Abstract (sommario):

En el español coloquial de la Argentina se emplean las locuciones por ahí y ni ahí como índices de modalidad. Sin embargo, apenas existen registros lexicográficos de por ahí como marca de probabilidad y atenuación enunciativa (=a lo mejor) y de ni ahí como refuerzo de la negación (=absolutamente no). Entonces, dentro de un enfoque cognitivo-funcional, intentaré explicar no solo el pasaje de estos giros desde el dominio locativo hasta el de la modalidad, sino también caracterizarlos como índices de modalidad e integrarlos entre los adverbios y formas equivalentes que se deslizan desde el ámbito predicativo hacia una función periférica que repercute sobre el modus oracional. Esta conversión del dominio locativo al modal supone un proceso de subjetivización, lo que se asocia a una serie de cambios formales por los cuales se redirige el significado referencial literal de las locuciones hacia el ámbito de la enunciación.

Abstract (sommario):

En este artículo se presenta un análisis de las formulaciones aproximadas de impedancia interna para el estudio de transitorios de alta frecuencia en cables subterráneos de alta tensión. El análisis se desarrolla en el dominio de la frecuencia y la conversión al dominio del tiempo se realiza utilizando la transformada rápida de Fourier. El cable se modela como una línea de transmisión multiconductora, utilizando análisis modal y la teoría de redes de dos puertos. Las formulaciones aproximadas de impedancia interna que se analizan son las propuestas por Gary y Wedepohl-Wilcox, las cuales son utilizadas en el modelado de líneas de transmisión aérea y subterránea, respectivamente. Para efectuar el análisis se realiza una comparación de las formulaciones aproximadas con el modelo exacto de impedancia interna y se determina el error relativo de cada formulación para los valores reales como para los valores imaginarios. Los resultados muestran que la formulación aproximada propuesta por Gary para el modelado de líneas de transmisión aéreas se puede utilizar en cables subterráneos para analizar fenómenos transitorios electromagnéticos de alta frecuencia con resultados aceptables. Para realizar el estudio comparativo de las formulas aproximadas de impedancia interna se propone una serie de casos de estudios en los cuales se determina la magnitud del voltaje transitorio, el tiempo de viaje y la atenuación de la onda en líneas monofásicas subterráneas utilizando diferentes longitudes.

Abstract (sommario):

ABSTRACT Conversion between duplicated genes limits their independent evolution. Models in which conversion frequencies decrease as genes diverge are examined to determine conditions underwhich genes can "escape" further conversion and hence escape from a gene family. A review of results from various recombination systems suggests two classes of sequence-dependence models: (1) the "k-hit" model in which conversion is completely inactivated by a few (k) mutational events, such as the insertion of a mobile element, and (2) more general models where conversion frequency gradually declines as genes diverge through the accumulation of point mutants. Exact analysis of the k-hit model is given and an approximate analysis of a more general sequence-dependent model is developed and verified by computer simulation. If ´ is the per nucleotide mutation rate, then neutral duplicated genes diverging through point mutants are likely to escape conversion provided 2µ/λ >> 0.1, where λ is the conversion rate between identical genes. If 2µ/λ << 0.1, the expected number of conversions before escape increases exponentially so that, for biological purposes, the genes never escape conversion. For single mutational events sufficient to block further conversions, occurring at rate ν per copy per generation, many conversions are expected if 2ν/λ << 1, while the genes essentially evolve independently if 2ν/λ >> 1. Implications of these results for both models of concerted evolution and the evolution of new gene functions via gene duplication are discussed.

Abstract (sommario):

Purpose: To analyze the indications, results, and technical problems associated with conversion after endoluminal repair of abdominal aortic aneurysms (AAA) based on a 6-year experience in endovascular grafting. Methods: From August 1994 to May 2000, 520 patients with AAA were deemed candidates for endovascular therapy based on data from contrast-enhanced computed tomography and aortography. Any conversions were performed using an open operation modified according to the indication for conversion, elapsed time from the endoluminal repair, and type of endograft (tube, bifurcated, infra-/suprarenal fixation). Results: Conversion to open repair was required in 37 (7.1%) cases: 23 tube grafts and 14 bifurcated devices. Seventeen (3.2%) conversions occurred at the original operation and 20 (3.8%) were performed secondarily. Indications for primary conversion were mainly device defects (n = 5) or access problems (n = 5), while secondary conversion was primarily owing to type I endoleak (n = 16). The conversion rate was significantly higher in modular devices (5.9%) than unibody designs (1.4%) (p = 0.003). The rate of primary conversions diminished from 10.9% in 1994–1995 to 2.4% between 1996 and 2000, as did the overall mortality rate, from 8.3% in the first time period to 0% in the second for elective conversions, but emergency operations had 40% mortality. Conclusions: Most AAAs require bifurcated devices for complete exclusion, and older model modular grafts have higher conversion rates. Primary conversion decreases as more experience in endoluminal grafting is acquired. Emergency open repair results in a high mortality rate.

