Published: October 2022

Face à la diminution des ressources et afin de réduire l’impact carbone du secteur de la construction, il est important d’envisager la fin de vie des bâtiments. Il faut considérer les constructions et leur structure comme des éléments pouvant être démontés ou désassemblés pour être recyclés ou réutilisés. Cette recherche s’intéresse aux assemblages non-séquentiels, permettant une réversibilité pour répondre à ces enjeux. Pour démontrer l’intérêt de ces assemblages, un prototype de Nexorade échelle 1 a été construit et illustre l’article. La première partie définit l’assemblage non-séquentiel et ses cinématiques possibles. La recherche du pavage et de la géométrie sont évoquées dans la seconde partie. L’article continue sur la génération de la nexorade et son analyse mécanique mettant en évidence l'intérêt d’incliner les poutres de la nexorade, pour réduire la flèche de 35%. La séquence d’assemblage est développée dans la partie 5. Enfin, la construction du pavillon est détaillée, permettant le passage d’un modèle numérique à la fabrication du prototype. Pour conclure cet article, les auteurs discutent des résultats obtenus sur les assemblages non-séquentiels et sur l’inclinaison des poutres. Des extensions possibles et futures recherches sont suggérées.
Modélisation et conception d’un coffrage réutilisable pour la fabrication de coques minces en béton de formes complexes
Authors: Boutemy Camille , Lebée Arthur , Skouras Mélina , Mimram Marc , Baverel Olivier
Published: October 2022

La construction de coques minces en béton est coûteuse en matériaux et en main d’œuvre à cause de la fabrication du coffrage qui génère une vaste quantité de déchets. Ces éléments non réutilisables ont un impact négatif sur l’ACV de la construction. Ces difficultés expliquent en partie pourquoi la construction de coques minces est devenue rare à la fin du XXème siècle malgré l’indéniable qualité architecturale qu’elles confèrent aux espaces créés. Cette recherche a pour objectif de modéliser et concevoir un nouveau système de coffrage économe en moyens, pour préfabriquer des éléments surfaciques en béton à partir de structures gonflables. Contrairement à des exemples historiques proposant des gonflables à simple peau, nous proposons de liaisonner deux membranes selon un motif. Composé de courbes, le motif est conçu afin qu’une fois les membranes gonflées, la métrique du plan varie de manière non uniforme et génère une surface en trois dimensions selon le theorema egregium de Gauss. Le dessin du motif d’assemblage est guidé par un outil numérique capable de simuler précisément une forme gonflée en 3D à partir d’un motif de soudure en 2D. Cette méthode de fabrication serait automatisable et transposable à plus grande échelle. L’article décrira les principes géométriques et l’outil de simulation numérique. Nous présenterons une application, la fabrication d’un coffrage gonflable et la construction d’une coque mince en béton.
Mütterliche Depressivität als Prädiktor
kindlicher Verhaltensauffälligkeiten
Authors: Singer Dominique
Published: October 2022

Liebe Leserinnen und Leser,

in der vorliegenden Ausgabe der Zeitschrift für Geburtshilfe und Neonatologie
(ZGN) findet sich eine prospektive Studie, in der an 161 Erstgebärenden und
ihren Kindern mittels standardisierter Fragebögen der Zusammenhang zwischen
peripartalem Wohlbefinden bzw. mütterlichem Bindungsstil einerseits und
frühkindlicher Entwicklung (bis zum 18. Lebensmonat) andererseits untersucht
wurde. Dabei ergaben sich nicht nur einige auf den ersten Blick verblüffende
Resultate: so etwa, dass Mütter, die in ihrem Beruf belastet waren, Kinder
mit weniger Verhaltensauffälligkeiten hatten als jene, die nicht belastet,
und jene, die noch zu Hause waren; oder, dass Kinder, die 4–6 Monate alt
gewesen waren, als ihre Mütter angefangen hatten zu arbeiten, sich in allen
Verhaltenskategorien am wenigsten auffällig zeigten. Es ergab sich auch und
vor allem ein eindeutiger Zusammenhang zwischen der Häufigkeit depressiver
Symptome der Mütter und der Rate späterer
Verhaltensauffälligkeiten der Kinder. Die Autor*innen leiten daraus
die Forderung nach einer verbesserten Früherkennung peripartaler
Depressivität als Baustein der Prävention frühkindlicher
Entwicklungsstörungen ab.

