A avaliação da qualidade da água em microbacias sob diferentes usos pode ser feita pelo uso de técnicas estatísticas multivariadas. Em Guaíra (SP), foi realizado o monitoramento da qualidade da água em uma microbacia de uso agrícola e urbano com 9600 ha, no período de jun/95 a jun/96. Coletaram-se amostras de água a cada 21 dias em 5 pontos, sendo determinadas 10 variáveis (fósforo total e dissolvido, pH, oxigênio dissolvido, amônia, nitrato, condutividade elétrica, turbidez, sólidos totais em suspensão ...

The separation of binary mixtures which form azeotropes is not possible through conventional distillation and they are usually separated by extractive or azeotropic distillation. The optimization of extractive distillation columns is usually performed using a process simulator; however, normally, the result is only obtained after several simulations and the simultaneous analysis of several graphs. This paper sets out to present a systematic procedure, using a process simulator (Aspen Plus®), in order ...

Esophageal trauma is considered one of the most severe lesions of the digestive tract. There is still much controversy in choosing the best treatment for cases of esophageal perforation since that decision involves many variables. The readiness of medical care, the patient's clinical status, the local conditions of the perforated segment, and the severity of the associated injuries must be considered for the most adequate therapeutic choice.To demonstrate and to analyze the results of urgent esophagectomy ...

Composting is recognized as one of the most cost-effective and environmentally sound alternatives for organic waste recycling. Long-composted wastes have the potential to substitute for inorganic fertilizers. We investigated the effect of tannery sludge compost (TSC) amendment rates on microbial biomass and activity in Brazilian soils. The soils (sandy and clayey soils) were amended with TSC at rates of 0 (control), 7.5, 15, 30 and 60 Mg ha−1 (equivalent to 0, 0.3, 0.6, 1.2 and 2.4 g per 100 g of soil, ...

Alumina production through Bayer Process is limited by the instability of soluble sodium aluminate in the supersaturated solutions used by the alumina refineries. The precipitation of aluminum hydrate can occur in equipment not designed for this purpose, causing significant loss of production. The stabilization of sodium aluminate in solution results in a decrease of the supersaturation, reducing the driving force for precipitation of aluminum hydrate. The reduction of supersaturation can be achieved ...

The process of drying/curing automobile painting is characterized as one of the main stages in automobile assembly. To guarantee the final painting quality, optimal operating conditions (mainly the temperature profile in the painting chamber) must be satisfied, and they are empirically defined in most cases. The availability of a mathematical model in transient regime enables the prediction of the drying/curing process behavior and consequences of possible operational changes on the final quality ...

O coeficiente de recessão (α) indica a taxa de produção do fluxo de base, que representa a porção da vazão de um rio mantida pela restituição de águas subterrâneas. Ele pode ser obtido através da análise de hidrogramas. Esse coeficiente possibilita o cálculo de parâmetros importantes, como a transmissividade de aquíferos, as reservas renováveis de água subterrânea e as vazões mínimas em canais de drenagem, que, usualmente, são obtidas através de outros índices hidrológicos, como o Q7,10, muito empregado ...

The disorderly machinery traffic has been one of the main causes of soil physical degradation in sugarcane fields. In this sense, the adoption of strategies for machinery traffic control has been a viable alternative to reduce the risk of soil compaction and minimize physical restrictions to plant growth. However, the impact of traffic control on soil physical properties is still unknown in sugarcane fields. In this study, we investigated the impacts of machinery traffic control on soil physical ...

Abstract This article describes the design of a control structure architecture for an industrial polyvinyl chloride (PVC) dryer, currently operating at Braskem Company (Marechal Deodoro, Alagoas, Brazil). The underlying motivation is to search for a control configuration that leads to optimal economic operation, while promptly rejecting disturbances at lower layers in the control hierarchy. We start by optimizing a nonlinear model of the process with respect to reducing energy consumption as a criterion ...

A case study based on a real process, the purification of 1,2-dichloroethane (DCE) in a high-purity distillation column, is presented. This column has the highest steam flow rate in any vinyl chloride monomer (VCM) plant. A configuration using a vapor ...

We evaluated the contribution of tumor necrosis factor-α receptor 1 (TNFR1) to ethanol-induced hypertension and vascular oxidative stress and the possible role of perivascular adipose tissue (PVAT) in such responses. Male C57BL/6 wild-type (WT) or TNFR1-deficient mice (TNFR1-/-) were treated with ethanol (20% vol/vol) for 12 weeks. Ethanol induced an increase in blood pressure in WT mice and TNFR1-/- at 4 and 5 weeks of treatment, respectively. Treatment with ethanol increased tumor necrosis factor-α ...

Distillation is one of the most studied processes in the control literature because of its importance as a separation process. However, little attention has been paid to the dynamics and control of the simultaneous changes in the feed and product specifications. In this study, it is proposed an intelligent control system based on artificial neural network for the extractive process to obtain anhydrous ethanol using ethylene glycol as a solvent. The study considered the changes in the azeotropic ...

Abstract An engineering application case study on a two‐fluid flow model for the control of industrial drying operations is reported. The mathematical model of this process was numerically solved by a computer code developed in FORTRAN language and was validated through data taken from PVC drying performed in an industrial continuous fluidized‐bed dryer. The predicted steady‐state outlet temperature and PVC moisture content values agree with the real data observed on the industrial plant. This model ...

Juvenile hormone analogs (JHA) are known to interfere with growth and biosynthesis of insects with potential for insecticide action. However, there has been comparatively few data on morphological effects of JHA on insect organs. To determine pyriproxyfen effects on Aedes aegypti larvae, we conducted toxicity, behavioral bioassays and assessed ultrastructural effects of pyriproxyfen on midgut cells. A. aegypti larvae were exposed in aqueous solution of pyriproxyfen LC50 concentrations and evaluated ...
