Decorative crystal gel balls are used for decoration purpose. Due to their attractive appearance they may be ingested by children. This may result in grave complications. A case of decorative crystal ball ingestion is being reported in a 6 months old infant who presented with sub acute intestinal obstruction and was operated. Crystal gel balls were causing obstruction of jejunum. Enterotomy and...

We demonstrate the existence of a novel superconducting state in high quality two-component MgB2 single crystalline superconductors where a unique combination of both type-1 (lambda{1}/xi{1}<1/sqrt[2]) and type-2 (lambda{2}/xi{2}>1/sqrt[2]) superconductor conditions is realized for the two components of the order parameter. This condition leads to a vortex-vortex interaction attractive at long ...

– Systems with two species of active molecular motors moving on (cytoskeletal) filaments into opposite directions are studied theoretically using driven lattice gas models. The motors can unbind from and rebind to the filaments. Two motors are more likely to bind on adjacent filament sites if they belong to the same species. These systems exhibit (i) Continuous phase transitions towards states ...

This study aims to compare the perception of smile esthetics, under various conditions, among general and specialist dentists. Materials and Methods: A photograph of a woman&rsquo;s smile was digitally altered using a software image editing program. Alterations were made tothe dental midline, anterior gingival displ...

Introduction: Giotto (1266–1337) and his workshop realized c. 1315 the large Crucifix now in the Louvre Museum. The conservation of this masterpiece in 2010–2013 in the C2RMF studios gave the opportunity for a comprehensive investigation of the execution technique through a characterization of the paint layers. The first examinations revealed an original gilding and decoration surrounding the C...

In the foreign exchange market, time-varying transaction costs and interest rates may define set of attractive currencies for investors. Our study shows that when are attractive, they tend to deviate from uncovered rate parity comove with global stochastic discount factor (SDF). Inversely, non-attractive, conform more closely do not SDF. As a consequence, both investors policy makers want know ...

Previous studies have suggested several adaptive functions for the decorated tube caps of Diopatra cuprea (Polychaeta: Onuphidae). We experimentally tested the hypothesis that decoration provides crypsis. A series of field experiments quantified predation-related damage done to tube caps that were (1) devoid of decoration, (2) decorated with algae, or (3) decorated with shell fragments. If deco...
