    Full Text Available Agriculture has been one of the causes of deforestation, causing environmental impact and soil degeneration, which leads to lower income earned by farmers; hence the need to implement agroforestry systems .This research aims to describe fromthe initial growth of Eugenia stipitata, Inga edulis, and Inga spectabilis to 320 days after emergence. The study took place at the Amazon Research and Conservation Center of the Amazonas State University, during 2014 and 2015. The growth process was evaluated in regards to plant height, stem diameter, number of leaves, and branch length. Plant height and stem diameter were compared over time applying variance analysis. Precipitation was also compared to analyze whether its variations had a direct influence on plant growth. The linear and polynomial models fitted better for thespecies regarding plant height and sprout diameter. Predominance of green leaves compared to yellow and dry ones, as branch length showed significant differences over all the sampling periods. The two-way analysis of variance showed significant differences in the correlation between age and precipitation over plant height and stem diameter. The outcomes led to conclude that Eugenia stipitata had a lower growth than both Inga edulis and Inga spectabilis. Branch production and growth and the number of leaves were also important elements of the growth process.

    International Nuclear Information System (INIS)

    Singh, R.P.

    2016-01-01

    Study of nuclear structure exhibits a wide variety of modes of nuclear excitations. The various modes of excitations reflect different underlying structures nuclei adopt to for a given situation of spin, iso-spin and excitation energy. Trying to understand and reconcile these large variety of underlying structures (and symmetries) in a finite quantal system, like nuclei, is of great interest to physicists. The gamma ray spectrometer called Indian National Gamma detector Array (INGA) (a national collaboration) has given further impetus to these studies due to enhanced photo-peak detection efficiency for gamma rays. In recent years our group in collaboration with universities and institutes have probed the various dynamical symmetries like chirality, shears and gamma bands built over excited configurations. I would discuss some of the recent results from these studies. Further, at IUAC we are working on combining the INGA spectrometer with our hybrid gas-filled mass analyser HYRA for study of heavy nuclei in the forthcoming INGA-HYRA campaign. Some of these developments would also be discussed

    Discrete γ-ray spectroscopy using large array of high purity germanium detectors continue to provide new insights to the structure of an atomic nucleus and its dynamics. The Indian National Gamma Array (INGA) at Tata Institute of Fundamental Research (TIFR) is a powerful spectrometer with a provision of placing 24 Compton suppressed clovers, mounted at different angles with respect to the beam line. A Geant4 based code has been developed to study various features of the array which are of general interest in γ-ray spectroscopy study. Response of the clover detectors have been tested up to 4.8 keV. For the first time geometrical correction factor required in angular distribution, angular correlation measurements have been extracted. The efficiency and add back factor of clover detectors have been successfully reproduced in the simulation. Good agreement has been obtained in simulated and experimental spectrum providing very accurate background estimation even at low energies. Simulations have also been carried out to introduce the concept of a multiplicity filter within the scope of present INGA assembly. In this context some relevant experimental measurements where there can be potential scope of using the simulation results will be discussed

  20. Renewable energy alternatives to mega hydropower: a case study of Inga 3 for Southern Africa

    Science.gov (United States)

    Deshmukh, R.; Mileva, A.; Wu, G. C.

    2018-06-01

    We assess the feasibility and cost-effectiveness of renewable energy alternatives to Inga 3, a 4.8-GW hydropower project on the Congo River, to serve the energy needs of the host country, the Democratic Republic of Congo (DRC), and the main buyer, South Africa. To account for a key uncertainty in the literature regarding the additional economic impacts of managing variable wind and solar electricity, we built a spatially and temporally detailed power system investment model for South Africa. We find that a mix of wind, solar photovoltaics, and some natural gas is more cost-effective than Inga 3 to meet future demand except in scenarios with pessimistic assumptions about wind technology performance. If a low load growth forecast is used, including Inga 3 in the power mix results in higher system cost across all sensitivities. In our scenarios, the effect of Inga 3 deployment on South African power system cost ranges from an increase of ZAR 4300 (US 330) million annually to savings of ZAR 1600 (US 120) million annually by 2035. A cost overrun as low as 20% makes the Inga 3 scenarios more expensive in all sensitivity cases. Including time and cost overruns and losses in transmission from DRC to South Africa make Inga 3 an even less attractive investment. For DRC, through analysis of spatial datasets representing technical, physical, and environmental constraints, we find abundant renewable energy potential: 60 GW of solar photovoltaic and 0.6–2.3 GW of wind located close to transmission infrastructure have levelized costs less than US 0.07 per kWh, or the anticipated cost of Inga 3 to residential consumers.

    2007-01-01

    We sampled Inga Busk species caterpillars weekly in the cerrado on 15 plants of Diospyros burchellii Hern. (Ebenaceae) from January 2002 to December 2003, on 30 plants of Caryocar brasiliense (Caryocaraceae) from July 2003 to June 2004, and since 1991 on several other plant species. In total we found 15 species of Inga on cerrado host plants. Nine species were very rare, with only one to five adults reared. The other six species occurred throughout the year, with higher abundance during the dry season, from May to July, coinciding with overall peaks of caterpillar abundance in the cerrado. Caterpillars of the genus Inga build shelters by tying and lining two mature or old leaves with silk and frass, where they rest and develop (a common habit found in Oecophorinae). The final instar builds a special envelope inside the leaf shelter, where it will complete the larval stage and pupate. The species are very difficult to distinguish in the immature stages. External features were useful in identifying only four species: I. haemataula (Meyrick), I. phaecrossa (Meyrick), I. ancorata (Walsingham), and I. corystes (Meyrick). These four species are polyphagous and have wide geographical distributions. In this paper we provide information on the natural history and host plants of six Inga species common on cerrado host plants, for which there are no reports in the literature.

  6. The generalist Inga subnuda subsp. luschnathiana (Fabaceae): negative effect of floral visitors on reproductive success?

    Science.gov (United States)

    Avila, R; Pinheiro, M; Sazima, M

    2015-05-01

    Inga species are characterised by generalist or mixed pollination system. However, this feature does not enhance reproductive rates in species with very low fruit set under natural conditions. Some ecological and genetic factors are associated with this feature, and to test the effect of massive visits on pollination success in Inga subnuda subsp. luschnathiana, we studied the efficacy of polyads deposited on stigmas of flowers isolated from visitors and polyads exposed to visitors. The proportion of polyads fixed in stigmas decreased after exposure to visitors (24 h) in comparison to stigmas isolated from visitors (hummingbirds, bees, wasps, hawkmoths and bats), and fruit set was very low. Furthermore, nectar production, sugar composition and other floral biology traits were evaluated. Increased nectar production, sugar availability and sucrose dominance during the night indicates adaptation to nocturnal visitors and supports their role as main pollinators; although the brush-flower morphology, time of anthesis, nectar dynamics and chemical composition also allow daytime visitors. Thus the species is an important resource for a diverse group of floral visitors. We conclude that excess visits (diurnal and nocturnal) are responsible for the decrease in fixed polyads in stigmas of I. subnuda subsp. luschnathiana flowers, thus contributing, with others factors, to its low fruit set. Therefore, the generalist pollination system does not result in reproductive advantages because the low fruit set in natural conditions could be the result of a negative effect of visitors/pollinators. © 2014 German Botanical Society and The Royal Botanical Society of the Netherlands.

    As part of our search of bioactive saponins from Brazilian plants, phytochemical study of the seeds of Inga laurina led to the isolation of a new complex triterpenoid saponin, named ingasaponin. It is the first saponin isolated from a species of Inga genus. It was isolated by using chromatographic methods and its structural elucidation was performed using detailed analyses of (1)H and (13)C NMR spectra including 2D-NMR spectroscopic techniques and chemical conversions. Its structure was established as 21-[[(2E,6S)-6-[[6-deoxy-4-O-[(2E,6S)-6-[(β-D-glucopyranosyl)oxy]-2,6-dimethyl-1-oxo-2,7-octadienyl]-[(β-D-glucopyranosyl)oxy]-2,6-dimethyl-1-oxo-2,7-octadienyl]-[(β-D-glucopyranosyl)oxy]-2,6-dimethyl-1-oxo-2,7-octadienyl]-[(β-D-glucopyranosyl)oxy]-2-(hydroxymethyl)-6-methyl-1-oxo-2,7-octadienyl]oxy]-16-hydroxy-3-[[O-β-D-xylopyranosyl-(1 → 2)-O-α-L-arabinopyranosyl-(1 → 6)-2-(acetylamino)-2-deoxy-β-D-glucopyranosyl]oxy]-(3β,16α,21β)-olean-12-en-28-oic acid O-α-L-arabinofuranosyl-(1 → 4)-O-[β-D-glucopyranosyl-(1 → 3)]-O-6-deoxy-α-L-mannopyranosyl-(1 → 2)-β-D-glucopyranosyl ester (1).

    Plant protease inhibitors (PIs) are elements of a common plant defense mechanism induced in response to herbivores. The fall armyworm, Spodoptera frugiperda, a highly polyphagous lepidopteran pest, responds to various PIs in its diet by expressing genes encoding trypsins. This raises the question of whether the PI-induced trypsins are also inhibited by other PIs, which we posed as the hypothesis that Inga laurina trypsin inhibitor (ILTI) inhibits PI-induced trypsins in S. frugiperda. In the process of testing our hypothesis, we compared its properties with those of selected PIs, soybean Kunitz trypsin inhibitor (SKTI), Inga vera trypsin inhibitor (IVTI), Adenanthera pavonina trypsin inhibitor (ApTI), and Entada acaciifolia trypsin inhibitor (EATI). We report that ILTI is more effective in inhibiting the induced S. frugiperda trypsins than SKTI and the other PIs, which supports our hypothesis. ILTI may be more appropriate than SKTI for studies regarding adaptive mechanisms to dietary PIs. © 2017 Wiley Periodicals, Inc.

  13. Using targeted enrichment of nuclear genes to increase phylogenetic resolution in the neotropical rain forest genus Inga (Leguminosae: Mimosoideae

    Directory of Open Access Journals (Sweden)

    James A Nicholls

    2015-09-01

    Full Text Available Evolutionary radiations are prominent and pervasive across many plant lineages in diverse geographical and ecological settings; in neotropical rainforests there is growing evidence suggesting that a significant fraction of species richness is the result of recent radiations. Understanding the evolutionary trajectories and mechanisms underlying these radiations demands much greater phylogenetic resolution than is currently available for these groups. The neotropical tree genus Inga (Leguminosae is a good example, with ~300 extant species and a crown age of 2-10 MY, yet over 6kb of plastid and nuclear DNA sequence data gives only poor phylogenetic resolution among species. Here we explore the use of larger-scale nuclear gene data obtained though targeted enrichment to increase phylogenetic resolution within Inga. Transcriptome data from three Inga species were used to select 264 nuclear loci for targeted enrichment and sequencing. Following quality control to remove probable paralogs from these sequence data, the final dataset comprised 259,313 bases from 194 loci for 24 accessions representing 22 Inga species and an outgroup (Zygia. Bayesian phylogenies reconstructed using either all loci concatenated or a subset of 60 loci in a gene-tree/species-tree approach yielded highly resolved phylogenies. We used coalescent approaches to show that the same targeted enrichment data also have significant power to discriminate among alternative within-species population histories in the widespread species I. umbellifera. In either application, targeted enrichment simplifies the informatics challenge of identifying orthologous loci associated with de novo genome sequencing. We conclude that targeted enrichment provides the large volumes of phylogenetically-informative sequence data required to resolve relationships within recent plant species radiations, both at the species level and for within-species phylogeographic studies.

    Fall, Latsoucabe

    2010-09-15

    Harnessing Africa's huge hydropower potential should be made a priority for the sustainable development of the Continent. Particularly, Grand Inga hydropower project in DRC, due to its gigantic size (40,000 MW) and favourable natural characteristics, could be 'Africa's flagship Project of the 21st Century' offering enormous comparative advantages and opportunities for the benefits of the entire African Continent. Nevertheless, to make it a feasible and palpable 'Model Project', capable of producing clean and affordable energy, the paper tries to respond to key questions on the several daunting challenges to address for its sustainable, cost-effective and timely development and operation.

    Flood events in riparian forests of southern Brazil, can be characterized as unpredictable and of low magnitude with an average duration of less than 15 days. Inga marginata is an evergreen tree which grows in Southeast South America on a wide range of environments, including riparian forests. In this paper, the interactive effects of the light environment and soil flooding on morphological parameters of I. marginata were examined. Seedlings were acclimated in two contrasting light conditions: sun or shade for 30 days. Sun and shade plants were subjected to soil flooding for two periods; five or 15 days. After 5 days, the interaction between flooding and light did not affect growth, chlorophyll content and dry mass or the root-shoot ratio. After 15 days, flooded plants from the sunny treatment had a lower shoot dry mass compared to control sun plants and flooded plants from the shaded treatment. Moreover, the higher dry mass observed for shade plants compared to sun plants, following flooding, can also be directly associated with a higher content of soluble sugars. Shade plants of I. marginata showed a greater acclimation to soil waterlogging. This acclimation appears to be associated with a larger accumulation of soluble sugars compared to non-flooded plants. The responses observed on the shade plants appear to be decisive to indicate the use of I. marginata in degraded areas.

    Planting of native trees for habitat restoration is a widespread practice, but the consequences for the retention and transmission of genetic diversity in planted and natural populations are unclear. Using Inga vera subsp. affinis as a model species, we genotyped five natural and five planted populations in the Atlantic forest of northeastern Brazil at polymorphic microsatellite loci. We studied the breeding system and population structure to test how much genetic diversity is retained in planted relative to natural populations. We then genotyped seedlings from these populations to test whether genetic diversity in planted populations is restored by outcrossing to natural populations of I. vera. The breeding system of natural I. vera populations was confirmed to be highly outcrossing (t = 0.92; FIS = -0.061, P = 0.04), with populations showing weak population substructure (FST = 0.028). Genetic diversity in planted populations was 50% less than that of natural populations (planted: AR = 14.9, HO = 0.865 and natural: AR = 30.8, HO = 0.655). However, seedlings from planted populations showed a 30% higher allelic richness relative to their parents (seedlings AR = 10.5, parents AR = 7.6). Understanding the processes and interactions that shape this system are necessary to provide ecologically sensible goals and successfully restore hyper-fragmented habitats. Future restoration plans for I. vera must consider the genetic diversity of planted populations and the potential for gene flow between natural populations in the landscape, in order to preserve ecological interactions (i.e. pollination), and promote opportunities for outcrossing.

  9. “Yo soy jaguar”. Una lectura cruzada entre la filosofia y la antropología sobre los enunciados con contenido animal en la comunidad Inga

    Jennifer Andrea Rivera Zambrano

    2017-05-01

    Full Text Available This paper gives an account of a conceptual exercise of interpretation which lies between philosophy and anthropology. Its approach is the idea that, in contrast with notions of symbolic association, as a state of becoming, the descriptions which still persist in the Inga and Kamëntsa indigenous communities of the relationship between their sabedores (“knowers”/wise men/shamans and “jaguars” may be understood as the affective relations of men who experience forces that are not theirs and that during that process, they summon something which is especially creative in themselves as a way of achieving a trans-codification between the animal and the human in the creation of individuation. Its approach is based on the conceptual framework of the contemporary philosophy of Deleuze and Guattari, with the aim of establishing a dialogue between that philosophy and anthropology´s understanding of the “being a jaguar” phenomenon and providing an interpretation of the zoo-anthropomorphic occurrence with the use of the concept of becoming. Towards that end: i the construction of individuations is determined by an analysis of the accounts of sabedores of the Inga and Kamëntsa indigenous communities, which; ii reveals the conceptualization of this particular relationship as becoming in the light of some developments which are in line with the notions of “the jaguar man” of the anthropologist Reichel Dolmatoff; iii Finally, the effects of becoming as a creation of meaning are explained.

    A 6.5 kDa serine protease inhibitor was purified by anion-exchange chromatography from the crude extract of the Inga umbratica seeds, containing inhibitor isoforms ranging from 6.3 to 6.7 kDa and protease inhibitors of approximately 19 kDa. The purified protein was characterized as a potent inhibitor against trypsin and chymotrypsin and it was named I. umbratica trypsin and chymotrypsin inhibitor (IUTCI). MALDI-TOF spectra of the IUTCI, in the presence of DTT, showed six disulfide bonds content, suggesting that this inhibitor belongs to Bowman-Birk family. The circular dichroism spectroscopy indicates that IUTCI is predominantly formed by unordered and beta-sheet secondary structure. It was also characterized, by fluorescence spectroscopy, as a stable protein at range of pH from 5.0 to 7.0. Moreover, this inhibitor at concentration of 75 microM presented a remarkable inhibitory activity (60%) against digestive serine proteases from boll weevil Anthonomus grandis, an important economical cotton pest.

Bambino covers the years 1945–1981, but also contains flashbacksto pre-war memory of Stettin and to the suppressed experiences of the new post-war inhabitants, as well as ‘flash-forwards’ to post-1989, post-communist reality; Ku słońcu covers 1981 to the first decade of 2000s. It will show how the novels portray these transformations through the experience primarily of women (but not only — in Bambino, through the main protagonists: Ula (formerly Ulrike, Anna and Marysia, and through that of the hidden narrator Magda (Marysia’s daughter born in the same year as the author, Iwasiów, 1963; and in Ku słońcu, primarily through the experience of Magda herself, as well as through that of two generations of ‘feminist’ academics: Małgorzata and Sylwia (in which it is hard not to perceive the personal experience of the author, though she is at pains to emphasize elsewhere that her work is a collective biography of the city, not so much of herself. The analysis follows Katarzyna Chmielewska’s supposition that contemporary Polish fiction dealing with the past ‘constantly oscillates between memory and genealogy’, and that it raises raw issues not yet addressed by historians; it also derives inspiration from the new ‘postdependency’ studiesproposed by Hanna Gosk and Ryszard Nycz. It also attempts to capture the specific nature of Iwasiów’s use of language, her style of feminism, her method of portraying place, and the connections in her prose between place and memory.

Este estudo teve como objetivo avaliar os efeitos da inoculação com bactérias fixadoras de nitrogênio (N e da adubação nitrogenada no crescimento e qualidade de mudas de I. laurina. O experimento teve duração de 170 dias, e as mudas foram cultivadas em tubetes plásticos com 115 cm3 de capacidade, contendo uma mistura 9: 1 em volume de HS Florestal® e pó de fibra de coco como substrato. Foram analisados seis tratamentos, sendo quatro inoculações (Bradyrhizobium japonicum 1 - BJ1, Rhizobium miluonense - RM, Bradyrhizobium japonicum 2- BJ2 e Burkholderia cepacia - BC, o controle positivo - C+ (sem inoculação e com adubação nitrogenada semanal, 60 mg dm3 de N, na forma de ureia e o controle negativo - C- (sem inoculação e sem adubação nitrogenada. Os tratamentos com inoculação foram pouco efetivos em relação ao crescimento das mudas, visto que as médias das variáveis de crescimento, da massa foliar específica (MFE e do índice de qualidade de Dixon (IQD foram significativamente superiores no C+, em comparação com os demais tratamentos. No entanto, os isolados RM e BJ2 foram efetivos na produção de nódulos, pois apresentaram os maiores valores médios da massa de matéria seca de nódulos (MSN.

    Full Text Available The aim of the paper is twofold: Firstly, to examine the effects of cutbacks related to the the economic collapse on the motivating factors among nurses in primary health care and, secondly, to examine the effects of the cutbacks on the knowledge sharing within the same group. A qualitative method, the Vancouver-school of doing phenomenology, was used, involving a purposeful sample of ten nurses in primary health care. The results indicate that the cutbacks increased pressure, fatigue, lack of time and employment insecurity among the participants. Continuing education and professional development was negatively affected and job security and salaries became stronger motivating factors than before. Lack of time and a heavy workload hindered spontaneous knowledge sharing while organized knowledge sharing was less affected. From thisit can be learned that cutbacks can have serious effects on motivationalfactors among health care professionals.Tilgangur greinarinnar er tvíþættur: Í fyrsta lagi að greina áhrif niðurskurðar í kjölfar efnahagshrunsins á helstu starfshvata hjúkrunarfræðinga í heilsugæslu og í öðru lagi að greina áhrif niðurskurðarins á þekkingarmiðlun innan sama hóps. Rannsóknaraðferðin var eigindleg, byggð á Vancouver-skólanum í fyrirbærafræði. Tekin voru hálfstöðluð viðtöl við tíu hjúkrunarfræðinga sem allir starfa í heilsugæslu og voru þeir valdir með tilgangsúrtaki. Niðurstöður eru þær helstar að í kjölfar niðurskurðarins upplifðu þátttakendur aukið álag, þreytu, tímaskort og óvissu. Laun og starfsöryggi reyndust sterkari starfshvatar en áður og neikvæð áhrif komu fram á endurmenntun og starfsþróun. Tímaskortur og verkefnaálag hamlaði þekkingarmiðlun sem átti sér stað fyrir tilviljun en tekist hefur að standa vörð um þekkingarmiðlun sem var í skipulegu ferli.

    Energy Technology Data Exchange (ETDEWEB)

    Guther, F. [Ingenieurbuero Guther, Hausham (Germany)

    2000-07-01

    Most accidents in gas supply are gas explosions wilfully caused for the purpose of suicide, killing, stealing gas, or causing damage to property. The gas industry attempts to minimize these manipulations by means of practicable technical, organisational and communicative measures. [German] Die vorsaetzliche Herbeifuehrung von Gasexplosionen mit der Absicht der Selbsttoetung, der Toetung Dritter, des Gasdiebstahls oder der Sachbeschaedigung stellt die schwerwiegendste Unfallursache in der oeffentlichen Gasversorgung dar. Dem Gasfach kommt damit noch staerker als bisher die Aufgabenstellung zu, mit praktikablen technischen und eventuell organisatorischen wie auch kommunikativen Moeglichkeiten diese Manipulationsfaelle auf ein Mindestmass zu reduzieren.

