Authors: Yogi Ramadhan  , Pratama Ananda  , Novita Anggraeni
Published: December 2024

Background: Anaphylaxis is a severe, life-threatening allergic reaction that can lead to cardiac arrest and hypoxic-ischemic brain injury (HIBI). Ketorolac, a nonsteroidal anti-inflammatory drug (NSAID) commonly used for postoperative pain management, has been rarely associated with anaphylaxis.
Case presentation: We present the case of a 32-year-old woman who developed anaphylaxis and subsequent cardiac arrest following intravenous administration of ketorolac after an appendectomy. Despite successful resuscitation, the patient suffered from HIBI and remained in a persistent vegetative state.
Conclusion: This report highlights the potential for fatal complications associated with ketorolac administration and emphasizes the importance of prompt recognition and management of anaphylaxis in the perioperative setting. This case underscores the need for heightened vigilance regarding potential anaphylactic reactions to ketorolac, even in patients with no prior history of drug allergies. Early recognition and aggressive management of anaphylaxis are crucial to minimize the risk of severe complications like cardiac arrest and HIBI.

A criação de codornas para produção de carne, ovos ou reprodução tem sido uma atividade promissora. Em meio a esta crescente exploração em relação a codornas de postura, a busca por trabalhos científicos que avalie as exigências nutricionais dessas aves são cada vez maiores, uma vez que suas exigências diferem de frangos de corte e galinhas poedeiras, bem como as de codornas japonesas são distintas de codornas europeias. Visando melhorias nos índices de produção de codornas japonesas em fase de postura, pesquisas são realizadas levando em consideração fatores nutricionais como níveis de energia metabolizável (EM) e lisina digestível (DLys) na dieta. A determinação dos níveis adequados destes nutrientes para máxima produção de ovos de codornas japonesa é importante para embasar as tabelas de exigências nutricionais para que se possa formular dietas de custo mínimo e máximo retorno econômico. Além disso, o ambiente em que o animal é produzido está entre um dos principais responsáveis por perdas na produção animal em escala industrial, onde o estresse térmico por altas temperaturas nas aves pode acarretar em diminuição dos índices de produtividade. Ingredientes alternativos com intuito de melhorar o crescimento, eficiência de utilização dos nutrientes da dieta na produção e a imunidade do animal submetidos a estresse têm estimulado o desenvolvimento de pesquisas baseadas em nutrientes que melhorem a função imune e digestiva dos animais, como é o caso da glutamina que tem sido tema de diversos estudos com aves e suínos, no entanto há uma escassez de trabalhos com codornas japonesas. Sendo assim, é importante investigar as aplicações da glutamina e os níveis de EM e DLys na dieta de codornas japonesas, e seus efeitos nas aves criadas em estresse térmico.

Engineering Laboratory IAQ Monitoring: A Real-Time Solution using Raspberry PI and Grafana Dashboard
Authors: Jethi Permesh Lal , Pin Fan Hau , Kumar Eriki Ananda
Published: December 2024

The World Health Organization (WHO) has reported that people who spent approximately 80 % - 90 % of their time being indoors daily, resulted in over 3 million premature deaths each year due to a disease caused by indoor air pollution. High concentration of indoor air pollutant such as particulate matter, carbon dioxide and imbalances between temperature and relative humidity have the potential to create unpleasant odour and dusty air, resulting in an incommodious environment and respiratory issues. The purpose of this project was to investigate the air quality at two engineering laboratories in a higher learning institution. A survey revealed that 41 % of students reported a bad odour in the workshop laboratory, while 38 % experienced the same issue in the Material & Automation Laboratory of the particular institution. Therefore, an IAQ (Indoor Air Quality) alert system was developed. The system consisted of sensors that measured the air quality, whereby data were continuously read and fed into a Raspberry PI controller by using a wireless communication device namely ESP-32. The controller has a smart card memory for logging purposes. The data were continuously read by a computer dashboard by using Grafana software. A beacon light was integrated with the controller to provide an alert indicator. Parameters measured were Particulate matter concentration, Carbon Dioxide level, Temperature and Humidity level. Measurement was done for three days while students were undergoing their activities in both laboratories. Data was benchmark with IAQ DOSH (Department of Safety & Health) and WHO (World Health Organisation). It was found that Particulate Matter in both laboratory and Workshop exceeded the IAQ limits, while the Carbon Dioxide reading was a concern. Temperature and Humidity were at acceptable levels but required constant monitoring.
Numerical Investigation of Squeezing Flow of Ternary Hybrid Nanofluid (Cu-Al2O3-TiO2/H2O) between Two Parallel Plates in a Porous Medium with Thermal Radiation and Heat Source/Sink
Authors: Agarwal Hemant , Chakraborty Shyamanta , Nath Rupam Shankar
Published: December 2024

