The problem most often faced by CV TJA is that the price from the RAB (Cost Budget Plan) calculation is not in accordance with market prices, so it is necessary to predict the price of building materials to help the company prepare the RAB. The aim of this research is to examine predictions of material prices measured using the ARIMA method. The data analysis method in this study used the MA parameter (1) with the ARIMA model (0,1,1) for dynamix cement material, the MA parameter (1) ARIMA model (0,2,1) for cast sand, the MA parameter (1 ) ARIMA model (0,3,1) for threaded iron 13 and AR parameter (2) ARIMA model (2,1,0) for usuk wood material. By using 3 error testing methods, namely Mean Absolute Percentage Error (MAPE), Mean Absolute Deviation (MAD) and Mean Squared Deviation (MSD). The results of this analysis show the lowest accuracy value, namely for dynamic cement material with a MAPE value of 5%, a MAD value of 1.986 and an MSD value is 63.584.667. The results of error tests using MAPE, MAD and MSD can be concluded that the ARIMA method is very accurate because the MAPE value is less than 10%.

Published: July 2024

Low-mass ratio systems (LMR) are a very interesting class of contact eclipsing binaries challenging the theoretical models of stability. These systems are also considered possible progenitors of the rare low-mass optical transients called red novae. In this study, we present the identification of 7 new totally eclipsing LMR systems from Catalina Sky Surveys (CSS) and 77 LMR candidates from the All Sky Automated Survey. Using the available CSS light curves and new multiband observations for CSS_J210228.3-031048 and CSS_J231513.3+345335 with the 2.3 m Aristarchos telescope at Helmos Observatory, we estimate their physical and absolute parameters and investigate their stability and their progenitors. The light curves are analyzed by performing a two-dimensional scan on the mass–ratio inclination plane with Phoebe-0.31 scripter, while the errors are estimated using Monte Carlo simulations and heuristic scanning of the parameter space. Our analysis revealed that all 9 CSS systems have extreme mass ratios from 0.09 to 0.16. Our statistical analysis of well-studied LMR contact binaries shows that LMR systems tend to have warmer and more massive primaries. The investigation of the progenitors of both low and higher-mass-ratio systems reveals a trend for the former to originate from higher-mass ancestors. Finally, we investigate the stability condition by calculating the ratio of spin angular momentum to orbital angular momentum and other stability indicators in the context of the reliability of the solutions.
Photometric Completeness Modelled with Neural Networks
Authors: Harris William E. , Speagle 沈 Joshua S. 佳士
Published: July 2024

In almost any study involving optical/near-infrared photometry, understanding the completeness of detection and recovery is an essential part of the work. The recovery fraction is, in general, a function of several variables including magnitude, color, background sky noise, and crowding. We explore how completeness can be modeled, with the use of artificial-star tests, in a way that includes all of these parameters simultaneously within a neural network (NN) framework. The method is able to manage common issues including asymmetric completeness functions and the bilinear dependence of the detection limit on color index. We test the method with two sample Hubble Space Telescope data sets: the first involves photometry of the star cluster population around the giant Perseus galaxy NGC 1275, and the second involves the halo-star population in the nearby elliptical galaxy NGC 3377. The NN-based method achieves a classification accuracy of > 94% and produces results entirely consistent with more traditional techniques for determining completeness. Additional advantages of the method are that none of the issues arising from the binning of the data are present and that a recovery probability can be assigned to every individual star in real photometry. Our data, models, and code (called COINTOSS) can be found online on Zenodo at the following link: https://doi.org/10.5281/zenodo.8306488.
Sensitivity of Polarization to Grain Shape. II. Aggregates
Authors: Draine B. T.
Published: July 2024

