    Insects have played an important role as human food throughout history, especially in Africa, Asia and Latin America. A good example of edible insects is the mealworm, Tenebrio molitor Linnaeus, 1758 (Coleoptera, Tenebrionidae), which are eaten in Africa, Asia, the Americas and Australia. This species is easily bred in captivity, requiring simple management. The bocaiuva (Acrocomia aculeata (Jacq.) Lodd) is an abundant palm tree found in the Brazilian Cerrado, providing fruits with high nutritional value. The aim of this work was to determine the chemical composition of T. molitor grown in different artificial diets with bocaiuva pulp flour. The nutritional composition, fatty acid composition, antioxidant activity, trypsin activity and anti-nutritional factors of larvae were analyzed. The results showed that mealworms grown on artificial diet with bocaiuva are a good source of protein (44.83%) and lipid (40.45%), with significant levels of unsaturated fatty acids (65.99%), antioxidant activity (4.5 μM Trolox/g of oil extracted from larvae) and absence of anti-nutritional factors. This study indicates a new source of biomass for growing mealworms and shows that it is possible to breed mealworms in artificial diet with bocaiuva flour without compromising the nutritional quality of the larvae.

    The macauba palm (Acrocomia aculeata) is native of tropical America and is found mostly in the Cerrados and Pantanal biomes. The fruits provide an oily pulp, rich in long chain fatty acids, and a kernel that encompass more than 50% of lipids rich in medium chain fatty acids (MCFA). Based on biochemical and nutritional evidences MCFA is readily catabolized and can reduce body fat accumulation. In this study, an animal model was employed to evaluate the effect of Acrocomia aculeata kernel oil (AKO) on the blood glucose level and the fatty acid deposit in the epididymal adipose tissue. The A. aculeata kernel oil obtained by cold pressing presented suitable quality as edible oil. Its fatty acid profile indicates high concentration of MCFA, mainly lauric, capric and caprilic. Type 2 diabetic rats fed with that kernel oil showed reduction of blood glucose level in comparison with the diabetic control group. Acrocomia aculeata kernel oil showed hypoglycemic effect. A small fraction of total dietary medium chain fatty acid was accumulated in the epididymal adipose tissue of rats fed with AKO at both low and high doses and caprilic acid did not deposit at all.

    The complex network of direct and indirect relationships determines not only the species abundances but also the community characteristics such as diversity and stability. In this context, seed predation is a direct interaction that affects the reproductive success of the plant. For Acrocomia aculeata, the seed predation by Pachymerus cardo and Speciomerus revoili in post-dispersal may destroy more than 70% of the propagules and is influenced by the herbivory of the fruits during pre-dispersal. Fruits of plants with a higher level of herbivory during pre-dispersal are less attacked by predators in post-dispersal. We proposed a hypothesis that describes this interaction as an indirect defense mediated by fungi in a multitrophic interaction. As explanations, we proposed the predictions: i) injuries caused by herbivores in the fruits of A. aculeata favor fungal colonization and ii) the colonization of A. acuelata fruit by decomposing fungi reduces the selection of the egg-laying site by predator. For prediction (i), differences in the fungal colonization in fruits with an intact or damaged epicarp were evaluated in fruits exposed in the field. For prediction (ii), we performed fruit observations in the field to determine the number of eggs of P. cardo and/or S. revoili per fruit and the amount of fungal colonization in the fruits. In another experiment, in the laboratory, we use P. cardo females in a triple-choice protocol. Each insect to choose one of the three options: healthy fruits, fruits with fungus, or an empty pot. The proposed hypothesis was corroborated. Fruits with injuries in the epicarp had a higher fungal colonization, and fruits colonized by fungi were less attractive for egg-laying by seed predators. This study emphasizes the importance of exploring the networks of interactions between multitrophic systems to understand the dynamics and maintenance of natural populations.

    Full Text Available Macaúba (Acrocomia Aculeata is a palm tree typical of the Brazilian savanna with great socioeconomic interest due to its high capacity of vegetable oil production with high levels of fatty acids. This paper evaluated the technical viability of saponified macaúba’s nut oil (SMNO as a collector in apatite’s micro flotation in Hallimond tube, being the oil chemically characterized and saponified before its utilization. Tests were performed varying the solution pH (8, 9 and 10 and collector concentration (2.5, 5.0, 7.5 e 10 mg/L. To compare the obtained results with SMNO the industrial collector Clariant’s Flotigan 5806 was used in the same tests conditions. Results shows that SMNO reached the highest recoveries rates of apatite in pH 8 and 9, particularly at the concentrations 7.5 and 10 mg/L. When compared to Flotigam 5806, the MNO showed lower recoveries at all pHs and concentrations tested.

    Full Text Available ABSTRACT Reserve mobilization in seeds occurs after visible germination, which is marked by the protrusion of the radicle or cotyledonary petiole, as in species of Arecaceae. Acrocomia aculeata (macaw palm, usually produces hard seeds whose endosperm has mannan-rich cell walls. We investigated the composition of storage compounds in macaw palm seed and the roles of two enzymes (endo-β-mannanase, α-galactosidase during and after germination. The seeds were firstly submitted to pre-established protocol to overcome dormancy and promote germination. Enzyme activity in both embryo and endosperm were assayed from the initiation of germinative activities until leaf sheath appearance, and the status of seed structures and reserve compounds were evaluated. Protein content of the embryo decreased with the initiation of imbibition while the lipid content began decreasing six days after removal of the operculum. Increases in enzyme activity and starch content were both observed after visible germination. We suggest that endo-β-mannanase and α-galactosidase become active immediately at germination, facilitating haustorium expansion and providing carbohydrates for initial seedling development. Protein is the first storage compound mobilized during early imbibition, and the observed increase in the starch content of the haustorium was related to lipid degradation in that organ and mannan degradation in the adjacent endosperm.

    Full Text Available Insect consumption as food is culturally practiced in various regions of the world. In Brazil, there are more than 130 species of edible insects registered, from nine orders, among which stands out the Coleoptera. The larva of the beetle Pachymerus nucleorum Fabricius, 1792, grows into the bocaiuva fruit (Acrocomia aculeata (Jacq. Lodd. Ex Mart., 1845, which has proven nutritional quality. The aim of this work was to evaluate the nutritional potential of P. nucleorum larvae compared to bocaiuva kernels for human consumption. Proteins were the second largest portion of the larvae nutritional composition (33.13%, with percentage higher than the bocaiuva kernels (14.21%. The larval lipid content (37.87% was also high, very close to the kernels (44.96%. The fraction corresponding to fatty acids in the oil extracted from the larvae was 40.17% for the saturated and 46.52% for the unsaturated. The antioxidant activity value was 24.3 uM trolox/g of oil extracted from larvae. The larvae tryptic activity was 0.032±0.006 nmol BAPNA/min. Both the larvae and the bocaiuva kernel presented absence of anti-nutritional factors. These results favor the use of P. nucleorum larvae as food, which are a great protein and lipid sources with considerable concentrations of unsaturated fatty acids compared to the bocaiuva kernel.

    The Macauba palm (Acrocomia aculeata (Jacq.) Lood. ex Mart) is a native oil palm of the tropical America growing in anthropic areas, especially in grazing lands of Brazilian Cerrado. Macauba palm displays intense fruiting which results in high fruit and oil yield (3.0 - 6.0 ton/ha/year). The main Macauba palm differentials are: it is adapted to the environment with marked water restriction (1000 mm annual precipitation) which makes it resistant to drought and it does not compete with areas of rainforest; the oil is similar in composition to the African palm oil (Elaeis guineensis Jacq.) and can be used in several industrial applications such as biofuels, food, cosmetics, pharmaceutics and oil chemistry. Additionally, Macauba fruit processing generates several by-products like edible pulp bran, high-protein edible kernel bran, dense endocarp biomass, and husk biomass, all valuable products. Today, 172 million hectares of Brazilian land are used for grazing, of which 30 million hectares of these lands are degraded due to poor land use, 6 million in the state of Minas Gerais, in Brazil. Macauba could be cultivated in these degraded lands and is a candidate to become the main raw material for production of biokerosene. A new productive chain is forming in Brazil, the first commercial plantation of Macauba was implemented last year in Minas Gerais state and it is important to estimate the environmental impacts of this plantation, in terms of carbon (C) allocation. There is a lack of experimental data on Macauba carbon allocation and this study aimed to estimate the carbon allocation (leaves, stems and roots) of Macauba palm. The results suggest that Macauba palm is important in contributing to the carbon allocation.

    Full Text Available With increasing demands for biodiesel in Brazil, diverse oil feedstocks have been investigated for their potentials for biodiesel production. Due to the high biodegradability of natural oils and their respective biodiesels, microbial growths and consequent deterioration of final product quality are generally observed during storage. This study was aimed at evaluating the susceptibility of Acrocomia aculeata pulp oil and Jatropha curcas oil as well as their respective biodiesels to biodeterioration during a simulated storage period. The experiment was conducted in microcosms containing oil/biodiesel and an aqueous phase over 30 d. The levels of microbial contamination included biodiesel and oil as received, inoculated with fungi, and sterile. Samples were collected every 7 d to measure pH, surface tension, acidity index, and microbial biomass. The initial and final ester contents of the biodiesels were also determined by gas chromatography. The major microbial biomass was detected in A. aculeata pulp and J. curcas biodiesels. Significant reductions in pH values were observed for treatments with A. aculeata pulp biodiesel as a carbon source (p

    In Brazil, the conservation of water resources and agricultural soil are key environmental and economic aspects to mantain land services and the quality of life people in rural and urban communities. The macaw - Acrocomia aculeata) (Jacq.) Lodd. (Ex Martius) - is a Brazilian native oleaginous palm, whose potential has been highlighted in the scientific community due to its high economic potential and its recent advances in crop farming. This study aims to quantify the runoff in macaw plantation, comparing different techniques of crop management for a period of one year (from September 2012 to August 2013). The data from this study were collected in the Experimental Farm of the Federal University of Viçosa (UFV) located in the municipality of Araponga, MG, Brazil. The seedlings took place in February 2009, in holes, spaced 5X5 in an area of 1.7 ha (680 plants) with a slope of 25%. Rainfall was monitored through three pluviometers with expose area of 162.86 cm² whereas the impact of different management systems on runoff was measured by using 10 plots of 63 m² each: 3 treatments with three repetitions plus the control plot. Each plot presented four macaw plants. The treatment one (T1), was formed by macaw plants without using any soil conservation technique; the treatment two (T2) consisted of macaws with a contour cord with 40 cm wide by 30 cm deep, located between the plantation lines; for the treatment three (T3) beans were planted forming vegetation strips; the control (T0) was represented by a portion without macaws plants, with spontaneous vegetation growing throughout the plot, which was not used any soil conservation technique. T2 presented the lowest values of runoff during the twelve months and at the same time, the greatest requirements of initial rainfall for runoff generation. In contrast, T3 showed the highest volumes of runoff for the study period, with a small reduction with the exception of January and February 2013, when the bean plants were well

    Full Text Available This study evaluated mechanisms of the dehydration and rehydration of fruits and seeds on the resulting embryo viability of the macaw palm, Acrocomia aculeata (Jacq. Loddiges ex Mart. Dehydration was performed in a forced-air oven at 37 ± 2°C for 0, 3, 6, 9, 12 or 15 days, and after these periods, the embryo viability was evaluated by the tetrazolium test. The effect of hydration on the germination percentage and velocity index was evaluated by the imbibition of seeds with distilled water in a germinator at 30 ± 2°C for 0, 2, 4, 6, 8 or 10 days. The seeds were then treated with fungicide and maintained in a Mangelsdorf germinator at 30 ± 2°C. Drying caused a progressive water loss in the fruits and facilitated the extraction of the seeds. Fruits subjected to drying for up to nine days had no loss of vigor; however, after dehydration for 15 days, a loss in seed viability was observed. Simple linear regression estimated the seed water content based on the fruit water content. Seed imbibition in distilled water favored an increase in dead by fungally contaminated seeds.Objetivou-se com esse estudo elucidar os mecanismos de desidratação e hidratação de frutos e sementes na viabilidade de embriões de macaúba Acrocomia aculeata (Jacq.

    Full Text Available Babaçu (A. speciosa, Buriti (M. flexuosa, and Macaúba (A. aculeata are palm trees typical of the ecotone area between Cerrado and the Amazon rainforest. The purpose of this study was to evaluate the antimicrobial potential of the extracts prepared from the leaves of those palms as well as determine their chemical compositions. The ethanol extracts were prepared in a Soxhlet apparatus and tested by disk diffusion and agar dilution technique against Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, and Candida parapsilosis. However, there was no significant activity at concentrations of 25, 50, and 100 mg·Ml−1. Moreover, the phytochemical analysis revealed the presence of tannins, flavonoids, catechins, steroids, triterpenes, and saponins. Gas chromatography (GC/MS analysis also identified organic acids, such as capric (decanoic acid, lauric (dodecanoic acid, myristic (tetradecanoic acid, phthalic (1,2-benzenedicarboxylic acid, palmitic (hexadecanoic acid, stearic (octadecanoic acid, linoleic (9,12-octadecadienoic acid (omega-6, linolenic (octadecatrienoic acid (omega-3, and the terpenes citronellol and phytol. Based on the chemical composition in the palm leaf extracts, the palms have the potential to be useful in the food, cosmetic, and pharmaceutical industries.

    Full Text Available Abstract Pereskia aculeata Mill., a species of the family Cactaceous, popularly known in Brazil as ora-pro-nobis, has high protein, vitamin and mineral contents. High essential amino acid concentrations should be underscored, suggesting a better evaluation of the fractions. Current study quantifies amino acid content and the chemical score (CS of protein amino acids, determining in vivo digestibility, protein efficiency ratio (PER and net protein ratio (NPR of P. aculeata. Plant material was collected, washed, placed in an oven at 60 °C, ground and stored in a freezer for chemical analysis. Diets that maintain isoproteic and isocaloric characteristics were prepared for the bioassay, namely: casein (no protein and Pereskia aculeata leaves-based flour. Eighteen male albino Wistar rats, divided into three experimental groups of 6 animals each, were used to evaluate protein quality and bioavailability of micronutrients. Pereskia aculeata flour provided as a single source is inadequate for growth, although it is relevant for maintaining protein metabolism indicated by net protein ratio (2.87. It is actually a good quality protein source due to few limiting essential amino acids, and it meets the diet requirements for humans.

    Full Text Available The aim of the present study is to investigate the antioxidant properties of the lichen Cetraria aculeata. Antioxidant activity of the methanol and ethyl acetate extracts of lichen was tested by different methods including determination of total phenolics content, determination of total antioxidant capacity, DPPH free radical scavenging activity, inhibitory activity towards lipid peroxidation, ferrous ion chelating ability and hydroxyl radical scavenging activity. The extracts of the lichen C. aculeata showed significant antioxidant activity. The methanol extract showed higher values for total phenolics and total antioxidant capacity compared to the ethyl acetate extract, while the ethyl acetate extract demonstrated better results for DPPH radical scavenging, inhibitory activity towards lipid peroxidation, chelating ability and hydroxyl radical scavenging than the methanol extract. This is the first report of the antioxidant properties of Cetraria aculeata growing in Serbia. The results of antioxidant activity indicate the application of this lichen as source of natural antioxidants that could be used as a possible food supplement, in the pharmaceutical industry and in the treatment of various diseases.

    Pereskia aculeata is a Cactaceae plant with valuable nutritional properties, including terrific amounts of protein, minerals, vitamins, and fiber. However, P. aculeata is reported to contain antinutrients and alkaloids in its leaves. In addition, in a study on growth and development, Wistar rats fed with P. aculeata and casein as protein source grew less than the control group (fed with casein only). Therefore, in this study, we evaluated, for the first time, the oral acute toxicity of P. aculeata in rats and also the cytotoxicity behavior of the plant on lettuce seeds. The acute toxicity research was carried out using dried P. aculeata ethanolic extract, in three different doses, administered by gavage to 24 female Wistar rats. The rats were then examined for signs of toxicity, food intake, body weight, and fecal excretion fluctuations, as well as histopathological alterations, using eight different body tissues. The acute toxicity study did not show any difference among the groups in either clinical evaluation or histopathological analyses. For the cytotoxicity study, dried P. aculeata ethanolic extract was applied on lettuce seeds in five different concentrations. These seeds were evaluated for germination, root and shoot length, and mitotic index. The results show that P. aculeata extract affects lettuce root and shoot growth, but not germination or mitotic index. In conclusion, the acute toxicity on rats and the cytogenotoxicity on lettuce of P. aculeata are neglectable, validating the potential of this plant to be used as a functional food.

    The plastome of macaw palm was sequenced allowing analyses of evolution and molecular markers. Additionally, we demonstrated that more than half of plastid protein-coding genes in Arecaceae underwent positive selection. Macaw palm is a native species from tropical and subtropical Americas. It shows high production of oil per hectare reaching up to 70% of oil content in fruits and an interesting plasticity to grow in different ecosystems. Its domestication and breeding are still in the beginning, which makes the development of molecular markers essential to assess natural populations and germplasm collections. Therefore, we sequenced and characterized in detail the plastome of macaw palm. A total of 221 SSR loci were identified in the plastome of macaw palm. Additionally, eight polymorphism hotspots were characterized at level of subfamily and tribe. Moreover, several events of gain and loss of RNA editing sites were found within the subfamily Arecoideae. Aiming to uncover evolutionary events in Arecaceae, we also analyzed extensively the evolution of plastid genes. The analyses show that highly divergent genes seem to evolve in a species-specific manner, suggesting that gene degeneration events may be occurring within Arecaceae at the level of genus or species. Unexpectedly, we found that more than half of plastid protein-coding genes are under positive selection, including genes for photosynthesis, gene expression machinery and other essential plastid functions. Furthermore, we performed a phylogenomic analysis using whole plastomes of 40 taxa, representing all subfamilies of Arecaceae, which placed the macaw palm within the tribe Cocoseae. Finally, the data showed here are important for genetic studies in macaw palm and provide new insights into the evolution of plastid genes and environmental adaptation in Arecaceae.

Population study of Crepidula aculeata Gmelin, 1791 (Gastropoda Calyptraeidae and analysis of protocooperative association between the mollusc and the alga were carried out in the phytal of calcareous alga Amphiroa beauvoisii Lamouroux, 1816 at Ilha das Palmas, Santos Bay (24º00'S - 46º19'W. Samples were collected at three sites of different degree of water movement in the intertidal zone and sublittoral fringe during 1975 and 1976. From 93,916 organisms belonging to 172 species, 5,331 were Crepidula, the most abundant among sessile species. Also, Crepidula constitutes a substratum to attachment of Amphiroa, accounting for 30% of total phytal area. There was a positive correlation between the growth of shell and epizoic alga. Higher level of the phytal belt was more suitable for attachment and/or growth of the epizoic alga, without influence from water movement or season of the year. This association depends on the external morphology of the shell, filter-feeding habit, high adhesive power and lacking of mechanisms avoiding attachment of epizoics of Crepidula. Exuberant growth of the epizoic tuft over Crepidula female shell would constitute camouflage and protection of offsprings against predators.

    Full Text Available In Mexico, medicinal plants are widely used. The use of Randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. Interviews were carried out in Jamapa, Veracuz, Mexico, with local residents to collect information about the traditional use of Randia aculeata. In this locality, seven pieces of fruit from the plant are mixed in a liter of alcohol, and then administered orally against snakebites. By using histological techniques and a murine model, we explored its cytoprotective properties against the effects of Crotalus simus and Bothrops asper venoms. Possible protections provided by the plant against tissue damage to skeletal and cardiac muscles and against the typical loss of red blood cells were analyzed. Randia aculeata caused an increase in microhematocrit and total hemoglobin, parameters that are often decremented in association with the loss of red blood cells, which is a characteristic effect of animal venom. Randia aculeata was also shown to protect against the lowering of platelet levels caused by Bothrops asper venom. Finally, Randia aculeata produced a partial inhibition of necrosis following administration of snake venom in skeletal and myocardial muscles. The present results provide solid evidence for the traditional use of Randia aculeata against snakebites, as demonstrated by protection against muscular tissue damage and the diminution of red blood cells.

    2018-02-01

    There are several possible causes of aggregated nesting in solitary Aculeata, one being joint defense against parasites. We tested whether females prefer nesting in aggregations, even if they consist of heterospecifics. We compared the colonization and nesting parasitism of trap-nests with and without a red mason bee aggregation. The results did not support our hypothesis that females prefer nesting in aggregations. The numbers of wild Aculeata nests did not differ between trap-nests with and without an aggregation. Unexpectedly, parasitism rates were higher in trap-nests with aggregations. When analyzing only nests of wild insects (mostly wasps), the differences in parasitism disappeared. Natural nesting sites may be such a limited resource that females nested in the first trap-nest they encountered and did not discriminate between our treatments, or wasps might share too few parasites species with bees to benefit from joint nest defense.

    Pereskia aculeata and Pereskia grandifolia have been studied widely due to their high nutritional and therapeutic values. However, little is known about the biological requirements of their seeds for the various germination factors. Thus, this experiment aimed to evaluate the thermal effects on the germination of these species at the temperatures of 24°C, 27°C, 30°C, 33°C and 36°C. After verification of the existence of differences in the performance of germination, a non-linear regression was carried out, relating the germination to temperature and identifying its point of maximum efficiency. We found that the lowest synchronization indexes of germination were observed close to 30°C. The best germination response of the P. aculeata and P. grandifolia was observed at 30°C and 33°C, respectively, with greater germination strength and fewer days to attain 63.21% of germinations. The results obtained from the germination of P. aculeata and P. grandifolia can be described by the Weindull distribution model with three parameters, as proposed by Carneiro and Guedes (1992).

  20. Biogeography and ecology of Cetraria aculeata, a widely distributed lichen with a bipolar distribution

    Directory of Open Access Journals (Sweden)

    2013-04-01

    Full Text Available Ecological and historical biogeography of lichens have rarely been studied in a concerted effort, but both aspects have to be taken into consideration when explaining the distributional patterns of species. This review summarizes, partly preliminary, results from a series of studies on phylogeography, ecophysiology and symbiotic interactions of the lichen Cetraria aculeata. This species is not only widespread but also occupies a very wide ecological niche. Evidence suggests that Cetraria aculeata has evolved and diversified in the Northern Hemisphere and colonised the Southern Hemisphere from there. Genetic isolation of populations indicates the absence of ongoing long range dispersal and genetic exchange between geographically isolated populations. We observe a hitherto unrecognized genetic diversity that may indicate ecotypic differentiation and speciation processes. Mediterranean and Polar populations differ not only genetically, but also in ecophysiological properties. Ongoing common garden experiments will have to show whether genetically fixed adaptation or acclimation is responsible for these differences. The genetic structure of the photobiont is best explained by climatic differences between localities, but co-dispersal with the mycobiont plays an important role as well. Taken together, these results indicate that a photobiont switch in the past enabled C. aculeata to widen its ecological niche, with subsequent genetic isolation of populations. Photobiont switches may play a crucial role in speciation processes of lichens. A combination of ecophysiological and phylogeographic studies with experimental approaches is necessary to better understand the reaction of lichens to changing environmental conditions.

    Nutritional evaluation and effect of sesbania aculeata, a salt-tolerant plant was evaluated by estimating the nutritive components (crude ash CA, crude protein CP, crude fiber CF, crude lipid CL, neutral-detergent fiber NDF, acid-detergent fiber ADF and crude lignin acid-detergent lignin ADL); and the in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), net energy lactation (NEL) and gross energy (GE). The effects of feeding Sesbania aculeata hay (whole plant) on live-weight, reproductive performance during several reproductive stages and on the serum progesterone levels in the blood of Damascus does were also determined. Results showed that nutritive components of Sesbania aculeata (whole plant) were (g/kg dry matter): CA 76, CP 144, CF 341, CL 23, NDF 562, ADF 435 and ADL 72. IVOMD was 50.7%, and values (MJ/kg dry matter) were: GE 28.27, ME 6.84 and NEL 3.50. Dry matter and crude protein yields of Sesbania hay were 8269 and 1190 kg/ha, respectively; and the energy produced (MJ/ha) was: GE 2338, ME 799 and NEL 607. Sesbania had no effects on mating rate (100%), duration of pregnancy (148.8 ±1.5 days), birth weight (4.6±1.1 kg) or weaning weight (18.8±5.0 kg) of kids. There was a pronounced effect of Sesbania on fertility rate since percentage of does that were mated but failed to conceive reached 50%. - Progesterone pattern in serum was normal in all does from feeding on Sesbania supplement until mating, and likewise was in does that had fertile matings; whereas, the pattern was abnormal in those in which they were mated, but failed to conceive.

    Eber Goulart Carvalho

    Full Text Available Physiologic growth parameters Wound healing Pereskia aculeata Mill., Cactaceae, is a cactus with high mucilage production, well-known for its nutritional properties. Folk use consists on skin injuries, and mucilage is probably involved in the wound healing activity. This work studied some aspects of its cultivation, specifically regarding soil (substrate, to correlate the effects of nutritional content to mucilage production and to the wound-healing property. Plants were grown under five different soil treatment (sand, crude soil, sand and soil, sand and cattle manure, soil and cattle manure, and after eight months extracts were prepared by turbo-extraction to obtain a crude hydroethanolic extract. We evaluated the effects of these extracts on swelling index, cytotoxicity, and in vitro wound healing property. The results show that the substrate used in cultivation may interfere with mucilage production, but not with cytotoxicity and wound healing, this shows the safety of its use, despite the soil treatment received along the various biomes where P. aculeata is cultivated. Furthermore, morphological studies demonstrated the beneficial effect of the mucilage-containing extract on the fibroblast cell culture, corroborating its folk use for wound healing.

    Full Text Available Considering that nitrogen is directly related to leaf protein content, the nitrogen fertilization in Pereskia aculeata plants may affect the protein content and increase its nutritional potential. This study aimed at assessing the effect of nitrogen fertilization on mineral, protein and nitrate contents, as well as the yield of P. aculeata leaves. A randomized blocks design was used, with three replications and five treatments, consisting of increasing topdressing nitrogen doses (0-400 kg ha-1, in soil with organic matter content of 4.0 dag kg-1. Three harvests were performed for leaf analysis. No significant effect was observed for mineral and protein content or leaf fresh mass yield. The mean values for mineral composition were: 3.52 dag kg-1 of N, 0.47 dag kg-1 of P, 4.65 dag kg-1 of Ca, 0.71 dag kg-1 of Mg, 0.25 dag kg-1 of S, 36.64 mg kg-1 of Zn and 174.13 mg kg-1 of Fe. The mean content for protein was 21.86 % and the leaf fresh mass yield was 0.971 kg plant-1. K levels decreased from 50 kg ha-1 of N. Nitrate increased linearly with the nitrogen fertilization, reaching a maximum value of 78.2 mg kg-1 of fresh mass, well below the health risk threshold. It was concluded that a soil with high organic matter content does not require nitrogen fertilization. However, doses up to 400 kg ha-1 of nitrogen ensure adequate leaf yield and protein and mineral contents within the desired range for the species, being a food rich in proteins, iron and calcium.

