The Pre-main Sequence: Challenges and Prospects for Asteroseismology
Authors: Zwintz Konstanze , Steindl Thomas
Published: June 2022

Stars do not simply pop up on the main sequence. Before the stars arrive on the zero-age main sequence, they form in the collapses of molecular clouds, gain matter through accretion processes, and compress their cores until hydrogen can burn in full equilibrium. Although this evolutionary phase lasts a relatively short time, it is the imprint of these important physical processes that is often ignored by simplified assumptions. While asteroseismology offers a great tool to investigate these physical processes, studying pre-MS oscillations in turn has the potential to further advance the field. Asteroseismology of pre-main sequence stars faces observational and theoretical challenges. The remnants of their birth environment which is often still surrounding the young stars causes variability that can interfere with the signal of pulsations. The lack of long time-base satellite observations in addition limits the applications of the method. Theoretical models of pre-main sequence stars include several assumptions and simplifications that influence the calculation of pulsation frequencies and excitation properties of pulsation modes. Keeping all this in mind, the prospects for pre-main sequence asteroseismology are manifold. An improved understanding of the structure of young stellar objects has the potential to answer some of the open questions of stellar evolution, including angular momentum transport and the formation of magnetic fields. While gyrochronology, for example, struggles to determine the ages of the youngest clusters, pulsations in pre-main sequence stars can function as an independent age indicator yielding higher precision for single stars. The increasing interest of stellar astrophysics in general to investigate the formation and early evolution of stars and planets illustrates the growing importance of pre-main sequence asteroseismology. In this work we discuss its potential for an advancement of our understanding of stellar structure and evolution.

Published: June 2022

Background

Enhanced recovery after surgery (ERAS), a new clinical surgical concept, has been applied in many surgical disciplines with good clinical results for the past 20 years. Bibliometric analysis is an effective method to quantitatively evaluate the academic productivity. This report aimed to perform a scientometric analysis of the ERAS research status and research hotspots.

Methods

Comprehensive scientific mapping analysis of a wide range of literature metadata using the scientometric tools, including the Bibliometrix R Package, Biblioshiny, and CiteSpace. Data were retrieved from the Web of Science Core Collection database of original articles from 2001 to 2020. Specific indicators and maps were analyzed to show the co-authorship, co-institute, co-country, co-citation, and international cooperation. Automatic literature screening, unsupervised cluster filtering, and topic cluster identification methods were used to display the conceptual framework and thematic evolution.

Results

A total of 1,403 research projects drafted by 6,966 authors and published in 413 sources were found. There was an exponential growth in the number of publications on ERAS. There were 709 collaborations between authors from different countries, and the US, China, and the UK had the greatest number of publications. The WORLD JOURNAL OF SURGERY, located in Bradford’s Law 1, had the highest number of published articles (n = 1,276; total citations = 3,193). CiteSpace network analysis revealed 15 highly correlated cluster ERAS studies, and the earliest study was on colonic surgery, and ERAS was recently applied in cardiac surgery. The etiology of ERAS is constantly evolving, with surgery and length of hospital as the main topics. Meta-analyses and perioperative care have tended to decline.

Conclusion

This is the first scientometric analysis of ERAS to provide descriptive quantitative indicators. This can provide a better understanding of how the field has evolved over the past 20 years, help identify research trends, and provide insights and research directions for academic researchers, policymakers, and medical practitioners who want to collaborate in these areas in the future.
Non-Surgical treatment Versus Surgery for Iatrogenic Femoral Artery Pseudoaneurysms: Systematic Review and Meta-Analysis
Authors: Wu Haoliang , Zhang Liwei , Zhang Cong , Xie Boao , Lou Chunyang , Liu Yuanfeng , Bai Hualong
Published: June 2022

Objectives

This study compared results of non-surgical treatment (compression and ultrasound guided thrombin injection (UGTI)) and surgery to treat iatrogenic femoral artery pseudoaneurysms.

