In this work the synthesis of the heavy lanthanides and yttrium were carried out, using the direct addition of the sodium terephthalate in the respectives metallic chloride solutions. The synthesized compounds were characterized by simultaneous Thermogravimetry and differential scanning calorimetry analysis (TG-DSC), differential scanning calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analyses coupled to Fourier Transform Infrared spectroscopy (TG-FTIR), EDTA complexometry and X ray powder Diffractometry. From the data, it was possible to obtain the general formula of each compound (Ln2(TFta)3.nH2O, where Ln = Tb(III), Dy(III), Ho(III), Er(III), Tm(III), Yb(III), Lu(III) and Y(III), TFta = terephthalate, and n = 4,5 (Tb, Dy and Ho), 4,0 (Er, Tm and Y), 5,0 (Yb) and 6,5 (Lu)), as well as unreported information about the thermal properties, in air atmosphere, thermal stability; molar dehydration enthalpy; main evolved gases from thermal decomposition (H2O, CO2 and CO), the coordination mode between metal and ligand and performing the comparison of the results of X -ray diffraction of the compounds synthesized by the powder method using and the single crystal obtained by hydrothermal synthesis reported in the literature.

In the last years the interest in the chemistry of coordination compounds of polycarboxylic acids and lanthanides or transition metals has substantially increased, due to their interesting characteristics, such as gas storage (Metal-organic frameworks compounds), luminescence and magnetic properties. A literature survey reveals few studies investigating the properties of lighter lanthanide coordination compounds obtained by soft chemistry routes, and mainly the study of their thermal properties in air atmosphere. In this work the reaction between sodium isophthalate and lighter lanthanides solutions (La – Gd) except Pm, led to the formation of two new coordination compounds, and five already reported in the literature, whose thermal behavior and infrared spectra was investigated. The compounds was characterized by simultaneous Thermogravimetric and differential scanning calorimetry analysis (TG-DSC), differential scanning calorimetry (DSC), Fourier Transform Infrared Spectroscopy (FTIR), thermogravimetric analyses coupled to Fourier Transform Infrared spectroscopy (TG-FTIR) and EDTA complexometry. With the TG-DSC and TG-FTIR data was possible to determinate the general formula of compounds (Ln2(L)3.nH2O, where Ln = La – Gd, except Pm, L = isophthalate, n varies from 2 to 13,5), thermal stability and molar dehydration enthalpy per water molecule, as well as the main evolved gases during thermal decomposition (H2O, CO2 and CO). The FTIR spectra suggest that metal-ligand coordination occurs in the bridging bidentate mode.
Nos últimos anos, tem surgido um grande interesse na química dos compostos de coordenação de ácidos dicarboxílicos com metais de transição ou lantanídeos, devido a sua aplicabilidade em compostos de estrutura molecular porosa (Metal-organic frameworks) e interessantes propriedades luminescentes. Uma revisão na literatura revela a falta de trabalhos estudando de forma sistemática as propriedades térmicas de compostos de coordenação de lantanídeos leves com o ligante isoftalato em atmosfera de ar, principalmente obtidos por meio de vias sintéticas classificadas como brandas. Neste trabalho, foi realizada a síntese dois novos compostos de coordenação, e cinco já reportados pela literatura em diferentes trabalhos, utilizando a metodologia de reação direta entre soluções de ácido isoftálico (ácido 1,3- benzenodicarboxílico) e de lantanídeos (La – Gd) exceto Pm. Os compostos sintetizados foram caracterizados e estudados através das técnicas de análise termogravimétrica e calorimetria exploratória diferencial simultânea (TG-DSC), Calorimetria exploratória diferencial (DSC) e Espectroscopia de Infravermelho por Transformada de Fourrier (FTIR) e Complexometria por EDTA. A partir das curvas TG-DSC e TG-FTIR foi possível a determinar a estequiometria dos compostos, com fórmula geral Ln2(L)3.nH2O (Ln = La a Gd, exceto Pm, L = isoftalato) n variando de 2 a 13,5, bem como estabilidade térmica, grau de hidratação dos compostos e os principais produtos gasosos formados pela decomposição térmica (H2O, CO2 e CO). Através das análises de FTIR pode-se sugerir que o tipo de coordenação entre metal e o ligante é bidentado em ponte.

