LEVEL: INTERMEDIATE L ast month, Part 1 of this article discussed some proven applications of chlorine dioxide (CD) gas and solutions as cleaning/sterilizing agents for isolators, process vessels, filter membranes, water systems, hard surfaces, and cleanrooms. Potential applications were also described, including the production of sterilized water from USP-grade water; sanitization of chromatog...

objective: the aim of this study was to evaluate and compare the cleaning ability and instrumentation time of manual and rotary methods used for preparation of primary anterior teeth. materials and methods: forty-four primary anterior teeth were used in this experimental study. access cavities were prepared and india ink was injected into the canals. the samples were divided into three groups a...

An increasing number of technology-dependent patients are sent home for long-term home-management of stable chronic illness. With a patient who is going to undergo tracheotomy, patient-education (for the patient and his/her caregivers) should begin early (before the tracheostomy, if possible), should be individualized to the patient, and should include basic airway anatomy, medical justificatio...

Ensuring high quality data when collecting and integrating information from heterogeneous sources into a data warehouse is a challenging problem. In this paper, we propose a model for XML data fusion, which allows the integrator to define data cleaning rules for solving value conflicts that may have been detected during the integration process. These rules resemble decisions that are made by us...

For cleaning silicon wafers via the RCA clean, temperature control is important for stable cleaning performance, but difficult owing that the RCA solutions expose nonlinear and time-varying exothermic chemical reactions. So far, the MSPC (model switching predictive controller) using the CAN2 has been developed and the effectiveness has been validated, where however we have observed that the con...

This paper discuss a dependency analyzer employing Support Vector Machines (SVMs) for Japanese spoken language. Most conventional dependency analyzers target written texts. Thus, we use a currently available spoken language corpus and make the SVMs learn the corpus to build a dependency analyzer that targets spoken language. We used two types of corpora: one contains written language, and the o...

Good data preparation is a key prerequisite to successful data mining [P99]. Conventional wisdom suggests that data preparation takes about 60 to 80% of the time involved in a data mining exercise [R97]. There have been good reviews of the problems associated with data preparation [F97, HS98 and MS97]. However the data cleaning aspect of data preparation is regarded as involving major human inp...

In the present study the structure of obsessive±compulsive phenomena in non-clinical adolescents was investigated by `The Padua Inventory' (PI). The PI is a self-report measure of obsessive and compulsive symptoms which is used in clinical and research settings. The use of PI in adolescents has been limited by the lack of normative data. Consequently, adolescent validation has both theoretical ...
