Carbon balance modifications in Sphagnum-dominated peat mesocosms invaded by Molinia caerulea

Peatlands are wetlands acting as carbon (C) sink at a global scale. Even if, it represents only 3% of the land area, these specific ecosystems have stored a third of the global soil C. Most peatlands (up to 80%) are located in the northern hemisphere and lie in cool temperate zone in association with waterlogged, nutrient poor conditions and Sphagnum mosses, which limit the activity of the soil decomposers. As a result, in spite of the relative small net ecosystem production in peatlands, the imbalance between the primary production and the decomposition is enough to allow organic matter (OM) accumulation as peat (Bragazza et al., 2009). However, global change are expected to cause a plant community shift in peatlands with an increase of vascular plants (such as graminoids at the detriment of Sphagnum species (Dieleman et al., 2015). Vascular plants invasion in peatlands have mostly been studied through a change of CO2 and CH4 emissions with different plant community composition. In spite of observed C fluxes modification, the role of vascular plant invasion on the C sink balance in peatlands are still to be elucidated. The aim of this study was to investigate how an invading graminoid plants, Molinia caerulea, can affect the C balance of Sphagnum-dominated peatland. CO2 fluxes and CH4 emissions were regularly measured in peat mesocoms during fourteen months and related to biotic and abiotic factor to calculate the annual C budget with and without Molinia caerulea. Twelve peat mesocosms (depth and diameter: 30 cm) were collected in March 2015 in La Guette peatland (France). This is an acidic fen invaded by Molinia caerulea, a graminoid plant invading numerous peatlands. The mesocosms were buried outdoor and surrounded with a tarpaulin containing water from the peatland. Air and soil temperature at 5 and 20 cm depth were monitored in each mesocosm. The mesocosms were separated into 2 treatments with 6 containing only Sphagnum rubellum ('Sphagnum' mesocosms) and 6 containing Sphagnum rubellum and Molinia
Optimal Allocation of Active Power Filter On real distribution network for improvement of power quality by use of BBO: A case study

ABSTRACT: According to development of power electronics device, harmonic distortion spread on the network. Thus harmonic is a threat for instrument, network, decreasing of line capacity and etc. Active power ﬁlter (APF) can be employed for harmonic compensation in power systems. In this paper a distorted distribution feeder is considered and analyzed from power quality viewpoint using power analyzer device and simulated in MATLAB-Mfile. Then the size and place of active power filters are determined by use of Biogeography Based Optimization (BBO). The goal of this optimization is minimizing of losses and total harmonic distortion (THD) in feeder by considering economical cost. The performance of the approaches are assessed and appreciated by a case study on the Ghaemshahr-Iran Distribution network. Measurement is done on the city network by power analyzer CA8310. All data was collected on Computer. Then researcher algorithm BBO, it is selected the best place and size for Active power filter. The results show a good performance.
Effect of the tryptone concentration on the calcium carbonate biomineralization mediated by Bacillus cereus

espanolSe evaluaron cinco concentraciones de triptona (0.2%, 0.4%, 0.6%, 0.8% y 1.0%) en procesos de biomineralizacion de carbonato de calcio, utilizando acetato de calcio al 0.5%. Todos los ensayos se hicieron con una cepa de Bacillus cereus, aislada de los jardines de la Universidad Pontificia Bolivariana (Medellin, Antioquia, Colombia). Los experimentos fueron monitoreados con mediciones de pH y analisis mineralogicos de difraccion derayos X (XRD), espectroscopia de infrarrojo con transformada de Fourier (FTIR) y microscopia electronica de barrido (SEM). La vaterita fue el polimorfo predominante en los precipitados despues de 6 dias de proceso. Sin embargo, una proporcion considerablede calcita (por encima de 30%) aparecio cuando la concentracion de triptona fue de 0.4% y menor. Adicionalmente, los experimentos tuvieron una formacion de precipitados similar (entre 3.2 y 3.6 g/L), menos el ensayo con 0.2% de triptona, que presento una baja produccion de carbonato de calcio (1.79 g/L), indicando que una concentracion de triptona menor a 0.4% limitaria el metabolismo bacteriano y la formacion de CO2, necesaria para la produccion de carbonato de calcio. EnglishFive tryptone concentrations (0.2%, 0.4%, 0.6%, 0.8% and 1.0%) were evaluated on calcium carbonate biomineralization processes, using 0.5% of calcium acetate. A culture of Bacillus cereus, isolated from the gardens of The Universidad Pontificia Bolivariana (Medellin, Antioquia, Colombia) was used in all the assays. The experiments were monitored by pH measurements and mineralogical analysesof X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Scanning electronic microscopy (SEM). Vaterite was the predominant polymorph in the precipitates after 6 days of the process. However, a considerable proportion of calcite appeared(above 30%) when the tryptone concentration was 0.4% or below. Additionally, the other experiments had a similar precipitate formation (between 3.2-3.6 g/L) except the assay using 0.2% of tryptone, which presented a low calcium carbonate production (1.79 g/L). A tryptone concentration below 0.4% would limit the bacterial metabolism and CO2formation, necessary for calcium carbonate production.
AGGRESSION AT SCHOOL: BELIEF IN A PERSONAL JUST WORLD AND WELL-BEING OF VICTIMS AND AGGRESSORS

