CONSERVADORISMO X RADICALISMO: UMA INVESTIGAÇÃO SOBRE INTERVENÇÕES EM EDIFÍCIOS HISTÓRICOS NO RECIFE.

As cidades estão em constante processo de transformação e a ideia de que o patrimônio arquitetônico deve permanecer intocado, tal e qual foi concebido, fica cada vez mais questionável, pois um dos principais requisitos para a preservação de um bem é mantê-lo em uso. Entretanto, as necessidades mudam de acordo com a evolução da sociedade, fazendo necessário dar uma nova função e significância a esses espaços. Intervir numa edificação de valor histórico introduzindo na mesma a marca da contemporaneidade, seja através de um novo uso, novas formas ou materiais, vêm sendo uma solução tomada por uma gama de arquitetos ao redor do mundo, para que o patrimônio continue sendo preservado, mas cedendo espaço para as marcas do tempo presente. Entre os diversos casos de intervenções em edifícios históricos, muitos se apresentam de modo que a contemporaneidade está nas minudências, enquanto que em outras está na inserção de volumes de linguagem arquitetônica diversa da existente nos edifícios antigos. Na pesquisa, constatou-se que este primeiro caso é bastante comum no Brasil e o segundo ocorre com maior frequência em outros países. Deste modo, fez-se necessário analisar as legislações de alguns países, buscando compreender porque essas intervenções mais ousadas que ocorrem de forma tão corriqueira no exterior ainda se encontra

Isokinetic analysis of ankle and ground reaction forces in runners and triathletes

OBJECTIVE: To analyze and compare the vertical component of ground reaction forces and isokinetic muscle parameters for plantar flexion and dorsiflexion of the ankle between long-distance runners, triathletes, and nonathletes. METHODS: Seventy-five males with a mean age of 30.26 (±6.5) years were divided into three groups: a triathlete group (n=26), a long-distance runner group (n = 23), and a non-athlete control group. The kinetic parameters were measured during running using a force platform, and the isokinetic parameters were measured using an isokinetic dynamometer. RESULTS: The non-athlete control group and the triathlete group exhibited smaller vertical forces, a greater ground contact time, and a greater application of force during maximum vertical acceleration than the long-distance runner group. The total work (180º/s) was greater in eccentric dorsiflexion and concentric plantar flexion for the non-athlete control group and the triathlete group than the long-distance runner group. The peak torque (60º/s) was greater in eccentric plantar flexion and concentric dorsiflexion for the control group than the athlete groups. CONCLUSIONS: The athlete groups exhibited less muscle strength and resistance than the control group, and the triathletes exhibited less impact and better endurance performance than the runners

A incidência do acidente vascular encefálico em pacientes infectados pelo SARS- COV-2, COVID-19: uma revisão de literatura: The incidence of brain vascular accident in patients associated with SARS-COV-2, COVID-19 infection: a literature review

Objetivo: O objetivo do trabalho foi analisar a possível relação entre a covid-19 e os acidentes vascular encefálicos (AVE). Métodos: A pesquisa foi realizada nas bases eletrônicas de dados eletrônicos PubMed, Lilacs e SciELO, nas quais foram selecionados artigos originais publicados entre 2020 e 2022. Os critérios de inclusão foram os artigos originais com texto completo disponível e estudos de casos publicados que analisaram a associação entre acidente vascular encefálico com a doença Covid-19. Foram considerados critérios de exclusão os artigos duplicados e de revisão ou aqueles que não se enquadravam ao tema proposto neste estudo. Resultados: Os principais resultados dos artigos analisados demostraram intrínseca relação entre Covid-19 e AVE, uma vez que o AVE isquêmico em pacientes com covid-19 tendem em alguns casos ocorrer por meio da trombose de grandes artérias, em pacientes com envolvimento pulmonar de grau leve a moderado. Além disso, foi constatado que na maioria dos pacientes houveram a presença de marcadores, como PCR, IL-6 e d-dímero e fibrinogênio elevados, presença frequente de anticorpos antifosfolípides, geração de espécies reativas de oxigênio e trombocitopenia. Ademais, foram identificados aumento dos casos em pacientes que apresentavam alguma comorbidade, como hipertensão e diabetes. Conclusão: Portanto, como os mecanismos das complicações do Covid-19 são recentes, se faz necessário a intensificação    de pesquisas nesta área, afim de agir precocemente nas complicações que a Covid-19 pode ocasionar