A previous study (Paper I) investigated the polarization properties of a variety of simple convex grain shapes, some of which were found to be consistent with the observed polarization properties of interstellar dust from far-ultraviolet to far-infrared. Here, we study the optical properties of 45 nonconvex shapes, all aggregates of N equal-sized spheres. We consider N = 2, N = 3, and N = 256 random aggregates obtained from three different aggregation schemes. We also consider “trimmed” N = 256 aggregates obtained by systematically trimming initially random aggregates to increase either flattening or elongation. The “macroporosities” of the studied aggregates range from

P

macro

=
0.18

(for the N = 2 bisphere) to

P

macro

≈
0.85

(for the N = 256 “BA” aggregates). The only aggregates consistent with observations of starlight polarization and polarized thermal emission are shapes that have been trimmed to increase their asymmetry. If interstellar grains are high-porosity aggregates, there must be processes causing extreme elongation or flattening; if not, interstellar grains must be dominated by fairly compact structures, with at most moderate porosities. The ratio of polarization in the 10 μm silicate feature to starlight polarization in the optical is shown to be insensitive to porosity and shape. X-ray scattering may be the best tool to determine the porosity of interstellar grains. We propose that modest porosities of interstellar grains could be the result of “photolytic densification.” High polarization fractions observed in some Class 0 cores require processes to reduce porosities and/or increase asymmetries of aggregates in dense regions.
Planetesimal Drift in Eccentric Disks: Possible Outward Migration
Authors: Silsbee Kedron
Published: July 2024

Radial drift of solid particles in the protoplanetary disk is often invoked as a threat to planet formation, as it removes solid material from the disk before it can be assembled into planets. However, it may also concentrate solids at particular locations in the disk, thus accelerating the coagulation process. Planetesimals are thought to drift much faster in an eccentric disk, due to their higher velocities with respect to the gas, but their drift rate has only been calculated using approximate means. In this work, we show that in some cases previous estimates of the drift rate, based on a modification of the results for an axisymmetric disk, are highly inaccurate. In particular, we find that under some easily realized circumstances, planetesimals may drift outwards, rather than inwards. This results in the existence of radii in the disk that act as stable attractors of planetesimals. We show that this can lead to a local enhancement of more than an order of magnitude in the surface density of planetesimals, even when a wide dispersion of planetesimal size is considered.

We seek to understand the composition and variability of fast solar wind (FSW) and slow Alfvénic solar wind emerging from coronal holes (CHs). We leverage an opportune conjunction between Solar Orbiter and Parker Solar Probe (PSP) during PSP Encounter 11 to include compositional diagnostics from the Solar Orbiter Heavy Ion Sensor as these variations provide crucial insights into the origin and nature of the solar wind. We use potential field source surface and magnetohydrodynamic models to connect the observed plasma at PSP and Solar Orbiter to its origin footpoint in the photosphere and compare these results with the in situ measurements. A very clear signature of a heliospheric current sheet crossing as evidenced by enhancements in low first ionization potential (FIP) elements, ion charge state ratios, proton density, low Alfvénicity, and polarity estimates validates the combination of modeling, data, and mapping. We identify two FSW streams emerging from small equatorial CHs with low ion charge state ratios, low FIP bias, high Alfvénicity, and low footpoint brightness, yet anomalously low alpha particle abundance for both streams. We identify high-Alfvénicity slow solar wind emerging from the overexpanded boundary of a CH having intermediate alpha abundance, high Alfvénicity, and dips in ion charge state ratios corresponding to CH boundaries. Through this comprehensive analysis, we highlight the power of multi-instrument conjunction studies in assessing the sources of the solar wind.
Modeling of Granulation in Red Supergiants in the Magellanic Clouds with the Gaussian Process Regressions
Authors: Zhang 张 Zehao 泽浩 , Ren 任 Yi 逸 , Jiang 姜 Biwei 碧沩 , Soszyński Igor , Jayasinghe Tharindu
Published: July 2024

