Research on the Correlation Between Oil Menitoring and Vibration Monitoring in Information Collecting and Processing Monitoring

Oil monitoring and vibration monitoring are two principal techniques for mechanical fault diagnosis and condition monitoring at present. They monitor the mechanical condition by different approaches, nevertheless, oil and vibration monitoring are related in information collecting and processing. In the same mechanical system, the information obtained from the same information source can be described with the same expression form. The expressions are constituted of a structure matrix, a relative matrix and a system matrix. For oil and vibration monitoring, the information source is correlation and the collection is independent and complementary. And oil monitoring and vibration monitoring have the same process method when they yield their information. This research has provided a reasonable and useful approach to combine oil monitoring and vibration monitoring.

Informal Sector Solid Waste Collection and Recycling in Zaria, Nigeria

Management of solid wastes has become a critical issue for almost all the major cities in Nigeria. Although the responsibility for solid waste management remains primarily with the local government councils, several other stakeholders are playing significant roles in the system. In Zaria, the scavengers, waste pickers and collectors eke out a living by collecting waste and selling recyclable materials out of the urban solid wastes. The paper utilized data collected using questionnaire survey, in-depth discussion guides and open-ended interviews to examine the socio-economic characteristics, the functions, aspects of involvement of children, the working conditions and problems of waste collectors and pickers in Zaria. The paper found that the sector is the only means of solid waste collection in several sections of the town and is a source of livelihood for the poor. The activities help in realizing the aim of modern waste management, that is to move up the solid waste management hierarchy by reducing reliance on disposal and increasing recycling. In spite of these important functions, informal waste collection and recycling are associated with problems of unsanitary conditions and health risks to the communities and the waste collectors. Recommendations have been made to integrate the informal sector into the formal waste management by incorporating the employment needs of the urban poor and enhancing the efficiency of government in addressing the main problems.

Survey of the Creditor＇s Ability to Collect and Use the Enterprise Information

This paper is concerned with the analysis of the creditor＇s ability to collect, analyze and judge business information, which is a realistic problem for the bank to control the risk of loan effectively.

Disinfection byproducts in drinking water and regulatory compliance： A critical review

Disinfection by-products （DBPs） are regulated in drinking water in a number of countries. This critical review focuses on the issues associated with DBP regulatory compliance, including methods for DBP analysis, occurrence levels, the regulation comparison among various countries, DBP compliance strategies, and emerging DBPs. The regulation comparison between China and the United States （US） indicated that the DBP regulations in China are more stringent based on the number of regulated compounds and maximum levels. The comparison assessment using the Information Collection Rule （ICR） database indicated that the compliance rate of 500 large US water plants under the China regulations is much lower than that under the US regulations （e.g. 62.2% versus 89.6% for total trihalomethanes）. Precursor removal and alternative disinfectants are common practices for DBP regulatory compliance. DBP removal after formation, including air stripping for trihalomethane removal and biodegradation for haloacetic acid removal, have gained more acceptance in DBP control. Formation of emerging DBPs, including iodinated DBPs and nitrogenous DBPs, is one of unintended consequences of precursor removal and alternative disinfection. At much lower levels than carbonaceous DBPs, however, emerging DBPs have posed higher health risks.

Evaluate HAA removal in biologically active carbon filters using the ICR database

The effects of biologically active carbon(BAC)filtration on haloacetic acid(HAA)levels in plant effluents and distribution systems were investigated using the United States Environmental Protection Agency’s Information Collection Rule(ICR)database.The results showed that average HAA5 concentrations in all locations were 20.4μg·L^(-1)and 29.6μg·L^(-1)in ICR plants with granular activated carbon(GAC)and ICR plants without GAC process,respectively.For plants without GAC,the highest HAA levels were observed in the quarters of April to June and July to September.However,for plants with GAC,the highest HAA levels were observed in the quarters of April to June and January to March.This HAA level profile inversely correlated well with water temperature,or biologic activity.For GAC plants,simulated distribution samples matched well with distribution system equivalent samples for Cl3AA and THMs.For plants with and without GAC,simulated distribution samples overestimated readily biodegradable HAAs in distribution systems.The study indicated that through HAA biodegradation,GAC process plays an important role in lowering HAA levels in finished drinking water.
