description: Un mix énergétique large doit permettre de tirer profit de chaque technologie pour mener une transition énergétique efficace et résiliante mais sa faisabilité repose sur le stockage. Les secteurs de la métallurgie, des céramiques, du verre, du solaire thermique à concentration, de la chimie etc. doivent envisager le stockage de l'énergie thermique pour y parvenir. Jusqu'à présent, le choix des matériaux considérés pour les unités de stockage pour une gamme de températures de travail variant entre 300 et 600$^{\circ}$C concerne les matériaux à changement de phase. Il s'agit principalement de compositions eutectiques qui présentent l'avantage de se comporter comme des corps purs : leur fusion est congruente et se produit à température constante. Cependant, l'étude théorique de diagrammes de phase de systèmes binaires à base de sels a montré que les composés péritectiques stœchiométriques ont, en moyenne, des densités énergétiques deux à trois fois supérieures à celles des matériaux à changement de phase utilisés (sels fondus) dans les centrales solaires à concentration déjà existantes, comme Archimedes en Italie par exemple. Cette performance est liée à une réaction chimique réversible qui vient s'ajouter à la transition solide/liquide lors du processus de décharge d'énergie thermique du matériau. Ce travail présente le cas d'étude du péritectique $\unit{Li_4Br(OH)_3}$ issu du mélange $\unit{LiOH}/\unit{LiBr}$. Si Honnerscheid et al. ont démontré expérimentalement l'existence de $\unit{Li_4Br(OH)_3}$, celui-ci n'a jamais été synthétisé en quantité suffisante pour être caractérisé. Les résultats prouvent qu'il est possible de synthétiser $\unit{Li_4Br(OH)_3}$ par voie thermique classique en dépit de la très grande hygroscopicité des produits initiaux. Sa morphologie a ensuite été comparée à celle issue de la synthèse in situ et en temps réel dans la chambre d'un microscope électronique à balayage. Leurs signatures ont été validées par des essais de diffraction par rayons X. Les résultats préliminaires de caractérisation thermique montrent un potentiel énergétique élevé de $\unit{Li_4Br(OH)_3}$ comme matériau pour des unités de stockage de la chaleur compactes, ne nécessitant pas la mise en place d'une technologie complexe.

description: Objective: To estimate the contributions of biological aging, historical trends, and birth cohort effects on trends in pre-eclampsia in the United States. Design: Population based retrospective study. Setting: National hospital discharge survey datasets, 1980-2010, United States. Participants: 120 million women admitted to hospital for delivery. Main outcome measures: Temporal changes in rates of mild and severe pre-eclampsia in relation to maternal age, year of delivery, and birth cohorts. Poisson regression as well as multilevel age-period-cohort models with adjustment for obesity and smoking were incorporated. Results: The rate of pre-eclampsia was 3.4%. The age-period-cohort analysis showed a strong age effect, with women at the extremes of maternal age having the greatest risk of pre-eclampsia. In comparison with women delivering in 1980, those delivering in 2003 were at 6.7-fold (95% confidence interval 5.6-fold to 8.0-fold) increased risk of severe pre-eclampsia. Period effects declined after 2003. Trends for severe pre-eclampsia also showed a modest birth cohort effect, with women born in the 1970s at increased risk. Compared with women born in 1955, the risk ratio for women born in 1970 was 1.2 (95% confidence interval 1.1 to 1.3). Similar patterns were also evident for mild pre-eclampsia, although attenuated. Changes in the population prevalence of obesity and smoking were associated with period and cohort trends in pre-eclampsia but did not explain the trends. Conclusions Rates of severe pre-eclampsia have been increasing in the United States and age-period-cohort effects all contribute to these trends. Although smoking and obesity have driven these trends, changes in the diagnostic criteria may have also contributed to the age-period-cohort effects. Health consequences of rising obesity rates in the United States underscore that efforts to reduce obesity may be beneficial to maternal and perinatal health.

