Black carbon and particulate matter concentrations amid central Chile's extreme wildfires.

The increase in the frequency and severity of global wildfires has been largely influenced by climate change and land use changes. From February 2 to 6, 2024, central Chile experienced its most devastating wildland-urban interface wildfire in history, severely impacting the Valparaíso region. This catastrophic event, which led to extensive forest destruction, the loss of thousands of homes, and over a hundred human fatalities, directly impacted the area surrounding the campus of Federico Santa María Technical University. In that period, an air quality monitoring campaign was set up on the campus to measure black carbon (BC) and particulate matter (PM) during the wildfire season. The monitoring station was located directly within the smoke plume, allowing for the collection of unprecedented air quality data. Extremely high concentrations of BC at 880 nm were reported during the wildfires, with a daily mean (±σ) of 14.83 ± 19.52 µg m-3. Peak concentrations measured at 880 nm and 375 nm reached 812.89 µg m-3 and 1561.24 µg m-3, respectively. The maximum daily mean BC concentrations at these wavelengths were 55 and 99 times higher, respectively, compared to the pre-event period. The mean Ångström absorbing coefficient during the event was 1.66, indicating biomass burning as the primary BC source, while the maximum BC/PM2.5 ratio (at 375 nm) reached 57 %. From February 2 to 5, 2024, PM concentrations exceeded the Chilean air quality standard by 82 % and 198 % for coarse and fine particles, respectively. These levels are 4.7 and 6.0 times higher than the World Health Organization's recommendations. These elevated concentrations persisted for up to three days after the fire was extinguished. This study provides unique evidence of the rapid deterioration of regional air quality during a wildfire event using in situ measurements, serving as a stark reminder of the far-reaching consequences of a warming climate.

Implications of fuel poverty for indoor black carbon concentrations from space heating.

Despite the global transition towards cleaner energy sources observed over the last decade, disparities in access persist worldwide. The dependence on biomass for household heating exacerbates fuel poverty, as economically vulnerable households face challenges in obtaining certified firewood and often resort to using contaminated biomass as a substitute, either partially or completely. We examined black carbon (BC) particle concentrations -a marker for combustion- during wood stove operation through a five-day case study in a typical Chilean household. BC increased rapidly following the ignition of the stove, with the combustion of dry Eucalyptus globulus logs yielding a substantially lower peak (5.29 µg/m3) than when using unclean biomass: 35.75 µg/m3 with demolition wood and painted furniture, and 87.11 µg/m3 with the addition of a blend of particleboard with polystyrene foam. During the latter two events, BC particles remained indoors for about 20 h before the concentrations reverted to pre-spike levels. The slow decay in BC concentrations was further influenced by the infiltration of outdoor air. The mean indoor BC concentrations were comparable to or even exceeded those observed on busy roads in major cities worldwide. These results highlight the risks associated with limited access to clean fuels for indoor heating, alongside inadequate insulation. This study sheds light on the problem of fuel poverty and its adverse effects on health and well-being.

Meaningful Work, Happiness at Work, and Turnover Intentions.

It has been documented that there is a positive relationship between a worker's subjective well-being and productivity, and individuals who are happy in their work have a better attitude when performing activities: happier employees are more productive. Turnover intention, on the other hand, may arise from various factors rather than merely the need to increase a salary, as the traditional economic theory states. The fact that the work performed does not contribute to the worker's life purpose, that there might be a bad relationship with colleagues, or else might play a role in the search for a new job. This study aims to show the relevance of meaningful work in happiness at work and turnover intention. Data from 937 professionals, in 2019, in Mexico were analyzed. Regression analyses were used to assess the impact of meaningful work on happiness at work and turnover intention. Results show that meaningful work, feeling appreciated by coworkers, and enjoyment of daily tasks significantly predict happiness at work. A logit model showed that having a job that contributes to people's life purpose, feeling appreciated, and enjoyment of daily tasks reduces turnover intention. The main contribution of the study is to identify the importance of elements of purpose and meaning in the work context, contributing to economic theory. Limitations include the use of single items from a more extensive survey, which might diminish the validity and reliability of the constructs under scrutiny. Future directions point towards the need for more robust indicators of the variables of interest, but the findings emphasize the importance of research focused on the meaning workers attribute to their own work and the effects this attribution might have on their own wellbeing, organizational results, and productivity, including a return of investment (ROI) indicators.

