Planejamento agrícola e implantação de sistema de cultivo de cana-de-açúcar com auxílio de técnicas geoestatísticas

Sugarcane is one of the most important crops of the Brazilian agribusiness and this importance justifies the use of techniques that allow the implementation of cultivation systems capable of reducing the variability of soil characteristics and the establishment of efficient agricultural planning. The aim of the present work was the planning and implementation of cultivation systems for sugarcane using geostatistical techniques, in the Pereira Barreto region, SP. An area of 505 ha was mapped using the global positioning system (GPS) and a Digital Elevation Model was elaborated (MDE). Soil samples were collected for 0-0.25 m depth, in each 7 ha, for their chemical attributes and texture characterization. Data were analyzed by descriptive statistics and geostatistics. The determination of the spatial distribution of soil granulometric and chemical attributes allowed the allocation of the studied sugarcane varieties according to soil fertility and clay content. The kriging maps of soil granulometric and chemical attributes brought useful information to the establishment of production environments with different soil and crop managements. The identification of different environments by means of geostatistical techniques allowed the precise planning of the sugarcane cultivation, as well as the adequacy of fertilization practices and the allocation of suitable sugarcane varieties adapted to the conditions imposed by differences in the soil attributes.

Planejamento, síntese e avaliação farmacológica de compostos híbridos potencialmente ativos para o tratamento da anemia falciforme

Sickle cell disease (SCD) is a hereditary hemolytic anemia caused by the inheritance of one S hemoglobin gene from each ancestor. Patients with SCD present increased circulating levels of cytokines, including TNF-alpha (TNF-α). Hydroxyurea (HU) is the available therapeutically strategy for treatment; it acts as a source of nitric oxide and benefits patients by increasing the levels of fetal hemoglobin (HbF). Thus, within one research line that aims at finding new drugs, a series of compounds with TNF-α inhibition and nitric oxide donation properties have been synthesized in order to explore possible synergism of actions beneficial in the treatment of the disease. Six compounds were synthesized: five derivatives of organic nitrates and one of sulfonamide. The compounds, (1,3-dioxo-1,3-dihydro-2Hisoindol-2-yl) methyl nitrate (compound I); (1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) ethyl nitrate (compound II); 3-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound III);4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)-N-hydroxybenzenesulfonamide (compound IV); 4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) benzyl nitrate (compound V) and 2-[4-(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl) phenyl]ethyl nitrate (compound VI), were synthesized using linear synthetic methodology, with excellent overall yields. All compounds showed anti-inflammatory and analgesic effects with a reduction in 43%-65% of ear edema in mice and a reduction of 25%-42% of writhing induced by acetic acid. All compounds showed comparable reductions in the leukocyte infiltration capacity and ability to generate nitric oxide. The aryl compounds (III, IV and V) presented less mutagenic activity compared to compounds I, II and VI according to the salmonella mutagenicity assay (Ames test). Compounds IV and VI showed activity in K562 culture cells, with increases in gamma globin gene expression to levels higher than with hydroxyurea suggesting a potential to increase fetal hemoglobin. This data set characterizes new potentially useful drug candidates for the treatment of symptoms of sickle cell anemia.

Zoneamento geoambiental aplicado ao planejamento da gestão ambiental e territorial do município de Colorado D'Oeste, RO

This research is based on the physical characterization of the environment to support definition of the best land use for the county of Colorado D'Oeste, in State of Rondônia, Brazil. Remote sensing and geoprocessing techniques were applied to support the preparation of a Geoenvironmental Zoning, which was used to define strategies of territorial and environmental management in that county. Digital and analogical remote sensing products, acquired by satellites, and additional cartographic and thematic maps allowed a morphostructural analysis to define low and high structural associated study site tectonic. Subsequently, this information was used to support analysis of the physiographic compartmentation of the study area. Based on this study information, it is possible to define geoenvironmental subzones and local hidrological regime, soils, mineral components, texture, color, and sedimentary materials. By integrating previous described information, a synthesis cartographic map generated. Accordingly, this Cartographic Sheet spatially defined the best land use over the study area, indicates zones for conservation, agricultural, and regeneration (areas that should be recovered). Finally, the results of this research can contribute and support governmental and non-governmental organization and local communities could improve land use and soil management, avoiding natural resource destruction and future land scarcity in the county of Colorado D'Oeste.

Planejamento em saúde bucal no município de João Pessoa, Estado da Paraíba: o cirurgiãodentista enquanto protagonista da atenção básica

The aim was to identify the perception of Oral Health Planning (OHP) of basic care (BC) dental surgeons (DSs) in João Pessoa, Paraíba State, Brazil. Seventeen BC DSs from João Pessoa were interviewed. A qualitative analysis was performed using the Discourse of the Collective Subject (DCS) methodology. DCS obtained: Impact - My work is effective when the user's need remains at the BC. Social Control - The population participates in the organization of promotional activities, but I think it doesn't have enough maturity to opine on OHP. OHP Basis and Organization - The OHP has a diverse organization and is based on user needs. It can be concluded that the knowledge of the DSs on OHP is varied. There is limited understanding about problem-solving. Social control is considered incipient and weak. It is understood that the organization of the local OHP assumes a diverse character and should be based on user demands.

Crescimento, comportamento ingestivo e desempenho reprodutivo de novilhas mestiças holandês x zebu, em pastejo, submetidas à suplementação protéica durante a época das águas

The objective of this study was to evaluate the effect of supplemental protein during the rainy season on body growth, ingestive behavior and reproductive performance of crossbred Gir x Holstein dairy heifers, with mean age of 21 ± 4.1 months and average initial body weight of 296.7 ± 57.3 kg, distributed in a completely randomized design with four treatments and six replicates per treatment. Heifers remained on Brachiaria brizantha cv. Marandu pasture, managed according to a rotational grazing system and, as treatment, it was supplemented with protein concentrate (34%, 43%, 56% and 66% BW) and level of supply of 0.30% body weight (BW). The animals were weighed and the mean weight of the lot was used for the calculation of adjustment of the amount of concentrate offered. Heifers that reached 330.0 kg of live weight were artificially inseminated and, 45 days after insemination, pregnancy diagnosis was performed for the calculation of pregnancy rate and age at conception. No significant difference of protein levels was observed on grazing, eating behavior, productive performance and age at conception of dairy heifers on pasture. The average daily weight gain of BW and age at conception were, on average, 0.907 kg/animal and 24.03 months, respectively.

Potencial reprodutivo de Chrysoperla externa (Neuroptera: Chrysopidae): Efeito da proporção sexual e período de acasalamento

In this study the effects of the time of male permanence with females and different sex ratios on the reproductive capacity of Chrysoperla externa F 3 adults was evaluated. The insects were kept at 25 ± 2 °C, 70 ± 10% RH, under a 12 h photoperiod. The first experiment consisted of mating females with males that were subsequently removed after 5, 10, 15, 20, 25, 30, 35 and 40 days; the control group consisted of males remaining with the females during the entire experimental period. The second experiment consisted of mating: one male with one female (1:1); one male with two females (1:2); one male with three females (1:3); one male with four females (1:4); and one male with five females (1:5), and then evaluating their pre-ovipositioning periods, daily and total ovipositioning, egg viability percentages, and efficiency indices (which considered total ovipositioning, mean egg viability, and the ovipositioning period). It was found that alternating the sexual proportions from one male with one female to one male with three females did not alter the reproductive performance of these insects, and that there was no need to replace the males after five days as they were able to provide sufficient numbers of spermatozoa during this period to maintain consistent reproductive rates.
