Bone marrow transplant (BMT) is an extraordinarily rapidly growing field, and the number of transplants in the U. S. is expected to grow from a current rate of 15,000 per year to over 100,000 per year by 1995. This rapid expansion is due to the diversity in the types of bone marrow transplantation procedures and the number of clinical procedures that can be benefitted by a BMT. Major limiting fact ...

In vitro expansion of hematopoietic cells finds many applications in the clinic. This technique hasexpanding CD34+ cells for transplantation/re infusion, although most of the technology has consistedcultures in which there is variable CFUGM expansions and failure to maintain LTC IC (long term cultuThe Investigators have found that perfusion cultures of bone marrow mononuclear cells result in expaC ...

As the ability to communicate with the health care system becomes more important, there isa risk that minority populations, particularly non-English speaking and undeserved persons, will fallfurther behind in the level of care they receive. We are currently developing a general healthcare planfor its member companies, expected to begin in April 1994, and to be fully insured and provided inpartners ...

An effective process for recycling plastics and composites used in aircraft does not currently exist. As a result, scrap and used materials are disposed of in landfills. A chemical recycling process is proposed that will allow the components of these waste materials to be converted to valuable hydrocarbons, fillers and fibers that can then be reused or sold. The proposed chemical recycling process ...

A novel tertiary recycling process is proposed for investigation as an economical means for reclaiming scrap aircraft transparency materials. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200 C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Met ...

Cured aircraft composite materials present a particularly difficult challenge for recycling technology. Those materials have mostly thermosetting epoxy matrices and occur in intimate association with metals, paints, and coatings. Current techniques for recycling thermoset composites, mostly for automotive sheet molding compounds (SMC), involve pulverizing the material for use as fillers. Th ...

A novel tertiary recycling process is proposed for investigation as an economical means for recycling shipboard plastic waste. Early development work has shown that this process can convert a wide variety of polymers and composites into low molecular weight hydrocarbons at temperatures below 200'C. The hydrocarbons produced can then be reused as chemicals, fuels, or monomers. Metal, glass, and fil ...
