The role of demographic compensation theory in incidental take assessments for endangered species
McGowan, Conor P.; Ryan, Mark R.; Runge, Michael C.; Millspaugh, Joshua J.; Cochrane, Jean Fitts
2011-01-01
Many endangered species laws provide exceptions to legislated prohibitions through incidental take provisions as long as take is the result of unintended consequences of an otherwise legal activity. These allowances presumably invoke the theory of demographic compensation, commonly applied to harvested species, by allowing limited harm as long as the probability of the species' survival or recovery is not reduced appreciably. Demographic compensation requires some density-dependent limits on survival or reproduction in a species' annual cycle that can be alleviated through incidental take. Using a population model for piping plovers in the Great Plains, we found that when the population is in rapid decline or when there is no density dependence, the probability of quasi-extinction increased linearly with increasing take. However, when the population is near stability and subject to density-dependent survival, there was no relationship between quasi-extinction probability and take rates. We note however, that a brief examination of piping plover demography and annual cycles suggests little room for compensatory capacity. We argue that a population's capacity for demographic compensation of incidental take should be evaluated when considering incidental allowances because compensation is the only mechanism whereby a population can absorb the negative effects of take without incurring a reduction in the probability of survival in the wild. With many endangered species there is probably little known about density dependence and compensatory capacity. Under these circumstances, using multiple system models (with and without compensation) to predict the population's response to incidental take and implementing follow-up monitoring to assess species response may be valuable in increasing knowledge and improving future decision making.

Esplenectomía incidental: ¿Está justificada?
Directory of Open Access Journals (Sweden)
Eddy Sierra Enrique
1997-12-01
Full Text Available Se revisaron 77 historias clínicas de pacientes que presentaban lesiones incidentales del bazo ocurridas entre 1985 y 1994, durante operaciones intraabdominales y por examen laparoscópico. Las funciones inmunológicas del bazo y su papel contra las infecciones están bien definidas, por lo cual al ser suprimido este órgano a consecuencia de lesiones incidentales, favorecen las infecciones en dichos pacientes de por vida. De las 77 lesiones incidentales se realizaron 47(61 % esplenectomías incidentales y 30(39 % cirugías conservadoras. La úlcera duodenal y la hernia hiatal son las causas principales de esplenectomía incidental. Se presentaron 11 infecciones (23,4 % y 1 fallecido (2,1 % en la esplenectomía incidental contra 1 infección (3,3 % y ningún fallecido en la cirugía conservadora. Se llega a la conclusión de que la esplenectomía no está justificada dadas las desventajas que presenta77 medical histories of patients who presented incidental injuries of the spleen occurred between 1985 and 1994, during intraabdominal operations and by laparoscopic examination, were reviewed. The immunological functions of the spleen and its role against infections are well defined, so the removal of this organ due to incidental injuries favors the appearance of infections in these patients for the rest of their lives. Of the 77 incidental injuries 47 (61 % incidental splenectomies and 30 (39 % conservative surgeries were performed. Duodenal ulcer and hiatal hernia proved to be the main causes of incidental splenectomy. There were 11 infections (23.4 % and 1 death (2.1 % in the incidental splenectomy compared with 1 infection (3.3 % and no death in the conservative surgery. It is concluded that splenectomy is not justified because of its disadvantages

Preparation of two-dimensional (2D) heterostructures is important not only fundamentally, but also technologically for applications in electronics and optoelectronics. Herein, we report a facile colloidal method for the synthesis of WO{sub n}-WX{sub 2} (n=2.7, 2.9; X=S, Se) heterostructures by sulfurization or selenization of WO{sub n} nanomaterials. The WO{sub n}-WX{sub 2} heterostructures are composed of WO{sub 2.9} nanoparticles (NPs) or WO{sub 2.7} nanowires (NWs) grown together with single- or few-layer WX{sub 2} nanosheets (NSs). As a proof-of-concept application, the WO{sub n}-WX{sub 2} heterostructures are used as the anode interfacial buffer layer for green quantum dot light-emitting diodes (QLEDs). The QLED prepared with WO{sub 2.9} NP-WSe{sub 2} NS heterostructures achieves external quantum efficiency (EQE) of 8.53 %. To our knowledge, this is the highest efficiency in the reported green QLEDs using inorganic materials as the hole injection layer. (copyright 2017 Wiley-VCH Verlag GmbH and Co. KGaA, Weinheim)

Full Text Available Los lipomas intracraneales son lesiones infrecuentes y benignas que representan el 0,03 al 0,08% de todas las masas intracraneales. Estos se encuentran relacionados a un defecto de la línea media debido a un mal cierre del tubo neural; lo que conlleva a una mala diferenciación y una persistencia anormal de la meninge primitiva con posterior diferenciación al tejido adiposo. La mitad de los casos permanecen asintomáticos y son diagnosticados como un hallazgo incidental en los estudios imagenológicos. Sin embargo, otros casos se asocian a sintomatología neurológica como retraso psicomotor, cefalea, epilepsia y parálisis cerebral.

Previous studies have addressed the prevalence of incidental findings largely in healthy adult and pediatric populations. Our study aims to elucidate the prevalence of incidental findings in a pediatric neurology practice. We reviewed the charts of 1618 patients seen at a pediatric neurology practice at a tertiary care center from September 2003 to December 2005 for clinical data and incidental intracranial findings on brain magnetic resonance imaging reports. Incidental findings were divided into two categories: normal or abnormal variants. Clinical and demographic data were assessed for associations with incidental findings. From 1618 charts reviewed, only 666 patients (41% of all patients) had brain MRIs ordered. One-hundred and seventy-one (171) patients (25.7% of all patients; 95% CI: 22.6, 29.0) had incidental findings. Of these, 113 (17.0%; 95% CI: 14.1, 19.8) were classified as normal-variants and 58 (8.7%; 95% CI: 6.6, 10.9) were classified as abnormal. The nature of incidental findings was not related to age group, sex or clinical diagnosis (p=0.29, p=0.31 and p=0.69 respectively). Two patients (0.3%; 95% CI: approximately 0.0, 0.7) required neurosurgical referral. We report a high prevalence of and a low rate of referrals for incidental findings in comparison to previous studies. The present study may help guide management decisions and discussions with patients and families. Future studies should attempt to address issues of associations between primary or secondary diagnoses and intracranial incidental findings in a controlled, prospective fashion.

INCIDENTAL VOCABULARY LEARNING THROUGH READING
Directory of Open Access Journals (Sweden)
Holly Warzecha, M.A. TESOL
2017-04-01
Full Text Available The purpose of the following paper is to take a closer look at the benefits of incidental learning through reading, with a specific focus on vocabulary acquisition. The teaching of vocabulary has traditionally been an explicit process where the target vocabulary is taken out of context and taught separately. However, this kind of explicit teaching and learning may only take into account a form-meaning connection. Therefore, this paper explores research on incidental learning and specifically looks at what it takes to acquire new vocabulary incidentally through reading while considering the coverage rates of texts, how many words must be known already from the text, how many repetitions it takes to learn a word, types of texts that promote learning, and the effects of pairing students‘ reading with learner tasks. After reviewing many studies, it can be concluded that more reading is better. More specifically, extensive reading of chosen novels at an appropriate level and interest to the students showed important gains in vocabulary. In addition, readings that were supplemented with additional activities that focused on both form and meaning showed an even higher increase in word retention.

MRIs are obtained in research in healthy and clinical populations, and incidental findings have been reported. Most studies have examined adults with variability in parameters of image acquisition and clinical measures available. We conducted a prospective study of youths and documented the frequency and concomitants of incidental findings. Youths (n = 1400) with an age range from 8-23 years were imaged on the same 3T scanner, with a standard acquisition protocol providing 1.0 mm(3) isotropic resolution of anatomic scans. All scans were reviewed by an experienced board-certified neuroradiologist and were categorized into 3 groups: 1) normal: no incidental findings; 2) coincidental: incidental finding(s) were noted, further reviewed with an experienced pediatric neuroradiologist, but were of no clinical significance; 3) incidental findings that on further review were considered to have potential clinical significance and participants were referred for appropriate clinical follow-up. Overall, 148 incidental findings (10.6% of sample) were noted, and of these, 12 required clinical follow-up. Incidental findings were not related to age. However, whites had a higher incidence of pineal cysts, and males had a higher incidence of cavum septum pellucidum, which was associated with psychosis-related symptoms. Incidental findings, moderated by race and sex, occur in approximately one-tenth of participants volunteering for pediatric research, with few requiring follow-up. The incidence supports a 2-tiered approach of neuroradiologic reading and clinical input to determine the potential significance of incidental findings detected on research MR imaging scans.

Fetal magnetic resonance imaging (MRI) is a routinely used tool in prenatal diagnosis; however, there is a lack of studies evaluating incidental findings observed in the mother. This study describes and quantifies incidental findings observed in the mother during fetal MRI. We reviewed all fetal MRI studies at the University of Minnesota Medical Center from February 2008 to September 2014. Two pediatric radiologists retrospectively conducted a consensus evaluation. The maternal findings were categorized into neurologic, gynecologic, urinary, gastrointestinal and musculoskeletal. Hydronephrosis consistent with the stage of pregnancy was recorded but was not included as an abnormal finding. Abnormal findings were classified into three groups, depending on their clinical significance: level I (low), level II (medium) and level III (high). We evaluated 332 pregnant patients with a mean age of 29.3 years and a mean gestational age of 29 weeks. Of these, 55.4% had at least 1 incidental finding, for a total of 262 incidental maternal findings. Of the 262 abnormalities, 113 (43.1%) were neurologic, 69 were gynecologic (26.3%), 36 (13.7%) urinary, 24 (9.2%) gastrointestinal and 20 (7.6%) musculoskeletal. Of the 262 incidental findings, 237 (90.5%) were level I, 24 (9.2%) were level II and 1 (0.4%) was level III. Our results suggest that although the vast majority of incidental maternal findings are benign, more significant findings are still encountered and should be expected. (orig.)

Full Text Available INTRODUCCIÓN: en la actualidad se recomienda que todo paciente con artritis reumatoide (AR antes de iniciarle la terapia anti-TNF sea evaluado para detectar la presencia de infección latente por Mycobacterium tuberculosis (MTB. La prueba cutánea de tuberculina (TST es en la actualidad la única válida para el diagnóstico de infección por MTB en pacientes con infección latente. Sin embargo, la prueba de TST presenta limitaciones. En 2005 la FDA aprobó dos técnicas para el diagnóstico de infección por MTB. Ambas determinan por medio de ELISA la producción de IFN-(IFN-g release assay IGRA en plasma fresco de pacientes sensibilizados. OBJETIVO: el objetivo de este estudio fue establecer qué parámetros clínicos y del tratamiento de pacientes con AR alteran la respuesta a la prueba de PPD y pueden ser útiles como herramientas para la interpretación de la misma en estos pacientes. MÉTODOS: se evaluaron 52 pacientes con diagnóstico de AR del Servicio de Reumatología del Hospital Universitario San Vicente de Paúl, según criterios del American College of Rheumatology (1987. A cada paciente se le aplicó 0,1 ml de PPD por vía intradérmica y 72 horas después se hizo la lectura. A cada paciente se le determinaron características clínicas y de tratamiento y la producción de IFN- ante el estímulo con ESAT-6 y CFP-10 (marcadores diagnósticos de MTB. RESULTADOS: de los 52 pacientes evaluados el 95% eran mujeres con una media de edad de 44 años. El 80% tenían FR positivo (80% con una enfermedad de menos de 10 años de evolución (55%.

2015-04-01
Full Text Available RESUMEN Objetivo: estudio cualitativo que siguió los principios de la teoría fundamentada con el fin de analizar la identidad profesional de docentes de enfermería por medio del análisis de incidentes críticos que más las desestabilizaban. Método: entrevistas semi-estructuradas fueron realizadas a siete enfermeras que actúan como docentes e investigadoras en una universidad privada de Barcelona. Resultados: el material empírico resultante fue organizado en dos categorías: caracterización de los incidentes críticos y reacción de las enfermeras frente a ellos. Conclusión: se concluye que la identidad profesional de estas enfermeras en el campo académico está aún en construcción y que la inexperiencia es el mayor obstáculo que enfrentan para gestionar los incidentes críticos en el trabajo docente.

Full Text Available Fundamento: La insuficiencia cardiaca (IC es un importante problema de salud pública debido a su creciente prevalencia y la descompensación que conlleva un ingreso hospitalario representa un aumento del riesgo de muerte. El objetivo de este trabajo fue comparar varios métodos para modelizar la variable hospitalizaciones y determinar el efecto de los factores asociados con los ingresos hospitalarios en casos incidentes de IC. Método: Se realizó un estudio de cohortes restrospectivo con información extraída de la historia clínica electrónica de Atención Primaria (AP. Se incluyeron pacientes mayores de 24 años que habían realizado al menos 1 consulta en AP durante el año 2006. Se analizaron las hospitalizaciones registradas de casos incidentes de IC entre 2006 y 2010 o hasta su fallecimiento y se compararon modelos de regresión de Poisson, Binomial Negativa (BN, inflados con ceros y de Hurdle para identificar factores asociados a las hospitalizaciones. Resultados: Se identificó a 3.061 personas con IC en una cohorte de 227.984 pacientes. Respecto a los factores asociados con las hospitalizaciones y según el modelo de regresión BN inflado con ceros, los pacientes con valvulopatías (OR=2,01; IC95%: 1,22-3,30 o en tratamiento con antitrombóticos (OR=3,45; IC95%: 1,61-7,42 o diuréticos (OR=2,28; IC95%:1,13-4,58 tuvieron mayor probabilidad de hospitalización. Los factores asociados a una mayor tasa de ingresos fueron tener valvulopatías (IRR=1,37; IC95%: 1,03-1,81 o diabetes mellitus (IRR=1,38, 1,07-1,78 y estar en tratamiento con calcioantagonistas (IRR=1,35; IC95%: 1,05-1,73 o IECAS (IRR=1,43; IC95%:1,06- 1,92.

Pesquisaram-se as bases PubMed, MEDLINE, IPA e LILACS para selecionar estudos publicados entre janeiro de 1990 e dezembro de 2005. Selecionaram-se 33 publicações. Verificou-se que a terminologia supranacional recomendada para descrever incidentes com medicamentos é insuficiente, mas que há consenso de uso das expressões em função do gênero do incidente. O termo Reação Adversa a Medicamento é mais utilizado quando não se verifica intencionalidade. A expressão Evento Adverso a Medicamento foi mais usada quando se descreviam incidentes durante a hospitalização; e Problema Relacionado a Medicamento foi mais utilizada em estudos que avaliaram atenção/cuidados farmacêuticos (uso/falta do medicamento.

2009-01-01
Full Text Available Resumen: En este artículo se presenta y analiza un método de creación de modelos formados por agrupaciones de submodelos locales lineales. La principal novedad es que la ponderación empleada con los submodelos no es la habitual, basada en el estado o parte del mismo sino que se toman exclusivamente señales instantáneas de entrada y salida del sistema. Esta elección simplifica algunos aspectos de la creación del modelo, manteniendo intacta la capacidad de representación, siendo ésta comparada con otras técnicas. La simplificación aludida es importante pues acerca el método a la práctica industrial del control de procesos. La técnica de identificación resultante se ilustra mediante dos casos prácticos: un sistema simulado propuesto por Narendra y el sistema de captación de una planta real de producción de frío a partir de energía solar. En ambos casos se muestran los errores de generalización para la predicción a un paso y para la simulación usando gran cantidad de situaciones. Los resultados indican que es factible el uso del método propuesto como técnica simplificada aplicable en la industria.

Preparation of two-dimensional (2D) heterostructures is important not only fundamentally, but also technologically for applications in electronics and optoelectronics. Herein, we report a facile colloidal method for the synthesis of WOn -WX2 (n=2.7, 2.9; X=S, Se) heterostructures by sulfurization or selenization of WOn nanomaterials. The WOn -WX2 heterostructures are composed of WO2.9 nanoparticles (NPs) or WO2.7 nanowires (NWs) grown together with single- or few-layer WX2 nanosheets (NSs). As a proof-of-concept application, the WOn -WX2 heterostructures are used as the anode interfacial buffer layer for green quantum dot light-emitting diodes (QLEDs). The QLED prepared with WO2.9 NP-WSe2 NS heterostructures achieves external quantum efficiency (EQE) of 8.53 %. To our knowledge, this is the highest efficiency in the reported green QLEDs using inorganic materials as the hole injection layer.

Full Text Available BACKGROUND AND AIM: The present study aimed to assess the nature and prevalence of incidental findings in cone beam computed tomography (CBCT images of oral and maxillofacial patients. METHODS: In this cross-sectional study, 773 CBCT samples were retrieved from archives of a private oral and maxillofacial radiology center. Any findings that were not related to the reason of CBCT request was recorded in forms designed originally for this study. RESULTS: 475 patients out of 773 had at least one incidental finding. It composed about 60% of the patients. The largest frequency of incidental findings were cases of periapical lesions. (n = 189, followed by mucous thickening of maxillary sinus (n = 170, retained root (n = 32, impaction and 3rd molar (n = 26. Other incidental findings were torus (n = 25, dental anomalies (n = 13, vertical root fracture (n = 5, intra bony lesion and periapical pathosis (n = 4 and the lowest frequency was sialoliths (n = 1. CONCLUSION: About half of the subjects have had at least one incidental finding, so the precise review of the CBCT images seems to be necessary.

