Abstract: the balance between agonist and antagonist muscles in the joints is of great relevance to clinical practice and to sports performance. information about these parameters amongst olympic and especially paralympic athletes is scarce. the purpose of this study was to present the results of the isokinetic evaluation (cybex 6000) of the brazilian team that participated in the sydney paralympic games. the flexor and extensor muscles of the knee were evaluated in 11 soccer players with cerebral palsy (age: 24.6 ± 4.8 years; weight: 67 ± 5.5 kg; height: 177.7 ± 3.8 cm) and in 12 basketball athletes with mental disability (age: 24.7 years; weight: 76.6 kg; height: 184.4 ± 10 cm); for the judo blind athletes (age: 29.8 ± 5.6 years; weight: 87 ± 21.6 kg; height: 171.5 ± 6.9 cm), the shoulder rotator muscles were tested. findings show that the soccer players have a normal hamstring: quadriceps strength ratio despite the muscle weakness imposed by cerebral palsy. for the judo athletes, the ratio between external and internal rotators of the shoulder was within the normal range. the results for peak torque in the basketball players were similar to those of non-athletic individuals without disabilities. the values are presented in the article in order to be used as reference for the professionals involved in the area of disabled sports.

Abstract: soil management systems modify the spatial distribution of soil physical properties. the objectives of this study were to verify the spatial dependency and co-relationship of some soil physical properties by data fitting to individual and cross-semivariograms in an oxisol (typic haplorthox) under no-till and conventional tillage, in campo mour?o, state of parana, brazil. in april 2004, 128 undisturbed soil samples were collected in a 3 x 5 m grid, in the middle of the 5-0.15 m layer. the following soil physical properties were measured: soil bulk density, macroporosity, microporosity, total soil porosity and soil water content at a tension of 100 hpa (field capacity). the spatial variability in the single semivariogram of these soil physical properties was higher and the range in no-tillage was smaller than in conventional tillage. on the other hand, the cross-semivariogram of soil bulk density and total porosity or field capacity indicated spatial co-relationships with lower spatial variability and higher ranges in no-tillage than conventionally tilled soils. the cross-semivariogram suggested that soil bulk density showed a spatial co-relationships with the other soil physical properties in both soil management systems studied.

Abstract: among the techniques for soil moisture evaluation, the use of time domain reflectometry (tdr) stands out, which consists of an indirect, non-destructive, fast and accurate method less dependent on environmental factors. however, works carried out after its applications suggest the influence of factors related to soils structural and mineralogical characteristics, which makes necessary the site calibration for the tdr proper functioning. the aim of this work was to study the influence of bulk density (ds) on the volumetric soil water content (θ), using the tdr technique in a dystroferric red ultisol. a model that expresses the relationship between the soil dielectric constant (ka) and θ was adjusted by multiple polynomial regression, with the incorporation of ds for the estimation of its coefficients. the results showed that in this soil, the calibration model should take into account the effect of ds, without which the quality of the moisture estimates from the dielectric constant measurements is compromised. the results also highlighted the high sensitivity of tdr to the variation of soil moisture, making it possible the accurate use of this technique in actions involving the monitoring of the variation in soil moisture. the results indicated the need for further studies on the use of tdr in tropical soils.

Arquivos de Neuro-Psiquiatria , 1999,
Abstract: O acometimento do sistema nervoso central pela tuberculose pode se manifestar de duas formas principais: tuberculose meníngea ou tuberculoma. Esta forma é uma condi o que vinha decrescendo progressivamente, mas que encontrou nos dias atuais condi es ideais para o seu desenvolvimento. O presente estudo discorre sobre três pacientes que desenvolveram expans o paradoxal de les es de tuberculose cerebral durante o uso de tuberculostáticos, o que demonstra ser importante o acompanhamento tomográfico de pacientes que apresentem sinais neurológicos no curso do tratamento para a tuberculose. Os dois primeiros pacientes apresentaram o acometimento neurológico associado a tuberculose pulmonar, enquanto no terceiro havia história de tuberculose meníngea prévia. A tomografia computadorizada foi o exame utilizado para o acompanhamento desses pacientes. O tratamento constou do uso de tuberculostáticos e corticóide.
