Mapa para análise qualitativa de risco por BTEX p ou proximidade com postos de gasolina na cidade de Ensenada, Baja California, México

Due to their carcinogenic properties, exposure to volatile organic compounds such as benzene, toluene and xylene (BTEX) has been associated with an increased risk of developing cancer in people living or working near gas stations. This study puts forward a methodological approach to study the problems posed by VOCs on individuals exposed to hydrocarbons. The data obtained indicate that there is a greater presence of VOCs in the areas close to point sources of emission and, therefore, a greater exposure to toxic factors. This paper presents a simple procedure to establish which areas are vulnerable to technological risks within the urban area owing to the presence of BTEX by using GIS technology, which enables spatial analysis of benzene emissions to the atmosphere. These results will serve the agencies involved in decision-making. There is no clear legislation in Mexico to protect people living in the vicinity of gas stations. Therefore, programs should be developed to reduce their impact on the population at the environmental, health and social levels.La exposición a compuestos orgánicos volátiles (COV) presentes en la gasolina, como el benceno, tolueno, etilbenceno y xileno (BTEX), por su capacidad cancerígena se ha asociado con el aumento del riesgo a desarrollar cáncer en las personas que viven o trabajan en las proximidades de las estaciones de servicio. En este trabajo se propone una aproximación metodológica para estudiar la problemática que representan los COV en los individuos expuestos a los hidrocarburos. Los datos obtenidos indican que existe mayor presencia de COV en las zonas ubicadas en la cercanía de las fuentes puntuales de emisión y por ende con mayor exposición a factores tóxicos. Con este trabajo se plantea un procedimiento sencillo para establecer las zonas vulnerables a riesgos tecnológicos dentro del área urbana por presencia de BTEX, utilizando para ello la tecnología SIG que permite realizar un análisis espacial de las emisiones de benceno a la atmósfera. Estos resultados quedarán al servicio de los organismos involucrados en la toma de decisiones. En México no existe una legislación clara que proteja a los habitantes de las cercanías de las estaciones de servicio, por lo tanto se deben desarrollar programas para disminuir el impacto en la población a nivel ambiental, sanitario y social.A exposição a compostos orgânicos voláteis (COV) presentes na gasolina, como o benzeno, tolueno, etilbenzeno e xileno (BTEX), pela sua ação cancerígena foi associada ao aumento do risco de desenvolver cancro, nas pessoas que vivem ou trabalham nas proximidades das estações de serviço.

Face-based constructive approach in 3D environment to facilitate the interpretation of multiview orthographic projection to future engineers

[EN] One of the main objectives of Engineering Graphics’ syllabusis to improve the capacity of spatial vision of students, as well as providing essential teaching of graphic representation techniques. In this course, students should create and interpret engineering drawings. However, a significant number of them have problems interpreting and understanding multiview orthographic projections. The course is commonly studied at first year of several engineering Bachelor’s Degrees. In this course, the capacity of spatial vision is critical, asstudents have to interpret a real object from different projection methods. Nevertheless, this is not an obvious task for most students, since either they have no prior training or traditionally this training has no effect on student’s capability of reflexion and interpretation. We consider that facilitating the object interpretation may involve a significant educational improvement. For this reason, in this work we present the approach and development of a specific method to interpret an object. It is focused on harnessing the three dimensional (3D) environment of AutoCAD ® software which is used in the course, for the face-based construction of objects.Pérez-Belis, V.; Gracia-Ibáñez, V.; Plumed, R.; Gómez-Fabra, M.; Agost, M.; Piquer, A.; González-Lluch, C....

Rarity of monodominance in hyperdiverse Amazonian forests.

Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence of monodominance in a massive, basin-wide database of forest-inventory plots from the Amazon Tree Diversity Network (ATDN). Utilizing a simple defining metric of at least half of the trees ≥ 10 cm diameter belonging to one species, we found only a few occurrences of monodominance in Amazonia, and the phenomenon was not significantly linked to previously hypothesized life history traits such wood density, seed mass, ectomycorrhizal associations, or Rhizobium nodulation. In our analysis, coppicing (the formation of sprouts at the base of the tree or on roots) was the only trait significantly linked to monodominance. While at specific locales coppicing or ectomycorrhizal associations may confer a considerable advantage to a tree species and lead to its monodominance, very few species have these traits. Mining of the ATDN dataset suggests that monodominance is quite rare in Amazonia, and may be linked primarily to edaphic factors

COVID-19 Severity and Survival over Time in Patients with Hematologic Malignancies: A Population-Based Registry Study

