Texte intégralRésumé :
The northward-flowing Humboldt Current hosts perpetually high levels of productivity along the western coast of South America. Here, we aim to elucidate the deep-time history of this globally important ecosystem based on a detailed palaeoecological analysis of the exceptionally preserved middle–upper Miocene vertebrate assemblages of the Pisco Formation of the East Pisco Basin, southern Peru. We summarise observations on hundreds of fossil whales, dolphins, seals, seabirds, turtles, crocodiles, sharks, rays, and bony fishes to reconstruct ecological relationships in the wake of the Middle Miocene Climatic Optimum, and the marked cooling that followed it. The lowermost, middle Miocene Pisco sequence (P0) and its vertebrate assemblage testify to a warm, semi-enclosed, near-shore palaeoenvironment. During the first part of the Tortonian (P1), high productivity within a prominent upwelling system supported a diverse assemblage of mesopredators, at least some of which permanently resided in the Pisco embayment and used it as a nursery or breeding/calving area. Younger portions of the Pisco Formation (P2) reveal a more open setting, with wide-ranging species like rorquals increasingly dominating the vertebrate assemblage, but also local differences reflecting distance from the coast. Like today, these ancient precursors of the modern Humboldt Current Ecosystem were based on sardines, but notably differed from their present-day equivalent in being dominated by extremely large-bodied apex predators like Livyatan melvillei and Carcharocles megalodon.

Texte intégralRésumé :
The Pisco-Ica and Sacaco basins of southern Peru are renowned for their abundance of exceptionally preserved fossil cetaceans, several of which retain traces of soft tissue and occasionally even stomach contents. Previous work has mostly focused on odontocetes, with baleen whales currently being restricted to just three described taxa. Here, we report a new Late Miocene rorqual (family Balaenopteridae), Incakujira anillodefuego gen. et sp. nov., based on two exceptionally preserved specimens from the Pisco Formation exposed at Aguada de Lomas, Sacaco Basin, southern Peru. Incakujira overall closely resembles modern balaenopterids, but stands out for its unusually gracile ascending process of the maxilla, as well as a markedly twisted postglenoid process of the squamosal. The latter likely impeded lateral (omega) rotation of the mandible, in stark contrast with the highly flexible craniomandibular joint of extant lunge-feeding rorquals. Overall, Incakujira expands the still meagre Miocene record of balaenopterids and reveals a previously underappreciated degree of complexity in the evolution of their iconic lunge-feeding strategy.

Texte intégralRésumé :
Ica Aquifer located at the coastal zone of Ica River Valley, supplies 40% of the water to a number of farms of Ica Region which is one of the most productive valley of Peru that covers an area of 30,000 hectares of area, in which a diverse agricultural product are grown for local and external market. In the last 15 years, water-table of the aquifer was lowering at an elevated rate that concerned to farmers and authorities of the Peruvian Government, so a number of studies was carried out to increase the water supply to the agriculture areas.The main purpose of the study using isotope techniques, was to have a first insight of the hydrodynamics of Ica, Villacuri and Lanchas Aquifers and the possible interconnection between them and with Pisco River. For such purpose, 31 wells, lakes, rivers and springs of Ica and Pisco Basin where sampled during the years 2014 to 2016 both in rain and dry seasons, getting 189 samples for isotope and chemical analysis. The sampling schedule didn’t include rain sampling, instead of it, selected springs were sampled and nearby basin rain data was used.18O,2H and 13C stable isotopes and 3H, 14C radioactive isotopes of the water samples were analyzed in the laboratory of “Isotope Tracer Technologies INC”; the results of the stable isotope analysis confirm the hydraulic interconnection of the three aquifers mentioned above; it also was confirmed that the main source of recharge was provided by Ica River and evidences were found about the contribution of Pisco River in the recharge of Villacuri and Lanchas Aquifers.Analysis of 14C reveals that some wells are overexploited. All the results of 3H analysis were out of range, so it was not useful for the conclusions of the study, and a new sampling of water is required; the reason of this out of range result should be the possible contamination of the samples with no environmental Tritium.

