    Full Text Available Se presenta un caso de intoxicación mortal por ingestión del raticida Brodifacum, un anticoagulante superwarfarínico, junto con otros fármacos, entre los que se incluían antiinflamatorios no esteroideos y un disolvente orgánico de uso doméstico. El sujeto falleció en la UCI, con un cuadro de insuficiencia respiratoria aguda, seguida de fallo hepático y renal. En la autopsia se pusieron de manifiesto lesiones hemorrágicas circunferenciales que afectaban a diversos tejidos, entre los que se encontraban la grasa mesentérica, el epicardio, y la grasa perirrenal. El estudio microscópico demostró la existencia de una típica lesión hemorrágica aguda, circunferencial, en los nervios vegetativos epicárdicos y del área del esplácnico. La explicación de porqué los nervios periféricos vegetativos se constituyen en diana de los efectos tóxicos se atribuye a la acción combinada de los disolventes y de los anticoagulantes, sobre el sistema nervioso periférico. Se sabe que los disolventes orgánicos producen una lesión neuronal aguda, consistente en tumefacción axonal y del soma neuronal, que conlleva a la alteración del sistema de transporte a lo largo del axón. Creemos que -desde el punto de vista fisiopatológico- la vasodilatación reactiva de los vasa nervorum, producida a consecuencia de la lesión neuronal aguda inducida por los disolventes, unida al estado de hipocoagulabilidad sanguínea -dependiente de la ingestión de Brodifacum (superwarfarina y potenciada por los antiinflamatorios no esteroideos- constituyen los mecanismos íntimos que podrían explicar esta peculiar Neuropatía Hemorrágica Aguda Tóxica de los nervios periféricos del Sistema Nervioso Neurovegetativo. Desconocemos si los nervios periféricos mixtos se encontraban afectados por esta lesión, al carecer de muestras para un estudio definitivo.In this paper we describe a case of mortal poisoning by ingestion of the rodenticide Brodifacoum, a superwarfarin

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Com o uso de anticoagulantes para tromboprofilaxia, a incidência de hematomas em anestesias espinhais aumentou. O objetivo desta revisão é verificar a ocorrência de casos de hematomas espinhais e sua correlação com o uso de drogas utilizadas na tromboprofilaxia. CONTEÚDO: São feitas algumas considerações clínicas e farmacológicas sobre as drogas utilizadas em tromboprofilaxia (cumarínicos, aspirina e heparina. São ressaltados os fatores de risco, particularmente aos relatos de casos de pacientes que desenvolveram hematoma peridural decorrente do uso simultâneo de heparina de baixo peso molecular e anestesia peridural. CONCLUSÕES: Existe importante associação entre hematoma peridural e distúrbios hemorrágicos, principalmente em pacientes em tratamento com anticoagulantes. O reconhecimento do aumento do risco da associação da anestesia peridural, da anestesia subaracnóidea, a continuada vigilância e a educação são fundamentais para evitar futuros casos.

    Full Text Available Uma pesquisa exploratória de natureza qualitativa e quantitativa foi realizada durante o período de maio a agosto de 2013 no Laboratório de Análises Clínicas do Hospital das Clínicas localizado no município de Itaperuna, RJ. O objetivo foi analisar o perfil dos pacientes sob tratamento com anticoagulantes, demonstrando as potenciais variações nos valores da Relação Normalizada Internacional (RNI em comparação aos valores de referência bem como a frequência de realização de tais exames. Um questionário foi aplicado pouco antes da coleta do sangue, estabelecendo-se como critério de inclusão o uso de medicamentos anticoagulantes. Os resultados indicaram um total de 45 pacientes sob tratamento com anticoagulantes, sendo 32 do sexo feminino e 13 do sexo masculino. A maioria dos pacientes encontrava-se sob tratamento com o anticoagulante de uso oral varfarina e se encontrava com idade superior a 50 anos. O valor médio do RNI apresentou-se dentro dos limites considerados seguros, porém mais da metade dos pacientes apresentou RNI < 2,0 e a maioria dos pacientes sob tratamento com anticoagulantes não realiza a avaliação do RNI com frequência.

    Full Text Available Se determinó la presencia de residuos de rodenticidas anticoagulantes por cromatografía de líquidos acoplada a espectrometría de masas de triple cuadrupolo en el hígado de 61 aves rapaces muertas provenientes del Centro de Recuperación de Fauna Silvestre de Tafira (Gran Canaria, pertenecientes a 5 especies de las 11 presentes en el archipiélago canario. Se encontraron residuos en 42 animales (69% si bien en sólo 1 de ellos se consideró la intoxicación por rodenticidas como causa primaria de muerte, según los datos clínicos, analíticos y de necropsia. De las rapaces estudiadas, fueron las especies Tyto alba y Accipiter nisus las que más frecuentemente presentaron residuos de anticoagulantes (85% y 89% respectivamente. Se detectaron residuos de 5 anticoagulantes, todos ellos de segunda generación, siendo la bromadiolona las más frecuentemente detectada, seguida del brodifacoum y del difenacoum. Un elevado número de las muestras positivas (63% presentó más de un residuo de anticoagulantes en su hígado, habiéndose encontrado mezclas de hasta 4 productos diferentes. Llamó la atención que la mayoría de los animales que ingresaron en el centro de recuperación por politraumatismo por colisión presentaba residuos de uno o varios anticoagulantes, así como que rapaces que se alimentan principalmente de pájaros también presentaron frecuentemente residuos de estos compuestos. Los resultados de este estudio sugieren que el elevado uso de rodenticidas anticoagulantes en el medio natural implica su incorporación a la cadena trófica, viéndose afectadas especies de fauna silvestre en las que estos productos podrían producir efectos adversos. Esto implica que la aplicación de rodenticidas anticoagulantes en espacios abiertos supone una amenaza para el estado de conservación de la biodiversidad de las Islas Canarias.

    Full Text Available Justificación: los anticoagulantes orales requieren una estricta farmacovigilancia; describir y analizar la utilización de estos medicamentos es importante para editar guías, recomendaciones y advertencias ante el uso de esta terapia, y así brindar al personal médico una herramienta de apoyo para su adecuada utilización. Métodos: se seleccionaron pacientes a quienes durante su estancia hospitalaria se les prescribiera algún anticoagulante oral. Se recolectó la información específica que facilitara el análisis. Para validar lo recopilado se utilizaron las guías del Colegio Americano de Cirujanos Torácicos y las guías americanas y europeas de los colegios de cardiología. Resultados: se recopiló la información de un total de 176 pacientes. Los especialistas que prescriben estos medicamentos son ortopedistas (40%, internistas (14%, cardiólogos (13% e intensivistas (11%, para el tratamiento de tromboprofilaxis de accidente cerebrovascular, tromboprofilaxis postoperatoria, tratamiento del tromboembolismo pulmonar y de trombosis venosa profunda; el 84% de los pacientes que usó estos medicamentos, lo hizo en indicaciones aprobadas. Se reportó un 3,4% de sangrados. Conclusión: la mayoría de las prescripciones se realizaron de acuerdo con lo establecido por las guías; a pesar de esto, existe una evidente incongruencia con respecto a los exámenes solicitados y su monitorización. La mayor proporción de los sangrados reportados se asoció a warfarina; aún así, seguirá siendo el estándar para el manejo de este tipo de pacientes, hasta que se apruebe tratamientos de reversión para los nuevos anticoagulantes y métodos adecuados para su monitorización, en los casos que se requiera.

    Full Text Available Los especialistas en dolor crónico nos enfrentamos habitualmente a situaciones en las que los pacientes que van a ser sometidos a procedimientos intervencionistas están bajo tratamiento antiagregante o anticoagulante. Las complicaciones hemorrágicas pueden ser catastróficas cuando se trata de bloqueos profundos y técnicas dentro del canal espinal. Sin embargo, el riesgo de eventos tromboembólicos aumenta con la suspensión inadecuada de los fármacos antiagregantes y anticoagulantes en estos pacientes. A día de hoy no existen unos algoritmos o recomendaciones actualizadas para el manejo de estos pacientes en el área de dolor crónico. El objetivo de este documento es ofrecer unas recomendaciones de seguridad sobre el manejo de estos fármacos según el tipo de intervención y el tipo de paciente, con el objetivo de minimizar el riesgo de complicaciones hemorrágicas sin aumentar el riesgo de eventos tromboembólicos. Para ello, se han revisado las últimas publicaciones sobre el manejo fármacos que alteran la hemostasia en anestesia regional y otras técnicas de dolor crónico, incluyendo diferentes guías de manejo perioperatorio (ASRA, ESA, SEDAR.... Existe buena evidencia en el incremento del riesgo de eventos tromboembólicos en pacientes que suspenden la terapia antiagregante, y que este riesgo es mayor que el de la incidencia de hematomas epidurales en pacientes que continúan con el tratamiento, si bien ambos riesgos son significativos. Así mismo, existe buena evidencia de la incidencia de hematomas epidurales espontáneos asociados o no a punción traumática, en pacientes con o sin terapia antitrombótica. Estos hematomas epidurales espontáneos están asociados a factores favorecedores como la manipulación excesiva, el uso de agujas de mayor calibre, el uso de catéteres, los procedimientos sobre el canal cervical, la edad avanzada, y las anormalidades vasculares y anatómicas del paciente.

    Full Text Available El dabigatrán es un nuevo inhibidor directo de la trombina, de administración oral, empleado para la prevención de eventos tromboembólicos en pacientes con fibrilación auricular no valvular. A diferencia de la warfarina, no se dispone de un antídoto conocido. La hemodiálisis ha sido sugerida como un método para remover el dabigatrán y reducir el efecto anticoagulante. Se presenta el caso de un paciente con antecedente de fibrilación auricular y medicado con dabigatrán, que fue admitido en el hospital para una cirugía abdominal de urgencia. A las seis horas de la última dosis recibida, los estudios de coagulación mostraban alteración. Ante la falta de antídoto para revertir los efectos, se decidió realizar hemodiálisis. Luego de tres horas de diálisis los parámetros de coagulación tendieron a normalizarse y el paciente fue operado sin presentar hemorragias anormales durante la cirugía o en el postoperatorio.

    2010-01-01

    In this paper,the effects of thickness of AIN nucleation layer grown at high temperature on AIN epi-layer crystalline quality are investigated.Crack-free AIN samples with various nucleation thicknesses are grown on sapphire substrates by plasma-assisted molecular beam epitaxy.The AIN crystalline quality is analysed by transmission electron microscope and x-ray diffraction(XRD)rocking curves in both(002)and(102)planes.The surface profiles of nucleation layer with different thicknesses after in-situ annealing are also analysed by atomic force microscope.A critical nucleation thickness for realising high quality AIN films is found.When the nucleation thickness is above a certain value,the(102)XRD full width at half maximum(FWHM)of AIN bulk increases with nucleation thickness increasing,whereas the(002)XRD FWHM shows an opposite trend.These phenomena can be attributed to the characteristics of nucleation islands and the evolution of crystal grains during AIN main layer growth.

Podem apresentar sinais e sintomas pouco específicos e estão associados a um substancial aumento na morbimortalidade dos pacientes internados em unidades de terapia intensiva. Os agentes antitrombóticos são o pilar no tratamento e prevenção do tromboembolismo. Esta classe é também utilizada na prevenção do acidente vascular encefálico, na fibrilação atrial, na prevenção de eventos embólicos da insuficiência cardíaca, em pacientes com próteses valvares e têm sido associados a antiplaquetários na prevenção secundária da síndrome coronária aguda. Agentes antitrombóticos, como aspirina, clopidogrel, antagonistas da vitamina K e foundaparinux (inibidor indireto do fator Xa já foram incorporados na prática clínica rotineira dos serviços de terapia intensiva. Recentemente, tem-se demonstrado grande interesse nos agentes que inibem seletivamente o fator Xa e a trombina. Estes apresentam estrutura molecular pequena e inibem simultaneamente o fator da coagulação livre no plasma e ligado ao trombo.

  7. Effects of the InAIN growth temperature and In mole fraction on subband transport in InxAI1-xN/(AIN)/GaN/AIN heterostructures

    International Nuclear Information System (INIS)

    Subband transport properties of the two-dimensional electron gas in InxAI1-xN/(AIN)/GaN/AIN heterostructures were investigated by means of variable magnetic-field Hall measurement between 30 K and 290 K. The experimental data was analyzed by using quantitative mobility spectrum analysis technique. The 2-dimensional electron gas with 1 or 2 subbands and the 2-dimensional hole were detected with i-quantitative mobility spectrum analysis technique. Mobility of the second subband of 2DEG was found to be higher than that of the first subband. The sheet carrier density for Hall, the first and the second subband were reduced while Indium mole fraction was increasing. This behavior is a result of total bound interface sheet density. During In mole fraction was increasing, second subband mobility was decreased.The first subband and Hall mobility was decreased once InAIN growth temperature was increased

En conclusión, los resultados obtenidos permitieron establecer que no existen diferencias para la obtención de PRP bovino, mediante el uso de CS o ACD-A como anticoagulantes. Los resultados sugieren la conservación de plaquetas homogéneas y estables estructuralmente en el PRP bovino, especialmente cuando se utilizó citrato de sodio.

    Full Text Available Chromium and its compounds give toxic and/or hazardous characteristics to all those industrial wastes, solids or liquids, that contain them. Organic solvent extraction is a technique that allows the recovery of chromium contained in these residues. In this work the extraction of Cr(III from aqueous solutions with solutions of a cationic reactive (DEHPA in kerosene is studied. In the same way the stripping process was studied. It has been found that Cr(III and DEHPA react in a 1/1 molar ratio, being the extraction kinetics very fast. Final aqueous phase final pH influence extraction yield, so that it is necessary to work with pH values between 3 and 4. It must be added a modifier (isodecanol to the organic phase to avoid the formation of a third phase in the stripping process. The concentration of isodecanol has to be higher than 15 %, so the organic phase used was a solution of 12.5 % v/v DEHPA in kerosene and 20 % v/v isodecanol. The stripping process is slow and must be carried out in an oxidant alkalyne medium, thus an aqueous solution of NaOH and H2O2 was used. An increase in the concentration of NaOH and H2O2 leads to an increase in the stripping yield initially, and becomes stable when concentrations of NaOH and H2O2 used are higher than 0.45 N and 4 % v/v respectively.

    El cromo y sus compuestos confieren un carácter tóxico y/o peligroso a los residuos industriales, sólidos o líquidos, que los contienen.

    2009-01-01

    Full Text Available Role and action selections are two major procedures of the game strategy for multiple robots playing the soccer game. In role-select procedure, a formation is planned for the soccer team, and a role is assigned to each individual robot. In action-select procedure, each robot executes an action provided by an action selection mechanism to fulfill its role playing. The role-select procedure was often designed efficiently by using the geometry approach. However, the action-select procedure developed based on geometry approach will become a very complex task. In this paper, a novel action-select algorithm for soccer robots is proposed by using the concepts of artificial immune network (AIN. This AIN-based action-select provides an efficient and robust algorithm for robot role selection. Meanwhile, a reinforcement learning mechanism is applied in the proposed algorithm to enhance the response of the adaptive immune system. Simulation and experiment are carried out to verify the proposed AIN-based algorithm, and the results show that the proposed algorithm provides an efficient and applicable algorithm for mobile robots to play soccer game.

    AIN/Al0.3Ga0.7N superlattices were grown on (0001) sapphire substrate by metal-organic chemical vapor deposition (MOCVD). The superlattice period varies from 6 to 30. The layer thickness of different period stack was designed. GaN or AiGaN template was employed for growing AIN/AIGaN superlattices. Re-flectivity, SEM, AFM and XRD data of the AlxGa1-xN/AIN superlattices are presented. It is found that the templates used have an intensive impact on surface roughness and interfacial properties of following AIN/AIGaN superlattices. The result of atomic force microscopy indicates that AIN/AIGaN superlattices grown on GaN template exhibit quasi-two-dimensional growth mode. The resulting superlattice has a smooth surface morphology and distinct interface. No crack is observed in the area of a 2-inch wafer.

    Full Text Available Owing to the construction of the new dam on the river Ain. the water of the river level has risen considerably above the earlier level of flow at the suspension bridge in the neighbourhood of Serrieres sur Ain. Hence it became necessary to substitute this structure by a more modern one, suitable to present day traffic demands. This paper summarises the main features of this new bridge. The new bridge spans the river by means of a reinforced concrete arch of 120 m span. The arch is circular, and the deck rests on a palissade supported by the arch. The maximum rise is 30 ms at the crown. The deck carries a roadway 7 ms wide and two sidewalks of 1 m width each, for pedestrians. The deck is supported by by four longitudinal beams, and the arch has a box section and 4 longitudinal stiffners. In the crown zone the stiffners, the deck and the cylindrical surfaces become integrated and enclose three hollow chambers. This structure has great stiffness. The depth of the arch is constant, except at the crown, and is 2.40 ms. This depth gives the arch a pleasing and slender aspect. The palissade consist of four rows of columns, of 0.80x0.20 ms section, at intervals of 12.50 ms. The radius of the arch is 78.80 ms, and its transversal box section has a total width of 8.60 ms. The thickness of the inner cylindrical surface is 0.20 ms. The springers consist of two large reinforced concrete blocks, of approximately 10 ms length and 4.70 ms height. The construction of the bridge was done with the aid of a Blondin cable, of 5 tns capacity, spanning 290 ms. The main constructional aid was a. wooden scaffolding, cantilevered from the sides, consisting of 10 trusses. The timber elements were nailed and bolted together. The top part of the framework supports a formwork, made with a double layer of boards, 27 mm in thickness, crossing each other at 45°. The scaffolding was erected in successive phases and a number of guy cables were employed to stabilise the structure

    Through air sampling, it was possible to evaluate microbial contamination in environments at high risk of infection, and to check the efficiency of ventilation system and the medical team's hygiene procedures. This study measured the concentration of particulate matter (PM) 2.5 or less microns and microbiological organisms in operating rooms (OR), intensive care units (ICU) and emergency rooms (ER) in Ain Shams University Surgery Hospital, and to assess ventilation characteristics in operating rooms in the hospital. The passive air sampling was done from ICUs, ORs, and ERs in Ain Shams University Surgery Hospital. Also for each operating room, an observational checklist was done to record other factors that may affect air quality in the room. The evaluated air quality indices were: suspended (PM) 2.5 micrometer or less, culture media and microbial identification of bacteria and fungi, and temperature and relative humidity. The results showed that the highest mean found for bacterial (105.70±30.49) and fungi concentration (7.50±5.30) was in ER. The three settings did not differ statistically as regard levels of PM 2.5, temperature, and relative humidity. A positive correlation exits between bacteria and fungi concentration on one hand and relative humidity on the other. Diphteroid, CONS, MRSA, S. aureus, and Anthracoid were the most frequent isolated bacterial types, while Penicillium and Asperigillus fumigatus were the most frequent isolated fungi. In operating rooms, the percent of unmasked persons present and the temperature positively influence the bacterial count, while ventilation condition is negatively influencing fungi count, and the number of persons present in the operating room positively affects the PM level.

