Effect of nano composite films to prolong the shelf life of Iranian beluga caviar was investigated at different concentrations of silver nanoparticles. In this study 38 caviar packs each containing 5 g of caviar were divided into 6 treatments with 3 replicates. The concentrations of 1000, 2000, 3000, 4000, 5000 and 6000 ppm of nanoparticles as well as a nano free pack as control were used. The ...

wound care management is a continuous challenging task for researchers and tissue engineers. skin substitutes (synthetic and natural) have been introduced as emergency replacements/grafts to the damaged skin and a number of problems such as infection, graft rejection, inadequate healing, short shelf life etc. have reduced their clinical importance as being the ideal skin substitutes. a number o...

Fodd Scientists and technologists have long been searching for fat su bstitutes, i.e. compounds with physical and organoleptic properties similar to conventional dietary fats and oils but with as few calories as possible. After many years of persistant efforts, they have recently achieved considerable sussess in this field. Since a diet high in fat and cholesterol is regarded as an important fa...

skin grafting always has been considered a challenging task for the researchers and tissue engineers from its first introduction in 1871 by reverdin. skin substitutes, composed of degradable synthetic or biological components, are being considered as emergency replacements/grafts to the damaged skin. a number of technical developments in this filed have led to development of several skin substi...

This study provides a novel framework for analysing systematic tail risk transmission mechanisms by combining the Conditional Autoregressive Value-at-Risk (CAViaR) model with recently developed Time-Varying Parameter Vector (TVP-VAR) based connectedness approach. We estimate dynamic spillovers across two crude oil (Brent and WTI) four refined petroleum product (gasoline, heating oil, jet fuel p...
