The use of natural fiber reinforcement thermoplastic polymer is continuously increasing. This fact is manly due to its advantages as low cost, availability, recyclability, low energy demand and then environmental appeal if compared to synthetics fibers. The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

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

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

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

Family structure and dynamics in DePalma's horror films.

Science.gov (United States)

Gordon, N G

1983-01-01

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

Full Text Available El deficiente desempeño del biodiesel de aceite de palma (BAP a bajas temperaturas constituye su mayor deficiencia de calidad y el limitante para propiciar el uso de este combustible alternativo para motores diesel puro o mezclado en altas proporciones con el combustible diesel convencional derivado del petróleo (ACPM. En este trabajo se evalúan varias alternativas para mejorar las propiedades de flujo a baja temperatura (PFBT del BAP. Mediante la producción del biodiesel utilizando alcoholes ramificados como el isopropanol, isobutanol, 2-butanol e isopentanol se obtienen alquilésteres del aceite de palma con puntos de nube y fl uidez más bajos que los correspondientes a los metilésteres. La sustitución del grupo metil por el isopentil permite obtener reducciones en los puntos de nube y fluidez de 8 y 21 ºC, respectivamente. Los isopropilésteres del aceite de palma poseen un punto de nube 10 ºC menor que el de los metilésteres. El punto de nube de las mezclas BAP-ACPM se incrementa en forma lineal con el contenido del biodiesel en la mezcla. Para las mezclas probadas (B5, B20 y B30 solo se presentan problemas de filtrabilidad del combustible a temperaturas por debajo de -4 ºC. En este trabajo se evaluó la efectividad de dos aditivos comerciales mejoradores de flujo para reducir el punto de obstrucción de filtros en frío (POFF del biodiesel puro y las mezclas probadas. Los resultados obtenidos mostraron que con dichos aditivos solamente es posible obtener reducciones en el POFF de la mezcla B5 cuando se usa la menor de las tres concentraciones de aditivo probadas.

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.

De acordo com os resultados obtidos, a mesorregião da Borborema é a que apresenta as condições climáticas mais favoráveis para o cultivo da palma forrageira. As mesorregiões do Agreste, Sertão e a parte do Litoral, são aptas porém com restrições. No entanto, recomenda-se o cultivo da palma forrageira em todo o território do estado da Paraíba, exceto para a parte costeira da mesorregião do Litoral e região em torno de Areia. Em ambos os casos a inaptidão ocorre em função do excesso de precipitação.

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

The 1677 eruption of La Palma, Canary Islands

Rodríguez Badiola, E.

1996-08-01

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

Full Text Available ABSTRACT Documenting the ethnobotanical knowledge of populations living in protected areas is important both for science and for the effective conservation of these areas, as it can help to clarify the level of dependency that human communities have on local plant resources. Babassu (Attalea speciosa, Arecaceae is one of the most important non-timber forest resources of rural communities in the Amazon. We explored the ethnobotanical knowledge and uses of babassu by riverine populations inhabiting the Tucuruí Lake Protected Areas Mosaic in the eastern Amazon, by examining the diversity, purposes and descriptions of its uses and aspects of its extraction. Data were collected in 2010 and 2014 from 193 families. A total of 1,226 use records were cited representing 60 different uses. Records were classified into nine use-categories; utensils and tools was the most important category, followed by construction and human food. The use with the greatest purpose consensus value among the informants was thatch. Babassu proved to be an important resource for the livelihood of the local communities in providing shelter, food and reliable energy. Most informants lacked knowledge about sustainable practices and management of this resource.

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

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

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.

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

Science.gov (United States)

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

2016-04-01

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

Petrological and geochemical studies of mantle xenoliths from La Palma, Canary Islands

Science.gov (United States)

Janisch, Astrid; Ntaflos, Theodoros

2015-04-01

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

Identification of a new defective SERPINA1 allele (PI*Zla palma) encoding an alpha-1-antitrypsin with altered glycosylation pattern.

Science.gov (United States)

Hernández-Pérez, José M; Ramos-Díaz, Ruth; Pérez, José A

2017-10-01

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

Fueron estudiadas 10 muestras representadas por 3 muestras individuales, 3 muestras binarias y 4 muestras ternarias. Se determinaron la composición en ácidos grasos, el contenido en grasa sólida y la consistencia en el intervalo de temperaturas entre 10ºC y 35ºC. Se aplicó un modelo de regresión múltiple del tipo cúbico especial, siendo que a partir de los coeficientes significativos, se establecieron diagramas triangulares, donde fueron indicadas curvas de nivel. Los resultados demostraron que las interacciones entre los tres componentes no fueron significativas. El contenido en grasa sólida dependió de las grasas de palma y de la semilla de palma y de las interacciones binarias entre ellas. Los coeficientes negativos para esta propiedad demostraron un efecto antagónico, característico de las interacciones eutécticas entre grasas.

Population structure and fruit availability of the babassu palm ( Attalea speciosa Mart. ex Spreng in human-dominated landscapes of the Northeast Region of Brazil

Juliana Loureiro Almeida Campos

Full Text Available ABSTRACT We studied the population structure and fruit availability of the babassu palm, Attalea speciosa, in three human-dominated landscapes located near a rural community in the region of Araripe, in the Northeast Region of Brazil, that were under intense fruit harvest. Fifty 10 x 10 m plots were randomly established in each of the three landscapes, and all individuals of A. speciosa within the plots were classified as seedlings, juveniles or adults, with the height of all adult individuals being measured. An additional 20 individuals were marked in each landscape, and the number of total bunches, fruits per bunch and bunches per palm tree were recorded. The populations of A. speciosa in the three landscapes exhibited an inverted J-shape plot, but pasture and shifting cultivation possessed a significantly higher number of individuals, seedlings and adults than the seasonal semideciduous forest, plus they possessed a greater seedling/adult ratio. Shifting cultivation was found to be favorable for fructification. The present study found that shifting cultivation and pastures are landscape practices that can contribute to the rapid expansion and establishment of A. speciosa, which can become a dominant species in the region of Araripe.

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

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.

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.

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

Oromí Pedro

2008-01-01

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

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.

2011-05-01

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

Full Text Available En Colombia hay diferentes procesos en los cuales se desperdician los residuos, uno de ellos es la obtención de aceite para producir biodiesel a partir de palma aceitera, proceso en el cual se generan importantes cantidades de cuesco de palma, siendo los procesos termoquímicos una de las formas de aprovechamiento energético. El resultado del presente trabajo, es proponer un modelo matemático para el comportamiento del cuesco de palma africana en el proceso de pirolisis y en un estudio posterior para la gasificación. Este trabajo fue desarrollado haciendo una descripción del proceso en un reactor de lecho fijo tubular, el cual se utiliza para ambos procesos, tanto pirolisis como gasificación, con calentamiento directo, siendo muy exotérmico el proceso, identificando la fenomenología en la cual se aplican los conceptos de transferencia de energía, masa. Para el proceso de pirolisis se plantearon los balances de transferencia de energía y masa, despreciando el balance de momento debido a que los gases de síntesis se retiran para que no se generen reacciones heterogéneas, eliminando la fase gaseosa para no tener caídas de presión, por lo cual solo se tuvo en cuenta la fase sólida, lo que permitió que se tratara como una reacción homogénea. Como resultados se generaron dos modelos que describen el comportamiento del reactor en el proceso de pirolisis como un paso inicial para contribuir a la estandarización del proceso a nivel industrial.

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

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

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

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

El objetivo de esta investigación fue desarrollar e implementar un protocolo de crioconservación para embriones cigóticos de palma de aceite (Elaeis guineensis Jacq., como alternativa para complementar la conservación de genotipos de palma ante las dificultades que se presentan en la colección de campo en la actualidad. Se evaluaron las etapas de pre y poscongelación de embriones cigóticos con la metodología de desecación en silica gel a diferentes tiempos de exposición (2, 2,5 y 3 h, seguido de un congelamiento rápido y una etapa de recuperación en un medio de cultivo Murashige y Skoog (1962. Todos los tratamientos de crioconservación fueron evaluados con un fotoperíodo de 16 h luz y 8 h de oscuridad, con una temperatura media de 28 ºC. Previamente se determinó el estado de desarrollo adecuado de los embriones para crioconservar. Además, se realizó la prueba de viabilidad con Tetrazolio para embriones desnudos como un control inicial del lote de semilla solicitado. Se logró establecer un protocolo de crioconservación a partir de embriones cigóticos desnudos de palma, el cual permitió obtener plántulas de embriones congelados en nitrógeno líquido (-196 ºC; alcanzando una sobrevivencia del 84,37% para embriones crioconservados. En cuanto a la diferenciación de estructuras de los embriones crioconservados, el tratamiento de dos horas obtuvo valores para plúmula del 88,9%, radícula del 55,57% y haustorio del 66,7%. Esta metodología permitiría conservar material valioso a largo plazo como copia de seguridad complementaria de la colección de campo y reduciría los costos de mantenimiento y conservación.

