High temperature superconducting demonstrator transformer: design considerations and first test results
No full textThe University of Southampton has designed a 10 kVA single-phase high temperature superconducting (HTS) demonstrator transformer. This article highlights the main features of this transformer, particularly the cooling system.</p
Optimization of signal-to-noise ratio in dc soundings
No full textGeoelectric (dc) sounding methods are usually limited to electrode spacings smaller than 1 km, which restrict the depth of investigation to only several hundreds of meters. Greater depths of investigation require both a larger electrode spacing and motor-generator driven transmitters. In order to increase the depth of investigation into the middle crust, the distance between transmitter and receiver dipole must be increased up to 100 km as well. Instead of a Schlumberger electrode configuration, we use a dipole-dipole electrode arrangement, which avoids cable connections of several tens of kilometers. It takes less logistics in the field and requires less precautions to control the cable circuits. However, the electric field of a grounded dipole decays by the power of 3. Even if a strong current source with a power of 30 kW is employed, at distances beyond 10 km the amplitude of the transmitted de signal becomes considerably smaller than the naturally inductive held and cultural noise. Here, we present a technique which resolves the transmitted de signal at sites up to 60 km apart using an electric dipole source. The suggested technique removes the inductive part in the time series and, therefore, reduces the noise level. It requires applying the magnetotelluric technique before and/or after the geoelectrical sounding. Both the magnetic and electric variational fields are recorded during geoelectrical sounding. If the magnetotelluric transfer function is obtained at a site, then the natural inductive electric field can be predicted, which in turn is used to remove the inductive electrical part from the receiver dipole record

Estudo comparativo entre os métodos de Stoll e Kato quantitativo
No full textA autora realizou a contagem de ovos por gr. de fezes em 129 amostras de fezes pelos métodos de Kato e de Stoll, incluindo 100 casos de parasitismo por Ascaris lumbricoides, 100 por Trichuris trichiura, 70 por ancilostomideos e 40 por S. mansoni. Os resultados foram avaliados estatisticamente, evidenciando-se idênticos com as duas técnicas no que se refere a Ascaris lumbricoides, T. trichiuris e S. mansoni, mostrando-se, no entanto, o método de Stoll mais adequado para a contagem de ovos de ancilostomideos.The author examined 129 specimens of faeces using the techniques of Kato and Stoll. 100 cases of Ascaris lumbricoides infection, 100 of Trichocephalus trichiurus, 70 of hookworm infection and 40 of Schistosoma mansoni were detected. The number of eggs eliminated per gram of faeces was determined using the two methods. The results were statistically analysed using the comparative tests for the two methods at a significance levei of 0,05. The results showed that, for counting eggs, the two techniques presented equal results for A lumbricoides, T. trichiurus and Schistosoma mansoni, but the Stoll technique was more sensitive for hookworm
