Adaptação da produção aos objetivos de competitividade e produtividade: a pesquisa-ação em uma manufatureira de cutelaria inserida em rede

One of the oldest segments in operations management, whose models are always subject to development efforts, for academics and productive organizations, is the management of production and work organization. Proposals for strategic management principles that seek to bring production to streamline processes reduce costs and add value, identifying problems with material flow and information while reducing the response time. This is realized through the pursuit of the best actions to achieve goals and targets established in a successful Planning and Production Control. This article aims to identify and implement actions that increase the speed of supply of goods produced in a enterprise cutlery; positively influencing the perception of customers. Such attitudes benefit all actors involved in the network, a fact which is expressed in the production chain. To lay the foundations of research and validate the data obtained, it was a study drawing on action research methodology. The goods produced are sold, mainly to wholesalers. Was proved seven aspects to improve and enhance the competitiveness of the organization, among them the complete design of the network, integrating upstream and downstream actors.

Avaliação da eficácia dos biocurativos em ratos wistar com lesões de pele causadas por queimaduras

Accidents caused by thermal, chemical, electrical or radioactive agents cause skin lesions causing burns of varying degrees. The therapeutic approach aims to restore damaged tissues and involves a wide range of products on the market. This study aims to evaluate the use of biological dressing, biotech product developed at the Blood Center of Botucatu / UNESP obtained from fresh frozen plasma or platelet concentrate with in vitro addition of thrombin and calcium gluconate. This addition in the platelet concentrate, intended to release the active growth factors of the platelets granules on the healing process. The study of the effectiveness of Platelet Gel home made in Wistar rats was established, in agreement with scald burns, comparing efficacy and cost of Platelet Gel with usual hospital -based treatment collagenase + chloramphenicol plus cost analysis through pharmacoeconomics. We used 25 Wistar rats were divided into 3 treatment groups: Group A, Collagenase + Chloramphenicol; Group B, Platelet Gel and C, control. The products were applied every other day for 30 days in animals. In group A, there was the presence of erythema and crust in all animals. The exudates was indentified 2/10 animals. For the Group B, we observed the presence of erythema and crust at all and no presence of exudates. In group C all the animals showed erythema with no presence of exudates and scab occurred in 1/10. Statistical analysis showed significant difference ( p < 0.0 ) for crust formation between Groups B and C. In the histological analysis, group A showed a slight amount of blood vessels and collagen fibers, moderate amounts of macrophages and fibroblasts was observed while B and C groups showed moderate amounts of blood vessels, macrophages and fibroblasts and discreet presence of collagen fibers. The re-epithelialization occurred in most animals of all groups without significant statistical differences. For the aspects of pharmacoeconomics, the platelet gel presented a better cost - effectiveness in relation to treatment based on collagenase / chloramphenicol. In light of the ethical aspects of the raw material is the result of spontaneous blood donation, the proposal should have biological dressings productions the responsibility of public blood transfusion centers for free distribution. This may point to the production chain of Brazilian blood banks like special blood components for use no intravenous.

Bamboo as sustainable material used in design and civil construction: species, management, characterization and applications

The use of bamboo as construction and raw material for producing products can be considered a feasible alternative to the abusive use of steel, concrete and oil byproducts. Its use can also reduce the pressure on the use of wood from native and planted forests. Although there are thousands of bamboo species spread about the world and Brazil itself has hundreds of native species, the use and basic knowledge of its characteristics and applications are still little known and little disseminated. This paper's main objective is to introduce the species, the management phases, the physical and mechanical characteristics and the experiences in using bamboo in design and civil construction as per the Bamboo Project implemented at UNESP, Bauru campus since 1994. The results are divided into: a) Field activities - description of the technological species of interest, production chain flows, types of preservative treatments and clump management practices for the development, adaptation and production of different species of culms; b) Lab experiments - physical and mechanical characterization of culms processed as laminated strips and as composite material (glue laminated bamboo – glubam); c) Uses in projects - experiences with natural bamboo and glubam in design, architecture and civil construction projects. In the final remarks, the study aims to demonstrate, through practical and laboratory results, the material's multi-functionality and the feasibility in using bamboo as a sustainable material.

Construção de um indicador qualitativo (status de saúde) para avaliação da qualidade de saúde animal de propriedades rurais

Aiming at developing a tool for assessing the magnitude of farm animal health, an indicator named herd “animal health status” was built. To illustrate the construction of the indicator, serum samples were taken from 923 goats on 17 goat farms in the state of Sao Paulo, Brazil, where three diseases were evaluated along with their impact percentages: caprine arthritis encephalitis, toxoplasmosis and neosporose – all of an infectious and transmissible nature and the cause of considerable economic losses. The mathematical rationale underlying the building of the “animal health status” indicator ranks properties on a 0 - 100% scale in terms of disease positivity in the herd, with the lowest indicator value indicating the highest cumulative disease frequency (0% = all animals tested positive for the three diseases, 100% = all animals tested negative for all diseases). Anti-T. gondii, anti-N. caninum and anti-CAEV antibodies were tested using indirect immunofluorescence reaction (IIFR ≥ 16), Neospora agglutination test (NAT ≥ 25) and agarose gel immunodiffusion (AGID positive or negative), respectively. The animal health status of the farms ranged from 32.38% to 96.40% according to disease positivity. The animal health status value will have a direct reflection on the production chain both on and off the farm, providing not only great market advantages, due to how the expression of animal health will add value to livestock farms, as well as on the consumer who can check the quality of animal health at the beginning of the production chain.

