This map serves as a basis for modeling the shape of basins and for determining the location and geometry of faults in the area. Local spatial variations in the Earth's gravity field after removing variations caused by instrument drift, earth-tides, latitude, elevation, terrain, and deep crustal structure , as expressed by the isostatic anomaly, reflect the distribution of densities in the mid- to upper crust, which in turn can be related to rock type.

Steep gradients in the isostatic gravity field often indicate lithologic or structural boundaries. Gravity highs reflect the Mesozoic granitic and Franciscan Complex basement rocks that comprise both the northwest-trending Santa Lucia and Gabilan Ranges, whereas gravity lows in Salinas Valley and the offshore basins reflect the thick accumulations of low-density alluvial and marine sediment.

Within the map area, isostatic residual gravity values range from approximately mGal offshore in the northern part of the Sur basin to approximately 22 mGal in the Santa Lucia Range. A solid waste management survey in Davao del Sur school and household waste management survey. Environmental degradation has become a very alarming issue at present.

Human activities have been the primary cause of this unfortunate event which has resulted to other complications such as health problems. The resources are limited and people solely depend on it for living. Thus, the necessity to address these concerns arises. Various solid waste management programs have been established however the people's commitment has continued to challenge the local authorities as well as the cooperating agencies. This study was conducted in order to assess the awareness, practice and attitude towards the existing solid waste management programs of the selected students in Davao del Sur.

It also aims to measure the effectiveness and current status of these implemented programs. The study used survey method. One hundred sixty eight of students were surveyed using a validated, self-administered instrument. The study revealed that majority of the students is well aware of the existing solid waste management programs, practice them and is willing to learn more about the issue. Others, on the other hand, do the opposite. It is of great importance that all citizens must commit in the implementation of environmental programs so as to be more effective. The pond is particularly attractive for birds because of its variety of food items.

A total 25, records of 69 species were done, among them the first report of Chlidonias niger and Phalaropus tricolor for the region. Species richness and abundance were determined for the migrant component, mostly Anatidae 16 species and The greater number of species and individuals was in C the deepest and more heterogeneous section of the pond.

The artificial pond presented an atypical and distinct ornithological composition because it is located in an arid region, and acts as a resting site for migrant birds. The site included species that usually live in freshwater and coastal areas, a characteristic reflected in their high richness.

It contributes noticeably to the local avian biodiversity. This major rehabilitation of a year-old, MW, oil-fired boiler was accompanied by the upgrading of the low-pressure turbine with new rotors. The boiler rehabilitation included the replacement of all waterwall floor panels from just below the burner windbox, down to the lower drum.

Cicatrice Acné Chirurgie Esthétique Yahoo Fnac

Temporary support was provided for the lower drum and its structural system during the panel replacement. The superheater and reheater desuperheater liners were also replaced. In addition, all major components of both the firing system and the air preheaters were replaced. The gas recirculation fan was rehabilitated, and its discharge duct was replaced. The aim of the study was to establish an inventory of staff in the hospital who smoked to allow better identification of people at risk and thus develop targeted preventive strategies, which we hoped would be more effective.

This survey was conducted at the Rochefort- sur -Mer Hospital in March The sociodemographic characteristics of the population responding and differences in characteristics between smokers and non-smokers were examined. The level of dependence of smokers and patterns of smoking in the workplace were also evaluated. The hospital staff is still weakly dependent on tobacco.

The attitude to smoking was strongly linked to socioeconomic group and the domestic staff and health care assistants were most likely to smoke and were also the most dependent. Finally, the hospital has itself become a smoke free environment without tobacco. It is essential to promote measures to prevent smoking among hospital staff taking into account its specific features high proportion of women.

Targeted actions should in particular be conducted amongst the groups of workers who are the most affected. Uranium-series dating of coral samples from raised marine terrace deposits between 1. The stratigraphy and ages of marine units near the El Coyote Arroyo indicate the presence of two high stands of the sea during the last interglacial or oxygen isotope substage 5e at about ka and ka.

