    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.

  8. Terapia anticoagulante en fibrilación auricular

    Directory of Open Access Journals (Sweden)

    2011-06-01

    Full Text Available La fibrilación auricular es la taquiarritmia cardíaca más frecuente. Su incidencia aumenta con la edad, presentándose en un 1.5% entre los 50 a 59 años, y en un 8-10% entre los 80 a 89 años. Esta arritmia incrementa en cinco veces el riesgo de sufrir un evento cerebrovascular isquémico cardioembólico y causa el 15% de todos los accidentes cerebrovasculares isquémicos. Su manejo se enfoca en la prevención de los fenómenos tromboembólicos y el control de la frecuencia y ritmo cardíaco. El tratamiento anticoagulante ha demostrado ser la principal herramienta en la prevención de eventos cardioembólicos. Aunque las complicaciones hemorrágicas por el tratamiento son esperables y aumentan con la edad, el beneficio de usar anticoagulación sobrepasa por mucho al riesgo de sangrado. Precisamente debido a la heterogeneidad clínica de esta arritmia y a la dificultad de establecer un tratamiento adecuado para cada caso en particular, el American College of Cardiology, la American Heart Association, la European Society of Cardiology y el American College of Chest Physicians han establecido guías para mejorar el tratamiento de estos pacientes. La revisión de esta enfermedad y de las directrices propuestas puede facilitar y mejorar notablemente el tratamiento de los pacientes con fibrilación auricular.

    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.

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.

    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.

    Full Text Available Eventos tromboembólicos são complicações comuns em pacientes críticos. 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.

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. Una técnica que permite recuperar el cromo existente en estas sustancias es la extracción con disolventes orgánicos. En el presente trabajo se estudia la extracción del Cr(III presente en disoluciones acuosas con disoluciones de un reactivo de carácter catiónico (DEHPA en queroseno. Igualmente se estudia el proceso de reextracción. Se ha encontrado que el Cr(III y el DEHPA reaccionan mol a mol, siendo la cinética de extracción muy rápida. El pH final de

    Full Text Available La fibrilación auricular es la taquiarritmia cardíaca más frecuente. Su incidencia aumenta con la edad, presentándose en un 1.5% entre los 50 a 59 años, y en un 8-10% entre los 80 a 89 años. Esta arritmia incrementa en cinco veces el riesgo de sufrir un evento cerebrovascular isquémico cardioembólico y causa el 15% de todos los accidentes cerebrovasculares isquémicos. Su manejo se enfoca en la prevención de los fenómenos tromboembólicos y el control de la frecuencia y ritmo cardíaco. El tratamiento anticoagulante ha demostrado ser la principal herramienta en la prevención de eventos cardioembólicos. Aunque las complicaciones hemorrágicas por el tratamiento son esperables y aumentan con la edad, el beneficio de usar anticoagulación sobrepasa por mucho al riesgo de sangrado. Precisamente debido a la heterogeneidad clínica de esta arritmia y a la dificultad de establecer un tratamiento adecuado para cada caso en particular, el American College of Cardiology, la American Heart Association, la European Society of Cardiology y el American College of Chest Physicians han establecido guías para mejorar el tratamiento de estos pacientes. La revisión de esta enfermedad y de las directrices propuestas puede facilitar y mejorar notablemente el tratamiento de los pacientes con fibrilación auricular.Atrial fibrillation is the most frequent cardiac arrhythmia in adults. Its frequency increases with age, being its incidence 1.5% in individuals 50 to 59 years old and 8-10% from 80 to 89 years. Atrial fibrillation increases 5 fold the risk of suffering stroke and actually causes 15% of all strokes. Its management focuses primary in the prevention of thromboembolic phenomena, heart rate and rhythm control. Anticoagulation, when indicated, has demonstrated to be the main tool in the prevention of these thromboembolic events. Although the bleeding complication is frequent in this population and increases with age, anticoagulation benefits are

    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.

    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.

    Bacterial quorum sensing using acyl-homoserine lactones (acyl-HSLs) as cell-density dependent signalling molecules is important for the transcriptional regulation of many genes essential in the establishment and the maintenance of bacteria-host associations. Vibrio fischeri, the symbiotic partner of the Hawaiian bobtail squid Euprymna scolopes, possesses two distinct acyl-HSL synthase proteins, LuxI and AinS. Whereas the cell density-dependent regulation of luminescence by the LuxI-produced signal is a well-described phenomenon, and its role in light organ symbiosis has been defined, little is known about the ain system. We have investigated the impact of the V. fischeri acyl-HSL synthase AinS on both luminescence and symbiotic colonization. Through phenotypic studies of V. fischeri mutants we have found that the AinS-signal is the predominant inducer of luminescence expression in culture, whereas the impact of the LuxI-signal is apparent only at the high cell densities occurring in symbiosis. Furthermore, our studies revealed that ainS regulates activities essential for successful colonization of E. scolopes, i.e. the V. fischeri ainS mutant failed to persist in the squid light organ. Mutational inactivation of the transcriptional regulator protein LuxO in the ainS mutant partially or completely reversed all the observed phenotypes, demonstrating that the AinS-signal regulates expression of downstream genes through the inactivation of LuxO. Taken together, our results suggest that the two quorum-sensing systems in V. fischeri, ain and lux, sequentially induce the expression of luminescence genes and possibly other colonization factors.

