Comportamento espacial da cultura canavieira no Estado de Sao Paulo, 1980

Data from the agricultural and Cattle Raising Census for 1980 show that most of the sugar cane producing counties lie in the administrative regions of Campinas, Ribeirao Preto and Sao Jose do Rio Preto. A comparison with the 1975 data shows two important facts; 1) an increase of the cultivated area in 118 counties and 2) an increase in the number of counties with area under sugar cane. There was also an expansion in the sub-regions of Catanduva, Assis and Ourinhos. Nevertheless, Piracicaba, Araraquara, Ribeirao Preto, Jaboticabal and Jau, have continued to be important sugar cane producing nuclei in the State since 1960. -from English summary

Fuzzy sets in distributed traffic control

The task of controlling urban traffic requires flexibility, adaptability and handling uncertain information spread through the intersection network. The use of fuzzy sets concepts convey these characteristics to improve system performance. This paper reviews a distributed traffic control system built upon a fuzzy distributed architecture previously developed by the authors. The emphasis of the paper is on the application of the system to control part of Campinas downtown area. Simulation experiments considering several traffic scenarios were performed to verify the capabilities of the system in controlling a set of coupled intersections. The performance of the proposed system is compared with conventional traffic control strategies under the same scenarios. The results obtained show that the distributed traffic control system outperforms conventional systems as far as average queues, average delay and maximum delay measures are concerned.

Ascomycetous Yeasts Associated with Naturally Occurring Fruits in a Tropical Rain Forest

Fruits from twenty different species of angiosperms were collected during the period from November, 1991 to January, 1992. Two hundred and two strains of yeasts and yeast-like fungi were isolated, of which 74 % showed ascomycetic affinity. Candida was the predominant genus, followed by (in descending order of occurrence): Cryptococcus, Klœckera, Sporobolomyces, Pichia, Hanseniaspora and Bullera. Black yeasts and other strains showing basidiomycetic affinity were also isolated. The genus Candida represented the highest number of identified species and the greatest variety of associated substrates. Among the ascomycetes and their anamorphs, 38 species were identified, with Klœckera apiculata being the most frequent among the isolates and the one which occurred in the largest variety of substrates. Some of the biotypes designated as Candida sp. A, B, C, D, E, F, G, H, I, and Pichia sp. did not correspond to the standard species description found in the literature, and may represent new species. The strains of yeasts isolated in this study were characterized and incorporated into the Tropical Culture Collection of the Fundação Tropical de Pesquisas e Tecnologia André Tosello, Campinas, São Paulo.

Phenological aspects of flowering and fruiting at the Ecological Station of Paulo de Faria-SP-Brazil

The present work was carried out at 'Estacao Ecologica de Paulo de Faria', north of the state of Sao Paulo, southeast of Brazil (19°55'-19°58'S and 49°31'-49°32'W). The flowering and fruiting phenology of trees, shrubs, and lianas species were observed from April 1993 to December 1995. The results were compaired with those surveyed at other forests from Sao Paulo state: Santa Genebra (Campinas). Serra do Japi (Jundiai) and lianas of Mata Atlantica. The majority of species of lianas flowered from January to April and trees and shrubs between September to December. The most intense frutification period occurred during May to August. Similarly to Santa Genebra, the flowering season at 'Estacao Ecologica de Paulo de Faria' started at the beginning of the wet season while frutification during the dryest period of the year. At Serra do Japi, the flowering and frutification occurred from the end of dry and beginning of the rainy season. Considering the liana at Mata Atlantica presented two peaks of flowering, while at 'Estacao Ecologica de Paulo de Faria' occurs only one. Regarding the fruiting phenology is similar for both area, most species producing fruits during the first semestre.

Escalated aggressive behaviour and facultative parental care in the nest building gladiator frog, Hyla faber

Agonistic encounters and facultative parental care in Hyla faber were observed in two localities in southeastern Brazil. Maximum male density was 0.9 and 3.3 males/m2 in Campinas and Ribeirão Branco, respectively. Aggression was escalated and the highly variable aggressive calls were specific to each phase of the encounter. The last, more aggressive phases rarely occurred in Campinas; in Ribeirão Branco they occurred frequently. Male parental care (egg attendance) was common in Ribeirão Branco while it was never observed in Campinas. Egg attendance lasted one to two nights and was observed only during high male density. The main benefit of egg attendance seemed to be avoiding nest intrusion by other males (sunken eggs and/or embryos invariably die). Males may build additional nests during egg attendance, but attending males did not attract females (they did not call).

