The aim of this work was to determine the chemical composition of T. molitor grown in different artificial diets with bocaiuva pulp flour. The nutritional composition, fatty acid composition, antioxidant activity, trypsin activity and anti-nutritional factors of larvae were analyzed. The results showed that mealworms grown on artificial diet with bocaiuva are a good source of protein (44.83%) and lipid (40.45%), with significant levels of unsaturated fatty acids (65.99%), antioxidant activity (4.5 μM Trolox/g of oil extracted from larvae) and absence of anti-nutritional factors. This study indicates a new source of biomass for growing mealworms and shows that it is possible to breed mealworms in artificial diet with bocaiuva flour without compromising the nutritional quality of the larvae.

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

    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.

    Vegetable oils are important sources of essential fatty acids. It is, therefore, important to characterize plant species that can be used as new oil sources. This study aimed to characterize the oils from guariroba (Syagrus oleracea), jerivá (Syagrus romanzoffiana), and macaúba (Acrocomia aculeata). The physicochemical characterization was performed using official analytical methods for oils and fats, free fatty acids, peroxide value, refractive index, iodine value, saponification number, and unsaponifiable matter. The oxidative stability was determined using the Rancimat at 110 °C. The fatty acid composition was performed by gas chromatography. The results were submitted to Tukey's test for the medium to 5% using the ESTAT program. The pulp oils were more unsaturated than kernel oils, as evidenced by the higher refractive index and iodine value, especially the macaúba pulp oil which gave 1.4556 and 80 g I(2) /100 g, respectively, for these indices. The kernel oils were less altered by oxidative process and had high induction period, free fatty acids below 0.5%, and peroxide value around 0.19 meq/kg. The guariroba kernel oil showed the largest induction period, 91.82 h. Practical Application:  The vegetable oils, besides being consumed directly as food, are important raw material for the chemical, pharmaceutical, and food industries. In recent years, the world market of vegetable oils has been characterized by stronger growth of demand over supply. Several species of palm trees are shown to be promising sources of oils. The characterization of oils extracted from some species, such as guariroba, jerivá, and macaúba, has not yet been fully elucidated. For this reason, it becomes important to investigate the physicochemical characterization of these oils, aiming at a possible use in food or in the industry.

    Main conclusion Macauba palm fruiting is supra-annual, and the fruit growth follows a double sigmoidal trend. The prevailing compound in the mesocarp differs as the fruit ages, oil being the major storage compound. Acrocomia aculeata, macauba palm, is a conspicuous species in the tropical Americas. Because the species is highly productive in oil-rich fruits, it is the subject of domestication as an alternative vegetable oil crop, especially as a bioenergy feedstock. This detailed study first presents the macauba fruit growth and development patterns, morphological changes and accumulation of organic compounds. Fruits were monitored weekly in a natural population. The fruiting was supra-annual, and the fruit growth curve followed a double sigmoidal trend with four stages (S): SI-slow growth and negligible differentiation of the fruit inner parts; SII-first growth spurt and visible, but not complete, differentiation of the inner parts; SIII-growth slowed down and all structures attained differentiation; and SIV-second growth spurt and fruit maturation. In SII, the exocarp and endocarp were the main contributors to fruit growth, whereas the mesocarp and endosperm were responsible for most of the weight gain during SIV. In comparison with starch and oil, soluble sugars did not accumulate in the mesocarp. However, starch was transitory and fueled the oil synthesis. The protective layers, the exocarp and endocarp, fulfilling their ecological roles, were the first to reach maturity, followed by the storage tissues, the mesocarp, and endosperm. The amount and nature of organic compounds in the mesocarp varied with the fruit development and growth stages, and oil was the main and final storage material. The description of macauba fruit's transformations and their temporal order may be of importance for future ecological and agronomical references.

However, structural and physiological studies of the seed are still scarce, as well as in vitro propagation techniques. The aim of this study was to characterize the anatomy, histochemistry and ultrastructure of the seed and the in vitro somatic embryo of A. aculeata, gaining insight into relationships between the post-harvest seed behavior and the somatic embryo conversion to plant. The zygotic embryo and the endosperm show high quantities of protein and lipids, stored in protein and lipid bodies, respectively. The cell wall storage polysaccharides occur in the thickened cell wall of the endosperm. The absence of vacuoles and the few organelles, except for the storage ones, indicate low metabolic state of the zygotic embryo, which suggests a orthodox behavior of the seed at maturity. The somatic embryo shows a shoot meristem with few leaf primordia, vacuolated cells and, occasionally, amyloplasts , but not lipid or protein reserves. These characteristics, common in somatic embryogenesis, could be associated with the maturation phase, and, consequently, with the low conversion of these embryos into plants.A macaúba (Acrocomia aculeata (Jacq.

