Der volle Inhalt der QuelleA calandra hidráulica é uma máquina industrial concebida para con- formação de chapa. Nos dias de hoje é uma máquina muito comum na indústria metalomecânica, para fabrico de caldeiras e torres eólicas. Neste trabalho foi desenvolvido um sistema de comando numérico com- putorizado (CNC) com objectivo de modernizar o sistema de controlo da calandra de accionamento hidráulico. Para implementação da solução final foi necessário definir uma base de hardware e uma base de software para controlo do processo. No sis- tema desenvolvido foi implementado uma rede suportada no protocolo RS485 de autómatos programáveis (denominados de PLCs, do inglês "Programmable Logic Controllers") baseada numa arquitectura mestre escravos (master and slaves) que estão directamente ligados aos actu- adores e sensores usados na estrutura, no topo da pirâmide de controlo encontra-se um computador industrial que têm com funções principais o supervisionamento do processo de controlo, calculo numérico e in- terface com o utilizador. O sistema de comando desenvolvido têm dois modos de trabalho, um modo automático e outro o modo manual. No modo manual a máquina ¶e accionada directamente pelos botões e joystiks do painel de comando, sendo sempre possível ao operário basear-se no sistema de sete eixos de controlo implementados na máquina.

Der volle Inhalt der QuelleThe objective of this thesis is the study of the reception of the staging and translation of Cardinal Bibbiena’s La Calandra in France from the 16th to 19th centuries. It firstly explores how this play was received in France, then seeks to understand how its licentious comedy, taken from the living language of the stories of Decameron, was conveyed in the 19th century French translations. Through examination of the work’s first performance in Urbino in 1513, then Lione’s 1548 version, it subsequently seeks to demonstrate how the comedy of the dialogue was communicated in the two French translations: the first by Theodore Muret in 1835 and the second by Alcide Bonneau in 1887. The process of the reception of La Calandra in the centuries examined, which resulted from rich and varied phenomena, is evidenced in detail

Der volle Inhalt der QuelleProcurou-se determinar se a distribuição dos machos de Trigueirão {Miliaria calandra) obedece a algum padrão relativamente a vários tipos de biótopos agrícolas (seara, pousio e olival), e se diferentes densidades de machos territoriais têm algum efeito na sua actividade de canto. O trabalho de campo decorreu durante as épocas reprodutivas de 1997 e 1998, na região de Castro Verde (Baixo Alentejo). Verificou-se não existir nenhuma associação significativa entre qualquer dos biótopos considerados e a densidade de machos com território estabelecido. Alterações na utilização do terreno entre os dois anos não foram acompanhadas por alterações na densidade das aves. A taxa de canto (número de cantos/minuto) não apresenta uma variação entre áreas de alta ou baixa densidade, mas varia significativamente entre os dois anos de estudo. A actividade de canto é maior em áreas com maior densidade de machos territoriais, mas apenas quando se considera a percentagem de minutos em que os indivíduos cantaram.

Der volle Inhalt der QuelleO presente trabalho apresenta o desenvolvimento de uma metodologia para transformar calandras de tubos e chapas convencionais em equipamentos com sistema automático programável para execução de peças com raios fixos e/ou variáveis. É apresentado um projeto mecânico conceitual (sem detalhamento) e são implementados recursos computacionais para reconhecimento de desenhos definidos em sistema de projeto auxiliado por computador com o objetivo de gerar automaticamente o programa-tarefa capaz de executar a conformação da peça projetada. Desta maneira, o requisito de operação programável é satisfeito fazendo com que o equipamento trabalhe segundo os princípios de máquinas CNC. A proposta considera ainda o ajuste necessário nos parâmetros de operação da máquina devido a recuperação elástica do material através do processamento de uma imagem extraída de uma foto da peça conformada. Desta forma, o raio executado na peça é reconhecido e torna-se possível compará-lo com o raio projetado. Conforme demonstra o estudo, para análise da viabilidade técnica da proposta, o sistema foi implementado na forma de aplicativo de sistema CAD e conclui-se ser viável, já que a metodologia de programação foi implementada com sucesso e gerou resultados satisfatórios, onde o usuário desenha uma peça em sistema CAD e um programa CNC para a execução da peça é gerado. Outros aspectos relativos e importantes para o desenvolvimento da metodologia são discutidos, tais como: programação CNC, processamento de imagens, programação em sistemas CAD e processo de conformação mecânica para curvar tubos ou chapas.