    International Nuclear Information System (INIS)

    Hulbert, S.L.

    1991-01-01

    A significant reaction is reported between gold surfaces and an indium-gallium eutectic liquid alloy often used to transfer heat away from optical elements in high power synchrotron radiation beamlines. This reaction proceeds at the slightly elevated temperatures (70 degrees C) typical of conservative bakeouts used to achieve ultrahigh vacuum in the chambers which house these optical elements (mirrors, gratings, and crystals) without damaging their highly precise figure and finish. The nature and extent of this reaction is discussed, based mostly on the experience gained recently during the vacuum commissioning of two mirror chambers for a VUV wiggler-based synchrotron radiation beamline. 2 refs., 5 figs

    The chemical interaction of the indium-gallium eutectic with Al and Al-base alloys is studied by X-ray diffraction, optical microscopy, and electron microscopy. Experimental data are presented that shed light on the reaction mechanism and the diffusion processes responsible for the subsequent disintegration of the material and its dissolution in water. Mechanical tests show that the activation of aluminum leads to a transition from plastic to brittle fracture [ru

Phenetic relationships were studied among 75 specimens belonging to the sevenrecognized taxa, in order to evaluate their validity. A morphological matrix of 46 characters was ana-lyzed by clustering and conglomerate methods. The dendrogram and the principal components analyses(PCA show six groups, consequently six species can be clearly recognized:I. saltensis, I. marginata,I. laurina, I. virescens, I. affinis, andI. uraguensis.

    Curves of differential capacitance in the interfaces Hg/H 2 O, Ga/H 2 O, (In-Ga)/H 2 O and (Tl-Ga)H 2 O in 0.05 M Na 2 SO 4 solutions with different additions of n-butanol have been obtained by the bridge method at a frequency of 420 Hz and temperature of 32 deg C. The method of regression analysis of the curves permitted ascertaining the adsorption parameters of n-butanol for the range of charges q, where there is no chemisorption of H 2 O dipoles. The data obtained suggested that the difference in the adsorption behaviour of organic molecules on the metals studied in the range of higher negative charges is largely determined by different electron electrochemical work functions, the definition being given by S.

  2. Dinitrogen fixation by legume shade trees and direct transfer of fixed N to associated cacao in a tropical agroforestry system.

    2015-02-01

    Natural abundance of (15)N (δ (15)N) was determined in bulk soil, rhizospheric soil and vegetation in an organically managed cacao (Theobroma cacao L.) plantation with Inga edulis Mart. legume trees (inga) as the principal shade for studying the nitrogen (N) cycle in the system. Cacao without contact with legumes in an adjacent plantation was used as the reference for N2 fixation and direct N transfer calculations. Bulk and rhizospheric soils contained 72 and 20%, respectively, of whole- system N. No vegetation effect on δ (15)N in rhizospheric soil was detected, probably due to the high native soil N pool. Fine roots of the cacaos associated with inga contained ∼35% of N fixed from the atmosphere (Nf) out of the total N. Leaves of all species had significantly higher δ (15)N than fine roots. Twenty percent of system Nf was found in cacao suggesting direct N transfer from inga via a common mycelial network of mycorrhizal fungi or recycling of N-rich root exudates of inga. Inga had accumulated 98 kg [Nf] ha(-1) during the 14-year history of the plantation. The conservative estimate of current N2 fixation rate was 41 kg [Nf] ha(-1) year(-1) based on inga biomass only and 50 kg [Nf] ha(-1) year(-1) based on inga and associated trees. © The Author 2015.

    Coevolutionary models suggest that herbivores drive diversification and community composition in plants. For herbivores, many questions remain regarding how plant defenses shape host choice and community structure. We addressed these questions using the tree genus Inga and its lepidopteran herbivores in the Amazon. We constructed phylogenies for both plants and insects and quantified host associations and plant defenses. We found that similarity in herbivore assemblages between Inga species was correlated with similarity in defenses. There was no correlation with phylogeny, a result consistent with our observations that the expression of defenses in Inga is independent of phylogeny. Furthermore, host defensive traits explained 40% of herbivore community similarity. Analyses at finer taxonomic scales showed that different lepidopteran clades select hosts based on different defenses, suggesting taxon-specific histories of herbivore-host plant interactions. Finally, we compared the phylogeny and defenses of Inga to phylogenies for the major lepidopteran clades. We found that closely related herbivores fed on Inga with similar defenses rather than on closely related plants. Together, these results suggest that plant defenses might be more evolutionarily labile than the herbivore traits related to host association. Hence, there is an apparent asymmetry in the evolutionary interactions between Inga and its herbivores. Although plants may evolve under selection by herbivores, we hypothesize that herbivores may not show coevolutionary adaptations, but instead "chase" hosts based on the herbivore's own traits at the time that they encounter a new host, a pattern more consistent with resource tracking than with the arms race model of coevolution.

  8. Electrical double layer structure at the gallium metals in a methanol solution of a surface-inactive electrolyte

    Emets, V.V.

    1997-01-01

    The structure of double electric layer on Ga-, In-Ga- and Tl-Ga-electrodes in methanol solutions of surface-inactive electrolyte has been studied. It is shown that in the absence of chemisorption interaction between metal and solvent, the distance of the nearest approach of methanol dipoles to the surface of Ga-, In-Ga- and Tl-Ga-electrodes is practically the same. Accordingly, the specificity of the metals contact with solvent is reduced solely to their chemisorption interaction. In the zero charge area and for negative charges the chemisorption interaction with methanol molecules increases in the sequence Tl-Ga< In-Ga< Ga. The growth correlates both with the metals acceptor ability towards electron, which is characterized by the work of metal electron escape to vacuum, and donor ability of the solvent characterized by its donor number

    The objective of this project is to develop a computerized statistical model with the Integrated Neural-Genetic Algorithm (INGA) for predicting the probability of long-term leak of wells in CO2 sequestration operations. This object has been accomplished by conducting research in three phases: 1) data mining of CO2-explosed wells, 2) INGA computer model development, and 3) evaluation of the predictive performance of the computer model with data from field tests. Data mining was conducted for 510 wells in two CO2 sequestration projects in the Texas Gulf Coast region. They are the Hasting West field and Oyster Bayou field in the Southern Texas. Missing wellbore integrity data were estimated using an analytical and Finite Element Method (FEM) model. The INGA was first tested for performances of convergence and computing efficiency with the obtained data set of high dimension. It was concluded that the INGA can handle the gathered data set with good accuracy and reasonable computing time after a reduction of dimension with a grouping mechanism. A computerized statistical model with the INGA was then developed based on data pre-processing and grouping. Comprehensive training and testing of the model were carried out to ensure that the model is accurate and efficient enough for predicting the probability of long-term leak of wells in CO2 sequestration operations. The Cranfield in the southern Mississippi was select as the test site. Observation wells CFU31F2 and CFU31F3 were used for pressure-testing, formation-logging, and cement-sampling. Tools run in the wells include Isolation Scanner, Slim Cement Mapping Tool (SCMT), Cased Hole Formation Dynamics Tester (CHDT), and Mechanical Sidewall Coring Tool (MSCT). Analyses of the obtained data indicate no leak of CO2 cross the cap zone while it is evident that the well cement sheath was invaded by the CO2 from the storage zone. This observation is consistent

    Full Text Available Ce témoignage de Cayo Inga est un document important qui retrace les succès des premières années de la pénétration espagnole au Pérou, de la côte de Tumbes à la ville de Cuzco. Sa valeur exceptionnelle tient à la qualité de l'informateur-membre du lignage inca et au fait qu'il ait été un témoin personnel des faits qu'il décrit. Par ce manuscrit, nous savons que Waskar Inga connut opportunément l'invasion étrangère à partir de la côte de Tumbes et que les Espagnols exigèrent une rançon au captif Atao Wallpa lui promettant de relâcher après. Nous sommes également renseignés sur le fameux pillage du temple de Pachacamac, sur la dramatique demande d'Atao Wallpa suppliant d'être exilé en Espagne et sur l'emprisonnement de Mango Inga Yupangui. Enfin, ce manuscrit éclaircit quelques faits quant aux sièges de la ville de Cuzco et de celle de Lima en 1536. El testimonio de Cayo Inga, es un documento excepcional para rehacer los sucesos de los primeros años de la penetración española en el Perú, de la costa tumbesina a la ciudad del Cuzco primero por la calidad del informante miembro del linaje Inca y segundo por su presencialidad en el lugar de los hechos. Este manuscrito, aclara que Waskar Inga conoció oportunamente la invasión de la costa tumbesina por los extranjeros y refiere que los españoles exigieron al cautivo Atao Wallpa un rescate, prometiéndole soltarlo después. Reseña a la vez el famoso saqueo del adoratorio de Pachacamac, el dramático pedido de Atao Wallpa para que lo exiliaran a España y el prendimiento de Mango Inga Yupangui, finalmente aporta datos sobre los asedios de la ciudad del Cuzco y de Lima en 1536. Cayo Inga's testimony is a document of exceptional value in the retracing of the events of the first years of the Spanish invasion and occupation of the country from Tumbes to Cuzco. It is remarkable for the quality of the source of information, since the reporter was both a member of the Inca

    Element-specific unoccupied electronic states of Cu(In, Ga)S{sub 2} were studied as a function of the In/Ga ratio by combining X-ray absorption spectroscopy with density functional theory calculations. The S absorption edge shifts with changing In/Ga ratio as expected from the variation of the band gap. In contrast, the cation edge positions are largely independent of composition despite the changing band gap. This unexpected behavior is well reproduced by our calculations and originates from the dependence of the electronic states on the local atomic environment. The changing band gap arises from a changing spatial average of these localized states with changing alloy composition.

    Full Text Available An analysis of the large existing indigenous cultural diversity in South America as the initial part of the study and support of research is presented. It is also a reflection from the perspective of different authors on the thinking of man in relation to nature, archetypes, cosmogony and rituals. It is also woven with the history of the peoples or ethnic communities of Kamentzá and Inga. The inhabitants of Sibundoy Valley, Putumayo Colombia show a strong influence of Eastern and other Amerindian cultures that have had a great relevance and importance on other cultures of the continent. Similarly, it treats the nature of the Indian art and aesthetics as an important aspect in the development of cosmology and the spirituality embodied in the different objects and in the aesthetics in other elements of cultural elements proper to the Kamentzá and Inga cultures.

    Full Text Available The present paper discusses the amount of water lost by the soil through the transpiration of coffee plants and shade trees in shaded coffee plantation. All methods and techniques employed in the study of transpiration of the shade tree Inga edulis Mart, were exactly the same as those described in a paper recently published (4. It was determined previously (3 that a shaded coffee plant receiving 55% of full sunlight transpired 80% as much as when in 100% full sunlight. The amount of water transpired by a coffee plant was calculated by taking 80% of the amount transpired in unshaded plantation (4. Comparing the water lost by transpiration of shaded coffee plants and shade trees with the average rainfall in Campinas, São Paulo, Brazil, it is seen that from April to September the amount of water transpired exceeds the average rainfall. This finding seems to agree with our previous conclusion (1, 2, 5 that water competition between shade trees and coffee plants is the factor that controls the success of growing coffee under shade in the State of São Paulo, Brazil. The highest daily rate of transpiration encountered, for Inga edvlis was 36.7 milligrams per square decimeter per minute. The average daily transpiration was found to be 9.90 grams per square decimeter per day. The total amount of water transpired by an Inga tree was calculated to be 71,140 liters per plant per year. Since the plants submited to the experiment did not suffer a water shortage at any time, the present results show the approximate amount of water lost by the Inga tree and shaded coffee plant under optimal soil-water conditions.

    Full Text Available ABSTRACT Ecosystems contamination by residues of pesticides requires special attention to the herbicides subject to leaching. The objective was to select tree species to rhizodegradation contaminated by residues of 2,4-D and atrazine and to recompose riparian areas to agricultural fields, then reducing the risk of contamination of water courses. A total of 36 treatments consisted of the combinations of forest species were evaluated [Inga marginata (Inga, Schizolobium parahyba (guapuruvu, Handroanthus serratifolius (ipê amarelo, Jacaranda puberula (carobinha, Cedrela fissilis (cedro, Calophyllum brasiliensis (landin, Psidium mirsinoides (goiabinha, Tibouchina glandulosa (quaresmeira, Caesalpinia férrea (pau-ferro, Caesalpinia pluviosa (sibipiruna, Terminalia argêntea (capitão and Schinopsis brasiliensis (braúna] and three solutions simulating leachate compound (atrazine, 2,4-D and water - control, with four replicates each. The characteristics measured were plant height, stem diameter, number of leaves, leaf area and dry biomass, and foliar nutrition. Forest species survived the herbicide application, and most showed an increase in macronutrients even under an herbicide application, and the Inga had the highest tolerance regarding growth analysis. It is recommended to use species that are more tolerant to Atrazine and 2,4-D in field experiments to confirm previous results of this simulation.

    2016-01-01

    The Indian National Gamma Array (INGA), which has been the principal experimental tool for nuclear structure research in the country for more than one and a half decade, has used digitizer based processing and acquisition in its last campaign at the Pelletron LINAC Facility in Tata Institute of Fundamental Research (TIFR), Mumbai. A series of experiments were performed under this campaign and produced significant physics output. For instance, the use of time stamped data for extracting lifetimes of isomers was an interesting development in this campaign. Based on the experience of using the digitizer based system with INGA at TIFR, a similar system was envisaged for the subsequent campaign of the array scheduled at the Variable Energy Cyclotron Centre (VECC), Kolkata. The trigger logic for the new system was proposed by the Nuclear Physics Group of the UGC-DAE Consortium for Scientific Research (UGC-DAE CSR), Kolkata Centre. The system was developed and manufactured by the XIA LLC, USA. The present work pertains to the testing of the system preceding its intended use in the INGA campaign at VECC

Dr. Karu''s laboratory uses new haptens representing key PAHs to derive recombinant Fab (rFab) and single-chain Fv (scFv) antibodies from hybridoma lines and combinatorial phage display libraries. Computational models of the haptens and combining sites made by Dr. Roberts''s group are used to guide antibody engineering by mutagenesis. Dr. Li''s laboratory develops enzyme immunoassays (EIAs), sensors, and immunoaffinity methods that make use of the novel haptens and antibodies for practical analytical applications in support of DOE''s mission. This report summarizes work completed in one and one-half years of a 3-year project, with close collaboration between the three research groups. Dr. Alexander Karu''s laboratory: the authors proceeded with the two strategies described in the original proposal. Site-directed mutagenesis was used to correct differences in the rFab N-terminal amino acids that were introduced by the degenerate PCR primers used for gene amplification. The binding constants of the rFabs with the corrected sequences will be compared with those of the parent MAbs, and should be very similar. The 4D5 and 10C10 heavy and light chain sequences are being moved to the pCOMB3H phagemid vector to facilitate selection of new engineered mutants.'

    Full Text Available The evaluation of vegetal species germination consents to know its characteristics and permits to understand the factors that influence this process. The aim of this research was to know the germination’s characteristics of some species, such as Eugenia stipitata McVaugh, Inga edulis Mart, Inga spectabilis (Vahl Wild, Piptocoma discolor (Kunth Pruski, Stachytarpheta cayennensis (Rich. Vahl, and Verbena officinalis L., and also their reaction to pregerminative treatments depending on the seed’s diameter. This study was carried out in Pastaza, Province of Pastaza, Ecuador, between February and June, 2014. Different diameters of seeds and pregerminative treatments were used in species, which did not present germination percentages higher than 40%. In the first practice I. edulis and I. spectabilis exceeded this value without treatment. Other species had lower values. Seeds were classified considering two diameters and two doses of gibberellin acid, this was applied to, and evaluated in the E. stipitata. In addition, scarification with sulfuric acid was done. After 45 days of its application, 100 ppm of gibberellic acid with larger seed diameter reported higher percentages of germination in S. cayenennsis, and in E. stipitata, which also interacted with the scarification. V. officinalis and P. discolor, did not present any response to the applications made. I. edulis and I. spectabilis presented high germination percentages without pregerminative treatments, E. stipitata and S. cayenennsis showed response to seed diameter and the applied treatments, while P discolor and V. officinalis did not show any response.

  19. Origin and Domestication of Native Amazonian Crops

    2010-01-01

    Full Text Available Molecular analyses are providing new elements to decipher the origin, domestication and dispersal of native Amazonian crops in an expanding archaeological context. Solid molecular data are available for manioc (Manihot esculenta, cacao (Theobroma cacao, pineapple (Ananas comosus, peach palm (Bactris gasipaes and guaraná (Paullinia cupana, while hot peppers (Capsicum spp., inga (Inga edulis, Brazil nut (Bertholletia excelsa and cupuassu (Theobroma grandiflorum are being studied. Emergent patterns include the relationships among domestication, antiquity (terminal Pleistocene to early Holocene, origin in the periphery, ample pre-Columbian dispersal and clear phylogeographic population structure for manioc, pineapple, peach palm and, perhaps, Capsicum peppers. Cacao represents the special case of an Amazonian species possibly brought into domestication in Mesoamerica, but close scrutiny of molecular data suggests that it may also have some incipiently domesticated populations in Amazonia. Another pattern includes the relationships among species with incipiently domesticated populations or very recently domesticated populations, rapid pre- or post-conquest dispersal and lack of phylogeographic population structure, e.g., Brazil nut, cupuassu and guaraná. These patterns contrast the peripheral origin of most species with domesticated populations with the subsequent concentration of their genetic resources in the center of the basin, along the major white water rivers where high pre-conquest population densities developed. Additional molecular genetic analyses on these and other species will allow better examination of these processes and will enable us to relate them to other historical ecological patterns in Amazonia.

  20. Predictors of leafhopper abundance and richness in a coffee agroecosystem in Chiapas, Mexico.

    Science.gov (United States)

    Burdine, Justin D; Domínguez Martínez, Gabriel H; Philpott, Stacy M

    2014-04-01

    Coffee agroecosystems with a vegetatively complex shade canopy contain high levels of biodiversity. However, as coffee management is intensified, diversity may be lost. Most biodiversity studies in coffee agroecosystems have examined predators and not herbivores, despite their importance as potential coffee pests and coffee disease vectors. We sampled one abundant herbivore group of leafhoppers on an organic coffee farm in Chiapas, Mexico. We sampled leafhoppers with elevated pan traps in high- and moderate-shade coffee during the dry and wet seasons of 2011. The two major objectives were to 1) compare leafhopper abundance and richness during the wet and dry seasons and 2) examine the correlations between habitat characteristics (e.g., vegetation, elevation, and presence of aggressive ants) and leafhopper richness and abundance. We collected 2,351 leafhoppers, representing eight tribes and 64 morphospecies. Leafhopper abundance was higher in the dry season than in the wet season. Likewise, leafhopper richness was higher in the dry season. Several vegetation and other habitat characteristics correlated with abundance and richness of leafhoppers. The number of Inga trees positively correlated with leafhopper abundance, and other significant correlates of abundance included vegetation complexity. Leafhopper richness was correlated with the number of Inga trees. As leafhoppers transmit important coffee diseases, understanding the specific habitat factors correlating with changes in abundance and richness may help predict future disease outbreaks.

  1. Periodic Two-Dimensional GaAs and InGaAs Quantum Rings Grown on GaAs (001) by Droplet Epitaxy.

    Tung, Kar Hoo Patrick; Huang, Jian; Danner, Aaron

    2016-06-01

    Growth of ordered GaAs and InGaAs quantum rings (QRs) in a patterned SiO2 nanohole template by molecular beam epitaxy (MBE) using droplet epitaxy (DE) process is demonstrated. DE is an MBE growth technique used to fabricate quantum nanostructures of high crystal quality by supplying group III and group V elements in separate phases. In this work, ordered QRs grown on an ordered nanohole template are compared to self-assembled QRs grown with the same DE technique without the nanohole template. This study allows us to understand and compare the surface kinetics of Ga and InGa droplets when a template is present. It is found that template-grown GaAs QRs form clustered rings which can be attributed to low mobility of Ga droplets resulting in multiple nucleation sites for QR formation when As is supplied. However, the case of template-grown InGaAs QRs only one ring is formed per nanohole; no clustering is observed. The outer QR diameter is a close match to the nanohole template diameter. This can be attributed to more mobile InGa droplets, which coalesce from an Ostwald ripening to form a single large droplet before As is supplied. Thus, well-patterned InGaAs QRs are demonstrated and the kinetics of their growth are better understood which could potentially lead to improvements in the future devices that require the unique properties of patterned QRs.

    Full Text Available ABSTRACT Little attention has been paid to species of Chamaecrista sect. Apoucouita (Leguminosae-Caesalpinioideae, especially regarding anatomical studies. When only vegetative material is available, the identification of such species may be difficult. Additionally, vegetative material of some species of C. sect. Apoucouita may be even harder to identify because they can resemble species of Inga Mill. (Leguminosae-Mimosoideae. The present study focused on recognizing morphoanatomical characters of leaves that are taxonomically useful for the species of C. sect. Apoucouita by employing standard anatomical techniques. The arrangement of the vascular system in the petiole/rachis, dorsiventral mesophyll, mucilage idioblasts in the epidermis of leaflets and hypostomatic leaves were some of the characters shared by all species studied. Length of the petiole, position and type of extrafloral nectaries, leaflet venation, presence and type of papillae on the epidermis of the leaflet blades and sclereids in the mesophyll were some of the characters useful in the distinction of taxa. The vascular arrangement of the petiole/rachis is a promising character in the distinction of species of C. sect. Apoucouita and Inga. Based on morphoanatomical data, the taxonomic revision of some species and varieties ascribed to C. sect. Apoucouita is suggested.

