The main goal of this work is to present a supplier's management method based on evaluation of audits performed at suppliers during products development phase. Audits are prioritized according to the impact of supplied parts on the development and its main goals are identification of risks, to propose and perform action plans and to evaluate periodically the supplier's performance to prevent problems. It is proposed that if the audits in the development phase be efficient, the supplied products will have good maturity to entry into service and stable performance. This issue was evaluated in a aeronautic company and the analyzed results in 2006 were considered good.

Avaliação comparativa da eficácia de fitoterápicos e produtos químicos carrapaticidas no controle do boophilus microplus (Canestrini, 1887) por meio do biocarrapaticidograma

The aim of this research was to evaluate the efficacy of plant extracts and chemical products for the control of Boophilus microplus. Three commercial products for the control of Boophilus microplus were in vitro evaluated, chemical compounds of cypermethrin + DDVP and organophosphate as recomended by the manufacturer, and also four plant extracts, Azadirachta indica (1%), Cymbopogon densiflorus, Lippia alba and Ipomoea asarifolia at different concentrations. The results showed that the chemical compounds tested had efficacy lower than 95% against the Boophilus microplus samples in the experiment. The extracts of all plants have shown some biological activity in the mortality of ingurgitated females and inhibition of egg crash, however the extract of Azadirachta indica presented efficacy higher than 95% in all tested concentrations, being the best sample tested in this experiment.

Efecto de la fertirrigación con n y k en el crecimiento de la palma de coco enano Verde de jiqui

The coconut palm crop has increased with the use of the fertigation technique in Brazil in the last years. The objective of this work was to evaluate the influence of N and K rates via fertigation, on vegetative growth of three year old palms, cultivated in the littoral region of the Ceará State, Brazil, with tropical rainy climate. The study was conducted in a sandy soil using the variety of green dwarfed Jiqui coconut palm. The experimental design was a randomized complete block, with 10 treatments, including five nitrogen and five of potassium rates, according to the model of the experimental matrix Plan Puebla III. The nitrogen and potassiun applications via fertigation influenced significantly the plant height, stem perimeter, and the number of leaves and folioles. © 2009 Universidad Centroccidental Lisandro Alvarado (UCLA).

Ensaios biológicos para avaliação de segurança de produtos cosméticos

Despite efforts to the contrary, some cosmetic products can cause undesirable side effects in the users. These may often be due to individual factors or inappropriate use of the product. Thus, biological assays to assess the safety of a new cosmetic must precede its being placed on the market. Historically, these tests have always been carried out in vivo, in animals, since such tests can be used to evaluate many of the potential risks, such as irritation, allergy or systemic effects; but, recently, some research centers have been adopting in vitro alternatives, in order to replace the animal tests. This review emphasizes the need to employ biological assays to test the safety of cosmetic products, and reviews the main in vivo and in vitro tests used, focusing on the need to develop and use alternatives to the in vivo assays of product safety, so as to offer the consumers the maximum safety with the least possible risk, while ensuring the best conditions of use of the product.

Fatores antinutricionais e coeficientes de digestibilidade aparente da proteína de produtos de soja para o pacu (Piaractus mesopotamicus)

This study aimed to determine the activities of trypsin inhibitors, hemagglutinant and tannin levels in soybean meal and in raw and processed soy, as well evaluate the protein apparent digestibility coefficient for pacu juveniles. The apparent coefficients of raw, extruded, toasted and milled soy were determined using chromium oxide (0.5%) as marker. A reference diet was created with 26% crude protein and 4,352 kcal kg-1, with each feed containing 30% of the test diet. Feces were collected by abdominal pressure. All analyzed products presented anti-nutritional factors, but the lowest trypsin inhibitor activity was observed in soybean meal. Soy that received thermal treatment presented better digestibility coefficients and lower hemagglutinating activity values than raw soy. No effects of trypsin and tannin inhibitor were observed on the protein digestibility coefficient, but a negative relationship was observed between hemagglutinin levels and protein digestibility coefficient. The use of soybean meal and extruded or toasted soy is recommended for pacu feeding.