    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

    The aims of this work were to study the chemical composition of the essential oil from the leaves of Pereskia aculeata and to evaluate some biological activities of three leaf extracts. The phenolic content, antioxidant activity, and in vitro antimicrobial and antifungal activities were determined. The methanol extract showed antioxidant activity (EC50 7.09 mg/mL) and high polyphenols content (15.04 ± 0.31 mg gallic acid equivalents (GAE)/g). The petroleum ether extract exhibited potent antibacterial activity against Escherichia coli, whereas the chloroform extract showed inhibitory activity against Bacillus cereus and Staphylococcus aureus. The petroleum ether and methanol extracts were more effective in inhibiting the growth of Aspergillus versicolor. The possible cytotoxicity of extracts on neuroblastoma SH-SY5Y cancer cell line and the influence on adenylate cyclase (ADCY) expression was also studied. P. aculeata chloroform extract showed antiproliferative activity with an IC50 value of 262.83 µg/mL. Treatments of SH-SY5Y neuroblastoma cells with 100 µg/mL of methanol extract significantly reduced ADCY1 expression. PMID:27598154

    Full Text Available The Parkinsonia aculeata L seeds have tegumentary dormancy, which makes them last for a long period in the seed bank of the earth so that their germination occurs in favorable conditions. Our aim was to evaluate the influence of pregermination treatments for overcoming the dormancy of P. aculeata seeds. The seeds were submitted to the following treatments: sample – intact seeds (T1; mechanical scarification with water sandpaper no. 80, followed by room temperature water soaking for 12 and 24 hours (T3 e T4, respectively; immersion in sulfuric acid for 5, 10, 15 and 20 minutes (T5, T6, T7 e T8, respectively; immersion in water in 60ºC, 70ºC, 80ºC and 90ºC for one minute (T9, T10, T11 e T12, respectively. 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.

    The brightness of the moonless night sky above La Palma was measured on 427 CCD images taken with the Isaac Newton and Jacobus Kapteyn Telescopes on 63 nights during 1987 - 1996. The median sky brightness at high elevation, high galactic latitude and high ecliptic latitude, at sunspot minimum, is B = 22.7, V = 21.9, R = 21.0, similar to that at other dark sites. The main contributions to sky brightness are airglow and zodiacal light. The sky is brighter at low ecliptic latitude (by 0.4 mag); at solar maximum (by 0.4 mag); and at high airmass (0.25 mag brighter at airmass 1.5). Light pollution (line + continuum) contributes < 0.03 mag in U, approximately 0.02 mag in B, approximately 0.10 mag in V, approximately and 0.10 mag in R at the zenith.

    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.

    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).

    Premise of the study: Polymorphic microsatellite markers were developed for the lichen species Cetraria aculeata (Parmeliaceae) to study fine-scale population diversity and phylogeographic structure. Methods and Results: Using Illumina HiSeq and MiSeq, 15 fungus-specific microsatellite markers were developed and tested on 81 specimens from four populations from Spain. The number of alleles ranged from four to 13 alleles per locus with a mean of 7.9, and average gene diversities varied from 0.40 to 0.73 over four populations. The amplification rates of 10 markers (CA01–CA10) in populations of C. aculeata exceeded 85%. The markers also amplified across a range of closely related species, except for locus CA05, which did not amplify in C. australiensis and C. “panamericana,” and locus CA10 which did not amplify in C. australiensis. Conclusions: The identified microsatellite markers will be used to study the genetic diversity and phylogeographic structure in populations of C. aculeata in western Eurasia. PMID:27672520

  1. 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...

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.

    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.

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

    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

    Full Text Available Capoeta aculeata is a benthopelagic fresh-water fish that lives in subtropical climates and has awidely distribution in Iranian river basins. Hatchery production of fish for stocking is an important means oftemporarily supplementing insufficient natural reproduction, thus help to maintain or restore eroded fishpopulation. This study was done in May and June 2007 on captured brood fish from Zayandeh-Rood River,Iran in order to reach a suitable technique of artificial reproduction of C. aculeata. Caught brood fish wereinjected with carp pituitary extract at doses of 0.75 and 1.5 milligram per kilogram body weight of fish.Brood fish were tested for ovulation each 12 hours from final injection for 3 days, but no sing of readinessfor spawning was observed. To gain confidence of experiment, the study was repeated after one monthfrom the first try with new fish. The result, however, was the same and didn’t attain to any success.Inadequate information about reproduction biology of this species is one of the most important reasons ofthe negative result. Furthermore, unsuitable hormone and dosages as well as inappropriate injection timescan be probable causes of this failure that should be evaluated in later studies.

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

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

    In 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.

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

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

    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.

  17. SAGE CALCULATIONS OF THE TSUNAMI THREAT FROM LA PALMA

    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.

    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

    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.

    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

    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.

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

    International Nuclear Information System (INIS)

    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)

    The Liverpool telescope on La Palma will provide live images for planetarium shows in the Liverpool Museum in the UK. Data transfer will be achieved using the Internet. We implemented an automatic program of hourly ftp file transfers from La Palma to the UK throughout 1998 and 1999 to monitor the transfer rates achievable. We find that both the mean and minimum (on 9 out of 10 nights) transfer rates are a function of time of day on weekdays. In addition we find that the minimum transfer rate in early evening has increased from approximately 5 Kbytes/sec in 1998 to approximately 25 Kbytes/sec in 1999. This implies that a compression ratio of around 30:1 must be achieved to allow live display of 2048 X 2048 pixel CCD images in the UK within 10 seconds of the data being taken.

  10. 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.

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

    Directory of Open Access Journals (Sweden)

    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.

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

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

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

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

    Directory of Open Access Journals (Sweden)

    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.

    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).