Abstract (sommario):

ABSTRACT Gene conversion has been defined as the nonreciprocal transfer of information between homologous sequences. Despite its broad interest for genome evolution, the occurrence of this mechanism in bacteria has been difficult to ascertain due to the possible occurrence of multiple crossover events that would mimic gene conversion. In this work, we employ a novel system, based on cointegrate formation, to isolate gene conversion events associated with crossovers in the nitrogen-fixing bacterium Rhizobium etli. In this system, selection is applied only for cointegrate formation, with gene conversions being detected as unselected events. This minimizes the likelihood of multiple crossovers. To track the extent and architecture of gene conversions, evenly spaced nucleotide changes were made in one of the nitrogenase structural genes (nifH), introducing unique sites for different restriction endonucleases. Our results show that (i) crossover events were almost invariably accompanied by a gene conversion event occurring nearby; (ii) gene conversion events ranged in size from 150 bp to 800 bp; (iii) gene conversion events displayed a strong bias, favoring the preservation of incoming sequences; (iv) even small amounts of sequence divergence had a strong effect on recombination frequency; and (v) the MutS mismatch repair system plays an important role in determining the length of gene conversion segments. A detailed analysis of the architecture of the conversion events suggests that multiple crossovers are an unlikely alternative for their generation. Our results are better explained as the product of true gene conversions occurring under the double-strand break repair model for recombination.

Abstract (sommario):

 Based on yield tables for oak high forest and oak coppice (both first site class) and using assortment tables and assortment prices in the Czech Republic in 2009, a set of variants of conversion of high forest to coppice was simulated. Average annual cut and average gross value of annual cut of such conversions were compared with those of well-established (in terms of the age structure balance) variants of coppice and high forest. Under the existing ratio of assortment prices, established coppice does not reach the gross value yield of high forest. No variant of simulated conversions was more financially profitable than the initial high forest. Furthermore, we found out that a +16.8% increase of the current fuel wood price would counterbalance the mean annual increment of gross value of the best coppice and the worst oak high forest variant. On the other hand, a +164.7% fuel wood price increase would be necessary to counterbalance the mean annual increment of gross value of the worst coppice and the best high forest variants.

Abstract (sommario):

The present paper has introduced an innovative and efficient technique that enables user to hear the contents of text images instead of reading through them. In the current world, there is a great increase in the utilization of digital technology and multiple methods are available for the people to capture images. such images may contain important textual content that the user may need to edit or store digitally. It merges the concept of Optical Character Recognition (OCR) and Text to Speech Synthesizer (TTS). This can be done using Optical Character Recognition with the use of Tesseract OCR Engine. OCR is a branch of AI that is used in applications to recognize text from scanned documents or images. The analyzed text can also be converted to audio format to help visually impaired people hear the content that they wish to know. Text-to-Speech conversion is a method that scans and reads alphabets and numbers that are in the image using OCR technique and convert it into voices. The aim is to study and compare the multiple methods used for STT conversions and to figure out the most efficient technique that can be adapted for the conversion processes. As a result, based on review study it is found that HMM is a statistical model which is most suitable for TTS conversions.

Abstract (sommario):

This paper presents an evaluation of ride comfort performance of a passenger vehicle when converted into an electric vehicle (EV). The evaluations were done using a validated 7 degrees of freedom of vehicle’s ride model. The developed vehicle’s ride model was used to predict the vehicle’s ride behaviours when subjected to random road profiles. The ride model of EV conversion was then integrated with the active suspension system in order to further improve the EV conversion’s ride comfort performance. It was found that the modifications of a normal passenger vehicle into an EV conversion do not affect vehicle’s ride comfort performance significantly, except the conversion changes only the magnitude of vehicle’s vertical displacement, pitch rate and pitch angle responses. However, the integration of an active suspension system in EV conversions ride model was improves the observed responses of EV conversion’s ride comfort performance by overall improvement of 65.7 percents.

Abstract (sommario):

Abstract This paper focuses on the impact of reactant staging on conversion for one single reversible reaction in a two-stage, isothermal, continuous reactor. The analytical expression of global conversion has been derived for a series of two continuously stirred-tank reactors. Improvements in the overall conversion and yield by staging can be obtained for low Damköhler number systems leading to low conversions, when the volumetric flow rate of the staged reactant has a higher value than that of the other one. The example of triolein transesterification involving three reversible reactions in a two-stage plug flow reactor is also studied as a concrete example of a consecutive/parallel reversible reactions system. Results are obtained by using a pseudo-homogeneous model and are compared with those obtained with a heterogeneous model from a previous study.

