Subsídios para implantação de trincheiras de infiltração na área urbana de Rio Claro/SP

The purpose of this work is to study the theme “infiltration trenches” in some of its main aspects, such as sizing methods and parameters related to this, in order to subsidize the installation of these structures in the urban area of Rio Claro/SP. For purposes of sizing, the “rain-envelope method” was used for its simplicity and direct application from the local characterization data and the IDF (intensity-duration-frequency) curve data. The method bases on the determination of the tributary volume of input and output device. The curve of values accumulated over time of the volumes tributaries to the device, which is built on the flow rates obtained from the local IDF curve, is compared with the value curve of his effluent volumes determined from the flow characteristics obtained from the infiltration soil. The maximum difference between the curves is the volume sizing. Five locations were chosen in the urban area of Rio Claro for implementation of these devices, considering the soil type, hydraulic conductivity of each area and lot size according to the Master Plan of Rio Claro. This work also presented an estimated reduction of the runoff in urban lots by using infiltration trenches.

Valoração do tratamento de efluentes de um curtume

During the production process of leather a lot of water is used. In addition, companies such as tanneries have high pollution potential. The effluent that is not properly treated , and it is irregularly released in water bodies can cause negative impacts to the environment and generate fines. The aim of this paper is to present the importance of environmental valuation in the effluent treatment system of a tannery, in order to add social and economic development with preservation of environmental quality. A valuation of inputs and outputs of the effluent treatment process from Tannery Bull in Presidente Prudente was made, as well as a proposal to improve the treatment and its valuation. Many of these industries do not account the costs from the effluent treatment and end up spending what could have been avoided. The management of environmental costs promotes sustainable development. Thus, we can conclude that, if there were better control and also an improved management of the tannery, the proposed treatment would bring economic improvement to the company and specially it would not cause much impact on the environment, including improving the quality of life in the region

Exploring different approaches for music genre classification

In this letter, we present different approaches for music genre classification. The proposed techniques, which are composed of a feature extraction stage followed by a classification procedure, explore both the variations of parameters used as input and the classifier architecture. Tests were carried out with three styles of music, namely blues, classical, and lounge, which are considered informally by some musicians as being “big dividers” among music genres, showing the efficacy of the proposed algorithms and establishing a relationship between the relevance of each set of parameters for each music style and each classifier. In contrast to other works, entropies and fractal dimensions are the features adopted for the classifications.

Action of the salivary microorganisms having sorbitol as substratum

Microorganisms living in the saliva are able to ferment some sweetener types and to promote the fall of pH that has its critical point around 5.5; in this situation, they equal the input and the calcium output in the processes of remineralization and demineralization. For iteration of the three essential factors to the installation of the dental caries (microorganism, host and diet) suggested the accomplishment of a work that involved one of these factors. This work aims to study this issue, through the indication of substitute sweetener of the saccharose, whenever possible, it solved to evaluate pH of the saliva, exposed to sorbitol.

Three-body Faddeev calculation for 11Li with separable potentials

The halo nucleus 11Li is treated as a three-body system consisting of an inert core of 9Li plus two valence neutrons. The Faddeev equations are solved using separable potentials to describe the two-body interactions, corresponding in the n-9Li subsystem to a p1/2 resonance plus a virtual s-wave state. The experimental 11Li energy is taken as input and the 9Li transverse momentum distribution in 11Li is studied. [S0556-2813(99)01703-3].

Evolução antropométrica de crianças hospitalizadas com diarréia persistente e desnutrição grave, submetidas a suporte nutricional

In order to estimate the nutritional rehabilitation (NR) during admission of malnourished children with persistent diarrhea (PD) receiving standardized nutritional support (NS), we prospectively evaluated the weight, height, head circumference and arm measurements (AM) of 20 children, 19 below 1 year, admitted to the ward with weigh/age -2.89 to -5.21 standard deviation. Four infants comprised the death group (DG) and 16 survived (SG). The SG was separated, according to initial weight behavior, into weight gain (WG) or weight loss (WL). Compared to SG at admission, DG only had lower AM and more metabolic-infectious alterations (p<05). The survivors presented NR but this was evident for WL only when considering the minimum weight. DG received less calories than SG and weight loss during the pre-death period was higher than for WL (p<05). It was concluded that very altered AM, severe metabolic-infectious insults, low caloric input and high weight loss velocity are associated to bad prognosis; severely malnourished infants with PD began NR during hospitalization while receiving adequate NS, but minimum weight must be considered for this evaluation; AM must be obtained at admission, due to its prognostic value, and adequate NS as well as anthropometric follow-up during the hospital stay are essential.