The granulation of red supergiants (RSGs) in the Magellanic Clouds is systematically investigated by combining the latest RSG samples and light curves from the Optical Gravitational Lensing Experiment and the All-Sky Automated Survey for Supernovae. The present RSG samples are first examined for foreground stars and possible misidentified sources, and the light curves are sequentially checked to remove the outliers by white noise and photometric quality. The Gaussian process (GP) regression is used to model the granulation, and the Markov Chain Monte Carlo is applied to derive the granulation amplitude σ and the period of the undamped oscillator ρ, as well as the damping timescale τ. The dimensionless quality factor Q is then calculated through Q = π
τ/ρ. RSGs around

are considered to have significant granulation signals and are used for further analysis. Combining granulation parameters with stellar parameters, robust scaling relations for the timescale ρ are established, while the scaling relations for amplitude σ are represented by a piecewise function, possibly related to the tendency of amplitudes in faint RSGs to converge toward a certain value. Comparing results between the Small Magellanic Cloud and the Large Magellanic Cloud confirms that amplitudes and timescales become larger with metallicity. In examining the scaling relations between the two galaxies, it is found that ρ is nearly independent of metallicity, whereas σ is more significantly affected by metallicity. The GP method is compared with the periodogram fitting of the granulations, and the advantages of either are discussed.
Discriminating between Babcock–Leighton-type Solar Dynamo Models by Torsional Oscillations
Authors: Zhong Congyi , Jiang Jie , Zhang Zebin
Published: July 2024

The details of the dynamo process in the Sun are an important aspect of research in solar-terrestrial physics and astrophysics. The surface part of the dynamo can be constrained by direct observations, but the subsurface part lacks direct observational constraints. The torsional oscillations, a small periodic variation of the Sun's rotation with the solar cycle, are thought to result from the Lorentz force of the cyclic magnetic field generated by the dynamo. In this study, we aim to discriminate between three Babcock–Leighton dynamo models by comparing the zonal acceleration of the three models with the observed one. The property that the poleward and equatorward branches of the torsional oscillations originate from about ±55° latitudes with their own migration time periods serves as an effective discriminator that could constrain the configuration of the magnetic field in the convection zone. The toroidal field, comprising poleward and equatorward branches separated at about ±55° latitudes, can generate the two branches of the torsional oscillations. The alternating acceleration and deceleration bands in time are the other property of the torsional oscillations that discriminates between the dynamo models. To reproduce this property, the phase difference between the radial (B

r
) and toroidal (B

ϕ
) components of the magnetic field near the surface should be about π/2.
Supernova Explosions of the Lowest-mass Massive Star Progenitors
Authors: Wang Tianshu , Burrows Adam
Published: July 2024

We here focus on the behavior of supernovae that technically explode in 1D (spherical symmetry). When simulated in 3D, however, the outcomes of representative progenitors of this class are quite different in almost all relevant quantities. In 3D, the explosion energies can be 2 to 10 times higher, and there are correspondingly large differences in the 56Ni yields. These differences between the 3D and 1D simulations reflect in part the relative delay to explosion of the latter and in the former the presence of protoneutron star convection that boosts the driving neutrino luminosities by as much as ∼50% at later times. In addition, we find that the ejecta in 3D models are more neutron-rich, resulting in significant weak r-process and 48Ca yields. Furthermore, we find that in 3D the core is an interesting, though subdominant, source of acoustic power. In summary, we find that though a model might be found theoretically to explode in 1D, one must perform supernova simulations in 3D to capture most of the associated observables. The differences between 1D and 3D models are just too large to ignore.
La coercition dans l’histoire du travail en Chine au début de l’époque moderne. Catégories et idées préconçues
Authors: Chevaleyre Claude , Goudarzi Tiam
Published: July 2024

