Com o objetivo de aprofundar investigações anteriores, foram realizadas modificações superficiais diretas em eletrodos de diamante dopados com boro (DDB), com óxidos metálicos (PtO x , RuO 2 , IrO 2 e PbO 2 ) e com alguns compósitos mistos, utilizando a técnica Sol-Gel. Estes materiais foram estudados por microscopia de força atômica (MFA) e os resultados indicaram a formação de sítios de depos...

The Person Trade-Off (PTO) is a methodology aimed at measuring the social value of health states. It is claimed that other methods measure individual utility and are less appropriate for taking resource allocation decisions. However, few studies have been conducted to test the apparent superiority of the method for this particular kind of decision. We present a pilot study to this end. The stud...

OBJECTIVE The purpose of this observational study was to describe the associations between cultural beliefs that are prevalent in older African Americans and adherence to diabetes self-management (DSM) behaviors. METHODS In a community population of 110 older African Americans with type 2 diabetes, the investigators administered surveys that assess present time orientation (PTO), future time ...

Proximal tubal occlusion (PTO), until recently a domain of microsurgery, can also be treated by a transcervical balloon dilatation and/or tubal recanalization. The aim of our study was to evaluate the possibility of transcervical tubal dilatation during transcervical Falloposcopy. Transcervical Falloposcopy and tubal dilatation was performed under laparoscopic control. During a period of 48 mon...

We report the results from two surveys designed to explore whether an application of Harsanyi's principle of choice form behind a veil of ignorance (VEI) can be used in order to measure the health of populations. This approach was tentatively recommended by Murray et al. (Bull. World Health Organ 2000; 78: 981-994; Summary Measures of population health: Concepts, Ethics, Measurement and Applica...

A key virulence strategy of bacterial pathogens is the delivery of multiple pathogen effector proteins into host cells during infection. The Hrp outer protein Q (HopQ1) effector from Pseudomonas syringae pv tomato (Pto) strain DC3000 is conserved across multiple bacterial plant pathogens. Here, we investigated the virulence function and host targets of HopQ1 in tomato (Solanum lycopersicum). Tr...

The Japanese eel larvae hatch near the West Mariana Ridge seamount chain and travel through the North Equatorial Current (NEC), the Kuroshio, and the Subtropical Countercurrent (STCC) region during their shoreward migration toward East Asia. The interannual variability of circulation over the subtropical and tropical regions of the western North Pacific Ocean is affected by the Philippines-Taiw...

Many believe the root cause of the patent system's dysfunction is that the U.S. Patent & Trademark Office (PTO or Agency) is issuing too many invalid patents that unnecessarily drain consumer welfare. Concerns regarding the Agency's over-granting tendencies have recently spurred the Supreme Court to take a renewed interest in substantive patent law and have driven Congress to enact the first ma...

The ideal intrinsic barriers to domain switching in c-phase PbTiO3 PTO , PbZrO3 PZO , and PbZr1−xTixO3 PZT are investigated via first-principles computational methods. The effects of epitaxial strain on the atomic structure, ferroelectric response, barrier to coherent domain reversal, domain-wall energy, and barrier to domain-wall translation are studied. It is found that PTO has a larger polar...
