We assessed the adenosine triphosphate luminometer as a tool for point-of-cleaning education. Following a terminal cleaning, infection preventionists met with cleaning staff and used the luminometer to evaluate multiple surfaces; 820 surfaces in 210 rooms were sampled. The mean proportion of clean surfaces improved significantly over the study period, P = .012. These findings suggest that direc...
In many industrial processes, particle contamination is becoming a major issue. Particle detachment from surfaces can be detrimental, e.g. during lithographic processing. During cleaning however, detachment is aimed for. However, until recently, only little is known on the mechanism of particle detachment due to flowing gasses. In high throughput applications, large gas velocities are likely to...
The contribution refers a tworobots system purposely designed to clean internal environments subjected to hygiene regulations. The mechanical design oriented to the life cycle has been developed. The tests and validation of the various solutions considered has been carried out using different simulation and virtual reality tools. Virtual mock-up is efficient design help when, as the present pro...

OBJECTIVE To evaluate the use of ear endoscopy in the postoperative management of open mastoidectomy cavities, and to test whether ear endoscopy improves inspection and cleaning compared with ear microscopy. METHODS Prospective study. Thirty-two ears were divided into two groups: group 1, examination and cleaning of mastoid cavities under endoscopic visualization after microscopic standard ea...
Ultrafiltration (UF) of whey is a major membrane based process in the dairy industry. However, commercialization of this application has been limited by membrane fouling, which has a detrimental influence on the permeation rate. There are a number of different chemical and physical cleaning methods currently used for cleaning a fouled membrane. It has been suggested that the cleaning frequency ...
The purpose of this study is to test the prediction of the evolutionary theory of aging that human longevity comes with the cost of impaired reproductive success (higher infertility rates). Our validation study is based on the analysis of particularly reliable genealogical records for European aristocratic families using a logistic regression model with childlessness as a dependent (outcome) va...
BACKGROUND The objective of this study was to perform simulated-use testing as well as a clinical study to assess the efficacy of the EVOTECH Endoscope Cleaner and Reprocessor (ECR) cleaning for flexible colonoscopes, duodenoscopes, gastroscopes and bronchoscopes. The main aim was to determine if the cleaning achieved using the ECR was at least equivalent to that achieved using optimal manual c...
The problem of data cleaning, which consists of removing inconsistencies and errors from original data sets, is well known in the area of decision support systems and data warehouses. However, for some applications, existing ETL (Extraction Transformation Loading) and data cleaning tools for writing data cleaning programs are insufficient. One important challenge with them is the design of a da...
RATIONALE Cleaning tasks may imply exposure to chemical agents with potential harmful effects to the respiratory system, and increased risk of asthma and respiratory symptoms among professional cleaners and in persons cleaning at home has been reported. The long-term consequences of cleaning agents on respiratory health are, however, not well described. OBJECTIVES This paper aims to investiga...