Abstract (sommario):

Assuming errors of measurement are distributed binomially, this article reviews various procedures for constructing an interval for an individual’s true number-correct score; presents two general interval estimation procedures for an individual’s true scale score (i.e., normal approximation and endpoints conversion methods); compares various interval estimation procedures through a computer simulation study; and provides some practical guidelines for use of the interval estimation procedures. To examine the effects of different types of scale scores, three nonlinearly transformed scale scores are employed. The conditional confidence intervals using conditional standard errors of measurement are recommended over the traditional confidence intervals using the overall standard error of measurement. For raw scores, the score confidence intervals, in general, tend to provide actual coverage probabilities that are closest to the nominal level. Results for scale score intervals seem to favor the endpoints conversion method using the true-score conversions over the normal approximation approach.

Abstract (sommario):

The steam reforming of toluene as a model compound of biomass gasification tar was carried out over Mg and La oxide-promoted Ni-metal oxide/Al2O3 catalysts. Catalysts were prepared by two different methods, co- and sequential impregnation. The findings indicate that conversion of gas products was improved with the use of prepared catalysts especially on syn-gas (H2 and CO) species and the highest conversions were obtained at the reaction temperature of 800°C. LHV’s of product gas when using catalysts at 800°C were over 4 MJ/m3 and ratios of H2 to CO were between 2.49-2.77. For long term test, Carbon and hydrogen conversion to CO and H2 of the catalysts with respect to time on stream in the steam toluene reforming for 480 min were studied. La2O3+MgO+Ni/Al2O3 catalyst revealed the highest and stable conversion rate of closely 50% and 70% for CO and H2, respectively. Whisker carbon species and encapsulating carbon were found on used catalysts after reaction. The La2O3+MgO+Ni/Al2O3 catalyst showed lesser amount of whisker carbon and encapsulating carbon.

Abstract (sommario):

Focusses on how since the arrival of Haitians in South Florida since 1979 many of these increasingly joined and converted to Haitian evangelical Protestant churches, and came to disavow the combined Catholic and Vodou beliefs they adhered to. Author points out how this echoes trends in Haiti since the 1970s of increased conversions to evangelical Protestantism, with these localized/Haitianized Protestant churches later also moving to Florida. She further examines the motivations behind and meanings of these conversions, and argues that poor Haitian migrants construe conversion as a rhetoric and set of behaviours for mastering a model of individual, social, and economic success in the US. At the same time, she shows how this Protestant evangelical practice offers converts an escape route from familial and other obligations and interdependence connected to traditional, transnational domestic and ritual ties, that are also spiritually and magically enforced. Author however indicates that while the pastors model for their flock an assertive, separatist disposition, central to Protestantism's historical appeal, combined with a modern, ascetic approach, underneath this is often an instrumental logic aimed at instant money and private ambition. As these traditionally were illicit rewards of sorcery and magic, the pastors are seen by some as renewed and successful sorcerers. Author further examines the conversions relating these to the moral dialectic from Vodou, known as Guinea and Magic, mediating the conflicts between individualism and community, and gives examples of often pragmatic motivations for conversion. She thus concludes that Haitians' interpretations of their conversions are unique in that they are filled with their cultural concerns, images, and morality.

Abstract (sommario):

This study aims to improve the implementation of models of geospatial information in Web Ontology Language (OWL). Large amounts of geospatial information are maintained in Geographic Information Systems (GIS) based on models according to the Unified Modeling Language (UML) and standards from ISO/TC 211 and the Open Geospatial Consortium (OGC). Sharing models and geospatial information in the Semantic Web will increase the usability and value of models and information, as well as enable linking with spatial and non-spatial information from other domains. Methods for conversion from UML to OWL for basic concepts used in models of geospatial information have been studied and evaluated. Primary conversion challenges have been identified with specific attention to whether adapted rules for UML modelling could contribute to improved conversions. Results indicated that restrictions related to abstract classes, unions, compositions and code lists in UML are challenging in the Open World Assumption (OWA) on which OWL is based. Two conversion challenges are addressed by adding more semantics to UML models: global properties and reuse of external concepts. The proposed solution is formalized in a UML profile supported by rules and recommendations and demonstrated with a UML model based on the Intelligent Transport Systems (ITS) standard ISO 14825 Geographic Data Files (GDF). The scope of the resulting ontology will determine to what degree the restrictions shall be maintained in OWL, and different conversion methods are needed for different scopes.