Texte intégralRésumé :
Le formazioni mioceniche di Chilcatay e Pisco del Bacino Orientale di Pisco affiorano nel Deserto di Ica (Perù). Queste formazioni sono caratterizzate da una concentrazione di fossili di vertebrati marini eccezionalmente conservati, in particolare cetacei. Questa tesi ha come scopo effettuare studi cronostratigrafici e tafonomici in queste formazioni esposte sulla sponda occidentale del fiume Ica.
Nonostante il crescente interesse per la fauna a vertebrati delle formazioni di Chilcatay e Pisco, un’esauriente quadro cronostratigrafico non è mai stato realizzato. In questa tesi viene proposta una ricostruzione cronostratigrafica di entrambe le formazioni, grazie all’applicazione dei metodi di tephra fingeprinting, datazioni Ar-Ar, biostratigrafia e stratigrafia a isotopi dello stronzio. La Formazione Chilcatay è stata divisa in due allomembri, Ct1 e Ct2. L’associazione a vertebrati della facies Ct1a nella località di Ullujaya è costituita da una comunità costiera dominata da mesopredatori di acque temperato-calde. La cronostratigrafia è stata ricostruita grazie all’integrazione di risultati biostratigrafici e isotopici che attribuiscono la Formazione Chilcatay al Burdigaliano. Basandosi sulle datazioni Ar-Ar, la deposizione è avvenuta tra i 19.25 e i 18.02 Ma, anche se la biostratigrafia a diatomee indica un’età leggermente più giovane per il top della formazione (17.08 Ma). La Formazione Pisco è divisa in tre allomembri, P0, P1 e P2. Il contenuto di vertebrati fossili dell’allomembro P0 è ancora da caratterizzare, ma si differenzia chiaramente dalla fauna dell’allomembro P1, in cui dominano cetoteridi di media taglia. Nell’allomembro P2, invece, l’associazione è dominata da balenotteridi. La ricostruzione della cronostratigrafia è stata possibile grazie a diversi metodi. Analisi degli isotopi dello stronzio su carbonati e fosfati attribuiscono l’allomembro P0 al Langhiano – Serravalliano. Le datazioni Ar-Ar e la biostratigrafia a diatomee attribuiscono l’allomembro P1 al Tortoniano (tra 9.46 e 8.60 Ma) e l’allomembro P2 al Tortoniano – Messiniano (tra 8.39 e 6.71 Ma). Il metodo del fingerprinting applicato ai tefra ha permesso di ottenere una ricostruzione stratigrafica ad alta risoluzione per P2 e di correlare successioni esposte in diverse località.
La conservazione di vertebrati e invertebrati lungo questa successione è considerata eccezionale. La tafonomia degli invertebrati è stata studiata attraverso microscopia ottica ed elettronica a scansione e catodoluminescenza. Nella Formazione Chilcatay, i gusci dei molluschi sono prevalentemente costituiti da calcite e presentano una buona conservazione. Gli ostreidi, in alcuni casi, mostrano un livello prismatico perfettamente conservato e una luminescenza bassa ed omogenea, che testimoniano un basso grado di alterazione. Questi esemplari sono stati scelti per studi cronostratigrafici con gli isotopi dello stronzio. Studi tafonomici sulle facies a balani della Formazione Chilcatay indicano un ambiente di acque relativamente basse e un ambiente ad alta energia. Nella Formazione Pisco, i molluschi sono solitamente costituiti da calchi di gesso o modelli interni di dolomite/gesso. I rapporti isotopici dello stronzio indicano che la dolomite si è formata tramite diagenesi precoce, mentre il gesso deriva da salamoie pre-mioceniche in risalita. La tafonomia dei vertebrati mostra che le ossa della Formazione Chilcatay hanno un buon grado di conservazione, risultato di un’alternanza di condizioni anossiche e ossiche-disossiche al fondo, testimoniata da analisi sulla distribuzione granulometrica di framboidi relitti di pirite nel sedimento. Nella Formazione Pisco, il calcolo dei tassi di sedimentazione suggerisce che la buona conservazione dei reperti non è dovuta al rapido seppellimento, ma al precoce attuarsi di processi anossici che hanno permesso la fosfatizzazione e la formazione di noduli carbonatici.Along the western side of the Ica River (Ica Desert, Peru), the Miocene Chilcatay and Pisco formations of the East Pisco Basin crop out. These units are characterized by an extraordinarily preserved marine vertebrate fossil fauna, especially cetaceans. This dissertation has the purpose of making chronostratigraphic and taphonomic studies on these formations, cropping out in the western side of the Ica River. Despite the growing significance of the vertebrate fauna of the Chilcatay and Pisco formations, a comprehensive stratigraphic framework has not been established for a long time. Using tephra fingerprinting, Ar-Ar dating, biostratigraphy and strontium isotope stratigraphy, the chronostratigraphy of both the units is here proposed. The Chilcatay Formation is divided into two unconformity-bounded allomembers, designated as Ct1 and Ct2. The vertebrate assemblage in the Ct1a facies of the Ullujaya locality comprises a coastal community, dominated by mesopredators representative of a warm-temperate, sheltered embayment connected with riverine and open-ocean environments. The chronostratigraphic framework is well constrained by integration of biostratigraphic data and isotope geochronology and suggests a Burdigalian age. The time constrains are 19.25 and 18.02 Ma for the Ar-Ar dating on tephra, in agreement with the Sr isotope analyses in Ct1a suggesting Burdigalian ages, even the diatom biostratigraphy suggests a slightly younger age for the top of the formation (17.08 Ma). The Pisco Formation is divided into three allomembers representing three transgressive cycles, P0, P1, and P2, from oldest to youngest. The vertebrate content of P0 is still scarcely known but clearly differs from that of the overlying P1, in which baleen-bearing whales are mainly represented by medium-sized cetotheriids; in contrast, in P2, balaenopterids dominate the assemblage. The chronostratigraphic framework was reconstruct with different methods. Sr isotope analyses on carbonates and phosphates suggest a Langhian – Serravallian age for the P0 allomember. Ar-Ar dating and diatom biostratigraphy indicate a Tortonian age for the P1 allomember (from 9.46 to 8.60 Ma), and a Tortonian – Messinian age for the P2 allomember (from 8.39 to 6.71 Ma). Tephra fingerprinting has been applied to build a high-resolution stratigraphy of P2 deposits and to correlate sediments exposed in different localities. The preservation of both fossil vertebrates and invertebrates is truly exceptional in the East Pisco Basin deposits. Using optical and scanning electron microscopy and cathodoluminescence, the taphonomy of invertebrates was studied. In the Chilcatay Formation, mollusk shells are mainly made by Ca-carbonates and show a quite good preservation. Oysters show, in some cases, a well preserved pristine prismatic layer that suggests a low degree of alteration, and cathodoluminescence reveals that several samples are characterized by a low and homogeneous luminescence. The latter specimens are those selected for Sr isotope analyses applied for chronostratigraphic studies. For taphonomic studies, the Chilcatay barnacle facies recognized in Ct1 can be related to a relatively shallow-water, high-energy environment. The Pisco Formation mollusks are commonly preserved only as gypsum casts or dolomite/gypsum internal molds. Sr isotopic ratios indicate an early diagenetic formation for dolomite and a pre-Miocene seawater-derived brine origin for gypsum. Regarding vertebrate taphonomy, in the Chilcatay Formation bones exhibit a good preservation, due to fluctuations of euxinic and oxic-dysoxic conditions at the seafloor, suggested by the size distribution of pyrite framboid relics. In the Pisco Formation, the calculation of the sedimentation rates suggests that the good preservation of the fossil remains is not due to the rapid burial, but is related to early establishment of anoxic processes that allow phosphatization, and not only to the formation of carbonate nodules.

