The protozoan parasite Giardia lamblia is responsible for a common intestinal infection in all regions of the world. In this study, four laboratory tests were evaluated for diagnostic reproducibility in the detection of this infection: Coprotest®, Direct modified method, Faust method and iron-hematoxylin staining. Positive diagnoses were tested for association with factors such as the age group and gender of the subject and the month when the sample was taken. Feces of 200 children in the Araraquara region (SP, Brazil) were examined by all four methods and the results compared. G. lamblia was found to be the most frequent parasite and 8.0% of the children showed giardiasis. There was no apparent correlation with gender, but most of the parasites were found in three- to five-year-olds. The highest frequency of infection occurred in January. The most reliable diagnostic results for G. lamblia were achieved by combining at least two methods of good reproducibility, i.e. Coprotest-Faust, Direct-Faust or Coprotest-Direct (A > 0.81).

The objective of this work was to analyze the consumption, electric energy cost, and economic results of irrigated citrus (Citrus sinensis). The treatments consisted of a dripping irrigation system with one and two lateral distribution lines, a micro sprinkler irrigation system and a treatment without irrigation. For each irrigation system, three water depths were used: 100%, 75% and 50% of Etc (citrus evapotranspiration). The electric energy cost for two tariff groups, Group A and Group B, was studied. For Group A, the expenses with energy were determined for the Conventional Binomial Structure tariff, the Hour-seasonal tariff (green and blue) and the special tariff for nocturnal irrigation. The kWh cost for the tariff systems were obtained from the website of CPFL (São Paulo State Power and Light Company, Brazil). The best relation between the electric energy consumption (kWh.ha -1) and productivity (t.ha -1) occurred in the treatment irrigated with 50% of the Etc. The irrigated treatments increased productivity. The biggest productivity was observed in the irrigation treatments with 50% of the Etc when compared to the ones with 100% of the Etc. The blue and green Hour-seasonal tariff system of Group A (nocturnal irrigation) was the best option. A biggest economic turnover occurred in the treatments irrigated with 50% of the Etc.