Accepting 5 m for the sea level during the last interglacial transgression, we calculate average uplift rates for the marine terraces of about??? These slow rates of uplift indicate a relative stability of the La Paz peninsula area for the past years. In contrast, areas of Baja California affected by major faultf experienced higher rates of uplift. The chimeric construct was expressed in Xenopus oocytes and characterized using the patch-clamp technique.

We found that activation by MgADP and synthetic openers was greatly attenuated although apparent affinities were unchanged. Further chimeragenetic and mutagenetic studies showed that mutation of three residues, E, I and L rat numbering , was sufficient to confer this defective phenotype. The same mutations had no effects on channel block by the sulphonylurea glibenclamide or by ATP, suggesting a role for these residues in activatory — but not inhibitory — transduction processes.

Manipulation with SUR 2A levels has been suggested to be a promising therapeutic strategy against ischaemic heart diseases and other diseases where increased heart resistance to stress is beneficial. Some years ago, it has been reported that high-altitude residents have lower mortality rates for ischaemic heart disease. Modelisation de la diffusion sur les surfaces metalliques: De l'adatome aux processus de croissance. Cette these est consacree a l'etude des processus de diffusion en surface dans le but ultime de comprendre, et de modeliser, la croissance d'une couche mince.

L'importance de bien mai triser la croissance est primordiale compte tenu de son role dans la miniaturisation des circuits electroniques. Nous etudions ici les surface des metaux nobles et de ceux de la fin de la serie de transition. Dans un premier temps, nous nous interessons a la diffusion d'un simple adatome sur une surface metallique. Nous avons, entre autres, mis en evidence l'apparition d'une correlation entre evenements successifs lorsque la temperature est comparable a la barriere de diffusion, i.

Nous proposons un modele phenomenologique simple qui reproduit bien les resultats des simulations. Ces calculs nous ont aussi permis de montrer que la diffusion obeit a la loi de Meyer-Neldel. Cette loi stipule que, pour un processus active, le prefacteur augmente exponentiellement avec la barriere. En plus, ce travail permet de clarifier l'origine physique de cette loi. En comparant les resultats dynamiques aux resultats statiques, on se rend compte que la barriere extraite des calculs dynamiques est essentiellement la meme que celle obtenue par une approche statique, beaucoup plus simple.

On peut donc obtenir cette barriere a l'aide de methodes plus precises, i. C'est ce que nous avons fait pour plusieurs systemes metalliques. Nos resultats avec cette derniere approche se comparent tres bien aux resultats experimentaux. Nous nous sommes attardes plus longuement a la surface du platine. Cette surface regorge de particularites interessantes, comme la forme d'equilibre non-hexagonale des i lots et deux sites d'adsorption differents pour l'adatome.

De plus, des calculs ab initio precedents n'ont pas reussi a confirmer la. L'effet des deformations plastiques severes sur les proprietes d'hydruration du magnesium. Le travail de recherche effectue durant mon projet de maitrise en physique a l'Universite du Quebec a Trois-Rivieres dans les laboratoires de l'Institut de Recherche sur l'Hydrogene etait de comparer l'effet du laminage a froid de la poudre de MgH2 avec celui du broyage mecanique. Nous avons etudie cette nouvelle technique en utilisant un laminoir vertical concu specialement pour laminer de la poudre.

Nous avons lamine la poudre de MgH2 5, 25, 50 et fois. La comparaison de la morphologie de la poudre de MgH 2 telle que recu du manufacturier et broye mecaniquement pendant 30 minutes avec celle de la poudre laminee ete faite a l'aide d'un microscope electronique a balayage. Nous avons par la suite mesure les proprietes de sorption d'hydrogene grace un appareil PCT de type Sievert.

Nous avons aussi determine la structure cristalline par diffraction de rayons X. Nous avons aussi utilise les courbes de cinetiques d'absorption et de desorption d'hydrogene pour calculer l'etape limitative dans les reactions de sorption des echantillons lamines. Comme cinq laminages se font en environ 10 secondes, on voit que le laminage a froid est une technique plus interessante industriellement que le broyage mecanique a cause de l'important gain en temps et en energie.

