An Inverse Class-E Power Amplifier for Ultrasound Transducer
Authors: Choi Hojong
Published: March 2023

An inverse Class-E power amplifier was designed for an ultrasound transducer. The proposed inverse Class-E power amplifier can be useful because of the low series inductance values used in the output matching network that helps to reduce signal distortions. Therefore, a newly designed Class-E power amplifier can obtain a proper echo signal quality. The measured output voltage, voltage gain, voltage gain difference, and power efficiency were 50.1 V, 22.871 dB, 0.932 dB, and 55.342%, respectively. This low voltage difference and relatively high efficiency could verify the capability of the ultrasound transducer. The pulse-echo response experiment using an ultrasound transducer was performed to verify the capability of the proposed inverse Class-E power amplifier. The obtained echo signal amplitude and pulse width were 6.01 mVp-p and 0.81 μs, respectively. The −6 dB bandwidth and center frequencies of the echo signal were 27.25 and 9.82 MHz, respectively. Consequently, the designed Class-E power amplifier did not significantly alter the performance of the center frequency of the ultrasound transducer; therefore, it could be employed particularly in certain ultrasound applications that require high linearity and reasonable power efficiency.

In today’s digitalized era, the world wide web services are a vital aspect of each individual’s daily life and are accessible to the users via uniform resource locators (URLs). Cybercriminals constantly adapt to new security technologies and use URLs to exploit vulnerabilities for illicit benefits such as stealing users’ personal and sensitive data, which can lead to financial loss, discredit, ransomware, or the spread of malicious infections and catastrophic cyber-attacks such as phishing attacks. Phishing attacks are being recognized as the leading source of data breaches and the most prevalent deceitful scam of cyber-attacks. Artificial intelligence (AI)-based techniques such as machine learning (ML) and deep learning (DL) have proven to be infallible in detecting phishing attacks. Nevertheless, sequential ML can be time intensive and not highly efficient in real-time detection. It can also be incapable of handling vast amounts of data. However, utilizing parallel computing techniques in ML can help build precise, robust, and effective models for detecting phishing attacks with less computation time. Therefore, in this proposed study, we utilized various multiprocessing and multithreading techniques in Python to train ML and DL models. The dataset used comprised 54 K records for training and 12 K for testing. Five experiments were carried out, the first one based on sequential execution followed by the next four based on parallel execution techniques (threading using Python parallel backend, threading using Python parallel backend and number of jobs, threading manually, and multiprocessing using Python parallel backend). Four models, namely, random forest (RF), naïve bayes (NB), convolutional neural network (CNN), and long short-term memory (LSTM) were deployed to carry out the experiments. Overall, the experiments yielded excellent results and speedup. Lastly, to consolidate, a comprehensive comparative analysis was performed.
Traffic Breakdown Probability Estimation for Mixed Flow of Autonomous Vehicles and Human Driven Vehicles

Published: March 2023

Automated vehicles are expected to greatly boost traffic efficiency. However, how to estimate traffic breakdown probability for the mixed flow of autonomous vehicles and human driven vehicles around ramping areas remains to be answered. In this paper, we propose a stochastic temporal queueing model to reliably depict the queue dynamics of mixed traffic flow at ramping bottlenecks. The new model is a specified Newell’s car-following model that allows two kinds of vehicle velocities and first-in-first-out (FIFO) queueing behaviors. The jam queue join time is supposed to be a random variable for human driven vehicles but a constant for automated vehicles. Different from many known models, we check the occurrence of significant velocity drop along the road instead of examining the duration of the simulated jam queue so as to avoid drawing the wrong conclusions of traffic breakdown. Monte Carlo simulation results show that the generated breakdown probability curves for pure human driven vehicles agree well with empirical observations. Having noticed that various driving strategy of automated vehicles exist, we carry out further analysis to show that the chosen car-following strategy of automated vehicles characterizes the breakdown probabilities. Further tests indicate that when the penetration rate of automated vehicles is larger than 20%, the traffic breakdown probability curve of the mixed traffic will be noticeably shifted rightward, if an appropriate car-following strategy is applied. This indicates the potential benefit of automated vehicles in improving traffic efficiency.

