Spiropyrimidines vanquish a significant situation in the field of heterocyclic chemistry, they are broadly utilized as an antibacterial, an inhibitor of multidrug opposition, or an antiplatelet and antithrombotic drug. Phosphate, the principal moroccan mineral wealth occupies a vital spot in the economic sector and its valuation is a goal continually looked for. Among the conceivable outcomes of valorization, its utilization in heterogeneous catalysis which thought about an exceptionally encouraging new way. In this context, the focus on the reaction of the synthesis of spiropy-rimidine, catalyzed by natural phosphate (NP) and by fluoroapatite (Fap), are used alone or doped by cobalt. These phosphate catalysts were characterized by XRd, IR and SEm, while the synthesized spiropyrimidine was identified by IR, GC-mS and NmR. The obtained yield with fluorapatite doped by cobalt (Co/Fap), at room temperature in ethanol is very high and shows a high impact performance induced by a synergistic effect compared to that of NP alone.

We survey contemporary studies of hadrons and strongly interacting quarks using QCd's dyson-Schwinger equations, addressing the following aspects: confinement and dynamical chiral symmetry breaking; the hadron spectrum; hadron elastic and transition form factors, from small-to large-Q2; parton distribution functions; the physics of hadrons containing one or more heavy quarks; and properties of the quark gluon plasma.

The compound （1 z）-2-（hydroxymethyl）-dodec-1-ene-1,3-diol was previously isolated from the integument of the red palm weevil Rhynhophorus ferruginous and found to antagonize calcium chloride induced dysrrhythmia in mice. Further calcium-dependent pharmacological actions performed in this study revealed that it has the ability to inhibit platelets aggregation induced in guinea pigs with either AdP or archegonia acids, and the compound also decreased the arterial pressure in rats in a dose-dependent manner and exerted potential ant consultant activity in mice against pentylene tetrazole-induced seizures. However, no complete protection was observed. Analgesic studies in mice using the hot plate （58 ℃） revealed its potential analgesic activities. Its effective dose 50 （ed50） was 85.7 ± 6.3 mg/kg （N= 5）. The compound seamed to produce all of the above actions via a calcium antagonistic action.

From the definition of the standard Perelomov coherent states we introduce the Perelomov number coherent states for any su(2) Lie algebra. With the displacement operator we apply a similarity transformation to the su(2)generators and construct a new set of operators which also close the su(2) Lie algebra, being the Perelomov number coherent states the new basis for its unitary irreducible representation. We apply our results to obtain the energy spectrum, the eigenstates and the partition function of two coupled oscillators. We show that the eigenstates of two coupled oscillators are the SU(2) Perelomov number coherent states of the two-dimensional harmonic oscillator with an appropriate choice of the coherent state parameters.