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.

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.

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

Vives-Miró, Sònia

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

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

Sanchez-Hernandez, Juan C.; Carbonell, R.; Henriquez Perez, A.; Montealegre, M.; Gomez, L.

2004-01-01

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

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

Pérez Torrado, F. J.

2001-12-01

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

Full Text Available The following article identifies and analyzes the presence of colonial imprints in Serie 1989-2000 by Guatemalan artist Luis Gonzalez Palma (1957. I argue that by citing different versions of the ethnographic portrait visual genre, the Serie builds a temporal arc that extends from the sixteenth century to the Five Hundred Years celebrations (1992. This arc allows us to explore the relation between Art and Anthropology, the representation of Guatemalan indigenous subjects, violence and coloniality in a continued, long-lasting process. In the first part the article delves in a critical and theoretical discussion of the ethnographic turn in art (Kosuth, Foster in a latinamericanist (Camnitzer, Richard, postcolonial and decolonial context (Coronil, Mignolo, Quijano. In the second part, I revise the use of the ethnographic portrait (Brilliant and Mason, Parker Brienen, Lugo Ortiz in racial formations (Omi and Winant in the Americas to further comprehend the presence of this visual genre in Gonzalez Palma´s works, its critical sense, and finally the artist´s proposal to recover “the gaze as power”.

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

FREITAS Suely P.

1998-01-01

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%.

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

Infestation of Palm Trees by Triatomines (Hemiptera: Reduviidae in the State of Bahia, Brazil

Resumo. As palmeiras desempenham papéis importantes como habitats de reprodução e alimentação para triatomíneos silvestres, vetores da doença de Chagas. A ocorrência de triatomíneos em palmeiras peridomiciliares pode aumentar o risco de invasão desses insetos em domicílios e deve ser considerada para desenvolver estratégias de prevenção. Com objetivo de investigar a infestação de palmeiras por triatomíneos no Estado da Bahia e determinar a infecção natural desses insetos por Trypanosoma spp., foram amostradas 183 palmeiras em 12 municípios entre 2006 e 2011 utilizando captura manual e/ou armadilhas adesivas iscadas com camundongos. Os triatomíneos foram detectados em 79 palmeiras (43% das espécies Copernicia prunifera (Mart. Becc., Mauritia flexuosa L. e Attalea spp. (Attalea burretiana Bondar ou Attalea salvadorensis Glassman. Em outras espécies de palmeiras (Syagrus coronata (Mill H.E. Moore, Attalea funifera Mart ex. Spreng e Elaeis guineensis Jacq não foram detectados triatomíneos. Rhodnius neglectus Lent, Triatoma sordida (Stål, e Triatoma pseudomaculata Corrêa & Espínola ocorreram em C. prunifera ao longo do rio São Francisco. No extremo oeste da Bahia, R. neglectus e Psammolestes tertius Lent & Jurberg foram detectados em M. flexuosa, enquanto Triatoma tibiamaculata (Pinto ocorreu em Attalea sp. em áreas urbanas de Salvador. No total, 180 triatomíneos foram capturados, principalmente R. neglectus. A maior taxa de infecção natural (61% foi observada em T. tibiamaculata. Os resultados indicam que pelo menos três espécies de palmeiras são habitats favoráveis para triatomíneos no estado da Bahia e ocorrem no ambiente peridomiciliar, o que pode aumentar a probabilidade de invasão de triatomíneos nas casas.

The screening results from using 15 ISSR primers showed that only 5 of ISSR primers had clear and reproducible bands. Based on the data from the matrix binary analyzed using POPGENE version 3.2, the highest genetic diversity was found in the Sepintun population at 0.0969 average heterozygosis (H and 0.146 average Shannon Index (I. The heterozygosis calculation of the total population (HT was 0.2571. The heterozygosis value within a population (HS=0.0704 was smaller than that between populations (DST=0.1867. Using the clustering analysis program Past version 32 on 43 individuals of D. draco, we found that there were three groups of D. draco. Group A consisted of 8 individuals in the Bengayoan population, group B consisted of 9 units in the Nunusan population and group C consisted of three populations; Tebo, Sepintun and Mandiangin consisted of 10, 8 and 8 individuals. The genetic similarity varied among all populations withthe values between 0.07-0.93.

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

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

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

1999-12-01

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

Full Text Available 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.

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

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

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

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

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

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

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

Full Text Available Patógenos resistentes representam um grande desafio para os hospitais no que se referem aos ao tratamento e as medidas profiláticas. Uma vez no ambiente cepas Gram negativas podem adquirir genes de resistência do solo, da água e dos efluentes hospitalares e assim transmiti-los a outros gêneros. Objetivou-se neste estudo quantificar e qualificar as cepas bacterianas presentes nos pacientes com suspeita de infecção hospitalar e no ambiente em que se encontram internados do Hospital Geral de Palmas. Foram encontradas 14 espécies bacterianas diferentes de 141 amostras, sendo 123 de pacientes e 18 do ambiente hospitalar. Nas amostras dos pacientes destacaram-se a Klebsiella pneumoniae (21,9%, Acinetobacter baumannii (13,8%, Pseudomonas aeruginosa (12,2%, Escherichia coli (11,4%, Serratia marcescens (10, 6% e Staphylococcus aureus (8,9%, dessas observou-se que 80 cepas eram multirresistentes aos antimicrobianos, prevalecendo a Klebsiella pneumoniae (26,3% e a Acinetobacter baumannii (20,0%. As amostras de Aspirado traqueal apresentaram um maior número de cepas multirresistentes. No ambiente prevaleceram a Serratia marcescens, Staphylococcus aureus e Staphylococcus sp. ambas com 22,2%, coletadas de diferentes locais e materiais da UTI como tubo traqueal, Ambu, colchão e monitores. Estes resultados apontam a necessidade de implantação de estratégias administrativas e educativas para reduzir a disseminação de cepas multirresistentes.

2010-01-01

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

Data were obtained in a large extensive census program carried out during the 2007 nesting period using line transects that allowed detectability estimations. We also explored patterns of species richness both at inter-habitat and local scale. Local species richness (species per 0.5 km transects showed an important geographical component, increasing from south to north, from west to east, and reaching maximum values at altitudes around 600-1,000 m a.s.l. It was also positively related to vegetation development (specially in the herbaceous and shrub layer, and negatively associated with urbanization and agriculture. Total bird density reached the highest figures in the ‘monteverde’ (laurel and heath forests ca. 650 aves/km², and in the transition pinewoods-laurel forests (509 aves/km², while the lowest figures were recorded in high altitude shrublands (153 aves/km² and recent lava fields (58 aves/km². The bird species with lower population sizes are Falco [peregrinus] pelegrinoides, Burhinus oedicnemus distinctus, Upupa epops, Carduelis carduelis, Miliaria calandra and Petronia petronia, while the last five species have undergone more negative population trends in the last 15-25 years.

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.

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.

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

Science.gov (United States)

Koschek, P R; Alviano, D S; Alviano, C S; Gattass, C R

2007-10-01

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

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.

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

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

Natural enemies are known to be important in regulating plant populations and contributing to species coexistence (Janzen-Connell effects). The strength of Janzen-Connell effects (both distance- and density-effects) varies across species, but the life history traits that may mediate such a variation are not well understood. This study examined Janzen-Connell effects across the life stages (seed through adult stages) of two sympatric palm species with distinct phenologies and shade tolerances, two traits that may mediate the strength and timing of Janzen-Connell effects. Populations of two common palm species, Attalea phalerata and Astrocaryum murumuru , were studied in Manu National Park, Peru. Seed predation experiments were conducted to assess Janzen-Connell effects at the seed stage. In the post-seed stages, spatial point pattern analyses of the distributions of individuals and biomass were used to infer the strength of distance- and density-effects. Seed predation was both negative distance- and density-dependent consistent with the Janzen-Connell effects. However, only seedling recruitment for asynchronously fruiting Attalea phalerata was depressed near adults while recruitment remained high for synchronously fruiting Astrocaryum murumuru , consistent with weak distance-effects. Negative density-effects were strong in the early stages for shade-intolerant Attalea phalerata but weak or absent in shade-tolerant Astrocaryum murumuru. Distance- and density-effects varied among the life stages of the two palm species in a manner that corresponded to their contrasting phenology and shade tolerance. Generalizing such connections across many species would provide a route to understanding how trait-mediated Janzen-Connell effects scale up to whole communities of species. © The Author 2017.