    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

    Coastal transport in the Bay of Palma, a small region in the island of Mallorca, Spain, is characterized in terms of Lagrangian descriptors. The data sets used for this study are the output for two months of a high resolution realistic numerical model, ROMS, forced atmospherically and with a spatial resolution of 300 m. Semi-persistent Lagrangian coherent structures (LCS) are found during both months. We study the fluid interchange between the Bay and the open ocean by computing particle trajectories and residence times. We found clear differences between autumn and summer. Stirring is smaller in autumn (October) than in summer (July), presenting diurnal variability at both months, probably induced by the effect of the wind. The escape rate of particles out of the Bay is qualitatively different, with more particles escaping to the ocean in October than in July. We show that LCSs separate regions with different transport properties, and display spatial distributions of residence times on synoptic Lagrangian ma...

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

    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.

    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.

    2001-12-01

    Full Text Available The work of Gonzalo de Berceo, a native of the Rioja región of Spain who lived in the 12th and 13th centuries, illustrates the reutilization of the classic symbols of the crown and the palm as heavenly awards in the afterlife. The author analyzes Berceo's texts on the rituals of coronation and triumph as well as his sources, most of which were the canonical and the apocryphal Gospels. The author brings iconography to bear on this analysis: the iconography before and during Berceo's time as well as that which has been produced since, possibly because of the religious endurance of the oral and written tradition.

    La reutilización de los símbolos clásicos de la corona y la palma como premios celestiales en la vita post mortem se estudia aquí a través de la obra del riojano Gonzalo de Berceo, que vivió a caballo entre los siglos XII y XIII. El análisis textual sobre los ceremoniales de coronación y de triunfo, así como de las fuentes, en gran parte evangélicas (canónicas y apócrifas, de las que bebe este autor, se completa con ejemplos de la iconografía precedente, coetánea y también la que se ha generado hasta hoy, quizá por la pervivencia religiosa de la tradición oral y escrita.

    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.

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

    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.

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

    Science.gov (United States)

    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

    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

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

    Directory of Open Access Journals (Sweden)

    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 En este trabajo se presentan las principales pautas del comportamiento térmico de la ciudad de Las Palmas de Gran Canaria. 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.

    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.

    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.

    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...

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

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

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.

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

    International Nuclear Information System (INIS)

    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

    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.

    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.

    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.

    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

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 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.

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.

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

    International Nuclear Information System (INIS)

    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.

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

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

    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

    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.

    International Nuclear Information System (INIS)

    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.

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

    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 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.

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.

    Full Text Available La agricultura de precisión está basada en el reconocimiento de la variabilidad espacial y temporal del clima, los suelos y los cultivos, y consecuentemente, de la importancia de proporcionar un manejo agronómico específico que tenga en cuenta esas diferencias. En este artículo se describe la perspectiva y los conceptos de agricultura de precisión que se están desarrollando en el sector de la palma de aceite en Colombia. En particular, se presentan dos aplicaciones que resuelven las limitaciones asociadas a las prácticas agrícolas convencionales: una, relacionada con el trazado de una plantación; y otra referida al manejo de plagas y enfermedades./ Precision agriculture is based on the recognition of the spatial and temporal variability of weather, soils and crops. Thus, its importance lies in providing a specific agricultural management that takes into account these differences. This article describes the vision and concepts developed for precision farming of oil palm in Colombia. In particular, there are two applications that address the limitations associated with conventional farming practices: one is connected to plantation layouts, and the other to pest and disease management.

    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.

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

Suas margens apresentam um elevado potencial recreacional, portanto, as condições sanitárias necessárias às atividades de contato primário devem ser asseguradas à população. Indicadores de balneabilidade devem ser avaliados em ambientes com fins recreacionais com o objetivo de prever e evitar efeitos adversos à saúde humana e à biota aquática. O presente trabalho realizou a avaliação do parâmetro indicador de contaminação fecal, Escherichia coli, para a classificação da balneabilidade em quatro praias na capital do Estado do Tocantins, Palmas. São elas as Praias do: Caju, Prata, Graciosa e das Arnos. Para tal, foram realizadas a detecção e contagens de Escherichia coli pela técnica do substrato cromogênico, de amostras coletas em cinco semanas, entre os anos de 2012 e 2015. As águas apresentaram baixas contagens de Escherichia coli, que permitiram a classificação como muito boa ou excelente balneabilidade, conforme a Resolução CONAMA Nº 274/2000. Dessa forma, o trabalho contribui para assegurar as atividades de lazer com segurança, e construir um banco de dados importante sobre as condições microbiológicas das praias pertencentes ao reservatório.

    Full Text Available La pudrición del cogollo (PC es la principal enfermedad de la palma en Colombia. En las zonas palmeras Central (ZC y Oriental (ZOR, las palmas enfermas pueden recuperarse naturalmente. En la Zona Occidental (ZOCC el proceso de recuperación no es evidente. La recuperación de palmas está ligada a gran actividad meristemática que podría involucrar la acción de metabolitos como las poliaminas (PA. Este trabajo muestra la relación entre el contenido de poliaminas en el meristemo y la capacidad de recuperación de palmas con PC, en dos zonas agroclimáticas diferentes. Poliaminas extraídas del meristemo de palmas en ZC y ZOCC, fueron analizadas por HPLC. En ZC, donde existe recuperación espontánea, los niveles más altos de PA se presentan en palmas sanas y en recuperación y a medida que avanza la enfermedad la concentración desciende hasta un mínimo en el estado de PC inicial. 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.