Neste trabalho foi estudado o papel das topoisomerases celulares (I, IIα e IIβ) na replicação, usando os adenovírus como modelo. Os adenovírus apresentam um genoma de ADN de cadeia dupla e são responsáveis por infecções respiratórias, gastro-intestinais, oftalmológicas, neurológicas e genito-urinárias. São organismos ubiquitários, infectam passáros e a maioria dos mamíferos, incluindo o Homem. Com efeito, a importância destes vírus tem vindo a aumentar por surgirem associados a novos quadros nosológicos (imunodeficiências, transplantes de órgãos) e por poderem vir a funcionar como vectores terapêuticos em doenças genéticas e na viroterapia do cancro. No presente trabalho (1) analisámos a distribuição das topoisomerases I, IIα e IIβ no núcleo de células infectadas, com utilização de tecnologias modernas de microscopia, (2) caracterizámos funcionalmente os locais de acumulação destas enzimas, (3) testámos se a replicação e a transcrição virais eram necessárias ao seu recrutamento, (4) estudámos a dinâmica das topoisomerases I e IIα in vivo por FRAP, (5) realizámos a analise mutacional da topoisomerase I e (6) quantificámos as concentrações e actividades catalíticas das topoisomerases antes e depois da infecção. Por fim, (7) abordámos a conexão funcional entre estas proteínas celulares e a replicação do vírus por depleção selectiva de cada topoisomerase (siRNA), evitando os efeitos genotóxicos dos fármacos antitopoisomerase. Os resultados obtidos permitem concluir que ambos os tipos de topoisomerases (I e II) são utilizados pelo adenovírus durante a sua replicação, mas que o seu papel é diferencial, com relevo inesperado para as topoisomerases IIα e IIβ. Estes resultados sugerem que as topoisomerases poderão ser potenciais alvos na terapêutica de patologias infecciosas e potenciais factores preditivos na terapêutica viral do cancro.
Gunhan-Senol, Nazmiye Evra. ""I'm Turkish, I'm Honest..." I'm Autistic| Perceptions Regarding the Label of Autism." Thesis, University of Louisiana at Lafayette, 2015. http://pqdtopen.proquest.com/#viewpdf?dispub=3712371.
Повний текст джерелаThis dissertation focused on understanding the perceptions built around autism in the Turkish context through an inquiry of lived experiences of individuals who have close contact with individuals on the autism spectrum. The nature of the experiences of two main groups of the participants, a group of experts working with individuals with autism and the parents of children who are on the spectrum, is explored employing an interpretive phenomenological analysis, which is a method of qualitative inquiry. The perceptions of participants show divergences and similarities regarding the nature of autism, the intervention, and the role of the family as well as regarding issues about diagnosis, collaboration, and conflict among experts and between all participant groups. For all groups of participants, the variation in the manifestations of autism symptomology and the overall severity level emerged as one crucial factor shaping the perceptions around the condition. The understandings of the majority of the participants seems to be informed by a theoretical basis that is mainly built around behavior control and behavior modification. The emphasis on behavior modification, in turn, shapes the education practices, which is considered to be the sole intervention for autism by all participants, leading to efforts to eliminate unwanted behaviors rather than seeking the possible underlying factors that trigger them. The focus on behaviors also leads to a particular understanding of what constitutes a successful outcome of therapy in which the evaluation of functional use of skills acquired during intervention can be overlooked.
The informational inaccessibility and the knowledge inequality that currently exists in Turkey appears as one major implication of this investigation. This is indicative of the need for greater collaboration on the part of the professionals as well as a service delivery system that is oriented to providing parents and experts working with children on the ASD spectrum with the most recent data-based knowledge.

