Résumé Il semble difficile de structurer la formation des traducteurs dans la perspective d’une pédagogie par objectifs, dans la mesure où cela supposerait que l’activité traduisante peut être analysée comme étant la mise en oeuvre d’un faisceau de compétences partielles ; alors qu’on est sans doute fondé à penser que la compétence traductive correspond à une pratique globale, holiste, et qu’il conviendra donc de mettre en place une formation fondamentale polyvalente et générative. Il reste qu’il y a lieu de faire l’inventaire des divers éléments de formation qui concourent à définir le cursus au terme duquel on aura formé un traducteur professionnel. Dans ce cadre, il se trouve que, très paradoxalement, la traduction philosophique peut apporter une contribution spécifique à la formation des traducteurs professionnels.

Résumé À rencontre des discours, aujourd'hui dominants, qui postulent une correspondance linéaire entre la technique, les impératifs économiques et les savoirs, cette étude entend montrer comment les institutions de formation retraduisent les demandes qui leur sont adressées selon une logique propre. Parmi ces processus de retraduction, l'action des enseignants s'avère en ce moment un opérateur essentiel de l'évolution de la formation professionnelle en France, laquelle tend à passer d'un apprentissage de savoirs de métier à un enseignement de savoirs techniques. En appréhendant les savoirs transmis par l'école comme le produit d'un faisceau de relations sociales, la démarche mise en œuvre ici permet de procéder à une analyse qui échappe aux conceptions sustantialistes et relativistas.

ABSTRACT We present constraints on the emergence and evolution of passive galaxies with the empirical model emerge, which reproduces the evolution of stellar mass functions (SMFs), specific and cosmic star formation rates since $z$ ≈ 10, ‘quenched’ galaxy fractions, and correlation functions. At fixed halo mass, present-day passive galaxies are more massive than active galaxies, whereas at fixed stellar mass passive galaxies populate more massive haloes in agreement with observations. This effect naturally results from the shape and scatter of the stellar-to-halo mass relation. The stellar mass assembly of present-day passive galaxies is dominated by ‘in situ’ star formation below ∼3 × 1011 M⊙ and by merging and accretion of ‘ex situ’ formed stars at higher mass. The mass dependence is in tension with current cosmological simulations. Lower mass passive galaxies show extended star formation towards low redshift in agreement with IFU surveys. All passive galaxies have main progenitors on the ‘main sequence of star formation’ with the ‘red sequence’ appearing at $z$ ≈ 2. Above this redshift, over 95 per cent of the progenitors of passive galaxies are active. More than 90 per cent of $z$ ≈ 2 ‘main sequence’ galaxies with m* > 1010 M⊙ evolve into present-day passive galaxies. Above redshift 6, more than 80 per cent of the observed SMFs above 109 M⊙ can be accounted for by progenitors of passive galaxies with m* > 1010 M⊙. This implies that high-redshift observations mainly probe the birth of present-day passive galaxies. emerge is available at github.com/bmoster/emerge.

Abstract The present study provides a synchronic morphophonological analysis of the passive verbal stems in Syriac. As is well known, Syriac passive stems are directly derived from their corresponding active stems by addition of the preformative ’et- and ablaut (vowel mutation). Oddly enough, ablaut always involves the final-stem vowel but never the first one, e.g. pa “el > ’etpa “al. We aim to show that the concept of Prosodic Circumscription developed by John McCarthy and his colleagues explains not only the asymmetry between the two vowels but also how the various internal modes of formation (gemination, infixation, ablaut) are distributed within the syllabic structure of the patterns, both active and passive.

Direct numerical simulation is used to study the mixing of a passive scalar by a vortex ring issuing from a nozzle into stationary fluid. The ‘formation number’ (Gharibet al. J. Fluid Mech.vol. 360, 1998, p. 121), is found to be 3.6. Simulations are performed for a range of stroke ratios (ratio of stroke length to nozzle exit diameter) encompassing the formation number, and the effect of stroke ratio on entrainment and mixing is examined. When the stroke ratio is greater than the formation number, the resulting vortex ring with trailing column of fluid is shown to be less effective at mixing and entrainment. As the ring forms, ambient fluid is entrained radially into the ring from the region outside the nozzle exit. This entrainment stops once the ring forms, and is absent in the trailing column. The rate of change of scalar-containing fluid is found to depend linearly on stroke ratio until the formation number is reached, and falls below the linear curve for stroke ratios greater than the formation number. This behaviour is explained by considering the entrainment to be a combination of that due to the leading vortex ring and that due to the trailing column. For stroke ratios less than the formation number, the trailing column is absent, and the size of the vortex ring increases with stroke ratio, resulting in increased mixing. For stroke ratios above the formation number, the leading vortex ring remains the same, and the length of the trailing column increases with stroke ratio. The overall entrainment decreases as a result.