Abstract (sommario):

I employ a simple game to suggest the effects of information and expectations on bargaining strategies and responses. I make use of members' predispositions in order to identify actors likely to be bargaining. Using administration headcounts, I show that while very few members misrepresent their preferences during the coalition-building process, those who do represent a large proportion of the administration's core supporters, make their misrepresentations unsystematic to avoid a costly reputation, and convert more readily than those who are not. Strategic considerations drive conversion among bluffing members, while identification with the administration determines conversion among other members. Compromise generates few conversions. A conservative estimate of bluffing suggests that the conversion of bluffers decided more than half the administration's critical votes. I speculate about a model to account for the observed bluffing.

Abstract (sommario):

Torrefaction is a thermal conversion method extensively used for improving the properties of biomass. Usually this process is conducted within a temperature range of 200-300 °C under an inert atmosphere with residence time up to 60 minutes. This work aimed to study the kinetic of thermal degradation of oil palm frond pellet (OPFP) as solid biofuel for bioenergy production. The kinetics of OPFP during torrefaction was studied using frequently used iso-conversional model fitting (Coats-Redfern (CR)) and integral model-free (Kissinger-Akahira-Sunose (KAS)) methods in order to provide effective apparent activation energy as a function of conversion. The thermal degradation experiments were conducted at four heating rates of 5, 10, 15, and 20 °C/min in a thermogravimetric analyzer (TGA) under non-oxidative atmosphere. The results revealed that thermal decomposition kinetics of OPFP during torrefaction is significantly influenced by the severity of torrefaction temperature. Via Coats-Redfern method, torrefaction degradation reaction mechanism follows that of reaction order with n = 1. The activation energy values were 239.03 kJ/mol and 109.28 kJ/mol based on KAS and CR models, respectively. Copyright © 2020 BCREC Group. All rights reserved

Abstract (sommario):

This paper presents a prototypical, Web based data conversion framework and its underlying data representation principles which allow conversions from and to any data format. Therefore, a data model is proposed which allows storing values of arbitrary types, including inter-data dependencies and meta information. Furthermore, an Extensible Markup Language (XML) based model to describe data formats is provided which allows specifying programs to convert data represented in existing formats both from and to the proposed data model. It will be shown that these programs are Turing complete, thus allowing the same arbitrarily complex conversions which are possible with Extensible Stylesheet Language Transformations (XSLT) or the C programming language. Finally, the components of a prototypical Web based implementation in form of a validator, a data converter and a data generator are described. In combination with a data editor, parts of this prototypical implementation are already employed in several use cases in the industry and other research projects to transform data between different formats.

Abstract (sommario):

AbstractThe Venerable Bede's Ecclesiastical History of the English People contains numerous accounts of what has been termed by some scholars "conversion by marriage," episodes in which a royal bride acts as the first agent of Christianity in a heathen land. Yct, a close examination of the accounts of the Northumbrian, Kentish, Middle Angle and South Saxon conversions reveals a manipulation of the historical accounts which serves to de-emphasize the power and participation of these queens in the subsequent Christianization of the nation. This article argues that the "conversion by marriage" model in the Ecclesiastical History is, in fact, not a viable model at all. This article will further argue that analysis of these particular conversion narratives reveals less about the power and influence of royal women (or Bede's own attitudes and concerns regarding the matter) and more about the larger agenda of the text. An analysis of the intersection of gender and faith within Bede's work points to the subtlety of purpose and design behind the massive undertaking which was the Ecclesiastical History.

Abstract (sommario):

ObjectiveTo assess frequency, duration and costs of Medicaid conversions that occur when severe injury causes patients to enrol in Medicaid to pay their hospital bills. Once enrolled, Medicaid pays all their medical bills, not simply their injury bill.Data sources2000–2005 West Virginia Medicaid claims data and 2000–2006 eligibility data for new enrollees under the age of 65. To model national costs, published Medicaid conversion rates across 14 states for 2003 and 2008 Healthcare Cost and Utilization Program Nationwide Inpatient Sample data.MethodsWe identified enrollees who had hospital inpatient claims for injury within 30 days of enrolment, then tabulated eligibility duration and payments by year and in aggregate. For those with open-ended eligibility, we assumed future annual claims payments would equal average payments in eligibility years 5–6. We multiplied the mean payments data adjusted to national prices with the estimated conversions nationally.ResultsOverall, 5.4% of hospitalised patients with injury in West Virginia converted to Medicaid, with 17% of conversions on Medicaid 7 years post injury. In 2010 dollars, Medicaid payments averaged $93 900 per conversion for non-injury medical care before the age of 65. Conversions added an estimated $87 in payments for non-injury care to governments’ medical payments per medically treated injury in the USA. They added 14% to governments’ gunshot and assault medical payments, 7.5% to its road crash medical payments and 6% to its total injury medical payments.ConclusionsThese findings increase the rationale for governments to partner in injury prevention efforts.

