Este trabalho descreve a correlação entre parâmetros de uso da terra (área agricultada, área edificada, pastagem, solo exposto e vegetação intermediária) e de qualidade da água subterrânea (pH, sólidos totais dissolvidos - STD, K+, Na+, Fe+3, Ca+2, Mg+2, NO2 -, NO3 -, P total e coliformes), no sul do estado do Espírito Santo. A delimitação da área de influência de poços e a identificação das classes de uso da terra foram feitas utilizando-se Sistema de Informações Geográficas. Por meio da análise de correlação canônica, foi possível estimar dois índices: índice de uso da terra e índice de qualidade da água, ambos padronizados. A correlação canônica foi significativa entre o primeiro par de variáveis canônicas, indicando relação linear entre os grupos. Desta forma, é possível afirmar que o uso da terra influenciou a qualidade da água subterrânea, principalmente pelo incremento da concentração de alguns elementos químicos.

In Brazil, common bean is in one of the most representative economic crops, not only because of its growing area but also because of the economic value of its production. In the crop year 2006/07, in Selvíria (MS), we analyzed the common bean yield as a function of some physical attributes of a Typic Acrustox in minimum tillage and center pivot irrigation system. The aim of this work was to evaluate among the soil physical attributes, under minimum tillage, those that better explain the variability of bean yield using the Pearson and spatial correlations,. A geostatistical grid was installed to collect data from soil and plants, with 117 sampling points in an area of 2025 m² and homogeneous slope of 0.055 m m-1. The results showed a low yield of bean, which occurred probably due to a lower density of plants that the system provided. Thus, for the minimum tillage system, the bean yield could be explained as a function of total porosity and bulk density.

Currently, anastomosis groups (AG) of Rhizoctonia sp. on chrysanthemum and occurrence of this fungus on gypsophila have not been reported in Brazil. However, in the present study, normal and cross pathogenicity and sequencing of ITS-5.8S rDNA regions were used to confirm the AG of isolate of Rhizoctonia sp. obtained from chrysanthemum (White Papyrus) and from gypsophila plants cultivated in Holambra / São Paulo, Brazil. After these tests, it was confirmed the report of Rhizoctonia solani AG-4 HG I on chrysanthemum (White and Yellow Papyrus) and R. solani AG-4 HG III on gypsophila in the São Paulo state, Brazil, and also their cross pathogenicity.

Anamnesis, clinical examinations and temporomandibular joint transcraneal radiographs for 22 adults with cleft lip and palate were carried out in order to evaluate the occlusion and correlate it with radographic findings. The conclusions were: 72.8% of the patients have at least one sign or symptom of craniomandibular disorders (CMD); although the occlusal conditions were severely altered, most of the signs and symptoms were classified as mild; the greater frequency of the signs and symptoms occurred among women; in the radiographic evaluation, all of the assymptomatic patients had both condyles with normal contour and all of the patients with altered contour had at least one sign or symptom; the bilateral centered position of the condyles in the fossa e did not warrant the absence of signs and symptoms; some patients with bilateral condyles positioned posteriorly or caudally or even assimetrically, did not present signs and symptoms of dysfunction; the radiographic findings should be correlated with clinical findings; and a great number of patients were not observed with clinical board of C:MD caused by the occlusion. Key words: Radiography; temporomandibular joint; temporomandibular joint syndrome; cleft palate; dental occlusion
