Are Operating Margin, Markup and Unit Margin Good for Profit? An Approach Based on Microeconomic Theory

Managerial and Decision Economics, EarlyView.
ABSTRACT Managers often say that they want to make their company more profitable by increasing the unit margin, operating margin, or margin rate, making these strategic objectives. There is some confusion in their language, as these three metrics seem to be equivalent to maximum profit.

An Improved Mesh Stiffness Model for a Gear Tooth With Double Cracks on Both Sides Considering Opened and Closed States

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Research on the failure mechanisms of gears with multiple cracks has gained widespread attention. Among these, the study of the mesh stiffness characteristics of gears with multiple cracks is crucial for optimizing gear design and improving transmission reliability.

Sustainable two‐step functionalization of carbon fibers (CFs) with polyethyleneimine and investigation of curing kinetics in composite materials

Polymer Composites, EarlyView.
We followed the functionalization steps outlined in the figure to obtain carbon fibers (CFs) functionalized with branched polyethyleneimine (b‐PEI). The entire process was carried out under mild conditions, including plasma activation and low‐temperature heating, using an eco‐friendly solvent (water).

Effects of oxidation and silanization on the durability and tensile properties of carbon nanotube‐reinforced vinyl‐ester nanocomposites

Polymer Composites, EarlyView.
Schematic representation of the functionalization, processing steps, and tensile properties of carbon nanotube‐reinforced vinyl ester nanocomposites. Abstract Carbon nanotubes (CNTs) have received significant attention due to their exceptional physical and mechanical properties. Advancements in surface modification techniques have facilitated their use
