Pinheiro, Zuleika Bezerra;Rodrigues, Kelly;Pessoa-Wanderley, Carlos Ronald;Araújo, Rinaldo dos Santos;Marinho, Glória;
Engenharia Sanitaria e Ambiental , 2010, DOI: 10.1590/S1413-41522010000100006
Abstract: in this work, an aqueous mean containing 250 mg/l of phenol and macro and micro nutrients was submitted to treatment in a continuous fixed bed reactor inoculated with the aspergillus niger. the reactor was operated under eight hours of hydraulic detention, divided into two feeding phases in the presence (phase i) and absence (phase ii) of 0.5 g/l of glucose in the mean. the organic matter removal, measured in chemical demand of oxygen and phenol were of 92% and 99% in phase i, and 77% of organic matter and phenol in phase ii. the loss of the efficiency observed in the phase ii was attributed to extreme production of biomass and mucilage inside the reactor and for the reduction of the enzymatic activity of the involved microorganisms in the process.

Abstract: the objective of this investigation was to evaluate the in vitro sensibility of staphylococcus spp. to several commercially available disinfectants used for pre and post dipping. a total of 60 isolates of staphylococcus spp., identified as staphylococcus aureus (50) and positive coagulase staphylococcus (10) were obtained from the mammary glands of dairy cows with subclinical mastitis in the regions of metropolitan recife, the agreste and the zona da mata of the state of pernambuco, brazil. as active ingredients were used a chlorine base (25%), iodine (0.6%), chlorhexidine (2.0%), quaternary ammonium (4.0%), and lactic acid (2.0%) at four specific intervals (15", 30", 60", and 300"). one hundred percent of s. aureus was found to be sensitive to iodine, 93.3% to chlorhexidine, 80% to ammonia, 35.6% to lactic acid, and 97.8% were resistant to chlorine at a 60-minute interval. with respect to the positive coagulase staphylococcus (scp), 100.0% of the isolates were sensitive to iodine, 81.8% to quaternary ammonium, 99.9% to lactic acid, 72.7% to chlorhexidine, and 100% was resistant to chlorine at an interval of 60 minutes. it can be concluded that the highest disinfectant activity in vitro was found to be with iodine and chlorhexidine for s. aureus, and with iodine and lactic acid for scp. a further conclusion was that it is important to undertake a periodic evaluation of the disinfectants used on the dairy properties in the regions studied, given the variety of sensibilities and resistance to disinfectants used, which may prejudice the control of bovine mastitis caused by staphylococcus spp.
Velhas teses, novos dados: uma análise metodológica
Santos, Wanderley Guilherme dos;
Dados , 2004, DOI: 10.1590/S0011-52582004000400004
Abstract: the author revisits the themes proposed by jairo nicolau in a previous article (dados, vol. 47, no 1, 2004) concerning coalition votes in brazil. using election tables from the superior electoral court and tables amended by nicolau, the author evaluates whether the data studied by nicolau support the thesis that he significantly modified the original electoral court data and thereby invalidated current hypotheses on variations in party votes from 1946 to 1962 in relation to the degree of nationalization in the brazilian party system and fractionation rates, both during the same period. the author concludes that nicolau's theses are invalid, including the use he makes of the concept of "effective number of parties".
Poliarquia em 3D
Santos, Wanderley Guilherme dos;
Dados , 1998, DOI: 10.1590/S0011-52581998000200001
Abstract: the article takes issue with positions that reduce representative systems to democratic linearity, considering how the latter is restricted to variations in forms of government and electoral systems that do not correspond to the growing complexity of national organizations. it is proposed that a third dimension be added to robert dahl?s bidimensional model that is, eligibility from which it is possible to derive minimalist yet strict definitions of authoritarian systems, of representative systems in general, and of their oligarchical and polyarchical variations.
A anomalia democrática: adolescência e romantismo na história política
Santos, Wanderley Guilherme dos;
Revista Brasileira de Ciências Sociais , 1998, DOI: 10.1590/S0102-69091998000100001
Abstract: democratic suffrage with minimal age requirement organizations are recent phenomena in political history, even if we consider its minimalist definition: regular elections with the warranty of respect to the results, and universal suffrage with minimal age requirement. having its origin in a spatial conception of individual worth, the contemporary democratic systems not only have not solved but also try to conceal a fundamental problem: the irredentists' autonomy. the democratic power is also a constant threaten to liberty.

Abstract: Organiza es políticas democráticas s o fen menos recentes na história política, mesmo se observarmos sua defini o minimalista: elei es regulares com garantia de respeito aos resultados e direito de voto universal, com requisito mínimo de idade. Tendo por origem concep o especial do valor do indivíduo, os sistemas democráticos contemporaneos n o só ainda n o resolveram, como procuram ocultar um problema fundamental: a autonomia dos irredentos. O poder democrático também é amea a constante à liberdade.

Tratamento de água com hidrocarbonetos aromáticos por uso de reator em bateladas sequenciais com inoculo fúngico

Abstract: a batch reactor with air and immobilized biomass of aspergillus niger an400 was operated during 10 cycles of 7 days to remove benzene (200 mg.l-1), toluene (200 mg.l-1), and xylene (50 mg.l-1) - btx - and nutrients from basal medium. the reactor was weekly fed with 4 l of the medium and glucose - 1 g.l-1 (phase i) and 0.5 g.l-1 (phase ii). the btx had been detected until the fourth day of operation in all cycles. the best efficiencies of removal had been in phase i: 75% of soluble organic matter, 80% of orthophosphate and 77% of ammonia. the reactor can be a viable alternative for the contaminated water treatment with btx. however it has the necessity to study behavior of the reactor during longer period of operation and with shorter reaction cycles, as well as the identification of the produced metabolites.

Abstract: palynological studies reveal a wide variation in shape, number and types of apertures in passiflora pollen grains. this study aimed to characterize pollen grain apertures of eleven species of passiflora from rio grande do sul state and two species from santa catarina state (brazil), belonging to three of the four subgenera now recognized: astrophea, decaloba and passiflora. several techniques of light and scanning electron microscopy were employed. passiflora haematostigma (astrophea) has 6-colporate pollen grains with three lalongate endoapertures. passiflora alata, p. amethystina, p. caerulea and p. edulis (passiflora) have 6-colpate pollen grains, with fusion of ectoapertures pairs in the apocolpium. passiflora actinia, p. elegans and p. tenuifila (passiflora) have pollen grains with 6 to 12 colpi, also fused in pairs. passiflora misera, p. morifolia, p. suberosa and p. truncata (decaloba) have 6-colporate operculate pollen grains, with differences in endoaperture size and operculum width. passiflora capsularis (decaloba) has 12-colporate pollen. the main palynological terms and synonyms in the literature are discussed.
