Unlocking Grid Power for Drilling: Novel Power Management System Enables Rigs to Utilize Grid Power in Locations Previously Not Possible
Authors: van Wissenkerke M. Snijder , Barbee R. , Poludasu S. , Norris N.
Published: February 2025

Electrification of oil & gas facilities is a critical component in the industry's shift towards decarbonization. Power from the utility grid is less carbon-intensive than traditional on-site generation and offers additional benefits including cost savings and noise reduction. Many permanent facilities such as compression stations and producing wells now operate on grid power, often with a renewable energy component. Despite clear benefits, few drilling rigs have strayed from traditional diesel power to make the switch to the grid as the source of energy for drilling. As fields get more developed, it becomes increasingly difficult to access adequate power capacity for temporary facilities with variable demand such as drilling rigs. This paper introduces a new technology that greatly expands the feasibility of grid power for drilling by allowing rigs to utilize any amount of grid power available in conjunction with generators and battery energy storage.

This technology operates effectively due to custom hardware specifically engineered to integrate utility power, battery energy storage, and generators. The custom hardware comprises of switchgear and controls to parallel the utility feed with generators and battery energy storage. The automated system dynamically limits the power draw from the utility to stay within user-defined requirements and performs peak shaving by drawing power from battery energy storage and additional generators if necessary. When the power demand decreases below the grid capacity, the system continues to draw the maximum available power from the grid to recharge the battery energy storage. This system makes it viable to utilize grid power in locations that were previously infeasible.

Since the first implementation in 2023, this new technology has demonstrated the ability to seamlessly operate within utility grid limits without impacting drilling operations. Previously, only rigs with 4 to 5 Megawatts (MW) available would consider utilizing grid power. This technology has proven that most of the benefits can still be realized with only a fraction of available utility power. On locations with 2 MW available, the system reduced fuel consumption and carbon emissions by over 90% compared to traditional diesel rigs. Even on locations with only 1 MW available, the system reduced carbon emissions by over 50%.

This technology lays the foundation for the future development of distributed energy resources that can power all upstream and midstream facilities using a mix of on-site generation and permanent facilities such as wind and solar farms connected by a microgrid. By adopting a system where facilities can effectively control their grid power consumption, available power can be shared efficiently between consumers to create a network of smart, highly efficient assets.
A Multi-Faceted Approach for Mitigating High Frequency Torsional Oscillation for Motorized Rotary Steerable System Bottom Hole Assemblies
Authors: Nair V. N. , Zhang L.
Published: February 2025

The paper describes a systematic approach for mitigating High Frequency Torsional Oscillation vibration (HFTO) for a motorized rotary steerable system (RSS) through bottom hole assembly design (BHA), drill bit design and real time mitigation technology and processes. There have been various HFTO mitigation tools in the market utilized to mitigate HFTO however these tools may not fully complement the efforts if the system design is not optimal for the application.

The various production section motorized RSS BHA design configurations in the Permian Basin and design considerations to reduce HFTO vibration will be discussed in the paper. A methodology for comparing BHA stiffness models with HFTO vibration will be illustrated. HFTO vibration measurement methodology and effectiveness in real time is critical to apply mitigation strategies to reduce the HFTO vibration severity to prevent down hole tool failures. Bit design features should balance rate of penetration (ROP) performance while ensuring drill bit stability and efficiency for the planned application. Real time mitigation strategies are a critical step to a lower HFTO vibration severity signature.

The RSS tool measures HFTO at 1 kHz sampling rate and processes and records the mode frequencies and their magnitudes continuously and reports to surface in real time whenever high HFTO magnitude is encountered, making it possible to mitigate HFTO in real time. Field data has shown proper optimal stiffness configurations of the BHA components can effectively reduce the likelihood of certain damaging modes of HFTO from happening. Different drill bit designs and cutter technology were also tested and their effects on HFTO mitigation is analyzed. Real time operational mitigation of HFTO has been proven effective in most cases whereas in other cases the HFTO damage occurs too quick to mitigate. A few case studies are presented to show the effects on HFTO mitigation by combining BHA design, drill bit design, drilling parameter adjustment as well as downhole tool design. The paper also illustrates cases while utilizing different types of vibration mitigation tools in the BHA's however its effectiveness to mitigate high severity HFTO may be inconclusive on many situations because of other predominant suboptimal factors in BHA design, drill bit design and drilling practices.

