Published: April 2023

Embora o currículo da Educação Física nas escolas inclua as lutas, elas continuam recebendo pouca importância. Este estudo buscou identificar a realidade atual da aplicação das lutas na Educação Física escolar, em Barra do Garças-MT, trazendo uma comparação com o município do Rio de Janeiro-RJ. Trata-se de um estudo primário observacional e transversal com duas formas de observação, descritiva e comparativa, utilizando questionário adaptado previamente aplicado e validado na cidade do Rio de Janeiro–RJ, composto por 9 questões fechadas. Foram entrevistados 12 profissionais de Educação Física (4 mulheres e 8 homens) de escolas públicas de Barra do Garças-MT. O presente estudo apresenta resultados que sugerem que a não inclusão desses conteúdos não se deve ao desinteresse dos profissionais ou alunos, mas sim, à formação acadêmica insuficiente. As lutas devem ter a mesma importância que outros conteúdos do currículo do curso de Educação Física, sendo estimulada a inclusão desse conteúdo.

An integrated approach for biofuel and fertilizer production using microalgae grown in wastewater
Authors:   , Musetsho Pfano
Published: April 2023

Microalgae are recognized as potential candidates for resource recovery from wastewater and are projected for biorefinery models. Therefore, this study was undertaken to evaluate the potential of poultry litter and municipal wastewater as nutrient and water sources, for the cultivation of Acutodesmus obliquus for lipids production for biodiesel application. The efficacy of lipid extracted biomass (LEA) as fertilizer for mung bean crops was also assessed in microcosm. A. obliquus cultivation in acid pre-treated poultry litter extract (PPLE) showed maximum biomass production of 1.90 g L-1 , which was 74.67% and 12.61% higher than the raw poultry litter extract (RPPE) and BG11 respectively. Higher NO3-N, NH3-N, and PO4-P removal of 79.51%, 81.82%, and 80.52% respectively were observed in PPLE as compared to RPLE treatment. The highest biomass (140.36 mg L-1 d -1 ), lipids (38.49 mg L-1 d -1 ), and carbohydrates (49.55 mg L-1 d -1 ) productivities were observed in the PPLE medium. The application of LEA as a fertilizer for mung bean crops showed improvement in plant growth and soil microbial activity. A maximum increase in organic carbon (59.5%) and dehydrogenase activity (130.8%) was observed in LEA amended soil which was significantly higher than chemical fertilizer (CF) control in 30 days. Whilst plant fresh weight and leaf chlorophyll in the LEA amended soil was comparable to whole algal biomass (WA) and CF control. The findings of the present study could be a basis for sustainable biorefinery for the valorization of wastewater for the production of microalgae-derived biofuel and byproducts for agricultural applications.
Geografías del amor, el poder y las miserias
Authors: Bozzano Horacio
Published: April 2023

Este libro da cuenta de cómo el libre albedrío, la ignorancia y la manipulación producen dos senderos opuestos entre los seres humanos: el germen de una revolución del amor en unidad planetaria-humanitaria y un camino simultáneo de los seres miserables. Con pocos verbos –aprender a conocer, a sentipensar, a convivir y a transformar– interpretados científicamente mediante cuatro hipótesis, las Geografías del Amor, el Poder y las Miserias fueron escritas para despertar, activar o motivar una revolución del amor, sin que nadie se sienta obligado a aplicar este texto como una receta. Es una invitación a que cada sujeto decida elegir hacer lo mejor de sí mismo, por y para todos, porque estamos en el mismo barco, un efímero, frágil y casi imperceptible botecito en el mar del universo.

Como mínimo, según Yuval Noah Harari, los humanos hemos atravesado tres revoluciones: del conocimiento hace 70 mil años, agrícola hace unos 12 mil y científica hace 5 siglos. Anárquica y aparentemente desordenada está naciendo una revolución del amor. Estos tiempos de pandemia son una gran oportunidad para producir profundas transformaciones. También son tiempos de exacerbaciones en amores, poderes y miserias, donde los amorosos parecieran volverse más amorosos, los miserables más miserables y los más poderosos, amorosos o miserables, según le quepa el sayo a cada uno. Siempre existieron y seguirán existiendo miserables: es una constante. También el amor es una constante, pero es necesaria una revolución por el buen vivir de toda la Humanidad. Este libro es una invitación a construir juntos en los próximos años dos utopías reales con ciudadanos de todas las tribus urbanas y rurales de los casi 200 países del mundo, para elegir los territorios posibles a los imposibles antes que sea tarde.

