INTRODUCTION The aims of this study were to evaluate dentin debris removal from the root canal during ultrasonic activation of sodium hypochlorite (2% and 10%), carbonated water, and distilled water and to determine the influence of 3 ultrasonic refreshment/activation cycles of the irrigant by using the intermittent flush technique. METHODS Root canals with a standardized groove in 1 canal wa...

Dental caries is an infectious disease involving all age groups. Adolescence is a period in which the risk for dental caries remains especially high. Many factors, some unique to the teenage years, contribute to the initiation and progression of dental caries in this age group. One factor with the potential for being significant is the adolescent diet, especially the high consumption of sugars....

F several of the largest supermarket product categories, such as carbonated soft drinks, canned soups, ready-to-eat cereals, and cookies, consumers regularly purchase assortments of products. Within the category, consumers often purchase multiple products and multiple units of each alternative selected on a given trip. This multiple discreteness violates the single-unit purchase assumption of m...

Carbonated and noncarbonated, sweetened blueberry flavored milks were evaluated by a trained panel. The effect of carbonation and sweetener type (sucrose, high fructose corn syrup, aspartame, and pear concentrate) on flavor properties was measured. Carbonation enhanced the sensory rating of overall flavor intensity, sweetness, and blueberry flavor. Sweetener type had a significant effect on the...

We conducted a novel study to capture the on-going advancement of mineral weathering within serpentinite formation by using an integrated approach multi-scale quantitative rock magnetic analyses and nano-resolution geochemical imaging analyses. studied suite samples from Coast Range Ophiolite Microbial Observatory (CROMO) in California conduct enabling us determine character Fe-bearing minerals...

Oxygen diffusion would not be important for healthy concrete. Once concrete is carbonated, however, oxygen diffusion is very crucial to lead reinforcement corrosion. Therefore, oxygen is always a potential threat of reinforcement corrosion in concrete and oxygen diffusivity is a material parameter for service life determination and durability designing of the concrete. One of the simple approac...

Deep extensions of low seismic velocities in the mantle beneath volcanic centers are commonly attributed to high temperatures and have been used as a possible characteristic of hot plumes originating at the core-mantle boundary. To address this issue, we examine the effect of volatiles on melting to determine if regions of low seismic velocities may also be interpreted as regions of melting wit...

The perception of carbonation is an important factor in beverage consumption which must be understood order to develop healthier products. Herein, we study the effects carbonated water on oral lubrication mechanisms involved mouthfeel and hence taste perception. Friction was measured a compliant PDMS-glass contact simulating tongue-palate interface (under representative speeds loads), while flu...