This paper analyzes the policy of upgrading the teaching profession in relation to financing basic education, with a view to participation of the Union of Education Workers of Rio Grande do Norte - SINTE / RN and the state government in the implementation of Professional Base Salary the National Professional Teaching Public Basic Education - Law 11738/2008, the public state of Rio Grande do Norte. The participation of civil society, through the union movement presents itself as an important process of implementation of Professional Base Salary. The participation of SINTE / RN occurred since the fight to pass the plan, careers and Compensation (2006) until the implementation of the Base Salary (2009) highlighting the power relations established between the Union and State Government. To this end, there were actions such as public hearings and strikes by education professionals. In order to raise issues relevant to the issue of enhancement of teaching and participation of unions as a collective representation has been taken as a theoretical and methodological literature on the financing of basic education, enhancing teaching and participation as well as policy guidelines governing the career of teaching. Was used as a methodological procedure to document analysis and information gathering through semi-structured interviews. The results indicate the participation and the power relationship between the trade union movement and the state government in the implementation of the Base Salary. However, the current issues concerning the limitations of recovery of the teaching profession in order to implement the policy floor, not only merit of the state of Rio Grande do Norte, but the decisions that have been taken by the Supreme Court (STF) relating to the unconstitutionality of Action (ADI) filed by five governors. This fact greatly reduced the possibility of recovery of the teaching of the state, considering that the government was limited to decisions of the Supreme Court. Therefore, the enhancement of teaching remains a challenge for the union movement

Os resultados indicam a participa??o e a rela??o de poder entre o movimento sindical e o governo estadual na implementa??o do Piso Salarial. Por?m, as quest?es atuais referentes ?s limita??es da valoriza??o do magist?rio, tendo em vista, a pol?tica de implementa??o do Piso, n?o ? m?rito apenas da rede estadual do Rio Grande do Norte, e sim, das decis?es que vem sendo tomadas pelo Supremo Tribunal Federal (STF) referentes ? A??o Direta de inconstitucionalidade (ADI) impetrada pelos cinco governadores. Esse fato reduziu sobremaneira a possibilidade da valoriza??o do magist?rio da rede estadual, considerando que o governo limitou-se ?s decis?es do STF. Assim sendo, a valoriza??o do magist?rio continua sendo um desafio para o movimento sindical