Full Text Available No ano de 2007, enquanto se desenvolviam os estudos para a criação do Plano Diretor Participativo de Palmas, foi constatada uma significava redução e ocupação irregular das áreas verdes e das matas ciliares na área urbana do município. Como tentativa de conter esses impactos, o poder público transformou as áreas verdes que margeiam os cursos d’água em Unidades de Conservação (UC. No entanto, o que se tem observado é que estas UCs, da forma em que se encontram, não têm atingido os objetivos esperados. O zoneamento ambiental é um dos principais instrumentos de gestão de uma UC, além de ser uma importante fonte de informações para a sua devida categorização. Sendo assim, o presente estudo apresenta o zoneamento ambiental da área proposta da UC Tiúba, levando em consideração a cobertura e uso do solo e as fragilidades ambientais da área, constituído em quatro zonas: sendo duas com o objetivo de proteger as margens dos recursos hídricos e as áreas com vegetação nativa, uma zona temporária para garantir a recuperação das áreas que se encontram degradadas e a outra zona para promover o desenvolvimento de forma sustentável por meio da ocupação controlada da área. ABSTRACT In 2007, during the development of the studies for the creation of a Participative Master Plan of Palmas, it was observed a significant reduction and an illegal occupation of the green areas and the riparian forests in the urban area of the municipality. In an attempt to contain these impacts, the government has turned the green areas bordering waterways in Units of Conservation (UC. However, it has been observed that these UCs, the way they are, have not achieved the expected goals. The environmental zoning is one of the main UC management tools as well as being an important source of information for its proper categorization. Thus, the present study shows the environmental zoning of the proposed area of the Tiúba UC, taking into account

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

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

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

Full Text Available 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.

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

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 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.

Alkaline treatment on piassava fiber with size inferior to 270 mesh was performed to remove impurities. The treatments took place under magnetic stirring and Sodium Hydroxide (NaOH) solution with 2, 4, 6 and 8% of concentration; processing time ranged between 100 and 400 minutes, with intervals of 25 minutes; the main object was to reach the optimum concentration and time. The concentration 2% was used to remove efficiently the impurities without damaging excessively the fiber. The fibers were characterized by means of X-ray diffraction (XRD) and optical microscopy (OM). Fibers presented XRD diffraction peak around 22 deg, due to the crystalline structure of cellulose. By optical microscopy was observed the treatment efficacy of the 2% NaOH solution in removing surface impurities. (author)

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

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.

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.

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.

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

Klügel, Andreas; Hoernle, Kaj A.; Schmincke, Hans-Ulrich; White, James D. L.

2000-03-01

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

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

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

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

2015-05-01

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

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

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

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

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

The first step extraction of cellulose, the second step to obtain the nanoparticles by acid hydrolysis (H 2 SO 4 ). The samples were characterized by: SEM, chemical composition, TGA, FTIR and XRD. The XRD result shows that cellulose is of type I and TGA shows two events at 54 deg C and 370 deg C attributed to mass loss of water and cellulose, respectively. After hydrolysis, X-ray diffraction showed an intense reflection 2θ= 22.3 deg and an increase in the degree of crystallinity to 70% which is an indication of the formation of nanowhiskers. (author)

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

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

A suplementação com farelo de algodão ou com farelo de soja aumentou a excreção de nitrogênio na urina, a concentração de uréia e nitrogênio uréico no plasma e a excreção urinária de uréia e nitrogênio uréico. A associação da palma forrageira ao bagaço de cana-de-açúcar e à uréia, sem o uso de suplementos, permite eficiência de síntese microbiana de 105 gPBmic/kg de NDT consumido. A suplementação com caroço de algodão proporciona maior excreção urinária de alantoína e derivados de purina e melhor eficiência de síntese microbiana, portanto, é a mais indicada nestas condições.The objective of this work was to evaluate the effect of association of forage cactus to sugar cane bagasse and urea on nitrogenous compounds balance and microbial protein synthesis in milk heifers supplemented or not.

Despite broadly overlapping geographic distributions in the central Amazon basin, two congeneric palm species (Attalea attaleoides and Attalea microcarpa) have topographically separated distributions on a local scale in Reserva Ducke near Manaus. Our aim here was to determine if this local scale separation can be linked to (1) seedling stage specialization to different habitat conditions of the two species, and/or (2) environmentally-controlled seed dispersal. We assessed the role of these potential drivers by mapping the local distribution of the two species over a 25-km2 grid and testing for correlation to seed removal and seed germination patterns using seed sowing experiments. 360 seeds of each species were sown in 30 uniformly distributed plots (12 seeds of each species in each plot), and seed removal and germination were subsequently monitored. Adult populations of the two species showed opposite distribution patterns linked to topography. However, there was little evidence for specialization to different habitat conditions at the seedling stage: after 11 months, 26.1% of seeds of A. microcarpa had germinated along the entire topographic gradient, albeit with a tendency toward higher germination in more inclined areas. For A. attaleoides, only 2.2% seeds had germinated, and again along the entire topographic gradient. In contrast, there was evidence for environmentally-controlled seed dispersal: for both species, seed removal was higher in flat areas. Presence of adults did not affect germination or seed removal. Our results suggest that topographically differentiated distributions of A. attaleoides and A. microcarpa may be reinforced by steep slope avoidance by their seed dispersers. A direct environmental control mechanism remains to be identified to explain the consistent topographic associations, but our results show that this mechanism does not work at the seed germination stage.

Slavia takes the Czech path

Biodiesel was the main reason Slavia Capital bought the oil processing company, Palma Tumys, Bratislava last year. The biofuels added to fuel produced from oil are one of the core products of this investment group. But today Slavia is profiting more from the production of edible oils and margarine produced by the Palma Group. It has benefited from the global increase in food prices. But Palma is also profiting from the experience and contacts of its new Czech managers appointed by the new owner. They have found a place in Czech stores for Slovak oils and margarines. In the past the company only used to supply its products to Czech bakers. And they even found a place for biodiesel. Petr Zejdlik is Czech and is the chairman of the board of Palma Group. Matej Valtr, is also Czech and is responsible for managing company strategies. They replaced the former owners, original Slovak privatizers who used to manage the company and did not do badly. They managed to keep one of the biggest Slovak food processing companies in good shape and in profit and j with stable revenues of around 90 mil. EUR. But finally they gave in to international competition from Bunge, Cargill and Archer Daniels Midland and sold the company to a financially strong investor. (author)

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.

In the framework of the project ChArMEx (the Chemistry-Aerosol Mediterranean Experiment, http://charmex.lsce.ipsl.fr/), the variability of aerosol optical, microphysical and radiative properties is examined in three regional background sites on a southwest - northeast (SW-NE) straight line in the middle of the western Mediterranean Basin (WMB). The three sites are on the northward transport pathway of African dust: - Ersa, Corsica Island, France (43.00ºN, 9.36ºW, 80 m a.s.l), - Palma de Mallorca, Mallorca Island, Spain (39.55ºN, 2.62ºE, 10 m a.s.l) and - Alborán, Alboran Island, Spain (35.94ºN, 3.04ºW, 15 m a.s.l). AERONET (AErosol RObotic NETwork) sun-photometer products are mainly used. A preliminary analysis shows that at Ersa and Palma sites the annual aerosol optical depth (AOD) has a similar trend with a peak around 0.2 in July. The winter/spring AOD is lower in Palma than in Ersa, while it is reverse in summer/autumn. The aerosol particle size distribution (and the coarse mode fraction) shows clearly the SW-NE gradient with a decreasing coarse mode peak (and a decreasing coarse mode fraction from 0.5 - 0.35 - 0.2 in July) along the axis Alborán - Palma de Mallorca - Ersa. In addition to the seasonal and annual variability analysis, the analysis of AERONET products is completed with a large variety of ground-based and sounding balloons remote sensing and in situ instruments during the Special Observation Period (SOP) of the ADRIMED campaign in June 2013. The second part of the presentation will focus on the comparison of the observations at Palma de Mallorca and Ersa of the same long-range transported airmasses. The observations include lidar vertical profiles, balloon borne OPC (Optical Particle Counter) and MSG/SEVIRI AOD, among others.