The paper describes the planning and execution approach for applications with motorized RSS systems to minimize HFTO vibration related downhole tool failures and improve drilling performance. The different combination of technologies utilized to mitigate HFTO should continue to be analyzed. However, the variability in results may be because of several factors that need to be scrutinized further to derive consistent results. A multi-faceted planning and execution approach is essential to mitigate HFTO for drilling performance.
Autonomous Drilling Platform - An Enabler for Automated Steering Control and Remote Operations in the Permian
Authors: Gonçalves D. , Ferreira F. , Nair V. N.
Published: February 2025

The Autonomous Drilling Platform (ADP) revolutionizes directional drilling by allowing drillers to concentrate on performance-driven tasks rather than routine calculations and activities. The ADP enhances the communication workflow between geosteering and downhole rotary steerable steering settings by employing a systematic approach that integrates new targets, calculates feasible trajectories, and assesses their viability within the constraints of the well design. This seamless integration and automation significantly improve the drilling and steering efficiency of the directional drilling operations.

The innovative platform enables real-time wellplan updates, effectively bridging the communication gap between surface parameters, drilling engineering, with its tool limitations and downhole tools automation. The platform facilitates a dynamic and prompt response to changing subsurface conditions, thereby optimizing drilling efficiency and accuracy. The integration of automated calculations and synchronization between surface and downhole automation systems allows field engineers to focus on performance-oriented activities. ADP automatically downlinks the updated directional drilling settings to the downhole tools to execute the revised trajectory. It also provides operators with remote access via a web interface, enabling the monitoring of details pertaining to directional drilling operations from any location worldwide.

The ADP was implemented in phases for varying well complexity in the Permian operations in Midland and Delaware Basins. Consistent drilling performance has been a challenge due to inconsistencies in drilling practices, steering control and sub optimal drilling parameters for the target formations drilled. ADP enabled the execution team to focus on drilling performance with an interface that encompasses drilling parameters along with steering control recommendations. The integration of a data workflow enabled remote operations reducing personnel on site while experienced team members execute jobs remotely. With ADP implemented above 80% of the drilling interval showcased better drilling performance and service quality compared to similar complexity wells that had no ADP or lower utilization of ADP during job execution. This innovative platform not only optimizes the drilling process but also enhances safety and reduce costs, marking a new era in the field of directional drilling business

This paper describes the Autonomous Drilling Platform which represents a significant advancement in directional drilling technology. That is done by improving communication workflows, integrating automated calculations, and enabling remote operations. The ADP allows field engineers to concentrate on enhancing drilling performance and efficiency. As the industry continues to evolve, the ADP will play a crucial role in driving advancements and setting new standards for operational excellence.

This study contributes valuable insights to the discussion on innovation commercialization and offers practical advice for organizations facing the challenges of today’s market.
THE INTERNATIONALIZATION PROCESS OF A HUMANITIES JOURNAL: A CASE STUDY OF THE BRAZILIAN JOURNAL OF RURAL EDUCATION
Authors:   , ARAÚJO GUSTAVO CUNHA DE
Published: February 2025

The main objective of this research was to analyze the variables that contributed to the
internationalization process of the Revista Brasileira de Educação do Campo (Brazilian
Journal of Rural Education), between 2016 and 2023. This study adopted a qualitativequantitative approach, descriptive in nature and of the case study type. The main source of
data was the journal's own website, which uses the OJS system. Although the journal has
gained a foothold in the Latin American scientific scene, it still encounters limitations that
prevent its growth and consolidation in countries outside Latin America. It is understood that
the main difficulty concerns the lack of investment in Brazil for the development,
maintenance, and permanence of scientific journals, which leads to two important challenges:
the production of science in journals that have no (or little) funding for the development of
their work, and the expansion of articles published by Brazilian authors translated into other
languages (English and Spanish), who do not receive funding for their research.