This paper presents the study that apply just world research to the analysis of aggression at school. Based on previous findings that characterize the belief in a just world (BJW) as a valuable resource for maintaining positive well-being and assimilating injustice, the present studies test the hypotheses that: (1) personal BJW is positively correlated with subjective well-being; (2) This relationship holds for victims and aggressors alike. Overall, findings were in line with our hypotheses. The stronger the adolescents’ endorsements of the BJW, the better their well-being. The pattern of results persists when controlled for neuroticism and extraversion. The implications of these results for further studies on aggression, victimization, and well-being are discussed.
Infectious hypodermal and haematopoietic necrosis virus (IHHNV) in a hybrid penaeid prawn from tropical Australia

Chronic low-grade mortalities became epizootic in a batch of Penaeus esculentus hybridised with Penaeus rnonodon prawns In Australia. Histopathological exammation revealed extensive tissue changes in the gills, hypodermis, antenna1 gland, heart, ventral nerve cord, lymphoid organ, haematopoietic tissue, muscle and the connective tissue including the intertubule connective tissue in the hepatopancreas. Infected cells displayed intranuclear Cowdrey type A inclusions with marginated chromatin. The ~nclusions did not stain positively with Feulgen's DNA stain. Electron mlcroscopy showed particles approximately 20 nm in dlameter in the cytoplasm near the nucleus but no virions were observed intranuclearly. All the above characters are diagnostic for infectious hypodermal and haematopoietic necrosis virus (IHHNV). Other viruses that were infecting these prawns included lymphoidal parvovirus (LPV), Plebejus baculovirus (PBV), a haemocytic baculovirus and large icosahedral-shaped virus. This IS the first record of IHHNV in a country that has not imported live prawns and suggests that IHHNV occurs naturally in the Australian Indo-West Pac~flc region.

The impact of capillary instability and furnace operating conditions on the fabrication of drawn metamaterials

Metamaterials are composites containing metal structures imbedded within a dielectric matrix. Their nanoscale structure gives them optical properties that don’t exist in naturally occurring materials. This paper focuses on the issue of PlateauRayleigh instability when fibre drawing technology is used to manufacture such metamaterials. Linear stability analysis can identify the key operating parameters that influence the instability of the metal core as a function of the metal/dielectric combination used in the drawn fibre. To verify these theoretical predictions, a numerical fibre drawing model, developed using commercially available software, is used to examine the nonisothermal drawing of a polymer preform containing a concentric metal core in a cylindrical furnace. All heat transfer modes are included. To determine the external radiative heat flux across the preform surface, a Monte Carlo Ray-Tracing method is coupled with the drawing model to calculate the view factors between the furnace walls and the deforming preform. The impact of the key operating parameters on the drawing instability is numerically investigated with a simplified version of this heat transfer model. Optimized operating conditions that minimize drawing instability are proposed. INTRODUCTION Metamaterials are an ‘artificial’ class of composites that contain a metallic grid structure embedded within a dielectric matrix. Such composites, engineered on the nanoscale, can give properties unavailable in nature [1-2]. The concept of metamaterials has been discussed for over a decade [3]. However, fabricating highly regular composites of dissimilar materials on the scale required presents challenges, especially for those processes that can be scaled-up to produce commercial quantities in a cost-effective manner. Recently, fibre drawing techniques used in the high-volume fabrication of various optical fibres have been adapted to the creation of metamaterials [4]. Figure 1 shows a preform being fed into a furnace and continuously drawn down to fibre under an applied tension. Drawing has the significant advantage over most other micro-fabrication techniques in that the desired structure is created in a macro-scale preform that is then drawn down many orders of magnitude. In drawing a metamaterial, the preform is fabricated either by milling and metal insertion or by stacking together multiple metal-filled capillaries.
Estimating Auction Models from Transaction Prices with Extreme Value Theory

