Abstract: the objective of this research was to study the effect of the following modifications on the traditional manufacturing process of prato cheese: use of milk concentrated by ultrafiltration (lcuf) up to a vcf=4:1; partial lcuf pre-fermentation; indirect curd cooking; on yield-(r), adjusted yield (raj) and fat (rgq) and protein (rpq) recovery on cheese, and comparison of the results with a standard cheese. three processings with five treatments each were realized, respectively: treatment 1-(t1), without ultrafiltration; treatment 2-(t2), ultrafiltration without lcuf pre-fermentation; treatment 3-(t3), 10% lcuf pre-fermentation; treatment 4-(t4), 20% lcuf pre-fermentation and direct curd heating; treatment 5-(t5), 20% lcuf pre-fermentation and the only one indirect curd heating. it was realized composition, yield, and component recovery for all five treatments, and the results statistically evaluated. treatments t2, t3, t4, and t5 presented lower values for r, raj and rgq, however, the pre-fermentation with indirect curd cooking presented a tendency of better values for rgq and raj. lower yields and rgs possibly resulted from the fibrous structure presented by these curds as well as due to the difficulty on cutting and handling them.

Abstract: O objetivo deste trabalho foi comparar os efeitos das seguintes modifica es no processo com o processo tradicional de fabrica o de queijo Prato: uso de leite concentrado por ultrafiltra o-(LCUF) até um FCV=4:1; pré-fermenta o de parte deste LCUF e aquecimento indireto da massa sobre o rendimento-(R), rendimento ajustado-(RAJ) e a recupera o de gordura-(RGq) e de proteína-(RPq) no queijo. Foram realizados 3 processamentos, com 5 tratamentos cada, respectivamente: Tratamento 1-(T1), sem ultrafiltra o; Tratamento 2-(T2), ultrafiltra o sem pré-fermenta o do LCUF; Tratamento 3-(T3), ultrafiltra o com pré-fermenta o de 10% do LCUF; Tratamento 4-(T4):, ultrafiltra o com pré-fermenta o de 20% do LCUF e com aquecimento direto da massa e Tratamento 5-(T5): ultrafiltra o com pré-fermenta o de 20% do LCUF e único com aquecimento indireto. Os resultados de composi o, rendimento e recupera o de componentes dos 5 tratamentos foram avaliados estatisticamente. Os tratamentos T2, T3, T4 e T5 apresentaram menores valores de R, RAJ e RGq e maiores valores de RPq, porém, a pré-fermenta o com cozimento indireto apresentou a tendência de melhores RGq e RAJ. Menores rendimentos e RGs possivelmente resultaram da estrutura fibrosa apresentada por esses coágulos, bem como pela dificuldade de corte e manipula o dos mesmos.

Abstract: The paper presents a structured model for improvement, based on the total quality principles of management, in order to serve as support for process improvement and cost reduction of organizations, within the broad aim of enhancing the value of products and services for customers. In cost literature, concepts dealing with improvements such as the kaizen cost, nonquality cost control, waste reduction and target-cost are presented. These concepts are based on the development of permanent improvements, both in the products and services. To apply the concepts of cost to improvement in such a way as to fulfill the criteria, it is necessary to work with a model that allows the organization of ideas and actions along the desired path. The proposed model consists of an improvement of the one formulated by Langley, Nolan, Nolan, Norman & Provost (1994) and has been tested in several organizations with positive results. Keywords: Cost reduction. Model for Improvement. Process management. O trabalho apresenta um modelo estruturado para melhoria, baseado nos princípios da gest o pela qualidade total, para apoiar a melhoria de processos e a redu o dos custos de organiza es, dentro do objetivo amplo de melhorar o valor de produtos e servi os para clientes. Na literatura sobre o assunto, s o apresentados conceitos que tratam das melhorias, tais como o custo-kaizen, controle dos custos da n o-qualidade, redu o de desperdícios e custo-alvo. Esses conceitos têm como base o desenvolvimento de melhorias permanentes, seja em produtos, seja em processos. Para aplicar criteriosamente os conceitos de custos para melhoria, é necessário operar com um modelo que possibilite organizar idéias e a es na dire o almejada. O modelo proposto consiste em um aperfei oamento daquele formulado por Langley et al. (1994), que foi testado e obteve resultados positivos em diversas organiza es. Palavras-chave: Redu o de custos. Modelo de melhoria. Gest o de processos.

