    Acrocomia aculeata is a plant rich in antioxidant compounds. Studies suggest that this plant has anti-inflammatory, antidiabetic, and diuretic potential. We assessed the antigenotoxic, antimutagenic, immunomodulation, and apoptotic potentials of A. aculeata alone and in combination with an antitumor agent, cyclophosphamide. Swiss male mice (N = 140) were used. The animals were divided into 14 experimental groups as follows: a negative group, a positive group (100 mg/kg cyclophosphamide), groups that only received the oil extracted from the almond (AO) and from the pulp (PO) of A. aculeata at doses of 3, 15, and 30 mg/kg, and the associated treatment groups (oils combined with cyclophosphamide) involving pretreatment, simultaneous, and post-treatment protocols. Data suggest that both oils were chemopreventive at all doses, based on the tested protocols. The highest damage reduction percentages, observed for AO and PO were 88.19 and 90.03%, respectively, for the comet assay and 69.73 and 70.93%, respectively, for the micronucleus assay. Both AO and PO demonstrated immunomodulatory activity. The oils reduced the capacity of cyclophosphamide to trigger apoptosis in the liver, spleen, and kidney cells. These results suggest that A. aculeate AO and PO can be classified as a functional food and also enrich other functional foods and nutraceuticals with chemopreventive features. However, they are not appropriate sources for chemotherapeutic adjuvants, in particular for those used in combination with cyclophosphamide. PMID:27173316

    The growing biodiesel production requires the use of new technologies and alternative feedstocks to maintain the growing demand of this biofuel. The macaw (Acrocomia aculeata) is a palm native to Argentina whose fruits present high oil content. Due to its tolerance to prolonged drought, it is a promising crop for biodiesel and biokerosene production. The aim of this work was to design an agroclimatic zoning model to define the potential growing areas from macaw in Argentina. To define the agroclimatic suitability to produce oil, it was necessary to identify the requirements, limits, and biometeorological tolerance for this palm. In order to define the agroclimatic fitness of this crop in Argentina, the meteorological data corresponding to the period 1981-2010 were employed. The agroclimatic indices were integrated in a Geographic Information System. The maps were superimposed and the overlapping regions delineated the agroclimatic zoning. The agroclimatic zonation classified zones with homogeneous characteristics responding to bioclimatic requirements of this species, resulting in optimal, very suitable, suitable, and nonsuitable areas for macaw cultivation. The authors designed an agroclimatic zoning model based on bibliography. This model can be used in any part of the world, employing the same agroclimatic indices presented in this work.

    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.

    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. PMID:27529077

  7. Estetica de Jose Palma

    Isaac J. Donoso

    2011-06-01

    Full Text Available The day after the death of José Palma (1876—1903, El Renacimiento featured his last verses, an unfinished poem that was entitled “El dolor era el pensamiento fijo de su mente” (Pain was the lasting thought of his mind. This article analyzes the poetic and human career of José Palma within a context, that of the “Philippine Generation of ’98”, especially the revolutionary success which was aborted by an American colonial alienation. Hence, at present, the works of the author of the Philippine national anthem are practically unknown, even if almost one hundred million Filipinos sing the national anthem every day in translated versions. Consequently, the poetics and historical context that generated the Himno Nacional Filipino are compromised. In order to comprehend the cultural scenario during which the Philippine Revolution arose, this paper will analyze the poetic features that distinguished José Palma’s works, and the gloomy conundrum exposed in his literary testament.

The characteristics evaluated were: percentage of emergence, emergence first count, emergence speed index, height and dry weight of seedlings. In the treatments that involved immersion in water in 60ºC, 70ºC, 80ºC and 90ºC, a low percentage of emergence was obtained. The P. aculeate seeds tegumentary dormancy is overcome with maximum efficiency by the mechanical scarification with sandpaper, suggesting that, in natural environment the movement of contraction and expansion of the soil results in a mechanical scarification of the tegument of the seeds, thus, allowing a high percentage of germination with distribution as time passes.

    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.

    Souza, Lucéia F; Gasparetto, Bruno F; Lopes, Rodrigo R; Barros, Ingrid B I

    2016-04-01

    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).

    2014-12-01

    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.

  5. PALMA, an improved algorithm for DOSY signal processing

    Cherni, Afef; Delsuc, Marc-André

    2016-01-01

    NMR is a tool of choice for the measure of diffusion coefficients of species in solution. The DOSY experiment, a 2D implementation of this measure, has proven to be particularly useful for the study of complex mixtures, molecular interactions, polymers, etc. However, DOSY data analysis requires to resort to inverse Laplace transform, in particular for polydisperse samples. This is a known difficult numerical task, for which we present here a novel approach. A new algorithm based on a splitting scheme and on the use of proximity operators is introduced. Used in conjunction with a Maximum Entropy and $\\ell_1$ hybrid regularisation, this algorithm converges rapidly and produces results robust against experimental noise. This method has been called PALMA. It is able to reproduce faithfully monodisperse as well as polydisperse systems, and numerous simulated and experimental examples are presented. It has been implemented on the server http://palma. labo.igbmc.fr where users can have their datasets processed autom...

    Ivone Garros-Rosa

    2006-06-01

    Full Text Available Successive aqueous (10 ºC, 25 ºC and 80 ºC and alkaline (1M NaOH; 25 ºC extractions of milled Parkinsonia aculeata endosperms gave rise to four galactomannan fractions. These extractions furnished viscous galactomannans with Man:Gal ratios ranging from 3.1:1; 3.7:1; 4.9:1 and 6.1:1 (P1, P2, P3 and P4, respectively. Fraction P1 was used for structural studies by using methylation analysis, periodate oxidation and 13C-NMR. It showed a linear backbone of beta(1->4 linked D-mannose units, to which single alpha(1->6-linked D-galactose are attached. This galactomannan has Mw 775700 g/mol and intrinsic viscosity of 558 mL/g. The four fractions and the crude endosperm were treated with epichlorydrin and used as matrix for affinity chromatography. All columns tested showed ability to bind lectin samples. The efficiency is related to the degree and pattern of substitution of galactosyl units on the D-mannan backbone.

    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.

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

    Stephanie Domaschke

    2012-03-01

    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.

    S Narendhran; Rajeshwari Sivaraj

    2016-02-01

    In this study, Zinc oxide (ZnO) nanoparticles were synthesized using aqueous extract of Lantana aculeata Linn. leaf and assessed their effects on antifungal activity against the plant fungal pathogens. Synthesized nanoparticles were confirmed by ultraviolet–visible spectroscopy, Fourier transform infrared spectrometer, energy-dispersive X-ray spectrometer, X-ray diffractometer, Field-emission scanning electron microscopy, high-resolution transmission electron microscopy. The antifungal activity of ZnO nanoparticles were determined using the well diffusion method. All the characterization analyses revealed that nanoparticles were highly stable and crystalline in nature. L. aculeata-mediated ZnO nanoparticles were spherical in shape with an average particle size of 12 ± 3 nm. Antifungal studies concluded that the maximum zone of inhibition was observed in Aspergillus flavus (21 ± 1.0 mm) and Fusarium oxysporum (19 ± 1.0 mm) at 100 g ml-1 concentration. These results clearly indicated the benefits of using ZnO nanoparticles synthesized using biological methods and shown to have antifungal activities and also that it can be effectively used as antifungal agent in environmental aspect of agricultural development.

  13. The 1677 eruption of La Palma, Canary Islands

    Rodríguez Badiola, E.

    1996-08-01

    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

  19. Impact of cytomixis on meiosis, pollen viability and pollen size in wild populations of Himalayan poppy (Meconopsis aculeata Royle)

    V K Singhal; Puneet Kumar

    2008-09-01

    We report the occurrence of cytomixis in wild populations of Himalayan poppy (Meconopsis aculeata Royle), which is considered to be an important and threatened medicinal plant growing in the high hills of the Himalayas. The impact of cytomixis on meiotic behaviour, reduced pollen viability and heterogeneous-sized pollen grains was also studied. Cytological studies in the seven wild populations from the high hills of Himachal Pradesh revealed that all the Himalayan populations exist uniformly at the tetraploid level (2n=56) on x=14. The phenomenon of chromatin transfer among the proximate pollen mother cells (PMCs) in six populations caused various meiotic abnormalities. Chromatin transfer also resulted in the formation of coenocytes, aneuploid, polyploid and anucleated PMCs. Among individuals that showed chromatin transfer, chromosome stickiness and interbivalent connections were frequently observed in some PMCs. The phenomenon of cytomixis in the species seems to be directly under genetic control; it affects the meiotic course considerably and results in reduced pollen viability.

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

    Vives-Miró, Sònia

    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.

  1. SAGE CALCULATIONS OF THE TSUNAMI THREAT FROM LA PALMA

    Galen Gisler

    2006-01-01

    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.

  2. Crystal structure of pyruvate decarboxylase from Zymobacter palmae.

    Buddrus, Lisa; Andrews, Emma S V; Leak, David J; Danson, Michael J; Arcus, Vickery L; Crennell, Susan J

    2016-09-01

    Pyruvate decarboxylase (PDC; EC 4.1.1.1) is a thiamine pyrophosphate- and Mg(2+) ion-dependent enzyme that catalyses the non-oxidative decarboxylation of pyruvate to acetaldehyde and carbon dioxide. It is rare in bacteria, but is a key enzyme in homofermentative metabolism, where ethanol is the major product. Here, the previously unreported crystal structure of the bacterial pyruvate decarboxylase from Zymobacter palmae is presented. The crystals were shown to diffract to 2.15 Å resolution. They belonged to space group P21, with unit-cell parameters a = 204.56, b = 177.39, c = 244.55 Å and Rr.i.m. = 0.175 (0.714 in the highest resolution bin). The structure was solved by molecular replacement using PDB entry 2vbi as a model and the final R values were Rwork = 0.186 (0.271 in the highest resolution bin) and Rfree = 0.220 (0.300 in the highest resolution bin). Each of the six tetramers is a dimer of dimers, with each monomer sharing its thiamine pyrophosphate across the dimer interface, and some contain ethylene glycol mimicking the substrate pyruvate in the active site. Comparison with other bacterial PDCs shows a correlation of higher thermostability with greater tetramer interface area and number of interactions. PMID:27599861

  5. Metasomatism in the oceanic lithosphere beneath La Palma, Canary Islands

    Janisch, Astrid; Ntaflos, Theodoros

    2016-04-01

    La Palma is the most active island within the Canary archipelago with historical eruption along the Cumbre Vieja Rift. Mantle peridotite xenoliths brought to the surface during the eruption 1677/78 at the site of San Antonio Volcano, close to Fuencaliente in the south of the island, gives us an excellent opportunity to study an old oceanic lithosphere. The collection of xenoliths comprises sp-harzburgites, sp-lherzolites, sp-dunites and pyroxenites but only the first three were used for this work. Metasomatic processes are evident in all samples. A common feature is a variable channelling of melt flow through the mantle xenoliths displayed in variations from pervasively metasomatized, through veined to dyke intruded peridotites. Orthopyroxene breakdown into olivine, clinopyroxene and glass is evidence for anhydrous melt percolation. Furthermore, fine-grained veins in various thicknesses consisting of olivine, pyroxene as well as amphibole with apatite and phlogopite reveal additional anhydrous and hydrous metasomatic processes, respectively. Peridotites mainly influenced by anhydrous metasomatism exhibit locally phlogopite and/or amphibole around spinel or in glass-veinlets. Pentlandite has been found in all veined samples. Amphiboles are mostly pargasites but kaersutites are also present in the amphibole-bearing veins. Two different types of amphibole veins have been recognized. The first type is an amphibole-apatite-glass-bearing amphibolite, forming a cross-cutting vein that propagates through the xenolith. The amphiboles in this vein are coarse-grained while the disseminated amphiboles are fine-grained. Clinopyroxene always occurs in association with amphibole and in textural equilibrium suggesting that both minerals have grown together. The glass is of tephritic/basanitic to trachy-basaltic composition. The second amphibole-vein contains phlogopite and traces of apatite. Textural evidence (cross-cutting olivine grains and the absence of hydrous minerals in the

  8. EFFECT OF HARVESTING AGE ON THE CHEMICAL AND MORPHOLOGICAL PROPERTIES OF DHAINCHA (SESBANIA ACULEATA AND ITS PULPABILITY AND BLEACHABILITY

    M. Sarwar Jahan

    2009-05-01

    Full Text Available Dhaincha (Sesbania aculeata is one of the annual plants in Bangladesh that has potential as a fiber source. It is a crop generally cultivated for its nutritive value to soil. This paper describes the effect of harvesting age of dhaincha on chemical, morphological, pulp, and papermaking properties and its bleachability. Dhaincha is a short length fiber that can be used as a substitute to hardwood. Fiber length was found to increase slightly with increasing age of the plant. The alpha-cellulose content in dhaincha increased and pentosan decreased with increasing age. Dhaincha pulp was prepared from 2, 3, 4, 5, and 6 month old plants under identical cooking conditions. Pulp yield (43-45 % and kappa number (26-30 did not follow direct correlation with plant age. But physical properties of unbleached pulp increased linearly with the increase of age. Bleachability of dhaincha pulp was quite poor. The bleachability of pulp was improved when the age of dhaincha was increased.