Recently, we constructed a semi-realistic model which contains the minimal supersymmetric standard model (MSSM) using an Ansatz of magnetic fluxes and orbifolding projections. However, we can consider more various configurations of magnetic fluxes and orbifolding projections preserving four-dimensional ${\cal N}=1$ supersymmetry. We research systematically such possibilities for leading to MSSM-like models and study their phenomenological aspects.

Ventilating the empire: environmental machines in the British Atlantic world, 1700-1850
Creators: name: Sampson, Paul E.
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation provides a scientific and social history of ventilation in the British Atlantic World during the long eighteenth century. Emerging amidst the enlightened craze for improvement, the first ventilating machines, or “ventilators,” aimed to extend the providential balance of particles in the atmosphere into enclosed and crowded spaces. These machines were widely adopted in the Royal Navy and in English prisons, where their use was promoted as a cornerstone of institutional reform. Early advocates of ventilation like the experimenter and clergyman Stephen Hales promised that his ventilators would thoroughly refresh these dank, putrid spaces and preserve the health of sailors, slaves and prisoners. In ships, ventilators were proposed as a means of mitigating the dangers of transition between climates, thus preserving the valuable labor resource of skilled sailors. In prisons, ventilation was proposed as a means of excluding and curing both moral and physical contagion in the new “perflated” and strictly disciplined prisons. By the end of the eighteenth century, however, the failures of ventilation to fully extinguish epidemic disease was accompanied by the emergence of tropical medicine, which essentialized hot, humid environments as unhealthy and impossible to ventilate. This led to claims by abolitionists that slave ships constituted such an irredeemable space, and to claims by prison reformers that both the moral and physical environments of prisoners had to be completely controlled. Contemporaneously, the rationale for ventilation was changing as new chemical conceptions of air proposed by Joseph Priestley and Antoine Lavoisier emphasized the quality and temperature of air over its free circulation. These developments, and the commodification of ventilating devices by the Marquis de Chabannes and others led sanitary reformers and chemical experts like David Boswell Reid to prioritize comfortable temperatures and air purification rather than open access to the external air. These developments led to ventilation devices becoming luxury goods that aimed to provide a comfortable atmosphere insulated from the miasma and filth of the emerging industrial city. In summation, I argue that while ventilating machines were initially designed to mitigate the negative environmental and social effects of empire through free circulation of air, the fear of hot, humid, putrid, “tropical” environments transformed ventilation into an infrastructural technology which ultimately aimed to insulate certain elements of society from others. By tracing the history of ventilating devices, Ventilating the Empire provides a cautionary tale of how racial and class dynamics can exert a strong influence on technological projects to avert environmental danger.

description: Solar filaments exhibit a range of eruptive-like dynamic activity, ranging from the full or partial eruption of the filament mass and surrounding magnetic structure as a coronal mass ejection (CME), to a fully confined or 'failed' eruption. On 2011 June 7, a dramatic partial eruption of a filament was observed by multiple instruments on SDO and STEREO. One of the interesting aspects of this event is the response of the solar atmosphere as non-escaping material falls inward under the influence of gravity. The impact sites show clear evidence of brightening in the observed EUV wavelengths due to energy release. Two plausible physical mechanisms explaining the brightening are considered: heating of the plasma due to the kinetic energy of impacting material compressing the plasma, or reconnection between the magnetic field of low-lying loops and the field carried by the impacting material. By analyzing the emission of the brightenings in several SDO/AIA wavelengths, and comparing the kinetic energy of the impacting material (7.6 x 10^26 - 5.8 x 10^27 ergs) to the radiative energy (1.9 x 10^25 - 2.5 x 10^26 ergs) we find the dominant mechanism of energy release involved in the observed brightening is plasma compression.

