The effect of temperature of the hydrothermal modification on the structure of Rare-earth Y zeolite (REY) was studied by positron annihilation spectroscopy. We measured the positron lifetime spectrum as a function of the temperature (300-800 degree C) of one hour hydrothermal modification for the REY zeolite after through pre-heated dehydration at 150 degree C. All lifetime spectra could be resolved into five components. The fifth lifetime component and its intensity were found to be related to the size and number of the secondary pores. The experimental results showed that the secondary pore in REY zeolite was produced by hydrothermal modification in some temperature range, and the largest size and the greatest quantity of the secondary pores were observed in the sample treated at 500 degree C for 1 hour. The effect of hydrothermal modification on REY zeolite without pre-heated dehydration was also discussed

Full Text Available El edificio Forteza Rey es un fiel exponente de la arquitectura urbana burguesa de comienzos de siglo. Por su dinámica espacial y por su sintaxis decorativa puede englobarse bajo el denominado «modernismo». Tanto la riqueza iconográfica que presenta como su peculiar proceso de construcción, donde aparecen las figuras de artista aún sin estudiar (José Forteza Rey, su hijo Luis, José Alomar otorgan a este edificio un interés especial. Ubicada en el centro urbano de Palma de Mallorca, la Casa Rey está construida sobre un área aproximada de 130 m^ con un desarrollo a partir del nivel de calle de seis plantas más dos secciones subterráneas. Cada planta tiene una distribución espacial similar, acorde con las necesidades de sus ocupantes, aunque en todos los pisos coinciden la disposición de servicios (cocina, baños, despensas, cuarto de servicio, etcétera.

Precisiones sobre la luz en el Pantheon de Roma

Full Text Available El Pantheon de Adriano es una de las obras más celebradas de la historia de la arquitectura. Han sido muchas las cuestiones que han cautivado a cuantos han entrado en él, pero es la luz la que ha acaparado el mayor protagonismo: una vez despojado el edificio de su originaria carga simbólica, la manifestación de su luz interior parece ser el único fin de este inmenso espacio-luz que tanto ha fascinado a arquitectos, historiadores del arte, pintores y fotógrafos. Parece difícil poder aportar nada nuevo. Consciente de ello, el autor del presente artículo sólo pretende apuntar algunas cuestiones sobre distintos aspectos de la luz en el Pantheon que considera que no han sido aún suficientemente desarrolladas: el por qué de la orientación solar y urbana del templo con respecto al eje norte-sur; la reconstrucción de la secuencia de luz y sombra que debió de darse en el recorrido original de acceso al interior del templo; la interpretación del haz de luz ocular como reminiscencia inmaterial del soporte central de las falsas cúpulas etruscas, convertida en una columna de materia sutil que, sin alcanzar nunca la vertical, incide de manera variada sobre los paramentos que conforman el interior.

Buscando luz en la tierra: bajo las bóvedas del Baño Real del Palacio de Comares

Miguel Guitart

2015-05-01

Full Text Available A lo largo de la cultura islámica se han producido soluciones espaciales de enorme riqueza arquitectónica y refinamiento estético, que no necesariamente material. El baño o hammam es con probabilidad uno de los más singulares. Procedente de las pautas establecidas por las termas romanas, estos baños se convirtieron en salas fundamentales de la vida social del mundo islámico. Cabría destacar en España ejem­plos tan relevantes como los Baños de Alí en Jaén del siglo X, el Bañuelo del Albaicín en Granada del siglo XI, o el más representativo de todos ellos, el Baño de Comares en el palacio-fortaleza de la Alhambra del siglo XIV. Todos ellos se caracterizan por sus bóvedas perforadas a modo de grandes moldes de luz que, si bien cumplían una misión funcional como la de introducir luz natural y regular la temperatura y la cantidad de vapor de agua en el interior, también transformaban por completo el espacio por medio de la luz y las sombras, haciendo de estas salas lugares muy característicos de su propia cultura. El hammam del Baño del Palacio de Comares, también conocido como Baño Real por haber sido de uso particular de los Reyes Católicos, se remonta a la época de Yusuf I (1333-1354. El Baño Real o de Comares constituye uno de los espacios de mayor interés dentro del conjunto de la Alhambra, con uno de los hammam en mejor estado de conservación hasta la fecha en Occidente, prácticamente íntegro a pesar de algunas modificaciones estructurales y un mantenimiento más testimonial que funcional. Podríamos asumir que el baño del Palacio de Comares se experimenta desde una doble estrategia: la del estatismo del baño como espacio consolidado y no cam­biante, relacionado por su masa y la condición original de la tierra de la que surge y sobre la que se asienta, que se infunde de vida al ser intervenida por la luz esce­nográfica del filtro de sus bóvedas; y la del movimiento establecido, del recorrido del visitante

El Rey Costales, personaje de la narrativa oral de Zumpahuacán

Urdapilleta Muñoz, Marco

2012-12-01

Full Text Available This paper studies the King of Sacks (Rey Costales, a mythical character in Zumpahuacan’s oral narrative. This so difficult to grasp character, and its protean condition, oriented the research into determining its identity. According the stories, King of Sacks is kind of a «spirit» or «Banshee », but its behavior is that of an «Air”, a Mesoamerican supernatural being. However, its high degree of individualization —as manifested in the consciousness of its pagan status as well as in the lack of links with the atmospheric phenomena affecting crops— required some clarifications. As expected, there is a conflict or symbolic-religious adjustment between Christian beliefs and vernacular beliefs, but above all, a larger cultural realignment revealing the process of looking for balance in collective imagination as a result of a community’s new circumstances, no longer mainly agrarian and indigenous. Beyond this adjustment, the narrative shows the creativity of Zumpahuacan’s inhabitants, projecting their ability to shape their experiences anchored in pre- Hispanic past, but in the light of present experiences and circumstances.

El propósito de este artículo es el estudio del Rey Costales, un personaje mítico de la narrativa oral de Zumpahuacán. Su identidad múltiple, proteica, difícil de asir, orientó la investigación hacia el establecimiento de la identidad del personaje. En los relatos se le refiere como un «espíritu» o «alma en pena», pero su conducta permitió tipificarlo como «aire», un género de seres sobrenaturales mesoamericanos Sin embargo, su alto grado de individualización, manifiesto en la conciencia de su condición pagana, así como la falta de vínculos con los fenómenos atmosféricos que inciden en el cultivo hicieron necesarias algunas precisiones. Éstas mostraron que hay un conflicto o ajuste simbólico-religioso entre las creencias cristianas y las vernáculas, y ante todo un reacomodo

Full Text Available We performed a retrospective study to explore the mortality rates and prognosis of the Reye like syndrome in patients treated at Konya Research and Education Hospital. Twenty two children with ages between 5 months and 7 years old were included in this study. All patients were treated with intensive supportive methods to manage body fluid, blood circulation, respiration, body temperature, and intracranial pressure. The main presenting features were history of fever (72.7%, profuse vomiting (63.6%, abnormal behavior and agitation (77.2%, and sudden onset of unconsciousness (100%. The etiologies of patients included viral illness, gastroenteritis, metabolic disorders, intoxication and hypoxia due to foreign body aspiration. No neurological deficit was seen in the children who survived the disease. In our patients the mortality rate was 31.8%. In conclusion, Reye like syndrome occurs only rarely but should be a part of the differential diagnosis of any encephalopathy of unknown origin and above all if there is a history of ingestion of drugs, previous viral infection and vomiting. Our treatment protocol is safe and effective in children with Reye like syndrome.

We present here the CT findings in 10 patients with Reye syndrome. Acute findings is diffuse cerebral swelling with or without parenchymal low density. The cerebral swelling gradually changed to atrophy. The parenchymal low density predisposes in Lt temporoparietal area. Contrast enhanced CT scan showed no additional finding, except 1 case. The hemorrhagic infarction which has not been reported previously was seen in 1 case and resulted in the most prominent sequela. The sequelae were developed in all atrophic cases. So, the brain CT may be useful in monitoring cerebral swelling, determining treatment plan in acute stage, and in presenting prognosis and sequelae on fellow up CT

An atypical case of Reye's syndrome was reported with emphasis on usefulness of CT for the diagnosis and follow-up study of this disease. The patient was a 13-month-old girl who had been transferred to our hospital because of status epilepticus, a comatous state and a high temperature. She was diagnosed as having Reye's syndrome according to data of liver function tests, findings in CSF and body CT which revealed swelling of the liver with diminished attenuation value suggesting fatty infiltration. However, there were atypical features in this patient: epileptic seizures since age 5 months, no vomiting at the time of onset and no evidence of brain swelling on CT in acute phase. She was discharged 2 months later with impaired neuropsychological functions of marked degree. When she was 2 year-old, she again went into status epilepticus, was comatous and had a high temperature. She was dead when she arrived at emergency room of our hospital. Autopsy findings revealed features of Reye's syndrome as follows: abundant accumulation of small fat droplets without nuclear displacement in the liver, fatty infiltration in the kidney and myocardium, and mild swelling in the cerebral cortex with marked ventricular dilatation. The possibility of recurrence of Reye's syndrome was discussed based on the clinical and autopsy findings. The value of CT in the diagnosis and the follow-up study of this disease was emphasized.

Memory factors in Rey AVLT: Implications for early staging of cognitive decline.

2014-12-01

Supraspan verbal list learning is widely used to assess dementia and related cognitive disorders where declarative memory deficits are a major clinical sign. While the overall learning rate is important for diagnosis, serial position patterns may give insight into more specific memory processes in patients with cognitive impairment. This study explored these patterns in a memory clinic clientele. One hundred eighty three participants took the Rey Auditory-Verbal Learning Test (RAVLT). The major groups were patients with Alzheimer's disease (AD), Vascular Dementia (VD), Mild Cognitive Impairment (MCI), and Subjective Cognitive Impairment (SCI) as well as healthy controls (HC). Raw scores for the five trials and five serial partitions were factor analysed. Three memory factors were found and interpreted as Primacy, Recency, and Resistance to Interference. AD and MCI patients had impaired scores in all factors. SCI patients were significantly impaired in the Resistance to Interference factor, and in the Recency factor at the first trial. The main conclusion is that serial position data from word list testing reflect specific memory capacities which vary with levels of cognitive impairment. © 2014 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

O GPS e a velocidade constante da luz

Full Text Available As transformações de Lorentz e a relatividade especial são incapazes de fornecer uma explicação física realística do comportamento da matéria e da luz. Mostraremos aqui que todos esses fenômenos podem ser explicados usando-se a física de Newton e a conservação da massa-energia, sem apelar para a contração espacial ou a dilatação do tempo. Sabemos que o princípio de conservação da massa-energia requer que os relógios funcionem mais devagar em um referencial móvel, e que os corpos físicos tornam-se maiores devido ao acréscimo do raio de Bohr. Estes resultados nos permitem levantar a seguinte questão: A luz viaja com respeito a quê? Por exemplo, quando nos distanciamos a uma velocidade v de uma fonte emissora de luz, que, por sua vez, se desloca com velocidade c, o movimento relativo da radiação é dado por um deslocamento Doppler. Como podemos explicar logicamente que estes fótons parecem chegar até nós a uma velocidade c e não a uma velocidade (c – v? A explicação convencional remete à relatividade especial, mas isto implica em uma esotérica distorção espaço-temporal, que não é compatível com a lógica. Este artigo fornece uma explicação física de como a velocidade da luz é realmente (c – v com respeito ao observador, mesmo se as ferramentas do observador sempre meçam a velocidade representada pelo número c. Explicamos como este problema é crucial no Global Positioning System (GPS – Sistema de Posicionamento Global e na sincronização dos relógios. As transformações de Lorentz tornam-se desnecessárias. Esta aparente constância da velocidade da luz com respeito a um referencial móvel é a mais fascinante ilusão na ciência.

Serial MRI findings are described in two patients with Reye's syndrome, demonstrating diffuse cortical and white matter changes. In the acute stage, T2-weighted images showed subtle but definite laminar high signal and contrast-enhanced T1-weighted images laminar enhancement, along the entire cerebral cortex bilaterally. In the chronic stage, unenhanced T1-weighted images showed diffuse cortical laminar high signal. These characteristic MRI features seemed very similar to those of laminar cortical necrosis in hypoxic brain damage. MRI also displayed delayed white matter changes with cerebral atrophy. (orig.)

the isthmus led the Colombian elites to rethink other border spaces. The article analyzes the discourse of appropriation of the Amazon territory set forth by President, General, and entrepreneur Rafael Reyes (1849-1921 in speeches lectures, travel diaries, and autobiographical memoirs. On the basis of those materials, the article argues that instead of nationalizing the Amazonian territory, Reyes suggesting incorporating it into the dynamics of global capitalism through the contradictory proposal of an “agricultural export cosmopolis” aimed at exploiting the region’s wealth. The contradictions of a segregationist cosmopolis, as a narrative of globalization in the early 20th century, also led General Reyes to represent the entrepreneurs of the agricultural frontier as “heroes of civilization”, a phrase that betrays the anachronism and irrationalism inherent in the allegedly indestructible rational discourse of civilization in the tropics.

3-hydroxy-3-methylglutaryl-coenzyme A lyase deficiency (HMG-CoA lyase) is an inborn error of ketogenesis and Leucine catabolism. HMG-CoA lyase catalyses the final step in leucine degradation, converting HMG-CoA to acetyl-CoA and acetoacetic acid. Clinical manifestations include hepatomegaly, lethargy or coma and apnoea. Biochemically there is a characteristic absence of ketosis with hypoglycemia, acidosis, hipertransaminasemia and variable hyperammoniemia. The urinary organic acid profile includes elevated concentrations of 3-hydroxy-3-isovaleric, 3-hydroxy-3-methylglutaric, 3-methylglutaconic and 3-methylglutaric acids. Here, we report the case of a 17-year-old girl who presented in both ten months and five years of age a clinical picture characterized by lethargy leading to apnea and coma, hepatomegaly, hypoglycemia, metabolic acidosis, hyperammoniemia, elevated serum transaminases and absence of ketonuria. Diagnostic of Reye syndrome was suggested by hystopathologic finding of hepatic steatosis and clinical and biochemical data. As of 11 years old, laboratory investigations revealed carnitine deficiency and characteristic aciduria. Confirmatory enzyme diagnosis revealing deficiency of HMG-CoA lyase was made in cultured fibroblasts. Our report constitutes an example of the presentation of HMG-CoA lyase deficiency as recurrent Reye-like syndrome.

Administration of Aacetylsalicylic acid in children with viral infections (influence B, chickenpox) can be related with development of Reye syndrome - severe encephalopathy and liver insufficiency with mortality in 50% of cases. During Reye syndrome most important is deficiency of carnitine and hepatocyte damage. Decreased amount of carnitine impairs the energy function of mitochondria and gluconeogenesis as well as production of urea. As a result develops toxic encephalopathy and liver insufficiency. The goal of the research was assessment of efficacy of L-Carnitine, Corvitin and their combination on functional state of liver in experimental model of Reye Syndrome in rats. The study was performed on mature white male Wistar rates with body mass 150-180g. 50 rats were randomly divided into 5 groups (10 rats in each group). The model of Reye syndrome was induced in accordance with A.Vengersky's method. Intraperitoneal administration of 4-pentenoic acid was performed once daily during seven days, the used dosage was 20mg/kg. The treatment of toxic hepatitis was carried with intraperitoneal administration of L-Carnitine 300mg/kg, Corvitine 100mg/kg and concurrent administration of these drugs. Monotherapy with Corvitin and L-Carnitin successfully improved liver function and equally decreased indicators of hepatocyte's cytolyses and increased levels of glucose and urea. The markers of cholestasis was slightly more improved during use of L-Carnitine. Simultaneous use of both drugs was effective in rats with Reye syndrome, indicators of liver damage normalized and herewith, no mortality outcome was observed. The most pronounced hepatoprotective effect of concurrent administration of L-Carnitine and Corvitin may be due to synergic action of these drugs and such regime can be recommended for correction of liver function during Reye syndrome.

The thrombolites across the Permian-Triassic boundary (PTB) are widely distributed in South China. In order to examine the utility of rare earth element and yttrium (REY) in the thrombolites as a proxy of palaeoseawater, the petrographic and geochemical (Sr, Mn, Fe, REY, δ13C, δ18O) features of thrombolites from Cili and Taiping sections are comparatively studied to determine the diagenetic alteration degrees of the thrombolites and the impact of diagenesis on REY concentrations and distribution patterns. The thrombolites from Cili section, digitate in mesoscopic morphology, are latest Permian in age. In contrast, most of the thrombolites in Taiping section are mottled and formed in the earliest Triassic. The variation in thrombolite morphology across the PTB is probably related to increasing amount of metazoan and increasing intensity of bioturbation after the end-Permian mass extinction. Compared to the thrombolites from Taiping section, those from Cili section underwent more extensive diagenetic alteration, which are characterized by more dolomitic content, lower Sr concentrations, more negative δ18O values, and higher Mn/Sr ratios. The REY concentrations are higher in the thrombolites from Taiping section (5-303 ppm, average 48 ppm) than in the thrombolites from Cili section (17-34 ppm, average 25 ppm). Shale-normalized REY distribution patterns of the thrombolites from both sites are similar to those of oxygenated seawater, which are characterized by positive La anomalies (Pr/Pr∗ = 1.1-1.5), negative Ce anomalies (Ce/Ce∗ = 0.2-0.9), and light rare earth element (LREE) depletion. The preserved seawater like REY distribution pattern indicates that diagenesis did not alter the REY distribution patterns. The thrombolite samples from Cili section, compared to the counterparts from Taiping, have less positive La anomaly and less negative Ce anomaly. For the thrombolites from Cili section, a positive correlation exists between Ce anomaly and siliciclastic

Full Text Available Tras la expedición de la Constitución de 1886, la división políticoadministrativa del territorio colombiano permaneció invariable durante 18 años, hasta la creación del Departamento de Nariño, de acuerdo con los parámetros establecidos en la ley. Sin embargo, durante el primer año del gobierno de Rafael Reyes en 1905, fueron instituidos seis nuevos departamentos, para luego, ya en 1908, subdividir el territorio nacional en 34 secciones. El movimiento contrarreformista que siguió a la administración de Reyes en 1909 restableció la división territorial existente antes del Quinquenio, pero ciertas resistencias locales permitieron que algunos de los nuevos departamentos creados recientemente lograran subsistir. El presente artículo constituye una revisión histórica de las transformaciones que sufrió el ordenamiento territorial colombiano durante el gobierno de Reyes, todo con el fin de dar cuenta del papel que cumple el Quinquenio en la definición del mapa político administrativo del país.

The Challenges of Rehabilitating the Hercilio Luz Suspension Bridge

Directory of Open Access Journals (Sweden)

Hermes Carvalho

Full Text Available Abstract The Hercílio Luz suspension bridge, built in 1926, has been out of service since 1991 due to high corrosion levels and structural element impairment. A complete rehabilitation project was developed which included the replacement of the impaired items and foundation strengthening. For this, an auxiliary structure was employed to support the central span during the rehabilitation process. A carefully studied load transfer process, where the central span loading is transferred from the eye-bar towards the auxiliary structure will be performed. For this purpose, a synchronized jacking sequence will be used, which was predefined by means of numerical model analysis. All structural elements had their designs evaluated and some geometric changes were implemented. This paper presents all the methodology developed in the rehabilitation project of Hercilio Luz bridge, as well as the development stages up to the present date.

El objetivo principal consiste en mostrar por qué el silencio constituye en su acción un espacio resonante, esto es: un lugar para la recepción, creación e interpretación de sentido. Con el fin de acometer esta cuestión, en el texto se tratan: relevancia del silencio para las artes según las dos posguerras, percepción del silencio y sensibilización del sentido del oído durante la Gran Guerra, ejercicios de escucha en la vanguardia española, observaciones a la obra 4’33’’ de John Cage y otras interpretaciones contemporáneas de esta pieza. El recorrido que se plantea a lo largo del texto no solo muestra que la aportación de Cage tiene sus matices también subraya la relevancia histórica de las prácticas realizadas en el territorio español y la determinación que supone silencio en las artes y la sociedad, pues desde el s. XX no ha dejado de ser el eje de esa relación dialógica y coextensiva que se da entre ambas.The present paper addresses the issue of the implication of silence on hearing. The main objective is to show why silence is in its action, a resonating space, i.e. a place for the reception, creation, and interpretation of sense. In order to achieve such issue are discussed in the text: the relevance of silence for the arts, according to the two post-war periods, the perception of silence and awareness of hearing during the Great War, the listening exercises in Spanish Avantgarde, observations on John Cage’s 4'33'' piece of work, and other contemporary interpretations of that piece. The text will expose not only that the contribution of Cage has its nuances, but also the historical significance of the practices in the Spanish territory. This highlights the determination that silence implies for the arts and society because, from the Twentieth Century, silence has continued being central to the dialogic and coextensive relationship that

La “Carta abierta a Alfonso Reyes sobre Goethe” de María Zambrano: ¿un caso de irracionalismo poético?

Andreas Kurz

2014-06-01

This article shows that the 1954 dispute between María Zambrano and Alfonso Reyes about Goethe has to be seen as a consequence of the studies of the Spanish philosopher in the field of the interrelation between poetry and philosophy. In the dispute, Reyes seems to represent a rational position, while Zambrano appears to follow an irrational aesthetics originated by German and English romanticism. When applying Karl Popper’s ideas about rationalism and irrationalism, the result is a different constellation: Zambrano as representative of rational and open thinking, Reyes the promoter of a poetic system based solely on the concept of “great man”, developed in literary criticism by Paul Bénichou, which enabled him to see Goethe as a personality that fuses life and work. This interpretation of Goethe is, by the way, predominant in Spanish-speaking cultures, as Udo Rukser showed in his classical study.

The "Caldera del Rey" is a volcanic structure formed by two overlapping maars, The second one (maar that was formed is of greaten dimensions and destroyed part of the first one, Both maars erupted throught a possible fracture N 35 E, which is one of the directions with regional importance in the Archipelago. The eruption, which was very explosive, has been thought to be due in part to the great importance of the gaseous phase of the salic magma and also to the steam produced during the interaction of the magma with underground water. This explosivity can be clearly seen in the cleaf resalte cul out in the "Serie Basáltica Antigua" to some extent penetrated and fragmented by the eruption, The phreatomagmatic character of the eruption is evident because of the existence of accretionary lapilli. The materials emitted are exc1usively of aerial projection: agglomerates, tuffs cinerites. There was no flow of lava. ' Some of the fragments of tuffs as cinerites and pumice are comagmatic. These correspond to salic trachytic phonolitic rocks, which represent one of the last stages of differentiation of the alkaline oceanic magmas.

