Enhancing Heat Transfer in Power Transformer Radiators via
Thermo-Fluid Dynamic Analysis with Periodic Thermal
Boundary Conditions
Authors: Dorella Jonathan , Storti Bruno , Rodriguez Gustavo Ríos , Storti Mario 
Published: November 2023

Abstract
The efficient dissipation of energy losses in electrical power transformers is crucial to prevent over-
heating of their windings and ensure proper functioning. In this study, we investigate the thermal
design of a 30 [MVA], 132/34.5/13.8 [kV] power transformer radiator operating in Oil Natural-
Air Natural mode, using Computational Fluid Dynamics (CFD) simulations. We introduce artificial
body forces in the momentum Navier-Stokes equation to analyze the thermo-fluid dynamic per-
formance of secondary transverse flows. Additionally, we propose a numerical scheme to solve the
thermal equation with periodic boundary conditions using a reduced length of the oil channel, allow-
ing for the decoupling of the thermal and fluid dynamic problems. To enhance the heat transfer,
we propose the use of turbulators and wall indentations arrangements. Through our simulations,
we analyze the effects of these enhancements on the cooling capacity of the transformer radiator.
Our results demonstrate that these modifications increase the heat transfer coefficient and improve
the cooling capacity of the radiator. Furthermore, we propose manufacturing considerations for
the turbulators and wall indentations arrangements to ensure their practicality. Our findings pro-
vide valuable insights into the thermal design of power transformer radiators and demonstrate the
effectiveness of turbulators and wall indentations arrangements in enhancing their cooling capacity.
(Not so) voluntary hospitalization as part of Zolpidem-induced complex sleep behaviour: A case report
Authors: Nayak Sriraksha R , Rao Suman S , N Karthik K , T Harsha G , Keertish Narayana 
Published: November 2023

Abstract
Background:
Since the approval of Zolpidem 26 years ago, 61 cases of Zolpidem-induced complex sleep behaviours have been reported to US FDA. Most of the complex sleep behaviours reported in these cases comprise of eating, walking, cooking, driving etc. during sleep and following the use of Zolpidem. Here is a case report of unique presentation of Zolpidem-induced complex sleep behaviour.
Case presentation:
A 44-year-old male with a diagnosis of recurrent depressive disorder on follow-up, reported waking up in the hospital with no recollection of how he got admitted. Following which, he got himself discharged against medical advice. Apart from the regular treatment, he was prescribed Zolpidem on as needed basis for insomnia.
On further probing, two similar instances of having sought discharge against medical advice after waking up in hospital, had occurred in the past. A thorough review of patient’s past prescriptions revealed that, all of these behaviors temporally correlated with the use of Zolpidem.
Conclusions:
This patient had shown a complex behaviour of hiring a cab to visit a Psychiatric hospital, interacting with the doctors and getting himself admitted. He also co-operated with the in-patient management until he regained awareness of his behaviour the next morning. The patient had shown three similar episodes of Zolpidem-induced complex sleep behaviour, all resulting in voluntary admission to a Psychiatric hospital.
All practitioners prescribing Z-drugs need to be aware of these rare, yet potentially serious adverse events and their forensic implications.
Modeling and Forecasting the Volatility of Some Industry Development Indicators in Ethiopia Using Multivariate GARCH Models

Published: November 2023

Abstract
Industry development indicators refer to a set of measures used to assess the performance and growth of industries. The main aim of this study was to assess the relationship between industry development indicators in Ethiopia using a multivariate GARCH model based on World Bank data from 1982 to 2021. A time series technique using annual data for the period 1982-2021 is utilized, and multivariate generalized autoregressive conditional heteroscedasticity was performed for volatility modeling.
The results of the diagonal BEKK (1, 1)-GARCH model showed that volatility is explosive; it means that the volatility of the development indicators is growing at an accelerating rate over time and potentially more extreme.
The implication of the study is that both domestic policymakers and development partners should support and motivate the growth of manufacturing sectors and manufacturing exports, since this is a necessary condition for promoting industry growth.