Abstract (sommario):

Abstract Summertime atmospheric circulation over the midlatitude western North Pacific (WNP) is influenced by anomalous convective activity near the Philippines. This meridional teleconnection, observed in monthly anomalies and known as the Pacific–Japan (PJ) pattern, is characterized by zonally elongated cyclonic and anticyclonic anomalies around the enhanced convection center and to its northeast, respectively, in the lower troposphere, with an apparent poleward phase tilt with height. The authors’ idealized two-layer linear model, whose basic state consists of a zonal subtropical jet and a pair of a monsoon system and a subtropical anticyclone, can simulate a PJ-like response against diabatic heating located between the pair. Each of the observed and simulated patterns can gain energy through barotropic and baroclinic conversions from the zonally varying baroclinic mean flow, in an efficiency comparable with that of energy generation due to the anomalous diabatic heating, indicating a characteristic of the pattern as a dry dynamical mode. In fact, the conversion efficiency is sensitive to the location of the anomaly pattern relative to the climatological-mean flow. Furthermore, the second-least damped mode identified in the idealized model bears certain resemblance with the observed PJ pattern, indicating its modal characteristics as well as a critical importance of these features in the mean field for the pattern. In addition to the PJ pattern, another meridional teleconnection pattern with high efficiency for its energy conversion is identified observationally in association with anomalous convection near the Bonin Islands. The anomalous circulation of the PJ pattern, in turn, can intensify the anomalous convective activity near the Philippines through enhancing evaporation and moisture convergence and dynamically inducing anomalous ascent. It is thus hypothesized that the PJ pattern can be regarded as a moist dynamical mode that sustains itself both via dry energy conversion and interaction with moist processes.

Abstract (sommario):

Abstract The conversion of barotropic to baroclinic M2 tidal energy is examined for a section of the Mid-Atlantic Ridge in the Brazil Basin using a primitive equation model. Model runs are made with different horizontal smoothing (1.5, 6, and 15 km) applied to a 192 km × 183 km section of multibeam bathymetry to characterize the influence of topographic resolution on the model conversion rates. In all model simulations, barotropic to baroclinic conversion is highest over near- and supercritical slopes on the flanks of abyssal hills and discordant zones. From these generation sites, internal tides propagate upward and downward as tidal beams. The most energetic internal tide mode generated is mode 2, consistent with the dominant length scales of the topographic slope spectrum (50 km). The topographic smoothing significantly affects the model conversion amplitudes, with the domain-averaged conversion rate from the 1.5-km run (15.1 mW m−2) 4% and 19% higher than for the 6-km (14.5 mW m−2) and 15-km runs (12.2 mW m−2), respectively. Analytical models for internal tide generation by subcritical topography predict conversion rates with modal dependence and spatial patterns qualitatively similar to the Princeton Ocean Model (POM) and also show a decrease in conversion with smoother topography. The POM conversion rates are approximately 20% higher than the analytical estimates for all model grids, which is attributed to spatial variations in the barotropic flow and near-bottom stratification over generation sites, which are incorporated in the model but not in the analytical estimates.

Abstract (sommario):

Abstract Using the T-matrix, or extended boundary condition, method, we model seismic-wave scattering from earth models with one-dimensional (1D) isolated topographic features. The earth model is simple, but we are primarily interested in free surface interactions. Scattering phenomena encountered in this model would presumably also operate in more realistic two-dimensional (2D) models. This study is motivated by observations suggesting that surface topography generates coda waves, which are relatively large-amplitude arrivals following major seismic phases. For sinusoidal periodic surfaces, large-amplitude anomalies in the surface displacement spectrum correspond to P-to-Rayleigh (P-Rg), S-to-Rayleigh (S-Rg), and other mode conversions. For isolated topographic features, these conversions still exist. We modeled teleseismic P-Rg conversions from isolated hills in order to understand and confirm the origin of observed conversions near the NORESS array. Parameter studies indicate that P-Rg and critical P-P conversion amplitudes increase roughly-linearly with scatterer relief, but are insensitive to changes in teleseismic ray parameter. Forward-scattered Rg waves are always two to three times larger than backscattered Rg waves. Poor fits to the observed P-Rg amplitudes (relative to the incident P waves) suggest that more realistic and complicated structure effects must be included. For example, it is well known that P-wave amplitudes vary considerably across the NORSAR array due to subsurface structures.

