Full textAbstract:
La première partie cherche à définir l'exotisme et les étapes de l'évolution de la notion en littérature. La deuxième partie souligne la différence entre le succès de l'exotisme dans le grand public, entre 1870 et 1918, et son succès chez les écrivains, soucieux de s'opposer à la mentalité dominante de leur époque. L'étude du champ littéraire permet de situer Loti et Segalen dans la littérature de cette période. Les trois dernières parties montrent que Loti et Segalen partagent une même conception de l'exotisme : hostiles au tourisme comme au colonialisme, ils définissent une distance géographique et temporelle entre l'ici et l'ailleurs; s'identifiant à l'Orient et à la Chine, ils témoignent d'une identité éclatéeThe first part aims at defining exoticism and the succesive stage of the evolution of this notion in literature. The second part emphasizes the difference between the wides pread appeal of exoticism among the public, from 1870 to 1918, and among the writers, who wish to react against the prevailing mentality of their time. A close study of the literary field allow us to place loti and segalen in the literature of this time. The last three parts show that loti and segalen share a common conception of exoticism : as opponents to "tourism" and "colonialism", they set a time and geographical distance between what is "here" and "there"; by identifying themselves with the far east and china, they be tray a "split" identity

Full textAbstract:
Pierre Loti est encore considéré par bien des lecteurs comme désuet, voire complètement démodé. Or le démodé est en réalité une caractéristique essentielle de l’homme et de son style. Cette étude démontre que le temps est une clef de lecture fondamentale pour aborder l’œuvre de Loti et comprendre une esthétique qui trahit sa relation au monde, plus temporelle que géographique. Loti n’est rien moins qu’obsédé par le temps, par un temps qui engendre inexorablement la perte – une perte tout à fait ambivalente puisqu’elle est positive dans sa négativité, désirée comme redoutée. Le passé est rassurant parce qu’intangible. Cette recherche explore l’enfance de Loti comme souvenir rétrospectif, construction littéraire et création d’un mythe personnel. L’enfance est le paradis perdu que Loti regrettera toujours avec une profonde mélancolie, tandis que ses voyages ultérieurs formeront une recherche d’Éden, mais d’un Éden qui apparaît toujours déjà en ruine. L’essai propose aussi une analyse de l’élaboration d’une identité hétéronymique : c’est par les pouvoirs de la littérature, du transvestissement, du divertissement nocturne et des scénographies du moi que Julien Viaud devient Pierre Loti. Ce nouveau soi, concourant et non concurrent de l’autre, doit être vu comme une construction comblant les pertes de sa propre vie. De manière similaire, la mort de son frère aîné détermine sa recherche d’une mâle altérité, tant fictive que réelle, tout comme elle innerve son œuvre de nouvelles disparitions qui rejouent l’originelle. L’étude analyse également la mise en scène de l’échec dans différents romans de l’auteur, la mort des héros amenant à une démonstration de la fascination de Loti pour la mort. Enfin, l’œuvre de Loti est passée au crible de la mélancolie de son regard, de la nostalgie de son écriture et de la fadeur de son style, dans le but de révéler l’ampleur de sa prédilection pour le passé, toujours préféré au présent ou à l’avenir. Et cela parce que le passé, même chimérique, est le seul refuge contre la vanité de l’existencePierre Loti is still considered by most readers as old-fashioned. But being old-fashioned, or even moreout-of-fashion is an essential characteristic of Loti’s mind and stylistics. This study aims at showing how time isa fundamental key in reading Pierre Loti’s books and in understanding his aesthetics, which betray his rathertemporal than geographic relationship to the world. Loti is not less than obsessed by time: time goes by in apermanent flow that generates loss – an ambivalent loss which is both positive and negative, desired and feared.The past is comforting because intangible. This research explores Loti’s childhood as a retrospective memory, aliterary construction and a mythologizing of self. Childhood is a paradise lost which Loti will always regret witha deep melancholy as his own travels can be seen later on as a quest for Eden, but for an Eden that will alwaysappear already ruined. Then, the essay suggests an analysis of the construction of a heteronymic identity: JulienViaud becomes Pierre Loti by the powers of literature, travesty, parties’ entertainment and scenographies of theself. This other self, completing, not competing with the other one, can be considered as a construction fulfillingthe losses of his own life. In the same manner, the death of his older brother determines his search of fictive andreal manly otherness, as well as it innervates his work with further disappearances replaying the original one.Therefore, the essay highlights the staging of failure in different novels of the author, the death of heroes leading to an explanation of Loti’s fascination for death. At last, Loti’s work is being looked over through thecriteria of melancholy of sight, nostalgia of writing and blandness of stylistics, in order to unveil the width of hisfondness for things past, always preferred to the present ones, or to events to come. An this because the past –even if chimerical – is Loti’s only refuge against his feeling of the vanity of life