Published: October 2022

Context Golfo Dulce is a wintering ground of the south-eastern Pacific population of humpback whales. Habitat use and spatial preferences of whales during their reproductive season must be addressed to effectively conserve this species. Aims This study aims to determine spatial segregation depending on humpback whale group composition (groups that included mother–calf dyads versus adult-only groups). Methods Spatial aggregation was assessed using sightings per unit of effort from June to October, 2010–2019. The group preferences were analysed as a function of water depth and distance from the coast, and habitat use was characterised using behavioural data. Key results Our SPUE analysis showed important locations used by humpback whales. The mother–calf groups were present in waters <80 m deep, and their main behaviour was resting (nursing and social). Adult-only groups were in the deeper waters, and the main behaviours were social breaching and travelling. Spatial preferences and behaviour data allowed the identification of critical nursing areas near potential mating grounds. Conclusions and implications Our study has highlighted the need for inshore habitat protection, and these habitat-use patterns should be considered when designing effective conservation and management strategies for marine spatial planning.
Myth of identity
Authors: Yu Alice Fengyuan
Published: October 2022

This study delves into the stylization of a unique and dynamic Hong Kong identity through examining a series of
Cantonese standup comedies performed by the Hong Kong comedian, Wong Tze-wah, from 1993 to 2003. It explains the ways that Wong’s
standup comedies become the stylistic and semiotic resources which not merely iconically and symbolically represent the reality of
Hong Kong society; rather, they index many modalities of Hong Kongers’ questioning of authenticity and the relationship between
China and Hong Kong. It suggests that the comic performance, as a meaning-making process, helps to shape and reproduce the local
ideologies of identity, and to challenge the power underlying the discourse of China-Hong Kong relations.
The sociopragmatic nature of interjections in Early Modern English drama comedy
Authors: Lutzky Ursula
Published: October 2022

Interjections have been studied for all periods in the history of English, ranging from the study of Old English
exclamations such as hwaet (Brinton 2017) to the pragmatic functions
of forms such as oops in Present Day English (Lutzky and Kehoe 2017).
The Early Modern English (EModE) period represents a turning point as it witnessed an increase in dialogic and speech-related text
types, including drama comedy and trial proceedings. Nevertheless, despite recent advances in the compilation and especially the
sociopragmatic annotation of corpora, EModE pragmatic markers have not been studied extensively over the last decade. This article
addresses this gap by offering an investigation into the sociopragmatic nature of interjections in EModE drama comedy. It is based
on the sociopragmatically annotated Drama Corpus which includes a total of 242,561 words from the period 1500 to 1760. Taking a
data-driven, form-to-function mapping approach, this study explores the use of interjections in the Drama Corpus
with a focus on their distribution according to sociopragmatic variables. The aim of this study is to contribute to reaching a
more comprehensive understanding of pragmatic marker use in EModE.
When French becomes Canadian French
Authors: Bowker Lynne , Blain Frédéric
Published: October 2022

In late 2020, the free online translation tool Microsoft Translator began to offer the option of translating into “French (Canada)” as a target language, alongside the previously offered “French”. Using a list of ten COVID-19 terms previously identified byBowker (2020)as having different equivalents in Canadian French and European French, we evaluate the ability of Microsoft Translator to localize these terms into the two varieties of French. The findings indicate that while this tool does a good job of localizing the terms into Canadian French, it also uses a high number of Canadian French terms when the target language is set to “French”. One potential reason for this may be that the corpus used to train the tool for “French” contains a disproportionate number of examples from Canadian sources, and so there may be a problem of bias where the tool is amplifying Canadian French in the machine translation output.
Translation Studies fifty years on

Published: October 2022

Translanguaging refers to the dynamic meaning-making process whereby multilingual language users make full use of their communicative repertoires by crossing the boundaries between named languages and other semiotic and modal resources (García and Li 2014). Director Bong Joon-ho is well-known for utilising such border-crossing practices in his films, specifically, for his strategic and creative use of multiple languages and translation. He also extends this practice to his live interviews where an interpreter is usually present. This article focuses on understanding Director Bong Joon-ho’s translanguaging practices in interviews. It first examines how he communicates through translanguaging and for what purposes, and secondly how he and his interpreter collaboratively and strategically make use of translation as translanguaging. Through the study, we wish to make the case for (a) approaching translation as collaborative translanguaging practices and an act of democratisation, and (b) understanding translanguaging practices in connection with speakers’ positioning and experience in navigating values and ways of speaking which may be culturally and linguistically specific. These translanguaging practices provide powerful arguments against any assertion that named languages exist as separate and discrete systems, challenge the default position of English as the lingua franca in global communication, and offer a corrective to the prestige and power associated with English.

