Exploring Low‐Global Warming Potential Refrigerants for Medium‐Charge Systems

Energy Technology, EarlyView.
This study evaluates 15 low‐global warming potential (GWP) refrigerants as alternatives for medium‐charge systems, focusing on environmental impacts, operational performance, and system design integration. Key findings reveal R‐447A's suitability for standard climates and R‐454B's advantages in high ambient conditions, providing actionable guidance for

Arithmetic in Peano Arithmetic

2020
In this chapter, we take a closer look at Peano Arithmetic (PA) which we have defined in Chapter 1. In particular, we prove within PA some basic arithmetical results, starting with the commutativity and associativity of addition and multiplication, culminating in some results about coprimality.

Arithmetic is not arithmetic: Paradigm matters for arithmetic effects

Cognition
Research on arithmetic uses different experimental paradigms. So far, it is unclear whether these different paradigms lead to the same effects or comparable effect sizes. Therefore, this study explores how different experimental paradigms influence mental arithmetic performance, focusing on understanding the potential differences and similarities in ...

Children and Arithmetic

Journal of Child Psychology and Psychiatry, 1995
Abstract The development of children's understanding of mathematical relations and of their grasp of the number system is described. It is discussed that children easily recognise one‐way pan‐pan relations but that the number system at first causes them difficulty.
