Tabular cusum control charts of chemical variables applied to the control of surface water quality
Provedor de dados: 70
Autores: Follador,Franciele A. C.; Boas,Márcio A. Vilas; Schoenhals,Marlise; Hermes,Eliane; Rech,Clovis.
The aim of this study was to evaluate the application possibility of tabular CUSUM control charts in the quality control of chemical variables in surface water. It was performed bibliographic and field research to collect water samples from 2003 to 2009, totaling 30 samples, some monthly and others semi-annual in order to observe the variables that regulate water quality. It was found that these charts may be applied to control the quality of river water; showing to be effective in the perception of changes during the process, especially for small samples (n=1) which there is no repetition as in this research. It was also concluded that the Mandurim River does not presents significant levels of pollution.

Provedor de dados: 70
Autores: Hermes,Eliane; Rocha,Dayane C. da; Orssatto,Fábio; Lucas,Juliana F.R.; Gomes,Simone D.; Sene,Luciane.
The aim of this study was to isolate microorganisms that produce lipase and to assess the efficiency of COD removal intreatment of cheese whey under different operating conditions. The microorganisms were isolated from cheese whey and a commercial product; it was selectedthreemicroorganisms that obtained the best response to the lipolytic activity test through the enzyme index. Then, the microorganisms were inoculated in sterilized cheese whey samples, for two pH values (6.2 and 7.0), incubated at 35 °C and 150 rpm in shaker and the lipolityc activity and the efficiency of COD removal were measured in two time periods (24 and 48h). After incubation, it was observed that the treatments showed a good removal efficiency of COD for the pre-treatment and the...

Effect of biofertilizer obtained by anaerobic digestion of cassava effluent on the development of crambe plants
Provedor de dados: 91
Autores: Neves,Andressa C.; Bergamini,Camila N.; Leonardo,Rafaela de O.; Gonçalves,Manoel P.; Zenatti,Dilcemara C.; Hermes,Eliane.
ABSTRACT This study aimed to evaluate the effect of applying increasing doses of biofertilizer obtained by the anaerobic digestion of cassava effluent on the development of crambe plants. The experiment was conducted in a protected environment at the Federal University of Paraná (UFPR), Palotina Sector, between April and August 2015. A completely randomized design was used, and five different treatments with the following doses were applied in five replicates: 0, 40, 80, 120, and 160 kg ha-1 of K2O. The following parameters related to plant development were evaluated: final height, stem diameter, number of branches, dry shoot and root biomass, mass of the grains, and oil content. The 160 kg K2O ha-1 dose was found to have the best influence on the plant...

Uniformity microsprinkler irrigation system using statistical quality control
Provedor de dados: 65

ABSTRACT: The objective of this study was to evaluate the use of statistical quality control tools in the analysis of the uniformity of a microsprinkler irrigation system. For the analysis of irrigation Christiansen uniformity coefficient (CUC) and the distribution uniformity coefficient (DU) were statistically analyzed by means of the Shewhart control charts and process capability index (Cp). For the experiment 25 tests were carried out with a single micro sprinkler and subsequently seven different spacing between micro sprinklers were simulated. Control charts contributed to the diagnosis of the treatments to be under control and with satisfactory uniformity outcomes. Increase in process capability index was directly proportional to the average of CUC...