  9. Growth, nodulation and N2 fixation in sesbania aculeata grown in soil supplied with different rates of phosphogypsum using 15N isotopic dilution technique

    The impact of five rates of phosphogypsum PG (0, 5, 10, 20 and 40 ton/ha) on growth, nodulation and N2 fixation by dhaincha (Sesbania aculeata Pers.) was evaluated in a pot experiment. The same effect on the growth of sorghum (Sorghum bicolor L), which was utilized as a reference crop for measuring N2 fixation by the legume crop using the 15N isotope dilution method, was also investigated. Dry matter of sorghum doubled when soil supplied with the lowest rate of PG (5 t/ha). In sesbania, the highest rate of PG (40 t/ha) was found to have a significant effect on dry matter yield. PG had a beneficial effect on P accumulation on both plant species, particularly in sesbania's nodules. The beneficial effect of PG in S. aculeata was more pronounced on nodulation and N2 fixation than on growth of the host plant. The highest value of %N2-fixation (67%) obtained following the addition of 10 t of PG/ha; whereas, it was only 35% in the control treatment (PG0). Moreover, the amount of N2 fixed was doubled when soil supplied with PG, particularly in the PG10 treatment. Concentrations of fluorine in shoots of both plant species were less than 10 mg/kg which remained less than the allowable level. Soil supply with PG, particularly 10 t/ha, can be considered as an effective way for improving nodulation, N2 fixation and P availability in Sesbania aculeata with minimal soil N uptake. (author)

  16. The problem of employment in Palmas-PR: a proposal of breaking the vicious cycle

    Alexandre Luiz Schlemper

    2015-11-01

    Full Text Available The study presents a brief reflection on the development status in Palmas-Paraná State (Brazil, from a diagnosis of employment dynamics. For such aspects concerning the distribution of employment by economic activities, their turnover and internal migration are posed. The methodology used secondary data on employment with CAGED as a source, in addition to interview with the workers agency in Palmas. The diagnosis concludes that there is a problem of high turnover of jobs, mainly in the timber industry of plywood sheets, in which labor migrates seasonally to the temporary activities of apple and potato harvest, later returning to industry, thus forming a vicious cycle. This cycle is evaluated by Gunnar Myrdal’s theory of circular and cumulative causation, according to which, also are presented suggestions for breaching and converting it into a virtuous cycle. The proposals are based on the opportunity to build a participative planning led by the movement of the organized civil society called Palmas Developed and the performance of Parana Federal Institute in its teaching, research and extension, promoting new economic activities driving local development.

  18. Solidarity finance through community development banks as a strategy for reshaping local economies: lessons from Banco Palmas

    Genauto Carvalho de França Filho

    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.

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

    Bru, Guadalupe; Gonzalez, Pablo J.; Fernandez-Merodo, Jose A.; Fernandez, Jose

    2016-04-01

    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

  5. Producing a “Successful City”: Neoliberal Urbanism and Gentrification in the Tourist City—The Case of Palma (Majorca

    Sònia Vives Miró

    2011-01-01

    Full Text Available Since the 1990s, the intensification of capital accumulation, especially in its financial dimension, has been one of the keystones for the triumph of neoliberalism. Spanish neoliberal policies have focused on the flexibilization of the real estate sector, leading to the specialization in the secondary circuit of accumulation. This has generated a third real estate boom which has been accompanied with an outstanding housing bubble. The Balearic Islands are a paradigmatic case within these logics, tourist specialization being the main trigger of the process. In Palma, the region's capital, neoliberal urban planning policies have been implemented in order to convert it into a “successful city” within the global urban network competition. These policies have led to Palma's uneven geographical development through processes like gentrification, as is the case of the Gerreria, a neighborhood of Palma's city center.

  7. Growth and N-uptake of sorghum grown on saline soil as affected by green manuring with sesbania aculeata plant residues using the indirect 15N isotopic dilution method

    A field experiment was conducted to determine the effects of manuring with three types of plant residues (R, roots; L, shoots and L+R shoots plus roots) of dhaincha (Sesbania aculeata Pers.) on the growth of sorghum (Sorghum bicolor L.) grown on a saline soil using the indirect 15N isotopic dilution technique. The use of Sesbania aculeata residues, particularly the shoots, as green manure, can provide a substantial portion of total N in sorghum, enhanced soil N uptake, and increased water use efficiency. Moreover, the use of sesbania green manure in saline soils, as a bio-reclaiming material, can be a promising approach for enhancing plant growth on a sustainable basis. (author)

  9. Methodology for generation of hydrogeologic maps: rio da Palma watershed case study, DF, Brazil

    Hélio Nóbile Diniz

    2007-08-01

    Full Text Available This paper had the objective of developing a methodology to support the management of water resources, based on hydro geological cartography, tested for the hydro geologic conditions of a watershed located at Central Brazil. Results show two major products: a hydro geologic, and a potential infiltration and recharge maps of the high course of the Rio da Palma watershed. This paper is presented in six parts. The first one discusses the map’s elements, essential thematic maps and appropriate scales. The second part proposes the graphic criteria for the integrated representation of the major parameters of overlaying aquifers. The third part demonstrates the importance of the data basis for the hydro geologic cartography, i.e., the contribution of each theme such as soil, geology, slope, climate and land use, when appropriately integrated. The fourth part discusses the selection and the integration of the main information layers for the Rio da Palma watershed using a Geographic Information System (GIS. On the fifth part, the result of the integration of the porous domain with the fractured domain aquifer information layers is shown and, finally, the potential infiltration and recharge map of the studied area, elaborated from the integration of overlapping of the data basis information layers is presented and discussed. In general, in the studied area, regions with high infiltration potential prevail where human interference is still moderate. Large portions of low infiltration potential are either associated with high slopes, with shallow soils (Cambissolos or else with urban constructions.

  12. Effect of different saline water levels on growth, nodulation, and N2-fixation by sesbania aculeata pers, and on growth of helianthus annuus l. using 15N tracer technique

    Effect of different levels of salinity of the irrigation water having electrical conductivities (ECw) in a range 1.1 to 33 ds/m on nodulation dry matter production and N2 fixation by dhaincha (Sesbania aculeata Pers) was evaluated in a pot experiment. Such an effect was also studied on sunflower (Helianthus annuus L) as a reference crop for measuring N2-fixation by the legume crop using a 15N isotope dilution method. Irrigation with water having ECw of more than 4.03 ds/m reduced plant growth and the reduction was more pronounced in S. Aculeata than in H. Annuus. %N2 fixation was significantly enhanced under a moderate salinity level in irrigated water (ECw of 4.3 ds/m), whereas, small effects were obtained at higher saline water levels (up to 12.3 ds/m). The results indicated that Sesbania aculeata and Helianthus annuus grown in saline soils can be irrigated either with water having up to 8.03 ds/m for the former and 12.3 ds/m for the latter species, or with gradually increased levels of salinity for both of them.

  14. Palma: The oscillating core of a suspended periphery. An imagologic approach to an island city and its discourse of pleasure

    Eduard Moyà

    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.

  15. pt5m - a 0.5m robotic telescope on La Palma

    Hardy, L K; Dhillon, V S; Littlefair, S P; Wilson, R W

    2015-01-01

    pt5m is a 0.5m robotic telescope located on the roof of the 4.2m William Herschel Telescope (WHT) building, at the Roque de los Muchachos Observatory, La Palma. Using a 5-position filter wheel and CCD detector, and bespoke control software, pt5m provides a high quality robotic observing facility. The telescope first began robotic observing in 2012, and is now contributing to transient follow-up and time-resolved astronomical studies. In this paper we present the scientific motivation behind pt5m, as well as the specifications and unique features of the facility. We also present an example of the science we have performed with pt5m, where we measure the radius of the transiting exoplanet WASP-33b. We find a planetary radius of 1.603 +/- 0.014 R(J).

    Genestar, Catalina; Pons, Carmen; Cerro, José Carlos; Cerdà, Víctor

    2014-01-01

    The effects of atmospheric pollutants and climatic conditions were studied in a decayed column in the Seminary of Sant Pere. This nineteenth-century building is situated in the historic centre of Palma (Mallorca, Spain), less than 0.5 km from the sea. Samples were collected from the internal and external part of the crusts formed in the four sides of the column. The samples were analysed by means of thermal analysis, X-ray diffractometry, scanning electron microscopy, Fourier transform infrared spectroscopy and ion chromatography. Results show significant differences in the four sides of the column. A high degree of carbonate stone sulfation is observed in all of the samples analysed. A synergistic effect between atmospheric factors and micropollutants on the deterioration of stone is observed. A high uptake of atmospheric particulate matter is found in the external part of the black crusts. PMID:24705948

  19. Grazing effects on species composition in different vegetation types (La Palma, Canary Islands)

    Arévalo, J. R.; de Nascimento, L.; Fernández-Lugo, S.; Mata, J.; Bermejo, L.

    2011-05-01

    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.

  6. Inhibition of plasma butyrylcholinesterase activity in the lizard Gallotia galloti palmae by pesticides: a field study

    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

    A field experiment was conducted under saline conditions (soil ECe 15, water ECw 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 N2-fixation using 15N 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 N2 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 N2 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.

  11. Measurement of N2 fixation in Sesbania aculeata and Sorghum bicolor L. grown in intercropping system using 15N isotopic dilution technique

    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 ECe 0.16, water ECw1dS/m) to evaluate dry matter production, total N yield, soil N uptake and N2-fixation using 15N 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 N2 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 N2 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, N2-fixation and soil N uptake balance of the component crops.