Full textAbstract:
La vie de pierre loti, source de son oeuvre et point de depart de cette etude, manifeste l'importance de la figure maternelle, tres idealisee. Elle n'apparait pas seulement dans les textes autobiographiques. Les romans et relations de voyage representant l'autre, francais ou etranger, homme comme femme, temoignent de l'impossibilite d'une relation du fait, precisement, de cet attachement a la mere. C'est du moins ce que montre cette etude. La mort de l'heroine exotique qui, adulee ou execree, n'est jamais vraiment consideree comme sujet, et le sort malheureux de la fiancee francaise confirment l'echec de la rencontre entre le voyageur et l'autre-feminin. Fatou-gaye, amante et mere senegalaise constitue une exception notable. Le voyageurnarrateur semble mieux en compagnie des marins, en qui il trouve des "freres". Souvent bretons, ils sont caracterises, comme le spahi cevenol et le basque ramuntcho, par leurs particularismes regionaux. Tous sont proches des "primitifs" tahitiens ou africains que le voyageur n'a pas rejoints, les jugeant trop "rudes", pas plus que les asiatiques, trop occidentalises. L'inde le tient trop a l'ecart pour le seduire. Mais l'orient, lieu du temps immobilise, l'attire. C'est l'occasion de tableaux ou l'autre n'est que figurant avant d'etre gomme. Car l'espace depeint se vide au fil de l'oeuvre. La mer n'est qu'en apparence acces a l'ailleurs et a l'autre. Le gout du voyageur pour les espaces vides (le desert, la mer) ou fermes (l'ile, la grotte, celle du jardin natal notamment) le confirme. Il n'a cherche qu'a rejoindre son enfance, pas a ller vers les autres dont il minore, finalement, la diversite, concluant sur l'universel besoin de croire et d'aimer qu'il n'a pu lui-meme satisfaire. S'il n'est plus, au terme de ses periples, nulle part "chez lui", du moins a-t-il acquis, au milieu de toutes ces mises en scene, l'identite de l'ecrivainThe life of pierre loti, origin of his oeuvre and starting point of this thesis reveals the importance of the very idealized mother figure. She does not only appaer in his autobiographical texts. His novels and the relations of his travels recounting the other, either french or foreign, man or woman, attest the impossibility of making close relationships because of this particular attachment to the mother. This aspect is developed in this thesis. The death of the exotic heroine who, whether adored or detested is never really considered as a human being, and the unfortunate fate of the french fiancee confirm the failure of the encounter between the traveller and the feminine-other. The only notable exception being fatou-gaye, the senegalese lover and mother. The travellernarrator seems to feel better in the company of sailors whom he sees as brothers. Often from brittany, they show regional peculiarities like the spahi from the cevennes and the basque ramuntcho. All of them are similar to the primitive people from africa or tahiti that the traveller has never reencountered, thinking they are too crude, nor the too westernized asian people. India keeps him too far away to seduce him. On the contrary, the orient where time stands still, attracts him. It offers him paintings where the other is only an apparition before being erased. For the canvas clears in the course of his writing. The sea has only the appearance of a means of access to somewhere else and also to the other. The taste of the traveller for wide spaces (deserts, seas) or enclosed areas (islands, caves, especially of his chilhood garden) confirms this feeling he was constantly searching to return to his childhood rather than to get closer to the others, whom finally he reduces in variety. He ends with a universal need of belief and love which he was not able to fulfill for himself. At the end of his journeys, if there is nowhere he feels at home, at least, he has learned through all his scenes, the identity of the writer