Published: March 2023

Fog Computing (FC) was introduced to offer resources closer to the users. Researchers propose different solutions to make FC mature and use simulators for evaluating their solutions at early stages. In this paper, we compare different FC simulators based on their technical and non-technical characteristics. In addition, a practical comparison is conducted to compare the three main FC simulators based on their performance such as execution time, CPU, and memory usage for running different applications. The analysis can be helpful for researchers to select the appropriate simulator and platform to evaluate their solutions on different use cases. Furthermore, open issues and challenges for FC simulators are discussed that require attention and need to be addressed in the future.

Published: March 2023

The use of antibiotics following oral poisoning by corrosives and organophosphates is controversial. We assessed the clinical outcomes of using antibiotics in acute poisonous ingestion involving corrosives or organophosphates by conducting a retrospective cohort study of patients presenting to the emergency department following ingestion of corrosives or organophosphates who received either antibiotics or supportive care. The endpoints included clinical stability, length of stay (LOS), and mortality. Of 95 patients, 40 received antibiotics and 55 received supportive care. The median age was 2.1 and 2.7 years, respectively (p = 0.053). Bacterial growth was shown in only 2 of 28 cultures (both were respiratory), but with hospital-acquired organisms as it was shown ≥4 days post-admission. Clinical stability rates were 60% and 89.1% in the antibiotic and supportive care groups, respectively (p < 0.001). Median LOS was 3 vs. 0 days (p < 0.001), and no mortality was recorded. NG/G-tube placement was the only factor associated with clinical failure (OR, 20.97; 95% CI, 2.36–186.13). Antibiotic use was not associated with higher chances of clinical stability, which may suggest that their use was unnecessary. Clinicians are encouraged to use antibiotics wisely, and only in the presence of a clear indication of an infection. This study provides a basis for future prospective studies to confirm its findings.

Published: March 2023

In the literature, there was inconsistency in the risk of malaria between individuals with Rhesus blood group positive (Rh+) and negative (Rh−). The systematic review aimed to investigate the risk of malaria among participants with different Rh blood types. All observational studies that reported the occurrence of Plasmodium infection and investigation of the Rh blood group were searched in five databases (Scopus, EMBASE, MEDLINE, PubMed, and Ovid). Strengthening the Reporting of Observational Studies in Epidemiology was used to assess the reporting quality in the included studies. A random-effects model was used to calculate the pooled log OR and 95% confidence intervals (CIs). Database searches yielded a total of 879 articles, of which 36 were eligible for inclusion in the systematic review. The majority of the included studies (44.4%) revealed that Rh+ individuals had a lower proportion of malaria than Rh− individuals; however, the remaining studies revealed a higher or no difference in the proportion of malaria between Rh+ and Rh− individuals. Overall, with moderate heterogeneity, the pooled results showed no difference in malaria risk between patients with Rh+ and Rh− (p = 0.85, pooled log OR: 0.02, 95% CI: −0.20–0.25, I2: 65.1%, 32 studies). The current study found no link between the Rh blood group and malaria, even though there was a moderate amount of heterogeneity. Further studies using prospective designs and a definitive method for Plasmodium identification are needed to investigate the risk of Plasmodium infection in Rh+ individuals and increase the reliability and quality of these studies.

Published: March 2023

Background: COVID-19 is a significant public health problem that can have a negative impact, especially in vulnerable regions. Objective: This study aimed to provide evidence that could positively influence coping with COVID-19 based on the relationship between the potential epidemic vulnerability index (PEVI) and socioepidemiological variables. This could be used as a decision-making tool for the planning of preventive initiatives in regions with relevant vulnerability indices for the spread of SARS-CoV-2. Methodology: We performed a cross-sectional study, with the analysis of the population characteristics of COVID-19 cases associated with neighborhoods’ PEVIs in the conurbation region of Crajubar, northeastern Brazil, through the mapping of socioeconomic–demographic factors and spatial autocorrelation. Results: The PEVI distribution indicated low vulnerability in areas with high real estate and commercial value; as communities moved away from these areas, the vulnerability levels increased. As for the number of cases, three of the five neighborhoods with a high–high autocorrelation, and some other neighborhoods showed a bivariate spatial correlation with a low–low PEVI but also high–low with indicators that make up the PEVI, representing areas that could be protected by public health measures to prevent increases in COVID-19 cases. Conclusions: The impact of the PEVI revealed areas that could be targeted by public policies to decrease the occurrence of COVID-19.