Aerosol deposition to the boreal forest in the vicinity of the Alberta Oil Sands
Authors: Jiang Timothy , Gordon Mark , Makar Paul A. , Staebler Ralf M. , Wheeler Michael
Published: April 2023

Abstract. Measurements of size-resolved aerosol concentration and
fluxes were made in a forest in the Athabasca Oil Sands Region (AOSR) of
Alberta, Canada, in August 2021 with the aim of investigating (a) particle
size distributions from different sources, (b) size-resolved particle
deposition velocities, and (c) the rate of vertical mixing in the canopy.
Particle size distributions were attributed to different sources determined
by wind direction. Air mixed with smokestack plumes from oil sands
processing facilities had higher number concentrations with peak number at
diameters near 70 nm. Aerosols from the direction of open-pit mine faces
showed number concentration peaks near 150 nm and volume distribution peaks
near 250 nm (with secondary peaks near 600 nm). Size-resolved deposition
fluxes were calculated which show good agreement with previous measurements
and a recent parameterization. There is a minimum deposition velocity of
vd=0.02 cm s−1 for particles of 80 nm diameter; however, there is
a large amount of variation in the measurements, and this value is not
significantly different from zero in the 68 % confidence interval.
Finally, gradient measurements of aerosol particles (with diameters
<1 µm) demonstrated nighttime decoupling of air within and
above the forest canopy, with median lag times at night of up to 40 min and
lag times between 2 and 5 min during the day. Aerosol mass fluxes (diameters <1 µm) determined using flux–gradient methods (with
different diffusion parameterizations) underestimate the flux magnitude
relative to eddy covariance flux measurements when averaged over the nearly
1-month measurement period. However, there is significant uncertainty in the
averages determined using the flux–gradient method.

Abstract. Land–atmosphere interactions govern the process of dust emission and transport. An accurate depiction of these physical processes within numerical weather prediction models allows for better estimating the spatial and temporal distribution of the dust burden and the characterisation of source and recipient areas. In the presented study, the ECMWF-IFS (European Centre for Medium-Range Weather Forecast – Integrated Forecasting System) outputs, produced with and without the assimilation of Aeolus quality-assured Rayleigh–clear and Mie–cloudy horizontal line-of-sight wind profiles, are used as initial or boundary conditions in the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) to simulate 2-month periods in the spring and autumn of 2020, focusing on a case study in October. The experiments have been performed over the broader eastern Mediterranean and Middle East (EMME) region, which is frequently subjected to dust transport, as it encompasses some of the most active erodible dust sources. Aerosol- and dust-related model outputs (extinction coefficient, optical depth and concentrations) are qualitatively and quantitatively evaluated against ground- and satellite-based observations. Ground-based columnar and vertically resolved aerosol optical properties are acquired through AERONET sun photometers and PollyXT lidar, while near-surface concentrations are taken from EMEP. Satellite-derived vertical dust and columnar aerosol optical properties are acquired through LIVAS (LIdar climatology of Vertical Aerosol Structure) and MIDAS (ModIs Dust AeroSol), respectively. Overall, in cases of either high or low aerosol loadings, the model predictive skill is improved when WRF-Chem simulations are initialised with the meteorological fields of Aeolus wind profiles assimilated by the IFS. The improvement varies in space and time, with the most significant impact observed during the autumn months in the study region. Comparison with observation datasets saw a remarkable improvement in columnar aerosol optical depths, vertically resolved dust mass concentrations and near-surface particulate concentrations in the assimilated run against the control run. Reductions in model biases, either positive or negative, and an increase in the correlation between simulated and observed values was achieved for October 2020.
POLIPHON conversion factors for retrieving dust-related cloud condensation nuclei and ice-nucleating particle concentration profiles at oceanic sites

Published: April 2023

Abstract. Aerosol–cloud interactions (ACIs) are the largest contributor to
the uncertainty in the global radiation budget. To improve the current
consideration of ACIs in global circulation models, it is necessary to
characterize the 3-D distribution of dust-related cloud condensation nuclei
concentration (CCNC) and ice-nucleating particle concentration (INPC)
globally. This can potentially be realized using the POlarization
LIdar PHOtometer Networking (POLIPHON) method together with spaceborne lidar
observations. However, dust-related conversion factors that convert bulk
aerosol optical properties from lidar measurements to aerosol microphysical
properties are still less constrained in many regions, which limits the
applications of the POLIPHON method. Here we retrieve the essential
dust-related conversion factors at remote oceanic and coastal sites using the
historical AErosol RObotic NETwork (AERONET) database.
Depolarization-ratio-based dust ratios Rd at 1020 nm are
applied to identify the dust-occurring cases, thus enabling us to contain
fine-mode dust-dominated cases (after the preferential removal of large-sized dust particles during transport), study the evolution of dust microphysical properties along the transoceanic pathway, and mitigate occasional interference of large-sized marine aerosols. The newly proposed scheme is proven to be valid and feasible by intercomparisons with previous studies at
nine sites in/near deserts. The dust-related conversion factors are
calculated at 20 oceanic and coastal sites using both pure dust (PD) and PD plus dust-dominated mixture (PD+DDM)
datasets. At nearly half of the sites, the
conversion factors are solely calculated using the PD datasets, while at the remaining sites, the participation of DDM datasets is required to ensure a sufficient number of data for the calculation. Evident variation trends in conversion factors are found for cv,d (extinction-to-volume concentration, gradually decreasing), c250,d (extinction-to-particle (with a radius > 250 nm) number concentration, gradually increasing), and cs,d (extinction-to-surface-area concentration, gradually
decreasing) along both the transpacific and transatlantic dust transport
pathways. The retrieved dust-related conversion factors are anticipated to
inverse 3-D dust-related CCNC and INPC distributions globally, thereby
improving the understanding of ACIs in atmospheric circulation models.
Down in the dungeons: microbial redox reactions and geochemical transformations define the biogeochemistry of an estuarine sediment column

