Background: Tooth avulsion is one of the most severe dental traumas which most often occur in children. When immediate replantation is not possible, storage in a proper media may lead to a prolonged survival rate. Aloe Vera is a cactus like plant with green, tapered leaves that are filled with a transparent viscous gel. This medicinal plant has significant anti-inflammatory, antioxidant, antiba...

We use a mathematical technique, the self-similar functional renormalization, to construct formulas for the average conductivity that apply for large heterogeneity, based on perturbative expansions in powers of a small parameter, usually the log-variance σ Y of the local conductivity. Using perturbation expansions up to third order and fourth order in σ Y obtained from the moment equation appro...

We study optimal paths in disordered energy landscapes using energy distributions of the type P(log(10) E)=const that lead to the strong disorder limit. If we truncate the distribution, so that P(log(10) E)=const only for E(min) < or =E < or =E(max), and P(log(10) E)=0 otherwise, we obtain a crossover from self-similar (strong disorder) to self-affine (moderate disorder) behavior at a path leng...

Propagation of deformation pulses in significantly nonlinear media with inner structure where there is no 1inea.r part in interaction force between neighboring structure elements is considered. This makes impossible the application of traditional wave equation or developed earlier approaches wherein nonlinearity serves as a small correction and requires the development of a qualitatively new no...

We here investigate polarimetric behavior of thick samples of porcine liver, Intralipid, and microsphere-based tissue phantoms whose absorption and scattering properties are matched. Using polarized light we measured reflection mode Mueller matrices and derived linear/circular/total depolarization rates, based on polar decomposition. According to our results, phantoms exhibit greater depolariza...

For several decades scholars have studied media reporting on scientific issues that involve controversy. Most studies so far have focused on the western world. This article tries to broaden the perspective by considering China and comparing it to a western country. A content analysis of newspaper coverage of vaccination issues in the UK and China shows, first, that the government-supported 'mai...

We analyze the time reversal of waves in a turbulent medium using the parabolic Markovian model. We prove that the time reversal resolution can be a nonlinear function of the wavelength and independent of the aperture. We establish a duality relation between the turbulence-induced wave spread and the time-reversal resolution which can be viewed as an uncertainty inequality for random media. The...

BACKGROUND Global Handwashing Day (GHD) is a handwashing promotion campaign organized by the Global Public-Private Partnership of Handwashing with Soap. In China, it has been promoted by the Chinese public health authorities, international organizations and multinational corporations through various channels including social media such as Sina Weibo, the leading Chinese microblogging site simil...

introduction: mass media influence the health behaviors of adolescents. evidence shows that traditional strategies such as censorship or limitation are no longer efficient; therefore, teaching media literacy is the best way to protect adolescents from harmful effects. the aim of this pilot study was to evaluate the effects of a media literacy training program on knowledge and behavioral intenti...
