Texte intégralRésumé :
The concept of commercialization is a strategic step in introducing Kapiten coffee products to be the flagship of Pasuruan Regency and brands with measurable coffee quality. This commercialization involves three important actors; government, academics and entrepreneurs (triple helix) so that the captain's coffee succeeded in bringing Pasuruan Regency. This study uses a non-metric Multidimensional Scaling method with ranking data processing. The method used is that data is obtained through preference ranking, where the steps are as follows: making a questionnaire, ranking various brands based on existing attributes, then mapping the attributes. Data on this research take from some of coffe brand in East Java Province using case study. In addition, this study also uses the Critical Path Method which is used to measure the duration of the work. This method will greatly help project managers in analyzing, planning and scheduling projects more efficiently. The results of this study indicate that Kapiten coffee is superior in terms of taste, soft texture to attractive packaging, which is an important strategy to introduce Kapiten coffee products into the free market; both domestically and internationally. As for the captain's coffee, it takes 51 days to be widely marketed. Kapiten coffee has advantages and tastes, textures and packaging that are distinctive from other coffees. So this is a special attraction for consumers.

Texte intégralRésumé :
Not all customers can be served by the company. Each company needs to identify marketsegments that can be served effectively by differentiating the main market segments, aiming at one ortwo segments and developing products so that there are always new breakthroughs. A company in orderto excel in competition must be able to recognize its market segment, target and product position againstits competitors. This research aims to determine the segmenting, targeting, and positioning of MangsiCoffee powder. The sampling technique used is the nonprobability sampling method that is accidentialsampling. Segmenting and targeting is done by using crosstab analysis, while positioning uses multidimensional scaling analysis and correspondence analysis. Mangsi Coffee powder market segmentationbased on the characteristics of consumers are men who are adults, graduated from tertiary education (last education), work as employees with monthly expenditure above the Denpasar City UMK in 2019(Rp. 2,553,000.00). Mangsi Coffee consumers based on psychographic segmentation tend to choosequality products and make coffee consumption habits a trend and lifestyle while Mangsi Coffeeconsumers based on segmentation of consumer behavior tend to choose products according to theirbenefits. Positioning using multi-dimensional scaling analysis (MDS) shows that, Mangsi Coffeepowder is not in one quadrant with all three competing products. The map shows that all four productsare in different quadrants. CA analysis (correspondence analysis), shows the superiority of MangsiCoffee powder products when compared with competitors' products is an attribute in terms ofpackaging. The importance of companies to pay attention to segmenting, targeting, and positioning tobe able to focus on achieving company goals and survive in fierce market competition.

Texte intégralRésumé :
Coffee production in Côte d'Ivoire has been declining sharply for more than twenty years due to degradation in soil fertility status. The objective of this study was to map the mineral requirements of coffee trees in different production regions and to recommend immediate and long-term intervention strategies for soil management. In this study, the diagnosis of the chemical needs of 156 soil samples from major coffee production areas was used. We used a soil diagnostic model specific to coffee fertilization combined with geographic information systems (GIS). The combination of fertilizer formulas from the coffee soil diagnostic model, recent climatic data and soil units of the coffee growing areas allowed the elaboration of a thematic map showing a total of five basic formulas (N-P2O5-K2O-CaO-MgO) adapted to the real nutritional needs of coffee trees according to their agropedoclimatic environments. Two of these formulas cover 90% of the area studied. This study will enable appropriate soil management for the sustainable productivity of coffee trees in Côte d'Ivoire.