    Full Text Available The security incidents ion networks are sudden and uncertain, it is very hard to precisely predict the network security situation by traditional methods. In order to improve the prediction accuracy of the network security situation, we build a network security situation prediction model based on Wavelet Neural Network (WNN with optimized parameters by the Improved Niche Genetic Algorithm (INGA. The proposed model adopts WNN which has strong nonlinear ability and fault-tolerance performance. Also, the parameters for WNN are optimized through the adaptive genetic algorithm (GA so that WNN searches more effectively. Considering the problem that the adaptive GA converges slowly and easily turns to the premature problem, we introduce a novel niche technology with a dynamic fuzzy clustering and elimination mechanism to solve the premature convergence of the GA. Our final simulation results show that the proposed INGA-WNN prediction model is more reliable and effective, and it achieves faster convergence-speed and higher prediction accuracy than the Genetic Algorithm-Wavelet Neural Network (GA-WNN, Genetic Algorithm-Back Propagation Neural Network (GA-BPNN and WNN.

    Gamma rays of average energy of 1.25 MeV from radionuclide 60 Co was used in this study and the effects of varying doses 3, 6, 9, 12, 15 kGy on fungal load of and mycotoxin content on sesame seeds were investigated. Sesame seed samples were collected from Abaji, Gwagwalada, Kubwa and Karu markets in Abuja, Federal Capital Territory, Nigeria. A serial dilution technique was employed and the fungi so diluted from the sesame seed samples were identified based on micro and macro morphological characteristics. The Aflatoxin Total and Ochratoxin A Contents in the samples were analysed using AgraQaunt direct combative enzyme-linked immunosorbent assay (ELISA). In all, 157 fungal isolates to four genera: Aspergillus, Curvularia, Penicillium, and Fusarium spp. in decreasing order of predominance were identified. Aspergillus spp. were observed from all the nonirradiated samples. Doses of 6-15kGy eliminated the entire fungal load. Also doses of 9-15kGy generally reduced Ochratoxin A content in all the samples, the rate of mycotoxin reduction was inconsistent with absorbed dose. However, sesame seed samples from the four markets exposed to irradiation dose of 15kGy had the comparatively least Aflatoxin Total content.

    Full Text Available Sementes de espécies do gênero Inga apresentam curta longevidade em condições naturais, freqüentemente inferiores a 15 dias. O teste de germinação para estas sementes tem duração de 7 a 15 dias, tornando-o de difícil aplicabilidade na separação de lotes de sementes a serem beneficiados e armazenados. Assim, esta pesquisa visou verificar a eficiência da utilização do teste de condutividade elétrica na separação, quanto à qualidade fisiológica, de lotes de sementes de ingá (Inga uruguensis Hook. & Arn.. Foram utilizados três lotes de sementes distintos quanto à sua época de coleta, cada qual com dois sublotes em função da forma de obtenção (colheita diretamente nas árvores e coleta sobre o solo. Todos foram armazenados por período de 80 dias, em vermiculita úmida dentro de câmara fria, com análises a cada 20 dias. Os resultados comprovaram a eficiência do teste na separação de lotes de alta (germinação superior a 50%, média (germinação entre 10 e 40% ou baixa (germinação inferior a 10% qualidade fisiológica que corresponderam a valores de condutividade elétrica de, respectivamente, 0-25, 25-60 e acima de 60 mS.g de peso de matéria seca-1.cm-1.Inga seeds have short life under natural conditions, often lower than 15 days. Since, the germination tests for these seeds last 7-15 days, they are inefficient to separate seed lots for processing and storage. This research was carried out to verify the efficacy of the electrical conductivity test to determine the physiological seed quality of I. uruguensis. Fruits were collected at three dates, directly from the trees or from the ground, forming six sublots of different quality. All of them were stored for 80 days in wet vermiculite and in a cold chamber. Seed quality was evaluated every 20 days. The results confirmed the test efficacy to separate of seed lots in three categories: high (more than 50% germination, intermediate (germination between 10 and 40% and

    We investigate the effects of 1.0MeV electron beam irradiation on the photoluminescence of self-assembled InAs/GaAs quantum dots. After irradiation doses up to 1×1016e-/cm2 , photoluminescence of all samples was degraded dramatically and some additional radiation-induced changes in photo-carrier recombination from QDs, which include a slight increase in PL emission with low electron doses under different photo-injection condition in two samples, are also noticed. Different energy shift was observed in two samples with different Quantum Dot sizes. We attribute this remarkable phenomenon to combination of stress relaxation induced red-shift and In-Ga intermixing caused blue-shift.

    In this paper, we report on the phenomenon of nanostructure self-formation on the surface of Cu(In,Ga)Se{sub 2} (CIGS) thin films during inductively coupled argon plasma treatment with its duration varied from 10 to 120 s. The initial films were grown on glass substrates using the selenization technique. During the CIGS film surface treatment in the high-density low-pressure radio-frequency inductively coupled argon plasma there took place a formation of arrays of uniform vertical nanostructures, which shape with increasing processing duration changed from nanocones to nanorods and back to nanocones. A model of the nanotip plasma-assisted self-formation associated with the implementation of micromasking and vapor-liquid-solid mechanisms involving metallic In-Ga (In-Ga-Cu) liquid alloy droplets is proposed.

Lifetimes of six new excited states have been estimated for the first time. To understand the underlying structure of the levels and transition mechanisms, experimental results have been compared with those from the large basis cross-shell shell model calculations. Involvement of orbitals from fp shell and squeezing of the sd-fp shell gap seem to be essential for reliable reproduction of high spin states.

    Neutron deficient isotopes of francium (Z=87, N∼121-123) as excited nuclei were produced in the fusion-evaporation reaction: 197 Au( 16 O, xn) 213-x Fr at 100 MeV. The γ rays from the residues were observed through the high sensitivity Germanium Clover detector array INGA. The decay of the high spin states and the isomeric states of the doubly-odd 208 Fr nuclei, identified from the known sequence of ground state transitions, were observed. The half-lives of the E γ =194(2) keV isomeric transition, known from earlier observations, was measured to be T 1/2 =233(18) ns. A second isomeric transition at E γ =383(2) keV and T 1/2 =33(7) ns was also found. The measured half-lives were compared with the corresponding single particle estimates, based on the level scheme obtained from the experiment.

Polarization measurements of seven gamma rays have been performed for the first time. To understand the underlying structure of the levels and transition mechanisms, experimental data have been compared with the results from large basis cross-shell shell model calculations. The results for the negative parity states are especially important in this respect. Positive parity states indicate an onset of collectivity, whereas the negative parity states are members of ν-π multiplets

    Colloidal synthesis of ternary and quaternary quantum dots (QDs) of In/Ga ratio-varied Cu−In{sub 1−x}−Ga{sub x}−S (CIGS) with nominal x = 0, 0.5, 0.7, and 1 and their application for the fabrication of quantum dot-light-emitting diodes (QLEDs) are reported. Four QLEDs having CIGS QDs with different compositions are all solution-processed in the framework of multilayered structure, where QD emitting layer is sandwiched by hybrid charge transport layers of poly(9-vinlycarbazole) and ZnO nanoparticles. The device performance such as luminance and efficiency is found to be strongly dependent on the composition of CIGS QDs, and well interpreted by the device energy level diagram proposed through the determination of QD valence band minima by photoelectron emission spectroscopic measurement.

    KISS project aims at finding an astrophysical condition for synthesizing r-process heavy element isotopes, which are characterized as the third peak in the solar abundance pattern. This is an experimental challenge in nuclear physics to measure ground and isomeric state properties of unknown nuclei around the region of N=126 isotones. So far we have constructed and developed new type of mass separation system, KISS (KEK Isotope Separation System) and performed measurements of lifetimes and hyperfine structures of some platinum and iridium neutron-rich radioactive isotopes by applying multi-nucleon transfer reactions and in-gas laser ionization and spectroscopy (IGLIS) methods. In this report, recent physics results, updated KISS performance, and future's research plan including a challenge of a systematic mass measurement with MRTOF (Multi-Reflection Time-Of-Flight mass spectrograph) are presented.

    Low-defect density InN films were grown on Si(111) by molecular beam epitaxy over an ∼1 μm thick GaN/AlN buffer/nucleation layer. Electron microscopy observations revealed the presence of inverse polarity domains propagating across the GaN layer and terminating at the sharp GaN/InN (0001 ¯ ) interface, whereas no inversion domains were detected in InN. The systematic annihilation of GaN inversion domains at the GaN/InN interface is explained in terms of indium incorporation on the Ga-terminated inversion domains forming a metal bonded In-Ga bilayer, a structural instability known as the basal inversion domain boundary, during the initial stages of InN growth on GaN

    2018-05-01

    On the example of a few sets of sampling directions in the Brillouin zone, this work shows how important the choice of the cubic harmonics is on the quality of approximation of some quantities by a series of such harmonics. These studies led to the following questions: (1) In the case that for a given l there are several independent harmonics, can one use in the expansion only one harmonic with a given l?; (2) How should harmonics be ordered: according to l or, after writing them in terms of (x4 + y4 + z4)n (x2y2z2)m, according to their degree q = n + m? To enable practical applications of such harmonics, they are constructed in terms of the associated Legendre polynomials up to l = 26. It is shown that electron momentum densities, reconstructed from experimental data for ErGa3 and InGa3, are described much better by harmonics ordered with q.

    This paper studies the utilization of the bromelia specie Tillandsia usneoides L. (Bromeliaceae) for characterization of the particle dispersion at urban and industrial regions. As a case study, a program will be developed for the monitoring the aerosols generated due to action of weather on the solid waste open sky stored and over the waste basin belonging to the INGA, located at Sepetiba bay. The identification of the stable metals will be done by the PIXE technique, and the radionuclides identification by alpha and gamma spectrometry. The preliminary results of aerosol samples collected at Ilha da Madeira region indicate the presence of particles containing Cd, V, K, Ca, Fe, Ti, Zn, Cu, Co and S. The variation in the percentage of each element at the points of collection suggests that there exist more than one aerosol source at the region

    This study presents an band-alignment tailoring of a vertically aligned InAs/GaAs(Sb) quantum dot (QD) structure and the extension of the carrier lifetime therein by rapid thermal annealing (RTA). Arrhenius analysis indicates a larger activation energy and thermal stability that results from the suppression of In-Ga intermixing and preservation of the QD heterostructure in an annealed vertically aligned InAs/GaAsSb QD structure. Power-dependent and time-resolved photoluminescence were utilized to demonstrate the extended carrier lifetime from 4.7 to 9.4 ns and elucidate the mechanisms of the antimony aggregation resulting in a band-alignment tailoring from straddling to staggered gap after the RTA process. The significant extension in the carrier lifetime of the columnar InAs/GaAsSb dot structure make the great potential in improving QD intermediate-band solar cell application.

    The observation of minority-carrier injection-enhanced annealing of radiation-induced defects in InGaP is reported. 1-MeV electron irradiation results demonstrate superior radiation-resistance of InGa 0.5 P 0.5 solar cells compared to GaAs-on-Ge cells. Moreover, minority-carrier injection under forward bias conditions is shown to enhance defect annealing in InGaP and to result in the recovery of InGaP solar cell properties. These results suggest that the radiation-resistance of InGaP-based devices such as InGaP/GaAs(/Ge) multijunction solar cells and InGaP(As) light-emitting devices is further improved under minority-carrier injection condition. copyright 1997 American Institute of Physics

    Full Text Available Assassin bugs (Reduviidae are voracious insects that prey on other arthropods. Recent evidences have pointed out that these predators also feed on plant derived substances in rare opportunities. The present study describes the feeding behavior of the reduviid Atopozelus opsimus on extrafloral nectaries of Inga vera (Fabaceae in a Neotropical savanna area. It was investigated if the insects feed more frequently of extrafloral nectar or prey, and if individuals of different stages of development vary according to feeding behavior. Notably, the results suggest that the diet of all instars and adults consist mainly of extrafloral nectar (N = 1013, in detriment of captured prey ingestion (N = 18. Also, there was no variation on feeding behavior and life stage.

    The high-spin states in 153Ho have been studied by the La57(20Ne139,6 n ) reaction at a projectile energy of 139 MeV at the Variable Energy Cyclotron Centre (VECC), Kolkata, India, utilizing an earlier campaign of the Indian National Gamma Array (INGA) setup. Data from γ -γ coincidence, directional correlation, and polarization measurements have been analyzed to assign and confirm the spins and parities of the levels. We have suggested a few additions and revisions of the reported level scheme of 153Ho. The RF-γ time difference spectra have been useful to confirm the half-life of an isomer in this nucleus. From the comparison of experimental and theoretical results, it is found that there are definite indications of shape coexistence in this nucleus. The experimental and calculated lifetimes of several isomers have been compared to follow the coexistence and evolution of shape with increasing spin.

    2012-01-01

    The properties of InGaN alloys are important for many applications in optoelectronics, since their fundamental gap spans the visible range. Calculating properties, particularly for InN, is theoretically challenging, especially to obtain accurate values for the band gap. We have developed a semi-empirical parametrisation of (In,Ga) N using the density functional based tight binding method (DFTB), where the band gaps of InN and GaN have been empirically corrected to experiment. We demonstrate the performance of this method by calculating a range of properties for the two materials, including elastic constants and carrier effective masses. There are several methods to model alloys of these material, one of the simplest being the virtual crystal approximation, which we apply to derive electronic properties over the whole composition range for InGaN.

  16. Effects of Sb-doping on the grain growth of Cu(In, Ga)Se2 thin films fabricated by means of single-target sputtering

    To investigate the effects of Sb doping on the kinetics of grain growth in Cu(In,Ga)Se 2 (CIGS) thin films during annealing, CIGS thin films were sputtered onto Mo coated substrates from a single CIGS alloy target, followed by chemical bath deposition of Sb 2 S 3 thin layers on top of CIGS layers and subsequent annealing at different temperatures for 30 min in Se vapors. X-ray diffraction results showed that CIGS thin films were obtained directly using the single-target sputtering method. After annealing, the In/Ga ratio in Sb-doped CIGS thin films remained stable compared to undoped film, possibly because Sb can promote the incorporation of Ga into CIGS. The grain growth in CIGS thin films was enhanced after Sb doping, exhibiting significantly larger grains after annealing at 400 °C or 450 °C compared to films without Sb. In particular, the effect was strikingly significant in grain growth across the film thickness, resulting in columnar grain structure in Sb-doped films. This grain growth improvement may be led by the diffusion of Sb from the front surface to the CIGS-Mo back interface, which promoted the mass transport process in CIGS thin films. - Highlights: ► Cu(In,Ga)Se 2 (CIGS) thin films made by sputtering from a single CIGS target. ► Chemical bath deposition used to introduce antimony into CIGS absorber layers. ► In/Ga ratio decreases in Sb-doped annealed films, comparatively to undoped films. ► Sb-doped CIGS films are superior to undoped films in terms of grain-growth kinetics

  17. Soil aggregation and organic carbon of Oxisols under coffee in agroforestry systems

    Full Text Available Intensive land use can lead to a loss of soil physical quality with negative impacts on soil aggregates, resistance to root penetration, porosity, and bulk density. Organic and agroforestry management systems can represent sustainable, well-balanced alternatives in the agroecosystem for promoting a greater input of organic matter than the conventional system. Based on the hypothesis that an increased input of organic matter improves soil physical quality, this study aimed to evaluate the impact of coffee production systems on soil physical properties in two Red-Yellow Oxisols (Latossolos Vermelho-Amarelos in the region of Caparaó, Espirito Santo, Brazil. On Farm 1, we evaluated the following systems: primary forest (Pf1, organic coffee (Org1 and conventional coffee (Con1. On Farm 2, we evaluated: secondary forest (Sf2, organic coffee intercropped with inga (Org/In2, organic coffee intercropped with leucaena and inga (Org/In/Le2, organic coffee intercropped with cedar (Org/Ced2 and unshaded conventional coffee (Con2. Soil samples were collected under the tree canopy from the 0-10, 10-20 and 20-40 cm soil layers. Under organic and agroforestry coffee management, soil aggregation was higher than under conventional coffee. In the agroforestry system, the degree of soil flocculation was 24 % higher, soil moisture was 80 % higher, and soil resistance to penetration was lower than in soil under conventional coffee management. The macroaggregates in the organic systems, Org/In2, Org/In/Le2, and Org/Ced2 contained, on average, 29.1, 40.1 and 34.7 g kg-1 organic carbon, respectively. These levels are higher than those found in the unshaded conventional system (Con2, with 20.2 g kg-1.

    Coal mining-related activities result in a degraded landscape and sites associated with large amounts of dumped waste material. The arid soil resulting from acid mine drainage affects terrestrial and aquatic ecosystems, and thus, site remediation programs must be implemented to mitigate this sequential deleterious processes. A low-cost alternative material to counterbalance the affected physico-chemical-microbiological aspects of the degraded soil is the amendment with low contaminated and stabilized industrial organic sludge. The content of nutrients P and N, together with stabilized organic matter, makes this material an excellent fertilizer and soil conditioner, fostering biota colonization and succession in the degraded site. However, choice of native plant species to restore a degraded site must be guided by some minimal criteria, such as plant survival/adaptation and plant biomass productivity. Thus, in this 3-month study under environmental conditions, phytoproductivity tests with five native plant species (Surinam cherry Eugenia uniflora L., C. myrianthum-Citharexylum myrianthum, Inga-Inga spp., Brazilian peppertree Schinus terebinthifolius, and Sour cherry Prunus cerasus) were performed to assess these criteria, and additional biochemical parameters were measured in plant tissues (i.e., protein content and peroxidase activity) exposed to different soil/sludge mixture proportions. The results show that three native plants were more adequate to restore vegetation on degraded sites: Surinam cherry, C. myrianthum, and Brazilian peppertree. Thus, this study demonstrates that phytoproductivity tests associated with biochemical endpoint measurements can help in the choice of native plant species, as well as aiding in the choice of the most appropriate soil/stabilized sludge proportion in order to optimize biomass production.

  19. SERIANTHES Benth. (Leguminosae-Mimosoideae-Ingeae

    2015-10-01

    Full Text Available The genus Serianthes was erected by Bentham to accomodate plants which Wallich had called Inga grandiflora, from Singapore, and those which Bertero had called Acacia myriadenia, from Tahiti. It has been accepted from the first, as it is amply distinct from Acacia and reasonably so from Inga. though it is usually placed in the tribe Ingeae. Serianthes is widespread in the southwest Pacific, usually, though not always, occurring on islands, frequently on calcareous or serpentine rocks or their derived soils. It is seldom abundant, though in places common. In habit it varies from a dwarf tree or large shrub to a forest giant. It is reported to be an excellent timber tree, but seems nowhere to be abundant enough to be important commercially. Since Bentham's original description in 1844, eleven additional species and one variety have been ascribed to it in addition to the original S. grandiflora. Three of these do not belong in Serianthes. Most of the specimens in herbaria, excepting those called S. grandiflora, have been misidentified, usually being placed in S. myriadenia. Although I first saw this genus growing and collected it in Raivavae and Rurutu in 1934, my interest in it was aroused by failure, in 1950, to find a satisfactory disposition for specimens collected in Palau, similar to those that Kanehira had referred to S. grandiflora, which they clearly were not. The more I tried to make sense of the herbarium material available in a number of herbaria the more frustrating the problem became. Notes were accumulated in a most haphazard and unsystematic manner, as I had no intention of doing more than identifying my Micronesian material. Finallyit became evident that over half of the entities discernible in the material examined were undescribed, and I felt a certain obligation to work up at least a synopsis of the genus.

    Full Text Available Parakeets usually forage for massive and ephemeral plant resources at forest canopies. Fruit pulp is widely cited as a major food resource for these birds, which often eat seeds and nectar. In this study, I assessed flower and fruit production at a gallery forest in the Pantanal flood plain (Brazil in order to evaluate the relationship between food resource production and abundance of a common parakeet, Brotogeris chiriri. Also, I evaluated the relationship between food resource production and foraging activity. Parakeet abundance varied markedly along the year, coinciding with massive episodes of flower and fleshy fruit availability. Inga vera nectar, intensely used during the latter part of dry season, was by far the most exploited food item by parakeets when they were very abundant. The nectar comprised 34% of the parakeets' diet (N = 131 feeding records at the gallery forest, while fleshy fruits made up the rest. Parakeets principally exploited fruits of Cecropia pachystachya and Ficus luschnathiana, besides palm fruits and Inga vera arils. The consistent relationship between foraging activity and parakeet abundance, as well as the coincidence between fluctuations of these parameters and availability of major food resources, suggests that food availability mostly influenced B. chiriri occurrence in the gallery forest. Furthermore, I found no evidence for gallery forest use for roosting and/or breeding, in spite of the fact that such factors usually influence local parakeet abundance.Periquitos normalmente exploram recursos massivos e efêmeros no dossel das florestas tropicais.