The (γ, n) cross sections of Se isotopes ( 76 Se, 78 Se) were measured to supply fundamental data for estimating the inverse reaction cross section, i.e., the 79 Se(n, γ) 80 Se cross section. The enriched samples and a reference 197 Au sample were irradiated with laser-Compton scattering (LCS) γ-rays. The excitation function of each (γ, n) cross section was determined for the energy range from each near neutron separation energy to the threshold energy of (γ, 2n) reaction. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS γ-rays. Systematic (γ, n) cross sections for Se isotopes including 80 Se were compared with those calculated by using a statistical model calculation code TALYS. (author)

Full Text Available The effect of enzyme incorporation is analyzed over the yield of grapeseed oil extraction by cold pressing. By this type of process the objective is to preserve grapeseed active compounds and to diminish the environmental impact in comparison to oil extraction conventional methods which use higher temperatures. The enzymatic hydrolysis takes place with a commercial enzyme previous to pressing stage. Its effectiveness is compared to a control without the biocatalyst. An oil extraction yield of 72 % d.b. is obtained with an enzymatic pre-treatment for 4 hours at 50 ºC, and 60 % of moisture, increasing in 26 % the control result. It is concluded that the incorporation of an enzymatic processing would be a feasible alternative to extract grapeseed oil under softener process conditions improving the yield of extraction in comparison to the same type of methodology without an enzyme.Se analiza el efecto de la incorporación de enzimas sobre el rendimiento de extracción de aceite por prensado en frío. Con el prensado en frío se busca preservar los compuestos activos de la pipa de uva y minimizar el impacto medioambiental en comparación con los métodos convencionales de extracción de aceite que utilizan altas temperaturas. El tratamiento enzimático se efectúa previo al prensado con una enzima comercial y su efectividad se compara con un control sin catalizador. Un rendimiento de extracción de aceite del 72 % b.s. se logra con un pre-tratamiento enzimático durante 4 horas a 50 ºC, y 60 % de humedad, superando en un 26 % al control. Se concluye que la incorporación de un tratamiento enzimático sería una alternativa factible para extraer el aceite de pipa de uva bajo condiciones suaves de proceso mejorando el rendimiento de extracción en comparación con el mismo tipo de proceso sin enzima.

La antracnosis causada por Colletotrichum lindemuthianum puede llegar a generar pérdidas hasta del 95% de la producción en fríjol (Phaseolus vulgaris L., por eso es considerada una de las enfermedades más limitantes. Con el presente trabajo se inició un programa de mejoramiento utilizando selección asistida por marcadores. Se usó como parental resistente el cultivar Mesoamericano G2333, para incorporar a fríjoles volubles comerciales de Colombia los genes Co-5 y Co-42 , que confieren resistencia a C. lindemuthianum. Se obtuvieron progenies RC1F1 provenientes de cruces entre G2333 y siete parentales volubles tipo Bola roja y Rojo moteado cultivados en zonas productoras de fríjol de Cundinamarca y Boyacá. La selección de plantas RC1F1 se realizó con los marcadores moleculares SCAR SAB3 y SAS13, ligados a los genes Co-5 y Co-42 , respectivamente. En la evaluación genotípica de 1.271 plantas RC1F1, 608 amplificaron con SAB3 y 603 con SAS13. La segregación para cada marcador se ajustó a la razón 1:1 esperada en pruebas de chi-cuadrado (X2 = 2,38, P= 0,12 para SAB3 y X2 = 3,32, P= 0,07 para SAS13. Un total de 299 plantas RC1F1 amplificaron con ambos SCAR, ajustándose a la razón esperada (X2= 1,11, P= 0,78 y confirmando la segregación independiente. Estas plantas fueron seleccionadas para continuar el programa de mejoramiento, ya que se espera que porten los genes Co-5 y Co-42. Se logró implementar la selección asistida por marcadores para antracnosis, y acelerar la introducción y piramidación de genes de resistencia en fríjol de importancia económica en Colombia.

Los resultados muestran que las operaciones de pesca de esta flota afectan principalmente a los albatros, grupo que concentra el 83,7% de la captura incidental de aves marinas registrada en el período. Esta captura incidental se debe en primera instancia a la presencia del Frente Subtropical del Pacífico Sur, sistema que provoca la sobreposición entre la actividad de esta flota con la distribución espacial de aves marinas durante la fase residente del período no reproductivo. La variabilidad en esta captura incidental estaría fuertemente relacionada a los estímulos visuales (medido mediante el porcentaje de luces químicas y porcentaje de calamar y las condiciones de luminosidad ambiental existentes en los períodos de forrajeo diurno y nocturno de estas aves marinas durante el calado (medido a través del desfase de la hora del ocaso con respecto a la hora de inicio del calado y fase lunar.We analized the relationship between the variability in the rate of seabird bycatch in pelagic longline fishery for swordfish (Xiphias gladius, and several temporary, environmental, spatial and fisheries factors for the fishing period from 2007 to 2009. The results show that the fishing operations of this fleet mainly affect the albatross, group that accounts for 83.7% of the incidental catch of seabirds recorded in the period. This bycatch is due primarily to the presence of the South Pacific Subtropical Front, a system that causes the overlap between the activities of this fleet with the spatial distribution of these seabird species during the resident phase of the nonbreeding period. By the other hand, the variability in bycatch would be strongly linked to visual stimuli (measured by the percentage of

Incidental parotid lesions on F-18 FDG-PET can mimic distant metastasis of underlying malignancy. The prevalence and the clinico-pathologic findings of PET positive parotid lesions have not been known. We investigated how often incidental parotid lesions are found on clinical FDG-PET studies and what the clinico-pathologic characteristics of those parotid lesions are in the present study. We retrospectively reviewed 3,344 cases of FDG-PET which had been obtained in our hospital from May 2003 to Dec 2006. The indications of FDG-PET were: evaluation of known/suspected cancer (n = 3,212) or screening of cancer in healthy subjects (n = 132). Incidental parotid lesion on FDG-PET was defined as an un-expected FDG uptake in one of parotid glands which was not primary target lesion of current FDG/PET. FDG uptake was represented by maximum standardized uptake value (maxSUV). Final diagnosis was made by pathologic analysis or clinical follow-up assessment. Fifteen (0.45% = 15/3,344) incidental parotid lesions were found and they were all benign lesions. The maxSUV ranged from 1.7 to 8.6 (mean ± s.d. = 3.7 ± 1.9). Final diagnoses of the incidental parotid lesions were; Warthin's tumor (n = 2), pleomorphic adenoma (n = 1), other un-specified benign lesion (n 1), and benign lesions under bases of imaging studies (n = 3) and of clinical follow-up (n = 8). All of incidentally found parotid lesions in clinical FDG-PET studies were confirmed as benign lesions with prevalence of 0.45%. Close follow up using PET or CT might be a reasonable approach for determining the nature of incidentally found parotid lesions

Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves' disease were compared to those with multinodular goiter. Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves' disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Early stage thyroid cancer has better survival and prognosis after surgical treatment. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

Full Text Available El objeto de este estudio es el análisis del papel y la función del fr. 241 Bernabé en la exégesis del demiurgo que aparece en el libro II del Comentario al Timeo de Proclo. Este análisis se centra en el primero de los tres demiurgo-Zeus que caracterizan el panteón de este autor, el contenido en la tríada intelectiva Cronos-Rea-Zeus, y plantea la cuestión de por qué opta por el uso de la teología órfica en lugar de la caldaica. Para responder a esta pregunta, el estudio se divide en tres partes: a el análisis de la estructura y el contenido del fr. 241 Bernabé; b el vínculo que establece el Comentario al Timeo entre Orfeo, Pitágoras y Platón; y c la definición que este tratado ofrece el demiurgo y su adaptación a la teología órfica. La conclusión a la que se pretende llegar es que, en este caso concreto, el uso del orfismo viene dado por la adecuación de la segunda creación al concepto de demiurgo defendido por Proclo.

Incidental extra-mammary findings in breast MRI
International Nuclear Information System (INIS)
Alduk, A.M.; Prutki, M.; Stern-Padovan, R.
2015-01-01
Aim: To investigate the frequency, distribution, and nature of incidental extra-mammary findings detected with breast MRI. Materials and methods: Incidental findings were defined as unexpected lesions outside the breast, not previously known or suspected at the time of referral. Five hundred consecutive breast MRI studies performed from June 2010 to September 2012 were reviewed in this retrospective study for which the institutional review board granted approval and waived the requirement for informed consent. MRI findings were compared with subsequent diagnostic procedures in order to differentiate benign from malignant lesions. Results: One hundred and thirty-eight incidental findings were found in 107 of the 500 (21.4%) examined patients. The most common site was the liver (61/138; 44.2%), followed by the lung (24/138; 17.4%), mediastinum (22/138; 15.9%), pleural cavity (15/138; 10.9%), bone tissue (9/138; 6.5%), spleen (3/138; 2.2%), major pectoral muscle (3/138; 2.2%), and kidney (1/138; 0.7%). Twenty-five of the 138 (18.1%) incidental findings were confirmed to be malignant, whereas the remaining 113 (81.9%) were benign. Malignant findings were exclusively detected in patients with known breast carcinoma, whereas incidental findings in patients without a history of carcinoma were all benign. Twenty-five of 100 (24.8%) incidental findings among patients with history of breast cancer were malignant. Conclusion: Although many of incidental findings were benign, some were malignant, altering the diagnostic work-up, staging, and treatment. Therefore, it is important to assess the entire field of view carefully for abnormalities when reviewing breast MRI studies. - Highlights: • 500 consecutive breast MRI studies were retrospectively reviewed. • Incidental findings were found in 107/500 (21.4%) of examined patients. • Incidental extra-mammary findings on breast MRI are common. • Malignant findings were exclusively detected in patients with known breast

The risk of port-site metastasis after laparoscopic removal of incidental gallbladder cancer was previously estimated to be 14-30%. The present study was designed to determine the incidence of port-site metastasis in incidental gallbladder cancer in the modern era (2000-2014) versus the historic era (1991-1999). We also investigated the site of port-site metastasis. Using PRISMA, a systematic review was conducted to identify papers that addressed the development of port-site metastasis after laparoscopic resection of incidental gallbladder cancer. Studies that described cancer-specific outcomes in ≥5 patients were included. A validated quality appraisal tool was used, and a weighted estimate of the incidence of port-site metastasis was calculated. Based on data extracted from 27 papers that met inclusion criteria, the incidence of port-site metastasis in incidental gallbladder cancer has decreased from 18.6% prior to 2000 (95% confidence interval 15.3-21.9%, n = 7) to 10.3% since then (95% confidence interval 7.9-12.7%, n = 20) (P extraction site is at significantly higher risk than nonextraction sites. The incidence of port-site metastasis in incidental gallbladder cancer has decreased but remains high relative to other primary tumors. Any preoperative finding that raises the suspicion of gallbladder cancer should prompt further investigation and referral to a hepato-pancreato-biliary specialist. Copyright © 2016 Elsevier Inc.

Full Text Available Investigations show that distrust towards head figures has a particularly negative effect on organizational dynamics. Because of this, the main types of behavior associated with distrust in nursing professionals with leadership duties have been identified, examining which aspect of reliability is most frequently related to distrust. Based on an analysis of 61 critical incidents, selected from 90 hospital employees, the most frequently mentioned behavior types related to distrust were "Public Abuse", "Not giving permission for time off for a special occasion" and especially an erosion of trustworthiness in the leader's integrity dimension. The implications of these findings are discussed, so that nursing professionals can avoid the development of distrust in interpersonal relationships and damage to the appropriate functioning of health services.Investigaciones muestran que la desconfianza hacia las jefaturas tiene un especial efecto negativo en la dinámica organizacional. Por ello, se identificaron los principales tipos de conductas asociadas a desconfiar de profesionales de enfermería con cargo de jefatura y se examinó cual dimensión de la confiabilidad se relaciona más frecuentemente con la desconfianza. Basándose en el análisis de 61 incidentes críticos obtenidos de 90 funcionarios de un hospital, se identificó que los tipos de conducta que generaban más frecuentemente mención de desconfianza fueron "Maltrato en público" y "No dar un permiso para algo especial"; y que se erosiona especialmente la confiabilidad del jefe en la dimensión integridad. Se discuten las implicancias de estos hallazgos para que los profesionales de enfermería que ejercen liderazgo eviten el surgimiento y desarrollo de la desconfianza en sus relaciones interpersonales y no perjudiquen el apropiado funcionamiento de los servicios de salud.Algumas investigações mostram que a desconfiança nos chefes produz um efeito especialmente negativo nas din

Hopping conduction in gamma-irradiated InSe and InSe:Sn single crystals

Full text : The semiconductive InSe layer compound is characterized by a strong covalent bond inside the layers and a weak Van der Waals bonding between them. It was shown that across the layers of InSe single crystals at low temperatures (T ≤ 200 K) at direct current (dc) hopping conduction through localized states near the Fermi level takes place. The results of dc-conductivity of gamma-irradiated p-InSe and n-InSe : Sn layer single crystals have been presented in this work. ρ-InSe single crystal specimens grown by the Bridgman method were used in the experiments. Plates of the crystals under study were obtained by cleaving along the layers of single crystal ingots. The single-crystal InSe samples for electric measurements had the form of planar capacitors normal to the C axis of the crystals, with silver-paste electrodes. The thickness of the InSe samples was 300 mkm. Co 60 serves as the source of irradiation with energy of gamma-quantum equal to 1.3 MeV. The electric properties of non-irradiated and gamma-irradiated InSe crystals were measured under the same conditions. It is revealed that InSe and InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals exhibit a variable range hopping conduction along a normal to their natural layers at temperatures T≤200 K in a dc electric field. From experimental data the parameters of localized states of p-InSe and n-InSe : Sn were calculated before and after gamma-irradiation. It is revealed that gamma-irradiation of p-InSe and n-InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals leads to significant change of localized states parameters. After gamma-irradiation the density of states near the Fermi level increased, but their energy spread and the average jump distance decreased. The concentrations of radiated defects were estimated in p-InSe (5.18*10 1 7 sm - 3) and n-InSe : Sn (2.5*10 1 7 - 2.7*10 1 8 sm - 3) single crystals. The present results demonstrate that gamma-irradiation offers the possibility of tuning

Se hace necesario revisar la existencia de segmentos, lo que se logra teniendo un número grande de consumidores en la evaluación para que sean válidos estadísticamente. El consumidor moderno es exigente y busca nuevas opciones para alimentarse y mantener su salud. Actualmente, ha habido un gran auge de productos bajos en calorías y reducidos en grasa, dentro de los cuales se encuentran las ensaladas, tanto precortadas, como de vegetales cocidos que pueden llevar un aderezo, como mayonesa, que se conocen como ensaladas frías. El objetivo fue utilizar estudios de consumidor para reducir la grasa y evaluar la vida útil de ensaladas frías por medio de estudios de consumidor. El contenido graso de las ensaladas se redujo al sustituir mayonesa con yogurt natural, en dos tipos de ensalada: de papa y de repollo. Se utilizó 0 %, 50,0 % y 70,0 % de yogurt en lugar de mayonesa en cada una y se evaluó la aceptación de las tres versiones de cada ensalada en diferentes segmentos de consumidores. Una vez que se definió esta sustitución de yogurt, las dos ensaladas se almacenaron por 9 días a temperatura de refrigeración para determinar su vida útil. Se hizo una prueba de aceptación de las ensaladas que correspondió a los días 1, 3, 4, 7 y 9 del almacenamiento. Se determinó cuál fue el tiempo máximo de almacenamiento donde todavía no había disminuido el agrado. Se encontró que en la ensalada de papa se pudo reducir la mayonesa, sustituyéndola por yogurt, en un 50,0 % y en la de repollo en un 70,0 %. Se clasificó la ensalada de papa como liviana y su vida útil fue de 7 días y la de repollo como baja en grasa y su vida útil fue de 6 días.

Full Text Available Este artículo presenta algunos resultados de una investigación realizada en la Universidad Nacional de General Sarmiento sobre el proceso inclusión/exclusión en la escuela secundaria del Gran Buenos Aires. Su punto de partida fue la pregunta, Desde la perspectiva de los jóvenes "¿Cuales son aquellos aspectos de la dinámica escolar que se constituyen en facilitadores o en obstáculos de la permanencia (con sentido en la escuela?". Desde un enfoque cualitativo, que asume la importancia de la experiencia subjetiva de los individuos en la construcción del mundo social, la investigación construyó un acercamiento progresivo a la voz y la mirada de los actoresde este proceso. Se han desarrollado entrevistas biográfico narrativas sobre trayectorias escolares, entrevistas en profundidad y grupos focales incluyendo diferentes técnicas de recolección de información como la foto-elucidación. El universo de este estudio estuvo conformado por jóvenes del conurbano bonaerense que dejaron de participar de la experiencia escolar formal entre los años 2006 y 2008. Entre los resultados más relevantes de la investigación, podemos señalar la percepción de una escuela que pone en marcha modos de exclusión "instrumentales", la naturalización de las prácticas escolares, la identificación por parte de los jóvenes de "incidentes críticos" que los alejan de la escuela y el lugar que ocupa en la vida de los jóvenes el grupo de pares como factor que contribuye a la permanencia en la escuela pero que al mismo tiempo es significado como obstáculo que impide el aprendizaje y contribuye a la exclusión.

How could disclosing incidental information from whole-genome sequencing affect patient behavior?
Christensen, Kurt D; Green, Robert C
2013-06-01
In this article, we argue that disclosure of incidental findings from whole-genome sequencing has the potential to motivate individuals to change health behaviors through psychological mechanisms that differ from typical risk assessment interventions. Their ability to do so, however, is likely to be highly contingent upon the nature of the incidental findings and how they are disclosed, the context of the disclosure and the characteristics of the patient. Moreover, clinicians need to be aware that behavioral responses may occur in unanticipated ways. This article argues for commentators and policy makers to take a cautious but optimistic perspective while empirical evidence is collected through ongoing research involving whole-genome sequencing and the disclosure of incidental information.

Wuennemann, F.; Rehnitz, C.; Weber, M.A.
2017-01-01
Increasing numbers of conventional X-rays, computed tomography and magnetic resonance imaging in the inpatient, outpatient and scientific routine leads to an increasing number of incidental findings. The correct interpretation of these incidental findings with respect to the relevance and the evaluation concerning further work-up is an important task of radiologists. Description of common incidental findings in musculoskeletal imaging and their clinical classification. A PubMed literature search was performed using the following terms: incidental findings, population-based imaging, musculoskeletal imaging, non-ossifying fibroma, enchondroma, osteodystrophia deformans, chondrosarcoma, fibrous dysplasia, simple bone cyst, unicameral bone cyst, solitary bone cyst, aneurysmal bone cyst, vertebral hemangioma, bone island, osteopoikilosis, Tarlov cyst and diffuse idiopathic skeletal hyperostosis (DISH).