description: Le bois, matériau vivant, présente une structure complexe qui rend difficile l'analyse des phénomènes thermiques à l'échelle microscopique, afin de faire le lien entre les caractéristiques thermiques de chaque constituant et un comportement global. L'idée est ici de chercher à effectuer l'identification des paramètres intrinsèques des différents constituants d'un bois, à partir d'un modèle numérique issu de la tomographie d'un volume élémentaire de référence de quelques millimètres. Dans cette procédure inverse, le modèle numérique de grande taille va nécessiter l'utilisation de modèles réduit modaux. Dans des travaux précédents, nous avons montré l'intérêt de ce type de modèles réduits pour des applications d'estimation de sources [1] ou de caractérisation [2]. La méthode de réduction utilisée ici s'appuie sur des bases de Dirichlet-Steklov, particulièrement adaptées à des problèmes de grandes tailles, pour lesquels les caractéristiques thermiques peuvent évoluer. Ce modèle réduit est couplé à une technique d'optimisation PSO (Particle Swarm Optimization) afin déterminer le tenseur de conductivité ainsi que la capacité thermique de chaque structure du bois.

description: We measured velocities of 862 individual red giant stars in seven isolated dwarf galaxies in the Local Group: NGC 6822, IC 1613, VV 124 (UGC 4879), the Pegasus dwarf irregular galaxy (DDO 216), Leo A, Cetus, and Aquarius (DDO 210). We also computed velocity dispersions, taking into account the measurement uncertainties on individual stars. None of the isolated galaxies is denser than the densest Local Group satellite galaxy. Furthermore, the isolated dwarf galaxies have no obvious distinction in the velocity dispersion--half-light radius plane from the satellite galaxies of the Milky Way and M31. The similarity of the isolated and satellite galaxies' dynamics and structural parameters imposes limitations on environmental solutions to the too-big-to-fail problem, wherein there are fewer dense dwarf satellite galaxies than would be expected from cold dark matter simulations. This data set also has many other applications for dwarf galaxy evolution, including the transformation of dwarf irregular into dwarf spheroidal galaxies. We intend to explore these issues in future work.

description: The formation of bound electron-hole pairs, also called charge-transfer (CT) states, in organic-based photovoltaic devices is one of the dominant loss mechanisms hindering performance. While CT state dynamics following electron transfer from donor to acceptor have been widely studied, there is not much known about the dynamics of bound CT states produced by hole transfer from the acceptor to the donor. In this letter, we compare the dynamics of CT states formed in the different charge-transfer pathways in a range of model systems. We show that the nature and dynamics of the generated CT states are similar in the case of electron and hole transfer. However the yield of bound and free charges is observed to be strongly dependent on the HOMOD-HOMOA and LUMOD-LUMOA energy differences of the material system. We propose a qualitative model in which the effects of static disorder and sampling of states during the relaxation determine the probability of accessing CT states favourable for charge separation.

description: X-ray emission from the supermassive binary system Eta Carinae declines sharply around periastron. This X-ray minimum has two distinct phases - the lowest flux phase in the first ~3 weeks and a brighter phase thereafter. In 2009, the Chandra X-ray Observatory monitored the first phase five times and found the lowest observed flux at ~1.9e-12 ergs cm-2 s-1 (3-8 keV). The spectral shape changed such that the hard band above ~4 keV dropped quickly at the beginning and the soft band flux gradually decreased to its lowest observed value in ~2 weeks. The hard band spectrum had begun to recover by that time. This spectral variation suggests that the shocked gas producing the hottest X-ray gas near the apex of the wind-wind collision (WWC) is blocked behind the dense inner wind of the primary star, which later occults slightly cooler gas downstream. Shocked gas previously produced by the system at earlier orbital phases is suggested to produce the faint residual X-ray emission seen when the emission near the apex is completely blocked by the primary wind. The brighter phase is probably caused by the re-appearance of the WWC plasma, whose emissivity significantly declined during the occultation. We interpret this to mean that the X-ray minimum is produced by a hybrid mechanism of an occultation and a decline in emissivity of the WWC shock.

description: In rare-earth doped single crystalline CaFe2As2, the mysterious small volume fraction which superconducts up to 49 K, much higher than the bulk Tc ~ 30s K, has prompted a long search for a hidden variable that could enhance the Tc by more than 30% in iron-based superconductors of the same structure. Here we report a chemical, structural, and magnetic study of CaFe2As2 systematically doped with La, Ce, Pr, and Nd. Coincident with the high Tc phase, we find extreme magnetic anisotropy, accompanied by an unexpected doping-independent Tc and equally unexpected superparamagnetic clusters associated with As vacancies. These observations lead us to conjecture that the tantalizing Tc enhancement may be associated with naturally occurring chemical interfaces and may thus provide a new paradigm in the search for superconductors with higher Tc.

