Published: September 2022

Este artigo tem por objetivo mostrar o processo produtivo do cimento identificando seus impactos Ã saúde humana, desde a extração de matéria-prima, que gera degradação e contaminação da água e do solo, passando pela emissão de material particulado, causador de muitos problemas respiratórios. No Distrito Federal, na região da Fercal em Sobradinho, a presença de duas grandes fábricas gera impacto Ã saúde das comunidades próximas. Na Comunidade de Queima Lençol, localizada nas proximidades de uma destas fábricas, há forte poluição gerada pela emissão de material particulado, oriundo da fabricação do cimento, o que vem causando graves problemas respiratórios Ã população local.

Authors: Alves Ramiro Patrícia , Granado Romero Danielli 
Published: September 2022

Novas configurações do campo nas sociedades contemporâneas vêm resultando na denominada nova ruralidade. Nesse cenário, o meio rural ultrapassa a dimensão agrícola, Ã qual esteve vinculado durante bastante tempo, e abarca uma multiplicidade de funções, dentre as quais se destaca o turismo. Nesse artigo apresentaremos considerações iniciais, baseadas em nossa experiência no assentamento Nova Pontal, município de Rosana (SP). Mais especificamente, interessa-nos aqui o espaço rural dos assentamentos no Brasil, com ênfase analítica sobre os aspectos da divisão sexual do trabalho, organização social e questão ambiental relacionada Ã atividade turística. Para tanto, foram adotadas, além de metodologia participativa, técnicas como a observação participante e a coleta de depoimentos gravados. Do ponto de vista sociológico, notamos que a abertura destes espaços Ã visitação representa, por um lado, uma função simbólica relevante para campesinos e citadinos e, por outro, poderá vir a ser uma força motriz para a recuperação e/ou conservação do meio ambiente.

Authors: Pacheco Jessé Morais , Hoff Debora Nayar 
Published: September 2022

O desenvolvimento sustentável precisa ser encarado a partir do entendimento das múltiplas relações causais entre meio ambiente e os atores do sistema. Em sistemas agroindustriais isso urge devido Ã dependência entre processos de produção, qualidade dos ecossistemas, regimes climáticos e condições físico-químicas do solo. O objetivo do estudo é organizar, a partir de estudos publicados sobre o tema, os fluxos de Matéria e Energia já identificados para o setor sucroalcooleiro, apresentando um panorama geral do seu grau de fechamento de ciclo. É uma pesquisa descritiva com uso de fontes secundárias de dados e informações. Destacam-se nos resultados: i) reutilização do bagaço para cogeração de energia; ii) alta taxa de reutilização de água, que possibilita baixa captação deste insumo da base de recursos hídricos; e iii) possibilidade de tratamento da vinhaça, torta de filtro e cinzas, orientadas aos processos de fertirrigação e/ou biodigestão.
Discursos e práticas sociais da sustentabilidade a partir da pecuária bovina brasileira
Authors: Claudino Livio Sergio Dias 
Published: September 2022

O tema da sustentabilidade é bastante abrangente, polêmico e multifacetado, especialmente quando se assume a existência de divergências sobre seus significados, como praticá-la, ou mesmo se é materializável ou apenas ideologia. Pontos de vista e abordagens distintas conduzem a diferentes mecanismos para a operacionalização e a consequentes resultados diversos da sustentabilidade. Esse texto tem por objetivo analisar a construção discursiva e de práticas associadas Ã noção de sustentabilidade no contexto da pecuária bovina brasileira. O artigo fundamenta-se em pesquisa bibliográfica em diversas fontes, desde artigos mais teóricos, passando por relatórios de conferências sobre meio ambiente até textos técnicos e estudos de casos que relacionam a pecuária bovina e os impactos ambientais. Evidenciou-se a institucionalização tecnocrática de “modelos estratégicos” chamados de “pecuária sustentável”, que são distintos entre si, na natureza e forma e, principalmente, nas prioridades e mecanismos de efetivação.