Full textAbstract:
Pierre Loti a abordé et décrit bien des pays dans le monde entier. Surtout en ce qui concerne l'Extrême-Orient - la Chine, la Corée, et le Japon - la valeur documentaire des textes de cet écrivain, confirmée par des éléments externes, est remarquable. L’esprit, l'attention, l'émotivité de Loti face à ces trois pays qu'il perçoit et juge sont souvent de façon imprévisible et surprenante. L’espace naturel et humain, des êtres qui l'animent et le particularisent, des potentialités culturelles, esthétiques qu'il renferme, ce sont les trois modes d'une même expérience contrastée, ambivalente, dominée par l'excès, l'hypertrophie des impressions. Cette division de l'image tient compte d'une évidence. Loti est parti du plus superficiel, de l'anecdotique, du quotidien, pour accéder à l'universel, à la confirmation de sa philosophie implicite des choses et des êtresPierre Loti has approached and described on many countries in the world. Particularly, China, Korea and Japan as far as the Far East are concerned. The documentary value of this writer's texts confirmed by external elements is outstanding. Loti’s regard, emotive and response towards these three countries he perceives and judges are often surprising and unexpected to the reader. His natural and human frameworks with the people who animate and particularize it, his forceful cultural and aesthetic potentialities are the two modes of a contrastive, ambivalent experience dominated by excess, hypertrophic impressions. This division of the image brings the following truth to light. Loti is keen on working on the more superficial, anecdotic details of the everyday life to accede to the universal and to the confirmation of his inner philosophy on things and beings

Full textAbstract:
Notre these intitulee "la poetique de l'orient dans l'oeuvre de pierre loti" situe l'exotisme et l'orientalisme lotiens dans une longue tradition d'exotisme et d'orientalisme et developpe l'ecriture "apoetique" de l'alterite qui en resulte. En ayant recours aux materiaux linguistiques, nous analysons l'image enchantee, en voie de desenchantement et apocalyptique de l'orient que loti superpose plus qu'il n'oppose. Notons que la version enchantee applique le reve a l'orient non seulement comme une metaphore mais aussi comme un processus onirique. Quant a la version desenchantee, elle met en cause, pour decrire le mouvement agonisant de l'orient, le modernisme et les touristes. De meme, nous dedoublons les investigations enonciatives par une etude intertextuelle qui renvoie aux contes des mille et une nuits, au conte de la belle au bois dormant et a l'apocalypse de saint jean. Notre etude de la prose poetique lotienne traite la fonction taxinomique du chiffre "trois", les procedes mathesiques (peregrenisme ; citations bibliques, coraniques et islamiques ; lettres enchassees). D'autre part, nous rapprochons la technique d'interruption exercee par loti de celle de la poesie en prose. Motives par la carriere picturale de l'auteur, nous etudions le traitement de la lumiere dans ses descriptions. Enfin, nous confrontons dans une etude intersemiotique quelques dessins de pierre loti avec les supports descriptifs qui leur correspondentOur thesis, the poetry of the east in pierre loti's works, replaces loti's exoticism and orientalism in a long tradition of exotic and oriental writing and develops the style of apoetical otherness resulting from it. Starting from linguistic material, we have analysed loti's image of the east, an image at once enchanted, in the process of being disenchanted and apocalyptic. Let us remark that the enchanted version applies the dream pattern to the east not only as a metaphor but also as an oneiric process. As for the disenchanted version of the east, it makes modernism and the tourists responsible for what he describes as the death struggle of oriental countries. Similarly, we have substantiated our study of enunciation through an intertextual approach including comparisons with the arabian nights, sleeping beauty and saint john's revelation. Our study of loti's poetical prose deals with the taxinomic function of the figure "three" and mathesic procedures (such as peregrenism, quotations from the bible, the koran and other islamic texts, embedded letters). Moreover, we have compared loti's interruption technique with its equivalent in prose poetry. Loti's achievements as a painter have proved an interesting basis for the study of his treatment of light in descriptions. This approach has finally led us to undertake an intersemiotic analysis of some of loti's drawings, comparing them with the cooresponding descriptions