Inovação tecnológica de boas práticas agrícolas e a informática na gestão agropecuária

This study aims to develop innovative proposals for production agriculture management and plans to build a participatory model, through the digital inclusion of members of the family farm gathered in a cooperative venture seeking to establish new environmental management efficiency for household production. The first part of the hypothesis assumes that a major obstacle to the insertion of small family farms into the markets is skilled labor, human capital. A training model has been developed for traceability and tracking activities on family farms, based on the atemoya culture. The second hypothesis predicts that it is possible to create a model that is scientifically supported by widely accepted rules derived from GlobalGAP standard certification, a global benchmark for good agricultural practices. Using these rules the model seeks to achieve the traceability of agricultural products and operations from the preservation of identity information within the production chain. The results obtained by the computerized system confirmed the presented hypotheses by demonstrating that technological innovation through intensive communication and information technologies education as well as other associated forms are important drivers of regional development, especially if implemented through a digital inclusion project using the state program Infocentros Access São Paulo.

Genotoxicity assessment of water soluble fractions of biodiesel and its diesel blends using the Salmonella assay and the in vitro MicroFlow (R) kit (Litron) assay

The designation of biodiesel as an environmental-friendly alternative to diesel oil has improved its commercialization and use. However, most biodiesel environmental safety studies refer to air pollution and so far there have been very few literature data about its impacts upon other biotic systems, e.g. water, and exposed organisms. Spill simulations in water were carried out with neat diesel and biodiesel and their blends aiming at assessing their genotoxic potentials should there be contaminations of water systems. The water soluble fractions (WSF) from the spill simulations were submitted to solid phase extraction with C-18 cartridge and the extracts obtained were evaluated carrying out genotoxic and mutagenic bioassays [the Salmonella assay and the in vitro MicroFlow (R) kit (Litron) assay]. Mutagenic and genotoxic effects were observed, respectively, in the Salmonella/microsome preincubation assay and the in vitro MN test carried out with the biodiesel WSF. This interesting result may be related to the presence of pollutants in biodiesel derived from the raw material source used in its production chain. The data showed that care while using biodiesel should be taken to avoid harmful effects on living organisms in cases of water pollution. (C) 2011 Elsevier Ltd. All rights reserved.

Un piano territoriale per la riduzione della concentrazione di CO2 nell'atmosfera e la produzione energetica da fonti rinnovabili per mezzo della filiera delle biomasse

Il progetto propone uno studio per verificare la fattibilita' di un piano territoriale (ideato per il bacino del Po ma di fatto estendibile a tutti i bacini fluviali) per la creazione di una filiera di colture bioenergetiche (biomasse) che, trasportate per mezzo della navigazione fluviale (uno dei mezzi di trasporto a minore emissione di CO2), alimentino una o piu' centrali a nuova tecnologia che associno alla produzione di calore (teleriscaldamento e raffreddamento) e di energia la separazione dei fumi. La CO2 catturata dalla crescita delle biomasse e recuperata dalla combustione, puo' quindi essere segregata nel sottosuolo di aree costiere subsidenti contrastando il fenomeno dell’abbassamento del suolo. Ricavando benefici in tutti i passaggi di attuazione del piano territoriale (lancio dell'agricoltura bioenergetica, rilancio della navigazione a corrente libera, avvio di una economia legata alla logistica del trasporto e dello stoccaggio delle biomasse, generazione di energia pulita, lotta alla subsidenza) il progetto, di fatto, consente di catturare ingenti quantitativi di CO2 dall'atmosfera e di segregarli nel sottosuolo, riducendo l'effetto serra. Nel corso del Dottorato e' stata sviluppata una metodologia di valutazione della sostenibilita' economica ed ambientale del progetto ad un bacino fluviale, che consta di una modulistica di raccolta dei dati di base e di una procedura informatizzata di analisi.

Le aziende vitivinicole: da “machines à produire” a elementi di attrazione nel paesaggio. Proposte e criteri progettuali per l’efficienza funzionale e la qualità architettonica ed ambientale delle strutture ed infrastrutture della trasformazione enologica.

