nitrogen gas at 1 L/min. The adsorption study observed a removal efficiency of up to 65% using WT-dAC, while WT-rCB showed a removal efficiency of 22% under the optimum conditions. Eventually, the study demonstrates the employability of WT-dAC in the removal of Copper (Cu) from wastewater.

Demands for energy are rising as the world's population expands. To meet these demands, fossil fuels have been overused, yet this over reliance on them has led to their depletion. The usage of fossil fuels has also significantly contributed to the release of greenhouse gases, which is a serious environmental concern. Sustainable energy is therefore environmentally friendly and financially sound. Petro-diesel can be replaced by biodiesel because it is biodegradable and less hazardous. Biofuel is any fuel produced from biomass, which can be either animal fats or waste, plant or algae material as a feedstock. Biomass benefits in producing fuels which helps to lessen the demand for petroleum fuel and products. Petroleum fuel and gas increase the greenhouse gas emissions profile of the transportation sector. The Republic of South Africa (RSA) is the 14th world's largest emitter of greenhouse gases. This is due to the emissions resulting from burning and heavy reliance on coal. Since biofuel can be produced domestically from natural sources like soybeans, rapeseed, macadamia nuts, coconuts, and even leftover cooking, it has the potential to serve as a remarkable substitute for the commonly used petroleum-derived diesel fuel. This study addresses the historical development of macadamia nuts with a focus on the South African Macadamia Nuts (SAMN) industry, its origin, and as a feedstock for biodiesel production. The generation and classification of biodiesel, physicochemical properties, biodiesel standards, and both American Society for Testing and Materials (ASTM), European Committee for Standardization (EN 14214), and South African biodiesel framework standards are discussed. Furthermore, the biodiesel blending requirements, techniques, and benefits were outlined. Finally, the biodiesel regulatory framework of SA and biodiesel framework as per the Biodiesel Task team (BTT) was examined.

The presence of heavy metals in water resources brings hazard to health and the environment considering that most of these cannot be degraded and may result in bioaccumulation in the food chain. This study investigated the applicability and efficiency of waste eggshells for the removal of Copper (Cu) heavy metal in aqueous solution. The mixed-matrix membrane with polyvinylidene fluoride (PVDF) as membrane material, N-Methyl-2-pyrrolidone (NMP) as solvent and waste eggshell as additive with ratio of (a) 15:85:0, (b) 14.9:85:0.1, (c) 14.7:85:0.3, (d) 14.5:85:0.5 and (e) 14:85:1 is fabricated using phase inversion method. Phase inversion is a well-studied immersion precipitation technique for membrane synthesis. Using this common method, polymer is dissolved in an organic solvent and the solution cast upon a glass surface with 0.40 knife gap. The resulting membrane morphologies were analysed by using Scanning Electron Microscopy (SEM) and the significant functional group of the resulting membranes were identified using Fourier Transform Infrared Spectroscopy (FTIR). The addition of waste eggshell to the casting solution improved the morphology and structure of the membrane significantly. The appearance of waste eggshell on membrane surface demonstrated in SEM and FTIR analysis. Furthermore, the result of the study showed that the waste eggshells as an adsorbent could remove Cu in an aqueous solution up to 99% with water permeability of 56.52 Lm-2h-1bar-1. Overall, the study demonstrated that the waste eggshell that is generally considered as wastes in large quantities could become an economically advantageous for Cu removal.

This paper aims to investigate the effects of adding and increasing the concentration of halloysite nanotube (HNT) to a cellulose acetate (CA) membrane which is produced through non-solvent-induced phase separation via hand casting. Different characterization tests are performed on the nanocomposite samples: Scanning Electron Microscopy (SEM), Atomic Force Microscopy (AFM), Fourier Transform Infrared Spectroscopy (FTIR), and Atomic Absorption Spectroscopy (AAS). The addition of the filler itself increases the presence of peaks and valleys on the surface of the nanocomposite membrane. The 5% HNT nanocomposite membrane has the largest peaks and valleys-both in size and number. Using the following contact times: 2, 4, and 6 hours, the adsorption capacity of the CA-HNT membranes is obtained with the aid of AAS results. The 5% HNT sample leads to a nanocomposite membrane with a higher adsorption capacity relative to that of a pure CA membrane.