Monitoreamos una población de hormigas zompopas en 2003 y realizamos experimentos de campo en 2006 en el bosque húmedo tropical de la Estación Biológica La Unión en Nicaragua. Los nidos de hormiga zompopa fueron mapeados dentro de una parcela permanente de 6.5 hectáreas. Se estimó lacomposición de especies vegetales en el área del nido de la hormiga, y se realizó un conteo de plántulas dicotiledóneas y plántulas de palmas (monocotiledóneas. Los resultados indican que las hormigas zompopas prefieren defoliar plántulas de especies dicotiledóneas,favoreciendo la regeneración de palmas sobre el nido de las hormigas. Las zompopas favorecen la regeneración de palmas en áreas donde ellas establecen el montículo principal de sus nidos. En el artículo se discuten las implicaciones de estos resultados para la dinámicade la regeneración en bosques húmedos tropicales.

Projections of climate potential for a touristic resort in Mallorca

2010-05-01

Platja de Palma, in the Island of Mallorca, is one of the most popular touristic areas in the Mediterranean with more than 8 million tourist-nights spent per year. Socioeconomic activities undertaken in Platja de Palma are very closely linked with its climate. Therefore, optimization of residential and tourism opportunities in the medium term should necessarily take into account the close interdependence between the evolution of the main atmospheric parameters and the sea, sun and sand tourism (S3), the main tourist model exploited in the area and heavily dependent on the climate. We used the Climate Index for Tourism (CIT, Freitas et al. 2008) to estimate the satisfaction of the S3 tourist in terms of the environmental conditions of the day. The CIT integrates thermal aspects, aesthetic and physical parameters, and derive a measure of perceived satisfaction for the average tourists in terms of three thresholds: unacceptable conditions, acceptable, and ideal. In the first place, we analyzed the evolution of the CIT using data from the proximity weather station in Palma airport for the period 1973-2008. Then, the impact of climate change on the tourism potential of the resort was assessed by calculating the CIT for future climate scenarios. We used regional climate simulation results from the European project ENSEMBLES and for the period 2001-2050. In order to compute the CIT index, daily series of temperature, precipitation, relative humidity, cloudiness and wind near surface are necessary. Model output series are calibrated using observations from Palma airport. In addition, future CIT series are also calibrated using values directly derived from observations. The analysis of the observed period reveals an increase in the number of days per year of acceptable conditions for S3 tourism since 1973 but a decrease in the frequency of ideal conditions, mainly during summer and autumn. Also, ideal conditions in Platja de Palma have increased in frequency during spring

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

In recent years, an increasing number of studies have focussed on resolving the internal structure of ocean island volcanoes. Traditionally, active source seismic experiments have been used to image the volcano edifice. Here we present results using the analysis of compressional to shear (P to S) converted seismic phases from teleseismic events, recorded by stations involved in an active source experiment "TOM-TEIDEVS" (Ibáñez et al., 2008), on the island of Tenerife, Canary Islands. We supplement this data with receiver function (RF) analysis of seismograms from the Canary Islands of Lanzarote and La Palma, applying the extended-time multitaper frequency domain cross-correlation estimation method (Helffrich, 2006). We use the neighbourhood inversion approach of Sambridge (1999a,b) to model the RFs and our results indicate magmatic underplating exists beneath all three islands, ranging from 2 to 8 km, but showing no clear correlation with the age of the island. Beneath both La Palma and Tenerife, we find localized low velocity zones (LVZs), which we interpret as due to partial melt, supported by their correlation with the location of historical earthquakes (La Palma) and recent earthquakes (Tenerife). For Lanzarote, we do not sample the most recently volcanically active region and find no evidence for a LVZ. Instead, we find a simple gradational velocity structure, with discontinuities at ˜4, 10 and 18 km depth, in line with previous studies.

2015-08-01

Here we reconstruct the evolutionary history of Micromeria in the Canary Islands using eight nuclear markers. Our results show two centers of diversification for Micromeria, one in the eastern islands Gran Canaria and Lanzarote, the other in the western islands, Tenerife, La Palma and El Hierro. Suggested directions of inter-island colonization are the following: Gran Canaria to Lanzarote and La Gomera; Tenerife to La Palma (from the paleoisland of Teno), to El Hierro (from the younger, central part), and to La Gomera and Madeira (from the paleoislands). Colonization of La Gomera probably occurred several times from Gran Canaria and Tenerife. The taxonomic implications of these results are discussed. Incongruence among the different markers was evaluated and, using next generation sequencing, we investigated if this incongruence is due to gene duplication. Copyright © 2015 Elsevier Inc.

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.

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.

Evaluar el efecto del consumo de aceites vegetales de alta utilización en Colombia (palma, soya, maíz, girasol y canola sobre las concentraciones sanguíneas de triglicéridos, colesterol total y colesterol-HDL en ratas Wistar. Metodología. Se cuantificaron tocoferoles, tocotrienoles y ácidos grasos de los aceites por cromatografía líquida de alta resolución. A los animales se les suministró un suplemento de 0,2 ml/día de aceite durante 4 semanas; se sacrificó un gru o de cada tratamiento (grupos tratados con aceite de palma, aceite de soya, aceite de maíz, aceite de girasol y aceite de canola para obtener muestras de sangre y cuantificar triglicéridos, colesterol total y colesterol- HDL. Los datos se analizaron según media, desviación estándar, análisis de varianza y Bonferroni. Resultados. No se presentaron diferencias en los triglicéridos a excepción del grupo control versus soya en la tercera semana de tratamiento; se observó también una tendencia a la disminución en el grupo de palma y al aumento en los de girasol y canola. No se encontraron diferencias significativas en colesterol total en ninguna de las semanas de intervención. Se presentaron diferencias en las concentraciones de colesterol HDL en las semanas de tratamiento (p=0,005, una tendencia a la disminución en el grupo de palma y al aumento en el grupo de girasol y maíz. Conclusión. Los aceites modifican el perfil lipídico; el bajo contenido de ácidos grasos saturados, el contenido de tocoferoles y tocotrienoles son favorables para el aumento del colesterol HDL; los tocotrienoles probablemente disminuyen los troglicéridos y atenúan las respuestas desfavorables de los ácidos grasos saturados.

A common challenge in phylogenetic reconstruction is to find enough suitable genomic markers to reliably trace splitting events with short internodes. Here, we present phylogenetic analyses based on genomewide single-nucleotide polymorphisms (SNPs) of an enigmatic avian radiation, the subspecies complex of Afrocanarian blue tits (Cyanistes teneriffae). The two sister species, the Eurasian blue tit (Cyanistes caeruleus) and the azure tit (Cyanistes cyanus), constituted the out-group. We generated a large data set of SNPs for analysis of population structure and phylogeny. We also adapted our protocol to utilize degraded DNA from old museum skins from Libya. We found strong population structuring that largely confirmed subspecies monophyly and constructed a coalescent-based phylogeny with full support at all major nodes. The results are consistent with a recent hypothesis that La Palma and Libya are relic populations of an ancient Afrocanarian blue tit, although a small data set for Libya could not resolve its position relative to La Palma. The birds on the eastern islands of Fuerteventura and Lanzarote are similar to those in Morocco. Together they constitute the sister group to the clade containing the other Canary Islands (except La Palma), in which El Hierro is sister to the three central islands. Hence, extant Canary Islands populations seem to originate from multiple independent colonization events. We also found population divergences in a key reproductive trait, viz. sperm length, which may constitute reproductive barriers between certain populations. We recommend a taxonomic revision of this polytypic species, where several subspecies should qualify for species rank. © 2014 John Wiley & Sons Ltd.

S-Cam 3 is the third generation of a cryogenic camera, based on superconducting tunnel junctions (STJs), for ground-based optical astronomy, deployed at the 4.2 m William Herschel Telescope (WHT) at La Palma (Spain). It exploits a 10x12 pixel array of Ta/Al STJs, covering a field of view of ∼9''x11'' on the sky. The wavelength band extends from 330-750 nm, with a wavelength resolving power of ∼10 at 500 nm. The detectors are operated at ∼285 mK, achieved with a double stage 4 He- 3 He sorption cooler. Each pixel has its own electronic readout chain at room temperature, with a JFET-based charge sensitive preamplifier. The instrument has undergone extensive testing and calibration, followed by the first observation campaign at La Palma in July 2004. This campaign has focused on point sources with time variability, exploiting the instrument's unique combination of spectrophotometry with high time resolution

Soil microbial biomass in an agroforestry system of Northeast Brazil

Directory of Open Access Journals (Sweden)