The municipality of Ubatuba is covered by a rain forest Mata Atlantica preserved in most of the territory. There are many communities that demand electricity in this area, including traditional communities like culture named 'caicara' and the remnants of slaves from Brazil colony named 'quilombos'. They are all very poor and are involved by the interest of environmental agencies. The process of rural electrification in Ubatuba, through the 'Programa Luz para Todos' found difficult to overcome issues of regularization of habitations particularly environmental issues. This work shows that solutions were found through negotiation between the parts, intermediated by an officer known as 'Agente Luz para Todos'. It shows also that without the participation of this agent would have been very difficult exceed some of the barriers. (author)

A 9-month-old male infant was admitted to our hospital on the second day of cold like syndrome because of high fever, convulsion, coma, and decerebrate rigidity. Serum GOT, GPT, LDH, and CPK were markedly elevated. Serum ammonia was slightly increased, and hypoglycemia was present. The cerebrospinal fluid showed no pleocytosis, normal sugar content, but increased protein. Thus we made a diagnosis of clinical Reye syndrome according to the criteria by Yamashita, et al. A CT on the day of admission showed symmetrical low-density areas in the posterior fossa and the regions of thalamus. Ringed enhancements were seen around the areas of low density in the thalamus on the twenty-second hospital day. We consider that these lesions may represent the infarction due to obstruction of the thalamoperforant arteries caused by cerebral edema in the early stage of the disease.

Full Text Available The clinical performance of composite resins is greatly influenced by the quality of the light-curing unit used. The aim of this study was to compare the efficiency of a commercial light-emitting diode (LED with that of a halogen-based light-curing unit by means of dye penetration of a micro hybrid composite resin. The composite resin evaluated was Filtek Z250 (3M Dental. The composite was filled into acrylic moulds that were randomly polymerized for 40 seconds by each of the light-emitting systems: light-emitting diode Ultraled (Dabi Atlante or halogen light Degulux (Degussa Hüls curing units. Immediately after polymerization, each specimen was individually immersed in 1 ml of 2% methylene blue solution at 37°C ± 2°C. After 24 hours, the specimens were rinsed under running distilled water for 1 minute and stored at 37°C ± 2°C at relative humidity for 24 hours. The composite resins were removed from the moulds and individually triturated before being immersed in new test tubes containing 1 ml of absolute alcohol for 24 hours. The solutions were filtered and centrifuged for 3 minutes at 4,000 rpm and the supernatant was used to determine absorbance in a spectrophotometer at 590 nm. To verify the differences between groups polymerized by LED or halogen light t-test was applied. No significant differences were found between composite resins light-cured by LED or halogen light-curing unit (p > 0.05. The commercially LED-based light-curing unit is as effective to polymerize hybrid composite resins as the halogen-based unit.A longevidade clínica das resinas compostas é grandemente influenciada pela qualidade do aparelho fotopolimerizador utilizado.

Martens, R; Hurks, P P M; Jolles, J

2014-01-01

This study investigated psychometric properties (standardization and validity) of the Rey Complex Figure Organizational Strategy Score (RCF-OSS) in a sample of 217 healthy children aged 5-7 years. Our results showed that RCF-OSS performance changes significantly between 5 and 7 years of age. While most 5-year-olds used a local approach when copying the Rey-Osterrieth Complex Figure (ROCF), 7-year-olds increasingly adopted a global approach. RCF-OSS performance correlated significantly, but moderately with measures of ROCF accuracy, executive functioning (fluency, working memory, reasoning), and non-executive functioning (visual-motor integration, visual attention, processing speed, numeracy). These findings seem to indicate that RCF-OSS performance reflects a range of cognitive skills at 5 to 7 years of age, including aspects of executive and non-executive functioning.

Full Text Available Frailty is an ontological part of human experience and characterizes our times. Instability, insecurity, addictions, loneliness, difficulty in finding meaning and perspectives, desire to escape and nostalgia for an unknown and unreal past are predominant in the life of many young people and teenagers. In this context it is possible to consider the global success of the singer Lana Del Rey and of her melancholy and languid lyrics, but also of her videos and photographs, that are expression and celebration of an alleged existential frailty that allows her supporters, especially if adolescents or young women, to identify with her. The study of the phenomenon Lana Del Rey allow to move closer to those feelings of weakness and discomfort that are often hidden, unspoken, confined in the shadows for lack of courage or for shame, but that are, at the same time,  full of grace and of vital energy.  This is one of the tasks of pedagogy.

Full Text Available Standard Economic Accounts for Agriculture and Forestry do not measure the ecosystem services and intermediate products embedded in the final products recorded, and omit the private non-commercial intermediate products and self-consumption of private amenities. These limitations of the standard accounts are addressed by the extended Agroforestry Accounting System, which is being tested at the publicly-owned Dehesa de la Luz agroforestry estate. The extended accounts simulate conservation forestry of holm oak and cork oak for the current as well as successive rotation cycles during which scheduled conservation of the cultural woodland landscape of the Dehesa de la Luz is carried out, improving the natural physical growth of the firewood and cork. The estimated results for 2014 reveal that private ecosystem services make up 50% of the firewood and grazing products consumed; the private environmental income accounts for 13% of the total private income; and the private environmental asset represents 53% of the total opening capital. The net value added is more than 2.3 times the amount estimated using the standard accounts. The landowner donates intermediate products of non-commercial services at a value of 85 €/ha, which are used to enhance the supply of public products.

Full Text Available The Rey Auditory Verbal Learning paradigm is worldwide used in clinical and research settings. There is consensus about its psychometric robustessness and that its various scores provide relevant information about different aspects of memory and learning. However, there are only a few studies in Brazil employing this paradigm and none of them with children. This paper describes the performance of 119 Brazilian children in a version of Rey´s paradigm. The correlations between scores showed the internal consistency of this version. Also, the pattern of results observed was very similar to that observed in foreign studies with adults and children. There was correlation between age in months and recall scores, showing that age affects the rhythm of learning. These results were discussed based on the information processing theory.O paradigma de aprendizagem auditivo-verbal de Rey é utilizado em todo o mundo, tanto em pesquisa quanto na clínica.

Este artigo descreve o desempenho de 119 crianças brasileiras em uma versão do paradigma de Rey. As correlações entre escores mostraram a consistência interna desta versão. Além disso, o padrão de resultados encontrado foi muito similar àquele observado em estudos estrangeiros com adultos e crianças. Verificou-se correlação entre idade em meses e os escores de evocação, mostrando que a idade afeta o ritmo de aprendizagem.

This publication about the Offshore of Point Reyes map area includes ten map sheets that contain explanatory text, in addition to this descriptive pamphlet and a data catalog of geographic information system (GIS) files. Sheets 1, 2, and 3 combine data from four different sonar surveys to generate comprehensive high-resolution bathymetry and acoustic-backscatter coverage of the map area. These data reveal a range of physiographic features (highlighted in the perspective views on sheet 4) such as the flat, sediment-covered seafloor in Drakes Bay, as well as abundant “scour depressions” on the Bodega Head–Tomales Point shelf (see sheet 9) and local, tectonically controlled bedrock uplifts. To validate geological and biological interpretations of the sonar data shown in sheets 1, 2, and 3, the U.S. Geological Survey towed a camera sled over specific offshore locations, collecting both video and photographic imagery; these “ground-truth” surveying data are summarized on sheet 6. Sheet 5 is a “seafloor character” map, which classifies the seafloor on the basis of depth, slope, rugosity (ruggedness), and backscatter intensity and which is further informed by the ground-truth-survey imagery. Sheet 7 is a map of “potential habitats,” which are delineated on the basis of substrate type, geomorphology, seafloor process, or other attributes that may provide a habitat for a specific species or assemblage of organisms. Sheet 8 compiles representative seismic-reflection profiles from the map area, providing information on the subsurface stratigraphy and structure of the map area. Sheet 9 shows the distribution and thickness of young sediment (deposited over the last about 21,000 years, during the most recent sea-level rise) in both the map area and the larger Salt Point to Drakes Bay region, interpreted on the basis of the seismic-reflection data, and it identifies the Offshore of Point Reyes map area as lying within the Bodega Head–Tomales Point shelf, Point

We surveyed for Least Bell’s Vireos (LBVI) (Vireo bellii pusillus) and Southwestern Willow Flycatchers (SWFL) (Empidonax traillii extimus) along the San Luis Rey River, between College Boulevard in Oceanside and Interstate 15 in Fallbrook, California (middle San Luis Rey River), in 2017. Surveys were conducted from April 13 to July 11 (LBVI) and from May 16 to July 28 (SWFL). We found 146 LBVI territories, at least 107 of which were occupied by pairs. Five additional transient LBVIs were detected. LBVIs used five different habitat types in the survey area: mixed willow, willow-cottonwood, willow-sycamore, riparian scrub, and upland scrub. Forty-four percent of the LBVIs occurred in habitat characterized as mixed willow and 89 percent of the LBVI territories occurred in areas with greater than 50 percent native plant cover. Of 16 banded LBVIs detected in the survey area, 8 had been given full color-band combinations prior to 2017. Four other LBVIs with single (natal) federal bands were recaptured and banded in 2017. Three LBVIs with single dark blue federal bands indicating that they were banded as nestlings on the lower San Luis Rey River and one LBVI with a single gold federal band indicating that it was banded as a nestling on Marine Corps Base Camp Pendleton (MCBCP) could not be recaptured for identification. One banded LBVI emigrated from the middle San Luis Rey River to the lower San Luis Rey River in 2017.One resident SWFL territory and one transient Willow Flycatcher of unknown subspecies (WIFL) were observed in the survey area in 2017. The resident SWFL territory, which was comprised of mixed willow habitat (5–50 percent native plant cover), was occupied by a single male from May 22 to June 21, 2017. No evidence of pairing or nesting activity was observed. The SWFL male was banded with a full color-combination indicating that he was originally banded as a nestling on the middle San Luis Rey River in 2014 and successfully bred in the survey area in 2016

El miedo como arma de dominación: admiración, pavor y victoria en la imagen del rey guerrero en el helenismo inicial

Directory of Open Access Journals (Sweden)

Molina Marín, Antonio Ignacio

2014-12-01

Full Text Available The King was the most important figure of all the Hellenistic period. He was an invincible warrior, wise ruler, god, general and medicine man. All these aspects of Hellenistic kingship are well known, however there is one subject that has not been studied by scholars, namely the capacity of Hellenistic kings to scare their enemies with their mere presence. In this paper we analyze stories attaching to Perdiccas, Olympias, Pyrrhus and Alexander the Great. Our opinion is that all these stories are based on the same model, the fight between Achilles and Trojans in the Iliad (XVIII 203-23. The aegis is studied as the mythical justification of the invincibility and terribleness of the kings. Furthermore, we consider the possibility that this phenomenon was associated with the Macedonian kings prior to Alexander.El rey fue la figura más importante de todo el período helenístico. Fue un guerrero invencible, un gobernante sabio, dios, general y curador. Todos estos aspectos sobre la monarquía helenística son bien conocidos, sin embargo hay una cuestión que no ha sido estudiada por los investigadores, es decir, la capacidad de los reyes helenísticos para hacer huir a sus enemigos conmoviéndolos por el miedo con su mera presencia. En este artículo analizamos historias relacionadas con Pérdicas, Olimpíade, Pirro y Alejandro Magno. Nuestra opinión es que todas estas historias están basadas en el mismo modelo, la lucha entre Aquiles y los troyanos en la Ilíada (XVIII 203-23. La égida es estudiada como la justificación mítica de la invencibilidad y terribilidad de los reyes. Además, contemplamos la posibilidad de que este fenómeno estuviese asociado con los reyes de Macedonia antes de Alejandro.

Full Text Available Resumen Josef Svoboda (1920-2002, fue escenógrafo, arquitecto y director artístico de la Linterna Mágica en Praga. Es difícil encontrar en los últimos cien años un escenógrafo que haya aportado tanto al mundo de la escena por su desbordante capacidad creativa. Siempre estuvo dispuesto a resolver problemas con planteamientos novedosos de diseño introduciendo para ello aportaciones tecno­lógicas del momento. Indagó con imaginación sobre otros elementos escenográficos que no fuesen los clásicos diseños basados en corpóreos arquitectónicos, bastidores, etc., pero que determinaban de igual modo un espacio escénico. Amplió la espacialidad en la escena adjudicando capacidades al sonido y a la luz para conseguir una corporeidad psicológica al servicio de la dramaturgia y la estética. Introdujo en el diseño de sus escenografías imágenes con múltiples perspectivas que se percibían con un solo golpe de vista. También utilizó a los espectadores haciéndoles participes de lo que estaba sucediendo en escena. Creó los sistemas de polivisión y poliecrán, que combinaban el teatro y el ballet. Es responsable de la famosa cortina de luz blanca creada por unos focos diseñados por él y que reciben su nombre. Las proyecciones sobre espejos, técnica difícil de manejar en escena, fue otra de las innovaciones que Svoboda manejó magistralmente en sus escenografías. Palabras clave: Diseño escenográfico, Josef Svoboda, poliecrán, focos Svo­boda, cortina de luz, proyecciones sobre espejo permeable, Laterna Magika.

Fire effects on the Point Reyes Mountain Beaver (Aplodontia rufa phaea) at Point Reyes National Seashore, 10 years after the Vision Fire

Science.gov (United States)

Fellers, Gary M.; Osbourn, Michael

2009-01-01

The 1995 Vision Fire burned 5000 ha and destroyed 40% of the habitat of the Point Reyes Mountain Beaver (Aplodontia rufa phaea). Surveys immediately post-fire and in 2000 showed that only 0.4 to 1.7% of Mountain Beavers within the burn area survived. In 2000, dense, ground-hugging Blue-blossom Ceanothus (Ceanothus thrysiflorus) appeared to make coastal scrub thickets much less suitable for Mountain Beavers even though the number of burrows at our 11 study sites had returned to 88% of pre-fire numbers. In 2005 (10 y post-fire), the habitat appeared to be better for Mountain Beavers; Blue-blossom Ceanothus had diminished and vegetation more typical of northern coastal scrub, such as Coyote Brush (Baccharis pilularis) overstory with a lower layer of herbaceous vegetation, had greatly increased; but the number of Mountain Beaver burrows had declined to 52% of pre-fire numbers and there was little change in the number of sites occupied between our 2000 and 2005 surveys. With the expected successional changes in thicket structure, Mountain Beaver populations are likely to recover further, but there will probably be considerable variation in how each population stabilizes.

Full Text Available Light quality (sunlight spectrum management promises to provide a new technological alternative to sustainable production in horticultural crops. However, little information exists about physiological and technological aspects on light quality management in fruit crops. Sunlight composition changes widely in orchard canopies, inducing different plant responses in fruit trees mediated by phytochrome (PHY and cryptochrome (CRY activity. High proportion of far-red (FR in relation to red (R light increases shoot elongation, while blue (B light induces shoot dwarfing. Red and ultraviolet (UV light increases fruit skin anthocyanin synthesis, while FR light shows a negative effect. Red and B light can also alter leaf morpho-physiological traits in fruit trees, such palisade thickness, stomatal aperture, and chlorophyll content. Besides improvement of photosynthetically active radiation (PAR availability, the use of reflective films improves UV and R light proportion, with positive effects on PHY mediated-responses (fruit color, fruit weight, shoot growth, as reported in apple (Malus domestica Borkh., peach (Prunus persica (L.

John Dyson was born on the 7th January 1941 in Meltham Mills, West Yorkshire, England, and later grew up in Harrogate and Leeds. The proudest moment of John's early life was meeting Freddie Trueman, who became one of the greatest fast bowlers of English cricket. John used a state scholarship to study at Kings College London, after hearing a radio lecture by D. M. McKay. He received a first class BSc Special Honours Degree in Physics in 1962, and began a Ph.D. at the University of Manchester Department of Astronomy after being attracted to astronomy by an article of Zdenek Kopal in the semi-popular journal New Scientist. John soon started work with Franz Kahn, and studied the possibility that the broad emission lines seen from the Orion Nebula were due to flows driven by the photoevaporation of neutral globules embedded in a HII region. John's thesis was entitled ``The Age and Dynamics of the Orion Nebula`` and he passed his oral examination on 28th February 1966.

Full Text Available Título en ingles: Influence of light type and intensity on induction and proliferation of somatic embryos in soybean Resumen: La embriogénesis somática representa una alternativa para la regeneración de plantas, sobre la cual influyen diversos factores durante el cultivo in vitro. Entre estos, las condiciones de iluminación durante la formación de embriones somáticos es determinante. Sin embargo, no existen trabajos que refieran el efecto de la luz solar en la formación de embriones somáticos de soya. Este trabajo tuvo como objetivo evaluar el efecto del tipo e intensidad de luz en la formación y multiplicación de embriones somáticos de soya cultivar INCASoy-27. Para ello, cotiledones inmaduros de 3,0-4,0 mm de longitud fueron colocados en medio de cultivo con 40 mg.l-1 de ácido 2,4-diclorofenoxiacético, sacarosa 3% y pH 7,0 en cámaras de crecimiento con luz artificial e intensidades luminosas de 5-10 µmol.m-2.s-1 y 68-73 µmol.m-2.s-1, y en cámaras de crecimiento con luz solar con 50-65µmol.m-2.s-1. El mayor número de cotiledones embriogénicos (95,31 se obtuvo en condiciones de luz artificial con alta intensidad luminosa. La mayor formación de embriones somáticos se obtuvo en luz artificial (9,65 y luz solar (8,45 respectivamente con alta intensidad luminosa. No se encontraron diferencias significativas en la multiplicación de los embriones somáticos, al emplear ambas fuente de luz con alta intensidad luminosa. Esta es la primera referencia sobre formación y multiplicación de embriones somáticos de soya con empleo de luz solar. Palabras clave: Cultivo de tejido; embriogénesis somática; fotoperíodo; Glycine max. Abstract: The somatic embryogenesis represents an alternative for the regeneration of plants, in which influence diverse factors during the cultivation. Among these factors, the conditions of illumination during the induction of somatic embryos are determinant. However, works not exist that refer the effect

Entre Confucianismo y Derechos Humanos: Individuo y Rey

Full Text Available RESUMEN En este artículo se aborda la cuestión de China y los derechos humanos  desde la perspectiva que, según opinión común, constituye la base de esa cultura: el confucianismo. Una perspectiva que es analizada tanto desde su marco contextual como en sí misma, cotejándola con el concepto de derechos humanos. El resultado de todo ello lleva a la conclusión de que los derechos humanos son ajenos al confucianismo y por ello a la cultura china. Sin embargo, no son necesariamente incompatibles con tal perspectiva hasta el punto de que cabria imaginar una síntesis basada en lo que aquí se llamará: el individuo y rey. ABSTRACT In this article we focus on the question of China and human rights from the point of view that, according to common opinion, is at the very basis of Chinese culture: Confucianism. This point of view is analyzed in its contextual frame as well as in itself and related to the human right’s concept. The conclusion is that human rights are foreign to Confucianism and, by extension, to the Chinese culture. Ultimately, however, human rights are not necessarily incompatible with that perspective. It is possible to imagine a kind of synthesis between them, what we’ll call here: the individual and king

Teorías de la luz y el color en la época de las Luces. De Newton a Goethe

Pimentel, Juan

2015-10-01

Full Text Available This article opens with a review of Isaac Newton’s theory of light, focusing on the controversial character of his crucial experiment. It then proceeds to examine certain aspects of his legacy in a century that was perhaps more Newtonian than his own optics. We analyse some of the metaphors connected with light and the symbolic role of light as the metaphor for knowledge. The article concludes with Goethe’s colour theory, his challenge to Newtonian theory, and his reinstatement of human beings and the history of science in order to achieve a better understanding not only of light, the eye and chromatic phenomena, but also of scientific activity as a whole.En este artículo comenzamos por revisar la teoría de la luz de Isaac Newton, centrándonos en el carácter controvertido del experimento crucial. Después nos detenemos en algunos aspectos de su legado en un siglo quizás más newtoniano que su propia óptica, analizando algunas metáforas bajo las que fue entendida la luz, así como el papel simbólico de la luz, metáfora del conocimiento por excelencia. Finalmente repasamos la teoría de los colores de Goethe, su impugnación de la óptica newtoniana y su empeño en recuperar al ser humano y la historia de la ciencia para entender mejor no sólo qué son la luz, el ojo o los fenómenos cromáticos, sino la actividad científica en su conjunto.

Full Text Available New biotechnology applications require in-depth preliminary studies of biodiversity. The methods of massive sequencing using metagenomics and bioinformatics tools offer us sufficient and reliable knowledge to understand environmental diversity, to know new microorganisms, and to take advantage of their functional genes. Villa Luz caves, in the southern Mexican state of Tabasco, are fed by at least 26 groundwater inlets, containing 300–500 mg L-1 H2S and <0.1 mg L-1 O2. We extracted environmental DNA for metagenomic analysis of collected samples in five selected Villa Luz caves sites, with pH values from 2.5 to 7. Foreign organisms found in this underground ecosystem can oxidize H2S to H2SO4. These include: biovermiculites, a bacterial association that can grow on the rock walls; snottites, that are whitish, viscous biofilms hanging from the rock walls, and sacks or bags of phlegm, which live within the aquatic environment of the springs. Through the emergency food assistance program (TEFAP pyrosequencing, a total of 20,901 readings of amplification products from hypervariable regions V1 and V3 of 16S rRNA bacterial gene in whole and pure metagenomic DNA samples were generated. Seven bacterial phyla were identified. As a result, Proteobacteria was more frequent than Acidobacteria. Finally, acidophilic Proteobacteria was detected in UJAT5 sample

Lustosa Klaus Carvalho

2002-01-01

Full Text Available JUSTIFICATIVA E OBJETIVOS: As cânulas de dupla luz podem impor resistências distintas ao fluxo. Esta disparidade pode acarretar ventilação pulmonar não homogênea. O objetivo deste trabalho é comparar o padrão resistivo da cânula de intubação de dupla luz 37 FR com o das cânulas convencionais, utilizadas em nosso meio, quando submetidas a fluxos diferentes. MÉTODO: Foram utilizadas cânulas de intubação orotraqueal com diâmetros internos de 7, 7,5, 8 e 8,5 mm e de dupla luz 37 FR. Os fluxos foram gerados e mantidos por aparelho de anestesia. A pressão resistiva gerada nas cânulas foi aferida por um pneumotacógrafo de orifício variável e convertida para sistema digital. As resistências foram obtidas dividindo-se as pressões medidas pelos fluxos empregados. Os dados foram submetidos à análise de variância (ANOVA e comparados pelo teste de Tukey. RESULTADOS: Foram registradas cinco medidas obtidas aleatoriamente. Todas as cânulas estavam abertas para o meio-ambiente. Resistências estão em cmH2O.L-1.s-1. A resistência aumenta de forma linear com elevação do fluxo. A cânula 37 FR dupla luz mostrou padrão resistivo semelhante ao da cânula com diâmetro interno de 7,5 mm. A oclusão dos ramos da sonda 37 FR eleva significativamente a resistência ao fluxo. Os fluxos de 0,1 a 0,2 L.s-1 resultaram em pressões resistivas semelhantes para uma mesma sonda de intubação, exceto para cânula 7 mm ou para a 37 FR com oclusão (p < 0,001. CONCLUSÕES: Os padrões resistivos da cânulas 37 FR e 7,5 mm mostraram-se bastante próximos. A oclusão de algum ramo da sonda de dupla luz eleva significativamente a resistência, mas de modo indistinto entre ambos ramos para fluxos abaixo de 0,5 L.s-1. Os resultados do presente estudo sugerem a redução de fluxos inspiratórios como parâmetro para diminuir a resistência do sistema de ventilação, quando um dos lumens de um tubo de dupla luz for obstruído.