    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

Este artículo presenta una comparación entre imágenes que contienen la región de interés de la palma de la mano, obtenidas mediante el uso de técnicas de umbralización, Otsu y Huang para la base de datos PolyU y Otsu e Isodata para la base de datos CASIA. También se realizaron pruebas con dos métodos para la ubicación del cuadrado correspondiente a la ROI, utilizando como medidas de similitud: la correlación, la información mutua, el error cuadrático medio, la relación de uniformidad de la imagen y el área común entre las imágenes, Todo esto, para determinar qué tan similares o diferentes son las imágenes generadas por diferentes métodos de ubicación de ROI y por distintos métodos de umbralización. Esta investigación demostró que efectivamente el cambio de los métodos de umbralización generan cambios en la ROI de la palma de la mano ya que la localización de los puntos valle cambia según el método utilizado. Se concluye finalmente que al variar el método de umbralización, las imágenes generadas por cada método son diferentes y al variar el método de obtención de la ROI la variación es mayor.

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

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

    Full Text Available No processamento tradicional de extração de óleo de palma, uma quantidade substancial do produto é perdida na fibra - durante a etapa de prensagem do fruto - e na borra - durante a etapa de clarificação do óleo cru. A viscosidade deste constitui a principal dificuldade de separação do óleo dos demais componentes da mistura. A eficiência de recuperação do óleo é usualmente melhorada por adição de água, no tanque de clarificação. Neste trabalho avaliou-se os efeitos da diluição e do tratamento enzimático no comportamento reológico do óleo de palma cru. Estes dados são importantes para estimar a velocidade de separação do óleo nos tanques de clarificação e/ou nos decanters das usinas comerciais. O óleo cru utilizado neste estudo foi recolhido em uma unidade comercial sendo composto de 65% de água, 30% de óleo e 5% de sólidos. A hidrólise enzimática foi conduzida usando como agentes hidrolisantes uma enzima comercial (viscozyme da Novo Nordisk e um preparado enzimático produzido no CTAA. Pode-se constatar que quanto mais diluída a amostra maior é a redução na viscosidade após a hidrólise enzimática. Para uma taxa de deformação fixa em 6s-1, o tratamento enzimático do óleo cru a 60°C reduziu a viscosidade do mesmo em cerca de 29% enquanto a adição de 20% de água em cerca de 35%. A combinação da diluição com 20% de água seguida de tratamento enzimático reduziu a viscosidade do óleo cru em cerca de 75%.In conventional extraction of palm oil, a substantial loss of product occurs in the stages of the fruit pressing and clarification of the "crude" oil. The high viscosity of "crude" oil is the main factor that affects the separation of the oil from the other components in the mixture. This is usually overcome by the addition of water in the clarification stage. This work addresses the study of the influence of dilution and enzymatic treatments on the rheological behaviour of crude oil. Data

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

    Full Text Available 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.

El cual incluyó la zonificación ecológica del territorio, laidentificación de los diferentes grados de intervención del bosque, la recopilación de la historiade uso de la palma, la caracterización del sistema de aprovechamiento para la elaboración dela artesanía; y el análisis de la forma como estos parámetros inciden en la distribución y abun-dancia de la especie. Teniendo en cuenta esta información se seleccionaron dos sitios demuestreo, en cada uno de los cuales se identificaron las condiciones ambientales que favorecenel crecimiento de la palma y su producción de fibra. Para esto se demarcaron las parcelasen las que se llevó a cabo el conteo de los individuos, la evaluación de su rendimiento pormedio del análisis de biomasa y del índice AFE; y la evaluación de las condiciones físicas,químicas y biológicas del suelo que lo afectan. Como resultado del análisis se propone la im-plantación de un programa de propagación y aprovechamiento, que tenga en cuenta la distri-bución de los ecosistemas y los grados de intervención del bosque que favorecen el crecimientode la palma. Y se proponen técnicas de manejo de las condiciones ambientales y de los aspectosde la relación planta - suelo que favorecen el mayor rendimiento en la producción de fibra;haciendo énfasis en el manejo de la asociación micorrícica observada.

    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.

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

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

    Full Text Available 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.

    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

    The hormonal mechanisms involved in palm seed germination are not fully understood. To better understand how germination is regulated in Arecaceae, we used macaw palm (Acrocomia aculeata (Jacq.) Lodd. Ex Mart.) seed as a model. Endogenous hormone concentrations, tocopherol and tocotrienol and lipid peroxidation during germination were studied separately in the embryo and endosperm. Evaluations were performed in dry (D), imbibed (I), germinated (G) and non-germinated (NG) seeds treated (+GA3 ) or not treated (control) with gibberellins (GA). With GA3 treatment, seeds germinated faster and to a higher percentage than control seeds. The +GA3 treatment increased total bioactive GA in the embryo during germination relative to the control. Abscisic acid (ABA) concentrations decreased gradually from D to G in both tissues. Embryos of G seeds had a lower ABA content than NG seeds in both treatments. The GA/ABA ratio in the embryo was significantly higher in G than NG seeds. The +GA3 treatment did not significantly affect the GA/ABA ratio in either treatment. Cytokinin content increased from dry to germinated seeds. Jasmonic acid (JA) increased and 1-aminocyclopropane-1-carboylic acid (ACC) decreased after imbibition. In addition, α-tocopherol and α-tocotrienol decreased, while lipid peroxidation increased in the embryo during germination. We conclude that germination in macaw palm seed involves reductions in ABA content and, consequently, increased GA/ABA in the embryo. Furthermore, the imbibition process generates oxidative stress (as observed by changes in vitamin E and MDA).