This work aims to investigate the influence of thermal radiation on the magnetohydrodynamics squeezing flow of water-based ternary hybrid nanofluids between two parallel plates in a Darcy porous medium. The nanoparticles Cu, Al₂O₃, and TiO₂ are dispersed in a base fluid H₂O, resulting in the creation of a ternary hybrid nanofluid Cu-Al₂O₃-TiO₂/H₂O. This study examines the deformation of the lower plate as the upper one advances towards it. The numerical results are computed using the 3-stage Lobatto IIIa method, which is specially implemented by Bvp4c in MATLAB. The effects of various parameters are visually illustrated through graphs and quantitatively shown in tables. The velocity profile f'(η) shows a decrease in pattern when the parameters S and λ on the upper plate and Da on the lower plate are increased. Conversely, it displays an increasing pattern with higher values of Sq and λ on the lower plate, as well as Da on the upper plate. The absolute skin friction of the ternary hybrid nanofluid is seen to be approximately 5% higher than that of the regular nanofluid at both lower and upper plates. The heat transmission rate of the ternary hybrid nanofluid is higher at the upper plate compared to the lower plate.
Inside an outside broadcast with Goffman: Exploring radio personalities' performance and interaction in engaging radio broadcasting
Authors: Delport Mardi Christina
Published: December 2024

Radio stations conduct outside broadcasts to create awareness of their brands, promote their business clients’ interests, invest in their communities, and interact with their listeners. The outside broadcast is considered the most difficult form of radio broadcasting. Yet the experiences radio personalities encounter during outside broadcasts are under-explored in academic literature. This study explored the factors that impact positively and negatively on outside broadcast performance and interaction; and established the interplay between these two concepts. Data were collected through semi-structured interviews with eleven radio personalities at a central South African community radio station. The data analysis was driven by theory (Goffman’s dramaturgical model of social interaction) and a thematic content analysis. The findings suggest that outside broadcasts involve four finely tuned components that work in tandem to enable radio personalities to perform and interact in meaningful ways with their respective audiences. These are control of the setting, accessibility to performing zones, teamwork, and creative script. The recommendations for best practice may assist radio stations in connecting more meaningfully with their clients and listeners.
A golf course or grazing land: Using participatory communication as a conflict management tool in community development
Authors: Ponono Mvuzo , Notenga Nomzingisi
Published: December 2024

The question underpinning this study is why the Tyusha (Evelyn Valley) Development Project, a tourism project in South Africa’s Eastern Cape province, championed by developers, failed to materialise. The starting point of the research was whether, as the classic view suggests, the failure of the project was due to lack of community involvement. The interviews conducted indicated that participation was not the issue. The community had been consulted and were part of the wider formative discussions. What held the project back was conflict amongst the community (or project) leadership group. Given the economic potential of the project for a poor village like Tyusha, one would have expected greater cooperation between community members. This is especially the case when there is willingness and support from private capital and local government. Through a close reading of participatory development critiques, the article finds that conflict is part and parcel of community development work. With communication breakdowns in mind, which can impede project success, the article concludes that participatory development communication is a good vehicle to carry the dual mandate of community empowerment and mediation of conflict.

Authors: Reghunath Lakshmi , Zafar Shahila
Published: December 2024

This article reports on a bibliometric investigation of peerreviewed research articles on climate change reporting in the press, primarily in newspapers, from January 2013 to December 2023. The results indicate that while there has been a general increase in the amount of climate communication research, it is heavily tilted towards highincome countries in terms of the region of research focus and the host countries of the authors. Moreover, the discipline was found to be restricted in its discussion of public response and the influence of stakeholders in climate conversations. Additionally, the study points to an emerging pattern of interconnectedness between research on communication of global health  crises like Covid-19 and climate change. The study highlights an urgent need for diversity in accommodating voices from the Global South for more holistic growth of climate communication.

Published: December 2024

Social media has challenged the idea that mainstream media shapes the public, media, and policy agenda. The fragmentation of audiences and their selective consumption of content has challenged the traditional ideas of agenda-setting theory, as well as highlighted the influence of discourse. Fittingly, principles of the agenda-setting theory and discourse theory apply to this study which seeks to explore which discourse under #PutSouthAfricansFirst sets the public agenda for misperceptions and violence towards black African immigrants in South Africa. The study uses netnography and discourse analysis to assess purposively selected tweets under the #PutSouthAfricansFirst from June 2023 to July 2023, a period prone to xenophobic attacks in South Africa. The results indicated that crime, political rhetoric, strife for jobs, and dehumanisation are pivotal topics of the #PutSouthAfricansFirst xenophobic discourse inundating Black Twitter (X) in South Africa. It is these issues that appear to set the agenda among the public and in the media for negative perceptions and physical violence targeted at black African immigrants.
Public-private and community collaboration: A stakeholder communication case study of community-based tourism

By focusing on the perceptions and experiences of the Batlokoa owner community at the Witsieshoek Mountain Lodge in the Drakensberg, Free State, South Africa, this case study examines the collaboration between tourism companies, communities, and government departments. A stakeholder communication approach is applied within a reverse cultural studies analytical framework. The findings suggest that the lodge was viewed by the Batlokoa owners primarily as a place of employment and secondarily as a place of heritage. The study examines the many hurdles encountered, and how the decaying lodge became financially sustainable. This analysis draws on the case study of internal lodge communication and visioning that was conducted during a refurbishing phase led by a new hotel operator during 2010 to 2011 and which, updated to 2024, reveals clear community benefits and effective stakeholder communication. The lessons learnt from the early case study are contextualized for contemporary relevance.

