OBJECTIVE to evaluate the association between psychological demands, control over the work and the reduction of work ability of nursing professionals. METHOD this cross-sectional study involved 498 nursing professionals of a university hospital in the State of Rio Grande do Sul, Brazil. Data collection was carried out in 2009 using the Brazilian versions of the Work Ability Index and Job Stre...

Effluent discharge from septic tanks is affecting the environment in developing countries. The most challenging issue facing these countries is the cost of inadequate sanitation, which includes significant economic, social, and environmental burdens. Although most sanitation facilities are evaluated based on their immediate costs and benefits, their long-term performance should also be investig...

The single-column mode (SCM) of the ICON (ICOsahedral Nonhydrostatic) modeling framework is presented. primary purpose SCM to use it as a tool for research, model evaluation and development. Thanks simplified geometry SCM, various aspects model, in particular physics, can be studied well-controlled environment. Additionally, has reduced computational cost low data storage demand. utilized ideal...

Reading a formal proof script written in a procedural (command-driven) style is difficult, bordering on impossible, without access to an interpreter for the script, that generates the states based on the commands. The Proviola system replaces the need for this interpreter, storing responses and displaying them on-demand. This abstract describes a natural extension to the Proviola: instead of wo...

background: nickel-titanium (ni-ti) rotary instrument files are important devices in endodontics in root canal preparation. ni-ti file breakage is a critical and problematic issue and irrigation techniques were applied to decrease risk of file failure root. the aim of the present study was to compare the temperature gradient change of different irrigation solutions with ni-ti rotary instrument ...

An architecture is presented for a digital signal processor (DSP) intended for use in digital mobile phones. In this application, it is necessary to balance the requirement of high processing throughput with the demand of low power for extended battery lifetime. These requirements are addressed by a multi-level power reduction strategy, involving the use of a parallel asynchronous architecture,...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. Wi...

Production of high quality digital media is increasing in both the commercial and academic world. This content needs to be distributed to end users on demand and efficiently. Initiatives like CineGrid [1] push the limit looking at the creation of content distribution centres connected through dedicated optical circuits. The research question of this project is the following: “What is the optima...

Traditional collection management of serials through site licenses and subscriptions is increasingly unsustainable due to rising costs and steady or falling library budgets. The ensuing gaps in access have led to widespread illicit file sharing, resulting in the disintermediation of libraries and the devaluing of publishers. It has therefore become essential to explore alternatives for the deli...
