Quantitative polarity scales have been of great value in advancing our understanding of chemical and physical processes in bulk solvents. However, an understanding of the polarity at liquid interfaces has been more elusive and no scale of interface polarity currently exists. Following our demonstration that second harmonic spectroscopy can be used to measure interface polarity, we have determin...
New approaches to extracting natural hydroxyl carbonate apatite from bio waste of bovine bones cortical femur have been developed. To extract pure and natural bio ceramics, three different treatments have been applied: 1-Calcination heat treatment at temperature of 700 , 2-alkaline hydrothermal at temperature of 275 and 3-Pressurized low polarity water at temperature of 250 . Raw bovine bone an...
INTRODUCTION The atrial activation sequence around the tricuspid annulus has been used to assess whether complete block has been achieved across the cavotricuspid isthmus during radiofrequency ablation of typical atrial flutter. However, sometimes the atrial activation sequence does not clearly establish the presence or absence of complete block. The purpose of this study was to determine wheth...

Opinion mining is a well-known problem in natural language processing that has attracted increasing attention in recent years. Existing approaches have been often focused on identifying direct opinions and ignored indirect ones. However, in some domains such as medical, indirect opinions occur frequently. Therefore, ignoring indirect opinions can lead to the loss of valuable information and not...
In this paper we present SABRINA (Sentiment Analysis: a Broad Resource for Italian Natural language Applications) a manually annotated prior polarity lexical resource for Italian natural language applications in the field of opinion mining and sentiment induction. The resource consists in two different sets, an Italian dictionary of more than 277.000 words tagged with their prior polarity value...
The absence of negative universal determiners in natural languages expressing “not all” has given rise to various speculations, ranging from an innate principle of grammar to blocking on the basis of pragmatic principles. After arguing that these proposals are flawed, I propose that there are no general principles standing in the way of such determiners, but that the two main processes which di...
