The aim of the present study was to provide a general scheme for pulpectomy of primary molars that may be useful for decision-making about negotiation of root canals and selection of appropriate instruments. A total of 160 vital primary molars in 85 patients (40 males, 45 females) aged 4-6 years were selected. After taking primary radiographs, local anesthesia was induced, and the teeth were is...

Companies employ the World Wide Web (Web) to gather and disseminate information to and from actual and potential customers and increasingly for endconsumer business transactions through Electronic Commerce (EC). Online barriers limit or eliminate Web accessibility for many potential customers with access challenges. It is difficult to establish, develop and manage relationships with potential c...

In a short period of time, the World Wide Web has had a huge impact on our society and lives. In web sites and web applications, accessibility and usability are essential key requirements. Unfortunately, most web sites are inaccessible to many disabled people and fail to satisfy the most basic standards for accessibility. Many of the barriers people with disabilities face on the Web are complet...

Increased vascular calcification and tortuosity are rather common in end-stage renal failure patients who are on hemodialysis. It renders manipulation of catheters and performance of percutaneous transluminal interventions more difficult than expected. Such vascular alterations may be evident in large veins and pose significant difficulties in placement of pacing leads as shown in our case. To ...

User acceptance is a high priority for website design and implementation. Two significant, but largely separate, approaches to acceptability are: First, the Web Accessibility Initiative (WAI) has explored the measurement of technical features of a website to gauge its accessibility. Second, human judgments about acceptability are obtained from intended users or experts. The present work explore...

Flexibility and adaptivity are two of the outstanding characteristics of new media and new technologies. These properties allow new methods to provide physically challenged people with appropriate information. To build accessible Web applications, one has to respect the needs from the beginning of the design process. However, it is difficult to integrate the requirements of accessibility guidel...

Two studies demonstrated that attempts to debias hindsight by thinking about alternative outcomes may backfire and traced this to the influence of subjective accessibility experiences. Participants listed either few (2) or many (10) thoughts about how an event might have turned out otherwise. Listing many counterfactual thoughts was experienced as difficult and consistently increased the hindsi...

This paper presents the conception of a Smart Low Power Temperature Sensor which is powered using ambient vibration energy. It is presented the architecture of the conception of the sensor to be implemented. This power system will be the main part of the power stage for a self-powered micro temperature sensor inside a distributed sensor network where accessibility to human being operators is ve...

By having implemented digital terrestrial television (DTT) in Latin American countries and taking into account their ability to develop interactive services, new possibilities have been opened for improved connectivity in rural areas and those with difficult access by using applications that enable ubiquitous communication. In order to transfer the existing knowledge from Spain and Europe, the ...
