Relationship between environmental accounting information disclosure and enterprise value based on stakeholder theory

Published on 2025-07-10 by @OXFORD

Abstract: AbstractThe purpose of this study is to deeply analyze the impact of environmental accounting information disclosure (EAID) on corporate performance in order to fill the gaps in the current study. This study adopts stakeholder theory as guidance, constructs an evaluation index system for EAID, and combines multiple regression analysis to explore the impact of EAID on corporate performance. The results showed the environmental information disclosure index (EIDI) mean is 2.360, and the standard de[...]

A Compact Self-Decoupled In-Band Full-Duplex Monopole Antenna Based on Common- and Differential-Mode Theory

Published on 2025-07-10 by Yuejian Li, Yao Hu, Yu Luo @MDPI

Abstract: In-band full-duplex (IBFD) technology has attracted significant attention for its potential to double the spectral efficiency by enabling a simultaneous transmission and reception over the same frequency channel. However, achieving high isolation between closely spaced transmit and receive paths remains a critical challenge. In this paper, a novel compact co-polarized monopole antenna with self-decoupling capability is proposed based on common-mode/differential-mode (CM/DM) theory. By innovative[...]


Our summary: A novel compact monopole antenna design based on common-mode/differential-mode theory enables high isolation for in-band full-duplex technology, achieving over 20 dB isolation within the operating band.

An Evaluation of the Rheological and Filtration Properties of Cow Bone Powder and Calcium Carbonate as Fluid-Loss Additives in Drilling Operations

Published on 2025-07-10 by Humphrey Nwenenda Dike, Light Nneoma Chibueze, Sunday Ipinsokan, Chizoma Nwakego Adewumi, Oluwasanmi Olabode, Damilola Deborah Olaniyan, Idorenyen Edet Pius, Michael Abidemi Oke @MDPI

Abstract: Some additives currently used to enhance drilling mud’s rheological qualities have a substantial economic impact on society. Carboxymethyl cellulose (CMC) and calcium carbonate (CaCO3) are currently imported. Food crops have influences on food security; hence, this research explored the potential of utilizing cow bone powder (CBP), a bio-waste product and a renewable resource, as an environmentally friendly fluid-loss additive for drilling applications, in comparison with CaCO3. Bo[...]


Our summary: Evaluation of CBP and CaCO3 as fluid-loss additives in drilling operations, CBP shows superior rheological and fluid-loss control abilities compared to CaCO3, Fine-particle CBP with a 15g concentration produces the best mud characteristics
