Abstract
We present the initial sample of redshifts for 3839 galaxies in the MeerKAT DEEP2 field—the most sensitive ∼1.4 GHz radio field yet observed with σ

n
= 0.55 μ Jy beam−1, reaching the confusion limit. Using a spectrophotometric technique combining coarse optical spectra with broadband photometry, we obtain redshifts with σ

z
≲ 0.01(1 + z), as determined from repeat observations. The resulting radio luminosity functions between 0.2 < z < 1.3 from our sample of 3839 individual galaxies are in remarkable agreement with those inferred from previous modeling of radio source counts, confirming a ≳50% excess in radio-based star formation rate density (SFRD) (z) measurements at 0.2 < z < 1.3 compared to those from the UV–IR. Several sources of systematic error are discussed—totalling ∼0.13 dex when added in quadrature. Even in the event that all systematic errors work to decrease the radio-based SFRD values, they are incapable of reconciling differences between the radio-based measurements with those from the UV–IR at 0.5 < z < 1.3. We conclude that significant work remains to have confidence in a full accounting of the star formation budget of the Universe.
Thermal Oxidation Reaction between NH3 and O3: Low-temperature Formation of an
NH4+
-bearing Salt
Authors: Tribbett Patrick D. , Loeffler Mark J. 
Published: May 2024

Abstract
NH3 has long been predicted to be an important component of outer solar system bodies, yet detection of this compound suggests a low abundance or absence on many objects where it would be expected. Here, we demonstrate that a thermally driven oxidation reaction between ammonia (NH3) and ozone (O3) in a H2O + NH3 + O3 mixture may contribute to the low abundance of NH3 on some of these objects, as this reaction efficiently occurs at temperatures as low as 70 K. We determined the overall activation energy for this reaction to be 17 ± 2 kJ mol−1, which is consistent with other chemical systems that react at cryogenic temperatures. The loss of these two compounds coincides with the formation of

at low temperatures, both of which are observable with infrared spectroscopy. Warming our H2O + NH3 + O3 mixtures through sublimation, we find a number of higher-temperature phases, such as ammonia hemihydrate, nitric acid, and ammonium nitrate (NH4NO3). The most stable of these is NH4NO3, which remains on the substrate until temperatures near 270 K. The salt product within this sample contains near-infrared spectral features between 2.0 and 2.22 μm, which is a spectral region of interest for several outer solar system objects, including the Uranian satellites Miranda, Ariel and Umbriel, and Pluto's satellite Charon.
Sharing data, caring for collections. Open data on collection agents affiliated with the Museum für Naturkunde Berlin
Authors: von Mering Sabine , Stolze Erik , Kaiser Katja , Petersen Mareike 
Published: May 2024

Linked open data on collection agents contribute to increased discoverability, accessibility and transparency of natural history collections. Despite major efforts to digitise and open up museum and university object collections, related information is often stored in internal resources. This paper describes a project conducted at the Museum für Naturkunde Berlin (MfN) contributing to its collection disclosure and development initiatives. Information on historical collectors and other collection agents was transferred from the internal MfN collector wiki to Wikidata. For a total of 600 collection agents, existing Wikidata items were enriched or new items created.
Special emphasis was put on linking these people to the Museum, to document their affiliation with the MfN, its collection and its archive. Within the project, an open participatory approach was taken. Several Wikidata edit-a-thons were organised to test this collaborative and innovative format for possible future application by the Museum. By opening up institutional silos and openly sharing data on agents connected to museum holdings, these data become more widely accessible and reusable, for example, as a resource for transdisciplinary provenance research.
Horatio’s ‘mote’: mining a metaphor in Q2 Hamlet
Authors: Walsh Brian 
Published: May 2024

Horatio compares the Ghost to a ‘mote’ that ‘trouble[s] the mind’s eye’ in the first scene of Hamlet, in a speech unique to the second quarto (1604). In this exercise in micro-analysis of a single line from Hamlet, I assess how this pithy metaphor helps create the texture of Q2’s version of the opening scene. Un-editing — or, more properly here, un-conflating — can help us realize something valuable about Q2 Hamlet, namely, that its opening scene does more than the opening scenes in Q1 or F to emphasize self-reflection and interiority as major themes. Further, Horatio’s pregnant comparison makes the figure of Old Hamlet morally ambiguous from the start by associating his appearance with feelings of guilt.
‘Hyperion’s curls, the front of Jove himself’ (3.4.56): mythological portraits in Hamlet’s closet scene
Authors: Lafont Agnès 
Published: May 2024