Cet essai critique invite les historiens de la Chine à réinvestir le champ de l’histoire de la coercition au début de l’époque moderne, de manière à réévaluer l’importance du travail contraint, mais aussi repenser les mondes sociaux des dynasties Ming et Qing. Si les historiens de la Chine ont toujours accordé une grande attention au travail et aux relations de travail, la coercition semble avoir quelque peu disparu des travaux récents. Ce manque relatif d’attention résulte principalement de l’abandon de l’accent, parfois excessif, mis sur les masses laborieuses en tant que victimes de l’exploitation « féodale ». Mais il est également la conséquence de l’utilisation d’une terminologie vague, de traductions hâtives et d’idées préconçues qui n’ont jamais été remises en question. Un consensus semble notamment s’être dégagé sur le fait que la société chinoise, depuis le xviii e  siècle, aurait été dominée par un marché du travail libre. Nous soutenons que cette hypothèse découle de transpositions des cadres analytiques de l’Occident moderne non soumises à l’examen critique, et d’une représentation erronée des politiques des Qing visant les « sujets dégradés » ( jianmin ) et les « travailleurs à gages » ( gugong ).
Recréer une société en réseau sur Internet : résistance des coursiers chinois et régulation du capitalisme de plateforme
Authors: Froissart Chloé , Huang Ke , Goudarzi Tiam
Published: July 2024

En s’appuyant sur des études de cas, cet article révèle les particularités du régime de travail des plateformes chinoises de livraison de nourriture, ainsi que les formes de résistance des coursiers. Si l’asymétrie de pouvoir entre plateformes et coursiers crée une nouvelle forme d’exploitation capitaliste qui suscite le mécontentement, le système de contrôle d’externalisation multiple adopté par les plateformes a atomisé à l’extrême les livreurs. Les réseaux sociaux demeurent, malgré un renforcement du contrôle social et de la censure en ligne, un espace d’innovations tactiques permettant aux coursiers de surmonter cette atomisation et de défendre leurs droits. Cet article étudie la manière dont ils utilisent Internet pour agir ensemble, recréer un collectif et faire appel au public des consommateurs dans la construction d’une solidarité plus large, tentant ainsi de renverser l’asymétrie de pouvoir. Même si les contestations de coursiers ne parviennent pas à entraîner de modifications législatives, nous soutenons qu’elles peuvent néanmoins modifier les règles des entreprises.
Teaching E. E. Cummings’ No Thanks
Authors: Alfandary Isabelle
Published: July 2024

The reading of a modernist book of poems such as No Thanks (1935) by E. E. Cummings is affected and impacted by what may be regarded as minor changes in the book presentation, such as the presence or absence of an introduction to the collection, as well as typographical modifications. In fact, editorial options often prove decisive in the reading experience. This article seeks to examine the material conditions that determine the reception of E. E. Cummings’ poetry in the classroom and beyond, inasmuch as it is based on visual and grammatical games.
Killers of the Flower Moon: een pleister op Amerika’s erfzonde
Authors: Capiau Brecht
Published: July 2024

In 1974 vatte regisseur Martin Scorsese al het plan op om een film te maken over de oorspronkelijke Amerikanen. Een bezoek aan het Pine Ridge reservaat bij de Oglala Lakota Sioux in Zuid-Dakota hadden zijn ogen geopend voor de discriminatie, het racisme en de ellendige levensomstandigheden waar de ‘indianen’ zich in bevonden. Het boek, waarop de cineast zich zou baseren, was net zoals Killers of the Flower Moon een non-fictie werk: Bury My Heart at Wounded Knee: An Indian History of the American West van Dee Brown. Het behandelt de Amerikaanse, westwaartse politiek in de periode 1830-1890 en werpt een kritische blik op het effect ervan op de inheemse Amerikanen. Ondanks interesse van acteur Marlon Brando viel het project uiteindelijk in het water. Retrospectief gezien was dit wellicht de juiste samenloop van omstandigheden. Scorsese was op dat moment veel te veel bezig met zijn eigen schuld en boete (Mean Streets, 1973) en de verwerking van het door iedereen gedeelde Vietnam trauma (Taxi Diver, 1976) om een engagement aan te gaan voor een dergelijk project. Vijftig jaar na datum laat Killers of the Flower Moon, een verfilming van het gelijknamige boek van David Grann, zich bekijken als een meesterwerk van een gelouterde grootmeester van de cinema op het toppunt van zijn kunnen.
De Processen van Istanboel