Produtos naturais no comportamento defensivo de Apis mellifera L.

The goal was to investigate the influence of natural products such as lemongrass (Cymbopogon citratus), dried avocado leaves (Persea americana), coffee husk (Coffea arabica) and castor bean (Ricinus communis) in the defense of Apis mellifera, as well the effect of these products on the population development of the beehive. Defensive behavior was evaluated by time of first sting (TFS) and number of stingers (NS), and population development, by open brood area and operculated brood. It was observed that the treatment with smoke + seven castor beans presented significant increase in the TFS, for treatment without and with smoke. Regarding NS, it was verified that the treatments with smoke + seven castor bean and smoke + 20% coffee husk were different from the treatment without and with smoke. The other treatments did not differ significantly with respect to the use of smoke or its absence. The application of coffee husk and castor bean did not interfere in the development of the population, suggesting that these compounds were not toxic. It can be concluded that the use of castor bean and coffee husk in smoke may represent an important tool for the reduction of defensiveness, without promoting toxicity for A. mellifera.

Caracterização radiométrica de ácidos fosfóricos e seus produtos industriais

The addition of phosphoric acids and their (by)products became a common practice in areas like metal treatment, detergent production, water and effluent treatment, as well by food, beverage and pharmaceutical industries. The phosphoric acids exhibit different radionuclides activity concentration, being important to evaluate the implications for the human and animal health. The 238U concentration in almost all raw acid phosphoric are within the worldwide range and the mean exposure rate for the filtration cake is 10 nGy/h, which is mainly attributed to 40K. The results obtained for total and (bio)available uranium concentration in filtration cake indicate that only 40% is (bio)available for plants. The radionuclides present in phosphoric acid food grade and filtration cake do not raise their concentration in human food chain or soils to harmful levels, consequently, not offering hazard to the ecosystem and animal or human health.

Efeito de produtos químicos sobre a mancha bacteriana (xanthomonas perforans) e na ativação de proteínas relacionadas à patogênese em tomateiro

The present study aims to evaluate the effect of fungicides and antibiotics to control bacterial spot (Xanthomonas perforans) in tomato, and the activation of pathogenesis-related proteins. Hybrid tomato AP 529 was used to assess the severity of disease. The treatments consisted of spraying with acibenzolar-S-methyl, fluazinam, pyraclostrobin, pyraclostrobin + methiran, copper oxychloride, copper oxychloride and mancozeb + oxytetracycline, and inoculated and non-inoculated controls. After three days of treatment, all plants were inoculated with X. perforans (10 6 CFU / mL). Leaf discs were collected for assessment of peroxidase, polyphenol oxidase, β-1,3 glucanase, phenylalanine ammonia lyase and protease. The area under the disease progress curve (AUDPC) was calculated with the data of severity. All treatments had reduced AUDPC compared to the inoculated control. Fungicides acibenzolar-S-methyl, pyraclostrobin, and pyraclostrobin + methiran had more satisfactory results in reducing the severity of bacterial spot on tomato. The products based on pyraclostrobin together with acibenzolar-S-methyl induced enzymatic activities of peroxidase, polyphenoloxidase and β-1,3 glucanase, indicating that these products may be related to the induction of resistance to bacterial spot on tomato plants.

Fungos endofíticos: Uma fonte inexplorada e sustentável de novos e bioativos produtos naturais

Endophytic fungi are a rich source of new and biologically active natural products. They colonize a relatively unexplored ecological habitat and their secondary metabolism is particularly active, presumably due to metabolic interactions with their hosts. In the course of our continuing investigations for new and bioactive compounds from endophytic fungi from brazilian flora Alibertia macrophylla, Caseria sylvestris, Ocotea corymbosa, Cassia spectabilis, Piper aduncum, Cryptocaria mandioccana, Xylopia aromatica and Palicourea marcgravii were investigated. Forty two natural products were isolated and their structures were established on the basis of comprehensive spectral analysis, mainly using 1D and 2D NMR experiments. The compounds were tested in their antifungal, antioxidant, anticholinesterasic and anticancer activities.