    The new cluster compound K{sub 3}Ga{sub 11-x}In{sub x}, which exhibits a very small In/Ga phase width of x = 1.16 to 1.36 only, was obtained in the course of a systematic synthetic, crystallographic and bond theoretical investigation of mixed potassium trielides of the ternary system K-In-Ga. The compound, which was synthesized from nearly stoichiometric amounts of the elements at a maximum temperature of 500 C, crystallizes in a new orthorhombic crystal structure type [space group Cmmm, a = 1577.9(5), b = 3355.1(8), c = 655.2(2) pm, Z = 10, R{sub 1} = 0.0471]. In the complex polyanion, the triels form two crystallographically different [Ga{sub 12}] icosahedra, which are present in a 1:2 ratio, and a previously unknown [M{sub 13}] ''double-cluster'' consisting of two vertex-sharing [M{sub 7}] pentagonal bipyramids. All clusters are connected among each other and via a four-bonded pure In and Ga atom [In(1), Ga(1)]. The polyanion of the compound with the overall formula K{sub 15}M{sub 55} can thus be split up according to [Ga(1X){sub 12}][Ga(2X){sub 12}]{sub 2}[M(3X){sub 13}]In(1){sub 4}Ga(1){sub 2}. Herein, the all-exo bonded closo icosahedra carry a charge of -2, the six four-bonded In/Ga contribute with a charge of -6 and the new [M{sub 13}] ''double-cluster'' thus carries a charge of -3. Under the reasonable assumption of an ''intermediate'' interaction between the two cluster fragments, this charge, i.e. the presence of 15 skeleton electron pairs, is in accordance with the mno electron counting rules. FP-LAPW DFT band structure calculations of two ordered model compounds support this interpretation: The tDOS exhibits a small bandgap and the electron density map suggests a limited additional interaction between the Ga{sub 5} bases of the two bipyramidal cluster fragments.

    Full Text Available O objetivo deste trabalho foi avaliar o crescimento inicial da parte aérea e do sistema radicular, a nutrição mineral e a fixação biológica de N2 (FBN em plantios consorciados de Eucalyptus grandis e leguminosas arbóreas. O delineamento experimental foi o de blocos ao acaso com três repetições e sete tratamentos por bloco. Nas linhas de plantio, entre as plantas de E. grandis, foram plantadas, intercaladamente, leguminosas arbóreas nativas de matas brasileiras - Peltophorum dubium, Inga sp., Mimosa scabrella, Acacia polyphylla, Mimosa caesalpiniaefolia - e uma leguminosa exótica, Acacia mangium. Realizou-se, também, o plantio puro de E. grandis. Mimosa scabrella e A. mangium foram as leguminosas com maior crescimento. Eucalyptus grandis consorciado com M. scabrella cresceu menos, no entanto foi o povoamento com maior acumulação de biomassa. As densidades de raízes finas (DRF do E. grandis foram 6 a 20 vezes maiores que as DRF das leguminosas na camada superficial do solo (0-10 cm 24 meses após plantio. A DRF de M. scabrella e de M. caesalpiniaefolia foi maior na camada 30-50 cm e menor na camada 10-30 cm. Os valores de delta15N da M. scabrella indicam que 90% do N acumulado em seus tecidos é oriundo da FBN.The objective of this work was to assess interactions between species on the above and belowground growth, nitrogen uptake and biological nitrogen fixation (BNF in mixed stands of Eucalyptus grandis and native leguminous N2-fixing trees. A complete randomized block design was installed with seven treatments and three blocks. Within the lines of the E. grandis seedlings, native leguminous N2-fixing trees - Peltophorum dubium, Inga sp., Mimosa scabrella, Acacia polyphylla, Mimosa caesalpiniaefolia - and one exotic leguminous plant, Acacia mangium, were intercropped. E. grandis was also solely planted. Mimosa scabrella and A. mangium were the legume trees that presented the highest growth. Although E. grandis showed a lower

    The effects of Na atoms on high pressure structural phase transitions of CuIn 0.5 Ga 0.5 Se 2 (CIGS) were studied by an ab initio method using density functional theory. At ambient pressure, CIGS is known to have chalcopyrite (I 4-bar 2 d) structure. The high pressure phase transitions of CIGS were proposed to be the same as the order in the CuInSe 2 phase transitions which are I 4-bar 2 d→F m 3-bar m→C m c m structures. By using the mixture atoms method, the Na concentration in CIGS was studied at 0.1, 1.0 and 6.25%. The positive mixing enthalpy of Na at In/Ga sites (Na InGa ) is higher than that of Na at Cu sites (Na Cu ). It confirmed previous studies that Na preferably substitutes on the Cu sites more than the (In, Ga) sites. From the energy-volume curves, we found that the effect of the Na substitutes is to reduce the hardness of CIGS under high pressure. The most significant effects occur at 6.25% Na. We also found that the electronic density of states of CIGS near the valence band maximum is increased noticeably in the chalcopyrite phase. The band gap is close in the cubic and orthorhombic phases. Also, the Na Cu -Se bond length in the chalcopyrite phase is significantly reduced at 6.25% Na, compared with the pure Cu-Se bond length. Consequently, the energy band gap in this phase is wider than in pure CIGS, and the gap increased at the rate of 31 meV GPa -1 under pressure. The Na has a small effect on the transition pressure. The path of transformation from the cubic to orthorhombic phase was derived. The Cu-Se plane in the cubic phase displaced relatively parallel to the (In, Ga)-Se plane by 18% in order to transform to the Cmcm phase. The enthalpy barrier is 0.020 eV/atom, which is equivalent to a thermal energy of 248 K. We predicted that F m 3-bar m and Cmcm can coexist in some pressure range. (paper)

    Mosquito-borne dengue virus (DENV) is maintained in a sylvatic, enzootic cycle of transmission between canopy-dwelling non-human primates and Aedes mosquitoes in Borneo. Sylvatic DENV can spill over into humans living in proximity to forest foci of transmission, in some cases resulting in severe dengue disease. The most likely vectors of such spillover (bridge vectors) in Borneo are Ae. albopictus and Ae. niveus. Borneo is currently experiencing extensive forest clearance. To gauge the effect of this change in forest cover on the likelihood of sylvatic DENV spillover, it is first necessary to characterize the distribution of bridge vectors in different land cover types. In the current study, we hypothesized that Ae. niveus and Ae. albopictus would show significantly different distributions in different land cover types; specifically, we predicted that Ae. niveus would be most abundant in forests whereas Ae. albopictus would have a more even distribution in the landscape. Mosquitoes were collected from a total of 15 sites using gravid traps and a backpack aspirator around Kampong Puruh Karu, Sarawak, Malaysian Borneo, where sylvatic DENV spillover has been documented. A total of 2447 mosquitoes comprising 10 genera and 4 species of Aedes, were collected over the three years, 2013, 2014 and 2016, in the three major land cover types in the area, homestead, agriculture and forest. Mosquitoes were identified morphologically, pooled by species and gender, homogenized, and subject to DNA barcoding of each Aedes species and to arbovirus screening. As predicted, Ae. niveus was found almost exclusively in forests whereas Ae. albopictus was collected in all land cover types. Aedes albopictus was significantly (P = 0.04) more abundant in agricultural fields than forests. Sylvatic DENV was not detected in any Aedes mosquito pools, however genomes of 14 viruses were detected using next generation sequencing. Land cover type affects the abundance and distribution of the most

    The GRAMUS pump is a gas-recovery and minimal usage mechanism designed to recover waste gases, thereby reducing emission to the atmosphere. The pump, invented by Dan Vezina in Fort St. John, requires no oil to lubricate it, is virtually maintenance-free and low enough in price to rapidly recover its cost when used to replace old style diaphragm pumps which are widely use in the petroleum industry for venting gas to the atmosphere. The GRAMUS pump recovers the drive gas, and rather than venting it into the atmosphere it injects it back into the system through its double-acting cylinder which pumps without the need for oil around its switching mechanism. The prototype was tested by Talisman Energy at their Inga Lake location, and found that the GRAMUS recovery system saved them $840 per month in propane costs (the gas that is commonly used to power the old style diaphragm pumps). The pumps are now manufactured and distributed commercially by Crown West Steel Fabricators in Kelowna, BC (in partnership with Vezina). They are doing brisk business with virtually every company in BC and Alberta whose operations formerly used the old diaphragm pumps

Köttprover från naturbetande renar (n=4; 2 härkar och 2 vajor från Seward Peninsula inkluderades i studien för att representera kvaliteten på traditionellt producerat renkött från Alaska. Inga signifikanta skillnader i tillväxt observerades, varken mellan SBM- och WFM-grupperna eller mellan härkar och vajor. Foderutnyttjandet var dock signifikant bättre hos WFM-renarna. Slaktutbytet var högst för renarna i SBM-gruppen, däremot rapporterades inga skillnader i levandevikt, slaktkroppsegenskaper, pH-värde och temperatur i ytterfilén, skärmotstånd, färg eller vattenhållande förmåga i köttet när de tre grupperna av renar jämfördes (SBM, WFM och naturbetande djur. Köttet från de naturbetande renarna hade det signifikant högsta innehållet av både omega-3-fettsyror och av fleromättade fettsyror. Kött från SBM-renarna hade det högsta innehållet av triglycerider och det lägsta innehållet av fosfolipider jämfört med de andra två grupperna. Den tränade smakpanelen kunde inte hitta några skillnader i sensoriska egenskaper hos köttet från renarna i de tre olika grupperna. I en konsumentundersökning rapporterades kommentarer om olika ”vilt-relaterade” bismaker i kött från naturbetande renar (24% av konsumenterna och från WFM-gruppen (15% av konsumenterna, men inga ”fisk-liknande” bismaker i köttet kunde påvisas.

    Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks of Fabaceae trees (Inga edulis, Schizolobium amazonicum and Dipteryx odorata) subjected to fertilization treatments (T1 - no fertilization; T2 - chemical; T3 - organic; and T4 - organic and chemical fertilization) in a degraded area of the Balbina Hydroelectric Dam, AM - Brazil. As an early successional species, I. edulis stocked more C and nutrients than the other two species independent of the fertilization treatment, and S. amazonicum stocked more C than D. odorata under T1 and T4. The mixed species plantation had the potential to stock 4.1 Mg C ha-1 year-1, while I. edulis alone could stock 9.4 Mg C ha-1 year-1. Mixing species that rapidly assimilate C and are of significant ecological and commercial value (e.g., Fabaceae trees) represents a good way to restore degraded areas. Our results suggest that the tested species be used for forest restoration in Amazonia.

The {gamma} rays from the residues were observed through the high sensitivity Germanium Clover detector array INGA. The decay of the high spin states and the isomeric states of the doubly-odd {sup 208}Fr nuclei, identified from the known sequence of ground state transitions, were observed. The half-lives of the E{sub {gamma}=}194(2) keV isomeric transition, known from earlier observations, was measured to be T{sub 1/2}=233(18) ns. A second isomeric transition at E{sub {gamma}=}383(2) keV and T{sub 1/2}=33(7) ns was also found. The measured half-lives were compared with the corresponding single particle estimates, based on the level scheme obtained from the experiment.

    The first observation of the prompt and the delayed γ transitions involving the high spin states in 210 Fr is reported. The decay of the high spin states and the isomeric levels of 210 Fr, identified for the first time from the known sequence of low-lying transitions found earlier in the α decay of 214 Ac, were studied. High spin states of the doubly-odd 210 Fr, which were produced by the fusion evaporation reaction 197 Au ( 16 O, xn) 213-x Fr, were populated and the subsequent emitted γ rays were detected through the high-sensitivity germanium clover detector array INGA. The level scheme up to yrast levels of 5.3 MeV excitation energy and ∼20(ℎ/2π) angular momentum could be established for the first time through γγ, γγΔT coincidence, and DCO ratio measurements. A new low-lying isomeric transition at E γ = 203(2) keV was observed. The half-life was measured to be T 1/2 = 41(2) ns. The measured half-life was compared with the corresponding single-particle estimate, based on the level scheme obtained from the experiment.

    High spin states in Bismuth and Thallium nuclei near the Z = 82 shell closure and Cesium nuclei near the N = 82 shell closure in A = 190 and A = 130 regions, respectively, have been experimentally investigated using heavy-ion fusion evaporation reaction and by detecting the gamma rays using the Indian National Gamma Array (INGA). Interesting shape properties in these transitional nuclei have been observed. The results were compared with the neighboring nuclei in these two regions. The total Routhian surface (TRS) calculations have been performed for a better understanding of the observed properties. In mass region A = 190, a change in shape from spherical to deformed has been observd around neutron number N = 112 for the Bi (Z = 83) isotopes with proton number above the magic gap Z = 82, whereas, the shape of Tl (Z = 81) isotopes with proton number below the magic gap Z = 82 remains stable as a function of neutron number. An important transition from aplanar to planar configuration of angular momentum vectors leading to the occurance of nuclar chirality and magnetic rotation, respectively, has been proposed for the unique parity πh{sub 11/2}⊗νh{sub 11/2} configuration in Cs isotopes in the mass region A ∼ 130 around neutron number N = 79. These results are in commensurate with the TRS calculations.

    Plant-based preparations are extensively used in Surinamese folk medicine for treating leishmaniasis, but often without a scientific rationale. To evaluate 25 Surinamese medicinal plants for their potential efficacy against leishmaniasis. Concentrated plant extracts were evaluated for their effect on the viability of L. (V.) guyanensis AMC, L. (L.) major NADIM5, and L. (L.) donovani GEDII promastigotes, as well as intracellular amastigotes of L. (L.) donovani BHU814 in infected THP-1 cells. Selectivity was assessed by cytotoxicity against THP-1 cells. The only plant extract that showed potentially meaningful anti-leishmanial activity was that from Solanum lycocarpum that displayed mean IC50 values of about 51, 61, and 500 µg/mL against THP-1 cells. The Bryophyllum pinnatum, Inga alba, and Quassia amara extracts displayed moderate to high IC50 values against promastigotes (about 51 to >500 µg/mL) and/or amastigotes (about 224 to >500 µg/mL) but were relatively toxic to THP-1 cells (IC50 values plant extracts exhibited in many cases IC50 values close to, around, or above 500µg/mL against promastigotes, amastigotes, and THP-1 cells. The S. lycocarpum preparation may be useful against leishmaniasis and may have a good safety index, warranting further investigations into its active constituents and mechanism(s) of action.

    Full Text Available Introduction Schistosomiasis is a parasitic disease of public health concern in Brazil, and the construction of hydroelectric dams, in addition to increasing permanent human settlement and tourism, has created conditions suitable for the establishment of mollusks that can transmit schistosomiasis. Such areas require a number of actions to prevent the establishment of schistosomiasis. This paper reports on a freshwater malacological survey carried out in the geographical area of the Manso Power Plant. Methods Mollusks were collected in 18 municipalities in the State of Mato Grosso between February 2002 and February 2004 (qualitative study and from April 2009 to February 2011 (quantitative study. Results Thirty-one species of mollusks were collected, including newly recorded species (Antillorbis nordestensis and Burnupia ingae. In addition, the geographic distributions of known species, including Biomphalaria straminea, a snail vector of Schistosoma mansoni, were expanded. A total of 4,507 specimens were collected in the APM Manso reservoir (Usina Hidrelétrica de Aproveitamento Múltiplo de Manso during the quantitative study, and Biomphalaria amazonica was found in six of the 10 localities analyzed. The Afroasiatic species Melanoides tuberculata, introduced after February 2009, was the dominant species (relative abundance 94.96%. Conclusions The study area is epidemiologically important due to the occurrence of B. straminea and B. amazonica, which are vectors of schistosomiasis, and M. tuberculata, a snail host of Centrocestus formosanus, which is responsible for centrocestiasis transmission. Observations of M. tuberculata and the exotic freshwater clams Corbicula fluminea and Corbicula largillierti raise concerns about biodiversity.

    The practical realization of epitaxial quantum dot (QD) nanocrystals led before long to impressive experimental advances in optoelectronic devices, as well as to the emergence of new technological fields. However, the necessary capping process is well-known to hinder a precise control of the QD morphology and therefore of the possible electronic structure required for certain applications. A straightforward approach is shown to tune the structural and optical properties of InAs/GaAs QDs without the need for any capping material different from GaAs or annealing process. The mere adjust of the capping rate allows controlling kinetically the QD dissolution process induced by the surface In-Ga intermixing taking place during overgrowth, determining the final metastable structure. While low capping rates make QDs evolve into more thermodynamically favorable quantum ring structures, increasing capping rates help preserve the QD height and shape, simultaneously improving the luminescence properties. Indeed, a linear relationship between capping rate and QD height is found, resulting in a complete preservation of the original QD geometry for rates above ∼2.0 ML s-1. In addition, the inhibition of In diffusion from the QDs top to the areas in between them yields thinner WLs, what could improve the performance of several QD-based optoelectronic devices.

    Evaluation of the chemical behavior of zinc and cadmium as well as the influence of biological activity in the sorption kinetics under microcosm experiments by mangrove sediments collected in Sepetiba Bay - Rio de Janeiro was carried out. The mentioned area was well contaminated due to the leaching from the tailing pile by the abandoned zinc processing company Inga Mercantil. Radiotracer 65 Zn and 109 Cd were used to follow their exchange across water-sediment interfaces up to 48 hours experiments in six mangrove sediment cores. To determine the benthic activity index (BAI) the cores were treated with formaldehyde (biocide) and it was found that the presence of the radiotracers in the deeper layers of sediment without formaldehyde treatment showed clearly the influence of benthic activity retention (benthic faunal and microbial effects), since the same pattern was not found in the treated sediment. The activity values obtained for 65 Zn and 109 Cd in the untreated sediment with formaldehyde on the first centimeter were 53.79±0.28 % and 67.34±0.16 % respectively, whereas for the treated ones, were 98.72 ± 0.29 % and 98.31 ± 0.24 % respectively. Thus, it was demonstrated that the use of formaldehyde, as biological activity inhibitor, ceases the bioturbation process and allowed the accumulation along the sediment. (author)

In search of a new understanding of East Asian history]. Seoul: Nŏmŏ puksŭ, 2015. ISBN: 9788994606392. The Eurocentrism and modern-centrism that have established themselves as the predominant discourses of historians may need to be further pushed aside by new discourses. Sinocentrism, decentralism, multiple modernities, alternative modernity—these are just a few of the candidates. No one knows what the dominant discourse is going to be down the road. Fourteen authors, including editors Miyazima Hiroshi and Bae Hang-seob, contributed to the collection What Time Is East Asia? In Search of a New Understanding of East Asian History in 2015. This book presents a new historical discourse that emerged in Korea as a critique of Eurocentrism and modern-centrism. The title refers to a question posed by Alexander Woodside in his 2006 book, Lost Modernities, and is meant to suggest that the historical experience of East Asia cannot be grasped by historical perspectives based on Eurocentrism...

    Sepiolite clay mineral was used as a support for the immobilisation of the peroxidase enzyme from ingá-cipó (Inga edulis Mart.) and was used with graphite powder, multi-walled carbon nanotubes (CNTs), mineral oil, and nafion 0.5% (v/v) in the development of a new biosensor for the determination of the antioxidant tert-butylhydroquinone (TBHQ) by square-wave voltammetry (SWV). For the optimisation and application of the biosensor, several parameters were investigated to determine the optimum experimental conditions using SWV. The best performance was obtained using a 0.1 mol L(-1) phosphate buffer solution (pH 7.0), 4.0 × 10(-4) mol L(-1) hydrogen peroxide, a frequency of 50 Hz, a pulse amplitude of 60 mV, and a scan increment of 6 mV. The biosensor showed good repeatability and reproducibility and remained stable for a period of 20 weeks. The analytical curve revealed a linear response range of 1.65 to 9.82 mg L(-1) (r = 0.994) with detection and quantification limits of 0.41 and 1.25 mg L(-1). A recovery study of TBHQ in salad dressing samples yielded values from 99.6-104.8%. The proposed biosensor was successfully used for the determination of TBHQ in commercial salad dressing samples, giving a relative error of 5.4% in relation to the comparative method (chromatographic).

    Given the increase of people with gastrointestinal disorders, the search for alternative treatments with fewer side effects is vital, as well as the demand for food or plants that can help protect the stomach. The aim of this study was to evaluate the gastroprotective action of the extracts of wild fruit trees of Myrcianthes pungens (guabiju); Inga vera Willd. (ingá-banana) and Marlierea tomentosa Cambess. (guarapuruna) in in vivo pharmacological models. The different parts of the fruits were separately subjected to a process of extraction by methanol. Two experimental pharmacological models were conducted in mice; the gastric ulcer model induced by non-steroidal anti-inflammatory (indomethacin), and the gastric ulcer model induced by ethanol/HCl, which allowed us to evaluate the gastroprotective activity of the extracts at a dose of 250 mg/kg. Subsequently, the total lesion area (mm2) and relative lesion area (%) were determined. The results showed significant gastroprotective activity against the aggressive agents used - ethanol and indomethacin - for all the extracts tested. It is assumed that the fruits have bioactive compounds such as antioxidant substances that act on the prostaglandin levels, protecting them from the damage caused by ethanol and indomethacin. These results prompt further studies to isolate and identify the active properties.

    Bananas (Musa spp.) belong to the most important global food commodities, and their cultivation represents the world's largest monoculture. Although the plant-associated microbiome has substantial influence on plant growth and health, there is a lack of knowledge of the banana microbiome and its influencing factors. We studied the impact of (i) biogeography, and (ii) agroforestry on the banana-associated gammaproteobacterial microbiome analyzing plants grown in smallholder farms in Nicaragua and Costa Rica. Profiles of 16S rRNA genes revealed high abundances of Pseudomonadales, Enterobacteriales, Xanthomonadales, and Legionellales. An extraordinary high diversity of the gammaproteobacterial microbiota was observed within the endophytic microenvironments (endorhiza and pseudostem), which was similar in both countries. Enterobacteria were identified as dominant group of above-ground plant parts (pseudostem and leaves). Neither biogeography nor agroforestry showed a statistically significant impact on the gammaproteobacterial banana microbiome in general. However, indicator species for each microenvironment and country, as well as for plants grown in Coffea intercropping systems with and without agri-silvicultural production of different Fabaceae trees (Inga spp. in Nicaragua and Erythrina poeppigiana in Costa Rica) could be identified. For example, banana plants grown in agroforestry systems were characterized by an increase of potential plant-beneficial bacteria, like Pseudomonas and Stenotrophomonas, and on the other side by a decrease of Erwinia. Hence, this study could show that as a result of legume-based agroforestry the indigenous banana-associated gammaproteobacterial community noticeably shifted.