Published: July 2024

In dit artikel worden de processen behandeld die gevoerd moesten worden tegen de verantwoordelijken voor de systematische uitroeiing van de Armeniërs tijdens de Eerste Wereldoorlog. Het toont aan dat het – vanaf de wapenstilstand van Moudros tot eind 1920 – de wil van opeenvolgende Ottomaanse regeringen was om hun eigen processen te organiseren, zodat ze niet moesten samenwerken met een tribunaal van de overwinnaars, waaraan ze officiële documenten zouden moeten overhandigen en Ottomaanse beschuldigden zouden moeten uitleveren. Finaal droegen de processen van Istanboel onweerlegbare bewijzen aan van een misdaad die na 1948 gekwalificeerd zou worden als de genocide op de Armeniërs.
How Climate Action Plans are modified by the energy crisis? A focus on residential heating in Bristol
Authors: Hatem Nicolas
Published: July 2024

The recent surge in European energy prices could substantially reduce the social cost of Climate Action Plans. This paper conducts an ex-ante Cost-Benefit Analysis of mitigation policies in residential heating and studies the extent to which rising energy prices modifies their cost-effectiveness. I use the city of Bristol (UK) as a case study and assess two options: (1) investing in district heating networks in central districts or (2) subsidizing energy efficiency retrofits for least efficient dwellings. Implementing either of the two policy options under high energy prices trends increase economic benefits to households by around £ 1 per pound invested, in present value, relative to a scenario with baseline energy prices trends. Besides, district heating networks become more cost-effective at mitigating carbon emissions than energy efficiency retrofits.JEL classification: D61, Q41, Q48, Q58

Empathy building through Virtual Reality filmmaking in social innovation: Decreasing tensions between socially opposed citizens
Authors: Sleeswijk Visser Froukje , Van Erp Jeroen
Published: July 2024

In our densely-populated cities, living together in harmony between different groups of people becomes an increasingly difficult art, and one in which design can provide positive contributions. This paper describes a design project which aimed to decrease tensions between youth and residents in a city neighbourhood through an empathy-building process. Individuals from both groups were guided through the process of stepping into each others’ worlds through Virtual Reality and developing solutions together to address points of tension. Their individual transformative processes were researched through a content analysis procedure in order to make the implicit outcomes of such design processes explicit. Throughout this process new dynamics and connections emerged, revealing grounds for structurally decreasing tensions and promoting participatory approaches for social innovation. This paper describes the project and presents our learnings regarding (1) the transformative impact on the involved individuals from the neighbourhood and (2) reflections on the contributing roles of the designers in social innovation projects.
Designing Empathetic Service Experiences Using Storytelling Approach: A Case Study
Authors: Sagar Priyank , Mahamuni Ravi , Agrawal Vasundhara , Darak Shrinivas , Jori Vijaya , Athavale Sandeep
Published: July 2024

Storytelling is a well-known technique to emphasize emotions. This paper explores the integration of storytelling techniques into service design to cultivate empathetic service experiences. Emphasizing the significance of emotional connection in social service contexts, we designed services for Adolescents Living with HIV (ALHIV) in India. Due to a lack of awareness and social stigma, ALHIV are unable to make timely and responsible life decisions around intimacy and HIV status disclosure. We designed services that disseminate essential information and enable ALHIV to make informed life decisions. The solution is an interactive story media where users make decisions around in-design encounters that parallel with possible real-life encounters. As a result, they get to explore multiple possibilities in a safe space, leading to improved real-life decision-making. This paper demonstrates the replicable framework of orchestration of human and technology touchpoints through multiple dynamic and choice-based scenarios.
The study examines the synergy between service design and narrative frameworks. Through a detailed case study, the research underscores the pivotal role of storytelling in fostering genuine user engagement by infusing empathy-driven narratives into service encounters. Overall, this research contributes a novel perspective on designing empathetic services, demonstrating the role of storytelling in crafting meaningful service experiences.
‘SOSpesa’: Service Design Leveraging Neighborhood Solidarity Networks to Tackle Food Poverty, Food Surplus, and Sustainability of Local Commerce
Authors: Meroni Anna , Fassi Davide
Published: July 2024

