By using the samples of fine sand in Shanghai’s seventh layer, creep tests were performed to investigate deformation characteristics under different groundwater table change. It was revealed that is closely related change: when effective force caused by change smaller than pre-consolidation force, mainly elastic. When bigger compression large and rebound small; viscoelastic plastic equal stress...

Table 1. Standard air density as a function of elevation above sea level (at 70F and 50% relative humidity). M echanical ventilation can be divided into three types: negative-, positive-, and neutral-pressure ventilation. Negativepressure systems use fans to exhaust air, thereby creating a slight partial vacuum that draws fresh air in from outdoors. Negative-pressure ventilation systems are use...

Recently many applications and much software has been provided to support distributed authoring of file systems (files and directories) based on WebDAV (protocol for Web-based Distributed Authoring and Versioning). WebDAV claims to handle any resource accessible using a Uniform Resource Identifier (URI). However, there is a lack of applications which support distributed authoring of databases u...

BACKGROUND/AIMS The current study was designed to determine whether the indoor air pollution in a hemodialysis room (HD) was different from that of other comparable areas in a hospital. METHODS Five air monitor samplers were hung on the ceiling and placed on the table in both the HD and general ward nursing stations, respectively. In addition, five samplers were placed in the nurse's breathin...

Objective:Mold contamination of cakes and the possibility of mold growth can pose a serious health problem. Bakery products include various ingredients, which regularly contain molds. These microorganisms on cakes can come from the air, contaminated packaging materials and other sources.Methods: In this study, a total of 500 fungal isolates representing 36 species, were identified from cake sam...

The AeroEclipse® BAN (Trudell Medical International (TMI), London, Canada) was initially developed for use in the hospital environment, optimized for medication delivery using air or oxygen supplied at 50 psig pressure (2, 3). This article describes initial laboratory data with a version (AeroEclipse-XL®) optimized for operation by either table-top (OmbraTM table-top compressor, TMI, 230V AC ve...
