Integration of Biological and Chemical Control: Specifications for Chemical Control

Bulletin of the Entomological Society of America, 1962
About 20 years ago economic entomology entered a highly productive period which was highlighted by the development of the synthetic organic insecticides, beginning, of course, when the insecticidal activity of DDT and BHC was discovered. Since that time the agricultural entomologist has been confronted with literally hundreds of new insecticides to be ...

Analytical Chemical Control of Phthalates in Toys:Analytical Chemical Control of Chemical Substances and Products

2001
The content of phthalates in toys and other articles for children up to 3 years of age is regulated by the Statutory Order of Danish Ministry of Environment and Energy, No. 151 of 15th March 1999. In the present investigation, 20 products (toys and other articles for children up to 3 years of age) were analysed for the content of phthalates on the ...

Controlling Chemical Reactivity with Antibodies

Science, 1993
The remarkable specificity of an antibody molecule has been used to accomplish highly selective functional group transformations not attainable by current chemical methods. An antibody raised against an amine-oxide hapten catalyzes the reduction of a diketone to a hydroxyketone with greater than 75:1 regioselectivity for one of two nearly equivalent ...

Chemical Control System of Epigenetics

The Chemical Record, 2018
Abstract Epigenetics represents the inheritable changes to the chemical control system governing the gene expression with no ensuing changes to the underlying DNA sequence. Environment‐mediated modification of the natural epigenetic interactions can perturb the cellular homeostasis and drive cells to a diseased state by switching ...

Adaptive Control in Chemical Industry

IFAC Proceedings Volumes, 1985
Many chemical plants have to be controlled such that their responses are within given tolerances under various operating conditions including variation in plant parameters and disturbances. It is therefore desirable to have adaptive controllers which can compensate for changes in process parameters due to varying working conditions or initial ...

Chemical control of feeding behavior

Comparative Biochemistry and Physiology Part A: Physiology, 1971
Abstract 1. 1. Chemical control of some aspects of feeding behavior is of widespread occurrence. 2. 2. A new classification of chemical effectors of feeding behavior is proposed. 3. 3. Specific chemical effectors of feeding behavior in many species are discussed. 4. 4.

Biomimetic Control of Chemical Selectivity

Accounts of Chemical Research, 1980
Enzyme mimics and artificial enzymes have been designed to imitate several different aspects of enzyme catalysis. For instance, mimics have been constructed to imitate an enzymatic mechanism, using the same catalytic groups which the enzyme uses and examining the question of whether a proposed mechanism for the enzymatic process is reasonable or ...

On the Chemical Control of Cellular Growth

New England Journal of Medicine, 1969
When the lobster loses a claw, it will grow a new one; when a peripheral nerve is cut, it can regenerate; and as discussed by Malt in the current issue, when one kidney is removed, the remaining me...
