Annotation:

Background Loa loa and Mansonella perstans–the causative agents of loiasis and mansonellosis—are vector-borne filarial parasites co-endemic in sub-Saharan Africa. Diagnosis of both infections is usually established by microscopic analysis of blood samples. It was recently established that the odds for detecting Plasmodium spp. is higher in capillary (CAP) blood than in venous (VEN) blood. In analogy to this finding this analysis evaluates potential differences in microfilaraemia of L. loa and M. perstans in samples of CAP and VEN blood. Methods Recruitment took place between 2015 and 2019 at the CERMEL in Lambaréné, Gabon and its surrounding villages. Persons of all ages presenting to diagnostic services of the research center around noon were invited to participate in the study. A thick smear of each 10 microliters of CAP and VEN blood was prepared and analysed by a minimum of two independent microscopists. Differences of log2-transformed CAP and VEN microfilaraemia were computed and expressed as percentages. Furthermore, odds ratios for paired data were computed to quantify the odds to detect microfilariae in CAP blood versus in VEN blood. Results A total of 713 participants were recruited among whom 52% were below 30 years of age, 27% between 30–59 years of age and 21% above 60 years of age. Male-female ratio was 0.84. Among 152 participants with microscopically-confirmed L. loa infection median (IQR) microfilaraemia was 3,650 (275–11,100) per milliliter blood in CAP blood and 2,775 (200–8,875) in VEN blood (p<0.0001), while among 102 participants with M. perstans this was 100 (0–200) and 100 (0–200), respectively (p = 0.44). Differences in linear models amount up to an average of +34.5% (95% CI: +11.0 to +63.0) higher L. loa microfilaria quantity in CAP blood versus VEN blood and for M. perstans it was on average higher by +24.8% (95% CI: +0.0 to +60.5). Concordantly, the odds for detection of microfilaraemia in CAP samples versus VEN samples was 1.24 (95% CI: 0.65–2.34) and 1.65 (95% CI: 1.0–2.68) for infections with L. loa and M. perstans, respectively. Conclusion This analysis indicates that average levels of microfilaraemia of L. loa are higher in CAP blood samples than in VEN blood samples. This might have implications for treatment algorithms of onchocerciasis and loiasis, in which exact quantification of L. loa microfilaraemia is of importance. Furthermore, the odds for detection of M. perstans microfilariae was higher in CAP than in VEN blood which may pre-dispose CAP blood for detection of M. perstans infection in large epidemiological studies when sampling of large blood quantities is not feasible. No solid evidence for a higher odds of L. loa microfilariae detection in CAP blood was revealed, which might be explained by generally high levels of L. loa microfilaraemia in CAP and VEN blood above the limit of detection of 100 microfilariae/ml. Yet, it cannot be excluded that the study was underpowered to detect a moderate difference.

An 80-kDa protein, prominently expressed in smooth muscle, was microsequenced and identified as LPP, the product of the lipoma-preferred partner gene (Petit MMR, Mols R, Schoenmakers EFPM, Mandahl N, and Van de Ven WJM. Genomics 36: 118–129, 1996). Using a specific anti-LPP antibody, we showed, in Western blots and with immunofluorescence microscopy, the selective expression of LPP in vascular and visceral smooth muscles (∼0.5–1 ng/μg total protein). In other mature (noncultured) tissues, including heart and skeletal muscle, the protein is present only in trace amounts and is closely correlated with the levels of the smooth muscle marker α-actin. In freshly isolated guinea pig bladder smooth muscle cells, immunofluorescence images showed LPP as linear arrays of punctate, longitudinally oriented staining superimposed with vinculin staining on the plasma membrane surface. A corresponding pattern of periodic labeling at the membrane in transverse sections of bladder smooth muscle suggested an association of LPP with peripheral dense bodies. In cultured rat aortic smooth muscle cells, LPP colocalized with vinculin at focal adhesions but not with p120 catenin or α-actinin. Overexpression of the protein increased EGF-stimulated migration of vascular smooth muscle cells in Transwell assays, suggesting the participation of LPP in cell motility. The Rho-kinase inhibitor Y-27632 dissociated focal adhesions and LPP staining at the cell periphery and enhanced the nuclear accumulation of LPP induced by leptomycin B, indicating that LPP has a potential for relocating to the nucleus through a shuttling mechanism that is sensitive to inhibition of Rho-kinase.