Phosphonate layer formation on passive iron surface has been investigated by electrochemical and atomic force microscopy techniques. It was found that phosphonate groups bond more strongly to oxide surface, while metallic iron surface is disadvantageous for phosphonate layer formation in aqueous solutions. The rate of anodic dissolution is continually decreasing due to the time-dependent formation of protective phosphonate layer. The kinetics of phosphonate layer formation on passive iron is determined by the potential applied for preceding passive film formation. The size and shape of iron oxide grains depends slightly on the potential of passivation. Changes in morphology due to the phosphonate layer formation have been recorded by AFM.

Corrosion is one of the causes of failure in reinforced concrete structures, and forming a passive film on the steel is essential for protection. Although several studies have looked at passive film formation in concrete pore solutions, few have considered its formation in hardened concrete and the influence of silica fume (SF) in the binder composition. This study aims to evaluate the influence of the SF content on passive film formation time in concrete. Periodic measurements assessed the electrical resistivity and corrosion current density of concrete samples containing 5%, 10%, 15%, and 20% SF. The alkalinity of the mixtures and the kinetics of the pozzolanic reaction were also monitored by XRD and titration tests. The control mixtures exhibited susceptibility to corrosion, regardless of the curing age evaluated. In contrast, the partial replacement of cement with SF accelerated the formation of the passive film on the steel surface, suggesting a delayed onset of corrosion due to modifications in the physical properties of the concrete. Also, the portlandite content and pH can predict passive film formation, with SF significantly accelerating this process.

The electrochemical formation and characteristics of passive films on niobium surfaces in aqueous H2SO4 solutions were studied using open circuit potential and cyclic voltammetry. In the potential region between -1.0 and 1.2 V(NHE), the cyclic voltammetry data showed that the active/passive transition involves slow metal dissolution followed by the formation of semiconducting passive oxide films. The possible electrochemical reactions and the change of the oxidation steps of some niobium oxides occurring in the passive film during the polarization are proposed. A strong influence of the natural air-formed oxide film on the chemical composition of the passive film was shown. This influence makes chemical structure of thin passive films more complicated than that of thick anodic films. It is shown that the passive films consists of more or less stable oxides, such as NbO, NbO2 and Nb2O5. The Raman spectra revealed that the thin passive films were amorphous, while the films formed at higher voltages consist, primarily, of well-crystallized Nb2O5.

In order to maintain the formation, the position of Drones cluster can be adjusted by the method of azimuth-only passive positioning. In this paper, the circular formation is taken as an example. Firstly, when the coordinate information of Drones at the center of the circle and around the circle is known, the coordinates of other Drones are solved according to the Angle signal. By using polar coordinate programming, the Angle between different Drone lines is calculated, and using this information as known information, the nonlinear equations are solved by inverse derivation of their own coordinates. Secondly, in order to determine that at least several Drones need to transmit signals to realize effective positioning of all Drones in the circular formation, this paper concludes that only three Drones at most are needed to realize azimuth-only passive positioning based on the established model.

Nepali verb stems end with i, a, o and ʌ vowels, and voiced and voiceless consonants. From transitivity perspective, they are intransitive and transitive/ditransitive. The verbs are monosyllabic and polysyllabic from syllabicity point of view. Another feature that Nepali verbs have is sound [a] whose presence and absence has direct impact on causative stem formation. The causative stem formation is regular with some phonological restrictions; however, the passive stem formation is very productive. Negativization occurs from both prefixation and suffixation processes. On the basis of features and morphological processes, four types of stems, namely, base stem, passive stem, causative stem and causative passive stem are found.

