Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Despite the growing emphasis on corporate sustainability, it remains unclear whether firms will align with common ESG standards. The Phillips–Sul convergence methodology, in combination with dynamic time‐warping clustering, was utilized to analyze the ESG trajectories of 430 S&P 500 firms from 2019 to 2024.

Statistical Analysis of Compressive Strength of Concrete
Concrete is used in the construction practice as it is easily available, cheap, has flexibility of handling and can be shaped in any form desired. The use of concrete in the construction industry is now being done for a very long time. It is the most used material in the parts of structure where compressive strength is required.

Kinetic Contribution to the Arbitrary Order Odd Frequency Moments of the Dynamic Structure Factor
Contributions to Plasma Physics, EarlyView.ABSTRACT An exact expression is derived for the kinetic contribution to the odd (arbitrary order) frequency moments of the dynamic structure factor via a finite summation that features averages of even (all lower orders) powers of the momentum over the exact momentum distribution.

Experimental Study for Shear Behavior of Hybrid Self-Compacting Concrete Beams
Journal of Engineering and Sustainable Development, 2013 This paper discusses shear behavior of hybrid reinforced concrete beams that consist of two different concrete layers: the tension layer is made of normal strength concrete with compressive strength of 25 MPa and the compression layer is made of self ...

The uniaxial compressive strength of concrete: revisited
Materials and StructuresAbstractThis paper re-examines common notions and conventions regarding the compressive strength of concrete in general and of the uniaxial compressive strength of concrete in particular. A distinction is introduced between the strength of the specimen and the strength of the concrete as a material, and the commonly measured and adopted strength is ...