Der volle Inhalt der QuelleThe steam generator is one of the major components of the power generation unit for the propulsion of Naval Group ships. The physical phenomena involved in these heat exchangers are complex to simulate because of the variety of flow patterns and heat transfer regimes. This thesis aims to develop a program adapted to the modeling of Naval Group’s steam generators. The developed methodology proposes a coupling between a 1D-code and CFD calculation based on the porous media approach. The modeling of monophasic flows within heat exchangers is first discussed before presenting that of two-phase flows. The method’s interest is highlighted by its validation on experimental test cases and by comparing it to other existing numerical approaches. The work brings solutions to model helically coiled steam generator and allow to consider the simulation of more complex geometries. The calculation of the hydraulic forces and energy exchanges between the liquid, the vapor and the tube’s wall is detailed. By its structure, the model tends to be able to represent all possible configurations of steam generators. Different ways of feeding this model are proposed to replace the existing empirical laws and make it possible to envisage new and more adapted solutions

Der volle Inhalt der QuelleLes résultats montrent que (1) les mâles aux yeux rouges (R) et les mâles aux yeux foncés (W) sont différents dans leur capacité d'accouplement mais que les femelles R s'accouplent indifféremment avec les mâles des deux phénotypes. (2) Le comptage des spermatozoïdes dans les vésicules séminales des mâles vierges de 1 jour montre que les mâles R ont environ 1,46 fois plus de spermatozoïdes que les mâles W (4545 vs 3116). Les mâles expérimentés ont seulement 15% à 25% du stock initial d'un mâle vierge du même âge. Un mâle vierge de 21 jours a environ 1,8 fois plus de spermatozoïdes qu'un mâle vierge de 1 jour dans les deux morphes. (3) Après un accouplement simple des mâles, les nombres moyens de spermatozoïdes stockés dans la spermathèque des femelles ne sont pas différents entre eux (en moyenne 143 spermatozoïdes). (4) Les femelles réalisant des accouplements doubles n'augmentent pas leur stockage spermatique (193 spermatozoïdes pour deux accouplements vs 161 pour un), ni leur fécondité (respectivement 130 vs 108 descendants). (5) Un accouplement est suffisant pour assurer leur fécondité durant la vie reproductive des femelles et la sex-ratio est biaisée en faveur des femelles (environ 0,79). Les femelles accouplées avec les deux mâles de morphes différents produisent des descendants des deux phénotypes durant leur vie reproductive, quel que soit l'ordre des mâles dans la séquence de copulation. (6) Après une compétition entre deux mâles différents par leur phénotype, par leur âge ou par leur expérience sexuelle, c'est toujours le mâle ayant le plus de spermatozoïdes dans les vésicules séminales qui est le plus représenté dans la descendance quelle que soit la combinaison d'accouplement. Ces résultats concernant la paternité des descendants après une compétition entre deux mâles correspondent parfaitement à une loterie honnête, « fair raffle » proposée par Parker en 1990. (7) Quant à la quantité de spermatozoïdes transférés à la femelle, aucune augmentation ni diminution n'a été mise en évidence contrairement à ce qui est prédit par les théories concernant le risque de compétition spermatique ou l'intensité de compétition spermatique.