    The use of leaves of Prunifera Copernicia (Arecaceae as exclusive food of bovines was associated by the death of 40 of the 146 animals during a period of 2 months of consumption. The leaves of this plant had been supplied experimentally for two goats that died with 31 and 56 days the beginning of the ingestion. Clinical manifestations consisted in increased feces consistence, weakness, recumbence and death. The main pathological findings had been epithelial tubular degeneration and necrosis in the kidneys and hepatic centrolobular coagulative necrosis associated with congestion and hemorrhage. This work relates the mortality of bovines to the leaf consumption of Copernicia prunifera and characterizes it the experimental poisoning for this plant in goat.

    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.

    Abstract Monts de Cristal National Park in northwest Gabon is one of the most species rich places in Central Africa. Here, we describe two new species, one in Annonaceae and one in palms. Uvariopsis citrata Couvreur & Niangadouma, sp. nov. is unique in the genus by emitting a strong lemon scent from the crushed leaves and young branches. Laccosperma cristalensis Couvreur & Niangadouma, sp. nov. is a rattan that lacks acanthophylls on the cirrus and has few pinnae. Complete descriptions, photographic illustrations, ecological information and preliminary IUCN conservation status are provided. For both species a data deficient (DD) status is proposed. These new species underline once again that the Monts de Cristal National Park is yet incompletely known botanically. PMID:27698570

    Stereo-SCIDAR is a generalised-SCIDAR instrument which is used to characterise the atmospheric optical turbu- lence in terms of strength (Cn2) and wind velocity profile using the triangulation technique and an optical binary star. Stereo-SCIDAR differs from most other SCIDAR instruments in that, instead of overlapping pupil images on a single detector, the image of each star is recorded on a separate EMCCD. Separating the pupil images in this way leads to several advantages, including better ...

    Palms are ubiquitous across Neotropical landscapes, from pristine forests or savannahs to large cities. Although palms provide useful ecosystem services, they also offer suitable habitat for triatomines and for Trypanosoma cruzi mammalian hosts. Wild triatomines often invade houses by flying from nearby palms, potentially leading to new cases of human Chagas disease. Understanding and predicting triatomine-palm associations and palm infestation probabilities is important for enhancing Chagas disease prevention in areas where palm-associated vectors transmit T. cruzi. We present a comprehensive overview of palm infestation by triatomines in the Americas, combining a thorough reanalysis of our published and unpublished records with an in-depth review of the literature. We use site-occupancy modeling (SOM) to examine infestation in 3590 palms sampled with non-destructive methods, and standard statistics to describe and compare infestation in 2940 palms sampled by felling-and-dissection. Thirty-eight palm species (18 genera) have been reported to be infested by ∼39 triatomine species (10 genera) from the USA to Argentina. Overall infestation varied from 49.1-55.3% (SOM) to 62.6-66.1% (dissection), with important heterogeneities among sub-regions and particularly among palm species. Large palms with complex crowns (e.g., Attalea butyracea, Acrocomia aculeata) and some medium-crowned palms (e.g., Copernicia, Butia) are often infested; in slender, small-crowned palms (e.g., Euterpe) triatomines associate with vertebrate nests. Palm infestation tends to be higher in rural settings, but urban palms can also be infested. Most Rhodnius species are probably true palm specialists, whereas Psammolestes, Eratyrus, Cavernicola, Panstrongylus, Triatoma, Alberprosenia, and some Bolboderini seem to use palms opportunistically. Palms provide extensive habitat for enzootic T. cruzi cycles and a critical link between wild cycles and transmission to humans. Unless effective means to

    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.

    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.

PUN levels in plasma did not change. The apparent digestibility of DM, OM, NDF, ADF, NFC, EE and TDN decreased linearly, and CP increased (P <0.05. Weight gains decreased since the FC increased (P <0.05. No effect was observed in nitrogen intake and nitrogen excreted in the urine. A reduction in nitrogen excreted in the faeces nitrogen bal-ance and percentage of ingested nitrogen, urea-N excreted in the urine increased (P <0.05. The replacement of corn by palm reduces the performance of dairy females in pasture growth. Thus the total or partial replacement is conditioned to the projection of age at first calving on the production system and economy of use.

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

    The 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.

    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.

Conclusiones. Un bajo nivel socioeconómico se asocia a un mayor riesgo de que los adolescentes españoles fumen, beban alcohol, suspendan, vean más televisión y no practiquen deporte. Además, el que la madre beba se asocia a un mayor riesgo de que sus hijos fumen y beban, y el que ambos padres beban se asocia a un mayor riesgo de que sus hijos lo hagan. La práctica de deportes y el tiempo que pasan ante el televisor los padres influyen en los hábitos correspondientes por parte de sus hijos, pero no influyen en que el adolescente beba o fume.

    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.

    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.

    Full Text Available This hall is the first stage of an ambitious programme of reforms and extensions to the Metropole Swimming Club which, apart from increasing and diversifying the number of the sports installations, includes others of an eminently social nature. The numerous conditioning factors which limited the construction of the hall from the beginning, both regarding the surface —rectangular and extremely elongated, messuring 13 x 13 m, and height— about 3 m, and regarding its situation within the whole, lead to the arrangement of three articulated atmospheres within a single space, covered with thin reinforced concrete warped membranes, as the only solution capable, on the one hand, of reducing the coldness and stiffness of the structure imposed, and on the other, of satisfactorily answering the design bases which prefixed multifunctionality, transparency and representativity of the building. A final premiss which called for the integration of the work in a surrounding gardaned environment was solved by the complete glazing of the frontages and the light tones of the finishing materials.