To evaluate the value of adding T2- and diffusion-weighted imaging (DWI) to the BI-RADS registered classification in MRI-detected lesions. This retrospective study included 112 consecutive patients who underwent 3.0T structural breast MRI with T2- and DWI on the basis of EUSOMA recommendations. Morphological and kinetic features, T2 signal intensity (T2 SI) and apparent diffusion coefficient (ADC) findings were assessed. Thirty-three (29.5 %) patients (mean age 57.0 ± 12.7 years) had 36 primarily MRI-detected incidental lesions of which 16 (44.4 %) proved to be malignant. No single morphological or kinetic feature was associated with malignancy. Both low T2 SI (P = 0.009) and low ADC values (≤0.87 x 10{sup -3} mm{sup 2}s{sup -1}, P < 0.001) yielded high specificity (80.0 %/80.0 %). The BI-RADS classification supplemented with information from DWI and T2-WI improved the diagnostic performance of the BI-RADS classification as sensitivity remained 100 % and specificity improved from 30 % to 65.0 %. The numbers of false positive lesions declined from 39 % (N = 14) to 19 % (N = 7). MRI-detected incidental lesions may be challenging to characterize as they have few specific malignancy indicating features. The specificity of MRI can be improved by incorporating T2 SI and ADC values into the BI-RADS assessment. (orig.)

To evaluate the significance of incidentally detected breast lesions on a chest CT scan. Thirty-six incidental breast lesions in 26 patients were detected on a chest CT scan and were correlated with breast sonography, retrospectively. Among them, twenty-four breast lesions in 20 patients that were correlated with chest CT and sonography were available to pathology or follow up sonography. The CT findings were compared with sonographic findings according to the pathologic results. Incidentally detected breast lesions on a chest CT scan were correlated with sonography in 86% (31/36). Among 24 lesions that were available to pathology or follow up sonography, seven (29.2%) lesions were malignant and 17 (70.8%) lesions were benign. CT revealed a significant difference between benign and malignant lesions in terms of shape and margin (p = 0.007; p = 0.008, respectively). The CT findings were well correlated with sonographic findings in shape and margin (p = 0.001, respectively). Incidentally detected breast lesions on chest CT can be correlated with sonography. An irregular shape or a non-circumscribed margin of breast lesions on a CT scan can be considered as a suggestive sign of malignancy.

Homoepitaxial and heteroepitaxial ZnSe metal-semiconductor-metal (MSM) photodetectors were both fabricated and characterized. It was found that homoepitaxial ZnSe MSM photodetector could provide us smaller dark current and large photocurrent. With an incident wavelength of 448 nm, it was found that the maximum responsivities for the homoepitaxial and heteroepitaxial ZnSe photodetectors were 0.128 and 0.045 A/W, which corresponds to a quantum efficiency of 36 and 12%, respectively. Furthermore, it was found that we achieved the minimum noise equivalent power (NEP) of 7.6 x 10 -13 W and the maximum normalized detectivity (D *) of 9.3 x 10 11 cm Hz 0.5 W -1 from our homoepitaxial ZnSe photodetector. In contrast, NEP and D * of the heteroepitaxial ZnSe photodetector were 2.9 x 10 -12 W and 2.44 x 10 11 cm Hz 0.5 W -1 , respectively

Preparation and electrical properties of heterostructures nCdSe-pInAs
International Nuclear Information System (INIS)
Gospodinov, M.; Dobreva, S.
1993-01-01
Single crystals of InAs n-type produced by the Czochralski method have been used as a base material for substrates; CdSe in powder form with a purity 99.999% - as a source for epitaxy. The optimal layers growth conditions are obtained by a series of experiments. Best results are obtained at: source temperature 650-680 o C, substrate temperature 550-570 o C, difference between the source and substrate temperature 100-110 o C, hydrogen flow rate 1 l/h, growth time 1-8 h, distance between the source and the substrate 2 mm. The voltage-current characteristics of an iso type heterojunction nInAs [111] - nCdSe [0001] are measured at liquid nitrogen temperature. Non-symmetry of the characteristics are observed which distinguishes them from those of varistors. The current/voltage dependence in forward direction is different from the exponential one, whereby in reverse direction of the voltage it is almost exponential. The rectifying properties of the heterojunction in forward voltage mode are explained. It is shown that the heterojunction nInAs-nCdSe appears like a p-n heterojunction. For higher reverse voltages a weak breakdown is observed. The mechanism of this breakdown is explained by the tunneling of electrons from the conduction band of InAs towards the conduction band of CdSe as well as by surface leaking effects. The barrier in CdSe is determined by measurement of the voltage-capacity characteristics. It is shown that the capacity changes only in the reverse direction which means that the barrier is located on the side of CdSe. It is assumed that due to the very small difference in the lattice constants of CdSe and InAs [0.033], the density of the states on the boundary is relatively low (10 -11 - 10 -12 ) cm -2 . So, the boundary states exercise a weak influence on the energetic zone diagram. 3 figs., 9 refs

Superconductivity in the ferecrystals (PbSe){sub 1.14}(NbSe{sub 2}){sub n}
Energy Technology Data Exchange (ETDEWEB)
Grosse, Corinna; Chiatti, Olivio; Fischer, Saskia F. [Novel Materials Group, Humboldt-Universitaet Berlin (Germany); Alemayehu, Matti B.; Falmbigl, Matthias; Johnson, David C. [Department of Chemistry, University of Oregon, Eugene, OR (United States)

The ferecrystals (PbSe){sub 1.14}(NbSe{sub 2}){sub n} are artificially layered materials consisting of n NbSe{sub 2} single-layers stacked alternately with atomic double layers of PbSe. NbSe{sub 2} is a transition metal dichalcogenide with interesting electrical properties such as superconductivity and charge density waves. The influence of turbostratic disorder, a random rotation between the NbSe{sub 2} and PbSe layers, on the superconducting transition temperature has been unknown so far. We investigate the structural and temperature-dependent electrical properties of the ferecrystals (PbSe){sub 1.14}(NbSe{sub 2}){sub n} by means of scanning transmission electron microscopy, X-ray diffraction, in-plane resistivity and Hall measurements and compare them to those of analogous non-disordered misfit layer compound (MLC) polymorphs. We observe a superconducting transition in the resistivity of the ferecrystals. The transition temperatures are reduced by up to 55 % with respect to the analogous MLC polymorphs. This indicates that turbostratic disorder substantially weakens the electron-phonon coupling in (PbSe){sub 1.14}(NbSe{sub 2}){sub n}. We discuss the results of the structural and electrical properties of the ferecrystals with respect to their MLC analogues and also with respect to ultra-thin NbSe{sub 2} layers.

To evaluate the nature and imaging appearance of incidental enhancing breast lesions detected on a routine contrast-enhanced chest CT. Twenty-three patients with incidental enhancing breast lesions on contrast-enhanced chest CT were retrospectively reviewed. The breast lesions were reviewed by unenhanced and enhanced CT, and evaluated by observing the shapes, margins, enhancement patterns and backgrounds of breast lesions. A histopathologic diagnosis or long-term follow-up served as reference standard. Sixteen (70%) patients had malignant breast lesions and seven (30%) had benign lesions. In 10 patients, the breast lesions were exclusively detected on contrast-enhanced CT. Using unenhanced CT, breast lesions with fi broglandular backgrounds were prone to be obscured (p < 0.001). Incidental primary breast cancer showed an non-significant trend of a higher percentage irregular margin (p = 0.056). All of the four incidental breast lesions with non-mass-like enhancement were proven to be malignant. Routine contrast-enhanced chest CT can reveal sufficient details to allow for the detection of unsuspected breast lesions, in which some cases may be proven as malignant. An irregular margin of incidental enhancing breast lesion can be considered a suggestive sign of malignancy

Full Text Available The techniques of differential thermal analysis are frequently employed to study the kinetics of the transformation reactions and, in particular, the crystallization of the glassy alloys. The corresponding thermal data can be analyzed by the Kissinger method, which was originally derived for the study of homogeneous reactions. The consensus in the literature, in several decades, was that such applications (i.e. to heterogeneous solid state transformations of the Kissinger method are not valid. In the present work the principal objections to the mentioned applications are addressed and alternative derivations of theoretical results are provided. These results demonstrate that the Kissinger method is valid for heterogeneous reactions of the type described by Johnson-Mehl-Avrami equation in the isothermal case. Also the isothermal and non-isothermal data on crystallization of the Cu0.10As0.40Se0.50 glassy alloy are given. The experimental results and the discussion carried out here, help to clarify the effects of incubation time in non-isothermal transformation kinetics and provide a further demonstration of validity of the generalized Johnson-Mehl-Avrami theory for the description of heterogeneous solid state transformations.Las técnicas de análisis térmico diferencial se emplean con frecuencia para estudiar la cinética de las reacciones de transformación y, en particular la de la cristalización de aleaciones vítreas.

Alternative syntheses of [73,75Se]selenoethers exemplified for homocysteine[73,75Se]selenolactone
International Nuclear Information System (INIS)
Ermert, J.; Blum, T.; Hamacher, K.; Coenen, H.H.
2001-01-01
The present work describes two radiosynthetic pathways to prepare homocysteine[ 75 Se]selenolactone 1 starting from n.c.a. [ 75 Se]selenite 2. It was achieved either by alkylation reaction of n.c.a. methyl[ 75 Se]selenide 4 or by hydrolysis of alkylated 1,3-dicyclohexyl[ 75 Se]selenourea 11. N.c.a. methyl[ 75 Se]selenide 4 is available using sulfur as non-isotopic carrier. However, the radiochemical yield of the substitution of 2-tert.-butoxycarbonylamino-4-bromobutyric acid ethylester 5 with n.c.a. methyl-[ 75 Se]selenide is only in the range of 15%-20%. Birch reduction of protected n.c.a. [ 75 Se]selenomethionine 6 formed leads to a RCY of 5%-10% homocysteine[ 75 Se]selenolactone 1. Alternatively, the synthesis of homocysteine[ 75 Se]selenolactone 1 is possible by hydrolysis of the corresponding [ 75 Se]selenouronium salt 11 available by addition of 2-tert.-butoxycarbonylamino-4-bromobutyric acid ethylester 5 to 1,3-dicyclohexyl[ 75 Se]selenourea 10. A method was developed for the synthesis of 1,3-dicyclohexyl[ 75 Se]selenourea 10 by addition of c.a. [ 75 Se]SeH 2 to 1,3-dicyclohexylcarbodiimide, which leads to 20%-30% RCY of c.a. homocysteine[ 75 Se]selenolactone 1. (orig.)

The temperature dependences of physical parameters (the conductivity and the Hall constant) are experimentally investigated for pure indium-selenide (n-InSe) crystals and those lightly doped with rareearth elements (gadolinium, holmium, and dysprosium). It is established that the obtained results depend on the origin of the samples under investigation and prove to be contradictory for different samples. The obtained experimental results are treated taking into account the presence of chaotic large-scale defects and drift barriers caused by them in these samples.

Dynamical properties and their strain-dependence of ZnSe(ZnSe:N: Zinc-blende and wurtzite
Directory of Open Access Journals (Sweden)
Dandan Wang
2014-06-01
Full Text Available The lattice dynamical properties of ZnSe and ZnSe with substitutional N incorporation(ZnSe:N are investigated in both the zinc-blend(ZB and wurtzite(WZ structures using first-principles calculations. The optical phonon modes of ZB-ZnSe at the Γ-point locate at 250 cm−1 for LO and 213 cm−1 for TO. The characteristic E2 phonon modes at about 50 cm−1 and the E1 and another E2 phonon modes around 200 cm−1 of WZ-ZnSe are suggested to be the fingerprint for distinguishing the two polytypes of ZnSe. For substitutional N incorporated ZnSe, the N incorporation introduces three new high energy modes above 500 cm−1, and the splitting of them is much larger in the WZ phase than that in ZB phase. The strain dependence of phonon frequency which could be useful for corresponding spectroscopic strain characterization are also studied. The simple linear dependence is determined for ZB-ZnSe, while the situation for WZ-ZnSe looks more complicated.

Full Text Available Introduction: Cancer wounds need regular dressing; else they develop infection, foul odor, and in extreme cases, maggots. Patients resist dressing due to the severe incidental pain during dressing. Intranasal ketamine was tried as an analgesic to reduce this incidental pain. Materials and Methods: Twenty patients with wounds requiring regular dressing were selected; these patients had a basal pain score of 4/10 and incidental pain score of 7/10 during four consecutive dressings. Ketamine 0.5 mg/kg was administered transmucosally 10 min before dressing, and pain scores, hemodynamic parameters, and sedation were recorded for up to 2 h in six consecutive dressings. Results: Ketamine produced a significant reduction in incidental pain without any hemodynamic changes or sedation. Conclusion: Ketamine appears to be a safe and effective analgesic when used intranasally for incidental pain.

Full Text Available An experimental methodology was generated for understanding the theoretical and practical concepts inherent to cold flat rolling. Aluminium slabs about 100 mm length, 9 mm thickness with different widths: 10 and 30 mm were rolled. A constant 0.3 mm thickness reduction step was performed in order to achieve a thickness reduction greater than 80 %. In the Abaqus® commercial software, a mathematical model was implemented in order to obtain a greater understanding concerning how the process variables affect the fields of stresses and strains that are not observed experimentally. It was found, by mathematical simulation, that a superficial hardening in the plates was produced and the deformation obtained is heterogeneous, which is corroborated physically. Keywords: Flat rolling; 6063 Aluminium; Data acquisition system; Simulation Se generó una metodología experimental para el entendimiento teórico-práctico de los conceptos del proceso de laminación plana en frío. Se laminaron placas de aluminio de aproximadamente 100 mm de longitud y 9 mm de espesor, a diferentes anchos: 10 y 30 mm. Se seleccionó una razón de reducción constante de 0.3 mm para cada paso de laminación, hasta lograr una reducción superior al 80 % en espesor. Se implementó un modelo matemático en el paquete comercial Abaqus® con el fin de obtener un mayor entendimiento sobre la influencia de las variables del proceso (fuerza aplicada y dimensiones de las probetas en los campos de esfuerzos y deformaciones que, experimentalmente, no se pueden observar. Se encontró, mediante la simulación matemática, que se produce un endurecimiento superficial en las placas y que la deformación obtenida es heterogénea, lo cual se corrobora físicamente.

Zhang, Xiaoxuan; Feng, Dan; He, Jiaqing; Zhao, Li-Dong
2018-02-01
As an intrinsic p-type semiconductor, BiCuSeO has been widely researched in the thermoelectric community, however, n-type BiCuSeO has not been reported so far. In this work, we successfully realized n-type BiCuSeO through carrying out several successive efforts. Seebeck coefficient of BiCuSeO was increased through introducing extra Bi/Cu to fill the Bi/Cu vacancies that may produce holes, and the maximum Seebeck coefficient was increase from +447 μVK-1 for undoped BiCuSeO to +638 μVK-1 for Bi1.04Cu1.05SeO. The Seebeck coefficient of Bi1.04Cu1.05SeO was changed from p-type to n-type through electron doping through introducing Br/I in Se sites, the maximum negative Seebeck coefficient can reach ∼ -465 μVK-1 and -543 μVK-1 for Bi1.04Cu1.05Se1-xIxO and Bi1.04Cu1.05Se1-xBrxO, respectively. Then, after compositing Bi1.04Cu1.05Se0.99Br0.01O with Ag, n-type BiCuSeO can be absolutely obtained in the whole temperature range of 300-873 K, the maximum ZT 0.05 was achieved at 475 K in the Bi1.04Cu1.05Se0.99Br0.01O+15% Ag. Our report indicates that it is possible to realize n-type conducting behaviors in BiCuSeO system.

Full Text Available Focus on form instruction is a kind of instruction that draws students, attention to linguistic elements as they arise incidentally in meaning based instruction. There are different types of focus on form instruction. The present study was designed to investigate the effect of incidental focus on form on grammatical accuracy among Iranian L2 learners. Eighty learners from Sahand language Institute in Miandoab after taking grammatical judgment test which was administered to homogenize them, were placed in two control and experimental groups. Learners in experimental group received feedback through recasting during retelling the reading passage according to principles of Jigsaw task. But learners in control group did not receive any feedback. After treatment, which lasted for eight sessions, post-test was given to both control and experimental groups to observe the difference resulted from the treatment. To be sure about the significance of the difference between post-test means of both groups, a t-test was used. The results at the end supported the hypotheses of the study and positive effect of incidental focus on form on grammatical accuracy of L2 learners. After that, for the purpose of analyzing the effect of incidental focus on form on accuracy of pronouns, tenses, articles and propositions separately, other tests (pronoun, article, tense, proposition tests was given to the learners in both control and experimental groups. The data collected was computed through t-test which revealed that the effect of incidental focus on form on grammatical accuracy of articles is greater than pronouns and tenses but incidental focus on form didn’t have any effect on accuracy of propositions. Pedagogical implications have been discussed. Keywords: Focus on form, Incidental focus on form, recast, task, Accuracy

Full Text Available ResumenEn la presente investigación se analizan los incidentes racistas ocurridos en los partidos de liga del fútbol profesional español en 1ª y 2ª división durante las temporadas 2004-05 y 2005-06. Para realizar dicho análisis se han empleado tres fuentes oficiales: 1. Actas de la Comisión Nacional contra la Violencia en los Espectáculos Deportivos, 2. Informes trimestrales realizados por la Oficina Nacional del Deporte perteneciente a la Dirección General de la Policía, y 3. Actas arbitrales. Los resultados muestran cómo el número total de incidentes racistas se mantuvo prácticamente constante en ambas temporadas aunque en 2ª división el número de incidentes se duplicó. En cuanto a la tipología de los incidentes recogidos, el 79% hace relación a conductas e insultos racistas mientras que el 21% restante se refiere a la exhibición de simbología de carácter racista. También se muestran datos de los clubes cuyos seguidores han ocasionado más incidentes racistas; cuántos de esos incidentes fueron protagonizados por grupos ultras; así como el número de personas implicadas y las propuestas de sanción realizadas por la Comisión Nacional contra la Violencia.