Methods

PubMed and Embase databases were searched up to October 2021. Primary outcome measure was success rate, and other outcomes examined were complication rate, reintervention rate. Two authors independently reviewed and extracted data. Data were presented as the odds ratios (ORs) with 95% confidence intervals (CIs). The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to appraise the quality of the body of evidence.

Results

Eight studies were included. A total of 623 patients with pseudoaneurysm undergoing treatment were included, of which 163 subjects underwent surgery, 397 subjects underwent compression, and 63 subjects underwent UGTI. The success rate was significantly lower in the non-surgery group (OR 0.24, 95% CI, 0.08–0.69, I2 = 0%). The complication rate was significantly lower in the non-surgery group (OR 0.10, 95% CI, 0.03 –0.29, I2 = 0%). Patients in the non-surgery group tended to have a lower, but statistically insignificant, reintervention rate (OR 0.11, 95% CI, 0.01–1.06, I2 = 35%). Further, the GRADE assessment showed that these results (success rate, complication rate, and reintervention rate) were of very low quality.

Conclusions

Available evidence shows that it is reasonable to regard non-surgical treatment as the primary treatment for iatrogenic femoral artery pseudoaneurysms, and surgery as a remedy after failure of non-surgical treatment in some cases.
Thymidine Kinase+/− Mammalian Cell Mutagenicity Assays for Assessment of Nanomaterials
Authors: Chen Tao , Dusinska Maria , Elespuru Rosalie
Published: June 2022

The methods outlined here are part of a series of papers designed specifically for genotoxicity assessment of nanomaterials (NM). Common Considerations such as NM characterization, sample preparation and dose selection, relevant to all genotoxicity assays, are found in an accompanying paper. The present paper describes methods for evaluation of mutagenicity in the mammalian (mouse) thymidine kinase (Tk) gene occurring in L5178Y mouse lymphoma (ML) cells and in the designated TK gene in human lymphoblastoid TK6 cells. Mutations change the functional genotype from TK+/− to TK−/−, detectable as cells surviving on media selective for the lack of thymidine kinase (TK) function. Unlike cells with TK enzyme function, the TK−/− cells are unable to integrate the toxic selection agent, allowing these cells to survive as rare mutant colonies. The ML assay has been shown to detect a broad spectrum of genetic damage, including both small scale (point) mutations and chromosomal alterations. This assay is a widely used mammalian cell gene mutation assay for regulatory purposes and is included in the core battery of genotoxicity tests for regulatory decision-making. The TK6 assay is an assay using a human cell line derived similarly via mutagenic manipulations and optimal selection. Details are provided on the materials required, cell culture methods, selection of test chemical concentrations, cytotoxicity, treatment time, mutation expression, cloning, and data calculation and interpretation. The methods describe the microwell plate version of the assays without metabolic activation.

Authors: Tume Lyvonne N. , Ungari Davide , Bannerman Fariba , Cuddihy Sean , Gnanalingham Claire , Phillips Hayley
Published: June 2022

Background: The COVID-19 pandemic has required healthcare workers to wear personal protective equipment (PPE), and although there is increasing awareness of the physical effects of wearing PPE, the literature has yet to be synthesised around this topic. Methods: A scoping review was conducted to synthesise existing literature on the physical effects of wearing PPE and identify gaps in the literature. A comprehensive search strategy was undertaken using five databases from 1995 to July 2020. Results: A total of 375 relevant articles were identified and screened. Twenty-three studies were included in this review. Studies were conducted across 10 countries, spanning 16 years from 2004 to 2020. Half (13/23) were randomised controlled trials or quasi-experimental studies, five surveys, two qualitative studies, two observational or case series and one Delphi study. Most (82%, 19/23) studies involved the N95 mask (either valved or unvalved). None specifically studied the filtering facepiece 3 mask. The main physical effects relate to skin irritation, pressure ulcers, fatigue, increased breathing resistance, increased carbon dioxide rebreathing, heat around the face, impaired communication and wearer reported discomfort. Few studies examined the impact of prolonged wear (akin to real life practice) on the physical effects, and different types of PPE had different effects. Conclusions: The physical effects of wearing PPE are not insignificant. Few studies examined the physiological impact of wearing respiratory protective devices for prolonged periods whilst conducting usual nursing activity. No ideal respirators for healthcare workers exist, and the development of more ergonomic designs of PPE is required.