However, combinatory antioxidant/anti-proliferative effect was only detected in Oenocarpus bataua Mart., Arecaceae (DPPH = 903.8 and ORAC = 1024 µg TE/mg extract; IC50 for Hep-G2 and HT-29 at 102.6 and 38.8 µg/ml, respectively and Inga edulis Mart., Fabaceae (DPPH = 337.0 and ORAC = 795.7 µg TE/mg extract; IC50 for Hep-G2 and HT-29 at 36.3 and 57.9 µg/ml, respectively. Phenolic content was positively correlated with antioxidant potential, however not with anti-proliferative effect. None of these extracts possessed toxicity towards normal foetal lung cells, suggesting their possible use in development of novel plant-based agents with preventive and/or therapeutic action against oxidative stress-related diseases.

    CIGS based solar cells are among the most promising thin-film techniques for cheap, yet efficient modules. They have been investigated for many years, but the full potential of CIGS cells has not yet been exhausted and many effects are not understood. For instance, the band gap of the absorber material Cu(In,Ga)Se{sub 2} varies with Ga content. The question why solar cells with high Ga content have low efficiencies, despite the fact that the band gap should have the optimum value, is still unanswered. We are using Monte Carlo simulations in combination with a cluster expansion to investigate the homogeneity of the In-Ga distribution as a possible cause of the low efficiency of cells with high Ga content. The cluster expansion is created by a fit to ab initio electronic structure energies. The results we found are crucial for the processing of solar cells, shed light on structural properties and give hints on how to significantly improve solar cell performance. Above the transition temperature from the separated to the mixed phase, we observe different sizes of the In and Ga domains for a given temperature. The In domains in the Ga-rich compound are smaller and less abundant than the Ga domains in the In-rich compound. This translates into the Ga-rich material being less homogeneous.

    The in-gas laser ionization and spectroscopy (IGLIS) technique is used to produce and to investigate short-lived radioactive isotopes at on-line ion beam facilities. In this technique, the nuclear reaction products recoiling out of a thin target are thermalized and neutralized in a high-pressure noble gas, resonantly ionized by the laser beams in a two-step process, and then extracted from the ion source to be finally accelerated and mass separated. Resonant ionization of radioactive species in the supersonic gas jet ensures very high spectral resolution because of essential reduction of broadening mechanisms. To obtain the maximum efficiency and the best spectral resolution, properties of the supersonic jet and the laser beams must be optimized. To perform these studies a new off-line IGLIS laboratory, including a new high-repetition-rate laser system and a dedicated off-line mass separator, has been commissioned. In this article, the specifications of the different components necessary to achieve optimum conditions in laser-spectroscopy studies of radioactive beams using IGLIS are discussed and the results of simulations are presented.

    High resolution synchrotron radiation core level photoemission measurements have been used to study the high temperature stability of sulphur passivated InGaAs surfaces and comparisons made with atomically clean surfaces subjected to the same annealing temperatures. Sulphur passivation of clean InGaAs surfaces prepared by the thermal removal of an arsenic capping layer was carried out using an in situ molecular sulphur treatment in ultra high vacuum. The elemental composition of the surfaces of these materials was measured at a series of annealing temperatures up to 530 C. Following a 480 C anneal In:Ga ratio was found to have dropped by 33% on sulphur passivated surface indicating a significant loss of indium, while no drop in indium signal was recorded at this temperature on the atomically InGaAs surface. No significant change in the As surface concentration was measured at this temperature. These results reflect the reduced thermal stability of the sulphur passivated InGaAs compared to the atomically clean surface which has implications for device fabrication.

    Direct measurements on the growth of InAs quantum dots (QDs) and various cap layers during molecular beam epitaxy are performed by in situ X-ray diffraction (XRD). The evolution of strain induced both in the QDs and cap layers during capping is discussed based on the XRD intensity transients obtained at various lattice constants. Transients with different features are observed from those obtained during InGaAs and GaAs capping. The difference observed is attributed to In-Ga intermixing between the QDs and the cap layer under limited supply of In. Photoluminescence (PL) wavelength can be tuned by controlling the intermixing, which affects both the strain induced in the QDs and the barrier heights. The PL wavelength also varies with the cap layer thickness. A large redshift occurs by reducing the cap thickness. The in situ XRD observation reveals that this is a result of reduced strain. We demonstrate how such information about strain can be applied for designing and preparing novel device structures

    We studied the impact of H 2 pressure during post-metallization annealing on the chemical composition of a HfO 2 /Al 2 O 3 gate stack on a HCl wet-cleaned In 0.53 Ga 0.47 As substrate by comparing the forming gas annealing (at atmospheric pressure with a H 2 partial pressure of 0.04 bar) and H 2 high-pressure annealing (H 2 -HPA at 30 bar) methods. In addition, the effectiveness of H 2 -HPA on the passivation of the interface states was compared for both p- and n-type In 0.53 Ga 0.47 As substrates. The decomposition of the interface oxide and the subsequent out-diffusion of In and Ga atoms toward the high-k film became more significant with increasing H 2 pressure. Moreover, the increase in the H 2 pressure significantly improved the capacitance‒voltage characteristics, and its effect was more pronounced on the p-type In 0.53 Ga 0.47 As substrate. However, the H 2 -HPA induced an increase in the leakage current, probably because of the out-diffusion and incorporation of In/Ga atoms within the high-k stack.

    Nonresonant Raman scattering measurements were performed on a three-layered sample of in situ annealed InAs/GaAs self-assembled quantum dots. The thermal annealing step was done during the growth of each GaAs spacer layer, where the substrate temperature was raised from 530 deg. C to 580 deg. C as measured by a pyrometer. Three Raman signals are clearly seen at 264 cm -1 , 268 cm -1 , and 271.5 cm -1 which can be attributed to the longitudinal optic (LO) phonons of the dots. These three different signals are attributed to different degrees of In/Ga alloying or intermixing in each dot layer as a consequence of the different thermal treatments that each layer was subjected to. The Raman signal of the wetting layer (WL) is remarkably weak and suggests erosion of the wetting layer. In contrast, Raman scattering measurements on an unannealed sample show two overlapping features at 259.5 cm -1 and 261.5 cm -1 , which are attributed to the LO phonons of the dots. The WL signal is clearly observed at 251.5 cm -1 . To support our Raman observations, the appearance of a strong higher-energy peak in photoluminescence measurements suggests that alloying did occur in the annealed sample

    Full Text Available Objective. Forest remnants were analyzed to determine the density of squirrel monkeys (Saimiri sciureus and the degree of alteration of the forest, by selecting areas for the conservation and maintenance of the species in natural environments. Materials and methods. Linear transects were conducted on two wooden fragments, “La Reforma” and “Campo Hermoso” farms (Puerto Lopez, Meta, Colombia, recording sightings of squirrel monkeys and identifying the tree species used by the primates. Results. The fragments studied correspond to trails at the edge of water bodies with low connectivity. Highest density values were observed on the second transect of La Reforma, a possible consequence of an overcrowding phenomenon due to the high degree of isolation of the fragment. The species preferentially used as refuge and food source were: Bellucia grossularioides, Eugenia jambos, Inga alba, Mauritia flexuosa, Pseudolmedia laevis and Rollinia edulis. Conclusions. The phenology of the plant species allows for a dynamic food supply, considering the constant availability of food for the primates. Therefore, despite the evident ecological problem of these forests, it is possible to use active restoration programs to strengthen the existing dynamics and balance the biogeochemical dynamics of the ecosystem, so that socioeconomic human activities are not in conflict with conservation efforts and vice versa.

    Full Text Available Background: Choosing the correct species and fertilization treatments is a determining factor in the success of forest restoration. Methods: A field study was conducted in a degraded area near the Balbina hydroelectric dam in Amazonas State (AM, Brazil, to evaluate two hypotheses: (i leguminous tree species exhibit differences in growth, leaf nutrient content, and photosynthetic nutrient use efficiencies; and (ii differences in these characteristics depend on the fertilization treatments to which the species have been subjected. Dipteryx odorata, Inga edulis and Schizolobium amazonicum were subjected to the following treatments: (T1 unfertilized control; (T2 post-planting chemical fertilization; (T3 post-planting organic fertilization and (T4 combined chemical and organic post-planting fertilization. Results: In general, I. edulis had the highest absolute growth rate of biomass under all of the fertilization treatments. I. edulis and S. amazonicum showed the highest growth rates under the T4 treatment. D. odorata showed the greatest responses under the T2 and T4 treatments. Native leguminous trees with higher photosynthetic performance and better nutrient use efficiency exhibited greater growth and biomass production. Conclusion: The results suggest that an adequate balance between leguminous species selection and fertilization will aid in the success of forest restoration in Amazonia.

    Full Text Available ABSTRACT Amazonia is crucial to global carbon cycle. Deforestation continues to be one of the main causes of the release of C into the atmosphere, but forest restoration plantations can reverse this scenario. However, there is still diffuse information about the C and nutrient stocks in the vegetation biomass. We investigated the carbon and nutrient stocks of Fabaceae trees (Inga edulis, Schizolobium amazonicum and Dipteryx odorata subjected to fertilization treatments (T1 - no fertilization; T2 - chemical; T3 - organic; and T4 - organic and chemical fertilization in a degraded area of the Balbina Hydroelectric Dam, AM - Brazil. As an early successional species, I. edulis stocked more C and nutrients than the other two species independent of the fertilization treatment, and S. amazonicum stocked more C than D. odorata under T1 and T4. The mixed species plantation had the potential to stock 4.1 Mg C ha-1 year-1, while I. edulis alone could stock 9.4 Mg C ha-1 year-1. Mixing species that rapidly assimilate C and are of significant ecological and commercial value (e.g., Fabaceae trees represents a good way to restore degraded areas. Our results suggest that the tested species be used for forest restoration in Amazonia.

    The actual energy demand in Italy is met only in part by means of hydropower, as the available resources are almost entirely exploited. Italy is therefore obliged to import energy from far countries, in form of fossil fuel, that gives rise to serious outcomes due to the emission of undesirable gas in the environment. According to some recent evaluations conducted by the Ministry of Environment and the Agency for Alternative Energy (ENEA), the situation could improve in the year 2020 if the demand would reduce and the use of clean-energy increase. However, such an ambitious programme require to invest in ten years more than 100.000 billion Liras and the overall fuel consumption will only partially, decrease. To look at the problem in a broader view, taking into account that a drastic demand reduction is unthinkable, new resources, preferably non-polluting, must be identified. An energy source, still unexploited, is that of River Congo at the Inga falls, where the estimated potential is of 270 GWh, namely of the same order of the total energy consumed in Italy in 1997. Because such an energy cannot be conveyed to Italy by means of electric lines, it must be transformed into a vector suitable of an easier transportation: this could be the hydrogen [it

    Aim of this thesis was to apply the analytical methods of the scanning transmission electron microscopy to the study of self-organized In(Ga)As quantum structures. With the imaging methods Z contrast and bright field (position resolutions in the subnanometer range) and especially with the possibilities of the quantitative chemical EELS analysis of the scanning transmission electron microscope (STEM) fundamental questions concerning morphology and chemical properties of self-organized quantum structures should be answered. By the high position resolution of the STEM among others essentail morphological and structural parameters in the growth behaviour of ''dot in a well'' (DWell) structures and of vertically correlated quantum dots (QDs) could be analyzed. For the optimization of DWell structures samples were studied, the nominal InAs-QD growth position was directedly varied within the embedding InGaAs quantum wells. The STEM offers in connection with the EELS method a large potential for the chemical analysis of quantum structures. Studied was a sample series of self-organized InGaAs/GaAs structures on GaAs substrate, the stress of which was changed by varying the Ga content of the INGaAs material between 2.4 % and 4.3 % [de

It was observed that this specie is colonized by endophitic fungi and that there is a significant difference in the degree of colonization in the different samples analyzed. In relation to the colonization, it was observed that Xylaria and Phomopsis were found in all organs sampled. The genera Alternaria and Fusarium demonstrated specificity in seed; Nigrospora and Aspergillus in leaf and Dothiorella in stem. The curves of accumulation of species for leaf and stem followed a similar pattern, showing a slow accumulation of species along the sampling, indicating that a larger sampling could result in a significant increment of new taxons.

    This paper is about the wood anatomy of 31 species, belonging to 17 genera, of the Mimosoideae subfamily (Leguminosae), proceeding from different geographical regions of Venezuela. For each species, one to five individuals were studied. The descriptions were realized according to the IAWA Committee(1989). The studied species may be divided in two groups according to the presence or absence of septate fibers. All species of Inga showed septate fibers, whereas Albizia and Enterolobium included species with septate fibers and also species with non-septate fibers. The quantitative characteristics of the vessels and the width of rays showed sufficient variation as to be considered important characteristics from ataxonomic point of view. The most common parenchyma type was vasicetric, aliform and confluent. In Calliandra laxa, Prosopis juliflora and Zygia longifolia the main parenchyma type was in wide bands; whereas in Cedrelinga cateniformis, the main parenchyma type was thin vasicentric. All species studied, with the exception of Cedrelinga cateniformis, presented prismatic crystals in the parenchymatous axials cells. In spite of finding certain anatomical uniformity, it was possible to elaborate a key for the identification of the studied species.

    Full Text Available The degradation status of the forests in western Santa Catarina state reflects in a reduced number of conserved areas that enable studies on forest communities diversity and structure in order to create strategies for ecosystems preservation, management and restoration. The objective of this study was to describe the diversity and structure of a forest remnant of Seasonal Submontane Deciduous Forest located in the municipality of São João do Oeste, Santa Catarina state. For the inventory, we demarcated 102 sampling units of 10 × 10 m, continuously arranged in a grid of 6 × 17 plots, in which all plants of the arborescent-arboreal sinusiae with perimeter at breast height (PBH ≥ 15 cm were sampled. We surveyed 1441.18 living trees and 93.14 standing dead plants per ha. The 79 species found belong to 61 genera and 33 families. Sorocea bonplandii , Nectandra megapotamica , Inga marginata , Ocotea diospyrifolia and Trichilia claussenii presented the highest importance value indexes. The Shannon diversity index (H’ was 3.21 and the Pielou equability (J’ was 0.735. The vertical structure of the vegetation sampled was divided into treelets (2-11 m, canopy (12-17 m and emerging trees (18-25 m. The studied forest fragment is an important reference ecosystem for the implementation of strategies for preservation, management and restoration of seasonal forests.

    Full Text Available Active restoration is one strategy to reverse tropical forest loss. Given the dynamic nature of climates, human populations, and other ecosystem components, the past practice of using historical reference sites as restoration targets is unlikely to result in self-sustaining ecosystems. Restoring sustainable ecological processes like pollination is a more feasible goal. We investigated how flower cover, planting design, and landscape forest cover influenced bird pollinator visits to Inga edulis trees in young restoration sites in Costa Rica. I. edulis trees were located in island plantings, where seedlings had been planted in patches, or in plantation plantings, where seedlings were planted to cover the restoration area. Sites were located in landscapes with scant (10–21% or moderate (35–76% forest cover. Trees with greater flower cover received more visits from pollinating birds; neither planting design nor landscape forest cover influenced the number of pollinator visits. Resident hummingbirds and a migratory bird species were the most frequent bird pollinators. Pollination in the early years following planting may not be as affected by details of restoration design as other ecological processes like seed dispersal. Future work to assess the quality of various pollinator species will be important in assessing this idea.

    Changes in commodity prices, such as the fall in coffee prices from 2000 to 2004, affect land use decisions on farms, and the environmental services they provide. A survey of 50 farms showed a 35 % loss in the area under coffee between 2000 and 2004 below 700 m with the majority of this area (64 %) being coffee agroforest systems that included native forest species. Loss of coffee only occurred on large and medium-scale farms; there was no change in area on cooperatives. Coffee productivity declined below 1,100 m altitude for sun and Inga shade coffee, but only below 700 m altitude for agroforest coffee. Coffee productivity was 37-53 % lower under agroforests than other systems. Increases in rubber and pasture were related to low altitude large-scale farms, and bananas and timber plantations to mid-altitude farms. Average aboveground carbon stocks for coffee agroforests of 39 t C ha-1 was similar to rubber plantations, but one-third to one half that of natural forest and timber plantations, respectively. Coffee agroforests had the highest native tree diversity of the productive systems (7-12 species ha-1) but lower than natural forest (31 species ha-1). Conversion of coffee agroforest to other land uses always led to a reduction in the quality of habitat for native biodiversity, especially avian, but was concentrated among certain farm types. Sustaining coffee agroforests for biodiversity conservation would require targeted interventions such as direct payments or market incentives specifically for biodiversity.

    The aim of this work was to find palynological markers which permit differentiate honeys from the departments of Boyaca, Cundinamarca, Santander and Magdalena, by its geographical and botanical origin. Melissopalynological analyses were made of 184 honey samples obtained from 131 localities. A discriminant analysis and comparisons between the species composition of honey samples were made to find geo-graphical and botanical origin differences. A total of 297 pollen species distributed in 69 families was found, being Mimosa sp., Cecropia sp., Eucalyptus sp., Piper sp. and Quercus humboldtii the most representatives. The major families were Fabaceae, Asteraceae, Myrtaceae, Rubiaceae, Fagaceae and Melastomataceae. Six honey groups differentiated by its geographical origin were found: Altiplano Cundiboyacense, Medio Chicamocha, Sumapaz, Bajo Chicamocha, Sierra Nevada de Santa Marta and Comunera Province. In a broader scale, honeys from the Andean and sub-Andean regions could be differentiated as well. Between the honey types differentiated by its botanical origin, the most important were monofloral honeys of Trifolium pratense, Coffea arabica, Eucalyptus sp., Inga sp. and Heliocarpus americanus, Asteraceae oligofloral honeys and mixtures of Q. humboldtii honeydew and floral nectar (Eucalyptussp., Brassicaceae Type, Asteraceae). This information in addition to the obtained by physico-chemical and sensorial analysis, may be the basis to acquire honeys' origin denomination.

    Local food diversity and traditional crops are essential for cost-effective management of the global epidemic of type 2 diabetes and associated complications of hypertension. Water and 12% ethanol extracts of native Peruvian fruits such as Lucuma (Pouteria lucuma), Pacae (Inga feuille), Papayita arequipeña (Carica pubescens), Capuli (Prunus capuli), Aguaymanto (Physalis peruviana), and Algarrobo (Prosopis pallida) were evaluated for total phenolics, antioxidant activity based on 2, 2-diphenyl-1-picrylhydrazyl radical scavenging assay, and functionality such as in vitro inhibition of alpha-amylase, alpha-glucosidase, and angiotensin I-converting enzyme (ACE) relevant for potential management of hyperglycemia and hypertension linked to type 2 diabetes. The total phenolic content ranged from 3.2 (Aguaymanto) to 11.4 (Lucuma fruit) mg/g of sample dry weight. A significant positive correlation was found between total phenolic content and antioxidant activity for the ethanolic extracts. No phenolic compound was detected in Lucuma (fruit and powder) and Pacae. Aqueous extracts from Lucuma and Algarrobo had the highest alpha-glucosidase inhibitory activities. Papayita arequipeña and Algarrobo had significant ACE inhibitory activities reflecting antihypertensive potential. These in vitro results point to the excellent potential of Peruvian fruits for food-based strategies for complementing effective antidiabetes and antihypertension solutions based on further animal and clinical studies.

A espécie Sclerolobium paniculatum foi plantada somente no espaçamento 2 m x 1 m. Na condução do experimento, o milho permaneceu no experimento nos primeiros quatro meses e considerado como monocultura, produziu 1.890 +/- 32 kg ha-1. A sobrevivência das árvores, plantadas junto com milho e na mesma época da mandioca, não sofreu interferência negativa das culturas agrícolas. Independente do espaçamento, as árvores não causaram impacto negativo no peso seco das raízes de mandioca. Quanto a densidade de árvores observou-se tendência de aumento do peso seco das raízes de mandioca com a diminuição do número de árvores plantadas por hectare. Os resultados evidenciam a possibilidade de se manter a produtividade agrícola associada ao plantio de árvores. Entretanto, a opção pelo espaçamento 1 m x 1 m deve ser cuidadosamente analisada quando o objetivo principal for a produção de alimentos.

    Full Text Available As inúmeras espécies de plantas que compõem a floresta amazônica podem representar excelente alternativa para fazer frente ao desafio de desenvolver a agricultura conforme as exigências da sociedade. Neste trabalho, procurou-se determinar e caracterizar o padrão de atividade alelopática em espécies da família Leguminosae, em função de variações de espécies, fonte de extratos e sensibilidade da planta receptora. Bioensaios de germinação de sementes e alongamento da radícula e do hipocótilo foram desenvolvidos em condições controladas. Os resultados indicam que as espécies estudadas não apresentaram padrão semelhante no tocante aos efeitos potenciais alelopáticos, havendo, entretanto, hierarquização no tocante à intensidade dos efeitos globais, sendo o potencial alelopático inibitório mais amplo e efetivo nas espécies Bauhinia guianensis, Bowdichia virgiloides, Parkia pendula e Platimenia reticulata. O potencial alelopático foi efetivo e mais restrito em Bauhinia macrostachya. O fator fração das plantas revelou diferenciação no padrão de atividade: para a maioria das espécies, as folhas foram a principal fonte de aleloquímicos, e para Bauhinia macrostachya e Inga edulis, a raiz. Em termos de padrão de respostas das espécies receptoras, o alongamento da radícula é mais sensível aos efeitos dos extratos, ficando o alongamento do hipocótilo como o de menor sensibilidade. Os efeitos dos extratos foram mais intensos sobre Mimosa pudica. Esses resultados também atribuem à floresta amazônica importância como fonte de compostos químicos de interesse para o homem, o que, em si, justifica sua preservação.Innumerous plant species in the Amazon forest may be an excellent alternative to meet society's demand for natural products.

