We have developed a one-point microcapsule agglutination test (MCAT) for the serodiagnosis of leptospirosis. The MCAT kit was evaluated for use in humans by six WHO Collaborating Centres for Reference and Research on Leptospirosis. The laboratories classified their serum samples on the basis of the microscopic agglutination test (MAT) and the following screening tests: enzyme-linked immunosorbe...

Two new antigenic acidic polysaccharides, Vi-P and Vi-C, were isolated from the microcapsule of Salmonella typhi by a very mild procedure. The antigens were purified to serological homogeneity, and it was found that each of them shares with Vi antigen one of its two serological determinants (a different one in each case). One of the antigens Vi-C, was also isolated from Escherichia coli B, whic...

This paper is a continuation of previously published on this issue that studied the microencapsulation calcium nitrate in urea-formaldehyde shell using Aerosol OT (AOT) hexane solution. The aim to determine quantity AOT optimizes microcapsule distribution, diameter, and thickness. Different quantities AOT, namely 0.25 g, 0.50 1.5 2.5 g were dissolved 180 solution prepare continuous phase. A Sca...

The application of thermal energy storage (TES) is an effective way of improving the power load regulation capability of combined heat and power (CHP) generating units. In this paper, a theoretical investigation on the thermal energy storage system of a CHP unit that employs the microencapsulated phase change material slurry (MPCMS) as the working fluid is carried out. The results indicate that...

The density of microcapsules was compared on 'Golden Delicious' mature and immature foliage, fruit, and 1-yr-old limbs after dip treatments with Phase III oriental fruit moth, Grapholita molesta (Busck), microencapsulated pheromone. Microcapsules were counted with a dissecting microscope at 50x magnification after apple tissues were treated with a two-step dye staining process to increase the v...