    2016-01-01

    Full Text Available La escasez de alimento para el ganado vacuno en la época de pocas lluvias ocasiona la pérdida de peso y producción en vacas lac-tantes. Este estudio pretende demostrar la viabilidad de reemplazar la pastura por lodo de palma durante los períodos de escasez manteniendo los niveles de producción de leche y carne de las vacas lactantes. Para esto se contó con cinco tratamientos donde se adicionó 2, 5, 8 y 11 kg de lodo de palma más un tratamiento sin adición (control por 60 días. Durante este lapso de tiempo se registró el peso de la leche y del animal cada tres días. Para la variable peso del animal se obtuvo que el mejor y peor tratamiento corresponde al control y 11 kg de lodo de palma respectivamente; para la variable producción de leche el mejor tratamiento corresponde a 11 kg de lodo de palma y el peor tratamiento es el control. Se concluye que el tratamiento que presenta una buena relación de peso del animal y producción de leche corresponde a las vacas alimentadas con 5 kg de lodo de palma ya que ambas variables se ubican como segundo mejor tratamiento con una variación de 11% y 9,50% respectivamente.

  13. The husk fiber of Cocos nucifera L. (Palmae is a source of anti-neoplastic activity

    P.R. Koschek

    2007-10-01

    Full Text Available 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 104/well were incubated with 0, 5, 50 or 500 µg/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 µg/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.

  14. Under the volcano: phylogeography and evolution of the cave-dwelling Palmorchestia hypogaea (Amphipoda, Crustacea at La Palma (Canary Islands

    Oromí Pedro

    2008-01-01

    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.

  6. Magma transport beneath La Palma: inferences based on fluid inclusion and mineral-melt thermobarometry

    Galipp, K.; Kluegel, A.; Hansteen, T.

    2003-04-01

    La Palma (Canary Islands) represents a hotspot island with an active rift zone, inferred to have formed during the last 800 ka following southward growth of the former radial-symmetrical stratovolcano Taburiente /1/. The aim of our study is to model the magmatic evolution of the rift system from its early stage (Cumbre Nueva) through the short Bejenado volcano phase which followed the Cumbre Nueva collapse (560-549 ka) to the presently active rift zone (Cumbre Vieja). Clinopyroxene-melt thermobarometry and microthermometry of fluid inclusions were applied to constrain magma pathways and major levels of magma stagnation. CO2- dominated fluid inclusions in olivine and clinopyroxene in Taburiente picrites show density distributions with maxima at 0.7-0.85 g/cm-3. These values correspond to equilibrium pressures of 400-600 MPa, in accordance with other Taburiente data /2/. Inclusion data of a Cumbre Nueva ankaramite give pressure estimates of 200-300 MPa. In comparison, fluid inclusions in Recent Cumbre Vieja rocks yield a pronounced pressure estimate at 200-400 MPa, which overlaps with the Cumbre Nueva data but is shallower than that for Taburiente. Clinopyroxene-melt barometry of phenocryst rims and glassy groundmass yield pressure maxima between 600 and 900 MPa for Taburiente, Bejenado and Cumbre Nueva. This pressure range partly overlaps with that for Cumbre Vieja (maximum between 500 and 800 MPa) but has a tendency to higher pressures. The combined data indicate that two separate magma stagnation levels are distinct for each rift phase: (1) a main fractionation level within the upper mantle which is common to all phases, and (2) intermittent stagnation close to the Moho for the Taburiente volcano and above the Moho for both the Cumbre Nueva and Cumbre Vieja. Observing that the present rift system and the early stages of the rift show different levels of fractionation and magma stagnation and also show compositional differences between the lavas, we suggest that

    2008-03-01

    Full Text Available The characteristics of the seeds from Chilean palm and the detailed composition of its fat are studied starting from 4 lots of seeds from the two regions being the major producers of Chilean palm seeds. From the proximate composition of the seeds a high content of fats is deduced with a mean value of 67.3%. The contents of proteins, carbohydrates and fibre were in the range of 7-11%. A detailed analysis of the fat indicates a high content of saturated fatty acids being capric, caprilic, lauric and miristic acids the major fatty acids. For this reason the presence of a high percentage of medium-chain triglycerides are detected in the triglyceride analysis. As for tocopherols, the fat contains low amounts of α-, γ- y δ-tocopherol with a total average of 84 mg/kg. Concerning phytosterols, the total content was around 1000 mg/kg being β-sitosterol and Δ7-estigmastenol the two major sterolsSe analizan las características generales del coquito de palma chilena y se estudia con detalle la composición de su aceite. Con este objetivo, se analizan 4 lotes de coquitos procedentes de las dos regiones de Chile donde existe mayor producción. La composición proximal del coquito indica un contenido muy mayoritario de grasa, con un promedio de 67,3% mientras los contenidos de proteínas, hidratos de carbono y fibra se encuentran entre el 7 y el 11%. Un análisis detallado de la grasa muestra un contenido elevado de ácidos grasos saturados (alrededor del 85% siendo los ácidos cáprico, caprílico, láurico y mirístico los que se encuentran en mayor concentración, lo que origina un elevado porcentaje de triglicéridos de cadena media. Respecto a los tocoferoles, el aceite contiene cantidades limitadas de α-, γ- y δ-tocoferol con un valor promedio total de 84 mg/kg, no detectándose la presencia de tocotrienoles. Respecto a los fitoesteroles, el contenido total es del orden de 1000 mg/kg siendo los esteroles mayoritarios el

    Camilo Rey Sabogal

    2013-12-01

    Full Text Available En este artículo se examina la existencia de una posible correlación entre cultivos de palma de aceite y el desplazamiento forzado en Colombia. Este análisis se plantea con la perspectiva de la econometría espacial porque se identificó autocorrelación y clústeres en las variables entre las unidades geográficas municipales. Por ello se emplea la estrategia regresión geográficamente ponderada, la cual estima ecuaciones municipales que tienen en cuenta el comportamiento de las variables en los municipios vecinos. Como resultado se encontró un patrón de relación directa entre cultivos de palma y desplazamiento en unidades geográficas en el cual los cultivos se impulsaron en la última década. Se debe aclarar que este artículo no evalúa aún la relación de causalidad entre las variables, aspecto que requiere nuevos datos y ajustes metodológicos.

Utilizando el método de los recorridos urbanos, durante un año se registraron los datos de temperatura y humedad de 42 puntos de la ciudad, que incluyen áreas formales y funcionales diferentes. Los resultados confirman la existencia de una isla de calor nocturna de carácter bifocal y de intensidad moderada, aunque puede llegar a alcanzar valores de 5.3º C. 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.

  13. 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.

    Full Text Available RESUMENLa palma Sabal mauritiiformis es un recurso importante en el Caribe colombiano debido al uso de sus hojas para techar. Para evaluar el estado de sus poblaciones en Piojó (Atlántico, uno de los municipios más productores de hojas, se estudió la densidad y la estructura poblacional de la palma. Se establecieron 16 parcelas de 0,1 ha, en los tres sistemas de uso de suelo más comunes en la zona: ganadería (6, cultivos (5 y rastrojo (5. Se encontró que la palma amarga constituye un recurso silvestre, muy resistente y capaz de adaptarse a ambientes perturbados pues está incorporada en sistemas productivos de cultivos, rastrojos y ganadería, donde las prácticas de manejo influyen en la densidad y estructura de sus poblaciones. La palma es muy resistente y capaz de adaptarse a ambientes perturbados. El área estudiada incluyó 5349 individuos distribuidos en cuatro categorías de tamaño. Los rastrojos (3620 ± 2808 individuos/hectárea y los cultivos (5612 ± 3361 ind/ha presentaron más individuos y mejores estructuras poblacionales que las áreas de ganadería (1488 ± 827 ind/ha, en las cuales se encontraron poblaciones más deterioradas por efecto del pisoteo y el forrajeo. La prevalencia de individuos en algunas clases de tamaño refleja las condiciones de manejo actual e histórico; actividades como el pastoreo o las quemas, sin una apropiada planificación, pueden comprometer el desarrollo de las poblaciones de la palma y la futura disponibilidad del recurso.ABSTRACTThe palm Sabal mauritiiformis is an important resource in the Colombian Caribbean, as its leaves are used for thatching.

    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.

  19. Saharan mineral dust outbreaks observed over the North Atlantic island of La Palma in summertime between 1984 and 2012

    Laken, Benjamin A; Pallé, Enric; Shahbaz, Tariq

    2013-01-01

    We estimate the frequency of Saharan mineral dust outbreak events observed over the North Atlantic island of La Palma based on in situ nightly atmospheric extinction measurements recorded almost continuously since 1984 by the Carlsberg Meridian Telescope at the Roque de los Muchachos observatory. The outbreak frequency shows a well-defined seasonal peak in the months of July to September, during which time the occurrence of Saharan dust events (SDEs) is approximately 28\\pm6%. We find considerable year-to-year variability in the summertime SDEs frequency, observing a steady reduction between 1984 and 1997, followed by a period of relative mean stability from 1999 to 2012. We investigated changes in the atmospheric extinction of the SDEs as an indicator of strength of the episodes and found that this parameter approximately follows the SDE frequency, however, instrumental limitations prevented us from deriving precise conclusions regarding their long-term changes. A lagged correlation analysis between SDE prope...

  9. 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

    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 15N-labelled inorganic N-fertilizer (indirect method) or 15N-labelled sesbania leaves (direct method). For the indirect method, both soils manured with each type of sesbania residue, received four split applications of 15N-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 saline

    2005-01-01

    Full Text Available En este artículo se presentan los resultados de las prestaciones mecánicas y ambientales de un motor diesel de automoción de 2.5 litros de cilindrada, turboalimentado, montado en banco de ensayos, que utiliza diesel corriente y biodiesel de aceite de palma mezclado al 5, 10 y 20% en volumen. Los ensayos se realizaron a igualdad de energía en el cigüeñal para cada combustible, en cinco grados de carga estacionarios, representativos de las condiciones de operación del vehículo en ciudad. Se obtuvo un incremento en el consumo específico de combustible respecto al diesel corriente en torno a 0.5, 1 y 1.7% al usar B5, B10 y B20 respectivamente. El rendimiento efectivo no sufrió cambios estadísticamente significativos, con lo cual se comprobó que la relación energía suministrada a energía obtenida en el cigüeñal se mantuvo constante independientemente de la mezcla de biodiesel. Las emisiones específicas de THC (gTHC/kWh disminuyeron aproximadamente en la misma proporción que el contenido de biodiesel en la mezcla (5, 10 y 20%, para B5, B10 y B20 respectivamente. Las de CO y la opacidad de humos (% disminuyeron en la misma proporción, correspondiente con la mitad del contenido de biodiesel en la mezcla (2.5, 5 y 10%, para B5, B10 y B20 respectivamente. Las emisiones específicas de NOx incrementaron ligeramente, y alcanzaron un máximo para la mezcla B20 en torno al 3% respecto al diesel corriente. Se presentan los índices de emisión en términos de masa de contaminante por unidad de masa de combustible quemado. Los resultados permiten concluir que el uso del biodiesel de aceite de palma mezclado en concentraciones inferiores al 20% con diesel convencional tiene ventajas ambientales significativas. Desde el punto de vista mecánico, el consumo adicional de combustible se ve apenas ligeramente incrementado sin afectar el rendimiento efectivo del motor.