Published: October 2022

Recently an individualisation algorithm has been developed and shown to significantly improve the diagnostic accuracy of creatine kinase (CK) and urea in endurance sports and Badminton. In this study, the applicability and benefit of this algorithm was evaluated using repeated measures data from 161 professional German soccer players monitored during the 2015–2017 seasons. Venous blood samples were collected after a day off (recovered state) and after a minimum of two strenuous training sessions within 48 h (non‐recovered state) and analysed for CK and urea. Group‐based reference ranges were derived from that same dataset to ensure the best possible reference for comparison. A z‐test was conducted to analyse differences in error rates between individualised and group‐based classifications. CK values for the individualised approach showed significantly lower error rates in the assessment of muscle recovery compared to both a population‐based (p < .001; z‐value: −17.01; test‐pass error rate: 21 vs. 67%; test‐fail: 19 vs. 64%) and a group‐based cut‐off (p < .001; z‐value: −15.29; test‐pass error rate: 65%; test‐fail: 67%). It could be concluded that the assessment of muscle recovery in soccer using individualised interpretations of blood‐borne markers may offer higher diagnostic accuracy than a population‐based and a sample‐specific group‐based approach.

The front-end electronics of the ATLAS muon drift-tube chambers will be upgraded in the experiment’s phase-II upgrade to comply with the new trigger and read-out scheme at the HL-LHC. A new amplifier shaper discriminator chip was developed in 130 nm Global Foundries technology for this upgrade. A preproduction of 7500 chips was launched in 2019 and tested in 2020. The functionality of the chips, the test set-up and test procedure and results showing a yield of 93% are presented. The certification of the preproduction was followed by the production of 80,000 chips in fall 2020. The tests of a sample of 2949 preproduction and 1174 production chips gave a production yield > 93%.
Hill-type, bioinspired actuation delivers energy economy in DC motors
Authors: McGrath Jake , Alvarado José
Published: October 2022

Electromagnetic motors convert stored energy to mechanical work through a linear force–velocity (FV) relationship. In biological systems, however, muscle actuation is characterized by the hyperbolic FV mechanisms of the Hill muscle—in which a parameter α characterizes the degree of nonlinearity. Previous work has shown that bioinspiration in human-engineered systems can contribute favorable mechanical attributes—such as energy efficiency, self-stability, and flexibility, among others. In this study, we first construct an easily amendable, bioinspired electromagnetic motor which produces FV curves that mimic the Hill model of muscle with a high degree of accuracy. A proportional-integral-differential (PID) controller converges the characteristically linear FV relationship of a DC motor to nonlinear Hill-type force outputs. The bioinspired electric motor does a fixed amount of work by lifting a 147.5 g mass, and we record the translational velocity of the mass and the nonlinear applied force of the motor. Under optimized gain coefficients in the PID, the bioinspired motor achieves agreement of

with the Hill muscle model. Studies have shown that designing biologically inspired actuators produce comparatively energy efficient systems. We investigate the energy economy of actuating our motor with nonlinear, Hill-type forces in direct comparison with conventional linear FV actuation techniques. We find that the bioinspired motor delivers energy economy with respect to energy consumption and conversion: the nonlinear, Hill-type DC motor reduces the energetic cost of actuation when delivering a fixed amount of mechanical work.