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

    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.

    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 calcu

    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.

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

    The increasing related ambient concerns to the emissions of atmospheric pollutants for fuels, alternative sources of energy are having bigger attention, mainly those that contribute in the mitigation of these emissions. Being thus, the use of the biodiesel produced by the etherification of vegetal oils with methanol and ethanol, are seen as present interesting alternative. The energy analysis of the relation of the energy invested in the production of bio diesel can contribute as tool for a posterior formularization of pointers of the technician-economic and ambient viability in the comparison between the different oleaginous, as form to diagnosis one better type of culture for the production of biodiesel. The objectives of this work is to carry the energy analysis in the production of the palm oil biodiesel, for the conditions of Brazil and Colombia, as well as showing the differences between the results found for the two cases. The presented results are shown through comparative graphs for the two cases and with the final energy balance for each company. (author)

    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 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).

    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

  9. Canopy-forming seaweeds in urchin-dominated systems in eastern Canada: structuring forces or simple prey for keystone grazers?

    Directory of Open Access Journals (Sweden)

    Caitlin Blain

    Full Text Available Models of benthic community dynamics for the extensively studied, shallow rocky ecosystems in eastern Canada emphasize kelp-urchin interactions. These models may bias the perception of factors and processes that structure communities, for they largely overlook the possible contribution of other seaweeds to ecosystem resilience. We examined the persistence of the annual, acidic (H2SO4, brown seaweed Desmarestia viridis in urchin barrens at two sites in Newfoundland (Canada throughout an entire growth season (February to October. We also compared changes in epifaunal assemblages in D. viridis and other conspicuous canopy-forming seaweeds, the non-acidic conspecific Desmarestia aculeata and kelp Agarum clathratum. We show that D. viridis can form large canopies within the 2-to-8 m depth range that represent a transient community state termed "Desmarestia bed". The annual resurgence of Desmarestia beds and continuous occurrence of D. aculeata and A. clathratum, create biological structure for major recruitment pulses in invertebrate and fish assemblages (e.g. from quasi-absent gastropods to >150,000 recruits kg(-1 D. viridis. Many of these pulses phase with temperature-driven mass release of acid to the environment and die-off in D. viridis. We demonstrate experimentally that the chemical makeup of D. viridis and A. clathratum helps retard urchin grazing compared to D. aculeata and the highly consumed kelp Alaria esculenta. In light of our findings and related studies, we propose fundamental changes to the study of community shifts in shallow, rocky ecosystems in eastern Canada. In particular, we advocate the need to regard certain canopy-forming seaweeds as structuring forces interfering with top-down processes, rather than simple prey for keystone grazers. We also propose a novel, empirical model of ecological interactions for D. viridis. Overall, our study underscores the importance of studying organisms together with cross-scale environmental

    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.

    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.

    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.

    A survey was designed to know the concentration of Naegleria fowleri in recreational areas in Hornos, Sonora, during a year. Samples were taken monthly at La Isleta and Las Palmas and the total amoeba counts were obtained by the most probable number method (MPN). The identification of N. fowleri was made by PCR. The maximum concentration of total thermophilic amoebae was 9175 MPN/L for La Isleta and 3477 MPN/L for Las Palmas. Thermophilic Naegleria were present mainly during summer and fall. October's concentrations were up to 201 MPN/L, at both places. The maximum concentrations of N. fowleri were 201 MPN/L and 18 MPN/L for La Isleta and Las Palmas respectively, and were isolated from August to October. The presence of N. fowleri in these particular natural bodies of water reinforces the need for adaptation of preventive measures to avoid cases of primary amoebic meningoencephalitis.

    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. 

  7. 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.

    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

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

    International Nuclear Information System (INIS)

    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)

    2012-06-12

    In several Hymenoptera, sexual fate is determined by the allelic composition at the complementary sex-determiner locus, a sex-determination mechanism that can strongly affect population dynamics. To date, the molecular identification of complementary sex determiner has only been achieved in the honeybee, where the complementary sex-determiner gene was reported to have arisen from duplication of the feminizer gene. Strikingly, the complementary sex-determiner gene was also proposed to be unique to the honeybee lineage. Here we identify feminizer and complementary sex-determiner orthologues in bumble bees and ants. We further demonstrate that the duplication of feminizer that produced complementary sex determiner occurred before the divergence of Aculeata species (~120 Myr ago). Finally, we provide evidence that the two genes evolved concertedly through gene conversion, complementary sex-determiner evolution being additionally shaped by mosaic patterns of selection. Thus, the complementary sex-determiner gene likely represents the molecular basis for single locus-complementary sex determination in the Aculeata infra-order, and possibly, in the entire Hymenoptera order.

    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.