Повний текст джерелаEn esta Memoria de Título se estudió la extracción y separación de lantano (III), cerio (III), praseodimio (III) y neodimio (III) mediante extracción por solventes utilizando como agentes transportadores los extractantes comerciales D2EHPA, PC88A, LIX 272 y CYANEX 301. El análisis de las curvas de especiación química de los elementos tierras raras (ETR) en fase acuosa en función del pH permiten establecer que en el rango de pH de trabajo los iones de La, Ce y Pr se encuentran principalmente como iones complejados con nitrato. Sin embargo, entre pH 1 y 2 se presenta una competencia con la especie ETR-sulfato. Debido a que el ión nitrato presenta un poder ligante muy débil, en la práctica es posible considerar que los iones ETR se encuentran como especies libres cuando se presenta una competencia frente a un ligante más fuerte, tal como sería en el caso de los extractantes organofosforados, mientras que, la especie ETR-sulfato sería la única especie que podría interferir en la extracción de los iones de ETR. Los experimentos de extracción por solventes realizados entre cada uno de los iones metálicos de ETR con cada uno de los extractantes propuestos, se llevaron a cabo considerando las siguientes variables que afectan al proceso: la concentración de cada uno de los extractantes en la fase orgánica, de cada ión metálico presente en la fase acuosa y el pH de la solución acuosa de alimentación. Un análisis de los resultados obtenidos para la variación en la concentración de extractante indicó que, los valores más altos de extracción se logran cuando se utilizan 40 mM. Los resultados varían dependiendo del ión metálico observándose siempre las mayores extracciones para Pr, y en menor grado consecutivo Nd, Ce y La. Los resultados obtenidos para la variación de pH inicial indicaron que, en general, el porcentaje de extracción se incrementa con el aumento del pH inicial de la solución acuosa de alimentación en todos los experimentos realizados. En el caso de los extractantes D2EHPA y PC88A se alcanzaron extracciones sin una distinción práctica entre cada uno de los iones ETR. Mientras que, en el caso de los extractantes LIX 272 y CYANEX 301 se observó que hay diferenciación clara en el grado de extracción para los distintos ETR. Los resultados obtenidos para la variación en la concentración de ión metálico inicial permitieron aseverar que, en general, el grado de extracción disminuye con el incremento de la concentración de ión metálico en la solución de alimentación inicial para los cuatro extractantes estudiados. Los experimentos de retroextracción de los iones metálicos de ETR presentaron una tendencia moderada a la disminución con el incremento de la concentración de H2SO4 en la fase acuosa para los todos los complejos ETR-extractante estudiados. Sólo se observó que en el caso de los complejos ETR-LIX 272 se lograron porcentajes de retroextracción intermedios que podían ser utilizados en una ruta de separación de los iones ETR. El análisis de los estudios de equilibrio permitió apreciar claramente que la extracción de Pr es la más favorecida en todos los casos, y en menor grado consecutivo Nd, Ce y La. Adicionalmente, se pudo observar que desde el punto de vista de los extractantes el D2EHPA es el que más favorece la reacción de extracción y en menor grado consecutivo PC88A, LIX 272 y CYANEX 301. A partir de un análisis de todos los datos obtenidos se pudo deducir que el extractante LIX 272 cumplió de mejor manera con el requisito de extraer preferentemente alguno de los iones de ETR en ciertas condiciones y, de este modo, poder plantear de esa manera alguna posible ruta de separación. Los estudios cinéticos de extracción indicaron que en general es el Pr el que reacciona más rápidamente, y el La el que reacciona más lentamente, con todos los extractantes. Del mismo modo, se observa que el extractante que reacciona de manera más rápida con los iones metálicos es el D2EHPA y en menor grado consecutivo PC88A, LIX 272 y CYANEX 301. Por otro lado, los experimentos cinéticos de retroextracción indicaron que los complejos ETR-D2EHPA y ETR-PC88A son los que más rápidamente liberan los iones de ETR. Asimismo, el complejo ETR-CYANEX 301 es el que los libera más lentamente. La ruta de separación de iones metálicos en dos etapas propuesta en este estudio utilizando como extractante el LIX 272 cumple en cierta medida con el objetivo planteado. En la primera etapa de extracción se logró incrementar la pureza del La en la fase acuosa hasta un 40%, aproximadamente. Una proyección de este resultado en 8 contactos permitiría obtener un refino constituido exclusivamente por La, alcanzando a aislar cerca del 70% del La inicial. En la segunda etapa de la ruta de separación, que considera la retroextracción de los complejos ETR-LIX 272, se logró aislar cerca del 74% del Ce inicial con una pureza superior al 98%. Una proyección de 3 contactos para esta etapa permitiría obtener una fase acuosa final con un 99,97% de pureza de Ce y con un rendimiento global del proceso de un 54,8%. Esta ruta de separación por equilibrios deja el problema de separación relegado solamente a la dupla Pr y Nd. Por otro lado, la diferencia en un orden de magnitud de las constantes cinéticas de retroextracción para los complejos Pr-LIX 272 y Nd-LIX 272 permitiría proyectar una separación de ambos iones en el tiempo