The article shows how Renaissance humanism — the rediscovery of classical learning — is dramatised in Hamlet to pit an idealised past against a corrupted present. It focuses on the ‘closet scene’ (3.4), that, for the benefit of Gertrude’s eyes — and the audience’s —, represents Hamlet’s father, a solar king, against Hamlet’s ‘father’s brother’, a satyr, in a vivid stage image that echoes Hamlet’s line in a previous soliloquy: ‘So excellent a king, that was to this / Hyperion a satyr’ (1.2.139-40). Such contrasting mythological portraits question Gertrude’s refusal to grieve her spouse until then, even suggesting a matricidal impulse in Hamlet.
Du délire d’Ophélie (IV.v) au récit de Gertrude (IV.vii) : théâtralisation de la fragmentation, esthétique de la recomposition
Authors: Drouet Pascale 
Published: May 2024

« La folie, c’est le déjà-là de la mort » : tout se passe comme si la célèbre formule de Michel Foucault trouvait son illustration parfaite dans le Hamlet de Shakespeare. En mettant en regard les propos décousus d’Ophélie (IV.v) et le récit de sa noyade par Gertrude (IV.vii), deux moments indissociables au point de former un véritable diptyque, on examinera la façon dont la folie se donne à voir et à entendre sur la scène élisabéthaine, convoquant à la fois confusion, fragmentation et subversion, puis on s’interrogera sur l’esthétique de la recomposition qui informe le récit de Gertrude et fait d’Ophélie ce que Gaston Bachelard a appelé « une image fondamentale de la rêverie des eaux » qui n’a cessé d’inspirer peintres et poètes.

Abstract

Background and Aims:
No studies have compared the effects of ketamine and dexmedetomidine on bowel recovery. We evaluated the effects of intraoperative low-dose ketamine or dexmedetomidine infusion on postoperative bowel recovery in patients undergoing gastrointestinal (GI) malignancy surgeries.

Material and Methods:
This placebo-controlled, randomized study was carried out in 84 American Society of Anesthesiologists II patients, aged 18–70 years, of either gender, undergoing elective open GI malignancy surgeries. Patients received intraoperative infusion of ketamine @ 0.1 mg kg-1 h-1 (KET), dexmedetomidine @ 0.25 μg kg-1 h-1 (DEX), or normal saline (placebo). Primary outcome was the time to first flatus and/or stool. Secondary outcomes included time to extubation, total analgesic requirement, postoperative pain scores, time to feeds, duration of intensive care unit (ICU) and hospital stay, and the incidence of adverse events. Continuous data were analyzed by the one-way analysis of variance (ANOVA) or the Kruskal–Wallis test. Categorical data were analyzed by the Chi-square test or the Fisher’s exact test.

Results:
Median time to passage of flatus and/or stool was 3 [interquartile range (IQR) 2–3] days in the KET group, 2 [IQR 2–3] days in the DEX group, and 2 [IQR 2–3] days in the placebo group (P = 0.53 for placebo vs. KET, 0.81 for placebo vs. DEX, and 0.99 for KET vs. DEX). Pain scores and analgesic consumption were significantly less in the intervention groups versus placebo (P < 0.001). No difference was seen in other secondary outcomes.

Conclusion:
Low-dose ketamine or dexmedetomidine did not result in early bowel recovery despite lower pain scores and opioid consumption in patients undergoing open GI malignancy surgeries.

Authors: Espesor Michael 
Published: May 2024

This study aimed to assess the status of the financial well-being of the public-school teachers in Tambler District and was designed to develop a proposed intervention program to address concerns on the financial well-being of the teachers. This study employed a cross-sectional survey which involved 186 teacher-respondents from five schools. A survey questionnaire was used to gather data from the sample which contained the demographic and financial profile, and a descriptive survey using a five-point Likert scale. The study revealed that the financial well-being of the teacher-respondents was somewhat good as they were confronted with financial constraints that alleviated their financial security and stability. Further, an intervention program in terms of improving the financial well-being of the teachers was developed in the study.<p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/soc/0717/a.php" alt="Hit counter" /></p>
THE EFFECT OF DIGITAL DRAMA ON EFL STUDENTS’ SKILLS IN THE INTERCULTURAL COMMUNICATION COURSE AT THE UNIVERSITY
Authors: Trang Ly Thi Minh 
Published: May 2024

