Profibus and CAN bus are two kinds of widely used field bus in the industrial control field. However, this two bus protocol conversion devices are not introduced on the market, it can not meet the needs of users. Therefore, the design of a Profibus and CAN protocol translation ngateway is very important. By comparing the OSI reference model, the same points of Profibus and CAN bus can be found, their communication model structure is streamlined by the OSI model, they are only three layers, which makes it possible to interconnect them. This paper designs an embedded protocol conversion gateway, S3C2410 processor is used as main controller, SPC3 and SJA1000 are selected as Profibus and CAN protocol chips. The design has realized Profibus and CAN bus protocol conversion, using this gateway in industrial field can bring certain economic benefits for the enterprise.

With the application of digital information technology and communication technology, industrial intelligence and integration also began to develop rapidly, and the importance of the research on bus communication in industrial control communication also increased. As the first international bus standard, PROFIBUS has been widely used in the field of industrial control; in recent years, it was mainly used to connect devices to the control layer and convert data through token transmission. Based on the understanding of the transmission mechanism of PROFIBUS fieldbus protocol, this article carries out a simulation study on its communication performance. Through analysis of the data link layer, changing the target token cycle time (high and low priority) and random setting each site message number, as well as the number of master station and slave station, how the main token latency and packet loss rate and efficiency of bus affect the change of performance parameters was observed. For multiple communication systems, the relationship between the address value on the main token ring and transport performance is found by experiments on the site address value on the main token ring and the target token cycle time value. Finally, the scheduling algorithm is applied to the communication scheduling of PROFIBUS fieldbus. The results confirm that the scheduling algorithm has better transmission efficiency than the traditional MAC media access protocol under the condition that the load rate does not exceed 100%, which makes up for the shortcomings of the original PROFIBUS bus system and makes the communication performance better.

Traditional elevator indicators have been improved for traditional elevator indicators with strict communication requirements, high communication costs, and unsuitable for fieldbus-guided industrial production. That is, the PROFIBUS-DP interface is developed for the traditional hoist multi-level indicator, and the bus bridge is used to complete the communication protocol conversion during the data transmission process, so that it can be added to the field bus production system. This paper deals with the design of the multi-level indicator hardware circuit of the hoist with PROFIBUS-DP interface and the design of the software circuit. Finally, the system test platform was built to verify that the hoist indicator structure is simple and reliable.

In control technique there is evident highly expressive trend of shifting from efficient central managing systems towards smaller systems which are distributed on technology and which are connected by communication bus. There is no need to link all signals to central management system, operation is then distributed and realized directly in individual parts of technology. That’s why these systems are called distributive managing systems. Distributive managing systems are widely used not only in industrial applications but also in buildings, cars, etc..