Der volle Inhalt der QuelleThe male fitness (reproductive success) means by mating number and offspring obtained by mate (Dewsbury, 1982; Simmons, 2001). It depends on the number of spermatozoa that succeed in egg fertilization. In competition, a male should optimize his reproductive success according to rivals. Through multiple mating of a female insect, sperm competition may occur between ejaculates of different males in female sperm store(s). Study tool of sperm competition is mainly the determination of offspring paternity. A recessive mutant of eye colour (red eyes) was used to investigate the differences in male mating capacity and fertilization success in the parasitoid wasp Anisopteromalus calandrae (Hymenoptera, Chalcidoidea, Pteromalidae). This work concerned the study of male reproductive success in relation to their available sperm supplies. First, the quantification of male sperm supply was performed in function of male life history (age or mating history) and phenotype. Second, the relationship between male reproductive success and sperm supply was examined through single mating, multiple mating and after competition between two males. Consequences of female double matings on the offspring paternity of males having different statuses (either young, aged, or with sexual experience) was measured by the use of this paternity genetic marker (eye colour). Experimentally, results showed that (1) red-eyed (R) and wild-eyed (W) males are different in mating capacity but females mate normally with males of both phenotypes. (2) Sperm count in seminal vesicles evidenced that one-day-old R virgin males have more sperm than W ones (approximately 1. 46 times greater, 4545 vs 3116 spermatozoa). Experienced males have only 15% to 25% from the initial sperm store of virgin males. 21-days-old virgin males have 1. 8 times more sperm than one-day-old ones in both morphs. (3) The number of sperm stored by females in spermatheca after one mating does not differ (143 spermatozoa in average). (4) Double-mated females increase neither sperm storage (193 spermatozoa after double mating vs 161 after single) nor fecundity (respectively 130 vs 108 offspring). (5) One mating ensures life-time fecundity of females, and offspring sex ratio is anyway female-biased (about 0. 79). Double mated females with two males of different phenotypes produce offspring of both phenotypes, whatever the mating order of males. (6) In competition of two males, any mating pattern always produce more offspring of the male having more sperm in seminal vesicles, whatever the male phenotype, age or mating history. In Anisopteromalus calandrae, offspring paternity distribution (after female double matings) is consistent with a fair raffle process of sperm from both donors, proposed by Parker in 1990. (7) Finally, results do prove neither augmentation nor diminution of transferred sperm quantity by males to females, opposed to sperm competition risk or intensity theories

Der volle Inhalt der QuelleWithin a worldwide energy transition, the enhancement of electricity production systems plays a keyrole. Thus, the optimisation of these systems, or their constitutive components, aims at improving their efficiency, in order to better convert a energy source into electricity. In particular, it covers Rankine cycles, that numerous studies deal with, focusing on improving their performance rating. The current study is only about a single component of this steam cycle : the condenser, which is charged of condensing steam at the ouput of the turbine. A numerical modelling of the condenser has been carried out, in order to characterize its thermal and hydraulic performances. It involves an homogenization method, the porous media approach, to asses the thermal transfer, in the case of a shell-and-tube heat exchanger. To do so, each constitutive component of this model is described and validated. The main innovative aspects of this model are its increased precision, since it can give information about each tube’s performance, and the correlations’ combination, which choice is based upon a bibliographic study. With the reached precision, the model enable the user to improve the local performances of the heat exchanger

Der volle Inhalt der QuelleParasitoids develop at the expense of a host. In solitary species, because of lethal larval fights, only one adult can emerge from a given host, whatever the number of eggs initially laid. The aim of this PhD is to study oviposition strategies of females of a solitary species, Anisopteromalus calandrae, under intraspecific competition conditions. Our results show that females of this species can discriminate different categories of hosts (unparasitized / parasitized, parasitized for different times and parasitized by a male or a female egg), partly due to chemical signals originally from the hosts. They consequently adjust their oviposition strategies, according to both the survival probability of their offspring and their own physiological state