    Full Text Available Con el fin de obtener un diagnóstico del estado actual de conocimiento sobre usos de las palmas en la Amazonia colombiana, se revisaron las principales fuentes de información. Treinta y seis de las 41 etnias indígenas consideradas tuvieron registros de uso. Se registraron 82 especies de palmas usadas (78% de las potenciales y 165 usos distribuidos en ocho categorías; todos los usos se presentan de manera detallada en un catálogo. Las categorías de uso más importantes fueron: utensilios y herramientas, construcción, y alimentación humana. Las diez especies más importantes fueron Bactris gasipaes, Euterpe precatoria, Mauritia flexuosa, Oenocarpus bataua, Attalea maripa, Oenocarpus minor, Astrocaryum chambira, Iriartea deltoidea, Oenocarpus bacaba y Socratea exorrhiza; la mayoría de ellas también han sido registradas como las más importantes en otras partes del Neotrópico. No se encontró ninguna información sobre usos de palmas para varios grupos indígenas, especialmente para las etnias cocama, letuama, piaroa, pisamira y yurí, para las cuales se requieren investigaciones detalladas. Se concluye que a pesar de los vacíos de información, los resultados muestran que las palmas son un recurso muy importante con un gran potencial, y una pieza fundamental para la seguridad alimentaria y el desarrollo sustentable de la Amazonia colombiana. Sugerimos la inclusión de las especies más importantes en programas de manejo y agroforestales, al igual que la implementación y popularización de técnicas de cosecha no destructivas. Recomendamos además que las investigaciones futuras estén enfocadas en desarrollar estrategias de manejo que garanticen el uso sostenible de todas estas especies útiles.

  12. Family structure and dynamics in DePalma's horror films.

    Science.gov (United States)

    Gordon, N G

    1983-01-01

    An analysis of the familial relationships in Brian DePalma's five major horror films reveals a persistent unconscious fantasy formation involving the nuclear family. These single-parent, only-child families are all tragically destroyed because of an inability to adequately mourn the absent parent. Although the asexual young adults in the films are spared the completely disastrous effects of madness and violence, they are still psychologically traumatized. This hidden subtextual theme involving the family parallels DePalma's bleak view of authority figures outside the home, as well as American society in general. Adequate identity formation requires that people both inside and outside the family accept the adolescent as a separate person. The grim psychological truth threading its way throughout DePalma's horror films is that these young adults are psychically devastated by the effects of a primitive, fused symbiotic relationship in interaction with a society that does not provide an adequate role for the developing person. Consequently, their attempt to psychologically move outside the family, which includes the maturation of their sexuality, results in the destruction of the family itself.

    Pereskia aculeata Miller is a native cactus that can be found in Brazil and is called 'ora-pro-nobis' (OPN). Many people from poor communities consume the dark green leaves of OPN as a vegetable. The objective of the present work was to evaluate the nutritional components in terms of proximate composition, minerals, vitamins, protein content and their in vitro protein digestibility. OPN leaves showed remarkable levels of total dietary fiber (39.1% dry basis), minerals (calcium, magnesium, manganese and zinc) and vitamins (vitamin A, vitamin C and folic acid). Among amino acids, tryptophan was the most abundant (20.5% of the total amino acids) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis showed small peptides, inferior to 6.5 kDa, and four major bands (61 kDa, 53 kDa, 33 kDa, and 15 kDa). The protein digestibility corrected amino acid score showed the lowest value of sulfur-amino acids (Met+Cys). OPN leaves could be considered a good source of minerals, vitamins and amino acids, and may serve as a potential functional ingredient.

    Full Text Available Pereskia aculeata Mill., popularly known in Brazil as “Ora-pro-nobis”, is an unconventional edible vegetable. Taking into account its potential for agronomic cultivation, this study aimed to evaluate the growth response of this plant under intermittent drought through controlled reductions in the substrate matric potential, in a greenhouse. Treatments consisted of adding to the pots a volume of water to raise the matric potential to -5 kPa, according to the water retention curve in the substrate, whenever the mean substrate matric potential reached values between -10 kPa and -70 kPa, depending on the treatment. At 140 days after transplanting, leaf area and dry mass of leaves, stems and roots were determined. The intermittent reduction of the matric potential in the root zone of “Ora-pro-nobis” affected less the dry mass accumulation in leaves (reduction of 21.4% than in stems (reduction of 48.1% and roots (reduction of 63.7%, and that is interesting because leaves are the main commercial product of this plant. The treatment also modified the proportionality of dry mass allocation among plant parts and reduced the photosynthetic efficiency of leaves, fact evidenced by the linear increase of the specific leaf area (0.63 cm2 g-1kPa-1 and leaf area ratio (0.39 cm-2 g-1kPa-1, although not affecting directly the leaf area.

    An extract of the red alga, Neorhodomela aculeata, exhibited antiviral activity against human rhinoviruses. Bioassay-guided purification was performed to yield six compounds, which were subsequently identified as lanosol (1) and five polybromocatechols (2-6) by spectroscopic methods, including 1D and 2D NMR and mass spectrometric analyses. Structurally, all of these compounds, except compound 5, contain one or two 2,3-dibromo-4,5-dihydroxyphenyl moieties. In a biological activity assay, compound 1 was found to possess antiviral activity with a 50% inhibitory concentration (IC₅₀) of 2.50 μg/mL against HRV2. Compound 3 showed anti-HRV2 activity, with an IC₅₀ of 7.11 μg/mL, and anti-HRV3 activity, with an IC₅₀ of 4.69 μg/mL, without demonstrable cytotoxicity at a concentration of 20 μg/mL. Collectively, the results suggest that compounds 1 and 3 are candidates for novel therapeutics against two different groups of human rhinovirus.

    Full Text Available Pereskia aculeata Mill. (Ora-pro-nóbis is a native cactaceae from tropical America, whose leaves have high protein content. In Brazil it is found in all territorial extension between the states of Bahia and Rio Grande do Sul. Most studies have focused on chemical characterization of the leaves of this specie. The objective was to assess the carotenoids profile and the total polyphenols present in the fruits of P. aculeate. Carotenoids were determined by HPLC-PAD (high performance liquid chromatography - photodiode array detector, total polyphenols were determined by Folin-Ciocalteu and vanillin methods. Trans-β-carotene was the main carotenoid, followed by α-carotene, lutein and other minor carotenoids. It was found 64.9 ± 1.1 mg.100g-1 of gallic acid equivalent, 14.8 ± 0.2 mg.100g-1 of catechin equivalent. Carotenoid identification of P. aculeate fruits are presented here by the first time and indicate that these fruits can be researched as source of bioactive substances, especially antioxidant and provitamin A carotenoids.

Se establecieron 14 transectos (1.5 ha en Tutunendo y 12 transectos (1 ha en Angostura, y en cada uno se registraron e identificaron las palmas, incluyendo todos los tamaños (plántulas, juveniles y adultos; además, se indagó sobre nombres comunes y usos de cada especie, entrevistando a 16 hombres mayores de 45 años y conocedores del bosque. La riqueza de palmas encontrada en las localidades estudiadas (29 especies en 1.5 ha y 23 especies en 1 ha, está entre las más altas registradas para el Neotrópico, y corrobora el patrón de distribución de riqueza ligado a altas precipitaciones. La mayoría de las especies están representadas por pocos individuos, mientras que unas pocas son las más abundantes y frecuentes. Se identificó un grupo de especies (Wettinia quinaria, Welfia regia, Iriartea deltoidea, Socratea exorrhiza, Oenocarpus bataua, en el dosel, y Geonoma cuneata, en el sotobosque, que son particularmente importantes a nivel ecológico, y que caracterizan y modelan la vegetación, no sólo del área de estudio, sino también, al parecer, a lo largo de la región del Chocó Biogeográfico. Con base en los resultados y en otros datos florísticos, se plantea que, si bien las palmas son importantes a todo lo largo de la región, la mayor abundancia y riqueza parece presentarse hacia la zona central, que coincide con un aumento en el gradiente de precipitación. Veintisiete de las 33 especies encontradas tenía algún uso en una de las siete categorías de uso, lo cual muestra la importancia de las palmas para las poblaciones locales.

    The coagulating properties of aqueous crude extracts and purified proteins of Vigna unguiculata and Parkinsonia aculeata seeds, which are traditional water coagulants in rural areas of Tanzania, were studied. The coagulation activity assays were done using one millilitre (ml) of kaolin water samples. Coagulating proteins were purified in two-step ion exchange chromatography. The properties of coagulant protein were compared with Moringa oleifera. Coagulating components eluted by 0.6 M NaCl in both coagulants are cationic proteins that have the molecular mass of about 6 kDa, which is very similar to that of M. oleifera. The proteins of V. unguiculata and P. aculeata eluted by 0.3 M NaCl also harbour coagulation activity but proteins eluted with 0.6 M NaCl have higher activity. The dosage for coagulation using purified proteins of both coagulants is about 5 to 10 times lower than that of crude seed extracts. The optimum floc settling time of water treated by crude seed extracts and purified proteins ranged between two and two and half hours. Coagulating proteins of both coagulants eluted by 0.6 M NaCl are thermoresistant and retained coagulation activity of 87% to 92% after boiling for two hours at 80 degrees C and one hour at 95 degrees C. Thermotolerant proteins of V. unguiculata eluted by 0.6 M NaCl and P. aculeata have wider pH range of 5.5 to 8.5 for coagulation activity than those of M. oleifera proteins. The present investigation reveals the possibility of using purified natural coagulants for water treatment to produce safe drinking water.

  6. Low genetic diversity in Antarctic populations of the lichen-forming ascomycete Cetraria aculeata and its photobiont

    Full Text Available Lichens, symbiotic associations of fungi (mycobionts and green algae or cyanobacteria (photobionts, are poikilohydric organisms that are particularly well adapted to withstand adverse environmental conditions. Terrestrial ecosystems of the Antarctic are therefore largely dominated by lichens. The effects of global climate change are especially pronounced in the maritime Antarctic and it may be assumed that the lichen vegetation will profoundly change in the future. The genetic diversity of populations is closely correlated to their ability to adapt to changing environmental conditions and to their future evolutionary potential. In this study, we present evidence for low genetic diversity in Antarctic mycobiont and photobiont populations of the widespread lichen Cetraria aculeata. We compared between 110 and 219 DNA sequences from each of three gene loci for each symbiont. A total of 222 individuals from three Antarctic and nine antiboreal, temperate and Arctic populations were investigated. The mycobiont diversity is highest in Arctic populations, while the photobionts are most diverse in temperate regions. Photobiont diversity decreases significantly towards the Antarctic but less markedly towards the Arctic, indicating that ecological factors play a minor role in determining the diversity of Antarctic photobiont populations. Richness estimators calculated for the four geographical regions suggest that the low genetic diversity of Antarctic populations is not a sampling artefact. Cetraria aculeata appears to have diversified in the Arctic and subsequently expanded its range into the Southern Hemisphere. The reduced genetic diversity in the Antarctic is most likely due to founder effects during long-distance colonization.

    In order to reduce the cost of bioethanol production from lignocellulosic biomass, we developed a tool for cell surface display of cellulolytic enzymes on the ethanologenic bacterium Zymobacter palmae. Z. palmae is a novel ethanol-fermenting bacterium capable of utilizing a broad range of sugar substrates, but not cellulose. Therefore, to express and display heterologous cellulolytic enzymes on the Z. palmae cell surface, we utilized the cell-surface display motif of the Pseudomonas ice nucleation protein Ina. The gene encoding Ina from Pseudomonas syringae IFO3310 was cloned, and its product was comprised of three functional domains: an N-terminal domain, a central domain with repeated amino acid residues, and a C-terminal domain. The N-terminal domain of Ina was shown to function as the anchoring motif for a green fluorescence protein fusion protein in Escherichia coli. To express a heterologous cellulolytic enzyme extracellularly in Z. palmae, we fused the N-terminal coding sequence of Ina to the coding sequence of an N-terminal-truncated Cellulomonas endoglucanase. Z. palmae cells carrying the fusion endoglucanase gene were shown to degrade carboxymethyl cellulose. Although a portion of the expressed fusion endoglucanase was released from Z. palmae cells into the culture broth, we confirmed the display of the protein on the cell surface by immunofluorescence microscopy. The results indicate that the N-terminal anchoring motif of Ina from P. syringae enabled the translocation and display of the heterologous cellulase on the cell surface of Z. palmae. (orig.)

    con síntomas iniciales de la enfermedad, palmas sospechosas
    de presentar la enfermedad y palmas sanas dentro y fuera de
    un foco. Se tomaron muestras de hojas, raíces y estípite para
    determinar las concentraciones de almidón, azúcares reductores,
    no reductores y totales. La concentración de azúcares
    reductores tuvo un incremento en las palmas con síntomas
    iniciales y sospechosos; los azúcares totales presentaron mayor
    concentración en las palmas sospechosas de tener la enfermedad
    con respecto a las palmas con síntomas iniciales. Los azúcares
    no reductores en los diferentes órganos evaluados tuvieron
    una concentración muy baja. Los resultados observados en la
    alteración del metabolismo de los carbohidratos en las palmas

    Full Text Available The 1677 volcanic eruption, located close to the town of Fuencaliente at the south end of La Palma, has been associated with the large volcanic cone of San Antonio, an emission centre showing relatively high energy phreatomagmatic phases. However, detailed geological mapping and a reinterpretation of available eye-witness accounts elearly prove the San Antonio emission centre to be a preexisting volcano related to an eruption that occurred several thousands years earlier. The 1677 eruption, or Volcán de Fuencaliente is a low magnitude eruption composed of a small strombolian vent and a cluster of aligned spatter vents. About 75-125 x 106 m3 of lavas from these spatter vents covered an area of 4.5 x 106 m2 and formed a wide coastal platform with 1.6 x 106 m2 of new land gained from the sea. This modest magnitude eruption is in better accord with the negligible damage caused to the area reported in the contemporary accounts. This revision of the 1677 eruption and its magnitude is relevant for the precise reconstruction of the recent volcanism of La Palma and the correct definition of volcanic hazards in the island.La erupción de 1677, localizada cerca de la población de Fuencaliente en el S de la isla de La Palma, ha sido asociada hasta ahora con el cono volcánico denominado San Antonio. Este centro de emisión presenta fases eruptivas de energía relativamente elevada. El estudio geológico de detalle de esta erupción y la reinterpretación de los relatos de la época indican que el volcán San Antonio es, en realidad, un aparato volcánico preexistente, relacionado con algún episodio eruptivo de varios miles de años de antigüedad. La verdadera erupción de 1677 o Volcán de Fuencaliente, es de baja magnitud y está formada por pequeños centros eruptivos estrombolianos y conos alineados de escorias. El volumen de lavas emitidas es de unos 75-125 x 106 m3 y cubre una extensión de aproximadamente 4.5 x 106 m2, de los cuales 1.6 x 106 m2

    Parkinsonia aculeata L. (Caesalpiniaceae) is a traditional ethnomedicine and has been used for the empiric treatment of hyperglycemia, without scientific background. Mechanistic analyses at molecular level from the antioxidant mechanism observed by P. aculeata are required. Herein the effects of the treatment by hydroethanolic extract partitioned with ethyl acetate of P. aculeata aerial parts (HEPa/EtOAc) in mice fed a high-fat diet that share many obesity phenotypes with humans were evaluated. The animals were treated orally with HEPa/EtOAc (125 and 250 mg/kg/day) and pioglitazone (5 mg/kg/day), for 16 days. After the treatment, HEPa/EtOAc reduced fasting serum glucose and insulin levels, as well as homeostasis model assessment for insulin resistance. In addition, an improvement in glucose intolerance was also observed. Indeed, a reduction in the circulating levels of TNF-α and IL-6 was also observed. Furthermore, at molecular level, it was demonstrated that the HEPa/EtOAc treatment was able to improve these physiological parameters, through the activation of peroxisome proliferator-activated receptor γ (PPARγ) per si, as well as the enhancement of antioxidant mechanism by an increase in PPARγ/Cu(2+), Zn(2+)-superoxide dismutase (CuZn-SOD) axis expression in liver and adipose tissue. In sum, P. aculeata is effective to improve insulin resistance in a mouse model of obesity and this effect seems to involve the antioxidant and anti-inflammatory mechanisms through the increase in PPARγ/CuZn-SOD axis expression.

    Since 2006, the European Near Earth Asteroids Research (EURONEAR) project has been contributing to the research of near-Earth asteroids (NEAs) within a European network. One of the main aims is the amelioration of the orbits of NEAs, and starting in 2014 February we focus on the recovery of one-opposition NEAs using the Isaac Newton Telescope (INT) in La Palma in override mode. Part of this NEA recovery project, since 2014 June EURONEAR serendipitously started to discover and secure the first NEAs from La Palma and using the INT, thanks to the teamwork including amateurs and students who promptly reduce the data, report discoveries and secure new objects recovered with the INT and few other telescopes from the EURONEAR network. Five NEAs were discovered with the INT, including 2014 LU14, 2014 NL52 (one very fast rotator), 2014 OL339 (the fourth known Earth quasi-satellite), 2014 SG143 (a quite large NEA), and 2014 VP. Another very fast moving NEA was discovered but was unfortunately lost due to lack of follow-up time. Additionally, another 14 NEA candidates were identified based on two models, all being rapidly followed-up using the INT and another 11 telescopes within the EURONEAR network. They include one object discovered by Pan-STARRS, two Mars crossers, two Hungarias, one Jupiter trojan, and other few inner main belt asteroids (MBAs). Using the INT and Sierra Nevada 1.5 m for photometry, then the Gran Telescopio de Canarias for spectroscopy, we derived the very rapid rotation of 2014 NL52, then its albedo, magnitude, size, and its spectral class. Based on the total sky coverage in dark conditions, we evaluate the actual survey discovery rate using 2-m class telescopes. One NEA is possible to be discovered randomly within minimum 2.8 deg2 and maximum 5.5 deg2. These findings update our past statistics, being based on double sky coverage and taking into account the recent increase in discovery.

  16. Home dispossession: the uneven geography of evictions in Palma (Majorca

    Directory of Open Access Journals (Sweden)

    2015-09-01

    Full Text Available Affordable housing, either owner-occupied or rented, is regarded as a key element of social reproduction. However, processes of housing commodification and financialization have increasingly resulted in precariatization of the population and the loss of the right to housing. In the Spanish case, neoliberal policies geared to the revalorization of built environments had caused a housing bubble of historical magnitude. Since it burst, a large number of households have been dispossessed of housing, clearly reflected in the avalanche of foreclosures and evictions that hit Spanish cities as the crisis unfolded. This paper focuses on the urban area of Palma (Majorca by analyzing the foreclosures exerted on home­owners and the evictions of tenants who, from the start of the crisis of 2008, have not been able to afford their mortgage payments or rents. These evictions and foreclosures are correlated with the social status of the urban areas affected. The results show that the increase of evictions and foreclosures has emerged unevenly around the city. While tenant evictions have affected all types of urban areas, foreclosures have become much more evident in urban areas of low social status.

    Full Text Available With the LANL multiphysics hydrocode SAGE, we have performed several two-dimensional calculations and one three-dimensional calculation using the full Navier-Stokes equations, of a hypothetical landslide resembling the event posited by Ward and Day (2001, a lateral flank collapse of the Cumbre Vieja Volcano on La Palma that would produce a tsunami. The SAGE code has previously been used to model the Lituya Bay landslide-generated tsunami (Mader & Gittings, 2002, and has also been used to examine tsunami generation by asteroid impacts (Gisler, Weaver, Mader, & Gittings, 2003. This code uses continuous adaptive mesh refinement to focus computing resources where they are needed most, and accurate equations of state for water, air, and rock. We find that while high-amplitude waves are produced that would be highly dangerous to nearby communities (in the Canary Islands, and the shores of Morocco, Spain, and Portugal, the wavelengths and periods of these waves are relatively short, and they will not propagate efficiently over long distances.

    Full Text Available This paper focuses on fresh fish trade networks found in the street markets of Palmas, capital of Tocantins state, Brazil, so as to identify the economic agents involved and the various geographical spaces which interact as a result of these networks. Fresh fish trade in Palmas takes place in distributor warehouses, grocery stores, supermarkets and hypermarkets, fish shops, and fishing communities, but it is street markets that constitute the most popular sale venues. Market sellers establish upstream supply networks with sectors in the fish food system (suppliers in primary and secondary production, distribution, and retail, whose interactions generate connections in Palmas (fishermen, distributors, retailers on a local scale, as well as connections with locations in Tocantins and Pará states (fishermen, fisheries, cold storage companies on a regional scale. Sellers also establish downstream trade networks with the end consumer at markets and with establishments in the food and small retail sectors, whose interactions produce mostly local connections, in Palmas and in the Luzimangues district (close to Palmas. Such connections are marked by consumption processes in these urban areas. Key-words: network, fresh fish trade, street markets.

    The effect of applied inorganic P and 32 P labelled Sesbania aculeata (dhaincha) as green manure on the yield and P utilization by maize (Zea mays L.) in soils of two long term experiments was studied in a greenhouse experiment. Significant increase in the drymatter yield and total P uptake was obtained with increasing level of applied sesbania and P fertilizer. The relationship between total P uptake and total P added as organic plus inorganic fertilizer was significant. The Sesbania application significantly increased per cent P derived from added plant material by the maize crop. It also enhanced P uptake and its utilization from fertilizer source. The addition of Sesbania in the absence and presence of inorganic P fertilizer improved P use efficiency. The direct beneficial effect of added organic P was significant only in its application on soils with lower level of residual P. The utilization of P by maize after addition of sesbania varied from 5 to 9 per cent. (author). 10 refs., 3 tabs

  4. Interaction between seed dormancy-release mechanism, environment and seed bank strategy for a widely distributed perennial legume, Parkinsonia aculeata (Caesalpinaceae).

    Parkinsonia aculeata (Caesalpinaceae) is a perennial legume with seeds that have hard-seeded (physical) dormancy and are potentially very long-lived. Seed dormancy is a characteristic that can both help maximize the probability of seedling establishment and spread the risk of recruitment failure across years (bet-hedging). In this study, dormancy-release patterns are described across the diverse environments in which this species occurs in order to test whether wet heat (incubation under wet, warm-to-hot, conditions) alone can explain those patterns, and in order to determine the likely ecological role of physical dormancy across this species distribution. A seed burial trial was conducted across the full environmental distribution of P. aculeata in Australia (arid to wet-dry tropics, uplands to wetlands, soil surface to 10 cm deep). Wet heat explained the pattern of dormancy release across all environments. Most seeds stored in the laboratory remained dormant throughout the trial (at least 84 %). Dormancy release was quickest for seeds buried during the wet season at relatively high rainfall, upland sites (only 3 % of seeds remained dormant after 35 d). The longest-lived seeds were in wetlands (9 % remained dormant after almost 4 years) and on the soil surface (57 % after 2 years). There was no consistent correlation between increased aridity and rate of dormancy release. The results suggest that physical dormancy in P. aculeata is a mechanism for maximizing seedling establishment rather than a bet-hedging strategy. However, seed persistence can occur in environmental refuges where dormancy-release cues are weak and conditions for germination and establishment are poor (e.g. under dense vegetation or in more arid micro-environments) or unsuitable (e.g. when seeds are inundated or on the soil surface). Risks of recruitment failure in suboptimal environments could therefore be reduced by inter-year fluctuations in microclimate or seed movement.

    This paper deals with the description of two new species of Horismenus Walker (Hymenoptera: Eulophidae) from Brazil, parasitoids of larvae of Adetus analis (Haldeman) (Coleoptera: Cerambycidae). Both species are similar to Horismenus steirastomae (Girault), a species that also parasitizes cerambycids. Adetus analis is a pest of Sechium edule (Jacq.) Swartz (Cucurbitaceae), a minor crop in Brazil, Argentina and U.S.A., but also feeds in stems of Pereskia aculeata Miller (Cactaceae), an ornamental plant that has become a problematic weed species in Africa, where it was introduced. The two new Horismenus species are described, diagnosed, and compared to H. steirastomae.

    Due to the inaccessibility of Earth's interior, xenoliths became the best possibility to study the chemical composition of the earth mantle as well as its various processes. Three samples out of the sample suite of mantle peridotites from San Antonio Volcano on La Palma, Canary Islands, have been chosen to illustrate three examples of diverse mantle metasomatic events. The first sample, a pyroxene-hornblende-peridotite, was influenced by an alkali-rich, silicic-hydrous undersaturated melt and/or fluid forming a conspicuous cross-cutting amphibole-apatite-dyke with several veins percolating through the rock. Forsterite content in olivine varies between 82.5 - 85.5 and 86.0 - 89.0, suggesting at least two different occurrences of metasomatic overprint. Clinopyroxenes are mostly found in association with amphibole and in textural equilibrium hinting that both minerals may have grown together, while orthopyroxene have only been found as remnant inclusions in olivine. These clinopyroxenes are Cr-Diopsides with En43.40-50.97-Wo43.99-48.64-Fs4.30-8.22 and Mg# between 85.54 and 92.36. Secondary clinopyroxenes are Ti-Augites with En39.86-46.81-Wo46.65-51.98-Fs5.86-8.72 and Mg# of 82.44 - 89.09. The second sample, a sp-dunite, is characterized by haüyne-bearing melt veins which clearly indicate host-basalt infiltration. The haüyne is always in contact with amphibole, spinel and clinopyroxene denoting that they have been formed at the same time because there is no evidence for reaction among these phases. The melt infiltration apparently took place prior to xenolith entrainment in the host basalt. Primary olivine has Fo content of 89.57 - 89.67 with NiO ranging from 0.32 - 0.334, in contrast Fo content in secondary olivine varies from 89.05 - 90.86 and NiO fluctuates between 0.24 - 0.31. Cr-Diopside compositions are in range of En41.63-47.05-Wo47.83-51-90-Fs4.93-6.64 and Mg# between 86.48 - 90.50. The third sample is also a sp-dunite and marked by a network of phlogopite

    2012-09-01

    Full Text Available The purpose of this paper is to reflect on the possibilities and challenges of Community Development Banks (CDBs as an innovative method of socioeconomic management of microcredit for poor populations. To this end, we will discuss the case of Banco Palmas in Conjunto Palmeiras in the city of Fortaleza, in the northeastern state of Ceará, as an empirical case study. The analyses presented here are based on information obtained from Banco Palmas between late 2011 and early 2012. In addition, previous studies by other researchers on the bank and other studies on CDBs were important. The primary data collected at Banco Palmas came from documents made available by the bank, such as reports and mappings. The analyses describe some of the characteristics of the granting of microcredit and allow one to situate it in the universe of microfinance and solidarity finance. They also show the significant growth of local consumption, mostly through the use of the Palmas social currency. The Banco Palmas experience, aside from influencing national public policies of solidarity finance, initiated a CDBs network that encourages the replication of these experiences throughout the country.

