description: Lors d'un accident de perte de réfrigérant primaire (APRP), des injections de secours sont réalisées et un écoulement dispersé de vapeur et de gouttes se produit en aval du front de remouillage qui se propage dans les assemblages. Cet écoulement joue un rôle très important dans le refroidissement initial des cœurs en situation accidentelle ; c'est pourquoi la communauté nucléaire travaille depuis longtemps pour modéliser le plus correctement les échanges thermiques entre les crayons, la vapeur et les gouttes afin d'estimer le refroidissement des crayons combustibles. Dans un précédent travail, nous avons présenté le code NECTAR validé à l'aide de l'expérience COLIBRI. Dans ce code, la dissipation de chaleur et la dynamique de gouttes sont estimées avec une bonne précision pour un écoulement dispersé et pour différents taux de bouchage. Le code NECTAR, étant validé par des expériences, permet de réaliser des analyses paramétriques. Dans cet article, il s'agit d'analyser l'influence du débit massique des gouttes et de leurs distributions en taille sur les transferts thermiques. De plus, les conditions limites et initiales testées sont plus représentatives d'un APRP notamment celles concernant la température de vapeur et la fraction volumiques. La dissipation totale de chaleur interne est évaluée et on analyse les contributions des différents mécanismes en jeu.

description: There is currently a growing interest in techniques for hiding parts of the signature of an ontology Kh that is being reused by another ontology Kv. Towards this goal, in this paper we propose the import-by-query framework, which makes the content of Kh accessible through a limited query interface. If Kv reuses the symbols from Kh in a certain restricted way, one can reason over Kv U Kh by accessing only Kv and the query interface. We map out the landscape of the import-by-query problem. In particular, we outline the limitations of our framework and prove that certain restrictions on the expressivity of Kh and the way in which Kv reuses symbols from Kh are strictly necessary to enable reasoning in our setting. We also identify cases in which reasoning is possible and we present suitable import-by-query reasoning algorithms.

description: La projection à froid est une méthode de fabrication additive qui utilise un écoulement supersonique diphasique fluide/poudres micrométriques pour élaborer une structure par collision balistique. L'interaction thermique entre l'écoulement et les poudres affecte le processus de croissance additive de matière. Dans la littérature, on a recours généralement à la simulation numérique pour estimer la température des poudres à une position spatiale dans le jet en les considérant comme une phase discrète dont la température est supposée instantanément uniforme. On peut vérifier cette hypothèse à partir d'une comparaison de temps caractéristique correspondant au temps de résidence des poudres dans le jet lorsqu'elles parcourent des distances infinitésimales, et au temps d'établissement d'un gradient thermique quasi-uniforme au sein des poudres. L'écart significatif entre ces deux temps caractéristiques, pour des distances parcourues de l'ordre de la taille des poudres, montre que la notion de température uniforme instantanée n'est pas toujours vraie. C'est une notion subjective qui est valable en choisissant une unité de distance infinitésimale dx=1mm qui est en effet l'unité de référence dans la littérature pour simuler l'interaction écoulement/poudre. La solution analytique de la température en coordonnée radiale donne une corrélation analytique adimensionnelle indiquant des conditions paramétrées de température instantanément uniforme.

description: Persistent identifiers, such as Digital Object Identifiers (DOIs), can contribute to the discovery and access of online scientific data and related web-based resources over time. In addition to enabling continuing access to scientific data when persistent identifiers are maintained, DOIs also can contribute to the attribution of scientific data. Assigning DOIs to datasets and registering them for inclusion in open catalogs enables discovery of the metadata records by facilitating harvesting and indexing by other catalogs where the data can be discovered and accessed through the DOIs that serve as resolvable links to the landing pages for the scientific data. Similar to other publications that are cited in research articles, the DOIs for data can be included in the reference to the data when citing the data used for preparation of a research publication. Examples of landing pages and recommended citations for scientific data that are available from the NASA Socioeconomic Data! and Applications Center (SEDAC) demonstrate how access to scientific data can be facilitated through the assignment of DOIs and show how guidance may be provided for users of scientific data to provide attribution to the data that they use in their research.

