Повний текст джерелаThirteenth-Century motets composed on the response Stirps Jesse belong to a great exegetical, iconographical and musical tradition well-known as the « Tree of Jesse ». The response, which is possibly composed by Fulbert of Chartres (d. 1028), express the relationships between Mary and her Son. It calls to mind one of the most important Christian believes as the flesh Embodiment of God thanks to the Virgin which is one of the most important Christian dogmas. The Stirps Jesse, or more often the second part of the verse FLOS FILIUS EJUS, is rhythmically organized in order to create a textual and musical polyphony. The melody, the lengths of musical phrases and of the line of the upper part depend intimately on this quotation or tenor. Even if the tenor is of great influence on the polyphony, this study demonstrates that the textual structure of the upper part corresponds to the musical organization in the two-part motets on FLOS FILIUS EJUS in the manuscript W2. The relationships between poem and melody are built on the close connection between the structural organization of the text and of the melody thanks to the melodic patterns (colores), register and rhythms

Повний текст джерелаThe latest IPCC report clearly confirms the climate projections for increasing temperaturesand their variability at the end of the 21st century. The effects of climate changes in fruit yield andquality have been studied in a project funded by INRA (project CAQ40, Metaprogramme ACCAF).Experiments carried out on potted peaches placed in different climates (control, +2 ° C and + 5 ° C),allowed the identification of the processes (phenology, development, growth, photosynthesis,metabolism) most sensitive to rising temperatures and their consequences on the development andcomposition of fruits and the sustainability of production.Higher temperature has increased the demand for water, leading to a decrease in the waterpotential of the trees, which may have led to a concentration of the compounds of interest in thefruit. The reduction of leaf photosynthesis under high temperature conditions was related to theinhibition of photosynthesis by high temperatures and stomatal control related to water status.After flowering, the rise in temperature accelerates the vegetative growth, triggering a more rapidestablishment of leaf area. This early vegetative growth resulted in: (i) very rapid dynamics ofelongation of the axes in long shoot (ii) a more pronounced apical dominance, (iii) a decrease in theaxillary axial branching. In contrast the later heat treatment had an adverse effect on the initiationand differentiation of floral buds reducing the production potential in the following year.In addition, the increase in temperature after flowering resulted in a marked shortening ofthe fruit growth period, with an expected harvest date almost 3 weeks earlier. This shortening offruit growth duration has led to a decrease in the flow of carbon entering the fruit, penalizing itsgrowth and quality. The very different climates between the two experimental years resulted in ahigh variability in fruit composition between the two years of experimentation. In 2014, increasedtemperature during the early stage of fruit development or continuously led to the harvest ofsmaller fruit with higher concentrations and higher sucrose content. In 2015, the time durationbetween flowering and maturity was even shorter than in 2014, which could be linked to thewarmer climate of 2015. In 2015 fruits were less sweet and acidic than those of 2014. However, therise of temperatures at the end of fruit development in 2015 increased the levels andconcentrations of hexoses and sorbitol; this increase was partially due to a concentration effect butalso to an effect on fruit metabolism. Increased temperatures in the middle and at the end of fruitdevelopment also favoured the accumulation of malic and citric acid. The high temperatures did nothave much effect on vitamin C and either increased or decreased the levels of phenolic compounds.The effects of an increase in temperature on the metabolism are therefore very dependent on thestage of fruit development.The use of a Fruit‐scale model and a tree‐level (QualiTree) model could simulate both the effect ofthe environment and cultural practices on the growth and quality of the fruit, and give a moreintegrated view of the plant's functioning under environmental constraints