Background: Symbiotic association with different microbes is an integral and ecologically vital component of legumes. Most previous studies focused on sole application of microbial agents, with limited studies investigating the effects of co-inoculation of different microbial agents under different tillage practices on soil properties. The current study aimed to assess the effect of tillage practice and seed treatment with different biofertilizers inoculations on the soil chemical properties and nodulation under faba bean (Vicia faba L.) crop. Methods: The study was conducted in factorial randomized block design (FRBD) with two tillage system viz., T1: Conventional tillage (CT), T2: Zero tillage (ZT) and eight biofertilizer inoculation combinations of Rhizobium spp., phosphorus solubilizing bacteria (PSB) and vesicular arbuscular mycorrhizae (VAM) replicated three times during rabi 2019-20. Result: Zero tillage and biofertilizer inoculations significantly increased organic carbon, available nitrogen and phosphorus content of the soil. The number of nodules/plant, nodules fresh and dry weight/plant were recorded significantly higher in ZT as compared to CT and in seed treatment with Rhizobium spp. + PSB + VAM over other inoculations except Rhizobium spp. + VAM. The content of DTPA (Diethylenetriamine pentaacetate)-extractable Fe and Mn in soil was significantly enhanced by seed treatment with biofertilizer.

Published: September 2022

Based on the potential of teaching Philosophy in the reflection on Quality of Life, with a qualiquantitative approach, this exploratory research investigated the Quality of Life of students and teachers in classes of integrated technical Accounting and Informatics courses at the Federal Institute of Paraíba, at João Pessoa campus. Two mixed instruments were used in the Physical, Psychological, Social Relations and Environment Domains, adapted from a form of the World Health Organization, with a sample of 14 students and 4 professors. Quantitative data from students and professors highlighted higher levels in the Social Relations Domain and lower levels in the Physical Domain. The Teacher's self-assessment regarding Quality of life obtained an average index of 4.00; the Students’ rating for this item reached 3.85. In each case, greater self-care is suggested, demanding attention from the Institution and the social apparatus. The financial vulnerability of students was verified, demanding financial, emotional and psychological support, and the need for greater attention and support to teachers' mental health. The contents of the open questions were analyzed, using the methodology of Bardin (1977), bringing relevant contributions on the perception of the Quality of Life concept.

Thiols are a group of highly potent aroma compounds found in many Vitis vinifera wines. In berries, thiols occur as precursors formed from a thiol attached to an amino moiety (e.g., cysteine and glutathione). Foliar sulfur and urea supplementation has been found to increase thiol precursors in V. vinifera berries. However, such data are still scarce for interspecific hybrid Vitis varieties, despite a growing interest in these cultivars. In this study, eight thiol precursors, 21 amino acids and glutathione (GSH) of seven white hybrid Vitis varieties collected in Quebec, Canada, were quantified by liquid chromatography with tandem mass spectrometry. Then, the impact of foliar sulfur and urea supplementation on thiol precursors of fully mature berries was tested on the Vitis sp. Vidal, using a complete randomised block design. Among the analysed thiol precursors, only the precursors of 3-mercaptohexan-1-ol (3MH) were detected, with glutathione-3MH (20-711 μg/kg berry fresh weight) as the main precursor in most studied varieties. Vidal samples had the highest concentrations of glutathione-3MH (313 μg/kg berry fresh weight) and GSH (17 mg/L in juice), but a large variability was found among the biological replicates. The amino acids proline, arginine, glutamine and alanine were the main amino acids found in Vidal, Frontenac blanc, Seyval blanc and Saint-Pepin respectively. Correlation analysis showed no significant relationship between thiol precursor and glutathione/amino acid content in berries. Foliar urea and sulfur supplementation had no impact on thiol precursor concentration in Vidal. However, a trend in a higher content of thiol precursors in berries treated with urea and sulfur compared to the control was observed on one of the two experimental sites.

