Abstract:
La Lamproie du Nord est une espèce propre à l’Amérique du Nord et elle ne se rencontre, au Québec, que dans l’extrême sud de la province. Cette lamproie a été observée dans le fleuve Saint-Laurent ainsi que dans 11 de ses tributaires. Elle aurait disparu de la rivière Yamaska où elle avait été recensée entre 1946 et 1959. Poisson non parasite, sa taille au stade adulte ne dépasse habituellement pas 160 mm. Les larves, appelées ammocètes, et les adultes ne se retrouvent qu’en eau douce. Les cours d’eau utilisés sont généralement des ruisseaux et des rivières à fond graveleux ou sablonneux. La Lamproie du Nord requiert deux habitats distincts, soit un pour les adultes reproducteurs et un autre, le long du même cours d’eau, pour le développement des ammocètes. La détérioration de l’habitat et la pollution des eaux représentent les principales menaces à la survie des lamproies. La faible fécondité et la mobilité réduite de la Lamproie du Nord font en sorte que cette espèce est peu adaptable aux modifications de son environnement.The Northern Brook Lamprey is endemic to North America. In Quebec, it is restricted to the southernmost part of the province. This lamprey is known from the St. Lawrence River as well as in 11 of its tributaries. It appears to have been extirpated from the Yamaska River where it was collected between 1946 and 1959. It is a nonparasitic fish and its adult size does not usually exceed 160 mm. Larvae, called ammocoetes, and adults are found only in fresh water. Watercourses where it occurs are generally streams and rivers with gravel or sandy bottoms. The Northern Brook Lamprey requires two types of habitats during its life cycle, one for spawning adults and one, along the same watercourse, for the developing ammocoete. Habitat degradation and water pollution are the major threats to the survival of lampreys. The low fecundity and low dispersal abilities of the Northern Brook Lamprey make this species poorly adapted to withstand changes in its environment.

Abstract:
Chondrogenesis of the trabeculae, non-collagen-based cartilages in prolarval stages of the sea lamprey, Petromyzon marinus, was examined by light and electron microscopy. Chondrogenesis of the trabecular cartilages in prolarval lampreys commenced with the formation of mesenchymal condensations. Two peaks in mesenchymal cell density occurred, one prior to condensation formation and a second immediately before cartilage differentiation. The possibility of inductive influences by epithelio-mesenchymal interactions on the initiation of chondrogenesis is discussed. Bilateral condensations first appeared by day 17 post fertilization ventromedial to the eyes in a band of tightly packed yolk-laden mesenchymal cells that represent neural crest derived tissue. Cartilage differentiation occurred by day 19 post fertilization and was indicated by the presence of matrix-synthesizing organelles and the first ultrastructural appearance in the extracellular matrix of lamprin, a structural protein unique to lamprey cartilage. Lamprin was initially deposited as discrete 15- to 40-nm globules. Subsequently, lamprin appeared as fibrils aggregated into branching and parallel arrays arranged in pericellular, territorial, and interterritorial zones. Lengthening of the trabecular cartilages was primarily by appositional growth at the rostral end. The timing of the appearance of trabecular cartilages in prolarval stages likely reflects the functional importance of these structures for supporting the brain as the lamprey initiates burrowing behaviour.

Abstract:
AbstractIn laboratory bioassays, four carabid species [Agonum dorsale (Pontoppidan), Bembidion lampros (Herbst), B. obtusum Serville, and Demetrias atricapillus (L.)] that are important predators of aphids in cereals in the United Kingdom were exposed to deposits of deltamethrin, dimethoate, or pirimicarb on glass for up to 72 h. We detected differences between compounds and species that are discussed in the context of exposure of these predators to insecticides in the field. We also describe problems involved in obtaining comparative toxicity data when dilutions of field application rates for target species are used in bioassays with nontarget species. Such problems add another dimension to risk assessment based on laboratory data.

Abstract:
We have observed seven species of predator beetles of the genus Bembidion in the agricultural landscape of the Leningrad Region (Northwestern Russia) between the years 2008 and 2018. These species reach their highest abundance in sun-exposed areas, especially mesophilic B. quadrimaculatum Linnaeus, 1761, B. properans (Stephens, 1828), B. lampros (Herbst, 1784), and B. femoratum Sturm, 1825. A few mesohygrophilic B. guttula (Fabricius, 1792) and B. gilvipes (Sturm, 1825) live primarily in areas of dense vegetation. Finally, the hygrophilic B. bruxellense (Wesmael, 1835) was only observed on the most humid soils. Assemblages of Bembidion ground beetles were separated in the fields, field boundaries, and adjacent habitats.

