This standard specifies requirements and gives recommendations for sealing systems for centrifugal and rotary pumps used in the petroleum, natural gas, and chemical industries. See A.1.1 and A.1.2. It is the responsibility of the purchaser or seal vendor to ensure that the selected seal and auxiliaries are suitable for the intended service condition. It is applicable mainly for hazardous, flamm...

Automatic reasoning is applied to building design problems with a large number of standardized conditions, such as normal housing. Industrialized home building can provide quick-to-build low-cost dwellings, but these buildings often are not as appropriate for the local climate, building site or to the occupant needs as tailor-made homes. In this article we present a knowledge-based system (KBS)...

Quality assurance is a topical issue within the software industry, and various methodological solutions aimed at improving software quality have been proposed. Medical software is generally deemed safety-critical and, as such, should be subject to control procedures exceeding those applicable to general-purpose software. The user/purchaser of medical equipment has an important part to play in t...

The specification of an aluminum alloy for a cast component is based upon the mechanical properties it can achieve. For the designer and purchaser, it is vital to understand that the properties obtained from one particular combination of casting alloy, foundry practice and thermal treatment may not be identical to those achieved with the same alloy in a different foundry or with a different the...

Incarcerated students face a number of additional challenges to those faced by most other students studying at a distance. Lack of internet access is especially problematic for those studying in a sector that is increasingly characterised by online and flexible course offerings. In this paper, we report on a project that will attempt to address the digital challenges that hinder prisoner access...

This report forms, in two parts, deliverable D2.14 of the TurboNoiseCFD project. It describes the recommended innovative “triple plane pressure” in-duct matching strategy (TPP) at inlet and bypass duct side, and it describes in detail the newly developed and favourably tested CAA code for the propagation and radiation problem at the exhaust side. Due to the presence of the jet, this solution is...

There is growing international concern about the risks posed by direct-to-consumer advertising (DTCA) of prescription pharmaceuticals, including via the internet. Recent trade agreements negotiated by the United States, however, incorporate provisions that may constrain national regulation of DTCA. Some provisions explicitly mention DTCA; others enable foreign investors to seek compensation if ...

A differentiation between dynamic polarised protons close to tyrosyl radical sites in catalase and those of the bulk is achieved by time-resolved polarised neutron scattering. Three radical sites, all of them being close to the molecular centre and the heme, appear to be equally possible. Among these is tyr-369 the radial site of which had previously been proven by EPR.

AIB Insights Vol. 16, No. 1 The negoTiaTion of several mega-TreaTies in 2015, including the Trans-Pacific Partnership (TPP), the Trans-Atlantic Trade and Investment Partnership (TTIP), the EU-Canada Comprehensive Economic and Trade Agreement (CETA), and other regional agreements, has generated substantial public discussion about the protections and privileges afforded to multinational enterpris...

Time-periodic CFD simulations are widely used to investigate turbomachinery components. The triple-plane pressure mode matching method (TPP) developed by Ovenden and Rienstra extracts the acoustic part in such simulations. Experience shows that this method is subject to significant errors when the amplitude of pseudo-sound is high compared to sound. Pseudo-sound are unsteady pressure fluctuatio...