Se apresenta sob as formas de filoquinona (K1-predominante, dihidrofiloquinona (dK, menaquinona (K2 e menadiona (K3. Os fatores que interferem em sua absorção são: má absorção gastrintestinal, secreção biliar, ingestão insuficiente e uso de anticoagulantes, entre outros. As principais fontes de vitamina K são os vegetais e óleos, sendo esses os responsáveis pelo aumento da absorção da filoquinona. Os alimentos folhosos verde escuro, os preparados à base de óleo, oleaginosas e frutas como o kiwi, abacate, uva, ameixa e figo contêm teores significantes de vitamina K, enquanto que os cereais, grãos, pães e laticínios possuem teores discretos. A ingestão diária de aproximadamente 1µg por quilo de peso é considerada a mais segura, inclusive para a utilização de anticoagulantes orais, em que a concentração estável da vitamina proporciona a eficácia no tratamento. A droga anticoagulante oral geralmente utilizada é a varfarina, administrada como profilática e para tratamento de fenômenos tromboembólicos. Essa intervenção medicamentosa é monitorada pelo tempo de protrombina expresso pela razão normalizada internacional, tendo como objetivo estabelecer a faixa terapêutica entre 2 e 3, minimizando o risco de hemorragias.

    White clays of Ain Khemouda (Western Tunisia), filling the post-Miocene palaeokarsts cavities dug in the intermediate limestones bed of the Douleb formation (Senonian system), were used as raw materials for the preparation of ceramic bodies. Natural clay samples, collected from the Ain Khemouda palaekarsts to the North of Jebel Semmama (Kasserine, Tunisia), were characterized by different techniques. Chemical and mineralogical analyses were carried out by atomic absorption spectroscopy (AAS) and X-ray diffraction (XRD), respectively. Thermal analysis was also performed by thermogravimetry (TG-DTA), dilatometry and Bigot's curve. Chemical analysis indicated that the studied clay was composed of silica and alumina as major elements with the ratio SiO2/(Al2O3 + Fe2O3) close to 2. Significant amounts of zinc and iron oxides subordinated the main alumino-silicates minerals. Mineralogical analysis showed that Ain Khemouda white clay consisted of halloysite and meta-halloysite mixture. Characteristic peaks of halloysite occurred near 10 Å and 7 Å. Transmission electron microscopy (TEM) images showed rolled wafers, characterizing the tubular shape of halloysite. From these results, it could be concluded that Ain Khemouda clay was Zn-aluminous hydrated halloysite (10 Å). In addition, cation exchange capacity (CEC) was relatively low (18 mEq/100 g), indicating insufficient edge valences. Industrial ceramic tests performed at the laboratory scale indicated that the Ain Khemouda clays have the required technical specifications to be used as raw materials for ceramic tiles and refractory ceramic manufacturing.

    Al-Ain is the second largest city in the Emirate of Abu Dhabi and the third in the UAE. Currently, desalination plants are the only source of drinking water in the city with an average daily supply of 170 MIG. Recently, Abu Dhabi Urban Planning Council (UPC) released Al-Ain 2030 Plan. Projects suggested in this plan, over and above the expected natural population growth, will certainly put additional stress on the water resources in the city. Therefore, Al-Ain city seems to be in urgent need for an integrated water resources management strategy towards achieving sustainable development. This strategy will contain three main components; namely, a Water Demand Forecasting Model (WDFM), a Water Budget Model (WBM), and a Water Resources Optimization Model (WROM). The main aim of this paper is to present the WBM that estimates all inflows and outflows to assess water resources sustainability in the city.

    Full Text Available La anticoagulación conseguida durante el tratamiento con anticoagulantes orales antagonistas de la vitamina K (AVK varía entre unos pacientes y otros debido a factores individuales y ambientales. La intensidad de la anticoagulación condiciona el riesgo hemorrágico. Por tanto, es probable que los pacientes especialmente sensibles a los AVK corran un riesgo hemorrágico mayor, especialmente durante las primeras semanas. En esta revisión se va a discutir el papel de una serie de polimorfismos de las enzimas involucradas en la metabolización de los AVK o en el ciclo de la vitamina K. Dos polimorfismos del citocromo P450 2C9 y uno de la enzima VKORC1 son responsables de un alto porcentaje de la variabilidad observada en la sensibilidad a los AVK. Aunque parece que dichas alteraciones genéticas se asocian con el riesgo de experimentar una hemorragia severa, confirmar este extremo requerirá estudios más amplios y mejor diseñados.The degree of anticoagulation obtained during oral anticoagulation therapy with vitamin K antagonists (VKA varies among patients due to individual and environmental factors. The rate of anticoagulation influences the hemorrhagic risk. Therefore, it is plausible that patients specially sensitive to oral anticoagulants are at higher hemorrhagicc risk, specially during the first weeks. The role of a series of polymorphisms of the enzymes involved in the metabolism of VKA or in the vitamin K cycle are reviewed. Three polymorphisms, two in the cytochrome P450 2C9 and one in the VKORC1 enzyme, are responsible for a high portion of the variability observed in the sensitivity to AVK. Although the available literature suggests that these genetic variants could increase the risk of severe hemorrhage, larger, well designed studies are needed to confirm this notion.

    Full Text Available Após cerca de 50 anos de experiência com a heparina e antagonistas da vitamina K (AVK, pesquisas e estudos com novos anticoagulantes vêm evoluindo de forma crescente nos últimos anos. Embora consagrados pelo uso, os anticoagulantes tradicionais têm limitações importantes em termos de controle laboratorial, complicações, efeitos colaterais, interações com medicamentos e dieta. A heparina não fracionada (HNF tem interação com proteínas plasmáticas e parede vascular, pode desencadear trombocitopenia induzida pela heparina (TIH, só pode ser administrada por via parenteral, exige controle laboratorial pelo teste da tromboplastina parcial ativada (TTPa, pode provocar osteoporose e alopecia quando usada por períodos prolongados e sua produção tem origem biológica. A AVK tem a vantagem de poder ser ministrada por via oral, mas o controle (feito pela razão normatizada internacional pode ser difícil em alguns casos, já que tem início de ação demorado, janela terapêutica estreita, interação com dieta e grande número de medicamentos, pode provocar necrose de pele em portadores de deficiência de antitrombina e de proteínas C e S, e pode induzir alterações fetais quando usada na gravidez. Na década de 1980, surgiram as heparinas de baixo peso molecular, que foram uma evolução da heparina não fracionada, pois apresentaram maior biodisponibilidade, dosagem por peso corporal, sem necessidade de controle laboratorial, administração por via subcutânea, menor risco de trombocitopenia induzida pela heparina, e eficácia e segurança similares à heparina não fracionada. Na última década surgiram, então, uma série de novos anticoagulantes no mercado, os quais têm apresentado resultados promissores em várias situações de profilaxia e tratamento do tromboembolismo venoso. Nesta revisão, são apresentados as novas heparinas de baixo peso molecular, as heparinas de ultrabaixo peso molecular, os pentassacarídeos, os

    Closing water balance is very crucial on laying effective Water Resources Management strategies. The goal of this study is to assess the potential of satellite imagery to close the water budget over the region of Al Ain city in the Emirate of Abu Dhabi, in the UAE. Water storage variation over the study area was determined from 2005 to 2014 by calculating the difference between inflows and outflows of the system. The outflow included evapotranspiration and discharged wastewater after treatment. The study area comprises Zakher Lake where the treated wastewater is discharged. A series of Landsat images were used to monitor the changes in the lake extent and infer total water volume using a high resolution (15m) digital elevation model. Evapotranspiration was estimated from NCEP reanalysis data over agriculture and green areas in the watershed delineated using Landsat images. The inflow included precipitation, desalinated water supply, and water reuse. Precipitation was obtained from Al Ain airport observations. Water supply from desalination plants and water reuse reported by local authorities were also used. Time series of GRACE observation over the study area were used to assess the inferred water storage variation. The inferred water storage and GRACE anomalies were in agreement as the obtained correlation coefficient was 0.53. Both time series showed a significant decreasing trend suggesting that water storage in the study area is being depleted.

    The urban growth of AL Ain city has been investigated using remote sensing data for three different dates, 1972, 1990 and 2000. We used three Landsat images together with socio-economic data in a post-classification analysis to map the spatial dynamics of land use/cover changes and identify the urbanization process in Al Ain resort city, United Arab Emirates. Land use/cover statistics, extracted from Landsat Multi-spectral Scanner (MSS). Thematic Mapper (TM) and Enhanced Thematic Mapper plus (ETM +) images for 1972. 1990 and 2000 respectively, revealed that the built-up area has expanded by about 170.53km2. The city was found to have a tendency for major expansion in four different directions: along the Abu Dhabi highway, along Dubai highway, Myziad direction and Hafeet recreational area. Expansion in any direction was found to be governed by the availability of road network, suitability for construction, utilities, economic activities, geographical constraints, and legal factors (boundary with Sultanate of Oman). The road network in particular has influenced the spatial patterns and structure of urban development, so that the expansion of the built-up areas has assumed an accretive as well as linear growth along the major roads. The research concludes that the development is based on conservation of agricultural areas (oases) and reclamation of the desert for farming and agricultural activities. The integration of remote sensing and GIS was found to be effective in monitoring LULC changes and providing valuable information necessary for planning and research.

    Full Text Available Abstract Background Reactive oxygen species (ROS are formed under natural physiological conditions and are thought to play an important role in many human diseases. A wide range of antioxidants are involved in cellular defense mechanisms against ROS, which can be generated in excess during stressful conditions, these include enzymes and non-enzymatic antioxidants. The aim of this study was to evaluate the antioxidant responses of mice to two diets control, commercial and the purified AIN 93 diet, commonly used in experiments with rodents. Results Malondialdehyde (MDA and hydrogen peroxide (H2O2 concentrations and superoxide dismutase (SOD and glutathione reductase (GR activities determined in the liver were lower in the group of mice fed with the AIN 93 diet, while catalase (CAT activity was higher in the same group, when compared to the group fed on the commercial diet. Liver glutathione peroxidase (GSH-Px activity was similar in the groups fed on either AIN 93 or the commercial diets. Two SOD isoforms, Mn-SODII and a Cu/Zn-SODV, were specifically reduced in the liver of the AIN 93 diet fed animals. Conclusions The clear differences in antioxidant responses observed in the livers of mice fed on the two diets suggest that the macro- and micro-nutrient components with antioxidant properties, including vitamin E, can promote changes in the activity of enzymes involved in the removal of the ROS generated by cell metabolism.

La dieta AIN-93 es ampliamente utilizada, pero hay algunos informes de esteatosis hepática en ratones Wistar alimentadas con esta dieta. Objetivo: Evaluar las repercusiones hepáticas de la ingesta de la dieta estándar AIN-93 en ratones Wistar. Métodos: Cuarenta recién destetados, ratones Wistar machos, con 21 días de edad fueron alimentados con la dieta AIN-93 o una dieta comercial, durante 1 mes o 4 meses. El aumento de peso, la bioquímica sérica, la histología hepática y el perfil de ácidos grasos hepáticos fueron analizados. Resultados: Se observó esteatosis hepática, especialmente en el grupo alimentado con la dieta AIN-93. Glucosa en suero, peso absoluto y relativo del hígado y los niveles hepáticos de ácidos grasos oleico, palmitoleico, esteárico y palmítico se relacionaron con la esteatosis observada, mientras el lipidograma y los marcadores sanguíneos de la función hepática, no se relacionaron. Conclusión: La dieta estándar AIN-93 causó esteatosis hepática aguda en ratones Wistar, que puede comprometer su uso como una dieta estándar para los estudios experimentales con roedores. El perfil de ácidos grasos hepáticos se asoció con la esteatosis, con posibles implicaciones para el pronóstico de la enfermedad.

Questionnaires were filled through personal interviews with 660 pregnant women. Of the respondents, 62.4% had heard of folic acid and 39.2% knew about the role of folic acid supplementation in prevention of congenital anomalies. Knowledge about using folic acid before and in the first trimester of pregnancy was highest among university-educated women and those working in professional occupations. Only 18.8% of women reported taking folic acid, and 8.8% had used it before conception. Awareness campaigns are suggested to improve knowledge about folic acid among women in the childbearing period in Egypt.

    The aim of this study was to establish the carrier rate of group A beta haemolytic streptococci in school children in Al Ain, United Arab Emirates. One thousand and two randomly selected school children aged 5-7 years had their throats swabbed twice for both culture and direct antigen detection of group A streptococci. One hundred and fourteen children (11.3%) had both a positive antigen and culture test, while 216 (21.6%) had antigen-positive tests only and 16 (1.5%) had a positive culture only. Thus, the combination of culture and antigen detection revealed a carrier rate of 35.4% in the children examined. We conclude that in an affluent but isolated desert area on the Tropic of Cancer, group A streptococcal carriage rate is high. Antigen detection is superior to culture techniques in asymptomatic carrier studies.

Os GAGs foram extraídos com papaína em tampão acetato de sódio 100 mM (pH 5,0 contendo cisteína e EDTA (5 mM, seguido por cromatografia de troca iônica em coluna de DEAE-celulose, utilizando um gradiente de NaCl. As frações obtidas foram liofilizadas e submetidas à eletroforese em gel de agarose a 0,5%. A atividade anticoagulante foi avaliada por meio do tempo de tromboplastina parcial ativada (TTPA, usando-se plasma humano normal e HEP padrão (193 UI mg-1. O perfil cromatográfico mostrou a separação de duas diferentes frações de GAGs (F I e F II, eluídas com 0,50 e 0,75 M de NaCl, respectivamente, revelando, por eletroforese, frações distintas em densidade de cargas, porém ambas mostrando GAGs com mobilidades semelhantes ao dermatam sulfato (DS padrão, sugerindo-se a identificação preliminar desse GAG. Os GAGs modificaram o TTPA, cujas atividades perfizeram, respectivamente, 4,72 (F I e 23,80 (F II UI mg-1, e expressaram-se dose-dependente. Portanto, o DS anticoagulante da pele de O. niloticus sugere uma fonte interessante para estudos posteriores de atividade antitrombótica.

    Full Text Available AIM: To study the mechanism of road traffic collisions (RTC, use of safety devices, and outcome of hospitalized pediatric and youth RTC injured patients so as to give recommendations regarding prevention of pediatric RTC injuries. METHODS: All RTC injured children and youth (0-19-year-olds who were admitted to Al Ain City's two major trauma centers or who died after arrival to these centers were prospectively studied from April 2006 to October 2007. Demography of patients, road-user and vehicle types, crash mechanism, usage of safety devices, injured body regions, injury severity, Revised Trauma Score, Glasgow Coma Scale, intensive care unit admissions, hospital stay and mortality were analyzed. RESULTS: 245 patients were studied, 69% were vehicle occupants, 15% pedestrians, 9% motorcyclists and 5% bicyclists. 79% were males and 67% UAE citizens. The most common mechanism of RTC was rollover of vehicle (37% followed by front impact collision (32%. 32 (13% of vehicle occupants were ejected from car. 63% of ejected occupants and 70% of motorcyclists sustained head injuries. Only 2% (3/170 vehicle passengers used seatbelts and 13% (3/23 motorcyclists a helmet. CONCLUSIONS: Male drivers and UAE nationals were at high risk of RTC as drivers and as motorcyclists. Ejection rate was high because safety restraint use was extremely low in our community. More education and law enforcement focusing especially on car/booster seat use is needed.

  5. Sorption behavior of cesium on Ain Oussera soil under different physicochemical conditions

    International Nuclear Information System (INIS)

    In the present study, the sorption behavior of cesium was investigated in Ain Oussera soil around the Es-Salam reactor facility. This study was conducted using batch method under different physicochemical conditions including contact time, ionic strength, pH, solid/liquid ratio and temperature. The results showed that sorption followed pseudo-second-order kinetics with a good regression coefficients (R2 = 0.999). The activation energies were 11.26 and 15.21 kJ mol-1 which correspond to ion-exchange-type sorption mechanism. The adsorption was favored at low temperature and it was exothermic (ΔH0 -1) and spontaneous (ΔG0 -1 at 23 deg. C and -13.2 kJ mol-1 at 60 deg. C). The presence of competing cations such as K+ and Ca2+ ions in groundwater can significantly reduce the Cs adsorption onto soil. Desorption reaction was also investigated using three reagents with different ionic strengths (deionized water, groundwater and 0.1 M KCl solution). The results showed that Cs ions were preferentially distributed onto high affinity sorption sites.