This study evaluated the specificity and false positive (FP) rates of the Rey 15-Item Test (FIT), Word Recognition Test (WRT), and Test of Memory Malingering (TOMM) in a sample of 21 forensic inpatients with mild intellectual disability (ID). The FIT demonstrated an FP rate of 23.8% with the standard quantitative cutoff score. Certain qualitative error types on the FIT showed promise and had low FP rates. The WRT obtained an FP rate of 0.0% with previously reported cutoff scores. Finally, the TOMM demonstrated low FP rates of 4.8% and 0.0% on Trial 2 and the Retention Trial, respectively, when applying the standard cutoff score. FP rates are reported for a range of cutoff scores and compared with published research on individuals diagnosed with ID. Results indicated that although the quantitative variables on the FIT had unacceptably high FP rates, the TOMM and WRT had low FP rates, increasing the confidence clinicians can place in scores reflecting poor effort on these measures during ID evaluations. © The Author(s) 2014.

A estabilidade de produtos farmacêuticos fotossensíveis é afetada pela luz, que catalisa reações de degradação. O objetivo deste estudo foi avaliar a eficiência de diferentes resinas, coloração, espessura e presença de absorvedores de radiação ultravioleta (UV como promotores de barreira à luz em embalagens plásticas e de vidro para produtos farmacêuticos. A Farmacopéia Americana estabelece limites entre 10 e 25% de transmissão de luz entre 290 e 450 nm para embalagens de medicamentos. Nenhum dos frascos sem coloração mostrou-se adequado, sendo aqueles que apresentaram menor transmissão foram o de vidro e o de politereftalato de etileno (PET, até 350 nm, e o de polietileno de baixa densidade (PEBD no restante do espectro. A amostra de polipropileno (PP apresentou a maior taxa de transmissão até 300 nm, ficando próxima das demais amostras a partir daí. No frasco de PET cristal com absorvedor de radiação UV, observou-se redução significativa nas transmitâncias até 350 nm, chegando à mesma percentagem que o PET sem absorvedor acima deste comprimento de onda. As amostras de PET âmbar, verde e branco apresentaram a melhor barreira à luz dentre os frascos de PET coloridos. As chapas de policloreto de vinila (PVC apresentaramse similares às de PET (tanto cristal quanto coloridas, sendo que as chapas de policloreto de vinila / policloreto de vinilideno (PVC/PVdC e policloreto de vinila / policlorotrifluoretileno (PVC/Aclar apresentaram transmissão similar à do PVC com absorvedor de UV. A embalagem de PP azul apresentou maior barreira que o PP natural, mas não é adequada segundo a Farmacopéia. A espessura se mostrou diretamente proporcional à barreira, tanto nas embalagens de PET quanto nas de vidro. Palavras-chave: embalagens plásticas e de vidro; produtos farmacêuticos; barreira à luz.

Los usos políticos del cuerpo: los dos cuerpos del rey en la filosofía política de Francis Bacon

Full Text Available Como figure destacada en el complejo escenario político de la transición entre la dinastía Tudor y la dinastía Estuardo de Inglaterra, Francis Bacon (1561-1626 adoptó la teoría de los dos cuerpos del rey en sus textos políticos y jurídicos. Su uso de esta teoría tiene una estrecha conexión con conceptos centrales de su filosofía natural que testimonia la profunda conexión que Bacon encuentra entre la política y la naturaleza. En este trabajo, analizaré su utilización de la teoría medieval de los dos cuerpos del rey y la vinculación que esta tiene con el resto de la filosofía baconiana. Tomaré como eje para el análisis su discurso sobre la naturalización de los escoceses nacidos después de la subida al trono de James I, donde Bacon trata el concepto de los dos cuerpos del rey con más profundidad.As a prominent intellectual figure in the complex political arena of England, during the transition from Tudor to Stuart dinasties, Francis Bacon (1561-1626 assumes the medieval King's two bodies theory in his political and juridical writings. His use of this theory is extremely linked to central concepts of his natural philosphy, which testifies to the deep connection that Bacon finds between politics and nature. This paper addresses Bacon's use of the King's two bodies theory and its link to the rest of the Baconian philosophy. The focus of this study will be his discourse on the naturalization of Scots born after James I assumption of power, where Bacon deals more deeply with the King's two bodies theory.

John Pendry John Inglesfield and Pedro Echenique write: John Pendry's 65th birthday is on 4 July 2008, and this issue of the Journal of Physics: Condensed Matter is dedicated to him, with articles by friends, colleagues, and former students. By any standards, John Pendry is a great scientist, who has made—and continues to make—an enormous contribution to physics; the wide range of his interests is reflected in the scope of these articles. Not many scientists can establish a completely new and unexpected area of research, but this has been John's achievement in the last few years in the field of metamaterials, materials whose electromagnetic properties depend on their structure rather than the materials of which the structure is built. In this way, structures with effectively negative electrical permittivity and negative magnetic permeability can be constructed, demonstrating negative refraction; through metamaterials scientists now have access to properties not found in nature, and never previously explored experimentally. Never a week goes by without a potential new application of metamaterials, whether it is perfect lensing, or the cloak of invisibility. This has certainly led to tremendous visibility for John himself, with guest lectures all over the world, and radio and television appearances. John Pendry's first paper was published exactly 40 years ago, 'Analytic properties of pseudopotentials' [1], and since then he has published 310 articles at the latest count. But this first paper already reflected something of the way John works. His PhD project, with Volker Heine at the Cavendish Laboratory, was to interpret the scattering of low energy electrons from surfaces, the technique of LEED which was to become the method of choice for determining surface structure. Although the energy of the electrons in LEED is relatively low—say 50 eV—it is much higher than the energy of the conduction electrons, for which pseudopotentials had been devised, and John

Full Text Available The role of the seed coat in the light sensitivity of seeds of Raphanus sativus L. cv. redondo gigante was analysed by germination tests of intact and naked seeds. Far-red light caused high inhibition of seed germination, while under white and red lights low inhibition was found. Naked seeds presented no light sensitivity with high percentage germination under light and darkness. However, incubation of naked seeds in -0.6MPa polyethylene glycol solution resulted in light inhibition as observed in intact seeds. The analysis of the seed coat transmitted light indicated that the filtered light presented the same photoequilibrium of phytochrome when compared to the white light, with a decrease of only 33% in the light irradiance which reaches the embryo.O papel do tegumento sobre a sensibilidade à luz em sementes de Raphanus sativus L. cv. redondo gigante foi analisado por testes de germinação de sementes intactas e nuas. A luz vermelho-extremo inibiu fortemente a germinação, enquanto as luzes branca e vermelha apresentaram baixa inibição. Por outro lado, sementes nuas não apresentaram sensibilidade à luz, com alta porcentagem de germinação tanto na luz como no escuro. Entretanto, a incubação das sementes nuas em condições de estresse em solução de polietilenoglicol a -0,6MPa, resultou em inibição na luz, como observadas em sementes intactas. A análise da luz transmitida pelo tegumento das sementes indicou que a luz filtrada apresenta o mesmo fotoequilíbrio teórico do fitocromo obtido na luz branca, com um decréscimo em apenas 33% da irradiância que atinge o embrião.

Full Text Available La incidencia de la luz es uno de los aspectos más importantes en el diseño de un invernadero, debido a su función de recrear en su interior un clima diferente al de la latitud en la que se encuentra. Sin embargo, aunque pueda parecer que éste es el factor determinante en la configuración formal de un invernadero, como en todo edificio, existen otros muchos parámetros a considerar. En este artículo se analizan tres invernaderos de referencia posteriores a la Segunda Guerra Mundial, y se observan los aspectos que, en cada caso, han predominado sobre la que sería la forma ideal en lo que respecta a la incidencia de la luz solar. En el primer invernadero, la cuestión se centrará en la imposición de una forma y sistema estructural concretos, en el segundo, en la composición dinámica del conjunto, y en el tercero, en la integración del invernadero en su emplazamiento. Los tres casos tienen en común el compromiso que presenta su solución entre unos y otros parámetros.

Um isolado deste, obtido da cultivar de trigo 'BRS 194', foi repicado por disco micelial em oito meios de cultivo (farinha integral de arroz, aveia, centeio, cevada, trigo, triticale; BSA e extrato de tomate e submetido a três regimes de luz (escuro, fotoperíodo de 12h e luz contínua. As placas permaneceram por 10 dias, em câmara de crescimento sob temperatura de 23-25°C. Em seguida, o número de conídios foi determinado em câmara de Neubauer. O meio de cultivo à base de farinha integral de trigo propiciou a maior esporulação do fungo em todos os regimes de luz, e a maior esporulação ocorreu em regime de luz contínua para todos os meios de cultivos testados. Os meios de arroz e BSA propiciaram uma menor produção de conídios pelo fungo.A set of conditions is necessary for the growth and sporulation of fungi, particularly the composition of culture media, temperature and light. The objective of this research was to determine the ideal culture medium and light regime for the sporulation of P. grisea. Micelial discs of an isolate, obtained from cultivar 'BRS 194' of wheat, were transferred to eight culture media (rice wholemeal, oat, rye, barley, wheat, triticale, PSA and tomato sauce and kept in the dark, under continuous light and 12h of light.

Full Text Available Este trabajo tiene como objetivo primordial comparar y establecer las relaciones de efectividad entre dos técnicas de diseño para el transporte vertical de la luz natural en el interior de las edificaciones. En primer lugar, se diseñó, construyó y utilizó un equipo experimental tipo concentrador domótico, con distribución a través de fibra óptica hacia un espacio interior sin ninguna iluminación natural tradicional, para monitorizar su efectividad por medio de un luxómetro digital y un recopilador de datos (Datalogger de entrada múltiple. En segundo lugar, se monitorizó el rendimiento lumínico de un lucernario tradicional durante un periodo de seis meses. Finalmente, se realizó un estudio por medio de la Simulación Generada por Computadora (SGC, para establecer la relación entre las proporciones tridimensionales de los ductos de luz y la tasa de degradación de la iluminancia obtenida en el interior del espacio arquitectónico. En términos de resultados, el sistema de iluminación natural por fibra óptica (SINFO no alcanza la efectividad lumínica del lucernario, sin embargo, presenta un rendimiento más uniforme y constante. La idea central es utilizar un criterio de comparación validado, tal como el factor de aprovechamiento de luz diurna (Daylight Factor y otras métricas complementarias, para establecer una relación básica de efectividad entre ambas técnicas. Por último, se establecen recomendaciones de diseño con relación a la utilización de cada una de las técnicas.

Serial MRI and X-ray CT scans were performed on a one-year 7-month old girl with Reye-like syndrome. X-ray CT scan revealed marked hemispheric brain edema in the acute stage and moderate ventricular dilatation with diffuse low density area and cortical atrophy in the chronic stage. MRI performed in the chronic stage showed marked progressive changes. Linear high intensity areas were demonstrated on T 2 weighted MRI performed 21 days after the onset. These high intensity areas increased gradually and 60 days after the onset these high intensity areas spread to the grey matter. These high intensity changes seemed to be correspond to cortical necrosis, and those in the white matter to gliosis or degeneration of myelin. (author)

Executive SummaryWe surveyed for Least Bell’s Vireos (LBVI) (Vireo bellii pusillus) and Southwestern Willow Flycatchers (SWFL) (Empidonax traillii extimus) along the San Luis Rey River, between College Boulevard in Oceanside and Interstate 15 in Fallbrook, California (middle San Luis Rey River), in 2016. Surveys were done from March 30 to July 11 (LBVI) and from May 18 to July 30 (SWFL). We found 142 LBVI territories, at least 106 of which were occupied by pairs. Six additional transient LBVIs were detected. Of 20 banded LBVIs detected in the survey area, 9 had been given full color-band combinations prior to 2016, although we were unable to determine the exact color combination of 1 female LBVI. Seven other LBVIs with single (natal) federal bands were recaptured and banded in 2016. Four vireos with single dark blue federal bands indicating that they were banded as nestlings on the lower San Luis Rey River could not be recaptured for identification.Three SFWL territories were observed in the survey area in 2016. Two territories were occupied by pairs and one by a male of unknown breeding status. Both pairs attempted to nest at least once, and both pairs were successful, fledging three young each. Nesting began in early June and continued into July. Brown-Headed Cowbird (Molothrus ater) eggs were not observed in either nest. An additional 12 transient Willow Flycatchers of unknown subspecies were detected in 2016.Two of the five resident SWFLs were originally banded as nestlings on Marine Corps Base Camp Pendleton. One male and one female were banded as nestlings on Camp Pendleton in 2009 and 2011, respectively. One natal male of unknown breeding status, originally banded as a nestling on the middle San Luis Rey River in 2015, was recaptured and given a unique color combination in 2016. This male was later detected on Marine Corps Base Camp Pendleton.

En un contexto signado por el recuerdo de la rebelión que convirtió a Sisenando en el nuevo rey de los visigodos en 631 y la reunión, dos años más tarde, del IV concilio de Toledo, el obispo de Sevilla acentuaba a través de los ejemplos bíblicos la condición humana de todo rey, al indicar las virtudes necesarias pero también los vicios a los que debía hacer frente, con éxito, un verdadero rey.This article focuses on one of the main functions of the Biblical text in the Middle Ages, by analysing the use of biblical models in Isidore of Seville’s Sententiae (c. 633. A study of the explicit references to the Hebrew kings Saul, David and Solomon will allow us to observe how Isidore, an expert in the Sacred Scriptures, uses these biblical figures to teach and communicate to the Visigothic elites his own definition of monarchy. In a context defined by the recent memory of the rebellion that concluded in Sisenand’s rise to the throne in 631 and the Fourth Council of Toledo convened two years later, the Bishop underlines the human condition of every king by discussing the required virtues as well as the vices that a king must confront in order to be considered a true king.

Poreh, Amir; Bezdicek, Ondrej; Korobkova, Irina; Levin, Jennifer B; Dines, Philipp

2016-01-01

The present study describes a novel Forced-Choice Response (FCR) index for detecting poor effort on the Rey Auditory Verbal Learning Test (RAVLT). This retrospective study analyzes the performance of 4 groups on the new index: clinically referred patients with suspected dementia, forensic patients identified as not exhibiting adequate effort on other measures of response bias, students who simulated poor effort, and a large normative sample collected in the Gulf State of Oman. Using sensitivity and specificity analyses, the study shows that much like the California Verbal Learning Test-Second Edition FCR index, the RAVLT FCR index misses a proportion of individuals with inadequate effort (low sensitivity), but those who fail this measure are highly likely to be exhibiting poor effort (high specificity). The limitations and benefits of utilizing the RAVLT FCR index in clinical practice are discussed.

Componentes de condução da luz natural em edifícios multifamiliares: análise de um código de obras

Guilherme Nóbrega de Castro

Full Text Available O uso da luz natural como fonte de iluminação, além dos impactos positivos no bem-estar físico e mental do homem, possui vantagens econômicas. Estas, contudo, dependem da obtenção do nível de iluminação requerido para a tarefa. Neste estudo, o potencial de aproveitamento da luz natural foi analisado considerando-se as dimensões mínimas de sistemas de iluminação natural permitidas para ambientes residenciais, tendo como critério o Código de Obras da cidade de João Pessoa. Os sistemas de iluminação natural analisados consistem em componentes de passagem com componentes de condução. Simulação computacional feita com o software Daysim foi adotada para analisar o comportamento da luz natural. Realizaram-se 480 simulações para cinco ambientes, associando três variáveis no componente de condução: peitoril transparente e opaco (i, componente de condução saliente e encravado (ii, cinco profundidades (iii a três variáveis do entorno: máxima ocupação do solo (i, duas alturas de pavimento (ii, quatro orientações (iii. Os parâmetros de análise foram: iluminância natural útil (INU e autonomia da luz natural (ALN. Com os resultados, percebe-se que os limites mínimos dos critérios do Código não favorecem o aproveitamento da iluminação natural: 40% dos modelos simulados apresentam iluminação natural insuficiente. Os ambientes iluminados através de janelas altas têm os piores resultados.

John came to CERN in 1956 to join the Electronics Group, which was being formed in the SC Division. He thus participated from the beginning in the design, development, production, commissioning and support of electronics for the experiments at the CERN accelerators, initially at the SC and finally at the SPS. From the University of Glasgow he brought his expertise on pulse height analyzers, which were called kick sorters in those days, and did pioneering work with it in the early CERN experiments. He designed read-out systems for successive generations of detectors, such as wire spark chambers, multiwire proportional chambers, calorimeters, etc., often coming up with innovative solutions. Surely one of his finest moments must have been when he worked on complex detector systems, such as liquid argon calo...

Howell, J.A.; Brooks, G.C.; Semenoff-Irving, M.; Greene, C.

2002-01-01

The presence of locally abundant wildlife raises questions about natural regulation and ecological consequences of overpopulation. We sought to establish precise information about population size, structure, and productivity to examine the role of natural regulation in a closed tule elk (Cervus elaphus nannodes) population at Point Reyes National Seashore, California, USA. We estimated an instantaneous exponential growth rate of 0.19 with an adjusted R2 = 0.98 during 1998, 20 years after the elk were introduced. We estimated annual survival for adult cows of nearly 0.95. Calf survival from birth through the rut ending during October-November was 0.85. Male calves exhibited higher mortality than female calves. Cow mortality was associated with the calving season. We measured a 42% increase in cow:calf density from 0.733 ha-1 to 1.043 ha-1 during 1996-1998. We observed a density-correlated reduction in the rate of increase and in the cow:calf ratios prior to high precipitation El Nin??o Southern Oscillation years, 1993, 1996, and 1997, precipitation >1.23 m year-1. Given the high population growth rate and model evaluation of management scenarios, park managers will need to use a suite of approaches, such as contraception and removal, to maintain the elk population at levels at or near the closed-range carrying capacity for years between El Nin??o events.

Obituary: John Louis Perdrix, 1926-2005

Science.gov (United States)

Orchiston, D. Wayne

2006-12-01

John Perdrix, astronomical historian and co-founder of the Journal of Astronomical History and Heritage, died on 27 June 2005. John Louis Perdrix was born in Adelaide, Australia, on 30 June 1926. After studying chemistry at Melbourne Technical College and working in industry, he joined the Commonwealth Scientific and Industrial Research Organisation's Division of Minerals and Geochemistry. In 1974 the Division relocated to the Western Australian capital, Perth, and John spent the rest of his working life there involved in geochemical research. From his teenage years John had a passion for astronomy, which he fine-tuned through the Astronomical Society of Victoria and the Victorian Branch of the British Astronomical Association. He was very active in both groups, serving as President of the former and Secretary/Treasurer of the latter. He was also an FRAS, and a member of the AAS, the BAA parent body, and the IAU (Commission 41)?no mean feat for an Australian amateur astronomer. Throughout his life, he was a strong advocate of close amateur-professional relations. John's main research interest was history of astronomy, and over the years he wrote a succession of research papers, mainly about aspects of Australian astronomy. His well-researched and neatly-illustrated papers on the Melbourne Observatory and the Great Melbourne Telescope are classics, and when the Observatory's future was in the balance they played a key role in the State Government's decision to convert this unique facility into a museum precinct. To support his research activities, John built up an amazing library that developed its own distinctive personality and quickly took over his house and garage before invading commercial storage facilities! Apart from writing papers, John had an even greater passion for editing and publishing. From 1985 to 1997 he produced the Australian Journal of Astronomy, and in 1998 this was replaced by the Journal of Astronomical History and Heritage (JAH2). Both

Re-introduction of tule elk to Point Reyes National Seashore, California, USA

Tule elk (Cervus elaphus nannodes), a subspecies endemic to California, was historically found in large herds throughout much of central and coastal California. Market hunting during the California Gold Rush decimated these herds, and by 1895, only two to 10 elk remained. This remnant group was protected and served as the source for early relocation efforts (McCullough, 1971). Early efforts were generally unsuccessful but did establish a herd in California’s Owens Valley, outside their historical range, in 1933. The herd grew rapidly and supported six controversial hunts between 1943 and 1969. In an effort to limit hunting, concerned preservationists formed the Committee for the Preservation of Tule Elk in 1960. Public pressure resulted in the California State Legislature passing a law in 1971 that halted hunting until either state-wide numbers reached 2,000, or no further unoccupied elk habitat existed. This law prompted the California Department of Fish and Game to begin reintroducing tule elk throughout their former range. In 1976, the U.S. Congress passed a resolution that concurred with state law and directed federal agencies to make lands available for reintroductions within the subspecies’ historical range. Point Reyes National Seashore was identified as a potential translocation site.

Full Text Available En nuestra experiencia como docentes hemos detectado que los fenómenos relacionados con la luz y la visión son de difícil comprensión para las y los estudiantes de cualquier nivel educativo. Con el fin de que los alumnos/as puedan responder adecuadamente a la pregunta acerca de cómo vemos, desde un modelo de la luz como rayo, que permita relacionarla con los objetos y el ojo del observador, formulamos una propuesta innovadora de enseñanza que ensayamos con alumnos/as de 12 años (primer año de la Educación Secundaria Básica, en Argentina. La unidad didáctica tiene como objetivo que las y los estudiantes puedan construir explicaciones progresivamente más potentes acerca de los fenómenos que involucran la percepción de la luz y la visión. Para ello, formulamos actividades que buscan dar cuenta de las concepciones alternativas que los alumnos/as poseen al respecto, muchas de las cuales se constituyen en obstáculos a la hora de aproximarse a los modelos científicos. De allí que la secuencia propuesta está centrada en la identificación y la superación de dichos obstáculos, de manera que las y los estudiantes logren considerar inadecuadas las muy frecuentes concepciones acerca de que vemos porque ";;;;;;algo";;;;;; procede del ojo y que los objetos iluminados emiten luz, en vez de reflejarla. La puesta en práctica de esta unidad didáctica promovió la elicitación de las ideas alternativas de los alumnos/as, en tanto que las actividades desarrolladas permitieron ponerlas en discusión, desestabilizarlas y lograr que los modelos científicos presentados cobraran plausibilidad y potencia explicativa, lo que se evidenció a través de la reformulación de las formas argumentativas usadas para dar cuenta de los fenómenos.