Authors: Asruddin Mohd , Khan Amir Ali , Singh Gyanendra , Dass Sachin , Jaglan Saurabh
Published: October 2022

Accident occurring at junctions is a major problem in India. As per the annual report 2019, almost 50% of road accidents in India occurred at junctions. In this study, an attempt has been made to study the safety aspects of minor road junctions on MDR 132 in the Palwal District of Haryana State. The main aims of the present study are to study the safety aspects of minor road junctions on MDR-132 from Nuh to Hodal by analyzing various features of minor road junctions like markings, signs, shoulders, sight distances, lightings, median, etc., and to give suggestions to minimize the accidents. Two types of data were collected. One is from the field, and the other is from registered FIRs. The first one includes pavement width, shoulder width, marking, speed breaker, signs, types of junctions, sight distance, etc. The second one includes hitting and victim vehicle, fatal, grievous and minor injury, visibility, age of the victim, etc. It was observed that the number of accidents is being affected by various road parameters. For example, the number of accidents at uncontrolled junctions is decreasing as pavement width, shoulder width, sight distance, and presence of speed breaker [especially on minor roads] are increasing. Similarly, it was also observed that the number of fatalities decreased as the considered road parameters were increased.

Published: October 2022

Model experimentation was used to examine the flow properties above the perpendicular descents with a grid roof, or the “grid drop-type dissipators”. The software ANSYS FLUENT R 15 is used to analyse the fluid flow above the impediment and research of the flow arrays and hydraulic characteristics. The purpose of the flow analysis is to examine how subcritical flow develops upstream and to let the water flowing downstream to slow down the flow of water to prevent erosion downstream. The pool formation, mixing zone, pressure distribution, and velocity distribution were all analysed using the Ansys software. The findings show that, in comparison to a simple vertical drop, the suggested hydraulic structure removes undesirable flow situations and serves as the foundation for a more operative flow rheostat arrangement. It is shown that, in comparison to a straight vertical drop, the scattering/circulation process in the pool surges the velocity grade, the impetus altercation, and, as a result, the energy dissipation.

This study aimed to determine the strength and chloride content of marine concrete if fly ash and silica fume were used to replace a portion of the conventional Portland cement (OPC). The study was done so that these goals could be reached. W/C of 0.42 to make M30 grade concrete. Even though the number of parts that go into making OPC concrete is the same, using SP cuts the amount of water needed to make mixed concrete by 20%. Several different experiments that were done with different mixtures back up this conclusion. Compressive strength, flexural strength, and split tensile strength are the three types of strength that have been looked at. For the durability test, water-soluble chloride (WSC) will be used. SEM, which stands for scanning electron microscopy, will be used for the microstructural analysis. According to the test results, the compressive strength of concrete that had been treated with dosages of SP and had 10% fly ash showed a degradation factor (DF) of less than 5% after being exposed to the elements for a year. Even though the concrete had been out in the weather, this was still the case. After 90 days, both the split tensile strength and the flexural strength have a DF of 0.95 percent, but the flexural strength only has a DF of 0.5 percent.

Published: October 2022

Concrete, an effective rigid material that acts as a barrier to restrict sound waves in buildings. This research study is mainly based on the experimental testing on the acoustic properties that can be induced in concrete using perlite material. When sound passes through the concrete having lower density, it gets dispersed and the decibel of sound is decreased, thus it acts as a better sound insulator. Concrete specimens along with the addition of perlite are tested for their strength and optimum dosage of perlite to be added in order to have a improved acoustic behaviour. It is identified that with 5% replacement of perlite for cement in concrete, improved the acoustic behaviour of concrete by 26.12%. In order to have adequate strength in concrete, 30% GGBS is partially replaced for cement and hence the strength is improved by 12.5%. From this work, it is depicted that perlite can act as a better material to make concrete as a sound insulator. This composite can be used in various applications in buildings as precast insulation panels, bricks, tiles etc to make sound insulation.

Published: October 2022

The present confront among the construction industry is to curtail the production of the ordinary Portland cement (OPC), which is directly responsible to the emission of harmful gases like CO2during the manufacturing and also depletion of natural resources like lime stone, coal etc. The present investigation is focused to develop the sustainable concrete using complementary cementing materials (CCMs) for the sustainable environment. Ground granulated blast furnace slag (GGBS) is one among the sustainable alternatives for ordinary Portland cement (OPC) to produce green concrete and because of its high calcium silicate content it has excellent cementious content and has been used in the construction industry for years as a replacement for ordinary Portland cement (OPC). The paper presents the performance of the Binary concrete made by replacing the OPC with high volume GGBS up to 70%. In total 6 binary mixtures and conventional mix were prepared for M40 grade of concrete. Flow characteristics and strength properties (compression, split tensile and flexural strength) are determined for both conventional and binary concrete at the age of 7, 28, 60, 90 days. The test results proved that the binary concrete had considerable performance regarding workability and strength of the binary concrete over conventional mix.