The IWH-BEAT Questionnaire Validation.

Positive Psychology has been devoted to enhancing well-being within organizations during the first two decades of the current millennium. Unfortunately, little data is available on current assessment related to positive psychology practices in the workplace. Therefore, to assess organizational well-being in a valid and reliable way, a new scale has been created and validated by the Institute for Wellbeing and Happiness at Tecmilenio University in Mexico: the BEAT Questionnaire whose main contribution to previous models is the element of meaningful work. EFA and CFA were carried out to determine and confirm the scale's structure; internal consistency tests were performed too; additionally, convergence with measures of engagement, labor resources, and worker relations were also confirmed, and discriminant validity was tested by comparing associations with job search intentions and negative relationships in the workplace, yielding an instrument with four clearly defined latent dimensions, composed by 24 highly consistent items, convergent with three other valid and reliable scales. All procedures complied with statistical requirements, delivering a valid and reliable instrument for measuring well-being in the workplace.

Leaf Thermal and Chemical Properties as Natural Drivers of Plant Flammability of Native and Exotic Tree Species of the Valparaíso Region, Chile.

Forest fires are one of the main environmental threats in Chile. Fires in this Mediterranean climate region frequently affect native forests and exotic plantations, including in several cases urban and rural settlements. Considering the scarcity of information regarding the fire response dynamics of tree species that are frequently affected by fires, this study aims to establish a flammability classification according to the evolution of the fire initiation risk presented by the most affected forest species in the Valparaíso region. Three exotic species, Eucalyptus globulus, Pinus radiata, and Acacia dealbata, and two native species, Cryptocarya alba and Quillaja saponaria, were studied. Flammability assays indicate that E. globulus, A. dealbata, and C. alba are extremely flammable, whereas P. radiata and Q. saponaria are flammable. Furthermore, E. globulus and A. dealbata have the highest heating values while Q. saponaria has the lowest values. The extreme flammability of E. globulus, A. dealbata, and C. alba indicates a high susceptibility to ignite. Furthermore, the high heat of combustion of E. globulus and A. dealbata can be associated with a high energy release, increasing the risk of fires spreading. In contrast, Q. saponaria has the lowest predisposition to ignite and capacity to release heat. Accordingly, this work shows that all studied tree species contain organic metabolites that are potentially flammable (sesquiterpenes, aliphatic hydrocarbons, alcohol esters, ketones, diterpenes, and triterpenes) and can be considered as drivers of flammability in vegetation. Finally, these preliminary results will aid in the construction of more resilient landscapes in the near future.

The Model of the Extraction Process of Rare Metals Under Condition of Filtration Combustion Wave.

To study the mass transfer of metal compounds, a model of filtration combustion of metal-containing combustible mixtures is developed. Using cadmium-containing mixture as an example, the main characteristics of filtration combustion are determined when the gas pressure at the reactor inlet is constant. It is shown that under the conditions of a filtration combustion wave, a metal can evaporate into the gas phase and be transferred with gas through the reactor. Due to the evaporation and condensation of cadmium, it is transported and accumulated before the combustion front. The possibility of controlling the mass transfer of metal compounds under the conditions of a filtration combustion wave with the aim of concentrating them is shown. It is revealed that a 4-fold increase in the pressure difference at the open boundaries of the reactor can lead to a decrease in the maximum metal concentration by about 1.5 times. An increase in the concentration of metals due to mass transfer will subsequently make it economically feasible to extract them by traditional methods.

