The helium spread in the Globular cluster 47 Tuc

Spectroscopy has shown the presence of the CN band dicothomy and the Na-O anticorrelations for 50--70% of the investigated samples in the cluster 47 Tuc, otherwise considered a "normal" prototype of high metallicity clusters from the photometric analysis. Very recently, the re-analysis of a large number of archival HST data of the cluster core has been able to put into evidence the presence of structures in the Sub Giant Branch: it has a brighter component with a spread in magnitude by $\sim$0.06 mag and a second one, made of about 10% of stars, a little fainter (by $\sim$0.05 mag). These data also show that the Main Sequence of the cluster has an intrinsic spread in color which, if interpreted as due to a small spread in helium abundance, suggests $\Delta$Y$\sim$0.027. In this work we examine in detail whether the Horizontal Branch morphology and the Sub Giant structure provide further independent indications that a real --although very small-helium spread is present in the cluster. We re--analyze the HST archival data for the Horizontal Branch of 47 Tuc, obtaining a sample of $\sim$500 stars with very small photometric errors, and build population synthesis based on new models to show that its particular morphology can be better explained by taking into account a spread in helium abundance of 2% in mass. The same variation in helium is able to explain the spread in luminosity of the Sub Giant Branch, while a small part of the second generation is characterized by a small C+N+O increase and provides an explanation for the fainter Sub Giant Branch. We conclude that three photometric features concur to form the paradigm that a small but real helium spread is present in a cluster that has no spectacular evidence for multiple populations like those shown by other massive clusters.Comment: Accepted for publication in the MNRAS on 2010 June 8.

Recognizable neonatal clinical features of aplasia cutis congenita

Background: Aplasia cutis congenita (ACC), classified in nine groups, is likely to be underreported, since milder isolated lesions in wellbeing newborns could often be undetected, and solitary lesions in the context of polymalformative syndromes could not always be reported. Regardless of form and cause, therapeutic options have in common the aim to restore the deficient mechanical and immunological cutaneous protection and to limit the risk of fluid leakage or rupture of the exposed organs. We aimed to review our institutional prevalence, comorbidities, treatment and outcome of newborns with ACC. Methods: We conducted a retrospective study including all newborns affected by ACC and admitted at the University Mother-Child Department from October 2010 to October 2019. Anthropometric and clinical characteristics of ACC1 versus a non-isolated ACC group were analyzed. Results: We encountered 37 newborns, 16 with ACC1 versus 21 with non-isolated ACC. The incidence rate of 0.1% in ACC1 was higher than expected, while 19% of cases showed intrafamilial autosomal dominant transmission. Higher birth weight centile, though lower than reference population, being adequate for gestational age, normal Apgar score and euglycemia characterizing ACC1 resulted associated to a rapid tissue regeneration. Non-isolated ACC, in relation to concomitant congenital anomalies and higher prematurity rate, showed more surgical and medical complications along with the risk of neonatal death. Specifically, newborns with ACC4 were characterized by the frequent necessity of abdominal wall defect repair, responsible for the occurrence of an abdominal compartment syndrome. Conclusion: Prompt carefully assessment of the newborn with ACC in order to exclude concomitant other congenital malformations, provides clues to the underlying pathophysiology, and to the short-term prognosis. Family should be oriented toward identification of other family members affected by similar pathology, while obstetric history should exclude initial multiple pregnancy with death of a co-twin, placental anomalies and drug assumption.

Análise espacial das mudanças na cobertura e uso das terras em Santarém e Belterra, Pará, Brasil: armadilhas metodológicas associadas.

Através de um estudo de caso, indicamos como a delimitação da área de estudo pode influenciar o resultado de análises multiescalares em processos espaciais de mudanças na cobertura e uso da terra na Amazônia. Partindo dos limites dos municípios de Santarém e Belterra no oeste do Estado do Pará, definimos três níveis de delimitação da área de estudo. O primeiro nível abrange uma região que foi arbitrariamente definida e denominada sub-região de Santarém e Belterra. O segundo nível, uma parte do primeiro, corresponde ao limite do entorno de lotes estabelecidos pelo INCRA na década de 1970, tratando-se portanto de uma área de ocupação consolidada. O terceiro nível corresponde às zonas de influência de quatro eixos viários inseridos dentro da área de ocupação consolidada, subdivididos em subáreas norte e sul, num total de oito subáreas do segundo nível de delimitação. Para cada nível, aplicamos métricas de paisagem sobre mapeamentos temáticos do satélite Landsat obtidos para os anos de 1986 a 2005 e as associamos com dados sociodemográficos obtidos em levantamentos realizados em 2003. Os resultados mostram que as peculiaridades da dinâmica de ocupação em cada nível permitem melhor identificar padrões e processos na composição da estrutura da paisagem. Os dados obtidos para os três níveis de delimitação são complementares, possibilitando uma compreensão mais abrangente do que aquela que se poderia obter pelo estudo de um único nível

Inclusiones fluidas en el yacimiento aurífero de "El Cabaco" provincia de Salamanca