The extraction and separation of lanthanum (III), cerium (III), praseodymium (III), and neodymium (III) was studied by means of solvent extraction using D2EHPA, PC88A, LIX 272, and CYANEX 301 as extractant. The analysis of the chemical speciation curves of rare earth elements (REE) in aqueous phase as a function of pH allow to establish that in the working pH range the lanthanum, cerium, and praseodymium ions are complexed mainly with nitrate. However, between pH 1 and 2 a competition with REE-sulfate species is observed. Due to the nitrate ion has a very weak binding power, in fact it is possible to consider that REE ions are as free species when there is a competition with a stronger binder, as would be the case of organophosphorus extractants, while REE-sulfate species would be the only species that could interfere in the extraction of REE ions. The solvent extraction experiments, performed between each of the metal ions of REE with each of the proposed extractants, were carried out considering the following variables that affect the process: the concentration of each of the extractants in the organic phase, the concentration of each metal ion present in the aqueous phase and the pH of the aqueous feed solution. An analysis of the obtained results for the variation in the extractant concentration indicated that the highest values of extraction are achieved when using 40 mM. Results vary depending on the metal ion, always showing a preference for the praseodymium and in less consecutive degree for neodymium, cerium, and lanthanum. The obtained results for the variation of initial pH indicated that, in general, the extraction percentage increases with rising initial pH of the aqueous feed solution in all experiments. While in the case of extractants D2EHPA and PC88A no practical distinction between each of the REE ions were achieved, in the case of extractants LIX 272 and CYANEX 301 it was noted that there was clear difference in the degree of extraction for different REE. The results obtained for the variation in initial metal ion concentration allowed to assert that, in general, the extraction degree decreases while increasing metal ion concentration in the initial feed solution for the four extractants studied. Stripping experiments of REE metal ions showed a moderate tendency to decrease with increasing H2SO4 concentration in the aqueous phase for all REE-extractant complexes studied. It was observed that only in the case of REE-LIX 272 complex intermediate stripping percentages were achieved that could be used in a route of the separation of REE ions. The analysis of the equilibrium studies allowed to appreciate clearly that the extraction of praseodymium is the most favored in all cases, and less consecutive neodymium, cerium and lanthanum. Additionally, it was noted that from the point of view of the extractants, D2EHPA is which most favors the extraction reaction and in less consecutive degree for PC88A, LIX 272, and CYANEX 301. From an analysis of all the obtained data it is allowed to conclude that extractant LIX 272 is which better complies with the requirement for removing any REE ions preferably under certain conditions and, thus, can propound some possible separation route. Extraction kinetic studies indicated that in general praseodymium will react faster with all the extractants and also in general, lanthanum reacts more slowly. In the same way, it is noted that the extractant that react faster with the metal ions is D2EHPA and in less consecutive degree for PC88A, LIX 272, and CYANEX 301. Furthermore, stripping kinetic experiments indicated that REE-D2EHPA, and REE-PC88A complexes are the fastest in releasing REE ions. Likewise, REE-CYANEX 301 complex is that which release them more slowly. The separation route of metal ions in two stages proposed in this study using the LIX 272 extractant fulfill in some extent with the stated objective. In the first extraction step it was able to increase the purity of lanthanum in the aqueous phase up to 40%, approximately. A projection of this result for 8 contacts would obtain a refine constituted exclusively of lanthanum, reaching out to isolate about 70% of the original lanthanum. In the second stage of the separation route, that considers the stripping of REE-LIX 272 complexes, about 74% of the initial cerium was isolated with a purity exceeding 98%. A projection of 3 contacts for this stage would provide a final aqueous phase with a purity of 99.97% for cerium and an overall process yield of 54.8%. This equilibrium separation route leaves the separation problem relegated only to the couple praseodymium and neodymium. On the other hand, the difference in an order of magnitude of the stripping kinetic constants for Pr-LIX 272, and Nd-LIX 272 complexes would allow to project a separation of both ions at time

Повний текст джерелаENGLISH ABSTRACT: Ruthenium, as one of the platinum group metals, was investigated to determine the aquation rate constant of [RuCl6]3- and the anation rate constant of [RuCl5(H2O)]2-. This two reactions represent the equilibrium reaction [RuCl6]3- + H2O ⇄ [RuCl5(H2O)]2- + Cl-. The reactions were followed, using stopped-flow injection and UV/Visible spectroscopy, at different temperatures. The aquation and anation rate constants were determined with good precision and thermodynamic values for the reactions were calculated. The pseudo first order aquation rate constant, k65, was determined by calculation from the regression line as k65 = 52.1 (±3.7) x10-3 s-1 at 25°C. The activation energy, Ea, is 90.1 (±1.2) kJ.mol-1 and the enthalpy and entropy of activation is 87.7 (±1.2) kJ.mol-1 and 24.7 (±4.3) J.K-1.mol-1, respectively. The