The lower the friability
rate, the more resistant the briquette.
The study confirmed that brands of glibenclamide tablets complied with the official specification for hardness, friability
, assay, and disintegration.
indices ([F.sub.Y] and [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) were [log.sub.10]- transformed to obtain homogeneity of the variances.
Hardness varied from 37.69 [+ or -] 4.08 to 48.73 [+ or -] 5.62N, and the friability
was less than 1%, indicating that the tablets had sufficient mechanical integrity and would be able to withstand packaging and carrying.
The average friability
and hardness of the formulations were in USP acceptable range and fulfilling the requirements of dosage uniformity (table 3).
 was determined from the weight loss of the sample after friction.
Active Energy said that the finished fuel, which can be delivered in a range of different compacted formats (pellets, granules, briquettes or bales), contains similar thermal and friability
characteristics to coal, enabling it to immediately be used in existing coal-fired power stations without costly retro-fitting, reconstruction or output losses.
and wet tensile strength tests are currently used in the industry, the modified cone jolt and thermal erosion tests may allow metalcasters to improve the control of their green sand systems, in a more timely manner.
In our case the lesion replaced almost entirely the testicular parenchyma, showing a variable appearance, friability
, cavitations in a reticular pattern and soft brown hemorrhagic material and fibrin without evidence of neoplasia.
At end point, clinical vaginal examinations demonstrated improvements in all domains of tissue integrity such as pallor, petechiae, friability
, and vaginal mucosal dryness, compared to placebo indicating a restorative tissue effect along with symptom relief.