This paper illustrates a project to redesign a charitable initiative against food poverty into an innovative solution called "SOSpesa", implemented in a neighborhood of the city of Milan named NoLo - North of Loreto. The paper outlines approach, methodology and strategy to move from an activist initiative to a service with more than charitable purposes and outlines the new service configuration in its opportunities and limitations as emerged from the pilot project. It focuses on strategies to harness a network of neighborhood actors to achieve a goal of solidarity, combating food waste and supporting local shops. Based on the assumption that the local context is a strength of the service, the project activated a wide range of actors, from volunteers to third sector organizations and businesses, under the coordination of a team of researchers, to experiment with different service configurations in search of overall sustainability. Finally, the paper discusses design strategies for scaling up grassroots social innovation through replicability, not to distort its spirit and bottom-up engagement.
The Role of Service Design and Co-design in the Lifecycle of Online Communities: Cases from the Chinese Service Design Community
Authors: Zhang Chenfan , Selloni Daniela , Auricchio Valentina
Published: July 2024

COVID-19 and technological advances have made online communication more common, which has increased the number of online communities. However, online communities tend to rise and fall rapidly, and maintaining active participants is vital to online community survival and development. While online communities connect many diverse participants, they also add to the complexity of the network and challenge participants to collaborate and participate. Despite the widespread use of service design and co-design for collaborating and participating in offline communities, there have been few studies examining their application and contribution online. This study uses participatory action research as a methodology. It takes China's online community, Chinese Service Design Community (CSDC), as a research object, analyses its development process from 2019 to 2022, and combines the online community life cycle proposed by Iriberri and Leroy as an analytical model to illustrate how service design and co-design activities can contribute to the community's transition from "inception" to "maturity" (Iriberri & Leroy, 2009). In addition, it also explores how service design and co-design can help to produce the ‘legacy’ for the long-term development of online communities by reflecting on the influences of the 'heroes' of online communities.
Why do Service Designers Struggle to Address Power Dynamics?
Authors: Hay Audun Formo , Vink Josina , Thøgersen Dagfinn Mørkrid , Suoheimo Mari
Published: July 2024

To support transformation in service systems, scholars argue for greater attention to power dynamics in service design (SD). While current literature stresses the need for individual service designers to be reflexive about power, it neglects the context within which these designers predominantly work. We argue that such an individual focus overlooks key contextual factors that hinder service designers from addressing power dynamics. This narrowed view of the challenge unintentionally positions service designers as scapegoats, while their inability to address power dynamics effectively persists. In response, we draw on ecological theories in psychology, which offer insights into how individuals’ behaviors are interconnected with factors in their context. We introduce a framework for understanding these interconnections, detailing how we used it to identify and analyze domains of contextual factors that inhibit service designers to address power dynamics in practice. By proposing a systemic framework, identifying related contextual factors, and evaluating applicability with service designers, this study lays the groundwork for structural shifts to address power dynamics in service design more effectively.
Designing for Co-Production in a Territorial Lab for Mental Health
Authors: De Luca Federico , Sangiorgi Daniela
Published: July 2024