Chen, Xiaoshuang; Liu, Guangbo; Hu, Yunxia; Cao, Wenwu; Hu, PingAn; Hu, Wenping
2018-01-01
The hybrid n-type 2D transition-metal dichalcogenide (TMD)/p-type oxide van der Waals (vdW) heterojunction nanosheets consist of 2D layered MoSe2 (the n-type 2D material) and MoO x (the p-type oxide) which are grown on SiO2/Si substrates for the first time via chemical vapor deposition technique, displaying the regular hexagon structures with the average length dimension of sides of ˜8 μm. Vertical MoSe2-MoO x p-n heterojunctions demonstrate obviously current-rectifying characteristic, and it can be tuned via gate voltage. What is more, the photodetector based on vertical MoSe2-MoO x heterojunctions displays optimal photoresponse behavior, generating the responsivity, detectivity, and external quantum efficiency to 3.4 A W-1, 0.85 × 108 Jones, and 1665.6%, respectively, at V ds = 5 V with the light wavelength of 254 nm under 0.29 mW cm-2. These results furnish a building block on investigating the flexible and transparent properties of vdW and further optimizing the structure of the devices for better optoelectronic and electronic performance.

Institutional review board approval and written informed consent were obtained for this prospective HIPAA-compliant study. A total of 247 subjects (141 with NF1, 55 with NF2, 51 with schwannomatosis; 132 women (53.5%); mean age, 41 years, range, 18-97 years) underwent WBMRI using coronal STIR (TR/TE: 4190/111 ms, TI: 150 ms) and T1-weighted images (TR/TE: 454/10 ms), 10-mm slice thickness, imaging time ∝40 min. Images were reviewed for the presence of incidental findings, outside of nerve sheath tumors. The presence of scoliosis was recorded and curve morphology was assessed and quantified. Incidental findings other than scoliosis were recorded in 104/247 (42%) patients, most often affecting the musculoskeletal system (65/247 patients, 26%). We found 16/247 (6.5%) significant incidental findings likely to affect clinical management, including avascular necrosis of bone in eight patients (five with NF2), eight insufficiency fractures, and four non-neurogenic neoplasms (Hodgkin's lymphoma, liposarcoma, dermoid cyst, large uterine myoma requiring excision). Scoliosis was seen in 50/247 patients (20%), including 8/55 with NF2 (15%) and 11/51 with schwannomatosis (22%). Incidental findings in the neurofibromatoses frequently involve the skeleton. Given the relatively high incidence of unsuspected osteonecrosis and stress fractures, close attention to the skeleton on WBMRI is advised. In addition, knowledge of common incidental findings can help clinicians prepare patients who undergo WBMRI for potential unexpected findings. (orig.)

Procedimiento para la obtención de cargas últimas de arcos de perfiles conformados en frío

Cifuentes-Bulté, H.
2015-09-01
Full Text Available This paper deals with a new methodology for the estimation of the strength of circular arches with cold-formed trapezoidal section. These cover elements, mainly subjected to compression stress and with circular curvature should be dimensioned taking into account the possibility of buckling instability. Currently, no standard describes a method for calculating the buckling consideration of curved elements. The methodology proposed herein shares the same philosophy of the European buckling curves method established in the Eurocodes. Thus, an experimental coefficient considering the effects of buckling and geometrical and mechanical imperfections depending on the slenderness of the considered arch have been obtained. For this, it was necessary to determine the experimental strength of at least three arcs, which radius and spans are sufficiently differentiated.En este trabajo se presenta una metodología de cálculo para la determinación de la carga última de arcos circulares con perfiles trapezoidales conformados en frío. Estos elementos de cubierta, sometidos fundamentalmente a esfuerzos de compresión y de directriz curva, deben ser dimensionados teniendo en cuenta la inestabilidad por pandeo. Actualmente, ninguna normativa describe un procedimiento de cálculo para la consideración del pandeo en elementos curvos. La metodología aquí planteada se basa en la filosofía de las curvas europeas de pandeo establecidas en los Eurocódigos. Así, se ha obtenido un coeficiente reductor empírico que considera los efectos del pandeo conjuntamente con imperfecciones geométricas y mecánicas en función de la esbeltez del arco considerado. Para ello, es necesario determinar la carga última experimental de al menos tres arcos, cuyos radios y luces se encuentren lo suficientemente diferenciados.

Reciprocal within-day associations between incidental affect and exercise: An EMA study.
Emerson, Jessica A; Dunsiger, Shira; Williams, David M
2018-01-01
Previous research suggests that how people feel throughout the course of a day (i.e. incidental affect) is predictive of exercise behaviour. A mostly separate literature suggests that exercise can lead to more positive incidental affect. This study examines the potential reciprocal effects of incidental affect and exercise behaviour within the same day. Fifty-nine low-active (exercise exercise promotion programme. Ecological momentary assessment was used to record self-reported exercise sessions in real time and incidental affective valence (feeling good/bad) as assessed by the 11-point Feeling Scale at random times throughout the day. Use of a within-subjects cross-lagged, autoregressive model showed that participants were more likely to exercise on days when they experienced more positive incidental affect earlier in the day (b = .58, SE = .10, p exercised (b = .26, SE = .03, p exercising are reciprocally influential within the course of a day.

Full Text Available BackgroundGallbladder cancer is sometimes incidentally uncovered following cholecystectomy for gallstones diseases. The supposed highly variable prevalence of incidental gallbladder cancer through our country is unknown.ObjectiveTo explore the prevalence of incidental gallbladder cancer in our tertiary-care hospital.MethodsA cross-sectional study was carried out on patients who consecutively underwent cholecystectomy due to gallstones disease at Faculdade Pernambucana de Saúde, Instituto de Medicina Integral Professor Fernando Figueira - FPS/IMIP, from January, 2007 to December, 2010. Data on incidental gallbladder cancer patients were explored for prevalence estimation and description of our experience with the management of this malignancy.ResultsOur analysis involved 2018 patients with a marked predominance of women (n=1.697; 84.1% over men (n=321; 15.9%. The 3-year prevalence estimate of 0.34% was recorded for incidental gallbladder cancer in our sample. Regarding tumor staging, there were 1 T1a, 1 T1b, and 5 T2 adenocarcinoma tumors. Laparoscopic cholecystectomy alone was performed for the T1a tumor, and additional radical surgery was performed in five others. One patient presented metastatic disease at the time of repeat surgery. The final pathology revealed residual/additional disease in all T2 tumors after radical surgery whereas the T1b patient underwent a salvage Whipple’s procedure due to a secondary distal cholangiocarcinoma. The patient with T1a tumor is alive after 3-year follow-up but all of the others died because of disease recurrence/progression up to 12 months.ConclusionThis study confirms the poor prognosis of Gallbladder cancer even when incidentally diagnosed following cholecystectomy and supposes a 3-year prevalence estimate of 0.34% for incidental gallbladder cancer in our Center from Pernambuco State, Brazil.

Variability in radiologists' reporting styles and recommendations for incidental thyroid nodules can lead to confusion among clinicians and may contribute to inconsistent patient care. Our aim was to describe reporting practices of radiologists for incidental thyroid nodules seen on CT and MR imaging and to determine factors that influence reporting styles. This is a retrospective study of patients with incidental thyroid nodules reported on CT and MR imaging between January and December 2011, identified by text search for "thyroid nodule" in all CT and MR imaging reports. The studies included CT and MR imaging scans of the neck, spine, and chest. Radiology reports were divided into those that mentioned the incidental thyroid nodules only in the "Findings" section versus those that reported the incidental thyroid nodules in the "Impression" section as well, because this latter reporting style gives more emphasis to the finding. Univariate and multivariate analyses were performed to identify radiologist, patient, and nodule characteristics that influenced reporting styles. Three hundred seventy-five patients met the criterion of having incidental thyroid nodules. One hundred thirty-eight (37%) patients had incidental thyroid nodules reported in the "Impression" section. On multivariate analysis, only radiologists' divisions and nodule size were associated with reporting in "Impression." Chest radiologists and neuroradiologists were more likely to report incidental thyroid nodules in the "Impression" section than their abdominal imaging colleagues, and larger incidental thyroid nodules were more likely to be reported in "Impression" (P ≤ .03). Seventy-three percent of patients with incidental thyroid nodules of ≥20 mm were reported in the "Impression" section, but higher variability in reporting was seen for incidental thyroid nodules measuring 10-14 mm and 15-19 mm, which were reported in "Impression" for 61% and 50% of patients, respectively.

Free recall memory deficits are common at early stages of Parkinson's disease (PD). As most studies have used intentional memory tasks, there is little information on how non-intentional, incidental encoding conditions affect memory performance in PD. We studied possible differences between PD patients and controls on free recall using incidental and intentional visual memory tasks. Free recall was examined in relation to attentive/executive functioning and subjective memory complaints. A total of 29 non-demented, medicated PD patients (age 60, disease duration 19 months) and 29 healthy controls (age 61) participated in the study. Incidental free recall was studied using a memory-modification of the Boston naming test (Memo-BNT) and intentional free recall with the 20 Objects test. There was a significant main effect for group due to worse free recall performances in the PD group. No statistically significant interaction between group and encoding condition was observed. The free recall deficit in the PD group was related to cognitive/psychomotor slowing, but not to attentive/executive task demands, or to subjective memory complaints. The results indicate that PD patients are impaired on free recall irrespective of encoding condition.

This effect is attributed primarily to the alpha-particle irradiation from the thermal-neutron capture of boron-10.

L' e ffe t globa l de l ' irradiation par les neutrons thermiques est fonction du nombre de neutrons incidents par centimetre carre et par unite de temps. Comme le flux de neutrons thermique decroit rapidement dans le tissue (couche de demi-attenuation Approximately-Equal-To 8 cm), il faut que les doses incidentes a la suriace soient elev ees pour obtenir une dose profonde suffisante.

La compresión de estas señales permite disminuir el volumen de datos adquiridos, facilitando su manipulación. La epilepsia es una de las más comunes de esas enfermedades y las señales que registran este tipo de anomalía difieren algo de las señales electroencefalográficas comunes. En este trabajo se analiza el comportamiento de la compresión de señales que contienen episodios epilépticos, comparado con otras que no lo contienen. Se establecen un grupo de parámetros de calidad y de compresión para establecer la comparación. Como resultado se obtiene una mejor calidad y una mayor compresión cuando la señal contiene episodios epilépticos.

Full Text Available Resumen Este trabajo se ocupa de analizar una serie de cuestiones que se desprenden de los sucesos ocurridos en Ezeiza, el 20 de junio de 1973, en el contexto de la vigilia por el regreso a la Argentina de Juan Domingo Perón. En tal sentido, en primer lugar se pretenderá definir si la conceptualización “masacre”, semánticamente, mantiene un correlato con los eventos desarrollados durante esa jornada. En segundo lugar, se buscará analizar si es posible aseverar, que la izquierda peronista en su conjunto fue la víctima ingenua de una matanza perpetrada intencionalmente para desplazar a Cámpora y copar el poder. Por último, se tratará de examinar cómo el 20 de junio de 1973, se evidenciaron las contradicciones existentes entre la conducción de Montoneros y Perón, y cómo estas diferencias acabaron cristalizándose en los incidentes ocurridos. Abstract This work focuses on analyzing a series of issues that took place during June 20th 1973 in Ezeiza in the context of the eve for the return of Juan Domingo Perón to Argentina. In first place, it will be attempted to define if the concept of “Massacre”, in a semantic way, keeps a correlation with the events that developed during that day. Secondly, an analysis will be made to see if it is possible to asseverate that the “Peronist left-wing movement” was an innocent victim of a bloodbath made intentionally to displace Cámpora and take the power. Finally, we will examine how on June 20th 1973 the contradictions between Montoneros and Perón became evident and how these differences, in the end, were reflected in the incidents.

Full Text Available Fundamento. Las vacunas son medicamentos termolábiles y para garantizar su inmunogenicidad y eficacia protectora, dentro de los programas de inmunización, es imprescindible mantener la cadena de frío. El elemento fundamental en esta cadena es el personal responsable de las vacunas, que debe conocer las características de estabilidad de cada preparado con el fin de evitar errores durante su manipulación. El objetivo de este trabajo fue conocer cómo se realiza el mantenimiento de la cadena del frío en equipos de atención primaria de un área sanitaria de la Comunidad Autónoma de Madrid, así como establecer el grado de información que poseen los responsables de las vacunas con respecto a la termoestabilidad de las mismas. Métodos. Se ha realizado un estudio transversal en 46 puntos de vacunación en atención primaria. La recogida de los datos se realizó mediante entrevista personal por un único investigador. Resultados. La tasa de participación fue del 93,5% (43/46. En todos los casos existía termómetro de máxima y mínima y registro mensual de la temperatura. Se observó una temperatura inadecuada en tres ocasiones (6,97%. El porcentaje de profesionales que conocía el efecto que la congelación producía sobre las vacunas fue muy diverso: 53.5%, 51.2%, 44.2% y 53.5% para difteria-tétanos-pertussis (DTP, hepatitis B (VHB, polio oral (VPO y rubéola-sarampión-paperas (RSP respectivamente. Y sólo el 32% conocía el test de agitación. Conclusión. La formación de los profesionales sobre el efecto que las altas temperaturas ocasionan en las vacunas era correcta, pero es necesario reforzar su formación sobre la inestabilidad que presentan los preparados adsorbidos cuando se someten a congelación.

Dual-bath electrodeposition of n-type Bi–Te/Bi–Se multilayer thin films
Energy Technology Data Exchange (ETDEWEB)
Matsuoka, Ken; Okuhata, Mitsuaki; Takashiri, Masayuki, E-mail: takashiri@tokai-u.jp
2015-11-15
N-type Bi–Te/Bi–Se multilayer thin films were prepared by dual-bath electrodeposition. We varied the number of layers from 2 to 10 while the total film thickness was maintained at approximately 1 μm. All the multilayer films displayed the X-ray diffraction peaks normally observed from individual Bi{sub 2}Te{sub 3} and Bi{sub 2}Se{sub 3} crystal structures, indicating that both phases coexist in the multilayer. The cross-section of the 10-layer Bi–Te/Bi–Se film was composed of stacked layers with nano-sized grains but the boundaries between the layers were not planar. The Seebeck coefficient was almost constant throughout the entire range of our experiment, but the electrical conductivity of the multilayer thin films increased significantly as the number of layers was increased. This may be because the electron mobility increases as the thickness of each layer is decreased. As a result of the increased electrical conductivity, the power factor also increased with the number of layers. The maximum power factor was 1.44 μW/(cm K{sup 2}) for the 10-layer Bi–Te/Bi–Se film, this was approximately 3 times higher than that of the 2-layer sample. - Highlights: • N-type Bi–Te/Bi–Se multilayer thin films were deposited by electrodeposition. • We employed a dual-bath electrodeposition process for preparing the multilayers. • The Bi–Te/Bi–Se film was composed of stacked layers with nano-sized grains. • The electrical conductivity increased as the number of layers was increased. • The power factor improved by 3 times as the number of layers was increased.

Double-labelling liver scintigraphy was used to specify the nature of lacunar images visible on conventional liver scintigraphs. The method is based on the successive injection of two radio-elements of different energies: 99m technetium in colloidal sulphide form than 75 Se-L-selenomethionine. Each injection is followed by a scintigraphic recording with a scintillation camera and a data processing system allows the 99m technetium image to be subtracted from that obtained by 75 Se-L-selenomethionine. Electronic subtraction operations have the advantage that the tumour image is visible not only in cases of 75 Se-L-selenomethionine hyperfixation but also when an isofixation or moderate hypofixation exists in the pathological or lacunar zone. This double-labelling scintigraphic examination is extremely valuable diagnostically in distinguishing between a primary and a secondary liver cancer: 58 hepatocarcinomas and 29 liver metastases were in this way explored, in addition to 10 mixed observations of benign liver tumours and extrinsic liver compressions. Primary and secondary liver cancers may be characterised by a 75 Se-L-selenomethionine uptake index in the lacunar zones and can hence be distinguished more objectively [fr

Full Text Available La gestión de sistemas de inventarios constituye una de las funciones más complejas de las organizaciones, ya que implica mantener existencias para protegerse contra incertidumbres al menor costo. Esta complejidad se hace más aguda en economías emergentes, donde factores internos propios de las organizaciones y externos de tipo económicos, políticos y sociales del entorno afectan esta gestión y las decisiones que se toman con base en la aplicación de modelos cuantitativos y políticas de administración desarrolladas para tal fin. De allí, surge la necesidad de analizar la gestión de inventarios desde el contexto en que se desenvuelven las empresas de estos países. En este artículo se presenta una revisión acerca de los factores que inciden sobre la gestión de los sistemas de inventario, tomando en cuenta aspectos operativos y de tipo estratégicos que son relevantes para su adecuada administración. Para tal fin, se hizo la revisión y contrastación de artículos en el marco de esta temática desarrollados por Vidal y otros (2004, Ortiz (2004, Lópes y Gómez (2013, Ponsot (2008 y Vries (2007 principalmente. Se encontró que son diversos los factores que tienen su incidencia en la adecuada gestión de los sistemas de inventarios en las organizaciones enmarcadas en entornos subdesarrollados como el caso de Venezuela.

Full Text Available Physalis peruviana L. (uchuva), de la familia Solanaceae, es una de las frutas más importantes en términos de exportaciones para Colombia debido a sus propiedades nutricionales y medicinales. En nuestro país la caracterización morfológica y evaluación de los bancos de germoplasma ha comenzado a implementarse. El objetivo de la presente investigación es la caracterización morfológica mediante descriptores discriminantes de 29 Introducciones de uchuva representativas de la colección de trabajo de la Universidad Nacional de Colombia sede Palmira. El trabajo se realizó en la Reserva Natural "La Albecia", vereda Regaderos, corregimiento de Aují, Municipio de El Cerrito - Valle del Cauca, a una altura de 1945 msnm, temperatura de 18-20°C, humedad relativa 70-80% y precipitación anual de 900-1200 mm. El ensayo se desarrolló en tres fases. En la primera se escogieron 29 introducciones representativas de la colección de trabajo de uchuva (CTU). En la segunda se estableció el ensayo bajo un diseño experimental de bloques completos al azar (BCA) y en la última fase se recopiló la información mediante descriptores cuantitativos y cualitativos previamente seleccionados. Se obtuvo un dendrograma a partir del análisis de conglomerado de varianza mínima de Ward, que determinó cinco grupos para las variables cualitativas. El tercer grupo explica el mayor grado de similitud entre las 29 introducciones evaluadas, con un porcentaje del 27.58. La mayor variabilidad estuvo relacionada con los caracteres del fruto: peso con y sin cáliz, grados Brix y diámetros polares y ecuatoriales.Physalis peruviana L.