Documentary of (De)Colonization
Authors: Johnson Samuel
Published: February 2025

This essay examines the linkage of epistemological inequities, social and ecological devastation, and ethnocide in the Ex-Pajé. This hybrid docudrama provides a vision of contemporary colonial encounters in the 21st century Amazon Rainforest through a mix of loosely connected fictional narratives, improvised scenes, and documentary footage. Ex-pajé is the product of a collaborative filmmaking effort between writer-director Luiz Bolognesi, “ex-pajé” Perpera Suruí, and members of the Paiter Suruí community. Bolognesi crafts a harsh critique of evangelism and the epistemicide confronted by indigenous communities of the Americas since the late 15th century. With Perpera Suruí as protagonist, this film visually and narratively reframes the colonial encounter from the perspective of an “ex-shaman” providing a meditative and visceral portrayal of coloniality that underscores the need for collaborative story making that centers resistance to the violences of the Modern/Colonial age.

Understandably, given its scope, the British periodical press has so far received the most attention, which is why Pazos-Alonso’s Francisca Wood and Nineteenth-Century Periodical Culture: Pressing for Change, with its focus on one nineteenth-century Portuguese magazine in the context of the Portuguese periodical landscape of the time, while simultaneously offering some connections to the British context, is such a welcome addition to the field.
A linguagem das flores
Authors: Augusto Barbosa Marlon
Published: February 2025

Esse texto pretende tecer alguns comentários sobre o filme Virgem Margarida (2012), do diretor Licínio Azevedo. O objetivo é mostrar que, ao recuperar a história das mulheres enviadas para os campos de reeducação e de alguns símbolos da revolução, Licínio Azevedo faz de seu filme um aparato de corte e de crítica: ele corta o corpo/conceito de nação que se deseja único, estabelecendo e identificando as contradições do movimento de pós-independência de Moçambique. Por um lado, havia a ideologia do projeto nacional socialista (FRELIMO) que libertava o povo da colonização, mas que, por outro, instituía campos de reeducação para “libertar” a mente colonizada. Assim, pretendo mostrar, seguindo considerações de Georges Didi-Huberman, que, para estabelecer esse corte, essa crítica, há uma espécie de desmonumentalização dos símbolos e um movimento de cores e superfícies.

O livro Caderno de memórias coloniais (2018), da escritora portuguesa Isabela Figueiredo, potencializa um exemplo da escrita como matriz estranha, pois sua gênese passa por uma construção digital, a partir do formato do blogue, até sua edição impressa no ano de 2009 pela editora portuguesa Angelus Novus. Trata-se de um caderno-romance que narra, por meio de técnicas ficcionais, a experiência da infância e parte da adolescência da escritora no passado colonial moçambicano. O objetivo deste artigo é propor maneiras de leitura que atravessem a categoria de caderno como inacabamento. À obra se adicionam fotografias e capítulos em edições posteriores, criando gestos que reforçam a narrativa das imagens como representação do passado colonial. Assim sendo, no avanço da curadoria editorial, as fotografias vão tomando existência material na história como elementosficcionais, permitindo um ludismo metarreflexivo e metanarrativo.
Salão Nobre | Salão Pobre
Authors: Beleza Barreiros Inês
Published: February 2025

Salão Nobre | Salão Pobre [Noble Hall, Poor Hall] is an image-memory aimed at unleashing the imagination and encapsulate a potentiality: what is yet not but could otherwise.1 It is a visual intervention into Portugal’s colonial archive, understood here as the law determining what can and cannot be represented.2 Such intervention is born out of a need to examine colonial “visuality” without reproducing its effects and eternalizing its spell in the present. It is part of a larger project of mine—a “visual archaeology”—a methodological critique, in which the image levies itself as the very object of its own deconstruction (Barreiros 2018).
Entre o dito e o escrito

