title: Thermal comfort and IAQ conditions of naturally ventilated classrooms during the Covid-19 pandemic

description: Abstract In order to achieve good thermal comfort and indoor air quality (IAQ) conditions in naturally ventilated classrooms, adequate air change rates must be ensured. In 2020, this issue became especially relevant due to the Covid-19 pandemic, since it may contribute to minimize the transmission potential of respiratory diseases. This study aims to evaluate the thermal comfort and IAQ conditions of a naturally ventilated classroom, in order to identify scenarios that contribute, simultaneously, to the reduction of the risk of dissemination of the SARS-CoV-2 virus and to the maintenance of thermal comfort for users. Environmental variables were monitored in a classroom before and during the Covid-19 pandemic and a simulation model was calibrated. Scenarios varying the number of occupants and the air change rate were simulated in order to assess the impact of these variables on the CO 2 concentration, on the infection probability and on the indoor operative temperature. The best scenario showed a reduction of 42% in the concentration of CO 2 and 33% in the infection probability and an increase of 60% in comfort hours, compared to the worst scenario. However, the strategies adopted must be analysed for each situation, as well as the risks and benefits for classroom occupants.

title: Palliative care management by caregivers in home care: theoretical validation in a conversation circle

description: ABSTRACT Objectives: to present the validation process of a Grounded Theory on the management of palliative care at home by a caregiver of a family member who experiences a death/dying process. Methods: a qualitative, explanatory research, which validated a theoretical matrix through a conversation circle containing 15 family caregivers and nine healthcare professionals, in December 2018. Results: forty-six propositions were validated regarding family caregivers’ contextual, causal, intervening conditions, consequences and action strategies to deal with the dying and death process of a family member. Conversation circles encouraged dialogue and (re)signification of the senses and knowledge of those involved, proving to be a way of educating and promoting the exercise of citizenship by participants. Final Considerations: the conversation circle made it possible for participants to interact and share information and experiences regarding home care for palliative patients and their families.

title: Post-Cretaceous brittle tectonics in the Tunas Alkaline Complex, Paraná, Brazil

description: Abstract We present a study of the brittle tectonics of Tunas Alkaline Complex focusing on the kinematic and geometric analysis of faults and brittle shear zones deforming the complex. The data acquired and respective interpretations sought to contribute to the post-Cretaceous tectonic structural models of southern Brazil. The ~83 Ma-old alkaline complex is made up of syenites, alkali syenites, plutonic and volcanic breccias, as well as trachyte, microsyenite, and bostonite dykes. Morphostructural analysis using remote sensing combined with right dihedral kinematic analysis of fault-slip data and relations of intersections among structures allowed us to characterize four Cenozoic paleostress fields and their respective tectonic pulses: (I) Eocene-Oligocene NW-SE extension responsible for normal oblique-slip faults striking N60-70E; (II) Oligocene-Miocene NE-SW compression associated with tectonic accommodation of the South American Plate at circa 27-26 Ma, and responsible for WNW-ESE-trending sinistral and NE-SW-trending dextral strike-slip faults; (III) Plio-Pleistocene N-S to NNW-SSE compression related to dextral reactivation of NW-SE-striking faults, sinistral reactivation of NE-SW-trending faults, and generation of NNW-SSE-trending strike-slip faults; and (IV) Pleistocene-Holocene NW-SE to WNW-ESE compression that caused dextral reactivation of ENE-WSW-trending faults and sinistral strike-slip reactivation of NNW-SSE-trending faults.

title: Impact of shading devices on pressure distribution in a generic model

description: Abstract Natural ventilation in buildings is an important passive strategy to maintain indoor air quality and comfortable thermal environments. The pressure differential on buildings’ façades, quantified by the wind pressure coefficients (WPCs), directly impacts the performance of natural ventilation. Several factors, as wind direction, surroundings, terrain type, building geometry and facades’ details influence wind pressure distribution. Many investigations use wind tunnel tests or computational fluid dynamics simulations to evaluate the Cps in regular geometries. This paper aims to evaluate the impact of external shading devices on the WPCs of a generic isolated model with 3.0 m x 3.0 m x 2.7 m with two openings (with 1.0 m 2 each), centralised and placed on opposite façades with a windowsill measuring 1.1 m. Thus, from its reduced version (scale 1:7.5), five configurations (model without shadings, sealed model and model with openings, and typologies with horizontal, combined and vertical shading devices) are tested in a wind tunnel with eight wind attack angles (0° to 90° and 180°). The results show greater differences in cases with vertical shading devices exposed to wind attack angles of 45°, 60° and 75°.

