Anion chromatography with conductivity detection was chosen as the analytical technique for the development of a cleaning validation method for clean-in-place (CIP) detergents. The method was developed and validated for the determination of traces of the detergent CIP-200. It was shown to be linear with a squared correlation coefficient (r(2)) of 0.9999 and the accuracy experiments presented av...

BACKGROUND AND OBJECTIVES The Behavioral Pain Scale is a pain assessment tool for uncommunicative and sedated Intensive Care Unit patients. The lack of a Brazilian scale for pain assessment in adults mechanically ventilated justifies the relevance of this study that aimed to validate the Brazilian version of Behavioral Pain Scale as well as to correlate its scores with the records of physiologi...

OBJECTIVE In high-burden Australian states and territories, registers of patients with acute rheumatic fever and rheumatic heart disease are maintained for patient management, monitoring of system performance and research. Data validation was undertaken for the Australian Northern Territory Rheumatic Heart Disease Register to determine quality and impact of data cleaning on reporting against ke...

LEVEL: INTERMEDIATE C hromatography columns can become contaminated by a variety of protein and nonprotein species during a purification campaign. Consequences of column contamination include an increase in backpressure, loss of signal resolution, altered product yield, and medium discoloration. Common chromatographic contaminants include • residual proteins • nucleic acids • lipids • endotoxin...

The paper presents the study of design and synthesis of the system dedicated for sweeping large and complex spaces using a team of cleaning robots. The problems of coordination of activities of individual robotic-unit is discussed. Application of the Game Theory for creation of coordination algorithms is proposed. The paper deals also with design and implementation of algorithms of movement of ...

ETL (Extract-Transform-Load) systems are formed by processes responsible for the extraction of data from several sources, cleaning and transforming it in accordance with some prerequisites of a data warehouse, and finally loading it in its multidimensional structures. ETL processes are the most complex tasks involved within the development of a Data Warehousing System, being crucial to model th...

In this article we present a novel algorithm for uniform coverage of a region. Surveillance, cleaning, and mine detection are some applications that would benefit from this type of algorithm. Prior work has claimed that this task is impossible to solve for non–convex regions [7]. Our algorithm enables robots to uniformly cover arbitrary path–connected regions, such that the robot movements are ...

Hand hygiene, cleaning and disinfection are pre-requirements for hygiene management in hospital settings and the food industry. In order to facilitate risk management, different contamination scenarios and interventions need to be evaluated. In the present study data on transfer rates and reductions of Staphylococcus aureus were provided in an experimental set-up using artificial skin. Using th...