Even today, when they are regaining more space in the media it remains a practice to assume that the lack of publications by women in general is a result of an alleged inactivity on their part instead of the existence of a system that controls and reduces the possibilities for them to gain access to privileged spaces. In the case of afro-Brazilian women the issue is exponentially complicated due to the legacies of slavery and racism. However, the absence of publications is not proof of idleness or meager artistic value. Women always produced artistic texts, even if they did not reach an established public.
“Alas! A Woman That Attempts the Lens”
Authors: Owen Hilary
Published: February 2025

In 2021, Margarida Gil’s debut longa metragem, Relação fiel e verdadeira was finally released on DVD by the Academia Portuguesa de Cinema, thirty-four years after it premiered. In 1987, it had met with a predominantly negative critical reception from the mainstream press, an unfortunate fate for a film that was not only pioneering for its subject matter and cinematography but was also Portugal’s first screen adaptation by a woman director of a female-authored text. This article explores some of the dominant questions surrounding the gender politics of Gil’s film and women’s position in Portuguese cinema culture in the early 1980s. I argue that the film reterritorializes the literary adaptation genre, which was a mainstay of national (male-authored) heritage on screen, not least through the ways in which Gil uses mirrors and reflections to install, and empower, a resistant and interrogatory feminine perspective in key images and scenes.
Deus-dará e As doenças do Brasil ou quando o desconforto na memória coletiva não pode ser bestseller
Authors: Rendeiro Margarida
Published: February 2025

O presente artigo analisa a receção a Deus-dará, de Alexandra Lucas Coelho, e a As doenças do Brasil, de Valter Hugo Mãe, à luz do conceito “sujeito implicado” de Michael Rothberg. Ao expor os laços genealógicos que unem Portugal e o Brasil no tempo longo da história colonial portuguesa, Deus-dará constrói um olhar implicado sobre as narrativas de memória coletiva. Argumenta-se que, ao contrário da receção académica, a receção não-académica portuguesa reverbera o desconforto coletivo perante a necessidade de nos reconhecermos enquanto sujeitos implicados na história e o estado de negação generalizado em Portugal perante rasuras seletivas nas narrativas de memória. Pelo contrário, a análise da receção não-académica a As doenças do Brasil reflete o acolhimento a uma narrativa que nem compromete o silêncio coletivo face aquelas rasuras seletivas nem o facto de as narrativas de memória colonial estarem assentes em percursos honrados de heróis masculinos.

During this study, a focus is placed on the physical transformations that cassava undergoes during convective drying.The product continually changes its size, shape, even its texture and consistency. The more moisture a product loses, the smaller its size.Firstly, the results show that water parameters such as mass or moisture content are reduced according to the drying principle.The dimensions length L, width l and thickness e decrease following a linear trend. The mathematical equations describing them were determined using the Excel office tool. This trend impacts surface and volume parameters, which in turn decrease almost linearly with the water content of the product. Note that the R2 coefficient is not always acceptable, confirming the complexity of the behavior of organic products.