  1. Stability analysis of Western flank of Cumbre Vieja volcano (La Palma) using numerical modelling

    La Palma volcanic island is one of the youngest of the Canary archipelago, being a composite volcano formed by three overlapping volcanic centers. There are clear onshore and offshore evidences of past giant landslides that have occurred during its evolution. Currently, the active Cumbre Vieja volcano is in an early development state (Carracedo et al., 2001). The study of flank instability processes aim to assess, among other hazards, catastrophic collapse and potential tsunami generation. Early studies of the potential instability of Cumbre Vieja volcano western flank have focused on the use of sparse geodetic networks (Moss et al. 1999), surface geological mapping techniques (Day et al. 1999) and offshore bathymetry (Urgeles et al. 1999). Recently, a dense GNSS network and satellite radar interferometry results indicate ground motion consistent with deep-seated creeping processes (Prieto et al. 2009, Gonzalez et al. 2010). In this work, we present a geomechanical advanced numerical model that captures the ongoing deformation processes at Cumbre Vieja. We choose the Finite Elements Method (FEM) which is based in continuum mechanics and is the most used for geotechnical applications. FEM has the ability of using arbitrary geometry, heterogeneities, irregular boundaries and different constitutive models representative of the geotechnical units involved. Our main contribution is the introduction of an inverse approach to constrain the geomechanical parameters using satellite radar interferometry displacements. This is the first application of such approach on a large volcano flank study. We suggest that the use of surface displacements and inverse methods to rigorously constrain the geomechanical model parameter space is a powerful tool to understand volcano flank instability. A particular important result of the studied case is the estimation of displaced rock volume, which is a parameter of critical importance for simulations of Cumbre Vieja tsunamigenic hazard

    Full Text Available La pudrición del cogollo (PC es la principal enfermedad de la palma en Colombia. En las zonas palmeras Central (ZC y Oriental (ZE, las palmas enfermas pueden recuperarse naturalmente. En la Zona Occidental (ZW el proceso de recuperación no es evidente. La recuperación de palmas está ligada a gran actividad meristemática que podría involucrar la acción inductora de metabolitos como las poliaminas (PA. Este trabajo muestra la relación entre poliaminas del meristemo y la capacidad de recuperación de palmas con PC, en dos zonas agroclimáticas diferentes. Poliaminas extraídas del meristemo de palmas sembradas en ZC y ZW, fueron analizadas por HPLC. En ZC, donde existe recuperación espontánea, los niveles más altos de PA se presentan en palmas sanas y en recuperación y a medida que avanza la enfermedad la concentración desciende hasta un mínimo en el estado de PC inicial (PCI. Luego la concentración de PA aumenta hasta el estado de Buena Recuperación (BR donde los valores de poliaminas son más altos que los de palmas sanas. En la ZW, con la enfermedad el contenido de PA aumenta llegando al máximo en plantas sin recuperación y el mínimo se presenta en plantas sanas. Las diferencias entre zonas pueden explicarse por diferentes roles de las poliaminas en plantas. En la ZC la cantidad elevada de PA en palmas sanas o en recuperación funcionaría en la inducción de actividad meristemática, para la recuperación espontánea. En la ZW el aumento en el contenido de PA con la enfermedad induciría la generación de especies reactivas de oxígeno para defensa secundaria de la planta ante la imposibilidad de, a través de incrementos en la actividad meristemática producir rápidamente estructuras sanas que no sean reinfectadas.

    Janisch, Astrid; Ntaflos, Theodoros

    2015-04-01

    La Palma is the second youngest island, after El Hierro, of the Canary archipelago. The archipelago consists of seven large islands, forming an east-west-trending island chain, and several seamounts. All together they form a volcanic belt of around 800 km length and 450 km width, which presumably comprises roughly the Canary hotspot. The islands are located off the western coast of Morocco, Africa. The distance ranges from 100 km to 500 km. Concurrently with the distance, subaerial volcanism age progresses from the oldest lava in the east to the youngest in the west of the archipelago. Presently, La Palma is in the shield building stage of growth (alongside with El Hierro and Tenerife) and is furthermore the fastest growing island of the Canary archipelago. Historical volcanic eruptions are restricted on the younger islands, La Palma and El Hierro, with the last eruption at the south end of La Palma in 1971. Mantle xenoliths described in this work were collected at the slopes of San Antonio Volcano, Fuencaliente, brought to the surface during the 1677/1678 eruption. The mantle xenolith collection comprises sp-lherzolites, sp-harzburgites and pyroxenites. The texture can be distinguished between coarse-grained matrix and fine-grained veins in various thicknesses, mostly with olivine and pyroxene but also with amphibole, phlogopite as well as apatite. Mineral analyses reveal the existence of primary and secondary ol, cpx and opx. Primary ol has Fo contents of 89.2 to 91.7 and NiO ranging from 0.3 to 0.45 wt.%, whereas secondary ol show Fo values of 78.4 to 91.9 but with NiO below 0.3 wt.%. Primary cpx are predominantly Cr-Diopsides with En48.7-51.9-Wo43.5-44.3-Fs4.1-4.9 and Mg# of 91.5 to 92.4. Secondary cpx, primarily Ti-Augit, display En36.7-44.4-Wo47.7-49.6-Fs6.7-13.0 and Mg# of 75.3 to 90.8. Primary opx compositions are in range of En89.3-90.6-Wo1.3-1.5-Fs8.1-9.3 with Mg# between 90.7 and 92.0. Secondary opx exhibit En88.7-89.2-Wo1.7-1.9-Fs9.1-9.5 and Mg# of 90

    Teachers are at great risk of physical and mental stress due to material or psychological difficulties associated with their work. This study aimed to assess the prevalence of common psychiatric symptoms measured on the Self-Reporting Questionnaire (SRQ-20) scale that would suggest a diagnosis of psychiatric disorders among public school teachers in Palmas, Tocantins, Brazil, in 2012. Observational cross-sectional study in Palmas, Tocantins, Brazil. We assessed 110 municipal teachers in the city of Palmas, Tocantins, Brazil. They were selected randomly from a list of employees of the Municipal Education Department of Palmas. All of them answered the SRQ-20 questionnaire after giving their consent. Between the years 2008 and 2011, 24 cases of absence from work due to mental disorders were found. We excluded one case and 109 teachers answered the SRQ-20questionnaire. Out of the 109 teachers assessed, 54 had ≥ 7 points on the SRQ-20 scale. This finding suggests that 49.5% of the teachers had symptoms that were sufficient to consider a diagnosis of mental disorder, with the need for treatment. Our study found that the prevalence of mental disorders among teachers is as high as seen in the literature. Our results suggest that recognition of mental disorders is low and that the current statistics fail to reach the occupational health sector.

    2015-06-01

    Full Text Available In the first decades of the twentieth century Palma emerged as a city worth visiting with a promising network of hotels and organised tours. Palma became an urban playground for British bohemians, artists, expatriates, and socialites. Their notion of leisure and pleasure (on a faraway island provided the leitmotiv for the years to come. The purpose of this paper is to inspect the extent of which the different discourses adopted by British travel writers in the beginning of the twentieth century (coinciding with the birth of modern tourism on the island worked to conform a contemporary vision of Palma and its coastal suburban areas (such as Magaluf or El Arenal as opposed to the (rural and allegedly ‘authentic’ island. Firstly, the paper examines the different stages through which both Palma and the island are discursively constructed as opposed entities in the travel accounts in Mallorca’s first stages of tourism. A special focus is given to the discursive and ideological tools deployed to embellish upon or belittle the city and the island. Finally, I suggest that the images proposed by travellers in their accounts a hundred years ago evolve in today’s imagotypes of the island and its city.

Apesar de sua magnitude para a agropecuária, seu cultivo tem dispensando tratos culturais básicos e embasamento técnico-científico quanto às suas exigências climáticas. Assim, o principal objetivo deste estudo foi elaborar o zoneamento agroclimático da cultura da palma forrageira (Opuntia sp. para o estado da Paraíba. O zoneamento agroclimático da palma forrageira foi elaborado com base nos indicadores climáticos delineados na literatura e nos dados climatológicos de precipitação e temperatura (média, máxima e mínima de 97 localidades do estado da Paraíba. De acordo com os resultados obtidos, a mesorregião da Borborema é a que apresenta as condições climáticas mais favoráveis para o cultivo da palma forrageira. As mesorregiões do Agreste, Sertão e a parte do Litoral, são aptas porém com restrições. No entanto, recomenda-se o cultivo da palma forrageira em todo o território do estado da Paraíba, exceto para a parte costeira da mesorregião do Litoral e região em torno de Areia. Em ambos os casos a inaptidão ocorre em função do excesso de precipitação.

    In the current study, the analgesic and free radical scavenging properties of an aqueous extract from the husk fiber of Cocos nucifera L. (Palmae) were demonstrated by the use of in vivo and in vitro models. The orally administered Cocos nucifera aqueous extract (200 or 400 mg/kg) inhibited the acetic acid-induced writhing response in mice. Tail flick and hot plate assays demonstrated that treatment of animals with this plant extract at 200 mg/kg induced attenuation in the response to a heat stimulus. A LD(50) of 2.30 g/kg was obtained in acute toxicity tests. Topic treatment of rabbits with the Cocos nucifera extract indicated that it does not induce any significant dermic or ocular irritation. In vitro experiments using the 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) photometric assay demonstrated that this plant extract also possesses free radical scavenging properties.

    Full Text Available The southern region of Paraná State is considered to be a priority area for mammal research in the state. This work aimed to present an inventory of the mammal species occurring in the locality known as Campos de Palmas, Paraná, Southern Brazil (26º34’59”S and 51º36’16”W, and to promote discussion about their importance for regional conservation. This assessment was carried out in two field stages, totaling 15 days. Thirty-five mammal species were recorded by direct observation, capture with mist nets, presence of feces and tracks, and identification of animals killed on the BR-280 highway. This inventory registered endangered species for Paraná and Brazil, as well as other important records of some mammal species at regional and national level.

    Full Text Available The practice of sustainable transport planning must take into account the level of territorial and social equity of service. The equity analysis requires a deep understanding of the service and the territorial and social characteristics where it is implanted. We propose a simplified method to analyze the equity of the public bus system that has been used in the city of Palma de Mallorca. The bus service level was calculated from the spatial analysis of the offer and was contrasted with the population and with a multidimensional index of social need for public transportation leading to horizontal and vertical equity respectively. Next the overall equity of the service was tested with the support of the Lorenz curve and Gini coefficient. Finally, a sensitivity analysis of bus routes depending on the role they play in the equity of the service was performed.

    Grazing management is probably one of the most extensive land uses, but its effects on plant communities have in many cases been revealed to be contradictory. Some authors have related these contradictions to the stochastic character of grazing systems. Because of that, it is necessary to implement specific analyses of grazing effects on each community, especially in natural protected areas, in order to provide the best information to managers. We studied the effects of grazing on the species composition of the main vegetation types where it takes place (grasslands, shrublands and pine forests) on the island of La Palma, Canary Islands. We used the point-quadrat intersect method to study the species composition of grazed and ungrazed areas, which also were characterized by their altitude, distance to farms, distance to settlements, year of sampling, herbaceous aboveground biomass and soil organic matter. The variables organic matter, productivity and species richness were not significantly affected by grazing. The species composition of the analyzed plant communities was affected more by variables such as altitude or distance to farms than by extensive grazing that has been traditionally carried out on the island of La Palma involving certain practices such as continuous monitoring of animals by goat keepers, medium stocking rates adjusted to the availability of natural pastures, supplementation during the dry season using local forage shrubs or mown pastures and rotating animals within grazing areas Although some studies have shown a negative effect of grazing on endangered plant species, these results cannot be freely extrapolated to the traditional grazing systems that exert a low pressure on plant communities (as has been found in this study). We consider extensive grazing as a viable way of ensuring sustainable management of the studied ecosystems.

    Full Text Available We compare past and present systems of management of palms in the Colombian Amazon, based on archaeological studies of preceramic groups in the middle Caquetá region and ethnographic research on the nomadic Nukak people, who inhabit northeastern Guaviare department. Astrocaryum aculeatum, Attalea maripe, Mauritia flexuosa, Oenocarpus bataua, Oenocarpus bacaba y Oenocarpus mapora, have been used from the early Holocene through the present time. Among these, Oenocarpus bataua has remained the most important food species. We conclude that one of the mananging strategies of the tropical rain forest is the simultaneous improvement of ecological units, especially in the tertiary sedimentary plains, and that such management probably has a long history in the region.Se presenta una comparación sobre el manejo de las palmas en la Amazonia Colombiana, basado en los resultados de un estudio arqueológico de grupos precerámicos en la región del Medio Caquetá y uno etnográfico del pueblo nómada Nukak que habita la zona nororiental del departamento del Guaviare. Se encontró que Astrocaryum aculeatum, A ttalea maripa, Mauritia flexuosa, Oenocarpus bataua, Oenocarpus bacaba y Oenocarpus mapora son algunas de las palmas usadas desde el Holoceno temprano hasta el presente. Entre estas Oenocarpus bataua es la especie más importante como fuente de alimento. Así mismo, se concluye que una de las estrategias de manejo en el bosque húmedo tropical es el aprovechamiento simultáneo de diferentes unidades ecológicas, con predominio del plano sedimentario terciario. Es probable que este tipo de manejo tenga en la región una larga historia.

    A field experiment was conducted under saline conditions (soil EC e 15, water EC w 8 dS/m/m) to evaluate the performance of sole crops and inter crops of Sesbania aculeata and Sorghum bicolor (1:1 row ratio) in terms of dry matter production, total N yield, soil N uptake and N 2 -fixation using 15 N isotope dilution method. Dry matter yield in sole crop of sesbania was significantly higher that that of sole sorghum; whereas, that of the inter cropping was significantly lower than sole sesbania, but was similar to that produced by sole sorghum. Total nitrogen yield in sole sesbania was four-fold than that accumulated in sole sorghum, whereas, that of mixed cropping was 2.6 fold compared to that of sole sorghum. The LER of total N yield was higher than 1 reflecting a greater advantage of inter cropping system in terms of land use efficiency. The proportion of N derived from N 2 fixation (%Ndfa) in the sesbania was increased from 63 to 79%, for sole and inter cropping system, respectively. There was no evidence of a significant transfer of N from the sesbania to the sorghum. Results on the relative growth of plants on saline soil compared with non-saline soil clearly demonstrated that sesbania was more salt tolerant than the sorghum. soil nitrogen uptake by plants, particularly in sorghum, was adversely affected by salinity. However, amounts of N 2 fixed by sole sesbania grown is saline soil was close or even higher than on non-saline soil. The use of inter cropping systems of legumes and non-legumes could be a promising agricultural approach to reutilize wasted lands, after a careful selection of appropriate tolerant genotypes to prevailing saline conditions.

    A field experiment on Sesbania aculeata and Sorghum bicolor grown in mono cropping and in inter cropping systems was conducted under non-saline conditions (soil EC e 0.16, water EC w 1dS/m) to evaluate dry matter production, total N yield, soil N uptake and N 2 -fixation using 15 N isotope dilution method. Three different row ratios of sesbania (ses) and sorghum (sor) were subjected in the inter cropping system (2ses: 1sot; 1ses: 1sor and 1ses: 2sor row ratio). Dry matter yield of sole sorghum was higher than that of sole sesbania, and it was similar to that produced by the inter cropping treatments. However, total N yield of sole sorghum was significantly the lowest, with no differences being obtained between sole sesbania and inter cropping treatments. The LERs of total N yield were, in all cases, higher than 1, reflecting a greater advantage of inter cropping system in terms of land use efficiency. Percentages of N 2 fixation in the inter cropped sesbania were considerably enhanced compared with the pure stand of sesbania. This was mainly attributed to the depletion of soil N resulting from the greater apparent competitiveness of sorghum for soil N, and consequently, a greater dependence of sesbania on N 2 fixation. However, the degree of the intraspecific competition for soil N uptake was affected by the proportion of crops in the mixture, and it was considerably reduced in the 2ses: 1sor row ratio. This was demonstrated when an equal depletion of soil and fertilizer N uptake occurred for both crops. We excluded in all-inter cropping treatments the possibility of N transfer from sesbania to sorghum. Row inter cropping, with crops grown in alternation of two rows of sesbania with one row of sorghum, seemed to be the most adequate row ratio in terms of total N yield, LER, N 2 -fixation and soil N uptake balance of the component crops.

    The ability of aculeate Hymenoptera to utilize wetlands is poorly understood, and descriptions of their nests and developmental stages are largely absent. Here we present results based on our survey of hymenopterans using galls induced by Lipara spp. flies on common reed Phragmites australis in the years 2015-2016. We studied 20,704 galls, of which 9,446 were longitudinally cut and the brood from them reared in the laboratory, while the remaining 11,258 galls reared in rearing bags also in laboratory conditions. We recorded eight species that were previously not known to nest in reed galls: cuckoo wasps Chrysis rutilans and Trichrysis pumilionis, solitary wasps Stenodynerus chevrieranus and Stenodynerus clypeopictus, and bees Pseudoanthidium tenellum, Stelis punctulatissima, Hylaeus communis and Hylaeus confusus. Forty five species of Hymenoptera: Aculeata are known to be associated with reed galls, of which 36 make their nests there, and the other are six parasitoids of the family Chrysididae and three cuckoo bees of the genus Stelis. Of these species, Pemphredon fabricii and in southern Europe also Heriades rubicola are very common in reed galls, followed by Hylaeus pectoralis and two species of the genus Trypoxylon. We also found new host-parasite associations: Chrysis angustula in nests of Pemphredon fabricii, Chrysis rutilans in nests of Stenodynerus clypeopictus, Trichrysis pumilionis in nests of Trypoxylon deceptorium, and Stelis breviuscula in nests of Heriades rubicola. We provide new descriptions of the nests of seven species nesting in reed galls and morphology of mature larvae of eight species nesting in reed galls and two parasitoids and one nest cleptoparasite. The larvae are usually very similar to those of related species but possess characteristics that make them easy to distinguish from related species. Our results show that common reeds are not only expansive and harmful, but very important for many insect species associated with habitats

    The island factor in the cities of Las Palmas de Gran Canaria and Santa Cruz de Tenerife, their meteorology and the proximity to the African Continent that originates the natural particulate matter transport over the islands, cause some specific features in their air quality. The aim of this paper is to characterize the air pollution from 2000 to 2004 as exposure indicator of both cities inhabitants. 24 hour daily average variables of PM10, PM2,5, NO2, SO2 and O3 , 8 hours daily maxima moving averages of O3 y CO and 1 hour maxima of SO2, NO2, O3, CO, PM10 y PM2,5 were calculated. Daily levels of coarse particles were obtained subtracting PM2,5 from PM10. African dust events were identified. In Sta. Cruz de Tf daily means of SO2 (14.0 microg/m(3)N) and ozone levels (44.4 microg/m(3)N ) were higher than Las Palmas de GC levels (8.0 y 28.3 microg/m(3)N). Daily means of NO2 in Las Palmas de GC: 45.8 microg/m(3)N where higher than Sta. Cruz de Tf levels: 30.3 microg/m(3)N. Due to African dust outbreaks, some days in both cities exceeded 600 microg/m(3) of PM10 and 200 of PM2.5 24-h average. The air quality patterns were characterized by very high levels of African dust outbreaks that affect all PM size fractions. Different O3 seasonality exists respect European cities in addition to an urban-industrial ambient air in Sta. Cruz de TF and clearly urban in Las Palmas de GC. These results have to be considered in order to lay the foundations to suitable surveillance systems, analyse the potential impact on the Canary Islands citizens health and to get conclusions.

    A field study was performed to evaluate the effect of exposure to organophosphorus (OP) and carbamate (CB) pesticides on the lizard Gallotia galloti palmae. Butyrylcholinesterase (BChE) activity was measured in the plasma of 420 lizards collected from agricultural and reference areas on the Island of La Palma (Canary Islands, Spain) in two sampling periods. Exposure to cholinesterase-inhibiting pesticides was evaluated by a statistical criterion based on a threshold value (two standard deviations below the mean enzyme activity) calculated for the reference group, and a chemical criterion based on the in vitro reactivation of BChE activity using pyridine-2-aldoxime methochloride (2-PAM) or after water dilution of the sample. Mean (±SD) BChE activity for lizards from agricultural areas was significantly lower (Fuencaliente site = 2.00 ± 0.98 μmol min -1 ml -1 , Tazacorte site = 2.88 ± 1.08) than that for lizards from the reference areas (Los Llanos site = 3.06 ± 1.17 μmol min -1 ml -1 , Tigalate site = 3.96 ± 1.62). According to the statistical criterion, the number of lizards with BChE depressed was higher at Fuencaliente (22% of males and 25.4% of females) than that sampled at Tazacorte (7.8% of males and 6.2% of females). According to the chemical criterion, Fuencaliente also yielded a higher number of individuals (112 males and 47 females) with BChE activity inhibited by both OP and CB pesticides. CBs appeared to be the pesticides most responsible for BChE inhibition because most of the samples showed reactivation of BChE activity after water treatment (63.3% from Fuencaliente and 29% from Tazacorte). We concluded that the use of reactivation techniques on plasma BChE activity is a better and more accurate method for assessing field exposure to OP/CB pesticides in this lizard species than making direct comparisons of enzyme activity levels between sampling areas. - Capsule: Chemical reactivation of lizard BChE activity is a suitable diagnostic method for

    We report herein the results of 13 soil CO2 efflux surveys at Cumbre Vieja volcano, La Palma Island, the most active basaltic volcano in the Canary Islands. The CO2 efflux measurements were undertaken using the accumulation chamber method between 2001 and 2013 to constrain the total CO2 output from the studied area and to evaluate occasional CO2 efflux surveys as a volcanic surveillance tool for Cumbre Vieja. Soil CO2 efflux values ranged from non-detectable up to 2442 g m-2 days-1, with the highest values observed in the south, where the last volcanic eruption took place (Teneguía, 1971). Isotopic analyses of soil gas carbon dioxide suggest an organic origin as the main contribution to the CO2 efflux, with a very small magmatic gas component observed at the southern part of the volcano. Total biogenic and magmatic combined CO2 emission rates showed a high temporal variability, ranging between 320 and 1544 t days-1 and averaging 1147 t days-1 over the 220-km2 region. Two significant increases in the CO2 emission observed in 2011 and 2013 were likely caused by an enhanced magmatic endogenous contribution revealed by significant changes in the 3He/4He ratio in a CO2-rich cold spring. The relatively stable emission rate presented in this work defines the background CO2 emission range for Cumbre Vieja during a volcanic quiescence period.

    The available therapy for leishmaniasis, which affects 2 million people per annum, still causes serious side effects. The polyphenolic-rich extract from the husk fiber of Cocos nucifera Linn. (Palmae) presents antibacterial and antiviral activities, also inhibiting lymphocyte proliferation, as shown by our group in previous works. In the present study, the in vitro leishmanicidal effects of C. nucifera on Leishmania amazonensis were evaluated. The minimal inhibitory concentration of the polyphenolic-rich extract from C. nucifera to completely abrogate parasite growth was 10 microg/ml. Pretreatment of peritoneal mouse macrophages with 10 microg/ml of C. nucifera polyphenolic-rich extract reduced approximately 44% the association index between these macrophages and L. amazonensis promastigotes, with a concomitant increase of 182% in nitric oxide production by the infected macrophage in comparison to nontreated macrophages. These results provide new perspectives on drug development against leishmaniasis, since the extract of C. nucifera at 10 microg/ml is a strikingly potent leishmanicidal substance which inhibited the growth of both promastigote and amastigote developmental stages of L. amazonensis after 60 min, presenting no in vivo allergenic reactions or in vitro cytotoxic effects in mammalian systems.

    A field experiment on Sesbania aculeata and Sorghum bicolor grown in mono cropping and in inter cropping systems was conducted under non-saline conditions (soil EC{sub e} 0.16, water EC{sub w}1dS/m) to evaluate dry matter production, total N yield, soil N uptake and N{sub 2}-fixation using {sup 15}N isotope dilution method. Three different row ratios of sesbania (ses) and sorghum (sor) were subjected in the inter cropping system (2ses: 1sot; 1ses: 1sor and 1ses: 2sor row ratio). Dry matter yield of sole sorghum was higher than that of sole sesbania, and it was similar to that produced by the inter cropping treatments. However, total N yield of sole sorghum was significantly the lowest, with no differences being obtained between sole sesbania and inter cropping treatments. The LERs of total N yield were, in all cases, higher than 1, reflecting a greater advantage of inter cropping system in terms of land use efficiency. Percentages of N{sub 2} fixation in the inter cropped sesbania were considerably enhanced compared with the pure stand of sesbania. This was mainly attributed to the depletion of soil N resulting from the greater apparent competitiveness of sorghum for soil N, and consequently, a greater dependence of sesbania on N{sub 2} fixation. However, the degree of the intraspecific competition for soil N uptake was affected by the proportion of crops in the mixture, and it was considerably reduced in the 2ses: 1sor row ratio. This was demonstrated when an equal depletion of soil and fertilizer N uptake occurred for both crops. We excluded in all-inter cropping treatments the possibility of N transfer from sesbania to sorghum. Row inter cropping, with crops grown in alternation of two rows of sesbania with one row of sorghum, seemed to be the most adequate row ratio in terms of total N yield, LER, N{sub 2}-fixation and soil N uptake balance of the component crops.

