The standard method of curing industrial coatings has been accomplished by slow open air drying or somewhat faster gas heated convection air ovens. Electric infrared has also been used for curing paints for certain applications. While enhancing the rate of cure, the energy costs become excessive to operate. The introduction of gas fueled infrared catalytic thermoreactors is changing the way ind...

Plasmids are extrachromosomal pieces of double-stranded circular DNA which have the capability to replicate independently of the.Growth dynamics of multiple component communities of bacteria. Thus curing by acridines normally involves loss of the whole plasmid.Plasmids are extrachromasomally replicating molecules of DNA present in bacteria.Plasmid curing is a process of completely removing plas...

Background: Effective polymerization of the composite resin is essential to obtain long term clinical success and has a great importance obtaining improved mechanical properties. The purpose of this study was to measure the effect of the light intensity of LED and QTH curing devices in relation to the light distances, on the hardness (KHN) of two light cure nano-resin composite. Material and Me...

Background. Bulk-fill composite resins are a new type of resin-based composite resins, claimed to have the capacity to be placed in thick layers, up to 4 mm. This study was carried out to evaluate factors affecting gap formation in Cl II cavities restored using the bulk-fill technique. Methods. A total of 60 third molars were used in this study. Two Cl II cavities were prepared in each tooth, o...

In this paper, mechanical behavior of polyester with varying parameters of curing were investigated. Binder content, accelerator content, temperature and time were ascertained as parameters during curing of polyester specimens. Three levels of each parameter were selected and taguchi techniques are implemented. It was observed that curing time and binder content influenced mechanical properties...

Introduction An investigation of the chemical changes that take place in tobacco during curing is in progress at the Kentucky Agricultural Experiment Station. Attempts are being made to determine what the normal changes are and how they are influenced by such variables as temperature and relative humidity, which have been shown to influence the final quality of tobacco. A study of this type add...

In this paper, concrete specimens are immersed in ultrapure water, to study the evolutions of surface permeability, pore structure and paste microstructure following the prolonging of immersion period. According to the results, after 30-day immersion, the surface permeability of concrete becomes higher as compared with the value before immersion. However, further immersion makes the surface per...
