The first general metric for green chemistry remains one of the most flexible and popular ones. Roger A. Sheldon’s environmental factor (E-factor) can be made as complex and thorough or as simple as desired and useful. [10] The E-factor of a process is the ratio of the mass of waste per mass of product:
If the Benchmark score is determined by the transformation products, the Benchmark score will include a subscript of TP. CoHC - Chemicals of High Concern (polymer residuals & catalysts): Version 1.4 of the GreenScreen added special rules for benchmarking polymers which include analysis of residual monomers and/or catalysts present at or above ...
The following diagnostic systems and rating scales are used in psychiatry and clinical psychology. This list is by no means exhaustive or complete. This list is by no means exhaustive or complete. For instance, in the category of depression, there are over two dozen depression rating scales that have been developed in the past eighty years.
Green chemistry, similar to sustainable chemistry or circular chemistry, [1] is an area of chemistry and chemical engineering focused on the design of products and processes that minimize or eliminate the use and generation of hazardous substances. [2]
The simplest definition was introduced by Barry Trost in 1991 and is equal to the ratio between the mass of desired product to the total mass of reactants, expressed as a percentage. The concept of atom economy (AE) and the idea of making it a primary criterion for improvement in chemistry, is a part of the green chemistry movement that was ...
The goal in designing a reliable instrument is for scores on similar items to be related (internally consistent), but for each to contribute some unique information as well. Note further that Cronbach's alpha is necessarily higher for tests measuring more narrow constructs, and lower when more generic, broad constructs are measured.
When interpreting the clinical scales, the authors recommend that qualified professionals interpret the Severe Clinical Syndrome scales before the Clinical Syndrome scales as the pattern of responding indicated by the Severe Clinical Syndrome scale scores may also affect the scores on the Clinical Syndrome scales (e.g. if an individual scores ...
The ASEBA was created by Thomas Achenbach in 1966 as a response to the Diagnostic and Statistical Manual of Mental Disorders (DSM-I). [3] This first edition of the DSM contained information on only 60 disorders; the only two childhood disorders considered were Adjustment Reaction of Childhood and Schizophrenic Reaction, Childhood Type.