Published: March 2023

Reduction or suppression of microphonic interference in radio frequency (RF) cavities, such as those used in Electron Linear Accelerators, is necessary to precisely control accelerating fields. In this paper, we investigate modeling the cavity as a cylindrical shell and present its free vibration analysis along with an appropriate control scheme to suppress vibrations. To this end, we first obtain an analytical mechanical dynamic model of a nine-cell cavity using a modified Fourier-Ritz method that provides a unified solution for cylindrical shell systems with general boundary conditions. The model is then verified using the ANSYS software in terms of a comparison of eigenfrequencies which prove to be identical to the proposed model. We also present an active observer-based vibration control scheme to suppress the dominant mechanical modes of the cavity. The control system performance is investigated using simulations.

Published: March 2023

Low temperatures induce limited charging ability and lifespan in lithium-ion batteries, and may even cause accidents. Therefore, a reliable preheating strategy is needed to address this issue. This study proposes a low-temperature preheating strategy based on neural network PID control, considering temperature increase rate and consistency. In this strategy, electrothermal films are placed between cells for preheating; battery module areas are differentiated according to the convective heat transfer rate; a controller regulates heating power to control the maximum temperature difference during the preheating process; and a co-simulation model is established to verify the proposed warm-up strategy. The numerical calculation results indicate that the battery module can be preheated to the target temperature under different ambient temperatures and control targets. The coupling relationship between the preheating time and the maximum temperature difference during the preheating process is studied and multi-objective optimization is carried out based on the temperature increase rate and thermal uniformity. The optimal preheating strategy is proven to ensure the temperature increase rate and effectively suppress temperature inconsistency of the module during the preheating process. Although preheating time is extended by 17%, the temperature difference remains within the safety threshold, and the maximum temperature difference is reduced by 49.6%.

Published: March 2023

In one of our previous articles, we presented our own vision of improving the system of valuation objects in accounting and reporting, thus proposing a new system of these objects. In continuation of our ideas in this article, we will make recommendations regarding the modernization of the chart of accounts of accounting, based on the system of the above-mentioned objects proposed by us (including for healthcare organizations). Note that the new system of valuation objects (which in the previous article we called accounting objects and elements of financial statements) certainly requires significant changes in the system of accounts used to account for valuation objects. Proposals for these changes are presented by us in this article. When conducting research, such methods as analysis and synthesis, comparison, grouping method, analogy method, logical approach, systematic approach were used. As a result of the research, this article proposes a modernized chart of accounts (including for healthcare organizations), which meets the requirements of modern times. The results presented in this paper will be useful to a wide range of readers interested in the problems of Russian accounting, including the valuation of its objects and the formation of a chart of accounts, and can also be used in the educational process of higher educational institutions, in the practical work of organizations (in particular, healthcare) and in development and improvement of relevant regulatory documents on accounting.

Published: March 2023

The article reports the results of studies of zooplankton communities сonducted in 2017–2020 in some rivers of the Podkamennaya Tunguska river catchment. Zooplankton samples were selected and processed according to generally accepted methods. The taxonomic composition was determined for the first time (except for the Kamo River). The taxonomic composition included 48 taxa: Rotifera — 21, Cladocera — 16, Copepoda — 13. The greatest species diversity of zooplankton was recorded in the Tohomo, Tetere and Taiga rivers — 18–26 taxa, the smallest — in the Ter, Levoe Cheremo and Levaya Tokura rivers — one species each. In most rivers there were rotifers Euchlanis dilatata, and crustaceans — Acroperus harpae, Chydorus sphaericus. In general, rotifers and cladocerans played a significant role in the zooplankton of the studied rivers. The average abundance and biomass of zooplankton organisms varied from 22 to 2673 ind./m3 and from 0.001 to 29.63 mg/m3, respectively. Zooplankton was most developed in the Tetere river due to the abundance of large cladoceras of the genus Alona, Daphnia longispina, Eurycercus lamellatus, Simocephalus vetulus. Low the average abundance was in the rivers Maliy Yurubchen, Levaya Tokura, biomass — Verhvnya Madra, Dugungna, Maliy Yurubchen, Yurubchen, Tes, Levoe Cheremo, Levaya Tokura characterized by a relatively high flow rate and limited supply of organic and biogenic substances that determine the development of the invertebrate food supply. According to the quantitative characteristics of zooplankton, the rivers of the Podkamennaya Tunguska river catchment are characterized as poor in feed.