Der volle Inhalt der QuelleIncludes bibliographical references (leaves 113-115).
The ACR-700 is an advanced pressure-tube (PT) reactor being developed by Atomic Energy of Canada Limited (AECL). As in conventional CANDU reactors, the PTs are horizontal. Each PT is surrounded by a calandria tube (CT), and the gap in between is filled with carbon dioxide gas. The space between the CTs is filled with the heavy-water moderator. One postulated accident scenario for ACR-700 is the complete coolant flow blockage of a single PT. The flow is not monitored within each individual PT, thus during the early stages of this accident the reactor remains at full power and full pressure, resulting in rapid coolant boil-off and fuel overheating. Melting of the Zircaloy (Zry) components of the fuel bundle (cladding, end plates and end caps) can occur, with relocation of some molten material to the bottom of the PT. The hot spot caused by the molten Zry/PT interaction may cause PT/CT failure due to localized plastic strains. Failure of the PT/CT results in depressurization of the primary system, which triggers a reactor scram, after which the decay heat is removed via reflooding, thus PT/CT rupture effectively terminates the accident. Clearly, prediction of the time scale and conditions under which PT/CT failure occurs is of great importance for this accident. We analyzed the following key phenomena occurring after the blockage: (a) Coolant boil-off (b) Cladding heat-up and melting (c) Dripping of molten Zircaloy (Zry) from the fuel pin (d) Thermal interaction between the molten Zry and the PT (e) Localized bulging of the PT (f) Interaction of the bulged PT with the CT Simple one-dimensional models were adequate to describe (a), (b) and (c), while the three-dimensional nature of (d), (e) and (f) required the use of more sophisticated models including a finite-element description of the thermal transients within the PT and the CT, implemented with the code COSMOSM.
(cont.) The main findings of the study are as follows: (1) Most coolant boils off within 3 s of accident initiation. (2) Depending on the magnitude of radiation heat transfer between adjacent fuel pins, the cladding of the hot fuel pin in the blocked PT reaches the melting point of Zry in 7 to 10 s after accident initiation. (3) Inception of melting of the UO2 fuel pellets is not expected for at least another 7 s after 2Zry melting. (4) Several effects could theoretically prevent molten Zry dripping from the fuel pins, including Zry/UO2 interaction and Zry oxidation. However, it was concluded that because of the very high heat-up rate typical of the flow blockage accident sequence, holdup of molten Zry would not occur. Experimental verification of this conclusion is recommended. (5) Once the molten Zry relocates to the bottom of the PT, a hot spot is created that causes the PT to bulge out radially under the effect of the reactor pressure. The PT may come in contact with the CT, which heats up, bulges and eventually fails.
(cont.) The inception and speed of the PT/CT bulging and ultimately the likelihood of failure depend strongly on the postulated mass of molten Zry in contact with the PT, and on the value of the thermal resistance at the Zry/PT interface. It was found that a Zry mass =/< 10 g will not cause PT/CT failure regardless of the contact resistance effect. On the other hand, a mass of 100 g would be sufficient to cause PT/CT failure even in the presence of a thick 0.2 mm oxide layer at the interface. The characteristic time scales for this 100-g case are as follows: PT bulging starts within 3 s of Zry/PT contact - PT makes contact with the CT in another 2 s - CT bulging starts in less than 1 s - CT failure occurs within another 5 s. Thus, the duration of the PT/CT deformation transient is 11 s, which gives a total duration of the accident (from PT blockage to PT/CT failure) of 18 to 21 s.

Der volle Inhalt der QuelleCalendering consists of running a sheet of paper at high pressure and speed (contact time less than 1 ms) between at least two heated rolls so as to improve the paper surface quality. However, this operation reduces paper thickness. Our study focused on the mechanical behaviour of paper in the nip and on the surface interactions between the paper and the rolls. Different grades of printing and writing paper were studied (coated, un-coated). Two spherical indentation tests on paper samples were developed (falling ball and quasi-static compression) and calendering trials were performed. The contact time in the falling ball test is equivalent to that in calendering. The mechanical interpretation of these tests and trials allows us to obtain stress / strain curves and the evolution of « static » elastic modulus with the permanent deformation. The mechanical variables are influenced by the paper formulation, conditioning and time of solicitation. Using the quasi-static compression test, a model permits to evaluate the nip width in static conditions. The adhesion between the paper surface and the rolls is studied with a rolling friction test and calendering trials. Calendering trials enable to link the improvement of paper surface properties (gloss, smoothness) to the thickness reduction and to specify how the roll surface roughness is transferred onto the paper

