physical properties are often required for designing post harvest handling and processing equipment for agricultural products. persimmon (khormandy cultivar) is rich in vitamin a, calcium, potassium, tannic acid and antioxidant phenolic compounds. in this study changes in the physical properties of persimmon fruit during storage were studied. properties such as fruit dimensions, mass, geometric...

interaction of menthol with polyethylene terephthalate bottles during storage time was tested at three different temperatures. menthol is a mint flavor agent added to yogurt drinks in iran and is considered as a factor affecting consumer acceptance. absorption of menthol to packaging material could cause a loss of quality in the final product due to diminished flavor intensity. tests were done ...
A systematic way of extending a general fixed-stepsize multistep formula to a minimum storage variable-stepsize formula has been discovered that encompasses fixed-coefficient (interpolatory), variable-coefficient (variable step), and fixed leading coefficient as special cases. In particular, it is shown that the " interpolatory" stepsize changing technique of Nordsieck leads to a truly variable...
This paper presents experimental studies on thermal stratification in chilled-water storage systems. A fibreglass storage tank in static and dynamic modes of operation is used. The parameters varied are aspect ratio, flow rates, initial temperature difference and thickness of insulation. Emphasis is given to the effects of mixing at the inlet, leading to the definition of the mixing coefficient...
a methodology of ecological risk assessment for the terrestrial ecosystem under chronicradioactive pollution of a biotope near a regional radioactive waste storage has been developed in terms of thecritical environmental loads analyzed. it consists of five stages: determination of effect indicators and assessmentof their values; establishment of reference species and indices; assessment and ana...
The dynamics of a reaction-diffusion system for two species of microorganism in an unstirred chemostat with internal storage is studied. It is shown that the diffusion coefficient is a key parameter of determining the asymptotic dynamics, and there exists a threshold diffusion coefficient above which both species become extinct. On the other hand, for diffusion coefficient below the threshold, ...
most consumers prefer natural coatings to the chemical ones to act as an enhancement of storage quality of fruits. in this research, quality of thomson oranges coated with chitosan-clay nano composite edible coating plus fungicide-wax chemical coating was compared with a non-coated sample during storage for a period of 3 months through a factorial design (3×4). orange samples were kept in a col...
