Uso de traçador salino para avaliação da colmatação e das condições hidrodinâmicas em sistemas alagados construídos de escoamento horizontal subsuperficial

Autor: Mateus P. Matos, Marcos V. Sperling, Antonio T. Matos, Ricardo G. Passos

Publikováno v: Engenharia Agrícola, Vol 35, Iss 6, Pp 1137-1148 (2015)

RESUMO A colmatação é um fenômeno intrínseco aos sistemas alagados construídos (SACs) utilizados no tratamento de esgotos, sendo decorrente dos mecanismos de remoção de poluentes. Dentre os métodos disponíveis para a avaliação da colmata�

Avaliação de desempenho de reator UASB no tratamento de águas residuárias de suinocultura Evaluation of performance of UASB reactor in swine wastewater treatment

Autor: Luciano S. Rodrigues, Israel J. da Silva, Manon C. de O. Zocrato, Débora N. Papa, Marcos V. Sperling, Paulo R. de Oliveira

Publikováno v: Revista Brasileira de Engenharia Agrícola e Ambiental-Agriambi, Vol 14, Iss 1, Pp 94-100 (2010)

Este trabalho apresenta o desenvolvimento e a avaliação de um sistema de tratamento de águas residuárias de suinocultura constituído de decantador e seguido de reator anaeróbio de manta de lodo (reator UASB), em escala real. O reator UASB foi c

Structured sparse matrix-vector multiplication on massively parallel SIMD architectures

Autor: V. Sperling, T. Dehn, K. Giebermann, Michael Eiermann

Publikováno v: Parallel Computing. 21:1867-1894

We propose an algorithm for the cost-effective evaluation of structured sparse matrix-vector multiplications on massively parallel SIMD computers with distributed memory. Under the assumption that a large percentage of the nonzero entries of the matr

Electric field induced absorption modulation of CdS quantum dots in an organic matrix

Autor: O. Wind, V. Sperling, Ulrike Woggon, S.V. Bogdanov

Publikováno v: Journal of Crystal Growth. 138:976-980

CdS quantum dots under weak confinement conditions embedded in a polyvinyl alcohol (PVA) polymer film have been studied in the presence of an external electrical field at different densities of photoexcited carriers. Applying an external electric fie

Determination of the Settling Velocity of Phosphorus in an Aerated Lake

Autor: E. V. Sperling

Publikováno v: Water Science and Technology. 26:1973-1979

The paper deals with the determination of the settling velocity of phosphorus in lakes and reservoirs. The main approaches to estimate the phosphorus loss in aquatic ecosystems are presented. A case study of a lake situated in Berlin, Germany is disc

Coexistence of dot and wire-like structures of CdS embedded in a polymer

Autor: A. Lohde, Ulrike Woggon, V. Sperling, Thomas Haalboom

Publikováno v: Journal of Luminescence. :395-397

We have studied the linear absorption and the photoluminescence of quantum-confined structures in a polyvinylalcohol matrix doped with CdS. We could observe a coexistence between rather spherical and rod-like growth phases. The different stages of th

Klebsiella typing: pulsed-field gel electrophoresis (PFGE) in comparison with O:K-serotyping

Autor: V. Sperling, Dennis S. Hansen, Robert Skov, J.V. Benedí, Hans Jørn Kolmos

Publikováno v: Clinical microbiology and infection : the official publication of the European Society of Clinical Microbiology and Infectious Diseases. 8(7)

Objective To compare pulsed-field gel electrophoresis (PFGE) typing and O:K-serotyping of Klebsiella in two different epidemiological settings. Methods One hundred and four bacteremia isolates without known epidemiological relation and 47 isolates fr