Texte intégralRésumé :
Three in one instant coffee is popular among university students. A variety brands of such instant coffee are available on the market. However, the literature on the sensory aspects of the instant coffee is rather limited slim. The project aimed to test three-in-one instant coffee sachets for their sensory characteristics. Two methods, CATA (Attributes and Emotional Mapping) and Flash Profile (extension of Free Choice Profiling) were employed to generate the attribute profiles and emotional dashboard. Sixty IPB University students were selected as panelists. Sensory attributes terminologies and their relation to emotion were generated using Focus Group Discussion among instant coffee heavy drinker. Profile of coffee D showed a creamy texture, while sweetness and milky was dominant when it came to coffee B and coffee C. The creaminess in coffee G was strongly related to feelings of happiness in a consumer. In addition, the sweet and milky taste and flavor in coffee B was seen as a relaxing and luxurious feeling. A Preference Mapping was constructed, and it showed that sweetness, milky, and creaminess improved the liking of the student consumers that make coffee C the most preferred brand among the panelists. In short, the use of flash profiles and check-all-it-dilute/CATA (attributes and emotional) equipped with preference mapping can provide emotional attributes and dashboards that will be important to understand products more than just consumer liking.

Texte intégralRésumé :
The coffee sector is working towards sector-wide commitments for sustainable production. Yet, knowledge of where coffee is cultivated and its environmental impact remains limited, in part due to the challenges of mapping coffee using satellite remote sensing. We recognize the urgency to capitalize on recent technological advances to improve remote sensing methods and generate more accurate, reliable, and scalable approaches to coffee mapping. In this study, we provide a systematic review of satellite-based approaches to mapping coffee extent, which produced 43 articles in the peer-reviewed and gray literature. We outline key considerations for employing effective approaches, focused on the need to balance data affordability and quality, classification complexity and accuracy, and generalizability and site-specificity. We discuss research opportunities for improved approaches by leveraging the recent expansion of diverse satellite sensors and constellations, optical/Synthetic Aperture Radar data fusion approaches, and advances in cloud computing and deep learning algorithms. We highlight the need for differentiating between production systems and the need for research in important coffee-growing geographies. By reviewing the range of techniques successfully used to map coffee extent, we provide technical recommendations and future directions to enable accurate and scalable coffee maps.

Texte intégralRésumé :
The genus Coffea L. has around 100 native species distributed in tropical and subtropical areas in Africa, and the most important economic species are C. arabica and C. canephora. C. arabica is exceptional in the genus since it is the only species so far analyzed which is self-compatible, and a natural polyploid with 2n=4x=44 chromosomes; it is considered to be a segmental allopolyploid because it presents a disomic inheritance and a regular meiotic behavior. All other species in the genus are self-incompatible diploids with 2n=2x=22. Cytogenetic studies in Coffea, undertaken since 1912, have followed various phases: initial studies were limited only to establishing chromosome counts. Subsequent studies characterized the karyotypes of various species using conventional cytological techniques. As the somatic metaphase chromosomes of coffee are very small (1 - 3 µm) and morphologically symmetrical, these studies resulted in uniform karyotypes that show almost no differences among species. Since genetic improvement of coffee trees has progressed mainly by means of interspecific hybridizations involving wild species, analyses of microsporogenesis in species and hybrids were needed to establish their genetic affinity and relationships. The first successful attempts to differentiate coffee chromosomes longitudinally were made by mapping pachytene chromomeric patterns and by C and NOR banding techniques. From 1998 onwards, the use of banding techniques with the fluorochromes DAPI and CMA3, and also the cytomolecular technique FISH using rDNA probes, has increased the longitudinal differentiation of coffee chromosomes. The use of the GISH technique with total genomic DNA has revealed the parental species that originated C. arabica species.

Texte intégralRésumé :
The coffee chain business has penetrated the country since many years ago until unconsciously it has become the lifestyle of many people, especially students and business people of various ages. Not only that, branded coffee chains that entered Indonesia have become a symbol of pride and compete with local coffee businesses. To become a branded coffee chain that dominates the market, of course, it requires customers who can continue to choose the coffee chain. Companies must know find out how customers perceive their company in various ways as a benchmark for strategies that they will continue to use in the future.. The objectives of this study are To Know the Perceptual Mapping of Branded Coffee Chains in Manado (Starbucks and the Coffee Bean). The analytical method used is Multi-dimensional Scaling Analysis with 7p’s as indicators. Based on the results of the analysis and discussion using Perceptual Mapping and Multi-dimensional Scaling (MDS) test, it is concluded that the results of hypothesis testing found that Starbucks becomes the most preferred brand of Coffee Chains compared to the Coffee Bean in Manado.

