A method of preserving a harvested cultivated food can include applying a preservative composition onto a cultivated food. The preservative composition can include a folate substance or hydrogel having the folate substance in a carrier. The carrier and/or hydrogel may facilitate application of the folate to the cultivated food and may contribute to the improvement of preservation of the cultivated food post-harvest. A container can be configured for protecting harvested cultivated food by having a chamber with a preservative composition located in the container. A substrate can include a preservative composition located on the substrate, which can be applied to a cultivated food to increase preservation.

A food preservation system can include a gas (e.g., oxygen) permeable package having at least one oxygen permeable member defining a package chamber therein, and a silverized biomass in the package chamber of the oxygen permeable package. Another food preservation system can include a container having an internal chamber, and an oxygen permeable divider located in the internal chamber so as to divide the internal chamber into a first chamber and a second chamber. The first chamber can being configured for receiving food therein, and a silverized biomass is located in the second chamber. A method of preserving food can include retaining a food in a container that includes silverized biomass such that the food does not contact the silverized biomass. The silverized biomass can have a combination of silver and biomass.

A method of preserving a harvested cultivated food can include applying a preservative composition onto a cultivated food. The preservative composition can include an amino acid, peptide having the amino acid or protein having the amino acid. The amino acid or peptide or protein having the amino acid can be associated with a water soluble substance. The water soluble substance may facilitate application of the amino acid to the cultivated food and may contribute to the improvement of preservation of the cultivated food post-harvest. A container can be configured for protecting harvested cultivated food by having a chamber with a preservative composition located the container. A substrate can include a preservative composition located on the substrate, which can be applied to a cultivated food to increase preservation.

In this paper an integrated production-inventory model is presented for supplier, manufacturer and retailer supply chain, considering perfect and imperfect quality items. This model considers the impact of business strategies such as optimal order size of raw materials, production rate and unit production cost, and idle times in different sectors on collaborating marketing system. The model can be used in industries like textile and footwear, chemical, food, etc. An analytical method is employed to optimize the production rate and raw material order size for maximum expected average profit. An example is illustrated to study the behavior and application of the model. © 2010 Elsevier B.V. All rights reserved.

By late 18th or early 19th century, albino rats became the most commonly used experimental animals in numerous biomedical researches, as they have been recognized as the preeminent model mammalian system. But, the precise correlation between age of laboratory rats and human is still a subject of debate. A number of studies have tried to detect these correlations in various ways, But, have not successfully provided any proper association. Thus, the current review attempts to compare rat and human age at different phases of their life. The overall findings indicate that rats grow rapidly during their childhood and become sexually mature at about the sixth week, but attain social maturity 5-6 months later. In adulthood, every day of the animal is approximately equivalent to 34.8 human days (i.e., one rat month is comparable to three human years). Numerous researchers performed experimental investigations in albino rats and estimated, in general, while considering their entire life span, that a human month resembles every-day life of a laboratory rat. These differences signify the variations in their anatomy, physiology and developmental processes, which must be taken into consideration while analyzing the results or selecting the dose of any research in rats when age is a crucial factor.