This study focuses on the cartography and stratigraphy of area in order to understand the evolution of the volcanic system. The stratigraphy from base to top consists of a series of shallow marine sediments fossiliferous sandstones covered by a thick sequence of ignimbrites and pyroclastic flows interbedded with volcaniclastic deposits Gloria and El Infierno Formations. On top of these deposits is El Aguajito caldera, it consists of a 2 m thick pumice fallout followed by an ignimbrite with three transitional lithofacies: On top rests a 15 m-thick light-purple ignimbrite slightly welded with fiammes and a sequence of pumiceous pyroclastic flows and fallouts.

This cartography allowed to present a preliminary new geological map with four stratigraphic units recognized so far, that were emplaced under subaerial conditions beginning with a Plinian column followed by the emplacement of El Aguajito ignimbrite with its subsequent caldera collapse and finally the extrusion of resurgent domes. Availability of safe drinking-water: Nabua, Camarines Sur , Philippines, In May , there were increasing diarrhoea cases and deaths reported from Nabua, Camarines Sur to the Philippines event-based surveillance system. An investigation was conducted to identify risk factors and determine transmission dynamics.

A suspected case was defined as a resident of Nabua with at least three episodes of watery diarrhoea per day from 16 March to 22 June A confirmed case was defined as a suspected case positive for Vibrio cholerae.

Cicatrice En T Poitrine

An environmental investigation was conducted and rectal swabs and water samples sent to the national reference laboratory for bacterial isolation. Data were analysed using Epi Info. Water samples were positive for faecal coliforms and Aeromonas caviae. In this cholera outbreak, drinking-water from unchlorinated wells was a significant risk factor. Future cholera control efforts should include not just improving water and sanitation systems but also intensified behaviour change campaigns.

Alkali burn injury is a true ocular emergency of the conjunctiva and cornea that requires immediate precision. Lack of an immediate therapy can lead to a substantial damage in the ocular surface and anterior segment further causing visual impairment and disfigurement. We explored the regenerative capability of dominant negative survivin protein Sur R9-C84A and histone deacetylase inhibitor trichostatin-A TSA in vivo, in a rat alkali burn model.

A topical insult in rat eyes with NaOH led to degradation of the conjunctival and corneal epithelium. The integrity of the conjunctival and corneal tissue was increased by TSA and Sur R9-C84A by improving the clathrin and claudin expressions. Protein expressions of fibronectin and alpha-integrin 5 were found to increase promoting corneal integrity. Our results confirmed that a combination of TSA with Sur R9-C8A worked in synergy and showed a promising healing and anti-inflammatory effect in a very short time against alkali burn.

Therefore, a combination of TSA and Sur R9-C84A can fulfill the need for an immediate response to wound healing in alkali burnt cornea. Effet de la teneur en carbone sur la resistance du CA6NM a la propagation des fissures de fatigue. L'amelioration des performances des roues de turbines hydrauliques a fait l'objet de plusieurs etudes. Dans ce memoire, on s'est interesse a l'effet de la teneur en carbone du materiau de base de type CA6NM des aubes de turbines sur la microstructure et les proprietes mecaniques en general et en particulier sur le comportement en fatigue propagation.

De maniere a bien atteindre cet objectif, on a choisi trois differentes nuances d'acier a faible 0. De meme, le 0. Apres avoir homogeneise la GPA, on a entame le revenu. Le carbone a une influence sur la microstructure revenue notamment la quantite d'austenite de reversion ainsi que sur sa stabilite thermique et mecanique. Pour mettre en evidence l'effet de la teneur en carbone, on a trouve raisonnable d'isoler les effets relies a la temperature de revenu, en particulier la formation d'austenite de reversion. En effet, on a choisi deux temperatures de revenu.

