Polyurethane Foam Molding Technologies for Improving Total Passenger Compartment Comfort
Improvements in passenger compartment comfort continue to be one of the key needs of the global transportation industry. Since their introduction more than 40 years ago, flexible molded polyurethane foams have successfully contributed to the comfort provided by all forms of transportation seating. Initially required to provide just a wide range of load bearing, seating foams are now being desig...
متن کاملStudy Progress of Biodegradability
Biodegradability , are known as biological degradation degree of biodegradable organic pollutants by microorganisms. Organic biodegradability can be divided into aerobic biodegradability and anaerobic biodegradability. At present, evaluation methods for biological degradation degree include aerobic biodegradability method of relative oxygen consumption or rate method, integrated test evaluation...
متن کاملBiodegradability of Plastics
Plastic is a broad name given to different polymers with high molecular weight, which can be degraded by various processes. However, considering their abundance in the environment and their specificity in attacking plastics, biodegradation of plastics by microorganisms and enzymes seems to be the most effective process. When plastics are used as substrates for microorganisms, evaluation of thei...
متن کاملExperiments in Predicting Biodegradability
We present a novel application of inductive logic programming (ILP) in the area of quantitative structure-activity relationships (QSARs). The activity we want to predict is the biodegradability of chemical compounds in water. In particular, the target variable is the half-life in water for aerobic aqueous biodegradation. Structural descriptions of chemicals in terms of atoms and bonds are deriv...
متن کاملPredicting Biodegradability using Thermodynamic Descriptors
The ability to predict the biodegradability of a given compound is crucial in understanding the fate of this compound in the environment, which can have tremendous public health implications. Traditionally, the biodegradability prediction relies on the regression analysis utilizing quantitative structural relationships. This paper presents a novel prediction method utilizing neural networks and...
