Повний текст джерелаEmbedded systems in aircraft must comply with the requirements of mass, volume and cost. The active modules of electronic scanning antenna are, in this context, a strategic challenge in terms of mass, volume and reliability. Today, there are up to 1000 modules per antenna, each one containing a circulator-isolator in order to guarantee its performances. The technology of ferrite circulators and isolators remains the most efficient in terms of isolation and insertion losses. It is also fully passive as no external energy is required to work. However this technology is expensive due to complex mechanical assembling of the different materials: magnetic and dielectric ceramics, magnets, conductors made of copper and soft metallic material. The integration of such devices also requires the reduction of dimensions without increasing losses for power levels that can be high. Based on by multilayer ceramic components (capacitors and inductors) as well as Low Temperature Cofired Ceramics (LTCC) technology, a new way of manufacturing these components, is investigated in this PhD work.. The idea is to be able to cofire the heart of the component which is the most difficult to adjust and also determines the final volume. The ferrites which currently constitute the core of the circulators are ferrimagnetic garnets synthetized by using a conventional ceramic process and sintered at high temperature (> 1400°C). To make them compatible with LTCC technology, it is essential to reduce their sintering temperature. The targeted temperatures must be less than 1000°C in order to cofire with gold metal parts and, if possible, close to 900°C for circulators with silver. In this context, the objective of this PhD work was to develop a ferrimagnetic garnet for microwave applications with sintering temperatures close to 900°C. This ferrite was then used for the preparation of microwave circulators which are essential components in radar and telecommunications systems. In addition, studies of optimization of the magnetic and dielectric properties have also been carried out to meet the operating requirements (frequency band and power level)

Повний текст джерелаThe Garner Valley site in California is a seismic, geotechnical and structural instrumented site. The structural recordings on the test structure provides data for soil-structure interaction studies. Soil structure interaction is the phenomenon that differentiate the response of a structure based on an perfectly rigid foundation within a perfectly rigid soil, from the response of a structure in reality. In order to analyse soil-structure interaction effects on the Garner Valley test structure, using the substructure analysis method, geotechnical and structural parameters which are necessary for the constitution of the foundation impedance function are analysed by a dynamic parametric analysis of the soil column under seismic load, using uniaxial linear equivalent model, from seismic and geotechnical in-situ data. The shear modulus reduction and hysteretic damping of the soil are therefore found and can be used in combination with geometrical and geotechnical data to calculate the springs and dashpots equations, used as solutions for the foundation impedance function needed in the substructure approach. The small size of the foundation at Garner Valley allows the non-rotational and non-torsional foundation hypothesis. Springs and dashpots are then implemented in addition of the fixed base model, horizontally and vertically. Kinematic interaction is also studied, even though the foundation size is small and the difference between foundation input motion and free field motion are minimal, the use of foundation input motion as input reduces maximum acceleration on top of the structure. This reduction matches the in-situ levels of maximum acceleration when the foundation is flexible, using springs and dashpots. The results of inertial interaction, period lengthening and damping increase, are also noticed, and compared to theoretical results.