Published: April 2023

Abstract. The surface of intertidal estuarine sediments is typically covered with a photosynthetic biofilm. A large fraction of the carbon that is fixed is in the form of exopolymeric substances (EPS), providing the biofilm matrix. The consumption of organic carbon within the sediment column by heterotrophs bacteria is stratified according to the availability of electron acceptors used for organic matter degradation. This sequential use of electron acceptors strongly impacts geochemical gradients and early diagenetic processes within the sediment. In most studies, the distribution and role of the predominant microbial metabolisms is deduced from porewater chemistry and restricted to the upper decimeters of the sediment column, but rarely from direct measurements of microbial activity, potentially leading to erroneous conclusions of biogeochemical processes. We measured geochemical gradients in three estuarine sediment cores to a depth of 6 meters. Geochemical analyses of porewater and sediment were combined with measurements of microbial activity. In situ microelectrode measurements were performed for pH, oxygen and sulfide. Porewater was extracted and analyzed for major elements using Ion Chromatography, Inductively-Coupled-Plasma, and colorimetric assays for iron speciation. Porewater chemistry was compared to measurements of microbial activity including isothermal calorimetry and metabolic assays (triphenyltetrazolium chloride (TTC) and fluorescein diacetate (FDA)) and concentrations of EPS (sugars, proteins) measured in a previous study on the same cores. Finally, sediment composition was characterized through X-Ray Fluorescence core scanning. Results show that: (i) aerobic respiration occurred between 0 and 1 cm, (ii) nitrate reduction between 6 and 16 cm, (iii) sulfate reduction between 10 and 50 cm, (iv) manganese oxide reduction between 2–6 and 35–50 cm and (v) iron oxide reduction between 16–18, 24–26 and 35–45 cm. This is concomitant with the area where the microbial activity is the highest. In contrast to the literature, we conclude that some reactions, for example sulfate and nitrate reduction, were locally coupled or at least occurred concomitantly. Impacts of microbial metabolism on early diagenesis have been modeled via PhreeQc and predicted potential precipitation of metastable iron and/or sulfides. This is confirmed by iron and sulfur increases in sediments characterized through XRF. All these observations have been used to propose a biogeochemical model linking microbial metabolisms and early diagenesis that can be used as a basis for the study of other geochemical profiles in the future.
The Permafrost and Organic LayEr module for Forest Models (POLE-FM) 1.0
Authors: Hansen Winslow D. , Foster Adrianna , Gaglioti Benjamin , Seidl Rupert , Rammer Werner
Published: April 2023

Abstract. Climate change and increased fire are eroding the resilience of boreal forests. This is problematic because boreal vegetation and the cold soils underneath store approximately 30 % of all terrestrial carbon. Society urgently needs projections of where, when, and why boreal forests are likely to change. Permafrost (i.e., subsurface material that remains frozen for at least 2 consecutive years) and the thick soil-surface organic layers (SOLs) that insulate permafrost are important controls of boreal forest dynamics and carbon cycling. However, both are rarely included in process-based vegetation models used to simulate future ecosystem trajectories. To address this challenge, we developed a computationally efficient permafrost and SOL module named the Permafrost and Organic LayEr module for Forest Models (POLE-FM) that operates at fine spatial (1 ha) and temporal (daily) resolutions. The module mechanistically simulates daily changes in depth to permafrost, annual SOL accumulation, and their complex effects on boreal forest structure and functions. We coupled the module to an established forest landscape model, iLand, and benchmarked the model in interior Alaska at spatial scales of stands (1 ha) to landscapes (61 000 ha) and over temporal scales of days to centuries. The coupled model generated intra- and inter-annual patterns of snow accumulation and active layer depth (portion of soil column that thaws throughout the year) generally consistent with independent observations in 17 instrumented forest stands. The model also represented the distribution of near-surface permafrost presence in a topographically complex landscape. We simulated 39.3 % of forested area in the landscape as underlain by permafrost, compared to the estimated 33.4 % from the benchmarking product. We further determined that the model could accurately simulate moss biomass, SOL accumulation, fire activity, tree species composition, and stand structure at the landscape scale. Modular and flexible representations of key biophysical processes that underpin 21st-century ecological change are an essential next step in vegetation simulation to reduce uncertainty in future projections and to support innovative environmental decision-making. We show that coupling a new permafrost and SOL module to an existing forest landscape model increases the model's utility for projecting forest futures at high latitudes. Process-based models that represent relevant dynamics will catalyze opportunities to address previously intractable questions about boreal forest resilience, biogeochemical cycling, and feedbacks to regional and global climate.

