    Full Text Available La finalización intensiva de corderos en corrales elevados con piso de rejilla permite que los animales se mantengan en un ambiente sano, con menos carga parasitaria, protección de los depredadores, reducción en el gasto energético y un mejor microclima, sin embargo, poco se conoce sobre el comportamiento productivo de los corderos bajo este sistema de producción. La identificación de los factores que influyen sobre el comportamiento productivo de los corderos en este tipo de alojamiento es crucial para mejorar su productividad. El objetivo de este estudio fue determinar los efectos de granja, año y época del año sobre algunas variables productivas de corderos finalizados en corrales elevados con piso de rejilla en el trópico subhúmedo de México. Se analizaron 882 datos de la ganancia diaria de peso post-destete (GDP, del peso corporal final (PCF y del periodo de finalización (DE de corderos machos de cuatro granjas (granja A, n = 166; granja B, n = 122; granja C, n = 350; granja D, n = 244. El modelo estadístico incluyo los efectos fijos de la granja (A, B, C y D, de la época del año (lluvia y seca y del año (2010, 2011, 2012 y 2013 sobre GDP, PCF y DE. El modelo incluyó el peso corporal inicial como covariable. Las medias generales para GDP, PCF y DE fueron 263 g, 35 kg y 77 días, respectivamente. La granja afectó (P<0.001 todas las variables evaluadas. La época del año afectó (P<0.001 PCF y DE, pero no GDP. El año afectó (P<0.001 todas las variables evaluadas. La interacción granja × época del año afectó (P<0.001 PCF y DE, pero no GDP. En conclusión, el comportamiento productivo de corderos finalizados en jaulas elevadas en el trópico subhúmedo de México, fué afectado por la granja, el año y parcialmente por la época del año y la interacción granja × época del año.

    Full Text Available El objetivo del trabajo fue comparar el efecto de tres aditivos (dos probióticos y un antibiótico en el comportamiento productivo y la salud de cerdos en el período post- destete. Para esto se utilizaron 120 cerdos castrados, del cruce Landrace x Large White con padre Blanco Belga x Pietrain, de 28 d de edad y 6,87 kg, distribuidos en tres grupos experimentales según diseño completamente aleatorizado con cuatro repeticiones cada uno. Los tratamientos (T evaluados fueron: 1 kg de virginiamicina al 2% por tonelada de alimento (T1, 1 kg de probiótico con Saccharomyces cerevisiae, Bacillus subtilis y enzimas digestivas por tonelada de alimento (T2 y 15 mL de preparado ecuatoriano con bacterias lácticas, levaduras y enzimas por kg de peso vivo (PV de los animales (T3. En este último grupo fue donde se obtuvo el mayor peso vivo final (25,85 kg, P<0.0001 y la mejor ganancia de peso total (18,97 kg, P<0.0001 y diaria (451,75 g/d, P<0.0001. También, para el mismo grupo se encontraron las conversiones de materia seca, proteína bruta y energía metabolizable más eficientes (1,52 kg/kg de PV; 381,57 g/kg de PV y 22,99 MJ/kg de PV, respectivamente. El porcentaje de animales con diarreas difirió (P<0,0001 entre el grupo que recibió la virginiamicina (50,61% y los aditivos microbianos (27,98% y 21,39%, sin diferencias entre estos últimos. Se concluye que los aditivos microbianos mejoran el comportamiento productivo y sanitario de cerdos en post-destete con respecto a la virginiamicina, y este efecto fue mayor con el preparado microbiano ecuatoriano.

    Full Text Available El objetivo del trabajo fue medir el rendimiento de la canal y la calidad de la carne de corderos alimentados con pasto, suplementados con caña de azúcar fermentada en forma aeróbica. Se llevó a cabo en dos sitios. Se trabajó con un grupo de 13 corderos de 11.5 kg de peso vivo inicial, estabulados y alimentados con pasto, suplementados con caña de azúcar fermentada en Cunduacán, Tabasco, y 24 corderos con 20 kg de peso vivo inicial, semiestabulado en pastoreo con pasto Estrella Africana, suplementados con caña de azúcar fermentada, en Huimanguillo, Tabasco. Se sacrificaron a un peso de 32 kg. Los resultados fueron analizados mediante estadística descriptiva. La ganancia diaria de peso fue de 109 y 85 g para el sistema Cunduacán y Huimanguillo, respectivamente. El peso y rendimiento de la canal en frío y caliente fue de 13.5 y de 14.14 kg, 42.04 y 43.09% y 40.28 y 41.45%, para el sistema Cunduacán y Huimanguillo, respectivamente. La relación entre el peso al sacrificio con el rendimiento de la canal tuvo correlación negativa de -0.41. Las piezas de mayor peso fueron, pierna, costilla/falda, lomo y paleta. La capacidad de retención de agua fue 12.78, 12.8, y elpH, 5.49 y 5.71, para el sistema Cunduacán y Huimanguillo, respectivamente. El color de la grasa fue blanco para las canales de ovinos, en ambos sitios. Se concluye que los corderos de pelo alimentados con pasto y caña fermentada producen canales con bajo rendimiento magro y con grasa de color blanca.

    Full Text Available A interrupção prematura da amamentação pode acarretar perigos, pois os alimentos a serem utilizados são inadequados do ponto de vista nutricional, além de expor a criança a organismos infecciosos. Torna-se relevante investigar os fatores relacionados ao desmame precoce. Pesquisa exploratória e quantitativa, realizada no Centro de Desenvolvimento da Família (CEDEFAM, no período de maio a junho/2003, com 20 nutrizes, no qual foi aplicado um questionário contendo 12 questões sobre os motivos que as levaram a desmamarem precocemente. Os resultados foram agrupados em três segmentos: fatores de desmame relacionados com o perfil; a assistência pré-natal e o parto; e prática do aleitamento materno, e apresentados em forma de tabelas. Concluímos que os profissionais e a sociedade podem não estar preparados para favorecer a mulher no exercício da amamentação. Enquanto isso, a política de saúde não cria condições para que todos tenham acesso à educação, melhoria de renda e conscientização do planejamento familiar.La interrupción precoz del destete puede resultar en peligros, pues los alimentos utilizados son considerados por los nuticionistas como inadecuados, además de exponer al niño a organismos infecciosos.

    Full Text Available Objetivo. Determinar las prevalencias de lactancia humana, uso de leches industrializadas y ablactación así como los factores asociados a la falta de alimentación al seno materno y al destete temprano. Material y métodos. Estudio transversal realizado por pasantes de medicina en Servicio Social en 222 localidades rurales de México, mediante entrevistas estructuradas en 5 409 familias con niños menores de un año. Resultados. Las proporciones de niños que nunca recibieron lactancia al seno materno fueron: en la zona norte (N de 21.4%; en la centro (C de 7.6% y la sur (S de 5.3%. Entre los niños que recibieron lactancia al seno materno, ésta continuó en forma exclusiva o mixta hasta el tercer trimestre de vida en 35.6% (N, 67.6% (C y 77.5% (S; en el segundo trimestre de vida ya habían sido ablactados 67.2% (N, 40.9% (C y 51.6% (S. En la región N se encontró que la falta de alimentación al seno materno se asoció con la atención médica del parto, madres con escolaridad mínima de primaria o con menos de cuatro hijos, casa con piso de material permanente, dos o más enseres domésticos mayores y que el sostén económico no fuera el padre. El destete temprano se asoció con los mismos factores, incluyendo que el niño estuviera al cuidado de una persona distinta a la madre, la lactancia artificial decidida por los padres o por recomendación médica, la ablactación temprana y el uso de servicios médicos de seguridad social y/o privados. Conclusiones. La alimentación con sucedáneos de la leche y el destete temprano son propios de familias pequeñas, con mayor educación materna, mejores condiciones de la vivienda y la influencia de los médicos, sobre todo en el norte del país. Además, la ablactación se efectúa antes del segundo semestre de vida, por lo que es recomendable elaborar programas que promuevan la alimentación al seno materno y la ablactación correcta en la población infantil de las comunidades rurales de México.

  12. Geochemistry of batch-extract waters derived from spoil material collected at the Cordero coal mine, Powder River basin, Wyoming

    Naftz, D.L.

    1990-01-01

    Batch-mixing experiments to evaluate postmining water quality at the Cordero Mine were conducted by the U.S. Geological Survey during 1984 to 1985. Contact of groundwater from the spoil aquifer with fresh spoil material caused only small changes in major-element concentrations and in pH, unless sulfide oxidation or contact with soluble salts, such as epsomite, occurred. In contrast, large changes in major-element concentration resulted when water from the coal aquifer contacted the spoil material. Only three of seven reaction models considered to explain the water quality changes during the batch-mixing experiments were consistent with the thermodynamic and mineralogical data. The three models used to account for the observed water quality changes derived potassium from potassium feldspar; magnesium from chlorite or epsomite or both; sodium from cation exchange and halite; chloride from halite; silica from potassium feldspar and chlorite; sulfate from gypsum, or epsomite or both, and carbon from carbon dioxide. In general, water quality samples obtained from the batch-mixing experiments using water from the coal aquifer had smaller major-ion concentrations than the actual water quality in the spoil aquifer. These differences can be explained by the limited amount of efflorescent salt dissolution and volume of water used in the experiments. Correction ratios calculated for these experiments may be applied to batch-mixing experiments at other mines in the area, to predict postmining water quality. (USGS)

    Objetivo: teniendo en cuenta el consumo frecuente de dietas ricas en grasas por las mujeres en edad reproductiva, el objetivo del presente estudio fue investigar los efectos del consumo materno de una dieta alta en grasas durante el periodo perinatal y/o post-destete en el higado y el metabolismo de los lipidos en ratas jovenes. Métodos: ratas hembra Wistar fueron alimentadas durante el embarazo y la lactancia con un alto contenido de grasa (H) o de control (C). La descendencia se asigno a cuatro grupos: Control (CC, n = 11), descendencia alimentada con una dieta de control despues del destete; Control de dieta alta en grasa (CH, n = 10), crias alimentadas con una dieta alta en grasas despues del destete; Alta en grasas de alta en grasa (HH, n = 10), hijos de madres H alimentados con una dieta alta en grasas despues del destete; y Control de alta en grasa (HC, n = 9), hijos de madres H alimentados con dieta de control tras el destete. Resultados y discusión: la ingesta de alimentos no difirio entre los grupos; sin embargo, el peso relativo del tejido adiposo fue mayor en los animales de los grupos HC, HH y CH (p ≤ 0,005). La esteatosis hepatica se encontro en los CH y HH, que tambien presentaban hipercolesterolemia (p ≤ 0,05). Los niveles de las enzimas hepaticas alanina aminotransferasa (ALT) y gamma-glutamil transpeptidasa (GGT) fueron mayores en el grupo de HH, y el nivel de LDL fue mayor en el grupo CH en comparacion con el CC. El consumo de la dieta propicio la obesidad durante los periodos criticos del desarrollo y puede contribuir a la aparicion de obesidad visceral, esteatosis hepatica e hipercolesterolemia en ratas adultas, incluso en ausencia de cambios en la ingesta dietetica.

    Full Text Available Para caracterizar el desarrollo de los epidídimos, se castraron corderos Blackbelly al nacimiento y cada tres semanas hasta la 21 (n=4 a 6 por grupo. Se registró el peso de los epidídimos y de las tres regiones anatómicas y se tomaron muestras para morfometría. Se calculó el porcentaje de tejido tubular, el diámetro tubular, el grosor y área de la capa muscular, la altura y área del epitelio, y el diámetro y área de la luz tubular. El mayor crecimiento del epidídimo se observó entre las semanas 9 y 18; la cola comenzó a desarrollarse antes que las otras regiones; el peso de ésta fue mayor entre el nacimiento y la semana 12, pero de la semana 15 a la 21 no difirió de la cabeza. En general, el diámetro tubular, el grosor y área de la capa muscular y el diámetro y área de la luz fueron mayores en la cola. La altura del epitelio fue mayor en la cola hasta la semana 9, pero la situación se invirtió a partir de la semana 12. De acuerdo a lo que se conoce de esta raza, la cola comenzó a desarrollarse antes de aparecer la luz de los túbulos seminíferos y del aumento de las concentraciones de testosterona, mientras que el desarrollo de la cabeza y el cuerpo coincidió con el aumento de la capacidad esteroidogénica y la secreción del fluido tubular. Tales hallazgos sugieren diferentes requerimientos de estimulación endocrina y lumicrina para el desarrollo normal de las diferentes regiones del epidídimo.

El modelo matemático propuesto incluyó los efectos fijos año, época, sexo, número de partos, finca y sugieren el efecto aleatorio de padre para ambas características. Resultados. Se encontró que los efectos finca y padre fueron estadísticamente significativos para el (PN. En cuanto PD, el año fue estadísticamente significativo (p£0.05, los efectos sexo, número de partos y padre resultaron altamente significativos (p£0.05 y los efectos época y finca no significativos (p³0.05. Los estimados de heredabilidad fueron 0.16 y 0.37 para el PN y PD, respectivamente. Los valores de las correlaciones genéticas, fenotípicas y ambientales fueron respectivamente -0.2, 0.14 y 0.26. Conclusión. Los valores hallados para la heredabilidad indican que el fenotipo no es un buen indicador de su genotipo, debiendo recurrir para la selección de estos a la prueba de progenie o pedigrí. El valor de las correlaciones genéticas permite afirmar que las crías con mejores pesos al nacimiento no serán las que alcancen mayores pesos al destete.

    Coppo, J.A

    2007-07-01

    Full Text Available En los sistemas de cría extensiva de vacunos para carne del nordeste argentino, el destete tradicionalmente se realiza a los 6-8 meses, cuando el ternero ha alcanzado pesos de alrededor de 150 kg. Esta prolongada lactación deteriora la condición corporal de los vientres, retrasando su retorno a la ciclicidad estral e interfiriendo el objetivo productivo de destetar un ternero por vaca y por año. Tales inconvenientes son subsanados con el destete precoz, efectuado a los 2-3 meses con terneros de no menos de 70 kg quienes -a la fecha del destete convencional- habitualmente no consiguen equiparar sus pesos con los de aquéllos que lactaron al pie de madre (diferencia: -20 kg. Esta menor velocidad de crecimiento se atribuye al estrés del destete precoz, aunque no existen trabajos científicos que convaliden esta hipótesis con evidencias irrefutables, especialmente en terneros cruza cebú. Con el objetivo de investigar dicha hipótesis a través de cambios del medio interno, en cuatro años sucesivos se realizaron ensayos de destete precoz que en total involucraron 120 animales (30 por año, 60 en lactación al pie de madre (78.9 6.9 kg sobre pastura natural (controles, lote C y 60 (experimentales, lote E sometidos a destete precoz (77.8 7.0 kg, estos últimos suplementados con alimento balanceado (16% proteínas, EM = 2.77 Mcal/kg MS a razón del 1.5% PV (inicial y 0.7% PV (final.

    Full Text Available El presente estudio caracterizó el desarrollo testicular, evaluó la asociación existente entre el perímetro escrotal (PE y el volumen testicular (VOL e identificó los parámetros testiculares en la pubertad en machos de la raza guzerat. Se evaluaron 330 machos que totalizaron 1757 observaciones realizadas cada tres meses, desde el destete hasta los 36 meses. Se realizaron mediciones del PE, longitud y ancho testiculares. Se calculó el VOL siguiendo el método descrito por Fields et ál. Los animales que presentaron PE ≥ 20 cm fueron sometidos a la recolección de semen utilizando estímulo electroeyaculatorio. Se consideraron púberes los animales que presentaron por lo menos un espermatozoide móvil en el eyaculado. La curva de desarrollo testicular se describió utilizando la función logística, siendo el punto de inflexión máximo del perímetro escrotal y del volumen testicular a los 13,2 meses de edad (18,1 cm y 23,3 meses de edad (389,4 cm3, respectivamente. La tasa de crecimiento promedio del perímetro escrotal y volumen testicular antes y después del punto de inflexión fueron respectivamente 0,58 cm/m; 16,3 cm3/m; 0,29 cm/m; 7,7 cm3/meses de edad. La edad promedio en la pubertad fue de 19,6 meses, con 250,6 kg de peso, 22,8 cm de perímetro escrotal y 284,7 cm3 de volumen testicular. La proporción de machos púberes en la franja de 12-16 meses fue de 7,4 %; de 16-20 meses, 41,23 %; de 20-24, 68 %; de 24-28 fue de 91,96 %. A los 24 meses de edad 91,96 % de los animales se encontraban púberes. Se verificó una alta correlación positiva entre PE y VOL (r = 0,91; P < 0,001. Estos resultados indican que en la raza guzerat el perímetro escrotal predice de forma eficiente el volumen escrotal, pudiendo ser usado como una medida segura para la selección de jóvenes reproductores.

LPS activates a coordinated series of signs that involve the MAPK family, initiating a cascade of reactions that interrupt nutrient transport processes and can progress to multiple organic failure. The aim of this study was to determine the effect of adding ex vivo different levels of lipopolysaccharide of E. coli on lysine absorption in weaned pigs. The experiment was carried out with 16 weaned pigs 21 days old. Animals were fed during 10 days with a basal diet with milk and some of its derivatives.

El objetivo es conocer dicha distribución en la especie ovina. Se estudiaron improntas de médula ósea obtenidas de vértebras torácicas de 30 corderos. Fueron teñidas con Diff-Quik y se contaron el número de núcleos en 204 osteoclastos La curva de frecuencias fue de carácterasimétrico con una media de 8.3 ± 3.5, una mediana de 6 núcleos porosteoclasto y un índice de curtosis de –0,04. Se puede concluir que elpatrón de distribución de los núcleos en osteoclastos de la especie ovina es similar al de otros mamíferos,entre ellos, el hombre.SummaryThe osteoclasts, multinucleated cells, are involved in boneresorption, a process with an increasing interest in cellular biology and pathology. Many authors have studied the distribution of nuclei in osteoclasts of several species in order to go into cellular dynamics in depth and search models in animals to apply to human diseases. Our aim is to know the osteoclasts nuclei distribution in ovine species. Bone marrow preparations of thoracic vertebra of 30 lambs were studied, using Diff- Quik and counting the number of nuclei in 204 osteoclasts. The curve of the frequencies was asymmetric with an average of 8.3 ± 3.5, a median of 6 nuclei per osteoclast and a curtosis index of –0,04. We could conclude that the pattern of distribution of the nuclei of the osteoclasts in ovine is similar to other mammals, and then, to humans.

The aim of this study was to evaluate the effect of dryland legume pastures on the fatty acid composition of lamb meat. The study included 21 Suffolk Down male lambs aged about 2-mo that were randomly assigned to three types of pastures: successional pasture, subterranean clover/Wimmera ryegrass (Trifolium subterraneum L./Lolium rigidum Gaudin, or red clover/Wimmera ryegrass (T.pratense L./L. rigidum for 66 d, and slaughtered after. The fatty acid profile measured in the Longissimus dorsi muscle showed no significant differences as to the content of saturated (SFA, polyunsaturated fatty acids (PUFA, and the omega6/omega3 rate (co6/co3. There was a trend (p > 0.06 towards a higher monounsaturated fatty acid (MUFA content in the meat of lambs fed on red clover when compared to the other pasture types. Although there were no significant differences among treatments, the results obtained with natural pasture cannot be extrapolated to natural dryland pastures due to their high legume content. It is concluded that using subterranean clover/Wimmera ryegrass would provide a similar meat quality when compared to results obtained from forage based on red clover/Wimmera ryegrass.La producción ovina en el secano está basada en la pradera natural.

Material y métodos. Estudio transversal realizado por pasantes de medicina en Servicio Social en 222 localidades rurales de México, mediante entrevistas estructuradas en 5 409 familias con niños menores de un año. Resultados. Las proporciones de niños que nunca recibieron lactancia al seno materno fueron: en la zona norte (N de 21.4%; en la centro (C de 7.6% y la sur (S de 5.3%. Entre los niños que recibieron lactancia al seno materno, ésta continuó en forma exclusiva o mixta hasta el tercer trimestre de vida en 35.6% (N, 67.6% (C y 77.5% (S; en el segundo trimestre de vida ya habían sido ablactados 67.2% (N, 40.9% (C y 51.6% (S.

El destete temprano se asoció con los mismos factores, incluyendo que el niño estuviera al cuidado de una persona distinta a la madre, la lactancia artificial decidida por los padres o por recomendación médica, la ablactación temprana y el uso de servicios médicos de seguridad social y/o privados. Conclusiones. La alimentación con sucedáneos de la leche y el destete temprano son propios de familias pequeñas, con mayor educación materna, mejores condiciones de la vivienda y la influencia de los médicos, sobre todo en el norte del país. Además, la ablactación se efectúa antes del segundo semestre de vida, por lo que es recomendable elaborar programas que promuevan la alimentación al seno materno y la ablactación correcta en la población infantil de las comunidades rurales de M

Three treatments were compared in a completely randomized experiment using 36 single male Suffolk Down lambs with an initial age and live weight of 80 d and 25 kg, respectively. The three treatments were: (a suckling lambs kept with their mothers on annual Mediterranean grassland (GRAZE; (b weaned stall-fed lambs on a control ration (CONC; and (c weaned stall-fed lambs on an olive cake-based ration (CAKE. At the end of the 28-d experimental period, lambs were slaughtered, carcass quality evaluated, and samples of subcutaneous fat analyzed for fatty acids. Treatments did not differ in weight gain or carcass weight and quality, but highly significant differences were found in several fatty acid contents. CAKE animals had reduced palmitic acid as well as increased oleic and stearic acid contents. Atherogenic and thrombogenic indices improved with cake feeding. Principal component and discriminant analyses clearly differentiated treatments suggesting they could be applicable for traceability purposes. A laboratory experiment demonstrated that with or without added vitamin E, the dry olive cake did not alter its lipid properties with increased storage time.El propósito del experimento aquí reportado fue determinar en qué grado se puede modificar la composición y calidad de la carcasa de corderos con el suministro de una ración basada en el alperujo de oliva, en comparación con una ración convencional o con el pastoreo directo.

Estos resultados sugieren que la raza Dorper puede ser usada en esquemas de cruzamiento para mejorar la producción de carne ovina en zonas áridas como las del noroeste de México.The aim of this study was to evaluate feedlot performance and carcass characteristics of 36 male and female lambs from the genotypes pure Pelibuey, Dorper x Pelibuey, and Katahdin x Pelibuey under desert conditions in northwestern Mexico. Lambs were slaughtered for carcass evaluation after 85 d of a productive performance test. Dorper x Pelibuey lambs had higher (P 0.05 among the three genotypes in carcass yield, Longissimus dorsi muscle area and back-fat thickness. Males presented higher (P 0.05 between sexes. Yield and total weight of primary cuts were also similar (P > 0.05 among genotypes and sexes. These findings suggest that the Dorper breed can be used in crossbreeding schemes to improve mutton production in arid zones, like in northwestern Mexico.

Nowadays, technical progress allows manufacturers to develop flexible fiberglass posts, aspiring not only to an excellent aesthetics and mechanical properties (first of all, in comparison with metal and cast posts), but also to maintenance of their radio density and a wide range of forms. Growth of fiberglass posts popularity testifies to their clinical efficiency that also is confirmed by results of long-term researches. Introduction of fiberglass posts in a dental practice has rendered huge influence on restoration techniques of root canal treatment. Convincing factors of fiberglass posts superiority provide restoration the appearance similar with the natural dentition; possess close to dentine elasticity; creation of monolithic structure with hard tooth tissues and composite cement, posts, in case of need, can be easily adjusted on length, adhesive linkage of posts gives them additional stability. Modern researches have confirmed that only elastic, namely carbon fiber and the fiberglass posts made of modern technologies possess similar physical properties, as tooth structure. They can create reliable biomimetic design; solve a complex of aesthetic and functional restoration problems.