In this paper, we will consider the Laplace decomposition method (LDM) for finding series solutions of nonlinear oscillator differential equations. The equations are Laplace transformed and the nonlinear terms are represented by He’s polynomials. The solutions are compared with the numerical (fourth-order Runge-Kutta) solution and the solution obtained by the Adomian decomposition method. The suggested algorithm is more efficient and easier to handle as compared to the numerical method. The results illustrate that LDM is an appropriate method in solving the highly nonlinear equations.

Zařízení založená na spinových vlnách mají potenciál být využita ve výpočetní technice s nízkou spotřebou energie. Pro úspěšné využití je samozřejmě potřeba spojit více takových zařízení na jednom čipu, součástí čehož musí být zatáčení spinových vln zahnutými vlnovody. Problém zatáčení spinových vln v dipolárně výměnném režimu zatím nebyl uspokojivě vyřešen, vyzkoušené přístupy vedly ke ztrátě intenzity a fázové koherence. V této diplomové práci jsme zkoumali dva systémy, které by mohly být využity k zatáčení spinových vln. Prvním z nich jsou tenké metastabilní vrstvy slitiny železa a niklu. Paramagnetická metastabilní fcc vrstva, která byla epitaxně narostena na substrátu z mědi, může být transformována do stabilní ferromagnetické bcc fáze pomocí fokusovaného iontového svazku. Tato technika nám dává prostorovou kontrolu nad transformačním procesem a strategie skenování svazkem nám dokonce umožňuje určit směr mangetické anisotropie. Magnetické vlastnosti struktur vytvořených touto metodou a lom spinových vln mezi doménami s odlišným směrem magnetické anisotropie byly změřeny pomocí mikroskopie Brillouinova rozptylu světla. Druhým zkoumaným systémem jsou zvlněné vlnovody, jejichž zvlnění indukuje magnetickou anisotropii. Zvlnění magnetické vrstvy je vytvořeno depozicí nemagnetických vlnek na substrátu indukovanou fokusovaným elektronovým svazkem a následnou depozicí magnetického materiálu. Byly vyrobeny různé návrhy zatočených zvlněných vlnovodů a změřili jsme šíření spinových vln jejich zatáčkami pomocí mikroskopie Brillouinova rozptylu světla. Využili jsme také mikromagnetické simulace pro získání hlubšího porozumění zkoumané problematiky a pro hledání vhodných návrhů experimentů.

Informe de Seminario para optar al grado de Licenciado en Filosofía
La presente tesina realiza en su marco teórico una breve introducción a las ideas del Círculo de Viena sobre el significado, para a continuación presentar el ataque frontal a las bases del positivismo lógico llevado a cabo por Quine, cuyo original sistema filosófico involucra sostener tesis filosóficas de carácter abarcador, dejándolas en un sector indefinido entre lo semántico, lo epistemológico y lo metafísico. Por lo anterior, la estructura de la exposición del sistema quineano se hará desde “fuera” hacia “adentro”, es decir, yendo del ataque hacia Carnap y el Círculo, pasando por sus tesis del compromiso ontológico, el holismo semántico, la indeterminación de la traducción, la relatividad ontológica y la indeterminación de la referencia, para luego ir hacia las presuposiciones empíricas tácitas que hacen su sistema creíble, o sea, la reificación como punto de continuidad entre el lenguaje natural y la teoría científica, junto con su concepción de un significado estimulativo compatible con el conjunto de sus proposiciones filosóficas. Una vez en el interior del sistema se atacará la noción de “reificación quineana” que involucra que el mundo es concebido desde nuestra niñez como un conjunto no ordenado de experiencia siendo ordenado recién con la adquisición de un lenguaje cualquiera, cosa incompatible con lo que la investigación en psicología del desarrollo ha descubierto. Finalmente, considerando que lo que muestran los experimentos hechos en niños prelingüísticos es una prueba suficiente de la falta de plausibilidad del edificio quineano, entonces se intentará hacer una reconstrucción sobre las soluciones que se han formulado históricamente a los problemas del “significado”, la “referencia” y la “comunicación”, lo que implicará inmediatamente una propuesta sobre las nociones conceptuales que debe contener una teoría más completa cuyo objeto sean los lenguajes naturales.

