Efeito da suplementação com óleo de canola sobre a qualidade da manteiga e muçarela

A sociedade está cada vez mais exigente com relação à qualidade dos produtos consumidos e se preocupa com os benefícios para a saúde. Neste contexto, objetivou-se avaliar o efeito da inclusão de níveis de óleo de canola na dieta de vacas sobre amanteiga e muçarela, buscando produtos mais saudáveis para o consumo humano. Foram utilizadas 18 vacas Holandesas, em estágio intermediário de lactação, com produção média de 22 (± 4) Kg de leite/ dia, as quais foram distribuídas em dois quadrados latinos 3x3 contemporâneos e receberam as dietas experimentais: T1- Controle (0% de inclusão de óleo); T2- 3% de inclusão de óleo de canola e T3- 6% de inclusão de óleo de canola. O perfil lipídico foi determinado através de cromatografia gasosa, além da avaliação de qualidade nutricional, realizada através de equações utilizando os ácidos graxos obtidos no perfil lipídico, análises físico-químicas determinadas pela metodologia do Instituto Adolfo Lutz e análises microbiológicas. Houveram problemas durante processamento do leite, gerando alterações de tecnologia de fabricação do produto manteiga, obtendo-se outro produto, o creme de leite, ao invés de manteiga, além de prejuízos na qualidade microbiológicas do creme de leite e muçarela. A inclusão de óleo de canola na dieta em lactação reduziu quadraticamente os ácidos graxos de cadeia curta e proporcionou aumento quadrático dos ácidos graxos de cadeia longa, dos ácidos graxos insaturados e ácidos graxos monoinsaturados na muçarela. A relação ácidos graxos saturados/ ácidos graxos insaturados (AGS/ AGI) e a relação ômega-6/ômega-3, assim como os índices de aterogenicidade e trombogenicidade, na muçarela, reduziram linearmente 25,68%, 31,35%; 32,12% e 21,78%, respectivamente, quando comparando T1 e T3. No creme de leite, houve redução linear dos ácidos graxos de cadeia curta e média, bem como, os ácidos graxos saturados e a relação ácidos graxos saturados/ ácidos graxos insaturados (AGS/ AGI) em 41,07%; 23,82%; 15,91% e 35,59%, respectivamente, enquanto os ácidos graxos de cadeia longa, ácidos graxos insaturados e ácidos graxos monoinsaturados aumentaram linearmente 41,40%; 28,24% e 32,07%, nesta ordem, quando comparando T1 com T3. Os índices de aterogenicidade e trombogenicidade reduziram de forma linear, enquanto o índice h/H (razão ácidos graxos hipocolesterolêmicos e hipercolesterolêmicos) aumentou linearmente. A composição físico-química de ambos derivados e o rendimento da muçarela não apresentaram efeito significativo com a inclusão do óleo de canola, exceto a proteína bruta da muçarela que apresentou aumento linear e a gordura do creme de leite que apresentou efeito quadrático. As análises microbiológicas mostram contagens muito elevadas de microrganismos, sugerindo que os produtos não apresentam qualidade microbiológica, decorrente da ausência do processo de pasteurização do creme e da baixa eficiência do tratamento térmico aplicado ao leite destinado a produção da muçarela. Conclui-se que a adição de óleo de canola na dieta de vacas lactantes proporciona muçarela e creme de leite mais saudáveis para o consumo humano, pois apresentaram perfil lipídico mais rico em ácidos graxos insaturados, além da série ômega-3 e ácido oleico, entretanto, devido a problemas de processamento, estes produtos obtidos, não estão aptos ao consumo devido à ausência de qualidade microbiológica.

Distortion of self-image: risk factor for obesity in children and teenagers

Introduction: Self-image is important in the behaviour and lifestyle of children and adolescents. Analysing the self-image they have and the factors that might influence their distortion, can be used to prevent problems of obesity and anorexia. The main objective of present publication was to analyse the risk factors that may contribute to self-image distortion. Material and Methods: A descriptive survey study was conducted among 659 children and adolescents in two social classes (low and medium-high), measuring height and weight, calculating BMI percentile for age and gender. Body image and self-perception were registered. Results: The percentage of overweight-obesity is higher in scholars (41.8% boys, 28.7% girls) than in adolescents (30.1% and 22.2% respectively), with no difference between socioeconomic classes. The multinomial logistic regression analysis gives a risk of believing thinner higher (p=0.000) among boys OR=2.9(95%CI:1.43-3.37), school (p=0.000) OR=2.42(95%CI:1.56-3.76) and much lower (p=0.000) between normally nourished OR=0.08(95%CI:0.05-0.13), with no differences according to socioeconomic status. The risk of believing fatter is lower (p=0.000) between boys OR=0.28(95%CI:0.14-0.57), school(p=0.072) OR=0.54(95%CI:0.27-1.6), and much higher among underweight (p=0.000) OR=9x108(95% CI:4x108-19x108). Conclusions: Are risk factors of believing thinner: males, being in a group of schoolchildren and overweight-obesity. Conversely, are risk factors of believing fatter: females, teen and above all, be thin.

