This paper presents a detailed study of the damages and collapses suffered by various masonry churches in aftermath seismic sequence Central Italy 2016. The will first be analyzed then compared with numerical data obtained through 3D simulations eigenfrequency nonlinear static analyses (i.e., pushover). main purposes this are: (i) to create an adequately consistent sensitivity on several defini...

Clear dental aligners are used for treating orthodontic anomalies (misaligned teeth, inappropriate contact between upper and lower teeth etc.), minor irregularities bruxism. Using additive manufacturing technologies clear made of biocompatible photopolymer, using a vat photopolymerization technology. One problems in application is the change aligner material properties after production, includi...

In recent years there has been considerable development in the area of system reliability assess-ments of offshore structures except for jack-up platform. However, since the reliability of jack-up platform is acrucial aspect with regard to the safety of the structure during its service time and possibly beyond the predictedlifetime, there is significant demand from the offshore indu...

Since 1994, at least six major (volume >10m) ice and rock avalanches have occurred on Iliamna volcano, Alaska, USA. Each of the avalanches was preceded by up to 2 hours of seismicity believed to represent the initial stages of failure. Each seismic sequence begins with a series of repeating earthquakes thought to represent slip on an ice–rock interface, or between layers of ice. This stage is f...

BACKGROUND Biofilm production has been established as a virulence factor which allows Staphylococcus to adhere and persist in medical devices. The objective was to determine whether therapeutic failure in patients infected with Staphylococcus spp. is linked to biofilm production, the presence of the ica operon, and the bacterial insertion sequence element IS256. METHODS Staphylococcus spp. is...