description: We present an analysis of recent high spatial and spectral resolution ground-based infrared observations of H3+ spectra obtained with the 10-metre Keck II telescope in April 2011. We observed H3+ emission from Saturn's northern and southern auroral regions, simultaneously, over the course of more than two hours, obtaining spectral images along the central meridian as Saturn rotates. Previous ground-based work has derived only an average temperature of an individual polar region, summing an entire night of observations. Here we analyse 20 H3+ spectra, 10 for each hemisphere, providing H3+ temperature, column density and total emission in both the northern and southern polar regions simultaneously, improving on past results in temporal cadence and simultaneity. We find that: 1) the average thermospheric temperatures are 527+/-18 K in northern Spring and 583+/-13 K in southern Autumn, respectively; 2) this asymmetry in temperature is likely to be the result of an inversely proportional relationship between the total thermospheric heating rate (Joule heating and ion drag) and magnetic field strength - i.e. the larger northern field strength leads to reduced total heating rate and a reduced temperature, irrespective of season, and 3) this implies that thermospheric heating and temperatures are relatively insensitive to seasonal effects.

Possible institutions: literature festivals and talk-culture in India
Creators: name: Sivaram, Sushil
Publisher: name: No Publisher Supplied
Year: 2020

description: This dissertation sets out to understand the proliferation of literature festivals in India since the mid-2000s. These festivals serve cultural, economic and political functions in a dynamic field characterized by varying degrees of competition and co-operation between different literary cultures in multiple languages, the uneven legitimation and reception of culture by different class formations, and the multiple locations where the humanities are practiced. Against this complex setting, I demonstrate that the literature festivals attempt to find unique ways to connect and in turn reimagine a fragmented and plural literary field in the public sphere. This work specifically turns to the producers, managers and the writer-curators of three festivals to understand what drives them and the festivals they curate to produce a network of legitimation for literature in India. The festivals I engage with are the “Jaipur Literature Festival,” the “Indian Languages Festival: Samanvay” and the “Almost Island Dialogues.” I claim that these festivals connect and reimagine the field via a mode of interaction that I call “talk-culture.” As a form of purposeful and conscious (re)turn to conjunctural networks of literary sociality and older forms of public communication, talk-culture is an intimate, face-to-face practice that is a combination of the literary and the critical. In other words, talk-culture is a type of connectivity and framework to reconstitute community. Each chapter locates dispositions and attitudes that emerge out of interactions between writer-curators, the guest speakers, the topics of discussion, audience responses, interviews I conducted with writer-curators, and participant observation. At all three festivals, the possibility of change lies in performing different versions of literary histories and producing knowledges without objectifying or institutionalizing them. This I claim makes their practices ephemeral and engenders attitudes towards literature and literary culture that do not aim towards explicit rulemaking, objectivity and systemization, but at the same time offer a sense of community that performances simulate. That is why I call these events “possible institutions.” The significance of this dissertation rests in the possibility of new academic and non-academic approaches to literature and literary cultures in India. In turning to practices on the ground, the project demonstrates that the often unrehearsed and unintentional practices of writers-curators and the festivals offer alternative ways to approach the complexities of a fragmented, plural, and multilingual literary field. Moreover, this work, attempts to learn from and at the same time support the knowledges that the writer-curators and the festivals produce in the public sphere. The specific literature festivals in this dissertation are spaces where new ways to practice an alternate relationship to literature and literary culture could emerge.
Avoiding and Escaping Depressions in Real-Time Heuristic Search