Rosane C. Rodrigues

2015-01-01

Full Text Available Agroforestry systems (AFS are considered alternative land use options to help prevent soil degradation and improve soil microbial biomass and organic C status. However, it is unclear how different densities of babassu palm [Attalea speciosa (syn. Orbignya phalerata], which is an important tree in Northeast Brazil, affect the soil microbial biomass. We investigated the soil microbial biomass C and activity under AFS with different densities of babassu palm associated with Brachiaria brizantha grass. Soil microbial biomass C (MBC, soil microbial biomass N (MBN, MBC:total organic C ratio, fluorescein diacetate hydrolysis and dehydrogenase activity showed highest values in plots with high density of babassu palm. On the other hand, the respiratory quotient (qCO2 was significantly greater in plots without babassu palm. Brachiaria brizantha in monoculture may promote C losses from the soil, but AFS with high density of babassu palm may increase the potential of soils to accumulate C.Keywords: Enzyme activity, tropical soil, babassu palm, silvopastoral system, soil quality.DOI: 10.17138/TGFT(341-48

In the latest years, the interest for the use of natural fibers in materials composites polymeric has increased significantly due to their environmental and technological advantages. Piassava fibers (Attalea funifera) have been used as reinforcement in the matrix of thermoplastic and thermoset polymers. In the present work (20%, in mass), piassava fibers with particle sizes equal or smaller than 250 μm were incorporated in the polypropylene matrix (PP) no irradiated and polypropylene matrix containing 10 % and 30 % of polypropylene treated by electron-beam radiation at 40 kGy (PP/PPi/Piassava). The composites PP/Piassava and PP/PPi/Piassava were prepared by using a twin screw extruder, followed by injection molding. The composite material samples obtained were treated by electron-beam radiation at 40 kGy, using a 1.5 MeV electron beam accelerator, at room temperature, in presence of air. After irradiation treatment, the irradiated and non-irradiated specimens tests samples were submitted to thermo-mechanical tests, melt flow index (MFI), sol-gel analysis, X-Ray diffraction (XRD) and scanning electron microscopy (SEM).

Salmonella outbreaks related to fruits and vegetables have been reported being lettuce one of the most contaminated. Peracetic acid (PA) at 50 mg/L, sodium dichloroisocyanurate (SD) at 100 mg/L, and the combination of SD at 100 mg/L and babaçu coconut ( Attalea speciosa ) oil detergent at 100 mg/L were applied to fresh lettuce. Natural contaminant microbiota, physicochemical characteristics, and sensory attributes were evaluated. PA and SD reduced mesophilic aerobic counts by 2.1 and 1.5 log cfu/g, respectively. The most efficient treatment in reducing natural microbiota (i.e., PA) was applied alone and in combination with ultrasound (US). It reduced Salmonella enterica Typhimurium counts to undetectable levels (< 1 log cfu/g). US further reduced S. Typhimurium counts by 0.6 log cfu/g in relation to PA, treatment which lessened the pH but increased the titratable acidity of lettuce, but did not cause total color difference. Therefore, the combination of PA and US holds a potential industrial application for sanitization purposes.

Environmental variables, remote sensing and geographical information systems applied to the study of Rhodnius prolixus distribution in Colombia

International Nuclear Information System (INIS)

Guhl, Felipe

2010-01-01

A data base of the entomological survey performer during the Chagas Disease National Control Programme (CHDNCP) in 1997 - 2001 and temporal satellite images masp containing 57 environmental variables were used to build Rhodnius prolixus dispersion predictive maps in Colombia, based on temporal images, Fourier analyses and a discriminative multivaried statistical analyses of the variables studied. The maps show the dispersion of this species and its implication on the Chagas disease transmission in Colombia. A clear division in the predictive dispersion of R. prolixus in two geographical zones was found: one area in the southeast of the Eastern Cordillera associated with the environmental variables used in the present study and a second zone in the Andean Valleys, East of the Eastern Cordillera not much defined by the same variables. This would suggest that the Southwest Region. of Colombia presents a tendency to a wider dispersion of R. prolixus associated to other variables like human intervention. Sylvatic populations of R. prolixus were found recently in Attalea butyracea palm trees in this Region of the Eastern Planes demonstrating the prediction of the presence of this species.

2005-01-01

Determining the prevalence of post-traumatic stress disorder (PTSD) related to the type of war exposure and associated factors in school-aged children from three Colombian towns. Cross-sectional epidemiological study. Representative randomised sample of 493 children aged 5-14. The children were evaluated during 2002 using semi-structured psychiatric interviews and the clinician administered PTSD scale. 167 children were evaluated in La Palma who had been chronically exposed to war, 164 in Arbeláez who had had recent war-exposure and 162 in Sopó who had not been exposed to war. War-related PTSD prevalence was calculated in each municipality. Odds ratio (OR) and chi-square were used for evaluating the association between exposure to war and PTSD and the related risk. Multivariate analysis used the logistic regression model. The affected children required specialised mental health counselling. The prevalence of PTSD resulting from war was 16,8 % in La Palma, 23,2 % in Arbeláez and 1.2% in Sopó. A 19.9 OR (CI 4.7, 119.2), 30,5 Chi-square and p = 0.000 revealed war-related PTSD association and risk for children when comparing the exposed towns to Sopó. The logistic regression showed that geographical closeness to war zone and intense emotional reaction to war increased the probability of war-related PTSD. Vulnerability factors were predominant in war-exposed towns. Poverty, parents' low educational level and child abuse predominated in La Palma. Attention-deficit and psychosomatic disorders were more prevalent in Arbeláez. War affects children's mental health; the children from the exposed towns had 19 times greater probability of war-related PTSD than those from a non-exposed town. Early therapeutic intervention is a public health priority. The results are useful for countries suffering from war, internal conflict and/or terrorism.

To determine an action spectrum for UV-B radiation and the rat lens and to show the effect of the atmosphere and the cornea on the action spectrum. One eye of young female rats was exposed to 5-nm bandwidths of UV-B radiation (290, 295, 300, 305, 310, and 315 nm). Light scattering of exposed and nonexposed lenses was measured 1 week after irradiation. A quadratic polynomial was fit to the dose-response curve for each wave band. The dose at each wave band that produced a level of light scattering greater than 95% of the nonexposed lenses was defined as the maximum acceptable dose (MAD). Transmittance of the rat cornea was measured with a fiberoptic spectrophotometer. The times to be exposed to the MAD in Stockholm (59.3 degrees N) and La Palma (28 degrees N) were compared. Significant light scattering was detected after UV-B at 295, 300, 305, 310, and 315 nm. The lens was most sensitive to UV-B at 300 nm. Correcting for corneal transmittance showed that the rat lens is at least as sensitive to UV radiation at 295 nm as at 300 nm. The times to be exposed to the MAD at each wave band were greater in Stockholm than in La Palma, and in both locations the theoretical time to be exposed to the MAD was least at 305 nm. After correcting for corneal transmittance, the biological sensitivity of the rat lens to UV-B is at least as great at 295 nm as at 300 nm. After correcting for transmittance by the atmosphere, UV-B at 305 nm is the most likely wave band to injure the rat lens in both Stockholm and La Palma.

The Canarian Archipelago is an oceanic island volcanic chain with a long-standing history of volcanic activity (> 40 Ma). It is located off the NW coast of the African continent, lying over a transitional crust of the Atlantic African passive margin. At least 12 eruptions have been occurred on the islands of Lanzarote, Tenerife and La Palma in the last 500 years. Volcanism manifest predominantly as basaltic strombolian monogenetic activity (whole archipelago) and central felsic volcanism (active only in Tenerife Island). We concentrate our studies in the two most active islands, Tenerife and La Palma. In these islands, we tested different methodologies of geodetic monitoring systems. We use a combination of ground- and space-based techniques. At Tenerife Island, a differential interferometric study was performed to detect areas of deformation. DInSAR detected two clear areas of deformation, using this results a survey-based GPS network was designed and optimized to control those deformations and the rest of the island. Finally, using SBAS DInSAR results weak spatial long- wavelength subsidence signals has been detected. At La Palma, the first DInSAR analysis have not shown any clear deformation, so a first time series analysis was performed detecting a clear subsidence signal at Teneguia volcano, as for Tenerife a GPS network was designed and optimized taking into account stable and deforming areas. After several years of activities, geodetic results served to study ground deformations caused by a wide variety of sources, such as changes in groundwater levels, volcanic activity, volcano-tectonics, gravitational loading, etc. These results proof that a combination of ground-based and space-based techniques is suitable tool for geodetic volcano monitoring in Canary Islands. Finally, we would like to strength that those results could have serious implications on the continuous geodetic monitoring system design and implementation for the Canary Islands which is under

Full Text Available The aim of this work is to present aspects related to the ecology of Rhodnius nasutus Stål, 1859 in palms from Chapada do Araripe in Ceará, Brazil. The following five species of palms were investigated: babaçu (Attalea speciosa, buriti (Mauritia flexuosa, carnaúba (Copernicia prunifera, catolé (Syagrus oleracea and macaúba-barriguda (Acrocomia intumescens. Fifth palms were dissected (10 specimens for each species. The overall infestation index was 86%, with a total of 521 triatomines collected. The Trypanosoma cruzi Chagas, 1909 Index was 16.8% and two insects presented mixed infection with Trypanosoma rangeli Tejera, 1920. A precipitin test showed that R. nasutus from palms of Chapada do Araripe are associated with opossum and bird although other possible bloodmeals were observed. Our results showing a high index of infestation of the palms as well as T. cruzi infection, the association of R. nasutus with the most diverse species of palms and proximity of these palms to houses demonstrate the importance of this area for sylvatic T. cruzi transmission and suggest the need for epidemiological surveillance in the region of the Chapada do Araripe.