    Full Text Available Water from boreholes in Arib (Ain Defla, south-west of Algeria was investigated to ascertain its quality status and suitability for drinking and domestic uses. Fifty six water samples were collected from four boreholes. The analyses of the Coliform counts obtained from various boreholes samples ranged between 0 and 200 CFU/ 100 ml with regard to total Coliforms and between 0 and 8 CFU/ 100 ml with regard to fecal Coliforms. Three of the boreholes samples showed contamination by Streptococcus sp. Pathogens like Salmonella were not identified but some low levels of sulfite-reducing bacteria was found. The interviews were done to assess perceptions on water taste problems, odour, colour, and turbidity and health problems. The respondents were taken from people in the community using random sampling technique. Sixty people were sampled at each area surrounding the boreholes. It was found out that 43.3% of the respondents rated their drinking water safe for consumption as well as absence of illness after drinking as indicators for judging the quality of the water. The others respondents (56.7% reported having at least some concerns with safety of their water.  More  than 20% of the households reported at least one household member having suffered some water related illness in the past two years. Respondents were asked to judge the quality of the water, based on four sensory characteristics of drinking water. Many respondents rated the smell (33.3%, taste (20%, colour (23.3% and turbidity (23.3%. These results showed that all the samples did not satisfy the WHO requirements for bacteriological characteristics in human consumption.

    The aim of this paper is to illustrate with a lot of data series on the Ain river, the changes observed on water temperatures, especially for summer values. Models are calibrated and used to simulate water temperatures under different assumptions of flow management to deduct effects of dams. Projections on the period 1950-2099 were made on the basis of a climate scenario, a hydrological model and models of water temperature. This simulation confirms the risk of a sharp rise in water temperatures in summer related to rising air temperatures and lower low flows. (authors)

    Full Text Available The reportedly low standard quality of heparin (HEP for use in cardiac surgeries has led to concern in the Brazilian and international markets. Sulfated polysaccharides (SPs from seaweeds have been regarded as promising substitutes for HEP. The aim of this study was to sequentially extract total SPs (TSPs from Caulerpa cupressoides (Chlorophyceae with papain in 100 mM sodium acetate buffer (pH 5.0 containing 5 mM cysteine and 5 mM EDTA, followed byfractionation by ion-exchange chromatography (DEAE-cellulose, and then evaluate the anticoagulant potential of SP fractions by activated partial thromboplastin time (APTT using normal human plasma and compare it to standard HEP (193 IU mg-1. The obtained fractions were chemically characterized by chemical composition and agarose gel electrophoresis. The yield was 4.61%, and three fractions of SP (F I, F II and F III eluted with 0.50, 0.75 and 1.00 M of NaCl,respectively, were observed on chromatography profiles; however, differences in charge densities patterns and degree of resolution among them were revealed by electrophoresis. SPs were capable of modifying APTT only in fractions eluted with 0.75 M of NaCl, whose activities were 23.37 and 25.76 IU mg-1, respectively, and the charge density was prerequisite to activity. Therefore, C. cupressoides is a source of SPs possessing low anticoagulant potential compared to HEP.O baixo padrão de qualidade outrora declarado da heparina (HEP para o uso em cirurgias cardíacas tem levado preocupação nos mercados nacional e internacional.

    Los antiinflamatorios no esteroideos (AINES son un grupo heterogéneo de compuestos con actividad analgésica, antipirética y antiinflamatoria que comparten efectos secundarios indeseables, tales como: ulceración gástrica e intestinal, anemia, bloqueo de la agregación plaquetaria, inhibición de la motilidad uterina e hipersensibilidad. Los AINES se utilizan por vía tópica con el fin de aliviar lesiones en tejidos blandos a los cuales puede llegarse directamente a través de la piel, evitando así los efectos colaterales indeseables.

    Actualmente para la gran mayoría de los medicamentos se exige valorar la Biodisponibilidad como criterio de calidad. Biodisponibilidad se define como la cantidad de fármaco que llega a sangre o plasma después de la administración del medicamento que lo contiene y la velocidad a la cual este proceso ocurre; esta determinación de Biodisponibilidad no resulta útil en el caso de medicamentos que se administran a través de la piel y no alcanzan circulación sistémica; la biodisponibilidad relativa o Bioequivalencia es la comparación de las biodisponibilidades de dos medicamentos para determinar si son similares en su comportamiento farmacocinético dentro del organismo.

    El presente trabajo pretende estandarizar y validar un método que permita determinar concentraciones de fármaco en tejidos, en este tipo de medicamentos administrados por vía tópica, que no alcanzan circulación sistémica y por lo tanto no pueden ser cuantificados en sangre o plasma; además pretendemos que esta metodología pueda ser propuesta como una técnica para determinar biodisponibilidad y/o bioequivalencia para este tipo de productos. Para lograr estos objetivos, inicialmente, se induce la inflamación a un grupo

En el presente trabajo se investiga la capacidad hemostática de la cola de fibrina como presidio hemostático en los pacientes bajo terapia anticoagulante, exponiendo los resultados de la experimentación sobre la base de un Standard de referencia del trauma quirúrgico y de la intensidad de la terapia anticoagulante. Materiales y métodos: Han sido seleccionados 20 pacientes en terapia anticoagulante con una edad comprendida entre los 44 y 79 años, se han realizado, según las modalidades apropiadas, simples exodoncias o más complejas de dientes mono-, bi- y tri-radiculares. Tras la alveoloplastia se ha colocado una esponja de fibrina reabsorbible en forma de gel (Gingistat® y se ha realizado la sutura. El trauma quirúrgico ha sido clasificado por medio de una escala cuantitativa que puede expresar de forma unívoca el grado de trauma. La categoría de trauma por cada paciente se establece por la suma de los valores obtenidos de cada uno de los procedimientos unitarios. Ha sido posible evaluar el coeficiente de relación entre la intensidad del efecto anticoagulante (medido por medio del lNR y número de complicaciones hemorrágicas que se han verificado, además de entre el grado de trauma quirúrgico y el número de complicaciones que se han presentado. Resultados y Conclusiones: Se demuestra que el utilizo terapéutico de la cola de fibrina puede ser considerado como un válido soporte por la optimización de la hemostasis en los pacientes con alteraciones de la coagulación inducidas farmacológica menteAim of the work: The authors emphasize how an effective emostatic method is extremely important in patients treated with anticoagulating therapy

    Amorphous In-Ga-Zn-O is an important oxide semiconductor in advanced display technologies. Despite its importance, little has been reported on the thermal and elastic properties of this material. Here, the temperature dependence of the thermal conductivity, shear modulus, and internal friction of a-InGaZnO4 and a-In2Ga2ZnO7 films are presented. The thermal conductivity of a-In2Ga2ZnO7, measured from 100 K to room temperature, was found to be larger than that of a-InGaZnO4 over the entire temperature range. At room temperature the thermal conductivities were 1.9 W/m K and 1.4 W/m K for the a-In2Ga2ZnO7 and a-InGaZnO4 films, respectively. The shear modulus and internal friction of these films were measured in the temperature range of 340 mK to 65 K. At 4.2 K the shear modulus of the a-InGaZnO4 and a-In2 Ga2ZnO7 films was 44 GPa and 42 GPa, respectively. The internal friction of thin films at each composition exhibited a temperature dependence and magnitude that is in agreement with that observed in all amorphous solids. As the self-heating effect is of concern in the development of amorphous In-Ga-Zn-O based thin film transistors on low thermal conductivity substrates, a thermal model of such a device utilizing a-In2Ga2ZnO7 or a-InGaZnO4 as the active layer was explored. It was found that the temperature increase of the thin film transistor channel is essentially independent of the thermal conductivity of the active layer.

  6. The role of oxbow lakes in the off-channel storage of bed material along the Ain River, France

    Incidents of chute cutoff redistribute floodplain sediment into rivers, causing downstream bar growth while simultaneously creating accommodation space for the storage of sediment within the floodplain in the form of oxbow lakes. Oxbows may be able to sequester enough sediment to balance the amount produced by chute incision, but the long-term consequences of chute cutoff on reach-scale sediment budgets have so far remained unclear. This has been due to a relative paucity of field observations that quantify the exchange of coarse sediment between the channel and floodplain. Here, we take advantage of a unique opportunity to document the sediment budget of a reach of the Ain River, France, that has experienced three recent incidents of chute cutoff. Monitoring of the river prior to chute incision allowed us to precisely quantify the rates of bed-material transfer over a thirteen-year period using a combination of bathymetric surveys, LiDAR data, and aerial photographs. The abandoned channels under study sequestered between 17 and 40% of the sediment introduced to the channel, with most of the rest of the sediment being stored within the river itself. Aggradation of the abandoned channels was not evenly distributed, instead occurring by the growth of point bars and thus implying that the abandoned channel planform may be an important control on aggradation rates. Our results make clear that although oxbows may provide a significant sink for bed material, the amount of sediment sequestered within them cannot compensate for the loading caused by chute incision.

The microscopic structure of the film was characterized by small angle scat tering (SAXS) and scanning electron microscope (SEM) . The effects of nano-AIN content on the volume resistivity, permittivity(e) and dielectric loss of the film were studied. The results show that with increasing the nano-AIN content, the fractal structure changes from quality fractal to surface fractal. The permittivity of the film attains the minimum value when the nano-AIN content is 1%. The volume resistivity is increased by one order of magnitude, and the dielectric loss in creases obviously in low frequency range, which indicates that the addition of A1N can improve the insulation performance.

  10. The impact of weathering on the uranium-bearing phosphates of Ain Laylon in the Syrian coast, using radon and gamma ray surveys

    International Nuclear Information System (INIS)

    A combination of several exploration techniques was carried out at the main phosphatic outcrop of Ain Laylon in the Syrian coastal region. The survey was extended along an E-W profile parallel to Wadi Al-Mzeraa over a distance of about 23 km from Ain Laylon site towards the shoreline of the Mediterranean Sea. The techniques used in this survey included soil radon emanometry, gamma ray spectrometry and soil geochemistry, with the purpose of evaluating the effects of weathering and erosion on the uranium-hearing phosphate formations in the study ares. Soil radon concentration and gamma ray total count rates found to be ranging between 115-472 pCi/l and 52-520 cps over the main phosphate deposit of Ain Layton and between 16-241 pCi/l and 15-300 cps along the profile of Wadi Al-Mzeraa - Rwemiyeh respectively. Some suitable elements such as U, Zn, Pb, Cr, Fe and Sr were also analyzed to trace the dispersion pattern of uranium and its controls throughout the area. The results showed that the distribution of both radon emission and gamma ray activity, in accordance with chemical uranium and some associated trace elements, were almost identical over the study area. The anomalously high values in all cases were basically found to be related to the main phosphatic outcrop and to the reprecipitation processes at their vicinity following the alteration of the phosphates. The prevailing topographic conditions of the drainage system has probably played a crucial role in carrying the uraniferous solutions from its phosphatic source down to the nearby sedimentary environment. This appears to be sufficient enough to produce an anomalous halo resulting in the detection of some relatively high radon and gamma values of about 7 and 15 times the background respectively, especially close to the main phosphate outcrop. A notable gradual decrease was then observed at the following sampling sites along the pathway west of Ain Laylon site approaching the background level at a distance of

    This study aims to assess the impact of water harvesting constructed hydraulic structures (big and small dams, terraces, seuils for recharge…) on the evolution of piezometric head of Ain El Beidha groundwater table. The measurements of depth of water table, taken at the end of rain season and at the end of irrigation season, in many piezometers and monitoring wells, for a long period of observation before and after implementation of all the hydraulic structures, were used with the cumulative rain to the highest water table to diagnostic the effect of natural recharge and constructed hydraulic structures. According to the analysis of curves illustrating the evolution of piezometric head and rainfall over time, it was shown that despite the fact that the same amount of rain fall on the total area in the limits of Ain El Beidha groundwater table, the piezometers respond differently. This is because there are many sources of recharge and many factors affecting the recharge. First of all, the aquifer is divided in four compartments (the calcareous formation of Djebel El Houyareb, the plio-quaternary formation, the Miocene formation: Baglia and Saouaf). All those respond differently to the recharge by their capacity of infiltration and their hydrodynamic characteristics. The recharge of the groundwater table was increased by the implementation of small soil and water conservation structures, artificial lakes, El Haouareb Dam, run off in the natural Oued bads and seuils for recharge installed in the bads of oueds. The different piezometric drown maps were used to determine the flow direction and hydraulic gradient in order to identify the recharge areas, while tracking maps for three equal piezometric heads 210 m 300 m and 370 m established over different years made it possible to assess the impact of hydraulic structures, namely the effect of SWC and Ben Zitoun Lake. To illustrate the impact of El Houareb dam on the groundwater, the piezometric maps and local values

    AIN films with preferred c-axis orientation are deposited on Si substrates using the radio frequency (RF) magnetron sputtering method. The post-processing is carried out under the cooling conditions including high vacuum, low vacuum under deposition gas ambient and low vacuum under dynamic N2 ambient. Structures and morphologies of the films are analyzed by X-ray diffraction (XRD) and atomic force microscopy (AFM). The hardness and Young's modulus are investigated by the nanoindenter. The experimental results indicate that the (100) and (110) peak intensities decrease in the XRD spectra and the root-mean-square of roughness (Rrms) of the film decreases gradually with the increase of the cooling rate. The maximum values of the hardness and Young's modulus are obtained by cooling in low vacuum under deposition gas ambient. The reason for orientation variation of the films is explained from the perspective of the Al-N bond formation.

The results show that in the Zn, O codoped method, the introduction of active donator, atom O, causes acceptor energy level to shift toward low energy, thereby forming the energy levels of shallow acceptor. At the same time, the energy band widens and nonlocal characteristics become significant, thereby increasing the doping concentration of Zn atoms and the stability of the system. Zn, O codoping is more conducible to obtaining the p-type AIN.

    Full Text Available El Ain El Sukhna area was selected in the last ten years to initiate many governmental and investmental programs. The different activities in that area depend mainly on the groundwater of the Quaternary aquifer, which forms the main water bearing strata. In the present work, twenty one geoelctrical soundings using the Schlumberger configuration are carried out at selected sites especially in missing parts from wells to delineate the groundwater setting in such sites. Eight of them are conducted in the close vicinity of water wells, where lithologs and pumping test data of these wells are available to relate hydrologic and geoelctric measurements. The pumping tests data are analyzed by using AQTESOLV program and the geolectrical sounding data were interpreted by partial curve matching technique to obtain the initial parameters. The results indicated that, the transmissivity is found to be closely related with transverse resistance and the hydraulic conductivity with average transverse resistivity, while the salinity is inversely related with resistivity. Finally, priority map for drilling water wells is constructed to make the results more illustrative and useful for decision maker. The promising area for drilling is located at the western portion of the study region.

    The influence of applied electric fields on the absorption coefficient and subband distances in asymmetrical AlN/GaN coupled double quantum wells (CDQWs) has been investigated by solving Schrodinger and Poisson equations self-consistently. It is found that the absorption coefficient of the intersubband transition (ISBT) between the ground state and the third excited state (1odd -2even) can be equal to zero when the electric fields are applied in asymmetrical A1N/GaN CDQWs,which is related to applied electric fields induced symmetry recovery of these states. Meanwhile,the energy distances between 1odd -2even and 1even - 2even subbands have different relationships from each other with the increase of applied electric fields due to the different polarization-induced potential drops between the lett and the right wells. The results indicate that an electrical-optical modulator operated within the opto-communication wavelength range can be realized in spite of the strong polarization-induced electric fields in asymmetrical AIN/GaN CDQWs.

    TiN and TiAIN coatings are often used in fine blanking dies. The phase variation of TiN and TiAIN coatings was analyzed by XRD in this research. The residual stress of TiN coating and substrate and TiAIN substrate was measured using sin2i|* method, and the microhardness of the coating was measured by microhardness tester. The results show that: there is obvious preferred orientation in the crystal surface of TiN coating (111) and (222), the residual stress of TiN coating ranges from -2 347 Mpa to-1920 Mpa, and that of the substrate from-154.9 Mpa to-69.21 Mpa, both of which decrease with the increase of coating thickness. The main phase composition of TiAIN coating is Ti3Al3N2 and there is preferred orientation in the crystal surface of (107). The residual stress of the substrate is between -123.7 Mpa to 469.5 Mpa, mainly in tensile stress state, which has a large influence on the die life and increases along with the coating thickness. The microhardness of TiN and TiAIN coatings also increases along with the film thickness.%TiN和TiAlN涂层常应用于精冲模,采用XRD技术分析了不同厚度TiN和TiAlN涂层的相变化,并采用Sin2Ψ法测量了TiN涂层和基体以及TiAlN基体的残留应力,应用显微硬度计测量了涂层的显微硬度.结果表明:TiN涂层(111)和(222)晶面存在明显择优取向,涂层残留应力分布在-2 347 ~ -1920MPa,基体残留应力分布在-154.9~-69.21 MPa,均随厚度增加而减小;TiAIN涂层主要相成分为Ti3Al3N2,且(107)晶面存在择优取向,基体残留应力分布在-123.7 ~ 469.5 MPa,主要呈拉应力状态,且随厚度增加而增大,对模具寿命有较大影响;TiN和TiAIN涂层显微硬度随厚度增加而增大.

    human settlements and occupation, it is possible to characterize a threefold transition: first, the former transition between the pre-Islamic prehistoric societies and the development of Muslim societies; second, the more recent transition between the traditional historical society (farmers) and the contemporary society, characterized by the growth of urbanization, the creation of modern transport infrastructure and the concomitant growth of tourist flows; third, the current transition between the yesterday and tomorrow Al Ain City, due to the transformation of a local town centred on national economics all along the second half of the twentieth century, into an international town more open to the wider world with the management of a possible increased 20 % of tourist flow because of the inscription of Cultural Sites of Al Ain on the UNESCO's World Heritage List. It is not possible to completely ignore the fact that the Jebel Hafit and its foothills are partly crossed by an international boundary. In case of political tensions, this may cause some difficulties for the management of this territory, with contradictory requirements between security, tourism, traditional land use, and scientific research.