    Pedro C. Quintana Andrés

    2013-10-01

    Full Text Available La propiedad y la explotación de la tierra en Canarias durante el Antiguo Régimen son factores fundamentales para comprender la evolución histórica de su formación social. Las relaciones de producción, de acumulación de la propiedad agraria y la distribución de las rentas son algunos de los parámetros sobre los que descansa el sistema socioeconómico regional. Los contratos agrarios registrados en La Palma –arrendamientos, medianerías- se muestran como valiosas referencias para conocer los procesos de deforestación, de avance de la agricultura, de las transformaciones en la producción agraria, en la concentración de la propiedad o en la movilidad de la mano de obra campesina. Los acuerdos contractuales para la explotación de la tierra reflejan, en gran medida, la progresión de los procesos de profundización en el mundo agrario del sistema de complementariedad económica regional, de los efectos de las fluctuaciones del mercado exterior, sobre todo en referencia a la producción de vinos, o las tendencias del consumo en Canarias.Property and the use of land in the Canary Islands under the previous regime are fundamental factors for understanding the historical evolution of their social formation. The relations of the factors of production, the accumulation of agricultural property and the distribution of wealth are some of the parameters on which the regional socio-economic system rests. The agrarian contracts on record in La Palma - leases, tenancy farming- are valuable references for discovering the processes of deforestation, the advance of agriculture, the transformation in ownership of agricultural lands, the concentration of ownership and the mobility of rural labour. The contractual agreements for working the land show, to a large extent, the progression of the processes of development of the agrarian world of the regional system of complementary economic advantages, the effects of the fluctuations in the overseas market

  13. [Composition, abundance and infestation rate of ant species in a children's hospital in the city of Palmas, Tocantins, Brazil].

    Bragança, Marcos A L; Lima, Jefferson D

    2010-01-01

    This first survey of the ant fauna in a children's hospital in the city of Palmas, state of Tocantins, compares species composition, abundance and infestation rate of ants between rainy and dry seasons, day and night periods, and among 15 hospital sectors. Forty-eight collections, being 12 diurnal and 12 nocturnal in each season using five attractive baits distributed per sector, maintained for 3h per sampling. A total of 34,309 ants were collected, distributed in 12 species: Acromyrmex sp., Brachymyrmex sp., Camponotus spp. (four morphospecies), Dorymyrmex sp., Tetramorium sp., Solenopsis globularia (Creighton), Solenopsis saevissima Smith, Tapinoma melanocephalum (Fabricius) and Paratrechina longicornis (Latreille). The hospital presented an average building infestation rate (40.3%), when compared with hospitals from other Brazilian regions. In general, there was no difference in the species composition between seasons and the period of the day, although abundance of ants was higher at night. The dry season and the nocturnal period showed the highest infestation rate, mainly by T.melanocephalum and S.globularia. Gynecologic ward, lactation unit, preconception and pediatric ward access ramp showed higher infestation rate, although these varied between seasons. The significant infestation levels by the three species above, especially in sectors with restricted access such as lactation unit, laboratory, Intensive Care Unit e surgery center, indicate potential risks for contamination of patients by multi resistant pathogens possibly present in ants' bodies, as verified in others studies.

  14. Three Neoclassicisms. Exploring the Possibilities of a Comparative Average Shot Length Through Clint Eastwood, Brian De Palma and Woody Allen

    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.

    Full Text Available Diabetes mellitus, a non-communicable disease that can affect men and women, can be classified as type I or type II. This disease is in the 4th position in numbers of deaths in Brazil, and therefore, involves attention, both from the government, as the patients and family. The aims of this study is describe the lifestyle in relation to diet, foot care and proper medication, and the point of view of patients with diabetes mellitus type II, on the importance of the practice of physical exercise, coordinated and programmed. We performed a study using Questionnaire of Self-Care Activities with Diabetes (QAD and a second questionnaire with questions related to the importance of exercise for patients with diabetes mellitus type II. Questionnaires were applied in 20 patients with the disease (08 men and 12 women, living in the city of Palmas, Tocantins, Brazil. Result: We noticed that even with the recommendations of healthcare professionals, most patients with diabetes mellitus type 2 has not adapted verification of blood glucose, proper nutrition and foot care. Moreover, despite the interviewees know the importance of performing regular physical activity, we noticed that these do not know how much of weekly days in which they must get physical exercise in order to control the disease. Most interviewees adopt just walk as the physical activity, and we have not verified from the answers of patients, if they know what the most beneficial exercises to control this disease.

    2004-10-01

    Full Text Available The relationship between whole-system metabolism estimates based on planktonic and benthic incubations (bare sediments and seagrass, Posidonia oceanica meadows, and CO2 fluxes across the air-sea interface were examined in the Bay of Palma (Mallorca, Spain during two cruises in March and June 2002. Moreover, planktonic and benthic incubations were performed at monthly intervals from March 2001 to October 2002 in a seagrass vegetated area of the bay. From the annual study, results showed a contrast between the planktonic compartment, which was heterotrophic during most of the year, except for occasional bloom episodes, and the benthic compartment, which was slightly autotrophic. Whereas the seagrass community was autotrophic, the excess organic carbon production therein could only balance the excess respiration of the planktonic compartment in shallow waters (2 fields and fluxes across the bay observed during the two extensive cruises in 2002. Finally, dissolved inorganic carbon and oxygen budgets provided NEP estimates in fair agreement with those derived from direct metabolic estimates based on incubated samples over the Posidonia oceanica meadow.

  19. Geología y vulcanología de La Palma y El Hierro, Canarias Occidentales

    Pérez Torrado, F. J.

    2001-12-01

    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

    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.

    Full Text Available This study evaluated occurrences of Leishmania infantum in dogs in the municipality of Palmas, Tocantins, comparing diagnostic data obtained using the polymerase chain reaction (PCR and parasitological diagnosis. Blood samples and lymph node aspirates were collected from 63 dogs of males and females and various ages and races, with or without owners, between August 2009 and June 2010. Slides containing smears of lymph node aspirates were stained with Giemsa stained. In PCR, the 145 bp target sequence of the LT1 fragment, located in the Leishmania donovani kDNA minicircle was detected using the RV1 and RV2 oligonucleotide primers. The chi-square test revealed that there was a significant relationship between the symptoms and dogs that were positive for visceral leishmaniasis (VL. The parasitological investigation showed concordance of 66.7% with PCR on blood and 84.1% with PCR on lymph node aspirate. In addition to these tests, evaluations of the diagnoses in parallel and in series were conducted, which showed concordances with the parasitological test of 76.2% and 74.6%, respectively. The results make it possible to suggest that PCR on lymph nodes should be used in evaluating large populations (surveys and that the parasitological test should be used for initial clinical evaluations in veterinary consultation offices.Avaliou-se a ocorrência de Leishmania infantum em cães do município de Palmas-TO, comparando dados diagnósticos obtidos pela Reação em Cadeia da Polimerase (PCR e pelo diagnóstico parasitológico.

    Full Text Available El óxido de estaño en forma de SnO2 (casiterita ha sido usado como catalizador en diferentes procesos de interés de la industria química, tales como la de deshidrogenación, cracking, isomerización y oxidación de hidrocarburos. En este trabajo se estudió la aplicación de SnO2 como catalizador y como soporte de especies de níquel y estaño, en la alcohólisis del aceite de palma. La obtención del SnO2 se realizó por el método de precipitación y la incorporación de níquel y estaño, al soporte, por el método de impregnación. Se determinó que el SnO2 presentaba una mayor actividad frente a la reacción de alcohólisis en comparación con otros óxidos, tal como el MgO, y que esta actividad era afectada por la adición de níquel y estaño en su superficie. Se utilizó cromatografía de gases CG para el seguimiento de las reacciones, así como la espectroscopia FTIR para realizar el análisis de los productos obtenidos después del proceso. Los catalizadores fueron analizados por DRX para la determinación de las fases cristalinas presentes y del análisis de área superficial, volumen y tamaño de poro, para determinar las propiedades texturales de los catalizadores.

  5. Whole-system metabolism and CO2 fluxes in a Mediterranean Bay dominated by seagrass beds (Palma Bay, NW Mediterranean

    F. Gazeau

    2005-01-01

    Full Text Available Planktonic and benthic incubations (bare and Posidonia oceanica vegetated sediments were performed at monthly intervals from March 2001 to October 2002 in a seagrass vegetated area of the Bay of Palma (Mallorca, Spain. Results showed a contrast between the planktonic compartment, which was on average near metabolic balance (−4.6±5.9 mmol O2 m-2 d-1 and the benthic compartment, which was autotrophic (17.6±8.5 mmol O2 m-2 d-1. During two cruises in March and June 2002, planktonic and benthic incubations were performed at several stations in the bay to estimate the whole-system metabolism and to examine its relationship with partial pressure of CO2 (pCO2 and apparent oxygen utilisation (AOU spatial patterns. Moreover, during the second cruise, when the residence time of water was long enough, net ecosystem production (NEP estimates based on incubations were compared, over the Posidonia oceanica meadow, to rates derived from dissolved inorganic carbon (DIC and oxygen (O2 mass balance budgets. These budgets provided NEP estimates in fair agreement with those derived from direct metabolic estimates based on incubated samples over the Posidonia oceanica meadow. Whereas the seagrass community was autotrophic, the excess organic carbon production therein could only balance the planktonic heterotrophy in shallow waters relative to the maximum depth of the bay (55 m. This generated a horizontal gradient from autotrophic or balanced communities in the shallow seagrass-covered areas, to strongly heterotrophic communities in deeper areas of the bay. It seems therefore that, on an annual scale in the whole bay, the organic matter production by the Posidonia oceanica may not be sufficient to fully compensate the heterotrophy of the planktonic compartment, which may require external organic carbon inputs, most likely from land.

  6. [Displacements of the green iguana (Iguana iguana) (Squamata: Iguanidae) during the dry season in La Palma, Veracruz, Mexico].

    Morales-Mávil, Jorge E; Vogt, Richard C; Gadsden-Esparza, Héctor

    2007-06-01

    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; p<0.05). Breeding males defended their home range vigorously against other adult males. We observed one separate male home range and large portions of overlap between the sexes. The home range generally formed a conglomerate of polygons and only two had linear shapes along the river: apparently iguanas 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. PMID:19069782

  7. Assessment of environmentally available metals in sediment samples from water for public supply of the city of Palmas, Tocantis, Brazil

    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 HNO3 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.

  10. [Genetic diversity and kin relationships among wild and cultivated populations of the pejibaye palm (Bactris gasipaes, Palmae) using microsatellite markers].

    Ugalde, José Alfredo Hernández; Urpí, Jorge Mora; Nuñez, Oscar Rocha

    2008-03-01

    Genetic diversity and kin relationships among wild and cultivated populations of the pejibaye palm (Bactris gasipaes, Palmae) using microsatellite markers. The genetic diversity of the peach palm (Pejibaye, Bactris gasipaes Kunth) was evaluated using four nuclear DNA microsatellites in an effort to elucidate the evolution and domestication of this crop. A total of 258 samples from seven wild populations and eleven races were analyzed. All loci were polymorphic and a total of 50 alleles were identified. Average genetic diversity (0.67) and genetic differentiation among populations (Fst=0.16) were high when all populations were considered. Genetic differentiation was lower when the populations were grouped according to their origin into Western and Eastern populations (Fst=0.13 for both). Gene flow was slightly higher among Western populations (Nm=1.71) than among Eastern populations (Nm=1.62). The Putumayo, Yurimaguas, Vaupés, Tucurrique and Guatuso races seem to have been subjected to intense human selection. Hybrid populations exist in Azuero, Tuira, Cauca, Vaupés, Puerto Ayacucho and Solimões, probably resulting from exchange and introgressions among sympatric wild and cultivated populations. Genetic distance (Dm) was estimated to determine the degree of relationship among populations using the neighbor-joining method; the wild populations from Maracaibo were used as the outgroup. The populations were divided into three general groups: Maracaibo (B. caribaea, B. macana var veragua and B. macana var arapuey), Eastern Amazon (Tembe, Pará and Acre) and a third group with two subgroups, Western (Azuero, Chontilla, Tuira, Cauca, Tucurrique and Guatuso) and Upper Amazon (B. dahlgreniana, Puerto Ayacucho, Solimões, Vaupés and Putumayo). The genetic relationships strongly support the hypothesis that peach palm was brought into cultivation independently in no less than three areas: the Western Andes (extending into lower Central America); Upper Amazon (extending

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

    Guetschow, H. A.; Nelson, B. K.