Abstract:
This thesis investigates the mechanical properties of the elastic proteins isolated by cyanogen bromide digestion from lamprey cartilages and compares them with the mammalian protein, elastin. Thermomechanical testing and measurements of the effects of hydrophobic solvents on mechanics are used to determine the energetic and entropic contributions to the mechanical properties and the role of solvent interactions. Raman microspectrometry is shown to be a valuable tool in determining the secondary structure of the proteins, their interactions with water and molecular-level effects of mechanical strain. The supramolecular structure of the proteins matrices are investigated using nonlinear microscopy and X-ray diffraction. The mechanical properties of fibrous elastin agreed with those previously reported with elastic moduli in the region of 0.2-0.4 MPa. Elastic moduli decrease by approximately 25% with increased temperature, which was accompanied by a small decrease in hysteresis loss. In agreement with earlier findings, an entropic mechanism of elasticity became dominant only at high temperatures with a major contribution from interactions with solvent water. The lamprey proteins can be divided into two broad groups, the 'soft' branchial and pericardial cartilages resembling elastin, with linear stress-strain behaviour over a range of strains, elastic moduli in the range 0.13 MPa to 0.35 MPa, breaking strains of up to 50% and low hysteresis. Annular and piston proteins showed a very different response having much higher elastic moduli (0.27 MPa to 0.75 MPa), higher breaking strains and large hysteresis. Similarities between elastin and the lamprey matrix proteins extended to their thermomechanical behaviour with a decrease in elastic moduli and a drive towards entropic elasticity at high temperatures, although the annulus and piston were less thermally stable. Raman spectroscopy was able to detect differences between the various proteins and between elastin fibres and fragmentation products. Although no vibrational modes associated with cross-linking of the fibres could be identified, the secondary structure of dehydrated fibrous elastin was significantly different from \alpha -elastin. The former differed from previous experimental measurements, but was close to the theoretical predictions with 36% \beta -structures, 46% unordered and 18% \alpha -helix. \alpha -Elastin contained 29% \beta -structures, 53% unordered and 18% \alpha -helix. Strains of up to 60% in ligament fibre bundles resulted in no significant shifts in peak positions or in secondary structure. Polarization measurements revealed that the peptide bonds and several of the bulky side-chains re-orientated closer to the fibre axis with strain. Heating nuchal elastin fibres to 60^{\circ} C to increase the energetic component of the elasticity was associated with a 30% increase in the proportion of \beta -structures in the amide I band, a 50% increase in the amide III band, and a 50% reduction in the signal from bound water. The Raman spectra of the lamprey matrix proteins are similar both to each other and when compared to fibrous elastin. Only small differences could be detected in side-chain modes consistent with reported biochemical differences. Decomposition of the amide I band indicated that the secondary structures were also very similar to that of elastin, with a preponderance of unordered structures which probably confer the high degree of conformational flexibility necessary for entropy elasticity. Piston and annular proteins, like elastin, showed a strong interaction with water, suggesting a greater role of hydrophobic interactions in their mechanics compared to the branchial and pericardial proteins. Elastin is well known to exhibit autofluorescence. However, only the branchial protein has been reported to autofluoresce. This study shows that all four lamprey matrix proteins investigated exhibit strong autofluorescence which was subsequently exploited to image these tissues using multiphoton microscopy. Microscopic investigations revealed that the architecture of lamprey proteins differ from that of elastin. Nuchal elastin forms bundles of fibres running predominantly parallel to the direction of applied force. The arrangement in lamprey cartilage is very different forming honeycomb structures, which in the case of annular and piston cartilages, is surrounded by a dense sheath of matrix material. Dye injections revealed that the branchial and pericardial form open systems whereas in piston and annular cartilages a closed system exists. These variations in architecture are reflected in their different mechanical properties and in vivo functions.