Entre cahors et soturac, le vignoble d'appellation d'origine controlee cahors se situe dans la moyenne vallee du lot, a terrasses etagees siliceuses, et sur ses versants et plateaux bordiers partages entre les calcaires des eres secondaires et tertiaires. Pour etudier et cartographier les terroirs des 45 communes qui englobent l'aire (a la demande des instances viticoles locales et nationales), nous avons defini une grille de douze criteres de differenciation des terroirs qui nous a permis de les decrire et de les cartographier au 1/25 000. Cette approche epistemologique et appliquee nous a amene a prolonger notre recherche suivant trois axes : - une etude affinee des terroirs par fosses et sondages, qui a conduit a un approfondissement a l'aide d'analyses pedologiques et montre la differenciation des terroirs par leur sol, - une etude des topoclimats de l'aire, par l'examen des temperatures quotidiennes en fonction des terroirs, par l'elaboration d'un modele numerique de terrain (mnt) permettant l'examen des ombres portees en fonction de la pente et de l'exposition, - une etude des rapports entre terroirs et qualites des vins sur cinq annees, par degustations et analyses chimiques de microvinifications, qui montre une hierarchie entre les terroirs. Ces prolongements ont confirme notre cartographie, l'individualite de chaque terroir, ce que nous avons appele le fait terroir. Enfin, un des aboutissements de nos recherches a consiste en l'etude, a l'echelle de la parcelle, des possibilites de reconnaissance d'une appellation +premier cru cahors ;, qui peut donner un nouvel elan a l'appellation cahors. Ce volet de recherche a permis de construire une base de donnees qui peut etre a l'origine d'un systeme d'information geographique.

Between cahors and soturac, the vineyard of cahors - a guaranteed vintage- is situated in the mid-lot valley, which has silicious terraced rows on its hillsides, and on its bordering plateaux, composed of limestone of the secondary or tertiary geological eras. In order to study and do a cartography of the + terroirs ; in the 45 rural districts which include the area concerned (a project commissioned by the local and national authorithies), we defined a scale comprising twelves criteries for differenciating the +terroirs ;; this enabled us to describe and do a cartography of them on a scale of 1/25 000. This epistemological and applied approach led us to extend our research by following three main lines: - an extensive study of the +terroirs ; by taking soil samples, which was consequently furthered by soil analyses and they showed the differenciation between the various +terroirs; according to their soil; - a study of the area's topoclimates, by examining the daily temperatures according to each + terroir ;, and by elaborating a numerical model of ground which enabled us to examine the shadows cast according to the slopes or the exposure; - a study of the links between each + terroirs ; and the qualities of the wine over five years, either by tasting them or making chemical analyses of the microvinifications, which showed that there is a hierarchy between the + terroirs ;. Those extensions of our study confirmed both the cartography we had made, and the individual character of each + terroir ;, which we called the + fait terroir ;. Finally, one of the outcomes of our research consisted in studying the possibility to award an appellation + first-class cahors vintage ; on the scale of the patch, which would boost the cahors appellation. This section of our research enabled us to compile a database which could lead to the creation of a geographical information system

Deep amplitude minima are observed in the daily records of Very Low Frequency (VLF, between 3 - 30 kHz) wave amplitudes. Amplitude minima are attributed to modal interference and modal conversion of waves propagating in the Earth - Ionosphere waveguide. The time of amplitude minima is related with the localization of the Terminator line and, therefore, is denominated of Terminator Time or TT time. In this work, we developed a methodology based on the monitoring of TT time to infer the distance of modal interference D and its temporal variation in relation to atmospheric and natural phenomena. For this purpose, we used data provided by the South America VLF Network (SAVNET) to the period 2007 - 2011. The results showed that the methodology is a promising tool to study the dynamics of the lower ionosphere, by means of the daily values of the undisturbed nighttime ionospheric height(hN). We identified short-term and long-term time variations of hN, where the long-term variation is possibly related with the solar activity cycle. We propose the use of this method to search for seismic- electromagnetic effects, and that it should be applied to medium and short propagation paths. Using the Long Wave Propagation Capability (LWPC) code, we simulated TT times and the results show good agreement with the observations, so a value for nighttime height hN = 88 km is suggested. This work will contribute to a greater viability of the use of the VLF technique for the study of the lower ionosphere and the forcings acting on this region of the atmosphere.
Pronunciados mínimos de amplitude são observados nos registros diários de sinais de muito baixa frequência ou VLF (do inglês Very Low Frequency, entre 3 - 30 kHz). A presença destes mínimos é atribuída a interferência e conversão modal de ondas se propagando no guia de onda Terra - Ionosfera. Os tempos de ocorrência destes mínimos são relacionados com a localização do Terminadouro e, por isso, são denominados de tempos de Terminadouro ou Tempos TT. Neste trabalho, desenvolvemos uma metodologia baseada no monitoramento dos tempos TT para inferir a distância de interferência modal D, e sua variabilidade temporal em relação a fenômenos atmosféricos e naturais. Para isso, utilizamos dados fornecidos pela rede SAVNET (South America VLF Network) durante o período 2007 - 2011. Os resultados mostraram que a metodologia é relevante para estudar a dinâmica da baixa ionosfera, através da obtenção de valores diários da altura noturna hN. Identificamos variabilidades de curto e longo período para hN, sendo estas últimas relacionadas ao ciclo de atividade solar. O método deverá ser aplicado à procura de efeitos sismo-eletromagnéticos utilizando caminhos com comprimento médios ou curtos. Foram realizadas simulações dos tempos TT, utilizando o código Long Wave Propagation Capability (LWPC), que mostraram boa concordância com as observações, sugerindo um valor de hN = 88 km para a altura noturna da baixa ionosfera. Os resultados apresentados neste trabalho contribuem para uma maior viabilização do uso da técnica de VLF, para o estudo da baixa ionosfera e os forçantes que agem sobre esta região da atmosfera terrestre.

