    Orientalism and Occidentalism are interrelated concepts. Orientalism is defined in three keys ways: (i) as a study of “the Orient”; (ii) as a cultural and aesthetic concern with “the Orient”; and (iii) as a critical approach to understanding the construction of “the Orient” by European and American

Más allá de las implicaciones en materia de violencia o, eventualmente, de estrategia militar, es evidente que las respuestas que se den a estos interrogantes tienen múltiples consecuencias sobre la estabilidad social, la seguridad, las migraciones, las libertades, las concepciones de vida y sobre todo, sobre las formas de convivencia social. Entonces tenemos que detenernos para saber quiénes somos ante nosotros mismos y los demás. En este artículo se presenta una posible respuesta a estos interrogantes.

    International Nuclear Information System (INIS)

    1999-01-01

    Financial information from Canadian Occidental Petroleum Ltd. and a review of their 1998 operations was made available for the benefit of shareholders. The company's core oil and gas business activities include exploration, development, production and marketing of crude oil and natural gas. The company produces oil and gas in Canada, Yemen, the Gulf of Mexico and Nigeria. Canadian Occidental also owns a 7.23 per cent share in the Syncrude joint venture. The company is developing new production in Hay, British Columbia, offshore west Africa and offshore northwest Australia. They are also one of North America's top three manufacturers of sodium chlorate. The report presents a summary of operations, a thorough management discussion and analysis of results and provides the customary consolidated financial statements and notes. Overall, 1998 was described as a difficult year financially, due to falling commodity prices. On the operations side, the company experienced its best results to date, producing more oil and gas than ever before. The company also invested over $ 950 million in new projects and opportunities. Some of the Company's most promising projects are located offshore Nigeria, offshore northwest Australia, in the Gulf of Mexico and in western Canada. These projects are expected to add 40,000 BOE of production by early 2000, with promise of attractive returns even at current low oil prices. tabs., figs

  8. Two Views of Liberty, Occidental and Oriental(?

    Bruno Leoni

    2009-02-01

    Full Text Available This paper, by the late Bruno Leoni, was originally presented at a special meeting of the Mont Pèlerin Society (Tokyo, Sept. 5–10, 1966, and was originally published in the Italian journal Il Politico in 1966. The paper displays Leoni’s fondness for Chinese culture, and is essentially a defense of the unity of mankind. Westerners are often of the belief that the Occidental, or Western, individual freedom-based view of liberty is distinct from the Oriental (Eastern view of liberty. Leoni challenges this perspective. Mill believed that disregard for custom was what made the West both free and different from the rest of the world, while the Oriental approach is more backward and based on blind respect for customs. However, custom has often been invoked both in the East and in the West to oppose and limit the power of tyrants, and to defend or to secure civil or political liberty. Mill argued that disregard of custom accounts for novelty, novelty for diversity of character and culture, and the latter for freedom and progress, but there was an unsurpassed diversity of character and culture when Oriental and Occidental people were put together under the rule of the Roman emperors. Furthermore, the “Orient” was not monotonous, dull, and homogeneous, as Mill presumed; to the contrary, Europe cannot show in any period of its history a variety of races, languages, cultures, philosophies and religions even slightly comparable to those of India or China. In fact, Buddha and Confucius were both concerned mainly with individual freedom. Confucius’s theory of society, in particular, was very individualistic; he clearly formulated for the first time in recorded history that principle of “reciprocity,” the “golden rule” for any liberal society. He maintained that the very fundamental principle for a happy society is “Not doing to others what one does not wish them do to one’s self.” Confucius shared, along with the greatest masters of

    Full Text Available Modernity changed the community interests; it idealized individuality and liberal democracy, and based its main aim on pushing religion to the outskirts of human life. Western Christianity adjusted to modernity to justify the developments while Islam accepted it only to the extent of its capacity to authenticate the realities stated by the Qur’an. Orientalism, Occidentalism, and Islamism play impressive role in a variety of contexts today. Occidentalism in its popular variety helps to reinforce the identities. This study considers the power relationship between people and cultures. The roles and the identities are changing throughout history. Nowadays Islamic culture is one of popular subjects to study on. So, the Muslim world and revival of Islamic culture are the beginning of Occidentalism. Occidentalism is developed in the Orient in order to study the West from a non-Western World point of view. It can be referred as revival of identity (for isteghrab in Arab world by Hasan Hanafi or Talibanian or ISIS Occidentalists movements which stand for empowering Arab culture, Wahhabism or Salafism. All are revivalist movements to rapture Islamism as an ideology. This article tries to focus on the concept of Occidentalism in Iran after Iran Cultural Revolution.

    The 12-gene Recurrence Score assay is a validated predictor of recurrence risk in stage II and III colon cancer patients. We conducted a prospectively designed study to validate this assay for prediction of recurrence risk in stage II and III rectal cancer patients from the Dutch Total Mesorectal Excision (TME) trial. RNA was extracted from fixed paraffin-embedded primary rectal tumor tissue from stage II and III patients randomized to TME surgery alone, without (neo)adjuvant treatment. Recurrence Score was assessed by quantitative real time-polymerase chain reaction using previously validated colon cancer genes and algorithm. Data were analysed by Cox proportional hazards regression, adjusting for stage and resection margin status. All statistical tests were two-sided. Recurrence Score predicted risk of recurrence (hazard ratio [HR] = 1.57, 95% confidence interval [CI] = 1.11 to 2.21, P = .01), risk of distant recurrence (HR = 1.50, 95% CI = 1.04 to 2.17, P = .03), and rectal cancer-specific survival (HR = 1.64, 95% CI = 1.15 to 2.34, P = .007). The effect of Recurrence Score was most prominent in stage II patients and attenuated with more advanced stage (P(interaction) ≤ .007 for each endpoint). In stage II, five-year cumulative incidence of recurrence ranged from 11.1% in the predefined low Recurrence Score group (48.5% of patients) to 43.3% in the high Recurrence Score group (23.1% of patients). The 12-gene Recurrence Score is a predictor of recurrence risk and cancer-specific survival in rectal cancer patients treated with surgery alone, suggesting a similar underlying biology in colon and rectal cancers. © The Author 2014.

    2014-01-01

    The rate of radiation pneumonitis (RP) for patients receiving chemoradiotherapy has been various across studies. Whether it is related to different chemotherapy schedules used in combination with radiation therapy were evaluated in this study. New factors associated with RP were also investigated. A total of 369 consecutive patients with Stage III non small cell lung cancer treated with chemoradiotherapy were followed after radiotherapy (RT). Among them 262 patients received concurrent chemoradiotherapy followed by consolidation chemotherapy and 107 patients received only sequential chemotherapy after RT. RP was graded according to Common Terminology Criteria for Adverse Events version 4.0. The rate of grade ≥ 2 were 39.7%, 31% and 33.6% in the concurrent DP (docetaxel/cisplatin), concurrent NP (vinorelbine/cisplatin) and sequential group, and grade ≥ 3 RP were 18.4%, 9.5%, and 11.2% respectively. The rate of grade ≥ 3 RP was significantly higher in concurrent DP group than that in concurrent NP group (p = 0.04). RP occurred earlier in concurrent DP group than that in the other two groups. There were no significant differences in response rate among the three groups. In the multivariate analysis, age (OR = 1.99, p = 0.038 and OR = 8.90, p < 0.001), chemotherapy schedule (OR = 1.45, p = 0.041 and OR = 1.98, p = 0.013), mean lung dose(OR = 1.42, p < 0.001 and OR = 1.64, p < 0.001), and planning target volume(OR = 1.004, p = 0.001 and OR = 1.005, p = 0.021) were predictors for both grade ≥ 2 and grade ≥ 3 RP. Response to treatment was a new predictor for grade ≥ 3 RP only (OR = 4.39, p = 0.034). Response to treatment was found to be a new predictor for grade ≥ 3 RP. Compared to concurrent NP schedule, concurrent DP schedule achieved similar response to treatment but resulted in a higher risk of grade ≥ 3 RP

    On 23 September 1993, the Canadian Occidental Petroleum Company initiated the export of 120,000 b/d (barrels a day) of low sulphur, medium gravity crude oil from its Masila Block concession in Yemen. The oil is transported from Masila via a pipeline built by CanOxy and its partners to a new terminal at Ash Shihr, near Mukalla, in the Gulf of Aden. CanOxy is the third operator oil company to produce oil commercially in Yemen. The first, the Hunt Oil Company, began production in December 1987 and its output now totals about 187,000 b/d. The second, Nimir Petroleum, a Saudi venture which took over the facilities developed in the 1980s by two Soviet companies, is currently producing about 10,000 b/d and expects to increase its output to 25,000 b/d during this year.

    Full Text Available Abstract Background The rising prevalence of obesity and metabolic syndrome (MetS has received increased attention since both place individuals at risk for Type II diabetes and cardiovascular disease. Insulin resistance (IR has been implicated in the pathogenesis of obesity and MetS in both children and adults and is a known independent cardiovascular risk factor. However measures of IR are not routinely performed in children while MetS or severe obesity when present, are considered as clinical markers for IR. Objective The study was undertaken to assess the utility of ATPIII defined metabolic syndrome (MetS and severe obesity as predictors of insulin resistance (IR in a group of 576 overweight children and adolescents attending a pediatric obesity clinic in Brooklyn. Methods Inclusion criteria were children ages 3–19, and body mass index > 95th percentile for age. MetS was defined using ATP III criteria, modified for age. IR was defined as upper tertile of homeostasis model assessment (HOMA within 3 age groups (3–8, n = 122; 9–11, n = 164; 12–19, n = 290. Sensitivity, specificity, positive predictive values and odds ratios (OR with 95% confidence intervals (CI were calculated within age groups for predicting IR using MetS and severe obesity respectively. Results MetS was present in 45%, 48% and 42% of the respective age groups and significantly predicted IR only in the oldest group (OR = 2.0, 95% CI 1.2, 3.4; p = .006. Sensitivities were Conclusion The expression of IR in overweight children and adolescents is heterogeneous and MetS or severe obesity may not be sufficiently sensitive and specific indicators of insulin resistance. In addition to screening for MetS in overweight children markers for IR should be routinely performed. Further research is needed to establish threshold values of insulin measures in overweight children who may be at greater associated risk of adverse outcomes whether or not MetS is present.

    Full Text Available The alloy of copper with tin is used to show cultural relations and exchanges between Bronze Age cultures in western and central Europe. At the beginning, the distribution and location of tin resources explains the variations in bronze composition, but interregional ex-change leads later to a more homogeneous alloy. During the Early Bronze Age the Iberian Peninsula was not connected to the exchange networks of western Europe, and the first true bronzes appear at least two centuries la ter. The tin alloy spread over Iberia from north to south, and arrive to South-east at the end of the Middle Brome Age, due to the isolation of this region.

    A través del uso de la aleación de cobre y estaño en la tecnología metalúrgica de la Edad del Bronce europea se analizan las relaciones culturales e intercambios que tienen lugar entre los diversos grupos culturales. Al principio la disponibilidad de recursos minerales de estaño condicionó la composición de la aleación, pero más tarde el establecimiento de relaciones comerciales condujo a una mayor homogeneización en la producción. La Península Ibérica aparece durante el Bronce Antiguo desconectada de las interacciones actuantes en el Occidente de Europa, acusando un retraso en el conocimiento del bronce de al menos dos siglos. La difusión de la aleación se produce de norte a sur, llegando al Sureste a fines del Bronce Medio como consecuencia de su aislamiento.

    The difference in proximal alveolar bone height between 1970 and 1980, the /sup A/BD index/sup ,/ has been measured longitudinally in radiographs from an unselected material. The group constitutes 406 individuals born in 1904 - 1952 in the county of Stockholm. 13 of 18 predictors determined in 1970 were significantly related to the ABD index in the simple correlation analyses. The predictor /sup t/he alveolar bone loss 1970/sup /(ABL index 1970) had the strongest correlation to the ABD index. In the stepwise multiple regression analysis the predictor ABL index 1970 and three other predictors reached significant levels. These were age, number of lost teeth and Russell's Periodontal Index. 21 refs.

    Purpose: The role of consolidative radiation therapy (RT) for stage III and IV diffuse large B-cell lymphoma (DLBCL) in the era of rituximab is not well defined. There is evidence that some patients with bulky disease may benefit, but patient selection criteria are not well established. We sought to identify a subset of patients who experienced a high local failure rate after receiving rituximab-based chemotherapy alone and hence may benefit from the addition of consolidative RT. Methods and Materials: Two hundred eleven patients with stage III and IV DLBCL treated between August 1999 and January 2012 were reviewed. Of these, 89 had a complete response to systemic therapy including rituximab and received no initial RT. Kaplan-Meier analysis and Cox proportional hazards regression were performed, with local recurrence (LR) as the primary outcome. Results: The median follow-up time was 43.9 months. Fifty percent of patients experienced LR at 5 years. In multivariate analysis, tumor ≥5 cm and stage III disease were associated with increased risk of LR. The 5-year LR-free survival was 47.4% for patients with ≥5-cm lesions versus 74.7% for patients with <5-cm lesions (P=.01). In patients with <5-cm tumors, the maximum standardized uptake value (SUVmax) was ≥15 in all patients with LR. The 5-year LR-free survival was 100% in SUV<15 versus 68.8% in SUV≥15 (P=.10). Conclusions: Advanced-stage DLBCL patients with stage III disease or with disease ≥5 cm appear to be at an increased risk for LR. Patients with <5-cm disease and SUVmax ≥15 may be at higher risk for LR. These patients may benefit from consolidative RT after chemoimmunotherapy.

Patients with <5-cm disease and SUVmax ≥15 may be at higher risk for LR. These patients may benefit from consolidative RT after chemoimmunotherapy

    The KRAS gene frequently mutates in colorectal cancer (CRC). Here we investigated the prognostic and predictive role of KRAS mutation in patients with stage II or III CRC. A consecutive cohort of patients with stage II or III CRC from a single center database was studied. The association between KRAS status, adjuvant FOLFOX therapy, and 3-year disease-free survival (3-y DFS) was analyzed. Of our 433 patients, 166 (38.3%) exhibited the KRAS mutation. Among the 190 patients who did not receive adjuvant therapy, those with KRAS mutation tumors had a worse 3-y DFS (hazard ratio [HR], 1.924; 95% confidence interval [CI], 1.078-3.435; P = 0.027). Among patients who received adjuvant chemotherapy, KRAS mutation was not correlated with worse 3-y DFS (HR, 1.083; 95% CI, 0.618-1.899; P = 0.781). Adjuvant chemotherapy improved 3-y DFS only among patients with KRAS mutant tumors (78.0% vs 69.2%) on multivariate analysis adjusted for age, stage, grade, site, vessel invasion, and carcinoembryonic antigen level (HR, 0.454; 95% CI, 0.229-0.901; P = 0.024). In contrast, there was no benefit of adjuvant chemotherapy in the KRAS wild-type group (84.3% vs 82.0%). KRAS mutation indicates poor prognosis. FOLFOX adjuvant chemotherapy benefits patients with stage II or III colorectal cancer with KRAS mutant tumors and is worth further investigation.

    Full Text Available Fish for Every Family Project (FFEFP is one of the initiatives of Plan International that responds to the issue of malnutrition among Filipino children. FFEFP aims to promote and develop backyard tilapia fish farming in Isabela, Mindoro Occidental, Southern Leyte, and Western Samar, Philippines. These are the areas in the country where malnutrition is commonly observed. This study explores the adoption to The Fish for Every Family Project (FFEFP, and assesses its impacts in different levels. This impact assessment of FFEFP was conducted in Occidental Mindoro. The researchers used purposive sampling to touch base directly with a representative sample of the FFEFP beneficiaries in three out of four municipalities in Mindoro Occidental. The data were gathered through focus group discussions with the key officials in the area and some tilapia cage culture technology adopters. Key informant interviews (KIIs of all project stakeholders were also conducted as well. In order to validate the information gathered from the respondents and to see the fish farms used, field visits and ocular inspection were made. The study revealed that the FFEFP has various impacts to the beneficiaries, adopters, and replicators of tilapia. The impacts occurred at three levels: individual, family, and community. It was found out that the project was able to provide self-satisfaction among the beneficiaries and build stronger relationships among the members of the family and of the community.

    Full Text Available Por muito tempo o “marxismo ocidental” celebrou a sua superioridade em relação ao marxismo dos países que se remetiam ao socialismo e que estavam todos situados no Oriente. Em decorrência dessa atitude arrogante, o marxismo ocidental nunca se empenhou seriamente em repensar a teoria de Marx à luz de um balanço histórico concreto: qual era o papel do Estado e da nação nesses países e no “campo socialista”? Como promover a democracia e os direitos humanos e como estimular o desenvolvimento das forças produtivas e o bem-estar das massas numa situação caracterizada pelo bloqueio capitalista? Ao invés de pôr-se essas questões difíceis, o marxismo ocidental preferiu abandonar-se à cômoda atitude autoconsolatória de quem cultiva em particular as suas utopias e rejeita, como uma contaminação, o contato com a realidade e a reflexão sobre a realidade. Disso derivou uma progressiva capitulação à ideologia dominante. Por fim, a autocelebração do marxismo ocidental desembocou na sua autodissolução. Palavras-chave: Marxismo ocidental. Campo socialista. Falta de balanço histórico. Autodissolução. For a long time the “occidental Marxism” celebrated its superiority over the Marxism established in countries located in the Orient, to where the socialism was related. Due to this arrogante attitude, the occidental Marxism has never endeavored to rethink Marx’s theory upon a concrete historical summary: what was the role of the State and Nation in these countries and in the “socialist field”? How to promote the democracy and the human rights and how to estimulate the development of the productive forces and people’s welfare within a situation featured by the capitalist interdiction? Instead of opposing to those difficult questions, the occidental Marxism preferred to remain at a comfortable and self-consolating attitude, cultivating their particular utopias and rejecting, as a contamination, the contact to and

    Recent studies have suggested that EES may reduce ST compared to PES, but no individual trial has been adequately powered for this endpoint. The incidence of stent thrombosis, as well as the impact of dual antiplatelet therapy (DAPT) discontinuation during the first two years following everolimus-eluting stent (EES) and paclitaxel-eluting stent (PES) deployment were therefore analysed from a pooled, patient-level database derived from four randomised clinical trials. Data from the SPIRIT II, SPIRIT III, SPIRIT IV and COMPARE trials (n=6,789 patients) were analysed. Two-year ST rates were determined using time-to-event methods and compared with the log-rank test. ST rates were also determined after DAPT discontinuation. EES compared to PES significantly reduced the two-year rates of ST (0.7% versus 2.3%, p=0.0001), including the interval rates of ST up to 30 days (0.2% versus 1.0%, p<0.0001), between 31 days and one year (0.2% versus 0.6%, p=0.02), and after one year (0.3% versus 0.8%, p=0.001). EES also reduced the two-year composite rate of cardiac death or MI (4.0% versus 6.6%, p=0.0001). Increased rates of ST after DAPT discontinuation beyond six months were observed in the PES cohort, but not in the EES cohort. In this large pooled analysis from four randomised trials, treatment with EES compared to PES significantly reduced the rates of ST through two years of follow-up, with a concomitant reduction in cardiac death or MI. DAPT discontinuation beyond six months may be safe with EES.

    Biological diversity can be defined as variability among living organisms from all sources, including terrestrial organisms, marine and other aquatic ecosystems, and the ecological complexes which they are part of. This includes diversity within species, between species, and of ecosystems. Numerous diversity indices combine richness and evenness in a single expression, and several climate-based explanations have been proposed to explain broad-scale diversity patterns. However, climate-based water-energy dynamics appears to be an essential factor that determines patterns of diversity. The Mexican Sierra Madre Occidental occupies an area of about 29 million hectares and is located between the Neotropical and Holarctic ecozones. It shelters a high diversity of flora, including 24 different species of Pinus (ca. 22% on the whole), 54 species of Quercus (ca. 9–14%), 7 species of Arbutus (ca. 50%) and many other trees species. The objectives of this study were to model how tree species diversity is related to climatic and geographic factors and stand density and to test the Metabolic Theory, Productivity-Diversity Hypothesis, Physiological Tolerance Hypothesis, Mid-Domain Effect, and the Water-Energy Dynamic Theory on the Sierra Madre Occidental, Durango. The results supported the Productivity-Diversity Hypothesis, Physiological Tolerance Hypothesis and Water-Energy Dynamic Theory, but not the Mid-Domain Effect or Metabolic Theory. The annual aridity index was the variable most closely related to the diversity indices analyzed. Contemporary climate was found to have moderate to strong effects on the minimum, median and maximum tree species diversity. Because water-energy dynamics provided a satisfactory explanation for the patterns of minimum, median and maximum diversity, an understanding of this factor is critical to future biodiversity research. Quantile regression of the data showed that the three diversity parameters of tree species are generally higher in cold

    L'étude lithostratigraphique en sédimentologique des formations du Cambrien inférieur de l'Anti-Atlas occidental (Maroc) a permis de mettre en évidence la diversité extrême des faciès allant des faciès continentaux jusqu'au faciès franchement marins. La répartition verticale de ces faciès ainsi que leurs associations ont permis de (i) proposer un nouveau découpage de la succession en formations lithostratigraphiques, (ii) reconstituer les milieux de dépôt (système fluviatile, lacs, fan-deltas, milieu littoral, plate-forme dominée par des constructions stromatolitiques et récifales et plate-forme dominée par les tempêtes) et (iii) établir des modèles paléogéographiques retraçant les différentes étapes d'évolution de ce bassin qui fait partie de la plate-forme nord-gondwanienne au Cambrien inférieur. Lithostratigraphical and sedimentological studies of the Early Cambrian formations in the western Anti-Atlas (Morocco) evidence their large diversity of facies ranging from continental to clearly marine. Vertical distribution and associations of facies afford opportunities to (i) suggest a new classification of the sedimentary sequence in terms of lithostratigraphic formations, (ii) restore the depositional environments (fluvial system, lake, delta fan, coast, stromatolite and reef-dominated platform, tempest-dominated platform), and (iii) establish palæogeographic models displaying the different evolutionary stages of this basin that constituted a part of the Lower Cambrian north-Gondwanian platform.

    Full Text Available Hagiographical literature in Western Islam is abundant from the 12th-13th centuries onward, and is tied to the introduction and expansión of sufism in al-Andalus and Morocco. In this paper I analyse three hagiographical texts from al-Andalus in order to understand how the authority of a holy man is constructed from two perspectives: fear of his miraculous power and love inspired in his followers. Through these two passions, love and fear, one can infer the existence of a political and religious pattern for authoritarian relationships in Western Islam.Los siglos XII y XIII son fundamentales para la expansión del sufismo en el Occidente musulmán y para la creación de una tradición hagiográfica puramente magrebí. En este artículo se utilizan tres textos hagiográficos andalusíes de esa época para analizar cómo se construye la autoridad del hombre santo desde una doble perspectiva: la del miedo a la acción del santo y la del amor que inspira. A través de estas pasiones se puede rastrear la existencia de un modelo de autoridad que es a la vez religioso y político.

Fishing and marketing practices in both areas were also documented and population biology information noted.Compared to earlier conditions, present fishing patterns show a worsened stage of overexploitation primarily characterized by collection of predominantly small and immature (mostly <45 mm shell lengths sizes. Intensity/duration and location of fishing also varied due to both abundance and demand factors.The difference in sizes of clams and the varying fishing durations in each area suggest a non-uniform pattern of settlement resulting most likely from differential larval recruitment, the likely factors causing the local boom and bust fishery. The larger and long term extent of the effect of these factors can only be further investigated by parallel 2-3 year fishery-dependent and -independent surveys

    Aquifers provide a reliable freshwater source in arid and semiarid regions, where droughts are common and irrigated crops present significant water requirements, so intensive pumping is generally needed. Over-extraction leads to dropping water tables, which in turn threatens the survival of groundwater-dependent ecosystems and water supplies. This calls for strategies to channel hydrological, environmental, agricultural, political and social change. Based on the experience of the Mancha Occidental aquifer, Spain, this paper explores some of the complexities of managing groundwater, dealing with the long-term changes that intensive groundwater use has generated in the region. The Mancha experience shows how environmental conservation may drive social and economic change at the regional scale for periods spanning several decades. What makes this case study unique, however, is the combination of social and environmental conflicts, most of which stem from the prevalence of illegal water use, and their detrimental effect on Ramsar wetlands. The situation exposed a paradox, namely that subsidies for farmers to cut down on water use were actually detrimental to the welfare of groundwater-dependent ecosystems. The unexpected (and timely) occurrence of extreme rainfall events in recent times, after 40 years of ineffective management measures and sustained environmental degradation, enabled the aquifer and its associated wetlands to recover spectacularly to a near-pristine condition. As groundwater-dependent wetlands are highly sensitive ecosystems, it is concluded that it is up to society to decide how much environmental damage can be tolerated in exchange for the social and economic benefits of groundwater-based development.

    Saline water is easily identified by measurement of the conductivity of the ionic species in the water. In groundwater, it is important to identify the mechanism of salinization for proper management of the resource. Salinization may come from: a) leaching of salts by percolating water, b) intrusion of modern saltwater bodies of connate water, and c) concentration of dissolved salts due to evaporation. The salinity and isotopic concentrations of 18 O, 2 H, and 3 H of the water sources were used to assess the processes which lead to the salinization of groundwater in Bacolod City, Negros Occidental. The isotopic composition of deep groundwater, river water, and springs cluster along the LMWL with δ 18 O ranging from -7.9 ''promille'' to -6.5 ''promille'' and δ 2 H ranging from -52.6 ''promille'' to -39.1''promille''. Two isotopically distinct groups of deep groundwater were deleated; the higher elevation wells yielding isotopically depleted waters while the lowland wells yielding relatively enriched water with higher conductivity. The shallow coastal wells exhibited more enriched isotope values with δ 18 O values from 6.10 ''promille''-5.61''promille'' and δ 2 H from -43.1''promille'' to -38.8''promille'' and highest conductivity. The relative enrichment in the isotopic composition of the deep groundwater in the lowland and the shallow groundwater along the coast is attributed to saltwater intrusion. The process of salinization in these waters is differentiated based on the relationship between their isotopic compositions and the chlorine concentrations. The high salinity of the isotopically enriched and old deep groundwater inland is attributed to mixing with connate water. On the other hand , mixing with modern sea water is evident in the deep and shallow coastal wells. (author)

    Full Text Available Taking for granted that the Catalan-Aragonese expansion through the Mediterranean sea has received due attention from historians, this work deals with some realms and locations less often visited by sailors and merchants from Catalonia, Valencia or Mallorca. Its aim is to provide a view of the Catalan presence in western Andalusia throughout the late Middle Ages, analyzing its role in the Andalusian allotment and the conditions accounting for the development of such a presence in the region between the thirteenth and the fifteenth centuries. It deals particularly with the creation of family and economic bonds standing as the foundations of Catalan influence on Andalusia, which help to better understand its interest in the Middle Atlantic some time later.

    Tomada como punto de partida la idea de que la historiografía conoce bastante bien la expansión catalanoaragonesa por distintos puntos del Mediterráneo, este trabajo pretende acercarse a otros ámbitos menos frecuentados por marinos y comerciantes de aquel reino, aunque no por ello es menos importante para el desarrollo económico de Cataluña, Valencia o Mallorca. Así, el objetivo de este artículo es ofrecer una muestra de lo que fue la presencia catalana en la Andalucía Occidental a lo largo de los siglos finales de la Edad Media, analizando su participación en los repartimientos andaluces, las condiciones que afectaron al desarrollo de su presencia en la región entre los siglos XIII-XV, así como prestar una especial atención a la formación de los vínculos familiares y económicos que cimentaron su influencia en Andalucía y ayudan a explicar mejor su posterior interés por el Atlántico Medio.

    Toxicity from chemotherapy is highly variable, unpredictable and results in substantial morbidity and increased healthcare costs. New predictors of toxicity are required to improve the safety and efficacy of chemotherapy. Inflammatory or B symptoms in lymphoma are associated with elevated plasma inflammatory markers and predict worse treatment response and survival. Recent data suggest that systemic inflammation results in reduced hepatic drug metabolism and increased toxicity from chemotherapy. We investigated whether B symptoms were associated with greater toxicity in patients treated for non-Hodgkin lymphoma (NHL). The British National Lymphoma Investigation compared two chemotherapy regimens in older patients with aggressive NHL. Approximately 50% of patients had B symptoms. Demographic and toxicity data on 664 patients were analysed to identify predictors of toxicity by multivariate analysis, with particular reference to B symptoms. Using univariate analyses, severe (grades 3–4) leucopenia, anaemia, thrombocytopenia, nausea and vomiting and diarrhoea occurred more frequently in patients with B symptoms. The associations between B symptoms and severe leucopenia (OR 1.7, p = 0.005) and anaemia (OR 2.3, p = 0.025) persisted after adjustment for other prognostic factors in multivariate analyses. The use of granulocyte colony stimulating factor reduced neutropenia in patients with both A and B symptoms. For the first time and in a large NHL cohort we have shown that inflammatory symptoms are independent predictors for myelosuppression from chemotherapy. These data will enable improved prognostication for toxicity and provide individualisation of therapy in NHL and other tumours. These findings also create the potential for strategies used prior to chemotherapy aimed at reducing systemic inflammation in order to improve drug metabolism and reduce treatment-related toxicity.

    The Sierra Madre Occidental (SMO) volcanic province is characterized by voluminous silicic ignimbrites that reach an accumulated thickness of 500 to 1500 m. A single ignimbrite can reach up to 350 m thick in its outflow facies. This ignimbrite sequence formed mostly within 38-23 Ma, building up a total estimated volume of ca. 580,000 km3 making the SMO the largest ignimbrite province of the world. We have showed that several and probably most of the SMO ignimbrites were erupted from fissures associated to Basin and Range fault systems or grabens (Geology, 2003), thus naming these volcano-tectonic structures as graben calderas (Caldera Volcanism book, Elsevier, 2008). Generally, the sequence observed in graben calderas include, from oldest to youngest, alluvial fan deposits combined with lacustrine deposits, pyroclastic surge deposits and minor volume ignimbrites, a large-volume ignimbrite that could be massive or made of successive layers, and sometimes silicic lava domes and/or mafic fissural lavas both with vents aligned with the graben trend. Fallout deposits, plinian or non-plinian, are not observed in the sequence. Thus, onset of caldera collapse represented by the major ignimbrite must occur just after deposition of continental sediments within the graben domain. A similar volcano-tectonic development is observed in pull-apart grabens. Therefore, extensional or transtensional tectonics, before and during caldera collapse, and the emplacement of a subgraben shallow silicic magma chamber are the necessary conditions for the development of graben calderas. We describe here the case of the Guanajuato graben caldera, located in the central part of Mexico and in the southeastern portion of the SMO volcanic province. The caldera is part of the economically important mining district of Guanajuato, with 28 silver mines, some active since the 16th century. The caldera structure, a rectangle of 10 x 16 km, was controlled by NW and NE regional fault systems. Most ore

    This study aimed to validate previously reported dosimetric parameters, including thyroid volume, mean dose, and percentage thyroid volume, receiving at least 40, 45 and 50 Gy (V40, V45 and V50), absolute thyroid volume spared (VS) from 45, 50 and 60 Gy (VS45, VS50 and VS60), and clinical factors affecting the development of radiation-induced hypothyroidism (RHT). A post hoc analysis was performed in 178 euthyroid nasopharyngeal cancer (NPC) patients from a Phase III study comparing sequential versus simultaneous-integrated boost intensity-modulated radiation therapy. RHT was determined by increased thyroid-stimulating hormone (TSH) with or without reduced free thyroxin, regardless of symptoms. The median follow-up time was 42.5 months. The 1-, 2- and 3-year freedom from RHT rates were 78.4%, 56.4% and 43.4%, respectively. The median latency period was 21 months. The thyroid gland received a median mean dose of 53.5 Gy.

    Background and purpose: This secondary analysis was performed to identify predictive factors for severe late radiotherapy (RT)-related toxicity after treatment with hyperfractionated RT +/− concomitant cisplatin in locally advanced head and neck cancer. Materials and methods: Patients were retrospectively analyzed from the previously reported randomized phase III trial: SAKK 10/94. Severe late RT-related toxicity was defined as late RTOG ⩾ grade 3 toxicity starting 3 months after end of RT and/or potential treatment-related death within 3 years of randomization. Results: Two hundred and thirteen randomized patients were analyzed; 84 (39%) experienced severe late RT-related toxicity. With median follow-up of 9.7 years (range, 0.4–15.4 years), median time to severe late RT-related toxicity was 9.6 years. In the univariate Cox proportional hazards model the following variables were associated with severe late RT-related toxicity: advanced N-classification (p < 0.001); technically unresectable disease (p = 0.04); weight loss ratio (p = 0.003); supportive measures (p = 0.009) and severe acute dysphagia (p = 0.001). In the subsequent multivariate analysis all variables except use of supportive measures remained statistically significant. Conclusions: Chemotherapy did not appear to affect severe late RT-related toxicity, but advanced N-classification, technically unresectable disease, weight loss ratio, and severe acute dysphagia were independent predictive factors for severe late RT-related toxicity.