A partir de la notion récente et encore discutée d'autofiction, sont analysés quatre récits de Pierre Loti, formant une tétralogie par leur cohérence géographique, chronologique et dramatique : "Aziyadé" (1879), "Fantôme d'Orient" (1892), "Les Désenchantées" (1906) et "Suprêmes visions d'Orient" (1921). Il s'agit de dégager une poétique lotienne en explorant l'ensemble des pratiques d'écriture qui fondent la dérive générique autofictionnelle : jeux de pseudonymes, pactes de lecture implicites à travers le paratexte et les différentes modalisations du texte, métalepses et figures en abyme, temps et lieu narratifs semi-mythiques, traitement héroïque et fantastique du héros narrateur, omniprésence enfin de l'intertexte avec une très forte proportion de l'autotextualitéBased on the recent and still debated notion of autofiction, four narrations of Pierre Loti, making up a tetralogy by their geographical, chronological and dramatic coherence, will be analyzed : Aziyadé (1879), Fantôme d’Orient (1892), Les Désenchantées (1906) et Suprêmes visions d’Orient (1921). This work's aim will be to bring out a lotian poetic through the exploration of a set of writing techniques founding the autofictional generic drift : play on pseudonyms, implicit reading pacts through the paratext and the various text modalizations, metalepses and intertwined figures, semi-mythical narrative time and space, heroic and fantastic approach of the hero narrator, omnipresence at last, of the intertext with a considerable proportion of autofiction

Full textAbstract:
Abstract Noise and vibration reduction is a critical concern in planetary gear applications. During the design process, system parameters are varied to evaluate alternative design choices, avoid resonances, optimize load distribution, and reduce weight. It is important to characterize the effects of parameter variations on the natural frequencies and vibration modes for effective vibration tuning. In planetary gear dynamic models (Figure 1), the key design parameters include the mesh stiffness, support/bearing stiffness, component mass, and moment of inertia. Some plots of natural frequencies versus planetary gear parameters are presented by Cunliffe et al. (1974), Botman (1976), Kahraman (1994), and Saada and Velex (1995). Lin and Parker (1999a) analytically characterized the unique, highly-structured properties of planetary gear natural frequency spectra and vibration modes. They also derived simple, closed-form expressions for the sensitivities of natural frequencies and vibration modes to these parameters (Lin and Parker, 1999b). The natural frequency plots in the above literature show natural frequency veering phenomena where two eigenvalue loci approach each other as a parameter is varied but then abruptly veer away like two similar charges repelling (Figure 2a). The phenomenon has been extensively studied (Leissa, 1974; Perkins and Mote, 1986; Pierre, 1988; Chen and Ginsberg, 1992; Happawana et al., 1998). The vibration modes of the veering eigenvalues are strongly coupled and undergo dramatic changes in the veering neighborhood. Eigenvalue veering is also related to mode localization that can occur when disorder is introduced into nominally symmetric systems like turbine blades, space antennae, multi-span beams and other structures (Pierre, 1988). In the case of especially sharp veering, it is sometimes difficult to distinguish between intersection and veering just by observing eigenvalue plots. Curve veering/crossing complexity obstructs the tracing of eigenvalue loci under parameter changes. Also, when multiple curves veer or intersect close together (Figure 3), strong modal coupling (and associated operating condition response changes) occurs that is not identifiable from frequency loci plots. The objective of this work is to analytically characterize the rules of eigenvalue veering in planetary gear vibration. The special veering patterns derived here help to trace natural frequencies and examine impacts of design parameters on vibration. These veering patterns, combined with the unique modal properties (Lin and Parker, 1999a) and the eigensensitivies analysis (Lin and Parker, 1999b), provide designers considerable insight into planetary gear free vibration.