Texte intégralRésumé :
This thesis presents a new template for multidisciplinary habitat mapping that combines the analyses of seafloor geomorphology, oceanographic proxies and modelling of associated biologic features. High resolution swath bathymetry of the Faial and western Pico shelves is used to present the first state-of-the-art geomorphologic assessment of submerged island shelves in the Azores. Solid seafloor structures are described in previously unreported detail together with associated volcanic, tectonic and erosion processes. The large sedimentary expanses identified in the area are also investigated and the large bedforms identified are discussed in view of new data on the local hydrodynamic conditions. Coarse-sediment zones of types hitherto unreported for volcanic island shelves are described using swath data and in situ imagery together with sub-bottom profiles and grainsize information. The hydrodynamic and geological processes producing these features are discussed. New oceanographic information extracted from satellite imagery is presented including yearly and seasonal sea surface temperature and chlorophyll-a concentration fields. These are used as proxies to understand the spatio-temporal variability of water temperature and primary productivity in the immediate island vicinity. The patterns observed are discussed, including onshore-offshore gradients and the prevalence of colder/more productive waters in the Faial-Pico passage and shelf areas in general. Furthermore, oceanographic proxies for swell exposure and tidal currents are derived from GIS analyses and shallow-water hydrographic modelling. Finally, environmental variables that potentially regulate the distribution of benthic organisms (seafloor nature, depth, slope, sea surface temperature, chlorophyll-a concentration, swell exposure and maximum tidal currents) are brought together and used to develop innovative statistical models of the distribution of six macroalgae taxa dominant in the infralittoral (articulated Corallinaceae, Codium elisabethae, Dictyota spp., Halopteris filicina, Padina pavonica and Zonaria tournefortii). Predictive distributions of these macroalgae are spatialized around Faial island using ordered logistic regression equations and raster fields of the explanatory variables found to be statistically significant. This new approach represents a potentially highly significant step forward in modelling benthic communities not only in the Azores but also in other oceanic island shelves where the management of benthic species and biotopes is critical to preserve ecosystem health.

Texte intégralRésumé :
Clastic packages studied in the southern East Pisco Basin represent the transgressive Late Eocene to earliest Oligocene Paracas Group, with questionable presence of the latest Oligocene to Early Miocene Chilcatay formation. Syndepositional faulting and rugged topography protected Late Eocene sediment from direct wave attack. Fluvial systems were poorly developed in this arid environment, where sediment gravity flows provided poorly sorted sediment to fan deltas in proximal and inner shelf areas. Shelf facies contain evidence of storm-dominated sand transport and variable rates of bioturbation and suspended sediment input. In conjunction with compositional increases in igneous derived sediment, the preservation of wave induced structures increased between Paleogene and Neogene time. Factors associated with these changes include higher rates of transgression and lower sediment supply during the Late Eocene, less protected depositional areas, arid climates, and a dramatic increase in the supply of sand-sized volcanic sediment in Neogene time.

Texte intégralRésumé :
Yumaque formation biosiliceous sediments resemble modern and Neogene sediments deposited under coastal upwelling conditions. High biogenic silica accumulation rates (up to 69 g$\cdot$cm$\sp{-2}\cdot$yr$\sp{-3}$), preservation of fine sedimentary features, and high original organic carbon, resulted from favorable basin geometries and upwelling of nutrient-rich water. Light biosiliceous-rich and dark detrital-rich alternations occur at scales ranging from millimeters to meters. Mm-scale laminae couplets are interpreted as varves. Spectral analysis of laminae thickness using a varve-calibrated time scale reveals significant variance at periods of 5-6 and 8 years, within the El Nino (ENSO) frequency band, and at 11 years, possibly linked to the 10-12 year solar cycle. Centimeter to meter-scale cyclicity representing between a few hundred to a few thousand years correlates to solar and geomagnetic phenomenon. The Yumaque formation and similar biosiliceous deposits along the eastern Pacific margin may be indicative of widespread late Eocene biosiliceous sedimentation around the Pacific.

Texte intégralRésumé :
The basins of the study area were filled with the following sequences: E$\sb0$ (lower? to middle Eocene); E1 E2 and E3 (fill middle Eocene half grabens); E-O (uppermost middle Eocene-Oligocene); M1, M2 and M3 (lower-upper Miocene); P (uppermost Miocene-Pliocene); and, Q (Quaternary). Four compressive events occurred during Paleocene?, middle Eocene?, upper-middle to late Miocene and middle Pliocene?; and two extensional episodes took place during middle Eocene and late Pliocene. Pre-Tertiary substratum was involved in all tectonic events. The Salaverry-Trujillo High which formed during the third compressive event and the Pliocene consists of a trench-parallel open flexure and a belt of middle Eocene to upper Miocene inverted wedges. The continuous uplifting of the Salaverry-Trujillo High produced a sustained shallowing of the sea floor at the slope break zone on the western side of the high and the incision of submarine canyons.

Texte intégralRésumé :
Neogene sediments rich in siliceous microfossils, phosphate, and organic carbon formed simultaneously in many basins around the Pacific. This work focuses on these (and similar older) sediments from two basins of western South America (East Pisco and Sechura Basins) and studies the effects of tectonism, climate, and oceanic circulation on their formation.
Transgressions inundated the East Pisco Basin during the late Eocene, late early Miocene, and late Miocene. Diatomaceous sediments formed during each transgression. Late Eocene diatomaceous sediments suggest that: upwelling off Peru dates from the late Eocene, a proto-Humboldt current existed during the Eocene, Antarctic cooling began before the latest Eocene, and the terminal Eocene event was the culmination of oceanic-climatic change.
The late Eocene diatomites differ from overlying late Miocene sediments. Eocene diatomites are restricted to the western (offshore) margin of the basin, are separated from paralic sediments by a mud blanket, and were deposited well below wave base. Upper Miocene-Pliocene diatomites occur throughout the basin, grade into paralic deposits, and were deposited, in part, above storm wave base.
The Sechura Basin experienced four transgressions between the Eocene and late Miocene. These transgressions formed four sedimentary sequences. Diatomaceous sediments are found in each sequence except the second (upper Oligocene-lower Miocene). In the third sequence (lower Zapallal Formation) diatomite-phosphorite became important between 14 and 8.1 Ma, and apparently reflects increased biogenic and decreased (?) terrigenous sedimentation rates. The increased biogenic accumulation rate reflects increased primary productivity or preservation. Sediments of the third sequence are separated from the fourth sequence by an angular unconformity (which correlates with subduction of the Nazca Ridge under the basin). Sediments of the fourth sequence differ from those of the third, and apparently record cooling and strengthened currents during the latest Miocene.