description: Heuristics used for solving hard real-time search problems have regions with depressions. Such regions are bounded areas of the search space in which the heuristic function is inaccurate compared to the actual cost to reach a solution. Early real-time search algorithms, like LRTA*, easily become trapped in those regions since the heuristic values of their states may need to be updated multiple times, which results in costly solutions. State-of-the-art real-time search algorithms, like LSS-LRTA* or LRTA*(k), improve LRTA*s mechanism to update the heuristic, resulting in improved performance. Those algorithms, however, do not guide search towards avoiding depressed regions. This paper presents depression avoidance, a simple real-time search principle to guide search towards avoiding states that have been marked as part of a heuristic depression. We propose two ways in which depression avoidance can be implemented: mark-and-avoid and move-to-border. We implement these strategies on top of LSS-LRTA* and RTAA*, producing 4 new real-time heuristic search algorithms: aLSS-LRTA*, daLSS-LRTA*, aRTAA*, and daRTAA*. When the objective is to find a single solution by running the real-time search algorithm once, we show that daLSS-LRTA* and daRTAA* outperform their predecessors sometimes by one order of magnitude. Of the four new algorithms, daRTAA* produces the best solutions given a fixed deadline on the average time allowed per planning episode. We prove all our algorithms have good theoretical properties: in finite search spaces, they find a solution if one exists, and converge to an optimal after a number of trials.

description: All‐d Heuslers are a category of novel compounds combining versatile functionalities such as caloric responses and spintronics with enhanced mechanical properties. Despite the promising transport properties (anomalous Hall (AHC) and anomalous Nernst (ANC) conductivities) shown in the conventional Co₂XY Heuslers with p‐d hybridization, the all‐d Heuslers with only d‐d hybridization open a new horizon to search for new candidates with outstanding transport properties. In this work, the AHC and ANC are evaluated for thermodynamically stable ferro/ferri‐magnetic all‐d‐metal regular Heusler compounds based on high‐throughput first‐principles calculations. It is observed that quite a few materials exhibit giant AHCs and ANCs, such as cubic Re₂TaMn with an AHC of 2011 S cm⁻¹, and tetragonal Pt₂CrRh with an AHC of 1966 S cm⁻¹ and an ANC of 7.50 A m⁻¹K⁻¹. Comprehensive analysis on the electronic structure reveals that the high AHC can be attributed to the occurrence of the Weyl nodes or gapped nodal lines in the neighborhood of the Fermi level. The correlations between such transport properties and the number of valence electrons are also thoroughly investigated, which provides a practical guidance to tailor AHC and ANC via chemical doping for transverse thermoelectric applications.

description: Although the corresponding carbon-metal interactions can be very different, a similar nonlinear growth behavior of graphene has been observed for different metal substrates. To understand this interesting experimental observation, a multiscale $\lq\lq$standing-on-the-front" kinetic Monte Carlo study is performed. An extraordinary robust geometry effect is identified, which solely determines the growth kinetics and makes the details of carbon-metal interaction not relevant at all. Based on such a geometry-determined mechanism, epitaxial growth behavior of graphene can be easily predicted in many cases. As an example, an orientation-sensitive growth kinetics of graphene on Ir(111) surface has been studied. Our results demonstrate that lattice mismatch pattern at the atomic level plays an important role for macroscopic epitaxial growth.

description: The main aim of this study was to investigate the role of social factors in facilitating pro-social behavior among Arsi Negelle Preparatory school students. The research employed crosssectional research design of quantitative method. Out of 1170 grade eleven and twelve students, 299 students were selected were selected using stratified systematic random sampling technique. Descriptive statistics were computed to summarize the participants’ demographic characteristics and the most observed pro-social behavior type. Independent t -test was also used to test the significance mean difference between gender while one way ANOVA was employed to quantify the family income and parental education in facilitating pro-social behavior among students. The findings showed that among domain of pro-social behavior, complaint was the most observed pro-social behavior while altruism was the least observed pro-social behavior among students. There was a significant mean difference in score of overall pro-social behavior between male and female students. There was also statistically significant difference among respondents in their overall pro-social behavior and all types of pro-social behaviors score facilitated by their mother’s and father’s level of education. On the other hand, there was statistically insignificant difference among respondents in their overall pro-social behavior scores that can be facilitated by their family/guardian’s level of income. As a result, students were mostly involved in helping others in response to a verbal or nonverbal request. Moreover, being male or female and mother’s level of education has had an influence in involving pro-social behavior. However, family/guardian’s level of income difference has no influence in facilitating overall pro-social behavior. Based on the aforementioned implications, parents, teachers, neighbors, religious leaders, government and non-government bodies are recommended to play a role in promoting pro-social behavior among the students.
Development, characterization and application of silica-supported pincer-iridium catalysts for heterogeneous, continuous-flow alkane valorization
Creators: name: Sheludko, Boris
Publisher: name: No Publisher Supplied
Year: 2020