Abstract (sommario):

Abstract We have studied conversion of marrow cells to skeletal muscle in cardiotoxin-injured anterior tibialis muscle in a green fluorescent protein (GFP) to C57BL/6 transplantation model and ascertained that total body irradiation (TBI) with establishment of chimerism is a critical factor. Local irradiation has little effect in lower doses and was detrimental at higher doses. Whole body (1000 cGy) with shielding of the leg or a combination of 500 cGy TBI and 500 cGy local radiations was found to give the best results. In non-obese diabetic-severe combined immunodeficient (NOD-SCID) recipients, we were able to show that conversion could occur without radiation, albeit at relatively lower levels. Within 3 days of cardiotoxin injury, GFP-positive mononuclear cells were seen in the muscle, and within 2 weeks GFP-positive muscle fibers were identified. Conversion rates were increased by increasing donor-cell dose. Timing of the cardiotoxin injury relative to the transplantation was critical. These studies show that variables in transplantation and injury are critical features of marrow-to-muscle conversions. Irradiation primarily effects conversion by promoting chimerism. These data may explain the differences in the literature for the frequency of marrow-to-skeletal muscle conversion and can set a platform for future models and perhaps clinical protocols.

Abstract (sommario):

Abstract This paper begins with a simple problem: given the implicit Ignatian model for conversion and of conversion narratives for those already within the Christian fold, how did Jesuit missionaries in the colonies represent native conversion? To what extent were these colonial conversion narratives responding to the demands of Jesuit representational norms and to what extent did they reflect local realities? To address this question, this paper will examine stories of conversions of natives in public letters sent from Bahía and Goa and their immediate environs during the first thirty years of the missions in Brazil and India—annual letters but also other letters which were published in popular collections such as the Nuovi Avisi delle Indie di Portogallo series printed in Venice. The public cartas particulares, as opposed to the private hijuelas, were meant to be carefully crafted, and were explicitly intended to give a good account of the mission to the public in Europe. Since the public letters considered here were guided by Ignatius’ epistolary conventions and often placed into wide circulation, they provide an index of the rhetorical strategies and conversion narratives deemed successful by the Jesuit order in Europe in a period when Ignatius’ influence was still strongly felt.

Abstract (sommario):

This study aims to improve the interoperability between the application domains of Building Information Modelling (BIM) and Geographic Information Systems (GIS) by linking and harmonizing core information concepts. Many studies have investigated the integration of application schemas and data instances according to the BIM model IFC and the GIS model CityGML. This study investigates integration between core abstract concepts from IFC and ISO/TC 211 standards for GIS—independent of specific application schemas. A pattern was developed for conversion from IFC EXPRESS schemas to Unified Modelling Language (UML) models according to ISO/TC 211 standards. Core concepts from the two application domains were linked in the UML model, and conversions to implementation schemas for the Geography Markup Language (GML) and EXPRESS were tested. The results showed that the IFC model could be described as an ISO/TC 211 compliant UML model and that abstract concepts from ISO/TC 211 standards could be linked to core IFC concepts. Implementation schemas for BIM and GIS formats could be derived from the UML model, enabling implementation in applications from both domains without conversion of concepts. Future work should include refined linking and harmonization of core abstract concepts from the two application domains.

Abstract (sommario):

Abstract In An Inquiry into the Modes of Existence, which addresses itself to the profound challenge of how to “compose” a common world in the Anthropocene, Bruno Latour proposes that the mode of religion [REL] offers a model for all the others—that of reprise. Emerging from the practice of biblical exegesis, reprise refers to an open-ended process of meaning making opposed to the rigid certainties of fundamentalism. [REL] also contributes a concept of radical transformation through love (“conversion”). For Latour, two events from the Virgin Mary’s life—the Annunciation and the Assumption—illustrate reprise and conversion, both of which are necessary in coming to terms with monogeism, the knowledge that there is only one world. This essay examines Latour’s proposed relationship between reprise and conversion through a consideration of late medieval Marian devotion. Focusing on vernacular accounts of Mary’s Assumption, it argues that reprise leads to violent as well as loving conversions; indeed, violence can proceed in the name of love. The essay concludes that composition, reprise, and conversion come together in ways that trouble late medieval accounts of the Assumption, the mode of religion, and life in the Anthropocene.