    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

En la literatura se describen dos enfoques terapéuticos en casos de intervenciones quirúrgicas en esta categoría de pacientes. Uno propone la reducción de la dosis terapéutica del fármaco, mientras que el segundo sugiere la sustitución con heparina. El objetivo de este trabajo es revisar la literatura que trata este tema con el fin de obtener un protocolo ideal. Conclusiones. En caso de extracciones simples es suficiente usar anestesia con vasoconstrictor (en el caso de que no haya otras contraindicaciones, realizar suturas bien tensadas, aplicar coadyuvantes hemostáticos locales y ácido tranexámico tópico. Solo en casos de intervenciones más complejas, o con valores de INR mayores a 3,5, será necesario reducir la dosis del fármaco y consecuente sustitución con heparina de acuerdo a las instrucciones del hematólogo y del cardiólogo.Aim of the work. In patients treated with oral anticoagulants, even simple tooth extractions can produce large hemorrhages. There are two main therapeutic outlines suggested in literature in case of little oral surgery. The first one is based on the reduction of the therapeutic dose of the drug, and the second one on the substitution with heparin. The aim of this paper was to review the.literature on the management of patients treated with anticoagulants in order to obtain univocal guidelines. Conclusion. In case of simple tooth extractions generally a vasoconstrictive anaesthetic (if there are no other contraindications, tight sutures, the application of hemostats and tronexamic acid are enough. Only in case of more complex surgery or of INR values higher than 3,5 it is necessory to reduce the anticoagulant dose or to change the therapy with heparin, if agreed by the hoemotologist and/ or the cardiologist.

Method: This is a cross sectional observational study of patients attending ambulatory healthcare centers in Al Ain, United Arab Emirates in 2009. From a yearly audit evaluating the care of patients with diabetes and hypertension, the determinants for improved diabetes and hypertension outcomes were identified from a total of 512 patients and its association with glycemic and blood pressure control were studied. Results: From all variables studied, only the clinic where the patient was treated helped predict both improved blood sugar and blood pressure control. For patients with diabetes, poor control the year before (p<0.001, the number of chronic disease clinic visits (p=0.042 and triglyceride levels (p=0.007 predicted worse control of diabetes. A predictor of poor control of blood pressure (p<0.001 for patients with hypertension was poor control of blood pressure in the year before. Conclusion: In this population, the healthcare system and the team played major roles as determinants in the control of patient’s diabetes and blood pressure more than any of the other factors examined.

    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.

    Introducción: En la investigación científica, hay varias dietas estándar para los animales, generalmente concebidas por instituciones científicas. 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.

    Egypt has a high incidence of neural tube defects. Folic acid supplementation in the periconceptional period is known to lower the risk of such defects. This cross-sectional study aimed to measure the level of knowledge about periconceptional folic acid use among pregnant women attending for antenatal care at Ain Shams University Hospital, Cairo, Egypt in 2012. 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.

    Full Text Available Algeria does not escape the problem of the climate change, its geographical position in zone of transition, and its dry and semi-arid climate, in fact a very vulnerable space. In Algeria, approximately two thirds of the population is concentrated on the coast which represents only 4 % of the territory. The Mediterranean coast, in particular in Algeria, is subjected to pressures: financial stakes, climatic risks, pollutions and conservation of the water. It is on the basis of the critical and objective report with regard to a wild urbanization of the Algerian coast as well as the influence of the demographic pressure that the choice of the search for this article was held. This publication has for objective to raise (to draw up a current situation (inventory of fixtures of the sector of the environment in Algeria and to present through the case of the coastal city of Oran the consequences of climate change. We propose, to review the situation through the case of the municipality of Ain El Türck, by basing itself on data relative to the evolution of the temperatures and the sea level.

    Floodplain development is associated with lateral accretion along stable channel geometry. Along shifting rivers, the floodplain sedimentation is more complex because of changes in channel position but also cutoff channel presence, which exhibit specific overflow patterns. In this contribution, the spatial and temporal variability of sedimentation rates in cutoff channel infill deposits is related to channel changes of a shifting gravel bed river (Ain River, France). The sedimentation rates estimated from dendrogeomorphic analysis are compared between and within 14 cutoff channel infills. Detailed analyses along a single channel infill are performed to assess changes in the sedimentation rates through time by analyzing activity profiles of the fallout radionuclides 137Cs and unsupported 210Pb. Sedimentation rates are also compared within the channel infills with rates in other plots located in the adjacent floodplain. Sedimentation rates range between 0.65 and 2.4 cm a -1 over a period of 10 to 40 years. The data provide additional information on the role of distance from the bank, overbank flow frequency, and channel geometry in controlling the sedimentation rate. Channel infills, lower than adjacent floodplains, exhibit higher sedimentation rates and convey overbank sediment farther away within the floodplain. Additionally, channel degradation, aggradation, and bank erosion, which reduce or increase the distance between the main channel and the cutoff channel aquatic zone, affect local overbank flow magnitude and frequency and therefore sedimentation rates, thereby creating a complex mosaic of sedimentation zones within the floodplain and along the cutoff channel infills. Last, the dendrogeomorphic and 137Cs approaches are cross validated for estimating the sedimentation rate within a channel infill. Copyright 2008 by the American Geophysical Union.

    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 BACKGROUND: Road traffic injuries (RTIs constitute 45% of injury mortality in Egypt; 75% of these injuries are pedestrians related. Traditionally, research on road traffic safety has focused on the traffic environment and the vehicles. However, little attention has been given to road risky behaviors and perceptions of road safety by pedestrians as risk factors associated with high pedestrian injury rates. This study aimed to examine the relationship between road risk- perception, specific road behaviors, and self-reported pedestrian injuries among university students in Cairo, Egypt. METHODS: A cross sectional survey was conducted among university students aged 18 to 24 years old at Ain Shams University in Cairo. Questions covered socio-demographic variables, injury episodes, road behaviors, road risk-perceptions, attitudes towards injury prevention, and road safety education. RESULTS: The survey was completed by 1,324 students. Two hundred ninety (21.9% of the participants suffered from pedestrian injury during the past 6 months; of these, 28.9% were admitted to hospital or clinic as a result of the injury, 39.3% were unable to go to university or leave home because of the injury for a period ranging from one day up to one week. Participants were more likely to suffer from pedestrian injury when they did not always "look both ways to cross the road", whereas always “waiting for a green light” was protective. Students who "perceived it safe to cross the road from any point" or "did not perceive it to be safer to cross at a zebra crossing" were less likely to "look both ways" before crossing the road. Similarly, there was a positive association between road safety education and participants’ road crossing behaviors. CONCLUSION: Inappropriate youths' road behaviors were significantly associated with pedestrian injury. There was also a positive association between road risk perception and road behaviors. This suggests that a behavioral

    In the last decade, considerable research effort was directed to the deposition of multilayer films with layer thicknesses in the nanometer range (superlattice coatings), in order to increase the performance of various cutting tools and machine parts. The goal of the present work was to investigate the main microstructural, mechanical and wear resistance characteristics of a superlattice coating, consisting of alternate multilayer ZrN/TiAIN films, with various bilayer periods (5 / 20 nm). The coatings were deposited by the cathodic arc method on Si, plain carbon steel and high speed steel substrates to be used as wear resistance surfaces. The multilayer structures were prepared by using shutters placed in front of each cathode (Zr and Ti+Al). The characteristics of multilayer structures (elemental and phase composition, texture, Vickers microhardness, thickness, adhesion, and wear resistance) were determined by using various techniques (AES, XPS, XRD, microhardness measurements, scratch, and tribological tests). A comparison with the properties of ZrN and TiAIN single-layer coatings was carried out.