La desaceleración económica colombiana: se cosecha lo que se siembra
Directory of Open Access Journals (Sweden)
Carlos Humberto Ortiz
2009-12-01
Full Text Available La desaceleración económica que experimenta Colombia desde 1980 se explica por el estancamiento estructural de la economía y por la escalada de violencia relacionada con la expansión del narcotráfico. Los datos disponibles no rechazan esta hipótesis. El artículo plantea que la desindustrialización y el narcotráfico se forjaron en el mismo crisol: un modelo de desarrollo que ha integrado progresivamente la economía nacional a los mercados mundiales al tiempo que ha renunciado, también progresivamente, a la opción industrialista. Además, argumenta que la explosión del narcotráfico obedece a la profundización de la guerra contra las drogas en un contexto de demanda mundial creciente e inelástica.

Influencia de la fase sigma en la laminación en frío de los aceros inoxidables dúplex
Directory of Open Access Journals (Sweden)
Fargas, G.
2004-04-01
Full Text Available One of the steps in the industrial rolling process of duplex stainless steels is the annealing heat treatment after hot rolling. If this annealing is performed in a temperature range that favours the precipitation of intermetallic phases, the mechanical properties can be modified considerably. The formation of these precipitates has a detrimental effect on the DSS ductility and toughness, so it will be a drawback for further cold rolling. In the present investigation, the effect of the sigma phase during cold rolling of a duplex stainless steel type EN 1.4462 has been studied. To simulate this process, compression tests up to a thickness reduction similar to that performed at industrial level have been done. The testing samples were studied by optical microscopy, SEM (scanning electronic microscopy and TEM (transmission electronic microscopy. Afterwards, some of the annealing conditions were selected in order to carry out cold rolling, using a laboratory scale machine, with the aim to observe if they offered a similar behaviour as that experienced in the compression tests. The results show that only the annealing condition at 975ºC during 10 minutes allows to produce sheets without rolling defects.
Una de las etapas en el proceso de fabricación industrial de los aceros inoxidables dúplex laminados es el tratamiento térmico de recocido posterior a la laminación en caliente. Si dicho recocido se efectúa en un rango de temperaturas que favorezca la formación de fases intermetálicas, las propiedades mecánicas del material pueden modificarse notablemente. La presencia en la microestructura bifásica de dichos precipitados provoca efectos muy perjudiciales sobre la ductilidad y la tenacidad del material, pudiendo llegar a hacer inviable la posterior etapa de laminación en frío. En el presente trabajo se ha estudiado el efecto sobre el proceso de laminación en frío de la presencia de fase sigma en un acero dúplex tipo E.N. 1 -

Los estados frágiles y el retorno de la administración nativa.

Mark DUFFIELD
2008-06-01
Full Text Available Durante los últimos años, un número de ideas relacionadas con el trabajo en “entornos difíciles”, o que implican países descritos como “malos actores” o “estados frágiles” han entrado en el discurso político. Tratan de describir el reto del desarrollo en una época de inestabilidad global y de extendido fallo estatal. Estas ideas son similares en contenido y aquí nos referimos a ellas como el estado frágil, o el discurso sobre el estado frágil. El pensamiento de los gobiernos donantes sobre la reconstrucción de los estados frágiles se entiende como la punta de lanza de la política actual. De cualquier forma, además de explorar éste discurso, éste trabajo se basa en las suposiciones y disposiciones desarrolladas dentro de la cobertura del imperialismo liberal, en concreto, la práctica colonial del gobierno indirecto o administración nativa. En vez de ser esencialmente nuevo, el discurso sobre el estado frágil es más bien una reinscripción contemporánea de enfoques anteriores sobre el problema del espacio no gobernado. Dado el fallo histórico de semejantes tecnologías para revertir el rechazo al tutelaje occidental, en una época de guerra indefinida y de creciente insurgencia global, es tan urgente como relevante un examen crítico de esta arqueología. Over the last several years, a number of ideas relating to working in “difficult environments”, or engaging countries described as “poor performers” or “fragile states” have entered policy discourse. They attempt to describe the challenge for development at a time of global instability and the widespread occurrence of state failure. In content, these ideas are similar and are referred to here as the fragile state, or fragile state discourse. Donor government thinking on reconstructing fragile states is regarded as the cutting-edge of current policy. Besides exploring this discourse however, this paper draws out its reliance on assumptions and

replenishment with unused oil.La finalidad del estudio fue obtener información sobre el uso de freidoras domésticas, tipo de aceite utilizado para freír, alimentos que se fríen y número de frituras tras el que se elimina el aceite. Para ello se realizó una encuesta preliminar en 50 personas pertenecientes a la Universidad Complutense de Madrid para conocer qué tipo de aceite y qué alimentos se emplean en fritura doméstica. Ninguna de ellas usaba un aceite diferente del de oliva o girasol. Con estos datos se realizó otra encuesta entre 250 universitarios en cuyos hogares se empleaba freidora acerca del aceite empleado, los alimentos que se fríen más habitualmente y el número de fritura tras el que se desecha el aceite usado. Los resultados señalan que en los hogares de estos universitarios, el aceite más utilizado para freír es el de oliva. La mayoría de ellos usa el aceite de 11 a 20 veces y aproximadamente la mitad de los encuestados fríen sólo un tipo de alimento en el mismo aceite. Los alimentos que se fríen con más frecuencia en sartén eran las patatas, las patatas prefritas congeladas y el pescado, observándose una preferencia al uso de la sartén respecto al de la freidora para los alimentos frescos, mientras que no había preferencias respecto a los precocinados. Teniendo en cuenta los resultados de la segunda encuesta se realizaron un total de 20 frituras de alimentos congelados en freidoras domésticas en aceite de oliva virgen extra, girasol y girasol con alto contenido en ácido oleico. Las croquetas fritas se valoraron mediante cata, realizándose pruebas triangulares de identificación y de puntuación con la finalidad de estudiar el efecto del aceite empleado en su fritura. También se evaluó la calidad organoléptica global de las croquetas fritas en función de la modalidad de fritura (con o sin adición de aceite sin usar y del tipo de aceite. La aceptación de las croquetas fue bastante buena, con una puntuación de 6,8 sobre una escala

Renal cell carcinoma: incidental detection and pathological staging.
Siow, W Y; Yip, S K; Ng, L G; Tan, P H; Cheng, W S; Foo, K T
2000-10-01
In developed countries, there has been increased incidental detection of renal cell carcinoma (RCC). The incidence, pathological stage and survival of incidentally detected carcinoma in a developing country in Asia where, from 1990 to 1998, 165 renal cell carcinomas were identified. The clinical presentation, diagnostic-imaging modality employed, pathological staging and patient survival was reviewed. Incidental renal cancers included those that were diagnosed through health screening or detected incidentally through imaging studies for other conditions. The survival between these incidentally detected lesions and their symptomatic counterparts (suspected group) was compared. Sixty-four patients (39%) had their tumours detected incidentally, including 39 who were entirely asymptomatic and 25 who presented with non-specific symptoms, not initially suggestive of RCC. For the entire group, computed tomography provided the definitive diagnosis in 81% of cases. The incidental detection group had significantly smaller size of tumour (5.9 cm c.f. 7.6 cm), lower stage and lower histological grading. In particular, 78% of patients with incidental RCC had stage I or II diseases (TNM stage classification), compared with 57% of patients with suspected tumour (p c.f. 66% at last follow up; p < 0.05; log-rank test) over a mean follow up period of 33 months (range 1-91). Regression analysis showed that stage of disease was the only independent variable predictive of clinical outcome. In conclusion, that significant numbers of RCC were detected incidentally. These tumours were of a lower clinical pathological stage and had a better prognosis.

Concentrations of trace elements (V, Cr, Mn, Fe, Co, Cu, Zn, Ga, As, Se, Rb, Sr, Mo, Ag, Cd, Sb, Cs, Ba, T-Hg, Org-Hg, Tl and Pb) were determined in liver samples of estuarine dolphin (Sotalia guianensis; n=20), Franciscana dolphin (Pontoporia blainvillei; n=23), Atlantic spotted dolphin (Stenella frontalis; n=2), common dolphin (Delphinus capensis; n=1) and striped dolphin (Stenella coeruleoalba; n=1) incidentally caught along the coast of Sao Paulo State and Parana State, Brazil, from 1997 to 1999. The hepatic concentrations of trace elements in the Brazilian cetaceans were comparable to the data available in literature on marine mammals from Northern Hemisphere. Concentrations of V, Se, Mo, Cd, T-Hg and Org-Hg increased with increasing age in liver of both estuarine and Franciscana dolphins. Very high concentrations of Cu (range, 262-1970 {mu}g/g dry wt.) and Zn (range, 242-369 {mu}g/g dry wt.) were observed in liver of sucklings of estuarine dolphin. Hepatic concentrations of V, Se, T-Hg, Org-Hg and Pb were significantly higher in estuarine dolphin, whereas Franciscana dolphin showed higher concentrations of Mn, Co, As and Rb. Ratio of Org-Hg to T-Hg in liver was significantly higher in Franciscana dolphin than estuarine dolphin, suggesting that demethylation ability of methyl Hg might be lower in liver of Franciscana than estuarine dolphins. High hepatic concentrations of Ag were found in some specimens of Franciscana dolphin (maximum, 20 {mu}g/g dry wt.), and 17% of Franciscana showed higher concentrations of Ag than Hg. These samples with high Ag concentration also exhibited elevated hepatic Se concentration, implying that Ag might be detoxified by Se in the liver. Higher correlation coefficient between (Hg + 0.5 Ag) and Se than between Hg and Se and the large distribution of Ag in non-soluble fraction in nuclear and mitochondrial fraction of the liver also suggests that Ag might be detoxified by Se via formation of Ag{sub 2}Se in the liver of Franciscana

Voigt, P.; Fahnert, J.; Kahn, T.; Surov, A.; Schramm, D.; Bach, A.G.
2017-01-01
Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance.

The extent and intensity of 18F FDG uptake in prostate cancer patients are known to be variable, and the clinical significance of focal 18F fluorodeoxyglucose ( 18F FDG) uptake that is incidentally found on positron emission tomography (PET) has not been established. We investigated the clinical significance of incidental focal prostate uptake of 18F FDG on PET/computed tomography (CT) and analyzed differential findings on PET/CT Between malignant and benign uptake. A total of 14,854 whole body 18F FDG PET/CT scans (4,806 that were conducted during cancer screening and 10,048 that were conducted to evaluate suspected of alleged cancer outside of the prostate) were retrospectively reviewed to determine the presence, location, multiplicity reviewed to determine the presence, location, multiplicity and maximum standardized uptake value (SUVmax) of focal prostate uptake and combined calcification. The final diagnosis determined by serum prostate specific antigen (PSA) level and biopsy was compared with PET findings. Incidental focal prostate uptake was observed in 148 of 14,854 scans (1.0%). Sixty seven of these 148 subjects who had diagnostic confirmation were selected for further analysis. Prostate cancer was diagnosed in nine of 67 subjects (13.4%). The remaining 58 subjects had no malignancy in the prostate based on normal serum PSA level (n=53), or elevated serum PSA level with a negative biopsy result (n=5). While 84.6% (11/13) of malignant uptake was peripherally located in the prostate glands, 60.2% (50/83) of benign uptake was centrally located (p 18F FDG uptake un the prostate is not common, the incidence of cancer with focal uptake is not low. Therefore, these findings deserve further evaluation. The location of the focal prostate uptake may help with the selection of high risk prostate cancer patients.

Aim: Magnetic resonance imaging (MRI) is a powerful clinical tool used increasingly in the research setting. We aimed to assess the prevalence of incidental findings in a sequential cohort of healthy volunteers undergoing whole-body MRI as part of a normal control database for imaging research studies. Materials and methods: 148 healthy volunteers (median age 36 years, range 21-69 years; 63.5% males, 36.5% females) were enrolled into a prospective observational study at a single hospital-based MRI research unit in London, UK. Individuals with a clinical illness, treated or under investigation were excluded from the study. Results: 43 (29.1%) scans were abnormal with a total of 49 abnormalities detected. Of these, 20 abnormalities in 19 patients (12.8%) were of clinical significance. The prevalence of incidental findings increased significantly with both increasing age and body mass index (BMI). Obese subjects had a fivefold greater risk of having an incidental abnormality on MRI (OR 5.4, CI 2.1-14.0). Conclusions: This study showed that more than one quarter of healthy volunteers have MR-demonstrable abnormalities. There was an increased risk of such findings in obese patients. This has ethical and financial implications for future imaging research, particularly with respect to informed consent and follow-up of those with abnormalities detected during the course of imaging studies.

Incidentes y riesgos de involución en la Corte Penal Internacional
Directory of Open Access Journals (Sweden)
Carlos Cerda Dueñas
2017-08-01
Full Text Available En octubre del 2016, tres países parte del Estatuto de Roma informaron la denuncia de este instrumento y, por lo tanto, su retiro de la Corte Penal Internacional. Los denunciantes, todos africanos, fundamentaron su decisión en una supuesta parcialidad de la corte, en función de que, a excepción de uno, los casos resueltos y en investigación corresponden a países de dicho continente. En tal sentido, este artículo tiene como objetivo central analizar las causas oficialmente esgrimidas por estos tres Estados para retirarse, cotejadas con los hechos que, se considera, motivaron su decisión, así como examinar los cuestionamientos y hostilidades que la corte ha recibido de otros miembros de la comunidad internacional. Se concluye que su eventual salida, si bien conlleva un significativo golpe a su credibilidad, le genera contratiempos en su consolidación y también riesgos de involución, no pone en riesgo la viabilidad de la corte, y que el mayor desafío se encuentra en los ataques infligidos por otros países que no son parte de la misma. El método de este artículo plantea una revisión somera a algunos aspectos del trabajo jurisdiccional de la corte en sus catorce años de existencia, que han generado los blancos más recurrentes de sus críticas.

The photoluminescence (PL) and electroluminescence (EL) properties of OLEDs based on poly( N-vinylcarbazole)(PVK) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) have been studied. A new emission at 595 nm has been observed in EL spectra but not in PL spectra of the devices. We suggest the new emission originates from the electroplex occuring at PVK-BCP interface. White emission via electroplex has been obtained in all the OLEDs. CIE coordinates of device ITO/PEDOT:PSS/PVK/BCP/Alq 3/LiF/Al is (0.31, 0.33) at 18 V. Alq 3 layer plays an important role in tuning the recombination zone and enhancing the electroplex emission.

Thin films of (CdSe)90(In2O3)10, (CdSe)90(SnO2)10 and (CdSe)90(ZnO)10 have been grown on glass substrates by the electron beam evaporation technique. It has been found that undoped and Sn or In doped CdSe films have two direct transitions corresponding to the energy gaps Eg and Eg+Δ due to spin-orbit splitting of the valence band. The electrical resistivity for n-doped CdSe thin films as a function of light exposure time has been studied. The influence of doping on the structural, optical and electrical characteristics of In doped CdSe films has been investigated in detail. The lattice parameters, grain size and dislocation were determined from x-ray diffraction patterns. The optical transmittance and band gap of these films were determined using a double beam spectrophotometer. The DC conductivity of the films was measured in vacuum using a two-probe technique.

Catabolism of neurotensin by neural (neuroblastoma clone N1E115) and extraneural (HT29) cell lines
International Nuclear Information System (INIS)
Checler, F.; Amar, S.; Kitabgi, P.; Vincent, J.P.
1986-01-01
The mechanisms by which neurotensin (NT) was inactivated by differentiated neuroblastoma and HT29 cells were characterized. In both cell lines, the sites of primary cleavages of NT were Pro7-Arg8, Arg8-Arg9 and Pro10-Tyr11 bonds. The cleavage at the Pro7-Arg8 bond was totally inhibited by N-benzyloxycarbonyl-Prolyl-Prolinal and therefore resulted from the action of proline endopeptidase. This peptidase also contributed in a major way to the cleavage at the Pro10-Tyr11 bond. However the latter breakdown was partly due to an NT-degrading neutral metallopeptidase. Finally, we demonstrated the involvement of a recently purified rat brain soluble metalloendopeptidase at the Arg8-Arg9 site by the use of its specific inhibitor N-[1(R,S)-carboxy-2-Phenylethyl]-alanylalanylphenylalanine-p-amino benzoate. The secondary processing of NT degradation products revealed differences between HT29 and N1E115 cells. Angiotensin converting enzyme was shown to degrade NT1-10 and NT1-7 in N1E115 cells but was not detected in HT29 cells. A post-proline dipeptidyl aminopeptidase activity converted NT9-13 into NT11-13 in HT29 cells but not in N1E115 cells. Finally, bestatin-sensitive aminopeptidases rapidly broke down NT11-13 to Tyr in both cell lines. Models for the inactivation of NT in HT29 and N1E115 cells are proposed and compared to that previously described for purified rat brain synaptic membranes

Incidental Vocabulary Learning in Second Language Acquisition: A Literature Review
Directory of Open Access Journals (Sweden)
Falcon Dario Restrepo Ramos
2015-01-01
Full Text Available This literature review aims to analyze previous studies that address the incidental learning of vocabulary in second language acquisition. The articles included in this literature review look into the understanding of vocabulary learning through incidental means, the relationship of reading and incidental vocabulary learning, and the strategies and tasks that promote the incidental learning of vocabulary. The findings show that L2 learners develop much of their vocabulary by incidental means through exposure to words in informative contexts. Moreover, this exposure is promoted by reading, and enhanced through multimodal glosses. Further research may focus on listening for higher lexical retention rates, the circumstances that allow incidental learning of multi-word phrases and collocations, and the use of technology-based methods for incidental vocabulary acquisition.