Published: September 2022

Abstract
Zinc (Zn) was identified as one of the most toxic heavy metals and often found contaminating the water sources as a result of inefficient treatment of industrial effluent. A Green Emulsion Liquid Membrane (GELM) was proposed in this study as a method to minimize the concentration of Zn ions in an aqueous solution. Instead of the common petroleum-based diluent, the emulsion is reformulated with untreated waste cooking oil (WCO) collected from the food industry as a sustainable and cheaper diluent. It also includes Bis(2-ethylhexyl) phosphate (D2EHPA) as carrier, Span 80 as surfactant, sulfuric acid (H2SO4) as internal phase and ZnSO4 solution as external phase. Such formulation requires a thorough understanding of the oil characteristics as well as the interaction of the components in the membrane phase. The compatibility of WCO and D2EHPA, as well as the external phase pH was confirmed via liquid-liquid extraction (LLE) method. To obtain the best operating conditions for Zn extraction using GELM, the extraction time and speed, carrier, surfactant and internal phase concentrations, and W/O ratio were varied. 95.17% of Zn ions were removed under the following conditions; 0.001M of H2SO4 in external phase, 700 rpm extraction speed for 10 minutes, 8 wt% of carrier and 4 wt% of surfactant concentrations, 1:4 of W/O ratio and 1 M of internal phase concentration.

Abstract
Background: Human breast milk is a complex fluid that provides both macronutrients and micronutrients critical for the infant development. Several studies have been focused on the characterization of the human breast milk (HBM) microbiota, nowadays we know it is composed by a rich community of bacteria, viruses, protozoa and anaerobic fungi. However, it is considered that the human microbiome is not static, instead is described as a dynamic living system shaped by several factors like age, demography, malnutrition, sex, diet, sexual behavior, antibiotics and health condition. Previous studies have demonstrated that metabolic disorders such as diabetes mellitus induces dysbiosis in the gut microbiome in affected individuals. However, how gestational diabetes mellitus (GDM) affects the HBM microbiota remains poorly understood. In this study, we analyzed the bacterial diversity through the massive sequencing of the 16S rRNA in Colombian infants breastfed with HBM from GDM and control women.
Methods: In this descriptive cross-sectional study, we collected HBM and stool samples from GDM and healthy mother-infant pairs in Pereira (Colombia). The whole DNA was purified and the 16S V3-V4 region was amplified and sequenced. Reads obtained were quality filtered and classified by homology according to the Ribosomal Small Subunit SILVA.
Results: Our results revealed that the most abundant phyla in the collected samples are Firmicutes, Bacteroidetes and Proteobacteria. Interestingly, we found significant differences in the bacterial relative abundances GDM mothers’ gut compared to the control group, notably Bifidobacterium, Serratia and Sutterella were negatively associated to GDM. In the HBM significant differences were observed in Sutterella, Serratia, Lactococcuswere in low RA in GDM whereas Veillonellawas in high RA. On the other hand, in the infant, Bifidobacterium, Lactobacillus, Sutterella, Serratia, Streptococcus, and Veillonella had low presence while Lactococcus and Flavonifractor were in significant high abundance in GDM, these differences in the bacterial community structure in GDM mother and their infants could be linked to vitamin K and several forms of vitamin B deficiency, inflammatory disease, and gut bacterial homeostasis.
Conclusion: Our results suggest that gut bacteriome profiles vary between healthy and GDM women, leading to gut bacterial dysbiosis in their infants.

Abstract
Alginate is known as an immunostimulant; however, the comprehensive and simultaneous study on its co-activity with Lactobacillus bulgaricus resolves the relationship of feed digestibility, hematological parameters, and upregulation of the regulation of feed digestibility immune-related gene expression, and disease-resistant in Artemia has not been covered. This study aimed to determine the effect of alginate with Lactobacillus bulgaricus bio encapsulated Artemia in Vibrio vulnificus, V. parahaemolyticus, and V. harveyi challenged. Compared to the non-probiotic alginate, co-probiotic L. bulgaricus activated and improved the mortality rate of 400 ppm alginate from 100% to 30-70% at 36 hours with CMI of 276-702±0.00-101.82 and a mortality reduction of 41.21-74.59±0.05-15.90%. The co-activity of 400 ppm alginate and L. bulgaricus resulted in the higher Phenol Oxidase and Superoxide Dismutase Activity. Beta-glucan and proPO gene expression was also upregulated 233.44% and 185.17%, respectively. The gut evacuation time and fullness have also resulted in better performance than 800 ppm alginate without probiotics. Alginate and L. bulgaricus probiotics have cooperated synergically through pre and probiotic mechanisms. This Artemia bio model defines that this combination will reduce alginate as an immunostimulant and cut off the large-scale utilization in ponds.