Suyun hayatımızdaki yeri ve sağlıklı bir yaşam sürmemiz için suyun ne kadar önemli olduğu herkes tarafından kabul gören bir gerçektir. Su günlük hayatta içecek olarak kullanılmasının yanında ayrıca çeşitli yöntemler aracılığıyla tedavi unsuru olarak da tercih edilmektedir. Çalışmamızda şizofreni hastalarına etkiyen iki nörotransmitter, dopamine (C8H11NO2) veserotonin (C10H12N2O) üzerinde duruldu. Bu iki nörotarsmitterin üç boyutlu çizimleri gaussian programı aracılığıyla yapıldı. Bu iki nörotrasmitterin moleküller yapısının yeterli miktarda su ile etkileşmesiyle meydana gelen değişikliklere bakıldı. Moleküller yapıların su ile etkileşmesi ile bağ açılarında ve bağ uzunluklarındaki değişimler irdelenerek sinapsların elektrostatik ileti mekanizması ele alındı. Nörotransmitter iki yapının geometrik optizimazyonu Gaussian 09W programında HF (Hatree- Fock) hesaplama yöntemindeki TD-SCF metod ve LanL2DZ baz seti kullanılarak yapıldı. Geometrik optimizasyon sonucu oluşan moleküllerin en yüksek dolu moleküler orbital (HOMO) ve en düşük boş moleküler orbital (LUMO) değerlerinin hesaplamaları yapıldı.

Bu çalışma, sağlık profesyonellerinin meme kanseri risk düzeyini ve bu kanserin erken tanılanmasına yönelik sağlık inançlarını belirlemek amacıyla yapılmıştır. Tanımlayıcı tipteki bu çalışma, bir üniversitenin araştırma ve uygulama hastanesinde görev yapan 146 sağlık profesyoneli (137 hemşire ve 9 ebe) ile gerçekleştirilmiştir. Araştırmanın verileri, “Veri Toplama Formu”, “Meme Kanseri Risk Değerlendirme Formu” ve “Meme Kanseri Sağlık İnanç Modeli Ölçeği (MKSİMÖ)” kullanılarak toplanmıştır. Veriler tanımlayıcı istatistikler, bağımsız gruplarda t- testi ve tek yönlü ANOVA testi kullanılarak değerlendirilmiştir. Araştırmaya katılan sağlık profesyonellerinin yaş ortalaması 30.06±6.22 olup, %69.2’si kendi kendine meme muayenesi (KKMM) yapmaktadır. Hemşire ve ebenin %97.2’sinin meme kanseri açısından düşük riske sahip oldukları belirlendi. Üniversite mezunu ve gelir durumu iyi olanların, öğrenimleri sırasında KKMM konusunda eğitim alanların ve KKMM’sini yapanların MKSİMÖ’nin KKMM Öz-Etkiliği alt boyutundan aldıkları puan ortalamalarının diğerlerinden yüksek olduğu saptandı (p<0.05). Sağlık profesyonellerinin öğrenimleri sırasında KKMM konusunda eğitim alması, onların istenilen sağlık davranışlarının gerçekleşmesinde etkili olmaktadır. Bu nedenle sağlık profesyonellerinin mesleki eğitim müfredatlarına meme kanserinin erken tanılanmasına ilişkin eğitimin eklenmesi, onların olumlu sağlık inançlarının gelişmesine katkı sağlayacağı düşünülmektedir.
THE “FLIPPED CLASSROOM” MODEL: WHAT IT IS AND HOW IT WORKS
Authors: Gron Larysa , Antonenko Nataliia
Published: June 2022

The desire to learn ESL/EFL has skyrocketed worldwide due to technology development and blended learning. This constant demand forces teachers to develop new and functional approaches and methods to improve ESL/EFL teaching and learning processes, and one of these methods is blended learning. According to King (2016), "blended learning" is defined in many ways. However, all definitions have two things in common: asynchronous (online) and synchronous (face-to-face), which means that blended learning combines face-to-face and online instruction elements to assist teachers and students in the teaching process and education.