La ricerca ha per oggetto la messa a punto e applicazione di un approccio metaprogettuale finalizzato alla definizione di criteri di qualità architettonica e paesaggistica nella progettazione di aziende vitivinicole medio-piccole, che effettuano la trasformazione della materia prima, prevalentemente di propria produzione. L’analisi della filiera vitivinicola, della letteratura scientifica, della normativa di settore, di esempi di “architetture del vino eccellenti” hanno esplicitato come prevalentemente vengano indagate cantine industriali ed aspetti connessi con l'innovazione tecnologica delle attrezzature. Soluzioni costruttive e tecnologiche finalizzate alla qualità architettonica ed ambientale, attuali dinamiche riguardanti il turismo enogastronomico, nuove funzionalità aziendali, problematiche legate alla sostenibilità dell’intervento risultano ancora poco esplorate, specialmente con riferimento a piccole e medie aziende vitivinicole. Assunto a riferimento il territorio ed il sistema costruito del Nuovo Circondario Imolese (areale rappresentativo per vocazione ed espressione produttiva del comparto vitivinicolo emiliano-romagnolo) è stato identificato un campione di aziende con produzioni annue non superiori ai 5000 hl. Le analisi svolte sul campione hanno permesso di determinare: modalità di aggregazione funzionale degli spazi costruiti, relazioni esistenti con il paesaggio, aspetti distributivi e materico-costruttivi, dimensioni di massima dei locali funzionali alla produzione. Il caso studio relativo alla riqualificazione di un’azienda rappresentativa del comparto è stato utilizzato per la messa a punto e sperimentazione di criteri di progettazione guidati da valutazioni relative alle prestazioni energetiche, alla qualità architettonica e alla sostenibilità ambientale, economica e paesaggistica. L'analisi costi-benefici (pur non considerando le ricadute positive in termini di benessere degli occupanti ed il guadagno della collettività in termini di danni collegati all’inquinamento che vengono evitati in architetture progettate per garantire qualità ambientale interna ed efficienza energetica) ha esplicitato il ritorno in pochi anni dell’investimento proposto, nonostante gli ancora elevati costi di materiali di qualità e dei componenti per il corretto controllo climatico delle costruzioni.

LCA-GIS Integrated approach for a Sustainable Land Use Under Energy Crops

In genere, negli studi di vocazionalità delle colture, vengono presi in considerazione solo variabili ambientali pedo-climatiche. La coltivazione di una coltura comporta anche un impatto ambientale derivante dalle pratiche agronomiche ed il territorio può essere più o meno sensibile a questi impatti in base alla sua vulnerabilità. In questo studio si vuole sviluppare una metodologia per relazionare spazialmente l’impatto delle colture con le caratteristiche sito specifiche del territorio in modo da considerare anche questo aspetto nell’allocazione negli studi di vocazionalità. LCA è stato utilizzato per quantificare diversi impatti di alcune colture erbacee alimentari e da energia, relazionati a mappe di vulnerabilità costruite con l’utilizzo di GIS, attraverso il calcolo di coefficienti di rischio di allocazione per ogni combinazione coltura-area vulnerabile. Le colture energetiche sono state considerate come un uso alternativo del suolo per diminuire l’impatto ambientale. Il caso studio ha mostrato che l’allocazione delle colture può essere diversa in base al tipo e al numero di impatti considerati. Il risultato sono delle mappe in cui sono riportate le distribuzioni ottimali delle colture al fine di minimizzare gli impatti, rispetto a mais e grano, due colture alimentari importanti nell’area di studio. Le colture con l’impatto più alto dovrebbero essere coltivate nelle aree a vulnerabilità bassa, e viceversa. Se il rischio ambientale è la priorità, mais, colza, grano, girasole, e sorgo da fibra dovrebbero essere coltivate solo nelle aree a vulnerabilità bassa o moderata, mentre, le colture energetiche erbacee perenni, come il panico, potrebbero essere coltivate anche nelle aree a vulnerabilità alta, rappresentando cosi una opportunità per aumentare la sostenibilità di uso del suolo rurale. Lo strumento LCA-GIS inoltre, integrato con mappe di uso attuale del suolo, può aiutare a valutarne il suo grado di sostenibilità ambientale.

Glycerol oxidehydration to acrylic acid on complex mixed-metal oxides

The project of this Ph.D. thesis is based on a co-supervised collaboration between Università di Bologna, ALMA MATER STUDIORUM (Italy) and Instituto de Tecnología Química, Universitat Politècnica de València ITQ-UPV (Spain). This Ph.D. thesis is about the synthesis, characterization and catalytic testing of complex mixed-oxide catalysts mainly related to the family of Hexagonal Tungsten Bronzes (HTBs). These materials have been little explored as catalysts, although they have a great potential as multifunctional materials. Their peculiar acid properties can be coupled to other functionalities (e.g. redox sites) by isomorphous substitution of tungsten atoms with other transition metals such as vanadium, niobium and molybdenum. In this PhD thesis, it was demonstrated how it is possible to prepare substituted-HTBs by hydrothermal synthesis; these mixed-oxide were fully characterize by a number of physicochemical techniques such as XPS, HR-TEM, XAS etc. They were also used as catalysts for the one-pot glycerol oxidehydration to acrylic acid; this reaction might represent a viable chemical route to solve the important issue related to the co-production of glycerin along the biodiesel production chain. Acrylic acid yields as high as 51% were obtained and important structure-reactivity correlations were proved to govern the catalytic performance; only fine tuning of acid and redox properties as well as the in-framework presence of vanadium are fundamental to achieve noteworthy yields into the acid monomer. The overall results reported herein might represent an important contribution for future applications of HTBs in catalysis as well as a general guideline for a multifaceted approach for their physicochemical characterization.
