six different composite packaging materials were tested with the trades’ practice of polythene bags in storing smoked catfish for a period of six months. the thickness of the packaging materials ranges from 0.23 to 046 mm with water and oil absorption rates of the packaging materials varies from 0.23 to 10.00 and 0.28 to 10.857 glcm2/mm respectively. the impact resistance weight also varies fro...

plastics are well-established for convenient and safe packaging and distribution of food and feed goods. at present, this special sector of the plastic market displays remarkably increasing quantities of its annual production. caused by the ongoing limitation and strongly fluctuating prices of fossil feedstocks, classically used for plastic production, there is an evident trend to switch toward...

Adenovirus (Ad) type 5 DNA packaging is initiated in a polar fashion from the left end of the genome. The packaging process is dependent upon the cis-acting packaging domain located between nucleotides 194 and 380. Seven A/T-rich repeats have been identified within this domain that direct packaging. A1, A2, A5, and A6 are the most important repeats functionally and share a bipartite sequence mo...

Modified atmosphere packaging (MAP) has become a popular method for packaging foods as it can extend the shelf life of food with minimal quality defect. Oxygen, nitrogen and carbon dioxide are the common gases used in MAP, Oxygen and carbon dioxide inclusive as only these two gaseous have the preservative effects on the packed food product. Their effect on microbial changes of any food product ...

We propose a simple model for the kinetics of packaging of viral DNA into a capsid against an external force trying to prevent it. The model leads to a Butler-Volmer-type dependence of the rate of packaging on the pulling force F.

Modified atmosphere packaging (MAP), including vacuum packaging, is a well-known technique used to prolong the shelf life of perishable food products. By eliminating or replacing the air surrounding a packed food product, various deteriorative processes that occur in food can be restricted mostly by reducing O2-concentrations and increasing CO2-concentrations. As it is important to maintain the...

saffron is a strategic exporting crop in our country and iran is known as the greatest producer and exporter of it in the world. deficient packaging systems can be the most common reasons of the decline in the iran's share in exporting saffron. appling the modern methods of packaging such as hurdle technology can greatly maintain the quality of saffron. despite developments in saffron packaging...

The human immunodeficiency virus type 1 (HIV-1) Vif protein plays a critical role in the production of infectious virions. Previous studies have demonstrated the presence of small amounts of Vif in virus particles. However, Vif packaging was assumed to be nonspecific, and its functional significance has been questioned. We now report that packaging of Vif is dependent on the packaging of viral ...
