Brazilian law considers areas around watercourses as Áreas de Preservação Permanente (APP) (Permanent Preservation Areas), which should be restored in case of degradation. This study aimed to present a plant recovery model based on Replacement Cost Method for an 11.7 hectares PPA, near the Water Treatment Station (WTS) of Tangará da Serra - MT. The research presents an applied nature, quantitative approach and structured script as a collection instrument, analyzed through the Replacement Cost Method (RCM), in order to estimate the recovery costs. The environmental diagnosis of the area showed the need for densified planting, at an estimated cost of R$ 24,492.00, with the greatest cost impact concentrated in implementation phase.

Currently, the SCC is already used in several countries and is considered a breakthrough in the building process of concrete structures, as it increases productivity, reduces the demand for labor, work in time of concreting and improves the quality of the concrete and the environment work. Innumerous investigations on SCC [,[,[,[ have been developing in order to know their behavior, improve their properties and applicability in different structural elements. This paper presents the implementation of the SCC in the execution of the base of the waters reservoir, in water treatment station.

Softening Process

A drinking water treatment plant has a typical configuration of parallel lanes to provide safe drinking water 24 h a day. A new approach for optimising the production of drinking water treatment plants is proposed. This approach is applied to the softening process step and shows promising results in terms of cost reduction by optimising the water distribution over several parallel reactors. The proposed scheme relies on optimal model-based control of a single softening reactor and the use of a bypass.

OBJECTIVE: to analyze the fluoride concentration in the public water supply at the area supplied by the Water Treatment Station of Bauru and classify the samples as acceptable or unacceptable according to the fluoride concentration. MATERIAL AND METHODS: samples were collected from 30 areas at two periods, October 2002 and March 2003. The fluoride concentration in the samples was determined in duplicate, using an ion sensitive electrode (Orion 9609) connected to a potentiometer (Procyon, model 720). Samples with fluoride concentration ranging from 0.55 to 0.84 mg F/L were considered acceptable, and those whose concentration was outside this range as unacceptable. Data were analyzed by descriptive statistics. RESULTS: the fluoride concentration of the water samples varied between 0.31 and 2.01 mg F/L. Nearly 56% of the samples were classified as acceptable. CONCLUSION: the variations in fluoride concentration at the area supplied by the Water Treatment Station reinforce the need of constant monitoring for maintenance of adequate fluoride levels in the public water supply.

The paper aims at describing a model-based approach to design automation logics for fault location and supply restoration in medium voltage distribution networks. The application of automation functions along medium voltage feeders and, in particular, the installation of protection devices in secondary substations mandates the design and the implementation of complex logics to coordinate the operations of this hardware in case of fault occurrences. This synchronization is realized with the exchange of IEC 61850 GOOSE messages, but the correct usage of this information must be implemented in each protection device through dedicated logics, which are not in the common out-of-the-box system configurations. To support the introduction and the design of these logics, an automata-based approach has been proposed and successfully demonstrated in a real environment in the European research project IDE4L. This formal methodology has been introduced to simplify the design phase and to standardize the logics implemented in the protection prototypes realized in the project. The same models have also been used in the implementation phase with a semi-automatic code generation procedure, considering as a target system the software programmable logic controllers (soft-PLCs), available on the protection devices. Based on the test results and the short time to set up the test bench, this approach proved to be a reliable and effective way to implement complex medium voltage (MV) automation logics such those needed in modern smart grids.

Aim. To design and deliver an activity-based costing model within a non-admitted prisoner healthcare setting. Method. Key phases from the NSW Health clinical redesign methodology were utilised: diagnostic, solution design and implementation. Results. The diagnostic phase utilised a range of strategies to identify issues requiring attention in the development of the costing model. The solution design phase conceptualised distinct ‘building blocks’ of activity and cost based on the speciality of clinicians providing care. These building blocks enabled the classification of activity and comparisons of costs between similar facilities. The implementation phase validated the model. Conclusions. The project generated an activity-based costing model based on actual activity performed, gained acceptability among clinicians and managers, and provided the basis for ongoing efficiency and benchmarking efforts.