    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.

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.

    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.

    The requirements of low cost and high-tempurature corrosion resistance for bipolar interconnect plates in solid oxide fuel cell stacks has directed attention to the use of metal plates with oxidation resistant coatings. We have investigatedt he performance of steel plates with multilayer coatings consisting of CrN for electrical conductivity and CrAIN for oxidation resistance. The coatings were deposited usin large area filterd arc deposition technolgy, and subsequently annealed in air for up to 25 hours at 800 degrees celsius. The composition, structer and morphology of the coated plates were characterized using RBS, nuclear reaction analysis, AFM and TEM techniques. By altering the architecture of the layers within the coatings, the rate of oxidation was reduced by more than an order of magnitute. Electrical resistance was measured at room temperature.

    'Ain Ghazal is among the earliest large population centers known in the Middle East. A total of four major stratigraphic cultural units have been identified: 1) The oldest Middle Pre-Pottery Neolithic B (MPPNB) unit (10.2 to 9.5 cal ka BP) clearly corresponds with the early Holocene maximum Dead Sea levels. 2) The second unit consists of Late Pre-Pottery Neolithic B (LPPNB) in situ walls and hearths. 3) In the subsequent PPNC (8.9 to 8.6 cal ka BP) the population density at the settlement drops dramatically, which corresponds with a significant drop in the Dead Sea level. 4) The 4th stratigraphic unit is characterized by the "Yarmoukian rubble layer". Additionally, there is evidence for a previously unrecognized use of the site by Chalcolithic pastoralists. Sedimentological analyses reveal a constant increase in dust from a remote source during the entire human occupation period, which correlates well with the detectable drops in climatic humidity from the Dead Sea. As the major focus of this study, we can now rule out previous notions that the "Yarmoukian" rubble layer could have been produced by (catastrophic) slope-scale gravitational movements. To this point, it appears that the Neolithic mega-site was abandoned due to a climatic aridification.

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.

Foram avaliados 11 pacientes com diagnóstico positivo para DCG tipo I (três do gênero masculino e oito do gênero feminino, idade média de 5,6 anos; e oito pacientes com diagnóstico negativo para DCG(quatro do gênero masculino e quatro do gênero feminino, idade média de 4,5 anos (grupo-controle. O diagnóstico de DCG tipo I foi realizado pela identificação do padrão de hipoglicosilação da transferrina plasmática. Na avaliação dos anticoagulantes naturais pode-se observar redução dos valores de PS livre e PC e uma redução marcante de AT, quando comparados com o grupo controle. Em relação aos fatores de coagulação não houve diferença significativa para os fatores VIII e IX e houve redução marcante do fator XI. Os resultados do presente estudo sugerem que a deficiência combinada de anticoagulantes naturais é responsável pelo estado pró-trombótico observado em pacientes com DCG.

    2016-04-01

    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 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.

    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.

    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

Characterization studies at the La Ronde tailings mine (Agnico-Eagle Ltd, in Abitibi), showed quite encouraging results (Campos, 2004; Anterrieu, 2006). Since it is a salt-bearing areas (highly conductive) and given that the induced polarization is very sensitive to the ground conductivity; by measurement of residual potential, so we took measures chargeability tomography, the result is compared to the resistivity measured at different soils (control and irrigated), which will better clarify the impact of salinity on the quality of the disturbed soil. Indeed, the chargeability response it possible to characterize the different irrigated soils and its variation is attributed not only to the effect of saline irrigation but also the existence of an heterogeneity of the original ground. Prospecting in electrical tomography has displayed vertically and horizontally anomalies existing within the experimental site of the station of Ain Al Atti, it showed that: - accumulation of salinity becomes wider going from the control ground to that of Acacias. - surveyed the ground at least appear more homogeneous in surface, but their conductivity varies in depth. - salinity origin and the concretion formed on the surface greatly influenced chargeability and resistivity measured on the different experimental soils.

    Full Text Available Au Maroc, l’utilisation des eaux souterraines pour l’irrigation a permis un développement agricole rapide dans de nombreuses régions, mais a aussi fait émerger des situations de baisse des niveaux piezométriques des nappes qui menacent la durabilité de cette agriculture irriguée. L’article présente une action de recherche portant sur la conception d’un projet de territoire agricole durable alliant développement agricole et usage pérenne des ressources en eau souterraine. L’étude a eu lieu dans la zone d’Ain Timguenay (province de Séfrou, qui connait un fort développement de la production de pommes et de prunes depuis une quinzaine d’années. Le programme de recherche a impliqué les agriculteurs, la commune rurale d’Ain Timguenay, les institutions du Ministère de l’Agriculture et l’Agence de bassin hydraulique du Sébou. Une analyse des dynamiques agricoles locales et des tendances nationales a servi de support aux discussions. L’étude de l’aquifère et de ses usages a permis d’établir un bilan sommaire et un ordre de grandeur des surfaces qui pourraient encore être plantées sans que les consommations en eau soient supérieures à la recharge de l’aquifère en année pluviométrique moyenne. Une réflexion prospective menée avec les agriculteurs a mis en évidence deux scénarios possibles à l’échelle locale: 1 un scénario où les difficultés économiques que rencontrent actuellement les exploitations de la zone se renforcent, conduisant à un ralentissement des nouvelles plantations, d’où une pression limitée sur la nappe ; 2 un scénario où les exploitations réussissent à faire face aux défis actuels de production et de commercialisation et de ce fait continuent à planter, ce qui conduit à une consommation en eau bien supérieure à la recharge de la nappe. L’ensemble des acteurs impliqués a participé à l’élaboration d’un troisième scénario permettant de concilier d