In this master thesis we study experimentally the longitudinal spin Seebeck effect (LSSE) in bilayers made of a ferromagnetic insulator (FMI) and a metallic layer (M). We also present a theoretical model based on the spin current density ⃗ Js carried by a non-equilibrium magnon distribution, generated by a thermal gradient ∇T across the thickness of the FMI. When ⃗ Js reach the FMI/M interface it is pumped towards the M layer due to conservation of the angular momentum, so, the M layer is essential for the LSSE existence. Here the FMI consists of a Yttrium Iron Garnet (YIG) lm, grown over a Gadolinium Gallium Garnet (GGG) substrate. Different metallic materials were used as the M layer i.e. Pt and Ta that have normal behavior and Py that is a ferromagnetic metal (FMM). The experimental procedure consists of systematic measurements of the electric voltage VISHE, produced by ⃗ Js through the Inverse Spin Hall Effect (ISHE) in the normal metal or (FMM) layer. In YIG/Pt measurements were done in the temperature range from 20 to 300 K. The experimental data are tted to the proposed model for the LSSE and good agreement is obtained. The results shows that the Py and Ta can be used to detect the LSSE with the ISHE. The results of this master thesis have strong interest in the area of spin caloritronics helping to the development of the eld and to raise possibilities of new spintronic devices. ----- Nesta diserta ção e estudado experimentalmente o Efeito Seebeck de Spin Longi- tudinal (LSSE), em bicamadas formadas por um isolante ferromagn etico (FMI) e um lme metalico (M). Tamb em foi desenvolvido um modelo te orico baseado na den- sidade de corrente de spin ⃗ Js que existe quando uma distribui c~ao de m agnons fora do equil brio e gerada por um gradiente t ermico ∇T aplicado na sec ção transversal do FMI. Quando ⃗ Js chega na interface FMI/M e bombeada para a camada M satis- fazendo a conserva ção do momentum angular, assim que a camada NM e essencial para ter um LSSE. Como camada FMI foi utilizada a granada de trio e ferro (YIG) crescida num substrato de (GGG). Diferentes materiais metalicos foram utilizados como camada M, sendo Pt e Ta paramagn eticos e o Py ferromagnetico. O proced- imento experimental consiste na medi c~ao sistem atica da voltagem el etrica VISHE, que e produzida por ⃗ Js por meio do efeito Hall de spin inverso (ISHE) que ocorre na camada M. As medidas em YIG/Pt foram feitas numa faixa ampla de temperatura de 20 a 300 K. Os dados experimentais são fi tados com a teoria proposta para o LSSE encontrando-se boa concordância. Nossos resultados mostram que o Py e o Ta s~ao bons candidatos para detec ção do LSSE. Esta disserta ção e de grande interesse na area da caloritrônica de spin, ajudando no desenvolvimento deste campo e na concep ção de novos dispositivos tecnol ogicos baseados na spintrônica.

Повний текст джерелаSouth American species of Viguiera were transferred to the genus Aldama based on molecular studies. However, the circunscription of Aldama tenuifolia (Gardner) E.E.Schill. & Panero and A. kunthiana (Gardner) E.E.Schill. & Panero, belonging to Section Paradosa, series Tenuifolieae, is not yet well established because these species are morphologically very similar. The aim of the present study was to analyze the anatomy of the vegetative organs and the yield and chemical composition of essential oil of these species in order to provide data to help in their circumscription. For anatomical analyzes, leaves, aerial stems, xylopodia and roots from three individuals of each species were fixed in FAA 50 or in Karnovsky solution, infiltrated in hydroxyethyl methacrylate, sectioned with a rotary microtome, stained and mounted in synthetic resin. Histochemical tests were also performed on fresh or fixed material embedded or not in hydroxyethyl methacrylate. The analysis of the leaf surface was performed by light microscopy using the technique of dissociation of the epidermis and by scanning electron microscopy using the usual procedures of preparation. The extraction of essential oil (EO) was performed by hydrodistillation in a Clevenger-type system, separately for each organ of each species. Essential oils (EO\'s) were analyzed by Gas Chromatography coupled to Mass Detector with samples in 20mg/mL concentration in ethyl acetate. The anatomical study showed that the leaves of the two species differ in the outline of the epidermal cell wall in front view side and in the occurrence of secretory canals in primary phloem and ground parenchyma of the midrib. In relation to the stem, the most remarkable difference was the occurrence of secretory canals in the primary and secondary phloem and in relation to the root was the degree of cambial activity participation in tuberisation process. The highest OE\'s yields were verified to the underground organs. For the leaves, xylopodia and roots of both species, the same major compounds were found, varying only the relative percentages. In addition, unique compounds (?-phelandrene, ?-patchoulene, ?-isocomene and longifolene-(V4) for A. tenuifolia and cyperene for A. kunthiana) were also identified that can, along with the compounds common to all two species, provide a characteristic chemical profile for each of these species. Therefore, the studies of the anatomy and of the chemical composition of OE\'s of the vegetative organs of A. tenuifolia and A. kunthiana, which are considered morphologically very similar, may help differentiate these species.