Published: October 2022

The low density, lightweight, easy processing and biodegradability nature of Natural fiber-reinforced polymer composite have gained enough attention from many researchers and scientists. Kapok Fiber (Ceiba pentandra) is a natural cellulosic fiber have a hollow microtubular structure and a high degree of hollowness. The hand lay-up technique has been adopted for kapok fiber-reinforced epoxy polymer composite fabrication with different fiber loading(2, 3, 4, 5, 6 and 7 wt %). The mechanical strength of kapok fiber-reinforced polymer epoxy composite is investigated through the flexural and tensile test. The best flexural and tensile performance is observed at 5 wt% loading of kapok fiber. To increase compatibility between fiber and epoxy matrix dewaxing process is adopted. The effect of dewaxing on cellulose crystallinity, crystallinity size, surface morphology, elemental composition and functional groups of fiber are studied. The roughness of the fiber surface increases after dewaxing due to the partial removal of non-cellulosic compounds like lignin, pectin, wax and some oily substances. The increase in fiber surface roughness and cellulose crystallinity index by chemical treatment made a strong interlocking at the fiber-matrix interface. The effect of dewaxing on mechanical strength is also studied to fabricate the composite for the benefit of society.

Published: October 2022

Deposition of used foundry sand in landfills causing environmental hazard has been generating focus to develop alternate methods of disposal or applications. Research works in the recent period have been concentrated towards utilization of foundry sand in construction industry. Results with regard to the use of foundry sand in manufacturing construction materials like bricks and concrete have been quite promising and have provided a lot of scope for production of green materials. The present research work aims to study the mechanical and durability characteristics of high strength concrete containing foundry sand as a partial replacement of river sand. River sand was replaced with 20%, 40%, 60%, 80% and 100% foundry sand. Properties like slump, compressive strength, ultrasonic pulse velocity, water absorption, RCPT values were evaluated to report the performance characteristics. The results indicate that it is possible to achieve strengths greater than 50MPa upto 60% replacement of fine aggregate and nominal strengths at higher replacement percentages. Durability studies indicate that concretes containing foundry sand had inferior properties, however, all the values reported were well below the allowable limits.

Authors: Gayitri Keerthana Y , Rakesh S , Jyothirmai A
Published: October 2022

Concrete, which is now the second most consumed substance in the world after the water has cement as the main ingredient. There is a continuous increase in pollution due to the enormous volumes of CO2 that are released into the atmosphere during the production of cement. The invention of geopolymer concrete proceeded to reduce environmental pollution by replacing cement with supplementary cementitious ingredients such as flyash, GGBS, metakaolin, silica fume, etc. With sodium hydroxide and sodium silicate functioning as caustic activators, the current research intends to develop a ternary blend flyash-based geopolymer mortar using flyash, GGBS, and alccofine as supplementary cementitious ingredients. Depending on how well binary mixes performed in terms of compressive strength, the proportions of the materials in the ternary blend were fixed. Two binary blends, flyash-GGBS and flyash-alccofine, were produced using a NaOH solution with an 8M concentration and different ratios. The ratio of sodium hydroxide to water glass was 1:2.5. Alccofine was substituted by 2.5%, 5%, 10%, and 20% in their respective blends with flyash, whereas GGBS was replaced by 10%, 20%, 40%, and 80%. On the binary mixtures, a compressive strength test was performed. The results demonstrated that when 40% GGBS and 20% alccofine were replaced with flyash in their respective blends, the compressive strength was increased. The composition of the ternary blend was established as being, 40% flyash, 40% GGBS, and 20% alccofine. Normal consistency and compressive strength tests were conducted on different proportions of the ternary blend. The replacement of 40% GGBS and 20% alccofine yielded the greatest values of normal consistency and compressive strength of all the ternary mixes. The outcomes demonstrated that the binary mixtures’ chosen optimal ternary blend proportion was acceptable.

