O presente artigo primeiramente trata do processo de globalização da indústria automobilística internacional. da mesma forma, o importante papel desempenhado pela introdução de novas tecnologias nessa indústria é também considerado. As mudanças recentes e principais tendências das estratégias competitivas - em particular no tocante à globalização e aos produtos - implementadas por algumas das principais montadoras da indústria automobilística mundial (GM, Ford, Toyota, VW, Fiat) são também examinadas. Por fim, são considerados os planos internacionais e o mercado interno brasileiro.

The present work aimed at studying the effect of five doses of zinc (0, 1.0, 2.0, 3.0 and 4.0 ppm) in three levels of soil correction. A Dark-Red Latosol, clay texture, oryginally recovered by cerrado vegetation was used. Soybean was used as test plant, cultivated in green-house conditions. The zinc dose affected dry matter production of aerial parts and grain only in the treatments that received the corrective. The concentration of the element in the soil increased linearly with the dose application, and the critical levels in soil (90% of the maximal yield) were between 0.27 and 0.37 ppm of zinc in the treatments with the equivalent to 2.0 t/ha and 3.2 t/ha of lime, respectively.

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.
