Rugby na/da escola: possibilidades de diálogo com a cultura corporal

O presente estudo teve como objetivo principal investigar as possibilidades de intervenção pedagógica no cotidiano escolar, por meio do rúgbi. Simultaneamente propor o rúgbi como um possível conteúdo para as aulas de Educação Física, discutindo a referida modalidade esportiva como uma possível linguagem corporal (COLETIVO DE AUTORES, 1992). O campo de investigação foi constituído durante as observações realizadas durante o estágio supervisionado no ano 2009 na Escola Municipal Mato Grosso do Sul no município de Volta Redonda. Como escopo metodológico optamos pela pesquisa bibliográfica, na intenção de constituir um arcabouço teórico que nos permitiu fundamentar uma proposta de intervenção na escola utilizando o referido esporte como um dos conteúdos possíveis de serem abordados nas aulas de Educação Física. Ao mesmo tempo, constituímos um campo que nos permitiu realizar uma observação simples das ações pedagógicas realizadas com os discentes da referida escola. As atividades de observação foram desenvolvidas aos sábados de oito as doze horas, no período compreendido entre março e julho de 2009. Dessa forma, vivenciamos o cotidiano da escola em 2009, por meio do Estágio Supervisionado em educação Física Escolar, percebendo que o individualismo exacerbado é um comportamento dos alunos que emerge durante as aulas de educação física, promovendo diversos conflitos e tensões nas relações estabelecidas entre os alunos e professor. Outro aspecto importante, que for observado durante a pesquisa, foi a dificuldade de inserir conteúdos ainda não conhecido pelos discentes, pois apenas algumas modalidades esportivas são priorizadas por alunos e professores e, ainda em alguns casos, com a ênfase no caráter técnico-esportivo

Analysis Of The Ergosterol Biosynthesis Pathway Cloning, Molecular Characterization And Phylogeny Of Lanosterol 14 α-demethylase (erg11) Gene Of Moniliophthora Perniciosa.

The phytopathogenic fungus Moniliophthora perniciosa (Stahel) Aime & Philips-Mora, causal agent of witches' broom disease of cocoa, causes countless damage to cocoa production in Brazil. Molecular studies have attempted to identify genes that play important roles in fungal survival and virulence. In this study, sequences deposited in the M. perniciosa Genome Sequencing Project database were analyzed to identify potential biological targets. For the first time, the ergosterol biosynthetic pathway in M. perniciosa was studied and the lanosterol 14α-demethylase gene (ERG11) that encodes the main enzyme of this pathway and is a target for fungicides was cloned, characterized molecularly and its phylogeny analyzed. ERG11 genomic DNA and cDNA were characterized and sequence analysis of the ERG11 protein identified highly conserved domains typical of this enzyme, such as SRS1, SRS4, EXXR and the heme-binding region (HBR). Comparison of the protein sequences and phylogenetic analysis revealed that the M. perniciosa enzyme was most closely related to that of Coprinopsis cinerea.37683-9

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

PERANCANGAN JAW CRUSHER PENGHANCUR BATU-BARA KAPASITAS 1 TON/JAM

Abstrak : Batu bara adalah sumber energi yang sudah lama digunakan terutama untuk pembangkit tenaga listrik, pembuatan baja, dan lain-lain, dengan naiknya harga minyak dunia yang berdampak terhadap naiknya harga minyak dalam negeri, batu bara menjadi sumber energi alternatif yang dapat digunakan sebagai bahan bakar rumah tangga dalam kemasan berupa briket. Sebelum batu bara digunakan, batu bara perlu di hancurkan terlebih dahulu menjadi bongkahan yang lebih kecil yang kemudian diproses menjadi serbuk batu bara dan dikemas dalam berbagai ukuran briket.Salah satu proses penghancuran batu bara adalah dengan menggunakan jaw crusher, dalam proses penghancuran ini bongkahan batu bara dimasukan diantara movable jaw yang digerakan oleh connecting rod dan fixed jaw yang sudah diatur gerakannya. Proses penghancuran batu bara terjadi karena adanya gesekan dan tekanan yang dilakukan oleh jaw gerak dan jaw tetap pada mesin tersebut.Berdasarkan hasil perancangan mesin jaw crusher kapasitas satu ton per jam diperoleh jika kecepatan jaw gerak adalah 16 rad/s, besarnya energi yang dibutuhkan untuk menghancurkan batu bara di daerah crushing zone adalah sebesar 257,6 joule dan gaya yang dibutuhkan untuk menghancurkan batu bara di daerah crushing zone adalah sebesar 3,85 kN Kata kunci: jaw crusher, batu bar

Potent Cardioprotective Effect of the 4-Anilinoquinazoline Derivative PD153035: Involvement of Mitochondrial KATP Channel Activation

Background: The aim of the present study was to evaluate the protective effects of the 4-anilinoquinazoline derivative PD153035 on cardiac ischemia/reperfusion and mitochondrial function. Methodology/Principal Findings: Perfused rat hearts and cardiac HL-1 cells were used to determine cardioprotective effects of PD153035. Isolated rat heart mitochondria were studied to uncover mechanisms of cardioprotection. Nanomolar doses of PD153035 strongly protect against heart and cardiomyocyte damage induced by ischemia/reperfusion and cyanide/aglycemia. PD153035 did not alter oxidative phosphorylation, nor directly prevent Ca(2+) induced mitochondrial membrane permeability transition. The protective effect of PD153035 on HL-1 cells was also independent of AKT phosphorylation state. Interestingly, PD153035 activated K(+) transport in isolated mitochondria, in a manner prevented by ATP and 5-hydroxydecanoate, inhibitors of mitochondrial ATP-sensitive K(+) channels (mitoK(ATP)). 5-Hydroxydecanoate also inhibited the cardioprotective effect of PD153035 in cardiac HL-1 cells, demonstrating that this protection is dependent on mitoK(ATP) activation. Conclusions/Significance: We conclude that PD153035 is a potent cardioprotective compound and acts in a mechanism involving mitoK(ATP) activation

Habitar a metrópole: os apartamentos quitinetes de Adolf Franz Heep

The restructuring of the housing market and the emergence of a new housing typology in Sao Paulo from the mid-1940s, the kitchenette apartment, coincided with changes in the parameters that guided disciplinary discourse and architectural practice in Brazil. Analyze the moment the new typology was formulated, their initial motivations and subsequent developments, allows not only to recover the trajectory of the German architect Adolf Franz Heep (1902-1978) as investigate the dialogue between European architectural avant-garde, the North-American experiences, the local architectural production and the local demands

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
