Objectives The aim was to evaluate dentinal crack formation after root canal preparation with ProTaper Next system (PTN) with and without a glide path.Materials and Methods Forty-five mesial roots of mandibular first molars were selected.Fifteen teeth were left unprepared and served as controls.The experimental groups consist of mesiobuccal and mes
We have studied the spatial and temporal variation of the surface longwave radiation (downwelling and net) over a 21-year period in the tropical and subtropical Pacific Ocean (40 S–40 N, 90 E–75 W).The fluxes were computed using a deterministic model for atmospheric radiation transfer, along with satellite data from the ISCCP-D2 databas
There have been many studies that have attempted to address the complexity underlying manufactured ceramic assemblages after the conquest of Rome.So much so that today it is possible to easily find a great amount of typological lists, which mostly help to clearly establish linear Telford Raiders temporal sequences.A reality that is most probably ve
Human metapneumovirus (HMPV) is an important cause of upper and lower respiratory tract disease in individuals of all ages.It is estimated that most individuals will be infected by HMPV by the age of five years old.Despite this burden of disease, there remain caveats in our knowledge of global genetic diversity due to a lack of HMPV sequencing, par
Abstract The perceived and real threat of shark bites have significant direct health and indirect economic impacts.Here we assess the changing odds of surviving an unprovoked shark bite using 200 years Skirting Clips of Australian records.Bite survivability rates for bull (Carcharhinus leucas), tiger (Galeocerdo cuvier) and white (Carcharodon carch
