Performance of UASB reactors in two stages followed by post-treatment with activated sludge in wastewater batch of wet-processed coffee

In this study it was evaluated the efficiency of the treatment of wet-processed coffee wastewater in upflow anaerobic sludge blanket (UASB) reactors in two stages, in bench scale, followed by post-treatment with activated sludge in batch. The first UASB reactor was submitted to an hydraulic retention time (HRT) of 6.2 d and organic loading rates (OLR) of 2.3 and 4.5g CODtotal (L d)-1, and the second UASB reactor to HRT of 3.1 d with OLR of 0.4 and 1.4g CODtotal (L d)-1. The average values of the affluent CODtotal increased from 13,891 to 27,926mg L-1 and the average efficiencies of removal of the CODtotal decreased from 95 to 91%, respectively, in the UASB reactors in two stages. The volumetric methane production increased from 0.274 to 0.323L CH4 (L reactor d)-1 with increment in the OLR. The average concentrations of total phenols in the affluent were of 48 and 163mg L-1, and the removal efficiencies in the UASB reactors in two stages of 92 and 90%, respectively, and increased to 97% with post-treatment. The average values of the removal efficiencies of total nitrogen and phosphorus were of 57 to 80% and 44 to 60%, respectively, in the UASB reactors in two stages and increased to 91 and 84% with the post-treatment.

Análise faciológica e estratigráfica das formações Taciba (parte superior) e Rio Bonito (membro Triunfo) em poços testemunhados da área de Monte Alegre (PR)

The Triunfo Member, from Rio Bonito Formation, is a potential reservoir for hydrocarbons and water, and contains coal deposits in the northern state of Paraná. On the eastern edge of the Paraná Basin, the Triunfo Member has two depocenters in Santa Catarina and offlap to the North of Paraná; here in two adjacent areas characterized his final lapout. These areas have a number of wells core/logged with the initials MA and NF, Monte Alegre and Figueira North, which were drilled by the Companhia de Pesquisa e Recursos Minerais (CPRM), in order to research for coal in the Rio Bonito Formation. In this study, three wells in the MA area, and they were MA-4, MA-6 and MA-7 was subjected to vertical facies analysis (1D), from the description of wells and processing of data, so that later it was possible to chronocorrelate thereof, together with MA-5 well, through cycles facies (2D). This is a thesis which has never been developed in these wells mentioned above, it was possible to observe the development of part of the Member Taciba (top) and the Member Triunfo as a whole, can be determined three cycles facies to the latter, as well as their depositional environments. Finally, the chronocorrelate showed that there is a tabular architecture between the wells studied, this occurred because of subsidence uniform

Estudo e modelagem 3D de uma turbina Francis

Most of the hydraulic turbines that are running in the world are the Francis type, because they are able to fit a wide range of head and flow. We also can declare that most of the installed hydraulic energy up to this date is generated by this type of turbine. On the other hand, if we pay attention to mechanical details of a Francis turbine we will see that among the three most used types it is the one that presents the more complex design. And, the simplest one is the Pelton type, whereas the Kaplan is the one less utilized. This work aims to develop the hydrodynamic calculation of a Francis turbine as well as to obtain its assembly drawing and 3D modeling drawing. In this way all details must be shown therefore needing a complete knowledge about this issue. Both 2D and 3D drawings help much if one wants the machine to be running in its power house. It is well noted that most of the entities that design and manufacture the Francis turbines are not brazilian. In this way the more we study how to design this kind of machine the more is our contribution to our country in order to conquer technology and manufacture Francis turbines

Asymmetric and Symmetric Triazenido Cyclopalladated Complexes: Synthesis, Structural Analysis and DFT Calculations

The reaction of [Pd{dmba}(l-N3)]2 (dmba = N,N-dimethylbenzylamine) with 1-(2-fluorophenyl)-3-(4- nitrophenyl)triazenido (L1 ) or 1,3-bis(4-nitrophenyl)triazenido (L2 ) anions, in methanol, and subsequent treatment with pyridine (py) allows the preparation of the corresponding cyclopalladated compounds [Pd(dmba)(L1 )(py)] (1) and [Pd(dmba)(L2 )(py)]py (2). The acentric mononuclear entities of (1) and (2) are connected by weak intermolecular non-classical CAHC hydrogen bonds, which results in 2-D arrangements by translation, along the [1 0 0] and [0 01] crystallographic directions, respectively.

Computer graphics applied to anatomy: a study of two bio-cad modeling methods on finite element analysis of human edentulous hemi-mandible

Modeling is a step to perform a finite element analysis. Different methods of model construction are reported in literature, as the Bio-CAD modeling. The purpose of this study was to perform a model evaluation and application using two methods of Bio-CAD modeling from human edentulous hemi-mandible on the finite element analysis. From CT scans of dried human skull was reconstructed a stereolithographic model. Two methods of modeling were performed: STL conversion approach (Model 1) associated to STL simplification and reverse engineering approach (Model 2). For finite element analysis was used the action of lateral pterygoid muscle as loading condition to assess total displacement (D), equivalent von-Mises stress (VM) and maximum principal stress (MP). Two models presented differences on the geometry regarding surface number (1834 (model 1); 282 (model 2)). Were observed differences in finite element mesh regarding element number (30428 nodes/16683 elements (model 1); 15801 nodes/8410 elements (model 2). D, VM and MP stress areas presented similar distribution in two models. The values were different regarding maximum and minimum values of D (ranging 0-0.511 mm (model 1) and 0-0.544 mm (model 2), VM stress (6.36E-04-11.4 MPa (model 1) and 2.15E-04-14.7 MPa (model 2) and MP stress (-1.43-9.14 MPa (model 1) and -1.2-11.6 MPa (model 2). From two methods of Bio-CAD modeling, the reverse engineering presented better anatomical representation compared to the STL conversion approach. The models presented differences in the finite element mesh, total displacement and stress distribution.

Impact of biannual rossby waves on the Indian Ocean Dipole

Topex/Poseidon sea surface height anomalies during 1993-2002 are decomposed using 2-D finite impulse response filters which showed biannual Rossby waves (BRWs) in the equatorial Indian Ocean (peak at 1.5 degrees S) and in the southern tropical Indian Ocean (peak at 10.5 degrees S) during Indian Ocean Dipole (IOD) years. Anomalous downwelling BRWs in the equatorial Indian Ocean triggered by the wind stress curl-induced Ekman pumping near the eastern boundary started propagating westward from the eastern boundary in July/August 1993 and 1996, i.e., more than one year prior to the formation of the IOD events of 1994 and 1997 respectively. These strong downwelling signals reach the western equatorial Indian Ocean during the peak dipole time.
