Refrigerated storage cells

Air Dehumidification Results of Demonstration Tests with Refrigerated Storage Cells 505... 

Specifically, the demonstrations have been focused upon the dehumidification of air in refrigerated trucks at 5 °C and in intermediate cells of refrigerated storage rooms at T= 15 °C.

Hydrogen-storage alloys (18,19) are commercially available from several companies in the United States, Japan, and Europe. A commercial use has been developed in rechargeable nickel—metal hydride batteries which are superior to nickel—cadmium batteries by virtue of improved capacity and elimination of the toxic metal cadmium (see BATTERIES, SECONDARYCELLS-ALKALINe). Other uses are expected to develop in nonpolluting internal combustion engines and fuel cells (qv), heat pumps and refrigerators, and electric utility peak-load shaving. 

In addition, the CBER controls the approval of human tissue for transplantation, blood and blood products, and devices related to blood products. These devices include automated cell separators, empty plastic containers, and blood storage refrigerators and freezers. 

A number of advantages associated with live vaccines are that 1) they are cheap to produce because the inoculum dose is relatively less 2) they require fewer inoculations 3) they do not require adjuvants 4) they elicit both humoral and cell-mediated immune responses and 5) they can be inoculated by the natural route of infection. Some of the disadvantages associated with live vaccines are that 1) they are usually less stable than inactivated vaccines and may require refrigeration for storage 2) some of these vaccines under certain situations may revert to virulent form in the host and thereby lead to clinical disease 3) they may not be recommended for immunosuppressed, immature, older, or pregnant hosts 4) they may have a low level of residual virulence and 5) they may be contaminated with other adventitious organisms.