  6. Production of ethanol from lepthochloa fusca L. (kallar grass) and panicum maximum using cellulases from trichoderma SSP and cultures of saccharomyces carlsbergensis

    International Nuclear Information System (INIS)

    Saline sodic soils have been used for production of biomass using salt tolerant grass, kallar grass followed by lesser tolerant plants, namely, sasbania aculeata or Panicum maximum or to provide biomass throughout the year for it utilization for microbial conversion. These substrates have been utilized to produce single cell protein and cellases or hemicellulases. The enzyme titer obtained after growth of cellulomonas biazotea on kallar grass could saccharify wheat straw ad bagasse for subsequent conversion to ethanol but kallar grass itself was saccharified to lesser extent, however, enzyme titres from different fungi could saccherify the biomass produced on saline lands to monomeric sugars. In these studies, the enzyme titre from Trichoderma spp. were used for saccharification purpose. (author)

    Diabetes mellitus is a syndrome which affects more and more people in all countries over the world. In México, it is commonly treated with herbal extracts. Such treatment may be of considerable benefit especially during the early stages of the illness. In this review, we discuss species commonly used in México in the treatment of diabetes. A total of 306 species have records of a popular use in the treatment of this syndrome in México. Seven of these species--Cecropia obtusifolia Bertol. (Cecropiaceae), Equisetum myriochaetum Schlecht & Cham (Equisetaceae), Acosmium panamense (Benth.) Yacolev (Fabaceae), Cucurbita ficifolia Bouché (Cucurbitaceae), Agarista mexicana (Hemsl.) Judd. (Ericaeae), Brickellia veronicaefolia (Kunth) A. Gray (Asteraceae), Parmentiera aculeata (Kunth) Seem. (Bignoniaceae)--are discussed in greater detail, highlighting our current knowledge about these botanicals, but also the enormous gaps in our knowledge, most notably as it relates to the species' toxicology, the pharmacokinetics of its active constituents and their metabolism.

  8. Comparison on trace elements in squid statoliths of different species' origin: as available key for taxonomic and phylogenetic study

    International Nuclear Information System (INIS)

    Trace elements in squid statoliths were analyzed by PIXE for the following fourteen species in five families of different habit origin: Ommastrephidae, Ommastrephes bartrami, Dosidicus gigas, Sthenoteuthis oualaniensis; Gonatidae, Gonatopsis makko, G. borealis, Berryteuthis magister; Loliginidae, Loligo bleekeri, L. duvaucelii, L. chinensis, L. edulis and Sepioteuthis lessoniana; Sepiidae, Sepia aculeata and Sepiella inermis; Sepiolidae, Rossia pacifica. Manganese, iron, copper, zinc and strontium were detected from statoliths of all species examined. Among these trace elements, Sr is the highest in concentration. Variation of statoliths Sr concentration reflects taxonomic position and the habitat of specimens. In Ommastrephids and Gonatids, that have oceanic habitat, statoliths Sr concentration is relatively high whereas that of Loliginids and Sepiids, that have coastal habitat, is comparatively low. This fact supports our previous report on this subject. R pacifica exceptionally shows high statoliths Sr concentration although this species inhabits in coastal water. (author)

    2010-01-01

    Full Text Available Benthic foraminifera were cultured for five months at four temperatures (4, 7, 14 and 21 °C to establish the temperature dependence of foraminiferal δ18O and Mg/Ca. Two Bulimina species (B. aculeata and B. marginata were most successful, adding chambers at all four temperatures and reproducing at 7 and 14 °C. Foraminiferal δ18O values displayed ontogenetic variations, with lower values in younger individuals. The δ18O values of adult specimens decreased with increasing temperature in all but the 4 °C treatment, exhibiting a relationship consistent with previous δ18O paleotemperature calibration studies. Foraminiferal Mg/Ca values, determined by laser ablation inductively coupled plasma mass spectrometry, were broadly consistent with previous Mg/Ca calibration studies, but extremely high values in the 4 °C treatment and higher than expected values at two of the other three temperatures make it challenging to interpret these results.

    In this study, pulp and kernel of fruits from six Arecaceae species were subjected to proximate analysis, fatty acid composition and total carotenoid content analysis. The species with the highest carbohydrate, lipid and protein values were Ptychosperma macarthurii(70.1 g/100 g in the kernel), Syagrus cearensis(40.6 g/100 g in the kernel), andS. coronata(20.6 g/100 g in the pulp). The ash content ranged from 0.61 to 7.51 g/100 g. Lauric, palmitic, and oleic acids were the major fatty acids identified. The total carotenoid contents and retinol activity equivalents were highest in the Pinanga kuhlii (180.3 µg/g) and Acrocomia intumescens (138.0 µg/g) pulp oils. Retinol activity equivalents varied between the investigated species (456 to 1515 μg RAE/100 g). Native species such as A. intumescens, S. coronata, and S. cearensis are good sources of fresh food for the underserved populations that inhabit poorly developed areas such as the semi-arid region of Brazil. P. macarthurii, an exotic species, is an excellent source of ash and carotenoids, demonstrating its potential both as a food source and as bioactive compounds. Pulp and kernel ofA. intumescens,could be a good alternative feedstock for soap and biodiesel production, respectively. PMID:26221983

    Full Text Available Abstract Background Ethnomedicines are used by hunters for themselves and their hunting dogs in Trinidad. Plants are used for snakebites, scorpion stings, for injuries and mange of dogs and to facilitate hunting success. Results Plants used include Piper hispidum, Pithecelobium unguis-cati, Bauhinia excisa, Bauhinia cumanensis, Cecropia peltata, Aframomum melegueta, Aristolochia rugosa, Aristolochia trilobata, Jatropha curcas, Jatropha gossypifolia, Nicotiana tabacum, Vernonia scorpioides, Petiveria alliacea, Renealmia alpinia, Justicia secunda, Phyllanthus urinaria,Phyllanthus niruri,Momordica charantia, Xiphidium caeruleum, Ottonia ovata, Lepianthes peltata, Capsicum frutescens, Costus scaber, Dendropanax arboreus, Siparuma guianensis, Syngonium podophyllum, Monstera dubia, Solanum species, Eclipta prostrata, Spiranthes acaulis, Croton gossypifolius, Barleria lupulina, Cola nitida, Acrocomia ierensis (tentative ID. Conclusion Plant use is based on odour, and plant morphological characteristics and is embedded in a complex cultural context based on indigenous Amerindian beliefs. It is suggested that the medicinal plants exerted a physiological action on the hunter or his dog. Some of the plants mentioned contain chemicals that may explain the ethnomedicinal and ethnoveterinary use. For instance some of the plants influence the immune system or are effective against internal and external parasites. Plant baths may contribute to the health and well being of the hunting dogs.