title: Shear design of steel fiber reinforced concrete beams without stirrups: a parametric analysis

description: Abstract Some standards present design recommendations for the shear of fiber reinforced concrete beams, but with there are differences between them. Thus, the aim of this article is to perform the shear design and parametric analysis of beams in steel fiber reinforced concrete (SFRC), without stirrups, based on the methods proposed by the recently released NBR 16935:2021, the FIB Model Code 2010, RILEM TC 162-TDF and the German standard. The study involved a literature review, researching publications of experimental tests involving SFRC beams, with longitudinal reinforcement and without stirrups, aiming to obtain experimental values to compare with the standards’ theoretical predictions of shear capacity. For the parametric analysis, the researchers sought studies with residual tensile strength results based on the EN 14651 test, which is similar to the test recommended by NBR 16935:2021. The parameters that varied were width (b w ), useful height (d) and longitudinal reinforcement ratio (ρ). The results showed that NBR 16935:2021 and the FIB Model Code 2010 present, on average, characteristic values that are far from the experimental results, being more conservative than the other standards. The longitudinal reinforcement ratio had the greatest influence on the results compared with the other analysed parameters.

title: Wild fauna received by the Wild Animal Screening Centre and referred to the Veterinary Hospital of the University of Brasília

description: Abstract The aim of this work was to analyze records from two institutions that work with wild animals throughout 2018. Data were obtained from the animals received by the Wild Animal Screening Centre of Federal District (CETAS-DF), Brazil, referring to the type of admission and destination, species, as well as animals that required veterinary care and were referred to the Wild Animal Sector of the Veterinary Hospital of the University of Brasilia (HVet-UnB) with description of the main conditions and temporal analysis. Of the 7,603 animals that were admitted to CETAS-DF (6,646 birds, 461 mammals and 496 reptiles), 1,028 individuals (13.52%) required veterinary medical care and were referred to HVet-UnB. The class of animals that most needed assistance was birds (765), followed by mammals (225) and reptiles (37). Unlike other fauna diagnostic surveys from environmental agencies, this is the first study that correlates the numbers of animals received by a CETAS and that were referred for veterinary medical follow-up. The high number of wild animals that require referral to specialized institutions reinforces the need to establish agreements and structure for veterinary medical treatment and subsequent rehabilitation of these specimens as part of an action plan for the conservation of biodiversity in the country.

title: TAX GOVERNANCE: A STUDY OF ITS EFFECTS ON TAX EVASION

description: ABSTRACT This study aimed to verify the relationship between tax governance and tax evasion. The motivation to analyze this interaction lies in the need to understand and prove that tax governance practices have an effect on the level of tax evasion. The results confirm the theoretical hypothesis that was tested: the countries in the sample with corporate tax governance practices presented lower levels of tax evasion, which is important empirical evidence of this relationship that has been postulated, but not yet verified by the literature. As for additional results, it was determined that only enforcement evokes the behavior expected from the literature, suggesting that it has a complementary relationship with tax governance. Thus, this paper supports the inclusion of another factor associated with our understanding of the tax evasion phenomenon, expanding our knowledge on the subject through the possibility of comparison with similar international studies. Furthermore, it may also generate government interest in encouraging the implementation of tax governance by companies.

title: Adoption of e-government: a study on the role of trust

description: Abstract This study analyzed the influence of trust and trustworthiness on the intention to adopt and use e-government services. A structural model was proposed, considering the relationship among Ability, Benevolence, Integrity, Perceived Risk, Trust of the Government, Trust of the Internet and Disposition to Trust. The model was tested through structural equation modeling (partial least square method). An online questionnaire was applied, including 36 items for all the constructs presented in the model, and measured with 11-point Likert scales. After the first round of analysis, an alternative model was proposed with a better fit. Results indicated that: 1) Ability, Benevolence, and Integrity, together, positively influence Trust of the Government; 2) Trust of the Government and Trust of the Internet positively influence Trust in e-Government; 3) Trust in e-Government negatively influences Perceived Risk and positively influences Intention to Use and; 5) Perceived Risk negatively influences Intention to Use. Considering the results of this research, as government agencies increase their expenditure to implement and maintain e-gov initiatives, they must recognize and deal with trust-related issues.
