The chemical control of respiration
Annals of Biomedical Engineering, 1981Arterial blood gas tensions are maintained at appropriate levels through a feedback system which adjusts ventilation and has multiple inputs and outputs. Inputs to the system arise mainly from peripheral and central chemoreceptors, but there are other inputs from mechanoreceptors and higher brain centers.

Control of Chemical Pollutants
Nature, 1970Concern for environmental quality and consumer safety is burgeoning, and some classic assumptions of industrial society are being challenged. Now that apparent conflicts have developed between the needs for continued economic growth and environmental management it is timely to review some of the basic problems of chemical pollution, to develop methods ...

Integration of Biological and Chemical Control: Specifications for Chemical Control
Bulletin of the Entomological Society of America, 1962About 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 ...

Controlling Chemical Reactivity with Antibodies
Science, 1993The 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 ...

CONTROL IN A CHEMICAL ENGINEERING COURSE
IFAC Proceedings Volumes, 1988Abstract The requirements of a course in control for Chemical Engineers are discussed and the place of traditional control theory in such a course questioned. A syllabus for a short course is presented which should provide a basic level of understanding for the non specialist. The lecture, tutorial and practical content is chosen to maintain interest

Chemical Control System of Epigenetics
The Chemical Record, 2018Abstract 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 ...
