BACKGROUND An urgent UK investigation was launched to assess risk of invasive Mycobacterium chimaera infection in cardiothoracic surgery and a possible association with cardiopulmonary bypass heater-cooler units following alerts in Switzerland and The Netherlands. METHODS Parallel investigations were pursued: (1) identification of cardiopulmonary(More)
Computational thinking has been identified as a necessary fundamental skill for all students. University curricula, however, are currently not designed to provide such knowledge to a broad student population. In this paper, we report on our experiences in the development of a model for incorporating computational thinking into the undergraduate, general(More)
Legionella pneumophila is the leading cause of Legionnaires' disease, a severe pneumonia that can occur as sporadic cases or point-source outbreaks affecting multiple patients. The infection is acquired by inhalation of aerosols from contaminated water systems. In order to identify the probable source and prevent further cases, clinical and environmental(More)
Household water systems have been proposed as a source of sporadic, community acquired Legionnaires' disease. Showers represent a frequently used aerosol generating device in the domestic setting yet little is known about the occurrence of Legionella spp. in these systems. This study has investigated the prevalence of Legionella spp. by culture and qPCR in(More)
In their recent article, Whiley makes an interesting case for the abolishment of routine testing in Legionella risk management and control plans. Here, we present our views regarding this suggestion, drawing upon our own experiences in the UK. We urge caution against the removal of routine monitoring from guidelines due to the impending public health risks(More)
First, a couple of anecdotes: While I was working on a class lecture a few days ago in my office, a " flash mob " showed up on the quadrangle in front of my window and danced to their iPods for a while before dispersing. Flash mobs were (briefly) a concern for police and other authorities in places like Minsk (Shirky, 2008, p. 165), Philadelphia (Urbina,(More)
In their recent article, Montagna et al. describe a multicenter study investigating the presence of Legionella in water and air samples of Italian healthcare facilities [1]. This is an interesting study that highlights some important gaps in our basic understanding of Legionella. One of the limitations of the study regarded the lack of information on the(More)
In a memorandum dated November 25, 1997, NRR requested RES to perform appropriate research and provide independent confirmation of the applicability of Arrhenius methodology to meet the environmental qualification (EQ) requirements for LOCA and post-LOCA environments. RES was requested to support the NRR reviews of licensees' requests for (1) power uprate(More)