Abstract
Background
The first wave of the COVID-19 pandemic reached Germany between March and May 2020. In order to contain the spread of the virus and particularly protect vulnerable people, the government imposed a lockdown in March 2020. In addition to infection control measures, such as hygiene and social distancing requirements, a general ban on access to nursing homes for relatives and external service providers was issued.
Methods
To investigate the challenges and consequences of the enacted infection prevention measures and specific strategies for nursing homes in Germany, a multicentre cross-sectional qualitative interview study with nursing home managers and ward managers was conducted. Recorded audio data were transcribed, analysed using thematic framework analysis and reflected in peer debriefings.
Results
78 interviews with 40 nursing home managers and 38 ward managers from 43 German nursing homes were conducted. At organisational level, appointing a multi-professional crisis task force, reorganizing the use of building and spatial structures, continuous adaption and implementation of hygiene plans, adapting staff deployment to dynamically changing demands, managing additional communicative demands and relying on and resorting to informal networks were topics identified in response to the challenges posed by the pandemic. At direct care level, changed routines, taking over non-nursing tasks, increased medical responsibility, increased documentation demands, promoting social participation and increased communication demands were identified as topics in dealing with the challenges of the COVID-19 pandemic. Also various negative consequences were identified, such as psychological stress and negative emotional consequences. Positive emotional consequences such as a newly established team cohesion, the feeling of a calm atmosphere and a stronger sense of connection between nursing staff and residents were also reported.
Conclusions
The results of the described challenges, strategies and consequences allow recommendations as basis for possible approaches and successful adaptation processes in nursing home care in the future. There is also a need for local networks to act in a coordinated way and a need for quantitative and qualitative support for nurses, such as staff support as well as advanced nursing practice, to cope with the challenges of the pandemic.

Published: September 2022

Abstract
BACKGROUND
A myriad of symptoms associated with COVID−19 have been reported in the literature. It's currently unclear if these symptoms are part of a normal clinical pattern directly induced by SARS-CoV−2 infection or are secondary to the patient's compromised systemic condition, given the probability of coinfections, immunosuppression, and treatment-related adverse effects (4). The aim of this research was to find answers to the question"What is the prevalence of oral symptoms in COVID−19 patients?“.
METHODS
A questionnaire was designed to detect and identify changes in the oral mucosa in patients with COVID−19 infection. During their follow-up at the Gölcük State Hospital COVID Outpatient Clinic, clinicians and an academic specialist performed a face-to-face survey of the patients. Participants were informed about the purpose of the study and their consent to participate in the study was obtained along with their signatures on the questionnaire form. The data was collected between April 12 and May 22, 2020, and it was analyzed, archived, and processed anonymously.
RESULTS
This survey included 306 COVID−19 patients in total. The results revealed that only 29.4% of respondents had complaints of oral aphthae and ulcers and 18.94% experienced oral pain; with the most commonly reported symptom being xerostomia (67,6%). There was a widespread distribution of reported symptoms with varying incidences and locations.
CONCLUSION
Analyzing the data this study procured, one still can’t conclusively determine whether the oral manifestations develop secondary to COVID−19.
Assessment of different experimental setups to determine viral filtration efficiency of face masks
Authors: Filipić Arijana , Fric Katja , Ravnikar Maja , Kogovšek Polona 
Published: September 2022

Abstract
As a result of the pandemic COVID -19 many new materials and masks came on the market. To determine their suitability, several standards specify which properties to test, including bacterial filtration efficiency (BFE), while none describe how to determine viral filtration efficiency (VFE), a property that is particularly important in times of pandemic. Therefore, we focused our research on evaluating the suitability and efficiency of different systems for determining VFE. Here, we evaluated the VFE of 6 mask types (e.g., a surgical mask, a respirator, material for mask production and cloth masks) with different filtration efficiencies in four experimental setups and compared the results with BFE results. The study included 17 BFE and 22 VFE experiments with 73 and 81 mask samples tested, respectively. We have shown that the masks tested had high VFE (>99% for surgical masks and respirators, ≥98% for a material and 87-97% for cloth masks) and that all experimental setups provided highly reproducible and reliable VFE results (coefficient of variation < 6%). Therefore, the VFE tests described in this study can be integrated into existing standards for mask testing.