description: Through the creation of spectral energy distributions for well-observed literature core-collapse supernovae (CCSNe), we present corrections to transform optical light curves to full bolometric light curves. These corrections take the form of parabolic fits to optical colours, with $B - I$ and $g - r$ presented as exemplary fits, while parameters for fits to other colours are also given. We find evolution of the corrections with colour to be extremely homogeneous across CCSNe of all types in the majority of cases, and also present fits for stripped-envelope and type II SNe separately. A separate fit, appropriate for SNe exhibiting strong emission due to cooling after shock breakout, is presented. Such a method will homogenise the creation of bolometric light curves for CCSNe where observations cannot constrain the emitted flux - of particular importance for current and future SN surveys where typical follow-up of the vast majority of events will occur only in the optical window, resulting in consistent comparisons of modelling involving bolometric light curves. Test cases for SNe 1987A and 2009jf using the method presented here are shown, and the bolometric light curves are recovered with excellent accuracy in each case.

description: Social tags inherent in online music services such as Last.fm provide a rich source of information on musical moods. The abundance of social tags makes this data highly beneficial for developing techniques to manage and retrieve mood information, and enables study of the relationships between music content and mood representations with data substantially larger than that available for conventional emotion research. However, no systematic assessment has been done on the accuracy of social tags and derived semantic models at capturing mood information in music. We propose a novel technique called Affective Circumplex Transformation (ACT) for representing the moods of music tracks in an interpretable and robust fashion based on semantic computing of social tags and research in emotion modeling. We validate the technique by predicting listener ratings of moods in music tracks, and compare the results to prediction with the Vector Space Model (VSM), Singular Value Decomposition (SVD), Nonnegative Matrix Factorization (NMF), and Probabilistic Latent Semantic Analysis (PLSA). The results show that ACT consistently outperforms the baseline techniques, and its performance is robust against a low number of track-level mood tags. The results give validity and analytical insights for harnessing millions of music tracks and associated mood data available through social tags in application development.

description: Dans le but de contribuer à la valorisation de l'énergie solaire et au développement des systèmes énergétiques, un système combiné permettant la production simultanée du froid et de l'électricité est étudié. Le système consiste à incorporer un éjecteur entre un cycle organique de Rankine et une boucle de réfrigération. Ce système puisera la chaleur nécessaire à son fonctionnement à partir d'un dispositif de concentration solaire de type miroir cylindro-parabolique permettant de réchauffer le fluide cyclé jusqu'au niveau de température et de pression désiré. Un modèle mathématique du concentrateur cylindro-parabolique permettant le contrôle de la température de sortie du fluide caloporteur est établit. Ce modèle tient en compte les effets de l'intensité solaire, l'état du ciel, les dimensions des collecteurs, les propriétés des matériaux, les propriétés des fluides et les conditions ambiantes. Les résultats de simulation du récepteur solaire cylindro-parabolique qui sont calculés heure par heure du lever du soleil jusqu'au coucher, sont introduits dans la simulation du système combiné (ORC - Système frigorifique à éjection). Une étude paramétrique est menée afin d'étudier les effets des paramètres clés tels que les températures de fonctionnement, la nature du fluide, etc. Une analyse exergo-économique est développée pour trouver la structure optimale et les paramètres de fonctionnement optimum qui minimisent le coût global du système, sous des contraintes imposées de fonctionnement.

description: Controlled defect creation is a prerequisite for the detailed study of disorder effects in materials. Here, we irradiate a graphene/Ir(111)-interface with low-energy Ar+ to study the induced structural changes. Combining computer simulations and scanning-probe microscopy, we show that the resulting disorder manifests mainly in the forms of intercalated metal adatoms and vacancy-type defects in graphene. One prominent feature at higher irradiation energies (from 1 keV up) is the formation of line-like depressions, which consist of sequential graphene defects created by the ion channeling within the interface -- much like a stone skipping on water. Lower energies result in simpler defects, down to 100 eV where more than one defect in every three is a graphene single vacancy.

