Antyceremonie : od "potęgi smaku" do rewolucji ("Niesmacznik" Natalii Usenko)
No full textThe article is an attempt to show the ritual of dining as a tool of oppression applied
to children. Literature aimed at children tries to help them overcome the trauma of eating
process by showing culinary experience as a social event, which is the beginning
of reflection on freedom, possibilities of making choices or building one’s own identity.
According to the author the collection of poems by Natalia Usenko serves that purpose

Atmospheric concentrations of organophosphate esters in Delhi, India.
No full textThe rise of organophosphate esters (OPEs) as ubiquitous global air pollutants is in part associated with their high-production volume, physical and chemical properties, and heavy use in consumer products, including many electronics. The current study investigates the composition and seasonal variability of atmospheric OPEs in Delhi, India. Atmospheric PM2.5 (particulate matter with an aerodynamic diameter ≤ 2.5 microns) samples were collected from April to November 2009 in downtown Delhi. PM2.5 samples were extracted using pressurized liquid extraction and the extracts were analyzed for twelve OPEs, including TPhP, using gas chromatography-mass spectrometry. The sum of atmospheric OPE concentrations ranged from 2.71 to 61.4 ng m^-3 abd were up ~600 times that of concentrations reported in the US. Findings from a study were similar to those reported from e-waste recycling areas in Pakistan, where TPhP was the dominant OPE. This may suggest that e-waste recycling is a major source of atmospheric OPEs in Delhi
Fate and transport of emerging contaminants across a dynamic urban landscape.
No full textTwo major classes of emerging contaminants (flame retardants/plasticizers and current-use pesticides (CUPs)) were measured across Houston, TX. Atmospheric particulate matter (PM) samples were taken at high spatial resolution in conjunction with NASA’s DISCOVER-AQ Houston campaign, a month-long, sampling intensive campaign in September 2013. Samples were taken at four ground-based sampling sites (300 filter-based PM samples) at least daily, improving temporal resolution, in both PM₂.₅ (PM less than 2.5 μm in aerodynamic diameter) and TSP (total suspended particulate) sample size fractions. Select samples collected during this campaign were analyzed for organophosphate esters (OPEs; emerging flame retardants/plasticizers) and CUPs (including mosquito adulticides). To analyze samples for these and other compounds of interest, a method first had to be developed for the simultaneous extraction of over 130 organic tracers (e.g., current- and historic-use pesticides, PCBs, OPEs, PBDEs, PAHs, alkanes, hopanes, and steranes). The extraction is carried out using pressurized liquid extraction, an automated technique, with extracts capable of being analyzed on multiple instruments to expand analysis capabilities. OPEs and CUPs (including mosquito adulticides) were examined for spatial and temporal heterogeneity, with large variability observed among urban, suburban, and industrial sampling sites, as well as day-to-day and diurnal differences. OPEs were also compared to bulk carbon measurements to improve understanding of atmospheric transport across the four sites. For mosquito adulticides, the oxidation of malathion was of particular interest. This oxidation not only appears to proceed faster than previous estimates from agricultural-based studies (hours compared to days), oxidation appears to occur during the night, due to reaction with either ozone or nitrate radicals. Determinations of atmospheric PM concentrations of emerging contaminants, specifically flame retardants and CUPs, lies at the interface of environmental and human health, as both classes of compounds have known benefits to humans, but also known toxicities. Additionally, spatial and temporal heterogeneity of these emerging contaminants in an urban area suggest that long-term sampling schemes (24 h samples taken on a 1-in-6 or 1-in-12 day sampling schedule) may not be representative of the day-to-day atmospheric PM concentrations present in these dynamic urban landscapes

ANALYSIS OF SOME INDICATORS CELLULAR AND HUMORAL IMMUNITY IN CHILDREN WITH BRONCHIAL ASTHMA
No full textIn children with atopic asthma were studied indexes of specific cellular and humoral immunity in the dynamics: when receiving to the clinic before discharge and after 3 months of remission. Changes in some immunological parameters are phase nature. In the period of intensifying of disease a lymphopenia that was expressed in the decline of amount of Т and B of cells were marked. Except it, the disbalance of immunoregulatory subpopulations of T-cell was marked, that showed up in the decline of Т-helper, and in the increase of T-suppressor-cell for children that are ill atopic bronchial asthma. Disimmunoglobulinaemia consisted in the decline of concentration of Ig A, increase of concentration of Ig M and Ig G. The period of clinical recovery was accompanied by normalization of immune status of minor children. Not fully recovered rate of cellular immunity link