This article explores the co-production of mental health services involving informal actors, patients, and healthcare providers, specifically focusing on the potential of territorial laboratories as experimental spaces for co-producing recovery-oriented services. The research centers on the CoLab Torre Cimabue in the city of Brescia (Italy), where the co-production of mental health and well-being services occurs at the community level, engaging users, family members, local actors, and service providers. Through a thematic analysis of interviews on the experiences within CoLab Torre Cimabue, seven main dimensions emerged, shedding light on the potential role of territorial labs in supporting the co-production of mental healthcare with informal resources. These dimensions encompass informal settings and resources, real-life and recovery-oriented experimentations, tangible and welcoming space, horizontal and equitable relationships, exchange of information and service continuity, omnichannel communication and promotion, and urban regeneration and participation. While the co-design process successfully nurtured a collaborative approach and culture among participants, certain factors have proven indispensable. From these dimensions, the research elaborates on seven pivotal factors—Time, Value, Participation, Co-design, Scale, Space, and Attitude—critical for the co-production of mental healthcare with the active engagement of informal resources, encompassing both service design and service delivery phases.

Background: Successful liberation from mechanical ventilation is one of the most crucial processes in critical care, because it is the first step through which a respiratory failure patient begins to transition out of the intensive care unit, and return to normal life. Therefore, when devising appropriate strategies for removing mechanical ventilation, it is essential to consider scientific and systematic approaches, as well as the individual experiences of healthcare professionals. Recently, numerous studies have investigated methods and tools to identify when mechanically ventilated patients are ready to breathe on their own. The Korean Society of Critical Care Medicine therefore provides these recommendations to clinicians for liberation from the ventilator.Methods: Meta-analyses and comprehensive syntheses were used to thoroughly review, compile, and summarize the complete body of relevant evidence. All studies were meticulously assessed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) method, and the outcomes were presented succinctly as evidence profiles. These evidence syntheses were discussed by a multidisciplinary committee of experts in mechanical ventilation, who then developed and approved the recommendations.Results: Recommendations for nine questions on ventilator liberation about Population, Intervention, Comparator, and Outcome (PICO) are presented in this document. This guideline presents seven conditional recommendations, one expert consensus recommendation, and one conditional deferred recommendation.Conclusion: We developed these clinical guidelines for mechanical ventilation liberation to provide meaningful recommendations. These guidelines reflect the best treatment for patients seeking liberation from mechanical ventilation.

Background: This study aimed to investigate the risk factors for chloral hydrate sedation failure and complications in a tertiary children’s hospital in South Korea.Methods: A retrospective analysis of pediatric procedural sedation with chloral hydrate between January 1, 2021, and March 30, 2022, was performed. The collected data included patient characteristics, sedation history, and procedure. Multivariable regression analysis was performed to identify the risk factors for procedural sedation failure and complications.Results: A total of 6,691 procedural sedation were included in the analysis; sedation failure following chloral hydrate (50 mg/kg) occurred in 1,457 patients (21.8%) and was associated with a higher rate of overall complications compared to those with successful sedation (17.5% [225/1457] vs. 6.2% [322/5234]; P < 0.001, odds ratio: 3.236). In the multivariable regression analysis, the following factors were associated with increased risk of sedation failure: general ward or intensive care unit inpatient (compared with outpatient); congenital syndrome; oxygen dependency; history of sedation failure or complications with chloral hydrate; procedure more than 60 min; and magnetic resonance imaging, radiotherapy, or procedures with painful or intense stimuli (all P values < 0.05). Factors contributing to the complications included general ward inpatient, congenital syndromes, congenital heart disease, preterm birth, oxygen dependency, history of complications with chloral hydrate, and current sedation failure with chloral hydrate (all P values < 0.05).Conclusions: To achieve successful sedation with chloral hydrate, the patient’s sedation history, risk factors, and the type and duration of the procedure should be considered.