Abstract In the early 19th century, Thomas Young (1805) and Pierre Simon Laplace (1806) published the concept of fluid surface tension, which made great contributions to the theory of surface tension. Many scholars continued to study electrowetting-on-dielectric (EWOD) technology, hoping to effectively control the movement of droplets, to make a lot of microchannels in biomedical and life applications. The purpose of dielectric and hydrophobic layer is to prevent the droplet from short circuiting when the electrode moves, and the increase of hydrophobic layer will improve the smoothness of droplet movement. EWOD technology is used in this research as the prelude of the development of soft robot. Through the combination of finger electrode and electrowetting-on-dielectric technology, a carrier is designed. The drop is driven by Arduino and LabVIEW control software, and the carrier can be moved effectively. The effective distance between the finger electrodes was found out from the experiment to change the contact angle of the drop. Drop material will use two kinds of materials, PC and mixed liquid (PC, UV), try to change the contact angle and its strength through the voltage of 0–250V, so as to find out the maximum force and suitable contact angle, hoping to support the carrier effectively. Finally, the carrier will be transported to the designated position by using drops.

Full textAbstract:
The independent code assessment constitutes an important part in the qualification of an analytical tool for performing licensing or NPP support activities. The consistent application of adopted modeling procedures together with qualified experimental database plays a key role in the code assessment process. It should be mentioned that a consistent code assessment supported by a qualified experimental database is an important step for developing a solid ground for the uncertainty evaluation in the frame of Best Estimate Plus Uncertainty (BEPU) approach. The assessment of RELAP5-3D code capabilities for reproducing various accident and transient in PWR-like experimental Integral Test Facilities (ITF) has been performed at the Nuclear Research Group of San Piero a Grado (GRNSPG) of University of Pisa. The present paper summarizes the first series of this activity, aimed for RELAP5-3D assessment at Large Break LOCA and Small Break LOCA conditions. In this framework, 2 LBLOCA and 2 SBLOCA experimental tests performed at LOBI, LOFT and SPES ITF have been simulated by RELAP5-3D. First, an experimental database has been developed for mentioned facilities and experimental tests of interest. This process has been carried out following IAEA guidelines in Safety Series Report 23 and 52 and other known best practices. The elaboration of great amount of available information and adopting quality assurance procedures resulted in the standardized-form qualified Reference Data Sets (RDS) for each ITF. The second part of the paper discusses development of RELAP5-3D models for LOBI, LOFT and SPES facilities and simulation of the 4 tests, namely LOBI A1-06 and LOFT L2-5 (2A LOCA), and LOBI A1-83 and SPES SB-04 (10% CL LOCA and 6% CL LOCA respectively). All models were developed following the same nodalization techniques adopted at GRNSPG-UNIPI. All calculations were qualified both at steady-state and transient conditions applying the same set of qualitative and quantitative criteria. The judgment of RELAP5-3D code capabilities to reproduce the relevant thermal-hydraulic phenomena has been reported.

Full textAbstract:
A simple testing method to evaluate the influence of high pressure hydrogen gas up to 100 MPa on mechanical properties at the temperature between 20 K and up to 800 K had been developed. In this method, instead of using high-pressure gas vessels, high pressure gas was filled into a small hole in the hollow-type test piece from a hydrogen gas cylinder or a compressor for 10 MPa or 100 MPa test. A small inner diameter of the hole enables to evaluate also the reduction of area in the slow strain-rate tensile (SSRT) tests. The temperature of the test piece with the high pressure gas can be changed simply by surrounding coolant or heater between 20 K and 800 K. Lots of test results by this method proved that almost the same results were obtained between this method and the conventional method with high-pressure gas vessels where test piece is installed. The great advantages of this method are not only the less cost for the facilities of high-pressure vessels but also the ability of tests at lower or higher temperatures than those with the vessels. So, this method is proposed to be used world-widely to evaluate the mechanical properties of structural materials for extremely severe environments, such as high-pressure hydrogen applications and also to study the mechanism of the influence of high-pressure hydrogen for design and reliability of those facilities. In this paper, the details of testing procedure of this method and results of tensile and fatigue tests in up to 70 MPa hydrogen gas on several kinds of stainless steels obtained by this method are presented.