Published: February 2025

The implementation of Basel III regulations has become a crucial factor influencing the financial performance of the banking sector in Bangladesh. The primary objective of this study is to examine the impact of Basel III implementation on the financial performance of the banking industry in Bangladesh. The research utilizes secondary data from 20 commercial banks in Bangladesh, including state-owned, private, and Islamic banks. It offers a diverse and representative sample of Bangladesh’s banking sector, covering the period from 2014 to 2023. This variety ensures a comprehensive understanding of different banking models and their challenges, representing the scenario of the whole industry. A multivariate regression model with fixed effects, determined by the Hausman test, was employed to analyze the relationship between capital adequacy (CRAR, Core Capital Tier-1, Tier-1, and Tier-2 Capital Ratios) and bank-specific factors (size, provisions) on performance indicators (ROA and NPL). The findings reveal that higher capital adequacy, particularly the Tier-1 Capital Ratio, and CRAR, positively influences bank profitability (measured by ROA) and reduces NPLs. Conversely, larger bank size correlates with lower ROA and higher NPLs, and increased provisions also lead to higher NPLs. These results underscore the significance of Basel III in enhancing the financial performance and stability of the banking sector in Bangladesh, suggesting that more substantial capital buffers can improve profitability and reduce risks associated with non-performing loans.
Bifurcation and chaos analysis of the floating raft vibration isolation system with quasi-zero-stiffness isolators
Authors: Fang Ming , Shi Zhengong , Xing Shuo , Zhang Miao , Li Zhipeng
Published: February 2025

This paper presents an investigation into the nonlinear dynamic behaviors of the floating raft isolation system coupled with quasi-zero-stiffness isolators subject to multiple disturbance sources. First, the coupling effects between the excitation source and isolation system are considered. Also, the floating raft isolation model under multiple excitations and its motion equation are deduced, and then the dynamic responses are mainly investigated by using the techniques of time history diagram, spectrum diagram, phase diagram and Poincaré map, and the bifurcation diagram. Finally, the bifurcations of the mechanical isolation system with different parameters are analyzed through numerical methods, especially the effect of center distance and mass ratio. The result predicts that the floating raft shows an alternate phenomenon of periodic motion, quasi-periodic motion, and chaotic motion when the center distance and mass ratio vary. The motion state of the floating raft vibration isolation system is more sensitive to the mass ratio than to the center distance. The horizontal and rotational response of the system becomes very intense in the chaotic state, and the response amplitudes in the horizontal and vertical directions reach the same order of magnitude. Above all, the dynamic characteristics can provide the theoretic supporting for the dynamics, vibration control and its parametric optimization of the floating raft isolation system coupled with quasi-zero-stiffness isolators. This study will lay down the requirements for the engineering design and application of floating raft isolation equipment in large vessel.
Análisis bibliométrico sobre la construcción social de mercados y de la calidad en la contemporaneidad del sector agroalimentario
Authors: Borges de Souza Amanda , Schultz Glauco , Triana Riveros Jorge Luis
Published: February 2025

La discusión sobre los mercados desde una dinámica centrada en el sesgo sociológico se ha fomentado en los últimos años, especialmente desde las décadas de 1970 a 1980. Considerando la relevancia de los estudios que discuten los mercados en la perspectiva de sociología económica en el sector agroalimentario, este artículo mapeó la literatura actual sobre la construcción social de los mercados y la calidad, a través del procedimiento metodológico de revisión bibliométrica. Encontramos que Estados Unidos, Francia y Brasil tienen una influencia considerable en relación con los estudios sobre la construcción social de los mercados. Los investigadores brasileños son pioneros en los estudios relacionados con la construcción social de la calidad en los mercados de alimentos. Se concluye que, en los mercados socialmente construidos, el análisis se centra en los objetos de intercambio influidos por las relaciones sociales, en donde la calidad es una de las formas de coordinación de los procesos socialmente determinados.
Do the Weak Have a Right to Fight the Strong? Moral Absolutes and the Probability of Success
Authors: Buzar Stipe
Published: February 2025

The jus ad bellum requirement of the probability of success can be perceived as an unjust requirement which prohibits the weaker side of a potential or actual military conflict from committing itself to organized violence, even to defend and protect its own survival. This view of the probability of success as an unjust requirement, however, need only be held if: (1) the goal of the weaker state is survival itself. In cases when (1) is true, the requirement should be considered void. On the other hand, if: (2) survival is not considered an overriding factor, then the requirement stands. This paper explores the latter position using the example of the famous Melian Dialogue from Thucydides’ History of the Peloponnesian War, and applies it to the question of Ukraine’s right to war and their government’s possible moral obligation to negotiate in their current defensive war against Russia.

