Impact of ladder-related falls on the emergency department and recommendations for ladder safety

Knowledge management: the ladder of research utilization

Introduction: Knowledge management helps us to share, learn and regenerate the new knowledge. Knowledge is the most important asset and greatest competitive advantage of many organizations today. Simultaneously, it can be observed that many organizations realize it is highly problematic and complicated to collect, store, retrieve, find, disseminate and reuse knowledge in modern fast changing or...

the impact of attending efl classes on the level of depression of iranian female learners and their attributional complexity

می توان گفت واقعیت چند لایه ا ی کلاس های زبان انگلیسی بسیار حائز اهمیت است، زیرا عواطف و بینش های زبان آموزان تحت تاثیر قرار می گیرد. در پژوهش پیش رو، گفته می شود که دبیران با در پیش گرفتن رویکرد فرا-انسانگرایی ، قادرند در زندگی دانش آموزانشان نقش مهمی را ایفا سازند. بر اساس گفته ی ویلیامز و بردن (2000)، برای کرل راجرز، یکی از بنیان گذاران رویکرد انسانگرایی ، یادگیری بر مبنای تجربه، نوعی از یاد...

Safety properties verification of ladder diagram programs

Programmable Logic Controllers ensure the control of many reactive systems. These controllers are most of the time programmed with the languages defined in the IEC 61131– 3 standard. Our goal is the verification of safety properties of programs written in one of these languages: the Ladder Diagram. The main approaches in this field are based on ModelChecking. We propose in this article a Theore...

The birank number of ladder, prism and Mobius ladder graphs

Given a graph G, a function f : V (G)→ {1, 2, ..., k} is a k-biranking of G if f(u) = f(v) implies every u-v path contains vertices x and y such that f(x) > f(u) and f(y) < f(u). The birank number of a graph, denoted bi(G), is the minimum k such that G has a k-biranking. In this paper we determine the birank numbers for ladder, prism, and Möbius ladder graphs.