Texte intégralRésumé :
Coffee production was closely linked to the economic development of Brazil and, even today, coffee is an important product of the national agriculture. The State of Minas Gerais currently accounts for 52% of the whole coffee area in Brazil. Remote sensing data can provide information for monitoring and mapping of coffee crops, faster and cheaper than conventional methods. In this context, the objective of this study was to assess the effectiveness of coffee crop mapping in Monte Santo de Minas municipality, Minas Gerais State, Brazil, from fraction images derived from MODIS data, in both dry and rainy seasons. The Spectral Linear Mixing Model was used to derive fraction images of soil, coffee, and water/shade. These fraction images served as input data for the supervised automatic classification using the SVM - Support Vector Machine approach. The best results concerning Overall Accuracy and Kappa Index were obtained in the classification of the dry season, with 67% and 0.41, respectively.

Texte intégralRésumé :
Although from a food safety point, coffee is considered a shelf-stable product, changes in volatiles over time due to out-gassing and chemical reactions lead to perceivable differences in coffee aroma and “freshness”. Previous studies have looked at the impact of storage conditions on ground or brewed coffee. This study seeks to answer the question of how coffee consumers perceive the smell of coffee grounds of whole beans that have been stored under different conditions: freezer vs. room temperature for 9 weeks compared to a newly roasted control (stored for 1 day). Green beans from the same production lot were roasted to two different levels to also evaluate the impact of roast level on aroma changes. Using projective mapping (PM) followed by ultra-flash profiling (UFP), 48 coffee consumers evaluated, using only smell, 6 different freshly ground coffee samples presented in blind duplicates. In parallel, the profiles of 48 previously reported important coffee volatiles were measured by headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) to relate chemical changes to perceivable sensory aroma changes. Overall, consumer product maps mimicked the instrumental measurements in that the lighter roast coffees showed smaller changes due to storage conditions compared to the dark roast samples. Consumers also perceived the frozen dark roast samples to be more similar to the newly roasted control than the samples stored at room temperature.

Texte intégralRésumé :
Currently, the system that developing countries use to map coffee crops is expensive, tedious and inaccurate; therefore coffee maps cannot be updated frequently and production cannot be accurately estimated. If such countries could map coffee crops in a cost-effective way, they would have an advantage in terms of setting the prices and getting a higher return for their product. Here I hypothesize that coffee systems can be properly characterized and mapped using the spectral and spatial information derived from satellite images and topographic data. I also believe that during the spatial analysis of the data, the additional information provided by an object-based approach (comprehensive information about the shape and context of a particular area) provides more information than a pixel-based one, traditionally used in the integration of Remote Sensing and Geographic Information Systems (GIS). I statistically analyzed spatial and spectral characteristics of different coffee systems (monoculture, polyculture and agroforestry systems) in three study areas in Colombia of 70km2 each. I integrated satellite images and topographic grids using both pixel-based and object-based approaches in a hierarchical approach and the results were compared. Following this hierarchical approach, a preliminary classification was performed to reduce the number of classes spectrally similar to coffee systems. Then in a second step, the classification was refined using decision rules from the statistical analysis of objects (composed of at least 3 pixels). Finally, using the same objects, the classification was refined further, through linear spectral unmixing. The results show that the rule-based classification combined with an object-based approach can improve the overall accuracy of the classification by 3% and by 17.47% for the coffee class when compared to the pixel-based analysis. The linear spectral unmixing, however, does not contribute to improve the classification aActuellement, le système que les pays en voie de développement emploient pour cartographier les récoltes de café est cher, pénible et imprécis. Ainsi, les cartes de café ne peuvent être mises à jour fréquemment et la production ne peut pas être estimée avec exactitude. Si ces pays pouvaient cartographier les récoltes de café d'une manière plus économique, ils auraient un avantage pour fixer les prix et obtenir des revenus plus élevés pour leur produit. Je pose ici l'hypothèse que les zones de café peuvent être correctement caractérisés et cartographiés en utilisant l'information spectrale et spatiale dérivée des images satellites et des données topographiques. Je suppose également que pendant l'analyse spatiale des données, l'information additionnelle fournie par une approche 'object-basée' (informations complètes sur la forme et le contexte d'une zone particulière) fournit plus d'informations que qu'une approche 'pixel-basée', traditionnellement utilisée dans l'intégration de la télédétection et des systèmes d'information géographiques (GIS). J'ai analysé (statistiquement) les caractéristiques spatiales et spectrales des systèmes de café dans trois secteurs d'étude en Colombie de 70km2 chacun. J'ai intégré des images satellites et des grilles topographiques en utilisant les 2 approches 'pixel-basée' et 'object-basée' dans une approche hiérarchique et les résultats ont été comparés. Des objets ont été formés sur la base de la similitude spectrale des bandes 2.3.4 5 et 7. Après l'approche hiérarchique, une classification préliminaire a été effectuée pour réduire le nombre de classes spectralement semblables aux systèmes de café. Alors, dans une deuxième étape, la classification est affinée en utilisant des règles de décision sur l'analyse statistique de plus petits objets (composés de 5 pixel ou moins). Finalement, en utilisant les mêmes objets, la classification a été de nouveau affin

