Process computer applications in resin plants
IFAC Proceedings Volumes, 1977In the chemical industry many resin-type products are manufactured discontinuously in batch reactors. Besides closed loop control of such process variables as temperature and pressure a main control reauirement is time- and event-dependent on-off control through the the sequential processing stapes, fuch processes were formerly controlled using ...

Electron microscopy of resin-free sections of plant cells
Protoplasma, 1983A technique for producing resin-free sections of plant roots for observation with the high voltage electron microscope is described. The resulting images have high contrast and reveal a three-dimensional filamentous network in the cytoplasm and nucleoplasm. This network is briefly compared with the microtrabecular lattice found in animal cells.

Production scheduling of a multi-grade PET resin plant
Computers & Chemical Engineering, 2010We present a discrete-time, Mixed Integer Linear Programming (MILP) model for the production scheduling of a continuous-process multi-grade PET resin plant. The objective is to minimize the cost associated with grade changeovers in order to avoid undesirable variations in base resin properties and process conditions that occur during such changes.

Natural fiber composites with plant oil-based resin
Composites Science and Technology, 2004Abstract Vacuum-assisted resin transfer molding or resin vacuum infusion process was used to make composite panels out of plant oil-based resin [acrylated epoxidized soybean oil (AESO)] and natural fiber mats made of flax, cellulose, pulp and hemp.

Synthetic Ion-exchange Resins as a Medium for Plant Growth
Nature, 1963SEVERAL authors have examined the utilization of exchange resins as sources of plant nutrients1–5. The method generally used was to provide the required quantity of each nutrient in the exchanger phase without considering the resulting concentrations or ratios of these nutrients in the bulk solution.

A Follow-up Study of Workers at a Dye and Resin Manufacturing Plant
Journal of Occupational and Environmental Medicine, 1989A total of 2642 men employed at a dye and resin manufacturing plant in New Jersey were observed from the opening of the plant in 1952 through 1985, and their mortality rates were compared with the rates of United States white men. The workers' mortality experience was related to former employment at the Cincinnati Chemical Works, which had produced or ...

DNA Changes in Tissues Entrapped in Plant Resins (the Precursors of Amber)
Naturwissenschaften, 2000There have been many reports characterizing DNA from amber, which is a fossil version of plant resin. Here we report an investigation of the effects of plant resin (from Pseudotsuga menziesii) and drying conditions on the preservation of DNA in biological tissues.

Carbon isotope biogeochemistry of plant resins and derived hydrocarbons
Organic Geochemistry, 1998Abstract Hydrocarbons derived from plant resins are major components of some terrigenous oils and bitumens. These compounds are structurally distinct and this makes them useful biomarkers applicable in petroleum exploration as well as sources of biogeochemical information about palaeoenvironment and palaeobotany.
