Moisture contamination is a major factor in sealant application, often determining clinical success or failure. A new enamel conditioner using HNO3 (2.5%) has been introduced that does not require a water rinse after etching. The aim of this study is to compare etching characteristics using sealant retention from shear bond strength tests for traditional etch conditioning using H3PO4 (37%) and ...

Debris flows are fast mass movements formed by a mix of water and solid materials, which occur in steep torrents, and are a source of high risks for human settlements. Geophones are widely used to detect the ground vibration induced by passing debris flows. However, the recording of geophone signals usually requires storing a huge amount of data, which leads to problems in storage capacity and ...

As a result of increasing environmental temperature, use air conditioner (AC) has become very popular specially in the urban areas mostly during warmer months year. Exposure to cold, dry AC on regular basis can cause various alternations lung functions users which lead many future diseases. These be influenced by temperature at is regulated. This cross-sectional study was conducted observe effe...

In this paper, the simulated performance of a number of differentiated services traffic conditioners is studied under a range of synthetic traffic conditions. The traffic conditioners are compared using two performance measures which are defined and justified in the paper. In the initial simulation the traffic conditioner performance differed in one measure but not the other. Further experiment...

Program conditioning consists of identifying and removing a set of statements which cannot be executed when a condition of interest holds at some point in a program. It has been applied to problems in maintenance, testing, re–use and re–engineering. Program conditioning relies upon both symbolic execution and reasoning about symbolic predicates. Automation of the process therefore requires some...