description: The production of olefins from alkanes is one of the most valuable industrial transformations currently in use, as hundreds of millions of tons of olefins are used globally per year to generate plastics, fuels and specialty chemicals. While most light olefins are obtained via high-temperature cracking processes, there has been recent interest in “on-purpose” alkane dehydrogenation. Pincer-iridium complexes of the form [(R4PCP)Ir] (R4PCP = κ3-C6H3-2,6-(XPR2)2; X = CH2, O; R = tBu, iPr), having been studied for several decades, are highly efficient and often regioselective alkane molecular dehydrogenation catalysts. The development of a system incorporating the active site of these materials into a heterogeneous catalyst could potentially be valuable and industrially applicable.In this work, such pincer-iridium species are immobilized on an amorphous silica support and the resultant materials are studied in a continuous gas-flow reactor to characterize their structure, thermal stability and kinetic properties. In chapter 3, the stability of these immobilized complexes is explored, and it is shown that immobilization increases the maximum temperature of stability from 240 °C to 300-340 °C, likely by eliminating bimolecular decomposition pathways. In chapter 4, in situ diffuse reflectance Fourier-transform IR spectroscopy is used to monitor the iridium speciation under reaction conditions. Carbon monoxide is shown to stabilize the catalyst against decomposition at elevated temperatures, likely by mitigating interaction of the iridium center with the silica support. Chapter 5 explores the behavior of such immobilized pincer iridium species under alkane transfer dehydrogenation conditions, and an effect on regioselectivity is observed that is dependent both on the nature and partial pressure of the olefinic sacrificial hydrogen acceptor. The resulting regioselectivity is explained via a model previously calculated via DFT for molecular species, supporting the fact that the active site remains unchanged upon immobilization. In chapter 6, the decomposition product of the immobilized pincer-iridium complex (tBu2PO-tBu4POCOP)Ir(L) (L = C2H4, CO) is shown to be a novel iridium phosphide nanophase via XAS, NMR and IR, that is stable against agglomeration on the silica surface and is an efficient alkane dehydrogenation catalyst as well.

A discussion of a geometric shape that became a symbol known as mandorla or vesica piscis, starting from a Pythagorean point of view

description: Here we propose a discussion about the "mandorla" or "vesica piscis". It is a type of 2-dimensional lens, that is, a geometric shape formed by the intersection of two circles with the same radius, intersecting in such a way that the centre of each circle lies on the perimeter of the other. The aim of the discussion is that of understanding when such a geometric shape became a symbol and when this symbol received a specific name. We will find that the name "mandorla" was used long before the term "vesica piscis", which is the Latin translation of the German "fischblosen" (fish-bladder) used by Albrecht Dürer in his book on geometry. Therefore, the name invented by Dürer was not used by the painter for a sacred form. However, after the middle of the nineteenth century the term "vesica piscis" exploded in literature. Its use was criticized and, at the same time, it was stressed that the proper term for the symbol is "mandorla". Nonetheless, the "vesica piscis" continues to be largely used in the sacred geometry, which ascribes symbolic and sacred meanings to certain geometric shapes and proportions. In the proposed discussion, we will also show that, recently, the 2-dimensional lenticular symbol has been related to the Pythagorean philosophy. It is told that the followers of this philosophy had the habit of using an apple for symbolic communications. Sliced across, the core of the apple is displaying a pentagram, but sliced lengthwise it forms two intersecting circles, that is a "mandorla". Then, the investigation about terms and related uses of this specific geometric shape is the core of the matter of our discussion or, let us tell, the "core of the apple", in a Pythagorean-like approach to find how a German "fischblosen" evolved into a sacred symbol, thanks to a translation into Latin.