Повний текст джерелаThe Mayombe belt is the congolese part of the Araçuaï-West Congo belt system which extend from eastern margin of Brazil to western margin of central Africa. It runs parallel to the Atlantic coastline with NW-SE trend. Considering geochronological data, it is subdivided into two lithostratigraphic domains : (i) the Paleoproterozoic domain and (ii) the Neoproterozoic domain. The Paleoproterozoic domain of the Mayombe range corresponds to the inner part of the belt and is characterized by the coexistence of para and orthoderived rocks deformed and metamorphosed to varying degrees. These rocks are distributed among the three main lithological Groups : (i) the Loémé Group, (ii) the Loukoula Group and (iii) the Bikossi Group. Structural analysis of Loémé and Loukoula Groups shows folded and fractured stuctures. In the Loémé Group, folds trend NE-SW, NNE-SSW and N-S while in the Loukoula Group, the main shortening trends NE-SW. The Bikossi Group is characterized by folds oriented in the directions identified in the preceding Groups. The geochemical study carried out on samples from the Paleoproterozoic domain of the Mayombe belt shows that the latter is heterogeneous, by involving rocks of various origin and lithology. The petrological characterization of Loémé and Loukoula Groups shows that they are affected by at least two distinct metamorphic events that overlap. The first event is characterized by garnet-biotite-oligoclase parageneses in metapelites and by the development of brown hornblende in metabasites, thus allowing the evolution context to be situated in the amphibolite facies. The second event is recorded differently in Loémé Group and Loukoula Group. It consits respectively in garnet-biotite-oligoclase assemblages in the Loemé Group and in chlorite-albite-epidote paragenesis in the Loukoula Group. Samples from Bikossi Group present only traces of a single metamorphic event marked by garnet-biotite-muscovite and garnet-chloritoid-chlorite parageneses whose temperature is estimated at 510-568°C for 8 kbar of pressure. U-Pb dating of zircons allows to : (i) define the Archean-Paleoproterozoic (3300-1500Ma) sources of metasedimentary rocks (ii) confirm Paleoproterozoic (2070-2040 Ma) age of Eburnean magmatism and Neoproterozoic (925 Ma) Mfoubou and Mont Kanda type magmatism and (iii) to highlight the perturbations of zircons U-Pb isotopic system at 642 ± 36 Ma and 539 ± 18 Ma. The 40Ar-39Ar analyzes on biotite, muscovite and amphibole from samples of the western domain of Mayombe betl provided since the age range of Pan-African tectono-thermal event at 615-496 Ma

Повний текст джерелаFor a reader of medieval narratives the literary of the scenery, is in the first place an imaginary experience introduced by the act of reading and only subsequently it serves the role of an instrument necessary to reconstruct the image. In the present study, I discuss and reflect upon the natural and architectural elements of description and also the visions of the scenery recurrent in the medieval novel. The medieval language is extremely efficient in its descriptions of subject. The stereotypes are ever present, though punctuated by beautiful, short, yet vivid, descriptions of castles and cities. The elements of the landscape at times form a coherent panoramic setting for the action. Brief descriptions and mentions of the elements of the scenery, both natural and urban, appear as they are called for by the narrative. Such short indications appear to best show the reality of the castles or cities of XII and XIII century

Повний текст джерелаMost species have been subjected to environmental changes during their evolutionary history. However, due to human activity, environmental changes are currently occurring at higher speeds and on a greater scale, presenting new challenges for many species. Pollution, as a major type of human-induced environmental change, may not only affect physiology but also behaviour, thereby affecting population dynamics and consequently biodiversity. The topic of my dissertation is the effect of turbidity from quarrying on the behaviour and social association pattern of the guppy (Poecilia reticulata). Turbidity impairs the fish’s ability to use visual cues during social interactions, which in turn helps increases efficiency of foraging and avoiding predators. I investigated the initial re-sponse of guppies to turbidity and subsequently tested whether turbidity-experienced vs turbidity-inexperienced populations differ in their social association patterns and how they cope with ecological challenges. Both lab-reared and wild-caught guppies that were inexperienced with turbidity reduced social associations in turbid water in con-trast to turbidity-experienced fish. A Markov chain analysis revealed that lab-reared guppies increased associations with particular neighbours. Similarly, wild-caught gup-pies maintained the number of initiated associations under turbid conditions. The in-crease in non-initiated associations suggests a stronger connectivity within the shoal, leading to higher information transmission in a poor visual environment. Additional results showed that this altered social structure enabled turbidity-experienced fish to maintain the frequency of mating attempts in turbidity and to avoid predation risk. This suggests that guppies have the ability to adjust to turbidity, but with major changes in their social structure, which might have an impact on population dynamics.