OC-055 THE INCIDENCE OF EXTRACTION SITE INCISIONAL HERNIA AFTER MINIMALLY INVASIVE COLORECTAL SURGERY: A SYSTEMATIC REVIEW AND META-ANALYSIS
Authors: Van Egmond S , Den Hartog F , Poelman M , Menon A , Kleinrensink G J , Lange J , Tanis P , Deerenberg E
Published: October 2022

Aim

Minimally invasive colorectal surgery reduces surgical trauma with better preservation of abdominal wall integrity, but the extraction site is still at risk of incisional hernia (IH). This study aimed to determine pooled incidence of IH for each type of extraction site, and to compare IH rates after midline, non-midline and Pfannenstiel extraction.

Methods

A systematic review and meta-analysis was conducted using PRISMA guidelines. Single-armed and multiple-armed cohort studies, and randomized controlled trials regarding minimally invasive colorectal surgery were queried from five databases. Outcomes were pooled and compared with random-effects, inverse-variance models. Risk of bias was assessed using the Cochrane ROBINS-I and RoB 2 tools.

Results

Thirty-six studies were included, totalling 11,788 patients. Pooled extraction site incisional hernia (ESIH) rate was 16.0% for midline (n=4081), 9.3% for umbilical (n=2425), 5.2% for transverse (n=3213), 9.4% for paramedian (n=134) and 2.1% for Pfannenstiel (n=1449). ESIH occurred significantly more with midline extraction in comparison to Pfannenstiel (Odds Ratio (OR) 8.4 [3.5;20.0]). Non-midline extraction (transverse and paramedian) showed a significantly lower OR for IH compared to midline extraction (midline and umbilical). Pfannenstiel extraction resulted in significantly lower OR for ESIH compared to midline (OR 0.12 [0.050;0.30]), transverse (OR 0.25 [0.13;0.50]) and umbilical (OR 0.072 [0.033;0.16]) extraction sites. The risks of surgical site infection and surgical site occurrence were not significantly different in any analyses.

Conclusions

Specimen extraction through a Pfannenstiel incision is the preferred method in minimally invasive colorectal surgery. In cases where Pfannenstiel extraction is not possible, surgeons should avoid midline specimen extraction.

Published: October 2022

Aim

The short-term results of the use of seprafilm® as a reinforcement of the peritoneum are presented.

Material and Methods

Seprafilm® was used in 5 patients with large midline and lateral incisional hernia in which Transversus Abdominis Release Technique was performed in which it was necessary to explant mesh previously. This weakness of the peritoneum was reinforced with the seprafilm® plates, to isolate the intra-abdominal contents from the mesh.

Results

The patients treated had an average stay of 6.6 days. All of them carried drains. There were no infectious complications in surgical site. There were no prolonged pain. All of them began tolerance the day after the surgery. At one month of the surgical intervention, there were no signs of infection, seroma or higher pain than 3 on the EVA scale.

Discussion

Post-operative adhesions to mesh are related to intestinal fistulas. The use of preperitoneal space to place the mesh is a good option, although sometimes it can have continuity problems, especially when there are explants of previous materials. The use of barrier materials is appropriate in these cases.

Ecology and social behavior of the social vole Microtus socialis: A generalized review
Authors: Gromov Vladimir S
Published: October 2022

The present review is a compilation of the published data on the ecology and social behavior of the social vole. Field studies provide evidence that these voles live in family groups consisting of 1 adult male, 1 or 2 breeding females, and their offspring (1 or 2 litters). The social vole is capable of year-round reproduction, but in arid regions, the voles demonstrate seasonality in breeding. The mating system of this species may be defined as behavioral monogamy. A typical feature of the space use system is territoriality characterized by a locus-dependent dominance in relationships between neighboring breeding pairs as well as family groups. The family group social organization may be defined as consistent relationships without a dominant hierarchy. Social voles are cooperative in defending their territories, constructing burrows, digging underground tunnels, maintaining nests, and raising young. Cooperation appears to enhance the survival of family groups of this species under the extreme climatic conditions of Central Asia.
“Women, Men, Boys, and Girls”: Analyzing the Implementation of Women, Peace, and Security in the United States
Authors: Henshaw Alexis
Published: October 2022