    Les feldspaths sont répandus dans l'écorce terrestre mais seuls les feldspaths potassiques et sodiques sont très recherchés dans l'industrie céramique et verrière. Pour qu'ils soient utilisables, ces matériaux doivent contenir très peu d'impuretés nocives de fer et surtout de silice. La carrière d'Ain-Barbar exploite la matière feldspathique de teneurs moyennes respectives 74,5% SiO{2}, 9,5% 12,75% Al{2}O{3}, 1,30% Fe{2}O{3} et 9,5 K{2}O (0,90% Na{2}O). Toutefois, on constate un taux très élevé en quartz ce qui diminue la valeur du produit marchand et une teneur élevée en fer ce qui donne au produit fabriqué, des aspects de coloration le rendant impropre à la commercialisation. A cet effet, une caractérisation minéralogique et chimique a été réalisée sur une série d'échantillons prélevés du site d'extraction de la substance utile. Des essais de préconcentration granulométrique ont montré qu'un classement dimensionnel peut offrir une qualité de produits acceptables par les céramistes.

    Full Text Available This article positions the translations of French verse works (plays and selected collections of individual poets that August Sang, Jaan Kross and Ain Kaalep made in the 1960s, onto the background of their own original works. At that time, August Sang translated four plays by Molière (The Misanthrope, Tartuffe, The School for Wives in 1961; Amphitryon in 1961, which have already been discussed in relation to the tradition of translating the French syllabic verse into Estonian, because these translations form a considerable part of the body of Estonian translations of French verse poetry. For Jaan Kross and Ain Kaalep, the wider context is created by the so-called free verse battles in the 1950s, to which we can link Kross’ translation of a selected collection of Éluard (Veel enne kostma peab, 1969 and Kaalep’s translation of a selected collection of Prévert (Kuidas portreteerida lindu, 1965. One of the two remaining translations by Kross, (Rostand’s Cyrano de Bergerac, 1964, can also be examined in relation to the problems of translating verse, but the other, (Béranger’s Laulud, 1963, should be discussed in the framework of intellectual and cultural resistance, a part of which was also the struggle put up for the existence of free verse in the 1950s and 1960s.Of August Sang’s original work, the article examines his collection of poems Võileib suudlusega (1963, written simultaneously with his translations of Molière’s plays and published right after them. Both the translations and the collection of original poems have attracted critics’ attention with their remarkable lack of linguistic constraint and simplicity. Although Sang has rarely voiced theoretical ideas about translation or explained his method, both his poetic image, outlined in the collection Võileib suudlusega, and his search for right words, reflected in the drafts of his translations, let us believe that the simplicity of expression and the avoidance of marked

Moreover, an environmental temperature sensor is integrated at the same time. The 2D micro structure wind velocity and direction sensor is prepared on an AIN substrate with thickness of 0.2 mm using the photolithography lift-off processing and laser micro processing technologies. The sensor is composed of a middle heater,four temperature detectors and a temperature sensor. In the four temperature detectors,8 thermal isolation holes are prepared using micro laser processing technique to reduce the heat conduction loss and enhance the effective exchange of thermal flow. The ANSYS simulation and performance test results on the proposed sensor verify the rationality of the design and the feasibility of the processing. A-nalysis results demonstrate that adopting thermal isolation holes can effectively improve the sensitivity of the four

RESULTADOS: Não houve diferença entre os tratamentos (chi²=2,352, p=0,671 para 61 pacientes com RNI inicial 8. Cinco dos 7 pacientes do grupo B que continuaram com superdosagem tinham RNI PURPOSE: To evaluate the response of 73 patients with antivitamin K (AVK overdose to 3 different therapeutic regimens. METHODS: Seventy three patients were evaluated in 94 occasions: group A (N=32, consisted of drug withdrawal for 2 days followed by reduced dosage; group B (N=37, drug withdrawal and reassessment within 4 days; group C (N=25, oral administration of vitamin K. Therapeutic range was set between INR-values of 2 and 4. RESULTS: Reversal regimens did not result in differences among 61 patients who had initial INR 4, but 5 of them were bellow 4.5, without increased bleeding risk. There were 10 patients in group C bellow therapeutic range, 6 of them with INR < 1.6, with risk of thromboembolism. Thirteen patients bled, but none required transfusion. CONCLUSION: Reversal of excessive oral anticoagulation can be safely performed by initial withdrawal of the drug, followed by lower doses. Vitamin K administration may lead to INR bellow the therapeutic range. This should be reserved for patients with high INR or in the presence of bleeding.

    Full Text Available I-WARP is based upon a nonhomogeneous Poisson approach to model breakage rates in individual water mains. The structural deterioration of water mains and their subsequent failure are affected by many factors, both static (e.g., pipe material, pipe size, age (vintage, soil type and dynamic (e.g., climate, cathodic protection, pressure zone changes. I-WARP allows for the consideration of both static and dynamic factors in the statistical analysis of historical breakage patterns. This paper describes the mathematical approach and demonstrates its application with the help of a case study. The research project within which I-WARP was developed, was jointly funded by the National Research Council of Canada (NRC, and the Water Research foundation (formerly known as the American Water Works Association Research Foundation – AwwaRF and supported by water utilities from USA and Canada.

    2015-01-01

    Bell's theorem is 50 years old. Still there is a controversy about its implications. Much of it has its roots in confusion regarding the premises from which the theorem can be derived. Some claim that a derivation of Bell's inequalities requires just locality assumption, and nothing more. Violations of the inequalities are then interpreted as ``nonlocality'' or ``quantum nonlocality''. We show that such claims are unfounded and that every derivation of Bell's inequalities requires a premise -- in addition to locality and freedom of choice -- which is either assumed tacitly, or unconsciously, or is embedded in a single compound condition (like Bell's ``local causality''). The premise is equivalent to the assumption of existence of additional variables which do not appear in the quantum formalism (in form of determinism, or joint probability for outcomes of all conceivable measurements, or ``additional causes`'', or ``hidden variables'', ``complete description of the state'' or counterfactual definiteness, etc....

    Full Text Available Background Peptic ulcer etiology has been changing because of H. pylori decline. Objectives To estimate peptic ulcer prevalence in 10 years-interval and compare the association with H. pylori and use of non-steroidal anti-inflammatory drugs. Methods Records assessment in two periods: A (1997-2000 and B (2007-2010, searching for peptic ulcer, H. pylori infection and non-steroidal anti-inflammatory drugs use. Results Peptic ulcer occurred in 30.35% in A and in 20.19% in B. H. pylori infection occurred in 73.3% cases in A and in 46.4% in B. Non-steroidal anti-inflammatory drugs use was 3.5% in A and 13.3% in B. Neither condition occurred in 10.4% and 20.5% in A and B respectively. Comparing both periods, we observed reduction of peptic ulcer associated to H. pylori (P=0.000, increase of peptic ulcer related to non-steroidal anti-inflammatory drugs (P=0.000 and idiopathic peptic ulcer (P=0.002. The concurrent association of H. pylori and non-steroidal anti-inflammatory drugs was also higher in B (P=0.002. Rates of gastric ulcer were higher and duodenal ulcer lower in the second period. Conclusions After 10 years, the prevalence of peptic ulcer decreased, as well as ulcers related to H. pylori whereas ulcers associated to non-steroidal anti-inflammatory drugs increased. There was an inversion in the pattern of gastric and duodenal ulcer and a rise of idiopathic peptic ulcer.

    Full Text Available The use of Primene 81R as extraction agent of chromium present in solid wastes containing nickel, iron and copper has been studied. The waste was leached with a sulphuric acid solution up to pH 3 and oxidation of Cr(III to Cr(VI with Caro acid was also studied. Because of the negative result of oxidation, the treatment was applied on Cr(III directly. Extraction/scrubbing/stripping process was studied in the leach. The composition of organic phase used in the extraction step was 10 % v/v Primene 81R, 10 % isodecanol and kerosene. All the iron, 91 % Cr, 10 % Ni and large part of the copper contained in the initial leach solution are recovered in the organic phase. In the scrubbing stage (with a sulphuric acid solution at pH 1,4, all the copper and nickel and 30 % Cr go to the washing liquor, while all the iron and 70 % Cr remained in the organic phase. In the stripping stage (with a 2N NH4OH or 2N NaOH solution all the iron and chromium are recovered as a precipitate of highly absorbent hydroxides. After the treatment mentioned, 63 % Cr and 100 % Fe are recovered as a mixture of hydroxides, and 28 % of the initial chromium, all the nickel and the copper are found in the washing liquor.

    Se estudia la aplicación del Primene 81R como agente de extracción del cromo presente en residuos sólidos que poseen níquel, hierro y cobre. El residuo se lixivió con disolución de ácido sulfúrico hasta pH 3 y se investigó la oxidación del Cr(III a Cr(VI con ácido de Caro. Ante el nulo resultado en la oxidación, se actuó directamente sobre el Cr(III. Se estudió el proceso de extracción/lavado/reextracción sobre la lejía de lixiviación. La fase orgánica empleada en la extracción estaba constituida por 10 % v/v de Primene 81R, 10 % de isodecanol y queroseno. En la fase orgánica se recupera todo el hierro, el 91 % Cr, el 10 % Ni y gran parte del cobre contenidos en la lejía de partida. En la etapa de lavado (con disolución de ácido sulfúrico de pH 1,4, todo el cobre y el níquel y el 30 % Cr pasan a las aguas de lavado, quedando en la fase orgánica todo el hierro y el 70 % Cr. En la reextracción (con NH4OH 2 N o con NaOH 2 N se recupera todo el hierro y el cromo como un precipitado de hidróxidos altamente absorbente. Después del tratamiento indicado se consigue recuperar el 63 % Cr y el 100 % Fe como una mezcla de hidróxidos, y en el agua de lavado se encuentra el 28 % Cr inicial, así como todo el níquel y el cobre.

    Full Text Available Abstract Background The cost effective provision of quality care for chronic diseases is a major challenge for health care systems. We describe a project to improve the care of patients with the highly prevalent disorders of diabetes and hypertension, conducted in one of the major cities of the United Arab Emirates. Settings and Methods The project, using the principles of quality assurance cycles, was conducted in 4 stages. The assessment stage consisted of a community survey and an audit of the health care system, with particular emphasis on chronic disease care. The information gleaned from this stage provided feedback to the staff of participating health centers. In the second stage, deficiencies in health care were identified and interventions were developed for improvements, including topics for continuing professional development. In the third stage, these strategies were piloted in a single health centre for one year and the outcomes evaluated. In the still ongoing fourth stage, the project was rolled out to all the health centers in the area, with continuing evaluation. The intervention consisted of changes to establish a structured care model based on the predicted needs of this group of patients utilizing dedicated chronic disease clinics inside the existing primary health care system. These clinics incorporated decision-making tools, including evidence-based guidelines, patient education and ongoing professional education. Results The intervention was successfully implemented in all the health centers. The health care quality indicators that showed the greatest improvement were the documentation of patient history (e.g. smoking status and physical activity; improvement in recording physical signs (e.g. body mass index (BMI; and an improvement in the requesting of appropriate investigations, such as HbA1c and microalbuminurea. There was also improvement in those parameters reflecting outcomes of care, which included HbA1c, blood pressure and lipid profiles. Indicators related to lifestyle changes, such as smoking cessation and BMI, failed to improve. Conclusion Chronic disease care is a joint commitment by health care providers and patients. This combined approach proved successful in most areas of the project, but the area of patient self management requires further improvement.

  6. Co-existence of BKV nephropathy and disseminated tuberculosis ain transplant recipient

    Directory of Open Access Journals (Sweden)

    Sarah Al-Warthan

    2014-01-01

    Full Text Available Tuberculosis (TB in renal transplant recipients presents important diagnostic difficulties because of the greater incidence of extra-pulmonary involvement, negative sputum smear results despite active disease and its atypical presentation, specifically reactivation of the latent form. BKV nephropathy was first reported in 1995, coinciding with the widespread use of immunosuppressive drugs, which can complicate the cores of 1-10% of renal transplant recipients. It is also not uncommon to find the existence of bacterial or fungal infections in the presence of an immuno-modulating virus like cytomegalovirus infection. Herewith, we describe a 67-year-old Saudi male who presented with deterioration of renal function and fever of unknown origin and was documented to have polyoma virus nephropathy and disseminated TB. To the best of our knowledge, this is the first report of such an association in the literature.

  14. Detoxification Of Ochratoxin AIN Green Coffee Beans By Physical Methods With Studying Genotoxicity Of Treated Samples

    International Nuclear Information System (INIS)

    Ochratoxin A (OTA) is potently nephrotoxic, teratogenic and carcinogenic, and the potency was varied markedly between species and sexes. Unfortunately, OTA are present due to mold contamination in different food stuffs such as coffee bean, therefore, the present study was carried out on collected imported coffee samples from super markets in Egypt. The isolation and identification proved presence of Penicilli sp. and Aspergillus sp. whereas the last one was dominant in two samples as A. niger and A. ochoruses. Determination of OTA by using HPLC analysis showed presence of high levels than the allowance levels in green coffee beans (more than 5 μg/kg; ppb). In addition, another group of collected samples as roasted coffee beans indicated the presence of high toxic concentrations of OTA. The study was then conducted on samples contain the highest OTA content by using some physical methods as gamma irradiation (5 and 10 kGy), charcoal (powder, granules), roasting (at 2000C for 7-10 min and 20 min). The results showed that proposed physical methods, mainly gamma irradiation and charcoal, could be efficient to decrease OTA in green beans coffee without produce toxic substance as well as non-significant changes in its properties. In addition, safety of resulted coffee beans after treatments were checked by ESR and genotoxicity test, which raise the preferability of gamma irradiation (10 kGy) treatment before using medium roasting to get coffee beans free from OTA

    The superplasticity of AlNp/6061Al composite, fabricated by powder metallurgy method and hot-rolled after extrusion, was investigated. The AlNp/6061Al composite exhibits an m-value of 0.49 and a maximum elongation of 438% in the strain rates ranging from 10-2-10°s-1 and at temperatures from 823K to 893K. Differential scanning calorimeter was used to ascertain the possibility of any partial melting in the vicinity of optimum superplastic temperature. These results suggested that liquid phase existed where maximum elongation was obtained.

    The effects of two different heat-treatment atmospheres,nitrogen atmosphere and reducing nitrogen atmosphere with carbon,on the properties of Y2O3-doped aluminum nitride (AlN) ceramics were investigated.The AlN powder as a raw material was synthesized by self-propagating high-temperature synthesis (SHS) and compacts were fabricated by employing powder injection molding technique.The polymer-wax binder consisted of 60 wt.% paraffin wax (PW),35 wt.% polypropylene (PP),and 5 wt.% stearic acid (SA).After the removal of binder,specimens were sintered at 1850℃ in nitrogen atmosphere under atmospheric pressure.To improve the thermal conductivity,sintered samples were reheated.The result reveals that the heat-treatment atmosphere has significant effect on the properties and secondary phase of AlN ceramics.The thermal conductivity and density of AlN ceramics reheated in nitrogen gas are 180 W·m-1 K-1 and 3.28 g,cm-3 and the secondary phase is yttrium aluminate.For the sample reheated in reducing nitrogen atmosphere with carbon,the thermal conductivity and density are 173 W.m-1.K-1 and 3.23 g·cm-3,respectively,and the secondary phase is YN.

    HPV infections have been implicated in the pathogenesis of anal cancers. The mode of infection and subsequent transformation resembles very much the pathogenesis of cervical and other HPV-associated cancers. The molecular dissection of individual steps required to achieve cellular transformation within an HPV-infected cell led to the identification of novel biomarkers that make it possible to identify HPV-transformed cells with substantially higher precision in comparison to conventional methods. Since effective antiretroviral therapy allows for possible long-term survival of HIV-infected individuals who are at very high risk to develop HPV-associated cancers in the anogenital tract, these new developments have become increasingly relevant for practicing dermatologists and proctologists. We here briefly review the basic concepts and some clinical applications of this recent research.

    Magnetic behavior and structure of V-doped AlN (Al{sub 1-x}V{sub x}N) films with various V concentrations (x = 0.03-0.36) were studied. These films exhibit paramagnetic behavior in the temperature range of 10-300 K for all x. These films have only wuerzite-type AlN phase for the range of x below 0.20. For x of 0.36, coexistence of wuerzite-type AlN phase and secondary phase is observed.

    A completely new type of actuator - one that is proposed for use in a variety of environments from sea to land to air to space - has been designed, patented, built, and tested. The actuator is loosely based on the principle of the internal combustion engine, except that it is a completely closed system, only requiring electrical input, and the working fuel is water. This paper outlines the theory behind the electrolysis- and ignition-based cycle upon which the actuator operates and describes the performance capability test apparatus and results for the actuator. A mechanism application that harnessed the unit s power to twist a scaled rotor blade is also highlighted.