    Full Text Available Shade-grown coffee is an agricultural system that contains some forest-like characteristics. However, structure and diversity are poorly known in shade coffee systems. In 61 coffee-growers’ plots of Chiapas, Mexico, structural variables of shade vegetation and coffee yields were measured, recording species and their use. Coffee stands had five vegetation strata. Seventy seven woody species mostly used as wood were found (mean density 371.4 trees per hectare. Ninety percent were native species (40% of the local flora, the remaining were introduced species, mainly fruit trees/shrubs. Diametric distribution resembles that of a secondary forest. Principal Coordinates Analysis grouped plots in four classes by the presence of Inga, however the majority of plots are diverse. There was no difference in equitability among groups or coffee yields. Coffee yield was 835 g clean coffee per shrub, or ca. 1668 kg ha-1. There is a significant role of shade-grown coffee as diversity refuge for woody plants and presumably associated fauna, as well as an opportunity for shade-coffee growers to participate in the new biodiversity-friendly-coffee marketEl café bajo sombra es un sistema agrícola que contiene algunas características de los bosques.

Quantum dots could be aligned and cross hatched. Quantum rings (QRs created from quantum dot transformation during thin or partial capping are used as templates for the formations of bi-quantum dot molecules (Bi-QDMs and quantum dot rings (QDRs. Preferable quantum dot nanostructure for quantum computation based on quantum dot cellular automata (QCA is laterally close-packed quantum dot molecules having four quantum dots at the corners of square configuration. These four quantum dot sets are called quadra-quantum dots (QQDs. Aligned quadra-quantum dots with two electron confinements work like a wire for digital information transmission by Coulomb repulsion force, which is fast and consumes little power. Combination of quadra-quantum dots in line and their cross-over works as logic gates and memory bits. Molecular Beam Epitaxial growth technique called ‘‘Droplet Epitaxy” has been developed for several quantum nanostructures such as quantum rings and quantum dot rings.

    Full Text Available Laterally close-packed quantum dots (QDs called quantum dot molecules (QDMs are grown by modified molecular beam epitaxy (MBE. Quantum dots could be aligned and cross hatched. Quantum rings (QRs created from quantum dot transformation during thin or partial capping are used as templates for the formations of bi-quantum dot molecules (Bi-QDMs and quantum dot rings (QDRs. Preferable quantum dot nanostructure for quantum computation based on quantum dot cellular automata (QCA is laterally close-packed quantum dot molecules having four quantum dots at the corners of square configuration. These four quantum dot sets are called quadra-quantum dots (QQDs. Aligned quadra-quantum dots with two electron confinements work like a wire for digital information transmission by Coulomb repulsion force, which is fast and consumes little power. Combination of quadra-quantum dots in line and their cross-over works as logic gates and memory bits. Molecular Beam Epitaxial growth technique called 'Droplet Epitaxy' has been developed for several quantum nanostructures such as quantum rings and quantum dot rings.

    Xe isotopes in A∼130 mass region are known for their variety of structural phenomena, such as, unexpected signature splitting, signature inversion, γ-vibration etc. These phenomena are associated to axialy asymmetric shape. The triaxial shape in Xe nuclei are expected to originate due to the availability of prolate driving low-Ω πh_1_1_/_2 orbital and oblate driving high-Ω νh11/2 orbital near Fermi surface. The observed experimental E (4"+)/E (2"+) value (∼2.5) also support the γ-soft nature of these nuclei. Interestingly, both proton and neutron alignments have been observed in νh_1_1_/_2 band in "1"1"9"-"1"2"5Xe and neutron alignment dominates. In "1"2"9Xe, proton alignment reported to dominate. It is also supported by TPRM calculations, although, there are no significant change in the neutron orbitals. Whether this change in the alignment is occurred at N=75 or 73 is not known. Therefore, it is interesting to understand the status of the neutron and proton alignment in "1"2"7Xe, which are not studied well. Hence, in-beam γ-ray spectroscopy of "1"2"7Xe was carried out using "1"2"2Sn("9Be, 4nγ) fusion-evaporation reaction at 48 MeV using INGA facility at Inter-University Accelerator Centre, New Delhi. Details of the analysis and results will be discussed during the conference. (author)

ESBLs with CTX-M enzymes have been isolated from animals and different food products, but it is unknown if food imported from the Mediterranean area may be a possible reservoir of these bacteria. During 2007–2008, swab samples from food across different retail outlets (mostly food from the Mediterranean countries and Swedish chicken were collected. Escherichia coli strains from Swedish meat and E. coli isolates from unspecified food from a Swedish food testing laboratory were also examined. In 349 of the 419 swab samples, growth of Enterobacteriaceae was found. In most of the samples, there was also growth of Gram-negative environmental bacteria. Air dry-cured products contained significantly less Enterobacteriaceae isolates compared to lettuces; however, none of the examined Enterobacteriaceae harbored ESBLs. This study did not support the theory that imported food from the Mediterranean area or Swedish domestic food might constitute an important vehicle for the dissemination of ESBL-producing Enterobacteriaceae; however, a spread from food to humans may have occurred after 2008.Keywords: ESBL, antibiotic resistance, zoonosis, food, Enterobacteriaceae

  3. Southern African Power Pool: Planning and Prospects for Renewable Energy

    With the energy systems of many African countries dominated by fossil-fuel sources that are vulnerable to global price volatility, regional and intra-continental power systems with high shares of renewable energy can provide least-cost option to support continued economic growth and address the continent’s acute energy access problem. Unlocking Africa’s huge renewable energy potential could help to take many people out of poverty, while ensuring the uptake of sustainable technologies for the continent’s long-term development. The report examines the ''renewable scenario'' based on a modelling tool developed by IRENA and tested in cooperation with the South African National Energy Development Institute (SANEDI) and the Southern African Development Community (SADC). Initial results from the System Planning and Test (SPLAT) model show that the share of renewable technologies in Southern Africa could increase from the current 10% to as much as 46% in 2030, with 20% of decentralised capacity coming from renewable sources and nearly 80% of the envisaged capacity additions between 2010 and 2030 being provided by renewable energy technologies. Deployment and export of hydropower from the Democratic Republic of Congo’s Inga hydropower project to the SADC region would significantly reduce average electricity generation costs. Analysis using SPLAT – along with a similar model developed for West Africa – can provide valuable input for regional dialogue and energy projects such as the East and Southern Africa Clean Energy Corridor and the Programme for Infrastructure and Development in Africa (PIDA). IRENA, together with partner organisations, has started plans to set up capacity building and development support for energy system modelling and planning for greater integration of renewables in Africa. IRENA is also completing a similar model and study for East Africa and intends to extend this work to Central and North Africa.

    Full Text Available The objective was to assess the effects of natural variation in the physical structure of the environment on biological communities and on the processing of Eucalyptus cloeziana and Inga laurina and to identify the controlling factors at different scales along stream order gradients. The study area consisted of 14 sampling sites distributed within a tropical watershed (1st, 2nd, 3rd and 4th order streams replicated in 4 sub-basins. Our samples consisted of 3 g of leaves of E. cloeziana (high-quality and I. laurina (low-quality placed in 252 bags with 10mm mesh (measured by the chemical composition of the detritus. Four samples of each leaf type were collected periodically (three times over a period of 75-125 days and washed on a sieve to separate the invertebrates. A series of leaf disks were cut to determine ash-free dry mass, polyphenol, lignin, cellulose, total microbial biomass and fungal biomass, and the remaining material was oven-dried to determine the dry weight. We performed analyses within and between spatial scales (regional and local to assess which watershed scale was the more import determinant of the leaf breakdown rate (k. The microbial and shredder were most influenced at the local scale (stream order. Shredders were influenced by microorganisms, with stronger interactions between them than were found to drive the k at the local scale. Moreover, differences in the overall k and abiotic variables were more strongly influenced at the regional scale (sub-basin, showing that the study scale alters the response of the studied variables. We found higher k values at higher values of water velocity, dissolved oxygen and temperature, all of which accelerate biological metabolism in response to variations on the regional scale. Watersheds with warmer microclimates and streams with higher nutrient levels and oxygen could be accelerating the ecosystem metabolism, independent of the detritus quality.

    A set of sediment cores was sampled at Sepetiba bay and Ribeira bay, in the Rio de Janeiro State, Brazil. Sedimentation rates were determined by geochronological evaluation of sediments by Pb-210. In Ribeira Bay, the sedimentation rate increases from the sampling point RB1 (0.15 cm y -1 ), in the inner part of the bay, towards the sampling point RB4, close to its entrance (0.34 cm y -1 ). For Sepetiba Bay, two well-defined sedimentation rates were observed, a lower value of 0.3 cm y -1 for the period before the 1960s, and a more recent rate of 0.75 cm y -1 . These measurements are consistent to the construction of the Santa Cecilia impoundment in 1955, which brings water from the Paraiba do Sul Basin into the Guandu River, increasing the river flow from 20 m 3 s -1 to 160 m 3 s -1 . The metal concentrations were determined by ICP-MS. It could be seen that the reliability of Ribeira bay as a reference database for metal concentrations in the neighboring Sepetiba Bay is valid for a specific set of elements, such as K, Ti, Mn, Zn, Ga, Rb and Sr, but not for V, Cr and Cd. Applying to the mean elemental concentration, of the upper contaminated 45 cm sediment layer, and to the elemental concentration of the deepest analysed sediment layer a normalization to iron, a double ratio was calculated and it was concluded that the Sepetiba Bay sediments are, particularly, contaminated with Cr, may be, from a leather tanning plant existing in this region and Cd and Zn from the former Inga Metais. The overall results can be used to confirm the reliability of the utilization of Ribeira bay as a reference database to the evaluation of metal pollution profile of Sepetiba bay, by an intercomparison methodology.

Information on frugivorous flies in cultivated or wild host plants and their parasitoids in the Cerrado-Pantanal ecotone in Aquidauana, Mato Grosso do Sul is presented and discussed. Fruit fly samples were collected weekly in specific fruit trees, and McPhail® traps were installed in the same trees for a period of two years. The fruit flies infested ripe and unripe fruits of Averrhoa carambola L., Schoepfia sp., Psidium guajava L. and Pouteria torta (Mart. Radlk and mature fruits of Anacardium occidentale L. and Inga laurina (Sw. Willd. Nineteen fruit fly species were obtained with the combination of sampling methods (collecting fruits and trapping, nine of them obtained with both methods, five found only in fruits and five only in traps. This is the first record of Anastrepha striata Schiner in a species of Sapotaceae, as well as for A. castanea Norrbom and A. daciformes Bezzi in Schoepfia sp. (Olacaceae, and for A. distincta Greene in fruits of P. guajava in the state of Mato Grosso do Sul. Fruit collections simultaneously associated with capture of fruit flies by McPhail traps in the same host plants are essential to understand the diversity of fruit flies and their relationship with hosts and parasitoids. Species of Braconidae and Pteromalidae were recovered, where Doryctobracon areolatus (Szépligeti was the most abundant parasitoid in larvae of tephritids infesting both cultivated and wild host fruits.

According to the updated guidelines, the greatest efficacy in cardiac massage is only achieved when the right compression point, an adequate compression depth, vertical pressure, the correct frequency, and equally long phases of compression and decompression are achieved. The very highest priority is placed on restoring continuous circulation. Against this background, standardized continuous chest compression with active decompression has contributed to a favorable outcome in this case. The hydraulically operated and variably adjustable automatic Lund University Cardiac Arrest System (LUCAS device (Jolife, Lund, Sweden undoubtedly meets these requirements. This case report describes a 44-year-old patient who – approximately 15 min after the onset of clinical death due to apparent ventricular fibrillation – received cardiopulmonary resuscitation, initially by laypersons and then by the emergency medical team (manual chest compressions followed by situation-adjusted LUCAS compressions. Sinus rhythm was restored after more than 90 min of continuous resuscitation, with seven defibrillations.

    Informal support is essential for enabling many older people to age in place. However, there is limited research examining the information needs of older adults' informal support networks and how these could be met through home monitoring and information and communication technologies. The purpose of this study was to investigate how technologies that connect older adults to their informal and formal support networks could assist aging in place and enhance older adults' health and well-being. Semistructured interviews were conducted with 10 older adults and a total of 31 members of their self-identified informal support networks. They were asked questions about their information needs and how technology could support the older adults to age in place. The interviews were transcribed and thematically analyzed. The analysis identified three overarching themes: (1) the social enablers theme, which outlined how timing, informal support networks, and safety concerns assist the older adults' uptake of technology, (2) the technology concerns theme, which outlined concerns about cost, usability, information security and privacy, and technology superseding face-to-face contact, and (3) the information desired theme, which outlined what information should be collected and transferred and who should make decisions about this. Older adults and their informal support networks may be receptive to technology that monitors older adults within the home if it enables aging in place for longer. However, cost, privacy, security, and usability barriers would need to be considered and the system should be individualizable to older adults' changing needs. The user requirements identified from this study and described in this paper have informed the development of a technology that is currently being prototyped. ©Phoebe Elers, Inga Hunter, Dick Whiddett, Caroline Lockhart, Hans Guesgen, Amardeep Singh.

  13. The electronic properties of semiconductor quantum dots

    International Nuclear Information System (INIS)

    Barker, J.A.

    2000-10-01

    This work is an investigation into the electronic behaviour of semiconductor quantum dots, particularly self-assembled quantum dot arrays. Processor-efficient models are developed to describe the electronic structure of dots, deriving analytic formulae for the strain tensor, piezoelectric distribution and diffusion- induced evolution of the confinement potential, for dots of arbitrary initial shape and composition profile. These models are then applied to experimental data. Transitions due to individual quantum dots have a narrow linewidth as a result of their discrete density of states. By contrast, quantum dot arrays exhibit inhomogeneous broadening which is generally attributed to size variations between the individual dots in the ensemble. Interpreting the results of double resonance spectroscopy, it is seen that variation in the indium composition of the nominally InAs dots is also present. This result also explains the otherwise confusing relationship between the spread in the ground-state and excited-state transition energies. Careful analysis shows that, in addition to the variations in size and composition, some other as yet unidentified broadening mechanism must also be present. The influence of rapid thermal annealing on dot electronic structure is also considered, finding that the experimentally observed blue-shift and narrowing of the photoluminescence linewidth may both be explained in terms of normal In/Ga interdiffusion. InAs/GaAs self-assembled quantum dots are commonly assumed to have a pyramidal geometry, so that we would expect the energy separation of the ground-state electron and hole levels in the dot to be largest at a positive applied field. This should also be the case for any dot of uniform composition whose shape tapers inwards from base to top, counter to the results of experimental Stark-shift spectroscopy which show a peak transition energy at a negative applied field. It is demonstrated that this inversion of the ground state

    Full Text Available http://dx.doi.org/10.5902/1980509815736This study aims to indicate native species to be used in the restoration of degraded riparian forests in the subwatershed of Peixe-Boi river. All trees and shrubs with diameter at breast height (DBH > 5 cm were inventoried in ten areas of secondary forest and six areas of igapó forest. The results were analyzed by Principal Component Analysis and the silviculture of the species was assessed by literature review. In Igapó areas 66 species were found; the areas had low richness and low diversity index of Shannon, when compared with data from the secondary forests. The floristic composition was heterogeneous, and the floristic similarity is higher between areas that are closer geographically. In the secondary forests were found 175 species; the areas showed high abundance of individuals, high species richness, diversity and evenness. Secondary forests were separated according to geographic proximity and age, which is directly linked to the successional stage. The PCA analysis established the ecological importance of 29 tree species; however only ten species had enough silvicultural information. Due to a greater ecological importance and viable silvicultural techniques available in the literature, Carapa guianensis, Pachira aquatica, Spondias mombin, Tapirira guianensis and Virola guianensis are the most suitable species to restore the degraded areas, in association with Inga edulis, Jacaranda copaia, Pseudopiptadenia psilostachya, Simarouba amara and Vismia guianensis of the secondary forests, that can be planted in the borders and in the nearby areas of igapó forests.

Arboreal plants of the Cerrado biome showed increased mycorrhizal colonization from inoculation with Glomus clarum, except chichá, as this species showed a high indigenous colonization, not differing from the colonization promoted by inoculated fungi. Inoculation promoted increased growth in baru, gabiroba, ingá, caroba and chichá, increasing shoot dry matter (MSPA and root dry matter (MSR. In caroba, this effect was synergistic with application of P to the soil. Baru and jatobá showed increased dry matter with application of P to the soil only. The mycotrophy (mycorrhizal dependence of species and their response to inoculation and to phosphorus are discussed. In order to produce quality seedlings of caroba, gabiroba, chichá and ingá, combining inoculation with Glomus clarum and phosphate fertilization of the soil is recommended, while for jatobá and baru only the application of P to the soil is recommended.

    The CuGaSe 2 is a perspective material for use as a solar elements. In the present work the results of investigation of the dependence of current of short circuit from wavelength of incident light in the fundamental absorption range of both initial and radiated p-CuGaSe 2 samples. The investigation were carried out on low resistance (ρ=10 2 Ω·cm) monocrystalline samples at 77 K, obtained by gas transport reactions. The eutectic In-Ga was use as a contacts. Co 60 with 1.25 MeV quantum energy was the source of radiation. The dependence of the short circuit current from wavelength of the non radiated sample has dome-like form with maxima of 730 nm. The dependence of the short circuit current with the wavelength was measured on this sample after continuous radiation by γ-quantum with capacity of 300 R/s within 20 hours. The saturation is observed with the increasing of wavelength from 400 nm to 690 nm, at the further increasing the current of short circuit takes negative magnitude with the minima of 730 nm and increases to 800 nm and further takes positive magnitude. Thus the inverse of the short circuit current is observed. The experiment was repeated. After the radiation the resistance of samples was increased by three order (from kΩ to MΩ). Such behavior of the dependence of the short circuit current with wavelength testifies, on seen, to change the conductivity, i.e. p-CuGaSe 2 samples are got n-type conductivity under the influence of γ-radiation. Under the influence of γ-radiation the the defects increases, which influences as the scattering electronic centers. The number of electronic centres increases with dose and intensity of γ-radiation which changes the conductivity type

    Coherent (InN) 1 /(GaN) n short-period superlattices (SPSs) were successfully grown through dynamic atomic layer epitaxy (D-ALEp) mode by RF-plasma molecular beam epitaxy (MBE), where GaN layer thicknesses n were thinned down to 4 monolayer (ML). After this achievement, we demonstrated quasi-ternary InGaN behavior in their photoluminescence (PL) spectra for the first time. It was found interestingly that GaN layer thickness of n = 4 ML was the criterion both for structural control and continuum-band formation. Although highly lattice-mismatched InN/GaN interfaces easily introduce relaxation in (InN) 1 /(GaN) 4 SPSs during growth depending on the dynamic surface stoichiometry condition, this problem was overcome by precise control/removal of fluid-like residual In/Ga metals on the growth front with in-situ monitoring method. The (InN) 1 /(GaN) n SPSs with n ≥ 7 ML showed a constant PL peak energy around 3.2 eV at 12 K, reflecting discrete electron/hole wavefunctions. On the other hand, the (InN) 1 /(GaN) 4 SPSs indicated the red-shifted PL peak at 2.93 eV at 12 K, which was attributed to the continuum-band state with increasing in the overlap of electrons/hole wavefunctions. This result is concluded that the (InN) 1 /(GaN) 4 SPSs can be considered as ordered InGaN alloys. (copyright 2015 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    Establishing diverse mycorrhizal fungal communities is considered important for forest recovery, yet mycorrhizae may have complex effects on tree growth depending on the composition of fungal species present. In an effort to understand the role of mycorrhizal fungi community in forest restoration in southern Costa Rica, we sampled the arbuscular mycorrhizal fungal (AMF) community across eight sites that were planted with the same species ( Inga edulis, Erythrina poeppigiana, Terminalia amazonia, and Vochysia guatemalensis ) but varied twofold to fourfold in overall tree growth rates. The AMF community was measured in multiple ways: as percent colonization of host tree roots, by DNA isolation of the fungal species associated with the roots, and through spore density, volume, and identity in both the wet and dry seasons. Consistent with prior tropical restoration research, the majority of fungal species belonged to the genus Glomus and genus Acaulospora , accounting for more than half of the species and relative abundance found on trees roots and over 95% of spore density across all sites. Greater AMF diversity correlated with lower soil organic matter, carbon, and nitrogen concentrations and longer durations of prior pasture use across sites. Contrary to previous literature findings, AMF species diversity and spore densities were inversely related to tree growth, which may have arisen from trees facultatively increasing their associations with AMF in lower soil fertility sites. Changes to AMF community composition also may have led to variation in disturbance susceptibility, host tree nutrient acquisition, and tree growth. These results highlight the potential importance of fungal-tree-soil interactions in forest recovery and suggest that fungal community dynamics could have important implications for tree growth in disturbed soils.

