    The problem of disabilities is growing all over the world. Nevertheless, some progress has been made since the year 1981 was proclaimed International Year of Disabled Persons. In 2001 people living with disabilities accounted ...
  • Cowan, Donald A. (Elsevier, 2004)
    The newly isolated hyperthermophilic archaeal strain 121 grows slowly at 121 8C and even survives short periods at 130 8C. This is another organism that grows best at temperatures well in excess of 100 8C! We should not ...