    The objective of this project is to apply whole-tree harvesting method to Finnish timber harvesting conditions in order to lower the harvesting costs of energy wood and timber in spruce-dominant final cuttings. In Finnish conditions timber harvesting is normally based on the log-length method. Because of small landings and the high level of thinning cuttings, whole-tree skidding methods cannot be utilised extensively. The share of stands which could be harvested with whole-tree skidding method showed up to be about 10 % of the total harvesting amount of 50 mill. m{sup 3}. The corresponding harvesting potential of energy wood is 0,25 Mtoe. The aim of the structural measurements made in this project was to get information about the effect of different hauling methods into the structural response of the tractor, and thus reveal the possible special requirements that the new whole-tree skidding places forest tractor design. Altogether 7 strain gauge based sensors were mounted into the rear frame structures and drive shafts of the forest tractor. Five strain gauges measured local strains in some critical details and two sensors measured the torque moments of the front and rear bogie drive shafts. Also the revolution speed of the rear drive shaft was recorded. Signal time histories, maximum peaks, Time at Level distributions and Rainflow distributions were gathered in different hauling modes. From these, maximum values, average stress levels and fatigue life estimates were calculated for each mode, and a comparison of the different methods from the structural point of view was performed

    Full Text Available Measurements of molar volume, refraction index and dynamic viscosity in mixtures of fatty acids or triglycerides and trichloroethylene, tetrachloroethylene and hexane were realized. Temperature range studied was 278-313 K each 5 K. The relationship between molar volume and molar fraction show high correlation coefficient In fatty acids with trichloroethylene and tetrachloroethylene mixtures. On the other hand, hexane mixtures show little contractions of molar volume at low molar fractions. Triglyceride mixtures present important deviations with regard to the ideality of the molar volume. The adjusts obtained for the molar volume values versus temperature are acceptable, calculating the coefficients of thermal expansion of the studied mixtures. Equally, the adjust of the experimental results of viscosity for two prediction equations are studied: one of additive type and the other of parabolic type.

    Se han realizado medidas del volumen molar, índice de refracción y viscosidad dinámica en el intervalo de temperatura de 278 K a 313 K cada 5 K, a mezclas de ácidos grasos o triglicéridos con tricloroetileno, tetracloroetileno y hexano. Las mezclas de ácidos grasos con tricloroetileno y tetracloroetileno, presentan unos altos coeficientes de correlación para los valores del volumen molar frente a la fracción molar, mientras que las mezclas con hexano, a fracciones molares bajas, manifiestan una pequeña contracción del volumen molar. Las mezclas de triglicéridos presentan importantes desviaciones con respecto a la Idealidad del volumen molar. Los ajustes obtenidos para los valores del volumen molar frente a la temperatura son aceptables, determinándose los valores del coeficiente de dilatación volumétrica a presión constante de las mezclas estudiadas. Igualmente se ha estudiado el ajuste de los resultados experimentales de viscosidad a dos ecuaciones de predicción: una del tipo aditiva y otra del tipo parabólico.

    The obtention of copper from primary resources by solvent extraction has been developed continuously over the past 25-30 years, entailing a continuous effort both of research and development and being one of the biggest successes in the industrial development of a given metal. The success of this operation was not possible without the corresponding developments, at the same time, of the two accompanying operations (leaching and electro wining), which perfectly coupled in the operational sequence. The recovery of copper by means of these hydrometallurgical processes is firmly established and being reflecting in the growing number of operational plants under construction and/or commissioned until the beginning of the XXI century. This work presents data on the successfully application of the sequence of operations on the recovery of a metal: copper (Author) 19 refs.

  15. Nitric oxide as a mediator of gastrointestinal mucosal injury?—Say it ain't so

    Directory of Open Access Journals (Sweden)

    Paul Kubes

    1995-01-01

    Full Text Available Nitric oxide has been suggested as a contributor to tissue injury in various experimental models of gastrointestinal inflammation. However, there is overwhelming evidence that nitric oxide is one of the most important mediators of mucosal defence, influencing such factors as mucus secretion, mucosal blood flow, ulcer repair and the activity of a variety of mucosal immunocytes. Nitric oxide has the capacity to down-regulate inflammatory responses in the gastrointestinal tract, to scavenge various free radical species and to protect the mucosa from injury induced by topical irritants. Moreover, questions can be raised regarding the evidence purported to support a role for nitric oxide in producing tissue injury. In this review, we provide an overview of the evidence supporting a role for nitric oxide in protecting the gastrointestinal tract from injury.

    Effects on AlGaN/GaN high-electron-mobility transistor structure of a high-temperature AlN buffer on sapphire substrate have been studied by high-resolution x-ray diffraction and atomic force microscopy techniques. The buffer improves the microstructural quality of GaN epilayer and reduces approximately one order of magnitude the edge-type threading dislocation density. As expected, the buffer also leads an atomically flat surface with a low root-mean-square of 0.25 nm and a step termination density in the range of 10{sup 8} cm{sup -2}. Due to the high-temperature buffer layer, no change on the strain character of the GaN and AlGaN epitaxial layers has been observed. Both epilayers exhibit compressive strain in parallel to the growth direction and tensile strain in perpendicular to the growth direction. However, an high-temperature AlN buffer layer on sapphire substrate in the HEMT structure reduces the tensile stress in the AlGaN layer.

    Background While recognizing the etiology of community-acquired pneumonia is necessary for formulating local antimicrobial guidelines, limited data is published about this etiology in Egyptian pediatric patients. Objectives To determine the frequency of bacterial and viral pathogens causing community-acquired pneumonia (CAP) among immunocompetent Egyptian infants and preschool children. Methods Ninety infants and preschool-age children admitted to our hospital with CAP were prospectively included in the study. Etiological agents were identified using conventional bacteriological identification methods and IgM antibodies detection against common atypical respiratory bacteria and viruses. Results An etiology was identified in 59 patients (65.5%). Bacterial pathogens were detected in 43 (47.8%) of the cases while viral pathogens were detected in 23 (25.5%). Coinfection with more than one etiologic agent was evident in seven patients (7.8%). The most common typical bacterial cause of pneumonia was Staphylococcus aureus (n = 12, 13.3%), followed by Streptococcus pneumoniae and Klebsiella pneumoniae (n = 7, 7.8%, each). The commonest atypical bacterium was Mycoplasma pneumoniae (n = 10, 11.1%), whereas the commonest viral etiology was influenza viruses (n = 11, 12.2%). Conclusion Although we could not determine the causative agent in some studied cases, this study provides preliminary data regarding the spectrum and frequency of microorganisms causing CAP in Egyptian infants and preschool children.

  10. If it ain't broke, don't price fix it: the OFT and the PPRS.

    The Office of Fair Trading (OFT) Report on the UK Pharmaceutical Price Regulation Scheme (PPRS) recommends that when the current five-year PPRS expires in 2010 it be replaced with 'value-based pricing' which involves pre-launch centralised government price setting based on a cost-per-QALY threshold plus periodic ex post reviews. I examine the validity of the OFTs criticisms of the existing PPRS, review its proposals and propose an alternative way forward. I conclude that PPRS has performed well as a procurement bargain between industry and the UK government. It does not, however, incentivise efficient relative prices. That is not its job. I identify a number of problems with the OFT proposals. I recommend that key elements of a reformed UK pharmaceutical environment for 2010 should include an expanded role for HTA but with companies retaining freedom to set prices at launch; HTA use targeted via a contingent value of information approach; a retained backstop PPRS, perhaps moving to an RPI-X type control; the use of risk sharing and non-linear pricing arrangements; measures to ensure more effective therapeutic switching at local level; and measures to improve the take up of cost-effective treatments.

    2010-01-01

    Cole Porter (1891-1964), an American musical icon, has been internationally acknowledged as one of the most cosmopolitan, sophisticated, elegant and influential composer-lyricists of the 20th century. Born in Indiana and raised in wealth and privilege, he attended both Yale and Harvard universities where he honed his song-writing skills. In his 800 tunes, many of which became smash hits, he blended fresh, witty, urbane and colloquial lyrics with catchy, singable melodies. He composed musical scores for both Broadway stage and Hollywood movies, but focused on the former. While Porter enjoyed penning comic songs, he rarely had them published. In 1946, Cole wrote the music and lyrics for a Broadway show entitled Around the World in Eighty Days. Deemed a failure, it closed after only 75 performances. One light-hearted ditty, "Snagtooth Gertie", which he composed for the show, was never used. The lyrics are presented for the first time in this paper.

    Recently, a novel approach towards semi-quantitative IT security risk assessment has been proposed in the draft IEC 62443-3-2. This approach is analyzed from several different angles, e.g. embedding into the overall standard series, semantic and methodological aspects. As a result, several systematic flaws in the approach are exposed. As a way forward, an alternative approach is proposed which blends together semi-quantitative risk assessment as well as threat and risk analysis.

  20. Development of Production PVD-AIN Buffer Layer System and Processes to Reduce Epitaxy Costs and Increase LED Efficiency

    Energy Technology Data Exchange (ETDEWEB)

    Cerio, Frank

    2013-09-14

    The DOE has set aggressive goals for solid state lighting (SSL) adoption, which require manufacturing and quality improvements for virtually all process steps leading to an LED luminaire product. The goals pertinent to this proposed project are to reduce the cost and improve the quality of the epitaxial growth processes used to build LED structures. The objectives outlined in this proposal focus on achieving cost reduction and performance improvements over state-of-the-art, using technologies that are low in cost and amenable to high efficiency manufacturing. The objectives of the outlined proposal focus on cost reductions in epitaxial growth by reducing epitaxy layer thickness and hetero-epitaxial strain, and by enabling the use of larger, less expensive silicon substrates and would be accomplished through the introduction of a high productivity reactive sputtering system and an effective sputtered aluminum-nitride (AlN) buffer/nucleation layer process. Success of the proposed project could enable efficient adoption of GaN on-silicon (GaN/Si) epitaxial technology on 150mm silicon substrates. The reduction in epitaxy cost per cm{sup 2} using 150mm GaN-on-Si technology derives from (1) a reduction in cost of ownership and increase in throughput for the buffer deposition process via the elimination of MOCVD buffer layers and other throughput and CoO enhancements, (2) improvement in brightness through reductions in defect density, (3) reduction in substrate cost through the replacement of sapphire with silicon, and (4) reduction in non-ESD yield loss through reductions in wafer bow and temperature variation. The adoption of 150mm GaN/Si processing will also facilitate significant cost reductions in subsequent wafer fabrication manufacturing costs. There were three phases to this project. These three phases overlap in order to aggressively facilitate a commercially available production GaN/Si capability. In Phase I of the project, the repeatability of the performance was analyzed and improvements implemented to the Veeco PVD-AlN prototype system to establish a specification and baseline PVD-AlN films on sapphire and in parallel the evaluation of PVD AlN on silicon substrates began. In Phase II of the project a Beta tool based on a scaled-up process module capable of depositing uniform films on batches of 4”or 6” diameter substrates in a production worthy operation was developed and qualified. In Phase III, the means to increase the throughput of the PVD-AlN system was evaluated and focused primarily on minimizing the impact of the substrate heating and cooling times that dominated the overall cycle time.

    The objective of this project was to apply the whole-tree harvesting method to the Finnish timber harvesting condition in order to reduce the harvesting costs of both energy wood and timber in spruce-dominant final cuttings. In the Finnish condition timber harvesting is normally based on log-length method. According to the study, the best way to operate in logging stage of the whole-tree harvesting method is to cut other tree species than spruce and rotten spruces into bolts. These bolts will be forwarded to the road-side piles and only spruce whole-trees will be skidded. At the road-side, the cheapest alternative would be processing of whole- trees into log-sections and pulpwood. In the Finnish harvesting conditions, 12-22 % of final cuttings would be suitable for whole- tree harvesting. The best utilization possibilities are in the southern and central Finland. According to the study, it is not economical to specialize in the whole-tree harvesting, as the share of suitable stands is too small. Contamination of the crown mass in the skidding lowers the amount of energy wood by 20-30 %, if the slash is to be chipped. The simulation study showed that the whole- tree buffer should be kept quite small especially in stands, where the skidding distance is short, the share of spruce is high and the stems are big. According to the structural measurements of the crane and chassis, the average stress levels are higher in skidding than in forwarding. However, the fatigue life estimates showed, that the difference between these different harvesting methods is insignificant, when the share of stand harvested with whole-tree skidding method is not higher than 20 %.

    Full Text Available The thermoreversible gelation of three triblock copolymers polystyrene-bpoly( ethylene/butylene-b-polystyrene, with different molar mass and a similar chemical composition, in n-octane was studied. The solvent is selective for the middle poly(ethylene/butylene block of the copolymers. The influence of the molar mass of the three copolymers on the gelation and on the mechanical properties of the gels was analysed. The sol-gel transition temperatures, Tgel, have been determined and they increase with the copolymer concentration and the copolymer molar mass. On the other hand, the mechanical properties of the different gels were examined through oscillatory shear and compressive stress relaxation measurements. The concentration dependence of the elastic storage modulus, G’, for the three copolymer studied fit a sole straight line in a doublelogarithmic scale and its slope (2.22 is close to that expected for systems in good solvents (2.25. As the temperature is near to the sol-gel transition temperature, the elastic modulus are smaller and the relaxation rates are higher.

Se ha determinado la temperatura de formación de los geles, Tgel, concluyendo que éstas aumentan con la concentración y el peso molecular del copolímero. Por otra parte, se han medido las propiedades mecánicas de los geles empleando ensayos de torsión y relajación de tensión, en función de la concentración de copolímero. La dependencia doble logarítmica del módulo G' con la concentración de copolímero para los tres SEBS se ajusta a una línea recta de pendiente 2,22, próxima a la predicha para geles preparados químicamente (2,25. Cuanto más próxima está la temperatura de medida a la de formación del gel los módulos elásticos obtenidos para los tres copolímeros son menores y la relajación es más rápida.

    Full Text Available A regression study of Andrade, Krone, McAllister and Hildebrand equations with experimental data of viscosity of mixtures of triglycerides or free fatty acids and trichloroethylene, tetrachloroethylene and hexane was carried out. Temperature range studied was 278-313 K in steps of 5K.
    The results showed that the Hildebrand equation presents the best fit for all the viscosity data of the mixtures studied, tending towards a lineal or parabolic function of its parameters.
    Andrade and Krone equations presented acceptable fits for all mixtures studied except the fatty acids and hexane mixture. The McAllister equation was applicable only to mixtures with tetrachloroethylene.

    Los resultados obtenidos indican que el mejor ajuste de los datos experimentales de viscosidad lo presenta la ecuación de Hildebrand, buscándose una función lineal o parabólica con la fracción molar de sus dos parámetros.
    Las ecuaciones de Andrade y Krone presentan un ajuste aceptable para todas las mezclas estudiadas excepto para las de ácidos grasos en hexano y la ecuación de McAllister es únicamente aplicable a las mezclas con tetracloroetileno.

    The colonization of a new planet will inevitably bring about new bioethical issues. One is the possibility of pregnancy during the mission. During the journey to the target planet or moon, and for the first couple of years before a colony has been established and the colony has been accommodated for children, a pregnancy would jeopardize the safety of the crew and the wellbeing of the child. The principal concern with a pregnancy during an interplanetary mission is that it could put the entire crew in danger. Resources such as air, food, and medical supplies will be limited and calculated to keep the crew members alive. We explore the bioethical concerns of near-future space travel.

    Mobile technology is very prevalent in Kenya-mobile phone penetration is at 88% and mobile data subscriptions form 99% of all internet subscriptions. While there is great potential for such ubiquitous technology to revolutionise access and quality of healthcare in low-resource settings, there have been few successes at scale. Implementations of electronic health (e-Health) and mobile health (m-Health) technologies in countries like Kenya are yet to tackle human resource constraints or the political, ethical and financial considerations of such technologies. We outline recent innovations that could improve access and quality while considering the costs of healthcare. One is an attempt to create a scalable clinical decision support system by engaging a global network of specialist doctors and reversing some of the damaging effects of medical brain drain. The other efficiently extracts digital information from paper-based records using low-cost and locally produced tools such as rubber stamps to improve adherence to clinical practice guidelines. By bringing down the costs of remote consultations and clinical audit, respectively, these projects offer the potential for clinics in resource-limited settings to deliver high-quality care. This paper makes a case for continued and increased investment in social enterprises that bridge academia, public and private sectors to deliver sustainable and scalable e-Health and m-Health solutions.

  20. It Ain't the Heat, It's the Humanity: Evidence and Implications of a Knowledge-Based Consensus on Man-Made Global Warming

    Science.gov (United States)

    Jacobs, P.; Cook, J.; Nuccitelli, D. A.

