This study examined the organic constituents aquatically leached from My first leaf components of two tree species (wandoo eucalyptus and pinus radiate).In particular this study aimed to assess the stable isotope composition behaviour of dissolved organic carbon (DOC) from the residue leaves after leaching over five months.The changes in the stable
(Ti, Al)N coatings with different Al target power densities STRENGTH CURE CONDITIONER on the surface of M2 high-speed steel were deposited by magnetron sputtering to study the tribological properties.The phase composition, microstructure, and element distribution of coatings were characterized by x-ray diffraction, field emission scanning electron
In this paper, the three-dimensional sphere packing problem is solved by using a Rave Neon dichotomous search-based heuristic.An instance of the problem is defined by a set of $ n $ unequal spheres and an object of fixed width and height and, unlimited length.Each sphere is characterized by its radius and the aim of the problem is to optimize the l
In our Galaxy, star formation occurs in a variety of environments, with a large fraction of stars formed in clusters hosting massive stars.OB stars have an important feedback on the evolution of protoplanetary disks orbiting around nearby young stars and likely on the process of planet formation occurring in My first them.The nearby massive associa