Incidental diagnosis of tumor thrombosis on FDG PET/CT imaging.
Erhamamci, S; Reyhan, M; Nursal, G N; Torun, N; Yapar, A F
2015-01-01
Clinical data are presented on patients with tumor thrombosis (TT) incidentally detected on FDG PET/CT imaging, as well as determining its prevalence and metabolic characteristics. Out of 12,500 consecutive PET/CT examinations of patients with malignancy, the PET/CT images of 15 patients with TT as an incidental finding were retrospectively investigated. A visual and semiquantitative analyses was performed on the PET/CT scans. An evaluation was made of the pattern of FDG uptake in the involved vessel as linear or focal via visual analyses. For the semiquantitative analyses, the metabolic activity was measured using SUVmax by drawing the region of interest at the site of the thrombosis and tumor (if any). The prevalence of occult TT was 0.12%. A total of 15 patients had various malignancies including renal (1 patient), liver (4), pancreas (2), stomach (1), colon (1), non-Hodgkin lymphoma (1), leiomyosarcoma (1), endometrial (1), ovarian (1), malign melanoma (1) and parotid (1). Nineteen vessels with TT were identified in 15 patients; three patients had more than one vessel. Various vessels were affected; the most common was the inferior vena cava (n=7) followed by the portal (n=5), renal (n=3), splenic (n=1), jugular (n=1), common iliac (n=1) and ovarian vein (n=1). The FDG uptake pattern was linear in 12 and focal in 3 patients. The mean SUVmax values in the TT and primary tumors were 8.40±4.56 and 13.77±6.80, respectively. Occult TT from various malignancies and locations was found incidentally in 0.12% of patients. Interesting cases with malign melanoma and parotid carcinoma and with TT in ovarian vein were first described by FDG PET/CT. Based on the linear FDG uptake pattern and high SUVmax value, PET/CT may accurately detect occult TT, help with the assessment of treatment response, contribute to correct tumor staging, and provide additional information on the survival rates of oncology patients.

FE se calculó mediante el método triangular según la relación entre la fracción de la cobertura de suelo (Fr y la temperatura de superficie (Ts. Ambas variables fueron correlacionadas para cada tipo de cobertura por ecorregión. Fr y Ts están inversamente asociadas, y diferentes coberturas por ecorregiones mostraron cambios en la pendiente de la recta entre ambas variables debido a cambios en el porcentaje y el tipo de cobertura, en los gradientes pluviométricos y en la estructura de la vegetación. Los valores medios de Fr y FE por ecorregiones y tipo de cobertura fueron procesados mediante el análisis de la varianza y por comparaciones múltiples de Fisher. Existen diferencias estadísticas significativas en las variables Fr y FE según el tipo de cobertura, y la ecorregión y la relación entre Fr y FE no es lineal. Finalmente, se generó un mapa con la distribución espacial de la FE.

Many earth-abundant transition metal dichalcogenides (TMDs) have been employed as catalysts for H2 evolution reaction (HER); however, their impactful integration onto photocathodes for photoelectrochemical (PEC) HER is less developed. In this study, we directly sputtered a MoSe2 catalyst onto an n+p-Si photocathode for efficient and stable PEC-HER. An onset potential of 0.4 V vs. RHE, a saturated photocurrent of 29.3 mA/cm2, a fill factor of 0.32, and an energy conversion efficiency of 3.8% were obtained under 100 mA/cm2 Xe lamp illumination. Such superior PEC properties were ascribed to the nearly vertically standing two dimensional MoSe2 rough surface layer and the sharp interface between Si and MoSe2 with small charge transfer resistance. The balance between the reflectivity of the electrode surface and the absorptivity of MoSe2 was also discussed. In addition, the MoSe2 layer can protect the n+p-Si photocathode with a 120 h stability due to its initial growth on Si with high flatness and compactness. This study provides a path to the effective and scalable growth of TMDs onto the Si photocathode aiming for high efficiency and stability.

2014-01-01
Full Text Available Objective. This study aimed to evaluate the CT features of incidentally detected DTD in the patients who underwent thyroidectomy and to assess the diagnostic accuracy of CT diagnosis. Methods. We enrolled 209 consecutive patients who received preoperative neck CT and subsequent thyroid surgery. Neck CT in each case was retrospectively investigated by a single radiologist. We evaluated the diagnostic accuracy of individual CT features and the cut-off CT criteria for detecting DTD by comparing the CT features with histopathological results. Results. Histopathological examination of the 209 cases revealed normal thyroid (n=157, Hashimoto thyroiditis (n=17, non-Hashimoto lymphocytic thyroiditis (n=34, and diffuse hyperplasia (n=1. The CT features suggestive of DTD included low attenuation, inhomogeneous attenuation, increased glandular size, lobulated margin, and inhomogeneous enhancement. ROC curve analysis revealed that CT diagnosis of DTD based on the CT classification of “3 or more” abnormal CT features was superior. When the “3 or more” CT classification was selected, the sensitivity, specificity, positive and negative predictive values, and accuracy of CT diagnosis for DTD were 55.8%, 95.5%, 80.6%, 86.7%, and 85.6%, respectively. Conclusion. Neck CT may be helpful for the detection of incidental DTD.

From these arguments on, the relationship between literature and religion becomes closer, allowing us to understand both literature and religion as forms of symbolic production: poetic and normative interpretations of life in the world. To understand it in those terms, key concepts of literary hermeneutics developed by Paul Ricoeur are evoked. These terms are used as categories of analysis to facilitate a hermeneutic understanding of the actual event of the literary text.

Highlights: • Mo/MoN{sub x}/Mo multilayer was investigated as a back contact for CIGS solar cell. • The MoN{sub x} protected the underlying Mo layer during high temperature selenization. • The formation of MoSe{sub 2} layer was precisely controlled. • The diffusion barrier performance of MoN{sub x} against Se was evaluated using TEM analysis. - Abstract: This study investigated the interfacial reactions and electrical properties of a Mo single layer and Mo/MoN{sub x}/Mo multilayer during high temperature selenization annealing. The Mo single layer was converted easily to MoSe{sub 2}, which was 7 times thicker than the Mo layer consumed ∼900 nm, by selenization at 460 °C for 10 min and the sheet resistance increased 8 fold compared to that of the as-deposited Mo film. On the other hand, in the Mo/MoN{sub x}/Mo structure, transmission electron microscopy (TEM) showed that the MoSe{sub 2} transformation was localized only in the top Mo layer and the bottom Mo layer was completely unaffected, even after selenization at 560 °C. The sheet resistance of the multilayer was relatively unchanged by selenization. This suggests that the MoN{sub x} layer performed well as a diffusion barrier against Se and the thickness of MoSe{sub 2} can be controlled precisely by adjusting the top Mo layer thickness. Furthermore, TEM and energy dispersive spectroscopy analysis showed that the selenized multilayer consisted of MoSe{sub 2}/Mo/MoN{sub x}/Mo, in which the top Mo layer of 60 nm was not fully converted to MoSe{sub 2} and 20 nm was left unreacted. The residual Mo interlayer located at the interface of MoSe{sub 2} and MoN{sub x} is believed to be beneficial for the ohmic contact of the selenized multilayer.

Relative Preference and Localized Food Affect Predator Space Use and Consumption of Incidental Prey.
Directory of Open Access Journals (Sweden)
Tyler E Schartel
Full Text Available Abundant, localized foods can concentrate predators and their foraging efforts, thus altering both the spatial distribution of predation risk and predator preferences for prey that are encountered incidentally. However, few investigations have quantified the spatial scale over which localized foods affect predator foraging behavior and consumption of incidental prey. In spring 2010, we experimentally tested how point-source foods altered how generalist predators (white-footed mice, Peromyscus leucopus utilized space and depredated two incidental prey items: almonds (Prunus dulcis; highly profitable and maple seeds (Acer saccharum; less profitable. We estimated mouse population densities with trapping webs, quantified mouse consumption rates of these incidental prey items, and measured local mouse activity with track plates. We predicted that 1 mouse activity would be elevated near full feeders, but depressed at intermediate distances from the feeder, 2 consumption of both incidental prey would be high near feeders providing less-preferred food and, 3 consumption of incidental prey would be contingent on predator preference for prey relative to feeders providing more-preferred food. Mouse densities increased significantly from pre- to post-experiment. Mean mouse activity was unexpectedly greatest in control treatments, particularly <15 m from the control (empty feeder. Feeders with highly preferred food (sunflower seeds created localized refuges for incidental prey at intermediate distances (15 to 25m from the feeder. Feeders with less-preferred food (corn generated localized high risk for highly preferred almonds <10 m of the feeder. Our findings highlight the contingent but predictable effects of locally abundant food on risk experienced by incidental prey, which can be positive or negative depending on both spatial proximity and relative preference.

The contribution of electron capture to weak-decay rates has been neglected in model calculations of Type I X-ray bursts so far. Nucleosynthesis in these astrophysical events eventually proceeds through the rp-process near the proton drip-line. In particular, several N=Z nuclei such as $^{64}$Ge and $^{68}$Se act as waiting points in the nuclear flow due to the low S${_P}$ values of their Z+1 neighbours. Recent theoretical calculations have shown that, in these high density ($\\thicksim10^{6}$ g/cm$^3$) and high temperature (1 - 2 GK) scenarios, continuum electron capture rates might play an important role, in particular for species at and around these waiting point nuclei. This proposal is aimed at the study of the $\\beta^{+}$/EC-decay of the waiting point nuclei $^{64}$Ge, $^{68}$Se and their N=Z+2 second neighbours $^{66}$Ge and $^{70}$Se with the Total Absorption Spectroscopy method. This will allow for a detailed analysis of their contribution to the EC-decay rates in X-Ray burst explosions. The proposed ...

The purpose of this study is to evaluate clinico-radiological findings and to estimate frequency of incidental meningiomas detected by brain check-up (BC). A total of 12,258 healthy adults (8,515 men and 3,743 women) had BC, using physical check-up, brain magnetic resonance imaging (MRI) and MR angiography. Mean age (SD) was 52.6 (11.4) years, 52.7 (11.2) in men and 52.5 (11.8) in women. Duration of this study was between April 2004 and March 2007. BC subjects were divided into the first BC and the repeated BC group. The number of the first BC subjects was 5,056 (3,284 men and 1,772 women). In the repeated group defined that they had the first BC before April 2004 in our center, there were 7,202 subjects (5,231 men and 1,971 women). Fifteen subjects (7 men and 8 women) were diagnosed as meningiomas. Fourteen cases were detected by the first BC and one case by the repeated BC. The percentage of incidental meningiomas in the first BC group was calculated as 0.28, 0.18 in men and 0.45 in women. The sex ratio of women/men was 2.5. The mean age of those cases was 55.2 (10.1), 54.6 (12.9) in men and 55.8 (7.7) in women. Incidental rate of meningioma in the repeated BC group was calculated as 0.01% and 0.02% in men. No subjects had meningioma at age ≤30 years. Asymptomatic meningiomas were seen in 14 cases (93.3%) and they expected BC to ascertain healthy and normal brain by themselves. The size of tumors was ranged 10 to 46 mm and mean (SD) was 21.3 (10.2) mm. The locations of meningiomas were variable. Three cases had surgical removal. Twelve cases were under investigation on MRI. In middle-aged working subjects, incidental rates of asymptomatic meningiomas detected by BC are not uncommon in Japan. We should pay more attention to incidental meningioma when brain MRI is performed in 40-60 years women. (author)

Incidental emotions influence risk preference and outcome evaluation.
Zhao, Ding; Gu, Ruolei; Tang, Ping; Yang, Qiwei; Luo, Yue-Jia
2016-10-01
Incidental emotions, which are irrelevant to the current decision, play a significant role in the decision-making process. In this study, to investigate the influence of incidental emotions on behavioral, psychological, and electrophysiological responses in the process of decision making, participants were required to perform a monetary gambling task. During the selection stage, an emotional picture, which was chosen from the Chinese Affective Picture System and fell into one of three categories: negative, neutral, and positive, was presented between two alternatives (small/large amount of bet). The pictures were provided to induce incidental emotions. ERPs and self-rating emotional experiences to outcome feedback were recorded during the task. Behavioral results showed that positive incidental emotions elicited risk preference, but emotional experiences to outcome feedback were not influenced by incidental emotions. The feedback-related negativity amplitudes were larger in the positive emotion condition than in the negative and neutral emotion conditions for small outcomes (including wins and losses), whereas there was no difference between the three conditions for large outcomes. In addition, the amplitudes of P3 were reduced overall in the negative emotion condition. We suggest that incidental emotions have modulated both the option assessment stage (manifested in behavioral choices) and the outcome evaluation stage (manifested in ERP amplitudes) of decision making unconsciously (indicated by unchanged subjective emotional experiences). The current findings have expanded our understanding of the role of incidental emotion in decision making. © 2016 Society for Psychophysiological Research.

Effects of Incidental Emotions on Moral Dilemma Judgments: An Analysis Using the CNI Model.
Gawronski, Bertram; Conway, Paul; Armstrong, Joel; Friesdorf, Rebecca; Hütter, Mandy
2018-02-01
Effects of incidental emotions on moral dilemma judgments have garnered interest because they demonstrate the context-dependent nature of moral decision-making. Six experiments (N = 727) investigated the effects of incidental happiness, sadness, and anger on responses in moral dilemmas that pit the consequences of a given action for the greater good (i.e., utilitarianism) against the consistency of that action with moral norms (i.e., deontology). Using the CNI model of moral decision-making, we further tested whether the three kinds of emotions shape moral dilemma judgments by influencing (a) sensitivity to consequences, (b) sensitivity to moral norms, or (c) general preference for inaction versus action regardless of consequences and moral norms (or some combination of the three). Incidental happiness reduced sensitivity to moral norms without affecting sensitivity to consequences or general preference for inaction versus action. Incidental sadness and incidental anger did not show any significant effects on moral dilemma judgments. The findings suggest a central role of moral norms in the contribution of emotional responses to moral dilemma judgments, requiring refinements of dominant theoretical accounts and supporting the value of formal modeling approaches in providing more nuanced insights into the determinants of moral dilemma judgments.

2007-01-01
Full Text Available En los últimos años existe un creciente interés en materia de investigación turística, en un sector dinámico y de comportamiento especialmente complejo. En este escenario resulta de especial dificultad el manejo de las series temporales disponibles. La extracción de señal relevante en las series así como la realización de predicciones del comportamiento futuro de las cifras turísticas, cobran una especial importancia. En este trabajo se pretende realizar una comparación entre los métodos tradicionales y bayesianos de extracción de señal, de forma que el análisis empírico se aplica a las series turísticas más representativas de todas las provincias de la comunidad autónoma de Castilla-La Mancha. Los trabajos más frecuentes en la materia han abordado un análisis de estas series temporales a nivel internacional, nacional o regional; por ello, al descender a un nivel de desagregación provincial, los datos muestran mayores fluctuaciones y patrones de comportamiento y, por consiguiente, su modelización y predicción a futuro se hace más compleja.

The aim of this work was to evaluate the effect of mechanical pressing on jussara oil yield, oxidative stability and carotenoid profile with or without heat application. Firstly, jussara pulp was centrifuged for juice extraction, and the resulting cake was dried until reaching 10% moisture content. Then, oil extraction was performed in an expeller press at 25 ºC (cold pressing) and at 50 ºC (hot pressing). The process performance was evaluated by the oil yield, and the crude jussara oil was characterized for fatty acid composition, acid value, carotenoid profile and oxidative stability. Jussara oil contained 74% unsaturated fatty acids, mainly oleic and linoleic acids (48% and 24%, respectively). The oil yield was almost twice as high for the hot process as compared to the cold one. Additionally, hot pressing resulted in 25% higher total carotenoid content as compared to cold pressing, with β-carotene as the most abundant one. Hot and cold pressing showed no difference in oil oxidative stability and fatty acid composition. [Spanish] El objetivo de este estudio fue evaluar el efecto del calor sobre el rendimiento del aceite, la estabilidad oxidativa y el perfil de carotenoides del aceite de Jussara extraído por prensado mecánico. En primer lugar, se centrifugó la pulpa de jussara para la extracción del zumo, y la torta resultante se secó para alcanzar el contenido de humedad de 10%. Posteriormente, la extracción del aceite se realizó en una prensa a 25 °C (prensado en frío) y a 50 °C (prensado en caliente). El desarrollo del proceso fue evaluado mediante el rendimiento de aceite y en bruto y éste se caracterizó mediante la composición en ácidos grasos, índice de acidez, perfil de carotenoides y la estabilidad oxidativa. El aceite de jussara presentó un 74% de ácidos grasos insaturados, principalmente ácidos oleico y linoleico (48% y 24%, respectivamente). El rendimiento del aceite para el proceso en caliente fue casi el doble, en comparación

Tissue distribution study in rats and adrenal uptake in humans were carried out with 6 methyl- 75 Se-selenomethyl-19-norcholest-5(10)-en-3β-ol ( 75 Se-Scintadren) and 6β-iodomethyl-19-norcholest-5(10)-en-3β-ol ( 131 I-Adosterol). At Day 7, concentration of 75 Se-Scintadren in the adrenals was 8.9% kg dose/gm, which is approximately 40% of 131 I-Adosterol and adrenal-to-liver concentration ratio was about 30% of 131 I-Adosterol in rats. From the rat data and sequential adrenal uptake measurement in humans, it is recommended to take human adrenal images at 5 days later after a dose administration. However there are several advantages of 75 Se-Scintadren versus 131 I-Adosterol. On the contrary to the rat data, adrenal uptake in humans was calculated about 0.20 - 0.41% dose, which is nearly as same as that, of 131 I-Adosterol. Furthermore, counting efficiency of 75 Se with a scinitillation camera is 2.3 times that of 131 I. The advantages are as follows: (1) Administered dose can be reduced one-fourth of 131 I-Adosterol. (2) Estimated absorbed doses of adrenals were 99.8 rads/mCi extrapolated from the rat data and 31.6 - 63.2 rads/mCi from the human data, which are significantly less than that of 131 I-Adosterol per administered dose. (3) No thyroid-blocking is required. (4) Shelf-life is longer than that of 131 I-Adosterol. (author)

The excitation function of the reaction {sup 232} Th(n, 5nγ){sup 228} Th from 29 to 42 MeV has been measured for the first time at the quasi-monoenergetic neutron beam of the UCL cyclotron CYCLONE employing the {sup 7}Li(p,n) source reaction. Taking advantage of the good energy resolution of the planar High-Purity Germanium (HPGe) detectors, prompt γ-ray spectroscopy was used to detect the γ-rays resulting from the decay of excited states of nuclei created by the (n,xn) reactions. The neutron beam was characterized by a combination of time of flight measurements carried out using a liquid scintillation detector and a {sup 238}U fission ionization chamber. Fluence measurements were performed using a proton recoil telescope. The results are compared with TALYS-1.4 code calculations. (orig.)