    Surgery is a curative treatment for patients with locally advanced colon cancer, but recurrences are frequent for those with stage III disease. FOLFOX adjuvant chemotherapy has been shown to improve recurrence-free survival and overall survival by more than 20% and is nowadays considered a standard of care. However, the vast majority of patients will not benefit from receiving cytotoxic drugs because they have either already been cured by surgery or because their tumor cells are resistant to the chemotherapy, for which predictive factors are still not available. Identifying which patients are unlikely to respond to adjuvant chemotherapy from among those who are eligible for such treatment would be a major step towards treatment personalization. It would spare such patients from unnecessary toxicities and would improve the allocation of societal healthcare resources. PePiTA is a prospective, multicenter, non-randomised trial built on the hypothesis that preoperative chemosensitivity testing using FDG-PET/CT before and after one course of FOLFOX can identify the patients who are unlikely to benefit from 6 months of adjuvant FOLFOX treatment for stage III colon cancer. The study’s primary objective is to examine the ability of PET/CT-assessed tumor FDG uptake after one course of preoperative chemotherapy to predict the outcome of adjuvant therapy, as measured by 3-year disease-free survival. Secondary objectives are to examine the predictive value of changes in PET/CT-assessed tumor FDG uptake on overall survival, to define the best cut-off value of FDG uptake for predicting treatment outcome, and to analyse the cost-effectiveness of such preoperative chemo-sensitivity testing. At study planning, exploratory translational research objectives were 1) to assess the predictive value of circulating tumor cells for disease-free survival, 2) to examine the predictive value of single nucleotide polymorphisms for disease-free survival with respect to genes related either to

    Full Text Available The subject of the failed uprisings of February, 1895 in Cuba´s West has been a controversial matter among historians for almonst as long ago as the events themselves. A number of Cuban scholars, as well as the accounts of people who participated in the uprisings, have not helped to the search for the truth. The reasons for this controversy are very much related to the hypothetical relevance of an all-out rebellion emerging just a short distance from Cuba´s capital, which would have accelerated the independence movement and changed the conflict's outcome. While in a previous work on Cuban banditry I insisted on the critical importance of these uprisings, in this paper I intend to call attention to new data on them, particularly on their most relevant aspect: the role played by the Cuban general Julio Sanguily y Garritte. He has been blamed for the failure of the western revolt, on account of the death of rebel officer -and former social bandit- Manuel García Ponce.

    El tema de los fracasados alzamientos insurreccionales del occidente cubano, en febrero de 1895, ha sido objeto de un largo debate historiográfico desde pocos años después de su acaecimiento. Diversos estudiosos cubanos, así como los testimonios de los propios protagonistas de los hechos han contribuido, en numerosas ocasiones, a hacer aún más difícil la búsqueda de la verdad. Las razones de esta polémica están profundamente relacionadas con la hipotética relevancia de un levantamiento en toda regla a escasos kilómetros de la capital cubana, lo que, en teoría, hubiera acelerado el proceso emancipador y cambiado, de diversas maneras, el devenir de la contienda que se saldó con la pérdida de Cuba para España. En nuestro trabajo sobre el bandolerismo cubano (1, insistimos en la importancia crucial de tales acontecimientos y, en esta ocasión, nos proponemos aportar nuevos datos sobre los hechos mencionados, particularmente sobre su aspecto más relevante: el

    Full Text Available Species distribution models (SDMs help identify areas for the development of populations or communities to prevent extinctions, especially in the face of the global environmental change. This study modeled the potential distribution of the tree Picea chihuahuana Martínez, a species in danger of extinction, using the maximum entropy modeling method (MaxEnt at three scales: local, state and national. We used a total of 38 presence data from the Sierra Madre Occidental. At the local scale, we compared MaxEnt with the reclassification and overlay method integrated in a geographic information system. MaxEnt generated maps with a high predictive capability (AUC > 0.97. The distribution of P. chihuahuana is defined by vegetation type and minimum temperature at national and state scales. At the local scale, both models calculated similar areas for the potential distribution of the species; the variables that better defined the species distribution were vegetation type, aspect and distance to water flows. Populations of P. chihuahuana have always been small, but our results show potential habitat greater than the area of the actual distribution. These results provide an insight into the availability of areas suitable for the species’ regeneration, possibly through assisted colonization.

    Full Text Available Una idea generalizada y bastante aceptada en torno a la introducción del Castaño, Castanea sativa, en el área occidental del Mediterráneo y concretamente en la Península es la que sostiene que esta especie fue extendida por los romanos quienes tomándola en su zona de origen, Asia menor y Caucaso, la naturalizaron en toda la Europa mediterránea hasta llegar a la Península Ibérica. Muchos autores modernos en sus publicaciones, al hablar del Castaño, siguen haciendo mención a lo expuesto anteriormente (JONKER, 1952; STRASBURGER, 1894; LANZARA y PIZZETTI, 1977 y FONT QUER, 1961 entre otros. Sin embargo, parece que los datos que la palinología y el estudio de carbones han aportado en investigaciones realizadas en yacimientos arqueológicos y turberas constatan la presencia del Castaño en épocas muy anteriores a la de la expansión romana.

    A total of 1,356 kidney transplants has been performed in the Hospital de Especialidades del Centro Médico Nacional de Occidente, IMSS, in Guadalajara Mexico, including 935 in the past 8 years. This represents an important increase of this activity in our country. Of the total transplants, 1,218 (90%) were from living donors and only 138 (10%) were from cadaveric donors, a number that we hope to increase. Most recipients were young adults, with an average age of 31 years old. The overall one-year graft and patient survival rates for living-donor kidney recipients were 90% and 82%, and for cadaveric kidney recipients they were 80% and 70%, respectively. Acute rejections occurred in 17% and chronic allograft nephropathy was diagnosed in 7% of our kidney transplant recipients. The main cause of patient death was infection, frequently invasive CMV. Cardiovascular complications were a relatively infrequent cause of death as has been seen in other international series. Hepatitis B and C have been widley studied. Hepatitis C is the most prevalent viral infection in our population. Both living and cadaveric donors in our series were young, which may explain the good results. We have had very few complications among living donors and no mortality. Two donors developed chronic renal insufficiency after the kidney donation (0.001%). This excellent safety record reflects the experience of our team. We hope to increase the number of cadaveric transplant donors with the renewed interest in enlarging the transplantation programs in Mexico while maintaining our high percentage of living donors in order to benefit more patients.

    Full Text Available Les observations de terrain sont fondamentales en télédétection. Selon la finalité de l’étude, la description des paysages observés sera plus ou moins détaillée. Une simple reconnaissance des principaux postes d’occupation du sol demande peu d’indicateurs et ne nécessite pas une localisation à la tachèle près. En revanche, l’analyse du contenu des pixels en vue d’une modélisation statistique s’appuie sur une description thématique détaillée de points localisés très précisément. Dans ce cas les images utilisées doivent être correctement géoréférencées et la localisation sur le terrain se fait à l’aide d’un GPS différentiel. Restent les problèmes du choix des points à analyser ainsi que celui de l’observation elle-même de leur "contenu". Nous présentons dans cet article une méthode qui vise à répondre à ces deux questions. Notre approche est fondée sur la technique du sondage systématique non-aligné. Cette dernière permet de tenir compte à la fois de la valeur des points observés et de leur localisation pour définir le plan d’échantillonnage.

    Full Text Available Mangroves have a lot of economic and ecological advantages which include coastal protection, habitat for wildlife, fisheries and forestry products. Determination of the extent of mangrove patches in the coastal areas of the Philippines is therefore important especially in resource conservation, protection and management. This starts with a well-defined and accurate map. LiDARwas used in the mangrove extraction in the different coastal areas of Negros Occidental in Western Visayas, Philippines. Total coastal study area is 1,082.55 km² for the 14 municipalities/ cities processed. Derivatives that were used in the extraction include, DSM, DTM, Hillshade, Intensity, Number of Returns and PCA. The RGB bands of the Orthographic photographs taken at the same time with the LiDAR data were also used as one of the layers during the processing. NDVI, GRVI and Hillshade using Canny Edge Layer were derived as well to produce an enhanced segmentation. Training and Validation points were collected through field validation and visual inspection using Stratified Random Sampling. The points were then used to feed the Support Vector Machine (SVM based on tall structures. Only four classes were used, namely, Built-up, Mangroves, Other Trees and Sugarcane. Buffering and contextual editing were incorporated to reclassify the extracted mangroves. Overall accuracy assessment is at 98.73% (KIA of 98.24% while overall accuracy assessment for Mangroves only is at 98.00%. Using this workflow, mangroves can already be extracted in a large-scale level with acceptable overall accuracy assessments.

  11. Predictor feedback for delay systems implementations and approximations

    CERN Document Server

    Karafyllis, Iasson

    2017-01-01

    This monograph bridges the gap between the nonlinear predictor as a concept and as a practical tool, presenting a complete theory of the application of predictor feedback to time-invariant, uncertain systems with constant input delays and/or measurement delays. It supplies several methods for generating the necessary real-time solutions to the systems’ nonlinear differential equations, which the authors refer to as approximate predictors. Predictor feedback for linear time-invariant (LTI) systems is presented in Part I to provide a solid foundation on the necessary concepts, as LTI systems pose fewer technical difficulties than nonlinear systems. Part II extends all of the concepts to nonlinear time-invariant systems. Finally, Part III explores extensions of predictor feedback to systems described by integral delay equations and to discrete-time systems. The book’s core is the design of control and observer algorithms with which global stabilization, guaranteed in the previous literature with idealized (b...

En las zonas palmeras Central (ZC y Oriental (ZE, las palmas enfermas pueden recuperarse naturalmente. En la Zona Occidental (ZW el proceso de recuperación no es evidente. La recuperación de palmas está ligada a gran actividad meristemática que podría involucrar la acción inductora de metabolitos como las poliaminas (PA. Este trabajo muestra la relación entre poliaminas del meristemo y la capacidad de recuperación de palmas con PC, en dos zonas agroclimáticas diferentes. Poliaminas extraídas del meristemo de palmas sembradas en ZC y ZW, fueron analizadas por HPLC. En ZC, donde existe recuperación espontánea, los niveles más altos de PA se presentan en palmas sanas y en recuperación y a medida que avanza la enfermedad la concentración desciende hasta un mínimo en el estado de PC inicial (PCI. Luego la concentración de PA aumenta hasta el estado de Buena Recuperación (BR donde los valores de poliaminas son más altos que los de palmas sanas. En la ZW, con la enfermedad el contenido de PA aumenta llegando al máximo en plantas sin recuperación y el mínimo se presenta en plantas sanas. Las diferencias entre zonas pueden explicarse por diferentes roles de las poliaminas en plantas. En la ZC la cantidad elevada de PA en palmas sanas o en recuperación funcionaría en la inducción de actividad meristemática, para la recuperación espontánea. En la ZW el aumento en el contenido de PA con la enfermedad induciría la generación de especies reactivas de oxígeno para defensa secundaria de la planta ante la imposibilidad de, a través de incrementos en la actividad meristemática producir rápidamente estructuras sanas que no sean reinfectadas.

    Full Text Available La política exterior española durante la II Guerra Mundial empezó a virar hacia la neutralidad con la llegada de Gómez Jordana al Ministerio de Asuntos Exteriores en 1942. Sin embrago, la colaboración con el Eje, aún no concluida, provocó, fuertes presiones por parte de los aliados durante el resto de la guerra y alentó la sospecha de que aún continuaba el abastecimiento clandestino de submarinos alemanes en Canarias. Por ello. los aviones aliados sobrevolaron frecuentemente la Zona Aérea de Canarias y África Occidental entre principios de 1943 y el verano de 1944, provocando la reacción de las baterías de artillería antiaérea españolas e incluso la intervenci6n de los cazas con base en Gando. En ningún momento las fuerzas españolas intentaron derribar a los aviones aliados que atravesaban las aguas territoriales, sino sólo avisarlos para que se retiraran. No obstante, los aviones aliados persistieron, dando lugar a graves incidentes que estuvieron punto de ocasionar una fatalidad. Finalmente, las prolongadas gestiones diplomáticas emprendidas a finales de 1943 acabaron con estos incidentes, los cuales son un ejemplo olvidado de las tensas relaciones entre España y los aliados durante el declive del Eje.Spanish foreign policy through World War II turned to the way of neutrality after Gómez Jordana arrived at the Ministry of Foreign Affaires in 1943.  Howver, the persistent aid to tha Axis rose strong pressures by the Allies for the rest of the war and encouraged them for searching German U-boots at the Canary Islands. So Allied airplanes frequently flew over the Canary Islands and West Africa Aerial Zone between the beginning of 1943 and the summer of 1944, tempting the Spanish anti-aircraft batteries and the fighters based in Gaildo Gando reaction.

    DETERMINAR la evolución de la lanza es difícil, incluso en el área occidental. Fijar el período a que corresponde una determinada pieza con frecuencia implica los más graves problemas, y la posibilidad de error siempre está al acecho. Naturalmente, seriar cronológicamente lanzas de fecha determinada por hallazgos arqueológicos precisos: excavaciones de ruinas, tumbas, etc., es fácil. Pero aplicar los resultados que se obtienen con esta organización supuesta ya no lo es tanto. Ello se debe esencialmente a un hecho: la falta de caracterización estilística suficiente en gran número de piezas, aunque es innegable que hay otras cuya forma «dice» con claridad a qué mundo cultural pertenecen. Complementa esa falta de caracterización la riqueza tipológica que suele darse en cada período. El canon varía con libertad e igualmente las dimensiones e incluso la técnica. Para el coleccionista de lanzas, o para el investigador que se enfrenta con piezas que no proceden de hallazgos fechados, es muy arduo, pues, saber con aproximación a qué época y lugar corresponden tales armas. Tiene a su disposición varios elementos de juicio: la comparación con las armas procedentes de hallazgos fechados, la «calidad» (textura de la pieza, es decir, su aspecto táctil, que acaba por ser inconfundible o poco menos para el que frecuenta los objetos antiguos. Finalmente, por escasa que sea la «caracterización estilística», siempre hay alguna, y ayuda a corroborar o a rectificar las hipótesis formuladas con la base de los dos principios primeros.

    Painful sunburns at any age are one of the main risk factors for skin cancer. To determine the prevalence and predictors of sunburn among beachgoers. A cross-sectional health survey was conducted at the beach during the summer. Adults >18 years with an understanding of Spanish were interviewed using a questionnaire about behaviours, attitudes and knowledge related to sun exposure at the beach. A descriptive analysis was performed, and a log-binomial regression model was used to determine predictors of sunburn. The survey was completed by 1054 beachgoers, with a mean age of 43.8 (SD: 18.7) years, 61.2% women, skin phototypes i (13.6%), ii (22.3%), iii (34.0%) and iv (30.2%). 46.9% of responders reported at least one painful sunburn during the previous summer. Age, sex, education, skin phototype, midday sun exposure, sun protection habits, attitudes towards tanning and knowledge about skin cancer were identified as independent predictors of sunburn. It is necessary to develop photoprotection campaigns aimed at beachgoers, particularly in young people, men, those with skin phototypes I-III and secondary or university education. Educational strategies should be aimed at discouraging sun exposure at midday, changing attitudes towards tanning and improving knowledge about skin cancer. © 2017 John Wiley & Sons A/S.

    Full Text Available Hemos usado la teoría transcultural de los valores humanos desarrollada por Schwartz (1992a para analizar y comparar la jeararquía de valores de diez países de Europa occidental con respecto a la importancia de los valores en un conjunto de países del resto del mundo. Hemos encontrado que el conjunto de naciones de Europa Occidental comparten un perfil único de valores que las distingue del resto de los países. Este perfil se caracteriza por la alta prioridad que atribuyen a los valores de compromiso igualitario, autonomía intelectual y armonía y por la baja prioridad que otorgan a los valores de jerarquía y conservación. Estos resultados son explicados acudiendo a algunos factores socio-estructurales, políticos y económicos, compartidos por estos países y que les diferencian de los demás.

    The occidental Terrane is envisaged as the eastern/southeastern reworked margin of the Sao Francisco/Rio de la Plata plate associated with and E-trending subduction under the Congo plate. The Paraiba do Sul Klippe is part of the Oriental Terrane, envisaged as a portion of the Congo plate. A collisional-stage resulted in intense westward deformation of the Occidental Terrane under intermediate pressure metamorphism (syn-D1+D2 events). A late-collisional stage resulted in subvertical folding and steep shear zones (D3 event). Both stages were associated with voluminous crustal-derived granites. U-Pb and Sm-Nd geochronology as well as geochemical and structural data point to three magmatic episodes: a syn-collisional stage 1; a syn-collisional stage 2; and a late-collisional stage. This paper presents a magmatic evolutionary model for this crustal segment of the Ribeira orogenic belt based on new geological data of Brasiliano granites and data available in the literature.

    Full Text Available Abstract Background To investigate and compare the predictors of personal and perceived stigma associated with depression. Method Three samples were surveyed to investigate the predictors: a national sample of 1,001 Australian adults; a local community sample of 5,572 residents of the Australian Capital Territory and Queanbeyan aged 18 to 50 years; and a psychologically distressed subset (n = 487 of the latter sample. Personal and Perceived Stigma were measured using the two subscales of the Depression Stigma Scale. Potential predictors included demographic variables (age, gender, education, country of birth, remoteness of residence, psychological distress, awareness of Australia's national depression initiative beyondblue, depression literacy and level of exposure to depression. Not all predictors were used for all samples. Results Personal stigma was consistently higher among men, those with less education and those born overseas. It was also associated with greater current psychological distress, lower prior contact with depression, not having heard of a national awareness raising initiative, and lower depression literacy. These findings differed from those for perceived stigma except for psychological distress which was associated with both higher personal and higher perceived stigma. Remoteness of residence was not associated with either type of stigma. Conclusion The findings highlight the importance of treating the concepts of personal and perceived stigma separately in designing measures of stigma, in interpreting the pattern of findings in studies of the predictors of stigma, and in designing, interpreting the impact of and disseminating interventions for stigma.

Esta zona se encuentra en la Zona de Transición, un área biogeográficamente importante de Norteamérica caracterizada por una gran heterogeneidad ambiental local. Sin embargo, poco se conoce sobre la composición taxonómica y la organización de los mamíferos pequeños nativos y sobre la influencia de los factores ecológicos locales, en particular en tipos de vegetación diferentes. Por lo tanto, se estudió la composición de especies y la estructura de los ensambles de pequeños mamíferos de esta sierra y se proporcionó información sobre el nivel de anidamiento y la detección de patrones en su organización. El área de estudio fue el rancho "El Durangueño", Durango, México. Se muestrearon tres tipos de vegetación diferentes (pastizales y bosques de encino-pino y pino-encino por estación de 2005 y 2006. Los roedores fueron capturados, recapturados e identificados durante tres noches por sitio. Los resultados produjeron 520 individuos (386 capturas, 134 recapturas de 18 especies de mamíferos pequeños (14 ratones, cuatro ardillas de tamaños corporales diferentes, de afinidades neártica, neotropical o compartida; se encontraron endemismos y taxas en alguna categoría de riesgo de extinción. La riqueza y la equitabilidad fueron altas, la diversidad y los niveles poblacionales fueron moderados, a excepción de un bosque de encino-pino con densidad de pequeños mamíferos alta y la dominancia de alguna especie en el bosque de pino-encino, debido probablemente a perturbaciones. El patrón espacial de las especie de tamaño mediano no fue azaroso. El ensamblaje de especies no presentó anidamiento y tuvo una distribución log-normal, con cuatro especies comunes y de amplia distribución (Peromyscus truei, P. maniculatus, Reithrodontomys montanus y Sigmodon leucotis y siete de distribución restringida

They consider two ways to solve the problem: the religious dialogue that leads Turkeys to convert to Christianism and then make legitimate their conquest, for example, the short work of Nicholas of Cusa De pace fidei, and partially the Epistula ad Mahumetem of Pius II, and the foundation of a great alliance of Christian princes: vg. the paneuropean project of George Podiebrad, inspired by the old idea of crusade.

Reflexiona sobre la forma en que ambas cristiandades trataron el problema que las imágenes representan para las prácticas religiosas y las consecuencias políticas del culto de los iconos. El escrito afirma también que durante los siglos VIII y IX la crisis iconoclasta permitió la aparición de una tradición cristiana latina consciente de sí misma. Por lo tanto, se trató del momento que puso en evidencia el nacimiento de dos formas divergentes de piedad cristiana y la alienación de una respecto de la otra. La cristiandad occidental centrada en el edificio eclesiástico y que privilegiaba la ubicación de lo sagrado en el rito eucarístico, y la oriental cuyo centro era la adoración de las imágenes, con la consecuente multiplicación de los espacios sagrados.The following paper deals with the reception in the Carolingian west of the Byzantine Iconoclast Crisis. It considers the way both Christianities dealed with the problem that images presented to religious practices and the political consequences of iconic worship. The paper also states that during the VIII and IX centuries the iconoclast crisis allowed the emergence of a self conscious Latin Christian tradition. Consequently it was the moment that showed the beginning of two differing ways of Christian piety and the alienation of one towards the other. Western Christianity focused its religion practice in church building and the idea of Sacrality in the Eucharistic Rite. The oriental church, moreovers, centered its practices and theology on icon worship.

    Metallothionein-III is a low molecular weight, heavy-metal binding protein expressed mainly in the central nervous system. First identified as a growth inhibitory factor (GIF) of rat cortical neurons in vitro, it has subsequently been shown to be a member of the metallothionein (MT) gene family...... injected rats. The specificity of the antibody was also demonstrated in immunocytochemical studies by the elimination of the immunostaining by preincubation of the antibody with brain (but not liver) extracts, and by the results obtained in MT-III null mice. The antibody was used to characterize...... the putative differences between the rat brain MT isoforms, namely MT-I+II and MT-III, in the freeze lesion model of brain damage, and for developing an ELISA for MT-III suitable for brain samples.

    Full Text Available The role of the ‘charrería’ as a cultural phenomenon in the construction of the Mexican WestThis paper presents an anthropological point of  view of one aspect in the formation of the central  western region of Mexico (particularly the province of Jalisco that has traditionally acted as a  counterweight to the centralized power of the  nation and has led to interesting negotiating positions stemming from both parts. The search for  symbols that could synthesize and represent  ‘Mexicanness’ as emblems for a nascent national  identity led to an emphasis on diverse regional  elements. Nevertheless, the characteristic elements of the central western region of Mexico –  more specifically Jalisco – gradually dominated as  the typical features for a national identity over  other features offered from a countrywide pool.  Due to a variety of reasons, the central western  region of Mexico has played a key role in the formation of a nationalist discourse required to  fortify the modern Mexican State. The proposed  mode of analysis is through the study of the cultural group of ‘charros’ from the State of Jalisco,  on the basis that the idea of the figure of ‘el charro’ – imagined as originating in Jalisco – is a  reference for that which is ‘typically Mexican’,  concentrating symbolic and other functions which  define, among other aspects, internal national  boundaries. This representation has thus become the national emblem ‘par excellence’ that, nevertheless, has been mutating in its symbolic content.Resumen:Desde una perspectiva antropológica se presenta  un aspecto del proceso de conformación de la  región Occidente de México, particularmente de  Jalisco, que ha operado como tradicional instancia-contrapeso del poder central nacional, y que  ha conducido a interesantes negociaciones entre  ambas partes.

    Full Text Available La sociedad actual recibe, entre otras denominaciones, modernidad tardía o reflexiva, y sociedad del conocimiento. A fin de explicarla se acude a múltiples abordajes pero sobre todo se advierte su complejidad y su intrincado sistema de relaciones. Se han buscado respuestas a sus más grandes problemas no sólo en la sociología sino también en las variadas formas de combinar análisis sociales con análisis políticos, económicos, culturales y filosóficos. Un papel relevante y difundido juega Ulrich Beck al caracterizar la sociedad del riesgo. Para él, la segunda modernidad tiene que ver con la forma como en occidente se ha ido presentando un cambio en las ideas impulsoras que preconizaban el progreso, el control, el pleno empleo y la explotación de la naturaleza. Fenómenos como la industrialización y el mercado dentro del capitalismo, para mencionar sólo uno de los procesos más influyentes en la sociedad moderna, han desembocado en la globalización, la individualización, la revolución de géneros, el subempleo y las amenazas planetarias, las cuales van conformando su perspectiva de la sociedad del riesgo, como la denomina Beck. Hay, sin embargo, un occidente al norte y otro al sur. Esto igualmente plantea desafíos, nuevas dinámicas y preguntas sobre el mundo y la supervivencia, pero también sobre aspectos centrales para los seres humanos, entre ellos, la salud. ¿Cuáles son las razones para prestar tanta atención al riesgo y que este, a su vez, se inmiscuya en todos los planos de la sociedad? ¿Cómo enfrentar los retos que la sociedad del riesgo plantea al área asistencial? ¿Qué implicaciones tiene hablar de conocimiento, riesgo, miedo y también desconocimiento en la atención en salud? Estas son sólo algunas de las preguntas que surgen de la dinámica social actual. En esta reflexión se tendrán en cuenta las características de la sociedad del riesgo enunciadas por Beck y su relación con los análisis de expertos en

    Full Text Available El artículo pretende analizar la imagen de poder creada en Occidente alrededor de Solimán el Magní co y su esposa Roxolana. Bajo el deseo de entender la magni cencia de ambos sultanes, el escrito se ha estructurado en torno a tres aspectos fundamentales. El primero de ellos se ha centrado en la relevancia de Solimán y su imperio, para hallar la explicación de su capacidad militar y la razón de ser considerado una amenaza para el mundo occidental. Seguidamente se ha presentado el palacio como expresión arquitectónica de poder, además de ser el espacio donde se situaba el harén. Ello ha conducido a re exionar sobre el papel de la mujer en la sociedad turca y se ha profundizado en la gura de Roxolana, la favorita del Gran Turco. Así pues, se han estudiado ejemplos de las crónicas, la literatura de viajes, los libros de indumentaria, los grabados y las pinturas elaborados en nuestro continente a lo largo de los siglos xvi y xvii, puesto que la cultura escrita en comunión con las artes visuales se encargaron de crear la imagen conceptual y grá ca de los grandes gobernadores orientales. The aim of this article is to analyse the images of power surrounding Süleyman the Magni cent and his wife, Roxolana. In order to understand the sultan’s splendour the article deals with three key aspects. e rst one is the palace as an architectural ensemble which reveals the governor’s power. e harem was located there as well, which leads us to re ect the role of women in the Turkisch society, and especially the role of Roxolana, the Great Turk’s favourite. Consequently, we study the chronicles, travel literature, clothing books, engravings and paintings made in the sixteenth and seventeenth century. e writings together with the artworks created the conceptual and graphic images about Roxolana and Süleyman, thereby spreading their magni cence and power.

    Full Text Available En el mismo año en que se publicaba póstumamente el así llamado “último gran tratado moderno de la disciplina estética”, la Teoría Estética de T. W. Adorno, un joven Giorgio Agamben escribía su contribución, marginal pero decisiva, a un debate muy presente en la filosofía italiana por esos días. Se trata del debate en torno a las relaciones entre el destino nihilista de la metafísica occidental, la estética y la política del que se ocupan entre otros el “pensiero debole” de Gianni Vattimo y el “pensiero negativo” de Massimo Cacciari. Este trabajo tiene como objetivo general analizar las tesis del primer libro de Agamben, L’uomo senza contenuto, en cuanto intento por comprender el proyecto estético de Occidente. Allí se afirma que el ingreso del arte en la dimensión estética con la Modernidad responde al desplazamiento de una consideración de la capacidad pro-ductiva humana (la “inquietante” téchne que permite al hombre llevar una cosa del no-ser al ser hacia una mirada centrada en el punto de vista del espectador que puede apreciar “desinteresadamente” la belleza. Pero este proceso, lejos de ser natural, evidencia una crisis del “hacer” humano en general. Si con Aristóteles podía distinguirse entre póiesis (un hacer aparecer o un traer a la presencia como forma de un saber y praxis (un realizar producto de la voluntad, entendida como apetito, como forma de un actuar, en la Modernidad asistimos al solapamiento de la esfera poiética por la de la praxis y a una progresiva reducción de toda actividad productiva al trabajo que, por reducir al hombre a su desnuda vida biológica, es la dimensión más baja de la vida activa. Teniendo en cuenta este diagnóstico agambeniano, me propongo pensar aquí el lugar central que tendría la estética como disciplina filosófica privilegiada para preguntar por las posibilidades actuales de una nueva póiesis y con ella de una “vita nova” para el hombre.

    1985-07-01

    This is the third in the series of reports covering the Fusion Power Demonstration (FPD) design study. This volume considers the FPD-III configuration that incorporates an octopole end plug. As compared with the quadrupole end-plugged designs of FPD-I and FPD-II, this octopole configuration reduces the number of end cell magnets and shortens the minimum ignition length of the central cell. The end-cell plasma length is also reduced, which in turn reduces the size and cost of the end cell magnets and shielding. As a contiuation in the series of documents covering the FPD, this report does not stand alone as a design description of FPD-III. Design details of FPD-III subsystems that do not differ significantly from those of the FPD-II configuration are not duplicated in this report

Estos encuentros se caracterizan por una revalorización política de lo psíquico, lo singular y lo subjetivo, la cual, en los orígenes de la revolución cultural occidental de la segunda mitad del siglo XX , resulta precursora de l auge de los factor es personal es y micropolítico s en el feminismo, los movimientos juveniles , el combate por la emancipación sexual y otras luchas de las décadas de 1960 y 1970. Se abordan las revisiones freudianas del marxismo en Henri De Man y Max Eastman, la reapropiación marxista de tales revisiones en Antonio Gramsci, José Carlos Mariátegui y Alfonso Teja Zabre, y las propuestas freudomarxistas de Siegfried Bernfeld, Wilhelm Reich y Otto Fenichel.

    Full Text Available La investigación caracterizó el sentido de compromiso en la atención del cliente interno de la gerencia de servicios logísticos en PDVSA Occidente. Se fundamentó el trabajo en Kinsey (2001, Robbins (2001; 2002, Cottle (2005, entre otros. El diseño fue no experimental, transeccional, descriptivo. La población estuvo conformada por 17 directivos de la gerencia en estudio. La data se colectó por medio del instrumento SECOMAC.2008, con una confiabilidad de 0.94 determinada por medio del coeficiente Alfa Cronbach. El resultado global fue alto en sentido del compromiso; sin embargo, dentro de la aparente fortaleza del mismo se encontraron en algunos indicadores fallas específicas que requirieron un análisis más detallado. Se concluyó que indicadores como entusiasmo, empatía y capacidad de respuestas no están del todo definidos en su buen desarrollo y aplicación, mientras que la fiabilidad y metas individuales en el cargo como indicador del compromiso con la gerencia están en condiciones deficientes. Todo ello permite deducir que el cliente interno es todos y cada uno de los integrantes de la empresa, a los cuales es necesario vender primero, el valor del producto o servicio que la organización ofrece y la importancia fundamental que él tiene como representante de la misma.

    Full Text Available Research on ancient mercenaries is fraught with problems, being the match between the scarce and partial data provided by the literary sources and the archaeological record a tricky and difficult matter. The recent publication of two books dealing with Iberian and Celtic mercenaries, by Raimon Graells and Luc Baray respectively, offers us an opportunity to dwell on a pervading discussion when studying cultural and military dynamics, and long distance relationships in Ancient Western Europe.La actividad mercenaria en la Antigüedad es uno de los campos de estudio más complejos de la investigación histórica, en buena medida debido a la difícil combinación que existe entre los siempre parciales datos de las fuentes literarias y la arqueología. La reciente publicación de dos monografías dedicadas al mercenario ibérico y celta, a cargo respectivamente de Raimon Graells y Luc Baray, nos brinda una magnífica oportunidad para retomar una vieja discusión siempre latente en el estudio de las dinámicas bélicas y culturales, y que nos permite ahondar en las intrincadas relaciones a larga distancia en el Occidente europeo antiguo.

