Six-Letter Connoisseur\u27s Ladders

By the time we reach six-letter words, conditions for superior ladders are much improved: nearly one-half of six-letter words are heterograms (all letters are different), the fraction of isolanos (words which have no neighbours) decreases to less than one-tenth, there is a reasonable number of onalosis (words which have neighbours for each letter change), and each word has on average almost six neighbours (one for each letter). In this article, we therefore only consider ladders in which the terminal words are heterograms, with corresponding letters different, and with letters replaced in order. Even so, there are about fifty thousand of them

Closing the STEM Gap: A University, P-12 School District Partnership to Engage Sixth Grade Students in Integrated Computing Activities

This article describes how participating in a computing program positively impacted young adolescents from underrepresented populations in STEM attitude toward STEM and interest in STEM- related careers. Nineteen sixth-grade students attending a rural, Title I middle school participated in the study. Five computing lessons were taught by undergraduate interns majoring in computer science, middle-level mathematics and science teacher education, and secondary mathematics teacher education. Analysis of quantitative and qualitative data provide convincing evidence that students’attitudes toward STEM improved and interests in STEM-related careers increased because of participating in the computing program

E-Learning and Digital Education in the Twenty-First Century

E-learning and digital education approaches are evolving and changing the landscape of teaching and learning at all levels of education throughout the world. Innovation of emerging learning technologies is assisting e-learning and digital education to meet the needs of the 21st century. Due to the digital transformation of everyday practice, the process of learning and education has become more self-paced and accessible at any time from anywhere. The new generations of digital natives are growing up with a set of skills through their engagement with the digital world. In this context, this book includes a collection of chapters to facilitate continuous improvements including flexibility and accessibility in e-learning and digital education by exploring the challenges and opportunities of innovative approaches through the lenses of current theories, policies, and practices

Align PHA Scenarios with PSV Calculation Cases

PresentationIt is not uncommon to find that Process Hazard Analysis (PHA) scenarios and Process Safety Valve (PSV) calculation cases do not align. The intent of PHA studies, typically performed using the Hazard and Operability (HAZOP) method, is to identify all plausible hazard scenarios and the risk of those events occurring by assessing potential causes, consequences, safeguards, and independent protection layers. The intent of the PSV protection layer is to provide relief capacity for all plausible overpressure scenarios. Therefore, HAZOP scenarios related to overpressure and PSV calculation cases should align. Lack of alignment between the HAZOP and the PSV calculation file creates problems in completeness, quality, and clarity. Lack of alignment also creates engineering rework and “churn” as inconsistencies are discovered and resolution is needed. A simple solution is proposed. Each PSV calculation case that is considered plausible should contain a direct reference to the related HAZOP scenario, preferably in the summary matrix. Likewise, each HAZOP scenario should reference the related PSV case. New or modified PSV calculations and new or modified HAZOP summary sheets associated with plant modifications or engineering document corrections should include this cross- referencing. Where broader changes are introduced, such as changes to engineering assumptions for PSV calculations or changes to HAZOP scenario protocol, the Discipline Subject Matter Experts (SMEs) responsible for approving those changes must consider the impacts to the related documents and define the expectations for updating those documents in order to assure alignment

STEAME Model in Action: Challenges and Solutions in Mastering the Digital Culture

Due to the digital transformation of everyday practice the process of education has become more complicated than ever before. The role of teachers is more complex as they are not the only source of information and knowledge for their students anymore. Formally or informally, they need to help students develop new competencies and prepare them for the unknown future in the fast-growing and changing labor market. Essential part of these new competencies lies in the interconnected fields of Science, Technology, Engineering and Mathematics. In order for students to obtain them a variety of learning approaches have to be applied in an interdisciplinary educational environment and digital culture. The new generations of digital natives grow up with a set of skills about engaging in the digital world as a basic knowledge. Furthermore, to provide students with more holistic understanding the concepts of Arts are integrated with STEM to become STEAM education. This chapter presents extended education model taking STEM and STEAM to the next level and bringing the Entrepreneurship discipline to create an integrated STEAME curriculum. This chapter presents an integrated STEAME curriculum model, methodology for its implementation and STEAME classroom and environment design as a new education approach to tackle the challenges of the development of skills for the 21st century

Measuring the Water Retention of Coating Colors

The water holding properties of coating colors are important for both finished sheet properties and proper runnability on the coater. A test cell was constructed which is capable of measuring water retention of coating slips and predicting water hold out of base papers. The study showed that enzyme conversion time of starch was inversely related to viscosity and water retention. Also the level of sizing was determined to have the greatest influence on water hold out of base stocks