Повний текст джерелаThe root system is essential but essentially invisible. Plants are anchored to the soil through their root system; their adaptation and survival abilities are highly dependent on their ability to learn to take advantage of the space that surrounds them. Certain trees are nevertheless some of the largest and oldest living species on the planet- evidence of their ability to adapt to changes in their environment. Within managed anthropogenic constraints, particular species are vulnerable. It is clear that a wide range of parameters are likely to influence the root system and its operation, which offers many entry points to improve our understanding of a root's capacity for expansion, its dynamics, its role within the plant itself and within the soil plant atmosphere continuum. Available data on the extent and dynamics of plant roots includes several thousand references. However, the vast majority of these observations were made within the first meter of the soil profile. Data acquisition for the fine and/or deep roots is currently limited by constraints of time and financial resources. To overcome this lack of information, while trying to assess root dynamics under different environmental conditions, many models have been developed. However, it is still difficult to describe the complexity of root development in the community and to integrate its "plasticity".To understand such a complex environment, we must work toward establishing a definition of objectives and the tools necessary to develop and implement them. The work developed in the first part of this thesis is the subject of two articles and focuses on a literature review about deep roots. The vital role of the root system for the plant is well highlighted, as is its impact as a link within the atmosphere. We discuss the role of deep roots in carbon storage, which is critical and often underestimated. The different techniques for accessing the root systems in situ are also considered, and we present our access technique for observing the roots down to depths of five meters. We have also developed tools for shooting through a flatbed scanner and image analysis ( IJ_Rizo ) now available online.In the second part of the thesis, we focus on the study of root systems of adult rubber trees (Hevea brasiliensis L. RRIM 600) in the northeast of Thailand. Thailand has greatly expanded its acreage to extend its operations beyond its natural climate zone, into areas of high water stress. In this context, we studied the seasonality and dynamics of fine roots for three years and their contribution to the carbon cycle. We were able to highlight the continuity of root dynamics during independent periods of defoliation, yet link these to the seasonality of rainfall. We were also able to characterize the low differentiation of root dynamics at 0 to 4.5 m of depth in this context.The third part of the thesis concerns the study of teak particular to the region of Luang Prabang, Laos. By applying the rain exclusion technique for 2 years on a plantation of twenty-year-old trees, we observed the influence of precipitation patterns. During the period of water stress, an almost total cessation of root growth, at the surface and significant depths, has been highlighted. We conclude that in the case of species with a high dependence on water resources there is a direct impact on the physiological state and stagnated trunk growth. Some individuals have demonstrated an ability to adapt by changing their foliation/defoliation cycle, accompanied by a resumption of trunk growth during the second year of imposed drought. We also demonstrated the importance of rooting as a means of carbon storage, which in this context represents more than 45% of total carbon- roughly double the amount published in other literature .The data obtained for the species studied in this paper can be used for modelling scenarios simulating climate change and changing land use

Повний текст джерелаHuman activities are responsible for the atmospheric transfer of several types of compounds among which elements are present. One of the secondary effects of such transfer may be to affect human health and the functionality of ecosystems. After atmospheric transfer, a complex deposition of the elements occurs on the earth surface, with very unequal distribution, accumulation or dilution inducing quite different effects on water and soil composition and on the functionalities of living beings. The deposition process has been studied for approximately half a century on tree trunks. These organs constitute a very common vertical matrix on which quantitative or biomonitoring studies can be efficiently carried out, thus offering widely used routine tests. However, for a better exploitation of the information contained in such deposits, a much better understanding of this type of deposition was required. Such is the purpose of this report. A single tree species was chosen for this study: Fraxinus excelsior L. , a very common tree for our region, which was cultivated in the campus station and which could be found at several altitudes between 200 and 1700 m. Our methodological approach consisted in mixing two types of analytical techniques: ICP-MS and SEM-EDX which allowed to obtain an accurate concentration measurement of trace elements, a determination of their location or distribution at a microscopic scale and a chemical determination of the composition of crystallized or precipitated compounds. The time-scale of our studies on deposits ranged from 3 months to 40 years. Two types of fractions were analysed separately: a superficial one, on the stems, and another one, integrated inside the suber tissue and also inside other tissues. It was demonstrated that the superficial deposit was in fact a component of a specific small ecosystem characterized by a non-negligible photosynthetic rate and by a reviviscent ability. The superficial deposit is submitted to a partial lixiviation by rain. The suber tissue is a waterproof, apoplastic layer able to tightly retain most of the elements over long periods of time. It seems to be the best tissue for retaining atmospheric components over several decades. The deposit has several possible origins geogenic, biogenic or anthropogenic. In order to focus on this last fraction, a new system of calculation was conceived, which allows to determine the composition of an atmospheric anthropic elements fraction (AAEF). Moreover, this AAEF was fractionated into two parts, a dispersed one inside the deposit and a pattern of solid particles which were found either in the superficial deposit or inside the suber but not in the other tissues. A purification of the solid particles fraction was carried out, separating the water-soluble elements, the HNO3 2N-soluble ones and the solid residue. This last fraction contains most of the geogenic components, and of the Pb and Mn contents. The HNO3 fraction concentrates the elements such as Zn and Cu. The main purification steps are associated to the presence of the whole stock of dispersed K and Na inside the water phase and of Ca in the HNO3 fraction. This fractionation probably allows interesting speciation studies. With all these new experimental approaches, it seems possible to obtain realistic analyses of the historical and geographical distributions of elements deposits on different spatial scales

This study investigated cross-domain applications used to bridge information technology and the Public Procurement Act. Through indirect reference to the literature and logical reasoning, it was found that the relationship between the two entities is complementary and requires further research. This study employed a decision tree model to parse the long, complicated provi-sions within the Public Procurement Act, focusing on cross-domain applications. We established a logical framework of classification and quantification that would enable government organizations to select the correct method when calling for bids in pro-curement cases. It was found that although this approach is applicable under normal work condi-tions, a number of special cases still require manual correction. We discovered that the selection of bids is determined by the individuals in charge as well as factors under con-sideration, such as time of delivery, price, the expectations of superiors, and the adapta-bility of suppliers. Each of these factors varies from case to case, resulting in differences in the derived frameworks. Disturbance variables such as the work attitudes of personnel, assigned tasks, and dedication of suppliers also have a strong influence on the selection of bids.