Conocimiento y prácticas relacionadas con control y prevención de COVID-19 en trabajadores de la salud / Knowledge and practice regarding COVID-19 infection, control and prevention among healthcare workers

La enfermedad por coronavirus 2019 (COVID-19) ha afectado a los trabajadores de la salud (TS) quienes suman riesgo de exposición en la comunidad y el trabajo. El conocimiento y preparación son fundamentales, sin embargo, durante la pandemia se han suspendido las actividades presenciales de formación-capacitación. El objetivo de este estudio fue determinar si la educación en línea genera una diferencia en el conocimiento y práctica de prevención y control de infecciones (PCI) para la COVID-19 en TS. Previo consentimiento, se administró un cuestionario antes-después a los participantes de un curso de PCI en línea. Para la evaluación de conocimientos y prácticas se diseñaron preguntas tipo Likert con valores de 1 a 5, realizando el análisis con la prueba no paramétrica de rangos con signo de Wilcoxon para muestras relacionadas. En 345 participantes, la mediana fue 30 (RIC 15) años, femenino (224, 65%), residentes en el departamento de Guatemala (221, 57%), labora en sector público (155, 44.9%), sector privado (154, 44.6%), y seguro social (29, 8.4%). La evaluación antes-después mostró diferencia significativa de la brecha existente en el conocimiento y las prácticas de PCI (p < .05). La mayor brecha se observó en el autocuidado de la salud física, mental y nutricional. En las percepciones, uno de cada tres encuestados manifestó temor a sufrir estigma en caso de resultar infectados. La educación y entrenamiento en PCI es esencial ante una enfermedad altamente contagiosa que amenaza la salud y seguridad de los TS, principalmente en entornos sanitarios con recursos limitados.

The coronavirus disease 2019 (COVID-19) has affected health workers (HCWs) who adds risk of exposure in the community and at work. Knowledge and preparation are essential. However, during the pandemic, face-to-face training activities have been suspended. The objective of this study was to determine if online education generate a difference in the knowledge and practice of infection prevention and control (IPC) of COVID-19 in HCWs. With prior consent, a before-after questionnaire was administered to participants of an online PCI course. For the evaluation of knowledge and practices, Likert-type questions were designed with values from 1 to 5, performing the analysis with the non-parametric test of Wilcoxon signed ranges for related samples. In 345 participants, the median was 30 (IQR 15) years, female (224, 65%), living in the department of Guatemala (221, 57%), working in the public sector (155, 44.9%), private sector (154, 44.6%), and social security (29, 8.4%). The before-after assessment showed a significant difference in the gap between knowledge and practices. The largest gap was observed in self-care of physical, mental, and nutritional health. About perceptions, one out of every three respondents expressed fear of suffering stigma if they get infected. Education and training in IPC are essential in the face of a highly contagious disease that threatens the health and safety of HCWs, mainly in healthcare settings with limited resources.

Manifestaciones clínicas y complicaciones de la Enfermedad por Coronavirus 2019 (COVID-19): revisión de la literatura / Clinical manifestations and complications of Coronavirus Disease 2019 (COVID-19)

La Enfermedad por Coronavirus 2019 (COVID-19) supone un reto sin precedentes para la salud pública. Los médicos deben fortalecer sus habilidades clínicas para combatir esta nueva enfermedad. El objetivo de esta revisión fue describir los signos, síntomas y complicaciones de pacientes con COVID-19. Se realizó una búsqueda en la literatura en la base de datos PubMed incluyendo publicaciones entre 1 de diciembre 2019 y 15 de agosto 2020, sin restricciones de lenguaje, utilizando las palabras clave 'COVID-19' cruzada con 'manifestaciones clínicas', 'signos y síntomas' y 'complicaciones'. Se incluyeron revisiones sistemáticas y meta-análisis, estudios epidemiológicos y series de casos. Se identificaron 1,066 artículos, de los cuales se seleccionaron 71 de acuerdo a los contenidos previamente definidos por los autores. La COVID-19 presenta un curso de leve a moderado y severo-crítico, específicamente en mayores de 65 años con o sin comorbilidades. Los signos y síntomas no son específicos y usualmente se superponen de acuerdo a la edad y a la fase de la enfermedad. Los síntomas más comunes son fiebre, tos y fatiga. Síntomas menos comunes incluyen escalofríos, dolor de garganta, cefalea, mialgias/artralgias, pérdida del gusto y del olfato, diarrea, nausea, vómitos, congestión nasal, palpitaciones, opresión precordial y dolor pleurítico. La sintomatología en niños difiere de la de los adultos y el curso es usualmente benigno y de baja mortalidad. La evaluación clínica de COVID-19 supone un reto hoy en día. Sin embargo, el conocimiento de la historia natural de la enfermedad permite situar los síntomas comunes e inespecíficos en el contexto clínico correcto.

