In this paper, a uniformly elliptic second order boundary value problem in 2D is discretized by the p-version of the finite element method. An inexact Dirichlet-Dirichlet domain decomposition pre-conditioner for the system of linear algebraic equations is investigated. The ingredients of such a pre-conditioner are an pre-conditioner for the Schur complement, an preconditioner for the sub-domain...

BACKGROUND Despite widespread clinical uses of resin-modified glass-ionomers (RMGIs), their sealing ability is still a concern. This study evaluated the effect of delayed light activation (DLA) of RMGI on marginal sealing in differently pretreated cavities. MATERIALS AND METHODS In this in vitro study, two standardized Class V cavities were prepared on the buccal and lingual surfaces of 56 so...

in this study, the performance of a fabricated fluffer was evaluated and compared with common field curing methods for alfalfa. the drying rate, baling loss and alfalfa nutrient value (dry matter and crude protein) were the criteria for evaluation. the alfalfa was cut using a mower-conditioner. a randomized complete block experimental design was used with three treatments (fluffing swathed alfa...

Feedback is a very powerful concept and has numerous applications. Examples of feedback systems abound in everyday life. For example, the thermostat on an air conditioner unit uses feedback to maintain a comfortable temperature within a room. Similiarly, our bodies use feedback to increase antibodies to fight off an infection. By definition, feedback is the process of combining the output of a ...

The purpose of this study was to examine the feasibility of a conditioner for treating enamel and dentin simultaneously for MMA-TBB resin bonding. Various phosphoric acid solutions containing copper salts were prepared and used as conditioners before bonding MMA-TBB resin to bovine teeth. Their effects on the surface morphology and bonding were studied by scanning electron microscopy and tensil...

In this paper, we describe implementation and test result for a LonWorks based control system in which air conditioner is handled by LonWorks node. The LonWorks based control system for handling air conditioner remotely is integration of control nodes because LonWorks is a communication protocol which is adopted as a standard protocol in building automation systems. For the remote management of...

This study evaluated the antifungal, physical, and mechanical properties of tissue conditioner incorporated with different amounts zinc oxide nanoparticles (ZnOnps) at storage times (0, 7, 14 days). Specimens 0, 5, 10, 15 wt% ZnOnps, or nystatin into were fabricated (control, 5Zn, 10Zn, 15Zn, Nys). The direct contact test (n=6) was performed to evaluate antifungal effect against C. albicans sus...

Despite the known difficulties many people with MS have with high ambient temperatures, there are no reported studies of air conditioning use and MS. This study systematically examined air conditioner use by Australians with MS. A short survey was sent to all participants in the Australian MS Longitudinal Study cohort with a response rate of 76% (n = 2,385). Questions included hours of air-cond...