Architectural Technology and the BIM Acronym 3: Getting to Grips with BIM

Among Small and Medium Sized Enterprises (SMEs) in particular, the UK Government’s ambitions regarding BIM uptake and diffusion across the construction sector may be tempered by a realpolitik shaped in part by interactions between the industry, Higher Education (HE) and professional practice. That premise also has a global perspective. Building on the previous 2 papers, Architectural technology and the BIM Acronym 1 and 2, this third iteration is a synthesis of research and investigations carried out over a number of years directly related to the practical implementation of BIM and its impact upon BE SMEs. First challenges, risks and potential benefits for SMEs and micros in facing up to the necessity to engage with digital tools in a competitive and volatile marketplace are discussed including tailoring BIM to suit business models, and filtering out achievable BIM outcomes from generic and bespoke aspects of practice. Second the focus is on setting up and managing teams engaging with BIM scenarios, including the role of clients; addresses a range of paradigms including lonely BIM and collaborative working. The significance of taking a whole life view with BIM is investigated including embedding soft landings principles into project planning and realisation. Thirdly procedures for setting up and managing common data environments are identified and the value of achieving smooth information flow is addressed. The overall objective of this paper is to provide SMEs with a practical strategy to develop a toolkit to BIM implementation.

We all stand together: Using cluster associations to create worldwide presence for SMEs

This paper examines the potential for cluster associations to act globally on behalf of small and medium-sized enterprises (SMEs) utilising networked internet-based capabilities to trade globally. The slow up-take of such new technology and the problems involved is also becoming of increased interest to policymakers. This paper argues that cluster associations with low power-dependence and decentralised structures are better able to provide the necessary support that networks of SMEs require to utilise the technology.

Effect of environment and genotype on bread-making quality of spring-sown spring wheat cultivars in China

Improvement of end-use quality in bread wheat depends on a thorough understanding of current wheat quality and the influences of genotype (G), environment (E), and genotype by environment interaction (G x E) on quality traits. Thirty-nine spring-sown spring wheat (SSSW) cultivars and advanced lines from China were grown in four agro-ecological zones comprising seven locations during the 1998 and 1999 cropping seasons. Data on 12 major bread-making quality traits were used to investigate the effect of G, E, and G x E on these traits. Wide range variability for protein quantity and quality, starch quality parameters and milling quality in Chinese SSSW was observed. Genotype and environment were found to significantly influence all quality parameters as major effects. Kernel hardness, flour yield, Zeleny sedimentation value and mixograph properties were mainly influenced by the genetic variance components, while thousand kernel weight, test weight, and falling number were mostly influenced by the environmental variance components. Genotype, environment, and their interaction had important effects on test weight, mixing development time and RVA parameters. Cultivars originating from Zone VI (northeast) generally expressed high kernel hardness, good starch quality, but poor milling and medium to weak mixograph performance; those from Zone VII (north) medium to good gluten and starch quality, but low milling quality; those from Zone VIII (central northwest) medium milling and starch quality, and medium to strong mixograph performance; those from Zone IX (western/southwestern Qinghai-Tibetan Plateau) medium milling quality, but poor gluten strength and starch parameters; and those from Zone X (northwest) high milling quality, strong mixograph properties, but low protein content. Samples from Harbin are characterized by good gluten and starch quality, but medium to poor milling quality; those from Hongxinglong by strong mixograph properties, medium to high milling quality, but medium to poor starch quality and medium to low protein content; those from Hohhot by good gluten but poor milling quality; those from Linhe by weak gluten quality, medium to poor milling quality; those from Lanzhou by poor bread-making and starch quality; those from Yongning by acceptable bread-making and starch quality and good milling quality; and those from Urumqi by good milling quality, medium gluten quality and good starch pasting parameters. Our findings suggest that Chinese SSSW quality could be greatly enhanced through genetic improvement for targeted well-characterized production environments.