    The extraction of uranium on the trace level is studied by using tributylphosphate as active agent under conditions aiming the attainment of quantitative extraction by means of a single step process using a number of salting-out agents and keeping inside the general lines as reported in two precedent papers. Two inert solvents were investigated, benzene and cyclohexane, which allowed to derive the corresponding empirical equations describing the extraction process and the results obtained were compared with those previously reported for solvents which, like ethyl acetate and methylisobuthylketone, favour to a more or less extend the extraction of uranium.

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.

    @@ The Ⅲ-Ⅴ wide band gap semiconductors show the potential in applications for dilute magnetic semiconductors.AlN films are implanted with 20-keV Mn+ ions with a dose of 5 × 1016cm-2. The cross section of as-implanted AlN are investigated by field-emission scanning electron microscopy and the energy dispersive spectra. The result confirms that the implantation depth is about 100nm. Cathodoluminescence measurements show the main peak at 2.6eV attributed to a donor-to-Mn2+ transition. It is argued that the Mn element in AlN can act as a p-type dopant peak at 2.07eV. The magnetic measurement shows a transition temperature of 100K in the implanted AlN annealed at 500℃ for 30min. Clear ferromagnetic hysteresis was observed at 77K, with a coercive field of 212.7Oe.

    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.

  11. I-WARP: Individual Water mAin Renewal Planner

    Directory of Open Access Journals (Sweden)

    Y. Kleiner

    2010-05-01

    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.

    CERN Document Server

    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....

    1998-08-01

    Full Text Available The use of a neutral reactive (TBP and an alkalyne one (Primene 81R in order to carry out the extraction of chromium from aqueous solutions was studied. The following systems were tested: Cr(VI/TBP, Cr(III/Primene 81R, Cr(VI/Primene 81R. In the same way the stripping of both systems were studied. TBP can easily extract Cr(VI using pure TBP as organic phase and an aqueous phase with a concentration of sulphuric acid between 0.5 and 2 N. The kinetics of the process is very fast. NaOH solutions were used for stripping, reaching maximum yields with IN NaOH solutions. Primene 81R can extract not only Cr(III but also Cr(VI. Extraction of Cr(III must be made at values of pH around 6; this value has to be reached by addition of extraction agent. Extraction of Cr(VI must be made at values of pH between 3 and 5. Extraction kinetics of Cr(III and Cr(VI are both fast. In order to carry out the reextraction, NaOH solutions can be used. Cr(III is recovered as a chromium hydroxide precipitate if final pH is alkalyne; solutions of NaOH with a concentration equal or higher than 4N must be used for the stripping of Cr(VI, and the solution obtained contains chromium as Cr(III and Cr(VI.

    Se estudia el empleo de un reactivo de carácter neutro (TBP y otro de carácter básico (Primene 81R para llevar a cabo la extracción del cromo presente en disoluciones acuosas. Los sistemas investigados han sido el Cr(VI/TBP, el Cr(III/Primene 81R y el Cr(VI/Primene 81R. Asimismo, se abordan los procesos de reextracción en dichos sistemas. El TBP ha demostrado su capacidad para extraer el Cr(VI, debiendo estar constituida la fase orgánica por TBP puro y la fase acuosa poseer una concentración en ácido sulfúrico entre 0,5 y 2 N. La cinética del proceso es rápida. Se han empleado disoluciones de NaOH para proceder a la reextracción, alcanzándose el máximo rendimiento con disoluciones de NaOH 1N. El Primene 81R puede extraer tanto al Cr(III como al Cr(VI. La extracción del Cr(III se debe realizar a valores del pH próximos a 6, valor que se debe alcanzar por adición del agente de extracción. La extracción del Cr(VI se debe realizar a pH claramente ácido (3-5. Las cinéticas de extracción del Cr(III y del Cr(VI son rápidas. Para la reextracción se pueden emplear disoluciones de NaOH. En el caso del Cr(III, si el pH final es básico, se recupera un precipitado de hidróxido de cromo(III; para el Cr(VI se deben utilizar disoluciones de NaOH de concentración igual o mayor a 4 N, obteniéndose una disolución donde el cromo se encuentra en los estados de oxidación (III y (VI.

    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.

    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.

    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 pH3 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% iso decanol 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 NH{sub 4}OH 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.

    1995-06-01

    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.

    There is a dearth of local information in Al Amin, United Arab Emirates about antibiotic resistance patterns. In this retrospective study in a tertiary referral hospital, antibiotic susceptibility results were analysed over the 5-year period 2004-08 and compared with a previous study in the same hospital during 1999-2002. Staphylococcus aureus showed a significant decrease in sensitivity to oxacillin from 95.0% in the period 1999-2002 to 84.4% in 2008. Sensitivity of Acinetobacter spp. to imipenem dropped from 99.0% in 2004 to only 32.5% in 2008. During the same period, almost half of Escherichia coli isolates developed resistance to cefotoxime. Significant reductions in sensitivity to Pseudomonas aeruginosa between 1999 and 2008 were found for almost all the antibiotics tested. Klebsiella spp. did not show any significant change in resistance to any of the tested antibiotics. Serious efforts are needed to reduce the risk of the spread of resistant strains of bacteria.

    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

    Transport of proteins into or across biological membranes is catalyzed by membrane-bound transport machineries. In Gram-positive bacteria, the vast majority of proteins are exported out of the cytosol by the conserved general secretion (Sec) system or, alternatively, by the twin-arginine translocation (Tat) system, that closely resemble their well-studied counterparts in Gram-negative bacteria. Besides these common major export routes, additional unique protein export systems (such as accessory Sec2 systems and/or type VII/WXG100 secretion systems) exist in some Gram-positive bacteria that are specifically involved in the secretion of limited subsets of proteins.