    2002-12-01

    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

  18. Post-fire soil erosion on vineyards and canary pine-stands on the subtropical island of La Palma: scope of application of TLS?

    Umstaedter, Kathrin; Haas, Florian; Becht, Michael

    2013-04-01

    Land use is considered as a main factor regarding post-fire soil erosion. Especially in the subtropical climate with extreme rainfall events in winter and drought periods during summer times, soil erosion can clearly exceed the soil reproduction rate. On the Canary Island of La Palma frequent wildfires and steep slopes contribute to a high likelihood of post-fire soil erosion. For a quantitative measurement of the erosion rate a terrestrial Laser Scanner with high resolution in combination with a dGPS is used. The main target of this study is to quantify the post-fire soil erosion rates on study sites with a different land use on the island of La Palma (Canary Islands). The investigation focuses on two land use forms; both are very common and widespread on the island: canary pine stands and vineyard areas. The study sites are characterized by a varying steepness, a different fire history (wildfires in 2000, 2009 and 2012) and different stages of soil development. Both denudation and gully erosion processes are spread over the sites. Intense precipitation events can trigger debris flows and extensive soil erosion on post-fire sites, like in the year 2009 in the south or in 2012 on the west and east side of La Palma. Regarding that, erosion is not just a problem for agriculture, but for the infrastructure. For our project we assume, that different topography, different land use and different forest fire history can result in a different soil erosion rate and type (gully incision, denudation processes). To calculate the post-fire erosion rates of the two land use forms, 24 study sites - 10 sites in vineyard areas, 14 in canary pines stands - were selected. By means of a 3D terrestrial Laser Scanner (Riegl LMS Z420i), high resolution digital terrain models of the study sites were compiled. The data acquisition was carried out in October 2011, May 2012 and December 2012 and subsequently the terrain models were compared. With this method not only erosion rates can be

  19. Measurement of N2 fixation in Sesbania aculeata pers. and Sorghum bicolor L. grown in intercropping system, using sup 1 sup 5 N isotopic dilution technique. 1: Field evaluation under non-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 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.

    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.

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

    2014-01-01

    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.

  9. Testing the Palma-Clary Reduced Dimensionality Model Using Classical Mechanics on the CH4 + H → CH3 + H2 Reaction.

    Vikár, Anna; Nagy, Tibor; Lendvay, György

    2016-07-14

    Application of exact quantum scattering methods in theoretical reaction dynamics of bimolecular reactions is limited by the complexity of the equations of nuclear motion to be solved. Simplification is often achieved by reducing the number of degrees of freedom to be explicitly handled by freezing the less important spectator modes. The reaction cross sections obtained in reduced-dimensionality (RD) quantum scattering methods can be used in the calculation of rate coefficients, but their physical meaning is limited. The accurate test of the performance of a reduced-dimensionality method would be a comparison of the RD cross sections with those obtained in accurate full-dimensional (FD) calculations, which is not feasible because of the lack of complete full-dimensional results. However, classical mechanics allows one to perform reaction dynamics calculations using both the RD and the FD model. In this paper, an RD versus FD comparison is made for the 8-dimensional Palma-Clary model on the example of four isotopologs of the CH4 + H → CH3 + H2 reaction, which has 12 internal dimensions. In the Palma-Clary model, the only restriction is that the methyl group is confined to maintain C3v symmetry. Both RD and FD opacity and excitation functions as well as differential cross sections were calculated using the quasiclassical trajectory method. The initial reactant separation has been handled according to our one-period averaging method [ Nagy et al. J. Chem. Phys. 2016, 144, 014104 ]. The RD and FD excitation functions were found to be close to each other for some isotopologs, but in general, the RD reactivity parameters are lower than the FD reactivity parameters beyond statistical error, and for one of the isotopologs, the deviation is significant. This indicates that the goodness of RD cross sections cannot be taken for granted. PMID:26918703

    Full Text Available Inside the talayotic complex known as So n'Oms, in the municipal area of Palma (Mallorca, Balearic Islands, there is a sanctuary excavated in the sixties which produced an ample series of thin walled pottery that were dedicated as offerings to the gods. All the material found can be dated between 20-10 a.C.-. and 50 d.C. It is so well preserved that it has been possible to recognise and determine decoration and paste and, therefore, to reach to the conclusion that most of them belongs to production centers situated in Mallorca and Ibiza (from this last almost the 70%. There are, also, italic and betican productions.Dentro del conjunto talayótico conocido como So n'Oms, situado en el término municipal de Palma (Mallorca, islas Baleares, existe un santuario excavado en la década de los sesenta, que proporcionó un extenso lote de cerámica de paredes finas, depositadas allí como ofrenda. Los materiales pueden situarse entre los años 20/10 a.C. y 50 de nuestra era. Destaca su buen estado de conservación, que ha permitido un reconocimiento minucioso de pastas y decoraciones, habiéndose podido atribuir una gran parte de las piezas a centros productores de Mallorca y sobre todo —más del 70 %— de Ibiza. También se han localizado vasos héticos e itálicos.

    Full Text Available The main objective of this paper was to establish an inventory of the Federal University of Tocantins’Greenhouse Gases (GHGs emissions derived from controlled sources and administrative activities conducted in 2009 by the Rectory and the University Campus of Palmas, in order to calculate the number of Savanna’s native trees to be planted in the region of the county of Palmas-TO to neutralize GHG emissions reported in carbon dioxide equivalent (CO2e. Utilizing the Specifications of the Brazilian Program GHG (Greenhouse Gas Protocol for this purpose associated with the calculus methodologies of GHG emissions published by the Intergovernmental Panel on Climate Change (IPCC for the completion of the inventory, as well as using the Good Practice Guide for Land Use, Land-Use Change and Forestry (LULUCF published by the IPCC forneutralization of CO2e calculus. The inventory result showed that the listed units emitted around 218tCO2e and for its neutralization, it would be necessary to plant approximately 1.702 trees for sequestering all CO2e over a period of 20 years. The methodologies used for the composition of the GHG inventory came up as excellent tools for determining the emission profile. Despite the uncertainties about the carbon fixation rate, it can be used to calculate the neutralization of GHG as a way of environmental mitigation.

    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. The reaction rate was increased with the increment of the impeller rotational speed as well as increasing the lipase concentration. Although the literature cites bleaching as a beneficial advantages to enzymatic hydrolysis, this procedure do not have a significant beneficial effect on the reaction.

Aunque conocida como emanación de aquella magna encuesta, la documentación base de este trabajo aún está, sin embargo, muy poco explotada desde la triple perspectiva que lo intitula, y que hay que analizar y entender en el contexto de un Estado cada vez más necesitado de saber, fiscalizar y controlar a sus súbditos para gobernar, como fue, en definitiva, el ilustrado. Para el logro de nuestros objetivos y la comprensión del texto básicos son cuantificación y aparato estadístico subsiguiente. Finalmente, este primer acercamiento presenta un estado más lineal de conocimientos sobre la realidad local que explora, que se aquilata en otra fase posterior con el análisis específico y selectivo de las distintas variables que ahora sólo se examinan básicamente, o con su entrecruzamiento.

    Full Text Available This paper is the first result of an agreement between the Organismo Autónomo Parques Nacionales and the Consejo Superior de Investigaciones Científicas, entitled “Inventory and study of the Invertebrate Fauna of the National Park of La Caldera de Taburiente”. A detailed account of the faunistic novelties found up to now among the specimens of terrestrial and freshwater invertebrates collected along the two years of sampling (July 1999 to July 2001, whose number is estimated in ca. 500,000, is given. A brief description of planning and of methodology applied to the inventory of the invertebrate fauna is made and a tabulated summary of novelties is presented. The list shows at present 284 families, 594 genera and 739 species. For the Canary Islands, the present record of new taxa is 29 families, 115 genera (1 of them confirmed as new to Science and 3 awaiting confirmation and 187 species (24 new to Science. Moreover, 242 genera and 338 species are new to the fauna of La Palma I., being known from other islands of the archipelago. Other 47 taxa, still being studied, could be new to Science as well. These results have been reached with the study of just a minimal part of the whole material, which underlines the need for systematic, continued sampling to evaluate the faunistic richness of poorly explored areas and its possible necessity for protection. Therefore, one should expect more novelties and the inventory may increase significantly when all the material is revised.

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. Luego la concentración de PA aumenta hasta el estado de Buena Recuperación donde los valores de poliaminas son más altos que los de palmas sanas. En la ZOCC , el contenido de PA aumenta con la enfermedad llegando al máximo en plantas sin recuperación y el mínimo en plantas sanas. Las diferencias entre zonas pueden explicarse por los 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 ZOCC el aumento en el contenido de PA con la enfermedad puede estar relacionado con la producción de especies reactivas de oxigeno para defensa secundaria contra patógenos. A diferencia de lo observado en ZC , las plantas en ZOCC no pueden producir estructuras sanas que no sean re infectadas, por lo tanto los elevados contenidos de PA no están relacionados con la promoción de la actividad meristemáticaBud Rot complex (BR is the major disease of oil palm in Colombia .

    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.

    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  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 (2005,2006, 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.  Variación demográfica temporal de la tortuga de río chocoana, Rhinoclemmys nasuta (Geoemydidae, en Isla Palma, Bahía Málaga, Pacífico del Valle del CaucaPocos 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.

    In their pioneering work, Ward and Day suggested that a large scale flank collapse of the Cumbre Vieja Volcano (CVV) on La Palma (Canary Islands) could trigger a mega-tsunami throughout the North Atlantic Ocean basin, causing major coastal impact in the far-field. While more recent studies indicate that near-field waves from such a collapse would be more moderate than originally predicted by Ward and Day [Løvholt et al. (J Geophy Res 113:C09026, 2008); Abadie et al. (J Geophy Res 117:C05030, 2012)], these would still be formidable and devastate the Canary Island, while causing major impact in the far-field at many locations along the western European, African, and the US east coasts. Abadie et al. (J Geophy Res 117:C05030, 2012) simulated tsunami generation and near-field tsunami impact from a few CVV subaerial slide scenarios, with volumes ranging from 20 to 450 km^3; the latter representing the most extreme scenario proposed by Ward and Day. They modeled tsunami generation, i.e., the tsunami source, using THETIS, a 3D Navier-Stokes (NS) multi-fluid VOF model, in which slide material was considered as a nearly inviscid heavy fluid. Near-field tsunami impact was then simulated for each source using FUNWAVE-TVD, a dispersive and fully nonlinear long wave Boussinesq model [ Shi et al. (Ocean Modell 43-44:36-51, 2012); Kirby et al. (Ocean Modeling, 62:39-55, 2013)]. Here, using FUNWAVE-TVD for a series of nested grids of increasingly fine resolution, we model and analyze far-field tsunami impact from two of Abadie et al.'s extreme CVV flank collapse scenarios: (i) that deemed the most "credible worst case scenario" based on a slope stability analysis, with a 80 km^3 volume; and (ii) the most extreme scenario, similar to Ward and Day's, with a 450 km^3 volume. Simulations are performed using a one-way coupling scheme in between two given levels of nested grids. Based on the simulation results, the overall tsunami impact is first assessed in terms of maximum surface

O delineamento foi em blocos casualizados, com três repetições. Os tratamentos foram 19 clones de palma do Banco de Germoplasma do IPA. Foram mensuradas: a medidas em artículos, conforme a ordem: comprimento, largura, espessura, número e peso da matéria verde. b medidas por planta: presença de espinho, número de artículos por ordem e total, altura total, infestação por cochonilha e peso da matéria verde. Realizaram-se análises de variância univariada (ANOVA e multivariada (MANOVA, das variáveis canônicas (VC e de agrupamento (AA. Na ANOVA, foi verificada diferença entre as médias de clones e por meio da MANOVA, diferença entre vetores de médias de clones. Com a aplicação da VC, foi possível reduzir a dimensionalidade original para duas dimensões, com explicação de 85,03% da variação total. Foi considerada, como característica passível de descarte, a porcentagem de infestação por cochonilha. Na AA discriminaram-se nove grupos. A característica porcentagem de infestação por cochonilha não deve ser incluída no estudo da diversidade genética nas condições estudadas. As características de maior discriminação foram espessuras dos artículos primário, secundário e terciário, número de artículo primário e pesos médios de matéria verde por artículos secundário e terciário. Em um programa de melhoramento de palma forrageira, devem-se considerar o grupo de clones e o desempenho do clone quanto às características de maior relevância agronômica e zootécnica.