Mortality rates for COVID-19 have declined over time in the general population, but data in patients with hematologic malignancies are contradictory. We identified independent prognostic factors for COVID-19 severity and survival in unvaccinated patients with hematologic malignancies, compared mortality rates over time and versus non-cancer inpatients, and investigated post COVID-19 condition. Data were analyzed from 1166 consecutive, eligible patients with hematologic malignancies from the population-based HEMATO-MADRID registry, Spain, with COVID-19 prior to vaccination roll-out, stratified into early (February–June 2020; n = 769 (66%)) and later (July 2020–February 2021; n = 397 (34%)) cohorts. Propensity-score matched non-cancer patients were identified from the SEMI-COVID registry. A lower proportion of patients were hospitalized in the later waves (54.2%) compared to the earlier (88.6%), OR 0.15, 95%CI 0.11–0.20. The proportion of hospitalized patients admitted to the ICU was higher in the later cohort (103/215, 47.9%) compared with the early cohort (170/681, 25.0%, 2.77; 2.01–3.82). The reduced 30-day mortality between early and later cohorts of non-cancer inpatients (29.6% vs. 12.6%, OR 0.34; 0.22–0.53) was not paralleled in inpatients with hematologic malignancies (32.3% vs. 34.8%, OR 1.12; 0.81–1.5). Among evaluable patients, 27.3% had post COVID-19 condition. These findings will help inform evidence-based preventive and therapeutic strategies for patients with hematologic malignancies and COVID-19 diagnosis.Depto. de MedicinaFac. de MedicinaTRUEFundación Madrileña de Hematología y HemoterapiaFundación Leucemia y LinfomaAsociación Madrileña de Hematología y Hemoterapiapu

Geographic patterns of tree dispersal modes in Amazonia and their ecological correlates

Unidad de excelencia María de Maeztu CEX2019-000940-MAim: To investigate the geographic patterns and ecological correlates in the geographic distribution of the most common tree dispersal modes in Amazonia (endozoochory, synzoochory, anemochory and hydrochory). We examined if the proportional abundance of these dispersal modes could be explained by the availability of dispersal agents (disperser-availability hypothesis) and/or the availability of resources for constructing zoochorous fruits (resource-availability hypothesis). Time period: Tree-inventory plots established between 1934 and 2019. Major taxa studied: Trees with a diameter at breast height (DBH) ≥ 9.55 cm. Location: Amazonia, here defined as the lowland rain forests of the Amazon River basin and the Guiana Shield. Methods: We assigned dispersal modes to a total of 5433 species and morphospecies within 1877 tree-inventory plots across terra-firme, seasonally flooded, and permanently flooded forests. We investigated geographic patterns in the proportional abundance of dispersal modes. We performed an abundance-weighted mean pairwise distance (MPD) test and fit generalized linear models (GLMs) to explain the geographic distribution of dispersal modes. Results: Anemochory was significantly, positively associated with mean annual wind speed, and hydrochory was significantly higher in flooded forests. Dispersal modes did not consistently show significant associations with the availability of resources for constructing zoochorous fruits. A lower dissimilarity in dispersal modes, resulting from a higher dominance of endozoochory, occurred in terra-firme forests (excluding podzols) compared to flooded forests. Main conclusions: The disperser-availability hypothesis was well supported for abiotic dispersal modes (anemochory and hydrochory). The availability of resources for constructing zoochorous fruits seems an unlikely explanation for the distribution of dispersal modes in Amazonia. The association between frugivores and the proportional abundance of zoochory requires further research, as tree recruitment not only depends on dispersal vectors but also on conditions that favour or limit seedling recruitment across forest types

Geography and ecology shape the phylogenetic composition of Amazonian tree communities

AimAmazonia hosts more tree species from numerous evolutionary lineages, both young and ancient, than any other biogeographic region. Previous studies have shown that tree lineages colonized multiple edaphic environments and dispersed widely across Amazonia, leading to a hypothesis, which we test, that lineages should not be strongly associated with either geographic regions or edaphic forest types.LocationAmazonia.TaxonAngiosperms (Magnoliids; Monocots; Eudicots).MethodsData for the abundance of 5082 tree species in 1989 plots were combined with a mega-phylogeny. We applied evolutionary ordination to assess how phylogenetic composition varies across Amazonia. We used variation partitioning and Moran's eigenvector maps (MEM) to test and quantify the separate and joint contributions of spatial and environmental variables to explain the phylogenetic composition of plots. We tested the indicator value of lineages for geographic regions and edaphic forest types and mapped associations onto the phylogeny.ResultsIn the terra firme and várzea forest types, the phylogenetic composition varies by geographic region, but the igapó and white-sand forest types retain a unique evolutionary signature regardless of region. Overall, we find that soil chemistry, climate and topography explain 24% of the variation in phylogenetic composition, with 79% of that variation being spatially structured (R2 = 19% overall for combined spatial/environmental effects). The phylogenetic composition also shows substantial spatial patterns not related to the environmental variables we quantified (R2 = 28%). A greater number of lineages were significant indicators of geographic regions than forest types.Main ConclusionNumerous tree lineages, including some ancient ones (>66 Ma), show strong associations with geographic regions and edaphic forest types of Amazonia. This shows that specialization in specific edaphic environments has played a long-standing role in the evolutionary assembly of Amazonian forests. Furthermore, many lineages, even those that have dispersed across Amazonia, dominate within a specific region, likely because of phylogenetically conserved niches for environmental conditions that are prevalent within regions