    Parčina, Ivana; Amižić

    2016-01-01

    The primary function of an endodontic post is to provide retention for the core and enable full sealing of the coronal portion of the root canal. Traditionally used metal posts do not meet the requirements of modern dental medicine due to some fairly significant drawbacks such as color, corrosion potential, non-adhesive bonding and high modulus of elasticity which can lead to root fracture. Recently, esthetic ceramic and fiber reinforced posts have been manufactured in order to avoid such imperfections. Since much attention has been devoted to the esthetic aspects of dental medicine, the use of these posts with composite/ceramic cores is very common in restorative dentistry and it is actually becoming a standard. This is due to the fact that, apart from being an esthetically pleasing material, they are also biocompatible, have good physical properties and the capacity of adhesive bonding to tooth tissue and core buildup. Nonetheless, a good clinician should know how to spot the difference between them in order to select and use the appropriate post system in each specific situation. PMID:27789912

    CERN Multimedia

    1995-01-01

    LHC support post prototype, which dates in 1995, in a long development period which started in the early ’90s and continued until the end of the decade. The wires next to the support post are probably wires from strain gauges, which are employed to measure the stress level in the material when the support is mechanically loaded. These supports are mechanically optimized to withstand a weight of up to 100Kn (10 tons) while being as thin as possible to minimize conduction heat to magnets. This is the reason why the stress measurement was extensively done in the prototyping phase. About support posts: The high magnetic fields needed for the LHC can only be reached using superconductors. At very low temperatures, superconductors have no electrical resistance and therefore no power loss. The LHC will be the largest superconducting installation ever built and, at 1.9 degrees above absolute zero (300 degrees below room temperature), one of the the coldest objects in the universe! The magnet supports have to brid...

    These telangiectasia appear between one and six months after the operation, especially in cases of capillary fragility. The most common localizations are the antero-internal and external sides of the thighs and knees. Unnecessary strippings, of continent saphenous veins, are the most frequent cause of these. Their prevention consists of the least possible traumatising stripping, using a fine stripper, a very rigorous post-operative support, and the wearing of light varicose stockings or tights for between one and three months. The treatment using microsclerosis, often delicate, should not be undertaken before six months.

    To establish guidelines of the French National College of Gynecologists and Obstetricians about post-abortion contraception. A systematic review of the literature about post-abortion contraception was performed on Medline and Cochrane Database between 1978 and March 2016. The guidelines of the French and foreign scientific societies were also consulted. After an abortion, if the woman wishes to use a contraception, it should be started as soon as possible because of the very early ovulation resumption. The contraception choice must be done in accordance with the woman's expectations and lifestyle. The contraindications of each contraception must be respected. The long-acting reversible contraception, intra-uterine device (IUD) and implant, could be preferred (grade C) as the efficacy is not dependent on compliance. Thus, they could better prevent repeat abortion (LE3). In case of surgical abortion, IUD should be proposed and inserted immediately after the procedure (grade A), as well as the implant (grade B). In case of medical abortion, the implant can be inserted from the day of mifépristone, the IUD after an ultrasound examination confirming the success of the abortion (no continuing pregnancy or retained sac) (grade C).

    Our aim was to assess the acceptability and cost-efficiency of shared consultancy posts. Two consultant physicians worked alternate fortnights for a period of twelve months. Questionnaires were distributed to general practitioners, nurses, consultants and junior doctors affected by the arrangement. Patients or their next of kin were contacted by telephone. 1\\/17 of consultants described the experience as negative. 14\\/19 junior doctors reported a positive experience. 11 felt that training had been improved while 2 felt that it had been adversely affected. 17\\/17 GPs were satisfied with the arrangement. 1\\/86 nurses surveyed reported a negative experience. 1\\/48 patients were unhappy with the arrangement. An extra 2.2 (p<0.001) patients were seen per clinic. Length of stay was shortened by 2.49 days (p<0.001). A saving of 69,212 was made due to decreased locum requirements. We present data suggesting structured shared consultancy posts can be broadly acceptable and cost efficient in Ireland.

    Secondary tics are those in which an aetiology justifying them can be found, as compared to idiopathic tics, which make up the majority, and the Gilles de la Tourette syndrome (SGT), which is, at the moment, of unknown origin. Of the possible aetiologies described as causing tics, craneo-encephalic trauma has been mentioned on very few occasions. We present a case of post-traumatic tics (verbal and neck) in a young man of 24, and review the published cases which can be considered to be of post-traumatic tics. We have found six cases of tics secondary to traumas, all craneo-encephalic, like ours (the one under study). The time interval between the blow and the appearance of the tic or tics varied between 2 weeks and 3 months. The absence of significant lesions seen in the complementary investigations make it impossible for us to discover the site of the lesion caused by the trauma. However, the presence in some cases of other tics before the trauma, and of family histories of tics, supports the idea of a genetic basis or predisposition to suffer this disorder.

It has been shown that olfaction and visionare equally effective in allowing the calf identification by its dam, and that abolition of both senses attenuate the negative effects ofsuckling on luteinizing hormone (LH secretion. This review indicatesthat the net effects of suckling or pseudo-suckling on the centralregulation of tonic LH release are determined by the ability of thedam to identify the calf as its own or as unrelated. The use of several nursing systems (i.e. early weaning, temporary weaning andrestricted suckling to achieve early post-partum ovarian cyclicity are discussed.

  16. Post-Quantum Cryptography

    DEFF Research Database (Denmark)

    Gauthier Umana, Valérie

    The security of almost all the public-key cryptosystems used in practice depends on the fact that the prime factorization of a number and the discrete logarithm are hard problems to solve. In 1994, Peter Shor found a polynomial-time algorithm which solves these two problems using quantum computers....... The public key cryptosystems that can resist these emerging attacks are called quantum resistant or post-quantum cryptosystems. There are mainly four classes of public-key cryptography that are believed to resist classical and quantum attacks: code-based cryptography, hash-based cryptography, lattice......-cyclic alternant codes and quasi-dyadic codes (joint work with Gregor Leander). We also present a deterministic polynomial-time algorithm to solve the Goppa Code Distinguisher problem for high rate codes (joint work with Jean-Charles Faugere, Ayoub Otmani, Ludovic Perret and Jean-Pierre Tillich).

    Rob Kitchin

    2010-03-01

    Full Text Available Over the past decade there has been a move amongst critical cartographers to rethink maps from a post-representational perspective – that is, a vantage point that does not privilege representational modes of thinking (wherein maps are assumed to be mirrors of the world and automatically presumes the ontological security of a map as a map, but rather rethinks and destabilises such notions. This new theorisation extends beyond the earlier critiques of Brian Harley (1989 that argued maps were social constructions. For Harley a map still conveyed the truth of a landscape, albeit its message was bound within the ideological frame of its creator. He thus advocated a strategy of identifying the politics of representation within maps in order to circumnavigate them (to reveal the truth lurking underneath, with the ontology of cartographic practice remaining unquestioned.

    Post-16 Initiative logo This is the first of a regular series of contributions from the Institute's Post-16 Initiative. The Initiative is taking a hard and searching look at the physics taught in schools and colleges from age 16 to age 19. To start with, it is responding to Government initiatives, but hopes to encourage and stimulate good practice in physics teaching on a longer time scale than can be afforded in making responses to current developments. Here Jon Ogborn writes about what AS courses need to be, while Peter Campbell gives his thoughts about teaching matter. Advanced Subsidiary physics: what should it be? From September 2000 all A-levels will be new. Students can take the first Advanced Subsidiary (AS) year and stop there - or decide to go on. In the Institute of Physics post-16 Initiative, we have been thinking how to provide a satisfying one-year experience of physics at the new AS level, and what it should achieve. The students will decide. So the AS course must give a decent picture of what physics is, what it offers for their futures, what interests it can satisfy. That all says breadth, with enough depth to see what is in store later. And this sounds like the right recipe for someone who is taking a single AS year of physics to broaden their A-level experience. It must also be attractive. A way forward is shown by the Salters - Horners course, attracting interest through leading from applications. Why does that work? It gives physics a story to tell, into which ideas fit and make sense. Our own new A-level, Advancing Physics, must also have interesting stories to tell, which must in addition build up an honest picture of physics. An example: teach electric circuits through modern sensing devices. Sensor instrumentation is a key activity of physicists, full of new ideas, but also simple. It makes essential use of circuits such as the potential divider. Practical work gets better things to do than checking the equation for resistors in parallel

    The purpose of this work is to study the fundamentals of post combustion and the effect of different process parameters on the post combustion ratio (PCR) and heat transfer efficiency (HTE) in converter steelmaking process. The PCR and HTE have been determined under normal operating conditions. Trials assessed the effect of lance height, vessel volume, foaming slag and pellet additions on PCR and HTE. Based on enthalpy considerations, post combustion of CO gas is regarded as one of the most effective means of increasing the heat supply to the BOP. The thermodynamic study of gas-metal-slag reactions gives the limiting conditions for post combustion inside the converter reactor. Different process parameters influencing both thermodynamic equilibria and kinetic conditions can greatly affect the post combustion ratio. Different features of converter processes as well smelting reduction processes utilizing post combustion have been reviewed. (orig.) SULA 2 Research Programme; 26 refs.

    post16.gif As a teacher of physics it is very easy to become preoccupied with particulars of courses, or topics or even single concepts. Concerned with imminent student audiences and desired learning outcomes, the daily challenge is to summon satisfactory teaching approaches and resources for the job at hand. For the conscientious teacher, assessment outcomes may too often seem a judgment on our own efforts rather than those of our students. From time to time we may step back and think bigger, for example while planning a recruitment event, or while away from work on holiday. We may be successful locally. But why, at a time when books and television documentaries popularizing science have a large following, has physics education been facing declining numbers? Many recognize that physics has an essential contribution to make to the training of science or engineering specialists, but we know that it is also important for the skilled worker, the informed citizen and, in fact, for anyone trying to make sense of the world. So what are the best ways forward for post-16 physics? To make any impact on the bigger picture requires organization, thinking and meeting time among people in diverse roles: teachers and curriculum managers; university lecturers; employers and professional bodies; unitary awarding bodies; regulatory and funding agencies; and even Government. For the past few years, the Institute of Physics post-16 Initiative has created an unrivalled opportunity to address the wider issues. Its Shaping the Future booklets series was designed to stimulate informed discussion and debate, by providing background information and analysis. Taken together, the booklets should help all those concerned with physics education to understand where we are now, and why. Literally dozens of people have contributed to a review and analysis of physics education. Each booklet is a 48-page smorgasbord in A4 landscape format, containing many examples of good practice, basic but

    Many ICU patients struggle to recovery following critical illness and may be left with physical, cognitive and psychological problems, which have a negative impact on their quality of life. Gross muscle mass loss and weakness can take some months to recover after the patients' Intensive Care Unit (ICU) discharge, in addition critical illness polyneuropathies can further complicate physical recovery. Psychological problems such as anxiety, depression and post traumatic stress disorder (PTSD) are common and have an negative impact on the patients' ability to engage in rehabilitation after ICU discharge. Finally cognitive deficit affecting memory can be a significant problem. The first step in helping patients to recover from such a devastating illness is to recognise those who have the greatest need and target interventions. Research now suggests that there are interventions that can accelerate physical recovery and reduce the incidence of psychological problems such as anxiety, depression and PTSD. Cognitive rehabilitation, however, is still in its infancy. This review will look at the research into patients' recovery and what can be done to improve this where needed.

    (post16) Making physics connect Doesn't Melvyn Bragg do a wonderful job, engaging both scientists and artists in sensitive discussion on Radio 4 about their methods and their purposes? But every week teachers have the chance to show their students that physics is a way of seeing the world that is well-connected with other aspects of knowledge and culture. The stakes are high: students who fail to appreciate this generally choose not to study the subject beyond GCSE. Most students find our preoccupation with technical detail off-putting. Accepting that we have a syllabus to cover, it's still a question of balance. In our teaching we should aim for variety in order to find ways to connect with every student's interests. Also, we can show that we (the nearest embodiment of a physicist some students will experience) are multidimensional and so fully human. Most important, teachers need flexibility to both encourage and respond to student comment and questions. The first booklet in the discussion series Shaping the Future takes up these themes. Rich in ideas for both immediate use and the longer term, it aims to stimulate debate and improve teaching. Copies cost £5.50 including postage and are available from Ingrid Ebeyer, Post-16 Initiative, Institute of Physics, 76 Portland Place, London W1N 3DH. How far is it?

    Post-16 Initiative logo Physics in Mathematical Mood Later this year, as part of the post-16 initiative of the Institute of Physics, a booklet with the above title will be published. In draft form, the booklet was discussed at the ASE conference in January. Some of the issues raised are briefly set out here. If you have any views to contribute, please write to Simon Carson at the Institute of Physics or e-mail simon.carson@physics.org. A mathematical view of the world is intrinsically a part of physics and therefore physics should be studied in an appropriately mathematical way. However, we all know that, to some students at least, mathematics proves to be a stumbling block rather than a powerful aid to understanding. So how can we help? Realizing that as physics teachers we need to deliver the mathematics necessary to an understanding of our subject is a start. Its corollary is that we need to find the space within the physics core. We may wish to use supplementary courses such as AS mathematics or QCA's new free-standing mathematics units, but requiring additional courses as a prerequisite to a study of A-level physics may deter students. Teaching the mathematics in context may aid understanding but we also must ensure that techniques are seen in a variety of contexts and that at some point the tool is abstracted from the background. As teachers we need to be aware of the very basic mathematical difficulties that students bring with them: the use of calculators, standard form, simple algebraic manipulation, for example. Mathematical arguments need to be developed fully and carefully. Encouraging cooperation and discussion between students may help the less able to understand and the more able to appreciate and develop their own understanding through making explicit their reasoning by explaining it to others. And what of new technology? Software tools allow students to develop their understanding about graphs, for example, enabling them to investigate the

    Full Text Available Aim of the study is to describe the phenomenon of post-religion as a specific spiritual sphere of the Post-modernity. Methodology. In the introduction analyzed a variety of methodological approaches, opening his inadequacy applied to the spiritual sphere of Post-modernity: «classic» religious studies, religious studies of traditional spiritual movements and the post-modern religious studies, partly produced Traditionalist school, could - according to the author's hypothesis - become a methodological basis for the most complete analysis of post-religion. Scientific novelty. In the main part of the article crystallized the authorized concept of post-religion, its relation with traditional and religious spiritual realms. Post-religion is positioned as the top of secularism enshrined in the departure from the straight and aggressive secularism of the Modernity, but without recourse to Tradition. Post-religion a simulation spirituality, skillfully imitating the outer areas of traditional spirituality and creates a planar religiosity, radically preventing attached to the vertical line of Traditions. In this regard, are the main artificially selected parameters of post-religion: deconstruction, splitting, virtualization, and collage. Deconstruction is a transformation of spirituality in semiotic set for egocentric selectivity of modern believer. Post-religion’s splitting is deprivation of spirituality center, destruction of sacral Center and the transformation of spirituality in the plane on which the intellectual and sensual wandering post-believer from one semiotic island to another. Virtualization is a displacement field of spiritual tension in a completely virtual area, isolated from the natural conditions of existence and created as his replacement, network discussion sites and galleries. Collage is an arbitrary combination of different semiotic pieces of Tradition with the aim of creating a believable picture of tradition; it is collage leads

    Post-mortem microbiology is useful in both clinical and forensic autopsies, and allows a suspected infection to be confirmed. Indeed, it is routinely applied to donor studies in the clinical setting, as well as in sudden and unexpected death in the forensic field. Implementation of specific sampling techniques in autopsy can minimize the possibility of contamination, making interpretation of the results easier. Specific interpretation criteria for post-mortem cultures, the use of molecular diagnosis, and its fusion with molecular biology and histopathology have led to post-mortem microbiology playing a major role in autopsy. Multidisciplinary work involving microbiologists, pathologists, and forensic physicians will help to improve the achievements of post-mortem microbiology, prevent infectious diseases, and contribute to a healthier population.

    Institute of Physics post-16 initiative, shaping the future Physics education based in IT - sorry ICT! Which, of course, makes for a nifty headline, but as is so often the case with neat slogans, little else. Two formative questions: What, in another decade, will the government of the day call `What you lot should be doing with computers'? and What, of the many things that currently exercise our intellects, will there be anything special to say about in a decade, concerning the use of computers in the teaching of physics? Advancing Physics represents some attempts to come to grips with the second of the two questions above. The first is left to a higher wisdom. In thinking about learning, what can we do with the huge processing power, increasingly available in smaller and less obtrusive packages? What will we do that helps people learn physics, both tomorrow and in 2009? Here are a few suggestions based on development work so far. Wide, reliable and shared access to well ordered learning resources. We have created a CD-ROM, with versions for both student and teacher, that provides a wide range of resources. These do not teach, but do provide. A commitment to allowing a course to evolve and adapt. Electronic publication puts the costs into origination, and not into publication and distribution. A website allows for the community of users to contribute. E-mail networks support individuals and propagate good practice. You can create and explore your own microworlds. The interactive nature of models, and the crafted relationships between the models and the natural world give an insight into the creative imaginary worlds of the physicist. The unreasonable, but pleasurable, success of mathematics in describing the natural world can come to the fore. Measurements that were not possible before are now possible. What was previously indirect, and inaccessible, now becomes a direct measurement, making relationships transparent in new and fruitful ways. The dichotomy between

  20. Post-operative urinary retention.

    Science.gov (United States)

    Steggall, Martin; Treacy, Colm; Jones, Mark

    Urinary retention is a common complication of surgery and anaesthesia. The risk of post-operative urinary retention is increased following certain surgical procedures and anaesthetic modalities, and with patients' advancing age. Patients at increased risk of post-operative urinary retention should be identified before surgery or the condition should be identified and treated in a timely manner following surgery. If conservative measures do not help the patient to pass urine, the bladder will need to be drained using either an intermittent catheter or an indwelling urethral catheter, which can result in catheter-associated urinary tract infections. This article provides an overview of normal bladder function, risk factors for developing post-operative urinary retention, and treatment options. Guidance drawn from the literature aims to assist nurses in identifying at-risk patients and inform patient care.

    1989-12-01

    While school enrolments have been rising, the absolute number of illiterates in the world has grown too. Eradication of adult illiteracy and universalization of primary education are hindered by high drop-out in schools and relapse into illiteracy among adults. Post-literacy programmes seek to stop this reversal by ensuring retention, application and continuation of literacy skills. The Unesco Institute for Education (UIE) has been researching and promoting post-literacy strategies since 1980, but finds that most projects do not include provision for post-literacy from the outset, despite the evident need. Those programmes which have been mounted use a variety of strategies, which UIE has analysed in 12 categories. The exact delimitation of the post-literacy stage in the lifelong education continuum differs from project to project, and the emphasis on individual or societal advance depends on local perceptions of the goals of development. Examples are given of successful programmes, and the challenges of increasing participation and motivation, securing adequate funding, and making efficient and flexible use of institutional facilities are discussed.

    Full Text Available Post-partum period is demanding period characterized by overwhelming biological, social and emotional changes. It requires significant personal and interpersonal adaptation, especially in case of primigravida. Childbearing from the standpoint of psychological medicine is the most complex event in human experience. Traditionally Inwood has classified post-partum psychiatric disorders (PPPD as maternity blues, post-partum (postnatal depression and puerperal psychosis (PP. However the spectrum of postpartum phenomenology is widely characterized by range of emotions from transient mood liability, irritability and weepiness to marked agitation, delusions, confusion and delirium. Untreated post-partum depression can have adverse long term effects. For the mother, the episode can be the precursor of chronic recurrent depression. For her children a mother's ongoing depression can contribute to emotional, cognitive and interpersonal problems in later life. And therefore a thorough knowledge of the same is important for all obstetrician and gynecologists. [Int J Reprod Contracept Obstet Gynecol 2016; 5(8.000: 2497-2502

    Research was conducted into the problems of avoiding collision between separated payloads and spent rocket motors due to post burnout thrust, and the problem of contamination of scientific instrumentation due to outgassing of the smoldering insulation. The post burnout thrust was measured using a payload instrument module separated from an instrumented Black Brant VC Rocket in the exoatmosphere. In addition to measuring acceleration and velocities the spent motor was observed by a TV camera on board the command attitude controlled payload module. Analysis shows that the payload separated cleanly from the vehicle at a relative separation velocity of 0.69 m/sec, however the residual thrust of the spent motor overcame this differential, catching up to the payload 37 sec after separation and continuing on a parallel velocity vector at about 1.03 m/sec.

    2015-01-01

    About 10% of patients with Lyme disease continue to experience musculoskeletal pain and cognitive dysfunction after recommended antibiotic treatment. This condition is called post-Lyme disease syndrome (PLDS) or post-treatment Lyme disease syndrome. These two terms are used interchangeably. The pathogenesis of PLDS has been controversial. The hypothesis that patients with PLDS may harbor hidden reservoirs of Borrelia burgdorferi after their initial antibiotic treatment is difficult to accept. The prospective, double-blind studies contradict this point of view. Also, recently published research applying xenodiagnosis to PLDS supports the opinion that PLDS most likely has an autoimmune background. Lengthy courses of antibiotics are not justified in patients with PLDS because of the lack of benefit, and they are fraught with hazards. Most patients with PLDS recover from persistent symptoms with time. However, it can take months before they feel completely well.

    The significance of orthodontic treatment in the aetiology of temporomandibular dysfunction continues to be a matter of controversy. However, the evidence of any association has been generally negative. This investigation involved the examination of a study group of 87 post-orthodontic patients, the average time out of all retention being 52 months. They were compared with an untreated control group. Signs and symptoms of temporomandibular disfunction were assessed for both groups. In only one instance, soft joint click, was there found to be a significant association between the treatment category and the occurrence of the symptom, there being a higher rate of soft clicks in the post-treatment group. While this may be ascribed to orthodontic treatment, there was also a different restorative pattern in the two groups. No other significant associations were found.

Clinical and laboratory research over the last 30 years has shown that use of smaller-gauge needles, particularly of the pencil-point design, are associated with a lower risk of PDPH than traditional cutting point needle tips (Quincke-point needle. A careful history can rule out other causes of headache. A postural component of headache is the sine qua non of PDPH. In high-risk patients < 50 years, post-partum, in the event a large-gauge needle puncture is initiated, an epidural blood patch should be performed within 24–48 hours of dural puncture. The optimum volume of blood has been shown to be 12–20 mL for adult patients. Complications caused by autologous epidural blood patching (AEBP are rare.Keywords: post-dural puncture headache, gauge, needles, cause, risk, incidence

    2006-03-01

    Full Text Available Abstract Aortic stenosis is the most common valvular heart disease affecting up to 4% of the elderly population. It can be associated with dilatation of the ascending aorta and subsequent dissection. Post-stenotic dilatation is seen in patients with AS and/or aortic regurgitation, patients with a haemodynamically normal bicuspid aortic valve and following aortic valve replacement. Controversy exists as to whether to replace the aortic root and ascending aorta at the time of aortic valve replacement, an operation that potentially carries a higher morbidity and mortality. The aetiology of post-stenotic aortic dilatation remains controversial. It may be due to haemodynamic factors caused by a stenotic valve, involving high velocity and turbulent flow downstream of the stenosis, or due to intrinsic pathology of the aortic wall. This may involve an abnormality in the process of extracellular matrix remodelling in the aortic wall including inadequate synthesis, degradation and transport of extracellular matrix proteins. This article reviews the aetiology, pathology and management of patients with post-stenotic aortic dilatation.

