Abstract:

The aim of this study was to compare maturational stage and neuromuscular skills among soccer players and non-athletes, as well as to investigate the relationship between maturation and neuromuscular performance. Twenty five adolescent males (14.3 ± 0.45 years) participated in the study and were divided into two groups: soccer players (SP – n = 13, 14.1 ± 0.3 years, 58.9 ± 6.90 kg, 1.72 ± 0.04 m, 19.9 ± 1.7 kg·m2, 13.3% ± 4.3% fat) and non-athletes (NA – n = 12, 14.5 ± 0.5 years, 57.3 ± 6.9 kg, 1,67 ± 0.06 m, 20.6 ± 3.9 kg·m2, 14.0% ± 5.7% fat). The square test and 20 m speed test were used to assess agility and speed, respectively. The Tanner self-assessment of pubic hair and genitalia development test was used to estimate maturational development. The Shapiro Wilk test was used to verify the normality of samples. For any data not normally distributed, the non-parametric Mann Whitney test, as well as Kendall’s Tau correlation test, were used. The p-values determined for agility (p = 0.017) and speed (p = 0.054) indicated that agility was the only variable significantly different between SP and NA. The SP and NA groups showed no difference in the levels of maturation (p = 0.41), and maturational status was not significantly correlated with agility (r = 0.013) or speed (r = ?0.003). Conclusion: Individuals who practiced football had better results for the agility test than non-athletes, even with no difference between the degree of maturation and speed. There is a low correlation between level of maturity and agility or speed.

Abstract: the objective of this research was to determine changes in properties of a red-yellow podzolic soil, related to the gradual removal of the plow layer through simulated erosion and its effects on survival and growth of mimosa caesalpiniaefolia benth seedlings. in 1990, the experiment was conducted in a greenhouse of the universidade federal do ceará, in fortaleza, ce, brazil, in layers of 0-15, 5-20, 10-25, 15-30, 20-35 and 25-40 cm which were removed from a red-yellow podzolic profile and contained in plastic bags where seeds were planted and seedlings were grown for 85 days. higher values of clay percentage, available water, k and ca contents and of cec at deeper layers did not reduce the negative impact of erosion on the seedlings survival and growth since they were associated with increases of al saturation as well as with significant decreases in ph, organic matter, base saturation and n, p and mg contents in the soil. as depth of the removed layers increased, seedlings survival percentage, seedlings height, root and aerial part dry weights, as well as total dry biomass gradually decreased. compared to the 0-15 cm layer, at 25-40 cm those decreases were 16.8, 66.3, 67.1, 82.0, and 79.6%, respectively.

Abstract: O objetivo deste trabalho foi estudar mudan as nas propriedades de um Podzólico Vermelho-Amarelo relacionadas à remo o gradual de sua camada arável por meio de eros o simulada e seus efeitos na sobrevivência e crescimento de mudas de sabiá (Mimosa caesalpiniaefolia Benth). O experimento foi conduzido em casa de vegeta o, em 1990, no Departamento de Ciência do Solo, UFC, em Fortaleza, CE, em camadas do solo de 0-15, 5-20, 10-25, 15-30, 20-35 e 25-40 cm, as quais foram removidas e acondicionadas em sacos de plástico, onde as sementes foram plantadas e as mudas desenvolveram-se por 85 dias. Maiores valores de porcentagem de argila, de água disponível, de teores de K e Ca e da CTC determinados nas camadas mais profundas n o reduziram o impacto negativo da eros o na sobrevivência e crescimento das mudas, pois eles estavam associados a aumentos da satura o por Al, bem como a significativos decréscimos no pH, na matéria organica, na satura o por bases e nos teores de N, P e Mg no solo. à medida que a profundidade das camadas removidas aumentava, a porcentagem de sobrevivência, a altura, o peso seco das raízes e da parte aérea, bem como a biomassa seca total das plantas gradualmente decrescia; esses decréscimos foram de 16,8, 66,3, 67,1, 82,0 e 79,6%, respectivamente, na camada de 25-40 cm, em rela o aos dados da camada 0-15 cm.