The Earth Observations Assessment (EOA 2016) is a multiyear project designed to assess the effectiveness of civil earth observation data sources (instruments, sensors, models, etc.) on societal benefit areas (SBAs) for the United States. Subject matter experts (SMEs) provided input and scored how data sources inform products, product groups, key objectives, SBA sub-areas, and SBAs in an attempt to quantify the relationships between data sources and SBAs. The resulting data were processed by Integrated Applications Incorporated (IAI) using MITRE's PALMA software to create normalized relative impact scores for each of these relationships. However, PALMA processing obscures the natural network representation of the data. Any network analysis that might identify patterns of interaction among data sources, products, and SBAs is therefore impossible. Collaborating with IAI, we cleaned and recreated a network from the original dataset. Using R and Python we explore the underlying structure of the network and apply frequent itemset mining algorithms to identify groups of data sources and products that interact. We reveal interesting patterns and relationships in the EOA dataset that were not immediately observable from the EOA 2016 report and provide a basis for further exploration of the EOA network dataset.

Kleinia neriifolia Haw. is an endemic species on the Canarian archipelago, this species is widespread in the coastal thicket of all the Canarian islands. In the present study, genetic diversity and population structure of K. neriifolia were investigated using chloroplast gene sequences and nuclear SSR (simple sequence repeat). The differentiation among island populations, the historical demography, and the underlying evolutionary scenarios of this species are further tested based on the genetic data. Chloroplast diversity reveals a strong genetic divergence between eastern islands (Gran Canaria, Fuerteventura, and Lanzarote) and western islands (EI Hierro, La Palma, La Gomera, Tenerife), this west-east genetic divergence may reflect a very beginning of speciation. The evolutionary scenario with highest posterior probabilities suggests Gran Canaria as oldest population with a westward colonization path to Tenerife, La Gomera, La Palma, and EI Hierro, and eastward dispersal path to Lanzarote through Fuerteventura. In the western islands, there is a slight decrease in the effective population size toward areas of recent colonization. However, in the eastern islands, the effective population size increase in Lanzarote relative to Gran Canaria and Fuerteventura. These results further our understanding of the evolution of widespread endemic plants within Canarian archipelago.

The island of La Palma (Spain), dubbed La Isla Bonita for its beauty, is a UNESCO Biosphere Reserve in the Atlantic Ocean. The island's authorities are aiming for energy self-sufficiency based on wave energy and other renewables. In this research its wave resource is investigated using a 44-years hindcast dataset obtained through numerical modelling and validated with wave buoy records. First, its distribution around La Palma is studied. Significant variations are found, with the largest resource occurring off the north and northwest coasts; the northwest presents operational advantages (proximity to a port). Second, the seasonal variations in this area are studied. Wave energy is provided essentially by powerful NNW-NW swells in winter and autumn, by less energetic NNE-N waves in summer and spring. Finally, the resource is characterised in terms of sea states; it is found that the bulk of the energy is provided by waves between 9.5 s and 13.5 s of energy period and 1.5 m and 3.5 m of significant wave height, so the selection of the Wave Energy Converters to be installed should guarantee maximum efficiency in these ranges.

Full Text Available Bleached cottonseed oil, partially hydrogenated palm oil and margarine were packed in metal cans and white plastic bottles and stored for seven months at room temperature on side bench. Assessment of the stability of the oils towards flavour deterioration was reported. The deterioration of flavour developed from bleached cottonseed oil, partially hydrogenated palm oil and margarine was observed due to increase amount of aldehydes and ketones which play an important role in deterioration of the oils. From the results we found metal can offered suitable and better protection against deterioration than plastic package for cottonseed oil, partially hydrogenated palm oil. While plastic container was better for storing margarine and this is due to the presence of water and salt in margarine where they compose about 16% and 2% respectively.

Aceite de semilla de algodón decolorado, aceite de palma parcialmente hidrogenado y margarina fueron envasados en latas metálicas y botellas de plástico blancas y almacenados durante siete meses a temperatura ambiente en estantes. Se relacionó la evaluación de la estabilidad de los aceites con la deterioración del flavor. La deterioración del flavor producida en aceite de semilla de algodón decolorado, aceite de palma parcialmente hidrogenado y margarina fue observada debido al aumento en la cantidad de aldehídos y cotonas que juegan un importante papel en la deterioración de los aceites. A partir de los resultados obtenidos se encontró que las latas metálicas ofrecieron una adecuada y mejor protección frente a la deterioración que los envases de plásticos para aceite de semilla de algodón y aceite de palma parcialmente hidrogenado. Por otra parte, los recipientes de plástico fueron mejores para el almacenamiento de margarina y esto es debido a la presencia de agua y sales en ella en una proporción del 16% y 2% respectivamente.

Full Text Available This study investigates patterns of forest structure and tree species diversity in an anthropogenic palm grove and undisturbed areas at the seasonally-dry Pinkaití research station, in the Kayapó Indigenous Area. This site, managed by the Conservation International do Brasil, is the most southeastern site floristically surveyed in the Amazon until now. The secondary and a nearby undisturbed forest were sampled in a group of 52 floristic plots of 0.0625-ha (25x25-m where all trees with DBH > 10 cm were measured and identified. The analyses were complemented with other two floristic plots of 1-ha (10x1000-m. The present study has shown that the Pinkaití, like other seasonally-dry forests, have great heterogeneity in forest structure and composition, associated with biotic characteristics of the most important tree species, natural disturbance and history of land-use. The palm grove, moderately dominated by the arborescent palm Attalea maripa (Aubl. Mart., presented high tree species diversity and was floristically similar to undisturbed forests at the study site. It is discussed the importance of large arborescent palms for the seasonally-dry Amazon forests regeneration.Este estudo compara a florística e estrutura e a diversidade de espécies arbóreas de um palmeiral antropogênico e áreas não perturbadas na floresta sazonalmente seca da base de pesquisas ecológicas do Pinkaití, na Terra Indígena Kayapó.

Road traffic crashes (RTC) are an important public health problem, accounting for 1.2 million deaths per year worldwide. In Brazil, approximately 40,000 deaths caused by RTC occur every year, with different trends in the Federal Units. However, these figures may be even greater if health databases are linked to police records. In addition, the linkage procedure would make it possible to qualify information from the health and police databases, improving the quality of the data regarding underlying cause of death, cause of injury in hospital records, and injury severity. This study linked different data sources to measure the numbers of deaths and serious injuries and to estimate the percentage of corrections regarding the underlying cause of death, cause of injury, and the severity injury in victims in matched pairs from record linkage in five representative state capitals of the five macro-regions of Brazil. This cross-sectional, population-based study used data from the Hospital Information System (HIS), Mortality Information System (MIS), and Police Road Traffic database of Belo Horizonte, Campo Grande, Curitiba, Palmas, and Teresina, for the year 2013 for Teresina, and 2012 for the other capitals. RecLink III was used to perform probabilistic record linkage by identifying matched pairs to calculate the global correction percentage of the underlying cause of death, the circumstance that caused the road traffic injury, and the injury severity of the victims in the police database. There was a change in the cause of injury in the HIS, with an overall percentage of correction estimated at 24.4% for Belo Horizonte, 96.9% for Campo Grande, 100.0% for Palmas, and 33.2% for Teresina. The overall percentages of correction of the underlying cause of death in the MIS were 29.9%, 11.9%, 4.2%, and 33.5% for Belo Horizonte, Campo Grande, Curitiba, and Teresina, respectively. The correction of the classification of injury severity in police database were 100.0% for Belo

Full Text Available Urban freight transport is a challenge for Brazilian cities due to the lack of adequate planning for freight flow movement. Public managers also show negligence and a lack of awareness when dealing with urban logistics. Decision-support data on urban freight transport are still scarce, despite being of fundamental value to economic development. With this in mind, this paper presents problems and solutions regarding urban freight transport in Brazilian cities. Data were obtained through a survey conducted in nine cities and analysed by means of descriptive statistics and the successive intervals method. Additionally, a cluster analysis was performed to identify patterns regarding the typical characteristics of each city in order to compare and generalise the perception of retailers regarding problems and solutions at the national level. The results indicate divergent opinions among retailers from different cities, even from cities with similar socioeconomic profiles and urban dynamics. The municipalities which demonstrated the most similarities were (i Betim and Niteroi, in the Southeast of Brazil; (ii Palmas and Quixada, in the North and Northeast, respectively; and (iii Palmas and Caruaru, also in the North and Northeast. The results reinforce the importance of studying the local context and involving stakeholders in the process of planning urban logistics solutions.

