    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.scitotenv.2013.03.097 Byline: Elisa Venturini, Ivano Vassura, Laura Ferroni, Simona Raffo, Fabrizio Passarini, David C.S. Beddows, Roy M. Harrison Abstract: In order to assess the contribution of a Municipal Solid Waste incinerator to the area's total contamination, metals and soluble ions have been determined in bulk deposition collected at sites affected by different levels of plant emissions, according to the results of the Calpuff air dispersion model. Results show that in general fluxes monitored at the different sites during the same period are quite similar for each analyte. Deposition fluxes of nitrite and ammonium are significantly lower at the more distant site, while copper is significantly higher at this site, possibly because of copper fungicide used on the nearby agriculture land. The presence of sea spray and resuspended soil dust can be inferred from Pearson correlation coefficients, while enrichment factors indicate that Cu, Pb and Zn have a probable anthropogenic origin. A more complete evaluation of the sources affecting the area was obtained with PMF analysis. The sources associated with each factor were identified from the source profile and temporal trends. Six factors were identified, three sources associate with natural matrices, while three factors represent anthropogenic sources. The greatest contribution of heavy metals, the most toxic and persistent components determined, is associated with resuspended soil dust, especially when weighted according to their toxicity. The anthropogenic source contribution is similar at all sites, and therefore the incinerator's relative contribution to the total pollutant load appears to be negligible compared to other sources affecting the area.

    Description: Somatic mosaicism in the human brain may alter function of individual neurons. We analyzed genomes of single cells from the forebrains of three human fetuses (15 to 21 weeks postconception) using clonal cell populations. We detected 200 to 400 single-nucleotide variations (SNVs) per cell. SNV patterns resembled those found in cancer cell genomes, indicating a role of background mutagenesis in cancer. SNVs with a frequency of 〉2% in brain were also present in the spleen, revealing a pregastrulation origin. We reconstructed cell lineages for the first five postzygotic cleavages and calculated a mutation rate of ~1.3 mutations per division per cell. Later in development, during neurogenesis, the mutation spectrum shifted toward oxidative damage, and the mutation rate increased. Both neurogenesis and early embryogenesis exhibit substantially more mutagenesis than adulthood.

    Description: Gynecological pelvic cancer is a disease located in the internal genital organs of certain females having undergone hysterectomy. It is thus a castration for these women in the reality of their suffering bodies. Cancer and its treatments are a sum of bodily effractions which reiterate a psychic representation of penetration likened to the passive acceptance of the other into the self. This idea of the foreigner inside of the self brings fantasies, affects and penetrating representations into play which damage the body image, generate images of passivity and revive experiences of «?passivation?». Moreover, this 'breaking and entering' specifically acts on the intimate region of sex, where a woman's and a mother's destiny are incarnated, calling into consciousness the feminine of the woman in its plural forms but also in its relations with sexuality.

    Description: To link to full-text access for this article, visit this link: http://dx.doi.org/10.1016/j.energy.2015.05.105 Byline: Elisa Venturini, Ivano Vassura, Cristian Zanetti, Andrea Pizzi, Giuseppe Toscano, Fabrizio Passarini Abstract: In order to evaluate non-steady phase contribution to the total emissions of a pellet stove in real domestic operations, particulate matter and gaseous emissions were determined separately for different operating conditions, i.e. ignition, partial load, increase in power and nominal load. TSP (Total suspended particulate) was sampled with a dilution system and characterized for TC (total carbon), PAHs (polycyclic aromatic hydrocarbons), the main soluble ions, Ni, As, Cd and Pb. Gas monitoring shows that CO and NO emission factors in ignition phase markedly differ from other operating conditions: NO emission factor is lower, while CO one is much higher, since it is a product of incomplete combustion. Start-up phase emission factors are also higher for TSP, Cd and other products of incomplete combustion, i.e. TC and PAHs. Despite being a non-steady phase, the increase in power phase emission factors appreciably differ from steady state ones only for PAHs. Moreover, the PAHs emitted in non-steady state phases have a higher toxicological burden. In conclusion, in order to evaluate the real impact of pellet stove on the environment, transient conditions should be taken into account. The ignition phase, even though it lasts only 20 min, can significantly contribute to pollutant emission.

