Net accumulation rates derived from ice core stable isotope records of Pío XI glacier, Southern Patagonia Icefield

Pío XI, the largest glacier of the Southern Patagonia Icefield, reached its neoglacial maximum extent in 1994 and is one of the few glaciers in that area which is not retreating. In view of the recent warming it is important to understand glacier responses to climate changes. Due to its remoteness and the harsh conditions in Patagonia, no systematic mass balance studies have been performed. In this study we derived net accumulation rates for the period 2000–2006 from a 50 m (33.2 4 m weq) ice core collected in the accumulation area of Pío XI (2600 m a.s.l., 49°16'40"S, 73°21'14"W). Borehole temperatures indicate near temperate ice, but the average melt percent is only 16 ± 14%. Records of stable isotopes are well preserved and were used for identification of annual layers. Net accumulation rates range from 3.4–7.1 water equivalent (m weq) with an average of 5.8 m weq, comparable to precipitation amounts at the Chilean coast, but not as high as expected for the Icefield. Ice core stable isotope data correlate well with upper air temperatures and may be used as temperature proxy.

Patient-Oriented SCORAD (PO-SCORAD): a new self-assessment scale in atopic dermatitis validated in Europe

BACKGROund: Patient-oriented medicine is an emerging concept, encouraged by the World Health Organization, to greater involvement of the patient in the management of chronic diseases. The Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD) index is a self-assessment score allowing the patient to comprehensively evaluate the actual course of atopic dermatitis (AD), using subjective and objective criteria derived mainly from the SCORAD, a validated AD severity clinical assessment tool.

Polonofilizm i polskość wśród czeskich emancypantek w drugiej połowie XIX wieku: przykład Karoliny Světlej

The awakening of national consciousness went hand in hand in Bohemia with an anxiety about national disappearance. In this context, the recourse to Pan-Slavism was for the Czechs a way to encourage themselves through the idea of belonging to a great Slavic world, while the Slavic Congress organized in Prague in 1848 was an attempt to realize this ideal. The Congress was a failure from the political point of view, but it did have some socio-cultural repercussions: notably, it served as a pretext for the advancement of women's issues in Bohemia. It is indeed in the wake of the Congress that Honorata z Wiśniowskich Zapová, a Polish women settled in Prague after her marriage to a Czech intellectual, founded, under the guise of collaboration between all Slavic women, the first women's association, as well as a (very short-lived) Czech-Polish institute, where Czech, as well as Polish girls, could get a quality education in their mother tongue. Honorata was undoubtedly the source of the polonophilia wind that seemed to blow over the Czech emancipation movement in the second half of the nineteenth century. In particular, Karolina Světlá showed in her Memoirs a great recognition for Honorata's efforts in matters of emancipation and education, and explicitly took up the challenge launched by the latter in founding another women's association and in inaugurating a school for underprivileged girls. But the tribute Světlá paid to Honorata is even more evident in her literary work, where Poland and the Polish woman (who often wears Honorata's features) play a significant role (see for example her short novel Sisters or her story A Few Days in the Life of a Prague Dandy). Světlá was probably the Czech feminist writer who, in her activities and in her work, relied most strongly on the Polish woman as a model for the Czech woman. However, she wasn't alone. In general, it was a characteristic of the Czech feminist movement of the second half of the nineteenth century to have recourse to the Polish woman and to Poland as a landmark for comparison and as a goal to be achieved.

Occurrence, gas/particle partitioning and carcinogenic risk of polycyclic aromatic hydrocarbons and their oxygen and nitrogen containing derivatives in Xi'an, central China

29 parent- and alkyl-polycyclic aromatic hydrocarbons (PAHs), 15 oxygenated-PAHs (OPAHs), 11 nitrated-PAHs (NPAHs) and 4 azaarenes (AZAs) in both the gaseous and particulate phases, as well as the particulate-bound carbon fractions (organic carbon, elemental carbon, char, and soot) in ambient air sampled in March and September 2012 from an urban site in Xi'an, central China were extracted and analyzed. The average concentrations (gaseous+particulate) of 29PAHs, 15OPAHs, 11NPAHs and 4AZAs were 1267.0±307.5, 113.8±46.1, 11.8±4.8 and 26.5±11.8ngm(-3) in March and 784.7±165.1, 67.2±9.8, 9.0±1.5 and 21.6±5.1ngm(-3) in September, respectively. Concentrations of 29PAHs, 15OPAHs and 11NPAHs in particulates were significantly correlated with those of the carbon fractions (OC, EC, char and soot). Both absorption into organic matter in particles and adsorption onto the surface of particles were important for PAHs and OPAHs in both sampling periods, with more absorption occurring in September, while absorption was always the most important process for NPAHs. The total carcinogenic risk of PAHs plus the NPAHs was higher in March. Gaseous compounds, which were not considered in most previous studies, contributed 29 to 44% of the total health risk in March and September, respectively.
