We have established a reversible, pH-responsive release system for the antiseptic agent chlorhexidine. This system can be triggered by the acidic milieu present in infections of acid-producing bacteria, which play an important part during the formation of secondary caries and inflammations in the oral cavity.
The crystallite size of the Z-Fe3O4 NC was calculated as 27.23 nm using Scherer's equation (equation ()), at the 2θ peak position of 29.98°, a wavelength of λ = 1.54178 nm, and a shape factor of K = 0.94.Scherer's equation is given as follows: where is the wavelength of X-ray (CuKα), is the full width at half maximum, θ is the Bragg's Angle, and L is the crystallite size.

The role of polyamine (PA) metabolism in tobacco ( Nicotiana tabacum ) defense against pathogens with contrasting pathogenic strategies was evaluated. Infection by the necrotrophic fungus Sclerotinia sclerotiorum resulted in increased arginine decarboxylase expression and activity in host tissues, as well as putrescine and spermine accumulation in leaf apoplast.

Several gases could be used in floatation, however, due to the availability and cost, air is the most commonly used gas [33, 34].Nevertheless, in certain applications where the presence of oxygen is unfavorable, other gases could be used such as methane, carbon dioxide and nitrogen .The most popular floatation techniques are the dissolved gas floatation and the induced gas floatation .
In plants, the protein RPM1-INTERACTING PROTEIN4 (RIN4) is a central regulator of both pattern-triggered immunity and effector-triggered immunity. RIN4 is targeted by several effectors, including the Pseudomonas syringae protease effector AvrRpt2. Cleavage of RIN4 by AvrRpt2 generates potentially unstable RIN4 fragments, whose degradation leads to the activation of the resistance protein ...

The present invention relates to a process for covering a substrate with a polymer film characterized in that, prior to the deposition of said polymer film, nanoparticles are adsorbed electrostatically onto the surface of said substrate to be covered.
8/1/2009· Objectives: Through the understanding of tooth enamel science and insights into the beneficial role calcium can play in the caries process, a novel fluoride toothpaste has been developed containing micro‐calcium. This paper describes a series of in vitro studies to assess delivery of the micro‐calcium to a plaque biofilm, delivery of radiolabelled micro‐calcium to subsurface enamel ...
Abstract. Arsenic (As) is a harmful metalloid that can be naturally found in soils and water. Consumption of contaminated groundwater is the most common source of human poisoning; furthermore, the ingestion of contaminated food is currently getting much attention.
The building sector is one of the dominant energy consumers with a total of 30% share of the world energy consumption in 2013 and is also responsible for one-third of the greenhouse gas emissions around the world, .This share particularly is on the higher side in developed countries, for example in U.S. in 2011, it accounts for 41% share of primary energy .

4/7/2020· The WRG mineral wool and perlite A samples fail much more catastrophically than the perlite B sample or, for that matter, the Pyrogel XT sample, which hasn't failed at all after 200 days. The WRG quickly soars to its saturation value of 855% uptake after 10 days exposure. The perlite A sample degrades to 264% uptake after 16 days.
The performance of the material is determined by its structure, i.e., the composition of the material elements of the atomic structure, the molecular structure, and atoms or molecules in space arrangement and the aggregation characteristics. The microstructure of the material has important implications for the material performance. In this paper, five phase change materials, potassium nitrate ...
Substituting in the formula, we have: E m = 500 ÷ 1,000 + 45 ÷ 200 + 40 ÷ 200 E m = 0.500 + 0.225 + 0.200 E m = 0.925 Since E m is less than unity (1), the exposure combination is within acceptable limits. (e) To achieve compliance with paragraphs (a) through (d) of this section, administrative or engineering controls must first be determined and implemented whenever feasible.