El objeto de este trabajo es hacer un análisis a través de la historia de la dilución de los saberes de las mujeres respecto a la salud y el conocimiento de su propio cuerpo, como una herencia de la Práctica Médica occidental. La información se obtuvo de bibliografía especializada en el tema, elaborándose con ella un análisis a partir del enfoque de género y salud, con el cual se muestra cómo desde la belladona hasta la partera, los conocimientos de las mujeres se siguen considerando marginales en el marco de la medicina hegemónica. Most women in underdeveloped countries search for their health without autonomy. The object of this work is to analyze through history the dilution of women’s knowledge about health and knowledge of their own body, as a legacy from the Western Medical Practice. The information is based on specialized literature, thus elaborating an analysis by the focus on gender and health, which shows how from the belladonna to the midwife, women’s knowledge is still considered marginal in the framework of the hegemonic medicine.

    Worldwide, Facebook is becoming increasingly widespread as a communication platform. Young people especially use this social networking site daily to maintain and establish relationships. Despite the Facebook expansion in the last few years and the widespread acceptance of this social network, research into Facebook Addiction (FA) is still in its infancy. Hence, the potential predictors of Facebook overuse represent an important matter for investigation. This study aimed to deepen the understanding of the relationship between personality traits, social and emotional loneliness, life satisfaction, and Facebook addiction. A total of 755 participants (80.3% female; n = 606) aged between 18 and 40 (mean = 25.17; SD = 4.18) completed the questionnaire packet including the Bergen Facebook Addiction Scale, the Big Five, the short version of Social and Emotional Loneliness Scale for Adults, and the Satisfaction with Life Scale. A regression analysis was used with personality traits, social, family, romantic loneliness, and life satisfaction as independent variables to explain variance in Facebook addiction. The findings showed that Conscientiousness, Extraversion, Neuroticism, and Loneliness (Social, Family, and Romantic) were strong significant predictors of FA. Age, Openness, Agreeableness, and Life Satisfaction, although FA-related variables, were not significant in predicting Facebook overuse. The risk profile of this peculiar behavioral addiction is also discussed.

    The growing power demand of users, who make loads of power systems, causes the components of such systems operating near its operating limits. And the transmission line, being the most common component in these, requires a thorough analysis in regard to the probability of three-phase shots and monopolars reclosing, considering thunderstorms, the demand system time, the flows circulating in lines, maintenance on other lines and other imponderantes. This research analyzes the normal probability of occurrence of shots in the 400 kV core network of the Area de Control Occidental, CFE and its impact on studies conducted prior to the maintenance. We intend to use the methodology in the Comision Federal de Electricidad and results can be validated with data from previous years, based on a pseudo shots forecast in a given period. [Spanish] La creciente demanda de energia electrica de los usuarios que componen las cargas de los sistemas electricos de potencia, provoca que los componentes de dichos sistemas funcionen cerca de sus limites operativos. Y la linea de transmision, al ser el componente mas comun en estos, requiere de un analisis minucioso en lo que respecta a la probabilidad de disparos trifasicos y recierres monopolares, considerando tormentas electricas, la demanda horaria del sistema, los flujos que circulan en las lineas, los mantenimientos en las demas lineas y demas imponderantes. En esta investigacion se analiza la probabilidad normal de ocurrencia de disparos en la red troncal de 400 kV del Area de Control Occidental y su impacto en los estudios que se realizan previos a los mantenimientos. Se pretende utilizar la metodologia en la Comision Federal de Electricidad, y los resultados pueden ser validados con datos de los anos anteriores, ya que se hace un pseudo pronostico de disparos en un periodo dado.

    The eastern part of the Cordillera Occidental of Ecuador comprises thick buoyant oceanic plateaus associated with island-arc tholeiites and subduction-related calc-alkaline series, accreted to the Ecuadorian Continental Margin from Late Cretaceous to Eocene times. One of these plateau sequences, the Guaranda Oceanic Plateau is considered as remnant of the Caribbean-Colombian Oceanic Province (CCOP) accreted to the Ecuadorian Margin in the Maastrichtien. Samples studied in this paper were taken from four cross-sections through two arc-sequences in the northern part of the Cordillera Occidental of Ecuador, dated as (Río Cala) or ascribed to (Macuchi) the Late Cretaceous and one arc-like sequence in the Chogòn-Colonche Cordillera (Las Orquídeas). These three island-arcs can clearly be identified and rest conformably on the CCOP. In all four localities, basalts with abundant large clinopyroxene phenocrysts can be found, mimicking a picritic or ankaramitic facies. This mineralogical particularity, although not uncommon in island arc lavas, hints at a contribution of the CCOP in the genesis of these island arc rocks. The complete petrological and geochemical study of these rocks reveals that some have a primitive island-arc nature (MgO values range from 6 to 11 wt.%). Studied samples display marked Nb, Ta and Ti negative anomalies relative to the adjacent elements in the spidergrams characteristic of subduction-related magmatism. These rocks are LREE-enriched and their clinopyroxenes show a tholeiitic affinity (FeO T-TiO 2 enrichment and CaO depletion from core to rim within a single crystal). The four sampled cross-sections through the island-arc sequences display homogeneous initial Nd, and Pb isotope ratios that suggest a unique mantellic source for these rocks resulting from the mixing of three components: an East-Pacific MORB end-member, an enriched pelagic sediment component, and a HIMU component carried by the CCOP. Indeed, the ankaramite and Mg

    Full Text Available RESUMEN A lo largo del siglo XX la influencia de Japón en la arquitectura occidental ha tenido momentos destacados. Alison y Peter Smithson estudiaron las miradas al mundo japonés de las generaciones precedentes de arquitectos y subrayaron nuevos aspectos a considerar en él, relacionados con la estética de lo desechable y la cultura pop. La vivienda japonesa inspiró conceptualmente algunas de sus utopías domésticas, que influirían de manera especial en el grupo británico Archigram y, a través de ellos, en otros grupos radicales de los años sesenta. Los Smithson jugaron también un papel clave en la disolución de los CIAM en 1959 y en la creación del Team X. En ese último CIAM, participó Kenzo Tange presentando varios proyectos japoneses vanguardistas, dando comienzo a un rico periodo de intercambio de ideas entre occidente y Japón, que continuaría en la World Design Conference de Tokio, en 1960, y en posteriores encuentros del Team X . En el presente escrito la pareja británica sirve de hilo conductor, por su papel activo y crítico en todos estos encuentros. El artículo analiza esos momentos de conexión para establecer influencias mutuas, críticas, paralelismos y divergencias entre la arquitectura europea, personalizada en los Smithson, Archigram y el Team X, y los Metabolistas Japoneses a través de diversas escalas del diseño, desde lo doméstico a lo urbano.

    Full Text Available OBJECTIVES: West Nile virus (Flavivirus: Flaviviridae; WNV has spread rapidly throughout the Caribbean Basin since its initial detection there in 2001. This report summarizes our current knowledge of WNV transmission in tropical America. METHODS: We reviewed the published literature and consulted with key public health officials to obtain unpublished data. RESULTS: West Nile virus infections first appeared in human residents of the Cayman Islands and the Florida Keys in 2001, and in apparently healthy Jamaican birds sampled early in 2002. Serologic evidence of WNV infection in 2002 was detected in horses, chickens and resident free-ranging birds in Guadeloupe, the Dominican Republic, and eastern Mexico. In 2003, WNV spread in Mexico and northern Central America, and serologic evidence was detected in the Bahamas, Puerto Rico and Cuba. In 2004, the first serologic evidence of WNV activity in South American ecosystems surfaced in September-October in Colombia and Trinidad, where domestic animals circulated WNV-neutralizing antibodies. CONCLUSIONS: The sparse reports of equine, human and avian disease in Latin America and the Caribbean is puzzling. Isolates are needed to evaluate viral attenuation or other possible explanations for reduced disease burden in tropical ecosystems.OBJETIVOS: El virus del Nilo occidental (VNO, familia Flaviviridae, género Flavivirus se ha propagado rápidamente por toda la cuenca del Caribe desde que se detectó por primera vez en 2001.

    Accurate assessments of recurrence risk and absolute treatment benefit are needed to inform colon cancer adjuvant therapy. The 12-gene Recurrence Score assay has been validated in patients with stage II colon cancer from the Cancer and Leukemia Group B 9581 and Quick and Simple and Reliable (QUASAR) trials. We conducted an independent, prospectively designed clinical validation study of Recurrence Score, with prespecified end points and analysis plan, in archival specimens from patients with stage II and III colon cancer randomly assigned to fluorouracil (FU) or FU plus oxaliplatin in National Surgical Adjuvant Breast and Bowel Project C-07. Recurrence Score was assessed in 892 fixed, paraffin-embedded tumor specimens (randomly selected 50% of patients with tissue). Data were analyzed by Cox regression adjusting for stage and treatment. Continuous Recurrence Score predicted recurrence (hazard ratio for a 25-unit increase in score, 1.96; 95% CI, 1.50 to 2.55; P < .001), as well as disease-free and overall survival (both P < .001). Recurrence Score predicted recurrence risk (P = .001) after adjustment for stage, mismatch repair, nodes examined, grade, and treatment. Recurrence Score did not have significant interaction with stage (P = .90) or age (P = .76). Relative benefit of oxaliplatin was similar across the range of Recurrence Score (interaction P = .48); accordingly, absolute benefit of oxaliplatin increased with higher scores, most notably in patients with stage II and IIIA/B disease. The 12-gene Recurrence Score predicts recurrence risk in stage II and stage III colon cancer and provides additional information beyond conventional clinical and pathologic factors. Incorporating Recurrence Score into the clinical context may better inform adjuvant therapy decisions in stage III as well as stage II colon cancer.

    Disability retirement may increase as the work force ages, but there is little information on factors associated with retirement because of disability. This is the first prospective population-based study of predictors of disability retirement including information on workplace, socioeconomic, behavioral, and health-related factors. The subjects were 1038 Finnish men who were enrolled in the Kuopio Ischemic Heart Disease Risk Factor Study, who were 42, 48, 54, or 60 years of age at the beginning of the study, and who participated in a 4-year follow-up medical examination. Various job characteristics predicted disability retirement. Heavy work, work in uncomfortable positions, long workhours, noise at work, physical job strain, musculoskeletal strain, repetitive or continuous muscle strain, mental job strain, and job dissatisfaction were all significantly associated with the incidence of disability retirement. The ability to communicate with fellow workers and social support from supervisors tended to reduce the risk of disability retirement. The relationships persisted after control for socioeconomic factors, prevalent disease, and health behavior, which were also associated with disability retirement. The strong associations found between workplace factors and the incidence of disability retirement link the problem of disability retirement to the problem of poor work conditions.

    Difficult laryngoscopy in pediatric patients undergoing anesthesia. This retrospective analysis was conducted to investigate incidence and predictors of difficult laryngoscopy in a large cohort of pediatric patients receiving general anesthesia with endotracheal intubation. Young age and craniofacial dysmorphy are predictors for the difficult pediatric airway and difficult laryngoscopy. For difficult laryngoscopy, other general predictors are not yet described. Retrospectively, from a 5-year period, data from 11.219 general anesthesia procedures in pediatric patients with endotracheal intubation using age-adapted Macintosh blades in a single center (university hospital) were analyzed statistically. The overall incidence of difficult laryngoscopy [Cormack and Lehane (CML) grade III and IV] was 1.35%. In patients younger than 1 year, the incidence of CML III or IV was significantly higher than in the older patients (4.7% vs 0.7%). ASA Physical Status III and IV, a higher Mallampati Score (III and IV) and a low BMI were all associated (P pediatric anesthesia is lower than in adults. Our results show that the risk of difficult laryngoscopy is much higher in patients below 1 year of age, in underweight patients and in ASA III and IV patients. The underlying disease might also contribute to the risk. If the Mallampati score could be obtained, prediction of difficult laryngoscopy seems to be reliable. Our data support the existing recommendations for a specialized anesthesiological team to provide safe anesthesia for infants and neonates. © 2012 Blackwell Publishing Ltd.

Mining is now coming back into its own due to Rio Narcea Gold Mines, whose intense digging brought up nearly three tons of gold in the year 2000, fundamentally in the towns of Belmonte and Salas. In addition to mining panning for gold is being revived as a source of the precious metal and a tourist attraction for the Navelgas area of the town of Tineo.

    [es] El noroeste español, y concretamente el occidente asturiano, cuenta con una amplia tradición en la explotación aurífera que es anterior a la conquista romana y que ha perdurado con altibajos hasta nuestros días. Actualmente, esta explotación está adquiriendo notable importancia por la intensa actividad extractiva llevada a cabo por la empresa Rio Narcea Gold Mines, fundamentalmente en los municipios de Belmonte y Salas, que le permitió obtener casi tres toneladas de oro en el año 2000. A esta actividad minera hay que añadir la recuperación del bateo como fuente para obtener oro y atraer turistas hacia el entorno de Navelgas (Tineo. [fr] Dans la région nord-ouest de l'Espagne, et plus précisément dans la partie occidentale des Asturias, il existe une longue tradition dans le domaine de l'exploitation aurifère, qui remonte à une époque antérieure à la conquête romaine et qui a perduré, avec des hauts et des bas, jusqu'à nos jours. A l'heure actuelle, cette exploitation est en train de devenir de plus en plus importante grâce à l'intense activité extractive exercée par l'entrepise Rio Narcea Gold Mines sur les communes de Belmonte et Salas, essentiellement, activité qui lui a permis d'obtenir près de trois tonnes d'or en l'an 2000.

    Full Text Available A fines de la década del '80, se ha producido en nuestro país un sostenido desarrollo de los estudios bioarqueológicos orientados a obtener información relevante para discutir diversos aspectos del proceso evolutivo y adaptativo de las poblaciones prehistóricas. Los proyectos realizados y aquellos en desarrollo, presentan un marcado énfasis regional y consideran una amplia gama de indicadores biológicos referidos a aspectos tales como las pautas de salud, nutrición, dieta y actividad de poblaciones correspondientes a distintos períodos del Holoceno. En la Región Pampeana, los trabajos bioarqueológicos llevados a cabo hasta el presente, son escasas las consideraciones sobre el sector comprendido por el Borde Occidental de la Provincia de Buenos, e inexistentes en el Sur de la Provincia de Santa Fe. El presente trabajo está orientado a analizar desde una perspectiva Bioarqueológica, la interrelación entre los procesos bioculturales y paleoambientales en distintos ambientes ecotonales de la Pampa Húmeda. Específicamente se halla abocado al análisis comparativo de sectores con características ecológicas diferentes, ya que se trata de áreas de transición, factor que probablemente influyó en la toma de decisiones por parte de los grupos humanos que habitaron la región a través del tiempo. El objetivo general es estudiar la variabilidad en los modos de uso del espacio y adaptación biocultural por parte de los pobladores de ambientes ecotonales pampeanos. La particularidad ambiental del área de estudio y la variedad del registro bioarqueológico, permiten suponer que la información generada de este modo contribuirá a aumentar y complejizar el conocimiento acerca de los procesos que estructuran el registro arqueológico a distintas escalas espaciales y temporales como un paso necesario para la comprensión de la evolución y adaptación de las poblaciones humanas.

    Full Text Available Las evidencias observacionales indican que durante las últimas décadas el clima de Cuba se ha hecho más cálido, se ha observado un incremento de los totales de precipitación en el período poco lluvioso y un cierto decrecimiento en el período lluvioso, y la frecuencia de sequías se ha incrementado significativamente desde 1960. El objetivo de este trabajo fue determinar, en las marchas anuales de la temperatura del aire de cada estación meteorológica en la zona más occidental de Cuba, las fechas del paso de la temperatura media del aire por encima y por debajo de 25°C y la duración de esos períodos, enmarcar los períodos lluvioso y poco lluvioso, y obtener su relación con la fecha del paso de la temperatura media del aire por el umbral señalado. Se comprobó que las regularidades encontradas en las relaciones "paso de la temperatura por encima de 25°C - inicio del período lluvioso" y "paso de la temperatura por debajo de 25°C - inicio del período poco lluvioso" durante el período de referencia 1950-1975 ya no constituyen regularidades en el período de referencia 1976-2005, principalmente en el período en que la temperatura media del aire pasa por debajo de los 25°C, donde los desaciertos alcanzaron las mayores desviaciones. La duración media del período con temperaturas superiores a 25°C muestra una tendencia al aumento, obteniéndose una longitud mayor durante este período que la observada en el período con temperaturas inferiores a 25°C.

    Full Text Available La familia Heliconiaceae tiene un solo género, Heliconia L., con aproximadamente 250 especies. Debido al colorido de sus brácteas son muy usadas para fines ornamentales presentando una creciente comercialización en el mercado internacional, lo que ha incentivado el aumento en el área productiva en los países de Centro y Sur América, al proporcionar una mayor oferta y demanda del producto. Sin embargo, existe en este género, confusión sobre el número de especies y las relaciones entre ellas. Esta inapropiada nomenclatura, puede originar problemas a nivel comercial y científico. En esta investigación realizada durante el 2014, se caracterizaron genéticamente 44 individuos del género Heliconia de importancia comercial en el centro occidente de Colombia, que corresponden a 4 especies, y un híbrido interespecífico, por medio de la amplificación de marcadores microsatélites previamente desarrollados para Heliconia bihai y Heliconia caribaea y marcadores microsatélites propios obtenidos del desarrollo de una librería genómica enriquecida con microsatélites para Heliconia orthotricha. Se seleccionaron 18 marcadores para realizar las caracterizaciones. Se utilizaron las estrategias de amplificación directa, así como la transferibilidad de marcadores. El equilibrio Hardy-Weinberg (EHW se rompió para algunos de los marcadores empleados en las diferentes especies de este estudio, ya que pertenecían a cultivares comerciales con alta presión de selección por parte de los cultivadores. El marcador Hb_C115 presentó el ligamiento con un mayor número de marcadores. Muchos de los marcadores están ligados entre sí y al no poseer mapas de ligamiento para ninguna especie del género no es posible determinar la cercanía de los mismos en los cromosomas. Se confirma la transferibilidad de los microsatélites desarrollados para diferentes especies del género Heliconia, como una herramienta útil en la caracterización varietal, la cual

    Full Text Available Mucho se ha escrito sobre la aportación de la Partida Doble al desarrollo económico de Occidente. El presente trabajo pretende presentar un análisis detallado del papel que desempeñó la contabilidad en la génesis del capitalismo. La contabilidad, como herramienta de gestión, fue un factor clave en la organización comercial.Después de ofrecer una visión panorámica de la organización del comercio en la época medieval y de considerar varias acepciones del concepto de partida doble, el estudio concluye que ésta fue al mismo tiempo causa y efecto de la transición de los mercaderes itinerantes a sedentarios.La expansión del comercio y del número de inversiones en las que un mercader podía estar inmerso a un mismo tiempo creó la necesidad de una integración y un ordenamiento que, en cierto modo, la Partida Doble exigía y propagaba. Un comercio más amplio demandaba un sistema gerencial mejor. Ese buen sistema gerencial –la partida doble-, fue un factor decisivo en el incremento comercial.Thousands of pages have been written about the double-entry contribution to the economic development of the Western world. The present paper tries to present a detailed analysis on the role played by Accounting in the genesis of capitalism. Accounting, as a management tool, was a key factor in the commercial organization.After having offered a general view about the organization of commerce in the Medieval era, some double-entry concepts are dealt with. The study concludes that double-entry was at the same time cause and effect of the transition from travelling merchants to resident ones.The expansion of commerce and the number of investments a merchant could be involved in at a time created the need of an integration and an order that, to certain extent, double-entry implied and spread. A bigger commerce demanded a better management system. This managerial system –the double-entry-, was a conclusive factor in the commercial growth.

  13. Distillation Column Flooding Predictor

    Energy Technology Data Exchange (ETDEWEB)

    George E. Dzyacky

    2010-11-23

    The Flooding Predictor™ is a patented advanced control technology proven in research at the Separations Research Program, University of Texas at Austin, to increase distillation column throughput by over 6%, while also increasing energy efficiency by 10%. The research was conducted under a U. S. Department of Energy Cooperative Agreement awarded to George Dzyacky of 2ndpoint, LLC. The Flooding Predictor™ works by detecting the incipient flood point and controlling the column closer to its actual hydraulic limit than historical practices have allowed. Further, the technology uses existing column instrumentation, meaning no additional refining infrastructure is required. Refiners often push distillation columns to maximize throughput, improve separation, or simply to achieve day-to-day optimization. Attempting to achieve such operating objectives is a tricky undertaking that can result in flooding. Operators and advanced control strategies alike rely on the conventional use of delta-pressure instrumentation to approximate the column’s approach to flood. But column delta-pressure is more an inference of the column’s approach to flood than it is an actual measurement of it. As a consequence, delta pressure limits are established conservatively in order to operate in a regime where the column is never expected to flood. As a result, there is much “left on the table” when operating in such a regime, i.e. the capacity difference between controlling the column to an upper delta-pressure limit and controlling it to the actual hydraulic limit. The Flooding Predictor™, an innovative pattern recognition technology, controls columns at their actual hydraulic limit, which research shows leads to a throughput increase of over 6%. Controlling closer to the hydraulic limit also permits operation in a sweet spot of increased energy-efficiency. In this region of increased column loading, the Flooding Predictor is able to exploit the benefits of higher liquid

    Neil Brenner

    2003-05-01

    Full Text Available Este artículo examina la cambiante relación entre las ciudades globales y los Estados nacionales en la Europa Occidental post ‘70. La mayoría de los enfoques sobre la formación de ciudades globales están basadas en una concepción de suma-cero respecto de la escala espacial, lo que conduce a enfatizar el declive del poder de los Estados nacionales: mientras que la escala global se expande, se plantea que la escala nacional se contrae. En contraste, en este artículo la globalización se concibe como una reconfiguración contradictoria de las escalas espaciales, incluyendo aquellas en las que los Estados nacionales están organizados. Desde este punto de vista, los Estados nacionales no están siendo erosionados bajo las condiciones geoeconómicas contemporáneas, sino rearticulados, re-territorializados y re-escalados. La resultante configuración re-escalada de la espacialidad del Estado es provisionalmente denominada como una forma estatal "glocalizada". Como nodos de acumulación de capital, las ciudades globales son sitios claves de formas post-fordistas de desarrollo industrial. Como coordenadas del poder territorial estatal, las ciudades globales son niveles locales y/o regionales dentro de matrices glocalizadas y re-territorializadas de organización espacial del Estado. El re-escalamiento del Estado ha venido así a servir como una importante estrategia de acumulación a través de las cuales estas instituciones del Estado transformadas están tratando de promover la competitividad territorial de sus principales regiones urbanas. Estos argumentos son ilustrados a través de una discusión general de la interfase entre las ciudades globales y los Estados nacionales en la Europa Occidental contemporánea. La sección final sugiere que se requieren nuevas teorías y representaciones sobre la escala geográfica y del espacio del Estado, en orden a dar cuenta de la rápidamente cambiante geografía económica y política de los inicios

    Full Text Available Why do anthropology and history seem to be two completely autonomous disciplines? When did they split up? Do they keep talking? –at least in order to raise their common offspring… Three will be my points. Firstly, as anthropology is a “logos” about “anthropos”, history is not possible without some anthropology. I think that a short tour through the history of Western thought, from Ancient Greece to Enlightenment, will show it clearly. Secondly, we will analyze how history and anthropology approached the issue of social change in the 19th century, how they became autonomous academic disciplines by the end of the century, and cut off in the interwar period, by the 1920s and 1930s. But “underground” contact was kept, waiting for more favourable circumstances. Third, I think that historians should try to understand that anthropology that always underlies on the writings of those who taught us our job. We will look for examples in two historiographical traditions: the French “Ecole des Annales” and the British “Group of Cambridge” of the 1950s.¿Por qué constituyen antropología e historia dos disciplinas separadas, de cuándo data esa separación, cuál es el grado de permeabilidad que se registra entre ambas? Estas son las preguntas que intentaré responder en este artículo. Centraré mi argumentación en tres cuestiones. La primera, que dado que la antropología es un “logos” acerca del “anthropos”, podemos argumentar que no puede existir historia carente de antropología: es lo que intentaremos mostrar en un breve recorrido por la historia del pensamiento occidental, desde la Grecia Clásica a la Ilustración. A continuación analizaremos cómo antropología e historia se enfrentaron al problema del cambio social en el siglo XIX, se diferenciaron como disciplinas académicas a finales de siglo y parecieron “cortar amarras” en el periodo de entreguerras, en las décadas de 1920 y 1930. Pero, aún en esas dif

Establecimos cuatro parcelas de 60x48 m con diferencias altitudinales de 100 m entre sí. En cada una seleccionamos aleatoriamente diez círculos de 100 m² cada uno, en los cuales medimos los diámetros normales y las alturas de las especies leñosas con diámetro 2.5 cm. Para cada especie y por parcela determinamos el área basal, la densidad, la frecuencia, la riqueza de especies y los valores de importancia. Establecimos la estructura vertical y diamétrica de N. rudis. Hicimos una ordenación directa con la matriz de especies y las variables edáficas y ambientales. El registro de N. rudis en la Sierra de Manantlán representa el primer registro para el occidente de México y el más septentrional del taxon. La población se estructura en cinco categorías diamétricas y genera una curva en forma de "J" invertida. La riqueza de especies en las parcelas donde se encuentra N. rudis, varía de 27 a 39, y los mayores valores de importancia son para Urera verrucosa, N. rudis y Ficus sp. La ordenación directa permite postular a la presencia de árboles caídos, la cobertura, la profundidad del horizonte superficial y el magnesio soluble, como los factores ambientales de mayor influencia en la distribución y abundancia de N. rudis.Population structure and environmental relationships of the tropical tree Nectandra rudis (Lauraceae, a rare species in western Mexico.

    2015-01-01

    The quest for the missing mass of the universe has become one of the big challenges of todays particle physics and cosmology. Astronomical observations show that only 1% of the matter of the Universe is luminous. Moreover there is now convincing evidence that 85% of all gravitationally observable matter in the Universe is of a new exotic kind, different from the 'ordinary' matter surrounding us. In a series of three lectures we discuss past, recent and future efforts made world- wide to detect and/or decipher the nature of Dark Matter. In Lecture I we review our present knowledge of the Dark Matter content of the Universe and how experimenters search for it's candidates; In Lecture II we discuss so-called 'direct detection' techniques which allow to search for scattering of galactic dark matter particles with detectors in deep-underground laboratories; we discuss the interpretation of experimental results and the challenges posed by different backgrounds; In Lecture III we take a look at the 'indirect detection' of the annihilation of dark matter candidates in astrophysical objects, such as our sun or the center of the Milky Way; In addition we will have a look at efforts to produce Dark Matter particles directly at accelerators and we shall close with a look at alternative nonparticle searches and future prospects.

The analysed complexes have the following colours: violet for Nd(III), white for Gd(III) and cream for Ho(III) compounds. The carboxylate groups bind as bidentate chelating (Ho) or bridging ligands (Nd, Gd). On heating to 1173K in air the complexes decompose in several steps. At first, they dehydrate in one step to form anhydrous salts, that next decompose to the oxides of respective metals. The gaseous products of their thermal decomposition in nitrogen were also determined and the magnetic susceptibilities were measured over the temperature range of 76-303K and the magnetic moments were calculated. The results show that 4-chlorophenoxyacetates of Nd(III), Gd(III) and Ho(III) are high-spin complexes with weak ligand fields. The solubility value in water at 293K for analysed 4-chlorophenoxyacetates is in the order of 10 -4 mol/dm 3 . (author)

    It describes the petrographic and metallogenic study of the oriental side of Tichka mountain (Occidental High Atlas, Morocco) which is the center of an anticlinal system, strongly folded, and approximately SW-NE oriented. The main object of this study is the description of its metallogenic activity and in particular the large variety of paragenesis which have been observed in the oriental part of Tichka mountain where the metamorphism is intense. This area presents a large abundance and diversity of deposits. The structural aspect of the oriental part of the Tichka mountain is described. The petrographic study of the complex structure of the oriental border, in particular the studies of the leucocratic complex of veins and apophyses and of the schistous and calcareous metamorphic complex, leads to make assumptions on the relationship between terminal phase of the metamorphism and the hypo-thermal paragenesis. The abundance of facies and the intensity of metamorphism also give the possibility to establish relationships between the different minerals deposits. The metallogenic study shows that mineralization are all peripheral on the Tichka mountain and increase with the number and size of the apophysis which is observed on the east side. The various hypo-thermal paragenesis are studied in the same order of the associated apophysis. The peripheral meso-thermal deposits of the north area are briefly described to complete the metallogenic aspects of the oriental border of the Tichka mountain. This study shows the nature of the two main factors which originate different types of paragenesis: one is the intrusion deep of the mineralizer, the second is the physical and chemical nature of the medium where the paragenesis occurred.

El objetivo del estudio fue contribuir al conocimiento de la flora de bosques de abeto (Abies guatemalensis, para esto se hizo el levantamiento florístico en bosques de abeto del occidente de Guatemala. Se encontraron 119 especies, 92 géneros, 50 familias en cuatro divisiones. Las familias más numerosas fueron: Asteraceae, Poaceae, Rosaceae, Lamiaceae, Apiaceae y Solanaceae y los géneros más abundantes Salvia, Alchemilla y Bidens. Las especies se ubicaron en cuatro estratos, 33 en el herbáceo inferior, 49 en el herbáceo superior, 30 en arbustos y siete en árboles. Se hace énfasis en la contribución del estudio al conocimiento de la flora de bosques de A. guatemalensis y la necesidad de otros similares en los demás bosques de esta especie, que sirva para fomentar su conocimiento y conservación. Se consideraron seis grupos de distribución geográfica, el principal es del centro de México a Centroamérica con 67% de especies. Se realiza una comparación fitogeográfica y de composición florística, con otras áreas de Abies de Guatemala y México. Se propone que a pesar de haber familias y géneros comunes, que proporcionan la estructura general entre los bosques de abeto, se deben considerar las particularidades florísticas de cada área, en el manejo y conservación influidas por suelo, latitud y microclima.The fragments of Abies guatemalensis forests in Western Guatemala are the reservoirs of plant species that have been poorly documented, missing the opportunity to expand the knowledge of the local flora and its use in conservation planning.

    Full Text Available Morphological and anatomical leaf studies were made in 32 populations belonging to 17 taxa of the genus Androcymbium in Southwest Africa. The morphological characters studied were corm and tunic characteristics, and number, distribution, shape, size, section, and color of leaves and bracts. The micromorphological characters were the leaf indument on both surface and margin, shape and size of epidermic cells, type and amount of stomata. Finally, the anatomical characters were mesophyll cell types, epidermic cell sizes, cellular wall types, size of central epidermic cells related to the other epidermic cells, and amount of idioblasts. The results showed a great heterogeneity in almost all characters analyzed. However, macromorphological characteristics related to color and shape of leaves and bracts in the genus Androcymbium could be used as indicators of taxonomic affinities among species. Conversely, the micromorphological and anatomical characteristics studied showed a great variation of types that does not agree with the interspecific relationships established from morphological, allozymatic or cpDNA RFLP data in other research carried out within the genus.

Con el propósito de controlar estas especies improductivas y aumentar la oferta forrajera en dichas áreas, se utilizan comúnmente prácticas agronómicas como por ejemplo el rolado, que generalmente es acompañado por siembra de pasturas y/o fuego prescrito. Nuestro objetivo fue evaluar el efecto de estas prácticas sobre algunos indicadores de calidad de suelo, tales como densidad aparente, carbono orgánico total, carbono orgánico particulado, respiración edáfica, carbono de la biomasa microbiana, actividad deshidrogenasa, en tres sitios característicos de la región: Alto, Media Loma y Bajo. Los tratamientos aplicados fueron rolado, rolado con siembra de Panicum maximum cv. trichoglume cv green panic, y rolado seguido por fuego prescrito. La densidad aparente, el carbono orgánico total, el carbono orgánico particulado y el carbono de la biomasa microbiana no fueron alterados por los tratamientos. Una mayor actividad deshidrogenasa se observó en el sitio Bajo, independientemente de los tratamientos y probablemente debido a un mayor contenido de agua del suelo. La respiración edáfica aumentó en el sitio Alto en todos los tratamientos, probablemente debido a la modificación de la actividad microbiana del suelo, atribuible al estímulo producido por los exudados radiculares del green panic y de las herbáceas nativas que aparecieron después de los tratamientos. En general, los indicadores de calidad de suelo no fueron afectados significativamente por los tratamientos usados, hecho atribuible a la baja intensidad de aplicación del rolado y de las prácticas asociadas (siembra de pasturas y fuegos prescriptos.