Texte intégralRésumé :
Chapter 25 introduced some basic generic principles applicable to many measurement and monitoring techniques. Chapter 43 introduces those principles not covered in Chapter 25 and discusses in detail the clinical applications and limitations of the many monitoring techniques available to the modern clinical anaesthetist. It starts with non-invasive blood pressure measurement, including clinical and automated techniques. This is followed by techniques of direct blood pressure measurement, noting that transducers and calibration have been discussed in Chapter 25. This is followed by electrocardiography. There then follows a section on the different methods of measuring cardiac output, including the pulmonary artery catheter, the application of ultrasound in echocardiography, pulse contour analysis (LiDCO™ and PiCCO™), and transthoracic electrical impedance. Pulse oximetry is then discussed in some detail. Depth of anaesthesia monitoring is then described, starting with the electroencephalogram and its application in BIS™ monitors, the use of evoked potentials, and entropy. There then follow sections on gas pressure measurement in cylinders and in breathing systems, followed by gas volume and flow measurement, including the rotameter, spirometry, and the pneumotachograph, and the measurement of lung dead space and functional residual capacity using body plethysmography and dilution techniques. The final section is on respiratory gas analysis, starting with light refractometry as the standard against which other techniques are compared, infrared spectroscopy, mass spectrometry, and Raman spectroscopy (the principles of these techniques having been introduced in Chapter 25), piezoelectric and paramagnetic analysers, polarography and fuel cells, and blood gas analysis.

Texte intégralRésumé :
The concept of dignity typically brings to mind an idea of moral status that supposedly belongs to all humans equally, and which serves as the basis of human rights. But this moralized meaning of dignity is historically very young. Until the mid-nineteenth century, dignity suggested an idea about merit: it connoted elevated social rank, of the sort that marked nobility or ecclesiastic preferment. What explains this radical change in meaning? And before this change, did anything like the moralized concept of dignity exist, that is, before it was named by the term “dignity”? If so, exactly how old is the moralized concept of dignity? In this volume, leading scholars across a range of disciplines attempt to answer these questions by clarifying the presently murky history of “dignity,” from classical Greek thought through the Middle Ages and Enlightenment to the present day. In the process, four platitudes about the history of human dignity are undermined: (1) the Roman notion of dignitas is not the ancient starting point of our modern moralized notion; (2) neither the medieval Christian doctrine of imago Dei nor the renaissance speech of Pico della Mirandola, Oration on the Dignity of Man, was a genuine locus classicus of dignity discussion; (3) Immanuel Kant is not the early modern proprietor of the concept; (4) the universalization of the concept of dignity in the postmodern world (ca. 1800–present) is not the result of its constitutional indoctrination by the “wise forefathers” of liberal states like America or France.

Texte intégralRésumé :
ABSTRACT Sequence stratigraphy has proven to be an invaluable tool for the analysis of coarse-clastic depositional systems and the integration of observations across scales from reflection seismic to scanning electron microscope. Applications to mudstone-dominated depositional sequences have been more limited, despite the fact that mudstones make up more than 60% of the global sedimentary volume and generally provide the most complete record of sedimentation in a basin. During the late 1970s and through the 1980s, Bob Garrison and his students at the University of California–Santa Cruz conducted numerous studies that revealed the basic sedimentary and stratigraphic framework of the Monterey Formation in California, advancing our understanding of the sedimentary processes at work in these deep-margin basins. We expanded on that framework using direct observations from outcrops and cores that have been integrated with other subsurface data, as well as a wide variety of information derived from paleontologic, chronostratigraphic, geochemical, and compositional analyses to illustrate a sequence-stratigraphic approach to interpreting fine-grained rocks and their associated depositional systems in these settings. These were some of the earliest investigations of mudstone sequence stratigraphy focused on slope and basinal environments. In this study, observations from outcrops in the Pismo Basin, California, provided the basis for developing a detailed sequence-stratigraphic framework for the Monterey Formation, expanding on the broad-scale characterization of Garrison and his colleagues. These outcrops represent deposition during different phases of basin evolution and in different borderland-type basin settings (slope and basin depocenters). Comparison of coeval strata from different depositional settings and locations documented variation at both the sequence and parasequence scale. Variation of parasequence character, in particular, provided a valuable tool for enhanced understanding of deposition and diagenesis in these margin basins. Extrapolation to the subsurface using gamma-ray logs greatly enhanced basinwide application compared to limited, partial-stratigraphic-section outcrops, and it facilitated the lateral characterization of mudstone depositional sequences. These elements served as the building blocks for improved models of deposition in margin-basin settings.