    The analysis of circadian leaf movement rhythms is a simple yet effective method to study effects of treatments or gene mutations on the circadian clock of plants. Currently, leaf movements are analysed using time lapse photography and subsequent bioinformatics analyses of leaf movements. Programs that are used for this purpose either are able to perform one function (i.e. leaf tip detection or rhythm analysis) or their function is limited to specific computational environments. We developed a leaf movement analysis tool-PALMA-that works in command line and combines image extraction with rhythm analysis using Fast Fourier transformation and non-linear least squares fitting. We validated PALMA in both simulated time series and in experiments using the known short period mutant sensitivity to red light reduced 1 ( srr1 - 1 ). We compared PALMA with two established leaf movement analysis tools and found it to perform equally well. Finally, we tested the effect of reduced iron conditions on the leaf movement rhythms of wild type plants. Here, we found that PALMA successfully detected period lengthening under reduced iron conditions. PALMA correctly estimated the period of both simulated and real-life leaf movement experiments. As a platform-independent console-program that unites both functions needed for the analysis of circadian leaf movements it is a valid alternative to existing leaf movement analysis tools.

    Full Text Available The aim of this study was to analyze the distribution and abundance of the fish fauna of Palmas bay on Anchieta Island in southeastern Brazil. Specimens were caught in the summer and winter of 1992, using an otter trawl at three locations in the bay. The specimens were caught in both the nighttime and daytime. Data on the water temperature and salinity were recorded for the characterization of the predominant water mass in the region, and sediment samples were taken for granulometric analysis. A total of 7 656 specimens (79 species, with a total weight of approximately 300 kg, were recorded. The most abundant species were Eucinostomus argenteus, Ctenosciaena gracilicirrhus, Haemulon steindachneri, Eucinostomus gula and Diapterus rhombeus, which together accounted for more than 73% of the sample. In general, the ecological indices showed no differences in the composition of species for the abiotic variables analyzed. The multivariate analysis showed that the variations in the distribution of the fish fauna were mainly associated with intra-annual differences in temperature and salinity, resulting from the presence of South Atlantic Central Water (SACW in the area during the summer. The analysis also showed an association with the type of bottom and a lesser association with respect to the night/day periods.Este estudo teve como objetivo analisar a composição e a abundância da fauna de peixes provenientes da enseada Palmas em Ubatuba, costa sudeste do Brasil.

    In the present study, we investigated the in vitro anti-tumoral activities of fractions from aqueous extracts of the husk fiber of the typical A and common varieties of Cocos nucifera (Palmae). Cytotoxicity against leukemia cells was determined by the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide (MTT) assay. Cells (2 x 10(4)/well) were incubated with 0, 5, 50 or 500 microg/mL high- or low-molecular weight fractions for 48 h, treated with MTT and absorbance was measured with an ELISA reader. The results showed that both varieties have almost similar antitumoral activity against the leukemia cell line K562 (60.1 +/- 8.5 and 47.5 +/- 11.9% for the typical A and common varieties, respectively). Separation of the crude extracts with Amicon membranes yielded fractions with molecular weights ranging in size from 1-3 kDa (fraction A) to 3-10 kDa (fraction B) and to more than 10 kDa (fraction C). Cells were treated with 500 microg/mL of these fractions and cytotoxicity was evaluated by MTT. Fractions ranging in molecular weight from 1-10 kDa had higher cytotoxicity. Interestingly, C. nucifera extracts were also active against Lucena 1, a multidrug-resistant leukemia cell line. Their cytotoxicity against this cell line was about 50% (51.9 +/- 3.2 and 56.3 +/- 2.9 for varieties typical A and common, respectively). Since the common C. nucifera variety is extensively cultured in Brazil and the husk fiber is its industrial by-product, the results obtained in the present study suggest that it might be a very inexpensive source of new antineoplastic and anti-multidrug resistant drugs that warrants further investigation.

    In 1949, a 5-week-long magmatic and phreatomagmatic eruption took place along the active volcanic ridge of La Palma (Canary Islands). Two vents, Duraznero and Hoyo Negro, produced significant pyroclastic deposits. The eruption began from Duraznero vent, which produced a series of deposits with an upward decrease in accidental fragments and increase in fluidal ash and spatter, together inferred to indicate decreasing phreatomagmatic interaction. Hoyo Negro erupted over a 2-week period, producing a variety of pyroclastic density currents and ballistic blocks and bombs. Hoyo Negro erupted within and modified an older crater having high walls on the northern to southeastern edges. Southwestern to western margins of the crater lay 50 to 100 m lower. Strongly contrasting deposits in the different sectors (N-SE vs. SW-W) were formed as a result of interaction between topography, weak eruptive columns and stratified pyroclastic density currents. Tephra ring deposits are thicker and coarser-grained than upper rim deposits formed along the higher edges of the crater, and beyond the crater margin, valley-confined deposits are thicker than more thinly bedded mantling deposits on higher topography. These differences indicate that the impact zone for the bulk of the collapsing, tephra-laden column lay within the crater and that the high crater walls inhibited escape of pyroclastic density currents to the north and east. The impact zone lay outside the low SW-W rims, however, thus allowing stratified pyroclastic density currents to move freely away from the crater in those directions, depositing thin sections (<30 cm) of well-bedded ash (mantling deposits) on ridges and thicker sections (1-3 m) of structureless ash beds in valleys and small basins. Such segregation of dense pyroclastic currents from more dilute ones at the crater wall is likely to be common for small eruptions from pre-existing craters and is an important factor to be taken into account in volcanic hazards

    Actinomycete strain CMU-AB204T was isolated from oil palm rhizosphere soil collected in Chiang Mai University (Chiang Mai, Thailand). Based on morphological and chemotaxonomic characteristics, the organism was considered to belong to the genus Streptomyces. Whole cell-wall hydrolysates consisted of ll-diaminopimelic acid, glucose, ribose and galactose. The predominant menaquinones were MK-9(H4), MK-9(H6), MK-9(H2) and MK-8(H4). The fatty acid profile contained iso-C15 : 0, iso-C16 : 0 and anteiso-C15 : 0 as major components. The principal phospholipids detected were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylglycerol. The DNA G+C content of strain CMU-AB204T was 70.9 mol%. Based on 16S rRNA gene sequence similarity, strain CMU-AB204T was closely related to Streptomyces orinoci JCM 4546T (98.7 %), Streptomyces lilacinus NBRC 12884T (98.5 %), Streptomyces abikoensis CGMCC 4.1662T (98.5 %), Streptomyces griseocarneus JCM 4905T (98.4 %) and Streptomyces xinghaiensis JCM 16958T (98.3 %). Phylogenetic trees revealed that the new strain had a distinct taxonomic position from closely related type strains of the genus Streptomyces. Spiny to hairy spores clearly differentiated strain CMU-AB204T from the five most closely related Streptomyces species, which produced smooth spores. On the basis of evidence from this polyphasic study, it is proposed that strain CMU-AB204T represents a novel species of the genus Streptomyces, namely Streptomyces palmae sp. nov. The type strain is CMU-AB204T (=JCM 31289T=TBRC 1999T).

    Full Text Available Abstract Background The amphipod crustacean Palmorchestia hypogaea occurs only in La Palma (Canary Islands and is one of the few terrestrial amphipods in the world that have adapted to a strictly troglobitic life in volcanic cave habitats. A surface-dwelling closely related species (Palmorchestia epigaea lives in the humid laurel forest on the same island. Previous studies have suggested that an ancestral littoral Orchestia species colonized the humid forests of La Palma and that subsequent drought episodes in the Canaries reduced the distribution of P. epigaea favouring the colonization of lava tubes through an adaptive shift. This was followed by dispersal via the hypogean crevicular system. Results P. hypogaea and P. epigaea did not form reciprocally monophyletic mitochondrial DNA clades. They showed geographically highly structured and genetically divergent populations with current gene flow limited to geographically close surface locations. Coalescence times using Bayesian estimations assuming a non-correlated relaxed clock with a normal prior distribution of the age of La Palma, together with the lack of association of habitat type with ancestral and recent haplotypes, suggest that their adaptation to cave life is relatively ancient. Conclusion The data gathered here provide evidence for multiple invasions of the volcanic cave systems that have acted as refuges. A re-evaluation of the taxonomic status of the extant species of Palmorchestia is needed, as the division of the two species by habitat and ecology is unnatural. The information obtained here, and that from previous studies on hypogean fauna, shows the importance of factors such as the uncoupling of morphological and genetic evolution, the role of climatic change and regressive evolution as key processes in leading to subterranean biodiversity.

    Determining the link between shallow structure and volcanism is a topic of interest in Volcanology. We carried out a geophysical study devoted to the characterization of the major structural limits influencing volcanic hydrothermal activity and underground meteoric circulations in La Palma (Canary Islands). Since 1 Ma volcanic activity concentrates at the southern half of the island, on the Cumbre Vieja volcanic rift-zone. During the 1949 eruption a N-S fault system, facing west, developed in the summit area of Cumbre Vieja. This was interpreted as the surface expression of an incipient deformation zone on the western flank. The distribution of the recent activity and faulting indicate that a discontinuity may be present beneath the western flank of Cumbre Vieja, along which a future collapse may occur. Our study, which combines the application of self-potential and soil temperature measurements, provides new information to characterize and locate the limits guiding upward or downward fluid circulation and possibly associated to future failures and potential landslides on the Cumbre Vieja rift-zone. We found a clear asymmetry of the self-potential signal between the eastern and the western flanks of Cumbre Vieja. Strong infiltration of meteoric water seems to affect most of the summit axis while we observe poor variation in the self-potential values on the western flank. This could be explained by a constant thickness of the vadose zone on this flank, i.e., the presence of an impermeable layer at constant depth. This layer could correspond to the landslide interface associated to the previous Cumbre Nueva edifice destruction, on which Cumbre Vieja is currently growing. This constant self-potential pattern is interrupted by at least one other main infiltration zone, near Tajuya volcano, at 1200 m a.s.l. on the western flank, where field observation allowed identifying a small horst-graben system. However it is not clear if this fault system results from local

  17. Insular identity and urban contexts: representations of the local in the construction of an image of Palma (Mallorca, Balearic Islands

    Mercè Picornell

    2014-11-01

    Full Text Available This article analyses the relationship between island and city in the configuration of an insular identity. The hypothesis addresses the special visibility that, in the case of small islands, results from the confrontation between two relevant singularities – the city and the island – in the symbolic conceptualization of territory. The opposition between island contexts and urban spaces is thus considered in terms of the local/global and rural/urban binaries. These are analysed in contemporary cultural representations of the relationship between the island of Mallorca and its historical and administrative capital, Palma. Since the 1960s, Mallorca has become a mass tourism destination with a considerable demographic impact, especially in the capital, which is the island’s gateway for both tourism and immigration. This paper considers geographical, literary and media discourses along with particular mass-consumption cultural products to argue that Palma is represented as a predatory ‘monster’ devouring the island’s ‘local’ identity. It is argued that different types of neo-ruralism have emerged and reinforced the opposition between the island and the city. This opposition underlies a process of counter-acculturation that delineates and strengthens Mallorcan self-representation in a context defined by an increasingly diverse population as a result of tourism and migratory flows.

Su localización está controlada fundamentalmente por la densidad edificatoria y la intensidad del tráfico. El Istmo de la Isleta se comporta como una isla de frescor.In this article, we present the outlines of the thermal behaviour of the city of Las Palmas de Gran Canaria. Using the method of travelling around the city, we recorded temperature and humidity data for 42 sites in the city, including different formal and functional areas. The results confirm that there is a bi-focal and moderate island of nocturnal heat, although it can reach 5.3ºC. This is determined fundamentally by building density and the intensity of the traffic. The Isthmus of La Isleta acts as an island of fresh temperatures.

    Full Text Available En el proceso de extracción de aceite de palma, se consideran alternativas de separación de los residuos sólidos y líquidos para el aprovechamiento (si es posible total del efluente. Estos residuos sólidos de naturaleza orgánica, y las descargas líquidas, suelen considerarse de bajo impacto en comparación con otros procesos productivos de algunos sectores industriales. En este sentido, la presente investigación tiene como propósito analizar el manejo de los efluentes en el proceso de extracción de aceite de palma o aceite rojo. Asimismo, se presenta la estrategia ambiental en este tipo de proceso utilizando la producción más limpia. La investigación es de tipo analítica, no experimental de campo; la población se delimitó a las empresas del sector de palma aceitera que desarrolla el proceso de extracción de aceite. Se realizaron varias visitas y entrevistas al personal de estas empresas; siendo necesario aclarar que para efectos de esta investigación, solamente se considera la producción de aceite rojo, en virtud de que del proceso de producción se obtienen dos sub productos, aceite de palmiste y harina de palmiste. Los resultados, indican que existen efluentes en las diferentes etapas del proceso de extracción de aceite, los cuales reciben un tratamiento especial, por lo que requieren de áreas que desempeñan actividades de apoyo, tales como: control de calidad, mantenimiento y generación de energía, las cuales intervienen en la generación y tratamiento de los efluentes. Se concluye que las empresas que utilizan este tipo de proceso productivo, emplean estrategias innovadoras para disminuir el impacto ambiental, en aras de mejorar el desempeño ambiental en este tipo de organización.

    Helium is considered as an ideal geochemical tracer due to its geochemical properties: chemical inertness, physical stability and practical insolubility in water under normal conditions. These characteristics, together with its high mobility on the crust, make the presence of helium anomalies on the surface environment of a volcanic system to be related to deep fluid migration controlled by volcano-tectonic features, also providing valuable information about the location and characteristics of the gas source and the fracturing of the crust. The recent results reported by Padrón et al. (2013) clearly show importance of helium emission studies for the prediction of major volcanic events and the importance of continuous monitoring of this gas in active volcanic regions. La Palma Island (708.32 km2) is located at the northwestern end of the Canarian Archipelago. Subaerial volcanic activity on this island started ˜2.0 My ago and has taken place exclusively at the southern part in the last 123 ka. Cumbre Vieja volcano, the most active basaltic volcano of the Canary Islands, was built in this zone, including a main north-south rift area 20 km long and up to 1,950 m in elevation, with vents located also at the northwest and northeast. Padrón et al., (2012) showed that helium is mainly emitted along both N-S and N-W rift of Cumbre Vieja, being, therefore, zones of enhanced permeability for deep gas migration and preferential routes for degassing. This work represents a continuation of the results obtained by Padrón et al. (2012) until the year 2016. Each study covered the 220 km2 of Cumbre Vieja with an average of 570 homogenously distributed sampling points. At each sampling site, soil gas samples were collected at 40 cm depth by withdrawing the gas aliquots into 60 cc hypodermic syringes. He content in the soil gases was analyzed by means of quadrupole mass spectrometry (QMS). Atmospheric gas was used periodically to calibrate the instrument. To estimate the helium

  16. Estimates of matter yield and N-uptake in sorghum grown on saline and non-saline soils manured with dhaincha (sesbania aculeata) plant residues utilizing 15N tracer techniques

    Kurdali, F.

    2002-11-01

    Pot experiments were conducted to study the effect of manuring with three types of plant residues (roots, shoots or roots plus shoots) of Dhaincha (Sesbania aculeata Pers.) on the yield and N-uptake of Sorghum bicolor grown in saline and non-saline soils. For measuring various sources of N-uptake, two isotopic dilution techniques were utilized by adding to these soils either 15 N-labelled inorganic N-fertilizer (indirect method) or 15 N-labelled sesbania leaves (direct method). For the indirect method, both soils manured with each type of sesbania residue, received four split applications of 15 N-labelled ammonium sulphate. Results indicated that each type of sesbania residue, applied as a green manure, resulted in significant increases in both dry matter yield and N-uptake of sorghum as compared with the un manured control. Moreover, sesbania residues decreased the harmful effect of salinity on plant growth. Percentages of N derived from residues (%Ndfr) in sorghum grown in non saline soil ranged between 3.9 and 33%; whereas, in saline soil, the observed values ranged between 4.9 and 19.8%. N recoveries in sorghum grown in non saline soil were 61, 45 and 37% of the total amount contained in the sesbania root, shoot and root plus shoot; whereas, values in sorghum grown in saline soils were 48, 14,8 and 15.7%, respectively. The beneficial effects of sesbania residues have been attributed not only to the additional N availability to the plants, but also to its effects on the enhancement of soil N uptake. Percentages and amounts of Ndfr calculated using the indirect method were not significantly different from those obtained by the direct method indicating that the indirect method used herein is feasible and simple for measuring N release from organic residues. It is suggested that the use of Sesbania aculeata residues, particularly the shoots, as a green manure, can provide a substantial portion of total N in sorghum. Moreover, the use of sesbania green manure in

    Net CO/sub 2/ uptake over 24-hour periods was examined for the leaves and for the stems of 11 species of cacti representing all three subfamilies. For Pereskia aculeata, Pereskia grandifolia, and Maihuenia poeppigii (subfamily Pereskioideae), all the net shoot CO/sub 2/ uptake was by the leaves and during the daytime. In contrast, for the leafless species Carnegiea gigantea, Ferocactus acanthodes, Coryphantha vivipara, and Mammillaria dioica (subfamily Cactoideae), all the shoot net CO/sub 2/ uptake was by the stems and at night. Similarly, for leafless Opuntia ficus-indica (subfamily Opuntioideae), all net CO/sub 2/ uptake occurred at night. For leafy members of the Opuntioideae (Pereskiopsis porteri, Quiabentia chacoensis, Austrocylindropuntia subulata), at least 88% of the shoot CO/sub 2/ uptake over 24 hours was by the leaves and some CO/sub 2/ uptake occurred at night. Leaves responded to the instantaneous level of photosynthetically active radiation (PAR) during the daytime, as occurs for C/sub 3/ plants, whereas nocturnal CO/sub 2/ uptake by stems of O. ficus-indica and F. acanthodes responded to the total daily PAR, as occurs for Crassulacean acid metabolism (CAM) plants. Thus, under the well-watered conditions employed, the Pereskioideae behaved as C/sub 3/ plants, the Cactoideae behaved as CAM plants, and the Opuntioideae exhibited characteristics of both pathways.

    The energy issue follows the history of mankind and nowadays has triggered a multidisciplinary debate. Within this discussion, there is the main topic of this study: the focus on the high electric power consumption in public buildings. The approach is in consonance with the sustainability of architecture and the use of solar photovoltaic energy as a technological tool that brings into alliance the renewable alternative energy sources and the buildings which are connected to the urban electric power lines. This study aims to demystify the use of alternative energy sources in conjunction with the contemporary architectonic production. In the first part the sustainability, the world energy issue and the use of active solar systems in architecture were contextualized and then, the main objective was to measure an Integrated Photovoltaic System in a public building- the Court of Justice in Palmas, Tocantins. For that reason, it was necessary to evaluate the energy efficiency in the building and to achieve that objective the energy consumption in the so-called rush hours and the 19:00 to 21:00 period of time were considered. Subsequently, the study tested several possibilities of photovoltaic panels and analyzed which one had the best performance, according to the local characteristic such as: the solar orientation, the latitude, the monthly and annual solar radiation average. There has been done a simulation of an ideal photovoltaic solar system with the proper calculus of its productivity, in order to provide a compensation to the energy consumption of the building- or a part of it- through the use of the alternative energy source in question. The objective is to demystify the generation of electric power from the use of solar energy and thus evaluating the contribution of the system to the conventional electric energy. Finally, a partial economic analysis of the system was carried out, driving to characterize the contribution potential of the Integrated Photovoltaic

    Full Text Available This paper addresses the rainfall episodes occurred during spring-summer season 2009/2010 in Palmas (TO, and their impacts on its urban area, construction of which hardly exceeds recent 21 years in 2010. It also constitutes a preliminary analysis about the genesis of the rhythm and of the climate exceptionalities in the study area, since there are few studies of Geographical Climatology about the state of Tocantins. The main elements of the atmospheric circulation were identifi ed through rhythmic analysis, as well as the stormwater impacts were also listed and reported by a local daily newspaper. These impacts were focused on their spatial distribution, seeking to emphasize the elements of vulnerability of the affected spots, as well as the selectivity and news content. The results allowed to give an initial overview on the relation between the rainfall, the geographical and human activities in Palmas, revealing aspects of its urban planning and its vulnerability to climate exceptionalities.

    The level of the night-sky background light at La Palma and Namibia was determined, with emphasis on the wavelength region and solid angle coverage relevant for the operation of imaging atmospheric Cherenkov telescopes. The dependence of the night-sky background light both on celestial coordinates (alt,az) and on galactic coordinates (b,l) was measured, with an angular resolution of about 1 deg. Average light levels near the zenith are similar in both locations -2.2x10 12 -2.6x10 12 photons sr -1 s -1 m -2 for 300 nm<λ<650 nm. With increasing zenith angle the level of background light increases at La Palma, whereas a constant level is measured in Namibia. Near the center of the Milky Way, background light levels are increased by a factor up to 4 and more. Also the level of light backscattered from the ground has been studied

    Alpha-1-antitrypsin (AAT) deficiency is a genetic condition that arises from mutations in the SERPINA1 gene and predisposes to develop pulmonary emphysema and, less frequently, liver disease. Occasionally, new defective SERPINA1 alleles are detected as an outcome of targeted-screening programs or case-findings. This study began with a female patient showing bronchial hyperreactivity. Serum level and phenotype for AAT was analysed by immunonephelometry and isoelectric focusing electrophoresis. The SERPINA1 gene of the proband was genotyped by PCR amplification and DNA sequencing. Analysis of AAT deficiency was extended to the proband's family. An abnormal AAT variant that migrated to a more cathodal position than PiZ AAT was detected in the proband's serum. Genetic analysis demonstrated that proband is heterozygous for a new defective SERPINA1 allele (PI*Z la palma ) characterized by the c.321C > A (p.Asn83Lys) mutation in the M1Val213 background. This mutation abolishes the N-glycosylation site in position 83 of the mature AAT. Eight relatives of the proband are carriers of the PI*Z la palma allele and four of them have shown symptoms of bronchial asthma or bronchial hyperreactivity. The mean α1AT level in the serum of PI*MZ la palma individuals was 87.1 mg/dl. The reduction in circulating AAT levels associated to the PI*Z la palma allele was similar to that of PI*Z allele, representing a risk of impairment in lung function. Copyright © 2017 Elsevier Ltd.

    Full Text Available La familia Arecaceae es rica en especies, principalmente en el trópico, y constituye una fuente de recursos para la subsistencia de sus pobladores. En el presente trabajo se estudió la riqueza, diversidad, composición y patrones de uso de la familia Arecaceae en tres localidades de la cuenca media del río Atrato en el Chocó, Colombia, con el fin de obtener información que permita su conservación y uso sostenible. Se registraron 29 especies en 18 géneros, siendo Bactris 24.13 y Wettinia 10.34 los géneros más ricos en especies. El Buey mostró más especies y géneros 23 especies, 17 géneros que Beté 15 y 10 respectivamente y Tanguí 14 y 11 respectivamente. La similitud florística entre localidades fue menor al 45. Las especies con mayor peso ecológico y valor de uso fueron: Euterpe oleracea Mart., Oenocarpus bataua Mart., Attalea allennii H.E. Moore, Manicaria saccifera Gaertn., Bactris gassipaes Kunth y Wettinia quinaria O.F.Cook y Doyle R. Bernal. Las categorías de uso con mayor riqueza de especies e importancia cultural fueron: construcción, alimento y uso artesanal; y los órganos más usados fueron tallos y frutos. Los resultados de este trabajo demuestran que el Atrato Medio posee alta riqueza y diversidad de especies de palmas en un contexto regional y nacional. Sin embargo, la relación entre el número de uso y la importancia ecológica de la especie depende de la localidad, lo que indica que la importancia socio-cultural de la especie puede variar entre grupos humanos que comparten una misma cultura o región biogeográfica. Se publicarán estudios a futuro para determinar el papel del tipo de órgano utilizado como materia prima en la demografía y dinámica ecológica de las poblaciones de palma en el Chocó y otras regiones del Neotrópico.

    Full Text Available Resumo Os ecossistemas terrestres são importantes para compreender as trocas de CO2 entre superfície e atmosfera. Este trabalho apresenta as condições atmosféricas e medidas de CO2 em palma de óleo com híbrido interespecífico no leste da Amazônia, durante ano de El niño. O experimento foi realizado em Moju - Pará, onde foi instalada uma torre micrometeorológica para obtenção de dados meteorológicos e de CO2 durante o período de janeiro-dezembro de 2015. Os valores médios diurnos de absorção de CO2 atingiram o máximo por volta do meio dia, com 22,3 (± 0,98 μmol m-2 s-1 no período chuvoso e 21,0 (± 0,47 μmol m-2 s-1 no período menos chuvoso. Houve pouca variação noturna nos valores médios de emissão de CO2, 5 (± 0,20 μmol m-2 s-1, em ambos os períodos. Os valores médios diurnos da concentração de CO2 foram menores e os valores médios noturnos foram maiores. Em geral, o ciclo diário de troca de CO2 apresentou diferença entre o período chuvoso e menos chuvoso. Esses resultados contribuem para melhor compreensão da tendência temporal dos fluxos de CO2 em cultivo agrícola em ano de seca no leste da Amazônia, gerando informações novas sobre a interação entre palma de óleo e atmosfera.

    Full Text Available No processamento tradicional de extração de óleo de palma, uma quantidade substancial do produto é perdida na fibra - durante a etapa de prensagem do fruto - e na borra - durante a etapa de clarificação do óleo cru. A viscosidade deste constitui a principal dificuldade de separação do óleo dos demais componentes da mistura. A eficiência de recuperação do óleo é usualmente melhorada por adição de água, no tanque de clarificação. Neste trabalho avaliou-se os efeitos da diluição e do tratamento enzimático no comportamento reológico do óleo de palma cru. Estes dados são importantes para estimar a velocidade de separação do óleo nos tanques de clarificação e/ou nos decanters das usinas comerciais. O óleo cru utilizado neste estudo foi recolhido em uma unidade comercial sendo composto de 65% de água, 30% de óleo e 5% de sólidos. A hidrólise enzimática foi conduzida usando como agentes hidrolisantes uma enzima comercial (viscozyme da Novo Nordisk e um preparado enzimático produzido no CTAA. Pode-se constatar que quanto mais diluída a amostra maior é a redução na viscosidade após a hidrólise enzimática. Para uma taxa de deformação fixa em 6s-1, o tratamento enzimático do óleo cru a 60°C reduziu a viscosidade do mesmo em cerca de 29% enquanto a adição de 20% de água em cerca de 35%. A combinação da diluição com 20% de água seguida de tratamento enzimático reduziu a viscosidade do óleo cru em cerca de 75%.