More than 20 years after the passage of UN Security Council Resolution 1325 (2000), the United States is still in the process of institutionalizing its strategy on Women, Peace, and Security (WPS). While the Women, Peace, and Security Act (2017) established a legal mandate by which federal agencies are obligated to demonstrate efforts to mainstream gender in foreign policy, timely implementation has been hindered by confusion and disagreement over the aims of WPS. Drawing on elite interviews with 35 stakeholders working on WPS implementation across relevant institutions, I argue that implementation efforts in the United States have resulted in understandings of WPS that parse the agenda as an extension of familiar issues like the War on Terror, debates over reproductive rights, and issues of sexual harassment and equal opportunity. I demonstrate how feminist security studies and cognitive approaches to foreign policy analysis explain these outcomes.

Air traffic control (ATC) is a safety-critical, cooperative work domain, which faces usability challenges due to technology driven development in the past. In this work, we followed a user-centered design process to explore how novel interaction concepts increase user experience in ATC. Based on controllers’ needs we envisioned one unified interface together with three possible interaction concepts (the mouse interface, flight-dial and tangible interface) addressing different aspects of ATC. We prototypically implemented the interaction concepts and iterated each prototype based on feedback from 24 controllers. Qualitative data from these iterative formative evaluations indicated that controllers prefer interfaces that are efficient to use, minimalistic, customizable and context sensitive. A summative evaluation (N = 12) showed that the hedonic quality of all three concepts were higher compared to the system currently in use. Our results and insights can provide guidance and inspiration for the future design of ATC interfaces.

Nosema bombycis Naegeli (Dissociodihaplophasida: Nosematidae), an obligate intracellular parasite of the silkworm Bombyx mori, causes a devastating disease called pébrine. Every year pébrine will cause huge losses to the sericulture industry worldwide. Until now, there are no effective methods to inhibit the N. bombycis infection in silkworms. In this study, we first applied both the novel protein degradation Trim-Away technology and NSlmb (F-box domain-containing in the N-terminal part of supernumerary limbs from Drosophila melanogaster) to lepidopteran Sf9-III cells to check for specific degradation of a target protein in combination with a single-chain Fv fragment (scFv). Our results showed that the Trim-Away and NSlmb systems are both amenable to Sf9-III cells. We then created transgenic cell lines that overexpressed the protein degradation system and N. bombycis chimeric scFv targeting spore wall protein NbSWP12 and evaluated the effects of the insect transgenic cell lines on the proliferation of N. bombycis. Both methods could be applied to cell lines and both Trim-Away and NSlmb ubiquitin degradation systems effectively inhibited the proliferation of N. bombycis. Further, either of these degradation systems could be applied to individual silkworms through a transgenic platform, which would yield individual silkworms with high resistance to N. bombycis, thus greatly speeding up the process of acquiring resistant strains.
Virtual Ultrasound Training in a Multinational Teaching Program
Authors: Ward Samantha , Palma James
Published: October 2022

Introduction

Before the COVID-19 pandemic, a 1-week in-person Clinical Ultrasound Course was taught in African nations as part of a U.S. Department of State-funded program that supports and trains African peacekeepers serving with the United Nations and African Union. In order to maintain active engagement with host nations despite the travel restrictions due to the COVID-19 pandemic, portions of the course were taught virtually in 2021 to providers in Ghana, Senegal, and Rwanda. An abbreviated course was delivered covering the Focused Assessment with Sonography in Trauma (FAST) trauma exam and vascular access. The goal of this study is to assess the effectiveness of the Clinical Ultrasound Course while taught in a virtual classroom.

Materials and Methods

Thirty-six participants enrolled in the program. Participants completed a pre-course survey before the training. Training consisted of a pre-recorded lecture followed by hands-on ultrasound instruction. After the training, participants completed a post-course survey. Eight participants were excluded from the study because they did not complete both surveys. Survey questions assessed the participants’ comfort with ultrasound mechanics and the FAST exam. Participant responses were measured utilizing a visual analog scale.

Results

Based on survey results, all participants gained a better understanding of the indications and limitations of the FAST exam from the virtual Clinical Ultrasound Course. All participants also felt more comfortable using ultrasound in clinical practice than they did before the course. Ghanaian and Senegalese participants showed greater improvement in all areas studied than Rwandan participants. This is likely due to the fact that the Rwandan hospital system had prior ultrasound training and a higher baseline understanding than their counterparts. The Rwandan hospital system had previously completed the in-person sessions of the Clinical Ultrasound Course and therefore had some institutional knowledge, while the Ghanaians and Senegalese took the course for the first time during this study.