Resumo: A produção de café esteve intimamente ligada ao desenvolvimento econômico do Brasil e ainda hoje o café é um importante produto da agricultura nacional. O Estado de Minas Gerais responde atualmente por 52% de toda a área de café do Brasil. Dessa forma, dada a importância da cafeicultura para a economia brasileira, é necessário desenvolver e melhorar as metodologias para seu monitoramento. Dados de sensoriamento remoto podem fornecer informações para o monitoramento e o mapeamento de café de maneira mais rápida e menos onerosa do que os métodos convencionais. Nesse contexto, os objetivos desta pesquisa foram identificar a bienalidade da cultura de café por meio de dados do sensor MODIS, juntamente com dados de estações meteorológicas, entre os anos de 2004 a 2012, e avaliar a eficácia das imagens-fração derivadas do sensor MODIS no mapeamento automático das áreas de café do município de Monte Santo de Minas/MG. Foi utilizada uma série temporal com 163 imagens da banda NIR do MODIS, produto MOD13Q1, para se extrair os valores de refletância dos pixels com pelo menos 80% de café. Dados diários de temperatura e precipitação foram agrupados de acordo com a resolução temporal das imagens (16 dias) para o cálculo do balanço hídrico. Para o mapeamento das áreas de café, foram utilizadas imagens do MODIS, bandas MIR, NIR e RED, dos períodos seco e chuvoso. Através do Modelo Linear de Mistura Espectral foram derivadas imagens-fração de solo, café e água/sombra. Estas imagens-fração serviram como dados de entrada para a classificação automática supervisionada com o método SVM - Support Vector Machine. Os resultados mostraram que para o monitoramento do café os dados de refletância dos períodos de colheita apresentaram maior correlação com a alternância da quantidade da produção. A partir da matriz de erro montada entre as classificações e as máscaras de referência, observou-se que os melhores resultados de Exatidão Global e Índice Kappa foram obtidos na classificação do período seco, sendo 67% e 0,41, respectivamente. Análises estatísticas de correlação e coeficiente de variação aplicadas sobre as imagens-fração de café permitiram melhor compreensão da complexidade do mapeamento do café
Abstract: Coffee production was closely linked to the economic development of Brazil and even today coffee is an important product of national agriculture. The State of Minas Gerais currently accounts for 52% of the whole area of coffee in Brazil. Thus, given the importance of the coffee crops to Brazilian economy, it is necessary to develop and improve methodologies for its monitoring. Then, remote sensing data can provide information for monitoring and mapping of coffee crops faster and cheaper than conventional methods. In this context, the objectives of this study were to identify the biennial yield of the coffee crop using data from MODIS and meteorological stations, over the period between 2004 and 2012, and assess the effectiveness of the fraction-images derived from MODIS in the automatic mapping of the areas of coffee in Monte Santo de Minas/MG. Were used a time series of 163 images of NIR band from MODIS, MOD13Q1 product, to extract the values of reflectance of pixels with at least 80% of coffee. Daily data of air temperature and precipitation were compiled to 16-day intervals to match the temporal resolution of MODIS imagery and to calculate the water balance. For coffee mapping, we used MODIS imagery, MIR, NIR and RED bands, of dry and rainy seasons. Through the Spectral Linear Mixing Model were derived fraction images of soil, coffee and water/shadow. These fraction images served as input data for supervised classification with SVM - Support Vector Machine approach. The results showed that for coffee monitoring the reflectance data of harvest period presented higher correlation with the alternation of coffee production. From the error matrix between the classifications and reference masks, it was observed that the best results of Overall Accuracy and Kappa Index were obtained in the classification of the dry season, with 67% and 0.41, respectively. Statistical analyses of correlation and coefficient of variation applied over images fraction of coffee allowed a better understanding about the complexity of mapping coffee