GPR37L1 is an orphan G-protein-coupled receptor, which is implicated in neurological disorders, but its normal physiological role is poorly understood. Its close homologue, GPR37, is implicated in Parkinson’s disease and affective disorders. In this study, we set out to characterize adult and middle-aged global GPR37L1 knock-out (KO) mice regarding emotional behaviors. Our results showed that GPR37L1KO animals, except adult GPR37L1KO males, exhibited impaired retention of aversive memory formation as assessed by the shorter retention latency in a passive avoidance task. Interestingly, the viral-mediated deletion of GPR37L1 in conditional knockout mice in the hippocampus of middle-aged mice also showed impaired retention in passive avoidance tasks, similar to what was observed in global GPR37L1KO mice, suggesting that hippocampal GPR37L1 is involved in aversive learning processes. We also observed that middle-aged GPR37L1KO male and female mice exhibited a higher body weight than their wild-type counterparts. Adult and middle-aged GPR37L1KO female mice exhibited a reduced level of serum corticosterone and middle-aged GPR37L1KO females showed a reduced level of epinephrine in the dorsal hippocampus in the aftermath of passive avoidance task, with no such effects observed in GPR37L1KO male mice, suggesting that lack of GPR37L1 influences behavior and biochemical readouts in age- and sex-specific manners.

Abstract With the development of science and technology, the battlefield environment of modern warfare has become complicated and complex, and it has become an important task to obtain information about enemy targets quickly and accurately. Accordingly, researchers from various countries have explored various positioning methods, which can be divided into active and passive positioning, among which passive positioning has received more attention due to its excellent concealment and anti-jamming ability. In this paper, the two methods of passive positioning, Direction of Arrival (DOA), and Time Difference of Arrival (TDOA), are used to study the positioning of missile formations in two- and three-dimensional space and to analyse the factors affecting their positioning accuracy.

Abstract Aiming at the problem of how to reasonably correct the position of UAV formation, we take the circular formation composed of 10 UAVs and the conical formation composed of 15 UAVs in the same plane as examples to study how to adjust the number and angle of UAV signal transmission so that the UAVs in the entire formation are in the designated position. This paper uses geometric model, greedy strategy and other methods, uses python, matlab and other software to obtain a reasonable and effective mathematical model, and makes a test and evaluation. The research results show that no matter circular, conical or other graphics, we can construct a triangle by connecting the transmitting signal and the receiving signal UAV, and solve the problem to obtain the best transmitting signal angle and the minimum number of sorties required; If there is no triangle between the UAV transmitting the signal and each UAV receiving the signal, the UAV receiving the signal will not reach the designated position. Nowadays, the use of UAVs is more and more extensive. The cooperation of multiple UAVs can complete many functions such as detection and performance, which is also the significance of our research on how UAVs can better receive signals.

ABSTRACT We investigate one-halo galactic conformity (the tendency for satellite galaxies to mirror the properties of their central) in both star formation and morphology using a sample of 8230 galaxies in 1266 groups with photometry and spectroscopy from the Sloan Digital Sky Survey, morphologies from Galaxy Zoo and group memberships as determined by Yang et al. This is the first paper to investigate galactic conformity in both star formation and visual morphology properties separately. We find that the signal of galactic conformity is present at low significance in both star formation and visual morphological properties, however it is stronger in star formation properties. Over the entire halo mass range we find that groups with star-forming (spiral) centrals have, on average, a fraction 0.18 ± 0.08 (0.08 ± 0.06) more star-forming (spiral) satellites than groups with passive (early-type) centrals at a similar halo mass. We also consider conformity in groups with four types of central: passive early-types, star-forming spirals, passive spirals, and star-forming early-types (which are very rarely centrals), finding that the signal of morphological conformity is strongest around passive centrals regardless of morphology; although blue spiral centrals are also more likely than average to have blue spiral satellites. We interpret these observations of the relative size of the conformity signal as supporting a scenario where star formation properties are relatively easily changed, while morphology changes less often/more slowly for galaxies in the group environment.

This study aims to analyze the errors in the construction of Japanese passive sentence. This research involves Indonesian Japanese language students of semester IV. The sample of this research is Indonesian essay in 200 words. Quantitative and qualitative methods are used based on the error establishment definition of Japanese passive sentence Ichikawa (2005). The research result shows that the students make mistake in changing the Japanese passive verb form by 53%, the error in particle selection as much as 24%, the error in the subject structuring and object complement 18% and error in sentence formation of Yari-morai (giving-taking) as much as 5%.The error in changing the Japanese passive verb form is caused by a lack of practice and understanding of Japanese passive forms. Error in particle selection is caused by negative transfer factor. The lack of students 'understanding of the formation of Japanese passive sentences causes learners to tend to arrange subjects and principals' objects in Japanese passive sentences following the Indonesian passive sentence arrangement rules. The results of this study can provide an overview for Japanese language teachers, especially about the acquisition of learning passive Japanese sentence language among Indonesian students to be able to make a variety of a more creative teaching.

