Accdg to Refs the USBurMines in cooperation with Sun Oil Co investigated the application of expl fracturing for stimulating natural gas recovery. Two tests con ducted in the shallow Buzzard Sand formation in Osage County,Oklahoma, demonstrated that desensitized NG can be safely loaded, displaced and detonated in hydraulically induced fractures both in open-hole intervals and thru casing perforations Refs l)W.D.Howell T.J.Clare, "Case... 

After more tests and the preparation of other batches of heparophosphatide, I went one morning to the door of Dr. Howell s office, and standing there (he was seated at his desk), I said Dr.

Schumacher, Howell, and Wfeber (1996) Wfeber and Johannes (1996). These are tenative specifications for 100% biodiesel and ate being evaluated by the American Society for Testing and Materials as of March 4, 1996. A considerable amount of experience exists in the United States with blends of 20% biodiesel and 80% diesel fuels. Although biodiesel can be used in this form, the use of blends over 20% biodiesel should be evaluated on a case-by-case basis until further etqje-rience is available. The GC method for glycerol is the Austrian update (Christiana Plane) of the U.S. Department of Agriculture method. 

Extracts of pure proanthocyanidins have been prepared using reversephase and adsorption chromatography, and their identity confirmed with 13C nuclear magnetic resonance imaging, ultraviolet spectroscopy, and chemical reagent tests (Howell and Vorsa, 1998). 

The most common tests are (1) Clotting time of whole blood-, (2) clotting time of whole blood collected and measured in silicone-, (3) prothrombin time Quick)—clotting time of recalcified plasma with added thromboplastin (tissue extract) (4) plasma time Howell)—clotting time of recalcified plasma ... 

Stability tests developed for petrodiesel fuels reportedly are not suitable for biodiesel or biodiesel blends with petrodiesel (Canakci et al., 1999 Stavinoha Howell, 1999 Westbrook Stavinoha, 2003), however, appropriate modification may render them useful. Another study (Bondioli et al., 2003) states that the petrodiesel method ASTM D4625 (Standard Test Method for Distillate Fuel Storage Stability at 43°C (110°F) is suitable but not fast.