Abstract

Background Tricuspid regurgitation (TR) is common in patients evaluated by echocardiography. However, the prevalence and contributing factors of the disease remain limited. This hospital-based study was designed to analyze adult patients first diagnosed with tricuspid regurgitation by Doppler echocardiography to determine the prevalence and characteristics of clinically meaningful TR.Methods A total of 22,317 patients over the age of 18 who underwent echocardiography at the Cardiac Ultrasound Center of the First Affiliated Hospital of Guangdong Pharmaceutical University from July 1, 2015 to December 31, 2019 were collected. We collected basic information about the patients, including age, gender, history of heart disease, etc. Patients with valvular heart disease were assessed by transthoracic echocardiography. According to the degree of regurgitation and regurgitation, TR was divided into 6 grades (0–5). Pericardial effusion was recorded and bilateral atrial and ventricular diameters were measured. Logistic regression analysis was used to assess risk factors for significant TR (≥ grade 2 reflux).Results A total of 2299 significant TR cases were found in people over 18 years old, accounting for 10.3% of the total population. The occurrence of TR was found to be closely related to age. The prevalence rates of significant TR in different groups were: 3.3% in the younger than 45-year-old group, 4.1% in the 46-55-year-old group, 5.8% in the 56-65-year-old group, 10.1% in the 66-75-year-old group, and the prevalence of significant TR rose directly to 22.3% in patients over 75-year-old group. Further logistic regression analysis showed that male, age, pacemaker, congenital heart disease, pericardial effusion, pulmonary hypertension, mitral regurgitation, left ventricular diastolic dysfunction and aortic regurgitation were associated with the occurrence of significant TR. Both RVD and RA-1 were effective predictors of significant TR, with RVD ≥ 33.5 mm having a sensitivity of 0.638, specificity of 0.675, and ROC curve area of 0.722. The sensitivity of RA1 ≥ 45.5mm was 0.652, the specificity was 0.699, and the area under the ROC curve was 0.736.Conclusions TR is common in people undergoing echocardiography. Gender, age, pacemaker implantation, congenital heart disease, pericardial effusion, pulmonary hypertension, mitral insufficiency, and aortic insufficiency are the influencing factors of TR.
Fluid Boundaries: Ethnographic observations of co-located physiotherapists, chiropractors, and osteopaths
Authors: Toloui-Wallace Joshua , Forbes Roma , Thomson Oliver P. , Costa Nathalia 
Published: November 2023

Abstract

Background: Chiropractors, osteopaths and physiotherapists (COPs) assess and manage musculoskeletal conditions with similar manual or physical therapy techniques. This overlap in scope of practice raises questions about the boundaries between the three professions. Clinical settings where they are co-located may provide insight into the nature of these boundaries and how they are managed by clinicians themselves.
Objectives: To understand the nature of professional boundaries between COPs within a co-located clinical environment and describe the ways in which professional boundaries may be reinforced, weakened, or navigated in these environments.
Methods: Drawing from an interpretivist paradigm, we used ethnographic observations to observe interactions between 15 COPs across two clinics. Data were analysed using reflexive thematic analysis principles.
Results: We identified various physical and non-physical ‘boundary objects’ that influenced the nature of the professional boundaries between the COPs that participated in the study. These boundary objects overall seemed to increase the fluidity of the professional boundaries, at times simultaneously reinforcing and weakening them. The boundary objects were categorised into three themes: physical, including the clinic’s floor plan, large and small objects; social, including identities and discourse; and organisational, including appointment durations and fees, remuneration policies and insurance benefits.
Conclusions: Physical, social, organisational related factors made the nature of professional boundaries between COPs in these settings fluid. These findings may challenge consumers, clinicians and administrators to appreciate that traditional beliefs of distinct boundaries between COPs may not be so in practice. Both clinical practice and future research on professional boundaries between COPs may need to further consider some of these broader factors.
Exploring the Role of Central Bank Independence and Monetary Policy Communication in Achieving Price Stability
Authors: Natsagdorj Batjin 
Published: November 2023