    2013-12-01

    One of the most worrisome misconceptions among the general public about climate change is a belief that scientists disagree not only about the cause of the present climate change, but also whether or not the planet is currently warming. Recent surveys have demonstrated that an overwhelming consensus exists, both within the scientific literature and among scientists with climate expertise, that the planet is warming and humans are driving this climatic change. This disconnect, or 'consensus gap', between scientific agreement and public belief has significant consequences for public understanding of the reality and cause of climate change, as well as support for potential solutions. Ensuring that the consensus message is not simply broadcast but is also accepted as legitimate by the public appears to be a primary education and communications opportunity. While the existence of a consensus is not itself evidence of a position's truth, according to Miller (2013) scientific consensus can be taken as evidence that a position is true if it is 'knowledge-based', satisfying the conditions of social calibration, apparent consilience of evidence, and social diversity. We demonstrate that the scientific consensus on anthropogenic climate change is knowledge-based, satisfying Miller's criteria. In so doing, we hope to increase confidence in its use as an education and communications tool, and assure the public of its validity. We show the consensus is socially calibrated, based on common evidential standards, ontological schemes, and shared formalism. We establish that consilience of evidence points overwhelmingly to the reality of anthropogenic climate change by examining the evidence from several perspectives. We identify unique fingerprints expected as a result of increased greenhouse forcing, eliminate potential natural drivers of climate change as the cause of the present change, and demonstrate the consistency of the observed climate response with known changes in natural and manmade forcings across a wide variety of indices. Finally, we determine that the consensus is socially diverse, being geographically and disciplinarily varied, supported within public and private institutions, and endorsed by research organizations as well as groups with obvious financial incentives to deny it, such as fossil fuel companies. Additionally, we briefly discuss examples of purported incorrect consensus in climate research, and detail how they fail to satisfy one or more aspects of Miller's criteria. We conclude by discussing the key role that knowledge-based consensus can potentially play in education, influencing public beliefs about climate change, and increasing support for solutions.

    Full Text Available Abstract Even using intensive statin monotherapy, many patients fail to achieve all the desired lipid goals and remain at high residual risk of cardiovascular events. In view of the still unproven decisively intensive "statin as monotherapy" strategy and "residual risk" concept, it is logical to ask whether other strategies, particularly fibrate/statin combination therapy, could be more beneficial and safer. A clear benefit of fibrate monotherapy did emerge previously among patients with atherogenic dyslipidemia (particularly high triglycerides and low high density lipoprotein cholesterol [HDL-C] typically present in the metabolic syndrome and type 2 diabetes. In contrast, in patients without atherogenic dyslipidemia this favorable effect was not demonstrated. The Action to Control Cardiovascular Risk in Diabetes (ACCORD study investigated whether combination therapy with a statin plus a fibrate, as compared with statin monotherapy, would reduce the risk of cardiovascular disease in patients with type 2 diabetes mellitus. However, relevant patients with atherogenic dyslipidemia represented less than 17 percent of the ACCORD Lipid population (941 out of 5518 patients. In this prespecified subgroup, the patients benefited from fenofibrate therapy in addition to simvastatin similar to the previous "fibrate's as monotherapy" trials: the primary outcome rate was 12.4% in the fenofibrate group, versus 17.3% in the placebo group (28% crude HR reduction, CI less than1, e.g. statistically significant findings. Among all other 4548 patients without atherogenic dyslipidemia such rates were 10.1% in both fenofibrate and placebo study groups. Authors concluded that in the overall cohort of patients the combination of fenofibrate and simvastatin did not reduce the rate of the cardiovascular events as compared with simvastatin alone. Thus, their results do not support the routine use of combination therapy with fenofibrate and simvastatin to reduce cardiovascular risk in the general patients with type 2 diabetes. A recent large meta-analysis regarding effects of fibrates on cardiovascular outcomes noted greater effect sizes in trials that recorded a higher mean baseline triglyceride concentration (p = 0.030. As expected, in a so called "general population", reflecting a blend of effects in patients with and without atherogenic dyslipidemia, a mean "diluted" effect of fibrate therapy was reduced, but still producing a significant 10% relative risk (RR decrease in major cardiovascular events (p = 0.048 and a 13% RR reduction for coronary events (p It should be pinpointed that the epidemiological characteristics of the ACCORD Lipid study depart from those seen in real clinical practice: among people with type 2 diabetes, there is a high prevalence of atherogenic dyslipidemia and metabolic syndrome. For example, an analysis of NHANES III data in adults aged ≥50 years showed that approximately 86% of patients with type 2 diabetes also had the metabolic syndrome. Therefore, an importand finding of ACCORD Lipid study was the observation that fibrates may lead to cardiovascular risk reduction in patients with atherogenic dyslipidemia not only as monotherapy but in combination with statins as well. In conclusion, in patients with atherogenic dyslipidemia (high triglycerides and low HDL-C, fibrates -- either as monotherapy or combined with statins - were associated with reduced risk of cardiovascular events. In patients without dyslipidemia this favorable effect - as expected - was absent.

    Evidence-based interventions have been developed and used to prevent HIV infections among black men who have sex with men (MSM) in Canada and the United States; however, the degree to which interventions address racism and other interlocking oppressions that influence HIV vulnerability is not well known. We utilize integrative antiracism to guide a review of HIV prevention intervention studies with black MSM and to determine how racism and religious oppression are addressed in the current intervention evidence base. We searched CINAHL, PsychInfo, MEDLINE and the CDC compendium of evidence-based HIV prevention interventions and identified seventeen interventions. Three interventions targeted black MSM, yet only one intervention addressed racism, religious oppression, cultural assets and religious assets. Most interventions' samples included low numbers of black MSM. More research is needed on interventions that address racism and religious oppression on HIV vulnerability among black MSM. Future research should focus on explicating mechanisms by which multiple oppressions impact HIV vulnerability. We recommend the development and integration of social justice tools for nursing practice that aid in addressing the impacts of racism and other oppressions on HIV vulnerability of black MSM.

    2013-11-01

    Public sector organisations are facing one of the most difficult financial periods in history and local decision-makers are tasked with making tough rationing decisions. Withdrawing or limiting services is an emotive and complex task and something the National Health Service has always found difficult. Over time, local authorities have gained significant experience in the closure of care homes - an equally complex and controversial issue. Drawing on local knowledge and best practice examples, this article highlights lessons and themes identified by those decommissioning care home services. We believe that such lessons are relevant to those making disinvestment decisions across public sector services, including health-care. The study employed semi-structured interviews with 12 Directors of Adult Social Services who had been highlighted nationally as having extensive experience of home closures. Interviews were conducted over a 2-week period in March 2011. Results from the study found that having local policy guidance that is perceived as fair and reasonable was advocated by those involved in home closures. Many local policies had evolved over time and had often been developed following experiences of home closures (both good and bad). Decisions to close care home services require a combination of strong leadership, clear strategic goals, a fair decision-making process, strong evidence of the need for change and good communication, alongside wider stakeholder engagement and support. The current financial challenge means that public sector organisations need to make tough choices on investment and disinvestment decisions. Any such decisions need to be influenced by what we know constitutes best practice. Sharing lessons and experiences within and between sectors could well inform and develop decision-making practices.

    The traditional view of radio pulsar wind nebulae (PWN), encouraged by the Crab nebula's X-ray and radio morphologies, is that they are a result of the integrated history of their pulsars' wind. The radio emission should therefore be largely unaffected by recent pulsar activity, and hence minimally correlated with structures in the X-ray nebulae. Observations of several PWN, both stationary (sPWN) and rapidly moving (rPWN), now show clear morphological relationships between structures in the radio and X-ray with radio intensity variations on the order of unity. We present high-resolution X-ray and radio images of several PWN of both types and discuss the morphological relationships between the two wavebands.

    Teachers are often thought to retire early and have more stress and burnout than other human service professionals. In this article, we investigate attrition intention amongst senior teachers and senior employees of six other blue- and white-collar occupational categories using the Job Demands-Resources (JD-R) model. We followed a two-step approach. First, analysis of variance and logistic regression analysis was used to assess differences in the level of job demands, resources, and attrition intention between occupations for male and female employees separately. Subsequently, multiple group path analysis was used to assess the invariance of the JD-R model across occupational groups and genders. We used representative data gathered in Flanders among 6,810 senior employees (45 years or older). Results indicate that there are differences in the determinants of attrition intention between men and women. The differences in attrition intention are minimal between occupations once controlled for job demands and resources. In addition, the JD-R model is largely invariant across white-collar occupations and gender. We provide support for both the energetic and motivational process of the JD-R model.

    2015-04-13

    Prof. Dame Kathleen Lonsdale was one of the two first female Fellows of the Royal Society, having originally been a student of that great British scientist and Nobel Laureate William Henry Bragg. She came to fame initially for her solution of the crystal structure of hexamethyl benzene, thus demonstrating that the benzene ring was flat, of considerable importance to organic chemistry, where it had been proposed before but without proof. This was at a time when the solution of crystal structures was in its infancy, and in its day this work was considered a triumph. As a rare example then of a female physicist, Lonsdale became interested in various aspects of the diffraction of X-rays, and in particular published an important paper on a form of diffraction in which a strongly divergent source was used rather than the usual highly collimated beam. The photographs thus obtained showed a series of arcs and circles, whose positions were so sensitive that they could be used to determine the quality of crystals such as diamond, and even to calculate their lattice dimensions, and hence carbon-carbon bond lengths, to hitherto extraordinary precision. Lonsdale also became known not just as a scientist but as a peace activist and an active member of the Society of Friends. This commentary was written to celebrate the 350th anniversary of the journal Philosophical Transactions of the Royal Society.

    The considerable seasonal differences in energy consumption as well as the economic optimisation of the energy supply contracts have induced Gaz de France to develop a comprehensive research and construction programme for underground natural gas reservoirs. These reservoirs would enable the varying demands for energy to be met and at the same time mitigate the consequences of a possible failure of supply. There are two main types of underground reservoir: aquiferous reservoirs (11), salt mine reservoirs (2). The present article describes the French reservoir system and the techniques employed. The salt mine reservoir in Etrez is described in detail. It is connected to the Swiss energy network by the Etrez-Gland pipeline, thus considerably increasing possible energy reserves for Switzerland. (orig.).

    Concerns have been expressed that dust from the minerals processing facilities at Karumba Queensland Australia have resulted in elevated lead (Pb) concentrations in rain water tanks. The ores derived from the Century mine some 304 km from the port. High precision Pb isotopic measurements on environmental samples have been undertaken to evaluate the source of Pb in rainwaters and acid digests from roof wipes and gutter wipes. There does not appear to be any relationship between sample location and the processing facility but samples from the area subject to the prevailing winds show the highest contribution of Century Pb. All gutter wipes (82 to 1270 µg Pb/wipe) have contributions of Century ore ranging from 87% to 96%. The contribution of Century ore to five roof wipes (22 to 88 µg Pb/wipe) ranges from 89% to 97% and in the other two samples there is a mix of Century and Broken Hill Pb. Three of the seven rainwater have contributions of Century ore Pb ranging from 33% to 75%. Two of the other four rainwater samples have the highest water Pb concentrations of 88 and 100 µg/L and their isotopic data show Broken Hill Pb contributions ranging from 77% to 80%. The source of the Broken Hill Pb is probably from the galvanized roofing material and/or brass fittings in the rainwater tanks. The discrimination between various sources is only detectable using high precision (204)Pb-based isotopic ratios and not the now common inductively coupled plasma mass spectrometry (ICP-MS ) data presentations of the higher abundance isotopes (208)Pb, (207)Pb and (206)Pb. Isotopic results for the waters demonstrate that apportioning blame where there is an obvious point source may not always be the correct conclusion. Nevertheless the isotopic data for the gutter wipes indicates that there was widespread contamination from the processing facilities throughout the town. PMID:26907319

  8. A nickel ain't worth a dime anymore: the illusion of money and the rapid encoding of its true value.

    Directory of Open Access Journals (Sweden)

    Rongjun Yu

    Full Text Available People often evaluate money based on its face value and overlook its real purchasing power, known as the money illusion. For example, the same 100 Chinese Yuan can buy many more goods in Tibet than in Beijing, but such difference in buying power is usually underestimated. Using event related potential combined with a gambling task, we sought to investigate the encoding of both the real value and the face value of money in the human brain. We found that the self-reported pleasantness of outcomes was modulated by both values. The feedback related negativity (FRN, which peaks around 250ms after feedback and is believed to be generated in the anterior cingulate cortex (ACC, was only modulated by the true value but not the face value of money. We conclude that the real value of money is rapidly encoded in the human brain even when participants exhibit the money illusion at the behavioral level.

Two of the other four rainwater samples have the highest water Pb concentrations of 88 and 100 µg/L and their isotopic data show Broken Hill Pb contributions ranging from 77% to 80%. The source of the Broken Hill Pb is probably from the galvanized roofing material and/or brass fittings in the rainwater tanks. The discrimination between various sources is only detectable using high precision (204)Pb-based isotopic ratios and not the now common inductively coupled plasma mass spectrometry (ICP-MS ) data presentations of the higher abundance isotopes (208)Pb, (207)Pb and (206)Pb. Isotopic results for the waters demonstrate that apportioning blame where there is an obvious point source may not always be the correct conclusion. Nevertheless the isotopic data for the gutter wipes indicates that there was widespread contamination from the processing facilities throughout the town.

    Conclusion: Clinical suspicion should arise in the presence of isolated paralysis of the AIN-supplied muscles. MRI and electrodiagnostic studies will confirm the diagnosis and identify the etiology. The optimal treatment of AIN syndrome has not been established. We recommend surgical intervention in confirmed AIN syndrome from compression neuropathy, refractive to conservative therapy.

  20. Order-disorder in In3+ perovskites: The example of A(In2/3B''1/3)O3 (A=Ba, Sr; B''=W, U)

    International Nuclear Information System (INIS)

    We describe the preparation and structural characterization of four In-containing perovskites from neutron powder diffraction (NPD) and X-ray powder diffraction (XRPD) data. Sr3In2B''O9 and Ba(In2/3B''1/3)O3 (B''=W, U) were synthesized by standard ceramic procedures. The crystal structure of the W-containing perovskites and Ba(In2/3U1/3)O3 have been revisited based on our high-resolution NPD and XRPD data, while for the new U-containing perovskite Sr3In2UO9 the structural refinement was carried out from high-resolution XRPD data. At room temperature, the crystal structure for the two Sr phases is monoclinic, space group P21/n, where the In atoms occupy two different sites Sr2[In]2d[In1/3B''2/3]2cO6, with a=5.7548(2) A, b=5.7706(2) A, c=8.1432(3) A, β=90.01(1)o for B''=W and a=5.861(1) A, b=5.908(1) A, c=8.315(2) A, β=89.98(1)o for B''=U. The two phases with A=Ba should be described in a simple cubic perovskite unit cell (S.G. Pm3-bar m) with In and B'' distributed at random at the octahedral sites, with a=4.16111(1) A and 4.24941(1) A for W and U compounds, respectively. - Graphical abstract: The structure of the new uranium-based double perovskite Sr3In2UO9 is described and the true symmetry of the other title compounds are revisited. The presence of long-range ordering in the Sr samples, by contrast with the Ba perovskites, is related with the smaller unit cell and B-B distances in the Sr oxides, promoting the electrostatic repulsions between highly charged W6+ and U6+ cations as driving force for the long-range B-site ordering

    To study and characterise the MR imaging findings of lesions of the anterior interosseous nerve (AIN). Magnetic resonance imaging (MRI) findings of the forearm of ten patients referred to our institution with suspected AIN lesions were retrospectively studied. Five healthy volunteers with normal forearm MRI findings formed a control group. Two musculoskeletal radiologists assessed the forearm musculature for oedema in the distribution of the AIN, median, posterior interosseous and radial nerves on T2-weighted (T2W) fat-saturated sequences. T1-weighted (T1W) images were assessed and graded for the presence of muscle atrophy and fatty involution. Six patients had undergone surgical exploration; five of these had surgically confirmed AIN compression. Four patients had diagnoses other than AIN compression made on imaging features. Of the cases of proven AIN compression, oedema within the pronator quadratus (PQ) muscle was identified in all cases. PQ atrophy and fatty involution were seen in three (43%) surgically confirmed cases. Cases 2 and 3 also demonstrated oedema in the flexor digitorum profundus (FDP)1 and FDP2 muscles. These cases also showed oedema in the flexor-carpi radialis (FCR) and FDP3/FDP4 muscles, respectively. The four cases of non-AIN compression demonstrated muscle oedema patterns that were atypical for the AIN distribution. They included a rupture of the flexor pollicis longus (FPL) tendon, brachial neuritis, amyotrophic lateral sclerosis and compression of the proximal median nerve. MRI is a useful investigation in the diagnostic workup of AIN syndrome. AIN syndrome is likely when there is diffuse oedema of AIN innervated muscles on T2W fat-saturated images. The most reliable sign of an AIN lesion is oedema within the PQ. Oedema in the flexor carpi radialis, FDP3 and FDP4, although not in the classical distribution of the AIN, does not preclude the diagnosis of AIN syndrome. (orig.)