Nowadays, promoting and intensifying the use of less polluting energy has received increased attention, to cover the carbon footprint, especially, due to the consumption of fossil fuels. In the transport sector, fuel requirements such as handling, safety issues, energy density, and onboard storage have confirmed that the liquid fuels will still dominate the near and mid-term future in application especially for high power density applications. Most research attention on alternative fuels has focused on the development of biofuels and the more direct approach for decarbonizing the fuel source based on hydrogen-enriched hydrocarbon fuels for a complete and efficient oxidation, in devices working by combustion process such air-breathing propulsion system and internal combustion engines. The latter shows a great potential in addressing environmental issues, considerable promise in terms of the key technical issues and improvement of fuel economy. In view of these points, hydrogen and hydrogen peroxide is promising fuels. An investigation is conducted to probe and compare the effect of H2 and H2O2 additions on the fundamental combustion characteristics of n-decane as a single component surrogate for jet fuel. It is found that the increased volumetric fraction of H2 and H2O2 as substituent to the removed partial fraction of air at varying equivalence ratios and pressures had an effect very interesting in some practical application for performance improvement with lower structure change, cost, consumption, and reduced pollutant emissions.
The Search for the In-betweeners: How Packed Are TESS Planetary Systems?

Published: December 2024

In this work, we examine seven systems discovered by TESS, to see whether there is any room in those systems for an additional planet (or several) to lurk unseen between the two planets already confirmed therein. In five of those systems (namely, HD 15337, HD 21749, HD 63433, HD 73583, and LTT 3780), we find that there is ample room for an undiscovered planet to move between those that have already been discovered. In other words, as they currently stand, those systems are not tightly packed. In stark contrast, the perturbative influence of the two known TOI-1670 planets is such that additional planets in between are ruled out. The final system, TOI 421, is more challenging. In the vast majority of cases, adding an Earth-mass planet to that system between the orbits of the known planets caused catastrophic instability. Just ∼1.1% of our simulations of the modified system proved dynamically stable on a timescale of 1 Myr. As a result, it seems that there is very little room between the two known planets in the TOI 421 system for an additional unseen world to exist, but the existence of such a planet cannot be definitely ruled out on dynamical grounds alone.

We report here the results obtained from a systematic optical photometric survey aimed at finding new compact binary millisecond pulsars (also known as “spiders”): the COmpact BInary PULsar SEarch. We acquired multiband optical images over 1 yr around 33 unidentified Fermi Large Area Telescope sources, selected as pulsar candidates based on their curved GeV spectra and steady γ-ray emission. We present the discovery of four optical variables coinciding with the Fermi sources 3FGL J0737.2−3233, 3FGL J2117.6+3725 (two systems in this field), and 3FGL J2221.6+6507, which we propose as new candidate spider systems. Indeed, they all show optical flux modulation consistent with orbital periods of 0.3548(5), 0.25328(6), 0.441961(2), and 0.165(4) days, respectively, with amplitudes ≳0.3 mag and colors compatible with companion star temperatures of 5000–6000 K. These properties are consistent with the “redback” subclass of spider pulsars. If confirmed as a millisecond pulsar, 3FGL J0737.2−3233 will be the closest known spider to Earth (

, from Gaia-DR3 parallax). We searched and did not find any X-ray sources matching our four candidates, placing 3σ upper limits of ∼1031–1032 erg s−1 (0.3–10 keV) on their soft X-ray luminosities. We also present and discuss other multiwavelength information on our spider candidates, from infrared to X-rays.

During routine survey imaging, the reactivated Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE-R) serendipitously caught the Type II supernova SN 2023ixf in Messier 101 on the rise, starting day 3.6 through day 10.9, and again on the decline at late times from days 211 through 213 and days 370 through 372. We have considered these mid-IR data together with observations from the ultraviolet (UV) through the near-IR, when possible. At day 3.6 we approximated the optical emission with a hot, ∼26,630 K blackbody, with a notable UV excess inferred to result from strong supernova (SN) shock interaction with circumstellar matter (CSM). In the IR, however, a clear excess is also obvious, and we fit it with a cooler, ∼1620 K blackbody with a radius of ∼2.6 × 1015 cm, consistent with dust in the progenitor’s circumstellar shell likely heated by the UV emission from the CSM interaction. On day 10.8, the light detected was consistent with SN ejecta-dominated emission. At late times we also observed a clear NEOWISE-R excess, which could arise either from newly formed dust in the inner ejecta or in the contact discontinuity between the forward and reverse shocks, or from more distant pre-existing dust grains in the SN environment. Furthermore, the large 4.6 μm excess at late times can also be explained by the emergence of the carbon monoxide 1–0 vibrational band. SN 2023ixf is the best-observed SN II in the mid-IR during the first several days after the explosion and one of the most luminous such SNe ever seen.
