Can we prevent future building damage from sulfides in aggregates?

In recent years, tens of thousands of homes, commercial and institutional buildings have sustained severe structural damage due to the aggregates used in construction not being inert. An excess of naturally occurring reactive iron sulfides in the rock, is all that it takes to cause devastation within a few years of construction. These largescale problems have occurred in the United States, Canada and Ireland, despite these countries having well established building codes and standards. A new book explores how excess sulfides, mainly pyrite and pyrrhotite, in aggregates can be defined and identified in advance and it describes how the risk of future damage can be quantified. In keeping with the theme of Pyrite & Pyrrhotite, the book will also feature some innovative research into sustainable uses of pyrite.

BOOK TITLE: Sustainable and Healthy Building Environments

This book addresses a topic of great relevance today, considering that in developed countries, most of the time is spent indoors; therefore, indoor residential environments have a direct influence on human health. Furthermore, in developing countries, significant levels of indoor pollution make housing unsafe, which has an impact on the health of its inhabitants; thus, housing is a key factor in the health of people around the world. In this book we look at a range of innovative research and evidence-based policy ideas that demonstrate the importance of housing research and policy for health and well-being.

Do we need Metal Matrix Composites in the future?

Developing production technology tries to respond to unlimited human needs. Meeting these needs requires the development of new products or an increase in the supply of raw materials  Although polymer-based, recycled and natural resources are used as raw materials, it does not reduce the importance of metal-based structures. However, there is a need to use […]

Green Energy Harvesting Techniques for Sustainable Internet of Things

IoT ecosystems consists of diverse heterogeneous IoT devices. These devices consumes power. Different Green energy harvesting mechanisms may be employed . This leads to power saving, imporved performance, increased life-time, envrionment saving. Still a long way to go for producing sustainable ways to gear up these IoT devices with power using green energy harvesting mechanisms.

ABCs of COVID-19: Airway control, CPR, Basic/Advanced Cardiac Life Support with special regard to COVID-19 spread

It is well established that a substantial portion of patients with COVID-19 deteriorate, become critically ill and die eventually. Airway interventions are the ‘A’ of the alphabet of all resuscitative procedures, which can save the lives of the victims of COVID-19 and many other life-threatening emergencies. On the other hand, resuscitative procedures pose the greatest risk for disease transmission. Unlike many other personnel, one of the most important problems healthcare worker (HCW) face in CPR / ACLS is being unaware of the given patient’s infection status or contagiousness related to COVID-19. Aerosolization is triggered primarily by procedures including CPR, laryngoscopy, endotracheal intubation (ETI), ventilation management, and other advanced interventions. The use of personal protective equipment (PPE) is vital in all procedures and interactions with patients in pandemic period. For example, If ETI and ventilation is performed with a closed circuit, the risk of transmission is very low if a ventilator with high-efficiency particulate air (HEPA) filter is used. Mouth-to-mouth breathing is being abandoned in this pandemic era. The aim of this chapter is to highlight the indications and drawbacks of these maneuvers in the pandemic era, together with necessary protective measures for HCW.

How is quantum ground state brought to its excited state?

Following the idea is my theory called Periodic Quantum Gravity and Cosmology, which is Chapter 1 in the book “The Wave Equation: An Overview” In this theory, the universe arise from the fundamental substance of the universe which is infinite indivisible and perfectly motionless like ocean without waves. All fundamental particles are created in […]

The modified fishbowl for online active learning classrooms

Introduction Active learning means engagement with the course elements and is best manifested when students are busy doing classroom activities and complete outside class work and assignments (Shawer, 2022a; Shawer, 2017). Since positive relationships between academic success and active learning have been established across many disciplines, a professional responsibility is placed on every teacher to […]

The modified fishbowl for active learning classrooms

Introduction Active learning takes place when students get engaged with the course elements, take responsibility over learning, are motivated to pursue inside and outside classroom learning, and when they are active participants in classroom activities. Since a large volume of research confirms that active learning improves both the process and outcome of learning, instructors should […]