    Objetivo: a pesar de la alta incidencia de anemia ferropénica y de los efectos beneficiosos derivados del consumo de leche de cabra, poco se conoce, en realidad, acerca de la recuperación de la anemia mediante una dieta equilibrada acompañada de la ingesta de leche de cabra. El objetivo del presente estudio es determinar, en ratas con anemia ferropénica nutricional, los efectos de dietas elaboradas a base de leche de cabra, en comparación con la de vaca, suministradas durante 30 días, sobre la recuperación de la anemia y la eficacia de regeneración de la hemoglobina. Material y métodos: se han utilizado 40 ratas macho Wistar albina recién destetadas divididas al azar en dos grupos experimentales y alimentadas ad libitum durante 40 días con dieta AIN-93G con contenido normal de hierro (grupo control, 45 mg/kg dieta), o bajo (grupo anémico, 5 mg/kg dieta). Se toman muestras de sangre de la vena caudal para el control hematológico de la anemia. Posteriormente, cada uno de los dos grupos experimentales (control y ferrodeficiente) fueron alimentados durante 30 días con dietas elaboradas a base de leche de cabra o vaca. Al finalizar el período experimental y previa anestesia, las ratas se desangran por canulación de la aorta abdominal, y la sangre obtenida se recoge en un tubo con EDTA como anticoagulante para la posterior determinación de los parámetros hematológicos y la eficacia de regeneración de la hemoglobina. Resultados y discusión: tras el consumo de una dieta con bajo contenido en hierro durante 40 días, las ratas eran anémicas, con una concentración de hemoglobina, hematocrito, hierro sérico, volumen corpuscular medio (VCM), ferritina sérica y saturación de la transferrina bajos (p < 0,001), mientras que los niveles de plaquetas y la capacidad total de unión al hierro (TIBC) estaban elevados (p < 0,001), hallazgos consistentes con la anemia inducida experimentalmente en ratas. La eficacia de regeneración de la hemoglobina era mayor

    Using density functional theory (DFT) method with 6-31G* basis set, we have carried out the optimizing calculation of geometry, vibrational frequency and thermodynamical stability for(AIN)n+ and (AIN)n- (n =1-15) clusters. Moreover, their ionic potential (IP) and electron affinity(EA) were discussed. The results show that the electrical charge condition of the cluster has a relatively great impact on the structure of the cluster and with the increase of n, this kind of impactis reduced gradually. There are no AI-AI and N-N bonds in the stable structure of (AIN)n+ or (AIN)n-, and the AI-N bond is the sole bond type. The magic number regularity of (AIN)n+, and (AIN)n- is consistent with that for (AIN)n, indicating that the structure with even n such as 2, 4,6, … is more stable. In addition, (AIN)10 has the maximal ionization power (9.14 eV) and the minimal electron affinity energy (0.19 eV), which manifests that (AIN)10 is more stable than other clusters.

    Acute interstitial nephritis (AIN) secondary to trimethoprim-sulfamethoxazole (TMP-SMX) is well documented as a cause of acute renal failure in native kidneys. TMP-SMX is the standard prophylactic agent against pneumocystis carinii (PCP) used in the early post-transplant period, however, it has to date only been indirectly associated with AIN in renal allografts. DESIGN, SETTING, PARTICIPANTS AND MEASUREMENTS: We describe eleven renal transplant patients with acute allograft dysfunction in whom a transplant biopsy demonstrated primary histopathologic features of allergic AIN, all of whom were receiving TMP-SMX in addition to other medications known to cause AIN.

    AIN nanowires with a hexagonal structure were synthesized using an improved arc-discharge method and their microstructures were characterized using a high-resolution transmission electron microscope. The synthesized AIN nanowires were of various shapes. Their diameters ranged from 20 to 110 nm and the lengths were up to 20μm. Most of the AIN nanowires were coated by an amorphous layer of aluminum oxide. Fabrication yield was about several grams. The growth mechanism was considered to be a vapor-liquid-solid process and an Al droplet formed on the top of as-grown AIN nanowire played a role of catalyst.

    Full Text Available Petroleum derived n-hexane is commercially used in solvent extraction plants due to its higher extraction efficiency in spite of the fact that it is graded as highly toxic and hazardous. The present study is based on the use of both a much safer and non toxic solvent ethanol and n-hexane for the extraction of oil from cottonseed. The extraction data were obtained by varying temperature, solvent-solid ratio and particle size, to compare the extraction efficiency of both ethanol and n-hexane. The data show that nearly the same amount of extraction is possible at a higher solvent-solid ratio for both the solvents. This study has established that the kinetics of oil extraction follows a second order reaction mechanism. The thermodynamic analysis of the data shows that both ΔHº and ΔSº are positive, and ΔGº is negative indicating that the extraction process is endothermic, irreversible, and spontaneous.

    El n-hexano derivado del petróleo es comercialmente usado en plantas de extracción con disolventes debido a su mayor eficiencia de extracción, a pesar de que está calificado como altamente tóxico y peligroso. El presente estudio está basado en el uso de etanol, disolvente mucho más seguros y no tóxico, y n-hexano en la extracción de aceite de algodón. Los datos de extracción fueron obtenidos variando la temperatura, la proporción sólido-disolvente y el tamaño de partícula, para comparar la eficiencia de extracción del etanol y del hexano. Los datos muestran que casi la misma cantidad de extracción es posible para ambos disolventes a la proporción más alta de sólido-disolvente. Este estudio es capaz de establecer que las cinéticas de extracción de aceite siguen un mecanismo de reacción de segundo orden. El análisis termodinámico de los datos mostró que ΔHº and ΔSº son positivas, y ΔGº es negativa, indicando que el proceso de extracción es endotérmico, irreversible y espontáneo.

    2009-01-01

    The effects of Y_2O_3 and Er_2O_3 on the sintering behaviors, thermal properties and microstructure of AIN ceramics were investigated. The ex-perimental results show that the sintering temperature can be decreased; the relative density and thermal behavior can be improved by adding rare earth oxide in AIN ceramics. For AIN ceramics with 3 wt.% Er_2O_3 additive, the relative density is 98.8%, and the thermal conductivity reaches 106 W·m~(-1)·K~(-1). The microstructure research found that no obvious aluminum erbium oxide was found in AIN ceramics doped with 3 wt.% Er_2O_3, which favored the improvement of the thermal conductivity of AIN ceramics.

    AIN and Al2N2 have been observed in the record of time-of-flight mass-spectra as positive ions. Associating with density functional theory(DFT) B3LYP method with 6-31G* basis set, we have carried out the optimizing calculations of the geometry, electronic state and vibrational frequency for (AIN)n (n = 1-15) clusters, moreover, discussed the character of the chemical bond and thermodynamical stability and explained the experimental mass spectra. The results show that there do not exist AI-AI and N-N bonds and only exists AI-N bond in the ground state structures of (AIN)n clusters; and the "magical number" regularity of (AIN)n is those whose atom number Is 4, 8, 12,16, 20, etc, all of which are times of four.

  8. Risk Factors for the presence of anal intraepithelial neoplasia in HIV+ men who have sex with men.

    Full Text Available OBJECTIVE: Anal Intraepithelial Neoplasia (AIN is present in the majority of HIV+ men who have sex with men (MSM and routine AIN-screening is subject of discussion. In this study we analysed a wide range of potential risk factors for AIN in order to target screening programs. METHODS: We screened 311 HIV+ MSM by high resolution anoscopy, with biopsies of suspect lesions. HIV-parameters, previous sexual transmitted infections (STI's, anal pathology, sexual practices and substance use were analysed in relation to AIN by uni- and multivariable logistic regression. RESULTS: AIN (any grade was found in 175/311 MSM (56%, high grade (HGAIN in 30%. In the univariable analysis, years since HIV diagnosis, years of antiretroviral therapy (cART and anal XTC use decreased AIN risk, while a history of anogenital warts and use of GHB (γ-hydroxybutyric acid increased this risk. In the multivariable analysis three parameters remained significant: years of cART (OR=0.92 per year, p=0.003, anal XTC use (OR=0.10, p=0.002 and GHB use (OR=2.60, p=0.003. No parameters were significantly associated with HGAIN, but there was a trend towards increased risk with anal enema use prior to sex (>50 times ever; p=0.07 and with a history of AIN (p=0.06. CD4 count, STI's, anal pathology, smoking, number of sex partners and anal fisting were not associated with (HGAIN. CONCLUSION: GHB use increases the risk for AIN, while duration of cART and anal XTC use are negatively correlated with AIN. Given the high prevalence of AIN in HIV+ MSM, these associations are not helpful to guide a screening program.

    本文采用燃烧合成工艺,在100MPa氮气的气相热等静压作用下,制备了致密的AlN-TiB2系陶瓷,相对密度达95%,抗弯强度达350 MPa。研究表明,Al-N2-TiB2体系燃烧过程中,当反应温度升至660℃时Al熔化,1 000℃时Al开始剧烈挥发,与N2迅速反应形成AlN。在反应区高温下熔融Al在TiB2表面发生浸流现象,使Al的反应层厚度减小,反应面积增大,反应速度提高。同时Al的漫流使燃烧反应区发生液相烧结,从而使反应区孔隙率显著下降,当开气孔闭合时在气相压力作用下形成致密产物。随着TiB2含量增加,液相烧结作用增强,产物致密度提高。Al-N2-TiB2体系燃烧合成的致密化主要发生在燃烧波蔓延方向,具有明显的方向性。%Compact AlN/TiB2 ceramics was fabricated by combustion synthesis of Al particles in the super-high pressure nitrogen (100 MPa). Maximal relative density of 95% and maximal bending strength of 350 MPa are reached for the products. In the SHS process of Al-N2-TiB2 system, when the temperature is up to 660 ℃, metal Al melts and volatilizes strongly at 1 000 ℃. Al vapor vapidly reacts with N2 to form AlN. At high temperature melted Al spread over the TiB2 particle surface, which lead to a decrease of reaction layer thickness of melted Al, an increase of reaction surface and speed, and liquid sinter occurs.As a result, the porosity of the reaction zone decreases significantly. With increasing of TiB2 content in the original powder system, liquid sintering decreases, and the relative density, bending strength and fracture toughness of the products are increased. In Al- N2 - TiB2 system, SHS-densification has apparent tropism of mainly occurs along the combustion front.

  14. Allergic Interstitial Nephritis Manifesting as a Striated Nephrogram

    2015-01-01

    Full Text Available Allergic interstitial nephritis (AIN is an underdiagnosed cause of acute kidney injury (AKI. Guidelines suggest that AIN should be suspected in a patient who presents with an elevated serum creatinine and a urinalysis that shows white cells, white cell casts, or eosinophiluria. Drug-induced AIN is suspected if AKI is temporally related to the initiation of a new drug. However, patients with bland sediment and normal urinalysis can also have AIN. Currently, a definitive diagnosis of AIN is made by renal biopsy which is invasive and fraught with risks such as bleeding, infection, and hematoma. Additionally, it is frequently unclear when a kidney biopsy should be undertaken. We describe a biopsy proven case of allergic interstitial nephritis which manifested on contrast enhanced Magnetic Resonance Imaging (MRI as a striated nephrogram. Newer and more stable macrocyclic gadolinium contrast agents have a well-demonstrated safety profile. Additionally, in the presentation of AKI, gadolinium contrast agents are safe to administer in patients who demonstrate good urine output and a downtrending creatinine. We propose that the differential for a striated nephrogram may include AIN. In cases in which the suspicion for AIN is high, this diagnostic consideration may be further characterized by contrast enhanced MRI.

    High translucency is one of the excellent properties of AIN ceramics because of its wide optical band gap energy of 6.2 eV. We have achieved success in producing AIN ceramic tube of 98% total visible light transmittance at 0.6 mm thick tube wall by applying an improved sintering technique. This AIN ceramic was produced by sintering at 1880℃ using Ca3Al2O6 as a sintering additive and in reduction atmosphere to remove the sintering additive from the final sintered material. After the sintering, the annealing with Al2o3 was carried out to improve the transmittance of AIN ceramics. The amount of metal impurities and carbon were 27ppm and 100ppm, respectively. It is noteworthy that the amount of oxygen in AIN ceramics after the annealing was 0.36wt% which was higher than the 0.07wt% of the as-sintered AIN ceramics. Therefore, total transmittance was improved by the oxygen doping. On the other hand, thermal conductivity of AIN after the annealing was lowered by 35% compared with that of as-sintered AIN. Positron Annihilation Lifetime (PAL) measurement was applied to investigation of a relationship between the total transmittance and lattice defects. The present PAL results confirms the presence of negatively charged atomic-size vacancies that is aluminum site vacancies and also sug-gests the increase in the concentration of the vacancies after the annealing compared with that of the as-sintered material. However, it can be concluded that there is no relation between aluminum site va-cancies and the light transmittance of AIN ceramics.

    Full Text Available Spent nickel catalyst (SNC have the potential of insulting the quality of the environment in a number of ways. The disposal of SNC will have a pollution effect. Optimum recovery of fat from SNC , could save the environment and reduce the oil loss. Hexane has been the solvent of choice for oil extraction. Alternative solvents that are considered safer have been evaluated. Hexane, isopropanol, ethanol, and heptane were examined using soxhlet extraction. While hexane was more efficient in oil recovery from SNC, isopropanol proved to be very good, to clarifying separation of oil from waste material and also provide high solvent recovery compared to other solvents. Isopropanol extraction with chill provided separation of miscella into two phases: lower oil–rich and an upper solvent – rich. It saved much energy of vaporization for distilling. An aqueous extraction process with immiscible solvent assisted was tested. Solvent like hexane added to SNC, and water added later with continuous stirring. The mixture was stirred for about 30 minutes, prior to centrifugation. Aqueous process extracted less amount of oil compared to solvent extraction.El catalizador agotado de níquel (SNC tiene el potencial de dañar la calidad del medio ambiente de diversas formas. El depósito de SNC tendrá un efecto de polución. La recuperación óptima de la grasa a partir del SCN, podría conservar el medio ambiente y reducir la pérdida de aceite. El hexano ha sido el disolvente elegido para la extracción del aceite. También se han evaluado disolventes alternativos que son considerados seguros. Se han examinado hexano, isopropanol, etanol y heptano usando extracción con soxhlet. Mientras que el hexano fue el mas eficaz en la recuperación del aceite, el isopropanol demostró ser muy bueno para aclarar la separación del aceite a partir de la materia residual y también proporcionó una alta recuperación del disolvente en comparación con los otros

    AIN/GaN superlattice buffer is inserted between GaN epitaxial layer and Si substrate before epitaxial growth of GaN layer. High-quality and crack-free GaN epitaxial layers can be obtained by inserting AIN/GaN superlattice buffer layer. The influence of AIN/GaN superlattice buffer layer on the properties of GaN films are investigated in this paper. One of the important roles of the superlattice is to release tensile strain between Si substrate and epilayer. Raman spectra show a substantial decrease of in-plane tensile strain in GaN layers by vising AIN/GaN superlattice buffer layer. Moreover, TEM cross-sectional images show that the densities of both screw and edge dislocations are significantly reduced. The GaN films grown on Si with the superlattice buffer also have better surface morphology and optical properties.

    The aim of the study was to determine the incidences of anal cancer and high-grade anal intraepithelial neoplasia (AIN2/3) over time in Danish women and men. Describing the burden of anal cancer and AIN may be valuable in future evaluations of the human papillomavirus (HPV) vaccine. We included all......-associated histological types levelled out or even declined during the 30 years of observation. In women, the increase in HPV-associated cancers was more pronounced among those under 60 years of age. Our findings indicate that vaccines against HPV might play an important role in the prevention of anal cancer and its...... cases of AIN2/3 during the study period. The average annual percentage change of 5% between 1998 and 2008 represents a steep increase in the incidence of AIN in both genders. Furthermore, the incidence rate of HPV-associated anal cancers increased significantly, whereas that of non-HPV...

    2012-02-01

    BACKGROUND: Anal intraepithelial neoplasia (AIN) rarely receives as much publicity as its neighbouring orifice, the cervix. As in the cervix, intraepithelial neoplasias are precursors to cancer in the anal canal. AIN and cervical interstitial neoplasia (CIN) undergo dysplasia as a consequence of human papillomavirus (HPV) infection. Since the advent of screening with the Pap smear in CIN, cervical cancer has plummeted to a fifth of its initial incidence. Anal cancer, however, has been rising, with a predilection for human immunodeficiency virus-infected men. HPV causes a squamous epithelial dysplasia and converts healthy tissue into AINs of increasing severity until anal cancer manifests. CLINICAL CASE: This article describes a clinical case of anogenital HPV infection refractory to medical and surgical therapy. It also describes an effective surgical excision technique associated with a good cosmetic outcome. CONCLUSIONS: The paper concludes by briefly discussing the implications of a national screening programme against AIN in the future.

    Full Text Available Incidence of anal cancer is increasing and risk of anal cancer is higher in MSM, especially if they are HIV+. European guidelines for treatment of HIV-infected adults recommend anal cancer screening by digital rectal exam±Pap test with anuscopy if Pap test is abnormal. A systematic anal cancer screening in HIV+MSM with anal cytology (Pap smears was established in June 2011 in our reference centre in Brussels. If anal cytology was abnormal, high-resolution anuscopy (HRA with biopsy was performed. 353 MSM HIV+were screened by anal smears between June 2011 and May 2012. 90% were Caucasians, median age was 44.5 years, 83% were on HAART and 74% had an undetectable viral load, median CD4 was 632/µl and 33% had a nadir CD4<200. Thirty-three (9.3% were excluded because of poor quality. Cytology was abnormal in 46% of the 320 remaining patients: high-grade squamous intraepithelial lesion (HSIL 3%, low-grade squamous intraepithelial lesion (LSIL 24%, atypical squamous cells of undetermined significance (ASC-US 16%, and atypical squamous cells / cannot rule out a high-grade lesion (ASC-H 3%. Viral load (VL was more frequently undetectable (82% vs 64%, p=0.0003 and median duration of HAART was longer (111 vs 61 months, p=0.0145 in patients with normal cytology. 80 HRA with biopsies have been performed. 12.5% were normal, 44% showed anal intraepithelial neoplasia (AIN 1, 24% AIN 2 and 19% AIN 3. For this analysis, high-grade AIN (2 and 3 were put together (AIN 2+. Among patients with AIN 2+(n=33, cytology had showed 8 (24% ASC-US, 3 (9% ASC-H, 19 (57% LSIL, 3 (9% HSIL. When patients with normal cytology or normal biopsy and patients with AIN 2+were compared, the only significant risk factor found for AIN 2+was a nadir CD4<100/µl (32% of the patients with AIN 2+vs 14% in patients with normal smear, p=0.0073. Anal precancerous lesions are frequent and at different stages. Among 46% abnormal cytology, 87% had abnormal biopsy including half AIN 2+.Cytology

    Acute interstitial nephritis (AIN) is a common cause of acute kidney injury and is characterised by a dense interstitial cellular infiltrate, which has not been well defined. Previous studies have demonstrated a correlation between Epstein-Barr virus (EBV) infection and AIN. The purpose of our study was to define the nature of the interstitial immune infiltrate and to investigate the possibility of renal infection with EBV.