Published: April 2023

The aim of this research is to determine the profile of preschool teachers who have enrolled in the education for Leader of Kinesiological Activities for Early and Preschool Children at the Faculty of Teacher Education of the University of Rijeka, as well as to predict it for future cycles. As many as 171 preschool teachers who completed their education for Leader of Kinesiological Activities for Early and Preschool Children, i.e. lifelong training programme, participated in the research. The basic descriptive parameters were calculated, and to determine the correlation between certain variables the Spearman’s correlation coefficient was used, the differences were determined by the Student’s t-test for independent samples, and to predict the future preschool teachers’ profile the linear regression analysis was used. The results indicate that the attendants were statistically significantly different (p<0.00) according to the criterion of completed study, i.e. preschool teachers with a completed graduate study are averagely seven years younger and have almost seven years of working experience less. A further trend of enrolment anticipates preschool teachers with less years of service and a completed graduate study. The greatest contribution offered by this research lies in the proven need of the participants for further training on the topic of integrated movement, while the large age span indicates a huge interest of preschool teachers with more, but also fewer years of service.

The nutritional status and the level of physical activity are very important components in the period of adolescence, and they can vary by type of settlement. Consequently, the aim of this research is to assess the differences in nutritional status and the level of physical activity among adolescents by type of settlement. This research includes 241 adolescents of both sexes in the territory of the municipality of Niksic, with a mean age of 15.7±0.5. The variables BMI, WHtR, and BF% were used to assess the nutritional status, while the PAQ-C questionnaire was used to assess the level of physical activity. Differences in the nutritional status by type of settlement were assessed using the Chi-square test with a statistical significance p≤0.05, while the differences in the level of physical activity were assessed using the T-test with a statistical significance p≤0.05. Statistical analysis was accomplished by SPSS 23.0 software. Results show, that for WHtR values, 11.1% of male and 18% of female adolescents were obese. Differences in nutritional status were not found by type of settlement. For values of physical activity, male adolescents had a score of 2.6±0.6, and female adolescents 2±0.6. Male adolescents didn't show differences in the level of physical activity by type of settlement, while female adolescents who lived in rural areas showed a lower level of physical activity during physical education lessons (p=0.031), short breaks (p=0.034), and lunchtime (p=0.013). It is necessary to raise awareness about the importance of nutritional status and level of physical activity in both urban and rural areas.

El objetivo del este estudio fue conocer la prevalencia de enteroparasitos en la Guarderia Niho de Praga, institución a la cual acudian niños de familias de escasos recursos. Se analizaron las heces de 256 niños cuyas edades oscilaban entre 0 a 12 años mediante un análisis coproparasitológico convencional con el uso de lugol para distinguir la morfologia de los parásitos.

Fue un estudio del tipo descriptivo y prospectivo, en el cual se encontró que el 62% de los niños estaban parasitados por una o más especies comensales y/o patógenos.

Con respecto a las especies parasitarias halladas, se encontr6 que más de la mitad de los niños estaban parasitados por el protozoo Blastocystis hominis (53%), en cambio solamente se halló un caso de parasitosis por el helminto Enterobius vermicularis.

Relacionando la edad con las especies parasitarias se halló que casi la mitad de los niños con edades entre 4 y 7 años presentaron Blastocystis hotninis, en cambio los helmintos como Hymenolepis nana y Enterobius vermicularis se presentaron solo en los niños mayores a 4 años. En los menores de 3 años no se presentó ningún caso de helmintiasis.

El 97% de los niños presentó una o más especies de protozoos comensales, en cambio solo el 12% presentó helmintos.

En cuanto a la cantidad de especies parasitarias halladas se encontró que los casos de poliparasitosis solo se presentó en el 1% de los ni´ños, en cambio el 53% estaban parasitados por solo un parásito (monoparasitismo). Se concluye que más de la mitad de los niños que asisten a dicha guarderia sufre de algún tipo de enteroparasitosis, situación que podria afectar su desarrollo.