The modern standard of higher education reflects the need to form and improve foreign language communicative competence necessary for successful socialization as a tool for intercultural communication in the modern multicultural world. It becomes the starting point for pedagogical design, as the learning process requires completely new tools and methods. This article is devoted to description of the main principles of “flipped classroom” model in the process of teaching a foreign language.

The method's advantages manifest in the release of lesson time for performing creative tasks and including students in the active learning activity. The article describes the advantages and disadvantages of the "flipped classroom," the difficulties that arise in its implementation, and the positive effect that can be achieved by using this method in foreign language classes at the university.

Integrating component condition in long-term power system reliability analysis
Authors: Toftaker Håkon , Sperstad Iver Bakken
Published: June 2022

The electric power system is a critical infrastructure in which power transformers play a key role in linking together generation and end-use of electricity. The consequences of transformer breakdown can be significant, and aging transformers have a higher probability of failure. For decisions in asset management and power system development, it will therefore be useful to capture how deteriorating component condition affects failure probabilities and the overall reliability of the power system. Since such decisions have planning horizons of multiple years, the analysis should also capture similar time horizons. To this end, this paper proposes an analytical approach to power system reliability analysis (PSRA) accounting for time dependencies in the technical condition of components. An analytical PSRA methodology integrating a transformer condition model is extended to analysis horizons of multiple years. This analytical methodology is compared with a Monte Carlo simulation (MCS) approach to PSRA by applying both to a realistic case study. The comparison validates the analytical approach by showing that the inaccuracies its approximations introduce are negligible, at least for the considered case. This means that the proposed methodology can be a computationally viable alternative to MCS methods, especially when it is too time consuming to assess the impact of different scenarios with sufficient statistical precision using MCS. However, drawbacks with the analytical approach for further extensions of the methodology are also discussed.
Disability on drama TV: How attitudes about disability in the US relate to viewing frequency and identification with a character with a disability on “Glee”
Authors: Lorenz Emily P. , Frisby Cynthia M.
Published: June 2022

Although the relationship between attitudes about minorities and television portrayals has been a long-studied topic, individuals with disability have often been left out. This study demonstrates how exposure to disability portrayal on television relates to attitudes about individuals with disability. An online survey examined respondents’ viewing habits of the television program “Glee,” which had a main character, Artie, who used a wheelchair, and how viewing this representation related to attitudes about individuals with disability. The results showed that identification with Artie is correlated with frequency of viewing and to more positive attitudes about individuals with disability. In addition, any viewing of “Glee,” rather than frequency, was related to more positive attitudes about individuals with disability. While findings were explained through social cognitive theory and identification, results did not line up with cultivation theory. The findings demonstrate that viewing a TV show with a character with a disability relates to more positive attitudes about individuals with disability and hopes to encourage more inclusion in the media landscape.

Published: June 2022

Abstract—A water management system is being developed in Politeknik Negeri Samarinda (Polnes). The system consists of a number of sensor node (SN) that is always connected to a gateway/sink. Communication network between SNs and gateway is considered to utilize radio technology. As the campus area reaches 10 hectare, long range (LoRa) radio technology might be the candidate. Eventhough LoRa, in its specification, could cover the distance of around 15 km in line of sight condition, Polnes campus that has hilly terrain with several storey buildings may reduce the coverage of LoRa. Hence, in this research, the received signal strength (RSSI) was measured to find the possibility of LoRa being the communication network infrastructure. At the location where the gateway would be installed, a 433 Mhz LoRa transmitter was operated to continuously send data packets. A LoRa receiver was brought to every future SN locations to measure the RSSI. The measurement by the receiver that was equipped with a rubber duck antenna (3 dBi gain) showed that the RSSI is between -107 dB to -85 dB for the distance of up to 165 meter. Meanwhile, by the use of a Yagi antenna with the gain of 7.37 dBi, the RSSI value is between -100 dB to -80 dB. All of those results verify that LoRa is capable for the communication infrastructure of Polnes water management system.