aquation rate constant was found to be dependent on the hydrochloric acid concentration, decreasing with increasing hydrochloric acid concentration. From the regression line at 25°C the second order anation rate constant, k56, was calculated as 1.62 (±0.11) x10-3 M-1s-1. The activation energy is 88.0 (±1.4) kJ.mol-1, with the enthalpy and entropy of activation 85.6 (±1.4) kJ.mol-1 and –11.2 (±4.7) J.K-1.mol-1, respectively. The influence of the hydrochloric acid concentration of the solution on the anation rate constant was not investigated. The equilibrium constant for the reaction studied was calculated from the rate constants for the aquation and anation reactions. The equilibrium constant, K6, was calculated as 0.0311 M-1 at 25°C. The equilibrium constant, when compared to literature, was found to be dependent on the hydrochloric acid concentration. It was then used, in conjunction with data from the literature, to construct two distribution diagrams. Distribution diagrams for the Ru(III) aquachloro species show between 79.9% to 72.3% [RuCl6]3- present in 12M HCl. The two distribution diagrams were very similar and it is not possible to resolve the issue of a final distribution diagram for the aqua-chloro Ru(III) system without further investigation into the all the other rate constants of the Ru(III) aqua-chloro species. The rate constants and thermodynamic values for the Ru(III) reaction were compared to corresponding data (from literature) for Rh(III) and Ir(III) because several comparisons between these platinum group metals have been noted. It was found that for both the aquation and anation rate constants, the following trend was observed: Ru(III) > Rh(III) > Ir(III). These differences are in certain cases exploited in the refining of these platinum group metals. Crystals of diethylenetriamine hexachlororuthenate(III) was prepared and characterised by x-ray crystallography and CHN analysis. The average Cl-Ru bond length for the crystal was 2.371 Å. The crystal structure was compared to hexaaquaaluminium hexachlororuthenate(III) tetrahydrate and diethylenetriamine hexachlororhodate(III). The metal-chloride bond lengths of all the crystals were found to be similar (2.350 Å – 2.375 Å). The diethylenetriamine crystal structures compared well. The conclusion was that the crystals prepared were diethylenetriamine hexachlororuthenate(III).
AFRIKAANSE OPSOMMING: Ruthenium(III), een van die platinum groep metaal-ione, is in hierdie studie ondersoek om die akwasie tempo konstante van [RuCl6]3- en die anasie tempo konstante van [RuCl5(H2O)]2- te bepaal. Dié twee reaksies verteenwoordig die ewewigsreaksie [RuCl6]3- + H2O ⇄ [RuCl5(H2O)]2- + Cl-. Die verloop van die reaksies is met behulp van UV/Sigbare spektroskopie by verskillende temperature gevolg. Die akwasie en anasie tempo konstantes is bepaal met goeie presisie en die termodinamiese konstantes van die reaksies is bereken. Die pseudo-eerste orde akwasie tempo konstante, k65, is bepaal deur middel van regressie, as 52.1 (±3.7) x10-3 s-1 by 25°C. Die aktiverings energie, Ea, is bereken as 90.1 (±1.2) kJ.mol-1 en die entalpie en entropie van aktivering is onderskeidelik 87.7 (±1.2) kJ.mol-1 en 24.7 (±4.3) J.K-1.mol-1. Daar is gevind dat die akwasie reaksie konstante afhanklik was van die soutsuur konsentrasie: dit neem af soos die soutsuur konsentrasie toeneem. Met behulp van die regressie lyn is die anasie tempo konstante bepaal by 25°C as 1.62 (±0.11) x10-3 M-1s-1. Die aktiveringsenergie is bepaal as 88.0 (±1.4) kJ.mol-1 en die entalpie en entropie van aktivering, onderskeidelik as 85.6 (±1.4) kJ.mol-1 en –11.2 (±4.7) J.K-1.mol-1. Die invloed van die soutsuur konsentrasie op die anasie tempo konstante is nie bepaal nie. Die ewewigskonstante vir die reaksie wat ondersoek is, is bereken met die tempo konstantes vir die akwasie en anasie reaksies. Die ewewigskonstante, K6, is bereken as 0.0311 M-1 by 25°C. Toe die ewewigskonstante vergelyk is met die literatuur waardes, is gevind dat die ewewigskonstante afhanklik is van die soutsuur konsentrasie. Saam met die waardes wat in die literatuur gevind is, is die ewewigskonstante gebruik om twee distribusie diagramme te bereken. Die distribusie diagramme vir die Ru(III) spesies toon onderskeidelik 79.9% en 72.3% [RuCl6]3- in 12M HCl. Die twee distribusie diagramme is baie eenders en dit is nie moontlik om ‘n finale distribusie diagram op te trek totdat die uitstaande tempo konstantes tussen die akwachloro Ru(III) spesies bepaal word nie. Die tempo konstantes en termodinamiese waardes wat bepaal is vir die Ru(III) reaksie is vergelyk met gelyksoortige waardes in die literatuur van Rh(III) en Ir(III) omdat daar ooreenkomste tussen die platinum groep metale opgemerk is. Daar is bevind dat die akwasie én anasie reaksies die volgende patroon volg: Ru(III) > Rh(III) > Ir(III). Die verskille word in sekere gevalle benut in die raffinering van hierdie metale. Kristalle van dietileentriamien heksachlororuthenaat(III) is berei en gekarakteriseer met behulp van CHN analise en x-straal kristallografie. Die gemiddelde Cl-Ru bindingsafstand vir die kristal was 2.371 Å. Die kristalstruktuur is vergelyk met dié van heksaäkwaäluminium hexachlororuthenaat(III) tetrahidraat en diëtileentriamien heksachlororhodaat(III). Die chloried-metaal bindingsafstand vir die kristalle was soortgelyk (2.350 Å – 2.375 Å). Die diëtileentriamien kristalstrukture stem goed ooreen. Die gevolgtrekking was dat die kristalle wat voorberei is wel diëtileentriamien heksachlororuthenaat(III) was.