Coronavirus disease 2019 (COVID-19) presents an unprecedented challenge to public health. Physicians must strengthen clinical skills for this new disease. This review aimed to describe the signs, symptoms and complications of patients with COVID-19. A literature search was conducted in the PubMed database, including publications between December 1, 2019, to August 15, 2020, without language restrictions, using the keywords 'COVID-19' crossed with 'clinical manifestations', 'signs and symptoms', and 'complications'. Systematic reviews, meta-analysis, epidemiological studies, and case report series were included. A total of 1,066 articles were identi¬fied, among 71 were selected according to the contents previously defined by the authors. COVID-19 has a mild to moderate or severe-critical course, specifically in over 65 years of age, with or without comorbidities. Signs and symptoms are not specific and usually overlap according to the age and stage of the disease. The most common symptoms are fever, cough, and fatigue. Less common symptoms include chills, sore throat, headache, myalgia/ arthralgia, loss of taste and smell, diarrhea, nausea, vomiting, nasal congestion, palpitations, chest tightness, and pleuritic pain. The symptomatology in children differs from that of adults, and the course is usually benign and low mortality. Clinical evaluation of COVID-19 is challenging today. However, knowledge of the disease's natural history allows placing common and nonspecific symptoms in the correct clinical context.

Syngas Production From the Reforming of Typical Biogas Compositions in an Inert Porous Media Reactor.

Syngas production by inert porous media combustion of rich biogas-air mixtures was studied experimentally, focusing on carbon dioxide utilization and process efficiency. Different gas mixtures of natural gas and carbon dioxide, which simulated a typical biogas composition of 100:0, 70:30, 55:45, and 40:60 (CH4:CO2), were comparatively analyzed considering combustion waves temperatures and velocities, and chemical concentrations products, at high equivalence ratios of φ = 1.5 and φ = 2.0. Different CO2 concentrations on biogas composition showed higher H2 productions than on pure methane (100:0), mainly due to CO2 reforming reactions. Also, syngas production, hydrogen yields, and process efficiency by means of biogas filtration combustion were higher than under methane filtration combustion. Results of the thermochemical conversion of biogas show an alternative and promising non-catalytic technique to CO2 utilization.

Fly ash as stimulant for anaerobic digestion: effect over hydrolytic stage and methane generation rate.

Thermoelectric fly ash was used as a micronutrient source for microorganisms in the anaerobic digestion process of thermally pretreated (1 hour, 120 °C) secondary sludge. The obtained results not only suggest that fly ash improves methane generation in the conversion of volatile fatty acids into methane, but also show a new observation, that the fly ash contributes in the particulate organic solubilization. The maximum methane production rate increased from 6.52 mL/L/d to 22.59 mL/L/d when fly ash was added at a dosage of 150 mg/L in biochemical methane potential tests compared with tests with no added ash. Additionally, the kinetic constants of the hydrolysis of particulate organic matter were obtained in both cases (with and without added ash) in batch reactors using a first-order kinetic model; in the case of no addition, the first-order kinetic parameter was 0.019 ± 0.002 d-1, while with ashes this value increased to 0.045 ± 0.000 d-1. Therefore, the addition of fly ash improves methane generation and hydrolytic kinetics in different orders of magnitude.

Emission factors for PM2.5, CO, CO2, NOx, SO2 and particle size distributions from the combustion of wood species using a new controlled combustion chamber 3CE.