Incidental Learning of Gender Agreement in L2.
Denhovska, Nadiia; Serratrice, Ludovica
2017-10-01
Incidental learning of grammar has been an area of interest for many decades; nevertheless, existing research has primarily focused on artificial or semi-artificial languages. The present study examines the incidental acquisition of the grammar of a natural language by exposing adult speakers of an ungendered L1 (English) to the gender agreement patterns in Russian (a language that was novel to the learners). Both receptive and productive knowledge and the mediating role of working memory (WM) in learning were measured. Speakers of the ungendered language were able to successfully acquire receptive but not productive grammatical knowledge in a new language under incidental exposure. WM was engaged in production but not in a grammaticality judgment task in the incidental learning condition, indicating cognitive effort during knowledge retrieval.

Construcción de una genoteca de cDNA de fríjol (Phaseolus vulgaris L. para mapeo genético
Directory of Open Access Journals (Sweden)
Roca William M.
1995-06-01
Full Text Available
A small cDNA library from beans (Phaseolus vulgaris L. of about 1500 clones was constructed, to further saturate the bean RFLP linkage map. The primarily synthesized cDNAs were amplified by PCR using the adaptors as primers for amplification (Jepson et al., 1991. Inserts in the range of 500 bp were obtained. 93 clones were singled for further analysis. They showed a degree of repeatibility of around 61 %. Around 80% of the unique clones were single copy, and 20% were low copy sequences as expected from a cDNA library. Three pairs of parental bean lines were chosen for their agronomical traits, and evaluated for polymorphism, which was highest as revealed by digestion with EcoRV (77%, followed by DraI (73%, EcoRI (63% and HindIIl (60%. The highest polymorphism was observed between the pair DOR60 and APNI8, 71% for EcoRV and 57% for EcoRI, respectively. Two clones of the two groups with the most repeated clones were analyzed by slot blot hybridization against the other clones and ribosomal DNA, to understand the origin of the repetitions. Only one clone seemed to be of ribosomal origin, as confirmed by the patterns obtained by hybridization to bean genomic DNA digested with HaelIl, implying that the whole group to which it belonged was of ribosomal origin. It can be explained by the combined utilization of the PCR amplification methodology and the multipleprimers for the synthesis of the first cDNA strand.

Se utilizaron 960 pollos de una línea comercial distribuidos en tres tratamientos: Alimentados a libre voluntad (T1, Restricción alimenticia del día 10 a 17 de edad (T2, Ayunados los días 15 y 17 de edad (T3. Todos los tratamientos recibieron una dieta de iniciación (1-28 días y finalización (29-41 días, balanceadas según las recomendaciones del NRC (1995 y en forma de harina. La ganancia de peso durante el periodo de restricción (10-17 días fue inferior (P 0.05 y sólo a la edad de sacrificio (41 días se completó la respuesta "compensatoria" en el peso corporal de los tratamientos restringidos. I El consumo de los tratamientos restringidos fue inferior (P 0.05 entre tratamientos. Respecto al consumo total (10-41 días, no se presentó diferencia estadística (P > 0,05 entre n y el control; y cuando se evaluó la conversión alimenticia alcanzada para todo el período (10-41 días, no se observó diferencia entre el control y T2. El resultado más importante encontrado en este ensayo tiene que ver con la no diferencia en el peso final cuando se comparan los tratamientos de alimentación a voluntad (T1 y alimentación restringida (T2. Este hecho no debe pasar desapercibido si se tiene en cuenta que durante el período de restricción, el consumo de alimento fue menor para T2.

Full Text Available The mechanical behaviour by tensile strength test from room temperature to 350 ºC in the rapidly solidified Mg-10Ni-10Y (at. % ribbon has been studied. To determine the effect of yttrium additions the results are compared with those of Mg-11Ni studied in a previous work. Before studding the mechanical behavior of the material the thermal stability of the amorphous ribbon and the crystallization reactions were determined by DSC experiments. Results show that yttrium stabilizes the amorphous phase but it has not reinforcement effect. The tensile strength and elongation to failure values of the ternary alloy are lower than those of Mg-11Ni
El objetivo de este estudio es la caracterización mecánica, mediante ensayos de tracción, desde temperatura ambiente hasta 350 °C, de una aleación amorfa de composición Mg-10Ni-10Y (% at. obtenida mediante solidificación rápida por la técnica de la rueda. Se analiza la influencia de la adición de itrio al Mg-Ni para lo cual los resultados se comparan con los de la aleación binaria Mg-11Ni estudiada previamente. Antes de iniciar la caracterización mecánica del material, se realizó un estudio mediante calorimetría diferencial de barrido para comprobar la naturaleza amorfa de la cinta, analizar su estabilidad térmica y conocer las transformaciones que experimenta hasta la cristalización. Los resultados indican que el itrio es un estabilizador de la fase amorfa pero no mejora las propiedes mecánicas de la cinta binaria. Los valores de resistencia mecánica y alargamiento a rotura medidos en la cinta con itrio son menores que los obtenidos para la aleación binaria. -

2003-01-01
Full Text Available El riesgo de la asistencia sanitaria en general, especialmente el motivado por los errores de medicación, es un grave problema con gran repercusión humana, asistencial y económica, que está siendo abordado de forma prioritaria por las autoridades sanitarias de algunos países. Sin embargo, en España no se ha tomado conciencia de su trascendencia, aunque su magnitud en nuestro país sea similar a la de los países de su entorno. Las actividades de los gestores de riesgos en los centros sanitarios están evolucionando, adoptando una actitud más preventiva y anticipativa, que supone la colaboración con otros profesionales sanitarios en el desarrollo de programas de prevención de riesgos, entre ellos los de prevención de errores de medicación. En este artículo se describen los principales fundamentos de las estrategias de mejora de la seguridad y se expone el esquema de un programa de gestión de riesgos aplicado a la prevención de los errores de medicación a nivel hospitalario. En resumen, se postula que los gestores de riesgos formen parte de un equipo que debe analizar las causas de los incidentes que se producen, utilizar la información para implantar acciones de mejora, e introducir los principios de gestión de riesgos de una forma integral en las actividades y en la cultura de las organizaciones para, en definitiva, crear y mantener cambios significativos en los sistemas que mejoren la calidad de la prestación de servicios sanitarios y la seguridad de los pacientes.

Incidental mood state before dissonance induction affects attitude change.
Directory of Open Access Journals (Sweden)
Marie-Amélie Martinie
Full Text Available The way that incidental affect impacts attitude change brought about by controlled processes has so far been examined when the incidental affective state is generated after dissonance state induction. We therefore investigated attitude change when the incidental mood occurs prior to dissonance state induction. We expected a negative mood to induce systematic processing, and a positive mood to induce heuristic processing. Given that both systematic processing and attitude change are cognitively costly, we expected participants who experienced the dissonance state in a negative mood to have insufficient resources to allocate to attitude change. In our experiment, after mood induction (negative, neutral or positive, participants were divided into low-dissonance and high-dissonance groups. They then wrote a counterattitudinal essay. Analysis of their attitudes towards the essay topic indicated that attitude change did not occur in the negative incidental mood condition. Moreover, written productivity-one indicator of cognitive resource allocation-varied according to the type of incidental mood, and only predicted attitude change in the high-dissonance group. Our results suggest that incidental mood before dissonance induction influences the style of information processing and, by so doing, affects the extent of attitude change.

Ultrasound is commonly used to evaluate the cervical region in dogs with hypercalcemia due to suspected hyperparathyroidism. Incidental thyroid nodules may be detected during these studies, however little information has been published to guide clinical decision-making when this occurs. The purpose of this cross-sectional study was to determine the prevalence of incidental thyroid nodules in hypercalcemic dogs undergoing cervical ultrasound at our hospital during the period of 2008-2013. Dogs with a palpable neck mass were excluded. Cervical ultrasound images for each dog were retrieved and reviewed by a board certified veterinary radiologist who was unaware of patient outcome. Presence, number, and dimensions of thyroid nodules were recorded. Results of thyroid nodule aspirate, biopsy or necropsy were recorded from medical records when available. Ninety-one dogs met inclusion criteria. Of these, 14/91 (15%) dogs had at least one thyroid nodule. Mean (± standard deviation) thyroid gland nodule length, width, and height were 1.51 ± 0.74, 0.96 ± 0.73, and 0.75 ± 0.36 cm, respectively. A histologic diagnosis was available for the incidental thyroid lesions in eight dogs, including one dog with two nodules. Confirmed diagnoses for these nodules were thyroid cyst (3/9, 33%), thyroid adenoma (3/9, 33%), thyroid adenocarcinoma (2/9, 22%) and nodular hyperplasia (1/9, 11%). Findings indicated that incidental thyroid nodules may be present in hypercalcemic dogs with no palpable neck mass and no clinical signs of thyroid disease. Some of these nodules may be malignant and therefore a recommendation for cytology or biopsy may be justified. © 2014 American College of Veterinary Radiology.

To assess correlation between attenuation measurements of incidental findings in abdominal second generation dual-energy computed tomography (CT) on true noncontrast (TNC) and virtual noncontrast (VNC) images. Sixty-three patients underwent arterial dual-energy CT (Somatom Definition Flash, Siemens; pitch factor, 0.75-1.0; gantry rotation time, 0.28 seconds) after endovascular aneurysm repair, consisting of a TNC single energy CT scan (collimation, 128 × 0.6 mm; 120 kVp) and a dual-energy arterial phase scan (collimation, 32 × 0.6 mm, 140 and 100 kVp; blended, 120 kVp data set). Attenuation measurements in Hounsfield units (HU) of liver parenchyma and incidental findings like renal and hepatic cysts and adrenal masses on TNC and VNC images were done by drawing regions of interest. Statistical analysis was performed by paired t test and Pearson correlation. Incidental findings were detected in 56 (89%) patients. There was excellent correlation for both renal (n = 40) and hepatic cysts (n = 12) as well as adrenal masses (n = 6) with a Pearson correlation of 0.896, 0.800, and 0.945, respectively, and mean attenuation values on TNC and VNC images of 10.6 HU ± 12.8 versus 5.1 HU ± 17.5 (attenuation value range from -8.8 to 59.1 HU vs -11.8 to 73.4 HU), 6.4 HU ± 5.8 versus 6.3 HU ± 4.6 (attenuation value range from 2.0 to 16.2 HU vs -3.0 to 15.9 HU), and 12.8 HU ± 11.2 versus 12.4 HU ± 10.2 (attenuation value range from -2.3 to 27.5 HU vs -2.2 to 23.6 HU), respectively. As proof of principle, liver parenchyma measurements also showed excellent correlation between TNC and VNC (n = 40) images with a Pearson correlation of 0.839 and mean attenuation values on TNC and VNC images of 47.2 HU ± 10.5 versus 43.8 HU ± 8.7 (attenuation value range from 21.9 to 60.2 HU vs 4.5 to 65.3 HU). In conclusion, attenuation measurements of incidental findings like renal cysts or adrenal masses on TNC and VNC images derived from second generation dual-energy CT scans show excellent

Reports an error in "Incidental fear cues increase monetary loss aversion" by Stefan Schulreich, Holger Gerhardt and Hauke R. Heekeren ( Emotion , 2016[Apr], Vol 16[3], 402-412). In the current article, there was an error in the Study 2 portion of the article. The fourth paragraph of the Results section should read as follows: Performing the same analyses as in Study 1, we found an effect of incidental fear cues on decision behavior. Participants accepted fewer gambles in the fearful-face condition (32.77%) than in the neutral-face condition (33.96%), with Z = -2.187, p = .027, d = -0.998 in the Wilcoxon signed-ranks test and β = 0.012, SE = 0.0053, F(1, 21) = 4.434, p = .047, partial η² = .174 in the linear regression. This suggests increased risk aversion in the fearful-face condition. Concerning personality, however, there were no significant between-subjects effects or between-within interaction effects (all ps = .349). (The following abstract of the original article appeared in record 2015-52358-001.) In many everyday decisions, people exhibit loss aversion-a greater sensitivity to losses relative to gains of equal size. Loss aversion is thought to be (at least partly) mediated by emotional-in particular, fear-related-processes. Decision research has shown that even incidental emotions, which are unrelated to the decision at hand, can influence decision making. The effect of incidental fear on loss aversion, however, is thus far unclear. In two studies, we experimentally investigated how incidental fear cues, presented during (Study 1) or before (Study 2) choices to accept or reject mixed gambles over real monetary stakes, influence monetary loss aversion. We find that the presentation of fearful faces, relative to the presentation of neutral faces, increased risk aversion-an effect that could be attributed to increased loss aversion. The size of this effect was moderated by psychopathic personality: Fearless dominance, in particular its interpersonal facet

Metal contacts on ZnSe and GaN
Energy Technology Data Exchange (ETDEWEB)
Duxstad, Kristin Joy [Univ. of California, Berkeley, CA (United States). Materials Science and Mineral Engineering
1997-05-01
Recently, considerable interest has been focused on the development of blue light emitting materials and devices. The focus has been on GaN and ZnSe, direct band gap semiconductors with bands gaps of 3.4 and 2.6 eV, respectively. To have efficient, reliable devices it is necessary to have thermally and electrically stable Ohmic contacts. This requires knowledge of the metal-semiconductor reaction behavior. To date few studies have investigated this behavior. Much information has accumulated over the years on the behavior of metals on Si and GaAs. This thesis provides new knowledge for the more ionic wide band gap semiconductors. The initial reaction temperatures, first phases formed, and phase stability of Pt, Pd, and Ni on both semiconductors were investigated. The reactions of these metals on ZnSe and GaN are discussed in detail and correlated with predicted behavior. In addition, comparisons are made between these highly ionic semiconductors and Si and GaAs. The trends observed here should also be applicable to other II-VI and III-Nitride semiconductor systems, while the information on phase formation and stability should be useful in the development of contacts for ZnSe and GaN devices.

Negative incidental emotions augment fairness sensitivity.
Liu, Cuizhen; Chai, Jing Wen; Yu, Rongjun
2016-04-22
Previous studies have shown that task-unrelated emotions induced incidentally exert carryover effects on individuals' subsequent decisions in financial negotiations. However, the specificity of these emotion effects are not clear. In three experiments, we systematically investigated the role of seven transiently induced basic emotions (disgust, sadness, anger, fear, happiness, surprise and neutral) on rejection of unfair offers using the ultimatum game. We found that all negative emotions (disgust, sadness, anger and fear), but not happiness or surprise, significantly increased rejection rates, suggesting that the effect of incidental negative emotions on fairness is not specific to the type of negative emotion. Our findings highlight the role of fleeting emotions in biasing decision-making processes and suggest that all incidental negative emotions exert similar effects on fairness sensitivity, possibly by potentiating attention towards negative aspects of the situation.

IL-29 Enhances CXCL10 Production in TNF-α-stimulated Human Oral Epithelial Cells.
Hosokawa, Yoshitaka; Hosokawa, Ikuko; Shindo, Satoru; Ozaki, Kazumi; Matsuo, Takashi
2017-08-01
Interleukin-29 (IL-29) is a cytokine belonging to the Type III interferon family. It was recently detected in the gingival crevicular fluid of periodontitis patients. However, the role of IL-29 in the pathogenesis of periodontal disease remains unknown. The aim of this study was to examine the effects of IL-29 on C-X-C motif chemokine ligand 10 (CXCL10) production in human oral epithelial cells. We measured CXCL10 production in TR146 cells, which is a human oral epithelial cell line, using an enzyme-linked immunosorbent assay. We used a Western blot analysis to detect IL-29 receptor expression and the phosphorylation levels of signal transduction molecules, including p38 mitogen-activated protein kinases (MAPK), signal transducer and activator of transcription 3 (STAT3), and nuclear factor (NF)- κB p65, in the TR146 cells. The TR146 cells expressed the IL-29 receptor. IL-29 induced CXCL10 production in the TR146 cells. IL-29 significantly enhanced CXCL10 production in tumor necrosis factor (TNF)-α-stimulated TR146 cells. The p38 MAPK, STAT3, and NF-κB pathways were found to be related to the IL-29-induced enhancement of CXCL10 production in TNF-α-stimulated TR146 cells. IL-29 promotes T helper 1-cell accumulation in periodontal lesions by inducing CXCL10 production in oral epithelial cells.

Ti2Nb10O29 has recently been reported as a promising anode material for lithium-ion batteries. However, its poor electronic conductivity and insufficient Li+-ion diffusion coefficient significantly limit its rate capability. To tackle this issue, a strategy combining nanosizing and crystal-structure modification is employed. Ti2Nb10O29-x mesoporous microspheres with a sphere-size range of 0.5-4 μm are prepared by a one-step solvothermal method followed by thermal treatment in N2. These Ti2Nb10O29-x mesoporous microspheres exhibit primary nanoparticles, a large specific surface area (22.9 m2 g-1) and suitable pore sizes, leading to easy electron/Li+-ion transport and good interfacial reactivity. Ti2Nb10O29-x shows a defective shear ReO3 crystal structure with O2- vacancies and an increased unit cell volume, resulting in its increased Li+-ion diffusion coefficient. Besides Ti4+ and Nb5+ ions, Ti2Nb10O29-x comprises Nb4+ ions with unpaired 4d electrons, which significantly increase its electronic conductivity. As a result of these improvements, the Ti2Nb10O29-x mesoporous microspheres reveal superior electrochemical performances in term of large reversible specific capacity (309 mAh g-1 at 0.1 C), outstanding rate capability (235 mAh g-1 at 40 C) and durable cyclic stability (capacity retention of 92.1% over 100 cycles at 10 C).