  14. Chronology and volcanology of the 1949 multi-vent rift-zone eruption on La Palma (Canary Islands)

    The compositionally zoned San Juan eruption on La Palma emanated from three eruptive centers located along a north-south-trending rift zone in the south of the island. Seismic precursors began weakly in 1936 and became strong in March 1949, with their foci progressing from the north of the rift zone towards its south. This suggests that magma ascended beneath the old Taburiente shield volcano and moved southward along the rift. The eruption began on June 24, 1949, with phreatomagmatic activity at Duraznero crater on the ridgetop (ca. 1880 m above sea level), where five vents erupted tephritic lava along a 400-m-long fissure. On June 8, the Duraznero vents shut down abruptly, and the activity shifted to an off-rift fissure at Llano del Banco, located at ca. 550 m lower elevation and 3 km to the northwest. This eruptive center issued initially tephritic aa and later basanitic pahoehoe lava at high rates, producing a lava flow that entered the sea. Two days after basanite began to erupt at Llano del Banco, Hoyo Negro crater (ca. 1880 m asl), located 700 m north of Duraznero along the rift, opened on July 12 and produced ash and bombs of basanitic to phonotephritic composition in violent phreatomagmatic explosions ( White and Schmincke, 1999). Llano del Banco and Hoyo Negro were simultaneously active for 11 days and showed a co-variance of their eruption rates indicating a shallow hydraulic connection. On July 30, after 3 days of quiescence at all vents, Duraznero and Hoyo Negro became active again during a final eruptive phase. Duraznero issued basanitic lava at high rates for 12 h and produced a lava flow that descended towards the east coast. The lava contains ca. 1 vol.% crustal and mantle xenoliths consisting of 40% tholeiitic gabbros from the oceanic crust, 35% alkaline gabbros, and 20% ultramafic cumulates. The occurrence of xenoliths almost exclusively in the final lava is consistent with their origin by wall-rock collapse at depth near the end of the eruption

    Full Text Available En el contexto del dinamismo y contradicciones del sector agroalimentario, en la actualidad los pequeños productores son impulsados a emprender una reestructuración de sus prácticas productivas, a través de la plantación de cultivos orientados a biocombustibles, como el de la palma africana. En este artículo se analizan los procesos de reestructuración productiva, promovida por corpora-ciones de distinto origen y por el Estado, y las acciones realizadas por pequeños productores en un municipio con alta marginación, localizado en una región agroexportadora de Chiapas. Se revisan las contradicciones sociales y ambientales de este cambio y sus implicaciones a futuro, en términos del desarrollo agrícola y alimentario nacional. La expansión de este cultivo acentúa las desigualdades sociales, degrada los recursos naturales, utiliza mucha energía fósil, impulsa la concentración de la tierra, debilita los sistemas locales de provisión de alimentos y reduce los márgenes del valor generado en la cadena agroalimentaria para los pequeños productores.

    2013-07-01

    Full Text Available This study is intended to compare the complete filmographies of the three American directors whose works are analyzed. They are Clint Eastwood, Brian De Palma and Woody Allen. We define the approach as a trampoline for leaping over the wall of a difficult conceptual and methodological blind alley—an understanding of movie editors and their task, but above all their contribution. Their work is disguised as something merely technical and obvious but, even in the best of cases, this attitude never anything other than lazy. It is the analysis route upheld and cultivated by the David Bordwell and Barry Salt that we are prepared to travel along. If we want to abjure an unsustainably radical anti-empiricism without precipitating ourselves into neo-empiricist infantilism or regressing to a chaotic teratology—that is: to try to remain focused on both the wood and the trees—a statistical-type study, aided by the latest-generation digital and computer tools and, more specifically, an Average Shot Length study (which we will refer to from now on with the acronym ASL appears to us an objective and, consequently, literally unobjectionable criterion. It is probably as reductionist as it is stimulating when it comes to reaching conclusions that are non-definitive but undoubtedly worthy of interest, because, faced with the subjectivity of the analysis and at the general macroscopic level of the movie, the normative and the standard blends with the deviant, or exceptional.

    The green iguana (Iguana iguana) is said to be primarily sedentary, although the females travel long distances to nest. Displacement patterns must be known to help predict the effects of environmental disturbance on iguanas' survival. We studied nesting season (February-July) movements in La Palma, Los Tuxtlas, Veracruz, Mexico (18 degrees 33' N, 95 degrees 03' W). Individual movements and activity were monitored by radio tracking. The transmitters were implanted surgically in eight adult iguanas (four males and four females). Snout vent length (SVL) was used to determine the relationship between size of the body and size of home range. To estimate the size of home range, three or more points were used. Minimum convex polygons estimates of home range were calculated with McPAAL. The iguanas were radio-located between 23 and 30 occasions, mainly in trees (56% between 3-9 m); only 4% were localized under a height of 3 m (forest floor). The occupation area mean was larger for males (9,158.06+/-3,025.3 m2 vs. 6,591.24+/-4,001.1 m2) although the differences were not significant (t= 0.51, p>0.05). SVL was correlated with home range (r= 0.76; gl= 7; piguanas use the riparian vegetation for foraging. The females display two strategies for nesting: 1) moving to the sandy area near the sea or, 2) laying eggs near the river, in loam. Iguanas responded to habitat fragmentation and reduction by modifying their nesting strategy.

Actualmente las plantas productoras de aceite que usan la palma africana como materia prima enfrentan un grave problema, al no saber qué hacer con el desecho final del proceso de producción del aceite. Este desecho posee características mecánicas interesantes: una alta dureza, alta resistencia al desgaste y bajo peso o poca densidad. Estas características la han sabido aprovechar los cultivadores e industriales, pues en lugar de llevar este excedente a botaderos, lo arrojan sobre las vías internas de las plantaciones como material base o capa de rodadura, mejorando así la movilidad de las mismas. Este artículo presenta los satisfactorios resultados parciales de la investigación, que nos motivan a continuar trabajando en este tema.

    Full Text Available Se estudió la producción de biodiesel de aceite crudo de palma mediante el uso de catalizadores heterogéneos ácidos y básicos para las etapas de preesterificación y transesterificación respectivamente. La pre-esterificación es necesaria para aceites con una acidez superior al 4% de ácidos grasos libres, ya que se evitan los problemas asociados con la formación de jabones. En ambas reacciones las variables analizadas fueron el tipo de catalizador, la temperatura y el tiempo. Se analizó la conversión del aceite a metilésteres usando cromatografía gaseosa y la estabilidad de los catalizadores mediante su reutilización. En la etapa de pre-esterificación se encontró que catalizadores ácidos del tipo resinas de poliestireno sulfonadas presentan conversiones superiores al 87% estabilidad para la esterificación de los ácidos grasos libres. Para la transesterificación se estudiaron como catalizadores heterogéneos, el carbonato de potasio libre y soportado en una matriz polimérica, obteniéndose con ambos conversiones superiores a 95 % de biodiesel; con el uso del soporte polimérico se disminuyó la velocidad de disolución de carbonato de potasio, permitiendo su reutilización hasta 10 reutilizaciones.

    Full Text Available The western Canaries, relatively little studied until a few years ago from the geological point of view, have however provided decisive data for understanding many of the most important geological problems of the Archipelago, which would probably have been dilucidated earlier, had the study begun with the most recent islands, as occurs in similar chains of oceanic volcanic islands in other parts of the world. To summarize the main geological features and evolutionary characteristics of both islands we emphasize the following stages of development: During the Pliocene, a submarine volcanic edifice or seamount formed in the island of La Palma, made up of pillow lavas, pillow breccias and hyaloclastites, intruded by trachytic domes, plugs of gabbros, and a highly dense dyke swarm. The intense magmatic and dyke intrusion uplifted the searnount up to 1,500 m, tilting it 45-50" to the SW. This intrusive phase was followed by a period of quiescence and erosion of the emerged submarine edifice. The definitive consolidation and progression of the construction of the island continued from at least 1.77 ma in angular and erosive discordance over the submarine basement. The subaerial volcanic reactivation, in which explosive volcanism predominated during the initial stages, producing abundant volcanoclastic and phreatomagmatic materials at the base of the subaerial edifice, persisted in a highly continuous manner until at least 0.41 ma. This initial subaerial stage shaped the northern volcanic shield, formed by the accumulation of several superimposed volcanoes, approximately concentric in relation to one another and the submarine basement. The initial stage of the northern volcanic shield lasted between 1.77 and 1.20 ma, during which period the Garafía volcano was built to a height of 2,500-3,000 m, with steeply sloping flanks, formed predominantly by alkaline basalts with abundant pahoehoe lavas. The rapid growth and progressive instability of the Garaf

    Three different palaeointensity methods were applied to six historical and three carbon-dated flows from the island of La Palma (Spain); in total fifteen sites were processed. The two 20th-century flows were sampled at multiple locations as their obtained directions and intensities can be compared directly to those from the International Geomagnetic Reference Field (IGRF). After determination of the declinations and inclinations of the natural remanent magnetisation (NRM) by thermal and alternating-field demagnetisation, the samples were subjected to standard rock magnetic analyses to determine their Curie and alteration temperatures. Based on these characteristics, the sites were allocated to one of four rock magnetic groups labelled L∗, L, C, and H, a division primarily based on the temperature-dependent behaviour of the low-field susceptibility that has been used in studies of other volcanic edifices. Scanning electron microscope (SEM) observations revealed little oxidation and exsolution (oxidation classes I to III). Palaeointensities were determined using the classic Thellier-Thellier method (Aitken and IZZI protocols), the microwave method and the domain-state-corrected multispecimen method. Thellier-Thellier and microwave results were analysed using the ThellierTool A and B sets of selection criteria as modified by Paterson et al. (2014). Their combined success rate was around 40%. Of the eight IGRF sites, two yielded average intensities within 10% of the IGRF value. For the microwave method, three sites reproduced the IGRF intensity within 10%. In the domain-state-corrected multispecimen protocol, just one site (site 9, 1971) passed the 'ARM-test' (applied in retrospect) and showed less than 3% progressive alteration. Its multispecimen result reproduced the palaeofield within error. The other IGRF sites over- or underestimated the palaeofield by up to 50%. The seven older sites produced plausible palaeointensities, generally within a few μT of model data

    A field experiment on Sesbania aculeata and Sorghum bicolor grown in mono cropping and in inter cropping systems was conducted under non-saline conditions (soil EC sub e 0.16, water EC sub w 1 ds/m/m) to evaluate dry matter production, total N yield, soil N uptake and N sub 2 -fixation using sup 1 sup 5 N isotope dilution method. Three different row ratios of sesbania (ses) and sorghum (sor) were subjected in the inter cropping system (2 ses: 1 sor; 1 ses: 1 sor and 1 ses: 2 sor row ratio). Dry matter yield of sole sorghum was higher than that of sole sesbania, and it was similar to that produced by the inter cropping treatments. However, total N yield of sole sorghum was significantly the lowest, with no differences being obtained between sole sesbania and inter cropping treatments. The LERs of total N yield were, in all cases, higher than 1, reflecting a greater advantage of inter cropping system in terms of land use efficiency. Percentages of N sub 2 fixation in the inter cropped sesbania were considerably enhanced compared with the pure stand of sesbania. This was mainly attributed to the depletion of soil N resulting from the greater apparent competitiveness of sorghum for soil N, and consequently, a greater dependence of sesbania on N sub 2 fixation. However, the degree of the intraspecific competition for soil N uptake was affected by the proportion of crops in the mixture, and it was considerably reduced in the 2 ses: 1 sor row ratio. This was demonstrated when an equal depletion of soil and fertilizer N uptake occurred for both crops. We excluded in all-inter cropping treatments the possibility of N transfer from sesbania to sorghum. Row inter cropping, with crops grown in alternation of two rows of sesbania with one row of sorghum, seemed to be the most adequate row ratio in terms of total N yield, LER, N sub 2 -fixation and soil N uptake balance of the component crops.

  2. Shallow fractionation signature of phase chemistry in Taburiente lavas, La Palma, Canary Islands: Results of MELTS modeling

    Depth of crystal fractionation influences the chemical evolution of ocean island basalts and has significant implications for the physical structures of these volcanoes. In contrast to dominantly shallow systems such as Hawaii, a range of fractionation depths have been reported for Canary Islands lavas. Magmas erupted on La Palma preserve fluid- and melt-inclusion evidence for high-pressure (> 10 kbar) crystallization (Klügel et al., 1998; Hansteen et al., 1998; Nikogosian et al., 2002). If high-pressure fractional crystallization were an early and dominant process, it would generate specific patterns in rock and phase chemistry of eruptive sequences. Alkalic basalts from Taburiente volcano display coherent major element trends consistent with evolution dominated by fractional crystallization while their phenocryst compositions, trace elements, and isotopic trends require mixing between multiple sources. The current model confirms the importance of both fractionation and mixing to achieve the full range of lavas observed. A low-pressure (1 kbar) thermodynamic fractional crystallization model performed with the MELTS (Ghiorso and Sack, 1995) software closely reproduces major element trends from two stratigraphic sequences. This model also predicts the observed sequence of groundmass clinopyroxene compositions and phenocryst zoning reversals. In all low pressure simulations, olivine remains a modally significant liquidus phase during the first 20% and last 30% of the crystallization sequence, resulting in a negative correlation between the CaO and Fo content of olivine. These results are consistent with the presence of olivine phenocrysts that bear petrographic evidence of early crystallization, as well as observed compositional trends of groundmass olivine and clinopyroxene in Taburiente lavas. MELTS models that include an initial period of high pressure (12 kbar) clinopyroxene fractionation produce major element trends comparable to the low pressure model, but

  4. Spatial and temporal characterization of some water quality physical parameters and their relationships with land-use in Água Fria watershed (Palmas – TO, Brazil

    Directory of Open Access Journals (Sweden)

    Harry Edmar Schulz

    2007-06-01

    Full Text Available Due to a high population growth that has been occurring in Palmas and due to land use changes that are caused by this population growth and development, the goal of this paper was to study the behavior of four physical parameters of water quality of the Água Fria watershed. The parameters were turbidity, total suspended solids, settleable solids and total dissolved solids. Eight gauging stations were established and the water samples were monthly collected from February/1998 to February/1999. The water bodies of the watershed were generally in good condition concerning these four parameters. However, there were some cases of seasonal irregularity of some parameters, as well as no correlation among some of studied parameters. This might be an indicator of some impacts like accelerated erosion due to a misuse of the lands and misuse of local water resources.

    In this paper the materials of the glass furnace of Sa Gerreria (Palma) dated in the second half of the 17th Century A.D. are analysed. On the one hand, we discuss the available information regarding this glass workshop as well as the raw material management strategies made during the studied period. On the other hand, we focus on the materials produced by this workshop and we carry out a preliminary archaeometrical analysis of the glass lumps, frits and slags recovered as well as some glass pieces by means of scanning electron microscope and X-ray dispersive energy. The final aim is to characterise the chemical composition and the properties of the raw materials used in this workshop as well as to approach some of the technical processes put in practice by the glass makers who inhabited Mallorca during the 17th Century.

    Full Text Available Se produjeron carbones activados a partir de carbón de El Cerrejón y del Cuesco de Palma Africana mediante activación con vapor de agua y KOH, a 700 y 800 ó 900°C variando la relación activante/carbonizado y el tiempo de activación. Los tiempos de activación a los que se desarrolla mayor área superficial son mucho más cortos con el vapor de agua que con el KOH. Al activar con este último se obtienen valores de área superficial similares errlas dos materias primas, según la temperatura de trabajo, mientras que la activación con vapor de agua, presenta características totalmente diferentes. La activación del Cuesco de Palma Africana con KOH, produce carbones esencialmente microporosos, mientras que con vapor de agua, produce carbones activados con una apreciable mesoporosidad favorecida por el incremento de la temperatura. La activación del carbón de El Cerrejón con KOH o vapor de agua produce carbones activados microporosos. En líneas generales se puede decir que el tipo de textura porosa obtenida en la producción de un carbón activado, es función no sólo de los agentes activantes utilizados, sino también del tipo u origen de la materia prima, mientras que la calidad del carbón activado, (área superficial total, es función del tiempo y de la temperatura de activación, al menos con los materiales de partida usados en este trabajo.

  8. Tierra, palma africana y conflicto armado en el Bajo Atrato chocoano, Colombia. Una lectura desde el cambio en los órdenes de extracción

    Full Text Available Desde la década de 1990 la región del Pacífico colombiano vive un proceso inédito de agudización del conflicto armado interno. Algunos estudios han descrito este hecho como una consecuencia no intencionada del reconocimiento de las poblaciones negras de la región como grupos étnicos propietarios de los territorios en los que habitan. En este artículo me pregunto de qué forma resultaron modificadas las dinámicas de conflicto en la subregión del Bajo Atrato chocoano (1985-2005 en Colombia, si esto se vincula con la explotación de sus recursos naturales, en particular la palma de aceite y cuál fue el papel que jugó en estas dinámicas el cambio en el régimen de propiedad de la tierra. Para responder a estas preguntas me baso en los estudios sobre la economía política de los conflictos armados e introduzco el concepto de órdenes de extracción con el fin de analizar las acciones de los actores del conflicto, los empresarios de la palma, el Estado como agente regulador y las poblaciones negras. Mi conclusión principal es que el cambio en la estructura de propiedad de la tierra no fue causa del conflicto y que el tipo de actor involucrado es una variable relevante.

    O presente trabalho teve como objetivo avaliar as alterações oxidativas produzidas nos óleos de algodão, girassol e palma, durante o processo de fritura descontínua de mandioca palito congelada. As frituras foram conduzidas em uma fritadeira elétrica doméstica, onde o óleo foi aquecido, à temperatura de 180°C, por 25 horas, com reposição de óleo fresco. Os resultados obtidos das determinações analíticas foram submetidos às análises de variância, em esquema fatorial, no delineamento inteiramente casualizado, de modo a determinar a influência dos fatores óleos e tempos de fritura sobre as alterações nos óleos e no produto. Os resultados mostraram que as menores alterações ocorreram para o óleo de palma, mais saturado. Para os óleos de algodão e girassol, mais insaturados, verificou-se que ao longo dos tempos de frituras ocorreu um aumento da formação dos compostos de degradação e diminuiu a estabilidade oxidativa. Apesar das diferenças na composição em ácidos graxos, os óleos estudados não apresentaram, em nenhuma análise, valores acima dos limites recomendados, independentemente do tempo de aquecimento. PALAVRAS-CHAVE: Óleos vegetais; alterações oxidativas; estabilidade oxidativa; frituras.

    Trichoderma spp and Gliocladium spp have been reported as control agents of some of the fungi that cause root rot diseases in various crops. Despite this potential the there is no information on their ecology in tropical soils. This study was conducted at the Palma de Vino farm, La Dorada, Caldas with the aim of contributing to the understanding of their ecology in their natural habitat in the tropics. Representative soil and rhizosphere samples were collected and analyzed for some physical, chemical, and biological properties. The results showed clearly that: 1) both genera, form part of the native microflora of those soils. 2) The Trichoderma spp population fluctuated between 5.7x10 2 and 6.4x10 3 and between 7.4x10 2 and 2x10 4 UFC g - 1 in the soil and rhizoplane, respectively; the Gliocladium spp population could not be estimated, probably due to their low numbers. 3) Within the genus Trichoderma the species T. Hamatum, T. Harzianum, and T. Koningu could be identified. 4) The Trichoderma spp populations, especially those from de rhizoplane, showed a clear relation with de soil pH. As far as we know, these results represent the first source of information on the ecology of these two agronomic important fungi, under tropical conditions

    Full Text Available En este artículo se presenta el estudio de la hidrólisis del crudo de aceite de palma por medio de la lipasa Candida rugosa. Los factores estudiados en esta investigación fueron el nivel de agitación, el efecto de blanqueo y la cantidad de lipasa. Experimentalmente fueron alcanzados porcentajes de hidrólisis del 79 - 93% en períodos de tiempo de 2 horas y media. Se pudo obtener un incremento de la reacción al aumentar la rotación del agitador al igual que incrementando la concentración de lipasa. Aunque la literatura cita el blanqueado como una ventaja para la hidrólisis enzimática, este procedimiento parece no tener un efecto benéfico en la reacción. / This paper shows the study of the hydrolysis reaction of crude palm oil giving by lipase from Candida rugosa. The studied factors were agitation level, bleaching effect and lipase concentration. Experimentally 79 - 93% hydrolysis were achieved in 2 and a half hour.

    "Dragon[prime or minute]s blood" is the name applied to the deep-red coloured resin obtained from various plants. The original source in Roman times, used by many cultures and esteemed for its depth of colour and mystical association, was the dragon tree Dracaena cinnabari(Convallariaceae), found only on the Indian Ocean island of Socotra, (Yemen). Additional sources emerged later, including another species of Dracaena, D. draco, from the Canary Islands and Madeira, and species in the genera Daemonorops(Palmae) from South East Asia and Croton(Euphorbiaceae) from tropical parts of both the New and Old Worlds. In this study, examples of dragon's blood resins from the Economic Botany Collections at the Royal Botanic Gardens, Kew, dating from 1851 to 1993, have been analysed non-destructively using Raman spectroscopy. The Raman spectra of well-documented, provenanced specimens have been used to establish the source of specimens of questionable or unknown origin. It has also been possible from the Raman spectra to indicate whether processing of the resins has been undertaken in the preparation of the specimens before their deposition at Kew.

    Full Text Available INTRODUCTION: The aim of the present study was to identify the presence of Leishmania (Leishmania chagasi infection in dogs in the City of Palmas, Tocantins, Brazil, using the PCR technique to list the hot spots of infected dogs in the city and associate their occurrence to significant environmental changes at capture sites. METHODS: DNA was extracted from blood of dogs, and the PCR were performed with primers RV1/RV2. After screening the population studied, the regions of the city that had the highest occurrence of canine infection were detected. These sites were visited, and ecological parameters denoting anthropogenic disturbance were evaluated. RESULTS: Some important features were listed in the regions visited, such as low urbanization, lack of public collection of sewage, limited garbage collection, vacant lots with tall vegetation, decaying organic matter, and, most importantly, the occurrence of stray dogs and poultry in homes. CONCLUSIONS: The methodology for screening the population was very efficient, especially in evaluating a large number of individuals in a short time, with a high degree of automation. The results indicate an association between the observed parameters and the occurrence of infection in dogs. The model presented in the city is ideal for studies of disease progression and expansion and for the evaluation of control measures adopted for canine VL.

    Between the 19th and 25th April 1914, the First Spanish Congress of Paediatrics was held in Palma de Mallorca under the slogan "Protect the Children". The specialty had broken away a few years earlier from its secular connection with Obstetrics and Gynaecology, both in its teaching aspect as well as regarding healthcare. With the newly created Chairs in Childhood Diseases, in a way this Congress meant the coming-of age and debut int society of paediatrics in our country. Prof. Martínez Vargas, a university professor in Barcelona, was the Chairman, and soul of the congress. There was a need to face a very high rate of infant mortality. The Congress responded to that social and sanitary/health demand with the participation of over three hundred pediatricians, including foreign representatives from Belgium, France, Russia and Latin America. The activities were divided into four sections: Childcare, Child Medicine, Surgery and Health, and accredited lecturers gave master classes on the most pressing issues of child pathology of the time. One hundred years on, what we are today is the fruit gathered by those who preceded us. Some were brilliant figures in paediatrics and others, the majority, anonymous paediatricians. They dedicated their lives, their science and their best smile to child care. The way we were and the way we are. With legitimate pride and satisfaction, it is an honour for the Group on the History of Paediatrics and AEP Documentation to celebrate this centennial commemoration in the framework of the Annals of Paediatrics.

  3. The chemically zoned 1949 eruption on La Palma (Canary Islands): Petrologic evolution and magma supply dynamics of a rift zone eruption

    The 1949 rift zone eruption along the Cumbre Vieja ridge on La Palma involved three eruptive centers, 3 km spaced apart, and was chemically and mineralogically zoned. Duraznero crater erupted tephrite for 14 days and shut down upon the opening of Llano del Banco, a fissure that issued first tephrite and, after 3 days, basanite. Hoyo Negro crater opened 4 days later and erupted basanite, tephrite, and phonotephrite, while Llano del Banco continued to issue basanite. The eruption ended with Duraznero erupting basanite with abundant crustal and mantle xenoliths. The tephrites and basanites from Duraznero and Llano del Banco show narrow compositional ranges and define a bimodal suite. Each batch ascended and evolved separately without significant intermixing, as did the Hoyo Negro basanite, which formed at lower degrees of melting. The magmas fractionated clinopyroxene +olivine±kaersutite±Ti-magnetite at 600-800 MPa and possibly 800-1100 MPa. Abundant reversely zoned phenocrysts reflect mixing with evolved melts at mantle depths. Probably as early as 1936, Hoyo Negro basanite entered the deep rift system at 200-350 MPa. Some shallower pockets of this basanite evolved to phonotephrite through differentiation and assimilation of wall rock. A few months prior to eruption, a mixing event in the mantle may have triggered the final ascent of the magmas. Most of the erupted tephrite and basanite ascended from mantle depths within hours to days without prolonged storage in crustal reservoirs. The Cumbre Vieja rift zone differs from the rift zones of Kilauea volcano (Hawaii) in lacking a summit caldera or a summit reservoir feeding the rift system and in being smaller and less active with most of the rift magma solidifying between eruptions.

    Cicer canariense is a threatened perennial wild chickpea endemic to the Canary Islands. In this study, rhizobia that nodulate this species in its natural habitats on La Palma (Canary Islands) were characterised. The genetic diversity and phylogeny were estimated by RAPD profiles, 16S-RFLP analysis and sequencing of the rrs, recA, glnII and nodC genes. 16S-RFLP grouped the isolates within the Mesorhizobium genus and distinguished nine different ribotypes. Four branches included minority ribotypes (3-5 isolates), whereas another five contained the predominant ribotypes that clustered with reference strains of M. tianshanense/M. gobiense/M. metallidurans, M. caraganae, M. opportunistum, M. ciceri and M. tamadayense. The sequences confirmed the RFLP groupings but resolved additional internal divergence within the M. caraganae group and outlined several potential novel species. The RAPD profiles showed a high diversity at the infraspecific level, except in the M. ciceri group. The nodC phylogeny resolved three symbiotic lineages. A small group of isolates had sequences identical to those of symbiovar ciceri and were only detected in M. ciceri isolates. Another group of sequences represented a novel symbiotic lineage that was associated with two particular chromosomal backgrounds. However, nodC sequences closely related to symbiovar loti predominated in most isolates, and they were detected in several chromosomal backgrounds corresponding to up to nine Mesorhizobium lineages. The results indicated that C. canariense is a promiscuous legume that can be nodulated by several rhizobial species and symbiotypes, which means it will be important to determine the combination of core and symbiotic genes that produce the most effective symbiosis.