Annotation:

The objective of this thesis is to use radio emissions from lightning, known as `radio atmospherics' or `sferics', to study the temporal and spatial variation of the lower ionosphere, a layer of ionized atmosphere beginning at $\sim$70 km altitude (D-region). Very Low Frequency (VLF, 3$-$30kHz) radio waves are a useful diagnostic for lower ionospheric monitoring due to their reflection from this region and global propagation. Traditionally, the lower ionosphere has been sensed using single-frequency VLF transmitters allowing for analysis of a single propagation path, as there are only a small number of transmitters. A lightning stroke, however, releases an intense amount of impulsive broadband VLF radio energy in the form of a sferic, which propagates through the Earth-ionosphere waveguide. Lightning is globally distributed and very frequent, so a sferic is therefore also a useful diagnostic of the D-region. This is true both for ambient or quiet conditions, and for ionospheric perturbations such as solar flare x-ray bursts. Lightning strokes effectively act as separate VLF transmitting sources. As such, they uniquely provide the ability to add a spatial component to ionospheric remote sensing, in addition to their broadband signature which cannot be achieved with man-made transmitters. We describe the methods of processing in detail. As an example, we analyze a solar flare during which time there is a significant change in magnitude and frequency content of sferics. This disturbance varies with distance from the source, as well as time. We describe the methods of processing in detail, and show results at Palmer Station, Antarctica for both a quiet and active solar day.

Annotation:

Over the last two and a half years, Covanta Energy, working with their technology partner, Martin GmbH of Germany, has developed and commercialized a new technology for reducing NOx emissions from Energy from Waste (EfW) facilities. NOx levels below 60 ppm (7% O2) have been reliably achieved, which is a reduction of 70% below the current EPA standard and typical levels of today’s EfW facilities in the United States. This technology represents a significant step forward in NOx control for the EfW industry. The technology, known as VLN™, employs a unique combustion system design, which in addition to the conventional primary and secondary air streams, also features a new internal stream of “VLN™-gas,” which is drawn from the combustor and re-injected into the furnace. The gas flow distribution between the primary and secondary air, as well as the VLN™-gas, is controlled to yield the optimal flue gas composition and furnace temperature profile to minimize NOx formation and optimize combustion. The VLN™ process is combined with conventional, aqueous ammonia SNCR technology to achieve the superior NOx performance. The SNCR control system is also integrated with the VLN™ combustion controls to maximize NOx reduction and minimize ammonia slip. A simplified version of the process, known as LN™, was also developed and demonstrated for retrofit applications. In the LN™ process, air is used instead of the internal VLN™ gas. The total air flow requirement is higher than in the VLN™ process, but unchanged compared to conventional systems, minimizing the impact on the existing boiler performance and making it ideal for retrofit applications. Covanta first demonstrated the new VLN™ and LN™ processes at their Bristol, Connecticut facility. One of Bristol’s 325 TPD units was retrofitted in April of 2006 to enable commercial scale testing of both the VLN™ and LN™ processes. Since installing and starting up the new system, Bristol has operated in both VLN™ and LN™ modes for extended periods, totaling more than one year of operation at NOx levels at or below 60 ppm (7% O2). The system is still in place today and being evaluated for permanent operation. Based on the success of the Bristol program, Covanta installed LN™ NOx control systems in a number of other existing units in 2007 and 2008 (total MSW capacity of over 5000 TPD), and is planning more installations in 2009. All of these retrofits utilize the Covanta LN™ system to minimize any impacts on existing boiler performance by maintaining existing excess air levels. Going forward, Covanta is making the LN™ technology available to its existing client base and is working with interested facilities to complete the necessary engineering and design modifications for retrofit of this innovative technology. For new grassroots facilities, Covanta is offering the VLN™ system with SNCR as its standard design for NOx control. An additional feature, particular to VLN™, is the reduced total combustion air requirement, which results in improved boiler efficiency. This translates into increased energy recovery per ton of waste processed. In addition to introducing the VLN™ and LN™ processes, this paper will provide an overview of the Bristol development and demonstration project. NOx and NH3 slip data from Bristol will be presented, illustrating the extended operating experience that has been established on the system. Other operating advantages of the new technology will also be discussed, along with lessons learned during the start-up and initial operating periods. The VLN™ technology has been demonsrated to decrease NOx emissions to levels well below any yet seen to date with SNCR alone and is comparable to SCR-catalytic systems. The result is a significant improvement in NOx control for much less upfront capital cost and lower overall operating and maintenance costs. VLN™ also also goes hand in hand with higher energy efficiency, whereas SCR systems lower energy efficiency due to an increased pressure drop and the need for flue gas reheat. The commercialization of the VLN™ and LN™ processes represents a significant step forward in the reduction of NOx emissions from EfW facilities.