Dr. Ganna Zaitseva participated a lot in researches conducted within the North-Western archaeological expedition of the State Hermitage Museum and elaborating the chronological timeframes for Neolithic in this region. Multidisci- plinary investigations of the last five years changed a lot historical schemes and environmental reconstructions made for Serteya II site, located in Smolensk region. The Serteya II site is a multilayer complex used by hunter–fisher–gath- erer communities in the 9th-8th mill. BC, and from the end of the 7th till the end of the 3rd mill. BC. Archaeological structures and horizons were developed in the palaeolake shore zone within changing water regimes and changes in the environmental conditions. Based on the most convergent dendrochronological sequences, two floating chronolo- gies were compiled, for pine wood 53 years old and larch wood 54 years old. Finally five OSL dates have been obtained, but the acquired age of geological ones significantly exceeded expectations. Three dates indicate the Neolithic period (contrary to expected XVII century), and a chronological inversion of OSL dates can be seen. Surprisingly spectrom- etry measurements of gytia sediments, despite of significant amount of organic matter allow as to calculate the dose rate and then to date one piece of Neolithic pottery. The obtained age perfectly corresponded to present state of knowledge.

Full textAbstract:
This paper presents the results of a study to assess the feasibility of inferring workpiece material hardness from high-speed video data of chip formation obtained during a turning operation. The motivation for assessing hardness in situ comes from the fabrication of shaped charges, where spatial variation in hardness is known to affect the performance of the shaped charge. While other in-process data could be used for this purpose, video data are analyzed here because of the stand-off, non-contact advantages afforded. This is especially relevant for highly qualified machining processes for small-lot, high value parts where any interference with the process (e.g., introduction of cables near the machine tool) is undesirable. A multistep image processing procedure is presented which is used to extract several features from the video data. These features are then used to develop a classifier which can be used to predict work-piece hardness. Multiple classifier designs (Knn and Ratchet) are considered.

Full textAbstract:
It has long been recognised that a defect experiencing a state of low constraint shows improved fracture properties when compared to the same defect in a highly constrained state. Fracture test specimens have, therefore, been designed in such a way as to generate a state of high constraint at the crack tip in order to ensure that the properties measured are conservative. Where a defect, in practice, is not highly constrained then using the fracture toughness measured from a standard test piece leads to an overly pessimistic assessment. With the move toward more accurate design and assessment due to the availability of advanced computational tools, it is advantageous to take this excessive conservatism into account. A particular case that is of interest is the effect that constraint has on the onset of upper shelf temperature (OUST). The OUST is typically defined as the intersection of the fracture toughness loci representing the 5% probability of cleavage and the 50% probability of ductile initiation. This paper details a method which can be used to predict the shift in OUST using the toughness scaling method proposed by Anderson and Dodds and extended to account for the influence of constraint on ductile initiation.