Texte intégralRésumé :
The time-optimal control problem (TOCP) has faced new practical challenges, such as those from the deployment of agile autonomous vehicles in diverse uncertain operating conditions without accurate system calibration. In this study to meet a need to generate feasible speed profiles in the face of uncertainty, we exploit and implement probabilistic inference for learning control (PILCO), an existing sample-efficient model-based reinforcement learning (MBRL) framework for policy search, to a case study of TOCP for a vehicle that was modeled as a constant input-constrained double integrator with uncertain inertia subject to uncertain viscous friction. Our approach integrates learning, planning, and control to construct a generalizable approach that requires minimal assumptions (especially regarding external disturbances and the parametric dynamics model of the system) for solving TOCP approximately as the perturbed solutions close to time-optimality. Within PILCO, a Gaussian Radial basis functions is implemented to generate control-constrained rest-to-rest near time-optimal vehicle motion on a linear track from scratch with data-efficiency in a direct way. We briefly introduce the importance of the applications of PILCO and discuss the learning results that PILCO would actually converge to the analytical solution in this TOCP. Furthermore, we execute a simulation and a sim2real experiment to validate the suitability of PILCO for TOCP by comparing with the analytical solution.

Texte intégralRésumé :
This chapter presents three electronics-based projects at increasing levels of sophistication. Two of the projects use the PIC microcontroller-based MicroMite chip. One uses the new Raspberry Pi PICO microcontroller board. All three deliver base level units that monitor atmospheric pressure (Projects 1 and 2) and ambient light levels (Project 3). All three communicate bidirectionally with an app on an Android mobile phone via the popular and well supported Bluetooth protocols. In the final technical section of the chapter, the content of those Bluetooth communications are ‘pushed' onto a local IoT intranet design. The chapter closes with a brief summary of the STEAM initiatives in Australia plus a brief discussion of the importance of electronics in contemporary life which arguably justifies their inclusion in STEAM curricula content.

Texte intégralRésumé :
The Jamapa River basin is located in the central region of the State of Veracruz, it is born in the Pico de Orizaba and connects with the Veracruz Reef System in the Gulf of Mexico, both protected natural areas. The lower part of the basin has the contribution of two important effluents, Arroyo Moreno, which is a protected natural area, strongly impacted due to municipal discharges from the metropolitan cities Veracruz-Boca del Río-Medellín. And the Estero, which is part of a complex aquatic system that discharges its waters from the Lagunar Mandinga system to the Gulf of Mexico. Currently, there is a diversity of chemical and biological compounds that the basin receives from different sources of freshwater pollution, such as industrial waste, sewage, agricultural and urban runoff, and the accumulation of sediments. The climatic seasons are the determining factors in the composition of its sediments, due to the force exerted on the bottom of the river by the increase in rainfall, the force of the winds mainly in the north wind season, where the greatest quantity of polluting materials.

Texte intégralRésumé :
The subject of the paper is the relationship between the duties of physicians and other medical professionals towards the dying patient (as a provider of medical services) and the patient's right to personal choice and preservation of his own right to self-determination in relation to body and life, which is a special subjective civil right. The author discusses the legal-medical (but also ethical) issue of the patient's ability to freely decide not to agree to a medical measure of artificial prolongation of life or suspension of already started measures. The issue is examining the limits of the so-called permissibility of “passive euthanasia”, which is indirectly recognized in domestic law by the Law on Patients' Rights and the legal basis for its application in one particular modality, the so-called "Patient letter" (living will) which is an established legal instrument in some foreign legislation and practice. Analyzing the experience of some foreign countries, the author supports the introduction of such an institute - as a kind of anticipated directives in domestic law, referring to the patient's constitutional right to self-determination, which embodies the supreme good, even more valuable than (unwanted) life. Such a solution is in line with the principle of human will autonomy, freedom to dispose of life as a personal good, and potentially a reflection of the so-called "the right to die", which is the reverse of the right to life

Texte intégralRésumé :
For many of those working in maritime industries, it is very common to be exposed to harsh environments, such as cold water, on a regular basis. We conducted a scoping review on peer reviewed, published papers to summarize the literature on the topic cold water exposure and non-freezing cold water injuries in the maritime industries. First, industry experts were consulted, then a PICO model was created to define the search terms for the review. The initial search produced 690 abstract. Of these abstracts, 14 were considered to be relevant to the review. The scoping review findings illustrated the lack of research that currently exists in relation to cold water exposure in the maritime industries. Within the available, albeit limited, literature, evidence suggests that there are several cold-water injuries that occur in the maritime industries. These include occupational dermatosis, Raynaud’s phenomena, finger blanching, and hand numbness. Performance decrements were also reported. The current gaps include a lack of documentation of minor and non-fatal injuries, the amount of exposure, and training protocols. There is a need to improve cold-water training regulations for those working in the maritime industries and for proper injury documentation, both of which can significantly benefit safety.

