title: The use of dental services in the past year in the brazilian population: a systematic review with meta-analysis

description: Abstract The scope of this study was to analyze the factors associated with the use of dental services in Brazil. The review strategy included PubMed, SciELO, LILACS, BBO, EMBASE, Scopus, WOS and Google Scholar databases, in addition to repositories and databases of dissertations and theses. Studies were selected using the PEO (Population/Exposure/Outcomes) strategy. The outcome of this study was the use of dental services in the last year by the Brazilian population, treated as dichotomous variables for the following analyses: ≤ 1 year and &gt; 1 year. Mantel-Haenszel random effect meta-analysis was performed, estimating Prevalence Ratios (PR) and 95% confidence intervals (95%CI). A total of 94 studies were selected. The majority (98%) had a cross-sectional design, with 63% derived from primary data. For the meta-analysis, 25 studies were included. The use of oral health services in the last year was associated with higher education (≥ 8 years of schooling) (PR = 0.49, (95%CI: 0.39-0.60)); higher family income (≥ 2 minimum wages) (RP = 0.79, (95%CI: 0.74-0.84)); and living in urban areas (RP = 0.79, (95%CI: 0.64-0.97)). The availability of dental services in the Unified Health System needs to be made readily accessible to people with lower income, less education and those living in rural areas.

title: The extinction of the ignis fatuus

description: Ignis fatuus, a luminous phenomenon witnessed over the centuries by observers around the world, is no longer seen in modern times, suggesting that it is extinct. An explanation for this disappearance can be found in the description of ignis fatuus as a cool flame of methane. Unlike a conventional flame, which generates large amounts of heat, ignis fatuus is a flame that glows without heat through a chemiluminescence process. Its characteristic bluish color is due to the emission of excited formaldehyde, which is formed in the slow combustion of methane. It is generally accepted that the phenomenon is a spontaneous combustion of swamp gas in contact with the oxygen in air, but an analysis of the energies involved in the cool flame process indicates that the phenomenon is not spontaneous in nature. Experiments carried out in the 19th century show torches being used to ignite ignis fatuus. The abandonment of fire in favor of night lighting may hold the secret to this mystery of ignis fatuus’s extinction.

title: DETERMINATION OF DEGRADATION KINETIC PARAMETERS AND FAILURE TIME ESTIMATION OF MAGNESIUM TEFLON® VITON® ELECTRONIC “FLARE” COUNTERMEASURES

description: Flare type countermeasures that use the composition designated as MTV (Magnesium, Teflon®, Viton®), are the most used by Air Forces around the world. In Brazil, these “flares” are used in several locations and are subjected to different handling, storage and operation conditions that can affect their performance and compromise their service life. In this work, the Monte Carlo method was applied to estimate an empirical model to predict the lifetime of these countermeasures, using as variables the temperature and the relative humidity of the place where the material is used. The results were analyzed using multiple linear regression and analysis of variance. The kinetic parameters of material thermal degradation, such as Activation Energy and Pre-exponential Factor, and the estimated failure times of these countermeasures were determined. The results pointed out to strong temperature influence on material degradation resulting in different lifetimes for each site studied.

title: Effects of Saccharomyces Cerevisiae Supplemented Diet on Production Performance, Egg Quality and Humoral Immunity in Black Australorp and Fayoumi Layers

description: ABSTRACT The present study intended to identify the effects of the Saccharomyces cerevisiae yeast on production performance and parameters related to the quality of layers’ eggs. Effects of yeast on immune titers after routine vaccinations against Newcastle disease and infectious bronchitis were also studied. Fayoumi chicken (n=288) were divided in four groups (72 in each), and Black Australorp (n=288) in four groups (72 in each). Both had 12 weeks of age and were kept in 08 groups (3 replicates per treatment). Hens were fed a controlled diet along with the addition of 0.5g, 1.0 g, and 1.5 g of S. cerevisiae per kg of feed, till 25 weeks of age. Feed intake and egg production were measured on a daily basis, while body weight gain and egg weight were measured weekly. Egg quality parameters were evaluated by picking 5 eggs from every group weekly. Birds were vaccinated for Newcastle disease (ND) and infectious bronchitis (IB) at the 18th week. Subsequently, 10 days after vaccination, antibody titers were determined by Hemagglutination Inhibition and Enzyme Linked Immunosorbent Assay for both diseases. Results showed no significant effect of S. cerevisiae on layers’ weight gain and feed intake. However, egg production was increased in the experimental group. Moreover, yeast supplementation impacted positively on birds’ immune system. In conclusion, probiotic supplementation improved birds’ egg production and immunity.

title: Disposal of drugs and the ensuing environmental impacts: an integrative review of the literature

description: Abstract The scope of this article is to investigate the national and international evidence available on the forms of drug disposal and the presence of drugs in environmental matrices. It involved an integrative review of the literature conducted in the PubMed, SciELO and Virtual Health Library (VHL) databases, which included articles in English, Spanish and Portuguese published between 2010 and 2020. Twenty-six articles were selected, which revealed the incorrect disposal of medicines by professionals and consumers due mainly to the lack of knowledge about the environmental impacts that they may cause. Studies have highlighted the contamination of water, sewage and sediments by incorrectly discarded drugs. Furthermore, it was observed that aquatic living creatures can be impacted by the presence of drugs in environmental matrices. The incorrect disposal of drugs continues to be a reality in the evidence assessed, which leads to the contamination of environmental matrices and is often not removed by wastewater treatment plants and interferes with the equilibrium of environmental life.