Повний текст джерелаA geological investigation of the Port Nolloth metasediments in the central external parts of the Gariep Beit has led to a re-interpretation of tbeir lithostratigraphy and Pan-African geotectonic evolution. During the rifting stage of passive continental margin evolution, the basal elastic Stinkfontein Sequence was deposited in an alluvial fan environment. Fluviatile conglomerates and quartz arenites (Lekkersing Formation) interfinger with feldspathic arenites and minor volcanics (Vredefontein Formation), and prograde into marginal marine elastics and carbonates (Gumchavib Formation). Rift faulting produced local grabens into which massflow sediments (Kaigas Formation) and volcaniclastics (Rosh Pinah Formation) were shed. During the sea-floor spreading stage, a shallow-water carbonateclastic unit, the Hilda Sequence, was deposited. Conglomerates, quartzites, and schists with resedimented gravity-flow characteristics (Wallekraal Formation) are sandwiched between lower and upper platform carbonates (Pickelhaube and Dabie River Formations). The Hilda is unconformably overlain by the Numees Sequence, consisting of a widespread glaciogenic diamictite (Sendelingsdrif Formation) and a near-basal banded iron formation (Jakkalsberg Formation). A deep-water elastic unit, the Holgat Sequence, was laid down during the early stage of the lower Nama transgression.

Повний текст джерелаIn Modern Era, Provence and Dauphiné were quite far from the French royal power and appeared to be unique when it comes to human-wolf relationship. The demographic evolution of 16th-18th centuries led to a strong pressure on the environment resulting in a mosaic of diverse agricultural landscapes. The forest areas were reduced while the increasing hunting pressure drove to a reduction of natural preys’ populations. Wolves were obliged to get closer to human and livestock in order to subsist. If the image of the wolf in the ancient hunting and agronomic books was dreadful, it appears that the inhabitants were able to coexist with this animal willy-nilly. However, conflicts appear very intense in some places. Attacks on humans demonstrate the vulnerability of some social groups whose practices are closely related to the pastoral economy linked to the agronomic landscapes. These nuisances associated with canine rabies transforming the wolf into a violent victim contributed to the emergence of an ambivalent relationship. Apart from some more or less violent episodes belonging to the crime news, the continuous relationship was quite commonplace, and a certain reciprocity even took place. Indeed, through hunting bounties granted by local institutions, and despite the national policy, residents were able to participate to wolves culling. This hunt offered the opportunity to fight against the wolf in order to respond to the nuisance, but also to reduce its population in order to reduce the risk

Повний текст джерелаRoot systems at 1900, 2400 and 3000 m of a south Ecuadorian montane forest were investigated. The aim of this study was to improve our knowledge on the impact of altitude on the root functions nutrient acquisition, anchorage and storage of C and nutrients in root biomass. At 2400 and 3000 m, the decrease of root length densities (RLD) with increasing soil depth was more pronounced than at 1900 m. The vertical distribution of N uptake was similar to the vertical distribution of RLD. Thus, the ability for nutrient uptake was more concentrated to the organic surface layer at high altitudes than at 1900 m. Foliar nutrient concentrations showed that plant growth at 1900 m was not limited by nutrient deficiency. In contrast, at 2400 and 3000 m especially N, but also P, S and K limited plant growth. The decreased nutritional status of plants at high altitudes was caused by low mineralization rates of nutrients as well as low ability for nutrient acquisition from deeper soil layers. At 3000 m, root biomass was higher than at low altitudes. Hence, the importance of root systems for C sequestration increased with increasing altitude. Similarly, pools of N, S, K, Ca and Mg were higher at 3000 m than at 1900 and 2400 m. At all altitudes, coarse root systems of trees showed traits that are supposed to improve anchorage. At 3000 m, root soil plates were more superficial than at 1900 m. Root traits that improve the horizontal extension of root soil plates were more pronounced or occurred more often at 3000 m than at 1900 m. It is concluded that impeded rooting in deeper soil layers at high altitudes decreased both the ability for nutrient acquisition and anchorage. At high altitudes, the high allocation of biomass to the root systems showed that at these sites, environmental conditions enhanced the requirements to the functions of roots.