The aim of the current study was to investigate the impact of gender and age on incidental and intentional memory in healthy participants and to explore the strength of the association of incidental and intentional memory with attentional and executive functioning. A total number of 47 participants underwent a driving simulation experiment and went through detailed neuropsychological testing. Incidental memory was assessed with a questionnaire that evaluated the memorization of information related to the driving simulator task while intentional memory was assessed using the Hopkins Verbal Learning Test-Revised and the Brief Visuospatial Memory Test-Revised. The analysis revealed a greater impact of age on incidental as compared to intentional memory. Gender did not appear to have such an effect on either incidental or intentional memory. Finally, attentional and executive functioning were more strongly associated with incidental memory than the intentional memory measures that were utilized in the current study. Ageing appears to affect incidental rather than intentional memory to a greater extent. In addition, attentional and executive functioning seem to play a more important role in incidental than intentional encoding and consolidation processes. © The Author 2017.

Impact of lymphocytic thyroiditis on incidence of pathological incidental thyroid carcinoma.
Farrell, Eric; Heffron, Cynthia; Murphy, Matthew; O'Leary, Gerard; Sheahan, Patrick
2017-01-01
The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cytology. We excluded 65 cases because of preoperative diagnosis of thyroid cancer, and 68 because of nonincidental cancer within the index nodule. Among the remaining 580 cases, there were 43 cases (7.4%) of incidental thyroid cancers. Incidental thyroid cancers were significantly associated with moderate/severe lymphocytic thyroiditis (relative risk = 2.5; p = .03). Sixteen of 56 patients with moderate/severe lymphocytic thyroiditis had Graves' disease, none of whom had incidental thyroid cancer. The risk of incidental thyroid cancer associated with moderate/severe lymphocytic thyroiditis was significantly higher in non-Graves' than patients with Graves' disease (p = .05). The risk of incidental thyroid cancer is significantly increased in patients with moderate/severe lymphocytic thyroiditis. Moderate/severe lymphocytic thyroiditis associated with Graves' disease seems to have a lower risk of incidental thyroid cancer. © 2016 Wiley Periodicals, Inc.

N and Si implantation to GaSe single crystals were carried out parallel to c-axis with ion beam of about 10 1 6 ions/cm 2 dose having energy values 30, 60 and 100 keV. Ion implantation modifications on Bridgman grown GaSe single crystals have been investigated by means of XRD, electrical conductivity, absorption and photoconductivity measurements. XRD measurements revealed that annealing results in a complete recovery of the crystalline nature that was moderately reduced upon implantation. It was observed that both N- and Siimplantation followed by annealing process decreased the resistivity values from 10 7 to 10 3 .-cm. The analysis of temperature dependent conductivity showed that at high temperature region above 200 K, the transport mechanism is dominated by thermal excitation in the doped and undoped GaSe samples. At lower temperatures, the conduction of carriers is dominated by variable range hopping mechanism in the implanted samples. Absorption and spectral photoconductivity measurements showed that the band edge is shifted in the implanted sample. All these modifications were attributed to the structural modifications and continuous shallow trap levels introduced upon implantation and annealing

Full Text Available Myxomas are mesenchymal tumors commonly found in the heart and skin. Renal myxomas are rare, having only been documented 14 times. Our case is a 55-year-old woman who presented to our clinic after a right renal mass was incidentally found on CT. Evaluation with MRI showed a mass that appeared to arise from the supero-medial cortex of the right kidney. As the imaging was concerning for renal cell carcinoma, the patient underwent a partial nephrectomy. Microscopic examination showed a well-circumscribed mass with polygonal to spindle-shaped cells in a granular eosinophilic cytoplasm. Immunohistochemical staining for CD-10, Desmin, HMB-45, and Pankeratin were negative.

Concern for a diminished human experience of nature and subsequent decreased human well-being is addressed via a consideration of green infrastructure's potential to facilitate unplanned or incidental nature experience. Incidental nature experience is conceptualized and illustrated in order to consider this seldom addressed aspect of human interaction with nature in green infrastructure planning. Special attention has been paid to the ability of incidental nature experience to redirect attention from a primary activity toward an unplanned focus (in this case, nature phenomena). The value of such experience for human well-being is considered. The role of green infrastructure to provide the opportunity for incidental nature experience may serve as a nudge or guide toward meaningful interaction. These ideas are explored using examples of green infrastructure design in two Nordic municipalities: Kristianstad, Sweden, and Copenhagen, Denmark. The outcome of the case study analysis coupled with the review of literature is a set of sample recommendations for how green infrastructure can be designed to support a range of incidental nature experiences with the potential to support human well-being.

Otero López María José
2003-01-01
Full Text Available El riesgo de la asistencia sanitaria en general, especialmente el motivado por los errores de medicación, es un grave problema con gran repercusión humana, asistencial y económica, que está siendo abordado de forma prioritaria por las autoridades sanitarias de algunos países. Sin embargo, en España no se ha tomado conciencia de su trascendencia, aunque su magnitud en nuestro país sea similar a la de los países de su entorno. Las actividades de los gestores de riesgos en los centros sanitarios están evolucionando, adoptando una actitud más preventiva y anticipativa, que supone la colaboración con otros profesionales sanitarios en el desarrollo de programas de prevención de riesgos, entre ellos los de prevención de errores de medicación. En este artículo se describen los principales fundamentos de las estrategias de mejora de la seguridad y se expone el esquema de un programa de gestión de riesgos aplicado a la prevención de los errores de medicación a nivel hospitalario. En resumen, se postula que los gestores de riesgos formen parte de un equipo que debe analizar las causas de los incidentes que se producen, utilizar la información para implantar acciones de mejora, e introducir los principios de gestión de riesgos de una forma integral en las actividades y en la cultura de las organizaciones para, en definitiva, crear y mantener cambios significativos en los sistemas que mejoren la calidad de la prestación de servicios sanitarios y la seguridad de los pacientes.

Full Text Available Este trabajo busca proveer un vocabulario crítico respecto de la relación entre sociedad, tecnología e innovación, a efectos de informar el diseño de políticas públicas de innovación orientadas a promover mayores grados de inclusión social. Si bien se espera que el desarrollo tecnológico y la innovación sean factores que colaboren con la edificación de una sociedad próspera, no existe una asociación lineal, puesto que las relaciones sociales del cambio técnico son, en definitiva, relaciones de poder. Tomando como punto de partida el hecho de que la tecnología edifica estructuras materiales y culturales que modifican las prácticas sociales, este trabajo examina cuáles son algunos de los elementos respecto del diseño de políticas públicas e intervención del estado que deberían considerarse para relacionar las innovaciones tecnológicas con la inclusión social.AbstractThis paper seeks to provide a critical vocabulary about the relationships between society, technology, and innovation, for informing the design of innovation policies geared towards greater degrees of social inclusion. Although it is expected that technological development and innovation should become factors bringing about a more prosperous society, there is no linear association between them because the social relations surrounding technological change are, after all, power relations. Taking as a starting point the fact that technology builds material and cultural structures that transform social practices deeply, this paper examines some of the issues related to public policy design and state intervention that ought to be considered in order to link technological innovations with social inclusion.

Incidental fear cues increase monetary loss aversion.
Schulreich, Stefan; Gerhardt, Holger; Heekeren, Hauke R
2016-04-01
In many everyday decisions, people exhibit loss aversion-a greater sensitivity to losses relative to gains of equal size. Loss aversion is thought to be (at least partly) mediated by emotional--in particular, fear-related--processes. Decision research has shown that even incidental emotions, which are unrelated to the decision at hand, can influence decision making. The effect of incidental fear on loss aversion, however, is thus far unclear. In two studies, we experimentally investigated how incidental fear cues, presented during (Study 1) or before (Study 2) choices to accept or reject mixed gambles over real monetary stakes, influence monetary loss aversion. We find that the presentation of fearful faces, relative to the presentation of neutral faces, increased risk aversion-an effect that could be attributed to increased loss aversion. The size of this effect was moderated by psychopathic personality: Fearless dominance, in particular its interpersonal facet, but not self-centered impulsivity, attenuated the effect of incidental fear cues on loss aversion, consistent with reduced fear reactivity. Together, these results highlight the sensitivity of loss aversion to the affective context. (c) 2016 APA, all rights reserved).

Purpose: To report the results of high-dose conformal irradiation and examine incidental nodal irradiation and nodal failure in patients with inoperable early-stage non-small-cell lung cancer (NSCLC). Methods and Materials: This analysis included patients with inoperable CT-staged T1-3N0M0 NSCLC treated on our prospective dose-escalation trial. Patients were treated with radiation alone (total dose, 63-102.9 Gy in 2.1-Gy daily fractions) with a three-dimensional conformal technique without intentional nodal irradiation. Bilateral highest mediastinal and upper/lower paratracheal, prevascular and retrotracheal, sub- and para-aortic, subcarinal, paraesophageal, and ipsilateral hilar regions were delineated individually. Nodal failure and doses of incidental irradiation were studied. Results: The potential median follow-up was 104 months. For patients who completed protocol treatment, median survival was 31 months. The actuarial overall survival rate was 86%, 61%, 43%, and 21% and the cause-specific survival rate was 89%, 70%, 53%, and 35% at 1, 2, 3, and 5 years, respectively. Weight loss (p = 0.008) and radiation dose in Gy (p = 0.013) were significantly associated with overall survival. In only 22% and 13% of patients examined did ipsilateral hilar and paratracheal (and subaortic for left-sided tumor) nodal regions receive a dose of ≥40 Gy, respectively. Less than 10% of all other nodal regions received a dose of ≥40 Gy. No patients failed initially at nodal sites. Conclusions: Radiation dose is positively associated with overall survival in patients with medically inoperable T1-3N0 NSCLC, though long-term results remain poor. The nodal failure rate is low and does not seem to be due to high-dose incidental irradiation

Full Text Available Este trabajo describe y da los resultados obtenidos con el pretratamiento de estacones de Eucalyptus saligna a tres soluciones de CUS04 y su posterior tratamiento con sales CCA (OSMOSE K-33. El sulfato de cobre se aplicó por el método de baño caliente y frío, seguido por el proceso de difusión durante una semana; para los anteriores tratamientos se usó madera verde o parcialmente seca al aire; las sales CCA se aplicaron a madera seca por el método de vacío-presión. Una de las razones para llevar a cabo este refuerzo de las sales CCA, es haber encontrado postes de eucalipto severamente atacados por hongos, en especial con pudrición blanda. Los estacones fueron tratados inicialmente con soluciones de sulfato de cobre a 1 %, 2% y 3% de concentración; luego los estacones fueron tratados con una solución de sal CCA al 2.5% de concentración por vacío-presión. Se usaron 40 estacones distribuídos en 4 grupos de 10: tres (3 grupos fueron usados para el tratamiento con las soluciones de CUS04 y solución de CCA; el grupo restante fue tratado con la sal CCA únicamente, el cual fue usado como grupo testigo para fines de comparación en los ensayos de campo (cementerios.

Full Text Available Nitriding is one of the most used techniques to enhance the life in service of forming tools. In this study high pressure gas nitriding technology has been applied in warm and cold forming tools. The utilisation of high pressure enhances the nitriding effect of the NH3 atmosphere and several advantages arise comparing with conventional techniques. Besides of this, in the framework of this project, several ecological lubricants have been developed to be used in both forming applications and the interaction of these products with the nitrurated surfaces has been study. Specifically, it was studied the introduction of a vegetable oil with graphite for warm forging and several phosphorlubricating oils to be applied in pieces for a cold forming transformation. In a first stage this analysis was carried out in a laboratory by means of tribological tests and lately in field tests.
Una de las técnicas más empleadas para mejorar la vida de las herramientas de conformado es la nitruración. En el presente estudio se ha empleado la tecnología de nitruración gaseosa a alta presión aplicada a utillaje de forja en semicaliente y calibrado en frío. La utilización de presiones elevadas potencia el efecto nitrurante de la atmósfera de NH3, por lo tanto presenta una serie de ventajas frente a otras técnicas convencionales. Además, en el marco de este trabajo, se han desarrollado diferentes lubricantes ecológicos para su utilización en estas aplicaciones de conformado y se ha analizado la interacción de estos productos con las superficies nitruradas. En concreto se ha estudiado la introducción de un lubricante grafitado en base vegetal para forja en semicaliente y de varios aceites fosfolubricantes para piezas que sufrirán una transformación en frío. Este análisis se ha llevado a cabo inicialmente en el laboratorio mediante diversos ensayos tribológicos y finalmente en pruebas de campo. -

Full Text Available EPIC es un estudio prospectivo multicéntrico coordinado por la Agencia Internacional de Investigación del Cancer (IARC de la OMS, que se inició en 1993 con la recogida de datos y muestras de sangre en 23 centros de 10 países europeos: Alemania, Dinamarca, España, Francia, Grecia, Holanda, Italia, Noruega, Reino Unido y Suecia, En España se realiza en 5 áreas geográficas: Asturias, Granada, Guipúzcoa, Murcia y Navarra. Se incluyeron en la cohorte 519.978 individuos (de los cuales 366.521 son mujeres y en 385.719 de ellos se dispone de muestras de sangre por análisis de laboratorio. Hasta la fecha se han identificado 24.195 casos incidentes de cáncer. Los resultados de la comparación del consumo alimentario entre los 23 centros europeos se han publicado en el 2002, en un suplemento de una revista europea de Nutrición. Los primeros resultados obtenidos en EPIC sobre la relación de la dieta y el cáncer muestran un efecto protector del consumo de fibras, frutas y verduras sobre el cáncer colo-rectal, un efecto protector del consumo de frutas sobre el cáncer de pulmón, y de las frutas y verduras sobre el tracto digestivo superior, mientras que se ha confirmado que el alto consumo de frutas y verduras no tiene efecto sobre el cáncer de próstata. Usando un diario de 7 días para evaluar el consumo de grasas saturadas, se ha confirmado que un alto consumo de estas aumenta el riesgo de cáncer de mama.

1983-01-01
Full Text Available Día a día se está cuestionando sobre la permanencia de las condiciones que presentan los materiales empleados para la construcción de obras civiles; esto resulta aun más complejo cuando se trata de materiales naturales, no tratados, provenientes de la corteza terrestre. Siempre se parte de una supuesta actividad o estabilidad de los agregados, los cuales son calificados como "inertes"; ahora se acepta plenamente que su comportamiento está lejos de tal condición y más bien encaja dentro del concepto de una acción dinámica que puede ser acelerada o atenuada en los procesos de producción y construcción y durante la vida de servicio. En el presente trabajo se analizan, someramente, los factores incidentes en la resistencia a la degradación que presentan los agregados pétreos y se hace una revisión sobre las evaluaciones que se realizan para tratar de predecir la durabilidad de los mismos y la permanencia de sus características con el tiempo.

Full Text Available El objetivo de este trabajo fue evaluar el efecto de la radiación y la temperatura a través de un cociente fototermal sobre la acumulación de azúcar en melón. Se realizaron experimentos al aire libre en tres años consecutivos, utilizándose el híbrido ´HD Nº1´, una variedad de tipo ´Honey Dew´. Los experimentos se realizaron en cuatro localidades de la región central de Argentina: Concordia, Esperanza, Media Agua y Colonia Fiscal. Al momento de la cosecha fueron medidos los grados Brix (SST de los frutos. Se calculó el cociente fototermal (CF a través de la relación entre la radiación incidente media (MJ m-2 d-1 y la temperatura media diaria (ºC a la que se sustrajo la temperatura base del cultivo. La relación obtenida entre la concentración de SST (% y el CF (MJ m-2 d-1 ºC-1 fue lineal positiva. La pendiente de la recta permitió deducir que por cada unidad de incremento del CF representó un incremento de poco más de 4,0 % de SST. Por otra parte, este modelo lineal explica el 63 % de la variabilidad en la concentración de SST debida al efecto del CF. Finalmente, para lograr un incremento de los SST se discute la importancia de los resultados obtenidos para orientar la implantación del cultivo de manera que el desarrollo de los frutos coincida con el período de mayor valor de CF.

Full Text Available Ante las transformaciones del capitalismo, las organizaciones empresariales2 propician formas de gestión que, les permiten conservar e incrementar sus utilidades y asegurar su lugar en el mercado. Se considera que, a través de sus prácticas, estas organizaciones ejercen una forma de poder mediante la cual producen ciertos tipos de subjetividades útiles a sus propósitos. El objetivo de la investigación es comprender la incidencia de la organización empresarial en la subjetividad de los empleados y las implicaciones ante la ruptura laboral. Mediante una estrategia metodológica de estudio de caso con enfoque cualitativo y narrativo, se da cuenta del fenómeno de estudio. Como hallazgo relevante se logró determinar los elementos contextuales que facilitan el protagonismo de la organización empresarial como referente significativo e incidente en la conformación de subjetividades. También se reconocieron dispositivos desplegados por la empresa que obraron dicho proceso, así como sentimientos de transgresión ante la inminente ruptura laboral.

We propose using amorphous Zn–Sn–O (α-ZTO) deposited by RF sputtering as an alternative n-type buffer layer for Cu(In,Ga)Se 2 and SnS solar cells. The order of the carrier density, n, is increased from the order of 10 15 to 10 17 cm −1 as the Sn/(Sn + Zn) atomic ratio increases from 0.29 to 0.40. On the other hand, the order of n decreased from 10 17 to 10 11 cm −1 as the oxygen partial pressure increased from 0 to 10%. Further, for the α-ZTO film with the Sn/(Sn + Zn) atomic ratio at 0.38 and the oxygen partial pressure at 0%, valence band discontinuities of α-ZTO/CuInSe 2 and α-ZTO/SnS were determined using photoelectron yield spectroscopy measurements. The band discontinuities of each of these interfaces form a spike structure in the conduction band offset, which enables a high-performance solar cell to be obtained. - Highlights: • We propose using amorphous Zn–Sn–O as a n-type layer for Cu(In,Ga)Se 2 and SnS solar cells. • The carrier density was controlled by total and/or oxygen partial pressure during sputtering. • Valence band discontinuities of Zn–Sn–O/CuInSe 2 and Zn–Sn–O/SnS were determined. • The conduction band discontinuities of each of these interfaces form a spike structure
