1. SPATIAL VARIABILITY OF THE SATURATED HYDRAULIC CONDUCTIVITY OF SOIL IN COCOA FARMING IN RECÔNCAVO BAIANO
RESUMO O cultivo de cacau irrigado abriu espaço para a produção em solos de Tabuleiros Costeiros. Porém, nesta região, a camada coesa formada próxima da superfície, pode ser um fator limitante para sua produção. O conhecimento dos atributos físico-hídricos do solo possibilitará um manejo eficiente da irrigação em solos coesos. Com isso, objetiv

2. Aplicação localizada de herbicidas.
ABSTRACT: Curent interest in site-specific weed control considering the weed spatial variability is increasing nowadays, when economical and environmental aspects are considered. This paper reviews the patch spraying methods for herbicides application systems regarding the economical and technical aspects. Using this new approach high herbicides savings are

3. QUALIDADE FÍSICA DE UM LATOSSOLO SOB PLANTIO DIRETO SUBMETIDO À ESCARIFICAÇÃO DE SÍTIO ESPECÍFICO E O RENDIMENTO DA SOJA / OXISOLS PHYSIC QUALITY AFYER SITE SPECIFIC CHISEL TILLAGE AND SOYBEAN YIELD UNDER NO-TILL
The soil compaction has been noted under no-till especially in clay soil texture. One important characteristic of soil compaction in cropland is non-uniform occurrence. With precision farming (PF) is possible determine spatially the soil compaction allowing the site specific management defined as site specific chisel (SSC). This work was carried out in a cro

4. Indicadores de sustentabilidade da produção familiar mecanizada de grãos em modalidades de plantio direto no Norte do Paraná, Brasil
Thirteen farms of the Network of References for Household Farming that use no-tillage tecnhnology in grain production were studied with regard to their economic revenues and classified according type and time of no-tillage adoption. Six of them were selected for detailed study of morphological, phisical and chemical atributes of their soils. The objective wa

6. Mapeamento da variabilidade espacial das plantas daninhas com a utilização de ferramentas da agricultura de precisão. / Mapping weed spatial variability using precision farming tools.
Traditionally the weed management has been done considering the overall weed infestation in the whole field and then herbicides are sprayed according to a single weed control recommendation for the field. But weeds are not uniformly distributed and normally have clumped populations showing weed patches presenting high spatial variability. This nature of the

7. Squamous cell skin cancer in the North-west of England, 1967-69, and its relation to occupation
ABSTRACT During the three years 1967-69, 781 cases of squamous cell carcinoma of the skin were reported to the Manchester Regional Cancer Registry. The proportions of males to females were significantly different (p <0·001) among the skin cancer sites. The age-specific incidence rates were significantly different (p <0·001) between the sexes for the five-y
