This paper addresses reputation and familiarity as determinants of trust in online banking and examines the effects of experience as a moderator in a Latin American context. The study uses data from two countries, Chile and Bolivia that represent the highest and lowest Internet penetration in the region. The effects of reputation and familiarity on trust are supported. However, these relationsh...

Clinical trials and practice have shown that ethambutol is an important component of the first-line tuberculosis (TB) regime. This contrasts the drug's rather modest potency and lack of activity against nongrowing persister mycobacteria. The standard plasma-based pharmacokinetic-pharmacodynamic profile of ethambutol suggests that the drug may be of limited clinical value. Here, we hypothesized ...

[1] This work presents an estimate of anthropogenic CO2 in the Pacific Ocean based on measurements from the WOCE/JGOFS/OACES global CO2 survey. These estimates used a modified version of the DC* technique. Modifications include a revised preformed alkalinity term, a correction for denitrification, and an evaluation of the disequilibrium terms using an optimum multiparameter analysis. The total ...

In this experimental work, Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) were used as activating flux to investigate the effects for SS 304 in tungsten inert gas (TIG) welding. Ultimate tensile strength, percentage elongation, Penetration depth and width were studied of material SS 304. The experimental results indicated that the MnO2 and Fe2O3 flux...

   Nowadays, in addition to materials and components of asphalt mixtures that are bitumen, aggregates and mineral fillers, other materials known as additives or modifiers are also used. These compounds include wide range of organic, inorganic, industrial, and natural materials used in order to reduce deficiencies, to improve the physical properties and to modify some mechanical properties o...

Access control has traditionally assumed a single, monolithic authorization policy, generally expressed as an access matrix. We argue that this assumption does not fit ecommerce applications, which are governed by a potentially large set of independently stated, evolving contracts. In order to support this growing class of applications we propose an enforcement mechanism which uses certified-co...