Milling quality and protein properties of autumn-sown Chinese wheats evaluated through multi-location trials

Eight milling quality and protein properties of autumn-sown Chinese wheats were investigated using 59 cultivars and advanced lines grown in 14 locations in China from 1995 to 1998. Wide ranges of variability for all traits were observed across genotypes and locations. Genotype, location, year, and their interactions all significantly influenced most of the quality parameters. Kernel hardness, Zeleny sedimentation value, and mixograph development time were predominantly influenced by the effects of genotype. Genotype, location and genotype x location interaction were all important sources of variation for thousand kernel weight, test weight, protein content, and falling number, whereas genotype x location interaction had the largest effect on flour yield. Most of the genotypes were characterized by weak gluten strength with Zeleny sedimentation values less than 40 ml and mixograph development time shorter than 3 min. Eight groups of genotypes were recognized based on the average quality performance, grain hardness and gluten strength were the two parameters that determined the grouping, with contributions from protein content. Genotypes such as Zhongyou 16 and Annong 8903 displayed good milling quality, high grain hardness, protein content and strong gluten strength with high sedimentation value and long mixograph development time. Genotypes such as Lumai 15 and Yumai 18 were characterized by low grain hardness, protein content and weak gluten strength. Genotypes such as Yannong 15 and Chuanmai 24 were characterized by strong gluten strength with high sedimentation value and long mixograph development time, but low grain hardness and protein content lower than 12.3%. Genotypes such as Jingdong 6 and Xi'an 8 had weak gluten strength, but with high grain hardness and protein content higher than 12.2%. Five groups of locations were identified, and protein content and gluten strength were the two parameters that determined the grouping. Beijing, Shijiazhuang, Nanyang, Zhumadian and Nanjing produced wheats with medium to strong gluten strength and medium protein content, although there was still a large variation for most of the traits investigated between the locations. Wheat produced in Yantai was characterized by strong gluten strength, but with low protein content. Jinan, Anyang and Linfen locations produced wheats with medium to weak gluten strength and medium to high protein content. Wheats produced in Yangling, Zhenzhou, and Chengdu were characterized by weak gluten strength with medium to low protein content, whereas wheats produced in Xuzhou and Wuhan were characterized by weak gluten strength with low protein content. Industrial grain quality could be substantially improved through integrating knowledge of geographic genotype distribution with key location variables that affected end-use quality.

Biodegradation of the cyanobacterial toxin microcystin LR in natural water and biologically active slow sand filters

A bacterium (MJ-PV) previously demonstrated to degrade the cyanobacterial toxin microcystin LR, was investigated for bioremediation applications in natural water microcosms and biologically active slow sand filters. Enhanced degradation of microcystin LR was observed with inoculated (1 x 10(6) cell/mL) treatments of river water dosed with microcystin LR (> 80% degradation within 2 days) compared to uninoculated controls. Inoculation of MJ-PV at lower concentrations (1 x 10(2)-1 x 10(5)cells/mL) also demonstrated enhanced microcystin LR degradation over control treatments. Polymerase chain reactions (PCR) specifically targeting amplification of 16S rDNA of MJ-PV and the gene responsible for initial degradation of microcystin LR (mlrA) were successfully applied to monitor the presence of the bacterium in experimental trials. No amplified products indicative of an endemic MJ-PV population were observed in uninoculated treatments indicating other bacterial strains were active in degradation of microcystin LR, Pilot scale biologically active slow sand filters demonstrated degradation of microcystin LR irrespective of MJ-PV bacterial inoculation. PCR analysis detected the MJ-PV population at all locations within the sand filters where microcystin degradation was measured. Despite not observing enhanced degradation of microcystin LR in inoculated columns compared to uninoculated column, these studies demonstrate the effectiveness of a low-technology water treatment system like biologically active slow sand filters for removal of microcystins from reticulated water supplies.

ASSOCIATIVISMO EMPRESARIAL ENTRE MICRO E PEQUENAS EMPRESAS: A EXPERIÊNCIA DO GRANDE ABC COM O PROJETO EMPREENDER (SEBRAE)