Texte intégralRésumé :
Abstract Large-scale deployment of carbon capture and storage (CCS) is a key decarbonization approach to achieve drastic reductions in greenhouse gas emission levels. The United States Department of Energy's National Energy Technology Laboratory, through the Carbon Storage Assurance Facility Enterprise Initiative projects, defines a commercial-scale CO2 saline storage project as one in which at least 50 million tonnes of CO2 are injected over the course of 20 to 30 years. Large-scale decarbonization through CCS may likely involve many commercial-scale CO2 storage projects located in close proximity. Nearby injection operations may result in CO2 plume commingling and create pressure buildup over time, which could cause pressure interference and may require preventative strategies to avoid exceedance of fracture pressure threshold. This study employs numerical modeling to analyze the evolution of the extent of CO2 and pressure plumes in which the commercial-scale CO2 storage projects inject simultaneously into a common storage formation from multiple projects located in proximity. Injection operations target an extensive saline formation with formation top of 1 km below ground surface, thickness of 200 m, horizontal and vertical permeabilities of 50 and 15 mD, porosity of 10%, and all external boundaries closed to fluid flow (i.e., top, bottom and all sides). The injection occurs at 1 million tonnes/year per well for 30 years, followed by a 50-year post-injection period (PISC). The effect of well spacing and resulting pressure buildup and CO2 plume migration is explicitly evaluated. For the circumstances modeled, our analysis indicates that the radius of the CO2 plume extends 2-4 km from the CO2 injection well(s). Under the multi-project injections, CO2 plume commingling does not occur during injection; however, during PISC and pressure equilibration, CO2 plumes commingle under certain well spacings. However, the radius of the pressure-buildup plume is in the range of tens or a few hundreds of kilometers, depending on the amount of pressure increase used to define the plume edge. These findings indicate that a degree of pressure interference can occur between storage projects located near each other, particularly during the early stages of the project. Additionally, our analysis of pressure interference shows that required well spacing needed to avoid approaching or exceeding fracture pressure thresholds can be extensive for formations with low fracture gradients (i.e., in the range of 80–125 km for formations with a pressure gradient of 0.6 psi/ft), but significantly smaller for formations with higher fracture gradients (i.e., 5 km for 0.8 psi/ft). Given the potential pressure interference which may occur from multiple projects, this analysis shows the importance of coordination among storage operators and regulatory stakeholders. Because this study analyzes a very specific geologic situation, well configuration, CO2 injection rate and boundary conditions, this exploratory study bears further investigations across other geologic situations.

Texte intégralRésumé :
Coupling thermo-fluid-structure field are analyzed by use of CFD and FEM. A direct simulation of 3D liquid metal flow in the Dual Coolant Lead Lithium (DCLL) blanket is conducted to study the MHD effects and heat transfer influenced by different material properties of FCI (Flow Channel Insert). A consistent and conservative scheme and PISO method on an unstructured collocated mesh are employed to solve the incompressible Navier-Stokes equations with the Lorentz force included based on an electrical Potential formula. The finite element method is employed to study mechanical behavior of FCI. The velocity distribution, MHD pressure drop, current stream lines and temperature distribution of blanket, thermal deformations and thermal stresses in FCI under external magnetic field are investigated. The effects of thickness and electric conductivity of a silicon carbide FCI on temperature field in fluid-structure coupling field, thermal stresses and deformation are analyzed. This work is the theoretical basis of optimizing blanket.

Texte intégralRésumé :
A self-field MPD thruster in its most basic form consists in a central cathode surrounded by a concentric anode. With this coaxial geometric shape is very difficult to use experimental techniques to visualize the plasma flow parameters. In the following paper a previously proposed numerical method for the ideal magnetohydrodynamics (MHD) equations is extended to deal with resistive MHD viscous flow. The numerical method is based on the well known PISO algorithm and makes use of the AUSM-MHD scheme for flux calculation. For validation three test cases will be addressed. We start with a resistive MHD problem, namely the Shercliff test case. The second and third test cases are standard 2D ideal MHD problems, these will be used to validate our method for complex interaction of MHD shocks. We will close this paper with some preliminary results for a quasi-bi-dimensional self-field magnetoplasmadynamic (MPD) thruster, where the effects of cathode length in the performance of the nozzle are analysed.

Texte intégralRésumé :
Electrowetting-on-dielectric (EWOD) is a highly efficient technology to perform biological and medical analyses through the manipulation of pico- to nano-liter droplets on digital microfluidic systems (DMS). Droplet splitting is one of the basic fluidic operations that play a vital role in microscale mixing and concentration control. This paper presents the results of numerical investigation of unequal droplet splitting. In order to gain insight into the mechanism of droplet splitting, a three-electrode splitting system is simulated in FLOW-3D® for given geometry and material properties. When unequal voltages are applied to the adjacent electrodes on both sides of a droplet the distribution of electric field exerts spatially varying stress causing the deformation of the interface. The resulting unequal fluid flow rates towards the activated electrodes are determined by the coupled electro-hydrodynamics. The results of multiple simulation runs in terms of liquid flow rates with different ratios of the applied voltage will be very useful in developing the open-loop model of droplet splitting that can be later adopted to design a controller for unequal splitting in DMS.

