Beyond Conventional Cost–Benefit Analysis to Integrated Sustainability Assessment in Additive Manufacturing

Business Strategy and the Environment, EarlyView.
ABSTRACT Additive manufacturing (AM) adoption provides numerous benefits, including decentralised production, design flexibility, mass customisation, reduced material waste and lightweight designs. However, AM investment decisions are complex and challenging for manufacturers, and limited knowledge exists about the holistic assessment of relevant costs

Characterizing Low Falling Number in the Absence of Elevated Alpha‐Amylase Activity in Soft White Wheat and the Impact on Japanese Sponge Cakes

Cereal Chemistry, EarlyView.
ABSTRACT Background and Objectives Non‐alpha‐amylase induced low falling number was identified in 2024 soft white wheat. The objectives of this work were to characterize these low falling number samples and determine the impact on end‐product quality. The results were analyzed to determine differences in flour characteristics that might result in a low

COMPARATIVE ANALYSIS AND EVALUATION OF THE CONVERSION FORMULA FOR REBOUND NUMBER OF SCHMIDT HAMMER TEST AND UNCONFINED COMPRESSIVE STRENGTH TEST – CASE STUDY: ANDESITE ROCK SLOPE IN GRAHA PUSPA, LEMBANG FAULT

Rudarsko-geološko-naftni Zbornik
The Unconfined Compressive Strength (UCS) test is one of the most common methods for determining the rock material strength value. However, the size and complexity of the instrument do not allow UCS testing to be carried out in the field.

Age Factor on Estimating of Strength of Concrete in Structures by Rebound Hammer

Concrete Research and Technology, 2012
The relationship between the rebound number and strength of concrete varies as a function of the age of concrete, but the effect of age can generally be ignored for concrete between 3 days and 3 months old. However, for older concrete, it may be possible to develop the age factor of the rebound number of concrete taking into account the concrete's ...

Breadth at the Helm: Generalist CEOs and Corporate ESG Performance‐Evidence From China

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Drawing on the Upper Echelons Theory and the Imprinting Theory, this study conjectures that generalist CEOs may have a stronger tendency to pursue environmental, social and governance (ESG) goals. We perform multiple regression analyses with observations of Shanghai and Shenzhen A‐share listed companies from 2010 to 2023 in order to explore ...