    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.

  10. "Ain't no one here but us social forces": constructing the professional responsibility of engineers.

    Science.gov (United States)

    Davis, Michael

    2012-03-01

    There are many ways to avoid responsibility, for example, explaining what happens as the work of the gods, fate, society, or the system. For engineers, "technology" or "the organization" will serve this purpose quite well. We may distinguish at least nine (related) senses of "responsibility", the most important of which are: (a) responsibility-as-causation (the storm is responsible for flooding), (b) responsibility-as-liability (he is the person responsible and will have to pay), (c) responsibility-as-competency (he's a responsible person, that is, he's rational), (d) responsibility-as-office (he's the responsible person, that is, the person in charge), and (e) a responsibility-as-domain-of-tasks (these are her responsibilities, that is, the things she is supposed to do). For all but the causal sense of responsibility, responsibility may be taken (in a relatively straightforward sense)-and generally is. Why then would anyone want to claim that certain technologies make it impossible to attribute responsibility to engineers (or anyone else)? In this paper, I identify seven arguments for that claim and explain why each is fallacious. The most important are: (1) the argument from "many hands", (2) the argument from individual ignorance, and (3) the argument from blind forces. Each of these arguments makes the same fundamental mistake, the assumption that a certain factual situation, being fixed, settles responsibility, that is, that individuals, either individually or by some group decision, cannot take responsibility. I conclude by pointing out the sort of decisions (and consequences) engineers have explicitly taken responsibility for and why taking responsibility for them is rational, all things considered. There is no technological bar to such responsibility.

    2008-01-01

    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.

    2012-01-01

    We have conducted a statistical analysis of the ultra-luminous X-ray point sources (ULXs; L(X) >= 10^39 erg/s) in a sample of galaxies selected from the Arp Atlas of Peculiar Galaxies. We find a possible enhancement of a factor of ~2-4 in the number of ULXs per blue luminosity for the strongly interacting subset. Such an enhancement would be expected if ULX production is related to star formation, as interacting galaxies tend to have enhanced star formation rates on average. For most of the Arp galaxies in our sample, the total number of ULXs compared to the far-infrared luminosity is consistent with values found earlier for spiral galaxies. This suggests that for these galaxies, ULXs trace recent star formation. However, for the most infrared-luminous galaxies, we find a deficiency of ULXs compared to the infrared luminosity. For these very infrared-luminous galaxies, AGNs may contribute to powering the far-infrared; alternatively, ULXs may be highly obscured in the X-ray in these galaxies and therefore not ...

    Full Text Available OBJETIVO: Estudar prospectivamente a freqüência de complicações em pacientes tratados com warfarina e acompanhados no Ambulatório de Anticoagulação da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista. MÉTODOS: Pacientes sorteados entre os agendados para consulta de junho de 2002 a fevereiro de 2004. Na primeira consulta, foi preenchida ficha com dados de identificação e clínicos. A cada retorno, ou quando o paciente procurou o hospital por intercorrência, foi preenchida ficha com a razão normatizada internacional, existência e tipo de intercorrência e condições de uso dos antagonistas da vitamina K. RESULTADOS: Foram acompanhados 136 pacientes (61 homens e 75 mulheres, 99 com tromboembolismo venoso e 37 com doença arterial; 59 pacientes eram de Botucatu, e 77, de outros municípios. Foram registradas 30 intercorrências: nove não relacionadas ao uso da warfarina e 21 complicações hemorrágicas (38,8 por 100 pacientes/ano. Uma hematêmese foi considerada grave (1,9 por 100 pacientes/ano. As demais foram consideradas moderadas ou leves. Não houve óbitos, hemorragia intracraniana ou necrose cutânea. A única associação significante foi da freqüência de hemorragia com nível médio de razão normatizada internacional. CONCLUSÃO: Nossos resultados mostram a viabilidade desse tratamento em pacientes vasculares em nosso meio, mesmo em população de baixo nível socioeconômico, quando tratados em ambulatório especializado.OBJECTIVE: To prospectively study the frequency of complications in patients treated with warfarin followed at Botucatu Medical School. METHODS: Patients randomly selected among those with appointments scheduled from June 2002 to February 2004. At the first appointment, a protocol was filled with identification and clinical data. At every return or when the patient went to the hospital due to clinical events, another form was filled with the international normalized ratio, existence and type of clinical event and the conditions of use of vitamin K antagonists. RESULTS: A total of 136 patients (61 men and 75 women, were followed; 99 patients with venous thromboembolism and 37 with arterial disease; 59 were from Botucatu and 77 were from other municipalities. Thirty clinical events were registered: nine of them were not related to the use of warfarin and 21 were hemorrhagic complications (38.8 per 100 patients-year. One hematemesis was considered severe (1.9 per 100 patients-year. The others were considered moderate or mild. There were no deaths, intracranial hemorrhage or cutaneous necrosis. The only significant association was frequency of hemorrhage and average international normalized ratio level. CONCLUSION: Our results demonstrate the feasibility of this treatment in vascular patients in our country, even in socially and economically poor populations, when treated in specialized clinics.

  10. Provenance studies of archaeological ceramics from Mar-Takla (Ain-Minin, Syria) using radioisotope X-ray fluorescence method

    Institute of Scientific and Technical Information of China (English)

    2001-01-01

    The radioisotope X-ray fluorescence method was applied to studies of the provenance of the ceramics fragments originated from the Mar-Takla site in Syria. The samples were irradiated 1000s by a 109Cd radioisotope source and 13 elements (Ca, Ti, Mn, Fe, Zn, Ga, As, Rb, Sr, Y, Zr, Nb, and Pb) were determined in 35 samples. The data were subjected to two multivariate statistical methods, cluster and principal components analysis (PCA). It was shown from the combination of the statistical techniques and the determination of elemental composition of the samples that 94% of the ceramic samples analyzed can be considered to be manufactured using two sources of raw materials.

    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.

    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.

    2007-07-01

    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.