Les espèces exotiques envahissantes et les maladies infectieuses représentent un problème croissant au niveau mondial et constituent l'une des principales menaces pour la biodiversité. La Nouvelle- Calédonie, archipel situé dans le sud-ouest du Pacifique, est reconnue comme l'un des principaux points chauds de la biodiversité. Sa flore vasculaire native illustre cette singularité biologique remarquable, avec 3250 espèces dont plus de 74% sont endémiques. Dans ce contexte, la gestion et la préservation de cette biodiversité est une question prioritaire. Austropuccinia psidii est un champignon, considéré comme l’une des principales menaces environnementales pour les plantes appartenant à la famille des Myrtaceae à l’échelle mondiale. Communément connu sous le nom de "rouille des Myrtaceae", ce pathogène a été observé en Nouvelle-Calédonie en 2013. L’établissement de ce phytopathogène exotique est préoccupant compte tenu de l’importance environnementale occupée par les Myrtaceae dans les écosystèmes de l’archipel. L’objectif appliqué de cette thèse est de mettre en place une stratégie de lutte permettant à la fois de contrôler l’expansion du pathogène en milieu naturel, et dans[ les ]pépinières productrices de Myrtaceae.Dans une première partie, nous allons mettre en évidence l’importance de l’impact d’A. psidii en termes d’étendue géographie, de gamme hôte et de sévérité des symptômes induits. Ces informations sont primordiales pour cibler spécifiquement les priorités de conservations des espèces et préservation des milieux les plus touchés. Les résultats montrent qu’A. psidii impacte un large panel d’espèces de Myrtaceae sur le territoire. Les variations dans la sévérité des symptômes exprimés entre individus d’une même espèce suggèrent la possibilité d’engager une lutte intégrée axée sur la sélection de caractères liés à la résistance à cette maladie.Dans une seconde partie, nous tenterons d’identifier des marqueurs génétiques permettant de discriminer les individus en fonction du phénotype de résistance qu’ils expriment face à l’infection causée par la rouille. C’est ainsi que via une approche RNA-Seq, combinant à la fois une analyse de différentiel d’expression des gènes et la recherche de variants nucléotidiques directement positionnés sur des parties codantes des génomes de plantes concernées, nous sommes parvenus à identifier des gènes candidats discriminants pour les caractères résistants vs sensibles chez des espèces de Myrtaceae locales connues pour leurs caractères patrimonial, économique, ou encore écologique. Parmi ces gènes candidats certains admettent des fonctions connues impliquées dans les mécanismes de résistance aux pathogènes
Invasive alien species and emerging infectious diseases represent a growing worldwide problem and constitute one of the major threats to biodiversity. New Caledonia, an archipelago located in the South West Pacific, is recognized as one of the major biodiversity hotspot. The native vascular flora illustrates this outstanding biological uniqueness, with 3250 species of which over 74 % are endemic. In this context, management and preservation of this biodiversity is a priority issue.Austropuccinia psidii is a fungus considered to be one of the major environmental threats to plants belonging to the family Myrtaceae on a global scale. Commonly known as "Myrtle rust", this pathogen has been observed in New Caledonia in 2013. The establishment of this exotic plant pathogen is of concern given the environmental importance of Myrtaceae in the archipelago ecosystems of Myrtaceae.The objective of this thesis is to put in place a strategy to control both the expansion of the pathogen in a natural environment and in nurseries cultivating Myrtaceae.In a first part, we will highlight the importance of the impact of A. psidii in terms of geographic extent, host range and severity of symptoms. This information is essential to specifically target the conservation priorities of the species most affected and preserved their habitats. The results show that A. psidii impacts a wide range of Myrtaceae species on the territory. Variations in the severity of the symptoms expressed between individuals of the same species suggest the possibility of initiating integrated control strategy based on the selection of traits related to resistance to this disease.In a second part, we will try to identify genetic markers to discriminate individuals according to the phenotype of resistance they express to the infection caused by myrtle rust. By using an RNA-Seq approach, combining both differential gene expression and the search for nucleotide variations positioned in coding parts of the genomes, we were able to identify discriminant candidate genes for resistant vs susceptible in endemic Myrtaceae species known for their patrimonial, economic or ecological role. Among these candidate genes some admit known functions involved in mechanisms of resistance to pathogens

Cette étude fut réalisée grâce à la collaboration entre l'université du Québec à Montréal (UQAM) et l'université de Nouvelle-Calédonie (UNC). Cette thèse avait pour objectifs de parfaire nos connaissances sur l'ensemble des éléments géologiques du massif ophiolithique de Koniambo en Nouvelle-Calédonie ainsi que sur les conditions géodynamiques de mise en place. La distribution des éléments d'intérêt économique (nickel, cobalt et scandium) dans les faciès d'altération superficiels de l'ophiolite fut aussi étudiée. L'enchevêtrement des diverses unités géologiques présentent dans la zone d'étude suggère un assemblage imbriqué formant une suite structuralement inversée dont certains membres ultramafiques ont été fortement affectés par leur passage en milieu supra-subductif (SSZ). Cette disposition structurale inverse est décrite pour la première fois en Nouvelle-Calédonie et contraste avec les séquences ultramafiques moins démembrées du sud de l'île. Les analyses chimiques des divers faciès du profil latéritique du Koniambo ont démontré que ceux-ci sont non seulement riches en nickel et cobalt mais aussi en scandium. Nos travaux ont permis d'identifier certains niveaux d'enrichissements en scandium dans les phases minéralogiques des altérites. La problématique de la représentation tridimensionnelle de la distribution des faciès constitutifs des profils fut étudiée. Il est proposé une méthodologie de modélisation tridimensionnelle qui met en oeuvre les principes de géostatistiques tels que le kriging pour l'interpolation des blocs en milieu déridé (unwrinkling) ainsi que le concept de changement de support afin d'adapter le modèle à la sélectivité minière envisagée.