Os nematoides são importantes fitoparasitas que se constituem em um problema sério para o cultivo do café no Brasil. Como a ocorrência de nematoides no sistema radicular do cafeeiro causa desequilíbrios nutricionais na planta que provocam variações na resposta espectral da folha e define uma configuração espacial característica às áreas infectadas, o objetivo desta pesquisa avaliar o potencial de dados de sensoriamento remoto adquiridos em multiescala para discriminar e mapear o café sadio, em estágio inicial de infecção e severamente infectado. A pesquisa foi desenvolvida em três áreas experimentais, localizadas no sul do estado de Minas Gerais, nas quais foi certificada a ocorrência de nematoides e realizadas medições de variáveis biofísicas e dados hiperespectrais na folha e sobre o dossel da planta. Os dados hiperespectrais também foram utilizados em simulação de bandas dos sensores do RapidEye e OLI/Landsat 8 para identificar as faixas espectrais mais sensíveis para a discriminação de patógenos em plantas de café. Nenhum dos parâmetros biofísicos avaliados discriminou eficientemente as folhas de plantas sadias e infectadas, mas a simulação de bandas indicou que os intervalos espectrais do vermelho, vermelho limítrofe e infravermelho próximos do RapidEye foram complementares para a discriminação de plantas de café sadio e dos dois níveis de infecção. Essas bandas, mais uma imagem NDVI, foram utilizadas na classificação das áreas infectadas por nematoides, a qual definiu a distribuição espacial de café sadio e dos dois níveis de infecção, com uma acurácia global de 78% e coeficiente kappa de 0,71. A classificação não supervisionada da imagem multiespectral OLI/Landsat 8 também definiu as três condições, porém com baixa confiabilidade (coeficiente kappa igual a 0,41). Por outro lado, uma inferência espacial quantitativa da concentração de nematoides/cm³ no solo, a partir de um modelo empírico baseado na imagem RapidEye, apresentou um erro consideravelmente alto (21,89%).
Nematodes are important phytoparasites that constitute a serious issue for coffee cultivation in Brazil. Because root infection by nematodes induces spectral variation in leaves and defines a unique spatial configuration in the cultivation field, the aim of this study is to evaluate the potential of remote sensing data acquired in multiscale to discriminate and map healthy, early infected and severely infected coffee plants. This study was carried out in three experimental areas, located in the in southern Minas Gerais State, in which the occurrence of nematodes was certified and biophysical and hyperspectral measurements of the leaves and on the canopy were made. Hyperspectral data were also used to simulate the bands of the RapidEye and OLI/Landsat 8 sensors to identify the most sensitive spectral ranges for pathogen discrimination in coffee plants. None of the biophysical parameters efficiently discriminated the leaves of healthy and infected plants, but the band simulations indicated that red, red edge and near infrared spectral ranges were complementary to the discrimination of healthy coffee plants and the two levels of infection. These bands, plus an (NDVI) image, were used for a multispectral classification of healthy and nematode-infected areas. The multispectral classification defined the spatial distribution of healthy, early infected and two levels of infection, with an overall accuracy of 78% and kappa coefficient of 0.71. The unsupervised classification of the multispectral image OLI/Landsat 8 also defined the three conditions, but with low reliability (kappa coefficient equal to 0.41). In contrast, a quantitative spatial inference of the soil nematode concentration/cm³, from an empirical model based on the RapidEye image, presented a considerably high error (21.89%).

