The results showed that all the AgNO3 (20-40 wt %) doped PVA films presented an exothermic peak at 182 degrees C. And the temperature of exothermic peak kept constant for various contents of AgNO3. Meanwhile, the phase composition of the films was greatly affected by the heat treatment temperature. Ag particles were generated during the heat treatment process, and the content of Ag particles increased with increasing the temperature. The YM155 research buy resistivity of

PVA/AgNO3 films decreased with increasing the temperature. And a sharp decrease appeared at 155-165 degrees C due to the generation and contact of a mass of Ag particles at this temperature. The thermal-electrical results suggested the applicability of these materials in temperature sensor, for example, critical temperature resistor thermistor.

“Papular purpuric gloves and socks syndrome (PPGSS) is a self-limited, often febrile illness with symmetric edema and erythema of the hands and feet; papular, petechial, and purpuric acral dermatosis; and mucosal lesions in children

and young adults. Most of the cases of PPGSS have been reported to be caused by parvovirus B19 and other viruses. This study describes a case resulting from Mycoplasma pneumoniae infection in an adolescent male and

reviews the literature.”
“This study provides a new understanding of cellulose oxygen (delta O-18(cel))isotopic variability in various plant macrofossils, particularly Sphagnum, derived from an similar to 9200 year succession of Holocene peat in Mer Bleue Bog, Ottawa, Apoptosis inhibitor Ontario, Canada. The variation of delta O-18(cel) isotopic composition, commonly used as a proxy of paleotemperature and paleoprecipitation, was compared between (1) Sphagnum and other plant macrofossils down core and (2) Sphagnum species within and between samples.\n\nThe most common Sphagnum species encountered was Sphagnum magellanicum von Bridel, 1798 with lesser amounts of Sphagnum capillifolium (Breutel) Steudel, 1824, Sphagnum fuscum Klinggraff, 1872 and Sphagnum angustifolium Jensen, 1896. There is a statistically significant offset in delta O-18(cel) isotopic values (mean offset: 1.6 parts per thousand, standard deviation = 3.2%, n = 19) obtained from Sphagnum in comparison with values obtained from other plant macrofossils, particularly rhizomes. The delta O-18(cel) isotopic offset (mean offset: 0.1 parts per thousand, standard deviation = 1.0 parts per thousand, n = 11) between Sphagnum specimens from the same core horizons, irrespective of the species analyzed, was statistically insignificant at > 95%.