Cerrado rupestre is a subtype of arboreal-shrub vegetation that occurs in rupestrian and rocky habitats. Trichogonia eupatorioides (Gardner) R. M. King & H. Rob belongs to the tribe Eupatorieae of the family Asteraceae, and it is endemic to Brazil. Given the scant knowledge of the botanical traits of this species, the present study aimed to describe the morpho-anatomy of leaves and stems, characterize and identify developmental stages of glandular trichomes, detect the presence of metabolites by phytochemical screening, and determine the composition of the essential oil from aerial vegetative and reproductive parts of T. eupatorioides from a cerrado rupestre area. Samples of T. eupatorioides were collected from the Biological Reserve “Prof. José Ângelo Rizzo” of Universidade Federal de Goiás (UFG). Fully expanded leaves, stems, stem apices, flowers and involucral bracts were used for the morpho-anatomical study and to describe glandular trichomes. Aerial vegetative and reproductive organs were used for the phytochemical study. T. eupatorioides shares anatomical traits with other species described in the literature, such as amphistomatic leaves, anomocytic and anisocytic stomata, epidermal cells with sinuous anticlinal walls and thick external periclinal walls, glandular and non-glandular trichomes, endodermis with starch and Casparian strips, fibers associated to the vascular bundle, and secretory ducts. The glandular trichomes secrete essential oils and phenolic compounds and may be uniseriate or biseriate. The differentiation of the glandular trichomes begins with the expansion of a protodermal cell. The first division is anticlinal for biseriate trichomes, and periclinal for uniseriate ones. The phytochemical screening identified flavonoid and cardiac glycosides and coumarins. Twenty components of the essential oil were identified; of these, 95% were sesquiterpenes. The major components were the sesquiterpenes 3,5-muuroladiene (39.56%), butylated hydroxytoluene (13.07%), and (E)-caryophyllene (5.63%).
O Cerrado Rupestre é um subtipo de vegetação arbóreo-arbustiva que ocorre em ambientes rupestres e rochosos. Trichogonia eupatorioides (Gardner) R. M. King & H. Rob é uma Asteraceae, da tribo Eupatorieae e é endêmica do Brasil. Tendo em vista que a espécie é pouco conhecida sob ponto de vista botânico, o presente estudo teve como objetivo descrever a morfoanatomia da folha e caule de T. eupatorioides ocorrente em área de Cerrado Rupestre, caracterizar e identificar etapas do desenvolvimento dos tricomas glandulares, bem como detectar a presença de metabólitos por prospecção fitoquímica e determinar a composição do óleo essencial em seus órgãos reprodutivos e vegetativos aéreos. Amostras de T. eupatorioides foram coletadas na Reserva Biológica da Universidade Federal de Goiás “Prof. José Ângelo Rizzo”. Para o estudo morfoanatômico e para a caracterização dos tricomas glandulares foram utilizadas folhas completamente expandidas, caules, ápices caulinares, flores e brácteas involucrais. O estudo fitoquímico foi realizado em órgãos aéreos vegetativos e reprodutivos. T. eupatorioides apresenta características anatômicas comuns à outras espécies citadas na literatura como folha anfiestomática, estômatos anomocíticos e anisocíticos, células epidérmicas com paredes anticlinais sinuosas e periclinais externas espessas, tricomas glandulars e tectores, endoderme com amido e estrias de Caspary, fibras associadas ao feixe vascular, e ductos secretores. Os tricomas glandulares são unisseriados e bisseriados e secretam óleos essenciais e compostos fenólicos. A diferenciação dos tricomas glandulares inicia-se com a expansão de uma célula protodérmica; nos tricomas bisseriados a primeira divisão desta célula é anticlinal e no unisseriado é periclinal. Na prospecção fitoquímica foram identificados heterosídeos flavonóides, heterosídeos cardioativos e cumarinas. Foram identificados vinte componentes do óleo essencial, 95% destes são sesquiterpenos. Os compostos majoritários foram os sesquiterpenos 3,5 -muuroladieno com 39,56%, Hidroxitolueno butilado com 13,07%, e o E-cariofileno com 5,63%.

Повний текст джерелаThis dissertation investigates different social functions of agriculture as well as landscape aesthetics in farming systems of different agricultural structures. Throughout the whole project farming systems dominated by small family farms and large-scale farming systems dominated by commercial non-family farms (e.g. cooperatives) were compared. Farmers’ work satisfaction and their connection to the local community were examined in the small-scaled Swiss system and in the larger scaled Northeast (NE) German one. Public landscape preferences were derived using choice experiments in Switzerland and South Germany, representing small-scale systems, as well as in East Germany, representing a large-scaled one, to explore agriculture‘s aesthetic function. Swiss farmers are more satisfied with their agricultural work if for effects of farm structure (e.g. farm size) is controlled for. Farm income plays a significantly more important role for the work satisfaction of NE German farmers than for that of Swiss ones. Especially for Swiss farmers, farm diversification plays an important role, for example through a diversity of production lines or through non-agricultural activities like agrotourism. Further results show that Swiss farmers and farmers of smaller farms are more connected to their local communities through more locally focused social networks. Farmers of larger farms have their networks farther away from the farm and a weaker sense of belonging to their local community. A biographical bond to the farm also strenghtens the connection to the local community. Concerning public landscape preferences the majority of the Swiss and East German respondents generally prefers qualitative changes to landscapes (i.e. meadows for free range animal husbandry, meadow orchards and more biodiversity). Forest loss or changes in plot sizes of agricultural land and forests are nearly uniformly rejected in all regions.