A la lumiere de ces deux microstructures, nous pouvons etablir une relation entre les proprietes mecaniques du CA6NM et la teneur en carbone, ainsi qu'entre les effets de la presence ou non d'austenite de reversion sur les. Here, we examined the chronic effects of two cannabinoid receptor-1 CB1 inverse agonists, rimonabant and ibipinabant, in hyperinsulinemic Zucker rats to determine their chronic effects on insulinemia. To elucidate the mechanism of insulin lowering, acute in vivo and in vitro studies were then performed.

Surprisingly, chronic treatment was not required for insulin lowering. Followup studies implied that these effects were inconsistent with a CB1-mediated mechanism. Our findings indicate that some CB1 ligands may directly bind and allosterically regulate Kir6. This mechanism appears to be compatible with and may contribute to their acute and chronic effects on GSIS and insulinemia. A Propos d'une Observation. The archaeology of the Pericue Indians inhabiting the Cape region of Baja California has long been an area of interest.

The dolichocranic traits exhibited by this population have lead to suggestions that these people were a relic population of an early coastal migration into North America. The antiquity of directly dated Pericue human remains only reaches 3, B. Increasing tourist development within this region threatens many archaeological sites particularly coastal shell middens and rock shelters.

Current rescue excavations are yielding important information regarding many aspects of the culture of the Pericue Indians. Initial results highlight a complicated and diverse diet including marine and terrestrial resources, most likely exploited seasonally. Similarities between the diet of the Pericue and other nearby coastal Indian groups are clear and will be discussed. Pericue Indian material culture, combined with the exploitation of marine mammals and the construction of enormous shell mounds display parallels with other central and North American groups.

The exploitation of marine mammals and the associated stone tools display striking similarities to the Chumash people of the Channel Islands of Coastal Southern California. Some of these cultural similarities will be highlighted in this presentation. Current genetic work is attempting to discover the nature of the similarities between the Chumash and Pericue groups as some cultural elements of each group have parallels with the other. Geochemistry of a Tertiary sedimentary phosphate deposit: Baja California Sur , Mexico. A detrital and a marine component were determined from major oxides.

The detrital component consists of an unaltered volcanic-ash fraction and a terrigenous clay-silt fraction. The marine component, which accumulated initially as biogenic and hydrogenous material, is now present as opal-A, opal-CT, CaCO3, organic matter, and an authigenic phosphate fraction, mostly pelletal and composed of the carbonate-fluorapatite mineral francolite.

The minor elements have been partitioned into these components by assuming a constant composition for the two detrital fractions. The composition of the marine component of minor elements can then be interpreted by assuming that the stoichiometry of the original accumulating organic matter was equal to that of modern plankton. The Cu and Cd contents in the marine component of all rocks require that the seawater-derived fractions of these two metals were supplied to the seafloor solely by organic matter.

Enrichments of Cr and V at both sites required an additional marine input. On the basis of their geochemistry in the modern ocean, Cr and V could have precipitated, or been adsorbed, onto settling particles from an O2 minimum zone in which the O2 content was low enough to promote denitrification rather than oxygen respiration. An enrichment of the REE, now within the apatite fraction, resulted from their adsorption onto particulates also in the O2 minimum zone and to the dissolution and alteration of biogenic phases predominantly silica within the sediment.

Co and Fe2O3 show no enrichment above a detrital contribution. Challenges and opportunities for implementing sustainable energy strategies in coastal communities of Baja California Sur , Mexico. This dissertation explores the potential of renewable energy and efficiency strategies to solve the energy challenges faced by the people living in the biosphere reserve of El Vizcaino, which is located in the North Pacific region of the Mexican state of Baja California Sur.

This research setting provides a practical analytical milieu to understand better the multiple problems faced by practitioners and agencies trying to implement sustainable energy solutions in Mexico. The thesis starts with a literature review chapter two that examines accumulated international experience regarding the development of renewable energy projects as a prelude to identifying the most salient implementation barriers impeding this type of initiatives. Two particularly salient findings from the literature review include the importance of considering gender issues in energy analysis and the value of using participatory research methods.