  15. Isolation and structural elucidation of secondary metabolites from plants of the family Flacourtiaceae and Asclepiadaceae, and evaluation of biological activity of the sesquiterpene lactones and the diterpenes of Casearia sp

    International Nuclear Information System (INIS)

    A phytochemical study was realized of the plants Casearia aculeata, Casearia nitida and Asclepias verticillata, using experiments of nuclear magnetic resonance (NMR) of one and two dimensions. Ten secondary metabolites are isolated from C. aculeata and C. nitida. Three of the secondary metabolites have presented a structure known: a diterpene type kaurane: ent-kaurenic acid, a diterpene type pimarane: oxide of 3β-hydroximanoil and a steroid: 4-stigmastene-3-ona. Seven remaining compounds have corresponded to diterpene type clerodane of novel structure. Eight glycosides of poly oxidized pregnanes of novel structure are isolated from A. verticillata. In vitro tests of cytotoxicity and induction of caspase-3 are performed on leukemia cells type Jurkat T. These tests were performed at fifteen sesquiterpene lactones and at four diterpenes. The tests developed have had the purpose to describe structure-activity relationships that can be linked with the capacity to inhibit the factor NF-κB (sesquiterpene lactones) described in the literature and with the known mechanism of action induction of apoptosis in diterpenes type clerodane. A clear relationship between the capacity (high, intermediate or low) to inhibit the factor NF-κB and the capacity to induce to the caspase-3 has remained without observation in the sesquiterpene lactones. Some structural comparisons related with the cytotoxic capacity and the induction of the caspase-3 have been described for the series of LSs with carbon structure of pseudoguianolides. Diterpenes with carbon structure of diterpenes type clerodane have had greater cytotoxic activity with respect to without carbon structure. Diterpenes type clerodane isolated from the family Flacourtiaceae have been cytotoxics, their capacity to induce to the caspase-3 has remained without be nearby to induction realized by the actinomycin D (pure inducer of the caspase-3).

    The First Geiger-mode Avalanche photodiode (G-APD) Cherenkov Telescope (FACT) has been operating on the Canary island of La Palma since October 2011. Operations were automated so that the system can be operated remotely. Manual interaction is required only when the observation schedule is modified due to weather conditions or in case of unexpected events such as a mechanical failure. Automatic operations enabled high data taking efficiency, which resulted in up to two terabytes of FITS files being recorded nightly and transferred from La Palma to the FACT archive at ISDC in Switzerland. Since long term storage of hundreds of terabytes of observations data is costly, data compression is mandatory. This paper discusses the design choices that were made to increase the compression ratio and speed of writing of the data with respect to existing compression algorithms. Following a more detailed motivation, the FACT compression algorithm along with the associated I/O layer is discussed. Eventually, the performances...

  18. HERMES at Mercator, competitive high-resolution spectroscopy with a small telescope

    Science.gov (United States)

    Raskin , G.; Van Winckel, H.

    2014-01-01

    HERMES, a fibre-fed high-resolution (R = 85 000) échelle spectrograph with good stability and excellent throughput, is the work-horse instrument of the 1.2-m Mercator telescope on La Palma. HERMES targets building up time series of high-quality data of variable stellar phenomena, mainly for asteroseismology and binary-evolution research. In this paper we present the HERMES project and discuss the instrument design, performance, and a future upgrade. We also present some results of the first four years of HERMES observations. We illustrate the value of small telescopes, equipped with efficient instrumentation, for high-resolution spectroscopy. Based on observations made with the Mercator Telescope, operated on the island of La Palma by the Flemish Community, at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias.

    2014-01-01

    The robotic 2m Liverpool Telescope, based on the Canary island of La Palma, has a diverse instrument suite and a strong track record in time domain science, with highlights including early time photometry and spectra of supernovae, measurements of the polarization of gamma-ray burst afterglows, and high cadence light curves of transiting extrasolar planets. In the next decade the time domain will become an increasingly prominent part of the astronomical agenda with new facilities such as LSST, SKA, CTA and Gaia, and promised detections of astrophysical gravitational wave and neutrino sources opening new windows on the transient universe. To capitalise on this exciting new era we intend to build Liverpool Telescope 2: a new robotic facility on La Palma dedicated to time domain science. The next generation of survey facilities will discover large numbers of new transient sources, but there will be a pressing need for follow-up observations for scientific exploitation, in particular spectroscopic follow-up.

    The increasing popularity of increasing block tariffs (IBT) for water is reflected in Portugal by a virtually universal implementation for residential use. IBT are often supported as a good tool for achieving the goals of equity, water conservation and revenue neutrality but seldom have they been grounded on efficiency justifications.