  4. Plant food resources and the diet of a parrot community in a gallery forest of the southern Pantanal (Brazil

    Full Text Available Neotropical parrots usually forage in forest canopies for nectar, flowers, leaves, fruit pulp, and seeds. As they have no all-purpose territories, these birds usually exploit vegetation mosaics in order to use plentiful resources as they become available. In this study we examine the use of a gallery forest in the southern Pantanal (Brazil by a diverse parrot community that ranged from Brotogeris chiriri (a small species to Ara chloroptera (a large one. Plant food resources principally used by parrots were abundantly available during the rainy season (fleshy fruits, the annual floods (fleshy fruits, and the dry season (flowers. While both smaller and larger species foraged on fruits, parakeets largely consumed the pulp, while larger parrot species used pulp and seeds. In the dry season parakeets foraged extensively on nectar, especially Inga vera nectar that was abundantly available during the last two months of the dry season, the harshest period of the year. Among larger parrots, only Propyrrhura auricollis frequently harvested nectar. Fruits maturing during floods, despite being fish- or water- dispersed were extensively used by the parrots. Hence, unlike what happens in most other Neotropical dry forests, occurrence of a fruiting peak during the annual flooding, which occurs in the transition from the wet to the dry season, constitutes an extra and significant episode of food availability, since in this period, fruit production normally declines. Therefore, the unique and abundant availability of flowers and fruits in this gallery forest may account for the presence of large parrot populations in the southern Pantanal.

    Full Text Available The Petersburg text of Russian literature and the Vilnius text of Lithuanian literature: once again on the analytical visa of Vladimir Toporov’s concept Inga Vidugiryte Summary The concept Petersburg text by Toporov is criticized for its mythological essence, for the confusion of the languages of the object and the analysis in its description, and for the very attempt to create a mental space in which one can escape politics and ideology. The point of such critique is that the concept of Petersburg text is a product of the Soviet era and its highly ideologized atmosphere, as well as of the wish of the intellectuals not to participate in it. Nevertheles, there is a range of texts of cities or regions made by analogy with the Petersburg text (e.g., Moscow, Permj, Siberian, Crimean texts in the recent Russian humanities. In this article, the author makes an attempt to show the actuality of the Toporov’s concept by comparing it with the modern geocritical theory that does not make a strict separation between cities and texts and treats them as transgressive and mobile. On the other hand, it is stated that the concept of Toporov gains its actuality in discussing the text of the city in its relation to the main historical event of the nation, viz. the founding of Petersburg. This thesis could be proved by applying the notion to Vilnius and its literature. The main event of the modern Lithuanian history concerning Vilnius is the fact that it was given over to Lithuania in 1939. It took another 40 years to create the Vilnius text of Lithuanian literature, in which heroes and their stories are inseparable from the city and its history as well as from its topography. This means that Vilnius and its semiotics have been assimilated by Lithuanian culture, and the city has acquired its text.

    Full Text Available The distribution of b-globin gene haplotypes was studied in 209 Amerindians from eight tribes of the Brazilian Amazon: Asurini from Xingú, Awá-Guajá, Parakanã, Urubú-Kaapór, Zoé, Kayapó (Xikrin from the Bacajá village, Katuena, and Tiriyó. Nine different haplotypes were found, two of which (n. 11 and 13 had not been previously identified in Brazilian indigenous populations. Haplotype 2 (+ - - - - was the most common in all groups studied, with frequencies varying from 70% to 100%, followed by haplotype 6 (- + + - +, with frequencies between 7% and 18%. The frequency distribution of the b-globin gene haplotypes in the eighteen Brazilian Amerindian populations studied to date is characterized by a reduced number of haplotypes (average of 3.5 and low levels of heterozygosity and intrapopulational differentiation, with a single clearly predominant haplotype in most tribes (haplotype 2. The Parakanã, Urubú-Kaapór, Tiriyó and Xavante tribes constitute exceptions, presenting at least four haplotypes with relatively high frequencies. The closest genetic relationships were observed between the Brazilian and the Colombian Amerindians (Wayuu, Kamsa and Inga, and, to a lesser extent, with the Huichol of Mexico. North-American Amerindians are more differentiated and clearly separated from all other tribes, except the Xavante, from Brazil, and the Mapuche, from Argentina. A restricted pool of ancestral haplotypes may explain the low diversity observed among most present-day Brazilian and Colombian Amerindian groups, while interethnic admixture could be the most important factor to explain the high number of haplotypes and high levels of diversity observed in some South-American and most North-American tribes.

  10. Distinguishing "new" from "old" carbon in post mining soils

    Vindušková, Olga; Frouz, Jan

    2014-05-01

    Introduction Soils developing on heaped overburden after open pit coal mining near Sokolov, Czech Republic, provide an exceptional opportunity to study sites of different ages (0-70 years) developing on similar substrate under relatively well-known conditions. Soil organic carbon (SOC) is an useful indicator of soil quality and represents an important global carbon pool. Post-mining soils would be a perfect model for long-term study of carbon dynamics. Unfortunately, quantifying SOC in Sokolov post-mining soils is quite complicated, since conventional quantification methods cannot distinguish between SOC derived from plant residues and fossil organic carbon derived from coal and kerogen present in the overburden. Moreover, also inorganic carbon may sometimes bias SOC quantification. Up to now, the only way to directly estimate recently derived SOC in these soils is radiocarbon dating (Rumpel et al. 1999; Karu et al. 2009). However, this method is costly and thus cannot be used routinely. The aim of our study is to find an accessible method to quantify recently derived SOC. We would highly appreciate ideas of other soil scientists, organic geochemists and sedimentologists on how to solve this challenge. Methods and hypotheses A set of 14 soil samples were analysed by radiocarbon (14C-AMS) analysis, near-infrared spectroscopy (NIRS), 13C CPMAS NMR spectroscopy, Rock-Eval and XRD. For calibration of NIRS, also 125 artificial mixtures were produced by mixing different amounts of claystone, coal and partially decomposed litter. NIRS (1000-2500 nm) as well as younger mid-infrared spectroscopy has been widely applied to soils (Janik et al. 2007; Vasques et al. 2009; Michel et al. 2009). When combined with multivariate chemometric techniques, it can be used to predict concentration of different compounds. No study has yet focused on NIRS application to soils where fossil carbon is found in two chemically different forms - whereas coal is rather aromatic, kerogen in our

    Purpose: Small-animal studies require images with high spatial resolution and high contrast due to the small scale of the structures. X-ray imaging systems for small animals are often limited by the microfocus source. Here, the authors investigate the applicability of liquid-metal-jet x-ray sources for such high-resolution small-animal imaging, both in tomography based on absorption and in soft-tissue tumor imaging based on in-line phase contrast. Methods: The experimental arrangement consists of a liquid-metal-jet x-ray source, the small-animal object on a rotating stage, and an imaging detector. The source-to-object and object-to-detector distances are adjusted for the preferred contrast mechanism. Two different liquid-metal-jet sources are used, one circulating a Ga/In/Sn alloy and the other an In/Ga alloy for higher penetration through thick tissue. Both sources are operated at 40-50 W electron-beam power with {approx}7 {mu}m x-ray spots, providing high spatial resolution in absorption imaging and high spatial coherence for the phase-contrast imaging. Results: High-resolution absorption imaging is demonstrated on mice with CT, showing 50 {mu}m bone details in the reconstructed slices. High-resolution phase-contrast soft-tissue imaging shows clear demarcation of mm-sized tumors at much lower dose than is required in absorption. Conclusions: This is the first application of liquid-metal-jet x-ray sources for whole-body small-animal x-ray imaging. In absorption, the method allows high-resolution tomographic skeletal imaging with potential for significantly shorter exposure times due to the power scalability of liquid-metal-jet sources. In phase contrast, the authors use a simple in-line arrangement to show distinct tumor demarcation of few-mm-sized tumors. This is, to their knowledge, the first small-animal tumor visualization with a laboratory phase-contrast system.

    2007-09-06

    In this thesis, structural, optical as well as electronic properties of self-assembled InAs quantum dots (QD) were studied by means of atomic force microscopy (AFM), photoluminescence (PL), capacitance spectroscopy (CV) and capacitance transient spectroscopy (DLTS). The quantum dots were grown with molecular beam epitaxy (MBE) and embedded in Schottky diodes for electrical characterization. In this work growth aspects as well as the electronic structures of QD were discussed. By varying the QD growth parameters it is possible to control the structural, and thus the optical and electronic properties of QD. Two methods are presented. Adjusting the QD growth temperature leads either to small QD with a high areal density or to high QDs with a low density. The structural changes of the QD are reflected in the changes of the optical and electronic properties. The second method is to introduce a growth interruption after capping the QD with thin cap layers. It was shown that capping with AlAs leads to a well-developed alternative to control the QD height and thus the ground-state energies of the QD. A post-growth method modifying the QD properties ist rapid thermal annealing (RTA). Raising the RTA temperature causes a lifting of the QD energy states with respect to the GaAs band edge energy due to In/Ga intermixing processes. A further main part of this work covers the emission processes of charge carriers in QD. Thermal emission, thermally assisted tunneling, and pure tunneling emission are studied by capacitance transient spectroscopy techniques. In DLTS experiments a strong impact of the electric field on the activation energies of electrons was found interfering the correct determination of the QD level energies. This behaviour can be explained by a thermally assisted tunneling model. A modified model taking the Coulomb interaction of occupied QD into account describes the emission rates of the electrons. In order to avoid several emission pathes in the experiments

    Dinitrogen (N2)-fixing trees in the Fabaceae fulfill a central role in tropical rainforests by supplying nitrogen from the atmosphere, yet whether they will support a forest CO2 sink in the future by alleviating nitrogen limitation may depend on whether and how they are controlled by local environmental conditions. Theory predicts that soil nutrients govern the function of N2 fixers, yet there have been no large-scale field-based tests of this idea. Moreover, recent findings indicate that N2-fixing species behave differently in biogeochemical cycles, suggesting that any environmental control may differ by species, and that the diversity of N2-fixing trees may be critical for ensuring tropical forest function. In this talk, we will use the RAINFOR dataset of 108 (~1.0 ha) lowland tropical rainforest plots from across the Amazon Basin to test whether the abundance and diversity of N2-fixing trees are controlled by soil nutrient availability (i.e., increasing with phosphorus and decreasing with nitrogen), or if fixer abundance and diversity simply follow the dynamics of all tree species. We also test an alternative - but not mutually exclusive - hypothesis that the governing factor for fixers is forest disturbance. Results show a surprising lack of control by local nutrients or disturbance on the abundance or diversity of N2 fixers. The dominant driver of fixer diversity was the total number of tree species, with fixers comprising 10% of all species in a forest plot (R2 = 0.75, linear regression). When considering the dominant taxa of N2 fixers (Inga, Swartzia, Tachigali) alone, environmental factors (nitrogen, phosphorus and disturbance) became important and clearly governed their abundance. These taxa, which contain >60% of N2-fixing trees in the data set, appear to have evolved to specialize in different local environmental conditions. The strong biogeochemistry-by-biodiversity interaction observed here points to a need to consider individual species or taxa of N2

    Full Text Available Meditatons on the divine liturgy: boundaries of the theatricality in the creative work of Nikolay GogolInga VidugirytėSummary The purpose of the present article is to demonstrate the theatricality of Gogol’s Meditations on the Divine Liturgy. Theatricality is “the language of theatre as art”, as Jurij Lotman has stated. Phillis Hartnoll points out three aspects, viz. an actor, a dialogue, and a spectator, that separate theatre from its origins – the ritual. The birth of the spectator seems to Lotman and to Boris Uspenskij to be the decisive factor to establish a situation of the performance. The visuality of the performance is the main feature of theatre as art.There are three presumptions Gogol has about liturgy: (1 liturgy is a dramatic form of the evangelical plot, (2 the forms of worship in liturgy are so perfect that watching them is enough to understand the meaning of the ritual, (3 in liturgy, it is possible to achieve the unity of souls and feelings of all participants of the ritual. Gogol presents liturgy as performance. The narrative is based on separate scenes with clearly marked beginnings and ends. Gogol even renders intonations of dialogues between a priest and a deacon. The motif of performing distinguishes Gogol’s work from his predecessors.The only point of view in the text is from the outside. The narrator is one of the spectators of liturgical performance. On the other hand, the narrator is also a participator of the worship. Gogol shows the effect the performance makes on people and also renders their praying. Taking the sacrament is described as catharsis and in the same terms as Aristotle has done, viz. the horror and the purging. So even at this moment the theatrical nature of liturgy is retained.In the context of the Gogol’s discourse of theatre, liturgy seems to be the ideal performance. One can presuppose that the writer’s wish to explain the role of the theatre has ended with describing the most

    2007-01-01

    In this thesis, structural, optical as well as electronic properties of self-assembled InAs quantum dots (QD) were studied by means of atomic force microscopy (AFM), photoluminescence (PL), capacitance spectroscopy (CV) and capacitance transient spectroscopy (DLTS). The quantum dots were grown with molecular beam epitaxy (MBE) and embedded in Schottky diodes for electrical characterization. In this work growth aspects as well as the electronic structures of QD were discussed. By varying the QD growth parameters it is possible to control the structural, and thus the optical and electronic properties of QD. Two methods are presented. Adjusting the QD growth temperature leads either to small QD with a high areal density or to high QDs with a low density. The structural changes of the QD are reflected in the changes of the optical and electronic properties. The second method is to introduce a growth interruption after capping the QD with thin cap layers. It was shown that capping with AlAs leads to a well-developed alternative to control the QD height and thus the ground-state energies of the QD. A post-growth method modifying the QD properties ist rapid thermal annealing (RTA). Raising the RTA temperature causes a lifting of the QD energy states with respect to the GaAs band edge energy due to In/Ga intermixing processes. A further main part of this work covers the emission processes of charge carriers in QD. Thermal emission, thermally assisted tunneling, and pure tunneling emission are studied by capacitance transient spectroscopy techniques. In DLTS experiments a strong impact of the electric field on the activation energies of electrons was found interfering the correct determination of the QD level energies. This behaviour can be explained by a thermally assisted tunneling model. A modified model taking the Coulomb interaction of occupied QD into account describes the emission rates of the electrons. In order to avoid several emission pathes in the experiments

    Ongoing research into the evolution of fishes in the lower Congo River suggests a close tie between diversity and hydraulic complexity of flow in the channel. For example, fish populations on each side of the rapids at the head of the lower Congo are within 1.5 km of one another, a distance normally allowing for interbreeding in river systems of comparable size, yet these fish populations show about 5% divergence in their mitochondrial DNA signatures. The proximal reason for this divergence is hydraulic complexity: the speed and turbulence of water moving through the thalweg is a barrier to dispersal for these fishes. Further examination of fish diversity suggests additional correlations of evolutionary divergence of fish clades in association with geomorphic and hydraulic features such as deep pools, extensive systems of rapids, alternating sections of fast and slow current, and recurring whirlpools. Due to prohibitive travel costs, limited field time, and the large geographic domain (approximately 400 river km) of the study area, we undertook a nested set of remote sensing analyses to extract habitat features, geomorphic descriptors, and hydraulic parameters including channel forming velocity, depth, channel roughness, slope, and shear stress. Each of these estimated parameters is mapped for each 1 km segment of the river from the rapids described above to below Inga Falls, a massive cataract where several endemic fish species have been identified. To validate remote sensing estimates, we collected depth and velocity data within the river using gps-enabled sonar measurements from a kayak and Doppler profiling from a motor-driven dugout canoe. Observations corroborate remote sensing estimates of geomorphic parameters. Remote sensing-based estimates of channel-forming velocity and depth were less than the observed maximum channel depth but correlated well with channel properties within 1 km reach segments. This correspondence is notable. The empirical models used

    The ternary A 1 B 3 C 3 6 compounds are perspective materials for creation on their base the high effective transformers of solar energy, photodetectors with the high efficiency. In this paper the results of the investigation of the short-circuit current dependence on the wavelength and influence of the γ-ray radiation on the electrical properties of the p-type CuGaSe 2 crystals have been reported. The (Co 60 ) with the quantum energy of 1.25 MeV was used as a g amma - ray source. The CnGaSe 2 crystals were obtained by the chemical transport reactions. Iodine crystalline was used as a transporter. The lattice parameters were determined by the X-ray method as a=5.607 Angstroms, c=10.99 Angstroms, c/a=l.96. The In-Ga eutectic contacts were put on the nature surfaces of the films for the earring out the measurements. The films with the ρ=10 2 -10 7 Ω·cm resistivity were investigated. The films one can divide into two group: low resistance ρ=10 2 -10 3 Ω·cm and high resistance ρ=10 5 -10 7 Ω·cm films. The inverse of the current is observed in the I ns ∼f(λ) short-circuit current dependence with the wavelength in the low resistance films. The inverse is not observed in the high resistance ones. The measurement of the resistivity of the CuGaSe 2 films radiated by γ-ray radiation were carried out at 77 K. The resistivity of the low-resistance films under the radiation up to 50 p/s changes slowly, then increases sharply and achieves the value ρ=10 6 Ω·cm. Beginning from 300 p/s the resistivity decreases. Further increasing of the power doesn't influence on the resistivity. The resistivity of the high resistance films decreases up to 10 6 Ω·cm at 100 p/s with the increasing of the dose of γ-ray radiation and then doesn't change with the radiation dose. The investigation of the temperature dependence of the resistivity in the low resistance films previously radiated under the γ-ray radiation showed that increasing of the γ-ray radiation doesn't almost

    Highlights: • Amorphous IGZO films are obtained by sputtering at various substrate temperatures. • Higher substrate temperatures lead to lower band gaps and high refractive index. • High temperature results in lower resistivity and larger charge carrier content. • Increased oxygen vacancies attributes to the reduced band gap. • Increased In content in IGZO films leads to the improved electrical properties. - Abstract: The effects of substrate temperature (T{sub s}) on the electrical and optical properties of amorphous InGaZnO thin films deposited by sputtering have been investigated. As T{sub s} increased from RT to 400 °C, all the films remained amorphous, the transmission in the visible region increased from 92.8% to 93.54%, and the band gap decreased from 3.42 eV to 3.31 eV. Based on Cauchy–Urbach model, the optical properties of all samples were analyzed by spectroscope ellipsometry (SE) and increase in refractive index has been detected with the increase in T{sub s}. Results of Hall measurement showed that substrate temperature have remarkable influence on the resistivity (ρ), carrier concentration (n), and carrier mobility (μ) of IGZO films. As T{sub s} increased from RT to 400 °C, ρ decreased from 46.6 to 0.24 Ω cm, and then increased to 1.11 Ω cm at T{sub s} of 400 °C, and n increase from 5.67 × 10{sup 15} to 7.33 × 10{sup 18} cm{sup −3}. Investigation of X-ray photoelectron spectroscopy (XPS) indicated that as T{sub s} increased, an O 1s component representing the oxygen vacancies increased in amount and that the intensity ratio of In/Ga increased but that of Zn/Ga decreased. The analysis suggests that the increase of oxygen vacancies could explain the increase in n and reduction in ρ and that the compositional change could explain the change of E{sub g}.

    Intrinsic zinc oxide films, normally deposited by radio frequency (RF) sputtering, are fabricated by direct current (DC) sputtering. The oxygen-deficient targets are prepared via a newly developed double crucible method. The 800-nm-thick film obtaines significantly higher carrier mobility compareing with that of the 800-nm-thick ZnO film. This is achieved by the widely used RF sputtering, which favors the prevention of carrier recombination at the interfaces and reduction of the series resistance of solar cells. The optimal ZnO film is used in a Cu (In, Ga) Se2 (CIGS) solar cell with a high efficiency of 11.57%. This letter demonstrates that the insulating ZnO films can be deposited by DC sputtering from oxygen-deficient ZnO targets to lower the cost of thin film solar cells.%Intrinsic zinc oxide films,normally deposited by radio frequency (RF) sputtering,are fabricated by direct current (DC) sputtering.The oxygen-deficient targets are prepared via a newly developed double crucible method.The 800-nm-thick film obtaines significantly higher carrier mobility compareing with that of the 800-nm-thick ZnO film.This is achieved by the widely used RF sputtering,which favors the prevention of carrier recombination at the interfaces and reduction of the series resistance of solar cells.The optimal ZnO film is used in a Cu (In,Ga) Se2 (C1GS) solar cell with a high efficiency of 11.57%.This letter demonstrates that the insulating ZnO films can be deposited by DC sputtering from oxygen-deficient ZnO targets to lower the cost of thin film solar cells.High resistance transparent intrinsic zinc oxide (i-ZnO)thin film has been widely nsed as the front electrode in transparent electronics and photovoltaic devices because of its low cost and nontoxicity.Owing to its unique characteristics of high transparency and adjustable resistivity in a certain range,the use of i-ZnO thin films as diffusion barrier layers of a-Si/μc-Si,CdTe,and CIGS thin-film solar cells has been advantageous

    Full text: The A I B III C IV semiconducting compounds are of interest for semiconducting devising. In particular the presence of the birefringence makes the compounds as a perspective materials for using in nonlinear optical transformers. Besides, the complex generation-recombination processes in these compounds are due to the local states in the band gap, which is also due to the complex chemical structure of these compounds. In this report the results of the influence of γ-radiation on the short circuit current in CuGaSe 2 are presented. The Co 6 0 with the quantum energy of 1.25 MeV was a source of radiation. The resistance was 10 2 kΩ at 300 K. The In-Ga eutectic was used as a contact. The measurements have been carried out at 77 K. The electrometer B7-30 was used for the short circuit current measurements, sensitivity of which is 10 -15 A. The intensity of γ-rays was 20 R/s, durability of radiation was 15 min. The spectrometer SPM-2 was used as a source of radiation of monoxrmator light. The spectral dependence of short circuit current of non radiated CuGaSe 2 crystal has a maximum at λ=700 nm (0.77 eV) with the half width of 0.26 eV. The maximum of short circuit current is in good agreement with the value 1.8 eV at 300 K. That is why one can assume that observed peak in J sc ∼∼f(λ) dependence with the maximum at 1.77 eV is due to electronic transitions from the valence band to conduction band. After radiation of CuGaSe 2 crystal new maximum is observed in the spectral dependence of short circuit current at λ=770 nm (1.61 eV) at 77 K. Splitting between the peaks is 0.13 eV. The appearance of the second peak maybe is due to the formation of radiation defects of acceptor type, which are located for 0.13 eV above than the top of valence band. The peak at 1.59 eV, which is due the donor-acceptor recombination, is observed in photoluminescence spectra. It is assumed that, Se vacancy forms the donor levels, Cu vacancy -acceptor levels

  3. Effects of experimental nitrogen fertilization on planktonic metabolism and CO2 flux in a hypereutrophic hardwater lake.