Full textAbstract:
Abstract As the Oil & Gas industry journeys towards net zero carbon emissions, a lot needs to be done, one of which is the adoption of digital transformation across companies. Decarbonization requires a transformational shift in the way companies operate, how they source, use, consume and think about energy and feedstocks. If the Oil & Gas sector will continue to exist, it must carry out its activities in the safest possible way and digitalizing it will help in achieving this. A survey by Newsweek shows that areas where transformative technologies are having the biggest impact are production-related, operations and maintenance, enhanced recovery, fracking/tight reservoirs, and exploitation at greater depths. Luis Abril of Minsait opined that digital technology enables companies to extract more value from data, using new platforms to share data with the entire organization, suppliers, contractors, and partners. The real-time visualization of data helps optimize decision making. Big data can be analyzed to find answers to questions such as: What piece of equipment is showing signs of wear and should be replaced? What sort of predictive maintenance can be leveraged? What is the most effective fracking approach for this well? AI helps to reduce routine flaring, employ methane capture, optimize production and reservoir management using digital tools such as IoT sensors, digital twins, and virtual reality to model scenarios, monitor operations, track emissions, energy usage and proactively maintain equipment, produce lower-emission products by moving from one hydrocarbon to another (e.g., from coal to natural gas) or creating another product (such as biofuels or syngas). Transformative technologies, particularly IoT, mobility and cloud applications are going to have a profound effect on the future of the oil and gas sector. Investment in these technologies cost a lot which might be difficult for private companies, but it is worth the money in the long run.

Full textAbstract:
Abstract The high quality of the thermally sprayed tungsten carbide coatings has been attributed to high particle velocity and relatively low particle temperature. Such thermal spray conditions can be obtained with the HVOF spray process. In comparison to the plasma spray process, in the HVOF spray process the high particle velocity and optimum particle temperature have been associated with very high gas velocity (>1000 m/s) and a relatively low gas temperature (< 2700 °C). In this work tungsten carbide coatings (WC-17Co) were sprayed by the HVOF process with a low and a high gas velocity of 1050 and 1560 m/s, respectively. The spray tests were carried out also with different hydrogen/oxygen ratios. The coatings were abrasion tested in order to find out how gas velocity and the fuel/oxygen ratio affect the coating quality and wear rate. Wear rates of the HVOF sprayed coatings were found to decrease with the higher combustion gas velocity. The coating quality and wear rate became also less sensitive to gas parameters with the increasing gas velocity. The coating microhardness and wear rate were also compared to hot isostatic pressed (HIP) reference material from the same spray powder lot. The HIP sintered test piece was found to be less wear resistant than the corresponding thermally sprayed coatings.

Full textAbstract:
Combine harvesters play a crucial role in grain harvest. Due to seasonal character of work of these machines is necessary to achieve high standard in durability and reliability during working period. There is lots of requirements that have to be done according to the crop type, field conditions and as well as high performance and lower costs. Combine harvesters are the main harvesting technology of cereals in the world and main piece of work should be done in short time. The aim of this paper is an economic analysis of combine harvester’s fleet in different working conditions. The evaluation is based on exact costs analysis of combine harvesters New Holland brand sort by different ages and different concepts of threshing. Used data were collected during all working seasons of combines. There is a data set from 10 seasons. There is two groups in evaluation - 9 machines NH CR 9080 and another 9 machines NH CX 8080. Working parameters evaluated are fuel consumption and operational costs. Thanks to on board computer we have data about performance of each machine per day and per whole season. Costs are calculated as fixed and variable and then summarized for every machine. The result shows that effect of costs analysis depends on annual performance of the machine. There is positive effect on depressing fixed cost due to higher performance in season. A special result of this study is evidence of intervenes reason during all seasons and setting up the coefficient of repairs for the group of combines.

Full textAbstract:
This qualitative study was undertaken as part of the work of the Foreign, Commonwealth and Development Office (FCDO) funded Inclusion Works programme which aims to improve inclusive employment for people with disabilities in four countries: Uganda, Kenya, Nigeria, Bangladesh. When the COVID-19 pandemic emerged early in 2020 the work of this consortium programme was adapted to focus on pandemic relief and research activities, while some other planned work was not possible. The Institute of Development Studies (IDS) led a piece of qualitative research to explore the experiences and perceptions of the pandemic and related lockdowns in each country, using a narrative interview approach, which asks people to tell their stories, following up with some further questions once they have identified their priorities to talk about. 10 people with disabilities who were involved in Inclusion Works in each country were purposively selected to take part, each being invited to have two interviews with an interval of one or two months in between, in order to capture changes in their situation over time. The 10 interviewees had a range of impairments, were gender balanced and were various ages, as well as having differing living and working situations.
