Following the recent publication of the PRAMI trial, the appearance of the article entitled ‘‘Multivessel approach in ST-elevation myocardial infarction: Impact on in-hospital morbidity and mortality’’ by Santos et al. in this issue of the Journal could not be more timely. The study analyzed a population of patients with ST-elevation myocardial infarction (STEMI) included in the Portuguese Regi...

13 A large number of the bridges in the European railway networks are metallic bridges. 14 The increasing volume of traffic and axle weight of trains mean that for many 15 structures the loads today are much higher than those envisaged when they were 16 designed. This paper presents a summary of the different recommendations and 17 advices proposed in “Guidelines for Load and Resistance Assessm...

Abstract Bridge inspections are relied heavily on visual inspection, and usually conducted within limited time windows, typically at night, to minimize their impact traffic. This makes it difficult inspect every meter of the structure, especially for large-scale bridges with hard-to-access areas, which creates a risk missing serious defects or even safety hazards. paper presents new technique s...

It has been suggested that population growth dynamics may be revealed by the geographic distribution and the physical structure of ancient bridges. Yet, this relationship has not been empirically verified. In this study, we applied the archaeological records for ancient bridges to reveal the population growth dynamics in the lower Yangtze River Basin in late imperial China. We investigated 89 a...

The Saccharomyces cerevisiae spore wall is a multilaminar coat that surrounds individual spores and protects them from environmental insult. Scanning electron microscopy reveals that the four spores of an ascus are connected by interspore bridges. Transmission electron microscopy of spores indicates that these bridges are continuous with the outer layers of the spore wall. In chs3 mutants, whic...

The number, morphometric parameters and amount of aminergic neurosecretory product of protocerebral A2 neurosecretory neurons were investigated in the fifth instar of Lymantria dispar caterpillars, following a suitable or unsuitable trophic regime. Caterpillars originated from two populations (Quercus rubra or Robinia pseudoacacia forest) and were differently adapted to trophic stress, i.e. fee...