Local species richness (species per 0.5 km transects showed an important geographical component, increasing from south to north, from west to east, and reaching maximum values at altitudes around 600-1,000 m a.s.l. It was also positively related to vegetation development (specially in the herbaceous and shrub layer, and negatively associated with urbanization and agriculture. Total bird density reached the highest figures in the ‘monteverde’ (laurel and heath forests ca. 650 aves/km2, and in the transition pinewoods-laurel forests (509 aves/km2, while the lowest figures were recorded in high altitude shrublands (153 aves/km2 and recent lava fields (58 aves/km2. The bird species with lower population sizes are Falco [peregrinus] pelegrinoides, Burhinus oedicnemus distinctus, Upupa epops, Carduelis carduelis, Miliaria calandra and Petronia petronia, while the last five species have undergone more negative population trends in the last 15-25 years.

    Volcanic activity at La Palma (Canary Islands) in the last 123 ka has taken place exclusively at the southern part of the island, where Cumbre Vieja volcano, which is characterized by a main north-south rift zone 20 km long and up to 1950 m in elevation and covering an area of 220 km2 with vents located also at the northwest and northeast. Cumbre Vieja is the most active basaltic volcano in the Canaries with 7 historical eruptions being San Juan (1949) and Teneguía (1971) the most recent ones. Since no visible degassing (fumaroles, etc.) at Cumbre Vieja occurs, our geochemical program for the volcanic surveillance of Cumbre Vieja is mainly focused on diffuse degassing monitoring. Diffuse CO2 emission surveys are yearly performed in summer to minimize the influence of meteorological variations. About 570 sampling sites were selected for each survey to obtain a homogeneous distribution after taking into consideration the local geology, structure, and accessibility. Measurements of soil CO2 efflux were performed in situ by means of a portable non-dispersive infrared sensor following the accumulation chamber method. The soil CO2 efflux values of the 2017 survey ranged from non-detectable to 47.7 g m-2 d-1. Statistical-graphical analysis of the data show two different geocheleemical populations; background (B) and peak (P) represented by 98.2% and 1.8% of the total data, respectively. The geometric means of the B and P populations are 2.9 and 36.5 g m-2 d-1, respectively. Most of the area showed B values while the P values were mainly observed both flanks of the main N-S volcanic rift. To estimate the diffuse CO2 emission in metric tons per day released from Cumbre Vieja (220 km2) for the 2017 survey, we ran about 100 sGs simulations. The estimated 2017 diffuse CO2 output released to atmosphere by Cumbre Vieja was at 801 ± 27 t d-1, value relatively higher than the background average of CO2 emission estimated on 374 t d-1 and within the background range of 132 t d-1

    The Palma Sola-Chiconquiaco mountain range, situated in the State of Veracruz, Mexico, is highly susceptible to landslides, which is evidenced by the high frequency of landslide events of different sizes. The study area is located near the Gulf of Mexico coastline in the eastern sector of the Trans Mexican Volcanic Belt. There, landslide triggers are intense rainfalls related to tropical storms and hurricanes. Steeper slopes are commonly affected by rockfalls, whereas moderate slopes, covered by massive slope deposits, are affected by shallow as well as deep seated landslides. Some of the landslides in the slope deposits reach dimensions of more than 1000 m in length and depths of over 30 m. The heterogeneous parent material as well as older slide masses hamper the detailed characterization of the involved materials. Therefore, in this study, a multidisciplinary approach is applied that integrates geomorphological, geological, and geophysical data. The aim is the reconstruction of process dynamics by analyzing the geomorphological situation and subsurface conditions before and after the event. The focus lies on the identification of past landslide areas, which represent areas with high susceptibility for the reactivation of old slide masses. Furthermore, the analysis of digital terrain models, generated before the landslide event, indicate initial movements like extension cracks, which are located close to the current scarp area. In order to characterize the subsurface of slide masses geophysical investigations are applied. The geophysical survey consists of a total of nine profiles covering relevant key features of the large affected area. Along these profiles, electrical resistivity tomography (ERT) and seismic refraction tomography (SRT) data were collected. Both, electrical and seismic images reveal a sharp contrast between relatively loose and dry material of the slide mass (high resistivities and low seismic velocities) and the former land surface that is

I argue that by citing different versions of the ethnographic portrait visual genre, the Serie builds a temporal arc that extends from the sixteenth century to the Five Hundred Years celebrations (1992. This arc allows us to explore the relation between Art and Anthropology, the representation of Guatemalan indigenous subjects, violence and coloniality in a continued, long-lasting process. In the first part the article delves in a critical and theoretical discussion of the ethnographic turn in art (Kosuth, Foster in a latinamericanist (Camnitzer, Richard, postcolonial and decolonial context (Coronil, Mignolo, Quijano. In the second part, I revise the use of the ethnographic portrait (Brilliant and Mason, Parker Brienen, Lugo Ortiz in racial formations (Omi and Winant in the Americas to further comprehend the presence of this visual genre in Gonzalez Palma´s works, its critical sense, and finally the artist´s proposal to recover “the gaze as power”.

    Full Text Available The results from the paleomagnetic analysis of the plio-pleistocene deposits located in the eastern (Bahia Azul Section and western (Banc d'Eivissa borders of the Palma Basin are presented in this paper. The Bahía Azul section is composite by a marine terrace at +70-74 m a.s.1., overlapped by nine littoral dune systems separated by erosional surfaces. The Banc d'Eivissa section is constituted of a lower marine terrace at +24-25 m a.s.l., buried by two dune systems, although there are more numerous in the vicinity. The lithological spectrum at both sections holds a main calcarenitic nature, but the available outcrops display a different degree of weathering making difficult the establishment of a continuous magnetoestratigraphic sequence. The paleontological content (Roselló y Cuerda, 1973 and paleomagnetic results of the Banc d'Eivissa deposits are no sufficient to establish a precise chronological sequence, and only is possible to locate them within the reverse polarity Matuyama epoch. On the contrary, the lower half of the Bahia Azul sequence (marine terrace plus the 3 first dune systems presents a consistent reverse polarity. The paleontological content of these materials indicates an early Pleistocene age (Emilian cycle: Cuerda y Sacarés, 1992 which agree with the obtained paleomagnetic results. Therefore, the whole sequence is interpreted to be located between the normal polarity chrons of Jaramillo and Olduvay (Clr. 1n and C2n of Cande and Kent, 1995 within the Matuyama epoch, but can not be totally rejected the possibility that them could be placed after the Olduvai Chron.Se presentan los resultados paleomagnéticos obtenidos del análisis de los depósitos plio-pleistocenos que afloran en los bordes oriental (sección de Bahía Azul y occidental (Banc d'Eivissa de la cuenca de Palma.

    Full Text Available No ano de 2007, enquanto se desenvolviam os estudos para a criação do Plano Diretor Participativo de Palmas, foi constatada uma significava redução e ocupação irregular das áreas verdes e das matas ciliares na área urbana do município. Como tentativa de conter esses impactos, o poder público transformou as áreas verdes que margeiam os cursos d’água em Unidades de Conservação (UC. No entanto, o que se tem observado é que estas UCs, da forma em que se encontram, não têm atingido os objetivos esperados. O zoneamento ambiental é um dos principais instrumentos de gestão de uma UC, além de ser uma importante fonte de informações para a sua devida categorização. Sendo assim, o presente estudo apresenta o zoneamento ambiental da área proposta da UC Tiúba, levando em consideração a cobertura e uso do solo e as fragilidades ambientais da área, constituído em quatro zonas: sendo duas com o objetivo de proteger as margens dos recursos hídricos e as áreas com vegetação nativa, uma zona temporária para garantir a recuperação das áreas que se encontram degradadas e a outra zona para promover o desenvolvimento de forma sustentável por meio da ocupação controlada da área. ABSTRACT In 2007, during the development of the studies for the creation of a Participative Master Plan of Palmas, it was observed a significant reduction and an illegal occupation of the green areas and the riparian forests in the urban area of the municipality.

    The sediments are an important compartment used as a tool for assessment of aquatic ecosystems quality, for indicating the presence of contaminants released continuously into the environment as a result of human activities. Among chemical substances discharged to surface water, there are metals that in undesirable amounts, can be toxic to biota. Due to the importance of sediment and of shortage of data of water quality of the Araguaia-Tocantins river system, the present study conducted an assessment of environmentally available metals in sediment samples from water for public supply of the city of Palmas, in Tocantins, Brazil. The concentrations of As, Cd, Pb and Se were analyzed by Graphite Furnace Atomic Absorption Spectrometry (GFAAS), Ag, Al, B, Ba, Be, Ca, Co, Cr, Cu, Fe, K, Li, Mg, Mn, Mo, Na, Ni, P, Sb, Sc, Si, Ti, V and Zn were analyzed by Inductively Coupled Plasma Optical Emission Spectrometry (ICPOES) and Hg by Cold Vapor Atomic Absorption Spectrometry (CVAAS). Two partial solubilization processes were performed for a comparative study, one with HCl 0,1 M and agitation at room temperature, considered a milder method for metal extraction from anthropogenic origin, and another with HNO{sub 3} 8 M and microwave heating, considered as an alternative to more complex methods of total digestion, since it provides a good evaluation of the total concentration of the elements. The sediment quality evaluation was realized by comparing the concentration values of the elements As, Cd, Cr, Cu, Hg, Ni, Pb and Zn with the quality guidelines (TEL and PEL) adopted by Canadian Council of Minister of the Environment (CCME), to thereby contribute to the environmental quality of the water of the Araguaia-Tocantins river system.

    Full Text Available Macaw palm (Acrocomia aculeata is native to tropical forests in South America and highly abundant in Brazil. It is cited as a highly productive oleaginous palm tree presenting high potential for biodiesel production. The aim of this work was to characterize and study the genetic diversity of A. aculeata ex situ collections from different geographical states in Brazil using microsatellite (Simple Sequence Repeats, SSR markers. A total of 192 accessions from 10 provenances were analyzed with 10 SSR, and variations were detected in allelic diversity, polymorphism, and heterozygosity in the collections. Three major groups of accessions were formed using PCoA—principal coordinate analysis, UPGMA—unweighted pair-group method with arithmetic mean, and Tocher. The Mantel test revealed a weak correlation (r = 0.07 between genetic and geographic distances among the provenances reaffirming the result of the grouping. Reduced average heterozygosity (Ho < 50% per locus (or provenance confirmed the predominance of endogamy (or inbreeding in the germplasm collections as evidenced by positive inbreeding coefficient (F > 0 per locus (or per provenance. AMOVA—Analysis of Molecular Variance revealed higher (48.2% genetic variation within population than among populations (36.5%. SSR are useful molecular markers in characterizing A. aculeata germplasm and could facilitate the process of identifying, grouping, and selecting genotypes. Present results could be used to formulate appropriate conservation strategies in the genebank.

    Full Text Available The Canary Islands have traditionally been a destination for mass tourism, a fact that is not, however, necessarily incompatible with a growing trend towards segmentation in tourist markets. In fact, the experience of other traditional destinations, like the Balearic Islands, shows that the two trends can take place at the same time. This article presents the results of a segmentation study carried out on a representa-tive sample of the tourist market for the island of La Palma (Canary Islands in early 2002. More specifi-cally, we cross demand segments and services to study a possible imbalance between tourist expectations for the services offered and the services that are actually contracted in the destination. The segments studied were: nationality (German and Spanish, income and type of establishment; and the services studied: excur-sions, recreational activities in general and sports activities in particular. The results show that the best posi-tive response to the destination is found for excursions for both nationalities. For the other services offered, however, (recreational activities and more specifically sports activities, the response differs substantially from one nationality to another, suggesting that the destination in general is in a better position to cover the contracting expectations of Spanish domestic tourism. In summary, the results of the study lead us to con-clude that the cultural factors associated with nationality have the strongest influence on defining tourist service consumer behaviour

    Full Text Available This study investigated the discontinuous frying of breaded meat products in palm olein in a 28 L-electric fryer maintained at 182 ºC for 8 hours a day. Three 400-500 g batches of meat products were fried for 4.5 minutes daily. For comparison purpose, thermoxidation tests were performed using inert material with added moisture and without the addition of f ood (heating only. The total polar compound content did not reach the 25% limit, and nor did the formation of polymerized products exceed 5%, which indicates the good frying performance of palm olein for frying. Other analytical parameters and rapid tests were also evaluated. The sensory attributes, such as odor, colour, and foam formation determined when the frying oils should be discarded. The addition of water to the inert material contributed to the final value of 1.00 ± 0.01% (in palmitic acid, while the oil subjected only to heating reached respectively 0.26 ± 0.02%, and the oils used to fry breaded meat and breaded chicken reached 0.38 ± 0.00% and 2.35 ± 0.01%, respectively. This suggests a protective effect of the water during frying since the oil subjected only to heating was more prone to degradation.Este artigo estudou a fritura descontínua de alimentos cárneos empanados em oleína de palma em uma fritadeira elétrica de 28 L, mantida a 182 ºC durante 8 horas por dia.

En este panorama, la investigación sobre la utilización de combustibles alternativos es de suma relevancia, en particular el estudio del rendimiento de motores al usar mezclas de Biodiesel Colombiano a base de aceite de palma con Jet A1.  Método: como punto de partida, se realiza una revisión al estado del arte para la selección del motor a estudiar y los combustibles alternativos a utilizar. Paralelamente, se seleccionó el biodiesel colombiano a base de aceite de palma, ya que ha demostrado tener un buen comportamiento como combustible al ser mezclado en porcentajes de 10% ,20% y 50%. A cada una de las mezclas realizadas se les hicieron pruebas en laboratorio para conocer su valor de viscosidad, densidad y poder calorífico. Para la realización de los análisis, se desarrolló un programa sobre una hoja de cálculo que contempla Propiedades físicas de las mezclas y parámetros del motor, así como emisiones de óxidos nitrosos (NOx, atomización y combustión producida por el uso de las mezclas. Los resultados se contrastaron contra el software de simulación Gas turbine. Resultados: se escogió el CFM 56-5B como motor apropiado para realizar el estudio, debido a que en la actualidad es el más empleado en la industria aeronáutica colombiana.  Por otra parte, ninguna de las mezclas de combustible alternativo genera el mismo rendimiento del motor al emplear Jet A1. Las mezclas E10 y E20 tienen un comportamiento similar, con la novedad de generar menor cantidad de emisiones de NOx y mejorar la atomización del combustible. Conclusiones: al comparar el rendimiento del motor al usar combustible convencional y al emplear las mezclas de Biodiesel

    Full Text Available Este artigo identificou propriedades micromorfológicas comuns em depósitos de colúvio formados por diferentes processos e condições ambientais, com o intuito de obter informações que auxiliem no reconhecimento de microfeições indicadoras de ambiente úmido.  Para tanto foram comparadas uma seção estratigráfica do Planalto Sedimentar do Araripe com os elementos micromorfológicos do nível 4Cb da seção HS1 na superfície Palmas/Água Doce - Sul do Brasil, gerados na passagem de condições paleoclimáticas secas para úmidas. Os métodos incluem: i descrição com base no critério litoestratigráfico para seção Rampa de colúvio de fácie proximal - CSM-C, e no pedoestratigráfico para a seção HS1; ii caracterização das propriedades sedimentológicas; iii - Descrição e análise micromorfológica dos materiais. O nível 4Cb foi usado como referência por ser de origem coluvial e o principal responsável pela colmatação de um paleocanal de segunda ordem. Comparando a unidade 4Cb, gerada em condições ambientais transicionais de clima mais seco para mais úmido, com a seção CSM-C, pode-se concluir que: I a componente água esteve presente em ambas unidades coluviais, tanto durante quanto após o evento deposicional. Isto demonstra que ambas têm importante significado paleoambiental, sobretudo para o sul do Ceará, que está inserido no contexto semiárido. II as evidências micromorfológicas comuns de depleção e migração de oxihidróxido de ferro permitem apontar que as condições paleoambientais de formação dos colúvios foram similares, gerados na transição de um ambiente mais seco para mais úmido. III o acúmulo das microfeições hidromórficas e de migração dos oxihidróxidos de ferro com aberturas de poros testemunham a continuidade da presença da água no sistema.

    Full Text Available This work aimed to promote in vitro seed germination and disinfestation of the sweet cactus. Seeds were submerged in alcohol at 70% for 1 min. and then treated with sodium hypochlorite solution at different concentrations: 0.0; 0.5; 1.0 and 1.5%. After thistreatment, the seeds were washed four times in distillated, deionized and autoclaved water. Seeds were inoculated in MS medium with different concentrations of sucrose (0.0, 2.5, 5.0, 7.5 and 10.0 g L-1. The experimental design was completely randomized in a factorialexperiment 4 x 5, with five replicates for treatments. Contamination, germination and seedling growth were evaluated. The results of the analysis of variance indicate that there were no significant interactions among factors. There was no significance for sucroseconcentrations on contamination but these treatments showed significant differences for seed germination and seedling growth (p . 0.01. At higher sucrose concentrations there was lower germination and smaller seedlings. There were significant differences betweenthe treatments with sodium hypochlorite for all traits analysed (p . 0.01. There was low contamination with the increase in sodium hypochlorite concentrations with higher germination percentage and taller seedlings.Este trabalho objetivou desinfestar e promover a germinacao de sementes de palma doce gin vitroh.

    Full Text Available Este artículo presenta un análisis interdimensional de daños ambientales ocasionados por proyectos palmeros y ganaderos en el Bajo Atrato. El proyecto se desarrolló en dos fases; en la primera, se consolidó la línea base, y en la segunda, se evaluaron los impactos ambientales en tres subfases: identificación de impactos, descripción de impactos por medio del modelo analítico por dimensiones y, por último, valoración y calificación de los impactos. Los resultados del proyecto indican: reducción de la disponibilidad de agua en el ámbito local; alteración de la red de drenaje natural de los suelos y erosión del suelo en riberas del río Curvaradó. Se concluye que los proyectos palmeros y ganaderos son incompatibles con las condiciones agroecológicas de la zona de estudio; y esta conclusión se sustenta en el hecho de que tanto el monocultivo de la palma aceitera como las pasturas exigen suelos en óptimas condiciones inexistentes en la zona, debido al alto contenido de humedad, a menos de que se haga una rigurosa intervención en el medio para responder a los requerimientos de la palma y de las pasturas, lo que tendría enormes impactos sobre los medios natural y humano.

    Full Text Available En el municipio de Puerto Wilches el monocultivo de palma africana actualmente es un eje trasversal de la economía, modificando la diversidad de los ecosistemas y cultivos tradicionales de la zona. Por lo cual, el objetivo de esta investigación es medir y evaluar los impactos de los cultivos de palma africana en el lapso de 1987 a 2010 adaptando la metodología desarrollada por Mathis Wackernagel y William Rees y algunos aportes de los desarrollos realizados por Juan Luis Doménech, aunando a estos tecnología satelital e indicadores de biocapacidad y déficit ecológico para conocer los requerimientos de espacios y recursos naturales necesarios para la producción de los derivados de la palma. El análisis de la época arrojó para el año 1987 un indicador de huella ecológica con un valor de 1.255 ha/pc, biocapacidad del cultivo 0.470 ha/pc, déficit ecológico correspondiente a -0.785 ha/pc; se estima un valor del 16 % en cuanto a la producción y uso de recursos. Con relación a los indicadores de sostenibilidad, en 2010 se obtuvieron valores de huella ecológica de 5.492 ha/pc, biocapacidad 1.454 ha/pc y déficit ecológico de -4.038 ha/pc, cifras que evidencian los efectos originados por la implementación del monocultivo en la zona, que para la fecha aumento en un 63 % la producción y uso de recursos naturales. Por lo anterior, es necesario y urgente elaborar e implementar políticas de planificación territorial así como alternativas de producción económica para mejorar la calidad ambiental y social del municipio, deteniendo la acelerada antropización de la región.

    Full Text Available Introducción: los esteroles han sido ampliamente estudiados por su importancia nutricional y farmacéutica. Sin embargo, para nuestro conocimiento, la composición de esteroles del aceite de los frutos de la palma real cubana (Roystonea regia no ha sido determinada hasta el momento. Objetivos: determinar la composición de esteroles que pudieran estar presentes en la fracción insaponificable del aceite de R. regia mediante CG-EM. Métodos: muestras de dos lotes de aceite de R. regia fueron sometidas al procedimiento para la determinación de esteroles establecido por el del Instituto de Nutracéuticos de los EE.UU., el cual consiste, fundamentalmente, en una saponificación con disolución de KOH/EtOH y posterior extracción con n-hexano de las fracciones insaponificables. Las fracciones obtenidas fueron analizadas por CG-EM como derivados TMS e identificadas por comparación de sus espectros con los de patrones comerciales y los de la base de espectros Wiley. Para la cuantificación se utilizó el colestano como patrón interno. Resultados: en la fracción insaponificable del aceite de R. regia se encontró un contenido total de esteroles de 66,1%; lo que representa un 0,14 % del aceite. La fracción de esteroles, estuvo compuesta principalmente por â -sitosterol (51,2 %, estigmasterol (9,6 %, campesterol (9,2 %, 24-metilen-cicloartanol (9,2 %, Ä5-avenasterol (8,9 %, cicloartanol (7,5 %; además de otros componentes minoritarios como cicloartenol, ã-sitosterol y colesterol. Conclusiones: se identificaron y se cuantificaron mediante CG-EM los esteroles de la fracción insaponificable del aceite de R. regia, en la cual el â-sitosterol resultó el componente mayoritario. Estos resultados son una contribución al estudio de la composición química de dicho aceite y pudieran avalar su posible utilidad nutricional y seguridad.Introduction: sterols have been widely studied because of their pharmaceutical and nutritional importance.

    Full Text Available Se propone una metodología para la valoración de las relaciones entre la ciudad, el turismo y la planificación del territorio desde la perspectiva del paisaje y el medio ambiente. Para ello, analizamos como las estrategias de mejora de la competitividad turística de las ciudades tienen su traslación en la planificación urbanística de los ayuntamientos y la relación o integración de los elementos que configuran ambientalmente el espacio urbano. Con este objeto genérico, se selecciona el ejemplo de Las Palmas de Gran Canaria como laboratorio de experiencias de ordenación del espacio, mediante las cuales puede observarse los indicadores y dificultades en el tratamiento de la calidad ambiental. Nos interesa distinguir cómo estos elementos ambientales se planifican como recursos turísticos y la relevancia que tienen en las estrategias públicas de la ordenación del territorio.A methodology is proposed to asses the relations among the city, tourism, and spatial planning from landscape and environmental perspective. To do this, we analyse how strategies to improve touristic competitiveness in the cities can be applied to spatial planning. To this end, the example of Las Palmas de Gran Canaria is selected, as a laboratory of spatial planning experiences, by which the indicators and difficulties in the environmental quality can be observed. We are interested in distinguishing how this environmental elements are planned as tourism resources and their level of importance in spatial planning.

    Full Text Available En zonas bajas tropicales, en bosques continuos y relativamente poco intervenidos, los frutos de la palma Oenocarpus bataua Mart., son consumidos por diversas especies de vertebrados, sin embargo, no hay estudios de dispersión de más largo plazo con esta especie. Entre agosto 2005-septiembre 2006 se realizaron observaciones de remoción de frutos, conteo de frutos comidos, observaciones focales, registros de frugivoría mediante trampas fotográficas, experimentos de dispersión y parcelas para determinar distribución espacial de Oenocarpus bataua. Cinco especies de mamíferos comen, dispersan, entierran (Sciurus granatensis, Microsciurus mimulus, Dasyprocta punctata y Proechimys sp., tapan (Marmosa robinsoni y llevan a las cuevas (Marmosa robinsoni y Proechimys sp., los frutos de O. bataua, sin dañar la semilla. El 21.7% de los frutos fueron dispersados, 13.2% roídos o pelados, 5.6% tapados, enterrados y llevados a cuevas. La distancia media de remoción de semillas y frutos fue 3.1m, aunque en menor proporción se registraron eventos de dispersión > a 50m. La abundante producción, el tamaño, el peso, la intensa remoción de los frutos por frugívoros, las cortas distancias de dispersión, la ausencia de frugívoros de gran porte disminuidos por cacería y fragmentación, encargados de la dispersión de larga distancia y el aumento de roedores, especialmente ardillas que presionan fuertemente el recurso frutos, generan una lluvia de semillas espacialmente restringida, posiblemente responsable de los patrones de distribución agregados en semillas, plántulas y posteriormente en juveniles y sub-adultos.Seed dispersal is a key process that determines the spatial structure and dynamics of populations of plants, establishes the potential area of recruitment and in this way, the basis for subsequent processes such as predation, germination, competition and growth. The purpose of this research was to identify the guild of frugivores of the

    Full Text Available OBJETIVO: Comparar, em ratos jovens, os efeitos metabólicos de dietas distintas, à base de óleo de palma e de gordura hidrogenada. MÉTODOS: Ratas Wistar receberam dietas com diferentes fontes lipídicas durante a lactação, as quais continuaram a ser dadas aos filhotes machos do 21º dia ao 45º dia de vida, após ajuste às recomendações da American Institute of Nutrition-93, quando estes foram decapitados. Os tecidos adiposos epididimal e perirrenal foram retirados para determinação da taxa de lipogênese in vivo com ³H2O e, no plasma, avaliou-se o perfil de ácidos graxos por cromatografia gasosa, além da concentração dos triacilgliceróis e colesterol total, por meio de kits enzimáticos. RESULTADOS: A substituição, na dieta, da gordura hidrogenada pelo óleo de palma aumentou, no plasma, a proporção do ácido graxo araquidônico e diminuiu a proporção do ácido essencial linolênico e a concentração dos triacilgliceróis e colesterol. Elevou o conteúdo lipídico e a taxa lipogênica do epidídimo e perirenal, repercutindo em maior peso corporal, bem como na adiposidade nesses animais. CONCLUSÃO: O tipo de ácido graxo oferecido na dieta desde o período da lactação, pode influenciar o metabolismo lipídico do tecido adiposo na idade jovem, bem como o comportamento alimentar e ganho de peso corporal, com possíveis repercussões para o desenvolvimento de doenças crônicas não transmissíveis.OBJECTIVE: To compare the metabolic effects of diets based on palm oil and hydrogenated fat on young rats. METHODS: Wistar female rats, during lactation, were fed diets with different lipid sources, which were also adjusted to the recommendations (American Institute of Nutrition-93 and given to the male pups from the 21rst day to the 45th day of life, when they were killed. The epididimal and perirenal adipose tissues were extracted and had their lipogenesis rates measured in vivo with ³H2O. We also measured, in the plasma

    Full Text Available This study evaluated the sequential motor manual actions in children with benign focal epilepsy of childhood with centrotemporal spikes (BECTS and compares the results with matched control group, through the application of Luria's fist-edge-palm test. The children with BECTS underwent interictal single photon emission computed tomography (SPECT and School Performance Test (SPT. Significant difference occurred between the study and control groups for manual motor action through three equal and three different movements. Children with lower school performance had higher error rate in the imitation of hand gestures. Another factor significantly associated with the failure was the abnormality in SPECT. Children with BECTS showed abnormalities in the test that evaluated manual motor programming/planning. This study may suggest that the functional changes related to epileptiform activity in rolandic region interfere with the executive function in children with BECTS.Esse estudo avaliou ações motoras manuais sequenciais em crianças com epilepsia focal benigna da infância com descarga centrotemporal (EBICT e comparou os resultados com o grupo controle pareado, através do teste de Lúria (punho-lado-palma.