    All the 50 years of conscious pondering did not bring me nearer to an answer to the question `what is light quanta?'. Nowadays, every rascal believes, he knows it, however, he is mistaken. (A Einstein, 1951 in a letter to M Besso) Quantum optics has played a key role in physics in the last several decades. On the other hand, in these early decades of the information age, the flow of information is becoming more and more central to our daily life. Thus, the related fields of quantum information theory as well as Bose-Einstein condensation have acquired tremendous importance in the last couple of decades. In Quantum Optics III, a fusion of these fields appears in a natural way. Quantum Optics III was held in Pucón, Chile, in 27-30 of November, 2006. This beautiful location in the south of Chile is near the lake Villarrica and below the snow covered volcano of the same name. This fantastic environment contributed to a relaxed atmosphere, suitable for informal discussion and for the students to have a chance to meet the key figures in the field. The previous Quantum Optics conferences took place in Santiago, Chile (Quantum Optics I, 2000) and Cozumel, Mexico (Quantum Optics II, 2004). About 115 participants from 19 countries attended and participated in the meeting to discuss a wide variety of topics such as quantum-information processing, experiments related to non-linear optics and squeezing, various aspects of entanglement including its sudden death, correlated twin-photon experiments, light storage, decoherence-free subspaces, Bose-Einstein condensation, discrete Wigner functions and many more. There was a strong Latin-American participation from Argentina, Brazil, Chile, Colombia, Peru, Uruguay, Venezuela and Mexico, as well as from Europe, USA, China, and Australia. New experimental and theoretical results were presented at the conference. In Latin-America a quiet revolution has taken place in the last twenty years. Several groups working in quantum optics and

    Building on a narrative synthesis of adoption theories by Wisdom et al. (2013), this review identifies 118 measures associated with the 27 adoption predictors in the synthesis. The distribution of measures is uneven across the predictors and predictors vary in modifiability. Multiple dimensions and definitions of predictors further complicate measurement efforts. For state policymakers and researchers, more effective and integrated measurement can advance the adoption of complex innovations such as evidence-based practices. PMID:24740175

    Tyrosinaemia type III is a rare disorder caused by a deficiency of 4-hydroxyphenylpyruvate dioxygenase, the second enzyme in the catabolic pathway of tyrosine. The majority of the nine previously reported patients have presented with neurological symptoms after the neonatal period, while others detected by neonatal screening have been asymptomatic. All have had normal liver and renal function and none has skin or eye abnormalities. A further four patients with tyrosinaemia type III are described. It is not clear whether a strict low tyrosine diet alters the natural history of tyrosinaemia type III, although there remains a suspicion that treatment may be important, at least in infancy.

    The lanthanides (III) and yttrium (III) glucoheptonates as well the D-glucoheptono 1-4 lactone were studied using common analytical methods, elemental microanalysis of carbon and hydrogen, thermogravimetry and differential scanning calorimetry. These compounds were prepared from the reaction between the lanthanides (III) and yttrium (III) hydroxides and glucoheptonic acid aqueous solution obtained by means of the delta lactone hydrolysis of this acid. After stoichiometric reaction the compounds were precipitated by the addition of absolute ethanol, washed with the same solvent and dried in desiccator. Thermogravimetric the (TG) curves of the lanthanides glucoheptonates of the ceric group present thermal profiles with enough differences permitting an easy caracterization of each compound and the yttrium (III) glucoheptonate TG curve showed a great similarity with the erbium (III) compound TG curve. The differential scanning calometry (DSC) curves showed endothermic and exothermic peaks by their shape, height and position (temperature) permit an easy and rapid identification of each compound specially if DSC and TG curves were examined simultaneously.

    We study the problem of optimal trading using general alpha predictors with linear costs and temporary impact. We do this within the framework of stochastic optimization with finite horizon using both limit and market orders. Consistently with other studies, we find that the presence of linear costs induces a no-trading zone when using market orders, and a corresponding market-making zone when using limit orders. We show that, when combining both market and limit orders, the problem is furthe...

    2015-12-01

    Full Text Available Background: Total fertility rate (TFR reflecting population growth is closely related to higher order parity progression. Many Indian states reached replacement level of TFR, but still states constituting nearly 40% population are with TFR ≥ 3. The predictors are the desire of son’s, poor contraceptives practices, younger age at marriage, child loss and shorter birth spacing. Objective: This analysis assessed the degree of relation of 3rd and higher order parity progression with the above mentioned predictors. Material and Methods: State/Union Territories wise proportions of women: progressing to ≥3 births, more sons desire, birth spacing <24 months, adopting modern contraception and median marriage age <18 years along with infant mortality rate (IMR were taken from NFHS-III report. Correlation matrix and stepwise forward multiple regression carried. Significance was seen at 5%. Results: Hindi speaking states constituting 38.92% nation population recorded TFR ≥3. Positive correlation of mothers progressing ≥ 3 births was highest (0.746 with those desiring more sons followed by IMR (0.445; while maximum negative correlation with those practicing modern contraceptives (-0.565 followed by median age at marriage (-0.391. Multiple regression analysis in order identified desire of more sons, practicing modern contraception and shorter birth spacing as the significant predictors and jointly explained 77.9% of the total variation with gain of 15.5% by adding modern contraceptive practice and 8.3% by adding shorter birth spacing. Conclusions: Desire of more sons appeared the most important predictor to progress ≥3 births that is governed by society culture and educational attainment, require attitudinal change. Further, mothers need motivation to practice both spacing and terminal methods once family is complete.

    Full Text Available Reliable growth data from trees are important to establish a rational forest management. Characteristics from trees, like the size, crown architecture and competition indices have been used to mathematically describe the increment efficiently when associated with them. However, the precise role of these effects in the growth-modeling destined to tropical trees needs to be further studied. Here it is reconstructed the basal area increment (BAI of individual Cedrela odorata trees, sampled at Amazon forest, to develop a growth- model using potential-predictors like: (1 classical tree size; (2 morphometric data; (3 competition and (4 social position including liana loads. Despite the large variation in tree size and growth, we observed that these kinds of predictor variables described well the BAI in level of individual tree. The fitted mixed model achieve a high efficiency (R2=92.7 % and predicted 3-years BAI over bark for trees of Cedrela odorata ranging from 10 to 110 cm at diameter at breast height. Tree height, steam slenderness and crown formal demonstrated high influence in the BAI growth model and explaining most of the growth variance (Partial R2=87.2%. Competition variables had negative influence on the BAI, however, explained about 7% of the total variation. The introduction of a random parameter on the regressions model (mixed modelprocedure has demonstrated a better significance approach to the data observed and showed more realistic predictions than the fixed model.

  1. Discriminating the reaction types of plant type III polyketide synthases.

    Science.gov (United States)

    2017-07-01

    Functional prediction of paralogs is challenging in bioinformatics because of rapid functional diversification after gene duplication events combined with parallel acquisitions of similar functions by different paralogs. Plant type III polyketide synthases (PKSs), producing various secondary metabolites, represent a paralogous family that has undergone gene duplication and functional alteration. Currently, there is no computational method available for the functional prediction of type III PKSs. We developed a plant type III PKS reaction predictor, pPAP, based on the recently proposed classification of type III PKSs. pPAP combines two kinds of similarity measures: one calculated by profile hidden Markov models (pHMMs) built from functionally and structurally important partial sequence regions, and the other based on mutual information between residue positions. pPAP targets PKSs acting on ring-type starter substrates, and classifies their functions into four reaction types. The pHMM approach discriminated two reaction types with high accuracy (97.5%, 39/40), but its accuracy decreased when discriminating three reaction types (87.8%, 43/49). When combined with a correlation-based approach, all 49 PKSs were correctly discriminated, and pPAP was still highly accurate (91.4%, 64/70) even after adding other reaction types. These results suggest pPAP, which is based on linear discriminant analyses of similarity measures, is effective for plant type III PKS function prediction. pPAP is freely available at ftp://ftp.genome.jp/pub/tools/ppap/. goto@kuicr.kyoto-u.ac.jp.

    Full Text Available Basel III banking regulation emphasizes the use of liquidity coverage and nett stable funding ratios as measures of liquidity risk. In this paper, we approximate these measures by using global liquidity data for 391 hand-selected, LIBOR-based, Basel II compliant banks in 36 countries for the period 2002 to 2012. In particular, we compare the risk sensitivity of the aforementioned Basel III liquidity risk measures to those of traditional measures such as the nonperforming assets ratio, return-on-assets, LIBOR-OISS, Basel II Tier 1 capital ratio, government securities ratio, and brokered deposits ratio. Furthermore, we use a discrete-time hazard model to study bank failure. In this regard, we find that Basel III risk measures have limited ability to predict bank failure when compared with their traditional counterparts. An important result is that a higher liquidity coverage ratio is associated with a higher bank failure rate. We also find that market-wide liquidity risk (proxied by LIBOR-OISS was the major predictor of bank failures in 2009 and 2010 while idiosyncratic liquidity risk (proxied by other liquidity risk measures was less. In particular, our contribution is the first to achieve these results on a global scale over a relatively long period for a variety of banks.

    The recurrence rate of pheochromocytoma after adrenalectomy is 6.5-16.5%. This study aims to identify predictors of recurrence and optimal biochemical testing and imaging for detecting the recurrence of pheochromocytoma. In this retrospective study we reviewed all patients who underwent adrenalectomy for pheochromocytoma during a 14-year period at a single institution. One hundred thirty-five patients had adrenalectomy for pheochromocytoma. Eight patients (6%) developed recurrent disease. The median time from initial operation to diagnosis of recurrence was 35 months. On multivariate analysis, tumor size >5 cm was an independent predictor of recurrence. One patient with recurrence died, 4 had stable disease, 2 had progression of disease, and 1 was cured. Recurrence was diagnosed by increases in plasma and/or urinary metanephrines and positive imaging in 6 patients (75%), and by positive imaging and normal biochemical levels in 2 patients (25%). Patients with large tumors (>5 cm) should be followed vigilantly for recurrence. Because 25% of patients with recurrence had normal biochemical levels, we recommend routine imaging and testing of plasma or urinary metanephrines for prompt diagnosis of recurrence.

    Storlie, Curtis B.; Helton, Jon C.

    2008-01-01

    The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Specifically, sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (i) locally weighted regression (LOESS), (ii) additive models, (iii) projection pursuit regression, and (iv) recursive partitioning regression. Then, in the second and concluding part of this presentation, the indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility (i.e., the Waste Isolation Pilot Plant). As shown by the example illustrations, the use of smoothing procedures based on nonparametric regression techniques can yield more informative sensitivity analysis results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and model predictions are present

    Studies of transuranic organometallic complexes provide a particularly valuable insight into covalent contributions to the metal-ligand bonding, in which the subtle differences between the transuranium actinide ions and their lighter lanthanide counterparts are of fundamental importance for the effective remediation of nuclear waste. Unlike the organometallic chemistry of uranium, which has focused strongly on U(III) and has seen some spectacular advances, that of the transuranics is significantly technically more challenging and has remained dormant. In the case of neptunium, it is limited mainly to Np(IV). Here we report the synthesis of three new Np(III) organometallic compounds and the characterization of their molecular and electronic structures. These studies suggest that Np(III) complexes could act as single-molecule magnets, and that the lower oxidation state of Np(II) is chemically accessible. In comparison with lanthanide analogues, significant d- and f-electron contributions to key Np(III) orbitals are observed, which shows that fundamental neptunium organometallic chemistry can provide new insights into the behaviour of f-elements.

    Purpose: To retrospectively assess prognostic factors and patterns of recurrence in patients with pathologic Stage III endometrial cancer. Methods and Materials: Between 1989 and 2003, 107 patients with pathologic International Federation of Gynecology and Obstetrics Stage III endometrial adenocarcinoma confined to the pelvis were treated at our institution. Adjuvant radiotherapy (RT) was delivered to 68 patients (64%). The influence of multiple patient- and treatment-related factors on pelvic and distant control and overall survival (OS) was evaluated. Results: Median follow-up for patients at risk was 41 months. Five-year actuarial OS was significantly improved in patients treated with adjuvant RT (68%) compared with those with resection alone (50%; p = 0.029). Age, histology, grade, uterine serosal invasion, adnexal involvement, number of extrauterine sites, and treatment with adjuvant RT predicted for improved survival in univariate analysis. Multivariate analysis revealed that grade, uterine serosal invasion, and treatment with adjuvant RT were independent predictors of survival. Five-year actuarial pelvic control was improved significantly with the delivery of adjuvant RT (74% vs. 49%; p = 0.011). Depth of myometrial invasion and treatment with adjuvant RT were independent predictors of pelvic control in multivariate analysis. Conclusions: Multiple prognostic factors predicting for the outcome of pathologic Stage III endometrial cancer patients were identified in this analysis. In particular, delivery of adjuvant RT seems to be a significant independent predictor for improved survival and pelvic control, suggesting that pelvic RT should be routinely considered in the management of these patients

Only 30% of oligodendroglial tumors have anaplastic characteristics. Anaplastic oligodendroglioma (AO is often localized as a single lesion in the white matter and in the cortex, rarely in brainstem or spinal cord. The management of AO is deeply changed in the recent years. Maximal safe surgical resection followed by radiotherapy (RT was considered as the standard of care since paramount findings regarding molecular aspects, in particular co-deletion of the short arm of chromosome 1 and the long arm of chromosome 19, revealed that these subsets of AO, benefit in terms of overall survival (OS and progression-free survival (PFS, from the addition of chemotherapy to RT. Allelic losses of chromosomes 1p and 19q occur in 50%–70% of both low-grade and anaplastic tumors, representing a strong prognostic factor and a powerful predictor of prolonged survival. Several other molecular markers have potential clinical significance as IDH1 mutations, confirming the strong prognostic role for OS. Malignant brain tumors negatively impacts on patients' quality of life. Seizures, visual impairment, headache, and cognitive disorders can be present. Moreover, chemotherapy and RT have important side effects. For these reasons, “health-related quality of life” is becoming a topic of growing interest, investigating on physical, mental, emotional, and social well-being. Understanding the impact of medical treatment on health-related quality of life will probably have a growing effect both on health care strategies and on patients.

    Full Text Available Background Subjects with metabolic syndrome (MetS have a greater risk for acquiring type 2 diabetes mellitus (type 2 DM. The MetS criteria usually used are those of the National Cholesterol Education Program Expert Panel (NCEP and Adult Treatment Panel III (ATP III and of the International Diabetes Federation (IDF. This study aimed to evaluate the modified NCEP-ATP III and IDF criteria as predictor of type 2 DM among subjects with MetS.   Methods A cohort study was conducted among 4240 subjects with MetS. MetS was determined according to the modified NCEP-ATP III and IDF criteria. The study followed up 3324 non-diabetic subjects of the cohort study of non-communicable disease (NCD risk factors (NCD study during a 2-year period. Type 2 DM was determined from the diagnosis by health personnel or from fasting blood glucose of ≥126 mg/dL or blood glucose of ≥200 mg/dL, 2 hours after 75g glucose loading.   Results The MetS prevalence based on modified NCEP ATP III and IDF criteria in non-DM subjects was 17.1% and 15.6%, respectively. The risk for DM in subjects with MetS using modified NCEP ATP III and IDF criteria was 4.7 (CI 95%: 3.4-6.5 and 4.1 (CI 95%: 3.0-5.7, respectively.   Conclusions Both MetS criteria can be used as predictors of the occurrence of DM type 2, but the modified NCEP-ATP III is more properly applied than the IDF criteria in subjects with MetS. Screening programs and routine monitoring of MetS components are required for early detection of type 2 DM.

    Full Text Available Our objective was to identify predictors of improved postthaw semen quality in men with testicular cancer banking sperm for fertility preservation. We reviewed 173 individual semen samples provided by 67 men with testicular germ cell tumor (TGCT who cryopreserved sperm before gonadotoxic treatment between 1994 and 2010 at our tertiary university medical center. Our main outcomes measures were independent predictors for the greater postthaw total motile count (TMC in men with TGCT. Men with NSGCT were more likely to be younger (P median fresh TMC each had increased odds of a postthaw TMC greater than median postthaw TMC. Interestingly, age, advanced cancer stage (II or III, rapid freezing protocol, and motility enhancer did not show increased odds of improved postthaw TMC in our models. In conclusion, men with TGCT or poor fresh TMC should consider preserving additional vials (at least 15 vials before oncologic treatment. Density gradient purification should be routinely used to optimize postthaw TMC in men with TGCT. Larger, randomized studies evaluating cancer stage and various cryopreservation techniques are needed to assist in counseling men with TGCT regarding fertility preservation and optimizing cryosurvival.

    The reaction of 2-acetylfuran-2-thenoylhydrazone(afth) with Ln(III) trichlorides yields complexes of the type [Ln(afth)Cl 2 (H 2 O)(EtOH)]Cl, [Ln(III) = La, Pr, Nd, Sm, Eu, Gd, Tb and Dy]. The complexes have been characterized by molar conductance, magnetic susceptibility and TGA and DTA measurements, magnetic susceptibility and TGA and DTA measurements, FAB mass, infrared, proton NMR, electronic absorption and emission spectra. The terbium complex is found to be monomer from the FAB mass spectrum. The IR and NMR spectra suggest neutral tridentate behaviour of the Schiff base. A coordination number seven is proposed around the metal ions. Emission spectra suggest C 3v , symmetry around the metal ion with capped octahedron geometry for the europium complex. (author)

    Full Text Available One of the cornerstones of the British literary review The Criterion, founded in 1922 by poet and editor T.S. Eliot that lasted until 1939 was its strong universal spirit, which led to the inclusion of texts and reports on the culture of other countries in its pages. The presence of Spain was notable, thanks mainly to the chronicles sent from Madrid by Antonio Marichalar, the contributions of English musicologist and hispanist John Brande Trend, and the reviews of the Revista de Occidente. The aim of this work is not to study the content of these contributions, but to explore and clarify the beginnings of the relationship between Eliot and those who facilitated the reception of the Spanish culture in his review. To this end, the extensive correspondence of the English-speaking poet has proved an invaluable and the main source for this study.Uno de los fundamentos de la revista inglesa The Criterion, fundada en 1922 por el poeta y editor T.S.

    A reliable predictor is very useful for real-world industrial applications to forecast the future behavior of dynamic systems. A smart predictor, based on a novel recurrent neural fuzzy (RNF) scheme, is developed in this paper for multi-step-ahead prediction of material properties. A systematic investigation based on two benchmark data sets is conducted in terms of performance and efficiency. Analysis results reveal that, of the data-driven forecasting schemes, predictors based on step input patterns outperform those based on sequential input patterns; the RNF predictor outperforms those based on recurrent neural networks and ANFIS schemes in multi-step-ahead prediction of nonlinear time series. An adaptive Levenberg–Marquardt training technique is adopted to improve the robustness and convergence of the RNF predictor. Furthermore, the proposed smart predictor is implemented for material property testing. Investigation results show that the developed RNF predictor is a reliable forecasting tool for material property testing; it can capture and track the system's dynamic characteristics quickly and accurately. It is also a robust predictor to accommodate different system conditions

    The Shielded Neutron Assay Probe (SNAP) technique was developed to determine the leakage neutron source strength of a radioactive object. The original system consisted of an EberlineTM Mini-scaler and discrete neutron detector. The system was operated by obtaining the count rate with the EberlineTM instrument, determining the absolute efficiency from a graph, and calculating the neutron source strength by hand. In 2003 the SNAP III, shown in Figure 1, was designed and built. It required the operator to position the SNAP, and then measure the source-to-detector and detectorto- reflector distances. Next the operator entered the distance measurements and started the data acquisition. The SNAP acquired the required count rate and then calculated and displayed the leakage neutron source strength (NSS). The original design of the SNAP III is described in SNAP III Training Manual (ER-TRN-PLN-0258, Rev. 0, January 2004, prepared by William Baird) This report describes some changes that have been made to the SNAP III. One important change is the addition of a LEMO connector to provide neutron detection output pulses for input to the MC-15. This feature is useful in active interrogation with a neutron generator because the MC-15 has the capability to only record data when it is not gated off by a pulse from the neutron generator. This avoids recording of a lot of data during the generator pulses that are not useful. Another change was the replacement of the infrared RS-232 serial communication output by a similar output via a 4-pin LEMO connector. The current document includes a more complete explanation of how to estimate the amount of moderation around a neutron-emitting source.

In this paper, we discuss the mechanism by which low- and high-quality entities securitize low- and high-quality assets, respectively, into collateralized debt obligations. During the 2007–2009 financial crisis, asset securitization was seriously inhibited. In response to this, for instance, new Basel III capital and liquidity regulations were introduced. Here, we find that we can explicitly determine the transaction costs related to low-quality asset securitization. Also, in the case of dynamic and static multipliers, the effects of unexpected negative shocks such as rating downgrades on asset price and input, debt obligation price and output, and profit will be quantified. In this case, we note that Basel III has been designed to provide countercyclical capital buffers to negate procyclicality. Moreover, we will develop an illustrative example of low-quality asset securitization for subprime mortgages. Furthermore, numerical examples to illustrate the key results will be provided. In addition, connections between Basel III and asset securitization will be highlighted.

    Studies of transuranic organometallic complexes provide a particularly valuable insight into covalent contributions to the metal-ligand bonding, in which the subtle differences between the transuranium actinide ions and their lighter lanthanide counterparts are of fundamental importance for the effective remediation of nuclear waste. Unlike the organometallic chemistry of uranium, which has focused strongly on UIII and has seen some spectacular advances, that of the transuranics is significantly technically more challenging and has remained dormant. In the case of neptunium, it is limited mainly to NpIV. Here we report the synthesis of three new NpIII organometallic compounds and the characterization of their molecular and electronic structures. These studies suggest that NpIII complexes could act as single-molecule magnets, and that the lower oxidation state of NpII is chemically accessible. In comparison with lanthanide analogues, significant d- and f-electron contributions to key NpIII orbitals are observed, which shows that fundamental neptunium organometallic chemistry can provide new insights into the behaviour of f-elements.

    Full Text Available Frente al excesivo consumo energético en el acondicionamiento térmico residencial, este estudio investiga la implicancia del clima local en las estrategias de expansión urbana, así como su grado de afección a las condiciones de confort, en el contexto mediterráneo español de la Costa del Sol Occidental. Para ello se realiza un análisis bioclimático territorial, identificando los diversos climas locales existentes y las diferentes respuestas biológicas asociadas a cada uno de ellos. Con estos resultados se elabora una clasificación del lugar desde la óptica de la idoneidad bioclimática. Esta herramienta ha permitido evaluar los procesos de planificación territorial, concluyéndose que el 80,6% del suelo urbano y urbanizable no se beneficia de las condiciones climáticas más favorables, las cuales constituyen el 47,3% del territorio analizado. Esta información, puesta al servicio de mejorar las condiciones térmicas de las ciudades, puede ser útil en el diseño y distribución de futuras áreas urbanas.

    Full Text Available El presente artículo muestra un diagnóstico del fenómeno migratorio así como un análisis de la distribución del ingreso, con y sin remesas, en la región centro occidente de México durante el periodo 2000-2008. Ello con la finalidad de distinguir el nivel de concentración del ingreso en la región y el papel que juegan las remesas. En el documento se podrá distinguir que tanto la población de origen mexicano que reside en Estados Unidos como las remesas que envían a sus comunidades de origen han aumentado. Por otro lado, a partir de la determinación del coeficiente de Gini, tomando como punto de referencia el ingreso corriente de los hogares con y sin transferencias (incluye al factor remesas, fue posible apreciar que la región y los estados que la conforman se caracterizaron durante el periodo de estudio por poseer altos niveles de concentración del ingreso y que las transferencias contribuyen en la disminución de la inequidad en la distribución del ingreso. Con ello se denota el importante papel que juegan las remesas en la vida de los hogares mexicanos.

    Full Text Available Abstract Background Since American Indians are predisposed to type 2 diabetes (DM2 and associated cardiovascular risk, Cherokee boys and girls (n = 917 were studied to determine whether BMI Z (body mass index Z score is associated with the apoC-III (apolipoprotein C-III content of HDL (high density lipoprotein, a previously reported predictor of DM2. Methods An ad hoc cross-sectional analysis was conducted on a previously studied cohort. Participants were grouped by gender-specific age groups (5 to 9, 10 to 14 and 15 to 19 years. ApoA-I (apolipoprotein A-I and HDL apoC-III were assayed by electroimmunoassay. ApoC-III was measured in whole plasma, and in HDL to determine the molar proportion to apoA-I. General linear models were used to assess association. Results The HDL apoC-III to apoA-I molar ratio increased by BMI Z quartile in girls aged 10–14 years (p  Conclusions ApoC-III showed an obesity-related increase relative to apoA-I during adolescence beginning in girls aged 10 to 14 years and in boys aged 15 to 19 years. The earlier changes in girls may alter HDL’s protective properties on the β-cell and contribute to their increased risk for DM2.

    The Sparkle/PM3 model is extended to europium(III), gadolinium(III), and terbium(III) complexes. The validation procedure was carried out using only high quality crystallographic structures, for a total of ninety-six Eu(III) complexes, seventy Gd(III) complexes, and forty-two Tb(III) complexes. The Sparkle/PM3 unsigned mean error, for all interatomic distances between the trivalent lanthanide ion and the ligand atoms of the first sphere of coordination, is: 0.080 A for Eu(III); 0.063 A for Gd(III); and 0.070 A for Tb(III). These figures are similar to the Sparkle/AM1 ones of 0.082 A, 0.061 A, and 0.068 A respectively, indicating they are all comparable parameterizations. Moreover, their accuracy is similar to what can be obtained by present-day ab initio effective core potential full geometry optimization calculations on such lanthanide complexes. Finally, we report a preliminary attempt to show that Sparkle/PM3 geometry predictions are reliable. For one of the Eu(III) complexes, BAFZEO, we created hundreds of different input geometries by randomly varying the distances and angles of the ligands to the central Eu(III) ion, which were all subsequently fully optimized. A significant trend was unveiled, indicating that more accurate local minima geometries cluster at lower total energies, thus reinforcing the validity of sparkle model calculations. (author)

  4. Europium (III) and americium (III) stability constants with humic acid

    Torres, R.A.; Choppin, G.R.

    1984-01-01

    The stability constants for tracer concentrations of Eu(III) and Am(III) complexes with a humic acid extracted from a lake-bottom sediment were measured using a solvent extraction system. The organic extractant was di(2-ethylhexyl)-phosphoric acid in toluene while the humate aqueous phase had a constant ionic strength of 0.1 M (NaClO 4 ). Aqueous humic acid concentrations were monitored by measuring uv-visible absorbances at approx.= 380 nm. The total carboxylate capacity of the humic acid was determined by direct potentiometric titration to be 3.86 +- 0.03 meq/g. The humic acid displayed typical characteristics of a polyelectrolyte - the apparent pKsub(a), as well as the calculated metal ion stability constants increased as the degree of ionization (α) increased. The binding data required a fit of two stability constants, β 1 and β 2 , such that for Eu, log β 1 = 8.86 α + 4.39, log β 2 = 3.55 α + 11.06 while for Am, log β 1 = 10.58 α + 3.84, log β 2 = 5.32 α + 10.42. With hydroxide, carbonate, and humate as competing ligands, the humate complex associated with the β 1 constant is calculated to be the dominant species for the trivalent actinides and lanthanides under conditions present in natural waters.

    The design and construction of the new Mark III vertex chamber is described. Initial tests with cosmic rays prove the ability of track reconstruction and yield triplet resolutions below 50 μm at 3 atm using argon/ethane (50:50). Also performed are studies using a prototype of a pressurized wire vertex chamber with 8 mm diameter straw geometry. Spatial resolution of 35mm was obtained using dimethyl ether (DME) at 1 atm and 30 μm using argon/ethane (50/50 mixture) at 4 atm. Preliminary studies indicate the DME to adversely affect such materials as aluminized Mylar and Delrin

    Full Text Available Background. The aims of this study were to evaluate the predictive value of admission Glasgow Coma Scale (GCS scores, duration of unconsciousness, neurosurgical intervention, and countercoup lesion on the impairment of memory and processing speed functions six months after a traumatic brain injury (TBI based on a structural equation modeling. Methods. Thirty TBI patients recruited from Neurosurgical Department at the Kaohsiung Medical University Hospital were administered the Wechsler Memory Scale-III (WMS-III and the Wechsler Adult Intelligence Scale-III processing speed index to evaluate the memory and processing speed functions. Results. The study showed that GCS scores accounted for 40% of the variance in memory/processing speed. No significant predictive effects were found for the other three variables. GCS classification at the time of TBI seems to correspond moderately to the severity of memory/processing speed dysfunctions. Conclusions. The present study demonstrated that admission GCS score is a robust predictor of memory/processing speed dysfunctions after TBI. The results should be replicated with a large sample of patients with TBI, or be extended by examining other potential clinical predictors.

    To determine the prognosis of seizures in epileptic children and identify early predictors of intractable childhood epilepsy. All children (aged 1 month to 16 years) with idiopathic or cryptogenic epilepsy who were treated and followed at the centre during the study period were included. The patients who had marked seizures even after two years of adequate treatment were labeled as intractable epileptics (cases). Children who had no seizure for more than one year at last follow-up visit were the controls. Adequate treatment was described as using at least three anti-epileptic agents either alone or in combination with proper compliance and dosage. Records of these patients were reviewed to identify the variables that may be associated with seizure intractability. Of 442 epileptic children, 325 (74%) intractable and 117 (26%) control epileptics were included in the study. Male gender (OR=3.92), seizures onset in infancy >10 seizures before starting treatment (OR=3.76), myoclonic seizures (OR=1.37), neonatal seizures (OR=3.69), abnormal EEG (OR=7.28) and cryptogenic epilepsy (OR=9.69) and head trauma (OR=4.07) were the factors associated with intractable epilepsy. Seizure onset between 5-7 years of age, idiopathic epilepsy, and absence seizures were associated with favourable prognosis in childhood epilepsy. Intractable childhood epilepsy is expected if certain risk factors such as type, age of onset, gender and cause of epilepsy are found. Early referral of such patients to the specialized centres is recommended for prompt and optimal management. (author)

    Flexible electronics using III-V materials for nano-electronics with high electron mobility and optoelectronics with direct band gap are attractive for many applications. This thesis describes a complementary metal oxide semiconductor (CMOS) compatible process for transforming traditional III-V materials based electronics into flexible one. The thesis reports releasing 200 nm of Gallium Arsenide (GaAs) from 200 nm GaAs / 300 nm Aluminum Arsenide (AlAs) stack on GaAs substrate using diluted hydrofluoric acid (HF). This process enables releasing a single top layer compared to peeling off all layers with small sizes at the same time. This is done utilizing a network of release holes that contributes to the better transparency (45 % at 724 nm wavelengths) observed. Fabrication of metal oxide semiconductor capacitor (MOSCAPs) on GaAs is followed by releasing it to have devices on flexible 200 nm GaAs. Similarly, flexible GaSb and InP fabrication process is also reported to transform traditional electronics into large-area flexible electronics.

    Full Text Available At the same time as the 17th-century emigration from the Iberian Peninsula to the Western Sephardic Diaspora took place, the reverse process also occurred. Several individuals who had belonged to these communities decided to return, temporarily or permanently, to Spain, Portugal, or their colonies, and were imprisoned and tried by the Inquisition. Trial documents provide us with some insight into the social and religious life of these communities. Using inquisitorial sources, this article discusses some aspects of the circumcision rite, education, and synagogue life in these communities and their function in socializing the New Christians who returned to Judaism.Paralelamente al proceso de emigración desde la Península Ibérica hacia las comunidades de la diáspora sefaradí occidental durante el siglo XVII, tuvo lugar un fenómeno en dirección contraria. Individuos que habían residido en el seno de estas congregaciones, decidieron retornar, temporal o definitivamente, a España, Portugal o sus colonias. Algunos de estos fueron procesados por la Inquisición. En los documentos de sus procesos de fe se encuentran interesantes descripciones a partir de las cuales se puede reconstruir algunos aspectos sociales y religiosos de la vida judía en dichas comunidades de la diáspora sefaradí. El presente artículo recoge una selección de fuentes inquisitoriales a partir de las cuales se abordan aspectos sobre el rito de la circuncisión, la educación y la vida sinagogal, y el papel que estos jugaron en el proceso de socialización de los cristianos nuevos que retornaron al judaísmo.

