For pump installation most experts recommend installing conventional metallic baseplates on concrete foundations and securing them to the foundation with a combination of anchor bolts and epoxy grout. Many papers have been written on the techniques required to obtain a good quality installation free of voids and properly bonded to the concrete and baseplate itself so as to give a long trouble-f...

Since time domain reflectometry (TDR) has been identified as one of the potential non-destructive methods for quality control of soil nailing works in 2003, further development work has been carried out. This report updates on the experience gained on the use of this technique to determine soil nail length. Various sources of uncertainty of a TDR test have been studied. They include human judge...

Rehabilitation of a watermain by grouted sliplining is usually carried out when the existing pipe is only partially deteriorated. Although designs that neglect the structural contributions from the existing pipe and the grout are generally conservative, the performance of the rehabilitated pipe needs to be better understood for effective design and management of buried water pipes. Presented in...

Air curtain is a widely used heat insulation equipment in the market, which reduces exchange efficiency of both sides by air surface formed jet. In order to reduce use electric heating device curtain, new designed coupling experiment source pump and heating. The fan preheated condenser pump, so as dependence on parts, save energy consumption.

Fine particulate matter is classified as a first-class carcinogen and receiving global attention. In particular, (PM2.5, PM10) are more fatal in students at growing age while their respiratory system develops than ordinary adults. During school hours, the main entrance often left open for convenience of staff. this situation, inflow PM2.5 through increases significantly. Thus, air curtains wide...

This paper presents the results of 12 tests on small-scale reinforced concrete beams strengthened in flexure with a single NSM carbon FRP bar. The used bar is novel commercial high values glass transition Tg and decomposition Td temperature to improve performance strengthening system at elevated temperature. bonded using cementitious grout rather than an epoxy adhesive. Flexural were performed ...

The new direction taken by the Common Agricultural Policy towards rural development, originating in the year 1992, was strengthened in the Agenda 2000 and re-intensified with the CAP reform 2003. Austrian agriculture followed this track very early and intensively, explainable because of the natural conditions and agricultural structures.