  20. Parameterized post-Newtonian cosmology

    Science.gov (United States)

    Sanghai, Viraj A. A.; Clifton, Timothy

    2017-03-01

    Einstein’s theory of gravity has been extensively tested on solar system scales, and for isolated astrophysical systems, using the perturbative framework known as the parameterized post-Newtonian (PPN) formalism. This framework is designed for use in the weak-field and slow-motion limit of gravity, and can be used to constrain a large class of metric theories of gravity with data collected from the aforementioned systems. Given the potential of future surveys to probe cosmological scales to high precision, it is a topic of much contemporary interest to construct a similar framework to link Einstein’s theory of gravity and its alternatives to observations on cosmological scales. Our approach to this problem is to adapt and extend the existing PPN formalism for use in cosmology. We derive a set of equations that use the same parameters to consistently model both weak fields and cosmology. This allows us to parameterize a large class of modified theories of gravity and dark energy models on cosmological scales, using just four functions of time. These four functions can be directly linked to the background expansion of the universe, first-order cosmological perturbations, and the weak-field limit of the theory. They also reduce to the standard PPN parameters on solar system scales. We illustrate how dark energy models and scalar-tensor and vector-tensor theories of gravity fit into this framework, which we refer to as ‘parameterized post-Newtonian cosmology’ (PPNC).

    2016-02-01

    Lyme disease is a chronic infectious disease caused by the bacteria, spirochete of the Borrelia type. Skin, nervous system, musculoskeletal system and heart may be involved in the course of the disease. The prognosis for properly treated Lyme disease is usually good. However, in about 5% of patients so called Post-Lyme disease syndrome (PLSD) develops. It is defined as a syndrome of subjective symptoms persisting despite proper treatment of Borrelia burgdorferi infection. The most common symptoms include: fatigue, muscle and joint pain, and problems with memory and concentration. Pathogenesis of PLDS remains unknown. The differential diagnosis should include neurological, rheumatic and mental diseases. Till now there is no causative treatment of PLDS. In relieving symptom rehabilitation, painkillers, anti-inflammatory and antidepressants medicines are recommended. Emotional and psychological supports are also necessary. Non-specific symptoms reported by patients with post- Lyme disease syndrome raise the suspicion of other pathologies. This can lead to misdiagnosis and implementation of unnecessary, potentially harmful to the patient's therapy. An increase in tick-borne diseases needs to increase physicians awareness of these issues. © 2016 MEDPRESS.

    Sanghai, Viraj A A

    2015-01-01

    We construct a framework to probe the effect of non-linear structure formation on the large-scale expansion of the universe. We take a bottom-up approach to cosmological modelling by splitting our universe into cells. The matter content within each cell is described by the post-Newtonian formalism. We assume that most of the cell is in the vicinity of weak gravitational fields, so that it can be described using a perturbed Minkowski metric. Our cells are patched together using the Israel junction conditions. We impose reflection symmetry across the boundary of these cells. This allows us to calculate the equation of motion for the boundary of the cell and, hence, the expansion rate of the universe. At Newtonian order, we recover the standard Friedmann-like equations. At post-Newtonian orders, we obtain a correction to the large-scale expansion of the universe. Our framework does not depend on the process of averaging in cosmology. As an example, we use this framework to investigate the cosmological evolution ...

  7. Post-representational cartography Cartografia post-rappresentativa

    Directory of Open Access Journals (Sweden)

    Rob Kitchin

    2010-03-01

    Full Text Available Over the past decade there has been a move amongst critical cartographers to rethink maps from a post-representational perspective – that is, a vantage point that does not privilege representational modes of thinking (wherein maps are assumed to be mirrors of the world and automatically presumes the ontological security of a map as a map, but rather rethinks and destabilises such notions. This new theorisation extends beyond the earlier critiques of Brian Harley (1989 that argued maps were social constructions. For Harley a map still conveyed the truth of a landscape, albeit its message was bound within the ideological frame of its creator. He thus advocated a strategy of identifying the politics of representation within maps in order to circumnavigate them (to reveal the truth lurking underneath, with the ontology of cartographic practice remaining unquestioned.

  11. "Deprovincializing" sociology: the post colonial contribution

    Directory of Open Access Journals (Sweden)

    Sérgio Costa

    2007-01-01

    Full Text Available This essay discusses the contributions of post-colonial studies for renewing the contemporary social theory. At first it considers the character of the critique addressed by post-colonial studies to social sciences. After that, it analyses the post-colonial epistemological alternatives, considering three interrelated concepts: entangled modernity, "hybrid" site of enunciation, and decentralized subject. The conclusion is that, in spite of its severity and suspicion among some authors that post-colonial theory can destroy epistemological foundations of social sciences, an important part of post-colonial critique is rather addressed to the theory of modernization. Here, post-colonial positions present affinities with objections, which have already been presented by "conventional" social scientists. Other aspects raised by post-colonial authors do not destabilize, necessarily, social sciences; they can even enrich them.

  12. Management Of Post Stroke Seizures

    Directory of Open Access Journals (Sweden)

    Kavian Ghandehari

    2017-02-01

    Full Text Available The incidence of seizures in relation to stroke is 8.9%, with a frequency of 10.6 and 8.6% in haemorrhagic and ischaemic stroke, respectively. In subarachnoid haemorrhage the incidence is 8.5%. Due to the fact that infarcts are significantly more frequent than haemorrhages, seizures are mainly related to occlusive vascular disease of the brain. The general view is to consider stroke-related seizures as harmless complications in the course of a prolonged vascular disease involving the heart and brain. Seizures can be classified as those of early and those of late onset in a paradigm comparable to post-traumatic epilepsy, with an arbitrary dividing point of two weeks after the event. Most early-onset seizures occur during the first day after the stroke. Late-onset seizures occur three times more often than early-onset ones. A first late-onset epileptic event is most likely to take place between six months and two years after the stroke. However, up to 28% of patients develop their first seizure several years later. Simple partial seizures, with or without secondary generalisation, account for about 50% of total seizures, while complex partial spells, with or without secondary generalisation, and primary generalised tonic–clonic insults account for approximately 25% each. Status epilepticus occurs in 12% of stroke patients, but the recurrence rate after an initial status epilepticus is not higher than after a single seizure. Inhibitory seizures, mimicking transient ischaemic attacks, are observed in 7.1% of cases. The only clinical predictor of late-onset seizures is the initial presentation of partial anterior circulation syndrome due to a territorial infarct. Patients with total anterior circulation syndrome have less chance of developing epileptic spells, not only due to their shorter life expectancy but also due to the fact that the large infarcts are sharply demarcated in these patients. The optimal timing and type of antiepileptic drug

    Post-tubal ligation syndrome includes pain during intercourse, aching lower back, premenstrual tension syndrome, difficulty in menstruating, uterine hemorrhage, and absence of menstruation. The syndrome is caused by blood circulation problems in and around the Fallopian tubes and ovaries, pressure on nerves, and intrapelvic adhesion. Differentiating between this syndrome and endometritis during diagnosis and differentiating between functional hemorrhage due to hormonal abnormality and anatomical hemorrhage due to polyp or tumor is very important. Since the symptoms of this syndrome are mild, simple symptomatic treatment is sufficient in most cases. In some cases, however, desquamation surgery or reversal of tubal ligation may be necessary. Endoscopic surgery is also available. In Japan, because of widespread use of condoms and IUDs, tubal ligation is not very common.

    This is the concept for a series of post-shot investigations at the Piledriver site, Area 15, Nevada Test Site (NTS), to gain information on: Chimney geometry and associated wall rock conditions resulting from a deeply buried (1500-ft) nuclear explosion in granite; The characteristics and distribution of rubble and radioactivity in the chimney; and Data pertinent to in-situ leaching. These categories define the three phases of this proposal in chronological order. The technical programs under Phases II and III will depend on the results of Phase 1. Presently, it is not known whether or not there has been a collapse of the Piledriver cavity. If collapse occurred, the predicted dimensions of the chimney, based on Hardhat experience, are expected to be 250 ft in diameter and 560 ft high. For the purpose of this discussion, it is assumed this condition exists.

    clock skew operation is performed only at the clock sinks in order to preserve the structure and the optimizations implemented in the clock tree synthesis stage. The methodology is implemented as a linear programming model amenable to two design objectives: fixing timing violations or optimizing the clock period. Experimental results show that the clock networks of the largest ISCAS'89 circuits can be corrected post-CTS to resolve the timing conflicts in approximately 90% of the circuits with minimal delay insertion (0.159  ×  clock period per clock path on average. It is also shown that the majority of the clock period improvement achievable through unrestricted clock skew scheduling are obtained through very limited insertion (≈43% average improvement through 10% of max insertion.

    Highlights: • This study is the result of collaboration between neuroradiologists and neurosurgeons. • Comparison between neuroimaging techniques to better evaluate the complications after treatment of the spin. • Evaluation of the imaging features of complications and definition of follow-up. - Abstract: Any surgical approach modifies the normal anatomical and functional arrangement of the segmental spine which is aimed, therefore image interpretation cannot ignore a correct set of knowledge in the field of anatomy, pathophysiology, drug compliance, interventional radiology and surgery. Neuroradiological imaging has an important role before surgery to direct the surgeon or interventional radiologist during the operation, both in post-surgery, where imaging examination can rightly evaluate properties and effects of the treatment and can detect potential complications as infections, abscess, bleeding, exuberant scar, mobilization and rupture of devices.

Imaging assessment of spine after surgery is complex and depends upon several factors, including surgical procedures and disease for which it was performed; biomechanical of the underlying cortical and cancellous bone findings; conditions of muscles, intervertebral disk and ligaments; time since surgery procedures; duration and nature of the post-surgical syndrome. Depending upon several factors, one or a combination of complementary imaging modalities (X-rays, Computed Tomography, Magnetic Resonance) may be required to evaluate effectiveness of the treatment; to demonstrate any clinically relevant abnormality at the treated region and adjacent structures (complications such as inflammation, abscesses, bleeding and misplacement of the device); to

    Full Text Available To evaluate the maternal and fetal outcomes in renal transplant female recipients who became pregnant from 1989 to 2005 in our center, we retrospectively studied 20 incident pregnancies in 12 renal transplant recipients; 5 (41.7 % of them from living related, 4 (33.3% from deceased, and 3 (25% from living unrelated donors. The mean age at pregnancy was 30.5 ± 4.5 years and mean interval from transplantation to pregnancy was 21 ± 5.7 months with the interval was < 1 year in one patient. The mean serum creatinine (SCr before pregnancy vs 6 months post delivery was 110 ± 24.3, and 156 ± 190 µmol/ L, respectively, (p = 0.2. All patients were normotensive during the prenatal period except two who were hypertensive, none was markedly proteinuric, and only one acute rejection episode occurred during one pregnancy. Graft loss one year post delivery occurred in 2 patients; one with elevated prenatal SCr > 132 µmol/L, and another with short interval from transplantation to pregnancy < 1 year, while the remaining 10 patients revealed current mean SCr of 105 ± 18.2 µmol/L. Complications during pregnancy inclu-ded pre-eclampsia in (25%, UTI (25%, preterm delivery < 37 weeks (30%, however, none of the pregnancies ended by abortion. Normal vaginal delivery vs cesarean section was 70% vs 30%, respectively. Gestational age at delivery was 36.3 ± 3.9 weeks, and mean fetal birth weight was 2349 ± 574 gm. Apgar score was 9-10 in all of the 20 babies, and none revealed intrauterine growth retardation or congenital anomalies. We conclude that consecutive pregnancies demons-trate long-term maternal and fetal survival and function. The major risk factors are elevated starting serum creatinine, hypertension, and short time interval from transplantation to pregnancy.

LeFort colpocleisis (LFC is a safe and effective obliterative surgical option for older women with advanced pelvic organ prolapse who no longer desire coital activity. A major disadvantage is the limited ability to evaluate for post-LFC gynecologic malignancies. Methods. We present the first case of endometrioid ovarian cancer diagnosed after LFC and review all reported gynecologic malignancies post-LFC in the English medical literature. Results. This is the second reported ovarian cancer post-LFC and the first of the endometrioid subtype. A total of nine other gynecologic malignancies post-LFC have been reported in the English medical literature. Conclusions. Gynecologic malignancies post-LFC are rare. We propose a simple 3-step strategy in evaluating post-LFC malignancies.

    The aim of this study was to analyze the radiopacity and filler content of three experimental glass fiber posts (EGFP) in comparison with other glass/carbon fibers and metal posts from the dental market. Three EGFP were obtained by pultrusion of glass fibers in a polymer matrix based on 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)-phenyl]propane (bis-GMA) and triethyleneglycol dimethacrylate (TEGDMA) monomers. Using intraoral sensor disks 27 posts, as well as mesiodistal sections of human molar and aluminum step wedges were radiographed for evaluation of radiopacity. The percentage compositions of fillers by weight and volume were investigated by combustion analysis. Two EGFP showed radiopacity higher than enamel. The commercial endodontic posts showed radiopacity as follows: higher than enamel, between enamel and dentin, and lower than dentin. The results showed statistically significant differences (p < 0.05) when evaluated with one-way ANOVA statistical analysis. According to combustion analyses, the filler content of the tested posts ranges between 58.84 wt.% and 86.02 wt.%. The filler content of the tested EGFP ranged between 68.91 wt.% and 79.04 wt.%. EGFP could be an alternative to commercial glass fiber posts. Future glass fiber posts are recommended to present higher radiopacity than dentin and perhaps ideally similar to or higher than that of enamel, for improved clinical detection. The posts with a lower radiopacity than dentin should be considered insufficiently radiopaque. The radiopacity of some glass fiber posts is not greatly influenced by the amount of filler. - Highlights: • AR glass fibers for dental applications • AR glass fibers have a great potential for obtaining radiopaque glass fiber posts. • Experimental AR glass fiber posts could be an alternative to commercial glass fiber posts for clinical application.

    2009-03-15

    There has been recent interest in radiation-induced bone injury in clinical conditions, especially for pelvic insufficiency fracture (PIF). A PIF is caused by the effect of normal or physiological stress on bone with demineralization and decreased elastic resistance. Pelvic radiotherapy (RT) can also contribute to the development of a PIF. A PIF has been regarded as a rare complication with the use of megavoltage equipment. However, recent studies have reported the incidence of PIFs as 8.2{approx}20% after pelvic RT in gynecological patients, an incidence that was higher than previously believed. The importance of understanding a PIF lies in the potential for misdiagnosis as a bony metastasis. If patients complain of pelvic pain after whole-pelvis radiation therapy, the presence of a PIF must be considered in the differential diagnosis. The use of multibeam arrangements and conformal RT to reduce the volume and dose of irradiated pelvic bone can be helpful to minimize the risk of fracture. In addition to a PIF, osteonecrosis and avascular necrosis of the femoral head can develop after radiation therapy. Osteoradionecrosis of the pelvic bone is a clinical diagnostic challenge that must be differentiated from an osseous metastasis. A post-radiation bone sarcoma can result as a long-term sequela of pelvic irradiation for uterine cervical cancer.

  10. Post orgasmic illness syndrome (POIS)

    Science.gov (United States)

    2016-01-01

    Men with post orgasmic illness syndrome (POIS) become ill rather immediately after ejaculation, whether spontaneously at night, during sexual intercourse or masturbation. Two subtypes are distinguished: primary and secondary POIS. It also occurs before or after a man has been sterilized. POIS is an invalidating most probably auto-immune disease leading to much distress in males and their partners. It is characterized by five criteria. Its symptoms are described by seven clusters. However, the manifestation of these symptoms varies from one male to the other but is relatively constant in the person himself. Among men the symptoms vary in intensity, durations and sort of symptoms. POIS is a chronic disorder that manifests itself in POIS “attacks” that occur within a few minutes to a few hours after ejaculation, and disappear spontaneously after 3 to 7 days. POIS is not associated with increased total serum IgE concentrations. On the contrary, there are indications that POIS is triggered by specific cytokines that are released by an auto-immune reaction to the man’s seminal fluid. Indirect clinical evidence suggests that the antigen (Ag) triggering the POIS systemic reaction is not bound to spermatozoa but to seminal fluid produced by prostatic tissue. In addition, POIS may also occur—although rarely—in females. In those cases, it is hypothesized that the Ag is associated with female prostatic tissue around the vagina. PMID:27652231

  13. Parameterized Post-Newtonian Cosmology

    CERN Document Server

    Sanghai, Viraj A A

    2016-01-01

    Einstein's theory of gravity has been extensively tested on solar system scales, and for isolated astrophysical systems, using the perturbative framework known as the parameterized post-Newtonian (PPN) formalism. This framework is designed for use in the weak-field and slow-motion limit of gravity, and can be used to constrain a large class of metric theories of gravity with data collected from the aforementioned systems. Given the potential of future surveys to probe cosmological scales to high precision, it is a topic of much contemporary interest to construct a similar framework to link Einstein's theory of gravity and its alternatives to observations on cosmological scales. Our approach to this problem is to adapt and extend the existing PPN formalism for use in cosmology. We derive a set of equations that use the same parameters to consistently model both weak fields and cosmology. This allows us to parameterize a large class of modified theories of gravity and dark energy models on cosmological scales, ...

  14. Post-Retrofit Residential Assessments

    This study examined a range of factors influencing energy consumption in households that had participated in residential energy-efficiency upgrades. The study was funded by a grant from the U.S. Department of Energy’s Pacific Northwest National Laboratory and was conducted by faculty and staff of Portland State University Center for Urban Studies and Department of Economics. This work was made possible through the assistance and support of the Energy Trust of Oregon (ETO), whose residential energy-efficiency programs provided the population from which the sample cases were drawn. All households in the study had participated in the ETO Home Performance with Energy Star (HPwES) program. A number of these had concurrently pursued measures through other ETO programs. Post-retrofit energy outcomes are rarely investigated on a house-by-house basis. Rather, aggregate changes are ordinarily the focus of program impact evaluations, with deviation from aggregate expectations chalked up to measurement error, the vagaries of weather and idiosyncrasies of occupants. However, understanding how homes perform post-retrofit on an individual basis can give important insights to increase energy savings at the participant and the programmatic level. Taking a more disaggregated approach, this study analyzed energy consumption data from before and after the retrofit activity and made comparisons with engineering estimates for the upgrades, to identify households that performed differently from what may have been expected based on the estimates. A statistical analysis using hierarchal linear models, which accounted for weather variations, was performed looking separately at gas and electrical use during the periods before and after upgrades took place. A more straightforward comparison of billing data for 12-month periods before and after the intervention was also performed, yielding the majority of the cases examined. The later approach allowed total energy use and costs to be

    2005-10-01

    Acceptance of lower transfusion thresholds and shorter post-operative stays results in patients leaving hospital after surgery with lower haemoglobin (Hb) than previously. We undertook a prospective observational study to assess the haematological response to post-operative anaemia and to determine the utility of quality of life (QoL) measures in assessing the impact of anaemia on such patients. Thirty patients undergoing unilateral hip arthroplasty had blood samples taken and QoL questionnaires administered pre-operatively and at 7, 28 and 56 days post-operatively. Increased erythropoiesis was evident at day 7 post-operatively. Approximately two-thirds of the post-operative Hb deficit was corrected by day 28. There was evidence of functional iron deficiency in more than one-quarter of patients at day 56. QoL scores used did not show any relationship with Hb in the post-operative period. Red cell 2,3-diphosphoglycerate (2,3DPG) levels increased in proportion to the degree of post-operative anaemia. We concluded that substantial recovery of Hb occurs between day 7 and day 28 post-operatively. Complete recovery of Hb may be delayed beyond day 56 due to development of iron deficiency. Patients are at significant risk of developing post-operative iron deficiency depending on operative blood loss and pre-operative iron stores. Increased red cell 2,3DPG may offset the effect of anaemia on oxygen delivery. We found no evidence that anaemia produces a measurable effect on chosen QoL scores in the post-operative period.

    2013-06-01

    To guarantee sufficient food supply for a growing world population, efforts towards improving crop yield and plant resistance should be complemented with efforts to reduce post-harvest losses. Post-harvest losses are substantial and occur at different stages of the food chain in developed and developing countries. In recent years, a substantially increasing interest can be seen in the application of proteomics to understand post-harvest events. In the near future post-harvest proteomics will be poised to move from fundamental research to aiding the reduction of food losses. Proteomics research can help in reducing food losses through (i) identification and validation of gene products associated to specific quality traits supporting marker-assisted crop improvement programmes, (ii) delivering markers of initial quality that allow optimisation of distribution conditions and prediction of remaining shelf-life for decision support systems and (iii) delivering early detection tools of physiological or pathogen-related post-harvest problems. In this manuscript, recent proteomics studies on post-harvest and stress physiology are reviewed and discussed. Perspectives on future directions of post-harvest proteomics studies aiming to reduce food losses are presented.

    Furtos, Gabriel; Baldea, Bogdan; Silaghi-Dumitrescu, Laura

    2016-02-01

    The aim of this study was to analyze the radiopacity and filler content of three experimental glass fiber posts (EGFP) in comparison with other glass/carbon fibers and metal posts from the dental market. Three EGFP were obtained by pultrusion of glass fibers in a polymer matrix based on 2,2-bis[4-(2-hydroxy-3-methacryloyloxypropoxy)-phenyl]propane (bis-GMA) and triethyleneglycol dimethacrylate (TEGDMA) monomers. Using intraoral sensor disks 27 posts, as well as mesiodistal sections of human molar and aluminum step wedges were radiographed for evaluation of radiopacity. The percentage compositions of fillers by weight and volume were investigated by combustion analysis. Two EGFP showed radiopacity higher than enamel. The commercial endodontic posts showed radiopacity as follows: higher than enamel, between enamel and dentin, and lower than dentin. The results showed statistically significant differences (p b 0.05)when evaluatedwith one-way ANOVA statistical analysis. According to combustion analyses, the filler content of the tested posts ranges between 58.84wt.% and 86.02wt.%. The filler content of the tested EGFP ranged between 68.91 wt.% and 79.04 wt.%. EGFP could be an alternative to commercial glass fiber posts. Futureglass fiber posts are recommended to present higher radiopacity than dentin and perhaps ideally similar to or higher than that of enamel, for improved clinical detection. The posts with a lower radiopacity than dentin should be considered insufficiently radiopaque. The radiopacity of some glass fiber posts is not greatly influenced by the amount of filler.

  5. Vistas of the post-industrial city.

    prosperity, as redundant industrial buildings are re-coded as sites of culture. But if the post-industrial city is a post-modern site of abundance, its benefits are unevenly distributed; centres of affluence construct margins of deprivation. Just as public art lent a veneer of cultural value to urban development in the 1980s, so the re-coding of industrial buildings as sites of culture in the ’90s contributes to a continuing aestheticisation of the city which affirms a dominant spatial order. What strategies, then, are appropriate for art in post-industrial cities?