The nutrition of sunbleak (Leucaspius delineatus) from the pond of Noginsk district of Moscow region in February 2023, owned by GNP “Yakor”, was studied. The aim of the study was to investigate the nutrition of sunbleak. To achieve this aim, the following tasks were performed: the age of the caught fish, their average length and weight were determined, the quantitative and qualitative composition of zooplankton in the reservoir was studied, the food boluses of the fish were considered in order to establish the frequency of occurrence of food objects in them, the intestinal filling index and the selection index. The study of the sunbleak nutrition seems relevant for establishing links in the ecosystem of a fishery reservoir, with the aim of further optimal selection of fish multiculture, based on the analysis of the state of the natural food supply. As part of the zooplankton community of the reservoir, 11 taxa were identified: 4 species of rotifers, 4 species of branchous and 3 taxa of copepods. In the course of the study, it was found that the sunbleak from the reservoir in question fed on almost all the species encountered except rotifers. With age, the fullness of the fish intestines decreased. The species composition of the consumed crustaceans differed depending on the age of the fish. Younger fish preferred the smaller size species of crustaceans, older fish preferred larger size and more nutritious species of crustaceans. Crustaceans of the Daphnia genus turned out to be the most preferable food for the sunbleak of all ages, and with age, the fish more and more preferred this food object. The most abundant crustaceans of the Bosmina genus in the water body were avoided by the fish, even the underyearlings, the only age category of the sunbleak that fed on these organisms.

An overview of typical lakes of the floodplain system of the river is presented. Ob in the lower reaches of the Novosibirsk hydroelectric power station, data on the species structure and biomass of fish, zoobenthos and zooplankton are presented. Most lakes of the Ob floodplain have an elongated channel-like shape and have a constant hydrological connection with the channels of the Ob River. The area of the lakes does not exceed 40 hectares. According to the research results, the zooplankton of the lakes is represented by 20 species, the total number of zooplankton varied from 50 620 copies/m3 (Kolkhoznoye lake) to 477 740 copies/m3 (Bolshoy Elbak lake). The biomass of zooplankton in the surveyed lakes was 2488–3443 mg/ m3. 24 species were found in the zoobenthos of floodplain lakes, the total number of zoobenthos varied from 887 copies/m2 (Kolkhoznoye lake) to 3468 copies/m2 (Bolshoy Elbak Lake). The biomass of zoobenthos varied from 3,100 to 38,152 g/m2. According to the indicators of zooplankton biomass, lakes are characterized as reservoirs of beta-mesotrophic type, i.e. of the middle productivity class, according to the classification of feeding capacity — as reservoirs above the average feeding capacity for planktophagous fish. On the development of zoobenthos lake. Vilannoe refers to high–fed, eutrophic type reservoirs, high productivity class, Kolkhoznoye lake — to medium-fed, mesotrophic type reservoirs, moderate productivity class, Bolshoy Elbak lake refers to high-fed reservoirs of mesotrophic type of medium productivity class. The main species of ichthyofauna of floodplain lakes are the firebrand rotan (Perccottus glenii) and silver carp (Carassius gibelio). The biomass of the ichthyofauna is 45.1–100.9 kg/ha. As a result of the study, it was revealed that commercial development of the ichthyofauna of these lakes is impractical, but their use for commercial fish farming is possible.

Authors: Cowen Clare , Frinsco Shelley , Nosal Rebecca , Colen Faith
Published: March 2023

BACKGROUND: From August 2018 to January 2019, the baseline urine sample contamination rate at an acute care hospital emergency department (ED) was 51%. Urine culture contamination is associated with unnecessary antibiotic use, repeat culture costs, and unnecessary inpatient admissions. These outcomes can lead to additional cost to the patient and healthcare system while leading to additional poor outcomes.

METHODS: Culture results were reviewed and the project definition of contamination was applied. Contaminated cultures were reviewed further via manual electronic health record review of ED notes to determine documentation of collection source, education prior to clean catch collection, the cognitive and physical documented descriptions of the patient, and the name of the staff member who collected the sample.

INTERVENTION: Staff were educated on appropriate midstream and straight catheter collection techniques, verbal along with picture education for patients, and appropriate identification of patients who may benefit from straight catheterization instead of clean catch.