Abstract: Background Early adverse experiences are associated with increased risk of developing psychiatric disorders, although little is known about the neurobiological mediators involved. The mechanisms by which early environmental influences may mediate vulnerability in the development of offspring await further investigation. The present study correlated the NGF, BDNF, IL-6 and cortisol levels of mothers with postpartum affective disorders (PPAD) with infant development. Methods A longitudinal study was performed with 152 pregnant women and their infants. Between 60 and 120 days after delivery, women were interviewed and provided biological samples for biochemical analysis, and the infants were examined for neurobiological-motor development. Results Overall, the mothers' history of affective disorders, PPAD and anxiety disorder were associated with infant motor development. Using an adjusted linear regression analysis, PPAD (p = 0.049), maternal anxiety disorder (p = 0.043), NGF level (p = 0.034) and infant cortisol level (p = 0.013) were associated with infant motor development. Using a factorial analysis of primary components, two components were retained. The psychological factor was characterized by a positive loading of a history of affective disorder, PPAD and anxiety disorder. For the biological factor, infant cortisol adhered negatively with infant motor development, but NGF was positively associated. The psychological factor had a negative association, but the biological factor had a positive association with infant motor development. Conclusions There are few studies that have focused on the relationship of biomarkers and infant neurodevelopment. Our study points that psychological and biological factors are associated with infant motor development, however the causal relationship between these factors is still to be defined.

Abstract: petroleum coke consumption and the increase of its production during the recent years are analyzed. the processing of heavy oils produces less light fractions and more heavy fractions, unbalancing the energetic matrix. to balance this, the petroleum industry usually raises the number of coking units, which consumes the heavy fractions and produces lighter fractions, generating coke as residue. the different forms of using coke generate pollutants that are regulated and controlled in different forms by different countries. it is concluded that, independent of the form in which petroleum coke is consumed, the users should consider the amount of pollutants emitted, mainly sulfur dioxide.

Abstract: Se analiza el consumo de coque de petróleo y el aumento de su producción en los últimos a os. El procesamiento de los petróleos pesados genera menos fracciones leves y más fracciones pesadas, desequilibrando la matriz energética. Para retornar el equilibrio, la industria petrolífera opta por aumentar el número de unidades de craqueamiento, que consumen las fracciones pesadas y producen fracciones más livianas, generando como residuo el coque. Los diversos usos del coque generan contaminantes cuya emisión es regulada en distinta forma en distintos países. Se concluye que, cualquiera que sea la ruta a seguir para la utilización del coque de petróleo, los consumidores deberán considerar los patrones de emisión de contaminantes, principalmente de dióxido de azufre.

Abstract: Obesity has become a major global health challenge and it is a risk factor for the development of several comorbid conditions. Additionally, obesity has considerable economic consequences. Obesity is a multifactorial condition that arises from independent influences of genetic and social-environmental factors on food intake and physical activity. It has been difficult to establish clear associations between weight status and the intake of single foods or food groups. In most people, the predisposition to obesity has a polygenic basis, which means that obesity will develop if an individual has several polygenic variants that increase body weight. The FTO gene was the first GWAS-identified obesity-susceptibility gene and since then other polygenic variants that are associated with BMI and dietary intake have also been identified. However, this is still an active area of research as more polygenetic variants await discovery.

On the Expansion and Fate of the Universe  [PDF]
Aldo Bonasera
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.311212
Abstract: The evolution of the universe from an initial dramatic event, the Big-Bang, is firmly established. Hubble’s law [1] (HL) connects the velocity of galactic objects and their relative distance: v(r) = Hr, where H is the Hubble constant. In this work we suggest that HL is not valid at large distances because of total energy conservation. We propose an expansion of the velocity in terms of their relative distance and produce a better fit to the available experimental data. Using a simple “dust” universe model, we can easily calculate under which conditions an (unstable) equilibrium state can be reached and we estimate the values of the matter present in the universe as well as the “dark energy”. Within the same formalism we can derive the “deceleration parameter”. We do not need to invoke any “dark energy”, its role being played by the kinetic correction. The resulting picture is that the universe might reach an unstable equilibrium state whose fate will be decided by fluctuations: either collapse or expand forever.
Processo decisório e práticas de gest?o: dirigindo a Secretaria da Saúde do Estado da Bahia, Brasil

Abstract: this case study is based on research performed by the bahia state health secretariat (sesab), aimed at analyzing management practices during the implementation of a state government administrative reform. the institutional agenda shows evidence of limited participation by civil society and technical and operational staff in problem selection and prioritization, resulting from a work process pressured by high-level executive government staff. decisions regarding "output" (projects, services, and activities) were made under the responsibility of subordinate operational levels and did not appear as issues in the institutional routine. concerns related to "input" (financial and human resources) consumed most of the high-level efforts, with internal and external negotiations and compromises to assure access to them. meanwhile the possible "outcome", namely public health status, represents the "occult subject" of the institutional discourse. information emerges in institutional disputes as a technical "power resource" in its medical, epidemiological, health, and administrative dimensions. the issue of government "representation" and allied interests is based on ideological dispositions and authoritarian practices, thus contradicting the need for management transparency and modernization.