    Full Text Available Growth, recruitment, mortality and exploitation rate of the short-necked clam Paphia undulata (Born, 1778 were studied in southern Negros Occidental waters between August 2007 and July 2008 from length-frequency data derived from catches of divers, to be able to compare with earlier data derived and analyzed 13 years ago by Agasen et al. (1998. Both sets of data were analyzed using the FiSAT software (Gayanilo & Pauly, 1997. The asymptotic shell length (S¥ = 79 mm derived from the present data proved to be smaller compared to the earlier data (SL¥ = 81.5 mm due to the lack of bigger sizes in the present samples. The growth constant (K = 1.0 yr-1 was however comparable indicating it to be a more species-characteristic parameter. Two recruitment pulses for each study were derived and were found to be correlated with the spawning pattern in the species. The value of natural mortality (M = 1.57 yr-1 derived from bivalve literature, is deemed more appropriate compared to the earlier estimate (M = 2.89 yr-1 based on Pauly’s (1980 empirical equation developed for fish. Total mortality (Z values for both studies were comparable, but a higher level of fishing mortality (F = 4.61 yr-1 was estimated for the present data set, thus resulting likewise in a higher exploitation rate (E = 0.75. These, together with fishery information from an accompanying paper (Villarta & del Norte-Campos, 2010, not only validate the earlier findings of overexploitation due to lack of management, but reveal a worsening condition of the stock, most likely as a result of growth overfishing. Overexploitation can only be mitigated by imposing stringent restrictions in terms of the minimum size for exploitation (45 mm shell length and closed seasons during the spawning peak (August-November.

    Skaali, T.B.

    1980-10-01

    NODAL is a high level programming language based on FOCAL and SNOBOL4, with some influence from BASIC. The language was developed to operate on the computer network controlling the SPS accelerator at CERN. NODAL is an interpretive language designed for interactive use. This is the most important aspect of the language, and is reflected in its structure. The interactive facilities make it possible to write, debug and modify programs much faster than with compiler based languages like FORTRAN and ALGOL. Apart from a few minor modifications, the basic part of the Oslo University NODAL system does not differ from the CERN version. However, the Oslo University implementation has been expanded with new functions which enable the user to execute many of the SINTRAN III monitor calls from the NODAL level. In particular the most important RT monitor calls have been implemented in this way, a property which renders possible the use of NODAL as a RT program administrator. (JIW)

    Extraction of aluminum(III) and indium(III) with decanoic acid in 1-octanol was carried out at 25 deg C and at an aqueous ionic strength of 0.1 mol dm -3 (NaClO 4 ). Monomeric and tetrameric aluminum(III) decanoates and monomeric indium(III) decanoate are responsible for the extraction. From a comparison of the present results with those obtained from the previous works, the polymerization of the extracted species was found to be more extensive in benzene than in 1-octanol, and the metal decanoates were highly polymerized in the following order in both solvents: Al > Ga > In.

    Suicidal ideation and suicide attempts are serious but not rare conditions in adolescents. However, there are several research and practical suicide-prevention initiatives that discuss the possibility of preventing serious self-harm. Profound knowledge about risk and protective factors is therefore necessary. The aim of this study is a) to clarify the role of parenting behavior and parenting styles in adolescents' suicide attempts and b) to identify other statistically significant and clinically relevant risk and protective factors for suicide attempts in a representative sample of German adolescents. In the years 2007/2008, a representative written survey of N = 44,610 students in the 9th grade of different school types in Germany was conducted. In this survey, the lifetime prevalence of suicide attempts was investigated as well as potential predictors including parenting behavior. A three-step statistical analysis was carried out: I) As basic model, the association between parenting and suicide attempts was explored via binary logistic regression controlled for age and sex. II) The predictive values of 13 additional potential risk/protective factors were analyzed with single binary logistic regression analyses for each predictor alone. Non-significant predictors were excluded in Step III. III) In a multivariate binary logistic regression analysis, all significant predictor variables from Step II and the parenting styles were included after testing for multicollinearity. Three parental variables showed a relevant association with suicide attempts in adolescents - (all protective): mother's warmth and father's warmth in childhood and mother's control in adolescence (Step I). In the full model (Step III), Authoritative parenting (protective: OR: .79) and Rejecting-Neglecting parenting (risk: OR: 1.63) were identified as significant predictors (p parental separation events.

    The interpretation of religion in DSM-III-R contains considerable negative bias and contributes to unfair stereotypes of religious persons. Particularly new religious movements and religious conversion are unfairly interpreted under the DSM-III-R heading, 'Dissociative Disorder Not Otherwise Specified'. It is suggested that a more balanced and respectful interpretation of religion is needed in DSM-III-R, since psychiatry through its official nomenclature should not contribute to social intolerance of religious nonconformity.

    Bacterial ribonuclease III (RNase III) is a highly conserved endonuclease, which plays pivotal roles in RNA maturation and decay pathways by cleaving double-stranded structure of RNAs. Here we cloned rncS gene from the genomic DNA of Brucella melitensis, and analyzed the cleavage properties of RNase III from Brucella. We identified Brucella-encoding small RNA (sRNA) by high-throughput sequencing and northern blot, and found that sRNA of Brucella and Homo miRNA precursor (pre-miRNA) can be bound and cleaved by B.melitensis ribonuclease III (Bm-RNase III). Cleavage activity of Bm-RNase III is bivalent metal cations- and alkaline buffer-dependent. We constructed several point mutations in Bm-RNase III, whose cleavage activity indicated that the 133th Glutamic acid residue was required for catalytic activity. Western blot revealed that Bm-RNase III was differently expressed in Brucella virulence strain 027 and vaccine strain M5-90. Collectively, our data suggest that Brucella RNase III can efficiently bind and cleave stem-loop structure of small RNA, and might participate in regulation of virulence in Brucella.

    Limited research has investigated disability and functional impairment in trichotillomania (TTM) subjects. This study examined the relationships between hair pulling (HP) style and severity and disability while controlling for mood severity. Disability was measured in individual life areas (work, social, and family/home life) instead of as a total disability score as in previous studies. One hundred fifty three adult hair pullers completed several structured interviews and self-report instruments. HP style and severity, as well as depression, anxiety, and stress were correlated with work, social, and family/home life impairment on the Sheehan Disability Scale (SDS). Multiple regression analyses were performed to determine significant predictors of life impairment. Depressive severity was a significant predictor for all SDS life areas. In addition, interference/avoidance associated with HP was a predictor for work and social life disability. Distress from HP was a significant predictor of social and family/home life disability. Focused HP score and anxiety were significant predictors of family/home life disability. As expected, depression in hair pullers predicted disability across life domains. Avoiding work and social situations can seriously impair functioning in those life domains. Severity of distress and worry about HP may be most elevated in social situations with friends and family and thus predict impairment in those areas. Finally, since HP often occurs at home, time spent in focused hair pulling would have a greater negative impact on family and home responsibilities than social and work life.

    This study presents first steps towards verifying the hypothesis that uncertainty in global and regional glacier mass simulations can be reduced considerably by reducing the uncertainty in the high-resolution atmospheric input data. To this aim, we systematically explore the potential of different predictor strategies for improving the performance of regression-based downscaling approaches. The investigated local-scale target variables are precipitation, air temperature, wind speed, relative humidity and global radiation, all at a daily time scale. Observations of these target variables are assessed from three sites in geo-environmentally and climatologically very distinct settings, all within highly complex topography and in the close proximity to mountain glaciers: (1) the Vernagtbach station in the Northern European Alps (VERNAGT), (2) the Artesonraju measuring site in the tropical South American Andes (ARTESON), and (3) the Brewster measuring site in the Southern Alps of New Zealand (BREWSTER). As the large-scale predictors, ERA interim reanalysis data are used. In the applied downscaling model training and evaluation procedures, particular emphasis is put on appropriately accounting for the pitfalls of limited and/or patchy observation records that are usually the only (if at all) available data from the glacierized mountain sites. Generalized linear models and beta regression are investigated as alternatives to ordinary least squares regression for the non-Gaussian target variables. By analyzing results for the three different sites, five predictands and for different times of the year, we look for systematic improvements in the downscaling models' skill specifically obtained by (i) using predictor data at the optimum scale rather than the minimum scale of the reanalysis data, (ii) identifying the optimum predictor allocation in the vertical, and (iii) considering multiple (variable, level and/or grid point) predictor options combined with state

    The aim of this study was to examine the relationships among education, leadership experience, emotional intelligence and transformational leadership of nurse managers. Nursing leadership research provides limited evidence of predictors of transformational leadership style in nurse managers. A predictive correlational design was used with a sample of nurse managers (n = 148) working in varied health care settings. Data were collected using the Genos Emotional Intelligence Inventory, the Multi-factor Leadership Questionnaire and a demographic questionnaire. Simple linear and multiple regression analyses were used to examine relationships. A statistically significant relationship was found between emotional intelligence and transformational leadership (r = 0.59, P transformational leadership. Nurse managers should be well informed of the predictors of transformational leadership in order to pursue continuing education and development opportunities related to those predictors. The results of this study emphasise the need for emotional intelligence continuing education, leadership development and leader assessment programmes. © 2016 John Wiley & Sons Ltd.

    The dependence of Moessbauer spectra with pH value of Fe(III)HEDTA and Fe(III)CDTA compounds is studied. Informations on formation processes of LFe-O-FeL (L=ligand) type dimers by the relation of titration curves of Fe(III)EDTA, Fe(III)HEDTA and Fe(III)CDTA compounds with the series of Moessbauer spectra, are obtained. Some informations on Fe-O-Fe bond structure are also obtained. Comparing the titration curves with the series of Moessbauer spectra, it is concluded that the dimerization process begins when a specie of the form FeXOH α (X = EDTA, HEDTA, CDTA; α = -1, -2) arises.

    2017-10-03

    The ability to predict epitopes plays an enormous role in vaccine development in terms of our ability to zero in on where to do a more thorough in-vivo analysis of the protein in question. Though for the past decade there have been numerous advancements and improvements in epitope prediction, on average the best benchmark prediction accuracies are still only around 60%. New machine learning algorithms have arisen within the domain of deep learning, text mining, and convolutional networks. This paper presents a novel analytically trained and string kernel using deep neural network, which is tailored for continuous epitope prediction, called: Deep Ridge Regressed Epitope Predictor (DRREP). DRREP was tested on long protein sequences from the following datasets: SARS, Pellequer, HIV, AntiJen, and SEQ194. DRREP was compared to numerous state of the art epitope predictors, including the most recently published predictors called LBtope and DMNLBE. Using area under ROC curve (AUC), DRREP achieved a performance improvement over the best performing predictors on SARS (13.7%), HIV (8.9%), Pellequer (1.5%), and SEQ194 (3.1%), with its performance being matched only on the AntiJen dataset, by the LBtope predictor, where both DRREP and LBtope achieved an AUC of 0.702. DRREP is an analytically trained deep neural network, thus capable of learning in a single step through regression. By combining the features of deep learning, string kernels, and convolutional networks, the system is able to perform residue-by-residue prediction of continues epitopes with higher accuracy than the current state of the art predictors.

  5. Application of Interval Predictor Models to Space Radiation Shielding

    Crespo, Luis G.; Kenny, Sean P.; Giesy,Daniel P.; Norman, Ryan B.; Blattnig, Steve R.

    2016-01-01

    This paper develops techniques for predicting the uncertainty range of an output variable given input-output data. These models are called Interval Predictor Models (IPM) because they yield an interval valued function of the input. This paper develops IPMs having a radial basis structure. This structure enables the formal description of (i) the uncertainty in the models parameters, (ii) the predicted output interval, and (iii) the probability that a future observation would fall in such an interval. In contrast to other metamodeling techniques, this probabilistic certi cate of correctness does not require making any assumptions on the structure of the mechanism from which data are drawn. Optimization-based strategies for calculating IPMs having minimal spread while containing all the data are developed. Constraints for bounding the minimum interval spread over the continuum of inputs, regulating the IPMs variation/oscillation, and centering its spread about a target point, are used to prevent data over tting. Furthermore, we develop an approach for using expert opinion during extrapolation. This metamodeling technique is illustrated using a radiation shielding application for space exploration. In this application, we use IPMs to describe the error incurred in predicting the ux of particles resulting from the interaction between a high-energy incident beam and a target.

    Co-management of the actinides in an integrated closed fuel cycle by a pyrochemical process is studied at the laboratory scale in France in the CEA-ATALANTE facility. In this context the co-precipitation of U(III) and Pu(III) by wet argon sparging in LiCl-CaCl2 (30-70 mol%) molten salt at 705 °C is studied. Pu(III) is prepared in situ in the molten salt by carbochlorination of PuO2 and U(III) is then introduced as UCl3 after chlorine purge by argon to avoid any oxidation of uranium up to U(VI) by Cl2. The oxide conversion yield through wet argon sparging is quantitative. However, the preferential oxidation of U(III) in comparison to Pu(III) is responsible for a successive conversion of the two actinides, giving a mixture of UO2 and PuO2 oxides. Surprisingly, the conversion of sole Pu(III) in the same conditions leads to a mixture of PuO2 and PuOCl, characteristic of a partial oxidation of Pu(III) to Pu(IV). This is in contrast with coconversion of U(III)-Pu(III) mixtures but in agreement with the conversion of Ce(III).

    Adsorption behavior of Eu(III) and Cm(III) by Bacillus subtilis and Halobacterium salinarum was investigated. Both microorganisms showed almost identical pH dependence on the distribution ratio (K d ) of the metals examined, i.e., K d of Eu(III) and Cm(III) increased with an increase of pH. The coordination state of Eu(III) adsorbed on the microorganisms was studied by time-resolved laser-induced fluorescence spectroscopy (TRLFS). The coordination states of Eu(III) adsorbed on the B. subtilis and H. salinarum was of different characteristics. H. salinarum exhibited more outer-spherical interaction with Eu(III) than B. subtilis. (author)

    Agitation in critically ill adults is a frequent complication of hospitalization and results in multiple adverse outcomes. Potential causes of agitation are numerous; however, data on factors predictive of agitation are limited. To identify predictors of agitation by examining demographic and clinical characteristics of critically ill patients. A medical record review was performed. Documentation of agitation was indicated by scores on the Richmond Agitation-Sedation Scale or the use of an agitation keyword. Records of 200 patients from 1 medical and 1 surgical intensive care unit were used for the study. Risk factors were determined for 2 points in time: admission to the intensive care unit and within 24 hours before the first episode of agitation. Data on baseline demographics, preadmission risk factors, and clinical data were collected and were evaluated by using logistic multivariable regression to determine predictors of agitation. Predictors of agitation on admission to intensive care were history of use of illicit substances, height, respiratory and central nervous system subscores on the Sequential Organ Failure Assessment, and use of restraints. Predictors of agitation within 24 hours before the onset of agitation were history of psychiatric diagnosis, height, score on the Sequential Organ Failure Assessment, ratio of Pao2 to fraction of inspired oxygen less than 200, serum pH, percentage of hours with restraints, percentage of hours of mechanical ventilation, pain, and presence of genitourinary catheters. Predictors of agitation on admission and within 24 hours before the onset of agitation were primarily clinical variables. ©2014 American Association of Critical-Care Nurses.

    Teaching profession is characterised by an above-average rate of psychosomatic and mental health impairment due to work-related stress. The aim of the study was to identify predictors of mental health in female teachers. A sample of 630 female teachers (average age 47 ± 7 years) participated in a screening diagnostic inventory. Mental health was surveyed with the General Health Questionnaire GHQ-12. The following parameters were measured: specific work conditions (teacher-specific occupational history), scales of the Effort-Reward-Imbalance (ERI) Questionnaire as well as cardiovascular risk factors, physical complaints (BFB) and personal factors such as inability to recover (FABA), sense of coherence (SOC) and health behaviour. First, mentally fit (MH(+)) and mentally impaired teachers (MH(-)) were differentiated based on the GHQ-12 sum score (MH(+): teachers showed evidence of mental impairment. There were no differences concerning work-related and cardiovascular risk factors as well as health behaviour between MH(+) and MH(-). Binary logistic regressions identified 4 predictors that showed a significant effect on mental health. The effort-reward-ratio proved to be the most relevant predictor, while physical complaints as well as inability to recover and sense of coherence were identified as advanced predictors (explanation of variance: 23%). Contrary to the expectations, classic work-related factors can hardly contribute to the explanation of mental health. Additionally, cardiovascular risk factors and health behaviour have no relevant influence. However, effort-reward-ratio, physical complaints and personal factors are of considerable influence on mental health in teachers. These relevant predictors should become a part of preventive arrangements for the conservation of teachers' health in the future.

    Full Text Available Timing of orthodontic treatment, especially for children with developing class III malocclusions, has always been somewhat controversial, and definitive treatment tends to be delayed for severe class III cases. Developing class III patients with moderate to severe anterior crossbite and deep bite may need early intervention in some selected cases. Class III malocclusion may develop in children as a result of an inherent growth abnormality, i.e. true class III malocclusion, or as a result of premature occlusal contacts causing forward functional shift of the mandible, which is known as pseudo class III malocclusion. These cases, if not treated at the initial stage of development, interfere with normal growth of the jaw bases and may result in severe facial deformities. The treatment should be carried out as early as possible for permitting normal growth of the skeletal bases. This paper deals with the selection of an appropriate appliance from the various current options available for early intervention in developing class III malocclusion through two case reports.

    The purpose of this study was to identify the risk of concomitant glenohumeral pathologies with acromioclavicular joint injuries grade III and V. Patients who underwent arthroscopically-assisted stabilization of acromioclavicular joint injuries grade III or grade V between 01/2007 and 12/2015 were identified in the patient databases of two surgical centres. Gender, age at index surgery, grade of acromioclavicular joint injury (Rockwood III or Rockwood V), and duration between injury and index surgery (classified as acute or chronic) were of interest. Concomitant glenohumeral pathologies were noted and their treatment was classified as debridement or reconstructive procedure. A total of 376 patients (336 male, 40 female) were included. Mean age at time of arthroscopic acromioclavicular joint reconstruction surgery was 42.1 ± 14.0 years. Overall, 201 patients (53%) had one or more concomitant glenohumeral pathologies. Lesions of the biceps tendon complex and rotator cuff were the most common. Forty-five patients (12.0%) had concomitant glenohumeral pathologies that required an additional repair. The remaining 156 patients (41.5%) received a debridement of their concomitant pathologies. Rockwood grade V compared to Rockwood grade III (p = 0.013; odds ratio 1.7), and chronic compared to acute injury were significantly associated with having a concomitant glenohumeral pathology (p = 0.019; odds ratio 1.7). The probability of having a concomitant glenohumeral pathology was also significantly associated with increasing age (p acromioclavicular joint injury of either grade III or V. Twenty-two percent of these patients with concomitant glenohumeral pathologies received an additional dedicated repair procedure. Although a significant difference in occurrence of concomitant glenohumeral pathologies was seen between Rockwood grades III and V, and between acute and chronic lesions, increasing age was identified as the most dominant predictor.

    2015-01-01

    A radio-selected sample of fast drift radio bursts with complex structure occurring after the impulsive phase of the associated flare (“Type III-L bursts”) is identified by inspection of radio dynamic spectra from 1 to 180 MHz for over 300 large flares in 2001. An operational definition that takes into account previous work on these radio bursts starting from samples of solar energetic particle (SEP) events is applied to the data, and 66 Type III-L bursts are found in the sample. In order to determine whether the presence of these radio bursts can be used to predict the occurrence of SEP events, we also develop a catalog of all SEP proton events in 2001 using data from the ERNE detector on the SOHO satellite. 68 SEP events are found, for 48 of which we can identify a solar source and hence look for associated Type III-L emission. We confirm previous work that found that most (76% in our sample) of the solar sources of SEP events exhibit radio emission of this type. However, the correlation in the opposite direction is not as strong: starting from a radio-selected sample of Type III-L events, around 64% of the bursts that occur at longitudes magnetically well-connected to the Earth, and hence favorable for detection of SEPs, are associated with SEP events. The degree of association increases when the events have durations over 10 minutes at 1 MHz, but in general Type III-L bursts do not perform any better than Type II bursts in our sample as predictors of SEP events. A comparison of Type III-L timing with the arrival of near-relativistic electrons at the ACE spacecraft is not inconsistent with a common source for the accelerated electrons in both phenomena.

    This report provides thermodynamic data for predicting concentrations of Pu(III), Am(III), and Cm(III) in geologic environments, and contributes to an integration of the JNC chemical thermodynamic database, JNC-TDB (previously PNC-TDB), for the performance analysis of geological isolation system for high-level radioactive wastes. Thermodynamic data for the formation of complexes or compounds with hydroxide, chloride, fluoride, carbonate, nitrate, sulfate and phosphate are discussed in this report. Where data for specific actinide(III) species are lacking, the data were selected based on chemical analogy to other trivalent actinides. In this study, the Pitzer ion-interaction model is mainly used to extrapolate thermodynamic constants to zero ionic strength at 25degC. (author)

    Idiopathic pulmonary fibrosis (IPF) is a progressive interstitial lung disease with a poor prognosis. Recently, pirfenidone was reported to slow the rate of decline in vital capacity and improve progression-free survival in IPF. The purpose of this study was to clarify the factors that predicted a good response to pirfenidone, as well as its adverse effects. Forty-one IPF cases, treated with pirfenidone from January 2009 to January 2011, were enrolled in this investigation. Disease severity was classified into grades I-IV, as defined by the Japanese Respiratory Society (JRS). Short-term responsiveness to pirfenidone was evaluated by the modified criteria of the JRS. Predictors of nausea, anorexia, or both that represented important adverse effects were examined by multivariate Cox proportional hazard analyses. Predictors of short-time responsiveness were examined by multivariate logistic regression analyses. Diagnosed by a surgical lung biopsy (SLB), the mild cases of grade I/II were predictors of good, short-term responsiveness. Patients taking acid-secretion inhibitors, including proton pump inhibitors and histamine H2-receptor antagonists, showed less anorexia, nausea, or both. Only 1 case was administered drugs to activate gastrointestinal motility. We concluded that IPF patients with a mild disease, diagnosis by SLB, or both showed indications of a good response to pirfenidone. In addition, acid-secretion inhibitors may reduce the frequency of anorexia, nausea, or both from pirfenidone. © 2013 The Japanese Respiratory Society. Published by Elsevier B.V.

    We investigated the association of europium(III) and curium(III) with the microorganisms Chlorella vulgaris, Bacillus subtilis, Pseudomonas fluorescens, Halomonas sp., Halobacterium salinarum, and Halobacterium halobium. We determined the kinetics and distribution coefficients (K d ) for Eu(III) and Cm(III) sorption at pH 3-5 by batch experiments, and evaluated the number of water molecules in the inner-sphere (N H 2 O ) and the degree of strength of ligand field (R E/M ) for Eu(III) by time-resolved laser-induced fluorescence spectroscopy (TRLFS). Exudates from C. vulgaris, Halomonas sp., and H. halobium had an affinity for Eu(III) and Cm(III). The log K d of Eu(III) and Cm(III) showed that their sorption was not fully due to the exchange with three protons on the functional groups on cell surfaces. The halophilic microorganisms (Halomonas sp., Halobacterium salinarum, H. halobium) showed almost no pH dependence in log K d , indicating that an exchange with Na + on the functional groups was involved in their sorption. The ΔN H 2 O (= 9 - N H 2 O ) for Eu(III) on C. vulgaris was 1-3, while that for the other microorganisms was over 3, demonstrating that the coordination of Eu(III) with C. vulgaris was predominantly an outer-spherical process. The R E/M for Eu(III) on halophilic microorganisms was 2.5-5, while that for non-halophilic ones was 1-2.5. This finding suggests that the coordination environment of Eu(III) on the halophilic microorganisms is more complicated than that on the other three non-halophilic ones. (orig.)

The log K{sub d} of Eu(III) and Cm(III) showed that their sorption was not fully due to the exchange with three protons on the functional groups on cell surfaces. The halophilic microorganisms (Halomonas sp., Halobacterium salinarum, H. halobium) showed almost no pH dependence in log K{sub d}, indicating that an exchange with Na{sup +} on the functional groups was involved in their sorption. The {delta}N{sub H{sub 2}O} (= 9 - N{sub H{sub 2}O}) for Eu(III) on C. vulgaris was 1-3, while that for the other microorganisms was over 3, demonstrating that the coordination of Eu(III) with C. vulgaris was predominantly an outer-spherical process. The R{sub E/M} for Eu(III) on halophilic microorganisms was 2.5-5, while that for non-halophilic ones was 1-2.5. This finding suggests that the coordination environment of Eu(III) on the halophilic microorganisms is more complicated than that on the other three non-halophilic ones. (orig.)

    This paper presents the results of JET experiments aimed at studying the operational space of plasmas with a Type III ELMy edge, in terms of both local and global plasma parameters. In JET, the Type III ELMy regime has a wide operational space in the pedestal n{sub e} - T{sub e} diagram, and Type III ELMs are observed in standard ELMy H-modes as well as in plasmas with an internal transport barrier (ITB). The transition from an H-mode with Type III ELMs to a steady state Type I ELMy H-mode requires a minimum loss power, P{sub TypeI}. P{sub TypeI} decreases with increasing plasma triangularity. In the pedestal n{sub e} - T{sub e} diagram, the critical pedestal temperature for the transition to Type I ELMs is found to be inversely proportional to the pedestal density (T{sub crit} {proportional_to} 1/n) at a low density. In contrast, at a high density, T{sub crit}, does not depend strongly on density. In the density range where T{sub crit} {proportional_to} 1/n, the critical power required for the transition to Type I ELMs decreases with increasing density. Experimental results are presented suggesting a common mechanism for Type III ELMs at low and high collisionality. A single model for the critical temperature for the transition from Type III to Type I ELMs, based on the resistive interchange instability with magnetic flutter, fits well the density and toroidal field dependence of the JET experimental data. On the other hand, this model fails to describe the variation of the Type III n{sub e} - T{sub e} operational space with isotopic mass and q{sub 95}. Other results are instead suggestive of a different physics for Type III ELMs. At low collisionality, plasma current ramp experiments indicate a role of the edge current in determining the transition from Type III to Type I ELMs, while at high collisionality, a model based on resistive ballooning instability well reproduces, in term of a critical density, the experimentally observed q{sub 95} dependence of the

    Intermolecular exchange interactions in iron(III) porphyrin chlorides (porphyrin = OEP, proto, TPP) have been studied by X-ray structure, EPR and magnetic susceptibility studies. The crystal structure of Fe(III)OEP-Cl was found to be different from that of the other two. Different types of exchange broadened EPR-spectra are obtained which are attributable to the arrangement in the crystals. The EPR results correlate well with magnetic susceptibility data. (orig.)

  11. Complexation of trivalent actinides and lanthanides with hydrophilic N-donor ligands for Am(III)/Cm(III) and An(III)/Ln(III) separation; Komplexierung von trivalenten Actiniden und Lanthaniden mit hydrophilen N-Donorliganden zur Am(III)/Cm(III)- bzw. An(III)/Ln(III)-Trennung

    The implementation of actinide recycling processes is considered in several countries, aiming at the reduction of long-term radiotoxicity and heat load of used nuclear fuel. This requires the separation of the actinides from the fission and corrosion products. The separation of the trivalent actinides (An(III)) Am(III) and Cm(III), however, is complicated by the presence of the chemically similar fission lanthanides (Ln(III)). Hydrophilic N-donor ligands are employed as An(III) or Am(III) selective complexing agents in solvent extraction to strip An(III) or Am(III) from an organic phase loaded with An(III) and Ln(III). Though they exhibit excellent selectivity, the complexation chemistry of these ligands and the complexes formed during solvent extraction are not sufficiently characterized. In the present thesis the complexation of An(III) and Ln(III) with hydrophilic N-donor ligands is studied by time resolved laser fluorescence spectroscopy (TRLFS), UV/Vis, vibronic sideband spectroscopy and solvent extraction. TRLFS studies on the complexation of Cm(III) and Eu(III) with the Am(III) selective complexing agent SO{sub 3}-Ph-BTBP (tetrasodium 3,3{sup '},3'',3{sup '''}-([2,2{sup '}-bipyridine]-6,6{sup '}-diylbis(1,2,4-triazine-3,5,6-triyl)) tetrabenzenesulfonate) revealed the formation of [M(SO{sub 3}-Ph-BTBP){sub n}]{sup (4n-3)-} complexes (M = Cm(III), Eu(III); n = 1, 2). The conditional stability constants were determined in different media yielding two orders of magnitude larger β{sub 2}-values for the Cm(III) complexes, independently from the applied medium. A strong impact of ionic strength on the stability and stoichiometry of the formed complexes was identified, resulting from the stabilization of the pentaanionic [M(SO{sub 3}-Ph-BTBP){sub 2}]{sup 5-} complex with increasing ionic strength. Thermodynamic studies of Cm(III)-SO{sub 3}-Ph-BTBP complexation showed that the proton concentration of the applied medium impacts

    This study evaluated gender differences in the cephalometric records of a large-scale cross-sectional sample of Caucasian subjects with Class III malocclusion at different developmental ages. The purpose also was to provide average age-related and sex-related data for craniofacial measures in untreated Class III subjects that are used as reference in the diagnostic appraisal of the patient with Class III disharmony. The sample examined consisted of 1094 pretreatment lateral cephalometric records (557 female subjects and 537 male subjects) of Caucasian Class III individuals. The age range for female subjects was between three years six months and 57 years seven months. The male subject group ranged from three years three months to 48 years five months. Twelve age groups were identified. Skeletal maturity at different age periods also was determined using the stage of cervical vertebral maturation. Gender differences for all cephalometric variables were analyzed using parametric statistics. The findings of the study indicated that Class III malocclusion is associated with a significant degree of sexual dimorphism in craniofacial parameters, especially from the age of 13 onward. Male subjects with Class III malocclusion present with significantly larger linear dimensions of the maxilla, mandible, and anterior facial heights when compared with female subjects during the circumpubertal and postpubertal periods.

    There are few data on the role of liver dysfunction in patients with end-stage heart failure supported by mechanical circulatory support. The aim of our study was to investigate predictors for acute liver failure in patients with end-stage heart failure undergoing mechanical circulatory support. A consecutive 164 patients with heart failure with New York Heart Association class IV undergoing mechanical circulatory support were investigated for acute liver failure using the King's College criteria. Clinical characteristics of heart failure together with hemodynamic and laboratory values were analyzed by logistic regression. A total of 45 patients (27.4%) with heart failure developed subsequent acute liver failure with a hospital mortality of 88.9%. Duration of heart failure, cause, cardiopulmonary resuscitation, use of vasopressors, central venous pressure, pulmonary capillary wedge pressure, pulmonary pulsatility index, cardiac index, and transaminases were not significantly associated with acute liver failure. Repeated decompensation, atrial fibrillation (P failure in univariate analysis only. In multivariable analysis, decreased antithrombin III was the strongest single measurement indicating acute liver failure (relative risk per %, 0.84; 95% confidence interval, 0.77-0.93; P = .001) and remained an independent predictor when adjustment for the Model for End-Stage Liver Disease score was performed (relative risk per %, 0.89; 95% confidence interval, 0.80-0.99; P = .031). Antithrombin III less than 59.5% was identified as a cutoff value to predict acute liver failure with a corresponding sensitivity of 81% and specificity of 87%. In addition to the Model for End-Stage Liver Disease score, decreased antithrombin III activity tends to be superior in predicting acute liver failure compared with traditionally thought predictors. Antithrombin III measurement may help to identify patients more precisely who are developing acute liver failure during mechanical

    Following a recent classification of the VATER Association provided by the CURE-Net consortium (submitted), we investigate medical predictors of psychological stress and anxieties in this particular condition. We developed a new set of questionnaires measuring psychological adjustment and quality of life outcome in conditions associated with anorectal and/or urogenital malformation (one self- report form to be completed by patients 7-17 years of age, two parent report forms with one relating to patients with an age range of 0-6 years, resp. 7-17 years of age). The questionnaire "Malformation-related Stress and Anxieties" comprises 26 items belonging to five subscales (I. Functional and cosmetic impairment, II. Intimacy and relationship, III. Social inclusion, IV. Psychological functioning, V. Family functioning). Every item can be responded to with respect to both actual, present problems already experienced as well as to future anxieties anticipating future development and adjustment (a perspective which especially applies in younger patients). Internal consistencies of the scales are good, resp. very good (Cronbach's α = .85 concerning present sources of anxiety scale, resp., .94 concerning future anxieties scale). The items are supplied with a Likert-type 5-point scale. We administered the questionnaire in N = 17 children and adolescents suffering from VATER via parental (proxy) report. As most medical risk factors affected nearly the entire sample, statistical analysis excluded investigation of differential impact on psychological stress experience and anxieties in subjects exposed versus not exposed. Special attention, therefore, was paid to those medical parameters with the best statistical power to differentiate between individuals of high versus low psychological outcome. Medical predictors differentiating between individuals with high versus low adjustment comprise post-operative infections of the urinary tract (t[15] = -3.78, p = .09), wound

    Effective and simple screening tools are needed to detect behaviors that are established early in life and have a significant influence on weight gain later in life. Crowdsourcing could be a novel and potentially useful tool to assess childhood predictors of adult obesity. This exploratory study examined whether crowdsourcing could generate well-documented predictors in obesity research and, moreover, whether new directions for future research could be uncovered. Participants were recruited through social media to a question-generation website, on which they answered questions and were able to pose new questions that they thought could predict obesity. During the two weeks of data collection, 532 participants (62% female; age  =  26.5±6.7; BMI  =  29.0±7.0) registered on the website and suggested a total of 56 unique questions. Nineteen of these questions correlated with body mass index (BMI) and covered several themes identified by prior research, such as parenting styles and healthy lifestyle. More importantly, participants were able to identify potential determinants that were related to a lower BMI, but have not been the subject of extensive research, such as parents packing their children's lunch to school or talking to them about nutrition. The findings indicate that crowdsourcing can reproduce already existing hypotheses and also generate ideas that are less well documented. The crowdsourced predictors discovered in this study emphasize the importance of family interventions to fight obesity. The questions generated by participants also suggest new ways to express known predictors.

