the investigations were carried out in 2007 on the fruit of 7 native early-ripening apple cultivars grown in karaj climatic conditions, harvested in two phenological stages of maturity and ripenning. the harvested samples were stored at (0 ± 0.5) c and (85 ± 5) % of humidity. the measured sensorial traits consisted in: aroma, flavor, sweetness, flesh quality and general acceptability achieved ...

Cold storage is considered the most effective method for prolonging fresh produce storage. However, subtropical fruit is sensitive to cold. Symptoms of chilling injury (CI) in mango include red and black spots that start from discolored lenticels and develop into pitting. The response of 'Keitt' mango fruit to chilling stress was monitored by transcriptomic, physiological, and microscopic analy...

Citrated platelet-rich plasma (PAP) was kept at cold temperatures or room temperature. After 4 hr or more at these temperatures, the PRPs were warmed 1 hr at 37#{176}C. This prevents the spontaneous aggregation seen in chilled PRP that is stirred immediately after warming. Platelet aggregation in response to connective tissue (CT), epinephrine, and adenosine diphosphate (ADP) was considerably g...

grape is used in large amounts and different types (fresh, raisin, vinegar, molasses, juice, unriped grape and etc). remarkable amount also are preserved in stores and cold-rooms to be supplied out of season, that causes  quality and weight decrease. this research was conducted to study different factors which affect the grape shelf-life. obtaining more information about optimum conditions and ...

Conventional cold storage and cryopreservation methods for hops (Humulus lupulus L.) are available but, to our knowledge, the genetic and epigenetic stability of the recovered plants have not been tested. This study analyzed 51 accessions of hop using the molecular techniques, Random Amplified DNA Polymorphism (RAPD) and Amplified Fragment Length Polymorphism (AFLP), revealing no genetic variat...

Optimal storage conditions to retain ribulose 1, 5-bisphosphate carboxylase/oxygenase (Rubisco) activity were investigated. The soluble spinach (Spinacia oleracea) enzyme was pretreated with its activators, Mg(2+) and HCO(3) (-), and then stored for up to 30 days at 4 or -18 degrees C or in liquid N(2). Cold inactivation and conformational changes were suggested to be involved during Rubisco st...

A major expenditure in vector biology laboratories is the rearing of mosquitoes. Most mosquito colonies require substantial effort to maintain, including frequent bloodmeals for optimal performance. Successful cryopreservation of mosquitoes continues to be elusive. Although using diapause as a storage mechanism is an option for mosquito preservation, several obstacles include the lack of a well...

Cloud providers and companies running large-scale data centers offer near-line, cold, and archival data storage, which trade access latency and throughput performance for cost. These often require physical rack-scale storage designs, e.g. Facebook/Open Compute Project (OCP) Cold Storage or Pelican, which co-design the hardware, mechanics, power, cooling and software to minimize costs to support...

The regulatory metabolite, fructose 2,6-bisphosphate (Fru 2,6-P(2)) was found in green pepper (Capsicum annuum L.). The Fru 2,6-P(2) level was found to: (a) rise rapidly in response to heat; (b) drop rapidly, followed by recovery, in response to cold storage of fruit and, (c) oscillate during cold storage of fruit. The possible existence of a relationship between chilling injury and Fru 2,6-P(2...

Phase change materials (PCM) are thermal storage materials with a high storage density for small temperature range applications. One such application is the storage of natural cold of the night to use during daytime, called “free cooling”. Very high energy efficiency can be reached as the cold has not to be generated. Those systems are especially interesting for lightweight buildings, which hea...