La determinación del metal en solución fue llevada a cabo usando el método de la 1,5-difenilcarbazida. Del análisis FTIR se encontró que los grupos hidroxilo y carbonilo presentes en los adsorbentes son los de mayor contribución al proceso de remoción. Además, la modificación mejora la eficiencia del metal de acuerdo con la isoterma de Langmuir de 13 a 4mg/g para el bagazo de palma, y de 22 a 26mg/g para las cáscaras de ñame. Se establece además una mejora en el proceso al trabajar las biomasas en sistema continuo. De las condiciones óptimas de adsorción se determinó que el pH de 2 y el tamaño de partícula de 1mm son las que más favorecen el proceso, y el modelo de Elovich el que mejor lo describe.

The banana weevil (BW), Cosmopolites sordidus (Coleoptera: Curculionidae), is one of the most important insect pests of bananas and plantains. The mobility and the origin of BW infestations at the Canary Islands (Tenerife, La Gomera and La Palma) have been analysed using Random Amplified Polymorphic DNA (RAPD) as molecular markers. Populations from Costa Rica, Colombia, Uganda and Madeira were also included for comparison. One hundred and fifteen reproducible bands from eight primers were obtained. The level of polymorphism in the populations from the Canary Islands (40-62%) was in the range of those found in other populations. Nei's genetic distances, pair-wise fixation index (FST) values indicate that the closest populations are Tenerife populations among themselves (Nei's genetic distance=0.054-0.100; FST=0.091-0.157) and Costa Rica and Colombia populations (Nei's genetic distance=0.049; FST=0.113). Our results indicate the existence of BW local biotypes with limited gene flow and affected by genetic drift. These results are compatible with a unique event of colonization at Tenerife; whereas, the outbreaks in La Gomera and La Palma may come from independent introductions. The Madeira population is phylogenetically and geographically closer to the Canary Islands populations, suggesting that it is the most likely source of the insects introduced in the Canary Islands.

The identification of acetic acid bacteria (AAB) from sound grapes from the Canary Islands is reported in the present study. No direct recovery of bacteria was possible in the most commonly used medium, so microvinifications were performed on grapes from Tenerife, La Palma and Lanzarote islands. Up to 396 AAB were isolated from those microvinifications and identified by 16S rRNA gene sequencing and phylogenetic analysis. With this method, Acetobacter pasteurianus, Acetobacter tropicalis, Gluconobacter japonicus and Gluconacetobacter saccharivorans were identified. However, no discrimination between the closely related species Acetobacter malorum and Acetobacter cerevisiae was possible. As previously described, 16S-23S rRNA gene internal transcribed spacer (ITS) region phylogenetic analysis was required to classify isolates as one of those species. These two species were the most frequently occurring, accounting for more than 60% of the isolates. For typing the AAB isolates, both the Enterobacterial Repetitive Intergenic Consensus (ERIC)-PCR and (GTG)5-PCR techniques gave similar resolution. A total of 60 profiles were identified. Thirteen of these profiles were found in more than one vineyard, and only one profile was found on two different islands (Tenerife and La Palma). Copyright © 2011 Elsevier B.V. All rights reserved.

Chagas disease, caused by Trypanosoma cruzi infection, is a zoonosis of humans, wild and domestic mammals, including dogs. In Panama, the main T. cruzi vector is Rhodnius pallescens, a triatomine bug whose main natural habitat is the royal palm, Attalea butyracea. In this paper, we present results from three T. cruzi serological tests (immunochromatographic dipstick, indirect immunofluorescence and ELISA) performed in 51 dogs from 24 houses in Trinidad de Las Minas, western Panama. We found that nine dogs were seropositive (17.6% prevalence). Dogs were 1.6 times more likely to become T. cruzi seropositive with each year of age and 11.6 times if royal palms where present in the peridomiciliary area of the dog's household or its two nearest neighbours. Mouse-baited-adhesive traps were employed to evaluate 12 peridomestic royal palms. All palms were found infested with R. pallescens with an average of 25.50 triatomines captured per palm. Of 35 adult bugs analysed, 88.6% showed protozoa flagellates in their intestinal contents. In addition, dogs were five times more likely to be infected by the presence of an additional domestic animal species in the dog's peridomiciliary environment. Our results suggest that interventions focused on royal palms might reduce the exposure to T. cruzi infection.

Revisiting Amazonian Plants for Skin Care and Disease

Bruno Burlando

2017-07-01

Full Text Available This review concerns five species of trees and palm trees that occur as dominant plants in different rainforest areas of the Amazon region. Due to their abundance, these species can be exploited as sustainable sources of botanical materials and include Carapa guianensis Aubl., family Meliaceae; Eperua falcata Aubl., family Fabaceae; Quassia amara L., family Simaroubaceae; and Attalea speciosa Mart. and Oenocarpus bataua Mart., family Arecaceae. For each species, the general features, major constituents, overall medicinal properties, detailed dermatological and skin care applications, and possible harmful effects have been considered. The major products include seed oils from A. speciosa and C. guianensis, fruit oil from O. bataua, and active compounds such as limonoids from C. guianensis, flavonoids from E. falcata, and quassinoids from Q. amara. The dermatologic and cosmetic applications of these plants are growing rapidly but are still widely based on empiric knowledge. Applications include skin rehydration and soothing; anti-inflammatory, antiage, and antiparasite effects; hair care; burn and wound healing; and the amelioration of rosacea and psoriasis conditions. Despite a limited knowledge about their constituents and properties, these species appear as promising sources of bioactive compounds for skin care and health applications. An improvement of knowledge about their properties will provide added value to the exploitation of these forest resources.

Full Text Available Fats and oils deteriorate physically and chemically at frying temperatures due to several reasons. The objective of this study was to assess the effect of carvacrol on the oxidative stability of palm oil during a repeated frying process. Potatoes were serially fried in carvacrol-added palm oil, BHT-added palm oil and a control oil (without any antioxidants. After each tenth frying cycle, several chemical analyses were carried out on collected samples to evaluate deterioration in the oils. The free fatty acid, para-anisidine, iodine, and total polar component values of the fresh oil were 0.080, 2.85, 57.1 and 7.5, respectively. These values changed to 0.165, 11.80, 46.7, 11.0, respectively for the control oil; 0.151, 11.28, 49.2 and 10.5 for BHT-added oil; 0.140, 7.19, 51.7, 10.0 for carvacrol-added oil after 40 frying cycles. The results revealed that the use of carvacrol could significantly improve the oxidative stability of palm oil when compared to the control samples. This effect was also comparable to BHT. Using carvacrol in frying oil slowed down the rate of the formation of conjugated dienes and trienes compared to the oil with BHT and the control. The frying process significantly changed the viscosity of the oil samples.Las grasas y aceites se deterioran física y químicamente a las temperaturas de fritura debido a diferentes razones.

These hereditary metabolic diseases are characterized by hyperammonemia and life-threatening hyperammonemic crises. Pharmacological treatment of urea-cycle disorders involves alternative nitrogen-scavenging pathways. Sodium benzoate combines with glycine and phenylacetate/phenylbutyrate with glutamine, forming, respectively, hippuric acid and phenylacetylglutamine, which are eliminated in the urine. Among the ammonia-scavenging drugs, sodium phenylbutyrate is a well-known long-term treatment of urea-cycle disorders. It has been used since 1987 as an investigational new drug, and was approved for marketing in the US in 1996 and the EU in 1999. However, sodium phenylbutyrate has an aversive odor and taste, which may compromise patients’ compliance, and many patients have reported difficulty in taking this drug. Sodium phenylbutyrate granules are a new tasteless and odor-free formulation of sodium phenylbutyrate, which is indicated in the treatment of urea-cycle disorders. This recently developed taste-masked formulation of sodium phenylbutyrate granules was designed to overcome the considerable issues that taste has on adherence to therapy.

Long-distance multipartite quantum communication

International Nuclear Information System (INIS)

Herbst, T.