description: Dans le milieu de la réfrigération, la réglementation des fluides de travail est de plus en plus contraignante. En effet, l'impact environnemental de certains de ces fluides (quantifié notamment par l'ODP et le GWP) les conduit à voir leur utilisation réduite voire interdite dans les prochaines années. Des efforts doivent donc être réalisés afin de proposer des alternatives à ces fluides : l'eau, dont l'ODP et le GWP sont nuls, fait partie de ces possibles alternatives. Cependant, son utilisation en climatisation est généralement liée à des conditions sub-atmosphériques dans l'évaporateur. Ces conditions d'ébullition particulières ont très peu été étudiées dans la littérature. D'après de précédentes études réalisées au laboratoire sur un canal d'évaporateur à plaque lisse, les transferts thermiques sont en majeure partie liés à l'évaporation d'un film liquide sur la paroi de l'évaporateur. Ce film est formé par croissance et éclatement des bulles de vapeur de taille centimétrique. Afin de maitriser la production frigorifique, il est nécessaire de maîtriser le film liquide et par conséquent de caractériser la dynamique des bulles de vapeur pendant l'ébullition nucléée et, plus particulièrement, la hauteur de projection après explosion. C'est l'objectif de cette étude. Des vidéos, capturées précédemment par caméra rapide, sont analysées à l'aide d'un programme Python développé spécifiquement afin de calculer les caractéristiques de la bulle. Il est notamment mis en évidence que la hauteur de projection est corrélée à la vitesse de croissance et la taille de la bulle avant éclatement.

description: Objective
This Agent paper (II of V on monitoring the tobacco use epidemic) summarizes the findings and recommendations of the Agent (product) Working Group of the November, 2002, National Tobacco Monitoring, Research and Evaluation Workshop.

Methods
The Agent Working Group evaluated the need to develop new surveillance systems for quantifying ingredients and emissions of tobacco and tobacco smoke and to improve methods to assess uptake and metabolism of these constituents taking into account variability in human smoking behavior.

Results
The toxic properties of numerous tobacco and tobacco smoke constituents are well known, yet systematic monitoring of tobacco products has historically been limited to tar, nicotine, and CO in mainstream cigarette smoke using a machine-smoking protocol that does not reflect human smoking behavior. Toxicity of smokeless tobacco products has not been regularly monitored. Tobacco products are constantly changing and untested products are introduced into the marketplace with great frequency, including potential reduced-exposure products (PREPs). The public health impact of new or modified tobacco products is unknown.

Conclusions
Systematic surveillance is recommended for mainstream smoke constituents such as polycyclic aromatic hydrocarbons (PAH), tobacco-specific nitrosamines (TSNA), total and free-base nicotine, volatile organic compounds, aromatic amines, and metals; and design attributes including tobacco blend, additives, and filter ventilation. Research on smoking topography is recommended to help define machine-smoking protocols for monitoring emissions reflective of human smoking behavior. Recommendations are made for marketplace product sampling and for population monitoring of smoking topography, emissions of toxic constituents, biomarkers of exposure and, eventually, risk of tobacco-related diseases.

Year: 2023

description: This article delves into the specialized word formation processes in legal and medical discourses and their far-reaching impact on professional communication. Within these domains, the use of classical roots, affixation, compounding, and neologisms is indispensable for achieving precision and clarity. While these linguistic intricacies enhance communication among experts, they also pose challenges in interdisciplinary settings and when communicating with non-specialists. The article reviews the literature on word formation in legal and medical contexts, highlighting the influence of classical languages and the role of affixes in shaping terminology. It also discusses the broader implications for professional communication and offers recommendations for making communication within and beyond these domains more inclusive and effective.