Capacidade combinatória para frutificação em cultivares de nogueira macadâmia

A 5 × 5 diallel experiment was conducted at Experimental Station of Tietê, SP, aiming to evaluate the combining ability amongst macadamia nut trees (Macadamia integrifolia Maiden & Betche) cultivars IAC Campinas A, IAC 2-23 A, IAC 4-12 B, IAC 4-20 e IAC 5-10. The initial fruit set was evaluated 14 days after manual pollination and showed that every cultivar presented self incompatibility. There were significant general and specific combining ability amongst cultivars and reciprocal effects. The cultivar IAC Campinas A reduced the initial fruit set at all crossing in which was used as female progenitor. The best results for initial fruit set were showed by crossings between following cultivars: IAC 4-20 × IAC Campinas A, IAC 4-12 B × IAC 2-23 A, IAC 4-20 x× IAC 4-12 B, IAC 5-10 × IAC 2-23 A, IAC 5-10 × IAC 4-20, IAC 4-20 × IAC 2-23 A e IAC 5-10 × IAC 4-12 B.

Desiccation tolerance of four seedlots from Euterpe edulis Mart.

In order to identify the desiccation tolerance of E. edulis seeds, four fruitlots were collected from the Campinas Agronomic Institute Palmae collection, located at Ubatuba, state of Sao Paulo, Brazil, and taken in moisture-proof containers to the College of Agriculture in Botucatu, state of Sao Paulo. There, the fruits were shelled and the seeds were dried, either under silica gel conditions or in a drying chamber. The effects of dehydration were evaluated by measurements of the germination, embryo protrusion, germinative button, plumule, speed of emergence, seedling length, seed dry matter and water content. Differences among seedlots and between harvest season for most of the traits were observed. Euterpe edulis seedlots seem to tolerate water content reductions until 39% without significant reduction in germination and vigor. Below this value, most of the evaluated traits were negatively affected. Total loss of germination was observed whenever seed water content was reduced to values below 21%.

Carotenoid composition of hydroponic leafy vegetables

Because hydroponic production of vegetables is becoming more common, the carotenoid composition of hydroponic leafy vegetables commercialized in Campinas, Brazil, was determined. All samples were collected and analyzed in winter. Lactucaxanthin was quantified for the first time and was found to have concentrations similar to that of neoxanthin in the four types of lettuce analyzed. Lutein predominated in cress, chicory, and roquette (75.4 ± 10.2, 57.0 ± 10.3, and 52.2 ± 12.6 μg/g, respectively). In the lactucaxanthin-containing lettuces, β-carotene and lutein were the principal carotenoids (ranging from 9.9 ± 1.5 to 24.6 ± 3.1 μg/g and from 10.2 ± 1.0 to 22.9 ± 2.6 μg/g, respectively). Comparison of hydroponic and field-produced curly lettuce, taken from neighboring farms, showed that the hydroponic lettuce had significantly lower lutein, β-carotene, violaxanthin, and neoxanthin contents than the conventionally produced lettuce. Because the hydroponic farm had a polyethylene covering, less exposure to sunlight and lower temperatures may have decreased carotenogenesis.

Attentional disorders in patients with complex partial epilepsy

A study of concentrated attention patterns in epileptic patients was conducted with the objectives: characterization of the patients' epileptic condition; assessment of the concentrated attention levels in epileptic and nonepileptic individuals; comparison of the attention levels of the two groups. An evaluation was performed of 50 adult outpatients with complex partial seizures and 20 non-epileptic individuals (comparative group) at the Neuroepilepsy Ambulatory Unit, State University of Campinas SP, Brazil. Method: characterization of seizure types, frequency and duration; concentrated attention assessment (Concentrated Attention Test - Toulouse-Piéron); comparison of the epileptic with non-epileptic individuals. Results: A statistically significant difference was observed between the groups with regard to Correct Response, Wrong Response and No Response. A difference was observed in relation to Time, but it was statistically insignificant. The epileptic patients presented inferior cognitive performance in relation to concentrated attention when compared with the non-epileptic individuals, findings compatible with the clinical complaints.

Estrutura genética de populações de Trichilia pallida Swartz (Meliaceae) por marcadores RAPD

Trichilia pallida Swartz is an Atlantic Forest shady climax tree of Meliaceae family that presents insecticide properties against chewing insects like as some family trees, making it interesting for forestry uses. Forty plants of Oito Pontas Farm population were collected in Bofete County, Santa Genebra Ecological Station in Campinas County, and Caetetus Ecological Station in Gélia County, all in the Sao Paulo State, Brazil. Leaf DNA analysis was used by RAPD method, that showed 10 highly polymorphic primers, with 72 dominant markers, used to estimate genetic diversity within and among populations. The polymorphism within populations varied from 90.3 to 97.2%, and the effective allele number varied from 1.46 ± 0.33 to 1.57 ± 0.33, while the average of genetic differentiation of populations varied from 0.27 ± 0.18 to 0, 33 ± 0.15. The gene diversity in the total population (H T) was 0.334 ± 0.02, while the average gene diversity within populations (H s) was 0.292 ± 0.017, and the coefficient of gene differentiation (G ST) was 0.125, Bofete and Campinas populations had the smallest Nei's genetic distance (0.049) and the distances of both with Gália were 0.117 and 0.107, respectively.

