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...

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...

This study evaluated the effect of dentin surface treatment on shear bond strengths of two light- cured glass ionomer restorative materials to dentin. Cylinders of Fuji II LC and VariGlass VLC were bonded to dentin surfaces that were untreated, treated with a 10% polyacrylic acid (GC Conditioner), or treated with a dentin bonding agent primer (Prisma Universal Bond 3 Primer). Specimens were the...

The adjustment and control mode of frequency conversion for an air-conditioner can make the refrigeration capacity adapt the variety of its load very well. Thus, it has many advantages such as low variety in in-door temperature, short time to reach the wished temperature, low energy consumption, low start electric current and low strike to electric source etc. This mode is widely used in room a...

The purpose of this study is to develop a circuit for an automobile air conditioner, which will reduce the consumption power developed by engine. This paper proposes design absorption conditioner. A description principle operation conditioner operating on cycle one-stage refrigeration machine has been given in paper. It consists stripper (generator), condenser, absorber, evaporator. Lithium bro...

BACKGROUND Denture stomatitis is a common oral lesion following the use of ill-fitting dentures. A layer of tissue conditioner is usually used to improve adaptation of the denture. These liners can support the in vivo adhesion and colonization of the oral Candida. The aim of this study was to evaluate the efficacy of the two common antifungal agents mixed with tissue conditioner against Candida...

To identify effective regulatory methods scheduling with the compromise between the soil desalination and the improvement of tomato quality and yield, a 3-year field experiment was conducted to evaluate and compare the effect of straw mulching and soil structure conditioner and water-retaining agent on greenhouse saline soils, tomato quality, and yield. A higher salt removing rate of 80.72% in ...

Rapid fermentation of food waste can be used to prepare soil conditioner. This process consumes less time and is more cost-effective than traditional preparation technology. However, the succession of the soil microbial community structure after long-term application of rapid fermentation-derived soil conditioners remains unclear. Herein, dynamic rapid fermentation (DRF) of food waste was perfo...

Major noise sources of a home air conditioner are fan and compressor. Fan generates air flow noise main& and compressor is the main source of the vibration induced noise. In this study, finite element analysis, a method for design of experiment and a topology optimization method were used to find optimum shape of rubber mount, copper pipe and compressor base plate of a home air conditioner. For...