Abstract— Electric power distribution system is one of the systems in electric power that has an important role that is directly related to the user of electric energy. In the distribution system must have the appropriate reliability of the standards applied but in reality the distribution of electric power distribution is not appropriate, such as falling voltage commonly called drop voltage that reaches the consumer. This is caused by several factors so that the quality of existing electricity is not optimally beneficial and can even cause damage to electrical equipment. In phase S, from the analysis of calculations and measurements made by the author based on basic theory, conclusions can be drawn as follows. In calculations and measurements in phaseS R and T the voltage fall is caused by the length of the delivery. In phase S, when viewed from the calculation and measurement of voltage fall due to the length of the delivery and other factors, namely the cable connection is not perfect. From the data obtained by the author of the voltage fall at the GNK 383 Distribution Substation is not constant because the load changes the use of electrical energy by different consumers The voltage fall at the GNK 383 Distribution Substation occurs at night because the load usage activity by consumers is very high.

Authors: Shah Dr. Jigna Sathya , Mathumathi Dr. A.
Published: June 2022

Background: Ameloblastoma is a rare odontogenic neoplasm of the mandible and maxilla, with multiple histologic variants, and high recurrence rates if improperly treated. Objective: To evaluate the various clinical and radiological behavior (2D & 2D) of histologically diagnosed ameloblastoma with or without impacted teeth. Materials and Methods: The present hospital-based retrospective study was conducted by reviewing the clinical and radiographic records of ameloblastoma cases from 2018 to 2021, available in the archives of the department. A total of 21 patients were analyzed were grouped into 1 and 2 on the basis of radiographic findings, ameloblastoma with impacted teeth and without impacted teeth. Results: We observed that the patients affected with ameloblastoma were in the age-group of 21–40 yrs. The male: female ratio was 1.5:1 in group 1 and 3:1 in group 2. The posterior mandible (70% in group 1 and 100% in group 2) was more commonly affected than the maxilla. Multilocular appearance was seen in 75% of group 2 and 10% of group 1 cases. Effect on adjacent teeth like displacement (70%), knife edge root resorption (70%) and loss of lamina dura (90%) were most commonly associated with group 1 compared to group 2. Conclusion: Ameloblastoma is usually benign tumors. Thorough history along with clinical examination and interpretation of radiographs are necessary to diagnosis this lesion accurately for early treatment and better prognosis.
Comparison of Conventional Rapid Palatal Expansion with Bone Anchored and Tooth-Bone Anchored Rapid Palatal Expansion Appliances
Authors: Trivedi Dr. Ipsit
Published: June 2022

In modern orthodontics, several types of designs for bone anchored expansion appliances have been developed with the objective to increase the amount of skeletal expansion with rapid palatal expansion. In the present review, the skeletal and dental effects of rapid palatal expansion have been evaluated immediately following expansion and in the long-standing interval following expansion. The effects of conventional rapid palatal expansion appliances are compared with bone anchored maxillary expansion appliances and tooth-bone anchored maxillary expansion appliances. Temporary Anchorage Devices (TADs), or mini-screws, or mini-implants are used for the insertion of bone anchored and tooth-bone anchored maxillary expansion appliances. These lead to higher forces on the bone while expansion is undertaken and consequently more orthopedic effects.

