Several pBR DNA plasmid storage conditions were evaluated in this study, including the storage form (liquid or dried on 3M paper), the buffer used to dissolve the plasmid, and temperature. Storage in the liquid form resulted in increased colony formation compared to DNA dried on paper, which is a more convenient and often preferred method for shipping plasmids. The TE buffer was superior to aut...

cell formation problem mainly address how machines should be grouped and parts be processed in cells. in dynamic environments, product mix and demand change in each period of the planning horizon. incorporating such assumption in the model increases flexibility of the system to meet customer’s requirements. in this model, to ensure the reliability of the system in presence of unreliable machine...

With continuing improvements in both the price and the capacity, flash memory-based storage devices are becoming a viable solution for satisfying high-performance storage demands of desktop systems as well as mobile embedded systems. Because of the erase-before-write characteristic of flash memory, a flash memorybased storage system requires a garbage collection, which often introduces large pe...

B iopharmaceutical processes are operated in aqueous systems using large quantities of WFI or Purified Water (PW). In the upstream process (USP), WFI is required for media preparation and feed solutions. In the downstream process (DSP), large quantities of PW or WFI are required for buffers, with buffer preparation, buffer storage, and distribution systems representing a significant portion of ...

Fast reaction times and high discharge rates make steam accumulators a promising option for compensation of fast transients in insolation for solarthermal systems using steam as working medium. Using the volume of components like separator drums or heat exchangers for storage of pressurized hot water is a cost-effective approach to integrate buffer storage capacity. While the basic steam accumu...

This paper compared and analyzed efficiency of each storage medium, by changing the size of data buffer caching in a memory, after connecting DBMS with a storage medium. According to the result of the test, both performances of storage media increased, as the buffer size was greatly reduced. Seeing that D-SSD's performance and HDD's performance changed from above 1GB and 2GB, respectively, it i...
