É objectivo deste artigo explorar a ideia de teatro que os textos de crítica teatral de Fernando Amado encerram ou ajudam a revelar. Para tal, importará dar conta do momento de renovação cénica e actualização cultural, de que a segunda metade dos anos quarenta é expoente, e das relações que o ideário formado por Fernando Amado, Redondo Júnior ou Gino Saviotti, entre outros, pode estabelecer com o que pela Europa Teatral se vai apelidando de teatro moderno.

Tomando como ponto de partida o movimento de teatro experimental português do pós-Segunda Guerra Mundial, a presente investigação centra-se no trajecto da Casa da Comédia, fundada por Fernando Amado em 1946, e que retoma a actividade em 1962. Procuramos identificar as ideias de teatro que animam o percurso deste grupo, dar eco da recepção aos seus espectáculos, bem como inserir o seu projecto no âmbito dos esforços de renovação cénica que vão tendo lugar um pouco por toda a Europa.

Com o objetivo de determinar a prevalência da infecção pelo Citomegalovírus (CMV) em pacientes com AIDS, bem como relacionar os achados clínico-virológicos decorrentes desta infecção com as repercussões anatomopatológicas, estudamos 50 pacientes adultos atendidos entre abril de 1986 a junho de 1987, em dois hospitais públicos de São Paulo (HSP e HSPE). Estes pacientes foram acompanhados clínica e laboratorialmente, por período médio de 2 meses com coletas seriadas de sangue, urina e saliva. Foram realizados isolamento do CMV em monocamadas de fibroblastos humanos e testes sorológicos de Imunofluorescência Indireta (IFI-IgG/IgM) e Reação Imunoenzimática (ELISA-IgG). No momento da admissão no estudo 20% (10/50) dos pacientes apresentavam anticorpos IgM CMV específicos e 100% (50/50) deles anticorpos IgG (IFI). Durante o acompanhamento, 5 pacientes inicialmente IgM negativos tornaram-se IgM positivos, sugerindo reativação ou reinfecção pelo CMV. O CMV foi isolado de sangue periférico em 12,5%, da urina em 23,2%, da saliva em 21,9% dos pacientes. Exames anatomopatológicos foram realizados em 24 pacientes, correspondendo a 60% dos pacientes que evoluiram para óbito durante o período de estudo. Corpúsculos de inclusão citomegálica característicos foram observados em 50% das necrópsias, sendo o aparelho digestivo, pulmões e supra-renais os sítios mais acometidos. Não se observou uma relação estatisticamente significante entre os achados clínicos e os achados virológicos e anatomopatológicos.

The structure and nature of the crust underlying the Santos Basin-São Paulo Plateau System (SSPS), in the SE Brazilian margin, are discussed based on five wide-angle seismic profiles acquired during the Santos Basin (SanBa) experiment in 2011. Velocity models allow us to precisely divide the SSPS in six domains from unthinned continental crust (Domain CC) to normal oceanic crust (Domain OC). A seventh domain (Domain D), a triangular shape region in the SE of the SSPS, is discussed by Klingelhoefer et al. (2014). Beneath the continental shelf, a similar to 100km wide necking zone (Domain N) is imaged where the continental crust thins abruptly from similar to 40km to less than 15km. Toward the ocean, most of the SSPS (Domains A and C) shows velocity ranges, velocity gradients, and a Moho interface characteristic of the thinned continental crust. The central domain (Domain B) has, however, a very heterogeneous structure. While its southwestern part still exhibits extremely thinned (7km) continental crust, its northeastern part depicts a 2-4km thick upper layer (6.0-6.5km/s) overlying an anomalous velocity layer (7.0-7.8km/s) and no evidence of a Moho interface. This structure is interpreted as atypical oceanic crust, exhumed lower crust, or upper continental crust intruded by mafic material, overlying either altered mantle in the first two cases or intruded lower continental crust in the last case. The deep structure and v-shaped segmentation of the SSPS confirm that an initial episode of rifting occurred there obliquely to the general opening direction of the South Atlantic Central Segment.

CO2 capture from gaseous effluents is one of the great challenges faced by chemical and environmental engineers, as the increase in CO2 levels in the Earth atmosphere might be responsible for dramatic climate changes. From the existing capture technologies, the only proven and mature technology is chemical absorption using aqueous amine solutions. However, bearing in mind that this process is somewhat expensive, it is important to choose the most efficient and, at the same time, the least expensive solvents. For this purpose, a pilot test facility was assembled and includes an absorption column, as well as a stripping column, a heat exchanger between the two columns, a reboiler for the stripping column, pumping systems, surge tanks and all necessary instrumentation and control systems. Some different aquous amine solutions were tested on this facility and it was found that, from a set of six tested amines, diethanol amine is the one that turned out to be the most economical choice, as it showed a higher CO2 loading capacity (0.982 mol of CO2 per mol of amine) and the lowest price per litre (25.70 ¤/L), even when compared with monoethanolamine, the benchmark solvent, exhibiting a price per litre of 30.50 ¤/L.

A new family of eight ruthenium(II)-cyclopentadienyl bipyridine derivatives, bearing nitrogen, sulfur, phosphorous and carbonyl sigma bonded coligands, has been synthesized. Compounds bearing nitrogen bonded coligands were found to be unstable in aqueous solution, while the others presented appropriate stabilities for the biologic assays and pursued for determination of IC50 values in ovarian (A2780) and breast (MCF7 and MDAMB231) human cancer cell lines. These studies were also carried out for the [5: HSA] and [6: HSA] adducts (HSA = human serum albumin) and a better performance was found for the first case. Spectroscopic, electrochemical studies by cyclic voltammetry and density functional theory calculations allowed us to get some understanding on the electronic flow directions within the molecules and to find a possible clue concerning the structural features of coligands that can activate bipyridyl ligands toward an increased cytotoxic effect. X-ray structure analysis of compound [Ru(eta(5)-C5H5)(bipy)(PPh3)][PF6] (7; bipy = bipyridine) showed crystallization on C2/c space group with two enantiomers of the [Ru(eta(5)-C5H5)(bipy)(PPh3)](+) cation complex in the racemic crystal packing.