John Strong - 1941-2006

2006-01-01

Our friend and colleague John Strong was cruelly taken from us by a brain tumour on 31 July, a few days before his 65th birthday. John started his career and obtained his PhD in a group from Westfield College, initially working on experiments at Rutherford Appleton Laboratory (RAL). From the early 1970s onwards, however, his research was focused on experiments in CERN, with several particularly notable contributions. The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras (a type of television camera) to record the sparks in the spark chambers. This highly automated system allowed Omega to be used in a similar way to bubble chambers. He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems. In these experiments the Westfield group joined forces with Italian colleagues to measure the form factors of the pion and the kaon, and the lifetime of some of the newly discovered charm particles. Such h...

Our friend and colleague John Strong was cruelly taken from us by a brain tumour on Monday 31st July, a few days before his 65th birthday John started his career working with a group from Westfield College, under the leadership of Ted Bellamy. He obtained his PhD and spent the early part of his career on experiments at Rutherford Appleton Laboratory (RAL), but after the early 1970s his research was focussed on experiments in CERN. Over the years he made a number of notable contributions to experiments in CERN: The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon cameras to record the sparks in the spark chambers; He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems; He was responsible for the second level trigger system for the ALEPH detector and spent five years leading a team that designed and built the system, which ran for twelve years with only minor interventions.

Obituary: John W. Firor (1927-2007)

John W. Firor, a former Director of the High Altitude Observatory and the National Center for Atmospheric Research, and a founder of the Solar Physics Division of the American Astronomical Society, died of Alzheimer's disease in Pullman, Washington on November 5, 2007, he was 80. He was born in Athens Georgia on October 18, 1927, where his father was a professor of agricultural economics. John had an unusually diverse scientific career. His interest in physics and astrophysics began while serving in the army, during which time he was assigned to the Los Alamos National Laboratory, where he guarded highly radioactive materials (many have heard him describe how informal the protections were compared to later times). After his service he returned to college and graduated in physics from Georgia Tech in 1949. He received his Ph.D. from the University of Chicago in 1954, writing his thesis on cosmic rays under John Simpson. John Firor would later remark that: "If you needed cosmic rays to actually do anything, you are sunk." That thought, partly in jest, may help explain his motivation for moving to so many new scientific and management pursuits. John moved from cosmic ray physics to radio astronomy (particularly of the Sun) when he began work at the Carnegie Institution of Washington's Department of Terrestrial Magnetism, where he remained until 1961. During this time, he met Walter Orr Roberts, then the Director of the High Altitude Observatory (HAO) in Boulder, Colorado. HAO was then affiliated with the University of Colorado. In 1959, a movement began to upgrade the atmospheric sciences in the United States by establishing a National Center, where the largest, most important atmospheric research problems could be addressed. Roberts became the first Director of NCAR, as well as the first president of the University Corporation for Atmospheric Research (UCAR), the consortium of universities that was commissioned to manage and staff the new Center. HAO became a

Full Text Available El establecimiento de la plántula es una de las etapas más riesgosas para las plantas, especialmente en zonas áridas y semiáridas donde la sequía y alta radiación solar influyen sobre su emergencia, desarrollo y supervivencia. Se evaluó en invernadero la supervivencia y variables de crecimiento en plántulas sometidas a estrés hídrico y a distintas condiciones de luz, en cinco especies de Acacia (A. aroma, A. caven, A. atramentaria, A. gilliesii y A. praecox que coexisten en los bosques xerófilos de Córdoba, Argentina. Aunque se encontraron diferencias entre las especies (F=5.66, p=0.001, todas tuvieron altos porcentajes de supervivencia en las distintas condiciones de luz y agua, sugiriendo que serían tolerantes al estrés hídrico y podrían establecerse bajo luz o sombra. Si bien todas las especies mejoraron el crecimiento con luz y sin estrés hídrico, A. aroma, A. caven y A. atramentaria mostraron una tendencia hacia un mayor crecimiento en la mayoría de las variables consideradas (F=41.9, p<0.0001; F=7.06, p<0.0001; F=53.59, p<0.0001. Estos resultados sumados a otros ya reportados indicarían una diferenciación de nichos regenerativos favoreciendo la coexistencia regional de estas especies en los bosques xerófilos de Córdoba.

Full Text Available Se llevó a cabo una investigación con el fin de establecer la metodología adecuada para inducir embriogénesis somática en cacao, a partir de semillas maduras. Se estudió el efecto del pH, la luz y la concentración de sacarosa sobre la respuesta embriogénica. Los dos cultivares mostraron diferente respuesta morfogénica y en ambos, estuvo influenciada por el pH, la luz y la concentración de sacarosa. La mejor respuesta embriogénica se obtuvo con un pH de 6,7. El número de embriones producidos fue mayor bajo condiciones de oscuridad que en presencia de luz. La formación de callo y la diferenciación de embriones somáticos estuvo directamente influenciada por la concentración de azúcar en el medio de cultivo. La mayor cantidad de embriones se obtuvo con niveles de sacarosa entre 4% y 6% para el híbrido UF-613xIMC-67 y niveles entre 2% y 4% de sacarosa para el cultivar CATIE-1000. Se presento una embriogénesis somática directa. Los resultados obtenidos sugieren la necesidad de continuar realizando estudios con esta especie.

Para ello me centro principalmente en los ensayos que los tres escritores publicaron en los años veinte y treinta del siglo pasado y destaco las afinidades entre sus planteamientos. Al analizar sus ideas sobre la cultura y la estética del continente concluyo que los tres intelectuales propusieron una misma ordenación del mundo. La utopía occidentalista que ellos anhelaban está marcada por las nociones de consenso y autenticidad y tiene implicaciones políticas. In this article, I study the cultural and aesthetic thought of Pedro Henríquez Ureña, Alfonso Reyes, and Mariano Picón Salas. In order to do this, I take into consideration the essays that the three writers published in the 1920s and 1930s, and I underline the similarities among their ideas. The analysis of their cultural and aesthetic thought shows that the three intellectuals proposed a similar order of the world. The pro-Western utopia that they longed for is marked by the notions of consensus and authenticity and has political implications.

No fueron grandes sumas durante los siglos XII y XIII. Sin embargo, aumentaron mucho en los siglos XIV y XV. Los hospitalarios aragoneses, catalanes y navarros fueron los que más dinero pagaban. En cambio, los hospitalarios castellanos y portugueses dieron menos. La Orden de San Juan envió no sólo dinero sino también caballos, trigo y armas. Los reyes españoles a veces no permitieron que los hospitalarios enviaran las transferencias desde la Península Ibérica al Oriente Latino. The Military Order of Saint John sent large amounts of money from Spain to the Eastern Mediterranean during the Middle Ages. They did not amount to large sums during the twelfth and thirteenth centuries. However, they increased greatly in the fourteenth and fifteenth centuries. The Aragonese, Catalonian and Navarrese Hospitallers were the ones that paid the most money. In contrast, the Castilian and Portuguese Hospitallers gave less. The Order of St. John sent not only money but also horses, wheat and arms.

2009-01-01

John Leroy Climenhaga was born on 7 November 1916 on a farm some 10 km from Delisle, a small town on the Canadian prairies, located about 50 km south-west of Saskatoon, Saskatchewan, and died at his home in Victoria, British Columbia, on 27 May 2008. His parents, Reuben and Elizabeth (nee Bert) Climenhaga, were farming folk, and he carried their honest and open attitude to the world throughout his life. John was the seventh born, and last to die, of their ten children. His father also served as an ordained minister of the Brethren in Christ. In early adulthood, John worked on his father's farm, but then attended the University of Saskatchewan, obtaining a B.A. with Honors in Mathematics and Physics and an M.A. in Physics, in 1945 and 1949 respectively. Between these events he worked as a Physics Instructor at Regina College from 1946 to 1948. In 1949 Climenhaga joined the faculty of Victoria College, as one of only two physicists in a small institution that was then part of the University of British Columbia. He remained in Victoria for the rest of his career, playing a major role in the College's growth into a full-fledged university, complete with thriving graduate programs in physics and astronomy as well as in many other fields. He served as Head of the Physics Department during the 1960s, a period which saw the College become the University of Victoria, with a full undergraduate program in Physics, and campaigned successfully for the establishment of a program in Astronomy, which began in 1965. From 1969 until 1972 he held the position of Dean of Arts and Science, and championed the university's participation in the Tri-University Meson Facility, whose high-current medium-energy beam was ideal for the production and study of mesons and their physics. That period was a turbulent one in the university's history, but John's integrity and his balanced and fair-minded approach to conflicts were of immeasurable importance in steering the young institution through it

Full Text Available The restoration of the Arroyo (stream de los Quiñones (San Sebastián de los Reyes poses a problem whose solution consists in neutralizing the principal sources of its degradation. These sources are: waste water discharges, an urban solid waste dump, situated in the very bed of the stream, and the intensive aggregate extraction which made the stream itself disappear at various points. This article also deals with the recuperation of the surrounding wood in a natural and landscape-friendly way, which would facilitate the access and the walk along the sides of the stream. This would lead to the clearing of other areas of a high ecological value within this municipality.

The orbital debris, space surveillance, and astronomical communities lost a valued and beloved friend when John L. Africano passed away on July 27, 2006, at the young age of 55. John passed away in Honolulu, Hawaii, from complications following a heart attack suffered while playing racquetball, which was his avocation in life. Born on February 8, 1951, in Saint Louis, Missouri, John graduated with a B.S. in Physics from the University of Missouri at Saint Louis in 1973, and received a Master's degree in Astronomy from Vanderbilt University in 1974. John had a real love for astronomical observing and for conveying his many years of experience to others. He encouraged many young astronomers and mentored them in the basics of photometry and astronomical instrumentation. John was author or co-author on nearly one-hundred refereed publications ranging from analyses of cool stars to the timing of occultations to space surveillance. He was honored for his contributions to minor planet research when the Jet Propulsion Laboratory named Minor Planet 6391 (Africano) after him. John held operational staff positions at several major observatories including McDonald Observatory in Texas, Kitt Peak National Observatory in Arizona, and the Cloudcroft Telescope Facility in New Mexico. He observed at numerous observatories worldwide, including Cerro Tololo Inter-American Observatory (CTIO) in Chile, developing a world-wide network of friends and colleagues. John's ability to build diverse teams through his managerial and technical skills, not to mention his smiling personality, resulted in numerous successes in the observational astronomy and space surveillance arenas. As an astronomer for Boeing LTS Inc., he worked for many years at the Advanced Maui Optical and Space Surveillance site (AMOS) on Maui, Hawaii, where he contributed his operational and instrumental expertise to both the astronomy and space surveillance communities. He was also the co-organizer of the annual AMOS

John Locke speaks of personal identity and survival of consciousness after death. A criterion of personal identity through time is given. Such a criterion specifies, insofar as that is possible, the necessary and sufficient conditions for the survival of persons. John Locke holds that personal identity is a matter of psychological continuity. He considered personal identity (or the self) to be founded on consciousness (viz. memory), and not on the substance of either the soul or the body.

John Locke speaks of personal identity and survival of consciousness after death. A criterion of personal identity through time is given. Such a criterion specifies, insofar as that is possible, the necessary and sufficient conditions for the survival of persons. John Locke holds that personal identity is a matter of psychological continuity. He considered personal identity (or the self) to be founded on consciousness (viz. memory), and not on the substance of either the soul or the body.

Bookshelf. John Adams biography

Billinge, Roy

Full text: When John Bertram Adams died on 3 March 1984, CERN lost one of its principal architects. The late Sir John Adams was a very private person who rarely confided in his colleagues. This made the job of his biographer particularly difficult. Michael Crowley- Milling has succeeded admirably, and has performed a very important service. Is it a potted history of CERN, or the story of the building of the PS, or of the SPS? Yes, all of these, but most of all it is a thoughtful and discerning biography and a fitting tribute to a veritable giant of European science and technology. The sub-title,' Engineer Extraordinary' refers not only to John's outstanding ability as a builder of accelerators, but perhaps even more importantly, as a builder of teams and an 'engineer of opinions'. The book describes how John's attention to detail and intuitive engineering skills developed during the early part of his career, when working in radar research, and how he emerged as a natural leader in the building of the CERN PS. Then later, how his statesmanship enabled him to ''...rescue it (the 300 GeV Programme) from seeming political disaster and nurse it through technical problems to a successful conclusion.'' One crucial part of this process described is the visit to CERN in 1970 by Margaret Thatcher, at that time UK Secretary of State for Education and Science, and her subsequent letters of thanks, not only to Bernard Gregory as Director General, but also to John. It is interesting to speculate to what extent the good impression made on that occasion helped many years later, when as Prime Minister Mrs Thatcher decided that Britain should stay in CERN! After the successful commissioning of the SPS, the book goes on to describe the period when the two CERN Laboratories were merged under two Directors General. Unfortunately I found this part a little too low key, given that John and Leon van Hove presided over what was undoubtedly

Rey: a computer code for the determination of the radionuclides activities from the gamma-ray spectrum data

International Nuclear Information System (INIS)

Palomares, J.; Perez, A.; Travesi, A.

1978-01-01

The Fortran IV computer Code, REY (REsolution and Identification), has been developed for the automatic resolution of the gamma-ray spectra from high resolution Ge-Li detectors. The Code searches the full energy peaks in the spectra background as the base line under the peak and calculates the energy of the statistically significant peaks. Also the Code assigns each peak to the most probable isotope and makes a selection of all the possible radioisotopes of the spectra, according the relative intensities of all the peaks in the whole spectra. Finally, it obtains the activities, in microcuries of each isotope, according the geometry used in the measurement. Although the Code is a general purpose one, their actual library of nuclear data is adapted for the analysis of liquid effluents from nuclear power plants. A computer with a 16 core memory and a hard disk are sufficient for this code.(author)

Survey of fishes and environmental conditions in Abbotts Lagoon, Point Reyes National Seashore, California

Science.gov (United States)

Saiki, M.K.; Martin, B.A.

2001-01-01

This study was conducted to gain a better understanding of fishery resources in Abbotts Lagoon, Point Reyes National Seashore. During February/March, May, August, and November 1999, fish were sampled with floating variable-mesh gill nets and small minnow traps from as many as 14 sites in the lagoon. Water temperature, dissolved oxygen, pH, total ammonia(NH3 + NH4+), salinity, turbidity, water depth, and bottom substrate composition were also measured at each site. A total of 2,656 fish represented by eight species was captured during the study. Gill nets captured Sacramento perch, Archoplites interruptus; largemouth bass, Micropterus salmoides; Pacific herring, Clupea pallasi; prickly sculpin, Cottus asper, silver surfperch, Hyperprosopon ellipticum; longfin smelt, Spirinchus thaleichthys; and striped bass, Morone saxatilis; whereas minnow traps captured Sacramento perch; prickly sculpin; and threespine stickleback, Gasterosteus aculeatus. Cluster analysis (Ward's minimum variance method of fish catch statistics identified two major species assemblages-the first dominated by Sacramento perch and, to a lesser extent, by largemouth bass, and the second dominated by Pacific herring and threespine stickleback. Simple discriminant analysis of environmental variables indicated that salinity contributed the most towards separating the two assemblages.

Maps of the Bonsall area of the San Luis Rey River valley, San Diego County, California, showing geology, hydrology, and ground-water quality

Izbicki, John A.

1985-01-01

In November 1984, 84 wells and 1 spring in the Bonsall area of the San Luis Rey River valley were inventoried by U.S. Geological Survey personnel. Depth to water in 38 wells ranged from 1.3 to 38 ft and 23 wells had depths to water less than 10 feet. Dissolved solids concentration of water from 29 wells and 1 spring sampled in autumn 1983 and spring 1984 ranged from 574 to 2,370 mgs/L. Groundwater with a dissolved solids concentration less than 1,000 mgs/L was generally restricted to the eastern part of the aquifer. The total volume of alluvial fill in the Bonsall area is 113,000 acre-feet; the amount of groundwater storage available in the alluvial aquifer is 18,000 acre-feet. The alluvial aquifer is, in part, surrounded and underlain by colluvium and weathered crystalline rock that add some additional groundwater storage capacity to the system. Data in this report are presented on five maps showing well locations , thickness of alluvial fill, water level contours in November 1983 and hydrographs of selected wells, groundwater quality in spring 1960 and graphs showing changes in dissolved solids concentrations of water from selected wells with time, and groundwater quality in spring 1984. This report is part of a larger cooperative project between the Rainbow Municipal Irrigation District and the U.S. Geological Survey. The purpose of the larger project is to develop an appropriate groundwater management plan for the Bonsall area of the San Luis Rey River valley. (USGS)

First John structure resolved: Exegetical analysis, Part 2

Directory of Open Access Journals (Sweden)

Ron J. Bigalke

2013-11-01

Full Text Available Numerous attempts have been suggested regarding the structure of First John. The only nearly unanimous agreement amongst commentators is concerning the prologue (1:1–4 and the conclusion (5:13–21. The lack of unanimity can be frustrating for the majority of those who seek to understand the macrostructure of the First Epistle of John. Consequentially, some commentators have opined that it is impossible to determine a notable structure of First John, and the epistle is thus regarded as a relatively imprecise series of various thoughts that were composed on the basis of mere association. Many exegetes have therefore proposed suggested outlines to aid the understanding of First John as opposed to providing genuine efforts to articulate a discernable structure of the epistle. The final part of this exegetical analysis seeks to demonstrate that exegetes need not succumb to such pessimism because there does appear to be a discernable structure to First John. Providing and stating resolve concerning the First John structure is fundamental for understanding the revealed contents of the epistle.

Alternative Constructions of Treason in the Angevin Political World: Traïson in the History of William Marshal

Directory of Open Access Journals (Sweden)

Stephen D. WHITE

2007-05-01

Full Text Available After some nobles and other fighting men surrendered Rochester castle to King John in 1215, John wanted to hang the nobles but refrained from doing so on the advice of one of his military captains. Would hanging the nobles for making war on the king have been lawful? This question about the law of treason has provoked inconclusive debate among historians who have sought to determine whether, in this period, making war against the English king was legally classified as lèse-majesté (crimen laesae majestatis, proditio or infidelitas. This article, however, asks whether the nobles whom John wanted to hang were guilty of traïson, as this vernacular term was used in the History of William Marshal (c. 1230. On this basis, the paper concludes that in all probability, the nobles who held Rochester against the king would not have been condemned as traitors, at least by their aristocratic peers.Cuando en 1215 ciertos nobles y otros combatientes se rindieron y entregaron el castillo de Rochester al rey Juan éste quiso colgarles, pero el consejo de uno de sus nobles le hizo absternerse. ¿Habría sido legítimo condenar a la horca a los que habían guerreado contra el rey? Cuestiones relativas al derecho de traición al intentar determinar si la guerra contra el rey de Inglaterra fue considerada en la época un crimen laesae majestatis, proditio, o infidelitas, según la definición que dan a estos términos las fuentes latinas, han suscitado debates interminables entre los historiadores. Este artículo, por el contrario, se pregunta si los nobles que el rey Juan deseaba colgar eran o no culpables de traición, en el sentido vernáculo del término que es usado en L’histoire de Guillaume le Maréchal (hacia 1230. Sobre esta base, la conclusión del artículo es que los nobles que ocuparon el castillo de Rochester, casi con total seguridad, no habrían sido condenados como traidores, al menos por sus pares.

Full Text Available This article studies the role of the nobility in the XV century military expansion of the Crown of Aragon, through the particular case of the valencian nobility and the Alphonse V the Magnanimous's war cycle betwen the years 1420 and 1448. If s first analyzed the development of the royal campaigns. Then, the Valencian lineages are identified, also precising their particular degree of involvement in the royal wars. The study is based upon the registers of the Royal Treasury and Cancillery, supplemented by notarial and judicial records, and the chronicles. The militarization of the nobility was unequal. The majority of the noblemen were involved occasionally in the royal wars, more as an social obligation than a professional committment. The professionalization only attained a minority of lineages, attached to the royal household: they constituted the military king´s affinity, most of them coming from the low urban nobility —most of them also being youngers sons, bastards or belonging to secondary branches.

Sayonara Michelle Mesquita Paiva Paiva

2017-08-01

Full Text Available RESUMO: O concreto por ter ampla utilização na construção civil, é constantemente objeto de pesquisas entre os estudiosos, sempre com o intuito de melhorar suas propriedades e aumentar seu uso nas edificações. O concreto é uma mistura de aglomerantes, agregados, aditivos e água. O concreto trouxe para a construção civil a possibilidade de projetar e executar as mais variadas formas, no entanto sempre foi um desafio para arquitetos e engenheiros a questão da iluminação nos ambientes fechados. Foi diante dessa dificuldade que surgiu um novo material no mercado, um concreto capaz de aliar as propriedades do concreto convencional com a iluminação natural, o Concreto Translúcido. O Concreto Translúcido é composto por concreto convencional e fibras ópticas, são essas fibras que permitem a passagem de luz através do concreto, conferindo assim um material favorável ao meio ambiente, tendo em vista que o consumo de energia pode ser reduzido. Este trabalho tem por objetivo mostrar as características desse novo material, suas vantagens e desvantagens e suas aplicações no Brasil e no mundo.

Simulação computacional integrada para a consideração da luz natural na avaliação do desempenho energético de edificações

Directory of Open Access Journals (Sweden)

Evelise Leite Didoné

Full Text Available A luz natural é uma importante estratégia para redução do consumo de energia em edificações. Para sua previsão, recomenda-se a utilização de programas de simulação que empregam arquivos climáticos e processam as simulações com o conceito do Daylight Coefficients. O EnergyPlus, programa para simulação termoenergética, é uma dessas ferramentas. Porém, este software possui limitações no módulo de iluminação natural que superestimam a luz natural em ambientes internos. Para contornar essas limitações, o presente trabalho propõe uma metodologia para avaliação da eficiência energética, considerando o aproveitamento da luz natural, através da utilização de dois programas. A metodologia consiste na avaliação do desempenho luminoso e energético através de simulação com os programas Daysim e EnergyPlus. O Daysim produz um relatório que descreve o controle da iluminação artificial que é utilizado na simulação energética do EnergyPlus, que calcula o consumo energético final dos ambientes analisados. Os resultados indicam que a metodologia proposta mostrou-se adequada para suprir as limitações do EnergyPlus e para a avaliação da eficiência energética em edificações, considerando o aproveitamento da luz natural. Este trabalho mostra um caminho alternativo e confiável para a consideração do aproveitamento da iluminação natural na avaliação da eficiência energética de edificações.

