13. Análise microbiológica comparativa da ação de diferentes agentes descontaminantes sobre superfícies de titânio / Microbiological comparison of different decontaminant agents on rough and smooth titanium surfaces: microbiological analysis
Actually, the titanium implants are a successful option of treatment in Dentistry. However, failures are possible to occur due to surface exposition to oral environment immediately or lately after its implantation. The titanium implants surfaces can be infected by bacteria and its products similarly to dental roots surfaces. The contaminants turn the inflamm

16. Ocorrência de leite ácido e de resíduos de antimicrobianos no leite cru entregue em laticínios na região do Vale do Taquari, RS, Brasil = Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil / Occurrence of acidity and antimicrobial residues in raw milk delivered at a dairy plant in Vale do Taquari, RS, Brazil
Background: Milk is considered one of the most important sources of nutrients. It contains proteins, fat acids, vitamins and minerals. Its activity has a significant socio-economic impact in all over the world and in Brazil. The presence of bacterial inhibitors in milk for human consumption is a great concern for the dairy products industry and public health

17. Composição do leite e diagnóstico de mastite em caprinos) = Milk composition and mastitis diagnosis in goats / Milk composition and mastitis diagnosis in goats
Background: Milk is one of the most used foodstuffs by humans in their diet. The quality of goat milk is already regulated by Law, which takes into consideration its physical-chemical and microbiological composition parameters. Several factors contribute for the alteration of the physical-chemical and microbiological parameters of caprine milk. These include

19. Use of QFD (Quality Function Deployment) in order to improve milk quality / Uso do metodo DFQ (Desdobramento da Função Qualidade) para melhoria da qualidade do leite fluido
Brazil produces about 130 liters per capita per year, below the rate recommended by the United Nations of 215 liters per capita per year. In the United States, the main reason for the rejection of milk by the consumer is associated with the presence of off flavors. Therefore, the Department of Agriculture of this country was responsible for developing a lang

20. Estudo do efeito da antibioticoterapia profilÃtica prÃ-operatÃria com amoxicilina em cirurgias de terceiros molares. / Study of the effect of preoperative prophylactic antibiotic therapy using Amoxicillin in third molars surgery
Post-operative inflammatory-infectious changes after the removal of third molars are often associated with bacterial contamination of the surgical site in the trans-operative period. Thus, this study aims to conduct a prospective, double-blind, placebo-controlled randomized clinical trial with split-mouth metodology, to evaluate the effect of preoperative pr

21. Antagonismo entre leveduras e bactérias láticas na fermentação alcoólica / Antagonism between yeasts and lactic acid bacteria in alcoholic fermentation
This study aimed to evaluate the antagonism between yeasts and contaminating bacteria of the ethanol production process with different metabolisms (homo- and heterofermentative) in different conditions. Thus, the fermentation performance of Saccharomyces cerevisiae strains used in industrial fermentation (BG-1, CAT-1, PE-2 and Fleischmann) was analyzed in co