Abstract The practical applications of unmanned aerial vehicle (UAV) formation passive localization demand high accuracy and anti-interference ability. In this paper, a novel passive localization model based on analytical geometry and improved damped Gauss-Newton optimization method is proposed, which incorporates the improved damped Gauss-Newton algorithm and the error-based iterative algorithm for real-time coordinate correction of formation. Through Matlab simulation experiments, the proposed error-based iterative algorithm can stabilize the flight formation after only 24 iterations, and the distance error between each UAV and the specified position is only 1.2%. Moreover, in the case of signal loss, only four UAVs are required to transmit signals to localize a circular flying formation consisting of 10 UAVs. The model provides a theoretical method for passive localization and control of UAV formations in purely azimuthal flights.

In this paper, passive positioning technology in UAV formation is studied, and how to achieve effective positioning through signal transmission when UAV deviates is analyzed. The research shows that when four UAVs with transmitting signals are deployed, the positioning accuracy of feature point FY08 is very high, indicating that the positioning of UAVs can be effectively realized by setting four signal transmitting UAVs (including two new UAVs) when the location is unknown.In a typical formation of ten drones, nine are evenly distributed around the circumference, with the central drone being the FY00. By building a passive reception model, this paper discusses how to use the signals of FY00 and two other UAVs for positioning. When the drone deviates and receives signals from FY00, FY01 and another unknown drone, up to three drones are required to transmit signals to ensure effective positioning.The positioning model is derived by cosine law, and the linear distance between the deviating drone and the center drone is solved by geometry and sine theorem. Finally, the advantages of four signal transmitting UAVs in positioning accuracy were verified by measuring deviation and variance, and a conclusion was drawn that effective positioning of UAVs was achieved by signal transmitting under the condition of deviation.

The effect of passive backup force in drilling composite materials was investigated in this study. The passive backup force formation is due to material reacting and bending. The theoretical analysis indicated that the passive backup force has a significant effect on prevention of delamination damage in drilling composite materials. When the is large enough, the effects of the passive backup force and material behavior will be attenuated.

This article talks about the formation of passive-aggressive personality adaptation in a client, a supposed family system in which he grew up, the role of passivity in the client’s life and his favorite roles in communication with others. Passive-aggressive clients are among the most difficult in the therapist’s work, as they do not seek to achieve results in therapy, but rather to devalue the therapist’s work and avoid any changes. Avoidance and devaluation are the result of the fact that the active energy of such clients, which could have been directed at growth and development, was somehow blocked in their childhood. This article suggests a review of the views of several authors on a passive-aggressive client, allowing you to see better the hidden benefits of a person and his or her loved ones. In particular, the author draws on the works of Francis Bonвs-White, Aaron Wolfe Schiff and Jackie Lee Schiff, Ian Stewart and Van Joines. The article also describes the first steps in establishing contact with passive-aggressive clients in a session.

The semiconductor properties of passive films formed on AISI 316 stainless steel in sulfuric acid solution were studied by employing Mott-Schottky analysis in conjunction with the point defect model. The donor density of the passive films, which can be estimated by the Mott-Schottky plots, changes depending on the film formation potentials. Based on the Mott-Schottky analysis, an exponential relationship between donor density and the film formation potentials of the passive films was developed. The results showed that the donor densities evaluated from Mott-Schottky plots are in the range 2-3 × 1021 cm−3and decreased with the film formation potential. By assuming that the donors are oxygen ion vacancies and/or cation interstitials, the diffusion coefficient of the donors, (), is calculated to be approximately 3.12 × 10−16 cm2/s.

This study compares the formation of passive verbs in Modern Standard Arabic and Palestinian Arabic. It examines the morphological differences between the two types of verb formation, arguing that they result from the component of the grammar where passivization takes place, the lexicon and the syntax. It addition, the paper examines gaps in passive formation in Palestinian Arabic showing that these gaps are not always accidental but can be explained by morphological criteria and can be accounted for only in a word based view.