For the Arid Shrublands of Western Australia (WA) knowledge is limited on what sheep eat and how nutritious their diets are. A study was undertaken on two stations near Yalgoo (28º18’S 116º38’E) in WA, from November 2005 to December 2007. Station 1 (28º39’S 116º18’E) used a flexible rotational grazing management system (RGS), moving 3000-4000 Merino sheep every 3 – 6 weeks through a choice of 20 paddocks. Station 2 (28º18’S 116º42’E) used a flexible continuous grazing management system where small mobs (500 sheep) stayed in paddocks all year, until shearing. Two paddocks on Station 2 were chosen to represent paddocks with high (CGS-G) and low (CGS-P) feed value.A total of 300 Merino hogget (18 months old) ewes were randomly selected from the stations. One hundred and fifty sheep from each station were selected and separated into three mobs of 50 sheep by stratifying live weights. The selected sheep were allocated to either of the two paddocks on Station 2 or the single rotating mob on Station 1. Therefore there were a total of 100 sheep, 50 from each station, on each of the two paddocks on Station 2 and the one rotating mob on Station 1.Throughout the study period sheep live weights, body condition scores (BCS) and wool production were measured and related to plant photosynthetic activity (derived from Normalised Difference Vegetation Index - NDVI), and dietary energy, protein and digestibility (determined from faecal NIRS calibrations). A DNA reference data bank of some common native plant species was established and then used as a library to identify plant species in sheep faeces and thus provide information on variations in diet composition over the study period. Plant nutritional content was also measured and compared to climatic changes and sheep nutrition.Over the study period Merino ewe live weights, wool production, faecal samples and native plant leaf material were collected and analysed from each of the three management treatments (RGS, CGS-G, CGS-P). Wool production measurements included wool length, strength and fibre diameter, including position of breaks, minimum and maximum diameter along the staple of midside samples. Oven dried plant and faecal samples were ground and subsequently analysed for proximate composition. Plant samples were further analysed for mineral contents and 24 h in vitro gas production (GP) using the rumen buffer gas fermentation technique. Organic matter digestibility (OMD) and metabolisable energy (ME) content of the plants were determined using 24 h net gas production. Faecal near infrared reflectance spectroscopy (fNIRS) calibrations, developed by Curtin University of Technology and ChemCentre WA, were used to predict the nutritional attributes of sheep diets.Sheep production was found to be affected by rainfall, seasons, management and differing blood lines. In 2006, live weights, BCS and wool fibre diameter increased in response to high summer rainfall. Lower rainfall in 2007 resulted in variable, but generally less animal production with lower live weights, BCS and wool fibre diameter. Management decisions to avoid mating in 2006 on CGS; and agistment for sheep on RGS at the end of 2006 resulted in better sheep production results. Sheep originally sourced from Station 2 generally had higher live weights than sheep sourced from Station 1, suggesting a difference in bloodlines.Faecal DNA provided useful information regarding diet selection and diversity of sheep grazing on the Arid Shrublands of WA. Of the species that were DNA profiled, the sheep ate Acacia saligna, Aristida contorta, Atriplex spp., Enchylaena tomentosa, Frankenia sp., Ptilotus obovatus, Rhagodia eremaea and Scaevola spinescens in 2006 whilst in 2007; the sheep consumed A. saligna, A. contorta, Atriplex spp., Eremophila forrestii, Enneapogon caerulescens, Frankenia spp., Maireana spp., Ptilotus obovatus, Rhagodia eremaea, Solanum lasiophyllum and Stipa elegantissima. However, there were 28 amplified bands in 2006 and 51 in 2007 that did not conclusively match any of the reference plant species. This indicates that the sheep were consuming diets that contained more species than what was analysed in this study. Faecal DNA results indicated a decrease in the diversity of the diets selected by the sheep during summer, which coincided with a decrease in animal production.Native plants were found to be low in OMD and ME, but high in crude protein (CP), and variable in mineral content. Sheep were able to select diets adequate in OMD, ME and CP for maintenance requirements, and low in tannins and phenolics, although continuous drought conditions resulted in reduced production, indicating that the sheep were not getting adequate nutrition to meet their growth requirements. The use of fNIRS provided more useful information about the quality of the diet of the sheep than nutritionally profiling individual plants. NDVI was found to be related to dietary OMD and wool fibre diameter changes along the staple.Overall, the effects of management seemed to be secondary to the effects of climate on sheep production and nutrition. The statistical accuracy of results was low; however, the use of advanced technologies to explore relationships between climate, plant nutritional profiles and animal production and nutrition has provided an expansion of knowledge of sheep nutrition in the region. This extra knowledge may help land owners in the region to make more sustainable management decisions concerning livestock management and grazing pressures on native pastures.

