Small–scale Mechanical Carrot Washer for Research Sample Preparation

Carrot samples from field research studies of irrigation, fertility, and variety trials must be cleaned prior to weighing and grading. Soil and other foreign materials must be removed, especially for medium– and heavy–textured soils in which a preharvest irrigation is used to loosen the soil prior to hand harvesting. The objective of this project was to develop a low–cost mechanical carrot wash...

Roughness Model for Adhesion Testing of Pharmaceutical Coating Materials

Objective Roughness is the main parameter in interlocking bonding mechanism. Yet there is no model designed to evaluate the effect of surface roughness on adhesion of coating materials in pharmaceutical sciences. Materials and Methods In this study polymethyl metacrylate spherical beads with different sizes were poured into 10 mm mold, then it was pressed by hand screw and finally heated to 141...

Nondestructive Testing of Mechanical Parameters for Wood-based Materials

This article describes the national and international history, present situation and developing tendency in the research on nondestructive testing of mechanical parameters of Wood-based materials. It stressfully introduces foreign contributions in the field in order to provide some useful references to the researchers.

Preparation of radioactive iodocasein.

We have recently prepared iodocasein containing radioactive iodine (1’31) for use in studies, to be described in detail elsewhere, on the metabolism of calorigenic substances in human beings. The procedure followed was, in general, that of Reineke and Turner (1,2) except for modifications necessitated by the incorporation and handling of Pal. These modifications shorten the procedure somewhat a...