Kamila Mendonça de Lima

Full Text Available O projeto de janelas considera os efeitos do meio externo, tais como o ganho de calor solar e a iluminação natural, os quais podem ser conflitantes. Este trabalho avalia o desempenho de diferentes alternativas de sistemas de janela para suporte a decisões de projeto quanto ao equilíbrio de ganhos de luz e calor no ambiente interno, com ênfase no uso de escritório no contexto do clima quente e úmido. Para isso, simulações computacionais integradas utilizando os programas Daysim e EnergyPlus foram realizadas, considerando-se o acionamento das lâmpadas apenas quando a luz natural não é suficiente para atender ao uso do ambiente. Foram variados o percentual de área de abertura, o tipo de vidro e o ângulo de sombreamento, simultaneamente, identificando-se soluções de compromisso quanto aos critérios de disponibilidade e uniformidade da luz e demanda de energia elétrica no ambiente. O controle solar pelo uso de dispositivo de proteção solar apresentou resultados substancialmente melhores que o controle solar apenas pela redução da transmissão da radiação solar do vidro. A avaliação realizada contribui para o aprofundamento da compreensão do impacto de diferentes variáveis de projeto nos fenômenos que caracterizam o desempenho da abertura de uma edificação.

When Rey-Osterrieth’s Complex Figure Becomes a Church: Prevalence and Correlates of Graphic Confabulations in Dementia

Directory of Open Access Journals (Sweden)

Oriana Pelati

2011-11-01

Full Text Available Verbal confabulation (VC has been described in several pathological conditions characterized by amnesia and has been defined as ‘statements that involve distortion of memories’. Here we describe another kind of confabulation (graphic confabulation, GC, evident at the recall of the Rey-Osterrieth complex figure (ROCF. In a retrospective study of 267 patients with mild-to-moderate dementia, 14 patients (4.9 % recalled the abstract ROCF as drawings with recognizable semantic meaning. VC was evident at the story recall test in 19.8% of the study participants. VC and GC were homogeneously distributed among the different types of dementia. VC has been proposed to originate from complex interactions of amnesia, motivational deficit and dysfunction of monitoring systems. On the contrary, GC seems to be the result of a deficit in visual memory replaced by the semantic translation of isolated parts of the ROCF along with a source monitoring deficit.

John Calvin and John Locke on the Sensus Divinitatis and Innatism

Directory of Open Access Journals (Sweden)

J. Caleb Clanton

2017-02-01

Full Text Available Inheritors of the Calvinist Reformed tradition have long disagreed about whether knowledge of God’s nature and existence can be or need be acquired inferentially by means of the standard arguments of natural theology. Nonetheless, they have traditionally coalesced around the thought that some sense or awareness of God is naturally implanted or innate in human beings. A root of this orientation can be found in John Calvin’s discussion of the sensus divinitatis in the first book of The Institutes of the Christian Religion. This paper outlines a pedagogical strategy for organizing and evaluating Calvin’s treatment of the sensus divinitatis, chiefly by putting it in tension with John Locke’s polemic against innatism in Book I of An Essay concerning Human Understanding. I begin by reconstructing Calvin’s depiction of the sensus divinitatis, as well as his case for thinking that it is innate. I then explain how Locke’s critique of innatism offers a fairly direct response to Calvin and, hence, a useful framework for exploring the limits of Calvin’s treatment of the sensus divinitatis.

Obituary: John J. Hillman, 1938-2006

Science.gov (United States)

Chanover, Nancy

2007-12-01

John J. Hillman, a dedicated NASA civil servant, spectroscopist, astrophysicist, planetary scientist, and mentor, died on February 12, 2006 of ocular melanoma at his home in Columbia, Maryland. His professional and personal interests were wide-reaching and varied, and he devoted his career to the advancement of our understanding of the beauty and wonder in the world around us. His love of nature, art, and science made him a true Renaissance man. John was born in Fort Jay, New York, on November 22, 1938, and was raised in Washington, D.C. He received his B.S., M.S., and Ph.D. degrees in Physics from American University in 1967, 1970, and 1975, respectively. He began working at NASA's Goddard Space Flight Center, then in its infancy, in 1969, juggling a full-time position as a Research Physicist, the completion of his M.S. and Ph.D. degrees, and a young family. His background in molecular spectroscopy enabled him to apply his skills to numerous disciplines within NASA: infrared and radio astronomy; electronic, vibrational, and rotational structure of interstellar molecules; solar and stellar atmospheres; and planetary atmospheres. He published more than 70 journal papers in these disciplines. He was a frequent contributor to the Ohio State University International Symposium on Molecular Spectroscopy, and possessed a rare ability to bridge the gap between laboratory and remote sensing spectroscopy, bringing scientists from different disciplines together to understand our Universe. The last fifteen years of John's career were devoted to the development of acousto-optic tunable filter (AOTF) cameras. He championed this technology as a low-cost, low-power alternative to traditional imaging cameras for in situ or remotely sensed planetary exploration. It was within this context that I got to know John, and eventually worked closely with him on the demonstration and application of this technology for planetary science using ground-based telescopes in New Mexico, California

Diet of lowland tapir (Tapirus terrestris) in El Rey National Park, Salta, Argentina.

Science.gov (United States)

Chalukian, Silvia C; de Bustos, M Soledad; Lizárraga, R Leonidas

2013-03-01

Lowland tapir (Tapirus terrestris) is the largest herbivore in the Neotropics and, in Argentina, it inhabits a variety of habitats from 100 to 2100 m asl. Lowland tapirs importantly influence their habitat structure because they are selective browsers, seed predators and long-distance seed dispersers. However, increased knowledge of tapir ecology is necessary to support the conservation and management of the species in natural and human-modified environments. Between Jun 2002 and Dec 2008 we assessed the tapir's diet in El Rey National Park, Salta, northwestern Argentina. We collected fresh feces and recorded browsing signs, and we recorded direct observations of tapirs while they were feeding. We analyzed 88 feces samples that had been dried and subsequently weighed. Feces were dominated by fibers and leaves (84.09%), while fruit parts represented a small proportion of the weight (15.91%). During the dry months, a greater percentage of seeds were found in the feces, mainly due to the availability of 3 species of Fabaceae fruits. We recorded a total of 57 plant species from 26 families. Tapirs are adapted to extreme habitats, switching their diet from frugivory to herbivory when fruits are scarce. Considering this, forest remnants and even secondary growth fields should be protected from deforestation. © 2012 Wiley Publishing Asia Pty Ltd, ISZS and IOZ/CAS.

A repeated observation during memory assessment with the Rey Auditory Verbal Learning Test (RAVLT) is that patients who spontaneously employ a memory rehearsal strategy by repeating the word list more than once achieve better scores than patients who only repeat the word list once. This observation led to concern about the ability of the standard test procedure of RAVLT and similar tests in eliciting the best possible recall scores. The purpose of the present study was to test the hypothesis that a rehearsal recall strategy of repeating the word list more than once would result in improved scores of recall on the RAVLT. We report on differences in outcome after standard administration and after experimental administration on Immediate and Delayed Recall measures from the RAVLT of 50 patients. The experimental administration resulted in significantly improved scores for all the variables employed. Additionally, it was found that patients who failed effort screening showed significantly poorer improvement on Delayed Recall compared with those who passed the effort screening. The general clear improvement both in raw scores and T-scores demonstrates that recall performance can be significantly influenced by the strategy of the patient or by small variations in instructions by the examiner.

In this first John Adams' Memorial Lecture, an outline is given of his work, especially from the beginning of CERN in 1952 until his death in 1984. The historical survey covers John Adams' technical and managerial contributions to the development of CERN and its accelerators, as well as to fusion research in Britain and Europe. Exemplified by his role as member and president of the International Committee for Future Accelerators (ICFA), Adams' interest in international co-operation is also stressed. In the spirit of this great European, arguments are given for CERN to continue to be the first-rate high-energy physics laboratory which it has been in the past. (orig.)

Abstract - John Banville’s talent as a prose stylist is widely recognized. The polished elegance of his phrases constitutes a continuing and fascinating challenge for his translator, due to the intricacies of the source text, its manifold registers and lexical choices. In his novel The Infinities, in Italian Teoria degli Infiniti, John Banville takes cue from Kleist’s Amphytrion to devise a novel where classicality interweaves with science and science fiction through the invention of a world ...

This article relates the development of a research about low cost for rural electrification projects, which have been used like a base to develop a technical analysis in whole projects of the program 'Luz para Todos'. This program was made in 2002 with the purpose to offer electricity for whole people in Brazilian rural area. This method was developed seeking in to achieve cost reduction in the planning made by electric companies in Sao Paulo state. At first, were analyzed the rural electric projects made by electricity companies in the program 'Luz da Terra', in front of to the commitment in achieving cost reduction in the rural electric projects. The program 'Luz da Terra' was made whit a social purpose and it was developed in the whole Sao Paulo state, during 1996 until 2004. One of the main demands to achieve reasonable costs and to allow the program's viability was the previous analyses of rural distribution projects, before them changing to work of electricity, checking out if they had well defined. social, technical and economics methods. For that, were chosen quantitative and non-quantitative indicators, agreement whit a comparative analysis of each company performance in the program 'Luz da Terra', in agreement whit historical series, based on the group of the final result of each distribution electricity project. In a second moment, the same methodology was adjusted to confront the plans data of each company's future works in the program 'Luz para Todos', using the results of the first program. The research allowed the identification of some planner's tendencies when developing from a more rigorous model of low cost, like was the program 'Luz da Terra', to the actual program 'Luz para Todos'. Applied to all companies in the Sao Paulo state, the study served as a support to renegotiate budgets, what provided savings of more than US$ 10,000.000 in a total of 42

John Aldrich was born in Providence, Rhode Island, on 23 February 1906, and went to the Providence public schools. He developed a broad interest in natural history at an early age, being stimulated by his mother, a kindergarten teacher, who introduced him to nature books. His interest was strengthened by Harold L. Madison, Director of the Park Museum in Providence, an Associate ( = member) of the AOU. As a high school student, John taught nature study at the Rhode Island Boy Scout Camp in summers. John was President of his class at Classical High School, and manager of the school's football team in his senior year. Also in that year, 1923, John published his first paper, a note in Bird-Lore on the occurrence of the Mockingbird in Rhode Island. That paper is a literary gem, showing that his skill in writing developed as early as his knowledge of birds. His early interest in football continued as well; he was a devoted fan of the Washington Redskins in his later years.

Filmes Kodak Ultra-speed e Ektaspeed Plus foram colocados no interior de uma câmara desse tipo e submetidos durante cinco minutos às condições de iluminação natural e artificial em que elas são rotineiramente utilizadas. Depois disso, os filmes foram processados pelo método temperatura-tempo em câmara escura convencional, juntamente com filmes dos mesmos grupos de sensibilidade que serviram como controle. Os valores densitométricos obtidos das amostras dos filmes foram analisados pelo teste de Mann-Whitney que indicou ao nível de 1% de significância, que os filmes submetidos às condições da câmara portátil apresentaram densidades de base + véu maiores em relação aos grupos controle. Os resultados mostraram que o filme Ektaspeed Plus apresentou valores maiores de densidade de base + véu em comparação com o filme Ultra-speed e que, embora o acrílico filtre a luz de forma similar ao filtro Kodak GBX 2, a maior intensidade de luz no interior da câmara escura portátil ocasionou o aumento na densidade de base + véu.

ínsula Antartica. A pesar de que ambos habitats se caracterizan por ser fríos y con temperaturas congelantes, existen importantes diferencias microclimáticas entre estos habitats durante el período de crecimiento. Por ello, sería esperable encontrar importantes diferencias en la respuesta del aparato fotosintético a factores abióticos entre poblaciones antarticas y andinas de C. quitensis. Estudiamos la relación de la fotosíntesis neta con la temperatura foliar y la intensidad lumínica en dos poblaciones de C. quitensis, una proveniente de La Parva en Los Andes de Chile central y la otra de la Isla Rey Jorge, en la Antartica marítima. Plantas de ambas poblaciones fueron crecidas en laboratorio a 15 °C y 250 μmol fotones m-2 s-1, con un fotoperíodo de 16/8 h luz/oscuridad. Veinte plantas de cada población fueron transferidas a una cámara a 4 °C, con las mismas condiciones de luz y fotoperíodo antes mencionadas, de modo de evaluar la capacidad de aclimatación de la fotosíntesis. A 15 °C, las poblaciones presentaron diferencias en su temperatura foliar óptima para la fotosíntesis. Estos óptimos fueron 24,0 °C en individuos provenientes de los Andes y 18,6 °C en individuos de la Antártida. En contraste, los individuos antarticos mostraron la más alta tasa de fotosíntesis neta bajo ambos tratamientos de temperatura, con puntos de compensación y saturación más bajos. Los individuos antarticos tuvieron mayor capacidad fotosintética a menores temperaturas que los individuos andinos. Nuestros resultados sugieren que C. quitensis ha adaptado el desempeño fotosintético de individuos creciendo en diferentes localidades a las condiciones climáticas predominantes en dichas localidades. Las diferencias en las respuestas fotosintéticas a la temperatura y a la luz son discutidas en relación a la diferenciación ecotípica entre las dos poblaciones estudiadas

Anamnesis and the Silent Narrator in Plato and John

Directory of Open Access Journals (Sweden)

George L. Parsenios

2017-03-01

Full Text Available The Gospel of John is often compared to the dialogues of Plato by those who connect Johannine theology and Platonic philosophy. The comparison operates on the level of ideas. The present paper does not ignore issues of theology and philosophy but grounds a comparison of John and Plato first and foremost on the literary level. In several key places in John 1, 3, and 14, the Johannine narrator recedes from view and is unexpectedly silent where one would expect a narrator’s comment to organize the conversations and interactions between characters in John. Plato also renders the voice of the narrator silent in a dialogue like the Theaetetus. This paper argues that John and Plato both suppress the narrator’s voice in order to further their anamnetic efforts and to make later generations not only readers but participants in their original conversations.

Origen del Palacio de Pedro I en el Alcázar de Sevilla: el mirador hoy llamado de los Reyes Católicos

Full Text Available This study originated with the search for the possible initial site of the main door of the Old Chapel, which, following its restoration and study, turned out to be older than the rest of the Mudéjar palace of King Pedro I (Seville, 1365. During this investigation, and based on recent studies carried out as the result of several previous restorations, the author realized that this door was not relocated from another place. It had formed part of the earlier Gothic palace to which the construction of Pedro I’s palace was attached at this juncture, with several rooms from basement to upper balcony predating the Mudéjar building, thereby concluding that it must have been the work of his father, King Alfonso XI.El presente trabajo, se inicia con la búsqueda del emplazamiento que pudo tener la gran puerta de la Antigua Capilla, de la que, tras su restauración y estudio, sabemos que existía con anterioridad a la obra mudéjar del palacio de Pedro I en Sevilla en 1365. En esa búsqueda, y apoyándonos en los distintos estudios que se vienen realizando con motivo de restauraciones recientes, hemos llegado a la conclusión de que no se trata de carpintería reutilizada, sino que es toda la construcción de esa parte del palacio, adosada al anterior palacio gótico, y con distintas estancias desde el sótano hasta el Mirador, la que ya existía con anterioridad al rey Don Pedro, y con toda probabilidad obra de su padre el rey Alfonso XI, como se concluye en este artículo.

Full Text Available Light is a limiting factor for fern stablishment because it controls germination of light sensitive spores. The aim of this work was to study the effect of light levels on spore germination in two ornamental ferns native to the Atlantic forest, under natural conditions. Cyathea delgadii is a tree fern and Blechnum brasiliense, a subarborescent fern. The effect of light levels was analyzed in April and July/2003, in Florianópolis, Santa Catarina state, Brazil. Sterilized spores were sown in Erlenmeyer flasks containing mineral culture medium with macronutrients, iron, and benomyl 0.01%. The Erlenmeyer flasks were kept in 50 cm³ boxes covered with black shade netting, which gave 5, 22, 42, and 62% natural light. Irradiance and temperature were scored daily at 14:00 h during the study period. Higher percentages of germination were observed at 5 and 22% light for both species. Germination of Cyathea delgadii spores at 22% light reached 76% and mean germination time was 19.7 days; at 5% light, germination reached 83.5% and mean germination time was 20.16 days. Germination of Blechnum brasiliense at 22% light reached 76% and mean germination time was 9.06 days; at 5% light, germination reached 84% and mean germination time was 13.18 days. The highest light levels inhibited spore germination and the gametophytes died during the test period.Luz é um dos fatores limitantes para o estabelecimento das pteridófitas, pois controla a germinação de esporos fotossensíveis.

Full Text Available La idea de cambio radical en las organizaciones se ha discutido mayormente desde dos posturas teóricas. Una, impulsada por las teorías adaptacionistas, sostiene que el cambio es posible porque el ambiente no es algo inmodificable y los gerentes pueden ser agentes activos del mismo. La otra, soportada por la teoría de la ecología poblacional, sostiene que el cambio es imposible dada la inercia estructural a la que se enfrenta toda organización. En este trabajo se revisan cada una de estas aproximaciones y se discuten las implicancias de la teoría de la ecología poblacional a la luz de las teorías adaptacionistas.

2005-12-01

John Daniel Kraus, 94, of Delaware, Ohio, director of the Ohio State University "Big Ear" Radio Observatory, physicist, inventor, and environmentalist died 18 July 2004 at his home in Delaware, Ohio. He was born on 28 June 1910 in Ann Arbor, Michigan. He received a Bachelor of Science in 1930, a Master of Science in 1931, and a PhD in physics in 1933 (at 23 years of age), all from the University of Michigan, Ann Arbor. During the 1930s at Michigan, he was involved in physics projects, antenna consulting, and in atomic-particle-accelerator research using the University of Michigan's premier cyclotron. Throughout the late 1920s and the 1930s, John was an avid radio amateur with call sign W8JK. He was back on the air in the 1970s. In 2001 the amateur radio magazine CQ named him to the inaugural class of its Amateur Radio Hall of Fame. He developed many widely used innovative antennas. The "8JK closely spaced array" and the "corner reflector" were among his early designs. Edwin H. Armstrong wrote John in July 1941 indicating in part, "I have read with interest your article in the Proceedings of the Institute on the corner reflector...Please let me congratulate you on a very fine piece of work." Perhaps John's most famous invention, and a product of his intuitive reasoning process, is the helical antenna, widely used in space communications, on global positioning satellites, and for other applications. During World War II, John was in Washington, DC as a civilian scientist with the U.S. Navy responsible for "degaussing" the electromagnetic fields of steel ships to make them safe from magnetic mines. He also worked on radar countermeasures at Harvard University's Radio Research Laboratory. He received the U.S. Navy Meritorious Civilian Service Award for his war work. In 1946 he took a faculty position at Ohio State University, becoming professor in 1949, and retiring in 1980 as McDougal Professor Emeritus of Electrical Engineering and Astronomy. Even so, he never retired

Full Text Available The study of Alejandro de Humboldt's transit through Spain and particularly Madrid, has been one of the forgotten aspects of his historiography. The reasons that would explain the approval by king Charles IV of his trip, involving the minister Mariano de Urquijo and the embassador of Sajonia, baron of Forell, are not sufficiently documented due to the scarce data that Humboldt himself offered in his work and to the absence of any other supporting documents. This work studies the preparation of his American trip and its approval by the Spanish court. It incorporates the Memorandum presented —which was «lost» until now—, the autobiography submitted to the authorities and the references given by Philippe de Forrell. Furthermore, it analyses his relationships with the Spanish scientific community in Madrid and the profile of the team that supported him to achieve his targets.

Full Text Available The "Luz del Valle" Savings and Credit Cooperative is a financial institution with five thousand microentrepreneurial partners who have business units. These business units, generally informal, do not have a defined organizational structure or adequate management tools, which influences in the presence of economic problems such as arrears and non-payment of contracted obligations, mainly as a result of a low level of sales. Due to this situation, it is important for cooperatives to support their partners in finding solutions. This is part of the cooperative principles and values of mutual aid, social responsibility and education, training and information for its members, team leaders, managers and employees; these universal principles established by the International Cooperative Alliance (ICA are considered by the savings and credit cooperative "Luz del Valle" as strategies to accompany its partners in the development and growth of their business units. The cooperative organizes a Christmas Fair annually, where 60 microentrepreneurs participate. This event was the opportunity to develop, together with the Metropolitan University of Ecuador, a project that, in its first phase, trained in the formulation of strategies based on the application of the Business Model Canvas; the teaching of this tool, which allows creating, capturing and providing value for clients, was supported by the university community and the program of linkage with society that develops the aforementioned institution; the evaluation of the impact and the economic results are contemplated in a second phase.

Full Text Available Juan Gelman is generally considered by critics to be one of the most important poets of modern Argentina. Born in Buenos Aires in 1930 from Russian-Jewish parents, he published his first collection of poems (Violín y otras cuestiones in 1956. He is a member of the generación del 60, made up of intellectuals influenced in their critical realism by the charisma of Raúl González Tuñón, forerunner of Argentina’s social and political poetry. This group was politically very active, as demonstrated by their experimental language and iconoclastic lyricism. Gelman’s later life was marked by his exile in the wake of the 1976 dictatorship, and by the desaparición of his son Marcelo Ariel, his daughter-in-law Claudia and his grand-daughter Andrea (born in prison. Since then, it was impossible for Juan Gelman to separate his personal plight from Argentina’s historical-political situation, and his poetry became more and more intimate and lyrical, marked by human drama. La junta luz, the author’s only theatre play, was written and published in this second phase.

Schizophrenia is associated with profound cognitive and psychosocial impairments. Glucagon-like peptide-1 receptor agonists (GLP-1RAs) are used for diabetes and obesity treatment, and animal studies have indicated cognitive-enhancing effects. In this investigator-initiated, double-blind, randomized, placebo-controlled trial, we tested non-metabolic effects of exenatide once-weekly (Bydureon™) in obese, antipsychotic-treated patients with schizohrenia spectrum disorder. Before and after 3 months of exenatide (N = 20) or placebo (N = 20) treatment, patients were assessed with the following: Brief Assessment of Cognition in Schizophrenia (BACS), Rey-Osterreith complex figure test (REY), Short-Form Health Survey (SF-36), Personal and Social Performance Scale (PSP) and the Positive and Negative Syndrome Scale (PANSS). We used BACS composite score as the main outcome measure. Repeated measures analysis of variance on BACS composite score showed significant effect of 'Time' (P schizophrenia could reflect a general problem of translating cognitive-enhancing effects of GLP-1RAs from animals to humans or be explained by factors specifically related to schizophrenia spectrum patients with obesity such as antipsychotic treatment. © 2017 John Wiley & Sons A/S.

