Total catalytic wet oxidation of phenol and its chlorinated derivates with MnO2...
Luna,A. J.; Rojas,L. O. A.; Melo,D. M. A.; Benachour,M.; Sousa,J. F. deIn the present work, a synthetic effluent of phenol was treated by means of a total oxidation process-Catalyzed Wet Oxidation (CWO). A mixed oxide of Mn-Ce (7:3), the catalyst, was synthesized by co-precipitation from an aqueous solution of MnCl2 and CeCl3 in a basic medium. The mixed oxide, MnO2/CeO2, was characterized and used in the oxidation of phenol in a slurry reactor in the temperature range of 80-130ºC...
Niobium carbide synthesis by solid-gas reaction using a rotating cylinder reactor
Fontes,F. A. O.; Gomes,K. K. P.; Oliveira,S. A.; Souza,C. P.; Sousa,J. F.A rotating cylinder reactor was designed for the synthesis of niobium carbide powders at 1173 K. Niobium carbide, NbC, was prepared by carbothermal reduction starting from commercial niobium pentoxide powders. The reactor was heated using a custom-made, two-part, hinged, electric furnace with programmable temperature control. The design and operational details of the reactor are presented. The longitudinal temp...
Differential expression of integrin subunits on adherent and nonadherent mast c...
Grodzki,A.C.G.; Dávila Pástor,M.V.; Sousa,J.F.; Oliver,C.; Jamur,M.C.Mast cell progenitors arise in bone marrow and then migrate to peripheral tissues where they mature. It is presumed that integrin receptors are involved in their migration and homing. In the present study, the expression of various integrin subunits was investigated in three systems of adherent and nonadherent mast cells. Mesentery mast cells, freshly isolated bone marrow-derived mast cells (BMMC) and RBL-2H3 c...
Genetic Algorithms for the bus driver scheduling problem : a case study
T. G. Dias; J. P. de Sousa; J. F. CunhaThis paper describes an application of genetic algorithms to the bus driver scheduling problem. The application of genetic algorithms extends the traditional approach of Set Covering / Set Partitioning formulations, allowing the simultaneous consideration of several complex criteria. The genetic algorithm is integrated in a DSS but it can be used as very interactive tool or a stand-alone application. It incorpo...
The DNA puff BhB10-1 gene is differentially expressed in various tissues of Bra...
Monesi,N.; Sousa,J.F.; Paçó-Larson,M.L.We extended the characterization of the DNA puff BhB10-1 gene of Bradysia hygida by showing that, although its mRNA is detected only at the end of the fourth larval instar, BhB10-1 expression is not restricted to the salivary gland, the tissue in which this gene is amplified. Different amounts of BhB10-1 mRNA were detected in other larval tissues such as gut, Malpighian tubules, fat body, brain and cuticle, sug...
Psicodinâmica de doentes com galactorreia com e sem tumor da hipófise
Sobrinho, Luis Gonçalves; Sousa, J. F.; Henriques, E. F; Silva, M. C.; Matos, M. J.; Grilo, A.; Santos, M. A.( I ) A psicodinamia de 19 doentes com galactorreia foi avaliada através de entrevistas longas e repetidas, individuais e em grupo, por três pessoas com treino analítico (dois psicoterapeutas e um endocrinologista). (2) Destas doentes, sete tinham tumor da hipófise. Tiveram ainda estas doentes um estudo endócrino e radiográfico completo e uma avaliação psicométrica. (3) Encontrou-se em todas as dezanove doentes...
Nephrotic syndrome. What is new since the 1988 study?.
Seves, M G; Serviço 2, Unidade de Nefrologia, Hospital de Dona Estefânia, Lisboa.; Brito, M J; Lamy, S; Luiz, P V; Bastos, G; Faleiro, M; Batista, JThe authors make a retrospective review of 53 new cases of Nephrotic Syndrome followed up in the Nephrology Unit from November 1988 to March 1994, bearing in mind the evaluation of casual changes of the disease standard regarding a previous study of 1988. Epidemiological, clinical, therapeutical and evolutional aspects were studied. Forty-four cases of primary Nephrotic Syndrome (83%) were identified, 61.4% of ...
Renal dysplasia: clinico-pathologic review.
Cunha, A S; Laboratório de Anatomia Patológica, Escola Superior de Medicina Dentária de Lisboa, Hospital de D. Estefânia.; de Sousa, J F; Garcia, CHistology records from 63 nephrectomies were reviewed; 22 patients had unilateral totally dysplastic kidneys and 5 had polar or segmental dysplasia. A clinicopathological study of these cases was undertaken. In the first group, there was a slight male preponderance and 75% of the patients presented were under two years of age. Urinary tract infection was the most common complaint. 4 patients were diagnosed in u...
