Book Description
Legionella spp. are ubiquitous microorganisms that are widely distributed in aquatic environments. Water systems of large buildings, such as hospitals, hotels, and rental units are often contaminated by legionellae and various parameters such as physical, chemical, and microbial building water system characteristics can influence Legionella occurrence. A range of physical and chemical disinfection methods have been proposed to control Legionella contamination; however, to date, the most effective procedures have not been defined. There is a need to survey legionellae in water systems to prevent legionellosis. Although the assessment of L. pneumophila in water is typically performed by culture isolation on selective media, it has several limits. For this reason, alternative tools for rapid, sensitive, and specific detection of Legionella in water samples have been proposed. In order to increase knowledge on different aspects of Legionella contamination in the water environment, this book gathers research studies related to the occurrence of Legionella in water systems of different environments; the role of different factors that can influence the Legionella contamination, as well as the advantages and disadvantages of different methodological approaches.

Book Description
Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.

Book Description
The articles collated for this issue will largely be based on presentations at the 10th International Legionella' Conference in Yokohama (Chair: Professor Kazuhiro Tateda, September 20-24/2022), which, because of the impact of Legionella' disease with unknown pathogenicity and unexplained ecology, likewise, the need for new rapid test innovations will be held entirely as a hybrid on-site and online conference.

Book Description
This edited collection explores disease transmission and the ways that the designed environment has promoted or limited its spread. It discusses the many design factors that can be used for infection and disease control through lenses of history, public health, building technology, design, and education. This book calls on designers to consider the role of the built environment as the primary source of bacterial, viral, and fungal transfers through fomites, ventilation systems, and overcrowding and spatial organization. Through 19 original contributions, it provides an array of perspectives to understand how the designed environment may offer a reprieve from disease. The authors build a historical foundation of infection and disease, using examples ranging from lazarettos to leprosy centers to show how the ability to control infection and disease has long been a concern for humanity. The book goes on to discuss disease propagation, putting forth a variety of ideas to control the transmission of pathogens, including environmental design strategies, pedestrian dynamics, and open space. Its final chapters serve as a prospective way forward, focusing on COVID-19 and the built environment in a post-pandemic world. Written for students and academics of architecture, design, and urban planning, this book ignites creative action on the ways to design our built environment differently and more holistically. Please note that research on COVID-19 has exponentially grown since this volume was written in October 2020. References cited reflect the evolving nature of research studies at that time.

Book Description
The coronavirus disease (COVID-19) pandemic has had a wide-ranging and substantial impact on the water sector in Asia and the Pacific. This guidance note focuses on how service providers—particular those involved in supply, sanitation, and wastewater treatment—have been affected and the response measures they have undertaken. It also identifies potential pathways to shape a post-pandemic recovery for the sector and the role of the Asian Development Bank (ADB) in supporting this. The guidance note is one of a series produced by ADB for key sectors and thematic areas.

Book Description
'Building Control Systems' provides the building services engineer with a comprehensive understanding of modern control systems and relevant information technology. This will ensure that the best form of control systems for the building is specified and that proper provision is made for its installation, commissioning, operation and maintenance. Beginning with an overview of the benefits of the modern building control system, the authors describe the different controls and their applications, and include advice on their set-up and tuning for stable operation. There are chapters on the practical design of control systems, how to work from the hardware components and their inclusion in networks, through to control strategies in Heating, Ventilation and Air Conditioning (HVAC) systems and whole buildings. The relationship between Building, Management Systems (BMS) and information technology systems is discussed, and the building procurement process and the importance of considering control requirements at an early stage in the design process

Book Description
The COVID-19 pandemic has presented unprecedented challenges to the nation's K-12 education system. The rush to slow the spread of the virus led to closures of schools across the country, with little time to ensure continuity of instruction or to create a framework for deciding when and how to reopen schools. States, districts, and schools are now grappling with the complex and high-stakes questions of whether to reopen school buildings and how to operate them safely if they do reopen. These decisions need to be informed by the most up-to-date evidence about the SARS-CoV-2 virus that causes COVID-19; about the impacts of school closures on students and families; and about the complexities of operating school buildings as the pandemic persists. Reopening K-12 Schools During the COVID-19 Pandemic: Prioritizing Health, Equity, and Communities provides guidance on the reopening and operation of elementary and secondary schools for the 2020-2021 school year. The recommendations of this report are designed to help districts and schools successfully navigate the complex decisions around reopening school buildings, keeping them open, and operating them safely.