El objetivo de este estudio es conocer el nivel de respuesta plástica de plántulas de cuatro especies de Quercus a tratamientos de sombra y sequía. Además queremos evaluar qué variables son más plásticas a uno u otro factor, y probar la hipótesis de que los rasgos fisiológicos son más plásticos que los rasgos estructurales. Se cultivaron en condiciones controladas plántulas de Quercus ilex subsp. ballota, Q. súber, Q. pyrenaica y Q. canariensis en tres tratamientos de luz (100, 27 y 3 % de luz incidente y con agua abundante. A partir de mediados de primavera, a la mitad de las plántulas se les suprimió el agua, de forma que recibieron dos tratamientos de agua (riego versus no riego dentro de cada tratamiento de luz. Se analizaron distintos rasgos fisiológicos como la tasa de fotosíntesis y respiración, el punto de compensación y de saturación a la luz, la conductancia estomática, la eficiencia en el uso del agua y de nitrógeno y la eficiencia fotosintética a la luz. También se estudiaron distintos rasgos morfológicos o estructurales, como el área foliar, el área específica foliar, las concentraciones foliares de N y C, y un índice de clorofila. En general, la respuesta plástica de las variables estructurales al factor agua fue muy baja, mientras que la respuesta de las fisiológicas fue relativamente alta. Con la luz, no se detectaron diferencias significativas en la respuesta plástica entre las variables estructurales y fisiológicas. En estas especies de Quercus mediterráneos, la mayor respuesta plástica a la luz podría estar ligada con una estrategia de tolerancia a la sombra, mientras que la baja respuesta plástica al agua (i.e., canalización respondería a una estrategia de tolerancia a la sequía, indicando que la tolerancia a bajos niveles de recursos puede ser

Would John Stuart Mill have regulated pornography?

John Stuart Mill dominates contemporary pornography debates where he is routinely invoked as an authoritative defence against regulation. This article, by contrast, argues that a broader understanding of Mill's ethical liberalism, his utilitarianism, and his feminism casts doubt over such an assumption. New insights into Mill's approach to sex, sexual activity, and the regulation of prostitution reveal an altogether more nuanced and activist approach. We conclude that John Stuart Mill would a...

John started his career and obtained his PhD in a group from Westfield College, initially working on experiments at Rutherford Appleton Laboratory (RAL). From the early 1970s onwards, however, his research was focused on experiments in CERN, with several particularly notable contributions. The Omega spectrometer adopted a system John had originally developed for experiments at RAL using vidicon Cameras (a type of television camera) to record the sparks in the spark chambers. This highly automated system allowed Omega to be used in a similar way to bubble chambers.  He contributed to the success of NA1 and NA7, where he became heavily involved in the electronic trigger systems. In these experiments the Westfield group joined forces with Italian colleagues to measure the form factors of the pion and the kaon, and the lifetime of some of the newly discovered charm particles. Such has been the lasting impact of these measurements that the paper on the pion form-factor had been cited 323 times up to the time of J...

Geology of St. John, U.S. Virgin Islands

Science.gov (United States)

Rankin, Douglas W.

2002-01-01

The rocks of St. John, which is located near the eastern end of the Greater Antilles and near the northeastern corner of the Caribbean plate, consist of Cretaceous basalt, andesite, keratophyre, their volcaniclastic and hypabyssal intrusive equivalents, and minor calcareous rocks and chert. These rocks were intruded by Tertiary mafic dikes and tonalitic plutons. The oldest rocks formed in an extensional oceanic environment characterized by abundant keratophyre and sheeted dikes. Subduction-related volcanism of the east-west-trending marine Greater Antilles volcanic arc began on St. John near the transition between the Early and Late Cretaceous. South-directed compression, probably caused by the initial collision between the Greater Antilles arc of the Caribbean plate and the Bahama platform of the North American plate, deformed the Cretaceous strata into east-west-trending folds with axial-plane cleavage. Late Eocene tonalitic intrusions, part of the Greater Antilles arc magmatism, produced a contact aureole that is as much as two kilometers wide and that partly annealed the axial-plane cleavage. East-west compression, possibly related to the relative eastward transport of the Caribbean plate in response to the beginning of spreading at the Cayman Trough, produced long-wavelength, low-amplitude folds whose axes plunge gently north and warp the earlier folds. A broad north-plunging syncline-anticline pair occupies most of St. John. The last tectonic event affecting St. John is recorded by a series of post-late Eocene sinistral strike-slip faults related to the early stages of spreading at the Cayman Trough spreading center and sinistral strike-slip accommodation near the northern border of the Caribbean plate. Central St. John is occupied by a rhomb horst bounded by two of these sinistral faults. Unlike other parts of the Greater Antilles, evidence for recent tectonic movement has not been observed on St. John.

To generate normative data on the Rey-Osterrieth Complex Figure Test (ROCF) across 11 countries in Latin America, with country-specific adjustments for gender, age, and education, where appropriate. The sample consisted of 3,977 healthy adults who were recruited from Argentina, Bolivia, Chile, Cuba, El Salvador, Guatemala, Honduras, Mexico, Paraguay, Peru, and, Puerto Rico. Each subject was administered the ROCF as part of a larger neuropsychological battery. A standardized five-step statistical procedure was used to generate the norms. The final multiple linear regression models explained 7-34% of the variance in ROCF copy scores and 21-41% of the variance in immediate recall scores. Although t-tests showed significant differences between men and women on ROCF copy and immediate recall scores, none of the countries had an effect size larger than 0.3. As a result, gender-adjusted norms were not generated. The present study is the first to create norms for the ROCF in Latin America. As a result, this study will have important implications for the formation and practice of neuropsychology in this region.

Full Text Available La diferenciación rápida de colonias bacterianas es esencial en muchos campos industriales, científicos y de salud humana y animal. Generalmente esa diferenciación se logra por técnicas microscópicas, bioquímicas o genéticas muy elaboradas que requieren tiempo y entrenamiento. En este estudio se utilizaron técnicas de análisis de imágenes sobre patrones de difracción de luz láser para evaluar su sensibilidad en la diferenciación de colonias bacterianas. Adicionalmente se estudió el efecto del tiempo de crecimiento de las colonias en la generación de estos patrones y se determinó la influencia de la cantidad de medio de cultivo en la difracción de luz láser. Los patrones de difracción del láser se obtuvieron sobre cultivos puros de cinco aislamientos bacterianos B1, B2, B3, B2Ca y B2Cb. En la primera prueba de diferenciación se utilizaron colonias de B2, B3, B2Ca. En el estudio del efecto del tiempo de crecimiento sobre patrones de difracción, las bacterias B1 y B2Cb con uno o dos días de crecimiento. Finalmente, el efecto de la cantidad de medio de cultivo en la difracción de la luz, se evaluó en una prueba en cajas petri con 10, 15 o 20 ml de medio de cultivo estéril sin colonias de bacterias. Mediante un análisis de escalado multidimensional realizado con los parámetros de textura extraídos de las imágenes de los patrones, se obtuvo un agrupamiento adecuado de los patrones asociados a las colonias de cada bacteria evaluada, lo cual indicó que las colonias bacterianas se pueden diferenciar por sus patrones de difracción. Adicionalmente se encontró que no hay variaciones significativas en los patrones de difracción obtenidos de dos aislamientos bacterianos en dos tiempos de crecimiento. El espesor del medio de cultivo afectó la difracción del haz de luz pues patrones obtenidos de cajas petri con 10 ml se separan completamente de los patrones obtenidos con 15 y 20 ml, aunque no hay diferencias entre los dos

A New Reading of Shakespeare's King John.

Science.gov (United States)

Usher, Peter D.

1995-12-01

Shakespeare wrote King John c.1594, six years after the defeat of the Spanish Armada, and ~ 50 years after publication of the Copernican heliocentric hypothesis. It is said to be the most unhistorical of the History Plays, ``anomalous'', ``puzzling'', and ``odd'', and as such it has engendered far more than the customary range of interpretive opinion. I suggest that the play alerts Elizabethans not just to military and political threats, but to a changing cosmic world view, all especially threatening as they arise in Catholic countries. (a) Personification characterizes the play. John personifies the old order, while Arthur and the Dauphin's armies personify the new. I suggest that Shakespeare decenters King John just as Copernicus decentered the world. (b) Hubert menaces Arthur's eyes for a whole scene (4.1), but the need for such cruelty is not explained and is especially odd as Arthur is already under sentence of death (3.3.65-66). This hitherto unexplained anomaly suggests that the old order fears what the new might see. (c) Eleanor's confession is made only to Heaven and to her son the King (1.1.42-43), yet by echoing and word play the Messenger from France later reveals to John that he is privy to it (4.2.119-124). This circumstance has not been questioned heretofore. I suggest that the Messenger is like the wily Hermes (Mercury), chief communicator of the gods and patron of the sciences; by revealing that he moves in the highest circles, he tells John that he speaks with an authority that transcends even that of a king. The message from on high presages more than political change; it warns of a new cosmic and religious world order (d) Most agree that John is a weak king, so Shakespeare must have suspected flaws in the old ways. He would have known that Tycho Brahe's new star of 1572, the comet of 1577, and the 1576 model of his compatriot Thomas Digges, were shattering old ideas. (e) The tensions of the play are not resolved because in 1594 the new order was

Full Text Available Since Extension agents work with a variety of families, there is a desperate need to further our understanding of how to educate diverse communities on a family-related topic. Focused on assisting those teaching marital education to a diverse population, this study attempts to understand how individual differences impact relationship satisfaction and marital communication. Based on John Gottman’s research on marital communication and John Lee’s six loves styles, 653 participants completed a survey to further understanding of the relationship between inter- and intrapersonal variables. Results revealed that marital communication and love styles accounted for 54.6% of the variance in marital satisfaction regardless of difference in demographics. Results of this study provide a resource for educators and practitioners to use with diverse clientele, while also emphasizing the need to understand both intra- and interpersonal variables when working with families.

Con temperaturas constantes la germinación fue mayor con luz entre los 20 y 35 °C para N. longiflora y entre 10 y 20 °C para O. indecora. Con temperaturas alternadas, N. longiflora presentó mayor germinación en un rango amplio rango con luz, y en oscuridad fue mayor sólo con 10-20 °C. O. indecora germinó sólo con luz en un amplio rango de temperaturas alternadas. La temperatura base en luz y en oscuridad fue de aproximadamente 14 °C para N. longiflora y de aproximadamente 6 °C para O. indecora. A partir de la temperatura base se puede inferir que N. longiflora es una especie con un ciclo de crecimiento primavero-estival y O. indecora otoño-primavero-estival.Nicotiana longiflora and Oenothera indecora are species of recent appearance in croplands in the Argentine humid pampa zone and there is a lack of knowledge about the environmental factors affecting their germination. The temperature and light requirements for germination and the base temperature of both species were determined. Under constant temperatures, germination was higher between 20 and 35 °C for N. longiflora and between 10 and 20 °C for O. indecora. Under fluctuating temperatures, N. longiflora showed higher germination rates in a wide range of temperatures with light. In darkness, germination was higher only between 10-20 °C for N. longiflora, whereas O. indecora germinated only with light, within a wide range of fluctuating temperatures. Base temperature under light and darkness conditions was approximately 14 °C for N. longiflora and approximately 6 °C for O. indecora. Base temperature indicates that N. longiflora is a species with a spring

John von Neumann selected letters

CERN Document Server

2005-01-01

John von Neuman was perhaps the most influential mathematician of the twentieth century, especially if his broad influence outside mathematics is included. Not only did he contribute to almost all branches of mathematics and created new fields, but he also changed post-World War II history with his work on the design of computers and with being a sought-after technical advisor to many figures in the U.S. military-political establishment in the 1940s and 1950s. The present volume is the first substantial collection of (previously mainly unpublished) letters written by von Neumann to colleagues, friends, government officials, and others. The letters give us a glimpse of the thinking of John von Neumann about mathematics, physics, computer science, science management, education, consulting, politics, and war. Readers of quite diverse backgrounds will find much of interest in this fascinating first-hand look at one of the towering figures of twentieth century science.

Cuando las huertas de nogal pecanero con densidades de plantación al menos de 100 árboles por hectárea presentan problemas de sombreo, la penetración de luz dentro de la copa del árbol y entre árboles, el crecimiento y la producción son negativamente afectadas. La investigación realizada para estudiar el efecto del aclareo de árboles de nogal pecanero sobre la disponibilidad de la luz y productividad de la huerta es limitada. El objetivo del presente estudio fue determinar el efecto del aclareo de árboles sobre la disponibilidad de radiación fotosintéticamente activa (RFA dentro de árboles permanentes, crecimiento del brote, producción y calidad de la nuez. Este estudio se llevó a cabo en una huerta madura de nogal pecanero con aclareo de árboles de 25 a 50 % durante el periodo 2004-2008. La disponibilidad de RFA dentro de árboles, longitud de brotes y la producción de nuez fueron afectadas por los tratamientos de aclareo; sin embargo, la calidad (porcentaje de almendra por árbol durante el periodo de tres años de estudio no fue significativamente afectada. Los resultados de este estudio indican que un gradual aclareo en huertas con problemas de sombreo debe realizarse para recuperar el crecimiento y componentes de producción.

Foram estudados quatro tempos de envelhecimento acelerado (0, 24, 48 e 72h e a presença ou ausência de luz no teste de germinação. O delineamento experimental adotado foi em blocos casualizados num esquema fatorial 4 x 2, com três repetições. Adotou-se o método de germinação sobre papel em caixa de plástico (Gerbox à temperatura de 25°C. Analisaram-se as variáveis porcentagem de germinação, índice de velocidade de germinação(IVG, tempo médio para germinação (TMG, velocidade média de germinação (VMG e entropia. As avaliações foram realizadas durante 63 dias após a instalação do teste. A ausência de luz favoreceu a germinação e o IVG das sementes de guanxuma. O TMG e a entropiadiminuíram e a VMG aumentou com o aumento do tempo de envelhecimento acelerado e não foram influenciados pela luz. Na presença de luz, a germinação e o IVG foram reduzidos com tempos de envelhecimento acelerado mais longos. Conclui-se que o envelhecimento acelerado de sementes de guanxuma por até 72h proporcionou aumento na qualidade fisiológica das sementes submetidas à germinação no escuro.The objective of this study was to determine the effect ofaccelerated aging and presence of light on the physiological quality of arrowleaf sida (Sida rhombifolia L. seeds.

Full Text Available Es sabido que Alfonso Reyes dejó una enorme impronta intelectual y literaria no sólo en la literatura de su país, Méjico, sino en toda la literatura hispanoamericana. Pero, aparte de las dimensiones de la huella dejada por el autor, lo realmente interesante es el terreno que pisa, y ese, para nosotros, es el terreno ideológico. Así, en el presente artículo ofrecemos una panorámica general sobre la significación cultural del autor mejicano, precisamente para tratar de delimitar que una cosa son las ideologías culturales explícitas y otra cosa es el inconsciente ideológico/literario implícito. En este sentido, se ha efectuado el análisis de dos cuentos del prolífico escritor de Monterrey (La venganza creadora y La cena en relación con otros dos de Edgar Allan Poe y Ernest Hemingway (Allá en Michigan y La casa Usher, respectivamente.

Garrafas de PET para óleo comestível: avaliação da barreira à luz PET bottles for edible oil packaging: evaluation of the light barrier

Directory of Open Access Journals (Sweden)

Leda Coltro

2004-09-01

Full Text Available Os óleos comestíveis são produtos alimentícios sensíveis à luz, pois estão sujeitos à degradação por foto-oxidação, cujas conseqüências são escurecimento do produto e alteração de aroma e sabor, levando à rejeição do produto. Assim, quando os óleos são acondicionados em embalagens transparentes, a foto-oxidação torna-se a principal causa da deterioração oxidativa devido ao efeito da luz, encurtando a vida-de-prateleira do produto e daí surgindo a necessidade da utilização de absorvedores de UV, substâncias incolores que, quando incorporadas ao material da embalagem, absorvem a energia UV incidente ou inativam cromóforos excitados protegendo o produto. Este estudo foi desenvolvido com o objetivo de avaliar a barreira à luz de embalagens de PET disponíveis no mercado brasileiro utilizadas para o acondicionamento de óleo comestível por meio da obtenção de espectros de transmissão de luz especular no UV-Visível. As embalagens que apresentaram barreira à luz foram submetidas a ensaios analíticos com a finalidade de identificação e quantificação do aditivo utilizado. Os aditivos absorvedores de UV identificados nas embalagens plásticas foram relacionados quanto à restrição de uso e limites de composição estabelecidos pela Resolução 105 da Agência Nacional de Vigilância Sanitária - ANVISA. Com isso foi possível fazer um diagnóstico do uso de absorvedores de UV em embalagens de PET utilizadas para o acondicionamento de óleo comestível disponíveis no mercado brasileiro.The edible oils are light sensitive food products since they degrade by photo-oxidation, which promotes darkening of the product, alteration of its flavor and consequently its rejection. For edible oils packed in transparent packages, photo-oxidation becomes the main cause of the oxidative deterioration due to the light effect, reducing the shelf-life of the product. Then, it is necessary to use UV absorbers, colorless substances

The manifesto as genre in Ibsen's John Gabriel Borkman

Directory of Open Access Journals (Sweden)

Christine Korte

2015-02-01

Full Text Available This article examines John Gabriel Borkman’s neo-aristocratic performance of power and authority in Ibsen’s eponymously titled play (1896. After his downfall, John Gabriel has retreated into his once grand reception hall wherein he has become like a petrified relic from a preceding era. His performance within the “fading glory” of the upstairs hall– a veritable theatre for his delusions of grandeur – is one of an outmoded type of bourgeois “hero” whose flagrantly illicit dealings are no longer tenable as capitalism becomes ever-more “rational” and bureaucratic in its façade. The article focuses on John Gabriel’s performance of a “sovereign” or charismatic authority and examines his future visions as “manifestos”. The manifesto is a form belonging to a feudal era of rule by divine right – one that is necessarily “theatrical” in its performance of a legitimate authority. Assuming the voice of the sovereign, John Gabriel attempts to address the needs of the iron-ore miners – a desiring, albeit latent force in Ibsen’s text. The desires of the workers, however, are continually effaced by the bewitching powers of capitalist abstraction, which account for the alienation of family and individuals in Ibsen’s play.   Comparing John Gabriel’s manifesto with Marx and Engels’ Communist Manifesto not only accounts for the end of an age of neo-aristocratic bourgeois decadence, but also marks labour as the definitive socio-political issue of the late 19th century. Where John Gabriel uses a dramaturgy rooted in past models of rule to address the workers in his vision of a benevolent “kingdom”, the Communist Manifesto heralds the death of his class and replaces the voice of the “sovereign authority” with the self-authorising voice of the workers themselves. Borkman’s fatal flaw then is failing to sufficiently address the plight of the iron-ore miners with whom he claims intimate acquaintance but with whom

O Plano Real à luz da experiência mexicana e argentina

Full Text Available O trabalho discute os primeiros dois anos do Plano Real e em especial os seus efeitos sobre as relações externas do Brasil, à luz da experiência de programas de estabilização adotados no México, em 1988-1994, e na Argentina, desde 1991. Embora cada experiência nacional apresente as suas peculiaridades, argumenta-se que a economia brasileira vem revivendo a experiência mexicana e argentina em alguns pontos importantes, combinando sucesso no combate à inflação com acentuada e persistente apreciação cambial, elevados déficits no balanço de pagamentos em conta corrente e dependência de fluxos voláteis de capital internacional.This paper discusses the first two years of Brazil's current stabilization programme - known as the Real Plan - and in particular its effects on the country's external economic relations, in the ligth of similar stabilization programmes adopted in Mexico from 1988 to 1994 and in Argentina since 1991. Although each national experience has its peculiarities, it is shown that the Brazilian economy has been reliving the Mexican and Argentinian experience in some important respects, combining success in terms of inflation reduction, with strong and persistent exchange rate appreciation, high deficits in the balance of payments on current account and dependence on volatile international capital flows.

John Dewey’s Feminist Legacy

Directory of Open Access Journals (Sweden)

Marta Vaamonde Gamo

2016-07-01

Full Text Available This article demonstrates how feminism welcomed and was influenced by the pragmatism of John Dewey. While in real terms his impact on European feminism has been minimal, this was not the case in contemporary America. In this article we study both how Dewey’s ideas were received amongst American feminists, as well as certain aspects of his thinking that could be enormously useful in present-day debates between critical and postmodern feminists. We compare the Deweyan and feminist arguments against the traditional dualisms that acted as philosophical support for social inequality, paying particular attention to mind–body dualism, and the consequent undervaluation of physical and emotional wellbeing. We also show that John Dewey’s proposals were, in fact, more radical than those of the feminists of the day. Indeed, democracy has to be understood as a way of life that affects every dimension of experience, and is crucial to the personal and social growth that enables the unjust social inequalities between men and women to be overcome.

The germanides RE 3 Pt 4 Ge 6 (RE=Y, Pr, Nd, Sm, Gd-Dy) have been synthesized by arc-melting of the elements followed by inductive annealing to improve the crystallinity and allow for structural order. The compounds have been studied by powder X-ray diffraction; additionally the structure of Y 3 Pt 4 Ge 6 has been refined from single-crystal X-ray diffractometer data. It exhibits a (3+1)D modulated structure, indicating isotypism with Ce 3 Pt 4 Ge 6 . The crystal structure can be described as an intergrowth between YIrGe 2 - and CaBe 2 Ge 2 -type slabs along [100]. Temperature-dependent magnetic susceptibility measurements showed Pauli paramagnetism for Y 3 Pt 4 Ge 6 and Curie-Weiss paramagnetism for Pr 3 Pt 4 Ge 6 and Nd 3 Pt 4 Ge 6 . Sm 3 Pt 4 Ge 6 exhibits van Vleck paramagnetism, while antiferromagnetic ordering at T N =8.1(1) K and T N =11.0(1) K is observed for Gd 3 Pt 4 Ge 6 and Tb 3 Pt 4 Ge 6 , respectively.

John Holt Stanway: Gone to Texas

Bryan, J.

2008-01-01

John Holt Stanway (1799Ð1872) was an amateur astronomer who lived in Manchester, England until 1845. He was in contact with the English Ôgrand amateurÕ astronomer, William Henry Smyth, who supported him for Fellowship of the Royal Astronomical Society and evidently advised him on how to build and equip an observatory. Apparently, Stanway had an observatory at Chorlton-cum-Hardy in 1837. In 1845, Stanway left for the United States in response to serious business problems. En route, he met Ashbel Smith, a representative of the government of the Republic of Texas, who convinced Stanway to go to Texas. There he changed his name to John H. Smythe Stanley and settled in Houston, where he re-established his observatory. He became a commercial photographer and wrote about astronomy and other scientific subjects in Houston newspapers until his death in 1872.

