here, in situ synthesis of nano zinc oxide, along with aminolysis of polyester fabric, has simultaneously been carried out by using triethanol amine (tea) and zinc acetate. the zno nano particles (nps) were formed and stabilized on the fabric surface by amine compound at 130 °c for 1 h. the synthesis of nano zno particles on the polyester fabric were confirmed by x-ray diffraction (xrd) pattern...

Stethoscope diaphragms are frequently colonized by bacteria. This cross-sectional study described the frequency and factors associated with reporting ever cleaning stethoscopes among 408 medical students and doctors at a medical college and 2 teaching hospitals in Rawalpindi, Pakistan. A minority of the respondents (37.7%) reported having ever cleaned their stethoscope. Following normal clinica...

This paper proposes the idea of establishing an extensible data cleaning framework which is based on the key technology of data cleaning, and the framework includes open rules library and algorithms library. This paper gives the descriptions of model principle and working process of the extensible data cleaning framework, and the validity of the framework is verified by experiment. When the dat...

BACKGROUND We investigated the associations between traditional and environmentally preferable cleaning product exposure and dermal, respiratory, and musculoskeletal symptoms in a population of custodians. METHODS We analyzed associations between symptoms and exposure to traditional and environmentally preferable cleaning product exposure among 329 custodians. RESULTS We observed increased ...

We demonstrate XClean, a data cleaning system specifically geared towards cleaning XML data. XClean’s approach is based on a set of cleaning operators. Users may specify cleaning programs by combining operators using the declarative XClean/PL language, which is then compiled into XQuery. We plan to show XClean in action on several scenarios based on real-world data. A graphical user interface s...

The past efforts made on the corn cleaning dynamics were reviewed. Based on Discrete Element Method model, a simulation method for corn cleaning dynamics was then proposed, composing the following design factors: 1. 2-D discrete model and its related factors; 2. parities and magnitude of computation, consideration of the two factors upon application; 3. test platform design. The implementation ...