    Full Text Available Unexpected extreme sudden traumatic stressor may cause post-traumatic stress disorder (PTSD. Important traumatic events include war, violent personal assault (e.g., sexual assault, and physical attack, being taken hostage or kidnapped, confinement as a prisoner of war, torture, terrorist attack, severe car accidents, and natural disasters. In childhood age sexual abuse or witnessing serious injuries or unexpected death of a beloved one are among important traumatic events.PTSD can be categorized into two types of acute and chronic PTSD: if symptoms persist for less than three months, it is termed “acute PTSD,” otherwise, it is called “chronic PTSD.” 60.7% of men and 51.2% of women would experience at least one potentially traumatic event in their lifetime. The lifetime prevalence of PTSD is significantly higher in women than men. Lifetime prevalence of PTSD varies from 0.3% in China to 6.1% in New Zealand. The prevalence of PTSD in crime victims are between 19% and 75%; rates as high as 80% have been reported following rape. The prevalence of PTSD among direct victims of disasters was reported to be 30%–40%; the rate in rescue workers was 10%–20%. The prevalence of PTSD among police, fire, and emergency service workers ranged from 6%–32%. An overall prevalence rate of 4% for the general population, the rate in rescue/recovery occupations ranged from 5% to 32%, with the highest rate reported in search and rescue personnel (25%, firefighters (21%, and workers with no prior training for facing disaster. War is one of the most intense stressors known to man. Armed forces have a higher prevalence of depression, anxiety disorders, alcohol abuse and PTSD. High-risk children who have been abused or experienced natural disasters may have an even higher prevalence of PTSD than adults.Female gender, previous psychiatric problem, intensity and nature of exposure to the traumatic event, and lack of social support are known risk factors for work

    Post-stroke language disorders are frequent and include aphasia, alexia, agraphia and acalculia. There are different definitions of aphasias, but the most widely accepted neurologic and/or neuropsychological definition is that aphasia is a loss or impairment of verbal communication, which occurs as a consequence of brain dysfunction. It manifests as impairment of almost all verbal abilities, e.g., abnormal verbal expression, difficulties in understanding spoken or written language, repetition, naming, reading and writing. During the history, many classifications of aphasia syndromes were established. For practical use, classification of aphasias according to fluency, comprehension and abilities of naming it seems to be most suitable (nonfluent aphasias: Broca's, transcortical motor, global and mixed transcortical aphasia; fluent aphasias: anomic, conduction, Wernicke's, transcortical sensory, subcortical aphasia). Aphasia is a common consequence of left hemispheric lesion and most common neuropsychological consequence of stroke, with a prevalence of one-third of all stroke patients in acute phase, although there are reports on even higher figures. Many speech impairments have a tendency of spontaneous recovery. Spontaneous recovery is most remarkable in the first three months after stroke onset. Recovery of aphasias caused by ischemic stroke occurs earlier and it is most intensive in the first two weeks. In aphasias caused by hemorrhagic stroke, spontaneous recovery is slower and occurs from the fourth to the eighth week after stroke. The course and outcome of aphasia depend greatly on the type of aphasia. Regardless of the fact that a significant number of aphasias spontaneously improve, it is necessary to start treatment as soon as possible. The writing and reading disorders in stroke patients (alexias and agraphias) are more frequent than verified on routine examination, not only in less developed but also in large neurologic departments. Alexia is an acquired

    Unexpected extreme sudden traumatic stressor may cause post-traumatic stress disorder (PTSD). Important traumatic events include war, violent personal assault (e.g., sexual assault, and physical attack), being taken hostage or kidnapped, confinement as a prisoner of war, torture, terrorist attack, severe car accidents, and natural disasters. In childhood age sexual abuse or witnessing serious injuries or unexpected death of a beloved one are among important traumatic events.PTSD can be categorized into two types of acute and chronic PTSD: if symptoms persist for less than three months, it is termed "acute PTSD," otherwise, it is called "chronic PTSD." 60.7% of men and 51.2% of women would experience at least one potentially traumatic event in their lifetime. The lifetime prevalence of PTSD is significantly higher in women than men. Lifetime prevalence of PTSD varies from 0.3% in China to 6.1% in New Zealand. The prevalence of PTSD in crime victims are between 19% and 75%; rates as high as 80% have been reported following rape. The prevalence of PTSD among direct victims of disasters was reported to be 30%-40%; the rate in rescue workers was 10%-20%. The prevalence of PTSD among police, fire, and emergency service workers ranged from 6%-32%. An overall prevalence rate of 4% for the general population, the rate in rescue/recovery occupations ranged from 5% to 32%, with the highest rate reported in search and rescue personnel (25%), firefighters (21%), and workers with no prior training for facing disaster. War is one of the most intense stressors known to man. Armed forces have a higher prevalence of depression, anxiety disorders, alcohol abuse and PTSD. High-risk children who have been abused or experienced natural disasters may have an even higher prevalence of PTSD than adults.Female gender, previous psychiatric problem, intensity and nature of exposure to the traumatic event, and lack of social support are known risk factors for work-related PTSD.

    four degraders (one on each engine); and the FAA refined AMK (blending, testing, and fueling a full-size aircraft). The 15 flights had 15 takeoffs, 14 landings and a larger number of approaches to about 150 feet above the prepared crash site under remote control. These flight were used to introduce AMK one step at a time into some of the fuel tanks and engines while monitoring the performance of the engines. On the final flight (No. 15) with no crew, all fuel tanks were filled with a total of 76,000 pounds of AMK and the remotely-piloted aircraft landed on Rogers Dry Lakebed in an area prepared with posts to test the effectiveness of the AMK in a controlled impact. The CID, which some wags called the Crash in the Desert, was spectacular with a large fireball enveloping and burning the B-720 aircraft. From the standpoint of AMK the test was a major set-back, but for NASA Langley, the data collected on crashworthiness was deemed successful and just as important.

    In this in vitro study, properties of a titanium alloy post recently introduced to the market (IntegraPost), were compared with those of a clinically proven stainless steel post (ParaPost). The IntegraPost has a unique, perforated, spherical head and a microknurled shank surface. The posts were tested for rigidity, for retention within the root canals of extracted teeth and for ability to retain composite resin cores. The two post types exhibited similar properties in core and root canal retention, however, the IntegraPost was significantly less rigid than the ParaPost.

  18. Post-communism: postmodernity or modernity revisited?

    Science.gov (United States)

    Ray, L

    1997-12-01

    Coinciding with the popularity of postmodern theory, the fall of communism appeared to offer further evidence of the exhaustion of modernity. Such analysis is grounded in a view that the Soviet system was the epitome of modernity. An alternative approach regards post-communism as opening new terrains of struggle for modernity. Thus Habermas and others suggest that post-communist societies are rejoining the trajectory of western modernity whose problems they now recapitulate. This alternative view implies that Soviet systems were something other than 'modern', although their nature is not always clearly defined. However, even if post-communist societies do encounter problems of modernity, they do so in new circumstances where modernist notions of social development have become problematic. This article argues that, contrary to those who regard modernization or postmodernization as irresistible trends, core post-communist societies are likely to develop along an alternative path to that of western modernity. This is tentatively described as 'neo-mercantilist'.

    Full Text Available Scholars have suggested models proposing a variety of learning styles for humans. Human Dynamics is one such model, and it has been suggested within its model that one style of learning is enhanced by discussion among learners. While this style of learning may be accomplished relatively easily in an on-campus person-to-person situation, it is not clear how a discussion mode (online posts of learning might be accomplished in an online format. A study of more than 9,000 posts from 240 students in 11 different online classes was conducted to determine whether differences in online discussion posts by individuals with different learning styles were evident. Results of the study suggest that discussion post activity, if managed with suitable rubrics and guiding principles, and augmented by appropriate modeling behavior, is an effective teaching mode for all dynamics, but seem to be a more successful learning mode for individuals of Physically Centered dynamics.

    Full Text Available Objective: To investigate the fracture strength and mode of endodontically treated teeth with structurally weakened roots reconstructed with woven polyethylene fiber posts and biological posts. Methods: After removing the crowns, 60 endodontically treated maxillary canines were distributed into 4 groups: 1 conventional root canal preparation and reconstruction with polyethylene fiber posts; 2 conventional root canal preparation and reconstruction with biological posts; 3 moderately flared root canals and reconstruction with biological posts; 4 widely flared root canals and reconstruction with biological posts. The posts were cemented with resin cement Enforce (Dentsply Ind. e Com., Petrópolis, Rio de Janeiro, Brasil and the core was constructed with Ti-Core (EssentialDental Systems, S. Hackensack, NJ, USA resin composite. The specimens were tested under compression in a universal testing machine. Results: The following fracture strength values were obtained: Group 1 – 45.46kgf; Group 2 – 53.30kgf; Group 3 – 58.67kgf; Group 4 – 47.91kgf, with statistically significant differences between Groups 1 and 3 (p<0.05. The following fracture modes were observed: Group 1 – predominance of fracture of the coronal portion of the post; Groups 2 and 3 – various fracture patterns; Group 4 – all roots fractured. Conclusion: Both posts were shown to be promising (adequate fracture strength and favorable pattern of fracture. Biological posts appear to be capable of reinforcing the root to some extent; however, fracture occured in all roots with widely flared root canals.

An unusual cause of failure has been identified, which is the subject of this paper. Microscopy and microanalysis of the fracture surface showed that the failure was due to pre-existing cracks, from the fabrication of the post. This conclusion was reached after detecting and analysing a galvanised layer on the fracture surfaces.

    2009-01-01

    Objectives: The efficacy of user-defined subject tagging and software-generated subject tagging for describing and organizing cancer blog contents was explored. Methods: The Technorati search engine was used to search the blogosphere for cancer blog postings generated during a two-month period. Postings were mined for relevant subject concepts, and blogger-defined tags and Text Analysis Portal for Research (TAPoR) software–defined tags were generated for each message. Descriptive data were collected, and the blogger-defined tags were compared with software-generated tags. Three standard vocabularies (Opinion Templates, Basic Resource, and Medical Subject Headings [MeSH] Resource) were used to assign subject terms to the blogs, with results compared for efficacy in information retrieval. Results: Descriptive data showed that most of the studied cancer blogs (80%) contained fewer than 500 words each. The numbers of blogger-defined tags per posting (M = 4.49 per posting) were significantly smaller than the TAPoR keywords (M = 23.55 per posting). Both blogger-defined subject tags and software-generated subject tags were often overly broad or overly narrow in focus, producing less than effective search results for those seeking to extract information from cancer blogs. Conclusions: Additional exploration into methods for systematically organizing cancer blog postings is necessary if blogs are to become stable and efficacious information resources for cancer patients, friends, families, or providers.

    This study identifies the most common microorganisms present in type III gold cast posts related to pulpal disease and evaluates the sterilization/disinfection method before cementation in the root canal. Forty-five type III gold cast posts were aseptically collected in sterile sealed plastic bags and taken to the microbiology laboratory to carry out the study: fifteen cast posts had no treatment, fifteen were disinfected (immersion in 70% alcohol during 15 minutes), and fifteen were autoclaved at 121°C for 15 minutes by using saturated steam under 15 psi pressure. By using a two-proportion z-test, the difference was statistically significant (p > 0.05) and demonstrates that, in spite of the aseptic pattern used in the cast post collection and laboratory procedures, some cast posts arrive contaminated at the consulting office. The disinfection process worked out in a high percentage and demonstrated that the sterilization by autoclaving eliminated completely the pathogenic microbiota without affecting the cast post shape and integrity that could compromise their final fitting.

  16. Post-translational modifications in neurodegeneration

    Directory of Open Access Journals (Sweden)

    Federico Benetti

    2015-12-01

    Full Text Available Post-translational modifications increase proteome functionality for managing all aspects of normal cell biology. They are based on the covalent attachment of functional groups, leading to phosphorylation, acetylation, glycosylation, acylation, ubiquitination, SUMOylation and oxidation of protein targets. Post-translational modifications occur at any step of protein life cycle, modulating in time and space protein folding, subcellular localization and activity. Aberrant post-translational modifications of one or more culprit proteins may lead to neurodegeneration, as shown in paradigmatic neurological disorders such as Alzheimer’s, Parkinson’s and prion diseases. In this review, we report the most important post-translational modifications found in neurodegenerative disorders, illustrating the pathophysiological mechanisms in which they are involved. This work highlights the lack of a global framework of post-translational modifications in terms of complexity and regulation. Therefore, in the next future many efforts are required to describe the interplay existing between post-translational modifications and their combinatorial patterns on protein targets.

Esta post-naturaleza, que aspira a ser perfecta, inmortal, invulnerable, es totalmente carente de belleza. De hecho, si bien puede haber una estética de lo artificial y también del artefacto, en relación con los objetos, en cambio no puede darse una estética del cuerpo post-humano, debido a que éste se configura como un no-cuerpo y no tiene las características de lo que comúnmente se entiende por belleza (armonía entre materia y forma, reflejo de interioridad, unicidad.

    2007-08-01

    The aim of the study is to evaluate the effect of post silanization on the microtensile bond strength (MTBS) of translucent fiber posts to seven flowable composite resins used as core material. Seventy fiber posts were employed. In half of the posts, silanization was performed with Monobond-S. A cylindrical plastic matrix was placed around the post and filled with different resins: UniFil Flow Experimental, UniFil Low Flow Plus Experimental, Venus Flow, Revolution Formula 2, Point 4 Flowable, X-Flow, and Wave mv. Five posts were bonded per group. After polymerization, two longitudinal cuts were made on two opposite sides of the post at its outermost periphery. Then, each specimen was serially sectioned, obtaining 30-35 beams with 1-mm(2) cross-sectional area. Each beam was tested in tension in an Instron machine at 0.5 mm/min. ANOVA and Student Newman Keuls tests were performed. The different resin composite materials and the post silanization procedure had a significant effect on MTBS. The application of a silane coupling agent increased MTBS of flowable composite resins to translucent posts. X-flow and Point 4 attained the highest MTBS regardless of the silane treatment.

    Full Text Available Aim : To examine the influence of different post-surface treatments on the interfacial strength between epoxy resin-based fiber posts and methacrylate-based resin composites that are employed as core build-up materials. Materials and Methods : Forty clear posts were divided into four groups of 10 each. The different surface treatments used were etching with alkaline potassium permanganate, 10% hydrogen peroxide, 37% phosphoric acid, and silanization alone. After etching and thorough rinsing, a single layer of silane was applied to the post surface. Then the post was placed in a rectangular plastic matrix and core bulid-up was done using Multi Core, a dual cured composite resin. A slab of uniform thickness, with the post in the center and the core build-up composite on either side was created. The specimens were cut so as to obtain microtensile sticks that were loaded in tension at a cross-head speed of 1 mm/min until failure. The statistical analysis was performed using two-way ANOVA and the paired T test for post-hoc comparisons. Results : The results achieved with potassium permanganate had a significant influence on microtensile interfacial bond strength values with the tested material. Conclusion : Surface chemical treatments of the resin phase of fiber posts enhance the silanization efficiency of the quartz fiber phase, so that the adhesion in the post/core unit may be considered as a net sum of chemical and micromechanical retention.

  20. Post-Colonial Theory and Action Research

    Directory of Open Access Journals (Sweden)

    Jim B. Parsons

    2011-04-01

    Full Text Available This essay explores connections between post-colonial theory and action research. Post-colonial theory is committed to addressing the plague of colonialism. Action research, at its core, promises to problematize uncontested ‘colonial’ hegemonies of any form. Both post-colonial theory and action research engage dialogic, critically reflective and collaborative values to offer a fuller range of human wisdom. The authors contend that post-colonialism theory calls for justice and seeks to speak to social and psychological suffering, exploitation, violence and enslavement done to the powerless victims of colonization around the world by challenging the superiority of dominant perspectives and seeking to re-position and empower the marginalized and subordinated. In similar ways, action research works to eradicate oppression, powerlessness and worthlessness by affirming solidarity with the oppressed, helping humans move from passive to active and by fundamentally reshaping power. Because both post-colonial theory and action research position the insider or oppressed in an ethic of efficacy, it values community, relationships, communication and equality, and is committed to reciprocity, reflexivity and reflection. Thus, both hold the potential to help reconstruct conditions for a more democratic and just society.

  1. Post-insemination sexual selection in birds.

    Science.gov (United States)

    Pizzari, Tommaso

    2007-01-01

    In many avian species females obtain sperm from multiple males during a single reproductive event, setting the scene for post-insemination sexual selection through the competition of the ejaculates of different males over fertilisation (sperm competition) and female biased utilisation of sperm (cryptic female choice). The use of poultry techniques in combination with molecular tools is catalysing an interest in birds as vertebrate model systems to study the mechanisms of post-insemination sexual selection. This chapter: (i) outlines the main mechanisms of avian sperm competition, (ii) introduces methodological approaches to study post-insemination sexual selection in birds, (iii) reviews recent evidence of multiple mechanisms of strategic sperm allocation by males, and (iv) discusses mechanisms of cryptic female choice. Post-insemination variance in paternity in birds, appears to be determined by the interactions between complex male and female strategies of differential sperm utilisation. It is argued that a better understanding of the operation of post-insemination sexual selection in birds may be achieved through a two-pronged approach which, on the one hand, investigates behavioural and physiological mechanisms applying poultry techniques and molecular tools to domestic model species, and on the other, verifies these mechanisms and tests their adaptive significance in more natural populations.

We collected 417,561 Instagram posts with marijuana-related hashtags from November 29 to December 12, 2014. We assessed content of a random sample (n = 5000) of these posts with marijuana-related hashtags. Approximately 2136 (43 %) were explicit about marijuana and further analyzed. Of the 2136 marijuana-related posts, images of marijuana were common (n = 1568). Among these 1568 marijuana images, traditional forms (i.e., buds/leaves) were the most common (63 %), followed by some novel forms of marijuana, including marijuana concentrates (20 %). Among the 568 posts that displayed marijuana being ingested, 20 % showed someone dabbing marijuana concentrates. Marijuana-related advertisements were also observed among the 2136 marijuana-related posts (9 %). Our findings signal the promotion of marijuana use in its traditional plant-based form; trendy and novel modes of marijuana ingestion were also endorsed. This content along with the explicit marketing of marijuana that we observed on Instagram have potential to influence social norms surrounding marijuana use.

    Manchado, A; Villaver, E; de Massas, J Guironnet

    2011-01-01

    We present a complete study of the morphology of post-Asymptotic Giant Branch (AGB) stars. Post-AGB is a very short evolutionary phase between the end of the AGB and the beginning of the Planetary Nebula (PN) stage (between 100 and 10,000 yrs). We have defined the end of the post-AGB phase and the beginning of the PN phase when the star is hot enough to fully ionize the hydrogen envelope. Post-AGB stars have a circumstellar shell that is illuminated by the central stars or partially ionized. However, this circumstellar shell is too small to be resolved from ground-based observations. Thus, we have used data from the Hubble Space Telescope (HST) database to resolve these shells. About 150 post-AGB were found in this database. Here we present the preliminary results on their morphological classification and the correlation with several parameters such as galactic latitude and IRAS fluxes. Our preliminary results show that 40% of the sample are stellar-like (S), 33 % bipolar (B), 12 % multi-polar (M) and 15 % el...

    Full Text Available To determine the risk factors, course of hospital stay and mortality rate among women with post-partum acute kidney injury (AKI, we studied (of 752 patients with AKI admitted to a tertiary care center during the study period between November 2009 and August 2012 27 (3.59% women with post-partum AKI. The data regarding age, parity, cause of renal failure, course of hospital stay and requirement of dialysis were recorded. Sepsis was the major cause (70.3% of post-partum AKI. Other causes included disseminated intravascular coagulation (55.5%, pre-eclampsia/eclampsia (40.7%, ante- and post-partum hemorrhage (40.7% and 22.2% and hemolytic anemia and elevated liver enzymes and low platelet count syndrome (29.6%; most patients had more than one cause of AKI. We found a very high prevalence (18.5% of cortical necrosis in our study patients. A significant correlation was also found between the creatinine level on admission and the period of onset of disease after delivery. In conclusion, several factors are involved in causing post-partum AKI in our population, and sepsis was the most common of them.

    Full Text Available Introduction: Decision for cesarean section may lead to the stress for women in delivery. Stress response requires longer recovery time in post cesarean section patients. Most of patients who experience stress before and after surgical is associated with wound healing delay. When this condition continues, the wound will have a higher risk of infection. The objective of this study was to analyze correlation between stress and wound healing phase in post cesarean section patients. Method: A cross sectional design was used in this study. The population were women with cesarean section, both elective or emergency, in Delivery Room I RSU Dr. Soetomo Surabaya. Samples were recruited by using purposive sampling, with 28 samples who met to the inclusion criterias. The observed variables were stress and wound healing phase in post cesarean section patient. Stress data were collected by interview and wound healing measurement done by observation on the 3rd day post cesarean section. Result: The result showed that women with stress experience wound healing delay. The characteristic of wound healing delay was prolonged on inflammation phase, nevertheless there was presence of granulation tissue. Spearman’s rho correlation showed that correlation value r=0.675 with p=0.000. Discussion: It can be concluded that there was strong significant correlation between stress and wound healing phase in post cesarean section patients. It is important to give this information to the patients with cesarean section in order to prevent stress and delay in wound healing phase.

    Lynch, Michael

    2017-08-01

    This essay takes up a series of questions about the connection between 'symmetry' in Science and Technology Studies (STS) and 'post-truth' in contemporary politics. A recent editorial in this journal by Sergio Sismondo argues that current discussions of 'post-truth' have little to do with conceptions of 'symmetry' or with concerns about 'epistemic democracy' in STS, while others, such as Steve Fuller and Harry Collins, insist that there are such connections. The present essay discusses a series of questions about the meaning of 'post-truth' and 'symmetry', and the connections of those concepts to each other and to 'epistemic democracy'. The essay ends with a series of other questions about STS and contemporary politics, and an invitation to further discussions.

  10. Adolf Hitler had post-encephalitic Parkinsonism.

    Science.gov (United States)

    Lieberman, A

    1996-04-01

    Adolf Hitler had Parkinson symptoms in 1934, at age 45 years. He may have had transient symptoms in 1923, at age 34 years. Young-onset parkinsonism, during the 1920s, favored a diagnosis of post-encephalitic rather than idiopathic parkinsonism. Hitler had oculogyric crises, phenomena only associated with post-encephalitic parkinsonism. In addition, he had dystonic facial spasms, palilalia and a sleep disorder, phenomena more likely to be associated with post-encephalitic than idiopathic parkinsonism. In November 1918, at age 29 years, Hitler may have had von Economo's encephalitis, while he was a patient in a hospital, recovering from poison gas. This paper looks at the possible relationship of von Economo's encephalitis to Hitler's asocial behavior; his obsessions and compulsions, his cruelty and rages. The influence of Hitler's parkinsonism on his conduct during World War II is discussed.

    2015-10-01

    Full Text Available Translucency of dental ceramics, esthetic posts and orthodontic brackets was reviewed. Translucency parameter (TP and contrast ratio (CR are generally used for translucency evaluation. For the evaluation of translucency, two criteria such as the translucency of human teeth (TP = 15–19, 1 mm thick and the visual perceptibility threshold for the translucency difference (∆CR > 0.07 or ∆TP > 2 were used. In ceramics, translucency differences were in the perceptible range depending on the type of material and the thickness. However, variations caused by the difference in the required thickness for each layer by the material and also by the measurement protocols should be considered. As to the translucency of esthetic posts, a significant difference was found among the post systems. Translucency was influenced by the bracket composition and brand, and the differences by the brand were visually perceptible.

