Hydrogen Pressure as a Key Parameter to Control the Quality of the Naphtha Produced in the Hydrocracking of an HDPE/VGO Blend
(MDPI, 2022-05-16)
The hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) has been studied to assess the effect of H2 pressure on the yield and composition of the products and with the aim of obtaining ...
Stereoselective inverse conjugate addition of nitrogen and carbon nucleophiles to allenyl phosphine oxide. Synthesis of α,β-unsaturated phosphine oxides
(ARKAT USA, Inc, 2012)
[EN] The reactivity of new three carbon synthon, generated in situ from the reaction of electrondeficient allenes with an appropriate phosphine as the catalyst, toward pronucleophilic reagents is described. Triphenylphos ...

The Derivation of Dative Alternations
(John Benjamins Publishing Company, 2010)
[EN]This paper argues for an updated version of the classical derivational approach to Double Object Constructions (DOCs) and parallel dative construction across languages. We extensively argue that the arguments to postulate ...
Phosphorus substituted hydroxylamine and hydroxamic acid derivatives: synthesis and reactivity
(Arkat USA Inc, 2011)
[EN] This review summarizes several reports concerning the synthesis and synthetic applications of hydroxylamines derived from phosphines, phosphine oxides and phosphonates, and phosphorus substituted hydroxamic acid ...
Multiple table factor analysis applied to the higher education competences
(Purple Gate Publishing, 2012-04)
Due to the recent implantation of the Bologna
process, the definition of competences in Higher Education is an important matter that deserves special attention and requires
a detailed analysis. For that reason, we study ...
rhegf-Loaded Plga-Alginate Microspheres Enhance The Healing Of Full-Thickness Excisional Wounds In Diabetised Wistar Rats
(Elsevier, 2013)
[EN] Diabetic foot ulcers (DFUs) represent a major clinical challenge in the ageing
population. To address this problem, rhEGF-loaded Poly-Lactic-co-Glycolic-Acid (PLGA)-Alginate microspheres (MS) were prepared by a ...