Abstract (sommario):

The process of CO2 reformation of CH4 was conducted over a 5% Ni/SBA-15 catalyst under various experimental conditions. Operating temperature (600-750 �C), gas hourly space velocity (4000-12000 hr-1), and CO2/CH4 feed molar ratio (0.67-1.50) were selected as independent parameters (factors). Process performances were evaluated as conversions of CH4 (21.1-79.6%) and CO2 (42.4-98.7%) as well as H2/CO product molar ratio (0.573-0.992). All process performances were enhanced at higher levels of temperature and low values of gas velocity. An increase in feed molar ratio has determined a significant increase in CH4 conversion and a slighter decrease in CO2 conversion and H2/CO molar ratio. A statistical model based on a 23 factorial plan was used to predict the process performances depending on its factors.

Abstract (sommario):

Abstract The evolution and spatial distribution of the energetics of African waves are studied. Complete eddy energy equations for an open system are derived for the computation of energy transformations during wave generation and dissipation. It is found that baroclinic overturning is the dominant energy source, although barotropic conversions can be almost equally important when there is concentrated moist convection south of the jet or shallow cumulus convection beneath the jet. The generation of active waves usually results from the nearly in-phase evolution of baroclinic and barotropic conversions, which are associated with significant rainfall over Africa. Significant barotropic instability associated with the horizontal shear is usually induced by concentrated deep convection on the southern flank of the jet. Barotropic conversions associated with the vertical wind shear may attain even greater magnitudes than that associated with the horizontal shear when shallow cumulus convection beneath the jet is strong. The eddy available potential energy consumed by the baroclinic overturning is compensated directly by the conversion of zonal to eddy available potential energy and the generation of eddy potential energy by diabatic heating. These direct conversions of latent heat and zonal available potential energy suggest that interactions across space scales, from convective space scales to the large scales, are important for generating African waves. The convectively induced barotropic instability may enhance baroclinic overturning through the resonance between these two instabilities. This leads to the nonlinear interaction of the waves with convection, corresponding to the formation of organized precipitation migrating with the waves. A space–time spectral analysis shows that the dispersion characteristics of African easterly waves with wavelengths between 2650 and 4000 km do not follow the dispersion relation of the shallow water waves, indicating that these waves, similar to other easterly waves in the Tropics, possess significant nonlinearity, and cannot be fully explained by linear wave theory.

Abstract (sommario):

The current study deals with the maximization of NaOH conversion using step-wise regression analysis in a CSTR. The dependence of temperature, volume, agitation rate, and feed rate on reactor performance is examined as well as interaction outcome of the operating parameters. The concentration of the reactants was fixed at 0.1 M. The steady state conversion with respect to NaOH is analyzed to find the process performance. Step-wise regression analysis is used to remove an insignificant factors. The agitation rate (X2) and feed rate (X3) proved to have an insignificant influence on the reaction conversion at a significant level (α) of 5%. Consequently, the temperature (X1) and reaction volume (X4) were found to have significant effect on the reaction conversion using step-wise regression. The temperature and volume dependence on steady state NaOH conversion were described by a polynomial model of 2nd and 3rd order. A maximal steady state conversion equal to 63.15% was obtained. No improvement was found in reaction conversion with 3rd order polynomial, so the second order polynomial is considered as the optimum reaction conversion modal. It may be recommended that 2nd order regression polynomial model adequately represents the experimental data very well.

Abstract (sommario):

Land-use change and its effects on hydrological processes in a watershed strongly determine the adopted land and water resource management. Human activities that lead to the conversion of forest to non-forest land can continue to modify hydrological systems. This study was intended to analyze the variation in baseflow recession curves as a function of land-use change in the Keduang Watershed, Wonogiri Regency, Jawa Tengah Province. The results showed that the types of land-use conversions had the same model of recession: Qmodel= 0.9747*Exp(-0.2357*ts) for preserved forests, Qmodel= 0.1266*Exp(-0.1238*ts), to represent the conversion of forests to agricultural areas, Qmodel= 0.1108*Exp(-0.1008*ts) for forests to settlements, Qmodel= 0.7628*Exp(-0.2015*ts) for unchanged agricultural areas, Qmodel= 0.0465*Exp(-0.1141*ts) for the conversion of agricultural areas back to forests, Qmodel= 0.1072*Exp(-0.0952*ts) for agricultural areas to settlements, and Qmodel= 0.3359*Exp(-0.1542*ts) for settlements. Overall, the equations indicate that forests can store water better and longer than converted to agricultural fields and settlements.