El estudio mostró que el acceso de la comunidad a semillas provenientes del sistema formal es escaso, por lo que la producción, selección y conservación de semillas es realizada por los campesinos en sus propias fincas y el intercambio ocurre entre los propios campesinos, los que siembran variedades y/o clones locales, los cuales presentan cierta resistencia a las plagas y enfrermedades presentes en la últica década. Este estudio señala la necesidad de un flujo nuevo y constante de genes, que brinde la posibilidad a los campesinos de acceder a nuevas variedades y seleccionar aquellas con características de adaptabilidad a las condiciones específicas de cada localidad.

  13. Diversificación de productos y segmentación de la demanda turística en la isla de La Palma: aplicaciones de cara a la política turística

    Díaz Pérez, Flora M

    2003-01-01

    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

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.

    2011-11-01

    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.

    2016-01-01

    for > 200 years. We tested the impact of cattle on spinescence and abundance of four common palm species (three armed: Acrocomia aculeata, Bactris glaucescens, Copernicia alba; one unarmed: Attalea phalerata), comparing areas with cattle to areas free of cattle for 30 years. We measured spine length...... and density on leaves and stems and the abundances of different life stages. In all armed species, leaf spine length and density increased with cattle presence, suggesting strong responses to megafauna herbivory by increasing investment in anti-herbivory defence. Weaker non-significant trends were observed...... for stem spinescence, perhaps reflecting a lower susceptibility of stems to herbivore damage. In three of four species, the abundances of seedlings and juveniles (but not adults) were reduced in areas with cattle. We conclude that armed palm species have most probably retained an adaptive capacity...

  17. Phytotoxic and antioxidant activity of seven native fruits of Brazil

    Marize Terezinha Lopes Pereira Peres

    2013-12-01

    Full Text Available We investigated antioxidant capacity, phenolic content and phytotoxic effects in seven species of fruit native to Brazil: Acrocomia aculeata, Hymenaea stigonocarpa, Tamarindus indica, Byrsonima intermedia, Psidium firmum, Myrciaria cauliflora and Ficus obtusifolia. Phytotoxic effects were assessed from crude ethanol extracts and semipurified fractions. In four of the seven fruits, total phenolic content, as determined by Folin-Ciocalteu assay, was higher in the peel than in the pulp. We found that total phenolic content correlated significantly with antioxidant capacity. High-performance liquid chromatography with diode array detection revealed the presence of the flavonoids quercetin and rutin in some fruits. We also evaluated the allelopathic effects of the crude ethanol extract and semipurified fractions. In most of the essays, the ethyl acetate fractions showed the highest level of activity.

    2014-05-01

    In this study, we described the food plants available to Blue-and-Yellow Macaws (Ara ararauna), its feeding habits and the relationship between these parameters with feeding niche breadth. We established four transects, each one 12 km long, to sample fruiting plants and the feeding habits of this macaw (monthly 40 h, of observations), at the urban areas of Três Lagoas (Mato Grosso do Sul, Brazil). During all studied months, macaws foraged for palm fruits, mainly Syagrus oleracea and Acrocomia aculeata fruit pulp, both available all year, as well as Caryocar brasiliense and Anacardium occidentale seeds, in the wet season. The year-round feeding activity of macaws suggests Três Lagoas city as an adequate feeding area. The permanent availability of plant food resources, potentially, resulted from the diverse fruiting patterns of exotic and, mainly, native plant species, which provided a variety of suitable fruit patches.

    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. As crianças com EBICT realizaram single photon emission computed tomography (SPECT interictal e Teste de Desempenho Escolar (TDE. Foram encontradas diferenças significativas entre os dois grupos nas atividades motoras de três movimentos iguais e três movimentos diferentes. As crianças com piores resultados no TDE e com SPECT alterado apresentaram mais erros no teste de imitação manual. Crianças com epilepsia fracassaram nos testes de avaliação motora que envolvem programação/planejamento. Esse estudo sugere que mudanças funcionais relacionadas à atividade epileptiforme na região rolândica interfere com as funções executivas de crianças com EBICT.

    Full Text Available Capuchin monkeys occupy a wide range of habitats where they feed on fruits, arthropods, and vertebrates. Their large home ranges (80-900 ha suggest that living in forest fragments may challenge their adaptability. We identified and quantified the main food items of Cebus libidinosus Spix, 1823 in forests fragments (100 ha in southeastern Brazil. We recorded the feeding activities of two groups using scan sampling over a 13-month period. The diet was composed of fruits, crops, animal prey, seeds, plant matter and undetermined. Fruit was eaten more in the wet season than in the dry season, and maize and sugar cane consumption peaked in the early dry season. The proportion of fruit in the diet was positively correlated with fruiting intensity of zoochorous trees. The plant diet included 54 species, with maize, Rhamnidium elaeocarpus, Acrocomia aculeata, Guazuma ulmifolia and Cariniana, being most important. Although dietary composition and diversity were similar to capuchins in larger forest fragments, feeding on crops attained higher percentages at times when zoochorous fruit production was low in fragments.Macacos-prego ocupam uma vasta gama de ambientes onde alimentam-se de frutos, artrópodes e vertebrados.

    2015-01-01

    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 housi...

    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.

    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)

    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. PMID:27169570

    Full Text Available ABSTRACT The macaw palm [Acrocomia aculeata (Jacq. Lood. ex Mart] has been domesticated to subsidize biodiesel production programs in Brazil. However, little is known about the seedling production of this species. This study aimed to evaluate substrate mixtures, limestone and phosphorus rates for substrate amendment and topdressing frequency in macaw palm seedlings. Three trials were conducted in a greenhouse up to six months of nursery cultivation. Trial 1: determination of percent mineral and organic fractions of seven substrate mixtures. Trial 2: evaluation of four limerates for soil amendment versus four phosphorus rates. Trial 3: evaluation of N, K and Mg topdressing frequency. Significant differences were found in the three trials for most of the variables (plant height, leaf number, shoot dry mass, root dry mass, vigor and bulb diameter. The main results obtained were as follow: Trial1 - the best seedling growth was observed in substrates with at least 25% organic matter. Trial2 -lime rates ranging from 0.50 to 1.25 kg associated with 3 to 4 kg of single superphosphate per m3 of substrate provided the best seedling growth. Trial 3 - topdressing fertilization provided better development of seedlings regardless of frequency.

    2015-06-01

    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.

    1995-01-01

    Cooked and uncooked samples from four pejibaye palm races were analyzed to determine the moisture content, ether extract and the content of six fatty acids (C16:0 to C18:3). There was an increase in moisture and a decrease in ether extract (p < 0.05) in the cooked samples in comparison with the uncooked ones. No significant differences were found in fatty acid content between cooked and uncooked samples, but there were differences (p < 0.05) among races concerning the content of four fatty acids. Pejibaye fat is mainly mono-unsaturated (45.6%) and has a low poly-unsaturated to saturated fatty acid ratio (0.5). The fatty acid profile of uncooked pejibaye samples was: oleic acid, 32.6 to 47.8%; palmitic acid, 30.5 to 40.3%; linoleic acid, 11.2 to 21.1%; palmitoleic acid, 5.7 to 7.1%; linoleic acid, 1.5 to 5.5%; and stearic acid, 1.7 to 2.4%.

  6. Pollution bi nitrate in the urban and rural zone of Macachins town, La Palma, Argentina

    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.

    The wax hydrocarbon fractions of native Butia and Syagrus species collected from Palms in different regions of the of Rio Grande do Sul state (Brazil) and in Rocha (Uruguay) were analyzed to evaluate their potential as chemotaxonomic markers. The wax was extracted with chloroform and the resulting wax was fractionated by preparative TLC. The hydrocarbon fractions were analyzed by GC-MS. Statistical analyses were completed with the Statistica 5.0 program. The total crude wax yields averaged 0.31% w.w-1 dried leaves for Butia samples and 0.28% for Syagrus samples. The linear hydrocarbons represented on average 15% of the total waxes in the case of Butia samples and 13.7% in Syagrus samples. Hentriacontane and triacontane were the main components of all samples. The comparison of the means showed significant differences among Butia and Syagrus samples, and amongst Butia samples collected in different localities. In the case of the Syagrus collections no consistent groupings could be made. In the case of Butia samples the formation of three groupings could be observed, which were consistent with the species described for their geographical distribution. These results are discussed in the paper. PMID:19675938

  13. Sexual reproduction and clonal growth in Reinhardtia gracilis (Palmae), an understory tropical palm.

    Mendoza, A; Franco, M

    1998-04-01

    Patterns of sexual reproduction and clonal growth were investigated in the understory palm Reinhardtia gracilis var. gracilior over a 3-yr period. R. gracilis is a very abundant clonal palm in the tropical rain forest of Los Tuxtlas, Veracruz, México. Because ramets form clumps, genets are easily identified in the field. Genets were monitored in a 0.5-ha area, and classified by size according to the number of ramets they possessed. In contrast to clonal growth, sexual reproduction was highly dependent on genet size. The probability of reproduction, the number of inflorescences, and the number of fruits produced were positively correlated with genet size. However, neither the probability of producing a ramet, nor the number of ramets produced per genet were correlated with genet size. Over the 3 yr of study, 55% of the genet population had at least one ramet with reproductive structures, while <1% (a single genet in one year) had six ramets with flowers. Thirty-two percent of the mature genets reproduced during each of three consecutive years. In contrast, 58% of the genets produced no new ramets during these 3 yr. No evidence was found of a trade-off between clonal growth and sexual reproduction. Ramet production increases genet size and this in turn increases genet reproductive performance. Clonal growth in this species may be viewed as a growth strategy that tends to maximize genet fitness. PMID:21684935

    A amêndoa de macaúba (Acrocomia aculeata (Jacq. Lodd. tem despertado grande interesse socio-econômico para a população do Cerrado e possui propriedades nutricionais pouco estudadas. O objetivo deste estudo foi caracterizar físico-quimicamente a amêndoa de macaúba e verifi car o valor nutricional e a aceitabilidade de uma barra de cereais elaborada a partir deste material. Os frutos coletados foram lavados, sanitizados, secos e suas amêndoas foram retiradas. As características físico-químicas das amêndoas avaliadas foram massa, diâmetro, pH, SST, ATT e composição centesimal. Elaborou-se uma barra de cereais teste com adição de 15% do fruto e uma controle e determinou-se suas composições centesimais. A avaliação sensorial das formulações foi realizada com 45 participantes em três etapas: teste de aceitação (escala de 5 pontos, teste de preferência e análise descritiva quantitativa (aparência, cor, aroma, sabor, textura e doçura dos produtos. As amêndoas de macaúba estudadas possuem quantidades expressivas de lipídios (29,73%, proteínas (12,28% e energia (524,19kcal/100g. A barra de cereais com macaúba obteve maiores teores de lipídios (7,84% e energia (396,28kcal/100g. O índice de aceitação da barra de cereais formulada com macaúba foi de 88,90% e o teste de preferência evidenciou 71,11% de aprovação pelos participantes da pesquisa. A barra teste obteve atributos mais bem aceitos em relação à controle (p<0,05, na qual o atributo “sabor” alcançou a maior pontuação média (4,62. Dessa forma, conclui-se que as características físico-químicas da amêndoa de macaúba contribuem de forma positiva para a elaboração de barras de cereais, conferindo ao produto final um perfil sensorial de boa aceitabilidade.