description: Using a thermodynamical approach, we calculate the deformation of a spherical elastic particle placed on a rigid substrate, under zero external load, and including an ingredient of importance in soft matter: the interfacial tension of the cap. In a first part, we limit the study to small deformation. In contrast with previous works, we obtain an expression for the energy that precisely contains the JKR and Young-Dupré asymptotic regimes, and which establishes a continuous bridge between them. In a second part, we consider the large deformation case, which is relevant for future comparison with numerical simulations and experiments on very soft materials. Using a fruitful analogy with fracture mechanics, we derive the exact energy of the problem and thus obtain the equilibrium state for any given choice of physical parameters.

description: Une pale d'éolienne est une structure composite complexe généralement composée d'un revêtement (gelcoat), de polymère renforcé de fibres de verre (PRFV) et de fibres naturelles comme le balsa. Au cours de sa fabrication et de son service, de nombreux types de défauts peuvent apparaître, superficiels ou internes, tels que fissures, vides, corrosion, délaminage, etc. Ces défauts peuvent non seulement affecter l'efficacité énergétique de l'éolienne, mais aussi causer des dommages importants et réduire sa durée de vie. Par conséquent, une inspection régulière appropriée est souvent requise. Les inspections courantes dans l'industrie se font soit au moyen d'une nacelle, soit par dispositif télescopique depuis le sol. Comme les inspections visuelles ne peuvent pas détecter les défauts internes de la pale, des Contrôles non destructifs (CND) sont souvent réalisés en complément, que ce soient des tests par ultrasons ou par thermographie infrarouge. Dans ce travail, la thermographie passive est utilisée pour détecter un délaminage dans la zone stratifiée principale de la pale. Une telle inspection est réalisée en utilisant le soleil comme source naturelle de chauffage. Un contraste thermique apparaît alors entre une zone défectueuse et une zone normale lors de l'exposition au soleil, contraste qui devient détectable par thermographie au bout d'un temps variant de quelques minutes à une demi-heure environ. En laboratoire, le délaminage a été simulé par la réalisation, en face arrière d'un morceau de pale réelle, de trous à fond plat, dans lesquels est insérée une feuille de papier bulle, avant rebouchage par la même résine que celle constituant la pale. Au début de l'essai, cet échantillon a été déplacé de l'intérieur (température ambiante à 25~$^{\circ}$C) à l'extérieur sous l'irradiation solaire Des thermogrammes ont été enregistrés régulièrement toutes les 4 minutes de 0 à 32 minutes. Les résultats montrent que les défauts les moins profonds (insert à 3 mm et insert à 7 mm) peuvent être observés facilement dès les premières minutes, tandis que les contrastes thermiques maximaux pour les plus profonds ne sont observés qu'à des temps nettement plus longs, généralement autour de 15 minutes. Un modèle numérique a par ailleurs été construit afin de calculer le transfert de chaleur à l'intérieur d'un bicouche revêtement + structure composite, avec des profondeurs de délaminages différentes. Une source de chauffage constante permet de simuler l'effet du soleil, et un coefficient d'échange (h = 15~$\unit{W.m^{-2}.K{-1}}$) est utilisé pour prendre en compte les échanges convectifs. Selon ce modèle, la différence de température maximale est généralement atteinte à des temps compris entre 5 et 15 minutes, ce qui correspond bien aux résultats expérimentaux. Ces résultats sont également comparables à ceux rapportés par Worzewski.

description: The formation of unmagnetized electrostatic shock-like structures with a high Mach number is examined with one- and two-dimensional particle-in-cell (PIC) simulations. The structures are generated through the collision of two identical plasma clouds, which consist of equally hot electrons and ions with a mass ratio of 250. The Mach number of the collision speed with respect to the initial ion acoustic speed of the plasma is set to 4.6. This high Mach number delays the formation of such structures by tens of inverse ion plasma frequencies. A pair of stable shock-like structures is observed after this time in the 1D simulation, which gradually evolve into electrostatic shocks. The ion acoustic instability, which can develop in the 2D simulation but not in the 1D one, competes with the nonlinear process that gives rise to these structures. The oblique ion acoustic waves fragment their electric field. The transition layer, across which the bulk of the ions change their speed, widens and their speed change is reduced. Double layer-shock hybrid structures develop.