These findings informed fieldwork design and the analytical framework of the dissertation. Chapter three surveys electricity generation as well as residential and commercial electricity use in nine coastal communities located in El Vizcaino. Chapter three summarizes the fieldwork methodology used, which relies on a mix of qualitative and quantitative research methods that aim at enabling a gender-disaggregated analysis to describe more accurately local energy uses, needs, and barriers.

Chapter four describes the current plans of the state government, which are focused in expanding one of the state's diesel-powered electricity grids to El Vizcaino. The Chapter also examines the potential for replacing diesel generators with a combination of renewable energy systems and efficiency measures in the coastal communities sampled. Chapter five analyzes strategies to enable the implementation of sustainable energy approaches in El Vizcaino.

Chapter five highlights several international examples that could be useful to inform organizational changes at the federal. Modelling impacts of offshore wind farms on trophic web: The French government is planning the construction of three offshore wind farms in Normandy. These offshore wind farms will integrate into an ecosystem already subject to a growing number of anthropogenic disturbances such as transportation, fishing, sediment deposit, and sediment extraction. The possible effects of this cumulative stressors on ecosystem functioning are still unknown, but they could impact their resilience, making them susceptible to changes from one stable state to another.

Understanding the behaviour of these marine coastal complex systems is essential in order to anticipate potential state changes, and to implement conservation actions in a sustainable manner. Currently, there are no global and integrated studies on the effects of construction and exploitation of offshore wind farms. Moreover, approaches are generally focused on the conservation of some species or groups of species. Here, we develop a holistic and integrated view of ecosystem impacts through the use of trophic webs modelling tools.

Trophic models describe the interaction between biological compartments at different trophic levels and are based on the quantification of flow of energy and matter in ecosystems. They allow the application of numerical methods for the characterization of emergent properties of the ecosystem, also called Ecological Network Analysis ENA.

These indices have been proposed as ecosystem health indicators as they have been demonstrated to be sensitive to different impacts on marine ecosystems. We present here in detail the strategy for analysing the potential environmental impacts of the construction of the Courseulles- sur -Mer offshore wind farm Bay of Seine such as the reef effect through the use of the Ecopath with Ecosim software. Results will contribute to a better knowledge of the impacts of the offshore wind farms on ecosystems. They also allow to. Methodologie de conception numerique d'un ventilateur helico-centrifuge basee sur l'emploi du calcul meridien.

We have demonstrated recently that the tumor-to-blood standard uptake ratio SUR is superior to tumor standardized uptake value SUV as a surrogate of the metabolic uptake rate K m of fluorodeoxyglucose FDG , overcoming several of the known shortcomings of the SUV approach: However, due to the perfectly standardized uptake period used for SUR determination and the comparatively short uptake period, these results are not automatically valid and applicable for clinical whole-body examinations in which the uptake periods T are distinctly longer and can vary considerably.

Therefore, the aim of this work was to investigate the correlation between SUR derived from clinical static whole-body scans and K m-surrogate derived from dual time point DTP measurements. In the PET images, the primary tumor was delineated with an adaptive threshold method.

Mesure et retroaction sur un qubit multi-niveaux en electrodynamique quantique en circuit non lineair. L'electrodynamique quantique en circuit est une architecture prometteuse pour le calcul quantique ainsi que pour etudier l'optique quantique. Dans cette architecture, on couple un ou plusieurs qubits supraconducteurs jouant le role d'atomes a un ou plusieurs resonateurs jouant le role de cavites optiques.

Dans cette these, j'etudie l'interaction entre un seul qubit supraconducteur et un seul resonateur, en permettant cependant au qubit d'avoir plus de deux niveaux et au resonateur d'avoir une non-linearite Kerr. Je m'interesse particulierement a la lecture de l'etat du qubit et a son amelioration, a la retroaction du processus de mesure sur le qubit de meme qu'a l'etude des proprietes quantiques du resonateur a l'aide du qubit.