Повний текст джерелаEn esta Memoria de Titulo se estudió la transferencia del lantano (III), cerio (III), praseodimio (III) y neodimio (III), desde una fase acuosa de alimentación hacia una fase acuosa de retroextracción, por medio del transportador órgano fosforado CYANEX 272 contenido en una membrana liquida emulsificada. En primera instancia se estudió el comportamiento ácido base de cuatro extractantes (D2EHPA, PC-88A, CYANEX 272, CYANEX 301) permitiendo conocer sus pKa aparentes y su disponibilidad para reaccionar con los iones Tierras Raras (TR) a ciertos pH. A partir de este conocimiento y las reacciones de extracción propiamente tales fue posible proponer la utilización de una fase acuosa de alimentación tamponada con el ácido 3-cloropropiónico a pH 4. A través de los experimentos de extracción por solvente de cada uno de los iones TR con los cuatro extractantes en estudio, se determinó que el extractante más adecuado para el proceso fue el CYANEX 272, debido a su alta capacidad de extracción y mayor selectividad con los cuatro iones TR. Si bien en un principio todos los experimentos se realizaron con alimentaciones monometálicas, después fue preciso probar el grado de competencia que se generaría al realizar la extracción de los iones lantánidos desde una alimentación polimetálica. Los resultados fueron coincidentes con los experimentos de extracción individuales de los iones TR, en donde el lantano es el ión que menos se extrajo en comparación con los otro tres. Por otro lado, los experimentos de retroextracción revelaron que ion cerio presentaba el menor grado de transferencia hacia la fase acuosa interna. Todos estos conocimientos generados revelaron que la dupla Nd-Pr era difícil de separar con las condiciones ya establecidas. Por esta razón se agregó EDTA como agente quelante a una alimentación que contenía estos dos iones en iguales concentraciones (2mM), lográndose un coeficiente de selectividad máximo (SPr/Nd) de 1,7. Los experimentos de extracción por solvente (SX) generaron el conocimiento base para los experimentos de transporte de los cuatro iones lantánidos con CYANEX 272 a través de las Membranas Líquidas Emulsificadas (MLE). Previo al inicio de los experimentos de transferencia fue necesario lograr una doble emulsión de estabilidad adecuada en función de las concentraciones variables de sus componentes: transportador CYANEX 272, tensoactivo SPAN 80, Ln+3 (lantánidos) total y HCl en la fase acuosa de retroextracción. A partir del estudio de estabilidad, se observó que la concentración del tensoactivo SPAN 80 presentó el efecto más crítico, donde una cantidad insuficiente produjo pérdida de la fase acuosa interna, disminuyendo el rendimiento de extracción. Por otro lado, una cantidad excesiva de SPAN 80 provocó el hinchamiento de la emulsión primaria. Como consecuencia de esto la fase acuosa interna que contiene al ion de interés se diluye o pierde pureza. En términos generales, para conservar el volumen de 75 mL de emulsión primaria, formada por 25 mL de fase acuosa interna más 50 mL de fase orgánica, es necesario utilizar alrededor de 1,2% p/v de SPAN 80, cuando la concentración en la alimentación de cada uno de los ETR es 0,5 mM. Para concentraciones mayores se necesita aproximadamente entre 2-2,1% p/v de tensoactivo. Con los experimentos preliminares de transferencia de los iones TR en estudio, se pudo determinar que los elementos lantano, cerio, praseodimio y neodimio fueron extraídos eficientemente en el orden del 90% desde la alimentación, mientras que fueron transportados a través de la membrana hacia la fase acuosa interna en un rango entre 40-60%. Posteriormente, un estudio cinético de la extracción de cada uno de los ETR, permitió observar que durante los primeros 5 min los iones cerio, praseodimio y neodimio experimentaron un rápido decaimiento en su concentración en la fase acuosa externa, mientras que para el ion lantano se requirió al menos de 10 min. Finalmente, para lograr un enriquecimiento de cada uno de los iones metálicos mediante MLE desde una solución polimetálica, se realizaron dos diseños experimentales, uno de tipo screening y otro de optimización. Los resultados del primer diseño indicaron que el factor tiempo fue el único que presentó un efecto significativo sobre los porcentajes de extracción y transferencia de los ETR a través de la doble emulsión. En el segundo diseño los resultados indicaron que la presencia de EDTA en la fase acuosa externa tuvo un efecto negativo sobre el grado de transferencia de los iones TR hacia la fase orgánica.