Introduction: Knee osteoarthritis is a highly prevalent musculoskeletal condition that causes chronic pain and psychological distress. The biological aspects of arthritis pain can be effectively managed with medication, physiotherapy and surgical procedures. However, no known psychological interventions to manage the psychological aspects of chronic pain have been developed in Sri Lanka.Objective: The study aimed to develop a culturally relevant integrative group psychological intervention for patients with chronic knee osteoarthritis pain.Methods: The first phase involved a literature review of existing psychological interventions on chronic pain management, which was used to develop a culturally relevant group psychological intervention named as “MyKOA-Cope: Psychological intervention for chronic knee osteoarthritis”. In the second phase, a Delphi study and a focus group discussion were conducted to evaluate the feasibility of the newly developed intervention.Results: The MyKOA-Cope is a six-session, in-person group intervention that lasts 45-50 minutes per session. These sessions include: 1) orientation to the intervention; 2) relaxation training; 3) exercise and pacing; pleasant activity scheduling; 4) identify negative automatic thoughts; 5) cognitive restructuring and calming selfstatements and 6) termination and maintenance strategies.Conclusion: The present study developed a culturally appropriate psychological intervention to enhance paincoping skills among patients with chronic knee osteoarthritis. This intervention has the potential to address the psychological aspects of chronic pain and contribute to the biomedical model. Future research can validate and tailor the MyKOA-Cope to suit the needs of patients with different illness conditions, literacy levels, and those who speak in Tamil in Sri Lanka.

Over-usage and unsafe usage of mobile devices can affect the sleep negatively. This study was conducted among Sri Lankan doctors using an online questionnaire to assess their practices. Evidence from 633 doctors in this study showed, majority of 494 (78%) takes the phone to the bed when going to sleep and 403 (63.7%) used to watch at them at least 10 mins prior to sleep. The usage of effect minimizing options like blue-light filter, low / autoadjustable brightness and dark theme were used only by 227 (35.9%), 384 (60.7%) and 201 (31.8%) participants, respectively. This highlighted the importance of increasing awareness.

Published: February 2024

Leptospirosis is a zoonotic illness with a wide range of organ involvement. We present a case of anicteric leptospirosis in a middle-aged man with numerous cervical lymphadenopathies, which, to our knowledge, has not been reported before in Sri Lanka. Excisional lymph node biopsy revealed reactive lymphadenitis. After ruling out other possible differential diagnoses, concurrently, serology confirmed the leptospiral bacteria as the etiology.

Purpose: The management of infertile patients with unilateral subclinical varicocele (SCV) and contralateral clinical varicocele (CV) remains controversial. We aimed to evaluate the effect of untreating SCV on the outcome of contralateral clinical varicocelectomy in infertile patients with oligoasthenozoospermia (OA). Materials and methods: Infertile patients with the diagnosis of OA who underwent left varicocelectomy were retrospectively evaluated. While all patients in the study had left clinical varicocele (LCV), some patients had concomitant right SCV. Patients were divided into two groups according to the presence or absence of a right SCV accompanying LCV as group 1; (LCV n = 104) or group 2; (LCV with right SCV, n = 74). Patients were evaluated with spermiogram parameters, pregnancy rates and serum levels of follicle stimulating hormone, luteinizing hormone, total testosterone at the first year of the follow-up. Results: The mean sperm concentration increased significantly in both groups. However, group 1 showed significantly greater improvement than group 2. The ratio of progressive motile sperm in group 1 was increased significantly whereas no significant change was shown in group 2. Both the spontaneous pregnancy rate and the pregnancy rate with ART were statistically lower in the group of patients with right SCV. No statistically significant difference was detected in serum hormone levels in both groups after varicocelectomy operations. Conclusions: Untreated right SCV may have adverse impact on the outcomes of left clinical varicocelectomy. In this context, the right testis can be considered in terms of treatment in patients with right SCV accompanying left CV.

The restricted quantum double of the Yangian
Authors: Wendlandt Curtis
Published: February 2024

Let

$\mathfrak {g}$

be a complex semisimple Lie algebra with associated Yangian

$Y_{\hbar }\mathfrak {g}$

. In the mid-1990s, Khoroshkin and Tolstoy formulated a conjecture which asserts that the algebra

$\mathrm {D}Y_{\hbar }\mathfrak {g}$

obtained by doubling the generators of

$Y_{\hbar }\mathfrak {g}$

, called the Yangian double, provides a realization of the quantum double of the Yangian. We provide a uniform proof of this conjecture over

$\mathbb {C}[\kern-1.2pt\![{\hbar }]\!\kern-1.2pt]$

which is compatible with the theory of quantized enveloping algebras. As a by-product, we identify the universal R-matrix of the Yangian with the canonical element defined by the pairing between the Yangian and its restricted dual.