    Description: In order to determine the pollution sources in a suburban area and identify the main direction of their origin, PM 2.5 was collected with samplers coupled with a wind select sensor and then subjected to Positive Matrix Factorization (PMF) analysis. In each sample, soluble ions, organic carbon, elemental carbon, levoglucosan, metals, and Polycyclic Aromatic Hydrocarbons (PAHs) were determined. PMF results identified six main sources affecting the area: natural gas home appliances, motor vehicles, regional transport, biomass combustion, manufacturing activities, and secondary aerosol. The connection of factor temporal trends with other parameters (i.e., temperature, PM 2.5 concentration, and photochemical processes) confirms factor attributions. PMF analysis indicated that the main source of PM 2.5 in the area is secondary aerosol. This should be mainly due to regional contributions, owing to both the secondary nature of the source itself and the higher concentration registered in inland air masses. The motor vehicle emission source contribution is also important. This source likely has a prevalent local origin. The most toxic determined components, i.e., PAHs, Cd, Pb, and Ni, are mainly due to vehicular traffic. Even if this is not the main source in the study area, it is the one of greatest concern. The application of PMF analysis to PM 2.5 collected with this new sampling technique made it possible to obtain more detailed results on the sources affecting the area compared to a classical PMF analysis.

    Description: This study aims to characterize PM from the open burning of bonfires as well as detect a series of useful tracer species for source apportionment studies. Total suspended particulate (TSP), PM and PM were collected before, during, and after St. Joseph's Eve (18th of March). On this day, several bonfires are lit throughout the study area. Levoglucosan (Lvg), OC, EC, PAHs, soluble ions, and some metals (Al, Cd, Cu, Ni, and Pb) have been determined in each fraction. Results show that the contamination of the area is similar to what is generally found in suburban areas. The fine fraction makes the highest contribution to PM. This fraction is mainly related to compounds composing the PM secondarily formed, while the coarser fractions are associated with natural matrices. The bonfire event is an important source of particulate. All the combustion markers determined in PM (EC, OC, PAHs (except for Flu and Pyr), K , Cl , and Lvg) register a higher concentration. Lvg/OC ratio confirms higher wood smoke emissions during these days. Both the concentration and the compound profile indicate a different origin of PAHs in the atmosphere. The highest concentration of K and OC in TSP confirm the contribution of open fire, as well, to this fraction, which can be ascribable mainly to combustion ash. Nitrates and sulphates also show a higher concentration in the PM -TSP fraction. Surprisingly, there is also an increase in the concentration of components not usually considered combustion markers, i.e. Pb and Al in PM . This is probably ascribable to their bioaccumulation. In conclusion, Lvg, OC, PAHs, Al, and Pb can be used together as specific markers of bonfires to identify this source of particulate matter.

    Description: À partir du matériel issu d’une recherche sur le cancer gynécologique, les auteurs proposent de comparer deux passations du Thematic Apperception Test, entourant l’événement majeur et actuel de la réalité externe que représente le passage aux traitements de la maladie grave. Les épreuves projectives apprécient l’armature immuable de la structure psychique et sont également sensibles aux aspects actuels de ce que vit le patient. Elles déterminent le poids de l’événement, c’est-à-dire l’effraction de la réalité externe sur le fonctionnement psychique du sujet. Ainsi, partant de la distinction acquise entre l’invariabilité de l’organisation et les mouvements inhérents aux retentissements d’un événement actuel sur l’organisation psychosomatique, l’analyse clinique et projective appréciera les modalités de traitement de l’événement actuel en termes d’aménagements défensifs, d’évolution des représentations et de la progression des affects. L’étude met spécifiquement au jour le repérage des identifications féminines et l’apparition de modalités limites de fonctionnement pour traiter l’angoisse. The material of research on gynecological cancer allows authors to compare two sessions of the Thematic Apperception Test. They surround the major and current event of external reality that are treatments for serious disease. Projective tests show the immutable structure of psychic functioning and are also sensitive to current aspects of what lives the patient. They determine the importance of the event, i.e. the break of psychic functioning of the subject by the external reality. Thus, starting from this distinction, the clinical analysis and projective appreciate the treatment modalities of the current event in terms of defensive arrangements, evolution of representations and progression affects. The study shows specifically female identifications and occurrence borders modalities to treat anxiety.