Optimization of bypass dual throat nozzle for thrust vectoring using improved HHO and RBF surrogate model
Authors: RAVINDRANATH Arun
Published: February 2025

Abstract. The optimization of aerospace propulsion systems plays a pivotal role in enhancing performance and efficiency. This paper presents a comprehensive analysis of a 2D bypass dual throat nozzle, with a primary focus on optimizing two critical design parameters: expansion ratio and bypass width, to maximize the mass flow rate and facilitate thrust vectoring capabilities. An improved Harris Hawks Optimization (HHO) algorithm was leveraged in this research to achieve an optimal configuration for the nozzle. Furthermore, the complex relationship between design parameters and mass flow rate is approximated using a Radial Basis Function (RBF) surrogate model, allowing for effective optimization. Through extensive simulations and analyses, the effectiveness of the proposed methodology is demonstrated, showcasing significant improvements in nozzle performance compared to conventional approaches. Furthermore, the optimized configuration obtained through the HHO algorithm is systematically compared with other metaheuristic optimization algorithms, highlighting its superiority in achieving optimal solutions for thrust vectoring applications. This study advances aerospace propulsion technology by providing valuable insights into the optimization of bypass dual throat nozzles, thereby paving the way for enhanced performance and maneuverability in aerospace systems.

Published: February 2025

This study aims to determine the effect of feeding rations with different protein levels. This research was conducted in Nyitdah Village, Kediri District, Tabanan Regency, Bali, which lasted for 12 weeks. The design used was a completely randomized design (CRD) consisting of four treatments and four replicates. Each replicate contained one pig. The treatments were Balinese pigs fed a ration with 14% protein level (P1), Balinese pigs fed a ration with 16% protein level (P2), Balinese pigs fed a ration with 18% protein level (P3), and Balinese pigs fed a ration with 20% protein level (P4). The variables observed were performance, nutrient digestibility, and income over feed cost. The results showed that growing pigs fed different protein levels had no significant effect (P>0,05) on initial and final weights, body weight gain, ration consumption, FCR, and nutrient digestibility. It can be concluded that feeding rations with protein levels of 14% to 20% showed no significant effect on the performance of the pigs and nutrient digestibility, however, rations with 16% protein content produced the highest income over feed cost.
Reporting Quality of AI Intervention in Randomized Controlled Trials in Primary Care: Systematic Review and Meta-Epidemiological Study
Authors: Zhong Jinjia , Zhu Ting , Huang Yafang
Published: February 2025

Background

The surge in artificial intelligence (AI) interventions in primary care trials lacks a study on reporting quality.

Objective

This study aimed to systematically evaluate the reporting quality of both published randomized controlled trials (RCTs) and protocols for RCTs that investigated AI interventions in primary care.

Methods

PubMed, Embase, Cochrane Library, MEDLINE, Web of Science, and CINAHL databases were searched for RCTs and protocols on AI interventions in primary care until November 2024. Eligible studies were published RCTs or full protocols for RCTs exploring AI interventions in primary care. The reporting quality was assessed using CONSORT-AI (Consolidated Standards of Reporting Trials–Artificial Intelligence) and SPIRIT-AI (Standard Protocol Items: Recommendations for Interventional Trials–Artificial Intelligence) checklists, focusing on AI intervention–related items.

Results

A total of 11,711 records were identified. In total, 19 published RCTs and 21 RCT protocols for 35 trials were included. The overall proportion of adequately reported items was 65% (172/266; 95% CI 59%-70%) and 68% (214/315; 95% CI 62%-73%) for RCTs and protocols, respectively. The percentage of RCTs and protocols that reported a specific item ranged from 11% (2/19) to 100% (19/19) and from 10% (2/21) to 100% (21/21), respectively. The reporting of both RCTs and protocols exhibited similar characteristics and trends. They both lack transparency and completeness, which can be summarized in three aspects: without providing adequate information regarding the input data, without mentioning the methods for identifying and analyzing performance errors, and without stating whether and how the AI intervention and its code can be accessed.