Texte intégralRésumé :
Les habitudes de consommation de substances psychoactives, le stress, l’obésité et les traits cardiovasculaires associés seraient en partie reliés aux mêmes facteurs génétiques. Afin d’explorer cette hypothèse, nous avons effectué, chez 119 familles multi-générationnelles québécoises de la région du Saguenay-Lac-St-Jean, des études d’association et de liaison pangénomiques pour les composantes génétiques : de la consommation usuelle d’alcool, de tabac et de café, de la réponse au stress physique et psychologique, des traits anthropométriques reliés à l’obésité, ainsi que des mesures du rythme cardiaque (RC) et de la pression artérielle (PA). 58000 SNPs et 437 marqueurs microsatellites ont été utilisés et l’annotation fonctionnelle des gènes candidats identifiés a ensuite été réalisée.
Nous avons détecté des corrélations phénotypiques significatives entre les substances psychoactives, le stress, l’obésité et les traits hémodynamiques. Par exemple, les consommateurs d’alcool et de tabac ont montré un RC significativement diminué en réponse au stress psychologique. De plus, les consommateurs de tabac avaient des PA plus basses que les non-consommateurs. Aussi, les hypertendus présentaient des RC et PA systoliques accrus en réponse au stress psychologique et un indice de masse corporelle (IMC) élevé, comparativement aux normotendus. D’autre part, l’utilisation de tabac augmenterait les taux corporels d’épinéphrine, et des niveaux élevés d’épinéphrine ont été associés à des IMC diminués. Ainsi, en accord avec les corrélations inter-phénotypiques, nous avons identifié plusieurs gènes associés/liés à la consommation de substances psychoactives, à la réponse au stress physique et psychologique, aux traits reliés à l’obésité et aux traits hémodynamiques incluant CAMK4, CNTN4, DLG2, DAG1, FHIT, GRID2, ITPR2, NOVA1, NRG3 et PRKCE. Ces gènes codent pour des protéines constituant un réseau d’interactions, impliquées dans la plasticité synaptique, et hautement exprimées dans le cerveau et ses tissus associés. De plus, l’analyse des sentiers de signalisation pour les gènes identifiés (P = 0,03) a révélé une induction de mécanismes de Potentialisation à Long Terme.
Les variations des traits étudiés seraient en grande partie liées au sexe et au statut d’hypertension. Pour la consommation de tabac, nous avons noté que le degré et le sens des corrélations avec l’obésité, les traits hémodynamiques et le stress sont spécifiques au sexe et à la pression artérielle. Par exemple, si des variations ont été détectées entre les hommes fumeurs et non-fumeurs (anciens et jamais), aucune différence n’a été observée chez les femmes. Nous avons aussi identifié de nombreux traits reliés à l’obésité dont la corrélation avec la consommation de tabac apparaît essentiellement plus liée à des facteurs génétiques qu’au fait de fumer en lui-même. Pour le sexe et l’hypertension, des différences dans l’héritabilité de nombreux traits ont également été observées. En effet, des analyses génétiques sur des sous-groupes spécifiques ont révélé des gènes additionnels partageant des fonctions synaptiques : CAMK4, CNTN5, DNM3, KCNAB1 (spécifique à l’hypertension), CNTN4, DNM3, FHIT, ITPR1 and NRXN3 (spécifique au sexe). Ces gènes codent pour des protéines interagissant avec les protéines de gènes détectés dans l’analyse générale. De plus, pour les gènes des sous-groupes, les résultats des analyses des sentiers de signalisation et des profils d’expression des gènes ont montré des caractéristiques similaires à celles de l’analyse générale.