Resumo:
The field buses, and particularly the ‘PROFIBUS’, are currently widely used in automation systems, with the intention to automate industrial applications. It is of the utmost importance that one should understand how these systems operate, because failure to understand may result in improper applications, which can ultimately lead to intense network problems and, consequently, lead to potential catastrophic failures in industrial equipment, as well as compromising the health and safety of the people. This research was the performance evaluation of SAMANCOR PROFIBUS network that controls the chrome manufacturing plant. The problem with the network was that it was failing intermittently. These network failures resulted in loss of production, loss of throughput, compromised quality, downtime due to reworks, high costs in energy used to rework, and equipment damage or failure. One of the OBJECTIVES of the research was to carry out a performance evaluation of the PROFIBUS network in terms of the possible electromagnetic interference (EMI) within the plant’s PLC network. This topic emanated from the network service providers that kept insisting that the network was unstable, due to possible electromagnetic interference caused by possible high voltage cables running next to the plant network cables. This assumption was without fact, and hence the research was conducted. The QUANTITATIVE research method was used to conduct the research, where simulation of the plant network, using external parameters, were used to carry out the research. Furthermore, experiments were conducted and the physical measurements were performed on the network, where parameters derived from these measurements were used to compare the two networks. In essence, the network was tested under known configurations. The manner in which the network was simulated was that of stepping up the electrical current from the external device, and recording the response of the network. A stand-alone network rig was built and used to carry out the tests, and the results were compared with those obtained from the plant network.

The organizational and digital transformation projects are very complex because of many reasons, and they depend on the initial project's phase, which depends on the critical building blocks (BB)-based unbundling process (UP). The organizational UP (OUP), which is a set of UPs whose primary goal is to disassemble the organization's legacy structure, system administration, resources, applications, working models, and components into dynamic reusable BBs which can be (re)used in standardized architectural BBs. The UP faces major difficulties because of the organization's heterogenous human profiles/cultures, system parts, managers' financial ambitions, and the project's limited time/budgets. Another major problem is that transformation and innovation techniques have been monopolized for achieving only immediate tangible goals like business and financial aspects/profits and where the intangible complex technical aspects are simply ignored.

Resumo:
In order to improve efficiency of high-performance drilling processes while preserving tool life, the current study focuses on the design and implementation of an optimal fuzzy-control system for drilling force. The main topic of this study is the design and implementation of a networked fuzzy controller. The control algorithm is connected to the process through a multipoint interface (MPI) bus, a proprietary programming and communication interface for peer-to-peer networking that resembles the PROFIBUS protocol. The output (i.e., feed-rate) signal is transmitted through the MPI; therefore, network-induced delay is unavoidable. The optimal tuning of the fuzzy controller using a maximum known delay is based on the integral time absolute error (ITAE) criterion. In this study, a step in the force reference signal is considered a disturbance, and the goal is to assess how well the system follows set-point changes using the ITAE criterion. The main advantage of the approach presented herein is the design of an optimal fuzzy controller using a known maximum allowable delay to deal with uncertainties and nonlinearities in the drilling process and delays in the network-based application. In order to suppress the cutting-force increase, the feed rate is decreased gradually as the drilling depth increases, and the cutting force is quite well regulated at the given setpoint. The good transient response is verified by improvements in the integral time absolute error (11.77), integral time square error (2.912) and integral of absolute error (12.81) performance indices. Moreover, the experimental results without oscillations and overshoot corroborate that increases and fluctuations in force drilling can be suppressed despite an increase in drilling depth. Thus, the drilling process can be stabilized and the risk of drill failure can be greatly reduced through a fuzzy-control system.