The objective of this research was to determine emission factors (EF) for particulate matter (PM2.5), combustion gases and particle size distribution generated by the combustion of Eucalyptus globulus (EG), Nothofagus obliqua (NO), both hardwoods, and Pinus radiata (PR), softwood, using a controlled combustion chamber (3CE). Additionally, the contribution of the different emissions stages associated with the combustion of these wood samples was also determined. Combustion experiments were performed using shaving size dried wood (0% humidity). The emission samples were collected with a tedlar bag and sampling cartridges containing quartz fiber filters. High reproducibility was achieved between experiment repetitions (CV<10%, n=3). The EF for PM2.5 was 1.06gkg-1 for EG, 1.33gkg-1 for NO, and 0.84gkg-1 for PR. Using a laser aerosol spectrometer (0.25-34µm), the contribution of particle emissions (PM2.5) in each stage of emission process (SEP) was sampled in real time. Particle size of 0.265µm were predominant during all stages, and the percentages emitted were PR (33%), EG (29%), and NO (21%). The distributions of EF for PM2.5 in pre-ignition, flame and smoldering stage varied from predominance of the flame stage for PR (77%) to predominance of the smoldering stage for NO (60%). These results prove that flame phase is not the only stage contributing to emissions and on the contrary, pre-ignition and in especial post-combustion smoldering have also very significant contributions. This demonstrates that particle concentrations measured only in stationary state during flame stage may cause underestimation of emissions.

Description of Laccomimus gen. n. and eleven new species from the Neotropical region (Coleoptera, Dytiscidae, Laccophilinae).

A new genus of laccophiline diving beetles, Laccomimus gen. n., is here described on the basis of a large number of specimens from various collections formerly misidentified as members of the Neotropical genus Laccodytes Régimbart, 1895. Except for similar size, however, the new genus is not closely related to Laccodytes. Instead, it seems to be sister to the Oriental genus Laccosternus Brancucci, 1983, both sharing a similar body size and shape, characters of the female genital structures, and shape of the prosternal process. Twelve species are recognised within Laccomimus, all new to science except Laccomimus pumilio (LeConte, 1878) comb. n., the type species. The new species are: Laccomimus alvarengi sp. n., L. amazonas sp. n., L. bolivari sp. n., L. bordoni sp. n., L. distinctus sp. n., L. improvidus sp. n., L. malkini sp. n., L. spangleri sp. n., L. spinosus sp. n., L. variegatus sp. n., L. youngi sp. n. The distribution of the new genus includes most of the Neotropics, with one species, L. pumilio, reaching Florida, USA. Each taxon is described and illustrated and a key for their identification is provided. Laccomimus is a widespread and relatively common genus in tropical America, the species of which have a wide distributional range, except for a few confined to more restricted areas. In spite of this, Laccomimus is a very uniform genus in body shape, size and colouration, and in most cases identification of the species is possible only after examination of the male genitalia. A key to distinguish genera of the tribe Laccophilini is also presented.

Revision of the Neotropical burrowing water beetle genus Liocanthydrus Guignot (Coleoptera: Noteridae: Noterinae: Noterini) with the description of two new species.

The burrowing water beetle genus Liocanthydrus Guignot, 1957 is redefined and its species are revised. Of the four current species, three are recognized as belonging to the genus and redescribed: L. angustus (Guignot, 1957), L. octoguttatus (Zimmermann, 1921) and L. uniformis (Zimmermann, 1921). The fourth species, L. buqueti (Laporte, 1835) is found to not be a member of Liocanthydrus, but of an undescribed genus. The noterid genus Siolius J. Balfour-Browne, 1969, is synonymized with Liocanthydrus (new synonymy) based on comparison of type specimens in both groups. Two of the three species described in Siolius, S. bicolor J. Balfour-Browne, 1969 and S. clayae J. Balfour-Browne, 1969, are recognized as valid, transferred to Liocanthydrus, and redescribed. The third, S. amazonicus J. Balfour- Browne, 1969, is synonymized with L. uniformis (new synonymy). Two new species from South America, L. armulatus sp. n. and L. nanops sp. n. are also recognized and described. A lectotype is designated for Canthydrus octoguttatus Zimmermann, 1921. After this revision, there are seven valid species of Liocanthydrus. Habitus photos are provided, diagnostic characters of all recognized species are illustrated, distributions are provided, and a key to the species is included.