The emergence of passive galaxies in the early Universe results from the delicate interplay among the different physical processes responsible for their rapid assembly and the abrupt shut-down of their star formation activity. Investigating the individual properties and demographics of early passive galaxies improves our understanding of these mechanisms. In this work we present a follow-up analysis of the z > 3 passive galaxy candidates selected by Merlin et al. (2019, MNRAS, 490, 3309) in the CANDELS fields. We begin by first confirming the accuracy of their passive classification by exploiting their sub-millimetre emission to demonstrate the lack of ongoing star formation. Using archival ALMA observations we are able to confirm at least 61% of the observed candidates as passive. While the remainder lack sufficiently deep data for confirmation, we are able to validate the entire sample in a statistical sense. We then estimate the stellar mass function (SMF) of all 101 passive candidates in three redshift bins from z = 5 to z = 3. We adopt a stepwise approach that has the advantage of taking into account photometric errors, mass and selection completeness issues, as well as the Eddington bias, without any a posteriori correction. We observe a pronounced evolution in the SMF around z ∼ 4, indicating that we are witnessing the emergence of the passive population at this epoch. Massive (M > 1011 M⊙) passive galaxies, only accounting for a small (< 10%) fraction of galaxies at z > 4, become dominant at later epochs. Thanks to a combination of photometric quality, sample selection, and methodology, we overall find a higher density of passive galaxies than in previous works. The comparison with theoretical predictions, despite a qualitative agreement (at least for some of the models considered), denotes a still incomplete understanding of the physical processes responsible for the formation of these galaxies. Finally, we extrapolate our results to predict the number of early passive galaxies expected in surveys carried out with future facilities.

ABSTRACT We analyse the role of AGN feedback in quenching star formation for massive, central galaxies in the local Universe. In particular, we compare the prediction of two semi-analytic models (l-galaxies and sage) featuring different schemes for AGN feedback, with the SDSS DR7 taking advantage of a novel technique for identifying central galaxies in an observational data set. This enables us to study the correlation between the model passive fractions, which is predicted to be suppressed by feedback from an AGN, and the observed passive fractions in an observationally motivated parameter space. While the passive fractions for observed central galaxies show a good correlation with stellar mass and bulge mass, passive fractions in l-galaxies correlate with the halo and black hole mass. For sage, the passive fraction correlate with the bulge mass as well. Among the two models, sage has a smaller scatter in the black hole–bulge mass $({M_{\rm BH}-M_{\rm Bulge}})$ relation and a slope that agrees better with the most recent observations at z ∼ 0. Despite the more realistic prescription of radio-mode feedback in sage, there are still tensions left with the observed passive fractions and the distribution of quenched galaxies. These tensions may be due to the treatment of galaxies living in non-resolved substructures and the resulting higher merger rates that could bring cold gas which is available for star formation.

AbstractAt redshift z~1.7 the Universe was at the peak of its star-formation activity. It is thus a puzzle why some galaxies, many of them very massive (M* ⩾ 1011 M⊙), had already chosen to stop forming stars. These ultra-massive galaxies, guaranteed to be the central galaxies of their host dark matter halos, must have attained very high rates of star formation to assemble their stellar masses in such a short amount of time. Using the largest (to date) K-selected gzKs survey of passive galaxies (in an effective area of ~ 27.5 deg2) we study the demographics of these dead monsters, hoping to help understand the quenching mechanism that shut them down.

The aim of the present study was to test whether titin is a calcium-dependent spring and whether it is the source of the passive force enhancement observed in muscle and single fiber preparations. We measured passive force enhancement in troponin C (TnC)-depleted myofibrils in which active force production was completely eliminated. The TnC-depleted construct allowed for the investigation of the effect of calcium concentration on passive force, without the confounding effects of actin-myosin cross-bridge formation and active force production. Passive forces in TnC-depleted myofibrils ( n = 6) were 35.0 ± 2.9 nN/ μm2 when stretched to an average sarcomere length of 3.4 μm in a solution with low calcium concentration (pCa 8.0). Passive forces in the same myofibrils increased by 25% to 30% when stretches were performed in a solution with high calcium concentration (pCa 3.5). Since it is well accepted that titin is the primary source for passive force in rabbit psoas myofibrils and since the increase in passive force in TnC-depleted myofibrils was abolished after trypsin treatment, our results suggest that increasing calcium concentration is associated with increased titin stiffness. However, this calcium-induced titin stiffness accounted for only ∼25% of the passive force enhancement observed in intact myofibrils. Therefore, ∼75% of the normally occurring passive force enhancement remains unexplained. The findings of the present study suggest that passive force enhancement is partly caused by a calcium-induced increase in titin stiffness but also requires cross-bridge formation and/or active force production for full manifestation.