J'utilise pour ce faire un modele analytique reduit que je developpe a partir de la description complete du systeme en utilisant principalement des transfprmations unitaires et une elimination adiabatique. J'utilise aussi une librairie de calcul numerique maison permettant de simuler efficacement l'evolution du systeme complet. Je compare les predictions du modele analytique reduit et les resultats de simulations numeriques a des resultats experimentaux obtenus par l'equipe de quantronique du CEASaclay.

Ces resultats sont ceux d'une spectroscopie d'un qubit supraconducteur couple a un resonateur non lineaire excite. Dans un regime de faible puissance de spectroscopie le modele reduit predit correctement la position et la largeur de la raie. La position de la raie subit les decalages de Lamb et de Stark, et sa largeur est dominee par un dephasage induit par le processus de mesure.

Je montre que, pour les parametres typiques de l'electrodynamique quantique en circuit, un accord quantitatif requiert un modele en reponse non lineaire du champ intra-resonateur, tel que celui developpe. Dans un regime de forte puissance de spectroscopie, des bandes laterales apparaissent et sont causees par les fluctuations quantiques du champ electromagnetique. As a result of continued distributed deformation in the Gulf Extensional Province along an oblique-divergent plate margin, active normal faulting is well manifest in southeastern Baja California.

By characterizing normal-fault related deformation along the San Juan de los Planes fault zone SJPFZ southwest of La Paz, Baja California Sur we contribute to understanding the patterns and rates of faulting along the southwest gulf-margin fault system. The geometry, history, and rate of faulting provide constraints on the relative significance of gulf-margin deformation as compared to axial system deformation.

The active scarp-forming fault juxtaposes bedrock in the footwall against Late Quaternary sandstone-conglomerate. The scarps are separated by stretches of bedrock embayed by hundreds of meters-wide tongues of Quaternary sandstone-conglomerate, implying low Quaternary slip rate. Analyses of sediments from the vicinity of active methane seeps have uncovered a particular suite of lipid biomarker patterns that characterize methane consuming archaea and their syntrophic, sulfate reducing partners. These isoprenoid biomarkers, largely identified by their anomalously light carbon isotopic signatures, have been a topic of intense research activity and are recorded in numerous methane-rich environments from Holocene to Cenozoic.

This phenomenon has implications for depleted kerogens at 2. In contrast, the lipid biosignatures of methane producing archaea are not readily identified through distinct isotopic labels and have received comparably little attention in analyses of archaea in environmental samples. Indeed, environmental analyses generally detect only free archaeal lipids, not the intact, polar molecules found in the membrane of living organisms. The aim of this study was to develop methods by which we could identify the organisms responsible for methane generation in this environment.

While the ester-bound fatty acids, hopanoids and wax esters provide a means to identify most of the bacterial components of these mats, the archaea which Ere evidently present through genomic assays and the fact of intense methane production Hoehler et al. Archaeal core lipids present a number of analytical challenges. The core lipids of methanogens comprise C20, C40 and sometimes C25 isoprenoid chains, linked through ether bonds to glycerol.

As well as archaeal C20 , sn and snhydroxyarchaeol are associated particularly with methylotrophic methanogens. Actes des journees de linguistique: Colloque sur la recherche etudiante Proceedings of the Linguistics Conference: Presentations by students at a colloquium on student research on the occasion of the 50th anniversary of the University of Laval's Faculty of Letters, March , , include: Validation materielle d'une architecture generique de reseaux avioniques basee sur une gestion modulaire de la redondance.

Les systemes avioniques ne cessent d'evoluer depuis l'apparition des technologies numeriques au tournant des annees Apres le passage par plusieurs paradigmes de developpement, ces systemes suivent maintenant l'approche " Integrated Modular Avionics " IMA depuis le debut des annees Contrairement aux methodes anterieures, cette approche est basee sur une conception modulaire, un partage de ressources generiques entre plusieurs systemes et l'utilisation plus poussee de bus multiplexes. La plupart des concepts utilises par l'architecture IMA, bien que deja connus dans le domaine de l'informatique distribuee, constituent un changement marque par rapport aux modeles anterieurs dans le monde avionique.

