The Strength of the Japanese Agar-agar Gel

Behavior of the Serum proteins in starch-agar-gel electrophoresis

The Introduction of Agar-agar into Bacteriology.

Among fundamental developments in bacteriology the elaboration of solid culture substrates will always hold first place. With the introduction of a method for isolating micro6rganisms and growing them in pure culture, bacteriologists possessed the means for studying what Ferdinand Cohn (1872) called "Die kleinsten lebenden Wesen." Credit for the discovery of the solid medium technique is common...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

Completely Adjustable Multipurpose Agar Gel Cutter.

Recent progress in the study of antigen-antibody reactions of biologicals in agar gel demands improvement of existing gel-cutting devices. For an ideal comparison of two or more antigenic preparations against an antiserum, it is necessary to obtain a critical distance between the ( antigen and antibody cups and to obtain a partial or complete identity of precipitinogen in adjacent cups. However...

A method for the electrophoresis of colicines in agar gel.

The design, construction, and use of an apparatus for the electrophoresis of colicines in agar gel is described, as are some preliminary experiments with it. The possibilities of this method in typing strains of colicinogenic organisms and for the study of colicines are also discussed. In 1953, Ludford and Lederer, using a simple apparatus, demonstrated that substances known as colicines consis...