    Full Text Available Several palms species provide an important habitat for triatomines and associate vertebrates in tropical America. The objective of this work is to identify the triatomine species living in the palms of rural areas in the Province of Corrientes, and to estimate the potential epidemiological risk they represent for the residents of nearby houses. The survey was carried out in a palm community in Colonia Laurel, Department San Roque, Province of Corrientes, Argentina. Samplings were performed in October, November and December 1998; January, February and March 1999; May and June 1999. Thirty palms: 27 (90% Butia yatay (Mart. Becc. and 3 Acrocomia aculeata (Jacq. Lodd ex Mart. were dissected. Triatoma sordida Stål 1859 was found in 96.2% of B. yatay and in all the A. aculeata palms. A total of 272 live T. sordida was collected; 36 of them (13.2% were found in bird nests in the frond and the remainder in other locations of the tree. The mean number of triatomines per palm was 9.6 (range 1-60, mode 2. T. sordida was collected during all the sampling months and all stages were present at all seasons. The highest population density was reached in spring and the lowest in autumn. Trypanosoma cruzi was detected in 38.5% in feces of 174 examined insects and identified as such, both by microscopical examination and PCR. This is the first finding of T. sordida populations in B. yatay, an endemic palm of South America distributed in southern Brazil, Uruguay and northeastern Argentina. The high infection prevalence found in this work suggests that T. sordida plays an essential role in the maintenance of the wild T. cruzi transmission cycle in northeastern Argentina.

    Full Text Available ABSTRACT Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differences on nesting between interior and edge transects. A sum of 1,500 trap nests was made with bamboo cane internodes and two consecutive years were monitored. In the first year 46 nests were occupied by Pachodynerus grandis (19 nests, Pachodynerus guadulpensis (19, Centris analis (two, and Centris tarsata, Megachile fiebrigi, Megachile guaranitica, Megachile susurrans, Trypoxylon sp and Zethus smithii with one nest each. No statistical differences were found between interior and edge transects for richness and occupation rate, but the species composition was different. In the second year 39 nests were occupied by four species, three previously recorded, C. analis (seven nests, P. guadulpensis and P. grandis (six nests each, plus Monobia angulosa with 15 nests. Parasitoids from four families and one cleptoparasite were recorded and the mortality rate was higher in bees than in wasps. These findings reinforce the notion that trap nests assemblages from different studies are not directly comparable for richness and composition.

    The increasing demand for safe food without preservatives or pesticides residues has encouraged several studies on natural products with antifungal activity and low toxicity. In this study, ethanolic extracts from leaves and fruit residues (peel and seeds) of three Brazilian savanna species (Acrocomia aculeata, Campomanesia adamantium and Caryocar brasiliense) were evaluated against phytopathogenic fungi. Additionally, the most active extract was chemically characterized by ESI-MS and its oral acute toxicity was evaluated. Extracts from C. brasiliense (pequi) peel and leaves were active against Alternaria alternata, Alternaria solani and Venturia pirina with minimal inhibitory concentrations between 350 and 1000 µg/mL. When incorporated in solid media, these extracts extended the lag phase of A. alternata and A. solani and reduced the growth rate of A. solani. Pequi peel extract showed better antifungal activity and their ESI-MS analysis revealed the presence of substances widely reported as antifungal such as gallic acid, quinic acid, ellagic acid, glucogalin and corilagin. The oral acute toxicity was relatively low, being considered safe for use as a potential natural fungicide.

    Full Text Available This work reports on a very effective route to produce bio-based polyurethanes (PUs and composites with high content of renewable carbon sources. The PUs are prepared with polyols synthesized from macauba oil (Acrocomia aculeata and methylene diphenyl diisocyanate, at different [NCO]/[OH] molar ratios. Later, biocomposites are prepared with the as-obtained PUs reinforced with coconut husk fibers. The successful synthesis of natural oil-based polyols is ascribed to the hydroxylation and consumption of carbon-carbon double bonds in the fatty acid chains of the original starting oil as attested by FTIR spectroscopy. According to different thermal analysis techniques (TG, DTG, and DTA, the increase in the [NCO]/[OH] molar ratio improves the thermal stability of PUs, likely due to an increase of crosslinks. Dynamic mechanical analysis evidences the reinforcement effect of coconut husk fibers in bio-based PUs. The present PUs and composites are of low-cost and environmentally friendly materials for structural applications.

    For development of a productive activity, with reduced environmental degradation, the use of renewable energy sources as an important option. The gasification has been increasing among the ways of obtaining energy from biomass, and consists of a process where the necessary oxygen to the complete combustion of a fuel it is restricts and, in high temperatures it generates fuel gas of high-quality. In this direction, this work is justified and has its importance as the study of a renewable energy source, macauba coconut (Acrocomia aculeata [Jacq] Lodd), with the gasification process. The objective of this study is to build a biomass concurrent gasifier and evaluate the viability to provide heating for dehydration of fruits, using the macauba coconut as fuel. It was measured the temperature in five points distributed in both gasifier and combustor chamber, being the input area of primary combustor air and also the speed of rotation of the electric motor, using a factorial 3X3 experimental design with three repetitions and interval of measurements of five minutes. The analytical results take to infer that the macauba coconut have potential to be gasified and used for the dehydration of fruits. (author)

    Full Text Available The fruit of the native macaw palm [Acrocomia aculeata (lacq Lood. ex Mart] is an alternative for biodiesel production because of the plant characteristics, as well as its adaptability, hardiness and high vegetable oil yield. However, its exploitation remains extractive and there are significant difficulties in its harvest. This study aimed to determine the mechanical properties of the macaw palm fruit-rachilla system that will support the design of harvest machines based on mechanical vibration. Ten samples of four accessions in the immature and mature stages of maturity were used. Traction and vibration tests were conducted to determine the mechanical properties of the macaw palm fruit-rachilla system. The elastic modulus of the rachilla was 188.39-385.09 MPa for the immature stage and 109.02-320.54 MPa for the mature stage. The Poisson's ratio for the rachilla varied between 0.20 and 0.52 for the immature stage and between 0.16 and 0.52 for the mature stage. The damping ratio varied between 0.02 and 0.12 for the immature stage and between 0.06 and 0.12 for the mature stage. The fruit-rachilla system was characterized as underdamped.

  5. Macauba: a promising tropical palm for the production of vegetable oil

    Full Text Available The growing global demand for vegetable oils for food and for replacing fossil fuels leads to increased oilseeds production. Almost 122 of the current 187 million tons of vegetable oils produced in the world correspond to palm and soybean oils. The oil palm is cultivated in the tropical zone, in areas formerly occupied by forests, and soybean oil is a by-product of protein meal production. The diversification of raw materials for the vegetable oil market is thus strategic for both food and non-food sectors. Sources for vegetable oil should be economically competitive and provide sustainability indexes higher than that provided by oil palm and soybean. In this context, we describe the potential of Acrocomia aculeata, popularly known as macauba. Macauba is an American palm from the tropical zones which presents oil productivity and quality similar to that of the oil palm. It grows spontaneously in a wide range of environments and it is not very water demanding. Macauba palm has a high potential for oil production and for diversification of co-products with some potential of value aggregation. Such a perennial and sustainable species will probably fulfill the requirements to become an important new commercial oilseed crop.

O objetivo deste trabalho foi verificar a distribuição estereoespecífica dos ácidos graxos nos lipídios estruturados. Foi possível comprovar a ocorrência da interesterificação através da hidrólise enzimática, que permitiu conhecer a composição dos ácidos graxos em posições específicas dos triacilgliceróis. Foram estudadas 10 amostras, representadas por 3 amostras individuais, 3 misturas binárias e 4 misturas ternárias. As amostras foram submetidas à hidrólise com lipase pancreática suína à temperatura de 40 ºC e posteriormente analisadas por cromatografia gasosa quanto à composição em ácidos graxos na posição sn-2. A partir dos resultados foram calculados os grupos de triacilgliceróis nas amostras individuais e nas misturas antes e após a reação de interesterificação, utilizando as teorias 1,3-random 2-random e 1,2,3-random. Os resultados demonstraram que antes do rearranjo ao acaso houve preferência do ácido oléico pela posição sn-2, enquanto que os ácidos palmítico e esteárico distribuíram-se principalmente pelas posições sn-1 e sn-3. Nos lipídios estruturados, os ácidos graxos saturados aumentaram sua participação na posição central do triacilglicerol, enquanto que os ácidos graxos insaturados apresentaram diminuição nesta mesma posição.Structured lipids were synthesized by chemical interesterification from palm oil, palm kernel oil, and medium chain triacylglycerols.

    The objective of the current study was to develop parameters for the separation of palmitic acid (PA) from a crude palm oil saturated fatty acid (SFAs) mixture by using the methanol crystallization method. The conditions of methanol crystallization were optimized by the response surface methodology (RSM) with the D-optimal design. The procedure of developing the solvent crystallization method was based on various different parameters. The fatty acid composition was carried out using a gas chromatography flame ionization detector (GC-FID) as fatty acid methyl esters. The highest percentage of SFAs was more than 96% with the percentage yield of 87.5% under the optimal conditions of fatty acids-to-methanol ratio of 1: 20 (w/v), the crystallization temperature of -15 °C, and the crystallization time of 24 hours, respectively. The composition of separated SFAs in the solid fraction contains 96.7% of palmitic acid (C16:0) as a dominant component and 3.3% of stearic acid (C18:0). The results showed that utilizing methanol as a crystallization solvent is recommended because of its high efficiency, low cost, stability, availability, comparative ease of recovery and its ability to form needle-like crystals which have good filtering and washing characteristics.

Standing herbage biomass (HB harvesting and Photosynthetic active radiation (PAR readings were taken at three different periods in a paired sample scheme. Of the six tree species studied, Enterolobium cyclocarpum had the largest mean crown cover while Acrocomia aculeata had the smallest. Significant differences were observed between species (P = 0.0002 and seasons (P<0.008 for the percentage of PAR transmitted under the canopy but PAR levels obtained under all species were consistent throughout seasons since the interaction between species and season was not significantly different (P=0.98. Lower PAR readings (<50% were taken under the canopies E. cyclocarpum and Guazuma ulmifolia (21.7 and 33.7 % respectively. Standing herbage biomass (SHB harvested under the crown of isolated mature individual tree species was significantly lower (P<0.001 than in open pasture areas for all tree species except that of A. aculeate but SHB crude protein content, was higher underneath all tree canopies. It can conclude that light reduction caused by tree canopies reduces SHB availability and increases the quality underneath tree canopies compared to areas of full sun but these varies accordingly to tree species and seasons.

    Full Text Available Understanding the effect of habitat fragmentation is a fundamental yet complicated aim of many ecological studies. Beni savanna is a naturally fragmented forest habitat, where forest islands exhibit variation in resources and threats. To understand how the availability of resources and threats affect the use of forest islands by parrots, we applied occupancy modeling to quantify use and detection probabilities for 12 parrot species on 60 forest islands. The presence of urucuri (Attalea phalerata and macaw (Acrocomia aculeata palms, the number of tree cavities on the islands, and the presence of selective logging,and fire were included as covariates associated with availability of resources and threats. The model-selection analysis indicated that both resources and threats variables explained the use of forest islands by parrots. For most species, the best models confirmed predictions. The number of cavities was positively associated with use of forest islands by 11 species. The area of the island and the presence of macaw palm showed a positive association with the probability of use by seven and five species, respectively, while selective logging and fire showed a negative association with five and six species, respectively. The Blue-throated Macaw (Ara glaucogularis, the critically endangered parrot species endemic to our study area, was the only species that showed a negative association with both threats. Monitoring continues to be essential to evaluate conservation and management actions of parrot populations. Understanding of how species are using this natural fragmented habitat will help determine which fragments should be preserved and which conservation actions are needed.

The crude extract and one of the fractions rich in catechin also showed inhibitory activity against acyclovir-resistant herpes simplex virus type 1 (HSV-1-ACVr). All fractions were inactive against the fungi Candida albicans, Fonsecaea pedrosoi and Cryptococcus neoformans. Catechin and epicatechin together with condensed tannins (B-type procyanidins) were demonstrated to be the components of the water extract.

    Cocos nucifera cultivated in Brazil is known as "coco-da-Bahia" or "coqueiro-da-India". The tea from the husk fiber is widely used to several inflammatory disorders. Crude extract and fractions obtained from Cocos nucifera "common variety" were evaluated to test the anti-inflammatory and antinociceptive activities. Crude extract (CE, 50, 100, and 150 mg/kg), fraction 1 (F1, molecular weight lesser than 1 kDa, 1, 10, and 50mg/kg), fraction 2 (F2, molecular weight higher than 1 kDa, 1, 10, and 50mg/kg), and the references drugs morphine (5mg/kg), acetilsalicilic acid (200mg/kg), prometazine (30 mg/kg), and metisergide (5mg/kg) were evaluated on models of analgesia and inflammation. CE, F1, and F2 significantly develop peripheral and central antinociceptive activity but with less effect on supra-spinal regions of the brain. Administration of the opioid antagonist, naloxone (5mg/kg) inhibited the antinociceptive effect indicating that Cocos nucifera crude extract and fractions may be acting in opioid receptors. CE and F1 also inhibited rat paw edema induced by histamine, and serotonin. results demonstrated that Cocos nucifera and its fractions have antinociceptive and anti-inflammatory activities which confirm the popular use of this plant in several inflammatory disorders.

    The present study aims to determine the antioxidant capacity of the ethanolic extracts of husk fiber of four coconut (Cocos nucifera L.) varieties (yellow dwarf, green dwarf, giant and hybrid) and to evaluate the electrochemical behavior of these extracts on a glassy carbon electrode and on a modified glassy carbon electrode. The highest values of total phenolic content were obtained for the hybrid (531 ± 24 mg GAE g(-1) dry extract) and yellow dwarf (501 ± 29 mg GAE g(-1) dry extract) varieties and the lowest was for the green dwarf variety with 58 ± 9 mg GAE g(-1) dry extract. The ability of the extracts to scavenge DPPH˙ radicals was in the order of giant > yellow dwarf > hybrid > green dwarf and the IC50 values varied from 8.6 to 55.9 μg mL(-1). All varieties showed reducing potential by the use of FRAP and CUPRAC methods, with the lowest performance obtained for the green dwarf variety. Additionally, through the use of mimetic biomembranes, ethanolic extracts of coconut husk were shown to protect lipids against oxidative damage independent of the variety. The main antioxidants identified in the extract of yellow dwarf variety by UPLC-MS were quercetin and catechin. Cyclic voltammetric studies of the ethanolic extracts on glassy carbon electrode confirmed the presence of easily oxidized compounds, and the high antioxidant capacity of the varieties. This capacity was expressed as mg quercetin equivalents g(-1) dry extract and ranged from 25.9 up to 53.5 mg QE g(-1). A poly-xanthurenic acid (poly-Xa)/multi-walled carbon nanotube (MWCNT) / glassy carbon modified electrode (poly-Xa/MWCNT/GCE) was used for this purpose. Our findings suggest that these extracts are potentially important antioxidant supplements for the everyday human diet, pharmaceutical and cosmetic industries, thereby aggregating value to the enormous amount of waste from the coconut industry, mostly used for burning purposes.

    The town of Macachin is located over the Valle Argentino aquifer. there, the phreatic aquifer is lodged in a sandy superficial cap and in the slime-sandy sediments. The objective of this work is to depict the pollution of the unconfined aquifer of Macachin, considering the presence of nitrate as determining actor of the quality of the resource. The peri urban area was analysed with the purpose of cover the area of relocalization of the sources of potable water for the town. In the urban area, the domiciliary perforations and in those os supply were considered. Samples in perforations and in drilled wells were collected. Temperature, pH, electrical conductivity and the ions concentration for nitrate and chloride were measured. Statistical basic parameters were calculated for eight wells in exploitation and also for the perforations and drilled wells. It was concluded that the conditions of the underground waters is little satisfactory. All of the domiciliary wells sampled contained a quantity of nitrate that overcomes the maximum levels allowed for the consumption of potable water. In the city's wells of supply a significant increase of the nitrate concentrations was identified since 1998, approximately. The contribution of organic matter to the underground water could be originated in the decomposition of the domiciliary wastes arranged in cesspools. In both areas, the nitrate concentrations in the unsaturated zone are similar and superior to the limit allowed for human consumption. The pollution sources in the rural zone can be permanent corrals of animals. (Author) 10 refs.

    Biochar (BC) is a carbon-rich product obtained when biomass is thermally decomposed at relatively low temperatures (under 700°C) and limited supply of oxygen in a process called pyrolysis. The conversion of biomass into BC can not only result in renewable energy source of synthetic gas and bio-oil, but also decrease the content of CO 2 in the atmosphere, as well as improving soil fertility. Because of its porous structure, charged surface and surface functional groups, BC exhibits a great potential as an adsorbent. Brazilian agro energy chain involves tons of biomass waste, providing a wide range of biomass with different chemical and physical properties. BC characteristics strongly depend on the feedstock and the pyrolysis conditions, in which the temperature is the key parameter. The aim of this study was to evaluate the adsorption potential for the removal of uranium, U(VI), from aqueous solutions using BC obtained through the pyrolysis of the Macauba (Acrocomia aculeata) coconut endocarp as a function of the final pyrolytic temperature. BCs produced at higher temperatures are likely to present lower H/C and O/C ratios, indicating the loss of easily degradable carbon compounds such as volatile matter. In contrast, low-temperature pyrolysis produces not only a higher BC yield, but also richer in surface functional groups which will likely enable interactions with the U(VI) ions. The endocarp was subjected to six different pyrolytic temperatures, ranging from 250°C to 750 °C. The influence of parameters such as pH, sorbent dose and initial concentration on the adsorption of U(VI) was investigated. The maximum adsorption capacity (q) was achieved for the BC obtained at 250°C (BC250), which presented a removal percentage of approx. 86%, demonstrating the potential of the BC from macauba endocarp for treatment of wastewaters. Thus, submitting the endocarp to temperatures higher than 250°C becomes unnecessary, saving time and reducing operating costs. (author)

    Full Text Available Macauba palm coconuts are rich in essential nutrients for animal feed formulation and after oil extraction, a large amount of residual biomass is produced, which must be used rationally to environmental preservation. This study aimed to determine the nutritional value of macauba palm (Acrocomia aculeata, cake and leaves, for its physical and chemical composition, dry matter (DM in vitro digestibility (IVD and in situ degradability. The test of in situ degradability was done using three rumen fistulated cattle. Analytical determinations were performed in the laboratory of Animal Nutrition of Instituto de Zootecnia, Nova Odessa-SP, Brazil. Six replicates were used for each analytical determination and were calculated the standard error. Macauba cake chemically assessed showed a low protein content (CP 4.5% and high content of acid detergent fibre (ADF 39.7% and average levels of neutral detergent fibre (NDF 52.5%. ADF and NDF were the macauba palm cake majority fractions compared NDF and ADF (respectively of cocoa cake (37.6 and 45.5%, sunflower cake (28.2 and 38.4%, corn meal (11.3 and 20.2% and peanut cake (15.4 and 21.0. Macauba palm leaves had a good protein content (12.0% and fiber content comparable to tropical grass of good nutritional value. They can be used with no restriction on ruminants’ diets. The macauba palm cake high levels of lignin (16.5% justify the low dry matter IVD percentage (48%, while the leaves had 58%.of IVD. Macauba leaves total digestible nutrients (TDN 59.0% is similar to TDN usually observed for forages. Macauba cake can be considered (TDN = 64.0% similar to energetic food, due to the fat content (6.4%, however the high content of lignin (16.5% can limit its consumption. Macauba palm cake showed high ruminal degradability of DM and CP (fraction a = 51.3 and 59.9, respectively, while macauba palm leaves hah low solubility of DM and CP (fraction a = 3.18 and 5.28, respectively.

    There are no simple procedures to estimate the bearing capacity of direct foundations on rock due to its anisotropy, as the criteria have to take into account different features concerning the rock discontinuities (spacing, orientation, opening, persistence,...) as well as other aspects concerning the rock matrix, particularly its strength when it is low. In this sense, the volcanic formations of the Canary Island pose important difficulties to the designer of foundations given their highly anisotropic fabric, which is the result of a complex origin where the basalt sheets alternate with fragmentary material of pyroclastic nature. This volcanic building is frequently intersected by old vents, in the guise of pipes plugged with broken fragments of low compacity. In a valley of highly dissected steep slopes of such geology an arch bridge has been designed and built with a span between supports of 250 m. This paper describes the analysis that was carried out to take into account the particularities of rock anisotropy and the foundations geometry in very steep slopes. The construction problems are also addressed in the paper, describing the grouting treatment that was needed in one of the supports due to the presence of an old vent. (Author) 7 refs.

    Full Text Available We present a range of observations on the reproductive morphology, pollination biology and cultivation of Lodoicea maldivica (coco de mer, an endangered species with great ecological, economic and cultural importance. We review the history of study of this charismatic species. Morphological studies of the male inflorescence indicate its importance as a year-round food source to the Seychelles fauna. In situ observations suggest a number of potential biotic and abiotic pollination mechanisms including bees, flies, slugs, and geckos; trigonid bees are identified as the most likely potential natural pollinator. We outline a successful programme for ex situ pollination, germination, and cultivation of the coco de mer, highlighting the importance of temperature, humidity and light levels as well as maintaining an undisturbed environment. In combination with continued protection and monitoring, this advice may aid the future in situ and ex situ conservation of the coco de mer.

The isozymes are biochemical markers of importance in the study of genetic variability in plants of economic importance, because they are the primary products of genetic expression. This work is an electrophoretic analysis on gels of polyacrilamide to study phenetic relations using twelve isozymes on four races and an spontaneous hybrid of peach palm. The biological material used came from the germplasm bank from Los Diamantes Experimental Station, Guápiles-Costa Rica. Four races and a hybrid were selected from that collection. They represented different procedences with morphological differences as well as having particular geographical distribution patterns; they were: Tembé-Chapare (Bolivia-Bo, Pará -Belem (Brasil-Bra, Utilis Guápiles (Costa Rica-CR, Tuira-Darién (Panamá-Pa and Yurimaguas (Perú-Pe. Five trees of each race and the Yurimaguas hybrid were studied. Different tissues were tried: leaf, adventitious roots, spines, masculine flowers and ripe fruits. An standard native and discontinued method was established on a polyacrilamide matrix for the analysis of twelve isozymes: (PRX, EST, ACP, DIA, G6PDH, ME, MDH, GOT, ADH, PGI, PGM and SOD. The amount of tissue used was 1. 5 g, with 20 min clarification time at 15000 gravity value and a temperature of 4°C. The protocol proposed by Baaziz & Saaidi (1988 was followed with a modification of concentration of the phosphate buffer solution from 0,005 M to 0. 1M with a 50 to 200 volts gradient. The root, flower and spine tissue were difficult to homogenize because of their high fiber content. The fruit has too much oil and starch, which distort the banding. For those reasons they were discarted. The leaves were selected because they are easy to homogenize and are available all year round. The standardized electrophoretic method allowed the effective use of ten of the twelve isozymes in the leaf tissue. Those ten isozymes showed phenetic polymorphism and are considered useful polymorphic markers for genetic and phenetic diversity studies in Bactris gasipaes. A discriminant marker for the Utilis-Guápiles race was found with the PRX isozyme, which shows an additional locus only in material from that procedence. The conglomerate statistical analysis showed that the races and hybrid studies can be placed in three groups: one is formed by Par and Tembé, the second one by Utilis and Tuira, and the hybrid Yurimaguas is a class by itself and although it seems a bit closer to Utilis-Tuira, it is suspected that has its origin from unknown parents. These results fit previous morphological interpretations. A genetic analysis was not made because of the small sample size, but methodological procedures were established for future research projects using larger populations to study peach palm isozyme electrophoretic diversity.

    The congress intends to translate fundamental knowledge on the microbial ecology of impaired ecosystems into technological solutions for the restoration of terrestrial and aquatic environments. The unification of fundamental and applied research is of utmost importance because they are interdependent and connected to the action-reaction of the environment. Then the main objective of the congress will be to integrate the different technology oriented research engineering, biotechnology) in such a way that their future action will be based on fundamental research (ecology). The action on the environment must be interactive with the participation of different disciplines having common objectives: -One of the common objectives must be to preserve energy resources and create renewable ones. -Other common objectives must be the re-use of waste which should be valorized and not seen any more as waste but better as new resources- -Finally, the last but not the least common objective must be to minimize pollution and discharge to the environment in order to protect its ecology. All this will be achieved only with the development of cleaner and cheaper technologies both on an environmental and an energy point of view as well as with an adequate environmental education and a sustainable development.

