Abstract: In this study corrosion rates of aluminum, copper, brass and Stainless Steel 304 (SS 304) in tequila are reported from potentiodynamic polarization and Electrochemical Impedance Spectroscopy (EIS) measurements. A simple kinetic model is proposed to analyze the polarization data and to establish a comparison with EIS measurements. For the examined metals/alloys, aluminum exhibited the highest corrosion rate of ca. 6.1 pm s-1 with a pitting corrosion tendency after being exposed to tequila (pH = 3.6). SS 304 was the most stable metal with a corrosion rate of 0.28 pm s-1. The corrosion rate trends for all the investigated metals/alloys from potentiodynamic polarization and EIS measurements are Al > Cu > brass> SS 304.

Partial phase diagrams at 60 °C show that the addition of n-butanol enhances the one-phase microemulsion region. Results indicate that the reaction rate is not affected by the presence of the alcohol. However, average molar masses are smaller although particles are bigger throughout the reaction compared to those values obtained in the absence of n-butanol.

DESIGN: Cross-sectional. SETTING: Fourteen nursing homes in Guadalajara. PARTICIPANTS: Data were drawn from a random sample of 451 elderly, aged 60-104 years. MEASUREMENTS: The Spanish versions of MMSE (Folstein). ADL index (Barthel), and the Geriatric Depression Screening (GDS) (Yesavage); demographic factors were obtained. RESULTS: The prevalence of cognitive impairment was 52.3%, with a cut-off of 19/20 (Bohnstedt). Cognitive impairment was significantly related to gender, educational level, activity participation, pension, ADL, and depression. CONCLUSION: The results indicate a higher prevalence of cognitive impairment than in other Mexican studies. The data are consistent with previous findings that cognitive impairment in the elderly is more common among females, those with a low level of education, the lack of participation in social/leisure activities, ADL dependencies, and depression.",,,,,,,,,"http://hdl.handle.net/20.500.12104/40384","http://www.scopus.com/inward/record.url?eid=2-s2.0-0037272818&partnerID=40&md5=1de49834fd6791ab26ada6a470f94da8",,,,,,"2",,"Journal of Nutrition, Health and Aging",,"97

Gomez-Salazar, S.",,"2011",,"An ion-exchange resin was employed to remove copper from tequila. Elemental analysis, batch and column copper uptake measurements were performed to assess the extent of metal removal; FTIR and XPS were employed to elucidate the copper complexes formed on the surface of resin; GC was used to investigate resin fouling and the extent of methanol removal. A modified Langmuir isotherm was used to explain adsorption equilibrium data. A ligand density of 2.21 mmol/g as sulphonic group, was measured. Maximum copper uptake by resin was 0.59 mmol/g. GC results from column experiments revealed methanol changes from 311 mg/100 ml anhydrous alcohol (AA) to 212 mg/100 ml AA, complying with Mexican regulations. Tequila solution with copper (5.3 l, 7.3 mg/l) was treated to breakthrough point in column experiments reaching 0.5 mg/l of copper at effluent. These results comply with the Mexican regulation for copper concentration (?2 mg/l) showing the promise of resin for industrial applications in removal of copper and methanol from tequila.
