plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. people’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. this study aims to determine community’s perception of usage and disposal of plastic bags in eastern ethiopia. a quantitative cross-sectional study has been condu...

During neutron irradiation of metals, owing to the enhanced number vacancies and interstitial atoms, climb motion dislocations becomes significant at room temperature, leading a recrystallization material. Moreover, atoms tend form prismatic dislocation loops that play crucial role in plastic properties materials. X-ray peak profile analysis is an efficient nondestructive method determine micro...

The Swiss Plastic Surgery Association (https://plasticsurgery.ch/en/) decided to produce a corporate video to illustrate the concept of "plastic surgery of confidence" to the public. We show the diversity of specializations and the vast range of tasks that surgeons passionately handle day in and day out. We wanted to convey 2 main messages: first, that plastic surgery is more than just cosmetic...

Although the practice of medicine is built on a foundation of ethics, science, and common sense, the increasing complexity of medical interventions, social interactions, and societal norms of behavior challenges the ethical practice of aesthetic surgeons. We report a survey of the opinions, practices, and attitudes of experienced and novice facial plastic surgeons. The survey consisted of 15 cl...

The increasing interest in processing sequences of images motivates development of techniques for sequence-based object analysis and description. Accordingly, new velocity moments have been developed to allow a statistical description of both shape and associated motion through an image sequence. Through a generic framework motion information is determined using the established centralised mome...

We study, using direct orbit integrations, the kinematic response of the outer stellar disk to the presence of a central bar, as in the Milky-Way. We find that the bar’s outer Lindblad resonance (OLR) causes significant perturbations of the velocity moments. With increasing velocity dispersion, the radius of these perturbations is shifted outwards, beyond the nominal position of the OLR, but al...

Generalised color moments combine shape and color information and put them on an equal footing. Rational expressions of such moments can be designed, that are invariant under both geometric deformations and photometric changes. These generalised color moment invariants are effective features for recognition under changing viewpoint and illumination. The paper gives a systematic overview of such...

In the Maxwell interaction model the collision rate is independent of the relative velocity of the colliding pair and, as a consequence, the collisional moments are bilinear combinations of velocity moments of the same or lower order. In general, however, the drift term of the Boltzmann equation couples moments of a given order to moments of a higher order, thus preventing the solvability of th...