Published: June 2022

Gender equity and women’s empowerment are prerequisites to effective biodiversity conservation, climate action and meeting the Sustainable Development Goals. In view of its ecological, social, and economic value, wildlife is an important renewable natural resource. Its significance is felt in areas such as rural development, land-use planning, food supply, tourism, scientific research, and cultural heritage. A better understanding of the different roles, knowledge, needs and aspirations of women and men with regard to wildlife management and conservation can help us achieve the twin goals of better conservation outcomes and increased gender equity. This study aimed to assess the prevalence of men and women in wildlife management and conservation and sustainable community based conservancies within the Maasai Mara ecosystem, Narok County, Kenya with the aim of coming up with the best strategies to enhance gender-responsive and sustainable wildlife ecosystem. The study was carried out in four Maasai Mara wildlife conservancies. A descriptive survey and sequential explanatory mixed-method approach were adopted for the study. A sample size of 167 respondents comprising wildlife managers, conservancy, landowners, and conservancy rangers participated in the study. Data collection was done using questionnaires, Focused Group discussion and interviews. The data collected quantitatively was analysed using descriptive statistics and the findings were presented using percentages, graphs, and tables. The findings showed that there were gender differentials in prevalence of men and women in wildlife management and conservation in the Maasai Mara ecosystem. Women were underrepresented as staff, wildlife managers, and landowners in the conservancies. The study recommends that the wildlife conservancies, institutions, and managers should find ways of incorporating more women into wildlife management and conservation as well as employ gender advocacy and empowerment programmes to facilitate gender equity in wildlife ecosystems.

The methods of searching for source information for ships, infrastructure for them in various states (during design, construction and operation) are given. A brief assessment of the impact of various rules and regulatory documents on the ways of investing in small vessels is given. The article presents an original approach to solving a multi-criteria optimization problem, which consists in choosing a passenger ship (houseboat) project in combination with determining the preferences of the customer and other participants in the investment choice. The result of this study is a multi-criteria model of the decision-making situation under consideration. The formulation of the problem includes the interests of various stakeholders. The methodology is applied to real houseboat projects, includes an assessment by stakeholders of four key approaches to solving the problem and an algorithm capable of solving a complex joint selection task.
La relación causal entre la agravación del riesgo y la ocurrencia del siniestro en el seguro de daños
Authors: Mercadal Juan José Martínez
Published: June 2022

La ley uruguaya 19.678 regula en un único cuerpo normativo el contrato de seguros, huyendo de la codificación decimonónica, sin perjuicio de la vigencia de las normas especiales sobre seguros obligatorios y regulación de la actividad. Un nuevo y único cuerpo normativo que construye un subsistema de Derecho que deberá dialogar con el Derecho de Consumo, ambos con expresa declaración de orden público. En el presente trabajo procuramos ingresar en un aspecto que hace al diálogo del Derecho de Seguros con la teoría general de la responsabilidad civil (texto y contexto de los arts. 18 y 20 ley 19.678) y desentrañar el significado del art. 20 en cuanto a si es necesario exigirle al asegurador la prueba de la relación causal entre el hecho, omisión o comportamiento que se constituye en agravación del estado del riesgo y el acaecimiento del evento (siniestro) a efectos de permitir liberarlo de sus obligaciones.
Seguros de Responsabilidade Civil: uma necessidade social?
Authors: Polido Walter
Published: June 2022

Os seguros de responsabilidade civil têm papel significativo na sociedade pós-moderna, revestida de riscos, mas que são tolerados pelos diferentes usuários de produtos e serviços, em nome da plena satisfação pessoal, cujo anseio visa a “felicidade”. No campo do Direito, em face do giro conceitual de ato ilícito para dano injusto, os empresários e todos aqueles que exercem atividade profissional e econômica, estão, a cada dia, mais expostos a demandas objetivando indenizações por danos. Os seguros de responsabilidade civil representam, neste cenário, mecanismo financeiro eficaz de proteção patrimonial, mantendo indene os causadores de danos, além de oferecerem a garantia objetiva, aos prejudicados, de que serão indenizados. Vários são os modelos oferecidos pelo mercado de seguros, cada qual com as suas especificidades técnico-jurídicas aplicáveis. Este texto interliga todas essas vertentes.