[Resumen] En este estudio se caracterizan las inclusiones fluidas en filones de cuarzo del área mineralizada de El Cabaco, asociados al granito hercínico de La Alberca-Sequeros en su borde noroccidental (Sur de la provincia de Salamanca). En los filones mineralizados, a lo largo de los planos de crecimiento del cuarzo, se han observado dos tipos principales de inclusiones fluidas desde un punto de vista composiciona1. Uno de ellos (tipo A) es rico en CH4, con cantidades menores de C02, y el otro (tipo B) es rico en H20 con C02 (± CH4). Estos datos se interpretan como el resultado de un fenómeno de inmiscibilidad de un fluido inicial rico en H20-CH4 y con algo de C02. También se han observado otras inclusiones (tipo C), grandes y abundantes (claramente secundarias) principalmente de dos fases, ricas en H20 y a veces con inclusiones minerales. En las zonas silicificadas o de greisen en torno a los filones, así como en un dique granítico, las inclusiones fluidas tienen una composición similar a la de los cuarzos filonianos. Sin embargo se han deducido temperaturas en formación de 485 ± 15°C para el dique granítico y el greisen y presiones algo menores a 1 Kb; los filones de cuarzo se formaron a temperaturas que no exceden 386°C y presiones menores de < 300 bares.[Abstract] This study characterizes fluid inclusions in veins associated with the emplacement of granite-hosted gold mineralization in the southern pan of the Province of Salamanca Spain. Within the mineralized veins, along planes of quanz growth, two main different compositional types of fluid inclusions were observed. One type (A) is rich in CH4, with minar C02, and the type (B) is rich in H20 with C02 (± CH4). These are interpreted as reflecting the inmiscibility of an initial fluid rich in H20CH4 and sorne C02. Large and abundant (cleary secondary) mainly two phase H20 rich inclusions (Type C) have seen observed also. Similar composition inclusion are seen in the granite cross-cutting vein mineralization and in the silification with mineralization of the greisen formed in a gra nitie dike. However, differenees regardin P-T conditions of formation have been dedueed from the interseetion of the isoehores obtained in the mierothermometrie study of the inclusions. These are eonsistent with the temperatures ealculated from the arsenopyrite-pyrite geothemometer (after mieroprobe measurement). Formation temperatures of 485 ± 15°C were dedueed for the mineralization in the greisen of the granitie dike and pressures under 1 x 108 Pa. The veins were formed at temperatures not exeeeding 386°C and < 300 x 105 Pa pressureFluid inclusions in the auriferous «El Cabaco» zone, Salamanca province, Spai

Geochemical clistribution of An in granites with locle mineralizations in As, W ancl Au (NW of Salamanca)

[Resumen] Ante las pruebas de la existencia de altas incidencias de cáncer de próstata en una zona de la provincia de Salamanca y habiendo descartado los factores etiológicos más comunes como su posible causa (MAYOR ARENAL, 1988), se concluye que el único factor de riesgo posible se debería a la existencia de algún factor carcinógeno ambiental. Se realizó una prospección geoquímica de Cd en esta zona dada la relación etiológica de este elemento con dicha enfermedad y se ha constatado que efectivamente existe una anomalía de Cd en los sedimentos de arroyo, que no se corresponde con actividades antropogénicas, sino que son anomalías regionales de los contenidos propios de este elemento en el sustrato, evidenciándose así como potencial factor de riesgo los contenidos de Cd en los suelos desarrollados sobre rocas anómalas en dicho elemento.[Abstract] A high ineidence of prostate cancer has been observed in certain areas of the province of Salamanca. Spain. Mter ruling out the most common etiological factors as the cause (MAYOR ARENAL, 1988) it is concluded that the only possible risk factor must be due to the presence of some environmental carcinogen. In view of the etiological relationship between Cd and the patological state, a study was carried out on the geochemistry of this element in this area. Anomalous amounts of Cd were found in stream sediments and it was observed that this anomaly does not correspond to human activity but rather to high regional amounts of cadmium in the substrate. Thus, the contents of Cd in soils developed over substrates containing naturally-ocurring anomalous amounts of cadmiun should be considered as a real new risk factor

P02-270 Study of the correlations between theory of mind, symptoms and personality characteristics of a non-psychiatric population

Aims:A deficit in the theory of mind has been identified, although without univocal results, in various pathologies, such as schizophrenia, bipolar disorder and some personality disorders. Aim of the study was to evaluate, in a non- psychiatric population, the correlation of personological characteristics and symptoms with theory of mind and emotion recognition tasks.Methods:The following protocol was administrated to 130 voluntary students from Novara (Italy) School of Medicine: EPQ-R test for personality analysis; an intention-inferencing task for theory of mind (adapted from Happè's version); the emotion recognition test (adapted from Blair's version); and SCL-90 for symptoms evaluation. Spearman correlation coefficient (SC) was calculated; p< 0.05 was considered statistically significant.Results:No statistically significant correlations were found between the EPQ-R (psychoticism, estroversion and nevroticism) and theory of mind test scores. Better performances in the theory of mind test corresponded to lower scores in SCL-90 subscales: obsessive-compulsive disorder (SC:-0.248; p=0.004); depression (SC:-0.280; p=0.001); anxiety (SC:-0.276; p=0.001); hostility (SC:-0.178; p=0.042); phobic anxiety (SC:-0.197;p=0.025); paranoid ideation (SC:-0.191;p=0.03); and psychoticism (SC:-0.189; p=0.032). A lower capacity in the recognition of the happiness emotion corresponded to higher scores in the hostility (CS:-0.194; p=0.027) and phobic anxiety (CS:-0.211; p=0.016) SCL-90 subscales, while higher scores in the EPQ-R subscale psychoticism and somatisation SCL-90 subscales were respectively related to lower skills in the recognition of fear (CS:-0.226; p=0.01) and envy (CS:-0.193; p=0.028) emotions.Conclusions:Theory of mind skills seem independent from personological traits, but are inversely correlated to various symptomatological subscale scores. The recognition of specific emotions correlates selectively with various personological traits and symptomatological subscales
