25. Exploring alternatives for the construction of neural spatial interaction models / Explorando alternativas para construção de modelos neurais de interação espacial
The rapid growth of Brazilian cities, without a previous planning of their expansion (including land use and occupation), causes many inconveniences for the population related to their transportation, as they must cover longer distances. This asks for an understanding of the city areas limits, the services currently offered to the community in each area, and

26. Estudo da desidratação osmotica com aditivos e do acondicionamento sob atmosfera modificada de pedaços de mamão formosa / Study of osmotic dehydration with additives and of the packaging under modified atmosphere of Formosa papaya pieces.
Modern life style, allied to an interest for a healthy diet, has been causing a market demand for fresh-like foods, ready for consumption and convenience. In response to this demand the food industry promoted the development of mild processes and technologies, aiming to maintain product final quality and increase its resistance to degradation. Papayas from t

27. Enhancement of the performance of an anaerobic sequencing batch reactor treating low-strength wastewater through implementation of a variable stirring rate program
This work focuses on enhancement of the performance of an anaerobic sequencing batch reactor with a six-vertical-blade-disk-turbine impeller, containing granulated biomass treating low-strength synthetic wastewater, through a study of the feasibility of implementing a variable stirring rate program. The reactor was operated at 30ºC and a six-hour cycle was

28. Formation of soluble microbial products (SMP) in anaerobic reactors during stress conditions
Anaerobic wastewater treatment has many advantages over aerobic treatment, however, one factor that limits its application is the relatively high concentration of organic material in the effluent. Characterization of both aerobic and anaerobic effluents has shown that the majority of the residual chemical oxygen demand (COD) is due to soluble microbial produ

29. Evaluation of the departure of stream beds cultivated in the residuary water treatment of the banana candy processing. / Avaliação da partida de leitos cultivados no tratamento de agua residuaria do processamento de doce de banana.
The purpose of this research was to test the performance of a constructed macrophytes wetland in the reduction of organic material and solids clearance of wastewater characteristic of the banana candy processing. There are few reports about the use of constructed wetlands in the treatment of wastewater from food processing and none of them refers to its kind

30. O problema do corte bidimensional : uma abordagem utilizando o metodo de geração de colunas
In this work we describe an experimental study of optimization techniques to generate efficient results for the two-dimensional cutting stock problem which can be defined as follows: given a finite number n of rectangular items of width li, length Ci and demand di, to be cut from larger rectangles with dimensions LxC, find cutting pattems which attend the de

31. APPLICATION OF FUZZY LOGIC TO THE MUHLBAUER MODEL FOR PIPELINE RISK ANALYSIS / APLICAÇÃO DA LÓGICA NEBULOSA AO MODELO MUHLBAUER PARA ANÁLISE DE RISCO EM DUTOS
W. Kent Muhlbauer made a detailed identification of approximately 300 different conditions that influence in the evaluation of the Risk in a pipeline, so, He proposed a punctuation system that is known as the method of Muhlbauer. Muhlbauer`s method evaluates the several variables that influence in the pipeline Risk by the attribution of quantitative values.

32. Avaliação de arranjos cogeradores em siderurgicas brasileiras com auxilio de simulação computacional
This work deals with technical and economical assessment of cogeneration schemes ir Brazilian steel industries based on cogeneration plants previously installed in Brazil and abroad In particular, cogeneration schemes that can cover 100 per cent of eletric demand and eventuall) produce surplus eletricity, are considered. Computational simulation is used as a

33. Escolarização e reabilitação de portadores de deficiencia visual : percepção de escolares e ações de reabilitação
A transversal descriptive study was performed regarding the characteristics of visually impaired school students and their perceptions in relation to their own schooling progress and rehabilitation. The rehabilitation activities in the municipality of Campinas, São Paulo were also studied. The population was composed of visually impaired school students of

34. Obtenção de galio a partir de rejeitos industriais
The gallium international demand has been increasing in the last few years, tending to grow, due to its application in assembling state of art eletronic devices, used in telecomunication, computers, etc. This element is found, in nature, very spread and, at low concentration. Among many methods used to concentrate it, there is the carbonatation process of th

35. Comparative inactivation of poliovirus type 3 and MS2 coliphage in demand-free phosphate buffer by using ozone.
MS2 coliphage (ATCC 15597-B1) has been proposed by the U.S. Environmental Protection Agency as a surrogate for enteric viruses to determine the engineering requirements of chemical disinfection systems on the basis of previous experience with chlorine. The objective of this study was to determine whether MS2 coliphage was a suitable indicator for the inactiv

36. Effect of turbidity on chlorination efficiency and bacterial persistence in drinking water.
To define interrelationships between elevated turbidities and the efficiency of chlorination in drinking water, experiments were performed to measure bacterial survival, chlorine demand, and interference with microbiological determinations. Experiments were conducted on the surface water supplies for communities which practice chlorination as the only treatm