Cacopsylla burckhardti Luo, Li, Ma & Cai, 2012 (Hemiptera, Psylloidea, Psyllidae) is a pear psyllid species, distributed in the East Asia. The complete mitogenome of C. burckhardti is obtained in this study for the first time. The mitogenome of C. burckhardti is circular form and 14,798 bp long, which consists of 13 protein-coding genes, 22 tRNAs and two rRNAs. The base composition is 38.80% for A, 34.89% for T, 9.99% for G and 16.33% for C, with the higher A + T contents (73.69%). The phylogenetic analysis, using 13 protein-coding genes, shows that C. burckhardti is clustered with other Cacopsylla species and nested in the Psyllidae clade within the superfamily Psylloidea.
Die Bekrönung der Tempel im hellenistisch-römischen Syrien. Neue Überlegungen zu den Zinnen im Belheiligtum von Palmyra
Authors: Schmidt-Colinet Andreas , Seigne Jacques
Published: June 2022

Le couronnement des bâtiments avec une rangée des merlons (crénelure) peut être suivi depuis l’architecture sacrée et impériale du Proche-Orient ancien jusqu’au début de l’architecture islamique. Dans ce cadre géographique et chronologique de distribution de ce motif architectural, les bâtiments de Palmyre occupent une position centrale. L’article examine les merlons trouvés dans le sanctuaire de Bêl à Palmyre. Il apporte des arguments pour réviser la reconstitution proposée jusqu’à présent, en ce qui concerne les merlons surmontant les longs côtés du temple de Bêl et les merlons d’angle au sommet des tours de la cella du temple.
Un système de captage hydrique rare en Alsace : le qânat de Kolbsheim (Bas-Rhin)
Authors: Daverat Loïc , Goepfert Sébastien
Published: June 2022

La fouille du site de Kolbsheim Herrenweg (Bas-Rhin, Alsace) a permis de documenter un dispositif atypique de captage d’eau, dont un seul exemple était connu jusqu’alors en Alsace : un qânat . Ce système repose sur un conduit en pierre sèche creusé à une profondeur d’environ 4 à 5 m, grâce à une succession linéaire d’une vingtaine de puits régulièrement espacés. L’exutoire de cet ouvrage daté du Haut-Empire se situe vraisemblablement à quelques centaines de mètres à l’est de la zone de fouille, sur la commune de Breuschwickersheim, où une prospection pédestre a permis de localiser un établissement rural antique.
Les boucles de rétroaction au sein des interdépendances. Le cas des infrastructures d’eau potable
Authors: Caillaud Kevin
Published: June 2022

De par leur dimension historique et leurs caractéristiques sociotechniques (dont une fonction relationnelle établie entre ressources, territoires, services et populations), les infrastructures d’eau potable apparaissent comme des révélateurs des interdépendances auxquelles sont confrontés les services publics. Ces interdépendances – entendues comme des relations mutuelles entre les éléments constitutifs du système d’eau potable produisant des effets de réciprocité – se nichent au sein et à la croisée de différentes dimensions liées au fonctionnement des services publics et impliquant la question infrastructurelle : l’environnement, l’appareillage technique, l’organisation politico-administrative, l’aménagement territorial, la demande et les usages de l’eau, etc. Elles mettent en scène une confrontation des registres de représentation et d’action sur le système d’eau, et les interactions qui en découlent. Ces relations d’interdépendance se traduisent par des boucles de rétroaction ayant pour conséquence d’agir sur le positionnement des acteurs, et pour résultat de recomposer les enjeux, les rapports de force et les actions. L’enfermement des acteurs dans une approche segmentée des problèmes empêche ainsi d’appréhender le secteur dans sa globalité et d’anticiper l’imbrication des différents éléments problématiques. L’article vise ainsi à contribuer à l’analyse sociohistorique et cognitive des services et des infrastructures d’eau potable, en les repositionnant dans une perspective holistique non linéaire.

Peindre « le visage de la guerre » : la place du paysage dans l’œuvre dorgelèsienne consacrée à la Grande Guerre
Authors: Sauvage Juliette , Sauvage Juliette
Published: June 2022

Roland Dorgelès, avare en descriptions et en arrêts sur image, écrit tantôt une guerre de bruit et de mouvement, tantôt une guerre silencieuse et imperceptible. Ce n’est qu’à travers le regard singulier du soldat que celle-ci peut prendre vie. De vacances bucoliques en visions d’enfer, l’écrivain-combattant peint une multitude de représentations a priori paradoxales des paysages de guerre qui, toutes réunies, composent pourtant le saisissant « visage » de la Grande Guerre.
