Degree of substitution

In this study, cellulose nanocrystals (CNC) were chemically extracted from the waste newspapers and acetylated by reacting CNC with acetic anhydride, using sulfuric acid as a catalyst.

This paper estimated the degree of elasticity substitution of inputs, particularly young labor, older labor, and physical capital. The elasticity of input substitution was estimated using a nested constant elasticity of substitution (CES) production function and nonlinear regression analysis. Research data were obtained from the annual secondary data of government sources from 1990 to 2013. The findings indicated that the input substitutability of young and older labor was low. However, capital and labor could substitute for each other.

Two paralogous genes,maeEandcitM, that encode putative malic enzyme family members were identified in the Enterococcus faecalisgenome. MaeE (41 kDa) and CitM (42 kDa) share a high degree of homology between them (47% identities and 68% conservative substitutions). However, the genetic context of each gene suggested thatmaeEis associated with malate utilization whereascitM is linked to the citrate fermentation pathway.

Severity is highly variable. Known modulating factors are those that ameliorate the burden of unpaired α-globin inclusions. Alleles associated with milder synthetic defects and co-inheritance of α-thalassemia trait reduce clinical severity by reducing accumulation of excess α globin. HbF persists to various degrees in β-thalassemias. γ-Globin gene chains can substitute for βchains, generating more hemoglobin and reducing the burden of α-globin inclusions. The terms β-thalassemia major and β-thalassemia intermedia are used to reflect the clinical heterogeneity.
