The Two Components of the RL ratio system: the RL Controlling-ratio system and RL balance sheet-ratio system

1997
The Controlling concept which bases on the RL ratio system (the name derives from the German“Rtentabilitat”, which is “profitability” in English and liquidity), presents a combination including descriptive, explanatory, and normative elements. Its enlarged version consists of the RL balance sheet-ratio system (RL-B) and the RL Controlling-ratio system (

Fundamentals of the RL ratio system

1997
The RL ratio system25, established by Reichmann/Lachnit26 (1976), represents a further development in the understanding of ratio systems. The RL system was designed for analysis purposes and, moreover, as an aid to management, in order to provide decision-making information within the framework of the planning and control process. As regards managerial

Generation of Reactive Oxygen Species and Degradation of Pollutants in the Fe2+/O2/Tripolyphosphate System: Regulated by the Concentration Ratio of Fe2+ and Tripolyphosphate.

Environmental Science and Technology, 2022
Tripolyphosphate (TPP) has many advantages as a ligand for the optimization of the Fe2+/O2 system in environmental remediation applications. However, the relationship between remediation performance and the Fe2+/TPP ratio in the system has not been ...

RV6RV5 voltage ratio in systemic hypertension

The American Journal of Cardiology, 1990
Abstract A ratio between the R-wave voltage of leads V 6 and V 5 >1.0 has been reported to be useful in the diagnosis of left ventricular (LV) hypertrophy in different clinical situations. 1 Recently, Spodick and Koito 2 studied the sensitivity and specificity of additional cutpoints 3 will be worthwhile.
