1. Characterization of a thermostable endoglucanase produced by Isoptericola variabilis sp. IDAH9
Abstract This study aimed to isolate and evaluate the cellulase activity of cellulolytic bacteria in hot springs of Dehloran, Ilam province, Iran. Water and sludge samples were collected from the hot springs and the bacterial enrichment was performed in a medium containing rice barn and carboxymethyl cellulose (CMC). The cultures were incubated at 50 °C in

2. Viscoelastic Behaviour Characterization of a Gap-graded Asphalt Mixture with SBS Polymer Modified Bitumen
A characterization of the linear thermo-viscoelastic behaviour of a gap-graded bituminous mixture with SBS-polymer modified bitumen and RAP aggregates is presented in this paper. A comparison was made, in terms of their viscoelastic behaviour, between this innovative mixture and two commonly used well-graded base-course French mixtures made with pure bitumen

3. Detection of human adenovirus, rotavirus and enterovirus in water samples collected on dairy farms from Tenente Portela, Northwest of Rio Grande do Sul, Brazil
Viral gastroenteritis and other waterborne diseases are a major concern for health in Brazil. A number of studies were conducted about the presence of viruses on water samples from Brazilian areas. However, the knowledge about the occurrence of viral contamination of drinking water sources in rural settings of the country is insufficient. On the present work

4. Free vibration analysis of an embarked rotating composite shaft using the hp-version of the FEM
This paper presents the study of the vibratory behavior of rotating composite shafts. The composite shaft contains isotropic rigid disks and is supported by bearings that are modeled as springs and viscous dampers. An hp-version of the Finite Element Method (FEM) is used to model the structure. A hierarchical finite element of beam type with six degrees of f

5. Dinâmica tridimensional de risers. / Tridimensional dynamics of risers.
Used in offshore oil exploitation risers are elements that connect the floating unit to the oil well on the seabed. They are exposed to the environmental conditions of the site where they are installed. Normally, the risers global behavior is divided in static and dynamic analyses. The static loads acting on the pipe are: weight, buoyancy and current load. T

7. A inserção do município de São Lourenço da Serra na Região Metropolitana de São Paulo: um estudo da geração de emprego e renda em uma área de proteção aos mananciais
The objective of this dissertation is to understand the path in the formation of the São Lourenço da Serra municipality, within the establishment of the Metropolitan Region of São Paulo (RMSP), administrative portion of São Paulo state, which binds the municipal. The research initially debates the historical constitution of São Lourenço da Serra, from

8. Anticoccidial, glycine and glutamine/glutamic acid use on diets with different threonine/lysine ratios for broiler chickens raised under health challenge / Uso de anticoccidiano, de glicina e de glutamina/ácido glutâmico em dietas com diferentes relações treonina /lisina para frangos de corte criados sob desafio sanitário
Two experiments with 4680 Cobb male broiler chickens were accomplished in order to evaluate different digestible threonine/digestible lysine ratios in rations with or without anticoccidial, glycine and glutamine/glutamic acid. In the first experiment three digestible threonine/ digestible lysine ratios were evaluated in rations supplemented or not with antic

9. Geometry, dynamics and fractals
Consider a collection of elastic wires folded according to a given pattern induced by a sequence of fractal plane curves. The folded wires can act as elastic springs. Therefore it is easy to build up a corresponding sequence of simple oscillators composed by the elastic springs clamped at one end and carrying a mass at the opposite end. The oscillation perio

10. O discurso constitucional da dignidade da pessoa humana: uma proposta de concretização do direito justo no pós-positivismo brasileiro
With an overrun of positivism, appears a methodological paradigm more compatible with the functioning of legal systems,reaffirming the privileged ties between the right and social morality. In this context, even before his legal recognition in the international declarations of law and the constitutions of various countries, the dignity of the human person is

11. Modelagem de lixiviação do herbicida picloram atraves de lisimetro de drenagem sob vegetação de Brachiaria decumbens / Modeling of picloram herbicide leaching in a lysimeter under Brachiaria decumbens vegetation
Picloram is one of the most used herbicides in the control of weeds in pastures areas, especially the ones of difficult eradication. Many are the stories of wells and springs contamination with herbicides residues as a result of its leaching in grounds. Due to the lack of knowledge and available data on the destination of the picloram in brazilian grounds, r

12. Influence of either operational speed and the pressure applied on compress wheels in the initial establishment of the maize crop under no-till system / Influência da velocidade operacional e da carga aplicada pelas rodas compactadoras sobre o estabelecimento inicial da cultura do milho em sistema de plantio direto
Since Brazil is one of the main maize producers throughout the world, this crop becomes an important target for research. To obtain the successful implantation of the crop, a good soil-seed contact should be promoted, besides to be careful about the good distribution of the plantlets. The no-till planting minimizes the undesirable effects from the preparatio