    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. Thus, the higher CP macauba leaves

    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.

    2010-01-01

    The Observatorio del Roque de los Muchachos (ORM), in the Canary Islands (Spain), was one of the candidates to host the future European Extremely Large Telescope (E-ELT) and is the site of the Gran Telescopio Canarias (GTC), the largest optical infrared facility to date. Sky transparency is a key parameter as it defines the quality of the photometry to be acquired in the astronomical observations. We present a study of the atmosphere extinction at the ORM, carried out after analysis of a database spanning more than 20 yr, to our knowledge, the longest and most complete and homogeneous in situ database available for any observatory. It is based on photometric measurements in the V band and r' band (transformed to the V -band extinction coefficient kV) using the Carlsberg Meridian Telescope (CMT). Clear seasonal variations that repeat yearly are observed. The median value of kV is 0.13 mag/airmass; the mean value has a maximum in the summer months (June- September), corresponding to the season with maximum freq...

    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.

  10. Palma de aceite y desplazamiento forzado en Zona Bananera: “trayectorias” entre recursos naturales y conflicto.

    Juanita Goebertus Estrada.

    2008-06-01

    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 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 Se estandarizó un sistema de electroforesis de isoenzimas con tejido de hojas que permitió la identificación del polimorfismo fenético entre cuatro razas y un híbrido de pejibaye Bactris gasipaes provenientes de Brasil, Perú, Bolivia, Panamá y Costa Rica. Las isoenzimas ensayadas fueron: PRX, EST, ACP, ME, DIA, MDH, G6PDH, PGI, SOD, PGM, ADH, GOT, de estas solamente las dos œltimas no mostraron actividad. El resto de isoenzimas mostraron polimorfismo fenético en diferentes grados, por esto se consideran marcadores polimórficos potenciales para estudios de variabilidad genética en pejibaye. Se encontró un locus único en el zimograma de la enzima PRX en las muestras de Utilis-Guápiles (CR, el cual podría usarse como un marcador discriminatorio para esta raza. Se establecieron relaciones de similitud isoenzimática entre las razas Utilis-Guápiles (CR y Tuira-Darién (Pa; Tembé-Chapare (Bo y Pará-Belem (Bra respectivamente, mientras que el híbrido Yurimaguas (Pe se ubicó aparte y ligeramente más cercano a Utilis y Tuira, por esto se considera que posiblemente desciende de padres aún no identificados.The study of genetic diversity in peach palm (Bactris gasipaes K. is important for the breeding work on this palm and to corroborate the hypotheses on its origins. For that purpose it is necessary to use alternative techniques to complement the morphological studies traditionally made. One of the techniques that responds to that need is isozyme electrophoresis. 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.

    2012-07-01

    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.

    Full Text Available The Balearic Demographic Transition has been considered a forerunner in the Spanish context due to a high life expectancy of 42 years in the decade of 1860, owing primarily to low infant mortality. For a more in-depth evaluation of the factors behind this exceptional health situation, we analyze the role played by Hygienism in the decline of mortality due to the Infant Welfare movement and Public Health reforms that took place at the end of the 19th century and in the first decades of the 20th century. Both processes were led by a variety of community stakeholders such as physicians, engineers, nuns, lawyers, as evidence of a social consensus in the condemning the so-called ‘avoidable’ causes of disease and death.

    El avanzado modelo balear de Transición Demográfica se documenta por una elevada esperanza de vida al nacer —de casi 42 años en la década de 1860— como resultado de una baja mortalidad infantil. Con el propósito de ahondar en las razones de esta situación sanitaria privilegiada se ha analizado la influencia del Higienismo sobre el descenso de la mortalidad. Para ello se ha examinado el movimiento puericultor y la reforma sanitaria de finales del siglo XIX y primeras décadas del siglo XX. Se trata de un conjunto de actividades cuya responsabilidad fue compartida por diversos actores sociales, desde médicos, abogados e ingenieros, a monjas u otros colectivos que permite pensar en la existencia de un consenso social en la denuncia de las causas ‘evitables’ de enfermedad y muerte.

    2015-06-01

    Based on a measuring campaign which was carried out at Mallorca (39.6°N, 2.7°E) as cooperation between Agència Estatal de Meteorologia (AEMET) and Deutsches Zentrum für Luft- und Raumfahrt, engl. 'German Aerospace Center' (DLR) in 2011/2012 (September-January), 143 radiosondes (day and night) providing vertical temperature and wind profiles were released. Additionally, nocturnal mesopause temperature measurements with a temporal resolution of about 1 min were conducted by the infrared (IR) - Ground-based Infrared P-branch Spectrometer (GRIPS) during the campaign period. Strongly enhanced gravity wave activity in the lower stratosphere is observed which can be attributed to a hurricane-like storm (so-called Medicane) and to passing by cold fronts. Statistical features of gravity wave parameters including energy densitiy and momentum fluxes are calculated. Gravity wave momentum fluxes turned out being up to five times larger during severe weather. Moreover, gravity wave horizontal propagation characteristics are derived applying hodograph and Stokes parameter analysis. Preferred directions are of southeast and northwest due to prevailing wind directions at Mallorca.

    Full Text Available Oil palm cultivars come from four oil palms located at Bogor´s botanical garden. However, experimental evidence suggests that the centre of origin of the oil palm, Elaeis guineensis Jacq., is the African continent. In order to develop oil palm cultivars in Colombia, it is necessary to increase the narrow genetic base currently available. For this reason, Cenipalma carried out prospections and collections of oil palm material in five natural regions of the Republic of Angola. Around 44 accessions (120 seeds per accession were collected, seeds were germinated and young palms were grown under field conditions at the Experimental Station Palmar de La Vizcaína (Barrancabermeja. In this paper, we report results of the molecular analysis, based in amplification of 16 microsatellite loci, of 72 genotypes, representing five populations, from Cenipalma´s E. guineensis germplasm collection. Evaluated plants showed a higher genetic variability when compared to similar studies on this species, although populations displayed high similarity (low genetic differentiation, FST=0,0484. The high similarity between individuals of the different species allows representing the full variation by selecting few individuals. Variability and genetic differentiation measurements are presented.

    2014-12-01

    Full Text Available Oil palm Elaeis guineesis Jacq. is of great importance because of the oil extracted from its fruits, whose refined derivatives are commercially valuable as biodiesel, among others uses. This study sought to determine the structure and genetic diversity of 311 oil palm samples from the Republic of Cameroon with 10 microsatellite markers. The results showed values for the average number of alleles per locus of Na= 8.433 and effective number of alleles per locus of Ne= 4.756; from the differences between these values, it can be inferred that the 106 alleles found for these populations could be considered rare alleles. Additionally the value of genetic diversity was high (mean value of He= 0.781 compared to reports of several authors. The obtained molecular variance showed that the highest percentage (80 % was found within the individuals. The analysis did not show any defined population structure, which allowed us to infer a high gene flow among the geographic zones, corroborated it by the high genetic diversity values obtained. The 311 genotypes were defined as a heterogeneous heterozygous natural population suitable to increase the genetic base of oil palm cultivated populations.

    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.

    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.

    Full Text Available Objetivou-se investigar o efeito do extrato acetato de etila de Cocos nucifera (EAECN sobre parâmetros fisiológicos e sobre a inflamação tópica induzida por xileno. 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.

    2008-01-01

    Los riegos se realizaron en dos momentos y el experimento se mantuvo libre de plantas fuera de lugar. Se aplicó una encuesta a los 83 campesinos participantes en el proceso de selección, para colectar información acerca de los criterios más importantes para ellos y, al mismo tiempo, se evaluaron 20 descriptores, entre los que se encontraban el rendimiento y sus componentes, la susceptibilidad al gorgojo y altura de la planta. Como complemento a los datos registrados, se realizaron entrevistas individuales a campesinos seleccionadores, para profundizar en las bases del conocimiento del proceso de selección practicado. Para el procesamiento de los datos se utilizó el análisis de proporciones, la correlación no paramétrica (Kendall y representaciones gráficas. Se encontró que los campesinos eligen sus variedades por 'correlación práctica', auxiliándose de caracteres cualitativos, como los marcadores biológicos de su objetivo principal y la resistencia a los insectos en poscosecha. El carácter "forma de la mazorca" es el criterio de selección más importante en este sistema de producción de maíz.

    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.

    2014-12-01

    The chemical composition of the essential oils of Pereskia aculeata Mill. and P. grandifolia Haw. (Cactaceae), grown in Brazil, was studied by means of GC and GC-MS. In all, 37 compounds were identified, 30 for P. aculeata and 15 for P. grandifolia. Oxygenated diterpenes are the main constituents, both in the oil ofP. grandifolia (55.5%) and in that ofP. aculeata (29.4%). The essential oils were evaluated for their in vitro phytotoxic activity against germination and initial radicle growth of Raphanus sativus L., Sinapis arvensis L., and Phalaris canariensis L. seeds. The essential oil of P. grandifolia, at all doses tested, significantly inhibited the radicle elongation of R. sativus. Moreover, the antimicrobial activity of the essential oils was assayed against ten bacterial strains. The essential oils showed weak inhibitory activity against the Gram-positive pathogens.

  14. Influence of the deep fat frying process on the lipid profile of the fat contained in the french type fried potato using palm olein; Influencia del proceso de fritura en profundidad sobre el perfil lipidico de la grasa contenida en patatas tipo french, empleando oleina de palma

    Marcano, J.; Rosa, Y. la; Salinas

    2010-07-01

    The aim of this investigation was to evaluate the influence of certain variables of the process of deep fat frying on the lipid profile of the fat fraction of the potato type french (Solanum tuberosum) using palm oil. This marked the first fat fraction of both the processing type and the oil used, through the evaluation of various physicochemical parameters, using the method of AOAC and the Standard COVENIN. We identified variables that influenced the process during frying of potatoes, using an experimental design of type 3 * 2{sup 2}, evaluating factors such as the reuse of the matrix fat (1st, the 4th and the 8th fry), temperature (150 degree centigrade and 180 degree centigrade) and method of food peeling (chemical and manual), studying the content of polar compounds as an indicator of the deterioration of the fat present in the potato, finding that oil reuse and peeling method significantly influenced in a positive manner, and that the temperature has a negative influence on the absorption of polar compounds in potato chips ({alpha}: 0.05).