title: Combined agricultural practices in millet and cactus: phyllochron, structural characteristics and relations with yield

description: ABSTRACT Variation in rainfall affects crops; therefore, agricultural practices become essential for forage production in semi-arid regions. This study aimed to evaluate the influence of different agricultural practices on phyllochron, structural characteristics of forage cactus and millet, and their relations with crop yield using the principal component analysis (PCA). The design was in randomized blocks, with six treatments: sole cropped cactus without straw mulching, sole cropped cactus with straw mulching, sole cropped millet without straw mulching, sole cropped millet with straw mulching, and cactus intercropping with millet, with and without straw mulching, each with four replicates. There were three cactus cycles and nine millet cycles (three cycles of cultivars BRS1501 and six of IPA Bulk-1-BF). Biometric parameters were evaluated monthly, while yield was determined after the crop harvest. Phyllochron was determined with the regression analysis. The PCA was applied to structural characteristics and yield. The systems adopted did not influence the structural characteristics of cactus and millet ( p &gt; 0.05), except for cladode thickness, which increased with straw mulching. Phyllochron of the millet reduced when the crop was intercropped. The structural characteristics of cladode length, width, and thickness influenced crop yield, mainly in systems with straw mulching. Straw mulching and intercropping alter phyllochron of cactus and millet. The adoption of straw mulching has a more significant relationship with cactus yield, whereas biometric variables influence crop yield for millet, not the cropping system.

title: Evaluation of Pelleting Mealworm (Tenebrio Molitor) Powder with Chokeberry By-product Meal To improve Duck Production and Meat Quality Traits

description: ABSTRACT This study aimed to evaluate the effects of dietary supplementation pelleted Tenebrio molitor (TM) powder with chokeberry by-product (CBP) meal on duck production and meat quality traits. A total of 180 0-day-old Pekin ducks were allocated randomly between three dietary groups viz., control, Treatment 1, and Treatment 2, with three pens per group and twenty birds per pen, characterized by increasing levels of pelleted TM powder with CBP meal in concentration of 0%, 1.5%, and 3%, respectively, and reared until 42 days of age in a completely randomized design. On day 42, the ducks were sacrificed, and breast and thigh muscles were used for meat quality evaluations. Feeding pelleted TM powder with CBP meal resulted in a significant difference in final body weight, weight gain and feed conversion ratio (p&lt;0.05). Additionally, a significant difference was observed in the pH of the breast meat samples (p&lt;0.05). As the only significant difference between the breast and thigh meat, 1,1-diphenyl-2-picryhydrazyl radical scavenging was influenced significantly by the dietary inclusion of pelleted TM powder with CBP meal (p&lt;0.05). However, the values of thiobarbituric acid reactive substances and meat color in both breast and thigh meat were insignificant (p&gt;0.05) different among all groups. To conclude, the inclusion of up to 3 % of pelleted TM powder with CBP meal in the diets of ducks did improve the growth production and antioxidant characteristics effects, which could decrease TBARS and reflected by changes in 1,1-diphenyl-2- picrylhydrazyl free DPPH radical scavenging values.

title: From production to impacts on health and the environment: an analysis of food systems in Brazil, Colombia and Panama

description: Abstract The scope of this article is to describe the main components of the food systems of Brazil, Colombia and Panama. It involved a narrative review of the literature from 2000 to 2022, based on the concept of food systems proposed by the Committee on World Food Security. A system of agro-industrial production, monoculture, use of pesticides and exploitation of natural resources predominates in all three countries, and the area occupied by family farmers is reduced. Multinational supermarket chains dominate food distribution, essentially in large urban centers, despite the increasing search for alternative models. Advances have been made in food labeling regulation (Colombia and Brazil) and in the taxation of sugar-sweetened beverages (Panama). The predominant food systems in these countries generate a significant and negative environmental impact, favor the consumption of ultra-processed foods, high prevalence of obesity and chronic non-transmissible diseases and increase in hunger, violating the human right to adequate food.

title: Fire severity in slash-and-burn agriculture in southern Brazil: an overview

description: ABSTRACT Slash-and-burn is a traditional agricultural system still widely used in Brazil. The variation in temperature during fires results in different levels of physical, chemical, and biological changes in the soil, which makes it necessarily better to understand the dynamics of fire severity in this system. The aim of this study was to make an analytical comparison of the variation in the temperature reached in the soil during fires in slash-and-burn agriculture. Temperature data were measured in burnt areas with similar fallow times at the following soil depths 0; 2.5 and 5 cm and compared with secondary data from other studies in the same slash-and-burn system in southern Brazil. The peak temperature showed more significant variations in the surface (0 cm) of different soils and different types of regeneration vegetation in each area. Overall, the peak temperatures ranged from 32 to 673 ºC across the three depths. The peak temperature reduction in the 5 cm layer was 88 % compared to the surface and 30 % compared to the 2.5 cm layer. The sandier soils showed greater thermal conductivity at depth. The surface litter seems to exert a more significant influence on the burning severity than the biomass load cut for burning, suggesting that the characteristics of the litter layer on the surface should be better characterized in future studies on fire severity.