    The Bentall operation is a 40-year-old standardized procedure for treating aortic valve diseases and aneurysms involving the aortic root. The study aim was to analyze the results and predictors of long-term outcome after the Bentall procedure for aortic root diseases. Between January 1990 and December 2007, a total of 375 patients (296 males, 79 females) underwent the Bentall operation at the authors' institution. Bicuspid aortic valve (BAV) was present in 91 patients, and Marfan syndrome in 13. Thirty-six patients were treated as emergencies, and 30 for acute dissection. A concomitant surgical procedure was performed in 78 patients. The operative procedure included both classic Bentall and button techniques. Follow up data were obtained from hospital and office records and from telephone contacts. Kaplan-Meier survival analysis and Cox regression analysis were performed to investigate the predictors of long-term outcome. The overall in-hospital mortality was 4.5%, and after elective operations was 2.3%. A 20-year long-term follow up included 32 late deaths, of which 14 were cardiac-related. Freedom from late all-cause mortality at 5, 10, and 15 years was 97.1%, 81.9%, and 53.9%, respectively. At univariate analysis, long-term mortality was associated with age, diabetes, BAV, NYHA class III/IV, emergency treatment, cardiopulmonary bypass time, and coronary artery bypass grafting. Independent predictors of long-term mortality were age (OR 1.16; CI: 1.08-1.23), emergency surgery (OR 28; CI: 4-192) and BAV (OR 3; CI: 1.3-6.9). The Bentall procedure is a safe and durable operation, with a very good early and long-term results and a low rate of reoperation. In the present series, age, BAV and emergency surgery were important independent predictors of mortality.

    Despite emerging evidence that foot problems and inappropriate footwear increase the risk of falls, there is little evidence as to whether foot-related intervention strategies can be successfully implemented. The aim of this study was to evaluate adherence rates, barriers to adherence, and the predictors of adherence to a multifaceted podiatry intervention for the prevention of falls in older people. The intervention group (n = 153, mean age 74.2 years) of a randomised trial that investigated the effectiveness of a multifaceted podiatry intervention to prevent falls was assessed for adherence to the three components of the intervention: (i) foot orthoses, (ii) footwear advice and footwear cost subsidy, and (iii) a home-based foot and ankle exercise program. Adherence to each component and the barriers to adherence were documented, and separate discriminant function analyses were undertaken to identify factors that were significantly and independently associated with adherence to the three intervention components. Adherence to the three components of the intervention was as follows: foot orthoses (69%), footwear (54%) and home-based exercise (72%). Discriminant function analyses identified that being younger was the best predictor of orthoses use, higher physical health status and lower fear of falling were independent predictors of footwear adherence, and higher physical health status was the best predictor of exercise adherence. The predictive accuracy of these models was only modest, with 62 to 71% of participants correctly classified. Adherence to a multifaceted podiatry intervention in this trial ranged from 54 to 72%. People with better physical health, less fear of falling and a younger age exhibited greater adherence, suggesting that strategies need to be developed to enhance adherence in frailer older people who are most at risk of falling.

    The incidence of skin cancer, the most common type of cancer in the United States, is increasing. Sunburn is a major modifiable risk factor for skin cancer, and its prevalence among the US population is high. To identify predictors of having had a red or painful sunburn in the past 12 months among people living in Florida. Florida residents were recruited from public places and online. They were asked to complete an anonymous cross-sectional survey that assessed demographic information, dermatologic history, as well as knowledge, attitude, and behavior factors associated with sunburn. A total of 437 participants whose data were complete for all variables were included in the multivariate analysis. In multivariate logistic regression, younger age (18-29 years) was the most significant predictor of sunburn (OR, 15.26; 95% CI, 5.97-38.98; PSunburn prevention programs that osteopathic physicians can readily implement in clinical practice are urgently needed, particularly for young adult patients. This study identified 7 predictors of sunburn in Florida residents. With additional research findings, promoting attitude change toward sun protection may be a viable strategy.

    To examine the incidence of epistaxis as a function of season and age and to determine predictors of episodes within the epistaxis patient population presenting to a tertiary hospital system. Retrospective cohort study. Electronic medical record charts of patients presenting to the Northwestern Emergency Department, admitted to an inpatient ward, or seen in an outpatient setting between 2008 and 2012 were reviewed and selected for an International Classifications of Disease-Ninth Revision epistaxis code of 784.7. Season of presentation, demographic factors (age, race, gender, insurance status), medication use (including anticoagulants and topical nasal steroid administration), and several comorbidities were analyzed as potential predictors of episodes. A total of 2,405 patients were identified with a total of 3,666 individual epistaxis episodes over 5 years. Multivariate analysis identified allergic rhinitis (AR), chronic sinusitis (CRS), coagulopathy, hereditary hemorrhagic telangiectasia (HHT), hematologic malignancy, and hypertension (HTN) as predictors of a higher number of cases. Epistaxis occurred more frequently during colder months and in older patients. Epistaxis occurs more commonly during the winter and in older patients. AR, CRS, coagulopathy, HHT, hematologic malignancy, and HTN are associated with increased epistaxis incidence. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

    The solvent extraction of lanthanum(III), europium(III), lutetium(III), scandium(III), and indium(III) in 0.1 mol dm -3 sodium nitrate solutions with 2-thenoyltrifluoroacetone (Htta) in the absence and presence of tetrabutylammonium ions (tba + ) into carbon tetrachloride was measured. The extraction of lanthanum(III), europium(III), and lutetium(III) was greatly enhanced by the addition of tba + ; this could be explained in terms of the extraction of a ternary complex, M(tta) 4 - tba + . However, the extractions of scandium(III) and indium(III) were nearly the same when tba + was added. The data were treated on the basis of the formation equilibrium of the ternary complex from the neutral chelate, M(tta) 3 , with the extracted ion-pairs of the reagents, tta - tba + , in the organic phase. It was concluded that the degree of association of M(tta) 3 with the ion-pair, tta - tba + , is greater in the order La(tta) 3 ≅ Eu(tta) 3 > Lu(tta) 3 , or that the stability of the ternary complex in the organic phase is higher in the order La(tta) 4 - tba + ≅ Eu(tta) 4 - tba + > Lu(tta) 4 - tba + . This is similar to those of adduct metal chelates of Htta with tributylphosphate (TBP) in synergistic extraction systems. (author)

    Full Text Available Fue realizada la interpretación de anomalías de potencial espontáneo en dos perfiles norte-sur medidos en el depósito de desechos caseros de Matatlán, Guadalajara, al oeste de México. El sitio se localiza al este de la Ciudad de Guadalajara, sobre un flanco occidental del cañón del Río Grande de Santiago, y se asienta sobre una pequeña meseta densamente fracturada de andesitas basálticas y riolitas. La interpretación se realizó mediante el uso de tres técnicas numéricas. La primera consiste de un modelado analítico basado en el algoritmo de Fournier; en este algoritmo se propone un modelo del subsuelo, que se ha modificado para obtener potenciales ajustando la resistividad de la zona y asumiendo una variación continua hacia profundidad de la intensidad primaria de la fuente. Los dos restantes son técnicas de inversión basadas en los trabajos de DiMaio y Patella, Birch y Hämann et al. Estos convolucionan los datos con una función de barrido que depende de la geometría de la fuente. Todo esto es útil para inferir las fuentes de las anomalías y determinar presencia de estructuras geológicas que pueden corresponder a fallas o fracturas vinculadas con una posible migración de lixiviados. Los resultados exhiben una alta acumulación de lixiviados que ocurren a una profundidad aproximada a los diez metros. El modelado directo muestra variaciones de la elevación de la superficie freática con respecto al nivel medio del mar, mientras que las técnicas de inversión señalan la extensión vertical de un posible flujo vertical de lixiviados en combinación con una extensión lateral. Los resultados de las inversiones de los dos perfiles exhiben el flujo vertical de lixiviados a lo largo de fronteras planas, ilustrando la presencia de algunas posibles fallas con un rumbo NE-SW o W-E. Debido a la naturaleza del sitio y a la calidad de los datos de potencial espontáneo adquiridos, las anomalías medidas se atribuyen a diferentes

    Los depósitos deltaicos del Eoceno de Ager (provincia de Lérida se caracterizan por presentar ciclos a gran escala, formados por alternancias de materiales. pelíticos y cuerpos de areniscas. Estos depósitos están formados, en su sector más occidental, por margas de bahía y lóbulos de frente de canal deltaico. En esta zona, algunos de los tramos pelíticos presentan una marcada ciclicidad, formada por la repetición de dos términos. Uno de ellos es margoso y está bioturbado; el otro es arcilloso y presenta una laminación fina, no distorsionada. Para la caracterización de estos ciclos pelíticos se ha estudiado detalladamente el contenido faunístico, secuencias de estructuras y relaciones laterales de parte de los materiales del "Nivel Intramareal Inferior" (''Tramo Superior" del grupo deposicional Roda-Oroel en el sector comprendido entre el Cementerio de la Régola y el Barranc de Ribellera (Vall d'Ager, Lérida. Los términos margosos son de color ocre y poseen un contenido faunístico atribuible a un "lagoon" con aguas de salinidad normal o ligeramente hipersalinas. Por su parte. las arcillas laminadas apenas tienen fauna y no presentan signos de bioturbación. Su alto contenido en restos vegetales y evaporitas, sugiere que se depositaron en un ambiente reductor, posiblemente anóxico, Teniendo en cuenta el contexto sedimentario, dicha ciclicidad puede corresponder a períodos de inmersión y períodos de estancamiento, por pérdida de conexión con el mar abierto, de una bahía interdistributaria deltaica.

Sin embargo, ese procedimiento es eficaz si se aplica asociado a un método de búsqueda de cladogramas que proscriba la homoplasia, como el principio de compatibilidad. Empleado como método de clasificación, el análisis de parsimonia puede producir resultados ampliamente coincidentes con los de otros procedimientos de jerarquización. Convendría distinguir dos acepciones distintas del análisis de parsimonia aplicado a este tipo de datos, que representan interpretaciones estáticas de los cladogramas de áreas (sensu Rosen, 1988: el PAE en un sentido estricto (para detectar áreas de endemicidad, potencialmente solapadas y por tanto con múltiples soluciones, y la metodología cladística aplicada como método de agrupación (idealmente con una única solución, la de mayor parsimonia.

A prospective cohort study enrolled 261 patients with aneurysmal subarachnoid hemorrhage, attending in Hermanos Ameijeiras Hospital from October 2005, and June 2014. An increased re-bleeding risk in the multivariate analysis was associated with grade III (OR 2.01; 95% CI; 1.06-3.84) and grade IV (OR 3.84; 95% CI; 2.06-7.31) on World Federation Neurological Surgeon (WFNS) scale; grade III (OR 2.04; 95% CI; 1.01-4.13) and grade IV (OR 2.12, 95% CI; 1.05-4.28) on the Fischer scale, aneurism location in posterior circulation (OR 2.45, 95% CI; 1.33-4.44), and anterior communicant artery (OR 1.57, 95% CI;1.00-2.46). Hypertension history was present in 60.9% (159 patients) and was also associated with risk of re-bleeding (OR 2.70, 95% CI; 1.00-7.30). Blood pressure, haematocrit, glycemic, aneurysm size, multiple aneurysms, and location in the middle cerebral artery, do not show any relationship. Hypertension history, poor grade (III and IV) on WFNS and Fisher scale and aneurysm location were independent risks factors of re-bleeding in patients with delayed aneurysmal treatment.

    The aim of this study was to examine which individual and work-related characteristics predict work outcomes related to sustainable employment among male shift and day workers. Between 1 September 2005 and 31 December 2009, data on individual and work-related characteristics of N=5640 employees of Tata Steel in the Netherlands were retrieved from the Occupational Health Service and company registers. Work outcomes related to sustainable employment were (i) temporarily being placed in less strenuous work, (ii) sickness absence ≥6 weeks, and (iii) leaving the organization. Cox proportional hazard analyses were performed for all outcome measures. Similar predictors were found for shift and day workers although some differences were observed. For shift workers, high blood pressure and cardiovascular disease were important predictors for sickness absence. For day workers, insomnia was an important predictor of sickness absence ≥6 weeks. Similar predictors in magnitude and direction were found for work outcomes related to sustainable employment among shift and day workers. Interventions aimed at enhancing sustainable employability should focus on individual and work-related characteristics.

    Following a major burn, skeletal muscle protein synthesis rate increases but is often insufficient to compensate for massively elevated muscle protein breakdown rates. Given the long-term nature of the pathophysiologic response to burn injury, we hypothesized that muscle protein synthesis rate would be chronically elevated in severely burned children. The objectives of this study were to characterize muscle protein synthesis rate of burned children over a period of 24 months after injury and to identify predictors that influence this response. A total of 87 children with 40% or greater total body surface area (TBSA) burned were included. Patients participated in stable isotope infusion studies at 1, 2, and approximately 4 weeks after burn and at 6, 12, and 24 months after injury to determine skeletal muscle protein fractional synthesis rate. Generalized estimating equations with log link normal distribution were applied to account for clustering of patients and control for patient characteristics. Patients (8 ± 6 years) had large (62, 51-72% TBSA) and deep (47% ± 21% TBSA third degree) burns. Muscle protein fractional synthesis rate was elevated throughout the first 12 months after burn compared with established values from healthy young adults. Muscle protein fractional synthesis rate was lower in boys, in children older than 3 years, and when burns were greater than 80% TBSA. Muscle protein synthesis is elevated for at least 1 year after injury, suggesting that greater muscle protein turnover is a component of the long-term pathophysiologic response to burn trauma. Muscle protein synthesis is highly affected by sex, age, and burn size in severely burned children. These findings may explain the divergence in net protein balance and lean body mass in different populations of burn patients. Prognostic study, level III.

    The lack of potent integrated light emitters is one of the bottlenecks that have so far hindered the silicon photonics platform from revolutionizing the communication market. Photonic circuits with integrated light sources have the potential to address a wide range of applications from short-distance data communication to long-haul optical transmission. Notably, the integration of lasers would allow saving large assembly costs and reduce the footprint of optoelectronic products by combining photonic and microelectronic functionalities on a single chip. Since silicon and germanium-based sources are still in their infancy, hybrid approaches using III-V semiconductor materials are currently pursued by several research laboratories in academia as well as in industry. In this paper we review recent developments of hybrid III-V/silicon lasers and discuss the advantages and drawbacks of several integration schemes. The integration approach followed in our laboratory makes use of wafer-bonded III-V material on structured silicon-on-insulator substrates and is based on adiabatic mode transfers between silicon and III-V waveguides. We will highlight some of the most interesting results from devices such as wavelength-tunable lasers and AWG lasers. The good performance demonstrates that an efficient mode transfer can be achieved between III-V and silicon waveguides and encourages further research efforts in this direction.

    C5-BPP is a highly efficient N-donor ligand for the separation of trivalent actinides, An(iii), from trivalent lanthanides, Ln(iii). The molecular origin of the selectivity of C5-BPP and many other N-donor ligands of the BTP-type is still not entirely understood. We present here the first NMR studies on C5-BPP Ln(iii) and An(iii) complexes. C5-BPP is synthesized with 10% 15 N labeling and characterized by NMR and LIFDI-MS methods. 15 N NMR spectroscopy gives a detailed insight into the bonding of C5-BPP with lanthanides and Am(iii) as a representative for trivalent actinide cations, revealing significant differences in 15 N chemical shift for coordinating nitrogen atoms compared to Ln(iii) complexes. The temperature dependence of NMR chemical shifts observed for the Am(iii) complex indicates a weak paramagnetism. This as well as the observed large chemical shift for coordinating nitrogen atoms show that metal-ligand bonding in Am(C5-BPP) 3 has a larger share of covalence than in lanthanide complexes, confirming earlier studies. The Am(C5-BPP) 3 NMR sample is furthermore spiked with Cm(iii) and characterized by time-resolved laser fluorescence spectroscopy (TRLFS), yielding important information on the speciation of trace amounts of minor complex species.

    The increase in sensitivity and selectivity of reactions in which colored species are formed by the addition of different metal ions is an area of research that has recently been developed. This phenomenon, which is sometimes called cocolaration effect, has been explained by the formation of mixed metal complex. The authors found an analogous phenomenon of reactions forming fluorescent complexes. The complexes of Sm(III)-thenoyltrifluoroacetone (TTA)-phenanthroline (Phen)-Triton-X-100 (TX-100) and Gd(III) (or La(III), Lu(III) and Y(III))-TTA-Phen-TX-100 had practically no fluorescence separately. Instead, a fluorescence-enhancement phenomenon caused by adding Gd or La, Lu and Y ions to the system was observed for the first time. The intensity of the enhanced fluorescence of Sm(III) complex was increased in the following order: La< Y< Lu< Gd. By analogy with cocoloration effect, the authors call this new fluorescence-enhancement phenomenon the co-fluorescence effect. The object of this work was to study the enhancement effect of Gd(III) on the fluorescence of the Sm(III)-TTA-Phen-TX-100 system. The recommended fluorimetric method has been applied to the determination of trace amounts of samarium in ytterbium oxide with satisfactory results. A general reaction mechanism for the system studied was proposed

Using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines for the literature reviewed, 77 published studies or doctoral dissertations completed between 1990 and 2012 met the inclusion criteria. Eleven predictors of hope were identified and each predictor in relation to hope was subjected to meta-analysis. Five predictors (positive affect, life satisfaction, optimism, self-esteem, and social support) of hope had large mean ESs, 1 predictor (depression) had a medium ES, 4 predictors (negative affect, stress, academic achievement, and violence) had small ESs, and 1 predictor (gender) had a trivial ES. Findings are interpreted for the 11 predictors in relation to hope. Limitations and conclusions are addressed; future studies are recommended. © The Author(s) 2014.

    The aim of this review was to determine the clinical and biological predictors of the ketamine response. A systematic research on PubMed and PsycINFO database was performed without limits on year of publication. The main predictive factors of ketamine response, which were found in different studies, were (i) a family history of alcohol dependence, (ii) unipolar depressive disorder, and (iii) neurocognitive impairments, especially a slower processing speed. Many other predictive factors were identified, but not replicated, such as personal history of alcohol dependence, no antecedent of suicide attempt, anxiety symptoms. Some biological factors were also found such as markers of neural plasticity (slow wave activity, brain-derived neurotrophic factor Val66Met polymorphism, expression of Shank 3 protein), other neurologic factors (anterior cingulate activity, concentration of glutamine/glutamate), inflammatory factors (IL-6 concentration) or metabolic factors (concentration of B12 vitamin, D- and L-serine, alterations in the mitochondrial β-oxidation of fatty acids). This review had several limits: (i) patients had exclusively resistant major depressive episodes which represent a sub-type of depression and not all depression, (ii) response criteria were more frequently assessed than remission criteria, it was therefore difficult to conclude that these predictors were similar, and finally (iii) many studies used a very small number of patients. In conclusion, this review found that some predictors of ketamine response, like basal activity of anterior cingulate or vitamin B12 concentration, were identical to other therapeutics used in major depressive episode. These factors could be more specific to the major depressive episode and not to the ketamine response. Others, like family history of alcohol dependence, body mass index, or D- and L-serine were different from the other therapeutics. Neurocognitive impairments like slower speed processing or alterations in

    The PISC III Actions are intended to extend the results and methodologies of the previous PISC excercises, i.e. the validation of the capabilities of the various examination techniques when used on real defects in real components under real conditions of inspection. Being aware of the important safety role that steam generator tubes play as barrier between primary and secondary cooling system and of the industrial problems that the degradation of these tubes can create, the PISC III Management Board agreed to include in the PISC III Programme a special Action on Steam Generator Tubes Testing (SGT). It was decided to organize the programme in three phases, including Round Robin Tests (RRT): - capability tests on loose tubes, - capability tests on transportable mock-ups, - reliability tests on fixed mock-ups including some interesting SURRY tubes

    Full Text Available Walking, more specifically gait, is an essential component of daily living. Walking is a very different activity for individuals with a Body Mass Index (BMI of 40 or more (Class III obesity compared with those who are overweight or obese with a BMI between 26–35. Yet all obesity weight classes receive the same physical activity guidelines and recommendations. This observational study examined the components of function and disability in a group with Class III obesity and a group that is overweight or has Class I obesity. Significant differences were found between the groups in the areas of gait, body size, health condition, and activity capacity and participation. The Timed Up and Go test, gait velocity, hip circumference, and stance width appear to be most predictive of activity capacity as observed during gait assessment. The findings indicate that Class III-related gait is pathologic and not a normal adaptation.

    Poor sanitation, including the lack of clean functioning toilets, is a major factor contributing to morbidity and mortality from infectious diseases in the developing world. We examine correlates of latrine ownership in rural India with a focus on social network predictors. Participants from 75 villages provided the names of their social contacts as well as their own relevant demographic and household characteristics. Using these measures, we test whether the latrine ownership of an individual's social contacts is a significant predictor of individual latrine ownership. We also investigate whether network centrality significantly predicts latrine ownership, and if so, whether it moderates the relationship between the latrine ownership of the individual and that of her social contacts. Our results show that, controlling for the standard predictors of latrine ownership such as caste, education, and income, individuals are more likely to own latrines if their social contacts own latrines. Interaction models suggest that this relationship is stronger among those of the same caste, the same education, and those with stronger social ties. We also find that more central individuals are more likely to own latrines, but the correlation in latrine ownership between social contacts is strongest among individuals on the periphery of the network. Although more data is needed to determine how much the clustering of latrine ownership may be caused by social influence, the results here suggest that interventions designed to promote latrine ownership should consider focusing on those at the periphery of the network. The reason is that they are 1) less likely to own latrines and 2) more likely to exhibit the same behavior as their social contacts, possibly as a result of the spread of latrine adoption from one person to another.

    Full Text Available Background Understanding risk factors that increase readmission rates may help enhance patient education and set system-wide expectations. We aimed to provide benchmark data on causes and predictors of readmission following inpatient plastic surgery. Methods The 2011 National Surgical Quality Improvement Program dataset was reviewed for patients with both "Plastics" as their recorded surgical specialty and inpatient status. Readmission was tracked through the "Unplanned Readmission" variable. Patient characteristics and outcomes were compared using chi-squared analysis and Student's t-tests for categorical and continuous variables, respectively. Multivariate regression analysis was used for identifying predictors of readmission. Results A total of 3,671 inpatient plastic surgery patients were included. The unplanned readmission rate was 7.11%. Multivariate regression analysis revealed a history of chronic obstructive pulmonary disease (COPD (odds ratio [OR], 2.01; confidence interval [CI], 1.12-3.60; P=0.020, previous percutaneous coronary intervention (PCI (OR, 2.69; CI, 1.21-5.97; P=0.015, hypertension requiring medication (OR, 1.65; CI, 1.22-2.24; P<0.001, bleeding disorders (OR, 1.70; CI, 1.01-2.87; P=0.046, American Society of Anesthesiologists (ASA class 3 or 4 (OR, 1.57; CI, 1.15-2.15; P=0.004, and obesity (body mass index ≥30 (OR, 1.43; CI, 1.09-1.88, P=0.011 to be significant predictors of readmission. Conclusions Inpatient plastic surgery has an associated 7.11% unplanned readmission rate. History of COPD, previous PCI, hypertension, ASA class 3 or 4, bleeding disorders, and obesity all proved to be significant risk factors for readmission. These findings will help to benchmark inpatient readmission rates and manage patient and hospital system expectations.

    1999-05-01

    An analytic thermophysical property model using general function forms is developed for a reactor safety analysis code, SIMMER-III. The function forms are designed to represent correct behavior of properties of reactor-core materials over wide temperature ranges, especially for the thermal conductivity and the viscosity near the critical point. The most up-to-date and reliable sources for uranium dioxide, mixed-oxide fuel, stainless steel, and sodium available at present are used to determine parameters in the proposed functions. This model is also designed to be consistent with a SIMMER-III model on thermodynamic properties and equations of state for reactor-core materials. (author)

    ROSA-III experiment with the simulated BWR system is to investigate thermal hydraulic behavior as well as ECCS performance in a postulated loss-of-coolant accident. RUN 701 assumes average core power, high and low pressure core sprays and low pressure injection of ECCS. Prediction of experiment RUN 701 was made with computer code RELAP-4J. The results indicate the need for ROSA-III pump characteristics to be clarified and for liquid level formation model to be improved. Comparison of the prediction results with the experimental data should reveal the areas of modifications in calculation model. (auth.)

    The CLEO III group is constructing a new chamber to be installed as part of the staged luminosity upgrade program at the Cornell electron storage ring and compatible with the interaction region optics. Although having less radial extent than the current CLEO II tracking system, CLEO III will have equivalent momentum resolution because of material reduction in the drift chamber inner skin and gas. The thin inner skin requires special attention to the end-plate motion due to wire creep. During stringing, use of a robot will fully automate the wire handling on the upper end. (author)

    The current research evaluated the continuity between DSM-5 Section II and Section III diagnostic operationalizations of avoidant personality disorder (AvPD). More specifically, the study had three aims: (1) to examine which personality constructs comprise the optimal trait constellation for AvPD; (2) to investigate the utility of the proposed structure of the Section III AvPD diagnosis, in regard to combining functional impairment (criterion A) and a dimensional measure of personality (criterion B) variables; and (3) to determine whether AvPD-specific impairment confers incremental meaningful contribution above and beyond general impairment in personality functioning. A mixed sample of 402 university and community participants was recruited, and they were administered multiple measures of Section II PD, personality traits, and personality impairment. A latent measurement model approach was used to analyse data. Results supported the general continuity between Section II and Section III of the DSM-5; however, three of the four main criterion B traits were the stronger predictors. There was also some support for the trait unassertiveness augmenting the criterion B trait profile. The combination of using functional impairment criteria (criterion A) and dimensional personality constructs (criterion B) in operationalizing AvPD was supported; however, the reliance of disorder-specific over general impairment for criterion A was not supported.

    The formation of chloro, bromo and iodo complexes of yttrium(III), and bromo and iodo complexes of lanthanum(III), neodymium(III), terbium(III) and thulium(III) has been studied by precise titration calorimetry in N,N-dimethylformamide (DMF) at 25 o C. The formation of [YCl] 2+ , [YCl 2 ] + , [YCl 3 ] and [YCl 4 ] - , and [MBr] 2+ and [MBr 2 ] + (M = Y, La, Nd, Tb, Tm) was revealed, and their formation constants, enthalpies and entropies were determined. It is found that the formation enthalpies change in the sequence ΔH o (Cl) > ΔH o (l), which is unusual for hard metal (III) ions. This implies that, unlike the chloride ion, the bromide ion forms outer-sphere complexes with the lanthanide(III) and yttrium(III) ions in DMF. Evidence for either an inner- or outer-sphere complex was obtained from 89 Y NMR spectra for Y(ClO 4 ) 3 , YCl 3 and YBr 3 DMF solutions at room temperature. (author)

    Laser-induced fluorescence (LIF) studies of Sm(III) and Cm(III) complexes in the NaSCN/DHDECMP solvent extraction system were carried out. Luminescence lifetimes were measured to determine the number of water molecules coordinated to Sm(III), Tb(III), Dy(III), and Cm(III) in the sodium thiocyanate solution and in the DHDECMP phase. The hydration number of Sm(III), Tb(III), Dy(III), and Cm(III) in the sodium thiocyanate solution decreased linearly with increasing sodium thiocyanate concentration. The hydration numbers of Sm(III), Dy(III), and Cm(III) in the DHDECMP phase decreased with increasing sodium thiocyanate concentration. The water molecules in the inner coordination sphere of Sm(III) and Dy(III) extracted into the DHDECMP were not completely removed at low sodium thiocyanate concentration but decreased with increasing sodium thiocyanate concentration. However, in the case of Cm(III) extracted into the DHDECMP phase from the sodium thiocyanate solution, there was no water in the inner coordination sphe...

  2. Predictors of tonic immobility during traumatic events

    Directory of Open Access Journals (Sweden)

    Arturo Bados

    2015-10-01

    Full Text Available Tonic immobility (TI is a possible reaction to danger that is facilitated by intense fear, physical restraint and perceived inability to escape. Other variables that could affect TI, such as the type and characteristics of traumatic events and personal characteristics have been little or no studied. The present study evaluated the power of these variables to predict TI in a sample of 273 college students who had experienced at least one traumatic event. Of the sample, 7.7% and 13.2% responded with TI according to the two stricter definitions adopted. Most of the variables were significantly associated with TI in univariate analyses. However, in a multiple regression analysis, only certain features of the events (occurrence of physical/sexual abuse, number of different types of events experienced and certain reactions to them (perception of how traumatic were the events, severe fear response were significant predictors of TI. Since these predictors explained only 25% of the variance, the influence of other variables -such as neuroticism, negative affectivity and perceived lack of personal control or resources to cope with traumatic events- should be investigated.

    We perform a cosmological simulation in order to model the growth and evolution of Population III (Pop III) stellar systems in a range of host minihalo environments. A Pop III multiple system forms in each of the ten minihaloes, and the overall mass function is top-heavy compared to the currently observed initial mass function in the Milky Way. Using a sink particle to represent each growing protostar, we examine the binary characteristics of the multiple systems, resolving orbits on scales as small as 20 AU. We find a binary fraction of approx. 36, with semi-major axes as large as 3000 AU. The distribution of orbital periods is slightly peaked at approx. < 900 yr, while the distribution of mass ratios is relatively flat. Of all sink particles formed within the ten minihaloes, approx. 50 are lost to mergers with larger sinks, and 50 of the remaining sinks are ejected from their star-forming disks. The large binary fraction may have important implications for Pop III evolution and nucleosynthesis, as well as the final fate of the first stars.

  15. Effects upon metabolic pathways and energy production by Sb(III and As(III/Sb(III-oxidase gene aioA in Agrobacterium tumefaciens GW4.

    Directory of Open Access Journals (Sweden)

    Jingxin Li

    Full Text Available Agrobacterium tumefaciens GW4 is a heterotrophic arsenite [As(III]/antimonite [Sb(III]-oxidizing strain. The As(III oxidase AioAB is responsible for As(III oxidation in the periplasm and it is also involved in Sb(III oxidation in Agrobacterium tumefaciens 5A. In addition, Sb(III oxidase AnoA and cellular H2O2 are also responsible for Sb(III oxidation in strain GW4. However, the deletion of aioA increased the Sb(III oxidation efficiency in strain GW4. In the present study, we found that the cell mobility to Sb(III, ATP and NADH contents and heat release were also increased by Sb(III and more significantly in the aioA mutant. Proteomics and transcriptional analyses showed that proteins/genes involved in Sb(III oxidation and resistance, stress responses, carbon metabolism, cell mobility, phosphonate and phosphinate metabolism, and amino acid and nucleotide metabolism were induced by Sb(III and were more significantly induced in the aioA mutant. The results suggested that Sb(III oxidation may produce energy. In addition, without periplasmic AioAB, more Sb(III would enter bacterial cells, however, the cytoplasmic AnoA and the oxidative stress response proteins were significantly up-regulated, which may contribute to the increased Sb(III oxidation efficiency. Moreover, the carbon metabolism was also activated to generate more energy against Sb(III stress. The generated energy may be used in Sb transportation, DNA repair, amino acid synthesis, and cell mobility, and may be released in the form of heat.