A principal forma de controle de Rhyzopertha dominica (Fabricius), em grãos armazenados, é através do uso de inseticidas, apesar de existirem relatos de resistência a esses produtos, em populações dessa espécie. Neste sentido, a utilização do manejo integrado de pragas (MIP) é uma alternativa para preservar os ingredientes ativos existentes, assim como reduzir os resíduos de inseticidas nos produtos armazenados. No Brasil, o uso do controle biológico como ferramenta do MIP em armazéns ainda não é utilizada, embora pesquisas já demonstrem sua eficiência e compatibilidade com os principais métodos de controle. Um importante inimigo natural vem se destacando na supressão populacional de pragas de grãos, o ácaro Acarophenax lacunatus (Cross & Krantz), que parasita os ovos de seus hospedeiros. Este estudo teve como objetivo principal avaliar a interação desse parasita com o inseticida deltametrina, a temperatura e o parasitóide de larvas Anisopteromalus calandrae (Howard), considerados os principais métodos de controle químico, físico e biológico de R. dominica, respectivamente. Antes de analisar a eficácia dessas interações, foi avaliada a utilização de um acaricida para controlar as infestações indesejadas de A. lacunatus. O parasita A. lacunatus demonstrou ser uma importante ferramenta para MIP de grãos armazenados, uma vez que foi possível sua associação com os principais métodos de controle de R. dominica, com exceção do uso do dobro da dose de deltametrina recomendada (1,00 mg i.a./kg). Por outro lado, em doses menores do que 1,00 mg i.a./kg de deltametrina, o A. lacunatus demonstrou-se eficaz na redução das fases imaturas desse inseto-praga. O parasita A. lacunatus, quando associado a temperaturas da massa de grãos mais baixas, apresentou sua eficácia potencializada. Do mesmo modo, isso também foi observado quando esse ácaro foi associado ao parasitóide de larvas A. calandrae melhorando sua eficácia. Estes resultados reforçam a importância de A. lacunatus como uma alternativa para a redução dos níveis de inseticidas necessários ao controle das infestações de R. dominica sobre grãos.
The main control method of Rhyzopertha dominica (Fabricius) in stored grains is by insecticide use despite of the existing reports of insecticide resistance in population of this species. The use of integrated pest management (IPM) is therefore and alternative to preserve the existing active ingredients and to reduce insecticide residue in stored products. The use of biological control is not get used as an IPM component in Brazil, although some studies demonstrate its efficiency and compatibility with the main control methods. An important natural enemy is coming to focus is the suppression of grain pests populations, the mite Acarophenax lacunatus (Cross & Krantz), a host egg parasite. This study aimed to assess the interaction of this parasite with the insecticide deltamethrin, the temperature and the larvae parasitoid Anisopteromalus calandrae (Howard), considered the main chemical, physical and biological control agents of R. dominica, respectively. Before assessing these interactions, the use of an acaricide to control undesirable infestations of A. lacunatus was carried out. The parasite A. lacunatus showed to be an important tool for stored grains IPM since was possible its association with the main control methods for R. dominica, with the exception of twice the recommended deltamethrin dose (1.00 mg a.i./kg). In contrast, A. lacunatus was effective in reducing immatures of this pest-species in deltamethrin doses lower than 1.00 mg a.i./kg. The parasite A. lacunatus showed increased efficacy when associated with lower temperatures of the grain mass. The same was observed when associated with the larvae parasitoid A. calandrae. The results reinforce the importance of A. lacunatus as or alternative to reduce the insecticide levels necessary to control R. dominica infestations on grains.

Der volle Inhalt der QuellePrinting quality idea is hard to control. In industry, eye is often used to judge the quality of a printed polymer film. In order to get a new level in terms of printing quality and get “point by point” or “all-over” quality, it is necessary to find a way to quantify printing quality. Some elements are important concerning the quantification of the printing quality: an optical microscopic image, a value of the average intensity and a value on the homogeneity of the color. We can define, for a calendered and a coated substrate, the main parameters acting on the printing quality. Printing speed and pressure of the rubber roll are the two main process parameters to act, viscosity and surface tension of the ink are the two main ink properties to act, while the calendered substrate is more sensitive to the variation of the parameters than the coated one

Der volle Inhalt der QuelleIn parasitoids wasps, reproductive success not only perpetuation of the species, it is also a very important factor for biological control against pests, since it is essential that the population grows and sustainably produce fertile offsprings. During their lives, because of their small size, parasitoids face ecological constraints (both biotic and abiotic) that may affect directly or indirectly the individuals, involving changes in their morphology, physiology or behavior, which in turn, affect the survival and reproductive success. The overall objective of this thesis was to better understand the consequences of the ecological constraints on reproduction in the ectoparasitoid wasp Anisopteromalus calandrae. Our results show that the parasitoid females’ decision to lay eggs is related to the host density that affects both the offspring’s size and fitness, consequently increasing the number of males in the offspring. On the other hand, the thermal stress applied to the pupae or adults had negative effects on survival and decreased the quantity of sperm. Moreover, stressed males are less successful competitors