Abstract

In modern monetary economics, the concepts of central bank independence and communication are crucial and contribute to the implementation of monetary policies. Various methods and indices have been developed to measure their impact on economic indicators and central bank performance. However, most studies have analyzed these separately, using indices with a restricted set of questions. This study investigated the effect of central bank independence and monetary policy communication on consumer price index-measured inflation deviation from the central bank target using a granular IAPOC index. The IAPOC index comprises 225 questions on three main pillars; this research employed two pillars (Independence & accountability and communications) with 182 questions. A fixed-effects panel regression analysis was performed in this study, utilizing primary data from Mongolia spanning 2007–2022, along with data from 19 other countries. The results suggest that effective communication and central bank independence are negatively correlated with inflation deviations from the target, supporting price stability.

Testing the applicability of GMPEs for the Hainaut region (Belgium) using intensity data
Authors: Vanneste Kris , Neefs Ben , Camelbeeck Thierry 
Published: November 2023

Abstract
In regions where strong earthquakes occurred before the deployment of dense seismic and accelerometric networks, intensity datasets can help selecting relevant ground motion prediction equations (GMPEs) for seismic hazard studies. This is the case for the Hainaut seismic zone, which was one of the most seismically active zones in and around Belgium during the 20th century. A recent reassessment of the intensity dataset of the area showed that intensities there attenuate much faster with distance than in other parts of northwestern Europe. Unfortunately, this characteristic has not yet been taken into account in current hazard maps for Belgium and northern France. Based on this dataset, we evaluate the goodness of fit of published GMPEs with intensities in Hainaut by means of a ground-motion-to-intensity conversion equation (GMICE) and according to different metrics (Likelihood, Log-likelihood and Euclidean-based Distance Ranking) published in literature. We also introduce a new measure to specifically evaluate the distance trend. Our results show that none of the tested GMPEs convincingly fits the intensity dataset, in particular the fast attenuation with distance. Still, applying the few GMPEs that show a reasonable fit in seismic hazard computations, we observe a decrease of the influence of the Hainaut seismicity in hazard maps for Belgium and northern France. This result is compatible with the earthquake intensity observations for the last 350 years in this part of Europe.
Regioselectivity Inversion in Hydroformylation of Aryl Alkenes with a
Diphosphoramidite-rhodium Catalyst
Authors: Arena Carmela G. 
Published: November 2023

Abstract:
Rhodium catalysts for hydroformylation of aryl alkenes generally promote the
formation of branched aldehydes. Here, we have demonstrated that by using a single rhodium
catalyst containing a diphosphoramidite ligand derived from BINOL, it is possible to
achieve the inversion of regioselectivity in the hydroformylation of aryl alkenes simply by
reducing the syngas pressure or, alternatively, increasing the reaction temperature. Indeed,
the hydroformylation of styrene carried out at 20 bar and 50°C resulted in 72% of 2-
phenylpropanal, while at atmospheric pressure, 71% of 3-phenylpropanal was obtained. A
similar linear selectivity (72-74%) was observed when the hydroformylation of styrene, pmethylstyrene,
and p-methoxystyrene was performed at 10 bar and higher temperature
(80°C). The regioselectivity of the hydroformylation of trans-β-methylstyrene under mild
conditions (80°C, 10-20 bar) was also strongly influenced by the syngas pressure. The results of this study show
that it is possible to reverse the selectivity of aryl alkenes hydroformylation with a single catalyst by simply exploring
the reaction conditions. In this paper, we have shown that the inversion of the regioselectivity in the hydroformylation
of aryl alkenes can be achieved using a single rhodium catalyst containing a BINOL-derived
diphosphoramidite ligand by reducing the syngas pressure or, alternatively, increasing the reaction temperature.

Authors: Pilehvar Shamim , Autoogar Marzieh , Hakemzadeh Faryar , Doostiiranid Amin , Moghadami Samar 
Published: November 2023

Background:
Endometrial scratching (ES) has been reported as a strategy to improve
the outcome of IVF. Considering that the follicular phase and luteal phase have their specific characteristics and hormonal secretions, we investigated whether scratching in different phases affects
a woman's chances of becoming pregnant following frozen embryo transfer.