    CONTEXT Accurate prediction of who will (or won’t) have high probability of survival benefit from standard treatments is fundamental for individualized cancer treatment strategies. OBJECTIVE To develop a predictor of response and survival from chemotherapy for newly diagnosed invasive breast cancer. DESIGN Development of different predictive signatures for resistance and response to neoadjuvant chemotherapy (stratified according to estrogen receptor (ER) status) from gene expression microarrays of newly diagnosed breast cancer (310 patients). Then prediction of breast cancer treatment-sensitivity using the combination of signatures for: 1) sensitivity to endocrine therapy, 2) chemo-resistance, and 3) chemo-sensitivity. Independent validation (198 patients) and comparison with other reported genomic predictors of chemotherapy response. SETTING Prospective multicenter study to develop and test genomic predictors for neoadjuvant chemotherapy. PATIENTS Newly diagnosed HER2-negative breast cancer treated with chemotherapy containing sequential taxane and anthracycline-based regimens then endocrine therapy (if hormone receptor-positive). MAIN OUTCOME MEASURES Distant relapse-free survival (DRFS) if predicted treatment-sensitive and absolute risk reduction (ARR, difference in DRFS of the two predicted groups) at median follow-up (3 years), and their 95% confidence intervals (CI). RESULTS Patients in the independent validation cohort (99% clinical Stage II–III) who were predicted to be treatment-sensitive (28% of total) had DRFS of 92% (CI 85–100) and survival benefit compared to others (absolute risk reduction (ARR) 18%; CI 6–28). Predictions were accurate if breast cancer was ER-positive (30% predicted sensitive, DRFS 97%, CI 91–100; ARR 11%, CI 0.1–21) or ER-negative (26% predicted sensitive, DRFS 83%, CI 68–100; ARR 26%, CI 4–28), and were significant in multivariate analysis after adjusting for relevant clinical-pathologic characteristics.

    Two methods for predicting remissions in obsessive-compulsive disorder (OCD) treatment are evaluated. Y-BOCS measurements of 88 patients with a primary OCD (DSM-III-R) diagnosis were performed over a 16-week treatment period, and during three follow-ups. Remission at any measurement was defined as a Y-BOCS score lower than thirteen combined with a reduction of seven points when compared with baseline. Logistic regression models were compared with a Cox regression for recurrent events model. Logistic regression yielded different models at different evaluation times. The recurrent events model remained stable when fewer measurements were used. Higher baseline levels of neuroticism and more severe OCD symptoms were associated with a lower chance of remission, early age of onset and more depressive symptoms with a higher chance. Choice of outcome time affects logistic regression prediction models. Recurrent events analysis uses all information on remissions and relapses. Short- and long-term predictors for OCD remission show overlap.

    Phase III randomized controlled trials (RCT) in oncology fail to lead to registration of new therapies more often than RCTs in other medical disciplines. Most RCTs are sponsored by the pharmaceutical industry, which reflects industry's increasing responsibility in cancer drug development. Many preclinical models are unreliable for evaluation of new anticancer agents, and stronger evidence of biologic effect should be required before a new agent enters the clinical development pathway. Whenever possible, early-phase clinical trials should include pharmacodynamic studies to demonstrate that new agents inhibit their molecular targets and demonstrate substantial antitumor activity at tolerated doses in an enriched population of patients. Here, we review recent RCTs and found that these conditions were not met for most of the targeted anticancer agents, which failed in recent RCTs. Many recent phase III RCTs were initiated without sufficient evidence of activity from early-phase clinical trials. Because patients treated within such trials can be harmed, they should not be undertaken. The bar should also be raised when making decisions to proceed from phase II to III and from phase III to marketing approval. Many approved agents showed only better progression-free survival than standard treatment in phase III trials and were not shown to improve survival or its quality. Introduction of value-based pricing of new anticancer agents would dissuade the continued development of agents with borderline activity in early-phase clinical trials. When collaborating with industry, oncologists should be more critical and better advocates for cancer patients. ©2015 American Association for Cancer Research.

    The Sandia Pulsed Reactor III (SPR III) is a fast-pulse research reactor which was designed and built at Sandia Laboratories and achieved criticality in August 1975. The reactor is now characterized and is in an operational configuration. The core consists of 18 fuel plates (258 kg fuel mass) of fully enriched uranium alloyed with 10 wt.% molybdenum. It is arranged in an annular configuration with an inside diameter of 17.78 cm, an outside diameter of 29.72 cm, and a height of 35.9 cm. The reactor core uses reflectors of copper and aluminum for control and an external bolting arrangement to secure the fuel plates. SPR III and SPR II are operated on an interchangeable basis using the same facility and control system. As of June 1977, SPR III has had over 240 operations with core temperatures up to 541 0 C

    The preparation and characterization of addition compounds between lanthanide (III) and yttrium (III) picrates and tetra methylene sulfoxide as ligand were described. The adducts were prepared in the molar relation 1 (salt): 3(ligand) in ethanol. They are microcrystalline with more intense color than those of their respective hydrated salts. At room temperature conditions they are non hygroscopic and do not present perceptible alterations. They became slightly opalescent, when heated between 363 and 423 K. At higher temperatures under several heating ratios, the behavior shown is the same: melting between 439 and 472 K. The characterization of the compounds was made by elemental analysis, electrolytic conductance measurements, X-ray powder patterns, infrared spectroscopy, visible electronic absorption and emission spectra of the neodymium (III) and europium (III), respectively.

    Full Text Available Is physiological performance a suitable proxy of fitness in plants? Although, several studies have been conducted to measure some fitness-related traits and physiological performance, direct assessments are seldom found in the literature. Here, we assessed the physiology-fitness relationship using second-generation individuals of the invasive plant species Taraxacum officinale from 17 localities distributed in five continents. Specifically, we tested if i the maximum quantum yield is a good predictor for seed-output ii whether this physiology-fitness relationship can be modified by environmental heterogeneity, and iii if this relationship has an adaptive consequence for T. officinale individuals from different localities. Overall, we found a significant positive relationship between the maximum quantum yield and fitness for all localities evaluated, but this relationship decreased in T. officinale individuals from localities with greater environmental heterogeneity. Finally, we found that those individuals from localities where environmental conditions are highly seasonal performed better under heterogeneous environmental conditions. Contrarily, under homogeneous controlled conditions, those individuals from localities with low environmental seasonality performed much better. In conclusion, our results suggest that the maximum quantum yield seem to be good predictors for plant fitness. We suggest that rapid measurements, such as those obtained from the maximum quantum yield, could provide a straightforward proxy of individual's fitness in changing environments.

  4. Spontaneous eye blink rate as predictor of dopamine-related cognitive function-A review.

    2016-12-01

    An extensive body of research suggests the spontaneous eye blink rate (EBR) is a non-invasive indirect marker of central dopamine (DA) function, with higher EBR predicting higher DA function. In the present review we provide a comprehensive overview of this literature. We broadly divide the available research in studies that aim to disentangle the dopaminergic underpinnings of EBR, investigate its utility in diagnosis of DA-related disorders and responsivity to drug treatment, and, lastly, investigate EBR as predictor of individual differences in DA-related cognitive performance. We conclude (i) EBR can reflect both DA receptor subtype D1 and D2 activity, although baseline EBR might be most strongly related to the latter, (ii) EBR can predict hypo- and hyperdopaminergic activity as well as normalization of this activity following treatment, and (iii) EBR can reliably predict individual differences in performance on many cognitive tasks, in particular those related to reward-driven behavior and cognitive flexibility. In sum, this review establishes EBR as a useful predictor of DA in a wide variety of contexts. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The ACCOMPLISH Trial investigated intensive antihypertensive combination treatment with benazepril + amlodipine (B+A) or benazepril + hydrochlorothiazide (B+H) on cardiovascular outcomes in patients with systolic hypertension. We analyzed the baseline predictors of achieving a systolic blood pressure (SBP) Nordic region) and Caucasian ethnicity in both randomization arms. A higher diastolic BP and the use of lipid lowering agents indicated favorable effects in the B+H arm only. The predictors of uncontrolled SBP were: (i) higher baseline SBP values, (ii) higher number of previous antihypertensive medications in both arms, (iii) the previous use of insulin in the B+A arm, and (iv) pre-trial calcium channel blocker (CCB) use in the B+H arm. Additionally, pre-trial use of thiazides and electrocardiogram (ECG)-left ventricular hypertrophy (LVH) at baseline predicted higher, and smoking lower absolute SBP in the B+A arm and the use of thiazides and proteinuria a higher SBP in the B+H arm. Irrespective of treatment, patients in the USA and Caucasians achieved better SBP control, whereas higher baseline SBP and more previous antihypertensive medications indicated less control. Concomitant use of lipid lowering treatment indicated a better SBP control in the benazepril + hydrochlorothiazide arm. Lastly, insulin use and ECG-LVH in the benazepril + amlodipine arm and proteinuria in the benazepril + hydrochlorothiazide arm indicated poor control.

    Purpose: To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer. Methods and Materials: The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log–rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

    Objectives: We sought to examine whether a posterior distribution of white matter hyperintensities (WMH) is an independent predictor of pathologically confirmed cerebral amyloid angiopathy (CAA) and whether it is associated with MRI markers of CAA, in patients without lobar intracerebral hemorrhage. Methods: We developed a quantitative method to measure anteroposterior (AP) distribution of WMH. A retrospective cohort of patients without intracerebral hemorrhage and with pathologic evaluation of CAA was examined to determine whether posterior WMH distribution was an independent predictor of CAA (n = 59). The relationship of AP distributions of WMH to strictly lobar microbleeds (MBs) (n = 259) and location of dilated perivascular spaces (DPVS) (n = 85) was examined in a separate cohort of patients evaluated in a memory clinic. Results: A more posterior WMH distribution was found to be an independent predictor of pathologic evidence of CAA (p = 0.001, odds ratio [95% confidence interval] = 1.19 [1.07–1.32]), even in the subgroup without lobar MBs (p = 0.016, odds ratio [95% confidence interval] = 1.18 [1.03–1.36]). In the memory clinic cohort, strictly lobar MBs were independently associated with more posterior WMH distribution (p = 0.009). AP distribution of WMH was also associated with location of DPVS (p = 0.001), in that patients with predominant DPVS in the white matter over the basal ganglia harbored a more posterior WMH distribution. Conclusions: Our results suggest that AP distribution of WMH may represent an additional marker of CAA, irrespective of the presence of lobar hemorrhages. Classification of evidence: This study provides Class III evidence that there is a significant association between the AP distribution of WMH on MRI with the presence of pathologically confirmed CAA pathology.

    To determine whether the presence of nasal flaring is a clinical sign of severity and a predictor of hospital mortality in emergency patients with dyspnea. Prospective, observational, single-center study. We enrolled patients older than 15 years of age who required attention for dyspnea categorized as level II or III emergencies according to the Andorran Medical Triage system. Two observers evaluated the presence of nasal flaring. We recorded demographic and clinical variables, including respiratory effort, vital signs, arterial blood gases, and clinical course (hospital admission and mortality). Bivariable analysis was performed and multivariable logistic regression models were constructed. We enrolled 246 patients with a mean (SD) age of 77 (13) years; 52% were female. Nasal flaring was present in 19.5%. Patients with nasal flaring had triage levels indicating greater severity and they had more severe tachypnea, worse oxygenation, and greater acidosis and hypercapnia. Bivariable analysis detected that the following variables were associated with mortality: age (odds ratio [OR], 1.05; 95% CI, 1.01-1.10), prehospital care from the emergency medical service (OR, 3.97; 95% CI, 1.39-11.39), triage level II (OR, 4.19; 95% CI, 1.63-10.78), signs of respiratory effort such as nasal flaring (OR, 3.79; 95% CI, 1.65-8.69), presence of acidosis (OR, 7.09; 95% CI, 2.97-16.94), and hypercapnia (OR, 2.67; 95% CI, 1,11-6,45). The factors that remained independent predictors of mortality in the multivariable analysis were age, severity (triage level), and nasal flaring. In patients requiring emergency care for dyspnea, nasal flaring is a clinical sign of severity and a predictor of mortality.

    Chronic peripheral neuropathy is a major adverse response to oxaliplatin-containing chemotherapy regimens, but there are no established risk factors pertaining to it. We investigated the efficacy of hyperacute peripheral neuropathy (HAPN) as a predictor of oxaliplatin-induced persistent peripheral neuropathy (PPN). Forty-seven cases of stage III colorectal cancer who received adjuvant chemotherapy with oxaliplatin after curative surgery between January 2010 and August 2014 were retrospectively reviewed. HAPN was defined as acute peripheral neuropathy (APN) occurring on day 1 (≤24 h after oxaliplatin infusion) of the first cycle. PPN was defined as neuropathy lasting >1 year after oxaliplatin discontinuation. The average total dose of oxaliplatin was 625.8 mg/m 2 , and the average relative dose intensity was 66.7%. Twenty-two of the 47 patients (46.8%) had PPN and 13 (27.7%) had HAPN. Male sex, treatment for neuropathy, HAPN, and APN were significantly more frequent in patients with PPN (p = 0.013, 0.02, <0.001, and 0.023, respectively). There was no significant difference in the total oxaliplatin dose between patients with and without PPN (p = 0.061). Multivariate analyses revealed total dose of oxaliplatin and HAPN as independent predictors of PPN [p = 0.015; odds ratio (OR) = 1.005, 95% confidence interval (CI), 1.001-1.009 and p = 0.001; OR = 75.307, 5.3-1070.123, respectively]. The total dose of oxaliplatin was relatively lower in patients with HAPN than that in those without HAPN in the PPN-positive group (not significant, p = 0.068). HAPN was found to be a predictor of oxaliplatin-induced PPN.

    Synthetic metalloporphyrins, in the presence of monooxygen donors, are known to mimetize various reactions of cytochrome P450 enzymes systems in the oxidation of drugs and natural products. The oxidation of piperine and piplartine by iodosylbenzene using iron(III) and manganese(III) porphyrins yielded mono- and dihydroxylated products, respectively. Piplartine showed to be a more reactive substrate towards the catalysts tested. The structures of the oxidation products were proposed based on electrospray ionization tandem mass spectrometry.

    2006-01-01

    The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Specifically, sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (1) locally weighted regression (LOESS), (2) additive models, (3) projection pursuit regression, and (4) recursive partitioning regression. The indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility (i.e., the Waste Isolation Pilot Plant). As shown by the example illustrations, the use of smoothing procedures based on nonparametric regression techniques can yield more informative sensitivity analysis results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and model predictions are present

    The heteroscedasticity or changing variance observed ``raw`` data may be the result of randomness or uncertainty in the predictor variables. As an example we consider ``Charpy Test`` experiments widely used to characterize the ductile-brittle toughness of steels such as those used for nuclear pressure vessels. While this type of experiment is of interest in itself, our main objective is to show that the use of a proper statistical technique may help to avoid the use of more complicated physical models to explain the heteroscedasticity of the observations. We also extend the existing method of regression analysis with errors in controllable variables to the case when the variances of the response and the controllable variables are both unknown.

    Researchers have made productive use of Bandura's (1991) construct of moral disengagement (MD) to help explain why sport participants deviate from ethical ideals. In this study of intercollegiate athletes from diverse sports (N = 713), we examined MD in relation to other character-related variables: empathy, moral identity, moral attentiveness, and contesting orientations. We also examined whether moral attentiveness conforms to the pattern of "bracketed morality" found in moral reasoning (Shields & Bredemeier, 1995) and moral behavior (Kavussanu, Boardley, Sagar, & Ring, 2013). Results indicated that MD correlated positively with perceptual moral attentiveness and war contesting orientation; MD correlated negatively with empathy, moral identity, reflective moral attentiveness, and partnership contesting orientation. Results of hierarchical regression demonstrated that gender, contesting orientations, moral identity, and one form of moral attentiveness were significant predictors of MD. Finally, sport participants were found to be less morally attentive in sport than in everyday life.

    2009-01-01

    Interest in sports concussion has grown widely in the last two decades among laypersons and medical professionals. Significant contributions of evidence-based research have led to a better understanding of this multifaceted, but still often elusive, injury. This information has transformed all aspects of concussion management, from on-field evaluation through return-to-play guidelines. The aim of this article is to highlight important research regarding predictors of outcome and treatment protocols. This research has been the basis of the paradigm shift from traditional concussion grading scales to individualized care. Today, concussion management requires a patient-centered approach with individualized assessment, including risk factor analysis, neurocognitive testing, and a thorough symptom evaluation.

    2015-01-01

    INTRODUCTION: Elite athletes frequently experience asthma and airway hyperresponsiveness (AHR). We aimed to investigate predictors of airway pathophysiology in a group of unselected elite summer-sport athletes, training for the summer 2008 Olympic Games, including markers of airway inflammation......, systemic inflammation, and training intensity. METHODS: Fifty-seven Danish elite summer-sport athletes with and without asthma symptoms all gave a blood sample for measurements of high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor alpha (TNF....... In these subjects, no association was found between the levels of AHR to mannitol and methacholine (r = 0.032, P = 0.91). CONCLUSION: AHR in elite athletes is related to the amount of weekly training and the level of serum TNF-α. No association was found between the level of AHR to mannitol and methacholine...

    2006-08-01

    The use of multiple predictor smoothing methods in sampling-based sensitivity analyses of complex models is investigated. Specifically, sensitivity analysis procedures based on smoothing methods employing the stepwise application of the following nonparametric regression techniques are described: (1) locally weighted regression (LOESS), (2) additive models, (3) projection pursuit regression, and (4) recursive partitioning regression. The indicated procedures are illustrated with both simple test problems and results from a performance assessment for a radioactive waste disposal facility (i.e., the Waste Isolation Pilot Plant). As shown by the example illustrations, the use of smoothing procedures based on nonparametric regression techniques can yield more informative sensitivity analysis results than can be obtained with more traditional sensitivity analysis procedures based on linear regression, rank regression or quadratic regression when nonlinear relationships between model inputs and model predictions are present.

    Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.

    The present study focused on the motivational predictors of coping with academic examination through the test of the contribution of self-determination for academic studies and achievement goals. Coping strategies, academic motivation and achievement goals were assessed among 199 undergraduate students. Regression analysis revealed that problem-focused coping is positively predicted by identified regulation and negatively by amotivation, whereas emotion-focused coping is positively predicted by introjected regulation and amotivation. Mastery approach goals contributed positively to problem-focused coping. Identified regulation and mastery approach goals made a unique positive contribution to problem-focused coping, and amotivation was negatively related. Students' coping actions may vary according to both the reasons why they engage in academic studies and the goals they pursue in this setting.

    Mobile phone use is banned or illegal under certain circumstances and in some jurisdictions. Nevertheless, some people still use their mobile phones despite recognized safety concerns, legislation, and informal bans. Drawing potential predictors from the addiction literature, this study sought to predict usage and, specifically, problematic mobile phone use from extraversion, self-esteem, neuroticism, gender, and age. To measure problem use, the Mobile Phone Problem Use Scale was devised and validated as a reliable self-report instrument, against the Addiction Potential Scale and overall mobile phone usage levels. Problem use was a function of age, extraversion, and low self-esteem, but not neuroticism. As extraverts are more likely to take risks, and young drivers feature prominently in automobile accidents, this study supports community concerns about mobile phone use, and identifies groups that should be targeted in any intervention campaigns.

    2016-12-01

    We examined predictors of media multitasking in Chinese adolescents from 3 contexts: characteristics of the media user, types of media use and family media contexts. Three hundred and twenty adolescents, 11-18 years of age, completed questionnaires to measure media use, impulsivity, sensation seeking, time management disposition and family media environment. The results showed that media multitasking was positively correlated with age and total media use time. Participants with high levels of impulsivity and sensation seeking reported more multitasking behaviour. Multitasking was negatively correlated with time management. Children from media-oriented families often engage in more multitasking. What's more, social networking sites use and music use can mediate the effect of individual and family factors on media multitasking. © 2015 International Union of Psychological Science.

    The aim of this study was to identify sociodemographic and clinical predictors of excellent response, that is, 'cure' of future affective episodes, to lithium in monotherapy. We used nationwide registers to identify all patients with a diagnosis of bipolar disorder in psychiatric hospital settings...... who were prescribed lithium from 1995 to 2006 in Denmark (N=3762). Excellent lithium responders were defined as patients who after a stabilization lithium start-up period of 6 months, continued lithium in monotherapy without getting hospitalized. The rate of excellent response to lithium...... with somatic comorbidity had increased rates of non-response to lithium compared with patients without somatic comorbidity (HR=1.23, 95% CI: 1.00-1.52).It is concluded that the prevalence of excellent response to lithium monotherapy is low and such patients are characterized by few earlier psychiatric...

    Full Text Available The neutral extractant, Cyanes-923 has been used for the extraction and separation of gallium(III, indium(III and thallium(III from acidic solution. These metal ions were found to be quantitatively extracted with Cyanex-923 in toluene in the pH range 4.5–5.5, 5.0–6.5 and 1.5–3.0, respectively, and from the organic phase they can be stripped with 2.0 mol dm-3 HNO3, 3.0 mol dm-3 HNO3 and 3.0 mol dm-3 HCl, respectively. The effect of pH equilibration period, diluents, diverse ions and stripping agents on the extraction of Ga(III, In(III and Tl(III has been studied. The stroichiometry of the extracted species of these metal ions was determined on the basis of the slope analysis method. The reaction proceed by solvation and the probable extracted species found were [MCl3. 3Cyanex-923] [where M = Ga(III or In(III ] and [HTlCl4. 3Cyanex-923]. Based on these results a sequential procedure for the separation of Ga(III, In(III and Tl(III from each other was developed.

    Although enuresis is relatively common in early childhood, research exploring its antecedents and implications is surprisingly limited, perhaps because the condition typically remits in middle childhood. We examined the prevalence, predictors, prognostic factors, and outcomes of primary enuresis in a large (N = 559) multi-method, multi-informant prospective study with a community-based sample of children followed from age 3 years to age 9 years. We found that 12.7% of our sample met criteria for lifetime enuresis, suggesting that it is a commonly occurring childhood disorder. Males were more than twice as likely as females to have a lifetime diagnosis. Significant age 3 predictors of developing primary enuresis by age 9 included child anxiety and low positive affectivity, maternal history of anxiety, and low authoritative parenting. In addition, poorer global functioning and more depressive and anxiety symptoms at age 3 years predicted a greater likelihood of persistence through age 9. By age 9 years, 77% of children who had received a diagnosis of primary enuresis were in remission and continent. However, children who had remitted exhibited a higher rate of attention-deficit/hyperactivity disorder (ADHD) and greater ADHD and depressive symptoms at age 9 compared to children with no lifetime history of enuresis. Results of the present study underscore the clinical significance of primary enuresis and demonstrate that it shows both strong antecedent and prospective associations with psychopathology. The findings also highlight the possible role of parenting in the development of enuresis. Copyright © 2016 American Academy of Child and Adolescent Psychiatry. Published by Elsevier Inc.

    The changes in parathyroid hormone secretion after successful renal transplantation remain to be clearly elucidated. Our study was aimed at identifying the predictors of hyperparathyroidism in renal transplant recipients. A retrospective single center study involving 37 renal transplant recipients, with a follow-up of at least one year, was performed. All transplants were performed using kidneys from living related donors. The average age of study patients was 30+-10 years, with a male-female ratio of 1.31. The mean duration on hemodialysis (HD) prior to transplantation was 25+-18 months. All the grafts but one were functional after a mean follow-up of 41+-21 months. We noted a rapid reduction of the mean parathyroid hormone (iPTH) level from 383+-265 pg/ml before transplantation to 125+-67 pg/ml at one year and 108+-66 pg/ml at two years after transplantation (p=0.01). Bivariate analysis revealed that the level of iPTH obtained during follow-up correlated with the duration on HD (p=0.03), the serum creatinine at 24-months (p=0.013), and to the level of iPTH in the first year post transplantation (P=<0.001). Other clinical or laboratory parameters were not predictive of hyperparathyroidism after kidney transplantation. Liner regression showed that only the serum creatinine at 24-months independently correlated with the level of iPTH at last follow-up (p=0.02). Our study suggests that short duration on HD and a functional graft are the main predictors of correction of hyperparathyroidism after renal transplantation. (author)

    A Gd(III)-nanodiamond conjugate [Gd(III)-ND] was prepared and characterized, enabling detection of nanodiamonds by MR imaging. The Gd(III)-ND particles significantly reduced the T1 of water protons with a per-Gd(III) relaxivity of 58.82 ± 1.18 mM−1s−1 at 1.5 Tesla (60 MHz). This represents a tenfold increase compared to the monomer Gd(III) complex (r1 = 5.42 ± 0.20 mM−1s−1) and is among the highest per-Gd(III) relaxivities reported. PMID:20038088

    Plasma disruptions pose a major threat to the operation of tokamaks which confine a large amount of stored energy. In order to effectively mitigate this damage it is necessary to predict an oncoming disruption with sufficient warning time to take mitigative action. Machine learning approaches to this problem have shown promise but require further developments to address (1) the need for machine-portable predictors and (2) the availability of multi-dimensional signal inputs. Here we demonstrate progress in these two areas by applying the Disruption Predictor Feature Developer to data from JET and NSTX, and discuss topics of focus for ongoing work in support of ITER. The author is also supported under the Fulbright U.S. Student Program as a graduate student in the department of Nuclear, Plasma and Radiological Engineering at the University of Illinois at Urbana-Champaign.

    1980-03-01

    In order to fully exploit Doublet III capabilities and to study new plasma physics regimes, a Neutral Beam Injector System has been constructed. Initially, a two beamline system will supply 7 MW of heat to the plasma. The system is currently being expanded to inject approx. 20 MW of power (6 beamlines). Each beamline is equipped with two Lawrence Berkeley Laboratory type rectangular ion sources with 10 cm x 40 cm extraction grids. These sources will accelerate hydrogen ions to 80 keV, with extracted beam currents in excess of 80 A per source expected. The first completed source is currently being tested and conditioned on the High Voltage Test Stand at Lawrence Livermore Laboratory. This paper pictorially reviews the as-built Doublet III neutral beamline with emphasis on component relation and configuration relative to spatial and source imposed design constraints

    The success of early orthopedic treatment in patients with Class III anomalies depends on facial skeletal development and type of treatment. This case report describes the treatment of a 12.6-year-old girl who had a severe Class III malocclusion with a 6-mm anterior crossbite, a deep overbite, a narrow maxilla, and unerupted maxillary canines. The treatment plan included rapid palatal expansion to expand the maxilla, reverse headgear to correct the maxillary retrognathia, a removable anterior inclined bite plane to correct the anterior crossbite and the deep overbite, and fixed edgewise appliances to align the teeth. One canine was brought into alignment, but the other was placed in occlusion in its transposed position. Ideal overjet and overbite relationships were established, and the final esthetic result was pleasing.

  8. Contemporary solutions for managing Class III malocclusion

    2015-01-01

    Full Text Available Although patients with Class III malocclusions constitute a small percentage of the average orthodontic practice, providing them with optimal treatment is a daunting task. The treatment approach is dependent upon the growth status of the individual and the severity of the skeletal dysplasia. For growing individuals, facemask therapy to protract the maxilla is ineffective because of its dependence on dental anchorage to bring forth skeletal correction. Orthodontic camouflage in nongrowing mild skeletal Class III individuals is met with limited success because of the anatomical boundaries and the conventional biomechanics. Orthognathic surgery to correct the maxillomandibular relations is time-consuming, and the facial esthetics is compromised during the orthodontic decompensation period. Contemporary solutions to overcome these limitations are now viable with the use of temporary anchorage devices and by performing surgery prior to orthodontic decompensation. The rationale for employing these contemporary approaches will be discussed in this study with illustrative cases.

    Full Text Available It was found that the growth curve of the rape embryo axis is of triple sigmoid type. Embryo growth occurs in 3 phases corresponding to 3 different periods of development. Phase I includes growth of the apical cell up to it's division into two layers of octants. Phase II comprises the increase of the spherical proembryo to the change of its symmetry from radial to bilateral. Phase III includes, growth of the embryo from the heart stage up to the end of embryogenesis. In each phase the relative growth rate increases drastically and then diminishes. The differences in growth intensity during the same phase are several-fold. The growth intensity maximum of the embryo axis occurs in phase II. The phasic growth intensity maxima occur: in phase I during apical cell elongation, :before its division, and in phases II and III in the periods of cell division ;growth in globular and torpedo-shaped -shaped embryos.

Multicenter prospective registry of patients with rheumatic inflammatory diseases being treated with biological drugs or synthetic drugs with an identifiable target in rheumatology departments in Spain. The main objective of BIOBADASER Phase III is the registry and analysis of adverse events; moreover, a secondary objective was added consisting of assessing the effectiveness by means of the registry of activity indexes. Patients in the registry are evaluated at least once every year and whenever they experience an adverse event or a change in treatment. The collection of data for phase iii began on 17 December 2015. During the first year, 35 centers participated. The number of patients included in this new phase in December 2016 was 2,664. The mean age was 53.7 years and the median duration of treatment was 8.1 years. In all, 40.4% of the patients were diagnosed with rheumatoid arthritis. The most frequent adverse events were infections and infestations. BIOBADASER Phase III has been launched to adapt to a changing pharmacological environment, with the introduction of biosimilars and small molecules in the treatment of rheumatic diseases. This new stage is adapted to the changes in the reporting of adverse events and now includes information related to activity scores.

    Separation of trivalent actinides (An(III)) and lanthanides (Ln(III)) is one of the most important steps in spent nuclear fuel reprocessing. However, it is very difficult and challenging to separate them due to their similar chemical properties. Recently the pyridylpyrazole ligand (PypzH) has been identified to show good separation ability toward Am(III) over Eu(III). In this work, to explore the Am(III)/Eu(III) separation mechanism of PypzH at the molecular level, the geometrical structures, bonding nature, and thermodynamic behaviors of the Am(III) and Eu(III) complexes with PypzH ligands modified by alkyl chains (Cn-PypzH, n = 2, 4, 8) have been systematically investigated using scalar relativistic density functional theory (DFT). According to the NBO (natural bonding orbital) and QTAIM (quantum theory of atoms in molecules) analyses, the M-N bonds exhibit a certain degree of covalent character, and more covalency appears in Am-N bonds compared to Eu-N bonds. Thermodynamic analyses suggest that the 1:1 extraction reaction, [M(NO 3 )(H 2 O) 6 ] 2+ + PypzH + 2NO 3 - → M(PypzH)(NO 3 ) 3 (H 2 O) + 5H 2 O, is the most suitable for Am(III)/Eu(III) separation. Furthermore, the extraction ability and the Am(III)/Eu(III) selectivity of the ligand PypzH is indeed enhanced by adding alkyl-substituted chains in agreement with experimental observations. Besides this, the nitrogen atom of pyrazole ring plays a more significant role in the extraction reactions related to Am(III)/Eu(III) separation compared to that of pyridine ring. This work could identify the mechanism of the Am(III)/Eu(III) selectivity of the ligand PypzH and provide valuable theoretical information for achieving an efficient Am(III)/Eu(III) separation process for spent nuclear fuel reprocessing.

    Angle, Tweed, and Moyers classified Class III malocclusions into 3 types: pseudo, dentoalveolar, and skeletal. Clinicians have been trying to identify the best timing to intercept a Class III malocclusion that develops as early as the deciduous dentition. With microimplants as skeletal anchorage, orthopedic growth modification became more effective, and it also increased the scope of camouflage orthodontic treatment for patients who were not eligible for orthognathic surgery. However, orthodontic treatment combined with orthognathic surgery remains the only option for patients with a severe skeletal Class III malocclusion or a craniofacial anomaly. Distraction osteogenesis can now be performed intraorally at an earlier age. The surgery-first approach can minimize the length of time that the malocclusion needs to worsen before orthognathic surgery. Finally, the use of computed tomography scans for 3-dimensional diagnosis and treatment planning together with advances in imaging technology can improve the accuracy of surgical movements and the esthetic outcomes for these patients.

    The clinical significance of the systemic inflammatory response (SIR) in patients with rectal cancer undergoing neoadjuvant chemoradiotherapy (CRT), to the best of our knowledge, has not been thus far investigated. The neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and C-Reactive protein (CRP) levels for 84 patients with rectal cancer undergoing CRT were available as indicators of SIR status. The impact of SIR status on the prognosis of these patients was assessed. Elevated NLR, CRP, carcinoembryonic antigen (CEA) and pathological TNM stage III [ypN(+)] were identified as significant prognostic factors for poor overall survival (OS), with CRP and ypN(+) being validated as independent predictors of OS. Elevated CRP and CEA levels were significant predictive factors for poor disease-free survival (DFS), and an elevated CRP level was identified as the only independent predictive factor for DFS. In addition, an elevated CRP level predicted for poorer OS and DFS in patients with pathological TNM stage I-II [ypN(-)]. CRP is a promising predictor of recurrence and prognosis in patients with rectal cancer treated by CRT.