    The post-Newtonian scheme in multiple systems with post-Newtonian parameters presented by Klioner and Soffel is extended to the post-post-Newtonian (PPN) order for light propagation problem in the solar system. Under considering the solar system experiment requirement, a new parameter e is introduced. This extension does not change the virtue of the scheme on the linear partial differential equations of the potential and vector potential mentioned in previous work. Furthermore, this extension is based on the former work done by Richter and Matzner in one global system theory. As an application, we also consider the deflection of light ray in the global coordinates. And the deflection angle of light ray is obtained with post-Newtonian parameters.

  20. The effect of friction in the hold down post spherical bearings on hold down post loads

    Science.gov (United States)

    Richardson, James A.

    1990-01-01

    The effect of friction at the connection of the Solid Rocket Booster (SRB) aft skirt and the mobile launch platform (MLP) hold down posts was analyzed. A simplified model of the shuttle response during the Space Shuttle Main Engine (SSME) buildup was constructed. The model included the effect of stick-slip friction for the rotation of the skirt about the spherical bearing. Current finite element models assume the joint is completely frictionless in rotation and therefore no moment is transferred between the skirt and the hold down posts. The model was partially verified against test data and preliminary parameter studies were performed. The parameter studies indicated that the coefficient of friction strongly influenced the moment on the hold down posts. The coefficient of friction had little effect on hold down post vertical loads, however. Further calibration of the model is necessary before the effect of friction on the hold down post horizontal loads can be analyzed.

    Science.gov (United States)

    Morax, S; Baudoin, F; Hurbli, T

    1995-12-01

    Post-traumatic ptosis may be classified as follows: ptosis occurring during lid avulsion, ptosis associated with fractures of the orbital roof and with foreign bodies, post-contusional ptosis, cicatricial ptosis, neurogenic ptosis and post-surgical ptosis. The patient must be thoroughly examined, including examination of the eye-ball, extra-ocular muscles, eyelid and evaluation of upper eyelid levator function and orbital and facial examination. The various surgical methods proposed include levator muscle surgery, aponeurotic surgery, Müller's muscle surgery and frontalis suspension surgery. Surgical indications and choice of surgical method essentially depend on the anatomo-clinical forms. The general rule is to operate under local anesthesia to obtain better control of the muscular function. Some cases are simple to treat such as post-contusional ptosis with good levator function which allows functional surgery with excellent static and dynamic results. Other relatively simple cases with non functional levators may only be treated on a static basis. Last but not least are more difficult cases in which levator function is difficult to evaluate pre-operatively because of severe fibrosis. The aim in such cases is to explore the eyelid by an anterior approach under local anesthesia and to propose either muscular surgery or a frontalis suspension according to the anatomical and functional status of the levator muscle.

  13. Post stapedotomy aviation: A changing scenario.

    Science.gov (United States)

    Rajguru, Renu

    2014-01-01

    Aeromedical implications of stapedotomy like rapid barometric changes and G forces are generally thought to put an end to the aviation career of an aviator. Aviation industry has grown tremendously in the last few decades, and aviation now is not only occupational but also recreational. The Indian Military Aviation rules state that, "Stapedectomy cases will be assessed permanently unfit for flying duties. These cases will be cautioned against flying in an unpressurised aircraft." The basis of this is the aeromedical concerns associated with stapedotomy as clinical conditions which are of minor significance on the ground may become aggravated in the air. With an ever expanding civil and military aviation industry, the number of aviators who have undergone stapedotomy has also increased. Though grounding the aircrew is the safest option, but if medical certification is denied to all, then the majority who can fly safely will also be excluded, thus denying the organization of its trained resources. This paper discusses post otosclerosis and post stapedotomy aeromedical concerns, reviews existing literature concerning post stapedotomy aviation and various post stapedotomy aviation policies.

    Directory of Open Access Journals (Sweden)

    Marieke Liem

    2014-12-01

    Full Text Available Previous research suggests that social relations, in particular the forming of family ties and employment (social factors, self-efficacy (personal factors, and therapeutic interventions (institutional factors constitute main contributors in post-release success. These studies, however, have largely been based on general delinquents serving relatively short prison terms. This study aims to shed light on the influence of social, personal, and institutional factors on post-release success versus failure among paroled lifers. We conducted in-depth life-history interviews with 64 individuals who had served a life sentence, who were either re-incarcerated for another crime or parole violation, or were currently out on parole. The role of social factors in desistance among long-term incarcerated offenders was minimal. Rather, self-efficacy appeared to be a key element in post-release success. These findings suggest that research based on short-term incarcerated offenders cannot be directly translated to long-term incarcerated offenders. This group does not experience the same traditional turning points, such as establishing family ties and employment. Accordingly, long-term prisoners may go through a different process post-release that determines their success versus failure compared to general delinquents who serve shorter sentences.

With an ever expanding civil and military aviation industry, the number of aviators who have undergone stapedotomy has also increased. Though grounding the aircrew is the safest option, but if medical certification is denied to all, then the majority who can fly safely will also be excluded, thus denying the organization of its trained resources. This paper discusses post otosclerosis and post stapedotomy aeromedical concerns, reviews existing literature concerning post stapedotomy aviation and various post stapedotomy aviation policies.

    Considerable developments have occurred in meniscal surgery, and consequently in the imaging of post-operative menisci, over the last 15 years. A drive to preserve meniscal physiologic function for as long as possible, in order to delay osteoarthrosis, has resulted in limited partial meniscectomies, meniscal repairs and meniscal transplants. Each of these techniques affects the imaging appearance of the meniscus, reducing the accuracy of conventional MRI in predicting recurrent tears. The specificity of conventional MRI can be improved by employing at least two T2-weighted sequences, but this still leaves a shortfall in sensitivity. In an attempt to increase the diagnostic accuracy of cross-sectional imaging, MR arthrography (MRA) and CT arthrography (CTA), have been applied to the post-operative meniscus. Sensitivities and specificities for these two techniques approach 90% in predicting recurrent meniscal tears. In the setting of clinical symptoms and gross meniscal deficiency, meniscal allografts are being transplanted with increasing frequency. In these transplants meniscal degeneration, fragmentation and separation are common findings, but the role of imaging in the management of these patients has not yet been well defined. This review explores the imaging techniques available for the evaluation of the post-operative meniscus, their strengths and weaknesses, and the reasons that they may find a place in a rational strategy for imaging of the symptomatic post-operative knee.

    This in vitro study evaluated the effect of presence of post, presence of core, and of shape, type, and surface treatment of posts on resistance to cyclic loading of crowned human teeth. For all teeth, crowns designed without ferrule were cast in sterling silver and luted with resin cement (Panavia...... F). Each tooth underwent cyclic loading of 600 N at two loads per second until failure. Teeth that had only been crowned showed significantly higher resistance to cyclic loading than teeth with cores or with post and cores. No significant differences were found between teeth restored with cores only...... or with post and cores, irrespective of surface-treatment of the posts. Teeth restored with parallel-sided cast post (ParaPost XP) and cores showed significantly higher resistance to cyclic loading than teeth with either tapered cast posts or untreated prefabricated posts of titanium alloy (ParaPost XH...

  13. Context specificity of post-error and post-conflict cognitive control adjustments.

    Directory of Open Access Journals (Sweden)

    Sarah E Forster

    Full Text Available There has been accumulating evidence that cognitive control can be adaptively regulated by monitoring for processing conflict as an index of online control demands. However, it is not yet known whether top-down control mechanisms respond to processing conflict in a manner specific to the operative task context or confer a more generalized benefit. While previous studies have examined the taskset-specificity of conflict adaptation effects, yielding inconsistent results, control-related performance adjustments following errors have been largely overlooked. This gap in the literature underscores recent debate as to whether post-error performance represents a strategic, control-mediated mechanism or a nonstrategic consequence of attentional orienting. In the present study, evidence of generalized control following both high conflict correct trials and errors was explored in a task-switching paradigm. Conflict adaptation effects were not found to generalize across tasksets, despite a shared response set. In contrast, post-error slowing effects were found to extend to the inactive taskset and were predictive of enhanced post-error accuracy. In addition, post-error performance adjustments were found to persist for several trials and across multiple task switches, a finding inconsistent with attentional orienting accounts of post-error slowing. These findings indicate that error-related control adjustments confer a generalized performance benefit and suggest dissociable mechanisms of post-conflict and post-error control.

  14. Cryptococcal meningitis post autologous stem cell transplantation.

    2014-06-01

    Disseminated Cryptococcus disease occurs in patients with defective T-cell immunity. Cryptococcal meningitis following autologous stem cell transplant (SCT) has been described previously in only 1 patient, 4 months post SCT and while off antifungal prophylaxis. We present a unique case of Cryptococcus meningitis pre-engraftment after autologous SCT, while the patient was receiving fluconazole prophylaxis. A 41-year-old man with non-Hodgkin's lymphoma underwent autologous SCT. Post-transplant prophylaxis consisted of fluconazole 400 mg daily, levofloxacin 500 mg daily, and acyclovir 800 mg twice daily. On day 9 post transplant, he developed fever and headache. Peripheral white blood cell count (WBC) was 700/μL. Magnetic resonance imaging of the brain showed lesions consistent with meningoencephalitis. Cerebrospinal fluid (CSF) analysis revealed a WBC of 39 with 77% lymphocytes, protein 63, glucose 38, CSF pressure 20.5 cmH2 O, and a positive cryptococcal antigen. CSF culture confirmed Cryptococcus neoformans. The patient was treated with liposomal amphotericin B 5 mg/kg intravenously daily, and flucytosine 37.5 mg/kg orally every 6 h. He was switched to fluconazole 400 mg daily after 3 weeks of amphotericin therapy, with sterilization of the CSF with negative CSFCryptococcus antigen and negative CSF culture. Review of the literature revealed 9 cases of cryptococcal disease in recipients of SCT. Median time of onset was 64 days post transplant. Only 3 meningitis cases were described; 2 of them after allogeneic SCT. Fungal prophylaxis with fluconazole post autologous SCT is recommended at least through engraftment, and for up to 100 days in high-risk patients. A high index of suspicion is needed to diagnose and treat opportunistic infections, especially in the face of immunosuppression and despite adequate prophylaxis. Infection is usually fatal without treatment, thus prompt diagnosis and therapy might be life saving.

  18. Disability and the post-2015 development agenda.

    Science.gov (United States)

    Tardi, Rachele; Njelesani, Janet

    2015-01-01

    The article considers the extent to which disability has been recognized and included in two main documents produced to date as part of the United Nations Post-2015 Development agenda process. This is the process that is defining the Sustainable Development Goals (SDGs), which will succeed the UN Millennium Development Goals (MDGs) after the latter reach their target date in 2015. The two documents examined in the article are the Outcome Document (July 2014) of the Open Working Group (OWG) on SDGs and the Report (August 2014) of the Intergovernmental Committee of Experts on Sustainable Development Financing (ICESDF). The OWG consisted of 30 seats shared by 70 UN Member States and was in charge of proposing goals and targets for the SDGs. The ICESDF worked in parallel to the OWG and its report proposed options on an effective financing strategy. The article emphasizes the importance of including persons with disabilities in the Post-2015 Agenda, especially in view of the latter's overarching focus on eradicating poverty. The inclusion of persons with disabilities is being recognized in the Post-2015 Agenda discussions as central to achieving sustainable development. Disability has been explicitly mentioned in the OWG and ICESDF documents. Although the results so far have been very good, more work still needs to be done to ensure that these explicit references are maintained in the final version of the SDGs, which will be adopted in September 2015. Furthermore, the new framework needs to have a stronger human rights foundation on which to ground these references and future indicators. Light for the World is an international confederation of national development non-governmental organizations (NGOs) aiming at an inclusive society, where the rights of persons with disabilities are realized without discrimination. Through a rights-based approach, Light for the World supports 175 programs in 25 countries in the areas of prevention of blindness, rehabilitation, inclusive

    Bhatt, Shantanu; Romeo, Tony; Kalman, Daniel

    2011-05-01

    Bacteria evolve their capacity to cause disease by acquiring virulence genes that are usually clustered in discrete genetic modules termed pathogenicity islands (PAI). Stable integration of PAIs into pre-existing transcriptional networks coordinates expression from PAIs with ancestral genes in response to diverse environmental cues. Such transcriptional controls are evident in the regulation of the locus of enterocyte effacement (LEE), a PAI of enteropathogenic and enterohemorrhagic Escherichia coli. However, recent reports indicate that global post-transcriptional and post-translational regulators, including CsrA, Hfq and ClpXP, fine-tune the transcriptional output from the LEE. In this opinion article, we highlight recent advances in the understanding of post-transcriptional and post-translational regulation in attaching and effacing pathogens.

    Vanin, Stefano; Zancaner, Silvano

    2011-10-10

    Postmortem animal feeding activity may cause considerable damage to bodies resulting in the modification of wounds, loss of identifying features and injury. Certain postmortem lesions may appear inflicted or non-inflicted antemortem injuries. At present, apart from cases in sea water, no data are available about post mortal lesions performed by aquatic organisms. This note that represents the first report concerning colonisation of a dead body by crustaceans a few hours after death, describes injuries caused by the amphipod Niphargus elegans on the face, and in particular on the eye region, of a young man dead by drowning. The lesions recorded in this case are comparable with the lesions caused by ants. The high plasticity in the food choice can allow Amphipoda to colonise drowning bodies in every moment after dead, however the benthonic behaviour of these animals suggests a more important role in the colonisation during post-mortem submersion periods.

  2. Alternative solvents for post combustion carbon capture

    2013-01-01

    Full Text Available The process model of post combustion chemical absorption is developed in Aspen Plus for both coal and gas fired power plant flue gas treating. The re-boiler energy requirement is considered as the most important factor to be optimized. Two types of solvents, mono-ethylamine (MEA and di-ethylamine (DEA, are used to implement the model for three different efficiencies. The re-boiler energy requirement for regeneration process is calculated. Temperature and concentration profiles in absorption column are analyzed to understand the model behavior. Re-boiler energy requirement is considerably lower for DEA than MEA as well as impact of corrosion also less in DEA. Therefore, DEA can be recommended as a better solvent for post combustion process for carbon capture plants in fossil fuel fired power industries.

    2015-05-01

    Full Text Available Superior mesenteric artery (SMA syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Loss of fatty tissue as a result of a variet y of debilitating conditions is believed to be the etiologic factor causing the acute angulation. Conditions like increased spinal lordosis, application of a body cast, short ligament of Treitz or unusually low origin of SMA may also precipitate this syndr ome. The diagnosis of SMA syndrome is based on clinical symptoms and radiologic evidence of obstruction. SMA syndrome has been described after rapid or severe weight loss in conditions such as cancer or extensive burn injuries, prolonged bed rest, anorexia , or malabsorption syndromes. Herewith we are reporting a case of post pancreatitis SMA syndrome. KEYWORDS: Post pancreatitis SMA syndrome; superior mesenteric artery syndrome; SMA syndrome.

  5. New Post-Collision Line Design

    Gatignon, Lau

    2014-01-01

    The 1.5 TeV Compact Linear Collider (CLIC) beams, with a total power of 14 MW per beam, are disrupted at the interaction point due to the very strong beam-beam effect. As a result, some 3.5 MW reach each main dump in form of beamstrahlung photons. About 0.5 MW of e+e- pairs with a very broad energy spectrum need to be disposed of along the post-collision line while separating the various beams by charge for beam diagnostics purposes. The Post-collision line has been optimised in order to reduce radiation damage to magnets, the number of magnets required and the stray fields to the incoming beam line.

    Ellis, John; Nanopoulos, Dimitri V; Olive, Keith A; Peloso, Marco

    2016-01-01

    We revisit gravitino production following inflation. As a first step, we review the standard calculation of gravitino production in the thermal plasma formed at the end of post-inflationary reheating when the inflaton has completely decayed. Next we consider gravitino production prior to the completion of reheating, assuming that the inflaton decay products thermalize instantaneously while they are still dilute. We then argue that instantaneous thermalization is in general a good approximation, and also show that the contribution of non-thermal gravitino production via the collisions of inflaton decay products prior to thermalization is relatively small. Our final estimate of the gravitino-to-entropy ratio is approximated well by a standard calculation of gravitino production in the post-inflationary thermal plasma assuming total instantaneous decay and thermalization at a time $t \\simeq 1.2/\\Gamma_\\phi$. Finally, in light of our calculations, we consider potential implications of upper limits on the gravitin...

    The 1.5 TeV CLIC beams, with a total power of 14 MW per beam, are disrupted at the interaction point due to the very strong beam-beam effect. As a result, some 3.5 MW reach the main dump in form of beamstrahlung photons. About 0.5 MW of e+e- pairs with a very broad energy spectrum need to be disposed of along the post-collision line. The conceptual design of this beam line will be presented. Emphasis will be on the optimization studies of the CLIC post-collision line design with respect to the energy deposition in windows, dumps and absorbers, on the design of the luminosity monitoring for a fast feedback to the beam steering and on the background conditions for the luminosity monitoring equipment.

    2011-01-01

    The CLIC post collision line is designed to transport the un-collided beams and the products of the collided beams with a total power of 14MW to the main beam dump. Full Monte Carlo simulation has been done for the description of the CLIC luminosity monitoring in the post collision line. One method of the luminosity diagnostic is based on the detection of high energy muons produced by beamstrahlung photons in the main beam dump. The disrupted beam and the beamstrahlung photons produce at the order of 106 muons per bunch crossing per cm2, with energies higher than 10 GeV. Threshold Cherenkov counters are considered after the beam dump for the detection of these high energy muons. Another method for luminosity monitoring is presented using the direct detection of the beamstrahlung photons.

    1985-02-09

    Seven cases of hypothyroidism developed within 6 months of delivery are reported. Radioimmunoassays regularly showed very low thyroxin levels and high thyroid-stimulating hormone levels, thus confirming that the thyroid deficiency was of peripheral origin. A significant rise in antimicrosomial or antithyroglobulin antibodies was noted in 5 cases. One patient had HLA-B8 and 4 had HLA-DR3, which was not significantly different from the prevalence in the regional population. In contrast with the transient post-partum hypothyroidism reported mainly in Japan, the condition proved to be permanent in 6 patients followed up for more than two years. The increased frequency of HLA-DR3 and 5 recently described in thyroiditis with transient post-partum thyrotoxicosis was not found in our series. It would appear that pregnancy, which is a period of immune incompetence, may disclose a latent lymphocytic thyroiditis.

    Olaf Voolstra

    2014-04-01

    Full Text Available Transient receptor potential (TRP channels constitute an ancient family of cation channels that have been found in many eukaryotic organisms from yeast to human. TRP channels exert a multitude of physiological functions ranging from Ca2+ homeostasis in the kidney to pain reception and vision. These channels are activated by a wide range of stimuli and undergo covalent post-translational modifications that affect and modulate their subcellular targeting, their biophysical properties, or channel gating. These modifications include N-linked glycosylation, protein phosphorylation, and covalent attachment of chemicals that reversibly bind to specific cysteine residues. The latter modification represents an unusual activation mechanism of ligand-gated ion channels that is in contrast to the lock-and-key paradigm of receptor activation by its agonists. In this review, we summarize the post-translational modifications identified on TRP channels and, when available, explain their physiological role.

    1989-08-01

    When you suspect that you just gave an erroneous answer to a question you stop and rethink. Suspected errors lead to a shift in the control and content of cognitive processes. In the present experiment we investigated the influence of errors upon heart rates and response latencies. Sixty-four subjects participated in an experiment in which each subject solved a sequence of 60 verbal analogies. The results demonstrated increased latencies after errors and decelerated heart rates during the post-error period. The results were explained by a psychophysiological model in which the septo-hippocampal system functions as a control system which coordinates the priority and selection of cognitive processes. Error detection suppresses strategies which otherwise prevent looping and iterative reanalyses of old material. The inhibition is also responsible for the cardiac slowing during the post-error period.

    Framing the special issue on the transformation of Food and Agricultural Policy, this article introduces the concept of post-exceptionalism in public policies. The analysis of change in agri-food policy serves as a generative example to conceptualize current transformations in sectoral policy...... arrangements in democratic welfare states. Often these arrangements have been characterized by an exceptionalist ideational framework that legitimizes a sector’s special treatment through compartmentalized, exclusive and producer-centered policies and politics. In times of internationalization of policy......-making, increasing interlinkage of policy areas and trends towards self-regulation, liberalization and performance-based policies, policy exceptionalism is under pressure to either transform or give way to (neo-)liberal policy arrangements. Post-exceptionalism denotes a partial transformation of exceptionalist ideas...

    2013-01-01

    Full Text Available An 83-year-old male presented with dyspnoea and stridor. He had undergone pneumonectomy 40 years ago. CT scan revealed gross shift of mediastinum (post-pneumonectomy syndrome with tortuous trachea kinked at the thoracic inlet. Fibre optic bronchoscopy showed a near total expiratory closure of trachea, right main bronchus, and segmental bronchi confirming tracheobronchomalacia. He was managed with long length, low tracheostomy in view of his poor general condition of permitting more invasive procedures. He showed adequate clinical improvement and was discharged home. Tracheobronchomalacia in post-pneumonectomy syndrome requires emergent management. Its occurrence after 40 years is very rare and may be easily missed. It can be diagnosed with dynamic CT and FOB. Although invasive management with stenting or surgical methods is routinely advised, conservative care can be effective in selected cases.

  17. The LHC Post-mortem System

    CERN Document Server

    Ciapala, Edmond; Schmidt, R; Wenninger, J

    2002-01-01

    The energy stored in the beam and the magnets of the LHC is of unprecedented scale compared to other existing accelerators. The LHC machine is protected from an uncontrolled release of this energy by a large number of interlock channels. The LHC machine interlock system manages the interlock conditions and has as main task to trigger safe extraction of the energy stored in the electrical circuits and in the beams. To operate the machine in the presence of such a large interlock system requires powerful diagnostics to trace back the origin of power and beam related problems. This diagnostics tool, called herein the post-mortem system, has the role of organizing the collection and analysis of transient data recorded around a beam or power abort by all relevant LHC equipment systems. A first conceptual design of the LHC post-mortem system is presented in this document together with the main requirements for the LHC equipment systems.

    Full Text Available Background: Post-operatory pain is a spread and constant problem during the care of the surgical patient. The tendency to find new therapeutic techniques to alleviate pain has lead scientists to make and use a great variety of analgesics which are administered by different vias. The effects of narcotics on the new born are well known and the author´s worries about this problem has been the motivational point to search about the use of epidural and intratecal narcotics in the obstetric patient. Objective: To assess the use of peridural liophilized morphine in the Caesarean Section Method: A study of a series of cases was carried out at the Surgical Unit of the Gynecobstetric service of the University Hospital ¨Dr. Gustavo Aldereguía Lima¨ from February 2001 to August 2002 . This search included 120 patient who were selected to elective iterative caesarean section The variables under study were blood pressure, pulse and respiration during the pre- trans and post operative phases, onset of the anaesthetic effect and its duration, peri operatory complications , quality of the post operatory analgesia and its effect on the newborn measured by using Apgar values . The statistical procedure was developed by using the statistical package Epi Info 6. Results: The onset of the anesthetic effect and the duration of the anesthesia were not modified with the use of liophilized morphine. Vital signs remained within normal limits in most of the patients during the pre- trans and post operatory phases. The complications were: pruritus, urinary retention, nausea nad vomiting. The quality of the analgesia was satisfactory in most of the patients. The Apgar values were normal in all neonates. Conclusion: The administration of peridural liophilized morphine in elective caesarean sections is a reliable, sure and useful method in our environment.