  15. Straight talk about high-fructose corn syrup: what it is and what it ain't.

    Science.gov (United States)

    White, John S

    2008-12-01

    High-fructose corn syrup (HFCS) is a fructose-glucose liquid sweetener alternative to sucrose (common table sugar) first introduced to the food and beverage industry in the 1970s. It is not meaningfully different in composition or metabolism from other fructose-glucose sweeteners like sucrose, honey, and fruit juice concentrates. HFCS was widely embraced by food formulators, and its use grew between the mid-1970s and mid-1990s, principally as a replacement for sucrose. This was primarily because of its sweetness comparable with that of sucrose, improved stability and functionality, and ease of use. Although HFCS use today is nearly equivalent to sucrose use in the United States, we live in a decidedly sucrose-sweetened world: >90% of the nutritive sweetener used worldwide is sucrose. Here I review the history, composition, availability, and characteristics of HFCS in a factual manner to clarify common misunderstandings that have been a source of confusion to health professionals and the general public alike. In particular, I evaluate the strength of the popular hypothesis that HFCS is uniquely responsible for obesity. Although examples of pure fructose causing metabolic upset at high concentrations abound, especially when fed as the sole carbohydrate source, there is no evidence that the common fructose-glucose sweeteners do the same. Thus, studies using extreme carbohydrate diets may be useful for probing biochemical pathways, but they have no relevance to the human diet or to current consumption. I conclude that the HFCS-obesity hypothesis is supported neither in the United States nor worldwide.

  16. 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.

  17. 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.

    Christen, Arden G; Christen, Joan A

    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.

    Robinson, Cynthia Cole; Clardy, Pauline

    2011-01-01

    The disparity between the cultural and linguistic diversity of the teaching population and the student population continues to grow as teacher education programs enroll and graduate primarily white teacher candidates (83.7%). At the same time, the diversity of the K-12 student body has increased with 65% of public school students being from culturally and linguistically diverse backgrounds (National Center for Education Statistics, 2007). This chasm between the diversity of the teaching force and student population is of concern as many teachers report that they do not have the cultural knowledge and experience of working or living in diverse environments, yet will be faced with teaching a very diverse student population. Hence, the need for teacher candidates and current teachers to be explicitly taught the skills needed to successfully teach diverse student populations is urgent. In this article, we explore the following phenomena: how linguistic and cultural diversity is regarded in teacher education programs, as well as teacher candidates' and current K-12 teachers' dispositions towards students who do not share their cultural backgrounds or language (including those who vary in their dialects). Finally, we will present strategies that teacher educators can use to embrace and empower culturally and linguistically diverse (CLD) teacher candidates, as well as prepare teacher candidates to teach diverse student populations.

    Full Text Available Rates of tobacco use in Greece are among the highest in Europe and are responsible for an enormous burden of chronic disease and death. A large proportion of tobacco users report an interest in quitting. Family medicine practices have been identified as important settings for identifying tobacco users, delivering advice to quit smoking, and providing tobacco treatment interventions. The 5A’s (ask, advice, assess, assist, arrange schema is an evidence-based model for addressing tobacco use in clinical settings. The rates at which primary care clinicians in Greece address tobacco use in their practice is unknown but, as in other countries, is understood to be sub-optimal. This paper describes the rationale, design, and protocol for a pre/post, controlled study to compare the effectiveness of a smoking cessation intervention delivered in primary care practices in Heraklion, Greece. The TiTAN-Crete intervention includes a 1-day tobacco treatment training program, dissemination of provider and patient resources and two booster training sessions. Participating providers and a cross-sectional sample of patients from their practices, will be surveyed. Outcome measures include changes in provider attitudes and beliefs, perceived behavioral control, intentions, and barriers related to smoking cessation treatment delivery. Rates at which providers deliver tobacco treatment to patients will be measured by patient report of 5As delivery. Multi-level modeling will be used to examine the effects of the intervention. This study will lead to a better understanding of how to best assist clinicians in Greece to enhance the rates at which smoking cessation treatments are delivered to smokers.

    Full Text Available This work presents the very first results of the application of plasma magnetic filtering achieved by a coil coupled with an electrical circuit of a coaxial accelerator during the synthesis of A1N thin films by use of Impulse Plasma Deposition method (IPD. The uniqueness of this technical solution lies in the fact that the filter is not supplied, controlled and synchronized from any external device. Our solution uses the energy from the electrical circuit of plasma accelerator. The plasma state was described on the basis of OES studies. Estimation of the effects of plasma filtering on the film quality was carried out on the basis of characterization of structure morphology (SEM, phase and chemical composition (vibrational spectroscopy. Our work has shown that the use of the developed magnetic self-filter improved the structure of the AlN coatings synthesized under the condition of impulse plasma, especially by the minimization of the tendency to deposit metallic aluminum droplets and columnar growth.

    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.

    Se ha realizado el estudio de regresión de las ecuaciones de Andrade, Krone, McAllister e Hildebrand con datos experimentales de viscosidad de mezclas de triglicéridos o ácidos grasos libres con tricloroetileno, tetracloroetileno y hexano en el intervalo de temperaturas de 278 a 313 K cada 5 K.
    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.

    2001-04-01

    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 estudiado la influencia del peso molecular del copolímero en la formación de geles físicos termoreversibles de copolímeros tribloque de la forma poliestireno-b-poli(etileno/butileno-b-poliestireno (SEBS en n-octano y en sus propiedades mecánicas. 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.

    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.

  16. 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.

  17. Ain't No Crab, PWN Got A Brand New Bag: Correlated radio and X-ray Structures in Pulsar Wind Nebulae

    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.

