Abstract The objective of this work was to develop an index of adequacy to minimum biosecurity conditions (IAB) to express the external biosecurity level of pig farms in the state of Santa Catarina, Brazil. Pig farms of producers registered in the database of Companhia Integrada de Desenvolvimento Agrícola de Santa Catarina were sampled through an online questionnaire, with 76 questions on farm identification, production system, relationship with the agroindustry, herd size, and external biosecurity. One hundred questionnaires were answered by the farmers, showing the existence, partial existence, or absence of biosecurity practices, with scores of 1.0, 0.5, and 0.0, respectively, used to calculate the IAB of each farm. The farrow to weaning farms were grouped into three categories of production units (farrow to finishing, farrow to rearing, or farrow to weaning) and two of relationships with the production chain (integrated or independent). The investments necessary to achieve the ideal biosecurity practices were estimated. The farms with a low IAB (< 40%) represented 33% of the total, and the remaining 67% of the farms were classified with a medium or high index, evidencing a good external biosecurity. The IAB can be used to measure the biosecurity of pig farms and, based on their classification, to support the design of intervention plans.

Este artigo apresenta o projeto paisagístico para a revitalização do entorno do Canal do Anil, no Sub Bairro de Jacarepaguá, Gardênia Azul, Rio de Janeiro-RJ, Brasil, como TCC do Curso de Paisagismo, da Escola de Belas Artes – UFRJ. Ele parte de uma pesquisa, que visa a compreender a área numa visão macro e micro, realizada a partir de levantamentos bibliográficos e levantamentos físicos de campo. A área vem sendo ocupada, na sua maioria, por indivíduos de baixa renda que trabalham nos bairros vizinhos como a Barra da Tijuca, carentes por espaços públicos de lazer comunitários, acessibilidade adequada às moradias, infraestrutura urbana básica e qualidade da água e do solo. O Canal do Anil pertence a uma das sub bacias que confluem para a Lagoa da Barra da Tijuca. O seu percurso natural, que era composto por vegetação de Mata Atlântica, foi drasticamente agredido por assentamentos próximos e irregulares e, seu corpo hídrico, foi praticamente todo canalizado, o que também ajudou na deterioração da sua borda, que apresenta ocupação irregular densa, além de se configurar uma área pouco segura para os moradores e visitantes. Embora o local disponha de alguns pontos com serviços de abastecimento de água e luz, o esgotamento sanitário, na maioria das vezes o lixo é jogado diretamente no Canal, que sofre com problemas de mau cheiro, animais indesejáveis, suscetibilidade a doenças, alguns pontos de alagamento, redução da vegetação e aumento de áreas impermeáveis. Para a realização do trabalho partiu-se de um embasamento teórico-conceitual, levantamentos bibliográficos, com coleta de dados em publicações acadêmicas, plantas da Prefeitura e referências projetuais; levantamentos de campo, com visitas in loco, observações diretas não participativas, registros fotográficos e Base Google Earth. Os dados foram tratados a partir da confecção de mapas (biofísicos, figura e fundo, gabarito e uso do solo), cortes e desenhos. Foram utilizados, ainda, programas computacionais, como AutoCad e PhotoShop. Nos levantamentos foram constatados os principais problemas da população que habita o entorno do Canal, do próprio estado físico da sub bacia, além do potencial paisagístico e ambiental do local. • 1. O PROJETO PAISAGÍSTICO O projeto paisagístico proposto apresenta soluções para a revitalização do espaço, buscando atender à comunidade em suas reivindicações, respeitando suas necessidades e o meio ambiente local. A proposta oferece melhores condições de conforto, segurança e bem estar à população dotando a área de mobiliário e equipamentos urbanos que possibilitam a prática de esportes, o passeio seguro e o lazer infanto-juvenil e adulto, área para cães, mudança dos revestimentos de piso (melhoria da drenagem) e alargamento, onde possível, dos passeios, introdução de árvores, jardineiras e canteiros, melhoria da infraestrutura urbana, (sistema elétrico subterrâneo), implantação de sistema de coleta de esgoto sanitário, gás natural e água, onde ainda não há.