2012-12-01

Full Text Available Esta pesquisa foi realizada em um fragmento de floresta estacional semidecídua, localizada em Pirenópolis, Goiás, e investigou as alterações no regime de luz, medida pela densidade de fluxo de fótons, associadas a intervenções silviculturais que visaram, sobretudo, aumentar o crescimento de espécies arbóreas, sem permitir a invasão por espécies oportunistas que poderiam influenciar negativamente a dinâmica da regeneração natural. O delineamento foi em blocos casualizados, em esquema fatorial, testando as diferenças entre tratamentos silviculturais, estações climáticas e alturas de medida no sub-bosque (1,30 m e ao nível do solo. Foram testadas duas intensidades de corte seletivo de indivíduos arbóreos e de cipós na floresta. Os tratamentos foram suficientes para alterar o regime de luz, tanto na estação seca como na estação chuvosa, em acordo com a hipótese testada. O sombreamento na área controle foi de 97% na estação chuvosa e de 86% na estação seca, apresentando diferenças significativas com o sombreamento associado aos tratamentos silviculturais, que variaram de 93% a 94% na chuva e de 77% a 80% na seca. Esse estudo pode auxiliar na validação deste sistema de manejo florestal proposto para as florestas estacionais semidecíduas no Brasil Central, devendo ser associado aos estudos populacionais e de comunidade, preservando os fragmentos florestais encontrados na região e gerando benefícios ambientais e renda extra para a população rural.

Phillips, Kristen; Zaidan, Frederic; Elizondo, Omar R; Lowe, Kristine L

2012-02-02

La Sal del Rey ("the King's Salt") is one of several naturally-occurring salt lakes in Hidalgo County, Texas and is part of the Lower Rio Grande Valley National Wildlife Refuge. The research objective was to isolate and characterize halophilic microorganisms from La Sal del Rey. Water samples were collected from the lake and a small creek that feeds into the lake. Soil samples were collected from land adjacent to the water sample locations. Sample salinity was determined using a refractometer. Samples were diluted and cultured on a synthetic saline medium to grow halophilic bacteria. The density of halophiles was estimated by viable plate counts. A collection of isolates was selected, gram-stained, tested for catalase, and characterized using API 20E® test strips. Isolates were putatively identified by sequencing the 16S rDNA. Carbon source utilization by the microbial community from each sample site was examined using EcoPlate™ assays and the carbon utilization total activity of the community was determined. Results showed that salinity ranged from 4 parts per thousand (ppt) at the lake water source to 420 ppt in water samples taken just along the lake shore. The density of halophilic bacteria in water samples ranged from 1.2 × 102 - 5.2 × 103 colony forming units per ml (cfu ml-1) whereas the density in soil samples ranged from 4.0 × 105 - 2.5 × 106 colony forming units per gram (cfu g-1). In general, as salinity increased the density of the bacterial community decreased. Microbial communities from water and soil samples were able to utilize 12 - 31 carbon substrates. The greatest number of substrates utilized was by water-borne communities compared to soil-based communities, especially at lower salinities. The majority of bacteria isolated were gram-negative, catalase-positive, rods. Biochemical profiles constructed from API 20E® test strips showed that bacterial isolates from low-salinity water samples (4 ppt) showed the greatest phenotypic diversity

2016-09-01

John F. MacDonald was a close friend and mentor whose life was ended far too soon on April 22, 2014. To those who knew him, John was an endearing blend of fiery Scotsman, compassionate socialist, dedicated family man, and tireless investigator. Those close to him valued his loyalty and friendship, relished his biting wit, and puzzled at his self-deprecating manner. His career spanned a remarkable period of discovery from the early identification of excitatory amino acid, to the molecular cloning and characterization of glutamate receptors and the elucidation of mechanisms responsible for regulating their function. A true pioneer in each of these areas, John's research has had a lasting impact on our understanding of excitatory synaptic transmission and its plasticity. Our intent in commemorating John's work is to focus on some notable discoveries that highlight the impact and innovative aspects of John's work. In doing so, we also wish to highlight just how greatly our understanding of the glutamate transmitter systems has advanced since the late 1970s, when John first launched his independent neuroscience career.

Full Text Available El artículo examina la influencia que tuvo el modelo de gobierno de Porfirio Díaz en la construcción de la nación colombiana desde 1884 hasta 1909. La recopilación, análisis e interpretación de fuentes primarias y secundarias, propia del método histórico, se realizó priorizando los libros y la prensa de la época, así como la bibliografía que se considera cardinal para aproximarse al tema. El texto inicia con un recuento de la historia política del período, para luego enfatizar en la figura de Rafael Reyes, un confeso admirador del Porfiriato que fungió como presidente durante el Quinquenio (1904-1909. Tales reflexiones serán el sustrato para cuestionar la historiografía que lo ha reivindicado, equiparando su gestión a la del mandatario mexicano, como el modernizador del país. La conclusión principal del escrito es que, allende las similitudes, la dictadura no fructificó en nuestro medio porque suponía trasgredir tres principios inquebrantables: republicanismo, democracia e institucionalidad.

The influence of John Herschel on the philosophical thoughts of Charles Darwin, both through the former's book, Natural Philosophy, and through their meeting in 1836 at the Cape of Good Hope, is discussed. With Herschel having himself speculated on evolution just a few months before he met Darwin, it is probable that he stimulated at least the beginnings of the latter's lifelong work on the subject.

John Napier life, logarithms, and legacy

Havil, Julian

2014-01-01

John Napier (1550–1617) is celebrated today as the man who invented logarithms—an enormous intellectual achievement that would soon lead to the development of their mechanical equivalent in the slide rule: the two would serve humanity as the principal means of calculation until the mid-1970s. Yet, despite Napier’s pioneering efforts, his life and work have not attracted detailed modern scrutiny. John Napier is the first contemporary biography to take an in-depth look at the multiple facets of Napier’s story: his privileged position as the eighth Laird of Merchiston and the son of influential Scottish landowners; his reputation as a magician who dabbled in alchemy; his interest in agriculture; his involvement with a notorious outlaw; his staunch anti-Catholic beliefs; his interactions with such peers as Henry Briggs, Johannes Kepler, and Tycho Brahe; and, most notably, his estimable mathematical legacy.

One of the Pacific Northwest's most notable outdoor recreation areas, the "John Day Country" in northeastern Oregon, is named after a native Virginian who was a member of the Astor expedition to the mouth of the Columbia River in 1812. There is little factual information about John Day except that he was born in Culpeper County, Virginia, about 1770. It is known also that in 1810 this tall pioneer "with an elastic step as if he trod on springs" joined John Jacob Astor's overland expedition under Wilson Price Hunt to establish a vast fur-gathering network in the Western States based on a major trading post at the mouth of the Columbia River.

High rates of energy expenditure and water flux in free-ranging Point Reyes mountain beavers Aplodontia rufa phaea

We measured water flux and energy expenditure in free-ranging Point Reyes mountain beavers Aplodontia rufa phaea by using the doubly labeled water method. Previous laboratory investigations have suggested weak urinary concentrating ability, high rates of water flux, and low basal metabolic rates in this species. However, free-ranging measurements from hygric mammals are rare, and it is not known how these features interact in the environment. Rates of water flux (210 ?? 32 mL d-1) and field metabolic rates (1,488 ?? 486 kJ d-1) were 159% and 265%, respectively, of values predicted by allometric equations for similar-sized herbivores. Mountain beavers can likely meet their water needs through metabolic water production and preformed water in food and thus remain in water balance without access to free water. Arginine-vasopressin levels were strongly correlated with rates of water flux and plasma urea : creatinine ratios, suggesting an important role for this hormone in regulating urinary water loss in mountain beavers. High field metabolic rates may result from cool burrow temperatures that are well below lower critical temperatures measured in previous laboratory studies and suggest that thermoregulation costs may strongly influence field energetics and water flux in semifossorial mammals. ?? 2007 by The University of Chicago.

The college has implemented a multi-tiered professional renewal and assessment process. These changes of emphasis are the result of significant research and subsequent/associated professional discussion and were supported during the EBA decision-making in 2012. The professional renewal process at John Paul College guides teachers through a cycle of goal setting (related to any aspect of teacher practice which aims to improve student learning and achievement; ongoing discussion between the teacher and a mentor which determines actions; directed classroom observations (3 per term and associated pre and post reflection/discussion; leading to application of changed practice toward achieving the criteria of the goals. The principles of the professional renewal program are to:  enhance development along accepted school-wide, team and department goals;  encourage professional pedagogical reflections and conversations with a colleague/mentor;  motivate improved performance and highlight the next steps in a teacher’s development. Through the introduction of professional renewal, attestation and exemplary teacher processes, the leadership and teachers of John Paul College have achieved an appropriate and innovative balance between self-directed, peer supported/directed and college-wide, strategic initiatives. Each member of the teaching team, from graduate to senior leaders are actively engaged in personalised programs of professional growth which is specifically aimed at improved learning and outcomes of the college’s students.

In this paper we have analysed the Luz Para Todos (Light For Everyone) program in the state of Sao Paulo. We studied the case of ELEKTRO and focused on cost reduction and the economical and financial feasibility of the program. We used the work and experience of the Comissao de Eletrificacao Rural do Estado de Sao Paulo - CERESP (Rural Electric Commission of the Sao Paulo estate) as the basis of this study, which has developed a tool based on the construction plans of companies and cooperatives. This tool aimed to reduce the project costs uses concepts of low cost materials and equipment as well as the concepts of project finance analysis. It considers the funding source, financial statements of the companies and the return of a project. The Light For Everyone project has a social objective to take electricity to rural regions. It fulfils the needs of low income population. The execution of this program requires the participation of a private player which is an electricity distribution company. The economical and financial feasibility of the project is favoured by governmental subsidies. This study shows the dimension of the return obtained by the private player (executing agent). (author)

Is John Locke a democrat?

  Over recent years there has been a tendency to present John Locke as an equalitarian democrat (Ashcraft) and being close to the political views of the levellers (Waldron). This is not a completely new interpretation (Kendall, 1941), but contrasts with the prevalent view presented in textbooks (......, criteria for a democratic process, and the institutions of polyarchy. The conclusion has implications for the relationship between political liberalism and constitutionalism on the one hand and democracy on the other....

Innovación y ruptura en la métrica de la poesía en al-Maqāmāt al-Luzūmiyya de al-Saraqusṭī (s. VI/XII

Directory of Open Access Journals (Sweden)

Ferrando, Ignacio

Full Text Available Al-Maqāmāt al-Luzūmiyya, a collection of 50 picaresque-like stories couched in rhymed prose by Abū l-Ṭāhir al-Saraqusṭī in al-Andalus in the VI/XIIth century, were considered by Western scholars, up until the eighties of XXth century, as highly rhetorical pieces with a negligible and irrelevant content. However, some contemporary scholars argued that they contain some degree of social and political criticism, as they constitute a fictional domain in which subversion and irony play a fundamental role. In this paper, we cast some light on the particular use of metrical patterns in Al-Maqāmāt al-Luzūmiyya, which should be considered another subversion field: a poetical rhythm that avoids the most usual Arabic metrical patterns, contributing to provide the maqāma a flavor of the countergenre.Al-Maqāmāt al-Luzūmiyya, la colección de 50 relatos de corte picaresco escritos en una exigente prosa rimada por Abū l-Ṭāhir al-Saraqusṭī en al-Andalus en el siglo VI/XII, han sido consideradas por los críticos occidentales como piezas de alta retórica y de virtuosismo lingüístico en las que el contenido es prácticamente irrelevante. Sin embargo, a partir de los años 80 del siglo pasado, algunos investigadores han tratado de incidir en el hecho de que esta obra contiene cierto grado de crítica social y política, puesto que constituye un espacio ficticio en el que la subversión y la ironía desempeñan un papel fundamental. En este trabajo vamos a tratar de arrojar luz sobre el uso particular de los esquemas métricos por parte de al-Saraqusṭī, tratando de mostrar que los metros constituyen otro más de los ámbitos de subversión tan caros al autor. De hecho, el uso de ritmos “invertidos” o contrarios a los más habituales de la poesía clásica contribuye a darle a la maqāma ese aire de anti género que la puebla.

contributed significantly to both vertical and horizontal HIV transmission in Barbados. Future studies of HIV incidence and its trend among childbearing women could be important for monitoring the HIV epidemic in this country. Many of the HIV-infected childbearing women in our study were unemployed, sick, and had multiple children. Therefore, to help them to plan for and cope with the disease and also the care of their children beyond the perinatal period, there is a need to provide the women with repeated counseling with continued follow-up and, where necessary, additional economic, social, and medical support.OBJETIVO: Describir el perfil demográfico, las carácterísticas sociales y familiares y los hábitos de vida de las mujeres infectadas por VIH que dan a luz en Barbados, país del Caribe, en comparación con un grupo testigo compuesto de mujeres sin infección por VIH. MÉTODOS: Los datos en que se basa este informe fueron obtenidos del Programa Pediátrico para la Vigilancia del VIH en el Hospital Reina Isabel de Barbados. Los datos abarcaron a todas las mujeres en el país que estaban infectadas por el VIH y que dieron a luz entre 1986 y 2000. Datos similares se obtuvieron de un grupo testigo compuesto de mujeres que dieron a luz pero que no estaban infectadas por el VIH. De las fichas médicas de las mujeres se extrajo la información de tipo general que había sido anotada durante las consultas prenatales.

Full Text Available The Antarctic fish Notothenia coriiceps Richardson, 1844 lives in an environment of daily and annual photic variation and retina cells have to adjust morphologically to environmental luminosity. After seven day dark or seven day light acclimation of two groups of fish, retinas were extracted and processed for light and transmission electron microscopy. In seven day dark adapted, retina pigment epithelium melanin granules were aggregated at the basal region of cells, and macrophages were seen adjacent to the apical microvilli, between the photoreceptors. In seven day light adapted epithelium, melanin granules were inside the apical microvilli of epithelial cells and macrophages were absent. The supranuclear region of cones adapted to seven day light had less electron dense cytoplasm, and an endoplasmic reticulum with broad tubules. The mitochondria in the internal segment of cones adapted to seven day light were larger, and less electron dense. The differences in the morphology of cones and pigment epithelial cells indicate that N. coriiceps has retinal structural adjustments presumably optimizing vision in different light conditions.O peixe Antártico Notothenia coriiceps Richardson, 1844 habita meios com variações fóticas diária e anual e as células da retina se adaptam morfologicamente a esta luminosidade ambiental.

St. John le calviniste, ou l’émule de Gil-Martin Charlotte Brontë’s Calvinist St. John Emulating James Hogg’s Gil-Martin

Directory of Open Access Journals (Sweden)

Jean Berton

2009-07-01

Full Text Available This article aims to show how far Hogg’s archetypal character, Gil-Martin, influenced Charlotte Brontë’s enigmatic character, St. John, who appears in chapters XXVI to XXXV and is mentioned again in the conclusion of Jane Eyre. Some unexpected words, like “glen”, in a greater Yorkshire area, operate as keywords to a “deep context” study in a neo-contextualist approach. Even though St. John cannot be mistaken for a double of Gil-Martin, a fair number of details tend to prove that James Hogg’s Private Memoirs and Confessions of a Justified Sinner deeply influenced Charlotte Brontë—both pride-driven St. John and Gil-Martin stand for demonic despotism. Yet, if Gil-Martin is a straightforward Gothic illustration of Satan, St. John is a reincarnation of a marble-cold Apollo in a dogma-trapped Calvinist. Brontë’s intention was not so much to denounce noxious excesses in religious beliefs as to set her heroine’s wise independence against nefarious male domination: whereas victimised Robert Wringhim is driven to despair and suicide, self-reliant Jane Eyre escapes from St. John’s grip. In both narratives relationships between men and women are shown as tragically warped by religious behavioural extravagance, but only the female character is granted a positive outcome to serve an optimistic view on life: Robert Wringhim is violently wrung out of the society of men and women, St. John Rivers, from “Marsh End”, blindly drifts away to his death in India, and airy Jane, of “Moor House”, wafts away to anchor to Edward Rochester, the sender of the airwave-born call.

How might gay and lesbian literature be read not as a mimetic representation of homosexuality, but as an activity linked to problems of subjectivity and historiography? Reading Dale Peck's novel Martin and John alongside passages from Friedrich Nietzsche's "On the Uses and Disadvantages of History for Life" and Sigmund Freud's "Mourning and Melancholia," this essay argues for an understanding of Peck's text as an attempt to link two apparently different processes of import to contemporary gay male subjects in particular: the writing of what Nietzsche terms "critical history," and the mourning of those lost to HIV disease. It concludes by linking Martin and John to feminist critiques of identity and traditional historiography, as well as noting the connection between these two critiques.

Foram revisados 152 artigos sobre o tema, publicados em revistas acadêmicas brasileiras e internacionais voltadas de forma específica para o ensino de física, entre 1995 e 2015. O diálogo entre os artigos foi estabelecido a partir de dez categorias de classificação dos textos, de acordo com o seu subtema específico: princípios da reflexão, refletância, velocidade da luz, reflexão difusa, imagens reais e virtuais, espelhos planos, espelhos curvos, associações de espelhos, polarização e espelhos relativísticos. A revisão evidenciou grande concentração de esforços de pesquisa em aplicações de espelhos curvos e planos. Por outro lado, temas como refletância, velocidade da luz, espelhos relativísticos e a relação entre os fenômenos da reflexão e da polarização mostraram carência de trabalhos. A revisão mostrou que esses quatro subtemas não são usuais nas publicações de autores brasileiros, demonstrando possibilidades de pesquisas futuras. O uso de materiais cotidianos em atividades experimentais também foi evidenciado, principalmente em artigos voltados para o tratamento da óptica no ensino médio, fato que contribui para a continuidade de pesquisas sobre o tema. Ressalta-se ainda que a celebração do Ano Internacional da Luz (2015 não parece ter alavancado de forma substancial as publicações sobre o tema.

Our 10-year experience with PUVA treatment for alopecia areata, partialis, totalis and universalis was retrospectively reviewed using charts and follow-up questionnaires for 70 patients at St John`s Institute of Dermatology. In all cases, several previous therapies were judged to be unsatisfactory prior to starting PUVA, and many cases were already deemed clinically refractory prior to referral for PUVA. If cases of vellus hair growth are excluded, and those who lost their PUVA-induced regrowth rapidly on follow-up, the effective success rate was at best 6.3% for alopecia areata partialis, 12.5% for alopecia areata totalis and 13.3% for alopecia areata universalis. We affirm that PUVA is generally not an effective treatment for alopecia areata. (Author).

Please see the PDF for the transcript of the lecture. General remarks by Angelo Bassi and GianCarlo Ghirardi During the autumn of 1989 the International Centre for Theoretical Physics, Trieste, celebrated the 25th anniversary of its creation. Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5-10 September 2005, it occurred to us that this lecture, which has never been published, might represent

Among the many prestigious speakers, who delivered extremely interesting lectures on that occasion, was the late John Stewart Bell. All lectures have been recorded on tape. We succeeded in getting a copy of John's lecture. In the lecture, many of the arguments that John had lucidly stressed in his writings appear once more, but there are also extremely interesting new remarks which, to our knowledge, have not been presented elsewhere. In particular he decided, as pointed out by the very choice of the title of his lecture, to call attention to the fact that the theory presents two types of difficulties, which Dirac classified as first and second class. The former are those connected with the so-called macro-objectification problem, the latter with the divergences characterizing relativistic quantum field theories. Bell describes the precise position of Dirac on these problems and he stresses appropriately how, contrary to Dirac's hopes, the steps which have led to a partial overcoming of the second class difficulties have not helped in any way whatsoever to overcome those of the first class. He then proceeds to analyse the origin and development of the Dynamical Reduction Program and draws attention to the problems that still affect it, in particular that of a consistent relativistic generalization. When the two meetings Are there quantum jumps? and On the present status of Quantum Mechanics were organized in Trieste and Losinj (Croatia), on 5-10 September 2005, it occurred to us that this lecture, which has never been published, might represent an

Full Text Available O artigo apresenta a discussão da compreensão da terceirização do trabalho docente no ensino superior privado, realizado por meio de cooperativas de mão de obra, à luz da responsabilidade social da educação superior. Conceitualiza a responsabilidade social, privilegiando duas abordagens: a normativa, de ordem legal, e a ética, direcionada ao desenvolvimento humano. Examina a coerência ética que deve existir na gestão universitária no equacionamento das exigências de maximização de recursos visando a ganhos de competitividade, com os princípios e valores que deveriam nortear os empreendimentos educacionais dentro de um cenário marcado pelas exigências e demandas do Estado e da sociedade por uma maior responsabilidade social da educação superior, principalmente do setor privado.

Full Text Available Un disegno di John Hejduk è l'occasione per riflettere sul rapporto tra ideazione, rappresentazione e realizzazione dell'opera di architettura, seguendo i ragionamenti del maestro americano. Attraverso i mezzi che le sono propri, walls, roofs, boundaries, l'immagine architettonica ha la capacità di evocare e richiamare il senso profondo di situazioni inattese, “rinfrescare” la nostra visione delle cose contro il pericolo dell'automatizzazione. Ne esce un quadro in cui, nel circolo creativo che coinvolge artefice e fruitore, la realtà dell'architettura contribuisce per la sua parte al progetto di “fabbricazione del mondo”. / A drawing by John Hejduk is an opportunity to reflect on the relationship between the creation, representation and realisation of a work of architecture, following the reasoning of the American maestro. Through its own means - walls, roofs, boundaries - the architectural image has the capacity to evoke and invoke the profound sense of unexpected situations, to "refresh" our vision of things against the danger of automation. What emerges is a scenario in which, in the creative circle involving maker and spectator, the reality of architecture contributes to its part in the project of "manufacturing the world"

John Greenleaf's life of science.

This article summarizes the life and career of John E. Greenleaf, PhD. It complements an interview of Dr. Greenleaf sponsored by the American Physiological Society Living History Project found on the American Physiological Society website. Dr. Greenleaf is a "thought leader" and internationally renowned physiologist, with extensive contributions in human systems-level environmental physiology. He avoided self-aggrandizement and believed that deeds rather than words define one's legacy. Viewed another way, however, Greenleaf's words define his deeds: 48% of his 185 articles are first author works, which is an unusually high proportion for a scientist of his stature. He found that writing a thorough and thoughtful discussion section often led to novel ideas that drove future research. Beyond Greenleaf's words are the many students, postdocs, and collaborators lucky enough to have worked with him and thus learn and carry on his ways of science. His core principles included the following: avoid research "fads," embrace diversity, be the first subject in your own research, adhere to rules of fiscal responsibility, and respect administrative forces-but never back down from them when you know you are right. Greenleaf's integrity ensured he was usually right. He thrived on the axiom of many successful scientists: avoid falling in love with hypotheses, so that when unexpected findings appear, they arouse curiosity instead of fear. Dr. Greenleaf's legacy will include the John and Carol Greenleaf Award for prolific environmental and exercise-related publication in the Journal of Applied Physiology.