description: Dans ce travail, nous étudions numériquement la convection naturelle du nanofluide $\unit{Al_2O_3}$-eau dans un espace confiné. Il s'agit d'une enceinte annulaire verticale chauffée différentiellement soumise à un champ magnétique uniforme. La méthode des volumes finis avec l'algorithme SIMPLER est utilisée pour résoudre le système d'équations régissant l'écoulement magnétohydrodynamique (MHD). Les solutions sont présentées sous forme de lignes de courants, d'isothermes, de nombres de Nusselt locaux et moyens et de profils de vitesse pour différents nombres de Rayleigh ($10^4 \leqslant Ra \leqslant 10^6$), de diamètres de nanoparticules (dp = 13 et 47 nm), de fractions volumiques ($0 \leqslant \varphi \leqslant 0.09$) et différents nombres de Hartmann ($0 \leqslant Ha \leqslant 100$). Les résultats de la simulation ont indiqué que la taille des nanoparticules est d'une importance cruciale pour la détermination des propriétés des nanofluides, à savoir la viscosité et la conductivité thermique. On a constaté qu'une augmentation de la fraction volumique du nanofluide entraîne une diminution du nombre de Nusselt moyen sur la paroi interne du cylindre pour des nanoparticules de diamètre dp = 47 nm, sauf pour le cas dp = 13 nm, on a noté une diminution jusqu'à la valeur $\varphi$ = 0.05 et ensuite une augmentation du nombre moyen de Nusselt. Les résultats montrent aussi que le taux de transfert de chaleur augmente avec l'augmentation du nombre de Rayleigh mais diminue avec l'augmentation du nombre de Hartmann. De plus, le nombre moyen de Nusselt a diminué en augmentant le champ magnétique de toutes les fractions volumétriques de nanoparticules. Ainsi, une augmentation du nombre de Hartmann entraîne une augmentation de l'amélioration du transfert de chaleur, en particulier lorsque le champ magnétique est orienté radialement.

description: The present paper discusses the diffusion approximation of the linear Boltzmann equation in cases where the collision frequency is not uniformly large in the spatial domain. Our results apply for instance to the case of radiative transfer in a composite medium with optically thin inclusions in an optically thick background medium. The equation governing the evolution of the approximate particle density coincides with the limit of the diffusion equation with infinite diffusion coefficient in the optically thin inclusions.

description: This thesis uses oral history interviews with Australians who were in out-of-home care as children to discover aspects of their family lives before, during and after the time that they spent in institutionalised care. By carefully analysing oral history interviews I discover that these family lives can be more complicated than what is represented in public narratives about Forgotten Australians.

description: La faisabilité d'un compresseur d'hydrogène non mécanique de 70 MPa basé sur l'adsorption-désorption cyclique sur du charbon actif a été étudiée. Ce type de compresseur présente plusieurs avantages par rapport à un compresseur mécanique traditionnel à hydrogène, tels qu'une conception plus simple et l'absence de composants en mouvement. La compression provient d'un chauffage du système de 77 à 315 K, ce qui permet la désorption de l'hydrogène et l'augmentation de la pression de l'hydrogène. 70 MPa ont été atteints en chargeant en une seule étape l'hydrogène à 8 MPa. Un compresseur à adsorption-désorption pourrait ainsi faire partie d'un système de compression à deux étages, par exemple en aval d'un étage de compression préliminaire ou d'un électrolyseur haute pression et, in fine, pourrait être utilisé dans de petites installations utilisant l'hydrogène comme carburant, par exemple dans une station de ravitaillement en hydrogène. Le travail présenté ici se concentre sur la modélisation du compresseur et sa validation par comparaison avec le procédé expérimental. La compression de l'hydrogène et la décharge sont simulés par éléments finis. Le réservoir est modélisé par une géométrie 2D axisymétrique en résolvant les équations de la chaleur et de la conservation de la masse d'hydrogène. Les résultats présentés concerneront la validation du modèle par comparaison aux évolutions expérimentales (température, pression et débit en sortie). En complément, une étude paramétrique sera réalisée sur plusieurs paramètres (coefficient d'échange thermique, conductivité thermique, etc.).

