13. Ozone against Pseudomonas aeruginosa biofilms in contact lenses storage cases
ABSTRACT Pseudomonas aeruginosa is associated with ocular infections such as keratitis. Multipurpose contact lens solutions can be used for washing, disinfection and storage of contact lenses, however, P. aeruginosa biofilm disinfection by this method is unsatisfactory. The present study aimed to investigate the effectiveness of ozonated water in reducing P.

14. Comparative study between natural and synthetic Hydroxyapatite: structural, morphological and bioactivity properties
ABSTRACT In this work, a study of hydroxyapatite (HAp) powders obtained using both, porcine bones and chemical precursors was carried put. In the case of HAp obtained by means of porcine bones, physical processes as cooking, washing and milling were developed, for removing the organic material from the bones; after that, the powders were submitted to a therm

15. Tratamiento de efluentes acuosos provenientes de la industria de biodiesel, utilizando tecnología de membranas
ABSTRACT The wastewaters from biodiesel production are generated mainly in the washing process, in this step the contaminants of biodiesel are eliminated in order to the obtained biodiesel meets with the internationals regulations. These wastes contain impurities such as methyl ester, residual oil, mono and diglycerides, soluble salts, catalyst, soap, glycer

16. Feasibility of DLLME for the Extraction and Preconcentration of As and Cd in Sugar for Further Determination by ICP-MS
A method for determining low levels of As and Cd by dispersive liquid-liquid microextraction (DLLME) and inductively coupled plasma mass spectrometry (ICP-MS) was proposed. The following parameters that affect extraction efficiency were investigated: type and volume of extraction solvent (1000 µL acetone), type and volume of dispersive solvent (75 µL carbo

17. BRILLIANT BLUE DYE REMOVAL IN FUNGICIDE SPRAYING
ABSTRACT The method used for removal of brilliant blue dye may have an influence in interpreting the results of spraying deposition studies. The aim of this study was to assess the number of washings and water volumes for brilliant blue dye removal from soybean leaflets and glass slides in fungicide sprayings with and without adjuvants. A completely randomiz

18. Development of Molecularly Imprinted Polymers for Solid Phase Extraction of Parabens in Plasma Samples and Analysis by UHPLC-MS/MS
Two molecularly imprinted polymers (MIPs) were synthesized, by sol-gel and radical polymerization procedures. These MIPs were evaluated as selective stationary phases for miniaturized solid phase extraction (MISPE) to determine parabens in plasma samples by ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Selective cavitie

19. Washing treatment impact on print quality of screen printed knitted fabrics
ABSTRACT The surface of textile materials is highly textured, commonly in non-uniform ways. Because of this texture effect, textile surface appears rougher and more porous than other printing substrates, which can cause excessive ink penetration during printing process. Next, washing process is very important factor because it influences ink characteristics

20. Electrolytic treatment and biosurfactants applied to the conservation of Eugenia uniflora fruit
Abstract Microorganisms are the primary responsible for food poisoning and food spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water and rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order to inhibit microbial growth. The tested organism was Eugenia uniflora. The fruits were

21. Detection of Salmonella spp. by Conventional Bacteriology and by Quantitative Polymerase-Chain Reaction in Commercial Egg Structures
Abstract Conventional bacteriology techniques and quantitative polymerase-chain reaction (qPCR) were applied to the eggshell, albumen, and yolk of washed and unwashed commercial white and brown eggs, to detect Salmonella spp. Pooled samples of eggshells, albumen, and yolk of white and brown eggs were collected at the poultry house and at the egg-storage room

22. Effects of Types of Washing and Peeling in Relation to Pesticide Residues in Tomatoes
Tomatoes are widely consumed and most often without cooking, therefore it is important to estimate the reduction of residues using simple washing procedures. An experiment was carried out to evaluate the effects of household processing such as: washing with water, washing with 10% of vinegar solution and washing with 10% of sodium bicarbonate solution on pes

23. MODELLING OF DISPLACEMENT WASHING OF PULP FIBERS USING THE HERMITE COLLOCATION METHOD
AbstractA non-linear mathematical model for displacement washing of pulp fibers with suitable boundary conditions is presented. Model equations are divided into two phases: particle phase and external fluid phase. The Hermite collocation method (HCM) is employed to solve the non-linear model equations. The validity and efficiency of the proposed model is dem

24. Effectiveness of sperm washing by discontinuous density gradient centrifugation to remove antibodies bound to the sperm membrane
OBJECTIVE: We evaluated the effectiveness of sperm washing using the discontinuous two-layer density gradient centrifugation method to remove antisperm antibodies attached to the sperm surface. METHOD: We prospectively enrolled sixty-six men with unexplained infertility who were seeking evaluation. Each patient delivered one semen specimen for the study. W
