Abstract: LDL (Learning Design Language) is an educational modelling language which was designed to model collaborative activities. This paper details the solution proposed to address, with LDL and the associated infrastructure LDI, the two steps presented in the workshop “Comparing Educational Modelling Languages on a case study”. The modelling of the case study is described in detail. Its “op...

Editor’s Note: A serious shortage of hospital nurses in the U.S., evident in the past decade, is expected to continue and worsen in the next 15 years. Increasingly, the public and the health professions are acknowledging that nurse understaffing represents a serious threat to patient safety in U.S. hospitals.

Land uses are pivotal in global carbon cycles. The native forest lands possess a greater potential to sequester higher carbon, which can directly address soil quality and climate change problems. Unfortunately, the rapid conversion of forests other land use over past few decades has significantly declined concentration soils. Therefore, order estimate impact land-use (LUC) on status, this prese...

Hot, massive (OB) stars experience strong line-driven stellar winds and mass loss. As the majority of efficient driving lines are metallic, amount wind loss is dependent on metallicity Z. In addition, intrinsically inhomogeneous clumpy. However, to date, neither theoretical nor empirical studies have investigated how such clumping may also depend We theoretically degree due line-deshadowing ins...