    This study was designed to describe and evaluate the influence of a change in a Medicare reimbursement on the effectiveness of home health nursing care for stage III or greater decubitus ulcer patients. This health policy originated from the Balanced Budget Act (BBA) of 1997 and took its full effect with initiation of the Prospective Payment System (PPS) on October 1, 2000. A quantitative quasi-experimental design used OASIS data from the state of Virginia to evaluate 555 stage III or greater decubitus ulcer patients, age 65 or older. Comparisons were investigated between pre-PPS, 2000, and post-PPS, 2001, outcomes related to reported ulcer healing, lengths of stay, and discharge disposition. Results demonstrated significant differences for the outcomes studied. In addition, sanitation, ulcer healing, and discharge disposition were linked as predictors for length of stay. Results demonstrated that PPS has affected nursing care effectiveness for stage III or greater decubitus ulcer home health patients.

    High-Mobility-Group Box 1 (HMGB1) has been established as an important mediator of myocardial inflammation and associated with progression of heart failure (HF). The aim of this study was to analyze the prognostic value of systemic HMGB1 levels in HF patients with ischemic and non-ischemic cardiomyopathy. We conducted an analysis (median follow-up time 2.5 years) of HMGB1 plasma concentration in 154 patients with systolic HF and correlated the results with disease severity and prognosis. HMGB1 in HF patients with severe symptoms (NYHA III/IV; 5.35 ng/ml; interquartile range (IQR) = 3.48-8.42 ng/ml) was significantly elevated compared with that in patients with mild symptoms (NYHA I/II; 3.37 ng/ml, IQR = 2.31-5.22 ng/ml, p < 0.0001) and with controls (3.25 ng/ml, IQR = 3.04-3.67 ng/ml, p < 0.0001). HMGB1 levels correlated with other markers of heart failure indicating an association of HMGB1 with disease severity in HF. In a univariate cox regression model for the combined endpoint of death and heart transplantation, HMGB1 proved to be a predictor at cut-off values based on HMGB1 terciles of either 3.4 or 6.1 ng/ml (p = 0.001 and p < 0.0001, respectively). In a multivariate cox regression model, which included NT-proBNP, creatinine, age, NYHA class, white blood cell count, anemia, and age, HMGB1 remained an independent predictor of the combined endpoint (hazard ratio (HR) = 2.48, 95% confidence interval (CI) = 1.06-5.83, p = 0.037 and HR = 2.48, 95% CI = 1.31-4.71, p = 0.005, respectively). Our findings demonstrate that HMGB1 plasma concentration is elevated in HF and correlates with disease severity and that is an independent predictor of the combined endpoint death and heart transplantation in HF patients.

  3. Associations among Race/Ethnicity, ApoC-III Genotypes, and Lipids in HIV-1-Infected Individuals on Antiretroviral Therapy.

    2006-01-01

    Full Text Available BACKGROUND: Protease inhibitors (PIs are associated with hypertriglyceridemia and atherogenic dyslipidemia. Identifying HIV-1-infected individuals who are at increased risk of PI-related dyslipidemia will facilitate therapeutic choices that maintain viral suppression while reducing risk of atherosclerotic diseases. Apolipoprotein C-III (apoC-III gene variants, which vary by race/ethnicity, have been associated with a lipid profile that resembles PI-induced dyslipidemia. However, the association of race/ethnicity, or candidate gene effects across race/ethnicity, with plasma lipid levels in HIV-1-infected individuals, has not been reported. METHODS AND FINDINGS: A cross-sectional analysis of race/ethnicity, apoC-III/apoA-I genotypes, and PI exposure on plasma lipids was performed in AIDS Clinical Trial Group studies (n = 626. Race/ethnicity was a highly significant predictor of plasma lipids in fully adjusted models. Furthermore, in stratified analyses, the effect of PI exposure appeared to differ across race/ethnicity. Black/non-Hispanic, compared with White/non-Hispanics and Hispanics, had lower plasma triglyceride (TG levels overall, but the greatest increase in TG levels when exposed to PIs. In Hispanics, current PI antiretroviral therapy (ART exposure was associated with a significantly smaller increase in TGs among patients with variant alleles at apoC-III-482, -455, and Intron 1, or at a composite apoC-III genotype, compared with patients with the wild-type genotypes. CONCLUSIONS: In the first pharmacogenetic study of its kind in HIV-1 disease, we found race/ethnic-specific differences in plasma lipid levels on ART, as well as differences in the influence of the apoC-III gene on the development of PI-related hypertriglyceridemia. Given the multi-ethnic distribution of HIV-1 infection, our findings underscore the need for future studies of metabolic and cardiovascular complications of ART that specifically account for racial

    2001-01-01

    The luminescence lifetimes of An(III) and Ln(III) ions [An=Am and Cm; Ln=Nd, Sm, Eu, Tb and Dy] were measured in dimethyl sulfoxide(DMSO), N,N-dimethylformamide(DMF), methanol(MeOH), water and their perdeuterated solvents. Nonradiative decay rates of the ions were in the order of H 2 O > MeOH > DMF > DMSO, indicating that O-H vibration is more effective quencher than C-H, C=O, and S=O vibrations in the solvent molecules. Maximal lifetime ratios τ D /τ H were observed for Eu(III) in H 2 O, for Sm(III) in MeOH and DMF, and for Sm(III) and Dy(III) in DMSO. The solvent composition in the first coordination sphere of Cm(III) and Ln(III) in binary mixed solvents was also studied by measuring the luminescence lifetime. Cm(III) and Ln(III) were preferentially solvated by DMSO in DMSO-H 2 O, by DMF in DMF-H 2 O, and by H 2 O in MeOH-H 2 O over the whole range of the solvent composition. The order of the preferential solvation, i.e., DMSO > DMF > H 2 O > MeOH, correlates with the relative basicity of these solvents. The Gibbs free energy of transfer of ions from water to nonaqueous solvents was further estimated from the degree of the preferential solvation. (orig.)

    Older maternal age has become more common in Japan. Studies suggest that older maternal age and primiparity are associated with post-partum depression. The present study aimed to identify predictors of post-partum depression in older Japanese primiparas at 1 month post-partum. Participants were 479 primiparas aged 35 years and over, drawn from a prospective cohort study. Data were collected using self-report questionnaires. Depression was measured with the Japanese version of the Edinburgh Postnatal Depression Scale. Stepwise logistic regression analysis was conducted on binary outcome variables of depression at 1 month post-partum, along with a stratified analysis based on the risk status of depression. Five predictors were identified: (i) the depression score during hospital stay; (ii) financial burden; (iii) dissatisfaction with appraisal support; (iv) physical burden in daily life; and (v) concerns about infant caretaking. Stratified analysis identified dissatisfaction with instrumental support in the low-risk group, and the Child-care Value Scale score as unique predictors in the high-risk group. These results highlight the importance of early assessment of depressive symptoms and the provision of continuous care. © 2015 Japan Academy of Nursing Science.

    To evaluate the potential health risks caused by the ingestion of lanthanides (Ln) and actinides (An), investigations into the chemical behavior of these metals in the human gastrointestinal tract are necessary. Mucin is an important part of the protective mucosa layer in the digestive system. We have recently reported that mucin interacts strongly with Eu(III) and Cm(III), representatives of Ln(III) and An(III), respectively, under in vivo conditions. In order to investigate the complexation behavior of this protein with Ln(III)/An(III), TRLFS measurements were performed on Eu(III)/Cm(III)-mucin solutions with different protein concentrations and at different pH. The results indicate the formation of at least two independent mucin species. At higher pH, the formation of hydroxide species was also observed.

  17. Mechanisms for Fe(III) oxide reduction in sedimentary environments

    Nevin, Kelly P.; Lovely, Derek R.

    2002-01-01

    Although it was previously considered that Fe(III)-reducing microorganisms must come into direct contact with Fe(III) oxides in order to reduce them, recent studies have suggested that electron-shuttling compounds and/or Fe(III) chelators, either naturally present or produced by the Fe(III)-reducing microorganisms themselves, may alleviate the need for the Fe(III) reducers to establish direct contact with Fe(III) oxides. Studies with Shewanella alga strain BrY and Fe(III) oxides sequestered within microporous beads demonstrated for the first time that this organism releases a compound(s) that permits electron transfer to Fe(III) oxides which the organism cannot directly contact. Furthermore, as much as 450 w M dissolved Fe(III) was detected in cultures of S. alga growing in Fe(III) oxide medium, suggesting that this organism releases compounds that can solublize Fe(III) from Fe(III) oxide. These results contrast with previous studies, which demonstrated that Geobacter metallireducens does not produce electron-shuttles or Fe(III) chelators. Some freshwater aquatic sediments and groundwaters contained compounds, which could act as electron shuttles by accepting electrons from G. metallireducens and then transferring the electrons to Fe(III). However, other samples lacked significant electron-shuttling capacity. Spectroscopic studies indicated that the electron-shuttling capacity of the waters was not only associated with the presence of humic substances, but water extracts of walnut, oak, and maple leaves contained electron-shuttling compounds did not appear to be humic substances. Porewater from a freshwater aquatic sediment and groundwater from a petroleum-contaminated aquifer contained dissolved Fe(III) (4-16 w M), suggesting that soluble Fe(III) may be available as an electron acceptor in some sedimentary environments. These results demonstrate that in order to accurately model the mechanisms for Fe(III) reduction in sedimentary environments it will be necessary

    OBJECTIVE Despite persisting questions regarding its appropriateness, 30-day readmission is an increasingly common quality metric used to influence hospital compensation in the United States. However, there is currently insufficient evidence to identify which patients are at highest risk for readmission after aneurysmal subarachnoid hemorrhage (SAH). The objective of this study was to identify predictors of 30-day readmission after SAH, to focus preventative efforts, and to provide guidance to funding agencies seeking to risk-adjust comparisons among hospitals. METHODS The authors performed a case-control study of 30-day readmission among aneurysmal SAH patients treated at a single center between 2003 and 2013. To control for geographic distance from the hospital and year of treatment, the authors randomly matched each case (30-day readmission) with approximately 2 SAH controls (no readmission) based on home ZIP code and treatment year. They evaluated variables related to patient demographics, socioeconomic characteristics, comorbidities, presentation severity (e.g., Hunt and Hess grade), and clinical course (e.g., need for gastrostomy or tracheostomy, length of stay). Conditional logistic regression was used to identify significant predictors, accounting for the matched design of the study. RESULTS Among 82 SAH patients with unplanned 30-day readmission, the authors matched 78 patients with 153 nonreadmitted controls. Age, demographics, and socioeconomic factors were not associated with readmission. In univariate analysis, multiple variables were significantly associated with readmission, including Hunt and Hess grade (OR 3.0 for Grade IV/V vs I/II), need for gastrostomy placement (OR 2.0), length of hospital stay (OR 1.03 per day), discharge disposition (OR 3.2 for skilled nursing vs other disposition), and Charlson Comorbidity Index (OR 2.3 for score ≥ 2 vs 0). However, the only significant predictor in the multivariate analysis was discharge to a skilled

    Full Text Available Background Preterm birth represents the most frequent complication of pregnancy all over the world. Much research is addressed to psychomotor development of preterm infants during the initial years of their life. Many authors emphasize the role of birth weight, gestational age, and gender in determining the child’s psychomotor development. This study adds to this knowledge as we analyzed the synergistic effect of biomedical predictors such as gestational age, birth weight, Apgar score, time in incubator, type of pregnancy defined based on its outcome, neonatal status immediately after delivery, infant’s gender, and possessing twin sibling. Combined effects of these factors represent an important niche in the studies of the developmental psychology of preterm infants. Participants and procedure The study included 49 preterm infants born in 2008-2009 at the Department of Obstetrics of the Medical University of Gdańsk. The psychomotor development of preterm infants was evaluated according to the Bayley Scales of Infant and Toddler Development®, Third Edition (BSID-III at a mean, non-corrected age of 33.80 months (SD = 5.16. For the purpose of the study we developed a basic model in the form of a pathway diagram, describing the cumulative influence of eight biomedical predictors on the development of the infants during early childhood. Results Our study revealed a synergistic influence of biomedical predictors on the development of preterm infants with regards to cognitive functioning (28% of variance, language skills (10% of variance, motor skills (18% of variance, fine motor skills (16% of variance, and gross motor skills (20% of variance. Moreover, we observed an independent effect of birth weight, child’s gender, and final Apgar score on the psychomotor development of preterm infants. Higher birth weight was associated with higher level of cognitive function and fine motor skills. Male gender of a child was reflected by a higher level of

    The nonhomogeneous hidden Markov model (NHMM) statistical downscaling model, 38 catchments in southeast Australia and 19 general circulation models (GCMs) were used in this study to demonstrate statistical downscaling uncertainties caused by equifinality to and transferability. That is to say, there could be multiple sets of predictors that give similar daily rainfall simulation results for both calibration and validation periods, but project different amounts (or even directions of change) of rainfall changing in the future. Results indicated that two sets of predictors (Set 1 with predictors of sea level pressure north-south gradient, u-wind at 700 hPa, v-wind at 700 hPa, and specific humidity at 700 hPa and Set 2 with predictors of sea level pressure north-south gradient, u-wind at 700 hPa, v-wind at 700 hPa, and dewpoint temperature depression at 850 hPa) as inputs to the NHMM produced satisfactory results of seasonal rainfall in comparison with observations. For example, during the model calibration period, the relative errors across the 38 catchments ranged from 0.48 to 1.76% with a mean value of 1.09% for the predictor Set 1, and from 0.22 to 2.24% with a mean value of 1.16% for the predictor Set 2. However, the changes of future rainfall from NHMM projections based on 19 GCMs produced projections with a different sign for these two different sets of predictors: Set 1 predictors project an increase of future rainfall with magnitudes depending on future time periods and emission scenarios, but Set 2 predictors project a decline of future rainfall. Such divergent projections may present a significant challenge for applications of statistical downscaling as well as climate change impact studies, and could potentially imply caveats in many existing studies in the literature.

Hierarchical logistic regression analyses showed that The Theory of Planned Behaviour (TPB) significantly predicted WTP. Of all the predictors, Subjective norms significantly predicted WTP (OR = 1.19, 95% C.I. = 1.06-1.34). A stepwise logistic regression analysis revealed that Subjective Norms (OR = 1.19, 95% C.I. = 1.07-1.34) and Attitude towards participation in an HIV vaccine trial (OR = 1.32, 95% C.I. = 1.00-1.74) were significant predictors of WTP. The addition of Knowledge of HIV vaccines and HIV vaccine trials, Perceived self-risk of HIV infection, Health-promoting behaviours and Attitudes towards HIV/AIDS yielded non-significant results. These findings provide support for the Theory of Reasoned Action (TRA) and suggest that psychosocial factors may play an important role in WTP in Phase III HIV vaccine trials among adolescents.

    Reactions of 9,10-phenanthrenequinone (PQ) in toluene with [M(II)(PPh3)3X2] at 298 K afford green complexes, trans-[M(PQ)(PPh3)2X2] (M = Ru, X = Cl, 1; M = Os, X = Br, 2) in moderate yields. Reaction of anhydrous RhCl3 with PQ and PPh3 in boiling ethanol affords the dark brown paramagnetic complex, cis-[Rh(PQ)(PPh3)2Cl2] (3) in good yields. Diffusion of iodine solution in n-hexane to the trans-[Os(PQ) (PPh3)2(CO)(Br)] solution in CH2Cl2 generates the crystals of trans-[Os(PQ)(PPh3)2(CO)(Br)](+)I3(-), (4(+))I3(-)), in lower yields. Single crystal X-ray structure determinations of 1·2toluene, 2·CH2Cl2 and 4(+)I3(-), UV-vis/NIR absorption spectra, EPR spectra of 3, electrochemical activities and DFT calculations on 1, 2, trans-[Ru(PQ)(PMe3)2Cl2] (1Me), trans-[Os(PQ)(PMe3)2Br2] (2Me), cis-[Rh(PQ)(PMe3)2Cl2] (3Me) and their oxidized and reduced analogues including trans-[Os(PQ)(PMe3)2(CO)(Br)](+) (4Me(+)) substantiated that 1-3 are the 9,10-phenanthrenesemiquinone radical (PQ(˙-)) complexes of ruthenium(III), osmium(III) and rhodium(III) and are defined as trans/cis-[M(III)(PQ(˙-))(PPh3)2X2] with a minor contribution of the resonance form trans/cis-[M(II)(PQ)(PPh3)2X2]. Two comparatively longer C-O (1.286(4) Å) and the shorter C-C lengths (1.415(7) Å) of the OO-chelate of 1·2toluene and 2·CH2Cl2 and the isotropic fluid solution EPR signal at g = 1.999 of 3 are consistent with the existence of the reduced PQ(˙-) ligand in 1-3 complexes. Anisotropic EPR spectra of the frozen glasses (g11 = g22 = 2.0046 and g33 = 1.9874) and solids (g11 = g22 = 2.005 and g33 = 1.987) instigate the contribution of the resonance form, cis-[Rh(II)(PQ)(PPh3)2Cl2] in 3. DFT calculations established that the closed shell singlet (CSS) solutions of 1Me and 2Me are unstable due to open shell singlet (OSS) perturbation. However, the broken symmetry (BS) (1,1) Ms = 0 solutions of 1Me and 2Me are respectively 22.6 and 24.2 kJ mole(-1) lower in energy and reproduced the experimental bond

    Copper(III) and total copper in superconducting Y-Ba-Cu oxide and related compounds can be determinated by two successive iodimetric titrations after the sample has been dissolved under Ar in HCl/KI medium. First, the iodine equivalent to copper(III) is titrated with Na 2 S 2 O 3 solution at pH 4.8, copper(II) being masked with EDTA. The total copper is then determined in the same solution by demasking with acid and iodide, followed by iodimetric titration. The method is both accurate and reproducible. The relative standard deviations for 1.074% copper(III) and 23.37% total copper are 0.8% and 0.3%, respectively. (orig.)

    The binuclear [FeIII(bpca)(mu-bpca)Dy(NO3)4], having Single Molecule Magnet (SMM) properties, belonging to a series of isostructural FeIIILnIII complexes (Ln = Eu, Gd, Tb, Dy, Ho) and closely related FeIILnIII chain structures, was characterized in concise experimental and theoretical respects. The low temperature magnetization data showed hysteresis and tunneling. The anomalous temperature dependence of Mössbauer spectra is related to the onset of magnetic order, consistent with the magnetization relaxation time scale resulting from AC susceptibility measurements. The advanced ab initio calculations (CASSCF and spin-orbit) revealed the interplay of ligand field, spin-orbit, and exchange effects and probed the effective Ising nature of the lowest states, involved in the SMM and tunneling effects.

    A derivative of diethylenetriamine-N,N,N',N'',N''-pentaacetic acid (DTPA), carrying two catechol functional groups has been synthesised by the reaction between DTPA-bis(anhydride) and 3-hydroxytyramine (dopamine). The ligand DTPA-bis(3-hydroxytyramide), [DTPA(HTA) 2 ], is able to form stable heterobimetallic complexes with gadolinium(III) and iron(III) ions. The gadolinium(III) occupies the internal coordination cage of DTPA formed by three nitrogens, two carboxylate and two amide oxygens, while the [Fe(NTA)(H 2 O) 2 ] (nitrilotriacetic acid, NTA) binds to catechol units by the substitution of two water ligands. The formation of polymeric species was avoided by using the tripodal NTA ligand. The heterobimetallic complex was characterised by means of visible absorption spectroscopy, electron spray ionisation-mass spectrometry (ESI-MS), and nuclear magnetic resonance (NMR) spectroscopy

    Research on the effects of entrepreneurial stressors is limited, especially regarding its relation to the burnout that frequently occurs in the process of starting and growing a venture. The effect of the role of entrepreneurial stressors (workload, competitive comparison, demands-of-knowledge, managing responsibility, and resource requirements) on burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment) was examined in a Chinese sample of entrepreneurs. Entrepreneurial stressors emerged as a significant predictor of burnout in the process of entrepreneurship in a sample of 289 entrepreneurs (63.8% men; M age = 26.2 yr.; 39.6% of their parents have been self-employed). The findings clarify the functional relationship between entrepreneurial stressors and burnout. Entrepreneurial stressors played multiple roles. Managing responsibility was an active contributor to the sense of achievement and to emotional exhaustion. Workload was an active contributor to emotional exhaustion. Demands-of-knowledge negatively affected three of the dimensions of burnout. Theoretical and practical implications for management of the effect of these relationships are discussed.

    This prospective study was designed to analyze the dependence of different factors on the recurrence rate of chronic subdural hematoma (cSDH) after surgical treatment. Seventy-three consecutive patients, who were surgically treated at our department due to cSDH between 2009 and 2012, were included. The following parameters were analyzed: patient age and gender, occurrence of trauma, time between trauma and admission, neurological symptoms, presence of minor diseases, intake of anticoagulation medication. We classified the results of diagnostic imaging and determined the space-consuming effect via the cerebral midline shift. In addition, we scrutinized intraoperative findings and the dependence of the position of subdural drainage on the recurrence rate of cSDH. In our patient group, cSDH recurrence was significantly associated with aphasia (p=0.008). Moreover an increased cSDH recurrence rate was observed in the patient group that had a separated manifestation of the cSDH in the preoperative diagnostic imaging (p=0.048) and received no drainage implant (p=0.016). Homogeneous isodense cSDH was associated with no apparent recurrence (p=0.037). Within the scope of this study, we detected aphasia and separated cSDH as predictors of cSDH recurrence. Homogeneous isodense cSDH seems to be a good prognostic sign regarding the risk of recurrence development. Furthermore, our data clearly emphasize the importance of surgically applied drainage implants to prevent a recurrence of cSDH.

    The aim of this study was to establish predictors for successfully planned extubation, which can be followed by medical personnel. The patients who were admitted to the adult intensive care unit of a tertiary hospital and met the following criteria between January 2005 and December 2014 were collected retrospectively: intubation > 48 hours; and candidate for extubation. The patient characteristics, including disease severity, rapid shallow breath index (RSBI), maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), cuff leak test (CLT) before extubation, and outcome, were recorded. The CLT was classified as 2+ with audible flow without a stethoscope, 1+ with audible flow using a stethoscope, and negative (N) with no audible flow, even with a stethoscope. Failure to extubate was defined as reintubation within 48 hours. In total, 6583 patients were enrolled and 403 patients (6.1%) had extubation failures. Male patients dominated the patient cohort (4261 [64.7%]). The mean age was 64.5±16.3 years. The overall in-hospital mortality rate was 11.3%. The extubation failure rate for females was greater than males (7.7% vs 5.3%, P respiratory capacity, was developed to better predict extubation success.

    Approximately 80% of patients with ulcerative colitis (UC) have intermittently active disease and up to 20% will require a colectomy, but little data available on predictors of poor disease course. The aim of this study was to identify clinical and genetic markers that can predict prognosis. Medical records of patients with UC with ≥5 years of follow-up and available DNA and serum were retrospectively assessed. Immunochip was used to genotype loci associated with immune mediated inflammatory disorders (IMIDs), inflammatory bowel diseases, and other single nucleotide polypmorphisms previously associated with disease severity. Serum levels of pANCA, ASCA, CBir1, and OmpC were also evaluated. Requirement for colectomy, medication, and hospitalization were used to group patients into 3 prognostic groups. Six hundred one patients with UC were classified as mild (n = 78), moderate (n = 273), or severe disease (n = 250). Proximal disease location frequencies at diagnosis were 13%, 21%, and 30% for mild, moderate, and severe UC, respectively (P = 0.001). Disease severity was associated with greater proximal extension rates on follow-up (P 40 and proximal disease location were associated with severe UC (odds ratios = 1.94 and 2.12, respectively). None of the single nucleotide polypmorphisms or serum markers tested was associated with severe UC, proximal disease extension or colectomy. Older age and proximal disease location at diagnosis, but not genetic and serum markers, were associated with a more severe course. Further work is required to identify biomarkers that will predict outcomes in UC.

    This project examines how access issues, ethnicity, and geographic region affect vaccination of children by two years of age in Bolivia. Bolivia's rich variation in culture and geography results in unequal healthcare utilization even for basic interventions such as childhood vaccination. This study utilizes secondary data from the 2008 Demographic and Health Survey for Bolivia to examine predictors of vaccination completion in children by two years of age. Using logistic regression methods, we control for health system variables (difficulty getting to a health center and type of health center as well as demographic and socio-economic covariates). The results indicated that children whose parents reported distance as a problem in obtaining health care were less likely to have completed all vaccinations. Ethnicity was not independently statistically significant, however, in a sub-analysis, people from the Quechua ethnic group were more likely to report 'distance as a problem in obtaining healthcare.' Surprisingly, living in a rural environment has a protective effect on completed vaccinations. However, geographic region did predict significant differences in the probability that children would be fully vaccinated; children in the region with the lowest vaccination completion coverage were 80% less likely to have completed vaccination compared to children in the best performing region, which may indicate unequal access and utilization of health services nationally. Further study of regional differences, urbanicity, and distance as a healthcare access problem will help refine implications for the Bolivian health system.

    University students often face different stressful situations and preoccupations: the first contact with the university, the freedom of schedule organization, the selection of their master's degree, very selective fields, etc. The purpose of this study is to evaluate a model of vulnerability to stress in French college students. Stress factors were evaluated by a battery of six scales that was accessible online during 3 months. A total of 483 students, aged between 18 and 24 years (Mean = 20.23, standard deviation = 1.99), was included in the study. The results showed that 72.9, 86.3, and 79.3% of them were suffering from psychological distress, anxiety and depressive symptoms, respectively. More than half the sample was also suffering from low self-esteem (57.6%), little optimism (56.7%), and a low sense of self-efficacy (62.7%). Regression analyses revealed that life satisfaction, self-esteem, optimism, self-efficacy and psychological distress were the most important predictors of stress. These findings allow us to better understand stress-vulnerability factors in students and drive us to substantially consider them in prevention programs.

    CONTEXT AND OBJECTIVES Falls are a serious public health problem and are one of the biggest reasons for hospitalization, morbidity and mortality among elderly people. Moreover, few studies on predictors of falls have been conducted in low and middle income countries. The aim here was to identify elderly outpatient profiles according to sociodemographic, clinical, physical and functional variables and correlate them with occurrences of falls among these subjects. DESIGN AND SETTING Cross-sectional descriptive study forming part of the project "Quality of Life of Frail Elderly People", carried out in Campinas, Brazil. METHODS The subjects were 145 elderly individuals (76.3 ± 7.8 years old), of whom 65% were women, who were living in the city of Campinas or nearby and were attended at the geriatric outpatient clinic of a University Hospital. Sociodemographic, clinical, physical and functional data, as well as fall occurrence data, were gathered. Cluster analyses and comparisons between groups were carried out. RESULTS Cluster analysis identified two distinct groups related to the study variables, and the determinants for this distinction were: gender, marital status, physical performance, handgrip strength and functional independence. These groups were compared according to occurrences of falls over the last year, and significant differences between them were found. CONCLUSIONS The results showed that greater occurrences of falls were associated with a profile of elderly people comprising female gender, single status, lower muscle strength and physical performance regarding balance and gait, and lower independence in motor tasks for activities of daily living.

    Full Text Available This study aimed to identify actual and perceived barriers to postpartum care among a probability sample of women who gave birth in Los Angeles County, California in 2007. Survey data from the 2007 Los Angeles Mommy and Baby (LAMB study (N = 4,075 were used to identify predictors and barriers to postpartum care use. The LAMB study was a cross-sectional, population-based study that examined maternal and child health outcomes during the preconception, prenatal, and postpartum periods. Multivariable analyses identified low income, being separated/divorced and never married, trying hard to get pregnant or trying to prevent pregnancy, Medi-Cal insurance holders, and lack of prenatal care to be risk factors of postpartum care nonuse, while Hispanic ethnicity was protective. The most commonly reported barriers to postpartum care use were feeling fine, being too busy with the baby, having other things going on, and a lack of need. Findings from this study can inform the development of interventions targeting subgroups at risk for not obtaining postpartum care. Community education and improved access to care can further increase the acceptability of postpartum visits and contribute to improvements in women’s health. Postpartum care can serve as a gateway to engage underserved populations in the continuum of women’s health care.

    Full Text Available The aim of the present study is to explore a variety of cognitive and social variables which are most relevant to children’s linguistic success in an educational setting. The study examines kindergarten English language outcomes in classrooms containing monolingual English speaking children and bilingual children who speak English and one other language. Data from the National Center for Early Development and Learning Multistate Study of Pre-Kindergarten (2001-2003 regarding classroom and student characteristics were used for bilingual (N = 120 and monolingual (N = 534 children. Hierarchical regression analysis (Study 1 and path analysis (Study 2 were conducted to determine the cognitive and social variables present in preschool that are most predictive of English skills in kindergarten. The results of the studies demonstrate that social variables were important for both monolingual and bilingual children. Personality variables were more predictive for monolingual children, whereas teacher relationship variables were more important for bilingual children. Simple and routine adult interaction was predictive of English skills in both groups, which may indicate the importance of implicit learning over explicit instruction in early language acquisition. The present studies found different predictors of English language skills for monolingual and bilingual kindergarteners.

    2006-09-01

    To prospectively study the stability of anabolic androgenic steroid (AAS) use and predictors of AAS use, and to investigate whether AAS use alters the risk of later emotional and behavioral problems. Survey of a national sample of Norwegian high school students (age 15-19) in 1994 followed up in 1999 (N = 2924). Measures of frequent alcohol intoxication (50+ times per 12 months), cannabis use (12 months), hard drug use (12 months), being offered cannabis, eating problems, conduct problems, sexual debut before age 15, BMI, involvement in power sports, perceived physical appearance, and satisfaction with body parts were obtained. Life-time prevalence of AAS use were 1.9 and 0.8% in the follow-up period. Multivariate logistic regression revealed that future AAS use was predicted by young age, male gender, previous AAS use, involvement in power sports, and frequent alcohol intoxication. AAS use did not predict future emotional or behavioral problems other than reducing the risk of future frequent alcohol intoxication. Frequent alcohol intoxication and involvement in power sports appear to predict future AAS use. At the population level there was little stability in individual AAS use from adolescence to early adulthood. No detrimental effects of AAS use could be detected in this study, but low statistical power limits this conclusion.

    To understand key drivers of patient satisfaction in pediatric hematology/oncology. The "top-box" scores of patient satisfaction surveys from 4 pediatric hematology/oncology practices were collected from 2012 to 2014 at an integrated Children's Health Network. One item, "Likelihood of recommending practice," was used as the surrogate for overall patient satisfaction, and all other items were correlated to this item. A total of 1244 satisfaction surveys were included in this analysis. The most important predictors of overall patient satisfaction were cheerfulness of practice ( r = .69), wait time ( r = .60), and staff working together ( r = .60). The lowest scoring items were getting clinic on phone, information about delays, and wait time at clinic. Families bringing their children for outpatient care in a hematology/oncology practice want to experience a cheerful and collaborative medical team. Wait time at clinic may be a key driver in the overall experience for families with children with cancer. Future work should be directed at using this evidence to drive patient experience improvement processes in pediatric hematology/oncology.

    Despite numerous initiatives to increase solid organs for transplant, the gap between donors and recipients widens. There is little in the literature identifying socioeconomic predictors for donation. We evaluate the correlation between socioeconomic factors and familial authorization for donation. A retrospective analysis of adult potential donor referrals between 2007 and 2012 to our organ procurement organization (OPO) was performed. Potential donor information was obtained from the OPO database, death certificates, and the US Census Report. Data on demographics, education, residence, income, registry status, cause and manner of death, as well as OPO assessments and approach for donation were collected. End point was familial authorization for donation. A total of 1059 potential donors were included, with an overall authorization rate of 47%. The majority was not on the donor registry (73%). Younger donors (18-39 y: odds ratio [OR] = 4.9, P donation first mentioned by the local health care provider (OR = 1.8, P = 0.01) were also independently associated with higher authorization rates. Donor registration correlated most strongly with the highest authorization rates. These results indicate that public educational efforts in populations with unfavorable socioeconomic considerations may be beneficial in improving donor registration. Collaborations with local providers as well as OPO in-hospital assessments and approach techniques can help with improving authorization rates. Copyright © 2017 Elsevier Inc. All rights reserved.

    The objective of this study was to identify factors that predict restraint use and optimal restraint use among children aged 0 to 13 years. The data set is a national sample of police-reported crashes for years 2010-2014 in which type of child restraint is recorded. The data set was supplemented with demographic census data linked by driver ZIP code, as well as a score for the state child restraint law during the year of the crash relative to best practice recommendations for protecting child occupants. Analysis used linear regression techniques. The main predictor of unrestrained child occupants was the presence of an unrestrained driver. Among restrained children, children had 1.66 (95% confidence interval, 1.27, 2.17) times higher odds of using the recommended type of restraint system if the state law at the time of the crash included requirements based on best practice recommendations. Children are more likely to ride in the recommended type of child restraint when their state's child restraint law includes wording that follows best practice recommendations for child occupant protection. However, state child restraint law requirements do not influence when caregivers fail to use an occupant restraint for their child passengers.