Ceux-ci viennent s'ajouter aux contraintes importantes de l'avionique classique telles que le determinisme, le temps reel, la certification et les cibles elevees de fiabilite. L'adoption de l'approche IMA a declenche une revision de plusieurs aspects de la conception, de la certification et de l'implementation d'un systeme IMA afin d'en tirer profit.

Cette revision, ralentie par les contraintes avioniques, est toujours en cours, et offre encore l'opportunite de developpement de nouveaux outils, methodes et modeles a tous les niveaux du processus d'implementation d? Dans un contexte de proposition et de validation d'une nouvelle architecture IMA pour un reseau generique de capteurs a bord d? Afin de remedier a certaines des differentes lacunes identifiees, nous avons propose une approche de validation basee sur une plateforme materielle reconfigurable ainsi qu'une nouvelle approche de gestion de la redondance pour l'atteinte des cibles de fiabilite.

Dans une premiere partie, essentiellement bibliographique, nous introduisons quelques concepts de base relies aux proprietes magnetiques et de transport des multicouches metalliques. Ensuite, nous presentons une breve description des methodes d'analyse des resultats. Nous montrerons qu'une interpretation coherente de ces proprietes necessite la prise en consideration des effets des interfaces. Nous nous attacherons a mettre en evidence, a evaluer et a etudier les effets de ces interfaces ainsi que leur evolution, et ce, suite a des traitements thermiques tel que le depot a temperature elevee et l'irradiation ionique.

Cette partie debutera par l'analyse des proprietes d'une multicouche hybride, intermediaire entre les multicouches et les materiaux granulaires. Nous analyserons a l'aide des mesures de diffraction, de relaxation superparamagnetique et de magnetoresistance, les evolutions structurales produites par l'irradiation ionique. Nous etablirons des modeles qui nous aideront a interpreter les resultats pour une serie des multicouches qui couvrent un large eventail de differents comportements magnetiques.

Quantitative assessment of radio- and chemotherapy response with 18 F-FDG whole-body PET has attracted increasing interest in recent years. In most published work, SUV has been used for this purpose. In the context of therapy response assessment, the reliability of lesion SUVs, notably their test-retest stability, thus becomes crucial. For each patient, up to 7 tumor lesions were evaluated. Blood SUV was determined as the mean value of a 3-dimensional aortic region of interest that was delineated on the attenuation CT image and transferred to the PET image.

TRV was quantified as 1. The Loreto area of Baja California Sur , Mexico, contains a diverse association of igneous, sedimentary, and metasedimentary rocks exposed in the foothills and arroyos between the Sierra La Giganta and Gulf of California. The Loreto area was selected for this study to examine the possible relation of the marine rocks to the opening of the Gulf of California, and to determine the stratigraphic and structural relations between basement rocks composed of granitic and prebatholithic rocks and overlying Tertiary mainly Miocene sedimentary and volcanic rocks, and by a sequence of Pliocene marine and nonmarine sedimentary rocks.

The Pliocene marine rocks lie in a structural depression informally called here, the Loreto embayment. This geologic map and report stem from a cooperative agreement between the U. The area north of La Paz is characterized by the occurrence of several slump bodies, which are displaced by normal faults connected with the rift opening. In some places we have identified 's m scale thrust-related folds and reverse faults that we have interpreted as shortening features. The latter displace the slump layers and are offset by the normal faults. If confirmed, this would represent the first report of a shortening event in the Early Miocene volcaniclastic deposits of Baja California Sur.

The rocks affected by shortening have ages between 24 and 21 Ma, and are capped by undeformed volcanic rocks with ages spanning between These relationships define an intra-Early Miocene unconformity, which we interpret to be related to the shortening deformation. The available timing constraints allow us to infer that a main ENE-to-ESE-trending shortening was short-lived, possibly ca.

The account of this shortening event may shed some light on the complex subduction and microplate processes that preceded the continental rifting of the Gulf of California.