    2015-01-01

    Full Text Available Acute interstitial nephritis (AIN is characterized by inflammation of the renal interstitium and usually occurs in a temporal relationship with the medication. We present a case of an Asian male who had nephrotic range proteinuria and presented with acute kidney injury. The patient reported an acute change in physical appearance and symptomatology after the ingestion of a single dose of sildenafil. Renal biopsy was notable for minimal change disease (MCD with acute and chronic interstitial nephritis. Renal replacement and glucocorticoid therapy were initiated. Renal recovery within six weeks permitted discontinuation of dialysis. AIN superimposed on MCD is a known association of NSAID induced nephropathy. The temporal association and the absence of any new drugs suggest that the AIN was most likely due to the sildenafil. NSAIDs are less likely to have caused the AIN given their remote use. The ease of steroid responsiveness would also suggest another cause as NSAID induced AIN is often steroid resistant. The MCD was most likely idiopathic given the lack of temporal association with a secondary cause. As the number of sildenafil prescriptions increases, more cases of AIN may be identified and physician awareness for this potential drug disease association is necessary.

  4. Acute interstitial nephritis with acetaminophen and alcohol intoxication

    2011-04-01

    Full Text Available Abstract Drug-induced acute interstitial nephritis (AIN represents a growing cause of renal failure in current medical practice. While antimicrobials and non-steroidal anti-inflammatory drugs are typically associated with drug-induced AIN, few reports have been made on the involvement of other analgesics. We report our experience in managing a 17-year-old female with AIN and subsequent renal injury following an acetaminophen overdose in conjunction with acute alcohol intoxication. It is well established that acetaminophen metabolism, particularly at high doses, produces reactive metabolites that may induce renal and hepatic toxicity. It is also plausible however, that such reactive species could instead alter renal peptide immunogenicity, thereby inducing AIN. In the following report, we review a possible mechanism for the acetaminophen-induced AIN observed in our patient and also discuss the potential involvement of acute alcohol ingestion in disease onset. The objective of our report is to increase awareness of healthcare professionals to the potential involvement of these commonly used agents in AIN pathogenesis.

    Diet is an important variable in toxicology. There are mixed reports on the impact of soy components on energy utilization, fat deposition, and reproductive parameters. Three generations of CD-1 mice were fed irradiated natural ingredient diets with varying levels of soy (NIH-41, 5K96, or 5008/5001), purified irradiated AIN-93 diet, or the AIN-93 formulation modified with ethanol-washed soy protein concentrate (SPC) or SPC with isoflavones (SPC-IF). NIH-41 was the control for pairwise comparisons. Minimal differences were observed among natural ingredient diet groups. F0 males fed AIN-93, SPC, and SPC-IF diets had elevated glucose levels and lower insulin levels compared with the NIH-41 group. In both sexes of the F1 and F2 generations, the SPC and SPC-IF groups had lower body weight gains than the NIH-41 controls and the AIN-93 group had an increased percent body fat at postnatal day 21. AIN-93 F1 pups had higher baseline glucose than NIH-41 controls, but diet did not significantly affect breeding performance or responses to glucose or uterotrophic challenges. Reduced testes weight and sperm in the AIN-93 group may be related to low thiamine levels. Our observations underline the importance of careful selection, manufacturing procedures, and nutritional characterization of diets used in toxicological studies. PMID:27234134

    Nitriding of surface of aluminum alloys was carried out with using an electron-beam-excited-plasma (EBEP)technique. The EBEP is sustained by electron impact ionization with energetic electron beam. Two kinds of substrates,aluminum alloys AA5052 and AA5083, were exposed to the down flow of EBEP source at 843 K for 45min. The specimens were characterized with respect to following properties: crystallographic structure (XRD), morphology (SEM) and the cross sectional microstructures of the nitrided layer was observed using a scanning electron microscopy (SEM). There are some Al2O3 particles on the surface of the nitrided AA5052 and AA5083. The AIN layers were formed on the substrates with the thickness of 4.5 μ m for AA5052 and 0.5 μ m for AA5083. A relatively uniform nitrided surface layer composed of AIN can be observed on the AA5052 substrate. The grains size near the interfaces between the substrate and AIN layer were smaller than that near the surface. On the surface of AIN layer, the concentration of nitrogen was high and in the middle of AIN layer it had a constant concentration like the aluminum and the concentration was decreased with approaching to the interface. On the surface of nitrided AA5083, a uniform AIN layer was not formed as the reason for the high nitriding temperature.

    Research Highlights: Human papillomaviruses cause anal intraepithelial neoplasia (AIN). Digital image processing was carried out to classify the grades of AIN quantitatively. The fractal dimension as well as grey value statistics was calculated. Higher grades of AIN yielded higher values of the fractal dimension. An automatic detection system is feasible. - Abstract: It is well known that human papillomaviruses (HPV) induce a variety of tumorous lesions of the skin. HPV-subtypes also cause premalignant lesions which are termed anal intraepithelial neoplasia (AIN). The clinical classification of AIN is of growing interest in clinical practice, due to increasing HPV infection rates throughout human population. The common classification approach is based on subjective inspections of histological slices of anal tissues with all the drawbacks of depending on the status and individual variances of the trained pathologists. Therefore, a nonlinear quantitative classification method including the calculation of the fractal dimension and first order as well as second order image statistical parameters was developed. The absolute values of these quantitative parameters reflected the distinct grades of AIN very well. The quantitative approach has the potential to decrease classification errors significantly and it could be used as a widely applied screening technique.

At the optimum operating conditions, the yield of supercritical extraction is similar to the conventional extraction by organic solvent, but the quality of the wheat germ oil extracted by supercritical carbon dioxide is higher. Furthermore, supercritical extraction could be more economical than organic extraction because the solvent removal by distillation is not necessary and several steps of the following oil refining process can be simplified.

    En el presente trabajo se realiza un estudio de la calidad del aceite de germen de trigo obtenido mediante la extracción con dióxido de carbono a alta presión.

    Full Text Available En estos últimos años, principalmente en los Estados Unidos, ha surgido una gran variedad de equipos portátiles para el examen rápido de suelos, basados la mayor parte en reacciones calorimétricas para fósforo, potasio, nitratos y algunos otros elementos considerados de importancia para la vida de la planta. El factor que determina la gran variedad de resultados obtenidos con tales equipos es la naturaleza del disolvente empleado para extraer los elementos de la muestra de suelo, disolvente que consiste, por lo general en soluciones de distinta concentración de ácido clorhídrico, sulfúrico, acético. etc. Si se admite que estos exámenes rápidos en el campo pueden ser útiles en países donde los agricultores cuentan con grandes facilidades para hacer verificar análisis completes de sus tierras, con mayor razón debemos admitir que en nuestro país, donde no abundan los laboratorios especializados, los equipos portátiles son casi una necesidad para la orientación de los agrónomos oficiales que operan en regiones apartadas. Debido a esto, la Facultad Nacional de Agronomía se ha interesado en el desarrollo de un equipo portátil lo más compacto posible para el uso de los agrónomos.

    2002-06-01

    Full Text Available The olive foot cake is a very important by-product of olive oil industry since it can contain until 12 % of oil which can be extracted using solvent. The used solvent is often immiscible with water. This is the reason why its effect is limited by the moisture of olive foot cake making its drying imperative. In this paper, we present the behaviour of olive foot cake subjected to convective drying. The experimental results show that the drying rate versus moisture presents only one period of decreasing rate. The influence of the main parameters on drying kinetics is studied.El orujo es un importante subproducto de la industria del aceite de oliva ya que puede contener hasta el 12 % del aceite, el cual puede ser extraído usando un disolvente apropiado. El uso del disolvente es a menudo inmiscible con el agua. Esta es la razón por la que su efecto está limitado por la humedad del orujo, haciendo su secado imperativo. En este artículo se presenta el comportamiento del orujo sometido a un secado por convección. Los resultados experimentales mostraron que la velocidad de secado frente a la humedad, presenta un solo período de disminución de dicha velocidad. Se ha estudiado la influencia de los principales parámetros sobre la cinética de secado.

    Hybrid Capture 2 (HC2) Human Papillomavirus (HPV) DNA Test® is FDA approved and is a proven aid in detecting HPV infections of the cervix and as an aid in diagnosing, with cytology, cervical disease. A prospective feasibility study was conducted to determine if HC2 testing has utility when screening for high-grade anal dysplasia (AIN2+). We enrolled 298 patients (45% HIV+) who had AIN2+ screening with cytology, histology and HC2 testing for two specimens: a swab into liquid-based cytology medium and either a swab or a brush collection in specimen transport medium (STM). High-resolution anoscopy was performed on all patients with biopsy of AIN2+ suspicious lesions. Cytology was benign (42%), atypical squamous cells of undetermined significance (30%), low-grade squamous intraepithelial lesion (18%), high-grade squamous intraepithelial lesion (1%), ASCUS possibly high-grade dysplasia (1.7%) and nondiagnostic (7%) and 36% had AIN2+ histology. Sensitivity and specificity for predicting AIN2+ histology for any abnormal cytology were 77 and 52%, whereas HC2 sensitivity and specificity were 91 and 40% (p = 0.005 for sensitivity), respectively. There was no significant difference in HC2 sensitivity or specificity between brush and swab or STM and residual cells from cytology. AIN2+ was found in 20% of patients with benign cytology. Only nine AIN2+ specimens were HC2-. This prospective study indicates that HC2 may be useful when screening for anal dysplasia; however, a larger study is recommended. PMID:22234750

    Autoimmune neutropenia (AIN) in infancy is caused by antineutrophil (granulocyte-specific) autoantibodies. These antibodies are rarely found in circulation because their serum levels are extremely low. We hypothesized that a direct granulocyte immunofluorescence test (D-GIFT) that enables us to detect neutrophil-bound autoantibodies consisting of both immunoglobulin (Ig) G and IgM has better diagnostic value than the detection of circulating autoantibodies. Whole blood (100 μL) was obtained from 50 infants with AIN, 12 infants with transient neutropenia, and 37 control infants. D-GIFT was performed using both fluorescein isothiocyanate-conjugated antihuman IgG Fc portion monoclonal antibodies and fluorescein isothiocyanate antihuman IgM monoclonal antibodies. Results were assessed as relative fluorescence intensity (RFI). The RFIs of antineutrophil IgG-bound and antineutrophil IgM-bound cells in patients with AIN were significantly higher than those in patients with transient neutropenia and in controls. Positive results, as assessed by RFI scores of more than 1.81 in either antineutrophil IgG-bound or antineutrophil IgM-bound cells, showed the sensitivity and specificity of D-GIFT, and the areas under the receiver operating characteristic curve (0.98, 0.98, and 0.997, respectively) in the diagnosis of AIN. D-GIFT detecting both neutrophil-bound IgG autoantibodies and IgM autoantibodies has discriminatory power for identifying patients with AIN and, therefore, can be a useful diagnostic test.

    Full Text Available This study aims to evaluate the effects of diets deficient in choline and/or cystine on hepatocellular injury in animal models (young male Wistar rats, aged 21 days, by monitoring some of the oxidative stress biomarkers and the expression of RAGE, TNF-α, and IL-1β. The animals were divided into 6 groups (n=10 and submitted to different diets over 30 days: AIN-93 diet (standard, St, AIN-93 choline deficient (CD diet and AIN-93 choline and cystine deficient (CCD diet, in the pellet (pl and powder (pw diet forms. Independently of the diet form, AIN-93 diet already led to hepatic steatosis and CD/CCD diets provoked hepatic damage. The increase of lipid peroxidation, represented by the evaluation of thiobarbituric acid reactive species, associated with the decrease of levels of antioxidant enzymes, were the parameters with higher significance toward redox profile in this model of hepatic injury. Regarding inflammation, in relation to TNF-α, higher levels were evidenced in CD(pl, while, for IL-1β, no significant alteration was detected. RAGE expression was practically the same in all groups, with exception of CCD(pw versus CCD(pl. These results together confirm that AIN-93 causes hepatic steatosis and choline and/or cysteine deficiencies produce important hepatic injury associated with oxidative stress and inflammatory profiles.

    Full Text Available Acute renal failure following vasculotoxic viperine snake bites is very common in South Asia. Acute tubular necrosis and acute cortical necrosis are the common findings, with acute interstitial nephritis (AIN being a rare presentation. We conducted renal biopsies in all patients who were admitted in our institute with viperine snake bite-related acute kidney injury (AKI and who did not improve after three weeks of supportive care. Patients who had findings of AIN on renal histology were included for this study. Of a total of 42 patients, there were five patients (11.9% with AIN. Our series of five patients is the largest series of this rare presentation in the literature. All of these five patients had features of severe envenomation, severe AKI network stage of AKI and very high antivenom requirements. They had a very prolonged stay in the hospital, and four of the five patients developed chronic kidney disease on follow-up. The overall outcome in this group was worse as compared with those who did not have AIN. AIN following viperine snake bites is not a very rare presentation. The reason for the development of this pathology is unclear, but direct venom-related effects are possible. This presentation portends a poor overall long-term prognosis as demonstrated in our case series.

Commercial hexane and petroleum ether were used as solvents and the extraction was carried out at temperatures ranging from 30 to 55 °C using solvent-to-solid ratios, R between 2 and 15 L/kg. The equilibrium compositions of the solvent and solid phases were determined. Based on the equilibrium data, the partition coefficient or distribution ratio, D of the oil between both phases was estimated. Also, the number of extraction stages necessary to achieve a certain degree of oil recovery has been determined using different hexane-to-meal ratios. Jojoba oil was also tested for its physical and chemical properties including chemical composition, percentage fatty acid, peroxide value, flash point, fire point, pour point, refractive index, saponification and iodine values. The stability of jojoba oil during storage at room temperature and during heat treatment was also studied.Se ha estudiado el proceso de extracción con disolventes del aceite contenido en la harina residual del prensado mecánico de las semillas de jojoba.

    Introduccion. La arquitectura interna del hematoma subdural cronico (HSDC) es un factor muy importante que se debe tener en cuenta como predictor de recidiva. Objetivo. Analizar los factores posiblemente asociados a la recidiva de los HSDC, prestando especial atencion a dicha arquitectura. Pacientes y metodos. Hemos revisado 147 pacientes tratados desde 2010 hasta 2013. Dividimos los HSDC en cuatro tipos de acuerdo con la clasificacion de Nakaguchi de 2001. Ademas, hemos recogido diferentes caracteristicas clinicas y las hemos sometido a analisis estadistico para evaluar su posible asociacion con la tasa de recidiva de los HSDC. Resultados. La tasa de recidiva fue del 14,75% y la de mortalidad, del 4,76%. El tratamiento con anticoagulantes, el tipo de hematoma y el no usar drenaje subdural fueron factores de riesgo estadisticamente significativos para la recurrencia del HSDC. Segun la arquitectura interna, la tasa de recidiva fue del 36,36% para el tipo separado, del 15,90% para el laminar, del 8,82% para el homogeneo y del 0% para el trabecular. Dicha tasa fue significativamente mayor en el tipo separado respecto al homogeneo y trabecular. Conclusiones. El tratamiento con anticoagulantes y el no usar drenaje subdural son factores de riesgo de recurrencia de HSDC. Ademas, la division de los HSDC de acuerdo con la clasificacion de Nakaguchi puede ser util para predecir el riesgo de recurrencia, ya que la tasa de recidiva del tipo separado fue significativamente mayor que la del resto de tipos.

    Electrical properties of AlyGa1-yN/AlxGa1-xN/AIN/GaN structure are investigated by solving coupled Schrodinger and Poisson equation self-consistently. Our calculations show that the two-dimensional electron gas (2DEG) den-sity will decrease with the thickness of the second barrier (AlyGa1-yN) once the AIN content of the second barrier is smaller than a critical value yc, and will increase with the thickness of the second barrier (AlyGa1-yN) when the critical AIN content of the second barrier yc is exceeded. Our calculations also show that the critical AlN content of the second barrier yc will increase with the AlN content and the thickness of the first barrier layer (AlxGa1-xN).

    Full Text Available Acute interstitial nephritis (AIN is a common cause of acute kidney injury and has been associated with a variety of medications. This is the case of 30-year-old man with Hodgkin’s lymphoma who on routine labs before chemotherapy was found to have acute nonoliguric renal failure. A kidney biopsy was performed and confirmed the diagnosis of acute interstitial nephritis. The patient had taken several medications including a higher dose of Carnivora, a Venus flytrap extract, composed of numerous amino acids. The medication was discontinued and kidney function improved towards the patient’s baseline indicating that this may be the possible cause of his AIN. Proximal tubular cell uptake of amino acids increasing transcription of nuclear factor-kappaB is a proposed mechanism of AIN from this compound.

    The incidence of anal squamous cell carcinoma has increased alarmingly, particularly in high-risk groups such as men who have sex with men and immunosuppressed patients. Infection with an oncogenic strain of the human papillomavirus in the anal canal or perianal skin leads to anal intraepithelial neoplasias (AIN), progressive dysplastic intraepithelial lesions that are the precursors of anal squamous cell carcinoma. AIN can be diagnosed through cytological screening and biopsy guided by high-resolution anoscopy and can be treated using a range of procedures in an effort to prevent progression to invasive anal carcinoma. Given the recent advances in the understanding of this disease, and the increasing calls from experts for the establishment of screening programs to identify AIN, we review current knowledge on the condition, its diagnosis, and treatment from the point of view of dermatology.
