The significant effect of the addition very small proportions nanofibres and nano-particulates on physical mechanical properties solid materials has been long observed described. electrospun fibres liquid not so widely examined. In this paper, polyvinyl alcohol (PVOH), zein nanofibers in sunflower (Helianthus annuus) oil its viscosity was quantified. For a given amount material, trend increasin...

Aerosol transmitted COVID-19 virus (SARS-CoV-2) is infectious causing both symptomatic and asymptomatic infections. The viable transmission via air has occurred. Therefore, methods must be established to determine the viability of disinfect it in air, surfaces, on foodstuff. In this review article, we have discussed pattern spread bus, hospital, cruise ship. reducing eliminating infection house...

Chromatographic system for simultaneous determination of levodopa, biogenic amines, and methylxanthines in food has been developed. Chromatographic column and precolumn with octadecylsilane phase and simultaneously fluorescence and DAD detectors have been used. Gradient elution with acetate buffer (pH=4.66) with acetonitrile has been applied. Examination included levodopa, norepinephrine, dopam...

Shifting away from traditional approaches orientated towards the analysis of the benefits associated with brokerage, this paper provides valuable insights on the dynamics of this network position providing opportunities to innovate. Using fine grain micro data collected in a foodstuff Spanish cluster, the evolution of five different brokerage profiles is analysed in depth. Particularly, we obse...
