The orbital motion around a central body is an interesting problem that involves the theory of artificial satellites and the planetary theories in the solar system. Nevertheless some difficult situations appear while ...
[EN] Ti 6Al 4V and Cr Co alloys are extensively used in manufacturing prostheses due to their biocompatibility, high strength-to-weight ratio and high resistance to corrosion and wear. However, machining operations involving ...
[EN] The use of archetypal analysis is proposed in order to determine a set of representative cases that entail a certain percentage of the population, in the accommodation problem. A well-known anthropometric database has ...
[EN] A series of C2 symmetrical 1:2 Ni:L complexes derived from a-amino amides were studied for the enantioselective addition of dialkylzinc reagents to aldehydes. Different structural elements on the ligands seem to play ...
[EN] This work presents an experimental evaluation, from an energy analysis point of view, for two of the most used inter-stage systems in two-stage vapour compression cycles driven by compound compressors: the direct ...

[EN] The authors have realized that the proof of Step 1 in [1, Theorem A] is incomplete.
Precisely, in the proof of Step 1 we suppose that there exists a p-element x of index m
where p is the set of primes dividing m and ...
