The sharpening of microtome knives.

The regular production of a satisfactory edge on a microtome knife for the cutting of sections as thin as 2 u, which are free from scores and other blemishes, is a serious technical problem in histological laboratories. Eyen when a good edge is produced on a knife, its life is generally limited because contact with any hard material in the specimen may damage the delicate edge, causing it to sc...

Physicochemical Analysis of Margarine, Butter and Butter Oil Samples of Iran’s Markets

Butter, margarine and butter oil are three products which consume daily by Iranian’scommunity. Detection of type and existence of synthetic antioxidants (SAs) quantities in the margarine, butter and butter oil samples is so important in point of view of the safety.
