Internet e Cultura: um novo olhar, veloz e voraz
Wilson de Oliveira Souza
Revista Latina de Comunicación Social , 1999,
Abstract: Em cada piscadela que damos, um novo mundo enxergamos. Com a globaliza o, o modo de ver o mundo muda radicalmente, principalmente devido ao complexo ritmo ditado pelas rela es entre o meio ambiente e seus usuários. De forma sintetizada, podemos explicar que a globaliza o é resultado da terceira revolu o tecnológica (tecnologias ligadas à busca, processamento, difus o e transmiss o de informa es; inteligência artificial; engenharia genética), da forma o de áreas de livre comércio e blocos econ micos interligados (como o Mercosul, a Uni o Européia e o Nafta) e da crescente interliga o e interdependência dos mercados físicos e financeiros em escala planetária. Essa trinca é responsável pela altera o, principalmente, da nova forma de enxergarmos a cultura, aceitando que a mundializa o da cultura é um processo em curso, n o concluído ainda, na qual as formas culturais nacionais ou locais entram em contato rapidamente. Com isso, quedam as barreiras territoriais, for am as media es e criam, no dizer de Featherstone, a "terceira cultura", entendendo como "um conjunto de práticas, conhecimentos, conven es e estilos de vida que se desenvolvem de modo a se tornar cada vez mais independente dos Estados-Na o".

Journal of Sports Science and Medicine , 2011,
Abstract: This study investigated if there were acute interference effects of strength exercises on subsequent continuous and intermittent 5Km aerobic exercises. Eleven physically active males (23.1 ± 3.1 yrs, 1.75 ± 0.07 m, 70.5 ± 8.8 kg, and 58.2 ± 8.3 VO2max) performed the following experimental sessions: A) 5 sets of 5 RM on the leg press followed by a 5km run performed continuously (average velocity of the first and second ventilatory thresholds, vΔ50), B) 5 sets of 5 RM on the leg press followed by a 5km run performed intermittently (1 min run at the vVO2max : 1 min of rest); C) 2 sets of 15 RM on the leg press followed by a 5km continuous run; and D) 2 sets of 15 RM on the leg press followed by a 5km intermittent run. Heart rate, blood lactate concentration, rate of perceived exertion, and VO2 at the first and the fifth km were considered for statistical purposes. There were no significant effects of both strength bouts on any of the variables associated with endurance performance (p > 0.05). It seems that both maximum and strength endurance bouts do not acutely impair aerobic performance

Milton José Cardoso,Hélio Wilson Lemos de Carvalho,Ant?nio Carlos de Oliveira,Evanildes Menezes de Souza
Pesquisa Agropecuária Tropical , 2007, DOI: 10.5216/pat.v34i3.2310
Abstract: Foram avaliadas 24 cultivares de milho (21 variedades e três híbridos), em doze ambientes da Regi o Meio-Norte do Brasil (seis no Estado do Piauí e seis no Estado do Maranh o), nos anos agrícolas de 2000/2001 e 2001/2002, objetivando conhecer a adaptabilidade e a estabilidade fenotípica desses materiais para fins de recomenda o. Na análise conjunta de variancia, observaram-se diferen as entre os ambientes, entre as cultivares e inconsistência no comportamento das cultivares diante das oscila es ambientais. A produtividade média de gr os observada (5.934 kg.ha-1) mostra a potencialidade da regi o para o desenvolvimento da cultura do milho, colocando-a em condi es de competir com áreas de estados como Mato Grosso e Goiás. Todos os materiais avaliados, à exce o da variedade Sertanejo e do híbrido BRS 2110, mostraram alta estabilidade nos ambientes considerados. PALAVRAS-CHAVE: Intera o genótipo x ambiente; cultivar; Zea mays. Twenty-four maize cultivars (21 varieties and three hybrids) were evaluated in twelve environments of the Middle-North Region of Brazil (six in Piauí and six in Maranh o), in the 2000/2001 and 2001/2002 growing seasons, aiming to obtain regionally adapted materials. The experiments were carried out in a randomized complete block design with three replications. In the joint analysis of variance, differences were observed among environments and among cultivars, but no consistent cultivar responses to environmental variations were observed. The mean grain yield (5,934 kg.ha-1) indicates the region has a high potential for maize, able to compete with such states as Mato Grosso and Goias, traditional producers. All the cultivars tested, except the Sertanejo variety and the BRS 2110 hybrid, showed high stability in the environments. KEY-WORDS: Genotype x environment interaction; cultivar; Zea mays.