In this paper we reexamine some results recently appeared in the empirical auction literature: we show that, when only transaction prices are observed (Athey-Haile,(2002)), the distribution of private valuations is irregularly identied , in the sense that its estimate does not converge at the usual parametric rate. The sample bias produced by nonparametric estimators will aect all functionals of practical interest. We present here a dierent approach to estimation, theoretically justied by extreme value theory. Compared to existing approaches this approximation method has several advantages: it produces more accurate results, is computationally easy to perform, and does not require strong assumptions about the unobserved distribution of bidders’ valuations.
The Kaleidoscope of the Operative Solutions for Hearing Restoration in Charge Syndrome: A Critical Review

Exclusively full texts, cited in PUBMED and MEDLINE search engines, that contain all the selected keywords “Charge syndrome”, “cochlear implant”, “cochlear implantation”, “bionic ear” and “ear malformation” have been selected to review the literature on surgical bionic hearing restoration in CHARGE syndrome. A total of 20 publications that specifically deal with the topic have been published between January 1999 and February 2017. At least ten main different otologic and oto-neurosurgical approaches have been suggested in bionic fitting. The otologic approaches were aided by a microscope or an endoscope or by a combined technique, with or without mastoidectomy. The review is conclude by proposing a strategy for the surgical bionic treatment of hearing in children with CHARGE syndrome.
A T H E O R Y OF FINITE VISCOELASTICITY A N D N U M E R I C A L ASPECTS

Abstract--Most current models for finite deformation viscoelasticity are restricted to linear evolution laws for the viscous material behaviour. In this paper, we present a model for finite deformation viscoelasticity that utilizes a nonlinear evolution law, and thus is not restricted to states close to the thermodynamic equilibrium. We further show that upon appropriate linearization, we can recover several established models of finite linear viscoelasticity and linear viscoelasticity. The utilization of this model in a computational setting is also addressed and examples are presented to highlight the differences of the proposed model in relation with other available models. © 1998 Elsevier Science Ltd.

Investigation of carbon phase evolutions in titanium nitride-carbon nanocomposites prepared in supercritical benzene with respect to their lithium storage capacity

Titanium nitride-carbon nanocomposites have been synthesized by the reaction of TiCl4 and NaN3 in supercritical benzene medium that also serves as a carbon source. The as-prepared precursor has been subjected to different heat treatments under ammonia and nitrogen atmospheres. The structure and chemical composition of the synthesized TiN-C nanocomposites are studied by X-ray diffraction (XRD) and CHN elemental analysis. Meanwhile, the nature of carbonaceous species and the respective carbon phase transitions during supercritical process and following heat treatments are further investigated by Raman spectroscopy, time of flight secondary ion mass spectrometry (ToF-SIMS), and their charge-discharge characteristics with respect to lithium storage. After 10 h NH3-treatment at 1000 ˚C carbonaceous phase transforms to graphene layered structure. The highly efficient mixed TiN conducting network and the internal defects between G layers induced by nitrogen doping improve rate capability and cycling performance of G sheets and provides a specific capacity of 381 mAh g-1 at charge/discharge (C/D) rate of 0.2 C. The enhanced electrochemical performance of the SIV nanocomposite is mainly due to improving the electronic/ionic conductivity and reducing charge transfer coefficient and increasing electrochemical surface area that are resulted from anchoring of TiN nanoparticles on graphene sheets.
Experimental investigation on streamlines in a 180º sharp bend

One of the most important concerns of hydraulics engineers is predicting erosion at the outer banks of rivers by studying the flow pattern along the bend. Not only are the streamlines in meanders non parallel curved lines, but they are also twisted. To study the streamlines flowing a sharp bend, a 180o sharp bend was constructed at Persian Gulf University in Iran. Three dimensional flow components at different locations of the bend were measured using Vectrino velocim. In this paper, streamlines were drawn and investigated in different longitudinal profiles, cross sections, and plans. The results indicated that the secondary flow strength and size of the vortex formed at the distance of the beginning to the bend apex would increase. The core of central vortex moved away from the inner bank towards central line of the channel by 22%, and to the water surface by 20%. On the contrary, the size of the secondary vortex increased by 15%. In addition, the average of the horizontal angle of the streamlines, vector and the locus of maximum velocity were determined at different levels in the present investigation.
Personality Antecedents of the Vote.

