1.84 micron emission of Tm3+ sensitized by Yb3+ ions in monoclinic KGd(WO4)2 single crystals

By exciting at 940 nm, we have characterized the 1.84 m near infrared emission of trivalent thulium ions in Yb3+, Tm3+:KGd WO4 2 single crystals as a function of the dopant concentration and temperature, from 10 K to room temperature. An overall 3H6 Stark splitting of 470 cm−1 for the Tm3+ ions in the Yb3+, Tm3+:KGd WO4 2 was obtained. We also studied the blue emission at 476 nm Tm3+ and the near infrared emissions at 1.48 m Tm3+ and 1 m Yb3+ as a function of the dopant concentration. Experimental decay times of the 1G4, 3H4, and 3F4 Tm3+ and 2F5/2 Yb3+ excited states have been measured as a function of Yb3+ and Tm3+ ion concentrations. For the 3F4 →3H6 transition of Tm3+ ions, we used the reciprocity method to calculate the maximum emission cross section of 3.07 10−20 cm2 at 1.84 m for the polarization parallel to the Nm principal optical direction.

Motivacions i barreres en la població de Canovelles de 65 a 84 anys al Complex Esportiu Municipal Thalassa

El present estudi s’emmarca en una investigació centrada en les persones grans de 65 a 84 anys del municipi de Canovelles. L’objectiu d’aquesta recerca és conèixer les principals motivacions i barreres d’aquest col·lectiu a l’hora d’anar al Complex Esportiu Municipal – Thalassa. Lligat amb els objectius marcats, la finalitat és relacionar els resultats amb possibles propostes de millora, per tal de minimitzar les barreres i potenciar les motivacions. Per obtenir els resultats s’ha passat un qüestionari a 40 persones demanant les raons per les quals van o no al complex. Un cop analitzats podem extreure, a tall de conclusions, que la principal motivació va relacionada amb temes de salut i la principal barrera amb temes econòmic, el cost mensual de la instal·lació per un abonat.

Dinâmica do componente arbóreo de uma mata de galeria inundável (Brasília, Distrito Federal) em um período de oito anos

(Dinâmica do componente arbóreo de uma mata de galeria inundável (Brasília, Distrito Federal) em um período de oito anos). As matas de galeria são importantes na manutenção dos recursos hídricos e da biodiversidade do Planalto Central, mas estão submetidas a fortes impactos antrópicos. Aquelas que ocorrem em solos mal drenados são pouquíssimo estudadas, com consequências negativas sobre sua conservação. Este trabalho objetivou avaliar a dinâmica florística e estrutural de um trecho de mata de galeria inundável na Fazenda Sucupira (15°54'22" S; 48°00'34" W), Brasília, Distrito Federal, em um período de oito anos (2000 a 2008). Nas duas medições realizadas, em 40 parcelas (0,8 ha) de 20 × 10 m, foram amostrados todos os indivíduos arbóreos com DAP ³ 3,0 cm. A primeira medição registrou 3.048 indivíduos, distribuídos em 50 espécies e 41 gêneros (32 famílias). Na segunda medição foram encontrados 2.728 indivíduos, pertencentes a 59 espécies e 48 gêneros (36 famílias). Em 2008 verificou-se diminuição de 320 indivíduos, mas acréscimo de 9 espécies, 7 gêneros e 4 famílias. O período monitorado revelou altas taxas de mortalidade (4,25% ano-1) e recrutamento (3,67% ano-1), mudanças consideráveis na importância de muitas espécies, sem alterações significativas na diversidade: H' = 2,84 nats indivíduo-1, J' = 0,73 em 2000; H' = 3,02 nats indivíduo-1, J' = 0,74 em 2008. Esses ambientes diferenciados parecem ser muito dinâmicos em sua florística, sem que a estrutura comunitária e a diversidade sejam afetadas. Mais estudos de dinâmica, por períodos mais longos, ainda são necessários para que se possa compreender o ambiente florestal inundável do Brasil Central com mais segurança, gerando informações que subsidiem ações prementes de conservação.

The Effects of the Breast Cancer Mammography Screening Programme in Women aged 40 to 84 years in Turku, Finland (1987-2009)

The objective of this thesis was to evaluate whether a more extensive mammography screening programme (TurkuMSP) conducted by the city of Turku, had an effect on breast cancer (BC) incidence, survival, or mortality in years 1987 to 2009. Despite the fact that some studies have suggested a 20 percent reduction in BC mortality due to mammography screening, there are findings of harm to subjects, which are claimed to negate the benefits of screening. Thus, the aims of this study are most pertinent. A total of 176 908 screening examinations were performed in 36 000 women aged 40−74 during the years 1987−1997. In all, 685 primary BCs were found in the screened women, either screen-detected (n=531) or during screening intervals (n=154). Survival and BC recurrence rate of women with screen-detected BC was compared to 184 women with clinical BCs detected among individuals who did not take part in the screening. The invitation interval, which may influence the outcome, was studied in the age group 40 to 49 by inviting those born in even calendar years annually for mammography screening and those born in odd years, triennially. In addition, BC incidence and mortality in the total female population of Turku aged 40 to 84 years was compared with the respective figures of Helsinki and the rest of Finland, both during the pre-screening era (1976-1986) and the screening era (1987-2009). The study was designed to compare women by age groups, because women aged 50 to 59 were generally screened in all of Finland, whereas only in Turku women aged 40 to 49 and 60 to 74 were screened in addition. Data regarding cancer recurrence were derived from the Finnish Cancer Registry and data on deaths were collected from Statistics Finland. In survival analyses, screened women with invasive BC had a significantly higher survival rate than the women with clinical BC. The survival benefit started to appear already during the first follow-up years and was evident in all age groups. A marginal survival extension was also seen in screened women when BC had spread to ipsilateral axillary nodes already at diagnosis. Recurrence-free survival rate after BC treatment was significantly more favorable among the screened women compared with women with BC found clinically. The screening invitation interval did not significantly influence BC mortality in the subset of women aged 40 to 49 years. There were no consistent differences in the changes of BC incidence between Turku and the comparison areas during the screening era. In Turku, the BC mortality incidence in women aged 55−69 years was significantly lower during the screening era (from 1987 to 1997) compared with the pre-screening era, whereas no such change was found in the city of Helsinki or Tampere. When comparing the changes in incidence-based BC mortality during years 1987 to 2009 in Turku to those of Helsinki and the rest of Finland, there was a suggestion of more than 20 percent lower mortality in Turku among oldest age group (75-84 years) compared with the reference residential areas, but the differences were not consistently significant. Interpretation of the study results should be made with caution because there were no random control groups, and on the other hand, the number of cases in subgroups was fairly low to yield definite conclusions. Also due to the many statistical analyses, some of the findings may be due to chance. The results are, however, suggestive for a decrease of BC mortality in the elderly age groups due to wide mammography screening. This finding needs confirmation in further studies before recommending an expansion of mammography screening to women up to the age of 74 years