    Full Text Available El hospital de San Martín fue una de las principales instituciones asistenciales de las islas durante todo el Antiguo Régimen. Sus cortos ingresos fueron sostenidos por las rentas procedentes de los bienes de su fundación, por las aportaciones del Cabildo Catedral, del obispo, las limosnas de los vecinos y la de los acogidos, aunque siempre su economía estuvo en precario ante la gran cantidad media de asilados. Los enfermos estaban integrados en un amplio porcentaje por miembros de las capas populares —libertos, pobres mendicantes, pequeños artesanos, marineros, viudas, mujeres abandonadas— cuyas enfermedades básicas eran la pobreza, la marginalidad y la vejez. La entidad fue, ante todo, un centro en el que el grupo de poder distribuyó una mínima parte de las ingentes ganancias percibidas a través de la explotación de los sectores populares, buscando a cambio el mantenimiento de sus intereses con el control de dicha población, presentarse ante ellos como sus benefactores y la compra, si era posible, del perdón eterno.Saint Martin’s Hospital was one of the major care institutions in the Canary Islands throughout the Acient Regimen. Its scarce income was sustained thanks to the revenues, which came from the assets of its foundation, the contributions made by the Board of the Cathedral, the bishop, the donations by the neighbours and those made by the patients, although its finances were always precarious due to the great number of residents sheltered there on average. A high percentage of the patients were mainly members of the lower classes —freemen (ex-slaves, beggars, craftsmen, sailors, widows, abandoned women— whose sufferings were mainly poverty, marginality and old age. This institution was, above all, a body in which the power groups invested a minimum part of the huge income obtained through the exploitation of the popular sectors of society, whose aims were the maintenance of their interests through the exertion of total control over such population, therefore presenting themselves with the image of benefactors, and the purchase, if possible, of the eternal blessings.

    Somatic embryogenesis (SE is an in vitro developmental pathway that exhibits a number of advantages over other techniques for regeneration of palms. This technique has great potential to overcome the limitations observed when trying to propagate these plants clonally using basal buds. Despite the known recalcitrance of palms for in vitro culture, good results can be obtained by using the appropriate growth regulators, explant type and developmental stage, as well as responsive genotypes. This has been partially observed in Phoenix dactylifera (date palm, Elaeis guineensis (African oil palm, Bactris gasipaes (peach palm and Cocos nucifera (coconut. Efficient protocols have been also generated in less-studied palms, such as Geonoma gamiova (an ornamental palm, Euterpe edulis (Assai palm and Areca catechu (areca palm. Induction of  SE has been achieved mainly through the use of auxins. Of these, 2,4-dichlorophenoxyacetic acid (2,4-D has been used most frequently, although in some cases (such as in peach palm and African oil palm picloram and dicamba have been employed also with good results. The most commonly used explants are young inflorescences, apical buds and leaf-basal segments. Explant size and culture medium also play an important role in obtaining good results. This review presents a compilation of the most important publications on SE in this plant family and the effect of various factors on induction and development of this pathway. Key words: Culture medium; explants; genotype; plant growth regulators; regeneration

    Full Text Available This article describes the mechanisms through which the transition from banana to oil palm plantations in Zona Bananera, Magdalena, has been influential in forced displacement. Therefore it adds to the debate about the paths between resources and conflict in the literature on political economy of internal armed conflicts. The outcome of this qualitative research suggests that in the case in question the following “pathways” have operated: 1. The absence of a strong institutional presence has permitted the collection of extortions by illegal armed groups allowing their financing and generating forced displacement as a consequence of the threats; 2. The transition from banana to palm extraction reduced the intensity of manual labor and food security unleashing displacement processes; and 3. The institutional incentives for oil palm exploitation have promoted the usurpation of land by illegal armed actors who provoke the displacement in order to acquire land for their cultivation.

    The production of biodiesel has seen a fast growth in Brazil during the last years, making the country one of the top producers in the world. This growth is explained by the mandatory blendings of biodiesel in conventional diesel. This article is about how the biodiesel industry developed having soy oil as the main feedstock and how the big oilseed crushers have taken the main role in the industry, with family farmers, the original beneficiaries of the program, having a marginal role. If the scenario of B10 or B20 in 2020 is verified, then it is going to use so much soy oil that it will interfere in another uses of soy, like exportation. Besides that, the article criticizes the failure of the social aspect of the program, arguing that the objective of integration of family farmers has failed, and that the numbers are not worse only because the action of the government, through PETROBRAS. Then it is presented the palm oil as a alternative to share the role of main feedstock with the soy oil, because palm has a bigger production of vegetal oil per hectare than most oilseeds, is capable of a bigger reduction in green house gas emissions than soy oil, the fact that Brazil has plenty of land available to plant palm, without the necessity of deforestation and that this process can bring development to family farmers in the north of the country. The article ends with the summary of the main projects of palm production for biodiesel, like the ones from PETROBRAS, Vale and Oleoplan, and how these are going to be the main determinants of the success or failure of the palm oil as an alternative to the biodiesel sector.

The numerous conditioning factors which limited the construction of the hall from the beginning, both regarding the surface —rectangular and extremely elongated, messuring 13 x 13 m, and height— about 3 m, and regarding its situation within the whole, lead to the arrangement of three articulated atmospheres within a single space, covered with thin reinforced concrete warped membranes, as the only solution capable, on the one hand, of reducing the coldness and stiffness of the structure imposed, and on the other, of satisfactorily answering the design bases which prefixed multifunctionality, transparency and representativity of the building. A final premiss which called for the integration of the work in a surrounding gardaned environment was solved by the complete glazing of the frontages and the light tones of the finishing materials.

    Este salón es la primera fase de un ambicioso programa de reformas y ampliaciones para el Club Natación Metropole que, además de aumentar y diversificar el número de las instalaciones deportivas, incluye otras de carácter eminentemente social. Los numerosos condicionantes que desde un principio limitaron la construcción del salón, tanto en cuanto a superficie —rectángulo sumamente alargado de 13 x 33 m— y altura —unos 3 m—, como a su situación dentro del conjunto, condujeron a la organización de tres ambientes articulados dentro de un espacio único, cubiertos con sendas membranas delgadas de hormigón armado, de formas alabeadas, como única solución capaz, por una parte, de reducir la frialdad y rigidez de la conformación impuesta, y por otra, de responder satisfactoriamente a las bases de diseño que prefijaban la multifuncionalidad, diafanidad y representatividad del edificio.

    Full Text Available Currently, there are two mixtures of biodiesel/diesel fuel sold in Brazil: BX/S500 and BX /S10 (X = volume/volume biodiesel percentage; S500 and S10 = sulfur content in diesel fuels - 500 ppm and 10 ppm, respectively. In order to differentiate these mixtures, red dye is added to diesel oil as required by the National Agency for Petroleum, Natural Gas and Biofuels (ANP, regulatory agency in Brazil. Since the palm oil biodiesel has also a reddish color, mixing this product with diesel fuel leads to difficulty in visual differentiation of the mixtures BX/S500 and BX/S10. We propose the use of UV-Vis spectrophotometry, which is a low cost, simple and rapid technique. Spectra obtained for different mixtures show that qualitative distinction is possible. For quantification of red dye in the presence of palm oil biodiesel, the method is limited when dye is present in low concentrations (< 0.1 mg L-1 due to matrix effects. The method showed good repeatability of the absorbance responses, wide linear dynamic range (0.02 mg L-1 to 40.00 mg L-1 and low limits of detection and quantification (0.006 mg L-1 and 0.019 mg L-1, respectively.

    Full Text Available The objective of this work was to assess field vegetative development of oil palm comercial hibrids up to age of 18 months, in two ecosystems of Roraima. Two essays are being conducted, one of them in area of savanna and the other in deforested area with assessment of commercial hybrids BRS 2528, BRS 3701 and BRS 2301, under experimental design of completely random blocks with six replicates. Monthly measurements, which began 14 months after field planting, took place concerning to number of emitted leaves, width of leaf nr.4 (cm, plant hight (cm and ground level stem diameter (cm. Individual and conjoined variance analysis were performed, considering the effects of hybrids and periods as fixed and the others as aleatory. For comparison of estimated averages of assessed characteristics, Tukey test at level of 5% probability was used. As to detect alterations relative to characteristics during the period of study, concerning each environment, regression equations were estimated, the assessed characteritic being the dependent variable and the measurement epochs being the independent variable. One may conclude that, in deforested areas, hybrids show higher vegetative development than those obtained in savanna; hybrids BRS 2528, BRS 3701 and BRS 2301 showed vegetative development equivalent in savana and hibrid BRS 2301 outstanded from the others in deforested area.

Se ha constituido un banco de datos a partir de las informaciones contenidas en las etiquetas de 2897 muestras de herbario colectadas en el Perú. Éste incluye 33 géneros nativos. Los más colectados son Geonoma, Bactris, Chamaedorea, y Hyospathe. El 73.9 % de los especimenes están determinados a nivel de especie, con un total de 152 taxa. La tasa de determinación varía mucho de un género a otro. Se colectaron palmeras nativas en 47 provincias distribuidas en 14 departamentos. La gran mayoría de las muestras provienen de la Amazonia y de la región subandina. Se ponen en evidencia los lugares de alta diversidad, así como las regiones donde se colectó poco. Finalmente, se discute sobre la eficacia operacional del banco de datos, tomando en cuenta el grado de fiabilidad de las determinaciones a nivel de especie y de los datos geográficos de varias etiquetas, así como la representatividad del muestreo analizado. UPDATING PERUVIAN PALM FLORA - FIRST STEP: COLLECTING INTENSITY AND COLLECTION RICHNESS. Data from labels of 2897 vouchers collected in Peru have been analyzed. The data bank includes 33 native genera. Geonoma, Bactris, Chamaedorea, and Hyospathe are the most collected. Of all the vouchers, 73.9 % are identified at the specific level totaling 152 taxa. Identification rate is relatively high in some genera and low in others. Native palms were collected in 47 provinces belonging to 14 departments. Most vouchers are from Amazonia and from the Subandean region. Sites of high diversity and regions poorly collected are pointed out. Finally the potential and limits of the database exploitation are discussed, taking into account the confidence in specimen identification at the specific level, the vagueness in geographic data of several labels, and the sample representativeness.

    Full Text Available Pocos estudios demográficos de larga duración han sido realizados en tortugas dulceacuícolas de Suramérica, pese a la necesidad de este tipo de investigación para esclarecer las variaciones naturales y fortalecer procesos de conservación en este grupo particular. En esta investigación se estudió la variación en la demografía de una población de la tortuga de río chocoana (Rhinoclemmys nasuta, a partir de información registrada en una localidad insular del Pacífico colombiano entre 2005 y 2012. En esta localidad se capturaron manualmente tortugas en cinco riachuelos con un área total de 0,4 ha. Se calculó el tamaño poblacional con el método Jolly-Seber en cuatro periodos (2005–06, 2007, 2011 y 2012, y se comparó la estructura poblacional. Se estimó la probabilidad de supervivencia y la probabilidad de captura para machos, hembras y juveniles utilizando el modelo Cormack-Jolly-Seber, y la tasa de crecimiento poblacional con el modelo POPAN. Se evidenciaron aumentos y disminuciones en el tamaño de la población. Se evidenció un aumento significativo del porcentaje de juveniles que hacen parte de la población durante el periodo de estudio. En todos los periodos las hembras dominaron la estructura de sexos de la población. Las variaciones temporales en el tamaño poblacional pueden deberse a cambios naturales en el hábitat o a efectos denso-dependientes. Sin embargo, también pueden corresponder a fluctuaciones normales en los parámetros poblacionales, por lo tanto monitoreos continuos donde se puedan correlacionar factores ambientales y físicos del hábitat podrían permitirnos elucidar a que se deben estas variaciones.

    Few long-term demographic studies have been conducted in freshwater turtles of South America despite the need for this type of inquiry to investigate natural variation and strengthen conservation efforts for these species. In this study, we examined variation in demography of the Chocoan River turtle (Rhinoclemmys nasuta) based on a population from an island locality in the Colombian pacific region between 2005 and 2012. At this locality we captured turtles by hand in five streams with a total area of 0.4 ha. We calculated population size with the jolly-seber method and compared the population structure of four time periods (2005-06, 2007, 2011 and 2012). we calculated the probability of survival and capture probability for males, females and juveniles using the cormack jolly seber model and we estimated the rate of population growth with the Popan model. We found increases and decreases in population size, and a significant increase in the percentage of juveniles in 2011 and 2012. In all periods, females dominated the sex structure of the population. Temporal variation in population size may be due to natural changes in habitat or density dependent effects. However, it may correspond with normal fluctuations in population parameters, therefore continuous monitoring that can be correlated with environmental and physical factors of the habitat could elucidate the causes of the variation.

    Full Text Available The La Cucaracha site is an important burial ground of archaeological and human remains located in a cavity excavated in the SE flank of Montaña de La Cucaracha volcano, an eruptive vent dated at over 20.000 years. The profusion and diversity of the materials found: pottery shards, stone hand tools and bones, justify the importance of this interment site, although the most significant finding is the presence of human bone fragments embedded in volcanic scoria. The study of this site is focused on identifying the eruptive vent responsible for this event and assessing the incidence of a volcanic eruption on the structure and elemental composition of the recovered osseous materials. For this purpose, radiometric 14C dating has been carried out of the bones affected by the prehistoric eruption in addition to the petrographic and geochemical analysis of the different bone fragments and of the basaltic scoria in which the bone fragments are embedded in relation to the possible surrounding volcanoes. The results obtained point to Montaña Goteras, an eruptive vent close to La Cucaracha volcano, as being responsible for the event, and provide evidence of the preservation of both the mineralogical composition and the crystallographic parameters of the osseous materials. A comparative study reveals significant differences between the bones corresponding to interments and those from cremation ceremonies, the latter showing a marked increase in crystallinity with occasional loss of significative elemental components, variations in contrast to a notable enrichment in trace elements and rare earths undergone by the bone fragments affected by the volcanic eruption. The content in certain oligoelements and SrICa ratios have provided complementary dietary information.El yacimiento de La Cucaracha es un importante enterramiento de restos arqueológicos y humanos situado en una oquedad excavada en el flanco SE del edificio volcánico de la Montaña de La Cucaracha, centro eruptivo con más de 20.000 años. La profusión y diversidad de materiales encontrados: fragmentos cerámicas, industria lítica y restos óseos, justifican la importancia de este yacimiento, pero el hallazgo más significativo es la presencia de fragmentos de huesos humanos englobados en escorias volcánicas. El estudio desarrollado sobre este yacimiento está encaminado a la identificación del centro eruptivo responsable de este acontecimiento y a valorar la incidencia que una erupción volcánica ha tenido sobre la estructura y composición elemental de los materiales óseos. Con esta finalidad, se ha efectuado la datación radiométrica por I4C de los huesos afectados por la erupción prehistórica y el análisis petrográfico-geoquímico de los diversos materiales óseos y escorias basálticas que engloban los restos óseos en relación con los posibles edificios volcánicos circundantes. Los resultados obtenidos señalan a la Montaña Goteras, centro eruptivo próximo al volcán de La Cucaracha, como responsable del suceso, y evidencian la preservación tanto de la composición mineralógica como de los parámetros cristalográficos de los materiales óseos. Su estudio comparativo señala diferencias importantes entre los huesos correspondientes a enterramientos y los procedentes de ceremonias de cremación, los cuales experimentan un señalado incremento de la cristalinidad con algunas pérdidas de componentes elementales significativos, variaciones contrapuestas al importante enriquecimiento en elementos traza y tierras raras que experimentan los fragmentos óseos afectados por la erupción volcánica. Los contenidos en determinados oligoelementos y relaciones de SrICa han permitido obtener información complementaria sobre su dieta alimentaria.

EAECN foi obtido a partir da água da fibra da casca do coco verde e o teste fitoquímico indicou a presença de taninos condensados, flavononas, flavonóis, flavononóis, xantonas e esteróides. EAECN foi administrado aos camundongos Swiss por via oral em dose única diária de 10, 30, 100 e 250 mg Kg-1 por cinco dias consecutivos para os protocolos de toxicidade e inflamação tópica. No ensaio de toxicidade foram observadas as freqüências cardíacas e respiratórias, a presença de diarréia, analgesia e apatia e realizada a contagem total dos leucócitos do sangue periférico, avaliação macroscópica dos órgãos e peso relativo do rim, fígado, timo e baço. O efeito do EAECN sobre a inflamação tópica foi realizado utilizando-se grupos testes com as diferentes concentrações de EAECN e grupos controles positivos que receberam, pela mesma via nas mesmas condições, NaCl 0,9% ou DMSO a 5% ou o antiinflamatório padrão, Dexametasona (6 mg Kg-1. Todos os animais receberam o agente flogístico (25 µL nas partes interna e externa da orelha duas horas após o último tratamento, enquanto os animais do grupo controle negativo não receberam qualquer tratamento. Após 50 minutos da aplicação do xileno, os animais foram sacrificados, e uma porção de cada orelha foi retirada e pesada. A diferença de peso entre as orelhas representa o efeito induzido pelos tratamentos. EAECN não desenvolveu toxicidade, não alterou a contagem total de leucócitos, não alterou o peso e nem o peso relativo dos órgãos dos animais tratados em relação aos controles. EAECN não inibiu a inflamação provocada pelo xileno, apresentando efeito pró-inflamatório dependente da dose. Conclui-se que EAECN nos protocolos utilizados não é tóxico e não possui atividade antiinflamatória tópica.This study aimed to investigate the effect of ethyl acetate extract of Cocos nucifera (EAECN on physiological parameters and xylene-induced topic inflammation. EAECN was obtained from the water of the green coconut husk fiber and the phytochemical test indicated the presence of condensed tannins, flavanones, flavonols, xanthones and steroids. EAECN was orally administered to Swiss mice at a single daily dose of 10, 30, 100 and 250 mg Kg-1 during five consecutive days for toxicity and topic inflammation protocols. Toxicity experiments included the observation of heart and respiratory frequencies, diarrhea, analgesia and apathy, besides total leukocyte count in peripheral blood, macroscopic evaluation of the organs, and relative weight of kidneys, liver, thymus and spleen. The effect of EAECN on topic inflammation was assessed using test groups with different EAECN concentrations and positive control groups which received, by the same route and conditions, NaCl 0.9%, DMSO 5% or reference drug, Dexamethasone (6 mg Kg-1. All the animals received the phlogistic agent (25 µL in the inner and outer parts of the ears two hours after the last treatment, whereas the negative control group animals did not receive any treatment. At 50 minutes after xylene application, the animals were sacrificed and a portion of each of their ears was removed and weighed. The difference between ear weights represents the effect induced by the treatments. EAECN did not develop toxicity, change leukocyte total count, or alter animal weight and organ relative weight in treated animals compared with control groups. EAECN did not inhibit the xylene-induced inflammation, demonstrating dose-dependent pro-inflammatory effect. In conclusion, EAECN used as in these experimental protocols is not toxic and does not have topic anti-inflammatory activity.

    The panorama established in the current scenery signals that the sources of energy renewed they should assume growing paper in the world energy head office, forced by the perspective of reduction of the reservations of fossil fuels and, more and more, for environmental subjects. Among the countless sources you renewed of energy, the biomass is shown as an alternative one quite promising, among the energy of the win and solar. In this context the use of alternative sources of energy, in particular the biomass (residues of cane of sugar and of wood, besides the peel of rice), they appear as an opportunity of private importance to collaborate in the offer of energy of the inter linked system of Brazil, in the form of decentralized generation and close to the consumption points, through equipment and national fuel (example process residues); advantages these that, formed an alliance thoroughly with the environmental benefits known, they do with that the biomass is a strategic option for the country, that only depends on politics adapted for its situation. On the other hand, areas still exist in Brazil, specifically in the North area, that they do not belong to the interlinked system, with generation exclusively based on oil diesel, what corresponds to an important the bottom net in our energy head office. Brazil, besides importer of gross petroleum to refine, it is forced to import oil pure diesel to guarantee the offer of this fuel. In the last ten years the import of oil pure diesel increased ten times data of ANP approximately (www.anp.gov.br). Besides this subject of the import of the diesel and of the emissions current west of its use, such as: oxides of sulfur, material powder and gases of effect stove, among other, the generation in the Isolated Systems with motors diesel (largely old and inefficient) it is based on the subsidies of the Bill Consumption of Fuel (CCC), that pays an additional of US$ 100 for MWh generated in this alternative system. The conventional options for substitution of these motors to diesel depend on investments elevated in transport systems and distribution of the natural gas a substitute of smaller impact to the oil, and still the environmental impacts caused by the gas pipe line construction through the Amazon forest. In this context, the biomass use produced locally (or generated, as residues) in the communities for production of energy appears as a viable and maintainable possibility for this model. Vegetable oils in adapted motors diesel and agricultural residues as fuel in systems of generation of small load come as possible technological alternatives and, now, viable economically, in function of the use of CCC for energy renewed - what became possible for the recent regulation of ANEEL. It is worth to stand out that the different sceneries presented in the regions of the country influence directly in the parameters of use of the biomass as energy. In a general way, the biomass like this maid perfectly in the concept of the maintainable development, because it allows the creation of employments in the area, economic activities, it reduces the relative costs to the distribution and transmission of the generated energy and, when used in a maintainable way, it presents null the emissions of carbon, not attacking, in this way, the environment. However, it is known that the economic viability of a generation project depends, in first place of the characteristics of the own unit, of the tariff of electric energy and of the cost of the fuel for the consumer. Specifically, the viability of each installation is determined in the conceptual project where he/she takes place the cash flow study and of the cost of the energy for modality of fuel. The economic evaluation of a project consists of pondering the factors that involve the taking of decision, with larger success probability in the development of an investment project. After the decision of execution of a project, defined its characteristics, its implementation place, the equipment, the labor and necessary materials, it is necessary to calculate all the involved costs and which will be the necessary investment. The success of any project goes by one it analyzes the most exact possible of the whole necessary investment to the implementation, from investment in lands, constructions, equipment, expenses with personnel in the production and maintenance, to the administration of the project, etc., as well as the determination of its profitability or its 'profit'. After these calculations, it will be necessary to verify investment alternatives that become more advantageous in investment terms and its return exist, that it is necessary to do the comparison of alternatives.

In this study, we examined variation in demography of the Chocoan River turtle (Rhinoclemmys nasuta) based on a population from an island locality in the Colombian pacific region between 2005 and 2012. At this locality we captured turtles by hand in five streams with a total area of 0.4 ha. We calculated population size with the jolly-seber method and compared the population structure of four time periods (2005-06, 2007, 2011 and 2012). we calculated the probability of survival and capture probability for males, females and juveniles using the cormack jolly seber model and we estimated the rate of population growth with the Popan model. We found increases and decreases in population size, and a significant increase in the percentage of juveniles in 2011 and 2012. In all periods, females dominated the sex structure of the population. Temporal variation in population size may be due to natural changes in habitat or density dependent effects. However, it may correspond with normal fluctuations in population parameters, therefore continuous monitoring that can be correlated with environmental and physical factors of the habitat could elucidate the causes of the variation.

    Full Text Available The Brazilian market has been showing a growing concern with nutritional values of oil components of foods. Chemical interesterification is a promising alternative to the current processes of modifying the consistency of oils. Chemical interesterification of deodorized palm oil was studied on a laboratory scale. The best results were obtained with 0.4% MeONa and heating for 20 min at 100 °C. These conditions are based on the largest variation in triacylglycerols as compared to a control. The trisaturated values varied from 6.2 to 9.9%, showing that the consistency of the oil improved for it to be used in margarines, without the formation of trans isomers.

    Full Text Available The germination process of hybrid palm interspecific OxG (E. oleifera x E guineensis. seeds in the company Indupalma ltda has filed a decrease in production, which is reflected in economic losses due to the existence of filamentous fungi that affect seeds. Previous studies have shown the potential controller Trichoderma sp. on these fungi. Commercial and native strains of T. harzianum and T. viride were evaluated against prevalent fungal contaminants of interspecific hybrid palm seeds. They were isolated and identified eleven strains of pathogenic fungi from interspecific hybrid palm seeds that were removed from the different stages of germination. Dual plate tests were conducted at prevalent fungi and the percent inhibition of radial growth (PICO and mycoparasitism were determined. These fungi were inhibited in growth by the antagonistic effect of T. harzianum and T viride. Similarly, T.viride showed a great potential as a biocontrol agent to inhibit over 60% seven out of eleven strains of contaminating fungi.

    The town of Macachin is located over the Valle Argentino aquifer. there, the phreatic aquifer is lodged in a sandy superficial cap and in the slime-sandy sediments. The objective of this work is to depict the pollution of the unconfined aquifer of Macachin, considering the presence of nitrate as determining actor of the quality of the resource. The peri urban area was analysed with the purpose of cover the area of relocalization of the sources of potable water for the town. In the urban area, the domiciliary perforations and in those os supply were considered. Samples in perforations and in drilled wells were collected. Temperature, pH, electrical conductivity and the ions concentration for nitrate and chloride were measured. Statistical basic parameters were calculated for eight wells in exploitation and also for the perforations and drilled wells. It was concluded that the conditions of the underground waters is little satisfactory. All of the domiciliary wells sampled contained a quantity of nitrate that overcomes the maximum levels allowed for the consumption of potable water. In the city's wells of supply a significant increase of the nitrate concentrations was identified since 1998, approximately. The contribution of organic matter to the underground water could be originated in the decomposition of the domiciliary wastes arranged in cesspools. In both areas, the nitrate concentrations in the unsaturated zone are similar and superior to the limit allowed for human consumption. The pollution sources in the rural zone can be permanent corrals of animals. (Author) 10 refs.

    Aiming to study and develop new materials synthesized from sustainable sources, several polymers were prepared using in its monomeric composition, different amounts of NPO (Norbornenyl Palm Oil) monomer. This monomer was developed based on a vegetable oil rather produced in northern Brazil, the Palm Oil. Since this oil have a low content of unsaturation, its use in developing new monomer for ROMP (Ring-Opening Metathesis Polymerization) is not exploited. In this regard, polymeric materials were obtained using the NOP and both the reaction process and the resulting products were analyzed by Nuclear Magnetic Resonance in the time domain (TD-NMR) at low magnetic field.

    This paper compares the performance, for electric power generation, of biodiesel produced by three different insums: soybean oil, palm tree oil and fritter residual oil. For that, it was tested mixtures of diesel oil and biodiesel, at volumetric proportion of 50/50 (B50), in a generator group with four levels of load. The results have shown equivalent performance for all B50 used in the proposed loads, independent of used raw material.