This study explains the existing and real conditions of a possible passive elimination of static electricity when loading oil and oil derivatives. We are considering the formation and survival of gas bubbles both in the volume of oil in its depth, but also at the surface of oil and oil derivatives of the partly filled reservoir, and formation of both volume and surface electric charge in oil and oil derivatives. The study presents the research of formation and survival of static electricity in both reservoirs and tank trucks of different geometric shapes partly filled with oil and oil derivatives. We are proposing a new original possibility of passive elimination of static electricity when loading oil and oil derivatives in reservoirs and tank trucks. The proposed passive device for elimination of static electricity is protected at the international level in the domain of intellectual property (with a patent, model and distinctive mark).

The difficulty of forming passive vocabulary while reading texts in a foreign language is one of the most pressing challenges in foreign language teaching. Many Russian and international linguists have addressed the issue of developing passive vocabulary and the efficiency of its formation, but only the development of computer technology in recent decades has made possible the laying out a structured approach to the process of selection, storage and memorizing foreign words while reading. This article examines the problem of the formation of passive voca-bulary and analyzes the interrelation of receptive and reproductive vocabulary according to the opinion of international and Russian researchers. A conclusion is made about the need for func-tional differentiation of receptive and reproductive linguistic material, as well as for ensuring the repeatability of lexical units for developing actual passive vocabulary. A hypothesis about the prospects of applying information technology while resolving this problem is generated. The de-velopment technology and structure of a computer application are described, as well as its main modules, classes and the structure of its interface. The methodology of an experiment aimed at confirming the effectiveness of the applied technologies and the results of a test passed by the ex-periment’s participants are presented. The hypothesis is confirmed. Further theoretical and practical studies of the problem of the formation of passive vocabulary are warranted. The possibility of adding new language pairs to the application and searching for other ways to form receptive vocabulary using computer technology is proposed.

In this paper, we study IR spectroscopy system design by optimizing the radiation energy in the plane of the surface temperature and wavelength. We provide infrared system designing criteria towards the formation of the optimized image of an arbitrary radiating body. As per this formulation, we find that an optimal image arises via an intrinsic statistical measure as late time thermal effects. We also outline the qualitative characteristics of the thermal radiation energy and associated quantities undermining its stability. This classifies (un)stable radiation zone detection towards cutting edge IR based information theory research & development in designing of thermal detectors. Finally, we discuss perspective applications of the IR technology, ensemble averaging, digital coding, and formation of an optimal thermal image.

Passive mechanical properties of strips of rabbit detrusor smooth muscle were examined and found by cyclic loading in a calcium-free solution to display viscoelastic softening and strain-induced stress softening (strain softening). Strain softening, or the Mullins effect, is a loss of stiffness attributed to the breakage of cross-links, and appeared irreversible in detrusor even after the return of spontaneous rhythmic tone during 120 min of incubation in a calcium-containing solution. However, 3 min of KCl or carbachol (CCh)-induced contraction permitted rapid regeneration of the passive stiffness lost to strain softening, and 3 μM of the RhoA kinase (ROK) inhibitor Y-27632 prevented this regeneration. The degree of ROK-induced passive stiffness was inversely dependent on muscle length over a length range where peak CCh-induced force was length independent. Thus rabbit detrusor displayed variable passive stiffness both strain- and activation-history dependent. In conclusion, activation of ROK by KCl or CCh increased passive stiffness softened by muscle strain and thereby attributed to cross-links that remained stable during tissue incubation in a calcium-free solution. Degradation of this signaling system could potentially contribute to urinary incontinence.

This article critically engages with debates on uneven and combined development and particularly the lack of attention given in this literature to accounts of spatial diversity in capitalism’s outward expansion as well as issues of Eurocentrism. Through interlocutions with Antonio Gramsci on his theorising of state formation and capitalist modernity and the notion of passive revolution, we draw out the internal relationship between the structuring condition of uneven and combined development and the class agency of passive revolution. Interlocuting with passive revolution places Antonio Gramsci firmly within a stream of classic social theory shaping considerations of capitalist modernity. As a result, by building on cognate theorising elsewhere, passive revolution can then be established as a lateral field of causality that necessarily grasps spatio-temporal dynamics linked to both state and subaltern class practices of transformation in social property relations, situated within the structuring conditions of uneven and combined development.