    Poot-Pech, M A; Ruiz-Sánchez, E; Ballina-Gómez, H S; Gamboa-Angulo, M M; Reyes-Ramírez, A

    2016-08-01

    The Central American locust (CAL) Schistocerca piceifrons piceifrons Walker is one of the most harmful plant pests in the Yucatan Peninsula, where an important gregarious zone is located. The olfactory response and host plant acceptance by the CAL have not been studied in detail thus far. In this work, the olfactory response of the CAL to odor of various plant species was evaluated using an olfactometer test system. In addition, the host plant acceptance was assessed by the consumption of leaf area. Results showed that the CAL was highly attracted to odor of Pisonia aculeata. Evaluation of host plant acceptance showed that the CAL fed on Leucaena glauca and Waltheria americana, but not on P. aculeata or Guazuma ulmifolia. Analysis of leaf thickness, and leaf content of nitrogen (N) and carbon (C) showed that the CAL was attracted to plant species with low leaf C content. PMID:26957085

  20. Effect of different water salinity levels on growth, nodulation, and N sub 2 fixation by dhaincha and on growth of sunflower using 15N tracer technique

    The effect of different salinity levels of irrigation water (ECw range 1.1 to 33 ds/m) on the nodulation, dry matter production and N2 fixation by dhaincha (Sesbania aculeata Pers.) was investigated in a pot experiment. The same effect on the growth of sunflower (Helianthus annuus L.) which was also utilized as a reference crop for measuring N2-fixation by the legume crop using the 15N-isotope dilution method, was also investigated. Irrigation with water having ECw of more than 4.03 dS/m reduced plant growth, and the reduction was more pronounced in S. aculeata than in H. annuus. High levels of water salinity caused more inhibition in shoot than in root growth of both plant species. The indigenous rhizobial strains could form nodules on Sesbania aculeata grown under different salinity levels of irrigated water, except for those irrigated with high level of ground water salinity (ECw 33 dS/m) where nodulation and N2 fixation were completely inhibited, %N2 fixation was significantly enhanced by a moderate salinity level (ECw of 4.03 dS/m) in irrigated water, whereas small effects were obtained with higher water salinity levels (up to 12.3 dS/m). The results indicated that Sesbania aculeata and helianthus annuus grown in saline soils can be irrigated either with saline water up to 8.03 dS/m and 12.3 dS/m, respectively, or with gradually increased levels of salinity for both of them.

    M. A. Miles

    1983-12-01

    Full Text Available Trypanosoma cruzi infected Rhodnius robustus and/or Rhodnius pictipes were commonly found, in large numbers, in the Brazilian Amazonian palms Maximiliana regia ("inajá", Acrocomia sclerocarpa ("mucajá" and Orbignya speciosa ("babaçu". The common opossum, Didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. R. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of Chagas' disease in the vicinity of Belém. It is considered that triatomine infested palms are likely to cause some cases of acute Chagas' disease in the States of Amazonas and Rondônia. Possible control methods are suggested.Rhodnius robustus e/ou Rhodnius pictipes, infectados com Trypanosoma cruzi foram comumente encontrados, em grande numero, nas palmeiras Maximiliana regia (inaja, Acrocomia sclerocarpa (mucaja e Orbignya speciosa (babacu na Amazonia brasileira.

  17. Plant water use characteristics of five dominant shrub species of the Lower Rio Grande Valley, Texas, USA: implications for shrubland restoration and conservation.

    Adhikari, Arjun; White, Joseph D

    2014-01-01

    The biogeographic distribution of plant species is inherently associated with the plasticity of physiological adaptations to environmental variation. For semi-arid shrublands with a legacy of saline soils, characterization of soil water-tolerant shrub species is necessary for habitat restoration given future projection of increased drought magnitude and persistence in these ecosystems. Five dominant native shrub species commonly found in the Lower Rio Grande Valley, TX, USA, were studied, namely Acacia farnesiana, Celtis ehrenbergiana, Forestiera angustifolia, Parkinsonia aculeata and Prosopis glandulosa. To simulate drought conditions, we suspended watering of healthy, greenhouse-grown plants for 4 weeks. Effects of soil salinity were also studied by dosing plants with 10% NaCl solution with suspended watering. For soil water deficit treatment, the soil water potential of P. glandulosa was the highest (-1.20 MPa), followed by A. farnesiana (-4.69 MPa), P. aculeata (-5.39 MPa), F. angustifolia (-6.20 MPa) and C. ehrenbergiana (-10.02 MPa). For the soil salinity treatment, P. glandulosa also had the highest soil water potential value (-1.60 MPa), followed by C. ehrenbergiana (-1.70 MPa), A. farnesiana (-1.84 MPa), P. aculeata (-2.04 MPa) and F. angustifolia (-6.99 MPa). Within the species, only C. ehrenbergiana and F. angustifolia for soil water deficit treatment and A. farnesiana for the salinity treatment had significantly lower soil water potential after 4 weeks of treatment (P water potential, stomatal conductance and net photosynthesis of the species significantly reduced over time for both treatments (P water availability, some species demonstrated limited tolerance for extreme water stress that may be important for management of future shrub diversity in Lower Rio Grande Valley.

    Devi, S; Nandwal, A S; Angrish, R; Arya, S S; Kumar, N; Sharma, S K

    2016-01-01

    Phytoremediation potential of six halophytic species i.e. Suaeda nudiflora, Suaeda fruticosa, Portulaca oleracea, Atriplex lentiformis, Parkinsonia aculeata and Xanthium strumarium was assessed under screen house conditions. Plants were raised at 8.0, 12.0, 16.0, and 20.0 dSm(-1) of chloride-dominated salinity. The control plants were irrigated with canal water. Sampling was done at vegetative stage (60-75 DAS). About 95 percent seed germination occurred up to 12 dSm(-1) and thereafter declined slightly. Mean plant height and dry weight plant(-1) were significantly decreased from 48.71 to 32.44 cm and from 1.73 to 0.61g plant(-1) respectively upon salinization. Na(+)/K(+) ratio (0.87 to 2.72), Na(+)/ Ca(2+) + Mg(2+) (0.48 to 1.54) and Cl(-)/SO4(2-) (0.94 to 5.04) ratio showed increasing trend. Salinity susceptibility index was found minimum in Suaeda fruticosa (0.72) and maximum in Parkinsonia aculeata (1.17). Total ionic content also declined and magnitude of decline varied from 8.51 to 18.91% at 8 dSm(-1) and 1.85 to 7.12% at 20 dSm(-1) of salinity. On the basis of phytoremediation potential Suaeda fruticosa (1170.02 mg plant(-1)), Atriplex lentiformis (777.87 mg plant(-1)) were the best salt hyperaccumulator plants whereas Xanthium strumarium (349.61 mg plant(-1)) and Parkinsonia aculeata (310.59 mg plant(-1)) were the least hyperaccumulator plants.

  14. Diversity of planktonic Ostracods (Crustacea: Ostracoda in the mixed layer of northeastern Arabian Sea during the summer monsoon

    Jasmine Purushothaman

    2015-03-01

    Full Text Available Planktonic ostracods contribute significantly to the biomass of zooplankton in the Arabian Sea with an unusually high density due to swarming.  However, due to the small size, their abundance is often underestimated.  In this paper, the diversity of planktonic ostracods in the mixed layer depth of the northeastern Arabian Sea in relation to environmental parameters during the summer monsoon is presented.  The mean abundance in the mixed layer depth was very high.  About 26 species belonging to 17 genera representing two families were recognized.  Out of this, 25 species belonged to (3 sub families, 16 genera the order Myodocopa and one to the order Myodocopida.  The dominant species were Cypridina dentata, Euconchoecia aculeata, Conchoecia subarcuata and Orthoconchoecia atlantica.  Cypridina dentata and Euconchoecia aculeata contributed to about 89% of the total abundance.  The results suggest that the distribution and diversity of ostracods were very much influenced by the hydrographic conditions of the Arabian Sea during the summer monsoon. 

  15. Complete mitochondrial genome DNA sequence for two ophiuroids and a holothuroid: the utility of protein gene sequence and gene maps in the analyses of deep deuterostome phylogeny.

    Scouras, Andrea; Beckenbach, Karen; Arndt, Allan; Smith, Michael J

    2004-04-01

    The complete mitochondrial genome sequences have been determined for the holothuroid Cucumaria miniata and two ophiuroid species Ophiopholis aculeata and Ophiura lütkeni. In addition, the nucleotide sequence of the mitochondrial protein-coding genes for the asteroid Pisaster ochraceus has been completed. Maximum-likelihood and LogDet distance analyses of concatenated protein-coding sequences produced a series of trees that did not conclusively support generally accepted models of echinoderm phylogeny. The ophiuroid data consistently demonstrated accelerated nucleotide divergence rates and lack of stationarity. This confounds the phylogenetic analyses. Molecular investigations using individual protein-coding gene alignments demonstrated that the cytochrome b gene exhibits the least deviation in rate and stationarity and generated some trees consistent with proposed echinoderm phylogenies. Phylogenies based on echinoderm mitochondrial gene rearrangements also proved problematic because of extensive variation in gene order between and within classes. A comparison of the two distinctive ophiuroid mitochondrial gene orders supports the hypothesis that O. lütkeni has a more derived mitochondrial gene order versus O. aculeata. The variation in the echinoderm mitochondrial gene maps reinforces the limitations of the application of mitochondrial gene rearrangements as a global phylogenetic tool. PMID:15019608

  17. performance of sorghum grown on a salt affected soil manured with dhaincha plant residues using a 15N isotopic dilution technique

    A field experiment was conducted on a salt-affected soil to determine the effect of application of three types of Dhaincha (Sesbania aculeata pers.) residues (R, roots; L, shoots; L+R, shoots plus roots) of on the performance of sorghum (Sorghum bicolor L.) using the indirect 15N isotopic dilution technique. Results indicated that Sesbania residues (L and L+R), used as green manures significantly increased grain yield, dry matter production, N uptake, and water use efficiency of sorghum. Percentages of N derived from residues (%Ndfr) in sorghum ranged from 6.4 to 28%. The N recoveries in sorghum were 52, 19. and 19.7% of the total amount contained in Sesbania roots, shoots and roots plus shoots, respectively. The beneficial effects of Sesbania residues are attributed not only to the additional N availability to the plants, but also to effects on the enhancement of soil N uptake, particularly in the L+R treatment. The findings suggest that the use of Sesbania aculeata residues, as a green manure, can provide a substantial portion of total N in sorghum. In addition, the use of Sesbania green manure in salt-affected soils, as a bio-reclaiming material, can be a promising approach for enhancing plant growth on a sustainable basis. (author)

  15. Las «tradiciones peruanas» y el imaginario de la nobleza titulada del virreinato

    Hampe Martínez, Teodoro

    2001-08-01

    Full Text Available In his Peruvian Traditions Ricardo Palma gave visible form to an image of the society, habits and most representative figures of the Peruvian history, focusing on the priviledged group integrated by the Viceroyalty's nobility. Mirroring the colonial heritage of the 19th Century, Palma represents an exceptional bridge towards the popular imaginario of the Ancient Regime. Although nonvoluntary errors or even distortions may have tainted his reconstruction of the facts, the «Traditions» put forward a mental universe which helps us to understand the experiences and human conditions of the past.

    Al plasmar en sus «tradiciones» una imagen de la sociedad, las costumbres y las figuras más representativas de la historia peruana, Ricardo Palma se fija en el grupo privilegiado de la nobleza titulada del Virreinato. Reflejando la herencia colonial del siglo XIX, Palma significa un puente excepcional hacia el imaginario popular del antiguo régimen. Aunque su reconstrucción de los hechos pueda estar viciada por errores involuntarios, o aun por tergiversaciones, las «tradiciones» expresan un universo mental que nos ayuda singularmente a comprender las experiencias y las condiciones humanas de ese pasado.