In this work the transference of lanthanum (III), cerium (III), praseodymium (III) and neodymium (III) were studied, from a feed aqueous phase toward a backextraction aqueous phase by means of the organophosphorous CYANEX 272 carrier contained into an emulsified liquid membrane. In the first instance the acid-base behavior of the four extractants (D2EHPA, PC-88A, CYANEX 272 and CYANEX 301) were studied allowing to know their apparent pKa and through it the availability to react with the rare earth ions (RE) at certain pH. From this knowledge and the actual such extraction reactions it was possible to propose the use of a buffered feed aqueous phase with 3-cloropropionic acid at pH 4. Through the solvent extraction experiments for each one of the RE with the considered four extractants, it was determined that the most appropriated extractant for the process was CYANEX 272, owing to its high extraction capacity and better selectivity for the four RE ions. Although at first all experiments were performed with monometallic feeds, afterward it was necessary to test the degree of competition that would be generated to perform the extraction of lanthanide ions from a polymetallic feed solution. The results were consistent with the individual extraction experiments of the RE ions, wherein lanthanum is the lesser extracted ion compared with the other three ones. On the other hand, the backextraction experiments showed that the cerium ion had the lowest degree of transference toward the internal aqueous phase. All this generated knowledge revealed that the pair Nd-Pr was difficult to separate at the established conditions. For this reason, EDTA as a chelating agent was added to the feed solution that contained these two ions at identical concentrations (2 mM), achieving a maximum selectivity coefficient (SPr/Nd) of 1.7. The solvent extraction (SX) experiments generated the base knowledge for the transport experiments of the four lanthanide ions with CYANEX 272 through Emulsified Liquid Membranes (ELM). Before starting the transfer experiments it was necessary to achieve a satisfactory stability of the double emulsion as a function of the variation of the component concentrations: carrier CYANEX 272, surfactant SPAN 80, total Ln3+ (lanthanides) and HCl in the backextraction aqueous phase. From this stability study it was observed that the concentration of SPAN 80 surfactant showed the most significant effect, where an insufficient amount caused the loss of the internal aqueous phase, decreasing the efficiency of extraction. On the other side, an excessive amount of SPAN 80 caused a swelling degree of the primary emulsion. As a consequence the internal aqueous phase that contains the ion of interest is diluted or lost its purity. In general terms, for keeping the volume of 75 mL of the primary emulsion, consisting of 25 mL of internal aqueous solution plus 50 mL of the organic solution, it is necessary to use about 1.2% w/v of the SPAN 80, when the concentration of each the REE in the feeding is 0.5 mM. For higher concentrations of the total REE about 2 to 2.1% w/v of surfactant are needed, approximately. From the preliminary experiments related with the transfer study of the RE ions, it was determined that the lanthanum, cerium, praseodymium and neodymium elements are removed efficiently in the order of 90% from the feed solution, while they were transported across the membrane toward the internal aqueous phase in the range of 40-60%. Afterward, a kinetic study of the extraction of each one of the REE, allowed to note that during the first 5 min of the carrying out tests the cerium, praseodymium and neodymium ions experimented a fast decline in the concentration in the external aqueous phase, whereas for the ion lanthanum at least 10 min was required. Finally, to achieve an enrichment of each one of the metal ions from a polymetallic solution by means MLE, two experimental designs were conducted, a screening one and another one related with the optimization type. The results of the first design indicated that the time factor was the unique significant effect on the extraction and transfer rates of the REE through the double emulsion. In the second design the results indicated that the presence of EDTA in the external aqueous phase has a negative effect on the transfer degree of the RE ions towards the organic phase.