2010-01-01

Mycobacterium avium subsp. paratuberculosis (MAP) is the etiological agent of Johne disease, a granulomatous enteritis of cattle and other domesticated and wild ruminant species. Johne disease is prevalent worldwide and has a significant impact on the global agricultural economy. Current vaccines against Johne are insufficient in stemming its spread, and associated side-effects prevent their widespread use in control programs. Effective and safe vaccine strategies are needed. The main purpose of this paper is to propose and evaluate the development of a novel oral subunit-vaccine using a patho-biotechnological approach. This novel strategy, which harnesses patho-genetic elements from the intracellular pathogen Listeria monocytogenes, may provide a realistic route towards developing an effective next generation subunit vaccine against Johne disease and paratuberculosis.

Cognitive models of drawing are mainly based on assessment of copying performance of adults, whereas only a few studies have verified these models in young children. Moreover, developmental investigations have only rarely performed a systematic examination of the contribution of perceptual and representational visuo-spatial processes to copying and drawing from memory. In this study we investigated the role of visual perception and mental representation in both copying and drawing from memory skills in a sample of 227 typically developing children (53% females) aged 7-10 years. Participants underwent a neuropsychological assessment and the Rey-Osterrieth Complex Figure (ROCF). The fit and invariance of the predictive model considering visuo-spatial abilities, working memory, and executive functions were tested by means of hierarchical regressions and path analysis. Results showed that, in a gender invariant way, visual perception abilities and spatial mental representation had a direct effect on copying performance, whereas copying performance was the only specific predictor for drawing from memory. These effects were independent from age and socioeconomic status, and showed that cognitive models of drawing built up for adults could be considered for predicting copying and drawing from memory in children.

Process and progress: John Hughlings Jackson's philosophy of science.

Science.gov (United States)

Jacyna, L Stephen

2011-10-01

Some scepticism has been voiced over whether the work of John Hughlings Jackson possesses any significant philosophical orientation. This article argues that Hughlings Jackson was acquainted with the work of a wide range of philosophers. In particular, certain aspects of the writings of John Stuart Mill are reflected in Hughlings Jackson's own work. From early in his career, Hughlings Jackson adopted a critical stance in his neurological papers, seeking to expose shortcomings in the conventional practices of his peers and urging greater methodological rigour and sophistication in order to advance their science. This critical and 'procedurist' bias endows Hughlings Jackson's writings with a characteristically modern character.

The 'Luz do Campo' program has created positive and favorable impact to the opening of opportunities in the rural area. It has contributed to facilitate the access of workers to energetic facilities and has contributed to providing them with better social and economical conditions. As a consequence after the accomplishment of the rural electrification process in the settlements of 'Anhumas' and 'Maria Neto' implanted in Ribeirao Claro in Parana, it was possible to come to terms with two projects of Sericiculture in that location. The energy consumption of these projects has not been only restricted to human comfort, but has also been aimed at the production. As a result, the economical success achieved in those settlements in less than a year's time, is due to the transformation actions in the countryside that have lowered poverty and raised the perspectives of better life quality to the settlers.

La responsabilidad en el derecho penal internacional: una aproximación desde la filosofía de John Searle. Reflexiones a partir del caso Lubanga

Directory of Open Access Journals (Sweden)

Rodrigo A. González Fernández

2013-06-01

Full Text Available En este trabajo examinamos el tópico de la responsabilidad en el derecho penal internacional a la luz de la filosofía de John Searle, y del fallo dictado por la Corte Penal Internacional en el caso de Thomas Lubanga. En el primer acápite analizamos la declaración de responsabilidad penal en función de la teoría de actos de habla de Austin y de Searle, tratándola como un acto ilocucionario cuyo significado es dependiente de un marco institucional específico. Luego, en el segundo acápite, mostramos de qué forma tal marco puede reconstruirse como un ejemplo paradigmático de la realidad social construida descrita por Searle, especialmente en virtud del nexo entre mente, lenguaje y sociedad. A nuestro juicio, los conceptos de intencionalidad colectiva, atribución de funciones de estatus y poderes deónticos son fundamentales para entender tal nexo. En efecto, tal como argumentamos en la tercera sección, los sistemas de poderes deónticos asociados al derecho internacional no solo explican la aparición de Tribunales penales internacionales, como la Corte Penal Internacional, sino además el carácter imprescriptible de los crímenes de lesa humanidad. Los acuerdos internacionales que promueven y protegen los derechos humanos, y que tratan la imprescriptibilidad de aquellos crímenes, son objeto de análisis en la sección final, en donde exponemos algunas reflexiones finales a partir del caso Lubanga.

Filsafat multikulturalisme John Rawls merupakan alternatif tawaran politik kebudayaan untuk mengatasi konflik horizontal. Menurut Rawls, suatu masyarakat yang adil bukanlah hanya menjamin “the greatest happiness for the greatest number” yang selama ini terkenal dalam prinsip demokrasi.

MPI Enhancements in John the Ripper

John the Ripper (JtR) is an open source software package commonly used by system administrators to enforce password policy. JtR is designed to attack (i.e., crack) passwords encrypted in a wide variety of commonly used formats. While parallel implementations of JtR exist, there are several limitations to them. This research reports on two distinct algorithms that enhance this password cracking tool using the Message Passing Interface. The first algorithm is a novel approach that uses numerous processors to crack one password by using an innovative approach to workload distribution. In this algorithm the candidate password is distributed to all participating processors and the word list is divided based on probability so that each processor has the same likelihood of cracking the password while eliminating overlapping operations. The second algorithm developed in this research involves dividing the passwords within a password file equally amongst available processors while ensuring load-balanced and fault-tolerant behavior. This paper describes John the Ripper, the design of these two algorithms and preliminary results. Given the same amount of time, the original JtR can crack 29 passwords, whereas our algorithms 1 and 2 can crack an additional 35 and 45 passwords respectively.

Electromagnetic noise spectrum at John TS [transmission station

International Nuclear Information System (INIS)

Hatanaka, G.K.

1992-01-01

Canadian National (CN) is proposing the development of a commercial office tower on a site directly south of John Transmission Station (TS). CN is concerned about the potential effects of fields originating from John TS and other nearby sources on the operation of sensitive equipment and occupants of the building. Potential equipment and tenants might include data processing equipment and television and radio broadcasting companies. A study was conducted to characterize the severity of the electromagnetic environment at the site in order to address these concerns. Measurements of the electromagnetic spectrum from 100 kHz to 300 MHz were performed from a mobile test facility that features a 5 kW diesel generator and an extendible antenna mast. Peak measurements were made using a selectable measurement time of 0.05 s. It was found that the highest noise levels result from micro-gap discharges under dry weather conditions. The micro-gap discharges are characteristic of defect noise sources associated with substation hardware. At 0.5 MHz the noise levels are typical of median noise levels expected for the International Radio Consultive Committee (CCIR) defined business environment. At 74 MHz the noise levels are more severe than the expected levels for this type of environment. However, levels more representative of the business environment will be achieved by eliminating the micro-gap noise sources attributed to John TS. 6 refs., 11 figs., 2 tabs

The CRISPR-Cas (clustered regularly interspaced short palindromic repeats and associated proteins) is one of the important known immune mechanisms in archaea and bacteria. This adaptive immune system degrades invading genetic elements and protects the cell. Amongst 3 main types I, II and III...... of CRISPR system, two types (I and III) are found in archaea. However, in Sulfolobus species, subtypes IA, I-D, and III-B, III-D and rarely III-A are found.

Fossil Flora of the John Day Basin, Oregon

Knowlton, Frank Hall

1902-01-01

For a number of years I have been gradually accumulating material for a thorough revision of the Tertiary floras of the Pacific slope. Fossil plants are known to occur at numerous points within this area, and their study and identification has already furnished valuable data bearing on the geological history of the region, and when still further exploited it is confidently expected that they will afford more exact data for the use of geologists. This investigation is progressing satisfactorily, and at no distant day it is hoped to have it in form for final publication. From time to time various members of the United States Geological Survey, as well as others not connected with this organization, have sent in small collections of fossil plants for determination. These have been studied and reported upon as fully as the condition of the problem permitted, so that the determinations could be immediately available to geologists, but with the reservation that none of the questions could be fully settled until all known material had been studied and properly correlated. The rich fossil plant deposits in the John Day Basin, as set forth more fully in the historical account which follows, have been known for a period of nearly fifty years, but their study has been carried on in a more or less desultory manner. There has also been considerable confusion as to the horizons whence these plants came. As various species of plants described originally from the John Day region were detected in various other localities in Oregon, and in surrounding areas, as central Washington, western Idaho, and northern California, it became more than ever apparent that a thorough study of all material obtainable from this type area would be necessary before any definite or satisfactory conclusions could be reached. The immediate incentive for this revision was furnished by the receipt of a considerable collection of plants, made by Dr. John C. Merriam in 1900 while he was in charge of an

In his novel The Infinities, in Italian Teoria degli Infiniti, John Banville takes cue from Kleist’s Amphytrion to devise a novel where classicality interweaves with science and science fiction through the invention of a world where the ancient gods intermingle with the humans while waiting for the death of Adam Godley, a famous mathematician who explained how an infinity of worlds exist and interact with each other. To translate this book I had not only to work extensively on lexis and style, but also to do considerable research to render the many literary and non literary references. Some examples of these struggles with the source text during the translation process are given in the present paper. Riassunto - John Banville, autore irlandese noto per la sua prosa raffinata, scrive in una lingua che rappresenta una sfida continua e affascinante per chi lo traduce. La sua complessità stilistica, che sfrutta molteplici registri linguistici e si avvale di scelte lessicali cui spesso è arduo trovare un traducente italiano soddisfacente, costringe il traduttore a fare ricorso a tutte le sottigliezze del proprio mestiere per restituire quanto più possibile l’eleganza dell’originale nella propria lingua. Nel romanzo The Infinities, tradotto in italiano come Teoria degli infiniti (Guanda, Parma 2011, Banville prende spunto dall’Anfitrione di Kleist per costruire un romanzo che guarda alla classicità sconfinando in un misto di scienza e fantascienza con la concezione di un’infinità di mondi paralleli teorizzata dal matematico Adam Godley, il protagonista morente al cui capezzale si radunano uomini e antichi dei in attesa che il cerchio della vita e della morte si compia

Full Text Available Enquanto compreende avanços científicos, o homem busca compreender a si mesmo. Partindo da citação de Carl Sagan, vemos que a Arte é um dos caminhos para a humanização, e os vínculos entre ciência (tecnologia e arte são cada vez mais estreitos. Um dos artistas que melhor trabalham dentro do nicho conhecido como “arte tecnológica” é Eduardo Kac. Sua trajetória inicial é apresentada aqui, dos “holopoemas” à “arte da telepresença”. Vemos o artista-teórico completo, profundo conhecedor da história da arte eletrônica. O livro Luz & letra: ensaios de arte, literatura e comunicação, sua obra de referência, é apresentado em essência, situando-se sua importância. É uma das poucas obras no Brasil a discutir, pela ótica de quem fez parte, eventos ligados ao advento da arte tecnológica nos anos 1980.In our quest to understand scientific advances, we seek to understand ourselves. Employing Carl Sagan's insight as a departure point, we see that art is one of the paths for humanization and that the links between science (technology and art are increasingly narrow. One of the artists who best works within the realm known as “art and technology” is Eduardo Kac. This essay explores Kac's early artworks, starting with “holopoems” and arriving at “telepresence art”, and especially his texts. We see a complete artist-theorist, with an unrivaled knowledge of electronic art and literature, in part because his theorizing emerges from having actively participated in the creation of the events he refers to. Of special interest is Kac's book Light & letter: essays in art, literature, and communication, which collects his writings of the 1980s. This is a fundamental work and mandatory reference for the study of the experimental art and literature of the period.

Full Text Available El explosivo crecimiento del stock edificado de los últimos años en las ciudades chilenas se ha visto reflejado en concentraciones inmobiliarias de gran altura, que irrumpen estrepitosamente en la morfología de las ciudades chilenas. Externalidades son observadas en los espacios y edificios vecinos tales como extensas áreas de sombreamiento que afectan las condiciones térmicas y lumínicas. Estas construcciones se realizan aparentemente acordes a la norma urbanística, pero afectan la luz solar incidente en fachadas y suelos, disminuyendo las posibilidades de captación y su uso como energía renovable. El objetivo del presente artículo es explorar mediante modelos espaciales –energéticos, distintas formas de ocupación de suelo, cambiando la altura edificada, pero manteniendo la constructibilidad en cinco ciudades chilenas. Las ciudades seleccionadas se sitúan en el centro sur de Chile, emplazadas tanto en el borde costero como el valle central y han presentado crecimientos inmobiliarios importantes en los últimos años. Los resultados muestran valores de energía más elevados en configuraciones de mayor altura, y menores valores relativos a medida que asciende latitudinalmente. El modelo básico ha sido una manzana de 1 ha como punto de partida, por tanto los resultados no son aplicables a un tejido urbano que es más complejo.

Full Text Available This study aims to understand the concept of human and Ibn Khaldun's ideas of education; to understand the concept of human and educational thought of John Dewey; to know the similarities and differences between the ideas of Ibn Khaldun and John Dewey on the concept of human and education. Various problems have been addressed through the library research method. The study produced several findings: First, human beings according to Ibn Khaldun as a creation of God with all the potential fitted to the five senses and intellect become intellect. The purpose of education opens the mind and maturity of the individual to the advancement of religious, industrial and social system. Material teaching is as educational planning. The method is to advocate phasing method, repetition, widya-tours and training (practice. Secondly, according to John Dewey man is a subject that has the ability, strength, personality, and existence who are capable of changing realities. The goal of education is only to gain happiness in the world life. The method of education is including problem solving, learning by doing and discipline. Third, the thought of Ibn Khaldun is much more religious because it is influenced by its control logic in religious knowledge, so that emphazises more on human spirituality in building civilization. While John Dewey is more radical and extreme, He proposed progressive education which strives against traditional teaching authority. Both Ibn Khaldūn dan Dewey are arise from inhuman socio-cultural environment and recognize the existence of human existence with nature and humanity impulse.

Este trabajo se enfocó en analizar los efectos del método de alimentación eléctrica de las bombillas sobre la estabilidad de la luz emitida, la relación entre los cambios de tensión y la intensidad lumínica lograda, y las implicaciones que la potencia disipada pueda tener sobre la distribución espectral obtenida. Se encontró, principalmente, que el uso de tensión variable incide de manera negativa en la estabilidad de la emisión lumínica y, además, que la temperatura de operación del filamento juega un rol de suma importancia en el calentamiento que pueda experimentar el panel, así como en la proporción de energía emitida que el dispositivo fotovoltaico es capaz de aprovechar.

Weber, Harald W.

2014-04-01

The local Organizing Committee and the International Advisory Committee of EUCAS 2013 decided to dedicate the Session 'Pinning and Flux Dynamics I' to the memory of Professor John Clem, who passed away on 2 August 2013. Let me briefly summarize John's career and try to convey the incredible loss for the whole superconductor community. John was born in 1938 in Waukegan, a small town in Illinois. After school he obtained several scholarships at the University of Illinois. There he received a BSc in Engineering Physics in 1960, followed by an MSc in Physics in 1962, and earned a PhD focusing on the theory of superconductivity under John Bardeen in 1965. After two years of postdoctoral positions at the University of Maryland and the Technical University of Munich, he joined the Physics Department of the Iowa State University and the Ames Laboratory in 1967, where he spent the rest of his scientific career. He became Full Professor at ISU and Senior Physicist at the Ames Lab in 1975 and was Chairman of the Physics Department from 1982 to 1985. He spent several sabbaticals in the US at IBM Yorktown Heights, Stanford and EPRI in Palo Alto, was named 'Distinguished Professor' at ISU, was a Fellow of the American Physical Society and the Institute of Physics in London and, at the ASC 2012 in Portland he received the IEEE Award for 'Continuing and Significant Contributions in the Field of Applied Superconductivity', especially for his theoretical insight into the nature of vortices in 2D superconductors, which he called 'pancake vortices'. John, who married his high school sweetheart Judy right after college graduation, immediately turned Ames into a much-visited center for scientists from all over the world (including myself), who were interested in vortex physics and the properties of the flux line lattice, flux pinning, flux cutting and vortex dynamics. But it was not only the science at ISU that attracted us, it was also the warm atmosphere created by John and Judy at

Full Text Available As antocianinas são corantes naturais que podem ser utilizadas como alternativa em substituição aos corantes sintéticos. Entretanto, a baixa estabilidade destes compostos é o principal fator que dificulta sua aplicação como corante em alimentos. Frente à escassez de estudo sobre o pigmentos antociânicos da pitanga roxa, este trabalho teve como propósito avaliar a sua estabilidade à luz e ao congelamento. Utilizando a leitura de absorbância do extrato antociânico submetido às condições experimentais foi evidenciado que a luz reduziu o seu tempo de meia-vida, enquanto que a temperatura de congelamento exerceu pequeno efeito na degradação dos pigmentos.Anthocyanins are natural colorants that can be used as alternative to synthetic dyes. However, the low stability of these compounds is the main drawback in their application as food colorants. Since the information on anthocyanin pigments in Surinam cherry is scarce, the purpose of this investigation was to assess their stability to light and freezing storage. The anthocyanin extract absorbance, under the experimental conditions, showed that light incidence reduced the half-life of anthocyanin extract; meanwhile the freezing storage had little effect on these pigments degradation.

Full Text Available John Rawls, American contemporary philosopher, has chosen the title of constructivism for his views on philosophy of ethics and politics. The base of his veiws is the same as the theory of social contract which has been discussed before by John Locke and Imanuel Kant. Rawls completes this view by the condition of impartiality and fairness , which is distinguished by ignorance about the position of self (the veil of ignorance in primary situation. Rawls criticises intutionism and utilitarianism and holds an antirealistic approach towards ethics . The theory that has been delivered by Allame Tabatabee (the constructional perception caused agreements and disagreements, but his idea seems to be new and effective in Islamic philosophy. Based on this idea many conceptions are constructive including goodness , badness and justice. The aim of this paper is to analyse and give a comparison between these ideas and studies similarities and differences with regard to topics such as antirealism, objectivity, criteria of justification and separation of science and ethics.

Elaheh Moradi

2017-01-01

Full Text Available Rey's Auditory Verbal Learning Test (RAVLT is a powerful neuropsychological tool for testing episodic memory, which is widely used for the cognitive assessment in dementia and pre-dementia conditions. Several studies have shown that an impairment in RAVLT scores reflect well the underlying pathology caused by Alzheimer's disease (AD, thus making RAVLT an effective early marker to detect AD in persons with memory complaints. We investigated the association between RAVLT scores (RAVLT Immediate and RAVLT Percent Forgetting and the structural brain atrophy caused by AD. The aim was to comprehensively study to what extent the RAVLT scores are predictable based on structural magnetic resonance imaging (MRI data using machine learning approaches as well as to find the most important brain regions for the estimation of RAVLT scores. For this, we built a predictive model to estimate RAVLT scores from gray matter density via elastic net penalized linear regression model. The proposed approach provided highly significant cross-validated correlation between the estimated and observed RAVLT Immediate (R = 0.50 and RAVLT Percent Forgetting (R = 0.43 in a dataset consisting of 806 AD, mild cognitive impairment (MCI or healthy subjects. In addition, the selected machine learning method provided more accurate estimates of RAVLT scores than the relevance vector regression used earlier for the estimation of RAVLT based on MRI data. The top predictors were medial temporal lobe structures and amygdala for the estimation of RAVLT Immediate and angular gyrus, hippocampus and amygdala for the estimation of RAVLT Percent Forgetting. Further, the conversion of MCI subjects to AD in 3-years could be predicted based on either observed or estimated RAVLT scores with an accuracy comparable to MRI-based biomarkers.

Full Text Available Foi estudado o efeito de níveis de luz e de nitrogênio na atividade da enzima redutase de nitrato e nos teores de nitrato e de açúcares nas folhas de plantas jovens de café (Coffea arabica L, assim como as possíveis relações entre a disponibilidade desses compostos e a atividade enzimática. Foram utilizadas plantas de dez meses de idade cultivadas em vasos contendo uma mistura de terra mais composto, e mantidas em condições ambientais em pleno sol e em 50% da luz solar. Metade das plantas de cada tratamento de luz foi suplementada semanalmente com nitrogênio. Os resultados mostraram que a atividade da redutase de nitrato, nos dois tratamentos de luz, foi maior nas plantas suplementadas com nitrogênio. Para um mesmo nível de nitrogênio, as plantas cultivadas em pleno sol apresentaram menor atividade da redutase de nitrato, maiores teores de nitrato e de açúcares e maiores taxas de transpiração, do que as cultivadas na sombra. Tais resultados indicam que a menor atividade da redutase de nitrato nas plantas cultivadas em pleno sol aparentemente não foi devida a limitações na disponibilidade de nitrato e de açúcares para fornecer a energia necessária para a redução de nitrato.The effect of levels of light and nitrogen on the activity of the enzyme nitrate reductase and its relationship with the availability of sugars and nitrate was studied in leaves of coffee plants (Coffea arabica L. cv. Catual. Ten month old plants were grown on pots containing a mixture of soil and compost, and were kept at full or 50% sunlight. Half of the plants of each light treatment received nitrogen supply. The results showed that the activity of nitrate reductase was higher on plants supplied with nitrogen at both light treatments. For the same nitrogen level, plants grown under full sunlight presented lower nitrate reductase activity, higher nitrate and sugars concentrations, and higher transpiration rates than plants kept at 50% sunlight

John Birmingham (1814-1884) of Millbrook, County Galway, was an outstanding amateur astronomer, now completely forgotten. He discovered the 1866 nova, T Coronae Borealis. Later his name was assigned to a feature near Anaxagoras on the Moon. In 1884 the Royal Irish Academy awarded him its Cunningham Gold Medal for his catalogue of the red variable stars. John Birmingham was not only an acute observer, he also wrote numerous semi-popular articles on many aspects of astronomy. He was also active in geology and railway surveying.

Full Text Available The analysis of the ornamental masorah of folio 158a of Manuscript M1 allows the author to correct and improve the description made by Ch. D. Ginsburg in his introduction to the Bible. The author indeed agrees on the identification of the text as a masoretic appendix to the books of Kings. However, the beginning and the contents of the manuscript must be revised. Ginsburg describes only one of the four lists of the appendix, namely the one dealing with the differences between Eastern and Western recensions; the other three lists are the following: sedarim, peseqim, and words vocalized with patah, which are exceptional because they are pausal forms.

El estudio detallado de la masora ornamental del folio 158a del manuscrito M1 me ha permitido corregir y puntualizar la descripción que hace de este folio Ch. D. Ginsburg en la Introducción a su Biblia. Por una parte, estamos de acuerdo en que se trata de un apéndice masorético a los libros de Reyes, pero no lo estamos en lo que se refiere al sitio donde comienza, ni al contenido total del mismo. Ginsburg sólo describe una lista de las cuatro que contiene, la de las diferencias entre los textos orientales y occidentales; las otras tres son: sedarîm, paseqîm y palabras vocalizadas con patah, que constituyen una excepción por estar en pausa.