RESULTS: The combined interventions resulted in a six-month decrease of contaminated urine samples from the initial 51% to <10%, resulting in an 80% decrease.
CONCLUSION: Urine culture contamination in an acute care ED was sustainably decreased through multiple process improvement interventions. Secondary outcomes included reduction in unnecessary antibiotic use, repeat urine cultures, and unnecessary admissions.

This study examines the suitability of the managerial model (the strategy, support and competence of managers) on the successful use of financial applications for insurance companies registered with the Indonesian Financial Services Authority (OJK). Quantitative methods used to confirm the proposed model and predict the magnitude of the influence that arises between the variables studied. Primary data was collected by distributing questionnaires to 313 accounting and finance managers of insurance companies registered OJK Indonesia and 160 sample sizes were collected through a simple random technique. Data analysis used Covarian Base Structural Equation Model (CB-SEM) with Lisrell 8.5 software. The results of this study have succeeded in confirming the conceptual model developed by researcher and proving that managerial model variables have an effect on the successful use of financial applications in insurance companies registered OJK Indonesia. This research proves that the successful of using financial application depends on the relevance of the user. The Managerial Model shows that the right management strategy and top management support as well as adequate managerial competence effectively make the system more flexible, integrated, easy to access which in turn creates user satisfaction and intensive use of the system in an organization. The successful use of applications in an organization encourages the company's operational activities to run effectively and efficiently and to achieve competitive advantage

Le statut servile au «premier âge féodal ». Réflexions et questions
Authors: Barthélemy Dominique
Published: March 2023

Avec un regard renouvelé par l’anthropologie, on peut apercevoir dans les chartes françaises du XIe siècle toute une vie publique imprégnée de normes juridiques, même si ces dernières sont flexibles. La relation entre un seigneur et son serf est fixée et débattue devant une communauté sociale plus ou moins large. Nul juridisme ne vient empêcher les improvisations habiles, le bricolage avisé. Jamais, semble-t-il, la documentation ne nous propose une gamme aussi étendue des résonances et des usages possibles d’un statut servile. Un servage, ritualisé, est un signe fort : il évoque l’appartenance, l’obéissance, l’humiliation ; mais il se combine toujours à d’autres marques de statut, les unes allant dans le même sens que lui (marques de sujétion), les autres en sens inverse (chevalerie et même noblesse). Il n’a donc pas la même portée pour un noble qui fait pénitence et pour un paysan qui s’enrôle.
Conquêtes et reconquêtes médiévales : la Sicile normande est-elle une terre de réduction en servitude généralisée?
Authors: Nef Annliese
Published: March 2023

L’évolution des statuts paysans du VIe au XIIe siècle en Sicile est mal connue et on ne dispose de données qu’après la conquête normande. Les Arabo-musulmans ont-ils été soumis à une réduction en servitude que leur confession pouvait justifier ? La question a souvent été analysée à travers les catégories détaillées dans les Assises d’Ariano, mais les passages concernés semblent postérieurs au XIIe siècle. En outre, les vocables latins, grecs et arabes livrés par les documents sont difficilement superposables. Une analyse lexicale renouvelée permet d’avancer des hypothèses renforcées par les données contenues dans les actes étudiés : l’attachement à la terre de paysans dont les statuts, variés, sont marqués par une continuité forte avec la période antérieure, apparaît tardive et se heurte à leur résistance.
Declino e rilancio della servitù : tra teoria e pratica giuridica
Authors: Conte Emanuele
Published: March 2023

L’idea che le dottrine giuridiche dei giuristi medievali non abbiano avuto alcuna rilevanza nella determinazione delle condizioni personali dei dipendenti rurali è relativamente recente. Ancora nel XVIII secolo Christian Thomasius riconosceva ai iuris professores di aver svolto un ruolo nell’affrancazione dei servi della gleba tedeschi. L’astrazione giuridica aveva in effetti elaborato strumenti argomentativi efficaci sia per affermare la libertà dei rustici dipendenti sia per tutelare i diritti dei signori a riceverne le prestazioni. La lettura parallela di un consilium di Iacopo Balduini e di una Summula di Azzone consente di rilevare che la legislazione giustinianea sul colonato è utilizzata dai glossatori per escludere che i rustici medievali possano esser considerati veri e propri coloni. Più complessa la dialettica fra gli argomenti contrapposti quando è in discussione l’obbligazione a prestare i servizi servili e il corrispettivo diritto del signore a riceverli. La dottrina e la pratica finiranno per assimilare questi obblighi ai diritti reali.
Villanus au XIIIe siècle dans la documentation siennoise
Authors: Redon Odile
Published: March 2023