    Full Text Available Hardwater lakes are common in human-dominated regions of the world and often experience pollution due to agricultural and urban effluent inputs of inorganic and organic nitrogen (N. Although these lakes are landscape hotspots for CO2 exchange and food web carbon (C cycling, the effect of N enrichment on hardwater lake food web functioning and C cycling patterns remains unclear. Specifically, it is unknown if different eutrophication scenarios (e.g., modest non point vs. extreme point sources yield consistent effects on auto- and heterotrophic C cycling, or how biotic responses interact with the inorganic C system to shape responses of air-water CO2 exchange. To address this uncertainty, we induced large metabolic gradients in the plankton community of a hypereutrophic hardwater Canadian prairie lake by adding N as urea (the most widely applied agricultural fertilizer at loading rates of 0, 1, 3, 8 or 18 mg N L-1 week-1 to 3240-L, in-situ mesocosms. Over three separate 21-day experiments, all treatments of N dramatically increased phytoplankton biomass and gross primary production (GPP two- to six-fold, but the effects of N on autotrophs plateaued at ~3 mg N L-1. Conversely, heterotrophic metabolism increased linearly with N fertilization over the full treatment range. In nearly all cases, N enhanced net planktonic uptake of dissolved inorganic carbon (DIC, and increased the rate of CO2 influx, while planktonic heterotrophy and CO2 production only occurred in the highest N treatments late in each experiment, and even in these cases, enclosures continued to in-gas CO2. Chemical effects on CO2 through calcite precipitation were also observed, but similarly did not change the direction of net CO2 flux. Taken together, these results demonstrate that atmospheric exchange of CO2 in eutrophic hardwater lakes remains sensitive to increasing N loading and eutrophication, and that even modest levels of N pollution are capable of enhancing autotrophy and CO

    Aim of this thesis was to apply the analytical methods of the scanning transmission electron microscopy to the study of self-organized In(Ga)As quantum structures. With the imaging methods Z contrast and bright field (position resolutions in the subnanometer range) and especially with the possibilities of the quantitative chemical EELS analysis of the scanning transmission electron microscope (STEM) fundamental questions concerning morphology and chemical properties of self-organized quantum structures should be answered. By the high position resolution of the STEM among others essentail morphological and structural parameters in the growth behaviour of 'dot in a well' (DWell) structures and of vertically correlated quantum dots (QDs) could be analyzed. For the optimization of DWell structures samples were studied, the nominal InAs-QD growth position was directedly varied within the embedding InGaAs quantum wells. The STEM offers in connection with the EELS method a large potential for the chemical analysis of quantum structures. Studied was a sample series of self-organized InGaAs/GaAs structures on GaAs substrate, the stress of which was changed by varying the Ga content of the INGaAs material between 2.4 % and 4.3 %.

These concentrations are higher than those observed in the rain water. It is observed a great variability in the amount of the chemical elements for the different shade trees, which is related to the species used for shading. In relation to pH, the foliage washing water (through fall) shows an average value of 6.7 for the ecosystems in study; the lowest values in ph appear for the association of the coffee with the eucalyptus and the pine, pH of 6.3 and - 6.4 respectively.

    The objective of this study was to determine the solubility parameters (rapid and slow dissolution rates, rapid and slow dissolution fractions) metal particles present in a pile of sludge accumulated under exposure to weathering from the Cia Mercantil Inga, located at the Ilha da Madeira, Sepetiba Bay, Rio de Janeiro. Plant samples collected in the neighboring of the pile and bioindicators placed in the region and collected after some months indicated that the inhabitants of Ilha da Madeira have been exposed to trace elements such zinc, cadmium, mercury and lead, produced during the processing of zinc minerals (hemimorphite - Zn{sub 4}(OH){sub 2}Si{sub 2}O{sub 7}.H{sub 2}O, and willemite - Zn{sub 2}SiO{sub 4}). A static dissolution test in vitro was used to determine the solubility parameters using a simulated lung fluid (SLF), on a time basis ranging from 10 min to 1 year. The metal concentrations in the sludge samples and in the SLF were determined using Particle Induced X-rays Emission (PIXE). In conclusion, this study confirms the harmful effects on the neighboring population of the airborne particles containing these metals that came from the sludge. The solubility parameters obtained for Zn, Cd, Cr, Ni and Mn present in the rapid dissolution fraction in SLF were 0.945; 0.473; 0.226; 0.300 and 0.497, respectively, and the corresponding times for half life of dissolution of the rapid fraction were f{sub r} = 2.082 days; f{sub r} = 0.09 days; f{sub r} = 0.37 days; f{sub r} = 0.332 days ad f{sub r} = 0.99 days; for the slow dissolution fraction times were f{sub r} = 146.95 days; f{sub r} = 63 days; f{sub r} = 86.64 days; f{sub r} = 79.66 days and f{sub r} = 59.84 days. These values indicate that these metals present a moderate absorption level in SLF, and may be classified as M type, according to the International Commission on Radiological Protection (ICRP). The use of solubility parameters allowed a better description of the kinetic behaviour of the sludge in

    The objective of this study was to determine the solubility parameters (rapid and slow dissolution rates, rapid and slow dissolution fractions) metal particles present in a pile of sludge accumulated under exposure to weathering from the Cia Mercantil Inga, located at the Ilha da Madeira, Sepetiba Bay, Rio de Janeiro. Plant samples collected in the neighboring of the pile and bioindicators placed in the region and collected after some months indicated that the inhabitants of Ilha da Madeira have been exposed to trace elements such zinc, cadmium, mercury and lead, produced during the processing of zinc minerals (hemimorphite - Zn 4 (OH) 2 Si 2 O 7 .H 2 O, and willemite - Zn 2 SiO 4 ). A static dissolution test in vitro was used to determine the solubility parameters using a simulated lung fluid (SLF), on a time basis ranging from 10 min to 1 year. The metal concentrations in the sludge samples and in the SLF were determined using Particle Induced X-rays Emission (PIXE). In conclusion, this study confirms the harmful effects on the neighboring population of the airborne particles containing these metals that came from the sludge. The solubility parameters obtained for Zn, Cd, Cr, Ni and Mn present in the rapid dissolution fraction in SLF were 0.945; 0.473; 0.226; 0.300 and 0.497, respectively, and the corresponding times for half life of dissolution of the rapid fraction were f r = 2.082 days; f r = 0.09 days; f r = 0.37 days; f r = 0.332 days ad f r = 0.99 days; for the slow dissolution fraction times were f r = 146.95 days; f r = 63 days; f r = 86.64 days; f r = 79.66 days and f r = 59.84 days. These values indicate that these metals present a moderate absorption level in SLF, and may be classified as M type, according to the International Commission on Radiological Protection (ICRP). The use of solubility parameters allowed a better description of the kinetic behaviour of the sludge in the human body and, therefore, a better evaluation of the worker’s risk to

Twelve 50 m x 200 m plots were established in a 12 ha sample area, in which all trees CPH (circumference 1.3 m above ground > 157.5 cm were recorded; twelve 50 m x 50 m subplots in which individuals 94.2 cm ≤ CAP < 157.1 cm were recorded; and twelve 50 m x 25 m subplots for measuring individuals 31.4 cm ≤ CAP < 94.2 cm. A total of 1227 trees from 175 species and 38 families were recorded in the forest sample. Higher number of species was found in Fabaceae and genus Inga was the richest. Diversity Shannon index (H' was 4.39 and Evenness index (J was 0,85. The analysis of VIA showed that remain forest keeps a stock of timber and non-timber potential species for using by the community. Carapa guianensis, Caryocar villosum, Brosimum parinarioides, Aniba canellila, Bowdichia virgilioides and Andira surinamensis can be suggested to be removed from the timber harvesting list, thus improving community economic return. Manilkara huberi and Carapa guianensis were the species with more expressive timber and non-timber uses, respectively, according to the present market and the potential of known uses; so it will be very interesting that these characteristics can be taking into consideration during the elaboration of plans and management of the forest.

O local de estudo é conhecido como Mata do Galego, possui cerca de 77 ha e está localizado a 21°29'S e 44°55'W, às margens do rio Ingaí. A amostragem florística foi realizada em parcelas e também em caminhadas pela floresta. Todo o material coletado foi identificado e incorporado ao Herbário ESAL, da Universidade Federal de Lavras. O levantamento estrutural foi realizado por meio de amostragem sistemática, em 32 parcelas de 20 × 20m, distribuídas em três transeções, da margem do rio até a borda da mata. Nas parcelas, foram amostrados todos os indivíduos arbóreos, vivos, com circunferência à altura do peito (CAP ≥ 15,5 cm. As variáveis químicas e físicas do solo foram obtidas das análises de amostras superficiais de solo (0-20 cm de cada parcela. No levantamento florístico foram amostradas 201 espécies, 129 gêneros e 57 famílias. As famílias com maior riqueza foram Myrtaceae, Lauraceae, Fabaceae Faboideae, Rubiaceae, Euphorbiaceae e Fabaceae Mimosoideae.

O delineamento experimental utilizado foi o de blocos casualizados completos com dois tratamentos (Aspidosperma spp., 32 repetições com parcelas lineares e 4 plantas por parcela. Aos 15 anos de idade foram mensurados diâmetro à altura do peito – DAP, altura de total – ALT e sobrevivência – SOB e os parâmetros genéticos foram estimados pelo programa Selegen. A espécie cylindrocarpon apresentou maior desenvolvimento nos caracteres de crescimento (DAP e ALT quando comparada com A. polyneuron. A taxa de sobrevivência foi de 71% demostrando boa adaptabilidade para ambas as espécies ao local de implantação do experimento. A acurácia foi alta, sugerindo maior confiabilidade das análises estatísticas. A herdabilidade foi moderada, indicando considerável controle genético nas espécies quando se observa que o coeficiente de determinação dentro de parcela foi menor que 10% para ALT e DAP, mostrando que as parcelas lineares são homogêneas, ou seja, o delineamento experimental adotado foi eficiente. Portanto, a ausência do uso de estrutura de progênies nas populações de Aspidosperma spp. estudadas não impossibilitou que fossem obtidas informações relevantes sobre as populações naturais de Aspidosperma, porém vale ressaltar que é de suma importância que novas coletas de sementes sejam realizadas para um estudo com base em teste de progênies.

Verificou se que o substrato não tratado apresentava alto teor de Mn nas frações fitodisponíveis, valores esses tóxicos para as espécies estudadas. Os tratamentos causaram redução nas concentrações de Mn em solução e trocável (frações fitodisponiveis e aumento nas fases mais estáveis. A menor dose de Escória de Aciaria foi suficiente para que ocorresse diminuição nas concentrações de Mn em solução, sendo este efeito evidenciado pelo desenvolvimento das plantas e na maior dose de Escória de Aciaria o crescimento das espécies estudadas foi maior. O Eucalyptus urophylla apresentou maior desenvolvimento e maior extração deste elemento.Currently, there is considerable interest in developing strategies that are efficient and durable in the remediation of soils contaminated with heavy metals.

    Full text: The existence of life on planets such as Mars may depend upon the presence of water. This water may not necessarily be as liquid or crystalline water but may be as interlayer water such as is found in smectitic clays. One group of smectites, relevant to the search for interplanetary life are those which have a high iron content, known as nontronites. Near-IR reflectance spectroscopy has been used to show the presence of water and hydroxyls in these minerals. Three near -IR spectral regions are identified: (a) the high frequency region between 6400 and 7400 cm -1 attributed to the first overtone of the hydroxyl stretching mode (b) the 4800-5400 cm -1 region attributed to water combination modes and (c) the 4000-4800 cm -1 region attributed to the combination of the stretching and deformation modes of the FeFeOH units of nontronite. Two types of hydroxyl groups were identified using near-IR spectroscopy: hydroxyl units coordinated to the iron and hydroxyl groups from water in the nontronite structure. The first hydroxyls are characterised by several bands: firstly in the 7055 to 7098 cm -1 region assigned to the first overtone of the AlFeOH stretching unit, secondly in the 6958-6878 cm -1 region attributed to the FeFeOH unit. The overtone of the hydroxyl stretching frequency of water was observed at around 6800 cm -1 . These observations show that nontronites can be a source of water that may support life. Other techniques may also be used to characterise the Martian clays. Techniques such as Raman spectroscopy and emission spectroscopy as well as reflectance spectroscopy come to mind. Smectites including the iron bearing smectites have proved difficult to measure using the techniques of Raman spectroscopy. The use of FT-Raman spectrometers using INGAS detectors has enabled the spectra of a selection of high iron-bearing smectites and nontronites to be measured. Low intensity hydroxyl-stretching Raman bands were found at 3436 and 3355 cm -1 and are

A perda de massa nos sacos de decomposição foi de 30,1 % para Acacia angustissima, de 32,7 % para Sclerolobium paniculatum, de 33,9 % para Inga edulis e para a vegetação secundária, de 45,2 % para Acacia mangium e de 63,6 % para Clitoria racemosa. Foi observada imobilização de N e P em todos os tratamentos, sendo a mineralização do N negativamente correlacionada com o fenol, razão C/N, razão (lignina + fenol/N, razão fenol/P e o conteúdo de N nos sacos de liteira. Depois de 362 dias de incubação no campo, 3,3 % de K, 32,2 % de Ca e 22,4 % de Mg permaneceram no material em decomposição. Os resultados evidenciaram que a baixa qualidade mineral e a alta quantidade de carbono orgânico e aplicado como cobertura morta podem limitar a quantidade de energia disponível para os microrganismos resultando em uma competição por nutrientes com as plantas agrícolas.

    health of populations using these fuels. More than 153,000 people die each year from household air pollution in the SADC member states, caused mainly by burning of solid fuels for cooking. Energy security was a key issue driving the formation of SADC in 1980, and it remains critical today. However, the motivation has changed, and the main concern now is ensuring that SADC member states are linked by reliable and secure interconnections that permit the exchange of power between the northern, hydro-dominated region and the southern, fossil fuel-dominated region. More than 6,000 MW of new trans-border connections are anticipated to be completed in 2014-15 alone. Infrastructure development, which includes new generation capacity as well as transmission and distribution capacity, is expected to increase significantly in the next 5-10 years. According to a 2015 update of the RISDP, SADC will have a total investment portfolio for electricity generation of between USD 114 billion and USD 233 billion for the period 2012-2027. The related transmission investment costs to support new generation capacity are estimated at USD 540 million, not including already planned transmission inter-connectors and national backbone lines. On the financing side, several major hydropower projects are nearing financial closure. Planning for the 4,800 MW Inga III project in the DRC is nearly finalised as Eskom, the South African utility, has agreed to off-take 2,500 MW of the energy generated, and preliminary agreement has been reached among the investors for the proposed Mphanda Nkuwa dam in Mozambique

    Full Text Available Long term applications of leguminous green mulch could increase mineralizable nitrogen (N beneath cupuaçu trees produced on the infertile acidic Ultisols and Oxisols of the Amazon Basin. However, low quality standing cupuaçu litter could interfere with green mulch N release and soil N mineralization. This study compared mineral N, total N, and microbial biomass N beneath cupuaçu trees grown in two different agroforestry systems, north of Manaus, Brazil, following seven years of different green mulch application rates. To test for net interactions between green mulch and cupuaçu litter, dried gliricidia and inga leaves were mixed with senescent cupuaçu leaves, surface applied to an Oxisol soil, and incubated in a greenhouse for 162 days. Leaf decomposition, N release and soil N mineralization were periodically measured in the mixed species litter treatments and compared to single species applications. The effect of legume biomass and cupuaçu litter on soil mineral N was additive implying that recommendations for green mulch applications to cupuaçu trees can be based on N dynamics of individual green mulch species. Results demonstrated that residue quality, not quantity, was the dominant factor affecting the rate of N release from leaves and soil N mineralization in a controlled environment. In the field, complex N cycling and other factors, including soil fauna, roots, and microclimatic effects, had a stronger influence on available soil N than residue quality.Aplicações a longo prazo de leguminosas como adubo verde podem aumentar o nitrogênio (N mineralizável sob árvores de cupuaçu em solos pouco férteis e ácidos (Ultisols e Oxisols da Bacia Amazônica. Entretanto, a baixa qualidade da liteira de cupuaçu pode influênciara liberação de N do adubo verde e a mineralização deste no solo. Neste estudo foram comparados o N mineral, N total, e o N da biomassa microbiana sob árvores de cupuaçu cultivadas em dois sistemas

    Since 1957, study and research on the' production of radiation loops has been going on in the Soviet Union. Methods for calculating such systems were worked out and the possibilities of various gamma carriers examined. Indium alloy loops, liquid at room temperature, were first selected for practical experiment. The behaviour of two eutectic indium alloys was studied in relation to certain constructional materials and at the beginning of 1960 the first test indium-gallium loop was operated. Further work led to the installation of a model indium-gallium loop in the IRT reactor of the Georgian SSR Academy of Sciences with an irradiation source activity of 100 g Ra equivalent and a test In-Ga-Sn loop in a channel of the IRT reactor at the Institute of Atomic Energy, USSR Academy of Sciences. Finally in 1962, a pilot In-Ga-Sn loop for semi-industrial radiation processes was put into service in the IRT reactor of the Latvian SSR Academy of Sciences; its maximum irradiation source activity was 30 000 g Ra equivalent. The paper has the following sections: (1) ''Radiation loop calculation'', summarizing the work done on the computation techniques involved. (2) ''A model In-Ga radiation loop for the IRT-2000 reactor in Tbilisi'', describing the loop in operation. (3) ''An In-Ga-Sn radiation loop for the Latvian SSR Academy of Sciences IRT Reactor'', describing the loop in operation. (4) ''Possibilities of further radiation loop development'', describing experiments and systems and giving calculations on the basis of which it is considered possible to build hard manganese and mobile liquid indium-alloy loops.

    PUFA och särskilt de sk. omega-3 PUFA. En tränad smakpanel bedömde att kött från renar som utfodrats med kommersiellt renfoder smakade mer lever och sött och hade mindre bismaker (som t.ex. gräs, vilt och ren jämfört med kött från naturbetande renar. I en konsumentundersökning av samma typer av renkött föredrog 50 procent av konsumenterna beteskött och 50 procent föredrog kött från utfodrade renar.Den senaste forskningen har studerat nya foderblandningar där ingredienser som linfrö och fiskmjöl har utvärderats. Linfrökaka som tillsats i renpellets gav köttet en fettsammansättning som påminde om den i kött från naturbetande renar, d.v.s. köttet innehöll mer PUFA än kött från renar som utfodrats med normala pellets. I försök där fiskmjöl har använts som proteintillskott i renfoder visades ett bra foderutnyttjande och god tillväxt hos renarna och inga negativa effekter på renköttets smak kunde påvisas varken av en tränad smakpanel eller vid en konsumentundersökning. Fettsammansättningen i köttet påverkades marginellt av tillsatsen av fiskmjöl jämfört med normalfodret baserat på sojaprotein. Kött från kontrollgruppen av naturbetande renar hade det signifikant högsta innehållet av PUFA. Kunskapen om de olika faktorer som påverkar renköttets kvalitet har ökat påtagligt under de senaste 25 åren, men fortfarande saknas en del fakta när det gäller sambanden mellan produktionssystem, slakthantering och köttkvalitet.

    (b: Adagio tonada el Tuppamaro de caxamarca"- could be related to the events of Cajamarca leading to the capture and death of Inca Atahualpa. The same volume II contains two other plates depicting the beheading of the Inca: "Danza de la degollación del Inga E 172; E173". Ifthis were the case these two tunes could be the only remaining musical fragments of the theatrical performances mentioned above. As a result of the analysis of these two scores we discovered that they could bear a relationship with other scores of the same codex on the basis of musical or text analogies which could be traced back to the tragic events of Cajamarca. These scores are the following: "E. 191, Magestuoso Cachua la Despedida de Guamachuco"; "E. 190 Allegro tonada la brugita para cantar de Guamachuco" and "E. 187. Andantino Tonada ElDiamante, para baylar de Chachapoyas". However our main interest was not to ascertain whether some "tonadas" of the codex could have been part of a theatrical performance of the capture and death of Atahualpa at the end of the colonial period. Indeed we are interested in interpreting these chants as bearing signs of a colonial discourse in two different aspects. On the one hand, the reinterpretation of such historical facts as the capture and death of Atahualpa, and on the other the lingering on of Andean codes in the remembrance of certain rituals such as the "ceremonial grieving". For the sake of musical analysis it was established the existence of a mode conceived initially as part of a system of modes of theInca era related to the system of European church modes. We have named this mode as "Inca grieving" and we will consider its relationships with the ceremonial grieving of the times of the incas as well as its role in the transmission of meanings related to the colonial Andean rituals.

These formations represent a rare (archaic? derivational process and they can be used to support the hypothesis of the deverbative origin of suffix ‑styti (Latvian ‑stīt. The proponents of this hypothesis believe that present stems in ‑sta provided bases for some formations in ‑yti (‑o, ‑ė which were later resegmented and gave rise to new suffix ‑styti (‑sto, ‑stė, cf.: lankst‑ýti : liñkst‑a → lank‑stýti : leñk‑ti (Ul’janov 1888, 210; Leumann 1942, 125; Vaillant 1966, 364; Smoczyński 1987, 203.