La convergence substantielle entre les déterminants génétiques des substances psychoactives, du stress, de l’obésité et des traits hémodynamiques soutiennent la notion selon laquelle les variations génétiques des voies de plasticité synaptique constitueraient une interface commune avec les différences génétiques liées au sexe et à l’hypertension. Nous pensons, également, que la plasticité synaptique interviendrait dans de nombreux phénotypes complexes influencés par le mode de vie. En définitive, ces résultats indiquent que des approches basées sur des sous-groupes et des réseaux amélioreraient la compréhension de la nature polygénique des phénotypes complexes, et des processus moléculaires communs qui les définissent.Links among substance use, obesity, stress and related cardiovascular outcomes may be in part due to shared genetic factors. To investigate this hypothesis, we performed genome-wide linkage and association scans for genetic components of habitual alcohol, tobacco and coffee use, response to mental and physical stress, obesity related anthropometric traits and heart rate (HR) and blood pressure (BP) measurements in 119 multigenerational French Canadian families from founder population of Saguenay-Lac-St-Jean region using 58000 SNPs and 437 microsatellite markers and followed with functional annotation on resulted genes. We found significant phenotypic correlations among substance use, obesity, stress and hemodynamic traits. For instance, alcohol and tobacco users had attenuated HR response to mental stress; moreover, tobacco users had lower BP compared to non users; Hypertensives had stronger HR and systolic blood pressure (SBP) response to mental stress and higher body mass index (BMI), compared to normotensives; Use of tobacco seemed to increase the epinephrine level in body and higher epinephrine level was correlated with lower BMI. Consistent with phenotypic relatedness, we found numerous shared genes associated / linked to substance use, obesity-related traits, response to mental and physical stress and hemodynamic traits including CAMK4, CNTN4, DLG2, DAG1, FHIT, GRID2, ITPR2, NOVA1, NRG3 and PRKCE forming protein interaction network, involved in synaptic plasticity and highly expressed in brain related tissues; moreover, pathway analysis on identified genes pointed (P = 0.03) to Long-Term Potentiation pathway. Large portions of variation of studied traits were explained by sex and hypertension status, focusing on tobacco use we noted that degree and the direction of correlations of obesity, hemodynamic and stress related traits with tobacco use vary according to sex and hypertension status; for instance, while in males, current tobacco users were slender compared to never or former tobacco users, there were no such differences in females; moreover, we found several obesity related traits that their correlations with smoking behavior seemingly root in genetic factors rather than smoking effect itself. Sex- and hypertension differences in heritabilities of many of these traits were also observed; meanwhile, specific subgroup genetic analyses uncovered additional shared synaptic genes among these traits including CAMK4, CNTN5, DNM3, KCNAB1 (Hypertension-specific), CNTN4, DNM3, FHIT, ITPR1 and NRXN3 (Sex-specific) having protein interactions with genes driven from general analysis; moreover, the results of pathway analysis and reported gene expression profiles of resulted genes from subgroup analyses revealed similar characteristics to those from general analysis. The substantial overlap among genomic determinants of substance use, stress, obesity and hemodynamic traits supports the notion that the genetic variations in pathways of synaptic plasticity may be a common interface behind them as well as observed sex and hypertension genetic differences, we also think synaptic plasticity may underlie many complex phenotypes in which life style is a contributing factor; moreover, our findings indicate considering subgroup and network-based approaches enhance understanding of polygenic nature of complex phenotypes as well as shared molecular underpinnings among them.