2014-01-01

This work addresses two long-distance free-space experiments based on multi-photon polarization entanglement. The highlighted measurements were performed between the Canary Islands La Palma and Tenerife, featuring a 143 km horizontal free-space quantum channel. Based on the superposition principle, quantum entanglement constitutes the key building block in quantum information sciences. Its nonclassical correlations lay the ground for exciting new protocols like quantum cryptography, quantum computation or quantum teleportation. Our first experiment targeted on the teleportation of entanglement, also known as entanglement swapping, where the entanglement from two polarization entangled photon pairs 0-1 and 2-3 is swapped onto photons 1-2 and 0-3. This feature constitutes the fundamental resource for so-called quantum repeaters. In the future such devices could be used to subdivide large distances into shorter links and finally extend the entanglement over the whole range by entanglement swapping. In the second experiment we realized four-photon entanglement in the form of a GHZ-state, named after the researchers Daniel Greenberger, Michael Horne and Anton Zeilinger. At the base station on La Palma we employed two sources for polarization-entanglement, generating photon pairs of 808 nm wavelength by spontaneous parametric down-conversion of femtosecond pulsed laser light. In both experiments one of the four photons per pulse was transmitted over a 143 km free-space link to the receiver station on Tenerife, whereas the remaining three photons were measured locally on La Palma. Long term atmospheric turbulences in the near-ground quantum channel were compensated by means of a bi-directional closed-loop tracking of the transceiver telescopes. Despite an average link attenuation of around 30 dB over the 143 km free-space channel, we successfully showed entanglement swapping with a statistical significance of more than 6 standard deviations. Moreover we faithfully

Structural and temporal requirements for geomagnetic field reversal deduced from lava flows.

Reversals of the Earth's magnetic field reflect changes in the geodynamo--flow within the outer core--that generates the field. Constraining core processes or mantle properties that induce or modulate reversals requires knowing the timing and morphology of field changes that precede and accompany these reversals. But the short duration of transitional field states and fragmentary nature of even the best palaeomagnetic records make it difficult to provide a timeline for the reversal process. 40Ar/39Ar dating of lavas on Tahiti, long thought to record the primary part of the most recent 'Matuyama-Brunhes' reversal, gives an age of 795 +/- 7 kyr, indistinguishable from that of lavas in Chile and La Palma that record a transition in the Earth's magnetic field, but older than the accepted age for the reversal. Only the 'transitional' lavas on Maui and one from La Palma (dated at 776 +/- 2 kyr), agree with the astronomical age for the reversal. Here we propose that the older lavas record the onset of a geodynamo process, which only on occasion would result in polarity change. This initial instability, associated with the first of two decreases in field intensity, began approximately 18 kyr before the actual polarity switch. These data support the claim that complete reversals require a significant period for magnetic flux to escape from the solid inner core and sufficiently weaken its stabilizing effect.

Genetic diversity in a population of rhinoclemmys nasuta (Testudines: Geoemydidae) associated with an insular locality in the Choco biogeographic region

2014-01-01

Characterization of the genetic diversity of Rhinoclemmys nasuta population inhabits Isla Palma (Malaga Bay, Valle del Cauca) was carried out using three microsatellite systems (cm72, cm58 and cm"3). In this locality, individuals of R. nasuta are widely distributed in the inland streams and creeks system. 100 to 200 ml of peripheral blood was taken off from ten turtles in five streams of the island, preserving samples in a 0.5 m EDTA. DNA was extracted using salting-out and chelex solution techniques. PCR amplified products were visualized and measured in polyacrylamide gels stained with silver nitrate. successful amplification products were obtained for all systems analyzed, two of which (cm72 and cm3) were found to be monomorphic, while the system cm58 had a high pic (0.698) allowing to estimate the genetic diversity of this population. The observed heterozygosity was low (ho = 0.26) and inbreeding indices fis and fit were high (0.67857 and 0.67881), indicating an excess of homozygotes in each of the rivers and for the all population. The molecular analysis of variance suggested that there is no difference in genetic structure of the population (FST = 0.00075, p= 0.95112). Therefore, the results suggest that the genetic diversity of R. nasutapopulation in Isla Palma was low and exhibited a highly inbred index.

The Gaia SpectroPhotometric Standard Stars (SPSS) survey started in 2006, was awarded almost 450 observing nights and accumulated almost 100 000 raw data frames with both photometric and spectroscopic observations. Such large observational effort requires careful, homogeneous, and automatic data reduction and quality control procedures. In this paper, we quantitatively evaluate instrumental effects that might have a significant (i.e., ≥ 1 %) impact on the Gaia SPSS flux calibration. The measurements involve six different instruments, monitored over the eight years of observations dedicated to the Gaia flux standards campaigns: DOLORES@TNG in La Palma, EFOSC2@NTT and ROSS@REM in La Silla, CAFOS@2.2 m in Calar Alto, BFOSC@Cassini in Loiano, and LaRuca@1.5 m in San Pedro Mártir. We examine and quantitatively evaluate the following effects: CCD linearity and shutter times, calibration frames stability, lamp flexures, second order contamination, light polarization, and fringing. We present methods to correct for the relevant effects which can be applied to a wide range of observational projects at similar instruments. Based on data obtained with BFOSC@Cassini in Loiano, Italy; EFOSC2@NTT in La Silla, Chile; DOLORES@TNG in La Palma, Spain; CAFOS@2.2 m in Calar Alto, Spain; LaRuca@1.5 m in San Pedro Mártir, Mexico (see acknowledgements for more details).

1995-01-01

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

The ground and basement levels are used for commercial spaces, the next levels above for office space and the last three upper levels for apartments, plus a setback penthouse. Each apartment, consisting of living-dining room, services and four double bed-rooms, is layed out lengthwise along a line perpendicular to the Street front, so as to better use the narrow available space, while the natural lighting and ventilation of the inner rooms is achieved by means of numerous shafts distributed throughout the surface. The building features reinforced concrete structure and special concrete panel partitions. The façade combines the same concrete panels, faced with ceramic tiles, with large aluminium windows and artificial, modular shaped, window sills and spandrels.

En una parcela cuadrada, situada en una estrecha calle de la ciudad, se ha levantado este edificio entre medianerías que destina la planta baja y el sótano a locales comerciales, los dos niveles siguientes a oficinas y a viviendas las tres plantas superiores y el ático retranqueado. Cada vivienda —compuesta por estar-comedor, zona de servicio y cuatro dormitorios dobles— se desarrolla en sentido longitudinal, perpendicularmente a la calle, a fin de aprovechar la escasa fachada del edificio, obteniéndose la iluminación y ventilación naturales de las dependencias interiores mediante pequeños patios diseminados en la superficie. La construcción emplea estructura de hormigón armado y tabiquería constituida por piezas especiales de hormigón. En la fachada se combinan las mismas piezas de hormigón revestidas con plaquetas cerámicas, con grandes ventanales de aluminio y antepechos de piedra artificial de conformación reglada.

MAGIC is a system of two 17-m Cherenkov telescopes located on La Palma (Canary islands),sensitive to gamma-rays above 30 GeV. It has been recently upgraded by a second telescope which strongly improves the sensitivity, particularly at low energy. Here we present the status of the MAGIC telescopes and an overview of the recent results obtained in single or stereoscopic mode. We also discuss the real performance of the new stereoscopic system based on Crab Nebula observations.

Spectroscopic classification for 2950 O-, B-, and A-type stars in the CoRoT-fields IRa01, LRa01, and LRa02. Stars are named by their CoRoT-identifier and Coordinates are given. The visual magnitudes were obtained with the Wide Field Camera filter-system of the Isaac Newton Telescope at Roque de los Muchachos Observatory on La Palma and can be converted into Landolt standards, as shown in Deleuil et al. (2009AJ....138..649D). (1 data file).

The Arcetri near-infrared camera ARNICA was built as a users' instrument for the Infrared Telescope at Gornergrat (TIRGO), and is based on a 256x256 NICMOS 3 detector. In this paper, we discuss ARNICA's optical and astronomical performance at the TIRGO and at the William Herschel Telescope on La Palma. Optical performance is evaluated in terms of plate scale, distortion, point spread function, and ghosting. Astronomical performance is characterized by camera efficiency, sensitivity, and spatial uniformity of the photometry.

The infrared light curves of the WTS were generated from time series photometry taken with the WFCAM imager mounted at the prime focus of UKIRT. In order to confirm the transit of WTS-2 b and to help constrain the transit model, on 2010 July 18 we obtained further time series photometry in the Sloan i band using the Wide Field Camera (WFC) on the 2.5m Isaac Newton Telescope (INT) at Roque de Los Muchachos, La Palma.