Abstract: the contribution of amazonian and atlantic floras was analyzed in twelve localities in the cerrado biome. a total of 290 tree and shrub species were recorded in those localities. of these, 41.1% occurred only in cerrado and are probably endemic, and 58.9% also occurred in atlantic and/or amazonian forest. for non-endemic species the contribution of atlantic forest was greater (44.8%) than amazonian ones (1.4%), with the remaining 12.7% species found in both forest biomes. the proportions of species with centers of distribution in atlantic and amazonian forest showed a slight decrease toward the center of cerrado biome. for the former, the distance explained only 30% of variation in proportions by a polynomial model fit to the data, and for the latter a significant linear model explained 78% of variations. the flora of amazon forest and atlantic forest showed a segregation with altitude. the proportions of species with centers of distribution in the atlantic forest showed a slight increase with altitude, but a polynomial model explained only 18% of this variation. inversely, there was a linear relationship between the proportions of species with centers of distribution in amazonian forest and altitude that explained 31% of variation. the differences in contribution patterns of the atlantic and amazonian forest flora to the cerrado physiognomy is discussed with respect to climatic changes during the quaternary and to differences in plant species tolerance to fire and low temperature in the cerrado biome.

Abstract: Since 1932, the Curu River watershed has received assistance from the Federal and the State government. It stands out among other Ceara watersheds and has been the first to implement the irrigated perimeter system (1975) and also to organise a Watershed Committee (1996). Nowadays, it has serious environmental problems related to the effects of inadequate use of the natural resources. Thus, the objective of this investigation was to analyse physico-chemical and microbiological parameters in sections of rivers of the Curu basin, using Resolution no 357 (CONSELHO NACIONAL DE MEIO AMBIENTE, 2005) as the main reference. In the field, the main potential factors in the degradation of surface waters in the watershed were identified through the check list method, and 15 sampling stations in river sections were defined and located geographically. Five collections of water samples were taken and analyzed in the laboratory over a period of one year (feb./2003 to mar./2004). During this study, it was observed that the degradation of water resources increases with economic and demographic development of the Curu basin, because of the devastation of the original vegetation and the contamination of the surface water with draining from urban and rural activities. = Desde 1932, a bacia hidrográfica do rio Curu vem sendo alvo de interven es governamentais tanto em ambito federal como estadual. Destaca-se dentre as outras bacias do estado do Ceará por ter sido a primeira a implantar o sistema de perímetros irrigados, em 1975, bem como a primeira a organizar um Comitê de Bacia Hidrográfica, em 1996. Encontra-se atualmente com sérios problemas ambientais relacionados aos efeitos da utiliza o inadequada dos recursos naturais. A presente pesquisa teve por objetivo analisar a qualidade das águas superficiais do rio Curu e de seus principais reservatórios, considerando-se alguns parametros físicos, químicos e o teor de coliformes termotolerantes, segundo a Resolu o no 357 (CONSELHO NACIONAL DE MEIO AMBIENTE, 2005). Em campo foram identificados os principais fatores potenciais de degrada o dos recursos hídricos superficiais da bacia através do método “listagem de controle” (check list). Foram definidos egeorreferenciados 15 pontos de amostragem, envolvendo se es de rios e principais reservatórios, realizando-se cinco coletas de água com análises laboratoriais no período de um ano (fev./2003 a mar./2004). O estudo revelou que o crescimento econ mico e demográfico da bacia vêm provocando a degrada o dos recursos hídricos através do desmatamento da vegeta o original, da ocupa