Exploring mechanisms involved in grape bud dormancy: Large-scale analysis of expression reprogramming following controlled dormancy induction and dormancy release. United States Department of Agriculture, dezembro de 2002. http://dx.doi.org/10.32747/2002.7587232.bard.

Resumo:
The timing of dormancy induction and release is very important to the economic production of table grape. Advances in manipulation of dormancy induction and dormancy release are dependent on the establishment of a comprehensive understanding of biological mechanisms involved in bud dormancy. To gain insight into these mechanisms we initiated the research that had two main objectives: A. Analyzing the expression profiles of large subsets of genes, following controlled dormancy induction and dormancy release, and assessing the role of known metabolic pathways, known regulatory genes and novel sequences involved in these processes B. Comparing expression profiles following the perception of various artificial as well as natural signals known to induce dormancy release, and searching for gene showing similar expression patterns, as candidates for further study of pathways having potential to play a central role in dormancy release. We first created targeted EST collections from V. vinifera and V. riparia mature buds. Clones were randomly selected from cDNA libraries prepared following controlled dormancy release and controlled dormancy induction and from respective controls. The entire collection (7920 vinifera and 1194 riparia clones) was sequenced and subjected to bioinformatics analysis, including clustering, annotations and GO classifications. PCR products from the entire collection were used for printing of cDNA microarrays. Bud tissue in general, and the dormant bud in particular, are under-represented within the grape EST database. Accordingly, 59% of the our vinifera EST collection, composed of 5516 unigenes, are not included within the current Vitis TIGR collection and about 22% of these transcripts bear no resemblance to any known plant transcript, corroborating the current need for our targeted EST collection and the bud specific cDNA array. Analysis of the V. riparia sequences yielded 814 unigenes, of which 140 are unique (keilin et al., manuscript, Appendix B). Results from computational expression profiling of the vinifera collection suggest that oxidative stress, calcium signaling, intracellular vesicle trafficking and anaerobic mode of carbohydrate metabolism play a role in the regulation and execution of grape-bud dormancy release. A comprehensive analysis confirmed the induction of transcription from several calcium–signaling related genes following HC treatment, and detected an inhibiting effect of calcium channel blocker and calcium chelator on HC-induced and chilling-induced bud break. It also detected the existence of HC-induced and calcium dependent protein phosphorylation activity. These data suggest, for the first time, that calcium signaling is involved in the mechanism of dormancy release (Pang et al., in preparation). We compared the effects of heat shock (HS) to those detected in buds following HC application and found that HS lead to earlier and higher bud break. We also demonstrated similar temporary reduction in catalase expression and temporary induction of ascorbate peroxidase, glutathione reductase, thioredoxin and glutathione S transferase expression following both treatments. These findings further support the assumption that temporary oxidative stress is part of the mechanism leading to bud break. The temporary induction of sucrose syntase, pyruvate decarboxylase and alcohol dehydrogenase indicate that temporary respiratory stress is developed and suggest that mitochondrial function may be of central importance for that mechanism. These finding, suggesting triggering of identical mechanisms by HS and HC, justified the comparison of expression profiles of HC and HS treated buds, as a tool for the identification of pathways with a central role in dormancy release (Halaly et al., in preparation). RNA samples from buds treated with HS, HC and water were hybridized with the cDNA arrays in an interconnected loop design. Differentially expressed genes from the were selected using R-language package from Bioconductor project called LIMMA and clones showing a significant change following both HS and HC treatments, compared to control, were selected for further analysis. A total of 1541 clones show significant induction, of which 37% have no hit or unknown function and the rest represent 661 genes with identified function. Similarly, out of 1452 clones showing significant reduction, only 53% of the clones have identified function and they represent 573 genes. The 661 induced genes are involved in 445 different molecular functions. About 90% of those functions were classified to 20 categories based on careful survey of the literature. Among other things, it appears that carbohydrate metabolism and mitochondrial function may be of central importance in the mechanism of dormancy release and studies in this direction are ongoing. Analysis of the reduced function is ongoing (Appendix A). A second set of hybridizations was carried out with RNA samples from buds exposed to short photoperiod, leading to induction of bud dormancy, and long photoperiod treatment, as control. Analysis indicated that 42 genes were significant difference between LD and SD and 11 of these were unique.