Las acciones realizadas para propiciar la permanencia de los estudiantes en los programas de educación superior son muy variadas y van desde políticas definidas por el ministerio de educación nacional (men), hasta estrategias diseñadas por las instituciones de educación superior (ies). Lo que ocurre es que estas acciones en su mayoría se han orientado a facilitarle a los estudiantes, la mejor manera de superar la incidencia que tienen los factores económicos en la permanencia de sus estudios, y muy pocas se enfocan en aspectos considerados menores, pero que pueden llegar a contribuir en permanencia de los estudiantes, al valorar los talentos o hobbies con que cuentan los estudiantes. Por lo tanto, este documento de trabajo muestra la importancia que algunos factores sociales de la vida universitaria pueden llegar a tener en la permanencia de los estudiantes en sus programas académicos matriculados, lo cual no se aleja de lo que deben hacer las instituciones. Este trabajo es fruto de una investigación no experimental, descriptiva y transversal que permitió describir los factores que más incidencia tienen en la decisión de abandonar o permanecer en un programa matriculado de la escuela ecacen, además de recolectar información primaria de estudiantes catalogados como antiguos, y una revisión detallada otras investigaciones acerca del fenómeno de la deserción, sin embargo es necesario señalar que para el caso de este documento de trabajo se seleccionan solo las preguntas relacionadas con los talentos que poseen los estudiantes y las que indagan acerca de la motivación para permanecer en los programas. De esta manera, se encuentra que los talentos o hobbies que poseen los estudiantes pueden ser utilizados para propiciar un mejor ambiente universitario y contribuir a la permanencia en sus programas, además de verificar que el desarrollo de estos talentos, que también ayudan a la realización del ser humano, puede ser impulsado por las instituciones de educación superior.

Los beneficios asociados a los vehículos autónomos pueden tener un impacto transformacional en el sector, contribuyendo a un transporte más eficiente, inclusivo y sostenible. Sin embargo, dado el estado embrionario en el despliegue de la tecnología, estos potenciales beneficios aún no se encuentran del todo probados en la realidad. Asimismo, existe una serie de riesgos asociados al vehículo autónomo, que requieren del accionar de los reguladores para su mitigación. En este contexto, el sector público deberá jugar un rol clave en el diseño de un marco regulador que reduzca las barreras de entrada y fomente la innovación en el sector, al tiempo que garantice la implementación tecnológica con adecuados grados de seguridad, confiabilidad y funcionalidad. A su vez, este marco regulatorio debe ser lo suficientemente flexible para adaptarse a medida que evoluciona la tecnología. Los países de América Latina y el Caribe (ALC) se encuentran muy rezagados en los ámbitos de investigación, testeo y debate público de esta tecnología en comparación a países avanzados. Con el fin de contribuir a cerrar esta brecha, este documento identifica las prácticas más habituales y lecciones aprendidas en diez países líderes a nivel mundial, para guiar las iniciativas que se realicen en la región. El enfoque que se ha identificado mayoritariamente en esta muestra de geografías ha sido el de sandbox regulatorio, conforme al cual se van desarrollando pruebas mientras la tecnología madura, creando entornos seguros y que permitan la innovación. Así, en este documento se presenta una guía para implementar sandboxes regulatorios de despliegue de vehículos autónomos en ALC.