Abstract: Nesta pesquisa foram avaliados os teores dos metais tóxicos Cr, Cd, Ni e Pb, nos tecidos foliares, e a produ o de fitomassa verde da parte aérea em milho. As plantas foram cultivadas em vasos com substrato de solo (Latossolo Vermelho), fertilizadas com lodo de curtume nas doses: zero (testemunha), 113,1 mL (36 m3.ha-1), 226,2 mL (72 m3.ha-1), 452,4 mL (144 m3.ha-1) e 904,8 mL (288 m3.ha-1) por vaso, apenas com adubo químico, e com o adubo associado ao lodo de curtume. Os sete tratamentos foram aplicados em quatro repeti es, sob condi es de estufa, no período de agosto a novembro de 2003, em Santo Ant nio de Goiás, GO. O lodo de curtume foi incorporado ao solo vinte dias antes da semeadura e o adubo químico NPK 4-30-16 + Zn (1,256 g por vaso, ou 400 kg.ha-1) foi adicionado na opera o de semeadura do milho híbrido BR 205. Os teores médios dos metais tóxicos Cr, Cd, Ni e Pb, obtidos nas folhas das plantas, aos cinqüenta dias após a emergência, estiveram dentro dos limites toleráveis nestes tecidos. Os maiores teores de Cr (0,147 mg.dm-3) foram observados nos tratamentos com as maiores doses do lodo de curtume. Houve incremento da fitomassa verde da parte aérea das plantas com o aumento das doses do lodo. A adi o do lodo de curtume no substrato, em diferentes doses, como fonte de nutrientes para plantas de milho, apresentou resultados agron micos promissores. PALAVRAS-CHAVE: Nutri o de plantas; metais tóxicos; resíduo industrial; fitomassa. In this study, were measured levels of the toxic metals Cr, Cd, Ni, and Pb in leaf tissues, as well as the green matter yield of the aerial part of maize plants. The plants were grown in pots with a soil substrate (Oxisol), fertilized with tanning residue, in doses of zero (control), 113.1 mL (36 m3.ha-1), 226.2 mL (72 m3.ha-1), 452.4 mL (144 m3.ha-1), and 904.8 mL (288 m3.ha-1) per pot, with mineral fertilizer only, and with the combination of mineral fertilizer and tanning residue. The treatments were applied in four replications in greenhouse conditions, in the period of August to November 2003, in Santo Ant nio de Goiás, Brazil. The tanning residue was added to the soil twenty days before sowing and the mineral fertilizer NPK 4-30-16 + Zn (1.256 g per pot, or 400 kg.ha-1) was added during the sowing of the corn hybrid BR 205. The mean levels of toxic metals Cr, Cd, Ni, and Pb obtained in the leaves fifty days after emergence were below or within acceptable limits for these tissues. The largest levels of Cr (0.147 mg.dm-3) were usually observed in the treatments with the largest doses of the tanning residue. The

Abstract: this study was conducted to evaluate the use of ultrasound measurements to predict carcass composition of 115 steers (nellore, ? angus x nellore, ? simental x nellore, and canchim) with different frame sizes (small and large) and average initial body weight of 329 kg. after 120 days in a feedlot, animals were weighed followed by ultrasound measurements of rib eye area (ra) and fat thickness (ft). animals were slaughtered and measurements of carcass ra and ft, weights of hindquarter, forequarter, and commercial cuts, and determination of body composition were done. in addition, yields of carcass, commercial cuts, and hindquarter were calculated and no significant differences between frame sizes were found for these variables. ultrasound measurements were not precise predicting carcass muscle content and yields of commercial cuts in this trial. however, determination coefficients from regression equations of carcass composition using ultrasound were similar and sometimes higher (e.g. bone content) than those from regression equations of carcass composition, in which measurements were taken after slaughter. therefore, ultrasound measurements can be used to predict carcass composition of beef cattle for some variables.

Abstract: the objective of this study was to evaluate correlations between ultrasonography measurements and carcass traits of 115 steers (nellore, ? angus-nellore, ? simmental-nellore, and canchim) averaging 329 kg of initial body weight and two different finishing frame sizes (small and large). after 120 days in a feedlot, body weight, rib eye area (ra), and fat thickness (ft) were measured by ultrasound. following slaughter, carcass ra and ft measurements and weights of hindquarter, forequarter, and commercial cuts were all taken; body composition was also determined. yields of carcass, retail cuts, and hindquarter as well as ratios of ultrasound ra per 100 kg of body weight and ultrasound ra per 100 kg of carcass weight were calculated. data showed higher muscle deposition in ? simental-nellore and canchim and greater fat deposition in nellore while ? angus-nellore steers combined both characteristics. according to the results, ra was a good indicator of the proportion of muscle present in the carcass and selection for increasing carcass ra may decrease ft because of the negative correlation between ft and hindquarter percentage and ra. frame size did not affect carcass composition possibly due to the small variation between both groups. because correlations of measured and ultrasound ra and ft with carcass components yielded similar results, it was possible to validate ultrasound measurements to predict carcass composition of young bulls.

Abstract: objective: to evaluate the repair of congenital heart defects through minithoracotomies. methods: between january 1998 and march 2005, 98 patients underwent minithoracotomies for simple congenital heart defect repairs at our institution. all patients were female between the ages of 14 months and 16 years (mean 4.6) with weights ranging from 8 to 58 kg (mean 20). diagnoses included 78 cases of atrial septal defects (asd) (six with associated partial anomalous pulmonary venous drainage and four with pulmonary valve stenosis) and 20 cases of perimembranous ventricular septal defects (pvsd). all diagnoses were confirmed with an echocardiogram; therefore, cardiac catheterization was not required. a right submammary minithoracotomy was performed on 10 patients and a minithoracotomy with a partial median sternotomy was performed on 88 patients. results: all defects were corrected successfully with satisfactory exposure. cardiopulmonary bypass times ranged from 8 to 30 min (mean 10) and aortic clamping times ranged from 5 to 22 min (mean 12). all patients were extubated in the operating room and hospital stays ranged from 3 to 7 days (mean 5). there were no deaths during the operation or severe postoperative complications. no residual shunts were observed. conclusion: our study demonstrated that the minithoracotomy is a safe effective and technically viable alternative to a median sternotomy to correct selected simple congenital heart defects. the advantages of this approach include less trauma, partial or complete preservation of sternum continuity and integrity, and elimination of postoperative deformities such as pectus carinatum. the cosmetic outcome was superior to a median sternotomy.