Resumo:
In the global economic model, the service sector continues to gain ground on the manufacturing sector and trends such as the integration of new technologies into production processes are advancing inexorably. Advanced economies are pushed to specialise, supported by their regional innovation systems, and cities are emerging as key and strategic centres of activity. In this context, Knowledge Intensive Business Services (KIBS) are presented as critical due to their capacity to promote innovation within the regional productive fabric and smart specialisation strategies, the promotion of advanced manufacturing, the generation of quality employment and the stimulation of economic growth, especially in urban environments. This is why many cities, prioritizing KIBS to stimulate their economy, need to create and retain talent for this sort of industry. Likewise, vocational and education training (VET) systems, such as the Basque VET system, have so far developed their greatest strengths in the field of manufacturing knowledge. Due to this, VET seems to be obliged to adapt to this new scenario, in which KIBS and cities stand out, in order to continue to maintain their level of excellence. KIBS have been extensively examined, but until now no one had posed the following questions: What is the role of vocational training in KIBS? To what extent are VET profiles (and will VET profiles be) relevant in KIBS? This study will show an emerging trend in the labour market. This is the growing relevance of technology profiles with VET background in KIBS, especially in technology-based KIBS. VET technology profiles can be consolidated as one of the main implementing agents of the digital transformation (cybersecurity, blockchain, cloud computing, UX design, artificial intelligence, scientific computing...). To this end, hybridisation with other fields of knowledge but also with studies of other kinds such as university studies may be essential.

Vélez-Velásquez, Juan Sebastián. Banning Price Discrimination under Imperfect Competition: Evidence from Colombia's Broadband. Banco de la República de Colombia, dezembro de 2020. http://dx.doi.org/10.32468/be.1148.

Texto completo da fonte
Resumo:
Economic theory is inconclusive regarding the effects of banning third-degree price discrimination under imperfect competition because they depend on how the competing firms rank their market segments. When, relative to uniform pricing, all competitors want higher prices in the same market segments, a ban on price discrimination will reduce profits and benefit some consumers at the expense of others. If, instead, some firms want to charge higher prices in segments where their competitors want to charge lower prices, price discrimination increases competition driving all prices down. In this case, forcing the firms to charge uniform prices can increase their profits and reduce consumer surplus. We use data on Colombian broadband subscriptions to estimate the demand for internet services. Estimated preferences and assumptions about competition are used to simulate a scenario in which firms lose their ability to price discriminate. Our results show large effects on consumer surplus and large effects on firms’ profits. Aggregate profits increase but the effects for individual firms are heterogeneous. The effects on consumer welfare vary by city. In most cities, a uniform price regime causes large welfare transfers from low-income households towards high-income households and in a few cities, prices in all segments rise. Poorer households respond to the increase in prices by subscribing to internet plans with slower download speed.

The political right-wing populism topography in Norway has for decades been dominated by the Norwegian Progress Party, which is characterized by a combination of social-conservative values like nativism combined with market liberalism. However, following the invasion of Ukraine, it is not issues of security and sovereignty that take centre stage in the Progress Party’s discourse but high energy prices. As a fossil fuel producer, Norway profits from the ensuing energy crisis and Europe’s search for other energy providers than Russia. These profits, the Progress Party argues, are unduly awarded to the state treasury while “ordinary people” and entrepreneurs struggle. Populism thus appears in Norway as a way for a right-wing opposition party to challenge the centre-left government.

Paleozoic platform carbonate rocks of the Rocky Mountains host Mississippi Valley-type (MVT), magnesite, barite, and REE-barite-fluorite deposits. Farther west, platform carbonate rocks of the Kootenay Arc host MVT and fracture-controlled replacement (FCR) deposits. This is the first systematic LA-ICP-MS study of carbonates in MVT and FCR deposits. We investigated seven MVT deposits in the Rocky Mountains, and five MVT deposits in the Kootenay Arc. None of the post-Archean Australian shale (PAAS)-normalized REE profiles show light REE (LREE) depletion and strong negative Ce anomalies characteristic of modern seawater: some profiles are nearly flat; others show depletion in LREE similar to seawater but without negative Ce anomalies; others are middle REE enriched. Carbonates with a strong positive Eu anomaly precipitated from or interacted with different fluids than carbonates with flatter profiles without a strong positive Eu anomaly. REE signatures reflect crystallization conditions of primary carbonates, and crystallization and re-equilibration conditions of carbonates with ambient fluids during diagenesis, deep burial, and/or metamorphic recrystallization. Chemical evolution of fluids along their migration path, fluid-to-rock ratio, fluid acidity, redox, and temperature also influence REE profile shape, which helps establish genetic and timing constraints on studied deposits and improves knowledge of the metallogeny of the Kootenay Arc and Rocky Mountains.