<p>Intercultural communication is concerned with the sharing of information between different cultures and social groups, including individuals with religious, social, ethnic, and educational backgrounds. Cultural factors have a great impact on how people conduct diplomatic, economic, and educational activities in the era of international integration. The application of innovative methods in teaching Intercultural communication courses at universities is extremely necessary in order to break down cultural barriers and build awareness of cultural norms, as well as to enhance self-awareness, language skills and communication skills in a multicultural environment. At the same time, it helps learners to explore, preserve and promote the national cultural identity. The theatrical (drama) technique has been recognized as one of the powerful means of education and propaganda. One of the proposed methods is integrating drama in the context of digital transformation. This study aims to investigate the effectiveness of applying theatrical integration and online teaching tools via Zoom in teaching the Intercultural module to create a borderless cultural class. The quantitative method was conducted through experimental convention and questionnaires with the participation of students majoring in English at a university in the Mekong Delta, Vietnam. Specific steps have been taken to improve intercultural communication skills and intercultural interaction will enhance the ability to communicate and promote personal image as well as showcase national culture. The research has shown that using the digital drama model in the classroom as a teaching method not only helps learners academically but also provides knowledge about socio-cultural development.</p><p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/lit/0057/a.php" alt="Hit counter" /></p>

Published: May 2024

Concerns about the effectiveness of E-learning in education during the COVID-19 pandemic attracted substantial scholarly attention worldwide. Most of the studies identified the pandemic as a double-edged sword necessitating further scholarly debates. Even though these studies are instrumental in contextualising this topical issue, there is a disconcerting absence of such empirical studies in countries associated with vertical inequality, mostly those in the Global South. Cognisant of the contextual nature of technology and how actors and their interests intersect to shape how such technologies in their contexts maybe appropriated, this study assessed the effectiveness of E-learning during the COVID-19 pandemic, using the case study of a public university. It deployed the model of technology appropriation framework, the social justice theory, and qualitative interviews with 35 undergraduate students across faculties at the university. The findings indicated that just like in other higher education institutions (HEIs) in developing countries, the adoption of E-learning amid the COVID-19 lockdown acted as a double-edged sword. On one hand, online learning provided opportunities for some students, such as the convenience of learning at one's own pace and enhanced performance. On the other hand, empirical evidence demonstrates prevailing several challenges such as the digital gap among students, lack of ICT resources and lack of motivation and skills, inter alia. Thus, technical issues such as network, data and computer malfunctions, hindered the effective use of E-learning during the COVID-19 lockdown. While there are similarities on the challenges of E-learning between those documented in various parts of the world, it is important to acknowledge the differences based on local peculiarities. Going forward, we noted the need to adopt the 21st century pedagogical skills that promote collaboration, critical thinking and inclusivity, in teaching and learning in higher education.
Investigation of Iron Dissolution Mechanism in Acidic Solutions with and without Dissolved CO2—Part I: Electrochemical Impedance Spectroscopy Measurements

Aqueous CO2 corrosion of mild steel is one of the major problems in the oil and gas industry. While current understanding primarily focuses on cathodic reaction mechanisms, less attention has been given to the impact of aqueous CO2 on the anodic iron dissolution reaction. In contrast, the mechanism of iron dissolution in strongly acidic environments has been thoroughly investigated. Among the reaction mechanisms found in the open literature, a multipath mechanism was identified that could explain the iron dissolution in strong acidic sulfate solution; both in terms of steady-state polarization sweeps and impedance data at various pH values and current densities. However, the role of aqueous CO2 in solutions containing chlorides on the mechanism of iron dissolution remained an open question. The present study used electrochemical impedance spectroscopy (EIS) as the main technique, to study the mechanism of iron dissolution in strong acid chloride solution with and without the presence of CO2. Results showed that the presence of chloride ions (0.5 M) decreased the rate of iron dissolution by competing with hydroxide ions to adsorb on the metal surface, forming chloride-containing intermediate species that participate in the iron dissolution reaction. The resulting decrease in the availability of hydroxide intermediates, which are more effective at enhancing the reaction rate compared to chloride-containing intermediates, leads to an overall decrease in the rate of iron dissolution. While the presence of CO2 increases anodic current density, EIS investigation revealed that neither aqueous CO2 nor other carbonic species directly react on the bare metal surface to form adsorbed intermediates involved in the anodic reaction. EIS investigation suggested that aqueous CO2 may induce changes in the chemical composition of adsorbed species, rate constants, and surface coverage, thereby altering the kinetics of the underlying reactions.