Genetic variation in growth traits and yield of rubber trees (Hevea brasiliensis) growing in the Brazilian state of São Paulo

Analysis of variance and covariance was preformed on growth traits (stem girth, bark thickness, total height gain and rubber yield) of 22 open-pollinated progenies of the rubber tree Hevea brasiliensis from an Asian Hevea collection introduced to Agronomic Institute (Instituto Agronômico, Campinas, São Paulo, Brazil; IAC) in 1952. This progeny trial was replicated at three sites in São Paulo state and it was found that at three years from sowing there was statistically significant variation for girth, bark thickness, height and rubber yield. An individual test sites, values of individual plant heritability for girth ranged from ĥ i 2 = 0.36 to ĥ i 2 = 0.89 whereas values for heritability for progeny means ranged from ĥ i 2 = 0.77 to ĥ i 2 = 0.87. These moderate and high heritabilities suggest that a combination of progeny and within-progeny selection would be effective at increasing girth in this population at individual sites. Across sites, values of individual-plant heritability for girth ranged from ĥ i 2 = 0.36 to ĥ i 2 = 0.47, whereas values for heritability of progeny means girth ranged from ĥ x̄ 2 = 0.77 to ĥ x̄ 2 = 0.87. There were high positive genetic correlations between increased girth and bark thickness suggesting that breeding aimed at increasing girth would also increase bark thickness and possibly height.

As rochas intrusivas da Formação Serra Geral na Porção leste da Bacia do Paraná no Estado de São Paulo: Aspectos petrográficos e geoquímicos - Resultados preliminares

The purpose of this paper is to present preliminary aspects of the petrography and chemistry of intrusive rocks (sills and dykes) from the eastern portion of the Parana Basin in the State of Säo Paulo. Data from 80 samples of the region show a subaphyric and subophitic nature and have plagioclase (25-50%), augite (3-39%), pigeonite (0-10%) and magnetite (4-20%) as an essential minerals. Apatite and quartz are present as accessory minerals. The geochemical data of intrusive rocks show a basic to intermediate composition (48% < SiO 2 < 56%) and a high Ti nature (TiO 2 > 2%). Based on the minor and trace composition of the intrusive rocks, two different magma types were recognized, named Paranapanema and Pitanga. The spatial distribution of these magma types is not alleatory in the studied region. The intrusive rocks of Pitanga magma type are displayed in the Campinas-Paulinia region, while the Paranapanema magma type cover a large region above that one, between Rio Claro and Cajuru. Furthermore, the chemical composition of the lava flows of the Serra Geral Formation, sampled in this work, reveals a magma of Urubici type. So, the intrusive rocks of the eastern portion of the of State Säo Paulo are not the extension of the lava flows, or they aren't a portions which don't reach the surface.

Fitoterapia no sistema de saúde pública (SUS) no Estado de São Paulo, Brasil

Phytotherapy is a form of familiar treatment throughout the world and recommended by the World Health Organisation to be used in all regions, especially in the poorer countries, to improve the state of health of their people. The aim of this study was to describe the use of herbal medicine as an alternative therapy in the public health system in Sao Paulo State. The fieldwork consisted in obtaining information, from all the Regional Health Authorities in the State, about which municipal health areas use this therapy and sending them a questionnaire requesting details about the application of phitotherapy: when the therapy had been adopted, which plants were used, whether the programme had been discontinued or not and if so, for what reason. The cities that use the phytotherapy are: Campinas; Canas; Guaratingueta; Herculandia; Piquete; Pindamonhangaba; Roseira e Sao Jose do Barreiro, Ribeirao Preto, Sao Lourenço da Serra, Cruzeiro e Dobrada. And the three plant more used are: Guaco (Mikania glomerate); Calendula (Calendula officinalis) e Babosa (Aloe vera) The lack of support has led some Authorities to discontinue their active in 08 programmes. Nevertheless, it is concluded that the efficacy and low cost of herbal treatments has engendered a growing interest among health professionals in placing proposals for implanting this therapy in 13 cities in the Municipal Health. Thus, there should be growing practical support for the establishment of such programmes in the future.