In this work, in addition to the quantitative and qualitative quantification of the biodiesel produced, the ability of the microalgae mix in the bioremediation of cattle wastewater (CWW) was also evaluated. The biomass separation was carried out by a chemically assisted ferric chloride. The supernatant (treated CWW) showed high COD, TOC, and NH
4 + removal efficiency of 99.5, 99, and 98.6%, respectively. The dry biomass produced during the cultivation varied between 0.5 and 5.1 g L−1 and the lipid concentrations between 11 and 14%. The fatty acid in the highest concentration in the biomass was palmitic (C16:0), ranging from 75.7 to 81%. Linoleic acid (C18:3) ranged from 12.3 to 14.1%, indicating reasonable oxidative stability of biodiesel. The calculations based on the fatty acids showed a cetane number of 58.8, an iodine number of 54.14, and an oxidation stability of 7.75 h. Although there are good conditions for using the produced biodiesel, it is recommended that it be mixed with other biofuels that have greater oxidative stability. Overall, this is a new sustainable route for biofuel production with the benefit of carrying out wastewater bioremediation at the same time. [ABSTRACT FROM AUTHOR]- Published

Made available in DSpace on 2022-04-29T08:36:55Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-06-01 The facial skeleton in pediatric patients can undergo several changes during development, according to their growth zones and the traumas they suffer. Thus, some of these traumas can lead to multiple complications if not treated properly. Epidemiology can vary according to the social, cultural, and environmental aspects of each individual. Therefore, each case must be treated individually, and it is important to consider age-specific aspects, such as the high osteogenic potential, which leads to faster bone healing. The use of resorbable fixation materials in facial fractures of pediatric patients is widespread, with good acceptance and great advantages over conventional titanium materials, mainly for the elimination of a second surgery to remove the materials. The present study aims to report a series of clinical cases of infants, who suffered trauma and evolved with fractures in the facial bones. Surgical treatment was instituted to reduce and fix fractures, using the resorbable system. Patients are followed up with periodic outpatient follow-up visits and have a good case evolution.

The purpose of this study was to perform a systematic review and meta-analysis of randomized clinical trials (RCTs) investigating the efficacy of hilotherapy on postoperative pain, swelling, neurosensory impairment and patient satisfaction. The authors analyzed RCTs comparing the use of hilotherapy versus conventional cryotherapy or no cold treatment for orthognathic surgery and repair of facial trauma. The authors assessed the risk of bias and strength of evidence according to the Cochrane guidelines and GRADE rating system, respectively. Treatment effects were defined as weighted or standardized mean difference using the inverse variance method. Five RCTs were included. Postoperative pain and swelling in patients using hilotherapy were lower comparing to the control group in the postoperative day 2 (Pain: MD -1.75, CI 95% -2.69 to -0.81; Swelling: MD -21.16 mL, CI 95% -38.91 to -3.41) and in the final evaluation (Pain: MD -0.31, CI 95% -0.44 to -0.18; MD -4.45 mL, CI 95% -7.87 to -1.03). Patients reported higher satisfaction with hilotherapy, but no differences were found for neurosensory impairment. Current evidence suggests that hilotherapy is effective in reducing postoperative pain and swelling in orthognathic surgery and repair of facial fractures and may lead to improvements in patient satisfaction in the recovery phase.

Pig houses provide a highly aggressive environment to concrete structures. The chemical aggressiveness generated by pig manure may cause wear, loss in strength and premature damage to floors, leading to animal hoof diseases. Since the chemical attack in cementitious structures is controlled by its porosity and permeability, the use of mineral admixtures in cement is convenient. This work evaluated the behaviour of cement mortars with nano-silica and silica fume (micro-silica) to an acid attack, simulating the effects of acids present in pig manure to cementitious materials. Two cement mortars were tested: one with nano-silica as an additive and another with nano-silica and silica fume (cement replacement of 10%), as well as a control mortar with Portland cement. The mortars were submitted to acid attack cycles for four weeks. The compressive strength at 35, 50 and 65 days, mass loss and water absorption after 65 days were evaluated. Mortars containing nano-silica and silica fume showed considerable loss of workability, however showed the best performance in all studied aspects, indicating that the simultaneous use of these additions may result in longer-lasting concrete structures in pig houses.

This research evaluated the influence of temporary cements (eugenol-containing [EC] or eugenol-free [EF]) on the tensile strength of Ni-Cr copings fixed with self-adhesive resin cement to the metal coronal substrate. Thirty-six temporary crowns were divided into 4 groups (n=9) according to the temporary cements: Provy, Dentsply (eugenol-containing), Temp Cem, Vigodent (eugenol-containing), RelyX Temp NE, 3M ESPE (eugenol-free) and Temp Bond NE, Kerr Corp (eugenol-free). After 24 h of temporary cementation, tensile strength tests were performed in a universal testing machine at a crosshead speed of 0.5 mm/min and 1 kN (100 kgf) load cell. Afterwards, the cast metal cores were cleaned by scraping with curettes and air jet. Thirty-six Ni-Cr copings were cemented to the cast metal cores with self-adhesive resin cement (RelyX U200, 3M ESPE). Tensile strength tests were performed again. In the temporary cementation, Temp Bond NE (12.91±2.54) and Temp Cem (12.22±2.96) presented the highest values of tensile strength and were statistically similar to each other (p>0.05). Statistically significant difference (p0,05). Diferença estatisticamente significante (p