Le mot villanus apparaît dans la documentation siennoise à la fin du XIIe siècle, impliquant la dépendance d’un homme vis-à-vis d’un seigneur : dépendance réelle, fondée sur la disposition d’un tenure, et personnelle, transmise héréditairement comme la tenue. Le «vilain» doit à son seigneur des services (gîte, corvée), des aides, des redevances ; sa liberté de quitter la tenure est limitée. Les conflits quit s’élèvent à ce sujet suscitent une vaste production documentaire, dans le registre législatif au niveau de la Commune urbaine et dans le registre judiciaire. Par contre, le terme de villanus est absent des chartes de franchise, des statuts ruraux et des autres documents impliquant des communes rurales. Il semble donc que le mot «vilain» ait un sens précis dans la relation entre seigneur et dépendants et que ce sens soit discuté dans le droit ; mais l’acception péjorative, qui est ensuite passée du latin aux langues romanes, le rendait inutilisable là où déjà les travailleurs de la terre s’affirmaient comme membres de communautés politiquement organisées.
Les homines de mansata en Bas-Languedoc (milieu du XIIe – milieu du XIVe siècle) : théorie, pratiques et résistances
Authors: Bourin Monique
Published: March 2023

Le Bas-Languedoc n’a pas la réputation d’être terre de servitude. Si tel est le cas dans la région de Montpellier et plus à l’est, il en va autrement plus à l’ouest, mais la situation y est nuancée. Au XIIe siècle, rien dans le vocabulaire et les clauses ne semble distinguer une dépendance honorable d’autres formes de dépendance. À partir de la fin du XIIe siècle, la servitude y prend partout une forme réelle, définie comme un statut plus net ; le serfs sont dits homines de mansata. Les traces sont faibles dans la partie centrale où peu à peu le régime de l’emphytéose s’impose aux tenures serviles. Plus à l’ouest, la pression seigneuriale est plus nette, s’accentuant sans doute au XIVe siècle, mais c’est autour d’une restriction au droit de propriété, notamment au droit de transmettre en ligne indirecte que finit par s’organiser le statut et les conflits qu’il génère.
Conclusion
Authors: Bourin Monique , Freedman Paul
Published: March 2023

Dans le monde méditerranéen, l’évolution de la servitude est plus homogène qu’on ne pouvait le croire, même s’il est des cas où elle ne s’est jamais vraiment développée. Elle n’est pas un reliquat d’une période antérieure : les entrées en servitude se poursuivent pendant toute cette époque. La servitude est caractérisée partout au XIIe siècle par une phase de dépendance floue. Les devoirs et les services des serfs ne sont pas spécifiques de ce statut. Les mots mêmes sont ambigus : le serf est en général seulement dit homo, et les documents n’enregistrent pas le statut avec rigueur. La phase d’institutionnalisation vient ensuite, ce qui ne signifie pas alourdissement des perceptions. Les corvées ne sont nullement alors la caractéristique principale de ce statut, mais plutôt le contrôle de la possession des tenures, en forme de manse et de casal. Dans cette évolution, l’influence du droit savant est ambivalente, comme d’ailleurs la politique des villes.
Note sur le vocabulaire de la servitude et de l’esclavage en Toscane à la fin du Moyen Âge
Authors: Delort Robert
Published: March 2023

Il est très difficile de distinguer, d’après le seul vocabulaire, dans les documents des XIVe et XVe siècles, en latin comme en toscan, esclaves et serviteurs (libres). L’esclave mâle est dit sclavus, mancipium et la femme ancilla, sclava mais la formule courante est sclavus et servus, ou serva vel ancilla. Or la littérature de Dante à Machiavel, à côté de rarissimes schiavi, schiave connaît des servi, serve qui peuvent être des serviteurs (embauchés) autant que des esclaves (achetés ou capturés). Le droit romain (statut du servus) et la situation très dépendante des serviteurs (libres, que la fonction voire la situation apparente étroitement à celle des esclaves domestiques, amènent cette ambiguïté, parfois impossible à lever, dont il faut tenir compte dans les traductions et les interprétations.