description: Pour un assemblage métallique, un écart trop important de température de fusion pose un problème d'incompatibilité en soudage conventionnel. Le principe de formation de joint soudé par création d'un noyau fondu ne fonctionne plus en général, impliquant en cela la nécessité d'un autre mécanisme de formation de soudure. Une collision interfaciale intense sur une durée très brève constitue une solution éprouvée expérimentalement. Un joint soudé se forme lors d'une collision balistique. On parle alors de soudage par impact dont le critère de soudabilité est généralement décrit dans la littérature par l'obtention d'une forme ondulée qui résulte d'une cinématique complexe de l'interface lors de la propagation du point de collision pendant l'impact. Un modèle robuste basé sur une approche pseudo-eulérienne permet de reproduire cette réponse de l'interface et d'en comprendre les conséquences à l'échelle macroscopique sur le développement de plusieurs variances morphologiques d'interface observées expérimentalement, mais aussi à l'échelle microscopique pour expliquer les gradients de transformations métallurgiques à travers l'interface soudée. D'origine thermomécanique, ces phénomènes sont tous imputables à la forte vitesse de déformation pendant la collision balistique qui produit, à l'échelle macroscopique, une série d'instabilités cinématiques (phénomène de jet, d'éjection de matière, de déformation ondulatoire de l'interface, sillage, tourbillons et chemin de vortex), et à l'échelle microscopique, des phénomènes de nanostructuration ou d'amorphisation par effet de confinement de cisaillement adiabatique dont l'élévation de température créée peut aussi activer des cinétiques de précipitations ou de formation de dispersoïdes.

description: Between 1961 and 1971, U.S. military forces dispersed more than 19 million gallons of phenoxy and other herbicidal agents in the Republic of Vietnam, including more than 12 million gallons of dioxin-contaminated Agent Orange, yet only comparatively limited epidemiologic and environmental research has been carried out on the distribution and health effects of this contamination. As part of a response to a National Academy of Sciences' request for development of exposure methodologies for carrying out epidemiologic research, a conceptual framework for estimating exposure opportunity to herbicides and a geographic information system (GIS) have been developed. The GIS is based on a relational database system that integrates extensive data resources on dispersal of herbicides (e.g., HERBS records of Ranch Hand aircraft flight paths, gallonage, and chemical agent), locations of military units and bases, dynamic movement of combat troops in Vietnam, and locations of civilian population centers. The GIS can provide a variety of proximity counts for exposure to 9,141 herbicide application missions. In addition, the GIS can be used to generate a quantitative exposure opportunity index that accounts for quantity of herbicide sprayed, distance, and environmental decay of a toxic factor such as dioxin, and is flexible enough to permit substitution of other mathematical exposure models by the user. The GIS thus provides a basis for estimation of herbicide exposure for use in large-scale epidemiologic studies. To facilitate widespread use of the GIS, a user-friendly software package was developed to permit researchers to assign exposure opportunity indexes to troops, locations, or individuals.

description: A retrospective case-control hospital study of 785 Caucasian breast cancer patients and 2,231 age-stratified controls was conducted in New York City from 1969–1975. Patients were grouped by pre- peri- and postmenopausal status at diagnosis for the analysis to make a distinctive separation for variables showing a pre- and postmenopausal differential. Demographic characteristics were similar for cases and controls. Previously recorded hormone-related risk variables for this disease were largely confirmed for pre- and perimenopausal women, i.e., late age at first birth (greater than 25), premenstrual symptoms of breast swelling and premenopausal chills and flushes. Mother's history of breast cancer was also found to be a risk variable. Nulliparity was a risk factor only perimenopausally. No risk was found for absolute height, weight or for obesity (Quetelet Index), prior breast diseases or previous usage of exogenous hormones of any type and no “protective” effect was found for multiparous women and for nursing. Perimenopausally diagnosed patients (menopause to 10 years after) were similar to premenopausally diagnosed women on most risk factors. Risk variables determined by this and other case-control studies cannot account for the magnitude of differences in the international incidence of breast cancer.