  19. The atomic world spooky? It ain't necessarily so! emergent quantum mechanics, how the classical laws of nature can conspire to cause quantum-like behaviour

    CERN Document Server

    van Holten, Theo

    2017-01-01

    The present book takes the discovery that quantum-like behaviour is not solely reserved to atomic particles one step further. If electrons are modelled as vibrating droplets instead of the usually assumed point objects, and if the classical laws of nature are applied, then exactly the same behaviour as in quantum theory is found, quantitatively correct! The world of atoms is strange and quantum mechanics, the theory of this world, is almost magic. Or is it? Tiny droplets of oil bouncing round on a fluid surface can also mimic the world of quantum mechanics. For the layman - for whom the main part of this book is written - this is good news. If the everyday laws of nature can conspire to show up quantum-like phenomena, there is hope to form mental pictures how the atomic world works. The book is almost formula-free, and explains everything by using many sketches and diagrams. The mathematical derivations underlying the main text are kept separate in a -peer reviewed - appendix.

  5. Impact of Dust from Ore Processing Facilities on Rain Water Collection Tanks in a Tropical Environment--The Obvious Source "Ain't Necessarily So".

    Science.gov (United States)

    Gulson, Brian; Korsch, Michael; Bradshaw, Anthony

    2016-02-22

    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.

    Science.gov (United States)

    Glazer, A M

    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.

  10. I Ain't Gonna Make It. Comparing Job Demands-Resources and Attrition Intention Between Senior Teachers and Senior Employees of Six Other Occupational Categories in Flanders.

    Van Droogenbroeck, Filip; Spruyt, Bram

    2016-07-01

    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.

  13. 'If it ain't broke, don't fix it?': scandals, 'risk', and cosmetic surgery regulation in the UK and France.

    Science.gov (United States)

    Latham, Melanie

    2014-01-01

    The recent PIP scandal that affected patients worldwide, and received extensive media coverage, led to concerns being felt by patients about the 'risks' of cosmetic surgery. Theories about regulation and risk refer to societies such as those in the West becoming more risk averse. Regulation, in turn, has come to be seen as an instrument to solve a problem for a community seen to be or which perceives itself to be at risk. The political and electoral risk acknowledged by government if it ignores that concern, or at least media coverage of it, can lead to regulation, or the tightening up of regulation, as a response. This article looks at current proposals for legislation in the UK following the PIP silicone implant scandal as an example of the risk-regulation premise. Are cosmetic surgery patients in the UK now going to see stricter regulation of the cosmetic surgery industry? The article argues that the UK and France have both reacted to healthcare scandals and the ensuing societal conception of risk by drawing up more thorough legislation on cosmetic surgery than previously existed. France enacted the Kouchner law in 2002 and the UK government published the Keogh Report in April 2013. A comparison is made of these to establish whether the UK can learn from the French legislation when it comes to drafting actual regulation in the future, perhaps in 2014. Finally, some arguments are made about whether risk aversion may make better law.

  20. 'It ain't what you do it's the way that you do it': lessons for health care from decommissioning of older people's services.

    Science.gov (United States)

    Robinson, Suzanne; Glasby, Jon; Allen, Kerry

    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.

    2016-10-01

    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.

    2016-12-01

    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.

    Full Text Available Background and introduction:Neck pain is a frequent and disabling complaint in general population. One ofthe most common causes of neck pain is mechanical dysfunction of cervical spine.Although diverse methodshave been proposed for increasing cervical range of motion, joint mobilisation has been confirmed aseffectivein several studies.The current study will compare the effect of three different treatment protocols i.e. Maitlandmobilisation, Mulligan mobilisation and conventional treatment on upper thoracic spine on female patientswith neck pain. This study tries to find out new effective method for reducing the problem of pain.Method:30 subjects were selected according to the inclusion and exclusion criteria were randomly dividedinto three groups: Maitland, Mulligan mobilization along with conventional treatment. Pre and post reading at0 day, 14thday and 21thdaywere recorded for NDI and NPRS scale.Results:After three week protocol it was found that all the three groups showed significant improvement inNDI and NPRS score within the group. The present finding shows that Group B (Maitland shows significantimprovements in the NDI score and Group C (Mulligan would shows significant improvements in the NPRSscores in the patients with nonspecific neck pain.Conclusion:The present study shows that Maitland mobilisation along with the conventional treatment proveto be more effective in improving NDI and NPRS scores in patients with nonspecific neck pain than Mulliganmobilisation along with the conventional treatment.

    Full Text Available The functions of dance and music in human evolution are a mystery. Current research on the evolution of music has mainly focused on its melodic attribute which would have evolved alongside proto-language. Instead, we propose an alternative conceptual framework which focuses on the co-evolution of rhythm and dance (R&D as intertwined aspects of a multimodal phenomenon characterized by the unity of action and perception. Reviewing the current literature from this viewpoint we propose the hypothesis that R&D have co-evolved long before other musical attributes and (proto-language. Our view is supported by increasing experimental evidence particularly in infants and children: beat is perceived and anticipated already by newborns and rhythm perception depends on body movement. Infants and toddlers spontaneously move to a rhythm irrespective of their cultural background. If this behavior is universal, R&D must have an essential function in human evolution. Conceivable evolutionary functions of R&D include sexual attraction, transmission of mating signals, synchronization of many individuals, social bonding, appeasement of hostile individuals, pre- and extra-verbal communication, improvement of body coordination, as well as pain killing, anti-depressive, and anti-boredom functions. The impulse to dance may have been prepared by the susceptibility of infants to be soothed by rocking. Dance enables embodied individual and collective memorizing; in many cultures R&D are used for entering trance, a base for shamanism and early religions. Rhythm is necessary to codify human speech and dance encompasses gesture. In future studies attention should be paid to which attribute of music is focused and that the close mutual relation between R&D is taken into account. The possible evolutionary functions of dance deserve more attention.

    A study was conducted to evaluate how the elderly population recognizes messages issued by public health officials and how they recall recommended protective measures. It also examined the protective measures adopted during heat waves and periods of smog as well as factors associated with the adoption of this behaviour. Elderly people suffering from chronic cardiac and respiratory diseases are most vulnerable to the effects of heat and smog. A survey of 151 elderly persons was conducted in the summer of 2004. The presentation included a discussion of the results of the descriptive analyses.

    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.

    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 plaquetas y la capacidad total de unión al hierro (TIBC) estaban elevados (p < 0,001), hallazgos consistentes con la anemia inducida experimentalmente en ratas.

    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.