    The post-coital insertion of IUDs is a proposed test to be undertaken at the Marie Stopes Clinic in London. The assumption is that within five days of unprotected intercourse the IUD acts as a means of preventing implantation of an egg in the event of fertilization. Researchers feel that by this method it would be possible to eliminate the trauma of abortion in unwanted pregnancies and to alleviate the anxiety of rape victims.

    In countries where induced abortions are legal and medically supervised, the frequency of post-abortion infections is low and maternal death is infrequent. Nevertheless, short and long term consequences of post-abortion infections must be addressed. Sexually transmitted pathogens are frequently in cause here. Risk factors include in particular young age (less than 24 years), low socioeconomic level, late pregnancy, nulliparity, and history of previous untreated pelvic inflammatory disease. Diagnosis is based on clinical criteria and an inflammatory syndrome occurring within 2 to 3 weeks after spontaneous or induced abortion. A pelvic ultrasound is recommended in order to ensure the uterus vacuity and to look for a possible pelvic abscess, and bacteriological samples must be performed. Management consists in a regimen combining two antibiotics intravenously, with the possible addition of intravenous heparin in case of pelvic thrombophlebitis. Antibiotics can be discontinued 48 h of a clinical improvement and further treatment by oral route brings no benefit. Intrauterine retention associated with post-abortion endometritis must be addressed either by medical or surgical method.

  12. Does Post Septoplasty Nasal Packing Reduce Complications?

    Directory of Open Access Journals (Sweden)

    Bijan Naghibzadeh

    2011-01-01

    Full Text Available The main issues in nasal surgery are to stabilize the nose in the good position after surgery and preserve the cartilages and bones in the favorable situation and reduce the risk of deviation recurrence. Also it is necessary to avoid the synechia formation, nasal valve narrowing, hematoma and bleeding. Due to the above mentioned problems and in order to solve and minimize them nasal packing, nasal splint and nasal mold have been advised. Patients for whom the nasal packing used may faced to some problems like naso-pulmonary reflex, intractable pain, sleep disorder, post operation infection and very dangerous complication like toxic shock syndrome. We have two groups of patients and three surgeons (one of the surgeons used post operative nasal packing in his patients and the two others surgeons did not.Complications and morbidities were compared in these two groups. Comparing the two groups showed that the rate of complication and morbidities between these two groups were same and the differences were not valuable, except the pain and discomfort post operatively and at the time of its removal. Nasal packing has several risks for the patients while its effects are not studied. Septoplasty can be safely performed without postoperative nasal packing. Nasal packing had no main findings that compensated its usage. Septal suture is one of the procedures that can be used as alternative method to nasal packing. Therefore the nasal packing after septoplasty should be reserved for the patients with increased risk of bleeding.

    Full Text Available Post-renal transplant de-novo inflammatory bowel disease (IBD may develop despite the presence of mycophenolate mofetil (MMF, a drug used for treatment of IBD, in the immunosuppressive regimen. A 39-year-old man received live unrelated renal transplant, and was started postoperatively on prednisolone, MMF, and tacrolimus, which was changed to sirolimus when he developed diabetes mellitus two months post-transplant. Nine months post-transplant, the patient developed recurrent attacks of bloody diarrhea and ischio-rectal abscesses complicated by anal fistulae not responding to routine surgical treatment. Colonoscopy diagnosed IBD, a Crohn′s disease-like pattern. The patient was treated with steroids and 5-aminosalicylic acid (5-ASA in addition to a two months course of ciprofloxacin and metronidazole. He became asymptomatic and rectal lesions healed within one month of treatment. The patient continued to be asymptomatic, and he maintained normal graft function on the same immunosuppressive treatment in addition to 5-ASA. We conclude that de-novo IBD disease can develop in renal transplant recipients in spite of immunosuppressive therapy including MMF.

  15. Historical approaches to post-combat disorders.

    Science.gov (United States)

    Jones, Edgar

    2006-04-29

    Almost every major war in the last century involving western nations has seen combatants diagnosed with a form of post-combat disorder. Some took a psychological form (exhaustion, combat fatigue, combat stress reaction and post-traumatic stress disorder), while others were characterized by medically unexplained symptoms (soldier's heart, effort syndrome, shell shock, non-ulcer dyspepsia, effects of Agent Orange and Gulf War Syndrome). Although many of these disorders have common symptoms, the explanations attached to them showed considerable diversity often reflected in the labels themselves. These causal hypotheses ranged from the effects of climate, compressive forces released by shell explosions, side effects of vaccinations, changes in diet, toxic effects of organophosphates, oil-well fires or depleted-uranium munitions. Military history suggests that these disorders, which coexisted in the civilian population, reflected popular health fears and emerged in the gaps left by the advance of medical science. While the current Iraq conflict has yet to produce a syndrome typified by medically unexplained symptoms, it is unlikely that we have seen the last of post-combat disorders as past experience suggests that they have the capacity to catch both military planners and doctors by surprise.

    2014-01-01

    Industry has an increasing interest in the use of enzymes as environmentally friendly, highly efficient, and specific bio-catalysts. Enzymes have primarily evolved to function in aqueous environments at ambient temperature and pressure. These conditions however do not always correspond with industrial processes or applications, and only a small portion of all known enzymes are therefore suitable for industrial use. Protein engineering can sometimes be applied to convey more desirable properties to enzymes, such as increased stability, but is limited to the 20 naturally occurring amino acids or homologs thereof. Using post-production modification, which has the potential to combine desirable properties from the enzyme and the conjugated compounds, enzymes can be modified with both natural and synthetic molecules. This offers access to a myriad of possibilities for tuning the properties of enzymes. At this moment, however, the effects of post-production modification cannot yet be reliably predicted. The increasing number of applications will improve this so that the potential of this technology can be fully exploited. This review will focus on post-production modification of enzymes and its use and opportunities in industry.

  17. AGR-1 Post Irradiation Examination Final Report

    Energy Technology Data Exchange (ETDEWEB)

    Demkowicz, Paul Andrew [Idaho National Lab. (INL), Idaho Falls, ID (United States)

    2015-08-01

    The post-irradiation examination (PIE) of the Advanced Gas Reactor (AGR)-1 experiment was a multi-year, collaborative effort between Idaho National Laboratory (INL) and Oak Ridge National Laboratory (ORNL) to study the performance of UCO (uranium carbide, uranium oxide) tristructural isotropic (TRISO) coated particle fuel fabricated in the U.S. and irradiated at the Advanced Test Reactor at INL to a peak burnup of 19.6% fissions per initial metal atom. This work involved a broad array of experiments and analyses to evaluate the level of fission product retention by the fuel particles and compacts (both during irradiation and during post-irradiation heating tests to simulate reactor accident conditions), investigate the kernel and coating layer morphology evolution and the causes of coating failure, and explore the migration of fission products through the coating layers. The results have generally confirmed the excellent performance of the AGR-1 fuel, first indicated during the irradiation by the observation of zero TRISO coated particle failures out of 298,000 particles in the experiment. Overall release of fission products was determined by PIE to have been relatively low during the irradiation. A significant finding was the extremely low levels of cesium released through intact coatings. This was true both during the irradiation and during post-irradiation heating tests to temperatures as high as 1800°C. Post-irradiation safety test fuel performance was generally excellent. Silver release from the particles and compacts during irradiation was often very high. Extensive microanalysis of fuel particles was performed after irradiation and after high-temperature safety testing. The results of particle microanalysis indicate that the UCO fuel is effective at controlling the oxygen partial pressure within the particle and limiting kernel migration. Post-irradiation examination has provided the final body of data that speaks to the quality of the AGR-1 fuel, building

  18. Emergency contraception (post-coital Contraception).

    Science.gov (United States)

    Pham, Angie

    2002-06-01

    Emergency Contraception is a post-coital contraceptive for women who have had unprotected intercourse or have reason to believe that their contraceptive method has failed. The article focuses mainly on Emergency Contraceptive Pills (ECPs) because they are the most frequently used form of post-coital contraception. In 1997 the FDA approved the "off-label" use of high dose of oral contraceptives for use as post-coital contraception. Since then, they have been approved for repackaging and marketed solely for use as post-coital emergency contraception. The first dose of ECPs must be administered within 72 hours of the act of unprotected intercourse. The second dose is taken 12 hours later. ECPs are believed to work in one of three ways depending on where the woman is in her menstrual cycle when she seeks treatment. It can delay or prevent ovulation, impair formation of the corpus luteum, or cause histological or biochemical changes within the endometrium, thus preventing implantation. Their effectiveness is approximately 75%, being most effective when administered as quickly as possible after the act of unprotected intercourse. The pills can cause nausea and vomiting, so the pre-administration of an anti-emetic may help alleviate these symptoms. A major issue concerning the ECPs is the lack of knowledge and availability. Very few health-care providers discuss ECPs with their patients. Most people cited the media as the primary source of information. The 72-hour window in which the ECPs must be administered makes it important for women to have easy access to these post-coital contraceptives. However, women who seek treatment will often find that their health-care provider will require a physical exam and/or a pregnancy test before writing a prescription. Yet, studies show that ECPs do not affect an implanted fetus, and there are no emergency contraceptive protocols that require pregnancy tests or physical exams prior to treatment. The AMA is encouraging physicians to

  19. [Clinical forms of post-traumatic depression].

    Auxéméry, Y

    2015-09-01

    As a result of determinants specific to the psychopathological structure of the psychological trauma, psycho-traumatised patients very rarely solicit the health care system directly with a request for treatment centred on their trauma. The medical profession is consulted for non-specific symptoms and complications, which are mainly somatoform, addictions and depressive disorders. After a few epidemiological reminders followed by a discussion concerning contemporary depressive and post-traumatic nosographic features, we define, through our clinical experience collated with the data in the literature, different clinical and etiopathogenic contexts of post-traumatic depression in order to control their therapeutic treatment. Burnout post-traumatic depression in response to re-experiencing is the most common: it is a reactive psycho-physiological burnout in response to the emotional distress re-experienced during flashbacks, insomnia, a constant feeling of insecurity and the deleterious consequences of this symptomatology in terms of social adaptation. A common genetic predisposition affecting serotoninergic regulation seems to be a vulnerability marker of both depressive and psychotraumatic symptoms. In this case, SSRI will be effective on sadness. In addition, these antidepressants have been widely prescribed for the first-line treatment of depressive and psychotraumatic symptoms. However, this pharmacological class is often insufficient in relieving autonomic hyperactivity such as re-experiencing which are mediated more by noradrenergic hyperactivity. SNRI such as venlafaxine can be used as a first-line treatment. Post-traumatic depression with psychotic features congruent with mood is dominated by a feeling of incurability; the subject blames himself and feels guilty about the traumatic event and its consequences. Symptoms of denial of identity are sometimes observed: confined by an intense depersonalization, the psycho-traumatised subject evokes that he is "no

    The role of several imaging techniques in patients submitted to pancreatic surgery with special emphasis to single-slice helical computed tomography (CT) and multidetector-row CT (MDCT) was reviewed. Several surgical options may be performed such as Whipple procedure, distal pancreatectomy, central pancreatectomy, and total pancreatectomy. Ultrasound examination may be used to detect peritoneal fluid in the early post-operative period as well as lesion recurrence in long-term follow-up. Radiological gastrointestinal studies has a major role in evaluation of intestinal functionality. In spite of the advent of other imaging modalities, CT is the most effective after pancreatic surgery. On post-operative CT, the most common findings were small fluid peritoneal or pancreatic collections, stranding of the mesenteric fat with perivascular cuffing, reactive adenopathy and pneumobilia. In addition, CT may demonstrate early (leakage of anastomosis, pancreatico-jejunal fistula, haemorrage, acute pancreatitis of the remnant pancreas, peritonitis), and late (chronic fistula, abscess, aneurysms, anastomotic bilio-digestive stenosis, perianastomotic ulcers, biloma, and intra-abdominal bleeding) surgical complications. In the follow-up evaluation, CT may show tumor recurrence, liver and lymph nodes metastasis. Magnetic resonance may be used as alternative imaging modality to CT, when renal insufficiency or contrast sensitivity prevents the use of iodinated i.v. contrast material or when the biliary tree study is primarily requested. The knowledge of the type of surgical procedures, the proper identification of the anastomoses as well as the normal post-operative imaging appearances are essential for an accurate detection of the complications and recurrent disease.

    Full Text Available Por estos días se inaugura el “Centro de consulta post-mortem del Hospital Universitario del Valle”, una denominación más apropiada para la autopsia «ver por sí mismo» o cualquiera de sus sinónimos necropsia, examen post-mortem, necroscopia, o tanatopsia; todos ellos no aceptados y condicionados por factores culturales, sociales o religiosos. Estos términos han alcanzado una connotación claramente negativa en el ambiente médico y en el público general. Quizás, el mejor término sea «consulta post-mortem», porque representa en verdad un examen médico después de la vida, cuyos objetivos son la búsqueda de las causas de la muerte, el análisis de la enfermedad básica, sus efectos y complicaciones y las consecuencias de la intervención médica. Nadie puede dudar de los aportes a la medicina de la consulta post-mortem. Su carácter riguroso transformó la medicina animista en el presente científico. Así aprendimos las lesiones producidas en los órganos, las anomalías asociadas con los defectos congénitos, las infecciones silenciosas o la cardiopatía en el hipotiroidismo; nos ha permitido identificar nuevas enfermedades, nuevas formas o patrones de presentación de viejas enfermedades, reconocer a ciertos agentes patógenos, conocer cómo la terapéutica cambia la historia natural de ciertas enfermedades, etc., y, en consecuencia, cómo debemos replantear los enfoques terapéuticos y de manejo; y ha dado origen a ideas para tratamientos médicos y quirúrgicos y el control de la efectividad de los tratamientos médicos. Aunque hoy casi ninguna zona de nuestro organismo es inaccesible o escapa a la exploración con los avances de la tecnología y nos permite realizar diagnósticos más precisos.

    2013-07-01

    We examined methodological issues in studies of disaster-related effects on reproductive health outcomes and fertility among women of reproductive age and infants in the United States (US). We conducted a systematic literature review of 1,635 articles and reports published in peer-reviewed journals or by the government from January 1981 through December 2010. We classified the studies using three exposure types: (1) physical exposure to toxicants; (2) psychological trauma; and (3) general exposure to disaster. Fifteen articles met our inclusion criteria concerning research focus and design. Overall studies pertained to eight different disasters, with most (n = 6) focused on the World Trade Center attack. Only one study examined pregnancy loss, i.e., occurrence of spontaneous abortions post-disaster. Most studies focused on associations between disaster and adverse birth outcomes, but two studies pertained only to post-disaster fertility while another two examined it in addition to adverse birth outcomes. In most studies disaster-affected populations were assumed to have experienced psychological trauma, but exposure to trauma was measured in only four studies. Furthermore, effects of both physical exposure to toxicants and psychological trauma on disaster-affected populations were examined in only one study. Effects on birth outcomes were not consistently demonstrated, and study methodologies varied widely. Even so, these studies suggest an association between disasters and reproductive health and highlight the need for further studies to clarify associations. We postulate that post-disaster surveillance among pregnant women could improve our understanding of effects of disaster on the reproductive health of US pregnant women.

  12. Iron incorporation and post-malaria anaemia.

    Directory of Open Access Journals (Sweden)

    Conor P Doherty

    Full Text Available BACKGROUND: Iron supplementation is employed to treat post-malarial anaemia in environments where iron deficiency is common. Malaria induces an intense inflammatory reaction that stalls reticulo-endothelial macrophagal iron recycling from haemolysed red blood cells and inhibits oral iron absorption, but the magnitude and duration of these effects are unclear. METHODOLOGY/PRINCIPAL FINDINGS: We examined the red blood cell incorporation of oral administered stable isotopes of iron and compared incorporation between age matched 18 to 36 months old children with either anaemia post-malaria (n = 37 or presumed iron deficiency anaemia alone (n = 36. All children were supplemented for 30 days with 2 mg/kg elemental iron as liquid iron sulphate and administered (57Fe and (58Fe on days 1 and 15 of supplementation respectively. (57Fe and(58Fe incorporation were significantly reduced (8% vs. 28%: p<0.001 and 14% vs. 26%: p = 0.045 in the malaria vs. non-malaria groups. There was a significantly greater haemoglobin response in the malaria group at both day 15 (p = 0.001 and 30 (p<0.000 with a regression analysis estimated greater change in haemoglobin of 7.2 g/l (s.e. 2.0 and 10.1 g/l (s.e. 2.5 respectively. CONCLUSION/SIGNIFICANCE: Post-malaria anaemia is associated with a better haemoglobin recovery despite a significant depressant effect on oral iron incorporation which may indicate that early erythropoetic iron need is met by iron recycling rather than oral iron. Supplemental iron administration is of questionable utility within 2 weeks of clinical malaria in children with mild or moderate anaemia.

  13. Taylorism in a post-modern age?

    Science.gov (United States)

    Freemantle, N

    1995-02-01

    F.W. Taylor made an early and important contribution to the organisation of work in an industrial society. His ideas, or versions of his ideas, are once again receiving attention. Some commentators even describe a new or neo Taylorism (Pollitt, 1990). This paper argues that the only theoretical justification for the re-introduction of Taylorist strategies in the workplace is found in the notion of the post-modern world; where rationality is replaced by a ritual of signs and work becomes part of that ritual; where form replaces rationale, and strategies for work are governed by processes of survival in the remnants of modernity.

  16. Intelligent post processing of seismic events

    Directory of Open Access Journals (Sweden)

    F. Ringdal

    1994-06-01

    Full Text Available The Intelligent Monitoring Systern (IMS currently provides for joint processing of data from six arrays located in Northern and Central Europe. From experience with analyst review of events automatically defined by the IMS, we bave realized that the quality of the automatic event locations can be significantly improved if the event intervals are reprocessed with signal processing pararneters tuned to phases from events in the given region. The tuned processing parameters are obtained from off line analysis of events located in the region of interest. The primary goal of such intelligent post processing is to provide event definitions of a quality that minimizes the need for subsequent manual analysis. The first step in this post processing is to subdivide the arca to be monitored in order to identify sites of interest. Clearly, calibration will be the easiest and potential savings in manpower are the largest for areas of high, recurring seismicity. We bave identified 8 mining sites in Fennoscandia/NW Russia and noted that 65.6% of the events of ML > 2.0 in this region can be associated with one of these sites. This result is based on 1 year and a half of data. The second step is to refine the phase arrival and azimuth estimates using frequency filters and processing parameters that are tuned to the initial event location provided by the IMS. In this study, we have analyzed a set of 52 mining explosions from the Khibiny Massif mining area in the Kola peninsula of Russia. Very accurate locations of these events bave been provided by the seismologists from the Kola Regional Seismology Centre. Using an autoregressive likelihood technique we have been able to estimate onset times to an accuracy (standard deviation of about 0.05 s for P phases and 0.15 0.20 s for S phases. Using fixed frequency bands, azimuth can be estimated to an accuracy (one standard deviation of 0.9 degrees for the ARCESS array and 3 4 degrees for the small array recently

    Cogoni, C; Macino, G

    2000-12-01

    Post-transcriptional gene silencing (PTGS) as a consequence of the introduction of either transgenes or double-stranded RNA molecules has been found to occur in a number of species. In the past year, studies in different systems have greatly enhanced our understanding of the molecular mechanisms of these phenomena. The ubiquitous presence of PTGS in both the plant and animal kingdoms and the finding of common genetic mechanisms suggest that PTGS is a universal gene-regulation system fundamental in biological processes such as protection against viruses and transposons.

    Only a few studies have been reported on the MR contrast enhancement and the apparent diffusion coefficient (ADC) findings of the post-traumatic lesion of the brain. We report a case of the venous ischemia in the left frontal lobe observed in the MRI obtained one day after the incidence of trauma. Considering the presented slight increase in the ADC, the vasogenic edema was thought to be the major mechanism of the venous ischemia and excitotoxic injury. In spite of a slight increase in the ADC, the hyperintensity in the diffusion weighted imaging and contrast-enhanced areas eventually changed into hemorrhagic lesions.

    Smith, Joshua P; Arnoletti, J Pablo; Varadarajulu, Shyam; Morgan, Desiree E

    2008-01-01

    Acute pancreatitis can result in retroperitoneal fat necrosis, typically occurring in the peripancreatic region, with extension into the transverse mesocolon, omentum and mesenteric root. When evaluated with contrast enhanced computed tomography (CECT), acute peripancreatic post necrotic collections typically become lower in attenuation over time, and often appear as homogeneous fluid collections. Saponification as a complication of fat necrosis in patients with acute pancreatitis is a well recognized clinical entity. While retroperitonal fat necrosis is commonly seen on CECT, saponification is not a prominent imaging feature. We present a case of acute pancreatitis complicated by extensive saponification of fat throughout the retroperitoneum and peritoneal lining, mimicking carcinomatosis.

    This current world population has significantly added to the pressures placed upon our finite resources and our resulting ability to feed ourselves. In order to cope with current and future demands, the two established lines of action, that is, reduced population growth and expansion of agricultural production, must be supplemented with the parallel activity of reducing food losses during and after harvest. For developing countries in particular, enormous post-harvest losses result from spillage, contamination, pests and physiological deterioration during storage. Studies in these countries indicate that post-harvest losses are enormous and amount to tens of millions of tons per year valued at billions of dollars. Programs to reduce post-harvest losses, if applied properly, can result in realistic yield increases between 10 and 30%, which can be directly converted into increased consumption for humans. Post-harvest losses vary greatly and are a function of the crop variety, pest combinations in the environment, climate, the system of harvesting, storage, handling, marketing, and even the social and cultural environment. Pests are among the most criticals of these factors. Because of the disastrous potential consequences of such pests, quarantine regulations prohibit the entrance of plants or products which might hide the unwanted pest from countries where it is known to exist. Quarantine treatments are can be chemical, physical or ionizing radiation treatment. Numerous investigations on the use of ionizing radiation for the disinfestation of fresh plant materials indicate that rather low dosages will control fruit-fly problems, thus making it well suited for quarantine treatment. The effectiveness of the irradiation as a broad spectrum quarantine treatment of fresh fruits and vegetables was recognized by the several plant protection organizations around the world. Currently, some 40 countries have approved one or more irradiated food items or groups of food

    The number of patients surviving critical illness in the United States has increased with advancements in medicine. Post-intensive care syndrome and post-intensive care syndrome-family are terms developed by the Society of Critical Care Medicine in order to address the cognitive, psychological, and physical sequelae emerging in patients and their families after discharge from the intensive care unit. In the United Kingdom and Europe, intensive care unit follow-up clinics have been used to address the complications of post-intensive care syndrome for some time. However, the interprofessional clinic at Vanderbilt University Medical Center is among the first in the United States to address the wide variety of problems experienced by intensive care survivors and to provide patients and their families with care after discharge from the intensive care unit.