Der volle Inhalt der QuelleBased on industrial experience of UPM mills and advanced pulp and paper analysis, this thesis has aimed to clarify the potential and limitations of recycled fibres (RCF) for Super Calendered (SC) magazines and recommend future developments in fibre processing technology. RCF is found to improve SC print density and evenness in Rotogravure but tends to deteriorate light scattering, print through, calender blackening and missing dots. The origin of the differences observed between virgin fibre and RCF based SC has been studied by simulating the effects of fibre composition, recycling and refining stages on SC paper quality. Chemical fibres content turns out to be a parameter driving most of SC characteristics, including print through and calender blackening. Conversely, the presence of coarse mechanical fibres within RCF was found to have a marginal effect on SC paper quality. Finally, the trend for more missing dots when printing RCF compared to virgin fibres based SC originates at least partially from high energy RCF refining

O uso de substâncias psicoativas sempre esteve presente na história da humanidade, porém, devido ao crescente e precoce consumo transformou-se em problema mundial de Saúde Pública, gerando em todas as partes do mundo importantes questões sociais e de saúde, exigindo medidas de enfrentamento que implicam, entre outras, não só a identificação da prevalência, mas também o aprofundamento compreensivo das experiências dos atores envolvidos no processo. Entre estes fatores considerou-se, neste estudo, o papel dos professores, no acompanhamento destas crianças em ambiente escolar, entendendo a escola como um espaço em que criança e adolescentes permanecem diariamente e por longos períodos construindo e desenvolvendo, entre outras coisas, suas normas de comportamento e convivência sociais. O estudo foi realizado com 32 professores de três escolas públicas estaduais da cidade de Penápolis, SP, lotados em duas escolas periféricas e uma central, objetivando: compreender a interação do professor da rede pública com aluno usuário de substâncias psicoativas e desenvolver modelo teórico representativo desta experiência. Pesquisa conduzida nos padrões da Declaração de Helsinque, aprovada pela comissão de ética UNESP-Araçatuba. Referencial teórico Interacionismo Simbólico. Referencial metodológico Grounded Theory. Técnica de coleta de dados grupos focais. Foram identificados três fenômenos: Identificando os alunos usuários de substâncias psicoativas: ouve rumores; percebe manifestações relativas ao uso; observa o aluno assumindo condição de usuário, pondera sobre fatores protetores e indutores ao uso.

Der volle Inhalt der QuelleThis PhD thesis deals with the understanding of the heat transfer mechanisms and with the development of thermal energy storage system for the industrial waste heat recovery application. The use of Phase Change Materials (PCM) is attractive for its high storage density and its possibility to deliver heat at constant temperature. However, the PCM low thermal conductivity leads to develop heat transfer improvement methods, such as heat exchangers with increased heat transfer surface. The goal is to characterize the behavior of such heat exchangers An experimental study, where four several heat exchangers have been tested with different orientations (horizontal/vertical) and injection types (upward/downward), highlighted the impact of natural convection during the melting process and the volume contraction one during the solidification. These results have been validated through a 3D numerical model. A performance comparison method based on an energy calculation through an experimental mesh is proposed and enables to select a heat exchanger on criteria such as the storage density, the characteristic time and the cost. Three PCM, adapted to our application, have been tested at the intended temperature (100-200 °C) by integrating them into a storage system made of a stainless steel tube with aluminum circular fins. Their ability to resist to repeated cycles has been assessed and their behavior has been compared. The salts mixture, H105 (Tmelting = 122 °C), is not selected for the application because of it low storage density (≈ 56 kWh/m3) and its large melting area. The sebacic acid (Tmelting = 132 °C) has a repeatable behavior with cycles and a higher storage density (≈ 66 kWh/m3) and is appropriate as storage material. The sugar alcohol, erythritol (Tmelting = 118 °C), has good thermo-physical properties (128 kWh/m3) but the crystallization control is a key point to use it as a PCM

Der volle Inhalt der QuelleThe Nile Mosaic of Palestrina( ancient Praeneste), dating from about 150-100 B.C., is a large mosaic pavement depicting the course of the river Nile during the inundation season. The Nile Mosaic originally formed the floor of the "Aula Absidata" in Praeneste's ancient Forum. Recordered in 1614 by Federico Cesi, it spread among many antiquaries and Lincei, including Cassiano Dal Pozzo and Cardinal Francesco Barberini. The nineteen coloured copies of Nile Mosaic, commissioned by Cassiano for the Paper Museum, were probably executed by Vincenzo Leonardi; the drawings were greatly celebrated and served as the basis for every restoration work.