Abstract:
Les vertébrés font partie des animaux à symétrie bilatérale mais celle-ci n'est pas parfaite et de nombreuses asymétries sont visibles entre les côtés gauche et droit, notamment au niveau du système nerveux. L'épithalamus s'est imposé comme le modèle de référence pour l'étude des mécanismes de latéralisation du cerveau. Cette structure dérivée du diencéphale dorsal se compose de deux noyaux bilatéraux, les habénulæ et du complexe pinéal, qui regroupe les glandes pinéale et parapinéale. Les habénulæ présentent des asymétries plus ou moins marquées chez tous les grands groupes de vertébrés. La parapinéale est également asymétrique mais elle est absente dans de nombreux taxa. Chez le poisson zèbre, espèce modèle de référence pour l'étude des mécanismes de formation des asymétries épithalamiques, une migration latéralisée de la parapinéale est nécessaire à l'élaboration des asymétries habénulaires. Les mécanismes génétiques sous-jacents ont également été en partie décryptés. La première asymétrie visible dans le diencéphale dorsal correspond à une activité de la voie de signalisation Nodal à gauche. Si cette voie Nodal est essentielle pour induire une asymétrie neurogénétique précoce, elle ne l'est pas pour la formation des asymétries épithalamiques définitives. Son rôle se restreint à biaiser la directionnalité des asymétries en influençant la migration de la parapinéale. Les asymétries habénulaires sont induites par la position finale de la parapinéale. La conservation à l'échelle des vertébrés des mécanismes décrits chez le poisson-zèbre reste une question ouverte. Au cours de ce travail de thèse, j’ai cherché à comprendre l’évolution de ces mécanismes en étudiant un chondrichtyen, la roussette Scyliorhinus canicula et des cyclostomes, les lamproies Petromyzon marinus et Lampetra planeri. Leur position phylogénétique ainsi que les asymétries majeures en taille observées entre les habénulæ gauche et droite font de ces espèces de bons modèles pour comprendre leur origine chez les vertébrés. Mes travaux conduisent à trois conclusions principales :(1) on retrouve, comme chez le poisson zèbre, une expression asymétrique de la voie Nodal dans le diencéphale dorsal gauche de la lamproie et de la roussette; la directionnalité de cette asymétrie est conservée entre les trois espèces, ce qui permet d’exclure une inversion de latéralité précédemment proposée chez la lamproie sur la base d’arguments de taille relative des habénulæ(2) La voie Nodal est essentielle à la formation des asymétries habénulaires chez la roussette et la lamproie, ce qui suggère un rôle ancestral dans l’élaboration des asymétries épithalamiques.(3) une analyse détaillée des patrons de prolifération-différenciation des habénulæ au cours du développement de la roussette met en évidence des asymétries moléculaires et cellulaires multiples ; elle démontre en particulier l’existence d’une neurogenèse asymétrique qui débute plus précocement à gauche. Ces travaux donnent un éclairage nouveau sur l’origine et la diversification des mécanismes contrôlant la formation des asymétries cérébrales chez les vertébrés. L’étude de la roussette et la lamproie, deux organismes modèles non conventionnels, ouvrent de nouvelles perspectives pour leur compréhension
Vertebrates are part of the bilaterally symmetric animals but this one is not perfect and numerous asymmetries can be seen between the left and right sides, especially in the nervous system. The epithalamus has proven itself to be the model system for brain lateralization mechanisms’ studies. This structure derived from the dorsal diencephalon contains by the bilaterally paired habenular nuclei and the pineal complex, which includes the pineal gland and parapineal organ. The habenulae exhibit more or less marked left-right asymmetries among most of the major vertebrate taxa. The parapineal is also asymmetrical but it is absent in many taxa. Zebrafish is the model system for the studies of the developmental mechanisms of epithalamic asymmetries. In this species, a lateralized parapineal migration is required for the establishment of habenular asymmetries. The underlying genetic mechanisms have also been partially decrypted. The first conspicuous asymmetry in the dorsal diencephalon corresponds to a left-sided expression of components of the Nodal signalling pathway. This asymmetric Nodal signalling activity is essential to induce an early neurogenetic asymmetry but not necessary the formation of epithalamic asymmetries per se. Its role is restricted to provide a bias to the parapineal organ’s lateralized migration, and thus influence the laterality of epithalamic asymmetries. Indeed, habenular asymmetries are induced by the final position of the parapineal organ. Conservation of these mechanisms described in zebrafish across vertebrates remains an open question. During this thesis, I tried to understand the evolution of these mechanisms by studying a Chondrichthyes, the catshark Scyliorhinus canicula and cyclostomes, the lampreys Petromyzon marinus and Lampetra planeri. Their phylogenetic position and the major asymmetries in size observed between their left and right habenulae make these species good model systems to understand the origin of these mechanisms in vertebrates. My work leads to three main conclusions:(1) As in zebrafish, we have found an asymmetric expression of the components of the Nodal signalling pathway in the left dorsal diencephalon of the catshark and the lamprey. The laterality of the asymmetry is conserved between these three species, which allows us to exclude a reversed laterality in lampreys like it was proposed on the basis of arguments related to the size of habenular nuclei.(2) The Nodal signalling pathway is requied for the establishment of habenular asymmetries in the catshark and lamprey thus suggesting an ancestral role in the development of epithalamic asymmetries.(3) A detailed analysis of proliferation-differentiation patterns in the catshark habenulae during their development highlighted multiple cellular and molecular asymmetries. In particular it showed the existence of an earlier left-sided asymmetric neurogenesis.These studies provide new insights about the origin and diversification of the mechanisms controlling the establishment of vertebrates’ brain asymmetries. The study of the lamprey and the dogfish, two unconventional model systems open new perspectives for their understanding

