In the cement industry, however, this link is weak. The industry's record of value creation is spotty, with ROIC levels roughly equal to the cost of capital, at around 9 percent. Behind the lackluster ROIC, two drivers stand out: high goodwill (seen in the low tangible capital ratio) and inadequate capital efficiency. Call it bad timing.

Introduction: Clinical decision-making is a daily practice conducted by medical practitioners, yet the processes surrounding it are poorly understood. The influence of 'shortcuts' in clinical decision-making, known as heuristics, remains unknown. This paper explores heuristics and the valuable role they play in medical practice, as well as offering …

These airslide fabrics are used for the pneumatic conveying of fine dry products like cement, also called "pulverulents". The airslide consists of a chamber separated by a permeable cloth. The chamber is inclined at a very slight angle (as low as 1.5°). Compressed air is injected into the lower chamber which then goes through the media …