Personalized laser powder bed fusion (PBF-LB/M) Ti-6Al-4V (TC4) has a broader application prospect than that of traditional casting. In this paper, the composition and corrosion resistance of the passive film formation mechanism of TC4 prepared by optimization of PBF-LB/M techniques and traditional casting were systematically studied in 0.9 wt.% NaCl at 37 °C by electrochemical technique and surface analysis. The rates of the passive film formation process, corrosion resistance and composition of TC4 show different characteristics for the different preparation processes. Although the rate of passive film formation of cast-TC4 was higher at the initial immersion, the open circuit potential was more positive, and the film thickness was larger after stabilization, those facts show no positive correlation with corrosion resistance. On the contrary, with no obvious defects on the optimized PBF-LB/M-TC4, the passive film resistance is 2.5 times more, the defect concentration is reduced by 30%, and the TiO2 content is higher than that of the cast-TC4, making the martensitic-based PBF-LB/M-TC4 exhibit excellent corrosion resistance. This also provides good technical support for the further clinical application of PBF-LB/M-TC4.

AbstractThis chapter provides comprehensive descriptions of 52 numbered formations/rock units of the Southeastern Oman Mountains, based on available literature. The oldest eight siliciclastic and carbonate formations are positioned below the ‘Hercynian’ Unconformity. The overlying formation (9–16) mostly represent carbonates which accumulated in a passive margin platform setting during or after the opening of the Neo-Tethys Ocean. The passive margin slope and platform collapsed during the late Cretaceous because of the obduction of the Semail Ophiolite along with the deep marine Hawasina sedimentary rocks. The collapsing passive margin interval was recorded within the syn-obductional Aruma Group (17; Muti Formation). Above this formation are the allochthonous units (18–42) of the tectonically lower Hawasina deep-sea basin and the structurally overlying Semail Ophiolite. The former contains Permian to Upper Cretaceous formations, while the latter is Cenomanian in age. Above the allochthonous rocks, the Neo-autochthonous formations were deposited, starting with the post-obductional uppermost Cretaceous Aruma Group (43; Al-Khod Formation) until the Quaternary deposits (52). All these formations/rock units are depicted on an accompanying map and stratigraphic chart.

Abstract Kinetics of passive film formation on the bare surface of scratched stainless steels SS in magnesium chloride (MgCl2) solutions were studied using the rapid scratching technique under potentiostatic conditions. An experimental device was designed to record data at the rate of 20,000 points/s, with the rotating rate of the specimen at 3,000 rpm and a scratch scar length of about 4.6 mm to 4.8 mm. A new phenomenon was observed in that two peaks were seen rather than a continuous decay in the curve of current decay on scratched SS in MgCl2 solutions. Current decayed steeply to approximately passive current within about 2.5 ms to 3 ms after the diamond knife was moved away from the specimen. Current rose again for about 2 ms to 3 ms. This phenomenon was considered to represent the processes of adsorbed layer formation on the bare surface and transformation of the adsorbed layer into a passive film. Results were affected by the recording rate of experimental data, the specimen rotating rate, and the scratch scar length. The kinetics of passive film growth were shown empirically by i(t) = I0exp(−βt) with I0 and β being constants. Passive film growth was controlled by ion conduction in a strong electric field, as defined by i = A exp(BV/x).

Both active and passive full waveform acoustic loggings (FWAL), complemented by a flow log, were conducted in a borehole of an experimental site located in the Cher region (France).. The acoustic tool used for the FWAL experiments is a flexible monopole tool holding a pair of piezoelectric receivers and a magnetostrictive transducer. The tool was modified to perform both active and passive FWAL. For passive acoustic logging, several runs were recorded to obtain a set of acoustic noise sections. As the noise is simultaneously recorded by two receivers of the tool, an interference noise section was elaborated by correlating or deconvolving the pair of signals and then summing these pairs of acoustic traces at each depth. This procedure, which can be interpreted as an interferometry analysis, points out the presence of low-frequency waves identified as Stoneley waves. The velocity and RMS amplitude of the Stoneley wave were computed at each depth. It is shown that: 1- the Stoneley wave velocity obtained in passive mode can be used to estimate the shear velocity of the formation, 2- the RMS amplitude and velocity variations of the Stoneley waves are strongly correlated with the variations of the flowmeter.