Conclusion

Virtual delivery of the Clinical Ultrasound Course was successful. Participants felt more comfortable in all aspects of ultrasound taught during the course and indicated that they were more likely to use ultrasound in clinical practice. This demonstrates that virtual ultrasound teaching is a viable option for international educational programs in the future.

OBJECTIVES:

Evaluate the safety and efficacy of the Janus kinase (JAK)1/JAK2 inhibitor ruxolitinib in COVID-19–associated acute respiratory distress syndrome requiring mechanical ventilation.

DESIGN:

Phase 3 randomized, double-blind, placebo-controlled trial Ruxolitinib in Participants With COVID-19–Associated Acute Respiratory Distress Syndrome Who Require Mechanical Ventilation (RUXCOVID-DEVENT; NCT04377620).

SETTING:

Hospitals and community-based private or group practices in the United States (29 sites) and Russia (4 sites).

PATIENTS:

Eligible patients were greater than or equal to 12 years old, hospitalized with severe acute respiratory syndrome coronavirus 2 infection, and mechanically ventilated with a Pao
2/Fio
2 of less than or equal to 300 mm Hg within 6 hours of randomization.

INTERVENTIONS:

Patients were randomized 2:2:1 to receive twice-daily ruxolitinib 15 mg, ruxolitinib 5 mg, or placebo, each plus standard therapy.

MEASUREMENTS AND MAIN RESULTS:

The primary endpoint, 28-day mortality, was tested for each ruxolitinib group versus placebo using a mixed-effects logistic regression model and one-tailed significance test (significance threshold: p < 0.025); no type 1 error was allocated to secondary endpoints. Between May 24, 2020 and December 15, 2020, 211 patients (age range, 24–87 yr) were randomized (ruxolitinib 15/5 mg, n = 77/87; placebo, n = 47). Acute respiratory distress syndrome was categorized as severe in 27% of patients (58/211) at randomization; 90% (190/211) received concomitant steroids. Day-28 mortality was 51% (39/77; 95% CI, 39–62%) for ruxolitinib 15 mg, 53% (45/85; 95% CI, 42–64%) for ruxolitinib 5 mg, and 70% (33/47; 95% CI, 55–83%) for placebo. Neither ruxolitinib 15 mg (odds ratio, 0.46 [95% CI, 0.201–1.028]; one-sided p = 0.029) nor 5 mg (odds ratio, 0.42 [95% CI, 0.171–1.023]; one-sided p = 0.028) significantly reduced 28-day mortality versus placebo. Numerical improvements with ruxolitinib 15 mg versus placebo were observed in secondary outcomes including ventilator-, ICU-, and vasopressor-free days. Rates of overall and serious treatment-emergent adverse events were similar across treatments.

CONCLUSIONS:

The observed reduction in 28-day mortality rate between ruxolitinib and placebo in mechanically ventilated patients with COVID-19–associated acute respiratory distress syndrome was not statistically significant; however, the trial was underpowered owing to early termination.

Published: October 2022

Text-mining algorithms can identify the most prevalent factors of risk-benefit assessment on the use of complementary and integrative health approaches that are found in healthcare professionals' written notes. The aims of this study were to discover the key factors of decision-making on patients' complementary and integrative health use by healthcare professionals and to build a consensus-derived decision algorithm on the benefit-risk assessment of complementary and integrative health use in diabetes. The retrospective study of an archival dataset used a text-mining method designed to extract and analyze unstructured textual data from healthcare professionals' responses. The techniques of classification, clustering, and extraction were performed with 1398 unstructured clinical notes made by healthcare professionals between 2019 and 2020. The most important factor for decision-making by healthcare professionals about complementary and integrative health use in patients with diabetes was the ingredients of the product. Other important factors were the patient's diabetes control, the undesirable effects from complementary and integrative health, evidence-based complementary and integrative health, medical laboratory data, and the product's affordability. This exploratory text-mining study provides insight into how healthcare professionals decide complementary and integrative health use for patients with diabetes after a risk-benefit assessment from clinical narrative notes.