Conclusions

The reporting quality could be improved in both RCTs and protocols. This study helps promote the transparent and complete reporting of trials with AI interventions in primary care.

Published: February 2025

Background

The mainstay of colorectal cancer care is surgical resection, which carries a significant risk of complications. Efforts to improve outcomes have recently focused on intensive multimodal prehabilitation programs to better prepare patients for surgery, which make the perioperative process even more complex and demanding for patients. Digital applications (eCoaches) seem promising tools to guide patients during their care journey. We developed a comprehensive eCoach to support, guide, and monitor patients undergoing elective colorectal surgery through the perioperative phase of the care pathway.

Objective

The primary aim of this study was to determine its feasibility, in terms of recruitment rate, retention rate, and compliance. Also, usability and patient experience were examined.

Methods

A single-center cohort study was conducted from April to September 2023 in a tertiary teaching hospital in the Netherlands. All elective colorectal surgery patients were offered an eCoach that provided preoperative coaching of the prehabilitation protocol, guidance by giving timely information, and remote monitoring of postoperative recovery and complications. Recruitment and retention rate, as well as compliance for each part of the care pathway, were determined. Secondary, patient-reported usability measured by the Usefulness, Satisfaction, and Ease of Use questionnaire and patient experiences were reported.

Results

The recruitment rate for the eCoach was 74% (49/66). Main reasons for exclusion were digital illiteracy (n=10), not owning a smartphone (n=3), and the expected burden of use being too high (n=2). The retention rate was 80% (37/46). Median preoperative compliance with required actions in the app was 92% (IQR 87-95), and postoperative compliance was 100% (IQR 100-100). Patient-reported usability was good and patient experiences were mostly positive, although several suggestions for improvement were reported.

Conclusions

Our results demonstrate the feasibility of a comprehensive eCoach for guiding and monitoring patients undergoing colorectal surgery encompassing the entire perioperative pathway, including prehabilitation and postdischarge monitoring. Compliance was excellent for all phases of the care pathway and recruitment and retention rates were comparable with rates reported in the literature. The study findings provide valuable insights for the further development of the eCoach and highlight the potential of digital health applications in perioperative support.

BACKGROUND

Contactless monitoring of vital signs, especially the breathing of children, in the hospital is performed on a priority basis because their organs and immune system are immature. Therefore, continuous monitoring of their vital signs with a sensor that is directly attached to their body is not possible, as it irritates the sensitive newborn skin and causes discomfort. A contactless frequency-modulated continuous-wave (FMCW) radar-based device can wirelessly monitor the breathing rate and pattern of a child in the hospital or at home. Signal-processing capability can be added to this device to process breathing data and analyze the apnea condition arising due to irregular breathing patterns.

OBJECTIVE

This study will develop a contactless FMCW radar-based system to accurately monitor the breathing rate and pattern of neonates and infants in hospitals and at home in order to provide a noninvasive, nonintrusive and contactless alternative to conventional sensor-based methods and address a critical need in neonatal care, potentially improving health outcomes for vulnerable infants.

METHODS

The radar transmits a signal toward the body, and the time taken by the signal received to travel from the body to the receiving antenna is analyzed. This time is proportional to the distance between the radar and the body, and the breathing pattern is recognized as a slight, periodic variation in this distance. We will use this concept with multiple antenna systems to monitor the breathing of neonates with improved sensitivity. The radar-based device will be installed, in addition to conventional breathing monitors, in the neonatal intensive care unit. The signals received at the radar and the respiration signals from conventional monitors will be recorded in a database. Signal-processing techniques will be applied to extract breathing signals from the signals received at the radar.