Abstract:
Syfte: Att undersöka och jämföra effekten av olika LED-lampor genom mätning av konversionsgrad, härdningsdjup och mikro-hårdhet på en universal nano-komposit. Detta utifrån frågeställningarna: - Stämmer härdningslampornas verkliga irradians överens med den som uppges i produktdatabladen?- Kan härdningsprocessen effektiviseras genom att ljushärda med högre irradians och kortare härdningstid?Material & Metod: Materialegenskaperna - konversionsgrad, härdningsdjup och mikro-hårdhet mättes för kompositen Filtek Supreme XTE (3M ESPE) med fem LED-härdningslampor och olika härdningstider (kort, medellång, lång tid). LED-lamporna som användes i studien var L.E.Demetron II (Kerr), Mini LED (Satelec), D-Light Pro (GC), Epilar Deepcure-S (3M ESPE) och Flashmax P3 (CMS Dental). LED-lampornas spektralfördelning erhölls med en CCD-spektrometer (Avantes Inc.) kopplad till en integrerande sfär (Gooch & Housego) med en fiberoptisk kabel (Avantes Inc.). Data analyserades med ensidig och tvåsidig variansanalys (ANOVA-test) följt av Tukey-test. Resultat: En kort härdningstid och en härdning med låg irradians gav en lägre konversionsgrad, härdningsdjup och mikro-hårdhet jämfört med härdning med längre tid och hög irradians.Slutsats: Härdningslampornas verkliga irradians överensstämmer med irradiansen som uppges i produktdatabladen. En tillräcklig polymerisering uppnås med alla härdningslampor vid samtliga härdningstider. Härdningsprocessen kan effektiviseras och/eller förbättras genom att tillföra mer energi på kortare tid. Att förlänga härdningstiden utöver tillverkarens rekommendationer har en positiv effekt på materialegenskaperna – ökad konversionsgrad, härdningsdjup och mikro-hårdhet.
Aim: To investigate and compare the effect of different LED curing devices by measuring degree of conversion, curing depth and micro-hardness of a universal nanocomposite, based on the questions:- Does the actual irradiance of the curing lamps match the one specified in the product data sheets?- Can the curing process be done more efficiently by light curing with a higher irradiance and a shorter curing time?Materials & Methods: The material properties degree of conversion, curing depth and microhardness were measured for the Filtek Supreme XTE (3M ESPE) composite with different LEDs and after curing at different curing times (short, medium, long). The light curing units used in the study were L.E.Demetron II (Kerr), Mini LED (Satelec), D-Light Pro (GC), Epilar Deepcure-S (3M ESPE) and Flashmax P3 (CMS Dental). The spectral irradiance of the LEDs was obtained with a CCD spectrometer (Avantes Inc.) connected to an integral sphere (Gooch & Housego) with a fiber optic cable (Avantes Inc.). Data were analyzed with one- and two-way ANOVA test followed by Tukey test. Results: Short curing times and low irradiance results in lower values of the material properties compared to longer curing times and higher irradiance.Conclusion: The actual irradiance of the curing lamps is consistent with that stated in the product data sheets. Sufficient polymerization was achieved with all curing lamps at all curing times. The curing process can be made more efficient and/or be improved by adding more energy in less time. Extending the curing time has a positive effect on the material properties – an increased degree of conversion, depth of cure and micro-hardness.