This research assessed the efficiency of chemically modified tannins as coagulants for water treatment. Tannins from Anacardium occidentale (cashew tree) and Mimosa caesalpiniifolia (‘sabiá’) barks and seedless fruits of Anadenanthera colubrina (‘angico’) and Pityrocarpa moniliformis (‘angico de bezerro’) were evaluated after cationization to remove turbidity from water. After extraction, the total solids content (TSC), Stiasny index (SI), and total condensed tannins content (TCC) of the tannins extracts were determined. Extracted tannins were converted into powders and cationized. Then, the cationized tannins' effectiveness on water turbidity removal, sedimentation time, and effect on pH were assessed. Three concentrations of each type of tannin were used to evaluate flocculant efficiency: 50, 100, and 150 mg L-1. Although the P. moniliformis extract had a higher TSC value (56.06%), it presented the lowest SI (0.42%) and TTC (0.23%) values. M. caesalpiniifolia had the lowest TSC (9.18%) and the highest SI (91.27%), while Ac occidentale stood out with the highest TCC (19.83%). All species have shown potential for tannin production and efficiently removed turbidity at all concentrations. However, only A. occidentale, at a concentration of 100 mg L-1, presented a nephelometric turbidity unit of 2.4, reaching the potability standards required by international specifications and, therefore, being indicated for water treatment.

Aedes aegypti–borne viruses (i.e., dengue, chikungunya, and Zika) have become endemic to India, posing a severe threat to public health. Vector control remains the mainstay of disease management due to nonavailability of licensed vaccines/therapeutics. Conventional morpho-taxonomical methods cannot differentiate between closely related sibling species or species complexes, and hence we evaluated two molecular markers, mitochondrial cytochrome c oxidase subunit 1 (Cox1) and nuclear DNA internal transcribed spacer 2 (-2) gene sequences, to characterize seven populations of Ae. aegypti and four medically important mosquito species (Aedes albopictus, Anopheles stephensi, Culex tritaeniorhyncus, and Culex murrelli). DNA extracted from the 11 mosquito populations (two mosquitoes per population) was polymerase chain reaction amplified, sequenced, and analyzed. Molecular characterization was found to be congruent with morphological identification, suggesting no variants or cryptic species exist in Ae. aegypti and the other mosquitoes studied. Phylogenetic analysis with sequences obtained with Cox1 gene of Ae. aegypti and other Aedes and non-Aedes mosquito species showed clustering of sequences from different species representing different clades, distinctly separating one taxon from the other, whereas ITS-2 sequences of Aedes aegypti from across the world clustered tightly. Nucleotide divergence values revealed a low percentage of intraspecies variation and a higher percentage of interspecies variation. The present study authenticates the applicability of Cox1 and ITS-2 in the precise identification of Ae. aegypti mosquitoes against cryptic or sibling species. Cox1 appeared to be a more reliable marker because it showed distinct clustering of mosquito species, and some sequence variations to represent genetic diversity.

This study explored the experiences of healthcare providers (HCPs) and frontline workers who were involved in an Ebola vaccine trial in the Democratic Republic of the Congo. The researchers interviewed a total of 99 participants (HCPs and frontline workers) living and working in the Boende health district during the period of the study, from February to March 2022. These individuals included a mix of trial participants and non-trial participants (staff of the trial, local health authorities, and head nurses of health centers). In-depth individual interviews, as well as focus group discussions (FGDs), were used to understand interviewees’ experiences and perceptions. The data were analyzed to identify the main themes. The findings unveiled a multitude of positive experiences among interviewees/FGD participants. The commitment of the trial investigators to improve the study site and to equip the volunteers with necessary skills and knowledge greatly contributed to a positive trial experience. However, some interviewees felt that the reimbursement for time and travel expenses during their trial visits was insufficient in comparison with their expectations. Additionally, there were expressions of worry about the frequency of blood draws during scheduled trial visits. Our findings emphasize the critical importance of addressing and continuously considering the perspectives and concerns of trial participants before designing and implementing vaccine trials. By actively incorporating their inputs, researchers can mitigate concerns and tailor communication strategies, potentially enhancing the overall success and impact of the vaccine trial.