O associativismo empresarial aparece como forma de desenvolvimento regional, seja este econômico, social ou cultural, e é grande aliado para o surgimento e crescimento das micro e pequenas empresas. É um tema já vivenciado e estudado por vários países do mundo, entre eles europeus e especificamente italianos, mas ainda pouco estudado e conhecido no Brasil. A presente pesquisa objetivou analisar o associativismo empresarial entre micro e pequenas empresas (MPEs) na região do Grande ABC (GABC) pelo Projeto Empreender (SEBRAE) relacionando seus dados com os publicados do relatório 2003/5 de autoria do Observatório Europeu de estudos sobre pequenas e médias empresas europeias, analisando as formas de associativismo aqui ocorridas, além de identificar o perfil das empresas e empresários envolvidos no projeto. Para tal análise foram coletados dados de um total de 63 empresas do Projeto Empreender, nos núcleos de Santo André, São Caetano do Sul e Ribeirão Pires. Do GABC foram coletados dados utilizando o instrumento desenvolvido pelo Observatório Europeu de estudos sobre pequenas e médias empresas. A análise dos dados coletados no GABC em relação aos dados europeus se fez necessária para que pudessem ser encontrados pontos de divergências e convergências em cada uma das experiências, objetivando o aprendizado e evolução do tema. A escolha do GABC foi motivada pelo fato da região passar por mudanças no seu perfil econômico, passando de berço e grande pólo das grandes indústrias para um grande centro de pequenas empresas prestadoras de serviços. Após coleta e análise dos dados, percebeu-se que a experiência do GABC e a ocorrida na Itália se parecem em muitos aspectos, porém tem grandes diferenças estruturais. Enquanto o projeto europeu é de responsabilidade de um órgão da União Europeia, aqui o projeto é de autoria do SEBRAE e sofre grandes conflitos com as Associações Comerciais e Industriais (ACIs) da região quando o tema é custeio das despesas das pessoas e estrutura que envolve a implantação do projeto. Além disso, conclui-se que é necessária uma maior aproximação dos municípios com o projeto, tendo em vista que isto poderia ser fator de incentivo a entrada de novas empresas além de fator de aumento de seriedade do sistema. Mais dois dados merecem destaque. Primeiro o fato do Projeto Empreender ter pouca visibilidade regional, ou seja, ser muito pouco divulgado, e o fato da agência de desenvolvimento do GABC não ter aproximação alguma com o projeto. Por último, surgem dados no decorrer da pesquisa que rompem a barreira das teorias administrativas conhecidas, tais como a amizade como fator de associativismo. Portanto, os resultados obtidos com essa pesquisa apontam para a influência no incentivo ao desenvolvimento do processo associativista na região do GABC, além de servir como incentivador para a aproximação de outros atores sociais no processo.(AU)

Industrial networks of the future:review of research and practice

Academic researchers have followed closely the interest of companies in establishing industrial networks by studying aspects such as social interaction and contractual relationships. But what patterns underlie the emergence of industrial networks and what support should research provide for practitioners? Firstly, it appears that manufacturing is becoming a commodity rather than a unique capability, which accounts especially for low-technology approaches in downstream parts of the network, for example in assembly operations. Secondly, the increased tendency towards specialization has forced other, upstream, parts of industrial networks to introduce advanced manufacturing technologies to supply niche markets. Thirdly, the capital market for investments in capacity, and the trade in manufacturing as a commodity, dominates resource allocation to a larger extent than previously was the case. Fourthly, there is a continuous move towards more loosely connected entities that comprise manufacturing networks. More traditional concepts, such as the “keiretsu” and “chaibol” networks of some Asian economies, do not sufficiently support the demands now being placed on networks. Research should address these four fundamental challenges to prepare for the industrial networks of 2020 and beyond.

Inscribing the organization:representations in dispute between accounting and production

This paper assumes that a primary function of management accounting is the representation of "accounting facts" for purposes such as organizational control. Accountants are able to offer conventional techniques of control, such as standard costing, as a consequence of their ability to deploy accounting representations within managerial and economic models of organizational processes. Accounting competes, at times, with other 'professional' groups, such as production planning or quality management people, in this role of representing the organization to management. The paper develops its arguments around a case illustration of cost accounting set in a low technology manufacturing environment. The research relates to a case organization in which accountants are attempting to establish the reliability of accounting inscriptions of a simple manufacturing process. The case research focuses on the documents, the inscriptions that vie for managements' attention. It is these sometimes messy and inaccurate representations which enable control of complex and heterogeneous activities at a distance. At the end of our site visits we observe quality management systems in the ascendancy over the accountants' standard costing systems. © 2006 Elsevier Ltd. All rights reserved.

Valuing transferred machine tool technology:Relating value to product attributes and preferences of acquirers

The value of technology and the appropriate form of transfer arrangement are important questions to be resolved when transferring technology between Western manufacturing firms and partners in industrialising and developing countries. This article reports on surveys carried out in the machine tool industries in the UK and China to establish the differences and similarities between owners and acquirers of technology regarding the relative importance of the factors they evaluate, and the assessments they make, when considering a technology transfer. It also outlines the development of a framework for technology valuation. The survey results indicate that the value of product technology is related to superior technical performance, especially on reliability and functionality, and the prospects of premium prices and increased sales of the technology transfer based machine tools. Access to markets is the main objective of UK companies, while Chinese companies are concerned about improving their technological capability. There are significant risks, especially related to performance in the market, and while owners and acquirers have benefited in the short term, the long term collaboration required for strategic benefits has been difficult to achieve because of the different priorities of the owners and the acquirers.