RESULTS

This study was funded in January 2023 by the Science and Engineering Research Board (SERB) of India. The device was designed by May 2024, and a working proof-of concept was verified in the Indian Institute of Technology (IIT) Ropar laboratory. Implementation of the proposed method for initial study began in December 2024. Results are expected to be published in the first quarter of 2025.

CONCLUSIONS

The contactless FMCW radar-based system will provide reliable estimation of the breathing rate and pattern, which is close to the conventional reference device values most of the time. Our device will also provide a seamless breathing-monitoring system to be used both in hospitals and at home for newborns and premature babies until they are fully healthy and fit.

What is Most Bothersome About Section 33: Or What Hasn’t Yet Been Said
Authors: Diab Robert
Published: February 2025

The political revival of the notwithstanding clause in Canada’s Charter has led to an explosion of literature on section 33, yet few of the arguments about the legitimacy of the override are new. All of the basic positions in the debate were mapped out in the 1980s, resulting in an impasse over the merits of section 33 that we have not moved beyond. This commentary seeks to sidestep this debate by offering a new perspective on an old argument: the override seems out of place in the Charter because without it, the document embodies Ronald Dworkin’s theory of rights as trumps. What is most bothersome to opponents of section 33 is that its inclusion prevents the Charter from reflecting this Kantian, humanist conception of rights. By subordinating rights to the possible whim of the majority, the override reflects a populist or at best utilitarian conception. To read the Charter in this light is to see it not primarily as a legal instrument but as a moral statement.
Global View on Statistical Models of Sea Surface Elevations
Authors: Zapevalov Aleksander
Published: February 2025

The verification of statistical models of sea surface elevations based on the decomposition of the wave profile into degrees of a small parameter (wave steepness) and in terms of multidimensional integrals of wave spectra was carried out. For verification, wave measurement data were used to calculate the skewness and excess kurtosis of surface elevations, as well as the distribution of crests and troughs. Two factors are identified that limit the use of estimates of skewness Aη and excess kurtosis Eη obtained from existing models. First, the model estimates Aη and Eη are always non-negative, although the measurement data show that the lower limit of the ranges in which the skewness and excess kurtosis change is in the region of negative values. Secondly, almost all existing models are one-parameter models, using wave steepness and wave age as predictors; whereas the measured data indicate that there is no clear relationship. The values of Aη and Eη vary greatly for fixed values of the predictors. Existing statistical models can only describe average changes Aη and Eη. This limits the scope of their application. The analysis of the probability density functions of the troughs FT h and crests FCr showed that the function calculated for Aη < 0 in the region above the distribution mode exceeds the values corresponding to the Rayleigh distribution, and the relationship FT h ≈ FCr holds. The second order nonlinear model is inconsistent with this result. Negative skewness values are observed much less frequently than positive ones, so the functions FT h and FCr calculated for the whole ensemble of situations are consistent with the second-order nonlinear model.

This study aimed to investigate differences in postural stability between adolescents with scoliosis and typically developed peers.Researchers conducted a cross-sectional study of 75 participants (53 male, 22 female) divided into two groups. The first group consisted of 35 adolescents with scoliosis (aged 17.15 ± 1.31 years; BMI 22.3 ± 2.6), while the second group consisted of 40 typically developed peers (aged 16.74 ± 1.3 years; BMI 22.6 ±2.5 females). The CONTEMPLAS 3D Kinematic System measured the level of scoliosis, while researchers used the Force Plate and double leg standing test to measure postural stability parameters.Adolescents with scoliosis demonstrated significantly lower postural stability in the Center of pressure (p<0.001), Length function of surface (p<0.001) than typically developed peers. Furthermore, adolescents with scoliosis had higher Anterior-Posterior displacement of COP (p<0.001) and Medio-Lateral displacement of COP (p<0.001) compared to typically developed peers, indicating lower levels of postural stability.This study suggests that adolescents with scoliosis have lower postural control and balance than typically developed peers. The findings highlight the importance of identifying and addressing these issues to optimize the health and well-being of adolescents with scoliosis.