Methods:
A total of 300 frozen embryo transfer candidate women with normal cavities and good
embryo quality were randomly divided into two groups: group A with ES in the follicular phase
and group B with ES in the luteal phase. In both groups, endometrial scratching was performed before IVF. The rate of pregnancy and baseline characteristics, such as age, education, and embryo
quality, were compared between the two groups.

Results:
Our results showed no significant differences in baseline characteristics between the
groups. Furthermore, no significant differences were observed between the women who underwent ES in the follicular phase and those in the luteal phase for the outcome of IVF and chemical
or clinical pregnancies.

Conclusion:
ES in different phases of the cycle preceding frozen embryo transfer did not affect
the outcome of pregnancy.
A Comprehensive Review on Patents, Herbal Treatment and Clinical
Trials on Acquired Immune Deficiency Syndrome
Authors: Choudhary Sushen Singh , Verma Sushma 
Published: November 2023

Abstract:
This paper provides an outline of the Human immunodeficiency virus (HIV), its mechanism of action, and types of HIV/AIDS. Additionally, it offers recent advances and patent data on
HIV medications and formulations for the last ten years. The HIV/AIDS patents describes how compounds can stop viruses from spreading and stop HIV from multiplying. It also gives information
about monolithic tablets, fixed oral doses of triple HIV formulations, and drug delivery systems that
use electrospun fibers. The patents also reveals the treatment for patients having liver disease by using herbal ingredients. The effects of various herbal ingredients and preparations on HIV replication,
immunological function, and symptom management have been researched. Despite the encouraging
randomized trial data available, it is crucial to proceed cautiously when using herbal treatments for
HIV/AIDS treatment. Recent years clinical trials of HIV/AIDS were also reviewed. Herbal remedies
are preferred more than other drugs because they have fewer side effects and have long-lasting effects
for the treatment of HIV/AIDS. The regulation, quality assurance, and standardization of herbal
products are the challenges for the industry.
Characterization of the Guinea Pig Production Chain in Southern Colombia and Identification of Determining Factors for Adequate Provision of Extension Services
Authors: Forero Oscar A. , Patiño Rocío E. , Carlosama Luz Dary , Portillo Paola A. 
Published: November 2023

The development of agrifood systems in Latin America reflects contrasting policy goals. Most governments advocate that “modernization,” measured as increased rates of technology adoption, is the way to address persistent food insecurity. By contrast, peasants’ and indigenous people’s organizations and social movements propose advancing knowledge co-production and co-innovation to increase the resilience of agrifood systems. Colombia reformed the National Innovation System for Agriculture in 2017. The policy reform instructed transitioning from providing “technical advice” to rural extension services. The research aimed to fill the knowledge gap regarding the transition to rural extension along the guinea pig production chain. In addition to characterizing the production chain, we conducted qualitative and reflectivity analyses to understand better how institutional practices and research cultures hinder or promote transitioning to rural extension. The investigation revealed that small-scale farmers who rely on the production and commercialization of guinea pigs as a livelihood strategy have continued receiving advice to adopt the latest technologies. In closing, besides addressing technological deficits or inefficiencies, a systemic approach that considers cultural context and identity must integrate into rural extension to ensure technological adoption is aligned with the sustainability and resilience objectives of the guinea pig production chain.

Published: November 2023

We started the Teach Your Parents project to explain the science behind climate change through comics in a child-friendly manner. The project team was my sister, Nandini Sundram (Grade 6), me, Abhimanyu Sundram (Grade 11) and our father, Sanjay Sundram. School-children after reading the comic created painting based on what they had learnt. Selected paintings were exhibited in an Art gallery in Ottawa. Over 700 children from India and Canada took part and the final exhibition was held from Feb to April 2024. We also exhibited robotics enabled pieces to further inform audiences about climate change.
The success of the project and its potential to create a social impact is exciting. We want to continue this initiative to reach larger audiences. We see collaboration between young people and adults as a way forward to fight climate change.