Richard III is regarded as one of Shakespeare's longest and most complex plays, with a complicated plot, and a character that is a Machiavellian villain. After a workshop of Act I as an MFA Directing Project, I was granted by Temple University to stage a full production of Richard III as my thesis. Approaching the play proved difficult for me due to my lack of experience with Shakespearean text. However, by analyzing Shakespeare's text, and approaching the adaptation with the goal to make the story as clear as possible, I desired to create a production that embodied the idea of "now." The designed team and I created a world that was a-historic pulling from classic and modern forms that provided the necessary landscape for the play to occur. Through a series of seven chapters I explain my process from conception to production. I also evaluate my growth as a director during this artistic achievement. A Director's Script, Actor's Lexicon, Program Note, Design Renderings and Production Photos support my journey to opening night of Richard III.

Повний текст джерелаA lagarta-do-cartucho, Spodoptera frugiperda (J. E. Smith 1797) (Lepidoptera: Noctuidae), é considerada o principal inseto-praga da cultura do milho no Brasil. Seu controle, nos últimos anos, é realizado principalmente por meio do uso de plantas Bt e pulverização de inseticidas. Visando avaliar a eficiência das proteínas Bt expressas pelos milhos disponíveis no mercado, bem como sua interação com o uso de inseticidas para o controle de S. frugiperda para subsidiar programas de MIP e MRI em milho Bt, foram realizados experimentos, em condição de campo, durante duas épocas de cultivo na safra 2015-16. Foram avaliadas oito tecnologias de milho Bt e um híbrido não-Bt, bem com sete programas de aplicação de inseticidas. A cada cinco dias, foram realizadas avaliações de dano, contabilizando o número de plantas danificadas e atribuindo uma nota de acordo com a Escala de Davis (1992). Para a aplicação dos inseticidas, foi estabelecido um nível de controle em que era realizada a pulverização sempre que 10% das plantas apresentassem nota de dano >3. Na 1a safra 2015/16, Agrisure TL (Cry1Ab), Herculex (Cry1F) e Optimum Intrasect (Cry1Ab/Cry1F) e milho não-Bt necessitaram de 1 a 3 pulverizações de inseticidas para complementar o controle de S. frugiperda. Nesta safra, todos os inseticidas testados foram eficientes no controle. Já em milho YieldGard VT PRO (Cry1A.105/Cry2Ab2), YieldGard VT PRO 3 (Cry1A.105/Cry2Ab2/Cry3Bb1), PowerCore (Cry1A.105/Cry2Ab2/ Cry1F), Agrisure Viptera (Vip3Aa20) e Agrisure Viptera 3 (Vip3Aa20/Cry1Ab) não foi necessário o uso de inseticidas. Na 2a safra 2015/16, com exceção de Agrisure Viptera e Agrisure Viptera 3, todos as demais híbridos de milho Bt e não-Bt necessitaram de 1 a 4 pulverizações de inseticidas. Os resultados obtidos no presente trabalho demonstram que algumas tecnologias de milho Bt (expressando genes que codificam proteínas Cry1) apresentam baixa eficiência de controle, tornando-se assim indispensável o uso de inseticidas para complementar o controle de S. frugiperda. Em contraste, a proteína Vip3Aa20 apresenta alta toxicidade para S. frugiperda, apresentando danos insignificantes à cultura. Dentre os inseticidas testados no trabalho, spinetoram (12 g de i.a./ha), de modo geral apresentou a maior eficiência de controle para lagarta-do-cartucho.

Повний текст джерелаThe preoperative characterization of adnexal tumors is crucial for surgical care. Dynamic contrast enhanced MR imaging (DCE-MRI) allows an optimization of the tissue characterization. Adnexal tumors differ according to their dynamic curve enhancement, which reflect the immaturity of the vascular wall and the expression of VEGFR-2 on endothelial cells. For a quantitative analysis of enhancement, a turbo-FLASH sequence with high angles is better to get both optimal dynamic enhancement range and an almost linear relationship between the signal and the concentration of gadolinium. Initialization by a extended Kéty model stabilizes our two-compartmental model which allows the best description of exchanges between the capillary and the interstitial spaces. Using quantitative DCE MRI, malignant adnexal tumors display higher tissue perfusion and blood volume fraction than benign tumors. Finally, quantitative DCE-MRI is a suitable, non-invasive tool to assess physiological microvascular states and variations in normal myometrium, and could potentially be used to assess the role of the inner myometrium in assisted reproductive therapy