description: Rationale: Residents and area workers who inhaled dust and fumes from the World Trade Center disaster reported lower respiratory symptoms in two World Trade Center Health Registry surveys (2003–2004 and 2006–2007), but lung function data were lacking. Objectives: To examine the relationship between persistent respiratory symptoms and pulmonary function in a nested case–control study of exposed adult residents and area workers 7–8 years after September 11, 2001. Methods: Registrants reporting post September 11th onset of a lower respiratory symptom in the first survey and the same symptom in the second survey were solicited as potential cases. Registrants without lower respiratory symptoms in either Registry survey were solicited as potential control subjects. Final case–control status was determined by lower respiratory symptoms at a third interview (the study), when spirometry and impulse oscillometry were also performed. Measurements and Main Results: We identified 180 cases and 473 control subjects. Cases were more likely than control subjects to have abnormal spirometry (19% vs. 11%; P,0.05), and impulse oscillometry measurements of elevated airway resistance (R5; 68% vs. 27%; P,0.0001) and frequency dependence of resistance (R5–20; 36% vs. 7%; P , 0.0001). When spirometry was normal, cases were more likely than control subjects to have elevated R5 and R5–20 (62% vs. 25% and 27% vs. 6%, respectively; both P , 0.0001). Associations between symptoms and oscillometry held when factors significant in bivariate comparisons (body mass index, spirometry, and exposures) were analyzed using logistic regression. Conclusions: This study links persistent respiratory symptoms and oscillometric abnormalities in World Trade Center–exposed residents and area workers. ElevatedR5andR5–20 in cases despite normal spirometry suggested distal airway dysfunction as a mechanism for symptoms.

description: Background. Volunteers (non-professional rescue/recovery workers) are universally present at manmade and natural disasters and share experiences and exposures with victims. Little is known of their disaster-related health outcomes. Methods. We studied 4974 adult volunteers who completed the World Trade Center Health Registry 2006–07 survey to examine associations between volunteer type (affiliated vs. lay) and probable posttraumatic stress disorder (PTSD); new or worsening respiratory symptoms; post-9/11 first diagnosis of anxiety disorder, depression, and/or PTSD; and asthma or reactive airway dysfunction syndrome (RADS). Affiliated volunteers reported membership in a recognized organization. Lay volunteers reported no organizational affiliation and occupations unrelated to rescue/recovery work. Adjusted odds ratios (ORadj) were calculated using multinomial regression. Results. Lay volunteers were more likely than affiliated volunteers to have been present in lower Manhattan, experience the dust cloud, horrific events and injury on 9/11 and subsequently to report unmet healthcare needs. They had greater odds of early post-9/11 mental health diagnosis (ORadj 1.6; 95% CI: 1.4–2.0) and asthma/RADS (1.8; 1.2–2.7), chronic PTSD (2.2; 1.7–2.8), late-onset PTSD (1.9; 1.5–2.5), and new or worsening lower respiratory symptoms (2.0; 1.8–2.4). Conclusions. Lay volunteers' poorer health outcomes reflect earlier, more intense exposure to and lack of protection from physical and psychological hazards. There is a need to limit volunteers' exposures during and after disasters, as well as to provide timely screening and health care post-disaster.

title: Determination of the controlling parameters for dislocation nucleation in SrTiO₃: An investigation by nanoindentation

description: We conduct nanoindentation to investigate dislocation nucleation in SrTiO₃ (STO) single crystals with surface orientations of (0 0 1), (0 1 1), and (1 1 1) with loading/unloading rates of 25, 250, and 2500 μN/s. Results reveal that the critical loads (Pc) at which “pop‐in” event occurs depend strongly on surface orientations, but slightly related to loading rate. Based on Pc, the critical shear stress that triggers dislocation nucleation was determined by extracting the maximum resolved shear stress (τmax) along the slip systems of STO using the Hertzian solution. The dislocation activation shear stress (τa) was determined by averaging τmax. The determined τa is 9.0–12.0 GPa, close to the shear strength (∼G/2π) of STO, indicating that homogeneous dislocation nucleation dominates the pop‐in events. The consistency of the determined τa demonstrates that the frameworks for nanoindentation pop‐in analysis established for metals can be extended to ceramics, whereas the influence of the limited slip systems should be taken into consideration. Additionally, we estimated the activation volume and the activation energy via the statistical model proposed by Schuh et al. The small values of the determined activation volume (0.6–9.8 Å³) and the activation energy (0.13–0.70 eV) indicate that the dislocation nucleation possibly begins from a single‐atom migration and local point defects may participate in the dislocation nucleation process. That is, heterogeneous nucleation may exist initially but the homogeneous dislocation nucleation dominates the pop‐in events.

