Simulation of coal preparation plants
SIMULATION, 1986Coal preparation is a process for removing physical impurities from coal. The process is carried out in large plants whose capa cities range from 500 to 20,000 tons of coal per day. There are about 500 such plants within the United States. A coal preparation plant simulator was developed under the sponsorship of the U.S.

Preparation of transgenic plants
1970Selectable marker genes are used in nearly all transformation procedures. They are required for efficient generation of transgenic plants, but serve no purpose once plants have been obtained that are homozygous for the transgene. On the contrary, their continued presence can pose technological problems, because it precludes retransformation (gene ...

Instrumentation for Coal Preparation Plants
IFAC Proceedings Volumes, 1980Abstract The paper presents the measuring devices used in Poland for monitoring of coal preparation processes with particular consideration of the problems of coal quality automatic control. There are discussed the operation and construction principles of radiometric ash meters and moisture meters used for continuous measurement as well as laboratory

Preparation of Nanocellulose From Plants
2023Plants contain the most abundant natural polymer cellulose in nature. Plants have a multilayered structure, made up of cells at the microscopic level. The main material of cells exists in the cell wall, mainly in the form of cellulose nanofilament-matrix composite structure, which plays a crucial role in the performance and function of plants ...

[Hepatoprotective effect of plant preparations].
Eksperimental'naia i klinicheskaia farmakologiia, 2002The hepatoprotector activity of original compositions of plant origin, containing beet and carrot juices, decoction of dog rose fruits, and extracts of corn silk, peppermint leaves, and common horsetail herbs was studied on an acute hepatitis model induced by tetrachloromethane.

Planting, Site Preparation and Maintenance
1986Methods for establishing tree plantations have undergone quite fundamental change in recent decades as a consequence of the application of the results of both applied and basic research. A careful evaluation has also been made of methods used and some changes made as a result of a number of reports from quite different parts of the world of a decline ...