    2013-11-01

    We present a case where multi-phase post-mortem computed tomography angiography (PMCTA) induced a hemorrhagic pericardial effusion during the venous phase of angiography. Post-mortem non-contrast CT (PMCT) suggested the presence of a ruptured aortic dissection. This diagnosis was confirmed by PMCTA after pressure controlled arterial injection of contrast. During the second phase of multi-phase PMCTA the presence of contrast leakage from the inferior cava vein into the pericardial sac was noted. Autopsy confirmed the post-mortem nature of this vascular tear. This case teaches us an important lesson: it underlines the necessity to critically analyze PMCT and PMCTA images in order to distinguish between artifacts, true pathologies and iatrogenic findings. In cases with ambiguous findings such as the case reported here, correlation of imaging findings with autopsy is elementary.

    This study investigated the influence of clinical experience in relation to the efficacy and effectiveness of removal of 2 different fiber posts. In total, 48 intact single-rooted teeth were treated endodontically and obturated. Then, 10-mm post spaces were prepared, and fiber posts were luted. Twenty-four #1 D.T. Light-Posts were used in group 1, and 24 #2 Hi-Rem Prosthetic Posts were used in group 2. A pullout test (n = 8 per group) was performed by using a universal testing machine to compare bond strength. Then, fiber post removal efficacy and efficiency were tested. Each group was divided into 2 subgroups (n = 8) according to operator experience. In group 1, fiber posts were removed with an ultrasonic handpiece by using a #3 Start-X tip. In group 2, a size 25/0.04 ProFile was used to remove the central soft polymer macrofiber, and a #2 Largo drill was used to remove the fiber post and luting cement remnants. Post removal times were recorded to evaluate efficacy. Weight change was determined, and post space walls were analyzed microscopically to evaluate effectiveness. Bond strength did not differ significantly (P = .7569) between post systems. Post hoc Tukey tests indicated that removal time was affected significantly by operator experience in group 1 (P < .001) but not in group 2. Weight change was affected significantly by experience level in both groups. No difference in post space wall characteristics was observed between subgroups. The Hi-Rem post was easier to remove than the D.T Light-Post. Copyright © 2013 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

  4. Post-polio syndrome: renaissance of poliomyelitis?

    Directory of Open Access Journals (Sweden)

    Claudio Andre Barbosa de Lira

    2009-03-01

    Full Text Available Poliomyelitis is an acute and infectious viral disease, transmitted primarily through oral-fecal contact or directly, person to person. Approximately 90% of the individuals infected by the polio virus do not present symptoms; however, the affected individuals can show a variety of symptoms if the virus reaches the bloodstream. In up to 2% of cases, the virus reaches the central nervous system  preferably infecting and destroying the motor neurons, resulting in muscular weakness and acute flaccid paralysis. Despite the expressive reduction in the number of cases, many people live with the consequences of the acute illness, thus representing a burden to the public healthcare systems. Many of these people present new manifestations as signs and symptoms that are called post-polio syndrome. It can be defined and characterized by new neuromuscular symptoms, which occur at least 15 years after a period of clinical and functional stability in patients with previous history of symptomatic poliomyelitis. The signs and symptoms characterizing the post-polio syndrome include new muscular weakness, muscular fatigue and atrophy, pain in joints and muscles, sleep disorders, intolerance to cold, respiratory and swallowing difficulties, and recent weight gain. Therefore, the aim of this review is to present the physiological changes caused by the new manifestation of symptoms in individuals with poliomyelitis.

    Full Text Available We introduce a method to obtain self-consistent, axially symmetric disklike stellar models in the first post-Newtonian (1PN approximation. By using in the field equations of the 1PN approximation a distribution function (DF corresponding to a Newtonian model, two fundamental equations determining the 1PN corrections are obtained. The rotation curves of the corrected models differs from the classical ones and the corrections are clearly appreciable with values of the mass and radius of a typical galaxy. On the other hand, the relativistic mass correction can be ignored for all models. Resumen.

  6. [The post-traumatic stress disorder].

    Many people experience a potentially traumatic event during their lives, which can result in brief periods of post-traumatic stress symptoms; this is a normal reaction. Most people can deal with a traumatic event when supported by significant others, but 10% of them develop post-traumatic stress disorder (PTSD). The nature of the traumatic event, the duration of exposure and the age at which one experiences such an event partly determine whether a person will develop PTSD. Psychological debriefing (a single-session consultation) does not prevent the development of PTSD; it is therefore not useful to offer this to everyone who has experienced a traumatic event. New and promising developments have, however, arisen in this regard. Trauma-focused psychotherapy has proved to be effective for patients with PTSD, possibly in combination with medication. Individuals who experience many or severe initial symptoms after a traumatic event may benefit from early, short-term, trauma-focused psychotherapy for preventing the development of chronic PTSD. Developments pertaining to the DSM-5 pay more attention to 'complex' PTSD, a type which is often the result of long-term traumatisation during childhood.

    Full Text Available With increasing consumer requirements, farmers and vendors see the importance of social media as a marketing tool to engage with consumers. In particular, on a more personal level for reasons of brand management. Instagram is becoming increasingly popular as a marketing communication tool. The aim of this paper is to identify areas that users evaluate in terms of positive feelings in connection with farmers’ markets. The results are based on the analysis of the worldwide, and Czech, instagram social network. Instagram posts were identified on the basis of keywords, such as #farmarsketrhy and #farmersmarkets. The results of the study are based on 100,000 contributions on Instagram made by 55,632 users. The analysis contains 1,357,812 ‘unique’ words. The results identified six major areas (1 Healthy (2 Good (3 Great (4 Happy (5 Nice (6 Perfect. An appropriately posted hashtag indicated the positive feelings that were evoked and then assigned to a matching category. The research results are used to identify group characteristics that exert these positive feelings while visiting farmers’ markets. These results can be used to build communications campaigns for farmers’ markets. They can also be used as a basis for further research in defining the behaviour of farmers’ markets visitors, based on cultural differences arising from geographic location.

    Post-intubation tracheal stenosis accounts for the greatest proportion of whole-cause tracheal stenosis. Treatment of post-intubation tracheal stenosis requires a multidisciplinary approach. Surgery or an endoscopic procedure can be used, depending on the type of stenosis. However, the efficacy of cryotherapy in post-intubation tracheal stenosis has not been validated. Here, we report a case of recurring post-intubation tracheal stenosis successfully treated with bronchoscopic cryotherapy that had previously been treated with surgery. In this case, cryotherapy was effective in treating web-like fibrous stenosis, without requiring more surgery. Cryotherapy can be considered as an alternative or primary treatment for post-intubation tracheal stenosis.

    Posterior-stabilized (PS) total knee arthroplasty (TKA) components employ a tibial post and femoral cam mechanism to guide anteroposterior knee motion in lieu of the posterior cruciate ligament. Some PS TKA patients report a clicking sensation when the post and cam engage, while severe wear and fracture of the post; we hypothesize that these complications are associated with excessive impact velocity at engagement. We evaluated the effect of implant design on engagement dynamics of the post-cam mechanism and resulting polyethylene stresses during dynamic activity. In vitro simulation of a knee bend activity was performed for four cadaveric specimens implanted with PS TKA components. Post-cam engagement velocity and flexion angle at initial contact were determined. The experimental data were used to validate computational predictions of PS mechanics using the same loading conditions. A lower limb model was subsequently utilized to compare engagement mechanics of eight TKA designs, relating differences between implants to geometric design features. Flexion angle and post-cam velocity at engagement demonstrated considerable ranges among designs (23°-89°, and 0.05-0.22 mm/°, respectively). Post-cam velocity was correlated (r = 0.89) with tibiofemoral condylar design features. Condylar geometry, in addition to post-cam geometry, played a significant role in minimizing engagement velocity and forces and stresses in the post. This analysis guides selection and design of PS implants that facilitate smooth post-cam engagement and reduce edge loading of the post.

    Survival of endodontically treated, post-restored teeth depends on a multitude of factors, all of which are practically impossible to include in a randomized, controlled clinical study. The purpose of this survey was to characterize and analyze reported failures of post-retained restorations...... to identify factors critical to failure and to type of failure. A questionnaire was mailed to private practitioners in Denmark with a request to complete the questionnaire whenever a patient presented with a failed post-retained restoration. Information was gathered on factors related to the patient...... increased with the functioning time until failure. Fracture of the post was more common among male than female patients. On the basis of this survey of failed post-retained restorations, it was concluded that tapered posts were associated with a higher risk of tooth fracture than were parallel-sided posts....

  12. Exploratory experimental investigations on post-tensioned structural glass beams

    Directory of Open Access Journals (Sweden)

    Christian Louter

    2015-05-01

    Full Text Available The mechanical response of post-tensioned glass beams is explored in this paper. This is done through bending experiments on post-tensioned glass beam specimens with either mechanically anchored or adhesively bonded steel tendons by which a beneficial pre-stress is inflicted on the glass beams. In addition, reference beams with identical geometry but without tendons are tested. From the results of the bending experiments it can be seen that the post-tensioned glass beams reach higher initial fracture loads than the reference glass beams. Furthermore, the post-tensioned glass beams develop a significant post-fracture reserve. From this it is concluded that post-tensioning a glass beam is a feasible concept, which provides increased initial fracture strength and enhanced post-fracture performance.

  13. Post-operative antibiotics after appendectomy and post-operative abscess development: a retrospective analysis.

    2013-02-01

    Appendectomy is one of the most common emergency operations. Prophylaxis against infective complications involves post-operative antibiotics. There is no consensus as to the optimum antibiotic regimen. This study aimed to assess the relation between the duration of the post-operative antibiotic administration and intra-abdominal infections (IAIs). All patients who underwent appendectomy between September 1, 2009, and August 31, 2010, were identified. The appearance of the appendix at operation, post-operative antibiotics, white blood cell count, and temperature at the time of conversion of intravenous (IV) to oral antibiotics were compiled. IAIs were assessed as the final outcome. Two hundred sixty six patients underwent appendectomy-188 for simple appendicitis and 78 for complicated appendicitis. There were 18 IAIs (6.8%) overall, 10 (12.8%) after complicated appendicitis and eight (4.2%) after simple appendicitis. Prolonging antibiotics beyond the operation in the simple appendicitis group did not alter the incidence of IAI. Similarly, in the complicated appendicitis group, prolonging antibiotics beyond five days did not alter the incidence of IAI. Furthermore, in patients with complicated appendicitis, the presence of leukocytosis, fever, or both when IV antibiotics were converted to oral drugs was associated with the development of IAI (p=0.013). In simple appendicitis, post-operative antibiotics may not be beneficial at all. In complicated appendicitis, prolonging the course of antibiotics was not associated with a reduced IAI rate. However, cessation of IV antibiotics when fever or leukocytosis was present was associated with IAI development.

  15. Contemporary Welfare Regimes in Baltic States: Adapting Post-Communist Conditions to Post-Modern Challenges

    Directory of Open Access Journals (Sweden)

    Anu Toots

    2010-11-01

    Full Text Available This article revises the conventional approach to welfare state development in the post-communist world, according to which the main challenge for the Eastern European states is to catch up with Western European welfare regimes. The article argues that adjustment to the new social risks and volatile markets is more important today than the catching-up scenario. Based on social and labour market statistics for Estonia, Latvia and Lithuania, the article analyses how the Baltic States are coping with this adjustment challenge. Adaptation to the post-modern conditions can be regarded as successful if the stability of welfare spending is accompanied by the expanding and flexible employment and by the stable or decreasing level of poverty. The findings suggest that the opportunities to increase the flexibility and equality of the labour market provided by the breakdown of the communist regime were not used. Instead, the Baltic welfare states continue to focus on protecting against the old social risks by combining neoliberal and post-communist principles. Poor performance in meeting new social risks poses a greater challenge for the post-communist welfare states than their lag in terms of gross welfare expenditure.

    Delirium is a common post-operative complication associated with significant costs, morbidity, and mortality. We sought sleep/EEG predictors of delirium present prior to delirium symptoms to facilitate developing and targeting therapies. Continuous EEG data were obtained in 12 patients post-orthopedic surgery from the day of surgery until delirium assessment on post-operative day 2 (POD2). Diminished total sleep time (r=-0.68; pdelirium severity. Patients experiencing delirium slept 2.4h less and took 2h longer to fall asleep. Greater waking EEG delta power (r=0.84; pdelirium severity. Loss of sleep on night1 post-surgery is an early predictor of subsequent delirium. EEG Delta Power alterations in waking and sleep appear to be later indicators of impending delirium. Further work is needed to evaluate reproducibility/generalizability and assess whether sleep loss contributes to causing delirium. This first study to prospectively collect continuous EEG data for an extended period prior to delirium onset identified EEG-derived indices that predict subsequent delirium that could aid in developing and targeting therapies.

    2011-04-01

    Violence and armed conflict situations besetting numerous developing countries inflict a heavy toll on populations, especially in terms of posttraumatic mental disorders. In addition to upsetting the well-being and psychic balance of people, violent political instability prevents development of the country as a whole not only economically but also individually and socially. After being confronted with this reality for years, humanitarian workers have implemented actions aimed at treating and helping traumatized people to recover their mental health as a first step to achieving effective and durable development. However, despite the availability of effective low-cost treatment for post-traumatic mental disorders, officials in developing countries as well as in international organizations continue to ignore or neglect this crucial issue. This article is based on a study carried out by "Crisis prevention and post-conflict unit" of the Agence Française de Développement. The purpose is to underline the need and describe available methods for management of post-traumatic stress disorders in populations of post-conflict countries, as prerequisite for sustainable reconstruction and development.

    One of the clinically relevant problems dentists face when restoring endodontically treated teeth is the mismatch between fiber post and post space diameters, which results in an excessively thick resin cement layer. Fiber post relining appears as a solution for this problem. The aim of this study was to evaluate the effect of fiber post relining with composite resin on push-out bond strength. Twenty bovine incisors were selected to assess post retention. The crowns were removed below the cementoenamel junction and the root canals were treated endodontically and flared with diamond burs. The roots were allocated into two groups (n=10): G1: fiber posts without relining and G2: fiber posts relined with composite resin. The posts were cemented with a dual-cured resin cement and the specimens were sectioned transversally. Three 1.5-mm thick slabs were obtained per root and identified as cervical, medium and apical thirds. The push-out test was performed at a crosshead speed of 0.5 mm/min until post dislodgement occurred. The failure mode of fractured specimens was analyzed under scanning electron microscopy. Data were analyzed by split-plot ANOVA and post-hoc Tukey's test at a pre-set alpha of 0.05. Relined fiber posts presented higher retention values than non-relined post in all thirds. No statistically significant differences (p>0.05) were found among thirds for relined posts. All failures occurred at the interface between resin cement and root dentin. Relining with composite resin seems to be an effective method to improve the retention of fiber posts to flared root canals.

    2008-06-01

    In many scientific studies, information that is not easily translated into covariates is ignored in the analysis. However, this type of information may significantly improve inference. In this research, we apply the idea of judgment post-stratification to utilize such information. Specifically, we consider experiments that are conducted under a completely randomized design. Sets of experimental units are formed, and the units in a set are ranked. Estimation is performed conditional on the sets and ranks. We propose a new estimator for a treatment contrast. We improve the new estimator by Rao-Blackwellization. Asymptotic distribution theory and corresponding inferential procedures for both estimators are developed. Simulation studies quantify the superiority of the new estimators and show their desirable properties for small and moderate sample sizes. The impact of the new techniques is illustrated with data from a clinical trial.

  6. Post-liquefaction reconsolidation of sand.

    Science.gov (United States)

    Adamidis, O; Madabhushi, G S P

    2016-02-01

    Loosely packed sand that is saturated with water can liquefy during an earthquake, potentially causing significant damage. Once the shaking is over, the excess pore water pressures that developed during the earthquake gradually dissipate, while the surface of the soil settles, in a process called post-liquefaction reconsolidation. When examining reconsolidation, the soil is typically divided in liquefied and solidified parts, which are modelled separately. The aim of this paper is to show that this fragmentation is not necessary. By assuming that the hydraulic conductivity and the one-dimensional stiffness of liquefied sand have real, positive values, the equation of consolidation can be numerically solved throughout a reconsolidating layer. Predictions made in this manner show good agreement with geotechnical centrifuge experiments. It is shown that the variation of one-dimensional stiffness with effective stress and void ratio is the most crucial parameter in accurately capturing reconsolidation.

    2012-09-01

    Full Text Available The traditional mainline and evangelical churches in Canada, as in most western countries, are either in decline or static. Taken as a measure of the future, the prospects for Christianity in Canada, and more broadly the West, are bleak. Post-Christian Canada, however, contains thriving alternative and innovative forms of church, often called ‘emerging’ churches. They take many forms of expression, but share common theological convictions. Based on site research and personal interviews, this article describes the various types and contexts of these churches in Canada. It then highlights three of their central theological characteristics. First, rejecting the ‘culture wars’ social involvement of Christendom churches, they embrace practices and initiatives that transform their local communities. Second, they embrace an incarnational and contextual understanding of Christian life and ministry. Eschewing mega-church franchise models, they endeavor to shape their ministry to the their local communities. Third, they adopt a comprehensive rather than compartmental spirituality.

    Under the long-term monitoring of patients treated in childhood or adolescence for cancer, we present in this article the long-term monitoring and therefore possible effects of patients who underwent allergenic hematopoietic stem cell transplantation. This article is based on a collaborative effort organized by the French Society of Bone Marrow Transplantation and Cell Therapy (SFGM-TC), which took place during the 4th day of allograft harmonization practices. Patients affected are children and young adults (0-25 years). We defined the monitoring effects beyond 1 year post-transplant. Our recommendations are based on a literature review, in line with the Leucémie Enfant Adulte (LEA) study cohort of long-term monitoring of patients treated for hematological malignancies in childhood, grafted or not. It became important to determine the nature of problems, their risk factors, frequency and monitoring necessary to implement for their detection. We will not address the therapeutic management of sequelae.

    Full Text Available In the form of the Transcendental Meditation program CAM offers a method of eliminating deep-rooted stress, the efficacy of which has been demonstrated in several related studies. Any discussion of CAM and post-traumatic stress disorder should include a study of its application to Vietnam War Veterans in which improvements were observed on all variables, and several participants were able to return to work after several years of being unable to hold a job. The intervention has been studied for its impact on brain and autonomic nervous system function. It has been found to be highly effective against other stress-related conditions such as hypertension, and to improve brain coherence—a measure of effective brain function. It should be considered a possible ‘new and improved mode of treatment’ for PTSD, and further studies of its application made.

    Full Text Available Swelling or oedema of forehead or eyelids is a common consequence of hair transplantation surgery. However, this results in increased morbidity and absence from work due to unaesthetic appearance. To study various physical and therapeutic modalities to reduce or completely prevent the occurrence of such oedema. Three hundred forty hair transplant patients were recruited in the study and were categorized into 8 groups depending upon the intervention employed. There were 32 dropouts in the study due to various reasons. Patients who were administered steroid with tumescent solution had the highest number of patients without oedema, with only 3 out of 117 patients developing oedema. Physical measures like position of head during sleeping, application of occlusion bands or ice packs did not show satisfactory results. Addition of triamcinolone to tumescent anaesthetic solution is a very effective technique of preventing post-operative swelling.

    Full Text Available Presentamos un método para obtener modelos estelares discoidales, axialmente simétricos, auto-consistentes en la primera aproximación post-Newtoniana (1PN. Usando en las ecuaciones de campo de la aproximación 1PN una función de distribución conocida (DF que corresponde a un modelo Newtoniano, se obtienen dos ecuaciones fundamentales para determinar las correcciones 1PN. Las curvas de rotación de los modelos corregidos difieren de las clásicas y las correcciones son claramente apreciables con los valores de la masa y el radio de una galaxia típica. Por otro lado, la corrección relativista de la masa se puede ignorar para todos los modelos.

    Properties of high absorbency and modulus (gel rength) were both needed in applications of superabsorbent polymer (SAP). Generally, the absorption characteristic and gel strength reach a crossover point for a given system. Beyond this point, a given property will show improvement at the expense of another property. To synthesize SAP with properties superior to this optimum value, further modification in the process becomes essential. In our post-treatment modification of superabsorbent polymer, neither the variety of the crosslinkers, nor their amount was found the effective factors to the polymer performance, but the liquor ratio of the treating liquid to polymer. The combination of the chemical treating and heat-treating method was also explored. But this didn't put any positive effect on SAP's properties.

    Full Text Available Combi laser therapy was evaluated in 50 cases of established post herpetic neuralgia (PHN. Established PHN term was used when neuralgia persisted after 3 months of disappearance of herpes zoster (HZ vesicles. Twenty exposures were given and affected areas were irradiated from a distance of 2 cm at a frequency of 5000 Hz each area being exposed for a period of 1.23 minutes ie, 8J/cm2 of beam was given. Therapeutic evaluation was done on 4th, 8th, 12th, 16th, and 20th day. All 17 cases of established PHN of duration upto 3 months healed after 16 exposures and in the end 44/50 had cure, 5/50 had partial relief and one patient left trial after 2nd exposure.

    Post-irradiation effects (PIE) ranging from normal recovery to catastrophic failure have been observed in integrated circuits during the PIE period. Data presented show failure due to rebound after a 10 krad(Si) dose. In particular, five device types are investigated with varying PIE response. Special attention has been given to the HI1-507A analog multiplexer because its PIE response is extreme. X-ray diffraction has been uniquely employed to measure physical stress in the HI1-507A metallization. An attempt has been made to show a relationship between stress relaxation and radiation effects. All data presented support the current MIL-STD Method 1019.4 but demonstrate the importance of performing PIE measurements, even when mission doses are as low as 10 krad(Si).

    2009-01-01

    Post-infectious irritable bowel syndrome (PI-IBS) is a common disorder wherein symptoms of IBS begin after an episode of acute gastroenteritis. Published studies have reported incidence of PI-IBS to range between 5% and 32%. The mechanisms underlying the development of PI-IBS are not fully understood, but are believed to include persistent sub-clinical inflammation, changes in intestinal permeability and alteration of gut flora. Individual studies have suggested that risk factors for PI-IBS include patients' demographics, psychological disorders and the severity of enteric illness. However, PI-IBS remains a diagnosis of exclusion with no specific disease markers and, to date, no definitive therapy exists. The prognosis of PIIBS appears favorable with spontaneous and gradual resolution of symptoms in most patients.

    2005-11-01

    Post-herpetic neuralgia (PHN) is the most frequent complication of herpes zoster and often results in significant morbidity and a reduction in the patient's quality of life. The peripheral nerve injury that occurs during the acute phase of herpes zoster (HZ) leads to an abnormal tonic impulse discharge from primary nociceptive afferent neurons which induce slow temporal summation. This "wind-up" phenomenon is responsible for continuous partial depolarisation of second-order neurons with increased spontaneous impulse discharge and expanded receptive fields within the dorsal horn nociceptive neurons. The abnormal central processing involves the activation of N-methyl-D-aspartate (NMDA) receptors resulting in neuropathic pain, characterized by spontaneous pain, hyperalgesia and allodynia which is typical of PHN. In addition, tonic input from non-nociceptive AB afferent neurons, maintained by sympathetic efferent activity, contribute to the development and maintenance of neuropathic pain in general, and a burning sensation in particular.