Background: Apathy is a multidimensional syndrome that impairs motivation and mechanisms of behavioural regulation. As apathy is almost ubiquitous in neurodegenerative disorders, understanding the neural basis is required to expand knowledge and ameliorate our instruments. Objective: Verify the feasibility, safety, and adherence of a remote physical and cognitive exercise protocol for elders; and to compare two different protocols and its effects on strength, cognitive functions and well-being. Methods: Use of the PICO strategy, conducted on September 17, on PubMed using “Alzheimer disease” and “diabetes mellitus” as descriptors, identifying 14 articles, selecting 4 after screening. Inclusion criteria: clinical and randomized controlled trials with diabetic and Alzheimer patients, published on the last 5 years. Exclusion criteria: articles focused on medications. Results: Overall adherence to the proposed sessions was 82,36% (sd16,8) in IG and 76,5% (sd24,04) in CG. There were no serious adverse events or drop-outs during the study. There was an improvement in strength and verbal fluency for IG and GDS for both groups (p ≤ 0,05). Conclusion: Both protocols seem a feasible program, reaching an acceptable level of adherence and safety. The technology used can represent a sustainable path for large scale use to promote aging active in developing countries.

Texte intégralRésumé :
Abstract The Camisea Pipelines Transportation System (STD) owned by Transportadora de Gas del Peru (TGP) is operated and maintained by Compania Operadora de Gas del Amazonas (COGA). The system consists of two pipelines: a 730-kilometer long Natural Gas (NG) pipeline, which runs from the Upstream facilities in the Malvinas to the Receptor Station in Lurin (south of Lima), which has a loop in the area of Coast of 135 km in length and the Natural Gas Liquids pipeline (NGL) of 557 kilometers, which transports the condensed liquids from Malvinas to Pisco, on the coast of Peru. In the first 210 km, it crosses a complicated zone of the Peruvian Amazon, between the kilometric poste (KP) 210 and KP 420, the sector of the mountain range is defined and between the KP 420 and KP 730, the coastal sector is located. Due to the influence area and the project magnitude, solutions for many problems frequently require access to various types of information that can only be geographically related or by their spatial distribution. In this sense the Geographic Information Systems (GIS), provides the necessary tools to store and manage information using these references, thus allowing to analyze patterns of behavior, relationships and trends in information, all with the interest of contributing to the taking of better decisions. Likewise, given the complicated geography on which the project is developed, as well as the populations dynamic, the threats of geohazards and damages by third parties respectively, require evaluations and field data collection on a permanent basis, this also because it is about threats that are independent of time and that represent the highest percentage of failures for the South American pipelines. In this sense, data collection using GIS technology allows users, through the use of previously established forms, to capture field information, as well as the corresponding photographic record. Also, during the data collection, users have at their disposal on their mobile devices relevant information that allows a more objective spatial and temporal analysis of a specific place. This information is synchronized with the GIS database of the organization and used in the evaluation of risks to the integrity of the pipelines. This article describes the methodology for field data collection, using GIS technology, as well as the process of validation and publication of the data in the Geodatabase of the company and the benefits associated with having updated and available information to guarantee the best decision making.

Texte intégralRésumé :
ABSTRACT Background: Acute malnutrition is the highest cause of death among children under five. This is because children are a group that is vulnerable to health problems, one of which is infection. In this phase there is a very rapid growth and development in children. This problem occurs in part in low- and middle-income countries. This study aimed to review the effect of supplementary food therapy for recovery among malnourished children aged 0-59 months. Subjects and Methods: This was a scoping review using the Arksey and O’Malley framework. The framework used to identify relevant studies is Population, Intervention, Comparison, and Outcome (PICO), with a search strategy using 5 databases, namely PubMed, Science Direct, Proquest, Wiley, and Google Scholar which match the inclusion and exclusion criteria. Results: Supplementary food therapy for recovery of malnourished children 0-59 months could be done with inpatient and outpatient care using Modified Dried Skilled Milk and Coconut Oil (Modisco), Ready to use Therapeutic Food (RUTF), Soy Maize Sorghum RUTF (SMS RUTF), F 75, and F 100. The most widely used recovery supplementary food therapies are Modisco, RUTF, SMS RUTF, F75 and F100. RUTF in Indonesia has not been widely used for the therapy of malnourished children, while for F75 and F100 it has been used as a treatment but not maximally because it tastes bad so it is not liked by children. Conclusion: Several studies have examined the effectiveness of these supplementary foods, apart from being used in the hospital, they can also be given on an outpatient basis with the supervision of related health workers.