description: Background: Pesticides are widely used in households to control insects and weeds. Several studies over the past decades have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We therefore present a case-control study examining self-reported exposure to household pesticides with regard to associated risk of breast cancer. Methods: This study was conducted in the two largest hospitals serving Eastern Queens county (New York City) and the two New York State counties that make up Long Island. It included 1205 patients (447 cases and 758 controls). Cases were defined as women with newly diagnosed breast cancer or carcinoma in-situ, while controls included women with benign breast diseases or those undergoing non-breast related surgery. All patients were asked a series of questions to determine their pesticide exposure, including the type of pesticide, location of exposure (inside vs. outside the home), who applied the pesticide (self vs. a professional) and duration of pesticide use. Logistic regression models were used to estimate unadjusted and adjusted odds ratios (OR) and corresponding 95% confidence intervals (CI). Results: The most common pests encountered in participants’ homes were ants, carpenter ants, and cockroaches. The adjusted odds ratios for both self and professionally applied pesticides, specifically against the above mentioned insects, with regard to breast cancer risk were 1.25 (95% CI: 0.79-1.98) and 1.06 (95% CI: 0.65-1.73), respectively. Similarly, odds ratios and confidence intervals were calculated for other types of pesticides. Conclusions: Overall, the results of our study did not show an association between self-reported exposure to pesticides and breast cancer risk. Future studies, utilizing a larger sample size and more specific detail on time frame of pesticide exposure, are needed to further explore this question.

description: La production d'huile d'olive a une énorme importance socio-économique dans la région méditerranéenne. Cependant, l'extraction de l'huile d'olive génère d'énormes quantités de déchets qui ont des impacts négatifs sur les milieux terrestres et aquatiques en raison de leur phytotoxicité. Les boues des eaux usées des moulins à huile d'olives (OMWWS, Olive Mill Waste Water Sludges) sont l'un des principaux polluants dans l'industrie d'huile d'olive. Pour éviter les graves effets des OMWWS, il est nécessaire de convertir ce polluant en produits utiles tels que la bio-huile, le biochar et le biogaz. La pyrolyse est l'une des technologies de conversion thermochimique les plus importantes actuellement disponibles car elle produit à la fois des solides, des vapeurs condensables et des produits gazeux non condensables. Dans notre travail, la pyrolyse des OMWWS a lieu à 450$^{\circ}$C et les produits sont progressivement refroidis dans deux condenseurs connectés en série. L'huile biologique est condensée dans le 1er condenseur à 90$^{\circ}$C tandis que les vapeurs d'eau sont condensées dans le 2ème condenseur à 10$^{\circ}$C. Un modèle du procédé de pyrolyse des OMWWS est développé avec ASPEN (Advanced System for Process Engineering) Plus. Cet outil est utilisé pour mener une analyse énergétique et exergétique du procédé pour chaque composant utilisé dans la pyrolyse en fonction des conditions d'exploitation et des propriétés physiques et chimiques de la ressource en biomasse et des produits. Vu les températures élevées impliquées dans ce procédé, en particulier au niveau des gaz chauds, il existe un potentiel de récupération de chaleur pour la production de froid par adsorption afin de fournir le vecteur frigoporteur nécessaire à la condensation. Notre objectif est de maximiser la production de froid et par conséquent l'efficacité de la production des bio-huiles.

description: We present the results of the spectropolarimetric study of the classical Cepheid $η$ Aql in 2002, 2004, 2010, and 2012. The longitudinal magnetic field of $η$ Aql was found to be variable with the pulsation cycle of 7.176726 day. The amplitude, phase, and mean value of the field vary from year to year presumably due to stellar rotation or dynamo mechanisms.