Texte intégralRésumé :
This chapter considers the research project as a temporary, liminal community, always at risk of dispersal from external incentives and internal frustrations. Participant commitment can be sustained through the traditional mechanism of ritual, while intellectual insight advances in play; junior researchers can animate both modes of sociability and achieve influence thereby. Shared space and shared time coordinate planned interactions and also facilitate spontaneous emergences. Examples from the Göttingen Interdisciplinary Working Group on Cultural Property illustrate the intellectual payoffs of coffee machines, dancing, visual project mapping, and writing the grant renewal application as exercises in social as well as intellectual coordination. In the middle stages of research, a tolerance for conceptual ambiguity at the project level can facilitate lower-level successes and interactions.

Texte intégralRésumé :
Seldom have studies of overseas huiguan, i.e., Chinese benevolent associations, covered their charitable service of repatriating coffins/bones of the deceased from their host countries to their hometowns in China for burial. This peculiar long-standing Chinese “modern tradition,” till the early 1950s, can now be solidly evidenced by the voluminous Tung Wah Coffin Home Archives in Hong Kong after the materials have been made known in recent years. According to the correspondence between the Tung Wah Hospital (a charitable organization itself) and huiguan all over the world, thousands of coffins and boxes of bones were shipped back to native places of most Chinese emigrants from the “Gold Rush” era every year through Hong Kong during the first half of the last century, especially after the Tung Wah Coffin Home was built by the Hospital to house coffins and exhumed bones awaiting shipment. Starting with a mapping of the sending points, this chapter attempts to first delineate the function of Chinese benevolent associations there as key organizations in the charity network of the global Chinese world. The implications of their operation in the historical connection between the host countries and hometowns of overseas Chinese via Hong Kong are also exemplified and explicated.

Texte intégralRésumé :
There are about 2,000 entities in the world today that ethnologists call societies, each with distinct cultures. Perhaps the most obvious marker, and many argue the most important, is that each of these entities has its own language. Among the other societal attributes, besides language, that can make claims to human universality, or nearly so, is the cultural use of psychoactive substances— or what commonly are referred to as simply “drugs.” These range from mild stimulants such as coffee, tea, cacao, coca, and kola to stupeficients such as opium and alcohol, to hallucinogens found in mushrooms, cacti, and a number of flowering plants. Since the Mesolithic and perhaps before, the vast majority of the world’s peoples have used one or more such substances for religious and related purposes. Even in their most seemingly secular contexts, drugs are often used in ritual and habitual ways that exhibit their cultural embeddedness. Increasingly the world’s remaining indigenous peoples and many local folk are confronting questions and the consequences of the production, processing, trade, trafficking, and consumption of drugs deemed illegal and illicit by global agencies and national polities. Some of these substances, usually in their unrefined forms, have deep roots in local and indigenous cultures and economies. Often they serve important roles in constituting and maintaining cultural identity. With ever-increasing modernization and globalization, the circumstances and conditions under which indigenous and local peoples produce, trade, and use these substances continues to change. In turn, psychoactive substances—whether sanctioned, proscribed, or both—often serve as agents in the creation and defense of local and indigenous “moral” geographies. The concept of moral geography (as used here) refers to both the actual and symbolic terrain upon which traditional societies elaborate their customary livelihood and belief systems, and the cognate spaces in which they defend these practices and perceptions. For most indigenous peoples, the drugs in their culture, whether sacred or profane, are manifest in both their moral economies and geographies. For some groups, drugs become defining elements in their relations with dominant cultures and polities. For others, they are less than determinate, but still play significant roles in mediating exchanges—both symbolic and material. In either case, they can serve as mechanisms of subordination, or modes of resistance, or sometimes both.

Dans ASME 2020 Pressure Vessels & Piping Conference. American Society of Mechanical Engineers, 2020. http://dx.doi.org/10.1115/pvp2020-21121.
Texte intégralRésumé :
Abstract Coke drums are critical equipments in delayed coking plants, which are operated under severe thermal-mechanical conditions by cyclic heating and quenching processes. Cracks are usually developed during service because of severe plastic deformation and low-cycle fatigue. Thus, the assessment of the deformation severity and remaining life is important for safety operating of the coke drums. This study investigated the bulging damage and fatigue life of 6 coke drums after 16 years and 22 years of service in China. A thermal-mechanical fatigue test were first performed to simulate complex loading condition experienced by the coke drum. The thermal-mechanical fatigue life curve of the fabrication material was obtained. Then, a internal laser scanning was employed to measure the deformation and bulges of drum shells. The finite element analysis was developed to calculate the cyclic stress and strain and bulging severity based on the laser mapping and operating conditions. The fatigue life of the coke drum was assessed by the Coffin-Manson-Basquin’s relationship. The life evaluation results of different methods were compared and analyzed. The results showed that a reasonable life of the coke drum can be obtained by using the thermal-mechanical fatigue properties and laser scanning approach.