Повний текст джерелаLittoral macroinvertebrates are an important biotic component of lakes by contributing substantially to the biodiversity and functioning of lake ecosystems. Humans alter the littoral and riparian areas for various purposes, but the resulting ecological impacts on littoral macroinvertebrates have not been quantified. In this thesis, I investigated the significance of key environmental factors for littoral macroinvertebrate communities and how human alterations of these environmental factors impact the structure and function of macroinvertebrate communities. Macroinvertebrate community composition was significantly related to littoral structure, trophic state and the hydrodynamic regime. The significantly higher compositional dissimilarities among habitats than among trophic state suggested that littoral structure was the more important driver of community composition. Structural degradation caused a significant reduction of habitat heterogeneity and resulted in a significant reduction of species diversity and a significant altered community composition. This caused a significant reduction of macroinvertebrate food web complexity and substantial alterations of the trophic base of the food webs. Climate-change induced water level fluctuations resulted in the loss of root habitats and the specific community associated with this habitat. Ship-induced waves had substantial direct effects, since macroinvertebrates were detached from their habitats by waves even at moderate shear stress levels. However, the impacts of water level fluctuations and ship-induced waves were mitigated by the presence of habitats with high structural complexities. This thesis provided a mechanistic understanding of how human activities alter relationships between environmental factors and biotic communities. This knowledge can be used to develop scientifically sound approaches to assess the persistent human impacts on lake ecosystems.

Повний текст джерелаAutomatic identification of multiword expressions (MWEs) is a pre-requisite for many natural language processing applications. This task is challenging because MWEs, especially verbal ones (VMWEs) like to kick the bucket (which means to die), exhibit surface variability (no buckets were kicked ). However, compared with regular constructions, this variability is usually more restricted (e.g. some nouns cannot be modified by an adjective), hence various variability profiles. We address here a subproblem of VMWE identification, namely the identification of occurrences of VMWEs previously seen in corpora, whatever their surface form, which requires to take ambiguity into account to avoidliteral (he kicked the old bucket) or coincidental occurrences (he kicked the ball and the bucket fell down). To this end, we considered two main approaches : The first one is based on a language independent measure of VMWE variability. The second one consists in modeling the problem as a classification task on the basis of features relevant to the VMWE morphosyntactic variability, which led to a system (VarIDE) that participated in the PARSEME shared task on automatic identification of VMWEs in 2018

Повний текст джерелаVertical mixing in the ocean contributes to sustain the Meridionnal Overturning. Circulation (MOC) by allowing the renewal of deep waters. A section across the MOC is performed by the hydrological radial OVIDE repeated every two years between Portugal and Greenland since 2002. The energy required for mixing is provided by internal waves generated by wind and tides and micro-structure measurements(VMP) in 2008 show intensified values of dissipation Evmp in the main thermocline and near topographies. Our study is based on these observations and aims tostudy the vertical fine-scale structure of the ocean. Estimates of the dissipation E due to internal waves are made with CTD and LADCP measurements. The comparison with VMP measurements allow us to optimize the parameterization of E by framing the observations by factor 3 and their mean values at ±30%. The systematic application to the OVIDE dataset provides a mapping of the mixing across the basin. Geographical distribution of the vertical diffusion K is similar along the five sections, with values near10−4m2/s in the main thermocline and at the bottom of topographies, and near 10−5m2/s in the ocean interior. Regional differences are present and K can belocally close to 10−3m2/s. Application to FOUREX1997 datas et reveals an increase of K along the Mid-Atlantic Ridge, where the average values are 2 to 3stronger than along OVIDE sections. The spatial distribution of Thorpe scales LT appears to be correlated with internal waves mixing patterns. Nevertheless dissipation estimates based on LT overestimates Evmp by a 10 to 100 factor, which maybe due to misrepresentation of the stage of turbulence development in the ocean. Some mechanisms that can generate internal waves are proposed. Probable sites where tidal generation could occur are located using a simple model of wave beam trajectory. A possible correlation between geostrophic flows and internal waves is considered in the main thermocline. Finally the study of Turnerangles shows that double-diffusion instabilities may bepresent over a large part of the section
