Polymer (XAD7HP)/Ti4+ nanocomposites were prepared through the swelling of polymer in titanium (IV) ethoxide as a titanium dioxide precursor. The nanocomposite beads exhibit relatively high porosity different than the porosity of the initial polymer. Thermal treatment of composite particles up to 200 °C in vacuum causes the change of their internal structure. At higher temperature, the componen...

The collagen structure of isolated and in situ liver granuloma from Swiss Webster mice infected with Schistosoma mansoni was sequentially and three-dimensionally analyzed during different times of infection (early acute, acute, transitional acute-chronic, and chronic phases) by laser scanning confocal microscopy and electron scanning variable vacuum microscopy. The initial granuloma structure i...

The present study aimed to evaluate the lipid content and oxidation of fallow deer (FD), wild boar (WB), pig meat (PM) at −18 °C for a 360-day storage period. lowest fat was observed in thigh (TM) FD (2.53%; p ˂ 0.05). ratio polyunsaturated/saturated fatty acids (PUFA/SFA), n-6/n-3, hypocholesterolemic/hypercholesterolemic index (h/H), nutritional quality indexes were calculated. PUFA/SFA each ...

background the vacuum assisted closure (vac) therapy has revolutionized the modern wound care. we developed a new concept of ‘vac at home’ in order to decrease the hospital cost. methods the study was conducted in a private hospital from january 2009 to december 2010. only those patients were included among whom the wounds were not complicated by concomitant injury and the patients were otherwi...

O₂ sensors were used to non-destructively monitor O₂ levels in commercially packed pre-cooked, convenience modified atmosphere packaging (MAP) foods. A substantial level of O₂ (>15%) was present in packs resulting in a shorter than expected shelf-life, where the primary spoilage mechanism was found to be mould. Various combinations of vacuum (0-0.6 MPa) and gas flush (0.02-0.03 MPa) (30% CO₂/70...

We investigate the topological structure of the vacuum in SU(3) lattice gauge theory. We use under-relaxed cooling to remove the high-frequency fluctuations and a variety of “filters” to identify the topological charges in the resulting smoothened field configurations. We find a densely packed vacuum with an average instanton size, in the continuum limit, of ρ̄ ∼ 0.5 fm. The density at large ρ d...
