Malignant melanoma is one of the most aggressive malignancies in human and is responsible for almost 60% of lethal skin tumors. Its incidence has been increasing in white population in the past two decades. The disease was classified by Clark and coworkers

accuracy of 0.01 mg is isolated from the reaction chamber and the aggressive purge gas, which allows the chamber to be completely sealed. Approximately 200 mg sample was placed in the alumina holder and outgassed at 150 °C for 30 min under N 2 at 500 mL

arrangement of the clay mineral lamellae. Pronounced HCl concentrations turned out to be quite aggressive towards the most reactive fraction of bentonite structure. This is well argued by the progressive decay of the specific XRD lines of montmorillonite

the emission of fume and toxic or chemical aggressive volatile products during the combustion of polymeric materials [ 6 – 8 ]. In recent years, a considerable attention has been paid to polymeric nanocomposites because they show a higher thermal

highly aggressive reagents in a minimum amount of solvent (AlCl 3 in propionyl chloride and neat ICl), in combination with high-temperature operation, allowed the completion of the whole reaction sequence with unprecedented speed in an overall yield of

Introduction Cracking in the early age concrete often results from restrained volume changes due to temperature change during the hydration. Cracking may reduce the concrete durability against aggressive substance as well as
