Microbiological tests were carried out to evaluate a new chlorine dioxide sterilant: Tristel OneShot. Preliminary in vitro suspension tests showed that solutions containing around 140 ppm chlorine dioxide achieved a reduction factor exceeding 10(6) of Staphylococcus aureus in 1min and of Bacillus subtilis spores in 2.5 min in the presence of 3g/L bovine albumin. Subsequent tests evaluated the e...

long-term success of endodontic treatment is precisely and completely dependent on adequate and appropriate cleaning and shaping of the root canal along with proper and correct obturation of the entire prepared space. this paper aims to report an exceptionally and novel non-surgical and orthograde endodontic therapy on maxillary right central incisor with an extensive radiolucent lesion. a 17-y...

The association between moral purity and physical cleanliness has been widely discussed recently. Studies found that moral threat initiates the need of physical cleanliness, but actual physical cleaning and priming of cleaning have inconsistent effects on subsequent attitudes and behaviors. Here, we used resting-state functional magnetic resonance imaging to explore the underlying neural mechan...

UNLABELLED Vacuum cleaners with a central exhaust may lead to lower airborne dust and allergen concentrations compared with regular vacuum cleaners. In 12 houses, equipped with a central vacuum cleaning system, a standardized vacuum cleaning protocol was performed comparing airborne dust and allergen concentrations between the central system and a regular cleaner. Airborne dust concentrations d...

This paper discusses the current developments within a novel environment to perform related model-based activities. In particular, the paper focuses in the modules corresponding to data preprocessing and dynamic data reconciliation. In terms of the former module, this work discusses the implementation of three approaches based on the minimum median distance (MMD), the moving median (MM), and th...

The outlier detection is an important preprocessing routine that is required to ensure robustness of the sensory data analysis. Several factors make the wireless sensor networks (WSNs) especially prone to outliers. A sensor network is equipped with thousands of inexpensive, low fidelity nodes, which can easily generate sensing errors. Since these networks include a large number of sensors, the ...

In general, the aim of our research is to adapt computational intelligence methods for computer-aided decision support in diagnosis and therapy of persons with Autism Spectrum Disorders (ASDs). In the paper, we are focusing on the data preprocessing step for cleaning a training data set for classifiers. An approach based on consistency factors is proposed.

Web log data is usually diverse and voluminous. This data must be assembled into a consistent, integrated and comprehensive view, in order to be used for pattern discovery. Without properly cleaning, transforming and structuring the data prior to the analysis, one cannot expect to find meaningful patterns. As in most data mining applications, data preprocessing involves removing and filtering r...

It is challenging to conduct statistical analyses of complex scientific datasets. It is a timeconsuming process to find the relationships within data for whether a scientist or a statistician. The process involves preprocessing the raw data, the selection of appropriate statistics, performing analysis and providing correct interpretations, among which, the data pre-processing is tedious and a p...

OBJECTIVES The objective of this regional study across Wales was to perform a preliminary examination of Welsh emergency vehicles to determine levels of bacterial contamination. METHODS Specific sites within emergency vehicles were swabbed, before and after vehicle cleaning, over a 12 month period, on a monthly basis. All swabs were sent to pathology laboratories for culturing and analysis. ...