Resumo:
Pear-feeding psyllids in the genus Cacopsylla (Hemiptera: Psyllidae) are among the most important arthropod pests of pears worldwide. These pests are exceedingly difficult to control, and new management tools are needed. Sex attractantpheromones have been used in IPM programs for pests of pome fruits (especially Lepidoptera), but not as yet for pest Hemiptera. Results of the current project showed that males of two psyllid pests of pears, Cacopsylla bidens (Israel) and Cacopsylla pyricola (North America), use volatile or semi-volatile compounds to locate female psyllids for mating. For both species, the attractants can be collected from the cuticle of females by washing live female psyllids with an appropriate solvent. Analysis of these washes by gas chromatography – mass spectrometry led to the following discoveries: Psyllid cuticles contain a mix of hydrocarbons, straight chain and branched alkanes, and long chain aldehydes The two species have different chemical profiles Chemical profiles change seasonally and with reproductive status Chemical profiles differ between male and reproductive female psyllids Several specific compounds found to be more abundant in attractive females than males were identified and synthesized. Behavioral assays (olfactometer) were then used to determine whether these compounds were attractive to males. Two compounds showed promise as attractants for male psyllids: 7-methylheptacosane (C. bidens) and 13-methylheptacosane (C. pyricola and C. bidens). These are the first sex attractantpheromones identified for any psyllid species. Field tests showed that the chemicals could be used to attract males under orchard conditions, but that effectiveness in the field appeared to be seasonally variable. Future research plans include: (a) test mixtures of compounds; (b) explore seasonality in field response to compounds; (c) determine whether chirality of the two compounds affects their attractiveness; and (d) compare different types of traps and release devices to optimize lure performance.

Les défis actuels des écosystèmes en IA sont caractérisés par une forte demande de talents en intelligence numérique, une demande de formations qui répondent aux besoins du marché, l’émergence de nouveaux profils d’emploi, une demande en hausse pour le rehaussement des compétences des travailleurs en emploi et une adoption de l’IA par les entreprises encore limitée à certains secteurs. C’est ce qui a motivé la mise en place de nombreuses initiatives des établissements d’enseignements et d’autres types d’acteurs, autant en matière de formation que de transfert de connaissances. Pour le Québec, les rapports qui ont été publiés en 2020 et 2021 ainsi que les entrevues menées auprès des acteurs de l’écosystème en IA ont permis de faire un survol des forces et des faiblesses. Le Québec est reconnu pour son importante communauté de recherche en IA et son positionnement pour un développement responsable de l’IA. De nombreux établissements d’enseignement ont remodelé leurs programmes pour répondre aux enjeux du numérique et aux besoins du marché. Des initiatives concertées cégeps-universités ont été mises en place et des collaborations de recherche appliquée ou l’intégration de stages ont vu le jour. Plusieurs instituts et organisations participent à accompagner les entreprises dans l’adoption de l’IA. Toutefois, la multiplicité des acteurs est souvent vue comme un obstacle pour les entreprises. Plusieurs organisations n’utilisent pas l’IA faute de compréhension générale de l’IA et de ses applications et en raison de la difficulté d’évaluer leur niveau de maturité, d’identifier les compétences nécessaires ou les besoins de formation pour les employés. Dans le cadre de cette étude, six grands constats ont pu être faits concernant les pratiques innovantes en matière de formation et de transfert de connaissances existantes à partir de l’analyse de plusieurs écosystèmes en IA dans plusieurs régions du monde. À la suite de ces constats et des discussions que nous avons eues avec des représentants de l’écosystème québécois, nous avons identifié certaines pistes qui pourraient être recommandées pour le Québec.