    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 (HG)AIN 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 (HG)AIN. 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. PMID:24367625

    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.

A facilitação do acesso à unidade de saúde da família implantada em comunidade carente é limitada pela precariedade de infra-estrutura urbana do seu entorno. A unidade básica de saúde tem, nas grandes distâncias, a sua principal barreira de acesso. A inexistência de sistema de referência entre os distintos níveis de complexidade compromete o acesso dos pacientes a exames e especialistas. O cuidado oferecido nas duas unidades é restrito às queixas físicas passíveis de abordagem farmacológica, comprometendo a integralidade. Há baixa capacidade de escuta dos profissionais para problemas distintos do foco da ação programática. Destacam-se as potencialidades da utilização da etnografia na pesquisa avaliativa de sistemas e serviços de saúde.This paper analyzes the results of an evaluative study in the city of Manaus, Amazonas State, Brazil, on primary health care for patients with hypertension and/or diabetes. The ethnographic approach used access to services and comprehensiveness of health care as core analytical categories, comparing the health practices developed by Family Health Program (FHP units with traditional non-FHP primary care units. Access to family health care units in low-income communities is limited by the precarious surrounding urban infrastructure. The main barrier to access to primary care units is distance. The lack of a referral system between the various levels of complexity jeopardizes patients' access to tests and specialists. The care supplied by the two units is limited to patient conditions that can be treated pharmacologically, thus compromising the comprehensiveness of care. The health professionals display a limited capacity to hear problems outside the immediate focus of the program activity. The paper highlights the potential for using ethnography in evaluative research on health systems and services.

    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.

    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.

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

    Olivier Richel

    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.

    Anal intraepithelial neoplasia (AIN) is a premalignant lesion of the anal mucosa that is a precursor to anal cancer. Although anal cancer is relatively uncommon, rates of this malignancy are steadily rising in the United States, and among certain high risk populations the incidence of anal cancer may exceed that of colon cancer. Risk factors for AIN and anal cancer consist of clinical factors and behaviors that are associated with the acquisition and persistence of human papilloma virus (HPV) infection. The strongest HPV-associated risk factors are HIV infection, receptive anal intercourse, and high risk sexual behavior. A history of HPV-mediated genital cancer, which suggests infection with an oncogenic HPV strain, is another risk factor for AIN/anal cancer. Because progression of AIN to anal cancer is known to occur in some individuals over several years, screening for AIN and early anal cancer, as well as treatment of advanced AIN lesions, is reasonable in certain high-risk populations. Although randomized controlled trials evaluating screening and treatment outcomes are lacking, experts support routine screening for AIN in high risk populations. Screening is performed using anal cytological exams, similar to those performed in cervical cancer screening programs, along with direct tissue evaluation and biopsy via high resolution anoscopy. AIN can be treated using topical therapies such as imiquimod, 5-flurouracil, and trichloroacetic acid, as well as ablative therapies such as electrocautery and laser therapy. Reductions in AIN and anal cancer rates have been shown in studies where high-risk populations were vaccinated against the oncogenic strains of HPV. Currently, the CDC recommends both high-risk and average-risk populations be vaccinated against HPV infection using the quadrivalent or nonavalent vaccines. It is important for clinicians to be familiar with AIN and the role of HPV vaccination, particularly in high risk populations. PMID:28255426

    Full Text Available Resumen La enfermedad tromboembólica idiopática presenta un alto riesgo de recurrencia. Existe controversia respecto a la utilidad de la aspirina para disminuir la recurrencia luego de haber completado el tratamiento anticoagulante. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos cuatro revisiones sistemáticas que en conjunto incluyen dos estudios aleatorizados. Combinamos la evidencia utilizando metanálisis y generamos una tabla con síntesis de resultados según la metodología GRADE. Concluimos que la indicación de aspirina luego de haber completado el tratamiento anticoagulante disminuye la probabilidad de recurrencia y probablemente no aumenta de manera importante el riesgo de hemorragia.

    Quorum sensing, a group behaviour coordinated by a diffusible pheromone signal and a cognate receptor, is typical of bacteria that form symbioses with plants and animals. LuxIR-type N-acyl L-homoserine (AHL) quorum sensing is common in Gram-negative Proteobacteria, and many members of this group have additional quorum-sensing networks. The bioluminescent symbiont Vibrio fischeri encodes two AHL signal synthases: AinS and LuxI. AinS-dependent quorum sensing converges with LuxI-dependent quorum sensing at the LuxR regulatory element. Both AinS- and LuxI-mediated signalling are required for efficient and persistent colonization of the squid host, Euprymna scolopes. The basis of the mutualism is symbiont bioluminescence, which is regulated by both LuxI- and AinS-dependent quorum sensing, and is essential for maintaining a colonization of the host. Here, we used chemical and genetic approaches to probe the dynamics of LuxI- and AinS-mediated regulation of bioluminescence during symbiosis. We demonstrate that both native AHLs and non-native AHL analogues can be used to non-invasively and specifically modulate induction of symbiotic bioluminescence via LuxI-dependent quorum sensing. Our data suggest that the first day of colonization, during which symbiont bioluminescence is induced by LuxIR, is a critical period that determines the stability of the V. fischeri population once symbiosis is established.

  8. Allergic Interstitial Nephritis Manifesting as a Striated Nephrogram

    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.

    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

    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...

    A three-step growth process is developed for depositing high-quality aluminium-nitride (AIN) epilayers on (001) sapphire by low pressure metalorganic chemical vapour deposition (LP-MOCVD). We adopt a low temperature (LT) AIN nucleation layer (NL), and two high temperature (HT) AIN layers with different Ⅴ/Ⅲ ratios. Our results reveal that the optimal NL temperature is 840-880℃, and there exists a proper growth switching from low to high Ⅴ/Ⅲ ratio for further reducing threading dislocations (TDs). The screw-type TD density of the optimized AIN film is just 7.86×106 cm-2, about three orders lower than its edge-type one of 2×109 cm-2 estimated by high-resolution x-ray diffraction (HRXRD) and cross-sectional transmission electron microscopy (TEM).

    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.