Abstract:
Les lampes minoennes sont les seules sources de lumière artificielle à ne pas avoir été étudiées comme telles mais plutôt comme marqueurs chronologiques et régionaux. Ce travail de recherche propose une analyse fonctionnelle de ces objets, depuis la mèche jusqu’à la lumière produite et enquête, par ce prisme, sur le rythme des activités et l’espace vécu des Minoens. À cet effet, une approche interdisciplinaire a été mise en œuvre. Une analyse typo-techno-fonctionnelle a été appliquée à 543 lampes et objets ayant pu avoir un lien avec l’éclairage. Ce corpus est issu de sept sites dont la séquence chronologique couvre l’ensemble de l’âge du Bronze ; il autorise une analyse diachronique des techniques d’éclairage dans l’habitat. Le fonctionnement des lampes a été étudié dans le cadre d’un programme expérimental. Fondé sur la reconstitution du répertoire des formes, des combustibles et des mèches disponibles dans l’environnement des Minoens, il a jeté un éclairage nouveau sur les aspects techniques de leur utilisation (transport, durée de combustion, fumées, odeurs, lumière). Dans ce cadre, un référentiel de dépôts de suie a été élaboré. La forme et la texture de ces dépôts varie selon la nature des combustibles utilisés. Des enregistrements photométriques expérimentaux ont, par ailleurs, montré que les ambiances lumineuses diffèrent en fonction des combustibles utilisés. Le référentiel a donc non seulement permis d’identifier les combustibles des lampes minoennes (huiles végétales, graisses animales, cire d’abeille) mais aussi la couleur et l’intensité de leurs flammes, à partir desquels de premiers modèles en trois dimensions ont été réalisés. Une analyse spatiale des lampes dans leur contexte archéologique a, enfin, contribué à préciser le rôle de la lumière dans le rythme et la localisation des activités quotidiennes en s’appuyant, par moments, sur des analogies ethnographiques. C’est l’image d’une société préindustrielle qu’il faut avoir en tête : la journée de travail commence à l’aube et se termine au crépuscule. Son rythme et son intensité varient en fonction des saisons, de la météo et de l’altitude. Les lampes éclairaient, le soir venu, et parfois en journée, des activités collectives et individuelles, à l’extérieur ou à l’intérieur. Mais leurs flammes ne permettaient pas de voir à plus d’un mètre, ce qui suggère que l’on se déplaçait régulièrement dans le noir
Minoan lamps remain the only artificial light sources that have not yet been studied as lighting devices but rather as chronological and regional markers. This research proposes a functional analysis of these objects, entailing from the wick to the light, and investigates, through this prism, the rhythm of activities and the Minoans’ lived space. To this end, an interdisciplinary approach was developed. A typo-techno-functional analysis has been applied to 543 lamps and objects that could have a link with lighting. This corpus comes from seven settlements in a chronological sequence covering the whole Bronze Age, thus permitting a diachronic analysis of lighting techniques within the sites. The function of lamps has been studied through an experimental approach. Based on the reconstruction of shapes, fuels and wicks available in the Minoans’ environment, it has shed light on technical aspects of their utilization (transport, burning length, smokes, smells, light). In this frame, a reference database of soot deposits has been designed. These deposits’ shape and texture vary according to the fuels used. Experimental photometric recordings have, besides, showcased that light ambiances differ according to the fuels. Consequently, the reference database not only helped identifying the fuels of minoan lamps (vegetal oils, animal fats, beeswax) but also their flames’ colour and intensity, based on which some first three-dimensions models have been built. A spatial analysis of lamps in their archaeological context, eventually, contributed to define the role of light on the rhythm and the localization of activities from the daily life, sometimes thanks to ethnographic analogies. This is the picture of a preindustrial society that one shall keep in mind: work starts at dawn and ends at dusk. Its rhythm and intensity vary according to seasons, weather and altitude. Lamps lighted, from the evening onwards, and sometimes during daytime, collective and individual activities, inside and outside. However, their flames didn’t permit to see beyond one meter far, suggesting that moving in the dark was common

Abstract:
Ce travail presente les differentes phases du fonctionnement des decharges dans les gaz (lampes): le claquage, la decharge luminescente et la transition vers l'arc thermoionique. Apres avoir presente les fondements de la physique des decharges, nous analysons les differents modeles physiques et numeriques elabores pour suivre l'evolution d'une telle decharge en fonction du temps en tenant compte de plusieurs parametres: composantes du courant, densites des especes chargees (electrons et ions) et champ electrique. Nous comparons ensuite les differents modeles (monte carlo, fluide et hybride). Dans la seconde partie, nous traiterons de l'evolution temporelle de la decharge de la phase initiale de claquage dans le gaz jusqu'a la decharge luminescente a l'etat stable. La densite de courant et des particules ainsi que le champ electrique sont etudies en fonction du temps. La pression, la tension, le circuit electrique et le materiau des electrodes constituent des parametres variables. La troisieme partie est une etude bibliographique de la transition entre une decharge luminescente et un arc thermoionique. Enfin, nous exposons les resultats de trois types d'experimentations conduites en 1995 avec philips lighting (central development laboratories), eindhoven, pay bas sur des lampes. Les resultats experimentaux sont analyses pour chacune des phases de la decharge (claquage, decharge luminescente et la transition vers l'arc thermoionique) et compares aux modeles numeriques etudies precedemment

