Gamelas, Carla A.; Neves, P.; Gomes, Ana C.; Valente, Anabela A.; Romão, Carlos C.; Gonçalves, Isabel S.; Pillinger, M.Resumo alargado de "Molybdenum(II) Diiodo-Tricarbonyl Complexes Containing Nitrogen Donor Ligands as Catalyst Precursors for the Epoxidation of Methyl Oleate"
Mesoporous carbon as an efficient catalyst for alcoholysis and aminolysis of ep...
Matos, I; Neves, P; Castanheiro, J; Perez-Mayoral, E; Martin-Aranda, R; Duran-Valle, C; Vital, J; Botelho do Rego, A; Fonseca, IThe ring opening reaction of epoxides by alcohols and amines using mesoporous activated carbon as efficient and environmentally friendly heterogeneous catalyst is reported. Carbon xerogels were synthesized by polymerization of resorcinol and formaldehyde. The surface of the activated carbon was oxidized in liquid phase with HNO3 and then functionalized with H2SO4. Chemical and textural characterization by eleme...
Morphological characteristics of ovarian development of two Nile tilapia (Oreoc...
Neves,P.R.; Natali,M.R.M.; Ribeiro,R.P.; Vargas,L.; Maehana,K.R.; Marengoni,N.G.This study was carried out to morphologically characterize and classify the stages of gonad development in different Nile tilapia strains (Oreochromis niloticus). Eighty-four and ninety-two ovaries from Bouaké and Chitralada strains, respectively, were evaluated at different ovarian developmental phases: initial (104 days of culture), intermediate (152 days of culture), and the final (279 days of culture). The ...
Pattern of functional antibody activity against Haemophilus influenzae type b (...
Matos,D.C.S.; Silva,A.M.V.; Neves,P.C.C.; Martins,R.M.; Homma,A.; Marcovistz,R.We evaluated the functional activity of Haemophilus influenzae B (Hib) antibodies elicited in a group of infants immunized with the diphtheria-tetanus-pertussis vaccine combined with an Hib vaccine produced totally in Brazil after technological transfer of Hib vaccine production from Glaxo SmithKline, Belgium. Blood samples from immunized infants (N = 985) were collected for the determination of Hib antibodies....

A new experimental technique for positive ion drift velocity measurements in no...
Neves, P. N. B.; Conde, C. A. N.; Távora, L. M. N.A new technique is described for measuring the drift velocities and mobilities of noble gas ions in noble gases that makes use of a gaseous electron multiplier (GEM) and a UV flash lamp to produce the ions in a thin, well-defined, planar region. The drift velocities are determined from measurements of the transit time of the ions in crossing the drift space. We present experimental results for xenon ions in xen...
