Efeitos da cobertura do solo com filme de polietileno azul no consumo de água da cultura da alface cultivada em estufa

The covering of the soil is an agricultural practice that intends to control the harmful herbs, to reduce the losses of water by evaporation of the soil, and to facilitate the harvest and the commercialization, once the product is cleaner and healthier. However, when the soil is covered important microclimatic parameters are also altered, and consequently the germination of seeds, the growth of roots, the absorption of water and nutrients, the metabolic activity of the plants and the carbohydrates storage. The current trial intended to evaluate the effect of soil covering with blue colored film on consumptive water-use in a lettuce crop (Lactuca sativa, L.). The experiment was carried out in a plastic greenhouse in Araras - São Paulo State, Brazil from March 3rd, 2001 to May 5th, 2001. The consumptive water-use was measured through two weighing lysimeter installed inside the greenhouse. Crop spacing was 0.25 m x 0.25 m and the color of the film above soil was blue. Leaf area index (IAF), was measured six times (7; 14; 21; 28; 35; 40 days after transplant) and the water-use efficiency (EU) was measured at the end. The experimental design was subdivided portions with two treatments, bare soil and covered soil. The average consumptive water-use was 4.17 mm day-1 to the bare soil treatment and 3.11 mm day-1 to the covered soil treatment. The final leaf area index was 25.23 to the bare soil treatment and 24.39 to the covered soil treatment, and there was no statistical difference between then.

Protocolos de investigação de variáveis psicológicas na epilepsia infantil

Epilepsy is a common chronic condition in the childhood and its diagnosis reveals psychological, social and family difficulties, that seem to be related with beliefs and quality of parents-children interaction. The purpose of this paper is to schematize investigation strategies for the psychological variables: beliefs, impact of the disease, family relationship, identification of changes. Based upon collected reports of epileptic children's parents and upon surveyed aspects of the literature, psychological questionnaires were elaborated to identify important variables that affect the child's epilepsy life and his family. The use of more appropriate investigation procedures facilitates the psychological evaluation and ensures the collection of data.

Derivação ventriculoperitoneal com válvula no tratamento da hidrocefalia infantil

From December-1965 to November-1969, 95 hydrocephalic infants have been operated upon using ventriculoperitoneal shunt with valve (88 cases with a Spitz-Holter valve, 6 cases with a Hakim valve and one case with a Pudenz-Heyer valve). Up to the present time (December, 1970) a total of 54 children are alive with a compensated hydrocephalus and 9 patients died, being impossible to follow-up the 32 remaining cases. The use of the ventriculoperitoneal shunt has eliminated all cardiovascular-pulmonary complications and reduced the number for surgical revisions. Besides, infections involving the draining system are less severe and more easily controlled than those occurring in the ventriculoatrial shunts. After analysis of the surgical techniques as well as complications and results the following conclusions are stated: 1) the use of a valve in the ventriculoperitoneal shunt difficults the oclusion of the peritoneal end of the draining system; 2) good results can be expected without reoperations in about 42,35% of hydrocephalus cases treated by ventriculoperitoneal shunt with valve; 3) ventriculoperitoneal shunts with valve showed better results when compared to ventriculoatrial shunts. This statement is made comparing two groups of hydrocephalic infants submitted to surgery at the same Service and in the same conditions, with the same follow-up period; 4) the cases presented permit to state that at present time the ventriculoperitoneal shunt with valve is the most suitable surgical procedure for hydrocephalus.