Abstract:
Today’s lighting technology is steadily becoming more energy efficient and less toxic to the environment since the passing of the Energy Independence and Security Act of 2007 (EISA) [1]. EISA has mandated a higher energy efficiency standard for lighting products and the phase out of the common incandescent lamp. This has led lighting manufacturers to pursue solid-state lighting (SSL) technologies for consumer lighting applications. However, two major roadblocks are hindering the transition process to SSL lamps: cost and quality. In order to cut cost, manufactures are moving towards cheaper packaging materials and a variety of package architecture construction techniques which may potentially erode the quality of the lamp and reduce its survivability in everyday applications. Typically, SSL lamps are given product lifetimes of over twenty years based off of the IES TM-21-11 lighting standard which does not include moisture effects or large operational temperatures [2]. A group of recently released off-the-shelf lamps have undergone a steady-state temperature humidity bias life test of 85°C/85%RH (85/85) to investigate the reliability in harsh environment applications. The lack of accelerated test methods for lamps to assess reliability prior to introduction into the marketplace does not exist in literature. There is a need for SSL physics based models for the assessment and prediction of a lamp’s lifetime which is being spearheaded by the DOE [3]. In order to be fully accepted in the marketplace, SSL lamps must be able to perform similarly to incandescent lamps in these environments, as well as live up to the lifetime claims of manufacturers. A lamp’s package architecture must be designed with performance factors in mind, as well as address some of the known and published package related failure mechanisms, such as carbonization of the encapsulant material, delamination, encapsulant yellowing, lens cracking, and phosphor thermal quenching [4]. Each failure mechanism produces the similar failure mode of lumen degradation predominately due to two contributing factors: high junction temperature and moisture ingress. The current state-of-the-art has focused on individual areas of the lamp, such as the LED chip, substrate material, electrical driver design and thermal management techniques. [5] – [16] Looking at the lamp as a whole is a novel approach and has not been seen before in literature. This work followed the JEDEC standard JESD22-A101C of 85/85 with a one hour interval of applied voltage followed by a one hour interval of no applied voltage [17]. This test was performed continuously for each SSL lamp until it became nonoperational, i.e. did not turn on. Periodically, photometric measurements were taken following the IES LM-79-08 standard at room temperature using an integrating sphere, a spectrometer, and lighting software. The overall health of the SSL lamps was assed using the relative luminous flux (RLF), correlated color temperature (CCT) and the color difference (Δu′v′) using the Euclidean distance of the CIE 1976 color space coordinates. Finally, a Weibull analysis was completed to compare the characteristic lifetime of the SSL lamp to the actual rated lifetime. An important result from this work shows that the rated lifetime does not come close to the actual lifetime when the SSL lamps are used in a harsh humid environment which is fairly common in outdoor applications across the U.S. Also, the photometric results are presented for the entire lifetime of each SSL lamp under test.

Abstract:
It mainly discusses the application of virtual reality technology to the conical roof lifting for the AP1000 nuclear power plant. By choosing the sketch-up and AutoCAD soft-wares, this paper established the 3d models of the conical roof and the 2600T Lampson crane in the manner of parameter. Based on virtual construction theory, these 3 d models were used to implement the simulation tests for the whole lifting progress in virtual environment so as to obtain optimized construction scheme and to train crane operator. And also the optimum running track for the crane is provided by the analysis, and the most economical enlargement plan for the 2600T Lampson crane landing pad is also provided.

Abstract:
Various lamps have been used by spectroscopists to study the electronic structure of their respective species. Two of the more common lamps in use are Electrodeless Discharge Lamps (EDLs) and Hollow Cathode Lamps (HCLs). Microwave and radiofrequency excited EDLs have temperatures in the 400-600 K range, pressures in the 0.1-10 torr range and a common excitation frequency of 2450 MHz. The maximum power is 150 W. They are constructed from quartz tubing measuring 10 mm in diameter and 30 mm in length. HCL's are typified by low gas temperatures (400-500 K) and low pressures (0.1-10 torr). Both EDLs and HCLs are produced commercially.