    1992-09-01

    A method of using light-cured acrylic resin as an alternative to the use of chemically-cured acrylic resins with elastomeric impressions for direct post patterns is presented. The GC Unifast LC acrylic resin is a powder/liquid type resin cured by exposure to visible light. The polymerization process has four stages before final curing: slurry, stringy, dough-like (plastic), and rubber-like (elastic). Advantages over current direct and indirect procedures include ease of manipulation of the material and no change in laboratory handling procedures. While in the dough-like state, the material can be contoured. In the rubber-like state, it is flexible to disengage from minor undercut areas.

    Full Text Available This paper is about an instrumental research conducted in order to compare the information given by two multivariate data analysis used fordividing a population in clusters. These methods are K-means cluster and TwoStep cluster, which are available in SPSS system. Such methods could be used in post-hoc market segmentations, which allow companies to find segments with specific behaviours or attitudes. The research scope is to find which of the two methods is better for market segmentation practice. The outcomes reveal that every method has strong points and weaknesses. These ones are related to the relevance of segments description and the statistic significance of the difference between segments. In this respect, the researchers should compare the results of the named analyses and choose the method which better discriminate between the market segments.

    Post-polio syndrome (PPS) is the commonly affected term to describe the symptoms that may develop many years after acute paralytic poliomyelitis. The etiology of PPS is still unclear. An overuse of enlarged motor units is suspected causing denervation again due to distal degeneration of axons. Metabolic and functional changes has been described in muscle fibers of partially denervated muscles. Nevertheless, submaximal aerobic training and low intensity muscular strengthening have shown positive effects on muscular strength and cardiorespiratory system in patients affected by PPS. Aquatic therapy has a positive impact on pain and muscle function. In patients with severe fatigue, it is recommended to adapt the daily exercise routine to their specific case.

    Most patients who remain comatose for a few hours after a period of global cerebral ischemia have a poor prognosis. Early identification of these patients is desirable to reduce uncertainty about treatment and non-treatment decisions, and to improve relationships with the family. The absence of pupillary light response and corneal reflexes, absent or stereotyped extension motor response to noxious stimulation (3 days after insult); myoclonus status epilepticus; absence of cortical N20 response on somatosensory evoked potential studies; generalised suppression or burst-suppression EEG and serum neuron-specific enolase above 33 microg/L (sampled 1-3 days after insult) have been shown to predict poor outcome. We here propose an algorithm to help intensive care physicians' clinical decision making in post-anoxic coma.

    2008-01-01

    The seven-year run-up to the Olympics has seen China’s white-hot economy chug along with an annual growth rate of more than 10 percent. But the global economic race is more of a marathon than a sprint. Several former Olympic host countries, including Japan and Australia, suffered economic slumps to varying degrees after the euphoria. Now eyes are turning to China to see if the Games will have a similar impact after they end. Will a post-Olympic slowdown play out here, or could it even prompt another economic take-off in the country? China Development Observation, a business monthly, interviewed Chen Jian, Executive Director of the Beijing Olympic Economy Research Association; Li Yining, a renowned economist; and Zhuang Jian, a senior economist at the Asian Development Bank China Resident Mission, for some answers.

    Bell inequality violations can be used to certify private randomness for use in cryptographic applications. In photonic Bell experiments, a large amount of the data that is generated comes from no-detection events and presumably contains little randomness. This raises the question as to whether randomness can be extracted only from the smaller post-selected subset corresponding to proper detection events, instead of from the entire set of data. This could in principle be feasible without opening an analogue of the detection loophole as long as the min-entropy of the post-selected data is evaluated by taking all the information into account, including no-detection events. The possibility of extracting randomness from a short string has a practical advantage, because it reduces the computational time of the extraction. Here, we investigate the above idea in a simple scenario, where the devices and the adversary behave according to i.i.d. strategies. We show that indeed almost all the randomness is present in the pair of outcomes for which at least one detection happened. We further show that in some cases applying a pre-processing on the data can capture features that an analysis based on global frequencies only misses, thus resulting in the certification of more randomness. We then briefly consider non-i.i.d strategies and provide an explicit example of such a strategy that is more powerful than any i.i.d. one even in the asymptotic limit of infinitely many measurement rounds, something that was not reported before in the context of Bell inequalities.

  12. Training in post-authorization pharmacovigilance

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Post-authorization pharmacovigilance refers to all the activities relating to the detection, assessment, understanding and prevention of adverse effects or any other drug-related problems, from the time a product gets the authorization to be marketed in a territory. The ultimate objective of pharmacovigilance is patient safety. To ensure this, any responsible pharmaceutical company will readily vouch for the importance of all these activities, each requiring specific training for efficient and effective execution. Having a well planned job specific training curriculum can help the organization realize its goals and objectives by covering the gaps between current and desired job performance levels and existing competencies of its employees. Apart from this, trainings can help in problem solving, increasing productivity and prepare for and respond to future changes in the organization or job duties. As the pharmaceutical business continues to grow, increasing numbers of skilled people are required to manage resultant increase in pharmacovigilance activities to remain compliant. Thus, the need for training qualified resources to develop into highly skilled pharmacovigilance professionals is the need of the hour. Currently, the supply-demand situation for skilled manpower is highly skewed in favor of the demand, as this field is relatively new in India and elsewhere. It is interesting to note that not many resources, be it internet, literature or books, are available specifically addressing the need of the industry to guide them on training requirements to set up and maintain a competent pharmacovigilance department. This article aims to present a comprehensive perspective on the trainings required in the post authorization scenario pertaining to pharmacovigilance activities and suggest ways to manage these in an efficient way so as to be compliant with the global norms and best practices.

    Recently, with improvements in surgical techniques there has been a substantial reduction in the incidence of biliary complications of hepatobiliary surgery. Nevertheless, bile duct injuries and other post-cholecystectomy complications are a serious problem and a major cause of morbidity and mortality. Early complications may include bile duct injury caused by mistakenly placed clips, erroneous cutting of bile ducts based on misinterpretation of biliary anatomy, periductal bile leakage that causes edema, fibrosis and secondary stricturing, and ischemia due to injury to the right hepatic artery. Bile duct strictures are the most common of the late complications and can develop a few months or many years after surgery. Early detection and accurate diagnosis have a fundamental importance for the successful treatment of these complications. Therefore, early and meaningful application of the imaging methods immediately after detection of the first symptoms is essential. Peroperative ultrasound and direct iodine contrast application into the biliary tree (operative cholangiography) are highly important for immediate visualization of the complications during surgery. Ultrasound can be used to aid in identification of ductal structures and the cholangiogram should be obtained to document the anatomy. Plain abdominal film could be made in the patients in poor clinical conditions after biliary surgery. Oral cholecystography has largely been replaced by ultrasonography (US) for evaluation of cholelithiasis and complications like post-cholecystectomy fluid collections. The same methodology replaced the conventional intravenous cholangiography. Nowadays computed tomography (CT), endoscopic retrograde cholangiopancreatography (ERCP), magnetic resonance cholangiography (MRCP) and ultrasound (US) have essential roles as primary imaging modalities after biliary tree and gallbladder surgery in the evaluation of associated complications and residual biliary stones. We review the role

  14. POST Earthquake Debris Management - AN Overview

    Science.gov (United States)

    Sarkar, Raju

    Every year natural disasters, such as fires, floods, earthquakes, hurricanes, landslides, tsunami, and tornadoes, challenge various communities of the world. Earthquakes strike with varying degrees of severity and pose both short- and long-term challenges to public service providers. Earthquakes generate shock waves and displace the ground along fault lines. These seismic forces can bring down buildings and bridges in a localized area and damage buildings and other structures in a far wider area. Secondary damage from fires, explosions, and localized flooding from broken water pipes can increase the amount of debris. Earthquake debris includes building materials, personal property, and sediment from landslides. The management of this debris, as well as the waste generated during the reconstruction works, can place significant challenges on the national and local capacities. Debris removal is a major component of every post earthquake recovery operation. Much of the debris generated from earthquake is not hazardous. Soil, building material, and green waste, such as trees and shrubs, make up most of the volume of earthquake debris. These wastes not only create significant health problems and a very unpleasant living environment if not disposed of safely and appropriately, but also can subsequently impose economical burdens on the reconstruction phase. In practice, most of the debris may be either disposed of at landfill sites, reused as materials for construction or recycled into useful commodities Therefore, the debris clearance operation should focus on the geotechnical engineering approach as an important post earthquake issue to control the quality of the incoming flow of potential soil materials. In this paper, the importance of an emergency management perspective in this geotechnical approach that takes into account the different criteria related to the operation execution is proposed by highlighting the key issues concerning the handling of the construction

    Purton, D G; Love, R M; Chandler, N P

    2000-01-01

    Ceramic root-canal posts offer potential advantages over other types with respect to aesthetics and biocompatibility. Any post must be sufficiently rigid and retentive to withstand functional forces. Ceraposts (1.2 mm coronal diameter, ceramic, tapering, smooth posts) and Paraposts (1.25 mm, stainless-steel, parallel, serrated posts) were tested for rigidity by means of a three-point bending test. To test retention in roots, ceramic posts were cemented using one of three protocols: (1) glass-ionomer cement, (2) silane coupling agent and resin cement, or (3) sandblasted post surface, silane coupling agent, and resin cement. Stainless-steel posts were cemented with resin. The tensile force required to dislodge the posts, following four weeks of storage in water, was recorded. Data were compared using Student's t-test and Mann-Whitney U analysis. Ceraposts were significantly more rigid than Paraposts (p < 0.001). Paraposts cemented with resin were significantly more strongly retained than Ceraposts following any cementation protocol (p < 0.001). Retention of the ceramic posts was significantly greater with a silane coupling agent and resin cement than with glass-ionomer cement (p < 0.001). Sandblasting the ceramic posts produced variable results and needs further investigation before it could be recommended.

    The primary objective was to characterize the underlying intent of Instagram posts using the hashtag metadata term "#pharmacist" over a 1-year period. The secondary objective was to determine whether statistically significant relationships existed between the categories and the 2 dichotomous variables tested, self-portrayed images, and relation to health care. Retrospective, cross-sectional, mixed methods, exploratory, descriptive study. A review of available Instagram posts using the hashtag metadata "#pharmacist" from November 4, 2014, to November 3, 2015. Data were collected using software provided by NEXT Analytics. A sample of 14 random days was selected. Six hundred sixty-one Instagram posts containing "#pharmacist" in the caption. Categorization of post (including both picture and primary caption), self-portrayed images (i.e., "selfie"), and health care-related images. One thousand three hundred thirty-eight posts were collected from the 14-day sample. Of the posts, 661 (49.4%) were analyzed; the remainder were excluded for being written in a non-English language or containing "#pharmacist" in the comments of the post, rather than the primary caption; 19.7% of all posts fell into the Celebration category, followed by Work Experience and Advertisement with 18.6% and 12.6%, respectively. The remainder of the categories contained 10% or fewer posts. Less than 25% of posts were self-portrayed images, and 88% of posts were deemed health care-related. Instagram is an emerging social media platform that can be used to expand patient education, professional advocacy, and public health outreach. In this study, the majority of #pharmacist posts were celebratory in nature, and the majority were determined to be related to health care. Posts containing #pharmacist may provide the opportunity to educate the public regarding the knowledge and capabilities of pharmacists. Copyright © 2017 American Pharmacists Association®.

    Full Text Available Background: Post-retained crowns are indicated for endodontically treated teeth (ETT with severely damaged coronal tissue. There are still controversies for the most suitable choice of restorative material and the placement method that will result in the highest success rate. This clinical study compares the metal post and fiber post ins the restoration of the endodontically treated teeth. Materials and Methods: Forty endodontically treated and indicated for the post and core were selected for the study and divided into 2 groups equally. In, one group patient′s teeth were restored by metal post, while other group patient′s teeth were treated by fiber post. Comparative evaluation was done on follow-up of the patients on the basis of selected clinical and radiographical criteria. The results were compared using student′s t test with the help of IBM SPSS Statistics 20. Results: More number of failures was noted in patients whose teeth restored with the metal post as compared to those of the fiber post, both clinically as well as radiographically. (Student′s t test, P < 0.01. Conclusion: From the present study, it was shown that fiber post retained restored teeth has less chances of failure as compared to that of metal post. But the results of the present study should be supported by carrying out study on large scale.

    We report results of extensive experimental and numerical studies of the anisotropy of water drops deposited on single rectangular posts of mesoscopic size sculpted on different materials. Drops of different volume deposited on the top face of the posts assume an elongated shape along the post direction. Systematic investigations show that while the angle measured along the direction parallel to the post does not change, the one measured across them increases monotonically with the drop volume. The difference in these two angles is found to be proportional to the contact line eccentricity even for very elongated drops, regardless of the post size and material. Results obtained with the lattice Boltzmann method are consistent with these observations and indicate useful trends on the evolution of the drop shape with the system main parameters. We argue that drops deposited on single posts having a very sharp profile represent an ideal model system to investigate anisotropic wetting.

    Post-stroke depression is an important psychological consequence of ischemic stroke, and affects around one third of stroke patients at any time post-stroke. It has a negative impact on patient morbidity and mortality, and as such development of effective post-stroke recognition and treatment strategies are very important. There are several therapeutic strategies for post-stroke depression, including both pharmacological and non-pharmacological approaches. In this review, we present evidence regarding the underlying biology of post-stroke depression, commonalities between post-stroke depression and Major Depressive Disorder and explore several treatment approaches, including antidepressant therapy, psychotherapy, surgical therapy, electroconvulsive therapy, acupuncture, music therapy and natural products. Further experimental and clinical studies are required, particularly in emerging fields such as the role of nutraceuticals in the treatment of stroke.

    This research examined the effects of providing a monitoring and self-sanctioning system, called "hostage posting" in economics, on the improvement of trustworthiness. We conducted two questionnaire-type experiments to compare the trust-improving effects among the three conditions, (a) a voluntary provision of a monitoring and self-sanction system by the manager, (b) an imposed provision, and (c) an achievement of satisfactory management without any types of provisions. Total of 561 undergraduate students participated in the experiments. Results revealed that perceived integrity and competence were improved to almost the same level in both conditions (a) and (c), whereas these were not improved in condition (b). Consistent with our previous research, these results showed that the voluntary hostage posting improved trustworthiness level as well as a good performance did. The estimation of necessity of the system, however, was not different across these conditions. The implications for management practice and directions for future research were discussed.

    Full Text Available Over the past decade, the impact of the terroristic attacks of September 11, 2001 on American culture has been the prominent subject of various discussions. This has led to a large body of theoretical and experimental works known as ‘post-9/11’, which provides evidence for what Smelser’s believes to be the cultural trauma of 9/11. This study sets out to present a review of post 9/11 literature, with the perspective of cultural trauma as suggested by Neil J. Smelser, to provide a comprehensive understanding of this collective experience. This analysis highlights the role of the historical background and socio-cultural context in the establishment of cultural trauma. It also indicates the social agents and cultural elements that contributed to the embeddedness and spread of this phenomenon among the Americans. Finally, it indicates the most prominent collective response of the Americans, and as its consequences.

    Full Text Available This paper analyses the transposition of EU legislation on gender equality at the workplace in the Czech Republic, Hungary, Lithuania and Slovenia, as well as the enforcement powers of their national equality institutions. It does not find significant differences between post- and pre-accession compliance. Overall compliance can be considered good in Hungary, Lithuania, and Slovenia, while it is considerably worse in the Czech Republic – both pre- and post-accession. As an explanation for these variations in legal transposition and enforcement bodies, the paper finds two equifinal paths towards correct transposition of EU gender equality legislation and strong enforcement bodies: either the absence of high adjustment costs, or the combination of strong social democratic governments and NGOs with special expertise in EU gender equality legislation.

    The improvement of preclinical emergency medicine, better surgical and conservative therapies, and the development of intensive care units and specialized centers have improved the survival rate for patients with serious spinal cord injuries. Therefore, more sequelae of chronic spinal cord injuries such as post-traumatic spinal cord cavitations also occur. The first such case was described by Bastian in 1867. Generally, these cavitations were diagnosed from 2 months up to 32 years after the trauma. The overall prevalence of post-traumatic syringomyelia (PTS) is not known; however, with the increasing use of magnetic resonance imaging (MRI), its diagnosis has increased, ranging from 2.3% of paraplegic and tetraplegic patients in 1976 and 3.2% in 1985, to nearly 50% in a selected group of patients in 1991 and 1993. In 1995, a 4.45% incidence was reported. In our clinic we are currently treating 440 cases of syringomyelia, 140 of which are PTS. Several observations suggest more than one potential mechanism for the evolution of a post-traumatic cyst or PTS. Various factors, such as hemorrhage or, in particular, ischemia within the spinal cord, blockage of the cerebrosinal fluid (CSF) pathways around the cord or localized meningeal fibrosis either alone or in combination with other factors, may be involved. Clinically, sensory disturbances, loss of motor function, pain, and modification of the deep tendon reflexes are observed in most patients. On MRI, PTS is seen as a longitudinal, cystic cavity within the spinal cord, giving a hypointense signal on T{sub 1}-weighted images and a hyperintense signal on T{sub 2}-weighted images. For treatment planning it is mandatory to identify the lower and upper end of the PTS on the MRI. (orig.)

    Full Text Available Introduction: Several behavioural changes can occur as a consequence of stroke. A large number of studies have evaluated the frequency and severity of post-stroke depression,  apathy  and  alexithymia  that  result from stroke, however the published data is contradictory.Aims: The aim of this article is to present a literature review of the concepts of depression, apathy  and  alexithymia  and  post-stroke neuroanatomical  findings  that  support these psychopathological observations.Methods: Literature review of selected articles and books deemed relevant by the authors, using Medline/Pubmed database with the combination of the following key-words: “stroke”, “apathy”, “alexithymia”, “depression”,  published  between  1973  and  2013. References of the selected articles and books were also considered.Results  and  Conclusions: After  stroke, many patients are left with variable levels of disability, resulting in a mourning process, and this emotional response is thought to be a normative one to post-stroke problems. It has been understood that the depressive dimension is associated with left frontal lobe functioning  (the  so-called  left  frontal  lobe theory, whereas the apathetic dimension is associated with the basal ganglia. The rate of apathy is lower in patients without previous cerebrovascular  disease;  the  rate  of ‘pure’ apathy (without concomitant depression is twice as frequent as the rate of ‘pure’ depression  (without  concomitant  apathy. Apathetic patients are more frequently and severely depressed and cognitively impaired in comparison to nonapathetic patients. The mechanisms  underlying reduced  emotional  consciousness  and  emotional  blunting following stroke of the MCA are still poorly understood. Apathy and adynamia can be attributed to lesions in the insula and basal ganglia, however reduced emotional awareness can occur as a consequence of changes in

    Post radiation sarcoma is a very rare and invasive malignant tumor that occurs in patients who had radiation therapy 5-10 years ago for primary cancer such as breast cancer, lung cancer or lymphoma. In recent years, the incidence of post radiation sarcoma has increased, as patients survive longer after radiation therapy. We reported a case of surgically confirmed post radiation myxofibrosarcoma from the breast of a 59-year-old woman, with a discussion on the literature.

    Post-conflict economy, rapid urbanization and the ever influential impact of global flows often drive very particular systems of post-conflict infrastructure, ignoring nuances of culture, politics and community. While a large number of analysts today contend that this is a growing symptom of the post-conflict economy, there has arguably always been a fundamental relationship between political articulation and architectural futures.

  18. Post tubal ligation syndrome or iatrogenic hydrosalpinx.

    Gregory, M G

    1981-10-01

    The purpose of this case report is as follows: to attempt to establish an association between the observed increase in hydrosalpinx and the phenomenal increase in surgical sterilization; to present a credible etiology for iatrogenic hydrosalpinx; and to discuss the pathogenesis of a disease process henceforth referred to as post tubal ligation syndrome. A 36-year-old white woman was admitted to Park View Hospital in Nashville, Tennessee on January 7, 1981 for evaluation of continuous lower abdominal pain, abdominal pressure, and dyspareunia for several months. The woman had 2 children who were delivered vaginally. An abdominal tubal ligation was performed for sterilization when she was 27, and vaginal hysterectomy, with anterior and posterior colporrhaphy, was done for symptomatic pelvic relaxation at age 33. Physical examination showed tenderness without palpable masses in the pelvic adnexal areas. Laboratory studies were within normal limits. On January 9, 1981, the patient underwent exploratory laparotomy, and bilateral salpingo-oophorectomy. She was found to have bilateral hydrosalpinx. Historically, hydrosalpinx has been considered an intermediary step in pelvic inflammatory disease. Iatrogenic hydrosalpinx is, in essence, initiated by an initial insult, e.g., tubal ligation, fulguration, or application of a mechanical clip or band. Theoretically, single point interruption of a fallopian tube should produce no ill effects. The popularity and success of tubal ligation attest to single point interruption of an otherwise normal fallopian tube as an innocuous procedure. A schematic drawing is provided of the same tube insulted a 2nd time and consequently the situation is prefactory to development of hydrosalpinx, i.e., a tube lined with secretory epithelium is closed at both ends. Secretion within this closed system will produce dilatation. This "2nd" insult to the normal fallopian tube, post tubal ligation, may take 1 of several forms. The symptoms of iatrogenic

    Full Text Available Abstract Background The increasing focus on achieving a sustained recovery from substance use brings with it a need to better understand the factors (recovery capital that contribute to recovery following treatment. This work examined the factors those in recovery perceive to be barriers to (lack of capital or facilitators of (presence of capital sustained recovery post treatment. Methods A purposive sample of 45 participants was recruited from 11 drug treatment services in northern England. Semi-structured qualitative interviews lasting between 30 and 90 minutes were conducted one to three months after participants completed treatment. Interviews examined key themes identified through previous literature but focused on allowing participants to explore their unique recovery journey. Interviews were transcribed and analysed thematically using a combination of deductive and inductive approaches. Results Participants generally reported high levels of confidence in maintaining their recovery with most planning to remain abstinent. There were indications of high levels of recovery capital. Aftercare engagement was high, often through self referral, with non substance use related activity felt to be particularly positive. Supported housing was critical and concerns were raised about the ability to afford to live independently with financial stability and welfare availability a key concern in general. Employment, often in the substance use treatment field, was a desire. However, it was a long term goal, with substantial risks associated with pursuing this too early. Positive social support was almost exclusively from within the recovery community although the re-building of relationships with family (children in particular was a key motivator post treatment. Conclusions Addressing internal factors and underlying issues i.e. ‘human capital’, provided confidence for continued recovery whilst motivators focused on external factors such as family and

    The paper presents the post-war history of post-traumatic research conducted at the Department of Psychiatry of the Jagiellonian University and the analysis of the main research approaches and selected publications. The time after World War II passed in Poland in two directions: coping with the finished war trauma and simultaneously the experience of communist persecution trauma. First scientific publications appeared in the fifties and were focused on the research of former concentration camps prisoners (KZ-Syndrome). Between 1962 and 1989 a special edition of Przegląd Lekarski, which concentrated entirely on war trauma research, was published. The journal was nominated for the Peace Nobel Prize twice. The research team from the Department of Psychiatry headed by Professor Antoni Kępiński made a very extensive description of KZ-Syndrome issues. The paper summarizes the most important contemporary research findings on psychopathology of KZ-Syndrome (Szymusik), reaction dynamics (Teutsch), after camp adjustment (Orwid), paroxysmal hypermnesia (Półtawska), somatic changes (Gatarski, Witusik). The result of the study was the basis for the development of a methodology and a new look at the classification of the consequences of post-traumatic stress disorder, as well as the development of ethical attitudes towards patients.