ABSTRACT The purpose of this paper is to investigate the relationship between psychological traits and voting behaviol. Investigated is the thesis that psychological traits are useful concepts for political scieni:ists as predictors of consistency in behavior. Contending that previous trait theory research has been generally unimpressive, the author hypothesizes that traits may be specific to individuals as well as situations. This reform of trait theory is applied to six politically relevant traits: tendermindedness, radicalism-conservatism, F-scale, social desirability, locus of control, and machiavellianism. The criterion variables include 18 measures of electoral and non-electoral participation, ideology and partisanship, including: votes in campus, local, state and national elections, anti-war activity, party identification, political discussions, and attempts to persuade others. Findings indicate that segregating the sample into trait-relevant and trait non-relevant groups is meaningful since predictive power is distinctly enhanced in the trait-relevant groups. In addition, the analysis shows that the 18 criterion items cluster according to trait-predictability in highly interpretable ways. References relating to personality types, psychological studies, and political participation are included. (Author/DB)
Consumer preferences for circus: A cluster approach

Despite its importance, circus has been completely neglected by cultural economics. There are two main reasons for this: first, circus has been considered as a minor performing arts; secondly, quantitative information on circus are di? cult to collect. This paper represents an attempt to fill this gap by analysing the answers based on 268 questionnaires submitted to people attending Acquatico Bellucci circus. Clustering results suggest the existence of a distinct and interpretable two-cluster solution: traditional and enthusiastic circus attendances and contemporary circus attendances.

Krivine realizability for compiler correctness

We propose a semantic type soundness result, formalized in the Coq proof assistant, for a compiler from a simple functional language to SECD machine code. Our result is quite independent from the source language as it uses Krivine's realizability to give a denotational semantics to SECD machine code using only the type system of the source language. We use realizability to prove the correctness of both a call-by-name (CBN) and a call-by-value (CBV) compiler with the same notion of orthogonality. We abstract over the notion of observation (e.g. divergence or termination) and derive an operational correctness result that relates the reduction of a term with the execution of its compiled SECD machine code.
DEVELOPMENT AND VALIDATION OF UV SPECTROPHOTOMETRIC METHOD FOR DETERMINATION OF NEBIVOLOL HYDROCHLORIDE FOLLOWING ICH GUIDLINES AND STUDY OF ITS DEGRADATION PROFILE

A UV-Spectrophotometric method is described for the determination of Nebivolol hydrochloride (NEB). The method is based on the measurement of the absorbance of NEB solution in methanol: water (10:90) at 281 nm. The system obeyed Beer’s law over the concentration range of 5.0- 50.0 μg/mL. The degradation behaviour of NEB was investigated under dry heat treatment, UV-degradation, acid hydrolysis, alkali hydrolysis and oxidation; and found to degrade under acid hydrolysis, alkali hydrolysis and oxidation. The method was applied to the determination of NEB in tablets.
Design of Reverse Curves Adapted to the Satellite Measurements

The paper presents a new method for designing railway route in the direction change area adapted to the Mobile Satellite Measurements technique. The method may be particularly useful in the situations when both tangents cannot be connected in an elementary way using a circular arc with transition curves. Thus, the only solution would be the application of two circular arcs of opposite curvature signs, that is, the use of an inverse curve. It has been assumed that the design of the geometrical layout will take place within an adequate local coordinate system. The solution of the design problem takes advantage of a mathematical notation and concentrates on the determination of universal equations describing the entire geometrical layout. This is a sequential operation involving successive parts of the mentioned layout. This universal algorithm can be easily applied to the computer software which will allow generating, in an automatic way, other geometrical layouts. Then, the choice of the most beneficial variant from the point of obtained trains velocities while minimizing the track axis offsets will be held using the optimization techniques. The current designing methods do not provide such opportunities. The presented method has been illustrated by appropriate calculation examples.

Helminth Communities of Cyprinodon atrorus in the Natural Protected Area of Cuatro Ciénegas, Coahuila, Northern Mexico

Abstract. The helminth fauna of the bolson pupfish Cyprinodon atrorus (Osteichthyes: Cyprinodontidae) consisted of 7 helminth taxa collected from 7 localities of Cuatro Ciénegas, a natural area protected by the Mexican government in Coahuila, northern Mexico. The helminth community is described at the infracommunity and component community levels. The acanthoeephalan Atactorhynchus duranguensis was the most prevalent and abundant species. The remaining species were rare and found at low mean abundance values. The observed species richness, individual parasite abundance, and diversity were low at both component community and infracommunity levels. These findings are similar to those found in other freshwater fish species in the Nearctic part of Mexico; however, our study shows that the number of larval forms, in terms of species richness and abundance, is very low in comparison with previous studies in the area. Isolation of the Cuatro Ciénegas basin from the Bravo River (= Grande River) basins is suggested as the main factor determining the depauperate helminth assemblage. The low number of individual larval stages in this fish species is probably due to the lack of piscivorous birds in the area.
