13. Evaluation of antifungal activity in essential oil of the Syzygium aromaticum (L.) by extraction, purification and analysis of its main component eugenol
Antifungal properties of some essential oils have been well documented. Clove oil is reported to have strong antifungal activity against many fungal species. In this study we have evaluated antifungal potential of essential oil of Syzygium aromaticum (L.) against some common fungal pathogens of plants and animals namely, Fusarium moniliforme NCIM 1100, Fusar

14. Efficacy of clove oil as anesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Actinopterygii: Cichlidae) juveniles
This work evaluated the efficiency of clove oil as anaesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). In the first experiment, safety concentrations of clove oil were assessed by measuring induction times to anaesthesia. The second experiment evaluated exposure times to anaesthetic. Clove oil efficiency during

15. Antimicrobial activity of essential oils against Vancomycin-Resistant enterococci (VRE) and Escherichia coli O157:H7 in feta soft cheese and minced beef meat
Eleven essential oils (EOs) were evaluated for their antibacterial properties, against Vancomycin-Resistant Enterococci (VRE) and E. coli O157:H7. EOs were introduced into Brain Heart Infusion agar (BHI) (15ml) at a concentration of 0.25 to 2% (vol/vol) to determine the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for e

16. The effective duffusivity of clove (Eugenia caryophyllus) essential oil in pressurized CO2 / Estimativa da difusividade mássica efetiva do óleo essencial de cravo-da-índia (Eugenia caryophyllus) em CO2 pressurizado
O coeficiente de difusão efetivo do óleo essencial de cravo-da-índia em CO2 líquido subcrítico foi estimado. O equipamento experimental usado foi um extrator de leito fixo. O leito fixo foi formado por cravo-da-índia moído (mesh -32 + 65) e compactado, sendo assim considerado como um meio sólido. O coeficiente de difusão efetivo foi estimado pelo aj

17. Cardanol e Eugenol Modificados Uso Como Antioxidante no Controle do Processo Oxidativo do Biodiesel de Algodão / Modified Cardanol and Eugenol Using as Antioxidant on the control of the Oxidative Process in Cotton Biodiesel
Biodiesel is composed by a mixture of different kinds of esters that may have unsaturations in their chains. These unsaturations are susceptible to oxidation processes, especially in the presence of oxygen. The oxidative stability of biodiesel becomes therefore an important quality parameter since the oxidation of the esters may cause some problems when usin

18. Relaxamento do músculo liso traqueal de rato pelo eugenol. / Relaxation of rat tracheal smooth muscle by eugenol.
Eugenol, a phenol monoterpenoid, is the main component of clove oil. This study aims to evaluate the relaxation of tracheal smooth muscle of rat by eugenol and the mechanisms underlying these effects. We used preparations of trachea of male Wistar rats maintained in aerated modified Tyrode to record isometric muscle contractions. Increasing and cumulative co

20. Plant extracts used as growth promoters in broilers
Two experiments were carried out to assess the efficacy of plant extracts as alternatives for antimicrobial growth promoters in broiler diets. The performance experiment included 1,200 male broilers raised from 1 to 42 days of age. The metabolism experiment used 96 male broilers in the grower phase housed in metabolic cages for total excreta collection. At t

22. Potencial de Ãleos essenciais no manejo da ferrugem e da cercosporiose do cafeeiro / Potential of the essential oils in the control of leaf rust and brown spot eye of coffee plant
The rust and brown spot eye are considered the main diseases of coffee plant, it reduces the production and undermine the drink quality. The management of the disease is conventionally done by application of copper and systemic fungicides, however, they may promote the contamination of man, environment and select resistant pathogens races. Thus, the essentia

23. Application of interval analysis for gibbs and helmholtz free energy global minimization in phase stability analysis
The tangent plane criterion has become important for a correct solution evaluation phase and chemical of equilibrium problem. This method, applicable to single and multiphase systems, is mainly used for a single equation of state modeling all phases involved. The present work is mainly concerned with the application of interval analysis methods for global en

24. Extratos vegetais como alternativas aos antimicrobianos promotores do crescimento de leitões recém-desmamados / Herbal extracts as alternatives to antimicrobial growth promoters of weanling pigs
The use of antimicrobial as growth promoters in the animal feed has been related to an increase on animal performance. However, due to the restriction of many countries to the use of antimicrobial as growth promoters, alternatives are being studied. So, the purpose of this work was to evaluate herbal extracts as alternatives to antimicrobial growth promoters