Introducción.- Si bien los parámetros antropométricos (peso, talla y perímetros cefálico) usados en la evaluación nutricional del recien nacido (RN) pueden ser normales, algunos RN a término (RNT) adecuados para su edad gestacional (AEG) sufren de desnutrición fetal cuando se valoran los comportamientos graso y proteico a través del test de Metcoff. El objetivo del presente trabajo es conocer la incidencia de desnutrición fetal en los RNT AEG, mediante la evaluación clínica del estado nutricional (ECEN) y su calificación según Metcoff, además de conocer las características de sus madres, en el periodo de marzo del 2000 a noviembre del 2001 en el Instituto Materno Perintal (IMP) de Lima. Métodos: Se realizó un estudio descriptivo, transversal y prospectivo en el IMP. Se evaluó el estado nutricional de una muestra de 56 RNT AEG, vivos, de parto eutócico y único, sin la presencia de factores de riesgo que afecten la salud de la madre, el RN o de ambos. La selección fue de una muestra probabilística de tipo accidental. Los resultados se muestran en tablas y gráficos. Resultados: Se evaluaron 56 RNT AEG. Predominó el sexo femenino (55.4 por ciento) con respecto al masculino (44.6 por ciento). El promedio y desviación estándar del peso, talla y perímetro cefálico para los considerados como bien nutridos fue 3347 ± 290 g, 50.22 ± 1.17 cm y 34.29 ±1.09 cm, respectivamente, mientras que para los desnutridos fue 3068 ± 139 g, 49.6 ± 0.55 cm y 33.4 ± 1.51 cm, respectivamente. El test de Metcoff mostró desnutrición clínica en 5 RNT AEG, lo que representa una incidencia del 8.9 por ciento.

Saúde, ambiente, desenvolvimento e ecossistemas: um levantamento da produção na pós-graduação da ENSP/FIOCRUZ na década de 1990 / Health, environment, development and ecosystems: a survey of the production in the after-graduation of the ENSP/FIOCRUZ in the decade of 1990

O presente estudo teve como objetivo levantar e analisar a interface Saúde e Ambiente no campo da Saúde Pública, tendo como material empírico a produção acadêmica - dissertações de mestrado e teses de doutorado - da Pós Graduação em Saúde Pública da ENSP/FIOCRUZ, defendidas na década de noventa do século XX. A hipótese formulada foi a de que o crescimento do debate relacionado à questão ambiental, a partir da década de 70, teria propiciado, na década de noventa, sob os auspícios da Eco - 92, abordagens ecossistêmicas aos temas ambientais, no campo da Saúde Pública. A metodologia baseou-se no estudo sistemático desta produção, para identificar a interface Saúde e Ambiente, e pontuar as tendências que as próprias pesquisas apontam. O levantamento dos trabalhos foi feito através de palavras-chaves. Na pesquisa destes estudos, anotou-se as citações em que as palavras - ôsaúdeö, ôambienteö, ôdesenvolvimentoö, e ôecossistemasö, surgem, possibilitando a análise de tendências de abordagem dos temas através do seu ôcontexto de usoö. Foram selecionadas, 20 dissertações e 3 teses, o que permitiu concluir que a interface Saúde e Ambiente, esteve presente nos programas de pós-graduação em Saúde Pública, da instituição no período. Foi identificada, com apenas uma exceção, a configuração de quatro áreas temáticas. Os contextos de uso de ôsaúdeö, revelaram cinco tendências. Em relação ao ôdesenvolvimentoö, dos 23 trabalhos selecionados, 17 abordaram a questão do desenvolvimento em sua discussão, e encontramos sete formas de utilização da noção de ôdesenvolvimentoö. Concluiu-se que a produção da interface Saúde/Ambiente considerou o desenvolvimento como condição associada às questões de saúde pública. Nas questões relacionadas ao ôambienteö, nossa pesquisa apontou para uma tendência dos autores abordá-lo de forma associada às temáticas de suas pesquisas. Com relação ao ôecossistema(s)ö consideramos, que embora seis autores não o tenham referido em seus trabalhos, dezessete o fizeram pelo menos uma vez, o que possivelmente aponta para um consenso relacionado ao conceito de ecossistema na interface saúde e ambiente. Em cinco dos trabalhos, os contextos de uso do termo, apontaram para uma tendência de abordar a questão do meio ambiente no campo da saúde pública através da noção de ecossistemas, o que confirmaria a hipótese proposta para este estudo.