Abstract (sommario):

Conversion between space rectangular (X, Y, Z) and curvilinear (φ, λ, h) coordinates is an important task in the field of Surveying, geodesy, positioning, navigation, mapping etc. Different techniques which include iterative methods, non-iterative techniques and closed form algebraic methods have been applied over the years to carry out the coordinate conversion. However, the results obtained using these techniques are deficient in one way or the other due to the inherent limitations such as inability to produce results for curvilinear coordinates when the values of X, Y and Z are subsequently or simultaneously equal to zero. Therefore, this study attempts to put forth an optimum coordinate conversion technique between space rectangular and curvilinear coordinates. The data used are coordinates of points which include the space rectangular coordinates and their equivalent curvilinear coordinates. They were observed and processed in Nigeria using Doppler 9 software by African Doppler Survey (ADOS) and they were confirmed to be of first order accuracy and hence of high quality. The data processing involved the design of the optimum techniques equations, coding of the algorithms and necessary computations to obtain results. Analyzing the results obtained, it can be inferred that the designed optimum model has successfully carried out the conversion between space rectangular and curvilinear coordinates. Therefore, the optimum technique model is recommended for use for the conversions from Space rectangular coordinates to Geocentric, Geodetic, Reduced coordinates and vice versa.

Since the composition of crude bio-oil was complex, model compounds were usually used in the study of cracking to simulate the actual bio-oil. However, the cracking of pure model compound mixture generated an inferior oil phase which had a high content of oxygenated byproducts. When ethanol was adopted as the co-reactant, the reactant conversion, yield and quality of oil phase were obviously improved. The conversions of the reactants were 100% and the selectivity of the oil phase was 31.5wt% when the concentration of model compound mixture in the feed reached 30%. Meanwhile, the oil phase also had a superior quality which was entirely composed of aliphatic and aromatic hydrocarbons.

Abstract (sommario):

We explore the kinetics of a three-state strain pseudospin model for a square/rectangle ferroelastic transition, described by a temperature dependent hamiltonian without quenched disorder, using temperature quench Monte Carlo simulations. The model hamiltonian includes power law anisotropic long range interactions, which lock the domain walls in a symmetry breaking diagonal direction. In athermal parameter regime, there are fast conversions at the athermal transition temperature, but with delay tails above it, as in experiment. The conversion delay tails have a Vogel-Fulcher divergence at transition to austenite. The incubation delays and their insensitivity to elastic energy scales are attributed to entropy barriers. Temperature cycling shows hysteretic behavior in physical quantities.

Abstract (sommario):

This article takes a sociocultural anthropological approach to conversion. It asks not about the causes of conversion, but about the kinds of cultural changes conversion produces and the mechanisms by which it brings about such changes. Drawing on the author’s research among a recently converted group in Papua New Guinea and on other work produced by scholars working in the anthropology of Christianity, the article argues that Christianity is a culture of secondarity, designed to come after another culture that previously guided its converts. Moreover, Christian converts tend to engage their prior cultures not by completely rejecting them, but by evaluating their components critically in relation to new Christian values. This produces a duplex cultural formation that regularly fosters critical reflection and ongoing cultural change. This model of change is briefly distinguished from more common models of syncretism, suggesting a new understanding of the relationship between conversion and cultural change.本文从社会文化人类学的角度探讨转化这课题。所问的问题不是转化的原因，而是由转化而产生的文化转变，及带来这种转变的机制。从作者对巴布亚新几内亚最近信主的群体的研究，及其他基督教人类学学者的著作，本文论证基督教乃是第二类文化，是在之前引导人信主的文化之后才进入的文化。而且，信主的人倾向与前文化继续接触，不是完全地拒绝，而是以基督教新的价值观来衡量原文化的各个因素。这就形成了双层文化，促进尖锐的反思和不断的文化转变。这种转变模式不同于常见的融合主义的模式，而是带出一种对转化与文化改变之间的关系的新的认识。El artículo adopta un enfoque sociocultural antropológico sobre la conversión. No trata las causas de la conversión, sino los tipos de cambios culturales producidos por la conversión y los mecanismos por los cuales se producen tales cambios. Se toma como punto de partida la investigación hecha entre un grupo de recién convertidos en Papúa Nueva Guinea y en otro trabajo realizado por profesionales en el área de antropología del cristianismo; el artículo sostiene que el cristianismo es una cultura de secundariedad que aparece luego de que otra cultura haya antes guiado a los ahora convertidos.Además, los cristianos convertidos se relacionan con sus culturas anteriores evaluando críticamente sus componentes en relación a los nuevos valores cristianos pero no las rechazan completamente. Esto produce una doble formación cultural que fomenta, en forma regular, la reflexión crítica y los cambios constantes. Este modelo de cambio se lo distingue brevemente de los modelos más comunes de sincretismo, y sugiere una nueva comprensión de la relación entre la conversión y el cambio cultural.This article is in English.