Shading and controlled-release fertilizer in the production of Oenocarpus bataua Mart. Seedlings

When associated an adequate shading and nutrition the seedlings to reach characteristics that allow them tosurvive in the field and increase production. Thus, this work aimed to evaluate the production of Oenocarpusbataua seedlings in response to different shade environments and controlled-release fertilizer doses. Thestudy was carried out from at the Embrapa nursery located in the municipality of Rio Branco, Acre state. Theexperimental design was complete randomized blocks with three replications and six plants per plot. Thetreatments were distributed according to a 4 x 5 factorial scheme, i.e., four shade environments (20%, 30%, 50%and 75%) and five CRF doses (0.0, 1.5, 3.0, 4.5 and 6.0 kg m–3) mixed with the substrate. Biometric, biomass andquality variables were evaluated at 305 days after transplanting. The ANOVA was applied for the qualitativefactor and regression analysis was performed for the quantitative factor, both at 5% probability. The treatmentswere grouped by analyzing canonical variables, a multivariate statistical and realized the Pearson’s correlationbetween variables was determined through correlation networks. The shading environment and the controlledreleasefertilizer positively influenced the growth and quality of Oenocarpus bataua seedlings. The seedlings ofOenocarpus bataua have better biometric characteristics produced in a nursery with 50% shading. Oenocarpusbataua seedlings show better quality when 3.88 kg m-3 of controlled release fertilizer are used

Influence of invertor and evertor muscle fatigue on functional jump tests and postural control: A prospective cross-sectional study

Objective: Fatigue of the ankle's stabilizing muscles may influence the performance of functional activities and postural control. The purpose of this study was to evaluate the performance of healthy young adults using functional jump tests and static posturography control under pre- and post-fatigue conditions of the ankle invertor and evertor muscles. Methods: Thirty physically active healthy male and female (15 male and 15 female) volunteers (24.3 years) were enrolled in this prospective cross-sectional study. Participants performed tests on one day under a non-fatigued state of invertor and evertor muscles and on the second day in a fatigued state. Tests included static posturography on a force platform in a bipedal stance with eyes open and closed and in one-legged support with eyes open and functional jump tests (figure-of-8, side hop, 6-m crossover hop, and square hop). Fatigue of the ankle invertor and evertor muscles was induced using isokinetic dynamometry with 30 repetitions at 120°/s. Results: Participants had an average age of 24.3 years (SD ± 2.08), the height of 1.73 m (SD ± 0.08), and a weight of 68.63 kg (SD ± 10.29). The average Body Mass Index (BMI) was 22.88 (SD ± 2.46). A decrease in performance was observed in functional activities and postural control under all conditions after the induction of muscle fatigue, except for the speed at a bipedal stance with eyes open. Conclusions: Functional jump tests are low cost and useful for clinical practice and evaluation of the effects of muscle fatigue and could be used in clinical practice

Biomechanical evaluation in runners with Achilles tendinopathy

OBJECTIVES: To evaluate the clinical characteristics, ground reaction force (GRF), and function of the plantar muscles and dorsiflexors of the ankle in runners with and without Achilles tendinopathy (AT) and in nonrunners. METHODS: Seventy-two participants (42 men, 30 women; mean age: 37.3±9.9 years) were enrolled in this crosssectional study and divided into three groups: AT group (ATG, n=24), healthy runners’ group (HRG, n=24), and non-runners’ group (NRG, n=24). Both ankles were evaluated in each group. The American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scale was used for clinical and functional evaluation. GRF was evaluated using force plates and muscle strength was evaluated using an isokinetic dynamometer. RESULTS: The AOFAS scores were lower in the ATG. The strike impulse was higher in the ATG than in the HRG and NRG. However, GRF was similar among the groups. The ATG exhibited lower total work at 120o /s speed than the HRG. The peak torque in concentric dorsiflexion was lower in the NRG than in the ATG and HRG. The peak torque and total work in concentric plantar flexion were lower in the NRG than in the ATG. The peak torque and total work in eccentric plantar flexion were lower in the NRG than in the ATG and HRG. CONCLUSION: Runners with AT showed higher strike impulse, lower muscle strength of the plantar flexors, and higher clinical and functional damage
