BACKGROUND AND AIMS This experimental study mainly aims at comparing the most important mechanical properties of the new orthodontic archwires, those immersed in fluorinated solution, the as-retrieved ones and the intra-oral used ones. METHODS A total of 270 arch wires were tested, using tensile testing and three-point bending tests. The tested archwires were made of Stainless Steel, Nickel T...

Studies on first impressions from facial appearance have rapidly proliferated in the past decade. Almost all of these studies have relied on a single face image per target individual, and differences in impressions have been interpreted as originating in stable physiognomic differences between individuals. Here we show that images of the same individual can lead to different impressions, with w...

Physiognomy, the art of reading personality traits from faces, dates back to ancient Greece, and is still very popular. The present studies examine several aspects and consequences of the process of reading traits from faces. Using faces with neutral expressions, it is demonstrated that personality information conveyed in faces changes the interpretation of verbal information. Moreover, it is s...

Using a global database, we found that forest turnover rates (the average of tree mortality and recruitment rates) parallel broad-scale patterns of net primary productivity. First, forest turnover was higher in tropical than in temperate forests. Second, as recently demonstrated by others, Amazonian forest turnover was higher on fertile than infertile soils. Third, within temperate latitudes, t...

This study reports a case of climate-mediated transformation and physiognomic progression the Norway spruce (Picea abies) treeline ecotone since mid-1990s in Swedish Scandes. The methods include repeat photography foliation estimates old-established clonal spruces. An air soil temperature nadir by 1980s had caused extensive needle shoot mortality, evident at landscape-scale. Subsequent winter s...

Field investigation carried out by the Sicilian botanists in last 20 years enabled them to identify eight habitat types of high biogeographic and conservation interest, neglected Directive 92/43, which deserve ad hoc measures. For each these habitats, a syntaxonomic interpretation corresponding plant communities, their main ecological, physiognomic syndynamic traits list diagnostic species are ...

In any theocratic and monotheistic system, the female image is represented as a sexual entity, reduced to its most material physical dimension, avoiding intellectual or psychological peculiarity. The objective of following article describe analyze categorization, without modesty, women according their aptitude and, for this, we focus on physiognomic text bequeathed by Syrian writer al-Shayzarī ...
